When planning and promoting apartment house development project, it is very important to carry on profitability in planning stage through realistic evaluation and analysis about distributability. Especially, the analysis about project feasibility through forecasting the early distribute rate is crucial stage because it could evaluate overall expecting benefit and feasibility of the project. However, researches and studies related with forecasting profitability and distributabilty of construction development project are insufficient. Also there is a big gap of the standard for evaluating early distribute rate between government and individual corporations. So it is necessary to study about the evaluating early distribute rate. In this point, this study aims to present effective evaluating standard(criteria) which is for forecasting profitability and distribute rate through analyzing various factors and weight of apartment house development projects. This study compared and analyzed examples of the real initial rate of private apartment sale based on the government estimated standard. Among estimated index, omitted items and factors to be additionally considered are combined as 33 detail appraisal contents of 4 parts 9 items by allotting them based on the data about priority of all considered factors.

The purpose of this study is to predict future of wage-peak system by using text mining, futures wheel and polarity voting (+, -) techniques after reviewing a variety of documents. For this study, we collected articles, news articles, SNS(Twitter, Blog), research report documents. Above all, we extracted keywords for main subject words by utilizing text mining techniques. Next, we drew a final conclusion about future of wage-peak system by using futures wheel and polarity voting techniques. The result showed that future of wage peak system is positive. Two of five main topics were negatively predicted (favor/oppose of wage-peak system, solving task of wage-peak system), however, three of five main topics were positively predicted (background of wage-peak system, purpose/reason of wage-peak system, alternative wage-peak system). Therefore, because three of the five main topics were positively predicted, the future for wage-peak system is positive.

Purpose : To outline the aspects of extubation by birth weight and find the predictors for success/failure at the first extubation in extremely low birth weight infants. Methods : One hundred thirteen extremely low birth weight infants(<1,000 g) who were admitted to NICU at Samsung Seoul Hospital between Jan. 2000 and Jun. 2004 were enrolled. Clinical characteristics that are thought to be related with extubation success or failure were compared with the success and the failure of the first extubation. Results : As the birth weight decreased, extubation success day was significantly delayed : $16{\pm}3day(d)$ in 900-999 g; $20{\pm}3d$ in 800-899 g; $35{\pm}4d$ in 700-799 g; $37{\pm}9d$ in 600-699 g; $49{\pm}12d$ in ${\leq}599g$. 25 out of 113 infants(22%) failed the first extubation. Preterm premature rupture of membrane was associated with extubation success, and air leak was associated with extubation failure, with a borderline significance. Postnatal and corrected age and body weight at the first extubation, nutritional status, and ventilator settings were not associated with extubation success or failure. Extubation success day was significantly delayed, and the incidence of late-onset sepsis and mortality was significant higher in the failure of the first extubation. Conclusion : We could not find significant predictors for success/failure at the first extubation. The failure of the first extubation had an increased risk of late-onset sepsis and death. Further studies are needed to find the predictors for extubation success/failure.

The present study aims to analyze kickers' strategic actions for finishing in penalty shoot-outs among youth soccer players ultimately to increase success rates of shoot-outs and to score a victory. Subjects were experienced 271 soccer players attending high schools located around the capital area. To determine any difference in strategic actions for finishing in penalty shoot-outs among the subjects, frequency analysis or chi-square was used for the analysis. The analysis found the following points: First, the success or failure rates of kickers in penalty shoot-outs were found to depend on subjects' experiences as soccer players. Second, in terms of kickers' shooting qualities, they were found to shoot on goal regardless of shooting positions. Third, an important factor to enhance the shoot-outs probability was found to be a strategic action through the eyes. Fourth, in view of the strategic actions prior to kickers' shooting, goalies were found to check out kickers' positions first and estimate the directions and qualities of shooting via kickers' body actions and eye lines.

This study explored the elements, types, and determining factors of successful aging for the Korean elderly. In order to examine the expectations of the Korean elderly, a sample of 377 elderly aged 65 and over living in Seoul and Kyunggi areas was selected and interviewed. The elements of successful aging that the Korean elderly pointed out in the interviews were: 'peaceful and comfortable life', 'self-maintenance,' 'secure social support,' and 'ostentation.' The expected elements of successful aging were further classified into three types of successful aging: 'idealized expectation.' 'self-centered expectation,' 'balanced self-other expectation.' The elderly groups sorted by the types exhibited significant differences in terms of demographic characteristics, self-evaluated economic status, and self-evaluated health status. The variables that affected the expectations were age, level of education, marital status, gender, and self-evaluated health condition. However, further analysis revealed that the factors that affected the expectation for successful aging were different for male and female elderly. The results suggest that the successful aging of Korean elderly should be understood in the context of Korean society and culture. The results could be used to better understand varied and unique life of Korean elderly, as well as in establishing a basis of intervention that meets the specific demands of the Korean elderly.

