가철성 보철물에서는 교합을 어떻게 형성하느냐에 따라 의치에 가해지는 힘의 크기가 결정되고 그에 따라 의치의 안정에도 영향을 미친다. 즉, 의치에 가해지는 외력이 의치의 유지력보다 크면 의치가 불안정해지지만 가해지는 이탈력을 줄여서 의치의 유지력보다 작아지도록 하면 의치의 안정을 얻을 수 있다. 그러므로 주의 깊은 검사와 진단과정을 통해 환자에게 적절한 교합을 설계하는 것은 의치 성공의 중요한 기준인 안정에 필수적이다.

In this paper, we surveyed state-of-the-art health and wellness platforms. The motivation of this paper is to review the state-of-the-art health and wellness platforms and their maturity with respect to adoption of latest enabling technologies. The is review is classified into four categories: healthcare systems, AI-assisted healthcare, wellness platforms, and open source health and wellness initiatives. From this comprehensive review, it can be stated that the contemporary healthcare systems are well-adopting wellness due to the concentration shift towards prevention. Thus, the gap between health and wellness is slowly yet carefully entering gray area. Where both the domains can freely invoke each other's services, and supporting enabling technologies. Furthermore, the biomedical researchers and physicians are no longer carrying the myopic views of trusting their knowledge for diagnosis. AI-assisted technologies based on machine learning and big data are influencing today's prognosis with trust and confidence.

Health information technology (HIT) is one of the most familiar tools to healthcare providers. It is used in routine practice to reduce cost, to improve clinical performance, and to improve patient safety. Patient safety is the driving force of recent expansion of HIT industry. But there are many evidences that it can be harmful to patient safety. Role of HIT and HIT-related error became big issues because more and more healthcare providers and healthcare organizations are willing to adopt it. Adoption rate of HIT in Korea is higher than that of United States. But researches of HIT regarding patient safety are rare. In this article, types of HIT, their mechanisms of improving patient safety and HIT-related errors were reviewed. Status of HIT in terms of patient safety in Korea was also reviewed. Knowledge of how HIT can improve patient safety, its' limitation, and how to make it safer is crucial to whom have to use it to improve patient safety. Impact of HIT on patient safety must be evaluated actively in Korea. HIT which was proven to improve patient safety must be widely adopted. Government must prepare a strategic plan to improve HIT quality, support hospitals financially and institutionally to introduce qualified HIT, and develop HIT infrastructures and standard designed for patient safety.

Conventional treatment techniques cannot meet the stringent modern water quality regulations emanating from the need to provide high quality drinking water. Therefore, a number of studies have suggested low pressure membrane filtration as a worthwhile alternative. However, a major constraint to the extensive use of this technology in low and middle income countries is the high operating and maintenance costs caused by the inherent predisposition to membrane fouling. Notwithstanding, pretreatment of feed water using techniques such as coagulation, adsorption, oxidation and bio-filtration is believed to control fouling. In this review paper, the existing scientific knowledge on membrane fouling and pretreatment techniques for controlling fouling in low pressure membranes is analyzed with the aim of providing new and valuable insights into such techniques, as well as unveiling crucial issues noteworthy for further studies. Among the techniques reviewed, coagulation was observed to be the most cost-effective and will remain the most dominant in the coming years. Although oxidants and magnetic ion exchange resins can also control fouling, the propensity of oxidants to form health treating precursors and the high economic implications of magnetic ion exchange resins will hinder their adoption in developing countries.

소프트웨어 기술의 생명주기가 점점 짧아지고 복잡해짐에 따라 그 기술을 이해하기가 힘들어 진다. 객체지향 기술채택을 더욱 잘 이해하는 것이 이 논문의 연구동기이다. 객체지향 기술이 전통적인 소프트웨어 프로세스 기술에 대한 새로운 패러다임이기 때문에 프로세스 중심의 구조지향 기술과 같은 기존의 소프트웨어 엔지니어링의 경험에 영향을 받을 수 있다. 본 연구의 목적은 이전의 구조지향 기술의 경험과 기술변화에 대한 개인적인 인식이 미국 기업체에서 객체지향 기술채택에 어떻게 영향을 미치는지를 실제로 조사하는데 있다. 2 X 2 유사 실험계획법이 사용되었다. 구조지향 방법을 사용한 경험과 새로운 기술에 대한 개인적 혁신정도(Personal Innovativeness)가 독립변수로, 객체지향 방법에 대한 사용편이성(Ease of Use)과 유용성(Usefulness)이 종속변수로 선정되었다. 데이터는 구조지향 방법과 객체지향 방법을 모두 사용한 경험이 있는 자료처리 및 관리협회(DPMA: Data Processing and Management Association)에 소속된 정보 시스템 전문가로부터 수집되었다. 연구결과는 구조지향 방법을 사용한 경험은 객체지향 방법의 사용편이성과 유용성에 영향을 주지만 개인적 혁신성은 영향을 주지 않는 것으로 나타났다. 과거의 구조지향 방법을 많이 사용하면 할수록 객체지향 방법의 사용편이성 값이 낮게 나타나기 때문에 이전 문헌에서 제시된 구조지향 방법의 객체지향 방법에 대한 지식간섭(Knowledge Interference) 현상이 있음을 실증적으로 보여주었다 마지막에는 본 연구의 한계점과 향후 연구에서 지식간섭을 줄일 수 있는 방안을 제시하였다.

