A 11-year-old, female Russian Blue cat was presented with anorexia, vomiting, and diarrhea lasting for 3 days. Abdominal ultrasonography revealed a hypoechoic, non-circumferential, and eccentrically formed intestinal loop with altered wall layering and thickening of the tunica muscularis. After surgical resection, histopathologic examination confirmed an infiltrative, round-cell neoplasm composed of sheets and cords of neoplastic mast cells within a fibrotic, edematous stroma. The cat was alive and healthy 6 months after surgery. To the best of our knowledge, this is the first reported case of an intestinal mast cell tumor in a Russian Blue cat in South Korea.

Pilot's complacency and confidence have been implicated as a contributing factors in numerous aviation accidents and incidents. It is related to ones belief that one is capable of performing in a certain manner to attain certain goals which is called 'Self-Efficacy' as a psychological concept. The purpose of this study was to construct and validate pilot's self-efficacy scale. This study examined the necessity of pilot efficacy in terms of pilot's confidence and complacency, and considered what is components and processes of pilot self-efficacy through the reference to literature. This Study newly defined 'pilot-efficacy' as vocational self-efficacy in flight operation field. Based on literature review and advisory group's review, there made 3 factors of Pilot-Efficacy:Flight-Efficacy, Relational/Communication Efficacy, and physical and psychological Stress-Coping Efficacy. Preliminary pilot-efficacy scale was administered to pilot group analysis Item analysis was conducted to select appropriate items and common factor analysis was done to identify the subcomponents of pilot efficacy scale. In result, 35 items were selected. The measurement of pilot efficacy for individual makes it possible to predict pilots' behavior when they make decision both normal and non-normal situation. This scale is expected to be not only predictable but also useful to enhance aviation safety. Finally, suggestion for following studies were discussed.

Tetanus is a neurologic disease which features the muscle spasm as the hallmark. It is an infectious disease with high mortality rate triggered by tetanospasmin produced by Clostridium tetani. This report concerns incidence of tetanus consequent to oriental medical care such as acupuncture and moxibustion. Although the tetanus occurrence has shown a remarkable decline since nationwide vaccinations in some of the developed countries, including Korea, it still remains to be an important issue, to be dealt within Korea, as the majority of the patients are old aged and Korean population is rapidly becoming an aging society. Furthermore, since more elders are coming to rely on Oriental medicine in Korea, the Korean elders are at a higher risk than elsewhere. The lack of medical experiences, including those in oriental medical field, has been hindering early diagnosis of Tetanus. This study aims to encourage rapid and accurate decisions in diagnosis and treatment through reviewing symptoms particularly specific to tetanus, and also to arouse attention to the riskiness of invasive procedures involving skin puncture.

Chronic hepatitis associated with the idiopathic hypereosinophilic syndrome has been very rarely reported worldwide. Recently, we experienced a case of chronic hepatitis with piecemeal necrosis as the clinical feature of the idiopathic hypereosinophilic syndrome. The patient was a 49-year-old woman who complained of a mild fever, nausea, vomiting, and pain in the right upper quadrant. The eosinophil count of peripheral blood increased up to 14,020/microliter (64% of WBC). Liver biopsy specimen showed severe porto-periportal inflammation with marked eosinophilic infiltration and ballooning degeneration of hepatocytes. Corticosteroid therapy significantly normalized the eosinophil count of peripheral blood.

Cardiac arrhythmia which was observed during 5 years and 10 months from September 1975 to June 1981 on 11, 273 ECG records of the pediatric patients were analysed. Simple sinus arrhythmia and bundle branch blocks were excluded from this study. 602 cases of arrhythmia were seen among the 11,273 cases(5.3%). The types of arrhythmia in the order of frequency are: A-V block ectopic beat, multifocal rhythm, paroxysmal tachycardia, A-V junctional rhythm. A-V dissocation, atrial fibrillation, ventricular fibrillation and escape beat. The main underlying causes of the serious cardiac arrhythmia were congenital heart disease, open heart surgery, rhematic heart disease, cardiomyopathy and myocarditis.

PURPOSE: The purposes of this study were to explain the phenomena of hot flashes in climacteric women by using Mexameter, Skin Thermometer, Corneometer, and Laser Doppler Perfusion Imager (LDPI) objectively and to identify the interrelation between the subjective and objective measurements of hot flashes by comparing the two as reported in retrospective questionnaires. METHODS: The participants were one hundred women (45-60 yr) who were not currently on hormone therapy, and had reached hot flash scores of 10 or higher. Hot flashes were measured in a temperature and humidity controlled room for 7 hr from 10 am to 5 pm. Hot flashes were measured subjectively and recorded via the Hot Flash Diary Report. When participants felt the hot flashes, they were measured objectively by Mexameter, Skin Thermometer, Corneometer, and LDPI. RESULTS: The frequency of hot flashes in participants ranged from 1 to 7 times. When hot flashes occurred in participants, the erythema, skin temperature, skin hydration, and blood perfusion showed statistically significant changes in all measurements. But, the subjective and objective measurements of hot flashes showed only weak correlations. CONCLUSION: Results indicate a need for future research with subjective and objective measuring instruments chosen depending variations identified for the study.
