This study was executed to develop an education program, which improves knowledge for dementia prevention of the middle aged and enhances positive attitudes, and provide basic data that can apply to communities by inquiring into the middle aged's dementia knowledge, attitudes and needs for dementia prevention education. The study data were collected from 218 people aged 40 to 64 in N city from October 15th to November 30th 2018. For data analysis, frequencies and percentages, t-test, ANOVA, Scheffé test and Pearson's correlation coefficients were applied. The study result displayed that the score of the middle aged's dementia knowledge was above average(9.13±2.20). The question 'Dementia is a disease.' earned the highest percentage of correct answers(88.1%), whereas the question 'Dementia is caused by medical, neurologic or psychiatric disorders.' earned the lowest percentage of correct answers(30.3%). The scores of attitudes towards dementia(34.33±5.69) and needs for dementia prevention education(23.58±3.46) were above average. In addition, there was a statistically significant positive correlation between attitudes towards dementia and needs for dementia prevention education(r=.275, p<.000). In conclusion, it was revealed that positive attitudes towards dementia had a close relation with needs for dementia prevention education. These findings implies that there will be a need to develop a systematic education program about dementia for the middle aged and seek proper political improvements of dementia through cooperation between communities and the country.

This study intends to develop an eco-friendly concrete panel mixed with biochars. Experiments about mechanical and thermal properties were conducted on porous biochar concrete, which has insulation and carbon-capture performance. The concrete has a mixing ratio of 0, 5, 10, and 15 % for biochar and a water-binder ratio of 0.35. The unit weight, porosity, and permeability were measured to evaluate the mechanical characteristics. From the results, as the biochar mixing rate increased, the porosity and the permeability increased, but the unit weight decreased. Even though a decreased trend was observed in the compressive strength results, they satisfied the design standard. Since the thermal conductivity was decreased during the increase of contents, biochar could be considered an excellent material for insulation performance. In addition, regression analyses were conducted regarding the relationship of unit weight with porosity, compressive strength with thermal conductivity, and porous with thermal conductivity. From the regression, significant variables for expanding the scope of the application of biochar were presented.
The Global Expansion Roadmap published by the International Space Exploration Coordination Group, which is organized by space agencies around the world, presents future lunar exploration guidance and stresses a lunar habitat program to utilize lunar resources. The Moon attracts attention as an outpost for deep space exploration. Simulating lunar surface environments is required to evaluate the performances of various equipment for future lunar surface missions. In this paper, an experimental study was conducted to simulate high vacuum pressure and cryogenic temperature of the permanent shadow regions in the lunar south pole, which is a promising candidate for landing and outpost construction. The establishment of an efficient dirty thermal vacuum chamber (DTVC) operation process has never been presented. One-dimensional ground cooling tests were conducted with various vacuum pressures with the Korean Lunar Simulant type-1 (KLS-1) in DTVC. The most advantageous vacuum pressure was found to be 30-80 mbar, considering the cooling efficiency and equipment stability. However, peripheral cooling is also required to simulate a cryogenic for not sublimating ice in a high vacuum pressure. In this study, an efficient peripheral cooling operation process was proposed by applying the frost ratio concept.
Since 2009, stars produced through audition programs have appeared through the process of establishing familiar ties with viewers, unlike stars created by entertainment agencies. This study is a case study that examines the characteristics, roles, and identity of internet live broadcasts (Labang) of vocalists Kang Dong-hoon and his fan cafe(fan community) who appeared in JTBC Phantom Singer 3 in 2020. As a result of the study, fans gathered around SNS even before the fan cafe was created, at their request, 'Labang' began. "Labang" is a "freely participating talk show" in which fans actively participate. This brought about the bond of fans, a sense of belonging, and the activation of fandom. Both stars and fans recognized "Live Broadcast" as "a window of communication to get to know each other," and expressed satisfaction that they could see the sincerity of familiar and unpretentious stars, not unrealistic images reproduced on TV through "immediate comment communication." "Labang" consists of a variety of contents, including stars' daily lives, music activities, broadcast appearances, and hobbies, and is showing "aesthetic differentiation" from those who do not watch "Labang" while sharing the daily lives of stars and fans with active participation.
The restoration of cultural heritage materials is an important research theme. This study improved the existing cultural heritage restoration method and attempted to establish a restoration system for cultural heritage data based on historical documents and visual materials. Recognizing the limitations of existing studies, this paper attempted to restore cultural heritage data through interdisciplinary research. In addition, 3D restoration was carried out after restoration in 2D form based on literature documents rather than existing visual sources. The object of restoration that was selected was "Jeol," which represents the power of the king of Koguryo. Koguryo's Jeol is a type of flag. Jeol appears in the mural in Anak Tomb No. 3. Rather than using only photographic materials of murals, the restoration was carried out through cross-validation of literature data and materials on archaeological art history. This is important in that the restoration carried out in this study is an accurate restoration with a historical understanding based on the literature of the relevant cultural heritage. In this study, a restoration process based on historical records was established. A 3D restoration process was performed by adding and applying visual materials after the object was first shaped based on the literature data. Restoration based on literature and visual materials was carried out based on interdisciplinary research. Therefore, this study aims to build a digital restoration system for cultural heritages and to contribute to spreading the 3D digital restoration research of cultural heritages that can be applied to various platforms.

