본 연구는 아시아 각국 중 활발히 경관계획이 수립되고 있는 일본과 우리나라를 대상으로 경관데이터베이스를 구축함과 동시에 경관제도를 비교하고 분석함을 목적으로 했다. 경관법 제정후의 우리나라의 경관법(2008.3)과 일본의 경관법(2004.6) 그리고 그 조례와 시행사례를 한국과 일본을 대상으로 비교하여 특징을 파악했다. 일본에서는 2010년 12월 1일 현재 472개의 지자체가 경관행정단체이며 우리나라는 2010년 3월 1일 현재 83지자체가 경관행정단체임을 알 수있었다. 한일 양국의 경관법은 전체적으로 보면 유사한 구조로 구성되어 있으나 우리나라의 경우 부칙과 벌칙규정이 없고 일본의 경관법에는 경관지구조항이 있다는 점 등이 특징이라 할 수 있다. 본 연구에서 도출된 결과들은 앞으로 동아시아지역의 경관계획 또는 경관제도의 확립 및 발전에 기초자료로서 활용할 수 있으리라 기대된다. This study is to compare and analyze the current status of landscape planning system in Korea and Japan by establishing the landscape database utilizing geographic information system(GIS). Specifically, landscape laws and their ordinances enacted in Korea and Japan and their implementation cases were compared to identify the characteristics. As of December 1, 2010, landscape administrative bodies are composed of 472 local governments in Japan while as of March 1, 2010, they are 83 local governments in Korea. The landscape laws in Korea and Japan have a similar structure overall. However, there are no supplementary provision and penal provision in the Korean landscape law whereas there is landscape district provision in the Japanese landscape law. The results of this study would be used as a base for building up the landscape planning and policy in the East Asian region.

본고는 프로젝트에 기초한 개발 연구이다. 여러 해 동안 개발학 분야에서 이용되어 왔던 연구수법이지만, 본론에서는 대학교육에서의 일본어교원 양성 과정의 커리큘럼 연구에 응용했다. 본고의 목적은 본지 제27집(2012)에 필자가 개재한 말레이시아에서 의 교육실습 평가 프로그램에 관한 논문에 대하여, 그 성립 과정의 경위에 대한 문의 가 있어, 이를 밝히고자 함에 있다. 또한, 프로젝트 성립과정에 관한 선행연구를 조사 한 결과, 유럽과 미국에서 개발된 프로젝트에 기초한 개발 연구가 가장 합당한 연구 수단이라는 결론에 이르렀다. 필자는 프로젝트 개발을 커리큘럼 개발에 적용하여 실 시하기 시작한 2009년도부터 작년도까지의 경위를 밝히고 그 변화에 대하여 논리적인 정합성을 취하고 있었는가에 대한 분석을 시도했다. 그에 따라 모든 학문분야에서 가 장 중요한 연구의 재현성을 구현하고, 본 연구를 참조함에 따라 보다 용이하게 벤치 마킹을 할 수 있을 것이다. 본고는 급격하게 저출산이 진행되고 있어 교원의 길이 좁아지는 가운데, 중국, 특 히 영어권에 서 교육실습을 행함으로 경쟁력을 향상시키고, 나아가 다문화화가 진행 되는 한국 사정에도 대응 가능한 차세대형 교원 양성 과정의 파일럿 모델을 제언한다.

The global distribution of calcium on the Moon: Implications for high-Ca pyroxene in the eastern mare region

Yamashita, N.,Gasnault, O.,Forni, O.,d'Uston, C.,Reedy, R.C.,Karouji, Y.,Kobayashi, S.,Hareyama, M.,Nagaoka, H.,Hasebe, N.,Kim, K.J. Elsevier 2012 Earth and planetary science letters Vol.353 No.-

<P><B>Abstract</B></P> <P>The first unambiguous global distribution of Ca on the Moon has been revealed by the Kaguya Gamma-Ray Spectrometer. The observation of the 3737keV gamma rays from <SUP>40</SUP>Ca with a high energy resolution Ge detector, corrected for fast neutrons, improved greatly our confidence in these remote sensing data. While the derived Ca abundance generally confirms the mare-highland dichotomy, we found that the eastern mare regions such as Crisium, Nectaris, and Fecunditatis exhibit unexpected high Ca abundances. This may be explained by regional concentrations of high-Ca clinopyroxene. Our Ca map also shows that the lowest CaO abundance found in the returned samples (∼8wt%) may actually be common in Oceanus Procellarum, suggesting the possible sampling bias of Apollo and Luna missions. These observational results on Ca serve as a complementary criterion for better characterization of mare regions on the Moon.</P> <P><B>Highlights:</B></P> <P>► Global distribution of Ca on the Moon is derived from Kaguya GRS data. ► Observation by high precision Ge detector greatly improved confidence in measurement. ► Ca was found to be more abundant in the east mare region than in the west. ► Selective concentration of high-Ca pyroxene in the eastern mare region is implied. ► Ca provides a complementary criterion to characterize the lunar thermal history.</P>

