In this study, a smart jack-up system was developed to prevent safety accidents by performing risk analysis when a structure is lifted for maintenance. A quantitative risk analysis program that can analyze the risk using the pairwise comparison matrix analysis method was developed. The risk was analyzed in real-time for the lifting structure by connecting the program with an automatic jack-up system. Displacements were measured by the IR sensor among the components of the automatic jack-up system, and the displacements were provided to the quantitative risk analysis program. To confirm the performance of the smart automatic jack-up system, experiments were conducted on bridge and risk analysis was performed when a superstructure was lifted. A linear variable differential transformer (LVDT) was also installed on the bridge to verify the performance of the smart automatic jack-up system. The maximum displacements were measured using the devices, and the declinations were compared. The performance of the simultaneous operation of the jack-up device was verified by the analysis of variance (ANOVA).

최근 체형에 대한 인식의 변화로 국내에서는 체중조절이 사회적인 문제로 다루어질 만큼 커다란 관심의 대상이 되고 있으며, 체중조절을 시도하는 사람들도 급속히 증가하고 있다. 이에 저열량식단과 특수영양식품 등을 이용한 다양한 형태의 비만관리프로그램과 영양교육프로그램이 등장하면서 이들 프로그램의 체중감량효과에 대한 연구가 활발하게 진행되어져 오고 있다. (중략)

The purpose of this study is to verify the mediating effects of job insecurity on the relationship between COVID-19 risk perception and mental health in hotel workers. For this study, a sample of 633 hotel workers completed the questionnaires: COVID-19 risk perception, job insecurity, depression, anxiety, somatic symptoms. The data was analyzed by SPSS 25.0 program and PROCESS macro program. The main results can be summarized as follows. 1. The risk group of the job insecurity had a significantly higher level of mental health(depression, anxiety, somatic symptoms) compared with the normal group. 2. COVID-19 risk perception showed a significant effects on job insecurity and mental health(depression, anxiety, somatic symptoms). 3. The results showed a partial mediating effects of job insecurity on the relationship between COVID-19 risk perception and mental health(depression, anxiety, somatic symptoms). On the basis of the results, we discuss that hotel workers have the vulnerability of mental health in disaster situations such as COVID-19 pandemic, and that mental health risk increases due to the job insecurity caused by COVID-19. we propose the need to support human resource management measures and psychological programs for hotel workers.

에너지분야 국가핵심기반시설에서 산업재해 및 업무중단 사고예방을 위해 재해경감활동관리체계(BCMS)에서 일일위험지수 재난안전관리 프로그램을 자체개발 운용하여 정부의 중대재해 감축 로드맵의 핵심적인 4대 전략 중 하나인 사업장에서 유해위험요인에 대한 자기규율적인 예방관리체계의 확립한 사례를 제시하였다. 이에 대한 신뢰성 검증을 위해 중대산업재해 감축효과에 영향을 미친 사업장의 BCMS, 일일위험지수 및 중대재해처벌법 간의 관계성을 연구한 결과, 제도 간 개념의 관련성이 높으며, 상호 보완적이고 영향을 미치는 것으로 확인되었다. 따라서 동종 사업장에서 재해경감활동관리체제의 일일위험지수를 활용한다면 중대재해예방관리에 도움이 될 것으로 기대된다.

Purpose: This study was done to identify the effects of a health diary program on fall related outcomes the low-income elderly women. Methods: The study was carried out with a nonequivalent control group with pretest-posttest design. The study was composed of two groups, each made up of 24 subjects: experimental group and control group. The subjects were low-income women aged over 65 years with osteoarthritis and both the experimental and control groups were made up of subjects with the same age profiles. The independent variable was the health diary program, and the dependent variables were fall related outcomes (fear of falling, fall-efficacy, knowledge of fall) difficulty of performing activity, and mood state. The health diary program was performed for 50 minutes each session and twice a week for 8 weeks. Data were collected before the health diary program 10 weeks after the beginning of the program. Results: The experimental group showed significant differences in knowledge of fall, fear of falling, and mood state compared to the control group. However there was no significant differences in difficulty of performing activity and fall efficacy. Conclusion: The results of this study may be used as part of an education to prevent falls for low-income elderly women with osteoarthritis.
