  • Bactrocera depressa and B. scutellata are serious insect pests to pumpkin in Korea. Adult stage which exposes to aerial condition is the optimal target for control because the immature stages of both species hide within host fruit, flowers or under ground. This study aimed to develop an attract-to-kill technique of their females. A commercially available attract-to-kill agent was not effective to attract these two pumpkin fruit flies. This study developed an attractant containing protein-based terpinyl acetate (TA). This TA-protein lure was effective to attract two pumpkin fruit flies. It attracted both sexes with female-biased frequency (60-70%). This TA-protein lure would be used for control both pumpkin fruit flies and may be used for monitoring field populations of B. depressa, in which specific attractant is not known.

  • Recently, there has been much research to improve immersiveness and learning achievement using the edutainment that combines learning with game. However, from the viewpoint of instructors, there has been little research to solve technical difficulties and to reduce the authoring time in tailoring a game-type learning content. Therefore, in this paper, we propose an authoring tool, which enable instructors to tailor game-type learning contents reflecting their own preferences in spite of no backgrounds of technical skills. The authoring tool proposed has key features to hide authoring handicaps and reduce authoring time by providing the overall template for customized game-type learning contents based on template concept. To evaluate the effectiveness of the authoring tool, we applied it to teachers and elementary school students. From the evaluation, the result represented that instructors can make their own learning contents without being aware of technical problems within a short time. Also, the result showed that the learning achievement degree and immersive depth of students have been significantly improved.

  • In recent years, clinicians' and dentists' esthetic demands in dentistry have increased rapidly. The ultimate goal in modern restorative dentistry is to achieve "white" and "pink" esthetics in the esthetically important zones. Therefore, modern esthetic dentistry involves not only the restoration of lost teeth and their associated hard tissues, but increasingly the management and reconstruction of the encasing gingiva with adequate surgical techniques. Interdental space are filled by interdental papilla in the healthy gingiva, preventing plaque deposition and protecting periodontal tissue from infection. This also inhibits impaction of food remnants and whistling through the teeth during speech. These functional aspects are obviously important, but esthetic aspects are important as well. Complete and predictable restoration of lost interdental papillae remains one of the biggest challenges in periodontal reconstructive surgery. One of the most challenging and least predictable problems is the reconstruction of the lost interdental papilla. The interdental papilla, as a structure with minor blood supply, was left more or less untouched by clinicians. Most of the reconstructive techniques to rebuild lost interdental papillae focus on the maxillary anterior region, where esthetic defects appear interproximally as "black triangle". Causes for interdental tissue loss are, for example, commom periodontal diseases, tooth extraction, excessive surgical periodontal treatment, and localized progressive gingiva and periodontal diseases. If an interdental papilla is absent because of a diastema, orthodontic closure is the treatment of choice. "Creeping" papilla formation has been described by closing the interdental space and creating a contact area. In certain cases this formation can also be achieved with appropriate restorative techniques and alteration of the mesial contours of the adjacent teeth. The presence of an interdental papilla depends on the distance between the crest of bone and the interproximal contact point, allowing it to fill interdental spaces with soft tissue by altering the mesial contours of the adjacent teeth and positioning the contact point more apically. The interdental tissue can also be conditioned with the use of provisional crowns prior to the definitive restoration. If all other procedures are contraindicated or fail, prosthetic solutions have to be considered as the last possibility to rebuild lost interdental papillae. Interdental spaces can be filled using pink-colored resin or porcelain, and the use of a removable gingival mask might be the last opportunity to hide severe tissue defects.

  • la this paper, a new digital watermarking algorithm using wavelet transform in frequency domain is suggested. The wavelet coefficients of low frequency subband are utilized to embed the watermark, After the original image is transformed using discrete wavelet transform, their coefficients are transformed into efficient1y in Sequency domain. DCT and FFT transforms are utilized in this processing. Watermark image of general image format is transformed using DCT and the hiding watermark into wavelet coefficients is equally distributed in frequency domain. Next, these wavelet coefficients are performed with inverse transform. The detection process of watermark is performed with reverse direction to insertion process. In this paper, we developed core watermark technologies which are a data hiding technology to hide unique logo mark which symbolizes the copyright and a robust protection technology to protect logo data from external attack like as compression, filtering, resampling, cropping. The experimental results show that two suggested watermarking technologies are invisible and robust.

  • Visual images are very close to our living and we make decisions and choose behavioral options with the visual images on mass media. In current-affair documentary programs, interviews have potential effects that can change public opinions on important issues. Therefore, it's a consequence that the study examined how different expressions of visual images in documentary. Using preceding research methods, this study focus on form, color, movement and depth of visual images. This study analyzed quantitatively all interview shots with 15 current-affair documentary programs from major TV stations such as KBS, MBC and SBS. The findings of the study are 1) half of interview shots used the visual image expressions to hide interviewees' face according to the shield law, 2) choosing close-up shots in company with bust shots, 3) using natural lights and hand-held camera techniques for interviews, and 4) showing wide angles without depths of visual image.

