With the recent reinforcement of emission standards, it is necessary to make efforts to reduce NOx from air pollutant-emitting workplaces. The NOx reduction method mainly used in industrial facilities is selective catalytic reduction (SCR), and the most commercial SCR catalyst is the ceramic honeycomb catalyst. This study was carried out to reduce the NOx emitted from steel plants by applying De-NOx catalyst coated on metallic monolith. The De-NOx catalyst was synthesized through the optimized coating technique, and the coated catalyst was uniformly and strongly adhered onto the surface of the metallic monolith according to the air jet erosion and bending test. Due to the good thermal conductivity of metallic monolith, the De-NOx catalyst coated on metallic monolith showed good De-NOx efficiency at low temperatures (200 ~ 250 ℃). In addition, the optimal amount of catalyst coating on the metallic monolith surface was confirmed for the design of an economical catalyst. Based on these results, the De-NOx catalyst of commercial grade size was tested in a semi-pilot De-NOx performance facility under a simulated gas similar to the exhaust gas emitted from a steel plant. Even at a low temperature (200 ℃), it showed excellent performance satisfying the emission standard (less than 60 ppm). Therefore, the De-NOx catalyst coated metallic monolith has good physical and chemical properties and showed a good De-NOx efficiency even with the minimum amount of catalyst. Additionally, it was possible to compact and downsize the SCR reactor through the application of a high-density cell. Therefore, we suggest that the proposed De-NOx catalyst coated metallic monolith may be a good alternative De-NOx catalyst for industrial uses such as steel plants, thermal power plants, incineration plants ships, and construction machinery.

Research has been conducted in various fields on a local fortress (eupseong) in the Joseon Dynasty, but the archaeological research on the prison (獄), which is part of the internal government, has not been conducted properly. Since the prison was first discovered in Gyeongju in 1997, there has been a necessity for research on the deployment and structure of the prison. This includes the office where jailers worked and had night duty and also the enclosure that keeps the prisoners inside. But the research came to a standstill because there was no comparative data. However, compared to the more recent findings of the Yeonil Prison and the Gonju Prison, we can identify that the structure was built during the early to the late Joseon Dynasty. King Sejong designed the standard prison blueprint called Anokdo (犴獄圖) in 1426 to manage prisoners nationwide and revised it once in 1439 to give better treatment during the winter and summer seasons. The Yeonil Prison operated from 1421 to 1743 and shows the structure of the prisons during the early to mid-Joseon period. It was very similar to the Gyeongju Prison on a smaller scale, which was operated until the late Joseon Dynasty with two main structures, one east and one west, and a circular fence. This structure was maintained even in the Gongju Prison during the late Joseon Dynasty, and it remains visible in photographs. The prison of the Joseon Dynasty had a circular fence with an estimated height of 3 meters and two buildings that separated male and female prisoners. The prison was divided into men on the east and women on the west with tile-roofed house structures that were difficult to escape. In front of the circular fence, there was an office with a thatched roof for the jailers and access to the prison was only possible through a double prison gate. The layout of the building reflects the improvements of the king's prison design made during Joseon Dynasty improving the environment of prisoners who are on trial and separating men and women in order to embody humanism.

In order to minimize damage to oil spill accidents in the ocean, it is essential to collect a spilled area as soon as possible. Thus satellite-based remote sensing is a powerful source to detect oil spills in the ocean. With the recent rapid increase in the number of available satellites, it has become possible to generate a status report of marine oil spills soon after the accident. In this study, the oil spill area was calculated using various satellite images for the Symphony oil spill accident that occurred off the coast of Qingdao Port, China, on April 27, 2021. In particular, improving the accuracy of oil spill area determination was applied using high-resolution commercial satellite images with a spatial resolution of 2m. Sentinel-1, Sentinel-2, LANDSAT-8, GEO-KOMPSAT-2B (GOCI-II) and Skysat satellite images were collected from April 27 to May 13, but five images were available considering the weather conditions. The spilled oil had spread northeastward, bound for coastal region of China. This trend was confirmed in the Skysat image and also similar to the movement prediction of oil particles from the accident location. From this result, the look-alike patch observed in the north area from the Sentinel-1A (2021.05.01) image was discriminated as a false alarm. Through the survey period, the spilled oil area tends to increase linearly after the accident. This study showed that high-resolution optical satellites can be used to calculate more accurately the distribution area of spilled oil and contribute to establishing efficient response strategies for oil spill accidents.

