  • A quantitative method was suggested for estimating damages in fishery production due to the diffusion and deposition of suspended silt and clay by various construction processes in tidal flat fishing grounds. Marine populations are maintained through the process of spawning, growth, recruitment, natural death and death by fishing each year. All of the year classes of the population in a fishery ground could be affected when damages occur by human activities such as land filling or reclamation. The propose of this study is to calculate damages in terms of fishery production using a quantitative population dynamic method. If the maximum age in the population is $X_\lambda,$ the starting year of damage is $t_s,$ and the ending year of damage is $t_e,$ the number of year classes damaged is $t_{s-n\lambda}-t_e,$ Many year classes present in the year $t_s,$ and so if damages occur, they Influence all the year classes which are present in the population. Damaged year classes in year $t_e$ would still be in the population until the year $t_{e+n\lambda}$, where $n_{\lambda}$ is the oldest age class. If the expected yield of a year class is constant, the total yield from year classes in the fishing ground during the construction periods can be calculated as follows: $Y_\Phi=[(t_e-t_s+1)+n_c]{\cdot}Y_E+\sum\limits^{n_\lambda-n_c}_{l=1}\;\sum\limits^{n_\lambda-n_c}_{l=i}\;Y_{n_c+i}$ This method was applied for damage estimation in the production of Ruditapes philippinarum in a tidal flat fishing ground.

  • This study analyzes the development of technological infrastructure(TI) and technological infrastructure policy(TIP) to enhance the technological capabilities of small and mid-sized manufacturing enterprises(SMEs) in the U.S. and Korea in terms of the technological system(TS) concept, which is composed of technological infrastructure, industrial organization, and institutional infrastructure. In order to analyze the internal dynamics of the system, such as incentive mechanisms, the interaction among economic actors, and the policy implementation process, we compare the MEP(Manufacturing Extension Partnership) system of the U.S. and the Joong-Jin-Gong system of Korea. Among many similarities, contrasts, and insights from each country's effort to construct TI and TS, the main findings are as follows. (1) Both the MEP system and the Joong-Jin-Cong system are TI-led or government-led type TS. However, the nation-wide picture is different: in the U.S., most TSs including the MEP system., are classified as TI-led type; in Korea, many TI-assisted or private sector-led TSs have been developed since the early 1960s. (2) the MEP system, as a representative case of the U.S., is less stable than the Joong-Jin-Gong system of Korea in terms of financing and political cycle. (3) The MEP system is a more complex and cooperative network than the Joong-Jin-Gong system. NIST, as a critical mass, generates the system, bridges various institutions, and influences the development of the system by providing funding. (4) Regarding TI components, TSs in both countries focus on utilizing off-the-shelf technologies rather than advanced technologies. However, the direction of movement is different: in the U.S., TSs have come to emphasize existing technologies to counterbalance an innovation system that has been highly focused toward new technologies; in Korea, TSs have been moving from focusing on a higher diffusion rate of imported process technologies to stressing new technology development. (5) Personnel and staffing, embodying technological capability, is an important concern in both countries. But the human capital infrastructure of the U.S. system is more efficient and industry-oriented than that of the Korean system due to a more flexible labor market. (6) While the U.S. has a strong tradition of state and local autonomy in constructing TI and TS to fit SMEs's specific need, Korea has a centralized and bureaucratically-led policy implementation process.

  • Some spread-effects and their dynamics accruing to regional community from the new location of large firms would be an interesting theme in economic geography On the assumption that all firms not only should. have cooperative relations with their regional communities but also try to realize such cooperations in case of locating their facilities, some rationale for their philanthropic activities will be discussed in this paper. The focus of this paper is on the community contributions or philanthropy which are executed as the non-profit motivated activities of firms. Why and how should firms respond to the growing requirements of their communities, and what type of philanthropic activities could be good for their social behavioral contexts are the questions to be solved in this study. It is possible to get some guidelines of a firm's philanthropy through the comparisons on the practices in the three largest firm.5: Kodak. Dupont, and POSCO.

