In order to investigate the relationship between intake conditions of health food and health-related factors by residence and sex in Tong-Young area, a survey was carried out from 1,303 adults. Health foods were classified 3 groups including vitamin and mineral supplements, toner foods and manufactured health food supplements. Health-related factors were stress, fatigue, smoking and drinking. The $29.5\%$ of the subjects had taken some health food for health. Especially the male took more toner foods habitually than the female did. In take of vitamin and mineral supplements by residence, there was a significant difference $(p\leq0.01)$ as follows. The subjects in island $(20.0\%)$ who took vitamin/mineral supplements were about two times as compared with the subjects in Dong $(10.8\%)$, or Eub-Myeon $(10.0\%)$. The subjects taking supplementary food replied over fair $(82.8\%)$, the subjects taking toner food replied over fair (90.3$\%$) scored higher than who replied bad or very bad in self-perceived health status. Therefore, the better the subjects felt self-perceived health status, the more they took health foods for health themselves. In self-perceived stress status, the subjects who replied a little $(50.0\%,\;45.3\%)$ or little $(19.9\%,\;26.4\%)$, took vitamin and mineral supplements or manufactured health foods a lot. In toner food there was a significant correlation $(p\leq0.05)$ as follows. The less the subjects felt stress, the more they took dietry supplement. No smoker $(12.9\%)$intake rate of vitamin and mineral supplements was higher than smoker $(8.8\%)$. Smokers $(6.5\%)$ intake rate of toner food was higher than no smoker $(4.0\%)$. It was not significant the relationship between intake condition of health food and drinking. The main motivation for taking health food were by self-decision and invitation of friends or neighbors.

Objective: To develop and validate a model using radiomics features from apparent diffusion coefficient (ADC) map to diagnose local tumor recurrence in head and neck squamous cell carcinoma (HNSCC). Materials and Methods: This retrospective study included 285 patients (mean age ± standard deviation, 62 ± 12 years; 220 male, 77.2%), including 215 for training (n = 161) and internal validation (n = 54) and 70 others for external validation, with newly developed contrast-enhancing lesions at the primary cancer site on the surveillance MRI following definitive treatment of HNSCC between January 2014 and October 2019. Of the 215 and 70 patients, 127 and 34, respectively, had local tumor recurrence. Radiomics models using radiomics scores were created separately for T2-weighted imaging (T2WI), contrast-enhanced T1-weighted imaging (CE-T1WI), and ADC maps using non-zero coefficients from the least absolute shrinkage and selection operator in the training set. Receiver operating characteristic (ROC) analysis was used to evaluate the diagnostic performance of each radiomics score and known clinical parameter (age, sex, and clinical stage) in the internal and external validation sets. Results: Five radiomics features from T2WI, six from CE-T1WI, and nine from ADC maps were selected and used to develop the respective radiomics models. The area under ROC curve (AUROC) of ADC radiomics score was 0.76 (95% confidence interval [CI], 0.62-0.89) and 0.77 (95% CI, 0.65-0.88) in the internal and external validation sets, respectively. These were significantly higher than the AUROC values of T2WI (0.53 [95% CI, 0.40-0.67], p = 0.006), CE-T1WI (0.53 [95% CI, 0.40-0.67], p = 0.012), and clinical parameters (0.53 [95% CI, 0.39-0.67], p = 0.021) in the external validation set. Conclusion: The radiomics model using ADC maps exhibited higher diagnostic performance than those of the radiomics models using T2WI or CE-T1WI and clinical parameters in the diagnosis of local tumor recurrence in HNSCC following definitive treatment.

