한국어 정보처리에서 기본 모듈로 많이 사용되는 형태소분석기, 태거 및 명사추출기에 대한 객관적인 평가를 위해서는 실제 사용되는 언어에 대한 평가기준과 방대한 양의 평가자료 구축이 필수적이다. 전자통신연구원(ETRI)에서는 표준적인 평가기준과 평가자료(말뭉치)를 구축하여 "제 1회 형태소분석기 및 품사 태거 평가대회" 을 개최하였으며, 이 대회는 학습기간을 포함하여 1999년 6월 7일부터 10월 1일까지 진행되었다. 평가에는 총 15개팀이 참가하였고, 명사추출, 태거, 형태소분석기의 각 분야에 대해 약 25만 4천어절의 학습 말뭉치를 제공한 후, 시험말뭉치 약3만 3천어절에 대해 평가가 이루어졌다. 이 글에서는 이 대회의 취지, 진행과정, 평가 방식, 평가결과 등에 대해 소개한다.

In the study, a convergence model of a mobile-based English speaking test was developed. Based on the needs analysis from Korean college students, a speaking test App for iOS and Android mobile devices was developed and its test validity was examined. To develop the test, test items, scoring features and scales were developed. The result of the needs analysis survey showed that 69 out of 87 (79.3%) owned Android phones whereas only 17 (19.5%) held iPhones. Based on the result, an English speaking test App was developed. The technologies used for the test included HTML5, the Javasciript bridge technology, Node and Express, and Mongo DB. In the experiment, five examinees took the test. The test validity was obtained in that all the functions of the test were successfully operated and some feedback was gathered.

This study explores the effects of an video-recording English speaking task model on learners. The learning model, a form of mobile learning, was developed to facilitate the learners' output practice applying advantages of a smartphone and Text-to Speech. The survey results shows the positive effects of the speaking task on the domain of pronunciation, speaking, listening, writing in terms of students' confidence, as well as general English ability. The study further examines the possibilities and limitations of the speaking task in assisting Korean learners improve their speaking ability, who do not have sufficient exposure to English input or output practice due to the situational limitations where English is learned as a foreign language.

This study was carried out to assess the usefulness of thermography for diagnosis and healing process of musculoskeletal disorder in horses. Horses with experimentally induced infectious arthritis were treated with bee venom or antibiotics for 5 weeks from 24 hours after inoculation of Staphylococcus aureus, the effectiveness of the 2 therapeutic drugs treatment was similar to each other. Thermographic evaluation was similar to any other tests, because the thermal pattern tend to return to normal with declining similar to those of clinical signs, laboratory experiments and healing of the lesion. This ability to assess inflammatory change noninvasively make thermography an ideal imaging tool to aid in the diagnosis of certain lameness condition or musculoskeletal disease in horses. These results suggested that thermographic evaluation in horses with musculoskeletal disorders were useful for diagnosis and helpful for monitoring of healing process.

고로슬래그 미분말과 플라이 애쉬와 같은 재료들이 콘크리트의 내구성과 장기강도 증진을 목적으로 혼합재로서 사용되고 있다. 본 연구에서는 고로슬래그 사용 몰탈의 내구성 증진 특성을 활용하기 위하여 고로슬래그 미분말에 알칼리 자극제를 첨가한 알칼리 활성화 슬래그계 무기결합재 사용 몰탈의 내구성과 물리적 특성을 평가하였다. 실험결과, 몰탈의 초기 압축강도 발현에 알칼리 자극제가 큰 영향을 미치는 것을 확인하였다. 또한 알칼리 자극제가 첨가된 몰탈의 화학적 저항성을 평가하기 위하여 공시체를 재령 28 일 후, 5% 황산($H_2SO_4$) 용액에 침지하여 압축강도 및 질량 변화를 관찰하였다. 그 결과, 보통포틀랜드 시멘트로 제조한 몰탈의 경우, 황산용액 침지 후 압축강도가 54% 감소하였다. 반면 고로슬래그 미분말을 첨가한 몰탈의 경우, 약 10% 강도가 감소하였다. 질량변화의 경우, 보통포틀랜드 시멘트로 제조한 공시체는 17%, 고로슬래그 미분말을 첨가한 몰탈은 3%의 질량변화를 보였다. 이 결과로서 고로슬래그 미분말을 첨가한 몰탈의 경우, 화학적 저항성과 물리적 특성이 우수한 것을 확인하였다.

