BACKGROUND/OBJECTIVE: As aging progresses, the number of patients with cognitive impairment also increases. Cognitive function is not generally correlated with diet, and there is debate over that association. Thus, the present study aimed to investigate the association between dietary intake and cognitive function among adults aged 50 years or older. SUBJECTS/METHODS: Between July 2017 and March 2018, 324 adults aged over 50 years from Gwangju Sun-Han hospital participated in a dietary survey. The frequency of food intake and related information were collected using a semi-quantitative food frequency questionnaire (SQ-FFQ) and determining the mini-mental state examination (MMSE) level for 276 participants. The association between dietary intake and cognitive function was assessed by performing logistic regression analysis. RESULTS: Depending on the MMSE score, the participants' age, education level, inhabitation status, medications, alcohol consumption, sleep duration, physical activity, and short geriatric depression scale score were significantly different (P < 0.05). Moreover, those participant characteristics were associated with either decreased or increased odds ratios (OR) for the risk of mild cognitive impairment (MCI). Based on analysis of the participants' intake of 112 detailed food items, which were categorized into 20 food types, intakes of cooked white rice (< 2 times/day compared with ≥3 times/day) (P < 0.05), properly cooked rice with other grains and legumes (P < 0.001), fruits (P < 0.05), milk (low fat and normal) (P = 0.044), liquid-type yogurt (P = 0.019), and curd-type yogurt (P = 0.015) were found to significantly decrease the OR for the risk of MCI. CONCLUSIONS: Associations were significant between the risk of MCI and the intake of certain food types. Specifically, a moderate intake of cooked white rice and an adequate intake of whole grains, fruits, milk, and dairy products were associated with reduced risks of MCI among adults aged over 50 years.

Fifty-four adenocarcinomas of stomach were investigated to assess the expression of p21 and p53 using an immunohistochemical method. The relationship between p21 and p53 expression and the clinicopathologic parameters were analysed. The staining pattern of p21/p53 were: p21+/p53+, p21-/p53+, p21+/p53-, and p21-/p53- in 30, 12, 8, and 4 cases, respectively. Loss of p21 expression was observed in 16 of 54 tumor tissues (29%). p21 expression, however, had an inverse correlation with vascular invasion and depth of tumor invasion. The p21 and p53 protein expression showed intratumoral heterogeneity. In 63% of the adenocarcinoma, a proportional relationship was found between p21 and p53 immunostaining. The present results suggest that p53 independent induction of p21 expression may be involved in the molecular mechanism of these tumors, and expression of p21 protein may be related to a favorable prognosis in gastric adenocarcinomas.

PURPOSE: This study was done to identify correlations between fatigue and quality of life in clinical nurses. METHOD: A sample of 294 nurses working in 3 general hospitals answered a questionnaire containing Yoshitake's fatigue scale and WHOQOL-BREF. Data were analyzed using t-test, ANOVA and Pearson correlation coefficients. The SPSS/WIN 11.0 version program was used. RESULTS: The score for level of fatigue was 2.11 (52.7%) and quality of life, 2.89 (57.8%). The level of fatigue was highest in the physical domain followed by psychical and nervous-sensual domain in that order. There were statistically significant differences in scores of fatigue depending on the nurse's age, marital status, career, position, health status and present illness. Quality of life had the highest score in the social domain followed by physical, overall, psychological, and environmental domain in that order. There were statistically significant differences in scores on quality of life depending on nurse's age, marital status, career, position, health status and present illness. CONCLUSION: The relationship between fatigue and quality of life revealed a significant negative correlation. Based on this study, nursing administrators need to reduce the level of nurse fatigue by providing various programs, which improve quality of life.

