  • 이식 전 수정란의 성판정은 많은 축산인의 소망이었다. 많은 방법이 제기되었지만, 세포유전학적 분석방법은 ET의 상용화에 거의 무의미할 정도로 한계가 많았고, 이후 개발된 응성 특이적 항원이나 X-염색체에서 발현되는 효소의 활동을 통한 성판정 방법은 흥미롭기는 하나 산업적 적용에 제약이 많았다. 80년대 중반 Y-염색체 특이적인 DNA 탐침자의 개발과 PCR을 통한 DNA증폭기술의 개발은 수정란 성판정을 획기적으로 개선시켰다. DNA기술을 통한 수정란의 성판정은 분자생물학을 현장으로 진출시킨 첫 경우이기도 했다. 90년대에 세포유전학적 분석에서 FISH가 소개되었으며, 염색체 특이적 library는 다른 기초적이고 응용세포유전학적 연구에 유용한 도구가 되었다. 최근에는 사람에서는 착상전 수정란의 성판별 및 유전진단을 위해 실시되고 있는 형광직접접합법(fluorescent in situ hybridization, FISH)은 효소적 유전자 증폭(polymerase chain reaction; PCR)에 비해 높은 민감도와 정확성을 보이고 있으나 hybridization 및 washing 과정에 매우 긴 시간이 소요되고, 절차도 까다로워 현장에서의 적용이 용이치 않았다. 그러나 direct labelled probe의 이용, heat programmable instrument의 개발, denaturing chemical의 사용배제 등을 통해 소요시간 및 절차의 대폭적인 간소화를 이루어 현장의 적용 가능성을 한층 높이고 있다. 현재 사람의 세포유전학 및 종양학에서는 FISH의 다양한 기술이 많이 이용하고 있으나 소에서는 탐침자(probe)가 개발되어 있지 않아 그 이용이 미미하다. 본 연구는 FISH를 이용하기 위한 탐침자의 개발을 궁극적인 목표로 삼았으며, 이를 위해 접근이 용이한 방식을 개발하여 기존의 방식과는 다른 소 배아세포의 성을 판별 할 수 있는 접근방법을 소개 하고자한다.

  • This paper presents an analysis of feature extraction methods used for distinguishing the speech of patients with cleft palates and people with normal palates. This research is a basic study on the development of a software system for automatic recognition and restoration of speech disorders, in pursuit of improving the welfare of speech disabled persons. Monosyllable voice data for experiments were collected for three groups: normal speech, cleft palate speech, and simulated clef palate speech. The data consists of 14 basic Korean consonants, 5 complex consonants, and 7 vowels. Feature extractions are performed using three well-known methods: LPC, MFCC, and PLP. The pattern recognition process is executed using the acoustic model GMM. From our experiments, we concluded that the MFCC method is generally the most effective way to identify speech distortions. These results may contribute to the automatic detection and correction of the distorted speech of cleft palate patients, along with the development of an identification tool for levels of speech distortion.

  • The purpose of this study was to develop and validate of the K-SRBCSS (Korean Version of Scales for Rating the Behavioral Characteristics of Superior Students), considering educational-social context and linguistic differences. The developed K-SRBCSS includes 58 items, which are consisted of 55 items from translation of original SRBCSS into Korean and three newly developed items that reflect Korean situation. Teachers and parents rated students' behavioral characteristics about 58 items in 6 scales. The results of this study were as follows. K-SRBCSS is valid and reliable scale. The differences of the rating of characteristics between gifted students and general students if significant. Gifted students got higher scores on every scales than general students. It means K-SRBCSS is useful to discriminate the gifted. The differences of the rating between parents and teachers showed insignificant results, which mean that teachers and parents rate students's characteristics similarly. K-SRBCSS will be a very useful scale that could find some hidden talents if this scales would use complementarily with other sophistication methods in identifying the gifted.

  • The OSTG (Observation Scale for Teachers of the Gifted in Korean Traditional and Western Music) is one of the tools for screening of the Gifted in Korean traditional and Western music. So the validity and reliability of the OSTG-2 has an influence on securing validity of the whole identification process. The purpose of this study is to examine the validity and reliability of the OSTG-2 that input screening processing, and to suggest systematization of identification processing for the Gifted in Korean traditional and Western Music. For the achievement of this purpose, this study administered the OSTG-2 to 195 teachers of gifted students aged between 13 and 16 in the middle or high school for the arts. To validate the OSTG-2, I analyzed items of the OSTG-2, and conducted the exploratory and confirmative factor analysis. I also examined the internal consistency. As a result of the exploratory factor analysis, I collected 22 items of the OSTG-2 finally. Furthermore, I could identify psychological construct of the Gifted in Korean traditional and Western Music. The consequence of confirmative factor analysis, the model provided good fit to observed data. As a result of reliability analysis, the internal consistency of musicality verified cronbach' ${\alpha}$=.852, and the creativity verified cronbach' ${\alpha}$=.894, the task commitment verified cronbach' ${\alpha}$=.924. This result of validity study reflects the fact that the OSTG-2 is a valid scale and is able to input to gifted educational field instantly.

  • In this paper, we propose a method to recognize the braille blocks for embedded devices in real time through deep learning. First, a deep learning model for braille block recognition is trained on a high-performance computer, and the learning model is applied to a lightweight tool to apply to an embedded device. To recognize the walking information of the braille block, an algorithm is used to determine the path using the distance from the braille block in the image. After detecting braille blocks, bollards, and crosswalks through the YOLOv8 model in the video captured by the embedded device, the walking information is recognized through the braille block path discrimination algorithm. We apply the model lightweight tool to YOLOv8 to detect braille blocks in real time. The precision of YOLOv8 model weights is lowered from the existing 32 bits to 8 bits, and the model is optimized by applying the TensorRT optimization engine. As the result of comparing the lightweight model through the proposed method with the existing model, the path recognition accuracy is 99.05%, which is almost the same as the existing model, but the recognition speed is reduced by 59% compared to the existing model, processing about 15 frames per second.

  • The purpose of this study is to develop and validate the Korean Job Crafting Scale. First, previous studies on the concept and measurement of job crafting were reviewed, and items were developed based on this review. The content validity of the scale was examined using a focus group interview consisting of 10 HRM professionals. Following modification of the items, the measurements were administered to 305 employees from 8 Korean firms, and exploratory factor analysis was conducted in order to examine the factorial validity of the scale. Subsequently, confirmatory factor analysis was implemented concerning data collected from 295 employees who work in 7 Korean firms. Results indicated that the measurement model sufficiently explained the data at an appropriate level, and the subscales featured convergent and discriminant validity. If the scale developed in this study is validated in further studies, it can be employed to conduct research regarding job crafting in Korean organizations.
