Design takes concrete form from the things which are not yet exist to the molded reality. Creation of value which is accompanied by the rational value could be possible only through the searching examination of the basic concept. All designs are under circumstances because the results and the character of the problems are different under the given conditions and circumstances which are the characteristic of the design. The aim of this study is searching for the differential design conce- pt which is the most appropriate and reasonable in the basic design process in which the phase of the analysis, synthesis and evaluation of the problem. First of all the pursuit value of the times and the change of the view point of value of the product design. How the pursuit value of times were searched and analyzed. Analyze the successful product design realization of the typical trend of the modern design which are 3-2. function-focused design, 3-3. emotion-centered design, 3-4. image communicative design through the metaphor, 3-5. environmental affinity design. On the base of the case analysis how to apply the differential design concept which is coming as a trend in the future society which are sustainable developing society was examined closely. The outcome through the analysis of the success cases are as follows, \circled1 the value of the spirit of the times should be emphasized as the design image, \circled2 environmental appropriateness should be taken into consideration as the first primary factor, \circled3 the realization of value of the fulfillment of differential consumer's needs, \circled4 lead to prolong the life cycle of the product, \circled5 promote the sustaining growth of enterprise, \circled6 user-centered product value should be the first consideration. \circled7 It is necessary to overcome the cultural andinguistic barriers and to reflect the metaphor which people remember well. \circled8 The application of human's true character should be decided beforehand. It is the commonness of values of times and customs. \circled9 The differentiated design concept which meets our mental satisfaction, not material one, will be required. In addition to this the creative and differentiated design concepts which are accompanied by the good design factor under the base of product could achieve the emotional consensus from the consumers. That is, the value of all designs should be estimated by the base of the humanism ' The human beings are the barometer of all things".ngs".uot;.

The East has recognized 'similar forms' and 'similar spirits' as important topics in expressing an object. Figure painting, in particular, has attached importance to 'transmission of spirit'. Gu Kaizhi (345-406) definitely presented the transmission concept and made it the moot important criterion in painting criticism. By identifying the possibility of revealing spirit through a form, he recognized the 'expression of will' in a creator's work and the experience of such 'expressed will' by an appreciator to be the essential acts of art. Thus, he said, a figure painting revealed the character and nature of the depicted object rather than reproducing its form. Regarding art as a person creating the saintly way of life via developing own character, he attached importance to the will of an artist as the central aesthetic subject. This dissertation explores the keynote of the spirit expressing an artist's inner world and the external shape of a figure. It is carried out by investigating the process of Gu Kaizhi's theory (namely spirit transmission and revelation in painting) leading to Su Dongpo's assertion that "the nature of things" and later leading to Yun Duseo's "theory of the way of painting" as the spirit-transmission theory faithful to the principle of revealing spirit through a form in Chosun. The chronological study of the aforementioned works reveals that the relation between an artist and an object is important at the stage of setting aim in producing a work, and this dissertation analyzed it with four elements: (1) creating work based on the viewpoint of nature that heaven and man are one; (2) reflection of the creator's character (including his/her nature, temperament, spirituality, and emotion during the creation) and the artistic merit of a picture; (3) the dialectic unification between the true and the false through space which is a volitional state as creative thinking space; (4) importance of artist's will above the technique used such that a purposeless, inactive and plain work (where human will is combined with heavenly one) was pursued because the picture is regarded coming from the mind created in the unity of host/artist and guest/object. Thus, through his/her intuitive insight is the world where self is united with the cosmos symbolized. Such expression of an artist's inner world and the external shape of a thing pursues the stage of materialization and creates the new modes such as using space, a variety of brushstrokes, and accidentality and improvisation of India ink. In particular, the writer sees that such expression which enables a creator to express his/her nature or personality (and even the emotion) at the time of creation will be highly worth studying in the future, in accord with the pursuit of contemporary painting being expressed as an abstract aspect.

