The modern decision environment is characterized by the presence of multiple objectives or goals, which are generally competing or conflicting. Therfore, it has been well established that virtually every decision making problem involves several key criteria. Mathematical programming techniques based on a single objective criterion such as cost minimization or profit maximization are restricted in application to real-world problems. Radford (14) contended that the goal of a global optimum solution should be discarded when considering complex and multiple objective decision problems. Under the modern complex decision environment, it is necessary to simultaneously consider all of the multiple and often conflicting objectives appropriately in selecting a best strategy or policy. Among the various techniques which have been developed to handle multicriteria decision making problems, goal programming is perhaps the most promising approach as it is an appropriate, powerful, flexible, and pragmatic tool. This technique was originally introduced by Charnes and Cooper (2, 3), and further developed by Ijiri (g) and Lee (11). The goal programming model can be solved through the use of a computer program based on an iterative algorithm. Currently, the most widely used computer program is Lee`s program (11) written in Fortran. Another popular algorithm was developed by Ignizio (7). Lee`s and Ignizio`s programs were designed using the modified simplex method. Lee`s and Ignizio`s programs did not consider efficiency in terms of the running time and storage requirements. Computational inefficiency results from unnecessary information being computed from iteration. to iteration. Recently Arthur (1) attempted to design a more efficient algorithm. This algorithm was tested in comparison with Lee`s algorithm in terms of computational time. Arthur`s goal partitioning algorithm is more efficient than the other two algorithms because it reduces the number of computations by modifying the matrix size when the number of subproblems increases and by eliminating unnecessary nonbasic variables. The critical disadvantage of this algorithm is its inability to provide the final optimal simplex tableau required to perform sensitivity analysis. This paper presents a new efficient GP algorithm based on the product represenation of the revised simplex method in order to overcome deficiencies of computational inefficiency on the part of the Lee and Ignizio algorithms and the lack of the final simplex tableau on the part of the Arthur algorithm.

The objective of this study was to investigate clinical manifestations of lower extremity edema (LEE) in endometrial cancer Medical records for LEE and/or responses to the Gynecologic Cancer Lymphedema Questionnaire (GCLQ) were evaluated in 177 patients with endometrial cancer Patients had a median age of 53 years. Sixty-seven patients (37.9%) had past (9 patients, 13.4%) and/or current patient-reported LEE (58 patients, 86.6%). Symptoms reported on the GCLQ in over 20% of respondents were swelling, numbness, aching , and heaviness. GCLQ total symptoms score was significantly higher in patients with current LEE. Most of the LEE (43/67, 64.2%) developed within 12 months after surgery and LEE lasted more than 6 months in most patients (56/59, 94.9%) Prospective clinical trials are needed to know the clinical significance, impact on quality of life, and preventive strategy of LEE in patients with endometrial cancer

싶다' 구문의 격과 부가어 : HPSG의 확대 논항 구조적 분석 An Extended Argument Structure Analysis in HPSG

최종주,이남근 대한언어학회 2000 언어학 Vol.8 No.1

Choe, Jong-Joo and Lee, Nam-Geun. 2000. Case and Adjunct in the Siphta Construction: An Extended Argument Structure Analysis in HPSG. Linguistics 8-1, 133-152. The siphta construction in Korean shows some intriguing properties such as the case alternation in the complement NP of the lower verb and the optional - but not arbitrary - case marking on the adjunct. We will show that the 'argument structure' alone is not enough to deal with the case marking on the adjunct simply because the adjunct cannot be contained in the argument structure. Therefore, in the framework of Head-driven Phrase Structure Grammar (HPSG for short), we will take advantage of the new feature DEPS (or dependendy structure) proposed by Bouma, Malouf and Sag (1999). The extended argument structure DEPS will enable us, with the help of Case Principle and the notion of structural/lexical case, to take care of the case alternation and case marking on the adjunct in the siphta construction.

