Female marriage immigrants have increased since the mid-1990s in Korea. Thus, their adaptation to Korean society has been a big social issue in Korea. There are a lot of academic researches on their adaptation to Korean society so far. We cannot sufficiently understand general main factors of their adaptation to Korean society because of methodological problems in the studies on the female marriage immigrants. Particularly, there are very few studies on female marriage immigrants' adaptation to their communities. This study analyzes determinants of female marriage immigrants' adaptation to their communities, using stepwise multi-regression. Data are collected from questionary survey on female marriage immigrants in Seoul, Gyeong-gi, Daegu, Gyeong-buk, Gwangju, Jeon-nam. Dependent variables are community life, spatial cognition and activities, and neighborhood relationship. Each dependent variable is analyzed with 30 independent variables through stepwise multi-regression. As a result, 16 positive determinants and 2 negative ones are selected. Positive determinants are resident identity, age, adaptation to home, number of Korean friends and same nationals' friends in Korea and so on. But, Korean language fluence is not selected as a significant factor. This is different from a general recognition. As exiting researches, the importance of social network and adaptation variables is also identified in this study.

To know the differences between health concern, health behavior, and subjective health cognition in urban and rural area, author used the correlation analysis between variables and wanted to provide basic data for public health service to support appropriate health care, health maintenance, and health promotion in community. Data collection were done in JeonBuk area from September 10 to October 10, 2001, and subjects were above 20 years old adult. 350 and 250 subjects were from urban and rural area by random sampling, respectively. Questionnaire were completed by interview with direct or self-recording type. Research tool was questionnaire with health concern, health behavior, and subjective health cognition, and data collected were analyzed into descriptives, crosstabs, T-test, ANOVA, Pearson correlation coefficient by SPSS 10.0 program. The results were as follows: 1. Health concern was 9.0% for upper group, 39.1% for middle group, 51.9% for lower group in urban area, and 10.1% for upper group, 41.0% for middle group, 48.8% for lower group in rural area. Health concern for middle and lower group was totally high percentage, and rural area had higher health concern than urban area. 2. Health behavior in both urban and rural area was statistically significant(p<0.01). Women who had higher age and with spouse had high degree of health behavior, and urban area had totally high score for health behavior compared to rural area. 3. Subjective health cognition was 71.0% for health, 29.0% for non-health in urban area, and 61.3% for health, 38.7% for non-health in rural area. Percentage of health group was higher in urban area than in rural area. 4. Degree of health behavior by health concern was statistically significant only in rural area. That is to say, the higher health concern had the higher degree of health behavior in rural area. Subjective health cognition by health behavior was totally significant correlation with health behavior in urban and rural area(p〈0.05). That is to say, the higher health behavior in urban and rural area had the higher subjective health cognition. 5. For correlations between 3 variables, there was significant correlation between health behavior and subjective health cognition in urban area (p<0.01). There were correlations between health concern and health behavior, health behavior and subjective health cognition(p<0.05). Considering above results, the higher health behavior had the higher subjective health cognition in urban area. The higher health concern had the higher behavior, and the higher health behavior had the higher subjective health cognition in rural area.

Purpose : To know the smoking status of regional residents and to contribute the development of smoking education program by analyzing the related characteristics and affecting variables. by convenience sampling of total 1,300 regional residents in Daegu. Method : The investigation was conducted with 1,204 residents in mid to small urban area of Gyeongsangbukdo. for 3 months from April 1, to June 30, 2007. Results : 1) The current smoking rate of test subjects was 19.3% and 63% responded as non smoker, and 17.1% of test subjects responded as currently stopped smoking. 2) The smokers' age that habitually started smoking resulted to show the highest distribution at their age of $20{\sim}29$ by including 49.3% in 446 smokers, and 39.6% in ages younger than 19 years old. 3) The subjective health status of test subjects was found to be healthy in 65.1% of nonsmokers. 4) The increase of stress along with the increase of depression significantly had large effects on smoking rate. 5) When the regression analyses were conducted, test subjects' sex, age, religion, current residing area, occupation, the level of health status, the level of stress and the level of depression found to have significant effects, and the influence of these variables was 27.4% by showing an overall significance. Conclusion : Primarily, the average smoking rate of regional residents was slightly decreased, but the smoking rate in juveniles, university students, professional workers, office workers, labor workers and women were found to be increased. Therefore smoking prevention and stop smoking policies have to be enforced with the development of more effective education programs. Secondly, the health status especially the increase of stress along with the increase of depression significantly had large effects on smoking rate. So, it is considered that the responsible government, related organizations and experts should make efforts not only for the improvement of health and but also for the establishment of stress and depression solving measures. Thirdly, the supports and willingness of government and local government for substantial practicing the development of smoking prevention and stop smoking enforcement policy education programs have to be advanced with the systematic backup as the first step of improving health of national peoples.

