This study analyzed the content of national-level curriculum documents for the purpose of reviewing the overall status of population education in elementary and secondary schools in South Korea. Based on the results of the analysis, directions for the future of population education at school were proposed. Both the 2007-Revised Curriculum and the 2009-Revised Curriculum contain the contents of population education as a 'Cross-curricular learning topic' in the general curriculum influenced by the low birth rate and ageing society, yet not in the current 2015-Revised Curriculum. Furthermore, when the curriculum documents for the ten common subjects corresponding to the 'National Common Basic Curriculum' proposed by the 7th Curriculum were examined, only 'Home Economics' curriculum at the secondary school level and 'Social Studies' curriculum at the elementary and the secondary school levels adequately reflected the subject goals, characteristics, contents and achievement standards that correspond to those of population education. Based on the results of the curriculum analysis, the following five directions for population education at school are drawn. First, the purpose of population education at school should be stated using gender-neutral terms of 'response to low-birth and aging society' and it has to be emphasized that it is not to intervene in natural childbirth. Second, the subject which deals directly with the goals, content elements, and achievement standards of population education should be designated as the leading subject for population education. Third, with its inter-disciplinary nature, population education should be able to provide quality contents for convergence education. Fourth, the government should provide policy support to the leading subjects for population education so that more high schools may select the subjects as elective courses. Fifth, teacher education should be improved to enhance teachers' perceptions on population. This study asserts that 'Home economics,' which deals with human daily lives, is an optimal subject that can reflect population education in connection with real life. To this end, policy support should be provided for 'Home economics' so that it may fulfill the mission as a leading subject of population education.

EuiJae Hu BaekRyun is a symbol of Honam Namjonghwa and is respected as a teacher of Honam culture. He is from JinDo and is a relative of Sochi Heo Ryun and a disciple of Misan Heo Hyeong. The spirit of traditional Namjongghwa and the dignity of painting faithful to its technique have been obtained by themselves, and have made it his own. EuiJae organized a 'Yeonjinhoe' in Gwangju to raise his students. After liberation, a house was built under Mudeungsan Mountain. And showed another aspect as a social educator who emphasized and practiced national spirit while being a tea ceremony man. He excelled in Chinese poetry and painting theory, and expressed a unique field in calligraphy. especially worked as an artist good at poetry, caligraphy, and painting. EuiJae showed exceptional talent, especially in landscape painting. His tendency to paint was to follow Ye Chan's technique of drawing with a dry brush, placing importance on the energy of learning, and constantly trying new experiments with the technique of gisaeng. The world of EuiJae's works can be divided into three periods, based on the signature using the trend of painting or the change of perspective pursued, the era of EuiJae, the era of EuiJaeSanin, and the era of EuiDoin, which had a tendency of independent painting. EuiJae's contribution surpassed the artistic historical assessment that he had formed a big stem for the authentic Namjongghwa of Korean painting culture, which was part of Oriental painting. And recognizing that he was a fundamental teacher connecting modern times through the actual scenery based on NamDohwa's universal spirit and regional characteristics and the creative succession of emotions, he should inherit his passion for artistic spirit and tradition and experimental spirit.

Cordyceps is a traditional Chinese medicinal herb well-known in China, Korea and Japan since B.C. 2,000. The original entomopathogenic fungus, Cordyceps sinensis belonging to the genus Cordyceps could not be found inside Korean peninsula due to the absence of the host insect for the corresponding entomogenous fungus. The development of artificial production methods of Korean type Cordyceps using the silkworm Bombyx mori as in vivo culture medium for the the entomopathogenic fungus Paecilomyces tenuipes is the first, and wonderful occasion in the research history of insect industry of this global world. The aim of this article is to review the historical research background, mass-production methods, and pharmacological effects of the silkworm-dongchunghacho (Paecilomyces tenuipes) which is a newly developed Korean medicinal insect-borne mushroom, and another non-insect-borne medicinal mushroom (Cordyceps militaris and Cordyceps pruinosa). Their biological actions include anti-tumor, immunostimulating, anti-fatigue, anti-stress, anti-oxidant, anti-aging, anti-diabetic, anti-inflammatory, anti-thrombosis, hypolipidaemic and insecticidal effects. The bioactive principles are protein-bound polysaccharides (hexose, hexosamin), cordycepin, D-manitol, acidic polysaccharide etc. Protein-bound polysaccharides and n-butanol fractions were demonstrated to show a significant anti-tumor activities but did not show a cytotoxicities. D-mannitol exhibited a significant prolongation of the life span in tumor bearing mice. Ergosterol did not show an efficient anti-tumor activity, but showed a significant phagocytosis enhancing activity. Anti-tumor activity of silkworm-dongchunghacho might be attributed to immuno-stimulating activities rather than cytotoxic effects [164]. Also this review comprises the breeding of Dongchunghacho varieties, optimization of culture conditions, improvement of learning and memory by Dongchunghacho, application of them as foods and chemical constituents.

