The purpose of this study was to investigate the psychosocial factors influencing dairy product consumption of female university students in Daejeon. The Theory of Planned Behavior provided the basis for this study. As a result of the pilot-study, 18 behavioral beliefs, 8 normative beliefs, and 12 control beliefs were identified. The subjects (n=236) were grouped into a high-consumption group (1 serving/day, n=117) and a low consumption group (< 1 serving/day, n=119). The data were analyzed using t-tests or $\chi$$^2$-tests. Among the general characteristics, there were significant differences in the amount of pocket money spent per month, residence type (p<0.01), weight, frequency of exercise and perceived health status (p<0.05) of the subjects. With respect to the 18 behavioral beliefs, the high consumption group responded less negatively on ‘eating dairy foods would not be convenient’ than the low consumption group (p<0.05). None of the subjective normative items were significantly different between the two groups. However, notable differences were found in regard to the control beliefs (8 out of 12 control beliefs). These included overall control over consuming dairy products (p< 0.001), as well as specific beliefs regarding barriers such as easy spoilage of dairy products, the cost, eating them for snacks and dislike for them (p<0.05). In addition, specific situations, such as ‘when I want them I get them’ (p<0.01), eating out and the availability of dairy foods at home (p<0.05) were significantly different between the two groups. The high consumption group showed more control over these barriers or situations. These results suggest that nutritional education for young female adults should incorporate strategies to increase their perceived control over the consumption of dairy products by removing barriers and including environmental approaches which address the availability issues.

Purpose: The aim of this study was to identify the factors related with the intention of smoking abstinence among elementary students in a metropolitan city in Korea. Methods: All the elementary schools in the city were stratified by region, and then schools as a primary sampling units (PSU) were selected by probability proportional to size (PPS) sampling. One class per grade was sampled randomly from 5th and 6th grade in the sampled schools from October to December in 2004. The students completed a standardized self-administered questionnaire anonymously. A total number of 1,712 respondents who did not smoke was included in the final analysis. The dependent variable was an intention of smoking in the future, and it was dichotomized into 'absolutely confident in smoking abstinence' and 'others'. The risk of non-absolute confidence in smoking abstinence was calculated with simple and multiple logistic regression, which were conducted with STATA 9.0 by a design-based analysis considering strata variable, PSU, and sampling weight. Results: In the final model of multiple logistic regression analysis, those who were more likely to have non-absolute confidence in smoking abstinence were male students (OR=2.66, p<0.001); barely attending religious services (OR=3.32, p=0.002) or having no religion (OR=1.95, p=0.027); exposure to environmental tobacco smoke outside home 1${\sim}$2 days per week (OR=1.60, p=0.013); having friends who smoked (OR=1.93, p=0.011); non-absolute confidence in refusing to smoke (OR=5.35, p<0.001); having relatively less negative attitude (OR=2.88, p<0.001), positive attitude (OR=2.35, p<0.001), and indifference (OR=4.05, p=0.034) toward peer smoking; not good relationship with mother (OR=1.52, p=0.016). Conclusion: The factors related with non-absolute confidence in smoking abstinence were coincided with those of smoking among children. The results of this study suggest the smoking prevention education should be applied to the children more actively, especially who are not confident in smoking abstinence in the future.

The effect of physico-electrochemical properties of carbon bipolar plate(BPP) on hydrogen and formic acid fuel cell performance has been investigated. BPP made of conventional graphite and carbon fiber composite were compared with the factors of interfacial contact resistance (ICR), corrosion behaviours, and hydrophobicity. Among them, the ICR of carbon fiber composite BPP has 50% higher than conventional graphite and the surface of carbon fiber composite BPP became rougher due to weaker corrosion resistance. Fuel cell performance was strongly dependent of ICR value of carbon bipolar plate.

This study aims for strengthening the ability of home visiting care giver by figuring out interpersonal stress of bearing hardships which affect turnover intentions of home visiting care givers and by focusing on mediating effect of burnout. First, in summary, the analysis result was that the age of care givers and the presence of spouse are in relational factors correlated with burnout. Also age and experience of turnover have some connection with turnover intentions. Second, interpersonal stress of burnout and turnover intentions have static correlation. Third, the interpersonal stress represents increasing level of stress of burnout and the intervention of burnout shows static effects on turnover intentions of care givers. Suggestions of this study's results are, first, solution of interpersonal stress which home visiting care givers are facing should be improved by families' support or encouragement. In addition, the more professional and organized job training should be advanced to improve the understanding of various situations and coping skills. Second, the more interest should be need on business characteristics and environmental limitation. Also many centers that support care givers should reinforce their role. Third, to decrease the turnover intention which comes from interpersonal stress, doing some burnout research could be helpful and especially the legal regime which supports the research of burnout is essential.

Recently, USN technology has been spreaded to all areas of application systems. In addition to urban application systems such as u-City, u-Home and u-Education, u-Farming(ubiquitous farming) technology supports agricultural innovations in the farm. In the u-farming environment for livestock or plant production, key environmental factors i.e. temperature, humidity and luminosity are to be set optimally to increase productivity and safety by applying USN technology. This approach could change agricultural environment. In this paper, we proposed an implantable micro sensor node to be implanted into laying hen to monitor deep body temperature. This sensor node uses SoC(System-on-Chip) designed for USN. In addition to that, we discussed about further considerations on the practical use of proposed sensor node.

