One of the assimilation policies of Japanese imperialism for the permanent domination in the colonial Joseon is the theory of integration of Japan and Joseon. The theory of integration of Japan and Joseon is a logic that Joseon (Korea) and Japan (Wae) were connected to the same ancestor on the basis of ancient myths. Also it is the assimilation ideology to justify the Colonial rule of those days through the objectification of historical identity or affinity of political and cultural relations of ancient Korean peninsula and Japan (Wae). Japan reorganized our history to meet the colonial point of view, as part of the assimilation policies based on the theory of integration of Japan and Joseon. On the other hand Japan attempted to objectify them through archaeological research and the reinterpretation of the historical remains. The survey, reinterpretation and tourist of the historic sites in historic cities such as Gyeongju and Buyeo were promoted in this context. In particular, the Buyeo, a capital of Baekje, was emphasized upon the close relevance and affinity between Sabi, Baekje and ancient Asuka (飛鳥) in Japan through research and reinterpretation on the Historic Sites. Based on them, Historic Sites Tourism was conducted by reconstructed historic sites toward the colonial Korean. In addition, after the Sino-Japanese war in 1937, Japan tried to realize the politics of space by upgrading and idealizing Buyeo as homeland or Shinto (神都) related to Japanese ancient mythology of the Asuka culture. This paper investigated in what context research, reinterpret and tourist of the historic sites progressed on Buyeo area and how it had soaked through the general public in the Japanese colonial era. First, it is on historic sites. Historic sites research on Buyeo area made an attempt by Sekino Tadashi in 1909 for the first time and the re-excavation of the old burial mounds and temple sites during the Japanese colonial period. Sekino set up a cultural relationship and influences between the ancient China (梁), Korea (百濟) and Japan (倭). Also, he emphasized that Sabi, Baekje largely received influence of Chinese culture and Baekje and Japan Asuka culture had closely relations and affinity. These views had been consistent during the Japanese colonial period. Second, it is the reinterpretation on Historic sites. Buyeo Historic Sites Preservation Society (Buyeo Gojeok Bojonhoe) was established in 1915 and Osaka Kintaro, curator of Baekje exhibition hall redefined the relationship between ancient Japan and Baekje as perspective of the assimilation ideology through the post contextual interpretation. In particular, they emphasized on the close relevance between Baekje's Historic sites and Japan, through the reinterpretation of Nakhwaam, Goransa and Cheongmasanseong. Third, it is the tourist on Historic sites. Buyeo Historic Sites Preservation Society played a leading role in Tourist on Historic sites at the Buyeo region. The main tourist destinations and course were restructured through a reinterpretation on the historic sites. Japan would like to show Buyeo as ideology area, homeland of ancient Japanese culture, toward the Koreans under Japanese colonial era. Thus, research, reinterpretation, and tourism on Historic sites were promoted while they were closely related to each other. The promoting body was Joseon Chongdokbu and pro-Japanese interest group. It's point was 'made' and 'shown' by the eyes of others and a rediscovery of Buyeo as representational space of colony.

There are 35 cultural properties of fourteen kinds in the Demilitarized Zone known so far, but this number is expected to increase in the future. Among them, Cheolwon-Doseong and Jeongol-Chong of Gimhwa should be the first step toward conservation efforts by conducting a joint investigation through the collaboration of North and South Korea. In particular, the joint investigation of Cheolwon-Doseong will not only remind the North and South that they are the same people who have had common history and cultural traditions for a long time, but will also give symbolic meaning to convert the demilitarized zone into a stage for peace. Since Jeongol-Chong is a mass grave of the fallen soldiers of Pyeongan Province who fought against the invasion of the Qing of China, it should be managed as a national designated cultural asset through joint investigation. In addition, the Demilitarized Zone should become a World Heritage Site because of its importance to the legacy of the Korean War, an international war caused by an ideological confrontation. Furthermore, it has more than 6,000 kinds of temperate forests in addition to 100 species of endangered species and natural monuments. The DMZ is very qualified to be a World Natural Heritage Site, and should be included as a World Complex Cultural Heritage Site that qualifies as a World Heritage and World Natural Heritage Site. In the Demilitarized Zone, we can also find numerous highlands, tunnels and posts used during the Korean War, as well as surveillance posts, a military demarcation line, barbed wire fences, and Panmunjom, which were created by the armistice agreement. it would be desirable to select some of its sections and war facilities and to register them as modern cultural heritage assets. Finally, it is necessary to reconstruct the Dorasan Signal Fire Site, which was the communication facility of a traditional era which connected the South (Dorasan) and North (Gaesong). This would symbolize smooth communication between the two Koreas. In order to prepare for the reckless development of the Demilitarized Zone due to the upcoming cease-fire, the government and cultural asset experts will have to work hard to identify and preserve the cultural properties of the Demilitarized Zone, and they will also have to maintain consistent control over matters such as indiscriminate investigation and mine clearance.

