The purpose of this study was to identify the correlation and level of Body Mass Index, Body Shape Dissatisfaction, Eating Behavior in college students. Methods: A total of 383 students were asked. The survey was analyzed by SPSS Win 21.0 program. 293 were female students and most of the students were normal in BMI(58.2%), and underweight students were the next(14.9%). There were positive correlation between body shape non satisfication and eating behavior and BMI(r=.587, p=.000; r=.174, p=.001), and negative correlation between body shape non satisfication and age and sleeping time. According to BMI the body shape non satisfication was different in normal and 1 stage obesity students. and 2 stage obesity and under weight students (F=2.993, p=.019;F=2.993, p=.109). As a result of this study, students with body mass index overweight have low body satisfaction, so it is necessary to educate the right dietary exercise therapy for weight management. And even underweight groups should be mediated so that they undergo normal diet behaviors, rather than restrained dietary behaviors, to maintain health.

The purpose of this study was to investigate the impact of issue leadership by sales managers on sales team performance, while examining the mediating role of team adaptive sales behavior and the moderating effect of team-member exchange (TMX). Data was collected from 125 sales teams, and both independent and dependent variables were measured with a time difference of two months using responses from sales managers and team members. The empirical analysis revealed several important findings. Firstly, the study found that issue leadership had a significant positive effect on sales team performance. Secondly, team adaptive sales behavior was found to partially mediate the relationship between issue leadership and sales team performance. Lastly, the study revealed that TMX moderated the relationship between issue leadership and sales team performance. These findings have significant academic and practical implications. Firstly, the study demonstrates the effectiveness of issue leadership as a sales leadership style in the B2C industry. Secondly, it highlights the importance of team adaptive sales behavior as a mechanism that mediates the relationship between issue leadership and sales team performance. Lastly, it underscores the significance of TMX as a situational factor that moderates the relationship between issue leadership and sales team performance. In practice, the results suggest that organizations should focus on developing issue leaders, fostering creative sales behavior at the team level, and activating social exchange within sales teams to enhance sales team performance.

This study was conducted to obtain meaningful information about job management of child care center teachers, who take charge of child care policy at the front line, social meaning of which is being greatly highlighted these days. Especially, the research was designed with causal relationships in mind, in which certain job-related thoughts or consciousness forms attitudes, thus leading to behavior. In this light, the present study selected the following variables for analysis: job attitudes including job calling, job engagement, and job burnout; and job behavior such as creative behavior, active behavior, and ethical behavior. Data collected from 209 child care center teachers' response to structured questionnaires was analyzed, using t-test, one-way analysis of variance (one-way ANOVA), and hierarchical regression analysis. The results indicate that job burnout increased at a statistically significant level as extra workhours increased, and that only job engagement, among job attitude variables, and creative behavior and active behaviors, among job behavior variables, had significant effects. Moreover, job engagement was the only variable that was found to work as a mediator in relationships between job calling and active behavior.

This study examined the effects of sex in different group sizes of Hanwoo calves. The growth performance including the mean daily gain, feed conversion rate, behavioral characteristics, and blood parameters in Hanwoo calves were investigated. A total of 54 heads of Hanwoo calves were housed separately at 4 heads per group, 3 heads per group, and 2 heads per group per pen. In the heifer calves, except for those 10 months of age, the growth performance was improved by increasing the group size, which was similar to steer calves (p<0.05). The heifer calves housed in 3 heads group spent more time lying down (p<0.05). The steer calves spent more time standing in the 3 heads group, lying down (2 heads group), and walking (4 heads group). The heifer calves housed in 2 heads group had a lower frequency of drinking, self-grooming, pairwise grooming, and fighting (p<0.05). On the other hand, the steer calves in the 4 heads group had a higher frequency of drinking, rubbing, and fighting (p<0.05). The white blood cell and cortisol were highest in the heifer calves in the 2 heads group (p<0.05).

