In this study, learning preferences of the informatics gifted participating in on-line programming practice has been investigated and the tutoring strategy based on learning styles was developed and verified its effectiveness. On-line programming learning is the environment in which learning is done through interaction with a tutor. For determination of the students' learning styles, Grasha-Reichmann's learning style was utilized. Key elements, learning activity and feedback, of tutoring strategy were derived based on learning style and developed on-line programming learning tutoring strategy. To verify the effectiveness, six-class period of learning C-language of 173 middle and high school students based on learning styles was applied for 12 weeks. As a result, the experiment group applied with a tutoring strategy based on the learning style showed significant improvements in terms of satisfaction and achievement than the control group.

콘텐츠 유통시장의 변화 움직임을 수요, 공급, 기술의 세 가지 측면에서 살펴보고 방송 선진국인 미국의 온라인 비디오사업자 '빅 3'의 비즈니스 모델을 비교 설명한다. 이어서 본론에서는 Netflix의 경영전략을 콘텐츠 확보전략과 해외시장 경영전략으로 나누어 조사해 본다. 그 결과 오리지널 콘텐츠 확보능력과 해외시장의 가입자 증가가 Netflix의 주요 핵심역량인 것으로 나타났다. 이를 통해 알아낸 사실은 다음과 같다. 첫째 Netflix의 성장 추진동력은 그들이 제공하는 서비스, 콘텐츠, 마케팅이며, 기술적으로는 인터넷망의 발전과 디바이스의 진보에 힘입은 바 크며 둘째, Netflix의 성장을 저해하는 요소는 시장포화, 서비스를 개선하는 경쟁사업자의 증가이며, 셋째 사람들은 재미있는 콘텐츠를 찾아 끊임없이 움직일 것이므로 Netflix를 포함한 온라인 콘텐츠 유통시장에서는 격심한 경쟁이 예상됨을 알 수 있다.

This paper compares and analyzes the domestic OTT services to access their success factors, strategies and examine the domestic OTT leader's wavve's unique differentiation strategy. It is a comparative study of the top five market share services based on the operator and content's key success factors criteria, revenue structure, personalization, interactive media and cooperation. As a result, the common success factors were contents that reflected the characteristics of the operators, hybrid VOD, hybrid filtering, real-time participation interaction, alliances between the same and heterogeneous industries, and utilization of existing business areas. In addition, the study confirmed that it expanded the scope of the project and operated the contents efficiently by introducing one or more business strategies. wavve has been widely validated with its content, while B2C has long-term benefits and overseas use services, and B2B has a systematic use system, differentiating itself from other services. This paper can be the foundation for identifying the strengths and differences of each service on 2021, entering the domestic OTT industry, and establishing competitive strategies.

This paper researches the value of domestic telecommunication bundle products. Customers evaluate each telecommunication products differently according to their attributes. The attributes affecting the customer value of telecommunication bundling can be categorized in 3 ones as follows; corporate image, service feature, and service price. Also authors analyze the difference of importancy that customers consider when they evaluate each products, and propose the optimal scenario for bundling. In conclusion, other two companies A, C excluding B should invest more resources into the portion that strengthen the attributes of company image, and service feature to upgrade their 'corporate image', and 'service feature'. According to 6-scenarios analysis on the bundle products, the QPS expansion of company A was the most advantageous position, but if companies B, C expand DPS made use of their strengths, they can prevent from decreasing additivity rapidly with sequential scenario. The above results show that one company may have equable power in each area, but if another company having strengths in special areas makes up for its weakness and differentiates gradually it can contribute to strengthen its competitiveness. This contributed much more theoretical and practical than the existing researches. Supposing that additivity index evaluated by consumers can be changed by efforts of companies, this scenario planning is the result of study showing that the investment and publicity of each company have to be considered as its characteristic of each product at the same time.

This study aimed to find health related lifestyle factors that influence glycemic control for diabetes mellitus (DM) management strategies. This study used nested case-control design with matching variables that were not controlled by individuals such as age, sex, insulin or oral hypoglycemic agent (OHA) use, disease duration, education level and household income. This study analyzed 983 subjects with type 2 DM who enrolled in the $7^{th}$ (2016-2017) Korean National Health and Nutrition Examination Survey (KNHANES). The target HbA1c level of controlled glucose was defined as less than 6.5%, and 289 (30%) were achieved. Conditional multivariable logistic regression analysis was performed to find self-control factors associated with HbA1c levels. The results statistically significant for variables such as duration of diabetes, insulin or OHA use in overall cohort and body mass index (BMI), smoking and fundus Examination in matched cohort. These results are expected to provide as evidence for the intensive care criteria(disease duration, drug use) and lifestyle management strategy(BMI, smoking, fundus examination).

The purpose of this study was to develop teaching stratege focused on Conservational reasoning, Proportional reasoning, Variable-controlling reasoning, Probabilitic reasoning, Correlational reasoning, Combinational reasoning and investigate its effects on enhancing students' logical thinking skills through the science teaching on common education. And the teaching materials was implemented to 110 students in middle school over about six months. The results indicated that the experimental group presented statistically meaningful improvement in logical thinking skills (p<05). Especially, this teaching stratege was effective on Conservational reasoning, Variable-controlling reasoning, Combinational reasoning but was not effective on Proportional reasoning, Probabilitic reasoning, Correlational reasoning (p<.05). Logical thinking according to the teaching strategy skill was not affected by gender, cognitive level, academic achievement (p<.05).
