Background : Congenital rubella syndrome (CRS) can be controlled by vaccination. Because rubella is typically a childhood disease, occurring predominantly in the 5 to 14 year age group, female school teachers nay be a high-risk population for CRS. Objectives : To determine the prevalence rate of rubella antibodies in school teachers of child bearing age. Methods : The study population consisted of primary, middle and high school teachers of child bearing age. The subjects were aged 35 years and younger, and consented to immunoglobulin (Ig) level testing using the ELISA method. Results : The positive rate of IgG was 77.9% in the study subjects (n=314). Sixty-three teachers (21.4%) were susceptible to rubella infection. Thirty-seven teachers (11.8%) had a history of rubella vaccination. Among the female teachers with no vaccination history, the proportion of negative IgM and IgG was 21.7%, and the proportion of positive IgM was 2.9%. Seventy-nine percent of the study subjects did not know that they should not become pregnant for three months after receiving the rubella vaccine. Conclusion : School teachers of child bearing age should be considered a high risk group for CRS, and should be vaccinated if they are found to be seronegative.

This study was desiged to investigate the effects of calcium supplementation on the metabolism of sodium and potassium and blood pressure in seven healthy college women, aged from 19 to 21 years old. For this purpose, metabolic studies were conducted for two weeks. During the first week, the subjects ate experimental diet of which nutrients composition was similar to their usual intake. And during the consecutive second week, they ate the same experimental diet supplemented with 500mg or calcium daily. The results were summarized as follows : 1) Urinary excretion of sodium was significantly increased(p<0.05), but fecal excretion and retention of it was not affected by supplementary intake of calcium. 2) Potassium balance was not changed after additional intake of calcium. 3) Serum sodium and potassium level decreased significantly(p<0.05), but aldosterone and renin levels in serum were not changed by additional intake of calcium. 4) Systolic blood pressure(SBP) was not affected, but diastolic blood pressure (DBP) was significantly decreased (p<0.05) by supplementation of calcium. The above results showed that daily supplementary intake of calcium can be effective to decrease diastolic blood pressure through inducing the change of sodium metabolism in young women eating usual Korean diets.

The nutrients such as protein, calcium, iron and all three of them, either by natural or chemical substances were added to the recipes of yeast breads. Acceptability test was carried for the each formulated bread before selecting eight experimental diets. Sixty albino rats were separated into ten dietary groups including eight enriched breads and two control diets of plain breads from the market, which were used as the carbohydrate sources of the each basal diet. Experimental regime was seven weeks. The growth rate, hematology, total serum protein and organ weights we compared. Generally animals on the enriched bread showed the better growth rate than the rats fed control diet. Diet H enriched protein, iron and calcium by natural foods, brought up the highest weight gain among all of the rats. Hemoglobin concentrations of the rats on the diet H and G (enriched with three nutrients by chemicals) were 14.3 and 14.2 gram % comparing with other two control groups (12.9 and 13.1 gram%). Rats on diet K (fed nothing but diet H enriched bread) showed the significantly higher growth rate, total serum protein and hemoglobin level than these on the diet L (fed only plain bread from the market).

This study was performed to investigate effects of hesperidin and naringin on linpid peroxide formation and antioxidative enzyme activities in rats. Thiobarbituric acid reactive substance (TBARS) concentrations were measured in plasma and liver. Catalase, superoxide dismutase, and glutathione peroxidase activities were measured in erythrocyte and liver. Forty-nine male Sprague-Dauley rats weighing 275.3$\pm$3.3g were blocked into seven groups according to body weight and were raised fro four weeks on diets containing 0.25, 0.50 or 1.00%(w/w) hesperidin or naringin . Food intake, weight gain , food efficiency ratio, and weights of liver, kidney, spleen ,and epididymal fat pad were not significantly different among groups. In 0.50 and 1.00% naringin groups , plasma TBARS concentrations were significantly decreased with a dose response patter. In 0.25, 0.50 and 1.00% hesperidin groups, liver TBARS concentrations were significantly decreased without a dose dependent patter. Antiosidative enzyme activities in erythrocyte and liver were not significantly affected by type and amountof dietary bioflavonoid, but in the 1.00% hesperidin group, catalase, superoxide dismutase, and glutahione perosidase activities in linver showed a tendency to increase. In conclusion, naringin inhibited lipid peroxide formation with a dose response pattern in plasma without changing the activities of antioxidative enzymes. Hesperidin adminstration, regardless of the level in the diet, inhibited lipid peroxide formation in liver.

