The purpose of this study was to assess the rural women's general status in relation with low back pain. This survey was done after teaching them the prevention and treatment of low back pain with Meckenzie Method. 84 rural resident women including rural life guidance. The results were as follows. 1. The average age of rural were $35{\sim}50$ years old and the guidance's age were $21{\sim}25$ years old. The educational level of rural women were highest in primary school(46.67 %) and the home extension worker were college education(83.67 %). 2. 75 % of rural woman complained low back pain while 17.33 % of the home extension worker had back pain. 3. The home extension worker feel the necessity of the education in low back pain(100 %) while 88.89 % of the rural woman agreed. 4. All the rural women and the home extension worker had the concept of back pain and its prevention(100 %). 5. After this education, the confidence in prevention and treatment were each 78.79 % with rural women and 91.84 % with home extension worker. 6. The necessity for the treatment of low back pain were : first, the correction of posture, second, the activity posture correction, third, the supportive roll of back curve. 7. There were no statistical significant outcome specifically.

In industrial field, there are several operations where a horizontal unidirectional airflow is used to control airborne contaminants. When a worker is immersed in a uniform freestream, a recirculating airflow can be created downstream of the worker by the phenomenon of boundary layer seperation. If the contaminant source and the breathing zone are within this near-wake region, high exposure may occur. The investigation for the effect of contaminant source location on worker exposure was performed by using CFD(Computational Fluid Dynamics). The airflow field was numerically calculated by assuming a steady flow and using the standard $k-{\varepsilon}$ turbulence model. As the results were compared with experimental data, the applicability of CFD was successfully verified. Subsequently, the breathing zone concentrations of the worker were predicted and compared with experimental data. The effects of contaminant density and turbulence intensity of freestream on worker exposure were evaluated.

Political participation consciousness of social worker is changed and politics participation activity is putting forth with a bud. Currently, the systematic and scientific approach in study of social worker's the political participation is short. This study analyzes the present situation of political participation action and will present political participation action contents and direction in the future. This study may give practical meaning to the social welfare practice and educational scope about what we must do to become a political influence the group. The object of this study is 1229 people in choosing social welfare politics participation investigation committee data. A participation of Korean social worker appeared that a meeting or a demonstration is high when comparing the United States. Also, electioneers, and, government bureaucrat contact, financial contributions is a half experience. The strong variable in explaining social worker's the political participation was a politics efficacy, politics interest. Political efficacy and politics interest, a joining and a political behavior proposal of an association is a influenced factor. Through this result The Civic Volunteer Model is a theory to able to explain social worker's the political participation. Approach growing the political efficacy and politics interest is very important in activating politics participation. Role of a social welfare association or a group was important in order to induce politics participation and concentrate.

This research develops a framework for resolving time and worker conflicts in the Critical Chain Project Management (CCPM) method, expressed in the form of a Max-Plus Linear (MPL) system. Our previous work proposed a method for resolving time conflicts. However, in practical cases, both time and worker conflicts may occur. Hence, we propose a method for resolving both time and worker conflicts for a single project. We first consider how to detect a resource conflict. Then, we define an adjacency matrix to resolve the detected conflicts. Using the proposed method, we confirm that the resource conflict can be resolved through a numerical example.

This study examined the effects of household head’s worker status change type on household income and household head’s income using a total combined sample of 2,578 households from Korea surveyed in 1998 and 2002 KLIPS(Korean Labor and Income Panel Study). Binary logit regression results showed that household incomes were likely to decrease significantly when household head’s changed worker status from a regular employee, a temporary employee or a daily worker, or an employer or a self-employed to no job status, or from a regular employee to a temporary employee or a daily worker, an employer or a self-employed, or from an employer or a self-employed to a regular employee compared to a regular employee status maintenance. In contrast, household head’s incomes were likely to increase significantly when household head’s changed worker status from a temporary to a regular employee compared to a regular employee status maintenance. Women household heads were significantly associated with the likelihood of the decrease of household head’s income compared to men household heads. Household heads beyond their forties were significantly associated with the likelihood of the decrease of household head’s income compared to household heads in their thirties age-group counterparts. Household heads with education level beyond high school graduation were significantly associated with the likelihood of the increase of household head’s income compared to household heads with the education level of high school graduation. This study shows that a more comprehesive labor policy is needed for achieving sustainable household income inflow.

The Asian honeybee, Apis cerana, is a native honeybee species in Korea which is important in agriculture for pollination and honey production. For better understanding of the physiology of A. cerana, high-throughput Illumina transcriptome sequencing was performed to analyze the gene expression profiles of queen, worker, and larva. A total of 219,799,682 clean reads corresponding to 22.2 Gb of nucleotide sequences was obtained from the whole body total RNA samples. The Apis mellifera reference mRNA sequence database was used to measure the gene expression level with Bowtie2 and eXpress software, and the Illumina short reads were then mapped to 11,459 out of 11,736 A. mellifera reference genes. Total of 9,221 genes with FPKM value greater than 5 of each sample group were subjected to eggNOG with BLASTX for gene ontology analysis. The differential gene expression between queen and worker, and worker and larva were analyzed to screen the overexpressed genes in each sample group. In the queen and worker sample group, total of 1,766 genes were differentially expressed with 887 and 879 genes overexpressed over two folds in queen and worker, respectively. In the worker and larva sample group, total of 1,410 genes were differentially expressed with 1,009 and 401 genes overexpressed over two folds in worker and larva, respectively.

외국인 노동자들은 90년대 들어 그 수가 급격히 증가하였고, 각종 제조업이나 3D업종에서 중요한 위치를 차지하게 되었다. 이번에 새로 도입된 `고용허가제`는 그 동안의 국내 외국인력 정책을 그 근본에서부터 바꾼 것이라는데 그 의의를 찾을 수 있다. 외국인 근로자와 고용허가제의 정보를 바탕으로 공용허가제가 건설현장에 미칠 영향요소에 대해 설문조사를 실시하였다. 도출된 현장관리자들의 인식을 통해 향후 건설업체에서의 부작용을 제거하여 외국인 근로자 활용에 필요한 연구 방향을 제시할 것이다.

The purpose of this study is to investigate the relationship between interpersonal stress and job burnout, turnover intention of social welfare worker's in social welfare center and efficient response of welfare worker's. In order to accomplish this study purpose, the interpersonal stress of social welfare worker's in social welfare center as an independent variable, interpersonal stress as a dependent variable of job burnout and turnover intention, and stress coping ability as a moderating variable were selected. The causal relationship between interpersonal stress and job burnout, turnover intention and the moderating effect of stress coping ability were analyzed. As a result of the analysis, the interpersonal stress of social welfare worker's showed a significant effect on job burnout and turnover intention. Also, moderating effects of stress copying ability were significant. Based on the results of this analysis, the theoretical implications and policy implications of this study are suggested, and the directions and limitations of this study are suggested.
