TRUTEC building, which is located at DMC B block is zone, is just one the office building in Soeul. TRUTEC building is designed by Barkow Leibinger Architeken in Germany, has 5 stories under and 12 stories above and has been finished with the unique three dimensional curtain wall unit. Big trial to make unique elevation succeeded as getting rid of the typical plain curtain wall unit. In addition, aluminum bars are treated by the latest CNC machine in order to achieve 3D section. Construction of curtain wall is highly focused from the moment of contract to keep the schedule because the contract period is 18 months. Regular design meeting and technical meeting between stakeholders including construction manager, designer, engineer, consultant and so on have been held during the construction to minimize the risks from the unique elevation and trial. Step by step mock-up test (design mock-up and visual mock-up on site) has been performed before functional mock-up test.

Only small numbers of medium-sized manufacturers have adopted a production management system. They have difficulty maintaining production cost and progress management, because they have used the ways that win a contract, not mass production system like a big company. Also a small company has to change standard features of products whenever customers want, by means of non-standardization and small quantity production method. As a result, it has been very difficult for a small company to establish a proper production management system. So, this paper tried to make a study about increasing production management system, using QR codes in a small-sized manufacturer with the ways that win a contract, based on real application case.

In this paper, we propose a API Gateway technique for the expansion of human resource management module, one of the ERP functions. The institution has introduced ERP (Enterprise Resource Planning) based on its efforts to transform all human and physical resources into business competitiveness and its response to the digital knowledge informatization environment, and listed it as multiple success factors. Human resource management is one of the factors that have been dealt with. However, ERP's Human Resources Management Module remains in the role of functional personnel management. How to utilize human resources begins with navigating and recognizing human resources. The proposed API Gateway technique leverages blockchain networks to design and implement APIs for human resource sharing and navigation, including the possibility of extending ERP's human resource management module. Secondly, it was designed and implemented using a smart contract that behaves like an API for preventing information forgery. The proposed method will not only be used as a tool that can actively utilize human resources, but will also be a complete resource for utilizing big data technology.

This study is to in-depth analysis of the copyright issues related to the library's e-book service, which is the cause of the recent conflict between the publishing industry and the library industry. To this end, the purpose and outline of the copyright system were briefly summarized. Then, the jurisprudence of the Copyright Act applied to the borrowing of paper books and e-books was analyzed, and the position of the publisher's association and the library industry were reviewed together. In addition, problems of the current copyright act related to e-book services were diagnosed and directions for improvement were sought. Unlike in the case of paper books, first sale doctrine does not apply to e-book borrowing, so the library cannot acquire the right to service just by purchasing e-books. Based on the contract signed with the distributor in the process of purchasing the e-book, the library acquires the right to service the e-book. However, if the validity period of the exclusive publication right expires, the contract itself becomes invalid, which can cause serious problems in the stability of library services and preservation of resources. In order to solve this problem, it is suggested that the first sale doctrine needs to be extended to digital works.

E-book markets are currently moving through a period of disequilibrium as new pricing structures (i.e., flat-fee subscriptions) are rapidly embraced by major vendors. On the basis of a novel dataset, we investigate how the availability of "all-you-can-read" pricing programs influences consumers' tariff choice and contract renewal behaviors. Consistent with the rational choice framework, the findings suggest that most e-book consumers significantly gain from subscription-based tariffs. Power readers prefer flat-fee subscriptions, and those that have economically benefited renew their subscription. However, we also find some other intriguing results. Among the three subscription designs examined, the 1-week plan affords consumers more economic benefits than do 1-day or 1-month programs. Finally, iOS users are more inclined to select subscription models than are Android users because of the absence of in-app purchase functionalities for the former. The unavailability of in-app purchase affects tariff choices and transaction patterns as it increases transaction costs.

