This survey was undertaken for the period seven month beginning January 15, 1977 and ending July 31, 1977 to detect the general sanitary status of the villages and the villagers and, at the same time, analyse quality of water sources with emphasis on a total of 1,256 households dividing into three different groups: such as, 280 households were selected as random samples from the area of the sophisticated piped water supply system, 122 households from the area of the simplified water supply system and finally 854 households from the area of nonpi-ped water supply system. The following results were concluded after quality of water sources had been analysed and conditions of the environmental sanitation had been reviewed: 1. 11.2% of the respondents from the area of the sophisticated piped water supply system responded that quantity of drinking water lacked to meet their demand while 30.6% of the villagers from the area of nonpi-ped water supply system responded quantity of drinking water didn't meet their demand. 2. 30.8% of the.respondents from the area of the sophisticated water supply system responded that contaminating source located within 15 meters from the water source while 54.4% of the respondents from the non-piped water supply system claimed the same. 3. It was found that water from all sampling areas were positive in coliform group with exception of Moonsan which is one of the sophisticated piped water supply system groups and the number of general bacteria exceeded the government standard criteria of water quality in the area of the nonpi-ped water supply system. 4. In relation with time requirement to draw water in the area of non-piped water supply system, 76 respondents claimed it requires less than 15 minutes to draw water, 15.0% claimed 15 to 30 minutes and 9.0% claimed more than 30 minutes. 5. In relation with knowledge on sanitation of drinking water, 30.8% of respondents from the area of the sophisticated piped water supply system and 41.8% of respondents from the area of nonpiped water supply system denied possible existence of germ in drinking water they drink, while 17.4% of the respondents from the area of the sophisticated water supply system and 50.2% of non-peped water supply system thought it safe to drink water without any treatment. 6. 60.0% of the respondents from the area of non-piped water supply system and many of them believed that their health status will be improved by installation of a sophisticated water supply system in their area. 7. The respondents from the areas of piped water supply sytem expressed greater concern over drinking water sanitation than those from the areas of non-piped water supply system and sanitary conditions were found the same. It was, therefore, proved that knowledge of environmnntal sanitation contributed a great deal to improve sanitary conditions of the villages and villagers and at the same time health education, especially environmental sanitation, will be played a important role to improve their sanitary conditions.

Methods: This study was performed to estimate the use of frozen convenience food in middle schools located in the Daegu district. Objectives: These schools have directly managed school meal services. The subjects for this study were 145 students and 66 dieticians. The study involved a survey on food preference and quantity satisfaction of the students and the frequency of use of frozen convenience food in the daily menu. Results: As the result, 50.0% of the students were not satisfied with the meat and poultry quantity from school meals(felt small), and 25.0% of students were not satisfied with vegetables(felt much). The majority of students (50.7%) who were not satisfied with vegetables said they were dissatisfied with the school food because of the taste. On the other hand, 36.6% said they were dissatisfied because they dislike vegetables in general. As for the use and frequency rate of frozen convenience food, the survey results were revealed in the order of dumpling 58.3% > processed meat 50.0% > chicken 50.0% > frozen marine food 40.4% > cuttlefish 30.3% > miscellaneous 26.3% > vegetable & potatoes 14.4%. It was found that many schools employing more than five workers did not use flour-based frozen foods in their menu. As for the use of the frozen processed food, many schools which had an average food cost of more than 1,700 Won were found to use frozen foods more than once a month. In addition, chicken was not used often at the schools whose average food cost was less than 1,500 Won while many schools, whose average food items cost was more than 1,500 Won, incorporated chicken into the menu once a month. Processed flour food [hot dog] was used often by schools whose average food cost was between 1,500 Won and 1,600 Won. As for the actual conditions of using frozen convenience food, there was a significant difference in the use of chicken in relation with the number of food service recipients. As a result, the use of frozen convenience food has been shown to be related with food cost, number of food preparers, and the number of school students.

The purpose of this study is to find the reality of environmental management cost in construction projects and to suggest some policies in order that owners appropriate the environmental management cost reasonably in the construction budget for reducing the environmental pollution at job sites. We surveyed the actual state of appropriating and expending the environmental management cost over 122 construction sites. According to the results of the survey, while the appropriated rate of the environmental management cost was 0.59% of the total construction cost. the expended rate reached at 0.94%. When examining the antipollution facilities which were operated in job sites, the investment for equipment against air-pollution such as tire washer, dust-proof device was relatively higher than other antipollution equipment. As the method appropriating the environmental management cost, we concluded that a quantity-per-unit costing method is more reasonable than appropriating at a fixed rate of total construction cost considering that there is little correlation between total construction cost and the environmental management cost. To do so, antipollution facilities that must be examined at a design or estimation stage of a construction project should be prescribed by the law. Moreover, referenced cost data for the quantity-per-unit costing should be prepared and officially published.

