This study identified the relationship between academic stress and hopelessness among female high school students. The self-administered questionnaires were given to 334 female high school students located in D-city during the period from August 20, 2018 to September 20, 2018. As a result, the distribution of the level of hopelessness among those surveyed was 61.6% for the normal range group, 23.1% for the mild range group, 12.9% for the moderate range group, and 2.4% for the severe range group. The level of hopelessness, according to the academic stress of the study subjects, was significantly higher in the higher academic stress group than that in the lower academic stress group (p=0.000). Hopelessness also showed significant positive correlation with academic stress (r=0.371, p<0.01). The results of the logistic regression analysis showed that the risk ratio of hopelessness was significantly increased 9.27 times in the higher academic stress group when compared to that in the lower academic stress group. According to the multiple regression analysis, the significant variables affecting hopelessness were satisfaction with school life, conversation with parents, eating regularly, stress due to tests, stress due to studies and stress about career paths. Given the above results, the hopelessness of female high school students is significantly related to academic stress. Therefore, it is necessary to develop and implement programs that can properly control academic stress factors.

Orthodontists want why the patients want orthodontic treatment. Demand and need for orthodontics is very important factors of cooperation and management. Chief complaint would be different according to the race and culture. Our results show that in the control group, Korean female adolescents[chief complaint is cowding$(30.6\%)$, spacing$(26.5\%)$, upper anterior protrusion$(18.4\%)$, anterior cross bite$(8.2\%)$ in order. Korean female adolescents considered anterior cross bite is more nonacceptable than spaeing and anterior protrusion. The purpose of orthodontics seemed to enhance esthetic, dental health, and to improve oral function.

This qualitative study focused on the motives and patterns of child care leave by analyzing its facilitating and constraining factors. Fourteen participants were interviewed in-depth using non-structured interview questions. Motives for child care leave include mothers' active choice, mothers' inevitable secondary choice, and mothers' instrumental choice. The patterns of child care leave in terms of total period, time, and distribution vary according to individual circumstances and occupational culture surrounding child care leave for female workers. Female workers will occasionally use this child care leave as a rare opportunity to take a rest during their labor lifecycle and to achieve work-family balance.

This study was designed to evaluate the possibility of increase through dairy female offspring's ratio by transfer of pre-selected transferrable blastocyst that was produced by pre-selected X-bearing semen with OPU derived oocytes. Elite dairy female cow is demanded strongly compared with male, the so called, farmer wants to produce only an elite female dairy offspring as a candidate female dairy cow for producing milk. In our study, we selected 2 elite dairy bull semen from National Agricultural Cooperative Federation to pre-select X-bearing semen and 5 elite dairy female cows as donor for collecting of OPU derived oocytes. OPU derived embryo production system was carried out an aspiration of immature oocytes from 5 donor cows 2 times per week, total 200 times for 2 to 7 months by an ultrasonographic guided follicular aspiration system and then produced in vitro-produced blastocysts by in vitro maturation, fertilization and culture. Dairy donor semen selected H-319, 320 bull in National Agricultural Cooperative federation was sorted X-bearing semen by flow-cytometer and frozen for using IVF with OPU derived oocytes. Donor cows were selected 5 elite dairy cows from Gyeongju Dairy Cow Community and then disease tests such as 4 kinds of disease before selecting was checked. Oocyte proportion of grade 1 to 3 from total collected oocytes was significantly lower in donor A and B than those in donor C, D and E (82.16 and 70.03% vs. 90.0, 91.78 and 93.57%), respectively (p<0.05). However, number of oocytes per session in donor A, C and E was significantly higher than those in donor B and D ($7.77{\pm}3.26$, $5.85{\pm}2.10$ and $7.03{\pm}2.14$ vs. $4.68{\pm}2.61$ and $5.21{\pm}1.97$ oocytes), but donor A was significantly higher than donor C (p<0.05). Development to blastocyst in donor B, C and E was significantly higher than those in donor A and D (31.0, 25.0 and 25.0% vs. 14.3 and 4.5%), but donor A was not different in donor C and E (p<0.05). Nine out of 10 blastocysts (90.0%) derived from OPU blastocysts were confirmed male embryos that was induced with Y-bearing semen to confirm sex ratio only. Total 96 blastocysts derived from female bearing semen were transferred into synchronized recipients and then confirmed 42 recipients (43.8%) pregnancy rate, 36 offspring (37.5%) and 91.7% female sex ratio (33 female vs. 3 male offspring). Taken together all data, elite dairy female offspring could be produced effectively by in vitro production system between pre-selected x-bearing semen and OPU derived oocytes that would be influential breeder in the breeding of dairy farm to increase effectively elite dairy offspring ratio as well as net income in the dairy farmer.

