Purpose: The purpose of this study was to investigate end-of-life care preferences of employees working in a university hospital. Methods: Of 650 eligible employees that were approached, 607 employees (386 nurses, 93 physicians, and 128 general staff) completed the Korean version of Preferences for Care Near the End of Life (PCEOL-K). Results: Among 5 dimensions of the PECOL-K, "Pain" was the most preferred care dimension and "Decision making by health care professional" was the least preferred care dimension. The item that received the highest mean score was "I want to let nature guide my dying and I do not want my life to be artificially prolonged in any way", and the lowest item was "I want health care providers to make all decisions about my care". As preferred care near the end of life, nurses gave lower scores to the life sustaining treatment and decision making by health care profession than physicians and general staff. Compared to physicians and nurses, general staff preferred the decision making by health care professional and by family. Conclusion: The results show that adequate pain relief is the most preferred care at the end of life among hospital employees and non-medical personnel preferred decision making by others.

인터넷을 기반으로 하는 전자상거래 도입은 기존 업무흐름에 큰 변화를 가져오기 때문에 기업 측면에서는 혁신 차원으로 받아들여진다. 그러므로 전자상거래 도입을 고려할 때 철저한 준비와 검토가 없이는 효율성과 기대성 측면에서 문제가 발생하기 쉽다. 인터넷은 정보검색의 차원을 넘어서 각종 재화는 물론 은행, 증권, 교육, 게임 등 다양한 서비스의 거래에 이용되고 있으므로 필수적인 상거래 도구가 되고 있으며, 많은 거래가 전자상의 거래로 대체되고 있다. 이렇듯 인터넷 전자상거래가 차지하는 비중과 역할은 앞으로 더욱이 확대될 것으로 전망되며 보안 기술에 대한 관심이 증대되고 있다. 따라서 본 논문에서는 전자상거래에 따른 효과적인 전략의 활용과 더불어 인터넷 전자상거래 시장의 활성화를 유도할 수 있는 방안에 대한 고찰을 실증적 분석을 통한 설계 방법론을 통해 제시하고자 한다.

Land use types within a watershed closely are related with the water quality characteristics of receiving water bodies. Despite of a numerous studies suggesting a strong relationship between water quality and land use, there have been increasing concerns about the geographical variation and a lack of spatial integration in that relationship, which are essential to implementing these findings into land use planning and management. In the meantime, edges mediate the material flux between adjacent systems. This mediating effect of edges is strongly related to the complexity of their shapes. Land use activities within a watershed have a direct impact on the water quality of adjacent aquatic systems, and hydrological processes carry residuals from watershed into adjacent aquatic ecosystems through the edges. Therefore, the geometry of reservoirs theoretically affects the relationship between land uses in the watershed and the quality of receiving bodies of water. In this light, this study integrates the geo-spatial dimensions of land uses in the watershed using GIS and landscape indices in order to explore the relationship between land uses and water quality. Water quality characteristics, land uses and geometry of 133 randomly sampled reservoirs were correlated, based on buffer zones and types of reservoirs. The findings showed that land uses, particularly urban land uses, significantly affect water quality characteristics including BOD, COD, TN and TP, and geometry of reservoirs reduces the concentration of pollutant and nutrients in reservoirs. One of results indicates that the relationship between land use and water quality and effects of spatial dimension may vary with types of reservoirs and pollutants. These results suggest that lakeshore areas are important, particularly for TN reduction and call for a caution to land use activities nearby shoreline areas for sustaining better water quality.

