This study was carried out to investigate the present status of nutrition services for infants in public health centers and the need for nutrition services of health workers and infants mothers. The study subjects were 146 health workers and 197 infants mothers. The results were as follows : At present, the only major nutrition services for infants were vaccination and dental care. Proper nutrition management services were available to infants. Nutrition knowledge scores were 16.8 for health workers and 15.3 for mothers out of 20 possible points. Health workers strongly demanded a well-organized nutrition education program, government support, audio-visual materials and the employment of a community nutritionist. The public health workers, in particular, demanded the development of education programs for breastfeeding and weaning. The infants mothers demanded services of nutrition information and teaching of cooking and menu planning. Based on this, the results suggest that the employment of a community nutritionist and the development of practical nutrition service programs for infants are needed very urgently for public health centers.
The major goal of caring the elderly is not to cure the patient, but rather to improve or maintain the individual functional ability. With the aged population increases, there is increasing consensus among health care workers about the importance of developing a tool to measure and evaluate the health status of the elderly. As many writers is pointing out, care of the elderly embraces the spectrum of physical-social-psychological problems and an enormous number of variables could be introudeced into the health worker's routine measurement. But such an expansive approach to measurement could have disadvantages. The purpose of this study is to introduce the measurement tools of physical functioning, perhaps the most important measure required in long-term care, which are separated into three categories of measures; general physical health, ADL, IADL. It is important that all health workers who provide care to the elderly incorporate the concepts of functional health status into the routine assessments. And continuous study about reliability and validity is needed to apply those foreign tools to Korea.

This paper proposes a system that utilizes USN(Ubiquitous Sensor Network), Bluetooth and smart phone to improve the function of senior houses. In typical approach, a system in a senior house either directly accesses the status of elderly people by its sensor or is alerted by elderly people who trigger an emergency bell, derive a decision and take an appropriate action. In addition, it is possible for a designated social worker to check the status of senior patients through monitoring system connected by UTP(Unshielded Uwisted Pair) cables, but the responsible person has to be present to monitor patients' status. However, the new system, suggested in this paper, embed Bluetooth function in a blood pressure gauge, thus the smart phone receives patients' health information such as blood pressure through Bluebooth, if any abnormal event occurs. Consequently, the smart phone sends SMS(Short Message Service) to a responsible social worker or a designated hospital. When this program in the paper becomes a reality, an unmanned system that is able to determine suitable actions for certain events will be established, even if a social worker were absence.

This study was carried out to investigate characteristic of vinyl chloride emissioned from poly vinyl chloride extrusion process and to evaluate the efficiency of local exhaust ventilation system. Before local ventilation facility was constructed in poly vinyl chloride extrusion process, the average worker exposure to vinyl chloride was 3.15 ppm, which exceeded Threshold Limit Value of American Conference of Gorvernmental Industrial Hygienists (ACGIH-TLV), 1 ppm. lt is possible that vinyl chloride residues in the poly vinyl chloride resin was released or degased due to extrusion heat. The larger the width of vinyl tube become, the higher worker exposure to vinyl chloride was. It is estimated that vinyl chloride from vinyl chloride resin increased as amount of poly vinyl chloride resin extruded in the extrusion process increased. Canopy hood was an appropriate type for poly vinyl chloride resin extrusion process. This local exhaust ventilation has fan static pressure of 7.65 inch wg($190mmH_2O$, total volumetric flowlate of 4,796 CFM ($135.8m^3$/min) and fan power requirement of 12 hp (8.952 Kw). After this local exhaust ventilation was constructed there, the average concentration of worker exposure to vinyl chloride was reduced to be 0.46 ppm, which was below the Threshold Limit Value, 1 ppm. Also, the removal efficiency rate of vinyl chloride attained by local exhaust ventilation was 85.3%. It was a statistically significant (p<0.01).

