POSLOVI REPUBLIČKE UPRAVE SA OSVRTOM NA INSPEKCIJSKI NADZOR
Authors:   University of Kragujevac, Faculty of Law, Rapajić Milan
Published: May 2022

In this paper, the author writes about the affairs of the state administration of the Republic of Serbia, which are numerous and heterogeneous and cannot be brought under one legal regime. Attention was first drawn to the decisions of the Civil Service Law of 1992, which had to follow the decisions of the 1990 Constitution. Namely, the 1990 Constitution listed the affairs of the state administration. This means that it is not just the abovementioned executives as in the 2006 Constitution. This means that it is not just the abovementioned executives as in the 2006 Constitution. The 1992 law is "interesting" also because of the length of its implementation with regard to inspection provisions, which have been in force for 24 years, because there is no systemic law in this area. The provisions on inspection in the Civil Service Act of 1992, meanwhile, became anachronistic and it was necessary to pass a comprehensive Law on Inspection beforehand. It is not only for these reasons that the jobs and tasks of the state administration under the Civil Service Act 1992 are presented, along with theoretical views from that time. The 2005 Law on Public Administration introduces seven groups and tasks of the state administration into the legal order of Serbia, namely: 1) participating in shaping the Government's policy; 2) monitoring the situation; 3) enforcement of laws, other regulations and general acts; 4) inspection supervision; 5) taking care of public services; 6) development jobs and 7) other professional jobs. These jobs can be further classified into administrative and non-administrative. It was pointed out that the Law on State Administration of 2005 does not mention administrative control, which cannot in any way lead to the conclusion that in the legal order of the Republic of Serbia this job of state administration is not performed. The 2005 Act only regulates inspection supervision as a special type of control exercised by state administration bodies in relation to other entities. The subject of inspection supervision is the lawfulness of the work and conduct of natural or legal persons, and is carried out by direct inspection. Special attention was paid to the article on inspection. More specifically, attention was paid to the reasons for the adoption of the Inspection Supervision Act of 2015 and the basic characteristics of inspection supervision. At the end of the paper, attention is drawn to the introduction of "surreptitious purchases" in the Serbian positive-legal inspection system based on the Law on Amendments to the Inspection Supervision Act 2018. Among other things, the final considerations indicated that "covert purchase" was a separate inspection method and means of proof. It is argued that this specific method of inspection will accelerate fair competition and be one of the means in the hands of the state administration to curb the informal economy.

Published: May 2022

Development of drug delivery systems based on branched biocompatible polymers is one of the most promising areas of modern nanopharmaceutics. Researchers have been exploring this area several decades now, and the results of their efforts quickly find their way into production. Dendrimers, a new class of universal synthetic polymers with a highly functional surface, have a number of unique properties: constant size, high degree of branching, multivalence, solubility in water, definite molecular weight, internal cavities. With the release of VivaSol gel, the first dendrimer-based commercialized product, the "model range" of dendrimer carriers has grown significantly. Poly(amide-amine) (PAMAM) dendrimers, which consist of an alkyldiamine core and tertiary amine branches, are believed to be among the most promising compounds that can be used in the development of the new generation drugs. However, they were kept out of the list of clinically acceptable compounds for a long time because of their toxicity, unclear behavior in living systems and pharmacokinetic profile, as well the difficulties associated with establishing a therapeutic dose. This review presents basic information about PAMAM dendrimers and attempts to assess the prospects of their application in treatment of various diseases, including COVID-19.

