Due to the steady growth of the online shopping market and contact-free consumption, the volume of parcels in South Korea continues to increase. However, there is a lack of manpower for delivery workers to handle the growing parcel volume, leading to frequent accidents related to delivery work. As a result, the government and local authorities strive to enhance last-mile logistics efficiency. As one of these measures, unmanned parcel storage lockers are installed and utilized to handle last-mile deliveries. However, the existing parcel storage involves the inconvenience of couriers having to put each parcel in each locker, and this is somewhat insufficient to relieve the workload of delivery workers. In this study, we propose parcel storage devices that use active loading technology to minimize the workload of delivery workers, extract operation risk factors to apply this system to actual sites, and establish risk reduction methods based on the ALARP concept. Through this study, we have laid the groundwork for improving the safety of the system by identifying and proposing mitigation measures for the risk factors associated with the proposed parcel storage devices utilizing active loading technology. When applied in practical settings in the future, this foundation will contribute to the development of a more efficient and secure system. By applying the ALARP concept, a systems engineering technique used in this research, to the development and maintenance of storage devices leveraging active loading technology, it is thought to make the development process more systematic and structured. Furthermore, through the risk management of the proposed system, it is anticipated that a systematic approach to quality management can be employed to minimize defects and provide a stable system. This is expected to be more useful than the existing unmanned parcel storage devices.

Background: The present study aimed to analyze several aspects of the working conditions and health status of platform workers in the Republic of Korea, such as ergonomic and emotional hazards. We also compared the health status of the platform workers with that of the general population. Methods: A total of 1,000 platform workers participated in this survey from August 7 to August 17, 2022. The participants included 400 designated drivers, 400 food-delivery drivers, and 200 housekeeping managers. A face-to-face survey with a structured questionnaire was conducted by researchers who had received specific instructions. The focus of the survey extended to the work environment, encompassing factors such as workplace violence, as well as physical, chemical, and ergonomic hazards. Health-related data for the previous year were also collected, covering a range of issues such as hearing problems, skin problems, musculoskeletal symptoms, headaches, injuries, mental health issues, and digestive problems. Subsequently, we compared the health symptom data of the responders with those of the general population in the Republic of Korea. Results: Platform workers, including designated drivers, food-delivery drivers, and housekeeping managers, existed in the blind spot of social insurance, facing frequent exposure to physical and chemical hazards, ergonomic risk factors, and direct or indirect violence. The prevalence of health problems, including musculoskeletal symptoms, general fatigue, and depressive symptoms, in each occupational group was statistically higher than that in the general population after standardization for age and gender. Conclusion: The results revealed unfavorable working environment and inferior occupational health of platform workers compared with those of the general population.

In the 1990s, with enacting of the laws on the family violence in Korea, agencies such as helpline 1366, counseling center and shelter for the female victims have been rapidly increasing in number. Also police and medical center have been viewed as having major responsibility for delivering services and social workers in community welfare center and public social worker have been expected play a role in community-based delivery systems for the female victims. The purpose of this study is to measure the level of the inter agency coordination and to find out the factors affecting the inter-agency coordination in family violence and to make policy implications for a better delivery system. The data were obtained from a social survey of family violence agencies, counselling center/shelter/helpline 1366, police, medical center, social workers of community center and of public sector in Seoul and Kyeongi area. The major results are as follows: 1) the level of inter-agency coordination is low, specially the referal cases of police and medical center is very poor. 2) The type of inter-agency coordination is referals and information sharing among agencies. 3) the factors affecting inter-agency coordination is agency type, wills and efforts of agency, information sharing, experience of family violence education. The current findings suggest that the delivery system to promote inter-agency coordination efforts and for police and medical center, social worker in private and public agency to respond promptly and properly would be built up.

