최근 이질적인 하드웨어 특성을 고려한 IoT 응용 지원 프레임워크의 효율적인 프로그램 개발이 요구되고 있다. 또한, 인간의 뇌를 모사하여 스스로 학습 및 자율적 컴퓨팅이 가능한 뉴로모픽 아키텍처의 발전으로 하드웨어 지원의 범위가 넓어지고 있다. 하지만 기존 대부분의 IoT 통합개발환경에서는 AI(Artificial Intelligence) 기능을 지원하거나 뉴로모픽 아키텍처와 같은 다양한 하드웨어와 결합된 서비스 지원이 어렵다. 본 논문에서는 2세대 인공 신경망 및 3세대 스파이킹 신경망 모델을 모두 지원하는 AI 컴포넌트 추상화 모델을 설계하고 제안 모델 기반의 자율형 IoT 통합개발환경을 구현하였다. IoT 개발자는 AI 및 스파이킹 신경망에 대한 지식이 없어도 제안 기법을 통해 자동으로 AI 컴포넌트를 생성할 수 있으며 런타임에 따라 코드 변환이 유연하여 개발 생산성이 높다. 제안 기법의 실험을 진행하여 가상 컴포넌트 계층으로 인한 변환 지연시간이 발생할 수 있으나 차이가 크지 않음을 확인하였다.

This paper reports a noble instrument that helps physically disabled people to access computers. There have been numerous attempts to develop such a methodology, but most of them require an additional space for workstation often including access program installation. The additional space also needs to be carefully designed to consider each specific disabled area. This study aims to develop a system that removes the spacial limitation by putting the integrated computer interface using the wheelchair controller. The implementation of the computer workstation is performed by utilizing an USB interface. The developed equipment will take an important role to support various social lives for the users and eventually to improve their quality of life.

Integrated development environment (IDE) plays an important role in reducing the developm ent time, thereby improving software development productivity. In recent years, ubiquitous sensor networks (USNs) have become increasingly popular. However their application software is developed mostly using command-line-based tools. Such a development process is not only likely to be error-prone but also inconvenient to debug errors. This paper describes a novel IDE for USN application developers called Nano Esto that provides a single, consistent, and integrated environment for building and executing USN applications. The Nano Esto helps the developers edit and cross-compile source code and download the executable image to the program memory of sensor nodes with just a few button clicks. It also provides support for configuring an application-specific kernel, simulating a wireless sensor network, and estimating power consumption in each sensor node. Currently, Nano Esto runs on Linux as well as on Windows with the same look and feel.

Purpose: This study was conducted to identify resiliency factor, to test causal relationship and effect of resiliency factors on adaptation in families of children with cancer. A conceptual framework was constructed based on McCubbin's resiliency model. Hypotheses were tested with empirical data. Method: Data were collected using self-report questionnaire from 232 families of children with cancer. The collected data were analyzed using the SAS program and LISREL program for covariance structural analysis. Result: Family hardiness and problem-solving coping had significant direct effects on adaptation in families of children with cancer. Social support had significant indirect and total effect on adaptation. Family Schema had significant direct effect on family hardiness and problem-solving coping. Problem-solving communication had a significant direct effect on family hardiness and an indirect effect on family functioning and problem-solving coping. Among the resiliency factors, family hardiness had the greatest effect on adaptation in family of children with cancer. Conclusion: The findings suggest that nursing interventions to enhance family hardiness, problem-solving coping and social support would result in an increase in adaptation in families of children with cancer. An integrated intervention that emphasizes and promotes resiliency factors should be developed and established for families of children with cancer.

Because of the demands for high performance and high integrated system, the needs for optimal platform becomes more importance. Optimal platform can handle more data effectively with same resources. AMBA(Advanced Microprocessor Bus Architecture)$^{TM}$ defines on-chip communication standard for designing high performance embedded micro-controllers. It is consisted of AHB, ASB and APB. It can support fast implementation and reliability in system that is composed with reusable IPs. DMAC is one of master in system and generate master signals of AHB to communicate data from one slave(peripheral or memory) to another slave. It can reduce burden of CPU and increase system performance. We designed DMAC based on AMBA and it supports 13 Channels. Each channel can be controlled by software program. It decides channel's priority using round-robin method. It can support P2P, P2M, M2P and P2P communication.

Next-generation sequencing (NGS) is widely used to identify the causative mutations underlying diverse human diseases, including cancers, which can be useful for discovering the diagnostic and therapeutic targets. Currently, a number of single-nucleotide variant (SNV)-calling algorithms are available; however, there is no tool for visualizing the recurrent and phenotype-specific mutations for general researchers. In this study, in order to support defining the recurrent mutations or phenotype-specific mutations from NGS data of a group of cancers with diverse phenotypes, we aimed to develop a user-friendly tool, named mutation arranger for defining phenotype-related SNV (MAP). MAP is a user-friendly program with multiple functions that supports the determination of recurrent or phenotype-specific mutations and provides graphic illustration images to the users. Its operation environment, the Microsoft Windows environment, enables more researchers who cannot operate Linux to define clinically meaningful mutations with NGS data from cancer cohorts.
