Authors: J Yu , S Zhao , H Yu , Y Jia , L Xu , F* Yang
Published: December 2024

Objective: To establish a nomogram model for predicting the overall survival (OS) of esophageal squamous cell carcinoma
(ESCC) patients with lymph nodes metastasis (LNM) who had surgery.
Methods: ESCC patients with LNM who received surgery from 2004 to 2015 in the Surveillance, Epidemiology, and Final
Results (SEER) database were selected. The whole cohort (n=468) was randomly divided into training (n=328) and validation
group(n=140). The Cox regression models were applied to identify the related prognostic factors for the nomogram. The
performance of the nomogram was evaluated by Harrell’s concordance index (C-index), the area under the time-dependent
receiver operating characteristics curve (AUC), the net reclassification improvement (NRI), integrated discrimination
improvement (IDI), decision curve analysis (DCA), and calibration curve.
Results: Surgery prime site, T status, M status, radiation sequence with surgery, age, race, and gender were incorporated in
the nomogram. The better discrimination performance, more accurate prediction, and superior clinical usage of nomogram
can be observed according to C-index, AUC, NRI, IDI, and DCA when compared to the traditional staging system in both cohorts.
The excellent consistency was shown from calibration plots in 2 cohorts.
Conclusion: The nomogram was developed and validated to predict OS for targeted ESCC patients.

The risk of fatigue and accidents is prone to occur in the process of harvesting coconuts by climbing due to the height of coconut trees. Coconuts that fall directly without any fishing gear or bedding will immediately collide with the ground, potentially causing damage  in  the  form  of  bruises  and  ruptures  to  the  decline  in the quality of young coconuts.  The  purpose  of  this  activity  is  to  design  and  test  anti-shattering  and non-climbing  young  coconut  harvesting  equipment  based  on  telescopic  sticks  and portable trolley systems. Telescopic sticks are used as a system to adjust the height of telescopic sticks to the height of coconut trees equipped with elbow clamps, telescopic sticks, and electric saws. Electric saws are used as a tool to cut young coconut bunches using a 1CH remote wireless relay switch. Portable trolley is used as a reservoir and impact absorber for falling young coconuts that can be adjusted in height. This tool is designed to transport more than 100 kg of young coconuts or the equivalent of 10-15 bunches of young coconuts. In addition, this tool is also used to facilitate mobilization to the Results Collection Point (TPH). The test results show that this tool performs well with a working capacity of 810 kg/h, 2.7 times greater than the manual capacity with low work risk. In connection with that, it was found that the basic cost of this tool was Rp103,589/ton while conventionally it was Rp276,473/ton. Keywords: No Climbing, Portable Trolley, Shatterproof, Telescopic Sticks, Young Coconut.

Expression of calibration and measurement capabilities of accredited calibration laboratories in a measurement range
Authors: Zakharov Igor , Novoselov Oleg , Botsiura Olesia
Published: December 2024

The expression of calibration and measurement capabilities (CMCs) of accredited calibration laboratories in a range of values is analysed, and the insurance of appropriate linear interpolation to find the measurement uncertainty at average values is considered.
To minimize the expanded measurement uncertainty, it is proposed to calculate the coverage factor using the kurtosis method so that it would correspond to the composition of the distribution laws of the input quantities.
To approximate the laboratory calibration and measurement capabilities when expressing them as an explicit function of the measurand, it is proposed to apply the least squares method. For non-polynomial dependencies, the capabilities shall be first transformed by replacing the variables into linear ones, which shall be followed by using the least squares method. To facilitate the approximation of CMCs, the use of the “trend line” function of MS Excel is proposed. Four additional nonlinear functions are considered, which are approximated by hyperbolic and homographic functions of Types 1 and 2, as well as by quadrature addition, which can also be transformed into a linear function, and the estimates of their parameters can be obtained by using the least squares method.
An example of performing the approximation by various functions of calibration and measuring capabilities of a laboratory when calibrating a digital caliper is considered.
Metrics of non-visual effects of light

