  • Asset prices decline sharply and stock markets collapse when financial crisis happens. Recently we have encountered more frequent financial crises than ever. 1998 currency crisis and 2008 global financial crisis triggered academic researches on early warning systems that aim to detect the symptom of financial crisis in advance. This study proposes a risk recovery index for detection of good opportunities from financial market instability. We use SVM classifier algorithms to separate recovery period from unstable financial market data. Input variables are KOSPI index and V-KOSPI200 index. Our SVM algorithms show highly accurate forecasting results on testing data as well as training data. Risk recovery index is derived from our SVM-trained outputs. We develop a trading system that utilizes the suggested risk recovery index. The trading result records very high profit, that is, its annual return runs to 121%.

  • This paper studies whether export diversification mitigated the negative effect of the global financial crisis on exports using the Korean case. Specifically, we use annual data on the exports of 24 Korean manufacturing industries from 2000 to 2016 and examine whether the negative effect of the crisis on exports was less prevalent in industries that were more diversified in terms of country and product. We also examine whether export competitiveness, as measured by the revealed comparative advantage index by industry, had a mitigating effect on trade during the crisis. In order to study these issues, we use panel regression with a fixed-effect model for 24 Korean manufacturing industries. From our empirical analysis, we find that country diversification weakened the negative impact of the global financial crisis on Korea's exports, whereas neither product diversification nor export competitiveness did so.

  • The current research attempts to measure the level of the acceptance of the Blackboard System (BBS) during the Corona crisis, and whether this is one of the reasons for the low use of the BBS at Al-Jouf University. To achieve this, the technology accepting model in the time of crisis (TAMTC) has been proposed to measure the degree of acceptance by students, which was then applied to a random sample of 339 of such. The results show a high level of student acceptance, despite their lower use of the system. The research also highlights the importance of upgrading e-courses and that the discontinuation of exam disqualification of students is secondary to their poor course attendance.

  • This study argues that scholars lack an adequate conceptualization of the strategic use of social media framing by Ministries of Foreign Affairs (MFAs) during crises. As a theoretical starting point, this article employs the concept of soft disempowerment to suggest that MFAs may use online framing to limit an adversary's range of possible actions during a crisis by depicting that adversary as violating norms and values deemed desirable by the international community. Next, the article introduces the concept of mutually assured delegitimization (MAD), which suggests that actors may call into question one another's adherence with certain norms and values during crises, which results in the mutual depletion of soft power resources. Importantly, this article proposes a novel, methodological approach for the analysis of individual tweets during crises. To illustrate its methodological and conceptual innovations, the study analyzes tweets published by the MFAs of the United States (US) and Russia during the Crimea crisis and demonstrates that both MFAs used Twitter to negatively frame each other by calling their morals into question, which resulted in MAD.

  • 사이버공간은 시공간을 초월하여 범세계적으로 상호 밀접한 관계를 맺고 있으며, 이미 우리 생활의 가장 중요한 영역 중 하나로 자리 잡았다. 그러나 과거 1.25 인터넷 대란과 같은 전국적 규모의 국가 주요 정보통신망 마비사태 등에서처럼 국내 또는 해외로부터의 조직적인 사이버테러가 발생한다면 국가기밀 및 첨단기술의 유출 등 우리 사회 전반에 중대한 해악을 미칠 수 있는 사이버위기의 발생 가능성이 날로 증대하고 있다. 그러나 우리는 아직까지 국가적 차원에서 사이버안전 관리 업무를 체계적으로 수행할 수 있는 법제도적인 절차가 정립되어 있지 않아, 사이버위기 발생 시에 국가적 또는 개인적 측면에 막대한 손해를 끼칠 가능성이 높다. 이에 이 연구에서는 우리의 사이버안전 관련 입법례를 살펴보고, 주요국의 관련 법제에 대한 비교법적 검토를 통해 우리의 사이버안전 관리 규정의 개정방향에 관한 시사점을 제시하고자 한다.

  • 본 논문은 "공공정보의 대중화를 통해 시민의 알 권리를 실현하고 사회 전반의 투명성과 책임성을 높여나가는 것을 목적"으로 설립된 시민사회 단체인 '투명사회를 위한 정보공개센터'에서 <1997 외환위기 아카이브>를 만든 과정을 소개한다. 소규모 시민사회 단체에서도 충분히 주제 아카이브를 만들 수 있다는 다소 낙관적인 판단에서 작업을 시작했으나, 부족한 자원과 역량으로 아카이브를 구축하면서 많은 좌충우돌과 좌절, 그에 따른 방향의 수정이 거듭되었다. 하지만 시민이 주도하는 아카이브 고유의 필요와 의미에 공감하는 많은 사람들의 기여를 통해 난관을 극복하고 아카이브를 구축할 수 있었다. 논문에서는 구축 과정에 대한 소개와 함께 구체적인 어려움과 필요했던 역량들이 무엇인지, 특히 기록관리 분야에서 어떤 지식과 도움이 필요했는지 정리하였다. 아직 이용자 수는 2천명 남짓이지만 <1997 외환위기 아카이브>가 우리 삶의 토대를 흔들었던 과거를 우리 스스로의 힘으로 기억하고 재구성하는 좋은 사례로서, 그리고 더 나은 결정들에 조금이나마 보탬이 되는 도구로서 오래 기능하기를 바란다.

