A numerical variation and abnormalities were studied on egg bags and embryos of Korean salamander, Hynobius leechii from agricultural habitat. The teratogenic and toxic effects of fungicide benomyl were also investigated with early embryos from non-agricultural habitat. We collected 144 egg bags from agricultural region, and 3418 of early embryos were contained. The lengths of egg bags were varied from 10 to 23 cm and the most frequent length was 19 cm. The number of embryos was varied from 7 to 43, and the most frequent range was 22 to 26. Spontaneous abnormalities were occurred in 406 embryos among 116 egg bags, and 24 kinds of external abnormalities were found. Individuals showing severe external defect were histologically studied and they showed optic dyspalsia, thyroid carcinoma, somatic muscular dysplasia, partial biaxial structure, decrease of red blood cells in the heart, cephalic degeneration and intestinal dysplasia. 385 embryos from non-agricultural region were exposed to 200 nM${\sim}$ 1 ${\mu}$M of benomyl at blastula or gastrula for 12 days. All embryo were dead in the concentration of 1 ${\mu}$M (LD$_{100}$) and 75% of embryos were dead in 800nM of benomyl. Speciflc effect due to benomyl was acrania or cephalic dysplasia and this restult suggests that the benomyl inhibit stongly to the development of neural tissue. These abnormal developments may be caused by antimitotic action, inhibition of tubulin complex, destruction of microtubule, inhibitions of neurulation and closing of neural fold, and by the inhibition of the movement of neural crest cells.

The purpose of this study was to investigate the dietary behavior, health-related lifestyles and nutrient intake status of college students according to physical activity levels. The physical activity levels were measured using the Korean version of the International Physical Activity Questionnaire (IPAQ) short form. The subjects of this study were 438 college students (243 males and 195 females) in Incheon area and were divided by gender and by physical activity levels, which included low, moderate and high physical activity groups. The average age of male and female students were 23.7 and 21.0 years old, respectively. The prevalence of the low physical activity group was 11.5% for males and 30.8% for females and that of the high physical activity group was 38.7% for males and 22.6% for females. According to the criteria for obesity in Asia-Pacific region, 39.1% of the males and 64.1% of the female students investigated were in the normal range of BMI and 30.9% of the males and 4.6% of the female students were in the obesity category. However, percent of body fat in the female students was significantly higher than that of the male students. The soft lean mass of the high physical activity group was higher compared to the other groups. In the low physical activity group, frequency of “eating out” was lower compared to the other groups. The average consumption of energy was 74.4% for males and 80.1% for females of the estimated energy requirement (EER). The mean intakes of vitamin C, vitamin B2, folic acid and Ca were 67.3%, 84%, 52.7% and 36.7% for males and 64.8%, 99.9%, 51.1% and 40.1% for females of recommended intake (RI), respectively. Therefore, it was necessary for obesity prevention as well as health promotion to increase physical activity and to eat an adequate, balanced diet in female college students.

