Objective : The objective of this study was to survey the job satisfaction and turnover intention of 119 emergency medical technicians who are fire fighters and, at the same time, provide emergency patients with first aid, to examine the correlation between their job satisfaction and turnover intention, and to provide basic materials for the human resource management of 119 emergency medical technicians. Method : The survey was conducted with 152 119 emergency medical technicians working at fire stations in an area of Gyeonggi-do during the period from July 15 to September 14, 2009. Job satisfaction was measured with a tool developed by Kim Sun-sim and Kwon Hye-ran (2002) based on the Index of Work Satisfaction, and turnover intention with the tool developed by Becker (2002) and translated and used by Cho Yeong-sook (2002). The questionnaire was composed of 11 questions on general characteristics, 35 on job satisfaction, and 4 on turnover intention, so a total of 50 questions. The reliability of the questionnaire was Cronbach's ${\alpha}=0.922$ for job satisfaction and Cronbach's ${\alpha}=0.854$ for turnover intention. Using SPSS 14.0, we obtained frequencies, percentages, means, and standard deviations, and performed independent two-sample t-test, one-way ANOVA, and Pearson correlation analysis, and Cronbach's ${\alpha}$. Results : 1) The mean score of the 119 emergency medical technicians' job satisfaction was 2.71, and that of their turnover intention was 2.64. By area of job satisfaction, the mean score was 3.44 for the area of job itself, 2.92 for the interaction area, 2.67 for the organizational demand area, 2.64 for the autonomy area, 2.14 for the wage area, and 1.91 for the working condition area, showing that emergency medical technicians were generally satisfied with their job itself but not with their working condition. 2) As to difference according to the 119 emergency medical technicians' general characteristics, statistically significant difference was observed in job satisfaction according to license type (F = 4.729, p < .010), and in turnover intention according to position (F = 3.768, p < .025). 3) The 119 emergency medical technicians' job satisfaction and turnover intention was in a negative correlation with each other (r = -.44, p < .000) in general, and by the sub-areas of job satisfaction, the correlation with turnover intention was high in order of the autonomy area (r = -.42, p = .000), interaction area (r = -.42, p = .000), job itself (r = -.35, p < .000), organizational demand area (r = -.30, p = .000), wage area (r = -.23, p = .000), and working condition area (r = -.21, p = .008). Conclusion : The 119 emergency medical technicians' job satisfaction showed a negative correlation with their turnover intention. This suggests that turnover intention can be reduced by improving job satisfaction. Furthermore, 119 emergency medical technicians' job satisfaction was high with the job itself, showing their high pride in their job, but was low with working condition and wage. Thus, it is necessary to enhance their job satisfaction by improving the 24-hour work system through supplementing manpower, compensating for overtime works, adjusting work hours per week, etc. These results are expected to be useful in making human resource management plans to lower turnover intention by enhancing 119 emergency medical technicians' job satisfaction.

This study was done to develop a Maternal Identity Scale for Pregnant Women and to test the validity and reliability of the scale. A convenience sample of 161 pregnant women were asked to complete the MISP questionnaire which consisted of 45 item, this was done from December 20, 1995 to January 15, 1996. The research procedure were as follows. The first step was to identify a conceptual definition of maternal identity using Robin(1984)'s maternal identity and maternal experience during pregnancy. The second step was to operationalize the maternal identity, that is, perception of image possible of selves as mother, maternal role play by imagination, and the experiences of various emotional responses which are embedded in the mother-fetus dyad. The third step was item development which resulted in 45 items as appropriate measurement of maternal identity are except for the perception of image possible of selves as mother. The result findings were as follows : 1) Four factors for MISP (finally 40 items) were extracted through the principal component analysis and varimax rotation, and these contributed 49.3% of the variance in the total score. All 40 items in the scale loaded above .43 on one of 4 factors. 2) Each factor was named : factor 1 was named maternal role imagery and has 10 items, factor 2 was named happiness and has 11 items, factor 3 was named maternal fetal interaction and has 10 items, and the last factor 4 was named negative emotion and has 9 items. 3) Cronbach's -alpha coefficient for internal consistsncy was .92 for the total 40 items and .89, .90, .86, .78 for the four subscales in that order. Recommendations are suggested below : 1) The developed MISP be used to assess maternal readiness in pregnancy. 2) Replication study be done to test validity and relaibility. 3) For the overall measure of Maternal Identity in Pregnancy, scale for the perception of image possible of selves as mother, and cognitive domain be reorganized for the maternal identity in pregnancy. 4) It is necessary to identify variables that influences maternal pregnancy. 5) It Is necessary to identify that maternal identity in pregnancy is a reliable index of motherhood, to do correlation studies on maternal identity and major maternal variables in maternal transition period, to reoperationalize the maternal identity in postpartum, and finally to designate a longitudinal study of the maternal identity changes or stabilities.

