  • The purpose of this study is to examine the effects of the rural community planning focusing on the stepwise empowerment system in Jinan-gun, Jeollabuk-do province. This paper also tries to examine how this system affect the awareness for community planning and empowerment of the residents. The satisfaction of the people who join this program were also investigated. The subjects of the research were divided into two groups. Group A consisted of the people who join the system from the first stage, and group B consisted of the people who joined the fourth stage directly. The differences of the recognition, capability changes and satisfaction between two groups were compared and analyzed by questionnaires. The results of this research can be summarized as follows. The first, group A recognized the community planning system in Jinan-gun more positively than group B. They thought that it's very useful and beneficial for their community and this system should be continued further. The second, group A considered that they achieved bigger advancement in community design capabilities in terms of personal, relational and social aspects than group B. In addition, group A also showed higher satisfaction for rural community planning than group B. Based on the results, alternatives for rural community planning were drawn as follows. The first, considering that group A showed more positive responses, starting from the first stage is more stable way to succeed in rural community planning. Which means the critical condition of community design is not the community business but the improving the public awareness and community mind. The second, it's considered that the number of participation is proportional to the advancement of capability in community project, so improving residents' opportunity to participation in community design might be effective. The third, community leader is another critical condition. It is needed to pay more attention to the education for the rural community leader with good experience and capability of community affairs.

  • The kinetic studies of the reactions of $\alpha$-chloroacetanilides $(YC_6H_4NRC(=O)CH_2Cl;\;R=H\;(4)\;and\;CH_3$ (5)) with pyridines have been carried out in dimethyl sulfoxide at 95 ${^{\circ}C}$. The pyridinolysis rates are faster with 4 than with 5 whereas the aminolysis rates with benzylamines are faster with 5 than with 4. The Brønsted ${\beta}_X$ values are in the range from 0.30 to 0.32 and the cross-interaction constants, $\rho_{XY}$, are small negative values; $\rho_{XY}$ = -0.06 and -0.10 for 4 and 5, respectively. Based on these and other results, the pyridinolyses of $\alpha$-chloroacetanilides are proposed to proceed via a stepwise mechanism with rate-limiting addition of the nucleophile to the carbonyl group to form zwitterionic tetrahedral intermediate ($T^{\pm}$) followed by a bridged type transition state to expel the leaving group.

  • Purpose: The purpose of this study was to describe the status of the functional health literacy of the elderly living in a rural community and to identify the influencing factors on the functional health literacy. Methods: Subjects(n=238) aged over 60 years were selected for data collection. Functional health literacy was measured by Korean Health Literacy, which consisted of 15 items including eight numeracy and seven comprehension items. Descriptive statistics, t-test, ANOVA with Scheffe test, and stepwise multiple regression were used to analyze the data. Results: The mean score of total functional health literacy was $6.66{\pm}3.31$, numeracy was $3.52{\pm}1.76$, and comprehension was $3.41{\pm}2.10$. Of the subjects, 39.1% showed a low score below the median split. In the results of stepwise multiple regression, the factors affecting functional health literacy were basic literacy, age, number of chronic diseases, self-reported health status, and gender. These factors accounted for 33.0% of functional health literacy. Conclusion: These results suggest that interventions for improving functional health literacy are necessary to enhance elders' ability of self-care management. In addition, it is needed to take into account the individual characteristics of the subjects depending on their gender, age, and health status.

  • The primary objective of this study is to investigate the feasibility of an innovative surface-mount sensor, made of a piezoelectric disc (PZT sensor), as a consistent source for surface wave velocity and transmission measurements in concrete structures. To this end, one concrete slab with lateral dimensions of 1500 by 1500 mm and a thickness of 200 mm was prepared in the laboratory. The concrete slab had a notch-type, surface-breaking crack at its center, with depths increasing from 0 to 100 mm at stepwise intervals of 10 mm. A PZT sensor was attached to the concrete surface and used to generate incident surface waves for surface wave measurements. Two accelerometers were used to measure the surface waves. Signals generated by the PZT sensors show a broad bandwidth with a center frequency around 40 kHz, and very good signal consistency in the frequency range from 0 to 100 kHz. Furthermore, repeatability of the surface wave velocity and transmission measurements is significantly improved compared to that obtained using manual impact sources. In addition, the PZT sensors are demonstrated to be effective for monitoring an actual surface-breaking crack in a concrete beam specimen subjected to various external loadings (compressive and flexural loading with stepwise increases). The findings in this study demonstrate that the surface mount sensor has great potential as a consistent source for surface wave velocity and transmission measurements for automated health monitoring of concrete structures.

