The Dinosaur tracksite at Jeori, Geumseongmyeon, Euiseonggun, Gyeongsangbukdo, Korea (National Monument No. 373) has been studied in the aspects of location, stratigraphy, sedimentology, fossil occurrence, unique geological records, literature, significance in natural history, preservation, and management. On the basis of these features, the Jeori tracksite has been assessed semiquantitavely. The Jeori tracksite occurs in the Sagok Formation (Albian) of the Euiseong sub-basin, and over 300 footprints forming 12 sauropod trackways, 10 ornithopod trackways, and 1 theropod trackways are preserved in this tracksite. The track-bearing deposits consist of tabular-bedded medium- to fine-grained arkose with mudstone drape, interlaminated fine-grained sandstone to siltstone and mudstone, and shaly mudstone. The dinosaur tracks are preserved in the interlaminated fine-grained sandstone to siltstone and mudstone, and most of them are observed as underprints. The track-bearing deposits are interpreted as sheetflood deposits on the floodplain under a seasonal paleoclimatic condition with alternating of wetting and drying periods. Multiple tension fractures with NE strike were formed in the track-bearing bed, which resulted in that tracks seem to occur in several horizons. The significance in natural history of the tracksite can be summarized as follows: 1) the historical implication of the Jeori tracksite as the firstly designated National Monument of dinosaur fossil sites, 2) the high density of the occurrence of diverse footprints (over 300) within small area (about $1,600m^2$), and 3) the significance of the tension fractures associated with the track-bearing bed as geoeducational records for the understanding the development of fault. In order to share the value of the Jeori tracksite in the aspect of natural history with the community and public, the interpretive panel should be modified to include figures explaining paleoenvironment and tension fault development. In addition it is recommended that a brochure be published briefly explaining the tracksite and to educate the residents about the natural and social significance of the tracksite. For the safety of visitors it would be desirable for the road in front of the tracksite to be moved at least 10 m southward, which could mitigate the shaking of the track bed caused by traffic.

In this study, the landscape characteristics of the sacred Dangsan forests at Singi-ri, Namwon-si were investigated as an agricultural heritage, and the management scheme for revitalization of the village was introduced. FAO established the term of 'GIAHS' (Globally Important Agricultural Heritage Systems) for conservation of each country's farmland, unique agricultural landscape, and cultural diversity. The Ministry of Agriculture, Food and Rural Affairs of Korea evaluates that the Agricultural Heritage is a new means and potential for rural development. Dangsan forest, a traditional village forests of rural Korea is a representative 'agricultural heritage' with a history of more than several hundred years of Dangsan ritual. The Dangsan forests were closely linked with paddy fields. This forest was composed of two Dangsan forests, and one Bibo forest. Especially, the Dangsan forest 2 was established on the mounding with 395m in length and 15m in width. Although, most of Dangsan forests do not have accurate records about forest establishment, this forest has retained a stone monument that illustrated the history of the forest. These aspects of Singi-ri's Dangsan forest indicated clear difference and characteristics compared to other ones. This Dangsan forest has been left alone from the public attention. The Dangsan forest at Singi-ri need to be recognized for their valuable landscape characteristics. By linking the Dangsan forest with 'Jirisan trail', the trail path will lead people to the agricultural heritage at Singi-ri. Enhancing the management scheme will contribute to revitalize the village.

Archival description in archives has an important role in document control and reference service. Archives has made an effort to do archival description. But we have some differences and problems about a theory and practical processes comparing with advanced countries. The serious difference in a theory is that a function classification, maintenance of an original order, arrangement of multi-level description are not reflected in practical process. they are arranged in shelves after they are arranged by registration order in a unit of a volume like an arrangement of book. In addition, there are problems in history of agency change or control of index. So these can cause inconvenience for users. For improving, in this study we introduced the meaning and importance of arrangement of description, the situation and problem of arrangement of description in The National Archives, and a description guideline in other foreign countries. The next is an example for ISAD(G). This paper has chapter 8, the chapter 1 is introduction, the chapter 2 is the meaning and importance of arrangement of description, excluding the chapter 8 is conclusion we can say like this from the chapter 3 to the chapter 7. In the chapter 3, we explain GOVT we are using now and description element category in situation and problem of arrangement of description in Archives. In the chapter 4, this is about guideline from Archives in U.S.A, England and Australia. 1. Lifecycle Date Requirement Guide from NARA is introduced and of the description field, the way of the description about just one title element is introduced. 2. This is about the guideline of the description from Public Record Office. That name is National Archives Cataloguing Guidelines Introduction. We are saying "PROCAT" from this guideline and the seven procedure of description. 3. This is about Commomon Record Series from National Archives of Australia. we studied Registration & description procedures for CRS system. In the chapter 5, This is about the example which applied ISAD to. Archives introduce description of documents produced from Appeals Commission in the Ministry of Government Administration. In the chapter 6, 7. These are about the problems we pointed after using ISAD, naming for the document at procedure section in every institution, the lack of description fields category, the sort or classification of the kind or form, the reference or identified number, the absence description rule about the details, function classification, multi-level description, input format, arrangement of book shelf, authority control. The plan for improving are that problems. The best way for arrangement and description in Archives is to examine the standard, guideline, manual from archives in the advanced countries. So we suggested we need many research and study about this in the academic field.

