The production characteristics of activated carbon from waste walnut shell have been investigated by taking activation temperature, activation time, amount of activating agent, and kind of activating agent as the major influential factors. The adsorption capacity of the activated carbon which was produced using phosphoric acid as the activating agent increased with activation temperature and showed its greatest value at about $550^{\circ}C$. Yield for activated carbon was observed to decrease continuously as the activation temperature was raised. The optimal activation time for the highest adsorption capacity was found to be about 2 hr, and as the activation time increased the yield for activated carbon was showed to decrease continuously. The increase in the amount of activating agent resulted in the increase of the yield for activated carbon, however, excessive amount of activating agent deteriorated its adsorption capacity reversely. The variations of the microstructure of activated carbon observed by SEM with several influential factors, correlated very well with its changes in the adsorbability with the same factors and the kind of activating agent was found to play an important role in the determination of the adsorption capacity of activated carbon. To investigate the adsorption characteristics of the produced activated carbon, the adsorption reactions of $Cu^{2+}$ ion were examined using the produced activated carbon as the adsorbent. In general, the kinetics of the adsorption of $Cu^{2+}$ ion was observed to follow a 2nd-order reaction and the rate constant for adsorption reaction increased as the initial concentration of adsorbate was diminished. The equilibrium adsorption of $Cu^{2+}$ was explained well with Freundlich model and its adsorption reaction was found to be endothermic. The activation energy for adsorption was calculated to be 13.07 kcal/mol, which implied that the adsorption reaction was very irreversible, and several thermodynamic parameters of adsorption reaction were estimated using van't. Hoff equation and thermodynamic relationships.

An analysis of Yi Snag`s texts from the perspective of design enables it to find the diversity of visual expression in the texts and have a new understanding of his abstruse poetic texts that look to be difficult and complex, which will in turn excite the imagination of readers. This attempt is a task to be accomplished in design filed emphasizing creative imagination. Texts function as the image of a written language and thus is closely associated with the critical function of the modern design that stimulates the emotion of recipients. I could find a corelation in Yi Sang` poem during an attempt to understand his unique writing mode on the basis of an overall understanding of his literature and investigate the characteristics of his literature through a theoretical study on Cubis. I analogized the designical thoughts inherent in the texts on the basis of “AU MAGASIN DE NOUVEAUTES” in Yi Sang`s poem of “Architecture Infinite Cube” in which a shift of cubism that has greatly influenced the modern design. The purpose of this study is to identify the coexistence of texts and visual expression in an interdependent relationship and draw the meaning of a wide range of symbols and signs connoted in texts through an analysis of his texts in order to broaden my thoughts and have flexible thoughts crossing over between literature and art.

Objectives: To investigate the neurophysiological effect of acupuncture treatment on insomnia patients using quantitative electroencephalography (QEEG) and standardized Low Resolution Brain Electromagnetic Tomography method (sLORETA). Background: Insomnia is one of the commonly encountered symptoms in primary medical care. Recent studies of acupuncture for insomnia reported that the acupuncture groups showed significant improvements compared with the control groups. However, the neurophysiological mechanism of acupuncture in the treatment of insomnia has not been revealed and a few studies have measured the effect of acupuncture treatment using QEEG. Methods: Participants who had some problems in initiating or maintaining sleep, or had non-restorative sleep for more than 3 days a week and ISI scores above 8 and below 21 were treated by acupuncture for 2 weeks (3 times a week, total 6 times). We assessed the effectiveness of acupuncture for insomnia by the PSQI (Pittsburgh Sleep Quality Index) at baseline and at 2 weeks after the end of treatment (4th week). Also, we performed EEG and analysed the EEG data at baseline and at the end of treatment (2nd week) on the linked ears montage using the Neuroguide software program and sLORETA. Results: Thirty-two participants were enrolled and 2 participants dropped out because of personal reasons. Among the 30 participants, EEGs of 12 participants were included in the analysis of QEEG and sLORETA. Total score on the ISI and PSQI was significantly decreased after acupuncture treatment. The number of electrodes exceeding the range of 90% (±1.65) or 95% (±1.96) in the z scored absolute power of beta was significantly decreased after acupuncture treatment. There was no significant change in brain activation between pre- and post-acupuncture using sLORETA. Conclusions: The deviation of absolute power compared to the normative database was significantly decreased after acupuncture treatment in the alpha and beta ranges. Therefore, we suggest that acupuncture treatment for insomnia might be effective through the central nervous system especially in the brain. There are many limitations to drawing any conclusion. Further studies are needed in the future to overcome these limitations.

