The purpose of this research is to suggest a desirable framework to promote EDI system in the Korean trade and transportation industries. First, this thesis reviews the trend of introduction of EDI systems in foreign countries and investigates their characteristics by examining some cases. Then the problems, which the Korean industries would be confronted with during the course of introduction of EDI system, are identified and discussed. Finally, this thesis suggests that the logistics network should be developed as a main system of EDI to which sub-networks of trade and custom service are linked. This leading role of logistics metwork is necessary to the EDI system because logistics tasks for international movement of goods are expected to increase while tasks related to trade and custom services will decrease in view of recent changes in the world trade environments warning the unbounded competition in the global marketplace without border.

In this paper, we deal with the dual-depot heterogeneous vehicle routing problem with simultaneous delivery and pick up(DH-VRPSDP) in reverse logistics. The DH-VRPSDP is a problem of designing vehicle routes in a day of given vehicle to minimize the sum of fixed cost and variable cost over the planning horizon. Each customer can be visited only once according to the service combinations of that customer. Due to the complexity of the problem, we suggest a heuristic algorithm in which an initial solution is obtained by changing the customer and the vehicle simultaneously and then it is improved. A performance of the proposed algorithm was compared to both well-known results and new test problems.

Real-time supply chain environments based on RFID will be an important topic in future society; Nevertheless, adopting RFID in real industry SCM is still in its infancy. The aim of this paper is to develop the physical framework of a fully adopting RFID system from manufacturing to recycle phase and measure the effect. So, we built a simulation station with fully appling RFID and analyzed benefits with mathematic model. Then, specifying the advantages and improvement scheme for real industry limitations were suggested. This work concluded that fully appling RFID in SCM gives improvement of quality and service to both production and consumer.

This paper focuses on frequent flyer programs (FFPs), which have long been used by most airlines as a powerful marketing tool. Since the preference for FFPs reward services and the customer perceived values of mileage points differ among FFPs members, airlines should design a customer-oriented reward service based on customer preference to motivate the use of mileage points. The intention for using mileage points is affected by various kinds of attributes such as reword items, consuming mileage points for rewards and time of usage. In this paper, we focus on evaluating customer perceived values of attributes of FFPs reward services. A conjoint analysis model is applied to get the preference value of each attribute. Some empirical experiments are conducted in relation to Korean customers. From the empirical survey, the preference values of attributes are evaluated for different scenarios with respect to the number of mileage points. With the preference values of attributes, we can find several implications for airlines regarding the development of various FFPs strategies.

Recently, ordinary mail is decreasing continuously by the development of ICT (Information and Communications Technology) including E-mail, messenger service, and etc. On the contrary, parcel post is increasing by the increase of online shopping, home shopping, and etc. Aside from these changes, the demand for various mail acceptance and delivery means is increasing with the increase of single households and dual-income couples. To overcome these environmental changes, Korea Post installs unmanned post offices which are composed of various unmanned mail acceptance and delivery postal systems. In this paper, we propose the methodological approach for the site selection of unmanned post office among the existing post offices and the installation standard of unmanned postal system considering the operation cost by the mail volume.

공공도서관에서의 서평서비스는 이용자의 알 권리를 충족하는 동시에 전문직으로서의 사서 영역을 확장시킬 수 있는 중요한 분야이다. 따라서 사서들은 서평 관련 연수의 적극적인 참여 및 지역별 동아리 조직 등을 통한 지속적인 연구로 다양한 서평활동에 참여하여야 한다. 특히 공공도서관에서의 수준별, 계층별로 특성화된 서평서비스는 반드시 필요하다. 이러한 관점에서 본 연구는 국내 서평매체 분석, 사서의 서평교육 연수, 향후 공공도서관 사서의 적극적인 서평서비스 활성화 방안을 모색하는데 그 목적이 있다.

