Purpose: Bruxism is commonly considered a major risk factor for temporomandibular disorders (TMD), and the psychosocial factors had been one of the etiologic factor of bruxism. But there are still unsolved issues on the relationship between sleep bruxism and TMD and the etiologic factors of bruxism. This study is aim to evaluate the clinical and psychosocial characteristics according to diagnostic grade of bruxism in TMD patients. Methods: Three hundred subjects were enrolled who were under the stabilization splint therapy for TMD. Recently international consensus proposed a diagnostic grading system of "possible", "probable", and "definite" sleep or awake bruxism for clinical and research purpose. According to their suggestion, we classified these subjects as self-reported bruxism (SRB) and wear facet bruxism (WFB). We investigated the clinical characteristics (sex, age, chief complaint, pain duration, visual analogue scale), sum of tenderness (temporomandibular joint, masticatory muscles, cervical muscles), diagnosis of TMD according to research diagnostic criteria (the Research Diagnostic Criteria for Temporomandibular Disorders, RDC/TMD), headache, subjective sleep quality (Pittsburgh Sleep Quality Index, PSQI), and psychosocial characteristics (Symptom Checklist-90-Revised, SCL-90-R) in enrolled subjects. We compared the clinical and psychosocial characteristics between these bruxism groups. Results: There were no significant correlation between self-reported and WFB (p=0.13). SRB subjects more reported pain as a chief complain than subject who did not report bruxism (p=0.014). The mean score of global PSQI was significantly higher in SRB than in did not report positively subjects (p=0.045). The mean score of anxiety and phobic anxiety was significantly higher in SRB than in did not reported positively subjects (p=0.045, p=0.041). Conclusions: Although bruxism is regarded as risk factor of TMD, this study showed inconsistent result between SRB and clinically detected bruxism by wear facet on slpint. We suggest that the clinician should consider with extreme caution when they assess SRB.

Purpose: Croup is a common pediatric respiratory illness with symptoms of varying severity. Moreover, epiglottitis is a rare disease that can rapidly progress to life-threatening airway obstruction. Although the clinical course and treatments differ between croup and epiglottitis, they are difficult to differentiate on presentation. We aimed to compare the clinical characteristics of croup and epiglottitis in Emergency Department patients. Methods: The 2012 National Emergency Department Information System database of 146 Korean Emergency Departments was used to investigate patients aged ${\leq}18years$ presenting with croup or epiglottitis. Results: We analyzed 19,374 croup patients and 236 epiglottitis patients. The male:female sex ratios were 1.9:1 and 2.3:1 and mean ages were $2.2{\pm}2.0$ and $5.6{\pm}5.8years$, respectively. The peak incidence of croup was observed in July and that of epiglottitis was observed in May. The hospitalization rate was lower in croup than in epiglottitis patients, and the proportion of patients treated in the intensive care unit was lower among croup patients. The 3 most common chief complaints in both croup and epiglottitis patients were cough, fever, and dyspnea. Epiglottitis patients experienced dyspnea, sore throat, and vomiting more often than croup patients (P<0.05). Conclusion: Both groups had similar sex ratios, arrival times, 3 most common chief complaints, and 5 most common comorbidities. Epiglottitis patients had a lower incidence rate, higher mean age of onset, and higher hospitalization rate and experienced dyspnea, sore throat, and vomiting more often than croup patients. Our results may help in the differential diagnosis of croup and epiglottitis.

Objectives : This study was planed to evaluate clinical status of the alopecia patients who had visited Korean medicine clinic. And the result from this study would provide a standard in Korean medical diagnostic and classification method of alopecia. Methods : Clinical records of 183 patients with alopecia seen from January 2004 to April 2005 at Korean medical clinic was examined. They were classified into 4 different types according to chief complains besides alopecia by 2 Korean medical doctors. Results and conclusions : We made clinical analysis of patients of alopecia from January 2004 to April 2005. Among the alopecia patients who visit Korean medical clinic, people age between 20 and 30 had high ratio. The duration from the recognition of initial hair loss to the time of the first visit to the Korean medical clinic was less than 12 months in 20.8%(38/138), and less than 60 months in 72.2% (132/183). The condition of alopecia was more worse than other alopecia patients who visit the west medical clinic. Also the ratio with increased temperature of face or scalp is chief complaint except alopecia in alopecia patients was high in men and the ratio with dysfunction of digestive system or chronic weakness was high in women. Among the incidence of alopecia, the androgenic alopecia was most in number; 43.7%(80/183) and the sex distribution showed 83 men and 100 women.

