2019년부터 소프트웨어 교육은 모든 초등학생들이 배워야 하는 필수과목이 되었다. 하지만 아직 어떤 식으로 수업을 진행해야 할지에 대해서는 많은 교사들이 낯설어하고 있다. 이에 이 논문에서는 소프트웨어 교육의 핵심이 되는 컴퓨팅 사고력 중 데이터 수집, 분석, 표현 수업에 도움이 되고자 각각의 의미, 세부역량과 성취기준을 제시하고 예시수업을 통해 적용 가능성을 제시하였다. 논문의 전체 과정을 요약하면 다음과 같다. 첫째, 기존의 연구들에서 데이터 관련 역량의 의미, 세부역량 및 성취기준에 관한 연구들을 정리하고 이것을 바탕으로 하여 예비조사를 진행하였다. 예비조사에서는 FGI와 폐쇄형 질문을 동시에 진행하였으며 이를 통하여 전문가들의 검토의견을 반영한 본 조사의 설문 문항을 작성하였다. 둘째, 위의 결과로 만들어진 설문문항을 컴퓨터교육 전공 박사, 박사과정, 소프트웨어교육 담당 교사 및 소프트웨어교육 종사자를 대상으로 하여 타당도, 안정도, 신뢰도를 검증받았다. 셋째, 그 결과 개발된 세부역량과 성취기준 중 '수집방법 선택-문제 상황에 따라 수집 방법을 선택할 수 있다', '데이터의 의미 탐색-분석된 데이터들이 어떤 의미를 갖는지 안다.', '다양한 표현방법 활용-다양한 표현 도구를 사용한다.'를 수업목표로 하여 다섯 차시의 수업을 개발하여 적용하였으며 이 때 교육, 수업, 평가의 일체화를 위해 백워드 2.0 설계모형을 활용하였다. 그 결과 최종적으로 데이터 수집, 분석, 표현의 세부역량과 성취기준을 제시하였다. 이는 초등학교에서 데이터 관련 수업을 계획함에 있어 어떠한 방향으로 수업을 하면 좋을 지에 대한 구체적이고 명확한 기준을 세울 때 도움이 될 수 있을 것이다.

The Satellite Technology Research Centre (SaTReC), Korea Advanced Institute of Science and Technology (KAIST) has developed and is to launch STSAT-1 (Science and Technology Satellite - 1) on 27$^{th}$ September 2003. The data collection system (DCS) is the one of its payloads. The DCS is a data relay system used for transmission from ground-based sensors through satellite to receiving station. This is one of the important methods collecting global data from the remote locations. In this paper, the DCS on the STSAT-1 will be introduced and the development of the mobile terminal (MT) will be reported.

A methodology for collection and analysis of automotive field reliability data is presented. Automotive warranty system usually covers a pre-determined period of time and/or mileage accumulation. Therefore mileage information for the vehicles that have not experienced any failure or problems during the warranty period is not available. In this paper, a reliability analysis method using the estimated mileage distribution from an additional survey for vehicles that have not any record during the warranty period is proposed. Methods of reliability analysis using the warranty information collected under the EU and US warranty policies are also provided.

이 연구에서는 자동 색인을 통해 쉽게 얻을 수 있는 자질의 문헌빈도와 장서빈도를 이용하여 자동분류에서 자질 선정 기법을 kNN 분류기에 적용하였을 때, 어떠한 분류성능을 보이는지 알아보고자 하였다. 실험집단으로 한국일보-20000(HKIB-20000)의 일부를 이용하였다. 실험 결과 첫째, 장서빈도를 이용하여 고빈도 자질을 선정하고 저빈도 자질을 제거한 자질선정 방법이 문헌빈도보다 더 좋은 성능을 가져오는 것으로 나타났다. 둘째, 문헌빈도와 장서빈도 모두 저빈도 자질을 우선으로 선정하는 방법은 좋은 분류성능을 가져오지 못했다. 셋째, 장서빈도와 같은 단순빈도에서 자질 선정 구간을 조정하는 것이 문헌빈도와 장서빈도의 조합보다 더 좋은 성능을 가져오는 것으로 나타났다.

