How Does Industrial Agglomeration Affect Exports? Evidence from Chinese Province-Industry Panel Data
Authors: Pan Kang , Liu Rong , Chen Xiaowei , Huang Ying
Published: June 2023

Industrial agglomeration is currently an important mode of industrial organisation in China’s regional economic development. Many provinces rely on their favourable resource and location advantages to formulate corresponding industrial agglomeration policies. Industrial agglomeration policies produce agglomeration effects, which enable enterprises in the agglomeration area to gain external advantages such as labour, resources and technology, effectively improving productivity and promoting sustainable local economic development. Based on the inter-provincial industry panel data from 2008 to 2017, the static benchmark regression model and dynamic GMM model are constructed to study the relationship between industrial agglomeration, labour productivity and exports, and to explore their interaction mechanism and practical effects. The study shows that, firstly, industrial agglomeration in China significantly contributes to industrial exports. However, in the long run, industrial agglomeration has a positive and then negative effect on industrial exports, with an inverted U-shaped curve. Secondly, the relationship between industrial agglomeration and industrial exports is negatively influenced by labour productivity. Finally, based on the perspective of regional heterogeneity, the impact of industrial agglomeration on exports is not significant in industrial base regions, but shows a significant promotion relationship in non-industrial base regions. Moreover, the impact of industrial agglomeration on industrial exports is not significantly different between coastal port regions and non-coastal port regions. Based on the research results, this paper puts forward targeted policy recommendations such as changing the competition model, increasing the introduction of talent and adjusting the industrial structure.

What does contemporary Indigenous stewardship look like in urban spaces? We answer this question by exploring Urban ʻĀina, a practice-based Native Hawaiian paradigm that shapes how we engage urban landscapes as Indigenous spaces, revitalizes the expression of Indigenous knowledge, and relies on Indigenous sensibilities to address and respond to modern issues such as food security, ecological degradation, and the climate change crisis. We find that places shaped by Urban ʻĀina practices serve as cultural kīpuka—biocultural refugia where kincentric, reciprocal relationships are honored through the engagement of ancestral knowledge. In Hawaiʻi, efforts to maintain these kincentric relationships continue to be challenged by political, socioeconomic, environmental, psychological, and spiritual disruptions that have their origin in the illegal overthrow of the Hawaiian Kingdom. Our research methodology and the paper’s resulting structure rely on ceremony and the Pewa Framework, which were selected to transport you through our restoration process. This exploration and the sharing of innovative case studies from urban Oʻahu bring breath and the healing power of Indigenous knowledge and ancestral practices to urban spaces, with the aim of transforming contemporary conceptions of urban stewardship. Through our process, we demonstrate how revitalized ancestral practices foster ecological sustainability, restorative justice, biocultural continuity, food sovereignty, regenerative forestry, and community wellbeing in urban spaces.

The SARS-CoV-2 pandemic demonstrated the need for potent and broad-spectrum vaccines. This study reports the development and testing of a lumpy skin disease virus (LSDV)-vectored vaccine against SARS-CoV-2, utilizing stabilized spike and conserved nucleocapsid proteins as antigens to develop robust immunogenicity. Construction of the vaccine (LSDV-SARS2-S,N) was confirmed by polymerase chain reaction (PCR) amplification and sequencing. In vitro characterization confirmed that cells infected with LSDV-SARS2-S,N expressed SARS-CoV-2 spike and nucleocapsid protein. In BALB/c mice, the vaccine elicited high magnitude IFN-γ ELISpot responses (spike: 2808 SFU/106 splenocytes) and neutralizing antibodies (ID50 = 6552). Testing in hamsters, which emulate human COVID-19 disease progression, showed the development of high titers of neutralizing antibodies against the Wuhan and Delta SARS-CoV-2 variants (Wuhan ID50 = 2905; Delta ID50 = 4648). Additionally, hamsters vaccinated with LSDV-SARS2-S,N displayed significantly less weight loss, lung damage, and reduced viral RNA copies following SARS-CoV-2 infection with the Delta variant as compared to controls, demonstrating protection against disease. These data demonstrate that LSDV-vectored vaccines display promise as an effective SARS-CoV-2 vaccine and as a potential vaccine platform for communicable diseases in humans and animals. Further efficacy testing and immune response analysis, particularly in non-human primates, are warranted.

