The objectives of this study were to explore food-related lifestyle segments of the older consumers, to identify its socio-demographic characteristics, and to investigate the differences in variables regarding health beliefs. A survey was conducted of adults 55 years of age and older living in Seoul, South Korea from March 28 to April 10, 2007. Out of the 500 distributed questionnaires, 361 were retained for final analysis: a response rate of 72.2%. As a result of cluster analysis, five consumer segments were identified; health-managing group, diet-unconcerned group, convenience-oriented group, taste-oriented group, unpracticed group. Significant differences were found among the five segments in terms of socio-demographic characteristics and variables regarding health beliefs (i.e., perceived self-efficacy, perceived barriers, perceived benefits). In the health-managing group and taste-oriented group, mean scores of perceived self-efficacy (p<0.001) and perceived benefits (p<0.001) were significantly higher than other groups. However, in the diet-unconcerned group and convenience-oriented group, the mean scores of perceived barriers (p<0.01) were significantly high. This study shows that foodservice operators targeting the older consumers should consider characteristics of each segment to develop a customized program.

This study examined the factors affecting the intention to use the wearable device consumers and the factors that have positive effects on the intention to use the wearable device or the consumers who have not yet used the wearable device. The purpose of this study was to examine the perceived usefulness, perceived usefulness, consumer individuality (individual innovation, self-efficacy, subjective norm) and wearable device characteristics (aesthetics, compatibility) of technology acceptance model (TAM). The results of the analysis are as follows. This study focused on the effect of consumers on the intention to use. (TPB) and Davis (1989) proposed technology acceptance model which is applied to various fields to predict the intention to use as it is proved validity and usefulness as a theory explaining various social behaviors. TAM) in order to examine the intention to use. In addition, we added consumer characteristics and variables related to product characteristics of wearable devices, which have not been studied much in previous studies.

The purpose of this study was to determine psychosocial variables of exercise behaviors for old adults. A major research problem identified through theory of planned behavior and it's empirical data: Do cognitive-social variables(health risk perception, self-efficacy, group conformity, exercise attitude) significantly mediate exercise behaviors(intention, action, maintenance)? A total of 453 older adults above 65 years(171 males and 282 females) who were enrolled in various classes were randomly selected at adults centers in Seoul. Participants completed a battery of questionnaires including the psycho-social variables(health risk perception, self-efficacy, group conformity, exercise attitude) and exercise behaviors(intention, action, maintenance). The results of statistical procedures(e.g., hierarchical multiple regression) indicated self-efficacy and exercise attitude significantly predicted exercise intentions of older adults. Exercise intention was a significant predictor of action, and action was a significant predictor of exercise maintenance. In discussion, various psycho-social mechanisms were provided to interpret the results of this study, and future directions were suggested.

The boycott of Japanese products triggered by Japan's economic retaliation has heated up the Republic of Korea. This study examined the factors affecting the boycott participation intention in 217 college students and ordinary people in their 20s and 30s. The results of the study showed that perceived egregiousness, self-efficacy, and subjective norm had a positive effect on boycott participation intention, and perceived egregiousness had an indirect effect on boycott participation intention through anger. In addition, these overall impacts were moderated by online and SNS news usage. This study is significant in providing academic and practical implications for understanding boycott phenomena by verifying various influencing factors on consumer boycott intentions and comprehensively reviewing the mediating effect of anger and the moderating effect of online and SNS news usage.

RPA is implemented through management policy and enforced in mandatory environments to enhance performance and efficiency in various fields. However, the success of RPA implementation depends on the level of active engagement from organization members, even in a mandatory setting. This study identifies perceived ease of use, usefulness, accountability, perceived risk, and self-efficacy as variables that influence conative use behavior, which consists of reflective secondary factors such as immersion, reinvention, and learning. Data was collected from 207 office workers in various industries who have experience with RPA to test the proposed research model. The structural equation was verified using SPSS 20.0 and SmartPLS 4.0, and the analysis showed that all the proposed variables had a significant impact on conative use behavior. Our research findings provide theoretical and practical implications in knowledge management, enabling companies that implement RPA to recognize and address factors that encourage their members to actively use RPA.

This study examined coping strategies and perceived changes of the Chinese international students in South Korea. A total of 56 Chinese students participated and data was analyzed using the concept mapping method. The results showed that Chinese international students adopted developing language proficiency and using social networks as important coping strategies. They also perceived a wide range of changes including changes in the cultural and personal self. However, the perception of these coping strategies and changes differed by the length of stay. Chinese international students who stayed longer reported using specific coping strategies for mood regulation, which was distinctive from the coping strategies used by students who stayed for a shorter period of time. Students who stayed longer perceived negative changes as well as positive changes, while students who stayed for a shorter period reported predominantly positive changes. The findings indicate that university staff needs to understand and sensitively respond to the distinctive experiences of Chinese international students which vary across time.

