We examined seasonal variation in fish species composition in coastal waters near Wolseong Nuclear Power Plant in the East Sea of Korea. A total of 72 species, 39 families, 14 orders, 46,214 individuals, and 4,639,667 g were collected. Glyptocephalus stelleri was the most dominant species by number of individuals (35%), followed by Clupea pallasii (26%). Liparis tanakai and Lophius litulon were the dominant species by biomass, accounting for 46% and 28%, respectively. We showed that bottom salinity and temperature are the most important environmental factors influencing fish species composition. Although bottom salinity did not differ statistically among seasons or stations, we detected some variation among stations. Additionally, bottom temperature differed among seasons and stations (P<0.05), affecting numbers of individuals and biomass. Thus, seasonal variation in fish assemblages can be classified into two groups: spring/summer and autumn/winter.

Generally, the radioactivity from NPP(Nuclear Power Plants) operation can be released below 3% of DRLs(Derived Release Limits) to environment. It was tried to understand which plant was efficient for absorbing radioactivity in this study. Pinus thunbergii Parl. and Viburnum awabuki K. KOCH were analyzed for radioisotope absorption. The samples were collected at three different locations depending on the distance from NPP at the vicinity 10km away, and 30km away. Gamma radionuclide was not detected from the samples, which means that the direct transition into the plant was not significant. Meanwhile, the very low level of radioactive tritium was detected in the samples. One remark was that every plant has different ability for tritium absorption. These results are expected to be applied to propagation and transplanting in radioactively contaminated area or reducing radioactivity in the soil and water near the plants.

본고에서는 경주 월성북고분군에서 조영된 적석목곽분의 존재 양태의 두 측면, 즉 묘형과 집단복합묘군에 대해 고찰하였다. 적석 목곽분은 호석으로 한정된 봉분 안에 단위묘곽이 설치된 원형의 단위고분이 기본형으로, 그 묘형은 단일원분, 연접분, 다곽분으로 구분된다. 단일원분은 피장자 1인의 단장분이고, 연접분은 일반적으로 부부나 혈연관계인 가족의 합장분이다. 다곽분도 대개 최하위 랭크의 묘곽들로 구성된 합장분으로, 월성북고분군의 왕릉구역에만 존재했던 것으로 보인다. 한편 현재 조사가 진행 중인 경주 월성북고분군의 쪽샘지구에서는 미고지를 따라 고분들의 소구역 군집현상이 보인다. 이는 당시 사람들이 친연관계에 따라 소집단별로 미고지를 점유하여 그 축선 방향으로 중형급 단일원분이나 연접분을 조영하고 그 주변으로 다수의 소형분들을 위성처럼 배치하여 집단복합묘군을 형성해 나갔기 때문이다. 대릉원지구를 비롯한 경주 월성북고분군의 왕릉구역에서도 고분들은 집단복합묘군을 형성하였다. 왕릉구역의 집단복합묘군은 마립간 왕릉인 초대형 단일원분이나 왕과 왕비의 합장릉인 초대형 표형분을 주분(主墳)으로 그 주변에 대소형 고분들을 배치하여 형성되었다. 집단복합묘군의 피장자 중에는 신분이나 사회적 인격이 대등한 부부나 혈연관계의 가족이 포함되었겠지만, 고분들 사이의 랭크 차이가 현저하여 피장자 모두가 혈연관계였다고 볼 수는 없다. 집단복합묘군에 포함된 하위 랭크 고분의 피장자들은 주분 피장자 및 그 가족과 주종관계의 '소속인'들이었다고 판단된다. 경주 월성북고분군의 적석목곽분에서 보이는 이와 같은 묘형과 집단복합묘군은 신라 마립간시기 중앙의 사회집단과 그 성격을 말해준다. 앞으로 이에 대한 좀 더 정밀한 분석은 당시 신라사회의 여러 측면을 밝히는 데 많은 기여를 할 수 있을 것으로 기대된다.

Through analysing on construction cases of stupa built in A.D. 7,8th, I have researched about these : constructive methods of inner soil of stupa, spatial compositions, characteristics of structures, arrangements of inner soil and etc. And cases analysed are six ; Mireuksajiseoktap(stone pagoda of Mireuksa Temple site), Gameunsajisamcheumgseoktap(three storied stone pagoda of Gameunsa Temple site), Goseonsajisamcheungseoktap(three storied stone pagoda of Goseonsa Temple site), Wolseong nawolliocheungseoktap(five storied stone pagoda in Nawonri, Wolseong), Guksagokseoktap(three storied stone pagoda in Guksa valley), Giamgokseoktap(three storied stone pagoda in Giam valley). Additionally we researched about inner soil of Sacheonwangsaji tapji(basement of stone stupa site in Sacheonwang Temple site) to speculate on composition of Synthetically, the foundation could be divided as core space and outer space. ; the former as structural function and the latter as ornamental function. And the core area could be divided again as center column space and buffer space. The relationship between core spaces and its formation are as belows; First, according to the area of foundation and scale of stone pagoda, formations of core are differed. As the scale of stone pagoda goes bigger, and the area of foundation goes larger, the structure of stone pagoda comprised by center column type and layered-core which endure upper load independently. On the contrary, as the scale of stone pagoda goes smaller, and the area of foundation goes lesser, the structure of stone pagoda tend to use only center column to endure upper part. Second, spatial composition of core area is comprised as two spaces, one which endure upper load and buffer space which absorb side pressure and upper pressure. The buffer space tend to be used in case of those structures which could not endure side pressure or have lots of joint. In some cases, it was located below the cover stone of foundation and gained upper load. And in case that have not gained pressure from side stone, the buffer space are comprised by smalle stone or roof tile to get structural supplement.

