  • The purpose of this study is to analyze the determinants of start-ups by industry based on the theoretical background of entrepreneurship. For this purpose, regional industrial structure and local labor market structure are considered in order to focus on regional factors in addition to economic factors, income factors, and technological innovation factors. As an analyzed result, three theories of entrepreneurship generally agree with the determinants of industry - specific entrepreneurship. During the economic recession, the number of start-ups has increased. The intra-regional consumption and the local government expenditure per capita have also positive effects on the start-up. The incubation center has a positive effect on the start - up in the manufacturing sector. Therefore, the academic-industrial leading various incubation facilities should be activated in addition to the central or local government leading incubation centers, which is a part of the policy to support start-ups of central and local governments. In addition, population growth is a very important factor in terms of potential demand creation, and the characteristics of regional industrial structure and the effect of human capital within the region differ by industry. In the case of the manufacturing industry, the accumulation effect positively influences the start-up of the industry. In other service industries, the human capital variable had the greatest effect on the start-up when all other conditions are constant.

  • The needs for ecological engineering, which can design ecosystems that integrate human society and their natural environment for the benefit of both, has increased. The Korean Society of Ecology and Infrastructure Engineering (KSEIE) was established for this purpose and has contributed to the research and development of theories and technologies in related fields. However, the current state of educational services and contents of ecological engineering is still needed to be standardized and systematized. In this paper, we outlined the trends of ecological engineering education at international and domestic levels and proposed a sample services and curriculum, brought from the discussions and suggestions made during the forum, Founding the Education for Ecological Engineering, held by the KSEIE. Education of ecological engineering can nurture people who can design and manage ecosystems for the benefits of human and natural society and can restore ecosystems disturbed artificially. The services and curriculum have to meet and cover the challenges facing the future of ecological engineering; a. the ethical interpretation of the balance between human and nature, b. developing and strengthening its relationship with other scientific disciplines and societies - business, policy, education, and practitioners, c. identify and fuse the key ecological engineering principles into other discipline. We proposed a three layers curriculum system, basic (mathematics, physics, chemistry, biology, etc.), core (ecology, hydrology, engineering, etc.), and advanced subjects. The first two can belong to an undergraduate program and the last two can be put into graduate program. The selection of subjects is according to the purpose and needs of the major.

  • The attempts to explain the criterion of art criticism can be divided into three directions. The first is that there is a universal criterion of criticism. The second is that criticism is a subjective impression of each critic. Therefore, there is no universal criterion beyond a subjective impression. The third is that denies both claims. It tries to and the objective criterion which is neither universal nor subjective. In this paper, I will see how John Dewey criticizes the first two theories and holds the third theory. Dewey's denial of the first theory can be seen in his view of the judical criticism. The judical criticism claims that art criticism can be made on the universal criterion, as judical decision can be made on the general rule supposed to be applicable to all cases. But Dewey claims that the judical criticism cannot explain what makes the artist the 'masters'. Defining art as an experience, Dewey claims that art is a process of doing and undergoing, and that art is essentially an interactive activity between men and his environment As environment changes, the experience of the environment also changes. So art should accept the possibility of new experience. But, since the judical criticism advocates of the universal criterion which cannot allow the changeability, Dewey denies it. On the other hand, Dewey's denial of the second theory can be seen in his view of the impressionist criticism. The impressionist criticism claims that criticism is to clarify the impression which is consisted of feeling and imagery the art object evokes. To this claim, Dewey replies that to clarify an impression is to analyze it, and analysis can proceed only by going beyond the impression to the judgement. As we have seen so far, Dewey has denied the judical criticism that there is a universal criterion supposed to be applicable to all criticism. He has also denied the impressionist criticism that there are only subjective responses to the art object, and hence that there is no criterion of criticism at all. For Dewey, these two criticism are based on the same false assumption of the criterion, although their conclusions are different from each other. Both the judical and impressionist criticism failed to realize the difference between the meaning of the criterion as applied in measurement and as used in criticism. Criticizing of these two views of criticism, Dewey claims that there is an objective criterion which is neither universal nor subjective. Art criticism is objective in tv#o senses, i. e., in the first sense that it can be judged by the properties of the art object and in the second sense that it can be verified by the communities of the critics.