The role of Christianity in preventing domestic violence among Christian families among the Ikwerre people of the Niger Delta
Authors: Amadi-Nche Church-Hill
Published: May 2022

One of the issues facing Christianity in recent times is the issue of domestic violence. Domestic violence has been adjudged to be responsible for some broken marriages, resulting in psychological traumas, single parenthood, divorce, remarriage and even deaths of couples and children as witnessed among the Ikwerre people of the Niger Delta. Thus, the incessant cases of domestic violence have eroded the sacredness, love and permanence of most marriages in Ikwerre. What are the causes of domestic violence? What are the effects of domestic violence among Christian families in Ikwerre? This paper examines biblical view of domestic violence and the roles Christianity can play to prevent the occurrence of domestic violence among Christian families in the area? The paper employs descriptive, evaluative and phenomenological methods and argues that domestic violence is an abuse on humankind and a menace to the progress of Christian families which should be discouraged at all cost. The paper recommends that the Churches should initiate vibrant and viable pre-marital counselling sessions for intending couples, seminars on marriage and family life for the adherents provide material support and care for victims of domestic violence and also encourage victims of domestic violence to always speak up and report any kind of abuses on them to law enforcement agencies.
The problem of dirty hands and Christian participation in politics
Authors: Otite Stephen K.
Published: May 2022

Today, politics, in all its forms and kinds, has been negatively construed by many as a “dirty game,” so that anyone involved in it must at one point or the other soil his/her hands with evil deeds (immorality). Consequently, it is usual to find numerous individuals in the society especially Christians, refusing to participate or get involved in politics. Recognising the manifold fatal implications of Christians’ refusal to participate in politics, this paper, adopting the expository, analytic and critical methodologies of research, argues that the inescapable moral dilemmas in politics should not deter Christians from participating in politics. Besides, it is also argued in this paper that the task of political leadership is one that Christians should and must embrace as a way of fulfilling their vocation as “salt of the earth and light of the world.” Fundamentally, this paper, using the four approaches to Christian participation in politics identified by Lesie Griffin as basis, argues that it is possible for a Christian politician to refrain from immorality (doing evil). By so doing, this paper refutes the negative standpoints of Niccolo Machiavelli, Max Weber and Michael Walzer with regards to the possibility of a Christian politician keeping his/her hands clean.

Drug abuse is one of the top problems confronting nations and communities today. The study problem was the lack of a comprehensive approach that yields significant impact in addressing specific socio-economic challenges of alcoholism on the welfare of communities. The study objective was to determine the nature and extent of alcoholism in communities in Vihiga County. Social learning theory by Albert Bandura guided the study. Cross-sectional survey research design was employed. The sample size was 400.Primary data collection utilized questionnaires, interview guides, observation checklists and Focus Group Discussion guides. Secondary data collection utilized alcohol related resources. Cluster, proportional stratified and snow-ball sampling were used for household members. Census and purposive sampling were used on key informants. Quota sampling was conducted for business community. Quantitative data was analyzed using descriptive statistics specifically frequencies, percentages and mean. Qualitative data analysis and interpretation utilized data coding and narrative analysis. Results indicate that 50% believe that social factors lead to alcoholism while 20 % alluded unemployment as the main reason making Vihiga County a potential market for alcohol. The study concluded that, it will be easier to achieve positive results if government policies and laws are effectively implemented. The study recommends that; There is need to enhance discipline for the law enforcers to ensure they effect the Alcoholic Drinks and Control Act 2010 effectively without being corrupted or favoring/fearing anybody in the community. Justification of this study was that, alcoholism menace has social effects in the community which includes family breakages, domestic violence among others. Thus, alcoholism effects play a critical role in negatively affecting the communities’ economic welfare.

