Darangyi paddy in Namhae Gachon village provides natural beauty with its distinct location. Darangyi is a traditional Korean landscape, shaping a circular form to serve continuous cultivation. Despite the paddy's landscape, it is difficult to preserve its natural scenery due to many factors such as inadequate visual analysis. Under the belief that there is a necessity to preserve Darangyi paddy, the research in visual features of the paddy began to illustrate the relevance between its viewpoint and landscape objects. First, we researched typical view structures. When considering the visual features, Darangyi paddy landscape objects has a viewpoint from the horizontality to its below, which its center area is about $-5^{\circ}{\sim}-30^{\circ}$. From the analyzed data, the scenary of Darangyi paddy, which most people agree its decency, is formed in a visually decent location. The above type of measure of visual structure in Darangyi paddy is expected to be applied in maintenance of foothold of views in the future. Second, the surrounding elements play important parts to form the whole landscape of Gachon Darangyi paddy. Although Darangyi paddy is the principal part of the scenary, the landscape analysis showed a high relevance with the paddy's identity, forest around the paddy, sky, ocean, settlements, and the roads in terms of visual perception. It was affirmed that those elements around the paddy play important parts in structuring and providing the beauty of the whole landscape. Various viewy objects are seen obvious especially in a long distance, and the splendid scenary proved that those viewy objects are in indispensable location. In order to preserve the paddy, it seems necessary to consider the surrounding envrionment of Darangyi paddy, not just the paddy's sole landscape form. Third, Darangyi paddy has a distinct seasonal characteristics. According to the survey analysis, the full heading time in spring and time when people can take a picture against the sun light proved magnificence of Darangyi paddy. Thus, it would be ideal to maintain Darangyi paddy by securing the sunlight condition with decent landscape view and the views from its surrounding environments or researching the ways to principally maintain the surrounding environments.

This study focused on relevant rock names related to Sinsun(神仙) which had been settled as Taoist traces were combined with places. While interpreting major features of Sundoism relevant rocks, it also discussed types and places of rocks reflected in their names by considering distinct characteristics of landscape characters that ancestors viewed through the rocks or on the rocks. Conclusion of this study is summarized as follows. 1. Among the rock names related to Sinsun, the most frequently discovered one was Sinsunbawi(52) and followed by Sinsunbong(神仙峰: 38), Sinsundae(神仙臺: 31). Other than these, there were Gangsundae(降仙臺: 12), Sunyoodae (仙遊臺: 10) and Sasundae(四仙臺: 5). 2. In the name of Sinsundae, 'Dae(臺)' ascertains that it was located in greatly superb place in the aspects of viewpoint and appreciation where landscape superiority and overlook scenery were fair and outstanding. 3. Sinsunbong was named for a peak of mountain. At the same time, it implied a notion of worship with images of 'merging with sky' or 'looking up.' Most of time, Sinsunbong indicated the tallest rock in the mountain chain. 4. A significant number of Sinsunbong had names where legends of Sinsun's Go game or descent were originated from. It shows that 'Sinsun(仙) and Go game' used to be very important motives for folk etymology of Sinsun related rocks. Along with the Sinsundae, a number of Sinsunbawi were also turned out to exist in land and ocean with excellent marine view. 5. According to analysis of their altitudes and heights of the peaks where the rocks belong to, Sinsunbong, Sinsundae and Sinsunbawi were in order. It might indicate that the rocks were located on top of mountain or that Sinsunbong represented the mountain itself. Compared to this, Sinsundae was located in where distant panoramic views were overlooked. It was not necessarily to be in peak but in where with a great view like Taoist world. On the other hand, Sinsunbawi was located in where has fine scenery and great valley not so far from villages, which proved its name had been influenced by place feature not altitude. 6. Feature of rock with Sinsun related name is to comprise visual stability of worship object with close linkage to attitude of worshiper. Considering its deep connection with communicative method of worship object and worshiper, seemingly it was main factor to lead folk etymology of rocks with Sinsun related names. 7. Rock is an object with the greatest implication of Sinsun imagination and Sinsun rocks show most clearly the fact that Taoism, which used to be considered as inaccessible, had been actualized in a visual and realistic manner with the change of time.