Recently, dietary pattern analysis was emerged as an approach to examine the relationships between diet and risk of chronic diseases. This study was to identify groups with population who report similar dietary pattern in Korean genome epidemiology study (KoGES) and association with several chronic diseases. The cohort participants living in Ansung and Ansan (Gyeonggi province) were totally 10,038. Among those, 6,873 subjects with no missing values in food frequency questionnaire were included in this analysis. After combining 103 food items into 17 food groups, 4 dietary factors were obtained by factor analysis based on their weights. Factor 1 showed high factor loadings in vegetables, mushrooms, meats, fish, beverages, and oriental-cereals. Factor 2 had high factor loadings in vegetables, fruits, fish, and factor 3 had high factor loadings in cereal-oriental, cerial-western and snacks. Factor 4 showed positive high factor loadings in rice and Kimchi and negative factor loadings in mushrooms and milk and dairy products. Using factor scores of four factors, subjects were classified into 3 clusters by K-means clustering. We named those 'Rice and Kimchi eating' group, 'Contented eating' group, and 'Healthy and light eating' group depending on their eating characteristics. 'Rice and Kimchi eating' group showed high prevalence in men, farmers and 60s. 'Contented eating' group and 'Healthy and light eating' group had high prevalence in women, people living in urban area (Ansan Citizen), with high-school education and above, and a monthly income of one million won and more. 'Contented eating' group appeared lower distribution proportion in the sixties and 'Healthy and light eating' group does higher in the fifties. 'Contented eating' versus 'Rice and Kimchi eating', odds ratio for hypertension, diabetes, metabolic syndrome and obesity significantly decreased after adjusting age and sex (OR=0.64, 0.73, and 0.85 respectively, 95% CI). Although our results were from a cross-sectional study, these imply that the dietary patterns were related to diseases.

Objective: To develop a model incorporating radiomic features and clinical factors to accurately predict acute ischemic stroke (AIS) outcomes. Materials and Methods: Data from 522 AIS patients (382 male [73.2%]; mean age ± standard deviation, 58.9 ± 11.5 years) were randomly divided into the training (n = 311) and validation cohorts (n = 211). According to the modified Rankin Scale (mRS) at 6 months after hospital discharge, prognosis was dichotomized into good (mRS ≤ 2) and poor (mRS > 2); 1310 radiomics features were extracted from diffusion-weighted imaging and apparent diffusion coefficient maps. The minimum redundancy maximum relevance algorithm and the least absolute shrinkage and selection operator logistic regression method were implemented to select the features and establish a radiomics model. Univariable and multivariable logistic regression analyses were performed to identify the clinical factors and construct a clinical model. Ultimately, a multivariable logistic regression analysis incorporating independent clinical factors and radiomics score was implemented to establish the final combined prediction model using a backward step-down selection procedure, and a clinical-radiomics nomogram was developed. The models were evaluated using calibration, receiver operating characteristic (ROC), and decision curve analyses. Results: Age, sex, stroke history, diabetes, baseline mRS, baseline National Institutes of Health Stroke Scale score, and radiomics score were independent predictors of AIS outcomes. The area under the ROC curve of the clinical-radiomics model was 0.868 (95% confidence interval, 0.825-0.910) in the training cohort and 0.890 (0.844-0.936) in the validation cohort, which was significantly larger than that of the clinical or radiomics models. The clinical radiomics nomogram was well calibrated (p > 0.05). The decision curve analysis indicated its clinical usefulness. Conclusion: The clinical-radiomics model outperformed individual clinical or radiomics models and achieved satisfactory performance in predicting AIS outcomes.

The purpose of this study is to develop self-efficacy promotion program and to test its effects on self-efficacy, self-care, physiologic index of hemodialysis patients after applying this program to them. Preliminary study was carried out to identify the levels and types of self-care, self-efficacy of hemodialysis patients. To develop self-efficacy promoting program, several discussions with nursing professors and nurse specialists on hemodialysis patients were made after in-depth literature review on the area. Through these processes, the self-efficacy promoting program including 20 minutes long videotape and other counciling documents were completed. This videotape consisted of specific self-care techniques for hemodialysis patients including management of fistula, measurement of blood presure and body weight, special diets, medications, exercise and rest, management of physical problems and social adjustment. Two group equivalent pre and post test quasai-experimental research design was used in this study. The total subjects were 34 hemodialysis patients who received hemodialysis three time per week at 1 university hospital. Seventeen experimental group subjects were matched with control group subjects in sex and age. Data were analysed with the SPSS window program. Homogeniety between experimental and control group pretest data was tested by x$^2$ and t-test. There were no significanct differences in general characteristics, illness history, specific self-efficacy and self-care between the two groups. The differences of general self-efficacy of two groups were tested with the Repeated Measure ANCOVA because of significant differences of pretest data of general self efficacy between two groups. The differences of self-efficacy and self-care of two groups were tested with Repeated Measure ANOVA and the differences of physiologic indecies including blood potassium level and blood phosphorus level and interdialytic weight gain were tested by t-test. The results were as follows: 1. There was no significant difference in general self-efficacy between the two groups over four different time, and no interaction by groups and by time. 2. There was significant difference in specific self-efficacy between the two groups over four different time, and interaction by groups and by time. 3. There was significant difference in self-care between the two groups over four different time, and interaction by groups and by time. 4. There were no significant differences of blood potassium level and blood phosphorus level, but there was significant difference of interdialytic weight gain between the two groups. From the results above, it can be concluded that the self-efficacy promotion program for hemodialysis patients was effective to improve degree of specific self-efficacy and self-care and to decrease interdialytic weight gain. Considering results, the followings are recommended: 1) Repeated studies are needed for another hemodialysis patients. 2) This program can be used for improving degree of self-efficacy and self-care of hemodialysis patients by nurse practitioner and nurse educator.

