Evaluasi Penerapan Sistem Manajemen Keselamatan dan Kesehatan Kerja (SMK 3) pada Proyek Preservasi Jalan Simpang Siak Sri Indrapura – Mengkapan/Buton (MYC) di Kabupaten Siak

Occupational safety and health is an instrument that protects workers, companies, the environment, and the surrounding community from hazards due to work accidents. This protection is a human right that must be fulfilled by the company. K3 aims to prevent, reduce, even eliminate the risk of work accidents (zero accident). In the field of construction services, there are many problems regarding the not yet optimal implementation of the Occupational Safety and Health Management System (SMK3), while the implementation has not been optimal due to several factors. One of the activities that influence the success of the job is the capacity and capability of the service provider. Evaluation of service provider performance appraisal is the process of measuring, analyzing, and managing provider performance with the aim of reducing costs, reducing risk and directing continuous improvement in value and operations. This study seeks to evaluate the performance of service providers in implementing SMK3 based on the SMK3 Implementation Criteria using the AHP (Analytical Hierarchy Process) method. The research location is the Siak Sri Indrapura - Meng Kapan / Buton (MYC) Simpang Siak Road Preservation project in Siak Regency, Riau Province which is one of the construction projects that has a high risk of work accidents.

A high detail UAS-based 3D model of the Torre Benzalá in Jaén, Spain

The constant development of geomatics tools has driven the opening of their applications to multiple disciplines, including archaeology. The possibility of performing a 3D reconstruction of archaeological remains as well as a semantic classification of the 3D surface facilitates not only a better knowledge of the historical heritage but also an essential aid to the planning and development of restoration and preservation projects of this legacy. Different data exploitation strategies are needed to take advantage of the geospatial data provided by geomatics tools. In this paper, we have studied the current state of conservation of a medieval tower, Torre Benzalá in Jaén, southern Spain. The interesting thing about this study is that very high resolution RGB images, taken by a drone, have been used in order to show the current degree of deterioration of the tower, providing accurate and precise documentation of the current state. Thus, a highly detailed 3D reconstruction of the tower has been carried out. A dense point cloud was generated to obtain a digital elevation model (DEM) to identify and quantify the most critically deteriorated areas. The results are useful for the development of an architectural maintenance and restoration project to preserve this archaeological legacy.

Preserving and Tuning into Radio Stations at Historically Black Colleges and Universities

ABSTRACT The United States boasts more than 100 historically black colleges and universities, and 29 of those institutions own and operate radio stations targeted for the HBCU Radio Preservation Project. The lack of minority ownership in broadcasting has been a long-standing issue facing the industry. This study focuses on the radio stations targeted for the HBCU Radio Preservation Project, their web presence as well as how the journalism and mass communication programs integrate the stations in the curriculum. Findings suggest that most of the stations are operated as noncommercial, and provide community programming and outreach beyond the campus. All of the stations in the sample have a web presence and more than half have some affiliation with National Public Radio.

Cost analysis of Occupational Health And Safety (K3) on the Road Preservation (Case Study : Road In Kendari City – Kendari City Boundary)

The purpose of this study was to determine how much the application of K3 and to analyze the cost of K3 on the road preservation project within Kendari City - Kendari City boundary.
 The results showed that the level of use of PPE in road preservation work in the city of Kendari did not meet the standards for the level of use of PPE / included in the less category. This is because the average value of the level of use of PPE in road shoulder work, asphalt Ac-Wc and Talud is 60%.
 The cost required for the implementation of Occupational Safety and Health (K3) on the Road Preservation project. The required K3 cost based on the unit price of the regulation is IDR 266,645,950.00 or around 2.17%, while the cost based on field prices is IDR 257,953,950 or about 2.10%. The percentage of K3 costs at the regulation price is greater than the percentage of K3 costs at field prices with a difference of 0.07% or Rp. 8,692,000.00.

