이 글에서 저자는 국제이주과정에 대한 경험적 연구에 준거해 볼 수 있는 이론적 지침으로서 행위체계론적 접근을 제안하고 있다. 이 제안은 다음과 같이 일련의 이론적 검토와 평가를 통해서 이루어졌다. 먼저 국제이주과정의 국면별 연구, 즉 이주의 발생 과 영속화 및 이추자의 적응과 정착 연구에 적용되어 온 주요 이론적 관점들을 검토하였다. 그리고 이 검토를 통해서 이주의 각 국면에 영향을 주는 요인들은 상호배타적이 아니기 때문에 관련된 모든 주요 요인들을 총체적으로 파악할 수 있는 이론적 접근이 요구된다는 것이 주장되었다 국제이주 연구에서 행위론적 접근을 주도하여 온 신고전 경제학적 접근은 그 기본 가정 , 즉 합리적 행위 가정의 한정성 때문에 맑스주의 정치경제학에 뿌리를 둔 구조론적 접근에 의해서 강한 도전을 받았다. 그 도전을 주도하여 온 노동시장분절론과 세계체계론적 접근 등은 이주의 큰 흐름을 결정하는 거시구조적 요인을 구명하는 데에는 상당한 성공을 거두었다. 그러나 이주행위의 상황적 요인, 특히 사회문화적 요인을 탐구하는 데에는 한계가 있음이 지적되었다. 이에 따라 이 논문의 저자는 국제이주과정을 총체적으로 파악하기 위해서는 이주현상을 행위체계론적 관점에서, 즉 이주자의 지향 대상이 되는 모든 상황, 즉 경제적, 정치적, 사회적 및 문화적 상황을 상호연관해서 총체적으로 분석하는 것이 필요하다는 것을 제안하게 되었다.

Globalization changes in market structures and consumer needs, as well as technology innovations force organizations to adopt new structures and collaborative networks to cope with rapidly changing environments. These Collaborative Networks are based on the Idea of virtual enterprise. A virtual enterprise(VE) is a temporary alliance of globally distributed independent enterprises that share core competencies and computer networks. This paper presents a proposal for a methodology to measure a key factor of success and risk First of all, we chose thirty experts' defines on virtual enterprise, fifteen are academic specialist and other fifteen are from industry. For this study we define twenty two factors determining VE's success and seventeen factors determining VE's risk using by Delphi method. And we built the influence model on virtual enterprise. A research model was established according to preceeding research and consensus on experts then the revised model of key factors on virtual enterprise. This survey was based on the Analytical Hierarchy Process (AHP). AHP is an approach to decision making that involves structuring multiple choice criteria into a hierarchy, the assessing the relative important of these criteria, comparing alternative for each criteria, and determining an overall ranking of the alternatives. A model was constructed as 3 level hierarchy. The hierarches are organizational, strategic, technical criteria. for success model on VE has 22 factors and 17 factors for risk model. They are selected by all 30 experts. 14 copies among 30 copies distributed to carry out on the Analytical Hierarchy Process (AHP). Consistency ratio confirm high validity and reliability of instrument and support theoretical model. The results of this study are summarized as follows. (1) This study presented success on VE influenced strategic criteria, and essential factor is Creating a value. Risk on VE influenced strategic criteria, and essential factor is Outcome/Distribution. (2) Its enable that ranking the criteria influence on VE. These are supported VE management and using guideline of VE.

Purpose: Many patients in anti-platelet therapy have been consulted for bleeding risks before minor oral surgery. However, there has not been an established pretreatment protocol for treating these patients. The purpose of this study is to make a protocol for the preoperative management for patients in anti-platelet therapy. Patients and Methods: The existed consultation pattern of patients was examined in the Department of Oral and Maxillofacial Surgery, Yonsei Dental Hospital. Based on the observation, a protocol including classification of medical status of patients and the type of oral surgery in need was introduced. This protocol had been performed for 6 months. Result: Following this protocol, the frequency of consultation for bleeding risk was decreased. The number of minor oral surgeries with concurrent anti-platelet therapy was increased. There was no severe bleeding event observed among minor oral surgeries that were performed while maintaining anti-platelet therapy. Conclusion: This protocol can be used as a guideline for clinical practice of patients in anti-platelet therapy requiring minor oral surgery.

