Objectives: This study was conducted to evaluate asbestos handling history of workers at automobile manufacturing plants in Korea. Methods: National regulations on asbestos and Korea Occupational Safety and Health Agency(KOSHA) database on the information of asbestos containing products were reviewed. We investigated asbestos related materials from one automobile manufacturing plant. Material safety data sheets(MSDS) collected in 2010, work environment monitoring results reported from 2000 to 2013, trade union reports and asbestos survey reports were reviewed. We also interviewed workers with long career and did walk-through survey. Results: The Ministry of Labor in Korea has permitted asbestos manufacturing since 1990. In 1997, the use of crocidolite and amosite asbestos were banned. In 2007, the Korean government announced a total ban on the manufacturing, importation and use of all kinds of asbestos, which took full effect in 2009. A total of 174 asbestos products information from KOSHA database was analyzed. Extruded cement panel for building, special brake for crane farm machinery, gasket, joint sheet and thermal insulator were produced until 2007. From automobile manufacturing plant survey, we confirmed that asbestos containing materials(ACM) such as gasket, heating induction materials have been used until 2011. Asbestos containing building materials(ACBM) such as bamlites, slate and ceiling tex were reported at 122 asbestos dismantling projects in 2014. Conclusion: Although the use of all kinds of asbestos were banned from 2009, ACMs and ACBMs installed before 2009 were still found at automobile manufacturing plant until 2011 and 2014 respectively. In particular, asbestos slates should be managed because most of slates had not been removed until 2014.

The increasing cross-border mobility of dental school or dental hygiene students, educators, practitioners, programs and providers takes challenges for existing national quality assurance and accreditation frameworks and bodies, as well as for the systems for recognizing foreign qualifications. The new dental hygiene accreditation system was introduced to encourage the improvement of dental hygiene programs, to ensure the quality of education and, most of all, to establish an internationally compatible system of evaluation and accreditation. The accreditation procedure takes 1 year to complete. The result of the accreditation is released after evaluation via self-study report, site visit, preliminary draft report, responses from the institution and the results from the conciliation and review committees. The result from the accreditation procedure is either 'accreditation' or 'no accreditation'. Accredited schools receive one of several statuses following the evaluation. These are next general review, interim report and interim visit or suspension. Dental healthcare quality is not improved instantaneously, but instead gradually through continuous communication within the dental field. For this accreditation system to be successful, the following are essential: the accreditation agency should adopt hygiene education accreditation; it needs to become financially independent and managed efficiently; the autonomy and regulations surrounding the system need to be balanced; the professionalism of the system is ensured; and the dental field which includes not only dental program, but also hygiene program, needs to play an active role in the operation of the system.

Purpose: The objectives of this study was to measure the outcomes of interventions on the health and social welfare of the elderly in a rural community in Korea. The project involved integrating services of one public health center with that of one social welfare agency, which were under different administrative structures. Method: A single group pretest-posttest design was used for this research. Seventy-five elderly residents living alone in a rural community participated in the study. All of them had coverage of free basic medical care and social welfare services by the government. Major activities for the intervention included: developing partnerships among community leaders/institutes; forming committees of community residents; educating care providers and volunteers; developing 8 integrated service programs and instruments; and organizing the networks. The 20-month intervention was care-managed by a public health nurse whom collaborated with social worker, and was assisted by volunteers. The t-test was utilized to analyze the outcome variables including the elder's health, social welfare and quality of life. A major limitation of this study was the lack of a control group. Results: The outcome of the intervention was shown by improved elder's health, social welfare needs, and quality of life. Integrating the services of public health centers with those of social welfare agencies is an effective way to improve the health of the elderly in the community. Conclusion: Developing community capacity with such integrated services will pay an important role in improving the health of the elderly who live alone.

농작물 재배에 있어 가장 큰 위험 요소는 날씨이므로 재배지의 장기 농업 기상정보를 얻을 수 있다면 정식과 수확 시기 등을 예측할 수 있다. 따라서 체계적인 농작업을 기획하여 관리할 수 있으며 이는 농가의 안정적인 수확으로 이어질 것으로 기대한다. 본 연구는 GloSea5와 기계학습을 이용하여 효과적인 고랭지배추의 재배를 위한 장기 농업기상정보 예측 방법을 제시하였다. GloSea5는 계절예측시스템으로 최대 240일까지의 기상을 예측한다. 심층신경망과 공간랜덤포레스트를 이용하여 장기 일 평균기온을 예측한 결과 심층신경망이 공간랜덤포레스트에 비해 장기예측성능이 우수하였다. 하지만 공간랜덤포레스트는 강원도 전역의 기온을 짧은 시간에 예측하는 장점이 있다. 공간랜덤포레스트로 분석한 결과 여름철과 해발고도가 낮은 지역의 장기 일 평균기온이 잘 예측되었다.
