The purpose of this paper is to construct model which can be applied to the plan for preventing the road traffic vibration, and to analyze the primary factor an character based on the road traffic vibration. The predicting model was developed by quantification theory type I and step wise regression analysis with traffic condition as descriptive variables and vibration - rating value as objective variable and each model was compared and evaluated. The major results of this paper may be summarized as follows : (1) The correlation coefficient between traffic volume and ?? was 0.93, 0.98. (2) The correlation coefficient between the number of large - size car and ?? was 0.9, 0.93. (3) The correlation coefficient between ?? was 0.9 Through any of the degrees of appraised value are used, there is no problem. But the value of appraisal must be laid down considering the relation to human life. (4) We can anticipate the road traffic vibration better using the quantification theory type 1 than the step wise regression analysis.

The purpose of this study is to identify the bureaucratic level and functions of the elementary school organizations in Busan. Specially, this study identify the differences of Bureanucratic level and functions of the school organizations in terms of the fourdation of the school, principal's age and academic carees. A survey research was adopted using the questionnaire (SOBI; School Organizational Bureaucracy Inventory) which is composed of 22 items to measure school organization bureaucracy level and functions. The result of this study may be summed up as follows. 1) The degree of bureaucratization in elementary schools is totally a little bit higer than medium level. 2) The functional tendency of bureaucratization in elementary schools is more appearent than dysfunctional one. 3) Both public schools and private schools are on a high degree of bureaucratization but there is no significant difference between two groups. 4) There are no statiscal differences of the degree of bureaucratization and functions in terms of the principal's academic history and career but for their age. 5) Especially, 50's of age prinipals are interrelated with the high degree of bureaucratization in schools.

學校組織經營 效果性測定 評定에 관한 硏究

河甲洙 釜山敎育大學 1986 부산교육대학 논문집 Vol.22 No.1

Effectiveness is one of the most pervasive yet least delinated organizational constructs relevant to all in organizational life. But there is so many variables affects organizational effectiveness that it is very difficult to make the reliable general criteria to measure and rate, especially in school organization. In this study, it is attampted to review the theoretical approaches to organizational effectiveness and suggest a measurable effectiveness criteria of school effctiveness. Two general approaches, a goal perspective a system resource model, dominate the study. The differences between the two, seem more a matter of semantics than substances; therefore, the opproaches can be merged to form a single, integrated goal system resources model for the analysis of organizational effectiveness in schools. Administrators attempting to improve the effectiveness in schools must engage in planned organizational change. Such change can be brought about by individual technostrutural, surrey feedback, and organization development strategies. for maximum effectiveness all of the strategies should be employed in concert. The theoretical approaches involves a) goal approach b) system resource approach c) interal process d) participant satisfaction approach e) ecological approach. In terms of these approaches, the demansions of school organizational effectiveness involves a) goal achievement b) organizational integration c) maintanace d) adaptation. The goal achievement criteria are student achievement, productivity, utility of resources and goal focus. The organizational integration criteria are student's satisfaction, teacher's job satisfaction, cohesiveness, leadership, communication and decision making process. The maintance criteria are We-consciousness, achievement motive and confidence. The adaptation criteria are flexibility, innovativeness and autonomy. The effectiveness dimension rating scale are presented in the figure 10.

It is the purpose of this study to have an analytical review of the effects of the in-service education for the primary and secondary school teachers. The effects are evaluated according to following six areas; 1) educational belief system, 2) curriculum, 3) educational methodology, 4) evaluation, 5) shool administration and 6) R & D. In an oversimplified way, I can answer my original research question by conculding that 1)about 30% of the respondents were highly helped to refresh or reconstruct their educational beliefsystem through the course, 2) about a quarter of respondents were helped to study the modern school curriculum, 3) about 13% of the respondents were effectively helped to develop their educational teachnology, 4) about 10% of them were effectively helped to study educatiooal mesurement and evaluation, 5) about 37% of the respondents were helped to have theories and skills for the school administration(most of them are school administrators) and 6) about 18% of them were effectively helped to study more about R & D. The importance of the in-service education is gradually being emphasized in every field of occupations. But as we saw above, the effcts of in-service program are far below the expected level. In a word, it suggests us to have more objective study and to reform the program of in-service education for the primary and secondary teachers. Following recommendations may be suggested; 1)all of the in-service education should be integrated into the program of the legal institution, 2) the program should be organized in relation with the problems of the current educational movement, 3) to have a rapid educational innovation, the in-service educauion for the school administrator may be preceded.

