Background: This study aims to analyze the job stress of dental hygienists and the factors affecting somatization and to provide basic data for effectively managing job stress and somatization of dental hygienists. Methods: In this study, the data collected from 208 dental hygienists working in Jeollabuk-do Province were analyzed. Job stress was investigated using a questionnaire with 43 questions. In addition, the degree of somatization was evaluated through a simplified psychotherapy examination (Symptom Check List-90-Revision). Results: Age, employment history, position, average monthly income, night duty execution status, and perceived health status were significantly associated with job stress (p<0.05). The job stress sub-items scores based on general characteristics showed significance in 'workload' for those working a five-day workweek and perceived health status (p<0.05). Age, average monthly income, and perceived health status were noted in 'role conflict as a professional'. In 'lack of expertise and skill', it was noted that age, employment history, position, income, and night clinic were implemented. In 'improper treatment and interpersonal issues', level of education and perceived health status were significant (p<0.05). The higher the job stress, the higher the somatization symptom score (p<0.05), and the higher the job stress component, the higher the somatization symptom score (p<0.01). Conclusion: The job stress of dental hygienists should be reduced, and the symptoms of somatization should be mitigated. To improve the quality of medical services and the work efficiency of dental hygienists, proper treatment and compensation systems should be implemented for them to take pride as professional. Further, programs and regulations on mitigating job stress and somatization symptoms should be developed.

Background: This study aimed to investigate the association between lead exposure and serum gamma-glutamyl transpeptidase (γGT) levels as an oxidative stress marker in male steelworkers. Methods: Data were collected during the annual health examination of workers in 2020. A total of 1,654 steelworkers were selected, and the variables for adjustment included the workers' general characteristics, lifestyle, and occupational characteristics. The association between the blood lead level (BLL) and serum γGT level was investigated by multiple linear and logistic regression analyses. The BLL and serum γGT values that were transformed into natural logarithms were used in multiple linear regression analysis, and the tertile of BLL was used in logistic regression analysis. Results: The geometric mean of the participants' BLLs and serum γGT level was 1.36 ㎍/dL and 27.72 IU/L, respectively. Their BLLs differed depending on age, body mass index (BMI), smoking status, drinking status, shift work, and working period, while their serum γGT levels differed depending on age, BMI, smoking status, drinking status, physical activity, and working period. In multiple linear regression analysis, the difference in models 1, 2, and 3 was significant, obtaining 0.326, 0.176, and 0.172 (all: p < 0.001), respectively. In the multiple linear regression analysis stratified according to drinking status, BMI, and age, BLLs were positively associated with serum γGT levels. Regarding the logistic regression analysis, the odds ratio of the third BLL tertile in models 1, 2, and 3 (for having an elevated serum γGT level within the first tertile reference) was 2.74, 1.83, and 1.81, respectively. Conclusions: BLL was positively associated with serum γGT levels in male steelworkers even at low lead concentrations (< 5 ㎍/dL).

Objectives: This study examines the occurrence of disease resulting from low back pain and factors of working environment meaningfully influencing the occurrence of lumbago as well as analyzes '2nd Korean Working Condition Survey (KWCS)' conducted in 2010 so as to establish the prevention and improvement measures. Methods: The analysis method is that it is to compare the prevalence rate of low back pain according to working environment via odds ratio and to implement the test about the factors having the difference in working environment between low back pain group and normal group through weighted t-test. Results: As a result, it indicates that there is a meaningful difference for prevalence rate of low back pain according to age, status in employment and education level which are socio-demographical factors. The analysis in working hours shows that the period of work is a factor raising the prevalence rate of low back pain rather than weekly working hours. The analysis in the work risk factor indicates that the increase in prevalence rate of low back pain takes place to either workers with repetitive movement and continuously standing posture or those with heavy stress and emotional labour. Conclusions: Workers with low back pain have suffered from accident, depression, anxiety disorder and sleep. The factors in which the prevalence rate of low back pain decrease are to provide information on health and safety and working speed, and enough rest.

