To explore the relationship between economic status and food and nutrient intake patterns, the 2001 National Health and Nutrition Survey result was analyzed. Dietary intake data of 6,978 Korean adults of 20 years and older who participated in the 2001 National Health and Nutrition Survey were used along with their demographic data. Economic status of the subjects was classified into the following 4 groups based on the self-reported average monthly income of household with reference to the minimum monthly living expenses (MLE) in 2001 : low < $100\%$ MLE $\leq$ middle < $200\%$ MLE $\leq$ high < $300\%$ MLE $\leq$ higher, Individuals in the higher income class had significantly higher mean intake for most of the nutrients including energy, protein, carbohydrate, fat, calcium, thiamin, riboflavin, niacin and vitamin C, and a higher percentage of energy intake from fat. In addition, they consumed more animal foods including meats, eggs, fish/shellfish, milk/dairy products and fats. On the other hand, the mean intakes of individuals in the lower economic class for calcium, vitamin A, and riboflavin were lower than $75\%$ of RDAs. And, there was a predominant difference in contribution of fat to total energy intake among the groups of different economic status. These results showed that household income is an important factor influencing the food and nutrient intake patterns of the Korean adult population. Although individuals at different age classes may respond differently to a change in economic status, developing and implementing nutrition policy and intervention programs for those nutritionally vulnerable groups should consider the economic status as an important factor to customize and differentiate the content of the Program.

The purpose of this study is related to the entrepreneurial activation of middle-aged and the elderly people for identifying the influence of entrepreneurial competency and entrepreneurial motivation on the entrepreneurial intentions and the mediating effects of opportunity search. In order to achieve the purpose of this study, a survey was conducted targeting the middle-aged and the elderly people in the ages of 40~60 years, and among 250 copies of collected questionnaires, 230 copies were finally used. SPSS 24.0 program was used for analysis. Results are as follows. First, the entrepreneurial competency had a positive effect on entrepreneurial intentions. Specifically, it has been proved that information competency, experience competency, network competency had a significant influence on entrepreneurial intentions. Second, the entrepreneurial motivation had a positive effect on entrepreneurial intentions. Furthermore, it has been proved that independence maintenance, wealth creation had a positive effect on entrepreneurial intentions, but cost of living were rejected. Third, the results of verifying the mediating relationship of opportunity search showed that the opportunity search has performed a mediating role in the effect of experience competency, network competency, and independence maintenance on entrepreneurial intentions.

Type II membranoproliferative glomerulonephritis (Dense deposit disease) is an acquired primary glomerular disease characterized by electron microscopic evidence of a continuous dense membrane deposition replacing the lamina densa. It is a subtype of idiopathic membra- noproliferative glomerulonephritis, and was described as a separate entity by Berger and Galle in 1963. It frequently occurs in older chilren and young adults and the clinical course is variable, but is generally progressive. The presenting feature is nephrotic syndrome in many patients, and proteinuria and hematuria are also seen frequently. The purpose of this paper is to present a case of DDD (Dense deposit disease) from a 10 year old boy who was diagnosed as a acute poststreptococcal glomurulonephritis with protenuria, hematuria, and facial edema by renal biopsy 4 years ago.

The WHtR (waist to height ratio) and ABSI (a body shape index) are indicators that reflect abdominal obesity. This study examined the insulin resistance and metabolic syndrome prediction ability of ABSI and WHtR. In this study, 4,395 people aged 20 years or older, who underwent physical examinations at a General Hospital in Gyeonggi-do from January 2017 to September 2017 were assessed on a cross section survey. Metabolic syndrome was defined according to the criteria of the AHA/NHLBI. Insulin resistance was judged to be insulin resistance when the HOMA-IR value was 3.0 or more. Both men and women showed a stronger correlation between WHtR and the metabolic risk factors than ABSI. The AUC value of WHtR and ABSI was 0.849 and 0.676, respectively (p<0.001). The AUC value of WHtR and ABSI for predicting insulin resistance was 0.818 and 0.641, respectively (p<0.001). In conclusion, the ABSI has low predictive power of insulin resistance and metabolic syndrome whereas the WHtR has good predictive power for metabolic syndrome and insulin resistance.

