QFD is a method for supporting product planning and development processes. This method enables to specify clearly the customer's needs and then evaluate the product capability in terms of its impact on meeting those needs, The QFD process involves constructing the HoQ matrix which consists of the customer requirements, the engineering characteristics to meet those requirements, and the evaluation factors in the planning matrix. The QFD often produces different results according to each evaluation factor in the matrix. Therefore, am integrating technique is required to solve the problem. This paper provides the technique which integrates the QFD analysis results due to different evaluation factors. The technique also considers the production cost as an evaluation factor to help produce an economical solution. Finally, a software tool for supporting the comprehensive QFD process is developed and implemented using the Visual Basic of Microsoft Excel.

A recombinant human erythropoietin (rHuEPO) was administered intravenously at dosage levels of 0, 100, 500, and 2500 IU/㎏/day for a period of 13 weeks. There were no observed clinical signs and deaths related to treatment in all groups tested. Decreases in body weight gain and food consumption were observed only in males of 2,500 IU/㎏ group after 2 weeks. In hematological parameters, erythrocyte content, hematocrit values and hemoglobin concentration were dose-dependently increased in rHuEPO treated groups. The ratio between kidney weight and whole body weight was significantly increased in females of 500 and 2,500 IU/㎏ groups. The spleen weight was also increased in both sexes of 500 and 2,500 IU/㎏ groups. However, the absolute weight change of other organs was not observed. In histopathological examinations, the renal tubular basophilia was observed only in males and females of 2,500 IU/㎏ groups. From these results, it is concluded that the no-observed adverse effect level(NOAEL) of rHuEPO is 100 IU/㎏ in rats in the present study.

The purpose of this study is to compare the estimation methods for mean areal rainfall using ARC/INFO GIS system. Daily, monthly and yearly rainfall from Wi Cheon watershed are used to estimate the mean areal rainfall and 10 methods, Unweighted Mean(UM), Grouped Area-Aspect Weighted Mean(GAAWM), Thiessen Polygon(TP), Individual Area-Altitude Weighted Mean(IAAWM), Triangular AreaWeighted Mean(TAWM), Kriging(Kriging), Inverse Distance Weight(IDW), two-Axis(TA), Modified Polygon(MP), and Finite Element(FE) method are applied to ARC/INFO GIS system. To examine the variability of mean areal rainfall, the coefficient of variation is obtained from the each method and the result of Kringing method is used as the standard value and the average value of Kringing method is compared with the other methods. The mean areal rainfall of the existing procedures which use the topographical map are compared with those of ARC/INFO GIS system. The results of this study are as follows: (1) With the result from ARC/INFO GIS system it is shown that TA, IAAWM and FE methods have large values and GAAWM has small one. However there is little difference among those methods on the whole. (2) When the average value by Kriging method is used as the standard one, variation rates of average value about mean areal rainfall is not more than 4%, except GAAWM method. (3) The coefficient of variation of MP method has the maximum value and that of GAAWM method has the minimum one among the methods, However there is little difference among those methods on the whole. (4) The mean areal rainfall using ARC/INFO GIS system is almost similar to the existing methods which use the topographical map.

An experimental study is presented on the local and overall buckling of the square tubes made of mild steel. A total of 150 square tubes were axially loaded in quasi static loading condition. Three kinds of specimens were chosen according to the discrepancy of thickness to width. Based on th test results, a new domain for distinction of overall and local buckling is suggested on the square tube. It is different from that of the column. A experimental equation of the overall buckling is suggested.

