Temperature and humidity data collection using real-time sensors and data loggers was conducted for integrated pest management in the collection storage and exhibition space of the Jeongnimsaji Museum, Buyeo. The real-time temperature and humidity monitoring system collected measurement data every 30 minutes and enabled real-time confirmation of the data through a linked application. If the temperature and humidity data measured in the real-time temperature and humidity monitoring system exceeds the set range, a push notification was sent to the mobile phone of the person in charge to provide status information to establish a continuous management system. Through this, it was possible to immediately recognize and take action when the temperature range exceeded the recommended relic temperature in August. We performed data visualization on the concentration of airborne fungus in the storage area and the inflow path and density of insects. Based on the recommended criteria presented by the National Institute of Cultural Heritage, The data on the spatial and temporal concentration of airborne fungus inside the collection storage were found to be maintained at a value below the standard recommended by the National Institute of Cultural Heritage (80 CFU/m³). Also, as a result of the insect inflow survey, no insects were captured inside the storage area, and in the case of the exhibition space, insects such as Scutigera coleoptrata, Loxoblemmus arietulus, Diestrammena asynamora, Koreoniscus racovitzai were captured. Based on this, as a result of visualization according to the individual density of captured insects by area, it was confirmed that the main inflow paths of insects were the external entrance and the toilet area.

The purpose of this study is to verify the path of the motivation, the flow, and problem gambling and intervention points. To this end, we verified the mediation effect of the motivation of the users outside sales offices influences the problem gambling through a flow and the moderated mediation effect of the frequency of the use of a bicycle racing tracks in that process. A total of 411 cases were analyzed using surveys conducted for one day on a weekday and weekend (September 13th and 15th 2018) for adults using an outside sales office in Jangan. According to the analysis, the causality of gambling by gambling motivation(amusement, excitement, avoidance, society, money) showed its effect positively by mediating the flow. The adjusted effect of the frequency of the use on the intermediary effect of the motivation ${\rightarrow}$ flow ${\rightarrow}$ problem gambling behavior, which is the main concern of this study, was found to be statistically significant. More specifically, the effect of adjusting the frequency of the use was statistically significant in both paths: motivation/flow and flow/problem gambling. It was also shown that, in the model with excitement, avoidance and social motivation, the adjustment of the frequency was only significant in the causal relationship between the flow and problem gambling. Based on these findings, this study made clinical and policy suggestions for intervention for gamblers and user protection regulations.

Modules using 6 inch cells have problems with loss due to empty space between cells. To solve this problem made by shingled structure which can generate more power by utilizing empty space by increasing the voltage level than modules made in 6inch cell. Thus, in this paper, the c-Si cutting cells were produced using nanosecond green laser, and then the ECA was sprayed and cured to perform cutting cell bonding. Three types of ECA materials (B1, B2, B3) with Ag as the main component were used, and experimental conditions varied from 5 to 120 seconds of curing time, 130 to $210^{\circ}C$ of curing temperature, and 1 to 3 of curing numbers. As a results of experiments varying curing time, B1 showed efficiency 19.88% in condition of 60 seconds, B2 showed efficiency 20.15% in 90 seconds, and B3 showed efficiency 20.27% in 60 seconds. In addition, experiments with varying curing temperature, It was confirmed highest efficiency that 20.04% in condition of $170^{\circ}C$ with B1, 20.15% in condition of $150^{\circ}C$ with B2, 20.27% in condition of $150^{\circ}C$ with B3. These are because the Ag particles are densely formed on the surface to make the conduction path. After optimizing the conditions of temperature and curing time, the secondary-tertiary curing experiments were carried out. as the structural analysis, conditions of secondary-tertiary curing showed cracks that due to damp heat aging. As a result, it was found that the ECA B3 had the highest efficiency of 20.27% in condition of 60 seconds of curing time, $150^{\circ}C$ of curing temperature, and single number of curing, and that it was suitable for the manufacture of Solar cell of shingled structure rather than ECA B1 and B2 materials.

Big Data has spread rapidly in various industries since 2010. We analyzed the general characteristics of big data through time series analysis on the initial process of spreading big data and investigated the difference of diffusion characteristics in each industry. By analyzing papers, patents, news data, and Google Trend using Big Data as a keyword, we searched for data corresponding to the leading indicator, and confirmed that trends in news and Google Trend preceded the papers and patents by two years. We used Google Trend to compare the introduction period of domestic, US, Japan, and China and quantify the process of spreading the eight main industries in Korea through news data. Through this study, we present an empirical research method on how the general technology spreads in several industry sectors and we have figured out where the spreading speed difference of big data originated in each industry in Korea. The method presented here can be used to analyze the technology introduced from foreign countries in developing countries because it can be analyzed in diffusion process of other technologies besides big data and corresponds to the diffusion of technology keywords in a specific country. And, on the corporate side, this approach shows what path is effective when it comes to launching and spreading new technologies.

