Governments and private companies have established various local entrepreneurial infrastructure institutions in most regions in order to reduce youth unemployment, and boost youth entrepreneurship and regional employment. However, previous studies has been limited to explore the impact of the entrepreneurial infrastructure institutions on the willingness of start-up entrepreneurs. Thus, the main purpose of this study is to fill in the gaps of the research, identify the effect of the entrepreneurial infrastructure institutions on regional employment focusing on the Partner Squares which are entrepreneurial infrastructure institutions in several regions and established by N company, and set a foundation for further research regarding the effectiveness of the entrepreneurial infrastructure institutions. In order to verify the effectiveness of the Partner Squares on the local employment, we use the raw data of the Economically Active Population Survey (Statistics Korea) and analyze the effectiveness by using the Difference-in-Differences model. The main findings are as follows. While the Partner Square Seoul has not statistically influenced on the employment of local youth workers, the Partner Square Busan has increased about 3% of the average number of employees (575 thousand) from May 2017 to July 2019, increasing the number of local youth workers by 17,000. Also, after the establishment of the Partner Square Gwangju, the institution has increased 4,500 local employees, which is about 1.7% of the average number of employees (267,000) from September 2018 to July 2019. This implies that the Partner Squares provide a variety of effective start-up education programs and networks for pre-starters and founders in the region, thereby helping them to grow and boosting the local employment. An important implication is that by using government statistical data, we find roles of entrepreneurial infrastructure institutions to revitalize local economy and employment. In future studies, studies need to be conducted considering various exogenous variables that can affect local employment, such as the government industrial policies and entrepreneurial infrastructure institutions other than the Partner Squares.

The purpose of this study was to investigate the sweets preference, food frequency, dietary habits, and nutrition knowledge of middle school students who like sweets. A survey instrument consisted of a self-administered questionnaire, a food frequency questionnaire, and anthropometric measurements. Three hundreds thirty five students aged 13 to 15 years old were divided into two groups, Sweets Liking Group (SLG) and a control group based on the subjects' scores for dietary habits, sweets preference, and food frequency. For dietary habits, the score for meal regularity was significantly lower in the SLG group compared to the control (p<0.001). In addition, the SLG group was more likely to skip breakfast (p<0.001), eat inadequate amount of meals (p<0.001), and consume yellow-green vegetables less frequently (p<0.001) than the control. The subjects' nutrition knowledge was assessed using 20 questions representing five categories, including functions of nutrients, nutrition and health, food pyramid and food groups, healthful snacking and the right dietary attitude. The total scores for nutrition knowledge indicated that the SLG had a poorer nutrition knowledge for all five categories than the control (boys p<0.05, girls p<0.01). For food frequency, the SLG consumed more sweets but less grains, cereals, fishes, beans, vegetables, and milk and milk products than the control (p<0.001). Strong positive correlations appeared between sweets preference, sweets frequency, and sweets-related dietary habits; and all were negatively correlated to nutrition knowledge. Sweets frequency was negatively related to meal regularity, breakfast consumption, meal adequacy, and balanced meals. The findings suggest that nutrition education is necessary to improve the dietary pattern, especially sweets consumption, of Korean young adolescents.

This study was conducted to investigate treatment tendency and dental caries occurrence after receiving insurance coverage for pit and fissure sealing. Data were obtained from statements for insurance payments received by the Daejeon branch health insurance review and assessment service from December 2009 until December 31 2014. As to the Pit and Fissure Sealing current state by year, there was most a lot of the number of examinee and the treatment number of teeth in 2010. The per capita average treatment number of teeth was highest (3.39) in 2013. As to the result that it analyze the first molar Pit and Fissure Sealing in 2010 according to the general feature, man was high than the woman, it showed up by age in the age of 7 most highly, and the summer was the highest among by season. The upper jaw left first molar was the most common location, although the upper jaw on the right side first molar, lower jaw right side first molar, and lower jaw left first molar were also affected. In 2010, the procedure was conducted more in the upper jaw right side first molar and enforces the recharge since 2011 to 2014, men were treated more than women, the recharge which is the most abundant in the age of 7 was performed by age, and the procedure was performed more during summer than in other seasons. It is forecasted that at August, 2015 most high demand shows according to the result that it predicts the tooth treatment number until December 2015 based upon the treatment number of teeth from December 2009 until November 2014 and be reduced in comparison with the year 2014. Thus, tooth brushing alone is not sufficient to prevent dental caries. Indeed, conducting pit and fissure sealing in infants and toddlers, as well as elementary middle and high school oral health centers is expected to be effective at preventing dental caries.