The $Sh{\bar{o}}s{\bar{o}}-in$(正倉院) is the detached storage building for Japanese treasures that belongs to $T{\bar{o}}dai-ji$ in Nara, Japan. The reason why $Sh{\bar{o}}s{\bar{o}}-in$ collections are drawing attention is that Japanese artifacts, sculptures, paintings, and other objects that were introduced through the Silk Road, such as Sasanian Persia and India, and those that were introduced from the Unified Silla and Tang China. In addition, hundreds of well-preserved documents of $Sh{\bar{o}}s{\bar{o}}-in$ collections play an important role as a historical reference material covering not only the social situation of the time but also the history of exchange of cultural diplomacy and the change of Buddhist doctrine. In particular, some of collections of $Sh{\bar{o}}s{\bar{o}}-in$ were made in China and may have been imported or received as gifts, but many of the artifacts made in Baekje and Unified Silla are becoming more and more important. This paper examined the research status of $Sh{\bar{o}}s{\bar{o}}-in$ metal crafts of Korean and foreign scholars, and examined the association with the relics of $Sh{\bar{o}}s{\bar{o}}-in$ through metal crafts excavated from the Korean Peninsula. The research on the future direction of $Sh{\bar{o}}s{\bar{o}}-in$ collections should be summarized as follows. 1. Systematization of state-level support and single window for the research of $Sh{\bar{o}}s{\bar{o}}-in$ collections 2. Accurate listing and database of $Sh{\bar{o}}s{\bar{o}}-in$ collections 3. The positive implementation of joint research with Japan and invitation of researchers related to $Sh{\bar{o}}s{\bar{o}}-in$ collections 4. The exchange exhibition between the Korean National Treasures and the $Sh{\bar{o}}s{\bar{o}}-in$ collections 5. Expansion of the research base through the publication and support of books related to $Sh{\bar{o}}s{\bar{o}}-in$ collections.

With the introduction of the system of recognizing masters of craft and performance skills in 1970, the principle of "preserving the original form," which was already in general use, was adopted as a legal principle in the Cultural Heritage Protection Act. While the concept "original form" can be related to tangible elements of heritage through the Act, the intangibility of craft and performance skills does not allow their pinpointing at a particular temporal period or the identification of a particular master from the past as the basis of an original form. Therefore, those craft or performance skills that are available at the point of recognition of relevant masters must serve as the basis of the original form for the intangible heritage concerned. This means that the principle of preserving the original form of intangible heritage has been implemented not based on a fundamental form of materiality, but rather on the craft or performance skills that may be held by a master at the time of his/her recognition as a "temporary original form." This principle has been observed through intangible heritage transmission and education policies for recognized masters and their trainees, contributing to establish an elitist transmission environment in which public were denied to join the education on intangible heritage. Even with policies guided by the principle of preserving the original form, designated craft and performance skills have been transformed contingent upon given social and environmental conditions, thus hindering the preservation of the original form. Despite the intrinsic limitations of the principle of preserving the original form when applied to intangible heritage, this principle has served as a practical guideline for protecting traditional Korean culture from external influences such as modernization and Westernization, and also as an ultimate goal for the safeguarding of intangible heritage, engendering actual policy effects. The Act on the Safeguarding and Promotion of Intangible Cultural Heritage that comes into effect in March 2016 takes the constantly evolving nature of intangible heritage into consideration and resultantly adopts a concept of "essential form" (jeonhyeong) in place of "original form" (wonhyeong). This new concept allows for any transformations that may take place in the environment surrounding the intangible heritage concerned, and is intended to mitigate the rigidity of the concept of "original form." However, it should be noted that "essential form," which is manifested as the unique significance, knowledge, and skills delivered by the intangible heritage concerned, should be maintained according to the guidelines and principles related to heritage conservation. Therefore, the new concept can be understood not as a rupture, but more as a continuum of the concept of "original form."

