A gas sensor, comprised of both ZnO and $PdCl_2$ powders, has been developed to sense the CO gas of low concentration (100 ppm). When the weight ratio of ZnO/$PdCl_2$ element sintered at $600^{\circ}C$ was 99.5/0.5, the maximum sensitivity to CO gas was obtained at the operating temperature of $200^{\circ}C$. Also, the response characteristics of this element were examined, and then the response time was decreased from 90 to 45 sees, with operating temperature increase in the range of $100-400^{\circ}C$.

미래 전장환경이 네트워크 중심으로 변해감에 따라, 워게임 시뮬레이터는 네트워크에 분산된 모듈간의 높은 상호운영성과 전장 이벤트에 따른 동적구성의 필요성이 높아지고 있다. 본 논문에서는 이벤트 기반의 워게임 시뮬레이터 개발방법론을 제안한다. 워게임 시뮬레이터의 페더레이트들은 이벤트 기반의 웹서비스로 개발되며, 각 페더레이트는 전장 이벤트를 감지하고, 관계있는 이벤트가 발생할 경우에만 워게임에 반응하게 된다. 이러한 감지-반응 방법과 비동기적 이벤트 처리방법을 이용하여 시뮬레이션 수행 시간을 줄일 수 있다. 본 논문에서는 간단한 수상전 시뮬레이터를 구성하여, 제안된 방법이 전장 장비 및 네트워크상에서 모델러 및 운영자를 통해 발생되는 다양한 이벤트를 처리해야 하는 미래 전장환경 시뮬레이션 수행시 효과적임을 보이도록 한다.

Ranking thousands of web documents so that they are matched in response to a user query is really a challenging task. For this purpose, search engines use different ranking mechanisms on apparently related resultant web documents to decide the order in which documents should be displayed. Existing ranking mechanisms decide on the order of a web page based on the amount and popularity of the links pointed to and emerging from it. Sometime search engines result in placing less relevant documents in the top positions in response to a user query. There is a strong need to improve the ranking strategy. In this paper, a novel ranking mechanism is being proposed to rank the web documents that consider both the HTML structure of a page and the contextual senses of keywords that are present within it and its back-links. The approach has been tested on data sets of URLs and on their back-links in relation to different topics. The experimental result shows that the overall search results, in response to user queries, are improved. The ordering of the links that have been obtained is compared with the ordering that has been done by using the page rank score. The results obtained thereafter shows that the proposed mechanism contextually puts more related web pages in the top order, as compared to the page rank score.

Clothing is high-involvement products which is closely related with human being both physically and psychologically. It is the prod-uct bought by consumer repeatedly and needs lots of information according to the changing of modes. The comsumer is very sensitive to the advertisement when they purchase the clothing products. Therefore the importance of the advertising is remakably emphasized in these days. According to the qualitative and quantitat-ive growth of advertisement the unique mar-keting strategy must be deviced that is differ-ent from the past. This thesis focuses onthe importance of afection which is more pre-ferred when consumer contacts the advertise-ment. And this study purposes on the provid-ing the basic data to plan effective clothing advertisement by way of analyzing how atti-tude-forming affects the purchase intend of the comsumer. The findings of the study are as follows. 1. Sense-pursuit tendency is strongly ap-peared among the low-age not-married groups. 2. By the factor analysis of consumer re-sponse in each advertisement 5 factors proved to be valid ones 3. There were significant differences be-tween the brand-used and advertisement ex-perienced customers according to the adver-tisement/brand attitudes. 4. There were no significant differences be-tween the application of clothing advertise-ment and demographic character. 5. The affective response more affects on cognitive response and purchase intend in 4 modes of advertisement. 6. From the pathes of the brand-used experi-enced to purchase intend the characteristics showed up in each advertisement.

In 2020 when the COVID-19 pandemic began in full-scale, the WHO Director-General warned of the dangers of an infodemic. The infodemic is a phenomenon in which false information spreads rapidly like an epidemic and causes chaos, and it was noted that the COVID-19 pandemic is not just limited to health problems, but also linked to a variety of issues such as human rights, economic inequality, various discrimination, hate speech, fake news, global governance etc. In the field of education, it is necessary to think about how to connect this global situation with school classes. Accordingly, this study suggested the direction for global citizenship education by analyzing how the infodemic spreads on Korean social media with the case of the recent global COVID-19 pandemic. According to the research results, the rate of negative emotions was higher than positive ones in the emotions that generate infodemic, while anxiety and anger were focused among negative emotions. In addition, the infodemic tended to spread widely with the feelings of anger rather than anxiety, and the feelings of anger led to advocating aggressive policies against certain country and regions. Therefore, global citizenship education is required to focus on a sense of duty and responsibility as a citizen, not on the level of national identity based on an exclusive sense of belonging. Furthermore, global citizenship education needs to lead to presenting a blueprint for education in a way that can enhance the awareness of the global community for joint response to global challenges and realize common prosperity based on sustainability and justice.

Objective Sweet bee venom is made by removing allergen from the bee venom through gel filtration chromatography and propionic acid/urea polyacrylamide gel electrophoresis. The aim of this study was to verify allergy inhibitory action in Sweet Bee Venom(SBV) and New Sweet Bee Venom(NSBV) removed enzymes and compounds of low molecular weight. Methods 84 healthy adult men and women were selected through a survey whom had never received the bee venom therapy in the past. The concentration of Normal Saline, SBV and NSBV pharmacopuncture was equally at 0.1mg/mL and the experiment was conducted as the double blind test. Results Participants of the study was comprised of 63 men and 21 women with the average age of 28.3 years. According to results of pain sense, SBV group showed significant higher score compared with NS group and NSBV group using VAS in treating time. And SBV and NSBV group showed significant higher score compared with NS group after 30 minutes. Other allergic responses were insignificant between the groups. Conclusions As a result of removed allergen and compounds of low molecular weight, NSBV significantly inhibits pain sense in treating time compared with SBV. This indicates wider and easier application of NSBV for the useful application in clinical treatment. Further comparative studies should be conducted to yield more objective verification.

Regulation of feeding is essential for animal survival. The pharyngeal sense organs can act as a second checkpoint of food quality, due to their position between external taste organs such as the labellum which initially assess food quality, and the digestive tract. Growing evidence provides support that the pharyngeal sensory neurons regulate feeding, but much is still unknown. We found that a pair of gustatory receptor neurons in the LSO, a Drosophila adult pharyngeal organ which expresses four gustatory receptors, is involved in feeding inhibition in response to high concentrations of sodium ions. RNAi experiments and mutant analysis showed that the gustatory receptor Gr2a is necessary for this process. This feeding preference determined by whether a food source is perceived as appetizing or not is influenced by nutritional conditions, such that when the animal is hungry, the need for energy dominates over how appealing the food source is. Our results provide experimental evidence that factors involved in feeding function in a context-dependent manner.
