  • The objectives of this study were to investigate the location, shape, environment, and vegetation of the Village Forest in Gyeonggi-do and to evaluate the ecological integration and changes of the Village Forests to figure out the measures for conservation and management. There were 23 Village Forests remain in Gyeonggi-do. Ten Village Forests were established based on Feng-shui background. Many of them were found in Yongin area and southeast of Icheon. The Village Forests were owned by local community at 9 village and privately owned at 8 villages. Most Village Forests were managed by local communities except for the two managed by private person. Fifty-two percent of the Village Forests were in strip shape, and most of them were established by Feng-shui background or for the prevention of disasters. The average size of the Village Forests was relatively small at 3,046m2. The most frequent tree species found at the Village Forest were Zelkova serrata and Pinus densiflora. Over half of the number of Village Forests showed vertical structure of overstory trees only or overstory-sub overstory combination, which seemed to be resulted from the loss of understory plants by the activities of local residents. The Village Forests that had over 30% of damaged trees were found at 7 villages. The damages were caused by the road construction close to the groves, soil compaction, and tree death by covering lower stem with soil. The vitality of the damaged trees seemed to be significantly low compared to that of the undamaged. There were factors that determined the changes in the Village Forests: community ritual, institutional protection, designation as a water resource protection district, road construction, land use change, windstorm hazards, and development of forest areas. In order to conserve and manage the Village Forests appropriately, it is necessary to limit excessive use of the grove areas and maintain proper tree growing conditions by improving the soil environment. The development of neighborhood areas need to be controlled and community activities should be encouraged to maintain or restore the original landscape of the groves. Protection measures and supporting policies need to be enforced to keep the Village Forests from disappearing in near future.

  • This study was undertaken to evaluate the effects of $\beta$-mercaptoethanol ($\beta$-ME) on lipid peroxidation and fertilization ability in vitro by xanthine (X) - xanthine oxidase (XO) system in boar spermatozoa frozen-thawed. The boar spermatozoa were treated with X and/or XO, and the spermatozoa viability were measured by the eosin-nigrosin stain method. In control group, level of vitality in boar spermatozoa were higher than in medium with X, XO and X+XO groups. No significant differences, however, were observed under the all conditions. The percentage of spermatozoa that reached acrosome reaction were significantly (P<0.05) higher in sperm treated without that than with $\beta$-ME under the all conditions. On the other hand, when spermatozoa were inseminated in medium with X and/or XO, the penetration rates in all conditions were higher in medium with that than without $\beta$-ME. However, significant differences were not observed between medium with and without $\beta$-ME. The lipid peroxidation of sperm was evaluated on the basis of malondialdehyde (MDA) production. The MDA were higher in sperm treated without that than with $\beta$-ME under the above all conditions. However, significant differences were not observed between medium with and without $\beta$-ME. Sperm-SH group were higher detected in medium with that than without $\beta$-ME under the all conditions. The activity of sperm binding to Bona pellucida was also evaluated through binding to salt-stored porcine oocytes. In control group, sperm binding to zona pellucida were significantly (P<0.05) higher than in medium with X+XO groups. The sperm binding in all conditions were higher in medium with that than without $\beta$-ME. However, significant differences were not observed between medium with and without $\beta$-ME. These results suggest that addition of $\beta$-ME in X-XO system may play a positive role in improving of fertilization ability in vitro.

  • In this study, 40 hypersensitive teeth of 19 patients were investigated. The procedures performed were as follows: Before desensitization, EPT at occlusal third of buccal surface was done for the evaluation of pulp vitality and the EPT value was recorded for the reference value. And mechanical and thermal test was executed for the test of hypersensitivity. If the tooth responded to the above tests, we did EPT at the exposed surface, using toothpaste as a electrolite medium and recorded the EPT value at patient's response. After the tests had been done, desensitization procedures with Gluma(R) Desensitizer were performed according to the manufacturer's instructions. After desensitization, the same tests except EPT at occlusal third were repeated. All the 40 teeth responded positive before desensitization and negative after desensitization procedures. The EPT value at occlusal third ranged from 31 to 65 (48.9${\pm}$7.2). Before desensitization 34 teeth responded at EPT value of 2 and the remaining 6 teeth was in the range of 17 to 25. After desensitization all 40 teeth responded from 12 to 27 (19.6${\pm}$3.5). The 6 teeth responded at greater number than 2 before desensitization was in the range of 18 to 23. Within the limitations of this study we can conclude that: When a tooth with dentinal hypersensitivity responds to mechanical and thermal stimulation, the tooth shows very low resistance to electricity at the exposed surface while when a tooth is desensitized and doesn't show respond to mechanical and thermal stimuli, the tooth shows increased level of resistance to electric stimulation at the exposed surface. EPT can be used for the diagnosis of dentinal hypersensitivity. Furthermore EPT will be useful to evaluate the outcome of desensitization procedures. However, EPT is not a valid tool for measuring dentinal hypersensitivity.

