Objective: The purpose of this study was to differences of foot plantar pressure balance and lung capacity according to cervical posture in adults. Method: The subjects consisted of 33 adults in their 20s and 50s who use M centers in B-gu and H-gu, B-City, and they measured foot plantar pressure balance and lung capacity according to cervical posture (cervical normal curvature posture, cervical flexural posture) in adults. Results: In this study, the difference of foot plantar pressure balance according to cervical posture were analyzed. In the difference between left and right foot pressure balance. It was 1.50% increased in the cervical flexural posture than in the cervical normal curvature posture, and a statistically significant difference was observed. In the difference between the anterior and posterior foot pressure balance. It was 4.28% increased in the cervical flexural posture than in the cervical normal curvature posture, and a statistically significant difference was observed. The difference of lung capacity according to cervical posture were analyzed. In the PEF, It was 58.63 l/min decreased in the cervical flexural posture than in the cervical normal curvature posture, and a statistically significant difference was observed. In the FEV1, It was 0.15 ℓ decreased in the cervical flexural posture than in the cervical normal curvature posture, and a statistically significant difference was observed. Conclusion: The results of this study suggest that had a positive effect on differences of foot plantar pressure balance and lung capacity at cervical normal curvature posture in adults. In future research, itis believed that research on the elderly who have collapsed the normal curvature posture due to aging, as well as teenagers whose normal curvature posture due to the use of smartphones, will contribute to the balance of foot pressure and improvement of the right cervical habits. In future studies, it is also believed that it will be necessary to measure lung capacity after performing exercise according to the cervical posture, thereby providing sufficient oxygen during exercise to enhance the persistence and efficiency of the movement.

Facing reconfiguration of world economic order in the process of globalization and changes in domestic economic and social conditions, Japan has experienced a rapid inflow of foreign immigrants and hence a restructuring of labor market and ethic and cultural mixture. This paper explores contexts of inflow and social and spatial characteristics of immigrant workers in Japan. Uneven regional development on the global level and shifting to flexible accumulation regime, depletion of previously underutilized labor resource, better-educated youth and shrinking and aging of Japanese populace on the national level can be pointed out as important elements of immigration contexts. This paper also explains the hierarchizaton of labor market and differentiation of spatial distribution of immigrant workers in Japan in terms of visa condition and nationality. In particular, focusing on the case of Hiroshima prefecture, this paper analyzes residential differentiation of immigrants according to their nationality. Finally, it finds out some problems which immigrant workers have confronted in Hiroshima region.

Morphological characteristics indicating agronomic features and yield components (trunk length, trunk diameter, thickness of bark, pith density, dry-matter percentage of pith and starch concentration in pith) of sago palms (Metroxylon sagu Rottbøll) were compared between the 27 populations grown in the islands in Southeast Asia (West Sumatra, South Sumatra, West Java, Southeast Sulawesi, Ternate, Halmahera and Seram in Indonesia) and the 20 populations grown in Melanesia (West Papua in Indonesia, East Sepik and New Ireland island in Papua New Guinea). The average starch yield calculated based on the yield components was $310kg\;plant^{-1}$ and $244kg\;plant^{-1}$ in the islands in Southeast and Melanesia, respectively. The variation of starch yield in Melanesia (CV: about 80%) was larger than that in the islands in Southeast Asia (CV: about 60%). The difference in starch yield in the islands in Southeast Asia was mainly attributed to the trunk diameter breast height and the dry-matter percentage of pith. In contrast, the differences in trunk length and dry-matter percentage of pith mainly accounted for the difference in starch yield in Melanesia. The sago palms in the islands in Southeast Asia had a comparatively thick and short trunk and those in Melanesia had a comparatively thinner and longer trunk. However, the average pith dry-matter yield was almost same level as $400kg\;plant^{-1}$ in both the islands in Southeast Asia and Melanesia. The difference in starch yield between the two areas was attributed to the difference in starch concentration in pith, 77% and 58% in the islands in Southeast Asia and Melanesia, respectively.

Background : The goal of this study was to examine the health behaviors of nurses and provide basic information on health promotion for nurses. Materials and Methods : A self-administered questionnaire survey was completed by 340 nurses working at a university hospital in Daegu, Korea from March 6 to March 30, 2006. The questionnaire included demographic characteristics, working environment, health behaviors, self-assessed health status, and the practice of health promotion activities according to the work group(shift group vs. non-shift group). Results : There were significant differences in 'regular diet', 'drinking', 'ordinary health management', 'regular exercise', 'leisure activities', 'rest', and 'feeling of fatigue' between the two groups. The score for the practice of health promotion activities of the non-shift group was 121.9, which was higher than the 115.4 for the shift group. By field of practice of health promotion activities, there were significant differences in 'self-realization' and 'nutrition' between the two groups. Conclusion : The shift group did not appear to have enough time to take care of their health. It is therefore important to provide a working environment in which nurses are encouraged to increase their interest and efforts to maintain healthy behaviors. In addition, programs for education and training should be developed to help nurses adopt healthy life styles and enhance their self-esteem.

