        The purpose of this treatise is to research for Revivalism of The Korea Evangelical Holiness Church in 1920s, centering round the Four-Fold Gospel. In the 1920s, the society of Korea was changing into the public-centered society, due to the influence of Japanese culture colonization. In this process, Korean churches were trying to rise Revivalism by indirect methods such as enlightenment or social movements. Korean Evangelical Church, However, rose the Revivalism by direct methods like missionary society or revival. The reason was that the leaders of Korean Evangelism Church internalized The Four-Fold Gospel (Regeneration, Sanctification, Divine Healing, Second Coming) as their mission. This is very important point in history of Korea Church. Because modern Korea churches are in standstill and retrogression, this may be the ideal model that Korean churches requests. According to a survey conducted by HANMIJUN(a Preparatory Committee and a New Party), the churches which Korea society wants are the ones which follow Jesus Ministry - full of gospel, miracle and recovery. In this way the Korea evangelical Holiness church in the 1920s had historical value so far, in that they undertook Jesus ministry and led people to salvation. This study used the methods of Literature research, a Research of intelligently history, Social historical study and Psychological research. From these researches you can comprehend internalizing process of Four-Fold Gospel and study all aspects of Revivalism in the 1920s. The research shows that the Four-Fold Gospel has two kinds of cores, Mission and Holy Spirit. First, Regeneration, Sanctification, Divine Healing, and Second Coming are related to mission. So they ought to do mission. And while they were doing mission, they experienced powerful recovery of Holy spirit. In addition, as the early church did, people those who experienced recovery by the Holy Spirit, made their own household and regions evangelical places. All the people in this places experienced Holy spirit from little child to adults, including women, the underprivileged. If people didn't restricted the Holy Spirit, She kept poured to them and while they were praying, the evil ghosts left and the illness was healing. So all of Korea Evangelical Holiness Church members became a pastor, missionary at that time. It is no exaggeration to say that this was the most perfectly adapted form in the 1920s when Korean society were changing to public-centered society. In this atmosphere, The christians of Korea Evangelical Holiness Church in the 1920s growed from 1500 to 3,300, and churches were 20 to 60. Looking at the present situation world church, the Europe and the American's religious communities are declining. But the evangelism church which try to follow the faith of Bible are growing. Because these churches have hopes and peaces which people want to gain. When the churches recovered their the essence, churches start to grow. The Evangelical Holiness Church Revivalism in the 1920s is meaningful, for this point of view. Recovering this essence is always connected with revival. The Korea Churches must listen to the historical facts. Only in that way, the past revival history occurs in our time.

        In this study, fiber mechanical pretreatment before refining was executed with the addition of papermaking additives to find some synergistic effects on fiber property improvement. Three fiber furnishes (SwBKP, KOCC, and BCTMP), and five different additives (CMC, CPAM, PEO, NaOH, Na_(2)O_(2)) were used. It was confirmed again that fiber mechanical pretreatment using Hobart mixer was a special way to modify fiber properties, where fiber WRV (water retention value) increases without losing fiber length. For SwBKP, addition of small amount of CMC (0.2% OD basis), and for KOCC, PEO (0.2% OD basis) caused additional significant improvement of the fiber treatment effects. Other additives, however, did not cause adverse effects on the mechanical pretreatment, or better. For BCTMP, NaOH addition followed by mechanical pretreatment caused more than 20% improvement in tensile and tear strength simultaneously, compared to the control. The yellowing caused by the treatment of NaOH on BCTMP could be minimized by using Na_(2)O_(2) without losing the positive effect of NaOH. The results of this study summarized as follows; 1. Additives gave different effects on different furnishes. No additive was very efficient to all furnishes in the improvement of pretreatment effect. 2. In softwood, mechanical pretreatment with CMC gave better results in tensile and tear strength. CPAM and PEO addition in mechanical pretreatment gave no adverse effects. 3. In the case of KOCC, effect of mechanical pretreatment itself was much greater than the addition of additives. It was assumed that the impurities In KOCC may have caused less effectiveness of the additives. However, NaOH and PEO addition gave some improvement in mechanical pretreatment effect. 4. In BCTMP, only swelling agent gave large changes in its properties. Mechanical pretreatment with NaOH gave high tensile and tear strength more than 20%, compared to the control. 5. In BCTMP, brightness was decreased when NaOH was used. Use of Na_(2)O_(2) caused strength as well as brightness improvement 6. Duration time difference between 1 and 3 hours of mechanical pretreatment did not make significant differences in handsheet strength property development.

