  • The purpose of this study is to examine the appropriateness of Regulatory Impact Analysis(RIA) in terms of the technological regulation impact assessment in order to confirm whether the current RIA process reflects the important characteristics of technological regulation. This paper develops a logical framework for analysis of technological regulation and evaluates the appropriateness of the RIA statements submitted by the government departments. From the viewpoint of [technological feasibility of regulation], [synthesis of domestic technological norms], [synthesis of international technological norms], as a result of evaluating the contents of the actual RIA statement on the basis of objective facts, feasibility of alternative analysis, and expert judgment, only 23.4% of the RIA statements were judged "appropriate", and there were no particular differences among the government. As a result of reviewing the appropriateness of RIA statements according to regulatory attributes, the appropriateness of RIA statements on technological regulation with social regulatory and indirect regulatory attributes was rather high. In sum, the level of Korean RIA statements is insufficient to carry out the practical meaning of technological regulation impact assessment. That is, as each government department adopts technological regulation, the understanding of the technological properties of the regulation may not be complete. The RIA statement that does not adequately reflect the technological rationale, hinders the careful review of other regulatory alternatives by exaggerating the feasibility of the technology regulation, at the same time leads to the serious problems that impede the acquisition of competitiveness of companies and the public in the global competition system.

  • The word spawn is derived from an old French verb, espandre, meaning to spread out or expand. Spawn is also defined as "the mycelium of fungi, especially of mushrooms grown to be eaten, used for propagation". The effects of bag spawn to sawdust substrate on the growth of Pleurotus ostreatus were conducted. The duration of mycelial growth and days of pinhead formation of bag spawn(2.5kg) were 18~19days and 7~8days, whereas bottle spawn ($1,000m{\ell}$) was 18days and 6days, respectively. The yield of mushroom fruitbody was that bag spawn is 100~118g, bottle spawn is 95~115g. In economical analysis, bag spawn is increased to 50%, compared to bottle spawn in relative income.

  • Unlike ordinary situations, deifinitions play a very important role in mathematics education in schools. Mathematical concepts have been mainly acquired by given definitions. However, according to didactical intentions, mathematics education in schools has employed mathematical concepts and definitions with less strict forms than those in pure mathematics. This research mainly discusses definitions used in geometry (promising) course in primary schools to cope with possibilities of creating misconception due to this didactical transformation. After analyzing problems with potential misconceptions, a survey was conducted $\underline{with}$ 80 primary school teachers in Jeju to investigate their recognitions in meaning of mathematical concepts in geometry and attitudes toward teaching. Most of the respondents answered they taught their students while they knew well about mathematical definitions in geometry but the respondents sometimes confused mathematical concepts of polygons and circles. Also, they were aware of problems in current mathematics textbooks which have explained figures in small topics (classes). Here, several suggestions are proposed as follows from analyzing teachers' recognitions and researches in mathematical viewpoints of definitions (promising) in geometric figures which have been adopted by current mathematics textbooks in primary schools from the seventh educational curriculum. First, when primary school students in their detailed operational stage studying figures, they tend to experience $\underline{a}$ collision between concept images acquired from activities to find out promising and concept images formed through promising. Therefore, a teaching method is required to lessen possibility of misconceptions. That is, there should be a communication method between defining conceptual definitions and Images. Second, we need to consider how geometric figures and their elements in primary school textbooks are connected with fundamental terminologies laying the foundation for geometrical definitions and more logical approaches should be adopted. Third, the consistency with studying geometric figures should be considered. Fourth, sorting activities about problems in coined words related to figures and way and time of their introductions should be emphasized. In primary schools mathematics curriculum, geometry has played a crucial role in increasing mathematical ways of thoughts. Hence, being introduced by parts from viewpoints of relational understanding should be emphasized more in textbooks and teachers should teach students after restructuring this. Mathematics teachers should help their students not only learn conceptual definitions of geometric figures in their courses well but also advance to rigid mathematical definitions. Therefore, that's why mathematics teachers should know meanings of concepts clearly and accurately.

