  • The purpose of this study was to investigate the effects of job stress on job satisfaction according to interpersonal relationship type among school dieticians and nutrition teachers. The online survey was conducted from Oct. 26th to Nov. 7th, 2017 in 2,000 randomly selected dieticians and nutrition teachers in the capital area. A total of 453 collected questionnaires were used for analysis. SPSS v.21.0 Statistical Package Program was used for the statistical process. For the results regarding interpersonal relationship type of dieticians, open-type (73.3%) was the highest, followed by self-assertive-type (23.0%), isolated-type (2.6%), and careful-type (1.1%). Regarding overall job satisfaction, 'human relation' was the highest, followed by 'job itself', 'working environment', and 'personal rating & welfare system', in that order. According to interpersonal relationship type, in the case of 'open-type' or 'careful-type', job satisfaction was relatively high. Regarding overall job stress, 'job demand' was the highest, followed by 'lack of reward', 'organizational system', 'interpersonal conflict', 'occupational climate', 'job insecurity', and 'insufficient job control', in that order. In accordance with interpersonal relationship type, overall job stress index was high in terms of 'self-assertive-type' or 'careful-type'. For the results of analyzing the correlation between job satisfaction and job stress index, all areas showed statistically significant negative correlations. Multiple regression analysis was performed to study the effects of job stress on job satisfaction mediating interpersonal relationship type. Job stress had different effects on job satisfaction in terms of 'open-type' and 'self-assertive type'. In conclusion, different strategies are needed for dieticians with different interpersonal relationship types to improve job satisfaction and to reduce job stress.

  • Although, mercury (Hg) is not a naturally abundant element in the environment, residues frequently occur in many environmental compartments because of widespread contamination from industrial and agricultural practices. This research evaluated Hg-B concentrations of general population who was not occupationally exposed. And also evaluates the association between life factor and health effect with Hg-B concentration of general adult through interrelationship estimation and index about kidney function and oxidative damage that appeared by questionnaire survey and medical examination. Average concentration of Hg-B was 3.19 $\mu$g/L (ND$\sim$8.64 $\mu$g/L), and persons who exceed mercury exposure level (5 $\mu$g/L) presented in WHO (1990) appeared by 16 (7.0%). High-risk group (smoking and meat main intake group) had significantly higher Hg-B concentration than low-risk group (non-smoking and vegetable diet main intake group) (p < 0.05, low-risk group: 3.30 $\mu$g/L (ND$\sim$8.64 $\mu$g/L), high-risk group: 4.27 $\mu$g/L (ND$\sim$7.84 $\mu$g/L).

  • Objectives: The organizational culture of small-scale enterprises is influenced by a lack of awareness of industrial accidents and a business-oriented culture. Therefore, the purpose of this study is to establish a correlation between chemical awareness and worker safety, which is the reason why a company's safety environment is responsible for human factor accidents. Methods: The research model established the organizational culture, human relationships, organizational relationships, workplace culture, safety climate, and safety parameters, all of which affect the perception of chemical substances, then established safety rankings, communication, safety regulations, and safety support. Results: In order to derive the results of this study, the satisfaction level was mostly derived from the degree of engagement (+) depending on the number of years worked, in the hierarchical regression analysis. During work with chemicals, the number of years spent on the level of the service was determined by the influence of the chemical (-). Based on this company, the occurrence of chemical accidents caused by chemical materials was felt to be felt at the risk of causing the hazard to be felt, the absence of physical damage was excluded from the variables. The other variables detected in the variables were $62.8{\pm}24.4$. Conclusion: As a result, it is necessary to develop a statistical model for the verification of the hierarchical regression analysis, and the relationship between safety and awareness of the dangers of chemicals and biological agents requires periodic safety training. Job satisfaction was found to be higher if the level of awareness was sufficient.

