The standardization of information communication is doing a Internal each other connection and each other characteristic stability operation security in objective. From the low-speed network of the subway operation beginning currently it changes with the superhigh speed digital information transmission communication service environment which is a quality service, the hazard which plans the quality improvement of the efficient communication service use which hits to here and passenger service the standardization of the technical standard which stands and the improvement which hits to an engineering standard and facility must come to accomplish. The facility which existing is been old or the enclosure communication equipments which are insufficient. it improves, establishment itexpands efficiently, like this facilities it is stabilized and it is economic and rationally use maintenance it manages with the plan for the inside and outside of the country information communication relation technical standard and engineering standard service feature improvement and future expandability and economical efficiency, the possibility of having a pliability in order to be, rational technical standard and standard it takes a triangular position, efficient characteristic security of information communication service there is a place objective which promises the rational development of course city railroad communication system with character. Function improvement of enclosure communication base equipment, against an improvement and standardization plan it described trom the prosecution which it sees.

To study of binder and fine aggregate a lot of replacement fly-ash concrete, initial characteristics, standard environment of curing temperature $20^{\circ}C$, hot-weather environment of curing temperature $35^{\circ}C$, . Flesh concrete tested slump. air contest and Hardening concrete valuated setting period of form, day of age 1, 3, 5. 7, 10, 28 compression strength in sealing curing. Purpose of study is consultation materials in field that variety of fly-ash replacement concrete mix proportion comparison and valuation. (1) Experiment result age 28day compression strength more higher plan concrete then standard environment in curing temperature $20^{\circ}C$, , most strength F43 is hot-weather environment in curing temperature $35^{\circ}C$, replacement binder 25%, fine aggregate 15%. (2) Hot-weather environment replacement a mount of fly-ash is a same of plan concrete setting period of form. Age 28day compression strength replacement a mount of fly-ash more hot-weather concrete then plan concrete.

It's became essential that Korea construction companies should enter into the overseas construction market for their growth and sustainability. In order to comply with the client's required global standard and to compete with in the international market, the shifting the construction project management system to global level is required. In accordance with the demand, this paper proposes the top-level document of construction project management system as a to-be model that utilized in overseas construction projects. The project management plan ("PMP") suggested in this paper is not only the most appropriate one, which complies with the global standard, to be used when companies bid for international construction projects against foreign competitors but also has the process modeling and hierarchical structure.

2018년 발사를 목표로 한국항공우주연구원이 개발중인 정지궤도복합위성(GEO-KOMPSAT-2)은 사용되는 발사체에 따라 GTO(Geostationary Transfer Orbit) 혹은 SSTO(Supersynchronous Transfer Orbit)를 거쳐 정지궤도에 진입하게 된다. GTO는 오늘날 대부분의 정지궤도위성이 사용하는 방식인 반면 SSTO의 경우는 사례가 많지 않고 GTO와는 완전히 다른 기술적인 접근이 필요하다. 본 논문에서는 정지궤도복합위성에의 적용을 목표로 SSTO 운용의 제약 사항을 정리하고 SSTO로부터 정지궤도로 진입하기 위한 액체원지점엔진 점화계획을 예비적인 수준에서 구성하였다. 또한 지상추적소의 가시성을 포함한 궤도 시뮬레이션을 수행하여 구성된 계획을 검증하였다.

The purpose of this study is to examinethe present illumination conditions in office environment and to suggest an efficient illumination plan in office planning process. Illumination conditions in work environment were surveyed in 6 offices to investigate whether the present illumination conditions were appropriate to the work type. The results of this study are as follows: Most of the general Illuminance level in the area of work were all at an adequate level, except one. The average Illuminance level in the all meeting rooms were met for the standard. Illuminance in the all reception area were extremely over the standard, The illuminations of this area were rather designed according to the image of the company than the standard. As for the illumination method in the area of general work, four offices used a general lighting by a direct lighting type, while two offices used a general lighting and a task lighting at the same time. This survey suggested that first, each company should consider illumination plan in the building planning process, second, illumination plan considering the type of places is needed, and third, illumination environment may be differentiated according to the work type. In conclusion, efficient illumination environment should be considered in office building planning process, especially In terms of illumination materials and methods.

Current interior lighting design way that is consisting uniformly by designer's experience or simple capacity calculation diversifies according to standard of living elevation and there is problem that do not reflect been individualising resident's change request in lighting plan, design properly. Therefore, because this resident's request, enough judgment data that is worth reflecting dissatisfaction item in design concretely or standard is not saved up in business post, had gotten into bottleneck at lighting design. Diagnose resident's consciousness and feedback degree about interior lighting to existent apartment complex in this research and examined improvement plan. As a result, in the case of illumination, wanted higher brightness and showed reason that is most Affirmativ about order way of lighting fixtures. The reason is because can select registration nine that want by oneself directly. Plan qualitative elevation of house lighting environment making lighting image which is coincided in our real condition, and is thought to reflect various resident's character, fondness in design and solved dissatis faction.

This paper presents a process and operation planning system with an NC code post-processor for effective machining of press dies for production of cars. Based on the machining features, major parts of press dies are categorized into 15 groups and a standard process plan is defined for each group. The standard process plan consists of a series of processes where a process is defined as a group of operations that can be done with one setup. Details such as cutting tools, cutting conditions, and tool paths are decided at the operation planning stage. At the final stage of process and operation planning, the NC code post-processor we developed adjusts feedrates along the tool path to reduce machining time. The adjustment rule is selected based on the metal removal rate estimated by virtually machining with virtual cutting tool.
