Archives should provide a web-based archival information service with good usability based on the understanding of users' needs. Thus, this study analyzed the usability of the National Archives of Korea (NAK) website's search service through expert and usability evaluations for various users and suggested improvement plans. A literature review, heuristic evaluation, one of the usability expert evaluation methods, and usability evaluation for users were performed. As a result of expert evaluation, the severity rating for the usability problem was highest regarding a match between the system and real world and the lowest in error prevention. In the usability evaluation, it was assumed that the user's background and whether the website's help was provided is associated with usability. Usability evaluation was conducted for 22 participants, including those majoring in records management, web/application developers, and people without such backgrounds. Furthermore, a presurvey, a five-second test, and search tasks were conducted in a row. The analysis based on usability components in ISO 9241-11: 2018, i.e., effectiveness, efficiency, and satisfaction, showed that web/application developers had the highest search effectiveness, and those majoring in records management showed high effectiveness only in the search for archival content services. Background factors did not affect efficiency, and the more familiar with the finding aids, the better the efficiency. Moreover, providing the website's help was found to be positively associated with effectiveness and satisfaction. This study suggests that the NAK website will offer a user-friendly interface and search function, expand help support, and display a consistent web interface.

Objectives Despite growing attention to anxiety in bipolar disorder (BD), little research has assessed anxiety symptoms in the course of BD. The current prospective follow-up study examines the influence of subjectively and objectively measured anxiety symptoms on the course of BD. Methods A total of 49 patients with BD were followed-up prospectively for average of one year at an average of four months interval. The Korean version of the Beck Anxiety Inventory (K-BAI), the Hamilton Anxiety Rating Scale, heart rate variability (HRV) were used to measure anxiety subjectively, objectively and physiologically. Participants were divided into high and low anxiety groups based on their K-BAI scores. Kaplan-Meier survival analysis was performed to compare the recurrence of mood episode, suicide attempt, emergency room visit, and psychiatric hospitalization between two groups. Mediators were investigated with Cox proportional hazards models. Results Compared to the low anxiety group, the high anxiety group reported significantly higher impulsiveness (p = 0.016) and lower high frequency component on HRV (p = 0.007) after controlling for severity of BD. Regarding survival analysis, the high anxiety group showed hastened depressive episode recurrence (p = 0.048) and suicidal ideation was the mediator of the hazard ratio (HR) 1.089 (p = 0.029) in the Cox model. Moreover, the high anxiety group showed a tendency of accelerated suicide attempt (p = 0.12) and impulsivity was the risk factor of suicide attempt (HR = 1.089, p = 0.036). Conclusions This interim analysis of prospective study suggests that high anxiety level in BD may anticipate unfavorable course. Further studies are needed to understand the multifactorial mechanism of anxious bipolar patients.

Objectives: This study aimed to comprehend the characteristics of Korean medicine patterns in relation to varying degrees of cognitive impairment in an elderly population. Methods: The dataset included 127 elderly individuals with cognitive impairment obtained from three Korean medicine hospitals between 2018 and 2021. The participants were categorized into two groups based on Clinical Dementia Rating-Sum of Boxes (CDR-SB) scores: those with questionable impairment (QI) and those with very mild dementia (VMD). A diagnostic framework for Korean medicine patterns encompassing Qi deficiency, Yin deficiency, Phlegm dampness, and Heat-fire was employed. Liver blood markers, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), and the AST/ALT ratio, were also analyzed. Results: The scores of the cognitive assessment tools (MoCA-K, MMSE-DS, and K-IADL) of the QI group significantly differed from those of the VMD group. CDR-SB exhibited a positive correlation with the scores of each pattern of Qi deficiency, Yin deficiency, Phlegm dampness, and Heat-fire, whereas ALT and AST values displayed negative correlations. Binomial logistic analysis, controlling for potential confounders, such as age, education years, body mass index, the presence of chronic disease, and the presence of medication, verified that the VMD group showed higher pattern scores and lower ALT and AST values than the QI group. Conclusions: Increases in pattern scores along with decreased AST and ALT levels might be indicative of more severe cognitive impairment.