Published: June 2023

The development of dentition in dogs has been associated with several problems including tooth over-crowding, missing permanent dentition, and persistent deciduous teeth (PDT). Information on dentition development in different breeds is lacking. This study of 61 Yorkshire terriers aimed to determine the (i) average age at deciduous tooth exfoliation, (ii) average age at permanent tooth eruption, (iii) PDT incidence, and influencing factors such as body weight. The ages of exfoliation of deciduous teeth and eruption of permanent dentition were influenced by body weight and tooth type. These dentition changes tended to occur later in dogs ≤ 3 kg versus dogs > 5 kg. Generally, incisors were exfoliated first, followed by premolars and then canines. At a body weight of 4.5 kg, the middle of the data range, the estimated age at loss of deciduous teeth (with 95% confidence intervals) was 21.9 (21.1, 22.9) weeks for incisors, 26.1 (24.9, 27.4) weeks for canines, and 23.9 (22.9, 24.9) weeks for premolar. The estimated age at eruption of permanent dentition was 22.3 (21.6, 23.0) weeks for incisors, 23.8 (23.0, 24.6) weeks for canines, 24.7 (24.0, 25.5) weeks for premolars, and 26.4 (25.5, 27.3) for molar teeth. However, this sequence was disrupted in dogs ≤ 3 kg. Yorkshire terriers had a high incidence of PDT. At a body weight of 4.5 kg, the estimated proportion of PDT was: incisors 0.86% (0.32, 2.31), canines 15.62% (7.62, 29.37) and premolars 3.57% (1.62, 7.66). Canines constituted the most frequently retained tooth type, with 89.1% retained in dogs ≤ 3 kg compared to 12.0% in dogs > 5 kg. This information will enable veterinarians to provide personalised advice regarding the oral care requirements for Yorkshire terriers and highlights the need to regularly monitor this breed between the ages of two and seven months, during the active phases of tooth development.

Published: June 2023

The goal of this study is to evaluate the performance of the National Water Model (NWM) in time and space across the contiguous United States. Retrospective streamflow simulations were compared to records from 3260 USGS gauging stations, considering both regulated and natural flow conditions. Statistical metrics, including Kling–Gupta efficiency, Percent Bias, Pearson Correlation Coefficient, Root Mean Squared Error, and Normalized Root Mean Squared Error, were employed to assess the agreement between observed and simulated streamflow. A comparison of historical trends in daily flow data between the model and observed streamflow provided additional insight into the utility of retrospective NWM datasets. Our findings demonstrate a superior agreement between the simulated and observed streamflow for natural flow in comparison to regulated flow. The most favorable agreement between the NWM estimates and observed data was achieved in humid regions during the winter season, whereas a reduced degree of agreement was observed in the Great Plains region. Enhancements to model performance for regulated flow are necessary, and bias correction is crucial for utilizing the NWM retrospective streamflow dataset. The study concludes that the model-agnostic NextGen NWM framework, which accounts for regional performance of the utilized model, could be more suitable for continental-scale hydrologic prediction.
Water Erosion and Extension of Ground Fissures in Weihe Basin Based on DEM-CFD Coupled Modeling
Authors: Wang Fujiang , Wang Feiyong , Gong Xulong , Zhang Yan , Li Guoqing
Published: June 2023

