  • 액상화는 반복적인 전단력 혹은 강한 충격으로 인해 실트-모래로 구성된 미고결 퇴적층내 공극수압이 증가하여 전단강도를 상실함에 따라 미고결퇴적층이 액체처럼 거동하는 현상이다. 액상화는 미고결 퇴적층의 물리적 특성인 입도, 느슨함, 지하수위, 지층의 심도, 연령, 액상화 발달 유무 등과 밀접한 관련이 있으며 지표균열, 사태 및 연질퇴적변형 구조의 형성을 야기한다. 연질퇴적변형구조는 다양한 변형원인(trigger)에 의해 퇴적물의 전단강도가 감소함에 따라 퇴적물의 하중 등과 같은 변형동력(driving forces)이 발생하여 액상화, 요변성과 이에 수반된 유체화로 대표되는 변형기작(deformation mechanism)을 통해 형성된다. 이러한 변형구조는 퇴적작용이나 지진과 같은 지질학적 사건에 의해 발생하기 때문에 퇴적분지에서 발생하였던 지질학적 사건을 이해하는데 있어 중요한 역할을 한다. 이 뿐만 아니라 지진에 의하여 유발된 연질퇴적변형구조는 퇴적동시기성 구조운동을 이해할 수 있으며 지표파열을 수반하지 않는 피해 유발지진(> Mw 5.0)에 대한 고지진정보를 제공한다.

  • 단층은 지질학적 관점에서 국부적인 지구구조응력(tectonic stress)이 암반 내에 존재하는 어떤 면을 따라 파괴 분기값을 초과하는 경우에 발생하는 매우 큰 공간적 변이에 의한 파괴 면으로 정의된다. 이러한 단층의 수문지질학적 특성은 단층의 공간적인 분포와 간극의 연결성에 따라 변화된다. 단층의 형성이 단층 내의 간극의 생성과 파괴를 이끄는 과정이 포함될 때 단층을 따라 발생되는 변이와 간극의 변화 사이에 복잡한 관계가 존재한다. 본 연구에서는 단층의 기하학적 특성에 따라 변화되는 흐름 변화를 3차원 이산 균열망 모형을 통해 모의 및 분석을 수행하였다. 단층의 기하학적 특성에 대해 3가지 경우를 고려하였다. 첫 번째는 영역 중심에 위치한 폭이 매우 좁고 상대적으로 주위 암반보다 매우 높은 투수성을 가진 단층, 두 번째는 단층 주변에 손상지역(damaged zone)이 존재하는 경우 그리고 세 번째는 relay 구조를 가진 단층이다.

  • 기억은 과거보다 미래를 위한 정신적 활동이고, 기억을 복원 재생해야 할 책임은 현대를 살아가는 지식인에 있다. 이러한 맥락에서 도서관이 사회와 동행하려면 기억을 복원하고 사회적 역할과 기능을 분석하여 지역발전에 어떻게 기여하는지를 논증해야 한다. 본 연구는 공공도서관 지역발전 기여 사례를 배경정보와 문헌 사례 연구, 현장조사, 담당자 인터뷰를 통하여 개항도시 부산 인천 공공도서관의 지역경제 발전, 지역문화 재생 및 진작, 지역공동체 형성 등을 중심으로 지역발전 기여에 대하여 논증하였다. 그럼에도 경제적, 문화적, 지역공동체 형성의 측면에서 지역발전 기여도는 완전체가 될 수 없다. 도서관 자체의 역사지리 및 건축예술 측면, 지역주민의 인식 및 이용가치 측면을 반영하는 후속연구가 필요하다.

  • Companies and brands that practice sustainability pay attention to New Media due to its ability to build a sustainable relationship between companies and consumers. The need for research on specific roles, characteristics, and social media effects on eco-friendly advertising has had rapid growth in marketing programs for sustainable activities especially shown through social media. Information about sustainable fashion has spread to consumers through social media, and multifarious efforts have been made to attract the attention of youth. Despite the dramatic increase in eco-friendly marketing through social media as a part of sustainability, there is a lack of research on the major influences of emotional factors such as ad color and expression in social media. In this context, it is meaningful to identify relationships between emotional responses, advertising value and consumer behavior of sustainable fashion brands in Instagram and implement a suitable advertising type (color vs expression) for consumers. We used 366 responses for the final analysis. Data were analyzed by factor analysis, structural equation modeling using SPSS 18.0 and AMOS 18.0. The results of this study suggest that emotional responses, advertising value have a significant effect on the flow. This study expands on a previously limited research field by verifying consumer responses to image advertising on Instagram, rather than general sustainable fashion marketing. The study results also provide meaningful implications for a relation formation between customers and fashion brands vis-${\grave{a}}$-vis sustainable social media marketing.