主觀的 삶의 質과 行政의 評價

朴柄植 東國大學校 1988 論文集 Vol.27 No.-

The basic goal of public administration is to improve the quality of life of citizen. For achieving this goal, there is the necessity of the approach that the accomplishment of administrative affairs is directly linked with the life of citizen. Thus I study the concept of the 'quality of life' that was appeared at 1970 early and that comprised the societal goals. I suggest the historical implication of and the classified type of the 'quality of life'. And the methods to measure the 'quality of life' are the objective and subjective methods. The studies of the correlation analysis of two methods are practiced empirically by many scholars. Analyzing the studies of many scholars, I can understand that the relation of this subjective and objective methods has the character of the mutual support. Today the necessity of the subjective measurement is required espicially in Korean public administration. Because Korean public administration have the fundamental problems of people's view as passive beings, of research's shortage about citizen's substantial needs, and of superficial evaluation, the humanitalian approach is requested in public administration by means of reflecting the citizen's subjective thinking, that is, the subjective evaluation. For measuring the subjective thinking of citizen, I analyze the 'quality of life' and suggest it's 15 indicators. Also I survey the function of Korean public administration and suggest the 7 subfunctions of the local administration. And I make the model of the subjective measurement for administrative evaluation and for understanding the level of 'quality of life'. I practice the empirical test of administrative evaluation and the level of 'quality of life' on the base of the model in 4 districts of Kyong Ju Si, UI San Si, Po Hang Si and Uel Sung Gun. The result of this empirical survey shows that the subjective evaluation appears the valuative results. Though the subjective evaluation has its many limitations and its independent application is restricted to insufficient results, it has the important implication in supplementing the objective measurement and in discovering the practical facts. Thus the subjective evaluation is studied constantly in many fields of Korean public administration.

Recently, alternative fuels are drawing more attentions due to the increasing need for lower emission characteristics and fuel consumption rate in automotive engines. The GTL(gas to luquid) is the one of most favored candidates. It has higher cetane number(more than 75) and almost negligible sulphur and aromatic contents. Therefore, enhanced emission characteristics are expected even in the application in diesel engines without any modification. In this study, the cylinder pressure and heat release, emission characteristics with fuel injection timings are compared between diesel and GTL fuel in the single cylinder diesel engine. Noticeable reduction in PM, THC and CO emission are observed due to lower sulphur and aromatic contents in GTL. Also, the ignition delay decreased due to higher cetane number of GTL , which slightly decreased the amount of NOx emissions. With the retards of main injection timing. NOx decreases more for the case of GTL, while the level of THC and CO emissions still remains lower than the case of diesel. Therefore, there is much room for the control of injection timiing for NOx reduction without sacrificing THC and CO emissions. With the retards of main injection timing, Small size distribution of PM became lager and there amount increased. But from all conditions, size distribution of PM for the case GTL was lower than Diesel.

The regional development of each region until now had been practiced by policy initiatives and supports of central government. But nowadays the local problems and the planning of regional development are managed by the mayors and local coucils elected by civilians. In this situation, this study evaluates the effectiveness of mayor's, local council's and local government's fuctions and roles in the respective of civilian. And this study seeks the theoretical and institutional policies for accelating the regional development in minimizing the perceptional discrepancy between local government and civilian. The result of analysis is that civilian believe they have accomplished very insufficient Performance, though local council and local government are trying to achive their roles endeavorly. The mayors have accomplished their role of social welfare, security, industrial economy, constructing public good, and fulfilling public promise insufficient during last 1 year. The local councils have accomplished their role of democracy, specialization, responsibility, and confict mediation insuffient during last 1 year. The local governments have practiced the accomplishment of a long desired projects and the action of integrity incompletely. But the representative rote of mayors, the positive zeal of local council members and the service, kindness and vitality of local servants are appeared to achieve moderate performance. The factors to be supplemented for development of local autonomy are these following contents. First, the chosen mayors would promote the welfare project and the economic developmental policies consistantly. Sencond, local council members would accomplish the sincere activities forovercoming the paucity of specializafion and the pursuit of individual interest. For supplepmenting this, local government would enlarge the power of local council and increase the working date for making council members accomplish the sufficient activities. Third, local servents would practice the diverse endeavor to get the sufficient local budget and to overcome the peace-at-any-price principle and the indifference of civilian for maturing local autonomy. And political supports are prepared to guarantee the enlargement of the power of local autonomy and the specialization of public servants
