As urbanization and its consequences become the issue of modern cities, the concept of Smart City comes as the solution. Though a lot of researches on the topic is done, still no clear definition is given for both: Smart City itself and the factors of a successful Smart City. While most of the literature centers the role of ICT it is not a sufficient condition for a city to become Smart; the role of intellectual capital is underestimated. Using a collection of Smart City definitions across the time and providing concrete cases, this research seeks to bridge definition gaps and creates a tool for understanding Smart Cities. Drawing on the findings of several case studies, this research derives several explanatory factors. The citizen's engagement and governance are identified as the two key success factors of Smart City Projects along with ICT and other factors as enablers. The research has purpose as follows: 1) To bridge definition gaps of the "Smart City" by defining the term "Smart City," based on existing concepts and characteristic mechanisms across times.; 2) To develop an analytical tool for Smart City success factors through Explanatory Variables.; and 3) To identify major challenges and barriers of Smart City Projects implementations and to provide recommendations and solutions, based on existing governmental initiatives and pilot projects. The research contributes to the knowledge of smart cities and ICT integration for urbanization issues solution. By applying the findings of this research at the managerial level stakeholders may benefit by getting higher efficiency of the Smart City Projects and by utilizing knowledge and values of a Smart City Projects in a prioritized way.

난독증은 초기에 발견해야 할 중요한 독서 장애요소이다. 비록 난독증 인구는 많지 않지만 국가적으로 관심을 갖고 지원해야 할 독서소외계층이다. 그러나 우리나라에서는 이것에 대한 인식과 관심이 매우 부족하다. 본 연구는 난독증이 본격적으로 드러나는 시기에 가장 민감하게 이를 선별해야 하는 학부모, 초등학교교사, 유치원교사, 사서(사서교사)들을 대상으로, 이들이 난독증에 대해 얼마나 인식하고 있으며, 그 차이는 어떤지를 알아보기 위한 것이다. 이를 위하여 대도시와 중소도시, 농 산 어촌에 거주하고 있는 학부모, 초등학교교사, 유치원교사, 사서(사서교사) 총 632명을 대상으로 설문지 조사를 실시하였으며, SPSS 20.0 프로그램을 사용하여 분석하였다. 조사결과, 난독증에 대한 인식은 직업, 거주지, 성별에 따라 차이가 있으며, 난독증에 대한 인지의 유무와 난독인을 직접 만나본 경험의 여부에 따라 차이가 있음을 알 수 있었다.

재발 사건 자료란 연구대상이 같은 종류의 사건을 반복적으로 경험할 때 발생하는 자료이다. 이러한 재발 사건은 사회과학, 자연과학, 공학, 의약학 등 다양한 분야에서 나타날 수 있다. 재발 사건자료를 분석할 때 연구자의 관심에 따라 사건 발생시간이나 사건 발생간의 소요시간을 이용하여 분석할 수 있다. 이 논문에서는 사건 발생시점간의 소요시간을 이용하여 불완전한 관측을 가진 재발 사건자료를 분석하고자 한다. 이 자료의 특징은 일부 관측대상들이 일정기간 동안 연구에서 제외되는 관측틈을 갖는다는 것이다. 이 때 관측틈은 불완전한 형태로 나타나게 되는데 그 이유는 관측틈의 시작시점은 알고 있지만 종료시점은 알 수 없기 때문이다. 이러한 미지의 종료시점을 추정하기 위해서 구간 중도 절단 방법이 적용된다. 따라서 종료시점이 추정된 후 프레일티를 포함한 회귀모형을 적용하여 공변량이 사건 재발에 미치는 영향을 알아볼 수 있다. 또한 제안한 방법을 실제자료에 적용하여 관측틈을 고려한 경우와 고려하지 않은 경우를 비교하고자 한다.

본 논문에서는 수표 영상 내의 필기체 문장 금액을 개별 단어로 분리하기 위해 연결 성분 간의 공간적 간격을 효과적으로 측정하는 방법을 제안하였다. 기존의 간격 측정 방법들은 과대추정 또는 과소추정과 같은 문제를 내포하고 있어 무제약적 필기 스타일에 의한 문자의 왜곡과 필기 공간의 제약으로 인한 연결 성분 간 중첩 및 접촉, 그리고 단어 간 또는 문자 간 간격의 불규칙성이 심하게 나타나는 문장 금액에 적용하는데 많은 어려움을 가진다. 본 논문에서는 기존의 측정 방식들을 수정 보완하여 측정 과정에서의 오류를 줄임으로써 단어 분리 성능을 향상시키고자 하였다. 단어 분리 실험 결과로부터 수정된 각 거리 측정법이 대응되는 기존의 측정법에 비해 $2-3\%$ 정도 향상된 단어 분리 성능을 보임을 확인하였다.