Amid the social instability and economic panic of the modern society in the 21st century, the anxiety, fear, and suppression that contemporaries feel are exposed to contradictory life of social policy pursuing welfare. Therefore, this researcher intended to analyze the poems of Yi Sang who experienced, under the Japanese Colonialism in the 1930s, the life similar to our contemporaries`, and thereby try to find images on the poems from the perspective of expressionism, one of movements in art history. Such a trial was aimed at having a right view on the current time in the social phenomenon causing changes in our visual culture, by exploring the events that were regarded as the past history. The imaginative unification process of visual expression appearing in anxiety and fear state is not able to be viewed simply as a subjective image of this contemporary researcher. Yi Sang`s Ogamdo was about aesthetic experience of the new and anxiety about appearance of something strange in the 1930s when, on one hand, his subjectivity of the rational self collapsed, and on the other hand, he was excessively exposed to new civilization. That feeling is similarly found in the current environments, such as the currently excessive development of industries, the remarkable development of science, food shortage, economic depression, natural disaster, infinite competition, depression of people of today, and their morbid stress. This work was intended to translate the text of Poem No. 1 in Ogamdo written by Yi Sang, and draw images from the perspective of expressionism in the fine arts. In doing so, it can help induce people to read poems actively through visual images of poems and thereby give them flexible thinking power of understanding literature and paintings, and diverse views on the way of looking into the present time.

The objective of this study is to review Sijo works carried on 'Chosun(朝鮮)' (an institutional magazine of the Japanese Colonial Government of Korea) and explore what such Sijo signified. In particular, attention was paid on 'Okdong-geosa(玉洞居士)' works that was carried on this magazine most frequently. It was hard to accurately confirm an identity of Okdong-geosa but it was presumed that such person was highly likely to have kept company with Ohcheong (吳晴) who was involved in editing of Chosun being entrusted by the Japanese Colonial Government of Korea. It was presumed that his works indirectly showed social trend during 1930s trying to have it to be incorporated into Bujeon-Gayo(不傳歌謠) of Japanese empire by showing a present passive Chosun being significantly discriminated from active independent characters. Through his works, he induced readers to lead their life based on pessimistic attitude. People living under colonial rule acutely needed this pessimistic cognition. Meanwhile, the works of reproducing Bujeon-Gayo as Sijo partly contributed to incorporate Bujeon-Gayo into local song of the Japanese empire. Bujeon-Gayo is a type of folk song imbued with local color and by reproducing this Bujeon-Gayo, Sijo was degraded as an art genre of imperial Japan. In addition, he highlighted activity, identity of national characters who ruled over Korean peninsula on the one hand and clearly contrasted it with passive, othernized present Chosun on the other. In other words, colonial logic was 'literaturized' by positively reproducing past Chosun history and negatively reproducing present Chosun situation. It is considered that editing direction of Chosun was in line with the fact that his works was frequently carried on Chosun. In other words, Sijo works carried on Chosun is considered to be provided as a means of partly contributing to thoroughly colonizing Chosun.

With development of scientific technology, modern society in the 21st century is changing more and more rapidly. Art also has extended its expression fields according to development of scientific technology and industry. In the rapidly changing modern society, the spread of visual images has been increasingly promoted, and modern people are exposed in the flood of various visual materials. The technology development in video media led the boundaries between popular culture and art to collapse. In this regard, the music video, as the cultural product, is a genre that begun to make a mark, as cultural media environments have become computer-oriented, as well a ubiquitous cultural form. Pop art is interdisciplinary art to be interpreted in various meanings of accepting environments, which have been constructed through development of industry and formation of consumer society in the mid 20th century. In spite of harsh criticism such as excessive jump on the commercialism, it has approached real world more positively, and actively and shown popular features in view of objet troupe with living patterns of modern civilization reflected, utilization of media images, mass duplication and production of images. In this research, various expressions of image duplication in pop art were examined, based on cases of Korean girl groups` music videos. The correlation between pop art, which has been just regarded as popular art, and pop art expressions in music videos, as well as analysis of their social influences, was also examined, according to principles of visual perception.

