This paper illustrates the pragram features of reliability evaluation on operation mode (operational planning and operating) of power system. The eighty eight relative reports and papers with seventeen kinds of reliability programs were Investigated in this paper. Two programs, PRA and ASSESS, were focused on the operation mode reliability evaluation program and the comparions of the two program features are introduced.

The purpose of this study was to examine impact of hospital computerization on the nursing practice. The study was conducted using the repeated measured design. The subjects were 166 nurses working at surgical nursing care units in a tertiary teaching hospital. A questionnaire was developed based on the Burke's study, and reviewed by a committee for content validity. Eighty-eight nurses responded the questionnaire throughout the study. Indirect nursing care time significantly decreased(p<0.05) after the computerization. These decrease related to time saving in checking physicians' order and writing nursing records. However, the change in direct nursing care time was not clear. In conclusion, the computerization led to the decrease in indirect nursing care time but it did not link to increase in direct nursing care time. Therefore, nurse managers should take into account redesign of the nursing works after computerization.

Eighty-nine patients with mandibular fracture were treated by open reduction and internal fixation using the monocortical titanium miniplate(Leibinger Co.). Postsurgical intermaxillary fixation was carried out for 2 to 18 days according to the patient's status. Seven patients developed infections postoperatively(7.9%). Five patients were favorably treated by incision and drainage and/or saucerization. But two patients were not controlled by early surgical intervention and should have been followed by plate removal, saucerization and secondary reconstruction including the bone graft. This article reports the postoperative infection associated with miniplate fixation of mandibular fractures and discuss the incidence, cause, treatment and prognosis with careful case analyses.

Maxillary sinusitis is an infectious disease which can arise from odontogenic etiology and a maxillary osteomyelitis can spread into the sinus and consequently develop maxillary sinusitis. In this case report, a mid eighty's lady was diagnosed as BRONJ with maxillary sinusitis as a complication. The patient was managed successfully in collaboration with a endocrinologist. Through serial follow-up of serum CTX, we could decide the timing of surgical intervention.

This study investigated the influence of peer friendliness, conflict, and collaboration on children's problem solving performance. Eighty-two preschool children (41 pairs) filled out the Friendship Assessment Inventory and participated in 3 problem-solving sessions using the Tower of Hanoi. Results showed that just working together does not improve children's problem solving performance. The degree of friendliness children have for each other has a significant effect on their problem solving performance. The children who worked with more friendly peers were more collaborative and were better problem solvers than those who worked with less friendly peers. This study suggests the importance of the relationship between interacting peers on problem solving performance.

The relationship between thermal decomposition temperature and structure of a new data set of eighty monomers of different polymers were studied by multiple linear regression (MLR). The stepwise method was used in order to variable selection. The best descriptors were selected from over 1400 descriptors including; topological, geometrical, electronic and hybrid descriptors. The effect of number of descriptors on the correlation coefficient (R) and F-ratio were considered. Two models were suggested, one model having four descriptors ($R^2$ = 0.894, $Q^2_{cv}$ = 0.900, F = 172.1) and other model involving 13 descriptors ($R^2$ = 0.956, $Q^2_{cv}$ = 0.956, F = 125.4).

This study investigated the factors in evaluating internet shopping mall sites, and developed a self-report evaluation scale of such sites, This article identifies factors to determine criteria for evaluating the sites from the consumers' viewpoint. Eighty three items were extracted initially, which were then categorized as follows: \circled1 Type of business, \circled2 Navigation ease, \circled3 Technological level, \circled4 Design of sites, \circled5 Communication ease, \circled6 Information available, \circled7 Ease of access, and \circled8 Site security, Overall reliability coefficients were high in the individual domains ($\alpha$=.86 to $\alpha$=.95). Face validity and contents validity were demonstrated to be good, There were significant differences in the means of these categories. The results also show that the technological level is the most important in shopping mall sites evaluation. These results may be used not only as a tool to evaluate shopping mall sites but also as a guideline to improve the quality of a shopping mall site that is under development.

One hundred and eighty-seven water samples were collected from 23 of spring water, 2 of ground water, 1 of tap water in Pusan area and 3 of natural mineral waters. Total coliform group, fecal coliform, viable cell count and microflora were investigated to evaluate water quality of drinking water. The results were as follows: range and geometric mean value of total coliform and fecal coliform MPN's of spring water were 0~1,500/100 ml, 85/100 ml and 0~460/100 ml, 24/100 ml but coliform group was not detected in the samples of tap water and natural mineral water. Viable cell count of spring water, ground water and tap water were lower as 100 cell than the criteria for drinking water but that of natural mineral water was higher as 6.5X 10$^2$~7.4X 10$^3$ /ml. Predominant speces among the 219 strains isolated from the samples were 19.6% Aeromonas spp., 19.2% Enterobacteriaceae, 16% Acinetobacter spp. Especially, spring water and vessels were contaminated by Hafnia spp. and Providencia Spp, inhabitant of the oral cavity.

The purpose of this study was to investigate actual trends of young children's video and computer-based game uses. Four hundred and eighty parents of 4-6 year-old children were questioned about children's game uses and their attitude toward them and 180 of their children were interviewed. As the results of this study, most of children have been playing video and computer games. Boys played them more frequently than girls and the olders than the youngers. The majority of children liked video and computer games. The first reason to play games was 'interesting'. The most parents considerably tolerated to their children playing games except the arcade games. Many parents limited their children's time of playing games. They occasionally played with their children or observed them playing games.

This paper examines the international commerce expert capability and business performance in global supply chain management. Based on the analysis of eighty-seven cases, the following results were found. First it was found that CEO's capability of global supply chain management firms and business performance are significantly correlated. Second, supply chain management manager's capability of global supply chain management firms and business performance are not significantly correlated. Third, CEO's capability have more a positive influence business performance than supply chain management manager's capability in global supply chain management firms.
