This study was conducted to establish mosquito distribution density and habitat in Sejong city for the prevention of mosquito-borne infectious diseases. The overall distribution of mosquitoes in the Sejong City was investigated, and the population density of mosquitoes in the old and new city was analyzed. Mosquito populations were determined using MOSHOLE and Blacklight traps once a week overnight. We also compared the mosquito population density of the old city and the new city, and the daily mosquito population was calculated using the data from the smart mosquito trap(DMS). Of all the study sites, Geumnam-myeon had the highest number of mosquitoes captured, and the dominant species were Armigeres subalbatus and Culex pipienspallens. Mosquito species with the potential for transmitting diseases were mainly found in Yeonseo-myeon (106 individual), and Geumnam-myeon (101). Mosquito collection rates by MOSHOLE trap and Blacklight trap were 58.49% and 41.51%, respectively. We concluded that using CO₂ would be the most suitable approach for collecting mosquitoes. The mosquito population density in the old city (92.05±7.04) was approximately twice that of the new city(51.50±4.05). Since Sejong City is divided into old city and new city, it is difficult to spot remarkable effects in a standardized way. For effective quarantine, differentiation of quarantine must be established. This study results provide a basis for Sejong City's integrated mosquito control guidelines, and therefore effective control of which we believe will help control the spread of mosquito-borne diseases and reduce damage from mosquitoes.

The reign of King (later Emperor) Gojong of the Joseon dynasty (later the Korean Empire), which lasted from 1863 to 1907, was a period of turmoil caused by political and social instability at home and military incursions by foreign powers. It was also a period in which Joseon was proclaimed as the Korean Empire and, accordingly, the royal seals of the dynasty underwent a major change. Records show that some 135 seals were produced during the reign of Gojong. The present study of the makers and styles of the royal seals aims to reveal a wealth of information on the seals, which typically had handles in the shape of either a turtle or dragon. Among the seal makers of this era, Jeon Heung-gil was particularly highly regarded as a Golden Royal Seal Artisan (Geumbojang) because he was highly skilled at making both turtle and dragon handles. Kim Eun-seok, a master Jade Royal Seal Artisan (Okbojang), also excelled in the production of turtle and dragon handles for his jade seals. Another master Jade Royal Seal Artisan, Yi Jung-ryeo, is noteworthy because he developed a new style of jade royal seals, which eventually became the dominant style after 1890, when Kim Eun-seok was not active. Furthermore, after the 1890s, his style was also applied to the production of the gold royal seals and developed as the dominant style. Regarding the dragon handles adopted after the proclamation of the Korean Empire, both the golden and the jade royal seals were made in the same style by the same artisans in the service of the Joseon dynasty. They adopted the style of Chinese imperial seals when they began making seals with dragon handles for the Korean Empire, although the basic shapes of both handle and dragon were copied from those made during the Joseon period. As a ceremonial object symbolizing the authority and legitimacy of the royal or imperial family, the style of the royal seals was influenced mainly by changes in the political situation at home and abroad. As Gojong's reign was a period in which more royal seals were made than in the reign of any other ruler, the seals originating from his reign constitute a richer source of information about the efforts of the dynasty to preserve the tradition while effectively dealing with the changes of the new era.

The effect of Fe and BO₃ doping on structure, thermal, and electrical properties of Li_1+xFe_xTi_2-x(PO₄)_3-y(BO₃)_y (x = 0.2, 0.5)-based glass and glass ceramics was investigated. In addition, their crystallization behavior during sintering and ionic conductivity were also investigated in terms of sintering temperature. FT-IR and XPS results indicated that Fe²⁺ and Fe³⁺ ions in Li_1+xFe_xTi_2-x(PO₄)_3-y(BO₃)_y glass worked as a network modifier (FeO₆ octahedra) and also as a network former (FeO₄ tetrahedra). In the case of the glass with low substitution of BO₃, boron formed (PB)O₄ network structure, while boron preferred BO₃ triangles or B₃O₃ boroxol rings with increasing the BO₃ content owing to boic oxide anomaly, which can result in an increased non-bridging oxygen. The glass transition temperature (GTT) and crystallization temperature (CT) was lowered as the BO₃ substitution was increased, while Fe²⁺ lowered the GTT and raised the CT. The ionic conductivity of Li_1+xFe_xTi_2-x(PO₄)_3-y(BO₃)_y glass ceramics were 8.85×10^-4 and 1.38×10^-4S/cm for x = 0.2 and 0.5, respectively. The oxidation state of doped Fe and boric oxide anomaly were due to the enhanced lithium ion conductivity of glass ceramics.