Objectives : To observe the effect of acupuncture treatment and western medical treatment on frozen shoulder patients. Methods : 39 voluntary patients were randomly assigned to the Eastern treatment group(E group, n=22) and the Western treatment group(W group, n=17). The E group received acupuncture treatment on LI15, TE14, GB21 and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for 4 weeks. The W group received suprascapular nerve block, subacromial injection and trigger point injection, twice a week for 4 weeks. Both groups were instructed to practice self exercise during their daily lives. Evaluations were made before treatment and after treatment using Constant Shoulder Assessment(CSA), Shoulder Pain and Disability Index(SPADI) and the patient's satisfaction concerning the treatment was measured by Visual Analogue Scale(VAS). The obtained data were analyzed and compared. Results : The E group showed significant improvement(p<0.05) according to the CSA and SPADI. The patient's satisfaction scored 5.67 on a scale of 10. The W group showed significant improvement(p<0.05) according to the CSA and SPADI. The patient's satisfaction scored 7.73. But the difference between the two groups were insignificant according to CSA and SPADI. Conclusion : Both acupuncture and nerve block treatment significantly improved frozen shoulder. But the difference of the two treatments was insignificant.

多國籍企業에 대한 「R·버논」의 思想과 理論

李南柱 啓明大學 産業經營硏究所 1977 經營經濟 Vol.8 No.1

Raymond Vernon is the Herbert F. Johnson Professor of International Business Management at the Graduate School of Business of Business Administration and the Director of the Center for International Affairs at Harvard University. His distinction in the field of international business has been recognized by his role in organizing a long-term, large-scale study of multinational enterprises(generally known as Harvard Multinational Enterprise Project) and through a series of eminent books and articles he has produced in the field. Possibly the book for which he is best known is Sovereignty at Bay: The Multinational Spread of U.S. Enterprises, a synthesizing volume of his thoughts and theories on multinational enterprises(MNEs) based upon the Harvard research results. In this volume, he briefly overviews the 187 American-controlled MNEs, dissects their organizational structures, and describes their multinational spread in raw material and manufacturing industries throughout the world in connection with the product cycle model. He also assesses the impact of the MNEs on the economies of advanced and developing host countries and explores the past, present, and future relationships between MNEs and the nationstates. As Professor Vernon has published, edited and written so many books and articles, it is almost impossible to enumerate all of his academic works. But among his recent publications is a book on the role and tasks of a manager in a dynamic world of multinational firms: Manager in the International Economy, the 1976 revised edition coauthored by Louis T. Wells. He is now preparing another challenging book on MNEs, which will be titled Multinational Enterprises and National Governments: Exploration of an Uneasy Relationship, to be published in 1977. MNEs according to Vernon, are largely formed in oligopolistic industries dominated by comparatively large firms and characterized by high entry barriers. He classifies this oligopolistic industries in which MNEs predominate into several different kinds: mature oligopolies, innovation-based oligopolies and so forth. As this classification implies. he points out a number of characteristics of MNEs. The first is the sheer size of an efficient unit of production. The second is the advancement and complexity of technology involved, and the third is a well-designed international marketing organization. These characteristics may be considered as the conditions for multinational spread of .U.S. business firms. Vernon states that these conditions affect the oligopolistic power of a multinational firm and the relationship between MNEs and nation-states. These are also the major factors that determine the future of MNEs. The highlight of Vernon's academic achievements is his product cycle model which has contributed significantly to a better understanding of the evolution of U.S. MNEs. In the product cycle model, a firm's international involvements follow sequential stages in the life cycle of the product it innovates. The sequence begins with the "new product stage" in which the product is developed and manufactured in the United States, and introduced into foreign markets through exports. The high per capita income and the relative availability of productive factors are some of the reasons why demands are created and new products are innovated in the United States, In the "maturing product stage" as foreign demand expands to the point that it can support a production facility of economic size, the enterprise is induced to produce abroad-generally in other advanced countries. In a third stage, the "standardized product stage", production shifts to low-cost locations in the developing countries from which goods may be exported back to the home-country and other markets. Analytical rationale for these stages and their weaknesses are discussed extensively in this paper. In his approach to the MNEs, Vernon regards them as possessing potential for positive economic contribution. He contends that in developing countries the MNEs, despite repatriated profits and royalties, have helped to raise income levels and to facilitate economic development. Although he admits that the evidence of positive effect is not always unambiguous, he asserts that the economic gains enjoyed by the host countries have exceeded the costs by a satisfactory margin. The major problem connected with the MNEs, according to Vernon, lies in the asymmetrical nature of relations between MNEs and the nation-states which causes the inevitable conflict and tension between the two sets of institutions are:(1) the sovereign state has certain goals, but the local subsidiary of a foreign MNE is not fully responsive to the host government-it responds also to commands of the parent company and to the government of the parent company: (2) the MNE yields tremendous economic power and has flexibility and wide range of options in making decisions: (3) the total firm, with all its subsidiaries, "is not account-able to any public authority that matches it in geographical reach." For a solution, Vernon searches for a mechanism by which some supranational authority, matching the MNEs in strength and geography, can be established to control them. He also believes that effective controls over the MNEs can be achieved through the negotiation of multilateral agreements, which he regards as preferable to unilateral efforts by individual countries in the form of joint ventures or divestiture programs. On the prospects for the future of U.S MNEs, Vernon is fully convinced that the predominance of U.S corporations over those of the European and Japanese will be continued for considerable years to come. He stresses that the superiority of U.S enterprised in their research and development ability will be maintained, so they will continuously hold their prominent position. The critiques offered by the paper can by briefly summarized as following: Vernon gives the impression that the "product cycle model" and "economies of scale" can almost exclusively account for the rapid globalization of American businesses following World War Ⅱ. It is contended in this paper, however, that the phenomenon can be explained just as easily in terms of the foreign economic policies pursued by the United States. It is also pointed out that Vernon has not presented sufficient evidenced that an "arms-length" quality has characterized the relationship between the United States government and the MNEs. It can also be shown that many of the developed countries other than the United States are becoming important innovating countries with the implication that the first stage of a product cycle model could be started somewhere in the developed nations besides the United States.

