  • Existing research on international standardization has largely taken a qualitative approach focusing on comparative studies of national institutions and policies on standards or international rivalries from the perspectives of international relations or innovation studies. While there exists a handful of quantitative studies, they are mostly confined to simple numeric counts of essential patents, new work item proposals, or secretaries staffing international standards development organizations (SDOs). This study aims to contribute to our understanding of the dynamics of international standardization by the analysis of the data coding systematically national activities in the standardization process of the International Organization for Standardization (ISO), by far the largest international SDO. Our analysis of the four critical types of standardization documents generated in the Working Group 7 of the ISO/IEC Joint Technical Committee 1 reveals interesting dynamics among key players of global ICT standards regime. First, while the US takes a dominant share of the personnel as well as new work item proposals for standardization, its quality of activities rather falls behind as it mostly focuses on keeping in check other countries' standardization activities. Second, European countries tend to spread their effort evenly across different types of standardization activities. Finally, despite such differences between the US and European countries, both rely heavily on multinational companies to gain an advantage in the voting stage of standardization process.

  • High voltage electric power transmitter GIS(Gas Insulated Switchgear) above 72.5kV needs to satisfy domestic Korean peninsular standard(ES-6110-0002) in KEPCO with respect to normal and special operation conditions which include internal gas pressure, dead weight, wind and seismic load. Some other requirements not described in Korean standard can be applied from other international standards such as IEC(International Electronical Committee) 62271-203 and 62271-207. The GIS is a kind of pressure vessel structure made of aluminum and filled with SF6 gas of internal pressure 0.4~0.5MPa. Finite element analysis of GIS is performed with such operational loads including seismic loading and the stability and reliability is determined according to ASME BPVC(Boiler and Pressure Vessel Code) SEC. VIII standard where the allowable stress level of the pressure vessel is suggested. The result shows that the stress of GIS is satisfied the allowable stress level and the safety factor is about 2.3 for Korean peninsular standard.

  • Diagnostic imaging systems play a critical role in obtaining anatomical images, which increases the frequency of inspection all over the world. However the likelihood that patients are exposed to relatively high radiation dose increases, which may lead to an increase of patient dose due to unnecessary radiation exposure unless appropriate management is accompanied. Thus the revised edition of IEC 60601-2-44 which is constancy tests for CT equipment which is designated as special medical equipment and is subject to safety management was studied. The results suggested the 3rd has been revised rationally in order to overcome the limitations in the 2nd by adopting clear and enhanced references, which implies the replacement of IEC 60601-2-44 2nd edition with IEC 60601-2-44 3rd will prevent the patients from the harm from improper medical equipment.

  • The post-evaluation system after construction projects can evaluate estimates of use demand, project cost, and project schedule estimated in the planning phase of construction projects in public sector. Thus, it was introduced in 2000 for the purpose of reduction in future errors during similar constructions by project orderer by referring the post-evaluation results. However, many barriers to the post-evaluation system after construction projects have been reported due to evaluation systems that lack objectivity and reliability and lack of main bodies that utilize the system. Thus, this study derived implications for improvements of the post-evaluation system in Korea by benchmarking building project evaluation system and management as well as utilization systems of developed nations. Then this study conducted a survey with experts who have experienced activities in the post-evaluation committee and members of post-evaluation for public project owners. Therefore it identified the need of installation of specialized post-evaluation institutions as well as functions and work tasks to be taken by specialized institutions. Based on the analysis results, this paper provided revision drafts of related legislations and guidelines to be effective in post-evaluation. Through the study results, many trial and errors can be reduced in similar projects in the future by performing in-depth analysis on large-scale construction projects and repeatedly applied building project practices can be improved to raise technical competitiveness if the specialized institution is installed.

  • Purpose: The purpose of this study is to review the indications of ankle lateral complex reconstruction using tendon graft. Materials and Methods: We searched PubMed using the index, "ankle, instability, lateral ligament, reconstruction" from 1990 to present (September 30, 2015). We excluded 1) modified Brőstrom operation (MBO), 2) conventional tenodesis surgery, 3) review article, 4) technical note, and 5) articles written in another foreign language. We reviewed 24 papers through the publication events, operational method, the indications of surgery, and the specific features of the patient group. Results: There were the indications of 1) previous ligament surgery failure, 2) situation when ligament repair is impossible due to the ligament defect, 3) severe instability (preoperative talar tilt >$15^{\circ}$, anterior draw >10 mm or the difference of contralateral side talar tilt >$5^{\circ}$, anterior draw >3 mm), and 4) overweight (body mass index >$30kg/m^2$). Other considerations included 1) generalized joint laxity and 2) workers, highly-demanded or athlete highly-affected by instability. Conclusion: The ankle lateral complex reconstruction using tendon graft could be indicated in patients with the possibility of MBO failure with several considerations.

  • The purpose of Radioactive Waste Acceptance Criteria(WAC) is to verify a radioactive waste compliance with radioactive disposal facility requirements in order to maintain a disposal facility's performance objectives and to ensure its safety. To develop WAC which is conformable with domestic disposal site conditions, we furthermore analysed the WAC of foreign disposal sites similar to the Kyung-Ju disposal site and the characteristics of various wastes which are being generated from Korea nuclear facilities. Radioactive WAC was developed in the technical cooperation with the Korea Atomic Energy Research Institute in consideration of characteristics of the wastes which are being generated from various facilities, waste generators' opinions and other conditions. The established criteria was also discussed and verified at an advisory committee which was comprised of some experts from universities, institutes and the industry. So radioactive WAC was developed to accept all wastes which are being generated from various nuclear facilities as much as possible, ensuring the safety of a disposal facility. But this developed waste acceptance criteria is not a criteria to accept all the present wastes generated from various nuclear facilities, so waste generators must seek an alternative treatment method for wastes which were not worth disposing of, and then they must treat the wastes more to be acceptable at a disposal site. The radioactive disposal facility WAC will continuously complement certain criteria related to a disposal concentration limit for individual radionuclide in order to ensure a long-term safety.

