이 연구는 부동산개발사업의 성공에 중점 둔 금융 수요자(GP)와 사업참여에 신중하고 보수성향을 가진 금융 제공자(LP)간의 이익 배분의 합리성을 탐색하는 것이다. 다시 말해서, 부동산 개발사업의 지분 투자자간, 위험의 분배와 그에 비례한 합리적이고 바람직한 개발이익의 배분 구조를 규명하는 것이다. 이 연구는 2가지 관점에서 개발이익의 배분 구조를 분석한다. 첫째, 투자비율에 비례한 이익 배분 구조를 분석하고. 둘째, 허들을 추가한 상태하에서 발생하는 이익배분 구조를 탐색한다. 투자자 간의 투자비율에 비례한 이익 배분은 위험 기피적인 유한책임 투자자의 입장에서는 받아들이기 어려운 구조다. 또한 허들이 많아질수록 무한책임 투자자의 업무성과 향상은 추가수익의 발생으로 유인기능을 한다. 따라서, 부동산개발사업은 상당한 리스크를 수반하므로 워터폴 구조에 의한 무한책임 투자자와 유한책임 투자자의 개발이익 배분의 합리적 결정 모델을 제시한다. This study focuses on the possibility of structuring the business between the GP, which expects the success of the development project, and the LP, who is careful to participate in the project and has a conservative tendency. In other words, it iinvestigates a profit sharing structure between equity investors in a real estate development project and the distribution of risks and the corresponding reasonable and desirable development gains. This research will analyze Choi Hyuk-jae and Jang Hee-soon s existing research in 2020 from two perspectives. First, explore the profit-sharing structure proportional to the investment ratio. Second, we add four hurdles to identify a various profit-sharing structure. Distribution proportional to the investment ratio between each investor is difficult to accept for risk-averse limited liability employees. In addition, the more hurdles are introduced, the more additional promote is generated considering the performance of the general partner, which functions as an incentive design function. Therefore, in a real estate development project where significant risks are inherent, the distribution of development profit between the general partner and the limited partner under the Waterfall structure is inevitable.

Mobile nodes in ad hoc mobile networks typically communicate over wireless channels and are capable of movement. These are networks that support multihop communication and can be formed on a temporary basis. This paper proposes a solution that allows mobile nodes to access the wired Internet and to roam from base station to base station. And we also develop the efficient method that adapts in Global MANET which can be changed over time. It is observed that we can reduce not only error detection time but also network load, thus increasing the data reception rate in Global MANET Environment.

A 29 year old female patient came with grade NYHA Fc IV dyspnea of 1 month. No abnormality was heard during auscultation. Arterial blood gas analysis done due to shortness of breath showed a decreased PO_(2) of 64.6 mmHg. Computerized tomography(CT) was checked due to multiple nodules seen in both lower lung fields of the chest X-ray. CT revealed multiple pulmonary arteriovenous malformations in both the mid and lower lung fields. Dyspnea was uncorrected by the application of oxygen. Coil embolization showed improvement of PO2 and dyspnea. The CT follow up at 9 months after the procedure showed no progression of the arteriovenous malformation without any additional symptoms nor dyspnea.

B2C(Business to Customer) is one of the electronic commercial transaction. Recently, Internet Shopping mall that is the typical type of it has been on the sharp rise But of all the internet users, those who purchases actually online is few. With typical business, both parties(buyer and seller) came face to face so that they can check the quality of product and pay it to get directly. For e-commerce, however, these things are done in the virtual area of Internet. Therefore it is not possible for customers trust anything about online shopping as others easily, and it causes buying online not to be facilitated inevitably. For example, trying to buy online, customers worry about if the quality of products displayed in the internet mall is acceptable, delivery is to be done correctly and someone can steal our credit card number provided for paying Ironically while buying online increases steadily, reliability for shopping mall is no improved much better. As a result, to facilitate business to customer(B2C), it is required to analyze the factors to make online shopping reliable and the factors that are chief in improving reliability. This document reviews the major factors in trust, and relationship between customers trust and purchasing power, based on the recognition that reliability in business to customer(B2C) is important. With doing research in existing studies and classifying them, theoretic model is provided. For verification and discussion about this model, surveys targets 20∼30 years ole men and women have been made. First, the reputation of Internet Shopping mall do not influence customer trust. Second, two factors of safetyness and trust in e-channel do not influence customer trust, significantly. This point is shown that individual propensity than environmental influence is more important. Third, trust was found o have a strong positive effect on power of purchase. Implications of the findings are discussed for researchers and practitioners.

Yucca Ag-aide extracted from Yucca, Agavaceae, is one of the several surface active agents being marked as a soil conditioner for turfgrass. According to the previous research, Yucca can provide an energy source for soil microbes, improve physical properties, and nutrient efficiency in soil, and enhance water infiltration capacity of soil. Yucca was applied to the tee area with cool-season grass showing fairy ring symptom at the Asiana Country Club from June to July, 1999. Yucca was also applied to "Pencross" creeping bentgrass that was stressed by 15 and 30 times of glass stick once every two months(three time total) in 5cm diameter of PVC pipe in greenhouse and to experiment field, established with 35% Tall fescue+50% Kentucky bluegrass+15%Perennial ryegrass at the Kon-kuk University on June 8, 1999. Infiltration at the tee area showing fairy ring symptom was improved by treatment of 250 and 500 fold of Yucca Ag-aide. Yucca Ag-aide treatment also improved root length and dry weight of creeping bentgrass with the stress by glass stick. Coverage and turf quality of cool-season turfgrass in field trial were increased by Yucca Ag-aide. Clipping dry weight was also increased by the treatment.