This article deals with the current status of investigation of the royal tombs of Baekje (Gongju Songsan-ri Tomb, Buyeo Neungsan-ri Tomb, Iksan Ssangneung) from the Japanese colonial period to the present. A review of the maintenance status is also conducted to see if the survey content was actually reflected in the restoration maintenance of the ruins. First, the structure scale and characteristics of the royal tombs of Baekje during the Woongjin and Sabi periods were identified by examining the survey content organized by period and feature. Through the recent re-excavation survey, it was confirmed that the results of the research during the Japanese colonial period were being verified. Next, before examining the maintenance status of the Baekje royal tombs, related content about maintenance of laws and regulations were extracted to establish the maintenance standards. It was confirmed that the most importance part of maintenance is 'maintenance of the original form' without compromising the authenticity of cultural properties. Based on these criteria, the maintenance status was reviewed. The main part of the burial tomb is located underground, so maintenance is mainly made around the tomb, which is the upper structure. However, most of the original burial mounds have been lost or damaged, so it is difficult to determine their original form. In fact, constant changes in the size and location of tombs from the Japanese colonial period to the present were confirmed in the Songsan-ri and Neungsan-ri tombs, meaning that the current maintenance status is problematic. On the other hand, in the case of Ssangneung, not only are the tombs relatively intact, but there are also few changes in the records, so it seems that maintenance was carried out that preserved the original form of the tombs. Therefore, the maintenance of tombs in the future should be based on 'maintaining the original form', but it is recommended that the 'education and utilization' plan be prepared after determining whether or not to restore the tomb and the degree of restoration.

According to the result of 2017 youth statistics, the first rank of the death cause of Korean youth is suicide for nine years. The recent study on factors affecting juvenile suicide presents: family factors; character and psychological factors; mental disease factors; suicide-triggering factors; school factors; and protection factors; and so on. What is required to the youth who are vulnerable to the confusion of identity and the adjustment of emotion or impulse is not only drug treatment or mental therapy but also the support of family or society where adolescents are encouraged to be introspective and form their identity in a healthy approach in the diverse humanistic philosophical dimension. This study is going to pay attention to the aesthetic existence of Kierkegaard who provided the foundation of human existential identity centered on three stages of existence. For this purpose, we attempt to search for the philosophical basis for the understanding of juvenile identity centered on the analysis of Kierkegaard's Either / Or Volume I (Entweder - Oder Teil I). Especially, we are going to attempt the understanding of aesthetics of youth through the analysis of three stages of desire (Begierde) suggested in Chapter 2 of this book. Herewith he suggests aesthetic existence through 'desire', and aesthetic existence as the desire again through three stages of 'dreaming ($tr{\ddot{a}}umend$)' desire, 'searching (suchend)' desire, and 'desiring (begehrend)' desire. Based on this analysis of three stages, we plan to graft the roots of sociological factors presented as the cause of youth's suicide onto the analysis of existential philosophy. Through this, we attempt to grope for the diagnostic and healing discourse which Kierkegaard's existential analysis can present in the formation and recognition of youth identity and disclose a factor of the emotion or the disorder of impulse adjustment as well as depression suggested as the main contributing factor of youth's suicide and search for philosophical discourse for the prevention of juvenile suicide.

