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.

Ultrasonic inspection of defects has been focused on the existence of defect in structural material and need has much time and expenses in inspecting all the coordinates (x, y) on material surface. Neural networks is information processing system modeling human brain and can have an application to coordinates (x, y) of defects by multi-point inspection method. Ultrasonic inspection modeling is optimized by neural networks which makes defect echo, back-wall echo and ultrasonic transducer units of input layer and absolute and relative coordinates of defects and defect pattern units of output layer. This method can predict coordinates (x, y) of defects within engineering estimated mean error Ψ.

Robot simulators have been used for the design, analysis, and control of robot systems. Robot simulator have many features such as system modeling, 3D graphic display of model, graphical robot teaching, and off-line programming. In this paper, a robot simulator is proposed which has basic features of robot simulators and some other features to support remote operation. The proposed robot simulator can be used to operate robots in real workplace by using off-line or online simulation and to make human operators learn the operations of robots. In particular, the proposed robot simulator supports a network client/server model for remote operations of robots. By using this feature, human operators can connect his computer system to the server system and control a real robot. The server system has a vision camera to transmit the image of working robots as feedback data to human operators.

This study was conducted to simulate long series of monthly flows by Harmonic synthetic model and to compare with statistical parameters which were derived from synthetic flows and the observed data at two watersheds in the Geum river basin. The results summarized through this study are as follows. 1. Arithmetic mean values of synthetic monthly flows simulated by Harmonic synthetic model are much closer to the results of the observed data in July. On the other side, relative errors for those of the dry season of January, April and December at Gyu Am watershed and January, February, April and December at Gong Ju watershed make a little defference between the observed data and synthetic monthly flows. 2. In comparison with the coefficients of variation, index of fluctuation for monthly flows simulated by Harmonic synthetic models are much closer to the results of the observed data in July. But, relative errors of May and June at Gyu Am and Gong Ju watersheds make a little defference between the observed data and synthetic monthly flows. 3. It was found that synthetic monthly flows based on Harmonic synthetic model are considered to give better results during July and August. But, the other synthetic monthly flows are seemed to be larger than observed data in the applied watersheds. 4. Continuation studies by comparison with other simulation techniques are to be desired for getting reasonable generation technique of synthetic monthly flows for the main river systems in Korea.

This study was conducted to pursue the normalization of frequency distribution by approaching the coefficient of skewness to zero through power transformation to the annual maximum series of four watersheds along Han, Guem, Nag Dong river basin. Analysis for the comparison of design flows according to the return periods were carried out between the best fitted probability distribution and power transformation. The results were analyzed and summarized as follows. 1. Power transformation has found to be best one in comparison with log and square root transformation for being the coefficient of skewness into closer zero as a means of getting the normalization of frequency distribution in the annual maxium series for the applied watersheds. 2. The best fitted probability was acknowledged as three paramater lognormal destribution for Jeong sun of Han, Im Ha of Nag Dong river basin and type 1 extremal distribution for Seok Hwa, Gyu Am of Geum river, respectively. 3. Empirical formulas for the probable flood flows and design flows according to the return periods were derivated for the applied watersheds. 4. Relative errors of three parameter lognormals and type 1 extermal distribution to power transformation which was acknowledged as a best fitted probable flows were shown to be within 10 percent in common for all watersheds from two to two hundred years of return period. 5. The part of higher nonexceedance probabilities, i.e. probable flood flows for power transformation leas found to be more approached to the observed data in comparison with the results of other fitted distributions in view of relative suitability.

Otitis media with effusion (OME) is one of the most common disease in children but its pathogenesis is not clear. In particular the role of allergy has revealed conflicting support with widely varing opinions as to its importance. Within recent years, striking biochemical and immunochemical analytic techniques have opened a new approach the study of otitis media with effusion. So we focused on distributions of IgE in adenoid tissue and serum IgE levels. Authors compared the serum IgE and the distribution of IgE in adenoid tissue between the 20 patients underwent tonsillectomy, adenoidectomy and ventilating tube insertion and control group of 11 patients underwent tonsillectomy and adenoidectomy. The results were as follows; 1. In the distribution of IgE in adenoid tissue, there was a significant increase in the group of patients with OME compared to the control group (P<0.01). 2. In the analysis of serum IgE levels, the levels of IgE in the OME patients an control group were higher than normal level, although the level of IgE in the OME patients were less than that of control group, there was no significance P>0.05).

In this paper, the dynamic stability of a hydraulic excavator using ZMP concept is considered. When a load is moved in an excavator based on automation, an excavator often loses the stability and falls over. This is because a dynamic element is not included in the moment equilibrium equation that is used in order to judge a reversal. Consequently, reversal distinction algorithm including all a static and a dynamic element along a load movement in crane work is necessary. Zero Moment Point(ZMP) is a point on the floor where the resultant moment of the gravity, the inertial force of the manipulator and the external force is zero. This study is going to interpret the reversal stability of the excavator to which is applied ZMP concept through simulation.
