지식산업센터의 기업 간 커뮤니티 공간에 대한 연구 - 공공의 지식산업센터를 대상으로 -

The purpose of this study is to analyze and apply the intercompany community space of the Knowledge Industry Center to support start-up. In particular, public knowledge industry centers can focus on spaces that will stimulate residents creativity rather than commerciality through the use of space. The form of work of the Knowledge Industry Center varies from manufacturing to office, so community spaces can be arranged accordingly. This study examines various layout methods of community space through domestic and foreign cases and summarizes each application method.

Polyvinylalcohol 에 고정한 시금치 엽록체와 백금 촉매를 이용한 광수소 발생
박인호(In Ho Park),심은정(Eun Jung Sim),이진범(Chin Bum Lee),이혜주(Hye Joo Lee),엄경일(Kyung Il Um),선우양일(Yang Il Sunwoo) 한국식물학회 1993 Journal of Plant Biology Vol.36 No.4
Photoproduction of hydrogen by free and polyvinylalcohol (PVA)-immobilized spinach chloroplasts was investigated. Immobilization of chloroplast with PVA increased the functional stability of the chloroplast during storage. PVA-immobilized chloroplasts preserved photosynthetic electron transport activity much better than free chloroplasts. The hydrogen production of free chloroplast decreased to 17% of initial activity after storage of six days. The hydrogen production of the PVA-immobilized chloroplasts, however, showed 44% of initial activity after storage of 15 days. The maximal rate of hydrogen production was accomplished at 27℃ under the light intensity above 116 μE·m^-2·s^-1. The amount of hydrogen produced was proportional to the chlorophyll concentration. The hydrogen production was inhibited by DCMU treatment, indicating hydrogen production is dependent on photosynthetic electron transport. These results suggest that PVA is a good candidate for the immobilization matrix of chloroplasts for the photoproduction of hydrogen.

사회적 관계 내 자살경험과 가족이 자살생각 및 자살행동에 미치는 영향

본 연구의 목적은 가까운 사회적 관계의 자살경험이 자살생각과 행동에 미치는 영향을 실증적으로 분석하고 자살의 위험요인이자 보호요인으로서의 가족효과를 검증하는 데 있다. 이를 위해 전국 18세 이상의 남녀를 대상으로 수집된 2009년 한국종합사회조사(KGSS) 자료를 분석하였다. 분석결과는 사회적 관계 내의 자살경험이 응답자의 자살생각과 행동에 유의미한 영향을 미칠 수 있음을 보여준다. 즉, 가까운 사람 중 자살을 생각하거나 자살한 사람이 있는 응답자의 경우 그렇지 않은 응답자에 비해 자살을 생각하거나 계획할 확률이 높았다. 또한 가족요인이 응답자의 자살생각 및 행동에 강한 영향을 미치는 것으로 드러났다. 가족스트레스가 높을수록 자살생각, 자해충동, 자살계획 및 자살시도를 할 확률이 높았으며, 반면 가족지지에 대한 기대가 높을수록 자살생각, 자살계획 및 자살시도의 확률은 감소하였다. 본 결과는 사회적 관계를 통한 자살확산의 가능성과 자살에 대한 가족의 이중적 효과를 보여준다. 이는 현재 한국사회의 자살률이 계속적으로 증가하고 있는 상황에서 가족 등 가까운 사회적 관계의 건강성에 주목할 필요가 있다는 것을 의미한다. 더불어 사회적 관계 내 자살을 경험하는 사람들이 자살위험에 노출될 가능성이 높다는 사실은 이러한 취약집단에 대한 정책적 배려가 필요하다는 사실을 말해준다. The goals of the study were to examine if and how exposure to suicidal factors in social relationships affects suicidal ideation and behaviors and also analyze how family factors are associated with suicidal ideation and behavior. Data drawn from Korean General Social Survey(KGSS) collected in 2009 were analyzed. The findings show that exposure to the suicidal factors have statistically significant effects on suicidal ideation and behaviors. In the findings, respondents who have experiences of which socially close persons have suicidal ideation or completed suicide are more likely to have suicidal ideation and suicidal plan even in the models for which demographic factors and depressive symptoms are controlled. Also, family factors have significant effects on suicidal ideation and suicidal behaviors. Family stress increases suicidal ideation and behaviors whereas expectation on family support reduces the likelihood of having suicidal ideation and behaviors. This study shows that there might be possibility of behavioral contagion in terms of suicide through social connections and family has both positive and negative aspects on suicidal ideation and behaviors. Our study suggests policy implications for people who were exposure to suicide.
