'건축실무에서의 전문성 국제기준권고안에 관한 협정' 즉, 건축사자격의 국가간 상호인정에 관한 국제표준안(세부내용은 본지 9903, 9904월호 참조)이 지난달 중국 베이징에서 개최된 국제건축사연맹(UIA) 대회 및 총회에서 정식 채택됐다. 특히 이번 UIA총회에서 주요 의제로 다루어진 '국제기준권고안' 가운데 '건축사의 기본요건'에 관한 부분은 지난 1985년 유럽공동체(EC, 현 유럽연합 EU)에서 채택된 내용을 토대로한 PPC(Professional Practice Committee)의 보고서 내용 그대로 채택됐고, 이러한 기본요건을 갖추는데 필요한 건축교육으로서, 최소 5년이상의 인가된 대학의 인증된 전일제 건축프로그램을 이수할 것을 권장하고 있다. 이에 따라 우리나라도 교육기관의 교육과정에 대한 개편이 필요하게 된 것은 물론 지금껏 생소했던 교육인증프로그램 등을 서둘러 마련하지 않으면 안되게 되었다. UIA베이징대회를 다녀온 본협회 국제위원들의 참가보고를 통해 이번 제21차 총회의 주요 의결내용과 전반적인 대회 분위기 등을 살펴본다.

This research refers to the importance of health care in relation to the establishment of health care facilities and health care facilities in the rapidly changing health care environment, and the influence of health care in relation to the customer's satisfaction with health care. Orthographic analysis First, a hypothesis was adopted that the attractiveness of building materials will affect the positive (+) impact of the customer's satisfaction. Second, the hypothesis that the transport infrastructure will have a significant impact on the customer's satisfaction with the customer's satisfaction has been denied. Third, the hypothesis that the building appeal will have a significant effect on the health of the medical industry is adopted. Fourth, the hypothesis that the transport infrastructure will have a significant impact on health care is adopted. Fifth, the hypothesis that medical integration will have a significant impact on the customer's satisfaction with the customer's satisfaction is adopted. Sixth, the hypothesis that the relationship between the building and the customer's satisfaction in relation to the relationship between the client and the client was found to be partly attributable to the fact that there was a partial role. The assumption that the relationship between the transport infrastructure and the customer's satisfaction in relation to the traffic infrastructure was established has been identified as a complete parameter. The results of this study could be applied to provide the basis for selecting the location for future health care facilities.

This study examines the importance of location and transportation in the operation of small- and medium-sized hospitals in the rapidly changing clinical environment. Approximately 350 persons were surveyed for approximately 40 days from July-August 2017, and responses were analyzed using SPSS and AMOS Statistical Package for 335 parts excluding 8 parts of 343.The main research results were as follows: First, a hypothesis was adopted that the attractiveness of building materials will positively affect customer satisfaction. Second, the hypothesis that transport infrastructure has a significant impact on customer satisfaction was rejected. Third, the hypothesis that the building appeal will positively affect the site was supported. Fourth, the hypothesis that transport infrastructure will have a significant impact on location marketability was supported. Fifth, the hypothesis that location marketability will significantly impact customer satisfaction was supported. Sixth, the hypothesis that the relationship between the site and customer satisfaction with the relationship between the client and the client is explained is partly attributable to the fact that there is a partial function. The assumption that the relationship between traffic infrastructure and customer satisfaction was confirmed. The hypothesis that the relationship between traffic infrastructure and customer satisfaction was supported. This research focuses on small- and medium-sized hospitals located in Seoul, which does not include the recognition of patients' awareness of the location and transportation of small- and medium-sized hospitals. Moreover, this study has the limitation in analyzing patient satisfaction, rather than the objective data of the financial management performance of the hospital. The results of this study could provide the basis for selecting the future locations of health care facilities.

This study is an attempt to identify factors determining the success of international standardization and understand the relationship between the factors, such as government-driven standardization activities. Six factors were identified through factor analysis; namely, 'Direct government support', 'Indirect government support', 'Utilization of standardization bodies', 'Standardization strategy', 'Attainment of a dominant market power', and 'Adoption as an international standard.' The results showed that firstly, support from the government, whether direct or indirect, had no direct effect on the outcome of international standardization efforts, but produced an indirect influence on it through mediating factors such as the attainment of a dominant market power. Secondly, the attainment of a dominant market power proved to be the most important success factor of international standardization, suggesting that the government must direct its efforts to help boost the market power of target standards through measures like promoting a timely market entry and the development of high-quality standards, in a manner to induce market satisfaction, increasing lock-in effects and building a quasi-vertical integration system. Thirdly, direct support from the government holds the key to the success of international standardization with de jure standardization bodies, while the strategic use of standardization bodies appears the most important for the positive outcome of standardization concerning de facto standardization bodies.

The purpose of this study was to examine the impact of the uncertainty of competitive environments on the commitment of manufacturing firms with distribution firms, their trust and long-term orientation in Korea, the United States and Japan. This study is of great significance in that it attempted to make a comparative analysis of the uncertainty of competitive environments among the three nations by selecting subjects not only from Korea but from the United States and Japan. A survey was conducted on the selected manufacturing firms, and the data from 105 Korean firms, 103 American companies and 83 Japanese firms were gathered. A structural equation was utilized to analyze the collected data. The findings of the study were as follows: Hypothesis 1 was rejected in Korea and Japan and was accepted in the United States. Hypothesis 2 was accepted in Korea yet not in the United States and Japan. Hypothesis 3 was accepted in all the nations. Hypothesis 4 was rejected in Korea and the United States and was accepted in Japan. Hypothesis 5 was accepted in all the nations, and Hypothesis 6 was accepted in every nation as well. In the future, the commitment, trust and long-term orientation of manufacturing and distribution firms should be investigated from a mutual perspective, and additional data should be obtained by selecting more subjects. As for environmental uncertainty, the uncertainty of distribution environments as well as competitive environments should equally be investigated by making a comparative analysis.

In an academic ecosystem evolving into open science, open peer review is gaining attention as a way to enhance transparency and openness in scholarly communication. This study examines the adoption of open peer review components in 118 open access journals that have implemented open peer review, and their characteristics by publisher type, country/continent, language, and discipline. Open peer review has been implemented in a variety of ways, including making review reports or pre-prints publicly available or disclosing the identities of authors and reviewers to each other. We also found differences in the components adopted across disciplines. It appears that commercial publishers, which account for a large proportion of publisher types, have generally adopted it, and it is mainly published in English in European countries. By discipline, we find more open peer review in the medical and natural sciences, which traditionally aim for open scholarly communication and fewer journals in the multidisciplinary and humanities. This provides insights into the adoption of open peer review by journals, as well as a better understanding of the characteristics of the academic community in terms of their adoption of open peer review.