Assessment of Heritage Preservation Projects in The Old City of Damascus from The Perspective of International Conventions and Standards

تمتاز مدينة دمشق القديمة باحتوائها على العديد من الأسواق والاحياء العريقة والمساجد والكنائس والخانات والشوارع المرصوفة، وتمتاز بأوابدها وابنيتها التي تعكس أسلوب العمارة الدمشقية، لذلك تهتم الجهات السورية المسؤولة بحمايتها وإقامة مشاريع لحفظها. وعلى الرغم من تنفيذ الدولة للعديد من مشاريع الحفاظ على الموروث الثقافي في دمشق القديمة الا انه لم يتم إجراء أي دراسة لتقييم مدى توافق هذه المشاريع مع توجيهات وأسس المواثيق والمعايير الدولية. لذلك جاءت هذه الدراسة كرسالة ماجستير لتناقش بعض مشاريع الحفاظ على التراث العمراني في مدينة دمشق القديمة، وتقييمها من منظور المواثيق والمعايير الدولية لمعرفة المشاكل الناتجة عن الأساليب والمنهجيات المتبعة في عمليات الحفظ وتوفير قاعدة بيانات معلوماتية حول تقييم أساليب الحفظ المتبعة في دمشق القديمة. وقد تم اختيار مجموعة من المشاريع وهي مشروع دمشق القديمة بدون سيارات، ومشروع ترميم سوق مدحت باشا، ومشروع ترميم بيت القوتلي، وبيت السباعي، وبيت نظام، وتم اعتماد مجموعة من معايير التقييم التي تناولت بعضها التدخلات الفنية والمواد المستخدمة وبعضها الآخر التدخل والحفاظ. وقد توصلت الدراسة بعد التقييم وفقاً للمعايير إلى نتائج عدة، أهمها الحاجة الى الحفاظ على العلاقة بين دمشق القديمة داخل الاسوار ومحيطها. ويوصي البحث بضرورة الربط بين المديريات المسؤولة عن دمشق القديمة، ووضع خطة إحياء شاملة ومتكاملة مبنية على المعايير الدولية.

Evaluating the Implementation of the Complete Streets Policy in Louisiana: A Review of Practices and Projects in the Last 10 Years

The goal of Complete Streets is to accommodate all road users and draw attention to the needs of those who are vulnerable. In the last 10 years, thousands of local/regional/state agencies in the U.S.A. have adopted Complete Streets policies. However, it is not clear how successfully these policies have been implemented and to what extent agencies have achieved related policy goals. Responding to the call from Louisiana, the research team reviewed the state’s practices and projects over 10 years to evaluate whether/how the state transportation agency has made progress toward the adopted policy goals. Based on the practice review results, much progress has been made compared with where the state started in 2010. However, shifting agency culture to balance multimodal needs is a long-term process. Continuous effort is needed to train and educate staff in both the state agency and local governments. Based on the project review results, improving the state’s project management system could facilitate periodic performance reviews on a more frequent basis. From the perspective of influencing the built environment, more attention should be given to preservation projects to improve routine integration of low-cost safety measures and support decision-making on roadway reconfiguration needs. Although the review was conducted for Louisiana specifically, the review procedure and recommendations may be applicable to other states and government agencies facing challenges in Complete Streets policy implementation.

Recreation Valuation of Caving Using Travel Cost Method in Capisaan Cave System, Nueva Vizcaya, Philippines

The value of recreation services generated by the caving activity in Capisaan Cave System (CCS) in Kasibu Nueva Vizcaya was estimated using the zonal travel cost method, a revealed preference valuation technique. Data were collected through on-site and online visitor surveys with a total of 429 respondents. Regression analysis using the different functional forms of data was explored to estimate the demand function of the site. Results show that transformation of data in their natural log forms gave better linearity between variables, with estimated recreational values of the cave system ranging from PHP 1,703,500–2,098,300/yr and total access value of PHP 8,351,298–8,746,098 based on 2018 visitation data. These estimates provide a measure of the value of benefits derived from the ecotourism services of the CCS. These values need to be communicated to the stakeholders of CCS and its neighboring communities to increase appreciation for its recreation value. They should also be considered in evaluating development and preservation projects intended for the CCS.