Cheongpunggye is located in a valley where Baekaksan, the main mountain of Seoul and Inwang Mountain corresponding to right-white tiger(石白虎) divination based on topography are crossed. The owner of Cheongpunggye is Seonwon Kim Sangyong and many people had visited there without pause because of beautiful landscape since the early times of Chosun. Seonwon Kim Sangyong had ever studied together with Yulgok Yi I and Woogye Seong Hon. He was one of the Western faction(Seo-in) which was the leading power of Injo Coup and died for his chastity during Second Manchu Invasion of Chosun. He is known as a model of fidelity which is a symbol for scholar's spirit in Chosun together with his younger brother Cheongeum Kim Sangheon. Jangdong region, the clan village of New Andong family was the birthplace of Yulgok School which was the fundamental of scholar spirit of Chosun. And Jangdong would be the source of Jin-Gyeong(Real Scenery) Culture which was bloomed by Baekak club composed of Gyeomjae Jeong Seon, Sacheon Lee Byeongyeon, and Gwanajae Cho Yeongseok. The contents of this study are as follows. First, this study explored the placeness of Seochon region through the historical background like the relation between Jangdong, the clan village of Andong Kim family and Andong Kim family, and achievements of Seonwon Kim Sangyong and circumstances of that times. Second, this study tried to know original landscape of Cheongpunggye by investigating location, topography, water system etc. based on analysis of literature, old map, and paintings describing Cheongpunggye. The study was progressed in this way. To infer the original landscape, about 50 landscape elements of Cheongpunggye shown in Punggyejibseunggi(楓溪集勝記), Cheongpunggye Cheop, Cheongpunggye(淸風溪), the work of Gyeomjae Jeong Sean were searched, and then the location and form of the elements was analyzed. Furthermore, by analyzing the meanings of the names for the landscape elements, the thoughts(Naturalism, Taoism, Confucianism, Buddhism) supporting the structure of Cheongpunggye could be inferred. It is thought that these findings can contribute to exploration of placeness of Cheongpunggye. The study on original landscape of Cheongpunggye can be used as basic data when these works are executed-revival of Cheongpunggye, restoration of small streams in upper part of Cheonggyecheon, renewal of Seochon region.

This study was conducted through the typological analysis of theatrical activities and playscript of Packaging Troupe, which was a wandering theater troupe. It seems the activities of the packaging troupe were very active about in the 1950s. They approached to the public with various repertoires and gained popularity during the process. The playscript used in their plays can be divided into several types such as Yi dynasty drama, historical drama and modern drama and their titles are almost same as or similar to those used in Changgeuk troupe (classical opera), Female Gukgeuk troupe (Female classical opera), or Female Nongak troupe (Female farm musical band). Also, as themes, subject matters, and characters were partially same, the characteristics of previous theatrical activities could be reviewed through the playscript of packaging troupe. Also, the characteristics of the playscript of packaging troupe can be found in the list of gramophone record. The changes in popular culture can be examined in the flow of plays with various forms such as theater, film, and gramophone through the comparison between the characteristics of playscript types of packaging troupe around in the 1950s and the list of gramophone record. A typological analysis of playscript of packaging troupe confirmed the activities of packaging troupe lasted around in the 1950s. Also it can be inferred from Hyeopryulsa, Changgeuk troupe, Female Gukgeuk troupe, or Female Nongak troupe, which used traditional subject matters as repertoire of performance. Those were possible because repertoires were composed and contents changed according to the needs of the public. The changes can be also confirmed through the list inserted in the gramophone record. The association can be inferred through the same title as that of the playscript of packaging troupe and similarity of performance curtains and subject matters. As such, the interest and flow of popular culture can be examined through the types of playscript of theatrical activities of packaging troupe.