  • This study confirmed depletion efficiency of nitrite when incubate lactic acid bacteria was isolated from commercial Chinese cabbage pickles (Baechu kimchi), pickled ponytail radishes (Chongkak kimchi), radish cube kimchi (Kaktugi) and pickled Wakegi (Pa kimchi) at temperatures of $15^{\circ}C$ and $25^{\circ}C$. At $15^{\circ}C$, lactic acid bacteria isolated from commercial kimchi depleted nitrite actively except Leuconostoc mesenteroides subsp. mesenteroides and Leuconostoc paramesenteroides. In particular, Leuconostoc mesenteroides subsp. dextrinicum and Leuconostoc lactis depleted nitrite by very actively without period adaptation in nitrite. Lactobacillus sake, Lactobacillus plantarum, Lactobacillus casei subsp. pseudoplantarum, and Lactobacillus coryniformis subsp. torquens depleted nitrite very actively after 1 day. L. mesenteroides subsp. mesenteroides depleted nitrite relatively actively after 2 days pass. In contrast, L. paramesenteroides displayed very low nitrite depletion ratio compared to other species. At $25^{\circ}C$, all lactic acid bacteria isolated from commercial kimchi did not need adapting period in nitrite, and depleted nitrite very actively except L. paramesenteroides. Also, all lactic acid bacteria except L. mesenteroides subsp. mesenteroides and L. paramesenteroides nitrite of more than 90% after 1 day, and L. mesenteroides subsp. mesenteroides depleted nitrite of more than 90% after 2 days. However, because L. paramesenteroides was not active even at $25^{\circ}C$, nitrite depletion efficiency was very low compared to other species. On the other hand, the same species of Lactobacilli and Leuconostocs except L. mesenteroides subsp. mesenteroides and L. paramesenteroides of other kimchi origin at $15^{\circ}C$ as well as $25^{\circ}C$ by vitality depleted nitrite very actively without statistically significant difference (p<0.05).

  • The world is preparing another unseen war, that is, the cultural war of digital economy which will dominate the new millenium. As the “contents”, which are composed of various ingredients of media, gain vitality, the developed nations are in preparation of the war with the “cultural industry” weapons. The digital economic experts say that the left out nations will become economic colony in the new millenium age. The most important characteristics of cultural industry is the unity of creativity and culture which is all the more improved on the basis of the culture created upon knowledge. This leads to competition between nations or regions, and to survive one has to develop the industrial structure through cognition of its own cultural value. Furthermore, it is not a short-term development and investment of cultural products but a study on the method to graft the cultural value to the industry itself. The multi-media period does not accept an independent medium, and the contents products are becoming the leading industry since il is proved that they last semi-permanently in the digital world. The victory lies in the quality and quantity of the contents as the high ability and variety of the technology of media advance in accordance to the market principles. Since the culture, science and economy are becoming one complex structure, all nations of the world are trying the evolve a unique design of their on culture on the basis of the global universality. In consequence, we should excavate a uniqueness from our cultural heritage and develop into a korean design which will be recognized in the world market. The value of our cultural property should not only be used as academic and research purposes but should be re-evaluated with modem view, recognized as the core element that decides the quality of life and developed into exclusive designs. The korean designs represent the mould concept of our people which evolves from the mould or shape alphabet of Korea To meet the requirements of the changing world and in preparation of the cultural competitive age, it is never too early to make a data on the korean designs through their analysis and evaluation.

