A comparative study of the dental health perception and dental health behaviors among 12,325 middle and high school students in urban and rural areas was conducted by using "2010 National Dental Health Investigation". The results of this study are as follows. For the dental health perception and the utilization of dental service, all middle and high school students had a low perception of the their dental health status toward the farming and fishing regions from the urban. For the time of tooth-brushing among the dental health behaviors, most middle and high school students brushed their teeth after lunch. In connection with the frequency of cariogenic snack intake, high school students had a greater percentage toward the farming and fishing regions from the urban. For the dental health status, middle school students in big cities had a high average of carious permanent teeth, but high school students had a high average of carious permanent teeth toward the farming and fishing regions from the urban. In other words, there was no significant difference in missing permanent teeth, filling permanent teeth and decay permanent teeth between middle school students by region, but high school students had a greater percentage of the dental health perception and dental health behaviors toward the farming and fishing regions from the urban, showing a little difference. Consequently, there was a relationship between middle and high school students' perception of dental health and their behaviors of dental health.

Purpose: The number of people using the internet to meet their health information needs is growing. However, little is known about the characteristics of the senior internet health information seeker. The purpose of this study was to identify the socio-demographic and health-related characteristics, as well as the internet health information seeking behaviors and attitudes in the elderly. Method: Data was collected from 385 elderly subjects(aged 55 years or older) and living in Seoul and Gyeonggi. We used questionnaires developed by researchers in this study. Data was analyzed using the following methods: descriptive statistics, t-test, $X^2$-test and Fisher's exact test. All statistical tests were performed using the SAS version 9.13. Results: The elderly using the internet to seek health information had relatively good subjective health and were living with a spouse. In general, the purpose of internet use was to search for information, and mainly used at home. The search in the disease management area was higher than the frequency of searches for health promotion. The elderly showed a generally positive attitude regarding health information. Conclusion: It is needed to increase the use of the Internet for finding health information and promote accessibility for internet health information in the elderly.

These experiments were conducted to determine the effects of Gamdutang on the accumulation of cadmium in the body of groups of rats that received an 8-week administration of 1.7, 3.4 and $6.8{\mu}g$/g/day of cadmium, respectively, while the other groups of rats received an 8-week administration of a mixture of cadmium by concentration and Gamdutang. A comparative analysis of these groups was conducted in respect of weight, accumulated cadmium in blood and diverse organs and pathological findings from the kidneys. As for the cadmium accumulation in blood, livers, kidneys, and testis, with the lengthening of the experiment period, the cadmium and Gamdutang mixture-administered groups tended to have reduced accumulation levels compared with the groups exclusively administered cadmium. Histopathological observation of the kidneys, observed in the cadmium exclusively administered groups showed hemorrhagic necrosis in glomeruli, swelling of tubules, epithelial shedding and necrosis of tubules; however, only mild tissue lesions were observed in the cadmium and Gamdutang mixture-administered groups. Given the above results, Gamdutang is deemed to have the effects of reducing the accumulation of cadmium in blood, liver, and testis when low-concentration cadmium is administered to rats.

Recent criticisms of the conduct and use of risk assessment by regulatory agencies have led to a wide range of proposed remedies, including changes in regulatory statutes and the development of new methods for assessing risk. The mandate to this Committee was more limited. Our objective was to examine whether alterations in institutional arrangements or procedures, particularly the organizational separation of risk assessment from regulatory decision-making and the use of uniform guidelines for inferring risk from available scientific information, can improve federal risk assessment activities. Before undertaking to determine whether organizational and procedural reforms could improve the performance and use of risk assessment in the federal government, the Committee examined the state of risk assessment and the regulatory environment in which it is performed. In this chapter, we define risk assessment and differentiate it from other elements in the regulatory process, analyze the types of judgments made in risk assessment, and examine its current government context. Because one chronic health hazard, cancer, was highlighted in the Committee's congressional mandate and has dominated public concern about public health risks in recent years, most of our report focuses on it. Furthermore, because activities in four agencies--the Environmental Protection Agency (EPA), the Food and Drug Administration (FDA), the Occupational Safety and Health Administration (OSHA), and the Consumer Product Safety Commission (CPSC)--have given rise to many of the proposals for changes in risk assessment practices, our review focuses on these four agencies. The conclusions of this report, although directed primarily at risk assessment of potential carcinogens as performed by these four agencies, may be applicable to other federal programs to reduce health risks.

