  • Objectives : The researcher investigated the anti-obesity effect of Platycodi Radix (P), Platycodi Radix and Cyperi Rhizoma combination water extract (PC) in mice fed a high fat diet and focused on the analysis of local area adipose tissue.Methods : Male ICR mice were divided into four groups, which were fed either a normal AIN diet (N group), a high fat diet (HFD group), or a high fat diet and orally administration with a concentraion of 300 mg/kg body weight (P group or PC group) for eight weeks.Results : Compared to mice in the HFD group, mice in the P group or PC group showed significant reductions in weight gain and relative weight of total fat. Compared to mice in the HFD group, mice in the P group showed significant reductions in relative weight of liver. In blood biochemistry analysis, AST, ALT, triglyceride, total-cholesterol and low density lipoprotein(LDL)-cholesterol, AI levels of P group or PC group were significantly lower than those of the control group AI. But serum serum high density lipoprotein(HDL)-cholesterol levels from the P group or PC group were significantly higher than those of the HFD mice in serum. And serum adiponectin levels from the P group or PC group were significantly increased that those of the HFD mice. And adipocyte number in the fat tissue from the P group or PC group was significantly higher than those of the HFD mice.Conclusions : Platycodi Radix, Platycodi Radix-Cyperi Rhizoma have an anti-obesity effect in mice and the effect is mediated by inhibition of fat gain.

  • Indonesia is a mega-biodiversity country having at least one trillion US Dollars value of biological resources per year over the next 20 years. Indonesia is home to 11 percent of the world's flowering plant species and 12 percent of all mammals. Many of Indonesia's species and more than half of the archipelago's endemic plant species are found nowhere else on the Earth. This information is just a small portion of all higher plants and animals being found in Indonesia. Former studies described that total number of species in Indonesia is estimated more than 1,000,000 and most of them remain unknown scientifically. Most of lower plants and animals have not been studied yet, so that greatest portion of Indonesia's biological resources has never been assessed with respect to its economic value or conservation status. Many developed countries are building cooperation with Indonesia on resources, mainly in the fields of grant aid, socio-economic services, R & D, researcher exchange, technology transfer, infrastructure, education/training, finance, etc. Indonesia will obtain greater benefits and management of its biological richness via increasing its international capacity to add value and information to its biological diversity. These goals can be achieved by close international collaboration on search of important biological resources and other bioactive products that have potential economic values. Development of biological resource-based technology stands as the industry of the $21^{st}$ century and, therefore, Indonesia has a unique opportunity to lead the process in the world.

  • As office workers tend to spend more time indoors nowadays, the importance of physical environments has been emphasized. Those who work longer hours in the office are likely to get more stress from the environments. A number of studies have proved that the plants (natural elements) were effective in relieving stress. Therefore, it is concluded that interior landscape is effective on enhancing the psychological wellbeing of office workers. The purposes of this study were as follows: (1) to determine the best modulized designs through rating psychological indices, and (2) to prove its effectiveness by applying those designs onto actual office environments. This study was conducted from April, 2012 to November, 2012. The subjects of the study were comprised of 154 juniors and seniors in Seoul Women's University. They are university students who are seeking jobs upon graduation. To this end, field investigations, surveys, and literature reviews were conducted. The results of the study indicated as follows: First, the most optimal models for psychological wellbeing have been derived. Second, the interior landscape had a positive effect on the psychological wellbeing of the office workers. On the basis of these findings, interior landscape with greens plays a big role in promoting the psychological wellbeing of the office workers. Also, its effect can be maximized when modulized design is combined with interior landscape. The limit of this study lies in its simplicity of design elements as emotional design aspects were quantified for statistical processing. In the near future, further studies focusing on various design elements need to be carried out. To sum up, the researcher hopes that these findings contribute to psychological recovery of the office workers, and interior landscape becomes more prevalent in the workplace.

  • This study has analyzed overseas projects of building rural communities using vacant houses. It is aimed at identifying the roles of NPO in the community-building projects and providing implications applicable to Korea. In recent years, there has been a spike in the number of vacant houses in rural areas. It is due to rapid urbanization and uneven distribution of the population across the country. Those are the reasons that prompted community-building projects. To solve the vacant house issue, there has been rising interest in building communities through vacant houses as rural resources and effectively integrating them as useful resources. However, the roles of key entity that pursues community-building projects using vacant houses have not been discussed sufficiently. Thus, this study deals with the 'Vacant House Recreation Project of NPO Corporation in Onomichi' in Hiroshima, Japan. Through the case study, the following are introduced as NPO's roles in community-building projects using vacant houses. First, pursuing promotion and attracting attention by making the utilization of vacant houses sensational; system improvement; offering information. Second, enhancing the perception of local residents by offering local services using vacant houses; offering community-building items. Third, forming a place of public discussion to solve conflicts during community-building projects using vacant houses; offering alternatives to building communities. Above all, such roles have led to the key status of NPO during its community-building projects using vacant houses. It offers the following implication for Korea: Future vacant house-related policies for rural revitalization should be done from community-building standpoint and include establishing the roles of NPO.

