  • The National Housing Bond Information Relay System is a representative financial information relay system in which institutions are connected with center system. A centralized structure is expensive to construct and operate center, and there is a problem that all networks are disconnected when a failure occurs in the center system. In this paper, we propose the national housing bond information relay system model based on Blockchain technology that can process information safely and efficiently. The proposed model constructs a Blockchain network so that each institution that processes the national housing bond information can transmit information safely, and each institution manages the same distributed ledge by a smart contract. The proposed model can reduce the cost because it can process complicated national housing bond transaction information without a relay center, and a network usage and disk usage decreased by 1.7% and 8.53%.

  • In order to perform a successful outsourcing, we needs the SLA through improving the quality of IT services. In particular SLA metrics and evaluation criteria is an important factor as to substitute the IT viability of the company to promote IT Outsourcing. SLA metrics consist of technical, managerial, user perspective items, and has been managed to aim to provide reliable and continuous quality improvement of IT services. This study focuses on the HW availability metrics of SLA indicators of IT outsourcing. We propose the Infra availability criteria for the HW configuration level to meet the SLA contract and evaluation. We offer the Infra configuration standards of SLA contract, and propose criteria to determine the suitability of the target levels in IT operations audit environment. The proposed model was verified the necessity and effectiveness of the Infra configuration standards and operation audit check items through the surveys of experts and users.

  • Korea government has established clear cost estimation standard based on a survey of e-learning contents development cost and presented 'e-Learning Contents Development Cost Estimation Guidelines' that reflect the characteristics of the e-learning industry. However, if there is no institutional support, this guideline and system fails to achieve the purposes and objectives. And it is likely to be facing a dead document. Therefore, the policy foundation is required. This study suggested the following policy; stepwise activation of cost estimation standard, enact announcement and periodically adjustment of cost estimation standard, installation and operation of cost estimation standard operational committee, conjunction with the e-learning industry survey, cultural diffusion of co-owned copyright, systematic monitoring of the e-learning contents development process, research on activating policy of cost estimation standard, conjunction with the standard contract for enhancing policy effectiveness.

  • Broadcaster and production studio inevitably take the risk in Korea because the outsourced drama is contracted before produced. However, it is important for both parties to share risk and reward. This study seeks to assess the fairness of the copyright contract between broadcaster and production studio by examining whether they both have the balanced risk and reward structure. For the study, revenue and cost elements with their amounts are identified, which come from TV commercials, oversea sales, the secondary windows, sponsorship, and product placement. Next, the revenue and COGS (Cost of goods sold) of broadcaster and studio are estimated for both cases of when drama becomes successful or not. The analysis reveals that the current copyright agreement allows broadcaster hold low risk but high reward whilst production studio takes high risk low reward. However, the result doesn't imply that government intervention is justified because demand and supply determine the negotiation power in a free economy.

  • This paper proposes a blockchain system to share Wireless Local Area Network (WLAN) that recently suffers from mutual interference among increasing devices using unlicensed bands. Blockchain technology can induce cooperation from users by incentivizing them with cryptocurrency like shown in Bitcoin example. In this paper, we describe Blockchain based access mechanism in WLAN instead of conventional authentication based access. Here, users can access any WLAN access point by paying through smart contract while they also receive payment from others. In order to support real-time transaction, we apply proof-of-authority that is realized by Byzantine fault tolerant protocol instead of well-known proof-of-work that requires huge computing power and delay.

  • This study examined the effects of the firm characteristics of the manufacturing industry on the female employment ratio. Three hypotheses regarding female employment ratio, were tested for 5,729 firms that could use financial data among the firms listed on the KOSPI from 2011 to 2019, in terms firm size, listing period, and foreign ownership. Follwing the analyses, three hypotheses were mostly adopted. It was found that as the size firm and foreign ownership ratio increased, the female employment ratio increased in the number of regular and permanent contract employees, fixed-term employees, and total employees. As for the listing period, the higher the value, the lower the female employment ratio in the number of regular and permanent contract employees, fixed-term employees, and total employees. These research results may be used as basic data for gender equal employment policies such as Affirmative Atcion for Gender Equal Employment.

  • Building Information Modeling (BIM) has the great possibility of transforming the AEC industry. BIM will require increased information exchange and mutual collaboration between all stakeholders. BIM implementation and such increased collaboration can affect legal issues and contract provisions. And some legal issues accompanying BIM Implementation will be raised while a large change also comes in responsibility and role between all stakeholders. However, current standard agreement system is based on fragmented agreement between the architect and the owner, and between the owner and the contractor. Another legal obstacles and considerations associated with BIM implementation will be arose from BlM technology and use of BIM. AEC professionals in Korea have long utilized the standard agreement forms as well and look forward complementation of current standard agreement for BlM implementation. Such complement direction for the standard agreement will be examined by investigating the legal issues and overview comparison between AlA E202 and ConsensusDOCS 301.

  • Blockchain technology has paved the way for the rise of non-fungible tokens(NFTs) in recent years. NFTs enable the unique ownership of digital assets and harness the power of blockchain's transparency and decentralization. However, existing NFT platforms often pose barriers to entry for the public due to their technical complexity and high issuance costs. To address the problem, this paper proposes a user-friendly NFT platform with a simplified issuance process. A home page is created to allow easy NFT issuance for anyone. These advancements are expected to foster the growth of the NFT market and facilitate the development of new business models.

  • Present study aims to describe who are the non-regular female workers in South Korea. The dominant form of employment of Korean female non-regular workers is characterized by instable contract, low wage, long-time work and exclusion from the state and occupational welfare. Also, non-regular female workers are not homeogenous but there are various groups of women among female non-regular workers including young part-time workers, high educational middle class contract professionals, particular contract workers such as home-schooling teachers. However, it would worth noting that over 40s, low-educational, low income, breadwinning women who are working in sales, service, and simple handy job are most likely to become non-regular female workers in South Korea. Those women are the major group among non-regular female workers. The public assistance (in cash) for non-regular workers are necessarily needed for them at this point in South Korea.
