  • 네트워크 기술의 발전으로 사회 여러 분야에서 인터넷을 이용하여 다양한 서비스들이 제공되고 있다. 이러한 서비스가 널리 확산됨에 따라 인터넷 상에서 전송되는 정보의 기밀성과 무결성을 보장하기 위한 암호 기술이 크게 주목을 받고 있다. 현재 널리 사용되고 있는 암호 알고리즘으로는 FIPS 197(Federal Information Processing Standard)에서 정의한 AES(Advanced Encryption Standard)와 FIPS 46-3에 채택된 Triple DES(Data Encryption Standard), FIPS 198에 정의된 HMAC 등이 있다. 이러한 알고리즘들은 시스템 사이의 상호 운용을 위해 제정되었으며, 공유 키 재료(Shared keying material) 설정이 사전에 이뤄져야 한다. 키 재료의 설정은 신뢰기관에 의해 분배가 가능하나, 객체의 수가 증가함에 따라 키 재료 분배 작업이 지수적으로 증가하게 되는 문제점이 있다. 그러므로, 본고에서는 이러한 키 재료 분배의 문제점과 효율적인 키 설정 스킴에 대하여 기술하고 있는 NIST 800-56을 분석하고자 한다.

  • A conductor has been produced according to IEC standard and low voltage electrical facility has been installed according to IEC 60364. But because of many related and varied standards, it is difficult to apply to design and inspect for electrical equipment. We researched the necessity of design guide which is detailed and systematization from survey. For detailed design guide, we suggest application method and review items at calculations for voltage drop calculations on low voltage feeder by IEC 60364, BS 7671 standard and Consumer's Electrical Installation Guide.

  • Over the past ten years, a new knowledge-based information society is coming up with a new paradigm shifted from the Industrial Society. According to this paradigm, Korea's policies of informatization on public administration affairs are shaped and promoted by several responsible bodies, including the Ministry of Government administration and Home affairs, the National Computerization Agency, as well as central and local Governments. But most informatization actions, especially standard information system projects, have done separately by the Ministries of central government. Besides, because of the absence of informatization strategy in local governments such as cities, counties, etc., they pursue separately various informatization projects on administration affairs by divisions. It is a critical problem not to manage systematic and unified promotion of information systems policies on administration affairs in local government. As an initial attempt to tackle the problem listed above, by introducing systems thinking this paper puts an effort to find some tentative answers to solve the problem possibly raised about the impact by Standard Information System Policy on which little research has been conducted so far. The findings presented in the paper would perhaps provide some ideas and directions for further study.

  • Anti-terrorism design for public buildings as well as military facilities is important to minimize the mass casualties from terrorist attacks. Also, well designed glazing and window systems can reduce the potential injury of human caused by scattering fragment of a glazing. In this paper, blast resistant design for glazing and window systems is investigated based on the U.S. Standard. The design procedures include minimum requirements for the design, standard practice for design evaluation of the glazing and standard test method for evaluation of the performance.

  • Dimensional difference by welding deformation is usually occurred at steel bridge manufacturting or multi-pass welding used at joining of thick plates. Be this, root gap out of standard is frequently developed at butt weld joints. For example, although standard root gap below 6mm at butt weld joints of plates under 15mm thickness, maximum 30mm root opening is developed at the weld field. At this case, 24mm parts out of standard is generally built up. But, there are no accumulated data and restriction about this built up welding pars. In this study, therefore, the accumulation of data for built up parts and the verification of the mechanical properties of weld part as root gap is performed. It is included that tensile, bending, impact, hardness test and microstructural review for each welding specimen of 0mm, 6mm, 30mm root opening.

  • The purpose of this study is to propose empirically the improvement measures of labor conditions of the contingent worker. Since early 1980s, the labour market in Korea has given rise to a rapid growth in contingent worker. Last year, the number has shot over 7 million mark, with the ratio standing above the 50%. This study analyses the improvement measures of labor conditions of the contingent worker. This study present five major improvement measures of labor conditions of the contingent worker. First, It's establish of the relations between organizational flexibility of the labour market and the contingent worker. Second, It's needs to realize wages level of the contingent worker. Third, the contingent worker convert standard workforce step by step. Fourth, it's make no discrimination of the between contingent worker and standard workforce. Fifthly, the government place restrictions of the contingent worker rates.

  • Although NMR technique has been using in many areas of chemistry, its merit on quantitative analysis seems not to acknowledge greatly because of the many inferior intrinsic aspects, particularly its sensitivity. Recently, new NMR techniques, high-field NMR, and demands for cutting edge techniques of analysis, however, seem to change the role of NMR spectroscopy in this field. This review shows the application of NMR development in quantitative analysis and will discuss the basic idea, limitations, and pitfalls. Then it will show you several successful applications applied in quantitative analysis and you will see how useful and accurate method it is.

  • A construction temporary work is main process and importance trade section. A technology system of construction temporary has very low availability of field works and needs improvements in Korea as construction site has a quick response about new requirements. This study reviews literature researches and can verify that changes to a comprehensive technology system for construction site. In addition, it suggests a breakdown structure of new standards for temporary construction technology based on views of construction site managers. Meanwhile, temporary construction technology in Korea has changed with a specification of construction temporary work which had been revised in 2014. However, the revision is merely dividing the design and building off of construction temporary technology. It is lacking in many ways to change this in a new standard system for temporary construction technology. Henceforth, it needs to develop a standard system for temporary construction technology and a professional system that is appropriate for different purposes by detail trade sections.

  • This descriptive study was conducted in order to develop a standard criteria for nursing laboratory facilities and equipment for use by the 3 year nursing colleges. The data was collected from Aug. 28 to Sept. 30, 1997 by mail from 44 3 year nursing schools. To develop a standard criteria, the syllabi for Fundamentals of Nursing laboratory and for Physical Assessment were collected and analyzed. The following information was elicited and analyzed by the researchers : 1. for each procedure in the syllabus, the percentage of schools using the procedures 2. the facilities and equipment recognized as necessary and the percentage of schools which possess each item 3. calculation of the standard criteria for size of the nursing laboratory together with a list of the necessary facilities and equipment. The results of the study were as follows : 1. The Size of facility was 181.2m2 for fundamentals of Nursing laboratory and 56.4m2 for the storage room. For those whose number of students exceed 120, 1.98m2 is required for each students. 2. The number of items included in the standard criteria was 92 for Fundamentals of Nursing and Physical Assessment and 47 for other nursing subjects. The items made of rubber, plastic and the disposable ones were suggested but excluded from the standard criteria. Based on the above findings, the following suggestions were made : 1. Periodic review of the standard criteria is necessary to update the standard. 2. A study on the standardization of the curriculum for basic science laboratory, including experiment and a standard criteria of equipment, is necessary. 3. A study to develop a computer program for management of nursing laboratory facilities and equipment is needed.