Purpose : To determine incidence, characteristics and risk factors associated with intrauterine intraventricular hemorrhage(IU-IVH) among premature infants. Methods : The medical records of infants with intraventricular hemorrhage(IVH) admitted to the neonatal intensive care unit of Asan Medical Center from January 1999 to June 2003 were reviewed retrospectively. Infants whose IVH with cystic change were detected within five days of life were defined as the IU-IVH group. The control group included those without any IVH. Various maternal and neonatal factors were evaluated between the IU-IVH and control groups, and risk factors for IU-IVH were identified using multiple logistic regression analysis. Results : The incidence of IU-IVH was 49/1024(15.9%). Mothers who are younger, primiparous, use less antenatal steroid, and neonates with greater incidence of neonatal respiratory distress syndrome, had higher incidences of IU-IVH compared to neonates with normal neurosonography. Risk factors associated with IU-IVH included neonatal respiratory distress syndrome and placenta infarct by placenta biopsy. Most infants with IU-IVH were ${\geq}1,501g$, ${\geq}34$ weeks gestational age and had low grade IVH. The size of the cysts associated with IU-IVH remained the same or disappeared in 96 %. IU-IVH does not seem to affect short-term neurodevelopmental outcome although a longer period of follow-up is needed. Conculusion : IU-IVH occurred mostly in ${\geq}1,501g$, ${\geq}34$ weeks infants with grade I IVH without developmental delays. However, the high incidence of total IVH merits more attention in terms of awareness of its existence as an unusual IVH among premature infants.

This study was conducted to set the proper sterilization standards of casing soil for the stable production of button mushroom(Agaricus bisporus) from mushroom disease that occurs in infection of casing soil material. Changes of aerobic bacteria are increased as the longer grow-out period and sharply increased after second flushes. Fluorescence Psuedomonas showed high density at high sterilization temperature and $100^{\circ}C$ treatment has extremely high density at 30 min and 60 min in casing 22 days. Density of thermophilic actinomyces is sharply increase from casing with soil and the highest density at 22 days of casing and rapidly decrease after first flushes. Sterilizing temperature of casing soil affects quality and quantity of button mushroom. Treatment of 60 min, 90 min at $80^{\circ}C$ and 30 min at $100^{\circ}C$ produced the highest mushroom yields, especially mushrooms yields of A grads were the highest at treatment of 90 min at $80^{\circ}C$. Treatment of 60min at $100^{\circ}C$ products many yields, however, this treatment has low economic feasibility for its yields. Sterilizing temperature of casing soil has an effect on generating diseases and insect pests. Treatment of 60 min, 90 min at $80^{\circ}C$ and 30 min $100^{\circ}C$ showed lower incidence than the other treatment. Although treatment of 30 min at $100^{\circ}C$ causes low diseases and mushroom fly damage, it has low mushroom yields. Furthermore, although treatment of 60 min at $100^{\circ}C$ has high mushroom yields, it causes high diseases and mushroom fly damage. Therefore the best conditions for the sterilization of casing soils was 60 min and 90 min at $80^{\circ}C$.

For the purpose of preciously describing real time traffic pattern in urban road network, dynamic network loading(DNL) models able to simulate traffic behavior are required. A number of different methods are available, including macroscopic, microscopic dynamic network models, as well as analytical model. Equivalency minimization problem and Variation inequality problem are the analytical models, which include explicit mathematical travel cost function for describing traffic behaviors on the network. While microscopic simulation models move vehicles according to behavioral car-following and cell-transmission. However, DNL models embedding such travel time function have some limitations ; analytical model has lacking of describing traffic characteristics such as relations between flow and speed, between speed and density Microscopic simulation models are the most detailed and realistic, but they are difficult to calibrate and may not be the most practical tools for large-scale networks. To cope with such problems, this paper develops a new DNL model appropriate for dynamic traffic assignment(DTA), The model is combined with vertical queue model representing vehicles as vertical queues at the end of links. In order to compare and to assess the model, we use a contrived example network. From the numerical results, we found that the DNL model presented in the paper were able to describe traffic characteristics with reasonable amount of computing time. The model also showed good relationship between travel time and traffic flow and expressed the feature of backward turn at near capacity.

