      • ERP 실행에 따른 종업원 만족에 대한 연구

        申洪哲,李顯俊 홍익대학교 경영연구소 2006 경영연구 Vol.31 No.-

        ERP 실행과 종업원 만족에 관한 본 연구의 목적은 다음 두 가지로 요약된다. 첫째, ERP 도입성과에 영향을 미치는 성공요인들에 대한 실증분석을 토대로 향후 ERP를 도입하려는 회사는 물론, 이미 ERP를 도입하였으나 제대로 된 성과를 향유하지 못하는 회사들에게 유용한 가이드라인을 제공하는 것이다. 둘째, ERP 실행과 관련하여 상이한 입장에 놓일 수 있는 정보제공자와 정보이용자간에 만족도 및 만족도에 영향을 미치는 주된 요인들에 대해 지각상 차이를 보이는가를 실증적으로 조사하는 것이다. 이 두 가지의 연구 질문에 대한 답을 위해 ERP에 대한 기존의 문헌연구와 실증 연구를 병행하여 6가지의 가설을 설정하였다. 가설검증에 필요한 자료는 ERP를 실행하고 있는 중소기업 중 총 58개 회사의 116명으로부터 설문조사를 통해 수집하였다. 연구 분석결과 ERP 성과에 영향을 미치는 핵심 성공요인으로는 교육과 훈련 그리고 제공되는 정보의 질 두 가지가 꼽혔다. 이러한 결과는 ERP를 도입하였으나 소기의 성과를 달성하지 못한 기업 및 향후 도입예정인 기업들은 이들 두 요인에 보다 관심을 가질 필요가 있음을 시사한다. 한편, ERP 정보제공자와 이용자의 ERP 만족도는 통계적으로 유의적인 차이를 보이지 않았으며, 지각된 성과로 파악된 ERP 사용자의 개인적 역할이 ERP도입성과에 어떠한 의미 있는 영향을 미칠 것이라는 결론 또한 기각되었다. 반면에, ERP도입성과에 관한 두 유형의 종업원 응답의 평균치를 비교 분석한 결과 정보제공자에 비해 정보이용자의 만족도가 높은 것으로 나타났다. 이는 ERP시스템이 단순 정보입력자 위주의 프로그램이 아니라 정보를 이용하는 사람을 위한 프로그램으로 개발되었고 앞으로도 이용자를 위한 프로그램으로 자리매김 할 것이라는 믿음을 주었다. 본 연구의 결론에서는 연구의 요약, 이론적 공헌, 한계점을 논의하였으며 미래연구에 대한 제안을 하였다. This study examines employees' satisfaction with Enterprise Resource Planning(ERP) Implementation. The purposes of this study can be summarized as below. First, based on field study for success factors which might affect ERP performance, we would like to provide a guideline not only for companies which introduced ERP already but the companies which intend to adopt in a near future. Second, although in the past ERP systems were focused primarily on the provider but now more emphasis should be placed on the user of information. Considering this kind of transition, we compared the satisfactions on the ERP performance between the provider and user of ERP system. To have answers for the two questions mentioned above, literature review on the related references and field study were executed. Based on literature review 6 hypotheses were generated and empirical tests were done based on the survey data which were collected from 58(116 employees) of ERP adopting Small and Medium companies. As a result, training and education as well as the quality of information provided by ERP systems were identified as important success factors. And because of the failure of getting statistically meaningful differences between provider and user on the satisfaction level, this hypothesis was rejected. The comparison of average satisfaction level between two different groups(provider and user of information) resulted in a statistically significant difference, and based on this result we can conclude that ERP system should be introduced primarily for the user not for the provider who is simply inputing information. In addition, based on the empirical results of this study, we are confident to say that programs such as ERP and other related ones that will be introduced in a future should be designed for people who will use or manage information. Theoretical contributions, limitations, and future research directions are discussed at the end of the paper.

      • 고속 주축 상태 모니터링용 광파이버 변위 센서 설계 제작 및 성능평가

        홍준희,박찬규,신우철,이동주 한국공작기계학회 2004 한국공작기계학회 추계학술대회논문집 Vol.2004 No.-

        This paper is focused on practical applicability of the optical fiber sensor considering the machine center which is going to use them. Optical fibers may be fluctuated because the machine center operates as column moving type. This causes distortion of the sensor output signal. To reduce this problem, we have improved the sensor structure and its bracket. And we evaluated performances of the sensor.

        신우철,홍준희,이동주 한국공작기계학회 2003 한국공작기계학회 추계학술대회논문집 Vol.2003 No.-

        Noise is a problem in many electronic circuits and active control system. Arising from spuriously coupled noise from other circuits, it corrupts the signal of interest and introduces an uncertainty into information it contains. In this paper, we have researched noise characteristics of the inductive displacement sensor which has been designed. we first present basic concept and characteristics of magnetic field-coupled noise in the sensor output signal. Then, we are present relation noise and sensor performances. Finally, we concentrate low noise design of a sensor driver and a signal detection circuit.

