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.

This study was performed to identify factors affecting the profitability of private hospitals in Korea different and to make informations that could be very helpful to hospitals in improving profitability. Data used in this study were collected from 112 hospitals with complete general data of present conditions as well as financial statements(balance sheets, income statements). They were chosen from hospitals that passed the standardization audit undertaken by the Korean Hospital Association from 1998 to 2001 for the purpose of accrediting training hospitals. The dependent variables were used operating margin to total assets and operating margin to gross revenues as proxy indicators for profitability. The independent variables were ownership type, location, bed size, period of establishment, debt to total assets, current ratio, fixed ratio, total asset turnover, average length of stay, bed occupancy rate, admission ratio of outpatients, personnel costs per adjusted inpatient, and fiscal years. The factors had significantly positive effect on operating margin to total assets and operating margin to gross revenues were bed size, total asset turnover. And the factors had significantly negative effect on operating margin to total assets and operating margin to gross revenues were period of establishment, debt to total assets, average length of stay, personnel costs per adjusted inpatient. The adjusted $R^2$ of multiple regression equation was 25.2%, 21.4% respectively. It is very important for private hospitals to improve profitability by raising total asset turnover, and reducing debt to total assets, average length of stay, and personnel costs per adjusted inpatient using the rational and efficient business strategy.

Objectives : This article aims to give guidance on the conduct and reporting of case series and audits of acupuncture, based on common problems that have arisen in the past. This type of project, and particularly the prospective case series or pre- post-intervention study, may give valuable evidence of the overall effectiveness of acupuncture-for example in different situations and in different conditions- and provides one step in the research pathway before generating an hypothesis. Results & Discussion : The project should be designed with the aim of reducing bias as much as possible. Careful and detailed planning is essential for the project to produce worthwhile results that readers can evaluate and replicate. Ethical issues should be considered and formal approval may be necessary. The patient group should be recruited systematically and baseline data obtained. The treatment given should be systematic and decisions to change or end treatment made explicit. The outcome should be measured in ways that are known to be reliable and valid. Musculoskeletal problems can be evaluated with scales for pain and confirmed by measuring one other symptom such as stiffness or one other aspect such as bothersomeness. Global change scores also provide supporting information, and the MYMOP (Measure Yourself Medical Outcome Profile) measure is popular when patients with different conditions are included. The design of questionnaires for beliefs and attitudes is a specialised area that should not be attempted without expert help. Adverse events should also be recorded. Analysis of the data and the best way of summarising and presenting the results are also discussed.

Purpose: This study was done to identify the influence of severity of drinking problem, circadian rhythm and sleep quality in patients with alcohol use. Methods: A descriptive study design was utilized. Data were collected using self-report questionnaires from 139 patients with alcohol use disorder who were admitted to a psychiatric hospital in D city, Korea. The questionnaires included Alcohol Use Disorders Identification Test (AUDIT), Composite Scale of Morningness (CMS), Pittsburgh Sleep Quality Index (PSQI), and Korea sleep scale A. Data were analyzed using descriptive statistics, Pearson's correlation coefficients, and multiple regressions using the SPSS 20.0 program. Results: There was significant correlations among severity of problem drinking, circadian rhythm, sleep quality and sleep disorder. The significant factors influencing sleep disorder were severity of problem drinking(${\beta}=.12$, p= .042), circadian rhythm(${\beta}=-.14$, p= .039) and sleep quality(${\beta}=.63$, p= < .001). This model explained 56% of variance in sleep disorder(F = 57.34, p= < .001). Conclusion: The results of this study suggest that the development of sleep intervention programs for alcohol use disorder patients needs to consider severity of alcohol use, circadian rhythm and sleep quality, and sleep assessment and intervention are needed the early stage of the treatment and recovery process.

Purpose: The study aimed to determine the impact of post-traumatic stress and ways of stress coping on problem drinking in firefighters. Methods: Data were collected from May 11 to June 11, 2015, in fire brigades across South Korea. Participants were 183 male firefighters who used self-report questionnaires containing questions from the Impact of Event Scale-Revised (IES-R), Ways of Coping Checklist (WCC), and Alcohol Use Disorders Identification Test (AUDIT). Data were analyzed using $x^2$ test, t-test, and logistic regression with the SPSS/WIN 21.0 program. Results: The prevalence of PTSD among firefighters was 36.7% and that of problem drinking was 39.3%. Firefighters with single (OR=0.23, 95% CI=0.038~1.321) and married status (OR=0.46, 95% CI=0.069~3.040) were less likely to have problem drinking than those who were divorced or bereavement. Those with invasion symptoms (OR=1.17, 95% CI=1.031~1.327) and hyperarousal symptoms (OR=0.85, 95% CI=0.722~0.989) were more likely to have problem drinking than those with avoidance symptoms. Conclusion: Post-traumatic stress symptom was a major risk factor that increased problem drinking, and married status reduced problem drinking. There is a need to develop post-traumatic stress symptom management program and early education content for symptom management.

파일 무결성 검사는 시스템 자원의 안정성 여부를 판단할 수 있는 가장 확실한 방법이지만, 관리자의 경험과 능력에 따라 검사 시간과 효과에 많은 차이가 있을 수 있다. 따라서 가능한 빠른 대웅을 필요로 하는 침입 복구 및 대웅 시스템에 바로 사용하기에는 적합하지 않으며, 또한 손상 자원의 복구에 필요한 자원의 상태 정보는 수집 가능하지만 침입을 차단하기 위해 필요한 침입 행위 주체에 대한 정보는 수집할 수 없다. 본 논문에서는 위의 두 가지 문제를 해결하기 위해 시스템 호출 감시와 파일 무결성 검사를 연동하여 실시간으로 파일의 무결성을 검사하는 rtIntegrit을 제안한다. rtIntegrit은 Syswatcher라는 시스템 호출 검사 도구를 사용하여 요청된 행위를 항상 감시한다. 만약 지정된 파일에 이상 동작이 나타나면 이의 변화에 대하여 실시간으로 무결성 검사를 수행하도록 하고, 해당 관련된 프로세스의 정보를 수집하고 보고함으로서 침입 차단에 활용하게 한다. 또한 IDMEF 형식의 표준으로 감사 자료를 생성하여, 침입 대웅 및 복구 시스템들과 쉽게 연계할 수 있다.

시스템 호출 감사자료기반 기계학습기법을 사용한 프로그램 행위 학습방법은 효과적인 호스트 기반 침입탐지 방법이며, 규칙 학습, 신경망, 통계적 방법, 은닉 마크로프 모델 등의 방법이 대표적이다. 그 중에서 신경망은 시스템 호출 시퀀스를 학습하는데 있어 적합하다고 알려져 있는데, 실제 문제에 적용하여 좋은 성능을 내기 위해서는 그 구조를 결정하는 것이 중요하다 하지만 보통의 신경망은 그 구조를 찾기 위한 방법이 알려져 있지 않아 침입탐지에 효과적인 구조를 찾기 위해서는 많은 시간이 요구된다. 본 논문에서는 기존 신경망 기반 침입탐지시스템의 단점을 보완하고 성능을 향상시키기 위해 진화신경망을 이용한 방법을 제안한다. 진화 신경망은 신경망의 구조와 가중치를 동시에 학습하기 때문에 일반 신경망보다 빠른 시간에 더 좋은 성능의 신경망을 얻을 수 있다는 장점이 있다. 1999년의 DARPA IDEVAL 자료로 실험한 결과 기존의 연구보다 좋은 탐지율을 보여 진화신경망이 침입탐지에 효과적임을 확인할 수 있었다.
