  • This study was designed to survey misused expression in 37 KS (Korean Industrial standards) related to personal protective equipment. The results were as follows: 1. One hundred and twenty five misused expressions were found - 44 expressions were used illogically (35.2 %). 80 expressions were wrongly described (64.0 %) The types of illogically misused are: 10 illogical cases, 4 cases of a wrongly designated provision when cited, 12 cases of the lack of provisons for KS, 7 cases of a inappropriate uses of units, 8 cases of an overlapped sizes between standards. - The types of expressions wrongly described are: 30 cases of confusion in using an terms, 4 case of making an error when proofreading, and 29 cases of choosing words not appropriate to describe technical standard, 18 cases of unclear provisons due to missing phrases and terms, and 11 cases of provisons described differently from original intended purposes. 2. There is one case, where the same standard is categorized as two different names. There are three major causes of the misused expressions as seen from the following summary: - Imitated the developed countries' standards without filtering them by considering domestic law and ocher KS standards. - Tended to create each definition for each standard instead use of the basic standard. - Insufficiency of synthetic examination to the correlation between standards.

  • A numerical analysis based on two-dimensional, incompressible and compressible Navier-Stokes equations was carried out for double circular arc compressor cascade and the results are compared with available experimental data. The incompressible code based on SIMPLE algorithm adopts pressure weighted method and hybrid scheme for the convective terms. The compressible code with preconditioning method involves a upwind-biased scheme for the convective terms and LU-SGS scheme for temporal integration. Several turbulence models are evaluated by computing the turbulent viscous flows; Baldwin-Lomax, standard $\kappa$ -$\varepsilon$, $\kappa$ -$\varepsilon$ Lam. Bremhorst, standard $\kappa$-$\omega$, $\kappa$ -$\omega$ SST model.

  • The purpose of this study was to investigate whether the standard models for rural housing and wooden housing model have performance for hygrothermal and to propose a way of improvement relevant to hygrothermal performance for those models. All of the models to be analyzed were found to have some parts that were absent of stability in terms of performance for hygrothermal. In the process of analyzing the causes and proposing improvement measures, the following conclusions were derived. Fist, The exterior surface of the structure should be composed of a structure with good moisture permeability, and for the interior surface, a variable vapor retarder paper should be applied in consideration of the reverse condensation phenomenon in summer. Second, in terms of performance for hygrothermal, applications of external insulation plaster finish to the exterior wall or of ventilation method using a rafter vent on the roof should be avoided. Third, a rain screen method with a ventilation layer should be applied to the exterior wall, and a method of constructing ventilation layer separated from the insulation layer with a vapor retarder paper should be applied to the roof. Fourth, the application of insulation materials having capillary action, such as wood fiber insulation board or cellulose insulation board, contributes to more stable performance for hygrothermal.

  • Interoperability tests are required to determine whether network-based defense systems successfully share and exchange certain services, information, and data. We must examine various aspects of interoperability. The DITA (Defense Information Technical stAndard) is the basis for interoperability. However, DITA is being applied to the defense system in a state that the standard test methods and procedures are not established. And there is no test method and procedure of the DITA well applicable to military weapons systems or information systems. Therefore, in this paper, we propose a framework that includes procedures, methodologies, so as to test whether a standard is applied to the DITA in terms of Standard Conformance Test.

  • The purpose of this research is to develop a basic pattern of corset look taking into consideration characteristics of human body and fit, by transforming 3 dimensional information obtained from draping of standard body type of women in their 20s, which constitute the biggest consumer group of corset look in Korea, on the basis of body shape of women best reflecting 3 dimensional characteristics. In order to develop a corset look pattern suitable for standard body type of women in their 20s, wear tests of A, B, and C types of patterns in terms of the bust in the standard body type that bust circumference 86.7cm and chest circumference 87.0cm were evaluated best. Taking into consideration above findings, fer the purpose of developing a corset look pattern having an excellent fit and reflecting characteristics of Korean women in their 20s with standard body type, a corset look pattern was designed with proper ease calculated by draping incorporated, and through alteration and complementation of such a pattern, a study pattern was produced. This study is expected to provide tips for standard body type women in their 20s with smaller bust circumference to choose clothing allowing for a better fit able to make up for weakness of their body, while presenting to clothing makers ways of designing and size-setting in terms of characteristics of body type of these consumers.

