The horticultural seed industry has made great progress in the last fifty years of its history after the independence of this country. The industry has accomplished self-sufficiency in major vegetable seeds and has even gained international competitive edge in certain crop seeds, particularly in hybrid cultivar development. However, the industry is facing a crisis at present coming from excessive competition among the domestic seed companies as well as the foreign currency crisis of the country. Several major seed companies have already been acquired by multinational corporations. Many people in the country as well as agriculturists are concerned about this situation. Although it is true that the industry is undergoing hard times, this crisis can be turned into a chance for making new progress depending on the joint efforts of the groups responsible, i.e., private companies, public institutions, and policy makers. Therefore, we have to turn this crisis into an opportunity for self-reform and progress. We should not be discouraged or give up. We Propose some ideas for the Progress of the seed industry. Public institutions and policy makers should do such things in cooperation as 1) training human resources for future breeders, 2) securing a wide range of genetic resources and improvement of the management system, 3) basic science research including biotechnology, 4) releasing breeding stocks from germplasm enhancement through use of exotic accessions, 5) support for breeding region- or use-specific cultivars, and 6) collection of foreign agricultural information for breeding cultivars for overseas markets. Eventually the responsible group for the final development of commercial cultivars, production, sales and management is private companies. Therefore, private companies also should have to do their best to develop competitive cultivars with a missionary spirit and endeavor for both domestic and overseas markets in cooperation with public institutions. Management based on competition, professionalism and rationalism is also urged. We are going to conclude with optimism that we can make a new vault of progress once the private and public sectors closely cooperate for the development of Korean horticultural seed industry by overcoming this crisis.

Purpose - This article analyzes the impact of macroeconomic variables of the United States, China, and Korea on KOSPI and VKOSPI, in that United States and China have a great influence on Korea, having an export-driven economy. Design/methodology/approach - The influence of US, China, and Korea interest rates, industrial production index, consumer price index, US employment index, Chinese real estate index, and Korea's foreign exchange reserves on KOSPI and VKOSPI is analyzed on monthly basis from Jan 2012 to Aug 2023, using multifactor model. Findings - The KOSPI showed a positive relationship with the U.S. industrial production index and Korea's foreign exchange reserves, and a negative relationship with the U.S. employment index and Chinese real estate index. The VKOSPI showed a positive relationship with the Chinese consumer price index, and a negative relationship with the U.S. interest rates, and Korean foreign exchange reserves. Next, dividing the analysis into two periods with the Covid crisis and the analysis by country, the impact of US macroeconomic variables on KOSPI was greater than Chinese ones and the impact of Chinese macroeconomic variables on VKOSPI was greater than US ones. The result of the forward predictive failure test confirmed that it was appropriate to divide the period into two periods with economic event, the Covid Crisis. After the Covid crisis, the impact of macroeconomic variables on KOSPI and VKOSPI increased. This reflects the financial market co-movements due to governments' policy coordination and central bank liquidity supply to overcome the crisis in the pandemic situation. Research implications or Originality - This study is meaningful in that it analyzed the effects of macroeconomic variables on KOSPI and VKOSPI simultaneously. In addition, the leverage effect can also be confirmed through the relationship between macroeconomic variables and KOSPI and VKOSPI. This article examined the fundamental changes in the Korean and global financial markets following the shock of Corona by applying this research model before and after Covid crisis.

2008년 9월 미국의 서브프라임 모기지 부실에 의한 리먼브러더스 사태로 시작된 글로벌 금융위기가 세계 건화물해운시장에도 영향을 끼쳐 건화물 물동량 감소와 선박의 공급과잉으로 세계 건화물해운산업과 조선산업에 심각한 불황을 유발하였다. 이러한 상황에서, 국제경제의 동향에 민감한 한국경제의 구조 여건상 한국의 건화물선해운기업(또는 건화물선사)도 2008년 이후 현재까지 어렵게 경영을 헤쳐가고 있다. 이와 같은 심각한 불황과 그 여파로 건화물선사의 수익이 급감 할 수밖에 없게 되었으며 열악한 재무구조로 인해 경영이 부실해지고 급기야 도산과 파산하는 해운기업이 속출하게 되었다. 이러한 점을 고려하여 동 연구는 2008년 글로벌 금융위기를 기점으로 2005년부터 2007년까지와 그 후 2010년부터 2012년까지로 기간을 선정한 다음 한국의 외항 건화물 해운기업을 건전기업과 부실기업으로 구분하여 두 기업집단 간의 주요 재무비율에 어떠한 변화와 차이가 있었는지 t 검정을 통해 분석하였다. 실증분석에서 두 집단 간에 차이를 보인 주요 재무비율로는 수익성비율과 성장성비율이다. 본 연구의 의의는 첫째, 해운기업 경영에도 역시 재무건전성에 대한 체계적인 관리가 중요하며 이를 위해 수익성이 높은 화물을 계약하는 영업전략이 중요하다. 둘째, 선박의 효율적인 운항 및 관리로 성장성이 지속되는 기업으로 경영해야 한다는 것이다.

