한국은 성능기반항행 (PBN; performance-based navigation)으로 전환하기 위한 단계적 PBN 이행계획을 2010년에 수립하고 로드맵에 따른 새로운 비행절차를 개발 중에 있다. PBN 비행절차에는 GNSS (global navigation satellite systems), DME (distance measuring equipment), VOR (VHF omnidirectional range), INS (inertial navigation system) 등의 항행시설 (NAVAID; navigation aid)이 활용되는 것으로 되어있다. 그 중에서 GNSS를 이용한 PBN 업무제공이 중심을 이루고 있는 실정이다. 그러나 위성항법신호의 인위적, 자연적 간섭에 의한 취약성이 발견됨에 따라 세계 각국은 다양한 대안항법(APNT; alternative positioning, navigation and timing) 기술을 연구하고 있다. 본 논문에서는 GNSS 신호가 가용하지 않을 경우 기존의 항행시스템으로 지속적인 PBN 운항이 가능한지를 분석하였으며, 결과적으로 국내 일부 공항은 접근 단계 구역에서 대안항법의 구축이 필요한 것으로 나타났다.

This study was conducted in order to evaluate the current status of management of students affected by food allergy and provide basic data necessary to school foodservice. A survey was conducted on 300 nutrition teachers (dietitians). For food allergy management, 79.3% of participants regularly checked on students with food allergy. The rate of providing allergy-free or alternative food for students with food allergy was 35.7%; and the reasons for not providing such food was 'lack of cooking time and employees' (69.4%). Furthermore, 79.7% of participants provided nutrition education and counseling for students with food allergy and the reasons for not providing education and counseling was 'lack of time' (59.0%). Nutrition teachers (dietitians) with experience of job training related to food allergy comprised 53.7%. The mean score of importance of food allergy management was 4.02/5.00. The items with high scores of importance of ${\geq}4.20/5.00points$ were periodical check on students with food allergy, sending newsletters or homepage posting of foods causing allergy; however, provision of allergy-free or alternative food scored 3.64/5.00 points. The score of importance was significantly higher in those who checked on students with food allergy (p<0.05), offered allergy-free or alternative food (p<0.01), and in those with experience of job training (p<0.05) than those who did not. Therefore, in order to manage students with food allergy, nutrition teachers (dietitians) require on-going training on food allergy in order to practice provision of alternative foods and administrative support to the cooking personnel and facilities.

In this study, 2 pure hydrocarbon refrigerants of R1270 (Propylene) and R290 (Propane) and 3 binary mixtures composed of R1270, R29O and R152a were tested in a refrigerating bench tester with a scroll compressor in an attempt to substitute R502 used in most of the low temperature applications. The test bench provided 3\sim3.5$ kW capacity and water and water/glycol mixture were employed as the secondary heat transfer fluids. All tests were conducted under the same external conditions resulting in the average saturation temperatures of -28 and $45^{\circ}C$ in the evaporator and condenser, respectively. Test results showed that all refrigerants tested had $9.6\sim18.7\%$ higher capacity and $17.1\sim27.3\%$ higher COP than R502. The compressor discharge temperature of R1270 was similar to that of R502 while those of all other refrigerants were $23.7\sim27.9\%$ lower than that of R502. For all alternative refrigerants, the amount of charge was reduced up to $60\%$ as compared to R502. Overall, these alternative refrigerants offer better system performance and reliability than R502 and can be used as long term substitutes for R502 due to their excellent environmental properties.

Objective : This review aims at analyzing Complementary and Alternative Medicine (CAM) therapies, using for oral health to know current use of CAM in dental area by analyzing randomized controlled clinical trials (RCTs). Method : We searched the following 6 electronic databases until 1 July 2014. : Pubmed, Medline, Embase, Allied and Complementary Medicine Database(AMED), Cumulative Index to Nursing and Allied Health Literature(CINAHL), the Cochrane Library. We included parallel RCTs and cross-over RCTs that assessed the efficacy of CAM regardless of blinding and language. Results : A total of 154 RCT articles were included. There were 2-arm parallel study design(69.5%), 3-arm parallel study design(20.8%), 4-arm parallel study design(4.5%) and Cross-over design(5.2%). Complementary and alternative medicine RCTs in oral health tend to increase in the early-2000s and in the mid-2010s. In addition, 154 citations were classified according to diseases and interventions that categorized Natural Products studies(68.2%), Mind and Body Practices studies(31.8%). We classified in detail that vitamin and mineral therapies(29.9%), dietary supplements(24.7%), acupuncture(23.3%), Herbal medicine(13.6%), homeopathy (2.6%), energy therapies(2.6%), Massage(1.9%), biofeedback(0.6%), traditional medicine(0.6%). Conclusion : Increasing publications and diverse interventions regarding CAM for oral health is observed by analyzing RCTs from the literature review. Further studies are needed to be performed as systematic reviews to verify their effectiveness and the research to inquire into side effect.