The purpose of this study is to examine the meaning of learning methods for education to transmit the items designated as intangible cultural heritages focusing on Seoul-gut. Recently, as the Act on the Preservation and Promotion of Intangible Cultural Heritages was promulgated, 'the archetype' instead of 'the prototype' has become highlighted as a crucial axis for transmission. Although there are some controversies over the definition of the archetype among scholars, it is now possible for transmitters to make use of transformations rather freely being freed from strict orientation to the prototype to follow some fixed frame. Examining learning methods used in education to transmit mudang-gut, one of the items designated as intangible cultural heritages, however, this author has found that the prototype is still emphasized or in the center of learning instead. Presenting learning methods employed for Hwanghaedopyeongsansonoreum-gut of a national intangible cultural heritage, Namijanggunsadang-gut of Seoul Special City's intangible cultural heritage, and Bonghwasandodang-gut as examples, this researcher intends to reveal the reality. In the recent situation that education centering around academies is being widely spread to transmit mudang-gut, setting forth the designation of some of the items as intangible cultural heritages, they are publishing articles on newspaper as an advertisement to encourage learning about mudang-gut. Responding to the advertisement, there are more and more shamans intending to learn mudang-gut coming to the society for preserving items designated as intangible cultural heritages. They can, of course, perform mudang-gut on their own but come to learn it as there is no fixed or definite system for it. Even though the concept of the archetype was introduced, as now it is possible to learn the fixed frame through learning about the prototype regarding the item of mudang-gut as an intangible cultural heritage, those involved in shamanism are coming to it more and more. As transmitting the prototype rather deteriorated the liveliness of gut, those involved in shamanism are coming to it to learn about gut thinking that it is where they can learn the basic frame and also acquire more detailed knowledge about shamanism. Therefore, it is needed for the item of mudang-gut designated as an intangible cultural heritage to accept the aspects of change and develop new methods of education to transmit intangible cultural heritages.

The concept of 'monsters' have become popular, again, in recent times. A number of 'monster narratives' that discuss monsters such as zombies, humanoids, viruses, extraterrestrials, and serial killers have been made and re-made in popular media. Noting such an interesting cultural context, this article attempts, first, to find out some essential prototypical elements of a monster narrative and, second, to relate it with a catastrophic narrative. Correspondingly, the word 'monster' has been used as a conceptual prototype category that denies universal and clear definition, which makes it as one of the most widely used and familiar subjects of the use of metaphor. The prototypical meanings of various monster figures can be converged on a certain creature of being in this way held out as bizarre, curious, and abnormal. The monster figure that surpasses existing normality is also connected to 'abjection,' such as something that is cast aside from the body such as the bodily functions seen in its associated blood, tears, vomit, excrement, or semen, and so on. Nevertheless, both the monster figure and abjection produce disgust and horror in the minds of ordinary spectators or readers of media using this metaphor to heighten excitement for the viewers. The abject characteristic of the monster figure also has something in common with the posthuman figure, meaning to apply to a category of inhuman others who are held outside of the normal category of human beings. In the similar vein, it is natural that the most typical monster figures in our times are posthuman creatures embodied in such forms as seen with zombies, humanoids, cyborgs, robots, and so on. In short, the monster figure includes all of the creatures and beings that disarray normalized humanist categories and values. The monster narrative, in the same sense, is a type of story that tells about others outside modern, anthropocentric, male-centered, and Westernized categories of thought. It can be argued that a catastrophic narrative, a literary genre which depicts the world where a series of catastrophic events demolish the existing human civilization, ought to be seen as a typical modern-day monster narrative, because it also discounts and criticizes normalized humanist categories and values as is the result of the monster narrative. Going beyond the prevailing humanist realist narrative that are so familiar with existing values, the catastrophic narrative is not only a monster narrative per se, but also a monstrous narrative which disrupts and reinvents currently mainstream narratives and ways of thinking.

In this study we review the selected articles on elderly health and medical care published in the Journal of the Korea Gerontological Society (JKGS) in the last 40 years, and make suggestions for future research directions for gerontological health and medical care issues. Of all the 40 year publications from volume 1 (1980) to 38 (2017), we first examined the 30th anniversary review on the subject of gerontological nursing care and healthcare policies published in JKGS from 1980 (vol. 1, No. 1) to 2008 (vol. 28, No. 2), and reviewed recent 237 researches of this decade (out of all 655 articles from 2008, vol. 28, No. 3 to 2017, vol. 38, No. 4). We could find the following trends. Firstly, the analysis of the primary authors in the past 10 years revealed that those in public health, nursing and other health-related including physical education areas have dealt the subjects focusing on physical health while those in social welfare mostly on mental health. That is, physical health has been the prime subject of researches in the health and medical care area. Secondly, in the same period quantitative researches were accounted for 89.9%, which is similar to the trend of the first 30 years 81.5 %. On the other hand, qualitative studies were only 11 cases and the focus group interview were the most frequently used method comprising 33.3% among them. Thirdly, the non-experimental researches in the past 10 years comprise 65.4%, which was 82.7% in 1980 2008 period, indicating the increasing trend in experimental researches to deal with the issues in medical and healthcare fields. Lastly, the subjects of the researches were mostly the elders who are healthy, residents of city areas, or home dwellers, and 60% of them were over 65 years old in the past 10 years while the proportion was 42.7% in the previous review period. 81.6 % of the researches in the past 10 years was dealing both genders, slightly decreased trend compared to 88.5% of the previous review period. This study reveals that the researches in non-experimental physical health remains the main stream of JKGS despite the efforts by some researchers to diversify the methods and subjects. Systematic and in-depth researches employing multidisciplinary, qualitative, longitudinal and meta-analytical approaches are called for to guide the gerontolgical health issues with preventive and proactive perspectives.