아프리카의 많은 국가들이 민주화를 경험함에 따라 입헌주의의 중요성이 점점 더 부각되고 있다. 본 논문은 아프로바로메터 여론조사 데이터를 이용해 아프리카인들이 사법부에 대한 신뢰도 형성에 영향을 미치는 요인이 무엇인가를 경험적으로 분석하고 있다. 민주주의 체제에서 사법제도가 효과적으로 실현되기 위해 시민의 사법부에 대한 높은 신뢰도는 핵심적 요소 중 하나이다. 기존 연구들이 사법부의 기능이나 소송절차 등에 초점을 맞춰왔음에 비해 본 연구는 아프리카인들이 자국의 대통령이 헌법이나 사법제도를 어느 정도 존중하는가와 본인들이 일상생활에서 느끼는 법치의 수준, 법관의 부패 수준 등이 사법제도에 대한 그들의 신뢰도 형성에 영향을 미친다는 것을 경험적으로 보여준다. 분석 결과는 행정부의 수장(대통령 혹은 수상)이 사법제도나 헌법을 존중하는 모습을 보여줄수록, 아프리카인들이 법치가 공정하게 이루어진다고 평가할수록, 또한 아프리카인들이 부패한 법관이 많지 않다고 생각할수록 자신이 속한 국가의 사법부를 더 신뢰한다는 것을 보여준다. 본 연구는 과도기적 체제전환을 경험하는 신생민주주의 국가에서 법과 정치 사이에 긴장이 발생할 수있으며, 사법에 대한 시민들의 이상과 정치의 현실이 과도기 정의에 상호 교차적으로 부담을 줄 수 있다는 것을 보여준다.

After the construction participants system is abolished, expectations are high for its consequences such as liquidating paper-companies, holding back low price contracts, and improving multi-stepwise subcontract structure. However, the professional construction firms have been took responsibilities and obligations as businessmen employing the chief workmen and construction workers. For this reason, it is expected that they will be charged a great deal of expenses such as increase in labor management services and laborers, the occurrence of an retirement grants, insurance fees, etc. Since the hold on power of field managers are getting weaker toward the construction workers, it is most likely to have loss in efficiency of production in the long term. Therefore purpose of this research is to analyze difficulties and the point at issues with which professional construction firms are undergoing after abolishing the construction participants system by investigating on the actual condition in the field management. For this research, we got a grip on the actual condition and analyzed the rise of a primary factor on reinforced concrete construction.

Triage is a practice of accurately prioritizing patients in emergency department (ED) based on their medical condition to provide them with proper treatment service. The variation in triage assessment among medical staff can cause mis-triage which affect the patients negatively. Developing ED triage system based on machine learning (ML) techniques can lead to accurate and efficient triage outcomes. This study aspires to develop a triage system using machine learning techniques to predict ED triage levels using patients' information. We conducted a retrospective study using Security Forces Hospital ED data, from 2021 through 2023 during Hajj period in Saudia Arabi. Using demographics, vital signs, and chief complaints as predictors, two machine learning models were investigated, naming gradient boosted decision tree (XGB) and deep neural network (DNN). The models were trained to predict ED triage levels and their predictive performance was evaluated using area under the receiver operating characteristic curve (AUC) and confusion matrix. A total of 11,584 ED visits were collected and used in this study. XGB and DNN models exhibit high abilities in the predicting performance with AUC-ROC scores 0.85 and 0.82, respectively. Compared to the traditional approach, our proposed system demonstrated better performance and can be implemented in real-world clinical settings. Utilizing ML applications can power the triage decision-making, clinical care, and resource utilization.

Objective: This study aimed to report the improvement of a patient with chronic insomnia who was treated with Baekho-tang based on the Shanghanlun disease pattern identification diagnostic system (DPIDS). Methods: The patient's symptoms were checked on days 19, 37, and 52 after taking Baekho-tang. Chronic insomnia was evaluated by the degree of insomnia, hours spent asleep, and the number of times the patient woke up during the night, which were all assessed by a visual analog scale (VAS) with the Leeds Sleep Evaluation Questionnaire. In addition, new clinical implications for the interpretation of the 350th Shanghanlun provision were reviewed. Results: After administering Baekho-tang for 52 days, based on the 350th Shanghanlun provision according to the DPIDS, the VAS score decreased from 10 to 1. Conclusions: The patient recovered from chronic insomnia. This case report suggests that the words "滑," "厥," and "裏" in the 350th provision of Shanghanlun mean physical and psychological causes of insomnia. In addition, Baekho-tang had a therapeutic effect in improving the chief complaint of the patient. Therefore, the interpretation of the 350th Shanghanlun provision requires a new definition that includes the patient's lifestyle, family conflict, and past history of the patient as a cause of chronic insomnia.
