The increase in the number of large cities and the size of their population sharpens attention to the new role of cities as entities to ensure a high-quality, safe and modern life of citizens, which has become significantly more active in recent years. The rapid spread of smart cities in the modern world has actualized the issue of analyzing their success and assessing the role of various factors in this. Every success of a smart city is always the result of a unique combination of the most modern technologies, environmental and social initiatives, skillful and consistent management, as well as available human potential. The purpose of the article is to analyze the success factors of smart cities based on the generalization of the results of the most famous ratings. In order to identify the impact of various factors, primarily intellectual, on the success and leadership positions of smart cities, the following ratings were consistently analyzed: Smart City Index (SCI), City in Motion Index (CIMI), Global Power City Index (GPCI), Global Cities Index (GCI), Global Cities Outlook (GCO). They have a different list of indicators and main pillars (dimensions), but all ratings take into account aspects such as: governance, ICT, mobility, functionality, human capital, etc. The highest correlation coefficient, that is, the strongest linear relationship of the CIMI index was found with such factors as: Human capital, Economy, Governance and Technologies. Summarizing the results of the TOP 20 smart cities according to different ratings allowed us to confirm that the list of leaders is very similar in all ratings. Among those cities that are in the TOP-20 in all five indexes are: London, Sydney and Singapore. There are four indices: New York, Paris, Tokyo, Copenhagen, Berlin, Amsterdam, Melbourne. Achieving leadership positions in smart city rankings is always the result of a combination and synergy of certain factors, and first of all, it is the quality of human capital. The intensity and success of the use of information and communication technologies in locality management processes, city planning and improvement of the city's living conditions depend on it.

Purpose: The purpose of this study is to examine the factors that influence the pre-use expectation and the continuous usage intention of the OTT services. Methods: For empirical analysis, the survey for this study was administered with many anonymous people who had previously used any of the OTT services and valid 192 data were analyzed by SPSS and PLS-SEM. Results: The results of this study are as follows. Personalization and understandability in the information quality didn't significantly affect confirmation. Ease of use and search of the system quality significantly affected confirmation. Also, it was found that content diversity, content recency, and content playfulness as the characteristics of the content quality significantly affected the expectation confirmation. OTT service fees also significantly affected the expectation confirmation. It also significantly affected perceived usefulness and satisfaction. Finally, satisfaction positively influenced the continuouse intention to use. Conclusion: The findings of this empirical analysis shows that the specific characteristics related to the relationship of expectation confirmation, perceived usefulness, satisfaction, and continuous usage intention with respect to OTT services through the Post Acceptance Model (PAM). Because system quality, content quality, and service fees meeted users' expectations, OTT services need a strategy that can boost the users' positive perceptions or experiences by reinforcing these three factors.

국내뿐 아니라 전 세계적으로 환경문제가 이슈화 되면서 저탄소 녹색성장이라는 수식어는 정치, 경제, 사회 등 전 영역에서 자주 사용되고 있다. 저탄소 녹색성장 정책으로 환경에 대한 관심이 증대되고 있으며, 정부는 환경보호와 환경관리를 위해 환경규제강화와 친환경정책을 함께 펴고 있다. 본 연구는 녹색기업과 환경규제위반기업간의 특성차이를 실증분석 하였다. 환경의식, 재무적 능력, 기업의 구조적 특성 및 기술적 특성 등 기업의 특성과 기업의 환경친화성과의 관계를 실증분석 하였다. 가설은 환경관리 담당자들과의 인터뷰와 기존연구를 바탕으로 설정하였으며 분석결과는 다음과 같다. 첫째, 녹색기업과 환경규제위반기업간의 특성관계에서 기존연구의 결과와 달리 환경의식의 대위변수인 지배주주지분율은 유의한 결과를 얻지 못하고 기각되었으나 ISO 14001 인증여부는 유의한 결과를 보이고 있어 환경성과에 영향을 주고 있음을 확인하였다. 둘째 기업의 재무적 능력은 녹색기업과 환경규제위반기업간의 특성에서 유의한 결과를 얻지 못하고 기각되었다. 이는 환경성과와 재무능력은 관련이 없다는 것으로 재무성과가 더 좋은 기업이거나 나쁜 기업일지라도 반드시 환경성과에 영향을 주는 것이 아니라는 것을 시사하고 있다. 셋째, 기업의 구조적 특성은 녹색기업과 환경규제위반기업간의 관계에서 기존연구와 다른 결과를 보여주고 있다. 자본집약도의 지표인 유형자산비중과 수출비중은 기각되었고 종업원비중은 유의한 결과를 얻었지만 기존연구와 반대의 결과로 종업원비중이 높은 기업이 환경규제를 위반한다는 결과를 보이고 있다. 넷째, 기술적인 능력이 환경성과에 영향을 준다는 유의한 결과를 얻었는데 그 결과는 기존연구와 같다는 것을 확인하였다. 즉 연구개발투자비중이 높을수록 환경규제를 준수한다는 것으로 확인되었는데, 이는 녹색기업이 환경규제위반기업보다 연구개발투자를 많이 하고 있으며 환경기술능력을 향상시켜 환경관리를 잘 하고 있음을 확인하였다.

Some of the steel works and machine tool manufacturers representing the whole spectrum of these industries in Korea are surveyed with a viewpoint from total quality control. The operation of quality control system in these fields has been found to be unsatisfactory partly because these industries are relatively young compared with those in advanced foreign countries, and partly because there have been insufficient financial and top management support. Some suggestions are made for the improvement of steel and machine tools quality. One of them is introducing the industrial engineering techniques, with additional quality control costs and full management support, into the company-wide quality control system.

As attention to the Internet from both companies and individuals is rapidly on the increase, hundreds of new websites are opening in a single day. Along with such a high attention to the Internet, to set up an effective website needs efficient evaluation and reliable evaluation criterions for the website. The existing homepage contests and evaluation models are limited to certain websites in a special field or to the systemic side and to the contents, which in fact weakened the development of detailed evaluation sections and items possibly measured. This study is designed to integrate and seek out methods and success factors that should be considered when a website is built up, discovering evaluation criterions and making evaluation models objectively possible to be measured. The study focused on investigation into a new measurement standard and model by considering the previous studies, in order to suggest the followings: Centering the 7 top evaluation sections by type of each website such as (1) Service, (2) Mechanism, (3) Structure & Navigation, (4) Usability, (5) Contents (6) Community, (7) Communication, the study suggests an objective and reasonable website evaluation model on a basis of common factors considered in an integral and optimum view.
