This study was carried out to evaluate the pollutant removal efficiencies of the advanced drinking water treatment using ozonation process. For raw water, Nakdong River was used. By conducting batch test of ozonation efficiencies of the ozonation were 94 to 92%, respectively. Removal efficiencies of single VOC compound or mixed VOC compounds in the raw water were 80% to 90% by the ozonation with 2 mg/ℓ dosage and 10 minutes contact time. Removal efficiencies of ABS by the ozonation with 1 mg/ℓ, 3 mg/ℓ dosage and 20 minutes contact time were 83% to 96%, respectively. Almost 67% of chlorophyll-a at the concentration of 38.㎍/ℓ was removed by ozonation at ozone dosage of 1mg/ℓ for 20 min. considering the efficiency of ozone utilization and water treatment, the most effective ozonation could be obtained with high ozone dosage and short and short contact time.

We observed clinical features in 43 patients with acute metabolic complications of diabetes mellitus, diabetic ketoacidosis 36 cases and hyperosmolar nonketotic coma 7 cases who were diagnosed and treated in Chunangnam National University Hospital from Jan. 1988 to Dec. 1992. The range of age of the patients with diabetic ketoacidosis was from 2nd decade to 9th decade. The diabetic ketocacidosis was most frequent in the 4th decade(22.2%). But the range of patients with hyperosmolar nonketotic coma was from 6th decade to 9th decade and that compications was most frequent in 6th decade. There were no significant sex difference in the groups of acute metabolic complications. The altered consciousness was the most common complaints both groups of diabetic ketoacidosis and hyperosmolar nonketotic coma. Omission of insulin therapy, infection, and fasting were the most common precipitating factors for the development of diabetic ketoacidosis and hyperosmolar nonketotic coma. Only 3(8.3%) out of 36 patients with diabetic ketoacidosis were presented as the initial manifestations of diabetes mellitus. The mortality rates of the patients with diabetic ketoacidosis and hyperosmolar nonketotic coma 5.6% and 28.6%, respectively.

The study was performed as follows: (1) analyzing the related literatures, documents, records review, (2) need analysis of farmers and members ig rural development organizations in terms of farmer's lifelong learning, (3) consulting experts. The following four findings are the results of this study: (1) Korean national agricultural college should be headquarter of farmer's universities and be approve for lifelong learning credit. Also, agricultural technology & extension centers should run educational program for the lifelong learning credit. (2) For the doing role of headquarter of farmer's university, division of lifelong learning should be add to department of technology training in Korea agricultural college. In relation with this, vision, mission and strategy of division of lifelong learning were suggested. (3) Steps for introduction of credit bank system of farmer education were suggested. Also standard curriculums of 'farming associate degree' and 'agricultural management bachelor's degree' were developed through analyzing existing standard curriculum related with agriculture, analyzing need of farmer, analyzing curriculum of farmer's university, analyzing curriculum of agriculture major. (4) For farmer who do not have high school graduate, two solutions were suggested which are approving farmer's education and one-stop lifelong learning model.

현재 금형공장에서는 변화하는 시장에 빠른 반응을 보이고, 생산하고 있는 제품의 높은 품질과 낮은 가격을 보장하기 위하여 기존 시스템과 인터넷을 접목하려는 많은 시도를 하고 있다. 금형공장에는 ETO(Engineering-To-Order) 방식의 제조방식과 사출금형의 특수성으로 인하여 표준견적 시스템의 개발이 어렵다. 그리고 영업과 수주에 반영할 객관적인 정보가 없으며, 고객의 요청 시 실시간으로 확인 가능한 정보가 존재하지 않는다. 이러한 금형공장의 특징을 반영하고, 문제점을 극복할 수 있는 협업적 전자주문 처리 시스템의 프레임윅(framework)을 설계하고, 또한 각 세부 모듈인 견적가격 산정기능(Cost Estimation Tool), 납기 가능일자 산정기능(Leadtime Tool), 주문상황 응답처리 기능(Order Status Tool), 작업상황 파악기능(Shop Status Tool)을 설계한다. 그리고 현장 적용이 가능하도록 하기 위하여 금형공장의 업무 프로세스를 분석한다. 그리고 주문처리 프로세스의 UMM방법론 모델링을 통하여 윈형(prototype) 시스템을 설계 및 개발하고자 한다.

