In recent years the hikikomori (social withdrawal) phenomenon described in Japan has also come to be seen in Europe, particularly France. Despite the high level of interest in hikikomori in France, it has not been clearly defined and there is no clear overall understanding of the phenomenon. Our Japanese-French research team, supported by a Grant-in-Aid for Scientific Research (B) (overseas surveys), compared hikikomori youths in France and Japan from the perspectives of researchers in various fields. The aim of this study was to investigate the kinds of people to whom the concept of hikikomori is applied in France and Japan. A clinical conference was held in Paris in September 2010 to discuss cases considered to be hikikomori in the two countries. This article is an interim report from research in the first year of a series of international joint studies, and describes the commonalities and differences in the state of hikikomori in Japan and France.

Previous studies of motivation have assumed that in general, success breeds positive feelings and motivation while failure generates negative feelings and dampens motivation. However, a closer look at comments made by athletes in interviews reveals that in many cases, regret about losing a game can actually transform itself into a strong desire to win the next competition. In order to promote an academic study of the link between the feeling of not wanting to lose and motivation, this paper summarized the presentations and discussions that got underway at the Round Table Discussion, which was organized as part of the 2013 Japan Annual Congress of Sport Psychology. The authors described actual conditions and research perspectives of the "hating to lose" mentality based on the results of questionnaires, the expertise of elite athletes, and mental training for athletes". It is hoped that the Round Table Discussion will generate further research in this area.

In massed start bicycle races, riding in a group to avoid air resistance is profitable for racing cyclist to save their energy consumption. In this study, we estimated cyclists' power output and analyzed the relationship to the group size in a national championship of track cycling points race. The results show that the average velocity of the group increased as the number of riders in a group increased to some extent, but the average velocity of the large group decresed as the size of the group increased. These results suggest that the small groups are formed by cyclists intended to raise the pace and, on the other hand, the large groups are formed to save energy cunsumption by cyclists intended not to raise the pace.

Excretion of hypotonic sweat by eccrine sweat gland is achieved by re-absorption of NaCl by sweat duct which is an important function to prevent the salt loss and heat prostration. The Cl– transport by sweat duct is mediated by cystic fibrosis transmembrane conductance regulator (CFTR) anion channel. CFTR is the causative gene for cystic fibrosis, an autosomal recessive genetic disease. CFTR functions as a cAMP-dependent anion channel localized in the apical membrane of various epithelia. Loss of function due to severe mutations in both alleles causes typical cystic fibrosis characterized by dehydrated, thick, and viscous luminal fluid/mucus in the respiratory and gastrointestinal tract, pancreatic duct, and vas deferens. Cystic fibrosis is the most common genetic disease in Caucasians (1 per ~3,000 births) but it is rare in the Asian population including Japanese (1 per ~1.5 million). A compound heterozygote of mutations/polymorphisms (causing a mild dysfunction of CFTR) involves a risk of developing CFTR-related diseases (or atypical cystic fibrosis) such as chronic pancreatitis and male infertility due to congenital bilateral absence of the vas deferens (CBAVD). Recent studies suggest that CFTR mutations/polymorphisms are frequently found in Japanese patients with chronic pancreatitis, CBAVD and diffuse panbronchiolitis. Cl– concentration in the sweat is a useful measure of CFTR function in human. The sweat [Cl–] in healthy subjects is correlated with ages. High levels (>60 mM) of sweat [Cl–] suggest the dysfunction of CFTR.

