  • Global warming becomes a serious issue that poses subsidiary issues like a sea level rise or a capricious climate over the world. Because of severe heat-wave of the summer in Korea in 2016, a big attention has been focused on urban heat island since then. Not just about heat-wave itself, many researches have been concentrated on how to adapt in this trendy warming climate and weather in a small scope. A big part of existing studies is mitigating "Urban Heat Island effect" and that is because of huge impervious surface in urban area where highly populated areas do diverse activities. It is a serious problem that this thermal context has a high possibility causing mortality by heat vulnerability. However, there have been many articles of a green infrastructures' cooling impact in summer. This research pays attention to measure cooling effect of a street planting considering urban canyon and type of green infrastructures in neighborhood scale. This quantitative approach was proceeded by ENVI-met simulation with a spatial scope of a commercial block in Seoul, Korea. We found the dense double-row planting is more sensitive to change in temperature than that of the single-row. Among the double-row planting scenarios, shrubs which have narrow space between the plant and the land surface were found to store heat inside during the daytime and prevent emitting heat so as to have a higher temperature at night. The quantifying an amount of vegetated spaces' cooling effect research is expected to contribute to a study of the cost and benefit for the planting scenarios' assessment in the future.

  • This study examines the types of strategic alliances formed between terrestrial broadcasters and content start-ups, their resource inter-dependence and the dynamic evolution of their relationship through a case study of KBS Labs, a strategic alliance between KBS and content start-ups. Mergers, acquisitions and strategic alliances sought by large media companies or strategic alliances made only between disparate providers in broadcasting and telecommunications industries are now actively pursued by traditional media and start-ups. The alliances between traditional media and start-ups are beneficial to both parties: traditional media can quickly implement start-ups' innovative ideas and business models and start-ups can tap into not only vast amounts of content being created by or in the archives of traditional media but also their capital, office space and reputation. Therefore, the case study of KBS Labs will help draw out important implications for motivating strategic alliances between traditional media and start-ups. To this end, the resource-based view and the evolutionary theory of the firm are adopted to explore the characteristics and development process of the KBS Labs business.

  • Archival science is prior to explore meaning and role of record management in given environments rather than developing record management methodology. Electronic record environments don't merely mean to exchange record management medium from paper to digital. The most important point exploring in electronic record environments is not management skills or methods, but meaning of records and role of record management in contemporary society. All these days, however, the theories and methodologies has been developed focusing on written records and public records mainly in the deep-rooted influence of positivism. In such situations, the discussions of social memories can explore meanings and roles of record management in pluralistic society. Meanwhile, many articles in archival science has been widespread recognition that records will soon be just memories in terms of objective and neutral evidence. In recently, however, conviction on objectivity and neutrality of records has broken down by the influence of postmodernism on archival science. Therefore this article intends to explore the relationship between record and memory and to argue the roles of archival science for building social memories.

Expression Analysis of OsCPK11 by ND0001 oscpk11 Mutants of Oryza sativa L. under Salt, Cold and Drought Stress Conditions (염분, 저온 및 가뭄 스트레스 조건에서 벼 ND0001 oscpk11 돌연변이체의 OsCPK11 발현 분석)

  • Calcium-dependent protein kinases (CDPKs) are known to be involved in regulating plant responses to abiotic stresses such as salinity, cold temperature and dehydration,. Although CDPKs constitute a large multigene family consisting of 31 genes in rice, only a few rice CDPKs' functions have been identified. Therefore, in order to elucidate the functions of OsCPK11 in rice, this study was intended to focus on the expression pattern analysis of OsCPK11 in wild type and ND0001 oscpk11 mutant plants under these abiotic stresses. For the salt, cold and drought stress treatment, seedlings were exposed to 200 mM NaCl, 4℃ and 20% PEG 6,000, respectively. RT-PCR and quantitative real-time PCR were performed to determine the expression patterns of OsCPK11 in wild type and ND0001 mutant plants. RT-PCR results showed that OsCPK11 transcripts in the wild type and heterozygous mutant were detected, but not in the homozygous mutant. Real-time PCR results showed that relative expression of OsCPK11 of wild type plants was increased and reached to the highest level at 24 hr, at 6 hr and at 24 hr under salt, cold and drought stress conditions, respectively. Relative expression of OsCPK11 of ND0001 homozygous plant was significantly reduced compared to that of wild type. These results suggested that oscpk11 homozygous mutant knocks out OsCPK11 and OsCPK11 might be involved in salt, cold and drought stress signaling by regulating its gene expression.

