  • BACKGROUND/OBJECTIVES: The fruit of Cydonia oblonga Miller (COM) is used traditionally in Mediterranean region medicine to prevent or treat obesity, but its mechanism of action is still unclear. Beyond a demonstrated anti-obesity effect, the fruit was tested for the mechanism of adipogenesis in 3T3-L1 preadipocytes. MATERIALS/METHODS: 3T3-L1 preadipocytes were cultured for 8 days with COM fruit extract (COME) at different concentrations (0-600 ㎍/mL) with adipocyte differentiation medium. The cell viability was measured using an MTT assay; triglyceride (TG) was stained with Oil Red O. The expression levels of the adipogenesis-related genes and protein expression were analyzed by reverse transcription polymerase chain reaction and Western blotting, respectively. RESULTS: COME inhibited intracellular TG accumulation during adipogenesis. A COME treatment in 3T3-L1 cells induced upregulation of the adenosine monophosphate-activated protein kinase (AMPK)α phosphorylation and downregulation of the adipogenic transcription factors, such as sterol regulatory element-binding protein 1c, peroxisome proliferator-activated receptor γ, and CCAAT/enhancer binding protein α. The COME treatment reduced the mRNA expression of fatty acyl synthetase, adenosine triphosphate-citrate lyase, adipocyte protein 2, and lipoprotein lipase. It increased the mRNA expression of hormone-sensitive lipase and carnitine palmitoyltransferase I in 3T3-L1 cells. CONCLUSIONS: COME inhibits adipogenesis via the AMPK signaling pathways. COME may be used to prevent and treat obesity.

  • Chicken production remains the foremost endeavor in the Nigerian livestock industry. However, disease incidence has been a major constraint on the growth of this subsector. This study assessed health management practices and disease incidence in smallholder chicken production enterprise in Southwest Nigeria using data from a farm survey of 240 farmers selected using a multistage sampling technique from 5 of 6 states in Southwest Nigeria. The study showed that vaccination was given by 96.8% of the famers, 97.8% dewormed their chickens, and 92.9% disinfected the coops against diseases. However, 37% of the farmers regularly consulted veterinarians, 25.7% consulted them during disease outbreaks, and 34.2% occasionally consulted veterinarians. Infectious bursal disease (IBD), coccidiosis, and chronic respiratory disease (CRD) were the major diseases reported by 17.1%, 12.9%, and 7.1% of the farmers, respectively. Mortality rate was 37.8%, although this varied with disease. However, there was a growth of 157.4% in stock size between the establishment of the farms and the survey period.

  • 혁신적인 경제에서 정책 인센티브와 정책방향의 개발은 항상 중요하다. 혁신정책은 특화산업의 시장구조를 선도하면서 산업의 역동성을 결정하기 때문이다. 본 연구는 대전지역의 무선통신산업의 변화를 이해하기 위해 산업융합의 발전을 탐색한다. 초기의 관심은 기업자체의 R&D센터였지만, 비즈니스 모델은 자체적인 상품의 연구개발보다 외부 수요에 대응하는 연구개발이 대부분이었다. 지역혁신을 위해서, 무선통신융합산업의 정책은 자체 제품개발패턴이 되어야 한다.

  • 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.

  • Background : Mutual understanding between North and South Korea is essential for the engagement of Inter-Korean exchange and cooperation. However, the two Koreas have been divided for 70 years where Korean evolved differently within the two countries. This created a gap in the most basic foundation for mutual understanding, language. Fostering exchange and cooperation in the traditional medicine field requires a higher understanding of the specialized traditional medicine terminologies. Objectives : The purpose of this study is to formulate a future management plan for the "Comparative Terminology of Korean Medicine in South and North Korea," providing a foundation for standardizing Korean medicine terminology of the two Koreas. Methods : The study collected case studies of Korean medicine terminology management and standardization from government and international organization websites and documents. It provided future terminology management strategies based on this data. Results : The project for the standardization of Korean medicine terminology between North and South Korea can be divided into 4 stages according to the level of exchange and cooperation. The first step is to "establish a foundation for terminology standardization." The second step is "term comparison." If the exchanges and cooperation between North and South Korea, the third step will be to promote the "terminology standardization" project through Inter-Korean dialogue. Finally, after incorporating discussion on terminology standardization, the Inter-Korean Medicine Terminology can be published. Conclusions : This requires a system to support and facilitate Inter-Korean medicine exchange and cooperation. It is important to provide a support system that can provide results in a timely fashion by training relevant experts, collecting data and information, communicating with experts in the industry, academia and research institutes. This system will be able to ensure the continuity of the terminology standardization project.

  • Taking sample processes from the combined heat and power plant in Busan Fashion Color Industry Complex, the characteristics and amounts of greenhouse gas (GHGs) emissions were analysed and calculated, respectively. Based on the results, environmental assessment was evaluated for recent 3 years. The amounts of GHG emissions from 2011 to 2013 were estimated at 182,750, 184,384 and 190,250 $Ton.CO_2eq/year$, respectively. GHG emissions from stationary combustion sources were found to be more than 99 % of the total emissions. Also, the overall eco-efficiency indicator for environmental assessment was more than 1, suggesting that these results would be beneficial for GHG emissions allowance allocations.
