This study argues that it is more important to enlighten human mind than to develop key competencies in terms of human development. For this, the current study addresses the limitations of OECD's functional approach to competency development, by exploring the conceptual framework of key competencies identified by OECD researchers. Then, it explores the structure of human mind, drawn from the perspective of the Doctrine of the Mean (中庸) which is one of the important East Asian philosophical traditions that has studied (...) the theme of human being or mind. When based on the analysis of the structure of human mind which uses the perspective of the Doctrine of the Mean, this study found that key competencies that a human being should have are basically produced through the operation of human mind. Also, human mind in the Doctrine of the Mean is 'transformed being' from ego-centered to virtue centered. The findings of this study provide some useful implications for the human development. First, given the nature of the human mind and the important role it plays in human life, the primary focus of education should be placed on enlightening the mind of human beings. Second, this study suggests that school education and extra-curricular activities should not only provide knowledge and techniques that are needed in a modern society, but also make an effort to enlighten human mind.

This study investigated the neuropsychological profile of college students who engage in binge drinking using comprehensive neuropsychological tests evaluating verbal/non-verbal memory, executive functions, and attention. Groups were determined based on scores on the Korean version of the Alcohol Use Disorder Identification Test and Alcohol Use Questionnaire. There were 79 and 81 participants in the BD and non-BD groups, respectively. We administered the Korean version of the California Verbal Learning Test and Rey-Osterrieth Complex Figure Test to evaluate verbal and non-verbal memory, (...) respectively, and measured executive functions using the Wisconsin Card Sorting Test, Trail-Making Test, Controlled Oral Word Association Test and Stroop Color-Word Test. We administered the d2 test to evaluate attention. Neuropsychological performance was analyzed by multivariate analysis of variance. The BD group showed significantly poorer performance in the long-term free recall condition of the K-CVLT and delayed recall condition of the RCFT and completed significantly fewer categories on the WCST than the non-BD group. In addition, there were significant negative associations among the AUDIT-K total score, AUQ binge score, and long-term free recall score of the K-CVLT. There were significant negative associations between the total AUDIT-K score and delayed recall RCFT score, and between the total AUDIT-K total score and numbers of completed categories on the WCST. These results indicate that college students who participate in BD have difficulties with verbal/non-verbal memory and executive functions, and further suggest that excessive alcohol use could have detrimental effects on the hippocampal-prefrontal circuit even with a relatively short period of alcohol use.

This paper studies the state of charge estimation of supercapacitors and lithium batteries in the hybrid energy storage system of electric vehicles. According to the energy storage principle of the electric vehicle composite energy storage system, the circuit models of supercapacitors and lithium batteries were established, respectively, and the model parameters were identified online using the recursive least square method and Kalman filtering algorithm. Then, the online estimation of SOC was completed based on the Kalman filtering algorithm and unscented Kalman (...) filtering algorithm. Finally, the experimental platform for SOC estimation was built and Matlab was used for calculation and analysis. The experimental results showed that the SOC estimation results reached a high accuracy, and the variation range of estimation error was [−0.94%, 0.34%]. For lithium batteries, the recursive least square method is combined with the 2RC model to obtain the optimal result, and the estimation error is within the range of [−1.16%, 0.85%] in the case of comprehensive weighing accuracy and calculation amount. Moreover, the system has excellent robustness and high reliability. (shrink)

It is widely agreed that China is experiencing a substantial transition toward modernization. However, both business behavior and day-to-day life in China are still greatly influenced and regulated by the traditional culture that has been embedded in Chinese society for thousands of years. Therefore, when studying social phenomena in China, researchers must take the indigenous cultural context into account. Focusing on the young generation in China, the authors explore the relationships between the most fundamental traditional concepts and various value dimensions. (...) Three hundred and thirty-two university students in Southeast China took part in the survey and data were analyzed with SPSS. The result might help both scholars and practitioners to better understand the contemporary Chinese culture. The discussion and implications are also offered. (shrink)