Published: December 2024

The discovery of a new photoreceptor ipRGC (melanopsin) and the associated non-visual impact of the lighting environment on human well-being and health has led to a significant amount of research in the field of the connection between the parameters of light sources and human biological activity. The results of studying the non-visual effect of light are successfully applied in circadian lighting, which is based on changing the correlated colour temperature (CCT) of light sources of indoor lighting system during the day in accordance with the natural change of this parameter, and contribute to maintaining the biological processes of vigilance and preparation for sleep.
However, the study of the light sources parameters for indoor lighting that can affect human well-being is not limited only to their CCT. After more detailed study of the radiation spectrum influence on the concentration and dynamics of melanopsin, the International Commission on Illumination (CIE) has proposed an algorithm for determining the melanopic irradiance and melanopic illuminance precisely by the spectral distribution of irradiation sources.
To quantify the ratio of the non-visual impact of the lighting environment parameters on human well-being, the ratio of the melanopic flux M to the photopic luminous flux P for a test light source, which is a dimensionless quantity, can be used as a new ratio M/P. By definition, this ratio is normalized to 1 for the reference daylight illuminant D65. This ratio can be applied for creating a new lighting metric that can characterize LED light sources in terms of its potential for non-visual impact depending on its spectral characteristics. Moreover, new metrics of non-visual light impact will be helpful for the implementation of integrative lighting principles declared by the CIE as balance between human well-being, health, and functioning lighting for achieving the energy savings and reducing the impact on environment by applying LED systems with the considered characteristics.
Design of Physics Learning Module Integrated with Problem Based Learning Model on Renewable Energy Material Class X MA
Authors: Nindi Syakila  , Hidayati Hidayati
Published: December 2024

Independent Curriculum provides flexibility to schools and teachers in designing learning. However, this flexibility causes differences in the allocation of learning time in some schools. In physics subjects, some Madrasah Aliyah have less time allocation per week compared to other schools, this causes students to need to be trained to learn independently. Meanwhile, Phase E physics learning outcomes require students to play an active role in providing problem solving. Therefore, a learning module integrated with the Problem-Based Learning (PBL) model is needed to support independent learning and train students' problem-solving skills. This study aims to produce a physics learning module integrated with a valid PBL model on renewable energy material for class X Madrasah Aliyah. This research uses the Research and Development (R&D) method with the 4D development model, which includes defining, designing, developing, and disseminating stages. The module validation results showed a value of 0.92 with a very valid category. This shows that the developed module has met the validity criteria and is suitable for use. The implication of this research is that the module can help students learn independently and train students to solve problems.
Possibilities of laser polarimetric diagnostics of umbilical blood and capillary maternal blood
Authors: Antonuyk Olha , Ushenko Alexandr
Published: December 2024

A comparative analysis of the two types of samples showed differences in values of the statistical moments of the 3rd and 4th orders. In particular, the statistical moment of the 3rd order (asymmetry) is 2.5 times greater and the 4th parameter (kurtosis) is 2.5 times greater for the blood samples of newborns without pathological changes than the similar parameter for the blood samples of newborns with pathological changes. Fractal analysis showed the transformation of the distribution of power spectra from fractal for coordinate distributions of the Muller matrix element for blood samples without pathology to multifractal (fractal dimensions D1=1.66, D2= 2.90 and D3= 0.56) of blood samples with pathology.
The diagnostic sensitivity of the statistical moments of the coordinate distributions of the orientation-phase elements of the Muller p34 matrix of higher orders (3rd and 4th) to structural changes occurring in blood samples of mothers of newborns with a normal physiological state and with pathological changes was revealed. In particular, with pathological changes, the statistical moments of the third order (asymmetry) decrease by 3.5 times, and accordingly, the statistical moment of the fourth order (kurtosis) increases by 2.5 times. The spread of the values of the statistical moments within the two groups did not exceed 5-10% of corresponding average values. The diagnostic possibilities of statistical and fractal analysis of the coordinate distributions of the elements of the Mueller matrix of blood samples of different physiological states of newborns and their mothers have been demonstrated.
Fractal and statistical analysis of the coordinate distributions of the orientational elements of the Mueller matrix p33 are diagnostically sensitive when examining the blood of newborns. For maternal blood samples, the statistical analysis of the orientational-phase elements of the Muller p34 matrix (increase in the statistical moments of the 3rd and 4th orders with pathological changes) is diagnostically sensitive.

Published: December 2024

Social forestry is envisioned as a governance reform to empower rural communities to improve both the forest condition and their quality of life. In Indonesia, however, its implementation has been plagued by a number of governance-related issues including corrupt practices among various actors. Drawing on programs implemented in Java, we delve into the types and mechanisms by which corruption has occurred (or occurs) in various social forestry activities. Tracking experience across several phases of social forestry, the corrupt practices were initially performed among the field foresters and the higher hierarchies. These corrupt practices were later imitated by other actors, who increasingly considered them as normal and acceptable practices. In contemporary social forestry programs, corruption is conducted by diverse stakeholders, including smallholder farmers, public officials and other authorities among the bureaucracy, as well as non-government organizations. Corruption has significant bearing on policy initiatives and programmatic outcomes, as it inhibits the implementation of formal rules and norms of social forestry. Our historical tracing provides better insights into why corruption is not only a social forestry-related challenge but also a part of a larger societal problem as it has been normalized and deepened over decades.

