Literally, the mean of Tae-gye is highest brook. And on the basis of the acupuncture theory, Tae-gye point is the Soo earth point and source point of the Kidney Channel as well. In addition, Tae-gye point is one of the Yang-Returning Nine points. We were trying to study bibliographically on the Tae-gye point because Tae-gye point can be used very broadly across the symptoms in the theoretical aspect described above. As a results, we found out that according to the classical books of acupuncture, Tae-gye point is entering point of the Meridian Water as a source point and can be used at both Kidney-Sufficient Syndrom and Kidney-Deficient Syndrom. And Tae-gye can be applied to the disease of kidney or bladder that is urogenital symtoms, Also, Tae-gye is an useful option of tooth-ache, asthma, indigestion, constipation, edema etc whose cause is related with decrease of Kidney ki.

This study is to evaluate the characteristics of submerged biofilter process as pretreatment of raw water and alternative advanced water treatment system(AAWTS) composed with bioflitration, post-ozonation and GAC for Nakdong River by comparison of existing advanced water treatment system(EAWS), composed with pre-ozonation, flocculation, sedimentation, sand filtration, post-ozonation and GAC. In the biofiltration process, the removal of turbidity, color, KMnO₄consumption, NH₃-N and UV254 reached 98%, 95%, 70%, 72%, 79% respectively. The stable removal efficiency was obtained by the direct biofiltration after coagulant injection thought the influent was a muddy and highly polluted. The removal efficiency of the alternative advanced water treatment(AAWTS) using biofiltration process for turbidity, color, KMnO₄consumption, NH₃-N and UV254 was reached 98.5%, 98%, 82%, 90%, 92% respectively. It is equivalent to the removal efficiency of existing advanced water treatment system(EAWTS) though the demanded area and coagulant of the alternative advanced water treatment system using biofiltration process was decreased about 60% and 70% respectively.

본 연구는 골절단을 이용한 치아-치조골 분절의 급속 치아이동 후 치수, 치주인대 및 치조골의 변화를 유성견에서 평가하고자 하였다. 하악 제4소구치의 근심, 원심, 치근단 부위에서 피질골을 절단하여 치아-골 분절을 형성하고 하악 제3소구치를 발거하면서 협측, 설측 부위의 피질골을 삭제하였다. 1주 휴지기 부여에 따라 휴지기군과 비휴지기군으로 나누어 치아의존형 견인장치로 6일 동안 견인하고 강화기를 거친 후 0주, 1주, 2주, 4주, 6주, 8주에 희생시켜 치수, 치주인대 및 치조골의 조직 변화를 임상적, 방사선적, 조직학적 및 면역화학적으로 평가하여 다음과 같은 결과를 얻었다. 1. 치아이동 양과 강화기 동안의 조직 치유 양상에서 휴지기 유무에 따른 차이는 없었다. 2. 견인측에서 골형성은 강화기 8주까지 계속되었는데 강화기 1-2주에 가장 활발하였으며 6-8주간의 변화는 적었다. 3. 비휴지기군의 강화기 1주에서 치조골 흡수 및 파골세포 출현, 염증세포 침윤이 가장 많았으며, 특징적으로 파상아세포가 압박측의 치주인대와 치수 내에 나타났다. 4. TGF-β는 치조골의 골기질 및 골모세포, 파골세포, 치수 내 파상아세포에서 강양성 발현을 보인 반면 치수, 백악모세포, 무세포성 백악질에서 경미한 양성 발현을 나타내는 부위 특이성이 있었다. 5. TGF-β는 견인측 치주인대의 치조골에 인접한 혈관 및 치주인대세포, 골모세포에서 강화기 초기 1-2주에 주로 발현되었으며 6주 이후에는 발현이 크게 감소하였다. The movement of tooth-bone segments by osteotomy can simultaneously shift tooth and surrounding alveolar bone in a relatively short period. The purpose of this study was to evaluate the tissue changes in pulp, periodontal ligament, and alveolar bone in rapid tooth bone movement with osteotomy. The mandibular 3rd premolar of a dog was extracted and cortical bones of the buccal and lingual area were eliminated, and then cortical bones around the mesial and distal area of root, and below the root apex of the mandibular 4th premolar were osteotomized. After a one week latency period, a tooth-borne distraction device was activated for 6 days. And pulp, periodontal ligament and alveolar bone were evaluated clinically, radiologically, histologically and immunohistochemically at 0, 1, 2, 4, 6, 8 weeks of the consolidation period and conclusions were reached as follows. 1. Latency period didn't affect total amount of tooth movement and healing process of tissue during consolidation period. 2. Bone formation continued through 8 weeks of consolidation in distracted side, with a high peak at 1-2 weeks, and the lowest at 6-8 weeks of consolidation. 3. At 1 week of consolidation, alveolar bone resorption, osteoclast appearance and inflammatory cell infiltration were the most active, and dentinoclasts characteristically appeared on the pulp and pressure side of the periodontal ligament. 4. The expression of TGF-β was area-specific, as it was strong-positive at bone matrix, osteoblast, osteoclast of alveolar bone, and dentinoclast inside pulp, but weak in pulp, cementoblast and acellular cementum. 5. The expression of TGF-β was generally observed at the initial 1-2 weeks of consolidation at vessels, periodontal ligament cells, and osteoblast near alveolar bone on the distraction side of the periodontal ligament, and was significantly decreased after 6 weeks of consolidation.