金甲洙 嶺南大學校 工業技術硏究所 1994 工業技術硏究所論文集 Vol.22 No.1

Nowdays, traffic noise produced in the roads due to a rapid increase in traffic volume raises various problems. It is not only extending a wide scope of area by the influence but also infringing on agreeableness of life. Road construction projects induce a change of human society in the circumference and natural environment because of effects in the area change under construction of ecosystem, noises, air pollution (and so on) in the area for running an automobile after construction work. As a result, the purpose of this research presents a plan of optimum design, deciding barrier height, length(and so on) cosidered attenuation effect at the receiver point by means of diffraction of sound or interception of sound porduced in the road. Finally, surveying noise in the establishment section of existing noise barrier can be confirmed with validity in the field.

In order to overcome the weakness of previous studies an the average-based customer satisfaction, bus service evaluation technique was proposed in this study. A perceived service(i.e. perception of service quality, mobility, transfer and economy) and stated preference survey were conducted to investigate passenger’ consciousness toward bus service. The analysis results from study are as follows; The likelihood ratio of evaluation model for bus service established in mixed multinomial logit model is 0.259 and the hit ratio is 62.1 %. It was found that the ratio is far better than the model established by multinomial logit model. Standard deviations of some variables like accessing time, travel time, comfort of driving, information sign, 1ow floor bus and standing-bus have significant level of 5 %, which indicates the reflection of user' heterogeneity.

Image-based three dimensional radiation treatment planning(3D RTP) has a potential of generating superior treatment plans. Advances in computer technology and software developments quickly make 3D RTP a feasible choice for routine clinical use. However, it has become clear that evaluation of a 3D plan is more difficult than a 2D plan. A number of tools has been developed to facilitate evaluation of 3D RTP both qualitatively and quantitatively. For example, beam's eye view(BEV) is one of the most powerful and time-saving method as a qualitative tool. Dose-volume histogram(DVH) has been proven to be one of the most valuable method for a quantitative tool. But it has a limitation to evaluate several different plans for biological effects of the tissue and critical organ. Therefore. there is a strong interest in developing quantitative models which would predict the likely biological response of irradiated organs and tissues. such as tumor control probability(TCP) and normal tissue complication probability(NTCP). DVH and NTCP of hepatoma were evaluated for three dimensional conformal radiotherapy(3D CRT). Also, 3D RTP was analysed as a dose optimization based on beam arrangement and beam modulation. The value of NTCP in patients with hepatitis was higher than that in patients without hepatitis. Also the value of n =0.32(volume factor) was highly correlated to prediction of radiation hepatitis. Therefore, we concluded that the possibility of radiation hepatitis was highly suggested if NTCP was over 40%.

This thesis studies on the development of transportation mode change model by the stated preference(SP) data analysis when the subway as a new traffic mode is introduced. The results of this study are as follow; 1.The results of SP data analyses for the subway operating conditions. Show that people most prefer to about 10 minute walking distance from their places to subway station, about 5 minute waiting time for next subway service, about 61 to 80 percentage of the reduction of travel-time, and about 600 won for the service fare. 2.The analyses of equivalent time coefficient for the traffic modes(as the value of equivalent time coefficient of bus is 1.00) showed that car, taxi, subway, walking, waiting, and single transfer have equivalent time coefficient of 0.75, 0.81, 0.83, 2.33, 1.71, and 14.98, respectively. These results indicate that there exist an apparent difference on an effort due to the traffic modes. The results of the analyses of value of time should that the male and female have a different value of time(13.75 won/minute and 10.75 won/minute, respectively) and people from 35 to 44 years old have the highest value of time(14.03 won/minute) among the different age groups. 3.The results of travel mode-change models to the subway by the present traffic modes. Travel mode-change models prepared in this study were established by the application of binary logit model based on generalized time. The results of the statistical examination of each parameter used in these models were significant. In addition, the value of likelihood ratio index(ρ2) of the models were stable(0.303 and 0.247 for bus and car, respectively) and the models yielded relatively high hit ratio(78.8% and 75.6% for bus and car, respectively).
