대장동 도시개발사업을 계기로 부동산 디벨로퍼에 대한 일반인들의 나쁜 인식과 편견이 더욱 심화되는 지경에 이르렀다. 이런 상황에서 디벨로퍼의 인식개선을 위해 연구방법으로 단행본과 논문, 신문기사 등 그리고 일부 대표적인 디벨로퍼의 홈페이지와 인터뷰를 참고로 하고 필자의 수십 년간의 이론과 실무 경험을 통해 디벨로퍼의 의미, 업무사례와 사업추진실태를 분석하였다. 분석결과 디벨로퍼가 어떤 업무를 하는지 추진사업이 얼마나 복잡하고 어려운지를 파악할 수 있었다. 오직 수익만을 추구하여 투기를 일삼는 나쁜 디벨로퍼와 풍성한 삶의 공간과 산업발전에 기여하는 공간의 제공 그리고 지속가능한 도시를 만드는 좋은 디벨로퍼를 구별할 필요가 있다. 이런 사실을 정부, 지자체, 일반 국민들에게 알리어 좋은 디벨로퍼의 부정적인 인식개선에 결정적인 계기가 될 것이다. 1. CONTENTS (1) RESEARCH OBJECTIVES The purpose of this study is to inform the government, local governments, and the public of who the developer is and what the developer is doing through case analysis at a time when the negative image of most real estate developers in Korea is widespread. By doing this, it is intended to improve the negative perception of sound and good developers contributing to human life, urban and community development. (2) RESEARCH METHOD The research method is to analyze and analyze the reality and case of real estate developers based on my 25 years of development experience, graduate school lectures, large companies and real estate CEO courses, and Korea Real Estate Development Association. (3) RESEARCH FINDINGS Developers can improve negative perceptions by promoting and promoting continuous urban spaces, housing, offices, shopping centers, factories, logistics warehouses, and culture through various channels. All citizens should be informed that developers land work, licensing and permits, decision on the sale price, civil complaints, and policy practices are complex and difficult tasks regardless of the morality of developers. The real estate development project is a high-risk, high-yield project, and despite the high probability of high-risk, it is necessary to distinguish between bad developers and sound developers who are obsessed with profits and push ahead with the project. 2. RESULTS It was possible to understand how complex and difficult the project was for developers to do. It is necessary to distinguish between bad developers who invest only in pursuit of profits and good developers who provide rich living spaces and spaces that contribute to industrial development and create sustainable cities. This will be a decisive opportunity to improve the negative perception of good developers by informing the government, local governments, and the general public.

Recently, the emission of hazardous materials (NOx and PM) in diesel engine is a critical issue. The regulations with respect to the NOx and PM are getting stricter, increasingly. Not only the emission problem but also fuel efficiency is considered as a serious issue to develop new turbocharged diesel engines. Thus, currently diesel engines are equipped with exhaust gas recirculation (EGR) and variable geometry turbocharger (VGT). Basically, the diesel engine with EGR and VGT is a highly nonlinear system as well as a Multi-input and multi-output (MIMO) system. Moreover, since EGR and VGT are powered by exhaust gas, severe coupling effect exists. However, conventional Electric Control Unit (ECU) ignores this severe coupling effect and controls the turbocharged diesel engine by using independent single-input single-output (SISO) control methods. Hence, the model based MIMO control method is required not only to treat the coupling effect of EGR and VGT, but also to improve the performance of the engine operation with high fuel economy and low emission level. In this paper, three different model based sliding mode control approaches are proposed to regulate intake manifold pressure (MAP) and exhaust manifold pressure (EXMAP), simultaneously, by controlling exhaust gas recirculation (EGR) flow rate and turbine flow rate. The first approach is high performance robust controller design using nonlinear sliding surface. The second approach is extended input-output linearization for sliding mode control. The third approach is using proportional integral sliding mode control (PISMC) method into turbocharged diesel engine.

