Objectives: This study investigated quality among three herb medicine extract granules(DSGOST) which were made from different companies to check quality control of herb medicine extract granules. Methods: we selected three DSGOST extract granules which were made from different companies. And we experimented extract granules by method from K.P(Korean Pharmacopoeia), K.H.P(Korean Herbal Pharmacopoeia) of KFDA. Results: In qualitative analysis of DSGOST, we indentified Akebiae Caulis (木通), Asari Herba Cum Radix (細辛), Evodiae Fructus (吳茱萸) in three different DSGOST extract granules. In quantitative analysis of DSGOST, Medication A,B,C contained similar content of Paeoniflorin & Glycyrrhizic acid. However Medication B contains especially lowest value of Cinnamic acid & total Decursin. Conclusions: Herb medicine extract granules have different contents of ingredients although those were made by same prescription. And these differences may influence medicinal effect to patients. So we need to make system of quality control with various research of quantitative & qualitative analysis about herb medicine extract granules.

In order to investigate the daily deposition characteristics of water-soluble inorganic components in airborne deposit on the Iksan, deposition samples were collected using a deposition gauge from October 16 to November 1, 2004. Deposition samples were collected using two different sampling gauges, a dry gauge and a wet gauge, respectively. To get wet the bottom of wet gauge during the sampling period, the volume of $30{\sim}50ml$ distilled ionized water was added in a wet gauge before the beginning of each deposition sampling. Deposition samples were collected twice a day and analyzed for inorganic water-soluble anions ($Cl^-,\;{NO_3}^-,\;{SO_4}^{2-}$) and cations (${NH_4}^+,\;Na^+,\;K^+,\;Mg^{2+},\;Ca^{2+}$) using ion chromatography. Qualify control and quality assurance of analytical data were checked by the data obtained from reinjection of standard solution, Dionex cross check standard solutions, and random several deposition samples, and measured data was estimated to be reliable. Considering the deposition sample volume, the sampling time, the surface area of sampling container, and the ion concentration measured, the daily deposition amounts for measured ions were calculated in $mg/m^2$. The total daily deposition amounts of all measured ions for dry and wet gauge were $7.5{\pm}2.8$ and $17.7{\pm}4.2mg/m^2$, respectively. A significant increase in deposition amount during rainfall days was observed for both wet gauge and dry gauge, having no difference of deposition amount between in wet gauge and in dry gauge. The mean deposition of all ions measured in this study were higher in wet gauge than in dry gauge because of the surface difference of the sampling container, especially for ${NH_4}^+\;and\;{SO_4}^{2-}$. The mean deposition amounts of ${NH_4}^+\;and\;{SO_4}^{2-}$ in wet gauge were found to be about 10 times and 3 times higher than those in dry gauge, while the rest of the chemical species were equal or a little higher in wet gauge than in dry gauge. Dominant species in dry gauge were ${NO_3}^-\;and\;Ca^{2+}$, accounting for 21% and 28% of the total ion deposition, whereas those in wet gauge were ${SO_4}^{2-}\;and\;{NH_4}^+$, accounting for 19% and 41% of the total ion deposition, respectively.

As heavy rains occur more frequently due to the recent climate change, slope collapses are increasing, and damage to human life and properties is accordingly increasing every year. The most proper method to take preventive measures against slope collapses is to remove the cause after understanding the cause of slope collapse in advance, and for such, slope safety inspection is implemented for preventive purposes, to investigate the cause, and as a measure for restoration. Thus, this Research was able to reach the following conclusion after utilizing LiDAR, which obtains detailed topographic information in a short period of time with point cloud data on slopes subject to safety inspection. First, as a result of analyzing the errors after installing a check point in the subject area, the RMSE of the horizontal location error appeared to be ${\pm}2.2cm$ and the RMSE of the vertical location error appeared to be ${\pm}3.0cm$, which shows a practically satisfactory result. Second, the economic feasibility was outstanding and obtaining accurate topographic information was available. Third, an area once scanned allowed to accurately obtain an unprescribed cross-sectional diagram in a short period of time, thus, appeared to be convenient for experts to detect dangerous sections.

