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.

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.

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.

Background: To investigate clinical features and risk factors of stroke patients who lived in Korean rural area, we analysis Wonkwang Stroke Registry and compared with other studies. Methods: We filled out Stroke Registry in the consecutive patients with acute ischemic stroke from march 1997 to February 1999. We analyzed demographic data, risk factors and subtypes of stroke. All patients were divied into 3 groups according to their age. Stroke subtype was classified into large artery atherosclerosis(LAA),small vessel occlusion(SVO), cardioembolism(CE), stroke of other determined etiology(SOE), and stroke of undetermined etiology(SUE) by TOAST(Trial of Org 10172 in Actue Stroke Treatment). Results: Five hundred nine patients were included in Wonkwang Stroke Registry from march 1997 to February 1999. Mean age was 65.47±0.48 years old. The ratio of males to females was 1 : 0.78. SVO was the most frequent subtype(49%) of ischemic stroke, and then followed by LAA(27.5%), CE(7%), SOE(8.1%), and SUE(8.4%). The internal carotid artery(ICA) territory was involved in 59.3% patients. Vertebrobasilar artery territory involvement was noted in 37.5%, and 3.2% of patients showed multiple artery territory involvement. All patients had risk factor of ischemic stroke except for 14 patients. Mean number of risk factors was 1.7/patient. Hypertension(62.1%) was the most frequent risk factor, and follwed by smoking(26.3%), diabetes mellitus(25.9%), and hyperlipidemia(25.55%). Conclusions: These results showed that the proportion of ischemic stroke subtype was not concordant with other studies. It may be caused by different mode of living and ethnic difference. This study may afford further information on the characteristics of Korean rural area stroke.

The dielectric and piezoelectric properties of the xPb(Al0.5Nb0.5)O3-(1-x)Pb(Zr0.52Ti0.48)O3 [PAN-PZT] thin films by pulsed laser deposition (PLD) were investigated as a function of x. The effect of texture on dielectric and piezoelectric properties of the 0.05PAN-0.95PZT thin films having the highest piezoelectric coefficient(d33) was studied more precisely. For all compositions in xPAN-(1-x)PZT thin films, the well-developed perovskite phase with (111) preferred orientation was obtained at the deposition temperature 500℃, and annealing temperature 650℃. With increasing PAN content, remnant polarization and coercive field decreased. The dielectric constant increased with an increase of PAN content until it reached 1450 at x=0.05, and then decreases for higher PAN content. The maximum points of dielectric constant coincides with the maximum points of the piezoelectric constant d33.

In The general enhancement and the wide diffusion of technologies in manufacturing products has made a great change in evaluating distintiveness of a product from a functional point of view to a communicational one. Teenagers consumers are ready to play more for the mental value of a product than for its practical value these days. It is a time of communication between consumers and products. Most of the marketing tools are concentrated on how to draw consumers' attention, how to start their communication with products, how to prolong their communication and how to induce their next communication. Of late, characters started to be noted as one of the most effective media to enhance the quality of communication between products and Teenagers. Original features of characters such as eye-catching power, story-telling expressions, incitation of imagination, etc. are regarded as key elements to get the communication started. In the Krean market as well as in the global market, character merchandising has become common in promoting teenagers' products.

The typical dimensions of microwave filters are similar to the wavelength at their operating frequency processing a barrier to overall system miniaturization. By using the piezoelectric effect to generate acoustic modes the velocities and thus the wavelengths are reduced by about four orders of magnitude. Thin film bulk acoustic resonators (FBAR) devices exploit this effect and with dimensions of hundreds of microns offer a compact and attractive alternative. So, two-step modeling process was used for optimizing FBAR resonator and filter performance. A physical simulator based on the Mason model was used to determine the resonator. Optimization for FBAR filters has been performed using the serenade simulation program.

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.
