The importance of forecasting agricultural production is receiving attention while climate change is accelerating. This study suggested three types of crop yield forecasting model for major vegetable crops by using downscaled meteorological information of main production area on farmland level, which identified as limitation from previous studies. First, this study conducted correlation analysis with seven types of farm level downscaled meteorological informations and reported crop yield of main production area. After, we selected three types of meteorological factors which showed the highest relation with each crop species and regions. Parameters were deducted from meterological factor with high correlation but crop species number was neglected. After, crop yield of each crops was estimated by using the three suggested types of models. Chinese cabbage showed high accuracy in overall, while the accuracy of daikon and onion was quiet revised by neglecting the outlier. Chili and garlic showed differences by region, but Kyungbuk chili and Chungnam, Kyungsang garlic appeared significant accuracy. We also selected key meteorological factor of each crops which has the highest relation with crop yield. If the factor had significant relation with the quantity, it explains better about the variations of key meteorological factor. This study will contribute to establishing the methodology of future studies by estimating the crop yield of different species by using farmland meterological information and relatively simplify multiple linear regression models.

Recently, the expansion or establishment of facilities for the logistics system is increasing. Conveyor facilities play a major role in sorting and transporting logistics. Induction motors are widely used for the operation of these conveyor systems. In the logistics system, a large number of induction motors are used. These motors have a considerable distance from the power source side and have a low power factor. The installation position for the power factor compensation of the induction motor is very important. Since the voltage drop depends on the length of the line, it is an important parameter in capacitor capacity determination for power factor compensation. The capacity of the capacitors installed to compensate the power factor of the inductive load should be designed to the extent that self-excitation does not occur. In this study, we analyze the method of compensating the proper power factor considering the voltage drop and the installation position of the induction motor in the logistics system.

This study is intended to determine the effects of volunteering participation motivation on major satisfaction and continuance willingness in ophthalmic optics students. To achieve this, a survey was empirically carried out to ophthalmic optics students. The research findings showed that self-development among participation motivation factors had a significant effect on major satisfaction and continuance willingness, leisure on continuance willingness, and major satisfaction on continuance willingness in the relationship between the effects of volunteering participation motivation on continuance willingness and major satisfaction in ophthalmic optics students, respectively, adopting 3 hypotheses. On the other hand, leisure had no significant effect on major satisfaction, interpersonal exchange on major satisfaction, and interpersonal exchange on continuance willingness, respectively, rejecting 3 hypotheses. Which suggest that the high self-development willingness of college students as a factor of college volunteering participation motivation causes them to have pride and specialization in their major. Consequently, pride and specialization in major cannot only increase an understanding of personality and major, but maintain a positive attitude, leading to a long-continuous willingness, not a simple one-time service.

The purpose of this study is to explore ways to improve major satisfaction that can be applied by universities through the analysis of factors influencing major satisfaction of engineering college students. To this end, Korea-National Survey of Student Engagement(K-NSSE) data involving 814 students from T University were used, and logistic regression analysis and t-test were applied. The main results obtained through this are as follows. First, engineering college students' major satisfaction factors include major-career relevance, college immersion, and positive academic sentiment. Second, depending on the grade, it was confirmed that the factor of major-career relevance in the lower grades, and the factors of meaningful learning experience and college immersion in addition to major-career relevance in the upper grades had a significant influence. Third, the higher the meaningful learning experience, positive academic sentiment, and college immersion, including the major-career relevance, the higher the major satisfaction was found in the middle-class group with a score of BO or higher. This study is meaningful in that it revealed differences in influence by individual characteristics as well as major satisfaction influencing factors that can be practiced in universities such as learning experiences.

The purpose of this study was to compare clothing attitudes and the criteria for clothing selection between Korean and Korean-Chinese college female students in the Yanbian region of China. The subjects were selected as follows: 404 Korean female college students in the Choongchung area and 242 Korean-Chinese female college students in the Yanbian region of China. Questionnaires were used to collect the data and the data was analyzed by frequency, factor analysis, and t-test. The major results of this study were as follows: The clothing attitudes of the total respondents were classified into 5 factors: the fashion involving factor, the modesty involving factor, the economy conscious factor, the brand-name oriented factor, and the practical user factor. The modesty involving factor, the economy conscious factor, the brand-name oriented factor, and the practical user factor were significantly different between Korean and Korean-Chinese college female students. Korean consumers thought highly of the economy conscious factor and the practical user factor compared with Korean-Chinese college female students. However, Korean-Chinese college female students thought highly of the brand-name oriented factor and the modesty factor compared with Korean consumers.

In this paper, fatigue tests were carried out at stress test levels of 461 MPa, 441 MPa, and 431 MPa by using smooth specimen of$2_{1/4}$ Cr-1 Mo steel with the stress ratio(R) of 0.05. The initiation, growth and coalescense process of the major cracks and sub-cracks among the fatigue cracks on the smooth specimen are investigated and measured under each stress level at a constant cycle ratio by the replica technique with optical microscope. Some of the important results are as follows: In spite of the difference of stress levels, the major crack data gather into a small band in the curve of surface crack length and crack depth against cycle ratio N/Nf. The sub-crack data, however, deviate from the band of the major crack. The growth rates, da/dN, of major and sub-crack plotted against the stress intensity factor range, ${\Delta}K$, have the tendency to be compressed on a relatively small band. But it is more effective to predict fatigue life through major cracks. The propagation behavior of surface microcracks on the smooth specimens coincides with that of the specimen having an artificial small surface defect or through crack.
