LEE, Min-Jai, HONG, Soon-Woo & LEE, In-Kyu, (Dept. of Botany, Seoul National Univ.) An analytical studies of free amino acid and its relationship among the main groups of green algae (Ⅲ). Kor. Jour. Bot. V (3) : 25-29, 1962. Succeeding the previous papers, nineteen species of marine green algae and three species of fresh water green algae are analyzed to the free amino acid patterns by paper chromatogram, and it has been described as containing significant qualities of the pattern in relation to phylogenetic studies. Those seem to have a tendency of recognizable pattern on inter-Orders and inter-Phyla of marine algae. And the patterns of fresh water and marine green algae are also carried out referring to these studies.

In this study, a precipitation method, one of the most effective liquid phase reaction, was adopted in order to prepare high-tech Al₂O₃/ZrO₂ composite ceramics. Al₂(SO₄)₃·18H₂O, ZrOCl₂·8H₂O and YCl₃·6H₂O were used as starting materials and NH₄OH as a precipitation agent. Fine powders were prepared at optimum calcination condition. Sinterability of each fine powder and the effects of ZrO₂ on the grain size and mechanical properties of Al₂O₃ were investigated. The composition of Al₂O₃/ZrO₂ composites was fixed as Al₂O₃-15v/o ZrO₂(+3m/o Y₂O₃). The effect of MgO on the grain size of Al₂O₃ZrO₂ ceramics was also investigated.

Renal vein thrombosis (RVT) is not an uncommon condition amongst patients with nephrotic syndrome or malignancy. Septic pulmonary embolism (SPE) is associated with risk factors such as intravenous drug use, pelvic thrombophlebitis, and suppurative processes in the head and neck. However, acute pyelonephritis is a rare cause of RVT and SPE. Case reports on RVT and SPE due to acute pyelonephritis are rare. In most of the earlier cases, patients had underlying conditions such as diabetes mellitus, renal carcinoma, calyceal stones, and hyperhomocysteinemia. We report a case of acute pyelonephritis complicated by RVT and SPE that occurred in a patient without any predisposing risk factors for thromboembolism. RVT and SPE were diagnosed using computed tomography and ventilation/perfusion scan. The patient recovered with antibiotics and anticoagulation therapy without any surgical interventions.

Objectives : There is a increasing need to recruit and retain more psychiatrists who can plan and implement organized programs to work with chronic mentally ill patients in community settings. The aim of study is to discover what training is currently in place to prepare psychiatrist for work in "community" or "public" settings. Methods : Survey questionnaires were mailed to 85 residency training directors and 10 leaders of community mental health in 2005. Response rate was 75%. Results : Academic seminar about community mental health were not administered to residents in 63% of training hospitals. Forty one out of 64 training hospitals had community mental health rotation programs, Community mental health center (50%) and day hospital (36%) were the most common type of programs. Few general hospital had affiliation with community mental health programs. The amount of time for clinical rotation varied from less than three months part time to 6 months fulltime, with most frequent form of one day per week for three month in second or third year of psychiatry residents. Conclusion : Further steps are needed to improve residency training curricula and to encourage well qualified psychiatrist to choose careers in community psychiatry.

This paper aims at providing a concrete plan to improve technical and vocational teacher education in the College of Industrial Education of Chungnam National University. It is intended to propose a practical four-year regular and short-term course. Also, the estimated required facilities is included in this study as well as their management. The main conclusions and recommendations are summarized as follows; 1) The numbers of students enrollment should be reduced to 220 students which is the approximate number of future demand. 2) In order to offer to the students a broader education and to cope with the increase/decrease in demand of technical and vocational teacher within a specific field, the 8 department existing at the present (Department of Architecture Engineering Education, Civil Eng. Educ., Metallurgical Eng. Educ., Mechanical Eng. .Educ., Electrical Eng. Educ., Electronic Eng. Educ., Industrial Chemistry Educ. and Industrial Technology Educ.) would be combined into 5 (Department of Construction Engineering Education, Mechanical Eng. Educ., Electrical Eng. Educ., Industrial Chemistry Educ. and Industrial Technology Educ.). 3) The short-term course program is recommened to provide additional training and education to those candidates who already have experience in technical fields to meet an occasional demand. 4) It is necessary to add the Teaching Profession Section in the administrative organization of the College.

This study was carried out to easily cope with a reduction of time and accuracy on the pattern making, automatizaion o f process, and modificatory operation of pattern design as autograding it by 44, 55, 66, 77 snf 88 on the basis of such a basic pattern, after develop-ed the program of basic battern making of bodies for women in twenties by using personal computer which is generalized in these days. The reslts are as follos 1. This study could develop the program also for auto-ma-king of complicate pattern line, because of programming of pattern line modified and base dot necessary for the basic pattern making. 2. A pattern fitted to their own body pattern can be made as carring out the program by inputting a body item(posterior waist length, posterior shoulder width, across back widteh, BNP to bust point, and nipples'breadth) that is necessary for the pattern making.

The purpose of this study is to present the mathematical interpretation on joint torque while being normal gait which include the muscle tension and use equation of motion with a double rigid-pendulum model. then, the estimates of the stance and swing phase were obtained from photoghaphs. When the angel of thigh(θ₁) and calf (θ₂) of lower leg measured from vertical direction to counterclockwise are compared, the results as follow; 1. It is possible to interpret the mathematical model on the joint torque of lower extremity with double rigid pendulum model. 2. With the conition of double rigid pendulum model, the length of center of mass does not effect at the change of angle.

The purpose of this study was to find out the effect for carrying load of 20% & 40% of body weight by means of two different carrying systems on selected kinematic characteristic describe the walking gait patterns. 1. The gait cycle-time for loading of upperpart of body during walking gait was the longest at back pack system Ⅱ. The period of double support of back pack system condition tended to increase with loading of body and swing period tended to decrease. 2. Angle displacement of knee and ankle of joint was the most large at toe off phase and the most short at heel for gait cycle period. The angle displacement of ankle and knee in the condition of exteral load of body was slight increase at double pack system condition and decrease at back pack system condition. 3. The body posture and gait pattern for double pack condition were more similar to those for normal walking than for the back pack system condition, suggest that the double pack system was Kinematically more effective than the conventional back pack system for carrying the loads investigated.