      • Data-driven Design Approaches for Vehicle Specification Changes

        The automotive industry is entering a new phase in response to changes in the external environment through the expansion of eco-friendly electric/hydrogen vehicles and the simplification of modules during the manufacturing process. However, in the existing automotive industry, conflicts between structured production guidelines and various stake-holders, who are aligned with periodic production plans, can be problematic. For example, if there is a sudden need to change either production parts or situation-specific designs, it is often difficult for designers to reflect those requirements within the preexisting guidelines. Automotive design includes comprehensive processes that represent the philosophy and ideology of a vehicle, and seeks to derive maximum value from the vehicle specifications. In this study, a system that displays information on parts/module components necessary for real-time design was proposed. Designers will be able to use this system in automotive design processes, based on data from various sources. By applying the system, three channels of information provision were established. These channels will aid in the replacement of specific component parts if an unexpected external problem occurs during the design process, and will help in understanding and using the components in advance. The first approach is to visualize real-time data aggregation in automobile factories using Google Analytics, and to reflect these in “self-growing characters” to be provided to designers. Through this, it is possible to check production and quality status data in real time without the use of complicated labor resources such as command centers. The second approach is to configure the data flow to be able to recognize and analyze the surrounding situation. This is done by applying the vehicle’s camera to the CCTV in the inventory and distribution center, as well as the direction inside the vehicle. Therefore, it is possible to identify and record the parts’ resources and real-time delivery status from the internal camera function without hesitation from existing stakeholders. The final approach is to supply real-time databases of vehicle parts at the site of an accident for on-site repair, using a public API and sensor-based IoT. This allows the designer to obtain information on the behavior of parts to be replaced after accidents involving light contact, so that it can be reflected in the design of the vehicle. The advantage of using these three information channels is that designers can accurately understand and reflect the modules and components that are brought in during the automotive design process. In order to easily compose the interface for the purpose of providing information, the information coming from the three channels is displayed in their respective, case-specific color in the CAD software that designers use in the automobile development process. Its eye tracking usability evaluation makes it easy for business designers to use as well. The improved evaluation process including usability test is also included in this study. The impact of the research is both dashboard application and CAD system as well as data systems from case studies are currently reflected to the design ecosystem of the motors group. 자동차 산업은 친환경 전기/수소 자동차의 확대와 제조 공정에서의 모듈 단순화를 통해서 외부 환경의 변화에 따른 새로운 국면을 맞이하고 있다. 하지만 기존의 자동차 산업에서 구조화된 생산 가이드라인과 기간 단위 생산 계획에 맞춰진 여러 이해관계자들과의 갈등은 변화에 대응하는 방안이 관성과 부딪히는 문제로 나타날 수 있다. 