Health Education is very important not only in school or community fields but also in industrial fields. And health education is most fundamental and enthusiastic area in industrial health. The purpose of this study was to analyze the workers' health education needs and the factors which could affect them. The subjects for this study was 855 workers selected from 57 factories in Inchon. The results were as follows: 1. For demographic variables, sex, age, educational level, and income of the workers were investigated. Most of the workers were males (80.2%). Of the respondents, 30∼39 years old were 41.3%. Approximately 62% of the workers were high school graduates. In additions, those who reported they earned 500,000∼800,000 won monthly were 41.9%. 2. Behavioral characteristics of the workers investigated in this study included smoking, drinking and physical activities. Of the respondents, 55.9% were smoking cigarettes, and 26.8% of the workers reported they drank alcohol once or twice a week. The workers who were taking any form of exercise regularly were 31.6%. 3. Occupational characteristics of the workers included working period working hours a day, medical examination, and so on. About 37.6% of the workers had worked 1∼5 years and 53.6% of the respondents were working less than 8 hours a day. More than half of the workers in this study were taking special medical examination(59.3%) and 59.6% of the respondents were working at the production line in the factories. And most of the respondents (69.0%) were mere members of the staffs. 4. For perceived health status of the respondents, 41.1% answered they were healthy. And for the level of health status, health grade 20.4% of the workers were unhealthy. 5. Health education areas the workers in this study wanted to learn were as follows: 1) Mental health 2) Worksite environment 3) Safety control 4) Disease contol. 6. Those who reported having ever received health education in the factories were 20.9%. 7. Women had more health education needs in personal health care, disease control and family health areas than men. Each age group had different health education needs in all health areas and the differences were significant statistically. 8. The workers who had received special medical examination had more health education needs in worksite environment, safety control, and disease control areas than those who had received general medical examination. The lower the satisfaction of the work and the working environment was, the higher the health education needs of worksite environment area were. 9. For the levels of health status healthy workers were more likely than unhealthy workers to have health education needs in all health areas.

이 연구는 남성들의 은퇴가 활발히 일어나는 연령층 부부들의 식사 및 관련 행위를 분석하고 있다. 이 연구는 가사노동을 다루어 온 많은 연구들과 중첩되는 측면이 있으나, 식사준비, 식사행위, 설거지 등의 개별항목을 끼니별로 접근함으로써 일상적인 삶의 구체적인 모습에 한걸음 더 다가가고 있다. 한편, 대부분의 기존연구와는 달리 개인의 특성과 함께 부부나 배우자의 특성을 함께 고려하여 분석을 시도하고 있다. 한국통계청이 실시한 2004년도 생활시간조사자료 중 40대 후반부터 60대 후반 사이의 기혼여성들과 그 배우자들의 식생활행위를 분석해 본 결과, 부부의 식사행위, 식사준비 및 설거지 양상 등은 무엇보다도 부부의 취업형태에 따라 큰 차이를 보인다. 부부의 취업형태를 중심으로 볼 때, 부부가 함께 식사하는 비율이 가장 낮은 것은 부인만 취업한 상태이다. 은퇴연령층에서 부인만 취업하고 있다는 것은 이들이 식당 등과 같은 서비스업에 종사할 가능성이 높으며, 이로 인해 부부가 함께 식사할 수 있는 기회가 적음을 의미한다. 한편, 부인만 식사준비 하는 비율은 부인만 취업한 경우가 다른 경우보다 낮게 나타난다. 그럼에도 불구하고 부인만 취업한 경우에도 부인만 식사를 준비하는 사례가 절반 정도에 이른다. 부인만 설거지를 하는 비율 또한 식사준비를 하는 비율의 패턴과 유사하다. 이 비율 또한 부인만 취업한 경우에 가장 낮지만, 상당 수준에 이른다. 이를 통해 볼 때 식사준비와 설거지를 하는 해당 연령층 부인들의 비율은 취업상태에 따라 분명한 차이를 보이지만 대체로 이들 행위들은 여성들의 몫으로 남겨져 있다. 이는 다시 가족 내 식사준비와 설거지 등과 같은 일상적인 삶의 행위가 가족내 성역할을 반영하고 있음을 보여준다.

The purpose of this study was to investigate nutritional knowledge, practice of eating behavior guidelines, and problematic dietary habits in working high school students in comparison with non-working high school students. A survey questionnaire was formulated to obtain information on demographic variables, body size, part-time jobs, nutritional knowledge, practice of eating behavior guidelines, and dietary habits. The developed questionnaire was given out to 515 students attending a vocational high school in Yongin, Gyeonggi-Do. Those who had been working 5 hours or more per day for at least a month at the time of survey administration were defined as working students for this study. Proportions of working students were similar between male and female students (i.e. 49.5% for male, 50.5% for female). No significant difference was found in scores of nutritional knowledge between working ($8.43{\pm}2.29$) and non-working students ($8.60{\pm}2.19$). However, some dietary habits were found to be dependent on working status. While approximately 43% of non-working students reported skipping a meal, about 57% of working students did so (p<0.01). The proportion of students with any drinking experience was significantly higher among working students (92%) compared to non-working students (80%) (p<0.001). Working students were found to drink alcoholic beverages more often than non-working students (p<0.001). The mean score of practice of eating behavior guidelines was lower in working students than non-working students. The magnitude of this difference was modest ($51.33{\pm}0.63$ in working students, $53.40{\pm}0.51$ in non-working students), but reached statistical significance (p<0.01). Based on the findings from this study, it is suggested that specific behavior-oriented messages to improve certain problematic dietary habits need to be directed toward working high school students.
