The purpose of this essay is to explore the methodological standpoint and the meaning of 'Discourse Analysis' in policy science. I discussed it in three dimensions including: 1) the ontological point of view, 2) the epistemological perspective, and 3) researcher's position in policy research. 1) From the ontological standpoint, I explained the policy as a text, context, discourse, and ideology, that is focused on being constructed by the formative power of language. 2) The ontological standpoint produced "the argumentative turn" in the policy analysis, and many policy analysts emphasize the argumentative process of policy making and evaluation. This argumentation process includes the interpretative and critical viewpoints as well as the normative and ethical characteristics of policies in the discourse analysis. We should reexamine reality critically because discourse is ultimately influenced by the prevailing cultural and social norms. Therefore, an interpretative and critical viewpoint is an epistemological perspective in the discourse analysis. This critical approach creates an awareness of the limitations on our thinking under the particular major discourse, and requires the self-reflection within and beyond the discourse. This process leads to the human emancipation. 3) In order to achieve this emancipation, the last approach suggests that we need to scrutinize "the subject" as a researcher, who is also influenced and subjectified by the major discourse and, thus must deconstruct his or herself. Last but not least, we should emphasize the researcher's role as a listener of the minor voice(discourse) and even the silence of the clients.

The aim of this study was to clarify the physiological and psychological effects of walking around and viewing a lake in a forest environment. The subjects included 11 male Japanese university students (age: $22.0{\pm}1.2$ years) who were randomly assigned to visit either a forest or an urban (control) setting. They were instructed to walk a predetermined 15-min course and to view the setting from a seated position for 15 min. Heart rate variability, heart rate, blood pressure, pulse rate, and salivary cortisol levels were measured to assess the subject's physiological responses to the environment. Four questionnaires (SD method, reports of "refreshed" feeling, POMS, and STAI) were administered to assess the subjects' psychological responses. It was found that walking around and viewing a lake in a forest environment can suppress sympathetic nerve activity, increase parasympathetic nerve activity, and decrease the heart rate, blood pressure, pulse rate, and cortisol levels. In addition, a forest environment can enhance the "comfortable," "soothing," "natural," and "refreshed" feelings, improve the mood state, and reduce anxiety. These results provide scientific evidence of the physiological and psychological effects of forest therapy.

Noninvasive radial artery pulse wave has been widely used not only for the pulse wave analysis(PWA) itself but also for assessment of arterial stiffness with estimated aortic pulse wave from peripheral pulse wave. However, it has been found that the deformation of pulse shape can be caused readily by changing measuring position, indentation pressure, and so on. So, in this study, we have developed a system which can measure radial pulse wave and skin displacement simultaneously while the indentation body goes down to occlude subject's radial artery. This system can be divided into a measuring apparatus part, an indentation control hardware part, a data acquisition part and a control and computation part. And, the measuring apparatus consists of an arm-rest, a step motor, an indentation body, a laser displacement sensor(LK-G30, Keyence Co.) and pulse wave sensor. Under load-free condition and radial artery loaded condition, the evaluation of developed system has been performed. From these results, we can conclude: 1) The developed system can control the indentation body quantitatively and the adopted laser displacement sensor shows linear output characteristic even with skin as a reflector. 2) This system can measure the pulse wave and the displacement of indentation body, that is, skin displacement simultaneously at each specific level of indentation body. 3) This system can provide the number of motor steps used to get down the indentation body, the measured skin displacement, the calculated indentation pressure, the calculated pulse pressure and the pulse waveform as well as the information generated by combining these with each others. 4) This system can reveal the relationship between the morphological changes of pulse wave and the estimated displacement of radial artery wall by indentation. Consequently, the developed system can furnish more abundant information on radial artery than previous diagnosis systems based on tonometric measurement. In further study, we expect to setup the standard measuring process and to concrete the algorithm for the estimation of radial artery's diameter and of displacement of radial artery's wall. Furthermore, with well designed clinical studies, we hope to turn out the usefulness of developed system in the field of cardiovascular system evaluation.

The genres of fantastic of Korean films created in the 90s are diverse. The fantastics of these works are not manifested only in 'Ghosts' movies. For example, If the film Mystery Of The Cube, which is based on the mystery of Lee Sang, has a story of structuralist fantasy, we can say that a movie like Tell Me Something has a psychologically conventional fantastic. This study examines the fantastic of contemporary Korean films through 'completion of allegory based on realism'. For this, we borrows the fantastic concept of Etienne Souriau. In some films, fantastics can be found directly in the developing nature. In this case, the human being who justifies their domination of nature by upgrading their position as the objectifying subject of nature becomes 'alienated' in return. The notion of this alienation in film narratives is often revealed through allegories, particularly in the manifestation of fantasy by Étienne Souriau in the early 'personal experience'. Kim kiduk's film is a representative example of allegorizing elements of society through individual experience. Focusing on Kim Giduk's Bad Guy, this essay analyzes the process in which fantastic films of Korea in the 90s build up aesthetic fantastic through imitation of society.

