The purpose of this study is to evaluate the creation techniques of artificial wetland, one of biotopes developed to promote biodiversity in urban areas, and to look for improvement steps. Specifically, artificial wetland creation techniques were categorized into living environment and living creature classification. Being living conditions for creations, habitat environment was reviewed with a focus on water and soil environments. Living creatures were classified into plants, insects, fish, and birds. The evaluation of creation techniques was done in post-construction evaluation while considering the creation of habitats for living creatures. Intervention by users, changes in living environment and living species, and relevance of creation techniques were reviewed. Key results of this study are as follows. (1) Water environment for the living environment of creatures provides a suitable environment conditions for the living of creatures through a process easing the use of piped water. Various water depths and embankment appear to have a positive impact on the living of aquatic life. In particular, embankment covered in soil naturally played an important role as a place for the activities of aquatic insects and young fish as well as the growth of aquatic plants. (2) Various aquatic and ground plants to promote insect-diversity, shallow water, and old-tree logs had contributed greatly in increasing the types and number of insects. Aquatic insects. Aquatic insects were seen much particularly in areas where aquatic plants are rich but water is shallow than any other areas. (3) A space piled with stone to provide habitats for fish was not much used. However, it was observed that fish used embankment built with natural stones and embankment using logs in areas where water is deep. In addition, it was confirmed that 1,500 fish that had been released propagated using various depths and places for birth. (4) It was analyzed that techniques (creation of island, log setting, and creation of man-made bird nests) to provide habitats and to attract birds are not serving their roles. In such a case, it is believed that species had not increased due to the smallness as well as isolated features of the area. Based on theoretical review, they are judged to be areas that are likely to be used when a greater variety of birds is introduced. It is judged that attracting and keeping more birds at the site, such spaces need to be linked systematically in the future in terms of building eco-network while ensuring an adequate living areas. (5) In the study areas, users intervened greatly. As a result, a blockage was created preventing the normal growth of plants and non-indigenous plants were introduced. In order to limit the intervention by users, setting enough buffer zones, and environment education programs were urgently required. D/H=1>Hyangkyo> houses on the river>temples>lecture halls. D/H ratio of the backside areas is as follows. D/H=1>Hyangkyo>houses on the river>lecture halls. 4. Inner garden were planted deciduous than evergreen trees with Lagerstroemia indica. Enclosed dominant trees were planted by Pinus densiflora, Querces seuata. construct GEM strain, and examined for the expression and functional stability in microcosms.

The aim of the present study was to analyze the elements of young children's leadership which is influenced by socio-demographic variable elements, mother's parental attitude and the ability of children' self-regulation with subjects of 435 five-year-old children and their mothers. Results showed that there was a difference in children's total leadership according to the gender. Regarding differences of mother's rearing attitude, boys showed higher self-control and leadership than girls. In differences of self-regulation and leadership, girls had a higher ability of self-regulation and leadership than boys. For birth order, parents who had more than 2 children show higher Control enemy rearing attitude. Regarding mother's employment, a working mother had freer rearing attitudes. Regarding a mother's educational background, there were differences of groups among rearing attitudes. In differences of family monthly income, there were differences regarding AE static rearing attitudes, autonomous parenting attitudes and get-up-and-go of leadership. Secondly, as a result of the relationship among mother's rearing attitudes had a static correlation between autonomous parenting attitudes and control enemy rearing attitudes. Thirdly, the children's leadership is high when the family income is high, mother's rearing attitude is free and children's ability of self-control is high.

The purpose of this study was to confirm the efficient umbilical cord care of healthy newborns in nursery. In order to determine the efficient care, the time of umbilical cord separation and the skin condition of periumbilical area were evaluated. The data were collected in sample of 529 normal, healthy newborns of C hospital in Seoul, from September 1st, 1999 to January 16th, 2000. The babies were randomly selected and allocated into four groups-alcohol swab/tub bath, alcohol swab/partial bath, natural dry/tub bath, natural dry/partial bath- by the methods of care. The mothers of babies were also surveyed by questionnaire about general characteristics. The data were analyzed by SAS program. The results of this study were as follows : 1. The average gestation period of newborns was 39+3 weeks. The average birth weight was 3.27Kg. In gender of babies, boys were 51.7% and girls were 48.3%. The 65% of newborns were born normal vaginal delivery, 35% were C-section. The feeding methods were 55.3% of the babies fed by mixed type, 22.9% by breast, and 21.8% by bottle. There was no significance among four groups by general characteristics. 2. The average time of umbilical cord separation was 8.27 days(SD=2.3). The time was no difference significantly among four groups(F=1.68, P=0.17). 3. The prevalence of the umbilical care complication did not show differences among four groups( 2=3.93, P=0.27). In conclusion, Nurses have preferred the traditional alcohol swab/partial bath method in care of newborns. But there was no difference among the ways to take care of umbilicus according to this study. The way to naturally is more efficient due to reduce the time and expense in umbilical care for normal babies of nursery. This also matched the change in approach to healthy population from intervention to nonintervention way. This could be suggested in education for normal and healthy babies care at home and nursery as a useful way. Endly, the further study about bacterial colony nda infection rate at umbilicus by ways of care is needed.