What is unknown about Leibniz (Gottfried Wilhelm Leibniz, 1646~1716), a great philosopher and mathematician, is that he inquired about ginseng. Why Leibniz, one of the leading figures of the Enlightenment, became interested in ginseng? This paper excavates Leibniz's references on ginseng in his vast amount of correspondences and traces the path of his personal life and cultural context where the question about ginseng arose. From the sixteenth century, Europe saw a notable growth of medical botany, due to the rediscovery of such Greek-texts as Materia Medica and the introduction of a variety of new plants from the New World. In the same context, ginseng, the renowned panacea of the Old World began to appear in a number of European travelogues. As an important part of mercantilistic projects, major scientific academies in Europe embarked on the researches of valuable foreign plants including ginseng. Leibniz visited such scientific academies as the Royal Society in London and $Acad{\acute{e}}mie$ royale des sciences in Paris, and envisioned to establish such scientific society in Germany. When Leibniz visited Rome, he began to form a close relationship with Jesuit missionaries. That opportunity amplified his intellectual curiosity about China and China's famous medicine, ginseng. He inquired about the properties of ginseng to Grimaldi and Bouvet who were the main figures in Jesuit China mission. This article demonstrates ginseng, the unnoticed subject in the Enlightenment, could be an important clue that interweaves the academic landscape, the interactions among the intellectuals, and the mercantilistic expansion of Europe in the late 17th century.

In spite of a few numbers of Hyangga that is handed down today, Hyangga has diverse and abundant contents. So it is possible to survey Hyangga as a journey literature of the middle age. On this purpose we can inquire into the Hwarangs' group journey, because the Hwarang was one of the main enjoying group of Hyangga. Hwarangs' group journey shows many aspects. They made a journey for the public purpose like a tour of inspection of people's daily life and the fortresses of the country's peripheral areas. Also, they made a journey for personal purposes like enjoying the attractive view of the mountains and rivers or seeking pretty girls outside of the palace. On these journeys, Hwarang made and enjoyed Hyanggas. Among Hyanggas that remains today, Hyeseongga and Cheoyongga have a direct relation to Hwarang's journey. Hyeseongga was made to eliminate the calamities that occurred at the time of the start of a journey. It is expressed in this poem that Hwarang could take a peaceful trip with the condition that the celestial objects shed light on the earth path. As such, the trip becomes a sacred ceremony. Cheoyongga reflects the fact that the foreigner Cheoyong became Hwarang and toured the streets of Seorabeol, the capital of Shilla. The Cheoyong's bitterness of broken love is expressed in this poem. SongSadahamga and MoJukjirangga come under a broad category of Hwarang's journey literature. SongSadahamga is a farewell poem for Hwarang who leaves to fight on the battlefield. It was universal to make a journey for the fighting of a battle in Shilla period, so many Hyanggas would be made under those situations. MoJukjirangga has the content of Hwarang's trip for saving his follower who was taken by another senior. It expresses the intimate relationship between Hwarang and the follower. Though the words of the song have not been remained, Hyeongeumpogok, Daedogok, and Mungungok were created on the way of Hwarang's journey. These seem to be a series poems which have the proper characteristic features of the Hwarang's journey literature. In these poems, the king's open mind and liberal political views are reflected. In short, Hwarang created and enjoyed Hyanggas on the way of their journey, so Hyangga has the features of journey literature in Korean middle ages.

The purpose of this study is to examine the mediating effect of depression on the relationship between assets and life satisfaction in Korean elderly (45 years old or older). To this end, we used the data from the KReIS 5th Main Survey (2013). SPSS 21.0 and AMOS 25.0 were used for data analysis. The analysis methods were descriptive statistical analysis, correlation analysis, regression analysis and path analysis. As a result of the analysis, first, the assets of middle-aged and old age had a negative effect on depression, and the depression had a negative effect on life satisfaction. Second, the assets of the elderly have a positive effect on the satisfaction of life. Third, the effects of assets on the satisfaction of life were found to be mediated by depression of middle-aged people. Based on the analysis results, this study suggested the introduction of middle age generation's asset formation support program, the universal implementation of basic pension for the elderly generation, and the gradual increase in benefits.
