The purpose of this study was to investigate factory workers' knowledge of sanitation management of school foodstuffs and sanitation practices. A questionnaire that identified employees' food safety sanitation management knowledge and practices was developed based on a review of literature. Subjects consisted of 221 factory workers employed at 34 factories in the Daegu and Gyeongbuk areas. Almost half of the factory workers were 40~49 years of age (45.7%), 34.8% had 1~3 years of work experience, 62.4% of the respondents received food safety education 1~2 times a month and 75.1% of the respondents were satisfied with sanitation education. However, the total score for factory worker sanitation knowledge was low: 4.63/9. Sanitation performance was self-evaluated using a Likert 5-point scale. The total mean score for the factory workers' sanitation performance was 4.63/5. Satisfaction level and the amount of sanitation education, application of sanitation knowledge, attitude regarding sanitation management, and sanitation management performance level were significantly high among workers employed in a HACCP certification facility (p<0.05). The difficulties were found to be sanitation management and the time to deliver food to schools. To instill a sense of duty and pride among workers and to ensure that the food suppliers provide best-quality school foodstuffs safely, school dietitians and factory managers must actively educate workers in safe food handling and sanitation.

The purpose of this study was to examine whether dating affected young people's concern for their looks and their oral health state, and to motivate students to promote their oral health, as national oral health depended on students who would grow into eligible members of society in the near future. Relevant literature and data were reviewed, and a survey was conducted on residents in and around Seoul, who were in their 20s, for approximately three months from June through August 2006 to find out about their oral health status. The findings of the study were as follows: 1. Whether they were seeing someone or not was investigated, and it's found that 37.5 percent had a girl friend or boy friend, and that 6.7 percent hadn't. 2. Concerning the state of dating, 40.3 percent, the largest percentage, had been dating for less than a year, and the largest number of them that accounted for 23.6 percent had been dating one person till then, 4.0 percent were considering getting married with those whom they were seeing. The most dominant type of love was eros(romantic or ardent love; 41.7%), followed by stroge(friendly love; 33.3%), and agape(altruistic, devoted love; 12.5%). 3. As for the impact of dating on oral health status, those who were seeing someone were similar to those who weren't in toothbrushing frequency, toothbrushing time and simplified oral hygiene index. There was no significant gap between the two. 4. Concerning the influence of dating on dental-treatment experience, no statistically significant intergroup differences were found in experiences of taking dental-caries treatment, bad-breath treatment and teeth-whitening treatment. There was a statistically significant intergroup gap only in scaling experience(pE0.05). 5. Regarding the impact of dating on oral health care, 59.7 percent of those who were dating thought that it affected oral health care, and the same rate of the others who weren't stood at 38.3 percent. There was a statistically significant gap between the two(pE0.01). 6. As to the influence of general characteristics on oral hygiene index, their age and gender made no statistically significant differences to that. By occupation, however, many of the company employees were in good oral health, and many of them were in bad oral health, too. The office workers were statistically significantly different from the others in that regard(pE0.01).

The purpose of this study was to examine the image of dental hygienists. The subjects in the study were 396 patients and their caregivers who visited 14 dental hospitals and dentists' offices in and around Seoul. After a survey was conducted, the following findings were given: 1. The people investigated gave a mean of 4.0 to the image of dental hygienists. Dental hygienists rated highest in terms of looking neat and tidy(4.33), and were given the lowest marks in arbitrary job performance(3.46). 2. There appeared four different types of dental hygienist images, which made a 59.824 prediction of the image of dental hygienists in general. A typical image(4.11) was most dominant, followed by professional one(4.07), personal one(4.01) and social one(3.73). 3. The relations between the general characteristics of the respondents and their image of dental hygienists could be described as below: 1) By age, those who were in their 60s(4.12) had the best image of dental hygienists, and the teenagers(3.90) had the worst image of them. 2) By gender, the men(4.05) looked at dental hygienists more positively than the women(3.96). They had a significantly different opinion on the social image of dental hygienists according to gender(pE0.05). 3) By marital status, the married people(4.00) had a better image of dental hygienists than the unmarried ones(3.95). 4) As for the influence of the type of dental institutions, they had a more favorable image of dental hygienists in dentists' offices(4.13) than in dental hospitals(3.88). There was a broad significant difference in the way they looked at the professional and personal images of dental hygienists according to the type of dental institutions(pE0.001). 5) As to the impact of educational level, those who received community-college or higher education(4.01) had the best image of dental hygienists, and those who received middle-school or lower education(3.91) had the worst image of them. 6) By occupation, the government workers and students(4.07) had the best image of dental hygienists, and the company employees(3.90) had the worst image of them. They took a significantly different view of the social image of dental hygienists according to occupation(pE0.05). 7) Concerning the impact of the frequency of receiving dental treatment, the respondents who had received it seven times or more(4.16) had the best image of dental hygienists, and those who hadn't(3.79) the worst image of them. There was a wide significant gap according to that frequency. The way they looked at the typical, social and professional images of dental hygienists was quite different significantly according to that frequency as well(pE0.001). 8) As for the influence of whether they were accompanied by caregivers or not, the people who weren't accompanied by caregivers(3.99) had a better image of dental hygienists than those who were(3.97).

