In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

이범재,권영배,김태동 안동대학교 환경연구소 2001 환경연구 Vol.1 No.-

In treatment of hazardous wastes like fly ash, landfill has been generally the most economical and easy method of treating this waste in Korea. But there is a stringent restriction on landfill because soil and groundwater contamination is occurred by the leachate from landfill materials. Modified stabilization/solidification technology, to solve these problems in landfill and melting processes, is researched with which we can stabilize heavy metals in solidified matrix. Objectives of this study are development of S/S process technology for stabilization of pollutants in hazardous wastes, and determination of the optimum additives and their mixing ratio for increasing the physical propriety of solidified matrix and reducing the pollutants leaching concentrations. The results of this study are as follows; Solidified matrix' proprieties such as heavy metals leaching concentrations and compressive strength were improved when slag and rice husk ash were used such as pozzolan materials and added additives as sorts of aluminate, sulfate and silicate chemicals. In the case of HS fly ash, when 5% sodium silicate and 10% cement were used as additives, compressive strength was over 90 kgf/㎠ in 28 the curing days and when sodium silicate and slag were added, heavy metal leaching concentrations were under the criteria in the 7 curing day. In the case of KM fly ash, the physico-chemical proprieties (compressive strength of solidified matrix and heavy metal leaching concentrations) were improved over 150 kgf/㎠ in 28 curing days by the additives like slag and rice husk ash (pozzolan materials) and sorts of aluminate, sulfate, silicate, etc.

이상범,배태웅 東亞大學校 1999 東亞論叢 Vol.36 No.-

국내종 뒤영벌족 중 주요 우점종인 호박벌과 좀뒤영벌의 실내정착가능성을 조사하기 위하여 1997년 3월말에서 5월초까지 수원, 지리산과 인천영흥도에서 채집한 두 종의 여왕벌을 상자별로 사육한 결과 다음과 같은 결과를 얻었다. 호박벌과 좀뒤영벌 모두 상자의 재질이나 크기에 따른 산란율 및 성충출현율의 차이는 없었으나 호박벌이 좀뒤영별보다 산란율, 첫일벌 출현율, 50두 이상 일벌출현율, 새여왕벌 출현군체수, 여왕벌 수명 및 군체의 크기 등에서 좋은 성적을 보여 실내사육이 가능한 종이며 방화성 곤충으로서도 개발이 가능한 종이다. For survey of colony performance by foundation queens collected, collection of domestic species of Bombini was made from March to May of 1997 on Kyungki Suwon, Kyungnam Chiri-Mt. Area and Inchun Younghwung-Do in Korea. And queens of two Bombus species was reared at the 4 kinds of wooden case. The results obtained are as follows; Both of Bombus ignitus and B. ardeus were not a difference between the rate of egg-laid and of warker emergence according to the quality of material and size of all of ages. Bombus ignitus is better than Bombus ardens according to the rate fo egg-laid, rate of first worker emrgence, ≥50 heads of worker emergence, rate of new queen emergence, longivity of foundation queens, and size of colonies. So B. ignitus is possible to develop indoor rearing and foraging insect.

The matrix tablet containing sodium alginate and CaHPO₄ can release drugs in a controlled fashion from hydrogel with gelling and swelling due to their interaction as water penetrates the matrices of the tablet. The purpose of this study was to evaluate release characteristics of the matrix tablet varying the amount of sodium alginate, CaHPO₄ and other excipients such as chitosan, hydroxypropyl methylcellulose (HPMC) and Eudragit^ⓡ RS100 in the simulated gastric and intestinal fluid. The practically soluble ibuprofen was used as a model drug. The release profiles of matrix tablet in the gastric fluid as a function of sodium alginate/CaHPO₄ ratio was not pronounced because of low solubility of drug and stability of alginate matrices. However, release rate of drug from the matrix tablet in the intestinal fluid was largely changed when sodium alginate/CaHPO₄ ratio was increased, suggesting that the ratio of sodium alginate/CaHPO₄ was an important factor to control the gelling and swelling of the matrix tablet. The incorporation of other excipients into the matrix tablet also influenced the release rate of drug. The chitosan and HPMC decreased the release rate of drug. No release of drug was occurred when Eudragit^ⓡ RS100 was added into the tablet. The retarded release of matrix tablet when excipients were added resulted from the hindrance of swelling and gelling of the matrix tablet containing sodium alginate and CaHPO₄. The hardness and bulk density of the matrix tablet was not correlated with release rate of drug in the study. From these findings, the ratio of sodium alginate and CaHPO₄ in the matrix tablet in addition to incorporation of excipients could be very important to control the release rate of drug in dosage form design.

