No full textBeberapa kaedah telah diwujudkan untuk menyukat pencemaran udara. Kajian ini dijalankan bagi menentukan tahap pencemaran udara di Bandar Baru Bangi menggunakan pendekatan penunjuk bio (liken). Sebanyak 14 stesen di Bandar Baru Bangi telah dipilih sebagai stesen persampelan dengan setiap satu stesen terdiri daripada tiga batang pokok. Kajian ini menggunakan kaedah persampelan kuadrat pada di mana diversiti liken yang hidup di satu-satu kawasan pada batang pokok diberikan skor mengikut piawai skor indeks liken. Skor yang telah diperolehi akan dikira dan dinilai, purata skor akan menunjukkan kualiti udara di stesen tersebut. Nilai lebih dari 10 menunjukkan kualiti udara yang sangat bersih, nilai antara 0-9 menunjukkan kualiti udara bersih dan nilai skor -1 ke bawah adalah kualiti udara yang kotor. Daripada eksperimen yang telah dijalankan didapati bahawa nilai skor minimum bagi stesen-stesen di kawasan Bandar Baru Bangi adalah Balai Polis Bangi dengan skor -1.58 dan nilai skor maksimum adalah kawasan Puncak Bangi dengan nilai 17. Nilai skor purata bagi kawasan Bandar Baru Bangi adalah 3.95. Ini menunjukkan bahawa kualiti udara di bandar tersebut adalah baik. Udara yang agak tercemar hanya ditemui di kawasan tertentu di Bandar Baru Bangi seperti di sekitar seperti Balai Polis Bangi, Kompleks Bangi Utama, Seksyen 12, di sekitar Kilang Hitachi dan stesen Komuter UKM sahaja. Pencemaran udara di kawasan tersebut yang berpunca daripada debu dan asap kenderaan bermotor, boleh dianggap tidak berbahaya
A systematic literature review on the forest health biomonitoring technique: A decade of practice, progress, and challenge
No full textThe approach for monitoring forest health such as canopy layer, air quality, soil texture has evolved in tandem with the advancement of new technology such as lab analysis, remote sensing etc. The application of biomonitoring techniques for example species diversity and morphological observation, on the other hand, has been positive and has made its own contribution to forest management. Many studies have been conducted in the last decade (2011–2021), which use the biomonitoring techniques in assessing the forest health status. Therefore, this study aims to systematically review the forest health biomonitoring techniques in the last decade. This study used the PRISMA guidelines as the protocol to search and analyze all the papers. This study selected 72 out of 538 papers for a thematic analysis which eventually identified four main biomonitoring techniques, namely: 1) diversity distribution, 2) morphological observations, 3) trace elements, minerals and physiological measurements, and 4) behavioral observations. The biomonitoring techniques applied to monitor forest health has evolved with numerous ways that can support existing technologies, as well as help educate people on the necessity of protecting and safeguarding the natural forest environment. This also will give more options to the authority in monitoring the forest health and not only focusing on technology

Deep Learning vs. Atlas-Based Models for Fast Auto-Segmentation of the Masticatory Muscles on Head and Neck CT Images
No full textBACKGROUND: Impaired function of masticatory muscles will lead to trismus. Routine delineation of these muscles during planning may improve dose tracking and facilitate dose reduction resulting in decreased radiation-related trismus. This study aimed to compare a deep learning model with a commercial atlas-based model for fast auto-segmentation of the masticatory muscles on head and neck computed tomography (CT) images.
MATERIAL AND METHODS: Paired masseter (M), temporalis (T), medial and lateral pterygoid (MP, LP) muscles were manually segmented on 56 CT images. CT images were randomly divided into training (n = 27) and validation (n = 29) cohorts. Two methods were used for automatic delineation of masticatory muscles (MMs): Deep learning auto-segmentation (DLAS) and atlas-based auto-segmentation (ABAS). The automatic algorithms were evaluated using Dice similarity coefficient (DSC), recall, precision, Hausdorff distance (HD), HD95, and mean surface distance (MSD). A consolidated score was calculated by normalizing the metrics against interobserver variability and averaging over all patients. Differences in dose (∆Dose) to MMs for DLAS and ABAS segmentations were assessed. A paired t-test was used to compare the geometric and dosimetric difference between DLAS and ABAS methods.
RESULTS: DLAS outperformed ABAS in delineating all MMs (p \u3c 0.05). The DLAS mean DSC for M, T, MP, and LP ranged from 0.83 ± 0.03 to 0.89 ± 0.02, the ABAS mean DSC ranged from 0.79 ± 0.05 to 0.85 ± 0.04. The mean value for recall, HD, HD95, MSD also improved with DLAS for auto-segmentation. Interobserver variation revealed the highest variability in DSC and MSD for both T and MP, and the highest scores were achieved for T by both automatic algorithms. With few exceptions, the mean ∆D98%, ∆D95%, ∆D50%, and ∆D2% for all structures were below 10% for DLAS and ABAS and had no detectable statistical difference (P \u3e 0.05). DLAS based contours had dose endpoints more closely matched with that of the manually segmented when compared with ABAS.