The purpose of this study was to find out the causal relationship between perceptual level of stress and health state according to Korean constitutions and to analyze that effect on the Korean constitution's health state. Subjects of this study were 87 out patient department of constitution at Kyung-Hee Oriental Medicine Hospital. Data were collected by using interview with Questionaire during 6 months from Feb. 2 to June 31, 1991. The Measurement tools used by this researcher were Go's The Questionaire of Identify about constitution, Lee's stress scale and Go's modified Cornell Medical Index which were approved it's reliability and validity. All of the questionaires of were used after pre- test. For the purposes of the study, the collected data were analyzed by frequency, t-test, ANOVA and Pearson correlation. And then this research's issue was tested by SAS program's ANCOVA. The findings of this study was summarized as follow. 1. There was significantly differences in stress perceptual level in Korean constitution. (F=9.68, P=.000). The So Em In (小陰人) were higher than the other constitution on stress perceptional level. 2. In health state, there was significantly difference among Korean constitution. (F=6.654, P=.002). Also the So Em In (小陰人) was lower than the other constitution at health state. Therefore, it was considerate that So Em In (小陰人) was higher perceptual level of stress than the other constitution and the resulting poor health state. 3. Stressful perception was effected on the health state, as a result inverted correlation was constructed between stress perception and health state. (r=-.6034, P=.0001) 4. After exclusion of stress perceptual level, each of the Korean Constitution's health state was not difference (F=1.01, P=.37). It was mean that differences of the Korean Constitution's perceptual level of stress effected on the health state. Bacause So Em In (小陰人) had higher perceptual level of stress than other constitution (F=9.687, P=.000), in proportion to that one's health state was poor. From the results of this study, it could be concluded that the higher stress perceptual level according to Korean constitution, the poorer health state. Further study in this area needs to be consideration that in order to coping with stress, researcher grope for quality nursing intervention with more accurative assessment about Korean constitution.

The purpose of this study was to examine the effect of game-centered empathy training on the prosocial behaviors of elementary schoolers in a bid to suggest how their prosocial behaviors could be boosted. The research questions were posed as below: 1. Does game-based empathy training improve the overall empathy of school children? 2. Does game-based empathy training have a better effect on the cognitive empathy of school children or their emotional empathy? 3. Does game-based empathy training enhance the prosocial behaviors of school children? The subjects in this study were 62 children in their fourth year of D elementary school in Eumseong-gun, north Chungcheong province. They were divided into an experimental group and a control group, and a survey was conducted before and after the experimental group under-went empathy training for about six weeks. The instrument used in this study was David(1980)'s Interpersonal Reactivity Index adopted by Park Sung-hee(1996) to suit school children. Another instrument was Park Sung-hee (1997)'s inventory to assess the prosocial behaviors of children. The collected data were analyzed by SPSS 10.0 for Windows program, and reliability analysis and t-test were employed. The findings of the study were as follows: First, as for the effects of the game-based empathy training on the overall empathy of the elementary school youngsters that included both emotional and cognitive empathy, both groups got lower scores in posttest than in pretest. The experiment produced unexpected results, as the experimental group got significantly lower scores. This fact indicated that the game-based empathy training was ineffective. Second, the game-centered empathy training didn't exercise any influences on their cognitive and emotional empathy. The experiment had a reverse impact on the cognitive and emotional empathy of the experimental group, which implied that the training served as a factor to deteriorate the two types of empathy, and the hypothesis posed in this study was rejected. Therefore, which type of empathy could make a better progress by being exposed to the training couldn't definitely be determined. Third, the game-based empathy training didn't serve to Improve the prosocial behaviors of the elementary schoolers. There was no change in the experimental group, and this fact signified that there's something wrong with the attempt to develop school children's empathy to step up their prosocial behaviors. Based on the above-mentioned findings, the following conclusion was reached: First, the game-centered empathy training had no effects on boosting the overall empathy of the school children. Second, the game-centered empathy training couldn't be said to be effective in improving either cognitive empathy or emotional one. From a viewpoint of relativity, that could be said to affect emotional empathy more than cognitive one. Third, the game-based empathy training wasn't effective in improving prosocial behaviors. Rather, that resulted in interrupting the promotion of prosocial behaviors.

