        조직 구성원들의 연봉제 수용성

        정화향(Zheng Hua Xiang),이정원(Lee Jeong Won),장은미(Chang Eun mi) 한국인사관리학회 2016 조직과 인사관리연구 Vol.40 No.2

        연봉제의 도입과 실행은 조직 차원의 변화이기에 구성원들의 수용성에 따라 그 효과는 달라진다. 그럼에도 불구하고, 제도의 도입 혹은 실행과정에서 구성원의 수용성에 대한 연구, 특히 수용에 있어 중요하게 여겨지는 회사와 구성원들 사이에서 이루어지는 정보 교환 또는 커뮤니케이션의 효과를 다루는 연구는 매우 드물다. 본 연구는 최근 사회적으로 다시 불거진 연봉제 실효성에대한 논의와 관련하여, 정보 교환(information exchange) 관점에서 조직 구성원들의 연봉제 수용성에 대한 기존의 연구를 확장하고자 한다. 연봉제의 수용성은 제도 특성 자체에 대한 인지는 물론, 제도와 관련된 조직과 구성원 간 정보 교환 및 비대칭 현상이 매우 중요하다는 시각에서, 신호이론(signaling theory)과 불확실성 감소이론(uncertainty reduction theory)을 기반으로, 연봉제 관련 커뮤니케이션이 연봉제 수용성에 미치는 효과를 규명하고자 하였다. 이를 위해 최근 10년 안에 연봉제를 도입한 18개 기업의 199명 직원들을 대상으로 데이터를 수집하여 분석을 실시하였다. 분석 결과, 연봉제의 특성(성과급 비율의 적정성 인지)은 연봉제 수용성(도구성 인지 및 정서적 몰입) 중 정서적 몰입에 긍정적 영향을 미치는 반면, 신호 이론에 기반을 둔 정보제공 적절성에 대한 인지는 구성원들의 연봉제 수용성인 도구성 인지 및 정서적 몰입에 모두 긍정적인 영향을 미치는 것으로 나타났다. 또한 성과급 비율의 적정성 인지와 조직구성원들의 정보추구행동이 상호작용하여 연봉제 수용성 중 정서적 몰입에 긍정적 영향을 미치는 것으로 나타났다. Implementing individual pay for performance(individual P4P) is an organizational level institutional change. Thus, its effectiveness depends on the employee acceptance of the practice. However, in wage system study, research on employee acceptance of individual P4P, and especially the role of information exchange or communication between organization and employees, is limited until today. The current research, based on signaling theory and uncertainty reduction theory, explored the predictors of employee acceptance of individual P4P. This study examined the effects of the perceived propriety of incentive intensity and individual P4P-related communication, and the interaction effects of perceived the propriety of incentive intensity and individual P4P-related communication on employee acceptance of individual P4P (perceived instrumentality and affective commitment). This thesis used a sample from both private and public enterprises which are implementing individual P4P in Korea. Statistical analysis results indicated that the perceived propriety of incentive intensity was significantly and positively correlated with affective commitment to individual P4P, and the perceived the quality of information was significantly and positively associated with both on perceived instrumentality and affective commitment of employee acceptance of individual P4P. The interaction effects of the perceived propriety of incentive intensity and information seeking behavior on affective commitment to P4P was significant as well.

      • 센서구동 방식에 의한 태양추적 시스템

        박정국,최연옥,조금배,최창주 조선대학교 에너지.자원신기술연구소 2004 에너지·자원신기술연구소 논문지 Vol.26 No.2

        Nowaday, almost of practical energy comes from the fossil fuel, such as coal, oil and gas. But those methode causes the environmental pollution. Photovoltaic systems are considered as a alternative energy source to overcome the shortage of electricity in the future. Photovoltaic system is easier to operate and maintain than the other power generating system since it generally contains no moving parts, operate silently and require very little maintenance. In this paper, it is proposed 150[W] solar tracking system, the system designed as the normal line of the solar cell always runs parallel the ray of the sun. This design can minimize the cosign loss of the system.

      • 중국거주 조선족 여성의 영적 안녕정도가 정신건강에 미치는 영향

        정성덕,이종범,김진성,서완석,배대석,박순재,주열,염형욱,김승원,김구묘,안영록,황대홍,표미자,조창열,정태길 영남대학교 의과대학 2004 Yeungnam University Journal of Medicine Vol.21 No.2