This research has studied the building awareness of Nu-Jeong that a view of nature and aesthetic consciousness to unite the nature are inherent by considering Nu-Jeong of scholars who left fame and wealth behind and retired to hermitage in the backwoods in the 16~18 Century. This is to clarify correlation with leaving nature as it is, namely, an ideal state that scholars at the time would enjoy, through landscape awareness accepted into Nu-Jeong literature. In addition, this research has tracked the ideologic flow that acts on space formation by clarifying Korean unique meanings inherent to Nu-Jeong's cultural landscape. As a suggestion for this, the interpretation through 'Pungsu location Nu-Jeong name's analysis Nu-Jeong literature analysis', etc. was tried, so its integrated conclusion is as follows. It is not a chance that scholars of Joseon have left numerous literature works singing the nature. They already had huge interest and knowledge on the nature, and achieved active poetic exchange by sublimating the praise of nature as literature. Nu-Jeong, which was a place of exchange like this, had cleanliness of the nature and ideological purity as an oppositional space on turbid political realities. The Nu-Jeong literature drew the nature into a literature space as it is, without doing abstraction or ideation on the nature. The owner of Nu-Jeong exclusively possessed such natural landscape in grim and independent postures, so it provided a clue of Nu-Jeong cultural landscape that this research aimed to discuss. Scholars who aimed to raise wide and large vigor filled in between the sky and earth got to convince that people are born from the nature, grow in the nature and finally return to the nature. What people are born from the nature and finally return to the nature is just consistent with Taoistic and Zhua-ngzi thoughts denying human work, and leaving nature as it is or nature itself remained intact which is an ideal state. The construction at the time is a vessel containing the spirit of the times of the era. This thesis has proved that the Nu-Jeong culture of scholars located on the central line of Korean landscape was the flower of Joseon's scholar culture by interpreting it semantically.

Microclimatic data were measured, and the human thermal sensation was analyzed at 10 local climate zones based on the major land cover classification to investigate the thermal environment of urban areas during summer nighttime. From the results, the green infrastructure areas (GNIAs) showed an average air temperature of 1.6℃ and up to 2.4℃ lower air temperature than the gray infrastructure areas (GYIAs), and the GNIAs showed an average relative humidity of 9.0% and up to 15.0% higher relative humidity. The wind speed of the GNIAs and GYIAs had minimal difference and showed no significance at all locations, except for the forest location, which had the lowest wind speed owing to the influence of trees. The local winds and the surface roughness, which was determined based on the heights of buildings and trees, appeared to be the main factors that influenced wind speed. At the mean radiant temperature, the forest location showed the maximum value, owing to the influence of trees. Except at the forest location, the GNIAs showed an average decrease of 5.5℃ compared to GYIAs. The main factor that influenced the mean radiant temperature was the sky view factor. In the analysis of the human thermal sensation, the GNIAs showed a "neutral" thermal perception level that was neither hot nor cold, and the GYIAs showed a "slightly warm" level, which was a level higher than those of the GNIAs. The GNIAs showed a 3.2℃ decrease compared to the GYIAs, except at the highest forest location, which indicated a half-level improvement in the human thermal environment.

This study aimed to identify the landscape perception and landscape characteristics of users by utilizing SNS data generated by their experiences. Therefore, how to recognize the main places and scenery appearing on the island, and what are the characteristics of the main scenery were analyzed using online text data and photo data. Text data are text mining and network structural analysis, while photographic data are landscape identification models and color analysis. As a result of the study, First, as a result of frequency analysis of Bakji·Banwol-do topics, we were able to derive keywords for local landscapes such as 'Purple Bridge', 'Doori Village', and location, behavior, and landscape images by analyzing them simultaneously. Second, the network structure analysis showed that the connection between key and undrawn keywords could be more specifically analyzed, indicating that creating landscapes using colors is affecting regional activation. Third, after analyzing the landscape identification model, it was found that artificial elements would be excluded to create preferred landscapes using the main targets of "Purple Bridge" and "Doori Village", and that it would be effective to set a view point of the sea and sky. Fourth, Bakji·Banwol-do were the first islands to be created under the theme of color, and the colors used in artificial facilities were similar to the surrounding environment, and were harmonized with contrasting lighting and saturation values. This study used online data uploaded directly by visitors in the landscape field to identify users' perceptions and objects of the landscape. Furthermore, the use of both text and photographic data to identify landscape recognition and characteristics is significant in that they can specifically identify which landscape and resources they prefer and perceive. In addition, the use of quantitative big data analysis and qualitative landscape identification models in identifying visitors' perceptions of local landscapes will help them understand the landscape more specifically through discussions based on results.

