  • This paper studies implications of financial conglomeration for both financial risk of individual conglomerates and systemic risk potential in post-crisis Korea. Our analyses suggest that we cannot conclude that financial conglomerates are taking on higher risks relative to non-conglomerate independent institutions. We also find that larger financial institutions show a significantly higher profitability and lower variability in profitability operating on a superior efficient frontier. However, it turns out that the consolidation has raised systemic risk potential as direct and indirect interdependencies among large banking institutions have substantially increased. Furthermore, financial conglomerates have become more vulnerable to contagion risks from non-bank sectors and capital markets. In the face of the shifting risk structure, financial supervisory and regulatory systems must be upgraded toward a more risk-based, consolidated supervision. Prompt corrective action provision for financial conglomerates must be based upon fully consolidated group risks, and effective supervisory devices need to be introduced to avoid inadvertent extension of public safety net to cross-sectoral activities of financial conglomerates. It is also critical to strengthen internal control and risk management capacities at financial conglomerates, and to establish strong market discipline by improving information transparency and monitoring incentives in the financial market.

  • Academia and research institutes mainly use qualitative methods that rely on expert judgments to understand and predict research trends and science and technology trends. Since such a technique has the disadvantage of requiring much time and money, in this study, science and technology trends were predicted using keyword network analysis. To that end, 13,618 AI (Artificial Intelligence) patent abstracts were analyzed using keyword network analysis in three separate lots based on the period of the submission of each abstract: analysis period 1 (January 1, 2002 - December 31, 2006), analysis period 2 (January 1, 2007 - December 31, 2011), and analysis period 3 (January 1, 2012 - December 31, 2016). According to the results of frequency analyses, keywords related to methods in the field of AI application appeared more frequently as time passed from analysis period 1 to analysis period 3. In keyword network analyses, the connectivity between keywords related to methods in the field of AI application and other keywords increased over time. In addition, when the connected keywords that showed increasing or decreasing trends during the entire analysis period were analyzed, it could be seen that the connectivity to methods and management in the field of AI application was strengthened while the connectivity to the field of basic science and technology was weakened. According to analysis of keyword connection centrality, the centrality value of the field of AI application increased over time. According to analysis of keyword mediation centrality during analysis period 3, keywords related to methodologies in the field of AI application showed the highest mediation value. Therefore, it is expected that methods in the field of AI application will play the role of powerful intermediaries in AI hereafter. The technique presented in this paper can be employed in the excavation of tasks related to regional innovation or in fields such as social issue visualization.

  • This study estimated the long-run and the short-run price and income elasticity of crude oil demand by using the ARDL model in Korea. First, the long-run cointegration relationship existed between crude oil demand and price or income in the ARDL-bounds tests. Second, the long-run own price, the cross price elasticity and the income elasticity were both statistically significant elastic and sensitive in the ARDL. Third, there was autocorrelation of the residuals, but no misspecification errors and heteroscedasticity, and then the residuals showed a normal distribution. And the CUSUM & CUSUMSQ tests showed that the coefficients were stable. Fourth, the short-run own price, the cross price elasticity and the income elasticity were both statistically significant elastic and sensitive in the ARDL-RECM. The ECM with the short-run dynamics showed rapid adjustments in the long-run equilibrium of oil demand after the economic crisis. In the short-run, the sensitivity of crude oil demand to price and income changes has moved in the same direction as the long-run case. Korea, depending too much on foreign crude oil, is vulnerable to the shocks of oil prices, so rising oil prices can certainly have a negative impact on Korea's trade balance. And the elasticity of long-run oil prices may help to control and manage Korea's oil demand. The government needs to strengthen monitoring of the country's policies and market trends related to crude oil, establish strategies to customize national policies and market conditions, and strengthen active market dominance efforts through pioneering new market and diversification.

  • Smart work is deeply embedded in our contemporary lives. This is called Smart Life. The expansion of communication, caused by smart life is utilized for the political purposes of politicians, political candidates, and political policies. Chiefly, smart life includes improvement in awareness, personal relations, and policy advocacy. Socially, smart life leads the proliferation of issues and civil movement. In particular, smart life has a significant effect on culture. In the case of K-POP, it is disseminated going beyond space time. It enhances economic value added by joining and sharing at the same time. Smart life has numerous advantages such as improving the quality of life, but it might cause inconvenience depending on users because there are differences in acceptance according to generations. Due to the heavy weight on the device, there are some side-effects such as lacking in human thinking, disclosure in private life, lacking in basic securities, increase in information addicts who are anxious when they do not get on the Internet or SNS, and interference with work. However, this inconvenience can change into convenience when users are accustomed to it. Like this, smart life influences politics, economy, society, and culture a lot. Working environment of smart life is a new paradigm, which can generate high performance through working in an exciting and bright atmosphere with easy economy and putting value on results.

