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.

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.

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.

The purpose of this study is to compare the dental health capacity of smokers and nonsmokers. This study included 9,856 adults aged 19 years or older. The data used for analysis were obtained from the Korean National Health and Nutrition Survey for the 6th round, 1st (2013), and 2nd round (2014). Statistical analysis was performed by analysis of complex sample survey data. The demographic characteristics and results of the comparison of the dental health capacity between smokers and nonsmokers were as follows: with regard to the tissue health (T-health) index, the sex, age, and education level were statistically significant in smokers and nonsmokers. For the functioning teeth (FS-T) index, age, income, and education levels were statistically significant in smokers, while sex, age, and education level were statistically significant in nonsmokers. In smokers, the age and education level were statistically significant for present teeth (PT), sound teeth (ST), and missing teeth (MT), while in nonsmokers, the sex, age, and education level were statistically significant for the same parameters (p<0.05). A comparison of the dental health capacity between smokers and nonsmokers yielded the following findings: the T-health index was higher in smokers, while the FS-T index was higher in nonsmokers. PT and ST were higher in nonsmokers (p<0.05). The results of this study show that the dental health capacity of nonsmokers was higher than that of smokers. Therefore, a clear difference was observed in the dental health capacity of smokers and nonsmokers. The results of this study can provide objective data for nonsmoking treatment.

This study assessed the risk and prevalence of anorexia as well as associated factors among home-dwelling elderly adults. The subjects were 419 elderly men (116) and women (303) aged 65 years and older ($76{\pm}5.6yr$) living in Korea. Data were collected by personal interviews using questionnaires. The collected data were analyzed by descriptive statistics and Pearson's correlation. The prevalence of anorexia was 35.1% among participants. Male elders (74.1%) had higher proportions of anorexia than female elders (20.1%) (P<0.001). Significant differences in the appetite were observed according to type of disease, depression, and activities of daily living (ADL) index. In the poor appetite group, central nervous system diseases were the primary illness in male elders (P<0.01), whereas endocrine diseases were the primary illness in female elders (P<0.01). Elders with good appetites had less symptoms of depression (P<0.001) and greater independence in ADL (P<0.001). These results explored the high prevalence of anorexia in geriatric populations in Korea and its impact on elderly nutritional status and health. Further research should be performed to identify the causes of anorexia and establish an intervention protocol allowing the early diagnosis of anorexia.

The purpose of this study was to identify the characteristics of consumers who purchase home meal replacements (HMR) and to analyze the differences for frequency of use, preference, satisfaction, and repurchase intention based on HMR product categories. The subjects were adults in their twenties or older, who had used HMRs and lived in Seoul and the Gyeonggi Province of Korea. Five-hundred and fifty subjects were chosen by random sampling, and questionnaires were distributed from March 12 to 30, 2005. A total of 451 questionnaires were returned (the rate of return was 82%). The primary results of the study are as follows. First, by analyzing for differences based on the demographical characteristics of the HMR consumers, men had higher 'frequencies of use' and preference, whereas women had higher satisfaction and 'intentions to purchase again.' This implies that HMRs assist women who are usually in charge of home food preparation, based on time and cooking effort; hence a higher satisfaction among the women. Second, by analyzing for differences based on the characteristics of HMR consumers who ate the products, 'frequency of use' (p<.001), preference (p<.01), satisfaction (p<.001), and 'intention to repurchase' (p<.001) for the 'ready to eat' HMR category, by the person who prepared the food, were significantly higher for those subjects in their 20s than for those in other age groups. As for persons influenced by the meal, the teen age group had significantly lower 'frequency of use'(p<.001), preference (p<.05), satisfaction (p<.01) and 'intention to repurchase' (p<.01) than other age groups. 'Frequency of use' (p<.001) and preference (p<.05) were lower if the person influenced by the meal was one's spouse or child than if the person influenced by the meal was oneself. Third, regarding the preference for eating at home or eating out, 'frequency of use' was significantly higher than the other analyzed factors for the 'ready to eat,' 'ready to heat,' and 'ready to end-cook' HMR categories. In short, the 'frequency of use' for HMRs was higher for those who preferred to eat at home versus eating out, simply as a result of being bored with eating out, which is essentially the reason for the origin of HMR.

