The World Heritage Subcommittee of the Cultural Heritage Administration which examine The World Heritage Subcommittee of the Cultural Heritage Administration which The World Heri The World Heritage Subcommittee of the Cultural Heritage Administration which examined the Placenta Chamber of King Sejong's Princes applied for the world heritage priority list in 2020 recommended expanding it to the royal placenta chambers of Joseon distributed nationwide for successive registration instead of registering the Seongju placenta chamber only. On account of that, the issue of selecting items has become one of the important topics to be discussed in the registration of world heritages. Accordingly, this researcher investigated the subjects of successive registration based on such conditions as excellent universal value, heritage protection and management, authenticity, and completeness among the real estate cultural properties demanded by the UNESCO World Heritage Committee. First, 22 placenta chambers, the real estate cultural properties designated as cultural properties and protected and managed by the state and local governments, are subject to it. Second, it seems that placenta chambers that can be restored through research and historical investigation and become designated as cultural properties can additionally be added. Third, items such as the Seosamneung Royal Tombs built by Lee Wang-jik in the Japanese colonial era or Seongjong Placenta Chamber relocated as an example to realize the completeness of Joseon's Royal Placenta Chambers can be included as well. Meanwhile, many of the items designated as cultural properties are not in the original location, and they can be divided into those that were relocated for the intentions of the Japanese Empire and those that were not. Therefore, the researcher insists that it is necessary to select and add items with which we can understand the historicity in the relocation of placenta chambers during the Japanese colonial era and also to quickly designate those that have not been designated as cultural properties yet. Therefore, regardless of designation as cultural heritage, local governments must promote both restoration and designation and strive to include them in the list of successive registration of world heritages grounded on thorough historical investigation. Moreover, to add them to the list of successive registration of world heritages, the Cultural Heritage Administration and local governments should promote continuous research and genuine restoration of individual placenta chambers.

The continuous glass fiber reinforced poly-lactic acid (PLA) composite was manufactured by direct melt impregnation. The mechanical and thermal properties of continuous glass fiber reinforced PLA composite were observed. Measured properties were compared with the reference values of neat PLA and the injection molded glass fiber/ PLA composite. The continuous glass fiber reinforced PLA composite having a fiber volume fraction of 27.7% shows enhanced tensile strength of 331.1 MPa, flexural strength of 528.6 MPa, and flexural modulus of 24.0 GPa. The enhanced heat deflection temperature (HDT) and the increased cystallinity were also observed. The degree of impregnation as a function of pulling speed was also assessed. The degree of impregnation at the pulling speed of 5 m/min was over 90% in this research.

This study was conducted to analyze the potential of Baekdu-daegan Mountain System (BDMS) in the Republic of Korea for World Heritage inscription and undertook preliminary global comparative analysis. UNEP WCMC global datasets, World Heritage global gap analyses and thematic studies conducted by IUCN were reviewed to see if the BDMS could have been identified within these as a priority area for World Heritage. With respect to potential Outstanding Universal Value this study found that the case for BDMS was weak. The BDMS lies within biogeographic regions which are already represented on the World Heritage List and at a global scale its natural values do not stand out. It was emphasized that a more fine scale analysis of the values should be undertaken. The BDMS stands out at a global scale in terms of the degree of contiguity between protected areas along its length and the legal and institutional frameworks established in the Republic of Korea. The BDMS has potential for a trans-national and serial properties along the full length of the BDMS, if two Koreas agree to work together.

In this study, we fabricated jute fiber reinforced polylactic acid (PLA) composite in the form of sandwich panel structure which includes core foam of chopped jute fiber reinforced PLA and outer skin layer of continuous glass fiber reinforced PLA. Flexural properties of the composite were assessed for different jute fiber weight fractions. Density of the core foam ranged from 0.31 to 0.67 $g/cm^3$ and void content fraction 0.51 to 0.71. The maximum flexural strength was 92.7 MPa at 12.5 wt.% of jute fiber content, and the maximum flexural modulus was 7.58 GPa at 30.0 wt.%. Cost analysis was also conducted. The cost to enhance the flexural strength of the applied structure was estimated to be $0.010USD/m^3/MPa$ for 12.5 wt.% fiber content.

