Objectives: The objective of this study was to evaluate the thermic effects, the macronutrient oxidation rates and the satiety of medium-chain triglycerides (MCT). Methods: The thermic effects of two meals containing MCT or long-chain triglycerides (LCT) were compared in ten healthy men (mean age $24.4{\pm}2.9years$). Energy content of the meal was 30% of resting metabolic rate of each subject. Metabolic rate and macronutrient oxidation rate were measured before the meals and for 6 hours after the meals by indirect calorimetry. Satiety was estimated by using visual analogue scales (VAS) at 8 times (before the meal and for 6 hours after meal). Results: Total thermic effect of MCT meal (42.8 kcal, 8.0% of energy intake) was significantly higher than that (26.8 kcal, 5.1% of energy intake) of the LCT meal. Mean postprandial oxygen consumption was also significantly different between the two types of meals (MCT meal: $0.29{\pm}0.35L/min$, LCT meal: $0.28{\pm}0.27L/min$). There were no significant differences in total postprandial carbohydrate and fat oxidation rates between the two meals. However, from 30 to 120 minutes after consumption of meals, the fat oxidation rate of MCT meal was significantly higher than that of the LCT meal. Comparison of satiety values (hunger, fullness and appetite) between the two meals showed that MCT meal maintained satiety for a longer time than the LCT meal. Conclusions: This study showed the possibility that long-term substitution of MCT for LCT would produce weight loss if energy intake remained constant.

무선 센서 네트워크에서 다중접근제어(Medium Access Control: MAC) 프로토콜은 센서 노드들이 필요할 때만 on 상태에 머물게 함으로 에너지를 효율적으로 사용하도록 하게한다. 본 논문에서는 에너지 수확 무선 센서 네트워크에서 우선순위에 기반을 둔 에너지 효율적인 MAC 프로토콜(EEPB-MAC)을 제안한다. 제안된 EEPB-MAC은 기존의 IEEE 802.15.4의 비콘 프레임에 우선순위 비트, 전송 노드 주소, NAV 값을 가지는 필드를 추가하여 이를 통하여 우선순위 데이터 전송을 지원한다. 데이터 전송을 원하는 전송자로부터 비콘 프레임을 수신한 수신 노드는 수신된 비콘 프레임의 우선순위 비트에 기반으로 데이터를 전송할 전송자를 선택한다. 데이터의 특성에 따라 우선순위 전송을 지원할 뿐 만 아니라, 수신 노드의 잔여 에너지 레벨에 따라 전송 주기를 조절하는 등 데이터 전송에 참여하는 노드에서의 에너지 소모를 줄인다. EEPB-MAC 프로토콜은 기존에 제안된 다른 프로토콜에 비해 우선순위가 높은 데이터에 대한 전송지연을 줄이며, 각 노드에서의 에너지 소모를 개선시켰다.

The aim of the research study is to carve sustainable business strategies for the fashion communities in Ethiopia and Ukraine which are suffering today due to ever-increasing share of fast fashion consumerism. Fashion houses and international brands propagandize sustainability and consumption for better consumer base, where as originally sustainable local-based craftsmen still stay in the shade. Four communities/local designers are selected from the countries through the method of purposive sampling. Qualitative analysis is the basis of the research as we performed personal interviews and in-depth analysis of the communities to diagnose the problems and subsequently devise the solutions. In this research, we have studied and analyzed the problems faced by hereditary communities and ethnic designers in small and medium scale enterprise sector from two emerging economies. After the grounding the difficulties faced we advised strategies for sustainable future growth to the companies. The current academic literature on small and medium scale enterprises highlights the problems and solutions for general industry sectors. This paper brings attention to fashion communities and designers who promote national heritage and are struggling to survive in emerging economies due to industrialization and globalization. Moreover the comparison of the two geographies is unique in nature.

In recent years, building energy has received much attention and there are many support system to reduce building energy consumption. In addition, It is clear that encouraging to energy efficiency investments can be beneficial to our society, because of the energy supply instability and higher energy price in Korea. Nevertheless, ESCO business, represent the existing building energy retrofit business, hardly has not expanded in Korea. besides, in the case of existing building, it is more difficult to achieve the energy retrofit measures than new building, due to the existing buildings have attributes such as a long life and a lots of energy factor, etc. Therefore, for activate ESCO business and expand ESCO bussiness target to small-to-medium building, it is needed to optimization of retrofitting methods for existing small-to medium buildings in Korea. this research was to derive energy retrofit methods through the energy audit and analysis performed for a small-to-medium building located in Suwon, Korea.

Purpose: Oral candidiasis is the most common fungal infection in the oral cavity which is usually diagnosed from clinical findings. A retrospective study was conducted to identify risk factors for oral candidiasis and to characterize the demographic and clinical features of affected patients. Methods: From January 1, 2019 to December 31, 2019, it consisted of 90 oral candidiasis patients diagnosed based on clinical finding and treated with antifungal drugs. As a retrospective study of those people, surveys were conducted on sex, age, systemic disease, a use of dentures, complaints of dry mouth, smoking and alcohol consumption, culture on potato dextrose agar (PDA) medium, culture on chromogenic agar (CA) medium and a duration of antifungal treatment. Results: Among 90 selected patients, the male and female ratio was 41:49. Overall, female had a higher infection rate than male in all age groups. In this study, oral candidiasis was not clearly susceptible to dry mouth, smoking or drinking, wearing dentures and association with systemic disease. Among 90 patients with oral candidiasis, 83 had colonies formed on PDA medium and 53 had colonies formed on CA medium. The duration of antifungal treatment was highest between 5 and 8 weeks. In addition, there was statistical significance between the culture results in CA medium and the duration of antifungal treatment. Conclusions: Generally, old age or infants, dry mouth, smoking, a use of dentures and endocrine abnormalities are risk factors to increase oral candidiasis; however, in this study, it was mainly found in the elderly aged 60 or older regardless of sex and the incidence of oral candidiasis was not obviously related with patients with dry mouth, smoking or drinking, denture wearers and endocrine abnormalities. Interestingly, when the fungi were cultured in CA medium, the duration of antifungal treatment was increased.

HRccine was administered subcutaneously for 4 weeks to rabbits at dose levels of 300, 60 and 12 times the expected clinical dose to evaluate the subacute toxicity. There were no effects in clinical signs, body weight changes, food consumption, water consumption, urinalysis and blood biochemistry in any animals tested. In hematological examinations, decrease of lymphocyte counts and increase of platelet counts were observed in the medium- and high-dose treated groups. Absolute weights of thymus were tending to decrease, but no pathological changes were observed in microscopic examinations. The no-effect dose in subacute toxicity study of rabbits was considered to be 300 times the expected clinical dose.

This paper presents the optimized design, fabrication and thermal characteristics of micro-heaters for thermal MEMS (micro elelctro mechanical system) applications usign SOI (Si-on-insulator) and trench structures. The micro-heater is based on a thermal measurement principle and contains for thermal isolation regions a 10㎛ thick Si membrane with oxide-filled trenches in the SOI membrane rim. The micro-heater was fabricated with Pt-RTD (resistance thermometer device) on the same substrate by suing MgO as medium layer. The thermal characteristics of the micro-heater wit the SOI membrane is 280$\^{C}$ at input power 0.9W; for the SOI membrane with 10 trenches, it is 580$\^{C}$ due to reduction of the external thermal loss. Therefore, the micro-heater with trenches in SOI membrane rim provides a powerful and versatile alternative technology for improving the performance of micro-thermal sensors and actuators.
