IBM developed the MPI-IO, we call it MPI-2, on the General Parallel File System. We designed and implemented various Matrix Multiplication Benchmarks to evaluate its performances. The MPI-IO on the General Parallel File System shows four kinds of data access methods : the non-collective and blocking, the collective and blocking, the non-collective and non-blocking, and the split collective operation. In this paper, we propose benchmarks to measure the IO time and the computation time for the data access methods. We describe not only its implementation but also the performance evaluation results.

지역예술단체는 공연, 전시, 공모전, 축제 등 지역 내 다양한 행사를 주관하고 지역예술가의 정보 공유의 장, 신진예술가 발굴 및 지원 등 지역의 문화예술활동을 주도하며 오랫동안 지역 사회의 예술문화 발전에 큰 공헌을 하고 있다. 지역예술단체 기록은 과거와 현재의 지역문화예술의 수준과 가치를 보여주는 역사적인 의미를 지닌 기록이기 때문에 체계적인 관리가 필요하다. 또한 다양한 프로젝트를 진행하면서 생산된 지역예술단체의 기록은 이용자의 관심과 요구가 높기 때문에 이를 효과적으로 보여줄 수 있는 전시 서비스가 필요하다. 이에 본 연구는 공개소프트웨어인 CollectiveAccess를 기반으로 지역예술단체 디지털 아트 아카이브를 구축하여 지역예술단체 기록을 체계적으로 관리하며 전시 서비스할 수 있는 방안을 제시하고자 한다.

In order to overcome social exclusion and to integrate social housing, it is necessary to plan a communal space in urban collective housing so that residents can have belonging sense and community consciousness. In this study, it is necessary to consider the linkage between social integration and residential space, and to derive the characteristics of planning the collective housing for social integration. We analyzed the planning characteristics of MVRDV's communal spaces of collective housing and suggested a method of planning communal spaces of urban collective housing for social integration. Urban density is an important tool and background for MVRDV's design methodology. For this reason, MVRDV's collective housing is selected as a case study in this study. As a result of case analysis, openness and connection characteristics should be considered by using various devices such as glass exterior, balcony, and void in planning the communal space in urban collective housing for social integration. However, since it has appeared in many cases, it can be criticized that the application of this is merely a logic. In other words, it is possible to suggest that we should actively introduce less accessible access. This problem should be solved through more case studies.

The study aims to analyze the adaptation strategies and resilience of tobacco farmers to face unfavorable trading system. The research method refers to a qualitative approach with phenomenological models and case studies. The findings revealed tobacco farmers in Jember developed various adaptation strategies and resilience through farmer group organizations, partnerships, self-capacity building and access to financial institutions based on economic, social, cultural, and experience values from various sources and interactions among fellow tobacco farmers. The tobacco trading system, which is left to the market mechanism, results in low bargaining power of farmers, this encourages tobacco farmers to develop various adaptation and survival strategies, namely through collective activities of farmer groups, partnerships and self-development and access to financial institutions. Dealing with the unfavorable tobacco trading system, tobacco farmers do not switch to other commodity farming but adapt and make Jember a center for tobacco production in East Java and Indonesia. From this findings, it suggests to the government as the regulator does not only provide subsidies for tobacco farmers, but also must provide various technical assistance to increase the ability of tobacco farmers. More importantly, regulations must be made benefit tobacco farmers other than corporations so that equality can be enjoyed by tobacco economy players.

In the era of the pandemic, the importance of a wireless LAN environment has become increasingly important, especially as the era of smart working and non-face-to-face education has become a universal and daily routine. Smartphones, tablets, laptops, PCs, smart watches, and wearable devices, collective referred to as wireless terminals, can be accessed anytime and anywhere through the internet, allowing for consistent and constant access to offices, factories, warehouses, shopping malls, railways, hotels, hospitals, schools, logistics centers, airports, exhibition halls, etc. This sort of access is currently being used in roads, parks, traditional markets, and ports. Since the release of the IEEE 802.11 Legacy Standard in 1997, Wi-Fi technology has been continuously supplemented and revised, and the standard has been continuously developed. In the era of smart working, the importance of efficient wireless deployment and scientific design has become more important. The importance of wireless in the smart factory, in the metaverse era, in the era of pursuing work and life that transcend time and space by using AR, VR, MR, and XR, it is more urgent to solve the shadow area of Wi-Fi. Through this study, we intend to verify the wireless failure problem of the xr training center and suggest improvement measures.

Recently the international transfer pricing became the most popular topic in accounting of the research as well as of the practice. Modern corporations have been experiencing a lot of changes in managerial control technique as their scale and scope of activities grows and the environment in which they operate changes rapidly. If there are internal transactions in a decentralized firm, the necessity of coordination among the divisions is inevitable. Transfer pricing in a decentalized company provides an excellent example of the coordinating role of information. One of the most important reason for a form to have a decentalized structure is the improved decision making at the lower level due to better access to information. International transfer pricing is not merely a problem of pricing but coordination of transfers and other collective or individual actions to derive rents from intergration. Such coordination can be achived through the performance evaluation scheme which is partly based upon transfer price.

In health care, the process of resource allocation becomes a controversial process of rationing, as scarce resources are allocated between the numerous health care interventions. Especially for the last few years, decisions to define and expand the benefit package of National Health Insurance have always become the object of fierce criticism. It is partly because we have not reached a collective agreement as to what the most important criteria for spending priorities are. This paper considers the procedures and the principles which could be used to determine rationing in health care, and emphasizes the need to have explicit principles which determine patient access to care and to have an evidence base to inform rationing decisions. Also, the need to set up a public committee is suggested to take rationing decisions on behalf of government and NHS and to present them as evidence-based decisions.

Electronic environment affects archival community to a great extent. It redefines virtually every stage of archival management form creation to current and semi-current use, to appraisal, and to preservation of records. Faced with the problems caused by ever increasing electronic records, the community is forced to reconsider traditional concepts, approaches, methodologies, even the basic paradigm embedded in archival theory and practice. The present paper discusses the need to reexamine principles and techniques of archival management in the light of digital environment. It also urges archives and archival institutions, the archival profession, or the archival community at large, to participate in this critical enterprise. Success in this endeavor will, eventually, pave the road toward creating, organizing, providing access to, preserving reliably and authentically electronic records and designing proper system for the societal collective memory in recorded digital information.

다양한 개발 환경의 이질성을 수용하고 유연한 유지보수가 가능한 마이크로서비스 아키텍처는 급변하는 요구사항에 맞춰 서비스를 관리할 수 있는 비즈니스 민첩성을 확보할 수 있다. 서비스 내부의 마이크로서비스 간 통신이 잦은 MSA의 특성상 보안 측면에서 기존에 사용되어온 경계 보안은 충분하지 않으며 Zerotrust 시스템이 필요하다. 더불어 마이크로서비스의 규모가 커질수록 각 서비스의 API 포맷 형식에 따른 접근제어 정책 정의가 요구되며 서비스를 재배포하는 과정에서 불필요한 거버넌스 오버헤드가 발생하는 등 정책 관리에 어려움이 가중된다. 본 논문에서는 Zerotrust 보안을 적용한 환경에서 일괄적이고 유연한 정책 관리를 위해 OPA(Open Policy Agent)라는 범용 정책 엔진으로 접근제어의 결정과 시행을 분리하여 중앙 집중식으로 정책을 관리하는 마이크로서비스 아키텍처를 제안한다.
