For this study, 2,712 sheets of the chest x-ray films of neonatuses, infants and early children were observed statistically and then the following results were obtained: 1. Seasonal increment of patients was overwhelming in spring and summer in compare with in autumn and winter. 2. Males was majority in distribution by sex. Neonatal and infancy group was the largest in number by forming 29.46% in distribution by age group and then follows six-years group(14.75%), one-year group(13.64%) and five-years group(12.61%) 3. In radiographical projection for chest, a great proportion was P-A projection as 53.72%. But, almost all the neonatal and infancy group and emergency patients were by A-P projection 4. As for x-ray findings, 78.47% was normality while 21.53% was abnormality. Tuberculosis(176 cases), was the largest in number in abnormal cases and next in rank was pneumonia(128 cases)and then congenital heart disease(82 cases). 5. Adequacy of exposure was disclosed as follows: 57.01% in correct-exposure 29.20% in over-exposure, 13.79% in under-exposure. 6. The x-ray beam was not restricted in 77.10% of total films. 7. "Good" formed 30.01% in position immobilizing of the patient and "ordinary" formed 38.02%, "bad" 31.97%. Especially, "Bad" formed high percentage in neonatal and infancy group.

This is a study to analyze rural area women's perception and practice of prenatal care, which is the fundamental of the education of children. Further, it was aimed to provide basic data for ideal childbirth, upbringing and household management process. For that object, questionnaires were distributed to women living in Yongdong region to judge the level of general understanding on prenatal care. Research was done from three different aspects; dietary life, emotion control and health management. Percentages were drawn out to see the general tendency. The following results were discovered from data analysis: 1. Most subjects of the survey knew well about prenatal care. They had acquired that knowledge from their parents. Most thought that prenatal care is necessary. They answered that they think prenatal care has more or less effect on the fetus. The first dime they thought about prenatal care was after they found that they were pregnant. 2. The subjects knew well about dietary needs for pregnant women carried out much of what they knew. Intake of sufficiently nutritious food is somewhat difficult, but foods that are regarded as bad were avoided thoroughly. It appears that most women have much concern about what they eat during pregnancy. 3. Most of the subjects understood that the emotional stability is necessary but it wasn't put into practice so well as in dietary life. Especially, attitudes connected with emotional development like, "Look or hear only what is good (for the fetus)" were practised little. Efforts for self-restraint as "Not to hate or pick out others' defects or talk bad about others" were appeared to be great, and it is practised well, too. 4. The subjects were well-informed on health area, but practised little. Behaviors for health improvement as to "Lead a regular daily life for health" or "Not to take a long trop" were practised very faithfully. The results of the survey showed that passive attitudes related to tabooed food, self-abstinence and cautions for bodily safety were prevalent; more positive and progressive disposition missing. That is, full perception and active practices for caloric intake, emotional improvement and physical strength development are needed.

Most of the guided weapons have been kept and transferred at the launching tube and fired in case of necessity in these day. Launching tube is a kind of case to protect the guided weapons from external environments and conducted as a guide when they are fired. When we attached the guided weapons to launching tube we usually has used explosive bolt. Explosive bolts have been used explosives when they had to be separated. But when they are separated there are some bad effects; a flame, fragments and pyre-shock. Because of these bad effects there are many restriction to use bolt as joining devices to precision guided weapons. To solve these problems we invented ball type bolt. Unlike explosive bolt, ball type bolt is separated without a flame, fragments and pyre-shock. And it also has a good mechanical properties as much as those of explosive bolt.

This study was conducted to analyze the planting structure and ecological characteristics of greon spaces on the grounds of e Dangjin steam power plant. To achieve these goals, we surveyed existing vegetation, plant community structure, Plant volume and growth rate. Based on e vegetation analysis, existing vegetation was classified into six types: herbaceous species $(70.54\%)$, evergreen coniferous trees $(21.17\%)$, deciduous broad-leaved trees $(5.10\%)$, deciduous coniferous trees $(1.47\%)$, shrubs $(0.12\%)$, and other types $(1.59\%)$. The coal storage, office, and playground areas were community is the natural forest area where a Pinus thunbergii / Pinus densiflora community is distributed in terms of vegetation structure, species diversity, plant volume, and growth rate. The artificial green spaces(near the coal storage, office, playground areas) had a single-layer structure. Species diversity indices of the artificial green areas were $0.1655\~0.4807$ compared to 0.8628 in the natural forest, which presented a good growth environment. Also, the plant volume in the artificial green space was lower than that of the natural green space. Therefore, it would be desirable to develope a multi-layer structure similar to that of the vegetation in the natural green space in order to improve the amount of plant volume. The plant-damage ratio of Pinus thunbergii was $52.48\%$ in the coal storage area, and $8.48\~ 11.52\%$, in the other survey areas. Also, the vitality of Pinus thunbergii was $15.45k{\Omega}$ in the coal storage areas, which indicates bad growing conditions. This suggests that soil characteristics and dust have a bad impact on growth. The investigation into deciduous tres' growth status showed that appropriate plants would be Albizzia julibrissin, Acer palmatum var. sanguineum, Acer palmatum, Malus spp., Prunus sargentii.

