To suggest future directions for the improvement in the Institutional Review Board (IRB) review process and efficient operation of IRB, we have analyzed the IRB review results from 460 new research proposals submitted to the Review by the Convened IRB of the Keimyung University Dongsan Hospital IRB from January 2019 to July 2021. IRB is an independently established institutional committee to protect the human subjects by reviewing the research protocol in ethical as well as scientific aspects, so it is necessary to continuously contemplate the ethical versus scientific dilemma of 'what is ethical or scientific and what can actually protect human subjects.' Particularly, in this process, it is necessary to consider diverse ways to strengthen self-supervision through continuous Internal Audit rather than simple reporting outcomes. In addition, if it does not directly affect the protection of the human subjects, the discussion with the committee members is needed so that the comments such as administrative and typographical errors can be reduced as much as possible. Furthermore, as statistical analysis methods can have a significant impact on the safety of human subjects, if a legal basis and/or support related to statistics is provided for the composition of IRB members, a more specialized IRB review will be achieved.

The purpose of this study was to implement a program of combined muscle stregth and proprioceptive exercises and to examine the impacts of these exercises on functional ankle instability(FAI). Experiments were conducted with 30 adult males and females in their 20s, and the exercise programs were implemented three days per week for four weeks. FAI was defined as a feeling of giving way after an ankle sprain and having a Cumberland ankle instability tool score of 24 points or less. The study subjects were randomly assigned to either a control group, a muscle-strengthening exercise group, or a combined muscle-strengthening and proprioceptive exercise group consisting of 10 subjects each. A Biodex isokinetic dynamometer was used to assess the subjects'ankle strength at selected speeds of $60^{\circ}/sec$ and $120^{\circ}/sec$. The peak torque % body weight showed significant differences in plantar flexion, dorsiflexion, inversion, and eversion. There were also significant differences in proprioception. The results suggest that applying combined muscle-strength and proprioceptive exercises to subjects with FAI is a more effective intervention than applying only muscle-strengthening exercises.

In this paper, we propose a novel method to quantify the neural synchronization between subjects in the collaborative process through electroencephalogram (EEG) hyperscanning. We hypothesized that the neural synchronization in EEGs will increase when the communication of the operators is smooth and the teamwork is better. We quantified the EEG signal for multiple subjects using a representative EEG quantification method, and studied the changes in brain activity occurring during collaboration. The proposed method quantifies neural synchronization between subjects through bispectral analysis. We found that phase synchronization between EEGs of multi subjects increased significantly during the periods of collaborative work. Traditional methods for a human error analysis used a retrospective analysis, and most of them were analyzed for an unspecified majority. However, the proposed method is able to perform the real-time monitoring of human error and can directly analyze and evaluate specific groups.

Background: The importance of postural stabilization and cervical mobilization in subjects with pain from the anterior head posture is drawing more attention. However, studies on head and neck stabilizing intervention after mobilization are lacking. Objective: To examine the effects of Kinesiotaping and posture setting exercise on forward head posture (FHP). Design: Crossover Study Design Methods: The subjects were 17 male and female college students in their 20s with FHP. They were randomized into the Kinesiology taping group (KTG) with 9 subjects and posture stabilizing exercise group (PSEG) with 8 subjects. The intervention was conducted for 4 weeks, and changes in pain, craniovertebral angle (CVA), and proprioception were observed before and after intervention. Results: Pain was significantly reduced in the KTG and PSEG both before and after intervention. CVA and proprioception were significantly increased only in the PSEG. The differences in CVA and proprioception between the two groups were significant. Conclusions: These findings suggest that the application of posture setting exercise could decrease pain, proprioceptive error and increase CVA on FHP.

This study conducted a literature analysis to examine the overall trend of speech-language pathology in discourse research, focusing on studies on the topic of discourse from 2010 to 2023. Twenty-five papers were selected and analyzed in terms of research status, research subjects (age and subject type), and research methods (type and task). As a result, first, looking at the annual status of discourse research, it was confirmed that it is increasing starting from 2015 compared to 2010 to 2014. Second, the age of the research subjects and the types of experimental and control groups in the experimental study were examined. First, when analyzing the age of the subjects, research was actively conducted on school-age subjects (12 studies, 48.00%). When looking at the analysis of the types of experimental group subjects, the Normal group was the most (4 studies (19.04%)), and the control group subject type was also conducted with Normal as the control group (13 studies (61.90%)). It was the most. Third, in the analysis of research methods, it was found that the research type was very biased towards experimental studies, with 21 studies (84.00%). The type of research in terms of time was cross-sectional studies, which accounted for a high proportion of 21 studies (84.00%), and the research project used to evaluate discourse ability with a high proportion was discourse production, with a total of 12 studies (48.00%). This study comprehensively looked at discourse-related research related to language development and language disorders and sought to identify recent trends and the direction in which discourse-related research should move. The analysis of this study was limited to domestic papers. In follow-up research, we hope to understand the flow of research and discuss it, including overseas research related to discourse.

