The purpose of study correlation between 3D-surface topography and Cobb angle in scoliotic patients. It would be recognizing possibility of clinical application with 3D-surface topography with scoliosis assessment and correlation analysis of obtained Cobb angle through measured results of surface topography and took X-ray of subjects with scoliosis, which used to 3D-surface topography of laser scan method. A scoliosis subjects 16(males 4, females 12) agreed for study's purport volunteer our study that diagnose the scoliosis through 3D-surface topography and X-ray. The results were as follow: It was shown that the relation of Cobb angle of scoliosis and itemized 3D-surface topography measurement in horizontal view(p<0.01). top difference of cervicothoracic and lumbar in anterior-posterior view(p<0.05), the top difference of thoracic, thoracolumbar(p<0.01). These results suggest that an itemized 3D-surface topography measurement was highly correlated with Cobb angle. It would be a useful diagnosis method and assessment of physical therapy plan.

According to living environment, the number of deaths due to thyroid diseases increased. In this paper, we proposed an algorithm for recognizing a thyroid detection using texture analysis based on shape, gray level co-occurrence matrix and gray level run length matrix. First of all, we segmented the region of interest (ROI) using active contour model algorithm. Then, we applied a total of 18 features (5 first order descriptors, 10 Gray level co-occurrence matrix features(GLCM), 2 Gray level run length matrix features and shape feature) to each thyroid region of interest. The extracted features are used as statistical analysis. Our results show that first order statistics (Skewness, Entropy, Energy, Smoothness), GLCM (Correlation, Contrast, Energy, Entropy, Difference variance, Difference Entropy, Homogeneity, Maximum Probability, Sum average, Sum entropy), GLRLM features and shape feature helped to distinguish thyroid benign and malignant. This algorithm will be helpful to diagnose of thyroid nodule on ultrasound images.

Objective: The purpose of this study is to examine the difference between teachers' traumatic experience and teachers' organizational commitment while considering individual differences of the childcare teachers and to investigate the effect of childcare teachers' traumatic experience on organizational commitment. Methods: This study used an online survey and collected data from 235 respondents. Then the data were analyzed by using a one-way ANOVA test, Scheffe post-hoc analysis, and hierarchical regression analysis. Results: First, this study found that there was a statistically significant difference between the traumatic experience of childcare teachers and teachers' organizational commitment depending on the age and career stage of the childcare teachers. Second, the childcare experience of childcare teachers showed a positive correlation with experience, and the traumatic experience showed a negative correlation with the organizational commitment. Third, childcare teachers' traumatic experience had a negative effect on normative and continuous immersion, respectively. Conclusion/Implications: This study contributes to the literature by recognizing the events that occurred in the process of childcare and identified the cause of the decrease in childcare teachers' motivation to work. It also suggests the need for continuous research on traumatic events that childcare teachers' experience during work in order to protect the rights and interests of childcare teachers.

동양 문화권에서는 각종 계약과 서류 결재 등을 위하여 서명대신에 도장이 오랫동안 사용되어 왔으며 아직까지도 보편적인 인증 수단으로 사용되고 있다. 지문과 달리, 도장 영상은 유사한 패턴을 갖지 않고 도장이 찍히는 압력등 입력 상태에 따라서 선명도가 크게 달라진다. 본 연구에서는 입력 장치로부터 얻은 한글 또는 한자 도장 영상을 스트레칭, 이진화 및 잡음처리를 거쳐 판별하는 시스템을 개발하였다. 이 시스템을 가장 보편적으로 사용되는 원형모양의 50개의 도장 영상 (20개 한글 도장, 20개 한자 도장, 10개 유사 도장)에 대하여 실험한 결과, 46개의 도장 영상을 성공적으로 인식하여 비교적 높은 판별도 (92%)를 보였다. 한글과 한자 도장 사이의 차이는 거의 없었으며, 도장을 찍을 때의 각도 차이나 압력 차이가 판별도를 결정하는 중요한 요인으로 작용함을 알 수 있다. 인식할 수 있는 도장 영상의 모양을 원형뿐 아니라 타원과 사각형으로 확장하고 판별도를 좀더 향상하면, 현재 육안으로 확인하는 도장 영상 인식을 자동화하는데 실제로 유용하게 사용될 수 있을 것이다.

