What is culture-products? Culture-products contains identity of nation and region. French critic Guy Sorman says "It is natural that buying culture-products when you travel any countries" Culture-products which contains our own cultural factors will give positive image of country. The research and development of grafting grudge experience culture-products was advanced the characteristic of area-culture that necessary is prerequisite. We need to develop culture-products which mixed regional culture and characteristic. We would like to research about Baekje culture and culture-products and sales products in museum. Museum is one of the tourist's attractions and great place to express regional factors. The culture-products are specially limited in the products which reflects a Baekje culture with Muryeong's tomb in Gong-ju and Baekje incense burner in Bu-Yeo it advanced. We hope that this research could help to understand market of culture-products and development.

Currently, the depth of cracks is measured using ultrasonic detectors in maintenance practice. This method consists of measuring the depth of cracks by attaching ultrasonic depth measuring equipment to the concrete surface, and there are restrictions on the timing and location of the inspection. These limitations can be addressed through the development of image-based crack depth measurement AI technology. If crack depth measurements are made based on images, restrictions on the timing and location of inspections can be lifted because images acquired with simple filming equipment can be used as input information. To efficiently develop these artificial intelligence technologies, it is essential to identify the interrelationship between crack depth measurements and image characteristic information. Thus, this study is a basic study of the development of image-based crack depth measurement AI technology and aims to identify image characteristic information related to crack depth.

This study was surveyed the knowledge and attitude toward the elderly in dental personnels, who play an important role in oral health of the elderly in the aging society, In order to arrange the basic data that is conducive to development in the mouth care of the elderly, the research was conducted from January 7 to February 14, 2008, targeting 270 dental personnels in Daejeon & Chungnam area, who are in charge of oral duties in the current clinic. As a result of analyzing so that questionnaire can be prepared with the self-administered questionnaire, the following results were obtained 1. The knowledge level on the elderly in dental hygienist was 13.47 marks out of 25-mark perfection. There was no difference in knowledge depending on job category and volunteer-work activity experience, And, there was no difference even depending on physical & physiological sphere, psychological sphere, and family & social sphere. 2. The attitude level toward the elderly in dental hygienist was 91.63 marks out of 150-mark perfection. Dental hygienist showed positive attitude in personality characteristic, emotional characteristic, and self-management ability by sphere, and showed statistically significant difference (p=0.011). 3. In case of having volunteer-work activity experience, the attitude level toward the elderly was 92.57 marks out of 150-mark perfection, A case of having volunteer-work activity experience showed positive tendency in emotional characteristic, self-management ability, and judgement-ability characteristic by sphere, And, the attitude toward family relation was indicated to be negative tendency, thus there was statistical significance(p=0.022). 4. As for the correlation between knowledge and attitude toward the elderly, dental hygienist was indicated to have high interest in the volunteer-work experience, the elderly education experience, and the elderly problem(r=0. 444). The knowledge and attitude toward the elderly had slightly positive correlation(r=0.155). Dental hygienists are being required gradually as the primary staff for the elderly people's dental care in the aging society. A continuous education is needed so that dental hygienists can have positive sight in understanding, knowledge, and attitude. And, the development in a mouth care program for the elderly in line with it is considered to be necessary.

본 연구에서는 국내 제조 및 서비스업체를 대상으로 하여 기업의 경영전략과 정보화 전략의 적합성 요인이 기업 특성 요인과 정보기술의 도입성과 간에 조절적인 역할을 하는지에 대하여 검증을 하였다. 과업특성은 정보 제공정도, 시스템 품질, 지각된 효과, 환경특성은 경쟁정도, 외부압력, 환경 불확실성 등으로 설정하여 분석을 하였다. 분석결과 전략의 적합성 요인은 과업특성의 시스템 품질, 지각된 효과, 환경특성에서는 경쟁정도, 외부압력, 환경 불확실성 등의 변수와 도입성과 간에 조절적인 영향을 미치는 것으로 분석되었다. 그러나 전략의 적합성이 과업특성의 정보 제공정도와 도입성과 간에는 조절적인 역할을 하지 않는 것으로 분석되었다. 따라서 기업에서는 새로운 정보기술의 도입과 확산을 위해서는 기업의 경영전략과 정보화 전략이 서로 밀접하게 계획되고 실행되어야 함을 알 수 있었다.

본 연구에서는 실리콘 기판 상에 제작된 3D 결합구조를 가지는 코프레너 선로인 CWP3DCS(coplanar waveguide employing periodic 3D coupling structures) 구조에 대한 특성임피던스와 대역폭특성을 연구하였으며 이를 통해 완전집적형 해양무선통신 반도체 SoC(System on Chip)를 구현하기 위한 수동소자의 개발가능성을 검토하였다. CWP3DCS에 대한 특성임피던스와 대역폭특성을 추출하기 위해서 삽입손실에 대한 측정값을 반영한 measurement-based equation을 유도하였으며, 이 방법의 유효성을 검증하기 위해 전송상수 β와 특성임피던스에 대한 측정값과 measurement-based equation으로부터 추출된 계산값을 비교하였다. 비교 결과에 의하면 특성임피던스와 전송상수 β에 대한 계산값과 측정값의 최대오차는 각각 3.9%와 6.4%의 값을 보여주었다. 본 논문의 연구결과에 의하면, CWP3DCS 구조는 주기적 구조의 길이 LT = 30 ~ 150 ㎛의 범위에서 통과대역이 121 GHz인 광대역 특성을 보여주었으며, 특성임피던스 역시 주파수 의존성이 매우 적은 광대역 특성을 보여주었다. 그리고, 20 ㎛의 선로 폭으로도 20 Ω이하의 낮은 임피던스를 가지는 전송선로의 구현이 가능하였으며, 동일한 임피던스를 가지는 기존 전송선로의 선로 폭 3mm에 비해 선로 폭이 크게 감소하였다. 그리고, 주기적 구조의 길이 LT값을 조정함으로써 원하는 특성임피던스 값을 가지는 구조를 반도체 기판 상에 용이하게 구현할 수 있음을 알 수 있었다. 상기 결과로부터 CWP3DCS 구조는 완전집적형 무선통신 반도체 SoC용 정합 및 수동소자로써 유용하게 사용될 수 있음을 알 수 있었다. 본 논문은 3D 결합구조를 가지는 코프레너 선로인 CWP3DCS의 대역폭에 대한 최초의 연구이다.

Recently the development of GIS and spatial information technology is used to construct very detail forest information. In addition, in order to classify forest characteristic, the geographical characteristic information of forest could be very useful for the forest classification, In this study sampling points were arranged to clarify the difference between the orm area and the land forest area. Also, forest feature pattern could be discriminated by using satellite images and SML. This study result should be constructed to efficiency forest management in especially forest area in Jeju Island

The purpose of this study is to investigate the characteristic of the thermal environment at a living room by the heating system(floor radiation heating, forced convection heating, combined heating, radiation convection heating), and to compares the change of the thermal environment after operating the heating with after the operation stopped based on the floor radiation heating. This study proposes the basic data for the design and the development of the thermal storage structure heating system which not only utilizes fully the characteristic of the comfortable thermal environment but also reduces the preheating period and be able to use the off-peak electricity.
