  • Method of remodeling builder selection for remodeling is competitive bidding. also metropolitan city, megalopolis city, city more than 50million have to do basic plan for remodeling before establishment of a housing cooperative. Purpose of basic plan is improvement of living conditions & the Quality of Life for resident. Technical Proposal Tendering in spite of being the a reasonable bidding system, institutional part, appraisal standard and the item part, consider procedure pard is performed in a similar way to the existing bidding system. so, technical proposal tendering is appropriate for future Method of builder selection of remodeling. therefore, the study purpose is a evaluation element of technical proposal tendering for apartment remodeling business The methods of study is understanding concept through review of precedent literature. Next, case investigation through Analysis of focal points. Lastly, evaluation element deduction of technical proposal tendering for apartment remodeling business through specialist conversation. As a result, Alteration of a right & move management is added to evaluation element's professional field. And detail item is alteration of a right & move management.

  • This paper deals with the feasibility analysis and alternatives for infrared detector development. The purpose of this paper analyze development requirement and feasibility study in both technology and cost. We get raw input data for system engineering process from development and technical expert, and then analyze cost and technology for development feasibility, and alternative study. Infrared Detector is core component of Thermal Imaging System and developed by ADD from 2006 to 2008 year. Technical level is analyzed by TRL(Technical Readiness Level) and AOA(Analysis of Alternative) is done by development and production cost estimate. We use SEER-H tool for cost estimate, that is parametric cost estimate tool based on Knowledge Base. Also this paper presents risk analysis for project management because it is necessary to risk driver management during the infrared detector development. The result of IR Detector feasibility and alternative study will be used in technical and cost analysis. This study can help those who are related to the cost analysis and development feasibility of other weapons

  • Results of free and bound myo-inositol in infant formula (IF) are presented. Inositol was analyzed by HILIC ultra-performance liquid chromatography coupled with mass spectrometer. The levels of free myo-inositol in 27 Australian and 4 EU originated IF samples were 300-600 mg/kg of powder or 1.6-3.1 mg/100 kJ. The amount of bound inositol in lipid fraction of IF was, on average, 10% of free myo-inositol.

  • The properties of paper are very susceptible to moisture content originated from relative humidity. This propensity of PVA impregnated paper was investigated in this study. Especially the hardening effect of borax treatment after PVA impregnation on the response of paper sample to the relative humidity was evaluated. When the moisture content was increased with the relative humidity, tensile stretch and tear resistance were increased while tensile strength and stiffness were decreased. A great increase in folding endurance of PVA impregnated paper sample was found at the higher relative humidity. The borax treatment could reduce the response of PVA impregated paper to the relative humidity.

  • In order to improve the speed of railway, several parameters and/or technical issues, which are affecting speed improvement negatively, need to be considered in addition to the enhancement of physical performance of the railway system such as maximum speed, speed at curve, and speed at turnout track. The parameters under complicated situation of railway system are from the areas of rolling stocks, track, power system, signalling, etc. In general, two different aspects of technical issues can be evaluated; Technical issues in the hardware aspect and technical issues in the software aspect. The hardware parameters include running performance, braking performance, and power performance, while the software factors are rules, regulations, and riding quality. In this investigation, a comparison study between hardware and software aspects in technical issues was conducted to provide technical information on the amendment of railway speed-up regulations.

  • In this study, to show well favorable characteristics of warm forged material, we compared and analyzed microstructure and mechanical properties of general hot-forged material which finished heat treatment with warm-forged material which was produced by control cooling condition. Along with this, we suggested better direction of control cooling condition to be able to remove heat treatment process while satisfying mechanical properties.

  • In this paper, development of TIM Module for constructing PDM will be introduced. Technical information relevant product data influences cost, quality, precision and productivity. One of the very important feature of product data is organizing not by oneself but very closed to many technical information such as document, file, image and analysis sheet. To manage various technical information, several kinds of management system are used in multi level of production system. PDM and TIM systems are being developed for suitable purpose and are in need of Network technology, Information Technology, Database, sharing and distributing information. Developed TIM system is based on Web environment. By using this system, we can manage systematic technical information and reduce cost for constructing PDM system. And also we will put to practical use another technical information management system for mold plant.

  • 현재 제정 중에 있는 한국전기규정(KEC)은 국제전기표준인 IEC를 기반으로 제정 중에 있으며, 이에 따라 과거의 기준과 다른 IEC 기반의 전선 굵기, 차단용량, 접지방법 등을 적용할 수 있게 되었다. 그중에서 전선의 굵기와 차단기의 차단용량과 관련된 사항은 이미 국내 기술기준에 반영되어 적용되고 있다. 그러나 접지방법 및 체계에 대한 사항은 아직도 적용을 위해 충분하게 논의되지 않은 상태이다. 따라서 IEC를 기반으로 시설된 전기설비의 검증방안을 모색하여 KEC의 조기정착 및 전기설비안전을 확보하고자 한다.

  • Safety accident rate of small-medium construction site is high. because of lack of safety management system, lack of safety management capacity, lack of investment for safety, Owner's insufficient awareness about safety. In order to improve this, Currently in Occupational Safety and Health Act, Construction site of amounts more than 300 million won less than 120 billion (architectural),150 billion won(civil) mandatory subject to the technical guidance on construction accident prevention. Context of construction accident causes with construction accident rate relationship analysis and case analysis of technical guidance, through a survey of stakeholders in the technical guidance drawn the problems of the construction accident prevention technical guidance system and ways to improve on this.
