At present, the importance of organizational effectiveness is highlighted even more as business environment enters into a new type of work setting, the smartwork environment. This new type of work environment could be significantly influential in promoting organizational effectiveness of office administrators who carry out atypical types of tasks in general and are exposed to emotional labor excessively. Organizational effectiveness of office administrators could also be controlled by their concerns at work, their personal values and the increasing demand for work-life balance. The main purpose of this research is to investigate how smartwork environment perceived by office administrators is related with organizational effectiveness. In addition, this research places the focus on how concerns and work-life balance moderate the relationship between smartwork environment and organizational effectiveness. The survey was conducted among 102 office administrators, and data were analyzed by moderated multiple regression analysis method. Job autonomy of smartwork environment showed positive effect on job satisfaction, organizational commitment, and innovative behavior. IT dependence of smartwork environment showed negative effect on job satisfaction and organizational commitment and positive effect innovative behavior. It was found that concerns with impact positively moderate the effects of job autonomy on job satisfaction and innovative behavior; concerns with self negatively moderate the effects of job autonomy on organizational commitment and innovative behavior. Also, it was found that work-life balance moderates the effects of job autonomy on organizational commitment and the effects of IT dependence on innovative behavior. The result of this research can be taken into consideration when a strategic human resource development plan is prepared for office administrators in smartwork environment.

In this study, we mainly inquired into structural reforms of the current legal system that could minimize the side effects and protect financial customers as the use of AI robo-advisor were increasing. First, regarding a specific reform, it is necessary to introduce and establish a rapid detection system for unusual transactions by the Robo-advisor management company, the strict liability of the management company, the management company's mandatory obligation to obtain indemnity insurance, and limited criminal penalties. Furthermore, it is necessary to establish a comprehensive basic law regarding AI. In this basic law, the promotion of the development of AI technology and the minimization of side effects should be dealt with in harmony with each other. Like the approach of this study, we hope that similarly detailed and practical discussions will be made on the AI era from various perspectives in the future.

This paper investigates the effects of technology collaboration between the main supplier and buyer on buyer's new product development under dynamic environment. Based on 428 Korean manufacturing firms, we conducted regression analysis. The technology collaboration between the main supplier and buyer is adopted as a independent variable and quality, cost and lead time performance of new product development projects are used as dependents variables. Environment dynamic is also used as a moderate variables. We found that the in general, technology collaboration is positively associated with the performance of buyers' new product development, but in the high degree of dynamic environment, technology collaboration is negatively associated with the performance of buyers' new product development unlike our expectation. Thus, we divide our sample into two groups; shipbuilding industry with the low degree of environment dynamic and electronic and IT device industry with the high degree of environment dynamic and conducted a post hoc analysis. As a result, in ship building industry, the technology collaboration is significant to improve NPD projects performance, while in electronic and IT device industry, the technology collaboration with a main supplier is not significant as well as coefficient is negative. In that, under the highly dynamic condition with the fast change of technology and products obsolescence the NPD collaboration with the main supplier does not works unlike a stable environment. This implies that the NPD attributes of buyer are different by their environmental factor and the fit between given environmental feature and the collaboration synergy is critical factor for improving the effect of NPD collaboration between supplier and buyer.

After Bitcoin was proposed by Satoshi Nakamoto in 2009, studies have been carried out to apply the Block Chain technology in various environment, which was applied as a distributed transaction of Bitcoin. Smart contracts, voting and proof of ownership of digital contents are typical applications of Block Chain. They used the feature that it is impossible to modify or delete once recorded facts. They also applied to prove relevant facts and to provide data integrity. The applied cases are mainly made in an environment where the data should or could be open to the public, and they have been proposed as solutions to solve the problems occurred in relations. This fact has led to the attention that Block Chain can be applied as a good alternative in similar circumstances. In this study, real estate market service was selected to expand the application range of Block Chain. Although there are about 250 applications and web services in total, the satisfaction is not high due to false offerings. Thus we propose a countermeasure against the problem by applying the Block Chain to the real estate market service, and investigate the research direction of the Block Chain in the future market.