This is a cross-sectional descriptive correlation study that aimed to understand the relationship between the level of sexual contacts during the dates and psycho-social factors in teenage girls who have or had boyfriends. The purpose of this study was to describe the relationship between sexual contacts and self-esteem and self- assertiveness. The subjects of the study were 6,130 teenage girls who have or had boyfriends. They were selected convienently 12,733 teenage girls from 254 secondary schools located in 7 large cities and 9 provinces in Korea. A structured questionaire was used it included items one general characteristics, the levels of sexual contacts, self-esteem and self-assertiveness. Seven levels of sexual contacts were rated they were holding a hand, putting arms around each other's shoulders, kiss, french kiss, touching breast, petting genitalia, and sexual intercourse during the dates. Self-esteem and self-assertiveness were measured by the "Self-esteem scale" of Rogenberg (1971) and the questionaires developed by S. B. Chang et al(2000), respectively. The self-reported questionaires were collected from October 2, to October 28, 2000 and analyzed by using SPSS 10.0 Program. The data were analyzed by descriptive statistics, reliability, One-way ANOVA with Duncan method & Scheffe method. The results of the analysis were as follows. 1.An average Percentage of the respondents who have (46.1%) or had (53.9%) boyfriends was 48.1% (n=6,130) and the most common sexual contact during the dates was french kiss (26.7%, n=1,634). While 7.5%(458) of respondents had a sexual intercourse, 13.7%(842) of respondents didn't have any sexual contact during the dates. 2. Distribution of starting point of the first sexual contact demonstrates that 1,950 respondents (31.8%) held partner's hand at the first date and 1,367 respondents (22.3%) put arms around each other's shoulders at the 2nd or 3rd date. Sexual contacts such as kiss, french kiss, touching breast, petting genitalia, or sexual intercourse were experienced mostly at the later than the 10th date. However, surprisingly large number(1.7%) of respondents had genital contact and sexual intercourses at the first date. 3. The means of self-esteem and self-assertiveness socres of the respondents who have or had boyfriends are 27.43$({\pm}4.03)$ and 17.96$({\pm}2.55)$, respectively. The range of scores for self esteem was 10-40, 40 with most self esteem. The range of scores for self assertiveness was 7-21, 21 with most self assertiveness. 4. As sexual contacts proceeded, the means of self-esteem and self-assertiveness values decreased. In detail, the respondents having no or light sexual contacts (kiss, putting arms around each other's shoulder, holding a hand) had similar self-esteem values($p{\leq}0.05$). However, ones having relatively intensive sexual contacts (french kiss, touching breast) showed significantly lower self-esteem values($p{\leq}0.05$). Same trend has been obtained for self-assertiveness value. 5. The higher values of self-esteem and self-assertiveness values the respondents had, the later they started the moderate sexual contact (kiss, french kiss) during the dates. Interestingly, among the respondents having intensive sexual contacts (petting genitalia, sexual intercourse) during the dates, those who experienced the such contacts at the first date or later than 10th date have higher self-esteem and self-assertiveness values than one experienced the such contacts during the 2nd$\sim$9th dates, giving U-shape curve. 6. There was a significant relationship between self-esteem and self-assertiveness in girls who have or had boyfriends($P{\leq}.001$). In conclusion, the research shows that self-esteem and self-assertiveness values are significantly related with the sexual contacts of the teenage girls who have or had boyfriends. These results strongly suggest that proper sex education program for teenage girls should contain the program on improving the self-esteem and self-assertiveness. We believe that sex education program is the one of the best ways to prevent the unwanted sexual contacts and pregnancy of teenage girls.

The research investigates the attitudes toward children among mothers young children and maternal grandmothers, focusing specifically on the ideal number of children, gender preference, old age security and positive and negative values of children. A total of 442 respondents, consisting of 221 young mothers (average age of 35) and 221 maternal grandmothers (average age of 63) completed a questionnaire developed by Kim, Park and Kwon (2005). The reliability of the scales ranged from Cronbach α of .78 to .91. The results are as follows. First, as for the ideal number of children, young mothers reported that they would prefer two children, while grandmothers reported that they would prefer four children. As for the ideal number of male child, young mothers reported that they would prefer that they would prefer one son, while grandmothers reported two sons. Second, as for the gender of the child, young mothers did not show a gender preference, while grandmothers stated that at least one child should be a son, especially if it is the only child. Third, grandmothers had higher expectation of old age security in their male child than young mothers but two groups did not show any difference for the female child. Fourth, as for positive values of children, young mothers were more likely to emphasize personal aspects (i.e., psychological pleasure and happiness) and family cohesiveness, while grandmothers were more likely to emphasize social aspects (i.e., continuing the family line and old age security. As for negative values of children, young mothers were more likely to emphasize personal aspects (i.e., parental role and responsibility), while grandmothers were more likely to emphasize social aspects (i.e., family conflict and relationship). Fifth, as for factors that influenced the number of children that they decided to have, young mothers were more likely to report negative values of children (i.e., financial constraints), while grandmothers were more likely to emphasize positive values of children (i.e., continuing the family line).

Purpose: This study aimed at understanding meal kit purchasing behavior and investigating its relationship with the Nutrition Quotient (NQ) of young adults. Methods: We conducted a survey on adults in their 20s and 30s covering their meal kit purchase experience, satisfaction, recognition, and purchase intention, and examined the relationship between the meal kit purchase and their NQ from February to March 2021. Results: Among the 404 subjects, 37.9% of males and 48.0% of females had experience in purchasing a meal kit (p < 0.001). The highest response indicated that the purchase cost of meal kits was 10,000-20,000 Won at a time, and the frequency of purchase was less than once a month. The convenience of cooking was the main reason for the purchase of meal kits, which were consumed mainly in the evening with family. The satisfaction with the purchase experience of a meal kit was rated 3.6 points for males and 3.7 points for females out of 5 points, and the satisfaction experienced by women was significantly higher than men in terms of freshness of ingredients, packaging design, and adequacy of the quantity of content (p < 0.05). Recognition of the meal kit was rated 3.5 points for males and 3.7 points for females out of 5 points. The purchase intention of the meal kit was rated 3.8 points for those with prior purchase experience, 3.2 points for the non-experienced, 3.3 points for males, and 3.6 points for females out of 5 points each (p < 0.001). The NQ score of dietary behavior in females with experience of meal kit purchases was significantly higher than non-experience (p < 0.05). Conclusions: The dietary behavior of female showed a significant difference by the meal kit purchase experience. It is necessary to understand the consumers' meal kit purchasing behavior to enable the development of various health-oriented meal kit products.

