  • 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.

  • In this study, a design of emoticons based on sex was studied through Kansai engineering method. First, we developed emoticon prototypes according to a design guideline derived from existing related literatures. Then, the design guidelines was updated from the survey results on the properties of emoticon, and the two sets of modified emoticons were developed from them. Another survey was executed to evaluate the degree of emotional expressions on the three types of emoticons developed in this way. A small number of emoticons were found to be designed fulling the researcher's intention. However, in many other emoticons, it was difficult to find a consistent characteristics. Even though it was observed through detailed analysis that one of the main causes of this result was lack of detail in the design guidelines, the results of this study are expected to be used as basic data for the development and application of character - type emoticons suitable for male and female users' emotional expressions in future researches.
