The effects of job stress factors on psychological job stress and job satisfaction levels of school dietitians were evaluated. Questionnaires were distributed to 163 elementary school foodservice dietitians in the Seoul and Incheon area. Statistical data analysis was completed using the SPSS program. The highest stress factor was the importance of the job followed by role ambiguity, autonomy and identity, communication and participation. When dealing with job stress, the subjects showed improved and positive behaviors when communicating and participating with each other. The analysis of the relationships between job stress factors and job satisfaction revealed that the importance of the job had a negative effect on jog satisfaction. while role conflict and overload, personal relationships, and experience accumulation had positive effects. Ample occupational experience and background had highly positive effects on school dietitians' job satisfaction level whereas negative results were shown concerning circulated appointments(p<0.01). Based on these results, we suggest that role conflict and overload should be reduced in order to lower job stress levels and enhance job satisfaction levels.

Background: In this study, the measurement of job stress of electric overhead traveling crane operators and quantification of the effects of operator and workplace characteristics on job stress were assessed. Methods: Job stress was measured on five subscales: employee empowerment, role overload, role ambiguity, rule violation, and job hazard. The characteristics of the operators that were studied were age, experience, body weight, and body height. The workplace characteristics considered were hours of exposure, cabin type, cabin feature, and crane height. The proposed methodology included administration of a questionnaire survey to 76 electric overhead traveling crane operators followed by analysis using analysis of variance and a classification and regression tree. Results: The key findings were: (1) the five subscales can be used to measure job stress; (2) employee empowerment was the most significant factor followed by the role overload; (3) workplace characteristics contributed more towards job stress than operator's characteristics; and (4) of the workplace characteristics, crane height was the major contributor. Conclusion: The issues related to crane height and cabin feature can be fixed by providing engineering or foolproof solutions than relying on interventions related to the demographic factors.

As the modern society is called the narcissistic society, the narcissism is widespread in the personality of individuals and the society at large. In consideration of this side, this study explored for several characteristics of the narcissistic personality and the job stress, and explored for the relationships between the two things theoretically. The narcissism is an attempt to repair self-esteem weakened by the splitting anxiety, the lack and the pathological fusion of self-structure. The job stress is a factor that a characteristic of the job influenced on the behavioral and affective response of the person on the job directly or indirectly. This study selected organizational justices, organizational constraints, role conflict, role ambiguity, role overload, organizational climate, interpersonal relations and career development as factors of the job stress. This study viewed that the stress is made from an interaction between environmental stimulus and personal particular reaction by defining the stress as an interaction model of stimulus-response and personal reaction is caused by psychological adjustment process, personal differences. On this occasion, this study discussed that the narcissistic personality is easy to get stress and weak in the job stress with regarding the personality as a mediation variation of psychological process. As a result, the narcissists estimated themselves positively and their self-esteem is high, but they excessively showed a self biased cognitive and affective response about the negative feedback to protect themselves. Moreover, this positive estimate on themselves and high self-esteem was vulnerable and weak in the self threat. In this view, the narcissistic personality is easy to get more job stress such as organizational justices, organizational constraints, role conflict, role ambiguity, role overload, organizational climate, interpersonal relations and career development.

Excess manganese (Mn) is neurotoxic. Increased manganese stores in the brain are associated with a number of behavioral problems, including motor dysfunction, memory loss and psychiatric disorders. We previously showed that the transport and neurotoxicity of manganese after intranasal instillation of the metal are altered in Hfe-deficient mice, a mouse model of the iron overload disorder hereditary hemochromatosis (HH). However, it is not fully understood whether loss of Hfe function modifies Mn neurotoxicity after ingestion. To investigate the role of Hfe in oral Mn toxicity, we exposed Hfe-knockout ($Hfe^{-/-}$) and their control wild-type ($Hfe^{+/+}$) mice to $MnCl_2$ in drinking water (5 mg/mL) for 5 weeks. Motor coordination and spatial memory capacity were determined by the rotarod test and the Barnes maze test, respectively. Brain and liver metal levels were analyzed by inductively coupled plasma mass spectrometry. Compared with the water-drinking group, mice drinking Mn significantly increased Mn concentrations in the liver and brain of both genotypes. Mn exposure decreased iron levels in the liver, but not in the brain. Neither Mn nor Hfe deficiency altered tissue concentrations of copper or zinc. The rotarod test showed that Mn exposure decreased motor skills in $Hfe^{+/+}$ mice, but not in $Hfe^{-/-}$ mice (p = 0.023). In the Barns maze test, latency to find the target hole was not altered in Mn-exposed $Hfe^{+/+}$ compared with water-drinking $Hfe^{+/+}$ mice. However, Mn-exposed $Hfe^{-/-}$ mice spent more time to find the target hole than Mn-drinking $Hfe^{+/+}$ mice (p = 0.028). These data indicate that loss of Hfe function impairs spatial memory upon Mn exposure in drinking water. Our results suggest that individuals with hemochromatosis could be more vulnerable to memory deficits induced by Mn ingestion from our environment. The pathophysiological role of HFE in manganese neurotoxicity should be carefully examined in patients with HFE-associated hemochromatosis and other iron overload disorders.

The purpose of this study is to find options which reduce the job stress and to enhance morale through a variable analysis, and also apply this data in the legal and administration fields. The data for the research was obtained from 217 dental hygienists working in the dental clinics, dental hospitals and university's dental hospitals' in Seoul. The tool used by this study was a Questionnaire measuring on-the-job stress of dental hygienists, was a modified and revised. The Questionnaire version used to measure bank's job stress and used to suggest options by Dae-ha Yoon(1991). Classification of items for measuring job stress was based on Theoretical Study on Job Stress by Dae-hyon Song(1986). The scale used in study was the two points (yes or no in the job stress) scale measuring for variables. The period of data collection was 30 days from December 4, 1995 to January 5, 1996. The methods of data collection were self-writing, direct visit, and postal Questionnaire answering, 224 copies of Questionnaire data were collected, but only 217 copies were used. 7 copies could not be analyzed, were not used for this study. The data analysis was conducted by SPSS after coding the collected raw data. The general characteristics was obtained from real digits and percentages. In order to analyze the difference of sub-variables against the job stress based on general characteristics. Mean, Standard Deviation, and F test (ANDVA) were conducted. The following were the results of job stress variables: 1. Meaningful variable affecting the working organization, is compensation system(p〈0.03). 2. Meaningful variable affecting the working period, is work overload(p〈0.02). 3. Meaningful variable affecting average patients per day, is the career management and payment(p〈0.04, p〈0.01). 4. Meaningful variable affecting number of staff, is the comrade relationship, role conflict among patients, work overload, and job overload(p〈0.000, p〈0.05, p〈0.04, p〈0.01). The comrade relationship is most affected to the number of staffs aides. 5. Meaningful variables affecting job diversion, are the desire and value, the non-role play, and the environment(p〈0.003, p〈0.02, p〈0.005).
