물류환경의 급격한 변화와 함께 항만을 둘러싼 환경도 빠르게 변화하고 있다. 이와 같은 항만환경의 급격한 변화는 동북아지역을 중심으로 한 전 세계 컨테이너 물동량의 급속한 증가, 정기선사의 경영전략 변화, 부두운영업의 글로벌화, 물류중심화 선점을 위한 경쟁 격화, 선박기술의 혁신 등으로 나타나고 있다. 항만의 운영 관리 책임자들이 이러한 변화를 예측하고 이에 신속히 대응하지 못하면 그 항만은 경쟁에서 뒤지게 된다. 국내외를 연결하는 항만 간 경쟁은 국제적인 것이 일반적이어서 우리나라 항만뿐만 아니라 이웃나라 항만과의 경쟁에서도 살아남아야 한다. 특히 우리나라 항만은 전 세계적으로 항만 간 경쟁이 가장 치열한 동북아 지역에 위치하고 있어 더욱 강력한 경쟁력을 확보하지 않으면 항만 간 경쟁에 뒤져 국제무대에서 사라질 수밖에 없다. 이에 본 논문에서는 대형항만을 중심으로 이루어진 항만선택결정요인에 대한 기존 연구들을 살펴보고 이를 재고찰하여 중소형항만에 적용시키고 향후 방안을 제시하고자 한다.

Purpose: The green building certification system in Korea was introduced in 2002 and developed as an improvement version of the G-SEED(Green Standard for Energy and Environmental Design) system in 2013. This study conducts surveys targeting architectural designers and users on significance of certification assessment criteria for apartment buildings on the G-SEED system and examines the differential views between the two groups on assessment criteria. Method: First, The AHP(Analytic Hierarchy Process) method was used to find importance of assessment criteria and then the importances were compared with weighted points on the certification standard. Second, the t-test was used to investigate differential views between designer and user groups on certification assessment criteria based on drawn importances. Result: (1) While designer group considered land use and transportation, energy and environmental pollution, and water circulation management as more important, user group did material and resource, maintenance management, ecological environment, and indoor environment as more important. (2) Based on t-test results, sustainable energy, water circulation system, site management, habitat, acoustical environment, and light environment were found to be different on importance between the two groups.

This research focused on the priotity decision for establishment sriteria on the effects which environmental sculptures in urban area. The analysis performed in this study used the AHP(Analytic Hierarchy Process) that is recognized as a useful decision-making tool to select and evaluate alternatives through pairwise comparison in the context of hierarchical decision structure. The results obtained from the analysis drawn by collecting the professional opinions of 5 experts for environmental sculptures are as follows: 1. The orders of establish criteria priorities on environmental sculptures were harmony of environment> symbol> public> function. The harmony of environment was the most important priority because it showed the highest weight of criteria. 2. The alternative priorities of environmental sculptures were the meaning of work>setting place> social contribution> physical quality .The meaning of work showed the highest change in the weight of alternative. 3.The sensitivity analysis of environmental sculptures demonstrated that the rate of change in the alternative priorities of the public was stabilized although the criteria importance varied, while the harmony of environment, the symbol intimated and function of priorities has their rates of weight changed if the criteria priorities were high.

The purpose of study is to suggest the data on what residential choice elements have to be considered to be important when the apartments are planed in middle size cities. This study analyzed the environmental characteristics of Cheong-Ju city and compared the priority of residential choice elements by using AHP(Analytic Hierarchy Process). The results of analysis are as follows. 1) The rate of housing supply in Cheong-Ju city is low at $80.2\%$ and concentrated on small sized apartments. Furthermore, the educational and traffic facilities are very insufficient. 2) While residential choice in Cheong-Ju is heavily characterized by educational surroundings, it is less affected by economic aspects such as housing prices and the value of investments and accessibility to public transportations, distance to working places. 3) It is affected by residents' general characteristics like as sex, age, life cycle, education level, properties, home ownership, number of room and type of house they want. In conclusion, the middle size cities like Cheong-Ju need the large scale residential plans connected with educational considerations, focused on improvement in quality and outdoor space. In addition, it is recommended to make plans to satisfy the diverse needs of consumers.

This article attempts to examine the well-known law that the increasing returns to scale(IRS) is effective in the Internet business. The effect of IRS is one of the hottest issues in the Internet business sector. Many cases and survey studies support the fact that the IRS phenomenon exists in the Internet business. Executives in Internet business generally give a deep trust on this theory. As the Internet business grows, however, the boundary of the business becomes widened and complicated. And each category of Internet business is characterized with a different business style and economic behavior. It may, therefore, be dangerous to accept that the phenomenon of IRS is applied to all areas of Internet business. For this reason, the research for the close look into the IRS phenomenon should provide significant implications for the managers in the Internet business industry. This article divides the internet business into four sub-areas, and analyzes the IRS phenomenon using AHP/DEA-based full ordering technique. Interpretations are given, based upon the research results, for each sub-area of Internet business, as a guideline of setting business strategies for practical managers.

The purposes of this study were to identify the evaluation categories, areas, attributes of the hospital food service and to define the relative importance of the evaluation categories, areas, attributes of the hospital food service using analytic hierarchy process. A survey was conducted from January 8th to 25th in 2007. Questionnaires were mailed to the 310 directors of dietetic departments of hospitals that included 160 primary hospitals, 107 secondary hospitals, and 43 tertiary hospitals. The result of the analytic hierarchy process indicated that relative importance of evaluation category was 0.5259 for food service management and 0.3407 for nutrition care. The food service management consisted of four subcategories, which are equipment standard, sanitation, production, and delivery service. Sanitation(relative importance: 0.2652) was the most important area among the subcategories and it was followed by equipment standard(0.2067), delivery service(0.1864) and production(0.1848). The nutrition care has two subcategories, menu management and meal management. The relative importance of menu management(0.4174) was higher than that of meal management(0.3555). The quality of food service and nutrition care to inpatients can be improved by the evaluation system based on appropriate applications of the developed evaluation indicators for hospital food service systems.

In these days, recommendation service in mobile environments is in the limelight due to the spread of mobile devices and an increase of information owing to advancement of computer network. The restaurant recommendation system reflecting user preference was proposed. This system uses Bayesian network to model user preference and analytical hierarchical process to recommend restaurants, but static inference model for user preference used in the system has some limitations that cannot manage changing user preference and enormous user survey must be preceded. This paper proposes a learning method for Bayesian network based on user requests. The proposed method is implemented on mobile devices and desktop, and we show the possibility of the proposed method through experiments.

Partner relationship management (PRM) refers to processes and methodologies associated with managing the relationship between corporations and their partners. Recently, the importance of PRM has been increasingly emphasized, and it is considered as a core competitive factor for firms whose sales heavily rely on the intermediate distributor. In this paper, we identify key success factors for PRM system based on literature review on CRM system and interviews with domain experts, and prioritize them from two different perspectives, firms and partners, based on analytical hierarchy process. Partners responded that trust-building between firms and partners, quality of system, and satisfaction level for information system have high priorities, while firms responded that quality of system, information share, and trust building between firms and partners. Identified factors and evaluated priorities can provide a strategic guideline when planning the PRM system building.
