Construction companies are fulfilled in according to project, and it is difficult to execute the standardized process in various construction projects. Thus many construction companies is adopting BPM(Business Process Management) that meet business process change and business improvement. However, it is difficult to apply BPM in a lump because of difference of BPM characteristics and company's strategies. For this reason, it is desirable to select business process based on company's priority. This study indicated need of method for selecting business process through studying current researches, and made BPA for construction company by analyzing business process in construction company. Moreover, this study indicated core business process from a point of profitability and growth view through grasping strategic goal priority. And also, it proposed criteria for process evaluation for BPM adoption, evaluated core business process, and indicated prior business process for BPM adoption.

Recently construction companies expand position for apartment house in construction market because of house supply rate increase and its amount. In addition, because the focus of house sale market has moved to customer from supplier, the importance of defect management is being issued currently. However, current apartment defect management is not satisfied with customer's demand for the lack of business process management, management organization, information feedback, and readiness for defect in construction phase. To solve this problem, this study proposed business process management improvement model for defect management. Proposed improvement model make information feedback, defect management business quality improvement, and improper process improvement through integrating defect management and quality management. It is expected to contribute to customer's satisfaction improvement and reliance improvement for construction companies.

Touch screen technologies are widely used as the basic input for mobile devices. However, for smartphones, touch screens have been utilized as a simple device that merely process text data. It has been considered an inappropriate multimedia input device for one to use design applications, such as painting, due to its narrow touch screen space, which makes it inconvenient to draw pictures. In this study, we propose to enhance this weakness by using infrared approach on a smartphone's input interface. The usage of infrared approach will allow for quick and accurate operations without facing any space constraints. In this paper, we provide a detailed description of the design and implementation of a smartphone user interface using infrared pointing device. Additionally, using experimental results, we prove that our proposed approach is more convenient and efficient than traditional touch screen approaches used in smartphones.

기존의 드론 조작은 초보자에게 어려웠다. 초보자의 경우 드론을 조종하다가 드론이 추락하거나 장애물에 걸려 프로펠러 등의 부품들이 손상되는 경우를 빈번하게 마주한다. 본 연구에서는 초보자 또한 드론 파손의 걱정 없이 드론의 조작을 더욱 쉽게 개선시키는 것을 전제로 뇌파와 보조입력인 음성인식을 이용한 드론 컨트롤러 기술을 적용하고자 한다. 현재 대중적으로 출시되어 있는 드론의 경우 호버링 기능을 포함시켜 드론의 추락 위험을 줄여주는 기능을 탑재하고 있다. 하지만 속도가 빠른 드론의 조작에 있어 미숙한 초보자들은 장애물과의 충돌 그리고 드론 착륙 시 기체손상 등의 위험에 대비하기 힘들다. 본 논문은 이러한 문제점들을 개선하기 위해 기존의 드론 컨트롤러 대신 특정한 동작을 상상할 때 발현되는 동작상상뇌파와 음성입력을 적용한 '동작상상뇌파와 음성인식을 이용한 드론 컨트롤러' 기술을 제안한다. 기존의 드론 컨트롤러와는 다르게 빅 데이터 처리기술인 머신러닝을 이용하여 뇌파 데이터를 처리하고 그 데이터들과 입력되는 뇌파 값을 비교하여 드론을 제어한다. 또한 뇌파의 발현이 안정적이지 못하는 상황을 대비한 보조입력인 음성인식을 이용하여 드론의 기체손상을 최소화 시킬 수 있다.

This research investigated the feasibility of incorporating industrial by-products into precast concrete formulated with blast furnace slag and natural gypsum. Specifically, the study examined the effects of incorporating steelmaking slag(STS slag), combined heat power plant fly ash, and return dust. The optimal amount of these by-products was determined by measuring air content, slump, and compressive strength at various incorporation levels. Results demonstrated that compressive strength was enhanced across all levels of by-product addition. Notably, incorporating 10% of the by-products led to exceptional early-age strength development. However, a 20% addition of combined heat power plant ash significantly reduced the slump value by approximately 40%. Considering these findings and the requirement for rapid strength development in precast concrete applications, a 10% incorporation of industrial by-products was deemed optimal due to its ability to accelerate early-age strength gain.

The Accommodational missionary method adopted by the Jesuit missionaries who came to China in the late Ming and early Qing dynasty is called the Accommodation and Naturalization and is based on the Poetry. The terms they borrowed were 'Di(Emperor Above)' and 'Tian(The heaven)', the key terms of Confucianism. Although 'Di' was a new transcendent concept, its status was downgraded in the political upheaval, and 'Tian' was rather elevated. However, both of these concepts gradually transformed into philosophical concepts that directly affect real life. The two terms borrowed to express the priesthood could not contain the uniqueness of Christianity, and Christianity was interpreted as an extension line of Confucianism thinking, reduced to an adjunct of Confucianism, and was not indigenous to the depth of ideology. A rational philosophical inquiry could not have played a full role in guiding the Chinese into the true Christian 'faith' unless it is paired with the great teachings of revelation. It is necessary to analyze these results soberly to find problems and to try various studies to explore ways to open up new horizon for Christian missionary work.

This study analysed the narrative of and , two history documentary broadcasted on KBS, in terms of story-telling and discourse. And it also examined whether TV as mass media could provide an alternative interpretation against the dominant historical awareness. As a result, both programmes showed limitations on representing subversive point of view to the dominant ideology. At the story-telling level, firstly, they represented in a way of male-hero narrative though they were describing the history of woman, and while representing woman as a public figure they eliminated her feminity and individuality. Secondly, before evaluating woman as a historic figure they previously appreciated her appearance in a male-point of view. Thirdly, although they were telling the story of woman in a political view, they focused on love triangle, therefore failed to make her as a public figure. The discourses of both programmes were anchoring the existing historical interpretation instead of offering an alternative historical imagination. The narrator who were telling history at the studio in a omniscient viewpoint took a role as a meaning definer, placed at the highest rank in the hierarchy of discourse structure. Especially in , the dramatized images to cover lack of visual data helped anchor the patriarchal narrative and reduced the possibility of subversive interpretation on historic figure.

The roles of the characters of 3D animation Toystory3, which was released in 2010 and achieved worldwide success, can be classified into typical, simple and easy-to-understand roles such as hero, villain, princess, and assistant. However, the process, in which each character's role is finally recognized by the audience, is embodied in a very colorful and exquisite manner and makes the curiosity of the audience continue effectively. The stream of the diverse role changes of the characters of Toystory3 is represented through "visual rhythm of the lighting design" and such rhythm can be confirmed most clearly in the digital colorscript stage. This researcher analyzed the characters' role changes in the work based on Propp's folktale character analysis theory, and extracted the core scenes that lead to inference, doubt, performance, reinforcement by character in order to grasp how the audience gasps major characters' role changes. The visual differences of the lighting design, which the four core scenes of each character show, were represented in graph and analyzed, and the results showed that the changes that one character has constituted rhythmical, visual contrast gradually and the rhythms of each independent character achieve visual contrast and harmony each other like the voice part of polyphony. This researcher calls this "the visual counterpoint of character's changing" and derives the conclusion that a dual visual counterpoint is hidden in the character production of the full-length animation Toystory3. Along with this, this researcher proposes the production of full-length animation that actively utilizes constructive aesthetics.
