본 연구의 목적은 SST(Self-Service Technology)기반 서비스 이용자 관련 연구를 개관하고 귀인이론을 통해 이용자에 의해 발생되는 서비스실패와 이에 대한 회복전략을 이해하는데 있다. 연구목적을 달성하기 위해 사적영역에서 논의되고 있는 SST기반 서비스의 특성 및 이용자연구를 문헌조사를 통해 살펴본 결과 도서관 SST기반 서비스도 일반적인 SST기반 서비스와 크게 다르지 않음을 발견하였다. 일반적인 서비스와 다른 특성을 지니는 SST기반 서비스의 경우 이용자에 의한 서비스 실패가 발생했을 경우 적합한 회복 전략은 무엇인지를 귀인이론을 기초로 하여 제시하였다. 연구결과 도서관 SST기반 서비스를 비롯한 SST기반 서비스의 이용자에 의한 실패를 회복하기위한 전략은 서비스자체의 기술적 품질을 향상시키는 것이 중요한 것으로 나타났다.

The purpose of this study was to make a general overview of SST-Based(Self-Service Technology Based) services and understand SST-Based service failure by users and service recovery strategy based on attribution theory. To achieve these purposes, the study reviewed literature related to the unique characteristics of SST-Based service and user studies of SST-Based service. As a result, it was found that there are no significant differences between general SST-Based service and library SST-Based service. In addition, this study suggested appropriate service recovery strategies of service failure by users through the understanding of attribution theory. The finding was that the most important SST-Based service recovery strategy is to improve technical service quality of the services.

영국의 교육복지서비스는 아동복지에 초점을 두는 가족지원 사회복지서비스로서 교육복지, 아동보호, 고용, 교육복지실현을 위한 법적 지원, 퇴학아동지원, 방과후 교육, Home Schooling 지원, 특수교육필요여부 사정, 학교부적응 아동 과외활동지원, 학교부적응 아동을 위한 학부모 conference, 아동·가족·교사 상담, 교사 대상 교육 등 아동 전반에 걸친 복지실천을 위해 가족, 학교, 사법당국, 지방교육청/지자제, 그리고 관련사회복지서비스를 통합하고 매개(Integration & Networking)하는 역할을 한다. 영국의 교육복지서비스가 사회복지실천기술을 바탕으로 교육현장에 성공적으로 정착해 왔지만, 모든 서비스 과정에서 아동의 권리를 우선하는 노력과 교육현장의 욕구에 충분히 부응할 수 있는 전문교육과 연장교육의 실시, 그리고 기관들 간 통합조력, 그리고 지역자원의 확보와 연계 노력 및 업무 중복을 피하고 서비스의 한계를 정하는 역할조정은 보다 나은 서비스를 위해 지속적으로 요구된다. 이상과 같은 영국의 교육복지에 대한 비판적 탐구는 우리나라의 아동복지계가 통합서비스 실천 기반구축을 위한 노력과 진보된 전달체계의 개발을 지속할 때 결국 아동복지실천의 효과·효율성을 높이고 사회복지 실천의 전문역량을 극대화할 수 있다는 사실을 시사한다.

A review of the literature about ‘child’s maladjustment at school’reveals three principal perspectives which construe ‘the problems of child her/himself’ i.e. individual pathology, poor service of school to identify and meet the needs of a child, and a failure of family & parenting support for children experiencing difficulties in their lives. Facing these problems, the Education Welfare Service tries to identify the needs of a child at an early stage, take a lead role in child protection issues and family support for social work services required by school and statutory duties, doing the preventive role of the service. The Education Welfare Service in UK is family support service, focusing on the child welfare which includes education welfare, child protection, legal support for education welfare practice, withdrawn child support, after school education, home schooling support, assessment for special education needs, extracurricular activities for school maladjustment child, parental conference for school maladjustment child, coordination of school-legal system-local education office/local government office, and education related social work services. Although education welfare service in UK has been successful in education fields, which is based on social work practice and skills, there have been more needs in terms of child priority efforts in service processes, advanced and continuing education to adapt to changing societies, integration & coordination between organizations, finding resources in local society, avoiding duplication of efforts, and limiting of education welfare service. The critical explorations of education welfare service in UK as shown above indicate that child welfare service should make efforts to develop an advanced service delivery system for the integrated social work service. Those efforts will lead to the maximized effectiveness and efficiency of child welfare service for advanced social work practice.