Predicting Pavement Structural Condition Using Machine Learning Methods

State departments of transportation recognize the need to incorporate pavement structural condition in their pavement performance models and/or decision processes used to select candidate projects for preservation, rehabilitation, or reconstruction at the network level. However, pavement structural condition data are costly to obtain. To this end, this paper develops and evaluates the effectiveness of two machine learning methods, Random Forest (RF) and eXtreme Gradient Boosting (XGBoost), for predicting a flexible pavement’s structural condition. The aim is to be able to predict whether a pavement section’s structural condition is poor or not based on Annual Average Daily Traffic (AADT), truck percentage, and speed limit. The structural condition of a pavement is considered poor if the Surface Curvature Index (SCI12) is above 3.3. The models are developed using 950 miles of Traffic Speed Deflectometer (TSD) data collected along 8 primary routes in South Carolina. The performance of the machine learning models was compared with that of a logistic regression model. When the trained models are applied to the test data, the prediction results indicated that the XGBoost and RF models outperform the logistic regression model by 12% and 8%, respectively. XGBoost outperformed RF by 4%. With XGBoost found to be the best among the three models evaluated, its performance was examined using other poor structural condition threshold values; its prediction accuracy is found to be robust across the different scenarios. AADT and truck percentages are found to be significant factors whereas speed limit has no effect on a pavement’s structural condition.

Politics of urban cultural preservation and regeneration: the case of South Korea and Taiwan

ABSTRACT This paper compares the cases of Seoul, Taipei and Keelung to illustrate the dynamics of the local state in leading the process of cultural preservation. We argue that political ambitions of local leaders, driven by economic and political incentives to boost local development, create policy networks centered around local bureaucracies. Various actors, such as local political elites, local bureaucracies, civic groups and developers, are involved in the process of political and economic entangling. The cultural preservation projects are thus the reflection of the political interpretation of memory, as well as the realization of local state power to implement innovative goals of urban rebranding and regeneration. The Korean and Taiwanese cases demonstrate that political functions, such as regime legitimacy and the formation of new identities, have been instrumental in the process of urban regeneration. This paper brings the “politics” back into local developmentalism in the democratic societies of South Korea and Taiwan. This paper also argues that central-local relationship matters as well. The local developmental states are not totally isolated from political entanglements at the central level. Policy supports from the central level are mainly out of political concerns to legitimize ongoing efforts of historical reconstruction and re-interpretation.

Authenticity or homogeneity? Contextualising the urban revitalisation of a post-industrial landscape through the Red Brick Landscape Preservation Project in Seoul

This study analyses the case of the Red Brick Landscape Preservation Project at Seoul Forest Park Alleys, an urban revitalisation project implemented between 2018 and 2021, based on the idea of authenticity and post-industrial landscape. The following issues on site were determined based on site analysis and data mapping. First, there is a discrepancy in preservation, use, and implementation. Second is the selective nature of the Red Brick Landscape Preservation Project, as it is adapted to the city branding strategy, which may not always prioritise the actual site-specific contexts. Third, the attempt to represent the authenticity of the Red Brick Landscape Preservation Project in the Seoul Forest Park Alleys with a red brick landscape seems unfounded. Instead, red bricks were adapted to represent an image of authenticity seen elsewhere. Finally, this projection of authenticity from elsewhere onto the site is difficult to avoid for post-industrial landscapes because of the nature of industrial cities. Considering that the post-industrial landscape remains in high demand worldwide, the criticisms in this article may extend beyond the case in point. This study concludes with recommendations for future studies of the site.

Leviathan’s Architect: Urbicide, Urban Renewal, and the Right to the City in Turkish Kurdistan

Urban warfare exacts a grim toll on city life as combatants target civilians and civilian infrastructure, appropriate space, and try to erase culture and memory. Often, however, it is the post-conflict razing and reconstruction that caps this violent re-ordering of urban life. This article explores securitized development of cities in Southeastern Turkey in the wake of recent armed strife between Kurdish fighters and Turkish security forces. Case studies of Sur/Diyarbakır and Nusaybin show an overlord state leveraging post-war blight to remake society from the ground up. Targeting the physical as well as social contours of cities, Ankara has displaced residents, redirected access and flow, and intensified surveillance and control. The upheaval has been disorienting for residents, but in other ways it has sharpened Kurdish identity and agency. Historical preservation and memory projects, cultural commemorations, and new models of post-war urbanism underscore the right to a city that reflects civil society rather than one that tries to reengineer it in the image of the state.

