Published: March 2024

Fish sauce is a food product made through a fermentation process from fish or fish waste. It has a distinctive taste and aroma as well as a long shelf life. Lactic acid bacteria activity is a crucial factor in the fermentation process. This study investigates the presence of lactic acid bacteria in processed tuna fish sauce (Thunnus sp) during the fermentation process. The research method used in this study is experimental, with a fermentation temperature of 50°C, various concentrations of papain enzyme treatment (A), including A1 (0%), A2 (9%), A3 (12%), and A4 (15%), different salt concentrations (B), including B1 (8%) and B2 (10%), and varying fermentation durations (C), including C0 (0 days), C1 (6 days), and C2 (12 days). The research results show that an increase in the total lactic acid bacteria (LAB) can lead to a more acidic fermentation condition, which inhibits the growth of other bacteria. Fish sauce with the addition of 15% papain enzyme hydrolyzes faster compared to the addition of 9% papain enzyme. This difference is due to variations in enzyme concentration, which can accelerate the hydrolysis process. Papain contains proteolytic enzymes that can break down proteins, softening the meat. The longer the fermentation process, the higher the growth of lactic acid bacteria, mainly due to the use of enzyme and salt concentrations.

This community service program discusses the implementation of the Stunting Awareness Community Movement in Kudamati Village, Ambon, which is carried out through the Real Work Lecture (KKN) Program by Pattimura University students. The main focus is the prevention of stunting, a child health problem in Indonesia that has not yet reached the 2024 RPJMN target. Stunting can have short- and long-term impacts, including developmental barriers, reduced immune function, and risk of chronic disease. The stunting rate in Indonesia is still high, including in Maluku. The UNPATTI KKN team conducted observations in Kudamati Village and found several barriers such as a lack of education about blood supplement tablets and the habit of giving formula milk instead of exclusive breastfeeding. The KKN program focused on education and service to the community to raise awareness of stunting. Priority programs include Implementation of Clean and Healthy Living Behavior in the Elementary School Environment, Stunting Awareness Movement Education for Mothers and Families, and Stunting Awareness Movement Education for Adolescent Girls. Education and service methods were applied through socialization, leaflet distribution, health checks, and distribution of blood supplement tablets.The results included an increase in community awareness, particularly in the school and posyandu environments. The program reached its target audience and made a positive contribution to stunting prevention efforts. It was concluded that the program had a positive impact on the community, building awareness and increasing understanding of stunting prevention.

Elogio de la cautela en dos biografías latinas: Ático de Nepote y Agrícola de Tácito.
Authors: Schwartz Frydman Pablo
Published: March 2024

El propósito de este artículo es trazar un paralelo entre dos biografías de hombres públicos, que abordan momentos convulsionados de la vida política en la antigua Roma. Ático de Cornelio Nepote ilustra las turbulencias de las últimas décadas de la República romana, las guerras civiles y el comienzo del largo período en que Octavio controlará el Estado romano. Por su parte la biografía de Agrícola, escrita por su yerno Tácito, revela aspectos sombríos de la vida política en los años finales del principado de Domiciano, último de los príncipes de la dinastía Flavia. Como es usual en el género biográfico, la narración de las acciones de los personajes se alterna con una descripción y análisis de su carácter. Ambos personajes se destacan por la cautela con la que se enfrentaron a situaciones adversas[1].
Carta editorial. Elogio y vituperio en el discurso social
Authors: Schwartz Frydman Pablo
Published: March 2024

Constituido originalmente como tercer género retórico, el epidíctico o demostrativo fue contrapuesto a los llamados géneros prácticos —deliberativo y forense— y considerado desde los primeros teorizadores una variedad de definición más lábil. Caracterizado por las especies del elogio y del vituperio, se vinculó a funciones sociales específicas, como elogios fúnebres, discursos de celebración, solemnidades religiosas e institucionales de la más diversa índole. Por estar destinado a la exhibición y tener como fin el deleite del público, el epidíctico estableció lazos estrechos con prácticas sociales y géneros discursivos variados.