We investigated foodservices and levels of their satisfaction from parents of children in kindergartens with and without dietitians. Foodservice facilities consisted of kitchens and cafeterias for all kindergartens with a dietitian (KWD) and only kitchens for all kindergartens without a dietitian (KWOD) (p<0.001). Children consumed lunch in a lunchroom for all KWD and in a classroom for all KWOD (p<0.001). The person in charge of the diet menu was a dietitian for all KWD and a director for 52.2% of KWOD (p<0.001). About 48% of total kindergartens were served different amounts according to the child's age and body size. About 30% of parents from total kindergartens responded that a difficulty of foodservice management was children's safety while distributing the lunch. The majority of respondents claimed that foodservices need a more balanced menu and active instructions on proper dietary habits. Parents who visited and participated in foodservice were significantly higher from KWD than KWOD. Also, the desire to participate in foodservices was significantly higher in the parents from KWD (p<0.01). Sixty one percent of parents from KWD and 19% of parents from KWOD considered foodservices when choosing a kindergarten (p<0.001). The satisfaction in foodservices of parents from KWD was significantly higher from all points of view in terms of the quality of foodservice, nutrition, and hygiene. In conclusion, we found that foodservices and their levels of satisfaction from parents of kindergartens with dietitians were better and higher than those without dietitians. Therefore, all kindergartens should consider having a dietitian exclusively in charge of foodservices.

The treatise is a follow-up thesis of "The Archival Management : destination of its education" published by The Research Institute for Korean Archives and Records in June 17, 2000, and it was written to secure its original temper of the "Archival Management" which has established at first as the domestic collegiate educational course. Presently, we are mixed up for interpretation of terminology by facing unfamiliar words: such as, Archives, Documents, Manuscripts, Records / Archival Management, Archival Preservation / Archivist, Archival Conservator, Manuscripts Curator and Record Manager. Also, tile treatise has confirmed scholars' various opinion about its education and curriculum not only domestic but overseas scholars, and examined realities and course of studies of 4 overseas countries, and also have purpose to pursue domestic universities' actual condition of curriculum and its reform measure. And since dispositon of Archivist and the professional organization of the Archivist was based on the Laws, therefore, establishment of an educational institution for Archival Management from now on will be expanded more and need to be accelerated. Accordingly, the universities that already established or to be established from now on, shall be needed educational quality and its contents to be ascended. Its concrete plan is as follows : (1) Now, disarranged archive and record words, and to make publish 'Glossary of Archives & Records' as soon as possible. (2) Remind the substance of the Record and Archival Management and its sphere again and need to be considered alteration of the studies' name. (3) There needs to establish the role and establishment of conception of Archivists. (4) Refer to the theory and practical educational method of overseas professional Archivist Scholars, but to be needed to develop the curriculum which is accorded with am tradition and way of thinking. (5) Confer for development of teaching materials and educational method jointly through 'Academic Society', and there needs reorganize the subject which is fit for each university's characteristics. (6) Recently, "Cultural Resources Studies" for research specialization which has established in Graduate School of Tokyo University was very useful to us. We also need to be considered such establishment of process.

