The Study on the Effect of the Internet Banking Service Quality on Consumer Satisfaction and Reusing Intention Dong-Soo Lee Dept. of Business Administration Graduate School Yeungnam University (Directed by Professor Yeung-Bong Park) Abstract Internet banking is the system where the consumer is offered a variety of financial services through PC and the arrangement of the host computer in the bank. In 1999, the Shinhan bank first started to arrange the internet banking service in Korea. Nowadays, the internet banking is one of the most important services of the bank industries. Because of the evolution and expansion of communication through internet and the merit of internet banking, the share of internet banking in bank is enlarging. Many domestic banks have been deeply interested in the establishment of a strong customer relationship to acquire advantages due to severer competition in bank industries. Customer satisfaction and reusing intention, which as an important strategic goal can be realized through marketing practices, is absolutely crucial for steady and superior economic expansion. Therefore, this study identifies internet banking service quality, customer satisfaction, reusing intention, characteristic of internet banking user. Additionally, investigate the determinants of service quality and empirically investigate relationships among the service quality, customer satisfaction and reusing intention . For this study, existing references regarding service quality, customer satisfaction, and reusing intention were reviewed, and research model was then created. To that end, population that is over 18 years adults using internet banking in Daegu Metropolitan City is established, 250 samples were selected with convenience random sampling method and finally 212 samples were used of this study. After executing pilot study and verifying construct validity and reliability, questionnaire were filled out by the samples with self-adminstration method.

이동수 단국대학교 대학원 2013 국내석사

차량용 전력반도체는 산업용 반도체보다 환경적인 제약이 많아 높은 신뢰성과 안정성을 요구한다. 따라서 차량용 전력반도체 모듈 구성 시 전기적 및 열적 분석을 통한 설계가 필요하다. 본 논문에서는 상용화되어 있는 차량용 Blower Motor 제어 모듈에 대하여 전기적 및 열적 특성을 최적화하는 방법을 제시하였다. 모듈 설계 분야에서 상용화되어 있는 Q3D Extractor 프로그램을 이용하여 배선 간의 기생 임피던스를 추출하고, 열해석 표준 프로그램인 FloTHERM을 이용하여 열적 특성 분석을 수행하였다. 제시한 방법은 비교 실험을 통하여 검증하였으며, 전부하(Full Load) 시 오차범위는 최대 ±4.1%, ±1.6℃의 결과를 얻었다. 또한, 모듈의 전기적 및 구조적 특성을 고려한 열적 최적화 방안을 제시하였다. 이러한 최적화 설계를 위한 방법은 모듈 구동 시 실제 발생할 수 있는 문제를 사전에 분석하고 온도 상승을 예측하여, 차량용 전력반도체 설계 시 유용하게 사용될 수 있다. Power semiconductors for automotive applications require higher reliability and stability than industrial applications because of harsh environmental constraints. In order to minimize the size and weight of power modules, they should be designed with careful consideration for both electrical and thermal characteristics since the reliability of semiconductor heavily depends on the operating temperature. In this paper, the optimizing method for both electrical and thermal characteristics of automotive blower motor control module is proposed using commercially available programs. The extraction of parasitic impedance of power module is accomplished by commercially available Q3D Extractor and the simulation for power estimation of power modules is done by the PSpice program. For thermal analysis, the FloTHERM standard program is used. The proposed approach was validated by the comparison between simulation and experiment results. The proposed design methodology provides very useful solutions for optimizing both electrical and thermal characteristics by reducing design time and efforts to minimize the size and weight of automotive power modules.

As the significance and the number of software components in avionics are increasing, the complexity of airborne software are also increasing. As the result of increasing complexity of airborne software, software errors which are difficult to both detect and fix are hidden in the system. To support detection of hidden errors, airborne system deploys health management system that provides he ability to repair or mitigate errors on a run-time phase. Health management system reveals errors in sequential programs; however, it does not have the ability to detect errors in concurrent programs. Since the behavior of concurrent programs are non-deterministic, the errors in the system are hard to detect and fix. One type of concurrency errors that this works tries to solve is atomicity violation. Atomicity violations, which account for two-thirds of reported concurrency errors, are important because they occur most frequently. Existing researches solve the problem on atomicity violation in two steps: Detection protocol and Recovery engine. The detection protocol decides the rules for storing sequence of thread execution and reports the threads that might violate atomicity of operations. With given information from the protocol, the recovery engine reorders the sequence execution. The overhead of existing approaches are time and space overhead in tracking number of threads and the number of shared variables used in the software system, respectively. We presents AV-HM (Atomicity Violation – Health Management) which predicts an atomicity violation based ideal program execution scenario and stalls an problematic access events. To provide this capability, AV-HM interacts with the ARINC-653 Health Monitor by reporting to the Health Monitor if an atomicity violation was predicted, invoking the repairing engine, and stalling the erroneous execution. The experiment was conducted by measuring the execution time of synthetic programs containing atomicity violation patterns described on bug reports of MySQL, Apache, and Mozilla. The experimental results show that the AV-HM is capable of repairing patterns and reducing time overhead significantly. AV-HM only consumes 1.2 times the program's execution time, allowing for repair of atomicity violations.

