The computing systems of today expanded business trade and distributed business process Internet. More and more systems are developed from components with exactly reusability, independency, and portability. Component based development is focused on advanced concepts rater than passive manipulation or source code in class library. The primary component construction in CBD. However, lead to an additional cost for reconstructing the new component with CBD model. It also difficult to serve component information with rapidly and exactly, which normalization model are not established, frequency user logging in Web caused overload. A lot of difficult issues and aspects of Component Based Development have to be investigated to develop good component-based products. There is no established normalization model which will guarantee a proper treatment of components. This paper elaborates on some of those aspects of web application to adapt user requirement with exactly and rapidly. Distributed components in this paper are used in the most tiny size on network and suggest the network-addressable interface based on business domain. We also discuss the internal and external specifications for grasping component internal and external relations of user requirements to be analyzed. The specifications are stored on Servlets after dividing the information between session and entity as an EJB (Enterprise JavaBeans) that are reusable unit size in business domain. The reusable units are used in business component through query to get business component. As a major contribution, we propose a systems model for registration, auto-arrange, search, test, and download component, which covers component reusability and component customization.

Objectives This study is aimed to develop a Clinical Practice Guideline (CPG) on acupuncture treatment for the stroke patients with Post-stroke Urinary Incontinence(PSUI). Methods Experts committee, consisting of stroke or methodology specialists, searched Medline, EMBASE, Cochrane Library, China National Knowledge Infrastructure, and 19 Korean medicine journals. The search terms were selected to screen the randomized controlled trials (RCTs) or systematic reviews for the effectiveness of acupuncture on PSUI, compared with placebo or conventional group. Levels of evidence and grades of recommendations were appraised based on Recommendations for Development of Clinical Practice Guideline in Korean Medicine. Results & Conclusions 8 RCT were included to build the CPG. There was a strong evidence to support the effectiveness of acupuncture treatment for PSUI. The moderate evidence was presented that over 3 times a week of the acupuncture should be performed over 4 weeks on the acupoints, such as BL23, CV3, SP6, CV4, CV6, ST28, BL28, BL32, GV20, BL22, GV4 or ST36, for 15-30 minutes. 1-150 Hz frequency is suggested if electro-acupuncture treatments is performed with. It was also suggested that the procedure should begin at the acute stage just after the vital signs of the patients are stabilized. There was a moderate evidence to support safety of acupuncture treatment for PSUI. We recommend acu-points of constitutional acupuncture for Sasangin on the healthy side.

Purpose: Functional dyspepsia (FD) is a chronic syndrome accompanied by repetitive digestive symptoms that appear in the upper gastrointestinal tract and are not caused by specific diseases. Psychological symptoms like anxiety, depression, insomnia, and somatization are frequently observed in FD. The purpose of this study was to review the effect of herbal medicine on the psychological symptoms that accompany FD. Methods: Database search (PubMed, EMBASE, KISS, Kmbase, KoreanMed, NDSL, OASIS, CNKI) was performed on February 24, 2021; a total of 1825 studies were searched. After the screening, 22 studies were included. Results: The studies were assessed by Cochrane RoB 2 and sorted into a table according to psychological symptoms. Meta-analysis was performed to estimate the effect of herbal medicine. Twenty of the twenty-two studies reported that herbal medicine was significantly more effective than the control group. Only three of the studies did not have a high risk of bias. Conclusion: Herbal medicine was significantly effective with or without Western medicine and had fewer adverse effects. Severe adverse effect was not reported. Psychological symptoms in FD affect onset and duration of FD, and some FD patients want to be treated for their anxiety before other symptoms. Reliable information about treatment for the psychological symptoms of FD is lacking. We reviewed the effect of herbal medicine treatment in this study, the results of which could be selected for primary or secondary treatment for FD.

In this work, we develop a Korean dependency parser based on a stack-pointer network that consists of a pointer network and an internal stack. The parser has an encoder and decoder and builds a dependency tree for an input sentence in a depth-first manner. The encoder of the parser encodes an input sentence, and the decoder selects a child for the word at the top of the stack at each step. Since the parser has the internal stack where a search path is stored, the parser can utilize information of previously derived subtrees when selecting a child node. Previous studies used only a grandparent and the most recently visited sibling without considering a subtree structure. In this paper, we introduce graph attention networks that can represent a previously derived subtree. Then we modify our parser based on the stack-pointer network to utilize subtree information produced by the graph attention networks. After training the dependency parser using Sejong and Everyone's corpus, we evaluate the parser's performance. Experimental results show that the proposed parser achieves better performance than the previous approaches at sentence-level accuracies when adopting 2-depth graph attention networks.

Purpose: The standard tool for the pattern identification is used for identifying patterns in patients using a questionnaire. The purpose of this study is to reorganize the standard tool for the pattern identification of gastroesophageal reflux disease (GERD) developed in 2017 and to analyze the reliability and validity of the standard tool for pattern identification by applying it to GERD patients. Methods: To reorganize the standard tool for the pattern identification of GERD developed in the previous study, we searched the literature in the main databases, OASIS (Oriental Medicine Advanced Searching Integrated System) and CNKI (China National Knowledge Infrastructure). We added the search results to the data used in the previous study and went through the reorganizing courses, such as evaluating the validity of the translation, the Delphi technique, and a small survey. After reorganization, the patients who visited the Kyunghee University Korean Medicine Center for GERD symptoms were provided the questionnaire, including the reorganized standard tool for pattern identification. We analyzed the survey results to evaluate their reliability and validity. Results: Fifty patients completed the questionnaire. Reliability analysis results showed a pattern identification match rate of 86%, Cronbach's α coefficient of 0.834, and intraclass correlation coefficient of 0.907. The Mann - Whitney U test and logistic regression were implemented to check the relations between the survey questions and pattern identification results; the Pearson correlation, compared with other scales, showed a moderate score. Conclusion: We reorganized the standard tool for the pattern identification of GERD to be updated on current issues and so that it is easily used. The analysis results of the questionnaire showed that the reorganized standard tool had high reliability and moderate validity.