Effectiveness of Family Tuberculosis Treatment
Authors: Duzhyi І.D. , Bondarenko L.A. , Hlynenko V.V. , Shevchenko V.P.
Published: March 2024

Knowledge about tuberculosis dates back to 4—5 thousand years BC. For a while, it seemed that the infection might soon be overcome. However, since the late 1980s, there has been a significant increase in the incidence and mortality of both pulmonary and extrapulmonary tuberculosis. In parallel to this, there has been an emergence and increase in the quantitative and qualitative resistance of mycobacteria to antibacterial drugs, especially the multidrug-resistant type, reaching 60—65 % among patients treated for 5—6 months. The effectiveness of chemotherapy for this type of tuberculosis in Ukraine does not exceed 40—45 %, which determines the urgency of the problem.
Objective — to compare the effectiveness of treatment of patients — sources and family contacts of tuberculosis.
Materials and methods. Under our observation there were 406 individuals with familial-type tuberculosis, who were divided into the comparison group (source of tuberculosis) — 207 people, and the main group (contacts) — 199 people. The examinations were conducted according to the established standards. Treatment followed the protocols of the Ministry of Health of Ukraine.
Results and discussion. The sources of multidrug-resistant mycobacteria in the comparison group were found in 42.6 % of patients, and among the family contacts of tuberculosis — 39.4 % (p > 0.05), indicating a similar origin. Drug-sensitive forms of tuberculosis mycobacteria were detected in 20.0 % of the comparison group and 20.2 % in the main group. We failed to abacillate 27.8 % patients in the comparison group and 8.1 % in the main group, which is 3.5 times less (p < 0.001). Relapses within 2 years observation occurred in 16.4 % of convalescents in the comparison group and 9.0 % in the main group. Mortality rate of the comparison group is at 13.0 % and 8.5 % of the main group patients. Social rehabilitation of individuals capable of working in the comparison group occured in 16.5 %, and 24.6 % in the main group, which is 1.5 times more (p < 0.05).
Conclusions. Therefore, the effectiveness of patient treatment in the main group significantly exceeded that of patients in the comparison group, confirming the importance of organizational measures in phthisiology.

Our observation of the pancreatic cancer diagnosing difficulties in a patient with HIV infection with generalised lymphadenopathy is presented. The patient’s HIV infection was diagnosed 8 months before hospitalisation, he did not receive antiretroviral therapy. He came to the doctor already in a serious condition, when severe intoxication syndrome, weight loss, abdominal pain radiating to the lower back and diarrhea were noted. The patient was hospitalised in a serious condition, where he spent 42 days. The patient had severe immunosuppression since hospitalisation time (CD4+ lymphocyte count was 20 cells, viral load was more than 3,000,000 RNA copies/mL). He did not suffer from tuberculosis before. Considering the severe immuno­suppression and doubtful lipoarabinomannan test (LF-LAM), it was impossible to exclude a tuberculous etiology of lymphadenopathy. Mycobacterium tuberculosis was not detected either in the sputum or in the pleural fluid. However, non-tuberculosis mycobacteria were found in the sputum. The patient underwent two contrast-enhanced computed tomography scans of the abdominal cavity, which revealed increasing generali­sed lymphadenopathy and hepatosplenomegaly, with no signs of neoplastic lesions of the pancreas. Therefore, the diagnosis of oncopathology was confirmed only pathohistologically. Despite massive complex therapy during inpatient treatment the general condition progressively worsened, intoxica­tion syndrome, multiple organ failure and polyserositis increased. The cause of death was the progression of multiple organ failure on the background of an HIV-related disease with manifestations of malignant neoplasms (undifferentiated pancreatic cancer with foci of necrosis and destruction of tumor tissue with metastases in the lymph nodes and liver, along with a non-tuberculous mycobacterial infection affecting the intra-thoracic lymphatic nodes. Thus, timely intravital diagnosis of pancreatic cancer in HIV-infected patient with generalised lymphadeno­pathy and those with severe immunosuppression may cause difficulties, because CT signs and other manifestations of pancreatic lesions may not be detected. Severe immunosuppression and a doubtful LF-LAM test made it impossible to rule out the tubercular etiology of lymphadenopathy. At the same time, generalised lymphadenopathy was a manifestation of metastases and non-tuberculosis mycobacterial infection.