코로나19 이후 비대면 심리치료가 대두되면서 국내외 전자 정신건강 서비스(e-mental health service : eMHS)가 활발히 중재되고 있다. 하지만 미술치료 분야는 eMHS라는 개념을 사용하지 않은 채 디지털 미술치료, 비대면 미술치료 등 다양한 용어로 서비스가 제공돼 왔다. 이에 본 연구는 eMHS로서 진행돼 왔던 디지털 미술치료에 대한 연구 동향을 살펴봄으로써 eMHS에 대한 개념과 역할에 대해 살펴보고자 한다. 본 연구는 2004년부터 2023년 3월까지 국내외에서 발행된 151편의 문헌을 수집하여 발행 연도에 따른 게재 논문의 수를 구한 뒤, 연구 진행 방법, 연구 진행 대상 및 특성, 연구 내용 및 주제에 관한 세부 내용을 분석하였다. 본 연구의 연구 방법에 따른 연구 결과는 다음과 같다. 첫째, 발행 연도에 따른 게재 논문의 수는 2021년(45편)이 압도적으로 많았다. 둘째, 연구 진행 방법의 경우 양적 분석(79편)이 가장 많았으며, 총회기 및 소요 시간은 미기재가 각각 44편, 42편으로 가장 많았다. 활용 기술과 매체 사용의 경우 화상(45편) 기술과 오프라인 매체(41편) 활용이 가장 많았다. 셋째, 연구 진행 대상 및 대상 특성의 경우 개인(54편)과 성인(63편)이 많았으며, 대상 특성에서는 일반이(63편) 압도적으로 많았다. 넷째, 연구 내용 및 주제의 경우 디지털(69편)과 치료 과정 및 성과 연구(51편)에 관한 내용이 가장 많았다. 이러한 연구 결과를 바탕으로 본 연구의 의의와 제한점에 대하여 논의하였다.

As non-face-to-face psychological treatment has emerged since COVID-19, electronic mental health services(e-mental health service : eMHS) have been actively implemented both domestically and internationally. However, art therapy services have been provided under various terms-such as digital and non-face-to-face art therapy, instead of eMHS. Accordingly, this study examined the concept and role of eMHS by investigating research trends on digital art therapy. The study collected 151 papers published from 2004 to March 2023 and analyzed research methods, subjects, characteristics, and the details of contents of the papers. Its results were as follows. Firstly, the number of papers was the highest in 2021 (45 papers). Secondly, in terms of methods, 79 papers were quantitative studies, 44 papers did not record the number of sessions, and 42 papers did not mention their hours. Concerning technology use, 45 papers used video, and 41 papers adopted offline media. Thirdly, individuals (54 papers) and adults (63 papers) were the majority of the research subjects, and general characteristics (63 papers) were the highest. Fourthly, the contents and topics were digital (69 papers) and the treatment process and its outcome (51 papers). Based on our results, the study discussed the significance and limitations.

최근 대학교육에 있어서 경험교육의 중요성이 날로 강조되고, 산학협력의 필요성이 증가하는 가운데 학습능력 향상과 인지·정의적 성장의 효과를 동시에 달성할 수 있는 전공연계 봉사-학습에 대한 관심이 확대되고 있다. 이에 본 연구는 응용실천학문으로서 현장경험교육의 요소를 중요시하고, 사회적책임감, 자기효능감 등 실천 가치를 강조하는 학문 분야인 사회복지전공 교과목에서 봉사-학습(Service-Learning)을 진행하고 현장연구(Action Research)를 수행함으로써 봉사-학습의 효과성을 확인하였다. 즉 선행연구 검토를 통하여 봉사-학습의 효과로 밝혀진 사회적책임감, 학습동기화, 직업준비도, 자기효능감에 있어서 실제로 효과가 있는지 분석한 것이다. 특히 본 연구에서는 봉사-학습 효과의 인과관계를 명확히 분석하기 위하여 통제집단을 둔 사전-사후검사설계로 분석하였으며, 학습에 대한 동기화와 직업준비도에 있어서 유의미한 효과가 있다는 분석결과를 얻었다. 이는 봉사-학습의 교육적 유용성을 보여준 결과라고 할 수 있으며, 봉사-학습 교수법은 향후 다양한 전공과정에서 전공별 특성에 맞게 적용해볼 만한 새로운 교수법이라고 볼 수 있다.

