The purpose of this study is to develop effective destination management strategies for three typical tourist destinations in Kangwon province based on the importance-performance analysis. The results show that overall performance levels of 21 management attributes in three destinations is relatively low, compared to the importance levels of the attributes. 6 attributes place in Concentrate Here, 4 attributes in Possible Overkill, 6 attributes in Keep Up Good Work, and 5 attributes in Low Priority. There is no significant difference in the importance level among three destinations, while performance levels are the lowest at Naksan & Kyungpo beaches, and highest at Ganhyun area. Findings of the survey expect to be used as fundamentals in management policy making process for each destinations.

우리나라 국립공원은 좁은 공원면적에 비해 높은 이용도와 인력 및 재원의 부족, 공원별로 특화된 계획 부재로 인해 관리에 어려움을 겪고 있다. 여기에 주5일 근무제 가 확대시행 된다면 국립공원 방문수요가 증가할 것으로 예상되고 있어, 이에 대비한 관리전략의 수립이 절실하다. 본 연구는 주5일 근무제 정착에 대비해, 국립공원 이용자들의 선택행동에 영향을 주는 속성별 수준의 종류와 영향력 정도를 파악하고 관리의 우선순위를 결정해, 자인자원의 보전과 이용자 만족이라는 목적을 달성할 수 있는 방안을 제시하고자 수행하였다. 5대 대도시에 거주하는 1,000명을 대상으로 자료를 수집하여 conjoint choice model로 분석한 결과, "휴무일수의 증가"는 국립공원 방문의도와 정(+)의 방향을 보이 는 것으로 나타났다. 속성별로는 "환경교육" 과 "연계 관광"은 모든 수준에서, "공원 내 숙박시설”과 "관광여건", "비용"의 일부 수준에서 '현재상태' 보다 선호가 증가했지만 "자연보호"는 선호 증가가 없었다.

The purpose of this research is to identify satisfaction levels of the arboretum which will be provided in the Multifunctional Administrative City and to estimate the economic value of using choice experiments. The attributes were "Preservation", "Education", "Recreation", "Facility", "Accessibility" and the entrance fee. The main effects model was utilized to construct hypothetical alternatives. Calibration of the conjoint choice model revealed that 'wetlands' and 'forest trails' in "Preservation" and the "Recreation", respectively, were significant variables. This result indicates that respondents are willing to pay more for these if they are provided in the arboretum. Also, 'variety seeking' tendency, age, and income level positively influenced the provision of the arboretum. Involvement in preservation of natural environment, however, had a negative influence on the establishment of the arboretum. Because this study is the first attempt to estimate the economic valuation of an urban arboretum using choice experiment, there are several suggestions for future research in terms of determining the base level and inclusion of salient attribute levels.

Building information modeling (BIM)-based construction projects have increased and become more varied, and as such the management of BIM-based facility information is also increasingly important for facility maintenance. Information management, and specifically product data mapping, however, has some problems in the area of manual data entry and does not adequately consider the exchange requirements of facility maintenance. Therefore, it is necessary to introduce a method to improve the management of composite object information for BIM-based facility maintenance so that it can handle construction operation building information exchange (COBie) data for a composite object. Therefore, we present a method to map COBie data to related materials of a composite object. This research contributes to increasing the efficiency and accuracy of the required information mapping between a building model and product data using a BIM library through optimal BIM data adoption. Moreover, it allows for the creation and management of specific product data at the design development phase.

This study is an online survey for consumers in the metropolitan areas of Japan and Korea, which are advanced countries in Asia, and the maturity of the automobile market. The purpose of this study is to compare the results of Korea and Japan. As a result of this study, we analyzed the differences between the consumer characteristics and the optional attribute factors of low-carbon automobiles of Korea. There was a difference. It was found that the factors of low carbon car selection attribute differed with age, and that stability was more important when selecting low carbon car as income level increased. In Japan, there were no differences in the selection attribute factors of low carbon cars by gender, age and income. In addition, there is no difference in the relationship between the future purchase timings of low-carbon car types in both Korea and Japan. Implications of this study Korea has a meaningful result that Korea tends to select low-carbon automobiles with an emphasis on economic aspects and ages, and that safety tends to emphasize safety of low-carbon automobiles according to income levels. In the case of low carbon car, there was a tendency to select a low carbon car without any difference in consumer characteristics. The relationship between the expected purchase time according to the type of low carbon car and the Korean car show that the preferred car within the next 10 years among the low carbon car types is electric car and Japan prefers hybrid car.

2011년 후쿠시마 원자력발전소 사고 이후, 발전원의 위험사고비용 및 환경피해비용에 대한 관심이 대두되고 있다. 전력은 생산과정 뿐만 아니라 발전소 건설, 발전소 운영, 송 배전을 통한 전력 공급, 폐기물처리 등의 각 과정에서 다양한 환경비용을 야기하고 있다. 따라서 발전원의 환경영향을 수용자적 입장에서의 평가할 필요가 있다. 본 연구에서는 컨조인트 분석법의 일종인 선택실험법을 적용하여 발전에 따른 환경영향 속성들에 대해 평가한 후, 발전원별로 상이한 속성 값에 속 성별 추정치를 반영하여 발전원별 환경비용을 수용자적 입장에서 추정하였다. 발전원부문이 환경에 미치는 영향에 대한 속성을 온실가스 배출, 건강피해, 지역피해, 온배수 배출로 선정하였고, 제시금액은 비교 대상 발전원들의 전력거래 단가 및 가구당 지출하는 월평균 전기요금수준을 기준으로하여 35,000원에서 75,000원까지의 총 다섯 가지 속성수준으로 구분하였다. 다항로짓모형을 적용하여 발전원별 각 환경영향에 대한 속성별 한계지불의사액 추정하고, 발전원간의 환경비용을 산정하였다. kWh 당 수력발전(0원/kWh) 대비 타 발전원의 추가 환경비용은 26원/kWh­832원/Wh로 환경적 영향 측면에서 국민수용성이 가장 높게 나타났다.

The school foodservice was quantitatively extended by policy of government all the while. There was carried out the survey of customer satisfaction about school foodservice by the ministry of education, science, and technology since 2006 years. Therefore, the purpose of this study was to grasp an improvement of the scores of school foodservice' quality attributes and satisfaction as compared with the preceding year by respondents and school type (elementary school, middle school, and high school). An annual survey was practiced to respondents (students, parents, and faculty) on september 2007 years and 2008 years in 16 cities and provinces. The statistics was analyzed to descriptive analysis and t-test for SPSS 12.0. The scores of school foodservice' quality attributes and overall customer satisfaction were almost increased to students, parents, and faculty and especially, big elevation in middle school. There was big increased the quality attributes such as 'providing information on foodservice', 'pleasant foodservice environment', 'kindness offered by employee' in elementary school, middle school, and high school to total respondents. An overall satisfaction in school foodservice was improved from 69.2 score to 71.9 score. On students, scores of overall satisfaction was increased from 72.9 to 74.0 as students of elementary school and from 61.5 to 65.8 as students of middle school (p < .001). Therefore, for improvement and development of school foodservice, there should be a necessary for an operator of school foodservice and an office of education to make an effort.
