Objective:This study is on the characteristics of motorcycle accidents occurring in the mail delivery process by skill level. Background: The tendency of delivery postmen's driving in a hurry may become the cause of accidents since there is a constraint that delivery should be completed within a limited time. Method: This study analyzed the traffic accident data of 259 delivery postmen, who had been approved as occupation-related industrial accident victims from 2009 to 2012, by their work experience in view of season, day of the week of an accident occurrence, accident occurrence time, accident cause, collision type, and driving situation. Results: Accident characteristics of delivery postmen show that the ratio of accidents occurring to those who had less than 10 years of work experience was high. There were many motorcycle collisions in winter and summer by season and an unexpected object, along with road condition, took up 70.7% of the accident sources. There were no differences in accident occurrence time, the day of the week, season, accident source, and collision type between the group of delivery postmen with less than 10 years of work experience and those with 10 years or more of work experience. However, there was a difference in distribution of driving condition. Conclusion and Applications: The results of this study can be used to present the policies or guidelines for the accident prevention of delivery postmen since the results show the characteristics of the injured and accident occurrence characteristics in relation with the delivery postmen's motorcycle collisions.

Two experiments were carried out to investigate the effect of Murrah buffalo cows pulling sledges under field conditions on milk production and milk composition. In Exp. 1, 24 buffaloes in the fourth month of lactation were used. They were allotted to four treatments according to a $2{\times}2$ factorial arrangement: work or no work, and with or without urea-molasses cake supplementation (700 g/animal/day). Feeds consisted of 20 kg fresh elephant grass (18% DM), 2 kg rice bran per day and rice straw ad lib. The animals worked in pairs three hours per day (work done: $3464{\pm}786kJ/d$) five days a week for three months. Three teams worked in the morning and the others worked in the afternoon in the same day. The following day the working times were switched. In Exp. 2, 16 lactating Murrah buffalo cows in the sixth month of lactation were allotted to two groups (work and no work). They were fed with fresh ruzi grass (Brachiaria ruziziensis) ad lib. supplemented with 2 kg rice bran and 700 g urea-molasses cake. The working regime was similar to that of the first experiment (work done: $3753{\pm}879kJ/d$) and they worked for two months. In the first experiment, there was a small but significant drop (p<0.05) in milk yield from 3.5 to 3.0 kg/day due to work, but there was no supplementation effect. The working buffaloes lost 5.2 kg whereas the non-working animals gained 9.7 kg during the three months (p<0.05). Supplementation increased live weight by 9.9 kg as compared to -5.4 kg for those not supplemented (p<0.05). Milk composition was not affected by the treatments. In the second experiment, daily milk production was similar for both treatments and approximately 3 kg. No significant differences were found in milk composition or in live weight changes for working and non-working groups, respectively. It was concluded that work may cause a reduction in milk yield and a loss of live weight on a poor rice straw diet but that an appropriate supplementation can alleviate this situation.

This study aims to express the androgynous image via shirts as a fashion item. Shirts are widely worn as a fashion item regardless of sex and age, with growing importance as a casual outer, with the increase in leisure activities driven by the recent implementation of the 5-Day Work Week system in Korea. As for the theoretical background, the study was reviewed previous studies of books, thesis, a series of publication, and the Internet sites on this topic. Through a careful analysis of these previous studies, it designed and made shirts that inspired by androgynous image. Conclusions of this study are as follows: First, the study found that meanings of symbolism in clothing continue to change, not fixed at all, depending on historic and cultural environments, and so does symbolism for femininity and masculinity of clothing. Second, shirts are widely worn as a fashion item regardless of sex and age, with growing importance as a casual outer, with the increase in leisure activities driven by the recent implementation of the 5-Day Work Week system in Korea. Third, two patters were used for the work in this study in order to emphasize its form, along with mono color white and stripe patterns. For materials, cotton and blend as a most basic material for a shirt were used with unique variations in the form. Fourth, decorative details or trimming such as ribbon tying methods, shirring, attaching in layers, and irregular pleading widely used for women's wear were applied, and silhouettes with strong drape feelings were used to add feminine feature to men' shirts, in an effort to propose a fashion design of the androgynous look. Fifth, clothes proposed in this study are different from feminine clothing item blouse, because they are androgynous shirts mixing masculinity and femininity. Stiff pads were used in collars and cuffs characteristics of men's traditional shirts to maintain masculinity of a shirt, and design was developed by adding feminine decorative elements, which is different from women's blouse.

