Introduction: Ethical LIVING is a lifestyle in which all areas of human existence and work are formed and flow around ethics. That is, a person who wants to live morally, in all areas, tries to know the ethical considerations related to that area and follow them in practice and live according to them. The current article is research on the moral system of Thomas Aquinas with a focus on examining the nature of the moral goal of human life and the moral rationality of such a life. Material and Methods: The present review study examined bioethics from the perspective of Thomas Aquinas in a descriptive manner. In order to achieve this goal, articles related to research keywords from Thomson Information Institute, Science Direct and Pub Med were examined and books related to the views of Thomas Aquinas were studied. Conclusion: The results of this study show that according to Thomas Aquinas's view on man, becoming like God and realizing God's image in material life and seeing God in the hereafter is the moral goal and eternal happiness of man. Also, Thomas Aquinas believes in the moral rationality of such a life from both perspectives-having a reason to live morally and the usefulness of such a life.

Background and Aim: Culture and specific staining (including Zeil-Nelson and fluorescent methods) are standard measures for the diagnosis of tuberculosis (TB). Because these methods are time-consuming and, sometimes, due to their low accuracy faster and more accurate methods are necessitated. Methods, which can substitute invasive procedures, when obtaining smear samples and culture is not possible, and in addition to being simple and fast, they have an acceptable diagnostic accuracy.The aim of the present study was to verify the diagnostic value of blood Polymerase CHAIN Reaction (PCR) method in pulmonary TB.Materials and Methods: This case-control study included 64 proven pulmonary TB cases (according to The National TB Protocol) and 28 subjects who were completely healthy. 4.5ml of blood was derived from each participant and then mixed with 0.5ml EDTA. Finally, DNA extraction and PCR testing using SI 6110 primers was performed for all blood samples.Results: Mean age of the cases and controls was 49.8±18.6 and 48.2±18.5, respectively. 49.2% of the cases and 25% of controls were male. Blood PCR in 23 patients with TB was positive, but none of the controls had a positive PCR (thus, sensitivity of 35.7% and specificity of 100%).Conclusion: With regard to specificity of 100% in PCR method (despite its low sensitivity), in conditions where there is no access to an appropriate specimen, a positive blood PCR can obviate invasive procedures and rapid and definitive diagnosis of the disorder and timely treatment of the patient, his life is saved.

LIVING cationic ring-opening polymerization of cyclic ethers in the presence of diol was modeled using the method of moments. A widespread kinetic model was developed based on the previous experimental studies. Then, the moment and population balance of reactants were obtained. Modeling results were employed to study the influence of initiator and water amounts (as the impurity) as well as feeding policy in polymerization kinetics and final properties of the polymer. In addition, the sensitivity of modeling results to initiation, backbiting, and finally propagation via activated monomer reactions were investigated. Results showed the population of CHAINs is the function of their precursors. In a typical polymerization, CHAINs with diol functionality are the majority. Therefore, most of the polymerized monomers are incorporated into those CHAINs. This makes the CHAINs with diol functionality the determining group in Molecular Weight Distribution (MWD). The kinetics of polymerization and properties of the reactor’ s product are highly dependent on the ratio of the rate of propagation via Activated Monomer (AM) mechanism to the rate of propagation via active CHAIN end (ACE). An increase in this ratio decreases the probability of occurrence of backbiting reaction. Therefore, cyclic dimers are less formed and MWD narrows. On the other hand, decreasing this ratio results in less diol reacted with protonated monomers. Consequently, the rate of regeneration of initiator and hence the rate of polymerization is decreased. These findings give complete facts about the ring-opening syntheses of polyethers and are valuable for evolving new grades as well as optimization current processes.

Background: The genitourinary system is one of he most common sites of infection in non-pulmonary tuberculosis (TB). The clinical symptoms and radiologic findings of urinary TB are nonspecific. Current diagnostic tests are of low sensitivity and labor-intensive. Therefore, this study was aimed to evaluate diagnostic value of urine PCR in genitourinary tuberculosis (GNTB).Methods: This was a descriptive study on 33 patients with confirmed genitourinary TB. Demographic data, clinical symptoms, laboratory and radiologic findings were collected. For each patient, three consecutive early morning urine specimens were examined by PCR. The diagnostic value of PCR in mycobacterium tuberculosis (MTB) in comparison with standard microbiological methods was assessed.Findings: There were 33 patients with a mean age of 47.27 16.1 years. The most common presenting symptoms were irritative voiding symptoms (51.5%), flanks pain (27.2%), gross hematuria (9%) and suprapubic pain (9%). Laboratory findings in U/A were hematuria (75.8%) and pyuria (60.6%). IVU was abnormal in 61.5% of patients. Most common abnormalities were pyelocalyceal dilation (44%), ureteral stricture and hydroureter (37%) and multiple small calyceal deformities (25%). Of the 33 patients PCR for MTB was positive in 16 cases (48.5%). In patients with abnormal IVU, PCR was positive in 62.5%.Conclusion: A high index of clinical suspicion is necessary for diagnosis of GUTB. PCR is recommended for instant diagnosis and screening before further examination, it cannot be the only method in identification of GUTB.

Today, many different methods are applied for the correct use of foods and to prevent their deterioration. Ensuring healthy conditions for people in food consumption and consumption of healthy foods is very important for human welfare. In this study, food spoilage, the factors that cause food spoilage, its effects on a global basis, food transport systems (cold CHAIN) and measures that prevent or delay food spoilage are discussed.

