Objectives: This study aimed to investigate the experiences and awareness of Korean Medicine professors towards research ethics issues and curriculum development. Methods: Electronic mails for requesting the survey participation were sent to 531 professors who were listed in the DB of Association of Korean Medicine. Professors who agreed to participate in the survey were connected to the self-administered questionnaire site, and the responses were stored in real time. Professors were asked the experience of research misconduct cases, the necessity, contents and evaluation method of research ethics education, etc. ANOVA was performed to test the differences of ethics education effects among sub-groups of respondents. Results: Of 137 professors who opened the e-mail, 127 completed the questionnaire. Most professors (87.4%) reported to witness the research misconduct cases, and felt the necessity of research ethics education for professors as well as students. 31.4% of respondents preferred the practice-focused course, and 43.3% preferred the PASS/FAIL basis evaluation system. Professors with shorter education career and professors majoring basic Korean Medicine expected higher effect of ethics education than others. For detailed items of research ethics education, 'ethical writing' and 'ensuring research integrity' were prioritized in the aspects of both personal ethics and social demand. Conclusions: In this study, detailed matters of research ethics education in Korean Medicine area were drawn. Further study and policy development are needed to facilitate the introduction of formal education of research ethics.

In various sensor network applications, such as climate observation organizations, sensor nodes need to collect information from time to time and pass it on to the recipient of information through multiple bounces. According to field tests, this information corresponds to most of the energy use of the sensor hub. Decreasing the measurement of information transmission in sensor networks becomes an important issue.Compression sensing (CS) can reduce the amount of information delivered to the network and reduce traffic load. However, the total number of classification of information delivered using pure CS is still enormous. The hybrid technique for utilizing CS was proposed to diminish the quantity of transmissions in sensor networks.Further the energy productivity is a test task for the sensor nodes. However, in previous studies, a clustering approach using hybrid CS for a sensor network and an explanatory model was used to investigate the relationship between beam size and number of transmissions of hybrid CS technology. It uses efficient data integration techniques for large networks, but leads to clone attacks or attacks. Here, a new algorithm called SBEA (Snowball Endurance Algorithm) was proposed and tested with a bow. Thus, you can extend the battery life of your WSN by running effective copy detection. Often, multiple nodes, called observers, are selected to verify the reliability of the nodes within the network. Personal data from the source centre (e.g. personality and geographical data) is provided to the observer at the optional witness stage. The trust and reputation system is used to find the reliability of data aggregation across the cluster head and cluster nodes. It is also possible to obtain a mechanism to perform sleep and standby procedures to improve the life of the sensor node. The sniffers have been implemented to monitor the energy of the sensor nodes periodically in the sink. The proposed algorithm SBEA (Snowball Endurance Algorithm) is a combination of ERCD protocol and a combined mobility and routing algorithm that can identify the cluster head and adjacent cluster head nodes.This algorithm is used to yield the network life time and the performance of the sensor nodes can be increased.

본 논문에서는 고감도 보급형 핵종 분석 모듈 개발을 제안한다. 제안하는 측정센서 모듈은 핵종 분석 분해능을 위한 전자부 구동회로, 핵종 분석 기능이 적용된 시제품 제작, 시제품에 적용되는 GUI 개발 등으로 구성된다. 핵종 분석 분해능을 위한 전자부 구동회로는 전자부 구동 회로 블록도에 의한 핵종 분석 분해능 과정, 방사선 측정에 사용되는 MCU 회로 설계, Spectrum 취득용 PC 프로그램 설계 등으로 나뉘어진다. 핵종 분석 기능이 적용된 시제품 제작은 128×128 픽셀의 OLED display, 조작을 위한 3개의 버튼, Li-ion 배터리, 배터리 충전을 위한 USB-C Type 포트의 구성을 추가하여 제작한다. 시제품에 적용되는 GUI 개발부는 현재시간, 측정 경과 시간, 토탈 카운트, 핵종 Spectrum 등의 화면구성으로 개발한다. 제안된 측정센서 모듈의 성능을 평가하기 위하여 공인기관 전문가 입회시험을 시행한 결과, 핵종 분석 장치에 Cs-137 표준선원을 이용하여 취득한 Spectrum(FWHM@662keV)으로 분해능 공식을 적용하여 계산한 결과가 17.77%의 분해능을 가짐이 확인되었다. 따라서, 제안된 본 논문에서 제안한 핵종 분석 분해능 방법이 기존의 상용의 핵종 분석 모듈보다 저렴하면서도 향상된 성능이 산출됨이 확인되었다.

Purpose: To validate the effectiveness of obtaining consent education on errors in the consent process and to develop the education program for researchers. Methods: From February 2019 to February 2022, a 30-minute, 1:1 face-to-face consent education developed using the ADDIE model was conducted on 78 nurses as principal investigators. An informed consent audit tool, which includes 6 items developed by Asan Medical Center Human Research Protection Center, was used to analyze errors in obtaining informed consent process. Data analysis was performed using the SPSS ver. 25.0, and the Mann-Whitney U-test and χ²-test were utilized to verify the difference in errors between the experimental and control groups. Results: The participants consisted of 42 in the experimental group and 36 in the control group, with no statistically significant difference between the 2 groups. Both 2 groups showed the highest frequency of documentation errors, followed by format errors, errors related to a suitability of investigator, participant, or participant's legally acceptable representative, witness and confidentiality issues. After education, there was a significant decrease in both format errors (p=0.002) and documentation errors (p<0.001) in the experimental group. The proportion of participants without any errors in all items was higher in the experimental group (35.7%) compared to the control group (5.6%), and this difference was statistically significant (p=0.001). Conclusion: The obtaining consent education program was found to be effective in reducing informed consent errors. This study emphasizes the importance of education, suggesting the need for its expansion and accessibility, as well as the necessity for all researchers conducting clinical studies to receive the obtaining consent education.