미해양대기청 기후예측센터(Climate Prediction Center, NOAA)에서 제공하고 있는 기후지수(climate indices)를 예측인자로 하고 금강유역의 5~6월의 강우량을 예측대상으로 하는 원격상관기반 통계모형을 구축하였다. 1988년부터 2017년까지의 30년 자료에 대해 예측인자와 예측대상간의 시간지연상관분석을 수행한 결과 NAO(North Atlantic Oscillation), EP/NP(East Pacific/North Pacific Oscillation), EA(East Atlantic Pattern), WP(Western Pacific Index) 등과 상관성이 높은 것으로 분석되었으며, 이러한 시간지연 기후지수를 이용하여 4개월전에 5,6월 강수량을 예측할 수 있는 다중회귀모형을 개발하였다. 관측 강우량 아노말리가 큰 경우에는 다소 과소 예측되고, 아노말리가 작은 경우에는 다소 과다 예측되는 경향을 보였지만 관측 강우량과 예측 강우량간의 상관계수가 0.75로서 비교적 우수한 예측 결과를 나타내었다. 5~6월 강우량 아노말리의 3분위 예측성을 평가한 결과 평년이상 적중률은 77.8%, 평년수준은 81.8%로서 예측 성공률이 높았으며, 5, 6월 누적강우량이 매우 작았던 92년과 95년을 제외하고는 강우량이 적은 해에도 예측성이 우수하여 평년이하 적중률이 70.0%를 나타내었다. 따라서 본 개발모형은 최소 4개월 이전 선행시간을 가지고 늦봄, 초여름강우량을 예측할 수 있는 저비용의 가뭄 예측 도구로 유용하게 활용될 수 있을 것이다.

인터넷 사용자의 증가와 함께 전자상거래가 활성화되면서 그 성공요인을 규명하고자 하는 노력은 계속 되고 있다. 특히 정보기술의 발달로 서비스의 온라인 거래가 가능해지고 있고 그 비중 또한 증대되고 있으나 아직까지 온라인에서의 서비스에만 초점을 맞춘 연구는 제한적이다. 따라서 본 연구는 전자상거래에서 거래되는 서비스에 대한 고객의 인식을 바탕으로 서비스의 오프라인 대비 온라인 선호에 영향을 미치는 요인들을 규명하고자 한다. 이를 위해 현재 국내 포탈에서 제공되는 서비스를 대상으로 고객설문을 수행하였으며 수집된 자료를 활용하여 온라인 선호에 대한 로지스틱 회귀분석을 실시하였다. 제안된 모형은 순수 오프라인에서 제공되는 서비스의 일부를 온라인 서비스로 전환하고자 할 때 고려해야 하는 요소들이 무엇이며 그 성공가능성을 예측할 수 있도록 도와줄 것으로 기대된다.

현재 자율운항선박의 성공적 달성을 위해 다양한 연구개발이 진행 중이며 이와 관련하여 자율운항선박의 안전항해 지원을 위해 자율운항 지원 서비스와 해양사고 대응 서비스가 개발되고 있다. 자율운항 지원 서비스는 전자해도표시시스템(ECDIS, Electronic Chart Display and Information System)에서 수립하는 항로 계획 정보를 육상 운항조정상황실에 전송하여 충돌 위험 예측 후 유용한 정보를 자율운항선박에게 제공하는 서비스이다. 이 서비스를 통해 타 선박과 자율운항선박간의 조우 지점과 타 선박의 사전 변침정보를 미리 알 수 있기 때문에 충돌 예측 정보로써 활용할 수 있다. 해양사고 대응 서비스는 현재 사람에 의존적인 해양사고 상황인식 및 해양사고 대응기관에 전파하는 것을 자동으로 상황을 인식하고 사고 대응하는 서비스이다. 이 서비스를 통해 사고 단계별 유용한 정보를 사고선박 및 주변 해양사고 대응기관에 정보를 제공함으로써 추가적인 해양사고 방지와 즉각 대응이 가능하다. 본 연구에서는 2가지 서비스를 성공적으로 제공하기 위해 시스템의 요구사항을 분석하고 시스템 아키텍처를 설계하였다.