  • Phenylketonuria is the most prevalent disorder caused by an inborn error in aminoacid metabolism. It results from mutations in the phenylalanine hydroxylase (PAH) gene. If untreated or late treated, results in profound and irreversible mental disability. Newborn screening test identify patients with phenylketouria. The early initiation of a phenylalanine restricted diet very soon prevents most of the neuropsychiatric complications. However, the diet therapy is difficult to maintain and compliance is poor, especially in adolescents and adulthood. Since 2015, American Medical College of Medical Genetics and Genomics (ACMG) recommended more strong restrictive diet therapy for target blood level of phenylalanine (<360 umol/L). For over four decades the only treatment was a very restrictive low phenylalanine diet. This changed in 2007 with the approval of cofactor therapy (Tetrahydrobiopterin, BH4) which is effective in up to 30% of patients. Data from controlled clinical trials with sapropterin dihydrochloride indicate a similar occurrence of all-cause adverse events with this treatment and placebo. Large neutral aminoacids (LNAA) competes with phenylalanine for transport across the blood-brain-barrier and have a beneficial effect on executive functioning. A new therapy has just been approved that can be effective in most patients with PAH deficiency regardless of their degree of enzyme deficiency or the severity of their phenotype. Phenylalanine ammonia lyase (PAL-PEG) was approved in the USA by FDA in May of 2018 for adult patients with uncontrolled blood phenylalanine concentrations on current treatment. Nucleic acid therapy (therapeutic mRNA or gene therapy) is likely to provide longer term solutions with few side effects.

  • This paper is an attempt to examine historical drama which change rapidly in the manner of seeing history. Historical records are treated differently unlike in the field of modern history. Now the distinction between historical facts and fictions becomes no longer important. This change is affected by micro history, new cultural history, or post-modern history. History and narrative become interactive each other. In this respect they are no more historical drama. by Han Areum (director Suh Jae-hyung) represents this new trends. Of course, it doesn't suddenly pop up in 2005. It began in by Lee Yoon-Taek, was reinforced in by Kim Tae-Woong, and bloomed in . I intended to search important features of by following three. First is the interest about unimportant persons such as a maid of honor, an eunuch. In , they are the main characters. The author described much about those trivial people revealing the truth in different way of the existence. Second is the way of calling a past. In this piece, the past is not continuous. The past always appears at the stage by the present in the form of split which is imagination, recollection, revival. Third is a mixing genre. Comics, melodrama, and thrillers are all together in . This is a similar phenomenon to historical novel and movie of new trend. Strictly speaking, this piece isn't a history thriller. The accident of lost prince doesn't be treated importantly and the result isn't clear either. In this piece, detective genre is used for a symbol showing that writer pursuits the history, not the event. This represents well the characters of new historical drama because how historical facts are carefully recreated and constructed are important. It's enough to show the possibility to mix genre through comics and melodrama.

