Authors: Thathongkham Thanachaporn , Sonsuphap Rattaphong
Published: September 2023

The social green economy prioritises the use of green technologies and sustainable practices in economic activities, resulting in a reduction in environmental impact and an improvement in social well-being (Guo et al., 2020; Söderholm, 2020). Furthermore, the efficiency evaluation of the green economy development of forestry is related to the direction of forestry development and plays an important role in balancing economic and environmental issues within it (Huang et al., 2022). This study aims to explain forest community projects as a promising example of how sustainable development and the green economy can be achieved through community-based initiatives. A qualitative approach was applied. In-depth interviews were conducted with 10 key informants, employing purposive sampling. Content analysis and NVivo were adopted to analyse the data. The findings confirmed the potential benefits of community-based forestry initiatives, such as job creation, poverty reduction, and environmental sustainability. A forest community project can contribute to a green economy by implementing sustainable practices and utilising green technologies in its operations. By participating in carbon credit programmes, a forest community project can contribute to a green economy, mitigate the effects of climate change, and improve the economic prosperity and social well-being of the local community.

Authors: ALVARENGA MARCELA , D'Elia Ananda , Santos Graciane , Arantes Clara , Henning Frederico , Vasconcelos Ana , Solé-Cava Antonio
Published: September 2023

Phylogenetic gaps of publicly-available reference sequences are a major
obstacle for species identification and management, particularly in the
Global South, where economically important fisheries and conservation
flagship species often lack closely-related references. We applied
target-enrichment to obtain complete mitochondrial genomes of marine
ichthyofauna from the Brazilian coast lacking phylogenetically-close
references. Species were selected based on economic significance,
including three sardines (Dorosomatidae and Alosidae), three mackerels
(Scombridae) and nine croakers (Sciaenidae), as well as conservation
status, notably groupers and snappers of the Epinephelid family. Custom
baits were designed to enrich mitochondrial DNA across a broad
phylogenetic range of fishes. Sequencing generated approximately 100k
reads per sample, which were assembled in a total of 70 complete
mitochondrial genomes and include fifty-two new additions to databases,
including five species with no previous mitochondrial data. Departures
from the typical gene content and order occurred in only three taxa and
mostly involved tRNA gene duplications. Start-codons for all genes,
except Cytochrome c Oxidase Subunit I (COI), were consistently ATG,
whilst a wide range of stop-codons deviated from the prevailing TAA.
Phylogenetic analysis confirmed assembly accuracy and revealed signs of
cryptic diversification within the Mullus genus. Lineage delimitation
methods using Sardinella aurita and S. brasiliensis mitochondrial
genomes support a single Operational Taxonomic Unit. Target enrichment
was highly efficient, providing complete novel mitochondrial genomes
with little sequencing effort. These sequences are deposited in public
databases to enable conservation and management programs in Latin
America that rely on molecular data for species and genus-level
identification.

Published: September 2023

Wild pomegranate ( Punica granatum L.) is one of the most important
medicinal wild fruit crop and it is highly pollinated by wild insect
pollinators. So, study analyze various pollinating insects of Punica
granatum L. by using molecular method and a total of 24 species of
flower visitors were collected from Punica granatum from different areas
of Himachal Pradesh. Using mtDNA marker, the cytochrome oxidase subunit
sequence I (COI), about 17 pollinator insect species were characterized
and identified on the basis of COI sequence. BLAST analysis showed the
98 to 100% similarity with the existing genebank sequences. Nucleotide
composition revealed the average AT content was significantly higher by
72.56% than the GC content of 27.47%. Phylogenetic analysis of 17
different species of insect pollinators of Punica granatum revealed the
close phylogenetic relation between hymenopteran insect species in one
clade, whereas another clade showing relationship between Lepidoptera,
Coleopteran and Diptera. The study conclude that molecular
identification using species identification markers in the mitochondrial
region of COI play a critical role in study of genetic diversity,
genetic relatedness and phylogenetic analysis at species level and find
more strategies to conserve these pollinators for further research.

