Objective : This study aimed to investigate the characteristics of the early maladaptive schemas in patients with panic disorder. Methods : Patients (n=35) included people who had met the DSM-IV-TR criteria for panic disorder. The normal control group (n=35) were those people who had no psychiatric disorder and had never experienced panic attack. The early maladaptive schemas and the severity of depression and anxiety were assessed by the Young Schema Questionnaire Short-form (YSQ-SF), the Beck Depression Inventory (BDI), and the Spielberger State-Trait Anxiety Inventory (STAI). Results : The scores on the STAI-S, STAI-T, and BDI were significantly higher in the patient group. Compared to the control group, the scores of vulnerability to harm and illness, and abandonment/instability schemas were significantly higher in the patient group. In the patient group, defectiveness/shame and subjugation schemas were found to predict BDI, dependent/incompetence, abandonment/instability schemas were found to predict STAI-S, and vulnerability to harm and illness, and abandonment/instability schemas were found to predict STAI-T. In normal controls, failure and insufficient self-control/self-discipline, failure, and emotion inhibition schemas were found to predict BDI, STAI-T, and STAI-S. Conclusions : Vulnerability to harm and illness and abandonment/instability schemas may be characteristic schema in patients with panic disorder.

We was investigate the dosimetric characteristics of the virtual wedge and it compared to the conventional fixed wedge. Also we was evaluate the quality factor of the experimental multi-channel dosimetry system for virtual wedge. Recently virtual wedge technique and wedge fraction methods are available through the computer controlled asymmetric collimator or the independent jaw in medical linear accelerator for radiation therapy. The dosimetric characteristics are interpreted by radiation field analyzer RFA-7 system and PTW-UNIDOS system. Experimental multi-channel dosimetry system for virtual wedge was consists of the electrometer, the solid detector and array phantom. The solid detectors were constructed using commercially diodes for the assessment of quality assurance in radiotherapy. And it was used for the point dose measuring and field size scanning. The semiconductor detector and ion chamber were positioned at a dmax, 5 cm, 10 cm, 20 cm depth and its specific ratio was determined using a scanning data. Wedge angles in fixed and virtual type are compared with measurements in water phantom and it is shown that the wedge angle 15$^{\circ}$, 30$^{\circ}$, 45$^{\circ}$were agree within 1$^{\circ}$ degree in 6, 10 MV photon beams. In PDD and beam flatness, experimental multi-channel disimetry system was capable of reproduceing the measured values usually to within $\pm$2.1% the statistical uncertainties of the data. It was used to describe dosimetric characteristics of virtual wedge in clinical photon beams. Also we was evaluate optimal use of the virtual wedge and improve the quality factor of the experimental multi-channel dosimetry system for virtual wedge.

Background: As the prevalence of nontuberculous mycobacteriosis has been increasing rapidly, there has been recent advance in diagnostic methods and drug therapies for disease. Although the incidence of pulmonary disease caused by nontuberculous mycobacteria(NTM) has been increasing in Korea since 1990, detailed clinical description about the disease were very few. In this study we described the clinical manifestations, radiologic findings, and therapeutic outcomes of nontuberculous mycobacterial pulmonary disease. Methods: Medical records and radiologic findings were retrospectively reviewed in 27 patients who were fulfilled the diagnostic criteria of ATS guideline for NTM pulmonary disease between January of 1990 and August of 1998 in Seoul National University Hospital(SNUH). Results: Of the 27 patients, 15 were male. The mean age was 51.5 yr($\pm$11.9). Twenty patients(74.1%) had preexisting pulmonary diseases. Among them, 19 patients had previous pulmonary tuberculosis. Sixteen patients(59.2%) had cavitary lesions and the majority showed slow progression over 1 yr during follow up period on radiography. Susceptibility test to standard antituberculous drugs showed 100% resistance to INH, 72.2% to RMP, 81.5% to EMB, 92.6% to PZA. The average resistance rate to 2nd-line antituberculous drugs was 66.1%. Among twenty-one patients(77.8%) who received drug therapy over 6 months, 11 subjects were improved and 10 subjects were aggravated. Of six subjects(22.2%) without therapy, 5 patients were aggravated. Presence of cavity and less than 3 sensitive drugs in the regimen were indicators for adverse outcome. Conclusion : The nontuberculous mycobacterial pulmonary diseases in our hospital developed predominantly in older patients with preexistent pulmonary disease. The results of antituberculous drug therapy has been frustrating and disappointing. To improve treatment response, different susceptibility tests and drug regimens for different species of NTM should be performed. Also, diagnostic and therapeutic guidelines of Korea should be made in the recent future.

