Abstract Organoleptic assessment of fresh fish includes specifications for the quality of the eyes, gills, mucus, odor, texture and flesh (color and appearance). However, not everyone has knowledge about it. This research uses the tiny yolov2 to facilitate the determination of fish freshness levels (good quality, medium quality, poor quality) correctly and fast. There are a few stages in this research, included organoleptic test accompanied by taking fish eye image dataset every hour, processing organoleptic test data labeling, training, and validation. There are three types of fish used, consists of Rastrelliger, Euthynnus affinis, and Chanos chanos. Detection of fish freshness level for three species was successfully carried out with the result of average precision is 72.9%, average recall is 57.5%, and accuracy is 57.5%. The factors that affect the prediction results in this study is the collection of datasets before the training process is carried out consisting of fish samples obtained from traditional markets, which are considered inadequate so that it affects the organoleptic test process itself, the organoleptic test that was carried out as a reference for image sorting was considered inaccurate because it used less than 30 untrained panelists and dataset imbalance.

Bridge maintenance is one of the major issues of infrastructure problems. Deterioration of a bridge’s structure will continuously increase without proper maintenance. This condition will adversely affect the service life of a bridge. Moreover, the damage will also have a direct impact on structural and functional failure of the bridge. This paper aims at identifying the damages of truss bridges and determining the most significant criteria and sub-criteria used in prioritizing bridge maintenance. Analytical Hierarchy Process (AHP) was used to assess the most important criteria that give significant weight to bridge maintenance analysis. The objects of research were nine truss bridges with a wide range of types and levels of damage. It was found that there were approximately 900 m' of components damaged at the railing of Baruga Bridge and 227 m' truss damages due to poor quality of the galvanized paint. Furthermore, based on the analysis, the most significant criteria were the level of damage (27.6%), the technical aspects (25.7%), the finance (21%), the vehicle load (13.6%) and the resources (12%). The results of this research showed important findings in determining the priority scales for bridge repair and maintenance systems.

 Fresh and frozen seafood products (fish, shellfish, crustaceans, molluscs) in wide use in Croatia and typical of the Mediterranean diet, were examined for the presence of microbiological contamination through the winter and summer seasons. Total bacterial counts of aerobic mesophilic bacteria (AB), aerobic psychrophilic bacteria (AP), Salmonella spp., Enterobacteriaceae, Escherichia coli, Staphylococcus aureus, sulphite-reducing clostridia (SRC), Listeria monocytogenes, Vibrio cholerae and V. parahaemolyticus were measured. The microbiological quality of individual samples varied widely between animal species and also between winter/summer seasons regarding total counts of aerobic mesophilic and psychrophilic bacteria. The poorest quality was for (both summer and winter) fish samples, where 66.6 % of fresh and frozen fish were found unacceptable by Croatian standards. The overall prevalence of V. parahaemolyticus was 5%. Its recovery rate was higher in fresh/frozen shellfish in both seasons than in other specimens or other storage/season conditions. Fresh crustaceans sampled in winter demonstrated significantly higher aerobic mesophilic counts than frozen ones. Unacceptable Enterobacteriaceae levels were obtained in 40% of the fresh fish summer samples. The results of this survey constitute an indicator of bacteriological contamination of a variety of seafood. The findings could serve as a basis for future testing of seafood, and possibly as a template for developing a regional/Mediterranean testing scheme on the microbial contamination of seafood in order to establish data with comparative epidemiological and statistical values.

