The study suggests a contract model of application operation through case study of A bank's IT outsourcing application contract based on workload. The IT outsourcing order form has a problem in that the scope of work is ambiguous due to the integration of operation and maintenance. In this study, application operation and maintenance were separated by referring to application operation history provided in ISO/IEC15504-5 standard. The scope of the IT outsourcing service was clarified by organizing the definition and detail activities of the application operation business. Application operation contract method has generally applied estimation method by the number of input manpower and period by agreement between buyer and client. As there is no activity to calculate the number of input manpower based on the operational work history and based on the standard workload per activity. In this case is not guaranteed due to the simple agreement between the contractors. In this paper, we propose an application operating cost estimation model that measures the size of the operating software using function point analysis that is the basis of application operation tasks. In order to verify the validity of the application operation cost model, we verified the correlation between the application size and the labor cost through regression analysis using SPSS.

시간적 금전적 압박으로 최근의 웹 응용에서는 체계적인 시험작업이 종종 간과되곤 한다. 게다가 효과적인 웹 응용 시험 방법이 많지 않아 웹 응용에 기존의 시험 방법들을 적용하면서 개발자들은 많은 어려움을 겪고 있다. 빠르고 효과적 인 시험을 위하여 웹 페이지간의 메시지를 모델링한 UML 순차도(Sequence Diagram)로부터 웹 응용을 위한 시험사례를 추출하는 방법을 제안한다. 웹 응용을 위한 시험사례들은 UML의 순차도에서 자기 호출 메시지 (Self-Call Messages)를 포함한 메시지들로부터 추출된다. 시험사례는 시험할 대상인 메시지와 스크립트 함수, 서버 페이지와 추가적인 시험값들로 구성된다. 또한, 웹 응용 시험을 지원하기 위한 간단한 도구를 제시한다. 이 시험 도구는 웹 응용을 시험하기 위한 URL을 생성하고 이를 실행하여 그 결과를 보인다. 생성된 URL은 시험할 서버 페이지의 주소와 추가적인 시험값들로 구성된다. 이 도구는 마이크로소프트 비주얼 베이직으로 작성하였다. 회원 관리 기능을 수행하는 웹 응용개발 과제에 제안하는 시험사례 추출방법과 시험 지원 도구를 적용하였으며 그 유용성을 확인하였다.

The application of T.B.M tunnelling has been progressively increased since the first entrance into Korea in 1985 and especially, its higher performance and safety is widely proved as a generalized tunnelling in hardrock tunnel construction, comparing wi th conventional method. This case announcement will be much helpful for your general understanding of T.B.M tunnelling and the development of tunneling technology by introducing the brief methods and construction results from the actual application cases of T.B.M tunnelling in Ulsan Water Supply Tunnel Project, the longest tunnel in Korea under construction by YOU ONE.

The current test methods are insufficient to evaluate and ensure the safety and reliability of vehicle system for all possible dynamic situation including the worst case such as rollover, spin-out and so on. Although the known NHTSA J-turn and Fish-hook steering maneuvers are applied for the vehicle performance assessment, they aren't enough to estimate other possible worst case scenarios. Therefore, it is crucial for us to verify the various worst cases including the existing severe steering maneuvers. This paper includes the procedure to search for other useful worst case based upon the existing worst case scenarios mentioned above and its application in simulation basis. The only human steering angle is selected as a design parameter here and optimized to maximize the index function to be expressed in terms of either roll angle or yaw rate. The obtained scenarios were enough to generate the worst case to meet NHTSA worst case definition (ex.2-inch wheel lift). Additionally, as an application, the worst case steering maneuver is acquired for the vehicle to operate with a simple ESP system. It has been concluded that the new procedure in this paper is adequate to create other feasible worst case scenarios for a vehicle system both with an intelligent safety control system and without it.

In many existing studies, the analyses on the application and effect of the project-based learning model (PBL), a student-centered teaching and learning strategy, have been emphasized and carried out in various majors and courses. This case study analyzes the effects of applying a project-based learning model to the engineering accounting course for engineering students in 2021 in the context of the COVID-19 pandemic, compared with the offline course in 2019 and the simple online course in 2020. Project team consisting of 2-3 students carried out online collaborative learning activities for solving open-ended problems through the 5-step PBL procedure including presenting the final result. Except for this online PBL application in 2021, textbooks, lecture contents, assignments, and tests were implemented the same for each semester for three years. Through lecture evaluation and survey by students, the online PBL application semester showed higher effects in inducing student-centered learning, lecture satisfaction, and student competency improvement compared to the non-applying semesters, further, it was evaluated that the online PBL application to the course and evaluation method were more appropriate than other semesters. It is expected that the online PBL method and operation procedure applied in this study can be utilized as a best practice for the design and operation of various online courses for student-centered collaborative learning activities and educational effects.

A photograph, which was applied to contemporary art, plays a very important role in the whole of the multiplied and diversified contemporary arts today. The application of photos, which were shown in contemporary art following the 1950s, can be classified into five types according to role and function of a photo in the process of developing a work. However, this classification is shown a little ambiguously. That is because photos of being utilized by artists are indicated very diversely depending on their artistic strategy and situation. As the first type, a few painters utilize a photo as mirror of reality in order to materialize a challenging and revolutionary idea with going against traditional picture in their pictorial practice. As the second classification, especially American painters utilize a photo as material component of forming their picture like photo-montage or collage. The combined application of this medium is first doing genre de-construction and hybridization of post-modernism in the 1980s while ultimately aiming at social criticism or political satire. The third type implies particularly a case that avant-garde artists utilize a photo as evidence of a work. In this case, a photo is employed as evidence of a work, which disappears in the temporal space essentially like body art, land art, and performance. Also, as the fourth type is a case of utilizing a photo for artistic concept of a work, not pictorial practice of picture, it is utilized often as important artistic strategy of conceptual artists. The final type of utilizing photo is a case of applying photo as formative tool on behalf of dye-stuffs or crayon in order to record a section of reality, which always continues regardless of event or meaning any more, in the traditional picture. In this case, a work is indicated as a photo of having a form of picture, namely, as Forme-tableau. The main subject is indicated there as a daily case of being repeated always the extremely common and revived theme.