  • 우리나라 법은 고연령자(高年齡者)를 지칭하는 용어로 여러 개를 혼용해 왔다. 본 연구는 법에서 고연령자는 누구이며, 고연령자를 어떤 사람으로 상정하고 어떻게 범주화하고 있는지에 관한 물음을 풀어보고, 고연령자를 지칭하는 명명이 갖는 의미를 비판적으로 고찰해보려고 한다. 2011년 10월 20일 현재 시행중인 법령과 1948년 7월 17일 대한민국헌법 제정 이후부터 현재까지 시행되었던 법령을 검토대상으로 삼았다. 연구 결과 다음과 같은 결론을 도출하였다. 법규정상에서 고연령자에 대한 명명은 노쇠자, 노인, 고령자, 노령자, 노약자 등 다양한 용어를 통해서 이루어져왔다. 이러한 명명이 고연령자 집단을 연령을 기준으로 구분함으로써 이루어진 것은 아니다. 법에서 가장 빈번하게 사용하고 있는 '노인'과 '고령자' 명칭을 살펴본 결과, 현재 우리사회의 고연령자에 대한 인식과 의미구성의 차이를 찾아볼 수 있었다. 사회적 보호 대상으로서 부정적 의미가 내포된 기표로서 '노인'이라는 명칭이 사용되고, 생산성을 지닌 존재로서의 기표는 상대적으로 중립적인 평가를 받는 '고령자'라는 명칭이 주로 사용되는 경향을 통해서 고연령자 집단에 대한 사회적 가치 부여를 내비친다고 할 수 있다.

  • Site-specific performance is always the real on-site work taking place at the site. Hence, it deals with the reality, in other words, the time of creation and formation. And it creates value and meaning through the interaction and continuous direct communication process between the performers, audience and the local residents. In this performance, the audience's status as the passive observer changes. They become the co-agent who actively lead and complete the performance through their own experience. We have examined the The Working Methods of Site-specific Performance and Aesthetics of Effect through four Korean performances ; Marie, An aesthetic experiment of site as the storyteller; Heterotopia and Urban Movement Research or Play: We Will Move Your Sofa, as performances which have Revealed history, politics, institution engraved in the site ; A Song of Mandala and Miracle, as a ritualistic site-specific performance at the historic site. Some remarks on Site-specific performance ; First, In Site-specific performance, the habitus peculiar to the stage art and the mode of reception are changed. Second, a new mode of theatrical communication requires creator and audience to have a sharp aesthetic sensibility and to change one's perceptual habit. Third, Site-specific performance can act as a demonstration for the viewpoints of political activism through what could be called a dramatic close-up effect. Fourth, Site-specific performance also has the risk of merely becoming an unfocused and scattered performance or degenerating into a pseudo-sightseeing. To avoid this, an in-depth study of the site and its socio-cultural context, and the clear motivation with which one is trying to reveal and tell from the site must be indispensable. As the co-agent, the audience should also be aware and think about what the given performance signifies today.

  • There is growing evidence for the dependence of Type Ia supernova (SN Ia) luminosities on the environments. The origin of this correlation, however, is under debate. In order to explore the physical origin of the trend in detail, we analyze SN Ia light-curves by combining a sample of 1231 SNe Ia over a wide redshift range (0.01 < z < 1.37) in various SN surveys and employing two independent light-curve fitters of SALT2 and MLCS2k2. Although SALT2 is the most widely used fitter in the SN community, MLCS2k2 has a novelty in the context of an investigation of the luminosity evolution of SNe Ia. For this reason we use both fitters and analyze them separately. We also determine a stellar mass and a star formation rate (SFR) for a sample of ~600 host galaxies. In addition, because recent low-redshift studies suggest that this dependence manifests itself most strongly when using the local SFR at the SN location, we introduce a new method to infer the local environments by restricting the SN Ia sample in globally star-forming host galaxies to a low-mass host galaxy subset (${\leq}10^{10}M_{\odot}$). We find that SNe Ia in low-mass and star-forming host galaxies are fainter than those in high-mass and passive hosts, after light-curve corrections. Especially, for the first time in host studies, we show that SNe Ia in locally star-forming environments are $0.081{\pm}0.018$ mag fainter ($4.5{\sigma}$) than those in locally passive environments from the sample including SNe at the high-redshift range. Considering the significant difference in the mean stellar population age between these environments, the result would suggest that the origin of the environmental dependence is the luminosity evolution of SNe Ia.

