The purposes of this study is to examine the degree of dysmenorrhea and self-management of dysmenorrhea in high school girls and to provide basic information for health education. This research is the contents of the characteristics and self-management of dysmenorrhea and thereby serve to provide some theoretical grounds for the health education of high school-girl students. The subjects of this study are the 376 girl students of a high school in Taegu. This study was conducted by collecting data from April 3rd to 7th, 2000. The instruments used for this study by the researcher of this study based on Choi, Myung-Ok's (1992) menstrurational symtom scale (8 items) and factors used to dysmenorrhea scale (5 items). Health locus of control is obtained from a review of references by the researcher, Sin Jae Sin (1985) translated Multidimensional health Locus of Control scale (18 items) were made by Wallston & Wallston (1976). The collected data was analysed by mean, percent, Chi-squre test, Fisher's Exact Test using the SPSS (v 6.12) and SAS program. The results of this study were as follows : 1. The characteristics of dysmenorrhea were low abdominal pain, fatigue, back pain, headache, muscle pain, diarrhea, nausea and vomiting. 2. The degree of dysmenorrhea was shown 'a few of discomfort experiment': 73%, late, leaving early and absent for school : 4.0%. 3. By means locus of control, internal health locus of control was shown 79.5% and external health locus of control was shown 20.5%. 4. The self-management of dysmenorrhea was shown 'massaging on the abdomen and bed rest' is 31.9%, 'tolerance' is 53.5%. 5. When the characteristics of dysmenorrhea was compared with demographics, low abdominal pain was significant of the number of siblings (p<.05), the family history (mother's dysmenorrhea)(p<.01) and back pain was significant of the age, family history, low abdominal pain (p<.05, p<.01, p<.01). 6. There was no significant of the locus of control. When the self-management of dysmenorrhea was compared with demographics, the age was significant (p<.05).

The purposes of this study were to investigate problems related to quality of life and to identify residents needs for the university educational program for the community residents. The data were analyzed by using $x^2$-test, F-test and multiple range test. Findings of this study provided some useful implications to develop educational programs for community people. These implications are as follows. In the aspect of home management, the need for education about time management was relatively high and the degree of time conflicts was varied to family size, educational level of house, housewife's employment status and outside work time. In the program area of economic life, education for enhancing ability to cope with unexpected events and impulsive consumption behavior, and education for money management technique and value clarification should be included. There were significant differences in the parents' role difficulties according to mother's age and income. Especially parents' role difficulties were children's social emotional development and educational activity. The major problems in management of clothing and textile products were the change of textile sensation, the poor quality of necessaries, and discoloration. This result suggests that education programs on management of clothing and textiles should be developed. In health and food management it showed that subjects were afraid of cancer, hypertension, cerebral vascular diseases in relation with food habits. Hence program of education for health and good food habits should be developed.

The environmental risks of cucumber mosaic virus resistant transgenic chili peppers with the CMVP0-CP gene on non-target organisms in the agroecosystem environments was evaluated during the periods of the chili pepper growing season (June 19, July 30, August 31) in 2007. Arthropods assemblages leaves and flowers of chili peppers were quantitatively collected by using an insect vacuum collector to compare the arthropod community structures between non-transgenic chili peppers (nTR, P 915) and mosaic virus resistant transgenic chili peppers (TR, CMV-cp, line 7). There was no statistical difference in the arthropod community structure between the two types of crops, nTR and TR, at the same season, although the species richness and Shannon's index were somewhat different among seasons; indicating no effects of genetically modified peppers on the arthropod community. However, further studies were required to conclude more concretely for the potential environmental risk of the transgenic chili pepper of CMV-cp.

The aim of this study is to identify whether the domestic violence experience of children has an impact on their game addition and to verify the direct effects and moderating effects of social support. The survey was conducted to the children who were 5th and 6th graders in Gwangju and Jeonnam. The responses from 328 subjects of domestic violence experience from were analyzed. The analytic results are as the following. When verifying the impact of a domestic violence experience of children on their game addiction, domestict violence was found as the key variable that has a negative impact on children's game addiction. The results indicated that children with higher levels of domestict violence more likely to have higher levels of game addiction. Furthermore, boy's addiction degree to game was higher than girls' and lower education levels of mother, higher grades were found to be associated with higher game addiction. The impact of children's social support on their game addiction was analyzed. The analytic results suggest that social support has a impact on their game addiction. In other words, higher social support means lower game addiction. The moderating effect of social support was analyzed. Social support check the moderating effect of domestic violence of children on their game addiction. The Implications of these findings were discussed.

