Purpose : The purpose of this study was to investigate the effectiveness of cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) education for school teachers by questionnaire survey including the knowledge, self-efficacy and skills of CPR and AED after basic life support (BLS) education. Methods : The subjects were school teachers who participated in BLS education from 24 Nov. to 1 Dec. 2012. They completed the self-reported questionnaire based on BLS skill checklist. Results : There was a statistically significant increase in the knowledge(p <.001), self-efficacy (p <.001) and skills(p <.001) of CPR and AED after BLS education. The correlation existed conspicuously between knowledge versus self-efficacy(r =.409, r =.387), knowledge versus skill(r =.442, r =.084), and self-efficacy versus skills (r =-.148, r =.047) of CPR and AED before and after BLS education. Conclusion : After BLS education, most of the participants found the program was easy and useful to perform. Participants had the willingness to do CPR and AED and wanted to teach BLS to others. It is necessary to provide BLS education for school teachers by systematic approach.

Purpose: The purpose of this study was to improve the quality of prehospital care provided to infants and toddlers (preschoolers) based on questionnaire findings. Methods: A total of 1,634 running sheets from 119 centers of D city from patients older than 1 month and less than 7 years of age from January 1, 2013 to December 31, 2013 were reviewed for 119 emergency medical technicians (EMTs) activity analysis. And a self-reported questionnaire about knowledge and competency in prehospital care of preschoolers was completed by 159 EMTs at fire stations in D city. Data were analyzed using IBM SPSS Statistics for Windows, Version 21.0. Results: Of 1,634 patients, 58.6% were call to 119 due to disease, 33.8% due to injuries and 7.5% due to traffic accident. Knowledge and confidence in treating preschoolers was significantly higher among paramedic EMTs than basic EMTs. The 119 EMTs surveyed indicated that training for preschooler prehospital care was most needed. Conclusion: In order to provide high quality prehospital care for preschoolers transported to emergency rooms, it is necessary to equip ambulances with the proper equipment. In addition, EMTs should be provided educational opportunities and clinical training.

Ubiquitous Healthcare (u-Healthcare) is the intelligent delivery of healthcare services to users anytime and anywhere. To provide robust healthcare services, recognition of patient daily life activities is required. Context information in combination with user real-time daily life activities can help in the provision of more personalized services, service suggestions, and changes in system behavior based on user profile for better healthcare services. In this paper, we focus on the intelligent manipulation of activities using the Context-aware Activity Manipulation Engine (CAME) core of the Human Activity Recognition Engine (HARE). The activities are recognized using video-based, wearable sensor-based, and location-based activity recognition engines. An ontology-based activity fusion with subject profile information for personalized system response is achieved. CAME receives real-time low level activities and infers higher level activities, situation analysis, personalized service suggestions, and makes appropriate decisions. A two-phase filtering technique is applied for intelligent processing of information (represented in ontology) and making appropriate decisions based on rules (incorporating expert knowledge). The experimental results for intelligent processing of activity information showed relatively better accuracy. Moreover, CAME is extended with activity filters and T-Box inference that resulted in better accuracy and response time in comparison to initial results of CAME.

The widespread use of location-based services (LBSs), which allows untrusted service provider to collect large number of user request records, leads to serious privacy concerns. In response to these issues, a number of LBS privacy protection mechanisms (LPPMs) have been recently proposed. However, the evaluation of these LPPMs usually disregards the background knowledge that the adversary may possess about users' contextual information, which runs the risk of wrongly evaluating users' query privacy. In this paper, we address these issues by proposing a generic formal quantification framework,which comprehensively contemplate the various elements that influence the query privacy of users and explicitly states the knowledge that an adversary might have in the context of query privacy. Moreover, a way to model the adversary's attack on query privacy is proposed, which allows us to show the insufficiency of the existing query privacy metrics, e.g., k-anonymity. Thus we propose two new metrics: entropy anonymity and mutual information anonymity. Lastly, we run a set of experiments on datasets generated by network based generator of moving objects proposed by Thomas Brinkhoff. The results show the effectiveness and efficient of our framework to measure the LPPM.

In recent environment of dynamic management, there is growing recognition that information and knowledge management systems are essential for efficient/effective decision making by CEO. To cope with this situation, we suggest the Data-Miming scheme as a key component of integrated information and knowledge management system. The proposed system measures business performance by considering both VA(Value-Added), which represents stakeholder’s point of view and EVA (Economic Value-Added), which represents shareholder’s point of view. To mine the new information & Knowledge discovery, we applied the improved genetic algorithms that consider predictability, understandability (lucidity) and reasonability factors simultaneously, we use a linear combination model for GAs learning structure. Although this model’s predictability will be more decreased than non-linear model, this model can increase the knowledge’s understandability that is meaning of induced values. Moreover, we introduce a random variable scheme based on normal distribution for initial chromosomes in GAs, so we can expect to increase the knowledge’s reasonability that is degree of expert’s acceptability. the random variable scheme based on normal distribution uses statistical correlation/determination coefficient that is calculated with training data. To demonstrate the performance of the system, we conducted a case study using financial data of Korean automobile industry over 16 years from 1981 to 1996, which is taken from database of KISFAS (Korea Investors Services Financial Analysis System).

본 연구에서는 웹기반 멀티미디어 정보환경에서 자원관리 패러다임 변화와 함께 도서관의 장서관리가 지식컨텐츠관리로 변화할 필요성을 제시하였다. 효율적인 웹 컨텐츠관리는 개인별 맞춤화 서비스를 제공함으로서 궁극적으로 이용자 만족을 최대화 할 수 있다. 특히, 메타브라우징 방식을 이용한 컨텐츠 맞춤화 서비스는 이용자 개인이 일하는 핵심컨텐츠만을 집중 서비스함으로서 이용자 만족의 극대화에 기여한다. 본 연구에서는 이와같이 이용자의 만족을 강화하기 위한 웹 기반 멀티미디어 지식컨텐트 관리방안에 대해서 관리요소와 서비스방안을 중심으로 연구하였다.

This study was carried out to investigate the present status of nutrition services for infants in public health centers and the need for nutrition services of health workers and infants mothers. The study subjects were 146 health workers and 197 infants mothers. The results were as follows : At present, the only major nutrition services for infants were vaccination and dental care. Proper nutrition management services were available to infants. Nutrition knowledge scores were 16.8 for health workers and 15.3 for mothers out of 20 possible points. Health workers strongly demanded a well-organized nutrition education program, government support, audio-visual materials and the employment of a community nutritionist. The public health workers, in particular, demanded the development of education programs for breastfeeding and weaning. The infants mothers demanded services of nutrition information and teaching of cooking and menu planning. Based on this, the results suggest that the employment of a community nutritionist and the development of practical nutrition service programs for infants are needed very urgently for public health centers.