Fragile Heritage: Historical Glass Plate Negatives at the Astronomical Observatory of Palermo

The Astronomical Observatory of Palermo still operates in the original 18th-century premises where a wealth of heritage has stratified, including historical instruments, books, archival documents and photographs. Among the photographic collections a number of glass plate negatives have survived several moves and internal rearrangements of the spaces, especially of the library and archive. Some years ago, a fruitful cooperation with the leaders and students of the course on Cultural Heritage Conservation of the University of Palermo provided an opportunity to design and carry out a preservation project to clean, stabilize and digitize all the historical photographic negatives of the collection. The project was carried out by the students under the tutelage of an accredited conservator and allowed, with a small investment, to dramatically increase the life expectancy of such an invaluable piece of heritage and to make it safely accessible to scholars.

A Comparison of Extracted Dominant Colours of Twelve Cosmopolitan Cities

Abstract: Metropolitan cities are large multi-cultural urban areas. Their colour schemes, which contribute to their unique identities, are influenced by factors, such as when the city was established, climate, city ordinances, and cultural heritage. City colours also evolve overtime due to new construction materials, innovative building designs, and urban development. The objective of this study is to determine if there are similarities in dominant colours for twelve metropolitan cities spanning six continents. They include Cairo, Cape Town, Singapore, Tokyo, Perth, Sydney, London, Madrid, Mexico City, New York City, Buenos Aires, and Lima. The Fuzzy C-Means (FCM) colour extraction technique was used to extract five dominant colours from images of these twelve cities. The extracted dominant colours were outputted as hexadecimal codes with their corresponding names obtained from the color-name.com website. Results show that some of these cities have similar dominant colours. Two colours, cobalt blue and sonic silver, are found in 25% of the cities. Furthermore, ten colours are present in pairs of cities. Most notably, some cities share two of the five dominant colours. Mexico City and New York City both have eerie black and platinum in their colour schemes, while Singapore and Lima share Charleston Green and Gainsboro. Cape Town and Perth both have light cobalt blue and sonic silver in their colour patterns, while Madrid and Buenos Aires share khaki and shadow colours. Dominant colours identified as a result of this investigation could be used to produce colour palettes for these cities. Since colour is an important component of urban development and preservation projects, the ones that incorporate aspects of existing colours would create buildings that are harmonious with the cultural heritage as well as the overall colour scheme of this city.

Oudlājān documentation project: a voluntary challenge

ABSTRACT Oudlājān, the historical urban core of Tehran, has exquisite houses, mostly from the Qajar era. It is suffering from neglect. Precious buildings have collapsed, together with their tangible and intangible heritage. Despite decades of interest in this neighbourhood, there is no complete and methodical inventory and documentation of all the individual properties. The Oudlājān Documentation Project (ODP) is a voluntary effort, to create a data archive for possible future preservation, rehabilitation, conservation, and restoration projects for this built heritage.

Role of urban preservation to achieve sustainable urban development – Preserving Erbil Citadel as case study

Cities in the world transformed from traditional aspects to sustainable aspects, this transformation need to consider preserving urban heritage as one of the goals of sustainable development agenda 2030. From this view, the research problem appears from the lack of clarity of preserving urban heritage as part of culture and urban sustainability. So, the research aim tries to reach the role of urban preservation to achieve goals of sustainable urban development, and chose Erbil citadel as the first implemented preservation project in Iraq, which adopted 2014 in the world heritage list by UNESCO, which need to integrate preserving urban heritage with sustainable development goals. That will lead to prevent loss of heritage stock, and integrate all goals that contribute to revive the historical buildings in the life of city and society. The research concludes the continuation of this cultural heritage and its effectiveness in completing principles of sustainable development, especially, resettlement of the original inhabitants who removed from it, to be as integrated global model for the traditional human natural and cultural life, and integrated with surrounding urban fabric, instead of their decision to converted citadel as a museum.

Hydrological Characteristics and Trophic Status as Dominant Drivers of Rotifer Community Composition in Artificially Created Riverine Wetlands.