Cost Estimating allows each entity in a construction project to plan, distribute, and control its required construction cost for the project. However, existing 2D design based estimating has problems, such as inaccuracy and inefficiency caused by missing, duplicated, or erroneous calculations. In this situation, current estimations for school facilities have more difficulties in forecasting construction costs due to an inadequate work breakdown structure for BOQ (Bill of Quantity) and insufficient guidelines for Basis of Estimate. In this study, therefore, an effort was made to increase the efficiency of estimating for school facilities by applying a 3D modeling based BIM tool to quantity and cost estimates. In addition, this study suggested a reasonable work breakdown structure for BOQ that was appropriate when 3D modeling was applied, and verified it through a case study. The authors tried to provide a BIM-based estimating method for school facilities to obtain greater accuracy and efficiency by having more information in an earlier stage.

The purposes of this study are to evaluate the utilization characteristics of electrical power consumption, to grasp the present trends in the use of electrical equipments, to estimate the demand factor and load factor being held, and to evaluate the efficiency of electical uses for the recently electrified farms cultivating paddy rice. For the purposes, 109 sample farms located in eleven villiages electrified in six different years from 1968 to 1973, were chosen at random and investigated on 35 items concerning to electrical uses and wiring systems. The survey was carried out in 1975, in the vinicity of Suweon city. The results are summarized as follows: i) The average annual power consumption on sample farms is considered to be low, being 242.9 Kwh. in 1974, and varied according to the different electrified year and size of cultivated land, respectively. It has significant positive correlation to the area of farm, too. ii) Between the number of year of electrical uses and the power consumption, there is very significant positive correlation, which could be expressed as Y=43.041+16.108 X, where X represents the number of years of electrical uses. The annual increment of power consumption is much greater at the beginning of the electrification than that at the later years, its average being approximately 20 percent. However, it is recommended that any estimation of long-term increments should be carefully investigated. iii) The monthly power consumption varies considerably throughout a year, in which the heaviest farm load occurs in November. Observing the seasonal variation of consumption, the winter-time is the heaviest season while the summer is the lowest. The result implies house lighting is chief contribution to the present electrical consumption on the farms. Comparing the variation of monthly consumption ratios between the sample farms and industries, the electrical uses on the farms are independant of the industrial uses, and further, the agricultural uses are of inverse pattern to the farms from the results that there is negative correlationship between them, iv) The number of electrical equipments used on the farms are occupied chiefly by lighting sources. Next to the lighting sources, household appliances of small quantity and some motors are used. The mean electrical quantity is about 1, 127.4 watt, which corresponds to about 37.6 per cent to the contracted quantity. The composition of quantity is chiefly occupied by the electrical motor of about 1.5 hp., single-phased. The number of the annual utilization hours of each equipment is tabulated in Table IV-5. In contradiction to the high utilization of lighting sources and small household appliances, the motor is poorly used for approximately 22 hours in a year. v) More than 55 per cent of farms want to purchase new electrical equipments such as small household appliances and electrical motors in their number. The impulse of purchasing such items is stimulated by the contacts to the mass media and their knowledge on such equipments. Consequently, the increase of electrical uses could be prompted by such trials as education and demonstration. vi) The demand and load factors on the farms vary considerably according to the greater variation of the power consumption, daily or monthly. The daily demand factor is 22.4 per cent and load factor 18.6 per cent, while the annual demand factor is 1.3 per cent and load factor 70 per cent approximately. Therefore, the low efficiency of construction cost requires re-evaluation of the present contracted quantity of 3 Kw. or increase of electrical uses. vii) The electrical energy on the farms devoted chiefly to lighten the farm residences does not contribute to the farm incomes. Consequently, the cost of electrical consumption presses considerably upon the farm economy. Therefore, there is great need to build up the electrical uses on the farms through the development of new works and techinques to utilize any electrical equipments on the production of farm products. Further more, such the development should be related to increase the actual income of the farm consumers.

For the diversity of energy supply system and the improvement in the habitants' living environments of the islands, it is possible and necessary to use the natural energy as resources of the electric power generation system. In this study, the characteristics of wind and solar radiation on 4 islands offshore Namhae-Tongyoung of Korea were measured for one year from November 2010 to October 2011 and analyzed in relation to energy resources survey. As a result of measurement and analysis, the respective wind rose diagrams of 4 islands were made, and showed that the frequencies of wind directions were quite different from among the islands. The Rayleigh probability distribution of wind velocity showed that the wind speeds of KR and SS were mainly 2~5m/s, and the respective quantities of electric power generation of 4 islands were shown to be different. The variation of solar radiations and potential quantity of those uses were measured to be similar to each other among 4 islands.

