Recently, in Korea the birthrate is declining and the average life span has been increasing. Thus, compared to the previous periods nowadays, older people are required to work. Even elderly people are rejoining the workforce. Korean companies set the retirement age between 55 and 60 years of age, however, accidents occur frequently. Thus, it becomes necessary to evaluate the ability of the elderly person. Since the required function of the worker varies from job to job the evaluation of the capability must also be conducted according to the desired functions. One of the methods used in this study is the continuous control knob to evaluate the tracking control ability to investigate the relationship of manual dexterity and age. The result of the study Indicates that the manual dexterity decreases with age. However, there are differences among individuals. The individuals lifestyle affected the manual dexterity of that individual. As a result, a company may use the manual dexterity as an measure to evaluate the elderly persons work ability.

본 연구는 한국노동연구원의 사업체패널조사 1-5차년도 자료와 행정자료인 "고용보험 DB"를 결합하여 구축한 "사업체-근로자 연계자료"를 활용하여 사업체 근로자의 연령구성과 생산성 및 인건비와의 관계를 실증분석 하였다. 사업체의 생산성은 1인당 부가가치로, 인건비는 1인당 노동비용으로, 사업체 근로자의 고령화 정도는 근로자의 연령구성으로 측정하였으며 동적패널모형을 활용하였다. 분석 결과, 생산성과 인건비 모두 사업체의 35-39세 연령대 근로자의 비율을 중심으로 역U자의 모습을 보였다. 즉, 35-39세 연령대 근로자 대신 더 젊은층의 근로자 혹은 더 고령층의 근로자 비중이 증가하는 경우 생산성 및 인건비에 부(-)의 영향을 미치는 것으로 나타났다. 특히, 35-39세 연령대 근로자 대신 50세 이상 연령대 근로자가 증가할 때의 생산성 추정계수와 인건비 추정계수와의 차이가 30세 미만 연령대 근로자가 증가할 때의 생산성 및 인건비의 추정계수와의 차이보다 더 큰 것으로 나타났다. 이러한 분석 결과를 통해 고령근로자의 생산성 저하에 대한 기업의 우려는 타당하나, 동시에 기업은 이미 인건비 조정 등의 방법을 통해 고령근로자를 효율적으로 활용해 왔음도 확인할 수 있다.

The statistics of industrial accident reported by ministry of Employment and Labor denoted a significant increase of musculoskeletal disorders(MSDs) after 1993, and showed the higher incident rate by 71.3% over the overall worker's disorders. Also, it was expected that Korean society will become the post-aged society in 2026 with 20.8% of elderly who is over 65 years old. The reports suggest possible problems caused by the older worker known to have reduced working ability than the young counterparts. On this basis, the goal of this study was to investigate the relationship between MSDs symptoms and work ability in the shipbuilding industry. To achieve this goal, this study distributed a questionnaire for total 1,244 shipbuilding employers, and used 910 employers' reports which revealed validity for this study. The questionnaire included the MSDs symptoms report developed by the Korean Occupational Safety and Health Association(KOSHA) and the work ability index(WAI) developed by Finnish Institute of Occupational Health(FIOH). Results showed no relationship between MSDs symptoms and age, years of work and exercise. Also, the work ability was increased until 44 years old, but it was decreased after that time because of the reduced physical capacity. Meanwhile, the years of work and exercise have positive correlation with work ability. However, the results revealed significant relationships between WAI and age, years of work, task characteristics and exercise. All together, the MSDs symptoms have a close relationship with the work ability in that the work ability of workers with the MSDs symptoms was reduced. This study may suggest the needs of more efforts and attention on the MSDs prevention to increase the work ability.

Purpose : Delegating authority to employees exerts a positive effect on the efficient operation and service of a company. In particular, investigating how the delegation of authority granted to social workers, who have a greater workload compared with those of other occupations, influences job satisfaction and commitment to the organization is meaningful. Therefore, this study aims to investigate the impact of the empowerment of social workers on job satisfaction and organizational commitment. Methods : Toward this end, surveys were distributed to social workers employed at social welfare facilities in Daegu metropolitan city. Prior to the study, the researcher visited the institutions in which the social workers were working, explained the content in person, and conducted the self-administered survey accompanied by two research assistants who received prior training. Out of the 233 collected responses, those with unreliable responses and missing data were excluded, which left a sample of 224 for analysis. Data were analyzed using SPSS 18.0. Results : First, social workers who were older, had higher positions, and with longer years of service exhibited higher levels of empowerment in terms of differences in empowerment according to general characteristics. Second, for job satisfaction and organizational commitment according to general characteristics, the longer the period of employment, the higher the level of job satisfaction. Third, empowerment exerted an effect on job satisfaction and organizational commitment, and a positive correlation was found. Conclusion : The empowerment of social workers exerted a positive effect on job satisfaction and organizational commitment. Therefore, to improve service quality and the efficient operation of social welfare organizations in this practice, improving the empowerment of social workers is necessary by providing appropriate treatments, improving working environments, and providing appropriate discretion and decision-making authorities that are considered necessary for work performance.

