Recently, as Information System projects tend to be more complex, the importance of Information System Audit increases. In the same context, the need for the resident IS Audit also increases, which is supposed to deal with the possible risks and urgent issues by providing the appropriate support and timely coordination during IS project. Basically, for the effective IS Audit, the IS audit team members should be able to understand such a business context as work characteristics, business knowledge, goals, and culture of the organization. The audit team members should also be able to share the various knowledge of Information Technology and audit procedure with the owner of the project. Especially, for the resident audit, it is more important to fill the gaps in expertise between project owner and audit team. However, any studies on the need of common knowledge base (knowledge complementarities) in the IS audit have not been done so far. The purpose of this study is to analyze whether the knowledge complementarity based on inter-organizational communication between the project owner and audit team members makes an effect on the fidelity and performance of IS audit. In order to do this, the relationship among inter-organizational communication and knowledge complementarity, the fidelity of IS audit service, and performance of IS audit has been analyzed, using Structural Equation Model. The result shows that all the relationship is significant, which means that knowledge complementarity between the two different interest groups should be an effective factor on the fidelity and performance of IS audit. This result implies that, for better quality of IS Audit service, how to acquire the knowledge complementarity between the project owner and Audit team should be considered seriously as well as systematically in the process of IS Audit.

This research examines the spatial development of rural industrial estates (Nong-gong Jigu) in Chonbuk province and gives insight into the strategies for economic development in the entire region. Selected location factors which are likely to pull new investment into the estates are examined by using questionnaires. Few loction factors except nonlocal factors can be found in explaining why location choices are made. The irrelevance of the analysis based on location factors suggests that an alternative approach should analyze changes in the spatial development of the rural industrial estates. Such an alternative is to understand the dynamics of the spatial organization of production by focusing on characteistics of plant closing in the rural industrial estates. To take into account of the characteristics of plant closing we provide the hypothesized relationships between employment size, organizational structure, inter and intra industrial linkage, characteristics of production processes, and availability of local labor market and the likelihood of closing. A logit model is then made to identify the selected factors which might influence the probability of plant closing. The results from the logit analysis and their implications suggest that the policy should be more concerned with the characteristics of firms, such as size and ownership, as well as of the local labor markets. Given that the Chonbuk region has experienced rapid population decline, together with its poor industrial base, it seems that the success of the policy in the declined rural areas in less certain.

Concurrent Engineering is one of the methods which are used for the rapid product development. One of the important features in Concurrent Egineering is that the development process is to be parallel and the organization should be cross-functional. In order that the process be parallel and that the organization be cross-functional, an integrated information system such as PDM (Product Data Management) is required. Although the integrated data base is constructed, it could be meaningless if the application softwares were not inter-operable. This study shows an example of intergrated information system from three-dimensional product design to mold design and tooling for the development of Deflection Yoke(DY) which is one of the important parts of Cathode Ray Tube(CRT). A three-dimensional product design software, which is based on a commercial code, has been developed by ourselves. Selective Laser Sintering(SLS), which is one of the rapid prototyping techniques, has been used in this study. Mold design has been done by the three-dimensional way. A newly developed method of mold tooling, which is called Quick Die Manufacturing(QDM), has been introduced.

Mangroves are important coastal ecosystems and are located at the inter-tidal zones of tropical and sub-tropical belts. The global mangrove forests are declining dramatically because of the conversion of forests to shrimp farming, over-exploitation, pollution and freshwater diversion. The Bangladesh Forest Department initiated mangrove afforestation throughout the coastal belts of Bangladesh in 1966 to provide better protection for the coastal communities. Up to 1990, 120,000 ha of mangroves had been planted and it is one of the largest coastal afforestaton programs in the world. The objective of this study is to exploit the spatial extent of mangrove plantation and their dynamics of changes over the last two decades using multispectral Landsat imagery. The study area covers the coastal areas of Bangladesh that is extended over the eastern part of Sundarbans up to Teknaf, the southern tip of mainland Bangladesh. Mangrove plantations were interpreted visually on computer screen and interactive delineation of forest boundary was done. The mangrove plantation area has been estimated as 32,725, 47,636 and 43,166 ha for the year of 1989, 2000 and 2010, respectively. Mangrove deforestation by human activity has increased almost six times in the recent decade in comparison to the previous one. The mangrove forest loss due to coastal erosion has slightly declined in the 2000s. Mangroves have been lost primarily because of agricultural expansion. The result of this investigation will be helpful to understand the dynamics of mangrove plantation and the main drivers of changes in this coastal ecosystem.

