The performance of a novel medical question-answering engine called CliniCluster and existing search engines, such as CQA-1.0, Google, and Google Scholar, was evaluated using known-item searching. Known-item searching is a document that has been critically appraised to be highly relevant to a therapy question. Results show that, using CliniCluster, known-items were retrieved on average at rank 2 ($MRR@10{\approx}0.50$), and most of the known-items could be identified from the top-10 document lists. In response to ill-defined questions, the known-items were ranked lower by CliniCluster and CQA-1.0, whereas for Google and Google Scholar, significant difference in ranking was not found between well- and ill-defined questions. Less than 40% of the known-items could be identified from the top-10 documents retrieved by CQA-1.0, Google, and Google Scholar. An analysis of the top-ranked documents by strength of evidence revealed that CliniCluster outperformed other search engines by providing a higher number of recent publications with the highest study design. In conclusion, the overall results support the use of CliniCluster in answering therapy questions by ranking highly relevant documents in the top positions of the search results.

First aim of this study is to investigate consumer's actual value for environment related performance of house by using three different method, Ranking, Analytical Hierarchy Process (AHP) and Conjoint Analysis method. Second aim is to estimate consumers' monetary value about environment related factor through Marginal Willing to Pay(MWTP), and third aim is to find out the difference of values between the groups classified according to respondents' characteristics. A questionnaire survey was carried out in Seoul in order to clarify the preference and monetary value of four selected attributes. They are environmental performance, residents' health, home automation and increase of floor area. As a result, people showed high values in the order of health, environmental consideration, increase of floor area and home automation. Moreover, it was found out that MWTP for environmental performance and health are higher than market price. In addition, the group of high age and group of female showed high values for the reduction of $CO_2$ emission

This study was conducted to investigate the influence of different nutrient databases in estimating nutrient intake. A nutrient survey with Food Frequency Questionnaire containing 65 food items was conducted with 2,426 subjects over 30 years of age living in Yeonchon-gun, Kyungki province. The nutrient intakes were first estimated by using one (A) nutrient database which was based on the Korean Food Composition Table, 4th edition. With the other (B) nutrient database which was based on the Korean RDA(Recommended Dietary Allowances) 6th edition, it was reestimated and two resu1ts were compared. For most nutrients except carbohydrate, calcium, vitamin C and $eta$-carotene, mean nutrient intake level estimated from database B was significantly higher than that from database A(p<0.05). Mean intake level of most nutrients from two databases were significantly correlated by Pearson's correlation coefficients(p<0.001). Results from the ranking of nutrient intake levels of the subjects by two databases were highly correlated ( P >0.9, p<0.001). Weighted kappa values representing measures of agreement ranged from 0.55 databases ranged from 45% for vitamin C to 96% for carbohydrate. This result implies that different nutrient database may produce substantial differences in estimating the absolute nutrient intake but may not be crucial in ranking or classifying individuals with regard to specific nutrient intake.

Behaviour of 7 horned Japanese Black Cattle (3-9 years old) kept in a $450m^2$ dry-lot under loose housing condition was observed in the daytime (0930-1730 h) during 3 consecutive days. Eating and lying behaviour of cattle and the positions of all animals when lying together were recorded at 10-min intervals. Agonistic encounters and social licking interactions in the herd were also recorded. The cattle established a social hierarchy which was near linear. An irregularity in the diurnal rhythm of lying behaviour was found on the 3rd day, which appeared to be caused by oestrus behaviour of a herdmate. Eating frequency showed greater variation among individuals than lying frequency, and the most dominant animal ate most frequently in the herd. The spatial pattern of the herd when lying indicated a relatively loose dispersion in the lot. Higher ranking cattle tended to lie down more frequently near the hay rack in the lot, so that lower ranking animals had more difficult access to feed. Cattle with more social licking interactions had a tendency to lie down near each other irrespective of proximity of social order, therefore it was suggested that social preference among particular individuals occurred in the herd.

우리나라에서 에너지정책은 다양한 에너지 관련 계획들을 통해 구체화된다. 그런데 최근 비전으로서의 성격이 강한 상위계획에서 설정되는 부문별 목표가 지속적으로 상향 조정됨에 따라 상위계획과의 정합성을 유지해야 할 필요가 있는 (실행계획으로서의) 하위계획 수립에서 왜곡이 발생하고 있다. 이와 더불어 개별 하위계획 자체도 미래의 불확실성에 대응하여 계획의 유연성을 확보하는 측면에서 한계를 보이고 있다. 이러한 문제들은 잠재적으로 막대한 사회적 비용을 초래할 위험을 내포하고 있다. 이에 본 논문은 우리나라 에너지 계획의 수립 집행과 관련한 개선방안의 논의에 실증적인 근거를 제시하기 위해 실행계획 가운데 가장 중요하게 인식되고 있는 전력수급기본계획을 주된 분석대상으로 삼아, 전력수급기본계획 자체의 문제, 전력수급기본계획과 상위계획 간 정합성을 유지하는 과정에서 발생할 수 있는 문제를 논리적으로 설명하고, 현실적인 상황을 가정하여 그러한 문제들이 초래할 수 있는 사회적 비용의 규모를 추정하였다. 분석 결과, 전력수급기본계획 수립 시 최대전력이 실적치보다 7%(15%) 적게 추정되는 경우 2020년 기준으로 연간 발전비용이 약 2,860억원(1조 2,160억원) 증가하며, 이러한 사회적 비용은 상위계획인 국가에너지기본계획에서 설정한 미래 전력수요 목표치에 맞추어 전력수급기본계획이 수립 집행되는 경우에도 유사하게 발생함을 보였다. 또한 상위계획인 온실가스 감축 마스터플랜에서 전력부문에 부과하는 감축목표량이 과도하게 설정되어 탄소배출비용이 0일 경우의 적정 전원구성에서 발생하는 온실가스 배출량의 5%를 추가 감축해야 하는 경우에도 연간 발전비용은 2020년 기준으로 약 9,150억원 증가한다. 반면, 우리나라의 경우 전원별 경제성에 큰 차이가 존재하는 특성으로 인해 전력수급기본계획 수립 시 미래 $CO_2$ 가격의 불확실성이 초래하는 잠재적인 사회적 비용의 크기는 매우 작은 수준으로 분석되었다.

The grid cell analysis is used to select good sites as habitats at the region. The northern area of Yeongjong Island, Incheon has been disturbing by habitat loss due to human activities such as residential development, deforestation. In order to determine significant places as bird habitats and to select conservation areas at this island, the study area was divided into 70 grid cells($500{\times}500m$ each grid) and then each grid was ranked by spatial analysis using the species diversity index. Fieldwork was carried out in Spring and Autumn of 2010. To examine grid cells which were ranked high in both seasons in common, we used the average ranking value, combined data from two seasons. This area consists of mainly agricultural areas and forests(more than 68%) among eight habitat types: the agricultural land, forest, coast, lake, meadow, stream, city and other things. A total of 110 species was recorded: 4,183 birds of 102 species in Spring and 3,326 birds of 58 species in Autumn. In other words, the number of individuals and species was higher in Spring than in Autumn. Species diversity index presented the highest value at M8 grid cell in Spring(3.380) and at A4 gird cell in Autumn(2.736). In 18 of 22 grid cells where the average ranking value was higher than 3, the forest was distributed and in 4 grid cells, the coast and wetland were widely distributed, in which theses were located apart from human-associated disturbances such as construction works for a leisure complex. Our results present a new estimate method not only to minimize loss of bird habitats but also to conserve important habitats when the large-scale development takes place at particular region.