Purpose: It is reported that most senior people consume a high carbohydrate diet, while a high carbohydrate diet could contribute to the risk of chronic disease. The aim of this study is to determine whether a high carbohydrate diet can increase the risk of chronic disease in elderly Koreans. Methods: Using the 2007-2009 Korean National Health Nutrition Examination Survey data, out of a total of 3,917 individuals aged 65 and above, final 1,535 subjects were analyzed, divided by dietary carbohydrate energy ratio into two groups of moderate carbohydrate ratio (MCR, 55-70%) and excessive carbohydrate ratio (ECR, > 70%). All data were processed after the application of weighted value, using a general linear model or logistic regression. Results: Eighty one percent of elderly Koreans consumed diets with carbohydrate energy ratio above 70%. The ECR group included more female subjects, rural residents, lower income, and lower education level. The ECR group showed lower waist circumference, lower diastolic blood pressure, and lower frequency of consumption of meat and egg, milk, and alcohol. The intake of energy and most nutrients, with the exception of fiber, potassium, vitamin A, and carotene, was lower in the ECR group compared to the MCR group. When analyzed by gender, the ECR group showed lower risk of dyslipidemia in male and obesity in female subjects, even though the ECR group showed low intake of some nutrients. No difference in the risk of hypertension, diabetes, and anemia was observed between the two groups in male or female subjects. Conclusion: This result suggested that a high carbohydrate diet would not be a cause to increase the risk of chronic disease in the elderly. Further study is needed in order to determine an appropriate carbohydrate energy ratio for elderly Koreans to reduce the risk of chronic disease.

Objectives: This purpose of this study was to make clear the fitness to data of the causality model related to father's child-rearing participation in a double-income household. Methods: Subjects of this survey consisted of the fathers of 2,006 households that use 21 day-care centers and 4 kindergartens whose cooperation was received via the city government departments that have jurisdiction over day-care centers and kindergartens in cities A and B in prefecture I and in city C in prefecture II (city A: 499 households; city B: 1,113 households; city C: 988 households). The surveyed items consisted of the father's age, the father's educational history, the number of children, the age of the youngest child, the father's parental-role awareness, the father's daily working hours, the father's return-home time, and child-rearing participation by the father. Results: The fit indices were found to be CFI = 0.912, GFI = 0.948, and RMSEA = 0.082. Regarding the path coefficients, the path coefficient of the pathway from the age of the youngest child to the father's parent positivity (0.08) and the path coefficient of the pathway from the father's parent positivity to child-rearing participation (0.19) were both at statistically significant levels. Also, the father's return-home time and the working hours, which were considered as disincentives exhibited a direct effect on child-rearing participation without being influenced by the father's parent positivity or parent negativity. The path coefficient of the pathway from return-home time to child-rearing participation was -0.43, and the path coefficient of the pathway from working hours to child-rearing participation was -0.13. The value of the path coefficient expressing the relationship between the return-home time and working hours was 0.80. Conclusion: Authors infered that it'll be the basic material to build a generation mechanism about vanity and father's child-rearing participation appropriately as a result of this research.

To achieve the age of 30,000 dollars GNP, The business with speed will hold a more crucial point than the business with scale, and the mass consumption market will be transformed and changed into the niche market. Moreover, it will not be easy for the company without the peculiar and creative technology to survive in the severe competition. Under these circumstances, The innovative company which knows how to use this new paradigm will select the better position in the changing market. Innovation type SMEs are contributing in maintaining the international competitiveness of domestic economy by serving high-tech and the promotion of employment. Also, Innovation type SMEs have the most important economic leverage in our domestic economy. It's a source of the growth in domestic economy. Therefore, A lot of countries have been trying to support innovation type SMEs (with a small capital and high-tech). And many countries also try to protect and promote the innovation type SMEs. Especially the Korean government is also promoting innovation type SMEs in many ways, because the future of innovation type SMEs are not bright. This study explored the three innovative SEMs and studied 1) entrepreneur characteristics, 2) the industry environment, 3) competitive strategies, and 4) resources and capabilities of organization, which have been considered as the success factors for entrepreneurial firms. This study also holds that the characteristics of entrepreneurs is one of the most important factor to impact the success of innovative SMEs. Most of entrepreneurs have started their business with high education career and field experiences and have high intentions in developing new/high techonologies, challenging spirits, and clear vision and goals. The innovative SMEs with small kinds of products and services, narrow market, and small resources are more sensitively impacted by the environment especially. But the SMEs which entered into market early could have the comparative excellencies in their market to survive and grow in the future. They also have competitive advantages in the market using differentiation strategies by technology innovation. Technology innovation and differention strategies are one of the success factors in SMEs, They entered into the niche market using this weapons. The capabilities of changing organization to their changing environment, the open orgarnization culture, the continuous employment education, and the building the organic organization are also success factors of innovative SMEs. The SMEs with the simple organization structure can make fast decisions and operate with the autonomous and flexible ways. These only three cases will not shown successful factors of over 12,000 Innovation type SMEs in Korea and this study of Innovation type SMEs is insufficient from all aspects. But this study have many implications for the future research and the entrepreneurs ready for their business.