Objectives This study aims to find out effect of Korean medicine treatment on managing thoracolumbar compression fractures through retrospective observational study. Methods Among hospitalized patients at the Department of Korean Medicine Rehabilitation from January 1st, 2018 to February 28th, 2023, a total of 24 inpatients who were diagnosed with thoracolumbar compression fractures and received Korean medicine treatment were included in this study. Numeric rating scale (NRS) was used for pain assessment and clinical variables such as sex, symptoms, age, thoracolumbar injury classification and severity (TLICS) scores were collected. For subgroup analysis to analyze factors affecting treatment response, we divided patients into responders and non-responders according to NRS change. For statistical analysis, we compared before/after hospitalization and analyzed distinct features between two groups. Results Most of the patients were in their 70s and 83.33% were female. Average hospitalization period was 24.54±11.91 days. All patients had back pain as their chief complaint and only 2 patients received surgeries. In TLICS, only 1 patient got score 6, which represented surgery indication. After Korean medicine treatment, NRS of almost every patient got lower significantly at the time of discharge (3.02±1.93) than admission (5.52±1.95). Comparing two groups, responders had lower NRS at the time of discharge and TLICS score of them were lower than non-responders. Conclusions Our results show that Korean medicine treatment for thoracolumbar compression fractures was effective in reducing pain. There were distinct clinical features such as age, past history, surgeries between those with significant improvement in pain scores and those who did not.

The purpose of this study was to propose a framework for developing test scenarios for issuance of conditional driver's licenses. The framework was composed of five stages. Initially, we reviewed the literature on traffic crash characteristics in terms of accident frequency and severity regarding the main factors of crashes caused by older drivers. In the second stage, the characteristics of crashes attributed to non-elderly, early elderly, and late elderly drivers were analyzed using data obtained from the Traffic Accident Analysis System (TAAS), and crash types for elderly drivers were derived. In the third stage, black box videos of high-risk crash types were analyzed to derive crash stories that described the circumstances in which crashes occurred. In the fourth step, crash situations were classified by rating the types of crash stories derived to develop various scenarios. Step 5 involved creating a scenario by applying the PEGASUS 5-Layer format, which has recently been used to develop test scenarios for autonomous vehicles. The results of this study are expected to be used as a basis for developing driving ability evaluation scenarios for the issuance of conditional driver's licenses.

Objectives: To evaluate the effectiveness of Mindfulness & Loving Beingness (M&L) psychotherapy combined with traditional Korean medicine in treating acute sleep disorders in patients hospitalized following traffic accidents. Methods: We applied traditional Korean medicine treatments in conjunction with various mindfulness meditation techniques from M&L therapy, including Resource Mindfulness and Nourishment Brief Therapy. This study was conducted on three patients who reported acute sleep disorder symptoms on the first day of hospitalization following a traffic accident. The effectiveness of these interventions was assessed using the PTSD Checklist for DSM-5 (PCL-5-K), Insomnia Severity Index (ISI), EuroQol 5-Dimension (EQ-5D), Numerical Rating Scale (NRS), and Patient Global Impression of Change (PGIC). Results: ISI and PCL-5-K scores showed significant improvements after treatment, indicating reduced sleep disturbances and stress symptoms. Additionally, EQ-5D and PGIC scores were enhanced, reflecting an overall improvement in quality of life. Conclusions: This study suggests that integrating M&L therapy with traditional Korean medicine could significantly improve symptoms in patients with acute sleep disorders following traffic accidents.

Objectives: This case study reports the effectiveness of Korean medical treatment in a patient with cyclic vomiting syndrome. Methods: A 29-year-old female Korean patient with cyclic vomiting syndrome received acupuncture, electroacupuncture, herbal medicine, and moxibustion for 2 weeks in hospital. Changes in symptoms were evaluated using the Gastrointestinal Symptom Rating Scale (GSRS), Visual Analog Scale (VAS), Index for Nausea, Vomiting, and Retching (INVR), Nausea Severity Scale (NSS), Nepean Dyspepsia Index-Korean version (NDI-K), quality of life using the Functional Dyspepsia Related Quality of Life questionnaire (FD-QoL), and gastric motility using electrogastrography (EGG). Results: Post-treatment, the patient showed high satisfaction and improvement in symptoms of nausea and vomiting. The following changes were observed in scores: GSRS: 23 to 19; VAS of nausea: 88 to 95; VAS of dyspepsia: 95 to 12; INVR: 13 to 1; NSS: 17 to 5; NDI-K: 107 to 78; and FD-QoL 84 to 27. We also found positive results in Channel 3 of EGG parameters, implying the improvement of gastric motility disorder. Conclusion: Korean medical treatment can be a therapeutic option for cyclic vomiting syndrome.