제주지역에서 소비되는 식품 중 ^(137)Cs과 ^(40)K 방사능 농도

강태우,홍경애,박원표,유장걸 제주대학교 방사능이용연구소 2003 연구보고 Vol.17 No.-

본 연구는 제주지역에서 소비되는 식품류 중의 ^(137)Cs과 ^(40)K 방사능 농도를 조사하여, 식품 섭취에 따른 ^(137)Cs과 ^(40)K에 의한 내부피폭선량의 값을 평가함으로써 만일의 원자력사고로 인한 방사능 오염에 대처할 수 있는 기초 자료를 확보하고자 수행하였다. 시료로 채취한 식품류는 농산물 31, 축산물 6, 수산물 12, 임산물 4, 가공식품(차류) 3종류였고 방사능 분석은 고순도 게르마늄검출기가 장착된 감마선분광계로 수행하였다. 시료 중 ^(137)Cs 방사능 농도범위는 농산물이 MDA이하~650 mBq/㎏·fresh, 축산물은 16.6~542 Bq/㎏·fresh, 임산물 MDA이하~131 mBq/㎏·fresh, 수산물 39.1~294 Bq/㎏·fresh, 그리고 가공식품은 MDA이하~834 mBq/㎏·fresh이었다. ^(40)K의 경우는 농산물85.5~l16 Bq/㎏·fresh, 축산물 MDA이하~246 mBq/㎏·fresh, 임산물 50.1~657 mBq/㎏·fresh, 수산물 32.0~483 mBq/㎏·fresh 그리고 가공식품 33.6~l,065 Bq/㎏·fresh 범위였다. 시료 중 ^(137)Cs 방사능 농도가 가장 높은 것은 표고버섯으로 834 mBq/㎏·fresh이었으며, ^(40)K은 커피가 1.065 mBq/㎏·fresh로 가장 높았다. 각 식품류 중 ^(137)Cs와 ^(40)K에 의한 연간 유효선량은 농산물이 66.543 nSv로 가장 높았고, 축산물 19,311, 가공식품(차류) 6.648, 수산물 6,579, 임산물 850 순으로 낮았으며 이것을 모두 합한 총 연간 유효선량 값은 99,941 nSv이었다. 본 연구에 포함된 식품의 1인당 연간 섭취량이 연간 식품 총 섭취량의 60%임을 감안해도 자연환경 중에서 이루어지는 외부피폭에 의한 연간 유효선량 2,400,000 nSv에 비하면 무시할 정도로 평상시 식품섭취에 의한 방사선 내부피폭은 매우 미량이었다. 이상의 자료는 유사시 방사선에 의한 식품류 오염정도를 식별하는데 필수불가결할 것으로 사료된다. This work was conducted to provide the reference data of radioactivity in the foodstuffs at a radiological emergency situation in Jeju Island. The foodstuffs sampled were agricultural(31), livestock(6), marine(12) and forest products(4), and processed foods(3) consumed by Jeju Islanders. ^(137)Cs and ^(40)K activities were determined by HPGe γ-ray spectrometry. The activity ranges of ^(137)Cs were <MDA(less than minimum detectable activity)∼650 m㏃/㎏·fresh in the agricultural products, <MDA∼131 m㏃/㎏·fresh in the livestock, <MDA∼834 m㏃/㎏·fresh in the marine, <MDA∼246 m㏃/㎏·fresh in the forest and 32.0∼483 m㏃/㎏·fresh in the processed foods(tea). In case of ^(40)K, the activity ranges were 16.6∼542 ㏃/㎏·fresh in the agricultural products, 39.1∼294 ㏃/㎏·fresh in the livestock, 85.5∼116 ㏃/㎏·fresh in the marine, 50.1∼657 ㏃/㎏·fresh in the forest, and 33.6∼1,065 ㏃/㎏·fresh in the processed foods(tea). The highest activity of ^(137)Cs, 834 m㏃/㎏·fresh in was observed in oak mushroom and ^(40)K, 1,065 ㏃/㎏·fresh in coffee. Annual effective doses of ^(137)Cs and ^(40)K by intake of foodstuffs per capita were the following order ; agricultural products (66,543 n㏜) > livestock products (19,311 n㏜) > processed foods (6,648 n㏜) > marine products (6,579 n㏜) > forest products (860 n㏜). Therefor total annual effective dose was summed 99,941 n㏜ which is quite low level comparing to the annual effective dose byexternal exposure, 2,400,000 n㏜. The data obtained in this study can be useful for monitoring whether the foodstuffs are contaminated or not at an emergency radiation accident, and showed that the foodstuffs consumed in Jeju are safe in terms of annual effective dose of ^(137)Cs and ^(40)K.

