This report presents 2 cases of sinus fungus ball and describes the characteristic radiographic features of fungus ball in the maxillary sinus. Two female patients, aged 62 and 40 years, sought consultations at a dental hospital for the treatment of dental implants and tooth pain, respectively. Panoramic radiography and small field-of-view(FOV) cone-beam computed tomography (CBCT) did not provide detailed information for the radiographic diagnosis of fungus ball due to the limited images of the maxillary sinus. Additional paranasal sinus computed tomographic images showed the characteristic features of fungus ball, such as heterogeneous opacification and intralesional calcification of the maxillary sinus. The calcified materials of the fungus balls were located in the middle and superior regions of the maxillary sinus. It is necessary to use large-FOV CBCT for the detection of calcified materials in the upper maxillary sinus to confirm the diagnosis of fungus ball.

We report a rare case of primary tracheal malignent melanoma documented by careful clinical examination. Differentiation between primary and metastatic malignant melanoma is very difficult We conclude that this tracheal tumor is a primary malignant melanoma based on characteristic pathologic features and the exclusion of the possibility of spontaneous regression of the primary site by patient's history and physical examination.

This study examined the perception of the royal family and scholars, focusing on the records of the royal family and literary collections in the late Joseon Dynasty, and attempted to present the process of accepting this content in Korea through domestic and foreign medical documents and other literature. The perception of this content in the late Joseon Dynasty can be said to be a characteristic to the history of acupuncture and moxibustion in the Joseon period. This seems to have occurred after the middle of the Joseon Dynasty, when both acupuncture and medicine were commonly performed on the king. This content was generally recognized by Joseon's scholars because it had been in books read by the scholars before it was mentioned directly in the medical book. Korean medical books were influenced by Uihakyimmun, and this content continued steadily in various medical books. Since the books containing this content were test subjects for the medical exam, it can be assumed that they were generally accepted by doctors in the late Joseon Dynasty.

It has become a general idea today that the characteristics of medicine should be considered as a basis when discussing a medical personnel's duty of care and whether or not it has been violated, and when discussing its duty of explanation and whether or not it has been fulfilled in medical practice. However, in the discussion of its characteristics, some shortcomings still exist, so the need for a re-discussion has been raised. Firstly, existing discussions on characteristics have failed to comprehensively grasp and explain the characteristics of medical practice. Secondly, in some researchers' arguments, there are discrepancies between the terms used to express characteristics and their conceptual definitions or content. Thirdly, the lack of exemplified cases that reflect the characteristics of medicine - especially Supreme Court precedents - has led some to think negatively about the recognition and reflection of certain characteristics. In my early writings, I have described five characteristics of medical practice: 'conflict in medical goals', 'initiating appropriate medical actions (progression of illness)', 'dynamics of medical intervention (diversity of symptoms)', 'diversity of medical effects', 'inherent risk of medical treatment (invasiveness)'. In this paper, keeping in mind the reasons for the need for reconsideration, I aim to analyze the characteristics of medicine in detail and cite key parts of representative Korean Supreme Court precedents that reflect each characteristic. The characteristics of medicine extracted from this paper are; There are ten factors, including the legitimacy of the essence of medical practice, timeliness of medical execution, dynamics of medical progress, diversity of medical effects, risk of medical invasion, non-uniformity of medical methods, limitations of medical capabilities, intervention of the medical subject, high degree of medical standards, and maldistribution of medical data.

Loeys-Dietz syndrome (LDS) is an autosomal dominant disorder caused by heterozygous mutations in the genes encoding transforming growth factor-${\beta}$ receptor type 1 or 2. It is typically characterized by a triad of hypertelorism, cleft palate or bifid uvula, and arterial tortuosity with aneurysm or dissection. Characteristic vascular abnormalities such as tortuosity, aneurysms, dissections, and stenosis are the most severe complications of LDS and can occur in the neurovascular system. We report a 5-year-old boy who presented with headaches and neurovascular abnormalities and was diagnosed with LDS with a novel mutation of the TGFBR1 gene. It is the first Korean report of neurovascular abnormalities in LDS.