Objective: To compare COH characteristics and IVF outcomes among IVF-ET patients who were treated with various therapeutic modalities for ovarian endometriomas and to propose effective pre-cyclic therapeutic modalities to improve IVF-ET outcomes in the patients with ovarian endometriomas. Methods: All cases that had undergone IVF-ET after laparoscopy between January 1997 to August 2003 were reviewed. Forty-eight patients with tubal factor were assigned to Group I. Twenty seven, 22 and 38 patients diagnosed as severe pelvic adhesion with ovarian endometriomas by laparoscopy received only medical therapy (Group II), cyst aspiration (Group III), and sclerotherapy (Group IV), respectively. Laparoscopic cystectomy was performed in 20 patients (Group V). Resistance index was measured on day administering hCG. Results: As compared with Group I, in Group II resistance index increased (p<0.05) but number of oocytes, good-quality oocyte ratio (mature and intermediate oocytes/total retrieval oocytes), fertilization rate, and embryo development rate decreased (p<0.05). In Group III fertilization rate and embryo development rate decreased (p<0.05). There was no difference between Group IV and Group I in all parameters except basal FSH which increased (p<0.05). In Group V basal FSH, and resistance increased (p<0.05) and number of oocytes and good-quality oocytes ratio decreased (p<0.05). Conclusion: Sclerotherapy is an effective therapeutic option which can be done prior to IVF-ET cycles in the patients with ovarian endometriomas. Further studies on a large scale are necessary to confirm these data.

There needs disease-predictable signs in order to enable preventive diagnosis and therapy. Then traditional Chinese medicine applies various medical diagnostic equipments used in western medicine to diagnosing sub-healthy state. But such data are not originated from inherent oriental medicine, and not obtained easily in ordinary clinical practice. This paper is to provide synopsis of the ante-disease diagno-therapeutics partly and to show predictable data based on the facial shapes and signs, especially of gall bladder's versus bladder's body and masculine versus feminine shape. Ante-disease means not only the complete healthy state, but also the state unseen any symptoms in macrographically in the course of outbreak of disease. It contains two stages, first one is the former state of disease and second one is untransmitted state of disease. The patterns of ante-disease consist of latent disease, pre-disease, transmission type like senescent syndrome, abnormal reactive syndrome(變證), syndrome of transmission and transmutation. The classification with gall bladder and bladder type manifests the differences of shape, color and size of each organ in comparison of the universal and standard figures of the human being. On the other hand, the classification with masculine and feminine shape contrasts the innate sexual difference and the shape, characteristics originated from in itself. These two classification theories have their own pathologic types and syndrome types with each disease so that disease-predictable data can be constructed based on such a relationship. In addition, this diagnostic method by facial shapes and signs is able to be applied to whole stages from prenatal to present state of disease even if the cause and inducement are not clear. Ante-disease diagno-theraputic system by Gall Bladder's versus Bladder's Body and Masculine versus Feminine Shape is getting more important in the chronic and internal disease in comparison of the acute and traumatic disease. So this study is able to make up for the limit of diagnosis on ante-disease in the field of oriental medicine clinic.

Objective: To report the clinical and radiological characteristics of patients with underlying B-cell lymphoma and coronavirus disease 2019 (COVID-19) showing migratory airspace opacities on serial chest computed tomography (CT) with persistent COVID-19 symptoms. Materials and Methods: From January 2020 to June 2022, of the 56 patients with underlying hematologic malignancy who had undergone chest CT more than once at our hospital after acquiring COVID-19, seven adult patients (5 female; age range, 37-71 years; median age, 45 years) who showed migratory airspace opacities on chest CT were selected for the analysis of clinical and CT features. Results: All patients had been diagnosed with B-cell lymphoma (three diffuse large B-cell lymphoma and four follicular lymphoma) and had received B-cell depleting chemotherapy, including rituximab, within three months prior to COVID-19 diagnosis. The patients underwent a median of 3 CT scans during the follow-up period (median 124 days). All patients showed multifocal patchy peripheral ground glass opacities (GGOs) with basal predominance in the baseline CTs. In all patients, follow-up CTs demonstrated clearing of previous airspace opacities with the development of new peripheral and peribronchial GGO and consolidation in different locations. Throughout the follow-up period, all patients demonstrated prolonged COVID-19 symptoms accompanied by positive polymerase chain reaction results from nasopharyngeal swabs, with cycle threshold values of less than 25. Conclusion: COVID-19 patients with B-cell lymphoma who had received B-cell depleting therapy and are experiencing prolonged SARS-CoV-2 infection and persistent symptoms may demonstrate migratory airspace opacities on serial CT, which could be interpreted as ongoing COVID-19 pneumonia.

