Today, the advance of a community tool such as a SNS enables users to easily share information each other and quickly deliver various opinions to suppliers. The suppliers are trying to create new value through co-creation strategies in order to satisfy rapidly and variously changing user's needs. User-participation-based idea platforms are emerging as a open innovation space that can provide user participation and interaction between suppliers and users. However, although each idea platform has specific advantages in each stage of a development process, this development process is not generalized as one complete, integrated development process. Thus, the development of an effectively integrated process, which includes advantages in each stage of the process, is needed. This research aims to analysis the characteristics of idea platforms based on the classification of idea platforms as a basic study for proposing a new development processes of them. This research will contribute to the guideline for developing a new user-participation-based idea platform.

2020학년도 1학기는 외부 환경 요인으로 인해 대학교육시스템에 큰 변화가 발생한 시기라고 할 수 있다. 컴퓨터공학 분야의 대표적인 실습기반 교과목인 프로그래밍 수업에서 학습자들에게 온라인 수업이지만 대면 수업의 실재감을 제공하는 방법을 모색할 필요성이 대두되었다. 본 연구에서는 다양한 유형의 수업 방식을 온라인 수업에 활용하여 대면 수업 수준의 실재감을 학습자에게 제공하고 학습효과를 높이고자 하였다. 강의 동영상 수업과 상호작용을 포함한 실시간 수업을 혼합하여 수업한 후 설문 조사를 통해 실시간 수업을 선호하는 학습자들이 수업목표인 프로그램 개발 능력을 타 학습자들보다 잘 습득하여 수업 만족도가 높았고, 이를 통해 온라인 수업에서 실시간 수업이 능동적인 학습자들에게는 대면 수업과 동등한 수준의 학습 효과가 있었음을 조사·분석하였다.

The purpose of this study is to examine difference of information processing style on lesson comprehension scores and usability ratings in e-Learning containing visual information structure. To address this goal, 68 university students were participated in this research. They were asked information processing style test, lesson comprehension test, and usability ratings after completed e-Learning lesson. According to the result, there was not significant difference between visual and verbal information process style on lesson comprehension as learn outcomes. However, students who are visual information processing style were significantly higher ratings than students who are verbal information processing style on 4 of 8 usability scales; awareness of lesson structure, awareness of lesson length, ease of navigation, and ease of lesson learning. These result indicate that there will be needed the design of aptitude treatment interaction for e-Book according to information processing style.

This study examines the subjective perception of software developers on happiness at work through the Q-sort methodology. Analysis of 63 respondents revealed four types happiness at work with highly differentiated characteristics: 'stability of work oriented', 'defiant self-driven, technology-oriented', 'realistic professionalism oriented', and 'genuinely technology and task-immersion oriented'. The 'defiant self-driven, technology-oriented' and 'genuinely technology and task-immersion oriented' types are interested in latest ICT and consider recognition of one's professionalism as well as self-realization result in happiness at work. On the other hand, the 'stability of work oriented' and 'realistic professionalism oriented' types did not pay much attention to one's growth of technical career but emphasized salary, welfare benefits and job promotion as the most important factors in happiness at work. Today, extraordinary SW developers are a key factor to acquire industrial competitiveness. Nations and corporations should prepare realistic ways to promote overall happiness at work by accurately understanding the varying characteristics and predisposition of domestic ICT personnel. In Korea, it is found that there is a shortage of 'genuinely technology and task-immersion oriented' SW developers. In order to secure national and industrial competitiveness in the era of the Fourth Industrial Revolution, creation of work ecosystem to promote high levels of happiness at work is required to secure quality software production and pride as an ICT professional.

기존의 교육 시스템은 그 특성상 온라인 교육 시스템의 보완적인 요소로써 혹은 독창적인 특성을 직간접적으로 도입하고 있다. 온라인 교육 시스템의 역할이 확고해지는 과정에서 다양한 연구 결과를 적용하여 도입 초기에 비해 많은 발전을 보이고 있다. 본 논문에서는 온라인 교육 시스템을 개발한 개발자와 학습자 간의 문의형 상호작용 유형을 채택하에 개발자가 상호작용의 내용을 만들고 학습자에 의해 교육 내용의 전달 과정을 주도하는 과정에서 학습 효과를 높이기 위해 기존의 에이전트 기반 학습시스템에서 발생할 수 있는 단순 적용성을 개선한 에이전트 기반 문의형 온라인 교육 시스템을 제안한다.

This study proposes an information retrieval method reflecting the user's preferences based on the fuzzy set theory to develop information contents which support pedestrian's navigation. Firstly, the research evaluated subjects' preferences on commercial spaces set to a hypothetical destination. Also it surveyed the causal relationship between the visual characteristics and the emotional characteristics to propose methods of Navigation Knowledge Base (NKB). The NKB was composed of three elements; 1. the correlation model between emotional characteristics, 2. the causal relationship between visual characteristics and emotional characteristics, 3. the transformation model between visual characteristics and the physical characteristics. Secondly, this study classified the pedestrian's destination search into 4 types with his or her preferences and the time conditions limited during navigation. For each type it presented the Destination Search Algorithm (DSA). Finally, the research simulated the destination search in 4 navigation types using NKB and DSA and verified the availability of the information retrieval method reflecting pedestrian's preferences. In conclusion, the proposed information search method will be applied to reflect the user's preferences to develop information appliances.

Botnet은 공격자의 명령을 받아 공격을 수행하는 Bot과 bot을 관리하는 서버(혹은 peer)로 이루어진 네트워크이다. 유선 네트워크 상에서 Botnet을 탐지하기 위해서 많은 메커니즘이 제안되었지만 6LoWPAN과 같은 IP 기반의 센서네트워크 상에서 Botnet의 유형이나 탐지법에 대해서는 제안된 메커니즘이 없었다. 본 논문에서는 6LoWPAN 환경에서 Botnet의 공격 유형과 탐지법을 제안하고 구현 사례를 설명한다.

The purpose of this study is to find out subjective perception types and needs of interested group on manpower training system with long-term care service by Q methodology, then to search for political measures to improve long-term care system in the implication of the sorted subjective perception types. The result of the study showed that there are five major sorts of subjectivities on manpower training system with long-term care service: emphasizes retraining of existing care worker(Type1), emphasizes ethics of public service provider(Type2), emphasizes practice-oriented education(Type3), emphasizes policy judgement of government(Type4), emphasizes training of long-term care worker in demand(Type5). And to try quantity approach methods, this study was developed Q-Block as a assessment tool to enhance validity and reliability of Q-types. The results of the survey showed high conformity.

This study studied on innovation and R&D performance measurement, and especially the dimensions of measuring performance. The Empirical study is based on the opinions of 169 experts from a R&D group with a career for SMBA's support. The results reveal that what the most optimal and appropriate measures of project-level success are will depend on the type of innovation involved and the development project type and the relatively low significance of financial measures for innovation projects in general. Additionally, measurability is not major significance factor for selecting measures, whereas the level of innovativeness were to be selected as important factor. The roles of the evaluators are affected. It is expected to help make government policy for R8D performance evaluation.

In component based development, component modeling for understanding and analyzing is the important part and is used to improve reusability. Generally, components are need to be divided into two types according to their usages, where the developer and assembler are usually different. To make a good component model, a complete component and interface specification for those components are needed. And the component model needs to adept two different views of developer and assembler. In this paper, we suggest two different views of component model that is related to views from developer and assembler, and we expand UML. Also we validate the efficiency of the suggested model by developing and applying a tool for building, managing and automatic transformation.