Maize plants, grown on a German soil and a Korean soil which had treated with benzene-ring-labelled $^{14}C-Bentazon$ (5.02mg/kg) immediately before planting (T-0), took up $36.0{\sim}42.8%$ of the radioactivity present during a 21 day growing period. Plants grown on the same soils $(4.79{\sim}4.84mg/kg)$ which had been treated with Bentazon and pre-incubeted for 105days absorbed $8.2{\sim}14.2%$ (T-1) of the radioactivity. Plants grown in soils $(5.56{\sim}7.95mg/kg)$ treated with Bentazon which had been incubated for 105 days and then exhaustively extracted with distilled water and/or 0.01 M $CaCl_2$ to produce non-extractable residues (T-2) took up $1.8{\sim}2.3%$ of the radioactivity. The distribution of the absorbed radioactivity ranged from 2.7 to 9.7% in shoots and from 90.3 to 97.3% in roots. Extraction of maize roots revealed that $39.1{\sim}51.3%$ of the radioactivity was bound in T-0 and $55.7{\sim}63.1%$ was bound in T-1, This suggests hat polar metabolites and parent Bentazon might be present as conjugates.

Purpose: We aimed to investigate trunk angle and muscle activation of the extremity and back to evaluate the effect of chest compression on work-related musculoskeletal disorders in 119 emergency medical technicians (EMTs). Methods: Eighteen 119 EMTs performed 2-minute chest compression without interruption on a cardiopulmonary resuscitation manikin, during which we measured changes in the trunk and shoulder joint angles, muscle activation (triceps brachii, biceps brachii, erector spinae, gluteus maximus, pectoralis major, rectus abdominis, and rectus femoris) and chest compression accuracy. Results: The decrease in trunk angle by trunk muscle activation was the highest in event 2, the major direction of chest compression. Both shoulder joint angles had no significant difference. Muscle activation of the triceps brachii (p < .01), biceps brachii (p < .05), rectus abdominis (p < .05) and rectus femoris (p < .01) significantly increased during the compression phase compared with the decompression phase, with the rectus femoris showing an increase of 19%. Muscle activation of the erector spinae significantly increased in the decompression phase compared with the compression phase (p < .01). Conclusion: 119 EMTs mainly use the triceps brachii, biceps brachii and pectoralis major muscles during chest compression.

This paper aims to investigate the characteristics of location and business-services networks of venture firms in Daegu region. The regional venture firms are small scale and consist of mainly R&D investment and license new-technology in the category of soft-ware. Since the mid-1990's the firms that were founded by people with higher education and career experience seek diverse growth strategies. those firms concentrate in some regions of dalseo-gu and buk-gu. There are a few difference by types of firm-business, but, on the whole, the princepal location factors of venture firms are accessibility of research institute and university, easy information availability, and use of moderate land. In regard to networks with client firms, the venture firms determine whether to transfer. The result of the characteristics of networks between regional venture firms and business-service enterprises is as follows; the regional venture firms utilize small number of business-service enterprises and use mainly information processing and other computer operation related services and professional, scientific and technical services. In business-service be used by regional venture firms, the frequency of information processing and other computer operation related services, research and development, business support services is much, while the frequency of professional, scientific and technical services is little. Business-service enterprises are distributed mostly in Daegu region and are used owing to lack of technology and knowledge.

Damyang Wetland Reserve with $980,575m^2$ area is located in Damyang-gun, Jeonlanam-do and Buk-gu, Gwangju Metropolitan City. The purpose of this paper is to divide Damyang riverine wetland into several geomorphic units, to analyze their sediments, and to categorize small ecosystem units composing riverine wetland. Riverine wetlands are classified into three types such as riverbed-, floodplain-, and abandoned-channel-wetland, and Damyang riverine wetland belongs to riverbed-wetland type. In this paper to categorize small geomorphic units of riverine wetland, we divide small geomorphic units from aircraft images analysis, and modify and supplement them following field survey results. Damyang Wetland Reserve is categorized into 22 ecosystem units. That physical and chemical properties of their sediments are different spatially, implicate that inorganic environment of Damyang riverine wetland ecosystem is very extensive. On the basis of the results of this study, policymakers will be able to design a strategy which manage Damyang Riverine Wetland Reserve more effectively, and for them interdisciplinary researches on relationships between various fluvial landforms and various lifeforms inhabiting them in Damyang Riverine Wetland Reserve are required.

This study was conducted among 831 industrial workers in Gumi City in Gyung-Sang-Buk Do for the purpose of acquiring knowledge to improve quality of life though industrial workers' oral health promotion. Oral examination and questionnaire surveying were used to evaluate workers' oral health state and subjective health state and analyze their effect on quality of life. 1. The number of workers in the study were 831 in all; there were more males who accounted for 74.6%. 43.7% of the subject were 29 years old, accounting for the largest age group. Their academic backgrounds are 53.6% workers who graduated from high schools or lower educational institutions, and 46.4% workers who graduated from college or higher educational institutions. 80.7% of the subjects replied that their economic state belonged to the middle class. Their job classification indicates that 70.2% were working in production and engineering fields and that the seniority of 55.3% workers was less than 55.3%. 2. The result of evaluating the effects of oral health state on individual well-being and quality of life using OHIP indicates that younger people, singles(p<0.01) than the married, those in worse economic situation and those with shorter seniority(p<0.01) had higher effect of oral health state on quality of life. In addition, those whose health or oral health was not good (p<0.01), those with liked tough texture of food and snacks(p<0.05), those with more frequency of drinking(p<0.01) and those with more smoking tended to have higher effect of oral health state on daily life or quality of life. Besides, OHIP confirmed that oral health state is a measurement tool that can evaluate its effect on individual well-being and quality of life. The suggestion for future studies is to develop Korean style OHIP that can be used conveniently and efficiently by expanding the subject area up to the whole country and validating the samples gained from random sampling.
