Background: Many studies have reported negative psychological or physical effects of emotional labor. Relationship between work-related musculoskeletal disorder and psychosocial factors has been reported. To manage organizational and psychosocial factors of musculoskeletal disorder with work place intervention among emotional laborers, the factors contributing to musculoskeletal pain must be identified and clarified. Methods: Data from the fourth Korean Working Conditions Survey was analyzed. Based on the questionnaire, we selected emotional laborers and included 3,979 participants, excluding participants whose variables were of interest to the researcher. Weight variable was applied. The association with musculoskeletal pain and psychosocial factors, such as workload, monotonous work, job control, social support, and job satisfaction, was investigated. Results: Univariate analysis demonstrated that there was a statistically significant relationship between social support, job satisfaction, and musculoskeletal pain. In multivariate analysis, job satisfaction showed a strong correlation with musculoskeletal pain at all sites. Social support was significantly associated with backache. Monotonous work seemed to reduce the pain in the neck and/or upper limbs. Job control and work intensity were not significantly associated with musculoskeletal pain. Conclusion: In this study, job satisfaction was significantly associated with musculoskeletal pain, and social support among the social psychological stressors could reduce musculoskeletal pain. However, unlike previously known, the presence of monotonous work resulted in reduced musculoskeletal pain. The results of this study will help to establish the direction of improvement of atmosphere in the workplace to prevent the musculoskeletal pain of emotional laborers.

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.

This study was conducted to understand the seasonal patterns and variation of the copepod community in the Anma Islands of Yeonggwang, Yellow Sea, with a focus on seasonal surveys to assess the factors affecting their occurrence. Throughout the survey period, Acartia hongi, Paracalanus parvus s. l., and Ditrichocorycaeus affinis were dominant species, while Acartia ohtsukai, Acartia pacifica, Bestiolina coreana, Centropages abdominalis, Labidocera rotunda, Paracalanus sp., Tortanus derjugini, Tortanus forcipatus occurred differently by season and station. As a results of cluster analysis, the copepod communities were distinguished into three distinct groups: spring-winter, summer, and autumn. The results of this study showed that the occurrence patterns of copepod species can vary depending on environmental conditions (topographic, distance from the inshore, etc.), and their spatial occurrence patterns between seasons were controlled by water temperature and prey conditions. One of the physical mechanisms that can affect the distribution of zooplankton in the Yellow Sea is the behavior of the Yellow Sea Bottom Cold Water (YSBCW), which shows remarkable seasonal fluctuations. More detailed further studies are needed for clear grounds for mainly why to many Calanus sinicus in the central region of the Yellow Sea are seasonally moving to the inshore, what strategies to seasonally maintain the population, and support the possibilities of complex factors.

This paper investigated Taxi drivers physical subjective symptoms and what factors were interviewed caused the symptoms. The 600 owning taxi-drivers in Seoul during four months from August 1st, 2003 to November 30th, 2003. 1. The average age of the owning taxi-drivers was generally quite high 54 years old. It was very high index compared with the Todai Health Index(THI) and Cornell Medical Index(CMI) of health check tables. 2. According to the age in THI health check table, the complains of mental subjective symptom by reason of age was high among 31 to 40 years old. People who belonged that age group showed high fabrication(L), digestion(C) and aggressiveness(F). The results showed the complains of mental subjective symptom. All items except tiredness(I), melancholia(N), and hypersensitivity(P) were commonly reported by people in their sixties. On the other hand, melancholia(N) and hypersensitivity(P), people in their forties were investigated highly. Statistically, the items of heartㆍblood stream(C) and digestion(D) systems were similar between the two ages, but anger(Q) was different. (p<0.05) 3. From the complains of mental and physical subjective symptoms about work satisfaction on the THI health check table, all items except eyeㆍskin trouble(B) showed strong dissatisfaction. From the complains of mental and physical subjective symptoms about work satisfaction on the CMI health check table, the items of respiratory system(B), digestion(D), nervous system(G), miscellaneous(K), inadequancy(M), and anger(Q) showed similar results. Otherwise, heartㆍblood stream(C) showed statistically different. 4. From the complains of mental and physical subjective symptoms on salary satisfaction in the THI health check table, in the case of people receiving around 1 million won, the complains of physical symptoms showed high among all items except for the respiratory(A) and digestion(C) systems. The eyeㆍskin trouble(B) item showed statistical similarity. The complains of mental and physical subjective symptoms according to a salary degree on the CMI health check table was completely different from the above results. In people received around 1~1.5million won, all items except anxiety(O) showed high. The hypersensitivity(P) item showed statistically different.

