Attention has been focused recently on the concept of shared cognition which encompasses the notion that effective team members hold knowledge that is overlapping and complementary with teammates. This shared cognition is expected to improve team effectiveness. In contrast to the continued efforts in developing theoretical approach of shared cognition, empirical studies are meager. Thus, we conducted an empirical study to investigate the role of shared cognition on team effectiveness. This study classifies shared cognition into two types, team mental model and transactive memory system, by shared meaning. A total of 121 new product development teams in the IT industry were surveyed for the data collection. The results of analysis can be summarized as follows: first, team mental model has a positive influence on team performance, team innovative behavior and team learning effect. And the relation with team mental model and team performance is moderated by the similarity of knowledge structure among the expert. Second, transactive memory system has a positive influence on team performance, team innovative behavior and team learning effect.

Snap-buckling is one of the main failure modes of structures, because it will lead to the reduction of structural bearing capacity, durability loss and even structural damage. Boundary condition plays an important role in the research of engineering mechanics. Further discussion on the boundary conditions problems will help to analyze the dynamic and static behavior of structures more accurately. Therefore, in order to understand the dynamic and static behavior of curved beams more comprehensively, this paper mainly studies the nonlinear snap-through buckling and forced vibration characteristics of functionally graded graphene reinforced composites (FG-GPLRCs) curved beams with two different boundary conditions (including clamped-hinged and hinged-hinged) using Euler-Bernoulli beam theory (E-BBT). In addition, the effects of the curved beam radius, the GLPs distributions, number of GLPs layers, the mass fraction of GLPs and elastic foundation parameters on the nonlinear snap-through buckling and forced vibration behavior are discussed respectively.

nm23-H1 gene expression has been inversely correlated with tumor metastatic potential in certain tumors including melanomas, breast carcinomas, and hepatocellular carcinomas. However, its role with respect to the invasive behavior of central nervous system tumors has scarcely been addressed Because cell motility and invasion plays an essential role in metastatic dissemination, we have studied whether motile human glioma cell(U87MG) transfected with nm23-H1 complementary DNA have any alterations in their ability to migrate and invade. There was no significant changes in the shape and size of the cells following nm23-H1 transfection. The role of nm23-H1 in glioma migration and invasion have been evaluated by in vitro simple scratch technique and brain slice invasion model Basal migration ability of nm23-H1 transfectants cell(U87MG-pEGFP-nm23) were lesser than U87MG. Accordingly, U87MG-pEGFP-nm23 didn't migrate away apparently from the tumors implanted site comparing U87MG in brain slice invasion model. These results suggest that nm23-H1 may play an important role in suppressing the human glioma migration and invasion.

The purpose of the present study is to understand the change in the relation between mother-in-law and daughter-in-law according to the social change in comparison with the survey effects in 1974 (ko Jung-Ja) and 1985 to find out the cause of conflict in both side of power structure and affection structure, indicating behavior, the influences on the relationships among family, possible meditators. this thesis was made by an experimental research. Data were collected from 146 mothers-in-law and 141 daughters-in-law in Pusan. The collected data were analysed by statistical methods such is as follows, 1. cause of conflict In power structure the cause of conflict is, in the case of mother-in-law opinion opposion and shaughty attitude by daughter in-low and, in the case of daughter-in-law, domestic dominance. It is thought that there is a difference of viw\ew between mother-in-law and daughter-in-law about the possesion of economic dominance and many conflicts rises because of economic dominance. but the study in 1985 than 1974 suggests the possibility of conflict meditator because mother-in-law and daughter-in-law do homework dependently in the practice of power. In affection structure, the chief dissatisfaction toward daughter-in-law showes the change in time. In 1974, there was no affection and respect. In 1985, the rate of doing without consultation was high. Also, the lack of communication of mother-in-law and daughter-in-law is the cause of conflict. 2. Indicating behavior the rate of thinking alone if high in both sides. But in the survey of 1985, the covert verbal aggressive action with which mother-in-law appeals to her daughter and daughter-in-law to husband is rising. 3. Influence on the relationship among family by the conflict between mother-in-law and daughter-in-law. the conflict between mother-in-law and daughter-in-law play negative effects on the intimacy and relation between husband and wife. 4. Conflict mediation behavior As compremiser, it is suggested that in the case of daughter-in-law the position and role of husband is important and, in the case of mother-in-law respects mother-in-law, daughter-in-law and gives her the role.