Korean universities' interest in experiential education and needs to collaborate with industrial organizations has grown recently. Along with this, interest in Service-Learning embedded in course work (Academic Service-Learning) has grown in the university setting because of its potential to enhance students' learning competency and cognitive and motivational aspects. This action research conducted during one social welfare course has investigated the effects of Service-Learning Experience on the following aspects(dimensions), such as social responsibility, career preparation, motivation, and self-efficacy. In order to investigate the effects of service learning experience on the above four aspects(social responsibility, preparation for careers, motivation, and self-efficacy), an experimental design was used. Students' semester-long experience of participating in the Service-Learning activities enhanced their motivation and career preparation. It is conjectured that the introduction of Service-Learning activities during the various courses are beneficial for students' learning.

본 연구는 조직 SNS 사용에 영향을 미치는 개인특성 및 환경특성 선행변인과 조직 SNS 사용의 결과변인을 알아보는데 목적이 있다. 그 동안 SNS 사용과 관련된 다양한 연구들이 있었으나, 조직 차원에서의 연구는 없었다. 또한 긍정적 측면에서의 사용효과만을 검증했으나, 본 연구에서는 부정적 측면의 사용 효과 역시 검증하였다. 연구를 위해 기존의 문항과 개방형 설문을 통해 만들어진 문항을 토대로 직장인 314명으로부터 자료를 수집해 분석하였으며, 그 결과 혁신문화, 학습조직, 관계지향성, 지적호기심으로 이루어진 선행변인이 모두 조직 SNS 사용과 유의미한 관계를 가지는 것으로 나타났다. 또한 조직커뮤니케이션, 팀응집력, 업무집중도, SNS 스트레스로 이루어진 결과변인 역시 조직 SNS 사용과 유의미한 관계를 가졌으며, 조직 SNS 사용이 많을수록 조직커뮤니케이션과 팀응집력은 높아지는 것으로 나타났으나 업무집중도는 떨어지고 SNS 스트레스는 높아지는 것으로 나타났다. 마지막으로 이러한 연구의 학문적 의의 및 실무적 시사점, 그리고 제한점과 추후 연구과제에 대하여 논의하였다.

Finally, the implications and limitations of this study, and the directions for future research were discussed.

Purpose: The purpose of this study was to investigate the relation between use of social network service and mental health(depression, anxiety and self-esteem), social health(personal relations and social support). Method: The subject of this study was 320 university students who are living in Daegu. The data was collected by using self reported questionnaire, and data was analyzed by using SPSS for windows ver 19.0. Result: First, there were significant differences in personal relation’s factors(confidence, sensitivity, openness) according to use of SNS. Second, usage of SNS correlated positively with anxiety and depression level, negatively with selfesteem and personal relation’s satisfaction and friendliness level. There were no relations between health and how many personal connection users have. Finally, according to research, factors in mental health correlated with factors in social health. Conclusion: Relation between mental, social health and usage of SNS identified in this study can have an impact on campaign of preventing addiction to SNS, warning excessive use of the SNS. This study can be utilized for future studies as the basis of education on proper SNS use.

Purpose: The purpose of this study was to develop a useful system to both patients and doctors that enabled the report of the blood pressure of hypertensive patients to the doctor using short message service (SMS). Method: The subjects of this study were 11 patients diagnosed of hypertension at C university hospital in Seoul. We measured the effects of the management system based on their blood pressure, compliance with medical instructions, subjective physical symptoms and patients’ satisfaction with the program after one month’s and two months’ application of the system. Result: The system was effective in lowering the systolic blood pressure, but not significantly effective for diastolic blood pressure, compliance to medical instructions or subjective physical symptoms. Patients’ satisfaction after participation in the program was 3~4 out of 5 points, suggested that the subjects were generally satisfied with the program. In addition, conformity to the program was as high as 81.7%. Conclusion: Based on the results above, we confirmed that the hypertensive patient management system was effective for managing blood pressure, and suggest subsequent research on the economic aspect of the system.