Films are comprehensive art that includes theater, music, literature, art, and dance. They are a video medium visually conveyed through images. The impact of films is gradually increasing as pop culture art of the modern society. Makeup, one of the elements that create these images of films, is an expressive way of creating external aspects of actors and actresses, such as cosmetic makeup, clothes, hair, etc., to a character that the screenplay expects. Makeup aims to realize images by analyzing a character’s situation in the time, age, and personality that cannot be manifested solely by actor’s imagination. It does not only change an actor’s appearance but also help him or her to immerse into the role and enhance the film’s level of completion. Studies of various character’s makeup were found from the precedent researches that were checked to proceed with this study. However, there are few studies of changes in the makeup that appear when a single actor performs multiple characters in a film. It is necessary to study some cases of the makeup that creates different images for a single actor through more delicate and specific analysis. Therefore, the purpose of this study is to analyze what difference three characters (King Gwang-hae, Ha-seon and Ha-seon who has become Gwang‑hae) performed by a single actor present through the makeup in the movie. As a result of the study, it was found that detailed areas such as beard thickness, skin tone, skin texture, eyebrows, eyes, lips, and hair decoration were different depending on the character image. In the future, when it is changed from video makeup to musical or theater makeup, it is expected to show a more maximized difference in makeup.

구도심 소규모학교에 전입한 초등교사의 경험과 조직사회화 전략에 관한 질적 사례 연구

이고은(Go Eun Lee),임선빈(Sunbin Lim) 한국교원교육학회 2024 한국교원교육연구 Vol.41 No.4

구도심 소규모학교는 학교 소재지의 특성과 학교 규모 차원에서 특수성을 지닌다. 구도심 소규모학교에 전입한 교사들은 상대적으로 급격한 환경적 차이를 경험하게 되며 이는 곧 조직사회화의 필요성으로 귀결된다. 따라서 구도심 소규모학교라는 새로운 조직에 진입한 교사들이 어떤 새로운 경험을 하게 되며, 어떤 전략을 활용하여 조직에 적응하는지 이해하고 이를 지원할 방안을 마련하는 것은 중요한 과제이다. 이러한 문제의식을 토대로 본 연구는 구도심 소규모학교에 전입하여 적응하는 교사들이 겪게 되는 경험과 그들이 활용하는 조직사회화 전략을 분석하기 위하여 심층면담 기법을 활용한 질적 사례연구를 실시하였다. 분석 결과, 다음과 같은 논의점을 제시하였다. 첫째, 구도심 소규모학교 전입 교사들은 소규모학교가 가지는 규모적 특성뿐만 아니라 구도심 지역이 가지는 환경적 특성으로 인해 이중적 어려움을 겪고 있었다. 둘째, 구도심 소규모학교에 전입한 교사들은 능동적으로 개인 차원의 조직사회화 전략을 활용하였으며 새로운 조직의 가치와 문화를 이해하고 수용하고자 하였다. 이상의 논의 결과를 바탕으로 구도심 소규모학교 교사들에게 요구되는 복합적 역할을 지원하기 위한 맞춤형 정책 마련, 낯선 환경으로 전입하는 경력 교사들에 대한 정책적 지원, 구도심 지역의 다양한 환경적 특성을 고려한 후속 연구의 필요성 등을 제언하였다. Considering the location and school size, small schools in old-urban area(SSOUA) have unique characteristics. Teachers transferring into SSOUA experience relatively dramatic changes in working condition, and this study explores their experience by adopting Organizational Socialization theory. It is important to understand what teachers experience and what strategies they use to after moving into the unusual organization, and how to support them to survive in strange environment. A qualitative case study using in-depth interviews is conducted in this study to analyze teachers’ experiences and organizational socialization strategies in primary SSOUA. The following discussion points are presented as a result of the analysis. First, teachers transferring into SSOUA faced dual challenges due to the environmental characteristics constructed by two aspects: 1) old-urban area and 2) unique organizational culture in small schools. Second, teachers relied on individual organizational socialization strategies to adapt in the new school organization. Based on the findings, several implications such as the need for personalized policies for SSOUA teachers, support for experienced teachers moving into SSOUA, and the need for follow-up research are proposed.
