PURPOSE: The purpose of this research was to provide baseline data by utilizing solutions to health problems caused by work-related stress and to examine a way of treatment by comparing and analyzing how the stresses link to fatigue and quality of researchers' life. METHODS: A survey was conducted with 50 researchers working for in H research institute in Daejeon Metropolitan City from April 10th to May 10th, 2012 to examine the correlation of work stress, fatigue and quality of life. The data were analyzed using the Kruskal-Wallis test to look into examine the difference in work stress, fatigue, and quality of life. Also, the correlation of work stress, fatigue and quality of life was measured through by the Pearson correlation coefficient. The data collected through the questionnaires was were analyzed by SPSS 21.0 based on the significant level with a p-value, 0.05. RESULTS: The results showed that fatigue was caused by work stresses in researchers and quality of life was ranked in a relatively low level. Correlation of work stresses, quality of life and fatigue and work stresses against mental health index was negative and fatigue against physical index was also negative. CONCLUSION: It is necessary to maintain more detailed provisions in order to improve mental health and stress level of researchers. Moreover, systematic, in-depth evaluation should be done to reduce researcher's work-related stress and fatigue. In addition, stress management and prevention program should be implemented for these researchers.

Subacute cutaneous lupus erythematosus is a recently recognized distinct subset of lupus erythematosus, having characteristics of clinical, pathologic, serologic, irnrnunologic features. We present a case of subacute cutaneous lupus erythematosus in a 29-year-old woman with symmetric, superficial, nonscarring papulosquamous lesion on the face, scalp, and the extensor surface of the upper extremities. She has a mild systemic illness of musculoskeletal complaints. Serologic abnormalities of the patients are positive rheumatoid factor and anti-Ro antibody test, but fluorescent antinuclear antibody test is negative, which is done by the conventional methods uaing rodent tissue for the substrate. The histopathologic finding of the lesion show the sarne general pattern of the cutaneous lupus erythematosus, and lupus band test is positive.

In order to extract useful tumor cell-specific information. DNA contents and other morphological parameters were measured by image analysis. Single cell preparation was made from archived paraffin blocks of 14 cases of bronchogenic squamous cell carcinoma, poorly differentiated, by protease treatment. The cells were Feulgen stained, and DNA content, area, perimeter, and major axis of the tumor cell nuclei were measured. Inflammatory lymphocytes concurrent with the tumor cells were used as an internal standard. DNA ploidies of the lymphocytes and 2C tumor cells showed simple peaks with Gaussian distribution and mean coefficients of variation of 10% and 14% respectively. By the location and proportion of the tumor cells other than 2C cells, DNA ploidies could be classified into diploidy(1 case), polyploidy(2 cases), and aneuploidy(11 cases). The mean proportion of DNA aneuploidal tumor cells relative to the total tumor cells was 82.8%. In 8 cases, nuclear areas showed more or less overlapped distribution, whereas DNA contents showed discrete peaks. THes results suggest that many bronchogenic squamous cell carcinomas, poorly differentiated, have DNA aneuploidy and high proportion of aneuploidal cells, and that nuclear size and DNA content are more or less independent parameters.

BACKGROUND:Acute vestibular neuronitis is the disease of which the etiology and pathophysiology are largely unknown . But the viral infection and ischemia of the labyrinth and the vestibular nerve are considered as general etiology. This study was performed to support the viral infection rather than the ischemic theory. MATERIALS & METHODS:We studied seventy years old female patient who showed painful vesicles on left auricle and vertigo with spontaneous nystagmus to the right side. We performed physical examination, serologic test, ENG test, pure tone audiogram, brain magnetic resonance imaging and polymerase chain reaction. RESULTS:We found small vesicles and vascular injection in left EAC, herpes zoster IgG positive, spontaneous right beating in electronystagmograpy, 54% left canal paresis in Caloric test , decreasing left side Tc in velocity step rotatory test, decresed gain, deviation to left in symmetry and phase lead in sinusoidal harmonic acceleration test, normal range hearing in pure tone audiogram, microangiopathy on cortex in brain MRI and negative PCR. CONCLUSION:This case supports viral infection etiology rather than ischemia in vestibular neuritis. But more studies to find the etiology of vestibular neuronitis are required.

