The corporate make an effort to improve organizational committment and the degree of employees' satisfaction(internal customer satisfaction). And If it's possible, it enhance competitive advantage of organization for external customer satisfaction. But in fact, the external customer satisfaction and competitive power is made by the complex function between leader support and organizational support in organization. Those hypotheses has been supported by the study of many scholars. Nevertheless the reliability in the results is not to be enough for certain conclusion. Therefore this study investigated the influence of organizational support and leader support(as a independent variable) on commitment(as a mediating variable) and citizenship(as a dependent variable). The result indicated that employees who perceive a high degree of organization and leader support show a high committment to organization in affection and positive OCB. Also the result showed that high committment to organization in affection enhance the relation between organizational support, leader's support and OCB(organization citizenship behavior) Implications for managers in organizations are suggested.

Despite the importance of prenatal nutrition, many studies find inadequate calcium intake among pregnant women. The purpose of this study was to investigate the value of the Theory of Planned Behavior in explaining the intentions and the actual consumption of milk among pregnant women participating in or eligible for WIC. A cross-sectional survey was conducted to collect information regarding attitudes, subjective norms, perceived control, milk allocation within the family, intentions and consumption of milk. The survey questionnaire was developed using open-ended questions and interviews with 112 pregnant women. One-hundred-eighty women recruited from prenatal clinics completed the survey questionnaire. Multiple regression was used separately to investigate the association of factors to intentions and to the consu-mption of milk, as proposed in the theory. Milk allocation within the family was used as an exploratory variable to explain milk consumption. Study findings revealed that all three factors, attitudes, subjective norms and perceived control contributed to the model in explaining intentions (explained variance : 36.2%), with perceived control being most important. For milk consumption, intentions and perceived control were related significantly to actual consumption, while milk allocation within the family was not (explained variance : 44.6%). These findings suggest that perceived control is important in understanding both intentions and milk consumption, providing empirical evidence for the Theory of Planned Behavior. With respect to the role of perceived control, more strong evidence was provided in explaining intentions. Findings suggest that educational interventions to increase milk consumption among pregnant women should incorporate strategies to enhance the perception of control, and to strengthen positive attitudes and to elicit social support from significant other.

The purpose of this case study was to construct a social context-based musical play program for children with high-functioning Autism Spectrum disorder (ASD) and to examine its applicability in improving the social skills of the children. The participants were a group of three children with high-functioning ASD with an average age of 9 years. The children participated as a group in 40-minute sessions that were implemented twice a week for 8 weeks. The children's social communication behaviors were observed during the sessions and analyzed in terms of sharing and exchanging their ideas and voluntarily interacting with peers and an adult (i.e., the researcher). The Social Skills Rating System (SSRS) was completed by the teachers of participants before and after the intervention. For all three participants, the occurrence of behaviors to exchange their ideas with peers and voluntarily interacting with an adult increased following the intervention. However, there were individual differences between the participants in terms of changes in each target behavior depending on their level of language and social skill development. These results suggest that social context-based musical play program may produce positive changes in voluntary communication with peers and play a significant role in expanding the scope of interventions that target the social communication of children with ASD.

This study is to suggest a new method of analyzing personality types of characters in narrative. First, we examined the history of the taxonomy of character types that existed in narrative theories so far. Until now, the classification of character types in narrative theory consisted largely of a formal classification based on roles in narrative, a content classification based on human internal qualities, and a complementary classification in which the two classification criteria are united. The problem with the existing character classification type is difficult to categorize it in spite of the usefulness of the content classification based on human internal qualities. On the other hand, the classification based on the role of the character in the narrative does not help as much as a practical analysis methodology because the classification is formal. In this study, we try to solve this problem by introducing Shalom Schwartz's human value type, and to make human character's value type and human role correlated with each other as a new character analysis methodology. Schwartz's study of value type is a very effective method to grasp the motivation of human behavior, and it seems to be very meaningful in analyzing the directivity of characters.

