On the day of 24 February 2022, Ukraine was invaded by Russia which signed to ensure definitely the Ukraine's national sovereignty, territorial integrity and security under the UN General Assembly Security Council A/49/765, named as the Budapest Agreement. This invasion is the 2nd invasion succeeded in Crimean Peninsula invasion of March 2014 after the Ukraine's national independence in 1991 from the USSR. However this invasion has been continuing for much more than one year. Although Ukraine President appealed the 'peace' toward Russia and claimed also to justify the Budapest Agreement of 1994 toward U.S.A., even any justifications were not appealed. The critical moment of the national abolition could be escaped from the unified desperate spirit of all nations including the president, political-social leaders and military members. Such patriotic and self-help spirits in Ukraine resulted in the active supports from the U.S.A., western and eastern free democratic countries, NATO and EU, and even the neutral countries. Furthermore these supports are increasing much more day-after-day. The lessons which the Ukraine War offers to the Korean national security should be cored with the development of self-reliant national defense capabilities, self-strenuous efforts and unity strengthening of the Korean-U.S. Alliance with the deep confidence.

ESG management means to thoroughly consider the investor's perspective when evaluating corporate value, and environmental, social, and governance issues are continuous and strategic monitoring issues in identifying risk and opportunity factors related to corporate management activities. In other words, the perspective of value creation is reflected in business relationships. The fundamental purpose of ESG management is continuous business value creation and thorough management of investment risks and business transactions in contractual relationships. It is also a requirement of linked investors. The field that Korean companies are currently experiencing the most is the recognition that 'ESG information collection is necessary and maintenance must be prioritized' in investor IR and global sales and marketing departments, and the primary need for this is emerging. In addition, as the legal affairs office, environmental safety department, and human resources department, which conduct compliance management, carry out related tasks, clarity at the organizational level must precede in order to properly establish an information integration and management system. It covers the scope of securing new market opportunities such as management, disclosure and communication. Therefore, in regard to the newly emerging ESG management and response methods, it is necessary to review and implement it repeatedly so that sustainable exchange profits can be created by simultaneously managing non-financial risks as well as efforts to enhance corporate value for financial returns.

The strength standard of shotcrete in Korea is relatively lower than that in Europe where high-strength shotcrete has been developed and actively applied to the common practice, so it is hard to test a quality of high-strength shotcrete. In this study, field test was performed to find a solution improving the strength and a long-term durability on domestic shotcrete. In field test, a high-strength shotcrete was produced using high-quality additions and accelerators, and an effect of additions and accelerators was observed. In addition, quality test based on EFNARC was also performed. As a result of field test, a promotion ratio of early strength is 90~97% in case of using alkali-free accelerators, therefore, alkali-free accelerators had an effect on an increase of early strength on shotcrete. A compressive strength of shotcrete using Micro-silica fume was 45.2~55.8MPa and flexible strength was 5.01~6.66MPa, so a promotion ratio of strength was 37~79%, 17~61% respectively. It was showed that increment effect of strength by the silica fume replacement of 7.5~10% for cement mass was remarkable. As a result of test, it was possible to apply high-strength shotcrete to the domestic practice using high-quality additions such as Micro-silica fume and accelerators such as alkali-free.

Because of the insufficiency of ground space, the utilization of underground is getting more and more in these days. Moreover, underground space is being used not only buildings but multipurpose space for movement, storage and shopping. However, ground space has vital weakness for fire compared to ground space. Especially in case of underground shopping center, there are various stuffs to burn and poisonous gas can be exposed on this count when the space is burned. A large number of casualties can be also occurred from conflagration as underground space has closed structures that prevent rapid evacuation and access. Therefore, this research proposes the guidance methodology for evacuation from conflagration in large-sized underground facilities. In addition, suggested methodology uses high technology wireless sensor information from up-to-date ubiquitous sensor networks. Fire information collected by sensors is integrated with existing underground facilities information and this is sent to guidance systems by inducing process. In the end, this information is used for minimum time paths finding algorithm considering the passageway capacity and distance. Also, usefulness and inadequacies of proposed methodology is verified by a case study.

In this study, sequential mixing model (SMM) was proposed based on the Taylor's theory which can be summarized as the fact that longitudinal advection and transverse diffusion occur independently and then the balance between the longitudinal shear and transverse mixing maintains. The numerical simulation of the model were performed for cases of different mixing time and transverse velocity distribution, and the results were compared with the solutions of 1-D longitudinal dispersion model (1-D LDM) and 2-D advection-dispersion model (2-D ADM). As a result it was confirmed that SMM embodies the Taylor's theory well. By the comparison between SMM and 2-D ADM, the relationship between the mixing time and the transverse diffusion coefficient was evaluated, and thus SMM can integrate 2-D ADM model as well as 1-D LDM model and be an explanatory model which can represents the shear flow dispersion in a visible way. In this study, the predicting equation of the longitudinal dispersion coefficient was developed by fitting the simulation results of SMM to the solution of 1-D LDM. The verification of the proposed equation was performed by the application to the 38 sets of field data. The proposed equation can predict the longitudinal dispersion coefficient within reliable accuracy, especially for the river with small width-to-depth ratio.

Image processing technique in the outdoor environment is very sensitive, and it tends to lose a lot of accuracy when it rapidly changes by outdoor environment. Therefore, in order to calculate accurate traffic information using the traffic monitoring system, we must resolve removing shadow in transition time, Distortion by the vehicle headlights at night, noise of rain, snow, and fog, and occlusion. In the research, we developed a system to calibrate the amount of traffic, speed, and time occupancy by using image processing technique in a variety of outdoor environments change. This system were tested under outdoor environments at the Gonjiam test site, which is managed by Korea Institute of Construction Technology (www.kict.re.kr) for testing performance. We evaluated the performance of traffic information, volume counts, speed, and occupancy time, with 4 lanes (2 lanes are upstream and the rests are downstream) from the 16th to 18th December, 2008. The evaluation method performed as based on the standard data is a radar detection compared to calculated data using image processing technique. The System evaluation results showed that the amount of traffic, speed, and time occupancy in period (day, night, sunrise, sunset) are approximately 92-97% accuracy when these data compared to the standard data.

