This paper presents a method of DCT-based illuminant compensation to enhance the accuracy of face recognition under an illuminant change. The basis of the proposed method is that the illuminant is generally located in low-frequency components in the DCT domain. Therefore, the effect of the illuminant can be compensated by controlling the low-frequency components. Moreover, a directional high-order local pattern descriptor is used to detect robust features in the case of face motion. Experiments confirm the performance of the proposed algorithm got up to 95% when tested using a real database.

We propose a method utilizing BLEU(BiLingual Evaluation Understudy), which is widely used in automatic evaluation of machine translations, for an autonomous assessment of a short essay answer. BLEU evaluates translations with an assumption that the translation by a machine is supposed to be more accurate as it is getting to be more similar to the translation by a human. BLEU scores the translation by comparing the n-grams of translations by a machine and humans. Similarly we score students answers by comparing to multiple reference answers with BLEU. In the experiment, we compute correlation coefficient values between scores of our system and human instructors.

This research aims at knowing educational objectives and understanding the whole departmental processes of two-year education programs of junior colleges in the field of ophthalmic optics. Our analyses can be categorized by on liberal art courses, compulsory subjects and optional subjects. The educational purpose of all the seven colleges was training the professional worker, meets well the educational requirements of two year college. All seven colleges' curriculum is open to the national licence examination subjects, but more academic credits are demended in eye examination of refraction, test of ocular function, professional sense of cultural subjects field, leadership in organization and course of marketing related subjects, and stronger relation with clinical examination are also required.

The expression KES, one of the most commonly used words in the Korean language, has various usages. This expression is also used to express English-like cleft constructions. Korean seems to employ at least three different types of cleft constructions: predicational, identificational, and eventual. The paper tries to provide a constraint-based analysis of these three types of Korean cleft constructions and implement the analysis in the LKB(Linguistic Knowledge Building) system to check the feasibility of the analysis. In particular, the paper shows how a typed feature structure grammar, couched upon HPSG, can provide a robust basis for parsing Korean cleft constructions.

A multi-story can be generated by the interactions of users in the interactive storytelling system. In this paper, I suggest narrative structure and corresponding Storytelling Markup Language and implement the system that processes a story presented using this language. This research will be basis of making an authoring tool for interactive storytelling. It can be used to make a story tool and story presentation tool using text, image, animation with user interaction.

본 논문에서는 동영상 내용 기반 검색을 위한 표준 인덱스인 color layout descriptor(CLD)에 기반한 새로운 장면전환검출 방법을 제안한다. 제안한 방법은 입력 영상을 $8{\times}8$ 블록으로 나누고, 그 블록을 대표하는 대표컬러를 선택하여 DCT 변환 후 추출된 DC, AC 계수에 가중치를 부여한 다음 슬라이딩 윈도우를 적용시켜 장면 전환을 검출한다. 이러한 방법은 영상의 전체적인 특성과 국부적인 특성을 동시에 반영하므로, 조명변화나 물체의 움직임에 민감했던 기존 대표적인 방법인 히스토그램 기반 방법과 에지 변화율을 이용한 방법들이 가지는 문제점을 보완할 수 있다. 또한 제안한 방법은 비디오 검색을 위한 MPEG-7 의 검색 서술자 중의 하나인 CLD를 이용하는데 이러한 CLD 는 컬러의 공간적 분포를 잘 설명하므로 MPEG-7 을 위한 검색 서술자에 적합한 장면전환검출 및 검색이 이루어질 수 있다. 제안한 방법을 실험한 결과 기존의 방법보다 장면전환 검출율이 높게 나타났다.

we can set laser patterns with 3D information from vision camera after projected to object with laser stripes. They are very useful for 3-Dimensional informations. We researched the laser patterns of human body projected by stripes and found out three featuring patterns and made database of patterns using Fourier descriptors to recognize the patterns of bodies. The HMM method and Fourier descriptors to recognize human body were experimented. We found out HMM method can recognize human body in more efficient rate than the other.

과거 유비쿼터스 기술의 출현 이후로 사물에 간단한 인식 센서를 이용한 형태의 서비스가 널리 보급되었고, 스마트 기기의 발달로 인해 PC가 아닌 환경에서도 인터넷을 사용하기 용이한 환경이 정착되어, 이들을 이용한 사물 인터넷 (Internet of Things) 환경이 빠르게 확산중이다. 본 논문에서는 상황 인식 서비스와 추론 서비스를 사물 인터넷 환경에 적용 시킨 스마트 홈 상황인식 추론 프레임 워크의 설계 및 구현을 서술한다. 해당 프레임 워크는 실질적인 상황 정보를 제공하는 이기종의 사물 인터넷 기기 간 데이터 타입을 수용하기 위해 온톨로지 언어인 OWL 규격을 사용하여 상황 정보를 수용하고, 룰 입력 모듈을 통해 다양한 환경을 모델링 할 수 있는 XML 규격의 서비스 룰을 입력받는다. 이후, 상황 정보와 서비스 룰을 기반으로 추론엔진을 통해 상황을 추론하여, 단순히 조건 만족 시 실행 구조가 아닌 상황 기반의 추론에 의한 서비스를 제공하게 된다. 프레임 워크를 활용 방안을 설명하기 위해 예제 방범 시나리오를 통해 해당 프레임 워크의 특징 및 서비스의 흐름을 서술한다.

This study was to investigate the types of errors and the frequency of errors to understand students' solving process on the descriptive items with the students of an excellent high school which located in a non-leveling local school district of Gyunggi Province. All 11 items were developed in the equation of a circle and 120 students who attended this high school participated in solving them. The result showed a tendency as follows: Logically invalid inference(Type A, 38.83%) of errors, Omission error of the problem solving process(Type B, 25%), Technical error(Type C, 15.67%), Wrong conclusion(Type D, 11.94%), Use of wrong theorem(Type E, 5.97%), and Use of wrong picture(Type F, 2.61%). The logically invalid inference the students showed with a largest tendency was made because of the lack of reflection. This meant that this error could be corrected in a little treatment of carefulness.