The purpose of this study was to describe the perceived burden of the terminally III patients's caregiver and to analyze relationship between the perceived burden and the various demographics, illness characteristics, family relationships, and economic factor of the family & patients. The sample of 132 caregivers who care for the terminally III patients Kyung-Gi province, Seoul, Korea. The period of this study was from August to September, 2002. The perceived burden of the family caregiver was measured by the burden scale(20 items, 4 point scale) developed by Montgomery et al. (1985). The Data was analyzed using SAS-program by t-test and ANOVA. The results were as follows; 1. The mean of the family caregiver's burden score was 3.02. The score showed that caregivers perceive severe the level of burden. The hight items of the family caregiver's burden were' I feel it is painful to watch patient's diseases'(3.77). 'I feel afraid for what the future holds for my patients'(3.66), 'I feel it reduced to amount of privacy time'(3.64). 2. The caregiver's burden was significantly related to patient's gender(F=3.17, p= 0.0020), patient's job(F=2.49, p=0.0476), caregiver's age(F=4.29, p=0.0030), and caregiver's job(F=2.49, p=0.0476). 3. The caregiver's burden according to illness characteristics showed no significant difference. 4. The caregiver's burden was significantly associated with patient's family relationship (F=4.05, p=0.0041), patient's care mean period in a day(F=47.18,

In this paper, we propose the development of nitrogen cooling equipment for personalized local area. The proposed equipment consists of a cold air supply module, a body, and nitrogen injection with the following characteristics. First, it automatically controls the amount and time of cold air supply by utilizing information measuring skin temperature with volumetric temperature sensors, so it can have a competitive edge in function by ensuring complete safety. Second, if the distance measuring sensor is applied to the skin for more than a certain distance, it can block the cold air or control the discharge of nitrogen in conjunction with the control GUI to improve the efficiency of higher cooling therapy while providing safe management. Third, by installing a control module that can control the supply of nitrogen, the cost of maintenance can be minimized by minimizing the loss of nitrogen. Experiments at an external testing agency to evaluate the performance of the proposed equipment showed that the accuracy of the temperature sensor was measured in the range of ±3.8%, which is lower than the world's highest level(±5%), with a range of 110℃ to -160℃ similar to the world's highest level. Distance accuracy was measured in the range of ±3.0%, lower than the world's highest level(±5%), and weight accuracy in the range of ±0.1%, lower than the world's highest level(±5%). In addition, emission control was measured in four stages, higher than the world's highest level(stage 1) and nitrogen use was measured at 0.8L/min below the world's highest(6L/min). Therefore, the effectiveness of the methods proposed in this paper was demonstrated because they produced the same results as the world's highest levels.

From March, 1983 to March, 1987, 16 patients with esophageal steno-obstruction due to nonesophageal tumors were treated in the Division of Therapeutic Radiology, Kangnam St. Mary's Hospital, Catholic University Medical College. The patient characteristics, effect of radiotherapy (XRT) on esophageal steno-obstruction and survival were evaluated. The most common primary tumor was lung cancer (14/16) and the middle third of the esophagus was most frequently involved (14/16). Improved clinical response was observed in $80\%$ of the patients who finished the planned courses of XRT. The mean radiation dose evoking the improvement of dysphagia was 2,993 cGy given over a period of 3 to 4 weeks. The Kaplan-Meier estimates of survival at 15 and 30 weeks of follow-up were $60\%$ and $46\%$, respectively. In the completed group who finished the whole planned courses of XRT, survival rates were $77\%\;and\;51\%$, respectively. Four patients were alive over 90 weeks with normal passage of food.
