Reinforcement cells are used to aid grass growth and taken together, this serves to extend greenery beyond the conventional spaces of lawns, tree pits, gardens, and parks, and is advantageous to urban cities since space for greening is often limited. Drought has variable effects on plant life and the resilience of turf to drought resistance also varies with species. Changes in photosynthetic ability were more pronounced for media rather than grass species. The media of sand without organic matter was found to be least suited for drought resistance. Normalized difference vegetation index (NDVI) and digital image analysis (DIA) data were generally in favour of Zoysia species as oppose to A. compressus. In A. compressus, selective traits such as, a more extensive root system and lower specific leaf area (SLA) were not an underlying factor that assisted this grass with enhanced drought resistance. Generally, WUE was found to be strongly related to plant characterises such as overall biomass, photosynthetic features as well as the lushness indexes, and specific leaf area. This study found a strong relationship between WUE and a suite of plant characteristics. These traits should serve as useful selection criteria for species with the ability to resist water stress.

Recent development in multi-channel surround is emerging in various formats to provide better stereoscopic and sound effects to consumers in recent broadcasting. The ability sound localize the sound sources in space is most considerable design factor on multi-channel surround system for human earing perception model. However, this paper propose the change of the sound localization according to the spacing of the speakers, which is not covered in the existing research focus on sound system design. Presently the sound system uses the position and number of the speakers to localize the sound. In the multi-channel surround environment, the proposed design uses the sound localization is caused by the directional characteristics of the speaker, the distance between the speakers and the distance between the listener and the speaker according to the directivity is required. The proposed design is simulated using virtual measurement with MATLAB simulation environment and performances are measured.

The Online business model for purchasing agent service is getting more popular. However, consumers perceive more risk when buying products from foreign online purchasing agents (FOPA) than from common online sellers (COS). This study focuses on finding out how consumers manage risk when they perceive risk and what different risk-reliever strategies they use when buying from high-risk FOPA and low-risk COS. This study has proved the following two. First, when consumers perceive risk at online purchasing, they tend to select risk-reliever strategies, such as the use of communication media, online assurance mark, seller's record, and secure payment to mitigate risk. With the application of those risk-reliever strategies, they built trust with the seller. Second, risk-perception of FOPA influences usage of communication media and check of online assurance mark more strongly than that of COS. On the contrary, risk-perception of COS influences the check of seller record more strongly than that of FOPA. This study helps to explain why FOPA is proliferating, despite its inherent high risk due to the fact that buyers and sellers are separated in time and space and that buyers and sellers have different social and cultural backgrounds. This study also helps managers of E-commerce to relieve consumer's risk-perception and to build trust.

The increasing interest in digital leisure with virtual reality has led to the emergence of digital based urban theme park. Since there were some game type based digital theme parks, which ended up failed in Korea, we analyzed game and space factors for game based digital theme park by drawing upon Maslow's need theory and the hero's journey by Joseph Campbell. We anticipate our research for analysis of game based theme park provides important groundwork on designing various digital urban theme park.

실사 영상에 가상 객체를 합성하기 위해서는 실사 영상 촬영 당시의 카메라 정보가 필요하다. 본 논문에서는 이러한 카메라 정보를 구하기 위하여 가상현실 분야에서 사용하고 있는 캘리브레이션 프리 정합 (Calibration-Free Registration) 기술을 기반으로 한 반자동 정합 기술을 제안하였다. 가상 현실은 실시간 응용인데 반하여 본 논문에서 제안하는 반자동 정합 기술은 합성 컨텐츠 저작을 위한 오프라인 응용에 적합한 방법으로 캘리브레이션 프리 정합기술의 합성 결과는 사용자의 입력정보와 밀접한 관계가 있다. 캘리브레이션 프리 정합기술은 두가지 사용자 입력을 필요로 한다. 첫번째 입력은 어파인공간 (Affine space)의 기저 (Basis vector)를 위한 특징점 정보이고, 두번째 입력 정보는 가상객체의 영상 투영점 입력이다. 본 논문에서는 이 두가지 사용자 입력중 기저를 위한 특징점 정보입력을 사용자가 쉽게, 정확한 정보를 입력할 수 있게하기 위하여, 사용자가 특징점을 개략적으로 입력하게 하고, 주변 영역에서 코너점 검출을 수행하여 사용자 입력을 수정하여 받아들리는 방법을 제안하였다. 실험결과 제안한 방법을 사용하여 구한 카메라 정보로 만족할 만한 합성 영상을 얻을 수 있었다.

Related researches are progressing that method of non-contact method using the electromagnetic field on the human body by detecting the motion recognition signal is the limitations of time and space, so less than the existing systems. In this paper, we designed the circuit system that can implement the hardware that can detect the electric field signal of the human body non-contact method to increase the recognition rate to screen this digital waveform. The PCB design Used to automatically increase of composition of the circuit and the linkage of the comparator digital waveform with circuit simulation of the system. At same time for evaluate the characteristics of the whole circuit system.

This research presents a three-dimensional modeling technique for a flexible sheet. A relative coordinate formulation is used to represent the kinematics of the sheet. The three-dimensional flexible sheet is modeled by multi-rigid bodies interconnected by out-of-plane joints and plate force elements. A parent node is designated as a master body and is connected to the ground by a floating joint to cover the rigid motion of the flexible sheet in space. Since the in-plane deformation of a sheet such as a paper and a film is relatively small, compared to out-of-plane deformation, only the out-of-plane deformation is accounted for in this research. The recursive formulation has been adopted to solve the equations of motion efficiently. An example is presented to show the validity of the proposed method.

The work is devoted to the problem of modernization of the higher education system of Ukraine through the integration of higher education institutions into the European Higher Education Area. Based on the analysis of statistical data, a conclusion was made about the collapse of the higher education system of Ukraine due to a number of problems, which negatively affects the formation of human capital. The importance of international cooperation with the EU in the field of education for the modernization of higher education is substantiated. The institutional principles of formation are investigated, the main priorities of its development at the present stage are determined. The legal bases of European integration of higher education in Ukraine are analyzed. An analysis of the development of international cooperation of Ukrainian universities and their participation in European educational programs. There is a positive tendency to increase the activity of Ukrainian universities in international cooperation, which increases their position in international rankings. Weaknesses of integration processes are revealed and directions of improvement of higher education are offered.

Traditional compound noun decomposition algorithms often face challenges of decomposing compound nouns into separated nouns when unregistered unit noun is included. It is very difficult for those traditional approach to handle such issues because it is impossible to register all existing unit nouns into the dictionary such as proper nouns, coined words, and foreign words in advance. In this paper, in order to solve this problem, compound noun decomposition problem is defined as tag sequence labeling problem and compound noun decomposition method to use syllable unit embedding and deep learning technique is proposed. To recognize unregistered unit nouns without constructing unit noun dictionary, compound nouns are decomposed into unit nouns by using LSTM and linear-chain CRF expressing each syllable that constitutes a compound noun in the continuous vector space.