The present study is designed to compare the mortality and potential years of life lost of colorectal cancer between OECD countries and Korea before (1990-1999) and after (2000-2009) to provide data of more accurate strategy of public health policy and education about cancer treatment and prevention through examining differences of changes among the OECD countries. We statistically compared mortality and potential years of life lost from 32 OECD countries including Korea, except 2 nations with inadequate data, between before (1990-1999) and after the year 2000 (2000-2009) using 'OECD Health Data 2012' using the method of paired t-test. Male mortality of colorectal cancer was increased in 8 OECD countries including Korea and the female mortality was only increased in Chile and Korea. In particular, the increased rate of mortality was significantly high in Korean male and female. Moreover, increased rate of potential years of life lost for colorectal cancer was also significantly high in Korea: the rate in Korean male was increased over three times than in Mexico (2nd rank of the increase) and the rate of female was only increased in Korea compared with other countries, interestingly. Therefore, the present study suggested that most OECD countries well controlled the incidence and treatment of colorectal cancer after 2000 but Korea did not. From these, to control future problems, the further studies for the reason of the increase of potential years of life lost in female will be needed.

This cross-sectional descriptive study investigated the influence of romantic relationships' characteristics, self-esteem and sexual autonomy on limerence in dating relationships among female college students who had or were currently engaged in a dating relationship. The data was collected through self-reported structured questionnaires from 167 female Korean college students using convenient sampling methods from November 25, 2012 to December 20, 2012. The data was analyzed using t-tests, one-way analyses of variance, Scheffe's test, Pearson's correlation coefficients, and multiple linear regression analysis with the IBM SPSS 23.0 program. The results showed that a significant difference was found in limerence according to the frequency of experiencing romantic breakup (F=4.16, p=.003), and limerence in dating relationships was negatively correlated with self-esteem (r=-.31, p<.001) and sexual autonomy (r=-.21, p=.006). Self-esteem and the frequency of romantic breakups explained 20% of limerence in dating relationships among the participants (F=8.03, p<.001). Therefore, as a strategy to solve the problems related to limerence during the period of dating, cognitive and educational interventions are needed to strengthen the self-esteem and sexual autonomy of college students who have had a high number of separations. In addition, early screening of college students with risk factors for limerence and providing problem-solving based counseling will help improve their psychological health.

The purpose of this study is to identify the physical and psycho-social effects of self-foot reflexology on female college students wearing high heels. The research design used was the nonequivalent control group pretest-posttest design. A total of sixty-eight participants were assigned to the experimental group (n=35) or control group (n=33). Data were collected at baseline and after 6 weeks and 10 weeks. The data were analyzed using descriptive statistics, the chi-square test, t-test, and repeated measures ANOVA with the SPSS WIN 20.0 program. In the analysis of the physical effects of self-foot reflexology, there were significant interactions of group by time in terms of the lower extremity edema and fatigue (p<.05). In the analysis of the psycho-social effects of self-foot reflexology, there were significant interactions of group by time in terms of the perceived health status and self-efficacy (p<.05), except for health promoting behavior. Self-foot reflexology was effective in reducing lower extremity edema and fatigue and in improving the perceived health status and self-efficacy. Consequently, self-foot reflexology as a nursing intervention was found to be a method of providing female college students wearing high heels with physical and psycho-social relief.

This study was conducted to investigate the effects of appearance stress, alcohol intake, and eating attitude on self-esteem of female undergraduate students. Participants were 150 female undergraduate students who responded to a survey conducted from March to July of 2017. Data collected were analyzed by stepwise multiple regression analysis using an IBM SPSS 23.0. The influencing factors of self-esteem were satisfaction with college life and appearance stress, and the power of the variables was 11%. The results verified that college life and appearance stress were important factors influencing self-esteem, a critical element in the personality dimension that assesses self-affirmation. Therefore, self-esteem should be improved by providing a buffer to revitalize character resources for positive self-internalization, the formation of a healthy self-image and affect regulation which can enable one to flexibly cope with situations of appearance stress. Also, external resources should be provided inside and outside of school to help university students become cognizant of an objective perspective of the various environments of college life they face, as well as to have a positive view of themselves in college life by regulating the differences between the environments they face and their individual circumstances.

This study was conducted to investigate the relationship between maximum oxygen uptake and its related factors including body measurement and vascular compliance. The subjects of our study were 43 males and 53 females aged 40 to 59 who were visited in military health center. The main results were that 1.the degree of obesity had significantly negative correlation to vascular compliance in male, and waist-hip ratio in female. 2. The degree of obesity, body mass index, waist-hip ratio and body fat percent had significantly negative correlation to maximum oxygen uptake in male, and waist-hip ratio & body fat percent in female. 3. Maximum heart rate had significantly positive correlation to maximum oxygen uptake in male, and vascular compliance & maximum heart rate in female. 4. In multiple regression analysis which maximum oxygen uptake was as dependent variable, body fat percent, vascular compliance and maximum heart rate were significant variables for both male and female. In conclusion, Maximum oxygen uptake of some rural people age 40 to 59 were affected by various factors such as body fat percent, vascular compliance, and maximum heart rate.