The Korean Demilitarized Zone (DMZ) was established in 1953 by the Korean War Armistice Agreement. It extends from the estuary of the Imjin River, in the west, to the coast of the East Sea. It is 4 km in width and 148 km in length. However, the ecosystems of the civilian control zone (CCZ) located between the southern border of the DMZ and the civilian control line (CCL) and the CCZ in the estuary of the Han River and the Yellow Sea are similar to those in the DMZ, and, therefore, the ecosystems of the DMZ and the CCZ are collectively known as the "ecosystems of the DMZ and its vicinities." The flora in the DMZ and its vicinities is composed of 1,864 species, which accounts for about 42% of all the vascular plant species on the Korean Peninsula and its affiliated islands. Conducting a detailed survey on the vegetation, flora, and fauna in the DMZ is almost impossible due to the presence of landmines and limitations on the time allowed to be spent in the DMZ. However, to assess the environmental impact of the Munsan-Gaesong railroad reconstruction project, it was possible to undertake a limited vegetation survey within the DMZ in 2001. The vegetation in Jangdan-myeon, in Paju City within the DMZ, was very simple. It was mostly secondary forests dominated by oaks such as Quercus mongolica, Q. acutissima, and Q. variabilis. The other half of the DMZ in Jangdan-myeon was occupied by grassland composed of tall grasses such as Miscanthus sinensis, M. sacchariflorus, and Phragmites japonica. Contrary to the expectation that the DMZ may be covered with pristine mature forests due to more than 60 years of no human interference, the vegetation in the DMZ was composed of simple secondary forests and grasslands formed on former rice paddies and agricultural fields. At present, the only legal protection system planned for the DMZ is the Natural Environment Conservation Act, which ensures that the DMZ would be managed as a nature reserve for only two years following Korean reunification. Therefore, firstly, the DMZ should be designated as a site of domestic legally protected areas such as nature reserve (natural monument), scenic site, national park, etc. In addition, we need to try to designate the DMZ as a UNESCO Biosphere Reserve or as a World Heritage site, or as a Ramsar international wetland for international cooperation. For nomination as a world heritage site, we can emphasize the ecological and landscape value of the wetlands converted from the former rice paddies and the secondary forests maintained by frequent fires initiated by military activities. If the two Koreas unexpectedly reunite without any measures in place for the protection of nature in the DMZ, the conditions prior to the Korean War, such as rice paddies and villages, will return. In order to maintain the current condition of the ecosystems in the DMZ, we have to discuss and prepare for measures including the retention of mines and barbed-wire fences, the construction of roads and railroads in the form of tunnels or bridges, and the maintenance of the current fire regime in the DMZ.

In this study, we divided the portraits in the reign of King Seonjo into those which were created before and after the Japanese invasion. We then examined various aspect of costumes expressed in the portraits of meritorious vassals. To analyze official uniforms (Heuk-Danryeung), we examined the Samo height; the side wings' type and pattern; the Danryeung pattern; the Mu style; the processing method of lateral lines in Danryeung the rank badge and rank belt, the color of Dabho and Cheolrik, which were undergarment of Danryeung and Heuk-wa. The meritorious vassals' portraits, prior to Imran, were analyzed with a portrait of Han Eung-in, a Gwang-kuk Pyeong-nan meritorious vassals. The Samo was the highest of the Choson dynasties, and the cloud and treasure pattern was identified on the side wings. The Heuk-Danryeung was a dark blue(acheongsaeg) Danryeung of manja-shaped cloud patterns with a large outward wrinkled Mu, and it had a wild goose badge (second rank) and a Sabgeumdae. It did not coincide with the Pumgye(Jaheondaebu) recorded in Gugjo-inmulgo. Reddish Dabho for Dangsang-kwan, green Cheolrik which was undergarment of Danryeung, and Heuk-wa. were identified. After the invasion of Japan, portraits of Hoseong, Seonmu, and Cheong-nan meritorious vassals were analyzed through eighteen portraits, including Lee Hyeon-bok. After the invasion of the Japanese, the height of the Samo's top was much lower and the width of the side wings was wider than before the invasion of Japanese. The Heuk-Danryeung was a dark blue (acheongsaeg) Danryeung of manja-shaped cloud patterns with a stretching backward Mu. Rank badge and rank belts were almost identical with the record, but there were two exceptions (Sin-jab and Kim, Sae-sin). Therefore, it was reaffirmed that the meritorious vassals' portraits were drawn by the Pumgye at the time of appointment. Among the undergarments of Heuk-Danryeung, green Dabho(11), blue Dabho(4), reddish Dabho(3), and blue Cheolrik(10), green Cheolrik(6), reddish Cheolrik(1), and yucheongsaeg Cheolrik(1) were identified, However, it is suggested that the Dabho of Hoseong, Seonmu, and Cheong-nan meritorious vassals should be the reddish Dabho of Dangsang-kwan, which is the same as the previous Imran, and a green Cheolrik.

