Korean government, port and logistics companies have given a lot of their efforts to exchange electronic documents between themselves and their partners. As the results of them, Korean EDI(Electronic Data Interchange) standards were made by Korean EDIFACT committee and the standards have been used by companies and governmental organizations in Korea. However, Korean port and logistics EDI system is based on YAN(Value Added Network) and one VAN company has monopolistic right to relay EDI documents to Korean HOMAF(Ministry of Maritime Affairs & Fisheries) and Customs Service. Therefore it leads to a lot of problems such as inconvenient software, expensive transmission fee, insufficient improvement of business process and the difficulty of connection with the in-house systems of user companies. For solving these problems, this study is aimed to progress for XML and XML-based electronic commerce framework. This paper shows a optimal XML/EDl method using XML/EDl, BizTalk Framework, ebXML Framework. Fer improving extant problems in port and logistics industry, this paper proposed XML/EDl system based on system architectural level, support technical level, business infrastructure level.

Through the correspondence works with international electrotechnical vocabulary(IEV) in the smart grid field and power information technology field, we analyzed cases for discussion of terms and definitions in the IEV and then proposed an advanced procedure and computing system for standardization of International Electronical Committee(IEC) terminologies. The standardization procedure consists of processes for existing terminology, new terminology and correspondent terminology which have different structures. An example of the standardization work of correspondent terminology is given. The standardization computing system are based on the process for terminology extraction, terminology verification and terminology management which could provide the Wikipedia type terminology search function. In order to prevent that there exist multiple terminologies in IEV, the database search system is needed to be developed. We proposed the 'IEV_Term_Search' program which is the database search system. Terminology standardization of different technical committees(TC) and completion of the IEV to promote cooperation between TC 1 and the TCs must be followed by revision and standardization using the standardization computing system.

This paper is based on our comments and proposed amendments to the documents, Annex A, Phantom for determining Maximum Depth of Penetration, and Annex B, Local Dynamic Range Using Acoustical Test Objects 87/400/CDV. IEC 61391-2 Ed. 1.0 200X, prepared by IEC technical Committee 87; Ultrasonics. The documents are concerned with the influence of microstructure of reference target material on the ultrasonic backscattering. Previous works on the attenuation due to backreflection and backscattering of reference target materials are reviewed. The drawback to the use of ungraded stainless steel and metallic materials without microstructural data such as, crystal structure, basic acoustic data of sound velocity and attenuation, grain size, roughness and elastic constants has been discussed. The analysis suggested that the insightful conclusion can be made by differentiating the influence arising from target size and microstructure on the backscattering measurements. The microstructural parameters are associated with physical, geometrical, acoustical and mechanical origins of variation with frequency. Further clarification of such a diverse source mechanisms for ultrasonic backscattering would make the target material and its application for medical diagnosis and therapy simpler and more reliable.

Increasing the development of human life as a medicine and has emerged smart health care according to this. Organic and efficient health management becomes possible to generate a vector when the biological domain to the wireless communication infrastructure based on the measurement of the health status and to take action in accordance with the change of the physical condition. In this paper, we propose a framework to create a bio-vector that contains information about the current state of health of the person. In the proposed framework, Bio vectors may be generated by collecting the biometric data such as blood pressure, pulse, body weight. Biometric data is the raw data from the bio-vector. The scope of the primary data can be set to active. As the collecting biometric data from multiple items of the bio-recognition vectors may increase. The resulting bio-vector is used as a measure to determine the current health of the person. Bio-vector generating the proposed framework, it can aid in the efficiency and systemic health of healthcare for the individual.

A growing fatigue crack is known to be retarded on application of an overload cycle. The retardation may be characterized by the total number of cycles involved during retardation and the retarded crack length. The overload ratio plays an important role to influence the retardation behavior. The objective of the present investigation is to study the effect of different overload ratio on the retardation behavior. For DENT(double edge notched tension) specimens and ESET(eccentrically-loaded single edge crack tension) specimens, fatigue crack growth tests are conducted under cyclic constant-amplitude loading including a single tensile overloading with different overload ratios. The proposed crack retardation model predicts crack growth retardation due to a single tensile overloading. The predictions are put into comparison with the experimental results to confirm the reliability of this model.

The study Is Intended to investigate and analyze the system and practice that have been applied to Interior Architecture, comparing with a number of similar foreign cases, in an attempt to seek the way toward its development as well as to come up with the solution for enhancing the competitiveness, thereby making a recommendation on how to create the desirable work environment of Interior Architecture down the road. The conclusion and recommendation we have made is highlighted as follow. Among the practical or procedural challenges in the process of improving work environment of Interior Architecture, development of current national technical qualification system in a way of further detailing the categories of Ki-sul-sa(highest engineer grade) or Ki-neung-jang(highest technician grade) as part of measures aimed at gradual approaching for improvement of design fees and rates or supervision fees will be very crucial, that calls for close coordination with the Ministry of Labor and Human Resources Development Service of Korea. In a bid to upgrade the Interior Architecture to become the part of knowledge-based industry, amendment to Korean Standard Industrial Classification along with Standard Classification of Occupations and Academic Classification will be essential, and moreover with the attitude of reflection and self-improvement, the endeavors to be able to deal with the revision of existing laws and regulations in a consistent way and manner, by forming a joint committee among the three Interior Architecture-related organizations(KOSID, ICC, KlID), will be more than important.
