To extract the depth map from a single image, a number of CNN-based deep learning methods have been performed in recent research. In this study, the GAN structure of Pix2Pix is maintained. this model allows to converge well, because it has the structure of the generator and the discriminator. But the convolution in this model takes a long time to compute. So we change the convolution form in the generator to a depthwise convolution to improve the speed while preserving the result. Thus, the seven down-sizing convolutional hidden layers in the generator U-Net are changed to depthwise convolution. This type of convolution decreases the number of parameters, and also speeds up computation time. The proposed model shows similar depth map prediction results as in the case of the existing structure, and the computation time in case of a inference is decreased by 64%.

Short stature homeobox-containing gene (SHOX) is a well-known causative gene for the short stature in Turner syndrome. The clinical manifestation of SHOX gene related disorders varies from SHOX haploinsufficiency, presenting with idiopathic short stature, disproportionate short stature, or Leri-Weill dyschondrosteosis (LWD) to recessive form of extreme dwarfism and limb deformity in Langer mesomelic dysplasia. LWD is usually diagnosed upon suspicion based on short stature and skeletal abnormalities, and it is rarely accompanied with respiratory failure in the neonatal period. Here, we report the case of a newborn infant with LWD presenting with severe micrognathia that caused respiratory distress, which was diagnosed using microarray testing. Even when the manifestation of Madelung deformity is not yet apparent, LWD should be considered as one of underlying diseases related to congenital micrognathia.

The normal low-cost manufacturing process for freeform vehicle side mirrors causes deviations from the design curvature. Here, an improved manufacturing process is proposed, combining photorealistic ray-traced visualization of each deviation and subsequent analysis of its deviated reflective scene compared to that of the original design. The proposed mechanism successfully highlights the overlap and mismatch regions of deviated reflected scenes with reference to the desired reflective scenes. We benchmarked the robustness of freeform mirror manufacturing by evaluating the 10, 20, and 30% root-mean-square (RMS) deviated curvature, and concluded that the acceptable deviation needs to be below RMS20% to avoid mismatched regions that could mislead the driver.

雖然韓國和臺灣使用的漢字都屬于繁體字, 但是有些字的字形並不太一樣。筆者對韓國漢字 (韓國敎育用基礎漢字中初中學用900個字) 和臺灣國字標準字體的字形進行了比較, 比較的第一個結果是字形相同的有628個, 佔69.8% ; 字形類似的有241個, 佔26.8% ; 字形不同的有31個, 佔3.4%。比較的第二個結果是韓國和臺灣使用的漢字中有19個"統一碼不同的漢字", 其中字形不同的有"脚腳, 强強, 擧舉, 鷄雞, 敎教, 旣既, 郞郎, 氷冰, 衆眾, 卽即, 窓窗, 靑青, 淸清"等13組 ; 字形類似的有"眞真, 産產, 尙尚, 顔顏, 飮飲"等5組。除此之外, 還有字形完全一模一樣的, 比如"晩"字。這些字應當特别注意一下。從臺灣教育部《國字標準字體教師手冊》第四項 "標準字體的研訂原則與實例"中的5個"硏訂基本原則", 40個"研訂通則"和120個"硏訂分則"可以知道, 臺灣確定的每个字形都是有憑有據的。同時也可以知道臺灣教育部確定字體的一個主要方向是"合乎字理", 它所依據的是《說文解字》的小篆字形的結構, 而韓國漢字的字形一般是沿用《康熙字典》的单字条目上的字形。

Nowadays, as to increased the workability of the press concrete and decrease the cracking, the fiber-reinforced admixture has been widely used. As the low adhesion force between the paste and fiber-reinforced admixture, it was considered as could not be used in the structure. Even more, as the loss of flowability and the exposure of the fiber, further study is needed. In this study, as the different environment and position of the building, the dosages of the fiber-reinforced admixture has also been changed. The fundamental properties and cracking of fiber-reinforced concrete have been tested.

