The main purposes of the nutrition and clinical surveys were to provide baseline information on the nutritional status of pre-school children in rural health demonstration project areas of the Korea Health Development Institute (KHDI) for nutrition guidance services for the MCH target group. The survey covered a total of 222 pre-school children and 135 mothers in Okgu Gun, Cholla Pukto Province from August 10 to August 17, 1979. The survey results are summarized as follows: 1) Family Environment Seventy percent of the households had more than three children, and the mean family sire was 6. Sixty-nine percent of the mothers and 47% of the fathers of the surveyed households were educated at or below the primary school level. The majority, 70% of the mothers, were aged between 20 years and 35 years. 2) Anthropometric Measurements and Hemoglobin Value 4.5% of the children were lower than 80% weight for age of the Korean standard, and 5.4% were lower than 85% arm circumference for age of the Jelliffe's standard resectively, and those were suffering from protein-energy malnutrition. Angular stomatitis were observed on 66.2% of the subjects. Mean hemoglobin value was 11.1g/100m1, and 44.2% of the subjects were categorized as anaemia. 3) Food and Nutrient Intake of animal foods was very low, ranging from 2.9 to 17%. Consumption of eggs was less than 2% of total food intake, and intake of legumes was also very scanty, between 0.8 to 3.7%. These data present evidence of very poor protein intake, quality as well as quantity. Energy intake of children was 60.0 to 64.4% of the recommended allowance, and mean protein intake only met 47.4% of the recommendation. Low intake of vitamins except thiamin were also found. 4) Mother's Nutrition Knowledge Eighty-five percent of the mothers were entirely ignorant regarding the 'five basic food group' which is most important fact on food and nutrition guidance. Mean knowledge score from 14 basic questions about food and nutrition was as low as 5.1. There was a significant positive correlation between mother's educational level and nutrition knowledge score. 5) Family Planning Variable There were significant correlation among maternal, family planning variables, and some of the nutritional and physical measurements. The study revealed that the mother's educational level and nutrition knowledge score are more crucial factors than the family planning variables on effecting food intakes on children. Recommendation : According to the results of the surveys, there were high incident rates of nutritional anaemia and angular stomatitis among pre-school children, and most of rural women had very limited knowledge about food and nutrition. As a main part of the health education activities, the community health workers should provide nutrition education to the village mothers to improve the nutrional status of young children in rural areas. Nutrional promotion at the primary health care level should be mainly based on appropriate nutrition education.
The aim of this study is to suggest a new website measurement scale revised in accordance with the present tendency, and to test the practical use of it. The empirically current studies suggest the information, connectivity, practical function, lay - out, design, interlace, system, service as a website measurement scale. However. this study suggest a new website measurement scale including communication between internet users, platform for editing information. The test of a practical use about measurement scale progressed by a survey on computer access. A sample of 300 internet users answered the question based on a new website measurement scale. The result of this study shows that primary factors of the website measurement scale are information, user interface, website service, and communication. The influence of these factors on user's website preference changed as compared with the past. The result also shows that there is close correlation between information factor and communication factor. And the communication factor suggested on this study has effected in user's website satisfaction. Results imply that the idea of web2.0 is practically an important strategy for improving website satisfaction. And, because influence of primary factors on the website satisfaction has changed continually, strategic planning will have to be kept up.
Purpose : With increasing number of school accidents, it is crucial to find out necessity of first aid training among school health educator. This study has been conducted to have an clear idea on the demands and necessity for first aid training and what kind of training is most required from school health educator. Method : In this study, questionnaires from 87 school health educator in elementary, middle and high school health educator in the city D were analyzed. The survey was carned out from May 26, 2008 to June 7, 2008 and from the collected data, frequency, independent two samples t-test, paired T-test, one way ANOVA and pearson's correlation were conducted with SPSS 14.0. Result: 1. 51.61 % of nurse-teachers experienced emergency situations and the relations between the necessity they felt from experiencing those situations and demands for first aid training were not statistically meaningful(t=1.87, p= .175). 2. Necessity and demands for the first-aid training were checked with three point scale and there were statistical significance between the two with $2.44{\pm}.47$ and $2.24{\pm}.47$ respectively(t=3.275, p= .000). 3. 86.20%(75 persons) of the respondents have had received first aid training and the training they received were CPR 82.75%(72 persons), primary survey 81.60%(7l persons), contact to 911 79.30%(69 persons) and wounds treatment(lacerated wounds, bum and chilblains) 75.86%( 66 persons) in order. 4. As for the questions that ask on confidence of first-aid treatment, 80% answered they are confident on some limited kinds of treatments, 16% said they are confident and 4% answered they lack confidence. As for the treatment that they can show the highest confidence, wounds treatment topped the list with 93.24%, nose bleeding and removing foreign substance, and stanching followed the list with 82.43% and 81.08% respectively. 5. 97.67% of respondents said they were willing to take training and 89.62% answered to take the training to deal with emergency situations that are taking place in their schools. As for the question that asks for the most wanted treatments, CPR topped the list with 32.18%(28 persons) and treatment for obstruction of airway and shock followed the list with 35.63%(31 persons) and 27.59%(24 persons). Conclusion : Currently, first aid treatment has been centered on CPR, primary survey, contact to 119 and wounds treatment. However, since most of school health educator are fairly confident with wounds treatment, stanching and other first aids, in future training it will be more desirable to focus on CPR and treatment for obstruction of airway and shock that were shown to be most wanted by school health educator.