The goal of this study was to develop a method to measure the degree of hope of mothers whom their children have cancer. Data collection was held on 144 mothers who had their children diagnosed as cancer, and were treated in C hospital and S hospital located in Seoul. The data was collected from January to August of the year 1999, and collected data was then computerized for T-test, factor analysis and ANOVA. The results are as follows: 1) The measurement method used to measure the degree of hope was divided into 7 categories and composed of 35 questions in total. The level of confidence was 0.90. The 7 categories were named 'gaining insight into life', 'realizing oneself's own role in life', 'attempting a change in life', 'taking in destiny', 'having trust in the treatment being held out by the medical faculty', 'recognizing or escaping from reality' 'obtaining support from religion' respectively. 2) The average score of mothers with cancer children was 3.22. The 6th category 'recognizing or escaping from reality', had the highest score and the 1st category of 'gaining insight into life' the lowest. 3) The degree of hope did not have any differences according to the general characteristics of the children with cancer and the characteristics of the disease. However there was a difference following the characteristics of the mothers with cancer children. Mothers with jobs tend to have scored higher compared with mothers without any occupation.

미래사회 변화에 대비하기 위하여 SW·AI 교육은 필수적이다. 본 논문에서는 예비교사를 대상으로 비대면 SW·AI 교육을 실시한 후 SW 기초교육 효과성 측정도구를 사용하여 교육 전과 후의 SW 교육 효과성을 측정하였다. 분석 결과, 전체 평균과 '컴퓨팅 사고력', 'SW 문해력' 영역의 평균이 유의미하게 증가하였고, '컴퓨팅 사고력' 영역의 분해, 패턴인식, 추상화, 알고리즘 하위영역에서도 모두 교육 전과 후의 평균의 차이가 통계적으로 유의미하게 나타났다. 학생들은 SW·AI 교육을 통해 SW 교육의 필요성과 컴퓨팅 사고력의 중요성을 인식할 뿐만 아니라 정보를 분해하고 패턴을 인식하고 추출하며 문제해결과정을 표현하는 과정을 이해함을 알 수 있었다. 이는 비대면 SW·AI 교육도 SW가 중요함을 인식시키는 것을 넘어 컴퓨팅 사고력, SW 문해력을 향상시키는 효과를 나타내고 있음을 알 수 있다.

There are many prior studies for more natural Human-Computer Interaction. Until now, the efforts is continued in order to recognize motions in various directions. In this paper, we suggest a user-specific recognition by hit detection method using Kinect camera and human proportion. This algorithm extracts the user-specific valid recognition rage after recognizing the user's body initially. And it corrects the difference in horizontal position between the user and Kinect, so that we can estimate a action of user by matching cursor to target using only one frame. Ensure that efficient hand recognition in the game to take advantage of this method of suggestion.

The purpose of this study was to establish different levels of learning satisfaction concerning bakery and confectionery institute students in relation to their educational environment as well as to determine the relationships between variables. A questionnaire was distributed to 260 students enrolled in the bakery and confectionery institute at Gyeongju in the Pohang and Ulsan area, and 242 were used in the final analysis. Collected data were statistically analyzed using SPSS 12.0 Windows. Results of this study can be summarized as follows. The students were mostly satisfied with the learning environment and teaching methods of the institute. A significant difference was observed between male and female students for recognizing teaching methods and major recognition. Furthermore, the educational environment and major recognition of students were positively related with learning satisfaction. Therefore, the staff at the bakery and confectionary institute should provide the proper curriculum and facilities for the students.

Salmonella typhi is frequent causes of foodborne illness and its detection is important for monitoring disease progression. In this study, by using general PCR and novel LAMP (Loop Mediated Isothermal Amplification) assay, we evaluated the usefulness of LAMP assay for detection of Salmonella typhi. In this LAMP assay, forward inner primer (FIP) and back inner primer (BIP) was specially designed for recognizing target invA gene. Target DNA was amplified and visualized as ladder-like pattern of bands on agarose gel within 60 min under isothermal conditions at $65^{\circ}C$. When the sensitivity and reproducibility of LAMP were compared to general PCR, there was no difference of reproducibility but sensitivity of LAMP assay was more efficient than PCR (the detection limit of LAMP assay was 30 fg, while the PCR assay was 3 pg). These results indicate that the LAMP assay is a potential and valuable means for detection of Salmonella typhi, especially for its rapidity, simplicity and low cost.
