Objective: Various psychological factors influence the occurrence of tension-type headaches. The aim of this study is to compare the level of alexithymia between tension-type headache patients and normal controls. Methods: Sixty-six subjects with tension-type headaches and 59 controls were studied. The Beck Depression Inventory and Toronto Alexithymia Scale (TAS-20K) were administered to the tension-type headache group and TAS-20K to the normal control group. Results: Compared with normal controls, the tension-type headache group had significantly higher alexithymia scores. There was also significant association between the level of alexithymia and the severity of the depression in tension-type headache patients. Conclusions: These findings suggest that patients with tension-type headaches have difficulty in expressing their emotions. And in patients with tension-type headaches, the more alexithymic they are, the more depressive. 목 적 : 긴장성 두통은 병태생리가 아직 명확하게 밝혀지지 않았지만, 심리적인 요소가 중요한 역할을 하는 통증 증후군의 하나로 알려져 있다. 두통과 관련된 심리적 요소 중의 하나가 alexithymia이다. 본 연구에서는 긴장성 두통 환자에서의 alexithymia 정도를 정상대조군과 비교하였으며 우울정도와, alexithymia와의 연관성을 분석하였다. 방 법 : 만 18세 이상의 긴장성 두통 환자 66명을 대상으로, alexithymia의 정도와 우울감을 알아보기 위하여 TAS-20K와 BDI를 시행하였다. 정상대조군에서는 TAS-20K를 시행하였다. 결 과 : TAS-20K는 긴장성 두통 환자군에서 정상대조군에 비하여 유의하게 높은 수준을 보였다. 또한 TAS-20K의 점수와 BDI 점수는 유의한 정적인 상관관계를 나타냈다. 결 론 : 긴장성 두통 환자들은 정상대조군에 비하여 높은 alexithymia 수준을 보였다. 또한 Alexithymia의 수준은 우울감과 유의한 연관성을 가진다. 임상의들은 긴장성 두통 환자들의 치료적 접근에서 alexithymia, 우울증과 같은 심리적 요소의 고려가 필요할 것으로 사료된다.

KOSDAQ 시장의 관리종목 지정 탐지 모형 개발

The purpose of this research is to develop a detection model for companies designated as administrative issue in KOSDAQ market using financial data. Administration issue designates the companies with high potential for delisting, which gives them time to overcome the reasons for the delisting under certain restrictions of the Korean stock market. It acts as an alarm to inform investors and market participants of which companies are likely to be delisted and warns them to make safe investments. Despite this importance, there are relatively few studies on administration issues prediction model in comparison with the lots of studies on bankruptcy prediction model. Therefore, this study develops and verifies the detection model of the companies designated as administrative issue using financial data of KOSDAQ companies. In this study, logistic regression and decision tree are proposed as the data mining models for detecting administrative issues. According to the results of the analysis, the logistic regression model predicted the companies designated as administrative issue using three variables - ROE(Earnings before tax), Cash flows/Shareholder’s equity, and Asset turnover ratio, and its overall accuracy was 86% for the validation dataset. The decision tree (Classification and Regression Trees, CART) model applied the classification rules using Cash flows/Total assets and ROA(Net income), and the overall accuracy reached 87%. Implications of the financial indictors selected in our logistic regression and decision tree models are as follows. First, ROE(Earnings before tax) in the logistic detection model shows the profit and loss of the business segment that will continue without including the revenue and expenses of the discontinued business. Therefore, the weakening of the variable means that the competitiveness of the core business is weakened. If a large part of the profits is generated from one-off profit, it is very likely that the deterioration of business management is further intensified. As the ROE of a KOSDAQ company decreases significantly, it is highly likely that the company can be delisted. Second, cash flows to shareholder’s equity represents that the firm`s ability to generate cash flow under the condition that the financial condition of the subsidiary company is excluded. In other words, the weakening of the management capacity of the parent company, excluding the subsidiary`s competence, can be a main reason for the increase of the possibility of administrative issue designation. Third, low asset turnover ratio means that current assets and non-current assets are ineffectively used by corporation, or that asset investment by corporation is excessive. If the asset turnover ratio of a KOSDAQ-listed company decreases, it is necessary to examine in detail corporate activities from various perspectives such as weakening sales or increasing or decreasing inventories of company. Cash flow / total assets, a variable selected by the decision tree detection model, is a key indicator of the companys cash condition and its ability to generate cash from operating activities. Cash flow indicates whether a firm can perform its main activities(maintaining its operating ability, repaying debts, paying dividends and making new investments) without relying on external financial resources. Therefore, if the index of the variable is negative(-), it indicates the possibility that a company has serious problems in business activities. If the cash flow from operating activities of a specific company is smaller than the net profit, it means that the net profit has not been cashed, indicating that there is a serious problem in managing the trade receivables and inventory assets of the company. Therefore, it can be understood that as the cash flows / total assets decrease, the probability of administrative issue designation and the probability of delisting are increased. In summary, the logistic regression-based detectio