  • Dopamine(DA), norepinephrine(NE), and epinephrine(E) belong to a class of neurotransmitters known as catecholamine (CA) which are synthesized and secreted by mammalian brain and adrenal medulla. CA regulate several behavior patterns connected with breeding, and regulate GnRH-gonadotropin hormone axis' vitality between hypothalamus-pituitary gland linking with reproduction freeze. The present study examined effects of sex steroid hormone on the transcriptional activities of CA biosynthesis enzymes, tyrosine hydroxylase(TH), dopamine $\beta$ -hydroxylase(DBH), and phenylethaolamine-N-methyl transferase(PNMT). Mature female rats were ovariectomized(OVX) and implanted with 17 $\beta$-estradiol(E$_2$: 500 $\mu\textrm{g}$/ml) or sesame oil. Forty-eight hours after implantation all the animals were sacrificed. Total RNAs were extracted immediately and were applied to semi-quantitative reverse transcription-polymerase chain reaction(RT-PCR). The expression level of TH was appeared by hypothalamus > SNc> adrenal medulla orders in OVX+Oil group, and by SNc > hypothalamus) adrenal medulla orders in OVX+E$_2$ group. Treatment with E$_2$ significantly increased TH expression in SNc and adrenal medulla but in hypothalamus, the reduced TH expression was observed. The expression level of DBH was appeared by adrenal medulla > SNc > hypothalamus orders in OVX+Oil group and in OVX+E$_2$ group. Administration of E$_2$ significantly reduced DBH expression in SNc, and increased in adrenal medulla. Two cDNA products, large(PNMT1) and small(PMNTs) species of 110bp difference, were amplified in SNc and hypothalamus, but only PNMTs was observed in adenal medulla. The PNMTs expression level was in the order of adrenal medulla > hypothalamus > SNc in both OVX+Oil and OVX+E$_2$ group. The PNMTs expression in SNc and adrenal medulla was significantly increased byE$_2$. The present report demonstrated that estrogen effects on transcriptional activities for CA biosynthethic enzymes were tissue specific in adrenal medulla as well as different region of brain. These results suggest that it might be crucial relationship between the type of estrogen receptor and CA enzyme gene expression.

  • The artist's interest has been captivated by ecological phenomena in Nature. Her keen captivation has then been focused into plastic art depicting the image of primitive life. The wide sweep of her work encompasses the totality of nature which consists of the human's subconscious power and imagination which she then portrays by organic images. These organic images are in contrast to scientific, mathematical and logical inference and consciousness. This research examines the character of the organic images in modern art by her analysis of some representative works by others. The image is an essential concept in the art which appeared in very different ways and in different perspectives. The image in the artwork appears to be the realistic expression until the early part of the 20th Century. Well into the 20th Century, it began being expressed in various ways such as combined images by imagination which is combined or rejected in the story of artwork. It also began being expressed by transferred images by changed original conditions. It is the main purpose of this research is to study of various expressions of organic images in the artwork of the Post-Modernism era. The character and meaning of organic image painting helps people to approach the human instinct more easily to find out the natural essence. It is also an objective of the organic image to tenderise our human sensibilities, thus helping us to regain vitality and recover our poor humanity in the barren wilderness of modern society. 'Life communion with nature' is a meeting point and common ground for Oriental Philosophy and organic image painting. Through this research, organic image painting is characterised in the four following ways : 1st) Organic image painting seeks regularity and perfection of outer shapes, in contrast to disordered and deformed nature, resulting in organic and biotic formalistic mode of plastic art. 2nd) Organic image painting seeks the formative. 3rd) Organic image painting pursues the priceless dignity of life by researching the formatted arrangement and figure, which contains primitive power of life. 4th) Organic image painting makes crystal clear the power of human and nature, which is a historic and biological phenomenon. This, in turn, exposes the humanistic view of the world from modern society best characterised in lost self-understanding, isolation and materialism. The representative organic image painting artists are Elizabeth Murray, Kusama Yayoi, and Niki do Saint Phalle. Elizabeth Murray used shaped canvas and a round construction of relief works. Kusama Yayoi used Automatistic expressionism originating from the realms of unconsciousness and which is represented by the mass and shape of a water drop. Niki do Saint Phalle shows the transcendence of universal life and anti-life to respect the dignity of life and the eco-friendliness relationship of human and nature in the post-modernism in art history. This is accomplished by surrealistic, symbolic, fantastic and humoristic expression. These three artists' works express the spirit of the organic image in contemporary art. It contains the stream of nature and life to seek not only the state of materialism in the reality, but also the harmonized world of nature and human which has almost lost the important meaning in modern times. Finally, this organic image is the plastic language of the majestic life. It is the romantic idea that the intimacy of nature and the universe and Surrealism, which emphasizes the unconsciousness , is the source of truth and spirit. Also it is influenced by primitive art and abstract art. According to this research, the subject 'Research About Organic Images' is not only an important element in the plastic arts from primitive society to the present, but is also fundamental to an true understanding of Post-Modernism.