This work carried out to analyze the physicochemical properties and investigate the assessment of heavy metal contamination of stream sediments of the Yudeung and the Gab streams in the Daejeon area. The pH of stream sediments of the Yudeung stream shows the range of weak acid and weak alkaline. Most of stream sediments contain about 80% sand grain and have low water and cation retention capacity. Hence the stream sediments are not suitable fur various plans to grow up. The analysis of heavy metals in the stream sediments shows that the concentration of Pb, Cr and Cd increases from upstream to down stream. It is likely that the trend has a relationship with the water. Contamination of stream water. The authors recommend that clay materials be replenished in the stream sediments to increase the self-purification capacity and to make the suitable condition for growing up of various plants, and that water quality of the stream which can Influence into the contamination of stream sediments be monitored.

Through this study, the purpose of this study is to harmonize the quality assurance system of diagnostic radiation generator inspection bodies with current international standards, standardize the diversity of inspection bodies, provide consistent inspection services to medical institutions, and improve review efficiency of regulatory agencies. We compared and reviewed the quality assurance systems of all domestic diagnostic radiation generator and defense facility inspection bodies. For international harmonization, we reviewed international and domestic and international standards, including ISO/IEC 17020, and added and reflected the requirements of regulatory agencies. The quality assurance systems of all inspection bodies included all required items in compliance with ISO/IEC 17020, but some of the quality procedures showed differences. Standards were drawn up through expert meetings for items where differences were compared and analyzed, and rules for safety management of diagnostic radiation generators and amendments to these regulations were proposed. The results of this study are expected to improve the operational efficiency of inspection bodies and the work efficiency of regulatory agencies for inspection bodies, and international harmonization in accordance with international standards such as ISO/IEC 17020 should be continuously maintained.

Purpose：To investigate the effect of the home exercise program on pain, scoliosis, pelvic alignment of low back in chronic back pain patients, and suggest optimal method for home exercise program. Methods：I divided into two groups who has chronic back pain; one is control group who was given a treatment at the hospital only and the other is experimental group who did another exercise after treatment at the hospital, and there were 10 people in each group. The manual therapy were given to all the patients in each group after applying a stupe and an electric treatment, but the experimental group conducted another exercise program at homes. All the exercise programs were applied to patients 12 times for 4 weeks totally. Results：SPSS for win version 12 was used for statistic analysis and independent t-test was used to find changes between two groups. VAS scale was used to show changes in pain between each group. The grade of pain was decreased between pre&post test to -5.60 in control group and -4.80 in experimental group but there wasn't significant difference between each group. Cobb's degree was used to compare the changes of scoliosis in lumbar and it was improved in each group but there wasn't significant difference between each group. The measurement of pelvic misalignment was decreased between pre&post test to -1.00 in control group and -2.00 in experimental group but it wasn't enough to show significant difference between each group. Conclusion：As you read the results above, for a chronic low back pain patient, application of the manual therapy showed that it has effect on decrease of low back pain, improvement of scoliosis in lumbar and pelvic misalignment. However, the effect of home exercise treatment was not sure about improvements for chronic low back pain patient. So I think there should need further study about the effect of home exercise treatment except the treatments at hospital and the thorough education for the exercise of lumbar should be done before the study for the accurate experiment.

Purpose: We conducted a descriptive correlational study to determine a relationship between nurses' awareness of good death and attitudes toward terminal care, which in turn could be used as basic data for improvement of the quality of terminal care at geriatric hospitals. Methods: From April 3, 2013 through April 22, 2013, data were collected from 230 nurses working at geriatric hospitals. Results: Nurses' attitudes toward terminal care showed no significant correlation with awareness of good death, but it was positively correlated with a sense of closeness, a subfactor of awareness of good death. There was negative correlation between emotions regarding a deathbed, a subfactor of attitudes of nurses in charge of terminal patients, and awareness of good death. We found positive correlation between terminal care performance and awareness of good death. Conclusion: This study warrants the need for nursing education catered to characteristics of geriatric hospitals and development of diverse intervention strategies to help them to attain a positive attitude toward death by familiarizing themselves with the concept of good death and enhancing job satisfaction.

The possible role of nitric oxide (NO)-induced cell division was investigated to explain the physiologycal effects of a NO donor, sodium nitroprusside (SNP) on the growth of primary leaves in chinese cabbage seedling plants. Exogenous treatment of SNP to chinese cabbage plants for 8 days at different concentrations (0, 200, 500 and 1000 ${\mu}M$) affected the leaf growth in a concentration-dependent manner, showing a maximum growth at $200\;{\mu}M$. In accordance with leaf growth responses, the chlorophyll and soluble protein contents increased strongly to 142% and 134% of control at $200\;{\mu}M$ SNP, respectively. However, a very little decrease in chlorophyll and a 13%> decrease in protein were observed at $1000\;{\mu}M$ SNP. In addition, the content of DNA and RNA also increased maximumly to 142% and 139% of the control at $200\;{\mu}M$ SNP, respectively, whereas they decreased to 80% and 84% of the control at $1000\;{\mu}M$ SNP. With respect to the development of enzymes related to cell wall synthesis, $200\;{\mu}M$ SNP led to the maximum activities in both phenylalanine ammonia-lyase (212% of the control) and guaiacol peroxidase (134% of the control). However, the activities of both enzymes were not modified significantly at $1000\;{\mu}M$ SNP. In conclusion, these results suggest that the enhancement of leaf growth in chinese cabbage plants by SNP at the effective concentration was probably due to the NO ability in the induction of cell division.
