Objectives: An ultra dry air environment of nearly ${\leq}2%$ RH is often required in lithium battery factories. The objective of this study is to evaluate the subjective eye, pulmonary, nose, and skin symptoms of workers exposed to ultra-low relative humidity and thionyl chloride. Methods: We recruited 274 workers using a self-reported questionnaire in March 2014. Those who worked in ultra-low relative humidity and with thionyl chloride were identified and their prevalence of symptoms was compared with that of other workers. We excluded white collar workers, researchers and other workers who were exposed to various hazard factors, and finally included 164 workers. Results: There were significant differences in the rate of self-reported eye and skin symptoms between exposure group_1 and exposure group_2. Exposure group_2 experienced more frequent eye, and skin symptoms. Multinomial logistic regression analysis for experience of dry eye symptoms and skin symptoms in exposure group_2 showed that dry eye symptoms (odds ratio [OR], 6.33, 95% confidence interval [CI], 2.19-18.24, p<0.001), and itchiness (OR, 6.45, 95% CI, 1.94-21.43, p<0.01) were the significant variables. The complaints of workers experiencing ultra-low relative humidity and thionyl chloride were high compared with other workers. Conclusion: These findings suggest that exposure to ultra-low relative humidity and thionyl chloride may be associated with more frequent eye and skin symptoms than exposure to ultra-low relative humidity alone. The current precautions to protect workers from the adverse effects of ultra-low relative humidity and thionyl chloride appear to be insufficient, indicating that additional management plans to reduce symptoms should be considered.

Objectives : To investigate the information searching behavior of health care consumers according to sociodemographic characteristics. Methods : A questionnaire survey was conducted of 1,507 persons who were selected through a multi-stage stratified area cluster sampling of the Republic of Korea, excluding the province of Jeiu-do. Personal were conducted through a door-to-door survey between 27 July and 10 August 1999. Results : 80.5% of respondents used more than one source of information and those $40\sim59$ years of age, female, a housewife or student and those who claimed a religion demonstrated more active information searching behavior. A personal informer was used significantly more in those $20\sim39$ years old, female, and those who claimed a religion. Clerical workers, those with post-secondary education and a monthly income greater than 2,000,000 won ($1500) were more actively used a public informer. Low socioeconomic status and older persons used an experimental informer when they chose a health care institution. Conclusion : Regardless of the sociodemographic characteristics, personal and experimental informers were the most useful source of information. Because appropriate information was not easy to obtain, the health care consumer was dependent upon word-of-mouth communication(personal informer) when using health care services.

본 연구는 대기업과 중소기업 사무직을 대상으로 직무스트레스 하부 요인과 조직효과성의 관계와 이를 통해 사무직 근로자의 직무스트레스 개선을 위한 관리 전략 수립에 필요한 근거자료를 제공하고자 한다. 조사내용은 개인의 일반적인 특성, 업무관련사항, 직무스트레스와 사회심리적 건강수준 및 조직효과성 평가를 위해 직무만족도, 직무몰입, 이직의도, 프 리젠티즘을 포함하였다. 모든 평가 도구의 Cronbach's α값은 0.640∼0.924로 만족할 만한 수준이였다. 자료 수집은 2014년 6월 26일~8월 1일까지 설문지 154부를 배포하였고, 150부를 최종 분석대상으로 하였다. 자료는 SPSS 23.0을 이용하여 카이 제곱 검정, t-test, ANOVA, 다중회귀분석을 실시하였다. 대기업 모델에서는 직무스트레스 하부 요인 중 보상부적절이 직무 만족도, 직무몰입, 이직의도에 통계적으로 유의한 관련성을 보였다(p<0.05). 중소기업 모델에서는 조직체계 요인이 직무만족 도, 직무몰입에 유의한 관련성을 보였으며, 특히 이직의도는 직무스트레스 하부 요인 중 조직체계, 보상부적절, 조직문화와 밀접한 관련성을 보였다(p<0.05). 사회심리적 스트레스는 대기업 모델에서는 조직효과성과 유의한 관련성을 보이지 않았으 나, 중소기업 모델에서는 프리젠티즘과 유의한 관련성을 보였다. 직무스트레스와 조직효과성의 관계는 조직특성에 따라 달 라지므로, 직무스트레스 관리 계획 수립 시 해당 조직에 필요한 스트레스 관리 영역을 확인할 필요성을 제시했다는 측면에 서 본 연구의 의의가 있다. The purpose of this study was to provide the evidence necessary to establish job stress management strategies to improve office workers conditions by looking at the impact on job stress factors depending on the nature of the organization. The stress related variables (job stress and psychological well-being) and organizational effectiveness variables (job satisfaction, job engagement, intention to leave, and presentieesm) was included. A total of 154 questionnaires were distributed from 26th June to 1 August 2014 and 150 people were analyzed. The results indicated that a lack of reward was negatively correlated with job satisfaction and job engagement, and positively correlated with the intention to leave (p<0.05) in a large-sized company model. Moreover, in a medium-sized company model, organizational injustice was statistically significant with job satisfaction and job engagement. Organizational injustice, lack of reward, and occupational climate was positively correlated with the intention to leave (p<0.05). This study has its significance in that it looked at the job stress as a predictive variable to explain the organizational effectiveness and highlights the need to establish a stress management strategy depending on the nature of the company.