  • Oriented strand board (OSB) distributed in Korea was collected, and its mechanical properties were investigated according to the International Organization for Standardization (ISO), Japanese Industrial Standards, and Korean Design Standard. Ten types of OSBs were collected, including six types for walls and others for floors. The thickness swelling, moisture content, and density of each product satisfied the ISO standards. All products showed lower formaldehyde emission values than those of the SE0 grade. The internal bonding strengths of all products, except products B, H, and I, met the ISO standards. However, products A, B, C, F, and H did not satisfy the thickness swelling standard of the load-bearing OSB for use in dry conditions. Products D and G showed heavy duty load-bearing OSB for use in humid conditions in terms of internal bonding and bending strength after boiling. In the nail head pull-through force and lateral nail resistance tests, all products met the standards. In terms of the structural bending performance (four points), the six types of OSBs for walls satisfied the standard for bending strength and modulus of elasticity. All the products for flooring met the standard for bending strength but, except for product G, the products did not meet the standard for modulus of elasticity. Although the results of this study cannot represent the performance of all imported OSBs, considering the above results, the water resistance performance of seven types of OSB products did not meet the standard, and 10 types of products did not match the labeling grades.

  • ISO 9000 is a series of several standards(ISO 8402, 9000, 9001, 9002, 9003, 9004,...). ISO 9000 is a standard explaining fundamental concepts, defining important terms, and providing guidance for selecting among the other standards. ISO 9001, the most comprehensive standard to ensure quality in design, development, production, installation, and servicing. ISO 9002 is used to assure conformance to specification, installation and servicing. ISO 9003 has the least requirement among three standards and applies to inspection and final testing. ISO 9004 is a standard developed for internal use only and not applicabe to contractual arrangements. In this paper, quality system requirements for ISO 9000 series are also specified.

  • Objective : Up to the present, theories of medical books is too difficult to understand thoroughly. However, these study methods have some problems in dealing with lots of meaning because the comprehension of theories are dependent upon one's memory. Especially, comparison distinct medical books are more difficult matter. So, we have attempted to solve a problem. Method : We have researched medical terms in the "Piweilun" according to below the procedure. (1) Making a terms list: We have selected constituent of sentence. And we have made term list on the basis of concept of term. (2) Making a synonym list: We have collected identical conception and made a synonym list. So, using an synonym tables of DB, it is possible to search for the non-standard terms of medical theory. (3) Making a classification system: Using UMLS(Unified Medical Language System), MeSH(Medical Subject Headings), IST(International Standard Terminology) ect., we have made a classification system of oriental medicine terms in the "Piwelun". Analysis of relation between terms. Result : In the "Piweilun", there are more than 1,790s concepts. Parts of those are belonged to UMLS-Semantic Type, the other parts of those are not belonged to UMLS-Semantic Type. And those include predicate more than UMLS-Semantic Relations.

  • ‘Guidebook of Standard Agreement in Korea Cartoon Business’ was officially announced by Korea Culture & Content Agency. We try to make this as a standard agreement for both cartoonist and publisher through mating the most of it. As this ‘standard agreement’ is the result of government sponsored research, it ought to be used for the profits of both, cartoonist and publisher. After investigation for unequal terms if any , I tried to find other alternatives for the development of this part. The objectives of my study is as follows; first, for the circumstance in which cartoonists can be devoted to his work without any insecurity in the part of ‘agreement’. Second, publisher can publish more of good contents with the help of those cartoonists.
