  • Compared to traditional fashion design, modern fashion design is used as a means that creates original and multiple types of beauty beyond fixed and standardized concept and form. Overlapping technique is the most suitable means to shed classical, authoritative and conservative form and it enables diverse borrowing and quotation for creation. This study aimed to analyze overlapping techniques that are expressed in art, architecture and fashion to find out its characteristics in the field of fashion. The result of this study is as follows. Based on theories of visual perception and advance research, types of overlapping technique were classified as pile, repetition, penetration and transparency. When comparing overlapping techniques in modern fashion with those of painting and architecture, fashion was distinctive in that it had movement and communicativeness through overlapping of fashion and the human body. Therefore, the overlapping technique has wide application and adaptation and can cause specialty, movability, communicativeness and collectivity, which can arouse psychological inspiration.

  • This paper presents a decentralized controller design for formation flying of multiple satellites based on the overlapping decomposition technique. Each satellite is assumed to avail only the information of its own and in front of itself, which restricts the structure of a controller gain matrix to an overlapped form. The concerned large-scale system is expanded using the overlapping decomposition technique. Design condition is represented in terms of linear matrix inequalities with small-scale systems in a decentralized form, based on the expanded system. The resulting controller is contracted to the original overlapped form so as to close the original system. A numerical simulation shows the effectiveness of the proposed technique.

  • 현재 건설사업 실무에 활용되는 대부분의 공정관리 소프트웨어들은 PDM(Precedence Diagramming Method) 기법을 적용하고 있는데 이는 작업 간 중복표시가 가능하기 때문이다. 그러나 기존 PDM방식의 작업 간 중복관계는 선 후행 작업간 착수 및 종료시점을 연결하는 네 가지 조합으로 표시되는데, 실제 건설 사업에서 선 후행 작업 간 중복관계는 작업의 중간시점 어디에서라도 상호 연관관계를 가질 수 있지만 PDM기법은 이를 효율적으로 표현하지 못한다. 따라서 본 연구에서는 작업 간 중복관계를 표시할 때, 작업의 착수와 종료시점에만 국한되지 않고, 작업의 중간 어느 시점에서도 작업 간 상호관계를 연계시킬 수 있을 뿐만 아니라 복수의 중복관계도 표시 할 수 있는 새로운 공정관리 기법인 BDM(Beeline Diagramming Method)기법으로 기존 PDM기법의 네 가지 표현방법을 전환시키는 방법을 제안한다. 이를 통해 기존의 PDM기법으로 작성된 CPM공정계획이 BDM기법의 CPM(Critical Path Method) 공정계획으로 전환이 가능하게 되며, BDM기법의 장점을 활용하여 공정관리의 효율성을 향상시키며 궁극적으로 공정관리의 발전에 기여하고자 한다.

  • Since the late 1980s, the schedule technique applied to the construction industry around the world has rapidly changed from the traditional ADM (Arrow Diagramming Method) to the PDM (Precedence Diagramming Method) technique. The main reason for this change is to overcome the limits and inconveniences of the traditional ADM technique. The time-cost trade-off is one of the core scheduling techniques to establish the best optimized combination plan in terms of a relationship between the cost and schedule. However, most of the schedule-related textbooks and research papers have discussed and proposed applications of a time-cost trade-off technique based only on the Finish to Start relationship. Therefore, there are almost no consideration and discussion of problems or restrictions that emerge when the time-cost trade-off technique is applied to the PDM network that has overlapping relationships. This paper proposes the lead-time adjustment method as a methodology for overcoming some restrictions that are encountered when the time-cost trade-off technique is applied to the overlapping relationships of the PDM network.

  • In this paper, we propose a new accurate and robust image mosaic technique of the mural underdrawing taken from the infra-red camera, which is based on multiple image registration and adaptive blending technique. The image mosaicing methods which have been developed so far have the following deficits. It is hard to generate a high resolution image when there are regions that do not have features or intensity gradients, and there is a trade-off in overlapping region site in view of registration and blending. We consider these issues as follows. First, in order to mosaic Images with neither noticeable features nor intensity gradients, we use a Projected supplementary pattern and pseudo color image for features in the image Pieces which are registered. Second, we search the overlapping region size with minimum blending error between two adjacent images and then apply blending technique to minimum error overlapping region. Finally, we could find our proposed method is more effective and efficient for image mosaicing than conventional mosaic techniques and also is more adequate for the application of infra-red mural underdrawing mosaicing. Experimental results show the accuracy and robustness of the algorithm.