예를 들어, 갑작스럽게 생산에 필요한 부품을 변경해야 하거나 특정 상황에 적용되는 디자인을 변경할 경우, 주어진 가이드라인에 따라 디자이너가 직접 의견을 반영하기 어려운 경우가 많다. 자동차 디자인은 차종의 철학과 이념을 나타내고 해당 차량제원으로 최대의 가치를 끌어내고자 하는 종합적인 과정이다. 본 연구에서는 여러 원천의 데이터를 기반으로 자동차 디자인 과정에서 활용할 수 있도록 디자인에 필요한 부품/모듈 구성요소들에 대한 정보를 실시간으로 표시해주는 시스템을 고안하였다. 이를 적용하여 자동차 디자인 과정에서 예상 못한 외부 문제가 발생했을 때 선택할 구성 부품을 대체하거나 사전에 해당 부품을 이해하고 디자인에 활용할 수 있도록 세 가지 정보 제공 채널을 구성하였다. 첫 번째는 자동차 공장 내 실시간 데이터 집계를 Google Analytics를 활용하여 시각화하고, 이를 공장 자체의 자가 성장 캐릭터에 반영하여 디자이너에게 제공하는 방식이다. 이를 통해 종합상황실 등의 복잡한 인력 체계 없이도 생산 및 품질 현황 데이터를 실시간으로 확인 가능하도록 하였다. 두 번째는 차량용 주차보조 센서 카메라를 차량 부착 뿐만 아니라 인벤토리와 물류센터의 CCTV에도 적용하여 주변상황을 인식하고 분석할 수 있도록 구성하였다. 차량의 조립 생산 단계에서 부품 단위의 이동, 운송, 출하를 거쳐 완성차의 주행 단계에 이르기까지 데이터 흐름을 파악하는 것이 디자인 부문에 필요한 정보를 제공할 수 있는 방법으로 활용되었다. 이를 통해 기존 이해관계자들의 큰 반발 없이 내부의 카메라 기능으로부터 부품 리소스와 운송 상태를 실시간 파악 및 기록 가능하도록 하였다. 마지막으로 공공 API와 센서 기반의 사물인터넷을 활용해서 도로 위 차량 사고가 발생한 위치에서의 현장 수리를 위한 차량 부품 즉시 수급 및 데이터베이스화 방법도 개발 되었다. 이는 디자이너로 하여금 가벼운 접촉 사고에서의 부품 교체 행태에 대한 정보를 얻게 하여 차량의 디자인에 반영 가능하도록 하였다. 시나리오를 바탕으로 이 세 가지 정보 제공 채널을 활용할 경우, 자동차 디자인 과정에서 불러들여오는 부품 및 모듈의 구성 요소들을 디자이너가 정확히 알고 반영할 수 있다는 장점이 부각되었다. 정보 제공의 인터페이스를 쉽게 구성하기 위해서, 실제로 디자이너들이 자동차 개발 과정에서 디자인 프로세스 상에서 활용하는 CAD software에 세 가지 채널들로부터 들어오는 정보를 사례별 컬러로 표시하고, 이를 시선추적 사용성 평가를 통해 현업 디자이너들이 사용하기 쉽게 개선한 과정도 본 연구에 포함시켜 설명하였다.

        Demands for improved fuel consumption efficiency is increasing due to the recent strengthened environmental regulation in the developed nation, which are aimed to meet abnormal climate change due to the global warming and the depletion of natural resources. Now the ways to improve fuel efficiency has been proposed as a lightweight way. That lighter cars was using the lightweight materials such as replacing existing materials, how to improve the strength and toughness it. Aluminum alloy has been popularized the lightweight material in recent years. But magnesium alloys was increasing to the pursuit of high-performance and energy-saving purpose of the machine. The reason that magnesium alloys is lighter than aluminum alloy with specific gravity of 1.74, aluminum (specific gravity 2.70) more than 35 percent lighter. Magnesium also has excellent strength and bending modulus of the automotive and recently have been used in the aircraft parts. The method of cast magnesium had been used to die-casting process. Through die-casting process, the magnesium production weight is decreasing compared with the steel part. Recently, through the die-casting process, only small part of car produce production. And the die-casting process conditions has a lot of impact on the environment. So study of the die-casting process for large products is insignificant. In this paper, the last goal is using the die-casting process that the armrest frame of inner part of commercial buses design the optimal process with the use of lighter material magnesium alloy. Molding conditions set up the most good effect it, the optimal process design of the die-casting process was designed by kind of 18 design of experiments with response surface method(RSM). The optimum casting conditions selected using Design Of Experiment(DOE) and casting analysis is performed. Applied to the process, comparing the results of each experiment conditions and optimum value was found to produce a product. And the product was produced by optimal design. With the products, the X-Ray Inspection tests and three-dimensional measurement were performed. The result of tests is consistent with the analysis results.