  • 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.

  • 세계 자동차산업은 제품 결함, 비윤리적 기업경영과 같은 다양한 위기를 겪어왔다. 본 연구는 세계 시장에서 가장 큰 비중을 차지하는 중국 소비자를 대상으로 자동차기업의 위기 커뮤니케이션 전략의 효과성을 검증하기 위해 위기책임성, 위기유형과 위기커뮤니케이션 전략이 기업태도, 부정적 커뮤니케이션 의도, 불매운동 참여의도에 미치는 영향을 분석하였다. 서울에 거주하는 중국인 학생 1,600명을 대상으로 2(위기책임성: 고·저) × 2(위기유형: 기업 능력/사회적 책임감) × 2(위기커뮤니케이션 전략: 수용/방어) 설계 실험을 실시하였다. 높은 위기책임성과 사회적 책임감 위기유형은 비호의적 기업태도, 높은 부정적 커뮤니케이션 의도와 불매운동 참여의도로 연결되었다. 위기책임성과 위기커뮤니케이션 전략은 유의한 상호작용을 보였다. 위기책임성이 높을 경우에는 수용 전략이 방어 전략보다 더 효과적으로 나타났으나 위기책임성이 낮은 경우에는 전략 간의 차이가 나타나지 않았다. 기업의 사회적 책임감 위기 경우에는 위기책임성에 상관없이 전략간 차이가 나타나지 않았고, 기업 능력 위기경우에는 위기책임성이 높을 때 수용 전략의 효과가 효과적으로 나타났다.

  • The purpose of this study is to clarify the definition of middle age, to compare the different perspectives about mid-life crisis, and to identify the variables that cause the mid-life crisis of men and women.. For this purpose reviewing literatures and emprical research were conducted. For the emprical research, Mid-life Crisis Scale, Mid-life Indentity Scale, Family Relation Scale. Health Scale and Religious Scale were developed. The Sample was selected form the men and women living in Seoul, whose age is from 40 to 59 , and whose last child is older than 13 years of age. Among 820 respondents 218 men and 442 women were finally selected as datum sources. The data were analyzed by the statistical method such as the factor analysis frequency distribution, percentile, ANOVA, Pearson's correlation and regression analysis. The main results were as follows; 1) Men and women experience mid-life crisis some extent. The mid-life crisis score for men is 33.60 and 35.0 for women. This implies women reveal significantly higher crisis than men. As for women's mid-life crisis. self-awaring age, education, income, husband's occupation, employment status of wife and occupational status of wife have a significant influence Expecially employment status of wife seemed to interact with sex, husband's occupation and educational level of wife. however status of child, family pattern, son's existence are not as important an influence on mid-life crisis. 3) Among the psychological variables, work identity and physical identity have the strong influence on the mid-life crisis of men and women, It implies that mid-life crisis si lower when one has higher work identity and physical identity. 4) Mid -life crisis of men and women is influenced significantly according to family relation variables and health variables. It reveals that the better one's family relations and health sate, the lower one's mid-life crisis is. However menopause and the years after menopause do not influence on the mid-life crisis of women. 5) Mid-life crisis of women differs significantly according to the kind of religion and religious activity. That is mid-life crisis of women is lower when she believes in Protestantism and Catholicism and participate in more religious activity. Mid-life crisis of men is not significantly influenced by religious variables. After all among the five categories of variables that related to mid-life crisis, psychological variables-especially work identity and physical identity are observed to have the strongest degree of significance.

  • The purpose of this research is to understand the levels of crisis and quality of life and the relationship between them. Data was collected from questionnaires completed by 384 middle-aged women between 40 and 59 years old. The sense of crisis was measured by a scale which was developed by Kim(1988) and modified by Oh(1999). The quality of life was measured by the scale which was developed by Noh(1988). The data was analyzed using the SPSS (Statistical Package for the Social Sciences) program and included: descriptive statistics, Pearson correlation, and stepwise regression. The results of this study were as follows: 1) In the sense of crisis scale, 'experiencing emptiness and powerlessness through my friends is the highest item($3.56{\pm}1.06$). 'Meaninglessness in daily living' factor's score is $3.16{\pm}0.76$ and another factor, 'concept of my life thus far' score is $2.89{\pm}0.74$. Then the former is higher than the latter. 2) In the quality of life, 'eat well now' is the highest item($3.60{\pm}0.93$). 'self-esteem' is the highest factor($3.37{\pm}0.62$) and 'emotional state' is the lowest factor($2.89{\pm}0.31$). 3) According to the correlation between factors of crisis and quality of life, there was a significant negative correlation between two factors of crisis and five factors of quality of life except emotional state. 4) According to linear regression, two factors of the sense of crisis showed the explanatory power of the quality of life with 31.6%. On the basis of above findings, the following is suggested; Crisis is not precipitated by special events and new accidents, but the normal emotional change phenomena process in the human life cycle. As a result, we should develop the nursing programs and education programs about crisis intervention for middle-aged women's health.