Hemming is one of the most important metal forming processes determining external quality of automotive outer panels, such as front and rear door, hood and trunk lid etc. In this study, the flat surface-cove edge hemming process is performed by implicit finite element analysis. A modified edge shape of the panels is suggested and applied to the 3-dimensional simulation by using a commercial code ANSYS. Futhermore, experiments are carried out for aluminium sheet metals to compare with results of analysis.

A ballscrew-linear motion(LM) guide is well-described by its name: it is a LM guide that runs by ballscrew. It consists of LM rail, LM block, end plate, screw, nut and bearing balls. The ballscrew-LM guide has many advantages compared with conventional LM guide. The high efficiency achieved with rolling contact devices permits the employment of antibacklash methods. The balls provide the only physical contact between nut rail and block and ball screw and nut replacing the sliding friction with a rolling motion. The life of the ballscrew-LM is determinated by the balls. The objective of this paper is to introduce the design of the ballscrew-LM with the safety working load.

부동산 개발사업에 관한 단계별 리스크 요인의 상대적 중요도와 효율적인 리스크 관리 방안에 관한 연구

윤영식(Yoon Young Sik),성주한(Sung Joo Han) 한국부동산학회 2014 不動産學報 Vol.59 No.-

본 연구의 목적은 부동산개발사업의 효율적 리스크 관리에 있다. 연구방법은 먼저 개발사업의 단계를 결정하고 각 단계별 리스크 요인의 중요도 순서를 결정하기 위해 도출된 리스크 요인으로 개발전문가들에게 인터뷰를 실시한 후에 이 데이터를 AHP(계층분석) 기법으로 분석하는 것이다. 연구범위는 사적인 디벨로퍼가 개별입지에서 시행하는 모든 종류의 부동산개발사업에 대한 것이다. 연구결과는 4단계에 의한 리스크 중요도의 70%이상이 개발사업 준비단계와 개발사업 착수단계에서 나타났다. 그러므로 개발사업의 성공여부는 개발사업 준비단계와 착수단계에서 결정된다고 판단된다. 각 단계별 분류에 의한 부동산 개발사업에 관한 리스크 요인의 상대적 중요도 항목의 곱으로 나타나는 가중치는 판단의 우선순위를 형성하는 기준을 만든다. 개발사업 전 과정의 가중치 59개 항목 중 톱5 항목은 첫째, 개발업자 자신의 경험과 자금동원능력 그리고 개발사업에 대한 정확히 숙지하지 못하는 것으로 0.08이고, 다음은 사업부지내에 문화재가 묻혀 있어서 사업을 하지 못하거나 지연되는 것으로 0.058이다. 세 번째는 주민의 반대에 의한 사업차질, 네번째는 예비설계나 수지분석을 위한 잘못된 시장분석으로 인한 손익에 영향을 미치는 것이 0.05 등의 순으로 나타났다. 그러므로 상대적 중요한 항목순서에 따라 효율적인 관리를 하여야 한다. 1. CONTENTS (1) RESEARCH OBJECTIVES The purpose of this study is to manage efficiently the risk of real estate development project. (2) RESEARCH METHOD The research method is that first decides the stage of real estate development project and selects the important risk facts of this project. To decide the order of importance for risk fact by stage, after carrying interview for expert developers with the selected risk facts and analysis this data by AHP. (3) RESEARCH FINDINGS The result by four steps is that over 70% of risk importance is appeared in the pre-development project and the beginning stage of development project. Therefore the success or not is depended on the above two stages. 2. RESULTS As a result, the combined weighting by each phase (classification) about real estate development projects with the product of the important value of the item of the relative importance of the Risk factors makes the basis that can form priority of a judgment. The top 5 items of the complex weighted 59 items of entire process is analyzed as follows. Their limits of his experience, developers and funding ability and project plan failed to appreciate exactly, what the best high is appeared for 0.080, and Next with targets, in site cultural assets buried that impossible due to business and project delays on its program to develop appeared for 0.058. Business disruption caused by residents protest appears with 0.051, Market Analysis for conducting preliminary design and budget analysis when completed business development gains and losses caused by a miscalculation of the standings appeared with 0.050 etc. therefore developer must manage efficiently according to the sequence of important risk fact
