1. Introduction The new computing era started with the various computer technologies and services having been used in communication and automation area since 1980's. We call that era information technology(IT) era. In such era, especially communication plays very important roles in every aspect. So Schoderbek named that era the ege of c2. Therefore, communition became widely used in organizations. Now the majority of organizations have computer-aided communication capabilities that facilitate access to people and information, both within and outside organization. So one objective of this study is to assess the effects of these changes in data communication on decision making. Decision making is the essence of management and is too important to organizational success. This dissertation has three basic objectives: 1)to clarify the concept of data communication, who influences on decision making, and the concept of decision types, managerial and operational, may be affected differently by data communication 2)to investigate whether the effects of data communication upon decision making may be organizational variables. 3)to verify that business and decision types may affect different impact on decision making.2. Hypotheses Four attributes are selected to make hypotheses from the information attributes presented by famous scholars. They are as follows. ①effectiveness ②routinization ③communication easiness ④timeliness Hypotheses are developed according to these attributes, which are chosen from the literature study and theory H1 : Data communication is positively related to the effectiveness of DM H2 : Data communication is positively related to the routinization of DM H3 : Data communication is positively related to the communication easiness of DM H4 : Data communication is positively related to the timeliness of information for DM3. Methodology After pilot study, data are collected from the decision makers in 200 companies located at Seoul and the metropolitan area. A random sample of 174 employees sent back their questionnaires(response rate of 87%). Among them, 151 questionnaires was useful to the analysis of this study(useful rate of 75.5%).4. Conclusion and Discussion Among four proposed hypotheses, all hypotheses are fully supported. They are as follows. 1)effectiveness 2)routinization 3)communication easiness 4)timeliness. So, first objective of this study is proved. Namely, to clarify that the effects of data communication upon DM is fully supported. But they are different from the decision types. Second one is not apparently verfied. i.e. the effect of data communication on the decision variables is not moderated by organizational variables. Third is inspected. The effects of data communication differs from the industry and decision types evidently. This study has many limitations to generalize the statistical results. Since the definition of data communication has broad meanings in reality. So allare not contained in this research. Another restrict in this study is like this. Decision types are usually divided into three types-operational, managerial, strategic DM. But in this study, strategic DM is left out.

Stroke is a major cause of death and disorder, and diabetes mellitus (DM) is a significant risk factor of stroke. This study examined the importance of target blood pressure (<140/<90 mmHg) management in patients with DM. Based on the data of the 6th National Health and Nutrition Examination Survey, a total of 16,389 patients aged 18 to under 80 were assessed through regression analysis to estimate the risk of stroke through blood pressure control. The prevalence of stroke according to the presence or absence of DM was higher in the diabetic group, and a longer duration of DM indicated a higher risk of hypertension and stroke. The hazard ratio of stroke was lower in the maintenance group (0.57) of target blood pressure (<140/<90 mmHg) compared to the high blood pressure group(>140/>90 mmHg). Despite the accompanying treatment for DM and hypertension, the frequency of hypertension increased, and the prevalence of stroke increased after five years of DM. Hence, effective blood pressure management at this time is important. The risk of stroke should be reduced by continuously managing blood pressure in DM.

The purpose of this study was to investigate the association of obesity with medical care use and costs according to overall diseases, cerebrovascular diseases (CVD), ischemic heart disease (IHD), hypertension (HTN) and diabetes mellitus (DM). The final sample was a group of persons who were free of diseases mentioned above and were not underweight. Their baseline screening program data and health insurance contribution data were connected with a 7-year medical claim database. The participants were classified according to their baseline BMI into normal, overweight, obese, and severely obese groups. Given the disease type, the total costs of DM showed the largest difference in each obesity group in both males and females. Also, the pharmacy costs for DM were more relevant than any other type of service to the obesity level. Considering the high prevalence of obesity and the relevantly increased medical care use and costs, there is a need for reduction in medical costs through obesity prevention efforts.

Digital manufacturing(DM) is the ability to describe every aspect of the design-to-manufacture process digitally-using tools that include digital design, CAD, office documents, PLM(Product Life-cycle Management) systems, analysis software, simulation, CAM software and so on. The major automotive companies are already deeply invested in DM with almost every process being digital rather than paper-based. But it has taken a long time for the digital process to mature into something usable and there have been some major barriers that have prevented from the DM becoming a reality. Thus many companies hesitate to make a decision of implementing the DM. This paper deals with a study investigating which factors are important for implementing the DM to industries successfully. The extended technology acceptance model (ETAM) is used as the relation model of cause and effect. The quality of hardware, the quality of software, the range of collaboration among companies and the preference of the user are defined as the external factors. Interview method is used for gathering input data, and the results are analyzed with SPSS. The results indicate that four external factors are effective on the successful implementation of DM, and the perceived usefulness is most important.

Purpose: This study aims to compare health status and health behavior among the hypertension group, the DM group, and the hypertension-DM group for aged clients of customized home visiting health care services. Methods: This study was conducted as cross-sectional research. The subjects of this study were 2,235 aged people over 65 living in J City. Data were collected using structured questionnaires and measurements. The collected data were analyzed using the SPSS/WIN 12.0 program, and descriptive statistics, $x^2$ test, t-test and ANOVA were used for the analyses. Results: BP and glucose control showed a significant difference among the groups. BMI and waist circumference were significantly higher in the hypertension-DM group than in the other groups. Stroke, arthritis, and perceived health status were significantly different among the three groups. Depression was high, but not significantly different among the groups. Smoking and drinking were not significantly different among the groups. Physical activity was very low, especially in the hypertension group. Medication was high, especially in the hypertension-DM group. Conclusion: It is necessary to consider care plans for the hypertension-DM group, and educate the group for care management.