Recently the leak of personal information from in-house and contract-managed companies has been continually increasing, which leads a regular observation on outsourcing companies that perform the personal information management system to prevent dangers from the leakage, stolen and loss of personal information. However, analyzing many numbers of computers in limited time has found few difficulties in some circumstances-such as outsourcing companies that own computers that have personal information system or task continuities that being related to company's profits. For the reason, it is necessary to select an object of examination through identifying a high-risk of personal data leak. In this paper, this study will formulate a proposal for the selection of high-risk subjects, which is based on the user interface, by digital forensic. The study designs the integrated analysis tool and demonstrates the effects of the tool through the test results.

As the cloud services, the underlying technology of the digital convergence environment, have been widely adopted in the business, personal information protection has been recognized as one of the major issues to resolve. When cloud services are used to process the personal information, the personal information protection law speculates the establishment of a contract or service level agreement(SLA). This research presents 7 privacy indicators and 13 metrics which can be included in cloud SLA, based on the analysis of related regulation and standards and the SMART(Specific, Measurable, Action-oriented, Relevant and Timely) model. The proposed indicators are examined using the Focus Group Interview method in terms of materiality and feasibility. The results show that all the proposed indicators are meaningful and useful.

NFT is literally a 'non-fungible token', a digital file that records specific virtual assets on a blockchain. Events such as ownership of the asset and transaction history are recorded on the blockchain through the token transaction, so counterfeiting and falsification are impossible. Therefore, NFT is used as a tool that can uniquely represent a specific virtual asset. The main purpose of this paper is to examine the characteristics of NFT from a records management point of view and to find ways to use them, and focuses on digital records that have the characteristics of assets as digital works. For this purpose, we first examine the basic concept of NFT and the principle of ownership and proof of value as an asset for digital works. In addition, it was confirmed how the advantages of NFT were applied through NFT use cases in various fields, and in particular, areas related to audio-visual records such as art, music, sports, and fashion were focused on. Furthermore, by comparing the characteristics of digital records with those of NFT, factors applicable to electronic records were identified. Finally, the types of digital records that are expected to be effective in the application of NFT were identified, and the possibility of their use and discussion points for introduction in records management are presented.

The Housing Lease Protection Act was enacted from March 5, 1981 as Law No. 3379 to guarantee the stability of residential life and legal status. After then, there were many problems, but through several times revision, it had improved insufficient part. However, in order to give guarantees actually the position strengthen for homeless poor people many issues still need to be solved and it has been raised. Along the way, with the introduction of the tenant renewal claims, in February 14, 2015, the National Assembly planned to discuss current issues by operating the Special Committee for housing welfare of ordinary people in the extra session. In the current, however, the conflict of the pros and cons is shown clearly. Meanwhile, because the contract renewal claim of tenant was not guaranteed, if the minimum duration of the lease will be lapsed, contract renewal is dependent on the intention of landlord. Thus, the residential stability of homeless poor could become unstable. Therefore, in this paper, to stabilize the residential living for tenants who are in poor status, analyze our term of existence regulation and through the compared to the national legislation about the term of existence, it will try to propose the specific legislative approach to the problem.

Internet shopping mall business has taken its place as a major form of e-commerce and is evolving constantly. At the same time, disputes of various kinds are also arising in proportion to the evolution. A typical example is when a consumer purchased a product from an internet shopping mall and the seller wants to cancel or withdraw the sales contract saying that he miswrote the price or other important information when posting the product on the internet. It's about the error on the seller's part. Civil Law Chapter 109, legal principles on errors, appears to assume the case of natural declaration of intention. It was observed that legal principles on errors defined by the Civil Law are also applied in internet shopping malls, where declaration of intention is made electronically. In transactions involving internet shopping malls, where the seller's indication and advertisement constitutes an inducement to offer, the seller may cancel a contract concluded by the consumer's offer and the seller's acceptance if the seller finds errors on his part, and adequacy of the cancellation should be judged depending on specific cases. That is, the judgment of the important ground that comprises prerequisites for cancellation and presence of negligence may depend on how much difference there is between the normal price and the posted price on a specific case. Also, considering the cases where negligence was not perceived on the seller's miswriting of the price, the seller may cancel the transaction in a similar situation.