Published: December 2024

The study employed a qualitative approach to determine the influence and effectiveness of storytelling in shaping the Alpha generation’s buying decisions and consumption behaviours. The students of the University of Lagos Junior Secondary School were selected for the study. The interview questions were set to focus on factors like experiences, sources of storytelling communication, the outcomes and the affective effects. Twenty-five students were purposively selected out of one hundred and twelve (112) population for the interview based on the conditions for selection. Thematic analysis was used and a total of 244 themes were identified. Four (4) major themes were later identified in thematic synthesis through coding translation. The findings revealed that storytelling is effective and strategic in brands targeted at the Alpha generation, hence, the generation relied on storytelling to choose brands in convenience, impulsive and shopping products, and radio and television were the main sources of storytelling campaigns among the generation. Storytelling wrapped in songs, entertainment, dancing, drama, etc. captivated and influenced the generation, and children used the information from the storytelling campaigns to influence family purchase decisions and parents’ buying decisions and behaviours.
Cofree Com-PreLie algebras

Published: December 2024

A Com-PreLie bialgebra is a commutative bialgebra with an extra preLie product satisfying some compatibilities with the product and the coproduct. We here give examples of cofree Com-PreLie bialgebras, including all the ones such that the preLie product is homogeneous of degree $\geq -1$. We also give a graphical description of free unitary Com-PreLie algebras, explicit their canonical bialgebra structure and exhibit with the help of a rigidity theorem certain cofree quotients, including the Connes-Kreimer Hopf algebra of rooted trees. We finally prove that the dual of these bialgebras are also enveloping algebras of preLie algebras, combinatorially described.
Bulb selection of shallot local varieties from true shallot seeds (TSS) for bulb split components
Authors: Nursalma Linda , Maharijaya Awang , Sobir
Published: December 2024

The development of quality shallot seeds from new superior varieties needs to be done because only about 10% of the shallot seed needs are currently covered. However, true shallot seeds (TSS) production from the local varieties, such as the Bima Brebes variety, is still rarely developed and has not been able to produce many split bulbs from TSS. The existence of split bulbs in one plant is preferred by consumers and is beneficial for shallot seedlings. This is related to the number of seeds farmers can use per kilogram of seed obtained. Therefore, this study aimed to select shallots that produce split bulbs from seeds produced from TSS. This research was conducted at Tajur Experimental Farm, Center for Tropical Horticulture Studies IPB University, Bogor. Seedlings were done in beds shaded with transparent plastic that can be opened and closed. The split bulbs produced by the Bima Brebes variety derived from TSS seed sources were still relatively low at 39.69% and significantly different from the comparison varieties at more than 60%. Sanren variety produced split bulbs from TSS seed sources as high as 64.13% and the Maserati variety about 61.25%.

«Амурские волки» – «Тайны Зеи»: эпизод творческого соперничества в литературе Приамурья начала XX века
Authors: Урманов Александр Васильевич
Published: December 2024

One of the consequences of the increasing interest in regional cultural phenomena in modern historical and literary science is the emergence of a number of studies devoted to the most significant writers of the Amur region at the turn of the XIX–XX centuries: L. Volkov, F. Chudakov, A. Matyushensky etc. However, their work is usually considered in isolation, each in its own right, out of connection with other phenomena, in isolation from the general trends in the literary life of the Far East and Russia as a whole. The creation of a holistic picture, a full-fledged history of Russian literature in the Far East is not an immediate prospect. Today's task is to purposefully "launch" this process, including the identification of literary interrelations, various kinds of "dialogues", "interlocutions", "disputes", "couplings", "crossings", "repulsions", which form a living literary process. The purpose of this article is to consider in interrelation two works created at the same time by the brightest writers of the Amur region – A. Matyushensky and F. Chudakov.

Published: December 2024

Globally, the elderly population are more increasing each year. The enhancement of life expectancy is also followed by the enhancement of chronic illness, which one of them is liver disease. In elderly, there are also several physiological and biochemical changes in liver. Several studies show that the reduction of liver function will affect the severity of liver clinical manifestation in older people. This review article aims to discuss more about liver disease in older population. Hepatitis A in elderly has higher mortality and morbidity rates compared to young people. More over, the progressivity of acute hepatitis B to chronic hepatitis B is also greater in older people than young people. The treatments of hepatitis B and hepatitis C are safe and effective to be applied in elderly. Polypharmacy and fraility affects the elderly to be more susceptible to drug induced liver injury (DILI). This review aims to address knowledge gaps in understanding the morphological and functional changes in the aging hepatic system, their implications for disease progression, and the effectiveness of current therapeutic strategies. By critically analyzing recent evidence, we identify challenges in treating liver diseases in the elderly and highlight areas requiring further research.Keywords: Elderly, hepatocellular call carcinoma, liver disease
Peutz-Jeghers Syndrome: A Case Report and Literature Review in Indonesia
Authors: Renaldi Kaka , Friatna Yudha
Published: December 2024

