  • The purpose of this study is to propose agenda concerning the direction of agricultural science convergence research and development (R&D) under the fourth industrial revolution. For this study, we apply the Analytic Hierarchy Process (AHP) targeted at experts in the fields of agricultural academia and research operating R&D currently. Results suggest the following agendas; first, human resource training toward future is more emphasized rather than fragmentary technology innovation. Second, a flexible road map for agricultural science R&D need to be made for responding to short and long term issues relevant to the innovation. Third, mutual exchange and cooperative system need to be constructed between academia and research in order to create synergy effects. Finally, both institutional improvement and humanistic literacy should be emphasized for rapidly changing conditions and better human life under the fourth industrial revolution.

  • This study developed indexes of farmers' acceptance factors for new farming technologies and evaluated the importance of the developed. For this study, farming technologies were classified according to the criteria established by the Rural Development Administration, and the Delphi technique was applied to evaluate the importance of the indexes. The indexes were composed of two tiers and evaluated by the analytic hierarchy process (AHP). Results showed that the importance of the first tier was finance and profitability with 43.9%, technology affairs 23.6%, labor environments 22.4%, and related industries and service system 10.1%. The importance of the second tier was the ease of technology acceptance 64.9% and technology completion 35.1% for technology affairs in the first tier, labor intensity 53.7%, work hazard 26.7%, working hours 19.6% for labor environment, farm income increment 69.9% and new fund required 30.1% for finance and profitability, and training and service system 66.7% and activation of related industries 33.7% for related industry and service system. This study may contribute to farmers' acceptance of new farming technologies and increase the efficiency and effectiveness of agricultural research and extension activities by the Rural Development Administration.

  • This study validates an abridged version of the age integration scale by Chung et al. (2015), which constitutes sub-dimensions of age flexibility and age heterogeneity-from Riley et al. (1994)-and observes disparities in the perception of age integration among different socio-cultural characteristics. This study analyzed 1,433 people in the "Age Integration and Generation Integration Survey" data, with the support of the Social Science Competency Enhancement Project (SSK) (supported by the Korea Research Foundation). This paper analyzed the data using exploratory factor analysis, confirmatory factor analysis, multiple-group factor analysis, and a compare means test. The results are as follows. First, the scale was abridged to 13 items from 28, of which eight items concern age heterogeneity and five concern age flexibility. Second, the multi-group analysis did not show a significant difference among younger, middle, and older age groups, therefore allowing the scale to be used among all age groups. Third, when sociocultural characteristics were observed, younger adults showed differences in their levels of age integration, age heterogeneity, and age flexibility regarding their residential area. Middle-aged adults showed dif f erences in their levels of age integration, age heterogeneity, and age flexibility regarding their residential area and social status. Older adults showed differences in their level of age integration regarding their residential area, education level, and social status. They also showed differences in the level of age flexibility regarding their residential area and social status and differences in the level of age heterogeneity regarding their residential area and education. Based on the results of the study, political and practical measures to promote perception on age integration in the future were suggested.

  • ESC has been used as a tool for evaluating overall performance of firms. ESC focuses mainly on building a balanced viewpoint comprising perspectives and their metrics. It is, therefore, difficult to value overall strategic achievements of a company derived by consolidating various perspectives and metrics. Because of the absence of a method for consolidating ESC metrics and computing total score based on these metrics, it is difficult to evaluate whole strategic performance and find core obstacle parts of performance. In this paper, we suggest a method of normalizing a numerical value of metrics with different units, and calculating the total score of ESC metrics. We conduct a case study of evaluating the effectiveness of CRM to illustrate the applicability and feasibility of the suggested method.

