  • 최근 종이 문서의 전자화가 이루어지면서 기존의 전통적인 펜기반 교정 시스템 또한 온라인 상의 전자 문서 환경에 맞게 구축되고 있다. 이러한 펜기반 입력 기법을 사용하는 교정 시스템에서는 교정 부호와 텍스트 간의 정확한 영역 인식이 중요하며 이를 위해 교정 부호의 특성과 텍스트 영역의 분석이 필요하다. 본 연구에서는 온라인 교정 시스템 모델링을 통하여 온라인 환경에 적합한 교정 부호를 정의하고, 교정 대상 텍스트 영역을 편집 가능한 단위로 구분하여 효율적인 편집 연산이 이루어 질 수 있도록 하였다. 또한 웹 기반의 구조문서(HTML/XML) 편집 환경을 고려하여 편집으로 인한 문서의 구조 정보 변경을 지원하기 위하여 텍스트를 비구조 및 구조정보 텍스트로 분류하여 정의하였다. 본 연구에서는 이러한 모델에 기반하여 교정 부호의 특성에 따른 가변적인 편집 텍스트 영역 인식 규칙 모델을 정의하여 교정부호와 편집 텍스트 영역간의 모호성을 최소화 하고, 편집으로 인한 문서의 구조 정보 변경을 지원하는 시스템을 구현하였다. 결과적으로 온라인 웹 문서 환경에서 펜기반의 모호한 교정 부호의 입력을 인지적인 관점에서 해석하여 보다 정확한 교정 작업 수행을 지원하도록 하였다.

  • We develop single-crystal poly(3,4-ethylenedioxythiopene nanowires using liquid-bridge-mediated nanotransfer printing via vapor phase polymerization. This direct printing method can simultaneously enable the synthesis, alignment and patterning of the nanowires from molecular ink solutions. Twoor three-dimensional complex structures of various single-crystal organic nanowires were directly fabricated over a large area using many types of molecular inks. This method is capable of generating several optoelectronic devices. LB-nTM is based on the direct transfer of various materials from a mold to a substrate via a liquid bridge between them. To demonstrate its usefulness, we used LB-nTM to fabricate nanowire field-effect transistors and arrays of 6,13-bis (triisopropyl- silylethynyl) pentacene (TIPS-PEN) nanowire field-effect transistors.

  • Eight-week-old Spot-billed duck were presented with visible drooping of both of wings. On physical examination, the Spot-billed ducks revealed valgus deformity of the carpal joint resulting in the primary flight feathers protruding dorsally. The bird was in good body condition and there was no loss of motion in any of the joints in the wings. The bird was fed chicken pellet with 18.5% of protein level and reared in a cage. Based on the clinical presentation and physical examination 'angel wing' was diagnosed. Wing bandage and nutritional change to lower-protein diet with fresh vegetables were applied simultaneously. And duck was transferred to wider outside pen with small pond. Four-week afterward clinical signs of angel wing were improved.

  • This study was conducted to evaluate the effects of dietary supplementation of Silybum marianum seed (SMS) extract on the growth performance, nutrient digestibility, fecal noxious gas emission, and hematology parameters in weaned piglets. A total of 120, 21-day-old weaned piglets ([Yorkshire × Landrace] × Duroc) were randomly assigned to 3 groups based on the average initial body weight (6.46 ± 0.45 kg). There were 8 replicate pens per treatment and 5 pigs (mixed sex) per pen. The experimental period was 42 days. Dietary groups included a basal diet, and a basal diet supplemented with 0.05% or 0.10% SMS extract. Feeding weaned piglets with SMS extract containing diet significantly increased average daily gain and average daily feed intake. Additionally, the supplementation of SMS extract had no significant effects on nutrient digestibility, serum hematology, and fecal noxious gas emission parameters. We considered that the supplementation of SMS extract had positive effects on the voluntary feed intake in weaned piglets, thus improving growth performance.

  • Since it is common to have touch-screen devices, it is less challenging to draw sketches anywhere and save them in vector form. Current research on sketches considers coordinate sequence data and adopts sequential models for learning sketch representation in sketch understanding. In the sketch dataset, it has become customary that the dataset is in vector coordinate format. Moreover, the popular dataset does not consider real-life sketches, sketches from pencil, pen, and paper. Art psychology uses real-life sketches to analyze patients. ETRI presents a unique sketch dataset for sketch recognition of autism spectrum disorder in pixel format. We present a method to formulate the dataset for better generalization of sketch data. Through experiments, we show that pixel-based models can produce a good performance.

