The construction waste concrete produce from the demolished concrete structures. These waste concrete materials are useful and valuable for fill and subgrade and are considered to use as the subgrade material of the road. To use the subgrade of the road with the waste concrete, the several experiments involved with compaction test and laboratory C. B. R. etc. are performed. These experiments are compared with criteria of the road construction manual. It is shown that the quality of the construction waste concrete satisfies that of the subgrade mentioned in the road construction manual.

Purpose: The purpose of this study was to develop and validate health care providers' counseling manual in mobile application for lifelong health care among patients with chronic hepatitis B. Methods: The mobile application was developed using a prototyping approach and system developing life cycle method, evaluated by users for their satisfaction with the counseling manual and experts for the quality of the manual. To evaluate application of the counseling manual, knowledge and counselor self-efficacy of the subjects were measured and compared before and after application of the counseling manual. Results: There were statistically significant increases in knowledge and counselor self-efficacy in the user group. A mobile application with high accessibility and applicability including information and counseling factors can promote counseling competence of the nurse as health care provider caring chronic hepatitis B patients. Conclusion: The results of this study indicate that the counseling manual in mobile application is effective in increasing knowledge and counselor self-efficacy among nurses to promote lifelong health care among patients with chronic hepatitis B. Therefore, it can be usefully utilized in the field of nursing for patients with chronic hepatitis B as a nursing intervention.

Objectives : The purpose of this study was to review the effectiveness of Chuna manual therapy for the treatment of tension type headache(TTH). Methods : All processes were independently carried out by three investigators. Literature search was performed in 3 databases(pubmed, OASIS, NDSL) from their inception to May 2016. Searched reports was twice excluded for title, abstract and body. And then, data extract and analysis was done before assessing risk of bias by Cochrane Handbook. Results : 11 RCT were included. Generally, Fascia Chuna therapy and Chuna spine & joint manipulation therapy were used for TTH. Except for 1 report, Chuna manual therapy was shown to be effective in treating TTH. In assessing risk of bias, because of the characteristic of intervention, blinding of participants was high risk of bias in most reports. Conclusions : Chuna manual therapy was shown to be effective in treating TTH. In korea, better designed trials with high quality is needed from now on.

Objectives This study is to investigate domestic trends of chuna manual therapy on traffic accident for recent 10 years. Methods We searched the studies on chuna manual therapy for traffic accident in 6 Korean web databases. Consequently, 17 research papers were founded. We analyzed these papers according to their published year, the titles of journal, the type of study, the number of cases, the sites of injury, assessment scales of study, and ethics of research. Results 17 papers were published since 2005. The studies on chuna manual therapy about traffic accident were mainly published in the journal of korean society of chuna manual medicine for spine & nerves and the journal of korean medicine rehabilitation. All papers were clinical research include 2 case series, 2 non randomized controlled trials (NRCTs), 13 randomized controlled trials (RCTs). The most frequently occured symptom was neck pain. In assessment scales, visual analog scale (VAS) was mainly used. All clinical studies were not mentioned about approval of institutional review board (IRB). Conclusions In this study, we analyzed the trends of chuna manual therapy on traffic accident in Korea from 2005 to 2014. In reviewing published papers, we found several weak points in methods of research and quality of study protocol. It is needed to adjust these problems for development of future researches.

Objectives This study aims to analyze the effectiveness of manual therapy for the treatment of plantar fasciitis by reviewing existing randomized controlled trials. Specifically, it seeks to identify various manual therapy techniques and evaluate their applicability in clinical settings. Methods The study reviewed literature from six databases (PubMed, the Cochrane Library, China National Knowledge Infrastructure, ScienceON, Research Information Sharing Service, Korean studies Information Service System) up to April 2024. Studies were selected based on criteria including randomized controlled trials involving manual therapy for plantar fasciitis. Results An analysis of ten studies involving 714 patients revealed the use of techniques such as joint mobilization, muscle relaxation, and pressure point techniques. Manual therapy was found to be more effective in reducing pain than both extracorporeal shock wave therapy and routine physical therapy alone. However, caution is needed in generalizing these results due to the limited number of studies analyzed. No significant adverse effects were reported. Conclusions Manual therapy demonstrates potential as an effective treatment for plantar fasciitis, offering benefits in pain management and functional recovery. However, further high-quality randomized controlled trials are necessary to strengthen the clinical evidence and establish standardized treatment protocols.