Introduction Tuberculosis (TB) in Nigeria is a serious disease
that is fast becoming deadly. In Nigeria, the burden and mortality of
the disease are high, making it one of the infectious diseases with a
significant public health challenge. Aim This paper is aimed at
examining the prevalence of TB in Nigeria, with emphasis on one of its
strains, namely XDR-TB, and factors promoting the disease and its
strains, among others. Methodology A literature search was done
about Tuberculosis in Nigeria using the keywords; ‘Drug Resistance;
Factors; Infection Rate; Mortality Rate; Nigeria; XDR-TB’ through
databases such as PubMed, ResearchGate, Google Scholar and World Health
Organization between a 10-year-period. Result We found that
Nigeria is among the 10 countries in the world with very high
tuberculosis incidence and mortality. A number of factors aid the
prevalence of the disease in Nigeria: poverty, malnutrition,
overpopulation and overcrowding, ignorance, stigma and discrimination,
etc. When it comes to the diagnosis of tuberculosis, Nigeria encounters
a lot of challenges. For instance, the country lacks access to quality
diagnostic facilities, the healthcare system is ill-equipped, and a good
number of the populace lacks the necessary awareness about the dangerous
nature of the disease. Conclusion The Nigerian government,
health workers, key stakeholders, and communities, both affected and
non-affected, should all come together to fight off Tuberculosis and its
spread in Nigeria. In order to be successful, the eradication effort
against TB in Nigeria has to permanently eliminate the causative agent
and risk factors everywhere in the country as pathogen prevalence is
globally reduced to zero, hence removing the risk of re-infection.

Authors: Dong Tra Van , Minh Nguyen Thu Nguyet , Son Ly Hai
Published: September 2023

With many practical applications print human life today such as
manufacturing surveillance cameras, analyzing and processing customer
behavior, …, the problem of face detection and head pose
estimation on digital images is being noticed by many researchers. A
large number of proposed deep learning models have state-of-the-art
accuracies such as YOLO, SSD, and MTCNN, solving the problem of face
detection or HopeNet, FSA-Net, and RankPmodelsodel used for head pose
estimation problems. According to big many state-of-the-art methods, the
process of this task consists of 2 parts face detection to head pose
estimation. These two steps are completely independent and do not share
information with each other. This makes the model clear print setup but
does not leverage most of the featured resources extracted in each
model. In this thesis, we proposed the PoseMultitask model with the
motivation to leverage the features extracted from the face detection
model, sharing them with the head pose estimation branch to improve
accuracy. Also, with the variety of data, the Euler angle domain
representing the face is large, our model can predict results in the
360° Euler angle domain. Applying the multi-tasking learning method, the
PoseMultitask model can simultaneously predict the position and
direction of the human head. To increase the ability to predict the head
direction of the model, we change the representation of the human face
from the rom Euler angle to vectors from the Rotation matrix.

Published: September 2023

Our personalities have a big impact on our daily life. It affects how we
think, feel, act, and express ourselves and how our mental health is
affected. The work will make use of the Myers-Briggs Personality Type
Dataset from Kaggle (MBTI). The Myers-Briggs 16 personalities, also
known as personality types, are a subset of the MBTI. The four
factors—introversion versus extraversion; sensing versus intuition;
thinking versus feeling; and judging versus perceiving—are used to
classify human personality. The 16 personality types of the MBTI are
formed from these four fundamental dimensions. In our work, we apply
different machine learning algorithm on the MBTI dataset and do a
comparative study with our proposed model based on CNN+BiLSTM along with
CPSO optimizer on MBTI dataset. CPSO optimizer is based on the social
behaviour of the animals. Based on the idea of animal swarm intelligence
displayed in flocks and shoals, this method sought to optimize nonlinear
continuous functions. In juxtaposed with other state-of-the-art
techniques, the CNN+BiLSTM with CPSO optimizer model outperformed well
with 93.85% accuracy, 93% precision, 93% recall, and 89.99% F1
Score.

Published: September 2023

Purpose The purpose of this study is to understand the amenity perceptions and tourism activities of beach space users and draw implications for tourism activities in beach spaces.
Methods Sample data were collected through a questionnaire based on amenity perception factors and tourism activity types derived through theoretical review. Empirical analysis was conducted through cluster analysis and importance-performance analysis on the sample data.
Results It was confirmed that beach space users can be subdivided into high-awareness, low-awareness, moderate-awareness, and partially-awareness groups according to differences in amenity perception. In addition, through the importance-performance analysis, it was confirmed that the natural landscape viewing type and shopping/restaurant type are activity types with both high performance and high importance, the leisure sports type and humanistic landscape viewing type are activity types with both low performance and low importance, and the experience type is an activity type with high performance but low importance. Finally, through the importance-performance analysis by cluster, it was found that the importance and performance of tourist activity types of beach space users differed according to the level of amenity perception, and there were significant differences by cluster, especially for leisure sports and experience types.
Conclusion While existing policy and technical considerations are important for understanding beach tourism, it is necessary to understand tourists' amenity perceptions alongside these considerations. Therefore, it is necessary to actively utilize these amenity perceptions in beach tourism development.
An Exploratory Study for the Social Meaning of the Time Perspective in the Post-COVID-19 Era and Its Application to the Local Oral History Study in Tourism
Authors:   The Convergence Tourism Contents Society, Kim Ok Hee , Min Woong Ki
Published: September 2023

