Corona-virus(COVID-19), which has affected the world economy and Korea economy widely since 2020 could have an effect on management future perspectives. Thus this paper investigate whether the effect of COVID-19 pandemic on cost stickiness is contingent on operating uncertainty. By using the sample listed in KOSPI and KOSDAQ from 2018 to 2020. I find that COVID-19 increase cost stickiness when sales growth volatility is low. This paper contribute to the literature by providing the empirical evidence which contains that the effect of COVID-19 on cost stickiness varies with operating uncertainty.

저조한 해운시황과 고유가가 지속되고 이들 변수의 변동성이 커지면서 두 변수가 해운업체의 영업수익성에 미치는 영향도 커지고 있다. 금융위기 이후 급감한 해운 수요는 유럽 재정위기가 겹치며 쉽사리 증가하지 못하고 있는 반면, 호황기에 발주된 선박들이 대거 인도되어 선복량 공급은 꾸준히 증가하면서 선복량 수급 불균형이 시황 회복의 발목을 잡고 있다. 또한, 해운 운임과 유가의 변동성 확대는 해운시황 침체와 함께 불확실성을 증대시켰고, 그에 따라 해운업체 영업실적의 불확실성도 확대되었다. 뿐만 아니라 이들 변수의 움직임에 의해 영업수익성이 좌우되는 모습을 보이고 있다. 이에 해운 운임 및 연료유 가격과 해운업체 영업수익성의 상관관계를 분석적 관점에서 살며보고 이를 바탕으로 2013년 해운업체의 실적에 대해 전망해 보는 동시에 유동성 상황을 점검해 보았다. 다음은 한국기업평가에서 발표한 "해운업계 실적 전망과 유동성 점검"의 주요 내용을 요약 정리한 것이다.

This study examines what changes and impacts have brought to the corporate cash holding after the financial crisis. The main findings can be summarized by two parts. First, the recent high increase in cash holding is only found in few companies, meaning that the level of the overall ratio has not risen. Second, Korean companies tend to have a higher ratio of cash holding when they have more uncertainty about their business performances. The higher the uncertainty in overall business performances also has some effects on the cash holding patterns of the Korean companies.

This study, targeting KOSDAQ-listed companies, examined the relationship between variability of accruals and corporate characteristics. First, the analysis results show that executives of companies with high debt ratios are more likely to violate debt contracts, so there is a strong temptation to use discretionary accrual items. Second, for companies with large volatility in operating cash flows, Executives of these companies are strongly inclined to utilize accruals for the purpose of abuse of discretion. Third, the larger the company, the more sensitive it is to political costs, so it is less tempted to use the accruals item than a smaller company. Fourth, the corporate age is thought to be the maturity of the company, Executives of such companies have little room to use accruals to abuse their discretion. Fifth, in the case of profit dummy variables, the companies reporting losses have more temporary accrual items than those reporting profits, so this increases the uncertainty in their accounting information than the latter. Sixth, for those companies that are indicated as inappropriate as a result of audit, the more likely their executives are to use the accrual items, and the lower the quality of their accounting profits is. Lastly, Companies audited by 4 Big domestic accounting firms have less discretionary accrual fluctuations than companies audited by non-big 4 accounting firms. Thus, it was found that the accrual amount allows the discretion of corporate executives differently according to the characteristics of the company.

경영환경 변화와 필요성에 대한 인식이 높아져 많은 기업들이 정보화 투자를 수행했지만 여전히 중소기업에게는 비용 부담, 투자성과의 불확실성 등으로 인해 미진한 면이 없지 않다. 본 연구에서는 중소기업에 대한 실태조사를 통해 BSC에 기반하여 정보화에 따른 성과를 측정하고, 정보화 투자 유형에 대해 분석하였다. 그 결과 현재 가장 많은 투자가 이루어진 영역은 회계, 마케팅, 영업 관련 분야 순이며, 투자규모로는 제품개발 부문에 가장 많은 투자비가 소요되고 있는 것으로 나타났다. 투자 유형을 보면 9개 분야에 걸쳐 모두 정보화 시스템을 운영중인 기업은 3%에 불과하고 6.92%는 정보화 시스템이 하나도 없는 것으로 조사되었다. 각 분야별 정보화 시스템 운영을 통해 모두 성과가 유의할만한 차이를 나타내었으나 마케팅/서비스 분야는 그렇지 않은 것으로 나타났다. 또한 현재 중소기업들이 가장 선호하는 정보화 시스템과 이들이 어떤 패턴으로 정보화에 대한 투자를 진행해왔는지를 살펴볼 수 있었다. 이러한 시사점을 통해 향후 중소기업 정보화를 지원하는데 있어서 보다 더 효과적인 경로를 유추할 수 있고, 정책효과를 극대화하는데 일조할 수 있을 것이다.

