Purpose: We wanted to evaluate the clinical and radiological outcomes and the prognosis of various surgical treatments for the distal clavicle fracture with an acromioclavicular joint injury. Materials and Methods: A retrospective study of 21 patients with a minimum of 12 months follow up was done. We classified acromioclavicular (AC) injury into type I (only intra-articular fracture (IAF), 5 cases), type II (IAF with widening of the AC joint > 7 mm, 9 cases) and type III (IAF with AC joint superior subluxation > 50%, 7 cases). The distal clavicle fractures were fixed using plate (9 cases), mini screws (1 case), K wire and tension band wiring (10 cases) and transarticular pinning (1 case). Acromioclavicular or coracoacromial ligament reconstruction was not done in all the cases. Results: In 20 of 21 cases, bone union was achieved at an average of 8.4 weeks. Traumatic arthritis (5 cases), AC joint widening (4 cases) and AC joint subluxation (2 cases) were noted at the last follow up. The average UCLA score was 32.6 in the type I AC joint injuries, 34 in type II and 34.1 in type III. There was no relationship between the clinical outcomes and the preoperative AC joint injury pattern, postoperative traumatic arthritis, AC joint widening or AC joint subluxation (p>0.05). Conclusion: Satisfactory results were achieved by acute reduction and firm fixation of the distal clavicle fracture with AC joint injury. There was no relationship between the pattern of AC joint injury, the residual radiologic findings and the functional outcome.

Purpose: We wanted to evaluate the result of percutaneous, mini-open reduction for the treatment of Mason II or III radial head and neck fractures. Materials and Methods: 13 patients (8 male, 5 female) with Mason II or III radial head and neck fractures were treated by 1 cm percutaneous mini-open reduction under fluoroscopy. The average age of our subjects was 29 years. Follow up duration was 18 months. Results: Union was noted in all cases. Mean radial neck angulation was decreased from 33.2 degrees to 7.8 degrees. The mean change in angulation between the immediate post-operative and last follow-up was 0.7 degrees. The mean range of motion at the elbow joint was at last follow up, 133.1 degrees in flexion, 7.3 degrees in extension, 80 degrees in pronation and 84.3 degrees in supination. Postoperatively, mean Mayo Elbow Performance Index, American Shoulder and Elbow Surgeons elbow score, and Disabilities of the Arm, Shoulder and Hand score were 96.2, 97 and 1.2. Temporary posterior interosseous nerve palsy (1 case) and minimal cubitus valgus deformity (1 case) were noted. Conclusion: Selected Mason II or III radial head and neck fractures can be treated satisfactorily with percutaneous mini-open reduction.

Freight flow data in Korea has been collected for a variety of purposes by various organizations. However, since the representation and format of the data varies, it has not been substantially used for freight analyses and furthermore for freight policies. In order to increase the applicability of those data sets, it is required to bring them in a table and compare for finding the differences. Then, it is shown that the raw data can be aggregated by a particular criterion such as mode, origin and destination, and type commodity. This study aims to examine the freight data issue in terms of three different points of view. First, we investigated various freight volume data sets which are released by several organizations. Second, we tried to develop formulations for freight volume data. Third, we discussed how to apply the formulations to network models in which particular OR (Operations Research) techniques are used. The results emphasized that some data might be useless for modeling once they are aggregated. As a result of examining the freight volume data, this study found that 14 organizations share their data sets at various aggregation levels. This study is not an ordinary research article, which normally includes data analysis, because it seems to be impossible to conduct extensive case studies. The reason is that the data dealt in this study are diverse. Nevertheless, this study might guide the research direction in the freight transport research society in terms of data issue. Especially, it can be concluded that this study is a timely research because the governmemt has emphasized the importance of sharing data to public throughout 'government 3.0' for research purpose.

This study has been historically reviewed the clothing and textiles education through references. The clothing and textiles education had been informally offered as a part of household skill, skill of daily life and home skill before the law of school education was established. Therefore, we have reviewed the changes in the clothing and textiles education by separating the prior period between the end of the old Korea and the liberation in 1945, from the later period from the liberation up to now. And also contents of clothing and textiles education between before and after the revision of the 7th curriculum were compared and analyzed. The clothing and textiles education had put emphasis on sewing, handicraft and household during the prior period from the end of the old Korea to the liberation, but after liberation, it became involved in Home Economics Education. The number of classes and the contents of clothing and textiles education had been increased and deepened from the 1st term to the 5th term of curriculum. In particular, the 4th and 5th term of curriculum became a turning point where home life section was intensified. Even though the number of classes was reduced during the 6th term of curriculum, with increase in target school grades for this education, and Home Economics in the middle school remained an independent subject matter. However, during the 7th term of curriculum, Technology-Home Economics Education in the middle school courses led to losing independent subject name and shrinking its contents. Through the revision in the 7th curriculum, the clothing and textiles education achieved great improvement and progress by gaining balance in distribution of contents among school grades and balance between theory and practice. However it still remains as an issue to be more studied and resolved how well the contents are matched with the interests and attention of students. We need to consider and reflect request of students under learner-centered curriculum. Considering enormous changes in the environment surrounding the clothing and textiles education, it is crystal clear that the gap between existing contents of education and teaching methods and our real life will be widened. Because students' perceptions of value have been diversified, it is our task to develop better contents and learning system in order to help students have interests, attention and desire in clothing and textiles life in line with social needs for desirable clothing and textiles education.

