  • Standard safety management costs can not be applied to each site with same rate, it is very difficult, because it depends on the experience, work method, work kind, work progress schedule, and hazard level of each construction company. Therefore, this study is to find out hazard level of each work kinds through questionnaire and interview and investigate analyze the status which standard safety management costs have been used. Also, this study is to show reasonable rates of standard safety management costs in construction industry and to set up countermeasures against those problem after reviewing its status in korea with in Japan and Europe. This study is to investigate eleven project kinds of domestic system, first, and to investigate eleven items of apartment bldg, office. Also this study is to investigate and analyze performed costs of presently processing worker finished work so that it shows a new reasonable rate against standard safety management costs in construction industry, in order to make basical data and material to be systemized.

The domestic system of standard safety management costs is not considered in the foreign country, while only related subjective items have been investigated and evaluated for this study. This study is to investigate eleven project kinds of domestic system, first, and to investigate eleven items of apartment bldg, office, civil work such as bridge, tunnel, dam, plant etc, secondly. Additionally, three items of gymnasium, railway, particular steel tower are investigated in this study. Also this study is to investigate and analyze performed costs of presently processing worker finished work so that it shows a new reasonable rate against standard safety management costs in construction industry, in order to make basial data and material to be systemized.

  • Purpose: The purpose of this study was to compare the working status and Standard Shiftwork Index (SSI) between night shift-fixed nurses and rotating shift nurses. Methods: Participants were 367 nurses working as registered nurses at 7 different medical institutions. The data were collected from August 8, 2016 to September 30, 2016. Results: Night shift fixed nurses were more satisfied with work schedule than rotating shift nurses. Rotating shift nurses reported higher SSI scores, such as chronic fatigue, musculoskeletal problems, than night shift fixed nurses. In SSI's sub-items, rotating shift nurses reported higher scores, such as the amount of sleep, feeling well after sleep, heartburn or stomach-ache and heartbeat irregularities, than night shift fixed nurses. Conclusion: The results indicated that night shift fixed system might be an effective method to improve nurses' work satisfaction. It is necessary to figure out any suitable night shift fixed system based on the characteristics of each nursing organization. The SSI might be an useful tool to measure the nurses' satisfaction in reference to their work shift.

  • As a project delivery method, Design-Build (DB) has provided owner, architect, and contractor groups with a process of early design and rapid construction for the past three decades. Although there are many benefits to using standard DB, dissatisfaction has arisen due to limitations to innovate, limited owner involvement during design, and often lengthy procurement. Progressive Design-Build (PDB) has become an appealing alternative providing benefits not seen with standard DB. This paper investigates how PDB impacts a project and how it compares against standard DB; it also presents a proposed framework for evaluating the owner's responsibility and assessment of a project, which we named the "Four Pillars of Project Success". The four pillars are defined with respect to an owner's responsibility and assessment of a project, including project predictability, project risk, project schedule, and project cost. We conducted a literature review, examined several public project case studies, analyzed PDB project information collected by the Design-Build Institute of America (DBIA), and held stakeholder interviews with owners, contractors, and architects who have used both PDB and standard DB. This paper offers insight into PDB's structure and outcomes so an owner group can make an informed decision when considering PDB as their next construction contracting method.

  • The data transmission of MVB(Multifunction Vehicle Bus) of TCN(Train Network Communication) is divided into the periodic transmission phase and the sporadic transmission phase. TCN standard defines the event-polling method for the message transfer in the sporadic phase. However, since the event-polling method does not use pre-scheduling to the priority of the messages to be transmitted, it is inefficient for the real-time systems. To schedule message transmission, a master node should know the priority of message to be transmitted by a slave node prior to the scheduling the sporadic phase, but the existing TCN standard does not support any protocol for this. This paper proposes the slave frame bit-stuffing algorithm, with which a master node gets the necessary information for transmission scheduling and includes the simulation results of the event-polling method and the proposed algorithm.

  • Apartments construction is a one of largest parts in buildings construction. In apartments construction, work interferences are frequently occurred in work processing because workspaces are very various and numerous. However, though work process is important for mainly influencing to the schedule, quality and cost of apartments construction, these work interferences are considered a kind of uncertainty, which is difficult to anticipate at construction planning stage, in work processing. Therefore, this study proposed the measures for work interference reduction in apartment buildings construction and the actual planning for practices. The results can be summarized as follows: (1) the standard of work process is checked regularly. (2) The scope of work and work process is adjusted. (3) The standard of drawings process and cost about work interferences work profess is established.

  • For an industry, production capacity is defined as the maximum level of output that plants can maintain within the framework of a realistic work schedule, taking account of normal downtime, and assuming sufficient availability of inputs to operate machinery and equipment in place. Such capacity is one of the important and basic due to measure, manage and evaluate the production performance and ability of any industrial bodies. However, the estimating methods now in use in Korea are seemed far from the definition above. And there are not any standard estimating method suggested even in the same sort of manufacturing and also no applicable theory for objective and exact measurement. Thus, in this paper, a new measuring model is suggested as standard and supporting theories are developed for general measurement purpose to any manufacturing industries.

  • Endurance test procedures of multipurpose tactical vehicle is constructed by comparing the Korea defence standard and TOP-2-2-506. The plan was to make the best reflect the operational environment and the actual production purposes. Endurance test of multipurpose tactical vehicle more stringent than the existing other military vehicles validation procedures. But the test plan, it is possible to reduce the cost and schedule of long verification that occurs because of the Endurance test. Through a comparison of the dynamic characteristic analysis, change of test center was to ensure the reliability and validity.

  • This paper suggests an environmental improvement scheme for the enactment and revision process of the standard of construction estimation in communication field. The first subject is a simplification of process on the enactment and revision. It can be achieved by transfer the function to the professional board from the subordinate council. The second process is an adoption of tentative step on enactment and revision. And the last subject is creation of maintenance part. All the improvement shall be carried on in long term schedule and on the sufficient financial support from government.