  • 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.

  • The purpose of this study was to analyze pre-service teachers' reflective discussion on their practical work-based teaching by focusing on the components of instruction and the connectivity of discussion. Eight after-class discussions were recorded and transcribed, and finally analyzed in terms of theoretically driven categories such as aims, teacher knowledge and learner response which also respectively reflect the actual flow of planning, implementation and evaluation of the teaching practice. The result showed that in their discussion about students, conceptual understanding and scientific skill components were most emphasized, while teaching method and strategy were most frequently addressed in the discussion about teacher knowledge. But this also revealed problems in their discussions such as the lack of discussion about inquiry and student interest, difficulties in clarifying theoretical terms and the lack of discussion about instructional models and theories. Meanwhile, pre-service teachers' discussions were limited in terms of connectivity between the components of instruction, meaning that their discussion tended to deal with each component separately rather than occurred in connection with each other. Furthermore, when connections were made during the discussion, only few components of instruction appeared. Based on this result, the paper suggests the need to develop tools to facilitate effective reflection in ways that incorporate various components of instruction and enhance connectivity between the components and between the instructions.

  • In the universities of U.S.A., Criminal Justice is the interdisciplinary study of the institutions and policies that constitute the criminal justice system, as well as theories of human behavior and philosophies of justice related to the maintenance of social order, the control of crime, and the achievement of a just society. There are 103 American Universities have Criminal Justice department and they provide about 180 differents courses as a pre-requisition or optional subject in the major. The most 10 courses that those colleges adopted are Introduction to Criminal Justice, Criminal Law, Criminology, Criminal Procedures, Research Methods in Criminal Justice, Criminal Investigation, Juvenile Justice, Terrorism, Ethical Issues in Criminal Justice, Introduction to Psychology or Introduction to Sociology. Also, 10 fields more important in the major if we group together similar courses those are Criminal Justice and Procedures Sequences, Law, Justice and corrections, Theory and Methods Sequences, Homelend Security and Security Operations, Forensics and Cybercrime, Management and Administration, Police, Race and Ethnicity, General Requirements, Other Social Science Fields. The combined degree program leading to Bachelor of Arts Degree in Criminal Justice and Master in Public Administration provides a concentration in criminal justice, management, administration, and leadership. They have big different courses between USA and Korea event though they have similar educative goal and way of approach to the target in the major.

  • The study attempts to analyze the trends of study related with oriental nursing. This article reviewed 81 researches on oriental nursing from 1985 to July 2000, by examining them according to the articles' characteristics, sources by publication period, research design, nursing intervention effect of experimental study and concept, and content of literature review. The findings of the analysis can be summarized as follows; 1. The number of studies related with oriental nursing has progressively increased by year from 1985, and that of articles was the highest during the period between 1995 to 1999. Since the 1990s, the number of articles including thesis and dissertation increased, and a third of subject articles were thesis among them. 2. The majority of research design were survey and correlational studies, and most of them were published in the 1990s. Literature review articles also occupied a certain portion, and most of them were published after 1995. In addition, the research design of dissertation revealed in various types. 3. Nursing intervention used in the experimental study was Dan Jeon Breathing, San-Yin-Jiao (SP-6) Pressure, Percutanous Electrical Nerve Stimulation, Guided Imagery, Diet for Sasang Constitution, Yoga Exercise, Qigong Exercise, Meridian Massage, Bed Exercise Program, Health Contract and Structured Rehabilitation Education. Among the study subjects, patients with chronic illness were at the highest rate, and the most nursing intervention effects presented physiological effect, activities of daily living and relieving pain. In most studies, the affirmative effect proved. 4. The key concept of literature review articles is energy, oriental nursing, health promotion, oriental medicine management of illness and etc. Being important concepts to understand oriental nursing, they confirm similar perspective of oriental medicine and nursing and show simultaneously the importance of nursing considered into the cultural perspective. The summary of the above results shows a tendency that the thesis and dissertation have been relatively considered with various research designs, while the others have focused on literature review. Especially, experimental study proved affirmative effect through various experimental treatment of nursing intervention related with oriental medicine. Besides in the literature review, inquiry of theories and practical perspective, which is necessary for the establishment of oriental nursing, was introduced. However, for the establishment of oriental nursing, more studies are to be required along with development of nursing intervention related with health promotion.