It is assumed that the more society advances in its complexity and development, the more people pay attention to their health and accordingly the more people tend to practice health protective behavior. Most of human behavior is based on social inter-actions. The concept in Locus of Control has been developed from social learning theory to help better understanding the social phenomena affecting human behavior. Multidimensional Health Locus of Control is consisted of three dimensions: Internal, Powerful Others and Chance. This study was conducted to find out the health protective behavior patterns of the people and its relationship with Health Locus of Control as an influencing factor to their behavior. All the subjects in this study were the ones of the bank employees in Seoul, Among the total of 1,430 bank employees, 761 were chosen as a sampled subjects. Questionnair survey was conducted from March 4 to March 13, 1985. Research instruments used in this study were two kinds, one was the Health Locus of Control Scale developed by Wallston & Wallston and the other was the Measuring Scale for Health Protective Behavior developed by the investigator. Analysis of data was done by using Descriptive Statistics, X²-test, t-test, ANOVA, Pearson's correlation coefficient. The results of this study are summarized as follows: The mean score of Internal was 24.1, Powerful others was 19.7 and Chance was 15.3 out of maximum range of 6-30 respectively. The mean score of Health Protective Behavior Scale fell as 53.2 out of a maximum range of 18-90. Internals were more likely closely related with sex, educational levels and religion, Powerful others were related with age, educational levels and the number of family members. Chances were related with edu cational levels. The older the subjects were, the more concerned about their health. They tended to practice more favorable health protective behaviors. Furthermore, married people tended to fay more attention to their health than single individuals. Also, the number of family members and religion affected their attitudes in the health protective behavior patterns. Internals and Powerful Others were related with health protective behaviors. If one believes he can do something about his health and others play a significant role on his health, he is more apt protective patterns more suitable for health and actually shows that he is better off.

Alternative forms of travel have recently been delivering rewarding experiences and promising sustainable development for the tourism sector. However, it also depends on the uncertainties, consequences, and emotional connection with the destination. So far, the scholars have done limited empirical studies on volunteer tourism in Bali. Thus, this study tries to measure volunteer tourists' behavior by understanding the relationship between destination attachment, risk perception, and voluntourism behavior. Therefore, a study on the inclusivity of tourists' attachment to a particular place and perceived risks in volunteer tourism is an essential need to sustain the tourism industry. Data was analyzed using Partial Least Squares with smartPLS software. This study is based on a sample of ninety-three tourists of generation Z in Bali, Indonesia. Both outer model and inner model evaluation were conducted to ensure the robustness of the proposed model. The findings showed that destination attachment does have a direct and significant effect on voluntourism behavior. As expected, we also find that perceived risk has a significant moderating role on the relationship. Hence, greater efforts are needed to improve the image of the place by highlighting the characteristics of the locations. At the same time, it is necessary to put considerable effort to alleviate unfavorable conditions by creating safe environment surrounding the destination.

This study investigated the relations between mother's parenting self-efficacy, perceived social support, parenting behavior, and stress, and child's temperament, and child' self-esteem, including a mediational role of Korean mother's parenting self-efficacy. The participants were 404 Korean child-mother dyads living in Seoul, Korea. Structural equation modeling indicated that mother's parenting self-efficacy was a significant mediator of the relation between mother's perceived social support and child's temperament and mother's parenting behaviors including Warmth-Acceptance, Rejection-Restriction, and Permissiveness-Nonintervention. In the Warmth-Acceptance model, mother's parenting self-efficacy was related to child self-esteem through Warmth-Acceptance. In the Rejection-Restriction model, mother's parenting self-efficacy was related to child self-esteem both directly and through Rejection-Restriction. Child's temperament was also related to Rejection-Restriction directly. In the Permissiveness-Nonintervention model, mother's parenting self-efficacy was related to child self-esteem directly, not through Permissiveness-Nonintervention. Child's temperament, also, was related to Permissiveness-Nonintervention directly.

Air Traffic Control (ATC) towers play significant role in the functionality of each airport. In spite of having complex dynamic behavior and major role in mitigating post-earthquake problems, less attention has been paid to the seismic performance of these structures. Herein, seismic response of an existing ATC tower with a wall-frame structural system that has been designed and detailed according to a local building code was evaluated through the framework of performance-based seismic design. Results of this study indicated that the linear static and dynamic analyses used for the design of this tower were incapable of providing a safety margin for the required seismic performance levels especially when the tower was subjected to strong ground motions. It was concluded that, for seismic design of ATC towers practice engineers should refer to a more sophisticated seismic design approach (e.g., performance-based seismic design) which accounts for inelastic behavior of structural components in order to comply with the higher seismic performance objectives of ATC towers.

Purpose - This research aims to determine whether the consumer affinity and ethnocentrism as well as the image of a foreign country (Japanese product as the most popular product in Indonesia) are able to influence behavior related to the perceived risk and willingness to buy foreign products from the affinity country. Research design, data, and methodology - Using survey techniques with 164 respondents, the study uses structural equation model with confirmatory factor analysis (CFA). To ensure the research objective and appropriate respondent, then we select an individual who have interest on Japanese culture & language. The primary and secondary data used in this study. Primary data refers to information collected directly from respondent by questionnaires dissemination while secondary data is provided from well-established literatures. Results - The results show us that the ethnocentrism has dominant affection role compared to affinity in order to influence consumer behavior meanwhile, the product country image has cognition role to evoke consumer desire to consume foreign products. Conclusions - From a theoretical perspective, the study contributes to international marketing literature by refining the conceptualization of the consumer affinity construct and highlighting its multidimensional nature. The consumer affinity research need to enrich in term of the context and the different culture and situation.
