Design of an orchid conservation trail in Ixtaczoquitlán, Veracruz, Mexico
Authors: Hernández-García A. , Baltazar-Bernal O. , Zavala-Ruiz J.
Published: August 2024

Objective: To raise awareness about the ecological importance of orchids and to promote the species commercialized by a company focused on their production through the design of a trail.
Design/Methodology/Approach: A diagnosis of the plot was carried out to identify its characteristics and points of interest. A trail was designed to connect the most outstanding points. Native trees, which are the habitat of orchids, were subsequently planted to establish the outdoor collections.
Results: The appeal of the place and the established phorophytes were taken into consideration to design the trail. Likewise, recommendations were made on what species of orchids should be planted in each station along the trail.
Study Limitations/Implications: Evaluating visitor experience is pending. The trail lacks infrastructure for people with disabilities. The trail is located in an area subjected to anthropization and it will take several years before orchids can be established on the trees planted in July 2023.
Findings/Conclusions: Trails are a useful tool to promote the conservation of native orchids; however, under anthropization conditions, it should be subjected to a systematized implementation to provide the climate and phorophyte conditions necessary for the survival of orchids.

Authors: Cruz-Lázaro Luis M. , Banda-Ortiz Humberto , Vivanco-Palacios Paulina I.
Published: August 2024

Objective: To determine if the Mexican, Canadian, and American agricultural industries are cointegrated.
Methodology: Six cointegration tests were carried out between the Mexican, Canadian, and American agricultural, forestry, fishing, and hunting industries, as well as the Mexican animal husbandry and exploitation sector. The USA was the independent variable in all cases.
Results: The Mexican sector, with an α of 5% (with and without trend) is not cointegrated with the USA and Canada, while Canada and the USA, with an α of 5% (with and without trend) are cointegrated.
Study Limitations/Implications: The agricultural sector of the three countries were not analyzed separately and the Engle-Granger causality test was not used. Although some products from Mexico's agricultural sector have managed to make inroads in the USA and Canada, further advances are still possible. Therefore, there are areas of improvement for Mexican products. Likewise, NAFTA and the USMCA/CUSMA have failed to achieve their objective of cointegrating the agricultural sectors of the three nations.
Conclusions: The Mexican sector was not cointegrated with the American and Canadian sectors during the analysis period —i.e., the Mexican sector is not influenced by and does not have the same long-term behavior (with delays) than the USA and Canadian sectors. However, the Canadian sector is cointegrated with the USA sector —i.e., the Canadian sector is influenced and has the same long-term behavior than the USA sector.

Providing Intradialytic Parenteral Nutrition Therapy Does Not Improve Anthropometric Status in Hemodialysis Patients with Malnutrition
Authors: Suryantoro Satriyo Dwi
Published: August 2024

Background: Malnutrition is prevalent in hemodialysis patients and significantly impacts prognosis. It can result from reduced food intake and protein loss during hemodialysis. Nutritional status is determined through anthropometric examinations, which include upper arm circumference (UAC), body mass index (BMI), hand grip strength, bicep, and tricep fold thickness. Laboratory examinations like total cholesterol and Malnutrition Inflammation Score (MIS) or Subjective Global Assessment (SGA) are also used. Intradialytic Parenteral Nutrition (IDPN) is expected to maintain or improve the nutritional status of hemodialysis patients. Objective: This research examines the impact of parenteral nutrition therapy on the anthropometric status of malnourished hemodialysis patients. Methods: This cross-sectional study, a sub-analysis of a larger nutritional therapy study, involved 24 hemodialysis patients experiencing malnutrition based on SGA B and C criteria with 1-10 years of hemodialysis. IDPN therapy was provided, and anthropometric measurements and total cholesterol were taken at baseline and three months after nutritional therapy. Data processing used comparative statistical analysis. Results: The mean age was 45.33 years, with 14 males and 10 females. After 3 months, there were no significant differences in UAC (mean difference = 0.13; p = 0.69), BMI (mean difference = 0.13; p = 0.50), hand grip strength (mean difference = -0.96; p = 0.282), biceps skinfold thickness (mean difference = 0.13; p = 0.69) and triceps (mean difference = 0.59; p = 0.134) or total cholesterol (mean difference = -1.5; p = 0.71). Conclusion: IDPN therapy for 3 months did not improve the anthropometric status of hemodialysis patients with malnutrition.

