Objective : Our purpose of this study was to determine the clarity and consuming time of fetal surface screening in thirty-eight fetuses from 24 to 32 weeks of gestation by use of two and three-dimensional ultrasonography. Methods : From May 1998 to July 1998, we performed the fetal surface screening of the fetal face, extremities, and spine. Thirty-eight fetuses of 24-32 weeks of gestation (thirty-seven normal fetuses and one abnormal fetus) were studied by use two-dimensional (AI 5200S, 3.5-5.0MHz; Acoustic Imaging Technologic Cooperation, U.S.A.) and three-dimensional ultrasonography (Volusion 530D, 3.5-5.0 MHz ; Kretz-Medicine, Korea). On the fetal face, we evaluated both orbits, nose, lips and brow. Both hands and feet, five digits and toes should be seen in this study. We evaluated cervical spine and lumbosacral junction of the spine. Results : The maternal average age of 38 patients was 29.9 years and the average gestational age was 29.7 weeks. The results of fetal surface screening were as follows : face (both orbits 89.5%, lips 92.1%, nose 92.1%, and brow 89.5%), extremities (both hands 68.4% and feet 73.7%), and spine (cervical spine 94.7% and lumbosacral junction 97.4%) by use of two-dimensional ultrasonography. By use of three-dimensional ultrasonography, results were as follows : face (both orbits 76.3%, lips 81.6%, nose 81.6%, and brow 78.9%), extremities (both hands 76.3% and feet 78.9%), and spine (cervical spine 71.1% and lumbosacral junction 73.7%). Consuming time for two-dimensional ultrasonography were 4.7 minutes for face, 11.6 minutes for extremities, and 5.7 minutes for spine. Using three-dimensional ultrasonography results were 12.8 minutes for face, 17.9 minutes for extremities, and 11.7 minutes for spine. Average consuming time of all fetal anatomic screening was 22.0 and 42.4 minutes by use of two and three dimensional ultrasonography. In one abnormal fetus had cleft lip and polydactyly of right foot which were detected all by three-dimensional ultrasonography, but we couldn't detect the polydactyly by two-dimensional ultrasonography. Conclusion : Three-dimensional ultrasonography was more time-consuming method, but we suggested that three-dimensional ultrasonography was superior than two-dimensional ultrasonography in fetal surface screening.

우종옥,김범기,허명,김찬종,양일호,최관순,김태선 한국교원대학교 과학교육연구소 1999 청람과학교육연구논총 Vol.9 No.1

본 연구에서는 우리 나라 초·중·고등학교 학생들의 과학 탐구 능력에 대한 종단적 추이를 분석하였다. 1997년에는 우종옥 등(1998)이 개발한 검사지를 사용하였으며, 1999년에는 이를 일부만 수정하여 사용하였다. 조사 대상은 성별, 지역별 등을 고려하여 표집하였다. 조사된 자료는 각각 횡단적으로 분석하고, 이를 바탕으로 학생들의 과학 탐구능력이 어떻게 변해 가는지 종단적 추이를 분석하였다. 조사 결과 초등학생들의 과학 탐구 능력은 유의미한차이가 없었으나, 중·고등학생들의 과학 탐구 능력은 유의미하게 향상된 것으로 나타났다. 학교 과학 교육의 질을 과학적으로 관리하기 위해서는 교육과정이 추구하는 교육 목표의 달성이 성공적으로 이루어지고 있는지를 국가수준에서 주기적으로 측정하여 부진의 원인을 진단하고, 개선 방안을 계속 연구하여야 할 것이다. The longitudinal trend of elementary and secondary students' science process skills were investigated to monitor the progress of science learning. Science process skill test, developedin an earlier study on developing a national science process skills assessment system, was revised and administered for the study on March, 1999. Subjects were sampled nation wide according to sex and region. The results of this assessments were compared to those administered on February, 1997. The results showed little difference on science process skills among elementary school students. However, secondary students showed marked increase in science process skills. More systematic and long-term research for assessing science process skills should be planned and performed periodically to provide empirical and foundational data for educational policy making.

Purpose: IS prelminary study was designed to assess the clinical variables influencing on the ward atmosphere in psychiatric closed ward and to promote the quality of psychiatric inpatient treatment. Method: 41 psychiatric inpatients were selected in Chung-ju hospital, Konkuk university. Ward Atmosphere Scale(W AS) was used to evaluate patients' perception of ward milieu. WAS score were compared among subgroups with respect to the clinical variables such as duration of admission, frequency of admission, and diagnosis. Results: Significantly, patients who have hospitalized for 1 month to 2 months reported lower score of WAS and patients who have hospitalized for longer than 2 months reported higher score of WAS. The relationship between educated levels and WAS score was not significant. First admitted patients reported significantly lower score of WAS. Bipolar patients reported significantly higher score of WAS and alcohol related patients reported significantly lower score of WAS. Conclusion: The 1st admitted patients, patients with alcohol problem and educated patients were had less satisfied with psychiatric closed ward. Thus, by considering these factors, more specified therapeutic approach and plan should be conducted.

NBLAST: a graphical user interface-based two-way BLAST software with a dot plot viewer

Choi, Beom-Soon,Choi, Seon Kang,Kim, Nam-Soo,Choi, Ik-Young Korea Genome Organization 2022 Genomics & informatics Vol.20 No.3

BLAST, a basic bioinformatics tool for searching local sequence similarity, has been one of the most widely used bioinformatics programs since its introduction in 1990. Users generally use the web-based NCBI-BLAST program for BLAST analysis. However, users with large sequence data are often faced with a problem of upload size limitation while using the web-based BLAST program. This proves inconvenient as scientists often want to run BLAST on their own data, such as transcriptome or whole genome sequences. To overcome this issue, we developed NBLAST, a graphical user interface-based BLAST program that employs a two-way system, allowing the use of input sequences either as "query" or "target" in the BLAST analysis. NBLAST is also equipped with a dot plot viewer, thus allowing researchers to create custom database for BLAST and run a dot plot similarity analysis within a single program. It is available to access to the NBLAST with http://nbitglobal.com/nblast.

Objective: Sex differences in attachment types are absent during early childhood, but emerge in middle childhood. Prior research has shown that boys classify as more often avoidant than ambivalent. The purpose of this study was to investigate marked sex differences in the distribution of attachment types in middle childhood, especially in boys. Methods: Attachment was assessed with the Separation Anxiety Test in a sample of 208 boys in Grades 3 and 4. Their socioeconomic backgrounds and developmental histories were also collected. Results: The distribution of attachment types was differed from those in early childhood, with insecure boys more often avoidant (31.3%) than ambivalent (7.2%). Insecure-avoidant boys were rated as over 10% compared the global distribution. Conclusion: These results supported the hypothesis of adrenarche in middle childhood. Boys may be changed to have more avoidant types in attachment.