The purpose of this study is to review the historical development of British Museum Library and its cataloging rules which really marked the beginning of the modern era of cataloguing. The results of the study can be summarized as follows (1) Sir Anthony Panizzi was the most creative force in the history of the British Museum Library. He devoted himself to the formation of the British Museum Library cataloging policy and the compilation of printed catalogues. Moreover, he laid down the sound acquisitions policy and the vigorous a n.0, pplication of the copyright deposit privilege. He designed a great circular reading room and raised standards of library service and administration. (2) British Museum Library Cataloging Rules : 1. are notable for their pioneering efforts-this was the first major catalogue code-and for their influence on all subsequent codes. 2. introduced the concept of corporate authorship but has never dealt with problem very satisfactory. 3. went to great lengths to avoid title entry. 4. used a number of form heading, example for, ACADEMIES, PERIODICAL PUBLICATION, EPHEMERIDES, CATALOGUES etc.

The editorial department of Journal of Korean Neurosurgical Society[JKNS] polled more than 1,210 members of the Korean Neurosurgical Society[KNS] to evaluate the present status of JKNS from a viewpoint of readers or authors. The survey form includes questions about the impressions and opinions of JKNS regarding to its contents, style, and service. There responses were collected by means of e-mail and a total of 107 replies could be gathered during 2 months. Analysis of the responses revealed that majority of members of the KNS recognized the efforts to improve the quality of JKNS during recent years. However, there was also apprehensions and discontent about the quality of articles and review process in some KNS members.

Anaphylaxis is an acute systemic reaction caused by IgE-mediated immunological release of mediators from mast cells and basophils to allergenic triggers, such as food, insect venoms, and medications. An alternative definition was recently proposed as follows: anaphylaxis is a "condition caused by an IgE mediated reaction" that is "often life threatening and almost always unanticipated." The reaction can be severe enough to lead to the rapid onset of symptoms, including dizziness, upper airway occlusion, bronchial constriction, hypotension, urticaria, cardiovascular arrhythmias and possible cardiac arrest. The incidence or prevalence of anaphylaxis in Korean pediatrics has not known. Thus, Epidemiology of Anaphylaxis in Pediatrics based on the data from Korean Health Insurance Review and Assessment Service (KHIRA) from 2001 to 2007 and questionnaire to the member of Korean Academy of Pediatric Allergy and Respiratory Disease (KAPARD) who are working at the training hospitals was studied. The incidence of anaphylaxis under age 19 is 0.7-1.0 per 100,000 year-person. The causes of anaphylaxis based on data from KHIRA were unknown (61.7%), food (24.9%), medications (12.4%), and serum (1.0%).

기존의 데이터망과는 달리 B-ISDN은 데이터, variable-rate 비디오 등과 같은 bursty하고 variable bit rate를 갖는 트래픽원으로부터 smooth하고 constant bit rate를 갖는 트래픽원까지 광범위한 계층의 트래픽을 모두 수용해야만 한다. 게다가 이 망은 다양한 계층의 트래픽에게 일정 수준 이상의 품질, 즉 QoS(Quality of Service)를 보장해 주어야만 한다. 셀 손실이나 지연시간 그리고 지연시간 jittere등을 포함하는 QoS 성능척도들은 응용서비스 별로 서로 다를 것이고 특히 실시간(real-time) 응용 서비스를 지원하는 망에서의 QoS문제는 특별히 중요성을 더하게 된다. 따라서 통계적 다중화에 의해 얻어지는 망자원의 효율성을 확보하면서 end-to-end QoS 보장을 해주는 문제는 B-ISDN에서 매우 중요하나 아직 대부분 미해결 문제로 남아 있는 분야이다. 본 연구에서는 end-to-end 분석에 가장 큰 에로점으로 부각되는 multi-hop망 환경하에서 트래픽 분석에 초점을 맞추어 기존 연구결과등을 폭넓게 비교 분석하고 최근 연구 동향 및 추후 연구 사항을 제시하고자 한다.