  • Nog-Moon Yim Seong-Joo(녹문 임성주) is a philosopher of late Choseon Dynasty of the 18th Century. He concluded that the debates between the school of Ho and that of Rack originated from the seclusion of Li(理) and Ki(氣), and theorized the new Li and Ki theory according to his own perspective. The prime point of Nog-Moon's Philosophy is said to be Li-Ki dongshil(理氣同實), Mind and Nature ilchi(心性一致) ; he proves his prime potints based on his pure and clean Ki substance. Thus Li-Ki is reduced to monism from dualism, and Mind-Nature(心 性) is reduced to mind. Since the basis of the existence of Mind is Ki(氣), Nog-moon's theory of Substance is concluded to be Ki-monism. Nog-Moon presents his great philosophy of Ki monism suggested by Jeong Myeong-Do's monistic methodology; he explains the universality of Substance and the diversity of Phenomenon with the logical structure of ilwonbunsu(一原分殊). The characteristics of Nog-Moon's philosophy is that ilwon(一原) and bunsu(分殊) are bonnyeon(本然) identical, which means Substance and Function(體用) are identical, or bonmalilchi(本末一致). It means Mind and Nature are bonnyeon(本然) identical, Ki and Mind and Nature are identical. With the expression of seongrihak (性理學) Gijil(氣質) is not different from bonnyeon(本然). Therefore 1 define the philosophy of Nog-Moon had been built on the context of a sage.

  • In relation to body conception, the introduction of western medicine to Joseon Korea started off some points in disputes: the one was whether the western anatomy was positive or not, the other was whether the cognition was ruled by heart or brain. In the long run of these disputes, that who had clarified the change of body conception was Choi Han Kee. His new conception of body was characterized as follow: on the one hand, it emphasized the mechanical conception of body; on the other hand, it emphasized the cognitive ability of body. But that his conception of body had obscure points: that is, its mechanical conception was intervened by chi(神氣), and his doctrine of cognition searched for the origin of cognition in balance of chi of the body. He had set up this conception of body by the combination of western medicine and chi, but the combination did not seem to be perfect. This point had appeared again in his conception of physics that he thought the basis of medicine. He had pursed the combination of chemical element and chi, but it could not be accomplished successfully unless he had abandoned the organicist conception of chi. In conclusion, his new conception of body was not free from the suspicion of a incomplete tentative construction.

  • The purpose of this study is to find out the factors that affect the 'public librarian servant's' Collective Self-Esteem (CSE) in Korean relation-oriented collectivism. The research was organized into a research model by setting up a hypothesis on the impact relationship the between the group Collective self-esteem, the work environment factors and cognition of Superior institution of the Public librarian servant. The relevant data collection was conducted for public librarian servant working in public libraries nationwide through the method of survey. From April 3, 2020 to May 14, 2020, it was conducted for Public Librarian Servant in public libraries nationwide with Civil Service System, Office of Education, Ministry of Culture·Sports and Tourism based on responses for 301 Public Librarian Servant from 559 institution. According to the analysis, the cognition of the superior institution of Public Librarian Servant influences the cognition of Collective Self-Esteem among the sub-factors of Collective - Self - Esteem of Collective Self-Esteem. This study is meaningful in that 'Public Librarian Servant' who was treated as an individual entity in the study of Library and Information Science study, as being has relationship with various groups and is dealt with multi-dimensionally in Korean relation-oriented collectivism culture. Research suggests that when Public Librarian Servant exist as one of the subordinate organizations to vast Civil service system, it suggest that Public Librarian Servants should find out a balance for improve their relatively low social values.

  • The year 2021 is a monumental year for the history of Korean cinema that inferiority of the sci-fi genre, by the appearance of two sci-fi blockbuster films- produced by Netflix and produced by TVing-at the same time. Coincidentally, both of movies are sci-fi films which appear post-human such as robot and clone. As can be seen in 『Frankenstein』 story, the progenitor of science fictions, the mankind have imagined beings similar to humen or post-human who are another human being for a long time. deals with the unusual subject matter of a space scavenger and a space janitor, and the main character is a robot that very familiar with human. is the story of a man who lives for a limited life protects and accompanies a clone named Seobok who was created as a test subject. This film deals with the philosophical themes like death and eternal life through the existential concerns of two characters. use Korean Shinpa -Korean specific senimental code-sentiment on narrative, and has the character of a road movie set in Korea's geographical space.
