The aim of this retrospective study was to compare the amount of marginal bone loss between upper anterior area and upper posterior area with 71 upper single-tooth restorations on 2 stage machined $Br{{\aa}}nemark$ implants since Jan 1995. The second aim was to compare the bone defect group which had dehiscence and fenetration and the others in the upper anterior region. The results were as follows. 1. The most frequent reason of missing tooth in the upper anterior region was trauma by 61%. While upper posterior region showed various reasons such as congenital missing, advanced periodontitis, trauma. 2. Peri-implantitis with fistula occurred 1 of 41 implants in the upper anterior group in 1 year after loading and 2 of 32 implants in the upper posterior group failed before loading. The 1 year success rate of upper anterior group was 97.56 %, and 93.75 % for upper posterior group. 3. The mean marginal bone loss in the upper anterior group was 0.44${\pm}$0.25 mm, while 0.57${\pm}$0.32 mm in the upper posterior group. There was statistically significant difference in the amount of mean marginal bone loss (P<O.05). 4. The mean marginal bone loss of bone defect group was 0.40${\pm}$0.10 mm at one year, and 0.48${\pm}$0.26 mm for the control group. No statistically significant difference of mean marginal bone loss was showen between bone defect group and the others at implantation. According to the results, the upper anterior region showed less marginal bone loss than the upper posterior region. In case of missing single upper tooth, careful consideration on recipient residual ridge to determine proper implant diameter and length, sufficient healing time, proper loading would lead to implant success. Single tooth implants in the maxilla seemed to be an alternative to fixed partial dentures without damage to adjacent teeth.

When a cable-stayed bridge is under construction, the cable tension that changes according to the construction phase is the index indicating the proper construction management. In this study, the vibration method using the least square estimation has been implemented to monitor changing tensions of two multi-strand cables of a cable-stayed bridge under construction. The test bridge is Hwamyung Bridge in Korea with a prestressed concrete box girder. The field tests are executed during the second tensioning stage just after the installation of the key segment. The tensions of two cables are measured before and after the tensioning and 5 days later (i.e., after finishing the tensioning of all cables). The accuracy of the estimated tensions by the vibration method has been improved by employing proper effective lengths of the cables. The measured tensions are compared with the result of the lift off tests and design tensions. The vibration method shows very good performance in monitoring the changing tensions according to the construction phase with minimal error.

미디어 환경이 급변하면서 수용자들의 뉴스 이용 행태도 변하고 있다, 수용자들이 뉴스를 포털, SNS, 유튜브를 통해 접하는 비율이 높아지면서 신문은 구독률, 열독률 하락 등 그야말로 신문 위기의 시대를 맞고 있다. 여기에 최근 언론의 신뢰도마저 최하위를 기록하면서 신문기업도 새롭게 도래한 디지털 시대에 생존의 길을 모색하고 있다. 신문기업들의 디지털 퍼스트 전략은 초기 지면 신문의 내용을 인터넷으로 서비스하는 정도에서 이제는 뉴스 자체를 하나의 콘텐츠 개념으로 확장해 전개되고 있다. 이러한 가운데 주간 발행, 교계라는 특수 분야를 다루는 기독교 신문들 역시 급변하는 미디어 환경변화에 따른 디지털 전략이 필요한 상황이다. 이 연구에서는 기독교 신문인 교단지들이 신문 위기의 시대를 어떤 형식으로 맞고 있는지 살펴보고 변화하는 시대에 맞는 디지털 전략을 모색해보고자 한다. 이를 위해 교단의 신문을 발행하는 기독교 주요 6개 교단의 교단지 기자와 심층인터뷰를 실시했다. 연구결과, 교단지들 역시 신문 위기의 시기를 체감하고는 있었으나 일반 언론과는 다르게 구독률, 열독률, 신뢰도는 높은 것으로 인식됐다. 이는 교단지가 교단 소속 발행지이고 교회와 사회, 목회자와 성도를 잇는 중간매개의 역할을 하는 특수성에 따른 것으로 분석된다. 그러나 교단지 역시 변화하는 시대에 대응하기 위해서는 뉴미디어를 활용한 디지털 전략이 필수적인 것으로 인식하고 있었다. 이러한 필요성에도 불구하고 교계 안에는 인식의 부족과 제작 환경의 열악함, 전문인력 문제 등의 장애요소가 존재한다. 이에 이 연구에서는 뉴스 정보에서 확장된 콘텐츠 개념의 기획, 수용자들과의 소통방안, 신문지면과 영상채널 콘텐츠의 차별화 전략, 교단 내신학교, 기관과의 연합 등의 전략을 제안한다. As the media environment changes rapidly, the news usage behavior of the audiences is also changing. As the audiences expansively access news through portal sites, SNS, and YouTube, the newspapers are facing a crisis, such as a decrease in subscription or in readership. In addition, as the credibility of the newspaper recently recorded low, newspaper companies have been searching for new ways to survive in the digital age. Newspaper companies have established digital-first strategy to provide news services in the digital format, rather than simply providing the contents of newspapers through the Internet as they did so at the beginning stage. The rapidly changing media environment also requires new strategies for the special weekly publications and daily newspapers within the Christian world. To that extent, this study examines how Christian newspapers have responded to the era of crisis and searched for strategies suitable for the changing times. This study has conducted in-depth interviews with the journalists from the six major Christian denominations that publish their newspapers. As a result of the interviews, it was found that unlike the general media, the Christian newspapers have recorded high in the rates of audiences" subscription, readership, and credibility. It looks that Christian newspapers are different from the others in that they are publications of the denominations that mediate between the church and the society, and between the pastors and the believers. However, the journalists believe that the Church newspapers also need digital strategies to attentively respond to the changing times. Despite the necessity, it was also found that there are obstacles within the Christian world, such as a lack of awareness about digital technology, poor production environment, and a lack of professional manpower. Therefore, this study proposes new strategies including content planning based on a new concept of media content besides a simple digitalization of newspaper content, communication with audiences, differentiation strategies between paper version of news and video channel content, and alliances with seminaries and institutions within the denominations.

This study was a correlation study to analyze the effects of smartphone usage time on food choice perceptions and behavior in middle school students in Seoul areas. The subjects to be surveyed were middle school students attending junior high schools in Mapo-gu, Seoul. A total of 133, 102, and 102 students were in the first second, and third grades, respectively. The usage time of smartphones was the weekday and weekend usage time except for the call function. Food choice perception and its behavior as dietary habits were constructed referring to previous research and food balance wheels data for the correct dietary habits of the Ministry of Health & Welfare and Korean Nutrition Society. The food choice behavior was categorized into non-recommended food and recommended food. The results are summarized as follows. First, the longer the time spent on smartphones, the less favorable the perception of correct food choices. Second, the higher the dependence on smartphones, the less favorable the perception of correct food choices. Third, the correct perception of food choices has been shown to reduce food choices, known as non-recommended foods. In addition, proper perception of food choices has been shown to increase the choice of recommended foods. In conclusion, the usage time and reliance of smartphones of middle school students was found to affect the food choice behavior by lowering the perception of correct food choices. This research is expected to form the basis for the development of programs and educational materials that can be of assistance to adolescents who are experiencing difficulties.