  • Purpose: The purpose of this study is to analyze how the experiences of nurses influence their role model function when they are mothers of children who in turn have become nurses or nursing students. Method: The subjects of this study were 12 nurses, 8 of their children who became nurses and another 4 children then in training to become one. Data were collected through in-depth personal interviews and subsequently analyzed through a phenomenological approach. Results: Four main themes were identified as follows; 'Persuasion and dissuasion,' 'Proud but still pathetic,' 'As mom and senior nurse' and 'Great to pass it down.' Conclusion: The results of this study show that the nurse as mother could be a positive professional role model for her children. However, they tended to stress the arduous clinical routines and poor work conditions nurses currently experience. Should such routines and conditions improve, mothers who are nurses would be more willing to recommend the nursing profession to their children. Improving the professional environment is thus important because intergeneration nursing mobility provides a reliable resource to recruit qualified and dedicated nursing personnel.

  • We report the first case of summer-type hypersensitivity pneumonitis(SHP) in Korea diagnosed by positive serum antibodies to Trichosporon cutaneum. Hypersensitivity pneumonitis(HP) has been commonly classified as an occupational respiratory diseases. However, evidence that sensitizing organisms can also contaminate and cause pulmonary diseases in home environment has been increasing. One such disease is SHP. In Japan, 75% of cases with HP are SHP. Even though there has been no known SHP case in Korea yet, there has been high possibility of SHPs in Korea because our country has areas which have hot and humid summer climate similar to Japan. This first case of SHP in Korea suggests that there may be another cases in Korea and nation-wide survey may be required. We report here the first confirmed case of SHP in Korea.

  • Polycyclic aromatic hydrocarbons (PAHs) are well known for strong carcinogen. However, the human exposure analysis of PAHs is quite difficult and unreliable because of hard for estimation of actual expose dose. Then urinary 1-hydroxypyrene (1-OHP) has been a biological marker of exposure to PAHs. The purpose of this study was to investigate total amount from exposure to PAHs soused by indoor occupational exposure, and residence at Seoul metropolitan area and Kyeonggi province in Korea. Thirty-five housewives were included in this study from April 2003 through February 2004. Dietary habit and general characteristics such as age, type of building, existence of passive smoking, period of residence, fuel type for heating and ventilation type were obtained by self administered questionnaire. Urine samples were collected at morning and freeze quickly. Urinary creatinine was measured for converting into 24 hr urine. Concentration of the indoor PAHs was examined by NIOSH method number 5506. Urinary 1-OHP and PAHs were analysed by HPLC. Correlation coefficient between urinary 1-OHP levels and pyrene concentration of indoor air was 0.66 and statistically significant(P<0.01). The difference of urinary 1-OHP level due to dietary habits were not significant. Urinary 1-OHP level of Spring, Summer, Autumn, and Winter were $0.21{\pm}0.12,\;0.10{\pm}0.17,\;0.16{\pm}0.12,\;0.17{\pm}0.14{\mu}g/g$ cr, respectively. The arithmetic means of urinary 1-OHP for four season tee $0.16{\pm}0.14 {\mu}g/g$ cr. There was a trend that urinary 1-OHP level of residents who dwelling in apartment were higher compared with detached home, Comparison of 1-OHP level between heating by kerosene and LPG, Much higher gas heating type than kerosene type (P<0.05). This result implies that the urinary 1-OHP can be applied as the PAHs exposure indices.

  • In order to maintain the continual safety management in a company, it needs to evaluate and monitor its implementation of safety management. Because the number of major-accidents is not an effective method of indicating company's safety performance, various efforts to develop more reasonable indicators have been made in world wide. After Korean government has legally required the PSM report, PSM compliance audit has been developed and made by the authorities concerned since 2005. However, this audit consists of complicate procedures difficult to utilize as companies' own audit program and corresponds to only a conformity check that confirms whether the PSM be operated and maintained properly. So a new index by which to measure easily the level of safety performance and self-monitor the implementation of safety management is needed. We have studied a new method that may quantitatively evaluate the performance of safety management by investigating application cases in foreign countries and doing the domestic survey of lots of companies subject to PSM regulation in Korea. This study proposes three of safety performance indices(SPI) together with the several prerequisite preconditions and the timing for application of each index. Although the first draft of SPI needs further legal support, it might help to evaluate every company's safety level. The second draft of SPI is a voluntarily evaluating method based on web-site online program. The last draft of SPI consists of a series of simple questions about 12 elements of PSM. Also each of 3 indices has differences in evaluation methodology and application area and, therefore, they may be used concurrently.