The Weihe Basin is one of the regions with the highest concentrations of ground fissure development and the most serious disasters in China. Hidden ground fissures are formed in the shallow soil layer due to preexisting fissures generated by tectonism, hidden ground fissures suddenly exposed to the surface after heavy rainfall. Because the details of the water erosion process cannot be replicated by geological survey methods, the erosion and extension mechanism has not fully developed and the discontinuous medium numerical simulation method is well suited for simulating large deformations and facilitates a microscopic perspective in elucidating the underlying causal mechanisms. This paper deploys the discrete element method (DEM)–computational fluid dynamics (CFD) fluid–solid coupled method modeling the growth process of hidden fissures containing different soil types (sand and clay) under heavy rainfall, revealing a mechanism for the development of hidden fissures into surface fissures. The findings include: (1) the emergence process of hidden fissures into surface fissures under heavy rainfall can be summarized into four stages: subsurface erosion into hidden holes, traction into arches, collapse into sinkholes, and horizontal extension; (2) the emergence process of clay is slower than that of sand due to the constraint of cohesion; (3) the shape of the bottom seepage point affects the fissure emergence process, which is an important factor in the macroscopic performance of the exposed surface fissures. The intuitive and reproducible DEM-CFD coupled modeling used in this paper possesses important reference value for the study and prevention of water erosion ground fissures.
Learning-Based Model Predictive Control for Autonomous Racing
Authors: Pinho João , Costa Gabriel , Lima Pedro U. , Ayala Botto Miguel
Published: June 2023

In this paper, we present the adaptation of the terminal component learning-based model predictive control (TC-LMPC) architecture for autonomous racing to the Formula Student Driverless (FSD) context. We test the TC-LMPC architecture, a reference-free controller that is able to learn from previous iterations by building an appropriate terminal safe set and terminal cost from collected trajectories and input sequences, in a vehicle simulator dedicated to the FSD competition. One major problem in autonomous racing is the difficulty in obtaining accurate highly nonlinear vehicle models that cover the entire performance envelope. This is more severe as the controller pushes for incrementally more aggressive behavior. To address this problem, we use offline and online measurements and machine learning (ML) techniques for the online adaptation of the vehicle model. We test two sparse Gaussian process regression (GPR) approximations for model learning. The novelty in the model learning segment is the use of a selection method for the initial training dataset that maximizes the information gain criterion. The TC-LMPC with model learning achieves a 5.9 s reduction (3%) in the total 10-lap FSD race time.
Extension's Efforts to Help Kids Be SAFE: Evaluation of a Statewide Bullying Prevention Program
Authors: Duke Adrienne , Norton Jessica
Published: June 2023

The evaluation reported in this article examined the effectiveness of a statewide bullying prevention program, Be SAFE. Be SAFE involves use of a positive youth development approach to influence peer groups rather than individual bullies or victims. Through the use of pre- and postprogram questionnaires, we found increases in youths' knowledge of how to help someone being bullied and how to be an ally. We found that grade level was associated with youths' knowledge gains across the lessons. The findings from the evaluation can be important for those interested in understanding the impacts of Be SAFE or applying bullying prevention efforts in general.
Nutrient Record Keeping . . . Yep, We've Got an App for That!
Authors: Barker John
Published: June 2023

Technological advances continue to shape agriculture. Many farmers are now using mobile devices to manage their businesses and farming operations "from their shirt pockets." Concurrently, new regulations in Ohio involve a record-keeping requirement. In certain areas of the state, regulations pertaining to weather data and soil conditions restrict fertilizer and manure applications. To assist farmers in meeting these requirements, a multiagency group developed the Ohio Nutrient Management Record Keeper app. This app is available for iOS, Android, and web-based platforms.
Older Adults' Perceptions of Nutrition as Protective Against Detrimental Effects of Environmental Pollution
Authors: Dunn Kristina , Gaetke Lisa , Stephenson Tammy , Brewer Dawn
Published: June 2023

The aging process makes older adults vulnerable to the detrimental health effects of environmental contaminants. Our study assessed older adults' perceptions regarding diet as protective against environmental contaminants, levels of concern about exposure to environmental contaminants, and interest in learning about protective food-related strategies. A needs assessment to collect such information had not been conducted among older adults. Health fair survey results showed that respondents perceived diet as beneficial against contaminants, were concerned about health implications of exposure, and were interested in learning how to protect health through diet-related strategies. Results suggest that a nutrition-focused curriculum addressing how dietary strategies can help protect against environmental contaminants is needed for Extension professionals.