Purpose: The purpose of this study isto identify the mediating effects of interpersonal problems in the relationship between Social Network Service (SNS) use tendency and depression among university students. Methods: Data were collected from April 28 to May 7, 2018 and the participants included 222 university students, who responded to the question regarding SNS use tendency, interpersonal problems and depression. The data were analyzed by descriptive statistics, t-test, ANOVA, Pearson’s correlation coefficients, and multiple regression using the SPSS/WIN 23.0 program. Results: A positive correlation is found between depression and SNS use tendency (r=.24, p<.001), and among interpersonal problems (r=.62, p<.001), SNS use tendency and interpersonal problems (r=.34, p<.001). Interpersonal problems have a full mediating effect on the relationship between SNS use tendency and depression (Sobel test: 5.24, p<.001). Conclusion: These results suggest that it is important to manage interpersonal problems to prevent depression caused by SNS use tendency.

Purpose: The purpose of this study is to examine the mediating effect of sleep quality in the relationship between academic stress and social network service (SNS) addiction tendency among adolescents. Methods: The participants were composed of 204 high school students who were enrolled at private schools in Incheon metropolitan city. Data were collected from August 16 to September 10, 2019. The collected data were analyzed using a regression analysis, and SPSS Process Macro was used to test the mediating effect. Results: The direct effect of academic stress on SNS addiction tendency and the indirect effect of academic stress mediated with sleep quality about SNS addiction tendency were statistically significant. Conclusion: These findings suggest that positive intervention for academic stress and effective intervention program enhancing sleep quality should be provided for adolescents in order to prevent SNS addiction.

Thromboembolic events such as deep vein thrombosis(DVT) and pulmonary thromboembolism( PTE) are common among patients with cancer as a consequence of cancer- and treatmentrelated factors and have an effect on prognosis. Also, these events are the second most frequent cause of death in cancer patients. In 2008, Samsung Medical Center started the Anticoagulation service(ACS) which is a pharmacistmanaged anticoagulation service for cancer patients taking warfarin. The purpose of this study is to evaluate the effectiveness of ACS in patients with cancer. In this retrospective study, patients were first time warfarin users at Samsung Medical Center from March 31, 2010 to March 31, 2013. Each patient was followed up for 6 months after taking warfarin for at least 3 months. Patients were divided into two groups: ACS group(n=61) and non-ACS group (n=23). This study analyzed the baseline characteristics, warfarin indications, cancer types, contributing factors then compared anticoagulation control. The most common cancer type was lung cancer: 40.98%(n=25) of the ACS group and 65.22%(n=15) of the non-ACS group. The most common indications for warfarin in both groups were PTE or DVT. The ACS group spent significantly more time in the therapeutic range(TTR, 25.24±24.13% vs 47.43± 22.20%, p>0.001), as well as in the expanded therapeutic range(TTR within±0.2 units, 39.89±29.81% vs 65.40±22.67%, p=0.001). The percentage of time in the extreme range(INR <1.5 or >4.0) was 37.8 ±35.4% vs 20.5±19.5%(p=0.09). The interval of INR monitoring was 24.2±11.2 days vs 13.0±4.6 days (p<0.001). There was no major bleeding in both groups. The incidence of minor bleeding was 0.926/person-year in the ACS group and 0.815/person-year in the non-ACS group. These findings suggest that ACS group patients managed by pharmacists achieved significantly better INR control compared to non-ACS group patients as measured by the patients’INR values over time. These values remained in the therapeutic and expanded range. Based on the results of this study, collaborative practice using pharmacists and physicians may be an effective model for anticoagulation management for cancer patients.

본 연구는 정보서비스측면에서 국내 문헌정보학 교과목의 문제점을 다루어봄으로써 교육의 전문성과 현장적응성을 높이기 위한 방안을 제시하기 위한 것이다. 이를 위해 국내 32개 대학의 2005년과 2009년의 문헌정보학 교과목의 변화를 분석하였으며, 미국의 현황과 비교하였다. 조사결과, 국내 문헌정보학의 경우, 개론 및 원론위주의 교과목이 많은 부분을 차지하고 있는 것으로 나타났다. 또한, 대학 간 제공 교과목의 수에 차이가 많았으며, 도서관 현장에 대한 이해 및 관찰, 그리고 참여가 이루어지는 교과목이 부족한 것으로 조사되었다. 따라서, 효율적인 정보서비스 교과목의 운영을 위해서는 이용자와 주제에 대한 이해 및 서비스를 위한 과정의 제공과 도서관 현장과의 연계방안을 통한 실무교육을 강화할 필요가 있는 것으로 나타났다. 또한, 이용자교육과 커뮤니케이션 능력 향상을 위한 교과목의 확충과 대학별 특화도 시급한 것으로 분석되었다.