  • Traditionally, the emphasis of the information services had been placed on the information provider's knowledge of information sources or information systems. However, in view of the increasing complexity of the information environment. and changes taking place in information professions the evaluation of the information services has callded for further research in interpersonal communication aspects of the librarian user interface especially that which links to user satisfaction. This experimental study was carried out for the purpose of exploring the implications of nonverbal behaviors in measuring user satisfaction in the light of the fact that the meaning of nonverbal clues includes more than verbal communication especially in dealing with variable barriers even though they operate at low levels of awareness. In this sense, among the wide range of nonverbal communication areas in particular kinesics, artifacts and the proximics were examined to suggest alternative model which can be applied effectively in our specific set of information work environment. Two major university libraries and two research libraries in Korea were chosen and visited for the anlysis and per each refernce/information interview the librarian's nonverbal behaviors were checked on the observer's checklist and the qustionnaires completed by the user at a time. On the basis of these data firstly, the relation of user satisfaction concerned with the librarian's nonverbal communication to user satisfaction with information services was analyzed and the possible communication barriers were investigated. In addition, the effect of training the information librarian with positive nonverbal communication skills on the user's satisfaction was analyzed in a SAS computer program in the area of kinesics. On the other hand, the effect of other nonverbal behaviors such as proximics and artifacts known very important clues to improving a complex human interaction was discussed along with their experimental results. In conclusion, it was found that most of users were not sensitive to the importance of nonverbal behaviors exposed by the information librarian, but it was proved that the ultimate user satisfaction and the satisfaction of the librarian's nonverbal behaviors are correlated positively, Moreover, nonverbal behaviors displayed by the trained librarian toward the user had a considerable effect on the user's evalution of information services compared with those by the untrained. These findings imply that in order to control the librarian's nonverbal behaviors and to help the user overcome his barriers the information librarian as a specialist needs to assure and modify willilingly his communication behavior. Without making effective use of such nonverbal communication, information librarian could not expect to meet the user's information needs either. However, when these positive nonverbal behaviors are applied it would be highly desirable to be aware of cultural and contextual differences. With regard to increasing information services success the applicable nonverbal communication model for library management and education can be suggested as below.

  • Now in order to overcome the weakest points of the rural areas of the city of Kimje and, transform them into rural cultural villages which have local governing systems suitable to new localization age and activate this plan, we selected Daesan Village as a model village which had shown a lot of potentials in the basic research and studied it dividing it into the former part and the latter part. We studied Daesan village in the former part focusing on state analysis and basic ideas and in the latter part focusing on master plan and detail planning. We can summarize the conclusion like the followings. 1. Daesan Village located 8 kilometer away from the downtown Kimje and the city of Iksan respectably has comparatively good environment of good sunny place as an open field whose surrounding configuration of the ground consists of farming lands and low hills in front and rear. It has 38 farming households in all. 2. Human environment(인문환경); the village road whose width is about 4 meters is forming a flow system forking off into three. There is a route bus which operates three times a day even into the inside of the village. The main sources of revenue are vegetables in facilities, fruits and floriculture. Their average revenue is about 10.5 million won. 3. Here in DaeSan Village a legend dealing with Teasan literally meaning a big mountain consist of th village's tradition and you can see the tombs of a very faithful son and Anwi an army general in the age of the Japanese Invasion of Korea of 1592 to 1598 inside the village. 4. 85 out of the eitire population 141 whose age are over 20 showed very positive attitudes in a questionnaire about, making the village a cultural one and its development. 5. The basic of planned ideas is to increase the revenue of the farming household by making the village a professional farming one which has a state-of the-art production facility and agricultural technique. It is to make the village the one where people can enjoy the sense of the rural life and the farmer can enjoy their lives through consumptive and consistant leisure and resting activities. 6. We are planning to make entrance space, life space, rest and sport space, and cultural space considering the characteristics of the village and the demand of the resident. We are also planning to make tile entire city of Kimje an information transmitting base in short and long term perspectives. 7. DaeSan Village was planned as a place where tradition and the future exist together. On the basis of this concept we planned future programs for Daesan Village and in the latter part of the study master plans and detail plans will be continued.the regional agricultural condition. The development permissions were only during the period of restricted to use ($1979.12{\sim}1993.11$). We propose that the authority of development permission should be given to the local autonomy government, because the local government has the knowledge of its individual agricultural conditions.

  • This study was carried out to investigate the effect of Sorbus commixta Hedl. fruit extracts on the lipid metabolism in rats. Experimental groups were divided into 3 groups; Sprague-dawley rats were fed either diets containing 1% of water extracts(WE group), 1% methanol extracts(MeOH group) and diets without extracts(Control group) during 4 weeks. Food intake, weight gain and liver weight were not shown in meaning full difference among the groups. The concentration of serum triglyceride and total cholesterol were significantly decreased in WE and MeOH group compared to control group. Serum HDL-cholesterol, phospholipids and glucose contents were slightly lower in WE and MeOH group than control group. The levels of liver triglyceride was significantly decreased in MeOH group compared to control group. The levels of total cholesterol and phospholipids in liver were significantly lower in WE and MeOH group than control group.