이동수 경성대학교 대학원 2011 국내석사

외접 기어 펌프는 넓은 범위에서 유량을 발생시키고, 구조가 간단하면 촢은 응답성의 이점으로 인해 여러 분야의 산업에 광범위 하게 사용되고 있다. 유압기기의 고 정밀 제어특성을 요구하고 있으며, 유체학적 기어의 설계는 고 정밀 제어에 기초가 되는 필수적인 기술이다. 일반적으로 외접기어펌프는 인볼류트 기어가 사용된다. 작동원리는 한 쌍의 맞물린 기어들에 바탕을 둔다. 외접기어 펌프는 구동기어와 종동기어의 이가 맞물리는 압축공간에서 유체의 압력이 급격한 변화를 일으킨다. 이로 인해 토출포트에서 흡입포트로 토출유량 손실이 발생하게 되고 압축공간의 압력이 급격히 증가 하여 기구가 파손되거나 펌프의 운전에 방해하게 된다. 이러한 구동기어와 종동기어 사이에서 발생하는 압력의 급격한 변화를 개선 시키기 위해서는 릴리프 그루브의 위치와 형상을 최적 설계가 필요하다. 본 연구에서는 외접 기어 펌프에서의 구동기어와 종동기어 사이에서 발생하는 압력의 급격한 변화를 완화시키기 위한 릴리프 그루브의 형상설계를 하고, 이를 PumpLinx를 이용한 유체동역학 시뮬레이션을 수행하여 형상과 위치에 따른 압력 변화를 비교하여 그 효용성을 검증하였다.

ABSTRACT The Impact of R&D on Effectiveness in the Hotel Industry Lee, Dong Soo Department of Hotel Management The Graduate School of Tourism Sejong University R&D can be divided into the gradual R&D, which pursues the a little amount of technological development based on the existing knowledge, and the innovative R&D, which tries to discover new knowledge and apply it. Gradual R&D is often easily copied by competitors since it is based on the existing knowledge, but the R&D is hardly copiable since it is often protected by patents or help construct a new market and dominate the area, Because of these benefits R&D provides, many countries or corporations invest a lot in R&D to possess the advantageous position in the new market. Advanced firms already embodies the models for their continuous development by strengthening their core competitiveness with expanding the service sectors or develop more service-like products. R&D in service sectors is already lively in overseas. For example, IBM introduces a new academic discipline called 'Service Science', and both in Germany and Japan, where traditionally manufacturing industry was strong, R&D on service industries is more systematically supported now. In this respect, the hotel business, as a representative form of service industry, provides variety of services in direct connection with customers by human services. Hotel businesses try to find competitiveness not only from accommodation facilities but also by developing customer relationships with differentiated services, and thus have complicated characteristics. However, although those characteristics require more innovative ideas and measuring outcomes from them, few researches have been done on R&D of hotel businesses. Also, there is no clear definition of R&D, and there is few recognition of this problem. This is because the current practices of R&D are more focused on the manufacturing sectors and technologies, and R&D in service industries is also developed and associated with the existing manufacturing sectors. Also, there is few understanding on R&D in hotel businesses as tourist industries. In order to suggest the significance of R&D in hotel businesses. this study tries to find the main variables of R&D, and differentiate the effectiveness of each variable by Analytic Hierarchy Process. By developing indicators to evaluate the suggested R&D and examining the core success factors for the main variables, this study distinguishes the significant factors in R&D, which measures the recognition of R&D among employees working in hotels. By analyzing those core success factors, this study measures the outcomes of R&D and its effectiveness in business. Ultimately it is to throw light on the importance of more systematic R&D in hotel businesses. This study finds following points. First, in order to define R&D in hotel business more systematically, this study derives the evaluative indicators by differentiating the significance of each factor in R&D categorized by AHP. I surveyed 40 people who are related to the R&D in hotel businesses, with strategy, technology, management as the main measuring variables. The relative importance of each variable turned out to be strategy(48), management(37), and technology(20) in order. As detailed indicators, this suggested following indicators of R&D: product development, new service development, hotel information system, pro-environment management, and R&D investment in order of strength. These indicators contribute to establish more appropriate R&D model for hotel businesses since it helps recognize each indicator's different strength. Second, this study conducted factor analysis to measure main success factors in R&D of hotel business. For measuring this, I surveyed 257 employees working at the R&D-related departments in 20 different one or four to five stars hotels. As a result, the main success factors in R&D were human resource development, R&D investment, development of new product & services, IT development, pro-environmental development, and development of interior facilities. As for the main factors for the businesses effectiveness, innovative competitive advantage, and work & organizational efficiency are suggested. The result of testing the first hypothesis concluded that the factors affecting the innovative competitive advantage were development of new products and services, pro-environmental development, human resource development and R&D investment, development in interior facility, and IT development in order of the strength of each factor. As for the work & organizational efficiency, human resource development and R&D investment, IT investment, development of new products and services, pro-environmental development and interior facility in order of effectiveness. Third, this study used business effectiveness in order to measure the outcomes of R&D in hotel businesses, and tries to find if there is difference between the hotel's level or management style. As for the hotel's level, the factors affecting the innovative competitive advantage were interior facilities and pro-environmental development for five-star hotels, and pro-environmental development and human resource development & R&D investment for four-star-hotels. For the factors affecting the work & organizational efficiency, pro-environmental development and human resources development affect five-star hotels more, whereas IT development and new products & services affect the four star hotels more. The differences in hotel's management styles are that, first, the franchised hotels concern pro-environmental development in innovative competitive advantage, while local hotels concern human resources more. As for the work & organizational efficiency, franchised hotels concern IT development while local hotels concern new products and services more.

