Detection of estrus is an essential factor as a method of successful breeding in the sow. As increasing the adaption of the information and communication technology (ICT) into swine industry, this study focuses on a possibility and quantification of standing time, vulva and body temperature as methods of estrus detection, comparing each time and temperature in estrus and non-estrus period, and analyzing each success rate of new and existing methods. Ultrasonic sensor array and digital infrared thermography were used to evaluate whether new methods such as standing time and number, and vulva and skin temperature can be replaced, or these methods can be quantifiable in estrus period. Ultrasonic sensor array was installed beside the stall and digital infrared thermography was placed in the rear of sow to collect the dates of sow in estrus and non-estrus period. This study showed total standing time, number and number over 10 minutes, and vulva temperature of the sow in estrus period were increased (p < 0.05) compared with those of sow in non-estrus period, respectively. Detection of estrus using standing time and vulva temperature tended (p = 0.06) to increase the success rate when artificial insemination (AI) was performed. In conclusion, standing time and vulva temperature increased when estrus happened. Success rate of AI of sow using these methods showed an increasing trend. Therefore, existing method using the naked eye can be replaced to new method such as vulvar temperature and standing time when detecting the estrus.

This study analyzed how North Korean defectors recognized and overcame conflict in the South Korean job culture during the course of entering and settling into South Korea, and the association between their old career and adaptation within their new careers. The study selected 13 employed participants who entered South Korea more than five years ago and experienced working. Interviews were conducted over the course of five years. The topics were analyzed after performing interviews 60 to 120 minutes long by recording and transcribing the recordings and using semi-structured questionnaires for the 13 people. The results reflected the job environment in North Korea, their career background, factors for a successful new life, their constant efforts for employment, the difficult adaption to South Korean life, pursuing job stability, accepting South Korean culture, and career compromises. The results of this study are as follows. First, they undergo difficulty in the course of selecting jobs due to the converted environment from passivity to autonomy. Second, they cannot use their previous job history and they complained about prejudice and the lack of job information. Third, major problems included their lack of adaptability, stress, and loss of economic power. The study suggests that these North Korean defectors undergo an integrated course of cultural learning. Fourth, they were hardly able to adapt. Fifth, they tried to overcome conflicts of job culture according to their personal characteristics.

The purpose of this study is to develop Family Life Education program for Marital education in Korea. In order to realize the about research purpose, this study is divided into three sections. First, nature conception and contents f Family Life Education, second, patterns and models for Family Life Education Program in USA and Korea, and Third, the future of Family Life Education. Family Life Education (FLE) is an education originated in reaction to changing social conditions, industrialization and urbanization, it deals with the perceived inadequacies of families to cope with these changes, thereby reduction social problems involved with, and improving family life. With and assumption that the studies about FLE have not been so active in Korea, the present thesis examines the FLE in Korea. The necessity of marital education in Korea Is based upon the theories of FLE in the United States of America. Also, it atempts to formulate a tentative plan for the promotion of a FLE program in Korea. The concept of FLE in Korea was manifested in the social educational law and life-span education. specified as 4th among ten presidential regulations. It is defined as " the Life-span developmental education to enhance the quality of human life, to solve family problems, to develop an individual's potentiality and to strengthen the family relations. of the FLE programs, the marital education is considered one of the furcial wubjects becaused it is the core of the family life. With this premise, FLE tries to wupport the healthy mrital relations. subsequently helping to explore the family potentiality and to strengthen family ties. The objects of the FLE program are unmarried, pre-marred , and married persons. For the married persons, the FLE program should be arranged in accordance with their rrital status divided by the family life cycle so that they may prevent possible family problems at each stage of the family life. Also, to prevent the problems occurred in the course of carrying out family functions, the FLE program should be provided with on the basis of a family unit, thereby improving the quality of the family functions. The FLE is to hep persons begin smoothly the adaption process for a successful marital relations. For the FLE to be practised more widely systematically, research on family education--that is basic study, research and production and evaluation or the FLE to be carried out by research institute wholly responsible for it-- should be done first.

This study was conducted to investigate that the mediating effect of interpersonal support in college students. Data were collected from the college located in G province, Korea from April, 1th to May 2th 2017. Data were analyzed by pearson correlation coefficients, and regression method of Baron & Kenny of SPSS 26.0 program, and Sobel test of Amos 16.0 program. The result were as follows; 1) The mean scores were college adaptation 5.30(.75), smartphone addiction 2.30(.48), interpersonal support 4.53(.75). 2) The college adaptation showed negative correlation with smartphone addiction(r=.328, p<.001) and positive correlation with interpersonal support(r=.490, p<.001) significantly. Interpersonal support showed significant negative correlation with smartphone addiction(r=-034, p=.04). 3) Interpersonal support had partial mediating effect(Z=2.16, p=.03) in the relationship between college adaptation and smartphone addiction. Baron & Kenny's three-step test showed that college adaptation(${\beta}=-.37$, p<.000) and interpersonal support (${\beta}=.30$, p=.15) were significant predictor variables for the smartphone addiction. Based on the results of this study, college program which is reinforce interpersonal support need to be applied and for the successful college adaptation and beneficial use of smartphone.

Background : The genus Cypripediums are typically adapted to the low temperature and cold climates of the high land in Korea. The species which were reported in Korean peninsula are C.japonicum, C.macranthos, C.calceolus and C.guttatum. We had already reported the successful germination of the C.macranthos and C.guttatum. The small spotted lady's slipper orchid(C.guttatum) is most endangered plants to extinction of which population was reported less than 100 in Korea. The objective of the present research is restoration of the C.guttatum in ex situ and adaptation in high land and nursery. Methods and Results : The 350 seedlings of C.guttatum were transplanted in soil at alpine area(altitude 750m) and the nursery of Korea National Arboretum(KNA) in YangPyeong city on May 2019 and 2020 in order to verify the possibility of ex situ restoration. The sprouted ratio of the seedlings were less than 10% in the alpine area and 83% in the nursery of KNA. The reasons of the diverse survival ratio are presumed as the low moisture content in the soil and heavy shade of the alpine area. The 15 cypripedium species and 29 hybrids were also effectively adapted in the KNA rare plant garden. Conclusion : These results demonstrated the difficulties of the restoration for small spotted lady's slipper orchid in the natural habitation. From the above results, we may conclude that the critical factors of the genus Cypripedium are intensive care for the fragile seedlings during the 1^st year acclimatization.
