  • TPS(Triple Play Service)의 적용을 위한 유망기술로 PON(Passive Optical Network)기술이 있다. PON 기술의 가장 중요한 요소는 패킷의 처리량을 효율적으로 높일 수 있는 MAC(Multiple Access Control)기술이다. MAC 기술의 핵심은 DBA(Dynamic Bandwidth Algorithm)로 내부 환경을 고려하는 SR-DBA(Status Report DBA), 환경을 고려하지 않는 NSR-DBA(Non Status Report DBA)방식이 존재한다. 하지만 GPON의 DBA 알고리즘은 BPON의 알고리즘을 사용하여 성능이 떨어진다. 본 연구에서는 네트워크의 효율적이고 신속한 처리를 위한 BR(Borrow-Refund)-DBA 알고리즘을 개발하였다. 알고리즘의 성능평가를 위하여 처리량(Throughput), 공정성(Fairness), 큐 지연(Queue Delay) 항목에 대해 SR-DBA, NSR-DBA의 환경에 맞추어 평가하였다.

  • 본 연구는 노인의 우울, 영양상태 및 인지기능이 삶의 만족도에 미치는 영향을 파악하여 변수들 간의 관계와 효과를 규명하는 위해 이루어졌다. 자료는 한국보건사회연구원에서 시행한 2017년도 노인실태조사 자료를 사용하여 2차 자료분석을 실시하였다. 65세 이상의 노인 9089명을 대상으로 경로모형을 만들고 상관분석 및 경로분석을 통해 가설을 검증하였다. 그 결과, 우울, 영양상태, 인지기능 및 삶의 만족도는 모두 유의한 상관관계를 보였다. 영양상태에 영향을 주는 요소로서 우울(.46, p=.007)의 효과 크기가 유의하였으며 인지기능에 대해서도 우울(-.27, p=.014)의 효과 크기가 유의하였다. 영양상태(.08, p=.009)와 인지기능(-.03, p=.010)은 모두 삶의 만족도에 유의한 효과를 보였는데, 우울(.50, p=.012)은 영양상태와 인지기능을 매개로 하여 삶의 만족도에 영향을 주었다. 따라서 노인의 삶의 만족도를 증진시키기 위해서는 우울에 대한 중재 뿐 아니라 영양상태와 인지기능에 대한 간호 중재가 필요하다.

  • Thailand is becoming an aging society, this presenting as a serious problem situation especially regarding health. Chronic diseases found frequently in the elderly may be related to dietary intake and life style. Surin province has been reported as a risk area for liver fluke with a high incidence of cholangiocarcinma especially in the elderly. Therefore, this study aimed to determine the nutritional status and associated factors among elderly in Surin province, northeast of Thailand. A community-based cross-sectional study was conducted among 405 people aged 60 years and above, between September 2012 and July 2014. The participants were selected through a randomized systematic sampling method and completed a pre-designed questionnaire with general information, food recorded, weight, height, waist circumference, and behavior regarding to food consume related to liver fluke infection. The data were analyzed using descriptive statistics and Spearman's rank correlation coefficients. The majority of participants was female (63.5%), age between 60-70 years old (75.6%), with elementary school education (96.6%), living with their (78.9%), and having underlying diseases (38.3%). Carbohydrate (95.3%) was need to improve the consumption. The participants demonstrated under-nutrition (24.4%), over-nutrition (16.4%), and obesity (15.4%). Elderly had a waist circumference as the higher than normal level (34.0%). Gender, female, age 71-80 years old, elementary school and underlying diseases were significantly associated with poor nutritional status. The majority of them had a high knowledge (43.0%), moderate attitude (44.4%), and moderate practice (46.2%) regarding food consumption related to liver fluke infection. In conclusion, these findings data indicated that elderly age group often have an under- or over-nutritional status. Carbohydrate consumption needs to be improved. Some elderly show behavior regarding food consumption that is related to liver fluke infection hat needs to be improved, so that health education pertaining good nutrition is required.

  • The purpose of our study is to analyze the effect of socio-economic status on the diet pattern of Korean adults. Raw data from the fifth (2010-2012) Korea National Health and Nutrition Examination Survey (KNHANES) were used, and finally 11,700 adults were analyzed as subjects. Results in consideration of the socio-economic status of the subjects, a linear trend was observed in men in which the odds ratio of having lunch (p for trend=0.006) and dinner (p for trend=0.0317) decreased as the level of education went down. In diet frequency, a decreasing trend (p for trend=0.0328) was observed in which the odds ratio of having 3 meals a day reduced as the household income lowered. For women, a linear trend (p for trend=0.0012) was observed in which the frequency of dinner decreased as the level of education became lower. A falling trend in the rate of having 3 meals a day was also observed (p for trend=0.0135). Our study analyzed the characteristics of the diet patterns of individuals according to their socio-economic status with the purpose of suggesting guidelines for correcting. To prevent this, we will need education and awareness and public attention for the practice of correct eating habits.

  • In the recent defence industries, it is required to develop the small and low cost embedded systems for guided missiles. According to the characteristics of guided missiles, the mission is conducted with multiple phases, which include a squib activation phase. By considering the unexpected squib activation, the squib system should be disabled after the launch of a guided missile. Therefore, the squib system needs to include the functions of the safe ignition and status check. This paper presents the squib ignition and status check circuits design for the compact embedded systems in guided missiles. Validation results show that for the functions of the squib ignition and status check, the presented circuits design performs well. The designed circuits also were implemented with various electronic devices and validated by the ground and flight tests.