Despite provision of drinking water as the most common method of occupational heat stress prevention, there remains confusion in hydration messaging to workers. During work site interactions in a hot and humid climate, workers commonly report being informed to consume tepid fluids to accelerate rehydration. When questioned on the evidence supporting such advice, workers typically cite that fluid absorption is delayed by ingestion of chilled beverages. Presumably, delayed absorption would be a product of fluid delivery from the gut to the intestines, otherwise known as gastric emptying. Regulation of gastric emptying is multifactorial, with gastric volume and beverage energy density the primary factors. If gastric emptying is temperature dependent, the impact of cooling is modest in both magnitude and duration (${\leq}5$ minutes) due to the warming of fluids upon ingestion, particularly where workers have elevated core temperature. Given that chilled beverages are most preferred by workers, and result in greater consumption than warm fluids during and following physical activity, the resultant increased consumption of chilled fluids would promote gastric emptying through superior gastric volume. Hence, advising workers to avoid cool/cold fluids during rehydration appears to be a misinterpretation of the research. More appropriate messaging to workers would include the thermal benefits of cool/cold fluid consumption in hot and humid conditions, thereby promoting autonomy to trial chilled beverages and determine personal preference. In doing so, temperature-based palatability would be maximized and increase the likelihood of workers maintaining or restoring hydration status during and after their work shift.

The purpose of this study is to investigate the effects of service training and arbitration support on superstore workers' work performance. The conclusion could be summarized as follows. First, as a result of Hypothesis 1 that service training and arbitration support for superstore workers would significantly affect the factor of workers' emotional labor, when surface acting of emotion and frequency of expressing emotions were the dependent variable, only arbitration support was positively correlated. When emotional diversity was the dependent variable, there was a significantly positive relationship with service training. Second, for Hypothesis 2 that service training and arbitration support for superstore workers would significantly influence the workers' job satisfaction, it was found that only organizational support was significantly positive when wage satisfaction was the dependent variable. When job satisfaction was the dependent variable, service training and arbitration support were significantly correlated positively. Third, for Hypothesis 3 that service training and arbitration support for superstore workers would significantly affect the service delivery level when service responsiveness was the dependent variable, service training and arbitration support were significantly positive. When service expertise was the dependent variable, there was also a significantly positive relationship with service training and arbitration. On the other hand, all the three independent variables-service training, organizational support, and arbitration support-showed a significantly positive relationship when the willingness and effort of service was the dependent variable.

Background: Gig workers, also known as platform workers, are independent workers who are not employed by any particular company. The number of gig economy workers has rapidly increased worldwide in the past decade. There is a dearth of occupational health studies among gig economy workers. We aimed to investigate the association between exposure to violence and job stress in gig economy workers and depressive symptoms. Methods: A total of 955 individuals (521 gig workers and 434 general workers) participated in this study and variables were measured through self-report questionnaires. Depressive symptoms were evaluated by the Patient Health Questionnaire-9 when the score was greater than or equal to 10 points. The odds ratio with 95% confidence interval was calculated using multivariable logistic regression adjusted for age, sex, working hours, education level, exposure to violence and job stress. Results: 19% of gig economy workers reported depressive symptoms, while only 11% of general workers reported the depressive symptoms. In association to depressive symptoms among gig economy workers, the mainly result of odds ratios for depressive symptoms were as follows: 1.81 for workers type, 3.53 for humiliating treatment, 2.65 for sexual harassment, 3.55 for less than three meals per day, 3.69 for feeling too tired to do housework after leaving work. Conclusions: Gig economic workers are exposed to violence and job stress in the workplace more than general workers, and the proportion of workers reporting depressive symptoms is also high. These factors are associated to depressive symptoms. Furthermore, the gig workers associated between depressive symptoms and exposure to violence, job stress.

본 연구에서는 급증하는 배송 서비스 수요에 맞춰 더 신속하고 최저 비용으로 근거리 배송을 가능하게 하는 알고리즘을 제안하고자 한다. 본 연구에서 제안하는 알고리즘에서는 배송원으로 지하철 승객을 물류 이동에 참여시킨다. 이때 승객은 이동 경로와 일치하는 배송 물류를 선택할 수 있다. 그리고 서비스 이용자의 입장에서는 현재 근처에 경로가 일치하는 배송원을 선택할 수 있다. 이때 배송원 추천은 TF-IDF&N-gram과 BERT를 결합한 텍스트 유사도 측정 방식으로 진행된다. 따라서 기존 택배 시스템과 달리 소비자-배송원 간의 man-to-man 방식으로 양방향 선택을 지원한다. 탑승 중인 승객을 물류 이동에 참여시킨다는 점에서 비용 최소화와 배송 기간 단축을 모두 보장할 수 있다. 더하여 운송 측면에서도 특별한 기술을 요하지 않으므로, 일자리 입지가 축소된 노동자들에게 경제 참여 기회를 제공할 수 있다는 점에서도 의의가 있다.
