The purpose of this paper was to introduce sociocultural theory which is a different epistemological perspective from constructivism and to understand the sociocultural theory in a systemic way by providing four specific criteria for a sociocultural theory from the analysis of Vygotsky's ideas. The four criteria are the followings: first, the origin of learning is not at the individual level, but at the social. Second, Learning takes place in a sociocultural framework through ZPD and there exists the stage of pseudo concept before it gets to a true concept. Third, a clear focus on action, especially mediated action, and the concept of psychological tools should be discussed in the boundary of a sociocultural theory. Fourth, actors in a learning process are not an individual child alone. In consequence, the role of adults, particularly teachers, are significant in a child's learning, and this fact provides a great potential for the active role of teachers in the students' learning of mathematics from the sociocultural perspective.

This study analyzed the evolutionary content in 13 textbooks developed from the first to the 6th high school biology curriculum, The content analysis of textbooks, which were delineated nine component, was performed on the 80 evolutionary categories, According to the result, the proportion of the total evolutionary content in textbook increased from the textbooks developed by the Ist curriculum to the textbooks developed by the 6th curriculum, but the proportion of 'main narrative' in total evolutionary content was gradually decreased. It also showed that biology curriculum and points of view of textbook writers influenced on the proportion of evolutionary contents. On the whole, the topics of analysed textbooks exhibit insufficient diversity, Any categories- 'group selection', 'gene selection', 'gaps in fossil record', 'co-evolution', 'punctuated equilibrium', 'mosaic evolution', 'place of labor in human evolution', 'human race differentiation', 'criticism of "ontogeny recapitulates phylogeny", and 'human activities affecting evolution' - were not treated and others - 'theory of neutralism', 'theories of major episodes(excepting extinctions) found in the geologic time scale', 'sympatric speciation', 'clinal and area-effect speciation', 'polyploidy and evolution', 'gradualism' and 'evolution and origin of mammals' - were treated very lightly, the most emphasized topic was 'phylogeny in general' and 'formation of precells', 'miscellaneous' in the order of emphasis. 'Theory of natural selection' was lightly treated as just one of evolutionary theory though it should be emphasized as major theme of evolution. Also, the law of recapitulation, of which biologists doubt the validity, was discussed as an evidence of evolution in some textbooks. And the agents of genetic equilibrium disruption like genetic drift and migration were treated as of little importance. On the basis of above result, it was suggested that the textbook writers introduced the more meaningful evolutionary topics focused the theory of natural selection in explanation of evolution and evolution theory.

This treatise is written in order to solve the important contradiction between the two theories; in oriental medicine psychological function is responsible for heart, but in western one it is responsible for brain. So we take the methods of studying in the aspects of morphological characteristics(MC) and visceral manifestation theory(VMT, 藏象論) and others about two organs-heart and brain. Brain(頭腦) is preferred to understand as a structure which is manifesting mental activity of heart. So the brain can be named with external heart(外心) corresponding to the relation of kidney(外 and external kidney. Saying conversely, the nutritional foundation of the mental function is the blood of heart, but the enlightening and insightful features of mentality make it's own residence move to the organ in the uppermost and positive site, that is head. And the close relationships on mental functions between heart and brain were discussed in various aspects, like investigation on east and west etymological literature, or Jiu gong and Taoist theory as well as Me and VMT, These understandings can make us know about the pathology of brain by itself. It has deep relations with heart fire and heart blood and kidney essence, and gastrointestinal function and liver with lung additionally. In another point, it makes the highly complicated psychological functions to be explained free from body relatively, and so can do a role in the complement of the strict 5 viscera theory.

In this study, partial drilled shafts (Bottom Cast-in-place Concrete pile) were applied to the pilot test site to ensure the bearing capacity; we used the skin friction force in the IGM to analyze the feasibility of the application of IGM theory. The soil characteristics were analyzed in cohesive, non-smear, and smooth conditions for the application of the IGM theory via geotechnical investigation and measurement of the disturbance and surface roughness. Static load and load transfer tests were conducted to calculate the allowable bearing capacity and the skin friction force by depth. The skin friction force increased with increase in the depth and standard settlement, showing a very high correlation. In addition, because the unconfined strength ($q_u$), which is the most important parameter in the cohesive IGM, cannot be measured in a weathered granite area, the static load and load transfer test results and the N value were used to obtain $q_u$.

Since Korea open her ports to the West, she had undergone a great change under the alien influences both on the macro-social and micro-social aspects. This study aims to review the korean housing, corresponding with the everyday life, during the period of transition between the 1876 - 1910 and to interpret its process of modernization and the meaning of modernity. With regards to understand the holistic human relationship and place pf living through history, this study takes the Nobert Elias' Civilization Theory as a theoretical basis. References were therefore, made to various records of foreign missionary at the time, with respect not only to macro sociological changes but also to changes of everyday life. It is of course to take physical and structural aspects of housing architecture into consideration. These works, thus, led to presuming the housing culture of said period. In order to investigate modern character of korean housing, distinctively represented by spatial structure, considerations were made to various architectural examples according to the social and residential status both in urban and rural area. As a results, this paper came to the remarks as follows; 1. It is understood, that the process of modernization is a part of the process of civilization as synthetic process. It is integrated with the change of socio-cultural aspects and everyday life. 2. Korean housing in the said period shows various different residential status and grade of civilization according to the social status as well as economical status. Modern housing was not in general yet. 3. Housing for high classes and middle classes in Seoul shows a tendency of assimilation and imitation after western model. But some examples within the housing of high classes represent its own modernity, that is based on the rationalism and equalization 4. In the housing of lower classes, it was very far from the benefits of civilization. It could analogize from the immature control of disgrace, from undevelopment of individual territory and from uncultivation of rationality in the housing space.

