조사비용과 시간과 같은 현실적인 제약하에서 관측단위 (observation unit)의 집합인 집락(cluster)율 추출하는 집락추출법은 대부분의 대형조사(large scale survey) 에서 흔히 사용된다. 특별히 집락내의 관측단위가 매우 유사한 경우, 집락 내의 모든 관측치를 조사하는 대신 일부를 추출하여 조사하는 이단계 집락 추출법이 선호된다. 이단계 집락추출법의 적용시 집락인 1차추출단위 (Primary Sampling Unit; PSU)와 관측단위인 2차추출단위(Secondary Sampling Unit; SSU)의 표본수 결정은 주어진 비용과 표본으로부터 계산되어지는 통계량의 정도에 의존한다. 본 연구에서는 기존의 1차추출단위의 크기가 동일하다는 가정하에서 유도된 최적 PSU와 SSU 표본크기 산출과정을 일반화하여 1차추출단위의 크기가 같지 않을 경우의 최적 표본크기를 유도하고 그 결과를 제 4차 퇴원환자조사를 위한 표본추출 방안에 적용하여 기존방법과 비교하였으며 이를 바탕으로 제 7차 퇴원환자조사를 위한 표본크기를 제안하였다.

In researches done previously, the characteristics of the Hyangyak medicine in the early period of Chosun shown in "HyangyakBoncho(鄕藥本草)" in Vol. 76-85 of "Hyangyakjipseongbang(鄕藥集成方)" and "Sanghan section(傷寒門)" in Vol. 5-8 of "Hyangyakjipseongbang(鄕藥集成方)" was investigated. "Cough section(咳嗽門)" in "Various Diseases volume" of "Dongeuibogam(東醫寶鑑 雜病篇)" Vol. 5 and "Various Coughs section(諸咳門)" of "Hyangyakjipseongbang(鄕藥集成方)" Vol 24-25 which is a paragraph related to "Sanghan section(傷寒門)" was compared. The variety of the Hyangyak, processing methods and forms of the Hyangyak were shown by comparing each oriental medical botany(本草) used for treating cough(咳嗽) in "Dongeuibogam(東醫寶鑑)". Subsequently, the difference between each structure and medical theory was speculated. The facts revealed in this research is as follows. First, [Various Coughs section(諸咳門)] of "Hyangyakjipseongbang(鄕藥集成方)" uses only the Hyangyak, and no foreign medicines were used for treating cough(咳嗽) in "Dongeuibogam(東醫寶鑑)". Second, in [Various Coughs section(諸咳門)] of "Hyangyakjipseongbang(鄕藥集成方)", medicines related to diet and medicines taken raw were widely used, and various forms of medicine such as extracts, plasters, and gruels were used. Third, like other medical books in earlier periods, [Various Coughs section(諸咳門)] of "Hyangyakjipseongbang(鄕藥集成方)" describes the medical theory with conciseness, and keeps the structure of symptom classification focused on treatment and prescription. Fourth, as [Hyangyakboncho(鄕藥本草)] extensively uses the knowledge of oriental medical botany(本草) from two of Four Masters of GeumWon(金 元); JangWonSo(張元素) and LeeDongWon(李東垣), "Various Coughs section(諸咳門)" of "Hyangyakjipseongbang(鄕藥集成方)" quotes the books of JuDanGae but does not adopt the theory and prescriptions of 'replenishing yin and downbearing fire (滋陰降火)'. To find a more descriptive picture of the Hyangyak medicine for the treatment of 'cough(咳嗽)', a comparatitive study between the books written in the same period -"Euibangyuchui(醫方類聚)" and books compilated in China should be done, and there should be more profound researches done on individual medicines and prescriptions.