Purpose: This study was performed to evaluate Korean nurses' knowledge about hereditary colorectal cancer (HCRC). Methods: A modified 15-item HCRC knowledge questionnaire was developed based on previous research. One hundred and forty-eight nurses have completed the questionnaire from February to April, 2011. Results: The average score of nurses' knowledge was $11.25{\pm}1.54$. Ninety-seven percent of nurses knew about colonoscopy check up schedule and family pedigree. However, only 20% of nurses knew about the rate of passing on mutation genes to offspring and risk of developing CRC among carriers. Only 13.5% of nurses had previous genetic education experiences. Working in oncology units, taking care of CRC patients, and participating in genetic education were not associated with nurses' HCRC knowledge. Conclusion: Various factors influence nurses' knowledge about HCRC. Repeated study with larger national sample of nurses is recommended to identify the factors affecting nurses' knowledge level in order to develop efficient genetic education programs for HCRC patients and their families by nurses.

To know a degree of pollution in agricultural products cultivated around 4 unworked mines located in Chollanam-Do, we investigated a concentration of heavy metal and trace metal to provide the basic data for its residual limits. 28 samples of seven kinds of agricultural products(lettuce, onion, potato, radish, pepper, pumpkin, bean) collected from 4 unworked mines located in Chollanam-Do in 2001 were analyzed by Mercury Analyzer for mercury and Atomic Absorption spectrophotometer for Pb, As, Cd, Cu, Mn, and Zn. Hg contents were detected N.D. ∼trace level(0.01 ppm and less) and As content were detected N.D. ∼ 0.029 lpm but most of same)leE were not detected. Cd contents were detected N.D∼0.124 ppm. The results of Hg, As, Pb and Cd content showed that for all the 7 species of agricultural products studied, none have accumulated levels dangerous enough to Pose health problems. The average contents of Cu were 3.070 ∼ 7.825 ppm in bean, the Mn were 3.688 ∼23.935 ppm in lettuce ailed the Zn were 5.690 ∼21.171 ppm in bean, respectively.

A multichannel smart sound sensor capable to detect and identify sound events in noisy conditions is presented in this paper. Sound information extraction is a complex task and the main difficulty consists is the extraction of high­level information from an one-dimensional signal. The input of smart sound sensor is composed of data collected by 5 microphones and its output data is sent through a network. For a real time working purpose, the sound analysis is divided in three steps: sound event detection for each sound channel, fusion between simultaneously events and sound identification. The event detection module find impulsive signals in the noise and extracts them from the signal flow. Our smart sensor must be capable to identify impulsive signals but also speech presence too, in a noisy environment. The classification module is launched in a parallel task on the channel chosen by data fusion process. It looks to identify the event sound between seven predefined sound classes and uses a Gaussian Mixture Model (GMM) method. Mel Frequency Cepstral Coefficients are used in combination with new ones like zero crossing rate, centroid and roll-off point. This smart sound sensor is a part of a medical telemonitoring project with the aim of detecting serious accidents.