예술교육에서의 디지털 리터러시 활용방안 연구 - 상호 작용성을 중심으로 -

신동인(Shin, Dong In),박미리(Park, Mi Ri),이유정(Lee, Yu Jung),고민수(Ko, Min Soo),정소라(Jeong, So Ra) 한국연극예술치료학회 2020 연극예술치료연구 Vol.- No.12-1

본 연구는 예술교육 현장에서 상호 작용성 중심의 디지털 리터러시를 활용하는 방안을 모색하여 효과적인 예술교육이 가능한 수업 모델을 구축함으로써 문화예술교육 전문가의 역량 강화를 실천하는 것을 목표로 한다. 이러한 연구가 시의적절한 이유는 전 세계적인 코로나 팬데믹 현상으로 디지털 리터러시를 활용한 교육이 그 어느 때보다도 중요한 화두로 대두되었기 때문이다. 이 연구를 위하여 상호 작용성을 위한 디지털 리터러시와 예술교육의 개념을 알아보고 인간중심과 창의성, 융합과 통합 그리고 현실 감각 고취의 4가지로 된 교육 모델을 정립하였다. 또한, 실제로 수행되었던 비대면 온라인 수업의 형태를 살펴보고 예술 강사들의 디지털 리터러시 능력을 설문을 통해 검토하였으며, 상호 작용성 중심의 디지털 리터러시를 활용한 프로그램을 개발하여 수업을 진행한 다음 분석하였다. 이 과정에서 클라우스 슈밥(Klaus Schuwab)이 주장한 4차 산업혁명의 사회에서 필요한 4가지 덕목을 강화하기 위한 예술교육과 디지털 리터러시, 즉 정보의 처리 과정이 어떠한 관계로 이루어져야 하는지 알았고, 결과적으로 디지털 리터러시를 활용한 예술교육에서 발생하는 상호소통에 대하여 새로운 단계를 확인할 수 있었다. 학생은 일차적으로 디지털 콘텐츠를 수업 안에서 소비하는 소비자로서 강사와 학생 간, 학생과 학생 간, 학생과 콘텐츠 간의 활발한 상호소통을 경험하였다. 이 후, 수업 안에서 자신의 콘텐츠를 재생산하며 디지털 콘텐츠를 생산하는 생산자로 변화하고, 다시 그 콘텐츠를 수용하고 소비하는 형태로 상호 작용의 선 순환적 과정을 반복 경험하였다. 이러한 교육 환경을 조성하기 위해서는 문화예술교육 전문가의 역할이 가장 중요하며 예술 강사의 역량 강화를 위해서 정보 리터러시 능력을 기본으로 하되, 정보에 내재한 인문학적 배경 관련 교육이 제공될 때 효과적임을 알 수 있었다. This study aims to strengthen the competence of culture and arts education experts by exploring ways to utilize digital literacy centered on interactivity in the arts education field and establishing a teaching model that enables effective arts education. The reason this research is timely is that education using digital literacy has emerged as an important topic more than ever, due to the global Corona Pandemic. For this study, the concept of digital literacy and art education for interactivity was investigated, and an educational model consisting of human-centered and creativity, convergence and integration, and a sense of reality was established. Next, we looked at the form of non-face-to-face online classes that were actually conducted, and reviewed the digital literacy skills of art instructors through a questionnaire. and we developed a program that utilizes digital literacy centered on interactivity, conducted actual classes, then analyzed them. In this process, it was discovered that the four virtues claimed by Klaus Schuwab to be needed in the society of the Fourth Industrial Revolution could be developed through the stages of digital literacy. Through this, we found out which kind of relationship should be made between art education and digital literacy. Resultingly, a new stage could be identified for the interaction that occurs in art education using unique digital literacy. Students experienced active interactions between lecturers and students, students and students, and students and contents as consumers who primarily consume digital contents delivered by art lecturers in class. Then, reproduce one s own contents in the class, the process of virtuous cycle could be seen in the form of the students changing into a producer who produces digital contents and accepting and consuming the contents again. The role of arts education experts is the most important to create such an educational environment. In addition, it was found that it was effective when education related to the humanities background embedded in information was provided while prioritizing digital literacy skills as a basis for reinforcing the capabilities of art instructors.

