Dendropanax morbifera is an endemic tree species of Korea, it is restricted to the southern parts of Korea. The internal transcribed spacer (ITS) region of nuclear ribosomal DNA (nrDNA) for Dendropanax morbifera grown at Bogil-do, Korea was determined. We investigated the sequence-based phylogenetic relationships of plants related and clarified its taxonomical position. The determined sequences consisted of 689 residues. ITS1 was 222 bp long while ITS2 was 233 bp long. The 5.8S rDNA was 160 bp long. The ITS region sequences of the Dendropanax species included in this study were obtained from GenBank. Oreopanax polycephalus was used as the outgroup. A pairwise alignment was calculated using the Clustal X program. A phylogenetic tree was constructed by the neighbor-joining method using the Tree view program. Sequence similarities among species including D. morbifera Bogil-do isolate showed the range 92.6 to 99.7% in sequence-based phylogenetic analysis using total 615 base pairs of ITS1, 5.8S rDNA and ITS2. D. morbifera Bogil-do isolate exhibited the highest degree of relatedness to D. chevalieri, sharing 99.7% ITS region similarity. D. morbifera Bogil-do isolate also showed to D. trifidus, sharing 99.4% ITS region similarity.

An epidemiological study was performed to know the recent infection status of Paragonimus westermani metacercariae (PwMc) in freshwater crayfish, Cambaroides similis, from 2 streams in Jeollanam-do, Republic of Korea. Crayfish were collected from creeks in Bogil-do (Island), Wando-gun, and in a creek near Daeheung Temple in Haenam-gun. The infection rate of crayfish with PwMc in Bogil-do was 89.8%, and the metacercarial burden was 37 PwMc per the infected crayfish. Crayfish in a creek near Daeheung Temple were larger and twice heavier than those in Bogil-do. Of them, 96.5% were infected with PwMc. An average of 140 metacercariae was found in the infected crayfish, almost quadruple to those of Bogil-do. There was a strong correlation between the number of PwMc and body weight of the crayfish. These results suggest that P. westermani metacercariae are still prevalent in crayfish of the 2 regions in Jeollanam-do, Korea.

Most of the studies on Confucian Architecture dealt with the administrative system and typification. The study was about the outline buildings of the Architecture. However, specific view of personal architecture is limited. The aim of this study is to clarify the idea of Seonbi, Confucian Scholars in Choson Dynasty, in building the second house, Byul-Seo Architecture. The Byul-Seo was used to Jang-Su(藏修) for training oneself and teaching his students, and You-Sik(遊息) for strolling the surrounding of nature. The Byel-Seo in Bogil-do by Gosan Yoon, Sun-Do is influenced not only by the idea of Confucianism which is 'knowing through by approaching to object(格物致知)', but also by Feng-shui and Taoism. From the idea of Gosan Yoon, Sun-Do in Byul-Seo Architecture, ecology and spirit of the times must applied to our modern architecture.

Collections of Semisulcospira snails and crayfishes were made to detect out larval trematodes in Bogil Islet, Wando-Gun, Chonra-Nam-Do, Korea in August, 1985. In addition, intradermal test to figure out the prevalence rate of paragonimiasis in the islanders was also carried out. The results are summarized as follows: 1) Nineteen out of 186 examinees(10.2%) showed positive reactions by intradermal test with Paragonimus antigen. 2) Forty four snails out of 182 snails collected were infected with trematode cercariae. These larvae were Metagonimus sp., Cercaria yoshidae, Cercaria incerta and Cercarianipponensis. 3) Metacercarial incidence of Paragonimus westermani in crayfish was 65.4%. Mean number of metacercariae per crayfish was 6.5.

The "ship's routeing" system was adopted by IMO and has been operated on the major sea routes of all over the world for the prevention of marine casualty and the improvement of marine traffic flow. Thereupon, also in Korea, the "Hong-do" and "Bogil-do" sea routes on southern coast were designated to mandatory sea area by traffic separation scheme(TSS) in 2003, and the "Geomun-do" sea route on southern coast was designated in 2005. But there were few or no studies on the effect of designated traffic separation scheme in Korea. For this reason, in this paper, we evaluated the contribution of traffic separation scheme to the prevention of marine casualty and the improvement of marine traffic flow after designation of domestic traffic separation scheme using data of the marine casualties and ship's tracks from AIS information. The results of evaluation showed that on the contrary, the cases of marine casualties were increased on some sea routes and regular traffic flows were disturbed by some vessels after designation of traffic separation scheme. For the safer and better sea routes, alternative ideas such as reposition of ship's routing on "Hong-do" and "Bogil-do" sea areas were suggested.