Various geological thematic maps have been generated by interpolating sparsely sampled ground survey data and geostatistical kriging that can consider spatial correlation between neighboring data has widely been used. This paper applies multi-variate geostatistical algorithms to integrate secondary information with sparsely sampled ground survey data for geological thematic mapping. Simple kriging with local means and kriging with an external drift are applied among several multi-variate geostatistical algorithms. Two case studies for spatial mapping of groundwater level and grain size have been carried out to illustrate the effectiveness of multi-variate geostatistical algorithms. A digital elevation model and IKONOS remote sensing imagery were used as secondary information in two case studies. Two multi-variate geostatistical algorithms, which can account for both spatial correlation of neighboring data and secondary data, showed smaller prediction errors and more local variations than those of ordinary kriging and linear regression. The benefit of applying the multi-variate geostatistical algorithms, however, depends on sampling density, magnitudes of correlation between primary and secondary data, and spatial correlation of primary data. As a result, the experiment for spatial mapping of grain size in which the effects of those factors were dominant showed that the effect of using the secondary data was relatively small than the experiment for spatial mapping of groundwater level.

In this technical report, we have examined the basic building blocks of mobile ad-hoc networks. The paper discusses various security requirements of ad-hoc networks, attacks in ad-hoc networks, Security Implementation and Routing Protocols. The primary purpose of the paper is to address the Optimized Link State Routing (OLSR) protocol in detail, along with the various possible attacks. Finally, algorithms for securing OLSR are proposed, via the addition of digital signatures, as well as more advanced techniques such as cross checking of advertised routing control data with the node's geographical position. The main aim of this research work is the addition of security features to the existing OLSR protocol. In order to effectively design a secure routing protocol, we present a detailed literature survey of existing protocols, along with the various attacks. Based on the information gathered from the literature survey, a secure routing protocol for OLSR is proposed. The proposed secure routing protocol involves the addition of a digital signature as well as more advanced techniques such as the reuse of previous topology information to validate the actual link state. Thus, the main objective of this work is to provide secure routing and secure data transmission.
Recently, in Korea, single- or two-person households (50.5%) are becoming the primary family type due to increasing divorce rates, population aging, personal code of values and so on. Hence, small families will lead to a sudden increase of single- or two-person households. People searching for small houses are increasing because of the provision of officetels, one room and urban-life housing as well as economic recession. However, this has led to habitability problems, such as parking, storage space and decline in safety. In this study, we obtain the proper contents from LQI indicators of advanced research and use the indicators to evaluate the residential environment quality. We conduct a post-occupancy-evaluation (POE) survey and compare the habitability satisfaction level of apartment and officetel residents. According to the survey, officetel residents' satisfaction levels are low for the following factors in the order listed: ventilation, storage space, management expenses and facilities for children and the elderly.

Pasture in woodland have been extensively established to meet the demand of forage for livestock. The survey type of study was conducted to investigate and analyze for the establishment of pasture in woodland from foresters' standpoint. The findings can be provided for basic data to achieve appropriate wooldland use pattern. The study area was confined to Pyungchang county, Hoengsung county, and Hongcheoa county, which are primary pasturing region in Kangweon province. The analysis was based on the field survey of 30 pastures (grouped to 'successful', 'failed', and 'grazing-in-the-wood' site) and returned 133 questionnaires from 398 debriefed pasture owners.
The beam patterns of source array and changes in the far-field signatures are compared and analyzed each other in order to identify the seismic capability affected by the misfired source at the multi-channel seismic source array. In the primary pulse amplitude of far-field signature, the 66% of seismic capacity are sustained if approximately 40% of source are misfired among whole gun volume. When the sources with the same distances are misfired at the 154㎐, the beam width of the long- and wide-array which is identical regardless of arraying pattern. The beam width has a tendency to narrow now from 41 to 34 according to increase the volume of misfired source at the long-array beam pattern. Therefore, the source array of small volume are suitable for the shallow seismic survey because of producing adequate beam patterns with narrow beam width.
