Historically, rhythm has played a key role not only in musical composition, but also in architectural design. In 1893, architectural theorist and art scholar August Schmarsow, in "The Essence of Architectural Creation," created a new definition of architecture as space-creation and characterized rhythm as a design principle. However, this new idea was confronted by Heinrich Wölfflin. While Schmarsow's theory represents a dynamic world-view based on anthropomorphism, the architectural theory of Wölfflin is based on the notion of harmony, displaying a kind of conservative stasis. These two main streams have greatly influenced the development of modern architecture. The concept of space has prevailed in the discourse of modern architecture, but the principle of rhythm has seldom received any positive recognition. This article introduces and develops the concept of rhythm and disputes whether Behrens and Frankl in particular, two who dispute Schmarsow's theories, have used the concept of rhythm in terms of space. I conclude that they could not overcome the notion of the physical-the body-, thus their use of the term rhythm is incongruous with the notion of space. The idea of rhythm in architectural creation remains an up and coming idea.

The purpose of this research starts analyzing the case with the United States and Japan and considering the plan form of educational facilities in the advanced country for the improvement of educational facilities in our counties. Japan was managing the educational system which carried out homogeneous till the first stage of the 1970s like advanced nations, such as the educational system of the industrialization age before World War II, i.e., Britain and the United States. The form of an American open school was adopted after the second half of the 1960s, trying the educational system which also globalized the educational system of Japan while the world went into the information society. In the process of the introduction, Japan did not simply imitate a huge open space in the United States. Japan selected the content of the education carefully. And, to do an original educational activity by guidance. The current classroom and multipurpose space were planned as one body. As a result, the environment of the classroom was able to do various studying patterns of individual study and the group study.

The saying likely as "In the rapidly-changing outside management environment, the light-weighted body only able to survive" means the 'lightness' in working space, reducing expenditure for immovable property and unnecessary facility, and also means the flexibility of facility which is ready to cope promptly with the approaching situation. For such reason, as many enterprises do not support an individual workstation for each person but by introduction of sharing system, also reducing the area for working space, they have made the immovable property expense per person curtailed. Though the reduction of the immovable property expense that subsequently gained by merely decreasing of working space brings a remarkable effect of retrenchment, there is also a worrying opinion that because of the narrowed working space than before, or by disappearing of private space, a possible non-productive effect which let working enthusiasm falls down might be brought. By practicing such investigating method, at the first stage survey, the Satisfaction of non-territorial and territorial office user and the order of required improvement are figured out, also arranged the appraisal items as 6 factors in total, and all of the factors were being influenced to the entire satisfaction in statistically meaningful level.

We examined thousands of light curves of stars brighter than 18.0 mag in I band and less than mean magnitude error of 0.1 mag in V band from the OGLE-III eclipsing binary catalogue, and found 90 new binary systems exhibiting apsidal motion. In this study, the samples of apsidal motion stars in the SMC were increased by 250 percent than previously known. In order to determine the period of the apsidal motion for the binaries, we analysed in detail both light curves and eclipse timings using the MACHO and OGLE photometric database obtained for about 20 yrs. For the eclipse timing diagrams of the systems, new times of minimum light were derived from the full light curve combined at intervals of one yr from the survey data. The binaries presented in this paper have apsidal motion periods in the range of 12-918 yrs. An additional short-term oscillation was detected in five systems (OGLE-SMC-ECL-1634, 1947, 3035, 4946, and 5382), which most likely arise from the existence of a third body orbiting each eclipsing binary. All of the selected systems can be used for the statistical study of the interior structure of the stars in the SMC through their apsidal motions due to the homogeneous data and consistent analysis methods.

