In this study, to evaluate the fatigue life of surface crack in welding material general structural rolled steel(SS400) was used and welding was performed by MIG butt process. After that, it was machined the same pattern`s initial surface flaw on each welding zone divided by welding metal zone(WM), heat affected zone(HAZ), base metal zone(BM) and boundaries. Using this specimen it could be well evaluated the fatigue life in welding zone. The result are summarized as follows: 1. In each welding zone surface fatigue crack varies from initial aspect ratio of two to semicircle shape at first, after that the aspect ratio of it is reduced gradually. Aspect ratio indicates largely in order of the boundary of HAZ and BM, BM and HAZ, the boundary of WM and HAZ and WM. 2. Surface fatigue crack growth rate is larger in surface direction compare with depth direction at first and it shows that approaches in two direction during fatigue crack propagate continuously. Fatigue crack growth rate indicates largely in order of the boundary of HAZ and BM, BM and HAZ, the boundary of WM and HAZ, and WM. 3. Fatigue life indicates largely in order of WM, the boundary of WM and HAZ, HAZ, BM and the boundary of HAZ and BM. 4. The ratio of initial life to fatigue life indicates largely in order of HAZ, the boundary of HAZ and BM, BM, the boundary of WM and HAZ, and WM. It belongs to 34% to 58% in welding zone.

Backgrounds:Frontotemporal dementia (FTD) is rarely associated with motor neuron disease (MND). This comorbidity (FTD-MND), a subtype of FTD, results in progressive dementia and muscle weakness. Among the few available reports of series of patients, however, there have been controversies about the clinical course of FTD-MND. This study, the first report of a series of FTD-MND patients in Korea, investigated demographic and clinical features, clinical course, and neuropsychological findings of nine patients with FTD-MND. Methods:Nine FTD-MND patients (2 men and 7 women with mean age 55.6±7.2 years) were selected among 45 FTD patients who met the FTD criteria proposed by the Lund and Manchester Groups. Their clinical and neuropsychological findings were analyzed retrospectively. Results:Mean age of onset was 54.3±8.0 years. The time interval from onset to death was 27±11.3 months. Presenting symptoms were personality change, hyperphagia, nonfluent speech or motor weakness. In most cases (8/9), dementia preceded the muscle weakness;in only one patient the muscle weakness preceded the cognitive decline. Regarding the muscle weakness, bulbar symptoms occurred earlier than limb weakness in four patients;bulbar and limb weakness occurred simultaneously in another four patients;in the remaining one patient limb weakness preceded bulbar weakness. Neuropsychologic tests showed no specific patterns but diffuse dysfunction in all cognitive domains. Conclusions:Our study suggests that FTD-MND predominantly affects the bulbar muscles rather than the limb muscles in early stage and symptoms related to MND occurs later than those related to FTD. The time from diagnosis to death was 10.6±6.5 months, suggesting that FTD-MND is a rapidly progressive disease. This rapid clinical course may account for our neuropsychological findings that showed general cognitive deficits father than predominant frontal dysfunctions.

Although noodles occupy an important place in the dietary lives of Americans, up until the present time research and in-depth data on the noodle consumption patterns of the US population have been very limited. Therefore, this study aimed to analyze the food consumption and diet patterns of noodle consumers and non-consumers according to age, gender, income, and ethnicity. The 2001-2002 NHANES databases were used. The NHANES 2001-2002 data showed that noodle consumers reporting noodle consumption in their 24-h recall were 2,035 individuals (23.3% of total subjects). According to the results, the mean noodle consumption was 304.1 g/day/person, with 334.3 g for males and 268.0 g for females. By age, the intake of those in the age range of 9-18 years old ranked highest at 353.0 g, followed by the order of 19-50 year-olds with 333.5 g, 51-70 year-olds with by 280.4 g, older than 71years old with 252.3 g, and 1-8 year-olds with 221.5 g. By gender, males consumed more noodles than females. Also, according to income, the intake amount for the middle-income level (PIR 1~1.85) of consumers was highest at 312.5 g. Noodle intake also showed different patterns by ethnicity in which the "other" ethnic group consumed the most noodles with 366.1 g, followed by, in order, Hispanics with 318.7 g, Whites with 298.6 g, and Blacks with 289.5 g. After comparing food consumption by dividing the subjects into noodle consumers and non-consumers, the former was more likely to consume milk, fish, citrus fruits, tomatoes, and alcoholic beverages while the latter preferred meat, poultry, bread, and non-alcohol beverages.

Ramyen and Korean noodles (guksu) are popular foods in Korea and around the world. Since 1998, rice consumption in Korea has gradually decreased, whereas consumption of noodles has continuously increased. The purpose of this study is to assess the consumption of ramyen and Korean noodles of Koreans, using data from the Korean National Health and Nutrition Examination Survey (KNHANES) of 2007. Korean adults (>20) were selected to examine the associations between noodle consumption and food and nutrient intake and health status. SAS 9.1 and SUDAAN 9.1 were used for the data analysis. 10.3% of Korean adults consumed ramyen, and 15.4% consumed Korean noodles. The consumption of ramyen and Korean noodles were higher in men than in women, in lunch than in other meals, and in the lowest income quartile than the highest quartile. Ramyen and Korean noodle consumer groups consumed more grain products, seasonings, and oils than the non-consumer group. The noodle group showed significantly lower systolic blood pressure than the non-consumer group. The noodle groups showed lower rates of hypertension and metabolic syndrome than the non-consumer group. From these results, we conclude that ramyen and Korean noodles may have positive health effects. More studies on the association between noodles and the health of Koreans and those in other countries should be done in the future.

Nutritional researchers world-wide are using large-scale sample survey methods to study nutritional health epidemiology and services utilization in general, non-clinical populations. This article provides a review of important statistical methods and software that apply to descriptive and multivariate analysis of data collected in sample surveys, such as national health and nutrition examination survey. A comparative data analysis of the Korea National Health and Nutrition Examination Survey (KNHANES) was used to illustrate analytical procedures and design effects for survey estimates of population statistics, model parameters, and test statistics. This article focused on the following points, method of approach to analyze of the sample survey data, right software tools available to perform these analyses, and correct survey analysis methods important to interpretation of survey data. It addresses the question of approaches to analysis of complex sample survey data. The latest developments in software tools for analysis of complex sample survey data are covered, and empirical examples are presented that illustrate the impact of survey sample design effects on the parameter estimates, test statistics, and significance probabilities (p values) for univariate and multivariate analyses.