Purpose : Through a survey undertaken among doctors practicing pediatric patients in primary medical facilities on nutrition during infancy, the present study was done to determine whether these doctors were giving appropriate advice on infant nutrition. Methods : We visited pediatric specialists(group one) and non-pediatric specialists or general practitioners(group two) who were practicing in Daegu to ask them to fill out a questionaire on infant nutrition. Results : When 10 points were given to each question for a total of 100 points, the results of the evaluation showed that the score in group one was $73.0{\pm}15.8$ points and $45.1{\pm}18.4$ points in group two, showing a significant difference. No statistical difference was seen in the scores between non-pediatric specialists and general practitioners. Each answer to each question on the feeding period of breast milk, on loose stools during breast milk feeding, methods to deal with jaundice during breast milk feeding, choice of commercial baby food, criteria on directing soy milk, and criteria of guiding infant cereal was different between group one and two. Conclusion : The results of the present investigation showed that specialists in other fields or general practitioners were giving inappropriate advice on nutrition during the infant stage compared with pediatric specialists; thus, we need to confirm methods to prevent inappropriate consultations by specialists of other fields, together with continued education of pediatric specialists.

This experiment was conducted to study the effects of Korean ginseng and tocopherol on serum testosterone level, protein metabolism and swimming endurance in rats. Powdered ginseng (2.5 g/kg) and ${\alpha}-tocopherol$ (250 mg/kg) were added directly into the basal diet of rats feeding for 6 weeks. The serum testosterone level of ginseng-treated rats had no difference from that of control rats, but the level was slightly increased in tocopherol-treated rats. In the case of ginseng-treated rats, there were no significant difference in the contents of albumin, ${\alpha}_1-globulin$, ${\alpha}_2-globulin$, ${\gamma}-globulin$ and A/G ratio compared with those of the control rats, however, the levels of total protein and ${\beta}-globulin$ were increased significantly(p<0.005). Total protein value of tocopherol-treated rats was higher than that of the control rats(p<0.005). In contrast, albumin content was slightly decreased. The contents of ${\alpha}_1-globulin$, ${\alpha}_2-globulin$, ${\beta}-globuiln$ and ${\gamma}-globulin$ were higher in the rats fed tocopherol diet that those obtained from the control rats. Accordingly A/G value was markedly decreased (p<0.001). In swimming endurance test, both Korean ginseng and ${\alpha}-tocopherol$ did not appear to have any effect on rats' stamina.

Evaluation of the removal efficiencies of Fe(II) by reactive sand media coated with manganese (MCS), iron (ICS) and both of iron and manganese (IMCS) was investigated as functions of solution pH ranging from 2 to 9, reaction time and concentration of Fe(II) in a batch reactor using each reactive medium and additional oxidants such as $KMnO_4$ and NaOCl. When only Fe(II) was present in solution without any reactive medium, removal of Fe(II) was quite low below pH 5 due to a slow oxidation of Fe(II) and/or negligible precipitation but greatly increased above pH 5 due to a rapid oxidation of Fe(II) and subsequent precipitation of oxidized Fe species. ICS showed negligible efficiency on the removal of Fe(II) through adsorption. However, an efficient removal of Fe(II) was observed at low solution pH in the presence of IMCS or MCS through rapid oxidation and subsequent precipitation. Removal efficiency of Fe(II) by IMCS in the presence or absence of NaOCl was quite similar. Removal rate of Fe(II) by IMCS and additional oxidants gradually increased as the solution pH increased. From the kinetic experiments, removal pattern of Fe(II) was better described by pseudo-second-order equation than pseudo-first-order equation. A rapid removal of Fe(II) using IMCS in the presence of $KMnO_4$ was observed in the first 10 min. The initial removal rate of Fe(II) using $KMnO_4$ was 14,286 mg/kg hr. In case of using NaOCl, the removal of Fe(II) occurred rapidly in the first 6 hrs and then reached the near-equilibrium state. Removal of Fe(II) on IMCS was well expressed by Langmuir isotherm and the maximum removal capacity of Fe(II) was calculated as 1,088 mg/kg.

