자금조달력이 부족한 건설기업은 수립된 건설정책에 적응하는데 상대적으로 많은 시간이 소요된다. 하지만, 금융기관이 담보력과 신용도가 낮은 건설기업에 금융상품을 제공하는 비율은 낮으며, 특히 중소건설기업이 금융상품을 제공받는 비율은 크게 낮다. 이 연구에서는 건설기업이 수립된 정부의 정책에 적응하는데 필요한 금융상품을 조사하고, 전문가 자문과 설문조사를 통해서 그 금융상품들에 대한 건설산업의 수요를 분석하였다. 또한, 조사된 금융상품들을 건설산업에 도입하기 위해서 개정이 필요한 법·제도를 조사하였다. 분석된 수요도와 개정이 필요한 법·제도 수를 기반으로, 건설산업에 금융상품을 도입할 경우의 우선순위를 분석하였으며, '회계사, 세무사, 변호사 등 전문가 컨설팅'의 우선순위가 가장 높은 것으로 나타났다. 향후 연구에서는 우선순위가 높은 금융상품을 건설산업에 도입하기 위한 금융상품의 개발기준과 개발방법에 대한 연구를 수행하고자 한다.

This paper analyzes factors affecting enterprise's financial risk listed on the Vietnam stock market. The panel data of research sample includes 524 non-financial listed enterprises on the Vietnam stock market for a period of eleven years, from 2009 to 2019. The Generalized Least Square (GLS) is employed to address econometric issues and to improve the accuracy of the regression coefficients. In this research, financial risk is measured by the Alexander Bathory model. Debt structure, Solvency, Profitability, Operational ability, Capital structure are independent variables in the study. Firm Size, firm age, growth rate are control variables. The model results show that in order to prevent and limit financial risk for enterprises listed on the Vietnam Stock Market, attention should be paid to variables reflecting Liability structure ratio, Quick Ratio, Return on Assets, Total asset turnover, Accounts receivable turnover, Net assets ratio and Fixed assets ratio. The empirical results show that there are differences in the impact of these factors on the financial risk in state-owned enterprises and non-state enterprises listed on the Vietnam stock market. The findings of this article are useful for business administrators, helping business managers make the right financial decisions to improve the efficiency of financial risk management in enterprises.

최근 지속가능경영에 대한 관심이 증대되면서, 환경규제의 중요성이 부각되고 있다. 이러한 중요성에도 불구하고 기업경영과 환경규제의 연관성에 대한 연구가 부족한 상태이다. 이에 본 연구는 환경규제 준수능력과 기업경영의 관계를 기술적, 재무적, 구조적 측면에서 실증분석 하였다. 분석은 2003년부터 2007년까지의 국내상장기업과 외감법 기업의 경영성과를 분석대상으로 로짓분석을 실시하였다. 그 결과 첫째, R&D투자비중이 높을수록 환경규제준수능력이 있는 것으로 확인되었는데, 이는 R&D투자 확대를 통한 기술력의 향상이 환경규제준수능력을 증대 시킨 것으로 판단된다. 둘째, 기업의 재무적 측면인 유동비율, 부채비율, 현금흐름, 영업이익률은 환경규제준수능력과 유의한 관련성이 없었다. 이는 재무성과가 더 좋은 기업일지라도 반드시 환경에 투자를 하는 것이 아니라는 것을 시사하고 있다. 셋째, 구조적 측면인 자본집약도와 종업원비중, 기업규모(size), 수출비중이 환경규제 위반과 준수능력에 영향을 미치는지 검증하였다. 유형자산이 많은 자본집약적 기업일수록 환경규제를 위반한다는 것을 알 수 있었다. 반면에 기업규모가 클수록, 종업원비중이 높을수록 환경규제준수능력이 있는 것으로 나타났다. 기업규모가 크면 PR, IR등 대외관계가 중요하기 때문에 환경규제를 준수하고자 노력할 것으로 여겨진다. 반면에, 수출비중과의 관계에서는 유의한 결과를 얻지 못하였다. 마지막으로, 지배주주지분율이 높을수록 환경규제위반에 영향을 줄 것이라는 가설은 신뢰할 수 있는 결과를 얻지 못하고 기각되었다.

Purpose: This research is to answer the following research questions because of the importance of learning how retired businesspeople increase their financial security and quality of life. (1) how does an entrepreneur contribute to economic development? (2) what types of investments are performed by businesspeople after retirement? (3) how entrepreneurial financial attainment capacity and anticipated net income after retirement are related? Research design, data and methodology: This research has conducted the qualitative analysis (QCA) using the current literature review. In the traditional positivist research paradigm, the quality of research is evaluated based on issues of validity, reliability, and objectivity. Contrary to the positivist approach, QCA focuses on the underlying meaning of the data. Results: This research found that finance management is increasingly challenging for businesspeople. The solutions based on the literature investigation suggest four categories. (1) Planned spending and revenue allocation, (2) Investing in the stock market, (3) Create a culture of saving, (4) Get Informed. Conclusions: This research puts forth a model to describe the connection between an investor's financial achievement potential and their desired net profits in retirement. The results of this study support the idea that the ability to achieve financial success as an entrepreneur has a salutary effect on the amount of money saved for retirement.