CHARACTERIZATION OF Ti/Si BINARY OXIDES PREPARED BY THE SOL - GEL METHOD AND THEIR PHOTOCATALYTIC PROPERTIES : THE HYDROGENATION AND HYDROGENOLYSIS OF CH3CCH WITH H₂O

Yamashita, Hiromi,Kawasaki, Shinichi,Ichihashi, Yuichi,Takeuchi, Masato,Harada, Masaru,Anpo, Masakazu,Louis, Catherine,Che, Michel 한국화학공학회 1998 Korean Journal of Chemical Engineering Vol.15 No.5

Titanium-silicon (Ti/Si) binary oxides having different Ti content were prepared by the sol-gel method and utilized as photocatalysts for the hydrogenation and hydrogenolysis of CH₃CCH with H₂O. The photocatalytic reactivity and selectivity of these catalysts were investigated as a function of the Ti content and it was found that the hydrogenolysis reaction (C₂H_6 formation) was predominant in regions of low Ti content, while the hydrogenation reaction (C₃H_6 formation) proceeded in regions of high Ti content. The in situ photoluminescence, diffuse reflectance absorption, FT-IR, XAFS (XANES and EXAFS), and XPS spectroscopic investigations of these Ti/Si binary oxides indicated that the titanium oxide species are highly dispersed in the SiO₂ matrices and exist in a tetrahedral coordination exhibiting a characteristic photoluminescence spectrum. The charge transfer excited state of the tetrahedrally coordinated titanium oxide species plays a significant role in the efficient photoreaction with a high selectivity for the hydrogenolysis of CH₃CCH to producea mainly C₂H_6, and CH₄, while the catalysts involving the aggregated octahedrally coordinated titanium oxide species show a high selectivity for the hydrogenation of CH₃CCH to produce C₃H_6, being similar to reactions of the powdered TiO₂ catalysts. The good parallel relationship between the yield of the photolumunescence and the specific photocatalytic reactivity of the Ti/Si binary oxides as a function of the Ti content clearly indicates that the high phatocatalytic reactivity of the Ti/Si binary oxides having low Ti content is associated with the high reactivity of the charge transfer excited state, of the isolated titanium oxide species in tetrahedral coordination, [Ti^(3+)-O^-]^*.

Analysis, control, and economic impact assessment of major blackout events

Yamashita, Koji,Joo, Sung-Kwan,Li, Juan,Zhang, Pei,Liu, Chen-Ching John Wiley Sons, Ltd. 2008 European transactions on electrical power Vol.18 No.8

<P>Recent large-scale blackouts in North America, Europe, and other countries raised great concerns over the reliability of our electric energy infrastructure and the economic impacts of blackouts. These blackouts were caused by a cascading sequence of events involving line outages, overloading of other lines, malfunctions of protection systems, power oscillations and voltage problems, and system separation and collapse. In this paper, common characteristics of blackouts are identified by analyzing the cascaded events of the blackouts. It is important to take appropriate control actions to alleviate overload and emergency conditions in a power system in order to avoid catastrophic power outages. This paper discusses available control procedures and emergency control systems needed to help prevent catastrophic outages. Economic losses from these blackouts in the U.S., Europe, and other countries were significant. An evaluation of the economic costs of blackouts can be used to estimate the benefits of emergency control systems that can be installed to prevent blackouts. This paper provides an overview of the assessment methods and procedures for evaluation of the economic costs of blackouts. This paper also describes the generic procedure of an event study to measure the economic impact of blackouts on the values of the firms in financial markets.

Knowledge Spillover Effects on Agglomerations of Environment-related Industries

Yamashita, Jun World Technopolis Association 2014 World Technopolis Review Vol.3 No.3

The number of environment-related technologies has increased remarkably over the past two decades, as has the public's interest in effective resource use and ways to reduce the effects of global warming. Industries that are based on environment-related technologies are thus growing rapidly. Previous studies revealed that externalities derived from the population concentration in urban areas positively affect agglomerations of high-tech industries. Such externalities have been named the "knowledge spillover effect". The purposes of the present paper are to (1) give a thumbnail sketch of the locations of environment-related industries around the world, using the Organisation for Economic Co-operation and Development environment-related patent statistics, and (2) explicate the effects of the Marshall-Arrow-Romer (MAR) and Jacobs externalities, which result from population concentrations in urban areas, on the agglomeration of environment-related industries in Sweden. The analysis revealed that environment-related industries are located chiefly in urban areas across the globe, and that only the MAR externalities influenced positively on the agglomeration of these industries in Sweden.

