There, is increasing evidence suggesting that passive smoking increases the risk of lung cancer and other disease. though the potential health effects of exposure to environmental tobacco smoke (ETS) is a controversial subject. Since smoking in restaurant is prevalent in Korea. The concern on passive smoking exposure of non smoking service workers has been. requested. ETS exposure of non smoking service workers at restaurant was assessed because they have spent their times in restaurant indoors. The purpose of this study was feasibility of nitrogen dioxide(NO_(2))as exposure marker of ETS. The results of the study were as follows: 1. Average NO_(2), concentrations in indoor and outdoor at restaurants were 57.01ppb(±12.4) and 54.29ppb(±9.54), respectively. Comparing office-workers, service-workers at restaurants were exposured highly. 2. The personal NO_(2) measurement as exposure marker of ETS could cause The exposure error because NO_(2) can he generated by combustion appliances in indoor. 3. Service-workers spent their most time (86.6%) in indoor. Mean time spent at restaurant indoors and at home was 9.4 hours and 10.9 hours. respectively. 4. Personal NO_(2) levels correlated with indoor NO_(2) concentrations of restaurant (r=0.70) and of their home (r= 0.52) rather than of outdoor NO_(2) concentration of restaurant (r=0.35). The causes of personal NO_(2) exposure of non-smoking service-workers were considered as smoking of guests and combustion appliance indoors. 5. Personal NO_(2) exposures were estimated using Monte-Carlo simulation and time-weighted model. Estimated personal NO_(2) level was 47.2ppb (±8.3).

신원식,이경은 한국사회보장학회 2005 사회보장연구 Vol.21 No.1

이 연구는 현장 사회복지사들의 주관적 정체성의 유형과 특징을 규명하였다. 연구 방법은 인간의 주관성을 객관적으로 분석하는 Q 방법론을 사용하여 경상북도 사회복지시설 및 기관의 사회복지사 26명을 대상으로 분석하였다. 자료분석 결과, 현장사회복지사들의 정체성은 5가지로 유형화될 수 있었다. 첫째, 사회복지 현실을 수용하는 현실지향적 성향을 나타내지만 개선의 의지가 미약한 현실적 직업주의형이다. 둘째, 전문성 지향에 대한 의지가 약하고 조직의 변화, 세금부담의 증가에 거부감을 표명하는 보수적 소극주의형이다. 셋째, 사회복지 현실에 대해 만족하고, 실천현장의 개혁적인 변화나 전문성 향상에 소극적인 보수적 실용주의형이다. 넷째, 소속시설 및 기관보다는 클라이언트의 권익을 우선시하지만, 전문직으로서의 기술 개발 및 서비스 전달역할에 대해서는 중요성을 부여하지 않는 진보적 자원봉사형이다. 다섯째, 소속 사회복지기관의 부당한 요구에 대항하고, 자신이 소속된 기관이 사회복지 발전에 기여하지 못하고 있다고 인식하는 진보적 전문주의형이다. 이들은 사회복지의 대폭적인 확대를 주장하고 그에 따른 실천의지도 강한 유형이다. 이러한 본 연구의 결과는 현장 사회복지사들의 주관적 정체성을 유형화함으로써 보수교육이나 연수 프로그램, 특히 사회복지실천 영역별 세미나 등의 방향 및 세부 커리클럼을 설정하는데 기본적인 자료로 활용될 수 있다. The present study was undertaken to analyze the types and characteristics of the subjective identity of social workers. The study subjects were 26 social workers serving in social welfare agencies in the Gyungbook province, Korea and Q methodology analysis was employed for a quantitative measurement of subjective data. We categorized the identity of social workers into 5 different types. First, they are satisfied with the current trend of social welfare but devoid of an willingness to improve it. Second, they are less willing to have expertise in their working and are reluctant to accept changes such as changes organization system or changes in tax rates. Third, they accept the current status of social welfare service but less willing to change and improve the status considerably. Fourth, they put much emphasis on clients problems and work more for them compared to working for their social welfare agency itself. But they are less willing to have expertise to give social welfare service. Fifth, they are experts to try to expand the social welfare service as well as to correct obscure welfare system. Moreover they think that the current social welfare service do not meet the needs of clients fully. Accordingly, we may utilize the data of the present study 1) for analyzing the subjective identity of social workers, 2) for making adequate continuing education programs for them including specific curriculum for each type of subjective identity.

A compliant mechanism is a mechanism that produces its motion by the flexibility of some or all of its members when the input forces are applied. Whereas the topology optimization based on homogenization and SIMP parameterization has been successfully applied for compliant mechanism design, an ESO approach has not been considered yet for the optimization of these types of systems. This work presents a modified version of the evolutionary structural optimization (ESO) Procedure for its application in topology optimization of compliant mechanisms, It will be shown that an additive version of this method must be adopted in order to achieve the optimum design, since the traditional ESO method's element removal technique is not efficient in this case. The methodology is based on a mutual energy concept for formulation of flexibility and the ESO method. A multi-objective optimization problem is formulated as an application of compliant mechanism design. The procedure has tested in several numerical applications and benchmark examples to illustrate and validate the approach.
