This pilot study was performed to produce data of the Children's Dietary Life Safety (CDLS) Index which is required by the Special Act on Safety Management of Children's Dietary Life and to evaluate the CDLS Index for 7 metropolitan cities and 9 provinces in Korea. To calculate the CDLS Index score, data regarding the evaluation indicators in the children's food safety domain and children's nutrition safety domain were collected from the local governments in 2009. For data regarding the indicators in the children's perception & practice domain, a survey was conducted on 2,400 5th grade children selected by stratified sampling in 16 local areas. Relative scores of indicators in each domain were calculated using the data provided by local governments and the survey, the weights are applied on relative scores, and then the CDLS Index scores of local governments were produced by adding scores of the 3 domains. The national average scores of the food safety domain, the nutrition safety domain and the perception and practice domain were 23.74 (14.67-26.50 on a 40-point scale), 16.65 (12.25-19.60 on a 40-point scale), and 14.88 (14.16-15.30 on a 20-point scale), respectively. The national average score of the CDLS Index which was produced by adding the scores of the three domains was 55.27 ranging 46.44-58.94 among local governments. The CDLS Index scores produced in this study may provide the motivation for comparing relative accomplishment and for actively achieving the goals through establishment of the target value by local governments. Also, it can be used as useful data for the establishment and improvement of children's dietary life safety policy at the national level.

This survey was carried out for two years from June of 1982 to May of 1984 to investigate factors influencing the Korean native goat rearing. The results were summarized as follows. 1. The daily gain of female goats from weaning age to yearling was 41.9g in average. The maximum and minimum gains were 55.1 and 30.1g, respectively. 2. The mean body weights when purchased from the market were 8.07kg for survived goats and 5.89kg for dead goats. 3. The kidding months of does were distributed throughout all the seasons, and the average litter sizes were 1.2 kids for first kidding and 2.0 kids for second kidding. 4. The amount of DM intake was 2.78% of the body weight. The DM digestibility was 62.91 % for the first pregnant goats under good feeding condition. 5. The amount of DM intake was 3.92% of the body weight. The DM digestibility was 47.01% for the growing female goats under fair feeding condition. 6. The goats seemed to prefer shrub plants to grass. About 65% of the total dry forage consumed was tumbergiana (kudzu).

Most of college women are interested in their appearances, and those whose body weights are normal or even underweight try to lose weight. Many methods for weight control diets practiced by college women are unsound and irrational so that some side-effects should be watched out. The present study was aimed to investigate methods of diets, food habits, behaviors, and side effects of weight control and to suggest sound weight loss schemes for college women. The subjects were 353 college women living in Taegu and Kyung Buk area, comprising 178 women who have tried weight control diets and 175 women who have not tried diets. The items included in questionnaires were food habits, food behavoirs, food frequency, physical activity status, 24-hour daily activity record, height, weight, etc., and the survey was conducted in September 1997. There was no difference in body mass index between college women who have tried diets(20.1$\pm$2.26) and women who have not tried diets(19.3$\pm$1.58), and 24.2% of those who have tried diets had body mass index under 19. The leading reason for diets was to make better fitting for costumes(67%). While women who have tried diets also tried to exercise more, they tended to overeat than women who have not tried diets. Mean of food habit scores(9.33 vs 9.32) which corresponded to "poor" habit and food frequencies were not different with or without experiences of diets. This indicated that diets were not related to actual changes of food habits and food intakes. Diet methods used frequently by college women were relying on special diet foods(25.4%), fasting(24.9%) and exercise(22.6%). Trying both exercise and diet was practiced by only 5.1% of the subjects who have tried diets. The duration time of diets was mostly in the range of 1 week to 1 month, and the longer diet period was, the more weight loss was. The frequent side effects due to diets were anemia(41.8%) and enervation(23.7%). Activity coefficients were lower in those who have tried diets(1.38$\pm$0.13) than those who have not tried diets(1.41$\pm$0.19). Women who have tried diets spent more time on reading newspapers and magazines and on watching TV. This study indicates that college women who have tried diets practiced irrational diets for weight reduction and experienced undesirable side-effects. Therefore scientific and systematic weight reduction programs accompanying balanced diets and proper exercise with behavior changes should be developed.

Health Impact Assessment (HIA) in Korea is conducted for specific development projects within Environmental Impact Assessment (EIA) system. However, as HIA is being carried out in the implementation stage of the development project, it sometimes has failed to take proper actions despite the significant adverse health impact. Considering an environment conflict regarding adverse health impact in developing industrial complex and the current application of HIA in EIA system, it is necessary to come up with an adequacy evaluation in the industrial complex development considering health impact. This study proposes an adequacy evaluation method considering health impact for the industrial complex development and embodies the method by applying it to actual cases. Referring to methodologies of US EPA's CalEnviroScreen 3.0 and US ATSDR's Public Health Assessment, this study proposed using indicators divided by community characteristic, background exposure and development burden as an adequacy evaluation method to consider health impact. Five indicators for community characteristic, three indicators for background exposure and seven indicators for development burden were selected through literature survey, and the weights for each indicator were calculated through Analytic Hierarchy Process's survey of experts related to HIA. Through a pilot application in the three government-led industrial complex development projects, the method was further elaborated by clarifying the evaluation data and subdividing the evaluation criteria for each indicator. Adequacy criteria of plan considering health impact could be presented in three ways to be linked to the government's policy stance on the industrial complex development criteria of total score, criteria of total score and community characteristic score, and criteria of total score and community characteristic allowed by development burden.