The purpose of this study was to survey the citizens for their satisfaction with the outdoor landscape lighting in Gyeongju Historic Areas registered as UNESCO World Cultural Heritage in November 2000 and thereupon, provide for some basic data useful to the design of the outdoor landscape lighting for the cultural properties. As a result of examining the conditions of the outdoor landscape lighting in Wolseong Zone of Anapji, Banwolseong, Dongbu Sajeokji, Cheomseongdae and Gyerim, there were found 391 lighting fixtures of 12 types in Anapji, 138 lightings of 4 types in Banwolseong, 38 lightings of 6 types in Cheomseongdae, 28 lightings of 3 types in Dongbu Sajeokji and 54 lightings of 5 types in Gyerim. As a result of analyzing citizens' satisfaction with the outdoor landscape lighting, it was found that citizens were satisfied more or less with the nightscape image changed by the outdoor landscape lighting; their satisfaction scored 3.836 on average for Anapji on a 5-point Likert type scale, 3.516 for Banwolseong, 3.446 for Dongbu Sajeokji, 3.650 for Cheomseongdae and 3.479 for Gyerim. However, citizens' satisfaction with the originality of the nightscape was generally low: 3.055 for Anapji, 2.914 for Cheomseongdae, 2.877 for Banwolseong, 2.847 for Gyerim and 2.665 for Dongbu Sajeokji. On the other hand, since most of the lighting fixtures were installed as inserted lights or floodlights, the color tones of light source were relatively highly distinctive, but the peripheral spaces around the cultural properties were rather dark, which means that citizens were feeling inconvenient more or less for using the amenities such as bench or waste box. All in all, their satisfaction with the outdoor landscape at the sample zone at night scored 2.981, lower than the normal level.

Marine algal flora and community structure were seasonally examined at three sites in the vicinity of the Wolseong nuclear power plant in Korea from February to November 2006. A total of 126 seaweeds including 25 green, 31 brown, 70 red algae, and 1 marine plant were identified. The greatest number of species occurred at Jeonchonri (101 species) followed by intake (88 species) and discharge (29 species) during the study period. Of 126 seaweeds, 76 annuals and 13 warm tolerance species were recorded. Dominant species based on important value (IV > 10) were Ulva pertusa and Enteromorpha linza at intake, U. pertusa and Padina arborescens at discharge, and Sargassum horneri and Corallina pilulifera at Jeonchonri shore. Annual average biomass exhibited a wide range of variations, from 40.67g m-2 in dry weight at discharge to 133.69g m-2 at Jeonchonri. Among six functional groups, dominant group was coarsely-branched form at intake and Jeonchonri, but it was different at discharge site as filamentous form. Seaweed community structures of discharge site were distinguishable in decreasing species richness, biomass, species diversity index (H’), richness index (R), and evenness index (J’). Also, the ratios of green algae, warm tolerance species, annual algae, filamentous form and dominance index (DI) remarkably increased. Such phenomenons of discharge site are usually found under environmentally stressful conditions such as high disturbance. Thus, I can conclude that the heated effluents of nuclear power plant act as environmental stress influencing seaweed community structures and it can be detected with various community indices.

The species composition and biomass of marine algae at the discharge canals of three (Gori, Wolseong and Uljin) nuclear power plants on the east coast of Korea were investigated seasonally from February 1992 to October 2000. As a result, 103-107 species of marine algae were found at the discharge canals during the past nine years. In general, algal communities established at the discharge canals were less diverse than those at the intake canals and control sites. 43 species (6 blue-green, 9 green, 10 brown and 18 red algae) of marine algae occurred more than 1/6 frequency and thus can be categorized as warm tolerant species. Among these, two green (Urospora penicilliformis, Cladophora albida), four brown (Sphacelaria divaricata, S. rigidula, Sargassum coreanum, S. fulvellum) and four red algae (Stylonema alsidii, Bangia atropurpurea, Hypnea charoides, Chondria crassicaulis) are recorded as warm tolerant marine algae for the first time in Korea during this study. Enteromorpha compressa, Padina arborescens, Amphiroa zonata and Ahnfeltiopsis flabelliformis were common species found more than 50% frequency at the discharge canals of all three nuclear power plants investigated. Dominant species in biomass were Padina arborescens and Amphiroa zonata. Results showed that, as a whole, the red algae appeared as predominant algal group at the discharge canals of all three nuclear power plants on the east coast of Korea. However, the biomass proportion of dominant algae at the discharge canals of each nuclear power plant varied over the year during the past nine years.

A servey on bovine fascioliasis in 52,876 cattle of Euiseong, Andong, Yecheon, Wolseong areas in Gyeongbug Province was carried out by the intradermal test, and the clinical side action of the positive cattle administered with DS-6 intramuscularly was observed. In addition pathological examination of 2 cattle died with side action of DS-6 was also conducted. The results of the studies are summarized as follows; 1. The average infestation rate of bovine fascioliasis was 31.1% and regional infestation rates were 35.1% in Eiseong, 34.5% in Yecheon, 32.2% in Andong, 26.9% in Wolseong, respectively. 2. The side actions were occurred in 1.5%(115/7,667) cf cattle administered with DS-6 and the clinical observations were salivation, dyspnea, hyperamia of conjunctiva, lacrimation, perspiration, urticaria, tremor, diarrhea, staggering, convulsion, edema and abortion. 3. Within 1 hour after the injection, side actions were occurred in 61.7% of the 115 cattle while they were observed in 37.4% of the 115 catte from 1 hour to 2 hours post injection. 4. The duration of the side action was less than 2 hours in 29.5%, 2 to 10 hours in 47.0% and more than 10 hours in 23.5% of the 115 cattle. 5. Autopsy findings and histopathological observations indicate that the death of cattle is caused by anaphylactic shock.
