과학영재교육원 학생들이 성공적으로 과학 탐구를 수행하기 위해서는 문제 인식, 가설 설정, 탐구 설계, 결론 도출 등의 과학 통합 탐구 능력이 요구된다. 이 연구에서는 김유향(2013)이 개발한 ‘과학 탐구 사고력 측정을 위한 서술형 평가도구’를 사용하여 과학영재교육원 학생들의 과학 통합 탐구 능력을 평가 요소별, 성별, 이수 과정별, 전공 분야별로 비교하였다. 이 평가도구는 탐구 사고력의 주요 요소들인 탐구 문제 도출, 변인 추출, 가설 설정, 실험 설계, 자료 변환, 자료 해석, 결론 도출, 일반화, 평가에 관한 문항이 각 2개씩 총 18문항으로 구성되어 있다. 이 평가도구를 2013년 현재 C 대학교 부설 과학영재교육원에 다니고 있는 학생들 중 102명 학생들(초등과학반 15명, 중등과학심화Ⅰ반 58명, 중등과학심화Ⅱ반 29명)을 대상으로 시행하였다. 그 결과, 과학 통합 탐구 능력의 요소 중 가설 설정, 변인 추출의 점수는 상대적으로 높았고, 자료 변환, 자료 해석, 평가의 점수는 상대적으로 낮았다. ‘자료 변환’에 해당하는 선 그래프 그리기 문항과 ‘평가’에 해당하는 실험 설계의 개선점 찾기 문항의 정답률은 약 40 %로 상대적으로 낮게 나타 났다. 영재교육을 받은 단계별로 비교하면 과학 통합 탐구 능력의 요소들 중 일반화의 경우 유의미한 차이가 있었다. 남학생과 여학생의 점수 차이는 유의미하지 않았다. 이 연구에서 사용한 평가도구가 생물 분야의 소재를 다루고 있어 생물 분야의 영재 학생들과 다른 분야(물리, 화학, 지구과학)의 영재 학생들과 비교한 결과, 유의미한 차이가 없었다. 과학영재교육원 학생들의 과학 통합 탐구 능력 향상을 위하여 자료 변환, 자료 해석, 평가에 관한 교수·학습을 강화하고, 과학 탐구와 관련된 구체적인 교수·학습 자료를 개발할 필요가 있다. The purpose of this study was to investigate science integrated process skill of the students in science education center for the gifted. In order to do this, ``free-response test for the assessment of science process skills`` developed by Yu-Hyang Kim(2013) was administered to 102 students(15 in elementary school science class, 58 in middle school science classⅠ, and 29 in middle school science classⅡ) who attend the program of science education center for the gifted in C university. The assessment tool measured 9 skills ; formulating inquiry questions, recognizing variables, formulating hypotheses, designing experiment, transforming data, interpreting data, drawing conclusions, formulating generalizations, and evaluating the designed experiments. As a result, the students in science education center for the gifted had relatively high scores in the area of ``formulating hypotheses`` and ``recognizing variables``, but they had relatively low scores in the area of ``transforming data``, ``interpreting data``, and ``evaluating the designed experiments``. The 2 items` percentage of correct answers were below 40% ; one is about a drawing a line graph in ``transforming data``, and the other requires finding improvements of the experimental design in ``evaluation``. There was no significant difference between boys`` scores and girls`s one, and between the scores of students in the field of biology and those of students in the other fields(physics, chemistry, and earth science) in science integrated process skills. And there was significant difference according to the periods receiving the gifted education in ``formulating generalizations``. The teaching and learning has to focus on improving science integrated process skills in the program of science education center for the gifted and teaching and learning materials needs to be developed.

이은주,황유경 大田産業大學校 1997 한밭대학교 논문집 Vol.14 No.1

In this paper, the Korean syntactic analyzer is proposed. in which a word formative function is combined to the Pratt's algorithm. In Korean, word consists of head word and the function word, and function word is attached at the end of head word, so it decides the function of word. The fact increase the number of back-trackings and rule applications during parsing. So, the suggested algorithm creases word through Bottom-up parsing and then perform the parsing by the Pratt algorithm. The a1gorithm simplifies parsing procedure. The number of backtracking and rule applications is deduced, and the incorrectness of parsing is easily found. Therefore, the parsing time is decreased.