Die Gegenwart steht den Tatsachen der Gewalt gegenüber. Wesentlich destruktive Techniken können den kollektiven Tod des Menschen als Gattung produzieren. Die Destruktivität dieser Techniken ist durch Skeptizismus geistesgeschichtlich gerechtfertigt. Ebelings Fundamentalpragmatik ist Reflexionstheorie der widerstandsfähigen Vernunft, welche einer Sozialisierung derjenigen Gewalt widersteht, die in einer gegenwärtigen Aussicht auf universale Selbstdestruktion des Menschen Tod produziert. Selbstbewußtsein (Apperzeption) ist bei Kant Selbstbewußtsein in Gegenstandsbewußtsein. Mit kritischer Auslegung von Kant zeigt Heidegger endlich, daß der Tod der Selbstbeziehung des konkreten Daseins als des In-der-Welt-seins gehört. Aber seine existenziale Analytik berücksichtigt nur individuelles Dasein zum Tode und vernachlässigt die Allgemeinheit des menschlichen Todes bzw. die dem allgemeinen Untergang widerstehende Vernunft. Apel kritisiert ein solipsistisches Erbe von Kants Bewußtseinsphilosophie und präsentiert ein Argument der Letztbegründung zur Überwindung des Skeptizismus. Aber seine Transzendentalpragmatik vernachlässigt die Endlichkeit des menschen und zeigt ein Defizit der fundamentalpragmatischen Vereinigung der Vernunft und des Todes. Aufgrund des gegenwärtigen Todesbewußtseins, das Heideggers Todesdeutung transformiert, rekonstruiert Ebelings Existentialpragmatik Heideggers Dasein zu Existenzsubjekt. Seine Fundamentalpragmatik vollzieht diejenige Erstbegründung, die zwischen der existentialpragmatischen Endbegründung des Todes und der transzendentalpragmatischen Letztbegründung vermittelt, und damit bestimmt sie Vernunft als Widerstandsbewußtsein (das bewußte Sein) gegen den Tod. Also ist sie neue transzendentalphilosophische Bewußtseinsphilosophie, die mit der neuen Selbstbestimmung der Vernunft entwickelt wird.

When we divide Environmental Ethics education into the elements of 'knowledge - emotion - behavior', we need to focus on 'knowledge' at high school level. In general Moral Education, 'knowledge - emotion - behavior' is a circular link, but as Environmental Ethics is a matter of 'consciousness', it is desirable to instruct with the process of 'knowledge>emotion, behavior'. Teaching 'Consciousness on Nature' is not recommended at elementary or middle school level because it demands higher inference. On the contrary, considering the reality in high school it is not recommended to teach the necessity and method of recycling or to go field trip to the polluted area. Rather, it is better to inform the students of Environmental Ethics' viewpoints and let them know the ways of moral judgments. The view of nature in Orientalism is well explained through the Environmental Ethics' viewpoint. To explain the view of nature in Orientalism we should concentrate on the theory, not on the attitude of life. And we should rather compare the viewpoints of nature in Confucianism, Taoism and Buddhism respectively than explain in Orientalism all together. That is, if we compare with the viewpoints of Environmental Ethics and explain similarities & differences in Confucianism, Taoism and Buddhism, we can complement Environmental Ethics or present the third approach.

The present research is aimed at to examine the relationships between wisdom and age, also between wisdom and its psychological adaptation among middle and elder adults in Korea. Moreover, using data on 240 middle-aged and elder adults, the relationship between different aspects of wisdom and aging well were not only examined, but also explored age differences of wisdom through adulthood. The major findings from the study are summarized as follows. first, the wisdom scores of middle-aged and elder adults were significantly higher than those of young adults. While 'cognitive competency' and 'positive life attitude' factors had no significant differences. It means that 'cognitive competency' and 'positive life attitude' wisdom could be stable across adulthood. However, 'moderation and balance' and 'sympathetic interpersonal relationship' wisdom of elders were significantly higher than those of young adults. second, in middle and elder adults, Wisdom was found to be positively related with life satisfaction, well-being, death acceptance, experiences of positive emotion, generativity, ego integration, and positive life review. while on the other hand, contrast wisdom to be negatively related with depression, fear of death, perceived stress and experiences of negative emotion. The results from the study were examined by ecological validity of wisdom. Accordingly, a number of limitations and implications of the research were acknowledged.

Adolescence is the important period of experiencing primary social relations through family relations. Adolescent of grandparent-grandchildren family who are provided social welfare service, however, causes many psychological and social problems on account of the negative family relationship, so it is needed resilience in order to recover from those circumstances through easing their negative family relations. This study set self esteem, empathy and internal·external locus control as parameters in order to know how negative family relations of grandparent-grandchildren family could influence the resilience of adolescent, then tried to reveal the entire and synthetic causal relationship in paths of them. For this, we analyzed 492 cases of grandparent-grandchildren family adolescent, which had negative family relations. In this process, we used Amos 19.0, analyzed interrelation and path, and examined significance of type and statistical significance in direct-indirect effect between paths. As the analysis result, we proposed that the development of social welfare program and use of it centered on self-esteem, empathy and internal-external control to the family relations of grandparent-grandchildren family adolescents was a practical approaching task of social welfare for them.
