There are so many cases which need grafts of bone defect as the reconstruction of post-tumor resection surgery site or trauma site, surgical management of alveolar cleft and oronasal fistula, bone grafts associated with osseointegrated implants and maxillary sinus lifting procedure. Among the method of bone defect reconstruction, that which uses the fresh autogenous bone has disadvantages that it gives also another trauma on the donor site and volume is reduced after the operation and it has limit of quantity. Another method using the commercial allogenic bone and composite bone like the Hydroxyapatite and Tricalcium phosphate has disadvantages that it takes poor tissue responses and its material works only as the passive scaffold. To gain the functional and much alveolar bone, Research is being carried recently that developing and purifying the various growth factor, applying the results of research to clinical situation. The materials promoting the bone formation are Bone Morphogenetic Protein(BMP), Platelet-Derived Growth Factor(PDGF), Transforming Gruwth Factor-beta(TGF-β). It is reported that Platelet-Rich Plasma(PRP) has PDGF, TGF-β and the abilily of promoting the bone formation. In this study, I compared the defect that have been healed naturally without any bone grafts as the control site, the other defect have been augmented only with bovine bone grafts, with another defect have been augmented with bovine bone grafts and Platelet-Rich Plasma simultaneously. I wanted to see whether much better results of bone formation on using the PRP have been gained, through the method of histologic evaluation. The results was gained as follows on the light microscopic examination. 1. The defect have been augmented with bovine bone grafts and PRP simultaneously showed the higher bone density and much bone formation than that have been augmented only with bovine bone grafts, especially on the eighth week's histologic examination. 2. Comparing the histologic specimen of the defects by the time elapse, Bone grafts with PRP simultaneously had the fastest bone growth rate among the three defects above. 3. The defect that have been heated naturally without any bone grafts had much fibrous tissue and less new bone formation. It seems that using the bone graft and PRP simultaneously on the bone defect gains the better bone healing as the above results.

Background: Adenosine interacts with A1 receptors present on the extracellular surface of cardiac cells, activating K+channels in a fashion. It produces coronary vasodilatation and AV nodal block. The half-time is one to six second and has ultra-short action. In ischemic heart disease, fractional flow reserve(FFR) can be achieved safely with intravenous adenosine infusions at a rate of 150㎍/kg/min which cause maximal coronary hyperemia. Purpose: We investigated the patients who have had ischemic heart disease(n=8). After adenosine intravenous administration(150㎍/kg/min), the effect cause maximal hyperemia of coronary artery. During peak maximal hyperemia, we reported clinical findings, coronary hemodynamics and electrocardiogram findings. Methods: After diagnostic coronary angiography and left ventriculography, catheter was advanced into the ostium of coronary artery. We investigated coronary hemodynamics such as systolic coronary artery pressure, diastolic coronary artery pressure, mean coronary artery pressure and heart rate. To assess the use of adenosine for determination of fractional flow reserve, hemodynamics and electrocardiogram were measured at basal state and during peak maximal hyperemia. Results: Symptoms developed 1.5-2 minute after adenosine intravenous administration and each symptom disappeared 2-2.5 minute after adenosine administration. Two patients represented asymptomatic appearance and six patients complained of flushing, chest pain, palpitation and headache. In eight patients with ischemic heart disease, 1.5 minute after venous administration of 150㎍/kg/min of adenosine, coronary artery pressure decreased and heart rate increased significantly. Conduction abnormalities after administration of 150㎍/kg/min of adenosine were transient 2nd degree AV block 2 cases(25%). Conclusions: Adenosine is a potent ultra short-acting vasodilator. Although coronary artery pressure decreased and heart rate increased and mild cardiovascular symptoms occurred after continuous infusion of 150㎍/kg/min of adenosine, it is useful as an agent for determination of fractional flow reserve.