This research examined the relation between personal history of residential moves and psychological independence. In particular, this research tested how actual self-importance (vis-a-vis perceived social importance) of values (Study 1) and preference for uniqueness (Study 2) would vary as a function of past experience of moving. The results showed that personal history of residential moves was positively linked to actual self-importance of individualistic values and perceived social importance of collectivistic values. In addition, the results demonstrated that individuals with frequent residential moves generally showed a greater liking for uniqueness. The implications of these results for the direction of causation between residential mobility and psychological independence are discussed and suggestions for future research are made.

The purpose of this study was to examine the relations and analyze the mediation effect that exists between the feedback types by professors of university physical education and self-efficacy and sports continuance. The sampling method was used to survey physical education university students from three different universities located in the Greater Seoul Metropolitan Area. 309 samples were ultimately selected as valid samples. Data processing was carried out by using SPSS 18.0 and AMOS 18.0. The fidelity of the whole model was assessed through this process and then the theory was tested. The results were as follows. Firstly, if the perceived feedbacks by the professor were complimentary/encouragement and performance knowledge/positive nonverbal feedbacks it had a positive effect. Negative nonverbal perceived feedback had a negative effect forecast. Secondly, complimentary/encouragement perceived feedbacks by the professor did not have a meaningful impact on sports continuance index. Performance knowledge/positive nonverbal feedback resulted in static effect while negative nonverbal feedback had a negative effect. Lastly, self-efficacy served a meaningful mediation role in the relation between negative nonverbal feedback by the professor and sports continuance.

This study investigated the effects of social presence as means of self-awareness and interpersonal-awareness on the cyber-aggressive behavior. The cyber-aggressive behavior (flaming and direct aggression use of character) should be differ from existence of social presence and type of social presence of internet users. To test hypothesis, an experiment was executed a field study on cyberspace, an on-line game, "fortress 2 blue forever". I made a chat-room in the game site to conduct an experiment to 107 person who entered the chat-room and blinded ignorance of this situation made by researchers. As the subjects enter the chat-room, he chats with 3 researchers who were waiting before he gets in. The social presence was operated with 3 phases by the contents of the chat (①control group; nothing, ②experimental group 1; reaction about other people ③experimental group 2; reaction about other people + self-exposure by an exchange information of their home region). The studies show that, subjects of the control group behaved more aggressively than other subjects of the experimental groups(both flaming and direct aggression use of character). Meantime, I compared experimental group 1 with experimental group 2 to investigate difference between the type of social presence. As the result, subjects of the experimental group 1 behaved more aggressively than experimental group 2 (only flaming, there's no difference in direct aggression use of character).

지표위의 어떤 지점에서의 지구자기의 수평분력 방향과 진북방향 사이의 각을 편각(Declination)이라고 정의한다. 쉽게 말하면 편각은 나침반의 자침이 가러 키는 방향과 진북방향과의 사이 각을 말한다. 대부분의 사람들은 나침반의 자침이 북자기극(North magnetic pole)을 가러킨다고 잘못알고 있다. 지구 다이나모설(Geodynamo theory)에 의하면 주로 철(약 90%)로 구성된 외핵 속에서 계속 생성 유지되고 있는 복잡한 (각각 나선형(helical)의 회전축에 대체로 평행하거나 평행하지 않은) 대류(Convection currents)에 수반하는 전류가 복잡한 지구자기장을 형성한다. 지표상에서 측정한 지구자기장의 자료를 Spherical harmonic analysis 으로 분석하면 한 개의 커다란 쌍극자(Dipole) (Inclined geocentric dipole 또는 주된 자기장(Main field) 이라고 부름), 적도쌍극자(Equatorial dipole), 4극자 (Quadrupoles), 8극자(Octupoles) 등의 여러 개의 크고 작은 쌍극자들의 총합이 지구자기장의 근원인 것처럼 해석되고 있다. 어떤 지점에서의 지구자기장의 방향은 외핵에서 생성된 천체 자기장에서 Main field를 제거한 나머지 자기장과, 상부 맨틀(upper mantle), 지각 및 지표상에 존재하는 인공 물체 또는 암석 및 광석 등의 잔류자기 및 유도자기 그리고 지형 등의 영향으로 결정된다. 어떤 지점에서의 지구자기장의 방향은 태양풍(Solar wind)과 전리층 사이의 상호작용 등의 외부자장(external field)의 영향도 받는다. 비쌍극자 자장(Non-dipole field)은 지표상에서 측정되는 총자기장에서 외핵에서 생성된 주된 자기장(Main field) 즉, 지구의 회전축에서 약 11.5도 기울어진 쌍극자 자장을 제거하고 남는 자기장을 말한다. 따라서 편각은 비쌍극자자장의 영향을 가장 많이 받는다. 비쌍극자 자장은 정지한 상태의 자장(standing field) 과 매년 서쪽으로 약 0.2도 움직이는 Westward drift하는 자장으로 크게 두 가지로 구분된다. 쌍극자 자장의 방향은 매우 느리게 변하지만 그 세기는 현재 비교적으로 빠르게 약해지고 있다. 비교적으로 매우 빠르게 변하는 비쌍극자 자장의 변화를 영년변화(Secular variation) 이라고 한다.