The purpose of this study is to analyze the effects of climate change on the nonpoint source pollution in a small watershed using a mid-range model. The study area is a basin in a rural area that covers 384 ha with a composition of 50% forest and 19% paddy. The hydrologic and water quality data were monitored from 1996 to 2004, and the feasibility of the GWLF (Generalized Watershed Loading function) model was examined in the agricultural small watershed using the data obtained from the study area. As one of the studies on climate change, KEI (Korea Environment Institute) has presented the monthly variation ratio of rainfall in Korea based on the climate change scenario for rainfall and temperature. These values and observed daily rainfall data of forty-one years from 1964 to 2004 in Suwon were used to generate daily weather data using the stochastic weather generator model (WGEN). Stream runoff was calibrated by the data of $1996{\sim}1999$ and was verified in $2002{\sim}2004$. The results were determination coeff, ($R^2$) of $0.70{\sim}0.91$ and root mean square error (RMSE) of $2.11{\sim}5.71$. Water quality simulation for SS, TN and TP showed $R^2$ values of 0.58, 0.47 and 0.62, respectively, The results for the impact of climate change on nonpoint source pollution show that if the factors of watershed are maintained as in the present circumstances, pollutant TN loads and TP would be expected to increase remarkably for the rainy season in the next fifty years.

Purpose : To investigate the feature of the range of measles in 2000, we studied epidemics of the measles in western Kyungnam District. Methods : Among 489 patients under 15 years of age who visited or were admitted to in our hospital from January to December in 2000, we selected 344 patients whose measles IgM antibody was positive. We investigated age, monthly incidence, clinical features, vaccination history, and measles IgG antibody. Results : Patients under 12 months of age occupied the largest proportion(36.9%). Patients firstly occurred in May and geometrically increased from October. Fever, cough and rashes were observed in all patients but conjunctivitis in 54.9%, Koplik spot in 23.8%. The first vaccination ratio was 41.8%. Compared with the number of patients and the first vaccination ratio, the first vaccination ratio was the lowest under 12 months of age. After that age group, the number of patients was decreased as the first vaccination ratio was increased. Among 152 patients sampled for measles IgG antibody, 35 patients had received the first vaccination and 6 patients had received the second vaccination. Among 35 patients who received the first vaccination, 22(62.9%) patients were negative of measles IgG antibody. Among 6 patients who received the second vaccination, 3(50%) patients were negative. Conclusions : Measles patients under 12 months still dominated. Therefore, routine vaccination of single measles vaccine, is currently done at 6 month when measles are prevalent, should be considered. High first vaccination failure suggests problems of vaccines itself, transport and storage rather than vaccination methods. Therefore a thorough investigation should be made.

The culture of Gugok (九曲) and Dongcheon (洞天), which tries to reach the ideological culmination in Confucianism, was widespread throughout the Joseon dynasty. This was an extension of the spirit of studying and honoring Zhu Xi (學朱子, 尊朱子); thereby, Confucian scholars in Joseon expressed the will to follow the teachings of Zhu Xi (朱子) and comforted themselves that they were in the course of attaining the truth. As a realization of this expression of will, scholars designated and operated various scenic sites as Gugoks, following the example of Zhu Xi's Mui Gugok (武夷九曲), and Dongcheons, as a representation of the utopia. These designations are widespread nationwide, with around sixty Gugok locations that have now been reported in academia. However, the actual number of Gugoks exceeds this number, and many of them are currently not identified concerning the exact locations. Therefore, the purpose of this study is to identify the locations of Gugoks and Dongcheons scattered around Seoul, Gyeonggi and Gangwon regions. For the coordinates of Gugoks and Dongcheons, this study referred to the literature, web search and the books published by local cultural institutes. Based on the collected information, the researchers conducted field trips to investigate whether the record exists as a real location and, if so, acquired their coordinates. This study also provides the tables of Gugok or Dongcheon that only exists in the imagination, existed before but now are lost, or are inaccessible. Eight locations in Seoul, Gyeonggi, and Gangwon regions are understood as Gugok. Among them, Gogun Gugok and Okgye Gugok have relatively clear locations and records. Byeokgye Gugok and Suhoe Gugok, on the other hand, has many locations and titles overlapped, and their established time and managers are unclear. As for Ui Gugok in Seoul, it is known to be set by Hong Yangho, but some parts of its locations are confirmed, others are in dispute, and many locations are damaged. Thirty-eight locations in Seoul, Gyeonggi, and Gangwon regions are understood as Dongcheon. There are sixteen Dongcheons in Seoul area. Among them, those including Dohwa Dongcheon, Yangsan Dongcheon, and Ssangnyu Dongcheon actually exist but are forbidden to be accessed. There are thirteen Dongcheons in Gyeonggi area. The exact location of Onsu Dongcheon cannot be confirmed because of the development; Gwirae Dongcheon has historical records, but the actual existence cannot be confirmed. There are nine Dongcheons in Gangwon area. The researcher judged that Hwaeum Dongcheon is the misspelled record of Hwaeumdong Jeongsaji (華陰洞精舍址), which is located at the upstream of Gogun Gugok.