  • Objectives: This study was conducted to analyze the trends of government R&D (R&D) projects related to laboratory safety over the past 20 years. Methods: We collected publications from various databases(DBs) with words such as laboratory(ies), lab(s), researcher(s), laboratory worker(s), safety, environment, hazard(s), risk(s), and so on. Selected publications were analyzed by the research funds and the number of projects according to the investment subject and research characteristics. Results: About 93% of the total R&D budget went to government policy projects, not scientific research. Second, from the perspective of 'safety management activities', most of the research is related to management and inspection at the organizational level. Issues that need to be discussed at the national level like policy governance are not included. Third, focusing on the 'safety management cycle', there were few studies related to 'prediction' or 'post-response'. Fourth, when an analysis framework combining the perspectives of 'safety management activities' and 'safety management cycle' is applied, most of the budget is spent on infrastructure such as digital management systems, whereas basic knowledge for prevention and production of evidence was very few. Conclusions: In order to prevent policy planning without policy evaluation, implementation without strategy, and evaluation without evidence, it is necessary to expand investment in empirical research on risks, research on the effectiveness of current application methods, and research on theory development. The government budget for laboratory safety-related projects should be managed separately from the R&D budget for scientific research. Although less than 5% of the budget allocated to scientific research is the total budget, an optical illusion occurs because both the project budget and the scientific research budget are counted as R&D budgets.

  • 2007년 개정교육과정에 의해 초등학교에서 프로그래밍 교육이 실시되어야 하나 여러 현실적인 제약으로 인해 잘 이루어지지 않고 있다. 초등 프로그래밍 교육은 EPL로 실시하는게 적합하며 스크래치 프로그래밍은 개발된지 얼마되지 않았으나 쉬운 인터페이스와 블록을 활용한 구문작성, 멀티미디어적인 요소가 들어있는 결과물을 작성할 수 있는 등의 장점으로 인해 초등프로그래밍 교육에 적합하다. 본 연구자는 초등학교 4학년을 대상으로 1학기 12주간 스크래치 프로그래밍을 지도한 결과를 바탕으로 스크래치 프로그래밍의 지도안과 교육방법을 정리하고 그 결과를 분석하였다. 스크래치 프로그래밍이 학생들의 흥미를 높이고 창의성과 논리성을 향상시키며 과학적 태도를 함양 시키는데 도움을 줄 수 있다는 결과를 얻었다. 초등EPL교육을 위한 스크래치 프로그래밍은 효과적이며 지도할 때 학생들의 선행지식이나 남녀의 흥미도에 의해서도 학업 성취의 편차가 있으므로 수준별 개별학습이 가능하도록 학습 프로그램을 구성할 필요가 있다. 그리고 결과물의 제작에 앞서 충분한 사고와 토의할 시간을 주어 프로그래밍 교육의 목적을 살리도록 해야할 것이다.

  • 본 연구는 성별에 적합한 이모티콘을 개발하기 위해 간사이 공학의 방법을 이용하여 이모티콘을 제작하였다. 우선 여러 문헌을 통하여 도출된 디자인 가이드 라인에 따라 이모티콘 프로토타입을 개발하였다. 이후, 설문조사를 실시하고 요소 분석에 의한 분석결과를 기반으로 각기 성별에 따라 다르게 도출된 디자인 가이드라인을 프로토타입에 반영하여, 성별을 고려한 이모티콘을 개발하였다. 이렇게 개발된 총 3종류의 이모티콘에 대해서 감정표현도 대한 설문조사를 실시하였다. 일부 이모티콘에서는 연구자의 의도와 같게 성별에 적합한 이모티콘이 설계된 것으로 나타났으나, 다수의 이모티콘에 있어서는 성별과 제작된 이모티콘간의 일관성 있는 특징을 찾기 어려웠다. 각 이모티콘의 상세 분석결과 이러한 결과가 발생한 주요한 원인 중의 하나로 디자인 가이드 라인의 상세함이 부족했다고 판단되며, 이 연구 결과는 향후 남녀 사용자의 감정 표현에 적합한 캐릭터형 이모티콘의 개발 및 활용에 대한 기초자료로 활용될 수 있을 것으로 기대된다.
