Pay-for-performance plans are some of widely used human resource practices in many firms, including shipbuilding, for productivity and motivational improvement purposes. Such plans play an important role in industries that are highly labor-intensive, and where effective management of human resources is critical to business operations, such as the shipbuilding industry. Those practices can have large impact on employee performance and ultimately company competitiveness. Research studies that show how such incentive plans improve productivity and reported pattern of adoption by firms have spurred the use and adoption in many firms. However, there are also researchers who point out that there are negative consequences to using incentive plans. Therefore it is important for companies to carefully consider the practices they use. In this paper, I discuss research findings that support the practices and critical viewpoints related to pay-for-performance plans. Research findings from Korean literature are, then, discussed. The shipbuilding industry is chosen because proper human resource management is critical in reducing turnover and increasing employee satisfaction. Through a shipbuilding company case, problems related to using pay-for-performance incentive plans and how they affect work-related issues of employee morale, cooperation, and teamwork will be discussed. While positive aspects have been emphasized to drive greater adoption among firms, the resulting consequences of the pay plans need to be seriously considered and improvements upon the plans made by firms. Improvement suggestions are discussed in the conclusions and implications.

본 연구는 2013년 평가인증 운영체계의 주요 변경내용 8개 항목에 대한 성과를 검토하고 보완점을 모색하고자 보육현장 종사자와 부모, 보육관계자를 대상으로 개선내용의 적절성에 대한 인식비교를 하였다. 보육교직원 200명, 보육담당공무원, 심의위원, 현장관찰자 등 전문가집단 150명, 학부모 144명이 2014년 2월말에 시행된 온라인 설문조사에 참여하였다. 자체점검의 상시화와 소요기간 단축, 기본사항 중 필수항목 확대, 현장관찰일 미고지, 관찰자 파견 수 조정, 재참여수수료 부과 및 참여대상 조정, 확인점검과 인증유효기간 연계 등 8개 항목으로 구성된 대상별 질문문항은 모두 동일하였으나 보육교직원 대상으로 3개 문항이 추가되었다. 빈도, 백분율로 일반적 인식수준을 알아보았으며, 집단별 비교를 위해 1차적으로 집단의 크기가 같은 전문가 세 집단 간 분산분석을 하였고, 통계적 유의차가 없는 경우 2차적으로 세 집단을 하나로 묶은 전문가집단, 보육교직원, 부모의 세 집단을 대상으로 분산분석을 하였다. 분석결과 2013년 평가인증 운영체계 변경내용 각 항목별 집단차이는 있었으나 전체적으로 긍정적인 평가를 하여 주요개정사항들은 적절하고 필요한 조처였다고 판단된다. 그러나 법적준수를 요구하는 기본사항 확인내용 점검과정의 일원화, 유효기간 단축과 불인증, 재참여기회 제한 등 기준점수 미달기관의 관리방안과 현장관찰일 사전고지 및 불시방문에 대한 보육현장의 부담에 대해 좀 더 심도 있는 검토가 필요한 것으로 나타나 이에 대한 개선안을 제언하였다.

Many suggestions is offered to resolve global warming. Tidal current generation is producing power by switched tidal difference sea water horizontal fluid flow produced by tidal difference using rotor and generator. So, change the angle of inflow condition due to the entrance of efficiency are considered. We therefore investigated three dimensional flow analysis and performance evaluation using commercial ANSYS-CFX code for horizontal axis turbine. Then We also studied three dimensional flow characteristics of a rotating rotor and blade surface streamlines around a rotor. As a result, Cp was highest at TSR 5.5, especially the larger changes in the angle of inflow condition decreased efficiency.

모바일 통신의 발전으로 데스크탑과 같이 위치가 고정적인 시스템 외에도 이동이 편리한 휴대폰 등의 모바일 컴퓨팅시스템이 많이 이용되고 있다. 모바일 단말기의 컴퓨팅 성능이 발전하고 있지만, 많은 계산이나 처리를 요구하는 소프트웨어를 휴대폰 같은 모바일 단말기에서 이용하기는 힘들다. 이 같은 단점을 해소하기 위해 모바일 클러스터 컴퓨팅을 활용하기로 하고, 본 연구에서는 기존 모바일 컴퓨팅 시스템을 분석하였지만 기존의 모바일 클러스터 컴퓨팅 연구들에서는 구현보다는 시스템 구조 제안에 머물고 있거나, 실제 휴대폰 등의 단말기로 구현한 예가 없는 등, 현실에서 활용하기에는 무리가 있는 실정이다. 이에 본 논문에서는 기존의 JPVM 클러스터 시스템에 휴대폰이 참여하도록 하고 클러스터 시스템에서 대용량 소프트웨어를 처리하여 휴대폰에서 그 결과를 볼 수 있도록 하였다. JPVM 클러스터에 참여한 휴대폰 상에서는 병렬 응용의 실행과 종료뿐만 아니라 그 실행 결과도 원하는 형태로 볼 수 있다. 구현된 시스템은 휴대폰이 클러스터 시스템에 참여할 수 있다는 측면에서 Mobile-JPVM이라고 할 수 있으며, 성능평가를 통해 Mobile-JPVM이 대용량 소프트웨어를 실행시키는데 문제가 없음을 확인하였다.

