  • This study started from the awareness of the issue if the citation index newly introduced to evaluate the quality of papers satisfies the proper timing matter, which is a component of performance indicators for the evaluation of government-funded R&D institutes. Accordingly, the study will propose improvement ways to shift the previous evaluation system to quality evaluation for mission-oriented R&D institutes by analysing and using the periodical characteristics such as citation half-life and immediacy index of papers. As a result, it turned out that the speed of academic change is getting faster in proportion to the dependency on the technological development but that the citation speed in the field of public technology is relatively slower and the speed of knowledge transfer in the fields related to industry is faster. In addition, the citation index among the R&D fields showed no differences, and the minimum period for citation index measurement with validity should be over 6 years. The problems of evaluation for mission-oriented R&D institutes were deducted based on the technical and statistical analysis results of the temporal characteristic of citation necessary for quality evaluation of performance among R&D fields. To solve the problems, policy alternatives for object and valid quality evaluation were proposed from the points of evaluation period, evaluation criteria, and evaluation management.

  • Metal prices are rapidly rising due to increasing demand of metals and limited available resources according to the industrial requirement. As a result, securing a stable supply of these metal resources has been recognized as a core element of national competitiveness and sustained economic growth. In the case of magnesium and its alloys which are entirely depending on import, low-grade magnesium scraps from end-of-life vehicles and 3C(Camera, Computer, Communication) parts and magnesium wastes such as sludge and dross generated during melting process are hardly recycled. Accordingly, the development and commercialization of recycling technology of low-grade magnesium scrap is desperately needed to improve efficiency of resource circulation and to establish the required proprietary of resource metal supply and demand. In this study, papers and patents on recycling technologies of waste magnesium were analyzed. The range of search was limited in the open patents of USA (US), European Union (EP), Japan (JP), Korea (KR) and SCI journals from 1974 to 2012. Patents and journals were collected using key-words searching and filtered by filtering criteria. The trends of the patents and journals was analyzed by the years, countries, companies, and technologies.

  • As the scales & density of the Korean national infrastructures have been increased, they will be identified as rich and attractive potential targets for intensified North Korea's attack in the rear region and terrorism attack. In addition, due to changes in security environment such as drone threats and lack of security forces under the 52-hour workweek law, I think that it is the proper time point to reevaluate the effectiveness and appropriateness of the current physical protection system and its shift to a new system. In this study, the direction and improvement of the perimeter physical protection systems of the national infrastructures are to be studied from the viewpoints of its concepts of operations and design methodology, focusing on the nuclear power plant. The reason why we focus on nuclear power plants is because they cause wide-range and long-term damages caused by radioactive materials disperal and pollution, along with short-term damage caused by the interruption of electricity generation in the event of damage to nuclear power plants. With the aim of extracting improvement directions, as we will comprehensively review domestic research trends and domestic·overseas related laws, and consider Korea's specificity, we try to reframe the concept of operation - systematization, mobilization and flexibility -, and establish criteria on system change. In order to improve the technical performance of the new perimeter physical protection system, we study on high-fidelity·multi-methodology based integrated design methodology, breaking from individual silo-type design methods, and I suggest improvement of government procurement, its expansion to export business and other national infrastructure.

  • Digital forensics is the process of uncovering and interpreting electronic data and materials found in digital device in relation to crime. The goal of the process is to preserve any evidence in its most original form which shall be having the force of law. The digital forensic market is increasing with a growth of ICT in domestic and global market. Many countries including U.S. are actively performing researched regarding a structured investigation by collecting, identifying and validating the digital information for the purpose of reconstructing past events which so does in academic society in Korea. This paper is to understand overall research trend about digital forensics and derive future strategy by integrating the result of meta-analysis into practices based on five criteria - main theme and topic, analysis phase, technical method for analysis, author's affiliation, and unit of analysis and method. 239 papers are analyzed, which were selected out of 470 papers published for 10 years (2007~2016) in academic journal on the list of KCI (Korea Citation index). The results of this analysis will be used to examine the characteristics of research in the field of digital forensics. The result of this research will contribute to understanding of the research trend and characteristics leading the technology-driven academia, through which measures for further research development and facilitation are suggested.

  • A methodology has been presented for evaluating the partial safety factors on the sliding failure mode of vertical caissons of composite breakwaters and for determining the cross sections of those by Level I reliability-based design method. Especially, a mathematical model has been suggested for the sake of a consistency of code format as well as convenience of application in practical design, for which the uncertainties associated with buoyancy and its own weight can be taken into account straightforwardly. Furthermore, design criteria equation has been derived by considering accurately the effect of uplift pressure, so that the cross sections of caissons can be assessed which must be safe against the sliding failure. It has been found that cross sections estimated from partial safety factors proposed in this paper are in very good agreement with the results of Level II AFDA and Level III MCS under the same target probability of failure. However, partial safety factors of the Technical Standards and Commentaries for Port and Harbour Facilities in Japan and Coastal Engineering Manual in USA tend to estimate much bigger or smaller cross sections in comparison to the present results. Finally, many reliability re-analyses have been performed in order to conform whether the stability level of cross section estimated by Level I reliability-based design method is satisfied with the target probability of failure of partial safety factors or not.