For the patient with stenosis of upper digestive tract caused by either benign or malignant process, esophageal dilatation is an important therapeutic modality. We reviewed retrospectively 39 cases treated by Savary-Gilliard dilatation for upper digestive tract stenosis, and results were follows : (1) Dysphagia was improved in 95% of the patients. (2) Eight patients(20%) sufferd perforation, five of them were managed with conservative medical measures, others were managed operatively. (3) In the cases with benign stenosis dysphagia was not noticed for 8.8 months, but with malignant stenosis dysphagia was reappeared after 2.8 months despite concomitant chemoradiotherapy. In conclusion, Savary-Gilliard dilatation was an effective measure for symptome due to upper digestive tract stenosis, but more careful attention for perforation should be necessitated. Also another therapeutic modality for treatment of malignant stenosis was inevitable.

Neonatal lupus is a rare syndrome occurring In neonates with tranplacentally acquired maternal autoantibodies, In particular anti-SSA/Ro-SSB/Ra antibodies. Manifestations include congenital heart block, cutaneous lesions, thrombocytopenia, neutropenia, pulmonary or neurological disease and hepatitis. The non-cardiac manifestations resolve by 6 months of age, congenital heart block is irreversible. We experienced a case of neonatal lupus with congenital complete heart block in a newborn of asyptomatic mother with anti-SSA/Ro-SSB/Ra antibodies.

김종우,박찬,김주환,허석,김동규,이동길,조영도,박삼규,Kim, Jong-Woo,Park, Chan,Kim, Ju-Hwan,Heo, Seok,Kim, Dong-Kyu,Lee, Dong-Kil,Jo, Young-Do,Park, Sam-Gyu 한국암반공학회 2015 터널과지하공간 Vol.25 No.3

본 연구에서는 최근 재개발되고 있는 정선지역의 철광산에서 현장 초기지압 시험과 수많은 암석 실내시험을 실시하였다. 본 광산의 측압계수는 심도가 깊어질수록 작아지는 경향을 보였으며 평균값은 1.10으로 나타났다. 본 광산에 주로 분포하는 네 가지 암종인 백운암, 규장암, 화강암, 철광석에 대한 실내시험을 통해 암석의 단위중량, 공극률, 흡수율, 탄성파속도, 일축압축강도, 영률, 포와송비, 인장강도, 쇼어경도, 내부마찰각, 점착력 등의 각종 역학적 특성을 조사하였다. 실내시험 결과의 통계분석을 통해 암종별 물성을 비교하였고 물성 상호간의 관련성을 검토하였는데, 철광석보다는 규장암이나 화강암의 강도특성이 더 컸으며 암석 물성 간의 일반적인 상관관계와는 반대되는 현상도 발견되었다. 또한 Mohr-Coulomb 파괴조건과 Hoek-Brown 파괴조건을 적용하여 네 가지 암석의 파괴조건을 해석하였다. In this study, both in-situ stress measurements and a lot of laboratory rock tests were conducted at a metal mine in Jeongseon, Korea. The stress ratio obtained from in-situ stress measurements showed a tendency to decrease according to depth below surface and its average value was 1.10. The mechanical properties such as unit weight, absorption ratio, porosity, elastic wave velocity, uniaxial compressive strength, Young's modulus, Poisson's ratio, tensile strength, shore hardness, friction angle and cohesion were investigated for the four different rocks mainly distributed at a studied mine, which were dolomite, felsite, granite and magnetite. The mechanical properties of the four different rocks were compared by means of statistical analyses, whereupon the felsite and the granite turned out to have more strength characteristics than the magnetite. The correlation of mechanical properties was also investigated, whereupon a few results against the general correlation were found out. The failure criteria of the four different rocks were finally discussed by means of both Mohr-Coulomb criterion and Hoek-Brown criterion.

The purpose of this study is to evaluate hospital pharmacist's double-check task of outpatient prescription since separation of dispensary from medical practice carried out, which is being shifted to pharmacists out of hospital gradually. We analyzed 2,613 conference call on prescription out of one-year 488,481 outpatient prescription made in SNUH(Seoul National University Hospital). And it is classified and analyzed by month, by department and by conference call item. This study can provide useful information for doctors and pharmacists. Consequently, the doctors can avoid prescription errors. And the pharmacists can promote the capacity of double-checking prescriptions.