Objectives : We aimed to evaluate the efficacy of biofeedback-assisted autogenic training for chronic tension-type headache, and to determine the relationship among the changes in electromyography (EMG) activity, headache activity, and mood states according to the psychophysiological treatment. Methods : Chronic tension-type headache patients aged from 20 to 40 years (n=35) were randomized to the treatment group receiving biofeedback-assisted autogenic training (8 sessions) or the monitoring-only control group. EMG activities, headache index, and various psychological variables were examined. Results : We found greater treatment response rate (≥50% reduction in headache index) in patients with biofeedback-assisted autogenic training than in the monitoring group (61% vs. 18% ; χ²=6.882, df=1, p=0.01). There were no significant changes in the mean values of the pretreatment EMG activities across the sessions m either group (all p’s>0.1). Mood states including anxiety and depression improved over time in the both groups, with the improvements being more prominent in the treatment group. Moreover, the reduction in depression level predicted treatment outcome in terms of headache index (95% confidence interval : 0.272-0.966, p=0.039). Conclusion : These results show that biofeedback-assisted autogenic training is effective for the treatment of chronic tension-type headache in a Korean population. Changes in mood states may be closely associated with the clinical outcome in the treatment of chronic tension-type headache using biofeedback-assisted autogenic training.

The purpose of this study was to investigate meal management and nutrition knowledge of the housewives according to their region, age, educational level, income and occupation. The subjects consisted of 2082 housewives residing in big city, middle or small city and agricultural and fishing villages. The portion of housewives living in the middle or small city was 44.1% and the major portion of age distribution was 30's(34.2%). More than half of the housewives(58.5%) had a job. Meal management included in this sutdy was their attitude for meal, nutritional balance in their dishes and harmonizing nutrition knowledge in the life. The meal attitude of the housewives who had no job was the lowest score. Dishes arrangement and harmonizing nutrition knowledge in the life were shown the highest score at the age of 60's. They had experience of nutritional education(63.8% ), The source of nutritional information were in order of TV., radio, relatives & neighbors, newspapers and magazines. The average score of nutrition knowledge was 7.07 out of possible 10 point. Nutrition knowledge had significant correlation with region, age, educational level and income. With increasing educational level, income and decreasing age, the score of nutrition knowledge was getting higher. Also, the housewives of urban was the higher in the nutrition knowledge score than those of rural. The frequency of food intake appeared at the higher in fruits, milk & products than meats & fishes, fishes of eatable bone, yellow green vegetables, and frying and parching food etc.

악성코드에 대한 보다 바람직한 예방은 클라이언트측이 아닌 서버측에서 이루어지는 것이다. 본 논문에서는 새로운 개념 의 서버용 안티바이러스 엔진인 SAVE 1.0을 설계 구현하여 제시한다. SAVE는 기본적으로 1개의 AV모니터와 다수의 AV에이전트로 구성되어 있는데 다중 CPU를 장착한 병렬처리서버의 특징을 직접 활용하기 위하여 관리자가 다중쓰레드 기법을 직접 지정할 수 있도록 하고 있다 악성코드를 5가지 부류로 구분하여 바이러스 시그너쳐 DB를 구축 제공함으로써 부류별 진단을 지정할 수 있도록 하고 있으며 실시간 네트워크 패킷 검사를 통한 악성코드 유입 점검 기능도 제공한다. 웹 기반의 관리자 인터페이스는 뛰어난 사용자 편의성을 제공하고 있다. 성능실험결과 악성코드 검색율은 국내외 상용제품과 비교해서 매우 우수한 것으로 나타났으며 검색속도에 있어서도 서버의 CPU 수 증가에 거의 선형 비례하여 향상되는 특징을 보이고 있다. It is more desirable to prevent and detect the malicious codes in server system rather than in client PCs. In this paper, we suggest a new anti-virus engine, SAVE 1.0, which is executed on a parallel processing server. SAVE consists of 1 AV monitor and several AV agents. A system administrator can control the degree of multi-thread directly in order to enhance the utilization of parallel processing servers. Virus signature DBs in SAVE are classified into 5 categories, which support system administrator's options to use the classifier or not. By real-time checking of network packets, the influx of malicious codes can be prevented. Web-based GUI is one of the convenient functions provided in SAVE. In performance tests, we have confirmed that SAVE has higher virus detection ratio than any other AV engine, and SAVE has a desirable feature as an software of parallel processing servers since the performance of SAVE is improved almost linearly as the CPUs in a parallel processing server increases.