This study was conducted to determine the influence of socio-economic status of potential consumers on the types of senior congregate housing(SCH) among 4 urban areas(Seoul Metropolitan area, Busan, Gwangaju, and Daejun). This study was part or a research series to develop SCH which meets the korean situation. The Questionnaire used for the final analysis involved 1006 people and SPSS Windows program was used for statistical analysis. The opinion about SCH should differ among the 4 urban areas according to Socio-Economic Status(SES). The results of this study were as follows: The opinions on SCH varied in each region according to SES indicating that diverse constructions of senior housing to meet selective needs of the old can create high demand in a construction market. In order to induce active participation of the private sector, the Ministry of Construction and Transportation, rather than the Ministry of Health and Welfare, should be in charge of the development of SCH. This is desirable in the perspective of developing new types of housing as for general housing. In this case, the Ministry of Construction and Transportation should consider geographic locations and environmental factors of each city. Moreover, the successful development of SCH needs an effort to reexamine an appropriate development plan rather than adopting the cases of developed countries without criticism. In terms of policies, the government should provide financial support for building sharing space, give an exception on a measurement rate, assist in the education of supervisors and establish a management system and so on.

The purpose of this study is to measure some physical environmental factors and to doucument students' perceptions of them. 11 middle schools in Cheju City were divided into four areas according to their locations and two schools were selected for the study. 144 thirteen-year-old students in two middle school in a overcrowded area in Cheju City-one middle school building is insulated and the other is not insulated-were taken for the questionnaire survey. The finding of the study are as follows: 1) The classrooms were not equipped with any heating equipment. The buildings are not insulated well. As a result, the room temperature was much lower(12.9-16.2℃) than comfortable indoor temperature in winter(21.5-24.5℃). The classroom were found to be colder(12.9-16.2℃) than usual pleasant indoor temperature(21.5-24.5℃) in winter. 2) The classroom were so far from the street(20m) that there was little noise from traffic. Nevertheless, the noise level was higher(62.5-66.2 dB(A), when the windows were open; 51.7-62.8dB(A), when closed than the noise tolerance level specified in the Environment Protection Laws(50.0dB(A)). 3) As for the visual environment, the location of classroom, the adequate sun exposure, and the total states of windows in classrooms influenced on the illuminance. While standard indoor illuminance is 300 Lux, the classrooms facing south had illuminance of 231 Lux, from day light: and the ones facing west, 380 Lux. 4) Students generally found other aspects of the physical environment of their classrooms unsatisfactory. Chalk dust was generated to a serious extent near the main chalkboard(0.25mg/㎥) of classrooms.

Unintentional injuries are the most important cause of morbidity and mortality in the pediatric population, and the home is the most common site of injury for children in Korea. The most common cause of injury was slip down. Fall down and burn were frequent in infant/toddlers group, automobile and bicycle accident more frequent in preschool children. Findings from the survey could then be used to provide targets for direct educational efforts by medical services and to direct environmental safety modifications tailored to the unique situation of each family. Pediatric toxic ingestions are treated commonly by pediatricians and emergency physicians. Significant injury after these ingestions is infrequent, but identifying the dangerous ingestion is sometimes a difficult task. By performing a detailed history, focused physical examination, and directed laboratory evaluation, an estimation of risk can be developed. According to recent Korean poison papers, there were bimodal peak of age distribution in poisoned children patient on the whole: infant and adolescents group. Various types of materials belonged the classes of drugs, household products, and industrial solvents. Most of the poisoned children patients had been poisoned accidentally, while most cases of adolescents poisoning had been intentional. More than half of the adolescents group had a suicidal purpose in Korea, so an understanding of the demographic factors associated with self-harm poisoning may provide useful information to improve prevention and treatment strategies.

Based on residents' survey data in Seoul, this study attempts to empirically answer to four research questions regarding neighborhood relations (NR) which are necessary for community building: How important NR is compared to other social relations, what factors establish NR, how large NR's geographical extent is, and what are major meeting places among neighbors. A series of statistical analyses demonstrates that characteristics of NR vary greatly by family life cycle. In the stage of couple without child, NR has no significant meaning. NR becomes important from the stage of child care, and it is formed through the medium of children, particularly children's schools in the stage of child of elementary school as well as secondary schools. As the result, NR's geographical boundary extends beyond residential block or multi-family housing (apartment) estate while cafe and restaurant serve as dominant meeting places in these life cycle stages. On the contrary, after children are married and leave home, casual encounters resulted from spatial proximity become an important cause of NR. Likewise neighbors' geographical distribution is relatively concentrated within residential block or apartment estate, while community facilities play a role of meeting places as originally planned and designed.

The mature human braun contains over 10 billion nerve cells (neurons), whose functions are directly related to the acquisition, transfer, processing, analysis, and utilization of all the information. There are also billions of glial cells, which serve primarily to support and to maintain the integrity of the neuron network and to synthesize an essential fatty strucfure, myelin. In the human brain DNA content therefore cell number rises rapidly until birth and then more slowly until $5{\sim}6$ months of age, when it reaches a maximum. While glial cells may be replaced, the more important nerve cell neurons can never be replaced once they are formed. Humans are born with their full complement of neurons and every neuron is as old as each individual. Thus prenatal malnutrition can seriously affect a person's entire life by severely inhibiting the production of neurons before birth.It has been demonstrated that in humans severe malnutrition during the fetal period and in infancy is associated with intellectual impairment. Severely malnourished children have brains smaller than average size and have been found to have $15{\sim}20%$ fewer brain cells than wellnourished childen. There is growing body of literature pointing to malnutrition as a cause of abnormal behavior as evidence that suggests these abnormalities may produce chromosomal damage that may persist forever. Although cognitive development in children is affected by multiple environmental factors, nutrition certainly deaerves more attention than it has received.