Collective strategy of small dairy economic units operating in an oligopsonistic market
Authors:   Universidad Panamericana, López López Gemma Cithlalli
Published: August 2024

This article addresses a problem in the Mexican dairy industry and involves stake-holders upon whom the operation of this sector depends. I am referring to the small dairy units, which have long been in a vulnerable situation due to their operating in an oligopsonistic market where the processors hold dominance. A lack of technology, resources, training, business knowledge, project entrepreneurship, along with isolat-ed operation, exacerbates the situation. Since the late 20th century, cooperation has emerged as a strategy for small and medium-sized economic units to survive in a chal-lenging market and to improve their well-being. The work aims to highlight a model of business cooperation between dairy units. By pooling resources and efforts, produc-tive development is strengthened with the goal of achieving survival and in order to contribute to regional development. The case study of Cooperative Prolea in Acatic, Jalisco is used

The Value of Pancasila as an Ideological Based for the Development of the Legal System in Indonesia
Authors: Hartono Bambang
Published: August 2024

Indonesia is a multicultural society with personal and group consciousness. Legal progress in Indonesia was influenced by cultural and community awareness. Indonesia is a multicultural culture with diverse legal awareness. Although Indonesia has many cultures, the equation should be applied to construct a legal union. Pancasila is the intellectual foundation for Indonesia's unitary state; hence, passing a national law must be founded on it and the 1945 Constitution as the supreme rule to achieve national unity. This study will show that the law enacted today does not reflect Pancasila and impressed liberalism because it is draughted and enforced on the basis of normative thinking rather than empirical thinking about the case and plural society. Methodology Pancasila and culture's role in legislation that impacts the other will be thoroughly examined in this article. Thus, for the welfare of the nation and public awareness of the law, this study will explain the need for systemic and continuous legal systems that reflect the Indonesian nation, namely Pancasila-based legislation.

Authors: Rahman Izzat Fadhlur , Lissimia Finta
Published: August 2024

A hospital is a medical facility that aims to improve the quality of life of the community through the process of preventing, treating, and medicating health problems. The mix of hope for recovery and the risk of death creates the impression that the hospital is a scary place, which affects the patient's psychological condition and causes other problems. Biophilic is an architectural approach that aims to have a positive influence on the human psyche by fulfilling his instinctive need for affiliation with nature. This study aims to understand the application of the biophilic concept at Pondok Indah Bintaro Hospital. The method used is descriptive qualitative with analysis based on the theory of 14 biophilic patterns by Browning, Ryan, and Clancy, through a hospital with a biophilic architecture that represents natural systems at a site scale through nature in space. At the building scale, biophilic is applied through architectural details that analogize natural forms (nature analogues), as well as natural spatial characteristics that affect human perception (nature of space).

Authors: Dharmatanna Stephanus Wirawan , Wijaya Elvina Shanggrama
Published: August 2024

The developments of information technology have affected architectural education methods significantly, especially in the usage of architectural design softwares throughout the design process. Proficiency to operate certain software has become one of important considerations in professional architectural practice, because such skill will affect the whole process and outputs. With excellent skill, one can visualize and communicate design more effectively, rather than other individuals that use more updated software features but still learning to operate them. On the other hand, the learning process in architectural design studios always has a theme that can be classified to certain building typologies. This research aims to study the relation between building typology and software preferences in each design stage, from students point of view. The targeted students are the ones in third and fourth year of study, where the digital media are utilized in the studio process. The data obtained from questionnaires will be analyzed further using descriptive and correlational analysis. The findings from this research will serve as an input for the development of architectural education curriculum, regarding the most relevant and beneficial architectural software in each design process, from students' preferences.

