The manner in which education will be delivered in the 21st-century has often been debated. Various literature has agreed that an interactive teaching and learning method is required in parallel with the emergence and development of cyber technology. The conventional method of teaching should be reconstituted to emphasize aspects associated with innovation and creativity in attracting the attention of students in learning. Despite the current Malaysian education emphasize the learning features that include 1) Creative thinking, 2) Critical thinking, 3) Collaboration, 4) Character and 5) Communication. However, 21st-century approach requires exposure, skills, and creativity to be implemented by the Malaysian educators. Therefore, the aim of this study is to propose a new maritime interactive teaching model towards a Sustainable Development Goals (SGDs) and industrial revolution 4.0. Three (3) secondary schools around Terengganu in Malaysia were chosen to participate in a pilot case study. The results of the study found that more than 90% of students now understand more about the maritime industry based on their acquired knowledge and education in this area. While, more than 70% of students described that this method of teaching is appealing. Maritime education innovative learning through an interactive learning model was successfully achieved based on the findings of this study, called the ‘Mariner’s Fantasy’. Additionally, through the inspirations of IR 4.0 and the Malaysia Education Development Plan, 2013-2025, the study has demonstrated the usefulness of the Maritime Education Innovative Learning (MEIL) program through an interactive learning method, in enhancing the delivery of maritime education by adopting an effective teaching-based approach.

Combination between tissue engineering and other fields has brought an innovation in the area of regenerative medicine which ultimate aims are to repair, improve, and produce a good tissue construct. The availability of many types of scaffold, both synthetically and naturally have developed into many outstanding end products that have achieved the general objective in tissue engineering. Interestingly, most of this scaffold emulates extracellular matrix (ECM) characteristics. Therefore, ECM component sparks an interest to be explored and manipulated. The ECM featured in human amniotic membrane (HAM) provides a suitable niche for the cells to adhere, grow, proliferate, migrate and differentiate, and could possibly contribute to the production of angiogenic micro-environment indirectly. Previously, HAM scaffold has been widely used to accelerate wound healing, treat bone related and ocular diseases, and involved in cardiovascular repair. Also, it has been used in the angiogenicity study, but with a different technical approach. In addition, both side of HAM could be used in cellularised and decellularised conditions depending on the objectives of a particular research. Therefore, it is of paramount importance to investigate the behavior of ECM components especially on the stromal side of HAM and further explore the angiogenic potential exhibited by this scaffold.

본 논문에서는 계층적 무선 센서 네트워크를 위한 그룹기반 보안 메커니즘을 제안한다. 이를 위해 세 가지 형태의 노드(베이스 스테이션 그룹 관리 노드 센서 노드)로 구성된 3계층 센서네트워크에서 안전한 라우팅을 위한 구조를 설계한다. 그룹기반 배치는 가우시안(Gaussian) 분산을 이용하여 수행되며, 제안된 모델을 사용해 85% 이상의 네트워크 연결이 가능하다. 이미 보안 기능을 공유하고 있는 작은 그룹들은 안전한 그룹을 형성하고, 그룹 관리 노드들은 전체 네트워크의 백본을 형성한다. 본 논문의 보안 메커니즘은 배치된 센서 그룹에서 수집된 데이터를 처리하기 위해 제안되었으며, 관리노드에 의해 수집된 센싱 데이터는 다른 관리노드를 거쳐 베이스 스테이션에 전달된다. 제안된 메커니즘은 경량화 되었고, 노드 캡쳐 공격에 강력하게 대응할 수 있으며 분석 자료와 시뮬레이션을 결과를 통해 이러한 특징을 확인할 수 있다. 또한, 분석 자료를 통해 그룹 관리노드와 센서 노드가 조밀하게 배치되었을 때 안전성이 크게 향상됨을 알 수 있다. We propose a group-based security scheme for hierarchical wireless sensor networks. We model the network for secure routing with 3-tier sensor network comprised of three types of nodes: Base Station, Group Dominator and ordinary Sensor Nodes. Group-based deployment is performed using Gaussian (normal) distribution and show that more than 85% network connectivity can be achieved with the proposed model. The small groups with pre-shared secrets form the secure groups where group dominators form the backbone of the entire network. The scheme is devised for dealing with sensory data aggregated by groups of collocated sensors; i.e., local sensed data are collected by the dominating nodes and sent an aggregated packet to the base station via other group dominators. The scheme is shown to be light-weight, and it offers a stronger defense against node capture attacks. Analysis and simulation results are presented to defend our proposal. Analysis shows that robustness can significantly be improved by increasing the deployment density using both the dominating and/or ordinary sensor nodes.
