  • Objectives: The purpose of this study was to prevent health problems and environmental contamination resulting from inappropriate management of dental wastes and to provide reference data for revision and supplementation of dental clinic waste management guidelines. Methods: From 640 total of dental clinics registered in 16 cities and counties in Gyeongsangnam-do, 100 (60 in Changwon (Masan, Changwon), 29 in Gimhae, and 11 in Jinju) were included in this study. From July 2010 to September 2010, investigators visited the 100 dental clinics and conducted survey interviews using a structured survey questionnaire regarding disposal methods for liquid wastes (suction pump, spittoon container waste, used liquid disinfectants, and X-ray developer), and disposal methods for solid waste (suction pump, spittoon container waste, and general medical waste). Results: All the 100 dental clinics were found to treat liquid waste from suction pumps and spittoon containers in the same manner as general waste water. Nineteen percent of the clinics treated solid waste that was not filtered through the filter of a suction pump as general waste. Fifty or more percent of the clinics treated solid waste in spittoon containers as general waste. Seventy percent of the clinics used disinfectant solution, although most of them treated used disinfectants in the same manner as general waste water. Some clinics treated used X-ray developer and X-ray fixer in the same manner as general waste water. In most of the clinics, used drapes were washed within the clinic. Conclusions: It was found that waste water and dental wastes at some dental clinics were treated in inappropriately. Thus, in conclusion, the development of guidelines regarding proper management of liquid and solid dental waste at dental clinics is required, and hygiene and environmental training for workers at dental clinics is necessary.

  • Nutrition related factors were investigated in one hundred and two hypertensive patients(Male : 44, female : 58) before they started drug treatment or diet therapy. The mean age of men and women were 49.9 and 53.5, respectively. Among the men, their mean SBP and DBP were 165.8 mmHg/108.4 mmHg. Fifty six point eight percent of men was classified as having in stage 3 hypertension(SBP $\geq$ 180 mmHg, or DBP $\geq$ 110 mmHg) and 45.5% was classified as having low renin hypertension (serum renin < 2.5 ng/ml/h). The proportion of overweight or obesity assessed by BMI($\geq$ 25) or body fat percent( $\geq$ 21%) was 47.7% or 80.9%, respectively. Men showed 19.1% of hypertriglyceridemia(serum TG $\geq$ 200 mg/dl), 42.6% of hypercholesterolemia(serum cholesterol $\geq$ 220 mg/dl), and 17.0% was observed as having serum cholesterol higher than 240 mg/dl. The proportion of men with high risk of cardiovascular disease was 72.3% assessed by atherogenic index( $\geq$3.4). The prevalence of drinking was 86.4% including a daily drinking proportion of 15.8%. Among women, their mean SBP and DBP were 162.6 mmHg/104.3 mmHg. Less women(43.1%) were classified as having stage 3 hypertension and more women were observed in low renin hypertension(55.1%). The prevalence of obesity or overweight assessed by BMI( $\geq$ 25) was 31.0% and 76.3% with body At percent($\geq$28%). Women revealed 24.1% of hypertriglyceridemia and 36.2% of hypercholesterolemia. The proportion of women who showed high risk of cardiovascular disease(atherogenic index $\geq$ 3.4) was 63.8%. The smoking rate was 8.6% and drinking rate was 43.1%.

  • The purpose of this study was to assess the iron nutritional status of college women residing in the Kyungin area. The anthropometric parameters, nutrient intake, and biochemical status of iron were measured for 102 college women. The mean height and weight were 160.3cm and 52.4kg, respectively. The proportion of subjects whose BMI was less than 20 was 41.3%. The proportion of subjects assessed as overweight(25$\geq$25%) assessed by the fat percent(FP) was 53.9%. The mean daily intake of iron was 13.90mg(77.1% of RDA), composed of 0.97mg of heme iron and 12.44mg(69.0% of RDA). When the sources of iron were grouped as rice(including bread), noodle, soup, side dish, and snack, noodle provided, 3.95mg of iron regarded as the highest amount. Subjects were taking 6.72mg(51.4% of RDA) of iron per day from main dishes(rice, bread and noodle). The fifty five percent of the subjects showed iron depletion(serum femitin<20ng/ml)and 33.4% showed suppressed erythropoiesis with iron deficiency(serum ferritin<10ng/ml). The anemic subjects assessed with transferrin saturation (<15%) represented 33.3% of the test population, whereas 11.8% of the subjects possessed less than 12g/dl of hemoglobin. Subjects not satisfied with their body shape were having significantly lower amount of energy intake(p<0.05) than the subjects satisfied with their body shape. College women having mothers who graduated from university had a significantly decreased amount of energy, carbohydrates, fat and vitamin C(p<0.05). The mean RBC and serum iron of the subjects who were on a diet more than one month were lower than those of the subjects who were not on a diet(p<0.05).

