시설 입지 선정 문제는 1960년대부터 수리적 모형의 개발을 통해 광범위하게 다루어져 왔었다. 하지만, 호텔 산업에서의 경영과학 관점의 접근을 통한 호텔의 최적 입지 선정은 매우 제한적으로 다루어졌다. 본 연구에서는 제한된 예산 하에서 새로운 비즈니스호텔의 최적 입지와 객실 수를 결정하기 위한 수리적 모형을 개발하였으며, 해법 방법론으로써는 유전 알고리즘을 개발하였다. 제안된 수리 모형과 유전 알고리즘은 서울특별시 내에 위치한 실제 대기업 본사 위치 데이터와 임의의 호텔 데이터를 이용하여 실험하였으며, 최적의 호텔 입지와 객실 수를 짧은 시간 안에 도출해 냄으로써 그 타당성을 검증하였다. The Facility location challenge has been widely addressed by using various mathematical models since 1960s. However, there are not sufficient Operation Research perspective approaches on the location problems throughout the hotel industry. In this study, we developed a mathematical model to optimize the location and size of new business hotels within their budget restrictions. As a solution approach, a genetic algorithm was developed. A proposed mathematical model and a genetic algorithm were tested using the real data of head offices and using hypothesis hotels data in Seoul metropolitan city. A Proposed mathematical model and a genetic algorithm were examined via numerical example by deriving the optimal location and size of new hotels in a reasonable time.

Capacitated Location and Allocation Models of Long-Term Care Facilities
송병덕,고영대,제임스모리슨,황학 대한산업공학회 2013 Industrial Engineeering & Management Systems Vol.12 No.3
People are living longer than ever before. As a result, life expectancy is going up and the demand of long-term care facilities is increasing in most countries. The facilities provide rehabilitative, restorative, and skilled nursing care to patients or residents in need of assistance with activities of daily living. This study deals with the capacitated location and allocation problem of long-term care facilities in a city that consists of a finite number of regions. Assuming that in each region candidate locations for three types of facilities are already given, two integer programming models are developed under the closest assignment rule reflecting the demand characteristics of the facilities. Both the location and type of the facilities to be built become decision variables. To show the validity of the models, numerical prob-lems are solved with commercial software, CPLEX. Also, sensitivity studies were conducted to identify relationships between the system parameters.

Microstructure of polycrystalline Lead Telluride was controlled by the change of sintering conditions. Three properties which determine the thermoelectric figure of merit of the material were measured in the temperature range of 300-650K in order to investigate the effect of each sintering condition on the thermoelectric efficiency. Based on the observed experimental results, defect structure is concluded to be more important than microstructure though both can be controlled by processing variables.

體育指導의 基本的인 問題와 方法論에 있어서의 社會性의 指導와 健康指導
宋秉悳 忠州大學校 1981 한국교통대학교 논문집 Vol.14 No.2
There are inseparable relation between the individual life and his society, and all of the people is capable of survival from their good health. So I dare say that a good health must be the most important thing in our life. Accordingly this study focussed the aim on guiding to keep a good social life through a good health. I hope this study should more or less affect to promote the health of the nation and its social life, and it is more effectual for them to carry it out on their practical life.

The aim of gymnastics should be established in accordance with that of the school gymnastics and on this basis more effective plan should be made and carried out. It is necessxry to have certain facilities, tools, expense, and leaders. Staff members and students must be well orgamyed in order to carry on this smoothly. The works to do ofter athletic meeting are; to keep many tools and objects inorder, to clean the stadeum, to keep records, to give thanks to those who devoted to the meeting, to send letters of thanks to open the evalustion meeting of those concerned, to return many things borrowed. Ofter athletic meeting, it is necessary to keep score, and merits and faults of the game process so that the next meeting can be carred out more smoothly.

There are Various traditional arts in korea. However, the wrestling Peculiar to korea gives an impression like a national sport. The objects of the korean wrestling are to Promote mutual friendship and to improve physical conditions. And it has been played as a healthy sport of a recreation. They held the Wrestling Contest in most parts of the country on the Dan-O(the 5th day of the fifth lunar month) of on Chu-Seok (the 15th of August by the lunar Calender) to cultivate courageous mental Power and to harden the body . A thousand of People gathered together from various parts of the Country when they held the wrestling contest. And the wrestling of the younger generation has been Prosperous in that way in korea.

With legislations and customers’increased attention to environment issues, interests on reverse logistics have been increased. In this paper, we address a design issue of reverse logistics network with the objectives of minimizing total establishment cost of collection centers and transportation cost of collected end-of-used product by determining the locations of centers, reverse logistics network and minimum quality of end-of-used product to be collected. We propose mathematical model and genetic algorithm to support such decisions. Validity of the proposed genetic algorithm was tested via numerical experiments with various distributions on the quality of end-of-products.
