In this study, recognized building-related health symptoms of various workers in dental college hospitals are surveyed and analyzed in order to improve indoor environment at dental college hospitals. We conducted a questionnaire survey for 682 workers in three dental college hospitals located in Seoul from Sep. 20 to Oct. 8, 2004. Most workers at dental hospitals complained about noise, poor ventilation, dusty environment, and air dryness. SBS symptoms score for subjects was 1.43${\pm}$0.74 (often feel) and major symptoms was throat, CNS, eye, and nose symptoms. Recognized Building-related health symptoms are significantly related to tasks, working experience, job-satisfaction, indoor environment recognition index, medical history, used to special material, and number of dental unit chair. Also working places and ventilation are significantly related to the symptom. Based on the results, it can be said that special dental treatment causes undesirable environment such as noise, dust, and bad odor. It is also related to recognized building related health symptoms reported by workers at dental hospitals. So managemental efforts are needed to improve indoor environment which is related by dental treatment.

Objectives: An outbreak of humidifier disinfectant-related respiratory disease has not only been a massive disaster for end users, but it is also a concern for the workers of the manufacturers. This study presents the results of a questionnaire survey on the health effects among workers involved in the manufacture of humidifier disinfectants. Methods: Seven sites where humidifier disinfectants were manufactured were identified. A questionnaire survey was conducted to assess the physical symptoms experienced by workers related to humidifier disinfectants. Among a total of 177 workers, 42 subjects were available for the survey. Results: Twenty-one of the 42 respondents reported that they experienced respiratory or skin and mucosal irritation symptoms during work. Of the respondents who experienced symptoms, 14 believed that their symptoms were related to the work process and reported that the symptoms were experienced while working. However, no respondents reported ongoing symptoms or sequelae during the investigation period, and this result could not minimize selection bias due to low response rates. We then compared the characteristics of the group who experienced suspicious symptoms with those of the group without any symptoms. There was no statistically significant difference between two groups. Conclusions: We could not find significant health effects related to the humidifier disinfectant manufacturing process, although 21 respondents experienced stimulant symptoms and 14 respondents believed that the symptoms were related to the work process. Due to the long period of time after occupational exposure and the lack of data, there were many limitations to this study. However, this is one of the few follow-up investigations of workers related to this large-scale disaster in South Korea and the limitations of this study highlight the need to follow up with a nationwide database rather than an occasional survey.

Purpose: After abortion, many women could have psychologic problems and physical symptoms. But in Korea, the symptoms and psychologic problems and after abortion had rarely been researched. Methods: The subjects were 29 women who visited Kangnam Korean hospital for postabortion management from May 2007 to December 2007. From questionnaire, we researched the variable symptoms after abortion and depression as Edinburgh Postnatal Depression Scale. Results: The 79% of patients took a rest only less than 1 week after abortion. As the rest time was shorter, the number of symptoms was higher. The frequent symptoms were related to the dysfunction of autonomic nerve system and the circulating system. The patients after abortion had high Edinburgh Postnatal Depression Scale scores, the mean score was $13.33{\pm}7.11$. The high EPDS scores and the number of symptoms was related with methods of abortion and age. Conclusions: Postabortal symptoms are related with physical symptoms and depression. So psychological evaluation would be needed. And for prevention of postabortal symptoms, the adequate rest time would be demanded after abortion.

This study was conducted to evaluate the differences in symptoms of work-related musculoskeletal disorders (WMSDs) and health-related quality of life (HRQoL) between vinylhouse farmers and non-vinylhouse farmers. The study included 118 residents who lived in a rural community. All subjects were assigned to the vinylhouse farmers group (N=58) and the non-vinylhouse farmers group (N=60) according to main agricultural work type. All respondents were interviewed by means of a structured questionnaire. WMSDs symptoms were measured by a self- assessed questionnaire on symptoms of musculoskeletal disorders, and HRQoL was measured by SF-36. Vinylhouse farmers had significant more symptoms of WMSDs in each regional parts of musculoskeletal system, and had significant poor total health status in SF-36. Symptoms of WMSDs were most reliable risk factor for HRQoL. Various health promotion interventions are needed to prevent WMSDs in all farmers and especially vinylhouse workers.

Objectives : To identify whether and how Korean people understand 'qi deficiency' and related symptoms. Methods : We developed a questionnaire based on the experts' comments and modification asking understanding of 'qi deficiency' and symptoms or situations related with it. Total 128 workers at community healthcare centres across the country completed the questionnaire. They were asked if they know the meaning of the word 'qi deficiency' and to give at least three symptoms or situations that they conceive are related with 'qi deficiency'. The responses were collected and descriptive and frequency analyses were performed. Results : Approximately 79.7% of responders answered that they understand the meaning of the word 'qi deficiency' and of them, 71.6% reported that they experience 'qi deficiency' sometimes or more. Regarding somatic or condition-related responses in qi deficiency, lack of power or energy (26.6%), tiredness or fatigue (22.2%), dizziness (7.2%) or sweating (6.3%) were the most frequently reported symptoms. They related symptoms such as loss of appetite (4.3%) or easily catching colds (2.4%) with qi deficiency. Factors described in traditional pattern recognition of qi deficiency were not exactly matched with the responses from this survey. Conclusions : Korean people have rather a broad concept of qi deficiency covering a range of symptoms and this should be taken into account in developing a deficiency assessment tool.

Purpose: To determine effects of job-seeking stress on perimenstrual symptoms of female college students with health and non-health related majors and mediating effects of stress coping styles. Methods: Data were collected from 189 female college students who were juniors or seniors. This study was conducted using questionnaires on job-seeking stress, perimenstrual symptoms, and stress coping styles. Data analysis included descriptive statistics, Pearson correlation analysis, and multiple regression analysis using SPSS, version 23.0. Mediation analysis was performed according to the Baron and Kenny method and Sobel test. Results: Job-seeking stress was significantly and positively correlated with perimenstrual symptoms in non-health college students. Passive stress coping styles demonstrated a complete mediating effect on the relationship between job-seeking stress and perimenstrual symptoms of those with non-health related majors (${\beta}=0.31$, p=.002). Such effect was significant (Sobel test; Z=2.06, p=.039). Conclusion: Effects of job-seeking stress on perimenstrual symptoms were mediated by passive stress coping styles of non-health related major students. Based on findings of this study, effective stress cope strategies should be developed considering characteristics of majors to manage perimenstrual symptoms of female college students with high job-seeking stress.

Traffic-related environmental factors (TREF) are a major problem in developed countries, leading to increased atopic sensitivity, allergy symptoms, and diseases. This study shows an association between traffic-related pollutants, distance of road and gas station from the children's daycare center, and allergy symptoms. Data was obtained from the 2018 survey, an ongoing allergic diseases prevalence survey for children aged 4-7 (n=1175). This survey considered 36 public daycare centers, across 6 districts in Seoul. Allergic symptoms were defined as the presence of at least 1 or more allergic diseases (International Study of Asthma and Allergies in Childhood (ISAAC)). TREF was derived from the distance to the nearest main roads and gas stations. Geographic data processing and variable computation were conducted using ArcGIS version 10.2. The odds ratios for allergy symptoms increased by 1.189 (1.235-2.679) times with decreasing distance to main roads and by 1.846 (1.176-2.896) times with decreasing distance to a gas station. This study concludes that main roads and gas-stations near children's daycare centers are related to the allergy symptoms in children.
