한국어 문장 분류는 주어진 문장의 내용에 따라 사전에 정의된 유한한 범주로 할당하는 과업이다. 그런데 분류 대상 문장이 띄어쓰기 오류를 포함하고 있을 경우 이는 분류 모델의 성능을 악화시킬 수 있다. 이에 한국어 텍스트 혹은 음성 발화 기반의 문장을 대상으로 분류 작업을 수행할 경우 띄어쓰기 오류로 인해 발생할 수 있는 분류 모델의 성능 저하 문제를 해결해 보고자 문장 압축 기반 학습 방식을 사용하였다. 학습된 모델의 성능을 한국어 영화 리뷰 데이터셋을 대상으로 실험한 결과 본 논문이 제안하는 문장 압축 기반 학습 방식이 baseline 모델에 비해 띄어쓰기 오류에 강건한 분류 성능을 보이는 것을 확인하였다.

Black chokeberry, Aronia melanocarpa (Michx.) Elliott, is commonly used as a source of jam and jelly in Korea and worldwide. A fungal isolate EML-CCB6 was isolated from the decaying fruit of black chokeberry. Based on the morphological characteristics and rDNA internal transcribed spacer sequence analysis, the isolate was identified as Fusarium tricinctum (Corda) Sacc. This is the first report of post-harvest fruit rot of black chokeberry caused by F. tricinctum in Korea.

An abnormal Korean native cow of five years old with an extra leg was observed macroscopically and radiographically. The results were summarized as follows. 1. External features included two normal forelimbs and hindlimbs, and an extra abnormal forelimb which was underdeveloped. The extra forelimb attached to the regions of back on right scapula. 2. The extra forelimb had antebrachial meromelia. It consisted of undeveloped and severely deformed scapula and humerus, fused carpal bones, imperfectly duplicated metacarpal bones, and polydactyly. The polydactyly was consisted of seven rows of digits with seven hooves, and a rudimentary hoof of dewclaw. 3. The ectopic limp was devoid of muscular tissue.

Two kinds of CNT/TiO2 composite photocatalysts were synthesized with multi-walled carbon nanotubes (MWCNTs) and titanium(IV) n-butoxide (TNB) by a MCPBA oxidation method. Since MWCNTs had charge transfer and semiconducting, the CNT/TiO2 composite shows a good photo-degradation activity. The XRD patterns reveal that only anatase phase can be identified for MCT composite, but the HMCT composite synthesized with HCl treatment was observed the mixed phase of anatase and rutile. The EDX spectra were shown the presence as major elements of Ti with strong peaks. From the SEM results, the sample MCT and HMCT synthesized by the thermal decomposition with TNB show a homogenous sample with only individual MWCNTs covered with TiO2 without any jam-like aggregates between CNTs and TiO2. From the photocatalytic results, we could be suggested that the excellent activity of the CNT/TiO2 composites for organic dye and UV irradiation time could be attributed to combination effects between TiO2 and MWCNTs with plausible photodegradation mechanism.

According to the New Town Development Plan, Gang-buk area, a symbol of slum in Seoul will be changed new residential area. There are a lot of challenges for success this project. First of all, new ways of city plan "pre-plan and development" and "environmentally friendly development" are necessary to carry out this plan. Another important idea is how to overcome conflicts such as unbalanced development, a traffic jam and environment problem. Also, Government and a citizen agree that this project have to accept eco-protectable and sustainable development theory. For increasing green area ratio and keeping eco-diversity, planting at roofs and water circulation system in residential complex are compulsory. Green network based on environmentally friendly development provides a natural energe stream on eco-system and protects a city from air pollution, hot air island phenomenon and a flood.

An experimental investigation with diode laser system was carried out to study the effect of surface heat treatment on the die materials(SM45C, SKD11, SK3). The surface heat treatment characteristics of the laser beam are evaluated using hardness tests, optical microscopy, X-ray diffraction and energy dispersive X-ray spectroscopy(EDS). Results indicated that the beam size, focal length, feed rates are changed surface hardened characteristics. SM45C is higher hardness than other materials and composed to martensite grain at hardened zone, whereas other materials(SKD11, SK3)are low hardness than expected and composed to austenite and allayed martensite at hardened zone. The intensive X-ray diffraction patterns of (110)-(200)-(211) is detected hardened surface and the hardened surface distributed plenty of carbon density than metal zone.

The overlay welding the automobile where the durability is demanded, it is used in the vessel engine valve, plant valve and pump parts. Cause of damage public opinion one what is thought is the fatigue load due to the opening and shutting operation right time repetition of the engine valve. The damage cause of the engine valve or explanation of destruction mechanism is very difficult. The research which it sees to make clear a overlay welding of Co-alloy by Plasma Transferred Arc Weld Surfacing Process reconsideration fatigue crack initiation and fatigue crack growth mechanism at high temperature.

To provide faster service and to relief the road traffic jam, the increase of service speed of conventional railway has been intensively considered. In this study, we measured and analyzed the vibration ride comfort of Saemaeul Train to evaluate the feasibility of 5km/h speed-up in curves and l0km/h speed-up on straight tracks. Four main lines, such as Honam, Kyungboo, ]anghang, Kyungjeon were chosen as representative lines for speed-up feasibility study. The increase of mean ride comfort index in case of speed-up is 0.5-2㏈. The mean ride comfort index of vertical direction in case of speed-up is 107 ∼110 ㏈ for Honam line, 104 ∼112 ㏈ for Kyungboo line, 108∼112 ㏈ for Janghang line and 105∼108 ㏈ for Kyungjeon line. Through this study, we found that the Saemaul Express has slight margin to increase the service speed from the view point of vibration ride comfort.

Recently, wire-EDM became a necessity for many engineering applications, particularly in the dies making. No-Core cut process is helpful for operations in which falling slug can jam the machine or wire. In this paper a proposed CAM system (called NCPP) is introduced, to overcome the limitations of the existing CAM systems in the machining of No-Core cut. The proposed CAM system (NCPP) provides pocketing of No-core cut and optimal selection of the position of starting hole (wire threading point), to minimize toolpath length. It was written for data exchange between CAD-CAM-CNC machines. This data model will become part of the ISO (Data model for Computerized Numerical Controllers) international standard. The NCPP system has been implemented in Visual C++. Many examples are used to illustrate NCPP system. The results show that, NCPP saves the machining time by significant value. This value depends on the shape and complexity of the workpiece that is being cut.