The Purpose of this study is to suggest strategies for environmental education through the Practical Arts(TechnologyㆍHome economics) Subject in a viewpoint of the clothing & textiles resources to resolve problems in the clothing life area. For this, this study was carried out through review of literature which is related with the consumption, the environmental problems, the environmental policies, and regulations of the government and new environmental technologies, of clothing & textiles industries and environmental education. The major findings of the study were as follows; 1) The environmental education system model in a viewpoint of the Clothing & Textiles resources was developed. This model system is consisted with interactions on school, government, industry, home and non-government organizations. Thus, the fact that Practical Arts(TechnologyㆍHome economics) Subject were the most effective subject to teaching the environmental education viewpoint of the Clothing & Textiles resources was confirmed. 2) The standards were analysed out to analyse the contents in the clothing area of the Practical Arts(TechnologyㆍHome economics) Subject. It were consist of 4 factors and 12 elements under the factors: Awareness of clothing & textile resources(clothing consumption, production of clothing & textile and environmental problems). Planning and buying of clothing(planning, buying), Management of clothing(understand of textile. human body & environment, laundering and Environmental pollution, arrangement & conservation) Recycling & exhaust of clothing(contribution, redesign, recycling, exhaust) 3) Analysing the current Practical Arts (TechnologyㆍHome economics) subject from the Environmental education in the clothing section, the environmental education related with clothing were taught the most in the middle school course, and environmental contents were concentrated in the recycling factors. but not so much on other factors. 4) After analysing the Practical Arts (TechnologyㆍHome economics) subject, the strategies were suggested for reinforcing the environmental education in the clothing of the Practical Arts(TechnologyㆍHome economics) subject.

Background: Current vascular prostheses are considered still inadequate for reconstruction of small-diameter vessels. To evaluate the potential use of xenograft vessels as small diameter arterial grafts, we implanted porcine vessels in goats. The grafts were treated with two different processes, freezing and acellularization, before implantation, and gross inspection as well as microscopic examination followed after a predetermined period. Material and Method: Bilateral porcine carotid arteries were harvested and immediately stored at $-70^{\circ}C$ within tissue preservation solution. One of them was designated as frozen xenograft vessel. The other one was put on acellularization process using NaCl-SDS solution and stored frozen until further use. Grafts were implanted in the place of carotid arteries of the same goat. The grafts have remained implanted for 1, 3, and 6 months in three animals, respectively. Periodic ultrasonographic examinations were performed during the observation period. After explantation, the grafts were analyzed grossly and histologically under light microscope. Result: All animals survived the experimental procedure without problems. Ultrasonographic examinations showed excellent patency of all the grafts during the observation period. Gross examination revealed nonthrombotic, patent lumens with smooth surfaces. Microscopic examinations of the explanted grafts showed cellular reconstruction at the 6-month stage in both grafts. Although more inflammatory responses were observed in the early phase of frozen xenografts, there was no evidence of significant rejection. Conclusion: These findings suggest that porcine xenograft vessels, regardless of pre-implantation processes of acelluarization or freezing, can be acceptably implanted in goats, although short duration of observation in a small number of animals may limit this study.
