  • Background Breast reconstruction refers to the rebuilding of a woman's breast using autologous tissue or prosthetic material to form a natural-looking breast. It is increasingly offered to women undergoing mastectomy for breast cancer. However, there is no systematic analysis available for the expanding area of research on breast reconstruction. Methods A bibliometric method was used to obtain a view of the scientific production about breast reconstruction by data extracted from the Institute for Scientific Information (ISI). Specific parameters were retrieved from the ISI. Articles about breast reconstruction were analyzed to obtain a view of the topic's structure, history, and document relationships using HistCite software. Trends in the most influential publications and authors were analyzed. Results The number of articles was constantly increasing. Most highly cited articles described the methods of flap construction in the surgery. Other highly cited articles discussed the psychological or emotional aspects of breast reconstruction, skin sparing mastectomy, and breast reconstruction in the irradiated breast. Conclusions This was the first breast reconstruction scientometric analysis, representing the characteristics of papers and the trends of scientific production. A constant increase in the number of breast reconstruction papers and also the increasing number of citations shows that there is an increasing interest in this area of medical science. It seems that most of the research in this field is focused on the technical aspects of surgery.

  • The data-flow paradigm has been employed in various application areas. It is particularly useful where large data-streams must be processed, for example in video and audio processing, or for scientific visualization. A video-based 3D reconstruction system should process multiple synchronized video streams. The system exhibits many properties that can be targeted using a data-flow approach that is naturally divided into a sequence of processing tasks. In this paper we introduce our concept to apply the data-flow approach to a multi-video 3D reconstruction system.

  • Temporomandibular disorders typically present findings of limited or asymmetric patterns of jaw opening and joint sounds usually described as clicking, popping, grating, or crepitus. Recently, patients with temporomandibular disorders have received an increasingly aggressive treatment with a greater emphasis on surgical and dental reconstruction. Scientific studies have not clearly identified the specific causes of the temporomandibular disorders and therefore some of the treatments are empiric, without a firm scientific foundation. We carried out a study on the patients of pain clinic OPD and concluded that the causes of the temporomandibular joint(TMJ) pain are the prolonged contraction of the muscles of mastication, especially the masseter muscle. Therefore, the spasmolytic treatment of masseter muscle would be a better treatment for TMJ syndrome rather than the surgical and dental reconstruction.

  • The reconstruction of archaeological fragments in 3D geometry is an important problem in pattern recognition and computer vision. Therefore, we implement an algorithm with the help of a 3D model to perform reconstruction from the real datasets using the slope features. This approach avoids the problem of gaps created through the loss of parts of the artifacts. Therefore, the aim of this study is to assemble the object without previous knowledge about the form of the original object. We utilize the edges of the fragments as an important feature in reconstructing the objects and apply multiple procedures to extract the 3D edge points. In order to assign the positions of the unknown parts that are supposed to match, the contour must be divided into four parts. Furthermore, to classify the fragments under reconstruction, we apply a backpropagation neural network. We test the algorithm on several models of ceramic fragments. It achieves highly accurate results in reconstructing the objects into their original forms, in spite of absent pieces.

  • The paper is the principle of a curriculum, a recent method of teaching-learning in pedagogy, and intended for the exploration of the meaning of which reconstructs curriculum by narrative through practical exploration and narrative being discussed as the form of exploration. To date, Korean education showed an inclination of the traditional paradigm centered thinking and has emphasized the results by the method of scientific investigation. Even a curriculum reconstruction demonstrates documents that produce results without actually demonstrating the actual school setting. With communication one another is becoming increasingly important, we need the conversion of cognitive thinking that can express dilemma, contradictions, and complexities of the human world of which unexplainable by traditional paradigm mindset. Ultimately, the exploration of the direction that reflects a series of verbal, symbolic, and spiritual activities, which analyze lives of students, understanding and composing the meaning by using narrative, which talks about the experience of the human world in curriculums, is an important task for us.

  • The side collision reconstruction algorithm is developed using three dimensional car crash analysis. Medium size passenger car is modeled for finite element analysis. Total 24 side collision configurations, four different speed and six different angle, are set up for making side collision database. Deformation index and degree index are built up for each collision case. Deformation index is a kind of deformation estimate averaging displacement of side door of crashed car from finite element analysis result. Angle index is constructed measuring deformed angle of crashing car. There are two kinds of angle index, one is measured at driver's side and the other is measured at passenger's side. Also a collision analysis information in side of cars is used for giving a basis for scientific and practical reason in a reconstruction of the car accident. The analysis program, LS-DYNA3D is utilized for finite element analysis program for a collision analysis. Those database are used for side collision reconstruction. Side collision reconstruction algorithm is developed, and applied to find the collision conditions before the accident occurs. Three example collision cases are tried to check the effectiveness of the algorithm. Deformation index and angle index is extracted for the case from the analysis result. Deformation index is compared to the established database, and estimated collision speed and angle are introduced by interpolation function. Angle index is used to select a specific collision condition from the several available conditions. The collision condition found by reconstruction algorithm shows good match with original condition within 10% error for speed and angle. As a result, the calculation from the reconstruction of the situation is reproducing the situation well. The performance in this study can be used in many ways for practical field using deformation index and degree index. Other different collision situations may be set up for extending the scope of this study in the future.

  • The purpose of this study is to explains consumers' medical discourse embedded in the consumption of oriental medicine and health functional foods. Despite the fact that both of oriental medicine and western medicine is legally accepted, people tend to recognize that accurate diagnosis is possible only in the latter. As the discourse that oriental medicine, compared with western medicine, has an auxiliary position is widely spreaded, the rivalry between herbal medicine and health functional foods come to be formed. And it led to a close correlation between the decrease of herbal medicine consumption and the growth of health supplement market. Herbal medicine is compared to red ginseng, one of the representative health supplement. Negative notion such as using an Asian herb from China and side effect of hepatotoxicity influences herbal medicine consumption. This study argues two conclusion. First, the correlation between the consumption of herbal medicine and that of health functional foods results from the discourse of scientific reconstruction, standardization, and commercialization all of which come from globalization discourse. Second, medical discourse embedded in these commodity, in the end, has impact on agricultural production.

  • This research was a technical case study for the authentic restoration of the seven-storied Simgoksa stone pagoda after disassembly and reconstruction using three-dimensional image analysis. During disassembly and reconstruction, the pagoda's properties were analyzed in terms of the overall modification and displacement of the pagoda. Distortion was minimized by ensuring structural stability during the reconstruction process. Also, the original site of the pagoda was examined in order to utilize it fully during rebuilding. Before reconstruction of the pagoda, moss and lichen on the stone surfaces were removed by scientific surface cleaning. The foundation of the pagoda was reinforced with rammed earth than was similar to the original foundation using a mixture of soil and quicklime. The results are expected to provide valuable data for the reconstruction of other stone pagodas.
