We investigate computability of a self-similar set on a Euclidean space. A nonempty compact subset of a Euclidean space is called a self-similar set if it equals to the union of the images of itself by some set of contractions. The main result in this paper is that if all of the contractions are computable, then the self-similar set is a recursive compact set. A further result on the case that the self-similar set forms a curve is also discussed.

It is known (see [1, 3.1.5]) that the order type of the nonstandard natural number system * N has the form ω + (ω * + ω) θ, where θ is a dense order type without first or last element and ω is the order type of N. Concerning this, Zakon [2] examined * N more closely and investigated the nonstandard real number system * R, as an ordered set, as an additive group and as a uniform space. He raised (...) five questions which remained unsolved. These questions are concerned with the cofinality and coinitiality of θ (which depend on the underlying nonstandard universe * U). In this paper, we shall treat nonstandard models where the cofinality and coinitiality of θ coincide with some appropriated cardinals. Using these nonstandard models, we shall give answers to three of these questions and partial answers to the other to questions in [2]. (shrink)

While the world rushed to develop treatments for COVID-19, some turned hopefully to drug repurposing. However, little study has addressed issues of drug repurposing in emergency situations from a broader perspective, taking into account the social and ethical ramifications. When drug repurposing is employed in emergency situations, the fairness of resource distribution becomes an issue that requires careful ethical consideration.This paper examines the drug repurposing in emergency situations focusing on the fairness using Japanese cases. Ethical issues under these circumstances addressed (...) by the authors include: maintaining the evidence level, integrity of clinical research ethics, and voluntary consent by original indication patients. In order to address these issues, they argue that rapid accumulation of ethically and scientifically valid evidence is required, as is obtaining information on resource quantity. (shrink)

社会の平和的秩序は、その諸制度と構成員たちの協力により形成・維持される。第二次世界大戦後の日本においては、社会の急速な変動に伴って、人間関係が不安定になり、さまざまな局面で制度とのギャップから混乱が生 じてきている。新しい秩序の確立を軸にして、ジェンダー、人づくり、グローバリゼーション、社会保障などの現代的課題について考察する。.

When we examine the quality of life for each individual, several specific dimensions need to be considered. Health conditions and quality of family relationships are critical. When the individual in question is married, his/her marital quality is important. When he/she has a job, subjective assessment of that job is important. Social relationships regarding friends, neighbors, colleagues, relatives, etc. may be critical also. Although the quality of life is more than the sum of qualities of these specific areas of one's life, (...) it is still determined to a great extent by the qualities of these sub-areas, including marital and family relationships.

Japanese sociologistsCulture and social consciousnessclass, stratification, and mobilityindustry, labor, and organization’. Overall characteristics of sociological studies of Japanese society in Japan are summarized. The discrepancy between contemporary social phenomena and sociological research is also noted, using an example of freeters and neets, among others.

For ${b \in {^{\omega}}{\omega}}$ , let ${\mathfrak{c}^{\exists}_{b, 1}}$ be the minimal number of functions (or slaloms with width 1) to catch every functions below b in infinitely many positions. In this paper, by using the technique of forcing, we construct a generic model in which there are many coefficients ${\mathfrak{c}^{\exists}_{{b_\alpha}, 1}}$ with pairwise different values. In particular, under the assumption that a weakly inaccessible cardinal exists, we can construct a generic model in which there are continuum many coefficients ${\mathfrak{c}^{\exists}_{{b_\alpha}, 1}}$ (...) with pairwise different values. In conjunction with these results, we give a generic model in which there are many Yorioka’s ideals ${\mathcal{I}_{f_\alpha}}$ with pairwise different covering numbers. (shrink)

In 2002, Yorioka introduced the σ-ideal ${{\mathcal {I}}_f}$ for strictly increasing functions f from ω into ω to analyze the cofinality of the strong measure zero ideal. For each f, we study the cardinal coefficients (the additivity, covering number, uniformity and cofinality) of ${{\mathcal {I}}_f}$.

This study investigates the individual outcomes of irrational thinking, including belief in the paranormal and non-scientific thinking. These modes of thinking are identified through factor analysis of eleven questions asked in a large-scale survey conducted in Japan in 2008. Income and happiness are used as measures of individual performance. We propose two hypotheses. Previous studies in finance lead us to consider Hypothesis 1 that both higher belief in the paranormal and non-scientific thinking are associated with lower income. Literature on the (...) association between religion, the paranormal, and happiness suggest Hypothesis 2 that higher belief in the paranormal is associated with greater happiness, while higher non-scientific thinking is associated with greater unhappiness. To examine these hypotheses, we regress income and happiness on belief in the paranormal and non-scientific thinking with appropriate control variables. We employ the Mincer-type wage function as the income equation. Income, sex, and age are controlled in the happiness equation. Analysis supports both hypotheses, which highlights the complex features of irrationality. Although irrationality results in diminishing financial profitability, the component of belief in the paranormal improves the psychological state. (shrink)

DBS Think Tank IX was held on August 25–27, 2021 in Orlando FL with US based participants largely in person and overseas participants joining by video conferencing technology. The DBS Think Tank was founded in 2012 and provides an open platform where clinicians, engineers and researchers can freely discuss current and emerging deep brain stimulation technologies as well as the logistical and ethical issues facing the field. The consensus among the DBS Think Tank IX speakers was that DBS expanded in (...) its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. After collectively sharing our experiences, it was estimated that globally more than 230,000 DBS devices have been implanted for neurological and neuropsychiatric disorders. As such, this year’s meeting was focused on advances in the following areas: neuromodulation in Europe, Asia and Australia; cutting-edge technologies, neuroethics, interventional psychiatry, adaptive DBS, neuromodulation for pain, network neuromodulation for epilepsy and neuromodulation for traumatic brain injury.

