Background: Police work is generally sedentary although there may be situations that require physical endurance and strength, such as foot chases and arresting suspects. Factors such as excessive body fat can impede an officer's physical ability to deal with such occurrences. Our objective was to examine associations between officers' body fat percentage (BF%) and performance on a standardized fitness protocol. Methods: Data were obtained from fitness screening among 1,826 male and 115 female officers in a large US police agency. The screening consisted of a 2.4-km run, push-ups, sit-ups, and sit-and-reach test. Sex-specific body fat percentages were estimated from skinfold thickness measured using calipers. Linear regression models were used to examine unadjusted and adjusted mean scores of fitness tests across BF% tertiles. Results: The prevalence of overall fitness was 4.3 times greater in male officers and 3.6 times greater in female officers having the lowest BF% tertile compared with the highest tertile (30.3% vs 7.1% and 46.0% vs 12.8%, respectively). BF% was linearly and positively associated with the time of 2.4-km run (p < 0.001), and linearly and inversely associated with the number of push-ups (p < 0.001), sit-ups (p < 0.001), and the distance of sit-and-reach (p < 0.001) in men. Similar associations were observed in women with the exception of sit-and-reach (p = 0.122). Associations were independent of age, race/ethnicity, rank, and duty station. Conclusion: Overall, BF% was inversely associated with fitness levels in male and female officers. Future longitudinal studies should be initiated to explore the potentially causal relationship between BF% and fitness in law enforcement officers.

In a situation where there is excessive competition among logistics centers due to the low price of logistics centers for attracting freight volume, the conditions provided by the logistics centers are similar. Therefore, in order to determine the logistics center, we want to find out what kind of differentiated service the shippers desire, as well as what level of service they want in addition to al ow price. There are currently no studies about the service quality of logistics centers. The components of the service quality of the logistics center were extracted by applying them to the logistics center based on the existing service quality theory. Factor analysis revealed five dimensions of service quality: tangibility, reliability, empathy, assurance, and know-how. It was found that service quality had a statistically significant influence on customer satisfaction, from the investigation of the causal effect relationship. In addition, 'Know-How' among these factors has more influence on customer satisfaction, so it is important to accumulate differentiated 'Know-How' only in logistics centers.

The purpose of this study was to explore the causal relationships between turnover intention and its influencing factors among married female nurses. The participants included 148 married nurses at 5 general hospitals in J city. Data were collected by using self-reported questionnaires and were analyzed by using SPSS and AMOS software. The overall fitness of the modified path model to the data was good ($x^2/df=0.002$, GFI = 1.00, AGFI = 1.00, RMSEA = 0.00, NFI = 1.00, CFI = 1.00, TLI = 1.09). Job stress, social support, work-family conflict, and burnout explained 32.0% of the variance in turnover intention of the participants. In particular, work-family conflict had a complete mediating effect between job stress and burnout. In addition, work-family conflict had partial mediating effects between social support and burnout as well as between social support and turnover intention. Social support had direct and indirect effects on work-family conflict, burnout, and turnover intention. In conclusion, strategies for decreasing married nurses' burnout and turnover intention should focus on reducing work-family conflict and increasing social support.

This study analyzes the structural causal relationship among adult learners' characteristics, participatory motivation, methods of learning process by instructor, institutes satisfaction, and learning outcome. In addition, the study reviews the mechanism by which three different variables work as intermediates in the relationship between adult learners' characteristics and learning outcomes. The study subjects were 444 adult learners who participated in lifelong education, and the research hypothesis was verified through Structure Equation Modeling analysis. The results are as follows. First, the characteristics of adult learners affect learning outcomes, as well as the methods of learning process by instructor affects, participatory motivation and institutes satisfaction, and have a significantly positive(+) effect. Secondly, the methods of learning process by instructor affect institutes satisfaction, and the effect is significant. However, it does not influence participatory motivation. Moreover, it has a negative influence on learning outcomes. Additionally, participatory motivation has a significant effect on both learning outcomes and institutes satisfaction. Thirdly, when examining the ultimate intermediate between the characteristics of adult learners and their learning outcomes, institutes satisfaction was the optimal channel. These study results suggest not only the role of lifelong education institute, but also ways to improve academic outcomes of adult learners within the lifelong education field.

The process of fertilization and changes in anatomical structure of sclerotia during the apothecial formation in Sclerotinia trifoliorum, the causal fungus of sclerotial rot of forage legumes, were investigated. The time of fertilization could be estimated with fair accuracy by the sequencial spermatization of the sclerotia which kept at 15C in saturated moisture. In the case of one strain used in this experiment, fertilization between the sclerotia and spermatia were estimated to take place at around 18days after the sclerotia were placed under the conditions for apothecial induction (15C, saturated moisture). The fertilizable state was maintained for about 45 days and the spermatization thereafter did not induce the apothecial formation. When the sclerotia reached fertilizable state, a number of interwoven hyphal nests were developed within the medulla of sclerotia, regardless of the sexuality of the cultures. Comparing the process of multiplication and growth of the hyphal nests in homothallic and heterothallic culture, they were identified as ascogonium. These ascogonia were persisted for about 45 days. This observation was well coincided with the duration of fertilizable state elucidated by the sequencial spermatization experiment.

The purpose of this study is to explore various factors during the career development period affecting the formation of the perspective on work of young workers after they graduated from high school, and to analyze the influence of each factor. The panel data of the Korean Education Longitudinal Study 2005 was used for the study. Specifically, the data on the 303 employees in the 7th year(2011) of their employment was used. First, perspective of young workers on work was affected by social self (self-awareness-related variables), educational background of their father(family background-related variables), and intrinsic and extrinsic learning motivation(learning motivation-related variables) formed during the career development period. However, extrinsic learning motivation had a passive and negative effect on motivation and giving value to work. Second, the variables related to self-awareness in the career development period and the variables related to the family background were found to have a causal relationship with the formation of young workers' perspective on work. This study is significant in that the learning motives formed during the career development period are found to be very meaningful and important variables for the formation of young workers' perspective on work.