Objective : This study aimed to develop a Korean version of the HLS-EU-Q47 that deals with the concept of health literacy based on the understanding, apply/use, process/appraisal, and access/obtain to health information. The purpose of this study is to confirm the level of comprehensive health literacy of the elderly in Korea using this tool. Methods : After going through the Korean interpretation process of HLS-EU-Q47, the items were confirmed through content validity verification by experts. The completed Korean-HLS-EU-Q47 (K-HLS-EU-Q47) was applied to 254 elderly people in the local community to analyze the degree of internal consistency and reliability. Furthermore, a comparative analysis based on the general variables was conducted. Results : The internal consistency of this tool for the elderly yielded Cronbach's 𝛼 of .81~.91, indicating a high level of reliability. There was a difference in health literacy according to sex and age based on general characteristics. Men had higher health literacy than women, and with increasing age, health literacy decreased. Conclusion : In this study, the K-HLS-EU-Q47 was developed to assess the comprehensive health literacy level of the elderly in Korea. It is expected that the search for ways to maintain a healthier life for the elderly through understanding the health literacy levels of the elderly using the results of this study will become more active.

This paper provides a comprehensive study of optimum design of a helicopter tailrotor driveshaft made of the flexible matrix composites (FMCs). Since the driveshaft transmits power while subjected to large bending deformation due to aerodynamic loadings, the FMCs can be ideal for enhancing the drivetrain performance by absorbing the lateral deformation without shaft segmentation. However, the increased lateral flexibility and high internal damping of the FMCs may induce whirling instability at supercritical operating conditions. Thus, the purpose of optimization in this paper is to find a set of tailored FMC parameters that compromise between the lateral flexibility and the whirling stability while satisfying several criteria such as torsional buckling safety and the maximum shaft temperature at steadystate conditions. At first, the drivetrain was modeled based on the finite element method and the classical laminate theory with complex modulus approach. Then, an objective function was defined as a combination of an allowable bending deformation and external damping and a genetic algorithm was applied to search for an optimum set with respect to ply angles and stack sequences. Results show that an optimum laminate consists of two groups of layers: (i) one has ply angles well below 45$^{\circ}$ and the other far above 45$^{\circ}$ and (ii) the number of layers with low ply angles is much bigger than that with high ply angles. It is also found that a thick FMC shaft is desirable for both lateral flexibility and whirling stability. The genetic algorithm was effective in converging to several local optimums, whose laminates exhibit similar patterns as mentioned above.

This paper presents the technique separating objects on the single frame image from the background using region segmentation technique based on active contour. Active contour is to extract contours of objects from the image, which is set to have multi-search starting point to extract each objects contours for multi-object segmentation. Initial rough object segments are generated from binary-coded image using object specific contour information, and then the hole filling is performed to compensate internal segmentation caused by the change of inner object hole area and pixels. This procedure complements the problems caused by the noise from the region segmentation and the errors of segmentation near by the contour. The proposed method and conventional method is compared to verify the superiority of the proposed method.

Objectives: The purpose of this study was to examine clinical studies on the treatment of dysmenorrhea treatments and analyze the results to provide sufficient evidence to provide adequate evidence of the efficacy of the ear-acupuncture treatment on dysmenorrhea patients. Methods: The search for foreign papers used 'Pubmed', a research engine in the America National Library of Medicine. Used searching terms were 'dysmenorrhea' and 'menstrual pain' in all cases. And among these studies, we searched by using key word 'auricular acupuncture' or 'ear acupuncture' or 'auricular acupressure' or 'ear acupressure'. Results: Overall 53 studies, 7 studies were finally selected to this study. There was 1 controlled study, 3 clinical trials, and 3 randomized-control studies. About acupoints in study, the endocrine was used in all 7 papers. Internal genitals, shenmen, sympathesis, kidney, liver were used in 4 papers, central rim, hypo-cortex, uterus were used in 2 papers, central of cymba auriculae was used in 2 paper. In 4 papers, the effect of ear acupuncture treatment was effective in relieving menstrual pain. Moreover, we can see that ear acupuncture therapy was effective in reducing menstrual pain than in oriental herb medicine. Conclusions: As a result of the 7 papers, we found that patients with menstrual pain decreased after ear acupuncture therapy. However, there was little research and it was limited to achieving the results of the analysis. A vigorous clinical study should be conducted to demonstrate the efficacy of ear acupuncture therapy and standardize treatment methods.

Finance Companies are operating a security solution such as E-DRM(Enterprise-Digital Right Management), Personal information search, DLP(Data Loss Prevention), Security of printed paper, Internet network separation system, Privacy monitoring system for privacy leakage prevention by insiders. However, privacy leakages are occurring continuously and it is difficult to the association analysis about relating to the company's internal and external distribution of private document. Because log system operated in the separate and independent security solutions. This paper propose a systematic chains that can correlatively analyze business systems and log among heterogeneous security solutions organically and consistently based on security documents. Also, we suggest methods of efficient detection for Life-Cycle management plan about security documents that are created in the personal computer or by individual through the business system and distribution channel tracking about security documents contained privacy.
