This study was done for the purpose of analysing the relationship between menopausal syndrome and depression in the pre and post menopausal women's group. Data were collected by a questionnaire from November, 1995 to December, 1996. The subject were 244 midlife women(94 subjects were in pre-menopausal period, 150 subject were in post-menopausal period). The instruments used for this study were the menopausal syndrome scale by Neugarton and depression scale by Zung. Data were analyzed with the SPSS/PC using frequency, t-test, and Pearson correlation coefficients. The results of this study were as follows ; 1. The most serious menopausal symptom in the midlife women was 'back pain and joint pain'. 2. The item of 'Hot flush'(t=-2.78, p<0.01), 'sweating'(t=-2.31, p<0.05) and 'nervousness'(t=-2.13, p<0.05) as menopausal syndromes were statistically significant in the two groups ; Post menopausal group were higher then premenopausal group. 3. Postmenopausal group were a little higher then premenopausal group as depression level. It was none statistically significant in the two groups. 4. The relationship between menopausal syndromes and the level of depression was statistically significant in the group of post-menopausal group(r=0.2083, p<0.01).

During investigating of shiitake mushroom competitors, 289 isolates of Trichoderma spp. were collected from shiitake mushroom farms in different districts and the Forest Mushroom Research Center of Korea, among which 29 representative strains were selected. Based on the DNA sequences of the rpb2 and tef1 genes and the ITS rDNA, and their morphological characteristics, they were identified as T. atroviride, T. citrinoviride, T. harzianum, T. longibrachiatum, and two undescribed species, Trichoderma spp. 1 and 2, which are considered to be the candidate of new species. Competition tests between Lentinula edodes (Sanjo302) and the Trichoderma species indicated that the six species of Trichoderma were significantly different from each other in terms of their ability to invade the mycelial blocks of shiitake. In both of dual cultures on potato dextrose agar and sawdust media, Trichoderma spp. 1 and 2 strongly invaded the mycelial blocks of shiitake. Our results suggest that the two Trichoderma species may cause potentially serious economic losses in shiitake cultivation of Korea.

The present study was planned to evaluate the bioequivalence of two commercial formulations of enrofloxacin, which have been marketed as 10% injectable solution after intramuscular administration at a single dose of 2.5 mg/kg body weight to 12 clinically healthy goats The study was carried out on the basis of crossover design. The two formulations were: Baytril as a reference product and Spectrama Vet as a test product. The plasma concentrations of enrofloxacin were measured by high performance liquid chromatography (HPLC) with UV detector. The pharmacokinetics of that data was performed using non-compartmental analysis. The maximum plasma concentration ($C_{max}$), time to reach peak concentration ($T_{max}$), area under concentration-time curve (AUC), elimination half-life ($t_{0.5el}$) were 1.14 and $1.05{\mu}g/mL$, 0.79 and 0.83 h, 5.70 and $5.79{\mu}g.h/mL$, 5.19 and 5.39 h for Baytril and Spectrama Vet, respectively. The 90% confidence interval for the mean ratio of $T_{max}$, $C_{max}$ and AUC were 94.72-116.2, 87.88-97.16 and 86.44-118.72%, respectively. These values falls within the European Medicines Agency bioequivalence acceptance range of 80-125% for both $T_{max}$ and AUC and between 75-133% for $C_{max}$. In conclusion, Spectrama-Vet is bioequivalent to Baytril and both products can be used as interchangeable drug in veterinary medicine practice.

This study examined the relationship between aminotransferase and DITI in the diagnosis of Liver Qi stagnation. An analysis was performed on the thermographic findings of 17 subjects with abnormally high aminotransferase value and 26 with no problem in blood sample at the Kangnam Korean Hospital, KyungHee University, Seoul, Korea, from March 2003 to May 2003. The body temperature was assessed by DITI thermographic measurements were performed on Rt. and Lt. subcostal area. Value of ${\delta}T$ and absolute value of ${\delta}T$ were tested by Mann-whitney U test. The absolute value of ${\delta}T$ was statistically significant(P<0.00). The ${\delta}T$ was also significant(P<0.01) and the temperature of Rt. area was higher than that of Lt. area. It is believed that DITI may be a favorable alternative to the diagnosis of Liver Qi stagnation.

PURPOSE. The aim of the present study was to determine the degree of conversion of light- and dual-cured resin cements used in the cementation of all-ceramic restorations under different thicknesses of translucent (T) and high-translucent (HT) polymer-infiltrated ceramic-network (PICN) material. MATERIALS AND METHODS. T and HT PICN blocks were prepared at 0.5, 1.0, 1.5, and 2.0 mm thicknesses (n=80). Resin cement samples were prepared with a diameter of 6 mm and a thickness of 100 ㎛. Light-cured resin cement was polymerized for 30 seconds, and dual-cure resin cement was polymerized for 20 seconds (n=180). Fourier transform infrared spectroscopy (FTIR) was used for degree of conversion measurements. The obtained data were analyzed with ANOVA and Tukey HSD, and independent t-test. RESULTS. As a result of FTIR analysis, the degree of conversion of the light-cured resin cement prepared under 1.5- and 2.0-mm-thick T and HT ceramics was found to be lower than that of the control group. Regarding the degree of conversion of the dual-cured resin cement group, there was no significant difference from the control group. CONCLUSION. Within the limitation of present study, it can be concluded that using of dual cure resin cement can be suggested for cementation of PICN material, especially for thicknesses of 1.5 mm and above.