  • Expressionism, is as diverse as the artists invo)ved, in a very broad sense two main tendencies may be noted. The first is that of the Action painters, concerned in different ways with the gesture of the brush and the texture of the paint. It included such major artists as Arshile Gorky, Jackson Pollock, Willem De Keening, and Franz Kline. The other group consisted of the Color Field painters, concerned with the statement of an abstract sign or tranquil image in terms of a large, unified color shape or area. Here must be included Mark Rothko, Barnett Newman, Ad Rdinhardt, as well as, to a degree, Adolph Gottlieb, Robert Motherwell, and Clyf(ord Still. In this paper, 1 selected two artists Arshile Gorky and Jackson Pollock independent charac-teristics and studied the influence of their Action painting on the fabrics of modern fashion. However, it should be noted it was never the intention of the critic Harold Rosenberg, in coining this term, to imply that Action painting was a kind of athletic exercise. Nor is it true that the furious and seemingly haphazard scattering of the paint involved a completely uncontrolled, intuitive act. There is no question that, in the paintings of Jackson Pollock, Arshile Gorky and many of the other Abstract Expressionists, the element of intuition or the accidental plays a large and deliberate part; this was indeed one of the principal contributions of Abstract Expressionism which had found its own inspiration in surrealism's 'psychic automaton'. However, nothing that an experienced and accomplished artist does can be completely accidental. Aside from their intrinsic quality, the spun-out skeins of poured pigments contributed other elements that changed the course of modern painting. There was the concept of the all-over painting, the painting seemingly without beginning or end, extending to the very limits of the canvas and implying an extension even beyond. The feeling of absorption or participation is heightened by the ambiguity of the picture space. The colors and lines, although never punctur-ing deep perspective holes in the surface, still create an illusion of continuous movement, a billowing, a surging back and forth, within a limited depth. To study the influence of Abstract Expressionism on the fabric of modern fashion, 1 selected and examined four fashion magazines: Collezioni published in France, Bazaar in Italy, Gap in Japan and Vogue in the U.S.a. froim January 1989 to June 1991. As a result of this review I found that some fabrics used in modern clothing are printed in a dripping, pouring and splashing style without any meaning or form. Slides included in the presentation show that modern fabrics which are printed in such a style were influenced by Abstract Expressionism. The slides also show that these abstract prints are well suited to modern fashion design.

  • Objectives: This study was performed to analyze the toxicity and to find the lethal dose of the test substance Water-soluble Carthami-flos pharmacopuncture (WCF) when used as a single intravenous-dose in 6-week-old, male and female Sprague-Dawley rats. Methods: The experiment was conducted at Biotoxtech according to Good Laboratory Practices. 20 female and 20 male Spague-Dawley rats were divided into 4 groups of 5 female and 5 male animals per group. The rats in the three experimental groups received single intravenous injections with 0.125-mL, 0.25-mL and 0.5-mL/animal doses of WCF, Groups 2, 3, and 4, respectively, and the control group, Group 1, received a single intravenous injection with a 0.5-mL dose of normal saline. Clinical signs were observed and body weight measurements were carried out for 14 days following the injections. At the end of the observation period, hematology, clinical chemistry, histopathological tests and necropsy were performed on the injected parts. Results: No deaths occurred in any of the groups. Also, no significant changes in body weight, hematological parameters or clinical chemistry test results between the control group and the experimental groups were observed. Visual inspection after necropsy showed no abnormalities. Histopathological tests on the injected parts showed no significant differences, except for Group 1 females; however, the result was spontaneous generation and had no toxicological meaning because it was not dose-dependent. Therefore, this study showed that WCF had no effect on the injected parts in terms of clinical signs, body weight, hematology, clinical chemistry, and necropsy. Conclusion: As a result of single intravenous-dose tests of the test substance WCF in 4 groups of rats, the lethal dose for both males and females exceeded 0.5 mL/animal. Therefore, WCF is a relatively safe pharmacopuncture that can be used for treatment, but further studies should be performed.

  • This study investigated small group processes in paired think-aloud problem solving. Two high school chemistry classes were assigned to St-SL group (using Strategy-Solve Listener) and SL group (Solver Listener), and their small-group behaviors were audio/video taped. Verbal behaviors of solver and listener in respect to 4 problem-solving stages and performance levels at each stage were analyzed. At the understanding stage, listeners in the St-SL group exhibited more behaviors of agreement to solver's understanding processes about given and goal of problem. As regards recalling a related law at the planning stage, solvers in the St-SL group exhibited more behaviors of modification based on listener's questions or pointing out. These verbal interactions seemed to have a positive effect on students' deriving the physical quantity with the proper laws. Few in both SL and St-SL groups exhibited the behaviors regarding setting up subgoals. No verbal behavior was observed in the SL group at the reviewing stage, and solvers in the St-SL group tended to ask for listener's agreement. However, only few performed the strategy explaining the meaning of answer at the molecular level correctly through the interactions. The St-SL group perceived that the understanding stage was the most helpful and that the planning or reviewing stages were difficult to apply.