        자아초월 정신의학이 체계화되면서 영성(spirituality)은 인성의 한 부분이라는 이론이 대두되었는데 이 영성은 정신건강에 큰 영향을 미친다고 했다. 인간의 성향 중 영적 안녕 정도를 파악하여 그 정도가 정신건강 중 허위성 경향, 정신병적 경향 및 불안과 우울 경향 등에 어떠한 영향을 미치는지를 조사하고저 본 연구를 실시하였다. 대상은 중국의 연변 조선족 자치구에 거주하는 여성 400명을 대상으로 하여 한국판 영적 안녕척도를 사용하여 영적 안녕정도를 파악하였다. 영적 안녕척도의 총점과 이 척도의 2개 하위 척도인 종교적 안녕과 실존적 안녕 척도 양자로 평가한 성적이 불안-우울통합척도와 정신분열증 척도 및 허위성 척도로 평가한 성적에 미치는 영향을 검증하기 위하여 상관관계분석 및 회기분석을 실시하였다. 그 결과는 다음과 같다. 1) 영적 안녕척도로 평가한 조선족 여성의 총점은 68.29로 한국의 기독교 여성이 평가한 100.65보다 훨씬 낮은 점수였다. 2) 불안·우울통합척도로 평가한 총점은 44.88로 연변노인이 평가한 점수와 일개지역의 한국농촌주민이 평가한 점수와 비슷한 결과였다. 3) 허위성 척도로 평가한 성적은 평균 74.57로 70점 이상이 86%(344명)이었으나 영적 안녕 성적과 허위성 성적 간에는 유의한 상관이 없었다. 4) 영적 안녕총점은 정신분열증 척도로 평가한 정신병적 경향에 유의한 영향을 미치지 않았으나 종교적 안녕하위척도의 성적은 정신병적 경향을 높여준데 비하여 실존적 안녕하위척도의 성적은 정신병적 경향을 낮게 해주었다. 5) 영적 안녕척도의 총점 및 두 하위척도인종교적 안녕과 실존적 안녕은 불안과 우울에유의한 상관을 보였는데 영적 안녕총점이 높을수록 불안·우울 총점이 다소 낮아지는 경향을 보였다. 6) 종교적 안녕 하위척도와 불안과 우울과의 관계는 종교적 안녕점수가 높을수록 불안과 우울을 각각 다소 유의하게 높여주었으며 이에 비하여 실존적 안녕하위척도와 불안과 우울과의 관계는 실존적 안녕정도가 높을수록 불안 및 우울점수는 유의하게 낮아졌다. 이와 같은 성적을 미루어볼 때 연변에 거주하는 조선족 여성이 평가한 영적 안녕정도는 정신병적 경향과 불안 및 우울에 유의한 상관을 보였으면 이 척도의 하위 척도인 종교적 안녕정도는 정신건강에 부정적인 영향을 미치는 반면 실존적 안녕정도는 정신건강에 긍정적 영향을 미친 결과로 평가되었다. 이러한 결과는 공산주의 사회에서 실존적 안녕은 긍정적인 가치관으로 평가되는 반면 종교적 안녕은 정신건강에 부정적으로 작용한 것을 입증해 주었다고 하겠다. Background: Spirituality has been an important part of Transpersonal Psychology and is believed to have a large effect on the mental health because it has been systematized. The aim of this study was to determine the level of spiritual disposition on human beings along with its effects on one's mental health. Materials and Methods: The study targeted 400 women residing in Youn-Gil city of JiLin Prov., which is a district of the Cho-Sun tribe in China. Their spiritual well-being was studied using the Spiritual Well-being Scale-Korean Version. The spiritual well-being scale consists of 2 sub-scales of religious well-being and existential well-being. The study was evaluated using a lie scale, psychotic trend, and a combined anxiety-depression scale. The results were considered to be factors of one's mental health. The correlation between the spiritual well-being and each tendency was analyzed by regression analysis. Results: The total score of the Cho-Sun tribal women according to the spiritual well-being scale was 68.29 which was much less than the 100.65 of Korean Christian women. There was no significant correlation between the spiritual well-being and the Lie trend. However, it was found that 86%(344) of Cho-Sun tribal women scored above 70 in the Lie trend with a mean score of 74.57 which is higher than normal populations. Regarding the correlation between the spiritual well-being and psychotic trend, the psychotic trend became significantly higher when the religious well-being was at a high level. On the other hand, the psychotic trend became significantly lower when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and anxiety, the anxiety was significantly higher when the religious well-being was at a high level. However, the anxiety level was significantly low when the existential well-being was at a high level. Regarding the correlation between the spiritual well-being and depression, the depression level was somewhat significantly high when the religious well-being was at a high level. However, the depression level was significantly low when the existential well-being was at a high level. Conclusion: This study evaluated the effects of spiritual well-being on a person's mental health among Cho-Sun tribal women in Youn-Gil city of JiLIn Prov., P.R. of China. The results found that the religious well-being, which is a sub-scale of spiritual well-being, had negative effects while the existential well-being had positive effects on the mental health. These results proved that a person's religious disposition had negative effects on their mental health in a communitarian society.

