Purpose - This research empirically proves that global shipbuilding industry leadership has moved to China from Korea. Design/Methodology - Competitiveness is measured by AHP for the weights of comprehensive competitiveness, which is the output mixture of three attributive factors: shipbuilding technology, shipbuilding contract price, and export credit. Findings - China is far ahead of Korea for standard vessels such as bulkers and containerships with competitiveness weights of 0.762 and 0.612, respectively, against 0.238 and 0.388 of Korea. Korea is maintaining its competitiveness only in LNG carriers (174k CBM) with a competitiveness weight 0.621. China and Korea have similar competitiveness for chemical carriers, complex vessels with a small hull size. The sources of Chinese competitiveness are shipbuilding contract price and export credit. With the majority share of standard vessel types in the world fleet, China will hold a bigger market share than Korea in the global shipbuilding industry in the forthcoming years. Implications - The swing factors of market power are shipbuilding technology and contract price. If China fails to further develop shipbuilding technology for shipowners worried about the reliability of the Chinese-built vessels, shipowners may swing back to Korea. The rising Chinese labor cost will expedite this swing in the forthcoming competition. Originality/value - To the best of the author's knowledge, this is the first paper that quantitatively examines the competitiveness of shipbuilding between China and Korea by comparing attributive factors for competitiveness.

This paper presents a system called a Cash-flow based Construction Schedule Optimization system(CfSO). The existing CPM effectively handles schedule and cost management. However, funding strategy should be considered to obtain maximum profit and to progress a project favorably. One of measures is to coordinate the contract terms between owner and subcontractors (or suppliers). Contractor may decrease the interest cost attributed to project financing by adjusting the timing of cash-inflows and cash-outflows. It is an excellent method maximizing profits. This paper presents a method to estimate the amount of a cash-flow occurred periodically by integrating the terms of contract into scheduling. The proposed method is implemented as a system prototype in Microsoft Excel. This system provides a user an automated tool that identifies an optimal schedule that secures maximum profit by adjusting start and finish times of non-critical activities' free-floats without affecting on the project completion time. This system supports a project manager to establish an optimum project schedule and identifies profitable contractual conditions against to a construction owner.

본 연구는 CSR활동의 성과가 기업의 가치에 미치는 영향을 공급계약 공시라는 주요 이해관계자와의 사건을 통하여 실증적으로 연구 분석하였다. 경제정의실천연구소에서 제공하는 CSR성과지표인 KEJI Index와 한국거래소의 공급계약 공시를 이용한 연구결과, CSR의 성과가 높을수록 공급계약을 맺을 확률이 낮았으며 공시일의 누적비정상수익률도 낮았다. 동결과는 기업의 CSR활동이 주주의 부를 감소시킨다는 CSR에 대한 부정적인 견해를 지지한다. 그러나 이러한 CSR활동의 부정적인 영향은 CSR성과의 수준별로 차이가 있으며, 최상위의 성과를 낸 경우에는 이러한 부정적인 영향이 없고, 차상위의 성과를 낸 경우에 이러한 부정적인 영향의 대부분이 집중되어 있었다. 이는 최상위의 성과를 내는데 실패한 CSR활동은 기업 가치에 부정적인 영향을 줌을 암시한다.

Purpose - Although various studies have been conducted on the stress of service employees, there are still lack of studies regarding job stress and job satisfaction of call center workers. Especially there are quite few studies on the job stress according to employment type. This study focused on job stress and job satisfaction for call center employees and the correlation between the two factors and aimed to provide basic materials for seeking for the plans to reduce job stress and improve job satisfaction. Research design, data, and methodology - Frequency, percentage, and mean value were calculated through descriptive statistics in order to find out demographic characteristics, level of job stress, and job satisfaction. Differences in job stress according to employment type were calculated by using one-way ANOVA. Correlation between job stress and job satisfaction were identified through empirical analysis with Pearson's correlation coefficient. 150 materials were used for final analysis. The collected materials were analyzed to get statistics by using SPSS 20. Results - First, as for the job stress of call center workers, overall mean value was 2.54 in 4-point scales. Among the six sub-factors, job demands had the highest score, which was 2.67. Second, as for the job stress according to employment type, others showed higher score than mean value followed by contract job and full-time job in that order, in terms of job insecurity and organizational system. In terms of inappropriate remuneration, contract job showed higher score than mean value followed by others and full-time job. Third, as for the satisfaction with job, the mean value was 2.37 in 4-point scale and "very much satisfied" was only 3.3%. Lastly, in terms of job stress and job satisfaction, all sub-factors except for job demands showed significant correlation. The more job stress increased, the more job satisfaction decreased. Conclusions - First, as a result of analyzing job stress according to the employment type of call center workers, job stress increased more when the employment type was not full-time. Therefore, it was assumed that self-rescue efforts should be followed for effective employment management of call center business where contract employment takes most part as well as efforts to transfer them to full-time job. Second, decrease in job satisfaction of call center workers may affect the performance of an organization as well as service quality of the company providing the service. Therefore, various supports are required to decrease job stress and increase job satisfaction for call center workers through the expansion of rest area or break time. Third, I could recognize that there were lack of academic research on call center business in the whole service industry. Therefore, further research should be conducted more actively in the future. In particular, this study has special significance in the aspect that there were few studies on the job stress of call center workers according to employment type.