A virtual reality is a virtual space constructed by a computer that provides users the opportunity to indirectly experience a situation they have not experienced in real life through the realization of information for virtual environments. Various studies have been conducted to realize virtual reality, in which the user interface is a major factor in maximizing the sense of immersion and usability. However, most existing methods have disadvantages, such as costliness or being limited to the physical activity of the user due to the use of special devices attached to the user's body. This paper proposes a new type of interface that enables the user to apply their intentions and actions to the virtual space directly without special devices, and test content is introduced using the new system. Users can interact with the virtual space by throwing an object in the space; to do this, moving object detectors are produced using infrared sensors. In addition, the users can control the virtual space with their own postures. The method can heighten interest and concentration, increasing the sense of reality and immersion and maximizing user's physical experiences.

We utilize times since infall of cluster galaxies obtained from Yonsei Zoom-in Cluster Simulation (YZiCS), the cosmological hydrodynamic N-body simulations, and star formation rates from the SDSS data release 10 to study how quickly late-type galaxies are quenched in the cluster environments. In particular, we confirm that the distributions of both simulated and observed galaxies in phase-space diagrams are comparable and that each location of phase-space can provide the information of times since infall and star formation rates of cluster galaxies. Then, by limiting the location of phase-space of simulated and observed galaxies, we associate their star formation rates at z ~ 0.08 with times since infall using an abundance matching technique that employs the 10 quantiles of each probability distribution. Using a flexible quenching model covering different quenching scenarios, we find the star formation history of satellite galaxies that best reproduces the obtained relationship between time since infall and star formation rate at z ~ 0.08. Based on the derived star formation history, we constrain the quenching timescale (2 - 7 Gyr) with a clear stellar mass trend and confirm that the refined model is consistent with the "delayed-then-rapid" quenching scenario: the constant delayed phase as ~ 2.3 Gyr and the quenching efficiencies (i.e., e-folding timescale) outside and inside clusters as ~ 2 - 4 Gyr (${\propto}M_*^{-1}$) and 0.5 - 1.5 Gyr (${\propto}M_*^{-2}$), Finally, we suggest: (i) ram-pressure is the main driver of quenching of satellite galaxies for the local Universe, (ii) the quenching trend on stellar mass at z > 0.5 indicates other quenching mechanisms as the main driver.

As contemporary art tends to diverge from its fixed genres and intends to appeal to the public, fashion comes to contribute to the contemporary art area, by playing an important part in the creation of artistic value of art work. Nowadays, it is not unusual to see fashion work shown in an art exhibition parallel with art work, since some artists adopt costumes as the medium of their work in order to explore various means of expression. The occurrence of philosophical, sociological theories concerning human body parallelled with the prevalence of the post-structuralist ideas and occurrence of various styles of artistic expressions of body encouraged active research and attracted social attention to body. With such background, fashion art was formed by a means of the integration of body and fashion in order to create extreme artistic expression. 1 intend to investigate a variety of trends in fashion art from the viewpoint of body space. This study developed criteria for fashion image in contemporary art. Those criteria are based on the dichotomy that divides body into inner aspects and outer aspects. According to the criteria, Firstly, the extension type of body shape includes enlargement and reduction as its sub-types. Secondly, the opening-closure type includes opening type and closure type as its sub-types. Thirdly, the intensity type categorizes clothes into uniqueness and hybridity. Dynamism type classifies fashion art into fixation and moving. The various expressions of clothes type are interpreted as a means by which we can criticize many phenomena of modern society, such as loss of humanity, isolation of individuals, loss of identity, commercialism, and materialism. In the latter period of modern society, the integration of the double-faced nature of body and spirit was attempted and popular fashion was introduced into art in order to express desire, death, gender, identity, and sexual pleasure.