  • The purpose of this paper is to study the ideal Auto-surveying system and to establish the standard of work procedure involved with completing a precise three-dimensional topographic survey with RTK GPS equipment, a pen based personal computer, and real time CADD software. The fieldwork was done at a golf course which could be regarded as a heavy civil project site such as the reclamation and the site preparation work in December of 1997. The proposed Auto-surveying system and the work procedure in this paper is based on the data processing and the resultant topographic map of the golf course.

  • The purpose of this study is to research and develop solid polymer electrolyte(SPE) for Li polymer battery. The temperature dependence of conductivity impedance spectroscopy and electrochemical properties of PDF/PAN electrolytes as a function of a mixed ratio were reported for PVDF/PAN based polymer electrolyte films which were prepared by thermal gellification method of preweighed PVDF/PAN plasticizer and Li salt. The conductivity of PVDF/PAN electrolytes was 10$\^$-3/S/cm. 20PVDF5PEN LiCiO$\_$4//PC$\_$10//EC$\_$10/ electrolyte has the better conductivity compared to others. 20PVDF5PANLICIO$\_$4//PC$\_$10//EC$\_$10/ electroylte remains stable up to 5V vs. Li/Li$\^$+/. Steady state current method and ac impedance were used for the determination of transference numbers in PVDF/PAN electrolyte film. The transference number of 20PVDF5PANLiCO$\^$4//PC$\_$10//EC$\_$10/ electrolyte is 0.48.

  • Electronic Ink is a stored data in the form of the handwritten text or the script without converting it into ASCII by handwritten recognition on the pen-based computers and Personal Digital Assistants(Pocket PC) for supporting natural and convenient data input. One of the most important issues is to search the electronic ink in order to use it. We proposed and implemented a script matching algorithm for the electronic ink. Proposed matching algorithm separated the input stroke into a set of primitive stroke using the curvature of the stroke curve. After determining the type of separated strokes, it produced a stroke feature vector. And then it calculated the distance between the stroke feature vector of input strokes and one of strokes in the database using the dynamic programming technique.

  • Dye-sensitized solar cells (DSSCs) based on plastic substrates have attracted much attention mainly due to extensive applications such as ubiquitous powers, as well as the practical reasons such as light weight, flexibility and roll-to-roll process. However, conventional high temperature fabrication technology for glass based DSSCs, cannot be applied to flexible devices because polymer substrates cannot withstand the heat more than $150^{\circ}C$. Therefore, low temperature fabrication process, without using a polymer binder or thermal sintering, was required to fabricate necked $TiO_2$. In this presentation, we proposed polymer-inorganic composite photoelectrode, which can be fabricated at low temperature. The concept of composite electrode takes an advantage of utilizing elastic properties of polymers, such as good impact strength. As an elastic material, poly(methyl methacrylate) (PMMA) is selected because of its optical transparency and good adhesive properties. In this work, a polymer-inorganic composite electrode was constructed on FTO/glass substrate under low temperature sintering condition, from the mixture of PMMA and $TiO_2$ colloidal solution. The effect of PMMA composition on the photovoltaic property was investigated. Then, the enhanced mechanical stability of this composite electrode on ITO/PEN substrate was also demonstrated from bending test.

  • The purpose of this study was to investigate the effects of condensed molasses fermentation solubles (CMS) on the growth performance, nutrient digestibility, and backfat thickness of growing pigs. In an eight-week trial, a total of 120 cross-bred ([Landrace × Yorkshire]× Duroc) growing pigs with an average initial body weight (BW) of 25.84 ± 1.60 kg were used. The pigs were randomly assigned to one of two dietary treatments based on body weight and sex. The dietary treatments were as follows: CON - corn-soybean meal-based basal diet (CON) + 2% molasses; and TRT1 - CON + 2% CMS. Each treatment had 12 replicates with five pigs (three gilts and two castrated barrows) per pen. Though there were no significant differences observed in terms of the growth performance and nutrient digestibility (p < 0.05), the backfat thickness in pigs fed 2% CMS tended to increase in week 4 (p < 0.1). Thus, 2% CMS could be optimal to replace molasses given that it does not exert any adverse effects on the performance of growing pigs.