  • Purpose: This study were to examine the relationship among chronic pain, pain beliefs, pain coping, and fatigue and to define the main factors influencing chronic pain in the elderly. Method: Data were collected by self-reported questionnaires from 276 Korean elderly. Data analysis was done with SPSS 10.1 for descriptive statistics, t-test, ANOVA, Pearson Correlation Coefficient, and Stepwise multiple regression. Results: Chronic pain score was 5.45, which was slightly higher than the average. There were significant differences in chronic pain according to age, marital state, economic state, and duration of pain. There was a significant positive correlation between chronic pain and pain beliefs, passive pain coping, physical fatigue and mental fatigue. In addition, there was a significant negative correlation between chronic pain and active pain coping. Stepwise multiple regression analysis showed that 44% of the variance in chronic pain was significantly accounted for by passive pain coping(31%), pain beliefs(8%), physical fatigue(4%), and active pain coping(1%). Conclusion: These results suggested that pain beliefs, pain coping, and fatigue can be influencing factors on chronic pain for the elderly. Also, the findings can provide a basis for nursing intervention development to effectively manage chronic pain for the elderly.

  • This descriptive-correlational study was undertaken in order to examine if there were relationships between family support, compliance and life satisfaction in chronic arthritis patients. The sampling method was a non-probability, purposive sampling technique. The participants of this study were 92 volunteer adults. 1) who have been diagnosed as having chronic arthritis and 2) who were at the medical out patient clinic of one university hospital in Seoul between April 27th to May 12th 1987. The instruments used for this study were the Family Support Scale developed by Kang Hyun Sook, a Compilance Scale developed by the researcher and the Life-Satisfaction Index-Z developed by Wood et.al. Analysis of data was done using t-test, ANOVA, Pearson Correlation Coefficient and Stepwise Multiple Regression Analysis. The results of study were as follows; Hypothesis I; “The higher the family support, the higher the compliance” was accepted. (r=.2604, p<.01) Hypothesis II; “The higher the compliance, the higher the life satisfaction,” was rejected. (r=.1663, p>0.5) Hypothesis III; “The higher the family support, the higher the life satisfaction” was accepted. (r=.3914, p<.01) In addition, by using Stepwise Multiple Regression Analysis it was determined that the main influencing factors on the life satisfaction were family support, the number of inflammatory joints, compliance and pain level. These 4 main variables made it possible to explain 30.8% of the variance in life satisfaction. In conclusion, this study revealed that family support is an important factor that can improve compliance and life satisfaction in chronic arthritis patients.

  • Purpose: This study undertakes to identify factors influencing the perception university students in Korea hold toward having children. Method: A cross-sectional, descriptive study was conducted on 187 university students (79 males and 108 females) from one university located in a metropolitan area. Participating students completed a packet of self-report questionnaires on values concerning gender roles, marriage, family and children along with their personal demographic details. The resulting data were analyzed using t-tests, one-way ANOVA and Pearson's correlation coefficients as well as descriptive statistics. Stepwise multiple regression was performed to identify factors that most influenced the value of children held among university students. Results: The value of having children was negatively associated with the value of family, but positively associated with the value of marriage. In addition, the value of family had a negative relationship with the value of marriage, but a positive relationship with the value of gender role. Stepwise multiple regression found that the equation consisting of gender and value of marriage explained about 42.0% of the variance of the value of having children. Conclusion: Considering the findings from this study, programs promoting the positive values of marriage are required for university students to have positive values toward having children.

  • Recently, physical examinations have become an important strategy to reduce costs for individuals and society. Pre-physical counseling is important for an effective physical examination. However, incomplete counseling is being conducted because the demand for physical examinations is not predicted. Therefore, in this study, the demand for physical examination was predicted using text mining and stepwise regression. As a result of the analysis, the most recent text data showed a high explanatory power of the demand for physical examination. Also, large amounts of data have high explanatory power. In addition, it was found that the high frequency of the text "health food" reduces the number of health examination customers. And the higher the frequency of the text of the word "food", the lower the number of physical examination customers. However, when the word "wild ginseng" was exposed a lot on Twitter, the number of physical examination customers visiting hospitals increased. In other words, customers consume efficiently by comparing the health examination price with the price of consumer goods. The proposed research framework can help predict demand in other industries.