소셜미디어상에서의 침묵의 나선효과: SNS 자기표현 성향을 중심으로

신동인(Dong-In Shin),곽기영(Kee-Young Kwahk) 한국경영학회 2019 經營學硏究 Vol.48 No.5

Based on the spiral of silence and impression management theory, this study drew the motivational factors of SNS users opinion for social discourse and examined the processes by which individuals make social voices or become silent in social media according to the climate of opinion. This study suggested perceived opinion support, fear of negative evaluation, and SNS self-presentation tendency as motive factors of opinion expression. To verify this research model, data were collected from adults using SNS in Korea, and we conducted analysis by PLS (Partial Least Square) technique. The empirical analysis results revealed that the perceived opinion support had a negative effect on the fear of negative evaluation and the fear of negative evaluation showed negative influence on the willingness to speak out. On the other hand, unlike the hypothesis presented in this study, the fear of negative evaluation showed positive influence on SNS self-presentation tendency. Finally, SNS self-presentation tendency had a positive influence on willingness to speak out. As a result, there was a competitive mediation in which the sign of the direct path leading to the willingness to speak out and the sign of the indirect path through SNS self-presentation tendency were opposite to each other. Further analysis revealed that the SNS self-presentation tendency acted as a suppression variable in the structural model. As the SNS self-presentation tendency variable was included and controlled in the structural model, the effect of the direct path from the fear of negative evaluation to the willingness to speak out was strengthened. This study found a theoretical limitation that had been overlooked in the spiral of silence theory and suggested a new theoretical framework to reveal the process of public opinion formation using theoretical combination with impression management theory. Furthermore, we applied this to the social media environment and empirically verified the specific causal mechanism of the individual opinion process.

Based on the spiral of silence theory, this study drew the motivational factors of SNS users` opinions on social discourse, and examined the processes by which individuals make social voices or become silent in social media according to the climate of opinion. This study suggested perceived opinion support, fear of negative evaluation, self-censorship and self-monitoring as motive factors of opinion expression, and examined the differences in the effect of self-censorship and self-monitoring on willingness to speak out. To verify this research model, data were collected from adults using SNS in Korea, and we conducted analysis by PLS(Partial Least Square) technique. The empirical analysis results revealed that the perceived opinion support had a negative effect on the fear of negative evaluation and the fear of negative evaluation showed negative influence on the willingness to speak out. In addition, fear of negative evaluation showed a positive impact on self-censorship and self-monitoring, but the path of each of the two variables to the willingness to speak out showed different results—the former showed a negative impact, and the latter showed positive effects. This study has found a theoretical limitation that has been overlooked in the spiral of silence theory and suggests a new theoretical framework to reveal the process of public opinion formation. Furthermore, we applied this to the social media environment and empirically verified the specific causal mechanism of the individual opinion process.

신동인 ( Dong-in Shin ),구동현 ( Dong-hyun Gu ),김강년 ( Kang-nyeon Kim ),김준건,김민영,이상원 ( Sang-won Lee ) 한국정보처리학회 2013 한국정보처리학회 학술대회논문집 Vol.20 No.1

모바일 환경에서의 인터넷 서비스 이용 특히 스마트 폰을 이용한 서비스에서는 사용하는 트래픽의 양에 따라 요금이 달라지고 또한 사용자가 체감하는 인터넷 속도역시 달라지기 때문에 많은 서비스 제공자들은 사용자에게 최소한의 트래픽으로 많은 정보를 제공하기 위해 노력을 하고 있다. 하지만 이러한 노력들에도 불구하고 서버에서 제공하는 파일에 수정이 가해졌을 경우 비록 수정된 양이 적더라도 해당 파일의 전체를 다운로드 해야 하는 문제점을 가지고 있었다. 이에 본 논문에서는 해당 문제점을 해결하여 네트워크 트래픽을 최소화시킴으로 사용자의 재정적 부담을 줄이고 체감 속도를 높이기 위한 기법으로 diff-patch 방식을 제안한다. 해당 기법을 안드로이드 환경에서 구현하고 실제 사용되는 자바스크립트 파일을 대상으로 적용한 결과 최대 4배의 트래픽 감소와 50%의 소요시간 감소를 보였다.