        Experimental Validation of Numerical Model for Turbulent Flow in a Tangentially Fired Boiler with Platen Reheaters

        Zheng, Chang-Hao,Xu, Xu-Chang,Park, Jong-Wook The Korean Society of Mechanical Engineers 2003 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.17 No.1

        A 1 : 20 laboratory scale test rig of a 200 MW tangentially fired boiler is built up with completely simulated structures such as platen heaters and burners. Iso-thermal turbulent flow in the boiler is mapped by 3-D PDA (Particle Dynamic Analyzer). The 3-D numerical models for the same case are proposed based on the solution of к-$\varepsilon$ model closed RANS (Reynolds time-Averaged Navier-Stokes) equations, which are written in the framework of general coordinates and discretized in the corresponding body-fitted meshes. Not only are the grid lines arranged to fit the inner/outer boundaries. but also to align with the streamlines to the best possibility in order to reduce the NDE (numerical diffusion errors). Extensive comparisons of profiles of mean velocities are carried out between experiment and calculation. Predicted velocities in burner region were quantitatively similar with measured ones, while those in other area have same tendency with experimental counterpart.

        Finite-Time Nonlinear Disturbance Observer Based Discretized Integral Sliding Mode Control for PMSM Drives

        Chang-Ming Zheng,Jiasheng Zhang 전력전자학회 2018 JOURNAL OF POWER ELECTRONICS Vol.18 No.4

        To deal with the operation performance degradation of permanent magnet synchronous machine (PMSM) drives with uncertainties and unmodeled dynamics, this paper presents a finite-time nonlinear disturbance observer (FTNDO) based discretized integral sliding mode (DISM) composite control scheme. Based on the reaching-law approach, a DISM speed controller featuring a superior dynamic quality and global robustness against disturbances is constructed. This controller can avoid the reaching phase and overlarge control action. In addition, a sliding mode differentiator based FTNDO is devised and extended to the discrete-time domain for disturbance estimation. The attractive features of the FTNDO are that it can provide a finite-time converging estimation and alleviate the chattering effect in conventional sliding mode observers, while retaining robustness to parameter variations. By feeding the estimate forward to the pre-stage DISM controller, both disturbances and chattering can be significantly suppressed. Moreover, considering the estimation error of a FTNDO caused by discrete sampling, a stability analysis of the composite controller is discussed. Experimental results validate the superiority of the presented scheme.

      • Fatty acid synthesis is a target for antibacterial activity of unsaturated fatty acids

        Zheng, Chang Ji,Yoo, Jung-Sung,Lee, Tae-Gyu,Cho, Hee-Young,Kim, Young-Ho,Kim, Won-Gon Elsevier 2005 FEBS letters Vol.579 No.23

        <P><B>Abstract</B></P><P>Long-chain unsaturated fatty acids, such as linoleic acid, show antibacterial activity and are the key ingredients of antimicrobial food additives and some antibacterial herbs. However, the precise mechanism for this antimicrobial activity remains unclear. We found that linoleic acid inhibited bacterial enoyl-acyl carrier protein reductase (FabI), an essential component of bacterial fatty acid synthesis, which has served as a promising target for antibacterial drugs. Additional unsaturated fatty acids including palmitoleic acid, oleic acid, linolenic acid, and arachidonic acid also exhibited the inhibition of FabI. However, neither the saturated form (stearic acid) nor the methyl ester of linoleic acid inhibited FabI. These FabI-inhibitory activities of various fatty acids and their derivatives very well correlated with the inhibition of fatty acid biosynthesis using [<SUP>14</SUP>C] acetate incorporation assay, and importantly, also correlated with antibacterial activity. Furthermore, the supplementation with exogenous fatty acids reversed the antibacterial effect of linoleic acid, which showing that it target fatty acid synthesis. Our data demonstrate for the first time that the antibacterial action of unsaturated fatty acids is mediated by the inhibition of fatty acid synthesis.</P>

        Flat-bottomed design philosophy of Y-typed bifurcations in hydropower stations

        Chang-zheng Shi,Yang Wang,He-gao Wu,Qi-ling Zhang,Kai Su 국제구조공학회 2016 Structural Engineering and Mechanics, An Int'l Jou Vol.57 No.6

        The drainage problem in bifurcations causes pecuniary losses when hydropower stations are undergoing periodic overhaul. A new design philosophy for Y-typed bifurcations that are flat-bottomed is proposed. The bottoms of all pipe sections are located at the same level, making drainage due to gravity possible and shortening the draining time. All fundamental curves were determined, and contrastive analysis with a crescent-rib reinforced bifurcation in an actual project was conducted. Feasibility demonstrations were researched including structural characteristics based on finite element modeling and hydraulic characteristics based on computational fluid dynamics. The new bifurcation provided a well-balanced shape and reasonable stress state. It did not worsen the flow characteristics, and the head loss was considered acceptable. The proposed Y-typed bifurcation was shown to be suitable for pumped storage power stations
