In the early decades of this century, Charisma which originally means endowment with the gift of grace, has been introduced to social sciences by German sociologist, Max Weber. It quickly became interested in the field of sociology and politics. But, into the 1970s, charismatic leadership still had not became a subject for empirical or experimental research related to organizational theory. Recently, much attention has been paid to charismatic leadership as the prototype of leadership that people have in mind when they describe their ideal leader and is more likely to provide a role model with which subordinates want to identify. As a result, in will perform further study related to Charisma leadership which developing various kind of measurement and instrument. Finally, it should identify lost of possibility and phenomenon through the study of charisma leadership.

This study was attempted to analyze the existing enticing system in teaching profession and research some idears for the devices of enticing excellent teachers. To active the above purpose, the methods of research was Herzberg's hypotheses on his motivation-hygiene theory. In Herzberg's hypothes, satisfiers and dissatisfiers are mutually exclusive. He should confirm that if we motivate teachers by satisfiers, teachers would work hard. And professor Chu supports the Herzberg Hypothes. He confirmed that satisfaction factors of teacher were related to work itself and dissatisfaction factors were realeted to the contitions or work environment. He could generalize Herzberg theory in all teachers in Seoul, Korea, without difference of teachers' subgroups. Finally, in order to entice excellent teachers, it is necessary that we must introduce the Herzberg-Theory.

Recently, GPS-aided aerial triangulation becomes a standard technique for topographic mapping. The main reason for wide spreading of combined bundle adjustment with GPS is the cost savings through considerably reduction of ground control points without loss of accuracy in comparison with conventional method. Another advantage of GPS-Photogrammetry is the real time flight navigation which enables to conduct the preplanned overlap and exposure time exactly. The combined bundle block adjustment with projection center coordinates determined by kinematic DGPS-positioning has reached a high level of accuracy. Standard deviations of the ground coordinates of ±10cm or even better can be reached. On this accuracy level also smaller error components are becoming more important. One major point of this is the interpolation of the projection centers as a function of time between the GPS-antenna locations. As a result of introducing DGPS-data into the block adjustment instead of ground control points, with only the control points located at both ends of blocks, it was possible to get same levels of accuracy as that of conventional block adjustment that needs a few control points. In case that the geometry of block is good, with one control point or without control points it was possible to adjust, but at least four control points were necessary to correct the errors remained in the kinematic positions effectively.

This study was conducted on 367 male workers to evaluate the change of vibration perception threshold(VPT) according to exposure degree to carbon disulfide. VPT was measured on both metacarpal bones of index and little fingers and on fibular malleoli by Vibrometer(Rion, on 125Hz). The exposure degree was classified by the name of department. Workers in department 2 had been exposed to carbon disulfide, those in department 3 had been exposed to undetectable concentration of carbon disulfide. The results were as follows: 1. The mean values of VDT of metacarpal(MC) bones showed dose-response pattern, i.e., the mean values of VPT at department 1 were highest, and those of VPT at department 3 were lowest with similar work duration or age. But the mean values of VPT of fibular malleoli(FM) showed dose-response patter only in workers having above 5 years of work duration or whose age were above 30. 2. The mean values of VPT of MC bone of workers increased by age. 3. There were statistically significant difference in mean values of VPT of MC bone only in workers having 5-10 year work duration. And there were statistically significant difference of mean values of VPT of left 2nd and 5th MC bone in workers whose age was 30's, of right 2nd MC bone in those whose age was 40's, and of left 2nd MC bone in those whose age was 50's. 4. The variables affecting VPT significantly were department and age(or age group) both in multiple regression and general linear model. The department showed to have more effect to VPT than age in multiple regression, but age group showed to have more effect to VPT than department in general linear model. 5. The variables were transformed to indicator variable to do logistic regression analysis. department 1, 2, 3 were classified into high exposure(spinning department) and low duration was classified into long(above 10 years) and short. The exposure and age were significant variables by logistic regression analysis. Odds rations of department and VPT on metacarpal bones or malleoli were 2.7-3.2 and VPT those were 2.6 or 2.7. Odds ratio of age and abnormality of VPT on any point was 3.3(1.59-6.8), and that of department and VPT was 2.8(1.5-5.5). We concluded that exposure of carbon disulfied was significantly associated with reduction of VPT regardless of age; and that the test of VPT would be useful tool for screening and early detection in neuropathy by carbon disulfide or other neurotoxic chemicals, even though it is simple and cheap.

The activated sludge characteristics orignated from the dye wastewater and the tar wastewater were estimated by the comparison of the flux theory with the operating diagram method. The surface areas of the setting tank of the dye wastewater calculated by both methods were almost equal and the similar results obtained on the tar wastewater. But it was found that the flux theory is not suitable for designing the setting tank, because the activated sludge settling characterisitics could be changed daily and the batch settling tests are time-consuming and labor-intensive. The emperical equation, Vi=V。·?? for the operating diagram proposed by G.T. Daigger and R.E. Roper, Jr was applied to the bye wastewater and the tar wastewater. The emperical parameters, V。, determined on the dye wastewater and the tar wastewater were 7.75m/h and 7.48m/h, respectively. The other emperical parameters, k, also estimated on the dye wastewater and the tar wasterwater were 0.00216(SVI) + 0.106 and 0.00157(SVI) + 0.157, respectvely. Consequently, the following relationships between SVI and sludge settling characteristics of the dye wastewater and the tar wastewater were determined ; dye wastewater ; Vi = 7.75e {-0.00216(SVI) + 0.106)?? tar wastewater ; Vi = 7.75e {-0.00157(SVI) + 0.157)??

The guarantee of transaction stability, the convenience of using the system, an supply of all kinds of goods and the differentiated service strategy for customers are needed in order to attract more customers in electronic stores. In this paper, we propose a differentiated service strategy for customers that can supply the better information about goods for the customers by evaluating the closeness between goods. If the customers visit the shopping mall for EC, the proposed method supplies such information about goods as consistent with the customers' favorite by employing the customers' preference that is managed separately for each customer. The proposed approach as like the above can enhance the satisfaction of customers and result in the steady visit of them
