  • This study focused on the effects of Korean cosmetics selection attributes on Mongolian consumers' brand reliability and purchasing intentions. We are also to verify the relationship impacts between consumers brand reliability in advertising media and the purchase intention on the type of promotion. 255 questionnaires were collected for Mongolian consumers and analyzed using SPSS and AMOS. The analysis shows that product price, image and quality that they have a positive effect on brand reliability, while familiarity has not had a meaningful impact on brand reliability. Moreover, brand reliability has been shown to have a positive effect on purchasing intention. As a result of the adjustment effect test according to advertising media, the relationship impacts between product selection attributes and brand reliability were shown positive effect in part. Finally, the type of sales promotion were found to have a controlling effect between brand reliability and purchasing intention. These results show applicable implications for Korean cosmetics companies in terms of marketing and operations when entering Mongolia's cosmetics industry.

  • This paper investigates audience perception on news content through comparison analysis on Comprehensive Programming Channels, TV chosun, JTBC, Channel A, and Terrestrial Broadcasting 'KBS'. How sensationalism created by video news affect audiences' credibility on news and media. The results shows that Comprehensive programming channels are assessed more sensational than terrestrial broadcasters by audience. Additionally, Comprehensive programming channels are assessed to get a lower credibility than terrestrial broadcasters by audience in the analysis of news and media credibility, comprehensive programming channels and terrestrial broadcasters. As a result, comprehensive programming channels showed lower news credibility and media credibility compared to that of the terrestrial broadcasters. This means that comprehensive programming channels must do the best not only recovering credibility from audiences but also constructing position as national broadcasting media.

  • The purpose of study was to measure the interrater reliability of the caries diagnostic instrument, Diagnodent(KaVo, Germany), using a new laser fluorescence technique. Occlusal surfaces and smooth surfaces of one hundred extracted human premolars and molars were examined by four dentists. Pearson correlation coeffcients were 0703 to 0.870 for occlusal surfaces and 0.764 to 0.932 for smooth surfaces (P<0.01, all). Reliability coefficients which were calculated by intraclass correlation coefficients were 0.9450 for occlusal surfaces and 0.9605 for smooth surfaces. Therefore, the interrater reliability of caries diagnosis by Diagnodent is very high, and the rater training would be necessary more for occlusal surfaces than for smooth surfaces.

  • There are the fault tolerance technology and the fault avoidance technology to analyze and evaluate the performance of computer system. To improve the relibility of software The N-Version Programming (NVP) technology is known to be the most objective and quantitive. However, when discrete probability distribution is used as estimation model, the values of it's component reliability should be same. In this paper, to resolve this problem, we adapted the genetic algorithms to NVP technology and implement the optimized simulate. and the results were analyzed and estimated. Through this study, we could optimize the reliability of each component and estimate the optimum count in the system reliability.

  • The analysis of reliabilities of process facilities often uses models based on the Weibull distribution. The parameters in these models are functions of operating conditions, and determined by experiments. Using these values, we calculate the reliability, mean time to failure, and standard deviation. The conventional method assumes that the operating condition is constant, and thus treats the model parameters as constants. In this paper, a reliability function is proposed which is applicable when the scale parameter is a function of time, and an analysis method based on this is also presented. A case study on a cooling fan resulted in a big difference from the conventional method to which the average operating conditions were applied. The proposed method is also applicable to other process facilities, and expected to effectively take into account the effects of changes in the operating conditions on the reliabilities of the facilities.

  • 본 논문에서는 품사 태깅 시스템에서 신뢰도 측정 방법에 대해서 기술한다. 품사 태깅 시스템의 신뢰도는 품사 태깅 결과에 오류가 포함되지 않을 확률이다. 일반적으로 신뢰도 측정은 오류확률에 기반한다. 정확한 오류확률을 추정하기 위해서는 일반적으로 품사 태깅 시스템에서 사용되는 말뭉치보다 훨씬 더 많은 양의 말뭉치가 필요하다. 이 문제를 다소 완화시키기 위해서, 본 논문에서는 좀더 정확한 오류확률 추정하기 위해 교차확인 방법을 이용한다. 본 논문에서 사용된 품사 태깅 시스템은 시험말뭉치에 대해서 61%의 신뢰도를 보였다. 이는 한국어 문장의 형태소 수가 평균 20개이고, 품사 태깅 시스템의 정확률이 97.5%일 때의 신뢰도에 해당한다. 본 논문에서 사용된 품사 태깅 시스템이 미등록어가 없을 경우에 97.68%의 정확률을 보이므로 제안된 신뢰도 측정 방법이 어느 정도 타당함을 알 수 있었다. 제안된 신뢰도 측정 방법은 구문분석, 정보검색 등 여러 분야에 응용이 가능할 것이며, 본 논문에서는 품사태깅의 오류검출에 적용해보았다.

  • In this paper, age exploration of ${\bigcirc}{\bigcirc}$ anti-ship missiles which were deployed on RoKN ships were analysed using parametric estimation method. Additionally, Life distribution and failure pattern of ${\bigcirc}{\bigcirc}$ anti-ship missile were analysed by using field data such as collected inspection, fail, maintenance record for 6 years. Storage failure and MTBF of missile and components were analysed by using reliability analysis s/w Weibull++ v7. The results were compared with maintenance policy including periodic inspection and MTBF which were analysed during development phase. Finally, the suggested methodology using field data analysis of oo anti-ship missile will be applied on re-estabilishment of maintenance policy of ${\bigcirc}{\bigcirc}$ anti-ship missile for TLCSM(Total Life Cost System Management) effectively.

  • 임상실험이나 신뢰성공학 분야에서 임의 중단자료를 이용한 비모수적 신뢰도 추정량으로 Kaplan-Meier 추정량과 Nelson형 추정량이 많이 사용되고 있다. 그러나 Nelson형 추정량은 평균제곱오차의 관점에서 Kaplan-Meier 추정량보다 추정능력이 우수한 반면 편의는 신뢰도가 감소함에 따라 양의 방향으로 점증하는 소표본 특성을 갖는다. Nelson형 추정량의 이러한 특성 때문에 신뢰도의 함수로 표현되는 잔여수명 분위수함수 등의 추정시에는 평균제곱오차의 관점에서 Kaplan-Meier 추정량보다 추정능력이 떨어짐을 볼 수 있다. 이러한 점을 고려하여 이 두 추정량을 가중평균으로 통합한 새로운 비모수적 신뢰도 추정량을 제안하고 추정량의 특성을 비교 분석하였다.

  • 본 논문은 원자력 발전소 안전계통/기기의 신뢰도를 평가하는데 있어서 필요한 데이터들을 관리하는 프로그램인 RAM-PRO의 계발에 관하여 기술하였다. RAM-PRO는 크게 두 가지의 프로그램으로 구성하였는데, 먼저 발전과장일지를 전산화하여 안전계통/기기와 관련된 시험, 운전이력을 데이터베이스에 저장하는 프로그램인 RAM-NOTE와 그 데이터로부터 신뢰도를 자동으로 계산하여주는 신뢰도 감시 프로그램인 RAM-REL으로 구현하였다. 이의 구현으로 인하여 실제로 월성 원자력 발전소 1호기의 예비/비상디젤발전기의 실제 데이터를 RAM-NOTE를 이용하여 입력하여 보았으며, 그 입력된 데이터베이스로부터 RAM-REL을 이용하여 신뢰도를 계산하여 보았다. 현재는 원자력 발전소의 모든 안전계통/기기에 적용 할 수 있도록 확장중에 있다.
