        루이스 칸의 스케치 분석을 통한 예일영국미술센터의 기본형식에 관한 연구

        오광석,전영훈,안웅희 대한건축학회지회연합회 2009 대한건축학회연합논문집 Vol.11 No.2

        The purpose of this study is to understand the meaning of Louis I. Kahn's “"Form”" drawing, in which his principal thought is immanent, through a detailed analysis of his sketches and writings of the Yale Center for British Arts. The basic form is the organization of the plan around two courts and it is expressive of the dual nature of the program. The basic form is maintained through the whole design process and it also plays an important role in controlling the relationship between program requirements and formal transformations. It is derived from the consideration of the human activities in the museum and it is based on the idea that this museum would create the intimate relationship between visitors and the works of art.

      • I발표장 : 촉매 및 반응공학3 ; I-62 : High-throughput screening of NO SCR quarternary catalysts containing Pt, Cu, Fe and Co supported on mesoporous AlSBA-15

        오광석,박용기,우성일 한국화학공학회 2007 화학공학의이론과응용 Vol.10 No.1

        The selective catalytic reduction (SCR) of NOx with hydrocarbons in excess oxygen has been studied extensively in recent years. As a candidate, Pt/ZSM-5 and Cu/ZSM-5 catalysts have been suggested due to the high deNOx activity and selectivity. However, they are suffered from N2O formation or deactivation in the presence of water or sulphur and a further improvement is required. Nowadays, a combinatorial screening approach has been tried to optimize the composition in multicomponent deNOx catalyst systems. That is, binary or quaternary combinations of catalyst libraries were synthesized and their catalytic performances were tested in multi-channel reactor. In this study, we tried to optimize catalytic composition in a quaternary system of Pt, Cu, Fe, and Co supported on aluminium-containing SBA-15 using a 64-channel micro reactor.

        자율주행 개인화를 위한 순환 최소자승 기반 융합형 주행특성 구분 알고리즘

        오광석 한국융합학회 2017 한국융합학회논문지 Vol.8 No.9

        본 논문은 자율주행 개인화를 위한 순환 최소자승 기반 융합형 종방향 주행특성 구분 알고리즘에 관한 연구이다. 최근 자율주행 기술은 Level 4 완전 자율주행 단계를 위해 다양한 연구가 수행되고 있다. 자율주행 자동차의 상용화를 위해서는 탑승자의 자율주행에 대한 이질감을 최소화할 수 있어야 하며 이를 위해 자율주행 개인화 기술이 필요하다. 이 문제를 해결하기 위해 본 연구에서는 운전자의 종방향 주행특성을 수학적으로 표현하고 순환 최소자승 기법 기반 실 주행 데이터를 이용하여 주행특성을 도출하는 알고리즘을 제안하였다. 두 명의 실제 운전자 데이터를 이용하여 종방향 주행특성을 도출하였으며 두 명의 운전자를 구분하기 위해 가설검정 기반 확률적 구분 알고리즘을 적용하였다. 제안된 종방향 주행특성 도출 및 구분 알고리즘은 개별 운전자의 주행특성을 합리적으로 나타낼 수 있었으며 가설검정 기반 확률적 구분기법에 의해 주행특성이 구분될 수 있음을 확인하였다. This paper describes a recursive least-squares based convergent algorithm for driving characteristic classification for personalized autonomous driving. Recently, various researches on autonomous driving technology have been conducted for level 4 fully autonomous driving. In order for commercialization of the autonomous vehicle, personalized autonomous driving is required to minimize passenger’s insecureness to the autonomous vehicle. To address this problem. this study proposes mathematical model that represents driving characteristics and recursive least-squares based algorithm that can estimate the defined characteristics. The actual data of two drivers has been used to derive driving characteristics and the hypothesis testing method has been used to classify two drivers. It is shown that the proposed algorithms can derive driving characteristics and classify two drivers reasonably.