This paper, wireless internet such as Wi-Fi has a vulnerability to security. Blockchain also means a 'Ledger' in which transaction information that occurs on a public or private network is encrypted and shared among the network participants. Blockchain maintains information integrity by making it impossible for a particular node to tamper with information arbitrarily, a feature that would result in changes in the overall blockchain hash value if any one transaction information that constitutes a block was changed. The complete sharing of information through a peer-to-peer network will also cripple hacking attempts from outside, targeting specialized nodes, and prepare for the "single point of failure" risk of the entire system being shut down. Due to the value of these Blockchain, various types of Blockchain are emerging, and related technology development efforts are also actively underway. Various business models such as public block chains such as Bitcoin, as well as private block chains that allow only certain authorized nodes to participate, or consortium block chains operated by a select few licensed groups, are being utilized. In terms of technological evolution, Blockchain also shows the potential to grow beyond cryptocurrency into an online platform that allows all kinds of transactions with the advent of 'Smart Contract'. By using Blockchain technology, the company makes suggestions to overcome the vulnerability of wireless Internet.

Good faith is difficult to define due to the facts that there is not an objective and concrete concept of good faith, and good faith in contracts for the international sale of goods is a principle that parties to the contract must act with sincerity as members of a social community. The Korean Supreme Court shall pay attention to setting the applicable standards that can be universally applied to good faith based on the self-established criteria. Through such effort, it is possible not only to realize the value of concrete validity pursued by the general clause of good faith but also to realize the value of legal stability by assuring the predictability of results when applying good faith. In the modern sense, it can be said that the arbitrary application of general rules rather than the escape and general clauses is a problematic situation in the application of good faith, but this problem can be solved by setting a reasonable standard of good faith. This paper studies good faith in the view of Korean law, international laws, and related cases in contract law. The purpose of this paper is to find the problems and solutions of the practical application of good faith by analyzing the Korean case (2009Da86000), which undermined the legal stability of good faith in Korea.

Rapid spread of intermittent renewable energy has amplified the instability and uncertainty of power systems. The Korea Power Exchange (KPX) promoted efficient management by opening the power brokerage market in 2019. By combining small-scale intermittent renewable energy with a flexible facility through the power brokerage market, the KPX aims to develop a virtual power plant system that will allow the conversion of existing intermittent renewable energy into collective power plants. However, the participation rate of renewable power owners in the power brokerage market is relatively low because other markets such as the small solar power contract market or the Korea Electric Power Corporation power purchase agreement are more profitable. In this study, we used a choice experiment to determine the attributes affecting the participation rate in the power brokerage market for 113 renewable power owners and estimate the value of the power brokerage market. According to the estimation results, a low smart meter installation cost, low profit variations, long contract periods, and few clearances increased the probability of participation. Moreover, the average value of the power brokerage market was estimated to be 2.63 million KRW per power owner.

Commercial transactions, one of the pillars of the capitalist economy, are occurring countless times every day, especially small and medium-sized businesses. However, small and medium-sized enterprises are bound to be the legal underdogs in contracts for commercial transactions and do not receive legal support for contracts for fair and legitimate commercial transactions. When subcontracting contracts are concluded among small and medium-sized enterprises, 58.2% of them do not apply standard contracts and sign contracts that have not undergone legal review. In order to support small and medium-sized enterprises' fair and legitimate contracts, small and medium-sized enterprises can be protected from legal threats if they can reduce the risk of signing contracts by analyzing various risks in the contract and analyzing and informing them of toxic clauses and omitted contracts in advance. We propose a risk prediction model for the machine reading-based legal contract to minimize legal damage to small and medium-sized business owners in the legal blind spots. We have established our own set of legal questions and answers based on the legal data disclosed for the purpose of building a model specialized in legal contracts. Quantitative verification was carried out through indicators such as EM and F1 Score by applying pine tuning and hostile learning to pre-learned machine reading models. The highest F1 score was 87.93, with an EM value of 72.41.

Purpose - This study aims to identify the internal capabilities that export companies need to possess in order to utilize FTAs and to propose ways to expand their export performance through them. To achieve this goal, the study analyzed the internal factors that affect FTA utilization from a resource-based perspective, such as Origin Management Competency, Information Acquisition Competency, contract Management Competency, and Commitment to Export, based on prior research on corporate capabilities in the field of management and FTA-related research. The study ultimately aims to confirm whether a company's FTA utilization contributes to its export performance through the management and response to its internal factors for FTA utilization. Design/methodology - To achieve the research objective, this study conducted a literature review related to FTA utilization and identified the internal factors of companies that affect FTA by classifying them into Origin Management Competency, Information Acquisition Competency, contract Management Competency, and Commitment to Export Based on this, a final research model was developed, hypotheses were set through a preliminary study survey, and conclusions were drawn by analyzing the data of 312 companies. Findings - The empirical analysis results indicate that Origin Management Competency and Contract Management Competency have a positive impact on FTA utilization, while Information Acquisition Competency and Commitment to Export do not have a statistically significant impact on FTA utilization. Based on these findings, this study suggests measures for efficient FTA utilization for companies that want to utilize FTAs. Additionally, FTA utilization has a positive impact on export performance. In other words, the extent to which companies utilize the signed agreements has a positive impact on their performance. Based on these results, this study identifies the characteristics of companies that want to utilize FTAs and proposes measures for future efficient FTA utilization. Originality/value - This study has confirmed that in order for companies to utilize FTAs, they must meet the requirements of the FTA. To this end, the study has concluded that it is important to manage and address internal factors such as Origin Management Competency, Information Acquisition Competency, contract Management Competency, and Commitment to Export to increase FTA utilization. Based on these results, it can be confirmed that it is essential for companies to have an understanding and management of the internal factors that satisfy the requirements of the FTA in order to utilize the FTA.