  • 기존 물관련 시스템들은 독자적인 DB 구조를 가지고 있고 검색 서비스는 자체 시스템의 DB를 직접 접근하여 사용자에게 결과를 제시하는 형식이다. 이러한 서비스의 단점은 사용자가 개별 시스템의 서비스에 대한 지식이 없으면 접근하기 어렵다는 점이다. 개별 시스템의 개별 서비스의 개념을 벗어나기 위하여 물관련 시스템에 있는 하천공간자료 검색 정보를 카탈로그 서버에 등록하고, 카탈로그 서버에 등록된 검색정보를 사용자가 검색하는 방식을 적용하고자 한다. 카탈로그 서버에 자료에 대한 정보를 등록할 때 자료의 정보를 어떻게 기술할 것인가의 문제가 발생한다. 개별 서버마다 등록하게 된다면 용어 및 문화에 의한 차이로 같은 개념을 다른 용어로 등록하게 되는 혼란이 발생할 소지가 있다. 예를 들어 강우자료에 대하여 "강우", "Precipitation", "Railfall", "비" 등으로 등록할 소지가 있다. 이러면 실제 자료가 존재하는 데도 등록 방법에 따라 자료의 검색이 어려워진다. 이러한 상황을 제어하기 위하여 검사어휘(Controlled Vocabulary)를 도입한다. 이는 포털의 운영자가 미리 용어의 개념과 용어의 분류체계를 설정하고 등록 자료의 검색어를 미리 설정하여 자료의 원천 소유자가 자료를 등록 시 검사어휘를 참고하여 등록하거나 또는 등록되지 않는 용어의 자료인 경우 이 용어를 포탈에 신규로 등록한다. 검색용어의 난립을 피하기 위하여 사용자의 신규등록은 포탈의 운영자가 어느 정도 제어할 필요가 있다. 검사어휘의 정립과 하천 관련된 분류체계는 하천공간정보 검색의 포탈을 위한 필수사항이다. 검사어휘의 정립의 주된 목적은 이질성의 극복이다. 이질성의 종류는 문법적 이질성, 데이터 형식과 구조 및 문맥적 이질성이 있다. 이 중에서 문맥적 이질성이 가장 넓고 어려운 문제이다. 단위는 분야마다 호칭이 다르고 채택하는 기준마다 다르다. 유사어는 전문용어라도 분야마다 다르다. 우리나라에서 서비스 인코딩시 국어와 영어를 어떻게 처리할 지에 대한 대책도 필요하다. 수문학의 시계열 자료를 다루는 CUAHSI/HIS의 온톨로지는 대 개념으로 물리학적, 화학적 및 생물학적인 분야로 분류하고 있다. 하천공간정보의 온톨로지 구축을 위해 데이터 분석 및 분류, 온톨로지 요소 설정, 온톨로지 데이터 테이블 작성, 클래스 생성 및 계층화, 클래스 계층화에 따른 속성 설정, 클래스에 적합한 개체 삽입, 논리 관계 확인 및 수정과 같은 과정으로 온톨로지 개발을 진행하고자 한다.

  • As the annual growth rate of port handling container volume in Korea has faced slowdown, this paper attempts to find strategies for the domestic container terminal operators in order to enhance competitiveness. For this, the model of using AHP and the fuzzy set theory is used for evaluating competitiveness between domestic and global container terminal operators. The evaluation model hierarchy is developed based on SERM(subject-environment-resource-mechanism) theory of business strategy. The results show domestic operators are ranked lower than global player so that they particularly pay attention to the areas of scale of economy, business diversification, and globalization strategy.

  • The toxics regulatory body provides a benefit/cost ratio as a justification criterion while implementing regulations that induce the industry to reduce emissions voluntarily. Furthermore, since, the body wants to reflect not only the efficiency standard but also the policy standard in the evaluation of feasibility, it calculates the ratio by adjusting the importance weights. The problem is that respondents answer ambiguously. It should be removed for the reasonable evaluation. This study introduced a fuzzy-AHP methodology for this, and applied it to the voluntary emission reduction plan program in Korea.

  • In Seoul, the capital of South Korea, developers of apartment complexes are responsible for including community facilities - senior citizen centers, child care centers, small libraries, and so forth - according to the current Regulations on the Housing Construction Standard Article 2 and 55. These standards have long required certain community facilities, depending on the number of households in each apartment complex, without fully considering whether such provisions meet that community's needs. In this study, we aimed to reveal whether the current provision of community facilities responds to local preference. We conducted surveys of residents in randomly selected ten apartment complexes in Seoul to determine residents' preferences on community facilities using the analytic hierarchy process (AHP). We then compared the survey results with these complexes' current facilities. Our findings showed mismatches between residents' preferences and provisions: outdoor sports facilities, child care centers, and small libraries were found to be strongly preferred, but not provided in some apartment complexes within the study, whereas less-preferred facilities such as senior citizen centers were provided in all complexes. Through this study, we could conclude that current standards regarding the provision of community facilities in Seoul's apartment complexes should be altered to reflect the preferences of residents in apartment complexes.

  • The purpose of this paper is to estimate technical efficiency, scale efficiency, and environmental efficiency by income level of Korean farms, and analyze the factors to decide three efficiencies. Depending on the non-parametric methods, we estimate technical using inputs and outputs of total farms without assuming of goods or behavior of optimization. The average technical efficiency of total firms under constant return to scale and strong disposability is 0.437. The technical inefficiency was caused by 47.7% in pure technical inefficiency, 11.3% in scale failure, and 3.2% in environmental inefficiency. The number of firms under increasing return to scale occupied almost 70% and 27% of total firms respectively. Higher are income class, middle debt & long debt per asset, and N effluents per cultural land, higher technical efficiency. The increases of BOD discharges per cultural land and machines per cultural land deteriorate environmental efficiency.