        “원시교회(Ecclesia Primitiva)” 개념과 이상에 대한 역사적 고찰

        오광석 한국교회사학회 2010 韓國敎會史學會誌 Vol.27 No.-

        In the history of the church, there have always been both a quest for the true church and a call for personal and communal reform and renewal. Most frequently the predominant model for this reform and renewal was the ecclesia primitiva. The notion of the ecclesia primitiva in the church history has most frequently referred to the apostolic church as portrayed in such New Testament passages as Acts 4:32ff, but has sometimes been extended to cover either the pre-Constantinian church or the whole patristic period. The first known use of the term ecclesia primitiva dates at least from the fifth century. One may find occasional references to the idea of the ecclesia primitiva in Merovingian documents. Also, during the Carolingian period, the idea of the ecclesia primitiva remained and was used primarily to signify the ideals of the common and apostolic life. The idea was current, especially among those groups interested in the reform of monastic and canonical life. The use of the term ecclesia primitiva is seldom found in the tenth-century documents but the idea remained and was widely revived in the middle of the eleventh century and later on was used to promote the ideal of monastic and canonical reform. The idea of the ecclesia primitiva was also associated with the search for the most perfect form of the Christian life. The idea became so common by the middle of the twelfth century that sometimes it was simply used to refer to the institutions believed to have existed in the early church, very occasionally implying that in the early church Christianity had not achieved the fullness of its development. In general the idea of the ecclesia primitiva in the Middle Ages was most commonly associated with the following of the apostolic life and the practice of having all things in common and living a simple and communal life. The reform on the model of the primitive church has been a primary motive for dissent since the early Middle Ages. Reformation, especially of the Anabaptists, was the culmination of the efforts to restore the primitive church. The ecclesia primitiva has been the model for the reform and renewal toward the true church within Protestantism as well as within Catholicism throughout the history of Christianity.

        전통의 사람 존 웨슬리 -기독교 전통 안에서의 웨슬리 교회론 이해

        오광석 한국교회사학회 2009 韓國敎會史學會誌 Vol.24 No.-

        This study investigates John Wesley’s ecclesiology (or his understanding of church, ministry, and sacraments) in the Christian tradition. John Wesley, the founder of Methodism, was a man of tradition. He inherited his rich legacy from various traditions, and the traditions were instrumental in shaping his ecclesiology. The major traditions on which he drew include primitivism, Anglicanism, Puritanism, and Pietism. He also, though not heavily, drew on the mystics of the Roman Catholicism and indirectly on the reformers. Primitive Christianity offered Wesley an ideal of the church and a model for his personal religious life and Methodist movement. The medieval mysticism, with its stress on inward religion and selfdiscipline, was influential upon Wesley, and its influence lasted throughout his life. Although there is no evidence of medieval Catholicism’s direct influence upon Wesley’s ecclesiology, the character of Wesley’s United Societies is akin to that of Tertiaries of medieval Catholicism in that they were both designed to be auxiliary to the parent body. Wesley drew certain themes such as sanctification and discipline from the reformers indirectly through the Anglican and Puritan traditions. The Anglican tradition was the initial influence upon and a lasting contribution to Wesley’s ecclesiology. Particularly the early Wesley was attached to the High-Church Anglican churchmanship and was enthusiastic to share in its sacramental life and to induce others to do the same. His High-Church Anglicanism, however, clashed with the evangelical conversion of 1738, and later was overshadowed by the combined influence of Puritanism and Pietism. From the Puritans Wesley drew an image of the Christian disciplined life and the instructions in its practice. Puritanism was also a main contributor to Wesley’s unorthodox churchmanship after he became a field preacher in 1739. From the Pietists Wesley learned the importance of the role and training of laity and was impressed by their discipline and enthusiasm for mission. The particular influence of the Pietists was most prominent in the creation and development of Methodist Church organization. Pietism also permanently influenced Wesley’s soteriology, in relation to which he established the character and validity of his ecclesiology. In a sense, Wesley’s ecclesiology was an amalgam of the multiple traditions that he inherited and sought to appropriate in a creative eclecticism. Investigating the historical sources which assisted Wesley in shaping his ecclesiology, this study examines Wesley’s doctrine of church as a whole in relation to the concept of salvation, since soteriology took the central place in his understanding of church. Wesley, with his highly developed sense of mission, shaped and developed his evangelical, functional understanding of church, responding to the spiritual needs of the people he sought to serve.