지금까지 사람들의 말하기 습관을 분석하는 것은 전문가나 다른 사람들의 피드백을 통해 이루어졌다. 이는 평가하는 사람에 따라 다른 결과가 나타날 수 있기 때문에 다소 객관성이 떨어지며 직접 대면이 요구되기 때문에 훈련할 수 있는 시간과 공간에 제약이 있었다. 또 지금까지의 말하기 훈련이라 함은 면접 스피치나 발표 스피치 등 특정 목적을 가지고 진행되었기 때문에 말하기에 있어서의 통합적인 훈련을 받기 어려웠다. 본 연구에서는 가장 기초적인 말하기 습관에 초점을 맞추고 말하기 능력을 '어휘력', '계속성', '발음', '속도'라는 4개의 영역으로 나누어 각 영역을 분석하는 알고리즘을 제시한다. 이 알고리즘을 활용한다면 모두 같은 메커니즘을 통해 분석이 이루어지기 때문에 객관성을 보장할 수 있으며 어플리케이션을 활용해 시간과 공간의 제약을 받지 않고 말하기 습관 개선을 위한 훈련을 할 수 있을 것이다.

Horse fat is known to be an effective ingredient in Asia, and the horse fat itself, which is mixed with other ingredients at the additive level, is often sold as a finished product. In this case, physical properties of the horse fat raw material are important. Many horse fats produced in Korea (Jeju) have low temperature stability, so if not stored at low temperatures, segregation may occur. In the case of Japanese horse fat, it is partially hydrogenated or is used the solid phase as the horse fat by separating the liquid phase and the solid phase that is harder and more stable than the horse fat of Jeju. In this study, the physical properties were tested to improve the temperature stability even without the partial hydrogenation process of Jeju horse fat. Various oil gelling agents were used in the study. Results confirmed that the physical properties of the hydroxystearic acid added Jeju horse fat were improved. In addition, stability evaluations at temperatures of 25 ℃, 40 ℃, 45 ℃ and flow behavior evaluations at temperatures of 25 ℃, 30 ℃, 40 ℃ were performed for Jeju horse fat with hydroxystearic acid, 100% Jeju horse fat, and 100% Japanese horse fat. Results showed that the Jeju horse fat improved in flow behavior by adding hydroxystearic acid similar to that of Japanese horse fat. In addition, when the crystal state was observed under a microscope, the thermal stability was improved by decreasing the size of the needle-type crystals with the addition of hydroxystearic acid. Jeju horse fat containing hydroxystearic acid was found to have no physical problems even when stored at room temperature for a long time.

A speech processing model based on a psycholinguistic approach can identify the specific speech processing deficits of children with speech sound disorders (SSDs) through various pathways. In most cases, the cause of the speech problem with SSD children is unknown, so it is important to identify the underlying strengths and weaknesses for individualized intervention. In addition, because the native language deficits can also affect foreign language production, it is necessary to examine speech processing abilities between the two languages. This study is a preliminary study to develop a Korean-English speech processing task system. Speech production task and speech processing task (DT, PRT, NRT) were conducted both in Korean and English on 10 children with SSD and 20 normal children (NSA). As a result, the SSD group showed significantly lower production ability than the NSA group in both languages. As a result of the speech processing task, there was no significant difference in the discrimination task (DT), while there was a significant difference between language types in the phonological representation task (PRT) and between language types and groups in the nonword repetition task (NRT). The results of this study confirmed that children's native language and foreign language processing skills may be different, and that the sub-tasks of speech processing system should be further subdivided.

Speaking skill is an important quality in expressing oneself in school life. Quite a few students experience difficulties at school because of the lack of adequate speaking ability. In order to help them, a Web-based speaking enhancement system is designed and developed using computers equipped with multimedia devices with which students can practice speaking while they are observing graphical representation of voices, which is to cause interest and voluntary participation in the learning activity. The learning system was tested on a group of 44 students of 4th grade in an elementary school. The students were divided into three smaller groups in terms of speaking ability. The experiment shows the effectiveness of the system in building speaking ability.