As a result of this study only a few Korean firms have a certain management methods designed to predict the possibility of risk occurrence and establishment of systematic countermeasure. Besides, the Korean firms do not have enough data on the risk of Chinese Market. The risk management department inside the firm does not function efficiently, and when it comes to investigation of risk, it heavily depends on that of local branches. Accordingly, in order to accurately recognize and manage, the firms need to not only specialize risk management department but also outsource by using a consulting firm.

Today, the world has reached 'Industry 4.0'. Industry 4.0 has high uncertainty in various aspects because it is based on building a smart chain where the various elements that make up the industry can communicate with each other. Based on the above facts, based on the researches of the previous researchers, we have searched for the countermeasures of small and medium sized manufacturing companies in Korea in order to minimize the negative aspects of establishing the basic concepts and functioning of Industry 4.0. As a result, efforts to accurately identify and address the uncertainties of Industry 4.0 in a variety of ways will help to drive business growth and economic growth in the country through smart factories, which are at the heart of Industry 4.0.

Analysis about supply chain structure was achieved in product unit that is not 'business' dimension that is existent discussion target in surrounding and supply chain structure as that this study analyzes positively how supply chain structure according to business surroundings of product changes. This can do that analysis of product unit in synthetic supply chain management is essential when recognize the importance that supply chain management must consist by product special quality according to corporation's each product. Sort product environment and studied relation with supply chain structure to achieve study purpose hereupon. Structure variable of supply chain drew through existent literature study here. Executed question investigation for supply chain by product for study that is actual proof enemy, and figure method used analysis of variance (ANOVA) mainly. If summarize result of study, result that analyze relation between business environment of product and supply chain structure, according to business environment of product, showed that supply chain structure changes. Certified that relation of two group (environment group of uncertain product and environment group of stable product) of business environment of product and structure variable (that is number of participant of supply chain, lead time of supply chain, about administration's independence, response points of supply chain) of supply chain is significant relation all from all structure variables except number of participant of supply chain. Variable that express length of supply chain from structure Variable of supply chain is number of participant of supply chain and lead time of supply chain, and variable that display monitoring or trust aspect for supply chain is administration's independence degree and response points of supply chain. As analysis result, product that environment is uncertain is appearing more shortly than product that length of supply chain stabilizes, and also, monitoring or trust aspect for supply chain was proved that is consisting abuzzer than product that stabilize. Therefore, showed that put essential point in administration of 'hierarchy'putting first than 'market' when business environment designs supply chain structure in case of uncertain product, and proved that the other side business environment is focusing in administration way of 'market' putting first in case of stable product.

Abstract Infiltration of rainfall that may lead to reduce resistance force due to reduction of matric suction and to increase driving force due to increase of self weight makes the slope fail. There are many specifications to make slope stable based on factor of safety. Although result of slope stability analysis satisfy the specifications, slope failures triggered by rainfall are frequently occurred in reality because slope stability analysis cannot consider uncertainty of each soil properties. This is why conventional analysis has limitation and development of alternative method is needed. So it is suggested to adopt the reliability analysis rather than design based on factor of safety into designing safer structure. Through the evaluation of handicaps for the factor of safety based design, calculation of soil properties by site investigation, and reliability analysis considering distribution of each soil properties, distribution of failure probability in railway slope is obtained. Then, Risk assessment of slopes in Korean railway is executed from the results. Damage loss and incoming loss are considered as the loss. Using these results, it is possible to make proper countermeasure or efficient maintenance.
