In this study, the adhesion performance of the adhesive between the concrete base and the fiber panel was verified through experiments. Attachment to all three types by applying adhesive to panel and attaching to CRC board surface, method of applying adhesive to CRC board surface by panel, method of applying adhesive on panel and CRC board surface respectively, As a result of the performance test, the adhesive strength of the panel attached to the panel on the CRC board after the application of the adhesive was highest on both the back surface of the panel and the surface of the CRC board.

This paper paid attention to methodology of `community-based tourism' that was one of the Japanese community improvement activation strategies and analyzed this. `community-based tourism' is one of the activated methodology of the community through the sightseeing and aims at the area main constituent-shaped sightseeing promotion as means of the local sustainable growth with increase of the interchange population. Therefore at first I divided the process of the change of the local main constituent type sightseeing promotion into mass tourism, new tourism, and landing sightseeing type as a form of sightseeing and checked it. In the case study, I examined the activated measures as the sightseeing spot through the unique event technique of the Beppu area that fell into long-term economy slump. Specifically, I analyzed the area leadership model example through a natural hot spring, local culture walk, and food culture of onpaku, as the characteristic example of the landing type sightseeing. As a result, next became clear. The inn association society started beppu-hatto community improvement with the goal of regional activation with local sense of impending crisis, and the excavation of local culture resources was performed in the process. It began with a takegawara hot spring preservation campaign and was connected for the establishment of the walking tour through the visiting hot springs. In addition, the result became the step of the regional activation with local image improvement.

마찰과 미끄럼 마멸에서 표면 거칠기의 특성에 대한 효과는 실험적으로 볼-디스크 마멸 시험기를 가지고 연구되어졌다. 실험은 서로 다른 하중, 미끄럼 속도, 그리고 윤활유 점도 조건하에서 산술평균값, skewness, kutosis를 변화시켜 수행되었다. 음의 값을 가지는 더 낮은 skewness 또는 더 높은 kutosis의 표면조도를 가진 같은 상술평균 값에 대하여 더 낮은 마찰을 가지는 경향이 있다. The effect of characteristic of surface roughness on friction and sliding wear was studied experimentally with ball-on-disk type wear tester. The test was conducted with specimens those have varying arithmetic mean value, skewness and durtosis under the condition of different load, sliding speed and lubricant viscosity. The surface of the lower skewness in negative value or the higher kurtosis tends to have low friction for the same arithmetic mean value.