In this study, 6-10 clinically healthy farmed abalone, Haliotis discus hannai were obtained from Jeollanam-Do Wando Soan-myeon, Bogil-myeon, and Nohwa-eup monthly for 1 year 7 months and were examined histopathologically. As a result, the adductor muscle had severe cellular swelling and myonecrosis. These lesions were stained with hematoxylin and eosin and Giemsa. The lesions were not caused by infection of bacteria or parasites. We investigated the relationship between lesion frequency and water temperature and discovered that increased water temperature was associated with increasing lesion frequency. As water temperature is related to growth rate, increased growth rate was closely related to increased lesion frequency. We considered that these lesions could be a useful factor in measuring shellfish health.

When we put a construction on the space organization form of Seyeon-jong garden through a consequence of drawing analysis, we were able to certify that a certain space construction principle was applied as following. First, the arrangement and organization of space construction element embodied systematic order y clearing the character of space, and heightening the degree of cognizance with the means of functionability, scale, height, decorationability, an inclination of artificiality and nature, systemetic approchability. Second, the space construction element of Seyeon-jong garden pursued a harmony of human work and nature for creating a various atmosphere and visual quality. Third, Seyeon-jong garden constructed the space by establishing the measurement of human scale that introduced a conception of near, middle, distant view on the visual angle. Forth, Yun go san introduced the natural shape of 'The song of five friends' as a construction element, and represented the symbolism that he had seeked for throught he arrangement method, christening, composing technique of the space construction element for expressing ideal space which is described in 'The four season song of fishermen' spatially at Seyeon-jong garden. As the results of this study, that Yun go san created his own ideal space that he longed for at Seyeon-jong garden with applying fixed design system, and he realized his will that he strived to form a complete whole in perfect harmony.

We investigated and analyzed three Korean island sites (Bijin-do, Ae-do, and Bogil-do) and one Japanese site (Tachibanayama) of sword-leaf litsea (Actinodaphne lancifolia) forests, known as the climax forest, to discuss the vegetation succession sere of warm-temperature evergreen broad-leaved forests. We then reviewed the literature in Korea, Japan, China, and Taiwan to consider the distribution characteristics of evergreen broad-leaved forests, vegetation succession sere, and climax tree species. Although Mt. Tachibana and Ae-do showed the most advanced vegetation structure, the soil and ordination (CCA) analysis indicated that it was not enough to consider that the sword-leaf litsea forest was at the climax stage in the warm-temperature region. The Actinodaphne lancifolia forest is sparsely distributed in Korea and Japan while the common types of vegetation in the warm temperate zone region in East Asia are Machilus spp., Castanopsis spp., and Cyclobalanopsis spp. The vegetation succession sere of the Korean warm-temperature region is thought to have a secondary succession such as Pinus thunbergii, P. densiflora, Q. serrata (early stage) through Machilus thunbergii, innamomum yabunikkei, Neolitsea sericea, Actinodaphne lancifolia (middle stage) to Castanopsis sieboldii, Q. acuta, Q. salicina (climax stage). However, Machilus thunbergii will be the climax species as an edaphic climax in places where there is a strong influence of the sea wind, or it is difficult to supply the seeds of Castanopsis spp. and Cyclobalanopsis spp.

The importance of computer education has increased as a knowledge-based society develops. The national project for developing the industry of educational information will be ended by the year of 2000 From year 2001 on, the korean government plans to include computer education in Elementary and Middle-School Curricula. Teachers' colleges in Korea need to develop standardized teaching materials. These teaching materials may be used to teach a computer education class, plan a computer education curriculum, and do research on computer education teaching methods as well as computer education teaching materials. This study attempted to examine some aspects for developing teaching materials which we may use to teach pre-service teacher trainees in a teachers' college. The results of this study will help pre-service teacher trainees not only improve their ability of information literacy, but also obtain some techniques and strategies for teaching computer education in school.