Objectives : This study was to assess the prevalence and its correlates of restless legs syndrome(RLS) in outpatients with bipolar disorder. Methods : A total of 100 clinical stabilized bipolar outpatients were examined. The presence of RLS and its severity were assessed using the International Restless Legs Sydrome Study Group(IRLSSG) diagnostic criteria. Beck's Depression Inventory(BDI), Spielberg's State Anxiety Inventory(STAI-X-1), Pittsburgh Sleep Quality Index(PSQI), Korean version Drug Attitude Inventory(KDAI-10), Subjective Well-Beings under Neuroleptic Treatment Scale-Short Form(SWN-K) and Barnes Akathisia Rating Scale(BARS) were used to evaluate the depressive symptomatology, level of anxiety, subjective quality of sleep, subjective feeling of well-being, drug attitude, presence of akathisia, respectively. Results : Of the 100 bipolar outpatients, 7(7%) were met to full criteria of IRLSSG and 36(36%) have at least one of the 4 IRLSSG criterion. Because of relatively small sample size, non-parametric analysis were done to compare the characteristics among 3 groups(full-RLS, 1 ${\geq}$positive RLS-symptom and Non-RLS). There were no significant differences in sex, age, and other sociodemographic and clinical data among 3 groups. BDI, STAI-X-1 and PSQI are tended to be impaired in RLS and 1 ${\geq}$positive RLS-symptom groups. Conclusions : This is the first preliminary study for studying the prevalence and its correlates of RLS in bipolar disorder. The results shows that relatively small proportion of RLS was present in bipolar disorder patients when compared to patients with schizophrenia. Same tendencies shown in schizophrenic patients were found that bipolar patients with RLS had more depressive symptoms, state anxiety and poor subjective sleep quality. Further systematic studies may be needed to find the characteristics of RLS in bipolar patients.

The purpose of this study was to identify the relationship between depression and physical health of the elderly and to provide fundamental data for programs which improve the health of this population. The subjects were 168 elderly people(55 years and older) who resided at home in Taegu. They were surveyed by interview using a closed- ended questionnaire. The survey was done from September 16 to October 16 in 2000. The instruments used in this study were general characteristics, Short form Geriatric Depression Scale(SGDS), Barthel Index, Muscular skeletal symptoms scale, Northern Illinois University's Health Self Rating Scale. The data were analyzed by using descriptive statistics, t-test, ANOVA, Pearson Correlation Coefficient, multiple regression with SPSS PC 10.0 version for Windows. The findings were as follows: 1. As compared 65-74 years elderly group, 75-84 years group was significantly higher score for depression(F=3.17, p=.026). As compared elderly group who has own spouse, the group who has no own spouse was significantly higher score for depression(t=- 2.44, p=.016). 2. The aged who have more limitation of Activities of Daily Living(ADL)(t=3.93, p=.000), pain of muscular skeletal symptoms(F=5.33, p=.002) and poor perceived health state(F=17.04, p=.000) showed the higher severity of depression than the aged who have not. 3. ADL correlated negatively with depression(r=- .293, p=.000), pain of muscular skeletal symptoms correlated positively(r=.251, p=.001), perceived health status correlated negatively(r=-.522, p=.000). 4. The combination of perceived health status and ADL explained 29.1% of the varience of depression. On the basis of the above findings the following recommendations are made; 1. Developing health programs is needed considering ADL, pain of muscular skeletal symptoms, perceived health status, demographic variables (age, spouse status) which have an significant effects on depression of the elderly. 2. In the following study, the use of the various scale is needed which reflects physical status of the elderly in home.

Objective：This study was carried out to evaluate the reliability and validity of the Korean form of the Children's Yale-Brown Obsessive Compulsive Scale(CY-BOCS). Method：Forty-two children with obsessive-compulsive disorder(OCD)(31 boys and 11 girls, aged 7 to 18 years) were assessed with CY-BOCS. Interrater agreement was assessed by two raters in subsample(n=20). discriminant and convergent validity were assessed by comparing CY-BOCS scores to Clinical Global Impression-OCD(CGI-OCD), Leyton Obsessional Inventory-Child Version (LOI-CV), State-Trait Anxiety Inventory for Children(STAI-C), and Child Depression Inventory(CDI). Results：Internal consistency was high, measuring 0.86 for the 10 items and total score. The intraclass correlations for the CY-BOCS total, obsession, and compulsion scores were 0.94, 0.94, 0.84, suggesting excellent interrater agreement for subscale and total scores. The CY-BOCS total score showed highest correlation with CGI-OCD(r=0.88), and significant correlation with LOI-CV(r=0.51), Trait Anxiety score(r=0.43), and CDI scores(r=0.49), but it was not correlated with State-Anxiety score(r=0.25). Conclusion：The results of this study indicate that the Korean form of CY-BOCS is a reliable and valid scale for rating obsessive-compulsive symptom severity.