Objective: The aim was to evaluate roles of vitamin D3 (VD3) and beta-carotene (BC) in the development of esophageal squamous cell carcinoma (ESCC) in a high-risk area, Huai'an District, Huai'an City, China. Methods: 100 new ESCC diagnosed cases from 2007 to 2008 and 200 residency- age-, and sex-matched healthy controls were recruited. Data were collected from questionnaires, including a food frequency questionnaire (FFQ) to calculate the BC intake, and reversed phase high-performance liquid chromatography (RP-HPLC) was used to measure the serum concentrations of BC and VD3. Odds ratios (OR) and 95% confidence intervals (CI) were calculated in conditional logistic regression models. Results: The average dietary intake of BC was $3322.9{\mu}g$ (2032.4-5734.3) in the case group and $3626.8{\mu}g$ (1961.9-5827.9) in control group per capita per day with no significant difference by Wilcoxon test (p>0.05). However, the levels of VD3 and BC in the case group were significantly lower than in the control group (p<0.05). The OR values of the highest quartile and the lowest quartile of VD3 and BC in serum samples were both 0.13. Conclusion: Our results add to the evidence that high circulating levels of VD3 and BC are associated with a reduced risk of ESCC in this Chinese population.

The purpose of this study was to investigate the psychosomatic health status of printers. The 77 printers and 24 control group were analysed about salary, drinking, smoking, education, sex, marriage, age and working age by the THI (Todai Health Index) questionaire. THI was modified from CMI(Cornell Medical Index) and developed by Tokyo University Research Team in Japan. The resuts obtained were summarized as follows. 1. The printers, who get more salary showed high score about mental conplaints, especially, mental irritability(j), nervusness (E), lie Scale(L), aggressiveness(F) and irregualr life(G) and lower salary showed generally high score about physical complaints, especially, mouth and anus (D), digestive symptom(C) multiple subjective symptom(I). 2. According to the printers drinking amount shows the difference, eg nondrinker scored higher on mouth and anus(D), 90mg/week drinker scored higher on multiple subjective symptom(I), digestive symptom(C), depression(K), nervousness(E), and irregular life(G), 91~179mg/week drinker scored higher on impulsiveness(H), mental irritability(J), 270~359mg/week drinker scored higher on respiratory(A), lie scale (L) and aggressiveness (F). 3. The nonsmoker scored high level on mouth and anus(D), mental irritability(J). The previous smoker scored on multiple symptom(I), eyes and skin(B), digestive(C), lie scale(L), and depression(K). The present smoker scored on respiratory(A), impulsivehess(H), aggressiveness(F), nervousness(E), and irregular life(G). 4. According to the printers working age showed almost high score about subjective symptoms on 1~3 year. 5. Men printers high scored on respiratory(A). lie scale(L), aggressiveness(F), women printers scored about mental complaints, especially, impulsiveness(H), mental irritability(J), depression (K), nervousness (E). 6.

