In previous communications$^{1-6)}$, the results of the preliminary phytochemical examinatioins of 261 plant samples which have been used in medicine in Korea were reported. In continuation of this program we now present in Table I the results of chemical examination of another 92 species, belonging to 80 genera nad 48 families, which were screened for the presence of alkaloids, saponins, terpenoids, and flavonoids. The list of folk medicines described by Lee$^{7)}$ was used as a guide in the selection of plants to be tested.

The blade failures are identified as the leading cause of unplanned outages for steam turbine. Most investigations of the failures are limited to material tests, chemical analysis of deposits, and possibly examination of material specimens. But to correct a blading problem requires more than positive identification of the mechanisms involved. An analytic procedure capable of predicting stress and dynamic characteristics of turbine blades is presented to increase steam turbine availability by decreasing blade failures. Finite element method is used to model and predict natural frequencies, steady and dynamic stresses of turbine blades. The procedure is illustrated by the case study. This procedure is used to guide, and support the plant manager's decision to avoid a costly, unplanned outage

The purpose of t his paper is to database each factors from experimental results and develop the servo-controlled feeding system on these database. At first, spring back and bending farce are analyzed by basic theory of bending processing. In database, through practical experiment by the expert various types of bending angel and thickness of plate are tested and classified with SB34P and Aluminum. For the development of servo-controlled feeding system, automatic feeding system is designed and manufactured with ball screw and LM guide and performance of the developed feeding system is tested under condition of standard machine tool examination. Also, Mechanical consideration of mainframe in press brake, development of controller based on NC, program for servo-control are studied. Finally, based on experimental data, the system is operated and compared with theoretical data

The pupillary size and movement are controlled dynamically by the autonomic nervous system; the parasympathetic system constricts the iris, while the sympathetic system dilates the iris. Under normal conditions, these constrictions and dilations occur identically in both eyes. Asymmetry in the pupillomotor neural input or output leads to impaired pupillary movement on one side and an unequal pupil size between both eyes. Anisocoria is one of the most common signs in neuro-ophthalmology, and the neurological disorders that frequently cause anisocoria include serious diseases, such as vascular dissection, fistula, and aneurysm. A careful history and examination can identify and localize pupillary disorders and provide a guide for appropriate evaluations.

Anemia can be defined as a reduction in blood hemoglobin concentration or red cell mass relative to age matched normal values. Clinical presentation may range from obviously pale and lethargy to an incidental finding during screening of an otherwise well appearing child. The differential diagnosis of anemia in each instance is broad with numerous possible etiologies. A careful history and physical examination as well as complete blood count, peripheral blood smear and additional laboratory tests are necessary in defining underlying cause of the anemia and guide in further treatment plans. In addition, Iron deficiency anemia and anemia of inflammation are common causes of mild to moderate anemia in children, but most pediatricians have some confusions to differentiate these two entities.

기관내 지방종은 문헌상 매우 희귀한 종양으로 알려져 있다 본 환자는37세의 건강한 남자로 간질성와 호흡곤란의 증상으로 지난 6개월간 기관지천식의 진단하에 치료받아 오던중,본원에서 흉부전산화 단층촬영과 기관지내시경검사상 흉부기관의 내강에 위치한 구형의 종양이 기관내강의 대부분을 막고 있음을 알고 기관지내시경검사하에 용종제거술루우프를 이용하여 전기소작과 더불어 종양을 완전히 제거하였다 환자는 수술후 3일 째 퇴원하였으며,수술후 1, 6개월에 시행한 기관지내시경상 재발없이 양호한 상태를 유지하고 있다.

The authors installed implants combined with guided bony regeneration (GBR) using autogenous tooth bone graft material in the patients. In one patient, GBR and simultaneous implant placement were performed. In two patients, GBR was performed and the implants were placed after 6 months. All patients achieved favorable clinical outcomes. Excellent osteoconductive bony healing was observed in the 6 month histology examination after the bone graft.

Comprehensive work is done for flows by an axial fan by experimental research. The present model fan is used for air handling device for out-door unit of an air conditioner in home appliance. PIV(Particle Image Velocimetry) system and wind tunnel are adopted for measurements of flows and performance evaluation, respectively. Major experimental conditions are the installation depth of a fan into a bellmouth of it. Optimal position of a fan in an inlet guide tube is observed by examination of fan-performance and flows in both upstream and downstream of the fan. Consequently, in the case of the fan inserted in half depth into the inlet tube, the efficiency of fan shows its maximum value and flow patterns is also streamlined.

For evaluation on effects guiding fasciola prevention of which the specimens collected from 6,011 cows rears at 387 farms in inchon were tested to egg count examination for 4 years(1987-1990), and the questionnaire checked up 181 dairy farms for 2 years (1989-1990). The results were summarized as follows. 1. A yearly variation of fasciola infection rate above 31% were 83% In 1987, 58% in 1988, 25% in 1989, noninfection in 1990. 2. The average concentration in feces of infected dairy cattle was 79.4% below 1-10 eggs for 4 years(1987-1990) 3. In the results of the questionnaire for 2 years(1989-1990) the farmers gradually took interest in fasciola prevention. 4. To re-dose anthelmintics was 75.4% in 1989 and 82.5% in 1990 after 5∼7 months from previous dosage.

건강검진을 위해 병원을 내원한 수검자 중 위장조영검사를 선택한 수검자를 대상으로 서비스 만족도 개선을 위해 본 연구를 시행하였다. 수검자를 대상으로 설문조사를 시행하였으며, 2014년 5월부터 2개월 동안 내원한 수검자 147명을 교육 전 대상자로, 2014년 7월부터 2개월 동안 내원한 수검자 164명을 교육 후 대상자로 선정하였다. 교육 전 대상자에게 불안감, 설명필요, 설명방식, 조영검사 만족도 등을 조사하여 이를 바탕으로 동영상을 제작하였으며, 교육 후 대상자에게 제공하여 불안감 변화, 동영상 설명 만족도, 도움정도, 재 시청 의향 등을 조사하였다. 교육 전 측정한 평균값은 불안감 2.62, 설명필요성 2.52로 측정 되었으며, 설명방식은 대상자의 78.2%가 설명 안내 동영상을 선택하였고, 조영검사 만족도는 1.55로 조사되었다. 교육 후 측정한 평균값에서 불안감의 변화는 1.45, 동영상설명만족 2.80, 도움정도 2.79, 재 시청 의향은 2.80으로 측정되었다. 교육 전, 후 집단 간 T-test에서 불안감 변화, 만족도 등에서 통계적으로 유의한 차이를 보였으며(p<0.05), 위장조영검사에 대한 동영상 교육을 통한 사전 정보제공이 환자의 불안감을 감소시켰고, 검사만족도는 증가 시켰음을 알 수 있었다.