Resort Hotel Rate System was first introduced as an official guideline after Tourism Promotion Act, which enables the secretary of transportation to rate resort hotel by its facility and accommodation, was enacted on January 18, 1971. And the system was modified time to time to what we currently have after numerous revisions. However, the system has made a slow progress compare to the other countries system and have shown many potential problems that need to be improved. There is a problem that it is not even clear whether the act is as effective to apply it to rate any resort hotel in reality. The hotel rate system was first introduced in 1970's and changed ever since, and it also changed the private organizations to audit the decision. However, unlike the hotels in other countries, our hotel rating system is not focus on the customer's service and informations. It focus on the hotel's quality so that cause the problem whether the hotel is for customer or not In other different countries, they have some specific standard for evaluation of customer service based on customers' reference or needs. However, there is no evaluation part concerning on customer service in Korea. Also, even the hotel rating system is not based on the hotel waitress or waiter's service part. It means the system is almost focus on the hotel's qualities. Therefore, customer who needs hotel service, can not trust whether they can choose the hotels which gives the right informations and good quality services. Although hotel's physical layout is important, the service part is also important for evaluating the hotel entirely. There are a lot of things to develop and to be changed in order to develop tourism industry in the process of decision about Hotel's level in Korea Thus, this research will summarize some problems which are revised through the former research of hotel's level. And it will compare the system of hotel's level between Korea and developed countries in hotel industry Additionally, I will show current tourism industry in Korea. Finally, I suggest the improvement proposal for the level system of hotel in Korea and process of this system in the future.

We develop guidelines for the quality assurance of radiation treatment planning systems (TPS) by comparing and reviewing recommendations from major countries and organizations, as well as by analyzing the AAPM, ESTRO, and IAEA TPS quality assurance guidelines. We establish quality assurance items for acceptance testing, commissioning, periodic testing, system management, and security, and propose methods to perform each item within acceptable standards. Acceptance includes tests of hardware and network environments, data transmission, software, and benchmarking as specified by the system supplier, and apply the IAEA classification criteria. Commissioning includes dosimetric and non-dosimetric items for assessing TPS performance by applying the AAPM classification criteria and the latest technical items from the IAEA. Periodic quality assurance tests include daily, weekly, monthly, yearly, and occasional items by applying the AAPM classification criteria. System management and security items include the state and network connectivity of TPS, periodic data backup, and data access security. The guidelines for TPS quality assurance proposed in this study will help to improve the safety and quality of radiotherapy by preventing incidents related to radiotherapy.

There is an overall guideline of the installation of air quality monitoring stations in Korea, but specified steps for the selection of monitoring sites for hazardous air pollutants(HAPs) are not provided. In this study, we proposed a systematic method for the selection of monitoring sites for HAPs using geographic information system (GIS). As a case study, the Seoul metropolitan area (Seoul, Incheon, and Gyeonggi Province) was chosen, and 15 factors including population, vehicle registration, and emission data were compiled for each grid cell ($7km{\times}7km$). The number of factors above the top 30% of individual data for each grid cell was used to select priority monitoring sites for HAPs. In addition, several background sites were added for data comparison and source identification. Three scenarios were suggested: Scenario 1 with 7 sites, Scenario 2 with 17 sites, and Scenario 3 with 30 sites. This proposal is not the final result for an intensive monitoring program, but it is an example of method development for selecting appropriate sampling sites. These results can be applied not only to HAPs monitoring in megacities but also to the national HAPs monitoring network.

Purpose: The history of biometry dates back to ancient Greek. The ideal body ratio from biometry is used as a guideline in many works of art. Biometry is also used as a medical standard to determine normal or abnormal. Since the biometry of face is so complicated, many surgeons tend to regard preoperative evaluation as a bother and substitute medical records with some photographs. We introduce a new method to measure $MRD_1$ and levator function using digital photographs, which becomes widely used lately. Methods: $MRD_1$ can be measured with the primary-gaze-view photo which is magnified by PhotoshopR 7.0.1. The distance from coneal reflex of ring flash to upper eyelid margin is converted to mm-unit using the piece of ruler attached on the patient's face. Levator function can be measured with up-gaze-view photo and down-gaze-view photo which are superimposed on another. The excursion distance of upper eyelid margin (a) and the excursion distance of eyebrow (b) are measured respectively. The levator function can be assessed through subtraction of two values (a-b). This method is simple and precise and can be applied directly to patient without photos. Results: Using magnified digital photos and computer, this method can reduce personal error and instrumental error. Taking some digital photos doesn't take long time, so it can reduce the effort of preoperative evaluation and discomfort of patients. Conclusion: Digital photo-biometry is useful for retrospective study. Especially reducing personal error, it is useful when the number of specimens is huge. New levator function test is much more useful for Asian-specific eyes than Berke's method allowing frontalis muscle compensation.