BACKGROUND/OBJECTIVES: The aim of this study was to examine differences in nutrient intake and food consumption by the presence of metabolic syndrome in Korean adults. SUBJECTS/METHODS: Study subjects in this cross-sectional study were recruited from four outpatient clinics in and near the Seoul metropolitan area of South Korea between 2006 and 2012. A total of 668 subjects (413 men and 255 women) aged ${\geq}30y$ were included in the final data analyses. For each subject, daily nutrient intake and food consumption were calculated using three days of dietary intake data obtained from a combination of 24-hour recalls and dietary records. To evaluate food consumption, mean number of servings consumed per day and percentages of recommended number of servings for six food groups were calculated. Metabolic syndrome was defined using the National Cholesterol Education Program Adult Treatment Panel III criteria. The general linear model was performed to examine differences in nutrient intake and food consumption by sex and the presence of metabolic syndrome after adjustment for potential confounding variables. RESULTS: Nutrient intake did not differ by the presence of metabolic syndrome in both men and women. Men with metabolic syndrome had lower consumption and percentage of the recommendation for fruits compared with those without metabolic syndrome (1.6 vs. 1.1 servings/day, P-value = 0.001; 63.5 vs. 49.5%, P-value = 0.013). Women with metabolic syndrome showed lower consumption and percentage of the recommendation for dairy foods than those without metabolic syndrome (0.8 vs. 0.5 servings/day, P-value = 0.001; 78.6 vs. 48.9%, P-value = 0.001). CONCLUSIONS: Low intakes of fruits and dairy foods might be associated with the risk of having metabolic syndrome among Korean adults. Dietary advice on increasing consumption of these foods is needed to prevent and attenuate the risk of metabolic syndrome.

This study was performed to get basic data for gloves size system and pattern planning suitable Korean hand shape. Data was collected through measuring hand size of man and woman from age 18 to 30 as subjects living in metropolitan area. by analysing the measured data, the difference in man and woman and the gloves size system was established. The results of study are as follows: 1. The Deviation of hand girths and hand lengths was larger than that of hand width in both man group and woman group. In all items. deviation in man was larger than woman. 2. In sex difference, there was difference between mall group and woman group in all items. In age difference, there was difference between mall group and woman group in mainly girth and the difference was bigger in group under 24 years old than in group over 24 years old. 3. The weight showed the highest $correlation(r{\geqq}0.8)$ with girths and high correlation with widths $(r{\geqq}0.7).$ The height showed the highest positive $correlation(r{\geqq}0.8)$ with and elbow length and high correlations with width and girths item. There were high positive correlation between vertical lengths in hand and between horizontal lengths but low correlation between vertical lengths and horizontal lengths. 4. The basic parts for gloves size system, hand lengths and hand girths were divided into 1cm interval. The results shouted that $91.0\%$ of man group were ranged from 18cm to 20cm section and $92.4\%$, of woman group were ranged from 16cm to 18cm section. 5. The interval which has the highest covet· rate was hand length 19cm and hand girth 20cm interval which covered $18.65\%$ of man group. The intervals which showed cover rate more than $5\%$ was total 7 and they covered $73.1\%$ of man group. The interval which has which has the highest cover rate was hand length 17cm and hand girth 17cm interval which covered $21.37\%$ of woman group. The intervals which showed cover rate more than $5\%$ was total 6 and they covered $72.5\%$ of total woman group.

Purpose: Among the various surgical methods used for the effective treatment of cystic lesion in the jaws historically, decompression procedure has some of superior prognosis compare to direct enucleation. In order to propose the efficacy of decompression we performed this retrospective study to compare decompression procedure with one-stage enucleation in clinical results and prognosis. Patients and Methods: We reviewed 175 patients who had been histopathologically diagnosed cystic lesions from 1996 to 2000 in our department. Patients who had been received decompression alone or secondary enucleation after decompression were 31 cases, and enucleation alone were 144 cases. The age and sex of the patients, the area, size, and histological type of the lesions, and detailed operation and complications including recurrence were investigated. The minimal follow-up period was 2 years. Results: In 31cases of decompression, male patients were 22cases(71%) similar to male predilection(62.3%) in total 175 cases. Cystic lesions were developed evenly in all age groups totally. Decompression was mainly performed in teenagers but enucleation was used in elder decades. In decompression cases the lesions were located in mandibular posterior, maxillary posterior, mandibular anterior, and maxillary anterior in order, which had some differences in total and enucleation cases. In enucleation cases, less than 3cm in size was 77.1% but larger than 3cm was 93.5% in decompression cases. Histopathologically, dentigerous cysts(54.8%), unicystic ameloblastomas(16.1%), and odontogenic keratocysts(12.9%) were seen in decompression cases and no recurrence or metaplasia and infection was observed. On the other hand, permanent tooth loss, numbness, recurrence, and so on were accompanied after enucleation. Conclusion: Although decompression procedure has disadvantages such as many of visiting times and slow recovery of the surgical defect, decompression is the best choice of treatment for large cystic lesions of the jaws, because it prevents functional and cosmetic defect, allows bone regeneration, and makes easy secondary enucleation.