Published: August 2024

The amount of mushrooms cultivated around the world is constantly increasing, and the most commonly consumed species in Europe is the white button mushroom (Agaricus bisporus). Mushroom producers are facing a permanent challenge to provide the labour for harvesting, with increasing wage demands. Due to high market quality requirements, early automatized technologies are currently not able to replace manual picking. Our research therefore aims at facilitating the automated picking of button mushrooms and improving the technology via image processing. We aim to develop a method that can select the right size of mushrooms from field images and produce their picking position. We used Python programming language, along with the OpenCV and NumPy libraries, to implement image processing on real scenario images. The development considered factors such as fused- or overlapping mushroom heads, emergence of mushrooms from under caps, fallen or laterally visible stumps, cover soil contamination, and white mycelia which make detection significantly more difficult. We managed a solution for handling fruiting bodies that extend beyond the edge of the image due to the small field of view. The results indicated that the quality of photographs is crucial for the program's performance, as improper lighting, the presence of shadows. The efficiency of the algorithm was significantly affected by the 82% accuracy of the OpenCV Watershed segmentation algorithm, which in some cases could not separate objects. The program processed the images at an average speed of 0.78 seconds and produced the coordinates with a 92% success rate.
Dinamika dan Profil Undecided Voters Menjelang Pemilu 2024 di Indonesia
Authors: Priyatno Vincentius Gitiyarko
Published: August 2024

Leading up to the 2024 elections, the public is starting to show their political preferences for both presidential candidates and political parties. However, there is still a portion of the population that hasn't disclosed their choices. Unlike abstaining from voting (golput), this position is more temporary, given that there is still time to consider their options for the upcoming elections. In surveys, this position is indicated by responses such as "don't know," "no answer," or keeping their choice secret when asked about which figure or party they will vote for in the elections. The August 2023 survey by Litbang Kompas indicates that this group is still around 11.6 percent. Considering the 4 percent threshold for a political party to enter parliament, this is a significant number. Additionally, for the presidential choice, 27.9 percent of respondents are still undecided. The research methodology employed in this study is quantitative, using a survey of respondents across Indonesia (N:1364). Data analysis involves descriptive statistical analysis by compiling frequency tables with several cross-tabulations. A comparison with previous survey results is also conducted to show trends. This research also describes the profile of undecided voters in terms of gender, age, education level, and respondent's area of residence for both presidential and political party choices.Menjelang pemilu 2024, masyarakat mulai menunjukkan preferensi politik mereka terhadap pilihan presiden maupun pilihan partai politik. Namun, masih ada sebagian publik yang belum menunjukkan pilihannya. Berbeda dengan golput, posisi ini lebih temporer mengingat masih ada waktu untuk mempertimbangkan pilihan dalam pemilu nantinya. Dalam survei, posisi ini ditunjukkan dengan pilihan jawaban tidak tahu, tidak jawab, atau rahasia saat ditanya tokoh siapa maupun partai apa yang akan dipilih dalam pemilu. Survei Litbang Kompas Agustus 2023 menunjukkan kelompok ini masih sekitar 11,6 persen. Mengingat ambang batas sebuah partai politik masuk ke dalam parlemen adalah 4 persen, maka jumlah tersebut tidaklah sedikit. Ditambah lagi, untuk pilihan presiden, masih ada 27,9 persen responden yang belum menentukan pilihan. Metode penelitian yang digunakan dalam penelitian ini adalah kuantitatif dengan survei terhadap sampel responden di seluruh Indonesia (N=1364).  Sedangkan analisa data menggunakan analisis statistik deskriptif dengan menyusun tabel frekuensi dengan beberapa krostabulasi. Dilakukan juga pembandingan antara hasil survei sebelumnya untuk menunjukkan tren. Penelitian ini juga mendeskripsikan profil undecided voters dari sisi jenis kelamin, usia, tingkat pendidikan, serta wilayah domisili responden baik untuk pilihan presiden maupun partai politik.