  • This study investigates how elementary students used cognitive-emotional rebuttals in the context of modeling activities, especially on how their emotional and cognitive processes lead them to use rebuttals in terms of epistemic affect. Twenty-five fifth grade elementary students participated in the study as part of their science class. During the course of their sixth periods, students constructed a human respiratory system model through continuous discussion. The research results showed that elementary students used an elaboration-oriented rebuttal, a defence-oriented rebuttal, and a blame-oriented rebuttal in their modeling activity. The elaboration-oriented rebuttal interspersed with negative epistemic affect was used to elaborate on a student's explanation, and a negative epistemic affect was elicited from their cognitive discrepancy. On the other hand, defence-oriented rebuttal and blame-oriented rebuttal entangled with negative epistemic affect were used to defeat the students rather than help rigor evaluation of students' explanation, and the negative epistemic affect was elicited from the other students' undesirable behavior. These results suggest that students' rebuttals can be elicited by epistemic dynamics related to the epistemic affect. The study shows that if negative epistemic affect were elicited from the other students' naive or false explanations, such an emotion is natural in terms of model construction, and the model can be further developed through the acceptance of the elaboration-oriented rebuttals by students' emotion regulation. In addition, we suggest that negative emotions aroused from the worsening of relationships during small group modeling activities are difficult to regulate and can have negative effects on students' cooperative model construction.

  • In order to investigate the structure and dynamics of atatic poly (vinyl alcohol) (PVA)/water system, laser light scattering experiment has been done in the semi-dilute concentration regime at $25^{\circ}C$. The scattering intensity I(q) can be analyzed with the fractal equation of $I(q){\sim}q^{-m}$ instead of Onstein-Zernike type equation. The fractal dimensionality m was found to be constant after reaching the plateau value of $m=2.6{\pm}0.3$ above C=3wt%. The time correlation function of dynamic light scattering has always two different modes such as fast mode and slow one. The cooperative diffusion of fast mode showed concentration independence contrary 4o the reptation theory's concentration dependent exponent of 3/4. The slow mode can be interpreted as the motion of large scale heterogeneities and its strong concentration dependence is apparent with a large negative exponent of -3.0. It is considered that the stereo-regular arrangement with four successive meso units of -OH plays as a key role in forming such heterogeneity.

  • This paper aims to analyze the process of the evolution of Gumi electronics industrial cluster and to understand the role of governments for local industrial dynamics. Gumi was a typical satellite platform type new industrial district up to mid-1990s. At that time, Gumi industrial park was the agglomeration of branch plants headquartered in Capital Region with weak local linkages. During the last two decades, however, Gumi has evolved to an electronics industrial cluster with considerable local interfirm linkages and innovation activities of SMEs. Recognizing government industrial policies is critical in understanding the process of the evolution of Gumi electronics cluster. At the early stage, the state was the developer and locator of business activities within the confines of the Gumi industrial park. In recent years, central government's innovative cluster policy contributed to strengthening networks among firms, universities, and research centers to form local innovation networks as well as networks between large branch plants and SMEs. Gumi city and Gyungsangbuk-do promoted innovative activities of SMEs through the supports of cooperative networks between universities and SMEs. The increasing roles of SMEs and local governments in addition to the large branch plants and the central government have become the basis of the evolution of industrial cluster in Gumi.

  • The purpose of this paper is to highlight the importance of conflict management by local government by explaining a peculiar case of Namyangju city's construction project of landfill site for incineration remnants. Policy stage and internal dynamics of conflict between city and opposition group of local residents are used as major tools of case observation. From this analysis, this study finds that the conflict management effort of local government is critical to bring a success of a public policy. The local government needs to assess possible sources of conflict, and to prepare reasonable solutions through sincere communication with local residents. Also we need to reconsider the concept of administrative efficiency. Sometimes "slow" is better than "fast". Authoritative and hasty policy process may face unexpected obstacles, then consume more time to fulfill the policy goals. It means that the local government needs to spend more time for policy formulation. It also shows the importance of democratic process in reaching a public policy decision. In conclusion, this study confirms that the cooperative relationship between local government and residents, so-called governance, is the key to the success of public policy.

  • To understand the structure and dynamics of different forms of learning, whether incidental or conscious, we have to study them as parts or aspects of concrete historical activities with specifiable contexts. This realization is more embodied in apprenticeship learning situations of the student teachers. In this perspective, this paper aims to understand the student teachers' experience on geography teaching as a participant observer in the secondary schools. The 9 student teachers during the teaching internship have written their 38 journals, which was quality analysed to find out key concepts for the purpose of this research. Major conclusions are suggested below as follows. First, the most student teachers were experienced in geography teaching in the secondary schools through the 2-weeks practice teaching. Second, in the positive perspective, student teachers observed on that teachers would teaching well interact with student and experienced teachers would settle down to student's studies. Third, in the negative perspective, student teachers observed on that teachers lecture with only text, and cooperative learning by student presentation in the geography class. Finally, In third person perspective, there is no students' or teachers' productive questions in the whole-class conversation. In addition to that the most mentor teachers lecture do all of the talking in class. In effect these student teachers' experiences, especially 'reality of the geography teaching' and 'practical knowledge of the novice mentor teachers or experienced mentor teachers', either reinforce or modify understanding about the geography teaching practices.

