  • The hybrid architecture of content delivery networks (CDN) and peer-to-peer overlay networks (P2P) is a promising technology enables effective real-time streaming services. It complements the advantages of quality control and reliability in a CDN, and the scalability of a P2P system. With real-time streaming services, however, high connection setup and media delivery latency are becoming the critical issues in deploying the CDN-P2P system. These issues result from biased peer selection without location awareness or content awareness, and can lead to significant service disruption. To reduce service disruption latency, we propose a group-based CDN-P2P hybrid architecture (iCDN-P2P) with a location/content-aware selection of peers. Specifically, a SuperPeer network makes a location-aware peer selection by employing a content addressable network (CAN) to distribute channel information. It also manages peers with content awareness, forming a group of peers with the same channel as the sub-overlay. Through a performance evaluation, we show that the proposed architecture outperforms the original CDN-P2P hybrid architecture in terms of connection setup delay and media delivery time.

  • Purpose: The purpose of this study was 1) to examine levels of awareness on preconception care and pregnancy, and reproductive health promoting behavior among pre-honeymooners; and 2) to explore the relationship between awareness levels of preconception care and pregnancy, and reproductive health promoting behavior. Methods: This study was a correlation design with a total of 134 participants (67 couples of pre-honeymooners). Data were collected with questionnaire Results: Mean score of self-perception of awareness of preconception care and pregnancy was 2.82 out of 4. Content awareness level was 6.83 out of 13, and reproductive health promoting behavior score was 3.02 out of 4, indicating low to mid-level. Women reported higher scores in all variables than those in men. Self-perception awareness and content awareness of care and pregnancy had a weak positive correlation (r=.18, p=.038). Reproductive health promoting behavior was positively related to self-perception awareness of care and pregnancy (r=.33, p<.001) and content awareness of care and pregnancy (r=.23, p=.008). Conclusion: Based on this results, a variety of nursing intervention strategies may need to promote reproductive health behavior such as raising awareness of the preconception care and pregnancy.

  • 본 연구는 모션캡처 기반의 투영형 VR 시스템을 이용하여 환경 인식도를 개선하는 게임화의 유효성을 탐색하였다. 그 과정에서 긍정적 및 부정적인 VR 게임 콘텐츠의 주요 요소와 개인 플레이와 협동 플레이 방식이 지속 가능한 행동 촉진에 어떠한 영향을 미치는지 분석하였다. 연구 결과는 다음과 같다. 첫째로, 분리수거의 중요성에 대한 인식 개선에서는 개인 플레이 방식에서 긍정적 콘텐츠의 사용이 효과적임을 발견하였다. 둘째로, 환경오염의 심각성에 대한 인식 증진에서는 협동 플레이 방식에서 긍정적 콘텐츠의 사용, 개인 플레이 방식에서는 부정적인 콘텐츠의 사용이 각각 효과적임을 확인하였다. 셋째로, 개인 플레이에서 긍정적인 콘텐츠를 먼저 경험한 후, 부정적인 콘텐츠를 경험하는 것이 환경에 대한 관심 증가에 효과적임을 확인하였다. 이 연구 결과를 바탕으로, 환경 인식 개선을 위해 단순히 긍정적이거나 부정적인 콘텐츠만을 사용하는 것보다, 개선 대상에 따라 긍정적인 콘텐츠와 부정적인 콘텐츠의 사용 순서를 조절하는 것이 더 효과적임을 확인하였다. 또한, 분리수거의 중요성, 환경오염의 심각성, 그리고 환경에 대한 관심도를 모두 고려할 때, 개인 플레이 방식이 효과적이며, 각 척도에 따라 협동 플레이 방식이 더 효과적일 수도 있음을 확인하였다.

  • The effects of pressure cooker brand awareness, in terms of rice cooking performance, were evaluated using consumer acceptability tests. A blind test was performed using rice samples cooked by 3 different pressure cookers without any brand information, and a brand awareness test followed with the same informed consumer panel. Overall acceptability, glossiness, stickiness, hardness, flavor, and color were evaluated and compared to determine whether or not there were changes on consumer choice for acceptability. Brand A and brand B were not significantly different in their overall acceptability, moisture content, flavor, or color (p > 0.05), but they were significantly different for glossiness, stickiness, and hardness. Brands A and C were significantly different for all the attributes (p < 0.05). In the brand awareness test, brands A and B were not significantly different in their liking scores for all the attributes (p > 0.05). Brand C had significantly lower liking scores for overall acceptability, glossiness, stickiness, hardness, and moisture content than the other brands (p < 0.05). When comparing the liking scores for all the attributes with those of the blind test, the scores of the brand awareness test were slightly higher. For brand A, there were changes in its liking scores for overall acceptability, flavor, and glossiness (p < 0.05). However, brands B and C had brand awareness effects for all the attributes (p < 0.05).

  • The government has defined domestic violence as one of the four major social evils and tried to prepare laws and systems to prevent it. Nevertheless, domestic violence has emerged as a serious social issue, and compare to the number of domestic violence cases that are constantly increasing, the report rate of domestic violence is significantly lower. This suggests the need to improve citizens' perception of domestic violence as the issue to solve it together in society, not as a private matter at home. Most of existing contents for preventing domestic violence and improving awareness are simple viewing forms of video contents, which have little effect on recognition. We aim to confirm the possibility of improving social awareness about domestic violence by producing Virtual Reality (VR) contents that have great features of user's immersion and empathy. In this VR content, the user can interact with various objects in the virtual reality of domestic violence and directly or indirectly experience the victim's position. Users who view the violent environment from the victim's point of view can have a subjective empathy for the problem, which is expected to induce more active awareness about domestic violence.
