This study was activity of ${\alpha}-amylase$, glucoamylase of liquid Nuruk prepared using liquid Nuruk (NK) and Aspergillus kawachii (AK), Aspergillus niger (AN), Aspergillus oryzae (AO), Monascus kaoliang (MK). To investigate the relationship between the enzymatic activity and the total sugar content of liquid Nuruk depending on the types of Nuruk molds and the degree of rice-polishing. The activity of ${\alpha}-amylase$ depending on the types of Nuruk molds was shown to be 8.82, 8.72 units/mL in AN and AK treatments in brown rice liquid Nuruk at 24 hours after incubation, as the degree of rice-polishing increased, the activity of ${\alpha}-amylase$ was significantly lower (p<0.05). When brown rice was incubated in AN, it showed 8.83 units/mL at 48 hours after incubation, which was the highest activity, but there was no significantly difference (p<0.05), as the degree of rice- polishing was higher, the activity of ${\alpha}-amylase$ was lower. The activity of glucoamylase depending on the degree of rice-polishing showed 3,013 units/mL in AO treatment in brown rice liquid Nuruk at 24 hours after incubation, and the enzymatic activity was significantly higher (p<0.05). As the degree of rice-polishing increased, the activity of glucoamylase decreased, so liquid brown rice Nuruk showed the highest enzymatic activity, liquid white rice Nuruk was the lowest enzymatic activity. The highest enzymatic activity appeared in liquid Nuruk with brown rice at 48 hours after incubation. The activity of ${\alpha}-amylase$, glucoamylase showed higher enzymatic productivity as the degree of rice-polishing was lower, and there was an inverse correlation with the total sugar content.

Climatic zone in building code is an administrative district classification reflecting regional climatic characteristics. Use of Degree-Days is a fundamental method that can be used in various building design codes, analysis of building energy performance, and establishment of minimum thermal transmittance of building envelopes. Many foreign countries, such as the USA, the EU, Australia, Italy, India, China, etc., have already adapted climatic zone classification with degree-days, precipitation or amount of water vapor based on the characteristics of their own country's climate. In Korea, however, the minimum requirements for regional thermal transmittance are classified separately for the Jungbu area, Nambu area and Jeju Island with no definite criterion. In this study, degree-days of 255 Korean cities were used for climatic zone classification. Outdoor dry-bulb temperature data from the Korea Meteorological Administration for 1981~2010 was used to calculate degree-days. ArcGIS and the calculated degree-days were utilized to analyze and visualize climatic zone classification. As a result, depending on the distribution and distinctive differences in degree-days, four climatic zones were derived : 1) Central area, 2) Mountain area of Gyeonggi and Gangwon provinces, 3) Southern area, and 4) Jeju Island. The climatic zones were suggested per administrative district for easy public understanding and utilization.

This study was designed to analyze the nursing curricula in graduate programs and suggest the direction of future nursing curricula. Thirty-two nursing curricula for a master's degree and fifteen curricula for a doctoral degree from general graduate programs, fifteen nursing curricula for a master's degree from fifteen educational graduate programs, eight nursing curricula for master degree from eight out of twelve public health graduate programs, three nursing curricula for a master's degree from three administrative graduate programs, and four nursing curricula for a master's degree from four clinical nursing graduate programs, were analyzed. Consequently, It was hard to find a clear difference between the educational goals and objectives, the subjects open in nursing curricula for a master's degree and those for a doctoral degree of graduate programs. The educational graduate programs, public health graduate programs, administrative graduate programs, and clinical nursing graduate programs, each program showed ittle different in each educational goal and objective. However, because the various kinds of subjects open in each program were not based on the core curricula, the quality of the nursing curricula need to be evaluated and develope the curricula to difference are the goal and objective. Accordingly, future studies need to be focused on developing core nursing curricula reflecting the characteristics of each graduate program.
The prevalence of obesity in children has steadily risen during recent years in developed countries. Child obesity has become a major concern to health providers since it has grown to epidemic proportions over the past few decades. This study was conducted to investigate the biochemical status, dietary habits and life styles according to the obesity degree among obese children residing in the Gyungbuk area. The subjects were 148 elementary school students (boy 103, girl 45) and classified as mildly obese (n = 56), moderately obese (n = 61) and severely obese (n = 31) by the obesity index. The average body weight and height increased significantly according to the obesity degree (p < 0.05, p < 0.001). Serum cholesterol concentration came under the normal level in all groups. Serum AST activity increased according to the obesity degree but it was not significant. Serum ALT activity increased according to the obesity degree (p < 0.05). Dietary habit score was lower significantly according to the obesity degree (p < 0.01). Life style of the subjects was significantly different for the level of 'healthy state (p < 0.05)', 'body perception (p < 0.01)', 'watching TV and video (p < 0.05)', 'normal sleeping hour (p < 0.05)' and 'degree of stress (p < 0.05)' according to the obesity degree. A positive relationship between obesity index and blood pressure, ALT has been shown in the subjects. Obesity index and dietary habit scores were negatively associated. Therefore, these results suggest that a practical nutrition-exercise education program for the prevention of child obesity should be provided to elementary school children.

