The present paper investigates the chatter stability of a milling spindle-workpiece system in face milling process. To this end, a new method using frequendy response function is adopted for predicting the chatter vibration. A compliant workpiece is used to make the spindle-workpiece system easily exposed to chatter vibration. The entire experimental procedure, including measurement of frequency response function and cutting coefficients, is demonstrated. The experimental result shows that the chatter stability prediction method using frequendy response function is of great use in face milling process.

A pocket park is valued in securing green space in downtown and improving urban view in the aspect of natural and environmental values, and it signifies a lot as the center of local residents’ community and harmony as well. Since subway exits and surroundings that have high portions in taking up street space due to lack of green space in downtown aren't made full use of, valuable pocket park place. Dangni Pocket Park of subway exits is a park completed with cooperative works and partnership by students, specialists, administrative organizations, businesses and civilian organizations, etc. without support of special budget. The study site was finally chosen to the space between exit No.1 of Dangni subway station, after analyzing the surrounding circumstances, availability and accessibility of the space among the several subway station exits of Saha, Dangni, and Hadan Station in Busan Metropolitan city. For the designing process, The Citizens organization for Million Amenity Park performed the planning and project proceeding, and 19 design drafts were proposed during the class of landscape architecture in Dong-a University. Design review panel members discussed to select the best draft in practical and authentical, and the related experts reviewed and revised to present the final design plan. The construction was conducted was performed under the cooperation between the civil, authorities, and industrial organizations, among which Saha District office managed for the waste treatment and maintenance matters. The graduates of landscape architecture department of Dong-a University and related industrial enterprises supplied landscape materials and related labors, were supported by 20 members of GPM, one of clubs of Dong-a University volunteered durig the most of construction progress, completing the Pocket Park of subway exits through partnership.

Tracheobronchopathia osteochondroplastica (TPO) is a rare benign disease of unknown etiology characterized by multiple cartilaginous or bony submucosal nodules, which project into the tracheobronchial lumen. Although some disorders were reported combined with TPO, these seemed to be considered casual. We report a case of TPO that combined with adenocarcinoma of lung. She was 50-year-old non smoking woman presented with chronic cough with right chest pain. Lung mass on right lower lobe was found on chest x-ray, so lung cancer was suspected. Multiple scattered whitish small elevations from trachea to bronchial trees were found on bronchoscopic exam. We mistook these lesions for metastases from lung cancer and biopsies of these lesions were done. Transbronchial biopsy for right lower lobe mass lesion was also done. But biopsies from trachea and bronchus revealed TPO rather than lung cancer. Transbronchial lung biopsy of right lower lobe mass was diagnosed adenocarcinoma of lung. So TPO combined with adenocarcinoma of lung was diagnosed.

