본 연구에서는 국토해양부와 통계청에서 제공하는 '도로교량 및 터널 현황' 통계자료를 이용하여 상부구조 형식, 경간장 등을 주요변수로 국내 프리스트레스트 콘크리트 교량의 현황조사 및 비교, 분석을 수행하였다. 경간장 50~100m인 경우 약 76% 이상이 강박스거더교로서 프리스트레스트 콘크리트 교량은 상대적으로 작은 비율을 나타내었다. 따라서 경간장 50~100m에 강박스거더교를 대체하여 적용할 수 있는 고강도 강선 및 고강도 콘크리트를 적용한 프리스트레스트 콘크리트 교량의 개발과 적용이 필요하며, 이를 통해 보다 경제적인 교량 설계 및 시공이 가능할 것으로 판단된다.

본 연구는 학교도서관 전담인력의 전문성 강화를 위한 계속교육에 대한 현황과 실태를 조사하고 계속교육의 개선방안을 제시하는 것을 목적으로 한다. 이를 위하여 경기도 고양지역 초 중 고등학교도서관에 근무하는 사서교사 및 사서 69명을 대상으로 설문조사를 실시하고 빈도분석 및 교차분석을 실시하였다. 연구결과는 다음과 같다. 첫째, 사서교사의 계속교육에 대한 관심과 참여 경험이 높다는 사실을 파악하였다. 둘째, 참여비중이 가장 높은 계속교육 유형은 단기연수 및 강습과정으로 나타났으며, 제공되고 있는 계속교육이 실무와의 연계성이 낮은 것으로 나타났다. 셋째, 관리자의 낮은 인식과 지역적 제약과 적합한 계속교육 프로그램의 부재가 계속교육의 방해요인으로 나타났다. 넷째, 근무시간 중과 방학 중의 계속교육을 선호하며, 다양한 주제의 계속교육 필요성이 강조되었다. 이를 통해 지속적이고 장기적인 계속교육, 계속교육을 독려하기 위한 정책지원, 전문성을 위한 계속교육 과정 개발, 관리자의 인식전환 및 계속교육에 대한 홍보가 필요함을 제안하였다.

Purpose: This study was a systematic review and meta-analysis to explore the factors related to quality of life in heart transplant recipients. Methods: To identify studies that suggested the factors related to the quality of life in heart transplant recipients, we searched the articles published from 1974 to November 2018 using Six databases, PubMed, CINAHL, EMBASE, Cochrane, KMBASE and RISS. A total of 22 studies were selected out of 5,234 for the systematic review and meta-analysis on the basis of the PRISMA flow. The quality of study was assessed by assessment tool form the NIH and meta-analysis was performed using the 'R 3.5.2' version to analyze the correlated effect sizes. Results: Factors related to quality of life in heart transplant recipients were categorized into six domains based on the health-related quality of life model introduced by Ferrans: individual, environmental, biological function, symptoms, functional status, and general health perception. In the meta-analysis, 34 factors were used and 17 factors having significant effect sizes were as follows: self-efficacy, demoralization, perceived control, current occupational status, age, marital status, health promotion life style in the individual characteristics; stress in environmental characteristics; physical function status, creatinine level, left ventricular ejection fraction (LVEF) in biological function; anxiety, depression, symptom frequency and distress in symptoms domain; coping, self-care compliance in functional status. Conclusion: The findings indicate that the multi-dimensional factors influencing the quality of life in heart transplant recipients and provide the evidence for developing effective interventions for improving the quality of life of recipients.

This article aims to develop an algorithm that detects fire pump defects by analyzing the current signals of an induction motor, which are triggered by changes in the flow rate and pressure of multistage volute pumps that are used for fire services. The operational status of the pumps was categorized into three: first, normal operation; second, a defect that is caused by a change in the current value; and third, a defect occasioned by a change in current, pressure, and flow rate. When a fire pump was in normal operation, the motor's operating current was measured between 5.06 A and 6.9 A, the flow rate was estimated at 0-0.27 m³/min, and the pressure ranged from 0 to 0.47 MPa. In the event that a defect was caused by an abnormal current value in the motor, it was attributed to the pump's adherence. Furthermore, if there was no source of water, the defect was considered to have been induced by phase-loss operation, no-load operation, or run-stop operation, with the current value of each scenario being measured at > 52.8 A, < 4.13 A, > 45.15 A, and < 3.8 A, respectively, placing its overall range between 0 and 50 A. The sources of defects were detected based on an analysis of the flow rate, pressure, and current, which represent the following causes: air inflow into the casing, inadequate suction of water, and reverse-phase operation, respectively. Each cause entailed the following values: when air seeped into the casing, the pressure was measured at 0.24 MPa irrespective of changes in the flow rate; when there was inadequate suction of water, the pressure was recorded between 0 and 0.05 MPa despite changes in the flow rate; and when the power line's reverse-phase loss was the cause of the defect, the pressure was measured at 0.33 MPa for a flow rate of 0 L/min, and a higher flow rate decreased the pressure to nearly 0 MPa. The results of this study will enable engineers to develop a pump defect detection algorithm that is based on an analysis of current, and this algorithm will facilitate the execution of a program that will control a fire pump defect detection system.

Objectives : In this report, we were studied the current status and future about cultivation of medicinal plants in Japan. Methods : To analysis the management and production of medicinal crops in Japan, variation of importation and cultivation of four medicinal crops such as Angelica acutiloba Kitagawa, Cnidium officinale Makino, Paeonia lactiflora Pallas and Rehmannia glutinosa Liboschitz var. purpurea Makino within 22 years ($1981{\sim}2002$) were investigated. Also we analyzed the herbal drug market in Japan using literature. Results : In the results, cultivated area and amount of Angelica acutiloba Kitagawa and Paeonia lactiflora Pallas reduced more than 50% within 22 years ($1981{\sim}2002$). Production decrease of medicinal crops is alloting through contract production in China. The cultivation of Rehmannia glutinosa Liboschitz var. purpurea Makino is enforcing minimum procluction for seed security.
