  • Mathematics is extreme the differences of the scholarly attainments in comparison with other subjects at a middle school. Specially, the students at islands and places leave much to be desired the scholarly attainments standards of mathematics. Therefore, every school takes movement class according to level these days. And the small schools put in effect the cooperation of group work through the small groups. These classes are effective at the scholarly attainments extension to some degree, but each student is extreme the differences of scholarly attainments. On this, the small school was the subject of study at the present research and put in effect the cooperation of group work through the small groups. The students were divided in three groups; the top class, average, the low class, And they were offered the fitting textbooks matching the cooperation of group work and the opportunities of discovery learning fitting an individual ability and standard. Consequently, some educational materials were made, for example, question papers, commonness learning materials, choice learning materials. These materials were put in effect to the students to be able to succeed discovery learning. With this, the students were investigated an interest of mathematics and the influence giving at the studies attainment. And the students were put in effect the cooperation of group work through the small groups to improve uniformity and sturdiness of the mathematical education. The conclusion at the present research is as follows. 1) When the students put in effect the cooperation of group work through the small groups, the scholarly attainments of mathematics totally didn't display useful changes as improvement. However, the students of average and the low class gradually seemed to improve the scholarly attainments of mathematics as the help of the top class positively. 2) An individual and cooperation learning in the method of the cooperation of group work through the small groups displayed many changes at the learning attitude of the students by means of discovery learning thanks to the learning heads. 3) When the investigator put in effect the cooperation of group work through rather the small groups than the large groups, the numbers of the students experiencing interest about mathematics increased in 26% and this learning method should continue to progress.

  • Background: The concept of social capital has its focus on cooperative relations in the workplace. This study investigates the association between social capital and sickness absence among workers in 41 work groups in the Danish dairy industry and examines the possible effects of an intervention on social capital in the workplace on sickness absence. Methods: A sample of 791 dairy workers working in 41 work groups that participated in an intervention study on social capital filled in a questionnaire on four subtypes of social capital, and social capital scores from individual participants were aggregated to the level of work groups. Sickness absence was measured at the level of work groups in company registers as the two-year average percentage of working time lost to sickness absence. Group-level associations between social capital and sickness absence were analyzed using multilevel linear regression analysis. Analyses were adjusted for age, gender, group size, and random effects at the workplace level. Results: We found statistically significant associations between social capital within work groups, social capital in relation to the immediate manager, and social capital toward the workplace as a whole on the one side and sickness absence on the other side. We found no support for any effects of the intervention on sickness absence. Conclusion: The work group level of social capital is associated with the work group level of sickness absence. However, the intervention to enhance group-level social capital had no effect on reducing sickness absence in the intervention group.

  • Through smart work using by smart technologies, many organizations wish to change traditional working styles. Lots of organizations, however, wish to do work with smartness through adoption of smart work technologies, those are not sure whether smart work will be successful or not till now. Viewpoints of members concerning efficiency and effectiveness from smart work who operate the organizations may be different. Therefore, hopefully, this research tried to investigate whether differences among members of organizations by empirical and exploratory approach. Totally, 118 questionnaires had been collected and performed test of mean difference between groups. As a result, some items such as working place, working methods, flexible time and tension of smartwork showed significant differences among groups and non-leader and leader groups. And, furthermore, from this research I believe that we can have a few insights for successful smart working environment in organizations. For successful smart work, organizations have to try to overcome or minimize differences among members of organization.