Authors: Tong Cindy , Schermann Michele , Gonzalez Francisco , Rossbach Jonathan
Published: June 2023

To focus future good agricultural practices (GAP) educational efforts, we surveyed leafy greens growers about their farming practices and measured microbial load on greens. Most survey respondents used potable water without added sanitizer for washing. Pathogenic bacterial levels were undetectable or low on farm and farmers' market samples. Coliform counts were in the normal range and were similar across farms and treatments. The microbial food safety risk from locally grown leafy greens appeared to be low. Therefore, future outreach efforts can focus on worker hygiene and cleanliness of farming operations, making GAP training less onerous for growers.
Perception of Current and Ideal Practices Related to Public Value in Extension
Authors: Anderson Emily , Roop Kelsey , MacArthur Stacey
Published: June 2023

Extension professionals are increasingly encouraged to engage in practices that can advance the public value movement. It is unclear, however, whether recommended practices related to public value are being adopted. In 2014, 235 Extension professionals at Mississippi State University responded to an organizational capacity survey that included questions on public value practices. Research described here explored discrepancies between current and ideal public value practices among Extension professionals. Paired-samples t-tests revealed statistically significant discrepancies between current and ideal public value practices. The findings can inform efforts by Extension professionals seeking to increase awareness and practices related to public value.

The article provides information on a burial in a niche under a stone at Cape Bratyev in Babushkin Bay studied by S. P. Yefimov in 1976. The work yielded anthropological materials and related archaeological finds. The chance to conduct a whole genome analysis of bone remains from this burial stimulated their further study as well as the need to inspect the sites and burial grounds of the specified area. Interesting and significant data on anthropology and genetics were obtained. The individuals from the burial were found to belong to the present-day Koryaks' ancestry. It is also noted that, in the past, the inhabitants of this coast had some population contacts with the ancient residents of the southern Sea of Okhotsk shores. Brief information on the survey of Babushkin Bay archaeological sites is presented, as well.

Published: June 2023

Basing on materials collected in April-September 2014-2022 in the intertidal zone of the northeastern part of Avacha Bay, the seasonal dynamics of the size-age structure of stone cockscomb Alectrias alectrolophus living here was analyzed. It has been established that in April through late June this species is represented in the littoral by individuals in the second year of life (1+) (body length 35-67 mm, body weight 0.19-1.37 g) as well as by individuals aged 2+ to 7 years (64-143 mm, 1.09-15.9 g, respectively), which form two rather well-separated size groups of fish. In August, as the size of individuals in the second year of life (1+) increases, these groups merge, forming a single bimodal curve of size composition. In the second half of June, underyearlings of the stone cockscomb, 16-20 mm long with a body weight of 20-30 mg, begin to appear in the intertidal zone, forming the third size group from 20 to 35 mm with a body weight of 40-230 mg in July. Therefore, starting from July, in the intertidal zone of Avacha Bay, the stone cockscomb of all age groups, from underyearlings to individuals 7+ years old, lives. Data on seasonal changes in the ratio of juveniles and adult fish in the intertidal zone are presented.

Detailed surveys were performed with accurate fixation of the seabird's colonies locations on never researched sections of the coast next to the city of Magadan. The population was counted, the changes in the condition of the largest seabird colonies near the city, subjected to maximum anthropogenic pressure, were analyzed. The colonies under research included those on the Three Brothers Islands, on Isle Monakh (Kekurny), on Cape Ostrovnoy, and on island bars in the Ola and Arman lagoons. The total number of breeding seabirds, according to the latest counts in this area, including the abovementioned islands and lagoons, amounted to 88.7 thousand individuals. The first, in the history of observations, decrease in the number of seabirds in the Three Brothers colonies from 33.6 thousand to 28.9 thousand individuals in 5 years might be associated with the closure of the urban untreated sewage discharge into Gertner Bay. Monospecies colonies of the Slaty-backed Gull on the island bars in both lagoons, despite the strong anthropogenic pressure and the dynamic change in the islands contours, are still growing steadily and rapidly. In the Ola Lagoon, the number of nesting gulls has increased from 14.2 thousand to 37.6 thousand individuals over the past 9 years; in the Arman Lagoon, from 1.4 thousand to 4.2 thousand individuals within 5 years; their further growth can be predicted. At the present, the Slaty-backed Gull colonies in the Ola Lagoon are the largest in Tauysk Bay.
Providing distributed system integrity under spatial grasp technology
Authors:   Institute of Mathematical Machines and Systems Problems of the National Academy of Sciences of Ukraine, Sapaty P.S.
Published: June 2023

