Elementary science textbooks are the major instructional materials which contain sceientific objectives to be acquired by students. The purpose of this study is to analyze the development system, to evaluate the inquiry activity in current elementary science testbooks, and to make suggestions for the improvement of them. The questionnaires were administered to 116 subjects that participated in development of the 5th elementary science textbooks, and 86 of the subjects responded. Based on the data gathered and analyzed in this study, the major findings are as follows. First, regarding the analysis and evaluation of elementary science textbooks. 1. The instructional objectives in elementary science textbooks are analyzed. The proportions of comprehension objectives is 38%, scientific inquiry process objectives 21%, experimental skills objectives 7%, scientific attitudes and interests objectives 4%. 2. The science concepts in elementary science textbooks of the 3rd grade required the preconcrete operational level(82%) and of the 6rd grade required the postconcrete operational level (73%) by J. Piaget. 3. The inquiry activities in elementary science textbooks are emphasizing gathering and organizing results and evaluation, and hypothesizing and designing an experiment. Inquiry index of the elementary science textbooks is 76. This is significantly higher than 35∼50 of America and U.K. 4. The number of questions per class hour is mostly three, and most of them require the students to explain phenomena in nature or in experiment Second, regarding the development system of elementary science textbooks. 1. The budget for and the period of the development of elementary science textbook should be expanded. 2. For the improvement of elementary science textbooks, more abundant resources and time should be used for the basic study and the field trial of textbooks. 3. The elementary science textbook must include the affective objectives as well as the scientific knowledges and scientific inquiry skills. 4. It is not desirable to assign equal number of pages to the content of physics, chemistry, biology, and earth science. 5. Closer cooperation system is needed among the ministry of education, development research center and the field trial schools.

The use of critical pathways for a variety of clinical conditions has grown rapidly in recent years, particularly pathways for patients with acute myocardial infarction. We intend to determine the impact of a clinical pathway on ST-elevation myocardial infarction (STEMI) and to evaluate the efficacy and safety of facilitated percutaneous coronary intervention (PCI) compared with primary PCI. Low risk STEMI patients (ST elevation >0.1mV in more than 2 limb leads or ST elevation >0.2mV in contiguous precordial lead, chest pain lasting more than 30 min without response to nitroglycerin) will be included. All patients will be also treated medically according to critical pathway. STEMI is one of the common diseases in emergency medicine and so it is necessary to establish realistic treatment guidelines. The use of critical pathways will improve the quality of care.

The writers intended to analyse population mobility and life adaptability of in-migrants and natives in the Gumi Industrial Complex. The area of which is under rapid change compared with those of other big cities due to planned industrialization. The study was focused on life adaptability. Life adaptability, we define, as the in-migrant's and native's ability to adapt themselves to the changed social setting. Our tentative findings are as follows: (1) Different from urbanization of other big cites, the economic pulling factor may be the most important factor of population mobility in the Gumi Industrial Complex. (2) Similar to big cities many of inmigrants to the Gumi Industrial Complex are from rural areas but the rate of in-migration from urban area is higher than that of the big cities. (3) About 90% of in-migrants brought their families. (4) More than half of the in-migrants have had non-agricultural occupations. (5) The upper ladder of the occupational hierarchy is occupied by the in-migrants. (6) The in-migrants are more urban oriented and adaptable to new social settings than the natives.

권영웅,우영환,이종원,길성진 중앙대학교 생산공학연구소 1999 생산공학연구소 논문집 Vol.8 No.2

CVT 메카니즘은 공학적 분야에 많이 사용되고 있으며, 특히 CVT의 구동폴리느 중요한 역할을 한다. 본 연구에서는 이륜차의 CTV를 국산화 할 계획의 일환으로 구동폴리를 시뮬레이션하였다. 시뮬레이션한 결과느 구동폴리의 롤로 무게와 마찰 계수, 램프의 각변형을 통해 나온 수치르 장량화한 것이며, 이를 토대로 구동폴리의 각 요소들 즉, 롤러와 유동플랜지, 램프판 간의 상호관계를 규명하였다. CVT(Continuously Variable Transmission) mechanism has been used in many engineering applications. A driving pulley of CVT plays a vital role. In this study, computer simulation for a movable pulley was carried out for the purpose of producing a motorcycle CVT of Korean model. The effects of roller mass, friction coefficient, deformation of ramp plate on a given speed and torque during moving were quantified using the simulation results. Based on the simulation, relations between each component of driving pulley that consists of roller, movable flange and ramp plate etc. were investigated.

禹種仁,權俊壽,洪澤裕 大韓神經精神醫學會 1987 신경정신의학 Vol.26 No.4

We performed the double-blind placebo-controlled study to investigate the therapeutic effect of sodium valproate known as GABA-ergic agent on tardive dyskinesia. 15 out of 31 patients were treated with sodium valproate (maintenance dose: 1500-2700㎎) and the rest of them were treated with placabo over 8 weeks. We checked the severity of tardive dyskinesia by TDRS (Tardive Dyskinesia Rating Scale, Simpson et al, 1979) just before treatment, the 4th week, the 8th week and the 12th week following beginning of treatment. We checked the serum level of sodium valproate at the 4th weeks and the 8th weeks since the beginning of treatment. The results were as follows: 1) Both TDRS scores of 4th week and 8th week were significantly low compared with those of pretreatment in the group treated with sodium valproate (P<0.001), but TDRS scores returned to the pretreatment score at 12th week (4 weeks after withdrawal of medication). There was no significant relationship between serum level of sodium valproate and TDRS total scores. 2) All of the TDRS scores of 4th week, 8th week, and 12th week were significantly low compared with those of pretreatment in the group treated with placebo.(P<0.01) 3) TDRS scores of the group treated with sodium valproate were not significantly different from those of the group treated with placebo at the time prior to treatment, 4th week, 8th week and 12th week.

권혁찬,최숙영,유우종,유관종 충남대학교 기초과학연구소 1995 忠南科學硏究誌 Vol.22 No.2

In this paper, we present the design and implementation of object manager for communication and synchronization in POOSL(Parallel Object-Oriented Specification Language). POOSL is a specification language which is based on object-oriented concepts and provides various granularities of parallelism and communication methods. An object manager handles synchronization of objects and supports three types of communication, that is, synchronous, asynchronous and future type communication. Object manager is automatically generated in the phase of translation of POOSL. We implemented the object manager using lex and yacc.

森林資源化를 위한 山村問題硏究 : 江原道를 중심으로 with Kangwon province as the central region

權五福,禹鍾春 江源大學校 林科大學 森林科學硏究所 1993 Journal of Forest Science Vol.9 No.-

우리나라에서 國內木材消費量은 과거 20-30년 동안에 급격하게 증가했고 최근에는 休養을 위한 森林利用, 水源涵養과 國土保全을 위한 保安林의 必要性이 점차로 증대해가고 있다. 그러나 森林을 조성해야할 森林所有者들이 山村에서 都市로 移動하고 있으므로 森林에 대한 社會의 욕구를 충족시키기 위한 森林活動이 어려워지고 있으며 따라서 都鄙化問題가 중요한 政策課題로 되어있다. 本 論文은 森林資源化를 위하여 山村問題를 분석한 事例硏究이다. Domestic timber consumption has increased dramatically in the past few decades in this country. In addition, there is increasing demand for recreational opportunities in the forest areas and concern for watershed management and soil conservation. However, it is difficult to satisfy these demands for forest resources because many of woodland owerners who make such demands possible move from mountain villages to modern cities. Therefore, whether or not it is in the public interest to invest in rurbanization is a central policy question. This is a case study which deals with mountains village problems for making forest resources.