The purpose of this study is to survey and analyze the operating state and characteristics of domestic and foreign green care, prioritize the facilities and programs for green care introduction through expert survey of importance, and thereby to provide a basic material for introducing green care in facilities in Rural Development Project districts, including domestic rural experience facilities. Domestic and foreign literature was analyzed in order to classify the necessary facilities programs, of green care, and the analysis results were modified and supplemented through Expert Delphi Survey. Based on the results, AHP based importance survey was conducted. In terms of the facilities and programs for green care introduction, necessary facilities (H/W) were categorized into four types (accommodation facility, resting facility, experience facility, therapy facility) and S/W programs into three types (learning experience type, therapy type, and care type). To verify the reliability of the AHP based importance survey, Consistency Index (C.I.) was analyzed. As a result, the C.I. value of nine respondents ranged from 0.000 to 0.083 so that the survey was found to have high consistency. The importance of S/W programs was 0.627, and that of H/W facilities was 0.373. For green care introduction, programs were found to be more important. Regarding the categories of necessary facilities, therapy facility had the highest value, or 0.348; experience facility 0.253; accommodation facility 0.211; resting facility 0.188. Therefore, therapy facility and experience facility were found to be important. In case of S/W programs, therapy type had the highest value, or 0.499, and learning experience type (0.255) and care type (0.246) were similarly important. Generally, the categories that had high importance values tended to show a remarkable difference in importance of their sub categories. In particular, facilities or therapy programs using natural ecology and forests were found to be highly important. In conclusion, it is required to actively review the introduction of active programs using resources, such as existing experience facilities and accommodation facilities and villages forests, and programs making the body and soul comfortable, such as natural ecology experience, Green Shower, and horticulture activity.

This paper makes an effort to compare the recently evolved soft classification method based on Linear Spectral Mixture Modeling (LSMM) with the traditional hard classification methods based on Iterative Self-Organizing Data Analysis (ISODATA) and Maximum Likelihood Classification (MLC) algorithms in order to achieve appropriate results for mapping, monitoring and preserving valuable coastal wetland ecosystems of southern India using Indian Remote Sensing Satellite (IRS) 1C/1D LISS-III and Landsat-5 Thematic Mapper image data. ISODATA and MLC methods were attempted on these satellite image data to produce maps of 5, 10, 15 and 20 wetland classes for each of three contrast coastal wetland sites, Pitchavaram, Vedaranniyam and Rameswaram. The accuracy of the derived classes was assessed with the simplest descriptive statistic technique called overall accuracy and a discrete multivariate technique called KAPPA accuracy. ISODATA classification resulted in maps with poor accuracy compared to MLC classification that produced maps with improved accuracy. However, there was a systematic decrease in overall accuracy and KAPPA accuracy, when more number of classes was derived from IRS-1C/1D and Landsat-5 TM imagery by ISODATA and MLC. There were two principal factors for the decreased classification accuracy, namely spectral overlapping/confusion and inadequate spatial resolution of the sensors. Compared to the former, the limited instantaneous field of view (IFOV) of these sensors caused occurrence of number of mixture pixels (mixels) in the image and its effect on the classification process was a major problem to deriving accurate wetland cover types, in spite of the increasing spatial resolution of new generation Earth Observation Sensors (EOS). In order to improve the classification accuracy, a soft classification method based on Linear Spectral Mixture Modeling (LSMM) was described to calculate the spectral mixture and classify IRS-1C/1D LISS-III and Landsat-5 TM Imagery. This method considered number of reflectance end-members that form the scene spectra, followed by the determination of their nature and finally the decomposition of the spectra into their endmembers. To evaluate the LSMM areal estimates, resulted fractional end-members were compared with normalized difference vegetation index (NDVI), ground truth data, as well as those estimates derived from the traditional hard classifier (MLC). The findings revealed that NDVI values and vegetation fractions were positively correlated ($r^2$= 0.96, 0.95 and 0.92 for Rameswaram, Vedaranniyam and Pitchavaram respectively) and NDVI and soil fraction values were negatively correlated ($r^2$ =0.53, 0.39 and 0.13), indicating the reliability of the sub-pixel classification. Comparing with ground truth data, the precision of LSMM for deriving moisture fraction was 92% and 96% for soil fraction. The LSMM in general would seem well suited to locating small wetland habitats which occurred as sub-pixel inclusions, and to representing continuous gradations between different habitat types.
