As time goes by, most of information escapes human being's memory even though he/she tries hard to remember the information. On the other hand, when a human being takes a look at an image, he/she recollects once forgotten past memories and relates a specific object in the photo with associated words, which trigger new memories. Beside, he/she feels the affection of that time by the recalled memory. Therefore, this paper proposes an augmented memory system that assists recollection of user's past memories by using the images in social network services and user's dictionary for associated words. In the proposed system, if a user selects an object in an image, words associated with the object is provided to the user. If the user selects one of the associated words, the proposed system offers the list of other images containing the object of the selected word. The repetition of the aforementioned process can make the user recollect his/her memory and stimulate his/her affection. It is expected that the proposed system will be useful for revitalizing social network services.

This study identified the impact of augmented reality advertising on attitude toward advertising and memory according to the type of presence and flow level. The presence (cognitive, emotional, media) and flow level (high vs. low) of the augmented reality(AR) advertising were set as independent variables and analyzed by Two-Way MANOVA. As a result of the research, first, the augmented reality advertising attitude was positive when the emotional presence and flow level were high. Second, when the flow level is high, the ARM such as product attribute information increases, but when the flow level is low, the evaluation-oriented GRM increases. Third, emotional presence increases GRM when the flow level is high, but ARM increases when the flow level is low. Fourth, the memory effect was low regardless of the flow level. In the future research, it would be desirable to produce augmented reality advertisements through virtual brands in the generalization of research.

최근 기존의 시청촉감 이외에 후각을 이용하려는 시도가 증가하고 있으며, 상용화에 접근하고 있다. 후각의 경우는 자주 사용되지는 않지만, 매우 강력한 기억과 연상 메카니즘을 제공하며 기존 감각의 극적인 증강효과를 제공할 수 있으며, 방송이나 인터넷에서의 미디어의 실감효과 뿐만 아니라 가상현실과 증강현실을 실제 현실처럼 느끼게 만들 수 있을 것이다. 이러한 후각 디스플레이 기술의 현황과 연구 및 표준화 방향을 소개하고 후각 디스플레이의 적용에 있어 고려해야 하는 문제 등을 정리하고자 한다.

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a common autoimmune encephalitis that is noted to be a severe but treatable disease entity. Patients with anti-NMDAR encephalitis often develop psychotic symptoms, including delusions, hallucinations, and paranoia, as well as memory impairment and persistent loss of attention. However, MRI findings in such patients show no abnormalities in most cases. Although typical brain abnormality features, known as T2 hyperintensities, involve the brain parenchyma and contrast enhancement at the cerebral cortex or overlying meninges, isolated leptomeningeal enhancement has been rarely reported in anti-NMDAR encephalitis. Herein, we report a patient with anti-NMDAR encephalitis who presented with isolated leptomeningeal enhancement, additionally showing the diagnostic value of contrast-enhanced fluid-attenuated inversion recovery imaging.

효과적인 백신 프로그램을 디자인하기 위해서는 질병과 면역에 대한 기본적인 이해가 필수적이다. 면역에 대해서 이해하기 위해서는 크게 체액성 면역과 세포성 면역으로 구분하여 이해하는 것이 유용할 수 있으며, 또한 이 두 가지 기전은 서로 상호협동적으로 작용한다는 사실을 이해하여야 한다. 숙주동물(닭)이 병원체이든 백신이든 일단 항원에 한 번 노출이 되면 이를 기억하는 기억 세포를 생성하여 두 번째 노출되었을 때 폭발적인 면역반응이 일어나도록 한다. 순환항체가 형성이 되면, 이 항체는 난황을 통하여 후대 병아리에게 전달될 수 있다. 면역의 형성은 백신이 가진 항원의 특성과 백신의 타입(생독, 사독)에 따라 다른 방식으로 나타난다. 면역에 대한 기본적인 개념을 충분히 숙지하고 다음의 사항을 고려하면 효과적인 백신 프로그램을 선택하기가 용이하다. (1) 전례 : 어떤 프로그램이 효과적이었는가? (2) 질병 : 어떤 질병이 문제가 되고 있는가? (3) 균주 : 균주의 차이는 중요한가? (4) 관리 : 백신의 사용을 불필요하게 할 효과적인 사양관리가 이루어질 수 있는가? (5) 모체이행항체 : 모체이행항체가 적절한 방어력을 가질 수 있을까? (6) 면역증강효과 : 그 중요성과 접종시기가 숙지되어 있는가? (7) 접종기술 : 접종기술에 문제가 있는데 프로그램이 제대로 효과를 발휘할 수 있을까?

In the present study, we examined the effect of the aqueous extract of Rubus coreanus Miquel (RCM-Ex) on scopolamine-induced memory impairment in male ICR mice. Mice were fed the diet containing 100 mg/kg body weight/day of RCM-Ex for 4 weeks. To induce amnesia, scopolamine (an antagonist of muscarinic acetylcholine receptor, 1 mg/kg of body weight) was intraperitoneally injected into mice 30 min before starting the behavior tests. RCM-Ex reversed scopolamine-induced memory impairments in mice as evidence by the passive avoidance test and Morris water maze test. In addition, acetylcholineasterase activities were decreased in the brains of mice treated with RCM-Ex. These results suggest that RCM-Ex may be an effective agent for the prevention of the memory impairment induced by cholinergic dysfunction.

People live in their everyday life busy with studies, part-time jobs, and searching for an ideal job. In their busy routine, they try to find time for themselves and expose their emotions through diverse social network services(SNS). We made a service that we can plant a virtual tree in places we daily visit and go by. You can keep note on the virtual tree and look through the past records. It is a reality based mobile application service that can be used like a diary.In this project we chose the tree as the metaphor and tried to express time passing in a specific place. As our memory is a part of our daily life, we emphasized the meaning of space important.

In an ever-changing tourism environment, we need to think about how to successfully attract tourists and provide them with memorable experiences. Smart tourism content is considered as a useful tourism resource for converting into an attractive tourist destination by providing new values in various tourist destinations as well as the changed tourism patterns due to COVID-19. However, there are still few successful cases of smart tourism contents that have secured economic sustainability. Accordingly, this study applied the Contingent Valuation Method (CVM) to estimate the economic value perceived by tourists for smart tourism contents based on augmented reality to develop a smart tourism content development plan that can secure economic sustainability. As a results, it was confirmed that the lower the offered amount, the higher the awareness of the new value, the higher the likelihood of willingness to pay. Based on these research results, this study presented academic and practical implications for the development of smart tourism content that secured economic sustainability.

Recently, with the development of digital, children are exposed to a lot of media media. Reading activity decreases, making it difficult to acquire information from books or organize and remember acquired information. Since education with augmented reality increases children's participation and immersion in learning, we proposed a reading activity application with augmented reality technology to increase children's reading interest and creativity. In addition, based on the five nurturing processes, we designed a play-oriented reading activity for the application. In addition to the application suggestions, we designed a play-centered lesson model so that it can be used in actual lessons. In order to analyze the conceptual thinking framework according to the lesson model design, we visited an actual daycare center and conducted a class attended by an expert. Experts who participated were asked to fill out a pre-produced questionnaire to review the suitability of the reading activity class model and operation, and the feasibility was examined. Our lesson model design was based on limited book content, and due to ethical concerns, large-scale experiments with children could not be conducted, so the results of the study are not representative of the whole. However, it is significant that the possibility of running a new reading activity class based on the Nuri course has been examined and proposed.