As the imports of foreign agricultural products are liberalized and the consumption of agricultural products declines, abandoned rice paddy fields continues to rise. However, such abandoned rice paddy fields has not been precisely surveyed yet. In this backdrop, a necessity to develop technology to utilize such abandoned rice paddy fields has emerged. Utilization of abandoned rice paddy fields as wetlands may be a good example. This study aimed to survey the current status and characteristics of wetlands created within abandoned rice paddy fields by selecting abandoned rice paddy fields throughout the nation and conducting field surveys on the sites that had transformed into wetlands. The abandoned rice paddy fields almost transformed into wetland and the types of wetlands transformed from abandoned rice paddy fields were mainly Inland/Moutain/Depression/Abandoned rice paddy fields/Marsh/Phragmites communis community and Inland/Moutain/Depression/Abandoned rice paddy fields/Swamp/Salix koreensis community. Abandoned rice paddy fields that had transformed into wetlands was depending heavily on waterways for water supply than other reservoirs and lakes do. Abandoned rice paddy fields transformed into wetlands was most observed in mountainous area. Abandoned rice paddy fields are because agricultural land is no longer profitable due to international and social changes and is not cultivated as government policy. Wetland period and dimension originated from abandoned rice paddy fields are very various and its surrounding land its mostly forest and the next largest follow roads and rural community. The abandoned rice paddy fields transformed into wetlands is mostly deserted currently. Despite their value as wetlands, no restoration and utilization efforts are made in Korea today. Therefore, it is imperative to conduct a precise current status survey on these areas and introduce management and restoration plans at the government level in the case of important habitats.

Current evaluation practices for IT projects suffer from several problems, which include the difficulty of self-explanation for the evaluation results and the improperly scaled scoring system. This study aims to develop a methodology of opinion mining to extract key factors for the causal relationship analysis and to assess the feasibility of quantifying evaluation scores from text comments using opinion mining based on big data analysis. The research has been performed on the domain of publicly procured IT proposal evaluations, which are managed by the National Procurement Service. Around 10,000 sets of comments and evaluation scores have been gathered, most of which are in the form of digital data but some in paper documents. Thus, more refined form of text has been prepared using various tools. From them, keywords for factors and polarity indicators have been extracted, and experts on this domain have selected some of them as the key factors and indicators. Also, those keywords have been grouped into into dimensions. Causal relationship between keyword or dimension factors and evaluation scores were analyzed based on the two research models-a keyword-based model and a dimension-based model, using the correlation analysis and the regression analysis. The results show that keyword factors such as planning, strategy, technology and PM mostly affects the evaluation result and that the keywords are more appropriate forms of factors for causal relationship analysis than the dimensions. Also, it can be asserted from the analysis that evaluation scores can be composed or calculated from the unstructured text comments using opinion mining, when a comprehensive dictionary of polarity for Korean language can be provided. This study may contribute to the area of big data-based evaluation methodology and opinion mining for IT proposal evaluation, leading to a more reliable and effective IT proposal evaluation method.

To develop an blue tourism website(BTW) for electronic commerce(EC), information requirements of BTW are defined firstly. We defined information requirements of BTW from two aspects, i.e., front office and back office. Information requirements for front office were derived by consumer purchasing decision process. And information requirements for back office were derived by tourism value chain. Total 29 functions are identified as critical EC related functions of BTW. Among them, 25 functions were investigated into BTW. BTWs were searched by search engines - Yahoo and Empas - to Korean websites. There are 12 specialized BTWs, except one cyber museum website. For 12 websites, 25 functions were probed. By the results, in need recognition stage of blue tourism, only weather information was provided in most websites. In information search stage of blue tourism, package recommendation and various contents were provided in most websites. In consumption stage of blue tourism, traffic information were provided in most websites. And in after - sales service stage of blue tourism, bulletin board function was implemented in most websites. The rest of the functions were scarcely implemented. On the whole, it was concluded that most EC related functions of BTW in Korea were not implemented properly. To improve the status quo, it is expected in the dimension of individual website, that marketing planning, customized service, intelligent service, reinforcing purchasing assistance functions, customer relationship management, and escrow service etc. need to be implemented. And it is expected in the dimension of blue tourism industry, that standardizing product catalog, security assistance policy, information sharing by industrial database, finding referral model of BTW, elevating information mind, revising related laws etc. are needed.

