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.

이남주 慶星大學校 1998 論文集 Vol.19 No.1

In this study, flow field in the Sihwa Lake is predicted using the RMA2 model, which is a finite element model for solution of the two dimensional depth averaged unsteady shallow water flow equations. With the results of numerical simulation co-operation effect of Sihwa Gate and Tando Gate is investigated. From this examination it can be found that a new dredged water channel may be required for improvement in water quality of the Sihwa Lake.

SWMM model has an advantage of simultaneous simulation for watershed runoff of rainfall and pollutants, and the present study contains results of sensitivity analysis of rainfall and pollutants runoff from the Joman River basin A GIS tool has been used for drawing out topographic and geological characteristics of the watershed For preparation of input data for SWMM model, meteorological, subcatchment, and channel data have been collected and analyzed Results of sensitivity analysis showed that proportion of watershed and impervious areas was the most sensitive to peak discharge and total flowrate for rainfall runoff and that the washoff exponent was the most sensitive parameter for pollutants runoff.

열화된 SUS 316강의 시간-주파수 해석에 의한 비파괴평가

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.

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.
