This paper presents a GA-based optimal algorithm for a resource leveling model that levels the resources of a set of non-critical activities experiencing conflicts simultaneously up to an assumed level of resource rates specified by the planner using a pair-wise comparison of the activities being considered. A parameter called the future float is adopted and applied as an indicator for assigning leveling priorities to the sets of activities experiencing conflicts. A construction project network example was worked out to demonstrate the performance of the proposed method. The histogram obtained using the algorithm proposed was shown to be the same as, or very close to that produced by the existing resource leveling method based on the least total float rule, which shifts non-critical activities individually.

Purpose : The study was to promote patient safety by analyzing the effect of dental hygienist's perception of patient safety culture on infection control activities. Methods : The study is based on a survey of 210 dental hygienists in total working in dental settings. To find out infection control activities according to patient safety culture awareness, there were 6 general characteristics, 3 teamwork within the department, 2 infection control systems, 4 surface management, 9 equipment washing, disinfection, and laundry management, 4 infectious wastes, and 3 personal protection phrases.The data was analyzed using the SPSS version 20.0, and p<.05 was adopted to decide on significance. Results : The longer dental hygienists have worked n the dental settings, the more active they become in infection control activities. Among the different types of dental care settings, general (university) hospitals had the largest number of infection control activities, followed by dental clinics, and network dental clinics, in descending order. The dental settings possessing a higher number of dental hygienists were found to conduct more infection control activities than other dental settings. In addition, it was found that when a dental setting adopts a patient safety policy across all the units in the hospital, more systems and procedures for patient safety tend to be established, and that stricter management response to error leads to improvement of infection control activities. Conclusion :In order to enhance infection control activities, infection control activity programs should develop and implement periodic reinforcement of infection control education. regular monitoring of infection control activities.

This paper argues that there are circulative linkages between knowledge creation, sharing and utilization in innovative clusters. Based upon discussion about characteristics of circulative linkages between three types of knowledge activities, this paper presents three hypotheses: the more regions generate knowledge, the more active they share knowledge (hypothesis I); the more regions share knowledge, the more vigorous they utilize knowledge (hypothesis II) and the more regions generate knowledge, the more vigorous they utilize knowledge (hypothesis III). Empirical analysis into the Korean case turned out that hypotheses I and III were strongly supported, but hypothesis II weakly supported, probably due to inaccurate proxies for knowledge activities. This study may help guide provincial governments to choose policy goals to promote knowledge activities. It also leads to the conclusion that maintaining balance among three types of knowledge activities (creation, sharing and utilization) is a way of their policy making for the promotion of innovative clusters.

The purpose of this study is to identify the situation of leisure preferences, the effect of related variables on the leisure preferences, and the relationship between leisure preferences and participations of urban married women. The survey of this research was conducted by means of interviews with 606 married women in Seoul. The instruments of the survey were questionnaires including a leisure preferences scale. Data were analysed by means of the statistics of frequency, mean, standard deviation, ANOVA, and Sheffe’s multiple range test, using the SPSS program. The results were as follows: The most preferred leisure type by urban married women is family oriented activities, especially conversations with family and playing with children. The level of leisure preferences differs according to related variables. The most distinctive variable on leisure preferences is the sex role of women. The relationship between leisure preferences and participations differs according to leisure activities and types. Especially in the area of religion/ social activities and self-developing activities, preferences on leisure activities has relatively strong relationship with participations on leisure activities.

A construction process consists of value adding activities and non-value adding activities, necessary or unnecessary. If construction personnel can eliminate inefficient and/or unnecessary activities within the process, they may have a great opportunity to improve their construction process. The Product Process Analysis (PPA) technique, which was developed in the manufacturing industry, can be applied for identifying wastes in the construction process and ultimately improving the process itself. It provides useful tools, such as a process chart worksheet and flow diagram, for mapping the flow of construction activities with predetermined standardized symbols. These tools make people understand the flow of activities more easily, identify value adding/non-value adding activities within the process, and areas where the process can be improved. The example applications of PPA are demonstrated in the paper through the case studies implemented on the construction process of structural steel. The results of case studies indicate that PPA technique was effective at identifying and removing wastes in the steel construction process. It is also found that PPA technique is more effective for improving highly repetitive construction processes.

The purposes of this study were to analyze the types of leisure activities and level of leisure satisfaction with practice of a five-day workweek, and examined the relationship between leisure satisfaction and job satisfaction. The data were based on the questionnaire with 264 working employee residing in Seoul. The results indicated that the most frequently participating activities were sports, use of media, loaming activities in order. And there were no significant differences in types of leisure activities between 5 day working employees and 6 day working employees. Secondly, general level of leisure satisfaction was the highest when participating religious activities. Thirdly, it was found that only social satisfaction was positively related to job satisfaction, and social satisfaction influenced job satisfaction. Further discussions and implications were discussed.

This study analyzes the impacts of household work participation and shared activities between couples on marital relationship and depression among retired men and women with retired husbands. To investigate this, a survey of 367 married people is conducted on retired men and women with retired husbands. The influencing factors on the marital relationship of retired men are found to be couples' shared activities, gender role attitudes, and subjective health status. The marital relationship of women with retired husbands is influenced by shared activities by couples, the division of domestic labor, and gender role attitudes. The factors affecting retired men's depression are shared activities by couples, perceived health status, type of jobs before retirement, and age. Women's depression is related to household income, shared activities by couples, husbands' jobs before retirement, subjective health status, and division of household labor.

Objectives: This study analyzes whether the leisure activities satisfaction of elderly and older elderly patients differs with population sociology characteristics for the leisure activities services provided by geriatric hospitals, and to provide basic information to make reasonable decisions. Methods: Difference Analysis of the difference (T-test, ANOVA) in leisure activities satisfaction was conducted for the elderly and older elderly patients hospitalized in nine hospitals. Results: First, In the planning stage of leisure activity program, it is necessary to consider the tendency of men and women to prefer gender-based leisure activity service. Second, It was found that old elderly patients were more in number than elderly patients. Third, managers of geriatric hospitals in Busan and Kyungnam area should consider the needs of the patients in the planning and implementation of leisure activities and improve their leisure activity programs or develop more programs for better customer satisfaction.

The effective management of knowledge has become one of the critical success factors in current organizations. In spite of the extensive use of Knowledge Management System (KMS), useful information and knowledge resources are still transmitted through personal networks among people in organizations. Thus, social network theory which focuses on social relationships in organization can be a fruitful theoretical resource for enhancing Knowledge Management (KM) performances. In this study, we investigate the effects of intra-team network characteristics (i.e., group density and degree of centralization) and external boundary spanning activities on knowledge management performances of a team. We also acknowledge that all group members do not necessarily agree on the team goal and actively disseminate useful information and knowledge. Drawing on the political perspective on KM which emphasizes the role of trust among group members, we examine the mediating effects of team trust between internal/external network characteristics and KM performances. From the data of 220 teams in financial companies in Korea, we found that: (1) group density had positive effects on KM performances (i.e., knowledge creation, sharing, and use). (2) However, centralization was not significantly associated with KM performances. (3) Team trust was found to be an important factor mediating the relationship between intra-team network characteristics, boundary spanning activities, and KM performances. Based on these results, we discuss and suggest possible implications of the findings when designing and implementing KM practices.