  • This study conducted a comparative analysis of awareness level of review standards, continuing education, and awareness about the need for speciality and educational courses in order to improve quality of Korean health insurance review work and to present directions for policies of personnel development and continuing education to smoothly perform hospital's insurance claim work and Agency's review work. The analysis unit of the study is individuals, and survey was conducted among hospital's claim officers and Agency' review officers by distributing questionnaires. The major results of the study are as follows: First, it is found that hospital's claim officers and Agency's review officers have conflicting awareness about review standards; more Agency's review officers think that current review standards are universal and reasonable, while more hospital's claim officers believe that they need to be revised. Especially, hospital's claim officers replied that it is possible that review results can differ according to government's policies. Second, there is no significant difference between the two groups in the opinion that there are individual differences in awareness level of review standard. In particular, both groups share the opinion that review results can differ according to officer's interpretation of review standards. Third, Both review officer groups feel the need for further training and continuing education. Fourth, there is no difference between the two groups in the opinion that both groups members should be educated in review related educational institutions. However, while 81.5% of Agency's review officers the education should be offered at the Agency, only 45.2% of hospital's claim officers agreed to it. Fifth, both review personnel do not show any difference in awareness of needed experience to successfully perform review work; both groups replied that three to four years experience is necessary to smoothly perform claim work and review work. This study was tried in order to search for directions to improve Korean insurance review work in quality rather than to explore characteristics themselves of individual factors. In this sense, this study presupposed an intention that the educational subjects for further training and continuing education for the two groups should be the same in order to narrow the awareness gap between hospital's claim officers and Agency's review officers. Thus, this study suggests that it is desirable to offer beginner courses at junior colleges or in undergraduate courses and advanced courses in professional graduate school for six to twelve months. In that a comparison of awareness level of hospital's claim officers and Agency's review officers who are actually in practice should precede appropriate presentation of directions for the qualitative improvement of insurance review work in Korea, the significance of this study lies in comparatively analyzing the awareness level of hospital's claim officers and Agency's review officers and in presenting the establishment of future further training and continuing education.

  • A flexible flow line(FFL) consists of several groups of identical machines. All work-orders flow along the same path through successive machine groups. Thus, we emphasized the balancing of workloads between machine groups in order to maximize total productivity. On the other hand, many different types of work-orders, in varying batch or lot sizes, are produced simultaneously. The mix of work-orders, their lot sizes, and the sequence in which they are produced affect the amount of workload. However, the work-orders and their lot sizes are prefixed and cannot be changed. Because of these reasons, we have developed an optimal route selection model using heuristic search and Min-Max algorithm for balancing the workload between machine groups in the FFL.

  • The purpose of present study is to examine the relative efficacy of active exercise programs for work-related chronic low back pain and to figure out how much they affect mechanical stability of lumbar. Subjects are 43 employees with work-related chronic low hack pain, and they were randomly divided into two groups with general physiotherapy groups and thoracic exercise groups for increasing thoracic mobility. Active exercise programs were done 3 times a week, for 6 months, and the subjects were tested for Pain intensity(VAS), the Oswestry Disability Index, Maximal stretching with both hands in the overhead direction and the lumbar region angle of inclination. All subjects were reassessed with same measurement with Pre-study and 6 months after study After applying active exercise programs, pain intensity didn't show any significant difference between two groups. The Oswestry Disability Index showed significant difference between two groups and thoracic exercise groups decreased significantly compare to general physiotherapy group(p<0.05). Maximal stretching with both hands in the overhead direction showed significant difference between two groups and thoracic exercise group increased significantly more than general physiotherapy groups(p<0.05). The lumbar region angle of inclination showed significant difference between two groups and thoracic exercise group decreased significantly more than general physiotherapy groups (p<0.05). According to the results above, exercise for increasing thoracic mobility has an effect on lumbar stability. For the work-related chronic lower hack pain workers, it is far more effective for lumbar stabilization than general physiotherapy.

  • The purpose of this study is to analyze the present condition of work-leisure balance and its influencing factors in employed young single households. Three groups of sample households-work-oriented, balanced, and leisure-oriented-were compared by factors related to work and leisure. Six cases were interviewed to obtain qualitative data on the subjective meaning of work-life balance and its influencing factors. The results showed different characteristics between the three groups based on the various work- and -leisure- related factors: average weekly working hours of the week, number of vacation days per year, weekday leisure time, degree of weekday freedom, and sufficiency of the leisure cost. In addition, the characteristics considered desirable for quality of life differed between groups. Finding the meaning of life through work and leisure was very important for those respondents, who have an unstable position in the labor market, and who want to delay making decisions on moving into the marriage and family-building phase recognized as a major development task for Korean adults.

  • The aim of this study is to investigate the efficacy of pair/group work on the improvement of receptive and productive vocabulary knowledge. One hundred and twelve university students participated in the study and they were divided into three groups. Pair work group(n=42) performed three vocabulary activities in pairs as extra-class works, and Individual work group(n=38) did them alone. On the other hand, Group work group(n=32) did the activities in groups consisting of four or five people during the class. Data were collected from one pretest and two posttest scores. The results showed that collaborative group work was conducive to the growth of both receptive and productive vocabulary knowledge. In contrast, pair groups who do not work collaboratively gained least vocabulary knowledge among three groups. From collaborative group work, participants in higher proficiency levels made greater vocabulary gains than those at lower levels. Based on these results, pedagogical implications are discussed.
