  • The purpose of this study is to analyse the factors affecting rehabilitation of physically disabled persons . Data were collected from 118 physically disabled persons who were registered at facilities for disabled persons by an interview surevey Conducted from October 17 to October 26, 1988. The three facilities for the survey were selected by stratified random sampling. The results were as follows : 1. Using factor analysis, 10 variables were-grouped into 4 factors : physical need, need for social problem-solving, need for social interaction and educational need. The proportion of variance explained by these factors was $58.3\%$. 2. Age, religion and job were significantly related to the functional life scale score, but other variables were not. 3. Family APGAR score and severity of disability were significantly rotated to the functional life scale score. 4. From the multiple regression analysis on rehabilitation of the physically disabled person, the following: three variables were statistically significant : age, severity of disability and family functioning. These results suggest that age, severity of disability and family functioning variables are important factors for rehabilitation of physically disabled persons. Since the family functioning variable can be controlled by care, rehabilitation team should monitor the variable closely to improve the efficiency of rehabilitation. Because of their implication for further study, some variables, other than those considered here, are needed for studying rehabilitation of physically disabled persons.

  • This study investigated the extend to which the facilities satisfactorily accommodate people with different disabilities and their specific needs for improving the facilities. Systematic interviews were conducted with 90 disabled people using the non-propertionate stratified cluster random sampling method. Frequency analysis, Chi-square tests, Duncan tests, and analysis of variance(ANOVA) were employed for data analysis. The findings indicated that the respondents' assessment of accommodations and needs for improving accommodations differed by the type of disabilities. People with physical disabilities were the least satisfied with stairs, followed by seating in stadiums and/or theaters. For people with visual disabilities, the lack of guidance and information facilities was the most difficult problem. People with hearing disabilities often pointed out difficulties in using public telephones. meanwhile, people with physical disabilities asked for easy access to assistive devices and improved mobility-related circumstances. yet people with visual disabilities expected to improve way-finding relevant issues, such as detectable warnings on walking surfaces and guidance and information facilities, whereas people with hearing disabilities desired to develop hearing-aid equipments, such as TDD and assistive listening systems.

  • Background: Understanding and enhancing change capabilities, including Practice Adaptive Reserve (PAR), of Community Health Centers (CHCs) may mitigate cancer-related health disparities. Materials and Methods: Using stratified random sampling, we recruited 232 staff from seven CHCs serving Asian Pacific Islander communities to complete a self-administered survey. We performed multilevel regression analyses to examine PAR composite scores by CHC, position type, and number of years worked at their clinic. Results: The mean PAR score was 0.7 (s.d. 0.14). Higher scores were associated with a greater perceived likelihood that clinic staff would participate in an evidence-based intervention (EBI). Constructs such as communication, clinic flow, sensemaking, change valence, and resource availability were positively associated with EBI implementation or trended toward significance. Conclusions: PAR scores are positively associated with perceived likelihood of clinic staff participation in cancer screening EBI. Future research is needed to determine PAR levels most conducive to implementing change and to developing interventions that enhance Adaptive Reserve.

  • The purpose of this study was to provide the basic data needed for developing comprehensive child edu-care programs that fits the regional needs. Subjects of the survey were the teachers of child edu-care centers in Daejeon. 95 teachers were selected from 20 child edu-care centers, using stratified random sampling method, from all of five municipal districts of the city. Gathered data were analyzed using SPSS 10.0 for reliability, factor analysis, frequency and percentile, mean, standard deviation, paired samples t-test and F-test. The summary of the findings were as follows: First, the result of survey on the child edu-care facts showed that the most child edu-care centers had the focus on caring and education programs of children, while emotional supports for family services and community social services were rather secondary importance. Therefore, to achieve the comprehensive service programs, child edu-care services should be harmonized by the education and welfare approaches. Second, centered around teacher's request, comprehensive child edu-care program that fits the regional characteristics focuses on family service; thus the program requires family group consulting, parents education etc., as well as focusing on community service to utilize local community's human, physical resources and to strengthen the tie between local community and child care services.

  • The purposes of this study were to identify leadership competences of rural leaders and to analyze leadership competency of leaders. The study carried out by questionnaire and focus group interview on expert panels. To analyze leadership competency, the data was collected from 273 rural leaders by stratified random sampling. SPSSWIN/ver10 program was used for analyzing data with t-test and IPA method. The study suggests twenty low types of leadership competences which were information, vision, decision making, motivation communication, education residents, managing residents, loaming, flexibility, problem solving, presentation program management, customer orientation service knowledge, making relationship, creative idea, business understanding, brand development, conflict resolution negotiation, assessment, business management, coaching and feed back. Whereas leaders with middle school educational career required developing program management, maintaining achievement and benchmarking, leaders with high school were morel likely to develope self-learning, to benchmark their knowhow and brand development competency. Whereas leader with less low years experiences as leader have been considered as developing coaching/feedback brand development and program development, leaders with more five years as leader should consider developing benchmarking, resident education, and brand development. The study suggests that the extension agents on public should develop leadership program according to the competency differences of leaders.

  • Objectives This study was aimed to examine cold hypersensitivity tendency in the hands, feet and abdomen according to Sasang constitution among Koreans. Methods Multi stage stratified sampling was conducted for random selection of 1,100 participants aged ${\geq}19years$, based on sex, age, region in Oct.2010. Cold hypersensitivity was measured using a questionnaire to score the extent of cold hypersensitivity in the hands, feet, abdomen. Subjects' constitution was diagnosed by Korea Sasang Constitutional Diagnostic Questionnaire (KS-15). The cold hypersensitivity scores according to Sasang constitution were analyzed using logistic regression and one way ANOVA. Results On the one way ANOVA, Soeumin group's cold hypersensitivity in the hands and feet scores were significantly higher than those of Taeeumin and Soyangin groups. However, there was no significant difference in the abdominal cold hypersensitivity scores by constitution. The regression analysis, adjusted for age, sex, and sociodemographic variables, showed that Soeumin group had significantly higher cold hypersensitivity effects of the hands (${\beta}=0.105$, p = 0.002) and feet (${\beta}=0.099$, p = 0.003) than Taeeumin group. Conclusions Soeumin group significantly had higher cold hypersensitivity scores in the hands and feet than Taeumin and Soyangin group.

  • Quantitative information on biomass and available nutrients are essential for developing sustainable forest management strategies to regulate atmospheric carbon. An attempt was made at Chilapatta Reserve Forest in Duars region of West Bengal to quantify its above and below ground carbon along with available "N", "P" and "K" in the soil. Stratified random nested quadrats were marked for soil, biomass and litter sampling. Indirect or non-destructive procedures were employed for biomass estimation. The amount of these available nutrients and organic carbon quantified in soil indicates that the forest soil is high in organic carbon and available "K" and medium in phosphorus and nitrogen. The biomass, soil carbon and total carbon (soil C+C in plant biomass) in the forest was 1,995.98, 75.83 and $973.65Mg\;ha^{-1}$. More than 90% of the carbon accumulated in the forest was contributed by the trees. The annual litter production of the forest was $5.37Mg\;ha^{-1}$. Carbon accumulation is intricately linked with site quality factors. The estimated biomass of $1,995.98Mg{\cdot}ha^{-1}$ clearly indicates this. The site quality factor i.e. tropical moist deciduous with optimum availability of soil nutrients, heavy precipitation, high mean monthly relative humidity and optimum temperature range supported luxuriant growth which was realized as higher biomass accumulation and hence higher carbon accumulated.