  • This Paper aims to elaborate on the origin of thinking mind. And this is a cooperative project between philosophy and neuroscience and brain science. I have written this paper in admiration for the achievements of twentieth century neuroscience and brain science, and out of desire to assist the subject in future. Much of the history of modern philosophy, from Descartes and Kant forward, consists of failed models of brain. As Edward O. Wilson precisely said, the shortcoming is not the fault of the philosophers, who have doggedly pushed their methods to the limit, but a straightforward consequence of the biological evolution of the brain. Guiding that investigation down pathways that will illuminate brain research is a task of neuroscience and brain science. Investigating logical relations among concepts is a philosophical task. If we are to understand the neural structures and dynamics that make perception, thought, intentional behaviour possible, clarity about these concepts and categories and their relations is essential. Hence our joint venture of philosophy and science. Sure, it is human beings that perceives, not parts of its brain. And it is human beings that who think and reason, not their brain. But the brain and its activities make it possible for human beings-not for it-to perceive and think, to feel emotions, and to form and pursue projects. Thus We try to investigate and reveal the origin of thinking mind as follow: 1) The difference between chimpanzee and human beings 2) brain and mind 3) the origin of thinking 4) the wisdom of nature.

Study on true nature of the Fung(風) and that of application to the medicine (풍(風)의 본질(本質)과 의학(醫學)에서의 운용(運用)에 관(關)한 고찰(考察))

  • Up to now, after I had examined the relation between the origin of Fung(風) and Gi(氣) and the mean of Fung in medical science, I obtained the conclusion being as follows. The first, Fung(風) means a flux of Gi(氣) and Gi shows the process by virtue of the form of Fung, namely, Fung means motion of Gi. In other words, it is flow of power. Accordingly, the process of all power can give a name Fung. The second, Samul(事物) ceaselessly interchange with the external world to sustain the existence and life of themselves. And they make a adequate confrontation against the pressure of the outside. This the motive power of life action(生命活動) is Gi and shows its the process on the strength of Fung. The third, Samul(事物) incessantly releases power which it has to the outside. Power released to the outside forms the territory of the established power in the environment of them and keep up their substance(實體) in the space time(時空). It can be name Fung because the field(場) of this power incessantly flows. The fourth, man operates life on the ground of the creation of his own vigor(生氣) for himself as the life body(生命體) of the independence and self-support. The occurence of this vigor and the adjustment process(調節作用) is supervised by Gan(肝). That is to say, Gan plays a role to regulate and manage the process of Fung or the action of vigor with Fung-Zang(風臟). The fifth, because the Gi-Gi adjustment process(氣機調節作用) of Gan is the same as the process of Fung, Fung that operates the cause of a disease is attributed to the disharmony of the process of the human body Gi-Gi. Therefore, the generating pathological change is attributed to the extraordinary of the function by the incongruity of Gi-Gi(氣機) or the disorder of the direct motion of Gi-Hyul(氣血). Because the incongruity of this Gi-Gi of the human body gives rise to the abnormal of Zung-Gi(正氣) in the human body properly cannot cope with the invasion of 'Oi-Sa(外邪). Furthermore, Fung serves as the mediation body of the invasion of other Sa-Gi(邪氣) because of its dynamics, By virtue of this reason, Fung is named the head of all disease. And because the incongruity of the Gi-Gi has each other form according to Zang-Bu(臟腑), Kyung-Lak(經絡), and a region, the symptoms of a disease appear differently in line with them as well. The sixth, Fung-byung(風病) is approximately separated Zung-Fung(中風) and Fung-byung(猍義의 風病). Zung-fung and Fung-byung is to be attributed to the major invasion of each Jung-gi and Fung-sa(正氣와 風邪). But these two kinds stir up the problem to the direct motion of Gi-hyul(氣血) and the harmony of Gi-Gi in the human body. When one cures it, therefore, Zung-fung has to rectify Gi-Gi and the circulation of Gi-hyul on the basis of the supplement of Jung-gi(正氣) and Fung-byung must make the harmony of Gi-Gi with the Gu-fung(驅風). -Go-gi(調氣), Sun-Gi(順氣). Hang-Gi(行氣) - All existing living things as well as man maintain life on the ground of the pertinent harmony between the soul(精神) and the body(肉體). As soon as the harmony falls down, simultaneously life disappears as well. And Fung which means the outside process between Gi(氣) and Gi(氣) makes the action of their life cooperative and unified, Accordingy, the understanding of Fung, first, has to start wi th the whole thought that not only all Samul(事物) but also the soul and the body are one.