  • The purposes of this study were to find smart-phone addiction how to mediate between worker's stress, anxiety and work commitment. The subject of survey was 329 workers in a public cooperation, and the data were analyzed by AMOS 18.0. The major findings were as follows; First, the higher the stress and anxiety, the more the direct effect on smartphone addiction. Second, smartphone addiction showed a significant negative relationship with work commitment. Third, smartphone addiction played a mediating role in the relationship between stress, anxiety, and work commitment. Workers with high levels of stress and anxiety were over-dependent on smartphones, which resulted in a decrease in work commitment. In order to prevent the problem of smartphone addiction of workers, it is necessary to prepare guidelines for correct use of smartphone in the workplace and service support should be provided according to the level of addiction. In addition, in order to improve work commitment, active support from the aspect of corporate welfare is needed to manage stress well. Finally, this study has a policy implication in that it reveals the route leading to smartphone addiction.

  • 리더십에 관한 연구는 리더십 특성요인연구, 리더십 contingency 연구, 특성이론적 접근, 행동적 접근, 상황이론적 접근 등이 있으나, 이러한 접근방법이 언제나 긍정적인 리더십을 유발하는 것은 아닌 것으로 나타나고 있다. 따라서, 긍정적이고 일관된 리더십을 만들어 내기 위해서는 리더십에 대한 새로운 접근이 요청된다. 리더십에 대한 연구는 매우 다양하게 나타나고 있으나, 문헌연구에서 볼 때 리더십은 파워라는 공통 요소를 가지고 있다. 파워는 사람으로 하여금 목적지향적인 행동을 유발하는 능력이며, 문헌에 나타난 리더십의 개념은 조직구성원으로 하여금 목적지향적인 행동을 하게하는 능력이다. 따라서, 리더십은 권력의 한 유형으로 볼 수 있다. 그러므로, 본 연구에서는 리더십을 power process에 기초한 권력순환적 관점에서 연구하고자 한다. Power process는 권력요소, 가치, 욕구, 환경, 관계의 다섯 가지 권력결정요소들의 상호작용 과정이다. 이러한 상호작용을 통해서 power process는 권력의 원천을 창출하는데 이 원천에 의한 권력행사는 긍정적인 결과를 유발한다(이경환, 2001). 앞에서 지적한 바와 같이 리더십은 권력의 한 유형이므로, power process에 의한 리더십 행사를 실증연구를 함으로서 지식경영시스템 구축을 위한 요인을 제시하고자 한다. 본 실증적 연구에서 리더는 자신의 권력요소(타고난 능력, 소질, 경험 등=경영자특성)와 욕구, 가치(경영철학) 관계성 및 환경과 같은 파워결정요소(리더십 결정요소)의 상호작용을 통해 자신의 리더십 원천을 창출할 때 즉, power process를 통해 리더십을 행사할 때 이러한 리더십은 경영성과에 긍정적인 결과를 유발하는 것으로 나타났다. 그러므로, 리더십 성과 향상을 위한 지식경영정보시스템은 파워결정요소적 측면에서 고려되어야 할 것이다. 모델과 독립성 모델에서는 시스템 등급에 영향을 준다. 향후에는 더욱 더 다양한 상호의존 모델들이 정량화될 필요성이 있다고 본다. 진행하였다. 줄여서 보다 더 정확하고, 지능적인 규칙구성요소 추출 방법론을 제시하고 구현하여 지식관리자의 규칙습득에 대한 부담을 줄여 주고자 한다. 도움을 받을 수 있게 되었다.을 거치도록 되어있다. 교통주제도는 국가의 교통정책결정과 관련분야의 기초자료로서 다양하게 활용되고 있으며, 특히 ITS 노드/링크 기본지도로 활용되는 등 교통 분야의 중요한 지리정보로서 구축되고 있다..20{\pm}0.37L$, 72시간에 $1.33{\pm}0.33L$로 유의한 차이를 보였으므로(F=6.153, P=0.004), 술 후 폐환기능 회복에 효과가 있다. 4) 실험군과 대조군의 수술 후 노력성 폐활량은 수술 후 72시간에서 실험군이 $1.90{\pm}0.61L$, 대조군이 $1.51{\pm}0.38L$로 유의한 차이를 보였다(t=2.620, P=0.013). 5) 실험군과 대조군의 수술 후 일초 노력성 호기량은 수술 후 24시간에서 $1.33{\pm}0.56L,\;1.00{\ge}0.28L$로 유의한 차이를 보였고(t=2.530, P=0.017), 술 후 72시간에서 $1.72{\pm}0.65L,\;1.33{\pm}0.3L$로 유의한 차이를 보였다(t=2.540, P=0.016). 6) 대상자의 술 후 폐환기능에 영향을 미치는 요인은 성별로 나타났다. 이에 따른 폐환기능의 차이를 보면, 실험군의 술 후 노력성 폐활량이 48시간에 남자($1.78{\pm}0.61L$)가 여자($1.27{\pm}0.45L$)보다 더 높게 나타났으며 (t=2.170, P=0.042),