최근 들어 정보통신기술과 의료기술의 통합에 관한 관심이 증가되면서 센서네트워크를 인체에 적용하고자 하는 WBAN(Wireless Body Area Networks)에 관한 연구가 활발히 진행되고 있다. 기존의 센서네트워크 기술은 WBAN에 이용될 수 있는 가능성을 가지고 있으나, 몇 가지 제약사항을 가지고 있다. 특히 신체의 각 센서는 신체의 각 부분을 관통하여 통신해야 할 가능성이 크므로 자유공간인 센서네트워크와는 상당히 다른 네트워킹 환경을 가진다. 따라서 WBAN에 관한 연구는 기존의 센서네트워크와는 다른 인체의 특성을 고려한 다양한 영역을 연구의 대상으로 하고 있다. 본 연구에서는 기존의 센서네트워크와는 다른 WBAN의 환경적인 특성을 조사하고, WBAN의 개념이 도입된 2001년 전후부터 SLR(Systematic Literature Review)기법을 이용하여 WBAN의 연구 경향을 체계적으로 조사한다. 이에는 연구 분류와 연구자의 특성 등이 포함된다. 조사 결과를 요약하고 향후 연구 과제를 전망한다.

The purpose of this study was to investigate the bodice prototype method suitable for the upper body shape of old-old aged women using the 3D anthropometric data. And it was to provide the basic data for the upper body garments of old-old aged women. In the overall appearance evaluation, the B pattern was rated as 4.00, and it was evaluated as the most suitable for the bodice prototype of the old-old aged woman. The E pattern was rated lower than normal, and the L pattern and the S pattern were found to be inadequate for older female bodice prototypes. As a result of the measurement of the waist and bust air gap of bodice prototype, the air gap of the bust was not significantly different between the patterns. But the waist air gap showed the largest difference between the L pattern and the S pattern. As a result of evaluating the appearance, the amount of space in the state of 3D simulation, and the air gap, the pattern B appeared to be the most appropriate prototype for the old-old aged women's body shape. However, there is a tendency that the shoulder end point is biased toward the back, so it is necessary to set the inclination of the back shoulder line to be more gentle. Conversely, the front shoulder should be more inclined. In the case of the 3D simulation, the B pattern showed that the other parts generally fit well. In the case of the 3D simulation program used in this study, it was evaluated that it is suitable only for the normal body shape because it is impossible to set the isometric angle which is one of the characteristics of the older female body shape. A study on the bodice prototype suitable for the bent body shape should be carried out through experiments on the actual body shape of various elderly women. In order to cope with the increase of elderly people who are familiar with digital, I think it is necessary to develop an avatar that reflects the old female body shape.

New multiband BVRI light curves of NSVS 1461538 were obtained as a byproduct during the photometric observations of our program star PV Cas for three years from 2011 to 2013. The light curves indicate characteristics of a typical W-subtype W UMa eclipsing system, displaying a flat bottom at primary eclipse and the O'Connell effect, rather than those of an Algol/b Lyrae eclipsing variable classified by the northern sky variability survey (NSVS). A total of 35 times of minimum lights were determined from our observations (20 timings) and the SuperWASP measurements (15 ones). A period study with all the timings shows that the orbital period may vary in a sinusoidal manner with a period of about 5.6 yr and a small semi-amplitude of about 0.008 day. The cyclical period variation can be interpreted as a light-time effect due to a tertiary body with a minimum mass of 0.71 M_⊙. Simultaneous analysis of the multiband light curves using the 2003 version of the Wilson-Devinney binary model shows that NSVS 1461538 is a genuine W-subtype W UMa contact binary with the hotter primary component being less massive and the system shows a low mass ratio of q(m_c/m_h)=3.51, a high orbital inclination of 88.7°, a moderate fill-out factor of 30 %, and a temperature difference of ΔT=412 K. The O'Connell effect can be similarly explained by cool spots on either the hotter primary star or the cool secondary star. A small third-light corresponding to about 5 % and 2 % of the total systemic light in the B and V bandpasses, respectively, supports the third-body hypothesis proposed by the period study. Preliminary absolute dimensions of the system were derived and used to look into its evolutionary status with other W UMa binaries in the mass-radius and mass-luminosity diagrams. A possible evolution scenario of the system was also discussed in the context of the mass vs mass ratio diagram.