Cable-stayed bridges are attractive due to their beauty, reducing material consumption, less harm to the environment and so on, in comparison with other kinds of bridges. As a massive structure with long period and low damping (0.3 to 2%) under many dynamic loads, these bridges are susceptible to fatigue, serviceability disorder, damage or even collapse. Tuned Mass Damper (TMD) is a suitable controlling system to reduce the vibrations and prevent the threats in such bridges. In this paper, Multi Tuned Mass Damper (MTMD) system is added to the Ahvaz cable stayed Bridge in Iran, to reduce its seismic vibrations. First, the bridge is modeled in SAP2000 followed with result verification. Dead and live loads and the moving loads have been assigned to the bridge. Then the finite element model is developed in OpenSees, with the goal of running a nonlinear time-history analysis. Three far-field and three near-field earthquake records are imposed to the model after scaling to the PGA of 0.25 g, 0.4 g, 0.55 g and 0.7 g. Two MTMD systems, passive and active, with the number of TMDs from 1 to 8, are placed in specific points of the main span of bridge, adding a total mass ratio of 1 to 10% to the bridge. The parameters of the TMDs are optimized using Genetic Algorithm (GA). Also, the optimum force for active control is achieved by Fuzzy Logic Control (FLC). The results showed that the maximum displacement of the center of the bridge main span reduced 33% and 48% respectively by adding passive and active MTMD systems. The RMS of displacement reduced 37% and 47%, the velocity 36% and 42% and also the base shear in pylons, 27% and 47%, respectively by adding passive and active systems, in the best cases.

Since 1990s, many companies or enterprises have been interested in Career Development or Career Management of Personnel in Korea. In the result of those interesting, some companies developed or built a program or computer system on Career Development or Career Management for their personnel. But their systems or programs are just the level to mange what kind of on-the-job training taken, ones experience where he or she worked, one who has a certificate of qualification ring a position and etc. This is not fit the field of construction industry and is not sufficient to mange workers at a construction company and their career. Because a construction project success depends on ones ability including know-how, skill and experience and these dependence is higher than any other industry's projects. The level of management on the career of construction company's personnel should be lower and expended than now and the career management of a construction company should include individual experience and personal history(period attained a project or a work, what kind of project or work, and etc)attained in performing each construction project and show ones career development process to each person. This system gives participants a chance to educate oneself and evaluate the level of ones training by showing individual records to each member of staff. And the company gains the advantage of the staffs ability to easily solve problems as well as the improvement of the organizations capabilities.

Objective : The tethered cord syndrome results in progressive neurological deficits. Although it may remain controversial, many physicians recommend definitive surgery to untether the cord as soon as this condition is identified. We retrospectively evaluate the pre-operative and post-operative course of 38 tethered cord patients with spinal dysraphism in an attempt to learn the natural history of the disease and to determine the effectiveness of the surgical treatment. Methods : The medical records, operation notes and radiographs were evaluated. The follow up period ranged from 4 months to 12 years with a mean follow-up of 28.6 months. Twenty-seven patients were younger than 15 years of age. Results : At presentation, 26 of the patients were asymptomatic. In three of 11 adult symptomatic patients, their neurological deficits worsened after trauma or exercise. Improvement of motor strength was documented in two out of 5 patients. Five of nine patients with bladder symptoms improved, however, none had a complete return of their bladder function. Conclusion : Childhood patients were less symptomatic than the adult patients. Adult patients showed progression of their symptoms that were not improved even after the operation in most of the cases. Asymptomatic tethered spinal cord can be symptomatic as time passes by and even at an old age. Future research should be focused on the operative methods to prevent the delayed deterioration after surgery, rather than on the usefulness of preventive surgery in asymptomatic patients.