  • recently, world is progressing large quantity consumption with continuous Innovation and economic growth and pollution is accelerated at these process. Increase of industry activity and service that is point of corporation activity is discharging environmental pollutants at whole process to manufacture of end product and exhaust process from acquisition of raw material for accompanied product production hereupon. At the same time, being promoting resources consumption by that use much raw material, As a result, is becoming obstacle factors in sustainable development. So, corporation's responsibility for environmental protection is emphasized. Corporation which must prepare in green round or environmental problems should consider environmental effects that is happened over whole life of products that include waste treatment after raw material acquisition and use as well as selling end product simply. A Life Cycle Assessment techniques is normalized and standardized in International Standard Organization for technical committee 207(TC 207) world widely, and effort to apply in corporation's activity because mastering LCA techniques in domestic several corporations is undergone actively. Coming into effect of Kyoto's Protocol and International Organization for Standard 14000 series revision are presenting new survival principle in competition between country or corporation. LCA technique may become very useful means to corporation which wish to attempt environment management in real condition that awareness for environment is important. Also, An LCA to each product is going to cause big effects in corporation's whole image as well as competitive power raising for single product. Therefore, this research wishes to examine some instances for the future competitive product development at the estimation of environmental friendliness using LCA techniques and more theoretical considerations of the LCA techniques that can dominate corporation's fate.

  • The world has been rapidly restructured in an agenda of national security from center of military strength to that of economic strength since the post cold-war era China military leadership-division carried out RMA through learning of a lesson from Gulf war in 1990 -1991 and Iraq war in 2003, thus the leadership-division made an attempt to convert the military system to a technical intensive system. The principle based on RMA of China military is (National defense strategy) drafted by the central military committee 1985 and (Four modernization general principles) 1978. China has introduced Russian high-technological arms and equipment in order to build up the military arms greatly thanks to an economical development, and they take pragmatism line as chinese socialism with their strategy to make secure a position as military powers such as they successfully launched a manned spacecraft and are building an air-craft carrie and soon. USA has a theory of dichotomy whether a country is a cooperator for USA, or not. and also enemy or friend since 9.11terror, thus USA is different from their direction of police. This is because USA stands a position as the superpower of the supremacy hegemony of the world. We must be carefully aware that USA considers as important area for Middle east, West south Asia, Central Asia and Northwest Asia to meet the demands of 2lcentury. Accordingly, the focus of USA's military strategy will be probably concentrated at the above mentioned four areas. On the other hand, USA enjoys such a superpower position due to collapse of USSR which was the past main enemy since the post cold war era. We could give an conclusive example as fact that USA has recurred to unilateralism But USA carry on the military operations to the terror groups at global around by converting thje military strike strategy to pre-emptive strike strategy since9.11 terror, 2001. USA seeks for transformation to the mobile military forces with light-quantity oriented in order to carry on such the military operations and makes progress GPR, And the USA forces in Korea makes progress a military renovation as part of such a military strategy. On the other hand, USA promotes the measures of choose for the countries standing at the crossroads of strategy and carries forward a main scheme of provision for four priority aims that the leaders of a hostile country and mis-country shall be prohibited from use and obtainment of weapons of mass destruction. Accordingly, this treatise found out a significant meaning to have an effect on the national security in the korean peninsula.

  • The purpose of this study is to present theoretical and policy implications based on the results of the empirical analysis of job stress in consideration of insufficient prior research on the level of job stress by public officials in charge of social welfare and public officials in general administration. For this purpose, social welfare and general administrative positions working at the City Hall of G Metropolitan City and five autonomous districts(including the Dong community service center) were selected as subjects for research. The data analysis used the SPSS statistical program to obtain technical statistics based on the average of the lower variables of the job stress. According to the analysis, there is a difference in the subjective perception level of public officials in charge of social welfare and public officials in general administration in both internal factors of job, such as job demands and job autonomy and external factors of job, such as job insecurity, organizational system, conflict of relations, inadequate compensation, and job culture. Based on this, it presented policy measures that require the granting of self-esteem of public officials in charge of social welfare, improvement of their duties, and adjustment of their workload to an appropriate level.

  • As the development of the 4th industrial revolution in the maritime industry has accelerated, the technical development and progress of maritime autonomous surface ship(MASS), and the development of international regulations have been accelerated. In particular, the IMO Maritime Safety Committee(MSC) has established a road-map for the development of the non-mandatory goal-based MASS instrument(MASS Code) and started developing a non-mandatory MASS Code at MSC 105th meeting. Many countries are actively participating in the Correspondence Group on the development of MASS Code, and the development of detailed requirements for MASS functions in the MASS Code is underway. Especially, the concept of "Mode of Operation" for MASS functions was mentioned in the Correspondence Group for the first time, and it is expected that discussions on these modes will be conducted from the IMO MASS JWG meeting to held in April 2023. The concept of "Mode of Operation" will be useful in explaining MASS and MASS functions and will be discussed continually for the development of MASS Code. This paper reviews the contents of the IMCA M 220 document, which provides guidelines on operating modes, to conduct research on the benchmark for setting the operating modes of MASS.