Koguryo's tomb mural paintings in North Korea are our precious cultural heritage which have been designated as UNESCO World Heritage property receiving high praise in the following criterion, i) exceptional creativeness of human being, ii) representative value showing the stage of development in construction history of East-Asia, iii) aesthetic superiority iv) uniqueness of building construction including tombs' ceiling. Mural paintings have been found from almost 100 tombs of the Koguryo dynasty out of 130 which are scattered across Huanren County, Lianoning Province, Ji'an, Jilin Province in China and Pyongyang in North Korea. Especially, most of them are gathered in Pyongyang from 4th and 5th century. Peculiarly, some of them have been constructed before King Jangsu's transfer of the capital to Pyongyang(AD 427). It can be regarded that Pyongyang territory had been under control of Koguryo and to become a new capital in the near future. And dense emergence of such tombs since the capital transfer from Gungnae City to Pyongyang during the reign of Jangsu is linked closely to the construction of tombs for rulers under strengthen royal authority of Jangsu and centralized system of authoritarian rule. Tomb mural paintings describe the owner's figure pictorially based on the truth just as in his living years. General lifestyles of ruling powers and sovereigns can be seen from the wall paintings portraying several buildings with various styles, figures, manners of living, which are considered that the tomb owner had led politically and sociologically in his life. In spite of not enough proofs to approve figure of architectures or "Gong-Po" in wall paintings on the tombs as those of Koguryo, it is persuasive with consideration for painting and decoration inside the tomb like wooden building in real life for the purpose of reenacting and continuing the tomb owner's luxurious life after death. "Du-Gong-Po-Zak" had appeared in company with Koguryo tomb murals and it can be found in most of the murals. And the emergence of substantial "Gong-Po-Do" can be counted more than a century ahead of the figure in murals. It could be a reasonable assumption as regards Koguryo tomb murals time of appearance match up with production period of Gahyungmyunggi(家形明器) and Hwasangseok(畵像石) Hwasangjeon(畵像塼) Design in the Mural Painting of the East-Han(東漢) Ancient Tombs in China. On this study, architectural "Gong-Po"s described in Koguryo tomb murals are categorized largely in "Bi(non)-Po-Zak-kye", "Jun(semi)-Po-Zak-kye", and "Po-Zak-kye" based on presence of "Ju-Du", "Cheom-Cha", and "Cheom-Cha-Sal-Mi" with developmental aspect, and, "Po-zak" is subdivided as "Bi(non)-Cheul-Mok" and "Cheul-Mok" types.

The purpose of this study was to define the 'caligraphy as a modern concept of art. For this purpose, it was necessary to exclude the elements betraying 'the caligraphy as a pure art' in reference to 'autonomy' as an indicator of modernity in order to reflect on the current topology of the caligraphy in our age. Checking the current conditions facing the caligraphy from the pre-modern, modern and post-modern perspectives will clarify the current topology of the caligraphy and further exploring 'the caligraphy as a post-modern art concept. To this end, this study defines the caligraphy 'as a pure formative art' and thereby discusses it in terms of nature and form. In terms of nature, the caligraphy should be subsumed into a spacial art, but it has a nature of a temporal art created and appreciated over time. Hence, among the spacial arts, the painting is most similar to the caligraphy, while among the temporal arts, the caligraphy is most similar to such rhythmic (of high mobility) or performing arts as music and dance. Merely, the painting does not reveal the flow of time on the canvas, while music and dance leave no residual in terms of audibility and visuality. All in all, the caligraphy is sort of 'temporal-spacial art' like dance in that the visible letters express the artist's sense of life on the plane over time like music. In terms of form, this study compares the caligraphy with engraving, wood print and character design to define the caligraphy as a pure art concept. The caligraphy as a modern art concept, namely, the autonomy of the caligraphy is associated with legibility and meaning in addition to the question whether it is an applied or a pure art. The legibility and meaning of the characters are not only the essential elements of the caligraphy but also are the factors limiting its autonomy, which must be a paradox. All in all, the legibility and meaning of the characters must be the key criteria for determining the caligraphy as a practical art or literary art or as a pure figurative art. In this context, this study discusses the caligraphy as a pure art by comparing it with the spatial art 'painting' and the temporal art 'music.' It might be impossible to define the caligraphy or a genre of art as an autonomous art of self-perfection and categorical identity. Moreover, any attempt to define the caligraphy would fail to interpret the caligraphy appropriately. Merely, we are obliged to position the caligraphy in the process of localizing 'their modernity' and thereby, discuss how to respond to their scheme.