BACKGROUND/AIMS: Hepatic fibrosis in rat induced by thioacet amide shares similar morphological and biochemical characteristics with human liver cirrhosis. Thioacetamide (T AA) initially induces accumulation of collagen in Disse space and eventually leads to macro- and micronodular cirrhos is. Ito cell was believed to play a main role in hepatic fibrosis. And it s activity was known to be regulated by the expression of various genes. But little has been discovered about the upstream signal trans duction pathway of these genes in hepatic fibrosis. The expression of genesrelated to Ito cell activity was regulated by many transcription factors , the activity of which was regulated by protein kinase C( PKC) is oforms. So it is s upposed that PKC could be as s ociated with fibrosis in liver. METHODS: We investigated the correlation of PKC is oforms and It ocell activity in the course of hepatic fibrosis using TAA induced rat liver cirrhosis model. We used six week- old male rats , and administered 0.03% TAA in drinking water. The animals were sacrificed at 9, 20, and 30 weeks after TAA administration. The degree of hepatic fibrosis was evaluated by measuring the total amount of collagen.-SMA immunohist ochemical st aining of liver tissue was done to determine the Ito cell activity. The expression pattern of PKC isoforms was investigated by West ern blotting. RESULTS: In TAA- treated group, collagen cont ent and Ito cell activity did not increase until 30 weeks and 20 weeks of treatment , respectively, while in control group collagen cont ent and Ito cell activity were not detected. Collagen content showed linear correlation with Ito cell activity. This implied that the proliferation of activated Ito cells was prior to the increase of collagen content. In view of expression pattern of PKC is oforms, PKC alpha showed no difference in TAA- treated group and control group. In TAA-treated group, PKCbeta1 exhibited increased level of expression in both particulate and cytosolic forms at 9 weeks, while PKCdelta and PKC epsilon showed striking shift to particulated form. After 20 weeks, all of the PKC beta1, delta, and epsilon degenerated and showed remarkably decreased level of expression. This suggested PKC alpha had no relation to hepatic fibrosis,while PKC beta1, delta, and epsilon, showing activity at 9 weeks, were related to fibrosis og liver. In response to fibrogenic factors, molecules engaged in intracellular signal transduction pathway like PKC beta1, delta, and epsilon, began to change prior to the increase of Ito cell activity, morphologic changes and alterations of collagen content. CONCLUSION: Our results strongly suggest that the activity of PKC isoforms play an important role in early step of hepatic fibrosis, while accompanying Ito cell activity do in later step.

PURPOSE: Assessment of the diameters of the aortic arches in the human fetus may be helpful in the prenatal diagnosis of aortic arch anomalies. The purpose of this study is to construct valuable reference ranges of fetal aortic arch for various fetal growth parameters in an unselected Korean population. METHODS: A prospective, cross-sectional study was performed in 98 normal singleton fetuses between 20 and 38 weeks of gestation. The transverse aortic arch diameter (TAD) and distal aorta isthmus diameter (AID) were measured in the longitudinal view during systole. The bi-parietal diameter (BPD), head circumference (HC), abdominal circumference (AC) and femur length (FL) were obtained at the same time. Ultrasound examinations were performed with a 2.0-6.0 MHz convex probe by abdominal ultrasound. RESULTS: TAD and AID as a function of gestational age (GA) was expressed by the regression equation TAD= -1.246+0.168 X GA, and AID = -1.341+0.180 X GA; TAD and AID are expressed in millimeters and GA in weeks. TAD and AID as a function of BPD was expressed by the regression equation TAD= -1.147+0.664 X BPD, and AID = -1.152+0.696 X BPD. TAD and AID as a function of HC was expressed by the regression equation TAD = -1.187+0.182 X HC, and AID = -1.350+0.198 X HC. TAD and AID as a function of AC was expressed by the regression equation TAD = -0.528+0.173 X AC, and AID = -0.533+0.183 X AC. TAD and AID as a function of FL was expressed by the regression equation TAD = -0.519+0.799 X FL, and AID = -0.601+0.860 X FL; BPD, HC, AC and FL are expressed in centimeters. Correlations were found to be highly statistically significant in relation to GA, BPD, HC, AC, and FL respectively (P<0.0001 in all). Normal mean of TAD and AID per GA, BPD, HC, AC and FL and 95% prediction limits were also defined, respectively. CONCLUSION: New reference ranges of fetal aortic arch related to other fetal bio-parameters representing fetal growth were obtained successfully. The normative date will be helpful in the prenatal accurate diagnosis of aortic anomalies and abnormal growth of fetal aortic arches in Korea.