Idiopathic thrombocytopenic purpura is a disease characterized by thrombocytopenia in peripheral blood with positive anti-platelet antibody titer, no splenomegaly, the presence of megakarocyte. The causes of idiopathic thrombocytopenic purpura were usually related to autoimmune disease, infection and drugs. A 46-years-old man was admitted for evaluation of abdominal mass. He has many cafe-au-lait spots and nodules in almost skin for 30 years. Several years ago, he palpated mass in Lt. inguinal area. hIe has known the abdominal mass after checking abdomen CT in local clinic and visited our hospital for evaluation of abdominal mass. At admission, laboratory tests showed hemoglobin 12.5 g/dL, hematocrit 38.4 %, WBC 5,460 /㎣ (neutrophil 64.5%, lymphocyte 21.7%, monocyte 4.1%, eosinophil 5.4%), reticulocyte 0.7%, Platelet 52,000 /㎣, total protein 6.51 g/dL, albumin 3.80 g/dL, alkaline pohsphatase 161 IU/L, AST 110.7 IU/L, ALT 64.9 IU/L, total bilirubin 0.44 ㎎/dL, BUN 18.4 ㎎/dL, creatinine 0.79 ㎎/dL. Peripheral blood smear showed normocytic normochromic anemia, thrombocytopenia. Bone marrow aspiration smear showed normoplastic myeloid and erythroid precursor. The bone marrow biopsy section shows normocellular marrow (35%) for his age and mildly increasing myeloid cell lineage. We have experienced a case of idiopathic thrombocytopenic purpura in a patient being in neurofibromatosis and therefore reporting it with documentary records. 저자들은 신경섬유종증 환자에서 특별한 원인을 발견할 수 없었음에도 특발성 혈소판 감소증이 발생한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

뇌실이나 뇌기조에 발생하는 포도낭미충증은 매우 드물며 유구조충 유충의 머리부분이 변성되면서 발생하는 낭성 막의 비정상적인 성장을 특징으로 한다. 이러한 유형의 병변은 지름술 후에도 진행적인 경과를 보이며 아직까지 항기생충제를 이용한 치료 사례들이 적고, 따라서 가장 적절한 치료 기간도 알려져 있지 않다. 본 증례 보고는 재발한 실비우스 틈새의 포도낭미충증 환자에서 4주간의 albendazole과 스테로이드로 효과적으로 치료하였던 예이다. 환자는 praziquantel과 뇌복막지름술로 치료를 받고도 포도상의 뇌실질외형의 병변이 악화되어, 뇌척수액 투과가 좋은 것으로 알려진 albendazole로 치료제를 바꾼 뒤 병변의 수와 크기가 감소였으며 이후 2년 간의 추척기간동안 다른 발작 없이 잘 지내고 있다. 지주막하의 포도낭미충증은 albendazole과 corticosteroid 치료에 잘 반응하는 것으로 보인다. The so-called racemose cysticercosis, a rare variety of neurocysticercosis occurring in ventricles or basal cisterns, is characterized by abnormal growth of cystic membranes with degeneration of Taenia solium heads (scolex). Although lesions of this type are known to follow a progressive course even after ventricular shunting, there are limitations of case series treated with antiparasitic drugs, and the optimal duration of the treatment is not yet known. We report a case of relapsed racemose cysticercosis in the Sylvian fissure, who has been successfully treated with albendazole and adjunct corticosteroid for 4 weeks. The patient had been previously treated with praziquantel and ventricul-operitoneal shunt, and maintained on the anticonvulsant drug for one year, but returned to the hospital due to seizure recurrence. The patient has been well in seizure-free state for the follow-up 2 years after albendazole therapy. The subarachnoid racemose cysticercosis seems to respond well to treatment of corticosteroid along with prolonged albendazole.

ATM(Asynchronous Transfer Mode) is a transmission technique for the B-lSDN(Broadband Integrated Service Digital Network). Congestion problems are unavoidable in the ATM networks, since various traffic typos coexist in the networks. The preventive congestion control algorithm is widely used for the real time traffics such as voice and video. The reactive congestion control algorithm works well for the non-real time traffic within a short distance. A mixed traffic control algorithm is proposed, which works either preventively or reactively based on traffic types. The proposed algorithm sets a high and low threshold value at the output buffers and modifies the EPRCA(Enhanced Proportion Rate Control Algorithm) to control loss-sensitive cells. Delay-sensitive cells are handled by the priority control and the UPC(Usage Parameter Control) algorithm. The performance analysis shows that the proposed traffic control algorithm works well for both the VBR(Variab1e Bit Rate) and ABR(Available Bit Rate) traffic with small buffers

Purpose: Protein C and S deficiencies are frequently described as causes of the hypercoagulable states. The aim of this study was to evaluate the clinical features and prognosis of deep venous thrombosis associated with protein C and/or S deficiencies and to determine an adequate treatment modality for such cases. Method: A total of consecutive 42 patients with deep venous thrombosis of the lower extremity were seen in our hospital between September 2000 and August 2002. Hypercoagulability studies were done before systemic anticoagulation therapy, and the diagnosis of protein C and/or S deficiencies was confirmed if antigenic protein C and/or S levels were less than 60%. Result: Seven patients (16.7%) were diagnosed with deep venous thrombosis associated with protein C and/or S deficiencies. Of these, 5 patients with acute iliofemoral deep venous thrombosis were treated with catheter-directed thrombolysis therapy, and 2 with systemic anticoagulation therapy. There were no major complications or clinically detectable pulmonary emboli. Conclusion: Protein C and/or S deficiencies are one of the common causes of deep venous thrombosis. Considering that patients with deep venous thrombosis and protein C and/or S deficiencies should be treated with life-long anticoagulation for the prevention of recurrence, patients presenting with deep venous thrombosis without evidence of other risk factors should be evaluated for hypercoagulable states.