Massively Multiplayer Online Role-Playing Games (MMORPGs) are played by millions of people around the world. Within MMORPGs, players explore, solve mysteries, craft items, battle against dungeon or raid bosses, or compete against other players, all while using a variety of information and information behaviors. Role-players in MMORPGs develop identities and engage in interactive storytelling with other role-players as their characters. An ethnographic approach combining overt participant observation and engagement, semi-structured interviews, and artifact collection was used to explore and describe the social information behaviors of role-players through the lens of the theory of information worlds. The social types evident in the role-playing community in WildStar, a science fantasy-themed MMORPG, are closely interrelated to and differentiated by social norms and information values that dictate acceptable characters, stories, character actions, and appropriate lore sources as well as how to role-play without violating the boundary between in- and out-of-character information worlds. Role-players maintained the in-character and out-of-character boundary using a set of specific information behaviors to enable engaging and immersive role-playing experiences. Implications of the findings for the theory of information worlds as well as potential applications of role-playing and MMORPGs are also discussed.

Object：The purpose of this study was to investigate that infection with group $A[{\beta}]$ hemolytic streptococcus may associate the mechanisms that cause or exacerbate the tic symptoms in some cases of Tourette's disorder Method：Fourteen cases with abrupt worsening of tics participated in this study：10 males,4 females. The subjects were divided into two groups composing of the group with increasing level of ASO titer and the group with normal level of ASO titer. The subjects were administered Yale Global Tic Severity Scale(YGTSS). Result：The global severity scores and overall TS impairment rating scores of YGTSS in the group with increasing level of ASO titer were more higher than in the group with normal level of ASO titer Conclusion：These results suggest that increasing level of ASO titer, resulting from group $A[{\beta}]$ hemolytic streptococcal infection has affected worsening the tic symptoms in Touette's disorder.

본 연구는 기업이 기술제품을 도입한 후에 내부에 확산시키려고 하는 실행단계에서 직면하는 혁신저항에 영향을 미치는 요인과 혁신저항을 줄이고 확산을 증진시키는 확산촉진활동을 설명하여 2B 마케팅 상황에서 기술제품의 조직내 혁신저항-확산모델을 도출하였다. 기업에서 기술제품을 조직내에 확산시킬 때는 구성원들의 혁신저항을 접하게 된다. 소비자 행동에서는 혁신저항에 영향을 주는 변수로 개인변수와 제품변수를 제시하고 있지만 2B 마케팅에서는 조직구조변수와 구매센터변수가 추가적으로 영향을 주게 된다. 중앙집권화, 공식화정도가 높은 기업에서는 구성원들이 혁신저항을 가지면서도 사용할 수 있다. 이러한 경우에는 판매기업과 구매기업의 관계가 단기적인 관계로만 그칠 수 있다. 또한 구매센터 참여정도가 적고 구매센터가 집중화되어 있으면 혁신저항이 커지고 단기적인 관계만 형성될 가능성이 커진다. 그리고 제품의 지각된 위험, 적합성에 따라 혁신저항의 정도가 달라질 것이다. 그리고 사용자 개인의 지각된 자기능력, 현 제품의 만족도 등이 의미있는 조절 변수 역할을 할 것이다. 그러므로 장기적인 관계로 이어지기 위해서는 혁신저항을 줄이는 교육훈련, 제품개선, 부서간 조정, 개인적 동기 부여와 같은 확산촉진활동이 있어야 한다. 따라서 본 연구를 통해 판매기업과 경영자들은 기술제품에 대한 혁신저항을 극복하고 제품을 확산시킬 수 있는 학문적, 관리적 시사점을 얻을 수 있을 것이다.