Abstract. Aboagye E, Tano-Debrah K, Kunadu APH. 2018. Microbial quality of fish along with the Tilapia, African catfish and Sardinella artisanal value chains in Kpong and James Town, Ghana. Bonorowo Wetlands 10: 1-17. Fish from artisanal sources constitute the most critical animal protein in the Ghanaian diet. The availability and safety of fish on the Ghanaian market is, however now unpredictable owing to potential rapid microbial growth which results from high ambient temperatures and poor handling along the artisanal value chains. Little is know about the small-scale fish value chains as well as the food safety knowledge and processing practices of key stakeholders involved. This study aimed at mapping out the artisanal fish value chains of Tilapia (Oreochromis niloticus), African catfish (Clarias gariepinus) and sardinellas (Sardinella aurita), and assessing the food safety knowledge and handling practices of key stakeholders along the selected value chains. A survey using semi-structured questionnaires and involving 93 fishers, 40 retailers, 40 processors, and 120 consumers was carried out to investigate stakeholders’ knowledge and practices of food safety along the value chain. Samples of the selected fish species were taken along their respective value chains to test for the presence of safety indicators (Salmonella, Vibrio, and Listeria species), hygiene indicators (Staphylococcus aureus and Escherichia coli), and spoilage organisms (Pseudomonas spp. and Proteus spp.). The mean scores for food safety of retailers, processors, and consumers were found to be generally insufficient at 55%, 43%, and 67.3% respectively. The stakeholders also scored poorly in their handling practices with mean scores of 41.2%, 63.0% and 58.6% for fishers, processors, and consumers, respectively. Estimated fish losses were highest at the retailer and consumer stages of the value chain with reported injuries as high as 35 to 100%. Pathogens such as Clostridium perfringens, enteropathogenic Escherichia coli, Staphylococcus aureus, Listeria spp. And Aeromonas sobria were isolated from fresh and on processed ready-to-eat fish samples. Salmonella spp. and Vibrio spp. not detected on any of the samples tested. Mesophilic counts in the range of 7.96 ± 0.68 to 2.95 ± 0.23 log cfu/g reported from fresh fish samples, with similarly high fecal coliform counts averaging 3.11 log cfu/g. Processed fish samples had average total counts, fecal coliform counts, and yeasts and mold counts of 3.11, 2.27, and 2.45 log cfu/g respectively. Proteus vulgaris and Proteus mirabilis were the predominant spoilage organisms present in almost all the fresh fish samples. This study provided much-needed insight into the unsatisfactory safety and quality of artisanal fish on the Ghanaian market and the specific microorganisms associated with them along the value chain. It also established the link between the food safety knowledge and handling practices of stakeholders within the value chain, and the actual quality and safety of fish on the market.

Background: Diarrhoea is a major public health problem in children worldwide. It continues to be a major health challenge, especially in developing countries, despite the availability of regularly updated standard treatment guidelines. Non-compliance to such guidelines by the physicians has been a long standing story. The treatment is often marred with incapacitating prescription of drugs besides neglecting even the basic tenets of good prescribing. As a result, the quality of such prescriptions for diarrhoeal disorders in children remains poor. To gauge the magnitude of this problem in this setup towards possible corrective measures, the study was aimed to audit prescription practices in the management of acute and persistent diarrhoea in hospitalised children up to five years of age.Methods: An observational study was conducted in 100 patients of either gender in the age group up to 5 years admitted with acute and persistent diarrhoea. A detailed medical history from the parents/guardians and the details of prescription from the time of admission till the discharge of the patient were obtained. Quality of prescriptions was analysed using prescription quality index (PQI) tool, a validated comprehensive tool described by Hassan et al in 2010. Based on this tool, prescription with the total PQI score of ≤ 31 were interpreted as poor quality, scores with 32 to 33 as medium quality and scores 34 to 43 as high quality with a possible maximum score of ‘43’.Results: Based on the PQI tool for 100 children, 60 prescriptions were found to be of poor quality. Only 2 prescriptions were of medium quality, whereas 38 prescriptions were in high quality range. Average mean±SD score of prescriptions with poor quality was 25.2±1.48, ranging from 21 to 31. The mean±SD of prescriptions with medium quality was observed to be 32±0 and for prescriptions of high quality was 38.07±2.28. The total average mean score of all prescriptions was 30.23±6.50. Poor quality prescriptions were particularly observed for the patients with the diarrhoea with No dehydration.Conclusions: Prescription appropriateness in spite of available guidelines continues to be a big challenge in the adequate management of patients with diarrhoeal disorders under the age group of five years in a tertiary care centre in India.