In the last decades, we have witnessed an exploding growth of different kinds of sophisticated distributed systems with financial, industrial, ecological, security, military, and many other ap-plications. Providing high integrity of such systems is becoming a key point of their develop-ment, evolution, and usage, especially in various crisis situations and under disastrous and ad-versarial conditions. The paper reviews a number of existing works on the integrity, security, and recovery of distributed systems. It also briefs the main aspects of the Spatial Grasp Model and Technology (SGT), reflecting some general issues of the paradigm, its Spatial Grasp Lan-guage (SGL), and networked SGL interpretation in distributed environments. SGT can dynami-cally establish and keep superior power over large distributed systems, including creating them from scratch. Using a graph-based representation of the distributed system topologies, with nodes having both virtual and physical properties, the paper shows full topology creation start-ing from all nodes in parallel and then from a single node, also copying the existing topology in similar cases. In addition, it demonstrates how to organize distributed systems in such a way so that they can self-recover in any circumstances and after any damages by supplying their nodes with universal genetic-like capabilities by which any self-repairs can be organized. Such recovery may be from missing neighboring nodes and links to the rebuilding of the distributed topologies, which means they cannot be destroyed even in the severest conditions. These features can be particularly useful after IT network damages, environmental and industrial disasters, for crisis management, and on battlefields. The paper confirms the efficiency of the developed distributed control approach for providing high integrity and self-recovery of im-portant distributed systems.

Published: June 2023

One of the possible ways to improve the quality of operational management of counteracting emergency situations by means of situation centers is the use of appropriate decision support systems. As such a decision support system, the article examines the DSS SPOR which provides solutions to the problems of operational management of countermeasures against emergencies with the help of electronic action plans. The article describes the first part of the methodologi-cal bases of creating electronic action plans, the purpose of which is to consider the general the-oretical problems of structuring the process of countering an emergency situation, independent of the specifics of a specific emergency, aimed at substantiating of the general methods of cre-ating of electronic action plans. In order to avoid possible disagreements in the interpretation of the main concepts used in the presentation of methodological bases, their definitions are pro-vided. The purpose and structure of the methodological bases are substantiated and the main actions that underlie the development of an electronic action plan are characterized. The re-quirements for an emergency situation, to meet which it is expedient to use DSS SPOR, have been determined. General methodological bases for the development of electronic action plans are outlined as well. The features of forming a set of operations that form ordered sequences that will make up an electronic action plan are described. The problem of updating the content of the initial data when adapting a typical electronic action plan is characterized and the re-quirements for the initial data of operations necessary for the creation of an electronic action plan are formulated. The peculiarities of the use of the obtained results in the creation of elec-tronic action plans will be presented in the second part of the methodological bases.
The development of the RBA paradigm based on the theoretical research in the field of safety
Authors:   Institute of Mathematical Machines and Systems Problems of the National Academy of Sciences of Ukraine, Begun V.V.
Published: June 2023

The paper considers the introduction and development of the risk-based approach (RBA) para-digm. It describes the capabilities of RBA methods to categorize threats by their level of dan-ger, which allows the use of information technologies and the implementation of more efficient optimization measures. A gradual transition to the RBA paradigm from the point of view of IT development and as a way to the independent (impartial) audit of the main safety parameters has been traced. The possibilities and limitations of the existing methods are analyzed, and the trend toward the transition to adaptive security management is shown in the paper. The possibil-ities of reducing the costs of building models for determining the numerical values of risk due to the development of probabilistic structural and logical models by types of dangerous objects and productions are demonstrated. The significant potential of domestic developments concern-ing the development and implementation of a probabilistic-physical approach to the assessment of durability and reliability using probabilistic models based on DM- and DN-distribution func-tions in conditions of insufficient information on failures is described in the article. The work demonstrates the effectiveness of the transition to the modern methods of safety analysis based on the RBA paradigm in Ukraine's nuclear energy sector since the early 2000s. In this sector, thanks to the updating of development processes, safety planning measures, and government control, the damages resulting from emergency shutdowns have decreased by more than 10 times. At the same time, it has been noted that our country is lagging behind in implementing the RBA paradigm in other areas of production and life. To accelerate the implementation of RBA in a wide range of industries and spheres of life, the priority problems and tasks related to the development of IT, which require solutions in our country and all over the world, have been formulated.
Implementation of the elements of the enterprise protection system
Authors:   State University of Trade and Economics, Yurchenko Yu.Yu.
Published: June 2023