        인축적 미생물의 인방출과 세포내 저장물질 합성관계

        신응배,김미경,홍준혁,공동수 한국물환경학회 2004 한국물환경학회지 Vol.20 No.6

        Biological phosphorus removal is characterized by complex interactions between different intracellular components of energy as PHA. Therefore, fundamental understanding of the behavior of the intracellular components and their influence on the removal of phosphorus is essential before control strategies to stabilize the proper process. The purpose of this study is to investigate relationship between release of phosphorus and synthesis of intracellular storage polymer. Mass of stored intracellular storage polymer was 21.2 ㎎ PHA/L, 28.8 ㎎ PHA / g MLSS. And phosphorus release/ intracellular storage polymer synthesis rate was 1.8545 ㎎ stored polymer/㎎ Phosphate. In the aerobic phase, mass of PAOs synthesis is 49.37 ㎎ PAOs/L. And PAOs fraction was 6.7-6.9%. Thus intracellular storage polymer synthesis by PAOs is calculated as 493㎎ PHA / g PAOs.

      • 파골세포 활성에 있어 gp130과 PTH의 연관성

        김영준,류현모,김신윤,신홍인 경북대학교 병원 2002 경북대학교병원의학연구소논문집 Vol.6 No.1

        gp130,a subunit for serveral cytokine signal transducing receptors, mediates diverse activities including osteoclastogenesis. In vitro obaervations suggest that PTH also triggers the gp130-mediated signal for bone resorption by stimulating secretion of IL-6,IL-11 and LIF from osteoblast/stromal cells. Though this gp130 signaling is required for full activation of bone resporption by PTH in vitro, the relationship between PTH and gp130 signaling pathway in vitro is not yet clanified. To address the importance of gp130 as a mediator of PTH action in osteoclast activation, the blood ionized calium and blood serum PTH level was investigated in gp130-/- and wild type mice at E18.5 using a CIBA/Coming 634 Ca^+2/pH analyzer and rat intact PTH Kit, respectively.In addition, calium transport efficiency was assessed from gp130 mice at E17.5. The resorptive activity of osteoclasts from intact calvariae by a ^45Ca release assay and the osteoclastic developmental condition in tibiae were also analyzed, respectively.The gp130-/- micerevealed significantly lower ionized calcium level(1.44±0.03 vs1.77±0.03 mmol/ℓ, p<0.001)and significantly higher blood serum PTH(251.8±5.3 VS 20.5±5.3 pg/㎖,p<0.001) compared to wild type littermates.There was no remarkable pathologic change of placenta in gp130-/- and the ^45Ca transport though placenta was accelerated in gp130-/- compared to wild type littermates(%to Het 83%in -/- vs 148% in +/+).The gp130-/- embryos had small skeletons with bones containing little primary spongiosa, and large multinucleated TRAP+ cells along the lower border of the growth plate. Release of ^45Ca from prelableled calvarial bone(E18.5)in response to either 10^-7 M hpTH(1-34)or 20 ng/㎖ sRANKL was lower in gp130-/-calvarial bone compared to gp130+/+ calvarial bone (PTH 1.83±0.6 fold over basal in-/- vs 2.79±0.6 in +/+and sRANKL1.3±0.4 in -/- vs 2.79±0.6 in +/+ and sRANKL1.3±0.4 in -/- vs 2.0±0.4 in +/+,p<0.5). These result strongly support the hypothesis that PTH activates bone resortion,in part, by stimulating ostedtrophic cytokine secretiom from osteoblast/stromal cells, which tirggers gp130-mediated signaling for osteoclastic activation.

        박찬규,신우철,홍준희,이동주 한국공작기계학회 2004 한국공작기계학회 춘계학술대회논문집 Vol.2004 No.-

        This paper is to develop an optical fiber displacement sensor for monitoring high speed spindle. Proper magnitude of optical power as well as amplification of output signal are necessary to improve sensitivity of the sensor. In this paper, to meet the need of improvement of the sensor resolution, we choose proper optical power and amplification level through speculating on optical power of a laser diode.

        박찬규,신우철,배완성,홍준희,이동주 한국공작기계학회 2003 한국공작기계학회 추계학술대회논문집 Vol.2003 No.-

        To make high speed spindle system work properly, sensors with outstanding resolution and dynamic characteristics are essential. An optical fiber displacement sensor is based on simple principles. Electrical signal responds to the optical flux change due to the displacement change between a target and a sensor probe. In this paper, the performance of optical fiber displacement sensor has been investigated according to properties of optical fiber. Firstly, optical loss has been measured before and after polishing optical fiber endface. Secondly, allowance of optical fiber bending has been tested. thirdly sensitivity and linear range of the sensor has been found out according to the shape of cross section of optical fiber.