About 20 % of people who fell ill during the COVID-19 pandemic had a severe course of the disease, which was accompanied by various complications. One of these complications is the disappearing lung syndrome, which can be observed both in the acute period of the disease and in the post-COVID period. Under the mask of pulmonary complications of COVID-19, rare interstitial lung diseases may be diagnosed late. COVID-19 is characterised by the development of systemic thrombovasculitis against the background of a hyperimmune response caused by SARS-CoV-2. These pathological processes can lead to the formation of giant multicompartmental cystic cavities in the lungs, which are similar to those observed in lymphangioleiomyomatosis (LAM).
Objective — to investigate the possibility of differential diagnosis of the disappearing lung syndrome in lung lymphangioleiomyomatosis and the complicated course of viral pneumonia COVID-19 using digital software processing of CT data
Materials and methods. The data of CT lung of patients with LAM and patients with a complicated course of viral pneumonia COVID-19 were analyzed in dynamics. CT was performed on an Aquilion TSX-101A Tochiba scanner (Japan) with subsequent digital processing using the Dragonfly program, OBYECT RESEARCH SYSTEMS (ORS), Montreal, Canada, and comparison of the obtained results with pathomorphological changes. Examples of own observations are given.
Results and discussion. Researched of changes in the structure of the lung parenchyma in cases of LAM and patients with a complicated course of nosocomial viral pneumonia of COVID-19 were studied by means of software digital processing of CT OGK data. The obtained results in the form of segmented histograms are correlated with pathomorphological changes in lung tissue.Digital software processing of CT data clearly reflects the morphological structure of the lung parenchyma and allows diagnosis and differential diagnosis of «disappearing lung syndrome» in various diseases.
Conclusions. Carrying out digital software processing of CT OGK data allows differential diagnosis of various pathological processes, which are radiologically manifested by the same symptoms.

Method of catching, type and size of fish, movement of fish, weather and condition of fish before catching are factors that affect fish freshness. Fish freshness can be determined physically (organoleptic/sensory), physically and microbiologically. The decline in fish quality can be seen from the speed of entering the rigor mortis phase. The rigor mortis phase is the process of convulsing the organs in the fish's body due to the flow of oxygen in the fish's body tissues. Fish that move quickly and fish that are "sick" enter the rigor mortis phase and decay more quickly. Post-harvest handling greatly determines the freshness or quality of aquatic commodities. One of the postharvest handling that is often applied is cooling and freezing.

Method of catching, type and size of fish, movement of fish, weather and condition of fish before catching are factors that affect fish freshness. Fish freshness can be determined physically (organoleptic/sensory), physically and microbiologically. The decline in fish quality can be seen from the speed of entering the rigor mortis phase. The rigor mortis phase is the process of convulsing the organs in the fish's body due to the flow of oxygen in the fish's body tissues. Fish that move quickly and fish that are "sick" enter the rigor mortis phase and decay more quickly. Post-harvest handling greatly determines the freshness or quality of aquatic commodities. One of the post-harvest handling that is often applied is cooling and freezing.

Currently, the Surabaya city government has provided spaces for micro, small, and medium enterprises (UMKM) or street vendors to sell their products. With the establishment of a central culinary tourism area by the government, it is expected to help the local community, especially the people of Surabaya. Research has been conducted to identify potential problems, such as the influence of entrepreneurial motivation, personal independence, and entrepreneurial knowledge on business success. Unequal competition contributes to uneven business success among the vendors. The lack of entrepreneurial motivation, personal independence, and supported entrepreneurial knowledge can lead to unequal business success in the culinary tourism center of Bratang Binangun, Surabaya.This study utilized a quantitative research method and employed a census method. A questionnaire was distributed to the vendors as the research instrument. The sample size consisted of 32 respondents, determined through a census method. Data analysis was performed using the Independent Sample Test. The research findings indicate a significant influence (0.000 < 0.05) of entrepreneurial motivation, personal independence, and entrepreneurial knowledge on business success in the culinary tourism center of Bratang Binangun, Surabaya.