This experiment was conducted on 60 Hanwoo calves comprising five feed additive groups, with 12 calves in each group, to determine the effects of additives at pre- and post-weaning on growth performance and blood profile. The groups were control, antibiotic (Neomycin 110 ppm), illite (2%), fermented green tea probiotics (FGTP, 0.5%), and mixed additives (FGTP 0.25%, illite 1% and licorice 0.1%). The calves were offered experimental pellet feeds ad libitum and after one month were supplied with imported timothy hay. They moved freely within the group and suckled their mother' milk during the pre-weaning stage (birth to 3 months) and were separated from their dam during the post-weaning stage (4-5 months). During the pre-weaning stage, the highest average daily gain (ADG) was recorded in the antibiotic- and mixed additive-fed groups followed by FGTP, control and illite groups. In the post-weaning stage, significantly higher total weight gain and ADG were recorded in both the FGTP and mixed additive groups compared to the other groups (p<0.05). Feed efficiency of mixed additive- and illite-fed calves were almost similar with antibiotic-fed calves compared to the other two groups, but the ADG was lowest in illite-fed calves during the pre-weaning stage. In contrast, post-weaning calves fed FGTP and mixed additives showed better feed efficiency. The values of hematological indices, differential leukocyte count, blood proteins and immunoglobulin among the additive-fed calves were not significantly different (p>0.05), although hemoglobin and hematocrit values were lower in FGTP compared to control, but similar in mixed additive and antibiotic groups. These results indicate no detrimental effects of feed additives on the blood profile of calves at both pre- and post-weaning age. Serum albumin in post-weaning calves of all feed additive groups were similar but significantly lower (p<0.05) than in the control group. Post-weaning, IgM was significantly lower (p<0.05) in illite-fed calves compared to other treatment groups, but there was no difference at pre-weaning. Considering all factors, the mixed feed additives and FGTP can be the replacement feed formula for antibiotic for Hanwoo beef calf production, especially when used post- weaning.

A wide range of challenges and obstacles still exist for "mumpreneurs" in creating or developing their business ventures. It is important to investigate the factors regarding why many mothers choose to become self-employed and partially abandon the benefits offered by traditional employment. This study focus on the individual, but an implied positive relationship also exits between motivational factors and mumpreneurs in Korea. Thus, four factors in this study - push, pull, environmental, and financial factor - raise the practical implications regarding the motivational factors of women entrepreneurial challenges in Korea. This study's findings also consider the nature and changes of Korean mumpreneurs' motivational factors, their challenges, and attitudes as business owners in Korean labor markets. This study's findings suggest that a combination of push and pull factors could similarly trigger new business ownership. The empirical contrast in such variables as motivations or barriers to mumpreneurship, in realities provide a superior understanding of women's tendency or willingness toward business creation, as they struggle to survive in the Korean labor market. They tend to start their own businesses to gain more responsibilities in both work and their families, and want to manage their own lives to contribute as capable members of society. Therefore, any Korean mother, regardless of any industry-specific experience, wants to use entrepreneurship as a shortcut to satisfy her need for self-fulfillment. The general motivational factors for becoming a mumpreneur exist among both external and internal situations. The circumstances beyond their control, such as job termination or unemployment, compel these mothers into the workforce due to their responsibility toward their families, but they simultaneously dream of self-achievement and development. Most mumpreneurs in Korea also want to demonstrate their potential and achieve societal recognition as well as increase in property.