Published: May 2022

Purpose: Construction of Transmission lines is complicated and hazardous as they are mostly located in difficult hilly terrain. The study is aimed to identify the hazards during the construction and determine how the approach of Safety by Design can be used to eliminate/control such hazards in the project under implementation at the site of Burtibang Paudi-Amarai Tamghas Sandhikharka Gorusinghe 132 kV Transmission Line Project, Nepal.
Design/Methodology/Approach: The Safety by design guidelines, regulations, and manual were consistently referred and Observation with Checklist, KII (Key Informant Interview), Likert scale- based Questionnaire survey were conducted to apply safety by design followed by Chi-square test, Kendall rank correlation coefficient analysis. Cronbach’s alpha assures reliability and literature comparison assures validity.
Findings/Result: Erection, Stringing & Excavation were found as most risky activities followed by Lifting & transportation and Concreting. These activities constituted of various hazards. Mechanical hazard was found to be the most prevailing hazard of all followed by Physical, Physiological, Psychological, Biological and Chemical hazard. Working location (top of tower), Slippery surface & Hand tools were the major mechanical hazards whereas Heat & humidity was the major physical hazards. Also Working posture/Bad ergonomics and Carrying overload were the major physiological hazards whereas working pressure/deadlines/target, Wages & leave and food & accommodation were the major psychological hazard. Similarly Mosquito & Snake bites were found to be the major biological hazards whereas Silica, Sand & Cement dust were the chemical hazards in the site. Despite most of the Clients and Contractors have responded that they have heard about SbD, it was found that SbD was not implemented in the site. Most of these hazards can be prevented by adopting the SbD approach in early design phase.
Originality/Value: It is action research. This study helps to identify the possible hazards in transmission line construction and use the concept of SbD approach to eliminate or control (if not possible) those hazards.

After 3 years, we have collected 500 reports and are beginning to identify failure occurrences and trends for certain taxa.
The Use of Temperature Threshold Treatments in the Control of Fireblight on Pyrus kawakami
Authors: Elam Pamela M. , Holmes Keith
Published: May 2022

Ornamental pears are extensively planted within the urban forest. In many climate zones, they become heavily infected with the bacterial disease, fireblight (Erwinia amylovora), which causes severe branch dieback and can kill young trees. This disease is also very serious in nursery stock,and trees are no longer grown in some areas. Theobjective of this study was to evaluate the usefulness of a temperature treatment threshold used in commercial pear production and to compare copper, streptomycin and aluminum tris for use in the prevention of fireblight on 5 gallon nursery stock ofPyrus kawakami. The temperature treatmect threshold is based on daily mean temperatures. In this study, it was found that the best preventative material was copper, followed by aluminum tris. All three compounds provided high degree of control. The daily mean temperature treatment threshold for commercialpearproduction appears to be later than would be appropriate for nursery production.

Предварительная приработка как метод повышения стойкости и надежности инструмента экономически оправдана применительно к дорогостоящему инструменту, работа которых сопряжена с большими материально-техническими затратами. К таким инструментам можно отнести фасонные, зуборезные, шлице обрабатывающие инструменты и другие. Годовые затраты на эксплуатацию данной группы инструментов зачастую превышают расходы, связанные с обслуживанием самого станка.Многофакторность процесса износа режущего инструмента является основной причиной, затрудняющей строгое математическое описание этого явления, поэтому методика исследования предусматривала сведение нежелательного фактора к минимуму и усиления интересующего. Это достигалось путем многократных повторений одной и той же серии опытов с соответствующим подсчетом критериев адекватности, либо проведением лабораторных опытов при варьировании одним или двумя факторами процесса при строгом соблюдении постоянства остальных. В данной статье приводятся результаты исследование влияние твердости обрабатываемого материала на оптимальную скорость предварительной приработки. Установлено, что эффективность предварительной приработки режущего инструмента можно повысить, если использовать в качестве приработочного материала стали с повышенной твердостью. Исследование выполнено в рамках грантового проекта БВ-Атех-2018-374 «Усовершенствование технологии производства зубчатых колёс в условиях Республики Узбекистан».

Задачами исследования являлось: проведение гидравлического и теплотехнического расчета системы охлаждения торцевых уплотнений насоса; разработка рекомендации по подбору основных узлов и их обвязки в системе охлаждения. В результате анализа причин возникновения неисправности одного из торцевых уплотнений установлено, что насос был подключен к цеховой системе охлаждения с выполнением требований по обеспечению подачи и давления в рекомендуемом изготовителем (согласно требованиям чертежа) диапазоне. Подключенная система охлаждения обеспечивала подачу охлаждающей жидкости (раствор этиленгликоля) с подачей 8 л/мин. и давлением 0,4 Мпа (4атм.). Однако, проработав не более 10 мин. его пришлось остановить по причине утечки перегоняемого сжиженного газа через одно из торцевых уплотнений. После снятия поврежденного уплотнения установлено, что оно представляет собой сдвоенное торцевое, выполненное по схеме «спина к спине», т.е. двух одинарных, расположенных противоположно друг к другу. Такая схема установки требует других технических требовании по величине давления охлаждающей жидкости, выполняющей одновременно функцию затворной, т.е., запирающей камеру уплотнения. Для такого типа уплотнений давление должна быть выше давления насоса на 0,1–0,15 МПа, т.е. для рассматриваемого насоса 4 МПа + (0,1–0,15) МПа. Таким образом, создаваемое системой охлаждения давление 0,4 МПа оказалось не достаточным, и в течении короткого периода работы насоса привело к выходу из строя уплотнения.