Bis-GMA, the representative monomer of bonding resin, contributes to the rigidity of bonding layer. Hydrophilic monomer contributes to the permeability into dentin substrates while weaken the bonding layer due to its small molecular weight. The degree of conversion also contributes to the ultimate strength of the bonding layer. This study was performed for the correlation analysis of monomer ratio and dentin bonding strength via degree of conversion. 7 experimental bonding resins were prepared with Bis-GMA, ratio from 20% to 80% by 10% increment, and hydrophilic HEMA monomer. Their degree of conversion and shear bond strength to dentin were compared with Scotchbond Multi-Purpose adhesive, and the fractured surfaces were examined microscopically. The results were as follows; 1. The degree of conversion increased when, the ratio of Bis-GMA increased from 20% to 70%, whereas it decreased when the ratio of Bis-GMA was 80%. 2. Shear bond strengths of the experimental bonding resins of 80%, 70%, 60% ratio of Bis-GMA were significantly higher than those of the experimental bonding resin of 50% ratio of Bis-GMA and Scotchbond Multi-Purpose adhesive. Lower shear bond strengths were obtained with the experimental bonding resins of 40%, 30%, 20% ratio of Bis-GMA (p<0.05). 3. Adhesive fractures were associated with the bonding resins of the lower bond strength, while cohesive fractures within the bonding resin layer were associated with the bonding resins of higher bond strength. Bonding resins with shear bond strength higher than 18MPa showed some cohesive fractures within the composite resin or within the dentin. 4. Correlations between Bis-GMA ratio and the degree of conversion (r=0.826), between Bis-GMA ratio and shear bond strength (r=0.853), and between the degree of conversion and shear bond strength (r=0.786) were significant (p<0.05).
This study was conducted to evaluate the nutrient intakes and the physical activities of mentally retarded persons (MRPs) accommodated in welfare institutions. A total of 194 cases of MRPs (130 males and 64 females) were surveyed through interviews of the 35 caregivers of the institutions during the period from March 2 to 12, 2005. The mean age of the 2nd degree is the highest, and the duration of institution stay of the 2nd degree is the longest. There were no significant differences in height, weight, but there were still significant differences in BMI by the degree of handicap. The MRPs with the 1st degree handicap consumed less nutrients than the MRPs with 2nd or 3rd degree handicaps, except for vitamins C and E. The mean activity factor was $1.737{\pm}0.422$ meaning 'active'. Among the comparative groups, the activity factor of the 2nd handicap degree MRPs was the highest. Note that the percentage of protein is the lowest in the case of the 1st degree handicap. The intake of the folic acid, in particular, was less than the Estimated Average Requirement (EAR) in case of all the MRPs while that of vitamin C, riboflavin and calcium was less than the EAR in case of $65{\sim}80%$ of the MRPs. MRPs with higher activity factors showed higher intakes of most nutrients except vitamin C. MRPs with higher marks in the 'balanced dietary habit' field showed more nutrient intakes. More consumption of vegetables and fruits by the MRPs was recommended. Also, more efficient dietary guidance was recommended for the MRPs.

