  • Purpose: This study aimed to analyze the knowledge levels, attitudes, and factors affecting the choices on the education of the participants who completed their education of persons conducting clinical trial workers, and to assess the problems of the current education system for clinical trial workers, leading to improvements. Methods: Clinical trial workers (including principal investigators/subinvestigators, members of the Institutional Review Board [IRB], clinical research coordinators) who were affiliated to one of the 4 university hospitals running their own clinical trial center and IRB in Daegu and completed their education of persons conducting clinical trial workers were the subjects of this study. One hundred seven online questionnaires were answered from 2021-04-02 to 2021-04-17. Descriptive statistics and Pearson correlation analysis were used to analyze the acquired data. Independent t-test and 1-way analysis of variance were used to analyze the differences in the knowledge levels and attitudes following the characteristics of the education participants. Results: The baseline characteristics of the 107 participants were as follows: the majority of the participants were female (72.0%), were in their 30s (36.4%), had a nursing major (29.0%), were clinical research coordinators (63.6%), had never experienced a principal investigator (79.4%), had participated 3 or more educations (58.9%), had completed their maintenance course (55.1%), had 5 or more years of clinical trial experiences (34.6%). The fields on which participants had low levels of objective knowledge were "types and preparations on audits of clinical trials," "regulations on clinical trials (Pharmaceutical Affairs Act, Korea Good Clinical Practice)." The difficulties that the participants faced were on "annual educations" and "lack of information regarding the educations." Factors that showed significant differences in objective knowledge were sex (p=0.02), number of educations (p=0.004), the curriculum of 2020 (p=0.001). Age (p=0.004), having experienced a principal investigator (p=0.006), number of educations (p<0.001), the curriculum of 2020 (p<0.001), clinical trial career (p=0.001) were factors that significantly affected subjective knowledge. Attitudes toward the education were positively correlated with objective knowledge (r=0.20, p=0.04) and subjective knowledge (r=0.32, p=0.001). Major sources through which information on educations was acquired were "institutional notices," and major factors affecting the choices on the education were "when the education took place" and "where the education took place." "Within the affiliated institution," "Online classes (recorded)" and "IRB and review processes" were each the most preferred place, mode, and content of the education. Conclusion: Knowledge levels varied largely among participants who completed their education of persons conducting clinical trial workers, depending on their characteristics such as the number of educations. Participants also complained about their lack of information on educations. The quality of education may be improved if clinical trial organizations are designated as education facilities. Education programs must be developed considering the knowledge level and demand of the participants. Furthermore, as offline classes may be impossible due to pandemics such as the coronavirus disease 2019, the development of diverse and sophisticated online classes is looked forward to.

  • This paper presents an application of intelligent modeling method to manual control system with human operator. Human operator as a part of controller is difficult to be modeled because of changes in individual characteristics and operation environment. So in these situation, a fuzzy model developed relying on the expert's experiences or trial and error may not be acceptable. To supplement the fuzzy model block, a neural network based modeling error compensator is incorporated. The feasibility of the present fuzzy-neural modeling scheme has been investigated for the real human based target tracking system.

  • Glimepiride, a third generation sulfonylurea, is an antihyperglycemic agent widely used to treat type 2 diabetes mellitus. In this study, an untargeted urinary metabolomic analysis was performed to identify endogenous metabolites affected by glimepiride administration. Urine samples of twelve healthy male volunteers were collected before and after administration of 2 mg glimepiride. These samples were analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS), and then subjected to multivariate data analysis including principal component analysis and orthogonal partial least squares discriminant analysis. Through this metabolomic profiling, we identified several endogenous metabolites such as adenosine 3', 5'-cyclic monophosphate (cAMP), quercetin, tyramine, and urocanic acid, which exhibit significant metabolomic changes between pre- and posturine samples. Among these, cAMP, which is known to be related to insulin secretion, was the most significantly altered metabolite following glimepiride administration. In addition, the pathway analysis showed that purine, tyrosine, and histidine metabolism was affected by pharmacological responses to glimepiride. Together, the results suggest that the pharmacometabolomic approach, based on LC-MS/MS, is useful in understanding the alterations in biochemical pathways associated with glimepiride action.