Early introducing the ducks into the paddy field involves a variety of environmental changes such as new surroundings and contact with water, so that some free-ranged ducks show behavioral and physiological changes indicative of stress or die from not adapted for new circumstances. Moreover, the free-ranged ducks was tread on the rice plant, and required a great deal of labor and time for captured the ducks after finishing the introducing. The aim of the present study was to examine the effect of accustoming and imprinting of duckling on behavior patterns, body weight gain and yield of the rice plant in paddy fields. Three paddy plots were used as control (no imprinting and no contact with people), taming (imprinting and regular handling) and roughness (handling roughly and strike terror to ducks) plots. Right after introducing the ducks into the paddy field, eating and moving behaviour of taming plot ducks tended to be longer time spend than that of other treatments. However, eating and moving time tended to be longer in the control than that of other two treatments on the 2 weeks after. Flighting distance was not showed in the free-ranging period taming plot, but the control plot was significantly (P<0.05) longer than the roughness plot. The captured time of free-ranged ducks tended to be shorter in the order of taming, control and roughness plots. Body weight gains was not significant. The number of rice plants damaged by free-ranging ducks in the taming plot were significantly (P<0.05) less than that in the control plot, but the yield and yield components of the rice plant were not differ among 3 treatments. These results indicated that the imprinting or regular handling and related treatments of duckling was reducing badly damage of rice plants, captured time and labor of free-ranged ducks in paddy field, although the working behavior of ducks and yield ability of the rice plants were not affected.

컴퓨터교과는 학생들의 일반적인 학업성취 개인차 요인과 더불어 필수 교과가 아니기 때문에 학교 혹은 교사마다 교육하는 내용이 상이하여 학생들이 상급학교로 진학하였을 때 학생들 간의 수준 차가 심화된다. 이러한 다양한 수준차가 있는 학생들을 교사 1인이 한정된 시간 안에 모든 학생들의 수준에 맞추어 지도하는 것은 대단히 어렵다. 또 넓은 컴퓨터실에서는 학생들의 주위가 분산될 우려가 많으므로 학생들의 행동을 수시로 관리할 필요가 있다. 이러한 컴퓨터교과 실습수업 시에는 보다 효과적인 지도방법이 요구된다. 이에 본 연구에서는 컴퓨터교과 실습지도 방법의 장단점을 분석하고, 컴퓨터교과 실습수업 시 널리 사용되는 시범 실습법의 단점을 보완할 수 있는 도우미학생 활용 시범 실습법을 제안하고, 중학교 컴퓨터 정규교과 시간에 적용하여 그 효과를 검증하였다. 도우미학생 활용 시범 실습법이란 교사는 실습내용을 설명하고, 모든 학생들은 교사의 설명과 동시에 실습을 하며, 도우미학생의 실습내용이 빔 프로젝트를 통해 다른 학생들에게 보여짐으로써 교사의 시범을 대신하는 방법을 말한다. 컴퓨터교과는 설명만으로도 실습 가능한 내용이 많아 이러한 지도방법이 가능하다 이 방법은 실습내용을 최소한의 작은 단계로 구분하고, 각 단계별로 교사의 설명과 개별지도, 모든 학생의 실습과 관찰이 동시에 이루어진다. 이 방법은 교사의 행동이 자유로워 설명과 동시에 개별지도가 가능해 개별지도의 확대를 가져올 수 있으며, 학생들에게 보다 많은 즉각적인 피드백을 줄 수 있으며, 학생들의 행동을 수시로 관리할 수 있다는 장점이 있다. 또한 본 연구에서는 검증도구로 'html 태그' 단원 5차시 분량의 과제수행능력평가도구를 개발하여 사용하였다. 검증결과 학업성취 중하수준의 도우미학생 활용 시범 실습으로 수업한 집단은 통제반과 유의미한 차이가 없었으나, 학업성취 중상수준의 도우미학생 활용 시범실습으로 수업한 집단은 통제반에 비해 과제수행능력에 있어서 유의미한 차이를 보였다 이로써 제안한 지도방법의 효과성을 입증하였다.

Analysis of risky behavior factors for workers in the manufacturing industry enables effective human error prevention and systemization of an efficient safety management system. This study examines the relationship between the effects of workers' work psychology, work environment, and work deviation factors on risky behavior intentions and the effects of such risky behavior intentions on risky behaviors. Among the small and medium-sized manufacturing industries, the analysis was focused on a survey of 80 workers in the manufacturing and processing industry. Looking at the results, it was found that work psychology and work deviation had an effect on the intention of risky behavior, but the work environment factors corresponding to job satisfaction and workload did not affect the intention of risky behavior. The relationship with colleagues, the degree of satisfaction or dissatisfaction with the job, the degree of importance of the job that the worker feels, and the tightness of time to digest a large amount of work do not affect intentionally inducing dangerous work, but they do affect risky behavior. In the absence of intention, the work environment factor was found to accompany dangerous behavior.