Purpose: This study aimed to determine the effect of knowledge and attitudes of preventive behavior plans (PBPs) on Zika virus infection among university students. Methods: Participants included 130 students from H University in Korea. Electronic self-reported questionnaires were used to collect data. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and regression analysis with SPSS/WIN 23.0. Results: The mean percentile score for knowledge was 35.52±20.63. The mean scores for attitudes and PBPs were 3.31±0.47 and 3.07±0.72, respectively, out of 5 points. Knowledge (t=-5.79, p<.001), attitudes (t=-3.17, p=.002), and PBPs (t=-2.67, p=.009) differed significantly with respect to awareness concerning Zika virus infection. The factor 'attitudes' significantly affected PBPs, with an R² value of 12.0% (β=.27, p<.001). Conclusion: Developing a correct attitude toward Zika virus infection may be key to improving preventive behaviors. Health education messages should be tailored to increase preventive behaviors against Zika virus infection. Nursing educators will benefit from partnerships with health educators and by using internet media to speed up the dissemination of Zika virus information.

Purpose: This study aimed to develop and evaluate an integrated management program to enhance self-efficacy, compliance with sick-role behaviors, symptom management, and biomarker indication in hemodialysis patients. Methods: The integrated management program was developed through a systematic review of literature, analysis of relevant online data, and expert validation. It comprised 480 min of video-based education delivered eight times over four weeks, supplemented by weekly phone consultations and text message support from a nurse. To evaluate the program's effectiveness, it was administered to 44 patients with hemodialysis in a single group in a pre-post test experimental study. Changes in self-efficacy, sick-role behavior compliance, dialysis symptom index, and biomarkers were assessed. Results: The program yielded statistically significant improvements in self-efficacy (t=-7.13, p<.001), sick-role behavioral compliance (t=-7.35, p<.001), dialysis symptom index (t=4.32, p<.001), and blood urea nitrogen levels (t=2.55, p=.014) among the participants. Conclusion: The integrated management program is an effective intervention for improving hemodialysis patients' self-efficacy, compliance with sick-role behaviors, and experience of symptoms. Additionally, it is considered an intervention with high clinical applicability and efficiency through video reproducibility.

Purpose: This study aimed to assess the knowledge level of first-time mothers regarding digestive health issues in infancy and to examine the utilization of healthcare facilities for such problems. Methods: Data from 119 first-time mothers of infants under 6 months of age were analyzed. Descriptive statistics, t-test, and one-way analysis of variance (ANO-VA) were conducted using the SPSS software. Results: The average correct response rate for first-time mothers' knowledge of digestive health problems in infancy was 61.9%. The highest correct response rate was observed for infantile colic, while diarrhea had the lowest. Less than 50% of mothers received education on infant digestive health problems across all categories. Among digestive health problems in infancy, diarrhea exhibited the highest rate of healthcare utilization, whereas infantile colic had the lowest. First-time mothers' knowledge of digestive health problems in infancy varied based on maternal age (t=-3.66, p<.001), education level (t=-2.26, p=.026), and planned pregnancy (t=3.24, p=.002). Moreover, mothers who received education on infant digestive health problems demonstrated better overall knowledge of digestive health problems. Conclusion: The rate of education regarding digestive health problems during infancy among first-time mothers was < 50%. Furthermore, mothers educated on infant digestive health issues exhibited improved knowledge. Therefore, it is necessary to provide appropriate pre-education to primiparous common gastrointestinal health issues in infants.

The purpose of this study was to examine relation between perception on hospice and attitude toward death to provide baseline data for the development of programs for hospice or death-related education for university students. The survey was performed on 150 students in four universities in B metropolitan city. The data was collected from July 30 to August 13, 2019. Data were analyzed using descriptive analysis, t-test, ANOVA Pearson's correlation coefficient with the SPSS/WIN 26.0 program. The mean of perception on hospice score was 3.06 out of 4, of the attitude toward death, 'neutral acceptance', 'fear of death', 'death avoidance', 'approach acceptance', and 'escape acceptance' had average scores of 5.31, 3.77, 3.56, 3.15, and 3.06, respectively. There were significant differences in perception on hospice according to gender, major, and experience of hospice-related education and in attitude toward death according to gender, major, religion, subjective health status, experience of hospice-related education. The relationship between perception on hospice and neutral acceptance showed a significant positive correlation, and fear of death and death avoidance showed a significant negative correlation. Therefore, we need consider these variables to develop a hospice or death-related education program to enhance university students' attitudes to death and their perception of hospice.
