Wireless Sensor Networks(WSN)기반의 Border Surveillance Networks(BSN)는 다양한 제한조건을 동반하며 침입 혹은 환경 등을 감시함을 목적으로 하고 있기 때문에 이벤트 발생시 신뢰적인 데이터 전송은 매우 중요한 부분을 차지하게 된다. 본 논문에서 적용한 대표적인 요구기반 라우팅 방법인 Ad hoc On-demand Distance Vector Routing(AODV)는 BSN 에 적용하였을 경우 홉 수(Hop Count)를 메트릭으로 최적의 경로를 계산하고 선택하여 Uni-Path 로 데이터를 전송하게 된다. 이때 AODV 는 Uni-path 로 데이터 전송을 진행하게 되며 링크의 단절이 빈번히 발생하는 BSN 의 환경적 요인으로 데이터 전송의 신뢰성이 감소하게 될 것이며 이는 비효과적인 데이터 전송을 야기하게 된다. 따라서 본 논문에서는 Multi-path 개념을 도입하여 데이터 전송 시 링크단절에 의해 발생 하는 시간의 지연을 줄이고 더욱 신뢰성 있게 데이터를 전송할 수 있는 방법을 제안한다. 제안하는 방법은 송,수신하는 두 노드의 전송범위에 공통으로 속한 노드들이 전송되는 데이터를 중복 전송하게 된다. 그리하여 링크의 단절이 일어날 경우 발생하는 경로 재 탐색 및 경로복구의 발생 빈도를 줄이고 동시에 데이터 전송률을 증가시켜 신뢰적인 데이터 전송을 하게 된다.

In assessing energy performance, the important issue is how architects and HVAC engineers cope with uncertainties in building. In order to treat the uncertainty in energy performance assessment in conceptual design stage, the authors selected uncertain parameters. To conduct uncertainty analysis, the Latin Hypercube Sampling(LHS), one of the Monte-Carlo methods was employed. For this study, one library building of three design alternatives in the conceptual stage was selected. As a sumulation tool, EnergyPlus developed by DOE(US federal Department Of Energy) is utilitzed. In the paper, the impact of uncertainty on energy performance assessment in conceptual design stage is highlighted.

This study aims to develop a gamification-based English reading learning application and teaching model for Korean middle school EFL learners to improve their English reading comprehension, motivation, and self-efficacy. This application was designed based on eight elements of game design (points, levels, badges, leaderboards, rewards, progress bars, storylines, and feedback). Each game design element is utilized to (a) improve EFL learners’ motivation and self-efficacy in English reading and (b) promote the use of English reading strategies. The English reading strategies are provided differently according to pre-, while-, and post-reading stages to improve EFL learners’ English reading comprehension. Moreover, this study also suggests how to use this newly developed application effectively in an English reading classroom. This study is meaningful in that it systematically not only presents an innovative method for Korean EFL learners’ English reading comprehension, motivation, and self-efficacy but also proposes an English reading teaching model with each English reading strategy through gamification in the field of English teaching and learning. In particular, a gamification-based English reading learning application allows Korean middle school EFL learners to be engaged and motivated in English reading. More detailed discussions and suggestions are given for English teachers and further potential research directions.

Objectives The purpose of this research was to examine differences between clinical variables among outpatients with schizophrenia in competitive and partial employed and unemployed groups. Methods The study subjects were 168 outpatients with schizophrenia, and these were divided into three groups, that is, competitive (n=20), partial (n=28), and unemployed (n=120) groups, based on employment status. Job and psychopathology data were collected by interview and using self-report questionnaires (self-stigma, will to recover, family attitude, perceived social support, insight into disease, self-esteem, hopelessness, and attitude to drugs). Results The proportion of male patients in the competitive employment group was greater than in the partial or unemployed groups. Education level was significantly higher, and the number of hospitalizations was significantly lower in the competitive group than in the unemployed group. Levels of self-stigma, will to recover, and perceived social support were significantly higher, and levels of self-esteem and hopelessness were significantly lower in the competitive and partial employment groups than in the unemployed group. Patients in these two groups also reported a more positive family attitude, more insight into the disease, and a more positive attitude toward drugs than patients in the unemployed group. Conclusion Most clinical variables were similar in the competitive and partial employment groups. The findings of this study suggest environmental and systematic factors are more important for the employment of outpatients with schizophrenia than disease-associated factors.

Recently, great attention has been shown to the question of condensation risk of multi-residential houses. Ministry of Land, Infrastructure and Transport recently announced the standard for preventing the condensation of wall, window system, door in multi-residential houses in Korea. The purpose of this study is to proceed with the condensation risk of the window system performance evaluation based on mentioned standard of Korea. For this study was to perform the simulation and applied to the actual selection of window-system multi-residential houses and change variables. Variable is Low-e coating and cavity-space(total 6-alteration). One of the method that estimates the Temperature Difference Ratio(TDR). Partially, this paper presents a study to investigate the difference between the KS F 2295 and the mentioned standard. The results indicate that both of two methods deliver meaningful information to DM (Desicion Maker). In the paper, pros andcons of two methods are discussed. As a simulation tool, Physibel-Trisco by Physibel in belgium. Consequently, this study is to examine evaluation of inside suface condensation risk in window system throught Low-e coating and type of cavity space.

본 연구는 사회복지시설 민간위탁과 관련하여 최근 학계와 현장에서 활발한 논의가 지속적으로 이루어지고 있는 시점에서 서울특별시 자치구의 사회복지시설 민간위탁에 관한 자치법규를 비교 · 분석하여 향후 타기초자치단체에 제 · 개정될 자치법규의 발전적 방안을 모색하고자 하였다. 분석자료는 2015년 5월 1일을 기준으로 자치법규정보시스템을 활용하여 서울특별시 자치구에서 제정한 자치법규를 수집하였으며, 최항순(2003)이 제시한 민간위탁 단계에 따라 조항의 존재여부와 내용구성 등에 관하여 분석하였다. 분석 결과를 토대로, 첫째, 수탁자 모집단계에서 모집공고나 적용시설 유형의 명확성, 위탁기간의 이원화, 둘째, 수탁자 선정단계에서 수탁자 선정기준과 위원회의 위원장 선출방식의 개선, 셋째, 행정기관의 관리감독에 관한 조항, 넷째, 재위탁 단계에서 위탁사무에 관한 평가와 심의에 관한 조항의 전반적 보완과 더불어 투명한 평가가 이루어질 수 있는 제도적 장치가 마련되어야 함을 제안하였다. In this study, as recently there is active discussion in academia and relevant industries relating to delegation of social welfare facilities to the private sector, self-regulations relating to such delegation by Seoul was analyzed for systematic supply of social welfare service and find ways to improve self-regulations that will be enacted or amended by local governments. The data was collected from self-regulations of Seoul based on the self-regulation information system as of May 1, 2015, and analyzed according to the steps of delegation to the private sector proposed by Hyangsun Choi, in terms of presence of clauses and contents. Based on the analysis, the study prosed: first, clarity in description of application criteria and relevant facilities and dual system of the delegation agencies; second, improvement in criteria for selecting the delegation agencies and the head of committee; third, clauses related to supervision of an administrative agency; fourth, overall improvement of clauses related to evaluation nd review of delegation and institutional arrangement for more transparent evaluation.