Objectives : The aim of this study was to investigate the degree of awareness of the national cancer screening program by the Korean public and define its relationship with cancer screening intention. Methods : The study collected data by conducting an online survey from April 19 to 24, 2016, and received a total 354 responses. Additionally, we performed frequency analysis, chi-square test, and logistic regression analysis. Results : Based on the results for the degree of awareness for the national cancer screening program, 151 (42.7%) people were aware of the program, while 203 (57.3%) were not aware the program. From the chi-square test and logistic regression analysis, marital status and awareness of the national cancer screening program were found to have a statistically significant influence on screening intention. Conclusions : An increase in the screening rate should be established with a systematic promotion plan for the national cancer screening program.

Objectives: The purpose of the study was to examine the expected role and competency of future public health dental hygienist. Methods: This study was cross-sectional design. One dental hygienist per 16 cities and provinces was selected from the list of Korea Society of public dental hygienists. After signing in the informed consent, the interview was carried out. Transcripts were made after each interview. Six researchers recorded meaningful contents in the transcripts. They classified and integrated the information that they had recorded commonly or not. Their opinions were converged by conference. Two supervisors verified results whether they were derived from actual recordings for the reliability of the results. The records were confirmed once again and corrected into common message. Results: The main difficult subjects in public health official examination were public health, English, and medical legislation to pass the examine. The preliminary certificates included public health related certificate, computer certificate, and driver's license. In the personality aspect, creativity, activeness, cooperation and good responsibility were very important trait to public health official. Among 16 interviews, 9 were positive and 5 were negative about the future prospects of a public dental hygienist. Conclusions: The future of public health dental hygienist will be positive. Throughout effort to prepare for the public health official, the public health dental hygienist will be expanded and in many ways the dental hygienists will take the charge of the important parts of the public health administration in the near future.

Objectives : To investigate the changing pattern of medical utilization claims following the economic crisis in Korea. Methods : The original data consisted of the claims of the 'Medical insurance program of self-employees' between 1997 and 1998. The data was selected by medical treatment day ranging between 8 January and 30 June. Medical utilizations were calculated each year by the frequency of claims, visit days for outpatients, length of stay for inpatients, total days of medication, and the sum of expenses. Results : The length of stay as an inpatient in 1998 was decreased 4.7 percent in comparison to 1997. However, inpatient expenses in 1998 increased 10.8 percent as compared to 1997. Inpatient hospital claims in 1998 increased 6.2 percent over 1997, although general hospital inpatient claims in 1998 decreased 3.3 percent in comparison to 1997. The outpatient claim frequency decreased 7.3 in 1998 percent as compared to 1997 Outpatient visit days of in 1998 were decreased 8.5 percent in comparison to that recorded in 1997. Outpatient claim frequencies of 'gu region' in 1998 decreased 10.5 percent comparison to that in 1997, but 'city and gun region' decreased less than 'gu region'. Conclusions : Medical utilization in 1998 deceased in relation to 1997 Medical utilization by outpatients decreased more than that of inpatients. Medical utilization by 'gu region' decreased mere than the other regions.

A study was investigated the effects of the probiotic mixture (PM) contained Lactobacillus plantarum (L. plantarum) SY-99 $2.4{\times}10^9CFU/kg$ and Bacillus subtilis (B. subtilis) SJ-61 $2.2{\times}10^9CFU/kg$ on growth performance and fecal microflora counts of broiler chickens. Referred to the previous studies, a total of 160 one-day-old male broiler chicken (Ross 308) were randomly assigned to four experimental groups, which were a basal diet alone (control) and supplemented with PM 0.1 g/kg feed (T1), PM 0.2 g/kg feed (T2), and PM 0.4 g/kg feed (T3). After 28 days of administration, the average daily feed intake of T1 and T3 was significantly different compared to that of control (p<0.05). In addition, the feed conversion ratio of T2 and T3 was significantly improved compared to that of control (p<0.05). On the 28th day after administration, all treatment groups were significantly increased fecal lactic acid bacteria (LAB) counts and decreased fecal Enterobacteriaceae (ENT) counts compared to T1 (p<0.05). The results of this study indicated that the combination of L. plantarum and B. subtilis strains in the range of 0.2-0.4 g/kg feed could be used for the improvement of growth performance and fecal microflora in broiler chickens.
