Synthetic natural gas was producd by the reaction of carbon monoxide and hydrogen via methanation. Ni-Co bimetallic catalyst supported on $Al_2O_3$ for methanation was prepared using deposition-precipitation method. For the comparison, Ni, Co monometallic catalyst was prepared using the same method. The prepared catalysts were characterized by TEM, XRD and TPR and applied to methanation reaction. The catalysts prepared using deposition-precipitation method showed the high metal dispersion. The activity of Ni-Co bimetallic catalyst was higher than that of Ni, Co monometallic catalyst. TPR measurements indicated that Ni-Co bimetallic catalyst had more active hydrogen species than Ni, Co monometallic catalyst due to the synergetic effect in the presence of Ni and Co.

The purpose of this study was to investigate the meaning of the extracurricular activities in the early childhood education institutions because the discussions and the discrepancy between theoretical viewpoint and reality are gradually expanded. For this purpose, the classes of three early childhood education institutes were observed, and interviews with the instructors were conducted where extracurricular activities programs were implemented. The meanings of extracurricular activities in the early childhood education institutes were 'coexistence of newness and pleasure', 'meaning as learning', 'diverse teaching media experience' and 'inevitable limit' in the reality of formal lessons and other situations. Based on the results of this study, it is necessary to make comprehensive and complementary approaches between the formal curriculum and extracurricular activities for the future high quality extracurricular activity education. Continuous training and education of the instructor are required for better extracurricular activities.

This study investigates factors that affect the transformation of multiplex tie into one specific type of relationship - competitive relationship. In particular, this study argues that the lower technological distance or gap of technological competency, the higher the chances are for the multiplex tie to become a competitive tie. In addition, technological characteristics of the firms are also found to affect the multiplex tie's transformation into the competitive tie. To study this phenomena, this study uses both quantitative analysis and case study method. This study is an exploratory attempt to find factors relevant to change multiplex ties into competition, contributing to the literature of multiplex ties by identifying technological variables that affect the transformation of such ties. This study also contributes to practices by providing the guidance on what strategies firms should implement in complex situations such as multiplex ties.

If traditional Korean villages or residential districts have formed a community on the ground of coexisting with nature, there is a different historical development process in which many European cities have created residences for multi households on the basis of roads and blocks in fortresses. Along with the modernization of society together with large-scale housing supply, the urban landscape of series of large apartment complexes has become universal views of our urban structure; thus, the viewpoint that small and medium-sized block-based collective housing, which are more common urban structures in European cities can be linked to the improvement of urbanity and neighborship is examined. Through the process, the possibility of expanding collective housing supply based on small and medium-sized blocks as an alternative method other than complex-type apartments based on superblock, I would like to make meaningful in terms of how we can change the fundamental mutual relationship with our lifestyle and the tangible change of collective housing types which has large impact on our lives.

Philip Roth rejects the narrative unity and singularity of the traditional novel and creates instead a multi-levelled, fragmentary, and repetitive narrative. It is not easy to distinguish fact from fiction in The Plot Against America. As an entertaining and creative work of the postmodern historiographic metafiction, Philip Roth's The Plot Against America interrogates the existence of historically verifiable facts, the validity of authentic and official version of history, and reexamines the narrative conventions of history writing. The aim of this paper is to examine Roth's narrative experiment or 'thought experiment' and to explore the intention of creating alternative history in The Plot Against America. Roth does a 'thought experiment' in The Plot Against America. In this cautionary "what if" political fable, Roth hypothesizes that in 1940 aviation hero Charles Lindbergh, an ardent isolationist who was sympathetic to Hiltler, won the presidency. Jewish communities are stunned and terrified as America flirts with fascism and anti-semitism. Reimagining his children-with considerable fact mixed in with the fiction-Roth narrates an alternative history that has an unsettling plausibility. Roth has constructed a brilliantly telling and disturbing historical prism by which to refract the American psyche as it pertain to the discord of individual, race, history in The Plot Against America. Roth analyzes the life of individual in a historic space, the situation of anti-semitism in world of invisible order, racial conflict between black and white in world of visible order, and the darkest side of national power in this work. Roth's stories argue for the equality of various cultures grounded on the common notion of humanity, for an ethic of mutual respect, and for the peaceful resolution of conflicts.