Epilepsy, characterized by enduring the predisposition to generate epileptic seizures, was conceptually defined in 2005 as a disorder of the brain. According to the international league against epilepsy in 2014 that there is a high risk of recurrence within 10 years. The existence of interictal epileptiform discharges (IEDs) at the Electroencephalography (EEG) is an important risk factor for a possible recurrence of seizures, disproving that the seizures may increase. The purpose of this study was to analyze the correlation between recurrent seizures and epilepsy EEG findings in patients with IEDs, which was carried out to serve as the basis for the EEG to predict the prognosis of patients with epilepsy. This study included 432 adults older than 20 years of age who care for patients with epilepsy at Seoul National University Hospital, between June 2007 and December 2010. The results showed no difference between men and women in the EEG epilepsy disease, but there was a difference between various age groups. Correlation analysis showed a negative correlation between recurrence of seizures and age; it showed a positive correlation between recurrence and IEDs. In addition, age was associated with a predictive power of 10.9% and IEDs showed a predictive power of 15% on recurrent seizures. Therefore, EEG is considered as a very important test in epilepsy diagnosis. Therefore, further studies are necessary on the relationship between seizure recurrence and EEG.

Recently, there have been many studies on the relationship between the bone metabolism and the mechanism of diabetes. In those studies, it was shown that osteocalcin can be involved in the treatment of type 2 diabetes. Therefore, this study examined the correlation between osteocalcin and HbA1c. From January 1, 2015 to December 31, 2016, a total of 714 adults aged 40 years or older ($70.8{\pm}10.4years$, 452 males), in whom both osteocalcin and HbA1c checked in a general hospital in Gwangju, were enrolled in the study. The serum calcium, total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol, and 25-(OH) vitamin D were measured and basic information, such as the height and weight, were recorded. There was a weak negative correlation (r=-0.183, P<0.001) between the osteocalcin and HbA1c levels in diabetic patients but a negative correlation (r=-0.251, P<0.001) when adjusted by all other study variables. The present study showed that there was a negative correlation between the osteocalcin and HbA1c levels in diabetic patients. The relationship between the bone metabolism and the incidence of diabetes mellitus should be studied based on the influence of biological mechanisms and associated factors of bone and glucose metabolism.

This study was carried out to investigate the post stroke depression (PSD) occurrence in acute stroke patients and to identify the factors that influence PSD. The study subjects were 104 adults in their 20s or older who were scheduled to be discharged due to inpatient treatment for ischemic stroke in two hospitals. Data were collected using Post Stroke Depression Scale for PSD, Multidimensional Scale of Perceived Social Support for social support, National Institutes of Health Stroke Scale for stroke severity, and Modified Rankin Scale for disability. The average length of stay after stroke onset of the study subjects was 5.9±2.1 days, and 79.8% were within 7 days. Stroke severity score was an average of 2.4±2.5 out of 42 points, and disability score was an average of 1.6±1.1 out of 6 points. Among the subjects, 32.7% had mild or more severe depression after stroke. The subjects with no religion, severe disability, high stroke severity, and less family support had a higher likelihood of experiencing PSD. These results show that depression can appear in the early stages of stroke onset. Therefore, it is necessary to develop nursing guidelines for depression intervention after acute stroke, including continuous early assessment of depression from the acute phase of stroke and religion or family support.

Purpose : This study was carried out to identify the factor of decisional balance for exercise. This was composed of a set of variables at the level of decision making when the elderly decide to do exercise. It was used to classify and identify the characteristics of the stages of change for exercise to which the elderly belong, and was used to identify the variables of decisional balance which influence the stage of change for exercise in the elderly. Methods : Convenient samples of 198 subjects over age 60 in Seoul( mean age=70) were selected from community living, mentally competant older adults and the data was collected from April 1, 1999 to May 31, 1999. The research instrument was the Decisional Balance Measure for Exercise(Marcus & Owen., 1992), Stage of Change Measure(Marcus et al,1992). The data was analyzed by SAS Program. Results: 1. According to stage of change measure, without missing data,191 subjects were distributed in each stage of change for exercise : 50 subjects(26.1%), 7 subjects (3.6%), 52 subjects(27.2%), 4 subjects(2%), and 78(40.8%) belonged to the precontemplation stage, contemplation stage, preparation stage, action stage and maintenace stage. 2. Factor analysis identified 3 factors of decisional balance as appropriate factors for exercise of the elderly and named by researchers; 1)'Perceived Physical-psychological benefit', 2)'Perceived Physical-psychological burden', and 3)'Perceived time burden'. 3. The analysis of variance showed that the two components Perceived Physical - psychological benefit(F=45.95, P=.0001), and Perceived Physical-psychological burden (F=26.52, P=.0001) were significantly associated with stage of change. 4. Through the discriminant analysis, it was found that both 'Self Perceived Physical - Psychological benefit' and 'Perceived Physical-Psychological burden' were the influential variables in discriminating the three stages of change(pre-contemplation, preparation, and maintenance). Conclusion : Results are consistent with the application of the Transtheoretical model, which has been used to understand how people change health behaviors. Even though this study is a cross-sectional, not a longitudinal study, the findings of this study give useful information for exercise intervention about especially the factors relating to decision making for exercise of the elderly in the different stages of change of exercise.

