  • For decades, the productivity issue has been a primary concern for the all stake-holders who participate in domestic construction industry. Especially, between a whole life cycle of building, the construction phase's productivity problem makes or break the entire project. In this respect, the general construction company, who accept the order and construct the building(so called General Contractor), should consider various strategies, such as schedule management, cost management, quality management, inner-crew management, etc., for the productivity improvement., and almost of these management methods have been studied for a long time. But, the researches and studies about the specialty contractor, who construct the building directly in construction site were not sufficiently complete yet. This research begins as an idea which tries to apply the BIM(Building Information Modeling) into the tasks of Specialty contractors for their productivity improvement. And for the effective application of construction BIM to specialty contractors, establish of the BIM project execution plan for them, not the fragmentary adoption of BIM. Therefore, in this paper, we develop the BIM project execution plan for the reinforced concrete companies who conduct the framework construction which located on CP(Critical Path) Especially, we model the "Construction BIM Use List for the RC Work", "BIM Application Master Process" and "BIM Application Detailed Process", and general contractor who use these BIM uses list and process models can manage various specialty contractors about schedule, cost, earned value, quality, safety and environment management systematically.

  • Purpose: This study was conducted to determine the effects of Tai-Chi exercise and self-help management program applying laughter therapy in patients with osteoarthritis. Methods: This quasi-experimental study recruited a sample of 61 patients with osteoarthritis (experimental group: 30, control group: 31) through the community healthcare centers located in Seoul and Kyung Gi area. The primary outcome measures included symptoms of osteoarthritis, basic physical performance, fatigue, and depression assessed before and after the study. The data were analyzed using SPSSWIN V. 12.0. Results: At the end of the six-week intervention, left shoulder flexibility (t=2.011, p=.049), 6m walking speed (t=3.639, p=.001), and right balance (t=-2.30, p=.025) were significantly improved in the control group. Fatigue (t=3.012, p=.004), stiffness (t=2,093, p=.041), right shoulder flexibility (t=2.138, p=.037), right balance (t=-2.065, p=.043), and 6m walking speed (t=2.683, p=.009) were significantly improved in the experimental group. Conclusion: A twice a week, 6-week tai-chi exercise self-help management program applying laughter therapy is effective in decreasing fatigue and stiffness. Osteoarthritis is one of common chronic diseases that the patients should be required to continue self management for the rest of their life. Therefore, there is a need to develop the more effective self-help management program and nursing intervention to motivate them to maintain their own self-help management.

  • This study was conducted to identify the job stress factors of school foodservice employees and to examine the relationship between job stress and turnover intention through path analysis. Data was collected using a survey of 432 school foodservice employees in elementary and secondary schools in Masan, Kyungsangnam-do. All of the participants were female, and 165(52.9%) were over the age of 45' Additionally, 310(99.4%) of the respondents were married, while 287(92.0%) had less than a high school level of education. Furthermore, 271(86.9%) of the respondents were cooks. Overall, 107(34.3%) of the respondents had worked in the food industry for less than $5{\sim}10$ years. In addition, 208 (66.7%) respondents answered that they had 'never' changed jobs. Among job characteristics that causes job stress, job posture was the primary stress factor, followed by heavy work load and job condition. Job stress was found to be significantly correlated with turnover intention. Additionally, job position was the only moderating variable that was found to be correlated with job characteristics and job stress. Finally, the moderating variables influencing the effects of job stress on turnover intention were identified as performance confidence, job career, and job position. The results of this study will be useful for future studies conducted to evaluate the development of job environments and performance to minimize turnover and job inefficiency as a result of job stress.

  • The purpose of this study is to interpret Landscape of Naeap Village which still preserves the Confucian culture and the traditional clans among the ideally settled villages mentioned in Joong Hwan Lee's "Taengniji" and "Joseon's Fengsui" from the time of Japanese Imperial Rule, from CPTED principles. The following are the findings of this study: First, in terms of access control and zoning, Naeap Village was controlling access from the outside with the natural environment of Banbyeoncheon River and the hills surrounding the village, the artificial environment of human-scale walls around the head house and the dead ends, and the reformation by the Confucian ideologies. Naeap Village, in particular, is prominently configured by the hierarchy of zones; the Gaehosong pine trees, Gyeongpodae, and Naeapssu by the entrance to the village are considered the village itself and the landscapes and valleys are managed by the head house. Second, the Confucian culture across the village, the traditional vegetation method that does not hide the visibility, and the workers in the farms allow natural monitoring. The surrounding visibility is also applied to the spirit of mutual cooperation in the farming society, the culture of commoners at the common well and laundry site, and the culture of ruling class at the towers and pavilions. Third, Traditional villages show the efforts to preserve and maintain the villages with the village rules, the organizational decrees of the clan, and active response to national disasters.

