Recently rapid urbanization facilitates development of high-rise building complex including apartment and office building in urban area. Many problems related with high -rise building are reported. Especially, unpleasant strong winds in pedestrian area are frequently encountered around the high-rise building. CFD simulation methods are used to analyze the wind environment of pedestrian level in high-rise building block. However, the results show differences between CFD and measurement. This difference is attributed to improper use of CFD. Conventional CFD simulation for wind environment around high-rise building does not describe the effect of trees, shrubs and plants near ground which affect the wind environment of pedestrian level. Canopy model can be used to reproduce the aerodynamic effects of trees, shrubs and plants near ground. In this paper, CFD simulation methods coupled with the tree canopy model to predict wind environment of pedestrian level in high-rise residential building block were suggested and the validity was analyzed by comparison between measurement and CFD results.

Objectives:The aim of study was to estimate the prevalence of poor sleep quality and depressive symptoms as well as to examine the moderating effect of positive psychology on the relationship between poor sleep quality and depressive symptoms among Korean university students. Methods:A total of 2,338(1,071 male and 1,267 female) university students at seven universities of four cities in Korea were randomly selected to participate in a survey. Data were collected by self-report questionnaires, including Pittsburgh Sleep Quality Index(PSQI), Beck Depression Inventory(BDI), Satisfaction with Life Scale(SWLS), Positive Psychotherapy Inventory(PPTI), and sociodemographic characteristics. Results:The prevalence was 44.8% for poor sleep quality and 14.4% for depressive symptoms among Korean university students. By moderated regression analysis, the results showed that poor sleep quality(β=0.453, p<0.001) aggravated depressive symptoms of university students, and life satisfaction(β=-0.087, p<0.001) and happiness(β=-0.145, p<0.001) respectively buffered the negative effect of the poor sleep quality on depressive symptoms. Conclusion:This study showed very high prevalence of poor sleep quality and depressive symptoms among Korean university students. Overall, these findings demonstrates that positive psychology can be effective in the enhancement of subjective and psychological well-being and may help to reduce depressive symptom levels. In the context of public health, positive psychology can be used as preventive, easily accessible and non-stigmatizing tools.

기후변화체제에서의 EU의 에너지 안보 전략과 성과

정수현(Soo Hyun Jung) 연세대학교 동서문제연구원 2016 동서연구 Vol.28 No.2

2000년대 말 EU는 에너지 안보를 강화하기 위해서 공급의 안정, 경쟁력 강화, 환경의 지속가능성이라는 에너지 정책의 세 가지 목표를 설정하고 이를 에너지 시장과 에너지 네트워크의 통합, 에너지 공급의 다각화, 온실가스 규제의 강화, 재생에너지 사용 확대, 에너지 효율성의 향상 등의 방식으로 달성하려고 한다. 현재까지 EU 에너지 정책의 성과는 사안마다 엇갈린다. 첫째, 에너지 시장의 통합은 점진적으로 지역적인 차원에서 진행되고 있지만 이를 기술적, 제도적으로 뒷받침해 줄 수 있는 유럽 국가들 간의 전력과 가스 수송시스템의 연결과 EU 차원의 통합된 규제는 아직 제대로 마련 되지 않았다. 둘째, 에너지 공급을 안정시키기 위해 추진했던 EU 내 에너지 생산의 증가와 에너지 수입다변화 정책은 별다른 성과를 거두지 못했다. 셋째, 2020년까지 에너지 체제의 지속가능성을 강화시키기 위해 설정한 온실가스의 20% 감축, 전체 에너지 사용량 중 재생에너지 비중의 20%로의 확대, 에너지 효율성의 20% 향상이라는 세가지 목표들은 거의 달성되었거나 될 것으로 전망된다. 이러한 성과들을 종합적으로 평가해 볼 때, EU의 에너지 안보는 환경적인 측면에서 많이 개선되었지만 공급의 안정이라는 측면에서는 아직 취약성이 많이 드러난다. Since the late 2000s, the European Union (EU) has established security of supply, competitiveness, and sustainability as the goals to enhance its energy security, and has pushed for the integration of energy networks and markets, the diversification of energy supply, the regulation of greenhouse gas emissions (GHGs), the encouragement of renewable energies, the improvement of energy efficiency to achieve those goals. By now, some objectives have been accomplished while others not. First, progress toward the integration of energy markets seems to be more regional than EU-wide, and technological and institutional support for a single energy market are not well provided. Second, the development of indigenous resources and the diversification of energy supply that have been taken to secure energy supply from Russia did not bring a successful outcome. Third, the key three key targets–20% cut in greenhouse gas emission, 20% of EU energy from renewable, and 20% improvement in energy efficiency–that the 2020 climate and energy package sets are expected to be completed by 2020. In sum, the EU has improved energy security regarding sustainability and environmental aspects; however, there are still vulnerabilities associated with the supply of energy that depends on Russian energy resources.