Background: Colorectal cancer (CRC) is one of the prime causes of mortality around the globe, with a significantly rising incidence in the Middle East region in recent decades. Since detection of CRC in the early stages is an important issue, and also since to date there are no comprehensive epidemiologic studies depicting the Middle East region with special attention to the average risk group, further investigation is of significant necessity in this regard. Aim: Our aim was to investigate the prevalence of preneoplastic and neoplastic lesions of the colon in an average risk population. Materials and Methods: A total of 1,208 eligible asymptomatic, average- risk adults older than 40 years of age, referred to Firuzgar Hospotal in the years 2008-2012, were enrolled. They underwent colonoscopy screening and all polypoid lesions were removed and examined by an expert gastrointestinal pathologist. The lesions were classified by size, location, numbers and pathologic findings. Size of lesions was measured objectively by endoscopists. Results: The mean age of participants was $56.5{\pm}9.59$ and 51.6% were male. The overall polyp detection rate was 199/1208 (16.5 %), 26 subjects having non-neoplastic polyps, including hyperplastic lesions, and 173/1208 (14.3%) having neoplastic polyps, of which 26 (2.15%) were advanced neoplasms. The prevalence of colorectal neoplasia was more common among the 50-59 age group. Advanced adenoma was more frequent among the 60-69 age group. The majority of adenomas were detected in the distal colon, but a quarter of advanced adenomas were found in the proximal colon; advance age and male gender was associated with the presence of adenoma. Conclusions: It seems that CRC screening among average-risk population might be recommended in countries such as Iran. However, sigmioidoscopy alone would miss many colorectal adenomas. Furthermore, the 50-59 age group could be considered as an appropriate target population for this purpose in Iran.

Purpose: To evaluate the outcomes and prognostic factors in children with extracranial germ cell tumors (GCTs) treated at a single institution. Methods: Sixty-six children diagnosed with extracranial GCTs between 1996 and 2012 were included in the study. Primary treatment was surgical excision, followed by six cycles of cisplatin-based chemotherapy. The survival rates were compared according to the International Germ Cell Cancer Cooperative Group classification used for GCTs in adults to validate the classification guidelines for GCTs in children. Results: The median patient age was 4.4 years. In 34 patients (51.5%), the primary tumor site was the gonad. Extragonadal GCTs were detected in 32 patients. The 5-year overall survival and event-free survival (EFS) were $92.0%{\pm}3.5%$ and $90.4%{\pm}3.7%$, respectively. In univariate analysis, tumor histology, metastasis, and elevated alpha-fetoprotein were not prognostic factors in children with extracranial GCTs. However, EFS was poorer in patients with mediastinal disease (n=12, $66.7%{\pm}13.6%$) than in those with nonmediastinal disease (n=54, $96.0%{\pm}2.8%$) (P=0.001). The 5-year EFS was lower in patients older than 10 years, (n=21, $80.0%{\pm}8.9%$) compared with those younger than 10 years (n=45, $95.2%{\pm}3.3%$) (P=0.04). Multivariate analysis identified the mediastinal tumor site as the only independent prognostic factor. Conclusion: The prognosis of children with extracranial GCTs was favorable. However, nongerminomatous mediastinal tumors were associated with poor survival in children. Further research is needed to improve the prognosis of children with malignant mediastinal GCTs.
