This study was carried out to investigate the reproductive performance of average (less than 10,000 liters milk in 305 days) and high yielding (more than 10,000 liters milk in 305 days) Holstein cattle at commercial dairy herds (n=22). Data on milk progesterone (10 to 60 days postpartum), days to post-partum estrous, days to post-partum conception, service per conception and calving interval were recorded for two consecutive years. Post-partum milk progesterone concentration and days to reach peak milk progesterone concentration were similar in high and average yielding cows. High yielding cows took more days to show signs of first postpartum estrous than average yielding cows. Post-partum conception was 20 days earlier in average yielding cows than high yielding cows. Artificial insemination per conception was similar between average and high yielding cows. Calving interval was 26.9 days longer in high yielding cows compared to average yielding cows. In conclusion, better reproductive and feeding management may help improve the reproductive performance of high yielding dairy cattle in commercial dairy farms.

This study is to investigate the factors influencing the problem solving ability of dental hygiene and students' communication ability and critical thinking and autonomous educational climate. The subjects were 249 dental hygienists who attended two university from May 20 to June 1, 2018. Statistical analysis was performed with mean, t-test and one-way ANOVA. The overall mean of critical thinking tendency was 3.47 points, the total mean of communication life was 3.48 points. The overall mean of autonomous educational climate was 3.14 points and the total mean of problem solving ability was 3.40 points. The higher the critical thinking disposition score, the higher the problem solving ability. The higher the satisfaction of the major, the higher the problem solving ability. Therefore, if the program to improve communication ability, critical thinking tendency, and autonomous educational climate of college students majoring in dental hygiene is expected to improve the problem solving ability.

산소는 인간의 신체 및 정신 활동에 필수적인 물질이며, 특히 뇌 기능에 중요한 역할을 수행한다. 본 연구에서는 일반 공기 중의 산소 농도(21%) 환경에 비해 외부에서 고 농도(30%)의 산소 공급이 인지 능력 중 특히 공간 지각 능력에 어떠한 변화를 유발하는지 관찰하고자 한다. 8명의 남자 대학생(평균 23.5세)을 본 연구의 실험 참여자로 선정하였다. 21%와 30% 산소 농도를 각각 8L/min의 양으로 일정하게 공급할 수 있는 장치를 개발하여, 마스크를 통하여 실험 참여자에게 전달하였다. 공간 지각 능력 측정으로 위해 각각 20문항을 포함하는 두 개의 문제지를 제작하였고, 과제 수행 결과로부터 정답률과 평균 반응 시간을 산출하였다. 평균 정답률은 21%와 30% 산소 농도에서 각각 50.63 $\pm$ 8.63과 62.50 $\pm$ 9.64 이었고, 두 농도간의 통계적 유의차가 발생하였다. 평균 반응 시간의 21%와 30% 산소 농도에서 각각 6.60 $\pm$ 0.77〔sec〕이었고, 두 농도간의 통계적 유의차가 발생하지 않았다. 본 연구 결과로부터 외부에서의 고농도의 산소 공급이 공간 지각 능력 증가에 긍정적인 영향을 미친다는 결론을 도출할 수 있다.

This study is for effectiveness of golf skills to average score using path analysis in Professional golf association. The variables in this study were that seven independent variable were driving accuracy, green in regulation, driving distance, sand save ratio, scrambling, putting average, and two endogenous variables were birdie average, bogey average, and dependent variable was the scoring average. To analyze these variables, path analysis was used through AMOS 18.0 program and Alpha level sets at.05. As the result, the final model had significant goodness-of-fit (GFI=.989, RMSEA=.044, TLI=.991, CFI=.998) and showed that green in regulation, driving distance, sand save ratio, scrambling, and putting average significantly affected average score directly. Especially, the scrambling was the highest affectation to average score and the sand save ratio was the lowest affectation to the average score.