${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$(${\ulcorner}$醫方類聚${\lrcorner}$ is a medical book which classifies and edits the existing books. First of all, it is not until finishing the study of reference books that we can study the ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$ in earnest. We did not take traditional non-systematic methods to study the reference books of ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$ systematically. We investigated the title of 'reference book's name' as a reference book and did not investigate re-reference books. The number of reference books are one hundred forty-two volumes. Most of the reference books are medical books; some books are about Taoism and Buddhism. The title of the reference books are given a name by various methods. But these methods have a lot of problems. First, the same title book misapply an alias, the original text name and an abbreviated name. Second, a chapter name misapplies reference books. Third, reference books misapplies a chapter name. Forth, the writer and book name misapplies reference books and so on. From quotation collection about ${\ulcorner}$Classified Collection of Medical Prescriptions${\lrcorner}$'s characteristic point fellows below in three kinds. First, it emphasizes medical therapy. Second, most of Song(宋) period, Geum Yuan(金 元) period of China reference books take place in here. During this period it had accepted studying theory from clinical accumulation and the result of re-clinical studies reception based on theory research, and also had accepted Geum Yuan's expansive theory. Third, by adding technical books of a professional assortment, it has raised its profession of division.

This study reviews geographical research trends on 'New industrial agglomeration' in Korea and recommends research issues for further studies. Recent studies on industrial agglomeration region have typically concentrated on empirical case studies from new 'perspectives'. As a result, the establishment and theorizing of frameworks for analysis on industrial agglomeration have been given too little attention. To solve this problem research should be conducted to develop frameworks for analysis integrating noneconomic factors and existing economic factors, a strategy emphasized in new industrial agglomeration theory. By doing so, research investigating viability mechanism and generalization will be invigorated. Meanwhile, research focused excessively on social and cultural conditions of region-related networks between actors in economic space at specific scales should be excluded. In addition, academic research on vitalizing industrial agglomeration region, such as cluster policy, should be strengthened. In order to conduct these research objectives effectively, it is necessary to vitalize overall understanding among researchers of industrial agglomeration and provide a place for collaborative learning.

The effect of passing pedestrians'characteristics on locational goodwill was empirically modeled and tested. The theoretical basis for the study was central place theory, bid rent and, agglomeration theory, and demand externality theory. The data included information on goodwill, retail rents and passing pedestrians' characteristics in 100 retail trade areas in Seoul. The empirical model was tested with the sample of 1,307 retail units in Seoul, South Korea. The data set was analyzed with the Classification and Regression Tree software. As the results, using the regression tree method, the variables does affect locational goodwill in the each retail trade area were the volume of pedestrians around 2:00 pm on weekdays, volume of pedestrians around 4:00 pm on weekdays, and volume of pedestrians around 8:00 pm on weekdays. In summary, not only the economic base in the retail trade area but also the volume of passing pedestrians should be considered to determine the locational goodwill.

Performance and productivity of robot manipulator can be improved by increasing its working speed and extending its link length. But heavy weght of the commercial robot links, considered as "rigid body", limits its mazimum working speed and the weght of the links can be reduced for high speed operation. But this light-weight link or long link for special use cannot be consideredas "rigid" structure and vibration of the link due to its flexibility causes errors in end-effector position and orientation. Thus the elastic behaviro of the flexible link should be taken care of for increasing work speed and getting smaller error of end-effector position. In this paper, the fuzzy control theory is selected to design the controller which controlos the joint positions of the robot manipulator and suppress the vibration of flexible link. In the forst place, for the 1 DOF flexible link system, the fuzzy control theory is implemented. The contdroller for the 1 DOF flexible link system is designed. Experimental research is carried out to examine the controllability and the validity of the fuzzy control theory based controller. Next, using the extended desing schemes for the case of the 1 DOF flexible link system and usign the experimental phenomena of the 3 DOF flexible link system, the fuzzy controller for the 3 DOF flexible link system is desinged and experimented.ed and experimented.

In the recent years, with a purpose to provide visual and psychological stability to patients and hospital users, Affordance design theory based on perceptual psychological thought has been applied as hospital design. In the past, hospital service design was focused on but Affordance design theory focuses on the patients' experience and methodological research on . The characteristics of the application of Affordance design in the case of patients' experience and service point is as follows:- Firstly, Affordance design is applied when the objective of the patient's experience and the functionality of the object are combined. In other words, affordance design is a condition that arises when encounter between service contact point and patients' experience takes place. Secondly, In the field of Hospital service design, Affordance concepts in and its application can be divided on the functions of experience, cognition and sense following the application of Affordance concepts in Hospital service design. Thirdly, Affordance design method sets meaning of the action received through information provided by morphological features. The condition and surrounding has to be designed in a way that it can induce active behavior of the patient. This study has significance as it has been studied from the perspectives of Affordance theory of design psychology in addition to the physical environment of the hospital, the point of interaction between the hospital and patient, along with the elements of experience design. This study proposes the necessity of analytical study in the field of service design implementation considering various stakeholders in the service contact points of small and medium hospitals in Korea. Furthermore, study of the application of Affordance design can be complemented by reflecting the size of hospitals, the characteristics of specialties, and the specific service environment of each hospital can also be conducted.