ObjectiveTo elucidate the clinical, radiologic characteristics of Leber’s hereditary optic neuropathy (LHON) associated with the other diseases.Materials and methodsClinical data were retrospectively collected from hospitalized patients with LHON associated with the other diseases at the Neuro-Ophthalmology Department at the Chinese People’s Liberation Army General Hospital (PLAGH) from December 2014 to October 2018.ResultsA total of 13 patients, 24 eyes (10 men and 3 women; mean age, 30.69 ± 12.76 years) with LHON mitochondrial DNA (mtDNA) mutations, were included in the cohort. 14502(5)11778(4)11778 (...) &11696(1)12811(1)11696(1)3460(1). One patient was positive for aquaporin-4 antibody (AQP4-Ab), and two were positive for myelin oligodendrocyte glycoprotein antibody (MOG-Ab). Three patients were associated with idiopathic optic neuritis (ON). Two patients were with compression optic neuropathy. Three patients were with the central nervous system (CNS) diseases. One patient was with proliferative diabetic retinopathy (PDR) and one with idiopathic orbital inflammatory syndrome (IOIS). At the onset, visual acuity (VA) in eighteen eyes was below 0.1, one eye was 0.5, five eyes were above 0.5, while VA in sixteen eyes was below a 0.1 outcome, three eyes experienced moderate vision loss. MRI images showed T2 lesions and enhancement in nine patients who received corticosteroids treatment; additional immune modulators treatment was performed on two patients. None of the patients had relapse during the follow-up time.ConclusionLeber’s hereditary optic neuropathy can be accompanied with multiple-related diseases, especially different subtypes of ON, which were also exhibited with IOIS and compression optic neuropathy for the first time in this cohort. This condition may be a distinct entity with an unusual clinical and therapeutic profile. (shrink)

Calibration errors are inevitable and should not be ignored during the estimation of item parameters. Items with calibration error can affect the measurement results of tests. One of the purposes of the current study is to investigate the impacts of the calibration errors during the estimation of item parameters on the measurement accuracy, average test length, and test efficiency for variable-length cognitive diagnostic computerized adaptive testing. The other purpose is to examine the methods for reducing the adverse effects of calibration (...) errors. Simulation results show that calibration error has negative effect on the measurement accuracy for the deterministic input, noisy “and” gate model, and the reduced reparameterized unified model; the average test lengths is shorter, and the test efficiency is overestimated for items with calibration errors; the compensatory reparameterized unified model is less affected by the calibration errors, and the classification accuracy, average test length, and test efficiency are slightly stable in the CRUM framework; methods such as improving the quality of items, using large calibration sample to calibrate the parameters of items, as well as using cross-validation method can reduce the adverse effects of calibration errors on CD-CAT.

BackgroundAttention deficit hyperactivity disorder is clinically diagnosed; however, quantitative analysis to statistically analyze the symptom severity of children with ADHD via the measurement of head movement is still in progress. Studies focusing on the cues that may influence the attention of children with ADHD in classroom settings, where children spend a considerable amount of time, are relatively scarce. Virtual reality allows real-life simulation of classroom environments and thus provides an opportunity to test a range of theories in a naturalistic and (...) controlled manner. The objective of this study was to investigate the correlation between participants’ head movements and their reports of inattention and hyperactivity, and to investigate how their head movements are affected by different social cues of different sensory modalities.MethodsThirty-seven children and adolescents with and without ADHD were recruited for this study. All participants were assessed for diagnoses, clinical symptoms, and self-reported symptoms. A virtual reality-continuous performance test was conducted under four conditions: control, no-cue, visual cue, and visual/audio cue. A quantitativecomparison of the participants’ head movements was conducted in three dimensions using a head-mounted display in a VR classroom environment. Task-irrelevant head movements were analyzed separately, considering the dimension of movement needed to perform the VR-CPT.ResultsThe magnitude of head movement, especially task-irrelevant head movement, significantly correlated with the current standard of clinical assessment in the ADHD group. Regarding the four conditions, head movement showed changes according to the complexity of social cues in both the ADHD and healthy control groups.ConclusionChildren and adolescents with ADHD showed decreasing task-irrelevant movements in the presence of social stimuli toward the intended orientation. As a proof-of-concept study, this study preliminarily identifies the potential of VR as a tool to understand and investigate the classroom behavior of children with ADHD in a controlled, systematic manner.