This study purposed to describe the development and produce elementary linear algebra course modules on system of linear equation (SLE) and matrices integrated with Prezi learning media that are valid, practical and effective. This development research referred to the development design steps developed by Allesi & Trollip. The development design is grouped into three development procedures, which include: planning, design, and development stage. The product trial consisted of an alpha test conducted by two material experts and two media experts, as well as a beta test which was carried out through 2 stages, beta test 1 (small group trial) to 8 subjects; representatives of two students at cohort 2019/2020, 2020/2021, 2021/2022, and 2022/2023. Beta test 2 was conducted on 70 students who took the Elementary Linear Algebra course in cohort 2023/2024. Data collection used questionnaires for material experts, questionnaires for media experts, student response questionnaires, and tests. The developed module has several advantages. First, the material is prepared based on the results of research that has been done in previous studies so that it can minimize epistemological learning obstacles. Second, it is integrated with Prezi-based learning media that supports a deeper understanding of SLE content material.

the concept of limit equilibrium and enab e only the calculation of the critical height or the minimum factor of safety of a slope. These methods are not usually concerned with the stress distribution within a slope either above or below assumed surfaces of failure. This task can be done through the finite element method. In this paper, this method is used for the analysis of embankments. It was found that a good agreement could be obtained between the simple non-linear elastic-plastic finite element analysis, adopted in this paper, and sophisticated analyses which deal with plastic behavior of soils. This can be done when choosing the appropriate material parameters.
GENERATION RESCHEDULING FOR ALLEVIATING OVER LOADS CAUSED BY CONTINGENC

Contingency analysis is a valuable tool for a reliable planning and secure operation of a power system. Centingency analysis techniques must consider the impact of voltage effects as well as line flow effects. If the potential outage of a line or a generator would result in the overl rload of another line, then the system is said to be vulnerable. Without line overloading correction it may cause cascade outages and lead to failures in the whole system.

An efficient contingency analysis model for detecting both branch MVA flow violations and bus voltage limit violations is presented. A fast technique has been developed for automatic contingency ranking and selection of contingency cases for a power system contingency analysis study A contingency list is built containing line and generator outages which are ranked according to their expected severity. System voltage performance index is used to assess events severity Another model that was used for line over-loading correction is based on a pseudo inverse method that was used to solve a non-square system of equations based on Lagrange's theory in optimization These proposed models have been tested on the Iraqi National Grid system(case study) with 29 buses and 46 branches.

A boundary element numerical algorithm has been developed for the determination of stresses anddeformations around cavities and tunnels. A study of the influence of depth below the groundsurface on the distribution of stresses and deformations around cavities and tunnels is presented inthis paper. The soil is assumed to behave linearly elastic.A computer program has been built to perform the numerical computations. The results show thatwith increasing the depth of placement of tunnel or opening below the ground surface, the settlements decrease. The maximum stresses occur at the haunches of the tunnel rather than at the crown. For the circular cavity that is considered in this paper, it was found that with increasing the depth below the ground surface (depth/tunnel diameter > 3), the surface settlements do not exceed 6 % from those obtained for the case of no-cavity condition.

A study has been done to analyze the total production system by developing a computer model. Everycomponent of the production system has been programmed individually and then linked in the compositeproduction system computer program. These components are; reservoir component, vertical component,surface choke component and finally horizontal component.Each of the previous components are developed using various equations or models to determine thepressure loss thorough that component. In the current study the Wiggins method has been used tocalculate the IPR curves. The vertical and horizontal components are developed using the unifiedmechanistic model of Gomez. Lage mechanistic model has been used to calculate the pressure lossesthrough annulus. Perkins mechanistic model is used to calculate the pressure loss through surface chokes.A filed example problem is presented to analyze the production system. This example has been usedto determine the optimum system design which maximizes production rate for a set of condition.

This paper introduce a new method for using a systolic array to perform the one, and two dimension discrete wavelet transform (1-D DWT, and 2-D DWT). The 1-D needs only a semi-systolic array for its realization. However, it was found that the 2- D method needs the combination of two types of semi-systolic array into one systolic array to achieve its implementation.
