The effectiveness of using the advanced seismic protection technology based on shape memory alloy (SMA) dampers to preserve a historical minaret is investigated. The proposed studied case, the minaret of Mansourah, is a seven century old minaret located in Tlemcen, Algeria. Its original height was of 47m, while nowadays, the monument is half destructed and its current height reaches the 40m. The proposed seismic retrofit is based on the technique that utilizes SMA wires as dampers for the upper flexible part of the minaret. The effectiveness of the proposed technique is numerically evaluated via non-linear finite element analysis using the structural software ANSYS. The effectiveness of the proposed device in mitigating the seismic hazard is demonstrated by the effective reduction in its dynamic response.

This paper summarizes the experimental vibration-based structural health monitoring study on a historical monument in Jordan. In this work, and within the framework of the European Commission funded project "wide-Range Non-Intrusive Devices Toward Conservation of Historical Monuments in the Mediterranean Area", a seven and a half century old minaret located in Ajloun (73 km north of the capital Amman) is studied. Because of their cultural value, touristic importance and the desire to preserve them for the future, only non-destructive tests were allowed for the experimental investigation of such heritage structures. Therefore, after dimensional measurements and determination of the current state of damage in the selected monument, ambient vibration tests are conducted to measure the accelerations at strategic locations of the system. Output-only modal identification technique is applied to extract the modal parameters such as natural frequencies and mode shapes. A Non-linear version of SAP 2000 computer program is used to develop a three-dimensional finite element model of the minaret. The developed numerical model is then updated according to the modal parameters obtained experimentally by the ambient-vibration test-results and the measured characteristics of old stone and deteriorated mortar. Moreover, a parametric identification method using the N4Sid state space model is employed to model the dynamic behavior of the minaret and to build up a robust, immune and noise tolerant model.

An important historical monument of Cyprus is an aqueduct that was built in 1747 to provide water to the city of Larnaca and to its port. Because of its importance to the cultural heritage of Cyprus, the aqueduct has been selected as one of the case-study monuments in the project Wide-Range Non-Intrusive devices toward Conservation of Historical Monuments in the Mediterranean Area (WIND-CHIME). Detailed drawings of the aqueduct obtained from the Department of Antiquities of Cyprus have been used for the development of a computational model. The model was fine-tuned through the measurement of the dynamic characteristics of the aqueduct using forced and ambient vibrations. It should be noted that measurement of the dynamic characteristics of the structure were performed twice in a period of three years (June of 2004 and May of 2007). Significant differences were noted and they are attributed to soil structure interaction effects due to seasonal variations of the water-level in a nearby salt-lake. The system identification results for both cases are presented here. This monument was used to test the effectiveness of shape memory alloy (SMA) pre-stressed devices, which were developed during the course of the project, in protecting it without spoiling its monumental value.

Korea began preserving and managing natural monuments in 1933 under the Japanese Colonization, but South and North Korea had to establish natural monument management policies separately because of the division after the Korean Independence. The purpose of this study is to compare and analyze the natural monument designations of South and North Koreas between 1933 and 2005 to introduce advanced polices for Oneness-Korea. The following are the results: According to data of December 2005, South Korea has 358 and North Korea has 474 natural monuments. North Korea has 116 more natural monuments than South Korea. In addition, over half of South Korea's designations are plants, whereas North Korea's designations are relatively well-balanced. Both South and North Korea designate plants(mostly trees) that are old and large. However, South Korea emphasizes the historical value of village forests, contrary to economic value in North Korea. Also, North Korea preserves many traditional fruit trees which have not been well-preserved in South Korea. As for animals, South Korea designates migratory wild animals by type and not by region to protect them at a national level, whereas North Korea designates the specific habitats of each type of wild animal. In addition, North Korea protects each region's cattle and chickens to preserve native traits of domesticated animals. Geologically, North Korea preserves 18 hot springs and 11 springs, whereas South Korea has none. Geographically, North Korea preserves 81 waterfalls, lakes, etc. In the conclusion, advanced natural monument management of South and North Korea is necessary to achieve effective preservation of natural monuments.

Natural Monument is a designated cultural property as part of the country. According to Article 2 of the Cultural Properties Protection Act, a national, ethnic and global heritage artificially or naturally formed, with a great historical, artistic, scientific and landscape significance is defined as a cultural heritage. Animals, plants, topography, geology, minerals, caves, biological products and special natural phenomena, having a great of historic, scenic and scientific value, are defined as the monument. According to Article 3 of Cultural Properties Protection Act, the conservation, management and utilization of National Heritage should be kept intact in its original form. So, Natural monuments are managing as retained its original form under the Basic Principles of current law. The highest population of coniferous tree in natural monument plant is ginkgo tree including 22 objects, followed by pines, junipers that order. And in case of broadleaf tree, there are zelkova trees, retusa fringe trees, pagoda trees, cork oaks, silver magnolias and etc. There are many of reported efficacy in available natural monument plants. The efficacy of plant species on pharmaceutical like anti-cancer, anti-diabetic, anti-obesity, antioxidant activity, neuroprotective, improves cholesterol, anti-inflammatory, liver protection and anti-bacterial efficacy, on cosmetics and beauty like the inhibiting formation of skin wrinkles, whitening effect, variety of materials and the efficacy of the proposed utilization of its various papers and etc have been widely reported. Before the Nagoya Protocol enters into force, the future role of the National Research Institute for Cultural Properties Administration of Cultural Heritage should be obtain a legal right to manage the social, cultural and national natural monument with emotional value to the plant genetic resource as a natural monument efficient ways to study and preserve traditional knowledge biological resources by securing a claim to the sovereignty of the material will be ready.