The extragalactic background suggests half the energy generated by stars was reprocessed into the infrared (IR) by dust. At z~1.3, 90% of star formation is obscured by dust. To fully understand the cosmic star formation history, it is critical to investigate infrared emission. AKARI has made deep mid-IR observation using its continuous 9-band filters in the NEP field ($5.4deg^2$), using ~10% of the entire pointed observations available throughout its lifetime. However, there remain 11,000 AKARI infrared sources undetected with the previous CFHT/Megacam imaging (r ~25.9ABmag). Redshift and IR luminosity of these sources are unknown. These sources may contribute significantly to the cosmic star-formation rate density (CSFRD). For example, if they all lie at 1< z <2, the CSFRD will be twice as high at the epoch. We are carrying out deep imaging of the NEP field in 5 broad bands (g, r, i, z, and y) using Hyper Suprime-Camera (HSC), which has 1.5 deg field of view in diameter on Subaru 8m telescope. This will provide photometric redshift information, and thereby IR luminosity for the previously-undetected 11,000 faint AKARI IR sources. Combined with AKARI's mid-IR AGN/SF diagnosis, and accurate midIR luminosity measurement, this will allow a complete census of cosmic star-formation/AGN accretion history obscured by dust.

Considering the development of aerospace, military science and technology since the 20th century, the sky is very important for the nation's existence and prosperity. The proverb "Whosoever commands the space commands the world itself!" emphasizes the need for the command of the air. This essay is the first study on the status of airspace after reunification. First, the territorial airspace is over the territory and territorial sea, and its horizontal extent is determined by the territorial boundary lines. Acceptance of the present order is most reasonable, rather than attempting to reconfigure through historical truths about border issues, and it could be supported by neighboring countries in the reunification period. For peace in Northeast Asia, the reunified Korea needs to respect the existing border agreement between North Korea and China or Russia. However, the North Korean straight baselines established in the East Sea and the Yellow Sea should be discarded because they are not available under United Nations Convention on the Law of the Sea. It is desirable for the reunified Korea to redefine the straight baselines that comply with international law and determine the territorial waters up to and including the 12-nautical mile outside it. Second, the Flight Information Region (hereinafter "FIR") is a region defined by the International Civil Aviation Organization (hereinafter "ICAO") in order to provide information necessary for the safe and efficient flight of aircraft and the search and rescue of aircraft. At present, Korea is divided into Incheon FIR which is under the jurisdiction of South Korea and Pyongyang FIR which is under the jurisdiction of North Korea. If North Korea can not temporarily exercise control of Pyongyang FIR due to a sudden change of circumstances, it is desirable for South Korea to exercise control of Pyongyang FIR, and if it is unavoidable, ICAO should temporarily exercise it. In reunified Korea, it is desirable to abolish Pyongyang FIR and integrate it into Incheon FIR with the approval of ICAO, considering systematic management and control of FIR, establishment of route, and efficiency of management. Third, the Air Defense Identification Zone (hereinafter "ADIZ") is a zone that requires easy identification, positioning, and control of aircraft for national security purposes, and is set up unilaterally by the country concerned. The US unilaterally established the Korea Air Defense Identification Area (KADIZ) by the Declaration of Commitment on March 22, 1951. The Ministry of Defense proclaimed a new KADIZ which extended to the area including IEODO on December 13, 2013. At present, North Korea's military warning zone is set only at maritime boundaries such as the East Sea and the Yellow Sea. But in view of its lack of function as ADIZ in relations with China and Russia, the reunified Korea has no obligation to succeed it. Since the depth of the Korean peninsula is short, it is necessary to set ADIZ boundary on the outskirts of the territorial airspace to achieve the original purpose of ADIZ. Therefore, KADIZ of the reunified Korea should be newly established by the boundary line that coincides with the Incheon FIR of the reunified Korea. However, if there is no buffer zone overlapping with or adjacent to the ADIZs of neighboring countries, military tensions may rise. Therefore, through bilateral negotiations for peace in Northeast Asia, a buffer zone is established between adjacent ADIZs.
