The purpose of this study was to investigate the effect of combined exercise on lung function, blood vitamin D, calcium and bone metabolism hormones in elderly women who are over 65 years by dividing them into a combined exercise group(n=13), control group(n=17). The combined exercise program included 60-minutes sessions 3times each week. Aerobic exercise intensity was 40-50%HRR(RPE 12-13) for 1-4 week, 50-60%HRR(RPE 13-14) for 5-8 week, and 60-70%HRR(RPE 14-15) for 9-12 week and resistance exercise intensity was set at OMNI-RES 3-4 for 1-4 week, OMNI-RES 5-6 for 5-8 week, OMNI-RES 7-8 for 9-12 week. As a result, lung function indicated that FEV₁ showed an interaction effect between group and time and FVC/FEV₁ levels significantly increased in combined exercise group. Blood vitamin D showed an interaction effect between group and time, also, significantly increased in combined exercise group and control group. Calcium showed an interaction effect between group and time, and significantly decreased in control group. Bone metabolism hormones indicated that both calcitonin and osteocalcin showed an interaction effect between group and time, osteocalcin significantly decreased in control group. For the following this conclusion, elderly women can be improved their lung function through 12 weeks combined exercise and also mitigate the blood vitamin D but there was no meaningful results of calcium and bone metabolism hormones.

We propose a Korean compound noun semantic tagging system using statistical compound noun decomposition and semantic relation information extracted from a lexical semantic network(U-WIN) and dictionary definitions. The system consists of three phases including compound noun decomposition, semantic constraint, and semantic tagging. In compound noun decomposition, best candidates are selected using noun location frequencies extracted from a Sejong corpus, and re-decomposes noun for semantic constraint and restores foreign nouns. The semantic constraints phase finds possible semantic combinations by using origin information in dictionary and Naive Bayes Classifier, in order to decrease the computation time and increase the accuracy of semantic tagging. The semantic tagging phase calculates the semantic similarity between decomposed nouns and decides the semantic tags. We have constructed 40,717 experimental compound nouns data set from Standard Korean Language Dictionary, which consists of more than 3 characters and is semantically tagged. From the experiments, the accuracy of compound noun decomposition is 99.26%, and the accuracy of semantic tagging is 95.38% respectively.

SDO(Software Development Outsourcing) projects have been consistently increasing and expanding but also have many failures. In order to improve SDO performance, the factors affecting SDO performance are investigated in this study. SDO has relational risk as well as performance risk in nature, and the factors affecting the SDO performance caused by these mixed risks are drawn from the prior studies. With field survey targeted client IS personnel who experienced SDO, 214 survey questionnaires are collected and analyzed. Research results show that vendor power, client requirements certainty, goal clarity and goal alignment affect the SDO performance. However, vendor knowledge and client knowledge do not have much effect on SDO performance. The results of this study can be effectively utilized to decrease the failures of SDO and increase the possibility of success.