지금까지 퓨리에 변환이 신호 처리법으로 가장 널리 사용되고 있다. 그러나, 이 방법은 신호의 주파수 성분이 시간에 대하여 어떻게 변화하는지를 표현하지 못한다. 따라서, 최근 이와같이 비정상신호를 표현하지 못하는 퓨리에 변환의 단점을 보완하여, 신호의 시간과 주파수에 대한 정보를 동시에 표현할 수 있는 시간-주파수 해석법들이 개발되기 시작하였다. 본 연구에서는 인공열화된 SUS 316강의 초음파 신호를 시간-주파수 해석법으로 분석하였다. 특히, 단시간 퓨리에 변화법과 위그너 빌 분포법을 이용하여 초음파 신호의 주파수 성분과 특성을 분석하였다. Fourier transform has been one of the most commonly used tools in study of frequency characteristics of signal. However, based on the Fourier transform, it is hard to tell whether a signal's frequency contents evolve in time or not. Recently, to overcome Fourier transform fault, not to represent non-stationary signal, time-frequency analysis methods are developed and those can represent informations of signal's time and frequency at the same time. In this study, we analysed ultrasonic signal for degraded SUS 316 with time-frequency analysis method. In particular, the methods such as short time Fourier(STFT) and Wigner-Ville distribution(WVD) were used to extract frequency contents and characteristics from ultrasonic signals.

Background : Previous data have been reported that subtype B is prevalent in South Korea, but neither the extent nor the proportion of subtypes could be evaluated. This study was designed to analyze the distribution of HIV-1 subtypes, temporal instructions and transmission dynamics between epidemiological groups. Methods : 1,280 Koreans had been diagnosed as HIV seropositive during the period 1985 to 2000. Among them, 134 individuals were selected for this molecular epidemiological study. 134 DNAs were isolated from uncultured or cultured peripheral blood mononuclear cells. V3-V5 (0.7 kb) fragment of HIV-1 env gene was amplified by nested polymerase chain reaction and was sequenced. Results : HIV-1 isolates from thirty-seven homosexuals were all subtype B (100%). On the other hand, 66 isolates from 94 heterosexuals were subtype B (70%) and 28 were non B subtypes (30% : 13 A, 4 C, 2 D, 8 E , 1 G). Only subtype B strains were isolated from 73 males who were infected with HIV inside Korea while 16 B and 20 non B subtype strains were isolated from 36 males who were HIV infected outside of Korea. However, B and non B strains were isolated half and half from females who were infected inside Korea except one. Conclusion : The HIV-1 subtype B strains are prevalent in Korea from the early HIV infection until present in both homo and heterosexuals. Non B strains have been transmitted from men who were infected outside Korea to their spouses and casual partners. So, we need further study to monitor subtype B and non B HIV transmission in epidemiological groups of Korea, (Korean J Infect Dis 33:311∼318, 2001)