This study is to suggest the ways to make the education in Library and Information Science more professional and more practical by going through the problems in the curriculum of Library and Information Science in the aspect of ‘reference service'. For this purpose, the curriculum changes of 32 domestic universities offering Library and Information Science between 2005 and 2009 was analyzed and compared with the current situation of the U.S. The research has revealed some problems. First of all, it shows that the subjects such as the introduction of or the theory of library and information science still comprise a large portion of the domestic curriculum. Additionally, there seems to be much difference in the number of subjects between the universities. Lastly, there are few subjects which consist of the observation and understanding of the library field, and participation therein. Therefore, to operate the ‘reference service' curriculum effectively, it is necessary to offer courses for understanding the users and subjects and for the reference service. In addition, it is necessary to strengthen the practical education through a close connection with the library field. Finally, it is urgent not only to expand the subjects for improving the ability of user education and communication but also to make the curriculum of each university specialized.

Purpose: North Korean refugee women face multiple vulnerabilities during pregnancy and early childrearing due to fragmented support and limited familiarity with Korea’s health and welfare systems. Existing research has examined isolated barriers. This study used a service design approach to explore their maternal?infant care experiences and identify structural discontinuities across the care pathway. Methods: Data were collected from North Korean refugee mothers and service providers from April to August 2024. A service design approach using user journey mapping, thematic analysis, and service blueprinting was employed to examine user actions, emo- tional trajectories, frontline interactions, and backstage and interagency processes. Results: Five structural issues were identified: fragmented information, cross-institutional access barriers, cultural and emotional isolation, discontinuity in interagency linkage, and provider resource constraints. These issues accumulated along the pathway, increas- ing emotional burden, delaying timely care, and reinforcing avoidance behaviors. Mis- alignment between user needs and multi-agency processes was also evident. Conclusion: Maternal and infant care challenges among North Korean refugee women stem from structural fragmentation rather than individual factors. Based on these findings, the NK Mom Care Navigator?a pathway-based, culturally responsive service design model?is proposed to strengthen continuity of care and enhance equitable maternal infant support for vulnerable refugee families.

Popularly known to be originated in museums and art galleries, curation is widely applied in many other fields ranging from curation commerce to curated databases by today. Libraries also have started to provide different types of curation services such as data curation, digital curation, content curation, book curation, and social curation. However, the relationship between the curation service and the library service is not adequately studied and documented. The objective of this paper is to address that gap by analyzing the relationship between curation service and the library service. Particularly, this paper pays attention to study the relationship between curation service and library reference service. The research methods used by this study were an extensive literature review followed by some carefully selected real-world examples of curation services in libraries and other fields. The authors have analyzed and documented the origin and the meaning of two concepts, the challenges faced by library reference service, and the applicability of curation as a modest form of library reference service in the 21st-century. Based on the study findings, this paper concludes that curation service is not a new concept for the library but a natural evolution of the library reference service in response to the changing information environment and user expectations in the digital age.

본 연구는 교사양성교육과정 개선을 위해 새롭게 도입, 시행하는 ‘교육봉사’ 과목의 운영 전략으로서 Service-Learning을 도입, 이에 기반한 ‘교육봉사’과목의 운영 전략을 탐색하는데 목적이 있다. 이를 위해 예비교사 대상으로 이루어진 Service-Learning 운영 사례를 탐색하였으며, 현재 이루어지고 있는 교육봉사 과목의 운영방법과 현직 교사들의 교육봉사활동 요구를 파악하였다. 연구결과 대부분의 대학들이 학생들의 봉사시간만 확인하는 형태로 과목을 운영하고 있었고, 현직 교사들은 교수학습활동, 학생생활지도, 행정업무보조 등의 영역에서 봉사활동이 이루어지기 원하고 있었다. 교육봉사가 이루어지는 현장의 요구와 교육봉사 교과목의 설립취지를 고려하면 Service-Learning의 방식으로 운영되는 것이 바람직할 것이다. 즉, 관련 교직이론 및 전공 교과목과 교육봉사 과목이 연계 운영되며, 예비교사들이 자신의 봉사활동을 설계할 수 있어야 하며, 충분한 성찰이 이루어질 수 있도록 다양한 성찰질문을 제공하고 성찰내용을 공유하고 평가할 수 있는 기회가 제공되어야 한다. 이를 위해 대학은 지역사회와 파트너십을 형성하고 지역의 실제적 필요를 파악하는 등의 적극적인 노력을 기울여야 할 것이다.

