분자단계에서 천연소재 유래 다당체는 면역 세포 표면(예, 대식세포)에 있는 한가지 또는 여러가지 수용체(${\beta}$-glucan 수용체, mannose 수용체, complement 수용체 3, Toll-like 수용체, scavenger 수용체)와 면역 반응을 시작하기 위하여 결합할 수 있고, 그 후에 신호전달을 위하여 cytokine과 second messenger($Ca^{2+}$, cAMP, cGMP, NO 등등)들을 생성한다. 그 결과로 선천면역과 적응면역을 유도하여 다양한 질환에 영향을 미친다. 추가적으로 다당체들의 면역조절은 신경내분비 체계의 조절과도 연관되어 있다. 최근 수많은 천연소재유래 다당체의 생리활성에 관한 연구가 진행되고 있다. 다양한 연구를 통해 정확한 약효, 낮은 독성과 부작용을 가진 일단의 다당체가 발견되어 현재 임상에서 암 치료에도 사용되고 있다. 이러한 사실들은 면역증진 다당체들이 항 종양치료를 위한 새로운 치료제로서 큰 시장을 개척할 수 있다는 가능성을 보여주고 있다. 이러한 사실에도 불구하고 현재 다당체에 대한 연구는 다음과 같은 취약점을 내포하고 있다. 첫째 다당체의 생리활성에 대한 정해진 비교기준이 없다. 특별히 임상 환경에서는 이러한 연구들이 중국, 일본, 한국과 일부 다른 동양국가들에 국한되어 있어 유럽이나 미국에서의 연구 자료가 결여되어있다. 둘째 현재 연구에 사용되고 있는 대다수의 천연소재 유래 다당체는 순수한 다당체가 아닌 천연 그대로의 것을 사용하고 있어 소재로부터 유래하는 다른 활성성분에 의해 쉽게 영향을 받을 수 있어 순수 다당체가 면역체계에 어떠한 역할을 수행하는지 진단하는데 어려움이 있다. 셋째 면역조절 경로에서 다당체의 정확한 신호전달 경로가 아직 정확하게 밝혀지지 않았고, 또한 동물과 임상실험에서 다당체가 작용하는 수용체 및 신호전달 경로에 대한 상반되는 결과가 발표되고 있기도 하다. 따라서 다당체의 면역조절활성에 대한 연구에 있어 다음과 같은 점들에 주목해야 할 필요가 있다. 첫째 다당체의 구조와 활성간의 상관관계를 밝혀야 할 것이다. 특히 다당체의 세부 구조 및 활성 부위를 밝혀낸다면 분자수준의 면역조절 기작을 명확히 하는데 도움을 줄 수 있을 것이다. 이러한 정보를 확보할 수 있다면 다당체의 구조를 변형시켜 활성을 증진시킬 수 있을 것이며, 또한 활성이 증가된 다당체를 합성하는 일도 가능해 질 것으로 예상된다. 마지막으로 ${\beta}$-glucan과 lentinan과 같은 정제된 다당체의 연구를 지속적으로 수행하여 효과적인 동물실험 및 임상실험 protocol을 확보하고 연구결과들에 대한 database를 구축해야 할 필요가 있다. 이러한 노력들이 성공적으로 수행된다면 천연소재유래 다당체들이 가까운 장래에 암 치료를 포함한 다양한 질병에 적용 가능한 새로운 면역조절제로 사용될 수 있을 것이다.

As the highly improved Internet and information technology has led to the diversification of users' demands, personalization service attract lots of attention as a means to meet highly diversified demand of users. However, personalization service costs a lot. Also concerns over a possible violation of privacy have been raised since the service uses technology to find out the users' profiles. This research studies the advantages individuals acquire from personalization service and how privacy concern influences service acceptance. Research on related documents and information gathering from e-commerce sites derived six representative types of service. Questionnaires were utilized to research privacy concern according to services, service usefulness, and service acceptance. As expected, privacy concern has a negative relation to acceptance while service usefulness has a positive relation to it, thereby resulting in an offset between two variables. Moreover, they play a different role depending on what kinds of service or in formation should be provided. The results derived from this paper will help the e-commerce sites provide personalization service by collecting personal information while protecting users' privacy.