최근 전세계적으로 공장과 공단, 공업도시, 노동자 주거 단지, 쓰레기 매립지 등의 인더스트리얼 사이트를 공공의 땅으로 회복하고 공원화함에 있어 장소가 지니고 있던 역사적, 형태적 특성을 기반으로 한 고유한 장소성을 고려한 장소기억의 재현이 중요한 화두가 되고 있다. 이에 본 연구는 최근 공원설계에 있어 주요한 목표가 되고 있는 장소성 높은 공원을 조성하기 위한 기초자료로서 조성 및 개원 당시 공원을 설계하는 방식에 있어 장소의 기억을 적극적으로 끌어들였다는 공통점을 지니고 있는 서울숲과 선유도공원의 장소성 형성 구조를 도출하여, 향후 장소성을 고려한 공원계획 및 설계를 위한 시사점을 제시하고자 한다. 본 연구를 토대로 도출된 서울숲, 선유도공원에 대한 장소성 형성구조 연구결과는 다음과 같다. 첫째, 구조방정식 모형을 통하여 서울숲과 선유도공원은 자연물리적, 인공물리적, 체험적 요인의 만족도가 장소성 형성에 유의한 영향을 미치고 있음을 확인하였다. 또한 장소성이 높아질수록 방문용의성이 높아지는 것으로 나타났다. 둘째, 장소의 물리적 환경에 따라서 서울숲과 선유도공원은 놀이, 운동 등 체험적 요인이 상대적으로 중요한 것으로 나타났다. 따라서 장소성을 높이기 위하여는 물리적 요인에 더하여 체험적 요인을 중요하게 고려하여야 한다. 셋째, 동일한 유형의 장소일지라도 개별 장소의 특성에 따라 요인 및 변수의 상대적 중요도는 다르게 나타났다. 장소별 구조방정식 모형에서 확인할 수 있듯이 각 요인과 관련된 구체적 변수의 중요도는 장소에 따라서 차이가 있을 수 있다. 예를 들어, 서울숲에서는 자연물리적 요소가 인공물리적 요소보다 중요한 것으로 나타났지만, 선유도공원에서는 인공물리적 요소가 자연물리적 요소보다 더 중요한 것으로 나타났다. 본 연구는 장소성 연구에 있어 정량적 연구방법인 구조방정식 모형을 다양한 장소에 도입하여 장소성 구조모형을 도출하고, 이를 통하여 장소성 형성을 위한 보다 구체적 방안을 제시하고, 더 나아가 장소성의 실체에 한걸음 더 접근할 수 있었다는데 의의가 있다. 본 연구에서의 분석방법 및 결과를 토대로 더욱 다양한 장소를 대상으로 장소성 형성모델을 도출하는 후속 연구가 계속된다면, 의미 있고 개성적이며 정겨운 도시의 장소, 더 나아가서 인간적인 도시, 경쟁력 있는 도시를 만드는 일에 크게 기여할 것이다.

Purpose : To collect and interpret basic data involving the discomfort level of platelet donors and to see which nursing interventions would help make plateletpheresis more comfortable. Methods : Using "the Platelet Donor's Discomfort Scale" developed by the researcher herself and reviewed by an expert panel, the severity of discomfort as well as factors contributing to the development of this discomfort were analyzed. This scale contained 59 items and each item was scored by the 4-point Likert manner. Between March 1, 1996 and May 31, 1996, 500 platelet donors(16 years of age and older) were enrolled in this study. The Statistical methods used were factor analysis, t-test, and ANOVA. The results were as follows : 1. The mean of the platelet donor's discomfort scale was 130, range 69-207, possible score ranging from 59-236. 2. The platelet donor's discomfort scale had psychological, environmental, physical, and time-related factors. The time- related factor was the highest positive correlation with the development of the discomfort. 3. In looking at the psychological and environmental factors of the discomfort scores, the 16-20 age group had significantly higher ratings than those of the 26-30 age group. The students' group had higher scores than the soldier's group, and those who used the V-50, MCS -3P, or the PCS Plus machines had higher scores than those who used the COBE Spectra machine(P<.05, respectively), 4. In relation to the physical factor of the discomfort score, the youngest group felt significantly more discomfort, the student's group had a higher score than the soldier's group, and those who used the V-50, MCS-3P, or or the PCS Plus machines had higher scores than those who used the COBE Spectra machine(P<.05, respectively). 5. The time related factor of the discomfort score had the highest scores in every variable, however, statistically significant differences were not found between any of the variables(P>.05). Conclusion : Based on the above results, it can be oserved that the time-related factor was the most important factor influencing discomfort. The age and job of the donor, as well as the type of machine used, were significant variables in predicting the level of discomfort, regardless of psychological, environmental, and physical factors. This data could be used to determine nursing interventions that would relieve some of the discomfort of patients, as well as donors, undergoing plateletpheresis. Furthermore, consideration of the donor's time, introduction of a platelet donor pool system, publicity and education about platelet donation are required.

This study assumes that though buildings have identical color of the outer walls, their colors and images make the difference according to neighboring environmental factors and visual range. Based on the assumption, it carries a quantitative analysis of physical and image difference, targeting colors of the outer walls of high-rise apartment buildings within apartment complex. As a result, it is identified that the outer colors of the buildings on the streetside of high-rise residential complexes are significantly different according to neighboring environmental factors and viewers' visual range. And, it is suggested that in planning colors of outer wall, colors should be arranged in consideration of color difference according to visual range.
