Hygienic Science is the science for the maintenance and the improvement of human health. Every investigation of hygienic science is originated from practical human life and the fruits of every studies should be recovered and utilized finally by social life. The planning, implementation, evaluation must be carried out by unbiased idea in view of four main aspects in Fig. 1. In the center of that figure you can put any problems that you concern if it is related to health sciences. Today. I want to mention the problem in food and environmental contaminants, referring to some recent status of may country.

Many papers have suggested various models how to decide an optimal time for replacing equipment. In this study, Dynamic Programming is applied to establish a model of replacing equipment and a new algorithm is developed for computerization to meet the increased number of variables. It is possible to predict the real situation with higher accuracy by employing the proposed model including more variables such as planning horizon, original cost, salvage value, decreasing rate, operating and maintenance costs, increasing rate, and so on.

Due to the rapidly changing global business environment and global management environment, companies must actively act for competitiveness. By examining the development process of Enterprise Resource Planning (ERP), there is a chance to optimize the organization and find measures to improve the company competitiveness. It seems examining task process, and studying the influence of ERP introduction to management performance by considering whether the excessive maintenance cost or repetitive investment toward ERP is quiet significant. The companies which instituted ERP uses "business process model" provided by "Best Practice" compare own task to choose much efficient method. This allows simultaneous realization of ERP institution and Business Reengineering (BR).

In this paper, we introduce IEC 60300(Dependability program management) into urban transit system, and propose effective method to apply IEC 60300 to Subway Corporation. The dependability is the collective term used to describe the availability performance and its influencing factors such as reliability performance, maintainability performance and maintenance support performance. A dependability program covers all phases of a system's life cycle from planning to operation and possibly disposal, and is composed of program elements divided into tasks.

우리나라의 인구대비 년간 시멘트 소비량은 최근 10년 동안 평균 1.2ton/인ㆍ년 이상이며, 이는 OECD국가 중 최고의 시멘트 소비 수준인 것으로 알려져 있다. 시멘트ㆍ콘크리트는 강재와는 달리 생산량 전부가 건설재료로 사용되므로 시멘트ㆍ콘크리트가 차지하는 비중이 높고 소비량이 많다는 사실은 구조물의 사용단계에서 요구되는 유지관리비용 중 콘크리트 구조물의 비중이 상대적으로 높을 수밖에 없음을 의미한다.(중략)

The simplified simulation technique for the best generation mix is developed and the studied results are described. The best generation mix over study time from the economic point of view can be easily constructed by this technique. Generator maintenance, the operation of pumpgenerator and LNG thermal generator with limited energy are simulated variously, so a role of each generator is also easily evaluated. Through parametric analysis, useful planning guide points are obtained for the best generation mix transition, nuclear power plant construction cost, ruanium cost , oil cost, coal cost and midnight factor in the study case corresponding to real power system size model.

To construct buildings methods and materials written on the book have been operated and managed with additional program as well as management techniques. However with 2D, a tool which has been used to design a plan, or simple 3D modeling weren't competent enough to plan, design and manage the buildings that are getting complex and higher To solve these problems BIM that enable steps(from planning, designing to maintenance management) to be used as a information is being used.

Information management of products and services in every industries is gaining importance for resource planning and maintenance. In this paper, we analyzed the information classification systems for railway industry. International and domestic classification systems, such as HS, UNSPSC, eCl@ss and ISIC, are reviewed; as a result this paper presents the findings and the various issues. We proposed to-be images in adopting and utilizing the classification systems. Using the integrative information classification systems could make efficient electronic procurement, supply chain management and e-Business of railway services.

The purpose of this study was to investigate and analyze the function and scale on aspect of construction planning with examples of exhibition and convention facilities constructed recently in domestic and foreign area. Also, it was to provide the result for basic data for construction planning and architecture of similar facilities constructed later. The study methodles, but they had characteristics to use the space with compound purpose for exhibition, conference, etc through installing multi-purpose hall. Finally, for effective construction planning of exhibition and convention facilities, it was required to decrease the ratio of common area gradually and derive rationalization of whole space composition by deriving complexity of function rather than planning of single purpose of each facility for exhibition and conference function. was to analyze the characteristics of construction planning for composition and scale of exhibition, conference, public use, support, maintenance functions, etc and placement composition of unit rooms by each floor on the basis of internal area of exhibition and convention facility in Korea and Japan. As the result of analyzing 10 examples(K1~J5), the placement of auditorium and multi-purpose hall was affected according to location of exhibition room and conference room in the composition of unit rooms by each floor and the installment ratio of support facility in Korean examples was higher than in Japanese examples. In case of facility scale, the Japanese examples were overall small in the whole scale relatively to Korean examp.

BIM (Building Information Model) and GIS (Geographic Information System) are applied widely to all stages (Planning - Design - Building - Maintenance) of construction. Recently, research for designing an integrated BIM/GIS platform has been conducted to determine the synergy effects. This paper reports the derivation of BIM/GIS platform application scenarios and definition of specific functions in construction planning and design phases. First, BIM/GIS application scenarios and platform functions are derived for each phase based on an analysis of business affairs. Second, SW functions, which compose platform function, are defined. In the construction planning phase, location selection and route location business affairs were analyzed. Preliminary design and detailed design business affairs were analyzed in the construction design phase. The result of this research can be used for BIM/GIS integrated platform design in the future.
