본 연구는 수입건초의 품질평가를 통해 사료가치를 평가하고 초종 및 등급별 현황을 파악하고자 수행되었다. 수입건초의 품질 평가를 위하여 2016년부터 2018년까지 전국 건초 수입상, TMR 회사와 축산 농가에서 목건초 9종 133점을 수집하였다. 수입건초의 품질등급이 3~4등급 수준으로 대부분의 수입건초가 사료성분이 낮은 것으로 판단된다. 알팔파의 품질등급별 사료성분은 ADF, Ash, TDN 및 DDM에서 유의적인 차이가 나타났다(p<0.05). 알팔파에 표기된 품질등급이 사료성분을 통해서 산출된 실제 품질 등급과 유사하지 않았다. 화본과목초의 품질등급별 사료성분은 DM 및 CP를 제외한 모든 항목에서 유의적인 차이가 나타났다(p<0.05). 국내에 유통되는 화본과목초 중에서 저품질인 품질등급 미표기가 49%를 차지하고 있으므로 사료성분에 따른 품질기준 제시가 시급하다. 이상으로 수입건초의 사료성분을 검토하였을 때 표시된 품질등급보다 낮은 결과를 나타내었다. 이는 수입건초에 표시된 품질등급만으로 판매가격을 책정하는 것은 축산 농가 및 사료제조사 등에 경제적 손실을 야기한다고 볼 수 있다. 수입건초의 품질등급을 재 검토하는 제도적 장치가 마련되어야 한다.

This study aimed to examine the effects of ego-resilience and social support on parenting stress perceived by mothers of school-aged children. The effects of demographic variables(including school grades of children) on the mothers' parenting stress were also investigated. The main results were as follows. First, ego-resilience of mothers was found to have the greatest predictive power on mothers' parenting stress. The more ego-resilient the mothers were, the less parenting stress was perceived. Second, social support also played an important role in alleviating maternal parenting stress. Emotional support of spouses was particularly effective in reducing mothers' parenting stress. Third, the only demographic variable that influenced mothers' parenting stress was their children's academic achievements. Finally, mothers perceived high parenting stress in relation to their children's school grades, while they perceived relatively less parenting stress concerning their children's temperament or the relationship with their children. The implications of these results were discussed.

Feeding preference of cigarette beetle, Lasioderma sewicorne F., on cured tobacco leaves was investigated to obtain basic information on ecological management of the insect pest in tobacco storage warehouses. About 3, 000-4, 000 adults of the insect were released in a warehouse in which groud tobacco leaves were placed on the bottom and at 3m above the floor level, and numbers of insects attracted were examined. There was no significant difference on feeding preference between the two tobacco varieties, flue-cured(NC82) and air-cured(Br3l) tobacco leaves. However, significant differences were noted in feeding preference between thick and thin leaves and among different quality grades within a tobacco variety. Feeding preferences of cigarette beetle between flue- and air- cured tobacco varieties showed significant differences on the lower position, though there were no differences on the 3m upper position. On the 3m upper position, feeding preferences were different between thick and thin leaves of tobacco varieties, and variety X thickness and variety X thickness equality grades showed statistically significant differences. Significantly higher feeding preference by cigarette beetle adults was observed for the food placed on the 3m upper than on the lower position. There were negative correlations between quality grades of cured tobacco leaves and feeding preference on the lower position, and the regression equation was Y(feeding preference)=4.050-0.683 X (degree).

Elementary science curriculum is designed to be closely-related magnetism with electricity in a physics domain and this paper explored whether elementary school students have recognized of relationships between them and whether there are any trends in the degree of recognition by grades. The elementary students of 3rd to 6th grade (total 154 persons) in a school in a local city participated in the experiment. Two forms of questionnaire were administrated to each grades. In the first questionnaire about magnetism, students were asked to rank the physics terms as the degree of proximity into magnetism and to write briefly the reason. In the second questionnaire about electricity, students were asked to do the same routine. The closer to the central term in the diagram, the lower score were given and the terms were classified as closely related to magnetism, electricity and the rest. Calculated the response frequency and averaged by the ranked terms, it was examined that the scores of proximity in how students closely rated conception to magnetism and electricity. The result said that the upper grades students showed the degree of proximity with magnetism and electricity as closely. Therefore, the sequence of comprehension of magnetism and electricity concept, which was found in the elementary school curriculum, seems to be found in the elementary students＇ recognitions by grades.

Objective : To investigate how general characteristics and life habits of patients affect severity of acne which was determined by Korean Acne Grading system(KAGS). To adress correlation between the severity of acne and subjective stresses from which patients suffer. Methods : 86 patients answered to questionaire sheet on their general characteristics and life habits and rated their level of stresses as a number in the range between 0 and 10. Then an oriental medical doctor evaluated subject's acne grades, based of KAGS, through observations on papules, nodules, and scars before (medical) treatments. All data (collected) were analyzed using SPSS 22 (software for windows). To clearly demonstrate association of subjects general characteristics, life habits with KAGS grades, Chi-square tests were performed. The correlation between the KAGS grades and the level of stresses was determined using one-way ANOVA followed by Scheffe's post-hoc analysis. Results & Conclusion : Majority of subjects were women, students between 15 and 25 years old, and patients with normal range of Body Mass Index(BMI). Dysmenorrhea presence and premenstrual exacerbation of acne had statistically significant relationship, suggesting their potential influences on KAGS grades as major factors.

The purpose of this study was to investigate the effect that completing long-term on-site training with varying grades of success had on the job satisfaction of former university students after obtaining employment. Although the grades themselves achieved during long-term on-site training did not directly affect job satisfaction, positive effects on job satisfaction were shown due to the mediating effects of job match and organizational commitment. The results of this study are as follows: First, it was found that employees who participated in long-term on-site training showed different results in belonging and attachment to their organizations according to their achievement. The higher the grades during long-term on-site training, the higher the degree of reported job match and organizational commitment, suggesting a positive correlation with job satisfaction. Therefore, long-term on-site training should not be operated as simply a program for temporary experiential learning, but instead should be optimized by companies and schools to motivate their students to achieve high grades for the purpose of their future job satisfaction.

With the emphasis on core competencies, the University of Seoul has exerted efforts to reflect the importance of core competencies in university curricula. The main assessment tool used in Korea is the Korea Collegiate Essential Skills Assessment (K-CESA), developed by the Korea Research Institute for Vocational Education and Training (KRIVET). This study examined whether core competencies measured using K-CESA are valid as a tool for assessing educational achievements among college students, and analyzed the correlation between K-CESA scores and course grades. The analysis was performed on approximately 204 engineering students at the University of Seoul. According to the correlation analysis between core competencies and courses, MSC courses were shown to be related to the resource and through information use competency and higher order thinking competency. Through the Analysis of Variance, students in the accreditation programs and students living in urban area showed higher competency scores. In the multiple regression, it was shown that Accreditation and MSC courses grades were the important variables to predict the competency of the students. Based on these findings, we confirmed that the K-CESA tool has a certain level of correlation with academic performance and that it functions as one of several ways to evaluate the program outcomes of engineering education accreditation.
