As the incidence of dermographism in our urticaria clinie is quite high comparing data in other country, we have tried to survey the incidence of ermographism in the general population of Korea using a dermographic tester designed by other author. Total 8g7 healthy persons were included in this study from March J98$ to .December 1983. The study result was summarized as follows, 1. Male to female ratio was 2. 5: 1 and the peak age of the subjects was third(47 8%), fourth and fith decades in ecreasing order, The overall incidence of dermographisrn from the pressure of 48ppg/cm was 4.4% and there were no significa.nt difference in the incidences between male(4, 2%) and female(4 7%) (p>0. 1), and between the different age groups(p>0 l)

Three cases of hydatidiform mole with a coexisting fetus are described. In two cases, flow cytometric analysis of nuclear DNA content from paraffin-embedded, molar tissues and normal-appearing placental tissues showed diploid pattern. One case had karyotypes of 46, XX both in fetal skin fibroblasts and in molar tissues. Microscopically, the villi showed diffuse hydropic swelling with circumferential trophoblastic proliferations and consistent with the diagnosis of complete mole. Two patient had persistent gestational trophoblastic neoplasia on the follow-up. Therefore, in cases of hydatidiform mole with a coexisting fetus, dizygotic twin pregnancies composed of a normal pregnancy from one ovum and a complete mole pregnancy from the other ovum must be considered and the patients should be followed with serum beta-hCG measurements.

The purpose of this study was to investigate the effects of green tea ingestion on hepatocarcinogenesis before and after its initiation. Male Sprague-Dawley rats were fed an AIN76A diet with or without green tea. Initiation was induced by a single dose (200 mg/kg) of diethylnitrosamine at week 4 and 0.02% (w/w) 2-acetylaminofluorene was supplied in the diets. The control group had free access to water for 13 weeks (CTR13). Tea infusion was provided from the beginning of the experiment for 13 weeks (PRE13) or from the post-initiation stage until week 13 (POST13). Three other groups (CTR24, PRE24 and POST24) were added to examine the longer-term effects (24 weeks) with the same experimental design. The percentage area of liver sections that were positive for hepatic placental glutathione S-transferase (GST-P), which was used as a marker of preneoplastic lesions, was smaller in PRE13 (20.2 +/- 5.0%, mean +/- SD) and POST13 (26.0 +/- 4.8%) than in CTR13 (33.2 +/- 5.8%, p<0.05). Over the longer period, the GST-P lesions were significantly smaller for both PRE24 and POST24 (21.6 +/- 8.5% and 22.2 +/- 4.0%, respectively) than for CTR24 (28.6 +/- 5.1%, p<0.05), but there was no significant difference between PRE24 and POST24. The liver content of thiobarbituric acid reactive substances was significantly lower in the tea groups than in the controls (p<0.05). However, no significant differences were observed among groups of GST activity. The results show that tea consumption exhibits a stronger short-term initiation-inhibiting ability in liver carcinogenesis, but over a longer period, the preventive effects of green tea ingestion do not differ in post- and pre-initiation.

PURPOSE: To investigate changes in Quality of life (QOL) and related factors in patients with thyroid cancer undergoing Radioactive Iodine remnant ablation (RAI). METHODS: Data were collected longitudinally 3 times for 6 months (2 weeks post-surgery, post RAI, 3 months post RAI) in a hospital located in Seoul. Questionnaires were used to measure levels of physical symptoms, anxiety, depression, and QOL. Ninety-eight patients with thyroid cancer who had RAI were included in the analysis. Data were analyzed using SPSS (18.0). RESULTS: Findings for the three data collection times respectfully were: mean scores for physical symptoms, 0.53, 1.21 and 0.62, patients with depression, 47%, 36.7% and 37.7%, patients with anxiety, 18.4%, 19.4% and 20.4%, mean scores for QOL, 7.06, 7.01 and 7.28. QOL score was highest 3 months post RAI (p=.031). In the stepwise multiple regression analysis, depression and fatigue were predicting factors for low QOL at all data collection times. Dysponia was a predicting factor for low QOL post RAI and 3 months post RAI. CONCLUSION: To increase QOL, it is necessary to provide information in advance regarding physical & psychological symptoms and to develop nursing intervention programs to decrease depression and fatigue.