The article defines the main tasks and features of corporate information networks and analyzes the specifics of the corporate network implemented in a medical center. The proposed data protection system at the enterprise is developed on the basis of the Bella-La Padula model since the key provisions of this model are the assignment of special security levels to all participants in the protected data processing process and to the documents in which it is contained. The specified security levels are arranged using the established dominance relationship, and the access control is carried out depending on the security levels of the interacting parties, which allows the application of technical solutions of the Active Directory service. One of the elements to ensure data protection is the use of a Shadow Copy of data according to the appropriate schedule. An important component of ensuring data protection is the individual process of setting up group policies and checking replication with other servers running the Active Directory directory services of the medical center. As a result of the implementation of elements of the company's data protection system, it was possible to significantly increase the level of protection and set up a backup server, on which appropriate folders were created, to which backup copies would be made according to the schedule. This function makes it possible to save the history of changes in any file for a certain period. The proposed elements of the security system can be used to analyze the security system, control access, ensure data integrity, etc. The Active Directory directory services were implemented in the medical center, and data replication to a backup server was configured. Taking into account the specifics of the enterprise, namely the medical center, the implemented elements of the data protection system ensure the delimitation of access levels, implement protection profiles and secure the personal data of patients.

Published: June 2023

The article is devoted to solving the problem of determining the residual resource of pipelines. Erosion and corrosion damage was selected as the main negative factor that is being investigat-ed and affects the service life. In particular, it is the erosion-corrosion damage of the “pitting corrosion” type which is one of the most serious and widespread types of corrosion that can cause a significant shortening of the service life of technical objects and an increase in the cost of their maintenance, repair, and replacement. The residual thickness of the pipeline wall was chosen as the defining parameter. In case there are no significant failure statistics, a probabilis-tic-physical approach is used to assess the objective technical condition and predict the residual resource of the specified structures. The approach to durability assessment is based on a proba-bilistic model and uses the DM failure distribution that is specially formalized on the basis of a Markov random process of the diffusion type with a constant rate. The DM distribution most accurately aligns statistical data on failures of mechanical objects, which are pipelines for vari-ous purposes. It is very valuable that the parameters of the used model are based on a physical interpretation, which allows for estimating the parameters of the model when there are no fail-ure statistics. The analysis is based on two key parameters: the average rate of change of the defining parameter change (the performance criterion) and the coefficient of variation of the generalized degradation process. The paper provides an example in which the residual resource of a pipeline section is determined with the help of the probabilistic-physical method. The re-sults obtained during the calculations are compared with the results obtained by another tradi-tional method. Refining the assessment of the residual resource of the pipeline section will al-low for optimizing the operating costs by reducing the intervals between repairs.

This study aimed to provide input and evaluation for the Surakarta City Communication, Information, Statistics, and Encryption Service in measuring the effectiveness of their information dissemination work programs. Conducted as a descriptive quantitative research with a sample size of N = 30, the study assessed the media consumption patterns of Surakarta City residents and the affordability of the promotional media used by the Solo City Government. The findings of this study revealed that the magazine "Solo Berseri" possesses sufficient attractiveness and informational value, meeting the gratification needs of its readers. However, the limited accessibility of this magazine hampers its effectiveness as a promotional medium.
These results emphasize the importance of ensuring accessibility and distribution channels for promotional materials. Addressing the limited accessibility of "Solo Berseri" would enhance its impact as a promotional medium for the Solo City Government. Additionally, the findings suggest that the strategic placement of billboards can effectively reach the target audience and disseminate important information. Based on these findings, recommendations can be made for the Surakarta City Communication, Information, Statistics, and Encryption Service to improve their information dissemination strategies. Implementing measures to increase the accessibility of "Solo Berseri" and exploring additional affordable promotional media channels could enhance the effectiveness of their communication efforts. By incorporating these suggestions, the Surakarta City Government can enhance their communication efforts and ensure that important information reaches and resonates with the residents effectively