The survey guideline of forest products statistics suggests a certain type of standard to aggregate production amount of each item such as dry bracken, raw dates, cracked nuts, It does not, however, give any information about transition ratios, which would apply to convert weights of fresh bracken into dry one, or cracked nuts into the non-cracked. This has been one of the main factors which would make the statistics unreliable. The purpose of this study is to examine the aggregation realities and to put forward some proposals to improve forest products statistics with transition ratios. Targets of this study are 10 forest products that are strongly related to the mentioned problems. With the calculated transition ratios and some assumptions the changing rate of the official statistics of 2004 production amounts ranged from -41% to 474% for the 10 subjects. The suggested figures for transitions are based only on one-year analysis results. Therefore more periods are required to improve the accuracy and the reliability, and this study would be a good starting point.

The purpose of this study is to investigate the directions of information and communication technology(ICT) education in K-12 based on the analysis of ICT accessibility and utilization levels of Korean students. To this end, we analyzed the trends of Korea and OECD countries by survey period, focusing on the OECD PISA 'ICT familiarity survey' conducted in 2009, 2012 and 2015. The surveyed subjects were 15 year-old students and the analysis method was calculated based on the sampling weights. The results of the analysis of Korean students are as follows: First, ICT accessibility at home increased from 2009 to 2015, but was consistently lower than the OECD average. Second, the overall Internet usage time was lower than the OECD average. The Internet usage time on weekdays increased from 2012 to 2015, but on weekends decreased. Third, the ICT accessibility in schools decreased from 2009 to 2012, and increased in 2015, but was lower than the OECD average in 2015. Fourth, the student age ratio of first time computer usage increased from 2012 to 2015 and the average age for computer usage began before age 6, but was below the OECD average. Lastly, student use of digital devices for items such as Internet searches for entertainment and SNS activity has increased from 2012 to 2015, but the level of everyday use such as e-mail, online chat, program downloading, and reading Internet news has decreased. Based on these results, this study suggested policy plans for the improvement of ICT education for elementary and secondary school students in Korea.

This survey was carried out to study the food habit and several health indicators of 438 persons (male ; 179, female ; 259) aged over 60 years old living in a middle city, The results obtained were as follows. The food habit of male was better significantly than that of female, the eating frequencies of fruits, eggs, meats and fishes, and legumes of male were higher than those of female. The mean weights and heights of both male and female were low in comparison to the Korean standard, but the mean BMIs of both male and female showed normal range and the mean obesity rates of male and female were 3.5％ and 8.2％, respectively, The mean hemoglobin content and hematocrit were 13.1g/100m1 and 39.8% in male, and 12.4g/100m1 and 37.8％ in female, respectively, The anemia rate judged by the WHO level of hemoglobin content was 42.0% in male and 34.7％ in female. The mean systolic and diastolic blood pressures of both male and female showed normal range; But the incidence of hypertension judged by the WHO level was 15. 6% in male and 16.7% in female. The subjects suffering from diseases were 78.2% in male and 86.7% in female. Common diseases were neuralgia, circulatory system diseases, respiratory system diseases, diabetes mellitus, and athritis. There were positive correlations between the score of food habit and body weight, height, hemoglobin content, and hematocrit. And there was a negative correlation between the food habit score and obesity rate. Systolic and diastolic blood pressures were correlated positively to skinfold thickness and the incidence of suffering from diseased.

The purpose of this study is to elaborate the request for proposal (RFP) for the localization parts development support project of core parts carried out by the Defense Agency for Technology and Quality. The RFP is the most important document throughout the localization parts project, including project announcement and developer selection, design and test of the development product, final evaluation, and standardization of the project. However, if the RFP is not established at the beginning of the project, there is an increased risk of business failure due to frequent changes by various reasons. In this study, we recognized the necessity of elaboration of RFP and applied the AHP method for quantitative elaboration. Eight requirements of the RFP related to the mechanical/electrical performance of localized development products and three elaboration methods for each requirement were designed in a hierarchical structure, and each weight was calculated by applying the 5-point scale AHP method. The AHP survey was conducted with 20 developers participating in the localization parts project, and the consistency ratio of the AHP survey result was less than 0.1. The elaboration method with the highest value among the calculated weights is classified, and the analysis results and future research directions of the elaboration method are presented.
