  • The deer was inseminated at the breeding season, which only shows appearance of the estrus cycles. Early diagnosis of pregnancy is very useful to select non-pregnant does and also very important to decide re-inseminations or mating for producing of calves. Therefore, for the development of techniques on the early diagnosis of pregnancy of deer, the results of this study were summarized as following. (omitted)

  • Difference in the structure of AC PDP cells makes the cells have various discharge characteristics. Therefore, a ramp-reset must be adjusted for the stable driving of AC PDP. If any ramp-reset can reduce the difference in discharge characteristics between cells, the conditions of the address discharge could become almost the same. It is very important to understand these to design a good driving waveform. In this paper, we proved the mentioned facts with the change of barrier rib heights.

  • The relationship study between SMEs' R&D and business performance is important research subject. The objective of this paper is to evaluate whether the effectiveness of government's R&D subsidy for SMEs is supported. The positive perspective is that the support policy stimulates the SMEs innovation activities including R&D and thus contributes to the performance, but the negative view is that the support policy rather decreases the firm's own R&D investment and thus the result is not necessarily promising. This paper is to evaluate the effectiveness of government subsidy on SMEs' R&D. This study suggested DID and Random Effect Models for analysis using the panel data of 2,807 SMEs in manufacturing sector. The data was collected from the 'Survey on SMEs Technology & R&D 2011' conducted by Korea Federation of Small and Medium Business. The results are as follows. First, government's subsidy has crowded out 4.7% of beneficiary's internal R&D investment. Second, government's subsidy has increased 27.3% of beneficiary's R&D intensity in spite of 4.7% internal R&D investment reduction. Third, government's subsidy didn't have a relationship with firm performance but the R&D intensity made positive influence on the firm performance. Finally, R&D intensity has increased the 6.7% of firm performance. These results mean that government's subsidy give a positive impact on SMEs' performance through R&D intensity with relatively small crowding-out effect.

A Comparison on Clothing Appearance of 2D Flat Sketch, 3D Virtual Clothing and Real Clothing -Based on the Evaluation of Chinese in Their 20s and 30s- (의복의 2D 도식화, 3D 가상착의, 실제착의 외관 평가 비교 -20~30대 중국인 평가를 중심으로-)

  • This study investigated similarities and differences between 2D flat sketch, 3D virtual clothing and real clothing images. Flat sketch, 3D virtual clothing, and real clothing images of T-shirts and dresses were made. Questionnaires were prepared for fit evaluation, sensory evaluation, and location evaluation. A survey of 440 questionnaires was collected from Chinese women in their 20s and 30s. As results of the sensibility evaluation, 3D virtual clothing expressed real clothing images slightly more similar than a 2D flat sketch. As results of the fit evaluation of the dresses, 2D flat sketch and 3D virtual clothing were rated as slightly longer/wider, and real clothing images were rated as slightly shorter/narrower. The results suggested that presenting 3D images with avatars as 3D virtual clothing images will provide more accurate fit evaluation results. This study presented possibilities and methods for apparel companies to utilize 3D system as an effective apparel production tool.

  • If you ask many Stereographers how to make a good S3D and you will get all different answers. There are several 3D knowledges and opinions that were not always in agreement. we have to choose which advice to follow and find our own way. But there will be no durable screening of S3D films without a minimal viewing comfort of all the audience whatever the differences of their vision. First of all, We always consider several factors to get an appropriate S3D shot before moving on to production. This is intended to provide a practical example on S3D film production. I hope that this article will encourage further research on this topic.

  • In this paper, we report on the performance stability of solution processible OTFT devices with Au/Ti and ITO source-drain (S/D) electrodes. It appears that the contact resistance of the S/D electrode strongly affects the stability of OTFT devices. Interestingly, the devices with the Au/Ti electrode showed lower mobility than those with the ITO (S/D) devices. The field effect mobilities of the devices with the Au/Ti and ITO electrodes were 0.06, and $0.44cm^2/Vs$, respectively. However, the mobility of the device with the Au/Ti electrode was increased up to $0.26cm^2/Vs$ after 2 weeks, while the mobility of the device with ITO electrode was slightly decreased down to $0.41cm^2/Vs$. The experimental data show us that ITO could be used as the S/D electrode for low-cost OTFT devices.

  • In spite of the advance of 3D solid modeling technology, there are some distinct areas where 2D CAD S/W are still dominant, and more competent comparing with 3D CAD S/W. For example, in the manufacturing of 2D-shaped electrical parts, most related manufacturing tools have 2D geometric features by nature, and 3D solid models applied to these parts have substantial overheads. Nevertheless, most 2D CAD S/W have no topological inquiry services because they have no such information on their geometrical database inherently. Thus, it is needed to extract such information from 2D CAD database for developing more advanced application such as automated drafting/design S/W. In this paper, the extraction of topological information from 2D CAD has been performed in general way using concept of B-rep. A general extraction algorithm, data structure and meta file format for 2D topological object have been developed and successfully applied to the development of the automated lead frame die design system in Samsung Aerospace. it is also possible to provide a flexible, powerful topology-oriented functionality on any common 2D CAD S/W.

  • The investigation of delamination growth behavior in hybrid composite material such as FRMLs should be considered delamination growth rate, dA_D/da$ using the delamination shape factor, $f_S$ instead of traditional fracture mechanics parameters. The main objective of this study is to evaluate the relationship between delamination element (i. e. delamination width, b, delamination contour, c, delamination shape factor, $f_S$ and delamination growth rate, dA_D/da$) and delamination growth in FRMLs under cyclic bending moment. The delamination shape formed along the fatigue crack between aluminum layer and glass fiber/epoxy layer are measured by scanning method. The details of study are as follow : ⅰ) Relationship between crack length, a and delamination width, b. ⅱ) Variation of delamination growth rate, dA_D/da$ was attendant on delamination shape factors, $f_{S1}$, $f_{S2}$, $f_{S3}$. The test result indicated the delamination growth behavior depends in delamination element such as delamination width, b, delamination shape factors, $f_{S1}$, $f_{S2}$, $f_{S3}$.