This study aims to analyze the effects of job satisfaction on turnover intention among the nurses in geriatric hospitals. In terms of study methods, this study developed structured questionnaires, and distributed them to nurses working in 11 geriatric hospitals in metropolitan area. A total of 418 questionnaires (response rate: 87.0%) were used for final analysis. We conducted multiple regression analyses to analyze the influence of job satisfaction on turnover intention, adjusting for the characteristics of the research subjects. The results of this study are as follows. First, both job satisfaction and turnover intention were statistically significantly related to individual and hospital characteristics. Second, turnover intention was lower in older age group, and higher in smaller hospitals. As job satisfaction increases, turnover intention decreases. Third, the results of the regression analysis adjusting for subject's characteristics and job satisfaction's sub-categories show that the turnover intention is lower in nurses who are older, day worker, and work in bigger hospitals. Fourth, the result of subgroup analysis by hospital volume show that both of two groups are influenced by hospital ownership and satisfaction about compensation. In addition, professionalism had a significant effect on decreasing turnover intention in smaller hospitals. However, there was no statistically significant relationship between job satisfaction's sub-categories and turnover intention in larger hospitals. The results of this study confirms that job satisfaction lowers turnover intention among nurses in geriatric hospitals. It is suggested that the administrators of those hospitals continue to monitor critical factors associated with job satisfaction, and thus, reduce turnover intention, which helps improve quality of services.

Purpose: Construction sites are currently facing a socialization problem as the incidence of thermal disease-related disasters increases due to summer heat waves, exacerbated by factors like the concentration of middle-aged and older workers and global warming. The reason why construction sites are particularly vulnerable to heat waves is that there are many outdoor work, which is the peculiarity of the construction industry, and most of the construction workers are elderly. This study analyzes disaster statistics of workers at construction sites for five years to investigate the occurrence of thermal diseases and analyze factors through disaster cases to provide basic data for future disasters to be reduced. Research design, data, and methodology: According to the Construction Workers' Mutual Aid Association, as of June, more than 60% of the construction workers working in the field were in their 50s and 60s. More than 24% are in their 60s and older. Thermal diseases caused by heat waves occur when exposed to high heat or strong sunlight for a long time, accompanied by headaches and dizziness. The problem is that many elderly people have underlying diseases, so if they lose consciousness, they cannot easily recover and are likely to die. Results: According to industrial accident statistics, 182 people were injured by heat-related diseases in the summer from 2016 to 2021, of which 29 died. In particular, in the construction industry, which has a lot of outdoor work, 87 people were injured and 20 people died. Conclusions: In order to prevent heat diseases caused by outdoor work, it is emphasized that exposure time is controlled, and sufficient rest and hydration are essential. Rest, water, and shade are in line with the three principles.

Purpose : This study aimed to demonstrate the effects of visiting cognitive activities using brain training on cognition, subjective memory complaints and depression among elderly participants residing in community living in Gwangmyeong city. Methods : Over a 14-month period (October 2022 to December 2023), four brain training instructors visited the homes of older adults and conducted the intervention using a brain training kit. The participants included 32 elderly individuals aged 65 years and older, who were living in Gwangmyeong city. The assessments were conducted by an occupational therapist, a nurse and a social worker at the Gwangmyeong dementia relief center. These assessments included the following the subjective memory complaints questionnaire (SMCQ), short geriatric depression scale-Korean (SGDS-K), a cognitive impairment screening test (CIST), the consortium to establish a registry for Alzheimer's disease-Korean (CERAD-K). The participants were divided into three groups (A: 20-30 points, B: 10-19 points, C: 1-9 points) based on the CIST score. For data analysis, descriptive statistics and wilcoxon signed-rank test were performed using SPSS 24.0, and the statistical level was at a=.05. Results : The results of the intervention showed that the SMCQ score of group A improved significantly (p<.05), the CIST score of group B also improved significantly (p<.05). However, the SGDS-K score of group C improved, but did not demonstrate statistical significance (p=.080). Conclusion : The visiting cognitive activities using brain training produced significant effects on cognition, depression, and subjective memory disorders, depending on the cognitive level of the elderly participants. In the future, it will be necessary to demonstrate the effects according to cognitive level in various aspects with more elderly people.