The purpose of the study was to clarify what kind of impacts athletic club activities in university days have on job hunting and early stage career development around the 3rd year of employment through qualitative analysis, laying the concept of proactive as an analysis framework. The study interviewed Mr. A in the 3rd year of employment who belonged to an athletic club in his university days and started working after graduating from the first stage of the doctoral program. The interview revealed that Mr. A first found significance in having aspiration from his successful experience of getting into the college he had wanted to go after preparing for the entrance examination after failure in his first trial. So, he joined a triathlon club, which is one of athletic clubs, and proactively addressed organizational reform of the club and formed an organization which had not been established yet. Next, he worked on job hunting at his own responsibility and selected and joined a company in which he can utilize his specialized knowledge. After joining the company, he was assigned to the desired department where his strengths such as aggressiveness and leadership were highly evaluated in character evaluation. Furthermore, he is participating in corporate sports activities, deepening friendship with colleagues, and is positively involved in social contribution activities of the company. In this way, he is now living a fulfilling working life in the 3rd year of employment. As mentioned above, Mr. A has been selecting his behavior without shifting his principle “proactively behaving” and has been able to concretely demonstrate “proactive behavior”, that is, behavior by an individual of being actively engaged with an organization. Therefore, the hypothesis “students who are proactively participating in athletic club activities in university days enrich their university lives and aggressively conduct proactive behavior after starting working” has been validated. In addition, this study has proposed that the value of extracurricular activities in universities such as athletic clubs does not lie in belonging to an organization and instead it is necessary for a student to establish a self-sustained individual who has withdrawn from a “hierarchical system” in their voluntary activities. Studies of the impact of studying and other lives in universities on proactive behavior after starting working are meaningful, since almost no concrete or individual verification has been made on the theme because the theme began to gather attention recent years and few studies have been accumulated. However, this study is just one example, and a remaining future challenge is to proceed with the study focusing on various types of students. While various reforms have been promoted on university education, nothing is more important than proactive practices by students in formal curriculums and extracurricular activities in universities.

This study, focusing on the statement "Joining an collegiate sport club gives an advancement for employment", aims at clarifying how the difference in type of clubs as an extracurricular activity during college days affects the fulfillment of work and the work-life balance in the working adults' lives and how the difference in the current involvement status in sports relates to the working adults' lives. The research was conducted via internet for 800 working adults (400 males and 400 females) who are currently employed. The subjects were assigned to 4 categories regarding the activities at collegiate clubs or the others during college days: (1) those who belonged to sport clubs, (2) those who belonged to cultural clubs, (3) those who were involved in other activities, and (4) those who were involved in no activities. Statistical analyses were conducted using two-way variance analysis, ratio difference test, and logistic regression analysis. As a result, the following findings were obtained. The male subjects who currently play sports got significantly higher scores in the items related to fulfillment of work and the items related to work-life balance, which implies that sporting activities are a factor for living more positive working adults' lives. On the other hand, playing sports currently were not reflected in the items related to work-life balance for female subjects, which implies that the effect of sports may weaken in female workers' lives for being more difficult to balance work and housework/parenting. Next, regarding the statement "Joining an collegiate sport club gives an advancement for employment," it has been implied that the experience of playing sports as a part of their daily lives by joining an collegiate sport club during school days has led to realization of working adults' lives that achieve both the work and the sporting activities, and that this is the contemporary meaning of joining an collegiate sport club. In addition, the relationship between "those who currently play sports" and the promotion premium was also implied. These finding has helped demonstrate the necessity of encouraging working adults to participate in sporting activities.

This study considered the movements of the defense lines and the ball during a football game as a three-coupled oscillation. Each defense line of two opposing teams oscillated with in-phase synchronization, and the length between each defense line and the ball oscillated with anti-phase synchronization. We introduced a three-coupled oscillation model to understand these synchronizations. First, we considered the case in which three masses, m, and four spring constants, k, were equal in a three-coupled oscillation. We calculated the eigenvectors and eigenvalues based on the equation of motion, and we obtained three modes of oscillation as three angular frequencies in the equation. We obtained key parameters when we defined the initial state of the system, which allowed us to solve the equation of motion for three-coupled oscillation. Next, we considered cases in which three masses and four spring constants differed. To confirm the validity of the three-coupled oscillation model, we calculated the distribution of the relative phase between two outer masses, m1 and m3, as defense lines and the length between two outer masses and the middle mass, m2, as each defense line and the ball. The three-coupled oscillations showed similar distributions of the relative phase. However, the periodogram showed distinct periodicity. Thus, a more sophisticated model is needed to understand the behavior of the defense lines and the ball during football games.