This study examined the degree of life satisfaction and quality of life of elderly people living in abandoned mine regions as well as the life quality factors that affected their degree of life satisfaction. A structured survey was used to look at their degree of life satisfaction and quality of life. The subjects were 167 elderly people aged 60 or older residing in abandoned mine regions in Gangwon-do. Their quality of life and degree of life satisfaction was moderate and when they had worked for a mine for a long time, their current degree of life satisfaction was high. In addition, religion affected their degree of life satisfaction and the residential environment and pleasant environment were highly influential in their degree of life satisfaction. Therefore, to improve the degree of life satisfaction of elderly people living in abandoned mine regions, it is essential to recover their hollow areas and create a pleasant environment by organizing their residential areas and enhancing their environment.
The Purpose of this study is to analyze of Specialization and Diversity of Rural Amenity Resources Planning. It will be performed analysis of the degree of specialization and diversity in each city and district of Chungcheongnam-do Province. Specialization and diversity indices were calculated by separately category of rural amenity resources into natural, cultural, and societal resources. The results of calculating the specialization degree of rural amenity resources based on a location index showed that eleven regions (Asan City, Buyeo District, Gyeryong City, Gongju City, Nonsan City, Boryeong City, Seocheon District, Seosan City, Seajong District, Cheongyang District and Yesan City) specialized in natural resources; four regions (Geumsan District and Hongseong Distriect) specialized in cultural resources; and six regions (Dangjin District, Cheonan City) specialized in societal resources. Examining resource specialization degrees by regions, there was a high number of regions specialized in natural and societal resources while those specialized in cultural resources were the rarest. Examining the calculation results for the tendency of resource specialization degree by areas showed that, with natural and cultural resources specialized regions, the average specialization degree showed a clear distinction with a 2.19 natural resource specialization degree and a 2.05 societal resource degree; However, in contrast, areas specialized in cultural resources-with an average degree of 1.52-were judged as not being especially more specialized than the average degree of Chungcheongnam-do Province. Also, there was seen a great gap between regions with high diversity and regions with low diversity of rural amenities, and measures to solve this difference is required.
This study attempted to analyze and confirm the correlation between self-concept and the degree of satisfaction on clinical practice. The subjects of the survey were 194 junior and senior students selected from S universities by questionaire from Nov. 1 to Nov. 30, 1983 in Seoul. The collected data was analyzed by t-test, AN-OVA, Pearson correlation according to purpose of study. The results were as follows: 1. Self-concept by religion was significant (F = 4.51, df=4/185, p= .002). 2. In the motives of selecting the nursing, most of students chose the nursing depending on their altruism(62.9%), ability and aptitude(57.7%) and better opportunity of studying abroad and Setting a job(49.5%) respectively. 3. The degree of clinical practice satisfaction was low as 2.80 of a total score 4.0. The degree of satisfaction of contents(3.33) revealed to be high. Compared with the degree of satisfaction on instruction(2.77), practice hours(2.83), practice environment (3.65), and clinical evaluation(2.60) revealed to be low. Religion and choice order of the admission were not significant in satisfaction of clinical practice(t=.37, p=.715). The main hypothesis that“The more positive self concept will be, the higher the degree of satisfaction on clinical practice will be”was not supported (r= .0509, p=.240). The first sub-hypothesis that“The more positive the cognitive self-concept will be, the higher the degree of satisfaction will be”was partially supported. Because favorite-isolated self-concept was significantly correlated with the satisfaction (r=.1189, P=.005). The second sub·hypothesis that“The more positive the evaluational self-concept will be, the higher the degree of satisfaction on clinical practice will be”was not supported. As a above results, self-concept was not influenced to the degree of satisfaction on clinical practice, therefore it is required that environment, instruction method and evaluation for clinical practice should be refined and improved by clinical administrators and nursing faculties for nor-sing student's satisfaction on clinical practice.

This study was designed to investigate the effects of behavior medication and aerobic exercise on the degree of obesity, eating behavior, depression and self esteem among adolescent girls who were overweight and obese. Forty seven subjects were selected from one girl's middle school located in Seoul. Seventeen girls received the behavior modification program by joining 60-90 minute group session weekly. Behavior modification, in this study, consisted of self-monitoring, changing patterns of life style and attitudes, teaching nutrition and physical activities, and asking personal help. The aerobic exercise program was given to 16 girls 3 times per week with 60 minutes each time. Forteen girls received both behavior modification and aerobic exercise. These interventions continued for 8 weeks. Changes after intervention were examined twice after 4 weeks and 8 weeks for degree of obesity and once after 8 weeks only for eating behavior, depression and self esteem. The results were as follows ; 1. Degree of obesity was significantly decreased after 4 weeks and 8 weeks in 3 groups. Degree of obesity after 4 weeks and 8 weeks were not significantly different among 3 groups. 2. The mean score of eating behavior related to obesity decresed significantly after intervention in the behavior modification group only. There was significant difference in eating behavior among 3 groups after intervention. 3. The behavior modification group showed no significant changes in depression and self esteem after intervention. In the aerobic exercise group and group who participated in both behavior modification and aerobic exercise, the level of depression decreased significantly and the level of self esteem increased significantly. There were no significant differences in the level of depression and self esteem among 3 groups after intervention. These findings indicate that behavior modification might be effective in decreasing degree of obesity and eating behavior related to obesity, aerobic exercise be effective in decreasing degree of obesity and the level of depression, and also in increasing the level of self esteem.