d-amphetamine이 사람에서 paranoid schizophrenia와 아주 유사한 model psychosis를 일으키며 또한 사람과 실험동물에서 실제 정신분열증에서 뚜렷이 관찰되는 behavioral perservation을 일으킬 수 있음이 관찰되었다. 이에 많은 학자들은 이러한 양상의 행동변화가 정신분열증의 원인 추구에 중요한 의미를 주는 뇌변화를 반영할지도 모른다는 생각에 많은 연구를 거듭하여 왔다. 지금까지는 주로 catecholamine기전에 대하여 집중적 연구가 수행되어져 왔으나 최근에는 d-amphetamine의 약리기전의 일부는 5-HT기전이 차지하고 있으며, 여러 행동변화에는 catecholaimin 보다 5-HT 가 더 중요하게 관계하고 있다는 주장이 나오고 있다. 또한 d-amphetamine은 시험관내에서 MAO 특히 신경전달물질 분해요소인 A type를 가역적으로 억제할 수 있음이 보고되어 많은 흥미를 끌어왔으나 생체내에서의 억제여부는 직접적으로 확인이 되고 있지 않다. 그러나 최근에 Braestrup(1977)과 El Hait(1978)등은 간접적인 방법으로 생체내에서도 억제시킬 수 있음을 보고하고 있다. 이에 저자는 d-amphetamine에 의해 야기되는 행동변화와 그 밑바탕을 이루는 생화학적 기전에 5-HT가 차지하는 역할을 알아보기 위해서 다음의 실험을 시행하였다. 첫째, d-amphetamine의 급성, 만성 투여가 5-HT의 5-HIAA 로의 turnover와 MAO활성도에 어떤 영향을 미치며, 더 나아가서 이 양자사이에 어느 정도 상관관계가 있는지를 알아보기 위해서 d-amphetamine을 투여한 후 시간 경과에 따라서 뇌내 5-HT, 5-HIAA, 5-HT turnover rate와 MAO 활성도를 측정하였다. 둘째, d-amphetamine, 5-HT 합성을 증가시키는 약물과 합성을 억제시키는 약물을 투여하고, 위의 생화학적 실험과 행동관찰을 병합 실시하여 비교분석하였다. 그 결과는 다음과 같다. 1) d-amphetamine (6 mg/kg)을 급성투여시, 뇌내 5-HT함량이 투여 1시간 후에 최고로(대조치의 123%, p<0.001) 증가되다가 이후 감소하며, 5-HIAA 함량은 처음 15분부터 감소하기 시작하다가 30분에 최저로 떨어지며(대조치의 78%, p<0.005) 이후 증가하여 24시간째는 약간 대조치 이상으로 회복되었다. 미토콘드리아 MAO활성도는 1시간째에 최저로 떨어지다가(대조치의 89%, p<0.05)이후 회복하기 시작하여 24시간째에 약간 대조치 이상으로 회복되었다. 5-HT의 turnover rate는 MAO활성도 변화와 거의 같은 변화를 보였다. 2) 만성투여시 (하루 2번, 14일간 투여)는 5-HT 함량, 5-HIAA 함량, MAO 활성도 및 5-HT turnover rate 모두가 중등도로 감소되었다. (각각 대조치의 87%, 69%, 80%, 79%). 3) MAO 활성도와 5-HT turnover rate 사이에는 높은 상관관계가 있었다. (r=0.866, p<0.001, N=94). 4) MAO 활성도의 역동학 실험에서는 대조치에 비해 투여군에서 Km 값은 의미가 있는 증가가 있었으나 $V_{max}$값은 큰 변동이 없었다. 5) d-amphetamine을 급성 투여할때는 sleeping과 lying components는 상당한 감소를 보인 반면, locomotor activity 는 1시간까지는 상당한 증가를 보였으며 용량이 적을수록 더 큰 증가가 있었다. 반면 stereotypy는 1시간까지 용량이 증가할수록 더 큰 증가가 나타나서 locomotor activity에서 stereotypy 의 증가로 이행을 나타내었다. 만성 투여시는 locomotor activity는 점차적인 감소를 보였으나 stereotypy는 점차적인 증가가 나타나서 14일쯤에는 평형에 도달하였다. 6) PCPA 단독 투여군(400 mg/kg, 3번)에 있어서는 5-HT와 5-HIAA 함량의 상당한 감소가 나타났으나 MAO 활성도와 행동에는 큰 변화를 나타내지 않았다. PCPA전 처치군에 있어서도 5-HT와 5-HIAA 함량은 마찬가지로 상당한 감소를 나타내었으나 gnawing, sniffing과 locomotor activity는 더 증가를, stereotyped head weaving, forepaw treading과 hindlimb abduction은 상당한 감소를 나타내었다. 7) L-tryptophan(100 mg/kg)단독 투여시는 5-HT 함량은 약간 증가를 나타내었으나 5-HIAA 함량은 상당한 증가를 보였다. MAO활성도나 행동은 큰 변화없었다. L-tryptophan 전처치군에 있어서는 5-HT 함량은 더 큰 증가를 보였으나, 5-HIaa 함량은 MAO 활성도는 별 변화없었으며 stereotypedlateral head waving, forepaw treading 과 hindlimb abduction은 증가를, locomotor activity, gnawing과 sniffing components는 감소를 나타내었다. 8) d-amphetamine 단독투여, 혹은 L-tryptophan 전처치, PCPA 전처치후 측정한 5-HT 함량과 stereotyped head weaving, forepaw treading, hinilimb abduction components 사이에는 높은 상관관계가 있었다(r=0.789, p<0.001). 반면 5-HT 함량과 locomotor activity, stereotyped gnawing과 sniffing components 사이에는 약한 음성의 상관관계가 있었다. (r=0.554, p <0.005). 이상의 결과로 미루어 볼때 5-HT의 5-HIAA 로의 turnover rate 는 주로 MAO 활성도에 의해서 조절되며 5-HT 기전이 d-amphetamine에 의해서 야기된 여러 행동변화 중 상당한 부분에서 중요한 역할을 하리라고 생각된다.