다가구주택의 건축계획특성에 관한 연구

이동수 명지대학교 대학원 2001 국내석사

현재 우리나라의 다가구주택은 사회적인 변화에 발맞추어 도심지 단독주택지의 주택공급에 일익을 담당하고 있고 기존의 노후한 단독주택들 역시 신축을 통하여 다가구주택으로 전환되어가고 있다. 그럼에도 불구하고 뚜렷한 계획적 지침이나 정책없이 다가구주택 혼재 단독주택지의 거주환경은 갈수록 악화되어 가고 있으며 기존에 가지고 있던 단독주택지의 장점들은 사라져 가고 있다. 여타 다른 주거유형들에 비하여 적절한 규제나 특별한 계획지침 없이 법규적, 경제적 원칙에 의한 민간주도 개발이라는 점에서 그 문제는 더욱 악화되고 있다. 단순히 주택 공급이라는 근시안적인 시각에서 이루어지는 주택개발이 아닌 장기적인 방안에서의 다가구주택에 관한 연구가 필요하다. 그러기에 앞서 시기적으로 변화하는 다가구주택의 경향을 통해 다가구주택의 건축특성에 대한 본질을 이해하는 것이 우선되어야 하겠다. 본 연구에서는 다가구주택의 이해와 일반적인 개발방식, 다가구주택이 가지는 의의와 문제점에 대하여 언급하고 이후, 건축법규적인 측면에서 법규변화와 이에 따른 영향에 대하여 기술하였다. 또한 본문에서는 1990년 다가구주택이 법령으로 제정된 이후 2000년까지 다가구주택의 변화과정을 통한 경향분석을 통하여 다가구주택이 가지고 있는 각시기별 차이와 그 원인을 분석하여 건축특성을 살펴보았다. 이를 위하여 기존 다가구주택 혼재 단독주택중 다가구주택비율이 높은지역을 선정하고, 1990년과 1996년, 2000년의 건축허가도면 101개를 임의로 추출하여 다가구주택의 시기적인 변화와 그 경향에 대하여 분석하였다. 입수한 자료들은 분석항목을 정하고 시기별로 각 항목을 비교분석 하였다. 비교분석결과 다가구주택의 계획상 변화는 다음과 같다. 첫째, 각 시기별 다가구주택의 사례에서 나타나는 부지 및 건물의 형태는 거의 차이가 없다. 세 시기(1990, 1996, 2000) 공히 건물의 형태는 대지의 형태를 따르며 건물의 형태(세장비)는 물리적인 대지조건의 영향을 크게 받는다는 반증이라고 할 수 있다. 이는 다가구주택과 같이 협소한 대지에 단일하게 지어지는 건물에서는 더욱이 계획상의 제약이 따른다. 따라서 다가구주택개발에 있어서 합필을 통한 개발등 보다 융통성 있는 개발방식과 이를 뒷받침해줄 수 있는 정책이 필요하다. 둘째, 평면계획에서 초기 다가구주택에서 보여주었던 동선의 흐름이나 평면계획상의 다양한 패턴들이 이후 좀더 단순화되면서 외부적으로나 내부적으로 불필요한 공간이 없어지고 효율적인 공간으로 대체됨을 보여준다. 이는 보다 많은 수직, 수평 분화를 가능하게 하였고 많은 임대가구를 수용할 수 있게 되었다. 셋째, 다가구주택의 평면형식에 있어서 다양한 계층을 수용할 수 있는 확대가족을 위한 평면개발이 필요하다. 정주인구보다 유동인구에 맞추어진 평면형식은 그 지역의 정주성을 떨어뜨리고 거주환경을 악화시킬 수 있다. 다가구주택은 여러 가지 문제점에도 불구하고 우리의 주거현실에서 어쩔 수 없이 필요한 주거유형으로서 그 건축특성에 대한 이해와 더불어 단독주택지와의 조화를 위한 구체적인 연구가 필요하다. According to the social change, in these days, multi-unit residential building plays on a important role in the housing supply of the single family housing area in the downtown. The single family houses have been converted into multi-unit residential building. In spite of, the existing merits of single residential building area are gradually disappeared. Because the residential environments of the single residential building area are growing worse without the evident guideline or policy in planning. Comparing to the other patterns of residence, multi-unit residential building is growing worse in the problems which are developed by the private without a profitable restriction or special planning guideline. Multi-unit residential buildings demand the studies of the case which is a long-range plan rather than a short-sighted. Above all, the instinctive apprehensions in the architectural character of multi-unit residential building are required. This study refers to the comprehension of multi-unit residential building, the general development method, and the meaning and problem of multi-unit residential building. From now on, this work is describe the legislation change and this influence of the building law. Also, the text looks about the difference per each period and architectural character by analyzing this causes through the change process of multi-unit residential building from 1990s to 2000s. The periodical change of multi-unit residential building and this tendency are analyzed by one hundred one of drawings which is extracted among the permit drawings in 1990's, in 1996's, and in 2000's. The conclusion of the changes in multi-unit residential building are follows; First, the sites and the patterns of buildings are alike. When multi-unit residential building is developed, the flexible development method rather than the existing method is demanded. Second, in the planning, the flowing of move or the various patterns in the planning are more simple and the unnecessary space is replaced with the efficient space. Third, in the plan pattern of multi-unit residential building, the plan development for the expansive family which accepts the variant social stratum is demanded. The multi-unit residential building requires the concrete studies which harmonize these architectural characters with the single residential building area.

