인공지능의 사회적수용도가 증가하면서 머신러닝 기법을 기업에 적용하는 사례가 증가하고 있다. 머신러닝 기법의 선정에는 주로 정확성이나 해석 가능성 등 기술적 요인이 주로 기준이 되어왔다. 그러나 머신러닝 채택의 성공은 개발부서, 사용부서, 리더십과 조직문화 등 경영관리 요인도 영향을 주기도 한다. 아쉽게도 기술적 요인과 경영관리적 요인이 함께 고려된 머신러닝 선정의 성공 요인을 이해하는 통합 연구가 거의 존재하지 않는다. 이에 본 논문의 목적은 기업 내 머신러닝 선정을 이해하기 위해 John Rice의 algorithm selection process model과 task-technology fit, 그리고 IS Success Model 이론을 결합한 기술-경영관리 통합 모형을제안하고 실증적 분석을 하는 것이다. 머신러닝을 도입한 국내 기업 240곳을 대상으로 설문 분석을 실시한 결과 알고리즘 품질과 데이터 품질이 높을수록 문제-알고리즘 적합성에 높게 영향을 주는 것으로 나타났으며, 문제-알고리즘 적합성은 조직의 생산성과 혁신성에도 유의한 영향을 미치는 것으로 검증되었다. 또한 외주화와 경영진 지원이 머신러닝 시스템 품질에 긍정적인 영향을 미치고, 데이터 중심 경영 및 동기화와 같은 조직문화 요인은 활용성과에 높은 영향을 미치는 것으로 확인되었다.

The purpose of this study was to determine the strategies that middle school students used in solving problems concerning density and solubility. These were compared in the aspects of problem contexts for 42 students of varying logical reasoning ability, spatial ability, and learning approach. A coding scheme used consists of five categories: reading & organization, production, errors, evaluation, and strategy. Students' protocols were analyzed after intercoder agreement had been established to be .95. The results were as follows: 1. Students had more difficulties in reading and organizing the problems in everyday contexts than in scientific contexts. Students at the concrete-operational stage and / or surface approach were more likely to have difficulties in reading and organizing the problems than those at the formal-operational stage and / or deep approach. 2. Students tended to split up the solubility problems into sub-problems and to solve the density problem in everyday contexts in random manner. These were significantly correlated with the test scores concerning logical reasoning ability, spatial ability, and learning approach at the .1 level of significance. 3. Major errors in solving the density problems were to disregard the given information or generated and to use inappropriate information. Many errors in solving the solubility problems were found to be executive errors. The strategy to use the information given appropriately was positively related to students' logical reasoning ability, spatial ability, and learning approach. 4. More evaluation strategies were found in everyday contexts. Their strategies to grasp the meaning of answers and to check the math were significantly related to students' logical reasoning ability. 5. Students used the random trial-and-error strategy more than the systematic strategy and the systematic trial-and-error strategy, especially in everyday contexts. The strategies used by the students were significantly related to students' logical reasoning ability, spatial ability, and learning approach.

Objectives: This study aimed to analyze the textbook content, specifically that of the oral health units, of Korean elementary health textbooks in order to discuss oral health education in elementary schools through textbooks. Methods: The study analyzed the "oral health" units of six health textbooks for students in the fifth and sixth grades of elementary school in Korea. It identified the number of pictures, practice contents, and summaries in the textbooks, calculating the proportion of oral health units relative to the total number of pages in the textbook and comparing the learning goals provided by the WHO with the education contents. In addition, the study also analyzed several keywords from the textbooks in terms of whether they relate to oral health. Results: The comprehensive analysis on the oral health units within the three health textbooks analyzed revealed that all three were similar, except that the textbook from publisher A did not include an introduction. The three textbooks also had differences in terms of the organization of the contents. In terms of the learning goals of the oral health units, there were differences between the WHO standards and the learning goals from the textbooks, with the WHO standards only partially reflected. The analysis also showed that there were more keywords on oral diseases than those related to oral health management and prevention. Conclusions: Improvements should be made regarding the learning goals and education topics of health education in order to ensure that children receive a more systematic oral health education in their earlier years, which will help to develop and correct oral health management habits among elementary school students.

This study was intended to survey and analyze the illustrations of the elementary science textbooks in the』 7th revised education curriculum in Korea, and to compare the results with the illustration organization of the elementary science textbooks of Japan. The analysis criterion was composed of two categories, the kind of illustration and the role of illustration. The kind of illustration was divided into five subcategories such as photograph, picture, illustration, cartoon and diagram. The role of illustration was divided into four subcategories such as motive induction, guidance for learning, the supply of material, the presentation of results. According to the analyzing criterion, the frequencies of relevant subcategories of illustrations in science textbooks were checked and arranged and the resultant data were analyzed by grades. The findings of this study were as follows: 1. Korean science textbooks have about 3.29 illustrations per page whereas Japanese ones have 4.1l. Compared with Korean science textbooks, Japanese ones have more illustrations. 2. From the analysis of the kinds of the illustrations by grade basis, it was found that the order of percentage of illustrations is photograph, cartoon and picture in both countrys' science textbooks. Korean ones are highly dependent on photograph. As a contrast Japanese ones have more ratio of cartoon and picture than Korean science textbooks. 3. The analysis of the roles of the illustrations by grade basis showed that the role of guidance for learning is major in both countrys' science textbooks. The role of guidance for learning is prominent in Japanese ones, but in Korean ones, the role of guidance for learning is a little higher than that of the supply of material.

The prevalence of metabolic syndrome (MS) in the nonobese population is not low. However, the identification and risk mitigation of MS are not easy in this population. We aimed to develop an MS prediction model using genetic and clinical factors of nonobese Koreans through machine learning methods. A prediction model for MS was designed for a nonobese population using clinical and genetic polymorphism information with five machine learning algorithms, including naïve Bayes classification (NB). The analysis was performed in two stages (training and test sets). Model A was designed with only clinical information (age, sex, body mass index, smoking status, alcohol consumption status, and exercise status), and for model B, genetic information (for 10 polymorphisms) was added to model A. Of the 7,502 nonobese participants, 647 (8.6%) had MS. In the test set analysis, for the maximum sensitivity criterion, NB showed the highest sensitivity: 0.38 for model A and 0.42 for model B. The specificity of NB was 0.79 for model A and 0.80 for model B. In a comparison of the performances of models A and B by NB, model B (area under the receiver operating characteristic curve [AUC] = 0.69, clinical and genetic information input) showed better performance than model A (AUC = 0.65, clinical information only input). We designed a prediction model for MS in a nonobese population using clinical and genetic information. With this model, we might convince nonobese MS individuals to undergo health checks and adopt behaviors associated with a preventive lifestyle.