Simple SummaryIncreased public awareness of wetlands and the importance of their conservation stipulated various preservation or improvement projects. In 2012, riverine wetlands were created in the Nakdong River in Korea to replace those damaged or destroyed by the River Refurbishment Project, but they could not be maintained as functional wetlands, owing to the long-term neglect and lack of management. A previous survey detected various problems in these wetlands, including insufficient in/outflow function, shore instability, and difficulty in introducing appropriate water sources, which cause nutrient accumulation and algal blooms. The in/outflow functions of the mainstream and tributaries were hampered by soil and plant deposition. These chemical changes influenced the community composition of rotifers. In particular, three rotifer species—Brachionus, Keratella, and Trichocerca—were mainly distributed in wetlands with relatively high nutrient concentrations (total nitrogen and phosphorus). Therefore, the rotifer community can be used as an indicator of the nutritional status of a wetland, and the functional state of the wetland can be understood through continuous monitoring of rotifers.Hydrological characteristics of freshwater ecosystems are powerful determinants of the distribution of biological communities and changes in environmental factors. This study identified relationships between the wetland environment, rotifer community, and hydrological factors for 48 wetlands, to determine their impact on wetland conservation and management. Different hydrological factors produced different wetland environments, which influenced the rotifer community composition. The wetlands with “poor” “in/outflow function” and “shore stability” levels showed high conductivity, turbidity, depth, and concentrations of total nitrogen, total phosphorus, and chlorophyll a. In contrast, the dissolved oxygen levels and velocity were the highest in wetlands with “good” in/outflow function and shore stability variables. The nutritional status of each wetland affected the composition of the rotifer community. Some genera (Keratella, Brachionus, Anuraeopsis, Trichocerca, and Philodina) were found in wetlands with high concentrations of total nitrogen, total phosphorus, and chlorophyll a, and high turbidity and depth. In contrast, Ascomorpha and Ploesoma were found in wetlands with high dissolved oxygen levels and flow velocity. High densities of Lepadella, Lecane, and Testudinella were found in wetlands completely covered by macrophytes. The rotifer community distribution can be used to understand the trophic, current functional, and environmental status of wetlands.

THE CHALLENGE OF THE EMERGENCY REMOTE TEACHING IN THE EDUCATION OF ART CONSERVATORS. EXPERIENCES AND REFLECTIONS

COVID-19 pandemic and the measures to constrain it have influenced, among others, every dimension of the cultural heritage; from research, conservation and preservation projects to training and education. The closure of training buildings and campuses, the cancellation of face-to-face classes and labs and other learning experiences forced a shift to emergency remote teaching. Especially, for art conservators education, as the field of heritage conservation is powered by art history, technology and science, any deceleration has an important impact on it. Moreover, conservators have to be in contact with the real object, to be present physically in the archaeological sites, to interact with the material of the monuments and traditionally they work very close to them. The closure of the education domain deprived conservation students from the physical contact with the objects, but had fostered the digital transformation of the heritage sector, as well as the academic conservation education. The goal of this paper is to discuss advantages and weaknesses of emergency remote teaching comparing to face-to-face teaching and online teaching too, as well as to record the experience of the remote teaching in the Department of Conservation of Antiquities and Artworks and the opportunities emerged for the curricula of the Department.

Alexandria, Kom el-Dikka, season 2021

Excavations of the central part of the Kom el-Dikka archaeological site in Alexandria have reached early Roman levels and the current investigations of the PCMA UW expedition are focused on completing the excavation of some of the partly uncovered architecture. The southwestern part of House FA was explored, uncovering two fragments of colourful mosaic floors. Building chronology was established based on finds from two deep stratigraphic probes dug inside the structure. The main phases of occupation of House FA turned out to be comprised in a period between the 1st and 3rd centuries CE. The archaeological part of the program was accompanied by current preservation and maintenance work that the team is tasked with in different parts of the site; necessary preservation projects were undertaken this year in the theatre, the portico in front of the theatre and the early Roman buildings in the central part of the site. The mosaics on display in the mosaic shelter have also undergone cyclical conservation treatment.
