  • This study investigated the utilization of turmeric (Curcuma aromatica Salab.) for tofu manufacture and its effects on the quality characteristics and shelf-life. Various concentration (0.000%, 0.005%, 0.010%, and 0.015%) of turmeric were used to evaluate the shelf-life during tofu storage for 12 days at $10^{\circ}C$. The pH decreased with an increasing storage period, but the 0.010% and 0.015% tofu showed lower pH value than the 0.000% tofu, the acidity decreased with an increasing storage period. The water content of the turmeric tofu decreased with an increasing storage period. The turbidity gradually increased until 6 days of storage, and then rapidly increased at 12 days of storage. The microbial count of the 0.015% tofu was lowest during the storage period. In measuring the turmeric tofu color, the L- and a--values decreased during the storage period, while the b--value increased. In the texture analysis, hardness, gumminess, and brittleness of the turmeric tofu decreased 12 days of storage. Cohesiveness and springiness increased with an increasing storage period. In the sensory evaluation, Smoothness, after taste, and overall taste were highest for the 0.010% tofu. For the overall acceptability, the 0.010% tofu (with 0.45% mixed coagulant) attained the highest score.

  • 본 연구는 우리나라의 동남권 지역, 즉 부산, 대구, 울산, 경북 및 경남에 한정하여 16개 서비스업종을 5개 지식기반 및 11개 비지식기반 서비스업으로 분류하여 통계청 자료를 통해서 $1996{\sim}2004$년 기간 동안에 생산성 성과의 지역간 특성을 분석하였다. DEA 방법을 적용한 맘퀴스트 생산성 지수를 통한 추정 결과에 의하면, 첫째로 전 기간 동안 비지식기반 서비스업의 생산성 증가율이 지식기반 서비스업의 생산성 증가율보다 전체적으로 높은 것으로 나타났지만, 전반기($1996{\sim}2000$)에 2.1%p 격차에서 후반기($2001{\sim}2004$)에 0.6%p로 그 격차가 줄어들었다. 따라서 최근에 후자의 생산성 향상이 전자보다 높은 것으로 추정되었다. 둘째로 시 도별 생산성 성과를 비교해 보면, 대구의 경우에 5개 지식기반 서비스업종을 포함하여 7개 업종이 상대적 우위에 있는 것으로 나타났으며, 그 다음으로 울산과 부산 지역의 상대적 우위 업종이 많은 것으로 추정되었다. 하지만 경북은 2개 업종만 상대적 우위에 있을 뿐, 8개 업종에서 상대적 열위에 있는 것으로 나타나 다른 지역에 비해 상대적으로 열악한 것으로 나타났다.

  • Recently there is a growing interest in mobile cellular network providing multimedia service. However, the link bandwidth of mobile cellular network is not sufficient enough to provide satisfactory services to users. To overcome this problem, an adaptive framework has been proposed. In this study, we propose a new method of estimating DPR(Degradation Period Ratio) in an adaptive multimedia network where the bandwidth of ongoing call can be dynamically adjusted during its lifetime. DPR is a QoS(Quality of Service) parameter which represents the ratio of allocated bandwidth below a pre-defined target to the whole service time of a call. We improve estimation method of DPR using DTMC(Discrete Time Markov Chain) model by calculate mean degradation period, degradation probability more precisely than in existing studies. Under Threshold CAC(Call Admission Control) algorithm, we present analytically how to guarantee QoS to users and illustrate the method by numerical examples. The proposed method is expected to be used as one of CAC schemes in guaranteeing predefined QoS level of DPR.

  • 유 무선 네트워크의 기술의 발전과 단말기의 소형화 기술은 이동 환경에서 다양한 단말기를 이용하여 멀티미디어 콘텐츠를 이용할 수 있게 만들었다. 그러나 네트워크의 구성과 단말기들의 성능이 다양해짐에 따라, 동일한 품질의 컨텐츠를 다양한 이동 환경에 위치한 사용자에게 서비스를 제공하는 것은 매우 어려운 일이다. 그러므로 멀티미디어 스트리밍 시스템은 사용자의 네트워크와 단말기 환경을 고려하여 적응적으로 서비스를 제공하여 한다. 트랜스코딩 기법은 다양한 네트워크 환경에서 적응적인 비디오 스트리밍 서비스를 제공하기 위한 하나의 방법이다. 본 논문은 다양한 네트워크 환경에서 비디오 스트림을 서비스하기 위해 예측주기를 이용한 동적 프레임 삭제 트랜스코딩 기법을 제안한다. 제안된 트랜스코더에서는 부호기의 예측주기와 프레임율을 조절하는 삭제주기를 이용하여 트랜스코딩 과정에서 소요되는 시간을 최적화 할 수 있다. 실험 결과, 기존의 동적 프레임 삭제 트랜스코딩 기법에 비해서 본 논문에서 제안한 기법을 PSNR값은 유사한 반면에 계산 복잡도에서 매우 높은 성능 향상을 보였다.

  • Purpose: This study aimed to investigate the maternal health effects of internet-based education interventions on parturients during the postpartum period through a systematic review of randomized controlled trials. Methods: An electronic literature search of the Cochrane Library, CINAHL, EMBASE, Eric, PsycINFO, PubMed, RISS, and KISS databases was performed, using the combination of keywords such as 'parenthood education', '*natal education', '*birth intervention', 'internet-based intervention', 'randomized controlled trial'. The inclusion criteria were peer-reviewed papers in English regarding randomized controlled trials of internet-based postnatal education interventions. Educational interventions were delivered through any web, mobile, eHealth, mHealth, virtual reality, short message service, or social networking service platform. Quality appraisal was performed using the Risk of Bias 2 (RoB 2) for randomized controlled trials. Nine articles were yielded, and the intervention effects were analyzed. Results: Internet-based education interventions during the postpartum period affect maternal self-efficacy, postpartum depression, and successive breastfeeding; however, they do not affect maternal satisfaction and parenting confidence. Conclusion: This study demonstrated that internet-based education interventions affect maternal health status in terms of psychological, emotional, and physical wellness. Therefore, maternal health care professionals can utilize remote education using the internet or mobile-based interventions during the postpartum period.