국방부 또는 공공기관에서 관리하는 모든 데이터베이스 및 시스템의 데이터는 일정 품질 이상 보장하는 것이 원칙이나 대부분 다수의 정보시스템을 구축·운영하기 때문에 현실적으로 모든 시스템에 대한 데이터 품질관리는 한계가 있다. 국방데이터는 업무의 특성상 공개되지 않는 데이터가 대부분이고 군에서 업무의 필요 및 중요도에 따라 전략적으로 개발되거나 통합되어 관리하는 시스템이 많다. 또한, 무기체계에서 발생하는 센서데이터, 비정형데이터, 인공지능 학습데이터 등 데이터 품질관리가 필요한 다양한 유형의 많은 데이터가 축척되고 생성되고 있다. 그러나, 국방데이터를 위한 데이터 품질관리 가이드 및 품질관리 대상 선정에 대한 가이드가 부재한 상황이고, 공공데이터 품질관리 매뉴얼의 기준에 따라 국방데이터의 품질관리 대상 데이터베이스 및 시스템을 선정하기에는 선정 기준이 모호하며 실무 담당자에 의존적이다. 따라서, 본 논문에서는 국방데이터의 품질관리를 위한 대상 체계 선정 기준에 대하여 제안하며, 제안한 선정기준들과 기존 매뉴얼의 선정기준과의 관계성에 대하여 기술한다.

Optimization of design is an important step in obtaining tissue engineering scaffolds with appropriate shapes and inner micro-structures. Different shapes and sizes of scaffolds are modeled using UGS NX 6.0 software with variable pore sizes. The quality issue we are concerned is the scaffold porosity, which is mainly caused by the fabrication inaccuracies. Bone scaffolds are usually characterized using a scanning electron microscope, but this study presents a new automated inspection and classification technique. Due to many numbers and size variations for the pores, the manual inspection of the fabricated scaffolds tends to be error-prone and costly. Manual inspection also raises the chance of contamination. Thus, non-contact, precise inspection is preferred. In this study, the critical dimensions are automatically measured by the vision camera. The measured data are analyzed to classify the quality characteristics. The automated inspection and classification techniques developed in this study are expected to improve the quality of the fabricated scaffolds and reduce the overall cost of manufacturing.

디지털 유방촬영술은 유방의 두께 및 유선조직의 밀도에 따라 노출조건이 자동으로 이루어지는 자동노출제어장치를 사용하고 있는데 이는 피폭선량을 증가시키는 원인이 되기도 한다. 이 연구에서는 디지털 유방확대촬영술에서 영상의 질을 유지하며 불필요한 방사선 피폭을 줄이기 위한 최적의 방사선량 촬영조건을 알아보았다. 자동노출방식을 사용할 경우 가장 좋은 영상화질을 얻을 수 있었으나 평균유선선량 역시 가장 높았다. 수동노출방식의 경우 자동노출방식의 55 % 정도의 mAs 값만으로도 기준 팬텀영상 점수와 신호대잡음비를 얻을 수 있으며 평균유선선량은 55 % 이하로 줄일 수 있었다. 위와 같은 결과를 참고로 하면 디지털 유방확대촬영 시 자동노출방식보다는 수동노출방식을 이용함으로써 불필요한 환자의 피폭선량을 줄일 수 있을 것이라 생각된다.

DUPIC powder and pellets were successfully fabricated in accordance with the quality assurance program described in the Quality Assurance Manual for DUPIC fuel fabrication, which was developed on the basis of the CAN3-Z299.2-85 standard. This manual describes the quality management system applicable to the activities performed for DUPIC fuel fabrication. It covers the work processes, policies and procedures used for planning, executing, and verifying the work carried out for DUPIC fuel fabrication. It is important that a Quality Program is in place before the fabrication of the fuel for irradiation testing. In order to qualify the DUPIC pellet manufacturing processes, 3 series of experiments for the pre-qualification and 3 series for the qualification were performed. In these experiments, the optimum process conditions were established. Then, under the control of the QA program, 8 series of production runs were performed to make the qualified DUPIC pellets in a batch size of 1 kg. In these production runs, DUPIC fuel pellets satisfying the standard CANDU fuel pellet specifications could be successfully produced.
