In this paper, analysis of the noise induced by rotating machines and the mode analysis of a 3-dimensional enclosure are presented. Adaptive active noise control algorithms for the multi-channel case are proposed. Computer simulations were done to show usefulness of the designed algorithm in a 3-dimensional enclosure case.

The purpose of this study was to analysis to jobs inducing the Musculoskeletal Disorders(MD) and improve the working environment. The case study was conducted at S company where makes radiator case of heavy profile equipment. Most of works are plating and welding. Bending and welding are works which induce MD. The adjustable workstation and fatigue prevention mat were recommended for the welding and bending. A standing posture was recommended for the welding.

In 2014, Seongnam municipal government announced Sanseongro Commercial Area Revitalization including Dandae traditional market with active support of Seongnam municipal government. This study investigated conversion of Dandae market into specialized market to overcome economic stagnation and to make success case of wedding market. The study suggested supplementation of current problems as well as incidental businesses. The study gave SWOT analysis and management reformation to make success case of specialized market and to suggest win-win strategies and development plans to produce wedding market.

Use case diagram is used for defining inter-action between users and systems in object-oriented modeling. It is very important to defining users' requirements for efficient software development. In this paper, we propose a object-oriented modeling process using hierarchical use case analysis for designing class model. First, We define many use case diagrams by several hierarchical modeling level. And next, we can also design class model using the use case diagrams. Our proposed modeling process provides interaction between use case model and class model. That can make us to check the modeling process during the software development. Using the proposed object-oriented modeling we can develop software based on users' requirements. It is very useful for class modeling.

Objectives This study aimed to provide a basis for treatment of soeum person by analysing published case reports and case series in Journal of Sasang Constitutional Medicine.Methods We have reviewed case reports and case series of soeum person in the Journal of Sasang Medicine from 2006 to 2015.Results Of the Twenty-four papers, reporting were reported in twenty-four papers. A total of 13 interventions were described, of which herbal medicine (100%) was most frequently used. Twenty-four papers reported herbal medicine, of which Palmulgunjatang (25%) was most frequently used. A total of 24 Sasang Constitutional Medicine pattern were used in 24 papers, for which soeum person kidney heat affection induced exterior heat disease depression frantic syndrome (25%) was most frequently used.Conclusions A sufficient number of clinical studies are warranted to provide a clinical basis for treatment of soeum person.

In the composite case, the first ply failure is considered total failure of the case. When the case is constructed by filament winding over a metal liner, the first ply failure does not necessarily mean total failure of the case. In this study, we compared the results through finite element analysis and burst test to predict the burst pressure of the hybrid case (filament-wound composite case with metal liner). Through it predicts the burst pressure of the hybrid case, we can determine the thickness of the metal liner and composite.

This paper comparatively analyze to integration case to have a influence detection range estimation about radar cross section in radar system. This paper estimate detection range used to probability of detection in radar equation that used to swerling case 1 in case of radar cross section is small and used to swerling case 3 in case of radar cross section is large. Through simulation, coherent integration and non-coherent integration about swerling case difference were comparatively analyzed. In the result of comparative analysis, non-coherent integration case is outstanding detection range and we known that coherent integration don't suitable for detection range estimation.

The purpose of this paper is to present a procedure for feasibility analysis of new hospitals. The major steps of the procedure proposed consists of determination of location for a new hospital, analysis of the community served, facilities planning, estimation of capital requirements and financial analysis. Technical details of the necessary analyses are covered by providing relevant information most of which is readily available in Korea. The procedure proposed in this paper can be applied not only for the case of the general hospital but also for the case of the clinic.

Flash memory has been increasingly used in handhold devices not only for data storage, but also for code storage. Because NAND flash memory only provides sequential access feature, a traditionally accepted solution to execute the program from NAND flash memory is shadowing. But, shadowing has significant drawbacks increasing a booting time of the system and consuming severe DRAM space. Demand paging has obtained significant attention for program execution from NAND flash memory. But. one of the issues is that there has been no effort to bound demand paging cost in flash memory and to analyze the worst case performance of demand paging. For the worst case timing analysis of programs running from NAND flash memory. the worst case demand paging costs should be estimated. In this paper, we propose two different WCRT analysis methods considering demand paging costs, DP-Pessimistic and DP-Accurate, depending on the accuracy and the complexity of analysis. Also, we compare the accuracy butween DP-Pessimistic and DP-Accurate by using the simulation.