Purpose This study aims to analyze the time perspective of members of society in the post-COVID-19 era and how it changed their attitudes and behaviors and explore the meaning of tourism in the consumption of time resources with the function and role of local oral history study.
Methods The contents of the literature on the social composition process of time and its meaning were reviewed and analyzed to explore the possibility of developing local tourism resources based on local oral history. The historical meaning of time-related research was examined as an exploratory research before conducting tourism research based on local oral history. Some implications were suggested on how this social philosophical discussion in terms of humanities and social science could be applied to developing local resources in tourism, an applied science.
Results Local oral history study on local history and culture based on a new time perspective in postmodern society helps reflect on the forming and reconstructing of various cultural boundaries in the production and consumption of the local community. As the expansion of tourism based on various local oral histories helps tourists to combine one-dimensional regression to the past, reflection on the present, and imagination of the future, local oral history is given the broad sense of tourism resource development that mitigates cultural boundaries in the post-COVID-19 era.
Conclusion The reflection on local history that helps newly remember the characteristics of a region through local oral history helps develop convergence tourism which newly emerges in the production and consumption of the local community culture. Also, local oral history has important theoretical and practical social meanings as it is considered as a new type of alternative tourism to people and promotes an active reconstruction of human behavior.

Published: September 2023

Objective: To determine to what extent changes in plasma proteins, previously predictive of cardiometabolic outcomes, predict changes in two diabetes remission trials.

Research Design and Methods: SomaSignal® predictive tests (each derived from ~5000 plasma proteins measurements using aptamer-based proteomics assay) were assessed in baseline and 1-year samples in trials (DiRECT n=118, DIADEM-I n=66) and control (DiRECT n=144, DIADEM-I n=76) participants.

Results: Mean weight losses in DiRECT (UK) and DIADEM-I (Qatar) were 10.2 (SD 7.4) kg and 12.1 (SD 9.5) kg, respectively, versus 1.0 (3.7) kg and 4.0 (SD 5.4) kg in control groups. Cardiometabolic SomaSignal tests improved significantly (Bonferroni-adjusted p< 0.05) in DiRECT and DIADEM-I (expressed as relative difference in intervention minus control) as follows, respectively: liver fat (-26.4%, -37.3%), glucose tolerance (-36.6%, -37.4%), body fat percentage (-8.6%, -8.7%), resting metabolic rate (-8.0%, -5.1%), visceral fat (-34.3%, -26.1%) and cardiorespiratory fitness (+9.5%, +10.3%). Cardiovascular risk (measured by SomaSignal tests) also improved in interventions groups relative to control but significant only in DiRECT (DiRECT: -44.2%, DIADEM-I: -9.2%). However, weight loss >10kg predicted significant reductions in CV risk of -19.1% (CI -33.4 to -4.91) in DiRECT and -33.4% (CI -57.3, -9.6) in DIADEM-I. DIADEM-I also demonstrated rapid emergence of metabolic improvements at 3 months.

Conclusion: Intentional weight loss in recent onset type 2 diabetes rapidly induces changes in protein-based risk models consistent with widespread cardiometabolic improvements, including cardiorespiratory fitness. Protein changes with larger (>10kg) weight loss also predicted lower cardiovascular risk, providing a positive outlook for relevant ongoing trials.

Published: September 2023

Objective: To evaluate the relationship between social needs and metformin use among adults with type 2 diabetes (T2D).

Research Design and Methods: In a prospective cohort study of adults with T2D (n=722) we linked electronic health record (EHR) and Surescripts (Surescripts, LLC) prescription network data to abstract data on patient reported social needs and to calculate metformin adherence based on expected refill frequency using a proportion of days covered methodology.