During this training and acclimatization period, they experienced the hardships of trench warfare and their first combat and casualties of the war. Yet, most World War I histories omit the preparatory experiences of the 4th Brigade of U.S. Marines at Toulon and the valuable lessons this training period conferred, an oversight which this article seeks to begin to correct.
“To Take Some of That Fear Away”: Task Cohesion and Combat Effectiveness Among Combined Action Platoons in Vietnam, 1965–71
Authors: Sutton Cavender S.
Published: June 2023

Marine Combined Action Platoons (CAP) during the Vietnam War offer a unique lens through which to explore what makes a body of disparate individuals unify into an effective fighting force. How did small units with virtually no supervision coalesce into cohesive and lethal military organizations, and how did they maintain focus on helping villagers while repeatedly battling irregular enemy forces, most of whom were indistinguishable from the local populace? This article posits that living among the South Vietnamese and fighting at the village level fostered a personal attachment to the war that did not exist among American servicemembers elsewhere. CAP Marines maintained higher levels of task cohesion than their non-CAP counterparts, ensuring that they often remained effective fighting forces until the program’s termination in 1971.

Angka kematian ibu (AKI) sebagai salah satu indikator kesehatan

ibu, dewasa ini masih tinggi di Indonesia. Berdasarkan perhitungan

BPS (Badan Pusat Statistik) AKI di Indonesia tahun 2021 adalah

248/100.000 kelahiran hidup, dan Angka Kematian Bayi (AKB)

adalah 26,9/1.000 kelahiran hidup. Faktor – faktor yang

mempengaruhi masih tingginya AKI di Indonesia antara lain

pengawasan kehamilan belum menjangkau masyarakat secara

menyeluruh dan bermutu, pertolongan ibu hamil dan persalinan

yang belum memadai dan lemahnya sistem rujukan dan pendidikan

serta pengetahuan masyarakat yang rendah tentang tanda-tanda

bahaya kehamilan. Tujuan penelitian untuk mengetahui pengaruh

pendidikan kesehatan terhadap tingkat pengetahuan ibu hamil

trimester 1 tentang adapatsi kehamilan. Penelitian ini merupakan

penelitian kuantitatif desain quasi eksperimental dengan one

group pre-test dan post-test. Populasi dalam penelitian ini semua

ibu hamil trimester I yang berjumlah 40 ibu hamil trimester I di

Puskesmas Sukajadi. Hasil penelitian diperoleh nilai p (0,000)

α=0,05 maka dapat disimpulkan bahwa terdapat pengaruh

pendidikan kesehatan terhadap tingkat pengetahuan ibu hamil

timester 1 tentang

adaptasi kehamilan sebelum dilakukan

pendidikan kesehatan dan setelah dilakukan pendidikan kesehatan.

Melalui pendidikan kesehatan tujuan kebidanan dapat dicapai

dengan indikator ibu yang menyatakan lebih siap menghadapi

kehamilan karena telah memahami perubahan apa yang sebenarnya

Kehamilan menyebabkan perubahan fisiologis pada ibu hamil

antaranya di rongga mulut. Perubahan di rongga mulut

dipengaruhi oleh sistem hormonal karena peningkatan

hormon estrogen dan progesterone bersamaan dengan faktor

iritasi lokal di dalam rongga mulut sering terjadi pada ibu

hamil yaitu gigi berlubang penyebabnya yaitu kurangnya

perawatan gigi dan mulut. Tujuan penelitian untuk melihat

hubungan pengetahuan sumber informasi dan perilaku pada

ibu hamil dengan kesehatan gigi dan mulut selama kehamilan

di Puskesmas Pangkalan Balai Kabupaten Banyuasin III.