Purpose : This study investigated the validity of crosswalk signal time length with regards to elderly stroke patients. Methods : We recruited 60 elderly adults sixty years of age or older for our study. The participants were divided into three groups.Group A consisted of 20 healthy participants with no walking aids. Group B consisted of 20 stroke patients with no walking aids. Group C consisted of 20 stroke patients using a cane as a walking aid. We measured the walking times of participants for 7 m, 14 m and 21 m lengths. Results : Using an independent t test, there was a statistically significant difference in the walking times between Group A and Group B for all lengths. There was a statistically significant difference in the walking times between Group A and Group C for all lengths. There was no statistically significant difference in the walking times between Group B and Group C. There was a statistically significant difference between the three group when using ANOVA. Conclusion : From the results of this study, we infer that the signal times at crosswalks are inappropriate for elderly stroke participants who use a cane as a walking aid. Therefore further research should be conducted to determine the appropriate amount of additional time needed for the elderly to safely cross the street.

BACKGROUND/OBJECTIVES: The inverse relationships of combined fruits and vegetables intake with blood pressure have been reported. However, whether there are such relationships with salty vegetables has rarely been investigated in epidemiologic studies. We evaluated the relation of combined and separate intake of fruits, vegetable intakes, and salty vegetables, as well as sodium and potassium, with blood pressure among the middle-aged and elderly populations. SUBJECTS/METHODS: The present cross-sectional analysis of a prospective cohort baseline survey was performed with 6,283 subjects (2,443 men and 3,840 women) and free of hypertension, diabetes, cardiovascular diseases, and cancer. Dietary data were collected by trained interviewers using food frequency questionnaire. RESULTS: The significantly inverse linear trend of diastolic blood pressure (DBP) was found in fruits and non-pickled vegetables (81.2 mmHg in the lowest quintile vs 79.0 mmHg in the highest quintile, P for trend = 0.0040) and fruits only (80.9 mmHg in the lowest quintile vs 79.4 mmHg in the highest quintile, P for trend = 0.0430) among men. In contrast, sodium and sodium to potassium ratio were positively related with blood pressure among men (DBP, 78.8 mmHg in the lowest quintile vs 80.6 mmHg in the highest quintile, P for trend = 0.0079 for sodium; DBP, 79.0 mmHg in the lowest quintile vs 80.7 mmHg in the highest quintile, P for trend = 0.0199 and SBP, 123.8 mmHg in the lowest quintile vs 125.9 mmHg in the highest quintile for sodium/potassium). Kimchies consumption was positively related to DBP for men (78.2 mmHg in the lowest quintile vs 80.9 mmHg in the highest quintile for DBP, P for trend = 0.0003). Among women, these relations were not found. CONCLUSION: Fruits and/or non-pickled vegetables may be inversely, but sodium, sodium to potassium, and Kimchies may be positively related to blood pressure among men.

Purpose: This study was performed to identify the factors that change exercise behave. This study will also classify and identify the characteristics of excercise stages to which the elderly belong Also, to identify the processes of change which influence on the changes in exercise performed by the elderly. Methods: Convenient samples of 198 subjects over the age 60 in Seoul Korea(mean age=70) were selected from elderly communities and were all mentally conpetant older adults. The data were collected from April 1,1999 to May 30, 1999. The research instruments were measured the change in exercise (Marcus et al., 1992b), such as Stage of Change measure(Marcus et al,1992a). The data were analyzed by SAS Program. Results: 1. According to the measure of change without missing data, 191 subjects were distributed 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, the contemplation stage, the preparation stage, the action stage and the maintenace stage. 2. According to the factor analysis, 6 factors of change were identified as appropriate processes of change and were named by the researchers. The names were; 'Supportive helping relationship', 'Self cognitive determination', 'Environmental reinforcement', Consciousness raising', Reinforcement of negative condition and 'Conversion of negative condition'. 3. According to the stage of change, there were significant mean differences in the 'Supportive helping relationship(F=22.04, p=.0001)', 'Self cognitive determination (F=50.87, p=.0001)', 'Reinforcement of negative condition(F=7.84,p=.0006)'. 4. Through the discriminant analysis, it was found that Self cognitive determination is the most influential variable as one of the processes of change which can discrimiate the three stages of change (precontemplation, preparation, and maintenance). Also the next significant variable was Reinforcement of negative condition. Conclusion: The process of the dey change is one of concepts of The transtheoretical model known as strategies and the techniques people use as they go through the different stages of change. Even though this study is cross- sectional not longitudinal study, the finding of this study gives useful information for exercise intervention, by using this strategy of exercise for elderly in different stages of change in exercise.