MIFARE Classic is the most popular contactless smart card, which is primarily used in the management of access control and public transport payment systems. It has several security features such as the proprietary stream cipher Crypto 1, a challenge-response mutual authentication protocol, and a random number generator. Unfortunately, multiple studies have reported structural flaws in its security features. Furthermore, various attack methods that target genuine MIFARE Classic cards or readers have been proposed to crack the card. From a practical perspective, these attacks can be partitioned according to the attacker's ability. However, this measure is insufficient to determine the optimal attack flow due to the refined random number generator. Most card-only attack methods assume a predicted or fixed random number, whereas several commercial cards use unpredictable and unfixable random numbers. In this paper, we propose optimal MIFARE Classic attack procedures with regards to the type of random number generator, as well as an adversary's ability. In addition, we show actual attack results from our portable experimental setup, which is comprised of a commercially developed attack device, a smartphone, and our own application retrieving secret data and sector key.

In this study, an empirical analysis of 55 ship finance cases executed by a specific ship finance bank from 2009 to 2016 during the recession period was conducted. The purpose of this study was to find the factors affecting changes in the debt performance of Korean shipping companies. The main factors were the loan nature (investment purpose, loan-to-value (LTV), syndicated loans, loan terms, put-option, balloon, and spread), financial nature (total assets turnover, net profit-to-sales ratio, debt ratio, quick ratio, total borrowing, bonds payable to total assets, interest expenses-to-sales ratio, debt service coverage ratio (DSCR), and total assets), and the company nature (company age, chief executive officer's (CEO's) shares, and listing status). In this study, the factors affecting the debt repayment capability of domestic shipping companies (loan nature, financial nature, and company nature) were verified. The credit rating was used to measure the dependent variable, debt repayment ability. The variables of investment purpose, put-option, balloon, and spread in the loan nature, debt ratio in the financial nature, and the CEO's shares and company age in the company nature were found to be significant.

In the early industrial age which with high intensity of machine and labor, using financial measurement index was good enough to tie in company's mechanization and philosophy of management and been in efficiency. But being comply with "New Economic age," a new economic environment is full of knowledge and information, the enterprise competition had changed from tangible assets, plants to intangible innovation ability of knowledge. As recognizing the new tendency by enterprise, they value gradually the growth and influence from learning. Practice of organization learning not only needs firm structure and be in coordination with both hardware and software, but also needs an affect measurement model to offer enterprise to estimate learning performance. It's a good instrument of financial performance measure mold in the past years, But it's for measuring the past, couldn't formulate enterprise trend to future, hard to estimate investment for future, such as development of products, organization learning, knowledge management etc, as which intangible assets and knowledge ability just the key factors of being win around competition environment in the future. In 1992, Kaplan and Norton brought up Balance Scorecard (BSC) on Harvard Business Review, as an instrument helping enterprise to measure performance, which is being considered to be a most influence management instrument. It added non-financial index such as customer, internal process and learning growth besides traditional financial index, as offering enterprise an index to measure and manage intangible assets and intellectual property. As being aware of organization learning is hard to be ignored in the new economic age, this research is based on learning and growth of BSC, and citing one national material company try to let the most difficult measurement performance of organization learning, to be estimate through BSC, analyze of factor and individual case, to discuss the company how to make the related strategy and vision of organization learning to develop learning and growth of the structure of BSC, subject the matter of out put factors to be discussed, and measure the outcomes as a result of research. The research affect offers (1) the base implement procedure of carrying out BSC; (2) the reference of formulating measurement index while enterprise using BSC to estimate performance of organization learning; (3) the possibility bottleneck maybe forcing while carrying out BSC, to be an improvement or preventive for enterprise.

Construction contactors must continuously seek to improve their cash flows, which reside at the heart of their financial success. They require careful planning, analysis, and optimization to avoid the risk of bankruptcy, remain profitable, and secure long-term growth. Sources of cash include bank loans and retained earnings, which are conceptually similar in that they both incur a cost of capital. Financial management therefore requires accurate yet customizable modeling capabilities that can quantify all expenses, including said cost of capital. However, currently existing cash flow models in construction engineering and management have strongly simplified the manner in which interest is assessed, which may even lead to overstating it at a disadvantage to contractors. The variable nature of cash balances, especially in the early phases of construction projects, contribute to this challenging issue. This research therefore extends a new cash flow model with an accurate interest calculation. It utilizes singularity functions, so called because of their ability to flexibly model changes across any number of different ranges. The interest function is continuous for activity costs of any duration and allows the realistic case that activities may begin between integer time periods, which are often calendar months. Such fractional interest calculation has hitherto been lacking from the literature. It also provides insights into the self-referential behavior of compound interest for variable cash balances. The contribution of this study is twofold; augmenting the corpus of financial analysis theory with a new interest formula, whose strengths include its generic nature and that it can be evaluated at any fractional value of time, and providing construction managers with a tool to help improve and fine-tune the financial performance of their projects.