Nuruk is a starter culture of Korea manufactured by spontaneous fermentation of grains. We isolated bacteria of the genera Bacillus and Staphylococcus, and lactic acid bacteria (LAB) from eight commercial nuruk samples collected from four districts of Korea using selective agar media and identified them based current taxonomic standards. Bacillus was detected in all samples, but Staphylococcus or LAB were not detected in three samples. In seven samples, except one sample scored the highest cell number of LAB, Bacillus and Staphylococcus were counted as the highest and the lowest numbers, respectively. Six species of Bacillus were identified, and B. subtilis, B. velezensis, and B. licheniformis were predominant species. Nine species of coagulase-negative Staphylococcus were identified, and the predominance of S. pseudoxylosus and S. saprophyticus was confirmed. Ten species of LAB including Enterococcus, Lactobacillus and close relatives, Pediococcus, and Weissella were identified. P. pentosaceus was identified as the predominant species.

반복적인 실험을 통해 부추 김치에서 분리된 대부분의 유산균은 항유전독성 효과를 갖는 것으로 보인다. 이는 전에 시행되었던 각종 김치의 유산균을 이용한 항유전독성 효과 조사에서도 다른 김치유산균에 비해서 부추김치의 유산균이 항유전독성효과가 높다는 것을 통해서도 증명되었다. 유산균 섭취시에 균주가 장내의 혐기성 상태에서 존재하게 되는데 아직까지는 혐기성 상태에서 배양된 균주의 항유전독성효과가 그다지 높지 않은 것으로 보여진다. 따라서 혐기성 상태에서 배양된 항유전독성효과가 높은 균주를 찾는 것이 시급하다고 본다. 그러나 호기성 상태에서 배양된 항유전독성이 높은 균주들이 혐기성 상태에서도 배양되는 것을 확인하였고 이 균주들의 장내 생존 가능성을 예측할 수 있다. 물론 이를 뒷받침하기 위해서 이 유산균들이 위와 장내의 조건에서 생존가능하는지에 대해 pH 생존 조사를 해야 할 것이다. 또한 혐기성 상태에서 배양되었을 때에도 이 균주들이 항유전독성 효과가 있는지도 앞으로 실시되어야 할 과제일 것이다. 항유전독성 효과와 달리 항암효과에 대해서는 높은 효과를 보이지 않았지만 본래 CT-26 세포가 대장암 세포이기에 이 세포 자체의 DNA에 손상 복구율을 부여했다는 것에 의미를 둘 수 있겠다. 항유전독성효과와 항암효과가 있는 유산균의 분리를 통해 우리가 다음으로 해야 될 일은 첫째로 이 균주들에 대해 여러 가지 특성을 찾아 동정하고 둘째로 지금까지 밝혀진 결과를 in vivo상에서 검증하는 것이다. 지금까지 밝혀진 유산균은 대부분 발효 유제품에서 자라는 유산균인데 한국인이 주로 섭취하는 각종 김치나 부추김치 등에서 분리한 균주에서도 이 기능이 있음을 밝힌다면 이들의 소비에 도움이 될 것이고 또한 이 균주들을 이용해 향유전독성, 항암성 등이 있는 기능성 제품을 만들어 낼 수 있을 것이다.첨가한 햄보다 적었다.분산시키는 것으로 나타났다. 또한 고기를 단계별 복합처리로 저 allergy 처리는 단계별로 점차적으로 allergy가 감소되었다. 즉 단계별로 억제가 안되는 것부터 억제되는 처리를 복합적으로 처리한 것으로 그 단계는 천연효소처리에 인산염 처리, 여기에 초음파 처리, 마지막 단계로 3분 끓이면 억제율이 68%까지 억제되었다. 이는 단일처리시 전혀 억제를 못하는 처리를 단계별로 한 단계씩 더해가면 allergy 억제효과가 나타난다고 할 수 있겠다. 초음파 처리도 역시 저 allergy 처리 공정에 이용될 수 있는데 이것은 그 처리로 인해 새로운 알러젠이 생성될 수도 있다. 또한 복합처리로 allergy를 감소시키면 연속적이고 동시적으로 하기 때문에 원가를 절감할 수 있다.환경현안에 대한 정치경제적 접근을 외면하지 말고 교과서 저작의 소재로 삼을 수 있어야 하며, 이는 '환경관리주의'와 '녹색소비'에 머물러 있는 '환경 지식교육'과 실천을 한단계 진전시키는 작업으로 이어질 것이다. 이후 10년의 환경교육은 바로 '생태적 합리성'과 '환경정의'라는 두 '화두'에 터하여 세워져야 한다.배액에서 약해를 보였으나, 25% 야자지방산의 경우 50 ${\sim}$ 100배액 어디에서도 액해를 보이지 않았다. 별도로 적용한 시험에서, 토마토의 경우에도 25% 야자지방산 비누 50 ${\sim}$ 100배액 모두 약해를 발생하지 않았으나, 오이에서는 25% 야자지방산 비누 100배액에도 약해를 나타내었다. 12. 이상의 결과, 천연지방산을 이용하여 유기농업에 허용되는 각종의 살충비누를 제조할 수 있었으며, 방제가 조사결과 진딧물, 응애 등 껍질이 연약한 곤충의 방제에 효과적인 것으로 나타났다. 따라서 제조된 살충비누를 활용하면 환경친화적인 해