We compared the influences of reconstruction methods using $180^{\circ}$ or $360^{\circ}$ data upon contrasts and discriminating capability and diagnostic accuracy in $^{99m}Tc-MIBI$ stress/rest myocardial SPECT. We reviewed SPECT images reconstructed only with $180^{\circ}$ projection data or with $360^{\circ}$ data in 18 patients and in 11 normal subjects. To compare counts of surface structures and deep structures, we measured ape# posterior wall ratios in 11 normal subjects. To compare the contrasts of images, we measured apex/ventricle ratios. To compare contrasts between normal and diseased myocardial segments, we measured count ratios of defect and normal segments in 4 patients who had single coronary artery diseases. To compare diagnostic accuracy, we scored SPECT images made with $180^{\circ}$ and $360^{\circ}$ data segmentally. Sensitivity and specificity for the diagnosis of coronary artery disease and for the revelation of diseased arteries with both $180^{\circ}$ and $360^{\circ}$ SPECT images. If involved coronary arteries had more narrowing than 50% In coronary angiogram, we considered them as diseased arteries Apex/posterior wall ratios were not different significantly in normal subjects. Apex/ ventricle ratios in normal subjects were different significantly between $180^{\circ}$ and $360^{\circ}$ SPECT images. Defect/normal ratios were different significantly between $180^{\circ}$ and $360^{\circ}$ SPECT images in single vessel disease patients. The overall diagnostic accurracy was the same between $180^{\circ}$ and $360^{\circ}$ data collection. Sensitivity was 94% and specificity was 91% for both types of data collection in this sample population. Sensitivity and specificity of each coronary artery territory were not significantly different between the images made with $180^{\circ}$ and $360^{\circ}$ data. The images made with $180^{\circ}$ data had better contrast between ventricle and myocardium and between hypoperfused and normal myocardium, though no difference was found between the ratios of the myocardial counts of surface and deep structures. However, diagnostic sensitivities of diseased artery territories were not different significantly and so were overall diagnostic accuracy between both methods of making images with $180^{\circ}$ and $360^{\circ}$ data.

When conducting large-scale cohort studies, numerous statistical issues arise from the range of study design, data collection, data analysis and interpretation. In genomic cohort studies, these statistical problems become more complicated, which need to be carefully dealt with. Rapid technical advances in genomic studies produce enormous amount of data to be analyzed and traditional statistical methods are no longer sufficient to handle these data. In this paper, we reviewed several important statistical issues that occur frequently in large-scale genomic cohort studies, including measurement error and its relevant correction methods, cost-efficient design strategy for main cohort and validation studies, inflated Type I error, gene-gene and gene-environment interaction and time-varying hazard ratios. It is very important to employ appropriate statistical methods in order to make the best use of valuable cohort data and produce valid and reliable study results.

Principal component analysis is applied to reduce p-dimensions into q-dimensions ( $q {\leq} p$). Any partition of a collection of data points with p and q variables generated by the application of six hierarchical clustering methods is re-classified by discriminant analysis. From the application of discriminant analysis through each hierarchical clustering method, correct classification ratios are obtained. The results illustrate which method is more reasonable in exploratory data analysis.

Purpose: This study investigated Korean healthcare providers' attitudes toward sexual and gender minority (SGM) persons and their knowledge and behavior concerning the collection of data on sexual orientation and gender identity (SO/GI). Methods: In this cross-sectional, descriptive study, 137 Korean healthcare providers were recruited through convenience sampling from internet communities for medical professionals. A structured questionnaire was created using Google Surveys. The Mann-Whitney U-test, Kruskal-Wallis test, and Spearman correlation analysis were performed. Results: The sample was mostly women (80.3%) and nurses (83.9%), who had overall negative attitudes toward SGM persons and low levels of knowledge and behavior with regard to the collection of patients' SO/GI data. Participants in their 20s, who were religious, and had clinical experiences in treating or providing nursing care for SGM persons had higher levels of knowledge about the collection of SO/GI data. The level of engagement in collecting SO/GI data was higher among women and in their 20s and 30s, unreligious participants, nurses, and those with less than 10 years of clinical experience. Positive attitudes toward SGM persons were associated with higher levels of knowledge, but lower levels of behavior, regarding the collection of SO/GI data. Conclusion: It is important to recognize the diversity of patients' SO/GI and to collect the corresponding information. To this end, it is necessary to develop and use a standardized SO/GI form. Healthcare providers should also receive education and training related to the health of SGM persons to resolve health problems that disproportionately affect SGM persons and related health disparities.