The new course, 'educational service' have been included in the educational program for pre-service teacher in order to improve the program. The purpose of this study was to present strategies of design & implement on this course based on Service-Learning. The Service-learning combines service activities with students' learning in a way that improves both the students and the community. A literature review and a qualitative survey were performed to find out strategies. The results of this study can be summarized as follows; 1) Most of university managed their 'educational service' course by checking students' volunteering times. 2) In-service teachers want to be implemented in the following areas; teaching-learning, student guidance, and administration. Therefore, 'Educational service' course should be managed by considering the next strategies. First, 'Educational service' course should be connected with 'educational theory' course. Second, students should design their volunteering activities. Third, the course contains reflection guidance. Fourth, universities try to make partnership with their community and know it's volunteering needs.

최근 대학 수업에서 SNS(Social Network Service)를 활용하여 교수자와 학습자 간의 협력적인 상호작용 및 의사소통을 향상시키고자 지속적인 노력이 이루어지고 있다. 본 연구는 SNS를 활용한 수업에서 예비교사의 자아탄력성, 사회적 지지 수준이 수업성과 인식에 어떠한 관계가 있는가를 알아보기 위하여 대전·충남지역 대학의 예비교사 137명을 대상으로 하여 설문조사를 실시하였다. 연구 결과에 따르면, 여학생보다 남학생의 수업 만족도가 높은 것으로 나타났으며, 자아탄력성-사회적 지지, 자아탄력성-수업 만족도, 사회적 지지-수업 만족도, 사회적 지지-학기 만족도, 수업 만족도-학기 만족도 간에 유의한 상관이 있는 것으로 나타났다. 또한 자아탄력성과 사회적 지지가 수업성과 인식에 유의한 영향을 미치는 것으로 나타났다. 이에, 대학 교직과정에서 다양한 뉴미디어를 활용한 수업을 성공적으로 운영하기 위해서는 학습자 특성 및 수업활동 적응에 보다 세밀한 관심을 기울일 필요가 있다.

In recent university classes, consistent effort to improve co-operative interaction and communication between student and professor utilizing SNS(Social Network Service) is being made. This research conducted survey study with 137 pre-teachers in Daejeon & Chungnam area in order to find the relationship between pre-teachers’ ego resilience, level of social support and awareness of the instructional outcome in classes that incorporate SNS. According to the result, it has been found that male’s class satisfaction is higher than female’s class satisfaction, while significant correlations have been found between ego resilience-social support, social support-class satisfaction, social support-semester satisfaction, and class satisfaction-semester satisfaction. Also, ego resilience and social support have significant effect on awareness of the instructional outcome. From these results, a rather close attention towards students’ characteristics and their adaptation in class is needed in order to successfully carry out classes that incorporate various new media.

소셜로그인 서비스(authing service)는 온라인 플랫폼들간의 연결을 더욱 용이하게 함으로써 온라인 플랫폼 생태계에 긍정적인 영향을 미치고 있다. 소비자들은 추가적인 로그인 없이 다른 플랫폼으로의 접근이 가능해졌으며 플랫폼들은 다른 플랫폼들로부터 잠정적인 소비자들을 유치할 수 있다는 점이 이점으로 작용한다. 하지만 보다 쉽게 다른 플랫폼에 접속할 수 있는 소셜로그인 서비스는 플랫폼 생태계의 보안을 취약하게 만들고 있다. 즉, 플랫폼들 간의 연결이 많아질수록 소비자들의 편의성은 높아지는 반면에 플랫폼의 보안은 취약해진다. 그러므로 본 연구는 소셜로그인 서비스의 편의성과 보안의 상반관계를 고려하여 플랫폼이 결정해야 하는 적절한 수준의 소셜로그인 서비스를 제시하였을 뿐만 아니라 소셜로그인 전략이 전체적인 플랫폼 생태계에 미치는 영향에 있어서는 게임이론법을 적용하여 분석하였다. 본 연구를 통해 제시한 결과는 다음과 같다. 첫째, 소비자들의 해킹에 대한 기대손실이 낮은 경우, 플랫폼 생태계 전반의 구성원 수는 증가하게 된다. 둘째, 소셜로그인 서비스에서 소비자가 증가할 경우, 연결된 플랫폼들(joint sites)은 소비자들로부터 더 많은 이익을 창출할 수가 있다. 마지막으로, 소비자들의 해킹에 대한 기대손실이 낮은 경우, 플랫폼 제공자들은 플랫폼의 보안과 관련된 노력이 필요하다. 본 연구에서 소셜로그인 서비스를 제공하는 플랫폼 기업들에 대한 연결성과 보안에 대한 방법을 제시하였고, 이외에 전체플랫폼을 분석, 관리하는 정책담당자에게 정책적인 방향을 제시하였다.