Information-sharing behavior is affected by identity recognition perception. The current study aims to delve into the impact of familiarity and anonymity on information-sharing behavior, and the mediating role of intrinsic motivations on WeChat Moments. We hypothesized a mediator role of intrinsic motivations in the relationship between an individual’s perceptions and information sharing. Based on the self-determination theory, a model was created and tested using a sample of 531 frequent users. In this study, these users were asked to use WeChat Moments, (...) the most popular mobile private social networking site in China. The results demonstrate the significance of familiarity and identifiability in an interpersonal relationship, when using social networking sites. Moreover, the influence of perceived anonymity on information-sharing behavior, which is entirely mediated by intrinsic motivation has been validated from an empirical perspective. Our findings extend previous studies by showing the totally mediated effect of perceived anonymity on information-sharing behavior on WeChat Moments and the influential mechanism of intrinsic motivation. The results will inform researchers about the importance of incorporating the interpersonal structural features and intrinsic motivation of social networking sites into future studies on online information-sharing behavior. Important ways to promote attention and share information involve building a familiar relationship with communities and equipping oneself with off-line relations. Final indications for future developments are provided, with a special emphasis on the development of these findings in various social networking sites contexts. (shrink)

The heterogeneity of transcranial direct current stimulation protocols and clinical profiles may explain variable results in modulating excitability in the motor cortex after stroke. However, the cortical electrical effects induced by different tDCS protocols remain unclear. Here, we aimed to compare rhythm changes in electroencephalography induced by three tDCS position protocols and the association between tDCS effects and clinical factors in stroke. Nineteen patients with chronic ischemic stroke underwent four experimental sessions with three tDCS protocols [anodal, cathodal, and bilateral ] (...) and a sham protocol, according to a single-blind randomized crossover design. Resting-state EEG was acquired before and after each protocol. First, a paired-sample t-test was used to examine the difference in spectral power between pre- and post-stimulation. Then, linear and quadratic regression models were used separately to describe the association between the clinical factors of stroke and changes in spectral power which was significantly different between pre- and post-tDCS. Finally, repeated measures analysis of variance with lesion hemisphere, stimulation protocol, and the location was performed to investigate the effects of tDCS over time. The induced effect of tDCS was mainly reflected in the alpha rhythms. The alpha power was increased by atDCS, especially low-alpha, in localized areas of the central and distant areas of the frontal and parietal lobes. Bi-tDCS also affected alpha power but in a smaller area that mainly focused on high-alpha rhythms. However, ctDCS and sham had no significant effects on any EEG rhythm. The clinical factors of time since stroke and motor impairment level were related to the change in high-alpha induced by atDCS and bi-tDCS following quadratic regression models. The above-mentioned modulation effect lasted for 20 min without attenuation. In conclusion, our findings provide evidence that the alpha rhythm of EEG is modulated differently by different tDCS protocols and that high alpha is affected by clinical characteristics such as post-stroke time and motor deficits, which is of great significance for understanding the modulation effect of different tDCS protocols on stroke and the guidance of protocols to promote motor recovery following stroke.

Climate change is difficult to connect with personally, because people only regard the phenomenon as important if it becomes a perceived threat to themselves. Arguments like statistics and policy debates are extrinsic motivators, which do not necessarily align people’s own intrinsic motives with those of climate action. Instead, narratives and visual communication can influence viewers implicitly by the way they show and reinforce actions and thoughts that align with climate action. In this design study, we used comics created for human-level (...) climate change influence to promote ideas like future-based thinking, sharing of responsibility, and caring for each other. We also created data visuals that illustrate future consequences of climate change for the purpose of averting negative alternative realities. To see whether our design can affect audience perception of climate change on the human level of goals and desires, we showed the comics to readers unfamiliar with the themes of the stories, presenting them as manga about characters and situations. The survey showed that data stories can affect the way naive readers interpret narratives to align with pro-climate attitudes such as sharing and future-vision, and that readers are focused on the human-level of the data and story as opposed to the physical resource level. Speculative fiction and data visuals provide a potentially effective way to influence individuals’ climate change attitudes by showing alternative realities and attributes of collective responsibility and planning-for-the-future as data stories.

