Along with the rapid development of the database technology, as well as the widespread application of the database management systems are more and more large. Now the data mining technology has already been applied in scientific research, financial investment, market marketing, insurance and medical health and so on, and obtains widespread application. We discuss data mining technology and analyze the questions of it. Therefore, the research in a new data mining method has important significance. Some literatures did not consider the differences between attributes, leading to redundancy when constructing concept lattices. The paper proposes a new method of uncertain data mining based on the concept lattice of connotation difference degree (c_diff). The method defines the two rules. The construction of a concept lattice can be accelerated by excluding attributes with poor discriminative power from the process. There is also a new technique of calculating c_diff, which does not scan the full database on each layer, therefore reducing the number of database scans. The experimental outcomes present that the proposed method can save considerable time and improve the accuracy of the data mining compared with U-Apriori algorithm.

Purpose: The purpose of this study was to find out the difference in the priority level of recognition for universal design application in public spaces by gender. Method: ANOVA(analysis of variance) and post-hoc test were conducted to determine the priority level of recognition and pattern for the disabled, non-disabled, and experts classified into males and females. Results: There was no gender difference in the comparison by sector for all males and females. However, in comparing of domains and facilities, women showed a higher level of recognition than men in the building sector and cross domain. When comparing space consumers and producers by dividing them into male and female groups, women showed a higher level of recognition than men in producers, but there was no gender difference between consumers. In comparison by sector, domain and facility, women producers also showed a higher level of recognition in the road sector, park and recreation sector, sidewalk domain, four-spaces in the park and recreation sector, and six-spaces in the building sector than men producers. Also, in the building sector, women producers and consumers showed a higher recognition level than men. Comparing the disabled, non-disabled people and experts by dividing them into male and female groups, in the case of non-disabled people and experts, women showed a higher level of recognition than men, while men showed a higher level of recognition than women in the disabled. In addition, there were differences in recognition patterns in many spaces and facilities by gender. Implications: This study is meaningful in comparing the differences in the priority level of recognition and patterns between men and women to apply universal design for people of all ages and both sexes.
Osteoporosis is defined as a pathologic condition in which there occurs no change in the chemical composition of the bone, while bone resorption is abnormally increased. This compares with osteogenesis, which leads to a decrease in the amount of bone. Though many varieties of therapies have been tried, no fully effective method has been found. Korean red ginseng is an important variety of Korean ginsengs and many studies have been performed to investigate its effectiveness. But there has been no report on red ginseng's effects on osteoporosis. The purpose of this study was to determine the clinical effects of Korean red ginseng on postmenopausal osteoporosis patients. The study was designed as a double-blind study. Group I consisted of 30 postmenopausal osteoporosis patients who were administered red ginseng extracts and 15 patients who were administered maltose capsules, were included in group II. The following results were obtained after one-year administration to both groups. 1. There were no significant differences in the degree of wedging, number of compression fractures in the vertebral body, trabeculations, and Cobb's angles between the experimental and control groups. 2. Even though bone mineral density increased in the lumbar spine, and decreased in the femur, there was no significant statistical difference. 3. The serum levels of parathyroid hormone (PTH), calcium, phosphate, and alkaline phosphates showed no difference between the two groups regardless of treatment. 4. Urine Deoxy-pyridinoline (DPYD) decreased in the red ginseng group while it increased in the maltose group, but statistically there was no significant difference between the two groups. 5. The clinical presentations showed no significant differences using Visual Analog Scale. 6. The specific complications related with the long-term use of red ginseng did not occur in all patients. In conclusion, there were no statistically significant differences in clinical presentations, biochemical, and radiological studies between the red gins eng and maltose groups. No definite effectiveness of red ginseng on patients with osteoporosis was found.
Purpose : The purpose of the present study is to report the effect of proprioception of ankle after kinesiotaping application on ankle. Method : This study has conducted to target 30 average adult subjects with no damage to the ankle joint (16 males and 14 females). The group is divided into experimental group and sham groups in random way. The subjects in the experimental group are applied taping kinesiology on ankle joint. The subjects in the sham group are applied a sham taping on the ankle joint which is not actually affected for real ankle joint problem. Each subjects in both groups has tree trials in plantarflexion, dorsiflexion, inversion, and eversion before and after application of the kinesiotaping or sham taping of the bare footed ankle. The outcome were determined from the difference between the target angle and the trial angle produced by the subject. Results : These results from the experiment shows that the experimental group compared to the difference in kinesiotaping angle values were significantly different from each dorsiflexion (DF), eversion (EV) (p<.05). Otherwise, in the sham group did not produce significant differences in any joint movement. In addition, when we compared between two groups (the experimental and sham groups), it did not show that there was significant differences. Conclusion : First, there is no significant difference between the sham group and kinesiotaping group after proprioceptive tests. Second, even though there is no significant outcome in statistical analysis, there is actual differences in the experiment. This result might be ceiling effect, and if the kinesiotaping were applied to actual ankle injury patients, this taping treatment could be very effective for curing this patient.
