The current 52-hour workweek in South Korea consists of 40 hours of regular work and 12 hours of overtime. Although the average working hours in South Korea is declining, it is still 199 hours longer than the Organisation for Economic Co-operation and Development average of 1,716 hours per year. In view to this, the South Korean government has now proposed to reform the workweek, mainly intending to increase the workweek to 69 hours when the workload is heavy. This reform, by increasing the labor intensity due to long working hours, goes against the global trend of reducing work hours for a safe and healthy working environment. Long working hours can lead to increased cerebrovascular and cardiovascular diseases, industrial accidents, mental health problems, and safety accidents due to lack of concentration. In conclusion, the Korean government's working hour reform plan can have a negative impact on workers' health, and therefore it should be thoroughly reviewed and modified.

Objectives : To investigate the fatigue subjective symptoms and VDT related risk factors in bank workers. Methods : A total of 2178 workers (62.8% male, 37.2% female) were surveyed with a self-administered and structured questionnaire consisting of 30 fatigue symptoms and other VDT related factors regarding work characteristics, work postures, work environments, personal medical histories, etc. Fatigue subjective symptoms were divided into 3 groups of 10 questions each: a dull, drowsy and exhausted feeling (Group I), a mental decline of working motivation (Group II), or a feeling of incongruity in the body and dysfunction of autonomic nervous system (Group III). Each question was weighted as 0 for 'none', 1 for 'sometimes', and 2 for 'always'. Results : Mean age was $35.8{\pm}7.2$ years ($38.9{\pm}6.0$ in males, $30.6{\pm}5.8$ in females), Mean work duration was $7.7{\pm}7.1$ years ($8.4{\pm}7.4$ in males, $6.5{\pm}6.4$ in females). Mean symptom score in males was $11.0{\pm}8.1$ ($4.9{\pm}3.1$ in Group I, $3.0{\pm}3.1$ in Group II, $3.1{\pm}2.8$ in Group III) and in females was $17.5{\pm}9.5$ ($7.0{\pm}3.8$ in Group I, $4.6{\pm}3.5$ in Group II, $5.9{\pm}3.4$ in Group III). Mean scores were higher in the order of Group I>III>II. Females had significantly higher scores than males in all three groups (p<0.001). Most common symptoms complained of as 'always' or 'sometimes' were feel strained in the eyes' (85.4%) among Group I, 'find difficulty in thinking'(54.2%) among Group II, and 'feel stiff in the shoulders (72.3%) among Group III. In multiple regression analysis, female, non-straight spine at workstation, more VDT work hours, history of physical therapy, glare of screen, overtime work, young age, and non-horizontal elbow position were significantly related with high score of symptoms. Conclusions : More supportive VDT work environment and education for correct work postures for VDT workers are recommended.

Purpose : This study develop a Video Recording-Based Standardized Handoff (VRSH) program at shift change for ward nurses. Methods : The study was conducted in five medical, three surgical, and one comprehensive nursing care service wards affiliated with a secondary general hospital. In this methodological study, the VRSH program was developed between April and December, 2017. It is noted that 65 nurses who were involved in the VRSH program participated in this study. Results : In line with the modified Situation, Background, Assessment, Recommendation tool, the VRSH program consisted of three phases. In the VRSH program, the average time for handoff duration was 3-5 minutes per patient. More than 90% of the ward nurses were satisfied with the VRSH program since it benefited them by reducing overtime work and improving the performance, as well as effective communication, of nurses. The content analysis of nurses' VRSH program experience, revealed three categories and eight sub-categories. Conclusions : This study provides evidence that the VRSH program improves effective nursing performance and, the handoff communication and relationships between nurses. Future studies on large sample sizes and multiple settings are required to substantially evaluate the impact of the VRSH program on clinical outcomes.

This study focused on the a 20-year evaluation of the dynamism of critical thermal anomalies in Busan metropolitan area prompted by unusual infrastructural development and demographic growth rate. Archived Landsat thermal data derived-LST was the major input for UTFVI and hot spot analysis (Getis-Ord Gi^*). Results revealed that the surface urban heat island-affected area has gradually expanded overtime from 23.32% to 32.36%; while the critical positive thermal anomalies (level-3 hotspots) have also spatially increased from 19.88% in 2000 to 23.56% in 2020, recording a net LST difference of > 5℃ between the maximum level-3 hotspot and minimum level-3 coldspot each year. It is been observed that thermal conditions of Busan have gradually deteriorated with time, which is potentially inherent in the rate of urban expansion. Thus, this work serves as an eye-opener to powers that be, to think and act constructively towards a sustainable thermal conform for city dwellers.

PURPOSE: This study examined the actual condition of physical therapy in residential facilities for the disabled and determined the degree of job satisfaction of physical therapists. METHODS: In this study, data were collected using a structured questionnaire targeting 117 physical therapists (male: 49, female: 68) working in residential facilities for the disabled. The questionnaire consisted of 21 items, including six general characteristics, one job satisfaction, and 14 actual situation-related items. RESULTS: The job satisfaction of the physical therapists working in residential facilities for the disabled was 3.81 ± .83, which was between 'normal' and 'satisfactory'. One physical therapist worked in 91.5% of places. The physical therapy room was used only by the physical therapist, occupational therapist or speech therapist, and a nurse and other departments in 65.8%, 9.4%, and 23.1% of cases. On average, six to 10 patients per day were treated the most with 45.3%, followed by physical therapy alone at 19.7%, and work related to medical rehabilitation and other departments at 72.7%. A higher number of overtime hours and nurses resulted in lower job satisfaction. CONCLUSION: The job satisfaction of physical therapists working in residential facilities for the disabled was similar to those of physical therapists working in medical institutions, but the factors affecting the job satisfaction were different. Professionalism in physical therapy was not secured, and the relationships with colleagues were an important factor in increasing job satisfaction.

Nuclear power plant projects are being increased all over the world. The construction of nuclear power plants needs huge money and time, which makes conducting a detailed analysis of productivity through the whole process. Reinforced-concrete works productivity field data was collected for more than one year and analyzed from a nuclear-power-plant project in Korea. The productivities of formwork, rebar-work, and concrete pouring were $0.54m^2/man{\cdot}day$, $0.06ton/man{\cdot}day$, $1.98m^3/man{\cdot}day$, respectively. Moreover, it is revealed that 'Day of the Week' is a driver of the formwork activity and 'Overtime' is for all of the three. The results will be a great interest of industry personnel estimating time and cost of a new nuclear power plant.
