  • The contemporary age is a period of PR for the self. Regardless of how good the quality of goods or services offered is, if it is not made known to the buyers, a sell is impossible. As a result, the contemporary man is flooded with advertisements and is living in a time of over-saturated information. This is not much different in the medical services sector, as it too is experiencing an overflow of information due to the expansion of advertisement approaches to include not only the previous positive-method, but also the negative-method. In tandem, recent advancements in electronics and information technology has made possible a rapid increase in then number of internet advertisements. However, outmoded medical law, which was created to regulate newspapers and billboards, is still being applied to regulate today's modem medical advertisements. At the same time, collateral ordinances such as "corrective statutes for signs and advertisements" are not sufficient in providing the necessary regulatory countermeasures. In the midst of all this, as IPTV is scheduled to be broadcast nationwide starting next year, and with the market for search advertisements and internet advertisements annually growing at a rapid pace, it has become evermore urgent to come up with an adequate regulatory measure. Consequently, it is necessary to look into the possibility of restricting the medium and content of internet medical advertisements as well as realistic schemes for its realization. In particular, regulatory measures that take into consideration the special characteristics of internet advertisements should be found, and the necessity of an prior deliberation procedure and the likelihood of introducing a certification system should be examined.

  • Purpose: The aim of this study was to investigate the influence of nurses' awareness of healthcare accreditation on their job stress and turnover intention. Methods: Across-sectional correlation study design was used. Participants consisted of 143 nurses from two tertiary hospitals in Seoul and Gyunggido, South Korea. Data were collected in October 2016 using self-report questionnaires and analyzed using descriptive statistics, t-test, an ANOVA, Pearson's correlation coefficient, and multiple regression in SPSS/WIN 21.0. Results: Awareness of health care accreditation correlated negatively with job stress (r=-.63, p<.001) and turn over intention (r=-.50, p<.001). Awareness of health care accreditation was the factor that most influenced job stress, explaining 38% of the variance (F=23.10, p<.001). Awareness of health care accreditation and duty pattern were the factors that most influenced intention to leave, explaining 32% of the variance (F=10.35, p<.001). Conclusion: These findings suggest raising nurses' awareness of certification systems to reduce their job stress and turnover intentions. It will be necessary to provide support for the aggressive work nurses do and improve their work structure, highlighting the need for both manpower and institutional support. Accordingly, providing regular education programs and appropriate compensation schemes, by raising nurses' awareness of medical institutions' certification systems, is necessary.

  • 에드혹 네트웍은 동적으로 노드들을 조직화하고 네트워크 토폴로지를 사람들과 장치들 사이에 통신 인프라 없이 네트워킹이 가능하도록 하는 무선 모바일 시스템이다. 애드혹 네트워크 시스템이 매력적인 솔루션이지만 상업적으로 성장하는 것을 방해하는 결점들이 존재하며 이 결점들의 주된 문제는 보안에 관련된 것이다. 애드혹 네트워크 시스템은 평상 보안 공격에 취약하다고 알려져 있는데 이는 집중화된 키 분배센터와 노드들이 암호화 키와 디지털 증명서를 제공하기 위한 신뢰된 인증권한을 확립하기 어렵기 때문이다. 애드혹 라우팅 프로토콜 상에서 공격을 예방하기 위해 많은 알고리즘들이 사용되고 있으며, 본 논문에서 우리는 무선 멀티-홉 네트워크상에서 데이터를 안전하게 전송하는 시큐어 프레임워크에 대해 기술했고 기존의 존재하는 소스 라우팅 스키마와 제안된 스키마를 시뮬레이션 결과로 비교했다.

  • The purpose of this study was to learn the lifestyles of college students based on the green building certification system. The importance for environmentally friendly housing patterns will be changed and predicted to provide the basis for future residential development. The subjects of this research were 706 college students living in Jeonbuk province. The results of this research were as follows. College students' lifestyles were measured by self-confidence, family orientation, leisure orientation, economic orientation, and a digital directivity by factor analysis. In eco-friendly residential ratings, as the results of analysis according to the land use, the transportation, the energy resources, the environment load, the ecosystems, the interior environment, and the soundproofing of the interior environment came out to be higher than other factors. While coming out to be higher in the lower group in a digital directivity, the life style of the college students mostly came to be higher in the average of importance for environment-friendly housing. This result means that the college students want environment-friendly housing while attaching importance to the convenience of daily life, especially a digital directivity of housing. Thus, when we plan residences in the future, we will have to reflect the environment-friendly housing on the basis of the results of this research, and improve the environment which is contributing to help form college students' characters well.

  • Mobile Ad Hoc Networks (MANETs)은 기존의 기반구조에 의존하지 않고 자치적으로 구성${\cdot}$운영되는 네트워크이다. 다른 네트워크 토폴로지에서처럼, 보완은 MANET의 사용 확산에 중요한 요소이며, 특히 노드들의 구성이 자주 빠르게 변하고, 기존의 기반구조에 대한 접속이 불가능한 MANET에서 이러한 특성을 지원하는 보안 프로토콜의 개발이 중요하다. 유선의 기반구조를 적용한 네트워크에서 이미 개발되어 사용 중인 신뢰 모델과 인증 프로토콜은 MANET에서 사용될 수 없다. 이 논문에서는 아주 넓은 지역에 걸쳐 분포된 이동 사용자에게 효율적인 인증 문제를 주제로 주목하고, 위와 같은 MANET 환경에 맞는 새로운 인증 방법을 제안한다. 제안된 방법은 노드들에게 CA(Certification Authority)의 기능을 분산시키고 CA이 기능이 구현된 노드들 사이에 인증 정보를 효율적으로 공유하기 위해 randomized group을 사용한다. 또한 randomized group을 적용한 인증 메커니즘의 성능을 평가한다.