식민지하 동남아 천년왕국 운동에 대한 오늘날의 해석들은 그 주체인 농민들을 식민주의를 개념화하고 저항하는 동기와 조건 그리고 상징을 제공하는 토착 지식의 전수자로 간주한다. 종말론과 저항에 대한 관심의 대부분은 농민연구나 지역연구 학자들로부터 유래하며, 이들은 봉기에 대한 과거의 묘사들이 토착의 정신세계를 간과했거나 국가이념을 저항세력들의 결집원리로 과대 포장한 것에 주의를 기울인다. 천년왕국 봉기에 관한 글들에서 제공하는 해석들은 동남아 신념 체계에 관한 독립적인 관점을 제공할 뿐만 아니라, 인식론적 측면에서 식민지국가들을 이와 같은 전통에서 단절시키고 있다. 영국 식민지하에서 최대의 농민반란인 서야쌍 봉기(1930-1932)는 오늘날 이와 같은 천년왕국 운동의 정수를 보여주는 사례로 간주된다. 학자들은 수천 명의 농민들로 하여금 버마인의 권위를 되찾고, 불교를 회복시키며, 식민통치로 인해 낳은 사회-경제적 부조리를 일소시킬 그들의 왕으로 믿게 만든 한 농부의 흥미로운 이야기를 묘사하고 있다. 일련의 반란이 미신에 의해 추동되었다고 간주한 식민지 관찰자들과는 달리 이후의 역사가들은 그 반란이 불교를 재건하고 태평성대로 인도할 미래부처인 미륵불의 현신에 대한 믿음의 표현이라고 해석했다. 이러한 학자들에게 서야쌍 봉기는 어떻게 동남아 사람들의 감수성이 식민지의 사회-경제적 압력 속에서도 지속되었으며, 상좌불교의 예언이 토착의 문화적 토양에 얼마나 깊이 내재해 있는지를 말해주는 사례였다. 경험적 관점에서 본 글은 서야쌍 봉기의 근원을 재해석함으로써 천년왕국 봉기에 관한 글들이 대부분 식민지적 문서화 작업과 종교를 과장되고 세속화된 화술로 믿게 하려고 지역연구자들의 산물임을 밝히고 있다. 개념적 관점에서 본고는 버마에서 일어난 천년왕국 운동의 역사적 구성에 대한 식민주의의 역할을 보다 면밀히 관찰하였다. 또한 식민지법, 학문, 그리고 식민지하 버마 농촌에서 발생한 종교적 저항에 대한 우리들의 이해를 상호 연결하는 인식론적 관계를 탐구했다. 그리하여 본고는 천년왕국 해석이 이 시기에 공존했던 다른 유형의 불교정치적 형태를 어떻게 왜곡했는가를 밝히고 있다.

Objectives：As increasing number of new antidepressants have been being introduced in clinical practice, pharmacological understanding has been broadened. These changes mandate new information and theories to be incorporated into the treatment process of children with depressive disorders. In light of newly coming knowledge, this review intended to recapitulate the characteristics of new antidepressants and to consider the pivotal issues to develope guidelines for the treatment of depression in childhood and adolescence. Methods：Searching the Pub-Med online database for the articles with the key words of 'new', 'antidepressants' and 'children' ninety-seven headings of review articles were obtained. The author selected the articles of pertinent subjects in terms of either treatment guideline or psychopharmacology of new antidepressants. When required, articles about the clinical effectiveness of individual antidepressants were separatedly searched. In addition, the safety information of new antidepressants was acquired by browsing the official sites of the United States Food and Drugs Administration and Department of Health and Human Services. Results：1) For the clinical course, treatment phase, and treatment outcome, the reviews or treatment guidelines adopted the information from adult treatment guidelines. 2) Systematic and critical reviews unambiguously concluded that selective serotonin reuptake inhibitors(SSRIs) excelled tricyclic antidepressants( TCAs) for both efficacy and side effect profiles, and were recommend for the first-line choice for the treatment of children with depressive disorders. 3) New antidepressants generally lacked treatment experiences and randomized controlled clinical trials. 4) SSRIs and other new antidepressants, when used together, might result in pharmacokinetic and/or pharmacodynamic drug-to-drug interaction. 5) The difference of the clinical effectiveness of antidepressants between children and adults should be addressed from developmental aspects, which required further evidence. Conclusion：Treatment guidelines for the pharmacological treatment of childhood and adolescence depression could be constructed on the basis of clinical trial findings and practical experiences. Treatment guidelines are to best serve as the frame of reference for a clinician to make reasonable decisions for a particular therapeutic situation. In order to fulfill this role, guidelines should be updated as soon as new research data become available.

Landscape around a settlement is not only a natural object, but also a matters of the man in the co-relation with his environment. Man perceives the landscape rational or sensible. Then it changes into the substance for him and influences him: as we see often in the folklore, that is of importance in the mind. Man reacts against his surroundings deceidedly, selfassurd or commonly, and uses sometimes the landscape to the elements for realization, physical or symbolical. Out of one character of korean villages, adaption to the circumstances, we can notice also its inner image, the reflection of the mind. Seeing and perceiving the environment emotional or reasonable and, reflecting and descreibing the inner self on the space. Here, the landscape and the nature are matter of the man, a scale for his ethical estimation or a mailer of the realization his mind. It is difficult, but important, such a immanent picture in(or of) the landscape to find. This is a preliminary study in such a way.

Approaches to spatial analysis differ from the type of spatial objects to be treated. Especially, in here, the case where two spatial data sets coexist is considered. The goal of such case lies on detecting a subset of spatial objects out of a large set that affects the distribution of the other object. However, it is not easy to extract a subset from a large set by visualization just with the help of GIS since huge amount of data are provided nowadays. In this research, therefore, relationship between two different spatial data are analyzed by quantitative measure in the case study of marketing geography. A purchase history data of a small retail store and the location of its competitors are given as source data for the analysis. The goal of analysis from the aspect of this case study is to extract strong competitors of the store that affects the sales amount of the store among many competitors. With the result, therefore, it is expected that market area pattern and competitive power of stores under micro scale retail environment would be understood by quantitative measure.