Cyberspace is on its way to experience dynamic change, hereby encompassing technical and social diversities and multiplicities. The internet, with a history of no more than 10 years, has drastically changed the way, meaning and conduct of our lives, the structure and function of society and communication. Even in psychology, in which the purpose is to scientifically look into the human mind and explore its behavior, the in-depth inquiry into the human behavior and psychological features of the cyberspace have become an increasingly important issue. Research suggests that psychological features and concepts brought about during the process of communication in cyberspace have been influenced by the digital mode following the analogue one, and by the online mode following the off line one. It also suggests that, with new issues peculiar to information society, cultural structures should be re-conceptualized, reconstructed and reevaluated in various fields. This approach to the changing role, meaning and style within society should be rearranged and referred to as cyber psychology.

Benzodiazepines(BZDs) are among the most widely prescribed drugs in the world. They are potent anxiolytic, antiepileptic, hypnotic, and muscle relaxing agents. There is an emerging model of the role of several neural systems in anxiety and their relation to the mechanism of action of BZDs. It has been postulated that BZD drugs exert their anxiolytic action by regulating GABAergic transmission in limbic areas such as the amygdala, in the posterior hypothalamus, and in the raphe nuclei. The involvement of the amygdala in the behaviors triggered by fear and stress has been suggested by many previous studies. In this review, reports about regulatory effects of endogenous BZD receptor ligands on the perception of anxiety and memory consolidation were summerized. These findings further support the contention that BZD receptor ligands modulate memory consolidation of averse learning tasks by influencing the level of stress and/or anxiety that accompanies a learning experience. The findings suggest that the decrease in the limbic levels of BZD-like molecules seen after the various behavioral procedures represent a general response to stress and/or anxiety, since it occurs in proportion to the level of stress and/or anxiety that accompany these tasks. In addition, these findings further support the hypothesis that the $GABA_A$/BZD receptor complex in limbic structures plays a pivotal role in the stress and anxiety.