Haptic-based vibrotactile biofeedback (BF) is a promising technique to improve rehabilitation of balance in stroke patients. However, the extent to which BF training changes temporal structure of the center of pressure (CoP) trajectories remains unknown. This study aimed to investigate the effect of vibrotactile BF training on the temporal structure of CoP during quiet stance in chronic stroke patients using detrended fluctuation analysis (DFA). Nine chronic stroke patients (age; 81.56±44 months post-stroke) received a balance training regimen using a vibrotactile BF (...) system twice a week over four weeks. A Wii Balance board was used to record five 30 s trials of quiet stance pre- and post-training at 50 Hz. DFA revealed presence of two linear scaling regions in CoP indicating presence of fast- and slow-scale fluctuations. Averaged across all trials, fast-scale fluctuations showed persistent dynamics ( = 1.05 ±.08 for ML and  = 0.99 ±.17 for AP) and slow-scale fluctuations were anti-persistent ( = 0.35 ±.05 for ML and  = 0.32 ±.05 for AP). The slow-scale dynamics of ML CoP in stroke patients decreased from pre-training to post-BF training ( = 0.40 ±.13 vs. 0.31 ±.09). These results suggest that the vibrotactile BF training affects postural control strategy used by chronic stroke patients in the ML direction. Results of the DFA are further discussed in the context of balance training using vibrotactile BF and interpreted from the perspective of intermittent control of upright stance. (shrink)

The author examines the character of the changes taking place in contemporary Serbian society. He emphasizes at the same time that contemporary Serbian philosophy is facing these crucial questions as well, which without it cannot be even addressed, let alone solved. The key difference between modern West European and contemporary Serbian societies, seen from the perspective of philosophy, is demonstrated most clearly in the manner of constituting institutions and transforming the modern Serbian society. In the process of building modern institutions (...) philosophy, not just in our country but throughout the Slavic East, has not had the role it played in Europe. Here lies the explanation why natural consciousness and an original ethos, though considerably modified, still remain unadapted and today represent a major obstacle to the establishment of the rule of European law. Without a change in the sense of justice and respect for the law it is impossible to accomplish the transformation of the society in which the law recognized by a democratic state could not be super ordinate to any reason. The crucial role of philosophy in this process is seen by the author not only in establishing modern European institutions and acceptance of the principle of European legislation, but above all in its influence on the transformation of the original ethos and establishment of new criteria on which the reflection, decision making and action of any individual would be based.. Autor u ovom radu nastoji da pokaze u cemu se sastoji sustinski karakter promenama koje se danas ostvaruju u savremenom srpskom drustvu, ukazujuci istovremeno, da i savremena srpska filozofija stoji pred tim sustinskim pitanjima, koja se bez njenog sudelovanja ne mogu na valjan nacin ni predociti, a kamo li da se mogu uvideti putevi njihovog razresenja. Kljucna razlika izmedju modernog zapadnoevropskog i savremenog srpskog drustva, sagledanog iz perspektive filozofije, najjasnije se pokazuje u nacinu konstituisanju institucija i nacina preobrazaja modernog srpskog drustva. U izgradnji modernih institucija filozofija, ne samo u nas, vec i na celom slovenskom istoku nije imala onu ulogu koju je imala u Evropi. U toj cinjenici nalazi se objasnjenje zasto su prirodna svest i izvorna obicajnost, iako znatno izmenjeni, ostali ipak neprilagodjeni i danas predstavljaju jednu od glavnih prepreka u uspostavljanju vladavine evropskog prava. Bez promene osecanja pravednosti i postovanja zakona nije moguce izvrsiti preobrazaj drustva u kojem pravo priznato od demokratske drzave ne bi moglo biti nadredjeno nikakvom umu. Kljucnu ulogu filozofije, autor ne vidi samo u uspostavljanju modernih evropskih institucija i prihvatanju nacela evropskog zakonodavstva, vec pre svega u njenom uticaju na preobrazaj izvornog etosa i uspostavljanje novih merila na kojima ce biti zasnovano promisljanje, odlucivanje i delanje svakog pojedinca..

Razmatranja o stanjima fizičkih odnosa materije, kretanja, prostora i vremena stoje u temelju relativističke fizike i, time, u središtu njezine moderne znanstvene ontologije. To i jest razlog filozofskih ispitivanja polja važenja ovih fundamentalnih, kategorijalnih pojmova teorije relativnosti, kako u znanosti fizike tako i u filozofiji, posebno u znanosti filozofije prirode. Jedno od takvih bitnih istraživanja ide i od pozitivističkih orijentacija u suvremenoj filozofiji, kamo zasigurno pripadaju, između ostalih, Russell, Frank, Bradley, Poincaré, Whitehead, Reichenbach, te pragmatist Bridgman. O nekima od (...) njihovih bitnih, primarno logičkih, epistemoloških i metodoloških stavova o teoriji relativnosti riječ je u ovom sažetom preglednom članku, koji nema pretenzija na sveobuhvatnost niti na iscrpnost izlaganja o ovoj neposrednoj stvari mišljenja.Considerations regarding the conditions of the physical relations among substance, motion and time are based on the physics of relativity and thereby placed in the centre of its modern scientific ontology. This explains the philosophical examinations of the validity of these fundamental categories of the physics of relativity in the science of physics as well as in the science of philosophy of nature. One of such essential investigations originated from the positivist orientation within the contemporary philosophy, to which Russell, Frank, Bradley, Poincaré, Whitehead, Reichenbach, and pragmatist Bridgman, among others, certainly belong. This review article examines some of their essential, mostly logical, epistemological and methodological standpoints. However, the aim of this article is not to comprehensively and in detail interpret this subject. (shrink)