평행 구조 메커니즘을 이용한 전자기력 방식의 3자유도 힘/토크 센서에 관한 연구

이동수 연세대학교 대학원 2001 국내석사

다자유도의 힘과 토크를 측정할 수 있는 힘 토크 센서는 조립, 그라인딩, 디버링과 같은 기계가공 작업이나, 일반적인 미세 작업 등 힘 되먹임 제어가 필요한 곳에 유용하게 사용되고 있다. 본 논문에서는 기존의 스트레인 게이지 방식과는 다른 새로운 방식의 힘/ 토크 센서를 제안하였다. 전자석 액추에이터나 자기 베어링에서 많이 사용되는 기전력의 측정을 이용하여 1 자유도의 힘과 2자유도의 토크를 측정할 수 있는 3자유도 힘 토크 센서를 제안하였다. 힘 토크 센서는 일반적인 병렬형 매니퓰레이터의 구조를 갖고 이 매니퓰레이터 형태를 갖는 센서는 각링크마다 영구자석과 전자석이 배치되어 있다. 전체 센서 시스템에 힘과 토크가 가해졌을 때 영구자석과 전자석 사이의 상호 인덕턴스가 변하게 되고 이는 각 링크의 전자석에서 기전력을 발생시킨다. 이러한 힘과 기전력 사이의 상관관계를 이용하여 힘을 찾아내고 각 링크에서의 힘을 자코비안을 이용하여 상판에 작용하는 힘으로 변환시키는 것이 센서의 기본 원리이다. 각 링크 내부에 설치된 영구자석과 전자석의 모델링은 스프링과 댐핑 시스템으로 해석하여 모델링하고 수식적으로 힘과 기전력의 상관관계를 찾았으며, 3자유도 시스템에 적용하였다. 정확한 힘을 주고 이 때의 측정결과를 비교한 결과 정적인 힘의 경우 4.1%, 토크의 경우 8.3%의 오차를 나타냈다. 동적인 힘이 가해졌을 경우에는 힘을 추종하나 오차가 정적인 경우에 비해 크게 나타났다. 정적인 힘 센서로서 힘의 경우 3.08%, 토크의 경우 2.17%의 선형 특성을 나타내었고 힘 센서의 분해능은 0.05N, 0.024Nm이고, 측정 범위는 ±2.5N, ±0.15Nm이며 동적인 힘의 경우 대역폭은 55Hz 이다. In this paper, new type force/torque sensor is presented which is different from the conventional F/T sensors using strain-gauge. This F/T sensor of the manipulator type is composed of the general parallel mechanism and is set permanent magnet and solenoid every link in order. When forces are applied to the suggested F/T sensor, the mutual inductance between permanent magnet and solenoid is changed and the emf is generated by this change in solenoids. Basic principal of sensor is as follows. By using mutual relation of force and emf forces is obtained and is converted into forces added to upper plate using Jacobian. The error of force are 4.1% and the error of torques are 8.3% in case of static forces. In case that a dynamic forces is applied, measured forces traced excited forces. The static force sensor has the 3.08% on force and 2.17% on torque linearity. The resolution is 00.5N, 0.024Nm, and the range of measurement is ±2.5N, ±0.15Nm and its bandwidth to the dynamic force is 55Hz.