This study seeks to discuss the effects of social support, acceptance of disability, and the sense of economic stability on the part of parents of children with developmental disabilities who are receiving treatment and training at a child development center has on family function. A survey was given to 252 parents of children who were using the child development center in S city. In the relationship between social support and family function, the mediating effects of the disability acceptance and the social support, the disability acceptance and the family function were used to verify the adjustment effect of the economic stability. The results of this study are as follows. First, as a result of checking the moderating effect of economic stabilization, social support, family function, disability acceptance and family function did not show any effect on economic stability. Second, as a result of verifying whether the relationship between social support and family function is mediated by disability acceptance, disability acceptance partially mediated the relationship between social support and family function. This study is significant in that it provided basic data for the development of a program to help children with developmental disabilities function properly.

Objective: The purpose of this study is to investigate the effect of mother's acceptance parenting attitude and optimism on children's self-regulation including cognitive, emotional, and behavioral regulation. Methods: The subjects were 361 3, 4, 5 - year - old children and their mothers who attended to the early childhood education institutions. One-way ANOVA was conducted to find out age differences in self-regulation. The regression analysis were conducted to find out whether the mother's optimism could predict their children's self-regulation. The stepwise regression analysis were conducted to find out whether the mother's acceptance parenting attitude could predict their children's self-regulation. Results: As for the self-regulation, there were significant age differences in the cognitve regulation and the behavioral regulation, but not in the emotional regulation. It implies that the abilities of cognitive and behavioral regulation increase as the age level goes up. As for the relations between mother's optimism and their children's self-regulation, only the permanence factor of the mother's optimism predicted children's cognitive, emotional, and behavioral regulation. As for the relations between mother's acceptance parenting attitude and their children's self-regulation, two components of mother's acceptance parenting attitude (unconditionally love & right) could predict children's cognitive, emotional, and behavioral regulation. The component of unique could predict the cognitive and emotional regulation. Conclusion/Implications: These results suggest that mother's optimism and acceptance parenting attitude positively affect on the development of self-regulation ability in children.

This study aimed to examine the effects of songwriting on the self-acceptance of adolescent in palliative care. Three participants were recruited from a university hospital in an urban area in South Korea. The songwriting intervention was conducted in six sessions, and each session was composed of an introduction, song writing and wrap-up. Participants were asked to complete the Unconditional Self-Acceptance Questionnaire (USAQ) before and after the intervention. Their verbal expressions and written song lyrics observed during the intervention were also measured. The results showed that the USAQ scores increased after the intervention, indicating the improvement in their acceptance of the self without judgement or high reactivity to feedback. In addition, the participants exhibited greater recognition of their emotions and acceptance of themselves as they are. They were also better able to discover internal resources and psychological competence. The participants reported that they could more freely express their emotions through song writing and that recording the songs they created was a means of communicating their feelings to others. Based on this study, it is expected that adolescents in palliative care will be able to experience self-acceptance through such brief song writing interventions.

In the post-catchup era, the probability of technology risk are growing according to technology innovation activities with high uncertainty are increasing. Risk acceptance and management are appearing as a more important policy issue. This paper examines the technology risk as a political and social sight and the character of technological risk in the post-catchup era. In the post-catchup, new technology and policy are more undergone trial and err. In particular, we need new approach and policy countermeasures to cope with risky environment and overcome catchup legacy. Accordingly, Korea risk management is needed reshaping of risk management system, increment of risk communication, risk management according to technology type, precautionary approach, bounded trial and err strategy, knowledge accumulation and learning reinforcement.
