  • Companies widely use survey to identify customer requirements, but the survey has some problems. First of all, the response is passive due to pre-designed questionnaire by companies which are the surveyor. Second, the surveyor needs to have good preliminary knowledge to improve the quality of the survey. On the other hand, text mining is an excellent way to compensate for the limitations of surveys. Recently, the importance of online review is steadily grown, and the enormous amount of text data has increased as Internet usage higher. Also, a technique to extract high-quality information from text data called Text Mining is improving. However, previous studies tend to focus on improving the accuracy of individual analytics techniques. This study proposes the methodology by combining several text mining techniques and has mainly three contributions. Firstly, able to extract information from text data without a preliminary design of the surveyor. Secondly, no need for prior knowledge to extract information. Lastly, this method provides quantitative sentiment score that can be used in decision-making.

  • 본 연구는 가정과교육의 성격과 정체성, 그리고 미래 방향을 탐구하는데 활용할 수 있는 기초자료를 제공하기 위하여, 가정교과에 대한 개인의 주관적 인식인 교과의 이미지를 유형화하여 제시하고자 하였다. 이를 위하여 개인의 주관적 인식 경향을 객관화하여 유형화할 수 있는 질적 연구방법인 Q방법론을 활용하여 예비 가정교사를 대상으로 가정과교과의 이미지를 유형화 하였다. 그 결과 가정교과에 대한 이미지의 유형을 총 5가지로 분류할 수 있었다. 구체적인 연구결과는 다음과 같다. 첫 번째 유형은 '사회의 적응을 위한 교과'로서 인식하는 집단이다. 이 유형은 가정교과를 통해 개인이 사회의 성숙된 구성원으로 자립할 수 있도록 하는 기본적인 능력이 길러지며, 미래의 변화에 적응할 수 있는 능력이 가정교과를 통해 완성될 수 있다고 인식하는 집단이다. 두 번째 유형은 '편견으로 소외된 교과'로서 인식하는 집단이다. 이 유형은 가정교과는 다른 교과와 비교할 때 입시와 관련이 적고 취업과도 직접적인 관련이 없는 것으로 인식하고 있으며, 아직도 가정주부들의 일을 배우는 교과로 인식하는 사회적 편견으로 인해 상처를 많이 받는 교과로 생각하는 집단이다. 세 번째 유형은 '삶의 기본요소를 알려주는 교과'로 인식하는 집단이다. 가정교과가 삶의 기본적인 요소를 가르쳐 주는 교과로 다양한 경험의 습득, 바르게 살아갈 수 있는 능력 등과 관련된 교과로 인식하는 집단으로, 인간생활의 거의 모든 면을 다루는 교과로 생활과 밀접한 관계가 있는 교과로 생각하는 집단이다. 네 번째 유형은 '가정생활을 강조하는 교과'로 인식하는 집단이다. 이 집단의 경우 가정교과를 전통적으로 가정교과가 담당하고 있었던 가정생활 영위를 위한 기술과 능력을 배양하는 것으로 인식하고 있지만, 시대의 흐름에 맞추어 이러한 가정생활의 기술이 여성에게만 한정된 것이 아니라 남성에게도 필요한 분야라는 사실을 강조하고 있다. 다섯 번째 유형은 '개인적 성숙을 강조하는 교과'로 생각하는 집단이다. 이 유형에 속하는 집단은 가정교과가 개인의 성숙의 바탕이 되는 기본적인 자질을 배양하는 경향이 있으며, 기본적인 인격수양과 바른 인성 그리고 위기대처 능력까지를 포함한 개인발달의 기초가 되는 여러 가지 능력을 키우는 교과로 생각하고 있는 것으로 나타났다.