In March 2015, The Agency for Cultural Affairs of Japan implemented a project called "Japan Heritage," which aims to promote the unique narratives of cultural properties of the region by branding the locality for revitalization in preparation for the 2020 Tokyo Olympics and Paralympics. This bottom-up approach of cultural policy has been called a "Cool Japan Strategy of Cultural Heritage" in the 21st century, which effectively incorporates local cultural heritage and tourism. However, although a total of 67 Japan Heritage projects have been designated as of December 2018, almost none has been introduced in the academic forum in Korea. On the basis of this background and a lack of academic awareness in Korea on Japan's recent cultural policies, this research aims to focus on the three cases of Gunma Prefecture implemented in local, global, and glocal aspects. To specify, the cases are the "Gunma Silk Heritage" project, implemented in 2011, the "Tomioka Silk Mill and Related Sites" project that was included on the UNESCO World Heritage List in 2014, and "The Best Wife in the World - Silk Story of Gunma," case certified as the first project of "Japan Heritage" launched in 2015. Based on the questionnaire method conducted with the World Heritage Registration Promotion Division in Gunma Prefectural Government, as well as a literature view, the research revealed that the consecutive implementation of a series of cultural heritage projects in Gunma is not coincidental, but rather a strategy aiming to create a synergism where each project complements the others. Moreover, this paper demonstrates that Gunma Prefecture has been utilizing the local silk industry as a tangible and intangible cultural resource in multi-layered heritage projects, resulting in a "spiral synergy effect" and a "chain of the recognition process." In conclusion, it illustrates the recent trend of utilizing cultural heritage in the context of the Cool Japan strategy, which seeks to move away from the administration of maintaining the status quo cultural heritage protection to a proactive one with greater potential growth. This research may thus provide meaningful insight into the utilization of domestic historical and cultural resources as well as related policy-making, in that it will ultimately promote the chain effect of linking the multiple heritage policies and projects at the local, global, and glocal levels.

본 연구는 1997년 세계문화유산으로 지정된 수원화성의 야간경관조명연출에 따른 조명실태와 효과를 조사 분석하였다. 평가대상은 화성의 경관조명시설이 설치된 33개소 중 측정당시 설치가 완료된 성곽의 내 외부와 서북공심돈을 선정하였다. 평가방법은 야간에 조명현황조사 및 물리량의 측정을 실시하였다. 물리량은 피조면의 휘도, 색온도 및 색도를 측정하였으며, 이를 토대로 경관조명의 연출효과를 분석하였다. 분석결과, 전체적인 조명방식은 건축물 하단부에 설치된 지주등으로 상향조명을 하거나, 외곽 투광기를 이용한 전반조명이 병용되고 있었다. 조명연출실태는 성벽의 경우 연속된 성곽의 이미지를 강조하고, 빛의 콘트라스트를 이용하여 건축시설물을 강조함으로써 리듬감을 연출하였다. 색온도의 경우 성곽의 차가운 이미지를 보완하기 위하여 따뜻한 색온도의 광원을 사용하여 전체적 이미지를 안정적이고 부드럽게 표현하였다. 색도의 경우 전체적으로 황색의 색도가 나타났는데, 우리나라 전통건축에서 강조되어야 할 단청이나 부재를 위해서는 광원의 색채선정에 신중한 고려가 요구된다.