Operating Room nurses are required to have special skills and knowledge to do their job. However, because there is no systematic education program, which considers special circumstances in the OR, novice nurses have a great deal of difficulty adapting themselves to the work environment. The purpose of this study is to develope a multimedia education program, which provides the systematic learning environment, so novice nurses can adapt to the OR environment more effectively. This study has been implemented according to Computer Assisted Instruction Design Model(Il-Joo Na and In-Sung Jung, 1990), which goes through the following steps; 1). Education program analysis 2). Development, evaluation 3). CompletionLearning goals, objectives, motive strategy, and analysis of the education program are analyzed by the concepts based on basic education materials for novice surgery nurses of 6 Medical Centers in Seoul and 'Development of the job training program for newly employed nurses in operating rooms. 'written by Ji-Young Yoon(2000). We divided 9 areas of the contents in surgery education; 1. Basic orientation 2. OR nurses' roles and responsibilities 3. Asceptic technique 4. Disinfection and sterilization 5. OR safety 6. OR nursing care 7. Surgical positioning 8. OR Material management 9. Anesthetic care. We selected asceptic technique, which is the most fundamental concept in OR nursing care. The program screens consist of cover screen, screen for guide, mini menu screen, and test screen. We distributed questionnaires to fifteen experts and investigated their opinions to analyze learning contents and effects of the Courseware. The education program was modified based on respones provided by experts. This study offers an educational program, which allows the individuals to choose the areas they want to learn. The program is easy to use, which encourages the individuals to search for additional information more than one area.

PURPOSE: Recently, incidences of chronic cough with allergic disease have been increased. The identification of specific allergens for chronically coughing children is significant for diagnosis, proper treatment and prevention. The aim of this study was to identify significant contributors for sensitization in chronically coughing children. METHODS: A total of 106 children, aged 1-6 years, visiting for chronic cough(>3 weeks), were tested for inhalant multiple allergosorbent assay(MAST), eosinophil count and total IgE. Parents completed a questionnaire on past history of atopy(infantile eczema) and bronchiolitis, family history of allergy, breastfeeding, smoking, pets and floor coverings at home. RESULTS: Significant contributors for sensitization were:age(4-6 years), infantile eczema, positive family history of allergy and smoking by family. CONCLUSION: We were able to identify significant contributors for sensitization in chronically coughing children.

PURPOSE: About 20% to 30% of patients with node-negative breast cancer die of systemic metastases in 10 years after surgery. This may be due to either early occult systemic spread before node metastasis or occult lymph node metastasis (OLNM) which is undectected by routine pathologic evaluation. The purpose of this study was to assess the incidence and its prognostic significance of OLNM in breast cancer. MATERIALS AND METHODS: Paraffin blocks of axillary lymph nodes from 50 patients with invasive breast carcinoma initially diagnosed as node-negative by routine histological examination were evaluated. All nodes were serially sectioned by 40 pm thickness interval, followed by hematoxylin-eosin (H-E) staining and cytokeratin immunohistochemical staining. RESULTS: OLNM were detected in 6 patients (12%) by immunohistochemical method; in 3 of these 6 patients, it were also detectable by serial sectioning and H-E staining. OLNM correlated with the primary tumor size (r=0.43, p <0.05). During mean follow- up of 57 months, there were 4 systemic recurrences and one death. Of 6 patients with OLNM, 2 had multiple systemic recurrences (33.3%). Of 44 patients without OLNM, in contrast, only 3 had systemic recurrences (6.8%). Five year disease-free survival rates of patients with and without OLNM were 66.7% and 93.0%, respectively (p=0.087). CONCLUSION: These results suggest that about 10% of patients with "node-negative" breast cancer have OLNM, and the presence of OLNM may have marginal prognostic significance. Serial sectioning and cytokeratin immunohistochemical staining of axillary lymph nodes should be considered as a part of the routine histologic examination especially in the patients with a large primary tumor.