This study explored the factors affecting the acceptance of public recording in SNS post. Using SPSS 21.0 program and AMOS 21.0 program, major results were derived through exploratory factor analysis, confirmatory factor analysis, correlation analysis, and path analysis. The results are as follows: First, the risk of personal information leakage on SNS posting has a significant negative impact on the attitude toward SNS posting. Second, the security of the SNS posting has a significant effect on the attitude toward the SNS posting. Third, the concern about privacy of SNS posting has a significant negative impact on the attitude toward SNS posting. Fourth, the attitude toward SNS posting has a significant effect on the intention to accept the SNS posting. The above results suggest that the SNS post recording should be able to collect opinions of SNS users from a long-term viewpoint.

This study is comprised of data obtained from the files of 346 patients with temporomandibular disorders. All patients were diagnosed, treated and followed in the Department of Dentistry at the Inha university hospital, Incheon, Korea. The patients had treated with medications, physical therapy, occlusal splint and arthrocentesis. The study data were obtained from the medical records and telephone interviews that were conducted by research assistants. The results were as follows 1. The patient's main complaint was pain(77%), and mouth opening limitation was 17%. 2. An analysis of the medical records of the 346 patients disclosed that 82% were improved and 17% had no improvement when they were dismissed. 1% of the patients had become worse during therapy. 3. A success rate of 82% was achieved when medication assisted physical therapy was included. In the current status at the telephone interview, 270 patients(89%) reported that they were doing well with 56% describing themselves as asymtomatic and 32% experiencing only minor residual or recurrent symptoms. 11% regarded themselves as unimproved and worse. 4. In the current status of the unsuccessfully treated patients by medications and physical therapy, 64% of patients were doing well(3% as asymptomatic and 56% as only minor residual or recurrent symptom). But 36% of patients was reported as unimproved and worse. 5. TMJ has a remarkable adaptive potential and TMJ disorder has a natural history of spontaneous fluctuations and favorable prognosis during the subsequent natural course. 6. In the treatment of the temporomandibular disorders, there is a treatment ladder, starting with the simplest and least expensive treatment, that is ascended until resolution of the patient's symptoms occur. These findings suggest that conservative reversible therapies are both sufficient and appropriate for management of temporomandibular disorder in most patients. Major alterations of mandibular position or dentoalveolar relationships do not appear to be necessary for obtaining either short term or long term success and therefore they can be generally regards as inappropriate treatment for this disorder. The fact that physical therapy is non-invasive and does not appear to be fraught with irreversible changes, makes it a very applicable vehicle in the area of clinical TMJ disorder management.

This study concerns Sama Pangmok which is in the possession of Harvard-Yenching Library, Harvard University, USA. Sama Pangmok is the archive of Saengwon Chinsa Examination(the licentiate examination) which is the preliminary test for main civil service examination. And it is the list of the names of the applicants who passed this examination. This examination were conducted from the days of lauching of Chosun as a new nation to the days of Kabo Kyungjang(the 1894 reform). While this examination was conducted 230 times, not all but 186 of the resultant lists are available. Of these 186 lists, this library posses 47 titles. My study of the existing dissertation on the possession of titles by Harvard-Yenching Library, 7 titles where in possession of the same library in 1968 and 5 ones in 190. It is the main objective of this study to clarify the possession of this library and correct the past errors in indication of possession of titles by this library. For this purpose, I conducted a study on Saengwon Chinsa Examination and Sama Pangmok, which could be the historical background of this study. This was followed by research on the bibliographical aspect of Sama Pangmok and the research on the situation concerning this Library's possession of the same lists. Lastly, the analysis of the special feature of Sama Pangmok possessed by this Library was conducted. It is expected that the result of this research will be applied to the practical research of the history of civil service examinations and the old and rare books overseas in the future.

We, currently settled on the peninsula, have a long history and our ancestors lived over the vast land further to the central Asia and northern China. Normally, our ancestors traded with many countries, but they fought battles when they were on bad terms and many countries emerged and disappeared. In this history, a variety of cultures have been established and the traditional martial arts is a part of those cultures. Our martial arts has been almost severed because of the development of fire weapons in the late Chosun Dynasty, Japan's colonial rule, and 1950-53 Korean War. Fortunately, we can study the traditional martial arts from history books, the records on the martial art books and relics. Muyeadobotongji, the martial art book published in the late Chosun Dynasty, regrets the negligence of martial arts Giyae(arts) after Japanese Invasion of Korea in 1592 and the Manchu war of 1636 and accommodated the martial art skills from Chosun, China and Japan. It is useful for studying martial arts, because it contains detailed description and drawings, clothes and accessories, and the specification of the weapons. However, the problem is the level of Giyae of the martial arts organization and individuals based on Muyeadobotongji vary and some organizations are arguing about the numbers.