Organizational culture has been, by and large, regarded as one of the most significant factors to manage organizations. Especially the understanding of empowerment is pivotal, leading to explain organizational cultures. For hospital workers whose services are closely related to quality and performance of their hospitals, empowerment is now called upon more than ever before. This study is intended to investigate the relationship between organizational culture types and hospital workers' empowerment levels. The data were collected from 589 hospital workers at one university hospital and two general hospitals using the self reported questionnaire from Jan.9 to Jan.20 in 2004. The findings were as follows: 1. Empowerment levels were significantly different among the four organizational culture types. Developmental culture group showed the highest empowerment score(3.74), and next were group culture(3.64), rational culture(3.62), and hierarchial culture(3.46). 2. There was a significantly positive correlation between group culture and empowerment(r=.298, p<.000), between developmental culture and empowerment(r=.295, p<.000). But there was not a significantly correlation between hierarchial culture, and between rational culture. 3. According to the multiple regression analysis, self-esteem(${\beta}$=.417, p<.001), position (${\beta}$=-.190, p<.001), self-control(${\beta}$=.185, p<.001), and age(${\beta}$=.169, p<.01) were significant among general properties for organizational empowerment. As for organizational cultures, developmental culture(${\beta}$=.165, p<.001), group culture(${\beta}$=.099, p<.01), and rational culture (${\beta}$=.063, p<.05) were significant other than hierarchial culture. In conclusion, it is necessary to promote group culture and developmental culture to enhance hospital worker's empowerment level, and this article elucidates that understanding the organizational culture embedded in each organization is important for efficient management of organization.
Purpose: This research aims to investigate into company workers' awareness of scaling and related factors and provide basic materials for setting up appropriate policies to improve the hygiene of the mouth of industrial workers and developing training programs for the worker's hygiene of their mouth, as part of researches to establish schemes for improving the workers's hygiene of their mouth. Method: Questionnaire was conducted by convenience sampling for 220 office workers belonging to H Group located in Seoul Metropolitan city over about 5 weeks between December 17, 2007 and January 20, 2008. The questionnaire for this study was constructed in consideration of general characteristics of the subjects, behaviors of the dental management. and scaling. The collected questionnaires were electronically processed using SPSS 12.0. Result: The followings are the findings of this research. First, in general, scaling is experienced by male unmarried worker in their 40s. whose monthly average income is 1.00-1.99 million won and have little interest in the hygiene of their mouth and, consequently. whose hygiene of the mouth is not good. Second, scaling is experienced once every six months by the worker in their 50s or older, who are college graduates and have much interest in the hygiene of their mouth and, consequently. whose hygiene of the mouth is good. Third. scaling is not periodically conducted because of high costs of it in terms of almost every parameter of general characteristics. Fourth, they have correct knowledge of scaling since they regard it as 'removing of plaque and tartar' in terms of every parameter of general characteristics. Fifth, the workers' sex (pE0.05), hygienic condition of the mouth (pE0.05) and knowledge of scaling (pE0.001) have a significant effect on their scaling experience. Conclusion: It is considered that dental health management should be continued by training of the importance of prevention through scaling as measure for dental health promotion of workers.

This study was conducted to evaluate worker exposure to airborne asbestos fibers by industry, and to evaluate polarized-light microscopy for determining airborne asbestos fibers. A total of 11 plants including asbestos textile, brake-lining manufacturing, slate manufacturing, and automobile maintenance shops were investigated. Rsults of the study are summarized as follows. 1. Worker exposure levels to airborne asbestos fibers were the highest in asbestos textile industry, followed by brake-lining manufacturing, slate manufacturing, and automobile maintenance shops, in order. In asbestos textile industry, large variation of asbestos levels was found by plants. The worst plant indicated airborne fiber concentrations in excess of 10 fibers/cc, however, the best plant showed concentrations within 0.50 fibers/cc. 2. Characterization of airborne fibers by industry indicated that fibers from asbestos textile industry were the longest with the largest aspect ratio. Fibers from automobile maintenance shops were the shortest with the smallest aspect ratio. Based on characteristics of fibers and the highest levels of concentrations, it is concluded that workers in the asbestos textile industry are exposed to the highest risk of producing asbestosis, lung cancer, and mesothelioma. 3. Result s obtained using polarized-light microscopy were $43.7{\pm}12.3%$ of the results obtained using phase contrast microscopy. This may be resulted from the worse resolution of polarized-light microscopy than that of phase contrast microscopy. Based on the results, it is recommended that polarized-light microscopy be used for mainly bulk sample analyses and further study be performed to improve the method for determining airborne samples. However, polarized-light microscopy can be used for determining thick fibers.
In this study, the impact of organizational culture on the quality of social work services in hospitals were empirically analysed. A mailed questionnaire survey was conducted between February 19 and April 10, 2001. A sample of total 70 hospitals, including general hospitals with one social worker at least and single-department hospital with two social workers or more, were identified nationwide through the registry of Korean Association of Medical Social Workers and Korean Association of Hospitals. According to coping strategy and reacting pattern with the environmental changes, four types of organizational culture in each hospital, classified as group culture, developmental culture, hierarchial culture, and rational culture, were adopted for the independent variables. Three dimensional aspects of quality of social work service - structure, process, and outcome were selected as dependent variables in this study. Also the quality of social work service was distributed into provider-perceiving quality and consumer-perceiving quality The major findings were as following in summary; First, most social workers reported that the characteristic of culture in their hospitals are group culture the first, hierarchial culture the second, developmental culture the third, and rational culture finally in order of comparing the level of quality perceived between social worker's recognition. Second, service provider and consumer, The provider-perceiving quality showed less score than that of consumer, especially the lowest was the score of quality of outcome perceived by provider. Third, according to the types of organizational culture, there were significantly different levels of quality in total social work services, structure dimension and process dimension. The quality of outcome dimension did not show significant differences among the type of organizational culture. Finally, the most influential variables to the quality of social work service ice proved departmental form of social work unit, leader of social work unit, and developmental culture of hospital To assure quality services, accordingly, social work unit in hospital is required to be organized as a single unit, that means to be an independent department of which qualified social worker is supposed to control the unit. It is strongly recommended to develop leadership for the leaders of social work unit.

Recently, as the WHO IARC has classified radio frequency electromagnetic fields as possibly carcinogenic (group 2B) to humans, there is increasing concern about the health effects of overexposure from electromagnetic fields. Especially, the workers are exposed to higher level of electromagnetic radiation than the general public. As a result, in Europe, the protection guidelines for the worker are developed and the exposure of the worker is strictly controlled. In this paper, the EU directive, standards and guidelines of the EMF exposure for the worker were reviewed, and the exposure assessment of EMF was performed for the arc welding. Based on that, we propose a way to introduce a national policy to protect the workers from EMF exposure in working environment.