        현재 풍력발전은 대기업 중심의 대형 풍력발전기에 의존하고 있다는 것이 문제점이다. 대형 풍력발전기는 긴 날개 끝단의 높은 속도에 의해 소음이 발생하고, 대기업의 큰 투자비에 의해서만 설치가 가능하다는 문제점을 갖고 있으므로, 이를 해소하고, 풍력발전기의 보급을 확대하기 위해서는 저가이며 고효율의 중소형 풍력발전기의 개발이 필요하다. 이에 따라 본 논문에서는 저가이며, 고효율 소형 풍력발전기의 보급형을 개발하고자 저 풍속에서의 다층형 블레이드 및 양문형 날개를 갖는 소형 풍력발전기의 출력 특성에 대한 연구를 수행하였다. 첫째, 저 풍속에서도 발전이 가능한 다층형 구조로 이루어진 블레이드를 소형 풍력발전기에 적용하기 위하여 블레이드의 층수를 1층, 2층 및 3층으로 각각 증가시켰을 때 풍속에 따른 발전기의 출력특성을 분석하였다. 최대풍속 8[m/s]일 때 3층의 블레이드를 적용한 결과 1층 및 2층의 블레이드를 적용할 때보다 발전기 출력전압 33[%] 및 18[%] 증가되었고, 발전기 출력전류 33[%] 및 15[%] 증가되었으며, 발전기 RPM 23[%] 및 13[%] 증가되었다. 분석결과, 다층형 구조를 갖는 블레이드를 소형 풍력발전기에 적용하면 발전기의 출력특성이 상승하고, 저 풍속에서 전기에너지의 발전이 가능함을 확인하였다. 둘째, 저 풍속에서 발전이 가능한 자이로밀형, 힌지형, 양문형 날개들을 소형 수직형 풍력발전기에 적용하여 1[m/s]∼11[m/s]의 풍속변화에 따른 발전기의 출력전압과 출력전류를 분석하였다. 분석결과, 최대풍속 11[m/s]일 때 발전기의 출력전압은 양문형 날개를 적용하면 자이로밀형 날개보다 67[%], 힌지형 날개보다 9[%] 증가되었으며, 발전기 출력전류는 양문형 날개를 적용하면 자이로밀형 날개보다 93[%], 힌지형 날개보다 5[%] 증가되었다. 본 논문을 통해 저 풍속에서 발전이 용이한 양문형 날개의 상승된 출력특성과 실용화의 가능성을 검증하였다. The problem of the present wind power generation is that they rely on wind power generator with massive size which are manufactured mainly by large corporations. Large wind power generate noise due to the high speed of their long wing tips, and are dogged by substantial investment cost due to cumbersome installation process that can be implemented only for large companies. Therefore, it is necessary to develop low-cost, high-efficiency, medium and small-sized wind power generator in order to this problem, thereby enabling individual citizens to have their own wind power generator. Accordingly, dissertation studied the output characteristics of small wind power generator with multi-layered blades and a vertical axis wings, which operate at low wind speeds, in order to develop low-cost and high efficiency small wind power generator. As a first study, rotor blades with multi-layered structure capable of generating power at low wind speeds were applied to small wind power generator, and the output characteristics of the generators according to wind speeds when the layer of blades was increased to 1, 2 and 3 respectively, were analyzed. The analysis results show that the generator’s output voltage rose by 33[%] and 18[%], when the three rotor blades were applied at maximum wind speed of 8[m/s]. Also, the generator output current was increased by 33[%] and 15[%] and the generator RPM by 23[%] and 13[%]. Respectively, rotor blades with multi-layer structure were applied to small wind power generator. It has been confirmed as a result that the output characteristics of the generator were improved and power can be generated even at low wind speeds. As a second study, small vertical axis wind power generator with various wing shapes such as gyromill type, hinge type and double door type wings capable of generating at low wind speeds were used to measure the output voltage and the output current of the generator according to variable wind speed between 1[m/s] and 11[m/s]. As a result, when the maximum wind speed was 11[m/s], the generator output voltage was 67[%] higher than the gyromill type and 9[%] higher than the hinge type wings when the double door type wings was applied. When the double door type wings were applied, the generator output current was increased by 93[%] than the gyromill type wings and by 5[%] than the hinge type wings. It was verify in this study that the double door type wings, which are capable of generating power easily at low wind speeds, has improved output characteristics and high commercial feasibility.