Background: Peutz-Jeghers Syndrome (PJS) is a rare hereditary polyposis syndrome that is autosomal dominant and has the main characteristics of hamartoma polyps, mucocutaneous pigmentation, and increased susceptibility to malignancy. Case: This case report presented a 19-year-old man referred from a secondary hospital with complaints of diarrhea for one month before hospital administration. The symptoms happened five times a day with residue in the stool. Mucus or bleeding was not found. Around ten days prior, the polyp came out from the anus, but the patient could pull it back by himself. Diarrhea had been recurring since 2014. The patient then underwent polypectomy (while still children) and until now has undergone polypectomy 11 times. Abdominal CT scan showed multiple polyps with varying morphology in the luminal mucosa of the duodenum, jejunum, ileum, descending colon, sigmoid colon, and rectum, in accordance with the presentation of Peutz-Jeghers syndrome. The colonoscopy examination found a Peutz-Jeghers appearance after a polypectomy with a hemoclip installed. The patient was diagnosed with Peutz-Jeghers Syndrome post polypectomy. The patient received a plan for post-operative complete blood count examinations and periodic colonoscopies. Conclusion: PJS is an important diagnosis to consider in young patient with polyposis, even without mucocutaneous pigmentation.Keywords: Peutz-Jeghers syndrome, polyposis, polypectomy
Successful Management of Early Postoperative Small Bowel Obstruction Using Steroid: a Case Report
Authors: Luthfi Muhammad , Maghfirah Desi , Yusuf Fauzi , Abubakar Azzaki , Syahrin Alfi , Purnomo Avisena Gatot
Published: December 2024

Background: Early Postoperative Small Bowel Obstruction (EPSBO) is a primary factor contributing to death and morbidity after pelvic and abdominal surgery. Although it is frequently regarded as a surgical emergency, the most recent research indicates that non-operative management is always preferable unless there are complications.Case: A 53-year-old woman came with symptoms of small bowel obstruction and a history of hysterectomy three weeks earlier. The patient refused surgical intervention, so a conservative approach was taken. She was given methylprednisolone 500 mg/day in two doses daily for three consecutive days, in addition to nasogastric tube insertion and symptomatic therapy. After three days of follow-up, the patient showed symptoms improvement, and the abdominal X-Ray and CT Scan showed no abnormal findings.Discussion: The majority of Early Postoperative Small Bowel Obstruction (EPSBO) cases, according to the most recent research, may be managed without surgery. Additionally, due to their anti-inflammatory properties, some medications, like corticosteroids, have been found to be beneficial and effective for EPSBO. This is because they may help resolve the obstruction and lessen the edema and fibrin deposition associated with EPSBO following abdominal surgery.Conclusion: Conservative therapy with steroids appears promising due to its lower risk profile and greater patient comfort. However, the exact mechanism and its efficacy in treating EPSBO have yet to be fully concluded, so further research is still needed.Keywords: Corticosteroids, non-operative intervention, small bowel obstruction

A pesca comercial e de subsistência desempenham um papel crucial na economia da região amazônica. Assim, para contribuir com a construção de políticas públicas voltadas para o setor. Esse trabalho tem como objetivo descrever o processo de elaboração do zoneamento participativo dos ambientes dos complexos de lagos Preto, Itaúba e Tigre inseridos na Reserva de Desenvolvimento sustentável Mamirauá, no Amazonas, visando a conservação e manejo do Aruanã (Osteoglossum ssp.). A abordagem metodológica adotada fundamentou-se na técnica de mapeamento participativo, empregando grupos focais como instrumento para a coleta de informações acerca dos ambientes em questão, bem como de seus usos e usuários. Ao final do processo, foram identificados sessenta e quatro ambientes, distribuídos em três categorias distintas de uso. A etapa subsequente consistiu na definição de diretrizes orientadoras para as atividades pesqueiras nas áreas delimitadas, a partir das contribuições fornecidas pelos participantes do grupo focal. Os resultados apresentados contribuem não só para uma compreensão mais abrangente das práticas de pesca na região, mas também para a formulação e implementação de diretrizes para a gestão dos recursos naturais pesqueiros. A técnica proposta colabora com debates técnico-científicos acerca da regulamentação e regulação do acesso aos recursos naturais. Destaca-se, ainda, a importância desse enfoque participativo na construção de políticas públicas voltadas para a comunidade de pescadores e pescadoras artesanais, fornecendo elementos essenciais para a elaboração de planos de manejo destinados à conservação de espécies de interesse comercial.