Online platforms recently expanded their connectivity through an authing service. The growth of authing services enabled consumers to enjoy easy log in access without exerting extra effort. However, multiple points of access increases the security vulnerability of platform ecosystems. Despite the importance of balancing authing service and security, only a few studies examined platform connectivity. This study examines the optimal level of authing service of a platform and how authing strategies impact participants in a platform ecosystem. We used a game-theoretic approach to analyze security problems associated with authing services provided by online platforms for consumers and other linked platforms. The main findings are as follows: 1) the decreased expected loss of consumers will increase the number of players who participate in the platform; 2) linked platforms offer strong benefits from consumers involved in an authing service; 3) the main platform will increase its effort level, which includes security cost and checking of linked platform’s security if the expected loss of the consumers is low. Our study contributes to the literature on the relationship between technology convenience and security risk and provides guidelines on authing strategies to platform managers.

Windows 운영체제는 응용프로그램이 쉽고 편리하게 다양한 암호화 알고리즘을 사용할 수 있도록 CSPs(Cryptographic Service Providers)를 제공하고 있으며, 이 응용프로그램은 CryptoAPI (Cryptographic Application Program Interface)를 통하여 선택적으로 다양한 CSP 모듈을 이용할 수 있다. 이 때 CryptoAPI와 CSP 모듈 사이에서 함수로 전달되는 파라미터의 분석을 방지하기 위해 핸들을 이용한 안전한 데이터 접근 방식을 사용하고 있다. 본 논문에서는 새롭게 제시한 메모리 역추적 기법을 통해 위와 같은 보안기법에서도 개인키/비밀키와 같은 중요한 데이터가 노출되는 취약점이 존재한다는 것을 실험을 통해 증명하였다

In Windows operating system, CSPs(Cryptographic Service Providers) are provided for offering a easy and convenient way of using an cryptographic algorithms to applications. The applica-tions selectively communicate with various CSPs through a set of functions known as the Crypto API(Cryptographic Application Program Interface). During this process, a secure method, accessing data using a handle, is used in order to prevent analysis of the passing parameters to function CryptoAPI and CSPs. In this paper, our experiment which is using a novel memory traceback method proves that still there is a vulnerability of private key and secret key disclosure in spite of the secure method above-mentioned.

The advent of Network Function Virtualization (NFV) technology has brought flexible provisioning to Fog?Cloud Computing-based Networks (FCCNs) for enterprises to outsource their network functions to data center networks. Service Function Chaining (SFC) is a networking concept in NFV by which traffic is steered through an ordered set of Virtual Network Functions (VNFs) composing an end-to-end service. When hundreds of users outsource their network functions to FCCN, the optimal placement of VNFs in the network becomes important for assembling SFCs with the aim of resource utilization efficiency. Motivated by the scalability shortcomings of existing schemes, we propose Deep Reinforcement Learning (DRL)-based approaches by simultaneously considering parallelized SFC and reuse of VNFs to solve this problem, i.e., Asynchronous Advantage Actor?Critic (A3C). A parallelized SFC consists of several sub-SFCs, which can reduce delay and guarantee availability. Also, reuse of preliminary VNFs in SFC placement can improve computation acceleration. The proposed scheme pursues the maximization of the long-term cumulative reward for the trade-off between Quality of Service (QoS) and service cost. The results of the experiments show that the proposed scheme performs better than the state-of-the-art methods.