BACKGROUND/OBJECTIVES: This study was aimed at examining the association between dietary flavanones intake and lipid profiles according to the presence of metabolic syndrome (MetS) in Korean women with type 2 diabetes mellitus (T2DM). SUBJECTS/METHODS: A cross-sectional analysis was performed among 502 female T2DM patients (non-MetS group; n = 129, MetS group; n = 373) who were recruited from the Huh's Diabetes Clinic in Seoul, Korea between 2005 and 2011. The dietary intake was assessed by a validated semi-quantitative food frequency questionnaire (FFQ) and the data was analyzed using the Computer Aided Nutritional Analysis program (CAN-Pro) version 4.0 software. The intake of flavanones was estimated on the basis of the flavonoid database. RESULTS: In the multiple linear regression analysis after adjustment for confounding factors, daily flavanones intake was negatively associated with CVD risk factors such as total cholesterol, LDL-cholesterol, and apoB and apoB/apoA1 ratio only in the MetS group but not in the non-MetS group. Multiple logistic regression analysis revealed that the odds ratio for a higher apoB/apoA1 ratio above the median (${\geq}0.74$) was significantly low in the $4^{th}$ quartile compared to that in the $1^{st}$ quartile of dietary flavanones intake [OR: 0.477, 95% CI: 0.255-0.894, P for trend = 0.0377] in the MetS group. CONCLUSIONS: Dietary flavanones intake was inversely associated with the apoB/apoA1 ratio, suggesting a potential protective effect of flavanones against CVD in T2DM women with MetS.

Prader-Willi syndrome (PWS) often develops type 2 diabetes mellitus (T2DM) related to severe obesity. The prevalence of T2DM in adults with PWS (7-20%) exceeds greatly the prevalence in the general population (5-7%). It is uncommon for pre-pubertal children with PWS to develop overt diabetes or glucose intolerance. GH therapy and genotype did not influence the development of altered glucose metabolism. It has been assumed that T2DM in PWS develops as a consequence of morbid obesity and concomitant insulin resistance. However recent studies suggest the relationship between morbid obesity and T2DM development is more complex and appears to differ in PWS subjects compared to non-PWS subjects. PWS patients had relatively lower fasting insulin levels and increased adiponectin levels compared with BMI-matched obese control despite of similar levels of leptin. So PWS children may be protected to some extent form of obesity-associated insulin resistance. Although there's no data, it seems logical to approach diabetes management including weight loss and increased exercise, using similar pharmacological agents as with non-PWS obesity-related diabetes such as metformin or thiazolidinedione, with the introduction of insulin as required. On the other hand, several recent T2DM in PWS case reports suggest favorable outcomes using Glucagon-like peptide 1 (GLP-1) analog with regard to ghrelin reduction, control of glucose and appetite, weight loss and pre-prandial insulin secretion. The role of GLP-1 agonist therapy is promising, but has not yet been fully elucidated.

Purpose: To analyze the effects of customized home visiting health services on the health and health behaviors of clients with hypertension (n=107) and diabetes mellitus (DM: n=67). Methods: A one group pre and post-test research design was used. The subjects were registered in a customized 8-week, interventional, home visiting health services available in Daegu. Data was collected from November 17, 2008 to January 23, 2009. Analyses involved descriptive statistics, $x^2$ test and paired t-test. Result: Hypertension control rate was improved 25.2% and DM control rate was improved 3.0%. There were significantly beneficial hypertension-related differences in BP, health belief, health knowledge and health behaviors including performance of 10 min of moderate exercise, diet, BP monitoring and medication. Significantly beneficial DM-related changes included glucose, health belief, health knowledge and health behaviors including performance of 10 min of moderate exercise and glucose monitoring. But there were no significant hypertension-related differences in health belief (barrier) and health behavior including drinking and exercise length/frequency. Also, no significant DM-related differences were evident in health belief (barrier) and health behaviors including drinking, smoking, exercise length/frequency, diet and medication. Conclusion: Customized home visiting health service can provide effective, but not complete. Whether these benefits are maintained in the longer term is unknown.

The purpose of this study was to examine the factors affecting quality of life among elderly people with type 2 diabetes mellitus (DM) in a community. The design of this study was an exploratory survey. The subjects were 268 adults aged over 65 years with DM in a community. The data were collected from July to October, 2011 and analyzed by descriptive statistics, Pearson's correlation coefficient, and stepwise multiple regression by using SPSS/WIN 20.0 program. The quality of life was positively associated with self care behavior (r=.226, p<.001), self-efficacy (r=.323, p<.001), and social support (r=.345, p<.001). However, quality of life had moderately negative correlation with depression (r=-.445, p<.001). Among the variables, depression, social support, and self-efficacy were explanatory factors accounting for 23.9% of quality of life. These findings suggest that depression and self-efficacy are important factors affecting quality of life in the elderly with DM and it can be improved by strengthening social support.