Results: Adjusting for demographics and clinical complexity, 2 or more social needs (-0.046, 95%CI=-0.089,-0.003), being uninsured (-0.052, 95%CI=-0.095,-0.009) and while adjusting for other needs, being without housing (-0.069 95% CI=-0.121, -0.018), and lack of access to medicine/health care (-0.058 95% CI=-0.115, -0.000) were associated with lower use.

Conclusions: We found that overall social need burden and specific needs, particularly housing and healthcare access were associated with clinically significant reductions in metformin adherence among T2D patients.

Authors: Kına Hakan , Kuş Koral Çağlar , Demirtaş İsmet
Published: September 2023

Objectives: The aim of our study was to describe a surgical access to pterygopalatine fossa and Vidian canal using an endonasal endoscopic approach. We also intend to reveal the anatomical relations of the neurovascular structures in the surgical corridors and to determine the relationships between previously defined reference points in order to prevent surgical complications during surgical access to these regions. Methods: Our study was carried out between October-December 2016 in Cerrahpaşa Faculty of Medicine Microneurosurgery and Neuroanatomy Laboratory. A total of 7 silicon dye-injected cadavers (4 males and 3 females) were studied. 3D images were obtained by photographing the approaches applied to the pterygopalatine fossa and Vidian canal and related anatomical structures. Results: We succeeded in exposing and examining the pterygopalatine fossa and Vidian canal endoscopically in all samples. First, the posterior wall of the maxillary sinus was opened to reach the pterygopalatine fossa. The pterygopalatine fossa was divided into 3 anatomical compartments. The first layer encountered was the periosteum covering the pterygopalatine fossa. After removing the periosteum, the fat layer was revealed. Under the fat layer, the vascular compartment and finally the neural compartment were encountered. Conclusion: Our study revealed three-dimensional anatomical data related to the surgical margins involved in approaches to the pterygopalatine fossa and Vidian canal; and specifically defined various neurovascular structures encountered in these approaches. Our study provides information to decrease potential complications that may develop during endonasal endoscopic surgery. We conclude that as the anatomy of the pterygopalatine fossa and Vidian canal is known in details, the endonasal endoscopic approach is likely to become the standard method to access lesions in these regions.

Kegiatan dakwah di Indonesia mengalami gejolak yang begitu besar, dimana sosial media digunakan sebagai wadahnya. Kemudian, dakwah yang dilakukan dari satu individu merupakan kewajiban muslim Indonesia dan dunia. Penyebaran konten dakwah dalam dunia virtual seakan meresahkan para viewers muslim tentang keaslian dan keotentikan sumber konten yang disebarkan oleh sebuah akun di media sosial dari berbagai flatform.  Namun, melalui Tafsir Rahmat penulis melihat bahwa ada tawaran kebaharuan tentang otoritas dakwah virtual agar tidak terjadinya ekspansi ilmu yang cacat. Terlebih lagi, pemahaman yang beragam dari para content creator berpotensi mengadu domba dan menyebarkan propaganda di khalayak luas. Melalui kajian yang berbasis kepustakaan (library research) dengan menggunakan kacamata intertekstualitas yang dipelopori oleh Julia Kristeva akan tergambar pesan dan substansi tawaran H. Oemar Bakry dalam melihat problematika tersebut. Dengan demikian, tulisan ini bertujuan merespon tawaran baru dengan membuat sebuah lembaga di bawah nauangan pemerintah tentang otoritas dakwah virtual. Tujuannya untuk menanggulangi pesan-pesan dakwah yang sifatnya provokatif, tendensius, bias, memihak, subjektif, evokatif yang berseliweran di jagad maya. Hasil dari penelitian ini akan tergambar bahwa kajian ini telah menghasilkan temuan baru bahwa H. Oemar Bakry menawarkan makna akan dibentuk kelompok juru dakwah yang kuat, jujur, dan teratur. Fungsi dari juru dakwah yakni menjadi sumber referensi khazanah keilmuan Islam Indonesia.

