Purpose: The purpose of this study is to investigate the stress response and sleep state of the new patients who visit the hospital for prosthodontic treatment due to tooth loss to make reference to further treatment direction. Materials and methods: Examinations, consultations, and surveys were conducted on 236 patients (94 males, 142 females, and 24-86 years old), who newly registered at the department of prosthodontics at Pusan national university hospital, for 2 years from 2018. The number of remaining teeth, edentulous arch, possibility of mastication, and future prosthetic treatment directions were recorded. The visual analogue scale (VAS), stress response inventory (SRI) and Insomnia severity index (ISI) were used as tools to measure patient's subjective discomfort, stress response, and sleep status. Results: Among the entire prosthodontic patient group, the average value of 'fatigue' was significantly higher among the 7 items of SRI, and the value of 'aggression' was significantly lower (P<.001). There are a significant difference between the edentulous and full dentition in the oral discomfort value measured by VAS (P=.004). In cases where less than 20 teeth remain, mastication is impossible, and patients who are planning treatment with removable prostheses, VAS value and 'depression' and 'fatigue' values in SRI were higher than those in the reverse case (P<.05). The patients showed severe level in VAS value have high value of 'tension', 'somatization', 'depression', 'fatigue'and 'frustration'in SRI than non-serious patients (P<.05). Clinical insomnia occurred in 11.4% of all patients, and women had significantly lower sleep quality than men (P=.044). Patients with insomnia showed significantly higher scores on the VAS value and all 7 SRI items than those of normal sleepers (P<.05). Conclusion: The new prosthetics had high 'fatigue' value among the 7 items of SRI. The oral condition, number of residual teeth and mastication function and clinical insomnia affected oral discomfort and the stress response.

Objectives: The purpose of this study is to examine the safety of Korean medicine treatment in patients vaccinated with the AstraZeneca COVID-19 vaccine (ChAdOx1 nCoV-19/AZD1222). Methods: We investigated patients at Kyung Hee University Korean Medicine Hospital who were vaccinated with the AstraZeneca COVID-19 vaccine between June 1, 2021 and June 30, 2021. The safety of Korean medicine treatment was evaluated by examining adverse events that occurred within seven days of vaccination, including liver function and kidney function testing, assessment of the severity of adverse events, and examination of causality to vaccines and Korean medicine treatment. Results: Eleven patients vaccinated with the first dose of the AstraZeneca COVID-19 vaccine were included. A total of 19 adverse events were reported: 15 systemic adverse events, three local adverse events, and one alanine aminotransferase increase. The most commonly reported systemic adverse events were fatigue (4 cases, 36.4%), headache (4 cases, 36.4%), and myalgia (4 cases, 36.4%). All adverse events were rated below moderate (grade 2) in severity. Systemic and local adverse events were evaluated as definitely related to vaccination and unlikely to be related to Korean medicine treatment, while alanine aminotransferase increase was evaluated as unlikely to be related to either the vaccine or Korean medicine treatment. Aspartate transaminase, Blood urea nitrogen, and creatinine were measured within the reference range after vaccination. Conclusion: Our results suggest that the severity and frequency of adverse events in patients vaccinated with the AstraZeneca COVID-19 vaccine did not increase after Korean medicine treatment.

Mechanical joints such as bolted or riveted joints are widely used in structural components and the reliable determination of the stress intensity factors for corner cracks in mechanical joints is needed to evaluate the safety and fatigue life. This paper analyzes the mixed-mode stress intensity factors of surface and deepest points for quarter elliptical corner cracks in mechanical joints by weight function method and the coefficients included in weight function are determined by finite element analyses for reference loadings. The extended form of the weight function method for two-dimensional mixed-mode to three-dimensional is presented and the number of terms in weight function is determined by comparing the results for the different number of terms. The amount of clearance is an important factor in evaluating the severity of elliptical corner cracks in mechanical joints and even horizontal crack normal to the applied load is under mixed-mode in the case that clearance exists.