Aires Mateus Architects is one of the most well-known Portuguese architects after $\acute{A}lvaro$ Siza and Eduardo Souto de Moura. The studio shows clear design methods in which the relationship between solid mass and void space are creatively inter-connected. Subtractive transformation of form is the fundamental aspect of this relationship. Most of Aires Mateus' projects were designed based on the subtractive method. Although subtraction can be seen as architectural formal presentation, in Aires Mateus' cases, there are deeper logics, strategies, and meanings. Not only to create a form, subtractive method has been flexibly used to organize and compose different programs and spatial atmosphere. To examine this hidden dimension of Aires Mateus' unique design process, 5 case projects were selected and analyzed in detail based on program, light & visual-perception, and site's placeness. From the case study results, it is found that there are much deeper role of subtraction: relationship between solid-void are constantly changing to generate serviced and servant spaces, there are central spaces that are contrast against the complexity of exterior forms, aiming to build an archetypal form that transcends ever-changing time, ambivalent balance between universality and peculiarity in the genealogy of contemporary architecture. The study concluded that the unique characteristics of subtraction method as design organization have various possibilities that can apply on other architectural and interior projects which would have similar ideas and circumstances.

Business-to-Business electronic commerce websites are a common form of inter-organizational systems that span organizational boundaries and enables organizations to exchange information in a seamless fashion. To reap the desired benefits it is important that the website be used in the intended manner. The level and extent of use of a business-to-business website depends partly on the inclination to use the website by the users in the primary organization and in the user organizations independently and the combined inclination of the organizations together. This combined inclination is referred to as the System Inclination, with dominance playing a key role. Each organization has certain characteristics of its own and may differ significantly in their inclination to use. It is important to analyze the factors that determine this inclination to use, so that organizations can adopt appropriate management mechanisms to control it. This paper proposes a framework to explain the organizational factors and their influence on the inclination to use a website, based on study of four Indian buyer-supplier dyads. Inclination to use is found to be influenced by factors like top management support, website characteristics, adequate support mechanisms, user group orientation towards electronic commerce and basic IT drive among the employees, at both the primary and user organizations.

The purpose of this paper is to make research on the settlement mechanism of the commercial disputes between the South and the North of Korea. Also, this paper is to make research on the south-north Korea's cooperative tasks to promote the disputes settlement, including the operation and management of the South-North Arbitration Commission as well as the enactment of the South-North Arbitration Rules. To realize the spirit of the South-North Joint Declaration of June 15, 2000, the Authorities concerned of the South and the North of Korea have reached an agreement titled 'Agreement on Settlement Procedure of Commercial Disputes' on December of the same year. As the follow-up measures of the said Agreement, the South-North Authorities have signed an another agreement called 'Agreement on Organization and Administration of the South-North Arbitration Commission' on October, 2003, which is becoming vital importance for settlement of the commercial disputes between south and north Korea including the Gaeseong Industrial Complex. Gaeseong, a city surrounded by the North Korean military and a symbol of inter-Korean tensions, is now turning into a peace zone where thousands of North and South Koreans are working side by side. The Gaeseong Industrial Complex project, driven by the logic and economic necessity of cooperation, has been steadily moving forward since the North designated it as a special economic zone and has enacted related laws and regulations for its development. Under the situation, the matter of primary concern is how to organize and conduct the Arbitration Commission for the prompt and effective settlement of the south-north commercial disputes. First of all, the South-North Authorities should recognize that the availability of prompt, effective and economical means of dispute resolution such as arbitration and mediation to be made by the Arbitration Commission would promote the orderly growth and encouragement of the south-north trade and investment. In this connection, the Korean Commercial Arbitration Board(KCAB) should be designated as the arbitral institution of the south Korean side under the Agreement on Organization and Administration of the South-North Arbitration Commission. The KCAB is the only authorized arbitral organization in South Korea to settle all kinds of commercial disputes at home and abroad.

For examining Web3.0 video streaming (VS) platforms in terms of the decentralized technology, tokenization and decentralized autonomous organization (DAO), we look at four platforms like DLive, DTube, Livepeer, and Theta Network (Theta). As a result, DLive which firstly partnered with Medianova for CDN and with Theta for peer to peer (P2P) network and migrates to Tron blockchain (BC), receives no commission from what creators earn, gives rewards to viewers by measuring engagement, and incentivizes participation by allowing 20% of donation & fees for funding development, 5% to BitTorrent Token (BTT) stakeholders (among these 5%, 20% to partners, 80% to other BTT stakeholders). DTube on its own lower-layer BC, Avalon, offers InterPlanetary File System (IPFS), gives 90% of the created value to creators or curators, and try to empower the community. Livepeer on Ethereum BC offers decentralized CDN, P2P, gives Livepeer Token (LPT) as incentive for network participants, and delegators can stake their LPT to orchestrators doing good. Theta on its native BC pulls streams from peering caching nodes, creates P2P network, gives Theta utility token, TFUEL for caching or relay nodes contributors, and allows Theta governance token, THETA as staking token. We contribute to the categorization of Web3.0 VS platforms: DLive and DTube reduce the risk of platform censorship, promote the diverse content, and allow the community to lead to more user-friendly environments. On the other hand, Livepeer and Theta provide new methods to stream content, but they have some differences. Whereas Livepeer focuses on the transcoding layer, Theta concentrates both on the video application layer and content delivery layer. It means, Theta tries to deliver value to all participants by enhancing network quality, reducing CDN cost, and rewarding users in utility tokens for the storage and bandwidth they provide.