학교폭력 예방을 위한 정책대안을 찾으려는 노력이 큰 성과를 거두지 못하고 있는 것이 현실이다. 마침 부산지역에서 최초 시행하여 전국에 걸쳐 시범 실시되고 있는 스쿨폴리스(배움터지킴이)제도는 전직경찰과 전직교사가 협력하여 학교 폭력 예방을 위한 순찰과 상담 등의 활동을 전개하는 제도로서 관계기관이 유기적으로 협력하여 네트워크로서 활동한 초보적 사회안전망이라는 의미가 있지만 근본적인 학교폭력 문제의 해결을 위해서는 보완되어야 할 문제점도 가지고 있다. 이 논문은 배움터지킴이 제도의 문제점을 보완함으로써 가정과 학교, 경찰과 지역사회가 유기적으로 연계하여 학교폭력의 근본적 예방을 위해 협력하는 종합적 사회안전망의 모형을 구상하고자 하였다. 학교폭력의 예방은 학교만의 노력으로는 불가능하며 사회구성원 모두의 참여를 필요로 한다는 관점에서 구성원의 유기적 협조체제 구축은 중요한 일이라고 할 수 있다. 사회안전망의 기본적 얼개를 구상함에 있어서는 지역사회경찰활동과 적극적 경찰활동기법 그리고 환경설계를 적용한 방범활동기법의 이론을 배경으로 하였다. 또한 학교폭력예방 및 대책에 관한 법률의 기본골격과 조화를 맞추기 위해 학교폭력대책자치위원회의 기능을 확대하고, 117학교폭력긴급지원센터의 신고 및 상담접수기능과 연결하여 집행기능을 수행하는 학교폭력지원센터를 신설, 집행기구로서 핵심적 역할을 수행하는 것으로 구상하였다.

본 연구의 목적은 대안교육 분야 특성화고등학교에서 진행하고 있는 독서교육의 특성을 파악하는 것이다. 독서교육이 비교적 활발히 이루어지고 있는 대안교육 분야 특성화고등학교 5곳을 연구 대상으로 선정하였으며. 이들 학교들이 현재 진행하고 있는 독서교육의 내용 및 특성을 파악하기 위해 해당 학교의 독서교육 담당자와 심층인터뷰를 실시하였다. 인터뷰내용은 전사한 후 질적 분석방법으로 분석하였다. 분석결과 대안학교에서는 인문학을 바탕으로 교과수업과 독서교육을 통합하고자 노력하고 있었으며, 도서관 활용수업이 진행되고 있었고, 독서 프로그램 기획, 진행에 학생들이 적극적으로 참여하고 있었다. 또한 독서교육이 성공적으로 진행될 수 있었던 조건들도 드러났다. 우선 교사, 학교, 도서관이 독서교육을 지지하고 지원하는 체계를 갖추고 있었으며, 독서 프로그램에 학생들의 관심과 흥미가 적극적으로 반영되고 있었다. 이와 더불어, 학생들의 독서 능력과 필요에 따라 독서교육 내용이 차별화되어 구성되고 있었으며, 독서 후 대화하고 소통하는 활동이 강조되고 있었다.

In this letter, a heuristic channel allocation and scheduling scheme is proposed. By comparing the size of the alternative-factor assessment, which is obtained by simple calculation, we can easily find the most appropriate channel for each user for overall throughput enhancement. Numerical results show that the downlink throughput of the proposed scheme is higher than that of proportional fairness and is almost the same as that of the maximum C/I scheme, while user fairness remains better than that of the maximum C/I scheme.

Sho-Seiryu-To is known to be effective against allergic diseases, but its effect on skin itching has not been reported. We observed the effect of Sho-Seiryu-To on three elderly patients who, desoite using an anti-allergic drug, has severe chronic skin itching with peripheral eosinophilia. All three patients decreased their peripheral eosinophilia and improved their skin condition within eight weeks. We conclude that Sho-Seiryu-To could be capable of treating elderly patients with chronic skin itching and peripheral eosinophilia.

In this letter, we introduce confusion-based confidence measures for detecting an impostor in speaker recognition, which does not require an alternative hypothesis. Most traditional speaker verification methods are based on a hypothesis test, and their performance depends on the robustness of an alternative hypothesis. Compared with the conventional Gaussian mixture model-universal background model (GMM-UBM) scheme, our confusion-based measures show better performance in noise-corrupted speech. The additional computational requirements for our methods are negligible when used to detect or reject impostors.