Purpose: The purpose of this study is to investigate nurses' role conflict and intention to remain and to identify factors that may influence this intention. Methods: Data were collected from 172 nurses in a 600-plus bed hospital on nurses' intention to remain, which included 47 items and nurses' role conflict, which included 82 items from a self-reported questionnaire. Data were analyzed by descriptive statistics and stepwise multiple regression using SPSS 22.0 Results: The mean of the role conflict frequency was 2.71(${\pm}.39$) and the mean severity was 2.86 (${\pm}.47$). The most significant item among the items of intention to remain was "a nurse's job is to help people." The intention to remain employed showed a significant difference in the duration of desired working period and subjective job satisfaction. The subjective job satisfaction of nurses was the most influential variable as a factor affecting the intention to remain, followed by frequency of role conflict in nursing practice. Conclusion: These results suggest that inadequate nursing environments in nursing practice require improvement and support the idea that nurses with positive attitudes of the nursing organization and theirs leaders reduce nurses' related fatigue.

In the development of a vibration-based condition monitoring system in gearbox, one of the most important research topics is a quantitative analysis and test of the effect of gear damage on vibration of gearbox. This paper presents the evaluation result of vibration condition indicator according to the gear tooth damage through the vibration test of gearbox. The dynamic load test was performed with high speed railway (KTX)'s gearbox. The vibration of gearbox was measured according to a rotational speed change with the common gear fault modes, such as pitting and tooth breakage. The characteristics and the possibility of applying of vibration condition indicator on condition monitoring system were analyzed. As a result, the value of most condition indicator is gradually increased with the severity of gear faults. The NA6 indicator shows a low variation with the rotational speed change and high sensitivity in accordance with the gear fault.

Premenstural dysphoric disorder(PMDD) imposing 4-5% of women is possibly caused by an enhanced responsiveness to the changes of sex steroid hormones and the decrease of serotonin, melatonin and GABA. The common clinical features between PMDD and depression, seasonal affective disorder, panic disorder and anorexia nervosa suggest a relatedness between PMDD and each of them. The diagnostic criteria of DSM-IV-Tr for PMDD requires psychological symptoms, that commonly include irritability, anger, depression, mood swing, affect lability, tension, anxiety, fatigue and food craving. As of today, the best pharmacological treatment for PMDD is the selective serotonin reuptake inhibiter, and leuprolide, danazol, estradiol, spironolactone and bromocriptine are possible alternatives. Nonpharmacological treatments for patients with mild to moderate symptom severity are diet, exercise, light therapy, psychotherapy and keeping a diary.

Steel-concrete-steel (SCS) sandwich structures have important advantages over conventional concrete structures, however, bond-slip between the steel plate and concrete may lead to a loss of composite action, resulting in a reduction of stiffness and fatigue life of SCS sandwich structures. Due to the inaccessibility and invisibility of the interface, the interfacial performance monitoring and debonding detection using traditional measurement methods, such as relative displacement between the steel plate and core concrete, have proved challenging. In this work, two methods using piezoelectric transducers are proposed to detect the bond-slip between steel plate and core concrete during the test of the beam. The first one is acoustic emission (AE) method, which can detect the dynamic process of bond-slip. AE signals can be detected when initial micro cracks form and indicate the damage severity, types and locations. The second is electromechanical impedance (EMI) method, which can be used to evaluate the damage due to bond-slip through comparing with the reference data in static state, even if the bond-slip is invisible and suspends. In this work, the experiment is implemented to demonstrate the bond-slip monitoring using above methods. Experimental results and further analysis show the validity and unique advantage of the proposed methods.

Objectives: This study was conducted to analyze the symptoms and care needs of home-based hospice palliative patients in Busan and to provide a basic reference for developing practical guidelines for their care. Methods: By examining the registration cards of 409 hospice palliative patients, who were registered in community health centers in Busan as of 2016, this study retrospectively analyzed their characteristics, symptoms and care needs. Results: The average age was 70.6 years, 59.4% were receiving medical benefits, and 48.4% lived alone. As per the data obtained from the Palliative Performance Scale, many were able to mobile. Fatigue was the most severe and depression and anxiety were reported together, and their care needs were also high. Most subjects reported mild or low pain, but care needs were high. Furthermore, the medical benefits group showed a high level of symptoms and care needs across areas. Conclusions: To help subjects to live in their homes for as long as possible, it is necessary to identify symptoms and care needs and provide services in accordance with their severity and situation. Thus, it is necessary to develop practical guidelines for standardized community hospice palliative care services.