  • The purpose of the present study was to investigate associations between periapical and bitewing techniques by assessing the crestal alveolar bone. This article also reports the ability of these two techniques to correctly detect evidence of interproximal dental caries, and comparison between the interproximal overlapping of teeth. Bitewing and periapical radiographs were used from posterior quardants of 243 dental students in Seoul National University. The distance from cemento-enamel junction to the alveolar crest (CEJ-AC) was measured for each proximal surface from the distal of cuspid to the distal of second molar. Data were arranged according to the proximal surface examined, and bitewing and periapical measurements were compared using paired tests. The obtained results were as follows: 1. In maxilla, a significant t ratio with a P value of 0.05 or less reached for 100% and in mandible, reached for 94%. 2. The anatomic limitations imposed on periapical radiographic technique, most often result in somewhat foreshortened radiographic images. This situation would tend to be accentuated by the anatomical restrictions of the hard palate. 3. Consequently, since the significant differences frequently exist between measurements obtained from bitewing and periapical techniques, it is important to define which technique is used. 4. The number of the interproximal overlapping was the largest medial side of the maxillary second molar, while the smallest at the distal side of the mandibular second premolar. And the overall number of the interproximal overlapping was more (538) in the periapical technique than in the bitewing technique (372). 5. The interproximal dental carious lesions were detected more (74) on the bitewing films than on the periapical ones (23). The fact was resulted from the small number of interproximal overlapping and relative easi- ness of obtaining horizontal angulation in taking the bitewing radiographs.

  • 본 논문에서는 두 노드가 하나의 중계 노드를 통하여 서로 데이터를 주고 받는 양방향 중계 채널에서 물리계층 네트워크 코딩을 적용하여 데이터 전송률을 향상시키는 기술을 고려한다. 특히, 두 노드가 데이터를 중계 노드로 전송할 때 패킷의 길이가 서로 다른 통신 상황을 고려한다. 시뮬레이션 결과를 통하여 두 노드가 전송한 길이가 다른 패킷들의 겹치는 정도에 따라 두 패킷 중 길이가 긴 패킷의 비트오류확률(bit error rate, BER)이 변화하는 것을 확인하였다. 길이가 짧은 패킷의 경우 전체 패킷이 항상 겹치므로 패킷의 겹침 정도와 상관없이 BER이 일정하고 길이가 긴 패킷의 경우 겹침정도가 작을수록 BER 성능이 좋아진다. 네트워크 코드가 적용된 패킷의 BER은 두 패킷 중 높은 BER을 갖는 패킷의 성능에 의존하므로 향상된 BER을 달성하기 위하여 새로운 방식의 전송방식이 필요함을 알 수 있다.

  • Objective : To evaluate the safety and efficacy of an overlapped stenting-assisted coiling technique in treating vertebral artery dissecting aneurysm (VADA) via Low-profile Visualized Intraluminal Support (LVIS) stent-within-Neuroform EZ stent. Methods : From January 2017 to June 2019, 18 consecutive patients with VADAs (ruptured : unruptured=5 : 13) were treated with the overlapping stents assisted-coiling technique in our center. The overlapping manner was a Neuroform EZ stent being deployed first, followed by LVIS stents placement using the 'shelf' technique. The patients' clinical characteristics, technical feasibility and safety, and immediate and follow-up angiographic results were retrospectively reviewed. Results : Seventeen (94.4%) procedures were technically successful with an exact deployment of the stents and patent parent or perforator arteries. The immediate angiographies after procedure confirmed Raymond class I, II, and III occlusion of VADAs were in 12 (66.7%), two (11.1%), and four cases (22.2%), respectively. Post-procedural complications developed in one patient (5.6%) with minor brainstem infarctions, which resulted from an in-stent thrombosis during the procedure. Angiographic follow-up at 5.7 months (range 3 to 9 months) demonstrated Raymond class I and II occlusion were in all cases (100%). The modified Rankin Scale scores at 21.3 months (range 15 to 42 months) 0-2 in 17 cases (94.4%) and three in one case (5.6%). Conclusion : Overlapping stents via LVIS stent-within-Neuroform EZ stent combined with coiling is safe and effective for patients with VADA in the midterm results.

  • 두 개의 정규 모집단의 평균이 같은가를 검증할 때 두 개의 신뢰구간이 겹치는 지를 시각적으로 판단하여 결정하는 방법은 매우 직관적이면서도 사용하기 쉽다. 그러나 신뢰구간이 겹칠 때도 두 집단의 평균은 통계적으로 유의하게 다를 수 있으므로 가설검증 결과와 다를 수 있다. 평균 차에 대한 신뢰구간을 각 평균의 신뢰구간으로 변환한 후에 두 신뢰구간이 겹치는지 여부를 시각적으로 판단하여 가설검증을 할 수 있는 방법을 제안한다. 또한 이 방법은 분산이 같은 k개의 정규 모집단의 평균을 비교할 경우에도 사용할 수 있음을 보인다.