Pharmacy residency program in Korea was first implemented in Seoul National University Hospital in 1983 to train hospital pharmacists regarding theories and practice which were not appropriately educated in the colleges of pharmacy. There are currently seven hospitals operating the program in Korea, and all of those are located in Metropolitan Seoul area. Most hospitals administer examination and interview to select competent pharmacists while some other hospitals select those based on paperwork and interview tests. Although the program contents are mostly similar, some variation were identified between the programs. Title conferred after accomplishment of the program has not been officially accredited by educational authority. In June of 2008, Korean Society of Health-System Pharmacists promulgated an internal regulation as an attempt to standardize the program contents and to encourage efficient management of the program. Since the regulation has now been effective, it is expected that the regulation may help clinical pharmacy education in Korea move toward advanced level.

This study was designed to determine changes of serum glucose and lipid levels in noninsulin dependent diabetes mellitus patients during different doses of docosahexaenoic acid (DHA)-rich fish oil supplementation. All patients had a fasting blood glucose of less than 180mg/dl, a LDL-cholesterol of less than 160mg/dl, and a triglyceride of more than 160mg/dl. None had clinical evidence of renal, hepatic or coronary vascular disease. Sixteen patients served as control. Seven patients ingested 2.00g of fish oil(low dose group), consisting of 0.30g eicosapentaenoic acid(EPA) and 0.55g DHA. The group of modest dose(n=9) was provided 3.91g of fish oil, consisting 0.59g EPA and 1.08g DHA. After 4 weeks, serum triglyceride concentration showed a mild but nonsignificant elevation in control group, a 9% decrease(194 to 177mg/dl) in the group of low dose of fish oil and a 28% decrease(206 to 161mg/dl) in the group of modest dose. The level of high density lipoprotein(HDL), HDL2, HDL3 and total cholesterol in all groups were not changed. There was a mild increase in malondialdehyde and low density lipoprotein(LDL)-cholesterol concentration and decrease in $\alpha$-tocopherol concentration. However, these changes were not significant.

1992년 3월 한 달 동안 대구시와 경상북도 경주군 감포읍에 위치한 국민학교 각 1개교 1, 2, 3학년 학생 268명(남자 : 136명, 여자 : 132명)을 대상으로 거주지역 및 그 외 관련 인자에 따른 두발중 연농도를 조사하였다. 국민학생들의 성, 연령, 부모의 직업과 흡연력, 두발 세척제의 종류, 손톱을 깨무는 버릇 및 의복과 손의 청결 상태를 조사하였고, 두발중 연농도를 flameless furnace atomizer가 부착된 atomic absorption spectrophotometer를 이용하여 측정하였다. 대구지역 거주학생의 평균 두발중 연농도는 $8.7{\pm}2.9{\mu}g/g$으로 감포지역의 $7.7{\pm}2.2{\mu}g/g$에 비해 유의하게 높았다(p<0.01). 대구지역에서는 72.8%, 감포지역에서는 80.1%의 학생들이 두발중 연농도 $5.1-10.0{\mu}g/g$에 분포하였고, $15.1{\mu}g/g$이상에서는 대구지역은 7명, 감포지역은 1명이었다. 두발중 연농도에 영향을 미치는 인자들 중 손의 청결상태(청결 : $7.4{\pm}2.7{\mu}g/g$, 불결 : $9.3{\pm}2.6{\mu}g/g$)에 따른 두발중 연농도의 차이는 유의하였으며(p<0.05), 성, 부모의 직업 및 흡연력, 세척제의 종류 및 손톱을 무는 버릇에 따른 두발중 연농도의 차이는 유의하지 않았다. 거주지역 및 관련인자들을 포함한 다중회귀분석에서 거주지역(회귀계수 : 1.152)과 연령(회귀계수 : -0.511)이 유의한 변수로 나타났으며 다른 변수들은 유의하지 않았다. 본 연구를 통하여 두발중 연농도의 측정이 연중독을 예방하기 위한 선별검사의 수단으로 그리고 연의 오염이 심한 지역에서의 오염 감시수단으로 이용 가능성이 있다고 본다. 그러나 혈중 연농도와 대기 및 토양 등 주변환경의 연농도의 측정을 포함한 정밀한 역학적 연구가 필요할 것으로 생각된다.