Objectives : We examined the effect of sociodemographic factors, cancer, and psychiatric disorders on suicide by gender and age-specific patterns in South Korea. Methods : The study is a case-control study. Claim data was obtained from the national health insurance database and national death registration database. The number of people who committed suicide was 11,523, which was matched with a control group consisting of ten times as many people at 115,230 selected from the national health insurance and medical aids beneficiaries. The medical utilization of the case group was one year before death and that of the control group was from July 1,2003 to June 30, 2004. Four variables-address, economic status, presence of a psychiatric disease, and cancer-were used in multiple logistic regression analyses. Results : Living in cities or in rural areas showed a greater risk for suicide than living in a metropolitan city. Low economic status, the presence of a psychiatric disorder, and cancer were also statistically meaningful risk factors for suicide. The three major psychiatric diseases, schizophrenia, alcohol abuse, and bipolar disorder, were meaningful in all age groups, but the scale of the odds ratio differed by the age group. Only the psychiatric disorder variable was meaningful in the adolescent group, whereas a psychiatric disorder and economic status were meaningful for the young adult group, and all variables were meaningful for the middle-aged group. A psychiatric disorder and cancer were meaningful in the elderly group, economic status was meaningful for male subjects, and address was meaningful for female subjects. Conclusions : Factors such as living in city or rural areas, low economic status, the presence of a psychiatric disorder, and cancer were statistically meaningful risk factors in suicide. These factors also differed by age group. Therefore, policymakers should establish policies for suicide prevention that are relevant for each age group.

본 연구는 일개 대학병원 근무자 679명을 대상으로 신체 부담과 근골격계 증상이 직무 스트레스에 미치는 영향을 파악하였다. 분석 결과 직무스트레스에 영향을 미치는 관련 요인으로는 여성, 저연령층, 미혼, 교대근무자, 8시간 이상 근무자, 근무 경력이 낮은 군이 유의한 변수로 선정되었다. 직무 스트레스 수준은 비흡연(p=0.000), 운동을 하지 않는다(p=0.022) 및 비음주(p=0.038)에서 높았고 통계적으로도 유의한 차이를 보였다. 또한 직무스트레스에 영향을 미치는 관련 변수로 정신적 피로, 근골격계 증상, 피로수준 및 결혼상태가 직무스트레스 위험을 증가시킬 수 있다. 결론적으로 육체적 작업부담과 직무스 트레스간의 쌍방향성 상승효과가 있음을 확인하였다. This study examined the effects of the symptoms of musculoskeletal disorder and the burden of the body on work stress in a university hospital workers. The research surveyed 679 subjects. The relevant factors affecting the job stress were found to be female, young people age group, unmarried, shift work, work more than 8 hours, short experience workers. The work stress was significantly higher in the non-smoker (p=0.000), regular exercise/sports(p=0.022) and non-drinking(p=0.038) groups. In addition, the mental fatigue, presence of musculoskeletal symptoms, fatigue level, and marital status increase the risk of the work stress. The results showed that the burden of the body and musculoskeletal disorders are related interactively with each other.

원예활동 프로그램이 제조업 사무직 종사자의 심박변이도에 미치는 영향

이정배(Jeongbae Rhie),채유미(Yoo-Mi Chae),이숙(Sook Lee) 한국원예학회 2017 원예과학기술지 Vol.35 No.6

본 연구는 제조업 사무직 종사자의 원예활동 프로그램이 심박변이도(heart rate variability, HRV)에 미치는 영향을 분석하고자 실시하였다. 자동차 제조업에 근무하는 사무직 근로자를 연구 대상으로 하여 40명을 편의 추출한 후, 실험군 15명과 대조군 25명으로 임의 배정하였다. 8회기의 원예활동 프로그램 시행 전 및 후에 실험군과 대조군을 대상으로 식물에 대한 태도 및 HRV 변화를 측정하였고, 대상자의 나이, 결혼상태, 거주형태, 직급, 월급, 근무시간, 음주, 흡연, 운동을 보정하여 다중회귀 분석을 실시하였다. 분석 결과, 식물에 대한 태도는 실험군과 대조군 간에 통계적으로 유의한 변화가 없었으나, HRV 지표 중 하나인 SDNN(standard deviation of NN interval), VLF(very low frequency) 값이 대조군에 비해서 통계적 유의하게 증가하였다. SDNN은 자율신경계에 부조화가 있을 때 감소하고, VLF값은 레닌-안지오텐신계와 관련이 있고, 스트레스 증가시 감소한다. 때문에 이런 결과는 원예활동 프로그램이 사무직 종사자의 스트레스 관리에 유용함을 의미한다. This study was conducted to analyze the effects of a horticultural activity program on heart rate variability (HRV) in white-collar workers. The subjects enrolled in the program all worked in automotive manufacturing. Forty white-collar workers were randomly selected; 15 workers were assigned to the case group and 25 workers were assigned to the control group. The workers’ attitude toward plants and their HRV was measured before and after an 8-session horticultural activity program. Multivariate regression analysis was performed, adjusting for factors such as age, marital status, house type, job grade, monthly income, work time, drinking, smoking habit, and level of exercise. There was no statistically significant change in the worker’s attitude toward plants. However, standard deviation of NN interval (SDNN), very low frequency (VLF) values of HRV in the case group were significantly increased compared to the control group. SDNN decreases when there is discordance in the autonomic nervous system, and the VLF value isrelated to the renin-angiotensin system. These values decrease with increasing stress.