  • This study as one of a series of systematic studies about dancing costumes will compare the costumes of the middle age with their normal style of dress. In brief, this study wants people to know about middle a9e dancing costumes and understand the culture in the middle ages. It was found that people's everyday clothes in the middle age such as Surcot. Surcot-ouvert, Pourpoint, Houppelande were used as dancing costumes. They were, however. changed from the public's clothes which were tight and long. Rather than wearing costume over others. dancers wore costumes which had slits on skirt or sleeves to increase motion. With the Wild Man of the Wood's which only nobles used for their dancing costumes. costumers highlighted the beauty of human body There were various costume materials used in the middle ages like silk. cotton fabrics, linen or brocade. These materials were used for Surcot and Pourpoint as dancing costumes. The naturalness of nature or geometric patterns also was expressed on the costumes. Further about those patterns, because the development of stained glass, vivid colors were used especially red, light green, blue etc. As for the hair styles used, dancers let their hair down and put a jeweled crown over their hair. In summation. dancers wore the same clothes that normal People did, but the costumes were different depending on social status and gender. The costumes of ordinary people's were based upon ordinary clothes that moved and emphasized the dynamic motion. On the other side, the court dancers' costumes were very fancy. symbolizing a measurement of nobles' from wealth and authority. as well as an expression of a sense of beauty, The main features of middle ages follows. : To emphasize vitality, there were long slits on the side of skirt. Hair decorations and jewels are more used than in the ancient age's. To hide a dancer's social status. they could use a mask. Wild Man of the Wood's was used for the body makeup. All these features of the dancing costumes must contribute to the progress of the dance in the middle age's.

  • This paper discusses the programming model of SODA-II that is a baseband processor for software defined radio (SDR) systems. Signal processing On-Demand Architecture Ⅱ (SODA-II) is an on-chip multiprocessor architecture consisting of four processor cores and each core has both an wide SIMD datapath and a scalar datapath. This architecture is appropriate for baseband processing that is a mixture of vector computations and scalar computations. The programming model of the SODA-II is based on C library routines. Because the library routines hide the details of complex SIMD datapath control procedures, end users can easily program the SODA-II without deep understanding on its architecture. In this paper, we discuss the details of library routines and how these routines are exploited in the implementation of baseband signal processing algorithms. As application examples, we show the implementation result of W-CDMA multipath searcher and OFDM demodulator on the SODA-II.

  • Objectives: In most countries around the world, sex work is an illegal activity. Female sex workers (FSWs) in Iran hide their identities, and they are known to be a hard-to-reach population. Despite free access to HIV testing, fewer than half of FSWs receive HIV testing. The purpose of this study was to characterize the reasons for which FSWs do not seek testing at drop-in centers (DICs) and voluntary counseling and testing (VCT) centers in Iran. Methods: A qualitative study was conducted in 2016. The participants were 24 FSWs who received services at VCT centers and DICs for vulnerable females in the north of Iran and 9 males who were the clients of FSWs. In this study, we made use of purposive sampling and carried out a thematic analysis. Results: We found 4 major and 6 minor themes. The major themes were: fear of being infected (with HIV), stigma, indifference, and knowledge. Conclusions: Despite the significant efforts made by the government of Iran to establish and expand DICs for vulnerable females, the number of FSWs receiving services at these centers has not been very considerable. Consequently, by introducing and implementing training programs for peer groups, it may be possible to take steps toward establishing strategic programs for the control and prevention of HIV/AIDS.

  • The purpose of this study is to interpret Landscape of Naeap Village which still preserves the Confucian culture and the traditional clans among the ideally settled villages mentioned in Joong Hwan Lee's "Taengniji" and "Joseon's Fengsui" from the time of Japanese Imperial Rule, from CPTED principles. The following are the findings of this study: First, in terms of access control and zoning, Naeap Village was controlling access from the outside with the natural environment of Banbyeoncheon River and the hills surrounding the village, the artificial environment of human-scale walls around the head house and the dead ends, and the reformation by the Confucian ideologies. Naeap Village, in particular, is prominently configured by the hierarchy of zones; the Gaehosong pine trees, Gyeongpodae, and Naeapssu by the entrance to the village are considered the village itself and the landscapes and valleys are managed by the head house. Second, the Confucian culture across the village, the traditional vegetation method that does not hide the visibility, and the workers in the farms allow natural monitoring. The surrounding visibility is also applied to the spirit of mutual cooperation in the farming society, the culture of commoners at the common well and laundry site, and the culture of ruling class at the towers and pavilions. Third, Traditional villages show the efforts to preserve and maintain the villages with the village rules, the organizational decrees of the clan, and active response to national disasters.

  • In order to guarantee the compatibility of e-Book viewers based on EPUB 3, IDPF launched Readium SDK v1.0 in January, 2015, which was followed by research on the implementation of Readium LCP specifications for user-friendly DRM functions. The complexity of the Readium SDK, however, makes difficulties in interlocking Readium SDK with LCP modules. Moreover, from the perspective of the Readium SDK, which tries to maintain the architecture, independently of any specific DRM technologies, the strong interlock with LCP, as a one DRM, is not desirable. This study represents a Content Protection Framework Model for compatibility of Readium-SDK-based e-Book DRM in order to hide the complexity of Readium SDK and implement an easy interlock between plural DRM and Readium SDK.