A survey was carried out in Seoul Metropolitan area during December of 1993 and January of 1994. The objective of the survey was to provide a useful information for the development and improvement of recycling policies, regulations and systems in Korea. Of the 782 individuals contacted, 473 individuals completed and retured surveys, of which 437 were usable. The results were analyzed using a statistical package SAS(Statistical Analysis System). The results indicated that 86% of apartment area has recycling bins, while only 33% of individual house(detached dwelling) area has those. About half of the respondents felt that food waste is the major source of household waste. The most serious problem to recycle more household waste is to provide space to store recyclables at the source. The majority of Seoul Metropolitans(78.5%) are willing to participate in recycling programs, while 14.4% want to participate only when there are economic incentives or benefits. Respondents who want economic incentives appeared to be low income people. 66.1% of total respondents said that they do not use disposables. However, only 53,0% among respondents under 30 years old answered they do not use disposables. People who graduated from middle high school only and are under 30 years old have tendency to dispose of used milk cartons without rincing and drying, while those who are over 40 years old and graduated from university prefered to rinse and dry used milk cartons before disposal. Regarding disposal of newspapers, only 43.9% of the total respondents separated newspaper from other types of used paper. In the case of alumium cans, 22.5% of the total respondents answered that used aluminum cans are not recyclables. Much higher portion (30. 4%) of the respondents who graduated from middle high school only felt that aluminum cans have no value to recycle. The results indicated that education and information regarding recycling are highly desirable.

The present study estimates intake levels of dietary fiber (DF) in Korean adults aged 20 and over, using a newly established dietary fiber database for 3,149 food items, as well as 24-hour recall method data from the 2001 Korean National Health and Nutrition Survey. Dietary fiber intake and food groups are analyzed by gender, age, and region. The average dietary fiber intake, per capita of Korea was estimated to be 12.24g/1,000kcal or 23.58g/day. Calorie-based dietary fiber intake for 20-49 year-old-Korean males, 20-29 year-old females, and the adults who resided in metropolitan areas was under the Adequate Intake for DF, 12 g/1,000 kcal. Further, the dietary fiber intake after adjusting energy intake in people over 75 year-old was estimated to be 75% of AI. Vegetables, cereals and fruits were three major sources of DF for Korean, making up approximately 75% of DF. Regarding the subjects of this study, major sources of dietary fiber were Kimchi and well-polished rice, which supplied 13.98% and 9.16% of total dietary fiber intake, respectively. The result of this study could contribute to the establishment of DRIs for dietary fiber, after adjusting energy intake for Korean aged 75 years and over. The beneficial health effects of DF and the necessity of nutritional education in this area should be continuously emphasized concerning 20-29 year-old people and metropolitan adults.

Purpose: The purpose of this study was to investigate the consumption behaviors of sugar-sweetened beverages and blood lipid profiles according to food-related lifestyles of adults in Incheon. Methods: Subjects were recruited from 19 to 64 year old adults residing in Incheon who visited for the purpose of a health examination at D hospital. A total of 110 subjects consented to participate in this study and to allow their health examination records to be used at D hospital. Data were collected using self-administered questionnaires and anthropometric data, and blood lipid profiles were collected from health examination records. Statistical analysis was performed using the SPSS 20.0 program. Results: In the factor analysis, food-related lifestyles were categorized into four factors: planned purchase seeking, taste seeking, well-being seeking, and convenience seeking. Using the K-average clustering method, food-related lifestyles of subjects were categorized into two groups: health and rationality-oriented group (HRG) and convenience purchase-oriented group (CPG). Average total scores of sugar-related nutrition knowledge in the HRG were significantly higher compared to the CPG, and average scores of consumption habits regarding sugar-containing foods in the HRG were significantly lower compared to the HRG. When subjects chose sugar-sweetened beverages, the CPG showed a significantly higher frequency of checking food labeling and considering nutrition compared to the CPG. Drinking frequency of carbonated beverages in the CPG was significantly higher compared to the HRG. Conclusion: There were significant differences in sugar-related nutrition knowledge and consumption habits of sugar-sweetened beverages between the two food-related lifestyle groups. These results could be useful for establishing guidelines for reducing consumption of sugar-sweetened beverages. In addition, it is necessary to continue sugar-related nutrition education by considering the food-related lifestyles of adults.
