Objectives We aimed to characterize the results obtained from Korean medical examinations and questionnaires on the quality of sleep. Methods The quality of sleep was measured using the Pittsburgh sleep quality index in 400 subjects. Afterwards, heart rate variability (HRV) measurements were done, along with the analyses for tongue color, teeth marks, and tongue coating through the tongue diagnosis system. A questionnaire about body's heat, cold and sweating conditions, and the perceived stress scale (PSS) were performed. Finally, correlations between all these indicators and the sleep quality were analyzed. Results As the quality of sleep decreased, the sympathetic nervous system was stimulated. The subjects who had the blue-purple colored tongue experienced decreased quality of sleep. The quality of sleep was also deteriorated in the subjects who usually feel cold and hot easily, sweat a lot, and feel a lot of discomfort. According to the PSS questionnaire, the higher the stress level is, the lower was the quality of sleep. Conclusions We obtained meaningful results by comprehensively analyzing the sleep quality, HRV, tongue diagnosis, heat and cold conditions, sweating, and stress conditions. In particular, the sleep quality had a significant correlation with the rest of the indicators.

Since SF₆ gas was discovered in the early 1900s, it has been widely used as an insulation material for electrical equipment. While various indicators have been developed to diagnose oil-immersed transformers, there are still insufficient indicators for the diagnosis of gas-insulated transformers. When necessary, chemical diagnostic methods can be used for gas-insulated transformers. However, the field suitability and accuracy of those methods for transformer diagnosis have not been verified. In addition, since various types of decomposition gases are generated therein, it is also necessary to establish appropriate analysis methods to cover the variety of gases. In this study, a gas-insulated transformer was diagnosed through the analysis of decomposition gases. Reliability assessments of both simple analysis methods suitable for on-site tests and precise analysis methods for laboratory level tests were performed. Using these methods, a gas analysis was performed for the internal decomposition gases of a 154 kV transformer in operation. In addition, simulated discharge and thermal fault experiments were demonstrated. Each major decomposition gas generation characteristics was identified. The results showed that an approximate diagnosis of the inside of a gas-insulated transformer is possible by analyzing SO₂, SOF₂, and CO using simple analysis methods on-site. In addition, since there are differences in the types of decomposition gas generation patterns with various solid materials of the internal transformer, a detailed examination should be performed by using precise analysis methods in the laboratory.

The disease concept of interstitial lung disease with idiopathic pulmonary fibrosis at its core has been relied on for many years depending on morphological classification. The separation of non-specific interstitial pneumonia with a relatively good prognosis from usual interstitial pneumonia is also based on the perception that morphology enables predict the prognosis. Beginning with dust-exposed lungs, initially, interstitial pneumonia is classified by anatomical pathology. Diagnostic imaging has dramatically improved the diagnostic technology for surviving patients through the introduction of high-resolution computed tomography scan. And now, with the introduction of therapeutics, the direction of diagnosis is turning. It can be broadly classified into to make known the importance of early diagnosis, and to understand the importance of predicting the speed of progression/deterioration of pathological conditions. For this reason, the insight of "early lesions" has been discussed. There are reports that the presence or absence of interstitial lung abnormalities affects the prognosis. Searching for a biomarker is another prognostic indicator search. However, as is the case with many chronic diseases, pathological conditions that progress linearly are extremely rare. Rather, it progresses while changing in response to environmental factors. In interstitial lung disease, deterioration of respiratory functions most closely reflect prognosis. Treatment is determined by combining dynamic indicators as faithful indicators of restrictive impairments. Reconsidering the history being classified under the disease concept, the need to reorganize treatment targets based on common pathological phenotype is under discussed. What is the disease concept? That aspect changes with the discussion of improving prognosis.

The Educational Restitution Rate is an important parameter that determines the quality of university education. This paper analyzed data from 148 private universities over the 10 years from 2009 to 2018 using data mining techniques in Korea. A significant causal relationship is detected in the fixed effect model as a result of the panel estimation. And the scale of faculty expansion and fund management, which are the university evaluation indicators, and the size of basic funds, respectively, have a positive effect on the ERR, which is within the confidence interval. In the analysis, the more private universities improve the tuition dependence rate, the more decisively positive affecting ERR. As a result of nonparametric regression estimation, when the faculty expansion ratio is reinforced, the effect of economies of scale is detected in some sections, the improvement of the tuition dependence rate, and the result value is generated through the improvement that results are derived at a certain point in time. We hope that the university based on this study can be a basic Indicators for the diagnosis of basic competencies and policy of student-centered education.

연구목적: 최근 대형 사회재난이 발생하면서 사회재난 안전도 진단에 대한 필요성이 요구되며 행정안전부에서 지역 안전지수, 국가안전대진단 등 지역의 안전도 등급을 계산하여 매년 공표하고 있다. 기존의 안전도 진단 시스템은 등간격 혹은 정규분포를 이용해서 획일화된 방법으로 등급화를 진행하여 위험지도를 작성하고 있다. 연구방법: 하지만 등간격 기법은 위험등급을 객관적으로 분석할 수 있지만 분포가 한쪽에 치우쳐있는 경우 위험등급을 분류하는데 한계가 있으며 z-score 기법은 모집단이 정규분포를 따르지 않으면 신뢰도가 떨어지는 문제가 있다. 지표별로 통계 데이터의 분포가 상이하기 때문에 데이터 분포별로 가장 적합한 등급화를 적용해야한다. 연구결과: 따라서 본 논문에서는 재난 지표의 데이터를 분석하여 각 지표마다 최적화된 등급화를 진행하고자 기존의 등간격 기법과 네츄럴브레이크 기법을 비교 및 적합한 방법을 제시하였다. 결론: 그 결과 기존의 등급화 기법과 다르게 적용된 것은 6새 지표 중 3개에 해당하였다.

Oral spindle cell/sclerosing rhabdomyosarcoma (SCRMS) with anaplastic lymphoma kinase (ALK) expression is extremely rare, and its diagnosis is very challenging in the absence of clinical or pathological indicators. This case presented with gingival swelling and alveolar bone resorption and was suspected clinically to be periodontitis. A biopsy was performed and, due to immunoreactivity with ALK, the patient was misdiagnosed with inflammatory myofibroblastic tumor. However, based on the combined histological and immunohistochemical features, a revised diagnosis of SCRMS with ALK expression was finally concluded. We believe that this report makes a significant contribution to the precise diagnosis of this rare disease for proper treatment.