Effect of ammonia treatment on white birch wood

Yamashita, Daichi,Kimura, Satoshi,Wada, Masahisa,Samejima, Masahiro,Takabe, Keiji Walter de Gruyter und Co 2018 Holzforschung Vol.72 No.1

<P><B>Abstract</B></P><P>Transverse sections of white birch (<I>Betula platyphylla</I>) were treated with anhydrous ammonia at 60-140°C (ammonia treatment, AT). As a result, the crystal structure of cellulose in the AT samples changed to cellulose III<SUB>I</SUB>, and acetamide was produced. The surface area of the AT samples, the amount of sugar released upon acid hydrolysis and the lignin content were not changed. However, a small amount of lignin became acid soluble. Mäule color reaction, indicative of the presence of syringyl lignin, showed decreasing color intensities with increasing temperature of AT. The results can be easily interpreted that AT affects ester linkages and side chains of hemicelluloses and syringyl lignin. In addition, AT was carried out on 1-μm thick transverse sections and block specimens. Xylanase treatment and immunolabeling revealed that AT enhances xylan degradation, but ray cells are resistant to xylanase even after AT. On the block sample, a deposited xylan layer appeared on the inner surface of fiber cell walls. Apparently, xylan moved to the surface in contact with the fluid ammonia during AT. The vessel cell wall did not show a similar migration effect, indicating a cell wall-specific interaction with ammonia.</P>

유신체제에서 고등학교 교육과정으로 본 ‘군사적 교육’

Yamashita Kei 전북대학교 인문학연구소 2024 건지인문학 Vol.- No.39

본 연구의 목적은 박정희 대통령 집권 중 유신체제에서 실시한 고등학교 교육과정에서 나타난 ‘군사적 교육’의 의미와 목적을 살펴보는 것이다. 연구방법은 ①'국민교육헌장' 관련 키워드 추출, ②'군사적 교육' 관련 키워드 대조, ③주요 3개 교과의 특징과 분석 결과의 3단계로 나누어서, 학교 교육과정과 군사주의 이데올로기의 연관성에 대해 분석한 것이다. 분석 결과 유신체제기 고등학교 교육과정에서 볼 수 있는 군사적 교육이란 〈협동심〉, 〈국방〉, 〈애국심과 조국에 대한 긍지〉, 〈반공〉, 〈국가와 봉사의 태도〉, 〈규율과 질서〉, 〈효율〉, 〈책임〉을 함양하는 교육이었다. 이는 정부가 근대화를 위한 방법으로 군사적 교육을 이용하여 군사주의 이데올로기를 주입하려 했던 것이다. The purpose of this study is to examine the meaning and purpose of 'military education' in the Senior High School Educational Curriculum conducted by the Yushin system during the Park Chung-hee presidency. This research employed three methods: 1. Extracting keywords from the 'National Chart of Education', 2. Contrasting these keywords with ' Military Education ', and 3. Analyzing the features of three main courses. As a result, the 'Military Education' in the 'High School Curriculum' during the Yushin Regime primarily comprised eight elements: 'Cooperation', 'National Defense', 'Patriotism and Pride in the Homeland', 'Anti-communism', 'Attitude Towards the Nation and Service', 'Discipline and Order', 'Efficiency', and 'Responsibility'. This reflects the government's effort to train citizens who would contribute to modernization through school education, using military education as a mean to instill a militaristic ideology.

Fundamental Characteristics of Onboard Bandwidth-Variable FFT Filter Bank

Yamashita, Fumihiro,Kazama, Hiroshi,Nakasuga, Yoshinori,Ueba, Masazumi 통신위성우주산업연구회 2000 Joint Conference on Satellite Communications Vol.2000 No.-

Voice service is currently the main service in mobile satellite communications, but in the future, there will be a demand for high-data rate services offering multimedia contents. Therefore, an onboard processor capable of handling services of various data rates is required. In the present study, it is assumed that a non-regenerative onboard processor will be used. The onboard processor must have functions to filter signals and convert their frequencies in a channel-by-channel manner. An FFT filter bank satisfies these requirements. However, the conventional onboard FFT filter bank is only applicable to signals of constant bit rate. Hence, the onboard bandwidth-variable filter bank that can handle many signals of various bit rates is proposed. The principle of operation of the bandwidth-variable FFT filter bank is described, then the BER performance of an FPGA-implemented design is evaluated.