The purpose of this study was to examine the impact of the DISC behavioral patterns of health care workers on their job satisfaction, organization Commitment and job stress in a bid to suggest an ideal behavioral pattern of Nurses and Dental hygienist. The subjects were 184 health care workers who worked in general hospitals and clinics in Busan and Ulsan for a year or more. The collected data were analyzed using ANOVA and linear regression. As a result of analyzing the relationship of their DISC behavioral patterns to job stress, organizational satisfaction and organizational commitment, there were significant differences in job stress according to their DISC behavioral patterns(p=0.015). In regard to relationship between their DISC behavioral patterns and the subfactors of job stress, there were significant gaps in role conflicts(p=.007), conflicts with subordinates(p=0.001) and conflicts over underpayment(p=0.015) according to their DISC behavioral patterns. As a result of investigating the influential factors of job stress, factors produced significant results(p<.001). The findings of the study illustrated that out of the DISC behavioral patterns, type I was most prevailing among the health care workers, which indicated that the weight of this type was highest among the behavioral styles. There were no significant gaps in job satisfaction and organizational commitment according to their DISC behavioral patterns.

This study attempted to uncover the characteristics of health information non-seekers among the United States foreign-born population and identify potential predictors of their non-seeking behavior. The trends of foreign-born health information nonseekers over the past twelve years were also examined. Statistical analysis was conducted with two sets of Health Information National Trends Survey (HINTS) data: HINTS 2 (2005) and HINTS 5 Cycle 1 (2017) datasets. It was found that foreign-born nonseekers differ from foreign-born seekers in terms of a variety of variables including education, income, English proficiency, the uses of Internet and social media, ownership of digital devices, ownership of health insurance, perceived health status, and level of trust in health information sources. Among them, education, Internet use, and trust in online health information were identified as predictors of the foreign-born population's non-seeking of health information. In addition, three variables - race/ethnicity, age, and place of accessing the Internet - which were significant factors in the 2005 dataset, were no longer significant in the 2017 dataset, implying the possible influence of smartphones that reduces Internet accessibility gaps among different racial/ethnic and age groups.

Recent studies have focused on self-management of hypertension using smart devices (cellular phones, tablets, watches). It has proven to be an effective tool for early detection and control of high Blood Pressure (BP) without affecting patients' daily routines. This systematic review surveys the existing self-monitoring systems, evaluate their effectiveness and compares the different approaches. We investigated the current systems in terms of various attributes, including methods used, sample size, type of investigation, inputs/ outputs, rate of success in controlling BP, group of users with higher response rate and beneficiaries, acceptability, and adherence to the system. We identified some limitations, shortcomings, and gaps in the research conducted recently studying the impact of mobile technology on managing hypertension. These shortcomings can generate future research opportunities and enable it to become more realistic and adaptive. We recommended including more observable factors and human behaviors that affect BP. Furthermore, we suggested that vital monitoring/logging and medication tuning are insufficient to improve hypertension control. There is also a need to observe and alter patient behavior and lifestyles.

A model is presented in this paper to provide understanding of the supply chain integration and supply chain information practices' impact on the manufacturing industries. The supply chain information practices play a crucial role in sharing information between the members of SC network. Thus, it is important to develop a comprehensive understanding of the differences and similarities among ISI and information management. It will allow firms to systematically evaluate and carefully choose the information strategy. The empirical findings of this research offer essential and interesting insights about what role SCI, supply chain information and Supply chain ISI play in determining Malaysia's financial performance. The theoretical gaps addressed in this study are of significant importance, since a little empirical evidence is available regarding system infrastructure and supply chain information management's effectiveness. This research provides further paths of exploring system infrastructure and information management, thereby defining the manufacturing industries' next step in SCM struggle i.e. modifying total integrated SC principle in other manufacturing firms. The Resource-based theory discovered organizational resources as an essential organizational success ingredient. Therefore, in order to recognize its potential value, internal resources, for instance, information system and management must be fully utilized.

This study aims to test Voluntary Disclosure, Quality of Financial Reporting and Information Asymmetry as Moderation Variables. The Voluntary Disclosure variable is calculated using the Index Disclosure. This research uses quantitative methods and uses partial least square with EViews data analysis. The research sample consisted of 225 manufacturing companies listed on the Indonesian stock exchange for the period 2016-2018. The results of the study state that voluntary disclosure has a positive and significant effect on the quality of financial reporting through asymmetric information. The relationship between voluntary disclosure and asymmetric information has a negative effect on the quality of financial reporting, states that the disclosure of voluntary reports to companies can prevent information asymmetry, as well as the relationship of voluntary disclosure to information asymmetry states that companies that make voluntary disclosure will increase the interest of investors and other stakeholders. The quality of financial reporting states that if there is information asymmetry, the quality of financial reporting will also decline. The low value of relevance will affect the level of large or small information gaps between management and investors. The quality of financial reporting with increased relevance means that asymmetric information will have a negative impact on financial reporting.

The information systems of the Korea Postal Service are developed not for integration based on strategic purposes but for improvement of low-level business processes within each functional unit. Hence. the as-is level of the information systems is very insufficient for information integrity, and also shows substantial gaps. when compared to recent advances in information envconment such as internet, electronic govemment and so on in this study we suggest the design of the integrated platform to achieve integrity of postal service and banking servive. After briefly addressing the issues on information systems of the Korea Postal Service. we provide the framework of the integrated platform and action plan. We believe when this framework is put into use. It can contribute to competitive performance by giving the integrity and consistency in implementing infomation systems of the Korea Postal Service.