기업의 매출이 증가하고 성장함에 따라 유통채널은 다양해진다. 일반적으로 기업은 직접채널과 중간 판매채널을 거치는 간접채널을 통해 고객에게 상품과 서비스를 제공하고 있다. 이 두 가지 채널 중 중간유통채널, 즉 파트너를 통해 거래하는 방식이 가장 높은 비중을 차 지하고 있으며 그 비중은 점점 더 확대되고 있는 추세이다. 그러나 고객에게 기업의 가치를 전달하는 파트너들은 기술의 변화와 혜택에서 상대적으로 소외되어 있는 경우가 많다. PRM 시스템은 파트너가 원하는 가치, 제품정보, 뉴스, 시장정보, 공동마케팅을 할 수 있는 기반 등을 마련하기 위해 필요하고, 기업도 파트너를 정확히 이해하기 위해 라이프 사이클 운영 및 분석기술이 필요하다. 이러한 시장의 변화로 인하여 유통기업의 PRM 시스템 도입의 필요성이 부각되고 있다. 본 논문에서는 유통기업에서 PRM 이 지니는 가치를 알아보고 유통기업 H 사의 PRM 시스템 구축과정과 시스템 구축이 기업에 창출한 성과에 대하여 이야기 하고자 한다.

Korea has been officially classified as a non Annex-I country under the Kyoto Protocol, however, international community is used to considering it as if it were an Annex-I country. Korea has been under great pressure from the international community, especially from the EU and the US, to get included as an Annex-I country or to accept a legally-binding emissions reduction target like other developed nations. Korean Government declared its national target of emissions reduction in 2020 before the Copenhagen meeting, and also pronounced "Low-Carbon Green-Growth" as a new national paradigm to drive the entire nation toward a low carbon society and develop a new growth momentum. The 'green Act', which was passed by the National Assembly in 2009, is a comprehensive and fundamental law providing legal grounds to all of the national policies and measures that are needed to transform the nation into a low-carbon society. Korean government announced to begin Carbon Emissions Trading from 2015, instead of the originally scheduled year of 2013, considering global trends and industrial competitiveness in a flexible manner. The Carbon Emission Trading would reduce carbon emissions by 30 percent from the expected 2020 level, or 4 percent below its emissions in 2005.

With transition to Knowledge society and introduction of information industry, there are many companies which have higher stock price than the suggested value from its financial information. To explain similar cases in capital markets, many researchers focus on non-financial information such as Web Traffic data or intangible assets such as intellectual property rights rather than traditional financial analysis. Besides, the relationships between financial and non-financial information with firm value are changed according to industry lifecycle. As Industry grows, financial information of company is more important for firm valuation in Capital market. We'd like to review the changes of relationships between financial information and firm valuation in Capital market especially for "Software", "Digital Contents", and "Internet" companies listed in Kosdaq market during 2000~2011. The result of data analysis shows the financial information gets more important after 2007. Inversely, it provides analytical bases that related industry gets mature. Also we show that intangible properties are more relevant to stock price of those technical based companies than others.

As the production of new and renewable energy such as solar and wind power has diversified, microgrid systems that can simultaneously produce and consume have been introduced. In general, a decrease in electricity prices through solar power is expected in summer, so producer protection is required. In this paper, we propose a transparent and safe gift power transaction system between users using blockchain in a microgrid environment. A futures is simply a contract in which the buyer is obligated to buy electricity or the seller is obliged to sell electricity at a fixed price and a predetermined futures price. This system proposes a futures trading algorithm that searches for futures prices and concludes power transactions with automated operations without user intervention by using a smart contract, a reliable executable code within the blockchain network. If a power producer thinks that the price during the peak production period is likely to decrease during production planning, it sells futures first in the futures market and buys back futures during the peak production period to make a profit in the spot market. losses can be compensated. In addition, if there is a risk that the price of electricity will rise when a sales contract is concluded, a broker can compensate for a loss in the spot market by first buying futures in the futures market and liquidating futures when the sales contract is fulfilled.