The establishment of the Bronze Age is one of the most important achievements suggested by Korean archaeology shortly after liberation. There is no doubt that Moo-Byung Yoon is the representative figure, who refuted the ambiguous Eneolithic age (金石倂用期) created by Japanese scholars and settled the concept of the Bronze Age. In this article, the author takes a new look at Yoon's institutional role in studying the Bronze Age in Korea. Until now, Yoon's representative achievement has been his typology of the Slender dagger of the Korean Peninsula. However, it is not less important that Yoon also established the Bronze Age concept with the excavation of a dolmen and a Bronze Age subterranean dwelling in Oksok-ni, Paju during the 1960s. Of course, it was not a personal assignment for Yoon. He was aided by Prof. Kim Won-Yong's work, who had introduced newly excavated materials from North Korea and China; these materials gave some insight for establishing the Bronze Age concepts in the 1960 and 1970s. Kim's suggestion about the possibility of a Korean Bronze Age led to Yoon's refined typological study on Korea's bronze wares. However, Yoon's excessive schematic classification of artifacts and reliance on the Japanese chronology became an obstacle for making the Korean Bronze Age isolated from East Asia. As a result, it is regrettable that his research led to the "cultural lag" phenomenon of Bronze Age research. Meanwhile, Japanese archaeology, which had influenced Yoon, also faced a major change. In 2003, the Japanese archaeological community revised the Yayoi culture's beginning around the 1,000 BC. This means a shift in the perception that we should understand Japan's Bronze Age in the context of the East Asian continent. Of course, it is not appropriate to reevaluate or denigrate Yoon's research from the current view. Rather, it is necessary to recognize the limitations of Yoon's time and present a new path to research by combining the archaeological tradition of refining research on the relics he maintained with a new chronological view and a macro view of East Asian archaeology. This is why we should take a new glimpse into Yoon's research.

This study tackles the development of an improved detail of partially restrained CFT square column-to-beam connection and the evaluation of its mechanical behavior under monotonic loading. The connection is designed to strengthen shearing capacity at the bottom of the connection due to the ultimate behavior of PR-CC by its detail of the bottom connection and simplify the fabrication process. The suggested connection is the welded bottom beam flange connection(M-2) and is compared with the existing PR-CC of bolted seat angle connection(M-1). Two specimens were fabricated in actual size and tested under monotonic loading. Based on the test results, the welded bottom beam flange connection exhibited about 85% of the stiffness of steel beam. It was similar to the bolted seat angle connection and behaved as PR-CC. The specimen of the supposed connection type failed at the shear connection of web but was similar to the bolted seat angle connection until the failure. It obtained sufficient stiffness and capacity through the reinforcingsteel and the capacity and deformational ability equivalent to the full-plastic moment through the anchor inside the steel tube at the web connection. So, it can be said that the suggested connection exhibits sufficient ductile behavior.

The meaning of things appeared in the frame vary according to how they look in a shot. Especially, position of frame shows how a form becomes a content in quality. This has a large impact on communication with audiences, reminds them a special feeling or atmosphere toward an object and plays a suggestive role for things that shows up. Thus, this study aimed to investigate how symbolisms appeared in the frame position are shown in the relation among characters' narrative, personality and conflict and understand correlation between frame position and characters accordingly. As an object to be analyzed, this study selected which was played with narratives of couples with different personalities. The results of analysis shows that it is deeply associated with couples' narrative, which means that trauma or the severance of relations between a couple is shown on left side, whereas a positive and future-oriented couple was mainly shown on right side and the rate of being situated in the center turned out to be high according to the power relations of love. Based on the comparison between symbolism appeared according to the frame position and narratives and traumas that various characters have, this study found that frame position is playing an important role in composing characters' personality.

A BIM, which is being applied actively to the construction and civil construction industries, is a technology that can maximize efficiency of various sectors from initial planning and design, construction, and maintenance, to demolition; however, it is in the introductory phase in the field of domestic landscaping. In order to introduce and promote BIM in the field of landscape design, this study developed a prototype of a library and template and analyzed the performance of trial application. For the development of a prototype, annotations and types were analyzed from floor plans of existing small parks, and components of landscape template were deduced. Based on this, play facilities, pergola, and benches were madeintofamily and templates, making automatic design possible. In addition, annotations and tags that are often used in landscape design were made, and a 3D view was materialized through visibility/graphic reassignment. As for tables and quantities, boundary stone table, mounding table, summary sheet of quantities, table of contents, and summary sheet of packaging quantities were grouped and connected with floor plans; regarding landscaping trees, classification criteria and name of trees that are suitable for domestic situations were applied. A landscape template was created to enable the library file format(rfa) that can be mounted on a building with BIM programs. As for problems that arose after the trial application of the prepared template, some CAD files could not be imported; also, while writing tables, the basis of calculation could not be made automatically. Regarding this, it is thought that functions of a BIM program and template need improvement.