A growing number of studies have examined the relevance and impact of social media in building organizational resilience, which the ability to recover from a crisis, in the field of emergency management. However, few studies have assessed how these emergency response organizations perceive their own use of social media in crisis situations. In attempting to fill this gap, this study conducted a structured survey with emergency-response organization representatives in Seoul, South Korea, to examine how such organizations evaluate their utilization of social media in an urban emergency situation and how their social media uses are related to promoting organizational resilience during adverse events such as a flood. Overall, the findings imply that organizations are not yet taking full advantage of social media. Respondent evaluations of their own social media use in all three assessment areas-information provision, information dissemination, and emotional messages-were not satisfactory. However, their perceptions of how well they utilize social media were positively related to how they view their organizational resilience. Therefore, it may be that these organizations realize the powerful role of social media in building organizational resilience but lack the knowledge and experience to make the best use of social media services.

This paper describes a novel disaster evacuation system using embedded systems such as smart devices for crisis and emergency management. In indoor environments deployed with the Bluetooth Low Energy(BLE) beacons, smart devices detect their indoor positions from beacon messages and interact with Map Server(MS) and Route Server(RS) in the Internet over the LTE and/or Wi-Fi functions. The MS and RS generate an optimal path to the nearest emergency exit based on a novel graph generation method for less route computation, called the Disaster Evacuation Graph(DEG), for each smart device. The DEG also enables efficient processing of some constraints in the computation of route, such as load balancing in situation of different capacities of paths or exits. All data interfaces among three system components, the MS, RS, smart devices, have been defined for modular implementation of our disaster evacuation system. Our experimental system has been deployed and tested in our building thoroughly and gives a good evidence that the modular design of the system and a novel approach to compute emergency route based on the DEG is competitive and viable.

Ukraine has a significant in quantity and unique in quality parameters, in particular, the level of education, a resource - the labor force, which, along with natural resources, can serve as the basis for economic growth and the achievement of sustainable development goals. The study is aimed at a thorough identification of the main factors influencing the formation and use of the labor force in Ukraine, including by comparing with the indicators of the EU countries, before the start of the active phase of military aggression by the Russian Federation. It was found that until February 24, 2022, there were negative trends in the change in the quantitative and qualitative indicators of the labor force due to the demographic crisis, the transformation of the national economy and shortcomings in state regulation of labor market development processes. The military actions not only exacerbated pre-existing problems, but also led to the emergence of new ones. A significant number of refugees and internally displaced persons, with the termination of the activities of half of the economic entities, provoked a sharp increase in real unemployment and a decrease in wages. The specific problem of the labor market of Ukraine - the "labor crisis", which has and will have a significant impact on the labor force, is carefully considered.

Coronavirus disease 2019 (COVID-19) has had a significant impact on our society as a whole. The COVID-19 pandemic is not only a health crisis, it is also an economic, social and humanitarian crisis. Considering the dramatic global economic and social impact that the crisis has engendered, the aviation system is standing on the doorstep of rapid transformation. In particular, the impact on the aviation and travel industries is enormous. Air travel to most countries has been suspended and blocked. Looking at Korea's current situation, COVID-19 has wholly changed the aviation industry. As COVID-19 spreads around the world, countries have come up with aviation safety measures. Infectious disease safety measures were established to protect passengers and crew members, and countries with collapsed medical systems extended the validity period for aviation medical examinations. In Korea, on August 11, the Ministry of Land, Infrastructure and Transport provided guidance on medical measures related to COVID-19 through an official letter of "Notification of cautions for pilots and air traffic control officers (ATCO) when COVID-19 is confirmed". Overseas countries such as the United States and the United Kingdom have announced regulations for aviation medical examination regulations in relation to COVID-19, and have set standards for returning to aviation after COVID-19 is confirmed. In this paper, we would like to investigate the regulations for aviation medical examination related to COVID-19.