  • The characteristics of the demographics in Korea as it gets older are the increase of Elderly Women and continuous progress in urbanization. In this study, body shapes are classified as standard, obese, and tiny according to the previous studies based on the body shape characteristics and the body measurement of the Elderly Women. Based on the classification, we developed prototype of the panty for the Elderly Women to provide basic materials for the quality enhancement of the clothing of the increasing Elderly Women. The followings are the result of the study. 1. To categorize the body shapes of the Elderly Women focusing on the lower half, we grouped the target subjects using the nested approach by the average standard deviation and the factor analysis minimal diffusion method. Accordingly, type 1 and 2 had 36 members respectively and type 3 had 43 members. In this study, two Elderly Women subjects with standard body shape falling under the type 1 were selected as the subjects. 2. In the second trial evaluation for the prototype panty for the Elderly Women 32 items for appearance test and 3 items for functional test were evaluated. The scores in leg, sideline and hip were shown high and the balance between the parts was maintained very well. In the functional test, the panty used to be too tight for the leg curve but in the second trial it was improved, too. In each item, the second trial test showed better score than the first trial test. Conclusively, the most optimal panty prototype for the Elderly Women was proposed according to the trial test result.

  • Objectives: The purpose of the study was to investigate the perception of clinical trials of dental hygienist. Methods: A self-reported questionnaire was filled out by 126 dental hygienists in Seoul, Kyonggi and other area from October 1 to November 15, 2012. The instrument of the study was adapted from Jung and reconstructed. The questionnaire consisted of general characteristics of the subjects(9 questions) and recognition for clinical trials(10 questions). Recognition for clinical trials instrument included recognition for clinical trial conception(2 questions), objective recognition(5 questions), and subjective recognition for clinical trial(3 questions). The instrument was score by Likert 5 scale and Cronbach alpha was 0.936 in the study. Data were analyzed by SPSS 20.0 program and set at p<0.05. Independent t-test, chi-square test, one way ANOVA, and post-hoc Duncan test were done. Results: Those who had higher ages and higher education tended to have longer clinical careers(p<0.05). There was a significant difference in clinical trials between the level of education, clinical dental hygienists and professors. The differences in problem perception for activation of clinical trial according to workplace appeared to lack of publicity and inadequacy of facilities(p<0.05). Conclusions: To improve the perception of the clinical trials in dental hygienists, it is necessary to prepare the human resources programs, the additional curricula, continuing education courses and active publicity.

Legal issues of obtaining informed consent in pharmaceutical clinical trial as human material research : Focusing on the use of statutory form (인체유래물연구에 해당되는 의약품임상시험에서 동의 획득 기준의 법적 문제: <인체유래물연구동의서> 법정 서식의 사용을 중심으로)

  • In pharmaceutical clinical trials as human material research, the collection, use, storage and provision of human materials must be in accordance with the criteria stipulated in 「Bioethics and Safety Act」, except in the case that some criteria about it is in the law related to clinical trials such as 「Pharmaceutical Affairs Act」 and 「Enforcement Rule on Safety of Drugs, etc.」 so these take precedence over. Under 「Bioethics and Safety Act」, the core aspect of the legal standard for obtaining informed consent is the use of statutory form . The use of statutory form ensure that both those who obtain informed consent and those who give it can know the contents contained this form as well as recognize its importance. Thus, the person who has the right to informed consent can sign the statutory form after correct understanding of the contents. In reality, however, some researchers and IRB members determine that only the main informed consent form is to be used because most of contents on statutory from are included in the main informed consent form. Some other researchers and IRB members judge that the use of statutory form is not needed if human materials may only be used for laboratory testing and the rest will not be stored and provided for future use. Most of these determination and judgement is based on the interpretation of the Korea National Institute for Bioethics Policy(hereafter, KoNIBP) on IRB Information Portal Site. But, it is questionable whether the KoNIBP's interpretation is legally valid and the KoNIBP is the legal entity having authority to interpret existing statute. In some cased not only using the main informed consent form including enough information about the collection, use, storage and provision of human materials but also collecting necessary minimum human materials, and discarding the rest, unusing the statutory form may not cause the problem to respect and protect the research participant's rights. Therefore, the provision stipulating the criteria about the use of statutory form as the legal standard of obtaining informed consent that applies all human material research without exception should review to revise. At least, straighten out the confusion surrounding whether or not the statutory form is to be used, before the revision of related provision, considering the logical opinions of some researchers and IRB Members, the Ministry of Health and Welfare as the legal entity having authority to interpret existing statute should represent its opinion about permission of the acceptable exceptions.