Objectives: The purpose of this research was to investigate incidence and related factors of the MS in a university hospital Methods: This survey was conducted from January in 1997 to March in 2008. This study is a cohort study. The baseline subjects were 529 men and 609 women without metabolic syndrome(MS) who visited the health promotion center of Chungnam National University Hospital for general health check-up. The MS was diagnosed according to the definition by the NCEP ATP III. The abdominal obesity guidelines for waist circumference applied the Korean Society for the Study of Obesity Guideline Results: The survey exhibited that baseline risk factors that mainly affect odds ratio(OR) of the MS at follow-up were sex, ages, heavy drinking, uric acid and transpeptidase(GGT) in women. Incidence of the MS was 10.6% in total cases, 18.1% in men and 4.0% in women. The risk of the MS was significantly lower in women than men(OR=0.4, 95% confidence interval(CI: 0.2-0.9), significantly higher 50-59 Ages than < 40 ages(OR=3.4, 95% CI: 1.9-6.4), significantly high in women with heavy drinkers(OR=14.3, 95% CI: 1.2-177.5), significantly high in whole, men and women with high uric acid group(whole, OR=2.6, 95% CI: 1.6-4.2. men, OR=2.1, 95% CI: 1.3-3.5. women, OR=14.2, 95% CI: 3.0-68.3) and significantly high in women with high GGT(OR=1.8, 95% CI: 2.4-12.6). Conclusion: Risk factors of incident MS were baseline sex, ages, heavy drinking in women, uric acid and GGT in women. These can be utilized as an important index to determine risk factors of incident MS and will be basic data in part of management, education, countermeasure and selection test of the MS.

People with intellectual disabilities (ID) usually have poor oral health status and are susceptive to have more caries than general populations. Even when the patients get regular dental treatment, their dental conditions are usually not good for some additional factors. In this presentation, we show dental follow-up care of two patients who have multiple caries. The first case is a 16-year-old boy who has a unilateral facial paralysis with ID. As the lack of controlling of the muscles resulted in interfering with the self-cleansing, it would be associated with a higher incidence on the affected side. Endodontic treatment and caries treatment as restoration was performed. Due to loss of posterior occlusal support on right side, we planned to recover the right posterior relationship by full coverage restorations. In second case, a 20-year-old boy has been on a long-term follow up. Caries treatment, periodontal treatment, and prosthetic treatment were performed under several times of general anesthesia. He has been treated more than 8 years and gets a regular check at 1-month intervals, however, high dental caries susceptibility has been retained. These cases present that dentists should perform more aggressive treatment and be involved in providing better maintenance of patients with intellectual disabilities with multiple caries in adolescence. In other words, it is necessary to suggest a customized preventive strategy for patients with ID.

A questionnaire survey of 568 women over the age of 30 in 11 dongs of Goryeong- gun was performed to identify the practice rate of breast self- examination and its related factors. It was found that the practice rate of breast self- examination was 28.2%, with 9.7% of those surveyed performing breast self- examinations more than once a month. The practice rate of breast self- examination showed significant differences according to factors, such as age, presence of spouse, educational level, occupation, economic status, smoking, regular exercise and chronic disease. According to age, the highest practice rate of breast self-examination was between the ages of 40-49 and the lowest over the age of 60. The practice rate increased with higher the educational level and presence of spouse. According to occupation, administrative and managerial occupations presented the highest practice rate of breast self- examination. Higher economic status, regular exercise and positive family history of breast cancer each presented high practice rates of breast self- examination. The practice rate revealed higher in those who did not smoke and who had no chronic diseases than others. The greatest reason for performing breast self- examination was decided by myself for health reasons, followed by effect of mass media and promotion by health center. The most common reasons for not performing breast self- examination were don't feel the need, followed by don't know how to perform the exam and don't know about the exam itself. Multiple logistic regression analysis showed that factors, such as over the age of 60, less education, and no experience with mammography all lowered the practice rate of self-breast examination. Inconclusion, the rates of breast self- examination and regular check-ups of people in rural areas, who are characteristically older and have low educational backgrounds, were 28.2% and 9.7%. These results show the immediate need for the education of the methods for breast self- examination to be carried out by health centers in these areas. Such efforts and programs could increase the practice rate of breast self- examination and thereby improve health and enhance the quality of life of women in rural areas.