OBJECTIVES: Panic disorder is a chronic condition that may carry significant negative impact on the quality of life in patients. However, the association between quality of life in panic patients and their clinical characteristics has not been investigated. Aim of this study is to compare quality of life in panic patients and healthy controls by using WHO Quality of Life(QOL) Scale that evaluates the domains of physical health, psychological health, social relationship and environment. Additionally, relationship between clinical factors in patients with panic disorders and their quality of life were explored. METHOD: 64 patients with panic disorder and 27 healthy controls were recruited in this study and WHO QOL Scales were completed. Total scores and scores of domains of WHO QOL Scale in two groups were compared. Correlation analysis and multiple regression analysis were performed to examine the relationship between quality of life and the clinical characteristics in patients with panic disorder. RESULTS: Total scores and scores of all domains except environmental domain of WHO QOL scale in patients with panic disorder were decreased compared to those in healthy controls. Clinical characteristics including the severity of agoraphobia and depression, number of symptoms during panic attacks and the frequency of panic attacks showed significant correlation with quality of life in general and most of subscales of QOL. Multiple regression revealed that the severity of depression, the number of symptoms during panic attacks and the severity of agoraphobia in the presence of accompanied persons were factors directly affecting the quality of life in the patients with panic disorder. CONCLUSION: Quality of life in patients with panic disorder was poorer than that of healthy controls. The severity of depression, the number of symptoms during panic attacks and the severity of agoraphobia in the presence of accompany were related to the quality of life in the patients with panic disorder.

Thirty cases of rhabdomyosarcoma in patients under the age of 15 years were reviewed retrospectively to find out characteristics of histologic subtypes related to prognosis. Histologic diagnosis were embryonal in 21(70%), alveolar in 7(23%) and mixed type in 2(7%). Cellular anaplasia was noted in 6 cases. Round to polygonal cells with abundant eosinophilic cytoplasmic rim or globules were most characteristic cytologic feature or rhabdomyosarcomas, being followed by myofibrils. Myxoid and edematous stroma in embryonal type and alveolar pattern in alveolar type wee nost characteristic growth pattern. Immunohistochemically, tumors were positive for desmin, actin and myoglobin in 97%, 27%, and 40%, respectively. Consequently, characteristic cytologic features are important to differentiate rhabdomyosarcomas form other kinds of small round cell tumor and growth pattern is more critical in categorizing histologic subtypes. Desmin is far more useful than actin or myoglobin in the diagnosis of rhabdomyosarcoma.

Biological behavior of malignant tumors has been assessed by morphological grading, clinical staging, and estimating other tumor markers. Recently DNA ploidy measured by flow cytometry and image analyser has been suggested as an additional useful indicator of the tumor behavior. In order to extract useful tumor cell-specific information in ovarian mucinous tumors, DNA contents and other morphologic parameters were measured by image analysis and DNA ploidy was also measured by flow cytometry. In all cases of cystadenoma, DNA diploidies were observed. In borderline malignancy, DNA diploidies were chiefly observed except one case of polyploidy. In true malignancy, DNA aneuploidies were observed except one case of polyploidy and two cases of diploidies by image analysis, and except four cases of diploides and one cas of polyploidy by flow cytometry. The statistical significance were observed in DNA ploidy pattern by image analysis. In nuclear areas, perimeters and major axis, statistical significance were not observed. These results suggest that DNA ploidy pattern are more or less independent parameter as an additional useful indicator of the histological grade of malignancy and that image analysis are better than flow cytometry in detecting DNA aneuploidy.
