The purpose of this research is to analyze ‘consumer education system in middle school’, whether it is suitably organized to help students make the right decision in their daily life as a rational consumer in this fast changing “the Informational Society”. We divided the consumer education of “the Informational Society” into 4 fields of studies(consumer information technique, decision making on purchasing, consumer financial management, and consumerism) and made specific analysis for this research. The “Technology & Home Economics” textbook which follows ‘The 7th curriculum’ conducted by “Korean Educational Board” Ministry of Education & Human Resources Development for first and second grade in middle school were used for this analysis. The results founded are as follows: first, for the curriculum analysis according to the 4 fields of consumer education, both the first and the second grade students' textbook had consumer information technique as the major portion of the consumer education. Second, as a result of the comparison between the two grade levels showed that the second grade level has higher portion of consumer education in “Home economics & Technology” textbook than the first grade level. Third, the present status of consumer education showed that the first grade level's consumer education was only limited in consumer information technique, but the second grade level's consumer education was ranging evenly throughout the 3 fields of consumer education: consumer information technique, decision making on purchasing and consumerism. These results of this study contribute to the development of an efficient and desirable curriculum for the adolescent' consumer education, specially for school consumer education, in “the Informational Society”.

지식을 축적하고 활용하기 위한 계속된 시도들이 '시맨틱 웹'이라는 개념에까지 이르게 되었는데, 시맨틱 웹이란 결국 인간의 지식을 정형화하겠다는 정보조직의 욕구에서 비롯된 산물로써, 인간이 언어로 표현하는 지식을 정형화하는 방법을 제시하고 이를 표준 웹 환경으로 통합하여 미래의 웹 환경을 일종의 통합된 목록시스템으로 구현하려는 노력이라고 볼 수 있다. 본 연구에서는 시맨틱 웹의 전반적인 개요와 시맨틱 웹을 구현하기 위한 기반인 RDF 스키마 및 여러 온톨로지 언어의 특징과 역할에 대해 살펴보고 몇가지 온톨로지를 기반으로 한 응용 연구를 소개하였다. 또한, W3C를 중심으로 시맨틱 웹을 위한 표준 온톨로지 언어로 제안된 OWL(Web Ontology Language)을 바탕으로 패싯형 시소러스인 AAT(Art and Architecture Thesaurus)의 개념 체계를 이용한 온톨로지 스키마를 구현하여 시맨틱 웹 환경의 온톨로지 기반 시스템의 구축사례로 제시하였다.

Recently, companies and organizations are becoming increasingly dependent on external resources to keep their competitive advantages under the turbulence of global business environmental changes. Therefore, they focus on the paradigm 'Open Innovation (OI)' which is reported as a convincing strategy to improve competitive advantage in terms of budget and time-to-market. The management of Incheon International Airport Corporation (IIAC) also considers the introduction of Open Innovation not only to adapt the business environmental changes but also to be devoted its social role as a public corporation. In this paper, we describe how we derived the promotion tasks for the introduction of OI and prioritized the tasks, performing our research on the IIAC Open Innovation. For these purposes, this research conducted the following three steps; the first stage for the analysis of current situation on the IIAC Open Innovation, the second stage for the elicitation of promotion tasks, and the last stage for the prioritization of the promotion tasks. In the first stage, critical success factors (CSFs) for open innovation introduction were derived from different research papers and case studies. In the following stage, promotion tasks were elicited from the IIAC based on the CSFs. In the last stage, the promotion tasks were evaluated on the base of criteria by using Analytic Hierarchy Process (AHP). And then the promotion tasks were grouped by the result of the evaluation. In this case, thirteen promotion tasks were derived for open innovation, ten promotion tasks except three inevitable promotion tasks were evaluated, and then they were grouped into four categories based on the importance-possibility analysis.

In wearable healthcare systems, sensor devices can be deployed in places around the human body such as the stomach, back, arms, and legs. The sensors use tiny batteries, which have limited resources, and old sensor batteries must be replaced with new batteries. It is difficult to deploy sensor devices directly into the human body. Therefore, instead of replacing sensor batteries, increasing the lifetime of sensor devices is more efficient. A transmission power control (TPC) algorithm is a representative technique to increase the lifetime of sensor devices. Sensor devices using a TPC algorithm control their transmission power level (TPL) to reduce battery energy consumption. The TPC algorithm operates on a closed-loop mechanism that consists of two parts, such as sensor and sink devices. Most previous research considered only the sink part of devices in the closed-loop. If we consider both the sensor and sink parts of a closed-loop mechanism, sensor devices reduce energy consumption more than previous systems that only consider the sensor part. In this paper, we propose a new approach to consider both the sensor and sink as part of a closed-loop mechanism for efficient energy management of sensor devices. Our proposed approach judges the current channel condition based on the values of various body sensors. If the current channel is not optimal, sensor devices maintain their current TPL without communication to save the sensor's batteries. Otherwise, they find an optimal TPL. To compare performance with other TPC algorithms, we implemented a TPC algorithm and embedded it into sensor devices. Our experimental results show that our new algorithm is better than other TPC algorithms, such as linear, binary, hybrid, and ATPC.

현대의 레이다는 위상 배열 안테나로 전자기파 빔을 생성하여 여러 가지 작업을 수행한다. 레이다가 수행하는 작업으로는 목표물의 탐지와 추적, 미사일 유도 등이 있다. 다기능 레이다가 개발되기 이전에는 레이다는 한 가지 작업만을 수행할 수 있기에, 각 작업을 수행하는 독립된 레이다가 필요했다. 하지만 다기능 레이다는 다양한 작업을 총괄하여 수행할 수 있는 기능을 탑재하고 있기 때문에, 하나의 레이다로 필요한 여러 작업을 수행할 수 있다. 레이다의 한정된 시간 자원을 효율적으로 이용하기 위해 예약된 작업을 적당한 순서로 나열하는 기법을 스케줄링이라고 한다. 본 연구에서는 두 가지의 스케줄링 기법들을 파악하여 효율적인 스케줄링 기법을 제시하여 보았다.

Background: Indonesia is one of the countries with the highest preterm birth rate. Preterm infants are more likely than term and normal weight infants to experience neonatal mortality and morbidity due to acute respiratory, gastrointestinal, immunologic, central nervous system, hearing, and vision problems. Kangaroo mother care (KMC) is a proven cost-effective intervention to help reduce mortality rates among preterm infants; however, it has not been fully implemented in hospitals. Purpose: Assess KMC knowledge and perceptions among health providers. Methods: This qualitative study was conducted from December 2015 to April 2016 and consisted of 21 in-depth interviews and 3 focus group discussions (FGDs). The 3 categories of health personnel in the study were clinical providers, hospital management representatives, and Indonesian Midwife Association members. Results: Most health providers know about the benefits of KMC including stabilizing temperatures, weight gain, and maternal-infant bonding and reducing human resources and labor costs. They were also aware of which newborns were eligible for KMC treatment. Their knowledge was mostly gained from observation or obtained from pediatricians and personal experience. They believed that a low birth weight infant in an incubator could not be treated with KMC and that it could only be practiced if a special gown was used when holding the baby. This perception could be caused by a lack of formal KMC training, leading to misunderstanding of its aspects. Conclusion: In conclusion, KMC knowledge of clinical providers in the 2 hospitals was sufficient, primarily due to their health-related educational background. Some perceptions could be potential barriers to or facilitate the implementation of KMC practice. These perceptions should be considered in future KMC training designs.