Objectives: Children are more susceptible to heavy metal toxicity than adults. The purpose of this study was to evaluate heavy metal concentrations in the blood of Korean preschoolers and investigate the association between metals in blood and related factors. Methods: A total of 512 subjects from 36 to 83 months of age were sampled. A questionnaire survey was performed and the levels of lead, mercury and cadmium were measured in the blood samples of all subjects. Their parents were interviewed in order to obtain information on basic characteristics, dietary patterns, socio-economic factors, and indoor/outdoor environment of the preschoolers. Multiple linear regression was used to analyze the association between the above factors and lead, mercury or cadmium concentrations. Results: The geometric mean concentrations of lead, mercury and cadmium in the blood were $1.45{\pm}1.58{\mu}g/dL$, $2.14{\pm}1.74{\mu}g/dL$ and $0.23{\pm}1.91{\mu}g/dL$, respectively. Results from multiple linear regression analysis showed that blood lead levels were associated with birth weight and paternal smoking status. Daily mercury intake from food and maternal education were also shown to influence mercury concentrations in blood. Also, blood cadmium concentrations were associated with maternal age and having a bus garage near the place of residence. Conclusion: This study suggests that smoking status, dietary patterns and the environmental status near the residence should be considered as important factors for preventable sources of heavy metal exposure in preschoolers.

This study was carried out to find the relationship among dietary behavior, dietary self efficacy and nutrition knowledge according to the perceived body shape of the 5th and 6th grade elementary students in Gangwon Province and found out their relationships. The results are as follows; The factors that showed significant difference according to perceived body shape were gender, father's education level, the number of siblings, birth order, obesity of parents and siblings and ideal body shape. For the perceived body shape, the students answered generally normal(48.9%), slightly fat(27.9%), thin(16.5%) and very fat(6.7%). Out of total students 76.5% of them were not satisfied with their body shape such that satisfactory(23.5%), want to lose weight(61.4%) and want to increase weight(15.1%). The score of eating behavior showed significant difference between perceived body shape on such questions as eating speed(p<0.001), frequency of fatty food intake(p<0.001), adequate intake quantity(p<0.001), balanced diet(p<0.05), frequency of going out to eat(p<0.001). The score of diet self efficacy showed significant difference in the area of general habit on such questions as whether to eat slowly together with friends (p<0.001), whether to eat adequate quantity(p<0.001), whether not to have snacks after dinner(p<0.001). And in the area of food selection it showed significant difference on such questions as to select ice cream in stead of yoplait(p<0.001). In the area of social circumstance it showed significant difference on such questions as to reject the food(p<0.01) and to restrain food in birthday party or holiday(p<0.05). In the area of emotional status it showed significant difference on the question about food restrain when boring and depressed(p<0.05 respectively). The score of nutrition knowledge showed significant difference according to the perceived body shape on such questions as total score(p<0.01), five basic food group(p<0.05), snack and body weight(p<0.001), calcium function(p<0.01). It showed perceived body shape co-related with the nutrition knowledge(p<0.01). In summary, the perceived body shape for the highly eating behavior was generally normal, for the highly dietary self efficacy was slightly fat, and for the highly nutrition knowledge was also slightly fat.

The military is an organization where reliability and availability take much more importance than in any other organization. And, in line with a recent trend of putting emphasis on 'system readiness', not only functions but also availability of a weapon system has become one of achievement targets. In this regard, the military keeps spares for important facility and equipment, which is called as Maintenance Float (M/F), in order to enhance reliability and availability in case of an unforeseen event. The military has calculated yearly M/F requirements based on the number of equipment and utilization rate. However, this method of calculation has failed to meet the intended targets of reliability and availability due to lack of consideration on the characteristics of equipment malfunctions and maintenance unit's capability. In this research, we present an analysis model that can be used to determine an optimal M/F inventory level based on queuing and absorbed Markov chain theories. And, we applied the new analysis model to come out with an optimal volume of K-1 tank M/F for the OO division, which serves as counterattack military unit. In our view, this research is valuable because, while using more tractable methodology compared to previous research, we present a new analysis model that can describe decision making process on M/F level more satisfactorily.

This paper analyzes the factors influencing the childbirth intention of married women with the goal of analyzing whether times of spouses' housework, marital satisfaction, values of children and traditional gender role, and social services related to the reduction of low fertility contribute to women's intention to give birth. The respondents of the research were 1,000 married women, and the research was conducted with 482 women of childbirth intention. The findings are as follows. Age of sociodemographic factors has an influence on the childbirth intention. Related to family's character, factors influencing childbirth intention are number of children, times of spouses' housework, and marital satisfaction. In addition, emotional and instrumental values of children, number of recognized public services for reduction of low fertility. In other words, the more women share housework with spouses and satisfy their marital life, the more childbirth intention of women is increased. In order to improve childbirth intention, changes of perception of gender role and sharing housework, reinforcement of social system for work and family compatibility that convert changes of perception into action, advanced marital relationship programs, extensive support for subfertility and a huge build-up of social services related to reduction of low fertility need to be provided.