비전검사용 자동초점장치의 압흔 검출율 향상에 관한 연구

The purpose of this study is to improve the detection ability of the indentation marks and to enhance the accuracy of the acceptance judgment by acquiring higher quality of the image which is taken from a LCD panel to be inspected in vision inspection area using AOI system during COG process. In order to achieve these goals, this study aims to grasp the control characteristics of the auto-focusing unit, to understand the characteristics of major light sources, and to develop the optimal bonding condition between ACF and electrode patterns. In order to understand the control characteristics of the stepping motor, which is a key part of the Z-axis driver, we reverse-engineered an auto-focusing unit to acquire the knowledge about its structure and operational principle. After that, we developed the Z-axis driver bench tester by ourselves. We confirmed that the displacement error can be reduced by micro stepping mode, through the test of the "axial travel distance according to the step angle". In addition, it is verified that the maximum slewing frequency for determining the axial movement speed can be increased by micro stepping mode. In case of exceeding the maximum slewing frequency under this test, we found that there is an area that is not directly proportional to the axial movement speed. Also, we noticed that there is an unstable operating frequency values which are different from the mechanical resonance phenomenon at some operation frequency values, even though in the direct proportion area . This phenomenon is called to instability. If a system which has the ability of avoiding or controlling such instable band and non-linear response frequency range is developed, the non-linear movement of the Z-axis driver can be eliminated and a clearer image can be obtained. We have experimented to understand the illuminance and luminescence characteristics of halogen lamps, xenon lamps, and LED lamps, which are mainly used in AOI system, with a self-manufactured auto-focusing bench tester. As a result, we found that LED lamps use the lowest electric power and they enable to acquire the clearest image among three light sources. Also, it is confirmed that images acquired from LED lamps show higher accuracy of the acceptance judgment among three light sources, because LED lamps recognize the greatest number of the indentation marks in the electrode-patterned area and the least recognize the indentation marks in the non-patterned area. Regarding the characteristics of the light sources in the imaging region, we found that the LED light source shows uniform brightness over the entire imaging region, so that most regions can be utilized. On the contrary, the halogen light source is darker in the center region and the Xenon light source is darker in the edge region. Due to that, the entire use of the imaging region is inevitably limited. For preventing the blurred image from being generated due to the sudden movement of the auto-focusing unit, it is necessary to develop the bonding condition that allows the thickness of the bonded area to be within the focal depth of the objective lens. If we make it, the operation within the focus range of the auto-focusing unit is enabled. Through experiments with the self-made bonding press , it was verified that the combination of temperature, compression time, and compression pressure can make the bonding thickness within the focal depth of the lens without affecting the conduction at all. Under the experimental conditions of this study, we identified that the optimal bonding condition was 160℃ of temperature, 1 bar of pressure, and 15s of compression time. Finally, we tested the detection capability of the indentation marks and the hit rate of the acceptance judgment about images obtained by the camera and the light source with the self-developed computer program which uses C# language and "simpleblobdetector" function provided by Open CV. It was confirmed that the LED light source is the best light source in both the line scan camera and the local area camera.    Therefore, the data and results obtained from this study will provide useful information for obtaining clearer image data from AOI system, and they will contribute to increase the accuracy of the acceptance judgment and to enhance the inspection ability. Based on the results of this study, further investigations are needed to check the possibility of improving the detection ability and the accuracy of acceptance judgment by changing several parameters in the our program.