Published: August 2024

One form of potential threat faced by Indonesia is an energy crisis that can disrupt national stability. However, the use of nuclear as an alternative source of clean energy through Nuclear Power Plants (PLTN) has not been realized until now. This research aims to identify the obstacles faced in the plan to build a nuclear power plant in Indonesia and explain the communication strategy in facing the rejection of nuclear energy utilization as a power plant in Indonesia. This research uses qualitative methods with data collection techniques through interviews with competent parties in the energy sector, especially nuclear energy and its utilization in power plants in Indonesia. The results showed that public acceptance of the nuclear power plant development plan experienced ups and downs depending on the time and events behind it. In addition, the interpretation of the phrase “considering nuclear as the last resort” in the legislation is also one of the obstacles to the progress of the implementation of nuclear power plant construction. Therefore, the support of all stakeholders is needed for the initiative to revise the laws and regulations that are considered to hinder the construction of nuclear power plants, in addition to building communication with those who reject the development plan through structured and massive persuasive and educational methods.Salah satu bentuk potensi ancaman yang dihadapi Indonesia adalah krisis energi yang dapat mengganggu stabilitas nasional. Namun, pemanfaatan nuklir sebagai alternatif sumber energi bersih melalui Pembangkit Listrik Tenaga Nuklir (PLTN) belum terealisasi hingga saat ini. Penelitian ini bertujuan untuk mengidentifikasi kendala-kendala yang dihadapi dalam rencana pembangunan PLTN di Indonesia dan menjelaskan strategi komunikasi dalam menghadapi penolakan pemanfaatan energi nuklir sebagai pembangkit listrik di Indonesia. Penelitian ini menggunakan metode kualitatif dengan teknik pengumpulan data melalui wawancara dengan pihak-pihak yang berkompeten di bidang energi, khususnya energi nuklir dan pemanfaatannya pada pembangkit listrik di Indonesia. Hasil penelitian menunjukkan penerimaan publik terhadap rencana pembangunan PLTN mengalami pasang-surut bergantung waktu dan peristiwa yang melatarinya. Selain itu, interpretasi terhadap frasa “mempertimbangkan nuklir sebagai pilihan terakhir” dalam peraturan perundang-undangan juga menjadi salah satu penghambat kemajuan implementasi pembangunan PLTN. Oleh karena itu, diperlukan dukungan seluruh stakeholder terhadap insiasi untuk merevisi peraturan perundang-undangan yang dinilai menghambat pembangunan PLTN, di samping membangun komunikasi terhadap pihak-pihak yang menolak rencana pembangunan tersebut melalui cara-cara persuasif dan edukasi yang terstruktur serta masif.

Published: August 2024

This literature review critically examines the integration of ethnoscience and technology, highlighting the transformative impact of this amalgamation on the field of social sciences. Ethnoscience, with its focus on understanding the diverse ways in which human communities perceive and interact with their world, and ethnography, a methodology for the immersive study of cultures and social interactions, together provide a robust framework for exploring human cognition, behavior, and societal constructs. The review delves into the key principles of ethnoscience, emphasizing the development and significance of ethnography in anthropological research and the methodological flexibility required to address contemporary challenges. This study further explores the integration of technological innovations such as wearables, digital traces, and information and communication technology (ICT) into ethnographic studies, underscoring the opportunities and challenges presented by the digital era. The paper argues that the incorporation of technology not only expands the methodological toolkit available to researchers but also enhances the depth and breadth of ethnographic insights into socio-economic, policy, and environmental factors influencing technology adoption across various sectors. Despite the methodological, socio-economic, and infrastructural hurdles, the integration offers unprecedented opportunities for understanding complex social phenomena, contributing significantly to policy-making, community development, and technological innovation. This review underscores the necessity of evolving ethnographic practices to keep pace with technological advancements, fostering a deeper and more nuanced understanding of the intricacies of human life in the digital age.
Nectonema horsehair worms (Nematomorpha) parasitic in the Tanner crab Chionoecetes bairdi, with a note on the relationship between host and parasite phylogeny
Authors: Kakui K
Published: August 2024

Nectonema nematomorphs utilize marine crustacean hosts in their life cycle; 16 decapod and 1 isopod genera have been reported to date as host genera. This study reports the first case of Nectonema parasitic in the Tanner crab Chionoecetes bairdi, adding another known host genus. A single nematomorph juvenile was recovered from the body cavity of each of 2 ovigerous female crabs. A nucleotide sequence for the 18S rRNA gene (1854 bp) was determined from 1 Nectonema individual. The 18S sequence showed Kimura 2-parameter (K2P) distances of 10.0, 2.0, and 1.7% from 18S sequences from Nectonema sp. from an isopod host, N. agile, and N. munidae, respectively. In an 18S-based tree, the unknown species was the sister taxon to a clade comprising N. agile and N. munidae, both of which also utilize decapod hosts. The phylogenetic relationships among the 3 Nectonema species parasitic in decapods were not congruent with the phylogeny of the hosts, not supporting a hypothesis of nematomorph-host co-evolution.
Branch-and-bound trees, integrality gaps and online optimization
Authors:   , Borst Sander Johannes
Published: August 2024