This paper checked the trend of exiting researches on Jeungsan's thought and investigated the academic problems of Daesun's thought as an basic work to form the deep academic discussions on Daesun's thought. Grouping into the scriptures of Jeungsangyo, its theses and papers, I synthesized the present state of researches. In the case of papers, I divided into three periods, before 1990, 1990s' and after 2000. Grouping into three fields, the periods, the researchers and the themes, I investigated the characteristics of the researches of Jeungsan's thought through the main scriptures, theses and papers, and reports of actual state. In conclusion, I brought up the ten problems about academic questions of Daesun's thought.

Purpose: This study is to conduct usability evaluations from the perspective of developing comfort-shoes for the middle-aged and elderly to identify key factors and derive implications for optimal comfort-shoes production. Research design, data, and methodology: A total of 10 middle-aged and elderly women in their 50s and 60s were selected as eligible for the rescue. For data collection, the study was conducted in a Gang Survey, where pre-explanations, shoes test, and interviews were conducted. The collected data were analyzed in a total of four stages. In step 1, the contents obtained through interviews with the subjects were recorded in text, organized and analyzed systematically, and in step 2, unnecessary vocabulary, sentences, and overlapping opinions were eliminated. In step 3, we classified areas around key functions and carried out categorization tasks. Finally, in Step 4, the results and implications of the study were derived by classifying each usability evaluation shoe as positive and negative text around categorized data. Results: There are a total of seven factors for comfort-shoes usability evaluation, which are categorized as cushion, fitting, stability, flexibility, lightweight, comfort, and pressure. Positive/negative factors for the derived usability evaluation factors were shown in the form of a positive-centered, negative-centered, and positive-mixed mix for each of the four products. Positive-focused products are VA products, which are seven times more positive than negative factors. Negative-centered products are CL and SA products, which are five times more negative than positive factors. Positive mixing was a CA product with a ratio of 1:1. Text-based usability evaluations allow us to proceed with analysis based on more scientific data rather than simply listening to opinions and judging by comments. Conclusions: The study discussed implications of developing comfort-shoes for middle-aged consumers and future directions were discussed.

Jeong Geuk-in was a poet of the early Joseon period. He lived for 45 years before Hangeul was published and 35 years afterwards. So, he wrote poetry both in Chinese and Korean. He was a creative writer who wrote Korean poems and songs. There were only a few works written in Korean including and before him. His Korean poems are , and . He created Korean poems and songs by unifying three literary forms of Sijo, Gyeong-gi-che-ga and Gasa. This study was intended to examine written in Korean. For the study, the form of the Bul-woo-heon-ga was analyzed and it was considered as Saseolsijo (a form of sijo with no restrictions on the length of the first two verses) for genre classification. However, it is generally thought that the Saseolsijo appeared in the seventeenth century. Therefore, this study is to explain the reason why Bul-woo-heon-ga is included in Saseolsijo. Another problem is that the writer of Bul-woo-heon-ga is not Jeong Geul-in, because of the fact that the speaker who appears in Bul-woo-heon-ga admired Jeong Geuk-in. In general, people do not admire themselves. As Jeong Geuk-in is a subject to be admired in the book, it is thought that the writer of the book is considered as one of his pupils or friends.

In this study, viscoplastic material properties of solder alloy which is used in the electronics packages are inversely estimated. A specimen is fabricated to this end, and an experiment is conducted to examine deformation by Moir$\acute{e}$ interferometry. As a result of the experiment, bending displacement of the specimen and shear strain of the solder are obtained. A viscoplastic finite element analysis procedure is established, and the material parameters are determined to match closely with the experiments. The uncertainties which include inherent experimental error and insufficient data of experiments are addressed by using the method of computer model calibration. As a result, material parameters are identified in the form of confidence interval, and the displacements and strains using these parameters are predicted in the form the prediction interval.