A B S T R A C TSatisfaction is considered one of the effective methods for evaluating the success of urban development plans and projects, and it is a tool to measure which type of housing and residential environment meets the needs, expectations, and aspirations of residents. This article aims to compare Amiriyeh and Pay-eToop neighborhoods in Bojnord city in terms of residents' satisfaction with LIVING in these neighborhoods. Using a questionnaire, the data was obtained by a survey from 229 heads of sample households LIVING in Bojnoord city. The residents' satisfaction is analyzed by 26 indicators set as home and neighborhood indices. The data is entered into SPSS software to run the One Sample T-Test and calculate statistical parameters. Also, the data is entered in Arc GIS in accordance with the UTM coordinates of the responder's locations to provide a GIS point layer to use zoning maps to be drawn. Residential satisfaction is lower than average and slightly higher in Pay-eToop than in Amiriyeh. Also, the average score of the indicators that are set as home indices is lower than those for neighborhood indices. The zoning maps indicate that most parts of the neighborhoods show an average level of satisfaction with housing, and the maps of different indicators are not much different from each other. The role of physical indicators in low satisfaction is much more significant than social indicators. To improve satisfaction, paying attention to the neighborhood regeneration and improving the housing quality is necessaryExtended AbstractIntroductionSatisfactory housing is one of the most valuable aspects of life and one of the main elements of people's LIVING standards. The higher the level of satisfaction with a place, the more people will feel a sense of belonging to that place and feel more relaxed about being there. The feeling of satisfaction from a place can cause the positive effects of the place in the process of relationships in which the environment is being formed and carried out. On the one hand, satisfaction measurement is considered one of the effective methods of evaluating the success of urban programs and plans. On the other hand, it is a tool to measure which type of housing and residential environment currently meets its residents' needs, expectations, and aspirations. MethodologyThe residents' satisfaction is analyzed by 26 indicators set as home and neighborhood indices. A questionnaire gathers the data. Household heads in the studied neighborhoods (Amirieh and Pay-e Toop) are randomly selected as 229 sample people. The sample people evaluate the items in the questionnaire in a 5-range of the Likert scale from very high to very low. The qualified range was then changed to quantified scores from 5 to 1. Afterward, they were entered into SPSS software to run the One Sample T-Test and calculate other statistical parameters. The address of each respondent is included in the questionnaires, and based on the address, the UTM coordinates of the respondent are determined using Google Earth. Then, the information from the questionnaires is entered into the GIS according to the coordinates to provide a GIS point layer for drawing zoning maps. Results and discussionThe score of 2.75, which is the average figure of the evaluation scores for all the indicators of both neighborhoods, indicates that residential satisfaction is lower than the assumed average score (3). The average scores are 2.90 and 2.57 for Pay-e Toop and Amirieh neighborhoods, respectively, and they indicate that the residential satisfaction in the first is slightly higher than the other. Pay-e Toop is the oldest neighborhood in Bojnoord, which accommodates the traditional complex of shops (Bazar) and essential physical elements of historical eras, such as the city's citadel. In addition to the high proportion of immigrants, it also includes deep-rooted and native families that have strong social relationships. Also, the average score for the neighborhood indices is slightly higher than for the home indices. The average figure for all 26 indicators is lower than the assumed average score (3) and indicates a lower residential satisfaction. Five indicators with the higher satisfaction score are as follows: relationship with neighbors, LIVING in the ancestral neighborhood, the situation of streets and ways, LIVING with relatives, and the quality of wastewater disposal. On the contrary, lower satisfaction scores belong to the indicators of access to shopping centers, healthcare service centers, the size of homes, and access to public transportation, respectively. Despite the fame of the gardens of Bojnord in previous centuries, in recent decades, most of the gardens disappeared, especially in the city's central business district, which corresponds to the two studied neighborhoods; there is a small area of land covered by parks and green spaces. Green spaces are mainly the small green strips on the edge or in the middle of the streets. For Amiriye and Pay-e Toop neighborhoods, the Pearson correlation coefficient between the respondents' education levels and their scores of residential satisfaction are -0.36 and -0.23, respectively. It implies that residential satisfaction has an inverse relationship with education. Also, the correlation coefficient between the residence length in the neighborhood and residential satisfaction scores are +.001 and -0.29, respectively (for Amirieh and Pay-e Toop neighborhoods). It also indicates no relation for the first neighborhood and an inverse relation for the other.The zoning map of all the indicators shows that in more than 90% of the neighborhood area, the level of satisfaction is in the medium range. In Amirieh, the parts with low satisfaction are scattered. It can be said that the northeastern edge of the Amirieh neighborhood and the southwestern edge of the Pay-e Toop neighborhood have lower satisfaction. ConclusionThe role of physical indicators in low satisfaction is much more significant than social indicators. The physical components of the neighborhoods caused a low level of satisfaction. On the contrary, higher satisfaction is revealed from the socio-cultural components. Households prefer the quality of services more than the availability of services. In medium-sized cities such as Bojnoord, neighborhood relations, closeness to relatives, and LIVING in neighborhoods where the ancestors lived are still decisive in creating residential satisfaction. To improve life satisfaction, paying attention to housing quality and the regeneration of both neighborhoods is necessary. Also, improvement, retrofitting, enhancing the quality of the building, and improving the quality of urban services, especially healthcare services, public transportation, and commercial services, should be considered. FundingThere is no funding support. Authors’ ContributionAuthors contributed equally to the conceptualization and writing of the article.