Optimization problems are everywhere: from creating high school timetables to designing computer chips.
Many such problems can be reduced to one single generic type of problem, called a mixed-integer-program (MIP).
For this reason, computer programs known as MIP-solvers that are able to solve such problems can be used to solve a wide variety of other problems.
Hence, MIP-solvers are widely employed in practice, both in industry and academia.
Although there are many different MIP-solvers, they all generally apply the same algorithm: the branch-and-bound algorithm.

We know that the running time of branch-and-bound can be exponential in the worst case, but in practice much lower running times are often observed.
Up untill recently, no good theoretical explanation for this phenomenon was known. In this thesis, we make a step towards resolving this paradox, by doing a theoretical average-case analysis of the branch-and-bound algorithm.

As part of this analysis we show that for several classes of randomly generated problems, the running time of the branch-and-bound algorithm is only polynomial in the problem size.
We also design a new node selection rule for the branch-and-bound algorithm that performs that performs better than previously known rules in the theoretical 'explorable heap'-model.
Furthermore, we provide new results about the online hypergraph matching problem
We also provide an experimental analysis of supplementary techniques for an exact version of the branch-and-bound algorithm.

Preschool children experience a rapid process of physical, motoric, intellectual, emotional, language and social development. One thing that influences development is gadgets. Gadgets are equipped with features such as social media, video, audio, images and games so that children become addicted and become lazy about moving or doing activities. The aim of this research is to determine the effect of gadget use on the development of preschool children at Kemala Bhayangkari 3 Padang Kindergarten. The research uses an Analytical Survey design with a cross sectional approach. Data collection was carried out at Kindergarten Kemala Bhayangkari 3 Padang from 10-24 May 2017 with a sample size of 55 people. The sampling technique is saturated sampling with a questionnaire and KPSP format. Data processing uses the chi-square statistical test. The research results showed that 67.3% of respondents were not normal in using gadgets, 50.9% of respondents had deviant development. The results of the bivariate analysis obtained p-value=0.007, meaning that there is a significant relationship between gadget use and the development of preschool-aged children. The conclusion is that there is a significant relationship between gadget use and the development of preschool children. It is hoped that the school will continue to pay attention to children's development and provide stimulus to achieve appropriate development. For parents to limit their children's use of gadgets to 30 minutes a week.

The sedimentary environment and organic matter (OM) accumulation are vital indicators for shale gas exploration. However, research on deep shale gas systems is relatively limited; moreover, the exploration of deep shale gas in the southeastern Sichuan Basin has entered a period of stagnation. In this study, systematic geochemical analysis of Wufeng (WF) and the first member of the Longmaxi (Long-1) deep shale samples from the recently drilled DY7 well in the Dingshan area of the Sichuan Basin is carried out, and the longitudinal variations in major and trace elements are revealed. The differences in the WF, lower section of the Long-1 (Long-11) and upper section of the Long-1 (Long-12) shales are studied in terms of redox conditions, paleoproductivity, terrigenous detrital input, sedimentation rate and paleoclimate, and the different main controlling factors of OM accumulation for these three layers are discussed. The WF shale has a higher TOC content (mean: 5.73%), the Long-11 shale has a high TOC content (mean: 2.89%), while the Long-12 shale has a low TOC content (mean: 1.44%). For the WF shale, due to complex geological events and large fluctuations in element contents, its TOC content is poorly correlated with these indices, redox and paleoproductivity proxies have a positive association with the Long-11 shale’s TOC content, but negatively correlated with terrigenous input and sedimentation rate indices. The formation of these two sets of organic-rich shales (TOC > 2%) is jointly controlled by good preservation conditions. In contrast, the TOC content of the WF shale is higher than that of the Long-11 shale as the result that terrigenous input and sedimentation rate of the Long-11 shale represent the dilution and destruction of OM, which is different from the former. During the Long-12 depositional period, the water column experienced weak reducing conditions and low productivity, and its high terrigenous debris input further diluted the OM, leading to a low TOC content.
