  • This study was performed to establish an analytical method for the standardization of Angelicae Dahuricae Radix as a functional ingredient. We established six compounds including oxypeucedanin hydrate (1), byakangelcol (2), oxypeucedanin (3), imperatorin (4), phellopterin (5) and isoimperatorin (6) as marker compounds of Angelicae Dahuricae Radix. An analytical method using Ultra Performance Liquid Chromatography (UPLC) was established and validated for marker compounds of Angelicae Dahuricae Radix. The specificity was confirmed by the chromatogram from UPLC and the value of coefficient determination was also higher than 0.999, indicating high linearity. The relative standard deviation (RSD) and recovery of marker compounds were less than 5% and in the range of 90- 110%, respectively, which means that this method has high accuracy and precision. Therefore, this analytical method could be used as basic data for the development of functional ingredients for health functional food of Angelicae Dahuricae Radix.

  • Class components in a repository require exact information representation by reason of insufficiency of various visual information through search and extraction. In this paper, we have described syntax-analysis method and viewer facilities about class components. In the components analysis, we extracted class information which consists of class_names, methods, attributes, class inheritance relationship, and graphic information. viewer represents extracted class information and creates a new class. Also, it provides facilities of reuse, insertion, and deletion. Not only Viewer represents class hierarchy diagram, and shows detail information about each class, but also it creates new classes. In this paper, we implemented a Viewer using the components, inheritance, diagram information and process. And we enhanced understanding of programs through viewer, and supported prototype for class creation.

  • This paper analyzes the hazard related to train control, the functional requirements for atrain control system(TCS) and the automatic train protection(ATP) functional allocation that ensures the interoperability of a radio communications-based TCS. In addition, the interoperability can be obtained using wireless communications technology standards and standardized functional allocations of TCS performed on the wayside and onboard. Using this information, an integrated operating system for a rail network can be constructed. The functional allocations of TCS that support interoperability, require hazard analysis of TCS and definition of the system requirements. The hazard factors for a TCS are confirmed through setting the train safety space control and train speed limit excess. Furthermore, this paper determines the impact of the hazard factors on the TCS and, defines the functional requirements for the TCS subsystems and the ATP wayside and onboard functional allocations.

  • As of December 2013, 63 distance education training centers has been operating in the form of private, university affiliated and national/public centers. LMS is related to distance training quality as the system because distance education training centers are managing training by using LMS. In this paper, LMS functions of distance education training centers were analyzed to enhance the quality of distance training. In results of the analysis, it is showed 70.07%, 72.09% and 70.41% that implementation ratio of necessary LMS functions for trainee, manager and tutor. Functions of the lowest implementation ratio were "training support" of trainee mode, "statistics management" of manager mode and "communication" of tutor mode. The results of this paper will be helped to improve LMS for effective distance training of distance education training centers.

  • The purpose of this study was to systematically review about randomized controlled trials the characteristics and effect of cognitive function intervention for patient with dementia. We searched studies published from January 2010 to June 2021 in 5 databases. A total 1,104 studies were found and included 27 studies in final analysis. Methodological quality was assessment with the Cochrane's RoB(risk of bias) tool. Mini-Mental State Examination(MMSE) was the most used as the assessment tool for identifying the cognitive function. Cognitive function intervention were exercise, art, cognitive stimulation, reminiscence, music, multimodal cognitive rehabilitation, virtual reality, horticultural, computerized cognitive training, intentional snoezelen, beauty, cooking, korean traditional familiarity program. Most of the intervention except exercise 2, virtual reality 1, beauty 1 were effective in improving cognitive function. This study provided a clinical evidence for planning and implementing intervention for cognitive function intervention. In the future, various intervention studies suitable for the characteristics of dementia should be conducted by improving the quality of research methods.

  • This study was conducted to analyze the mediating effect of health status and the moderating effect of economic activity in the relationship between depression and cognitive function of the elderly. For this, the data of 2017 National survey of Older Koreans that was collected all over country by Korea Institute for Health and Social Affairs were analyzed using Structural Equation Model for statistical analysis method. The results are as follows. First, the elderly's depression was found to have a negative effect on cognitive function and health status. Second, the health status of the elderly was found to have a positive effect on cognitive function. Third, a significant mediating effect of health status was founded in the relationship between depression and cognitive function. Fourth, the moderating effect of the elderly's economic activity was found in the path through which depression affects health status and health status affects cognitive function. Based on these research results, implications of social welfare were suggested.

  • This study investigated and analyzed the symptoms of urinary incontinence and the wearing status, purchase status, and preference for urinary incontinence products in women in their 50s and older. When purchasing urinary incontinence pads and panty, waterproof function and absorption speed were recognized as important. In urinary incontinence products, the most common function was to prevent leakage, and the preferred color was skin. When the number of urinary incontinence was high, the absorption function was considered important. Size or fit was important when the amount of urinary incontinence was small, but waterproof function was found to be important when the amount of urinary incontinence increased. It was hoped that a function to prevent leakage would be added when the incidence of urinary incontinence and the amount of urinary incontinence were high, and a panty-type pad was preferred. It was analyzed that the higher the number of births, the higher the amount of urinary incontinence, and the more frequent symptoms of urinary incontinence appeared. t was found that the earlier menopause, the higher the amount of urinary incontinence.
