Mobile devices equipped with various sensors have the potential of providing context-aware services. Location is one of the most common forms of context, which can be applied to diverse applications. In this paper, we present methods for learning and predicting users' routes between significant locations, e.g., home and workplaces, based on personal GPS data. A user's significant locations and routes between them are learned by a set of rules as well as clustering. When the user is moving, our methods can predict which of the learned routes is being taken now. After the route prediction, the user's next location can also be inferred. Our methods have been applied to the real GPS datasets from four subjects. For the next location prediction task, the achieved accuracy was 84.8%.

This paper describes a on-line monitoring and fault diagnosis system designed for the automation of a medium-size concrete plant. The system is based on the structure of a hardware system of data acquisition and a personal computer. Simulation results are presented to illustrate the system operation. It applies the preconstructed rules to the plant data for the diagnosis of weighing processes.

Purpose: This study was conducted to analyze the concept of nurses' emotional labor. Method: Rodgers's evolutionary concept analysis was used. Result: Nurses' emotional labor can be defined by two attributes: emotional distortion and self-regulation process. Antecedents of nurses' emotional labor include interactional, organizational and personal factors. The consequences of nurses' emotional labor are emotional dissonance and internalization of organizational display rules. Conclusion: Appropriate instrument to operationalize the concept need to be developed.

본 연구에서는 데이터 마이닝 기법을 활용하여 근로자의 이직준비 여부에 관한 예측모형을 구축하는 실험을 진행하였다. 이를 위해, 한국고용정보원 주관으로 수집된 "2015년 대졸자 직업 이동경로조사" 데이터를 사용하였다. 이직준비 여부 예측모형에는 의사결정나무, 베이즈넷, 인공신경망 알고리즘이 사용되었다. 전체 직종을 대상으로 한 분석에서는 의사결정나무 기반 예측모형에서 최고 예측률을 기록하였으며, 이직준비 여부에 영향을 주는 요인은 '근로시간 형태', '종사상 지위', '정규직 여부', '주당 정규 근로시간', '주당 정규 근로일', '개인의 발전가능성'으로 나타났다. 의사결정나무 기반 예측모형의 결과를 활용하여 근로자 전반에 관한 12개의 이직준비 여부 규칙을 최종 도출하였고, 도출된 규칙을 바탕으로 근로자의 고용유지 강화에 도움을 주는 방안들을 제안하였다. 또한 직종별 영향 요인을 분석하기 위해 직종을 사무, 문화예술, 건설, 정보기술 분야로 구분하여 실험을 진행하였다. 그 결과 사무 분야는 10개, 문화예술 분야는 9개, 건설 분야는 4개, 그리고 정보기술 분야는 6개의 이직준비 규칙이 도출되었고 이를 토대로 직종별 맞춤화된 고용유지 강화 방안을 제시하였다.

Internet-based distribution of digital contents provides great opportunities for producers, distributors and consumers, but it may seriously threaten users' privacy. The Digital Rights Management (DRM) systems which one of the major issues, concern the protection of the ownership/copyright of digital content. However, the most recent DRM systems do not support the protection of the user's personal information. This paper examines the lack of privacy in DRM systems. We describe a privacy policy and user's privacy preferences model that protect each user's personal information from privacy violation by DRM systems. We allow DRM privacy agent to automatically negotiate between the DRM system policy and user's privacy preferences to be disclosed on behalf of the user. We propose an effective negotiation algorithm for the DRM system. Privacy rules are created following the negotiation process to control access of the user's personal information in the DRM system. The proposed privacy negotiation algorithm can be adapted appropriately to the existing DRM systems to solve the privacy problem effectively.

지식 기반 사회가 구축되면서 처리해야 할 업무 프로세스의 규모가 커지고 분석할 정보의 양이 증가함으로 인해 프로세스 관리와 개선에 대한 필요성이 높아지고 있다. 본 논문에서는 비즈니스 프로세스 관리를 위해 프로세스 수행에 필요한 명확한 규칙과 정의를 관리하는 룰 에이전트를 적용하여 프로세스의 정확한 수행을 가능하게 하고 일정관리 에이전트를 적용하여 프로세스 수행에 투입된 개개인의 일정을 정확하게 측정하고 관리할 수 있도록 했다. 에이전트를 적용한 프로세스 관리 모델은 조직 차원에서 비즈니스 프로세스의 자동화와 프로세스 중복 제거를 통한 프로세스의 통제성, 유연성, 민첩성, 신뢰성, 재사용성을 높이고 개인 차원에서는 개인의 프로세스 역량을 측정하고 프로세스 개선점을 식별하여 개선할 수 있도록 설계 및 구현하였다.