Currently, there is widespread adoption of silicon-based technologies for the implementation of radio frequency (RF) integrated passive devices (IPDs) because of their low-cost, small footprint and high performance. Also, the need for high speed data transmission and reception coupled with the ever increasing demand for mobility in consumer devices has generated a great interest in low cost devices with smaller form-factors. The UWB BPF makes use of lumped IPD technology on a silicon substrate CSMP (Chip Scale Module Package). In this paper, this filter shows 2.0 dB insertion loss and 15 dB return loss from 7.0 GHz to 9.0 GHz. To the best of our knowledge, the UWB band-pass-filter developed in this paper has the smallest size ($1.4\;mm{\times}1.2\;mm{\times}0.40\;mm$) while achieving equivalent electrical performance.

This study found the digital divide of Korean elderly persons on the basis of the 2013-2017 survey data of the perception of media information adopters. The studied media were traditional ones, such as newspaper and TV. The media dependence of those in their 20s to 60s was compared and analyzed. As a result, regarding their dependence on newspaper, elderly persons in their 60s had 20.7% on average, 13.6% higher than the percentage (7.1%) of young persons. Regarding their dependence on TV, those in their 60s had 97.6% and those in their 20s had 63.7%, so that there was a wide gap of 33.9% on average. The smartphone penetration rate of those in their 60s was 61.3%(2015-2017) on average, which tended to rise. The elderly's dependence on traditional media featured Digital Divide which is found in the informatization process. Accordingly, in order to solve their digital divide, it is required to expand education in line with their knowledge level through remote online centers, develop inclusive ICT for convenience, and change philosophical policy paradigm in the dimension of quality of life.

Information and Communication Technology is now widely accepted by developing countries as a development tool in their efforts to alleviate poverty, enhance human development, and achieve Millennium Development Goals. Recognizing this untapped potential and development strategies incorporating ICT are being increasingly promoted and launched across the developing countries requiring a comprehensive ICT policy that plays a crucial rule, in particular, in the area of agriculture and rural development. While the potential advantages of ICT for development are enormous in developed countries, national policies of developing countries are yet to adequately reflect truly comprehensive and integrated strategies for harnessing and exploiting this potential. This paper tries to provide implication of ICT policy to the agriculture and rural development in developing countries, in particular through lessons learned from European Union (EU) IT policy. Through the examination of vital projects in the agriculture and rural development sectors and case study analysis of applied policies and strategies implemented in the European Union, this paper provides tangible examples and lessons for policy-makers and practitioners involved in the field. Hence, this study provides policy-makers the necessary tools, information and knowledge to facilitate the formulation and adoption of ICT policies and strategies in the agriculture and rural development sector.

Graphic health warning on the tobacco product package is a cost-effective tobacco control policy to convey information on harmful effect of tobacco use to health, and it is known not only to motivate smokers to quit but also to deter adolescents from start smoking. In case of Korea, amendments to National Health Promotion Act requiring implementation of graphic health warning had been submitted 13 times, from 2002 to May 2015. In May 2015, the amendment had been approved by the National Assembly and it enters into force on December 23, 2016. This research analyzed the discussions from Health and Welfare Committee of the National Assembly during the implementation of the graphic health warning in order to study decision making process of legislators. Study found that there was a shift from a general opposition on implementing graphic health warning at first to a harsh conflict over relaxation of the regulation once discussing the implementation in earnest. Particularly, while the group supporting the implementation of the graphic health warning or opposing relaxation advocated the amendment with scientific and knowledge-based evidences including the World Health Organization Framework Convention on Tobacco Control, the group opposing the adoption of the amendment itself or suggesting relaxation tended to defend their position with empathy on smokers or tobacco industries.

This paper presents an exploratory research on the application of the Technology Acceptance Model(TAM) to the domain of object orientation to investigate the validity of TAM in the perspective of its causal relationships. In the Management Information Systems(MIS) area, TAM has been applied to computer usage behavior as a specific technology adoption model. This paper also suggests the factors that affect the technology acceptance of object orientation in U.S. organizations through a modified TAM. Two major research questions are addressed. First, this research investigates the effect of these external variables on the dependent variable, the actual usage of object orientation in the viewpoint of knowledge interaction between structured methods and object orientation. Second, is TAM valid for the technology acceptance of object orientation in terms of its causal relationships? This study empirically explores the impact of the external variables on the level of actual usage of object orientation via the mediating variables in TAM. A structured questionnaire is administered to Data Processing Management Association(DPMA) professionals in US. The result of this study reveals one important contradictory finding that is not consistent with expectations based on related theory. TAM does not accommodate the technology acceptance of object orientation perhaps because object orientation is a complex and organization-level adoptive technology or the measures for the mediating constructs in TAM may not be appropriate in industry settings.
