With the advent of the data economy, interest in using big data has increased, but conflicts with protecting personal information have been also steadily raised. In this regard, major countries are accelerating use of big data by exempting de-identified, pseudonymous personal information from protection. However, these policies have been made without the understanding that the economic value of personal information has been actually changing slowly. This paper presents the concept of 'collected information' and defines it as having public interest and therefore, not the exclusive property of the collector of such information. The paper shows the collected information has public interest in terms of personal information protection, connectivity, and universal service and public goods. It also specifies that the 'data governance' cannot be applied to the current data utilization framework that depends upon the holder's consent; rather, it raises the need to improve the practices of information provision consent or provide the beneficiary right of information use to the information holder in order to ensure the proper 'data governance' that will turn market failure into success.

This study purports to explore potential determinants of welfare attitudes toward universalism vs selectivism. For this purpose, literature review upon such subjects as definitions of universalism and selectivism and welfare attitudes has been done. The hierarchical regression analyses show several major results. First and foremost, the effects of those variables such as political orientation and attitudes toward free education and gratuitous child care, categorized as political-social stance were found to be significant. However, it was unexpected results that those variables which have been found signigicant in predicting welfare attitudes in previous literature, that is to say age, education and economic status especially were not to be found significant in predicting welfare attitudes toward universalism vs selectivism. There could be many underlying causes for this result including measurement errors, and this study strongly speculates that the division between universalism vs selectivism itself exists only both in purely conceptual level and in political rhetoric and therefore, universalism or selectivism as people's consistent and logical attitudes or consciousness may simply not exist at all.

최근 발생되고 있는 도시지역에서의 침수피해는 과거와는 다른 양상으로 발생되고 있으며, 이로 인해 많은 재산피해와 소중한 인명피해가 발생되고 있다. 도시지역의 침수피해는 다양한 원인에 의해 피해가 발생된다. 기후변화로 인해 발생되는 높은 강우강도의 집중호우로부터 도시 피복의 불투수화나 부족한 우수유출저감시설로 인한 침투비율의 감소에 따른 유출량의 증대, 짧은 도달시간으로 인한 빠른 하천수위의 상승, 빠른 하천수위의 상승으로 인해 발생되는 하수도의 만관에 따른 관수로화로 인한 역류 발생, 역류된 홍수류의 도시 내 저지대로의 유입, 최대 조위와 맞물려 발생되는 홍수류 배제의 어려움 등은 도시침수라는 결과를 제공하는 주요 원인으로 작동하고 있다. 이러한 현실은 도시지역에서의 침수대책의 수립에 있어 과거와는 다른 특정한 대책의 수립이 필요하다는 점을 시사해 주고 있다. 특히 도시침수를 발생시키는 주요 원인에 대한 개별적인 대책수립보다는 도시침수의 발생확률이 높은 지역에 대해서는 이러한 원인을 종합적으로 고려하여 이를 방어할 수 있는 효율적이고 실제적인 계획을 수립할 필요가 있다. 우리나라는 현재 행정안전부의 자연재해저감종합계획, 환경부의 특정하천유역치수계획 및 하수도정비기본계획을 기본으로 소하천정비기본계획, 하천기본계획 등 소관 부처를 달리하는 다양한 계획들을 수립하여 홍수로부터 귀중한 자산을 보호하려는 노력을 시행하고 있다. 이러한 계획들은 주로 홍수에 대비하고자 하는 특정 구조물의 설계를 중심으로 하고 있으며, 설계에는 항상 경제성의 개념이 수반되므로 설계용량을 초과하는 자연재해의 발생에 대해서도 홍수 발생에 대비하기 위해서는 홍수예보 및 재난대응체계의 운용과 같은 비구조물적인 대책도 매우 중요하게 활용되어야 한다. 이와 같은 현실에서 도시지역의 침수피해를 방지하기 위해서는 이제 과거와는 달리 개별법에 의해 수립되는 각종 계획들을 특정공간에 대해서 종합적으로 고찰하고 최적화하여 현실적이고 효율적인 하나의 계획으로 수립될 필요가 있으며, 하천을 중심으로 시행되고 있는 홍수예보와 유사한 도시침수예보와 같은 비구조물적 대책의 기술적 제고와 시행의 확산이 매우 시급한 실정이다. 본 연구에서는 최근 발의된 「도시하천유역 침수피해방지대책법(안)」의 경과와 이 법률에서 다루고 있는 주요 내용들을 살펴봄으로써 향후 우리나라가 지향해야 할 도시지역의 침수피해에 어떻게 대응해나가야 하는지에 관해 살펴보았다.

The defense environment is rapidly changing, such as nuclear and missile threats of North Korea, changes in war patterns, and a decrease in military service resources due to low birth rate. In order to actively respond to these changes, the Korean military is promoting Defense Innovation 4.0 and is trying to foster an army armed with high technology such as artificial intelligence (AI), big data analysis, etc. In this regard, we analyze the effectiveness of the radar-based AI scientific guard system applied by high technology for guard operations using Analytic Hierarchy Process (AHP). We first select evaluation factors that can assess the effectiveness of the scientific guard system, and analyze its relative importance. Each evaluation factor was selected by deriving a significant concept from operating principle and how they work, and by consulting experts on the correlation between each factor and effectiveness of the scientific guard system. We examine the relative effects of the radar-based AI scientific guard system and existing scientific guard system based on the importance of the evaluation factors.