Purpose: The purpose of this study is to provide basic data such as development of sustainable support policies and performance management evaluation to support sustainable management of domestic franchises by deriving the sustainable growth cycle of domestic franchises. Research design, data, and methodology: This study is based on systematic review study. We combined search terms such as "Start-up", "Sustainability" and "Success" with four databases, RISS, KISS, e-article and DBpia and searched a total of 1,219 articles published by April 21, 2021. In the process, 35 studies were selected and analyzed after an expert review, excluding documents whose overlapping documents, gray zones (e.g., reports, conference presentations, etc.), degree papers, foreign language literature, and dependent variables were not related to the Sustainability factors. Using ERIS model, which is applied to research on the results of startup, and the franchise's growth cycle, which reflects the growth stage of franchises, we analyzed the factors behind the sustainability of franchise. Result: The results of the study are as follows. First, research on the sustainability of franchise has continued since 2009 in Korea, and has been conducted in various fields such as social welfare in addition to venture, start-up and management. Second, sustainability factors of franchise were analyzed from the ERIS performance model indicating the performance of venture, and the 68 subfactors were derived. Third, it is confirmed that there are important factors that affect the sustainable growth of franchise startups in each franchise's growth cycle. Conclusions: It is significant that through this study, we provided better understanding of the factors that sustain sustainability of franchises, policy suggestions, and presented the direction of future study. Theoretical suggestion is that the main reason for the continuous growth of franchise in each domestic franchise is based on the ERIS performance model. The practical implication is that the headquarters and Franchisor can use it to establish and evaluate performance indicators based on the business growth cycle. The results of this study are expected to be used as basic data for development and performance management evaluation of franchise start-up support policies to support the sustainable management of domestic franchises.

The dynamic performance of railway bridges under high-speed trains draws the attention of bridge engineers. The vibration issue for long-span bridges under high-speed trains is still not well understood due to lack of validations through structural health monitoring (SHM) data. This paper investigates the correlation between bridge acceleration and train speed based on structural dynamics theory and SHM system from three foci. Firstly, the calculated formula of acceleration response under a series of moving load is deduced for the situation that train length is near the length of the bridge span, the correlation between train speed and acceleration amplitude is analyzed. Secondly, the correlation scatterplots of the speed-acceleration is presented and discussed based on the transverse and vertical acceleration response data of Dashengguan Yangtze River Bridge SHM system. Thirdly, the warning indexes of the bridge performance for correlation scatterplots of speed-acceleration are established. The main conclusions are: (1) The resonance between trains and the bridge is unlikely to happen for long-span bridge, but a multimodal correlation curve between train speed and acceleration amplitude exists after the resonance speed; (2) Based on SHM data, multimodal correlation scatterplots of speed-acceleration exist and they have similar trends with the calculated formula; (3) An envelope line of polylines can be used as early warning indicators of the changes of bridge performance due to the changes of slope of envelope line and peak speed of amplitude. This work also gives several suggestions which lay a foundation for the better design, maintenance and long-term monitoring of a long-span high-speed bridge.

This paper aims to study the seismic performance of external diaphragm connection between SST (square steel tube) column and H-shaped beam through experimental and analytical study involving finite element (FE) method and theoretical analysis. In the experimental study, three external diaphragm connection specimens with weak panel zone were tested under axial pressure on the top of the column and antisymmetric cyclic loads at the beam end to investigate the seismic performance of the panel zone. The hysteretic behavior, failure mode, stiffness and ductility of the specimens were discussed. Key point to be explored was the influence of the thickness of the steel tube flange on the shear capacity of the specimens. In the analytical study, three simplified FE models were developed to simulate the seismic behavior of the specimens for further analysis on the influence of steel tube flange. Finally, four existing calculation formulas for the shear capacity of the external diaphragm connection were evaluated through comparisons with the results of experiments and FE analysis, and application suggestions were put forward.
