A historical and cultural map needs an overall reflection of the links based on time and space among the various composite factors, instead of requiring a simple collection of the respective relics in a particular region. The study of history, culture and living environment of river system area, a place that is known to as a cradle of civilization, will be able to undertake a role in the research and comparison with other cultural regions, reaching beyond the regional units until now and moreover investigation the international and intercontinental history of civilization. In this context, this research focuses on the establishment of a cultural information system for the public use and the insight to the regional identity and materialization of culture based on Korea's peculiar history and culture. Thus, the information system for Youngsan River area aims to create a form of electronic map that contains various cultural and historical information on river system area, which is a integrated information system based on Web GIS that is open to public use through the internet. The above mentioned system is a combined product from the basic research data on various fields of study, including archaeology, architecture, arts, ecological environment, history, folk customs, literature, and food, while it aims for not only its utilization in interdisciplinary studies but also creating new value as a public database. As a result, the expected effects due to the establishment of historical and cultural information system based on Web GIS of Youngsan River area are as follows: First, the study can contribute to verify a road map of the study on Youngsan River area. Second, it will take a role to stimulate the academical research on the dynamic structure and characteristics of the Youngsan River area. Third, we can also expect an effect of gaining a full foothold in providing an electronic academic source specialized for the study of the historical and cultural map.

The spatial composition of Korean traditional houses is based on the relation of spaces in the background of humanism, society, and composition. According to the analysis of it in this study, we make conclusions as follows; 1) Two compositive axises are formed according to age, sex and status which are the main factors of society and culture in the traditional society. 2) The house of '口-shaped' type in the traditional houses concentrates to the interior. To the exterior, it has the closed and conservative system. The wall in the outside of An-Chae intercepts the sight outward and the extension of space, while the wall in the inside is composed of doors and windows which make the sight and space concentrate to the interior. On the contrary, the doors and windows of Sarang-bang and Nu-maru of Sarang-chae open and extend to the exterior. 3) The spatial composition of the traditional houses is composed of geometrical order system and organic order system.

Our students are shocked by the results that there is an inverse proportion between academic achievement and life satisfaction. Recently, the Organization for Economic Cooperation and Development (OECD) published the PISA 2015 Student Well-Being Report. According to the report, Korean students' education is the highest among OECD countries, but their life satisfaction is the 47th ranked among the 48 OECD and non-OECD countries.[1] This is the cause of the unilateral education using collective achievement in evaluation methods. Therefore, I propose a personalized integrated model utilizing block chain technology. I suggest a personalized education and evaluation system model using selective education and personal approval rather than from teachers' unilateral education. This will no longer open the student's achievement grade system to the public. This change will be accomplished utilizing block chain technology. This technology is characterized by security, transparency and dispersion. The result of this work can be used to improve students' quality of living through a management system of personalized education and evaluation, based on the nature of education.

Microalgal biotechnology has gained prominence because of the ability of microalgae to produce value-added products including biodiesel through photosynthesis. However, carbon and nutrient source is often a limiting factor for microalgal growth leading to higher input costs for sufficient biomass production. Use of municipal wastewater as a low cost alternative to grow microalgae as well as to treat the same has been demonstrated in this study using mini raceway open ponds. Municipal wastewater was collected after primary treatment and microalgae indigenous in the wastewater were encouraged to grow in open raceways under optimum conditions. The mean removal efficiencies of TN, TP, COD-$_{Mn}$, $NH_3$-N after 6 days of retention time was 80.18%, 63.56%, 76.34%, and 96.74% respectively. The 18S rRNA gene analysis of the community revealed the presence of Chlorella vulgaris and Scenedesmus obliquus as the dominant microalgae. In addition, 16S rRNA gene analysis demonstrated that Rhodobacter, Luteimonas, Porphyrobacter, Agrobacterium, and Thauera were present along with the microalgae. From these results, it is concluded that microalgae could be used to effectively treat municipal wastewater without aerobic treatment, which incurs additional energy costs. In addition, municipal wastewater shall also serve as an excellent carbon and nitrogen source for microalgal growth. Moreover, the microalgal biomass shall be utilized for commercial purposes.

Cranial implant removal is recommended if implants become exposed owing to scalp necrosis after cranioplasty. However, it carries the risk of extensive bleeding, and the resultant cranial defects can cause both aesthetic and functional problems. We present a case of a scalp defect exposing a cranial prosthetic implant that was reconstructed with a local flap and salvaged using an indwelling antibiotic irrigation system. A 73-year-old man presented with scalp necrosis after undergoing cranioplasty due to intracranial hemorrhage. The cranial implant was exposed through the scalp defect. Methicillin-resistant Staphylococcus aureus was detected in the culture from the open wound. After debridement of the necrotic tissue and burring of the superficial layer of the implant, a transposition flap was used to cover the defect and an indwelling antibiotic irrigation system was installed. Continuous irrigation with vancomycin was conducted for 5 days, and intravenous vancomycin was continued for 4 weeks. The flap was in good condition at 4 months postoperatively, with no infection. The convex contour of the scalp was well maintained. The patient's neurological status was stable. Exposed cranial implants can be salvaged with continuous antibiotic irrigation as an alternative to implant removal; thus, the risk of bleeding and possible disfigurement may be avoided.

This study examines the spatial structure of Jeju-eupseong (Town-castle) in the Joseon Dynasty. The spatial structure of Jeju-eupseong has distinctive features and regional characteristics that are substantially different from typical eupseong in inland regions. This is mainly attributed to the geographical characteristics of the island and the administrative system with strengthened military functions. Jeju-eupseong displays a distinctive layout of major buildings and road system with a plaza located in its center in comparison with the ones found in inland regions. Gwandeokjeong Plaza in Jeju-eupseong served as the center of Jeju's politics, administration, and culture during the Joseon Dynasty, and it, in the modernization period, has become an open public space in the heart of Old Downtown used for community gatherings. Therefore, this study aims to explore the historical background and distinctive spatial structure of Jeju-eupseong in comparison with eupseong in other parts of Korea. Moreover, the study examines the characteristics of Gwandeokjeong as a plaza that has not been dealt with in other studies of eupseong.

The purpose of this article is to examine whether Myanmar's experience in which dealing with the most exemplary change among rogue states or pariah state in the 21st century is feasible for North Korea's case. Recently, North Korea's willingness to dialogue, reform and open is similar to the precedent in which the Myanmar military junta dismantled its ruling system and turned over transition period through general elections in 2010 and 2015 each. The so-called 'Myanmar Model' refers to a country branded as a rogue state which has been under the international sanctions and pressure, and opening its political system and the market by choosing transformation. However, rapid changes in speed across the entire society after opening up are impossible because the political elite is only the leading role and implementation in the transition. In case of Myanmar, military culture has penetrated into society due to such a long-lasting military dictatorship, and even democratic bloc has become accustomed to authoritarian decision-making process. Furthermore, the "reserved area" of the old regime still exists in a deformed political structure that can not retrieve the interests of the military. Therefore there could not be achieved political development in term of qualification. North Korea also appears unlikely to achieve political and economic assessment in a short period of time, as civil society has not appeared due to its long dictatorship and very low economic development levels. Like Myanmar, North Korea is also likely to control the pace and direction of upcoming reforms and open, as the dictator or most powerful person chose to reform and open up. Therefore, if North Korea moves toward the 'Myanmar Model', there will be high expectations of new changes in the short term, but it could be delayed or stalled in the mid and long term.