This study was conducted to illustrate standard menu items available in the school foodservice industry, and to establish higher nutritional standards in this industry. We reviewed menu items from 125 middle and high schools from the Seoul area for three months. These menus were then classified into 12 representative menu items, as follows: beef seeweed soup, egg soup, sliced rice rod soup, spaghetti, sauted squid with hot sauce, fish cutlet, simmered pork-egg in soy sauce, sweet and sour meat, sauted pork, acorn starch jelly salad, cucumber salad. And standard recipes of these 12 representative menu items were established, based on a survey from 150 dietitians who completed a questionnaire of 97 questions. According to the survey results, 89% of the dietitians answered positively('yes') about the necessity of establishing standard recipes for the school foodservice industry. 69% of the dietitians were educated standard recipes for the school foodservice, 91% will use standard recipes for the school foodservice Moreover, we discovered there was a consensus on what type of menu items should be included on the menus; demographic factors only affected a small range of recommended items. In order to confirm real application of resulted standard recipe, it is required to conduct quantity food production at real foodservice and study on more suitable standard recipe.

In order to find smoking status and its related factors for female students, a survey was conducted for 1,045 female students of a women's university in Seoul from 22nd of May to 18th of June, 1995. The results were as follows: 1. Of the 1,045 respondents, 7.4% of them were current smokers and 20.6% of them were ex-smokers. The rate of smoking by the major field of study was 18.5% in art and physical education, 10.6% in liberal art and social science, 1.9% in natural science, and 1.2% in medical science. The rate of smoking by the grade was 4.1% in the freshman, 5.9% in the sophomore, 10.9% in the junior, and 10.0% in the senior grade. 2. 7.2% of respondents experienced first smoking at junior high school, 16.8% at senior high school, 4.1% after high school, and 69.2% at college. 3. The major motivation to start smoking was 'curiosity'(57.9%), 'releasing stress'(21.6%), and 'temptation from friend or senior'(12.0%). 4. The first smoking place was 'entertainment place'(49.6%), 'own room'(20.5%), and 'school '(11.3%). And the first smoking companion was 'friend'(62.3%), 'alone'(19.9%), and 'senior or junior'(5.1%). 5. The average quantity of a daily smoking was 6.16±5.29 cigarettes in current smokers and 31.2% of them had experience to quit smoking at least one or more time. 6. Most of the reasons to quit smoking in ex-smoker were due to 'bad taste '(60.5%), 'health concern'(27.4%) and 'religion'(2.3%). 7. Current smoker and ex-smoker had more positive attitude for the female smoking than nonsmoker. And 76.7% of nonsmokers answered that they would not smoke in the future. 8. Most correspondents(89.8% of nonsmoker, 83.7% of ex-smoker, 80.5% of current smoker) strongly supported the antismoking movement. 9. The major information source in smoking were from 'radio, TV'(51.0%), 'newspaper, magazine'(38.8%) and 'school'(7.7%). 10. The multiple logistic regression analysis showed that the related factors for smoking status were satisfaction of home life, coffee intake, alcohol drinking, sister's smoking, girl friend's smoking, and knowledge about smoking.

Nowadays, public rental apartments' community facilities emphasize only their quantity aspect without considering residents' characteristics, leading their installation regulations to be based on only the number of households, which is problematic. As a result, in many cases, residents, after moving in, alter the facility usage or remodel the facilities for their use. Hereby, this study conducted focus group interviews with public rental apartments' residents as to find out space conditions of and improvement demands for the community facilities. Two public rental apartment complexes in Seoul and Gyeongi-do which were built after 2007 were selected for this study. As for the survey method, workshop panel was employed. Four people in each age class of infants, children, adolescents, adults, and seniors were formed into one group, and a total of 40 people in 10 groups were surveyed. The survey was continuously conducted from February to March in 2009. The study findings can be summarized as follows. 1) Among community facilities, there were more satisfactory outdoor facilities than satisfactory indoor facilities. Residents expressed satisfaction with the facilities linked with natural environment. The causes of unsatisfactory facilities were mostly poor management. 2) The facilities demanded by the residents included ones relevant to study, exercise, and hobbies. As public rental apartments are resided mostly by low-income families, study and hobby activities bring them cost problems. Therefore, it is needed that the apartment complexes support diverse such activities 3) As for facilities demanded for usage alteration, a residents' meeting room accounted for the most popular opinions. As it was used only once a week, its usage was very low. It should be opened to the residents and allowed to be used in various ways. 4) As for demands of changing spatial characteristics, outdoor exercise facilities accounted for the most opinions. Although they were installed in most cases, they were damaged and poorly managed, therefore being in need of improvement in operation and management. In order to maximally utilize public rental apartments' community facilities, facility planning in consideration of various age groups from residents' viewpoint and sustainable systematic management are required.