  • Objectives: This study was conducted to investigate the change of health status through the intervention of physical activity arid exercise program for the people living in the area where health promotion program has been executed. Methods: The data was obtained from self--administered questionnaire. The questionnaire consisted of general characteristics, physical activity transition and health status variables using the SF-36(36-Item Short-From Health Survey). Data were analyzed 134 subjects participating in the physical activity arid exercise intervention programs. Results: The 35.1% of adults above 20 years of age are regularly physical activity and exercise before intervention program. but the rate increased to 49.3% after that. Frequency and duration of physical activity were increased, and frequency of participating in physical activity was increased from 0.9 times a week to 2.1 times especially. Scores of health status measured by SF-36 was increased in category (if general health after intervention of program, but those were decreased in category of vitality and mental health. Physical function of four groups classified by change of behavioral pattern were increased after intervention of program, especially in groups starting to physical activity. Conclusions: Physical activity and exercise is associated with health status. This study suggest that effective strategy and policy supporting for the promotion of physical activity and exercise should be needed in all peoples.

  • This study is a reinterpretation of characteristics of public space in contemporary cities with a view to liminal space. The conditions of pubic space now cannot be captured through the existing discourses of publicness, and public space. The basic premise of the study is that the idea of liminal space or liminality is useful to grasp the fluid and hybrid attribute of public space in contemporary cities. Liminal space, originally from anthropological studies, is the intermingled stage between two realms and the sustained period of the ritual. The idea has been widely used for various cultural phenomenon and spatial experiences. A literature review on public space and liminal space was carried out. Cases pertaining to public space with a view to liminal space were examined and discussed in detail. Through the careful reading of several public spaces with an angle toward liminal space, the new perspective toward public space will be drawn out. First, we need to emphasize the fluid spectrum of public space rather than the serial stage such as the public, the semi-public, the semi-private, and the private. Second, the idea will contribute to understanding the flexible state depending upon time. What we can learn from case studies is the volatile characteristics in public space as a common phenomenon support its vitality. This interpretation will contribute to the perception of a new horizon of public space. The nature of public space is unpredictable and free. In reality, the spectrum of public space will expand and fluctuate. Ironically, public space can be vitalized through enhancing and activating the private space. The intimate and complicated interface between the two realms is a key issue. The boundary of public space might be redefined to embrace the flexible the fragile nature of changing public space. These research implications will guide the thoughtful design and management of pubic space.

  • Purpose : Today, people usually die in hospitals and institution-sterile and strange, and equipped with a complex range of technology capable of supporting and prolonging life, frequently only biological one, when a return to health and vitality is no longer possible. Consequently, 'dying with dignity' has become a slogan of opposition to useless and degrading prolongation of life when a patient's organ, though still minimally functional, can no longer support or permit the exercise of self-fulfilling personal control over life's events. Dying with dignity, however, means entirely different things to different people. This study is to investigate the college students' attitude on terminal care and passive euthanasia. Methods : During June 1997, 337 college students participated in this study by responding to the pre-made questionnaire. It deft with the attitude to passive euthanasia, hospice, the most suffering fear facing the death, the preferred place and person to be with if dying. Results : 63.2% of subjects agreed to passive euthanasia. Only 14.2.% of college students can explain the concept of hospice, exactly They got the information about hospice by TV(43%), book(33.5%), religious group(12%) in order. The preferred death place was home(76.6%) and hospital(11.9%) in order. The Most suffering fear facing the death were about unknown(41.5%), loosing colleague(13.6%), pain(11%), isolation(6.5%) in order. Conclusion : About two-thirds of college students agreed to passive euthanasia. But euthanasia is dangerous and unnecessary. We should vigorously promote programmes of education in hospice and palliative medicine and care.