Social enterprises have received a great deal of attention from practitioners and academics. However, little researches have been conducted from social enterprise consumption`s values. We focus on relationships among social enterprise product`s consumption value(functional value, emotional value, social value, and rarity value), attitude and purchase intentions. We executed in two hypotheses. Our hypotheses are that social enterprise product`s consumption value can affect the consumer`s attitude and then the consumer`s attitude can affect the purchase intention. For this study, our research objects were university students as potential consumers. We investigated from Nov 1st to Nov 15th 2013, and used statistical program SPSS version 19.0 and SmartPLS statistical program. The results of this study are summarized as follows : First, the social enterprise product`s Consumption sub-factor(functional value, emotional value, social value, and rarity value) are positive. Among them, rarity value is very significant. Second, between consumer`s attitude and purchase intention are positive. In addition, consumer attitudes have a function of mediation between consumption value and purchase intention.

연구논문 : 유권자의 정치이념과 정당일체감이 환경의식에 미치는 영향력

정수현 ( Soo Hyun Jung ) 한국의회발전연구회 2015 의정연구 Vol.21 No.2

2000년대 이후 유권자들의 삶의 질과 환경에 대한 관심이 높아지면서 환경문제가 점차 주요 정치쟁점으로 부상되고 있다. 하지만 지금까지 한국의 환경의식 연구들은 인구사회학적 요인이 환경의식 형성에 미치는 영향력에 분석의 초점을 맞추면서 개인의 정치적 성향을 주요 변수로 고려하지 않거나 고려하더라도 측정 및 분석 방식에 문제를 가지고 있었다. 이에 따라 본 연구는 한국 사회과학데이터센터의 ‘국회의원 선거 유권자 조사’ 자료를 순서형 로지스틱 회귀분석(ordered logistic regression)을 통해 분석함으로써 유권자들의 환경의식을 결정하는 정치적 요인들이 무엇인지 살펴보았다. 그 결과 인구사회학적 변수들의 영향력을 통제했을 때 진보적인 성향이 강하거나 진보적인 정당에 정당일체감을 가지는 유권자일수록 친환경적인 태도를 가지는 것으로 나타났다. 이는 서구의 유권자와 같이 정치이념과 정당일체감이 한국 유권자들의 환경의식 형성에 중요한 요인으로 작용하고 있다는 것을 보여주는 것이다. This research examines the effects of voter ideology and party identification on environmental consciousness by analysing the 2012 Korean Congressional Election Studies data that Korean Social Science Center surveyed. My findings show that voter ideology and party identification have strong influence on environmental consciousness. Holding other variables constant, as voter ideology shifts to the left or if voters identify themselves with progressive parties, they are more likely to support environmental protection rather than economic development. Also, women and those with higher education are more likely to support environmental protection than men and those with lower education.

Nervous tissue engineering in combination with other therapeutic strategies is an emerging trend for the treatment of different CNS disorders and injuries. We proposed to use poly(L-lactide-co-glycolide)(PLGA) nerve channel impregnated demineralized bone particle(DBP) using tissue-engineering principles for the repair of spinal cord injury. We prepared DBP/PLGA nerve channel using ice particle-freeze drying method. Schwann cells(SCs), olfactory ensheathing cells(OECs) and bone marrow stromal cells(BMSCs) were seeded on DBP/PLGA nerve channel. The spinal cord was completely transected horizontally at two levels(T7 and T8), and DBP/PLGA nerve channel seeded cells was implanted in the lesion. For histological evaluation, the implants were removed after 2, 4 and 8 weeks and stained hematoxylin and eosin staining. Motor functional outcome measurements using the BBB scoring, sensory test and motor functional recovery test performed every week for 8 weeks post injury. It was observed that the effects of the DBP/PLGA nerve channel with cells(SCs, OECs and BMSCs), specially seeded SC on neuroinduction are stronger that DBP/PLGA nerve channel without cells and Blank control. In conclusion, these results suggest that SCs and DBP/PLGA nerve channel may have an important role for spinal cord regeneration of tissue engineering area.

Adult articular cartilage tissue has poor capability of self-repair. Therefore, a variety of tissue engineering approaches are motivated by the clinical need for articular repair. PLGA and hyaluronic acid(HA) has been widely used as biocompatible scaffolds materials to regenerate tissue. HA loaded PLGA scaffolds were prepared by a emulsion freeze-drying method. The chondrocytes were seeded on the HA-PLGA scaffolds and measured by MTT assay. Morphological observation, histology, biological assay for collagen and sGAG, and PCR were performed. In MTT assay result, scaffolds containing HA were higher cell viability then only PLGA scaffolds. Although collagen, sGAG, mRNA and collagen type II were greater than HA-PLGA scaffolds and collagen type I was less than HA/ PLGA scaffolds. When we cultured cartilage cell of rabbit in vitro, we observed better to keep the characteristic of cartilage cell in the HA-PLGA scaffolds than that PLGA scaffolds. This study suggests that HA/PLGA scaffold may serve as a potential cell delivery vehicle and a structural basis for in vitro tissue engineered articular cartilage.