PURPOSE: This study was conducted to investigate the effect of music therapy as auditory stimulus on the heart rate and behavioral state of premature infants. METHOD: The study design was a non-equivalent control group pretest-posttest design. Forty premature infants who were admitted at NICU were selected and assigned to two groups, experimental and control. Data were collected from April 20 to July 31, 2003 and analysed using Wilcoxon rank sum test and ANCOVA. Infants in experimental group were given music therapy for 20 minutes daily in 7 days at the average level of 56dB. RESULTS: The first hypothesis that 'Infants in the experimental group will be lower in heart rate than those in the control group' was rejected(F= .05, p= .816). The 2nd hypothesis that 'Infants in the experimental group will be lower in behavioral state score than those in the control group, was supported(F=7.40, p= .010). CONCLUSION: The music therapy in this study was an effective nursing intervention in decreasing the heart rate and behavioral state score of premature infants.

PURPOSE: We performed dynamic MR imaging using GdDTPA to find characteristic enhancement pattern of hepatic hemangioma distinguishing from hepatocellular carcinoma. METHODS AND MATERIALS: 28 hepatic hemangiomas and 10 hepatocellular carcinomas were evaluated. Serial dynamic scans after Gd-DTPA(0.1mmol/kg) intravenous injection were obtained by using 0.5T machine and analyzed contrast-to-noise ratio(CNR) of the lesion and enhancement pattern on each scan. RESULTS: Hepatic hemangiomas had positive CNR from 1-2 minute images, and revealed typical "fill-in phenomenon" on early phase with prolonged enhancement in 26 cases(92.8%), and early homogeneous enhancement with isointensity on delayed phase in 2 cases(7.2%) of small hemangiome~ Hepatocellular carcinomas revealed inhomogeneous enhancement with hypointensity on delayed phase in 10 cases(100%) and 3 cases (30%) of capsular enhancement. CONCLUSION: Hepatic hemangioma can be easily distinguished from hepatocellular carcinoma by using Gd DTPA enhanced dynamic MR imaging according to its typical enhancement pattern of "fill-in phenomenon" and prolonged enhancement.

Purpose: This study examined the impact of a virtual reality intervention program based on psychological needs on behavioral and psychological symptoms, apathy, and quality of life (QOL) in patients with dementia or mild cognitive impairment living in nursing facilities. Methods: This study is nonequivalent control group pretest-posttest design of quasi-experimental study. The study collected data from November 18, 2020 to July 24, 2021 from patients with dementia or mild cognitive impairment (30 in the experimental group and 30 in the control group) at three nursing facilities in G city using self-reporting and caregiver-informant reporting methods. The analysis employed the chi-square test, Fisher’s exact test, paired t-test, independent t-test, Wilcoxon signed rank test, Mann–Whitney U, repeated measures ANOVA, GEE, using SPSS/WIN 27.0. Results: The severity of behavioral and psychological symptoms (Wald χ2 = 2.68, p = .102) and the care burden of caregivers (Wald χ2 = 1.72, p = .190) were not significant and was no significant time and group interaction effect (Wald χ2 = 0.63, p = .426, Wald χ2 = 0.52, p =. 471). The difference in apathy and QOL score were statistically significant for the group-time interaction (F = 43.65, p < .001; F = 4.35, p= .041). Conclusion The virtual reality intervention program of this study shows a positive effect on the apathy reduction and QOL of patients with dementia or mild cognitive impairment residing in nursing facilities.

OBJECTIVES: This study analyzes the effect of role stress on turnover and examines the mediating effects of organizational, career, and job commitment. METHODS: This study involved a questionnaire survey on socio-demographic characteristics, working environment, role stress, commitment, and turnover. This was administered to 272 clinical dental hygienists from February 1, 2014, to February 28, 2014, and data were analyzed using t-test, one-way ANOVA, Pearson correlation analysis, and hierarchical multiple regression. RESULTS: Turnover among dental hygienists increased when their role stress was high and the latter was significantly correlated with organizational, career, and job commitment. In the relationship between role stress and turnover, organizational and career commitment worked as the mediating factors with organizational commitment showing the biggest effect. CONCLUSIONS: In order to reduce role stress, the causes of role conflict and role overload should be systematically monitored. Improvement of the wage and working system along with expansion of specific tasks of dental hygienists to enhance their organizational and career commitment is required.