The objectives of this study are to research into the traditional costume succession in south and north korea, and to compare similarity and difference of kinds, names, drawing of Jegory. Conclusions are described as follows: 1. In sort of Jegory, south and north korea have same kind of Jegory according to traditional form. But in making method, south korea have pursued various style from traditional type to modern type, north korea have maintained just simple and practical basic style. 2. South and north korea have used same or similar names for the basic part of Jegory. But north korea has made new names for constructional needs, so many differences were shown in the name of details. 3. In drawing of Jegory, north korea has hold traditional method and then tried to seek for rational, scientific technique. Also, due to the influence of south korea that advanced in modern aesthetic, drawing of Jegory in north korea were changed to similar.
Purpose: The aim of this study was to compare with color reproducibility of the coating method and dipping method using a colour liquid. Methods: Two groups of square-shaped specimens ($10mm{\times}10mm$ in diameter, 1.5mm thickness) were prepared for analysis(n=15/group). The CM(Coating Method) group was fabricated as full zirconia specimens with the coating coloring method and Group DM(Dipping Method) was prepared as specimens of 0.7 mm-thick zirconia plate using the dipping coloring method and veneered with 0.8mm-thick porcelain. Color parameters were measured with ShadeEye $NCC^{(R)}$ spectrophotometer and color differences were calculated using the equation ${\Delta}E^*= \{({\Delta}L^*)^2+({\Delta}a^*)^2+({\Delta}b^*)^2\}^{1/2}$. Non-parametric statistical methods, the Mann-Whitney test, and the Kruskal-Wallis test were used to analyze the data. Type one error rate was set at 0.05. Results: Color difference values larger than 7 were observed between specimens with the coating method and the dipping method, which were detectable difference in a clinical setting. Conclusion: Cautious application of the coating coloring method in a clinical setting and further researches to standardize the coating method are needed.
Objectives: The purpose of this study was to examine the impact of Diagnosis-Related Group (DRG)-based payment on the length of stay and the number of outpatient visits after discharge in for patients who had undergone caesarean section. Methods: This study used the health insurance data of the patients in health care facilities that were paid by the Fee-For-Service (FFS) in 2001-2004, but they participated in the DRG payment system in 2005-2007. In order to examine the net effects of DRG payment, the Difference-In-Differences (DID) method was adopted to observe the difference in health care utilization before and after the participation in the DRG payment system. The dependent variables of the regression model were the length of stay and number of outpatient visits after discharge, and the explanatory variables included the characteristics of the patients and the health care facilities. Results: The length of stay in DRG-paid health care facilities was greater than that in the FFS-paid ones. Yet, DRG payment has no statistically significant effect on the number of outpatient visits after discharge. Conclusions: The results of this study that DRG payment was not effective in reducing the length of stay can be related to the nature of voluntary participation in the DRG system. Only those health care facilities that are already efficient in terms of the length of stay or that can benefit from the DRG payment may decide to participate in the program.
This paper aims to study regional difference in strawberry farming technology and its causal factors based on the survey of controlled strawberry farmers in three major strawberry cultivating regions, which are Nonsan county of Chungnam Province, Damyang County of Junnam Province and Guchang County of Kyungnam Province. There are differences in variety adoption, packaging and grading method which cause the farming income gap among these regions. Farmers of Guchang County, who adopt new variety Yeobong and packing system, raised highest gross receipts but ranked next to Damyang in terms of net income because of high packing cost. Farmers of Nonsan County earned lowest income because of poor quality and low price in spite of adopting packing cost saving method. Therefore, results of this study shows that successful farming technology depend on whether or not farmers adopt market oriented technology. It is suggested that direction of strawberry farming technology should focus on adopting new varieties which can contribute to increasing farmers' paid price and developing technology of reducing cost such as labor saving and packing machine.