  • Developing countries face numerous challenges in the process of building science, technology, and research capacity; in particular, the formation and accumulation of skilled S&T workforce. The lack of organized and sustainable higher education options (Master and Doctoral programs), nonexistent or low-quality academic programs, and the absence of research-oriented study options are some of the strong contributors for talented students to emigrate to developed countries. At the same time, the consolidation of a global knowledge economy, the internationalization of higher education, and the competition to attract foreign talent in industrialized countries present challenges for underdeveloped nations to retain their already scarce skilled human resources. In this context, student mobility has been used as a policy mechanism to cope with S&T workforce shortages in S&T laggard nations. It has also enabled opportunities for international cooperation to play a key role. While significant literature has been devoted to studying the gains of developed nations with the arrival and potential migration of the mobilized students, few scholarly inquiries have addressed the benefits and losses experienced by their countries of origin. More importantly, limited research can be found on policy options and policy implications for developing countries to deal with the dilemmas presented by the brain-drain/brain-circulation debate. The goal of this article is to study empirical evidence of an international cooperation initiative for student mobility between the Republic of Korea and Guatemala (implemented during 2009-2015). The paper analyzes this particular international cooperation experience from the perspective of the different actors involved and attempts to draw policy implications and policy options for developing countries to deal with potential risks and gains derived from international mobility for their S&T capacity building.

  • Lack of knowledge and digital skills is a threat to the information security of the state and society, so the formation and development of organizational culture of information security is extremely important to manage this threat. The purpose of the article is to assess the state of information security of the state and society. The research methodology is based on a quantitative statistical analysis of the information security culture according to the EU-27 2019. The theoretical basis of the study is the theory of defense motivation (PMT), which involves predicting the individual negative consequences of certain events and the desire to minimize them, which determines the motive for protection. The results show the passive behavior of EU citizens in ensuring information security, which is confirmed by the low level of participation in trainings for the development of digital skills and mastery of basic or above basic overall digital skills 56% of the EU population with a deviation of 16%. High risks to information security in the context of damage to information assets, including software and databases, have been identified. Passive behavior of the population also involves the use of standard identification procedures when using the Internet (login, password, SMS). At the same time, 69% of EU citizens are aware of methods of tracking Internet activity and access control capabilities (denial of permission to use personal data, access to geographical location, profile or content on social networking sites or shared online storage, site security checks). Phishing and illegal acquisition of personal data are the biggest threats to EU citizens. It have been identified problems related to information security: restrictions on the purchase of products, Internet banking, provision of personal information, communication, etc. The practical value of this research is the possibility of applying the results in the development of programs of education, training and public awareness of security issues.

  • This study examined the apartment sale in lots system from 1960s to 1970s in Seoul from a historical perspective, with the focus on the concept and changes of pre-sale in lots system. By tracing back historical context and application of the system in that period through the analysis of the advertisements for apartment sale, we found out the hidden side of the apartment pre-sale in lots system from the public's point of view, and its impact and meaning on the formation of our current residential culture. In the 1960s and 1970s, the apartment sale in lots system based on the pre-sale in lots system formed strong seller's market and it has been the main reason for imposing the wrong residential awareness that led the public to recognize housing as a means of property growth. Even now, the current apartment sale in lots system remains to be a supplier-oriented one, and lots of people tend to regard housing as investment method. That is, this mechanism is not only still working but one of the fundamental causes of impoverishing our residential culture. It is necessary to reconsider the pre-sale in lots system and the apartment sale in lots system in relation to the public of housing.
