Degradation of image caused by relative motion between the object and the imaging system (like a camera with its platform) is detrimental to precision photogrammetry. Principal modes of relative motion are identified. The discussion is, however, concentrated on the systematic motions, translatory and rotatory. Various analogical approaches of compensating for the image motion are cited. An analytical-computational approach is presented. This one considers the relationship of transformation bet ween the image and the object, known as the collinearity condition. The standard forms of collinearity condition equations are presented. Augmentation of these equations with regard to both translatory and rotatory motions are expounded. With ever increasing use of high speed computers (as well as analytical plotters in the realm of photogrammetry), this approach seems to be more costeffective and seems to yield better precision in the long run than other approaches that concentrate on analogical corrections to the image itself.

This paper will concentrate on how various particular Southeast Asian conditions created a distinct Southeast Asian cultural identity despite a very challenging geographical and historical diversity in the region. The paper will argue that Southeast Asians demonstrate an ability to adapt to changes and new values but also exhibit fatalism through a very high degree of passive acceptance to political and other changes that affect their society. The paper identifies a degree of environmental and geographical uniqueness in Southeast Asia that shapes context and gives rise to very distinct cultural traits. The historical transformation in the region brought about by colonialism and nationalism, combined with this geographical and political make-up of the region, had an immense impact on Southeast Asian society as it fostered adaptability. Finally, the political transitions brought about by various conflicts and wars that continued to affect the area in rapid succession all throughout the 20^th century likewise contributed immensely to a local Southeast Asian fatalistic response towards change. Historically, Southeast Asia demonstrated these socio-cultural responses to such an extent that these are argued to permeate the region forming a distinct aspect of Southeast Asian culture.

배 농축액의 유가식 배양을 통해 영양원 없이 산도 12% 이상의 고산도 식초를 제조하면서 발효단계(Stage 1-4) 및 초기 알코올농도(6-9%)에 따른 품질특성 변화를 확인하였다. 환원당, 유리아미노산, 총 페놀 함량, 총 플라보노이드 함량 및 라디칼 소거능은 1차 초산발효한 일반산도 식초에 비해 2차 초산발효한 고산도 식초에서 증가하였고, 이는 유가식으로 첨가된 feeding 알코올의 영향으로 사료되었다. SPME/GC-MS 분석을 통한 20여종의 휘발성분은 식초의 산도에 따라 함량의 차이를 나타내었고, 초기 알코올농도의 증가에 따라 자극적인 향의 acid류 함량이 다소 증가하였다. 이상의 결과, 초기알코올 농도 6-7% 조건에서 유가식 배양으로 제조된 고산도 배식초는 일반산도 식초에 비해 우수한 품질을 나타내었고, 이에 관능특성 및 대규모 생산에 대한 연구가 필요한 것으로 사료되었다.

Full Dimension multiple input multiple output (FD-MIMO) architecture employs a planar array design at the Base Station (BS) to provide high order multi-user MIMO (MU-MIMO) via simultaneous data transmission to large number of users. With FD-MIMO, the BS can also adjust the beam direction in both elevation and azimuth direction to concentrate the energy on the user of interests while minimizing the interference leakage to co-scheduled users in the same cell or users in the neighboring cells. In a typical highly populated macrocell environment, modelling the elevation angular characteristics of three-dimensional (3D) channel is critical to understanding the performance limits of the FD-MIMO system. In this paper, we study the throughput performance of FD-MIMO system with varying elevation angular spread and inter-element spacing using a 3D spatial channel model. Our results show that for a typical urban scenario, horizontal beamforming with correlated antenna spacing achieves optimal performance but by restricting the spread of elevation angles of departure, elevation beamforming achieves high array gain with wide inter-element spacing. We also realize significant gains due to spatial array processing via modelling the elevation domain and varying the inter-element spacing for both the transmitter and receiver.

The mathematics education circles in Japan has a variety of subjects. I want to speak w generally are considered on those subjects. Some of these subjects are as follows: (1) The ratio of students who go on to high schools is about 95 percent, so that it is h to solve how to design the mathematics curriculum for the poor scholars. (2) Though the effects of instruction at the schools does not betray the nation's trust, JUKU increase in number. Thus all teachers in schools cannot but endeavor to fulfil the responsibility. (3) Some of the junior high school's teachers suffer from the misconducts and violences pupils. Thus researchers of mathematics education in such schools tend to stagnate. 4) The tudents and pupils get good results in the examinations of calculation, but in the examinations such as word problems that require their judgements not so. Etc. t is not easy to solve or cope with the these subjects. or the subjects as (3), all teachers concentrate their efforts on the activation of lessons the heightening the pupil's will to learn. or the subjects as (4), the idea of mathematical thinking has be advocated since about 1960, recently the 'problem solving' are proposed and are studying. Lastly the researchers in the university are theorizing their own works and digest and utilize arge foreign's literatures. Furthermore a great number of teachers make an effort to research their calssrooms. But a great part of the results of their researches are utilized only in country. I hope, hereafter, that the effects of researches in Japan become known and ized to the foreign countries.