Предлагается вероятностная модель технико-экономической эффективности применения экспертизы, как действенного аппарата предиктивного оценивания функционального качества различных объектов. Показана положительная экономическая роль экспертизы в условиях неопределенности ранних этапов их жизненного цикла, например, при выборе потенциально результативной инновации и/или при разработке проектов систем энерго-, теплоснабжения. Верификационно-определяющее значение для принятия соответствующих управленческих решений имеет институт экспертизы, как действенный фильтр качества объекта анализа (ОА) на ключевых, особенно ранних этапах их жизненного цикла (ЖЦ). Поэтому вероятностный анализ технико-экономической эффективности данного института, как структурного элемента ЖЦ самых различных ОА, представляет собой важный прикладной аспект вариативно-отраслевой предиктивной квалиметрии основных технологий жизнедеятельности и жизнеобеспечения, к которым относится сфера тепло-, водо- и энергоснабжения различных потребителей. Намечены пути совершенствования предлагаемой модели, в частности, за счет учета в её структуре функционально-значимого масштабного фактора.
ŞANLIURFA MÜZESİ’NDEN UZANAN SYMPOSİAST TİPİNDE İKİ ADET PİŞMİŞ TOPRAK FİGÜRİNİN İKONOGRAFİSİ

Bu makalede Şanlıurfa Müzesi'nde korunan uzanan symposiast tipinde iki pişmiş toprak figürin ele alınmaktadır. Figürinler makale içinde Figürin 1 ve Figürin 2 olarak adlandırılmış olup özellikle ikonografik açıdan değerlendirilmiştir. Figürin 1 sol yanına uzanmış, bir elinde çiçek çelengi diğer elinde olasılıkla bir içki kabı tutmaktadır. Bir klinede uzanmış olan Figürin 2'nin elindeki nesneler aşınma sebebiyle anlaşılamamaktadır. Ancak kolların konumunun Figürin 1 ile aynı olması sebebiyle benzer ikonografiye sahip olduğunu düşünüyoruz. Bu tipte figürinler MÖ VI. yy.dan Hellenistik Dönem içlerine kadar Akdeniz Havzası'nın batısındaki Yunan etki alanında görülürken Hellenistik Dönem'den itibaren Mezopotamya’da görülmeye başlar. Benzerlerini yakındaki Zeugma'da bulduğumuz figürinlerin Yunan örneklerinden bilinmeyen bir ikonografiye sahip oldukları anlaşılmıştır. Figürinlerin elinde bulunan ve ölü kültü ile ilgili özel bir anlama sahip olan çiçek çelengi, tipin mezar ikonografisi ile ilgili anlama sahip olduğu yönündeki düşünceyi güçlendirmektedir. Bu makale ile figürinlerin tanıtılarak repertuvara kazandırılması ve gerek aynı tipteki figürinlerin gerekse tipin betimlendiği diğer eserlerin ikonografisine katkıda bulunmak amaçlanmıştır.

