Objectives: This study aimed to assess the concentration of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS) in blood and factors controlling their exposure among Koreans. Methods: Study subjects were selected to include 718 members of the general population residing in five metropolitan cities and the Gangwon Province area from August 2008 to January 2009. A questionnaire was administered to investigate lifestyle, socio-demographic characteristics, and other related factors. Blood samples were collected and extracted using solid-phase extraction and anion-exchange methods, and quantified by high-performance liquid chromatograph (HPLC, Agilent 1200 Series) coupled with a Triple Quad LC-MS/MS system (Agilent 6410). Results: Geometric mean concentrations of PFOA and PFOS in the blood were measured as 1.82 and 6.06 ng/ml, respectively. Mean PFOA and PFOS concentrations generally increased with age in both genders. Blood PFOA concentration was significantly different according to such variables as age, family income, residential district, and province. Blood PFOS concentration was significantly different by such variables as gender, age, lifestyle factors such as regular exercise, alcohol consumption, and smoking status. Also, family income, hazardous facilities, job classification, and province contributed significantly to differences in blood PFOS concentration levels. Conclusions: Blood PFOA and PFOS concentrations in Koreans were similar with those found in Japan, the USA, and Germany, but less than those in Australia. PFOA and PFOS exposure seems to be affected by a variety of factors in Korea. Therefore, investigation is required for each factor to assess the relative contribution of different variables.

Purpose - Recently on-the-job training (OJT) has become the most preferred training and development method with the emergence of the concept that workplace is the best place where learning take place. But many researchers argue that OJT is not helpful for the performance of organization because OJT is not systematic and mostly depend on quality of trainer. Since Jacobs & McGriffin introduced S-OJT (structured OJT), there has been plenty of researches. But most of the researches have focused mainly on employee's attitude and organizational performance caused by S-OJT and neglected a holistic approach of S-OJT as a system. S-OJT need to be analyzed comprehensively to understand training performance because S-OJT is operated as a system consist of input, process, and organizational context. Although S-OJT may create unintended consequences, there were few researches to explore them. Thus, the purpose of this study is to identify the critical success factors for S-OJT and to find unintended consequences of it. Research design, data and methodology - We conducted a case study on M business unit of A company which developed and has been implementing S-OJT program for years. We designed and prepared the process, collected and analyzed data for the study. We set the theoretical framework to analyze the case after reviewing theories and previous studies on S-OJT. We collected and analyzed internal reports and interview results of the employees of the M business unit. We tried to collect as many information as possible to secure the validity of the research results. Results - The critical success factors identified in the study are as follow. First, it is important to select and train proper trainers for S-OJT. Second, it is needed to develop structured training module. Third, organization have to use effective communication system like on-line community. Forth, trainer should have proper skills for training such as facilitating skill, coaching skill, and delivering skill etc. Fifth, proper learning place is needed. Sixth, organizational support is important especially, immediate supervisor support and concern is critical. Eleventh, it is needed to consider situational contexts. Among them, overload to the trainer will affect the effectiveness of S-OJT. In this study, we found an additional unintended consequence. "To teach is the best way to learn." Experience as a trainer give employee an opportunity to organize one's knowledge and skill and to attain facilitation skill, coaching skill, and relation skill. Thus, organization may use S-OJT to train the potential talent. Conclusions - Many organizations introduced S-OJT to train the newcomers because S-OJT drew attention as an important tool to develop employees. Following this trend, there has been increasing number of researches to find the results of S-OJT and identify the determinants of S-OJT success. However, most of the researches concentrated on finding effects of some factors neglecting holistic approach. This study tried to identify critical success factors affecting effectiveness of S-OJT by using case study and find additional unintended consequence. The results of the study will be useful for organizations which have a plan to adopt S-OJT.

For the study, the survey questionnaires were distributed to all 269 health centers and 138(51.3%) of them were collected. Eight of the collected were inadequate for the analysis and 130 of 269 questionnaires were finally chosen for the study. The SPSS/PC WIN 8.0 was used for the statistical analysis. The results are as follows. First, 91 out of 130 sample health centers(70%) are providing oriental medical care services. The results show that the willingness of the directors and the public awareness in community are the most important factors to provide oriental medical care services in health centers. In contrast, the lack of cooperative efforts between western and oriental medical doctors and the lack of government supports are considered as factors that intervene the oriental medical care services in health centers. About 80% of the sample health centers respond that the government supports is needed for oriental medical care services in health centers. Second, it was asked to the directors of 39 health centers which do not provide oriental medical care services regarding their future plan to include the services. About 70% of health centers respond that no plan is available now. They acknowledge that the demand on the services is the most important factor to consider the oriental services as their future medical services. Third, 69.2% of the oriental medical doctors in health centers are public health doctor. 95.6% of the sample health centers have space for the oriental medical care services in their facilities and some health centers provide the services through the private clinics nearby facilities. Finally, the surveyors consider both budgetary constraints and difficulty in recruiting doctors as barriers for the effective oriental medical care services in health centers. Finally, t-test and LSD were employed to find out the difference among several groups. The analysis shows statistically significant difference among groups about their recognition on health care policy, health care system, and effectiveness of oriental medical care services. To be conclude, the study shows the necessity of oriental medical care services in health centers. To do so, the government supports, cooperative efforts between oriental and western medical doctors, and providing job security for doctors should proceed to provide effective oriental medical care services in health centers.

In order to obtain baseline data for the development of an educational program on breastfeeding, a survey was carried out to investigate infant feeding practices, the characteristics the subjects have in common, and the factors that influence the feeding methods among women in Seoul and the Chungbuk area. Subjects included 671 lactating mothers who visited public health centers or pediatric clinics between December 1999 and February 2000, and were interviewed using a questionnaire. The results were as follows : With respect to feeding methods, the incidence of breastfeeding, formula feeding, mixed feeding and formula feeding switched from breastfeeding was 20.6%, 29.8%, 11.6%, and 38.0%, respectively. With respect to the characteristics the subjects had in common, the incidence of women who planned their infants' feeding methods before pregnancy, during pregancy, and after delivery was 48.7%, 31.0％, and 20.3%, respectively. The incidence of women who started breastfeeding in the hospital after delivery was 38.8％. About seventy seven percet of the subjects had not previously attended an educational program on breastfeeding, and most of these wanted to participate in the future in an educational program to learn about breastfeeding. Some of the topics they were interested in were“Nutritional Management for Sufficient Breast Milk”(60.3%),“Breast Care”(25.0%), and“Correct Nursing Positions”(9.8%). Most (88.2%) of the women who breastfeed suffered from physical discomforts including discomfort of the waist, and legs and discomfort due to cracked or sore nipples. “Insufficient breast milk”was the main reason for breastfeeding cessation or for switching to formula feeding. With respect to formula feeding practices, the main reasons for selecting a specific brand of formula were“the same brand the hospital used after delivery”(34.3%) and“an advertised brand”(23.3%). The strongest factor for promoting breastfeeding was“the support of husband or parents”, next were “breastfeeding in the hospital after delivery”and“planning to breastfeed before pregnancy”in that order. The characteristics the subjects had in common relating to formula feeding were“mother's job”,“high economic level”,“Caesarian section”and “planning to breastfeed after delivery”. In conclusion, it is recommended that breastfeeding be pro-moted, and educational programs be developed and offered as soon as possible to each group which had unfavorable attitudes toward breastfeeding. In addition, the monitoring and supervision of formula advertisements is required to protect consumers from the adverse effects of exaggerated advertising.

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).