This study investigates the influences of factors such as type and degree of family leisure among parents with five day work weeks on adolescents' perceived family strengths. Its findings are based on questionnaires collected from 525 male and female parents of middle school students. Factor analysis and MANOVA were employed for data analysis and $Scheff{\acute{e}}$ tests for post-hoc analysis. The main findings were as follows. First, adolescents whose parents work five days a week were at a higher level than other adolescents in terms of finances, family ties, communication, and social ties. Second, there were no significant differences concerning adolescents' family strength by type of family leisure. Third, adolescents with more family leisure activities scored higher than others in the areas of manageable strengths, financial levels, family ties, communication, and family social ties. Fourth, among families following the five day working system, adolescents who had more family leisure activities scored higher than the others in regards to manageable strengths, financial levels, family ties, communication, and family social ties. Additionally, where adolescents thought they had fewer family leisure activities, family-oriented adolescents tended to be engaged in higher physical-activity-oriented and hobby-oriented activities in relation to manageable strengths, financial level, family ties, and communication and hobby-oriented adolescents engaged in higher than average amounts of physical-activity, strengthening family social ties in the process. Fifth, concerning families not adhering to the five day working system, adolescents who had more family leisure activities scored higher than others in terms of manageable strengths, financial levels, family ties, communication, and family social ties. As the above results indicate, family leisure activities appear to be a key factor influencing family strength. Therefore, further support should be extended toward developing new forms of family leisure and additional studies should be devoted to the subject.

The purpose of this study is to analyze the changes in turnover intention according to the level of Burn out and the mediating effect in fire officer. Higher levels of emotional labor and turnover intention resulted in higher levels of burn out(p<0.05). We used the logistic regression analysis to compare change of turnover intention according to the level of burn out. In logistic regression analysis, largest mediating factor were working days per week, the number of moving case per a day, physical condition, emotional labor and the odds(Likely to with high turnover intention) was down by 38.9% after adjustment for mediating factors. The results of this study indicate that emotional labor was negatively impact on burn out in fire officer. To reduce the burn out and the turnover intention, it is necessary to do more efforts to improve work environment (working days per week, the number of moving case per a day and emotional labor) and management personal factor(physical condition) for the fire office should be made to reduce such negative effects.

Objectives: 1) To determine mercury levels in urine samples from garbage workers in Southern Thailand, and 2) to describe the association between work characteristics, work positions, behavioral factors, and acute symptoms; and levels of mercury in urine samples. Methods: A case-control study was conducted by interviewing 60 workers in 5 hazardous-waste-management factories, and 60 matched non-exposed persons living in the same area of Southern Thailand. Urine samples were collected to determine mercury levels by cold-vapor atomic absorption spectrometer mercury analyzer. Results: The hazardous-waste workers' urinary mercury levels (10.07 ${\mu}g/g$ creatinine) were significantly higher than the control group (1.33 ${\mu}g/g$ creatinine) (p < 0.001). Work position, duration of work, personal protective equipment (PPE), and personal hygiene, were significantly associated with urinary mercury level (p < 0.001). The workers developed acute symptoms - of head-aches, nausea, chest tightness, fatigue, and loss of consciousness at least once a week - and those who developed symptoms had significantly higher urinary mercury levels than those who did not, at p < 0.05. A multiple regression model was constructed. Significant predictors of urinary mercury levels included hours worked per day, days worked per week, duration of work (years), work position, use of PPE (mask, trousers, and gloves), and personal hygiene behavior (ate snacks or drank water at work, washed hands before lunch, and washed hands after work). Conclusion: Changing garbage workers' hygiene habits can reduce urinary mercury levels. Personal hygiene is important, and should be stressed in education programs. Employers should institute engineering controls to reduce urinary mercury levels among garbage workers.
