Extended life expectancy and a decrease in fertility rates are dramatically increasing the number of seniors who will eventually need professional care assistance. Although there is no clear technical solution to this problem, recent advances in ubiquitous computing offer opportunities to assist elders in their residence, thus reducing the need for professional assistance in special facilities. There have been several studies, but current solutions tend to address specific issues and cannot be easily extended, updated, and customized to meet the complex and evolving requirements of eldercare assistance. This study aims to bridge this gap, and this paper presents a context-management framework, called awareness for pervasive environments (APE), that provides easily customizable support for the development of ubiquitous eldercare services and applications.

The purpose of this study was to show the abnormal eating habit in pervasive development disorder (PDD) children. The authors studied retrospectively the features of eating habit in 60 PDD children diagnosed by DSM-III-R who made their first visity to Department of Psychiatry, Dongsan Medical Center Keimyung University, from January 1990 to December 1990. The results were as follows;1. The average was 3 years, onset age of illness was before 3 years of all patients, and the ratio between male and female was 5,7:1, and ratio between autistic disorder and PDDNOS was 4:1. 2. Twenty four of 60 PDD children had one or more abnormal eating habit(autistic disorder; 43.8%, PDDNOS; 25%), and more prevalent to male(43.1%,) than female(22.2%). 3. Milk, biscuit, meat and fluids were the favorate foods, the unfavorate foods were vegetable, rice, frutis. 4. Patients of abnormal eating habit were more symptoms of DSM-III-R on 'lack of awareness', 'preoccupation with parts of objects','distress over change'and 'insistence on routine' than others.

편재형 컴퓨팅(pervasive computing)에서 컨텍스트에 대한 중요성은 점점 강조되고 있다. 편재형 컴퓨팅(pervasive computing) 환경에서 다양한 디바이스들은 사용자의 상황에 가장 적절한 서비스를 제공하기 위해 통신할 필요가 있는데, 특히 센서는 컨텍스트 데이터를 얻는데 효과적이다. 컨텍스트 정보를 얻기 위해 사용되는 센서들은 물리적인 센서들로부터 가상 센서까지 여러 가지가 있는데, 이러한 다양한 센서들을 관리하기 위해 센서 프레임워크가 필요하다. 본 논문에서는 모바일에서의 센서 어플리케이션 표준인 JSR256을 기반으로 한 센서 프레임워크를 어플리케이션 개발자의 시각이 아닌 센서 개발자의 시각에서 분석하였다. 그리고 관련 문제점을 발견하여 다양한 센서들을 효율적으로 관리하고 새로운 센서 모듈을 용이하게 개발할 수 있는 센서 프레임워크를 제안하고 제시된 센서 프레임워크를 통한 재사용성을 검증해 보았다.

Organizations today depend and thrive on timely, accurate and strategically relevant information. Business analytics (BA) holds the key to many of these issues. This paper validates a model on how the usage of BA leads to operational efficiency. We identified the factors of basic analytical usage from the Business Capacity Maturity Model (BCMM). The scope of the study is restricted to the Information Technology Infrastructure and Application management domain. A survey was conducted among the managers of the IT companies in Bengaluru, India. The results showed a significant influence of data-oriented culture and BA tools and infrastructure on BA usage. We found a significant influence of BA usage and pervasive use on operational efficiency. The speed to insight is still not practised in organizations. The awareness level of analytical skills in organizations is very low.

In this paper, we designed micro-structured electromagnetic transducers for energy harvesting and verified the performance of proposed transducers using finite element analysis software, COMSOL Multiphysics. To achieve higher energy transduce efficiency, around the magnetic core material, three-dimensional micro-coil structures with high number of turns are fabricated using semiconductor fabrication process technologies. To find relations between device size and energy transduce efficiency, generated electrical power values of seven different sizes of transducers ($3{\times}3\;mm^2$, $6{\times}6\;mm^2$, $9{\times}9\;mm^2$, $12{\times}12\;mm^2$, $15{\times}15\;mm^2$, $18{\times}18\;mm^2$, and $21{\times}21\;mm^2$) are analyzed on various magnetic flux density environment ranging from 0.84 T to 1.54 T and it showed that size of $15{\times}15\;mm^2$ device can generate $991.5\;{\mu}W$ at the 8 Hz of environmental kinetic energy. Compare to other electromagnetic energy harvesters, proposed system showed competitive performance in terms of power generation, operation bandwidth and size. Since proposed system can generate electric power at very low frequency of kinetic energy from typical life environment including walking and body movement, it is expected that proposed system can be effectively applied to various pervasive computing applications including power source of embodied medical equipment, power source of RFID sensors and etc. as an secondary power sources.

Multiple areas of development are affected in pervasive developmental disorders(PDD), and assessments of various aspects of behavior and development are essential for diagnosis. The object of this review is to provide the practical guidelines for the assessment of core features of PDD, including abnormalities in communication, social interaction, and repetitive and stereotyped behavior. It covers the issues of differential diagnosis within and outside the PDD category, standardized diagnostic tools, assessment of intellectual and language functions, and the early diagnosis of PDD in infancy. This guideline also stresses the process of medical and neurological evaluation for proper diagnosis of PDD.

The new research data and rapid development of psychotropic drugs over the past few years have warranted the development of clinical practice guidelines for managing pervasive developmental disorder(PDD). These guidelines are urgently needed due to the recent changes in social circumstances and clinical situations in Korea. Despite the many limitations and problems surrounding the development of these guidelines, the Korean Academy of Child and Adolescent Psychiatry(KACAP) has decided to develop the Korean Practice Parameters for the Treatment of PDD. The goal, basic principles, organization, and implications of this development project are introduced in this special paper. We expect these practice parameters to be a useful reference not only for child psychiatrists and other healthcare professionals in clinical practice, but also for the autistic patients themselves and their caregivers. The practice parameters shall be revised and improved in the near future.

With the emergence of pervasive computing, personalization becomes an important issue to provide with users customized services, anywhere and anytime in their specific environment. Many researches have shown the possibilities of personalization by acquiring and processing sensor information around users. However, personalization remains still at its infancy, since most researches have failed to consider various contexts comprehensively besides sensor data, and just developed tailored services for a specific application domain. In this work, we propose a simulation-based CAS (context Aware Web Services) development methodology. Our methodology considers various contexts on users (eg. current location), web services (eg. response time), devices (eg. availability) and environment (eg. sensor data) all together by simulating them on the fly for personalized and adaptable services.