  • This study analyzed problems of operating performance bond for public works and derived some suggestions for improvement. The Contract Law for Government Owner requires to submit performance bond which guarantees performing the construction contractor pays back compensation money when the obligation is not executed. Currently, first bid eligibility for participation is exactly required for executing company of performance bond obligation, not considering volume, technical level, and special type of remaining works. In collaboration contract, if guarantee accident occurs, it is obliged for remaining collaboration contractors to be qualified to fulfill the whole contract. This study proposes following improvement plan to solve problems of current performance bone in public works. Firstly, qualification criteria must be deregulated exceptionally for selecting proper contractor, which executing performance bond obligation, considering progress and characteristics of remaining works. Secondly, In collaboration contract, the prerequisite of remaining contractors' should be deregulated as 'implementation requirement of the remaining works'from'implementation requirement of the whole work'. Finally, defect responsibility should be included in liabilities of performance bond by specifying that owner or guarantee agency bear them.

  • The collection and transfer of records is a very basic stage in the whole process of records and archives management. However they are regarded as an non-professional art of work in records management that are performed easily by everyone. Therefore they have been treated not properly in the scholarly discussion of archival sciences in Korea. The collection and transfer of records play an active role in the making of effective administrative system, in accumulating and sharing the knowledge and informations of political, economical, social and cultural values. On the basis of proper collection and transfer of records our democracy can operate regularly and our daily experiences can be preserved as historical resources. For the optimal-functioned collection and transfer of public records the archivists for this task must have a comprehensive understanding of whole process of records management and possess suitable professional skills. Moreover there are many sorts of preliminary works needed for this task, as follows: an accurate defining of administrative organizations and their tasks, thorough understanding of records management institutions on their own competence and ability, and the establishment of technical standards for their tasks. Additionally the archivists are able not only to consider the present informational and evidential values of the records, but also the historical values. It can be said that the collection and transfer of records is a "synthesis of records management skills" exerted by an archivist. According to the newly established law of public records management, the collection and transfer of public records must be registered at first electronically. Through this procedure the whole contents of produced and transmitted records, which are to be transferred, can be reported in detail. By means of this report the archival institutions and the archivists can trace back the each items of records(archives) and the result of their arrangement to identify a certain object. There are also new storage strategies employed to increase the whole sum of stored informations, i. e. records and archives, in spite of reducing the storage costs. It will be achieved by differentiations of the preservation methods for each sorts of records by the criteria of storage-period, -place, and -method. Many supplementary methods are also prepared to help the collection of important records(archives) in a complete structure and form. To let this new concept and system of collection and transfer of records operate properly, a number of professional archivists should be posted in the needed places throughout the whole administrative body. Their training must be also updated for the newly defined task of collection and transfer of records.

  • Korea was highly successful in maintaining a strong tradition of record preservation. However, Japanese imperialism and the Korean war over this century has seen a huge quantity of these once plentiful records either destroyed or relocated overseas. Many of Korea records remain in the custody of foreign archival institutions. Additionally, many records of foreign states concerned with korean affairs, for example, records of the Department of state, in the U.S.A., are of great relevance to Korean modern history. These records which exist in foreign countries are a necessary and invaluable resource in the advancement of Korea studies. After the 1980s, as research interest in Korean modern history increased gradually, much historical material related to Korea was extensively introduced, removed, collected from the U.S.A., Japan, Russia and China etc. by the efforts of pioneering scholars and institutions. Several attempts at collating and publishing this material have been made. Despite this encouraging result, individual scholars and institutions's efforts face problems in relation to removal of records. Firstly, it is repeated nonproductively to remove and collect the same records, for we didn't establish a comprehensive information system, through which the condition of foreign record removal and management is able to be administrated. Secondly, there is no system for arrangement, preservation, use of removed records. For example, finding aids, such as inventory, register, description, isn't prepared for user. A user may usually not understand an accurate context of their creation, preservation removal. Thirdly, almost institution has arranged the removed records among other materials and books. Each institution has a different classification criteria, too. These conditions seem to make a difficulty in national management. This study investigated how the materials for Korea history which has been removed from foreign countries should be managed for effective preservation and use. For these purpose, we investigated the present conditions of removal and management of these materials. Also, we investigated examples of the foreign state, U.S.A. and Japan to have a idea for removal and management policy. Then, This study propose a establishment of information network system as management policy. To administrate removing and managing records effectively, an idea that records belong to the public should be accepted commonly. The policy for management of the record is followings. Firstly, unification of classification is necessary. The records which were removed from foreign countries had better to be classified according to their origins of states and institutions. Secondly, Finding aids should be prepared for user. There are many accession aids such as catalog, register, inventory for user in archives. This will be a efficient method for management. When a record is removed, a card for description of contents must be composed. Thirdly, a digital input and network system establishment is necessary. It will help to manage a condition of removed records. A digital input and management system establishment is not just a project of digitalizing records. At present, various finding aids need to be introduced to make a database for records and archives. An search using only 'search engine' may make a difficulty in finding materials because such method is apt to have too much or little result. So, classification, arrangement, description, response-service should be integrated in these system. The recent technical advancement give a opportunity to realize this idea. Above all, these procedure should be archival process.