Purpose – The aim of the article is to identify the limitations and critical issues in the way information in the real estate sector in Italy is currently managed, and propose the principles of a method that would provide information and comparison of the phenomenon of over-supply and non-rational land use. This study is based on a series of assumptions, the first of which is a definition of “unsold”, deemed to mean “the amount of new housing units neither occupied nor sold nor rented”. In effect, unsold stock can be considered as over-supply of construction. Design/methodology/approach – The article identifies the critical aspects in the determination of unsold real estate in Italy, starting from the available data and research already carried out; the results are often contradictory. The comparison with programming systems of building production adopted in other countries allows identification of the guidelines that can be used to better understand and combat the phenomenon. Findings – The assessment of the state -of-the-art provides a clear picture of the shortcomings and potential of the tools used to date to meet the need of studying a complex phenomenon with many obscure points. Following the empirical analysis comes out a picture of inefficiencies due to the poor quality of information, as well as the reluctance of data-sharing and -integration procedures by the institutional and market players. Research limitations/implications – The research produces solutions addressed to the Italian situation, but it identifies systems and methods used in other countries. Practical implications – The article suggests the collection systems and management information that can be used for a more accurate knowledge of unsold real estate. Social implications – The article focuses on some of the limits of the Italian real estate market, highlighting the need for greater transparency and how this can contribute to a more conscious approach to the market. Originality/value – The article seeks to provide the necessary answers to those who must understand the reasons of harmful effects for the market, such as overproduction; besides some models focused on three areas – the procedures, the organization and the market – are also proposed.

Tuna is one of the mainstay fisheries commodities that involve many of the ordinary fishermen. The handling usually still not follows the principles of good handling that causing the poor quality as the result.The aims of this research were to analyze and to determine the quality of tuna meat (the abdominal wall, dorsal fin, and caudal fin). Raw material yellowfin tuna meat prepared for the light, the meat section of the abdominal wall, dorsal fin, and caudal fin. The result of organoleptic analysis showed that the tuna meat was above the minimum value for the criteria of fresh fish. The result of TVB analysis showed that the meat on the caudal fin had the highest value and significantly different with the other, but still exist on the safe limits and on the fresh category. For the result of analysis in histamine, it shown that at the fourth hour the meat at the dorsal fin had the histamine content which were above the minimum that have been recommended. For the result of analysis in peroxide number, it shown that the tuna meat did not sustain the fat damage until the fourth hour after the catching process. And for the result of analysis in TPC, it showed that at the fourth hour the tuna meat on the pectoral fin had the highest number of total colony and significantly different with the other.<br />Keywords: handling, histamine, light flesh, microbiology, yellowfin

In accordance with the modern requirements of the international control system (HACCP), it is necessary to abandon the control of the final product for the purpose of identifying shortcomings, but to proceed to the preventive approach of eliminating potential sources of danger at all stages of production. A step-by-step system for controlling the quality of livestock products, in particular meat, in the absence of modern technology of primary processing and quality veterinary and sanitary control, is complex. Therefore, to ensure the safety and quality of meat, it is necessary to improve and scientifically justify the methods of their control, bringing it closer to international requirements. The purpose of our research was to monitor the safety and quality of slaughter products for pigs obtained in the conditions of the Odessa region. The material of the research was reporting on veterinary medicine (Form No. 6-vet., Form No. 5- vet., Form No. 2a-vet.) In the districts of the Odessa region for 2014–2016, which was processed statistically. The analysis has established that for 2014–2016. In the investigated areas, only 28846 pigs were slaughtered, and 74.48% of the slaughter took place. It was found that according to the results of the pre-blast inspection and post-mortem veterinary examination of pig carcasses, 83 cases of diseases, echinococcosis, were detected during the reporting period. For the reporting years, 17103 carcasses of pigs were supplied to the agro-food markets of the study areas. Employees of laboratories for veterinary and sanitary examination in the markets conducted 65417 laboratory studies: all carcasses of pigs were examined organoleptically (including cooking breakdown), trichinoscopy and studies for phychosis and other parasitic diseases were performed; The determination of physicochemical parameters and bacterioscopy of mascara were carried out in individual cases; radiological and other studies were not conducted. During the veterinary and sanitary examination, 662 cases of diseases were detected in the laboratories of veterinary and sanitary examination in the markets: 65 cases of non-communicable diseases and 597 cases of invasive diseases. And draws attention to the fact that 99.83% of the identified invasive diseases was echinococcosis. Comparative analysis of the results on the detection of cases of echinococcosis, depending on the location of Veterinary control, found significant discrepancies– after post-mortem veterinary and sanitary control, only 7.26–26.27% of cases are detected, in comparison with the results of veterinary and sanitary examination of slaughter products in laboratories for veterinary and sanitary examination In the markets. This imbalance, in our opinion, can be related to homestead slaughter and poor quality post-mortem Veterinary control during it. Summarizing the obtained results of the analysis, we can conclude that the management system for the safety and quality of slaughter products in pigs in the regions of the Odessa region at the present stage still relies on the analysis of the final product, not taking into account the preventive approach.