賣出集中의 要因과 集中度에 관한 硏究

姜泰景 啓明大學校 産業經營硏究所 1988 經營經濟 Vol.21 No.1

This thesis suggested the direct elmeuts and indirect elements of market coucentration. The thesis look for which of the elements influence to higher concertration ratio. The direct elemeuts of market Concentration is entrybarriers, products discrimination, economies of scale, and mergers. ① I found out the higher producs discrimination create the higher market concenlration, and also coefficieut of correlation between the products discrimination and concentration ratio has appeared high level. ② Ecouomis of seale, as a minimum optimal scale(MOS), has deep correlated with the products concentration. ③ Necessary capital sacle and labour productivity as a elemeuts of entry barriers is related with the high concentration. ④ There is 3 Kinds of merger; product extension, market extension, and pure conglomerate mergers. A product-extension merger occurs when Firm X adds a product related to its existing product line by buying up Firm Y. A pure Conglomerate merger has none of these connections nor any other technical relation ships among the activites of the firms. Mergers create to a powerful origopoly and shared monopoly, and also create to as one of the elements of high market concentration. There(Table 14) was not over the 10% after the mergere. ⑤ The industry growth, firm growth, and thchnical development is the elements of indirect concentration. The growth industry make of low concentration ratio. So the oligopoly promote to industry growth and competition. ⑥ Technical development is make up high concentration in the short-time, but in the long-time it's an elements of low concentration. ⑦ The concenfration of the direct elements is more influced for the concentration rafio than the indirectrecf elemeufs of the concentration. ⑧ The ressearch suggested that coucentration does raise above costs. The market power's effects is to cut out put, raise price, and create excess profits.

강부경,이종섭,신태용,이은희,김형민 원광대학교 생명공학연구소 1996 생명공학연구소보 Vol.4 No.1

We determined for IgE in serum based on the enzyme-linked immunosorbent assay(ELISA) in vivo after intraperitoneal injection of Solanum lyratum extract for 14 days. The experiment showed as well whole spleen cells that Solanum lyratum extract enhanced IgE production in vivo. Solanum lyratum extract significantly facilitated the production of IgE by LPS-stimulated murine spleen cells. Solanum lyratum THUNB. also enhanced IgE production from mouse whole spleen cells. Lypopolysaccharide(LPS) stimulated IgE production was enhanced 1.4-fold to 2.7-fold by the addition of Solanum lyratum extract over a period of 7 days.