Hydrogen isotopes can be categorized into light hydrogen, heavy hydrogen, and tritium based on the number of neutrons, each of which is used in specific fields. Specifically, deuterium is of interest in the electronics industry, nuclear energy industry, analytical technology industry, pharmaceutical industry, and telecommunications industry. Conventional methods such as cold distillation, thermal cycling absorption processes, Girdler sulfide processes, and water electrolysis have their own advantages and disadvantages, leading to the need for alternative technologies with high separation and energy efficiency. In this context, membrane-based hydrogen isotope separation is one of the promising solutions to reduce energy consumption. In this review, we will present the state-of-the-art in hydrogen isotope separation using membranes and their operating principles. The technology for separating hydrogen isotopes using membranes is just beginning to be conceptualized, and many challenges remain to be overcome. However, if achieved, the economic benefits are expected to be significant. We will discuss future research directions for this purpose.

In the performance analysis of a weapon system, the combat effectiveness is difficult to go beyond the conceptual level in the early stages of development. This is especially true in the case of new concept of weapon system that has never existed before. In this study, with the aim of analyzing the effectiveness of small personal guided weapons, the design of the warhead and the detonation test were carried out and the results were analyzed. Afterwards, trajectory of fragments were calculated from the results, and it is applied to the anti-personnel effectiveness logic which is a part of combat simulation tool. At the same time, delivery accuracy logic was constructed from Monte-Carlo simulation with 6-DOF trajectory model. Subsequent simulated experiments were conducted with test scenarios to confirm the simulation logic reflecting the results of the warhead detonation tests for verifying the simulation approach of weapon systems, and it was confirmed that the simulation logic incorporating the results of the warhead detonation tests functioned properly.

Network governance can be defined as collaborative process to develop a new socio-political order through civil society centered networking with government and market, and the term 'collaborative governance' can be used in a sense that the basis of governance is collaborative process. In particular, it can be stressed that collaborative governance between regions need double collaborative processes, that is, collaboration between local governments and collaboration between local government and local civil society within a region. Yet, the collaboration as a core element of collaborative governance should not be seen as a pure normativity presupposing confidence and reciprocity, but as a strategy based on competition and antagonism. The normativity implied in the concept of collaborative governance may not realized in actual process, and tends to be mobilized as a rationale for justifying neoliberal strategies. In order to overcome such limits of collaborative governance, the concept of collaborative governance should be reconstructed. This paper suggests that collaborative governance can be seen as hegemonic governing process in a Gramcian sense operating in the government plus civil society, and that, radicalizing Ostrom's concept, it also can be seen as a governing process producing polycentricity by self-regulating subjects. Finally, collaborative governance between regions needs expansion of material basis for economic complementarity and construction of infrastructure as well as a discursive process in order to enhance connectivity between them.

The issues on the representation of digital images, the uncanny is not considered aesthetically but must be overcome. It seems that the future of visual media using digital images, depends on the development and advancement of the digital technology. However, the Brothers Quay regarded as unique and experimental animators, focus their attention towards the past rather than the future. They trace back to the origin of the media, reproducing, manipulating, and representing gestures in oder to restore the shock and thrill delivered in film and animation. The Brothers Quay explore the uncanny of gestures through the mechanism of medium. They work in a wide range of genres, from animation, live action to dance film. The creaking spasms, which create the feeling that the movement does not belong to this world, and the strange gestures, reveals the flicker of the still projection and make audiences recognize gestures in the true meaning of the word. While they animate live actors and dead objects like automata, the hidden desires are revealed over screen. In this paper, focusing on the works of Brothers Quay, I tried to explore the uncanny of gesture based on Freud's and Jentsch' theory of uncanny.

The purpose of this thesis is to examine ontology of digital photo image based on a Simulacre concept of Gilles Deleuze & Jean Baudrillard. Traditionally, analog image follows the logic of reproduction with a similarity with original target. Therefore, visual reality of analog image is illuminated, interpreted, and described in a subjective viewpoint, but does not deviate from the interpreted reality. However, digital image does not exist physically but exists as information that is made of mathematical data, a digital algorithm. This digital image is that newness of every reproduction, that is, essence of subject 'once existing there' does not exist anymore, and does not instruct or reproduce an outside target. Therefore, digital image does not have the similarity and does not keep the index instruction ability anymore. It means that this digital image is converted into a virtual area, and this is not reproduction of already existing but display of not existing yet. This not-being of digital image changes understanding of reality, existence, and imagination. Now, dividing it into reality and imagination itself is meaningless, and this does not make digital image with technical improvement but is a new image that is basically completely different from existing image. Eventually, digital image of the day passes step to visualize an existent target, nonexistent things have been visualized, and reality operates virtually. It means that digital image does not reproduce our reality but reproduces other reality realistically. In other words, it is a virtual reproduction producing an image that is not related to a target, that is to say Simulacre. In the virtually simulated world, reality has an infinite possibility, and it is not a picture of the past and present and has a possibility as the infinite virtual that is not fixed, is infinitely mutable, and is not actualized yet.