Genetically modified (GM) papaya (Carica papaya L.) line 55-1 (55-1), which is resistant to papaya ringspot virus infection, has been marketed internationally. Many countries such as the European Union, Japan, and Korea have a mandatory safety assessment, approval and labeling regulations for GM foods. Thus, there is a need for specific methods for detecting 55-1. In this study, we established a real-time PCR detection method applicable to 55-1 for a variety of papaya products. The limit of detection was possible for fresh papaya fruit up to dilutions of 0.005% and 0.01% (weight per weight [w/w]) for homozygous SunUp and heterozygous Rainbow cultivars, respectively, in non-GM papaya. The 55-1 event-specific detection method observed parallelism (r2>0.99) between the concentration of line 55-1 cultivars and Ct values obtained in amplification plots at concentrations of 0.005-10% for SunUp DNA and 0.01-10% for Rainbow DNA. The method was applicable to the qualitative detection in various types of processed products (cocktail fruit, dried fruit, juice, etc.) containing papaya as a main ingredient. Monitoring papaya products for the presence of GM papaya were demonstrated using a P35S and T-nos real-time PCR detection method but no amplification signals were detected.

Despite the coronavirus disease 2019 (COVID-19) vaccination roll-out, variant-related outbreaks have occurred repeatedly in Korea. Although public hospitals played a major role in COVID-19 patients’ care, difficulty incorporating evolving COVID-19 treatment guidelines called for a clinical pathway (CP). Eighteen public hospitals volunteered, and a professional review board was created. CPs were formulated containing inclusion/exclusion criteria, application flow charts, and standardized order sets. After CP roll-out, key parameters improved, such as increased patient/staff five-point satisfaction scores (0.41/0.57) and decreased hospital stays (1.78 days)/medical expenses (17.5%). The CPs were updated consistently after roll-out as new therapeutics drugs were introduced and quarantine policies changed.

Eun Joo Yu,이선,강경훈,김백희,Nam Yun Cho,Minhee Choi,Jeong Ho Kim,박석연 대한의학회 2007 Journal of Korean medical science Vol.22 No.2

Several reports have described aberrant methylation in various types of human cancers. However, the interpretation of methylation frequency in various human cancers has some limitations because of the different materials and methods used for methylation analysis. To gain an insight into the role of DNA hypermethylation in human cancers and allow direct comparison of tissue specific methylation, we generated methylation profiles in 328 human cancers, including 24 breast, 48 colon, 61 stomach, 48 liver, 37 larynx, 24 lung, 40 prostate, and 46 uterine cervical cancer samples by analyzing CpG island hypermethylation of 13 genes using methylation- specific PCR. The mean numbers of methylated genes were 6.5, 4.4, 3.6, 3.4, 3.1, 3.1, 3.1, and 2.1 in gastric, liver, prostate, larynx, colon, lung, uterine cervix, and in breast cancer samples, respectively. The number of genes that were methylated at a frequency of more than 40% in each tumor type ranged from nine (stomach) to one (breast). Generally genes frequently methylated in a specific cancer type differed from those methylated in other cancer types. The findings indicate that aberrant CpG island hypermethylation is a frequent finding in human cancers of various tissue types, and each tissue type has its own distinct methylation pattern.

Objective To assess the effect of visuomotor coordination training on the visual perception of geriatric stroke patients. Method Thirty (n=30) cooperative geriatric stroke patients were randomly assigned into 2 groups. The control group received conventional rehabilitation therapy, and intervention group received additional visuomotor coordination training with Dynavision for 30 minutes a day, 3 times a week for 4 weeks. We assessed visual perception and functional status before and after intervention by measuring K-MMSE, K-MBI, K-DRS scores, and by conducting Computerized Neuropsychological Test (CNT) (Maxmedia, Seoul, Korea) 1) visual memory; visual span backward & forward, 2) visual attention; visual continuous performance test (correct response, reaction time), 3) visuomotor coordination; trail making A test. Results The intervention group showed significant improvement in visual attention (p<0.05). There was no significant difference in visual memory, visuomotor coordination and K-DRS (p>0.05). Both groups showed significant increase in K-MMSE and K-MBI scores (p<0.05), but there was no significant difference between the two groups (p>0.05). Conclusion Dynavision training improved the primary visual skill - visual attention, but did not improve higher order visual skills, such as visual memory, visuomotor coordination, cognition or functional performance in the elder stroke patients. Dynavision could be a useful tool for cognitive rehabilitation in patients with cognitive impairment and attention deficit by improving visual attention.