Since 2016, public and political interest on basic income has been increased beyond academic interest. The recent debate on basic income has expanded on issues regarding to the concrete implementation of basic income moving further than the debate on conception of the basic income in the abstract level. This study examines major critiques of basic income which was raised from social policy area and makes a counter-argument on these critiques. Major points summarized as follows. First, the problem of jobs and social insurance exclusion is not serious enough to call for basic income. Second, existing social security systems will be crowded out by excessive financial burden if basic income is introduced. Third, policies to cultivate citizens' capacities to cope with a technological change should be given priority over basic income. This study disputes these critiques by counter arguing four points. First, it is necessary to reconstruct welfare state based on basic income, given the labor market changes, such as long-term trend of employment change, newly emerging employment of platform companies, and inconsistency of platform labor and social insurance. Second, hypothesis of crowding-out effect on social security system is just a criticism that can be applied to the basic income initiative of the right-wing. Also, it is unable to find a logical basis or evidence of this hypothesis from the historical process of welfare state development or previous studies. Third, it is necessary to discuss how to reconfigure existing social security system and basic income which are complementary to each other and also have consistency with labor market as a configuration, not as a matter of choosing between basic income and social security system. Fourth, de-laborization does not mean a refusal to labor but a free choice, and the basic principle of social security is not needs but right. In conclusion, in order to develop more productive debate on basic income, it requires more sophisticated discussion and criticism from the point of view of the distributive justice; the debate on the sustainability of social insurance-centered welfare states; and debates on the political realization of basic income.

The study of Freud's Moses and the background of the establishment of monotheism has become a subject of attention in the new atmosphere of the spreading of political theology and the recent rediscovery of Egyptology. This paper examines the publishing background and intentions of Freud's last book, Moses and Monotheism. And it will emphasize the fact that the Moses-Egyptian theory and his criticism of monotheism hid political theological intentions to prevent the spread of anti-Semitism in Nazi Germany. According to the Egyptologist Jan Assmann, there is a difference in that Moses' Judaism is monotheism, but Akhenaten's Aton-religion is a cosmotheism, and while Freud emphasizes Moses the 'historical figure' of that name, Assmann refers to Moses as a 'mnemohistorical figure.' Just as Freud said that the source of Jewish hatred is in Moses himself who established monotheism, Assmann argues also, monotheism is based on the so-called "Mosaic distinction" that distinguishes between true religion and false religion, thus it is possible to dismantle oppression and violence through the abolition of the Mosaic distinction. Assmann estimates that Freud had a clear stance to stop the spread of anti-Semitism as "the most explicit opponent of the Mosaic distinction." While anti-Semitic hatred spread to Christians in the Nazi era, Freud regards the real founder of Christianity, a jew Paul, as both a "Judaism destroyer" and a "successor to Judaism." At this point, Taubes began to see Paul's theology from a political theological point of view, and Assmann succeeded it. The "historical Moses" described by Freud are not "Prophet Moses" but "Moses as lawmaker and political reformer", and Jewish hatred has arisen in his distinction. Thus, Freud's monotheistic criticism as "disintegration by historical reduction"(Nietzsche) has political theological power. Just as Taubes interpreted Paul as a political theologian, Assmann found political theological elements in Freud's criticism of monotheism.