Changam, Lee Samman(1770~1845), who created his own handwriiting to be referred to as the three great writers of the late Joseon Dynasty, invented as the original 'Haengunyusu Typeface' and developed Calligraphy spirit of DonggugJinche in Honam province. He ultimately pursued the state of tonglyeong by raising the personality of 'writing is the person's personality' and the attitude of learning the old. Through the book chang-amseogyeol, he basically polished Haeseo of Han Dynasty and Wi Dynasty and emphasized that Haengseo and Choseo are done automatically when muscle strength and bone strength are established. And since calligraphy originated from 'nature', it goes through the 'Beobcheongwijin' spirit. After doing so, expressed the state of tonglyeong of " mubeob-ibeob ", the stage of reaching. In addition, Changam showed the aesthetic that you can get the novelty by pursuing the philosophy of 'Wu' and the 'beauty of Stupid and Lacking' based on LaoTzu and ChuangTzu. This is a philosophy that follows nature's logic to reveal nature's nature. And it is an aesthetic that protects his 'True Wu' without knowing and greedy. On the other hand, Changam promoted natural and vital beauty through force in the method of using the brush. He suggested the 'Push and Hard' of the Han dynasty, pushing it with force using this power properly. In particular, the feeling of an IlunMujeog brush in 『Changam Calligraphy-The cloud stays Poem』 overflows with the vitality and bizarre and strange dynamism of the spirit and typeface as eum-yang harmonizes with each other. In addition, the beauty of Push and Hard containing polyeoghamse is misaligned, but it has achieved a natural aesthetic without invading. This work demonstrates the real look of Changam choseo. In addition, the beauty of Push and Hard containing polyeoghamse is misaligned, but it has achieved a natural aesthetic without invading. Changam proves the real look of "Haedong's best Chose Maestro".

The art of the Confucian literati' was mainly centered on literati' painting. Literary paintings combined with poem-writing-painting are based on the literary characters and studies. This is usually based on the technique of Shensi(神似) caused by a hobby accomplishment, enjoying the chinese painting and cherishing with chinese painting. The Confucian literati' cultivated their own character and sublimated humanism to art based on studying. They sought the life of supremacy and supreme gentleness, and enjoyed life on the boundary of pleasure through art. The aim of the Confucian literati' arts lies in the pursuit of expressing the artist's inner world, spirit, and the combination of the Confucian and the Taoism, Because of literati's spirit based on learning, the Confucian literati' arts still exist. The aesthetic of Sunbi Spirit is mainly in the customs of Sunbi, the loyalty of Sunbi, the Silhak(實學) of Sunbi, and loving of the people of Sunbi. We can find honor and loyalty in the Sunbi spirit of the Confucian literati' of the Joseon Dynasty. In addition, it is also possible to observe the loyal troops, the hard work for the country, and the Pung-ryu with nature. In other words, the Sunbi honor, loyalty, loyal troops, pursuit of study and the Pung-ryu show the spirit of the Confucian literati' of Joseon Dynasty. The aesthetic of the Sunbi spirit is in Pung-ryu, loyalty, Silhak, loving of the people etc. The aesthetic of experience of art is mainly based on the aesthetic experience by emotional intelligence and the aesthetic experience according to the individual's inclination. The aesthetic sense actually shows Pung-ryu, loyalty, Silhak and love etc. We can see it in many of our literary paintings. Therefore, the Confucian literati' painting in Chosun Dynasty were the intentionality of the mind and the intentionality of the spare. Furthermore, it has directivity of expressing the artist's inner world, directivity of substance, so it is possible to see that the characteristics of the Sunbi spirit are diverse.