Objectives: The objectives of the study were to examine the relationship between symptoms of body dysmorphic disorder (body image) and personality traits: neuroticism, conscientiousness, extraversion, agreeableness, and openness to new experiences as well as the mediating role of perfectionism on the relationship between personality traits and body image in people undergoing cosmetic surgery. Methods: Results: The results of hierarchical regression analysis and mediation analysis showed that perfectionism has been shown to play a mediating role in the relationship between personality traits and body image. Conclusions: This research opens new directions for the study of psychological variables in cosmetic surgery and is also the first research in our area on the relationship between body image and personality traits. Because our sample is made up of participants who have had different surgical treatments, and given the huge increase in cosmetic surgery, a fuller understanding of personality influences can also allow surgeons to more accurately assess patients ‘suitability for surgery. It can also lead to a better understanding of the psychological aspects of cosmetic surgery and strengthen the foundation for promoting a healthier body image.

Authors: Pérez-Martínez Carlos , Vargas-Díaz Irma Beatríz , Palacios-Galicia José Luis
Published: May 2022

Antecedentes. En 1986 Fowler et al., describieron un síndrome en mujeres jóvenes con retención urinaria inexplicable asociado a esfínter uretral externo con escasa relajación. Estudios electromiográficos mostraron patrón anormal de actividad del esfínter en mujeres con síndrome de Fowler, sugiriendo que la retención es debida a propagación efáptica de los impulsos entre sus fibras musculares. Este síndrome es poco conocido y subdiagnosticado.
Objetivo. Conocer las características miccionales y la uroflujometría de mujeres con síndrome de Fowler, atendidas en el Centro de Urología Avanzada CURA de Delicias, Chihuahua, entre enero 2018 y enero 2021.
Materiales y métodos. Se revisaron expedientes de pacientes que acudieron y que fueron diagnosticadas como síndrome de Fowler. Se analizó las características demográficas, tiempo de evolución, principales síntomas, residuo post micción, diario vesical y uroflujometría con EMG de superficie.
Resultados. Se encontraron diez mujeres con síndrome de Fowler, con antecedentes de retención aguda de orina (RAO). La media de edad fue de 41.4±17.51 años y la media del tiempo de evolución del síndrome fue de 31.2±23.46 meses. La media de la frecuencia urinaria fue 14.2±4.75 micciones/24h, la media del Qmax fue 22.74±11.49 cc/s, la media del volumen miccional fue 198.30±89.54cc y la media de orina residual fue 231.5±86.12 cc. Todas las pacientes mostraron trazo de EMG con un patrón de hipertonía y falta de relajación.
Conclusiones. El síndrome de Fowler presenta un cuadro clínico que exhibe retención urinaria crónica con infecciones urinarias repetitivas, sin obstrucción infravesical. Su diagnóstico es posible por urodinámia no invasiva como la uroflujometría con EMG de superficie y evaluación del volumen post micción.

Application of Magnetoelectropolishing on the Oxidation Resistance Improvement of Stainless Steel Cladding in High-Temperature Water

Published: May 2022

Mechanical polishing (MP), electropolishing (EP), and magnetoelectropolishing (MEP) were applied on 308L stainless steel (SS) weld cladding. The surface characteristics after surface treatment and the oxides after immersion in the primary water of a pressurized water reactor were studied. XPS results showed that the passive film of surface-treated MEP 308L SS had higher Cr/(Ni+Fe) than MP and EP 308L SS, and reported surface-treated MEP 316L SS. Transmission electron microscopy results showed that duplex-layer oxide films consisted of Fe-rich spinel outer crystals and Cr-rich inner layers were formed on all surface-treated 308L SS cladding after immersion. The inner oxide layers on austenite were Cr-rich spinel dominant oxides and much thicker than the chromia-dominant oxides on ferrite. MEP decreased the inner oxide layer thickness on austenite of oxidized 308L SS. The oxidation resistance of the ferrite matrix with higher Cr content was not obviously impacted by surface treatment. A higher Cr/(Ni+Fe) in the preformed passive film on the austenite was mainly responsible for the better oxidation resistance of MEP 308L SS cladding. The improvement of oxidation resistance by MEP on dual-phase 308L SS cladding was different from that on single-phase 316L SS, suggesting that a local heterogeneous passive film on surface-treated MEP 308L SS was more likely degraded to a duplex-layer oxide film compared to the single-layer one on MEP 316L SS.