Purpose: This study aims to provide suggestions for improving the liberal arts curriculum for the 3-year emergency medical technology course by conducting a comparative research on the liberal arts curricula across 10 colleges. Methods: Various aspects of liberal arts subjects, such as basic directions set out by the curriculum, credit scores, and distribution, were studied. Results: Of the 10 colleges, 9 did not stated purpose of liberal arts education. All 10 offered courses including foreign language, computer, and self-management, however each subjects did not have reflections of course visions. Findings revealed the credit score ratio of liberal arts subjects to be relatively lower than the major subjects. Students had limited opportunity to choose liberal arts subjects, with only a small proportion of the course available for elective subjects. Most liberal arts subjects were completed in the first year. Subjects' experience was not expanded and deepened gradually. Subject choices often overlapped, with limited variety of available subjects. Conclusion: For competent emergency medical technicians, the 3-year emergency medical technology course should improve the quality of its liberal arts offerings. The study of liberal arts provides the opportunity to develop broad perspectives and mature attitudes.

The purpose of this study was to compare the onset times of muscle activities and the order of muscle firing in hamstring gluteus maximus, and lumbar erector spinae muscle during active hip extension between subjects with low back pain (LBP) and healthy subjects. Thirty subjects, 15 with LBP and 15 healthy subjects, participated in this study. Electromyographic activity was recorded during active hip extension in prone and standing position. Relative onset times of these muscle activities were determined. Similar muscle firing order in hamstring, gluteus maximus, and lumbar erector spinae muscle showed in both groups and positions. However, the onset time of gluteus maximus was significantly later in prone and standing active hip extension in subjects with LBP than in healthy subjects. The onset time of lumber erector spinae muscle activity was significantly delayed in subjects with LBP in standing active hip extension, The delayed onset times of gluteus maximus and lumbar erector spinae muscles' activities were probably related to LBP. Further studies are needed to identify whether the delayed onset times of gluteus maximus and lumbar erector spinae muscle activities are the contributing factors to LBP.

Hypertension is associated with cardiovascular disease. The environmental and genetic factors can cause the development of hypertension. In this study, the relationship between hypertension and family history of hypertension in Koreans was analyzed in consideration of serum fasting blood glucose levels and age. The study subjects were 2,484 subjects who had a medical examination at a university hospital. The main statistical analysis method was multiple logistic regression analysis. Hypertension prevalence was 16.4% of all subjects, and subjects with a family history of hypertension were 23.5%. The risk of hypertension was 2.36 times higher in subjects with a family history of hypertension than subjects without a family history of hypertension. In addition, in the subjects with fasting blood glucose levels more than 120 mg/dL, the risk of hypertension was 4.44 times higher in subjects with a family history of hypertension compared with subjects without a family history of hypertension. The relationship between family history and hypertension was slightly higher in the older group than in the younger group. To assess the association between hypertension and family history, further cohort study is necessary in the future.

This study categorized 100 female subjects over 65 years of age into two groups. The first group is called 'early stage of varus', which is when the gap between the knees is less than 5 cm. The second group is called 'progressive varus', which is when the gap between knees is 5 cm (or more). We then analyzed their lower body shapes and life status. The results were as follows. The average gap between knees in the early stage group and the progressive group was 3.3 cm and 6.2 cm. Direct and indirect measurements of their lower bodies showed that subjects in the progressive group had longer legs than the other group because their legs were bent outwards. Most of the subjects were found to live in western housing conditions, but maintained sedentary lifestyles. A total of 60% of the subjects thought that they were in bad health conditions and said that they found it difficult to move their knees dynamically; in addition, 63.6% of the subjects in the early stage group and 73.5% of the subjects in the progressive group suffered from arthritis. Subjects in the progressive group were more aware than the other group that their legs were bent outwards. They also responded that bent legs do harm to their appearance and make their lives uncomfortable. Most senior females with varus did not seek medical treatment and did not buy clothes that can help change their varus. However, 95% of the subjects responded they were in need for clothes that could straighten the varus-type.

The goal of this paper was to examine the qualify zygote-acquiring method for in-vitro culture and the in-vitro culture method of the acquired zygote from a technological perspective. We have reported the results on the introduction of foreign DNAs using the described culturing method. After performing in-vitro and surrogate eggshell culture on a zygote acquired from the abdomen of a hen, 25.8% hatchability was acquired. After microinjecting foreign DNAs into the acquired zygote and performing in-vitro and surrogate eggshell culture using the same method, 13.1∼11.7% hatchability was acquired. Having compared the developments of the control subjects and the experimental subjects, the viability of the experimental subjects on the 4∼5th day of culturing was much lower compared to that of the control subjects. This is a result that shows that the microinjection process of foreign DNAs might have a negative effect on the existence of the embryo; therefore, various technical attempts should be made to minimize such negative effects. Having microinjected foreign DNAs into the zygote of a hen to produce transgenic chickens, 3 transgenic founders were Produced and 70 G1 progeny were produced as a result of the progeny test that had been performed to the present.