  • Recent years have seen an explosion of interest in interactive agents motivating human learners to engage in edutainment systems which are designed to be entertaining and educational at the same time. Especially, work on socio-emotional processes has focus on understanding of human's social behavior in training and entertainment a applications. In contrast with work on social emotion, where research groups have developed detailed models of emotional processes, models of personality have emphasized shallow surface behavior. Here, we build on computational appraisal models of emotion to better characterize dispositional differences in how people come to understand social situations. Known as explanatory style, this dispositional factor plays a key role in social interactions and certain socio-emotional disorders, such as depression. Building on appraisal and attribution theories, we model key conceptual variables underlying the explanatory style, and enable agents to exhibit different explanatory tendencies with respect to their personalities. Furthermore, we developed an interactive AR agent based on our framework and applied it into an interactive teaming system that allows participants to explore individual differences in the explanation of social events, with the goal of encouraging the development of perspective laking and emotion-regulatory skills.

  • This study reviews the development and change of main entry principle in German cataloging codes, with special emphasis on RAK. With rerard to the functions of catalog, comparison between the traditional title main entry in the Orient and author main entry in the West has been made. The analysis confirms in this study that various criteria in choice of the entries in RAK have been adopted. In case of works where the persons who have played different roles in the works are named on the title page, as well as related works and works of mixed responsibility, the criteria of entry determination are complex and time consuming process and have no absolute value. And there are also various kinds of problems in corporate entries including confirmation of originator(Urheber), choice of either the territorial authority corncerned or corporate bodies as an entry depending on the nature of the publications, and a unique bibliographical situation of treaties. This means the code is absence of absolute value in selecting entries, and this results in adoption of main entry principle which has lost its significance for the purpose of cataloging. With emergence of the ISBD and actualization of automated cataloging, morever, all entries are equal as points of access. It would eliminate the need for personal judgements required in choice of main entry by the present code. In doing so, it would bring uniformity and standardization to cataloging practice. In direct approach to works, title entry is more developed finding device than author entry in cataloging theories. Thus introduction of unit card system beginning with title which is adopted in KCR3 would be desirable, the complicated rules for the choice of entry could be abandoned from cataloging codes. Most of the user studies show that catalog users have placed higher value on the title entry as a finding device and each entry is equal as access points through unit entry. This means that choice of a given entry as a main entry is unnecessary in cataloging codes. Title entry would be a rather simple standard and direct approach for works. This study proves that the traditional title entry of Korea is superior to author main entry in the Western world in cataloging theory. Thus recommendation to be made is that abandonment of author main entry from cataloging codes should be considered in the future.

  • We study free vibration analysis of sigmoid functionally graded materials(S-FGM) nano-scale plates, using a nonlocal elasticity theory of Eringen in this paper. This theory has ability to capture the both small scale effects and sigmoid function in terms of the volume fraction of the constituents for material properties through the plate thickness. Numerical solutions of S-FGM nano-scale plate are presented using this theory to illustrate the effect of nonlocal theory on natural frequency of the S-FGM nano-scale plates. The relations between nonlocal and local theories are discussed by numerical results. Further, effects of (i) power law index (ii) nonlocal parameters, (iii) elastic modulus ratio and (iv) thickness and aspect ratios on nondimensional frequencies are investigated. In order to validate the present solutions, the reference solutions are compared and discussed. The results of S-FGM nano-scale plates using the nonlocal theory may be the benchmark test for the free vibration analysis.