  • Introduction: The aim of this study protocol is to share and disclose the methodology used to develop an evidence-based clinical practice guideline (CPG) of therapeutic interventions used in Korean medicine for patients with stroke. Methods: The CPG development process will consist of two phases. In phase I, a development committee will be established, and they will decide the key questions to be answered. A systematic review and meta-analysis will be performed to answer these key questions by searching relevant randomized controlled trials and systematic reviews. Draft recommendations will be developed according to the evidence level and recommendation grades primarily determined using the GRADE methodology. Panels comprised of external experts will be formed, and surveys and a face-to-face meeting will be conducted to reach a consensus on the recommendations. A preliminary guideline will be created after final review by the development committee. In phase II, we will conduct clinical trials and economic analysis to supplement the lack of evidence found in the phase I. Conclusion: The CPG is expected to help doctors practicing Korean medicine in clinics or hospitals with making decisions based on the most reliable evidence, ultimately leading to the provision of optimal care for patients with stroke.

  • Purpose: The purpose of this study was to develop and validate of a knowledge scale for lymphedema in patients with breast cancer. Methods: 34 preliminary items were made according to literature review, then verified content validity, construct validity, and reliability of the scale. 28 items among them were confirmed through content analysis by 4 experts. After a preliminary test, a survey for 156 breast cancer patients was performed for confirming construct validity and reliability. The data were analyzed using factor analysis, independent t-test, and KR-20. Results: This scale had 28 items consisting of 2 categories: prevention and self-care of lymphedema. Construct validity was confirmed by known-group technique because there were some categories consisted of just one or two items, and some mismatches between categories and items in factor analysis. Women who were educated about lymphedema scored significantly higher than women who had not (t=-3.92, p<.001). Reliability was appropriate (KR-20=.81). A percentage of correct answers was 74.6%, but it was from 31.8% to 96.1%. Conclusion: The study shows that this scale is reliable and valid to measure the knowledge of lymphedema. This scale can be effective to assess and educate the patients with breast cancer.

  • Purpose: The purpose of this study was to develop a scale of free nursing home adjustment for the elderly in Korea. Method: The developmental processes were construction of a conceptual framework, development of preliminary items, verification of content validity, twice data gathering, verification of construct validity, and reliability of final items. The first 53 preliminary items were obtained through review of literatures about nursing home adjustment and in depth interviews with 5 staffs of nursing home. These items were reviewed by five specialists for content validity and 39 items were chosen. The first data was collected from 107 elderly residing in 3 nursing homes and the second survey was from 147 residents who were living in five nursing homes. Finally this data was analyzed for construct validity and reliability. Result: There were 23 final items which were sorted into 5 factors. The factors were identified as 'Relocation distress symptom'(8items), 'Making friends'(4items), 'Acceptance of new residence'(6items), 'Difficulty in group life'(3items), and 'Having self-worth'(2items). The cumulative percent of variance was 53.466%. The reliability of the scale, Cronbach's alpha was .837. Conclusion: The result of this study could be used for measuring nursing home adjustment of the elderly. However, for further validity and reliability, repeated researches are needed.

  • This paper presents a preliminary study of introduction of the Dempster-Shafer inexact reasoning method to the expert system for the power system design problem. A brief review of Dempster-Shafer theory of evidence is presented and development of an inference engine adopting the Dempster-Sharer theory is reported. Developed inference engine has a ability of handling both the confirming and disconfirming knowledge represented in the production rule, and has a general purpose application in the design and diagnosis problems. Its applicability has been tested on the problem of the protection scheme selection, one of the typical design problem and we believe, it has shown the feasibility of adoption of the inexact reasoning methodology into the design problem.

  • Purpose The purpose of this study is to clarify the conceptualizations of mandatory and reward that have come into focus in the definition of digital shadow work. And explore how users in a shared services environment view cost and coercion from the perspective of digital shadow work. Design/methodology/approach We conducted one-on-one interviews with 4 participants, with each interview being an average of 25 minutes. Based on literature review, stakeholder observation, and interviews on digital shadow work so far, very objective results can be derived through triangulation based on the basis of multiple sources. Findings According to the results of the preliminary study, there are some rewards for each type of digital shadow work, but time saving and service convenience are considered more than financial rewards. Unfair demands in determining whether to implement them in consideration of the difficulty and expected benefits of the demanding digital work can cause dissatisfaction with the service. Academic implications and future research directions are also discussed.