CONCLUSIONS: DLAS auto-segmentation of masticatory muscles for the head and neck radiotherapy had improved segmentation accuracy compared with ABAS with no qualitative difference in dosimetric endpoints compared to manually segmented contours
Valuation of Visitor Perception of Urban Forest Ecosystem Services in Kuala Lumpur
No full textUrban forests play a vital role in maintaining the city ecological balance and providing ecosystem services to citizens. Ecosystem services lead to better quality of life, better environmental quality, and more sustainable urban growth. However, many emerging nations have often progressed at the price of lowering and sacrificing forest coverage, which has a negative impact on the benefits that the public receives from natural green spaces. As a result, the goals of this research were to ascertain visitor impressions of urban forests in Kuala Lumpur, to assess the value assigned by visitors to urban forests in Kuala Lumpur, and to investigate the elements that impact the willingness to pay. A questionnaire-based field study was conducted on a total of 254 respondents among Taman Tugu Urban Forest visitors, Kuala Lumpur. The results show that visitor perceptions of regulating services, cultural services, and supporting services were positive, with high-level score values of 4.74, ±0.40, 4.69, ±0.37, and 4.70, ±0.50. Furthermore, provisioning services were perceived to be of moderately high level (3.49, ±1.12), and visitor perceptions of urban forest amenities were positive, with high-level scores (4.39, ±0.53). Overall, this indicates that visitors had a very good perception of Taman Tugu Urban Forest ecosystem services. However, when we looked at the factors that contributed to the willingness to pay for the conservation of urban forests and entry, only the perception of the amenities provided at Taman Tugu had a significant relationship with the willingness to pay. A total of 79.1% of visitors expressed their willingness to pay, for forest conservation, an average payment value of MYR 51.32 per year, while 65% of visitors were willing to pay, as entry fees at urban forests, an average payment value of MYR 3.07 per person. It can be concluded that visitors had a positive perception of urban forests in Kuala Lumpur and were willing to contribute for conservation and entry fee purposes. We hope that the findings of this research contribute to a better understanding of urban forest ecosystem services in Kuala Lumpur and visitor perception. In addition, this study could also be useful to policy makers to formulate a specific policy focus on urban forests by comprehensively and holistically including the monetary value of the ecosystem services provided, considering public opinion and needs, and performing financial allocation for conserving and managing urban forests. This is to ensure that the urban sustainable development goals and smart city aims can be achieved
Economic utopia of the Torah. Economic concepts of the Hebrew Bible interpreted according to the Rabbinical Literature
No full textHebrew Bible offers alternative Economic utopia for building Theocratic society. In this paper, various economic concepts and themes are presented, as found in the Hebrew Bible. These economic concepts include taxation, property rights, labor market, social policy, banking, years of Sabbath and Jubilee, and business cycles. Most economic issues of the Bible are found in the texts of Torah, also known as five Books of Moses. These texts are analyzed by using classical Rabbinical commentaries for better insight. Contrary to the modern Economic theory which is based on the assumptions of scarcity of resources and unlimited needs of consumers, Economics of the Torah is based on God’s resources which are enough for all true needs of His people.Hebrew Bible, History of Economics, History of Economic Thought, Ancient Israel, Judaism
Systematic Review on Ecosystem Services (ES) of Ecotourism in South-East Asia (ASEAN)
No full textEcotourism ecosystem services can rarely been identified specifically in detail. Hence, little is known about interactions and relationship between ecotourism and its services. We have chosen South-East Asia (ASEAN) as our case studies because of its multi-diverse ecotourism ecosystem. We conducted a systematic review of studies that aim to understand the relationship and interaction between the ecotourism ecosystem and its services to summarize research from this emerging topic and to identify the patterns for ecotourism ecosystem services in ASEAN from different case studies. The results show that 7 out 10 ASEAN countries have studied on ecotourism ecosystem services. Most studies indicated the importance of the services provided by the ecotourism sector as cultural (aesthetic, scientific research and recreational) and supporting (habitat conservation). Our review also found some limitations of this study: first, no data gathered from 3 countries (Brunei Darussalam, Vietnam and Myanmar) and second, the study only focused on monetary methods (WTP etc.) and third, calls for more studies and comparative studies to identify services provided by ecotourism sector in ASEAN. Finally, we discuss how our review fits into the Pakse Declaration 2016 and policy development to address climate change.Trudno szczegółowo określić usługi pełnione przez ekosystemy ekoturystyczne. Niewiele więc wiadomo na temat interakcji i związków między ekoturystyką a jej usługami. W naszych badaniach wybraliśmy kraje Azji Południowo-Wschodniej (ASEAN), ze względu na ich różnorodny ekosystem ekoturystyczny. Przeprowadziliśmy systematyczny przegląd, który miał na celu zrozumienie relacji i interakcji między ekosystemem ekoturystycznym i ich usługami, aby zidentyfikować wzorce usług ekosystemów ekoturystycznych w ASEAN na podstawie różnych studiów przypadku. Wyniki pokazują, że 7 na 10 krajów ASEAN przeprowadziło badania dotyczące ekoturystycznych usług ekosystemowych. Większość badań wskazywała na znaczenie usług świadczonych przez sektor ekoturystyki jako kulturowych (estetycznych, naukowo-badawczych i rekreacyjnych) oraz wspierających (ochrona siedlisk). W naszym przeglądzie występują także pewne ograniczenia. Po pierwsze, brak danych z 3 krajów (Brunei Darussalam, Wietnam i Mjanma). Po drugie, badanie dotyczyło tylko metod pieniężnych (WTP itp.). Po trzecie, przeprowadzone badania sugerują konieczność prowadzenia dalszych prac porównawcze w celu określenia usług świadczonych przez sektor ekoturystyki w ASEAN. Na koniec omawiamy, w jaki sposób nasz przegląd wpisuje się w Deklarację Pakse z 2016 r. i rozwój polityki dotyczącej zmian klimatycznych
