金柱煥,曺圭澄 慶北大學校 齒科大學 1984 慶北齒大論文集 Vol.1 No.1
This statistical study was made to evaluate the state of the pulp and to clinically assist the treatment by measuring the average voltages of the teeth. The author have studied on the pulp responses to the electric pulp tester (pyo.Cure)in permanent anterior teeth of the 297 adults above 20. The results were as follows; In responses between the teeth of the male and female, male's was higher than female's (in maxilla:male 36.86 volt, female 31.68v, in mandible: male 34.49v, female 33.57v), and so the responses were statistically significant (p < 0.05). The difference in responses between the teeth of upper and lower jaws showed no statistical significance. The difference in responses between the teeth of the right and left were not statistically significant. The responses of the teeth were slightly increased from central incisor to canine, but there was a statistical significance between lateral incisor and canine but not between central incisor and lateral incisor. The responses of the teeth were slightly decreased in proportion to aging after 40.

金周煥,金昌煥 東國大學校 1990 論文集 Vol.29 No.-
Hills must be needed to understand landform of Korea because they hold a high rate in the Korea. Specially, from a landform viewpoint as life environment, the understand about hills are very important. Meanwhile, hillslope is one of the important parts in landforms that is consisted of slope. Therefore, the purpose of this research is that analyze slope distribution of hills and that make on offer basic data of hills. The studied areas are Naju in Chollanam-do, Korea. An administrative divisions are Naju-shi, Maju-gun and the south part of Changsong-gun, the western part of Kwangju-jik' alshi. The method of this study is mainly indoor survey. The result of this study are as follows: ※ Slope angles under 20° are especially common in the Naju hills. ※ Slope angles are higher in the area of volcanic, sedimetary and metamorphic rocks than in the area of granite. ※ The mean slope angle in the Naju hills 10.19° that looks moderate or moderaltely steep. ※ Compared with plains and mountains, the Naju hills have steep or gentle slope, respecitively. ※ The slope distribution in the Naju hills are transitional form of plains and mounatins.

이기종 유사홀로그램 시스템 간 콘텐츠 자동 가시화 기법
김주환,조동식,Kim, Ju-Hwan,Jo, DongSik 한국정보통신학회 2020 한국정보통신학회논문지 Vol.24 No.11
최근 실감 콘텐츠 체험 기회를 제공하기 위한 유사홀로그램(hologram-like)시스템은 공연, 전시, 교육 등에 활발히 적용 및 서비스되고 있다. 이러한 유사홀로그램 시스템을 구성하는 방법은 피라미드형, 반투명 대형 단일 스크린 형태 등 설치될 장소, 사용 목적, 체험자 인원, 콘텐츠의 형태 등에 따라 다양한 크기, 투영 면수 등으로 구성할 수 있다. 본 논문에서는 형태가 서로 다른 이기종의 유사홀로그램 시스템에서 구동되는 실감 콘텐츠 제작을 용이하게 하기 위해 하드웨어 구성에 맞추어 즉석에서 자동적으로 가시화할 수 있는 기법을 제시한다. 본 논문의 결과에 따르면 유사홀로그램 시스템의 구성에 따라 콘텐츠를 매뉴얼하게 재가공하는 노력이 필요 없이 콘텐츠 개발자는 유사홀로그램 시스템에 투영되는 콘텐츠만을 개발하면 즉석에서 자동으로 보정된 가시화가 진행됨을 알 수가 있었다. Recently, a hologram-like system to provide a realistic experience has been serviced in performances, exhibitions, education. The constructing method for the hologram-like system can be configured in various forms such as a pyramid-typed, a semi-transparent large screen form. However, in various types of hologram-like systems, it is difficult to provide adjustment by changing and revising the content according to the configured hardware characteristics. In this paper, we propose a novel technique that can automatically visualize virtual contents running on heterogeneous hologram-like systems. To change the content to a given hardware configuration, we receive pre-built simple text-based configuration data, and correcting process was performed. According to the results of this paper, we found automatically and easily corrected visualization with the given configuration of the hologram-like system. Also, the problem of reducing the time by manual control in various types of heterogeneous hologram systems was solved.