EIU has evolved diversely depending on the national environment and culture on the basis of the philosophy of individual human rights and world peace articulated in the "1974 Recommendation on EIU". However, the global environment surrounding EIU has been changed socially, economically, culturally and ecologically in the 21st century, and therefore it is necessary to raise the following questions: Is the concept of EIU initiated for international understanding and cooperation for world peace in the 20th century still valid in the 21st century? Which direction should we take in order for EIU to be efficient in the globalized world? To answer these questions, this study reviewed and analyzed the historical development and current trends of the EIU in the regions of Europe, North America, Asia Pacific area, and Africa. For the empirical study, thirty-four experts in EIU selected from the four regions were interviewed by the researchers. Based on the interviews and the related literature review, it was found that the diverse terms of EIU were used in the four regions and the focus on EIU was different depending on the geographical, historical and social environment of each region. But, despite of the diversity in terminology in EIU, human rights, peace, equity and social justice which are emphasized by UNESCO, were universally taught in EIU. The EIU in these regions is currently dealt with in school education, social education and lifelong education, and particularly global citizenship allowing multiple identities is importantly treated together with citizenship education. Another important aspect of EIU that was commonly found in these four regions was that global citizenship education for solving global problems was coexistent with the reinforcement of nationalism for the economic competency of each nation in a globalized world. The issue of global inequality was particularly dealt with in EIU, and the teaching of voluntary civic involvement and responsibility were particularly emphasized in EIU. Based on these research findings, the study proposes "glocalism", connecting global issues with local issues for solving global problems, as a new approach to the EIU of the 21st century.

This paper is aimed at analyzing the characteristics of Image-Meaning theory focused on image in the early days of the Joseon Dynasty and SongMing period. Zhouyi' theory in the early days of the Joseon Dynasty was constructed on the basis of Zhouyi' theory of SongMing period. The characteristics of Image-Meaning theory in the early days of the Joseon Dynasty can be explained largely by two routes. One is the perspective of critical succession on Zhouyi'theory of focusing on meaning that led Chengyi(程?) and Yangwanli(楊萬裏). As the representative of this route, Gwongeun and Toegye not only asserted Image-meaning theory focused on meaning, but also developed a perspective of taking all the image and meaning. The other is the active succession and creative transformation about Image-Meaning theory of Tushuxue that led Chentuan(陳?) and Shaoyong(邵雍). As the representative of that route, Yulgok and Yeohun explained the schematic diagram of the universe of the universe by using methodology of Tushuxue. Furthermore, they actively succeed Shaoyong' Zhouyi theory to expand Image-Meaning theory focused on number. In addition, Cho, Haoyi(曺好益)described the propositions - "meaning is not out of image area, image equipped with meaning all, then there is no law of limitation in image adopted theory. Those propositions are opposed to Chengyi(程?) and Zhuxi(朱熹)' ZhouYi' theory.

This is a cross-sectional study that suggests ways to activate forest welfare services (FWS) by investigating the infrastructure, service status, and perception on FWS in Korea. In August 2016, a structured email survey was conducted in nation widely. The respondents were mostly directors and general secretary (75.0%). The considerable number (16.3%) of nursing homes (NH) use some floors of the complex buildings that would be difficult to have FWS infrastructure and about 30% of those without forests near the facilities. The directors of NH recognize that FWS has positive effects on the elderly. However, FWS is not an requisite of the longterm care insurance benefit, and so costly and effort-intensive that FWS has not been activated so far. In order to activate FWS in NHs, it is necessary to develop and disseminate the guidelines on FWS that anyone can easily followed. In addition, when the National Health Insurance Corporation evaluates NHs, they should evaluate not only whether there is a wandering or walking space, but also whether it has forest healing factors such as forests. It is also necessary to create a barrier-free environment both inside and outside of NHs, increasing accessibility to the toilet in gardens, paving a passage for wheelchairs and lifts in forests near NHs. Through these efforts, it is expected that FWS will be activated to provide physical, mental rest and comfort, appropriate cognitive stimulation to the NH residents at the end of life.
