소프트웨어를 재사용하는 경우 부품의 품질은 새로 개발한 시스템의 품질에 매우 큰 영향을 미친다. 따라서 재사용 라이브러리를 구성할 때 품질에 대한 평가와 검증은 필수적이다. 여러번 다시 사용하는 재사용 소프트웨어는 일반적인 일회적 소프트웨어에 대한 품질 평가와는 다른 기준으로 평가할 필요가 있다. 사용자 인터페이스나 기능적인 측면보다는 확장성과 정확성 등이 더욱 중요한 품질 요소가 된다. 본 논문은 멀티미디어 재사용 부품 저장소 및 재사용 시스템(Reusable Software for Multimedia Objects)의 일부인 객체 부품화 및 품질 평가 기술 개발에 관한 것으로 C++및 IDL(Interface Definition Language)로 표현된 재사용 부품을 읽어 구문 형식, 구조, 객체 결합도, 객체 응집도, 객체 복잡도, 이해도 등의 관점에서 분석하고 품질 만족도를 출력하는 품질평가 도구를 다루었다. 또한 분산 환경에서 품질 검증 시스템을 사용할 수 있도록 CORBA기반에서 설계하였다.

The purpose of the present study was to investigate the characteristics of receptive and expressive language development of cleft palate infants aged under 3. Twenty-six cleft palate infants and 52 normal infants were grouped into 3 chronological age groups with 1 year intervals: less than 1, 1, and 2 years old. The cleft palate infants were divided into 2 groups: cleft palate only, and cleft lip & palate. Each mother of the infants was asked to complete the questionnaire, Sequenced Language Scale for Infants (SELSI). Receptive and Expressive language scores of SELSI were computed. The scores of receptive and expressive language were respectively analyzed into 4 categories of language: phonology/prosody, semantics, syntax, and pragmatics. The results, concerning the differences of language development between the cleft palate and the normal infants, were as follows: (1) expressive language scores were significantly different at age 2 between the cleft palate and the normal infants; (2) cleft plate groups aged less than 1 and 1 showed lower scores of phonology/prosody of expressive language than the normal groups; (3) cleft palate group aged 2 showed lower scores than the normal group in semantics, syntax, and pragmatics. The results, concerning the characteristics of language development between the cleft palate only and the cleft lip & palate infants, were as follows: (1) the scores of expressive and receptive language were not statistically different between the 2 groups; (2) both groups did not show any difference in .the scores of phonology/ prosody, semantics, syntax, and pragmatics of receptive and expressive language.

Objectives: This study aimed to develop a tool for assessing foreigners' understanding of oral health information in Korea called the Test of Korean Functional Health Literacy in Dentistry(TOKFHLiD) and examined validity and reliability of the tool. The TOKFHLiD consists of two literacy assessment parts: Dental Information Sentence(DIS) aims to assess one's literacy of sentences containing oral health information. Dental Information Document(DID) aims to assess one's numeracy and literacy of documents containing oral health information. Methods: Twenty eight preliminary questions were developed based on various medical care literature such as the agreement to diagnosis and treatment and the treatment precautions. DID using 14 preliminary questions was developed based on the appointment card, the treatment schedule, and labels on oral care products. The 42 preliminary questions in the DIS and the DID were subsequently put through four separate expert reviews, in which questions with content validity score of less than 0.8(13/15 points) were corrected and modified by five dental experts and then were corrected for language errors by two Korean language experts. The preliminary assessment tool was tested on 153 Koreans, and ${\chi}^2$ test was performed on the ratio of respondents who comprehended each question, the ratio of respondents who chose the correct answer for each question with a significance level of 0.05. Results: Of the 42 preliminary questions, 1 question in DIS and 1 question in DID, for which the ratio of Korean respondents who chose the correct answers did not exceed the acceptable level of 80%, were excluded and a final assessment tool was completed with 40 questions. Conclusions: Following the development and application of the tool, examination of the TOKHLiD for validity and reliability revealed that this assessment tool is adequate for assessing oral health information literacy of foreigners who are using oral hygiene medical services in Korea.

The present work aimed to present the development of 'Funt', the augmented reality-based digital app as an educational tool for foreign language learning. Our work further evaluated the learning efficacy of the tool by the assessment of the three dependent measures including learning motivation, learning satisfaction, and learning involvement. With a learning app of 'Funt', students can use AR app to access recognition-based or location-based experiences such that any objects, artifacts, or media appear to be in the app. Students are then able to interact with the digital content by manipulating it to learn more about it. Students's engagement should also increase when they create their own experience in AR to demonstrate their understanding of a particular concept or words. Learning effects were evaluated on survey data collected from a hundred respondents aging six to nine years. One-group design for pre-test and post-test was utilized to examine the differences of learning efficacy by comparing the non-'Funt' group and the Funt group scores. A pairwise t-Test was performed for pairwise comparisons between two learning groups. The results indicate that the 'Funt' group scored significantly higher than the non-'Funt' group in the measures of learning motivation, learning satisfaction, and learning involvement. Overall, our results suggest that 'Funt' attracted the students' attention, provided them with a fun context to learn English vocabulary, and develop positive motivation and satisfaction towards vocabulary learning through AR technology.

The purpose of this study is to identify the most important factor(s) that contribute(s) to the overall oral proficiency and to examine whether the factor(s) play(s) a different role depending on the proficiency level of learners. Learners were divided into novice group and advanced group and were asked to produce an oral recording of a story based on a comic strip. The recordings were transcribed and graded by three raters. According to the results, the raters attained high inter-rater reliability when assessing advanced learners. However, the reliability level became considerably lower in the assessment of novice learners. The best predictor of oral proficiency among novice learners was sociolinguistic competence and fluency, while grammatical competence and fluency were the strongest predictors for advanced learners. The results suggest the need for a separate assessment tool for different proficiency levels and the need for a different focus in the classroom depending on the learners' proficiency level.