개인건강기록 기술의 출현은 인터넷 서비스의 이용 뿐 아니라 패러다임을 변화시키고 개인 맞춤형 서비스의 중요성을 강조하고 있다. 하지만, 개인건강기록 기술이 헬스케어와 융합되면서 사용자 개인정보 침해와 사용자의 민감한 의료정보가 유출되고 되는 문제가 증가되고 있다. 본 논문은 개인건강기록 시스템에서 프라이버시 보호를 위한 보안 라벨링 기법을 제안한다. 제안 기법에서 개인건강기록 데이터는 환자의 요청이나 보안 라벨 규칙들에 의해 자동적으로 분류된다. 제안된 기법은 접근제어, 보호대책을 구체적으로 명시하고, 통신 보안 정책에 의해 요구되는 추가적인 제한을 결정하는데 사용될 수 있다.

To review the theoretical background of regulatory approaches to cross-border transfer of personal data, this paper divides major digital trade participating countries into four types according to the OECD - non-regulatory, post-intervention, pre-supervision, and national control. It then analyzes the US, Japan, the EU, and China respectively that belong to each type. South Korea, which is currently about to pass the amendment by the National Assembly, has identified that it is in the middle of post-intervention and pre-supervision, and needs to evolve into pre-supervision norms like the EU while it has to participate more actively in the process of establishing international digital trade rules. Korea first needs to sign digital trade agreements and promote mutual certification projects more actively from the standpoint of a medium-sized open country with growing digital companies and digitally-open consumers. Second, the government should fully consider the interests of not only companies but also various trade stakeholders including domestic consumers, when drafting and implementing trade policies. To this end, 'a single window approach' is needed not only at the Ministry of Trade, Industry, and Energy, but also at the level of the entire government which require an integrated form of digital trade policy governance.

본 논문에서는 소셜 네트워크 서비스 상에 공개된 개인정보의 소유자 식별 방법을 제안한다. 구체적으로는 트위터상에 언급된 지역 정보가 게시자의 거주지를 의미하는지를 자동으로 판단하는 방법이다. 개인정보 소유자 식별은 특정인의 개인정보가 온라인 상에 얼마나 노출되어 있는지 파악하여 그 위험도를 산정하기 위한 과정의 일부로서 필수적이다. 제안 방법은 트윗 문장의 어휘 및 구조적 특징 13개를 자질(feature set)로 활용한 소유자 식별 규칙들을 통해 지역정보가 게시자의 거주지를 의미하는지 판단한다. 실제 트위터 데이터를 이용한 실험에서 제안방법이 n-gram을 자질로 사용한 나이브베이지안 같은 전통적인 문서 분류 모델보다 더 높은 성능 (F1값 0.876)을 보였다.

The early postpartum period is crucial toward in recovery from childbirth and attainment of the maternal role. Maternal role attainment is a complex social and cognitive process of stimulus-response accomplished by learning. Helping for maternal role attainment is one of nursing goals in the early postpartum period. Based on King's conceptual framework for nursing, this study was planned as descriptive correlation study to determine the significant differences of the degree of nursery room nurses' role performance according to several variables of personal, interpersonal, and working system of nurses in nursery room. The purpose of this study was to contribute to the planning of nursing care to help maternal role attainment of the early postpartum period of mothers and to the development of relevant nursing theory. The data were collected from Feb. 3 to 28 by questionnaires with 273 nurses in nursery room. The instruments for this study were consisted of four parts : 21 questions for rot performance of nurse. 37 questions for personal system of nurse including 31 questions for role perception of nurse : 65 questions for interpersonal system including 63 questions for job stress of nurses , 18 questions for working system of nurse. The toos to measure role performance and role perception, and job stress of nurse were tested for internal reliability. Cronbach's Alphas were 0.9612, 0.9058, and 0.9649. The data were analysed by using in S.A.S. computerized program and included percentage, t-test, ANOVA Pearson Correlation Coefficient, and Duncan multiple range test. The conclusions obtained from this study are summerized as follows : 1. The mean score of the items of role performance was 2.12(SD=0.55) in Likert's 4 points scale. 2. The degree of role performance was significantly different according to role perception(p=0.0001), age (p=0.006), educational background(p=0.002) , and certificate of midwife (p=0.03) among variables of personal system of subjects. 3. The degree of role performance was significantly different according to job stress (p=0.0001) and numbers of children(p=0.006) among variables of interpersonal system of subjects. 4. The degree of role performance was significantly different according to having opportunities for baby(p=0.03), the degree of flexibility to bring baby to mother's room(p=0.046), the scope of visitor for baby(p=0.016) , the degree of flexibility of visiting for baby (p=0.049) , the degree of participation of nurse in establishing visiting rules(p=0.017), existence and/or nonexistance of rules for breast feeding(p=0.010) , existence and/or nonexistance of education for breast feeding (p=0.009), existence and/or nonexistance of breast feeding room(p=0.013) , concert methods for breast feeding (p=0.003), working place (p=0.0001), and career(p=0.019) among variables of personal system of subjects.