This study evaluated the concentrations of urinary metabolites of polycyclic aromatic hydrocarbons (PAHs) in industrial waste incineration workers. The effect of genetic polymorphisms of xenobiotic metabolism enzymes on urinary concentration of PAH metabolites was assessed. And, aromatic DNA adduct levels were also determined in total white blood cells. Fifty employees were recruited from a company handling industrial wastes located in Ansan, Korea: non-exposed group (n=21), exposed group (n=29). Sixteen ambient PAHs were determined by GC/MSD (NIOSH method) from personal breathing zone samples of nine subjects near incinerators. Urinary 1-hydroxypyrene glucuronide (1-OHPG), a major pyrene metabolite, was assayed by synchronous fluorescence spectroscopy after immunoaffinity purification using monoclonal antibody 8E11 (SFS/IAC). Multiplex PCR was used for genotyping for GSTMI/TI and PCR-RFLP for genotyping of CYP1A1 (MspI and Ile/Val). PAH-DNA adducts in peripheral blood WBC were measured by the nuclease P1-enhanced postlabeling assay. Smoking habit, demographic and occupational information were collected by self-administered questionnaire. The range of total ambient PAH levels were 0.00-7.00 mg/㎥ (mean 3.31). Urinary 1-OHPG levels were significantly higher in workers handling industrial wastes than in those with presumed lower exposure to PAHs (p=0.006, by Kruskal-Wallis test). There was a statistically significant dose-response increase in 1-OHPG levels with the number of cigarettes consumed per day (Pearson correlation coefficient=0.686, p<0.001). Urinary 1-OHPG levels in occupationally exposed smoking workers were highest compared with non-occupationally exposed smokers (p=0.053, by Kruskal-Wallis test). Smoking and GSTMI genotype were significant predictors for log-transformed 1-OHPG by multiple regression analysis (overall model R²=0.565, p<0.001), whereas smoking was the only significant predictor for log-transformed aromatic DNA adducts (overall model R²=0.249, p=0.201). Aromatic DNA adducts was also a significantly correlation between log transferred urinary 1-OHPG levels (pearson's correlation coefficient=0.307, p=0.04). However, the partial correlation coefficient adjusting for Age, Sex, and cigarette consumption was not significant (r=0.154, p=0.169). The significant association exists only in individuals with the GSTMI null genotype (pearsons correlation coefficient=0.516, p=0.010; partial correlation coefficient adjusting for age, sex, and cigarette consumption, r=0.363, p=0.038). Our results suggest that the significant increase in urinary 1-OHPG in the exposed workers is due to higher prevalence of smokers among them, and that the association between urinary PAH metabolites and aromatic DNA adducts in workers of industrial waste handling may be modulated by GSTMI genotype. There results remain to be confirmed in future larger studies.