본 연구는 대구지역에 거주하는 중ㆍ고등학생 639명을 대상으로 청소년의 소비자의식이 의복구매행동에 미치는 영향을 분석하였다. 연구의 결과를 요약해 보면 다음과 같다. (1) 소비자의식 유형은 권리의식, 소비자정보의식, 브랜드지향의식, 책임의식의 4개 요인에 따라 실리지향, 상표지향, 소비자의식지향의 3가지 집단으로 분류되었다. 실리지향 집단은 소비자의 권리의식, 소비자정보, 책임의식은 보통 정도이나 브랜드지향의식은 다른 집단에 비하여 낮게 나타났으며, 상표지향 집단은 권리, 소비자정보, 책임의식은 낮으나, 가격과 상표에 대해서는 관심이 높게 나타났고, 소비자의식지향 집단은 소비자의 권리의식이 강하고, 소비자정보를 많이 탐색하며, 가격과 상표를 중요시하지 않고, 책임의식도 높게 나타났다. (2) 남학생에 비하여 여학생들이 소비자정보의식과 브랜드지향의식, 책임의식이 높으며, 한달 용돈이 7만원 이상인 집단은 7만원 미만인 집단보다 권리의식은 낮고, 브랜드지향의식은 높게 나타났다. 아버지가 농림ㆍ생산직에 종사하는 청소년들이 권리의식은 높게, 소비자정보의식은 낮게 나타났으며, 어머니가 전문ㆍ행정ㆍ사무직에 종사하는 청소년들은 소비자정보의식이 조금 높게 나타났다. 월평균 가구 소득이 500만원 이상인 가정의 자녀는 다른 집단에 비해 브랜드지향의식이 조금 높게 나타났다. (3) 의복을 구입하는 주된 동기는 필요에 의해 구매하는 것으로 나타났으며, 과반수 정도가 계획구매를 하고 있으며, 주로 의류전문쇼핑몰을 이용하고, 의복에 대한 정보는 ‘제품’, ‘가족ㆍ친구의 조언’, 에서 주로 얻고 있었다. 의복 선택 시 중요한 요인은 디자인, 가격, 어울림 순으로 나타났으며, 구매 후 불만으로 가격, 서비스, 바느질상태를 표시하였고, 실제로 불평행동을 하는 청소년은 42%로 친지나 친구에게 불만스러웠던 점에 대해 불평한 경우가 가장 많았다. (4) 의복구매행동변인의 요인분석에서 구매저오원은 ‘중립적 정보원’ ‘개인적 정보원’ ‘상업적 정보원’, 구매선택은 ‘조화’ ‘유행’ ‘관리성’, 불만원인은 ‘외관’ ‘품질’ ‘서비스’의 3개 요인으로 나타났다. (5) 소비자의식형 집단은 개인적, 상업적 정보를 많이 활용하였으나 상표지향형 집단은 정보원을 중요시하지 않았다. 의복 선택요인으로는 소비자의식 집단은 조화와 관리성을 중시하나 상표지향집단과 실리지향집단을 관리성에 관심이 낮았다. 의복구매장소로 실리지향집단은 앙품ㆍ보세점과 의류도매상가를, 상표지향 집단은 의류전문쇼핑몰이나 유명상표 대리점을, 소비자의식지향 집단은 의류전문 쇼핑몰이나 상설할인매장을 주로 이용하였으며, 소비자의식 집단은 사적, 또는 직접 구매 후 불평행동을 많이 취하고, 실리지향 집단은 거의 불평행동을 취하지 않는 것으로 나타났다. To investigate the consumer awareness and clothing purchase behavior of adolescents, questionnaire was administered to 639 middle and high school students in Daegu. The results were as follows: 1. The consumer awareness of adolescents was analyzed to 4 factors: consciousness of right, consumer information, brand-orientedness and responsibility. Respondents were clustered into three groups; utility-oriented group, brand-oriented group, and consumerism-oriented group. 2. Respondents bought their clothes at specialty stores primarily. They used 'products', 'family's or friends' advices', and 'purchase experiences' as information sources. The important criteria for selecting clothes were 'design', 'price', and 'suitability for oneself. Dissatisfactions after purchasing clothes were with 'price', 'service', 'sewing', and 'size'. The complaining behaviors which respondents did mainly were 'telling friends about dissatisfaction with their purchased clothes', 'asking for changed dissatisfying products or asking for refund' and 'asking for mending'. 3. Infomation sources were categorized into 3 factors: 'neutral information source', 'personal information source' and 'commercial information source'. Criteria for selecting clothes were factor-analyzed into 'harmony', 'fashion' and 'management of clothes'. 'The factors of dissatisfactions with purchased clothes were 'appearance', 'quality', and 'service'. 4. The differences by the consumer awareness in clothing purchase behaviors among consumer groups : In information sources, criteria for selecting clothes, complaining behaviors, purchasing places, three consumer groups were different significantly.