Loving-Kindness Meditation (LKM) is an efficient mental practice with a long history that has recently attracted interest in the fields of neuroscience, medicine and education. However, the neural characters and underlying mechanisms have not yet been fully illustrated, which has hindered its practical usefulness. This study aimed to investigate LKM from varied aspects and interactions between the brain, the heart, and psychological measurements. A Buddhist monk practitioner was recruited to complete one 10-min LKM practice, in between two 10-min resting tasks (...) (pre- and post-resting) per experimental run. Two sets of single-channel wearable EEG devices were used to collect EEG data (placed at Fz and Pz) and heart rate simultaneously. A self-report evaluation was conducted to repeatedly record the comprehensive performance of mind and body in each session. EEG data were preprossessed and analyzed by EEGlab. Further statistics were made by SPSS. Spectrum analysis showed a significant increase of theta power (Fz: t = −3.356; p = 0.002; Pz: t = −5.199; p < 0.001) and decrease of heart rate between pre- and post-resting tasks (t = 4.092, p < 0.001). The analysis showed a negative correlation between theta power and heart rate (Fz: r = −0.681, p < 0.001; Pz: r = −0.384, p = 0.008), and a positive correlation between theta power and the self-designed report score (Fz: r = 0.601, p < 0.001). These findings suggest that LKM is accompanied by significant neurophysiological changes, mainly an increase in slower frequencies, such as theta, and a decrease in heart rate. More importantly, subjective psychological assessments were also correlated with objective neurophysiological measurements in a long-term meditator participant. During LKM meditation, this connection was stronger. The results of this case report have promising implications for LKM practice in daily life. (shrink)

The complexity of language is usually reflected in the complexity of sentences. At present, the research of sentence complexity mainly focuses on the analysis of syntactic complexity. In this paper, from the perspective of Leech's theory of sentence semantic structure, the predication structure is taken as the semantic unit to explore the sentence semantic complexity. The predication structures are extracted based on the result of sentence-based syntactic analysis, and then the linear expression sequence of a sentence is converted into a (...) semantic hierarchy based on predicate semantic frameworks; the universality of predicate semantic frameworks is obtained by using the spectral clustering algorithm; and the sentence semantic complexity depends on the universality of predicate semantic frameworks at various layers. The experimental results show that the measurement method of sentence sematic complexity based on predicate semantic frameworks is more effective by comparing with the method that only considers the semantic categories of words in the sentence.