The beauty is like the bubble of beer, and behavior scholars have been regarded as worthless to study. As a result, the aesthetic in construction projects has resulted in underestimation or neglect. The fundamental cause of this result is that it is not easy to estimate the value of the aesthetic. The hedonic calculus by Bentham has a possibility to valuating the intangible or invisible goods. In this context, this study proposes a method to valuate architectural aesthetic based on the hedonic calculus by Bentham. As a precondition for suggesting the valuation method, this study defined the architectural aesthetic as the value of attraction that affects the value of the built environment. As the concept of beauty that conforms to the architectural aesthetic, it has established the concept of beauty as 'the phenomenon of combining the foreground and background of Hartmann'. In addition, the scope of the value measurement is defined as 'built environment' so as to include not only the building but also the surrounding environment. We have reinterpreted the seven dimension of the hedonic calculus proposed by Bentham and systematized the method of valuation of the architectural esthetic based on the seven dimension. The result of this study is meaningful in that it presents a new perspective and approach to architectural aesthetic. And it will be used as grounds for valuation and analytical approach to architectural aesthetic and will be used as a basis for expanding the field of study from aesthetic to value.

심한 하악 전돌증이 있는 환자의 경우 교정치료나 악교정수술을 활용하여 치료를 시도할 수 있으나, 장기간의 교정치료 및 수술의 침습적인 거부감이 있는 환자에서 보철적으로만 개선해야 하는 상황이 존재할 수 있다. 골격성 III급 부정교합 환자는 전방유도가 없으며, 수직적인 저작 양식을 보여주기 때문에 이러한 측면을 고려하여 치료하는 것이 중요하다. 또한, 전치부의 반대교합을 개선하기 위한 방법으로 교합수직고경을 거상하는 술식을 선택하기 쉬운데, 이는 종종 불리한 결과를 야기할 수 있으므로 신중한 진단 및 치료계획의 수립이 필요하다. 본 증례에서는 하악 전돌 및 비대칭을 가진 환자에서 단계적인 치료과정을 통하여 기존의 교합수직고경을 그대로 유지하며 임플란트 및 자연치를 이용한 최종 고정성 보철 수복을 진행하였다. 이에 기능적이고 심미적으로 적절한 결과를 보여, 환자의 진단 및 치료 과정에 대해 보고하고자 한다.

In empirical studies on rural development projects, differentiation tends to be considered a strategy aimed at increasing the number of visitors. Rural development projects include the improvement of living environment, and the discussion about project goals and evaluation of project results are often focused on the aspect of rural tourism. Thus, subjective benefits of such projects for residents are omitted. This study examines the meaning of differentiation from the perspective of residents and explores the validity of the number of visitors and the possibility of reflecting residents' subjective score as evaluation indicators for a project. To achieve such an objective, this study uses survey data collected from 153 people in 38 comprehensive development projects in areas of Eup and Myeon, Korea. The results of this study show that differentiation is viewed as a by-product of positive improvement from a rural development project, from the perspective of residents. The effects of rural development are classified into two dimensions: socioeconomic effects and living environmental effects. Landscape improvement is included in the dimension of living environmental effects and an increase in the number of visitors is included in the dimension of socioeconomic effects. As such, they are confirmed to be the factors that determine the level of differentiation. For example, the increase in the number of visitors is confirmed to be a valid indicator of project success, in which two-dimensional characters are reflected. The level of differentiation evaluated by residents is a result of the workings of the above two factors. Unlike in previous studies, the possibility of evaluation based on the perception of residents is confirmed in the evaluation of results. When the level of differentiation is interpreted as the direct result of a project, the number of visitors has an impact on socioeconomic effects, and the project content of landscape improvement has an impact on living environmental effects. The goal of policy and residents is the same in terms of the effort residents may make in maximizing results of a project by themselves; thus, the government's goal is achieved even when a project is carried out under the autonomy of residents. Ultimately, the government should focus on providing conditions in which active citizen participation can not only occur but help to establish a policy direction, which subsequently strengthens the substantial rights of residents.