명대 장경악은 기상 현상에 관하여 “오운육기를 토대로 기화를 추측하면 피차의 영허에 대해 십중칠팔은 들어맞는다”고 하였는데, 이를 착안하여 논자는 『황제내경』에 기재된 기상에 관하여 운기의 기후 특징을 한반도 서울을 중심으로 실제 기상관측 자료와 비교 분석하였다. 기상청 자료를 토대로 서울의 평균 풍속·평균 기온·강수량·평균 습도를 운기 이론 가운데 대운과 비교하였다. 또한 과거 1564년에서 1863년까지 한반도의 이상 기후 발생 빈도와 운기성쇠·운기동화·운기순역과 비교하였을 때, 운기동화의 경우와 이상 기후 발생 빈도와 일치하였다. 다만 본 논문의 실제관측 자료와 통계는 한국의 서울을 중심한 분석이기에, 중국과의 어느 정도 오차를 고려하여야 할 것이다. The comparison of climate s character of Yunqi(運氣) with the data of meterological observation were made in the research of climate. 1. The comparison of the average velocity of wind, temperature, rainfall, humidity of Seoul, by late 1954 to 1983, with Yunqi(運氣) was made. Fire-Chi(火氣) and moistme-qi(??氣) were matched with the attribute of Taiyun(大運). Cold-qi(寒氣) was had some relationshlp. Dry-qi(??氣) and Wind-qi(風氣) were not matched. About the relationship of Spirit-of-official-sky(可天之氣) with climate, when the Moisture-soil(??土) was added, they were matched and when the King-fire(君火) was added, they have some relationship. But Wind-tree(風木), Dry-metal(??金), Buble-fire(相火), Cold-water(寒水) was added they were not matched. 2. According to the observation data of rainfall by late 180 years of Seoul; about Taiyun(大運), when the Water-Yun(水運) was greatly exceeded and Fire-Yun(火運) was shorted, in the case of Official-sky(司天), when Wind-Tree(風木) was added, the frequency was highly. So when the Soil-Yun(土運) was greatly exceeded and when Official-sky(司天)was added to the Moisture-soil(??土), the rainfall was not matched. 3. The relationship of the frequency of the abnormal climate occurrences between Yunqi-promotion-weak(運氣盛??)and Yunqi-Hannony(運氣同化) and Yunqi-soft-attaclung(運氣順逆) in the weather of Korean Peninsula was compared by 1564 to 1863. They were not matched except the case of Yunqi-Harmony(運氣同化). 4. There were some cases which were not matched exactly between the climate predicted by the theory and real climate in 1984, the year of Kap-ga(甲子年). But many correspondence between the observation by the office of meteorology and the prediction by the analysis from Yun-qi-sang-hab(運氣相合) theory. 5. Because meterological phenomena of real world and analysis from the hypothesis of Yunqi(運氣) have no relationship with each other, some of Doctor denied Yunqi(運氣) in the way of matching mechanically. But the thought of Doctor who denied Fortune-spirit(運氣) made promotion for the theory of divination by bringing deeper insight. And it was not only the negative side. 6. In the point of geographical difference, the climate of China, the origination Yunqi theory, is different from the Korea's. Thus some observation errors should be considered. From the basis of this thesis, I hope that the deeper advance would be made into the Korean Yunqi theory.

ZnO thin films on si wafer were deposited by on RF magnetron reactive sputter with various RF power, chamber pressure, argon/oxygen gas ratios and substrate temperatures. Crystallinities, surface morphologies, and electrical properties of the films were investigated by XRD, AFM, and electrometer(keithley 617). All films showed a strong preferred orientation along the c-axis on substrate. Surface roughness and resistivity depended on the argon/oxygen gas ratio. The minimum surface roughness of 12Å and maximum resistivity of 108 Ω ㎝ were achieved at Ar/O2=0/100.

The biological surveys were performed at seven sites in the Gangjin bay from February, 1998 to November, 2001. In order to analysis of environmental variation, numbers of heterotrophic bacteria, general fungus and fecal coliforms were enumerated in each sample. The result showed that variation range of heterotrophic bacteria, general fungus, and fecal coliforms were 2.9 x 10^(3)~9.6 x 10^(3) CFU/ml, 17.2~80.1 CFU/ml, and 6.3~682.5 CFU/100ml for four tears(1988~2001), respectively. Density of heterotrophic bacteria and general fungus were gradually decreased for four tours, while fecal coliforms were suddenly increased. Specially, numbers of fecal colifoms were increased the more 100 times in 2001 than that 1998. We think that it was probably caused a little rainfall in February, 2001. There result suggests that ecosystem of Gangjin bay were mainly regulated by 2~3 factors, which were inflow of fresh water, salinity and variation of water temperature.

At the area of Yuhak, Cheonsaeng and Seongam mountains in Kyeongbuk, we studied the vegetation patterns with 75 plots on the base of Braun-Blanquet methods from March to October 2002. For the analysis of community patterns with 75 plots we used interspecies Affinity analysis method, DECORANA and TWINSPAN. The investigated area was divided into 17 communities with 177 species, and 20∼100% of treelayer, 10∼95% of shrublayer and 20∼100% of herblayer. By toe method of affinity analysis, it showed a big community with 86 species, but divided into 6 small groups by ordination and classification methods. Although it appeared as one group by the affinity test, the area divided into two groups by classification method at second level with eigenvalue of 0.320 and 0.430. It shows that the area of Yuhak, Cheonsaeng and Seongam mountains have own properties and in the process of succession.