The aim of this study was to identify the drinking patterns and needs for nutritional education of male workers. The subjects in this study were 285 male workers in Ulsan City. The average age of the subjects was 41.2 years old, height was 171.8cm, weight was 69.6kg and Body Mass Index(BMI) was $23.6kg/m^2$. The subjects were classified into 3 drinking patterns such as 'normal drinker(ND)', 'excessive drinker(ED)', and 'alcoholic drinker(AD)' diagnosed by NAST (Alcoholism Screening Test of Seoul National Mental Hospital). Each group was 31.6%(ND), 43.2%(ED) and 25.3% (AD). The amount of one time drinking, frequency, kind of alcohol and spending money were significantly different among the groups. 87.8% of ND thought that the self identity of drinking habits was good. But twenty seven percent of AD thought that it was just not bad, one-half of them(51.4%) thought they seemed to have problems and 20.8% of them thought they were serious. 38.9%(AD), 22.8%(ED) and 6.7%(ND) of each group tried to abstain by turn. Reasons of trying to abstain were health problems, disharmony of family and bad influence on the business and job place. The methods of abstaining were to avoid a drinking gathering or to refuse drinking in the party. 70.8% of AD, 59.3% of ED and 40% of ND thought they needed to take an educational program about abstaining. 58.3% of AD, 43.1 % of ED and 31.1 % of ND answered they would join an alcohol program.

The purpose of this study is to investigate the effect of temperature control by a shade tree and the lawn area. In this investigation, we find out that artificial-lawn, concerte, and exposed soil are more higher temperature than covered with plant materials. The results of the measurement may to summerized as follows; 1) Low-temperature effects of zoysia japonica is more controlled by condition of growth than leaf length of grass. Surface temperature make 0.7$^{\circ}C$ difference between long grass (15cm), and short grass (5cm), but make 5$^{\circ}C$ difference between good growth grass (230/10$\textrm{cm}^2$) and bad growth grass (80/10$\textrm{cm}^2$). 2) The surface temperature of the lawn area is 40.5$^{\circ}C$ lower on a maxinum than that of the artificial lawn (July 28, 1985). During the day of summer, shade area under the shade tree is 0.9$^{\circ}C$ lower then lawn area surface temperature, 6.9$^{\circ}C$ lower than bad growth lawn, 10.3$^{\circ}C$ lower than exposed soil, and 18$^{\circ}C$ lower than concrete surface temperature. 3) Natural irrigation effect on the surface temperature fluctuation. But this effect is changed by compositions of ground materials and time-lapse. 4) Sunny day is more effective than cloud day. 5) In summer season, surface temperature make a difference compare to temperature of 0.5-1.5m height from ground : Surface temperature is 3.4$^{\circ}C$ lower at the lawn area (11 a.m.), 4.2$^{\circ}C$ lower at the shade area the shade tree, 12.7$^{\circ}C$ higher at the concrete area (3p.m.), 38.8$^{\circ}C$ higher at the artificial lawn (2p.m.) 6) According to compositions of ground materials and season have specific vertical temperature distribution curve. 7) In summer season, temperature distribution of 0.5-1.5m hight at the shade tree is 4.8-5.7$^{\circ}C$ lower than concrete area (noon-3p.m.)

In this paper, Fengshui Theory Analysis Eunpyeong-New Town. The analysis frame is man and nature integrated, suit one measures to local conditions, analysis of macro environment site selection, analysis of micro environment site selection, analysis of traffic lines, orientations of residential analysis. The result is as follows: The analysis of the macro environment site selection of Eunpyeong-New Town at Northwest Mountain shape is open, so in the winter exposure of the northwest there is wind. Therefore, according to Fengshui there is a bad pattern formation. Analysis of the macro environment site selection has four animal frames seperated into two districts. The result is district one has "bad" ground. District two uses Bibo to restore small brooks so the formation has "good" ground. Finally, we use Fengshui of Bibo to propose solutions.