Temporal Changes in Ovarian Gonadotropin-Releasing Hormone mRNA Levels by Gonadotropins in the Rat Sung Ho Lee, Eun-Seob Song, Sun Kyeong Yu, Changmee Kim, Dae Kee Lee, Wan Sung Choi l and Kyungjin Kim* Department of Molecular Biofogy and SRC for Cell Differentiation, Seoul National University, Seoul 150-742, Korea; IDepartment of Anatomy, College of Medicine, Gyeongsanf; National University, Chinju 660-280, Korea (Recei·. cd on December 29, 1993) The present study examines whether gonadotropins are involved in the regulation of ovarian GnRH (...) gene expression and how ovarian GnRH gene expression temporalJy correlates with alterations in hypothalamic GnRH, pituitary LH~ gene expression in respons to gonadotropins. Hypothalamic and ovarian GnRH mRNA and pituitary LH~ mRNA levels were determined by respective RNA-blot hybridizations, and ovarian GnRH and estradiol contents and serum LH levels were measured by respective radioimmunoassays. Three animal models such as 1) PMSG-treated, 2) PMSG and heG-treated immature rats and 3) proestrous stage of adult rats were used. Immature rats (25-days old) were administered with PMSG (10 iu) at 10:00 hand 48 h later with heG (10 iu) to induce ovulation. In the PMSG-injected model, hypothalamic GnRH mRNA levels were markedly augmented about 9-fold at 50 h, and pituitary LH mRNA 3-fold at 52 h after PMSG administration. Serum LH levels were increased to the preovulatory surge levels at 56 h, and ovarian GnRH mRNA levels were augmented 4-fold at 60 h after PMSG injection. Administration of heG also induced a marked enhancement in ovarian GnRH mRNA levels in comparison to the values shown in both intact and PMSGtreated rats at 52 hand 54 h, respectively. In the proestrous stage of normal adult rats, pituitary LH~ mRNA levels were peaked at 16:00 h. The preovulatory LH surge was evident at 4 h before increment in ovarian GnRH mRNA levels as shown in PMSG-treated rats. The present study clearly showed the sequential increase in hypothalamic GnRH mRNA, pituitary LH~ mRNA and ovarian GnRH mRNA levels, indicating that ovarian GnRH may play a possible role in the control of follicular maturation and the ovulation process.

Abstract:Retro-writing has ethical implications. How a speaking subject applies a retro-perspective frames a piece of writing within certain cultural discourses. In contemporary Chinese poetry, cultural nostalgia and the attempted revival of ancient aesthetics is a complex issue, one that is largely the result of a general interest in cultural archeology, writers’ anxiety of influence, the desire to escape from various political pressures, and the claim of a need for a distinctive Chinese cultural identity. The subject in many contemporary Chinese poems, (...) in many cases, is a male subject striving to retrieve the premodern holistic state of being, which is illusory. Han Bo’s two poems “Modern Sex Machine” and “Mass(ive) Killing Machine” are unique in that they examine the bludgeoning of modernity within postmodern parameters and attempt to map the dynamics of modern and contemporary subjecthood, which is in fact a transcorporeal experience of the subject as that which is, ultimately, subjectless. Such work, in creating a cross-corporeal subjectless subject, embraces alterity and renders possibilities for the reader to reject a prior unitary transcendental subject that is illusory, and thereby to discover the beings of themselves and their roles in the world—and to extend this work of reconfiguring subjecthood from literature into other aspects of social life.

The doctor in a foreign country is a recurring theme in physician writer Richard Selzer’s stories. In his 2009 novel, Knife Song Korea, Selzer returns to this theme, examining it in depth through the lens of gender. Selzer features the American military surgeon Sloane’s multiple border-crossings, namely, from America to Korea, from health to patienthood, and from sex-exploitation to love. Crossing those visible or invisible borders in the gender and race conscious contexts of medical profession and military in wartime (...) Korea, Sloane finds himself liminally located among various masculine stereotypes. The mixed-race situation in the novel further pushes Sloane to realize the unbearability of the baggage of American manhood as represented in his profession. Selzer’s punishment of Sloane’s border-crossings seems to suggest that physicians, together with patients, are equally likely to be victimized by the macho norms in medicine. (shrink)

Almost no trace of the eleventh-century Tibetan kingdom of Tsongkha remains in extant Tibetan materials; to write its history, scholars have therefore had to rely almost exclusively on Chinese sources written during the Song dynasty. This paper identifies a hitherto undiscovered colophon preserved in the Tibetan Bud- dhist canon as belonging to a translation that was produced through the patronage of the Tsongkha royal court in 1068 or 1080. This colophon provides the Tibetan versions of the names of the (...) Tsongkha king Dongzhan, the queen Xinmu, and their capital/palace. Not only does this new source offer us a valuable local insight into this mysterious Tibetan kingdom, it also raises questions concerning the perception of Tsongkha by Song Chinese literati and Central Tibetan clerics during and after the eleventh century. The paper proffers a description and interpretation of the ambivalent status held by this border region among its two neighboring regions. (shrink)