Strategic plan of Subaru science and operation will be introduced. Currently, Subaru has wide variety of instruments, conducts only classical observations, with less than 5 nights allocation for each proposal. Near future, Subaru will emphasize on surveys, introduce queue mode observations, reduce the number of instruments, and concentrate on large size programs. Large surveys are called Subaru Strategic Programs (SSPs). HSC-SSP is on-going (300 nights for 5 years), PFS-SSP will start at around 2020 (360 nights for 5 years), and IRD-SSP from 2016 (TBD). HSC science includes 1) cosmology with gravitational lensing, 2) lensing studies of galaxies and clusters, 3) photometric redshifts, 4) the Solar system, 5) the Milky Way and the Local Group, 6) AGN/quasars, 7) transients, 8) galaxies at low/high redshifts, and 9) clusters of galaxies. PFS science includes 1) cosmology, 2) galaxy & AGN, and 3) galactic archaeology. Subaru is planning the third pillar instrument, so called ULTIMATE-Subaru, which is the GLAO optical-NIR wide field camera & multi-IFU spectrograph for finding galaxies at ultra high redshift (z>10). Finally the strategy from Subaru to TMT will be presented. Subaru will conduct four major SSPs (HSC, PFS, IRD, ULTIMATE-Subaru) in coming decade to provide targets to TMT. HSC performs wide field surveys to reveal the distribution of dark matter in the Universe. IRD surveys Earth-like young planets to discover ~20 Earth-like habitable planets. PFS studies the expanding Universe to provide a few million emission line galaxies to TMT.

This paper describes the PCB drilling using an ultra high-speed air bearing spindle system and micro drill. For this research, we have developed the ultra high-speed air bearing spindle of 125,000 rpm and made an experiment for the application possibility in the PCB drilling. In order to estimate the drilling performance, we have investigated the size and damage of drilled hole, and the wear of drill at 90,000rpm. Results are as follows; we have confirmed the possibility in the PCB drilling of air bearing spindle. In case of micro-drilling PCB at $0.1mm\sim0.3mm$, the increase in the number of drilling has resulted in a bigger size of holes and also a bigger size of damage. It has been found that the wear of micro drill tends to concentrate in the main cutting edge.

A validation study was conducted to determine the efficacy of solvent/Detergent (S/D) inactivation and Q-Sepharose column chromatographic removal of the human immunodeficiency virus (HIV) during the manufacturing of a high purity antihemopilic factor VIII (GreenMono) from human plasma. S/D treatment using the organic solvent, tri (n-butyl) phosphate, and the detergent, Trition X-100, was a robust and effective step in eliminating HIV-1. The HIV-1 titer was reduced from an initial titer of 8.3 log10 TCID50 to undetectable levels within one minute of S/D treatment, HIV-1 was effectively partitioned form factor VIII during Q-Sepharose column chromatography with the log reduction factor of 4.1 . These results strongly assure the safety of GreenMono From HIV.

High-rise apartments of shear wall system are governed by flexural behavior like a cantilever beam. Installation of the damper-brace system in a structure governed by flexural behavior is not suitable. Because of relatively high lateral stiffness of the shear wall, a load is not concentrate on the brace and the brace cannot perform a role as a damping device. In this paper, a friction damper applying flexibility of shear wall is proposed in order to reduce the deformation of a structure. To evaluate performance of the proposed friction damper, nonlinear time history analysis is executed by SeismoStruct analysis program and MVLEM(multi vertical linear element model) be used for simulating flexural behavior of the shear wall. It is found that control performance of the proposed friction damper is superior to one of a coupled wall with rigid beam. In conclusion, this study verified that the optimal control performance of the proposed friction damper is equal to 45 % of the maximum shear force inducing in middle-floor beam with rigid beam.

Recently, new concept and paradigm of 'Environmentally-Friendless' is taking a growing interest in environmental planning and design. This study is to develop the new approach of sustainable development, and to establish the indicators for environmentally-friendliness of "Tourism Farms" in rural areas. A questionnaire survey was conducted for deputy manager group and expert group. The environmentally-friendliness of tourism farms is composed of three categories, conservation of global environment(Low Impact), friendliness to surrounding nature(High Contact), and environmental health and amenities (Health '||'&'||' Amenity). Four indicators, such as saving of energy and water resource, reduction and reuse of garbage, natural purification of sewage disposal, and utilization of natural energy, were affecting the first category, i.e., conservation of global environment(Low Impact). And, friendliness to surrounding nature (High Contact) is affected by 3 indicators, such as contact to nature and diverse green areas, water intimate '||'&'||' contact areas, and natural ecology observation by biotope. Finally, the dimension of environmental health and amenity is affected by 3 indicators, such as nature affinity by farming experience, environmental-friendliness of soil '||'&'||' crops by organic farming, campaign and education programs of environmentally-friendliness. From the result of Importance-Performance Analysis(IPA) for 10 indicators, environmentally-friendliness was recommended as 'Concentrate Here'. And, the content validity of 10 indicators for 3 categories was examined by factor analysis. The result showed as the same as hypothetical model, which proved the validity of hypothetical model.