  • To improve the gear noise quality, gear tooth grinding machine are widely used in automotive industry. While using the gear profile grinding machine to improve the gear tooth quality of the transmission, several defects such as chattering, tooth waves that cause the gear noise occasionally happened. But it is very difficult to solve that problem, because there is no one who knows the setting up the optimal grinding condition appropriately. The abnormal manufacturing conditions which make the gear noise make the engineer to spend a lot of time, effort, and money. Due to demands for solving the serious abnormal gear noise happened in the new FF 6th stage automatic transmission in the mass product stage, the vibration checking process in the worm wheel axis, work rotation and fixed axis of the grinding machine were adapted to find the root causes. As a result, gear profile wave are affected by the work rotation axis's unbalance which is caused by worm wheel feeding speed. And a primary and the secondary grinding feeding speed, cutting oil, work fixed forces are also proved as the important factors. After setting up the grinding condition reported in this paper, it was adapted successfully to the grinding machine to manufacture the new FF 6th speed automatic transmissions' output gear. The gear noise was dramatically disappeared and the process and results will offer good guides to the engineers who manufacture the gear with the grinding machine.

  • In this study, I examined the psychological visual effect and clothes preference by clothes designs for the mid-aged Korean and American women's somatotypes. The psychological visual effects of each somatotypes' clothes are like these. First, the primary factors for psychological visual effect were analyzed into 5, neat, feminine, polished, modern and active. Second, in thin somatotype, Korean evaluated that china collar and V-neckline are the least feminine, and stand collar is the most polished and the modernest. American evaluated that V-neckline is the most feminine, and tailored collar is the modernest. It shows that there's the difference of culture. In standard somatotype, Korean thought stand collar with pants is the neatest, but tailored collar and china collar with pants are not neat. Contrary, they thought tailored collar with skirt is the neatest and stand collar with skirt is not neat. American thought tailored collar with skirt is the neatest and modernest. The neat visual effects are evaluated differently according to the clothes' styles of bottom. In obesity, Korean evaluated that tailored collar with skirt is the neatest and modernest, but stand collar with skirt is not modern. Stand collar with pants is the modernest, but tailored collar with pants is the least modern and active. American evaluated that round neckline with pants is not neat, modern and active, and round neckline with skirt is the modernest and the most active. So neckline's visual effects are differently showed by culture and the clothes' styles of bottom.

  • Discomfort as well as muscular pain and musculoskeletal diseases occur in cases of stressed posture due to prolonged pressure. Therefore, the American Academy of Orthopaedic Surgeons (AAOS) and Pediatric Orthopaedic Society of North America (POSNA) recommend that bags that weigh no more than 15 - 20% of the wearer's weight. However, despite the prolonged pressure from using baby carriers, there are no recommendations and limited studies on how to protect wearers. Therefore, this study investigates subjective fatigue according to the usage of waist support and hip seat. Based on this, muscle fatigue and secondary subjective fatigue according to three types of currently commercial baby carriers (X-type, H-type, and H-hip type) were measured. Subjective comfortability was evaluated on a 5 point Likert-scale and subjective fatigue was evaluated on Borg's CR-10 scale. Objective muscle fatigue was also compared by measuring and analyzing electromyogram (EMG). The results of primary subjective fatigue showed statistically significant changes in the shoulders, waist, calves, and soles of the feet according to the usage of hip seats and waist support. Electromyogram measurements also showed less muscle fatigue at the upper trapezius muscle and thoracic erector spine muscle for the H-hip seat baby carrier, which has both waist support and hip seat, compared to an X-type baby carrier, which has neither. However, results of subjective fatigue showed opposite results at the waist despite having same results at the shoulders and beneath the shoulders. This show discrepancies between objective muscle fatigue and subjective fatigue; therefore, that both aspects must be taken into consideration when developing ergonomic baby carriers.

  • This study systematically identified the influence of the school look fashion image on public culture, which is used for increasingly sexualized marketing appeal by domestic Girl Groups. We examined and analyzed the school look fashion image of Girl Groups, focusing on the Lolita complex which is particularly influential in the sexual appeal of domestic popular fashion. The method of this study is based on a literature review from the years 2007 to 2016, when the female girl groups began to receive attention. The music videos of the female girl groups in the top 100 charts of 'Melon' from 2006 to 2-16, which provides the largest mobile music service in Korea, were watched and analyzed as primary data. As a result, it was found that the 'school fashion look image' of adolescence which was used as costumes for Girl Groups, plays a role in commercializing the image of a 'girl', and the types and characteristics of school look fashion image are drawn in two ways. First, it is the image of a seductive Lolita complex. This is the case where young girls wear school look fashion image to emphasize their sexual maturity. Second, it is the case that is using the school look fashion image in order to perform with the 'young girl' concept, as an image of the enchanting Lolita complex; in addition, the erotic body image is more explicitly exposed through choreography and nakedness.