가와사끼병으로 진단받고 고용량의 감마글로불린(2 gm/㎏)을 정맥주사 받은 17명의 환아를 대상으로 임상적 효과와 관상동맥의 변화에 미치는 영향을 연구하여 다음의 결과를 얻었다. 1. 대상 환아의 연령은 평균 2.03세로 3개월에서 5세 사이에 분포하였고, 2세 이하가 58.8%를 차지하고 남여의 비는 1.125 : 1이었다. 2. 가와사끼 진단 기준의 6가지 주증상 중 5가지는 전환아에서 나타났으며, 경부 림프선 종창만 64.7%에서 나타났다. 발생 계절은 봄과 겨울에 76.5%의 환아가 발생하였다. 3. 대량의 감마글로불린 주사 직후 평균 11.4시간에 고열이 없어지고 다른 주증상들도 없어지기 시작하였으며, 대부분(82.3%)이 주사후 20시간 이내에는 소실되었다. 주사중 3례(17.6%)에서 오한 및 일시적인 체온의 상승을 보였으나 주사를 중단할 필요는 없었다. 4. 발병 4주 이내에 관상동맥의 확장이 관찰된 경우는 8례(47.1%)였으나, 이들은 모두 경도의 확장이었다. 발병 2개월 후에 시행한 심초음파도에서는 2명(11.7%)에서만 경도의 확장을 보였고, 나머지는 모두 정상으로 회복되어 있었다. 5. 최저 헤모글로빈치, 최대 C-반응성 단백질, 최대 총백혈구수, 최고 적혈구 혈침속도, 혈소판 최고치는, 발병 4주 이내와 2개월 후에 관상 동맥의 변화가 있는 군과 정상인 군 사이에 의미 있는 차이는 없었다. 이상의 결과로 가와사끼병의 치료에 있어서 단일 고용량의 감마글로불린을 정맥주사하는 방법이 심각한 부작용 없이 임상적 증세를 빨리 호전시키며, 관상동맥의 합병증을 줄이는데 효과적임을 알 수 있었다. 따라서 모든 가와사끼병의 급성기에 가능한 빨리 단일 고용량의 감마글로불린을 정맥주사하는 것을 추천한다. The authors studied the effect of single high-dose intravenous gammaglobulin(2 gm/㎏) on the clinical symptoms and coronary artery abnormalities in seventeen Kawasaki patients and obtained the following results. 1. The patients' ages ranged from 3-month to 5-year, with mean age of 2.03-year. The patients under 2-years comprised 58.8%. The ratio of male to female was 1.125. 2. All of the patients showed 6 major diagnostic criteria with one exception of cervical lymphadenopathy(64.7%). The disease occurred mainly spring and winter season(76.5%). 3. Fever subsided within 20 hours' of intravenous gammaglobulin infusion in most of the patients(82.3%) with mean value of 11.4 hours, Transient side effects such as fever and chilling sense, developed in 3 cases(17.6%), but there was no need to quit infusion. 4. Echocardiographically, mild coronary arterial dilation was observed in 8 cases(47.1%) within 4 weeks' of onset. After 2 months' of onset, only 2 cases(11.7%) showed mild dilation. 5. There were no significant difference between coronary arterial dilation group and normal group before 4wk and after 2 mo of onset, in terms of hemoglobin nadir, maximal CRP, maximal WBC count, peak ESR, and peak platelet count. Conclusively, single high dose intravenous gammaglobulin infusion in Kawasaki disease showed effective improvement of clinical symptoms and decrease of coronary arterial abnormality. There fore all the children with Kawasaki disease should be treated with single high-dose intravenous gammaglobulin infusion as soon as possible.

This study was conducted to examine the nitrogen effects on uptake and utilization of major mineral nutrients of the kidney bean (Phaseolus vulgaris L.). The N treatments were five levels, 0, 3, 6, 9, 12 N kg/10a. The kidney bean was cultivated on the upland experimental field in the agricultural ???? research & extensions service of Chungbuk province. The contents and uptake amounts of mineral nutrients were investigated throughout the growth stages of the kidney bean. Higher content of total N in the stem was maintained until 8 days before flowering stage and then decreased gradually. Also, total N content of leaves was increased in the vegetative growth stage, and it was decreased rapidly to 8 days after the flowering stage, and then increased gradually to the initial maturity stage. Total N content of roots was tended to decrease until 8 days after the flowering stage, while that of seed was increased from the flowering stage to the maturity stage. The amount of uptake N of the shoot parts was increased until the flowering stage, maintained similarly from the flowering to 14 days after the flowering stage, and then increased rapidly to the maturity stage, while that of root was increased slowly to the flowering stage and then maintained similarly to the maturity.