  • Throughout various data sources, it is widely observed that air quality in South Korea has become improved. Koreans, however, insist that their health status and economic burden due to worsened air quality get degenerated. This study aims to explain the mismatch between perception and measured data, air pollution-led medical expenses, and consumption behaviors in the economics perspectives. First, we demonstrated data-driven evidence of mismatch in the perceived severity of air pollution and its enhancement in measured data. Second, using the health demand model, we theoretically derived and empirically showed a co-rising relation between air pollution severity and medical expenses. Last, we analyzed that the perception led to increased defensive expenditures in consumption. This result implies the possibility of overestimation in air pollution impacts on socioeconomic losses and its possible reverse interpretation from increased social benefit after improved air quality. Our results recommend policy consideration to strengthen air quality standards, to support socially vulnerable groups regarding defensive expenditures, and to improve the accessibility and credibility of air pollution information.

  • This paper is to reclassify systematically the functions of urban river: that is, water supply, land management, transportation and energy source as social and economic function; formation of geomorphic surface, water-side landscape, community constitution and boundary and separation between regions as spatial function; and drainage of waste water, purification, habitation, and weather regulation as ecological function. On the basis of this reclassification, it can be argued that the socio-economic functions (eg. water supply) of the river among the functions of the river have been strongly mobilized in the process of modernization, while the spatial function and ecological function of urban river have been ignored. The Kumho river which flows through Daegu and the adjacent area has made a great contribution to the modem development process of the river basin area, but as a result of a selective development of a specific function of the river, that is the social and economic function, it now suffers from the lack of instream flow and is deprived of its original functions with the water pollution and degradation. Moreover the Daegu region seems no longer possible to develop on the dependence of the river. In order to overcome this kind of social and environmental crisis, this paper is to suggest both some principles and main evaluating indicators to restore the original and comprehensive functions of the river, and important measures to make the co-evolution of the city and the river possible.

  • A number of existing cadastral control stations have been destroyed and shifted by a long lapse of time and careless management. Also, results of them are partly poor owing to dependence on conventional survey method. Because of these, it is very difficult in use of results. Hereupon, correction of cadastral results is necessary in level of government. But it is very consumable to check and adjust results with existing equipments and related techniques only. It is required that this problem can be resolved efficiently. This study analyzed the conformability for cadastral control network to GPS, GPS, which determine precise 3-D coordinates on a short time, to positioning of cadastral stations. We chose DaeJon city for the test area of this study and analyzed the precision of network composed of sixteen cadastral control stations. We made comparision the old result and the new outcome which obtained from coordinate transformation method and horizontal network adjustment method. As a result of this, we detected the blunder of cadastral stations. Furthermore, we suggested effective network type according to precision analysis of GPS observation network. Therefore, there is no doubt that GPS surveying can be applied to checking and adjustment of cadastral control network. Hereafter, it is expected that the practical use of GPS is advanced in a field of cadastration.

  • For nursing as a science to establish a unique system of knowledge, nursing researchers should include the philosophical activities such as establish of nursing philosophy. For establish of philosophy nursing, the nature and realms and essential characteristics of nursing science should be made clear at first. The purpose of this study identify alienation and the situation of happen to alienation and Martin Buber Philosophy(I and Thou). Understanding of this concept should enlighten nurses to interaction and relationship problems between patients and nurse and thus lead to further toward enhancing these interaction and relationship. The alienation was serious problem in present society which was cultural, political, economical, mechanical, religious classified. The overcome of alienation in nursing situation was caring and interpersonal relationship based on Martin Buber philosophy. The essential philosophy of Martin Buber was "I and Thou" relationship. I and Thou relationship are consist of five characteristics ; 1)mutuality 2)directness 3)presentness 4)intensity 5)ineffability As health care technology becomes more sophisticated, there is a tendency to rely on monitors and machines to assess the patient's status. Therefore focus on the functioning and care of machine can result in less meaningful communication with patients. This study points to the need for health professional and patient relationship based on Martin Buber philosophy(I and Thou). This relationship may suggest that professional shoud have sincerity, concerning, respect and warm emotional toward their patients. Ultimately this study provide the basic information to contribute understanding of "I and Thou" relationship and nursing philosophy development in nursing education.