Penelitian ini menggunakan metode survey analitik dengan

pendekatan survey cross sectional. Populasinya seluruh ibu

hamil yang berkunjung di Puskesmas pangakalan Balai, dan

sebanyak 34 orang sampel yang diambil dengan teknik non

probability berupa accidental sampling. Penelitian ini

menggunakan instrument berupa kuesioner kesehatan dan

gigi dan mulut dan pemeriksaan OHI-S (Simplified Oral

Hygiene Index). Hasil analisis univariat dan bivariat

didapatkan responden kesehatan gigi dan mulut baik

sebanyak 19 responden (55.9%). Responden dengan

pengetahuan baik sebanyak 21 responden (61.8%),

Responden dengan sumber informasi baik sebanyak 16

responden (47.1%). Serta responden dengan perilaku baik

sebanyak 21 responden (61.8%). Dari uji Chi Square ada

hubungan yang bermakna antara Pengetahuan dengan

kesehatan gigi dan mulut dengan p-value=0,021. Terdapat

hubungan perilaku antara kesehatan gigi dan mulut p-

value=0,049. Serta tidak terdapat hubungan antara sumber

informasi dengan kesehatan gigi dan mulut p-value=0,28.

Hybrid approach for adaptive fuzzy grid partitioning and rule generation using rough set theory
Authors: Zheng Pa Liu , Zhang Liu Wang , Cheng Li Wang , Huang Koscik Xue
Published: June 2023

This research proposes a hybrid approach for adaptive fuzzy grid partitioning and rule generation using rough set theory to address the problem of customer segmentation based on purchasing behavior. The objective is to minimize the fuzziness of the partitioning while maximizing the accuracy and interpretability of the generated rules. The research utilizes a dataset consisting of customer transactions, including demographics, purchase details, and satisfaction ratings. The fuzzy grid partitioning process divides the customer space into grid cells, representing different segments. Fuzzy membership values are assigned to data points based on their association with each grid cell. Rough set theory is employed for attribute reduction, identifying the most relevant attributes for customer segmentation. Rule induction algorithms generate rules that capture the patterns and dependencies among customer attributes and their association with specific grid cells. The hybrid approach combines the advantages of adaptive fuzzy grid partitioning and rough set-based rule generation. The optimization process adjusts fuzzy membership values and refines the generated rules to improve accuracy and interpretability. A numerical example and a case study in the retail industry are presented to demonstrate the effectiveness of the proposed approach. Results show successful customer segmentation and generation of actionable rules for marketing strategies. The research contributes to the field of customer segmentation by providing a comprehensive methodology that integrates adaptive fuzzy grid partitioning and rule generation using rough set theory. The hybrid approach offers valuable insights into customer behavior, enabling targeted marketing campaigns, personalized recommendations, and enhanced customer satisfaction.
INTEGRATING IEEE 802.11 AND LORAWAN FOR WIRELESS SENSOR NETWORK DATA TRANSACTION IN NON-INFRASTRUCTURE AREA

Published: June 2023

This research aims to develop a system that integrates the IEEE 802.11 network and LoRa WAN in developing a wireless sensor network (WSN) in an area without public communication infrastructure. The sensor nodes were developed using ESP 8266 Node MCU with embedded IEEE 802.11 module and the sink was developed using Raspberry Pi minicomputer with LoRa module. The frames sent by sensor nodes were classified into regular data and critical data. The sensing data is forwarded by the sink to the nearest location with internet access using LoRaWAN according to their priority. Each node sent its regular frames with an interarrival time that varies from 30 seconds to 3 minutes and critical frames with an interarrival time of 1 to 5 seconds. The result shows that the delay of the network sending solely regular frames varies from 16.4 s to 602  and the delay of the network sending solely critical frames varies from 0.32 t0 1 s. When some nodes in the network send the regular frames and the other nodes send the critical frames, the delay of the regular frames drops to 1.25-1.75 s. The packet delivery rate of the system is 100%.