The purpose of this study is to examine the perception of librarians on the role of public libraries related to disasters. For this purpose, the study conducted an online survey for librarian. The survey is composed of 34 questions, including the questions asking librarians' perceptions about the roles of public libraries related to the disasters derived from literature review. The research results are as follows; First, although librarians were not well aware of the roles of public libraries related to disasters, they generally supported the necessity of the role and evaluated the benefits of the role highly. Second, librarians recognized the necessity of the role of the library in the following order of importance; psycho-emotional support for citizens who have experienced disasters; cooperation with disaster support agencies; disaster shelter; disaster information service; archiving disaster experiences of residents; outreach services; community support. Third, librarians recognized that psycho-emotional support services for residents suffering from disasters were the most necessary and beneficial to residents. Fourth, librarians' perceptions of disaster-related library roles changed based on their position and the type of library they belong to. On the basis of these results, the research discussed and suggested what roles each public library should play and what services it should plan, and how it should be implemented during the disaster.

This study increases awareness of the survey and demand for libraries in correctional facilities, which have not received much attention so far, and is necessary for improving the operation of existing research and libraries in Korea, which is conducting a current status survey of most correctional facility libraries. The contents of the service operation of the external correctional facility library were explored and analyzed. As a result of the analysis, the United States, the United Kingdom, and Germany, where correctional facility libraries are relatively well operated, are practically operating social rehabilitation programs while reducing recidivism of inmates, and library associations or local governments in each country are promoting the vitalization of correctional facility libraries. It helps and organizes committees or organizations involving related experts to discuss policy support, issue checks, research, report publication, drafting and revising guide guidelines, cooperation between libraries, and reflect them in actual operation. In addition, it maintains steady support and interest through public-private cooperation, and makes good use of the linkage system with local public libraries. As a result, it contributes to reducing the recidivism of prisoners. Through this study, the following three areas were suggested for the administrative improvement direction for correctional facility library services. First, the production and distribution of guidelines or guidebooks for correctional facility libraries, second, the establishment of a specialized correctional facility library organization within the correctional headquarters or library association, and third, the strengthening of activities and the operation of law libraries in correctional facilities.

Maruca vitrata is one of important pests in leguminous crops, especially red bean. We investigated the effects of temperature on development of each life stage, adult longevity and fecundity of M. vitrata for understanding the biological characteristics of the insect species at eight constant temperatures of 13, 16, 19, 22, 25, 28, 31, and 34℃. Eggs hatched successfully at all temperature subjected and larvae successfully developed to the adult stage from 16℃ to 31℃. The developmental period of egg decreased up to 31℃ and after then increased. The developmental period of larva and pupa, and adult longevity of M. vitrata decreased with increasing temperature. Lower and higher threshold temperature (TL and TH) were calculated by the Lobry-Rosso-Flandrois (LRF) and Sharpe-Schoolfield-Ikemoto (SSI) models. The lower developmental threshold (LDT) and thermal constant (K) from egg hatching to adult emergence of M. vitrata were estimated by linear regression as 12.8℃ and 280.8DD, respectively. TL and TH from egg hatching to adult emergence using SSI model were 14.2℃ and 31.9℃. Thermal windows, i.e., the range in temperature between the minimum and maximum rate of development, of M. vitrata was 17.7℃. In addition, we constructed the oviposition models of adult, using the investigated adult traits including survival, longevity, oviposition period and fecundity. Temperature-dependent development models and adult oviposition models will be helpful to understand the population dynamics of M vitrata and to establish the strategy of integrated pest management in legume crops.

The researcher has examined about the infrastructure of geotourism industry as well as domestic and foreign literatures in order to see the future and present status of geotourism in our country. The researcher have concluded the followings after participating in the interpretive program of Taean haean(coastal) National Park, etc. which is thought to as having relatively well-prepared contents and education in addition to the active progress of the program especially. First, although the domestic infrastructure of geotourism is thought as relatively well-established, one needs to make up for the weak point that there are not enough editions of explanations related to land formation process and geological aspects. Second, the interpretive program operated by The Korea National Service Park needs to specialize what the program is all about, how it is operated, who is operating, and so on in order to bring subjects' characteristics into relief. Third, one needs to train the persons required to explain geomorphic landscape and geological features by establishing the new division of education of geomorphic landscape and geological features. Furthermore, one needs to set up a unit to take charge of geotourism within the central and local governments. Fourth, one needs to build the cooperative system of private-public-academic circles among private companies, government, and universities to promote the quality of interpretive program by close connections with related studies of geography and geology. Fifth, the vitalization of geotouriusm can make an enormous contribution to promote the nation's brand value and image by advertizing domestic beautiful landscapes of the nature in addition to creating new job markets. Thus, the financial support in the government level should be made. Sixth, one needs to dig out global resources of geotourism unique to us by developing the stories connecting with local cultures and histories.