The maximum voluntary ventilation (MVV) is one of the most widely used pulmonary function test, but its measuring method was very difficult and unreliable. However, it is need to get more easy and simple measuring method of MVV. Therefore, this study was attempted to get more easy and simple measuring method of MVV by means of the forced expiratory volume $(FEV_{T})$. The young and healthy 1,000 Korean students(592 male and 408 female) were cheesed for this purpose and whose ages were from 8 to 20 years. A spirometer (9L, Collins Co.) was used for the MVV and FEV, and they were measured 3 times at standing position, and the highest value was used. In the measurements, the subjects for MVV were asked for the breath as fast and deeply as possible for 12 seconds, and for FEV were asked for the rapid and forceful exhalation after a maximal inhalation (forced expiratory curve). In the FEV measurements toward the end of the expiration, the subjects were exhaused to continue the effort until no further gas was expired. During these measurements, the investigator stood by the subject to give a constant encouragement. FEV were calculated in the volume exhaled during the one-half $(FEV_{0{\cdot}5,}\;ml)$, the first second $(FEV_{1{\cdot}0,}\;ml)$ and the percentage of the total vital capacity exhaled during the one-half second $(FEV_{0{\cdot}5,}\;%)$. The results are summarized as follows: 1) The values of MVV were increased linearly with ages until 20 in both sexes. The values of male at the age of 20 was $168.2{\pm}2.5L/min$, and female at the age of 17 was $112.3{\pm}3.0L/min$, respectively. 2) The values of FEV (ml) were increased linearly with ages until 20 in both sexes. The values of $FEV_{0{\cdot}5}$ were $2,797{\pm}65.7ml$ in the male of 20 years and were $2,088{\pm}54.6ml$ in the female of 17 years, and of $FEV_{1{\cdot}0$ were $4,119{\pm}68.2ml$ in the male of 20 years and were $2,897{\pm}65.9ml$ in the female of 17 years, respectively. 3) The correlation coefficients between MVV and $FEV_{0{\cdot}5}\;or\;FEV_{1{\cdot}0$ (ml) were 0.82 or 0.85 in the male, and 0.77 or 0.79 in the female, respectively. 4) The prediction formulae for MVV to be derived from above results were: For male: MVV (L/min) =7.19+$0.05{\times}FEV_{0\cdot5}(ml)$, MVV (L/min)=11.25+$0.04{\times}FEV_{1\cdot0}(ml)$ For female: MVV (L/min)=16.03+$0.05{\times}FEV_{0\cdot5}(ml)$, MVV (L/min)=9.47+$0.03{\times}FEV_{1\cdot0}(ml)$.

The purpose of this study was to grasp the characteristics of composition regarding the material-centered integrated unit of environmental and natural studies, a science subject in Finland, to investigate a need for applying the material-centered integrated unit to the science curriculum of Korea. For the purpose, the study made an analysis on contents, inquiry activities, and visual materials (the most important in the elementary science curriculum and textbook composition), and it brought following results: First, as a result of analyzing the area of contents, the bicycle material-centered integrated unit comprised a large proportion of 44 pages (25.3%) of the whole 174 pages from the environmental and natural studies textbook for the third grade. The contents included such various concepts as traffic rules, safety, environmental protection and pollution, recycling and separate collection, tubes and triangular structures, wedges and screws, leverage, wheels, axles, gears, elasticity (spring), friction, and so on. Second, as a result of analyzing contents related to the thinking ability of inquiry activities, "expecting or confirming expectations" and "application" are included in every lesson, and one lesson is composed in such a way that students can study on bicycles as a practical material for their daily life and they can improve various thinking abilities. Third, as a result of analyzing the circumstances of inquiry activities, daily circumstances made up eight lessons (80.0%) and technical and social circumstances made up two lessons (20.0%) by focusing on bicycles, a material related to students' daily life. Fourth, as a result of analyzing visual materials, the percentage of pictures and photos was high at 53.4% and 45.2% respectively. As a result of analyzing the role of visual materials, the percentage of the illustrative role and explanatory-complementary role was high at 52.1% and 47.9% respectively. Lastly, as a result of analyzing from the epistemological view to interpret the relation between visual materials and students and the position of visual materials, the visual textbook materials were provided toward a way that students can decrease their feeling of epistemological separation in the three fields of ideational metafunction, interpersonal metafunction, and textual metafunction.

The present study aims to design an optimized hull shape of a floating pendulum-type wave energy converter(WEC). The purpose of these structure is to improve the performance and stability of the WEC by reducing its motion under operating and survival wave conditions. In this study, motion reduction structures, like restoring and dampling plates were installed on a floating pendulum WEC that has been the subject of previous studies. Restoring plates were installed to increase the restoring force and shift the natural period to a shorter period. Damping plates were installed to shift the natural period to a longer period by increasing the added mass. The effects of the structures were then analyzed under different incident wave conditions. The design parameters for the motion reduction structures were size, shape, and installed position. The wave-induced motion characteristics and performance of the floating pendulum WEC were also investigated numerically. Based on the simulation results, we are able to optimize the motion reduction structure of the WEC, thus improving its efficiency and durability.
