최근 인구감소와 도시 쇠퇴로 인해 도시 자체의 질적 변화를 유도하고 차별화 된 발전모델을 만드는 방안이 매우 중요해지고 있다. 지역문화는 고유성과 다양성을 바탕으로 창의적인 활용에 따라 다양한 콘텐츠의 확장과 파급효과를 가져온다. 본 연구에서는 문화적 활기가 넘치고, 지속가능한 로컬 생태계를 조성하는 차원에서의 문화콘텐츠 개발과 장소만들기로서 '마을스테이(마을호텔)'라는 새로운 로컬콘텐츠의 접근 방식을 살펴 보고자 한다. 개별 콘텐츠의 독창성과 창의성이 지역의 매력을 돋보이게 할 수 있겠으나, 일부 소도시의 사례를 통해 살펴본 결과, 콘텐츠적 요소(장소, 이야기, 사람)를 마을스테이라는 면(area) 단위 콘텐츠로 구체화함으로써 밀도 있게 제시하여 가시성을 높이고, 지역 연결성을 드러낸 다양한 콘텐츠로 확장시키는 것을 확인할 수 있었다. 핵심 주체인 로컬크리에이터는 지역성을 이해하고 능동적 활동을 유도하며, 경제적 가치뿐만 아니라 지역사회의 연대를 도모한 지속가능한 발전을 추구한다.

Overlay multicast is proposed as an alternative approach for providing muticast services. A logical infrastructure is built to form an overlay network on top of the physical layer. In this paper, we propose an efficient overlay multicast in wireless ad hoc networks. The overlay multicast tree adapts to the changes in underlying networks. The multicast tree adjusted according to the local member information.

In Korea, global warming caused by the climate changes impacted on weather system with increase in frequency and intensity of precipitation, and the rainfall pattern changes significantly by regional groups. Furthermore, it is expected that the regional and annual fluctuation ranges of the rainfall in the future would be more severe. Nowadays, agricultural drainage system designed by the existing standard of 20-year return period and 2 days of fixation time cannot deal with the increment rainfall such as localized heavy rain and local torrential rainfalls. Therefore, it is required to reinforce the standard of the drainage system in order to reduce the agricultural flood damage brought by unusual weather. In addition, it is needed to improve the standard of agricultural drainage design in order to cultivate farm products in paddy fields as facility vegetable cultivation and up-land field crop have been damaged by the moisture injury and flooding. In order to prepare for the changes of rainfall pattern due to climate changes and improve the agricultural drainage design standards by the increase of cultivating farm products, the purpose of this study is to examine the impact of climate changes, the changes of relative design standard, and the analytic situation of agricultural flood damages, to consider the drainage design standard revision, and finally to prepare for enhanced agricultural drainage design standards.

This study was undertaken to investigate soft tissue profile changes by orthodontic treatment in female patients. Traditional cephalometric appraisal yields data of dubious scientific value, the soft tissue profile forms were evaluated by finite element method. The subject was divided into three groups according to Angle's classification and each group was composed of 25 female patients averaged aged 12-14 years at the start of treatment. The changes in soft tissue form were evaluated by computing the degree of distortion in each triangle after treatment compared with the triangle before treatment. The conclusions were as follows; 1. The soft tissue profile forms were evaluated by finite element method and independent evaluation of each element by local changes was possible. 2. Maximum and minimum principal strains showed marked variability depending on the particular finite element and each group and Class II, III sample was greater than Class I sample. 3. Soft tissue size changes as a result of orthodontic treatment was not related to those of shape. 4. Soft tissue changes by orthodontic treatment were variable in individual patient, and were not related to Angle's classification.

In visual object tracking, Correlation Filter-based Tracking (CFT) systems have arouse recently to be the most accurate and efficient methods. The CFT's circularly shifts the larger search window to find most likely position of the target. The need of larger search window to cover both background and object make an algorithm sensitive to the background and the target occlusions. Further, the use of fixed-sized windows for training makes them incapable to handle scale variations during tracking. To address these problems, we propose two layer target representation in which both global and local appearances of the target is considered. Multiple local patches in the local layer provide robustness to the background changes and the target occlusion. The target representation is enhanced by employing additional reversed RGB channels to prevent the loss of black objects in background during tracking. The final target position is obtained by the adaptive weighted average of confidence maps from global and local layers. Furthermore, the target scale variation in tracking is handled by the statistical model, which is governed by adaptive constraints to ensure reliability and accuracy in scale estimation. The proposed structural enhancement is tested on VTBv1.0 benchmark for its accuracy and robustness.

As a series of safety studies of DA-3030, a new rhO-CSF, its local irritancy was examined in the rabbits after the following treatment; application into the conjunctival sac of the eye(single), subcutaneous injection(single), intramuscular injection(single), and intravenous injection(8-day repeated). In addition, paravenous irritation of DA-3030 was investigated in mice. The results obtained were as follows. 1. In the result of ocular irritation test, 0.03% solution of DA-3030 could be considered as a non-irritating material. 2. The local irritation of DA-3030 by an injection of 0.5mι of its solution subcutaneously or intramuscularly was negligible and not so much different from that of saline. 3. In the vascular irritancy test, macro- and microscopic observations revealed that the irritating activity of DA-3030 in blood vessels was not different from that of saline when they were injected once a day into vein retroauricularis of rabbits for 8 days.4. The paravenous administration of DA-3030 did not induce any abnormal changes at injection sites except mild swelling in 1 mouse at 3 hours after injection which was thought to be due to slow absorption. The above-mentioned results suggest that DA-3030 has no irritating activity when injected through intravenous or subcutaneous route for clinical practice as 0.03% solution.

본 논문은 기술적인 진보보다는 개념적 변화에 초점을 맞추어 근거리통신망의 진화 방향에 대하여 살펴본다. 현재까지 많이 사용되는 주요한 근거리통신망 기술을 토폴로지, 채널의 타이밍구조, 매체접근제어 항목으로 분류하고 최근 근거리통신망에서 나타난 진전된 기술 및 새로운 개념들을 살핀다. 근거리통신망의 진화에서 가장 영향을 미친 근본적인 요소는 집중형 백본 개념으로 보인다. 종래의 LAN의 개념과는 근본적으로는 다른 ATM 기술이 LAN에 적용되고 있으며, 전통적인 근거리통신망이 ATM과 경쟁하기 위해서는 QOS의 지원이 가능하도록 발전해야 될 것이다.

Factors for promoting the resident participation in mountain villages are suggested to introduce the activity-oriented program of green tourism using a multinomial logit model(MNLM). Direct surveying, using a structured questionnaire was performed on local residents in the different types of rural tourism villages such as mountain villages, agricultural themed villages, and the mixed types of villages. The MNLM revealed that participation intention in the program was significantly higher for males, those with lower education, and residents in mountain villages. The participation intention of the program had a negative relationship with the increase of expected problems not from the program itself, but from the results of the program such as income distribution and nature destruction. Participation intention also increased with the indirect effects of an investment by the Village Development Project, such as local cooperativeness, public mind, etc. It was suggested that to introduce the activity-oriented program in mountain villages, negative effects from the results had to be minimized, and positive effects from the indirect changes between local residents had to be maximized through better communication and policy endeavors.