Efforts have been made to explore the possibility of using garlic as an antimicrobial therapeutic agent since garlic extract and its individual sulfur compounds show antimicrobial activities against all kinds of microorganisms including bacteria, molds, yeasts and protozoa. Staphylococcus aureus has been the most studied bacteria along with many other Gram positive and negative pathogenic bacteria, including species of the genera Clostridium, Mycobacterium, Escherichia, Klebsiella, Bacillus, Salmonella and Shigella. Candida albicans has been the most studied among the eukaryotic microorganisms. A pathogenic protozoa, Giardia intestinalis, was also tested. All the microorganisms tested was inhibited by garlic extract or its sulfur components. Garlic has been known to be growth inhibitory only when fresh garlic is crushed, since allicin-generating reaction is enzyme-catalyzed. Allicin is known to be growth inhibitory through a non-specific reaction with sulfhydryl groups of enzyme proteins that are crucial to the metabolism of microorganisms. Another plausible hypothesis is that allicin inhibits specific enzymes in certain biological processes, e.g. acetyl CoA synthetase in fatty acid synthesis in microorganisms. Allicin transforms into other compounds like ajoene and various sulfides which are also inhibitory to microorganisms, but not as potent as their mother compound. It is reported recently that garlic heated at cooking temperatures is growth inhibitory especially against yeasts, and that the growth inhibitory compound is allyl alcohol thermally generated from alliin in garlic.

This study examined the trajectories of the marital satisfaction of parents to classify its latent classes and how marital satisfaction influences the behavioral problems of their children between the identified latent classes. The 1st to 8th and 10th data from the Korea Child-Adolescent Panel Survey were analyzed using the latent class growth analysis and BCH method. First, based on the mother's trajectory of marital satisfaction, five latent classes were identified: 'low constant', 'intermediate constant', 'temporary increment-constantly decrement', 'high constant, and 'highest constant'. At the same time, based on the father's trajectory of marital satisfaction, four latent classes were identified: 'increment', 'intermediate-slightly decrement', 'high-slightly decrement', and 'highest constant'. Second, mothers with low marital satisfaction had more children with behavioral problems, and their influence had more problems with internalized behavioral problems. These problems progressed to externalized behavioral problems as they grew. Both internalized and externalized behavioral problems were also found between the identified latent classes of the father's marital satisfaction. Children of fathers with low marital satisfaction showed more behavioral problems. These findings suggest that the marital satisfaction of parents is an important variable that can influence the behavioral problems of their children.

Familial hypokalemic periodic paralysis (hypoPP) is a rare inherited channelopathy that often presents with episodic weakness accompanied by hypokalemia. Thus far, mutations in the gene encoding two ion channels (CACNL1A3, L-type calcium channel alpha-1 subunit and SCN4A, a sodium channel type IV alpha subunit) have been identified. Several cases of familial hypoPP in children have been reported in Koreans, but there are only a few cases with identified mutations. We report a 12-year-old boy and his affected mother with hypoPP who has a heterozygous G to A substitution at codon 1239 in exon 30 of the CACNL1A3 gene that causes a change from arginine to histidine (Arg1239His, CACNL1A3). This mutation is common among Caucasians; however, it has not yet been reported in Koreans. The patients were treated with oral acetazolamide and potassium replacement and were instructed to avoid precipitating factors. After the medication and lifestyle modification, the paralytic attacks significantly decreased.

This study was performed by questionnaire to investigate the recognition and prospect for Korean traditional Pyebaeck Foods. The subjects of this study consisted of 621 housewives in Daegu area. The results were summarized as follows: The most people(94.2%) had ever seen Pyebaeck refreshments before, and most had seen them in wedding halls(62.5%). The reason they do prepare Paebaek refreshments was “it's tradition”(44.9%), and they considered this tradition as a public moral. The peoples who had prepared Pyebaeck refreshments at home consisted 51.0% and those who had purchased at caterer was 59.5%. The reason for preparing the refreshments at home was usually “it's true-hearted”(48.8%) and the reason for hiring specialists was “it's more convenient”(38.7%). Opinions about cooking method were mostly “complicated”(79.8%), and the knowledge score for cooking methods was low in 2.80. 31.3% of respondents reported inheriting their recipes from their mother. 43.3% of the respondents thought it would be “transmitted only a part” on prospects for Pyebaeck refreshments. 31.5% of the respondents said the improvement plan should be “focused on development of various Pyebaeck refreshments with modern senses” and 30.4% that the industralization should be effected through “publicity activities and education about its excellence”. People had to experience the Pyebaeck in the right way and to understand its real meaning better in order not to consider it as an evil custom, empty formality and vanity.