Though the attending system was first implemented in 2003 to facilitate the efficient utilization of medical resources and specialties, only a few hospitals and physicians are participated in that system. The purpose of this study was to investigate the actual facts which related to operation of attending system and propose a basic information to revitalized of the attending system in Korea. The data were collected between August 1 and October 30, 2005 from 25 hospitals and 42 attending physicians who were in part of the attending system. Medical institutions were unwilling to participate despite the advantages of the attending system with respect to the utilization of medical resources and improvement in the quality of medical services. The primary reason for this was the lack of understanding among physicians about the attending system and the difficulty(lack of time) encountered by the attending physicians in administering care to patients hospitalized in the attending hospitals. Moreover insufficient reimbursement for rendered medical services constituted another important reason. In conclusion, we can state that the establishment of a committee is required to discuss the issues surrounding the attending system and to control the growing disparity between the viewpoints of hospitals and physicians. Regardless, there is a need to develop economical incentives for medical institutes. The attending system served as a useful policy in promoting the medical service system and bringing about an improvement in the management of medical institutes.

Objectives : To assess the degree of quality improvement (QI) implementation and to identify its associated factors. Methods : A mailed questionnaire survey of the QI staffs at hospitals with 400 beds or more was conducted between September 15 and October 30, 2000. Of the 108 hospitals eligible for inclusion in our study, 79 participated, yielding a response rate of 73.1%. After excluding 12 hospitals that did not perform any QI activities, 117 responses from 67 hospitals were used in our analysis. The degree of QI implementation was measured using the Malcolm Baldrige National Quality Award Criteria (MBNQAC). Factors evaluated for association with the degree of QI implementation were cultural, technical, strategic, and structural factors of the hospitals. Results : The average 01 implementation score across the 7 dimensions of MBNQAC was 3.34 on a 5-point scale, with the highest score for the area of customer satisfaction (3.88) followed by information and analysis (3.59) and quality management (3.35). The results of regression analysis showed that hospitals with a ofter information system (p<0.05) and using scientific and systematic problem solving approach (p<0.01) tended to perform a higher degree of QI implementation. While statistically insignificant, positive associations were observed for the factors of group or developmental culture, the degree of employee empowerment, and the use of prospective strategy. Conclusions : It appears that the most important factors contributing to active implementation of QI in Korean hospitals were the use of scientific skills in decision making, and having a quality information system to produce precise and valid information.

This study was performed to explore the effect of customer satisfaction and switching barriers on customer royalties in medical services. 900 households, 1% sample were randomly selected from K city located in Kangwon province. Interview survey was performed with structured questionnaire for the entire people, 923 persons who experienced medical service utilization during one year before survey on time, september, 2002. In comparison of switching barriers by sociodemographic characteristics, lower income group and lower educated group showed the higher level of recognition level on availability of changing the service provider significantly. In terms of economic loss as one of switching barriers, the group of over aged 61, the lower income group and the lower educated group felt higher than other groups. Also, the time loss of switching barrier was recognized in 41-60 aged group and employee in service industry highly. For the perceived risk factor as another switching barrier, the high educated group showed the higher recognition level in performance risk and felt higher social risk than other groups. In analysis of customer satisfaction and loyalty levels by switching barrier components, the lower level of availability of changing the service provider and the higher level of recognition for economic and time loss, they showed the higher satisfaction and loyalty levels. In final step, multiple regression analysis showed the positive relationship between customer satisfaction, switching barrier and customer loyalties. Besides, the moderating effect of switching barrier in relationship between customer satisfaction and loyalties was significant and this results suggests that the influence of customer satisfaction to customer loyalties might be weakened in high level of recognition for switching barrier. In conclusion, perceived risk of economic and time loss as switching barrier is an important factor and should be considered in planning of marketing strategy carefully in terms of defensive marketing.