This study aims to evaluate the impact of varying exposure to dental amalgam on urinary mercury levels in children by measuring the number of amalgam-filled teeth and the variance of mercury concentration in urine over a period of 2 years. A total of 317 (male 158, female 159) elementary school children (1st~4th graders) attending 2 schools in urban regions participated in this study. At 6-month intervals, 4 oral examinations were conducted to check any variance in the conditions of dental caries and the status of dental fillings. Also, urine tests were conducted followed by a questionnaire survey. To elucidate the factors potentially affecting the mercury concentration in urine, t-test, ANOVA, chi-square test and a mixed model were used for the analysis. Regarding the status of dental fillings in line with examination time periods, deciduous teeth had more amalgam-filled surfaces than those filled with resin, whereas permanent teeth had more resin-filled surfaces than those filled with amalgam. A significant relevance was found between the exposure to dental amalgam and urinary mercury levels. Specifically, subjects whose teeth surfaces had been filled with dental amalgam showed higher urinary mercury levels than those who had no dental amalgam fillings. Based on the analysis using the mixed model, the increase in the number of teeth surfaces filled with amalgam was found to be the factor affecting the increase in urinary mercury levels. The urinary mercury levels were found to be highly associated with the exposure to dental amalgam. The more the teeth surfaces filled with amalgam, the higher the urinary mercury levels. Hence, even a trace of dental amalgam fillings can liberate mercury, affecting the variance in the urinary mercury levels. These findings suggest that some criteria or measures should be developed to minimize the exposure to dental amalgam. Moreover, relevant further studies are warranted.

To test the validity of referral of high risk pregnancy in the MCH Center, 6,017 pregnant women who visited MCH Center of South District Health Center for delivery between 1 April 1985 and 31 March 1987 were interviewed on arrival to obtain the data for demographic characteristics and obsteric history and traced to check the delivery outcome. Out of 5,820 women whose delivery outcomes were confrmed, 704 women(12.1%) were referred to other hospital or clinic for high risk factors. The proportion of poor delivery outcome(stillbirth, low birth weight and neonatal death) among referred cases was 4.4% while that of the women delivered at the MCH Center was 2.2% (p<0.01). Decision of the midwives for the referral of high risk pregnancy based on their clinical assessment was consistent with the delivery outcome (good or poor) in 86.5%. Major reasons for referral were premature rupture of membrane(46.5%) and cephalopelvic disproportion(20.0%) and the C-section rates for these cases were 10.1%, 17.6%, respectively. Discriminant analysis of the demographic characteristics and obstertric history for the discrimination of delivery outcome showed that gestational age had the highest discriminant function coefficient(0.88) and it was followed by parity(0.37) and maternal education(0.30). Referral of high risk pregnancy by the midwives based on their clinical assessment was considered to be reasonably valid. However, a risk scoring system for an MCH Center which can improve the validity may be developed if one applies the discriminant analysis for more comprehensive independent variable(including clinical assessment of midwife, demographic characteristics and obstetric history) and dependent variable (including medically indicated C-section, complication of pregnancy and delivery, stillbirth, low birth weight, neonatal death and maternal death).

The aims of this study were to survey, evaluate the accuracy of personal immunization record of vaccination card, and to establish the applicability of personal immunization record for presuming population based immunization rate and evaluation method. In 2005, a population-based survey of 12-35 months old children was carried out in Nonsan, Korea. We conducted household survey and provider check using questionnaire and checklist to obtain data on immunization status for children. Total 11 vaccinations were checked in vaccination card such as BCG, hepatitis b, polio, chickenpox vaccine. For estimating accuracy of immunization status and dates of immunization, we estimated correspondence rate between data from personal vaccination card and data from medical records and immunization registry data. Accuracy of the child's vaccination card by type of National Immunization Program vaccine in whole medical institutions were from 41.8% to 83.2%. Accuracy for the date of vaccination of vaccination card in National Immunization Programme vaccine were from 55.3% to 89.7%. In spite of this study limitations, this study verified the validity of vaccination record of vaccination card substantially, but suggests more efforts to reassure the validity of vaccination card.