We investigated the therapeutic potential of bone marrow-derived mesenchymal stem cell-conditioned medium (BMSC-CM) on immortalized renal proximal tubule epithelial cells (RPTEC/TERT1) in a fibrotic environment. To replicate the increased stiffness characteristic of kidneys in chronic kidney disease, we utilized polyacrylamide gel platforms. A stiff matrix was shown to increase α-smooth muscle actin (α-SMA) levels, indicating fibrogenic activation in RPTEC/TERT1 cells. Interestingly, treatment with BMSC-CM resulted in significant reductions in the levels of fibrotic markers (α-SMA and vimentin) and increases in the levels of the epithelial marker E-cadherin and aquaporin 7, particularly under stiff conditions. Furthermore, BMSC-CM modified microRNA (miRNA) expression and reduced oxidative stress levels in these cells. Our findings suggest that BMSC-CM can modulate cellular morphology, miRNA expression, and oxidative stress in RPTEC/TERT1 cells, highlighting its therapeutic potential in fibrotic kidney disease.

The purpose of the study was to discuss amrketing strategy for oriental hospital, by making a comparative analysis of how hospital user satifaction was affected by hospi시 choice motivation between oriental hospital users and western hospital. The data usel in this study was the Korea Isititute of oriental medicine(1999)'s study on utilization of oriental medical care. And and interview was hold with outpatients who visited around march to April, 1999, at each an oriental hospital and a westen hospital in Seoul and in Wonju city, Kongwon province. The collected data were analyzed by SPSS program. The factor analysis of hospital choice motivation was made by figuring out facor's mean value, and T-test and ANOVA were employed to find out what difference was made by sociodmographic charcteristics to the factors. Also, the multiple regression analysis was carried out to examine what gave an impact on hospital user satisfaction. The findings of this study were as follows; First as a result of making a factor analysis against hospital choice motivation to find out what kind of differenc there was between oriental hospital user motivation and western hospital and person factors. Among them, the hospital charcteristics, preception, personal and person factors. Among them, the hospital charcteristics appered to have the biggest effect of hospital choice motivation. Second, as a result of making comparison between oriental oriental hospital user satisfaction and werterm hospital user satisfaction, there was a singificant between their satisfaction at treatment time, kindness and relative kiness aginst the pther hospital. The oriental level combining 6 items. The geneal satisfaction level combining 6itmes tured out to have reliability of chronbach $\alpha$=0.7126. As a result of examining how mech the general satifaction level depended on sociodemographic characteristics, ther was found be significantly affected by age, marital status, educational background or hospital type. Those who a spouse or a lower educational background or the oriental hospital users got better score. Third, the multiple regression analysis was made to find out what factors affected western and oriental hospital user satisfaction, As a result, the waiting time, experience of other medical facilities and hospital characteristic variable were identified as a key factor on which westerm hospital user satisfaction depended. In conclusion, the oriental hhspital user expressed more staisfaction than the weshren hospital users. Then the characteristic factor played a singificant role in user satisfaction, which included hospital facilities, kindness of herb doctor and employees, or hospital reputation of credibility. in order to raise hospital user datisfaction, it seemed necessary to pay more attention to hospital characteristic factor rather than to perception factor.

Cardiac tamponade due to purulent pericarditis with a characteristic greenish fluid is rare in this antibiotic era. It is highly fatal despite early diagnosis and advanced treatment. Gram-positive cocci are the leading cause of purulent pericarditis, which usually results from a direct or hematogenous spread of organisms to the pericardium from the primary foci of infection. We describe an index case of rapidly developing pericardial tamponade caused by oropharyngeal polymicrobial infection in the absence of a primary source of infection in a 62-year-old man, who was successfully managed with emergency large-volume pericardiocentesis followed by pericardiectomy.

It is well-known fact that Korean medicine is related to Taoism. Dong-$\breve{u}$ibogam(東醫寶鑑) was written by Heo-Jun(許浚) in Jo-seon(朝鮮) dynasty. Heo-Jun complied all of past studies on Korean medicine in this book. On the basis of Naegyoung(內徑), he accepted the theory of four eminent physicians of the K$\breve{u}$m and Won Dynasty(金元時代) in ancient China and Eubangyouchui(醫方類聚), $\breve{U}$irimch'waryo(醫林撮要), Hyang-yakjips$\breve{o}$ngbang(鄕藥集成方) in Jo-seon. Especially, Dong-$\breve{u}$ibogam is so characteristic of Taoism than any other medical books written in China or Korea before. In this study, I researched the relation between Dong-$\breve{u}$ibogam and Taosim on the views of authors, organization, reference hooks, contents.