With the changes in the future educational environment, such as the rapid decline of the school-age population and the expansion of students' choice of curriculum, changes are also required in PCK, the expertise of science teachers. In other words, the categories constituting the existing 'consensus-PCK' and the characteristics of 'science PCK' are not fixed, so more categories and characteristics can be added. The purpose of this study is to explore the potential area of science PCK required to cope with changes in the future educational environment in the form of 'Family Resemblance Science PCK (Family Resemblance-PCK, hereafter)' through Wittgenstein's family resemblance approach. For this purpose, in-depth interviews were conducted with three focus groups. In the focus group in-depth interview, participants discussed how the science PCK required for science teachers in future schools in 2030-2045 will change due to changes in the future society and educational environment. Qualitative analysis was performed based on the in-depth interview, and semantic network analysis was performed on the in-depth interview text to analyze the characteristics of 'Family Resemblance-PCK' differentiated from the existing 'consensus-PCK'. In results, the characteristics of Family Resemblance-PCK, which are newly requested along with changes in role expectations of science teachers, were examined by PCK area. As a result of semantic network analysis of Family Resemblance-PCK, it was found that Family Resemblance-PCK expands its boundaries from the existing consensus-PCK, which is the starting point, and new PCK elements were added. Looking at the aspects of Family Resemblance-PCK, [AI-Convergence Knowledge-Contents-Digital], [Community-Network-Human Resources-Relationships], [Technology-Exploration-Virtual Reality-Research], [Self-Directed Learning-Collaboration-Community], etc., form a distinct network cluster, and it is expected that future science teacher expertise will be formed and strengthened around these PCK areas. Based on the research results, changes in the professionalism of science teachers in future schools and countermeasures were proposed as a conclusion.

In this research, a methodology was developed for constructing an appropriate rainfall image database for estimating rainfall intensity based on CCTV video. The database was constructed in the Large-Scale Climate Environment Chamber of the Korea Conformity Laboratories, which can control variables with high irregularity and variability in real environments. 1,728 scenarios were designed under five different experimental conditions. 36 scenarios and a total of 97,200 frames were selected. Rain streaks were extracted using the k-nearest neighbor algorithm by calculating the difference between each image and the background. To prevent overfitting, data with pixel values greater than set threshold, compared to the average pixel value for each image, were selected. The area with maximum pixel variability was determined by shifting with every 10 pixels and set as a representative area (180×180) for the original image. After re-transforming to 120×120 size as an input data for convolutional neural networks model, image augmentation was progressed under unified shooting conditions. 92% of the data showed within the 10% absolute range of PBIAS. It is clear that the final results in this study have the potential to enhance the accuracy and efficacy of existing real-world CCTV systems with transfer learning.

Recently, the platform industry is rapidly growing in the global market, and competition is intensifying at the same time. Therefore, in order for domestic platform companies to have global competitiveness in the platform market, it is necessary to study the platform business ecosystem and success factors. However, most of the recent platform-related studies have been theoretical studies on the characteristics of platform business status analysis, platform economy, and indirect network externalities of platforms. Therefore, this study comprehensively analyzed the success factors of Silicon Valley's business ecosystem proposed in previous studies, and at the same time analyzed the success factors extracted from stakeholders in the actual Silicon Valley platform business ecosystem. And based on these factors, an IPA analysis was conducted as a way to propose a success plan to stakeholders in the platform business ecosystem. As a result of the analysis, among the success factors collected through previous studies, manpower, capital, and challenge culture were identified as factors that are relatively well maintained in both importance and satisfaction in Silicon Valley. In the end, it can be seen that the creation of an environment and culture in which Silicon Valley can use it to challenge itself based on excellent human resources and abundant capital contributes the most to the success of Silicon Valley's platform business. On the other hand, although it is of high importance to Silicon Valley's platform corporate ecosystem, the factors that show relatively low satisfaction among stakeholders are 'learning and benchmarking among active companies' and 'strong ties and cooperation between members', and it is analyzed that interest and effort are needed to strengthen these factors in the future. Finally, the systems and policies necessary for market autonomous competition, 'business support service industry', 'name value', and 'spin-off start-up' were important factors in literature research, but the importance and satisfaction of these factors were lowered due to changes in the times and environment. This study has academic implications in that it comprehensively analyzes the success factors of Silicon Valley's business ecosystem proposed in previous studies, and at the same time analyzes the success factors extracted from stakeholders in the actual Silicon Valley platform business ecosystem. In addition, there is another academic implications that importance and satisfaction were simultaneously examined through IPA analysis based on these various extracted factors. As for academic implications, it is meaningful in that it contributed to the formation of the domestic platform ecosystem by providing the government and companies with concrete information on the success factors of the platform business ecosystem and the theoretical grounds for the growth of domestic platform businesses.