The results of the application of shape memory alloy (SMA) prestressing devices on an aqueduct are presented in this paper. The aqueduct was built in 1747 to provide water to the city of Larnaca and to its port. Because of its importance to the cultural heritage of Cyprus, the aqueduct has been selected as one of the case-study monuments in the project Wide-Range Non-Intrusive devices toward Conservation of Historical Monuments in the Mediterranean Area (WIND-CHIME). The Department of Antiquities of Cyprus, acting in a pioneering way, have given their permission to apply the devices in order to investigate their effectiveness in providing protection to the monument against probable catastrophic effects of earthquake excitation. The dynamic characteristics of the structure were determined in two separate occasions and computational models were developed that matched very closely the dynamic characteristics of the structure. In this paper the experimental setup and the measured changes in the dynamic characteristics of the monument after the application of the SMA devices are described.

In the past decades, effect of near field earthquake on the historical monuments has attracted the attention of researchers. So, many analyses in this regard have been presented. Tunnels as vital arteries play an important role in management after the earthquake crisis. However, digging tunnels and seismic effects of earthquake on the historical monuments have always been a challenge between engineers and historical supporters. So, in a case study, effect of near field earthquake on the historical monument was investigated. For this research, Finite Element Analysis (FEM) in soil environment and soil-structure interaction was used. In Plaxis 2D software, different accelerograms of near field earthquake were applied to the geometric definition. Analysis validations were performed based on the previous numerical studies. Creating a nonlinear relationship with space parameter, time, angular and numerical model outputs was of practical and critical importance. Hence, artificial Neural Network (ANN) was used and two linear layers and Tansig function were considered. Accuracy of the results was approved by the appropriate statistical test. Results of the study showed that buildings near and far from the tunnel had a special seismic behavior. Scattering of seismic waves on the underground tunnels on the adjacent buildings was influenced by their distance from the tunnel. Finally, a static test expressed optimal convergence of neural network and Plaxis.

2023년 문화재청은 60년간 이어져 온 '문화재' 체제를 '국가유산' 체제로 탈바꿈하고 있다. 이 과정에서 문화유산 개념발전의 역사맥락에 대한 연구의 필요성을 느꼈다. 국내에서 현재 사용하고 있는 문화유산과 관련한 개념들은 국외에서 수입한 것들이 많다. 그렇기 때문에 우선적으로 원산지에서의 개념발전 역사를 알아야 한다. 이에 본고에서는 문화유산 개념의 원산지로 주류를 이루는 유럽을 대상으로 삼았다. 특히 유럽 내에서도 프랑스를 선택하였다. 프랑스는 18세기 말 공화국을 설립한 이래로 일찍이 유럽의 기념물 개념에서 국민의 유산으로 새로운 지평을 열었기 때문이다. 본고에서는 프랑스의 역사 중 프랑스 대혁명기를 대상으로 삼았다. 프랑스 대혁명기 구체제가 붕괴되고 보호체계를 잃어버린 기념물들이 어떻게 다시 새로운 국민국가의 보호 테두리 안으로 들어갔는지가 본 연구의 탐구대상이다. 프랑스 정부는 기념물들의 보존을 위한 행정조직으로 기념물위원회 및 예술임시위원회를 탄생시켰다. 두 조직은 혁명과 전시상황 속에서 이념과 정치선전에 구속되었기 때문에 기념물 보존활동에 한계를 보였다. 하지만 그런 시대 분위기 속에서도 지침서를 통하여 보존원칙을 수립하였고 기념물을 바라보는 새로운 가치관을 만들었다는 점에서 의미가 있다. 특히 전국에 배포한 지침서 중 기념물들을 바라보는 시각에서 국민의 유산이라는 시각을 보였다는 것은 선구적이다. 이것은 이후 프랑스의 문화유산 개념발전의 새로운 방향성을 제시해주었다. 이 흐름 속에서 기념물, 역사기념물, 문화재, 문화유산으로 프랑스의 문화유산 개념은 발전해나간다. 프랑스 혁명기의 역사는 구체제의 붕괴로 인한 가치관의 혼란 속에서 이전 체제의 기념물들을 새로운 보호체계 속에 집어넣었다는 점에서 보편적인 시사점을 도출할 수 있다. 이는 분단국가로서 가치관의 혼란위험이 잠재되어 있는 대한민국의 문화유산 분야에도 시사하는 바가 있다.