This study was conducted to investigate 106 grassland farms in six provinces including Chungcheongbuk-do, Gangwon-do, Gyeonggi-do, Gyeongsangbuk-do, Gyeongsangnam-do, Jeju-do, and Jeollanam-do to present their problems and causes by surveying the actual state of grassland farms during three years(2014~2016). The grassland survey was divided into three categories; used as the perennial grasses and annual forage crops (Complied with Grassland Act), not used as the perennial grasses and annual forage crops (Not complied with Grassland Act) and failed to meet the farmer and some items are missing or inaccurate (Insufficient contents). Among the surveyed grassland farm, 68 farms (64.2 %) were complied with Grassland Act but 30 farms (28.3 %) were not complied with Grassland Act. Especially, the 8 farms (26.7 %) not complied with Grassland Act used the grassland as other purposes such as tree growing, golf club and swine farm etc.. Therefore, strict on-site investigation by local governments is required to prevent the grassland from being used by illegal purposes. And there's a strong likelihood that 5 farms (62.5 %) avoided the survey violate the positive law. Grassland grades used by the local administrative agencies were not influenced by the factors affecting the yield (existence and non-existence of overseeding and fertilization by grassland grade, soil pH and organic matter content). This results suggest that there is a fundamental problem on the current grassland grade system based on the yield and the irregular time of investigation and lack of on-site investigation are another causes for inaccurate grassland grade. Therefore, the new method evaluating grassland grades which is not based on yield and the thorough on-site investigation by local administrative agencies are necessary when the grassland grade is evaluated.

The first small interfering RNA (siRNA) therapeutics have recently been approved by the Food and Drug Administration in the U.S., and the demand for a new RNA therapeutics bioanalysis method-which is essential for pharmacokinetics, including the absorption, distribution, metabolism, and excretion of siRNA therapeutics-is rapidly increasing. The stem-loop real-time qPCR (RT-qPCR) assay is a useful molecular technique for the identification and quantification of small RNA (e.g., micro RNA and siRNA) and can be applied for the bioanalysis of siRNA therapeutics. When the anti-HPV E6/E7 siRNA therapeutic was used in preclinical trials, the established stem-loop RT-qPCR assay was validated. The limit of detection was sensitive up to 10 fM and the lower limit of quantification up to 100 fM. In fact, the reliability of the established test method was further validated in three intra assays. Here, the correlation coefficient of $R^2$>0.99, the slope of -3.10 ~ -3.40, and the recovery rate within ${\pm}20%$ of the siRNA standard curve confirm its excellent robustness. Finally, the circulation profiles of siRNAs were demonstrated in rat serum, and the pharmacokinetic properties of the anti-HPV E6/E7 siRNA therapeutic were characterized using a stem-loop RT-qPCR assay. Therefore, the stemloop RT-qPCR assay enables accurate, precise, and sensitive siRNA duplex quantification and is suitable for the quantification of small RNA therapeutics using small volumes of biological samples.

Purpose: This study investigated an association between dietary quality and use of convenience foods at convenience stores among high school students. Methods: A total of 474 high school students (225 boys and 249 girls) residing in Incheon participated in this questionnaire survey in June 2018. The subjects were divided into three groups according to the frequency of consumption of convenience foods at convenience stores; less than once a week, 1 ~ 2 times a week, and more than 3 times a week. Dietary quality was assessed using a nutrient quotient for adolescents (NA-Q). Logistic regression was used to investigate an association between dietary quality and use of convenience foods at convenience stores among high school students. Results: For boys and girls, higher monthly allowance was significantly associated with the higher frequency of consumption of convenience foods at convenience stores, whereas school grade, mother's occupational status, family size, extracurricular study, and eating speed were not significantly associated with the frequency of consumption of convenience foods. Higher intake frequency of cookies or sweet and greasy bread, processed beverage, Ramyon, night-time snack, and street food was significantly associated with the higher frequency of consumption of convenience foods for boys or girls. Boys and girls, who had a higher frequency of consumption of convenience foods at convenience stores had significantly greater odds for being in the low grade of dietary quality, especially in the moderation factor. Conclusion: The students who used convenience stores more often appeared to have more monthly allowance and to consume undesirable foods more often. Higher frequency of using convenience foods at convenience stores among high school students was associated with lower dietary quality. These study results can support efforts to provide nutrition education programs and guidelines to students who frequently use convenience foods at convenience stores.

We present the case of long-term observation of a patient with chronic kidney disease (CKD) caused by advanced focal segmental glomerulosclerosis (FSGS) resulting from underlying congenital chloride diarrhea (CLD). A 20-year-old woman was admitted for prolonged proteinuria despite conservative treatment for CLD. She was diagnosed with CLD and started taking KCl salt supplementation from the time of birth. Mild proteinuria was first found at 12 years of age, which progressed to moderate proteinuria at 16 years of age. At 16 years of age, CKD stage 2 with FSGS was diagnosed based on the initial assessment of the glomerular filtration rate (GFR) and kidney histology. On admission, we re-assessed her renal function, histology and genetic analysis. GFR had deteriorated to CKD stage 4 and renal histology revealed an advanced FSGS combined with tubulointerstitial fibrosis. A homozygous mutation in the SLC26A3 gene (c.2063-1G>T) was found by diagnostic exome sequencing and may have been inherited from both parents. CLD patients can be more vulnerable to renal injury, which may also cause progression of renal failure. Therefore, even if there is an early diagnosis and adequate salt supplementation, close monitoring of renal function and tailored treatment should be emphasized for renal protection and favorable CLD prognosis.