  • Various social surveys conducted by mass media and government agencies in recent years in Japan suggest that the percentage of those who believe in religion are between twenty and thirty percent. However, more than seventy percent of Japanese visit Shinto shrines or Buddhist temples during the New year period. Although there are varying interpretations on whether Japanese people are religious or not, detailed research shows the existence of certain religious tendencies among Japanese. I base my estimates on research surveys of college students covering a period of almost ten years. It is helpful for understanding the religiosity of the Japanese to differentiate between "clear-cut religion" and "peripheral religious phenomena." The exact boundary between these two categories, however, is difficult to clearly demarcate. "Clear-cut religion" refers here phenomena which are directly related to established religious organizations such as shrine Shinto, Buddhist sects, or Christianity. "Peripheral religious phenomena" covers such phenomena as fortune telling, mystical phenomena, religious customs and similar matters. It is often said that the younger generations are less concerned with religion. Our seven surveys questioning several thousand college students, conducted between 1995 and 2001, show that only between six and seven percent of the students state that they believe in religion. Additionally, the extent of negative attitudes toward religion quite remarkable. On the other hand, students who take part in conventional ritual such as a New year's visit to a shrine or temple and visiting the graves of ancestors amount to about fifty percentage. In spite of the prevailing negative attitude toward religious groups, these students have apparently kept a certain level of interest in religious customs. Moreover, they show a relatively strong interest in fortune telling, mystical phenomena, or supernatural phenomena. The exact degree of a positive attitude toward peripheral religious phenomena differs according to the level of being informed on these matters. As a whole, they largely rely on information gained from their families and local communities. Therefore, we can conclude that there is a degree of transmission of religious culture among younger generations.

  • 목 적 : 본 연구는 소아, 청소년에게 행해지는 보완대체요법 사용실태에 대한 구체적이고, 다각적인 연구의 필요성이 있었기에 보완대체요법을 접할 기회가 많은 만성질환을 가진 소아, 청소년에서 보완대체요법이 어느 정도 사용되고 있는지, 보완대체요법의 종류에 따른 사용실태를 알아보고, 보완대체요법 사용에 영향을 미치는 인자가 있는지 알아보고자 하였다. 방 법 : 2004년 3월부터 8월까지 관동의대 부속병원 소아과에서 지속적 추적관찰을 해오던 입원 경험이 있는 환아들 중에 만성질환(기관지 천식, 아토피, 간질, 뇌성마비 등)을 앓고 있는 환아(160명)를 대상으로 하였고, 환아와 동행한 보호자에게 설문양식에 따라 면담설문을 실시하였다. 결 과 : 설문 조사에 응답한 만성질환을 앓고 있는 환아는 252명이었고, 그 중 보완대체요법을 시행한 160명(63.5%)을 대상으로 삼았다. 각 질환별 보완대체요법 이용률은 선천성 근병증(100%), 아토피성 피부염(91.1%), 만성 반복성 복통(73.5%), 기관지 천식(72.5%), 만성 설사(50.0%), 뇌성 마비(42.1%), 만성 기관지염(37.5%), 간질(17.1%) 순으로 이용률의 차이를 보였다. 시행한 종류는 식이요법(31.1%), 생약요법(23.4%), 수치요법(16.3%), 마사지(14.2%), 방향요법(8.9%), 침술요법(4.6%), 동종요법(1.3%) 순이었다. 64명(40.0%)이 2가지 이상의 보완대체요법을 동시에 시행하였고, 보완대체요법을 권유받은 경로는 비의사처방에 의한 경우가 133명(83.1%)이었으며, 99명(61.9%)이 보완대체요법의 효과에 대해 긍정적으로 답변했다. 보완대체요법 시행군에 있어서 보완대체요법 사용에 영향을 미치는 인자들 중 부모 연령, 자녀 연령이 통계학적 의의가 있었으며, 부모의 연령이 높을수록 시행경험이 많았고(P=0.001), 자녀의 나이가 어릴수록 보완대체요법을 시행하지 않는 경향을(P=0.002) 보였다. 결 론 : 만성질환을 앓는 환아들은 치료에 있어서 현대의학에 의존하는 반면, 상당수가 보완대체요법을 이용하고 있었으며, 2가지 이상을 동시에 사용하는 경우가 많았고, 그 효과에 대해 긍정적으로 평가하고 있었다. 이와 같은 결과는 국내에서 보완대체요법의 접근성이 용이하고, 긍정적인 측면이 강조되고 있기 때문이므로 무분별한 보완대체요법의 사용을 피하기 위해서는 보완대체요법의 효과와 부작용에 대한 현대의학적인 연구가 더 필요할 것으로 사료된다.

  • Bacterial communities at 10 cm, 100 cm, and 200 cm depths in a 100-year-old lead-zinc tailing heap were evaluated by constructing 16S rRNA gene libraries. In total, 98 operational taxonomic units (OTUs) were identified from 193 clones at a 3% sequence difference level. The OTU number and species richness decreased with the depth. Species composition was significantly different between the three libraries. Fifty-seven percent of the examined clones were Acidobacteria and 27% belonged to Proteobacteria. Other sequences included Chloroflexi, Firmicutes, Chlamydiae, Actinobacteria, Gemmatimonadetes, Nitrospira, and three unclassified OTUs. Alphaproteobacteria, Betaproteobacteria, Gammaproteobacteria, Firmicutes, and Actinobacteria were mainly distributed in the rhizosphere of naturally colonizing plants; however, Deltaproteobacteria, Acidobacteria, and Chloroflexi tended to inhabit the deeper tailings (below the 100 cm-depth).

  • A study was undertaken to determine the incidence of short oestrus cycles and associated serum progesterone levels in Nili-Ravi buffaloes. Forty lactating buffaloes were kept under observation for oestrus activity for a period of sixty days. Blood samples from jugular vein from twenty buffaloes were used to determine associated serum progesterone levels during short oestrus cycles. Incidence of short oestrus cycles was 15.5 percent (Nine out of fifty eight oestrus cycles) and most of the short oestrus cycles occurred between first and second oestrus after calving. Lengths of short oestrus cycles ranged from 6 to 14 days. The most frequent length was 11 days. Serum progesterone levels were lower at oestrus and increased gradually attaining peak levels of 1.3 and 1.8 ng/ml on 7th day of 9 and 11 day short oestrus cycles. One buffalos exhibiting a short oestrus cycle of 12 days conceived which indicated that ovulation took place at the oestrus of short cycle.
