스트림 데이터는 끊임없이 고속으로 생성되는 데이터로써 최근 이러한 데이터를 분석하여 부가가치를 얻고자 하는 노력이 활발히 진행 중 이다. 본 연구에서는 스트림 데이터의 다차원적 분석을 위해 큐브를 고속으로 계산하는 방법을 제안한다. 스트림 데이터는 비즈니스 데이터와는 달리 정렬되지 않은 채로 도착하며, 데이터의 끝에 도달하지 않은 상태에서는 집계 결과를 낼 수 없어서, 고속으로 집계하는 과정에서 저장 공간의 낭비를 심하게 초래한다. 또한 큐브에 속한 집계 테이블들을 모두 생성하는 것은 시간/공간 측면에서 비효율적이라는 점이 지적되고 있다. 이러한 문제를 해결하기 위해 본 연구에서는 기존 연구들과 마찬가지로 큐브에 포함시킬 집계 테이블들을 사용자가 미리 정하도록 하였고, 정렬되지 않은 스트림 데이터를 고속으로 집계하는 과정에서 배열과 AVL 트리들로 구성된 자료구조를 집계 테이블의 임시 저장소로 사용하였다. 제안한 알고리즘은 생성하려는 큐브가 메모리에 상주할 수 없을 정도로 큰 경우에도 집계 연산을 수행할 수 있다. 이론적 분석과 성능 평가를 통해 제안한 큐브 계산 알고리즘이 실용적임을 입증하였다.

설문조사를 실시할 때 응답자가 설문조사의 일부 문항에 대하여 응답하지 않는 경우 항목무응답이 발생한다. 무응답이 발생한 자료를 제외하고 완전하게 응답된 자료 만에 근거한 분석은 분석 결과에 편의가 발생할 수 있으므로, 이를 채워 넣어 완전한 형태의 자료로 분석하기 위해서 무응답 대체가 흔히 사용되고 있으며 여러 가지 무응답 대체 기법들을 비교하는 연구들도 많이 존재한다. 패널조사 연구는 연구 대상 패널에 대하여 정해진 시간에 따라 반복적으로 동일한 설문 문항에 대하여 응답을 조사하여 시간에 따른 변화를 살펴보는 조사 방법을 나타낸다. 패널조사 자료의 항목 무응답을 대체할 때 이전 시점의 응답 자료가 존재한다면 이를 포함하여 대체를 실시하는 것이 바람직한 것으로 여겨져 왔으나 이에 관한 직접적인 연구는 찾기 힘들다. 따라서 본 연구에서는 패널자료에서 이전 시점의 정보를 고려하지 않고 대체를 실시하는 방법과 이전 시점의 정보를 활용하여 대체하는 방법들 중에서 어느 대체 방법이 보다 적절한 대체를 제공하는지 살펴보았다. 특히 이전 시점의 응답 정보를 이용하는 방법인 비대체, 선형혼합모형을 이용한 대체와 선형혼합모형에 근거한 베이지안 대체 방법을 고려하였고, 이를 이전 시점의 정보를 고려하지 않는 대체 방법들 중 흔히 사용되는 평균대체, 핫덱대체 방법과 비교하였다. 모의실험 결과 선형혼합모형에 근거한 베이지 안 대체 방법이 다른 대체 방법에 비해 무응답 비율이 높아지더라도 편의도 작으며 평균에 관한 95% 신뢰구간의 포함률도 높게 나타나서 가장 좋은 대체 방법으로 확인되었다.

Objectives: Since 1998, the Korea National Health and Nutrition Examination Survey (KNHANES) has been conducted in order to investigate the health and nutritional status of Koreans. The food intake data of individuals in the KNHANES has also been utilized as source dataset for risk assessment of chemicals via food. To improve the reliability of intake estimation and prevent missing data for less-responded foods, the structure of integrated long-standing datasets is significant. However, it is difficult to merge multi-year survey datasets due to ineffective cleaning processes for handling extensive numbers of codes for each food item along with changes in dietary habits over time. Therefore, this study aims at 1) cleaning the process of abnormal data 2) generation of integrated long-standing raw data, and 3) contributing to the production of consistent dietary exposure factors. Methods: Codebooks, the guideline book, and raw intake data from KNHANES V and VI were used for analysis. The violation of the primary key constraint and the $1^{st}-3rd$ normal form in relational database theory were tested for the codebook and the structure of the raw data, respectively. Afterwards, the cleaning process was executed for the raw data by using these integrated codes. Results: Duplication of key records and abnormality in table structures were observed. However, after adjusting according to the suggested method above, the codes were corrected and integrated codes were newly created. Finally, we were able to clean the raw data provided by respondents to the KNHANES survey. Conclusion: The results of this study will contribute to the integration of the multi-year datasets and help improve the data production system by clarifying, testing, and verifying the primary key, integrity of the code, and primitive data structure according to the database normalization theory in the national health data.

This study contributes to the development of a creative fashion design and provides concrete data regarding the process of creative ideas through an analysis of the characteristics of the fashion design idea and the characteristics of fashion design from a formative perspective according to Osborn's checklist method. The data collection involved 466 pages that focused on the work of 30 designers (2005 S/S-2009 F/W) extracted from the websites style.com and ifb.co.kr. In the cases of pictures collected, a content analysis was applied based on statistical analysis and design analysis criteria. First, as a result of the examination of the characteristics of ideas for fashion design based on the checklist, it turned out that elimination method is most frequently employed, followed by addition, conversion, limit and combination. In addition, every idea showed a significant difference in terms of the applied item, expression method, and balance. Second, due to the study of the formative characteristics of fashion design (based on the checklist), it turned out that square-shaped silhouette, achromatic and chromatic colors, combined tones, identical color combination, complex texture, and identical texture combination are frequently used. In addition, every idea showed a significant difference in terms of form, color, and fabric. We believe that the use of the checklist is useful for the development of a creative design because formative characteristics vary based on the characteristic of ideas of fashion design.

The authors investigated the effect of feedback and remediation after formative assessment (FRFA) by comparing the FRFA score and that of summative assessment (SA) in a course on clinical skills. In March 2015, 33 subjects underwent evaluation of their ability to perform a complex clinical skill using a real-time ready-made mobile assessment form tool, and through e-mail they were supplied with their feedback and final score (the pass group earned 2 points; the intermediate group earned 1 point; the nonpass group earned 0 points) followed by their self-reflection. The nonpass group underwent a re-test and e-mail feedback again until they passed the test, given the ease of performance. In December 2015, the 33 subjects took a 10-item SA, and one of the 10 items addressed a similar clinical skill. The difference between the first score on the FRFA and the score on the SA was evaluated statistically (p=0.05) through data analysis, variance distribution, correlation analysis, and linear regression analysis using SPSS software ver. 16. The increase from the score on the SA to that on the FRFA was statistically significant ($4.5{\pm}9.29$) in the pass group and the intermediate group, and was $29.7{\pm}11.49$ in the nonpass group of the formative evaluation (p<0.001). Using an FRFA could decrease the range in the standard deviation of the score and increase the minimum score among the subjects.