Starting and Specialisation Ages of Elite Athletes across Olympic Sports: An International Cross-sectional Study
Authors: De Bosscher Veerle , Descheemaeker Kari , Shibli Simon
Published: September 2023

Talent development models are the frameworks that guide sports stakeholders in developing potential athletes, within which early specialisation and diversification remain contradictory strategies. This paper presents new insights into the starting and specialisation ages of world-class athletes in various Olympic sports. A total of 2,838 athletes from 13 nations and 44 Olympic sports were included in this study. The results show that world-class athletes started with their current sport at the age of 10.6 (±5.3) and decided to focus on this sport at the age of 15.6 (±5.0), with obvious variations in these ages across different sports. The study showed a moderate relationship between athletes’ starting and specialisation ages (r = 0.639), which demonstrates the variable duration of the multiple sport sampling period. This period, during which athletes pursue a variety of sports, lasts 4.9 years on average. There is a high degree of variation among different athletes in starting and specialisation ages, even within the same sport. All sports in the study can be classified into five categories based on a combination of their starting ages (early/intermediate/late) and specialisation ages (early/intermediate/late). The Developmental Model of Sports Participation provides the age guidelines for the categories. The five categories contain (I) early specialisation sports, (II) intermediate starting and specialisation sports, (III) late specialisation sports, (IV) late starting sports, and (V) late starting and late specialisation sports. The study concludes by proposing that there is a need for sport-specific talent development models with increased attention to each sport’s starting age, sampling period, and specialisation age.

Tulisan ini membahas tentang persoalan yang terjadi dalam bidang permakaman di Jakarta pada tahun 1960-an – 1980-an. Pada periode tersebut, Jakarta mengalami krisis lahan permakaman. Menyadari masalah ini, Pemerintah Daerah DKI Jakarta memberlakukan sejumlah kebijakan untuk mengatasinya. Namun dalam praktiknya, terjadi kontradiksi dalam upaya Pemerintah Daerah dalam mengatasi krisis permakaman. Tulisan ini menggunakan metode penelitian sejarah dengan memanfaatkan sumber surat kabar sezaman. Berdasarkan penelitian yang dilakukan ditarik kesimpulan bahwa (1) krisis permakaman yang terjadi di Jakarta bisa terjadi karena banyaknya orang mati dan harus dikubur setiap harinya, sedangkan petak makam semakin menipis; (2) Pemerintah Daerah DKI Jakarta memberlakukan sistem permakaman tumpang, pembatasan izin penggunaan tanah makam, hingga pembukaan lahan permakaman baru di pinggir kota untuk mengatasi krisis lahan permakaman; (3) terjadi kontradiksi, dimana ditengah upaya mengatasi krisis permakaman, banyak permakaman yang ditutup dan dibongkar untuk menyediakan tanah bagi pembangunan.

Adam Smith and Democracy
Authors:   Korean Association of International Association of Constitutional Law, Lee Hwanghee
Published: September 2023

The name of Adam Smith is inextricably linked with modern economics. The most fundamental goal of his academic life, however, was the study of the principles of law and government. He formally declared this goal, pursued it throughout his life, and wrote The Wealth of Nations as a partial fulfilment, contributing to his immortality as a thinker. Although Smith was not a scholar dedicated to the study of democracy, he did explore the principles of law and goverment, and his writings contain rich discussions of political decision-making issues from which we can infer his understanding of democracy. This paper reconstructs them through the lens of realising and limiting majoritarianism.
While Smith's view was that majoritarianism should be at the centre of political decision-making, and he emphasised the role of elections as a means of realising majoritarianism, this does not mean that the path to majoritarianism is limited to elections. Rather, this paper argues that Smith saw the role of public opinion in influencing public deliberation as an important means of realising majoritarianism. In this regard, Smith identified the problem of class bias in public opinion based on socioeconomic conditions as a reason for the adoption of mercantilism, and recognized the role of the state in addressing this problem. Smith's discussion has significant relevance to the problem of the limited political role of the people in today's democracies, and the need for the active exercise of political liberty to prevent the implementation of unjust policies that violate liberty.
At the same time, Smith also touched on the possibility of the limiting majoritarianism. Majoritarianism is typically realised through representative legislation, and Smith recognized the existence of a higher normative content that guided statutory law by regarding such parliamentary legislation as aiming to be consistent with the rules of natural justice that arise from the sympathy of human nature. Smith also emphasized the existence of the state's duty of equal treatment as a normative principle that guides legislation in the area of police. Essentially, Smith recognized that representative decision-making is constrained by more fundamental norms. On the other hand, by locating the source of this limitation in the moral principles or political will emanating from the members of the state as a whole, Smith is credited with showing that the limitation of representative decision-making and the ideology of majoritarianism may not be incompatible. By viewing a constitution based on popular sovereignty as a product of the will of the majority, being higher democratic law-making than ordinary legislation, Smith's position has a similar logical structure to the current debate that even if a constitution appears to limit representative legislation, it can ultimately be reconciled with the ideology of majoritarianism.