Purpose : The purpose of this study was to analyze the lower third facial changes in frontal view after mandibular setback surgery. Materials and Methods : In this study, fifteen subjects(6 males and 9 females) with class III dental and skeletal malocclusions who were treated with BSSRO(Bilateral Sagittal Split Ramus Ostetomy) were used. Frontal cephalometric radiographs were taken preoperatively and more than 6 months postoperatively, and hard tissue(H2-Hl) and soft tissue changes (S2-S1) were measured on vertical and horizontal reference lines. In 15 cases, changes which developed more than 6 months after surgery were studied. Results : The results were as follows. 1.In the facial height, hard tissue decreased(2.46±2.76mm) with statistical significance(P<0.01), and soft tissue also decreased(1.64±3.66mm). As a result, the facial height generally becomes shorter after sagittal split ramus osteotomy. 2.In the mandibular width, hard tissue decreased(2.08±3.59mm) with statistical sgnificance(P<0.05), but soft tissue increased (2.14±5.73mm) without statistically significant difference (P>0.05) postoperatively. 3.In the facial index, hard tissue decreased(0.23±2.21%), but soft tissue increased(2.41±3.46%) with statistical significance. Conclusion : One of the main purpose of orthognathic surgery is to achieve facial esthetics and harmony. In order to fullfill this purpose, it is important to carry out a precise presurgical treatment planning by estimating the changes of frontal profile after surgery.

심미적 비전과 더 나은 삶

정현종 연세대학교 인문과학연구소 1994 人文科學 Vol.72 No.-

Today if there are humanistic reflections upon our life, they are based upon our judgement that we coud not attain spiritual and emotional richness comparable to the material and scientific achivement. Even worse, compared with the material side, we cannot fail to observe that the spiritual condition of our life is getting more violent, wasteful, and fragmentary. Since what we are trying to define here­­a vision for a better life­­is possible only on the bases of spiritual richness and emotional flowering, and since the only way to do that is to open an aesthetic vision of life, I have depicted an aesthetic view of the world derived mainly from the poems of Neruda, Lorca, and American Indian poets.

林鐘弼,南官凍,金勳,김현주 又石大學校 1992 論文集 Vol.14 No.-

A peony is the perennial plant which comes under Paeoniaceae and classifies a white peony(Paeonia japonica MIYABE et TAKEDA) and a red one(Paeonia albiflora PALLAS). The former lays in a supply of the blood and alleviates an nerve, while the latter lays in a supply of vitality and purifies the dirt blood. They have different uses but there is little difference between them in appearance. Thus at present the white peony is used together with the red one clinically. The purpose of this thesis is to examine and compare the structural and anatomical difference in root and stem of red and white peony. This comparison has led to following conclusions: 1. The length of the vessel members of the red peony is a bit longer than that of the white one in the stem and the root. 2. The width of the vessel members is wider than that of the white one in the stem and the root. 3. There is a clear difference between the two species in which the secondary xylem in root of the red peony is discontinuous scalariform arrangement while that of the white one is continuous radial arrangement.