This study aimed to investigate the effect of acorn powder and starch on the blood parameters of mice fed a high-fat diet. The moisture, crude ash, crude protein, and crude fat contents of acorns were $37.99{\pm}0.37%$, $1.61{\pm}0.06%$, $4.36{\pm}0.18%$ and $3.22{\pm}0.15%$, respectively. Acorn powder and starch contains antioxidant minerals such as selenium and zinc. The iron content was significantly higher in acorn powder than in acorn starch (p<0.05). The total cholesterol concentration was $148.50{\pm}29.72mg/dL$ in the high-fat starch diet (HFS) group, while in the high-fat diet (HF) group it was $201.50{\pm}39.15mg/dL$ (p<0.05). Serum LDL-cholesterol concentrations were significantly lower in the HFS group ($50.50{\pm}10.79mg/dL$) than in the HF group ($62.00{\pm}20.85mg/dL$; p<0.05). The serum $IL-1{\beta}$ levels in mice were not significantly different between the groups. IL-10 levels were higher in the HFP group than other groups. There is a need for strong recognition that acorns are good ingredients worldwide. It is required to develop various products using acorn powder and starch powder. There is also a need for a strategy to globalize food using acorns.

This study investigated the quality, sensory characteristics and commercial potential of a rice snack prepared with dried oyster. Mild and spicy versions of the snack were produced using an oil coating and a mixed seasoning powder coating, respectively. The approximate compositions of the mild snack and spicy snack were 5.13% and 4.78% moisture, 8.92% and 8.94% crude proteins, 17.58% and 20.35% crude lipids, 1.88% and 1.87% ash, and 2% and 1.8% salt, with water activity values of 0.20 and 0.18 and a pH of 6.11 and 6.10, respectively. The color of the mild snack was lighter with more yellow and less red compared with the spicy snack. Thiobarbituric acid levels increased slightly, and hardness decreased slightly during storage at $27{\pm}2^{\circ}C$. The sensory score of the spicy snack was slightly higher than that of the mild snack. These results suggest that the spicy snack might have more commercial potential than that of the mild snack according to its higher sensory test score.

As the increase in quantity of apartments has been stable, consumers' needs in housing quality become more diverse. According to the changes in the tendency of residents, construction companies has developed brands of apartment buildings with the concepts of LOHAS, well-being, ergonomics, ubiquitous. However, these trends has been focusing on the Capital area, and becoming fixed and typical in the way of delux quality, large-sized houses and a healthful residence. For that reason, this research is about survey on the needs of the local apartment residents, especially in Daegu. This analysis of their preferences will furnish basic data and offer possible interior plans to building companies making inroads into the Daegu apartment market. This research is based on the questionnaire forms which had been collected for two months(in Aug.-Oct.) of 2005 in Daegu and the amount of the samples is 135. All of them are the residents of the apartments where they moved in after 2000. The contents of this research include the evaluation of plane composition and practicality, interior finishing and design, and spaces for items. The results of this research show that the interior design and finishing materials of apartments in Daegu should be improved and the drainage and uncleanness of bathroom also need to be considered, much like the results of Seoul area. However, regarding the higher age range and life stage, the bedroom 2 needs to be planned for a study and the design of livingroom is prefered to be widely open. Besides, comparing with those in Seoul, the residents in Daegu demand that spaces for things (especially those in secondary kitchen and dress room) be more organized and convenient.

진동해석과 기술에 있어서 실험과 해석분야 모두 다 같이 발전한 것은 사실이지만, 실험해석법은 유한요소법과 같은 이론해석법만큼 발달한 것이라 할 수 없을 것이다. 그 이유 중에 하나로 비선형 방정식을 푸는데 있어 초기치의 선택에 따라 계산시간이 길어지고 해가 종종 발산하기도 하기 때문이다. 일반적으로 실험모드해석에 있어 방정식은 고유진동수와 감쇠비의 비선형 항과 등가강성의 선형 항으로 구성된다. 본 연구에서는 비선형 항을 먼저 구하고, 다음에 선형 항을 구하였다. 개발된 실험모드해석법(곡선맞춤법)을 선체상부구조 모델에 적용하여, 모드 특성치들을 계산하였다. 또한 개발된 프로그램은 그래픽기법을 적용하여 간단한 마우스 조작으로 채용 모드수와 감쇠비를 결정할 수 있도록 하였다.