In this study, we investigate the effect of twenties female caffeine addiction on cardiorespiratory capacity. For this study, we divided 35 female students at H university into caffeine addict group(n=17) and none caffeine addict group(n=18). Measure maximal oxygen uptake, maximal energy consumption and METs using Cycle Ergometer to assess cardiac capacity. Measure peak inspiratory pressure, peak inspiratory flow rate, peak inspiratory capacity, average inspiratory pressure, average inspiratory flow rate, average inspiratory capacity using Power Breathe K5 to assess respiratory capacity. As a result, cardiac capacity showed a statistically significant decrease in maximal oxgen uptake and METs compared caffeine addict group to none caffeine addict group(p<.001). respiratory capacity showed a statistically significant decrease in peak inspiratory pressure(p<.05), peak inspiratory flow rate(p<.01), average inspiratory pressure(p<.01), average inspiratory flow rate(p<.01), compared caffeine addict group to none caffeine addict group. Combining the results of the study, we could see that caffeine addiction reduces the cardiorespiratory capacity in twenties female. Therefore, it could be used as a basis date to prevent caffeine addiction for twenties female.

브로일러 종계의 평균능력은 혈통의 유전적 잠재력과 그 품종이나 계통의 관리 여하에 따라 여러 형태로 표현된다. 실제로 종계에서 나타나는 변이는 일반적으로 유전적인 차이보다 관리에 의해 더 많이 좌우된다. 여기서는 종계의 생산성 향상과 능력 개량을 좀 더 구체화시키기 위해 1976년부터 1981년까지 6년간의 자료를 구했다.

The purpose of this research are as follows. The first is to investigate the mediating effect of interpersonal skill on the relationship between the ability to use Internet and social activity among the 50's and 60's. The second is to compare 60's latent mean of core variables with 50's ones in terms of information gap. The data was Seoul welfare panel data made by Seoul welfare foundation in 2008 and the total subject was 941(50's=644, 60's=297). When it comes to the research methods, structured equation analysis for verifying the mediating effect and latent mean analysis for comparing the two groups were practiced. The results of this research are as follows. First of all, interpersonal skill did function as partial mediator. Second, according to the latent mean analysis, the group of 50's showed a more higher level of the ability to use Internet. On the other hand, the group of 60's revealed a more active social participation. In conclusion, Information educational programs should focus on Internet communication skill for enhancing social activities of the elderly and consider the differentiations among the elder generations.

The purpose of this study was to examine the relationship between perceived stress, college life adjustment, and interpersonal relationship ability in nursing college students and investigate whether or not interpersonal relationship ability mediate the relationship between perceived stress and college life adjustment. Data were collected from 281 nursing students in B city and analyzed by t-test, ANOVA, Pearson correlation coefficient, multiple regression, and sobel test using SPSS/WIN 23.0. The degree of college life adjustment in nursing students was 3.38±0.58. There was negative correlation between college life adjustment and perceived stress(r=-.478, p<.001), positive correlation between college life adaptation and interpersonal relationship ability(r=.617, p<.001). The interpersonal relationship ability had partial mediating(β=.629, p<.001) effect between perceived stress and college life adjustment among nursing students. Therefore, in order to promote college life adjustment of nursing students, and decrease perceived stress, it is necessary to development education and program that to improve interpersonal relationship ability.

The purpose of this study was to identify the effect on the evaluation of a female teachers' role-performance based on appearance according to the clothing attitude of students and their parents. Based on the results of this study a female teachers' role-performance evaluation can be broken down into four ability areas: leaning guidance, living guidance, human relations, and learning management. Likewise the clothing attitudes of students and their parents can be divided into three groups, the clothing oriented group, the trend-individuality group, and the chastity oriented group. The trend-individuality group of students felt that female teachers' appearances have a significant effect on learning guidance and human relations ability while parents thought that there was little relationship or that it has a moderate effect on the role of learning guidance. Because the concerns of students and parents about female teachers' clothing has an effect on female teachers' role performance evaluation, when directing a student group with a high concern for clothing, female teachers need to be sensitive about their appearances and it's affect on learning guidance, human relations, and class management. Based on these results, students and parents felt that female teachers' appearances have an effect on their role performance according to their clothing attitudes.