Purpose: In this study, we investigated the better application of the law which is about the AED installation and more effective ways of emergency medical care system, to understand the law and to research the current condition of public facilities which belong to local governments, and to seize the aspect of safety guards who currently work in order to provide the installation of AED in the public facilities and to provide more efficient emergency medical service with the effectuation of the immunity law of the good intention of first-aid treatment. Methods: In Gwang-ju, 234 public facilities have been identified by 31 December, 2008. With the exception of the duplication, we researched 158 facilities and received the answers from 95 of them. Results: In the research, 53% of them have had internal emergency first-aid education, and 55% of them didn't have this education and a CPR education manual, and 30% of the facilities even didn't know how to connect with the manager of the company for the first-aid department. On the other hand, most of them were highly interested in CPR and AED education on the ratio of 91% and 93%. 88% of them have been trained about first-aid, 51% of them haven't been retrained, 17% have never been trained. so, the reality of emergency system at public facilities is serious. 78% of them knew they are working at public facilities, though 49% of them didn't know about AED installation. 57% of them didn't know the fact there is the immunity law related with good intentions for first-aid treatment. 63% of the facilities have security guards, and 30% of them didn't answer the questions. Also, many of them agreed to the opinion that all employees should have first-aid training. At representative survey report of participator of public-facility, emergency treatment is 61%, 16% of patients calling. Accordingly they importantly think better doing an on-site first-aid than evacuating the patient. And the rates show that 57% of them answerers tend to call Fire-Office(119) for evacuating the patients, and 28% of them EMIC(1339) for the first-aid. Conclusions: In this study, we are suggest to improve the details of the efficient operations and management after the grasp of the uninstallation, indifference, and unreliable conditions of AED. 1) Need a publicity of AED install cognition which is an emergency medical instrument at public facilities. 2) Arrangement of safety agents at facilities and concerns about them for good management from the parties concerned. 3) Need a designation of legal details according to the decision of the AED installation and the standard of the AED installation. 4) Training about first-aid of safety guards and the persons concerned in the facilities should be practiced participation with the positive and through this, first-aid treatment could be done by anyone who knows the immunity law related to medical emergency. 5) The brochures for the potential users and the results form practicing the instructions need to be improved in many ways through recording the emergency cases that have happened.

The rapid increase of Passenger cars which is caused by the discomfort of Public transit and the Preference of automobiles is the major factor of increasing traffic congestions in Seoul With the point that leading the automobilists to the Public transit can be the most important Policy to ease these traffic congestions, this study focuses on the behavioral aspects of company employees and university students and investigates factors influencing bus ridership. To be brief, by estimating bus ridership through count models, this study investigates factors which influence bus ridership and elicits Political suggestions which lead automobilists to Public transit. The Purpose in this study is the application of appropriate count data model. The count data models have been widely applied to the economic area from the middle of the 1980s and to transportation aspect mainly in the foreign countries from the latter half of the 1980s. Even though a few studies in this country employed count data model to count data. all of them were Poisson regression models without suitable tests for the importance of the model specification. In the end, as the result of statistical test, negative binomial regression model which is suitable for overdispersed data was found to be appropriate for the data of weekly bus ridership. To emphasize the importance of model specification, both of poisson regression model and negative binomial regression model were estimated and the results were compared.

This purpose of this study is to extract the perceptual types of Organizational Citizenship Behavior(OCB) conceptual domain. OCB is a employee behavior that goes above and beyond the call of duty, that is discretionary and not explicitly recognized by the employing organization's formal reward system, and that contributes to organizational effectiveness. But, as is generally known, OCB is such a fuzzy concept that many researchers have been questioning the exact conceptual domain of OCB. In this context, we try to applicate Q-methodology to find more effective way of explaining the conceptual domain of OCB. Q-sample was constructed by a thorough review on the relevant literature, and P-sample is 14 employees of an manufacturing company. In conclusion, we find three types of the conceptual domain of OCB, that is coworker-oriented, organization-orienteded, and work-orienteed type. The paper ends with suggestions for future research directions.

This study aims to provide guidelines for the activities of workplace health managers by identifying their excellent health promotion activities and motivations. For this, consent for the study was obtained from 21 workplace health managers who had worked at the same company for more than five years, and a semi-structured questionnaire was sent via email to collect and qualitatively analyze the data. As a result, 17 categories and three topics were drawn. The derived topics included a sense of reward and accomplishment as workplace health managers, difficulties encountered as workplace health managers, and how to solve the difficulties. The survey respondents answered that they feel a sense of reward and accomplishment when workers open their mind, change their daily life, express gratitude, and pioneer new fields. On the other hand, they feel difficulties with unpredictable health, changes in the organizational culture, secrecy of disease, and people who think their job is easy. As a way of overcoming such difficulties, the research subjects said that it is necessary to read the minds of workers, let them know by themselves, use existing programs, have the most difficult people on their side, and spread their achievements. The results of this study revealed that it is required for workplace health managers to develop professional skills and emphasize the importance of health management to the policy-makers and employees of their workplace by continuously reporting health management performance. In addition, they need to actively benchmark the success strategies of exemplary workplace health managers.
