Whether voluntary or involuntary in the field of education, learner participation is a basic premise for all teaching-learning. It is true that behaviorism and cognitive educational psychology have helped the development of teaching-learning theory so far but the reality is that it has not been of great help to provide learner-centered education according to the learner's learning type. We have professional theological knowledge and insight in theological college and having the knowledge to diagnose and solve difficulties and problems in the pastoral field and it is an increasingly difficult reality to educate students to have spiritual leadership that can lead the future society. We know that each student should understand the characteristics of each student and teach according to their learning type but the reason why it is difficult to implement is that each learner has different competencies, conditions, and cultural backgrounds and has particularly diverse learning types. in this respect, in order to increase the learning effect of individuals, individual learning considering the learning type of students is effective.

In multi-channel wireless sensor networks, optimizing data aggregation delay without any channels and timeslots conflicts has been concerned these days. The aggregation delay can be reduced by using different aggregation tree construction methods or scheduling in different methods in bottom-up or top-down manners. In this paper, we propose a new way of constructing aggregation tree purposing to decrease the total aggregation delay. The result shows that our proposed scheme can improve up to 64% comparing with state-of-the-art schemes.

Aggregating data with an optimal delay, which is a critical problem in Wireless Sensor Networks applications, is proven as NP-hard. In this paper, we focus on optimizing the aggregation delay by presenting an idea for channel and timeslot co-scheduling data aggregation in MWSNs. The proposed scheme, which names Break and Join, maximizes the number of sensor nodes to be scheduled in a working period, so that the overall number of working periods and data collection delay are reduced.

모바일 클라우드 서비스에 대한 요구에 따라 다양한 관련 기술들이 소개되고 있다. 이 중에서 모바일 원격접속 프로토콜은 RFB와 RDP, 두 개의 표준 프로토콜로 나뉜다. RFB 프로토콜은 구조의 단순함이, RDP 프로토콜은 빠른 응답속도가 상대적인 장점이다. 이 중, RDP 프로토콜은 윈도우즈 환경에 종속적인 제약이 있는데, SPICE 프로토콜은 이러한 RDP 프로토콜과는 달리 가상화 환경에 최적화된 오픈소스 프로토콜이다. 이러한 SPICE 프로토콜의 특징은 모바일 클라우드 환경에 상당한 이점을 가질 수 있다. 본 논문은 PC환경에서 RFB와 RDP, SPICE 프로토콜을 비교해 보고 모바일 환경에서의 활용성을 가늠해 본다. 그리고 모바일 환경에 가장 적합한 SPICE 프로토콜이 안드로이드에서 동작가능한지를 살펴보고 발생 가능한 문제점과 해결방안을 살펴보고자 한다.

스마트 장비의 발달로 장소와 환경에 상관없이 자유롭게 일을 할 수 있는 스마트워크가 중요한 이슈로 부각되고 있다. 이에 본 연구에서는 스마트워크의 개념 및 해외 동향을 살펴보고, 스마트워크가 활성화되기 위해 필요한 보안 방안에 대한 주요한 요건들에 대해서 살펴보았다. 스마트워크에서 안전성이 확보된다면 저 탄소 녹색성장을 포함하여 사회의 저 출산 고령화, 낮은 노동 생산성 등 당면 현안을 해결하는 방안으로 스마트워크가 유용하게 사용될 수 있다.

최근 화장품이나 뷰티산업의 성장이 가속화되고 있다. 이에 따라 시장에 다양한 뷰티제품들이 출시되고 있지만 그로 인해 오히려 본인에게 적합한 제품이 무엇인지 알지 못하는 경우가 많다. 온라인을 통해 구매하는 경우 구매후기 및 광고에 의지해야 하며 전문가의 조언을 구하기 위해서는 오프라인 상점을 방문할 수밖에 없다. 그러나 오프라인 상점을 방문한 경우에도 자신에게 적합한 화장품을 추천받는 것 또한 다분하지 않다. 본 논문에서는 이러한 문제점을 해결하고자 온라인 환경에서 소비자에게 맞는 상품의 광고 및 정보를 받을 수 있는 화장품 추천 서비스를 제안한다. 또한 제안서비스는 AI기능을 적용하여 기존의 방식보다 소비자 친화적인 서바스를 제공하는 것을 목표로 한다.

This study researched those universities for which fence opening and greening projects are being conducted by Seoul city. The forms of opened fences at 24 universities which have accomplished this project were classified into several types for each type of university, representative cases with many diverse facilities and active users were selected and investigated. The study was carried out using methods of field observations, literature review, and surveys. To maintain the confidentiality of the collected questionnaire analysis, the analysis of each type's usage frequency, overall satisfaction and a regression analysis with space environment and facilities, a one-way ANOVA for was used to validate the difference between types regarding satisfaction with the project. The results of usage type analysis were found to agree with the 3 analysis criteria-- installation location, user characteristics, and usage purpose--which were the legislative concepts. In overall satisfaction with facilities, it appeared that except for Seoul Women's College of Nursing with its rural district neighborhood type park, users were satisfied: with the small urban neighborhood park of Methodist Theological College, Konkuk University's small urban square park, and Sejong University's green space small city park. In general, users appeared to not have satisfaction with such features as fountains / hydroponic facilities, fitness facilities, and square facilities, which should be taken into consideration when pursuing further opening and greening projects. Regarding full satisfaction with the space environment, it was found that users were not satisfied with Seoul Women's College of Nursing's rural district neighborhood-style park, whereas they were satisfied with Methodist Theological College's small urban neighborhood park, Konkuk University's small urban square-style park, and Sejong University's green space small city park. In addition, it was shown that facilities use, convenience and privacy of the four parks were largely unsatisfactory for users, and that the small city parks located at roadsides were unsatisfactory regarding noise level, both of which should be most highly considered when conducting similar projects in the future.

The reliability of processing the distributed application becomes more and more important issues in distributed network as the usage of distributed network increases. Because the distributed network applications are processed in the available resources of Internet. It is important factors that the user can efficiently access the available resources and processed results can be delivered to the user of job request. Therefore in this paper, we suggested the survivability factor for sending data safely whether it can be efficiently accessed between the user and available resource which processes the distributed application. And evaluated the performance of the suggested factor using the data transmission time. Also we suggested the transmission algorithm for safe transmission using the survivability factor.

소프트웨어 정의 네트워킹(SDN)은 기존 네트워크의 컨트롤 기능을 컨트롤러에 중앙 집중화하여 프로그램 가능하며 유연한 네트워크 관리 방식을 제공한다. 컨트롤러-스위치 간 인터페이스 표준 기술인 OpenFlow에서는 스위치 내부의 플로우 테이블을 이용하여 네트워크에 접근하는 패킷을 처리한다. 하지만 OpenFlow 스위치에 주로 사용되는 TCAM의 부족한 용량으로 인해, 많은 트래픽이 발생하는 환경에서 플로우 테이블에 충분한 양의 플로우 엔트리를 설치하지 못하는 문제가 발생한다. 이 경우 플로우 테이블 오버플로우가 발생하는데, 네트워크에 새로이 진입하는 플로우를 위하여 기존의 플로우 엔트리를 방출시킬 필요가 있다. 이때, 활성화된 플로우 엔트리를 방출하게 되면 네트워크 컨트롤 오버헤드가 크게 증가할 위험이 있다. 따라서 오버플로우가 발생했을 때 어떤 플로우 엔트리를 방출시킬지 정하는 것이 중요하다. 이에 본 논문은 플로우 프로토콜 타입에 기반한 플로우 엔트리 방출 정책을 제안하여 효율적인 플로우 테이블 사용을 목표로 한다.
