Abstract
Direct pulp capping is a procedure where materials are placed on exposed vital pulp tissue in order to stimulate reparative dentinogenesis and preserve pulp vitality. Carious pulp exposure and direct pulp capping are usually accompanied by pulp inflammation which can affect pro- and anti-oxidative systems locally or systemically. Therefore, this study aimed to investigate the potential influence of direct capping of inflamed rat dental pulp with calcium hydroxide (CH) and mineral trioxide aggregate (MTA) on parameters of systemic oxidative status.
Dental pulps of the first maxillary molars of Albino rats (n=32) were exposed and capped with either CH (n=8), MTA (n=8) or were left untreated (n=8). Animals with healthy pulp were used as a healthy control (n=8). After four weeks, animals were euthanized and blood samples were collected for biochemical analysis of parameters of systemic oxidative stress by spectrophotometric method.
Untreated control had the significantly higher (p <0.05) values of pro-oxidative parameters and lower (p <0.05) values of anti-oxidative parameters (superoxide dismutase and reduced glutathione) compared to healthy control. CH and MTA groups showed reduced values of pro-oxidative parameters compared to untreated control and values of anti-oxidative parameters comparable to healthy control.
Pulp exposure led to disbalance in systemic oxidative parameters while direct pulp capping with calcium hydroxide and mineral trioxide aggregate restored the levels of systemic oxidative parameters to that of animals with healthy dental pulp. These results indicate the importance of direct pulp capping and the potential influence of untreated inflamed pulp on systemic health.

This study aims to analyze the influence of bureaucratic leadership and organizational culture in public service on workforce agility mediated by psychological empowerment in East Kalimantan. This is an explanatory survey of local government organizations/LGOs in East Kalimantan with an observation unit, consisting of 238 employees who were selected randomly. Data analysis was then carried out using the covariant SEM procedure. The results showed that workforce agility was influenced by leadership and organizational culture. Therefore, leaders who are able to maintain balance in local political dynamics, administrative demands, and running strategy execution are needed. This is because they can ensure the readiness of subordinates to participate in acceleration. Additionally, the organizational culture ensures the orientation of employees to workforce agility through an effective empowerment process. Psychological empowerment mediates the influence of bureaucratic leadership and organizational culture on workforce agility. Agility concept in the organization is one of the major focuses, and itsimplementation is a strategic and operational framework for public institutions. Integrating the idea of ​​agility, leadership, and workforce is a framework to design methods and taxonomies to set priorities for workforce agility in public institutions from a new public service perspective.

Published: January 2023

Pipe fittings are an important element of any pipeline network, ensuring stable and safe operation by regulating the flow of the working medium. To control the performance of pipeline valves, it is necessary to conduct various tests, the main ones of which are hydraulic and pneumatic. It is important to expand testing capabilities and reduce time costs. The purpose of this work is to combine hydraulic and pneumatic tests into one test complex, which will reduce the time of the test complex due to the absence of the need for reinstallation and reconfiguration. The subject of the study is the determination of the design, technical, and operational characteristics of such a stand, as well as the simulation of operating conditions to confirm its operability. During the development, methods of solid and surface modeling, the finite element method, and analytical calculation methods were used. The results of the stand design are presented, and the features of the process of its development are described, including the analysis of the stress-strain state and the analysis of reliability and durability indicators. The obtained values of the distribution of equivalent stresses, deformations, and displacements of the structure elements do not exceed the maximum allowable values and do not lead to destruction. The analysis shows that the developed stand has improved capabilities compared to those previously used. Doi: 10.28991/CEJ-2023-09-01-013 Full Text: PDF
The Influence of Moisture on the Frequency Spectrum of Time Varying Mass Engineering Structure
Authors: Tu Phung , Vimonsatit Vanissorn , Hansapinyo Chayanon 
Published: January 2023

The frequencies of time-varying mass systems have not been commonly studied in engineering structures as the rate of mass change is generally small compared to the mass of the overall structure. For silos of granular materials, the total mass of the stored granules can be relatively high compared to the mass of the silo structure. During the flow-in or flow-out of granules, the silo system behaves as a time-varying mass system. Minor changes to the moisture content ratio of the granules can cause their flow characteristics to change. The influence of the moisture content ratio of the granular material inside a cylindrical silo is investigated in this paper using Variational Mode Decomposition, Hilbert Transform, and Hilbert Marginal Spectrum processing methods. The results show that the amplitude and frequency of vibration vary with the change in the moisture content ratio of the stored materials and across different cycles, despite all influencing parameters being kept constant. Such variations in the response of the structure mean that the loads also vary according to the principles of engineering mechanics. The outcomes of this research can be further developed into a diagnostic tool to conditionally monitor the structural integrity of the overall silo structure and flow characteristics automatically.

Published: January 2023

The amount of rainfall can be used to estimate the runoff that enters a reservoir. Runoff is influenced by land use, and soil type greatly affects the amount of runoff that will occur. This study discusses the development of a hydrological model with the application of the Hydrologic Engineering Center (HEC-HMS) in the Karangmumus watershed using soil data that has been verified in the field and divided into soil zones based on soil permeability testing in the laboratory. With the help of Geographic Information System (GIS) and Geospatial Hydrological Model (HEC-GeoHMS) applications, it is possible to identify the flow of the Karangmumus watershed and the Lempake Dam in Kalimantan by simulating the rain runoff process. The hydrological model was developed in the HEC-HMS by recording daily rainfall events from 2009 to 2019. With a daily period, then, the zoning soil type data was entered based on the results of soil permeability testing with the help of the application of the soil conservation curve method (SCS-CN), then discharge transformation, and calculation of water loss, including routing with Muskingum and SCS-Hydrograph applications. Based on the distribution of the CN value, the theoretical runoff is calculated and then calibrated with the observed discharge in 2017 and 2018, and then validated with the observed discharge in 2019, showing good results with a coefficient of determination between 0.89 to 0.92.

Published: January 2023

Devletin kültür ve sanat politikalarının Halkevleri aracılığıyla programlı bir şekilde yürütüldüğü Erken Cumhuriyet döneminde (1923-1950), yeni rejimin ideolojisini anlatmak amacıyla sanatın gücünden yararlanılmış; sanatçılar, devrimi yansıtan görsellerle bu sürece yön vermede katkı sağlamışlardır. Özellikle, ülke çapında faaliyet gösteren Halkevleri tarafından çıkarılan dergiler, Cumhuriyet ideolojisinin ve devrim ilkelerinin yayılmasında etkili olmuşlardır. Yeni rejimin yazılı ve görsel sözcülüğünü üstlenen Ankara Halkevi dergisi Ülkü, Türk dili, devrimler, felsefe, tarih, edebiyat, müzik ve sanat politikaları gibi çeşitli alanlardaki yazılarının yanı sıra içerik ile uyumluluk gösteren kapak tasarımları açısından da önem arz etmektedir. Şubat 1933 ile Ağustos 1950 tarihleri arasında 272 sayı yayımlanan Ülkü dergisi kapaklarının bir kısmında tipografi, fotoğraf ve sanatçı çizimleri yer almıştır. 16 Aralık 1941- Ekim 1947 tarihleri arasına denk gelen ve bu çalışmaya konu edilen 89 kapağın büyük bir çoğunluğu Cumhuriyet döneminin öne çıkan sanatçıları tarafından tasarlanmıştır. Söz konusu kapaklarda yurt manzaraları, Anadolu insanının yaşantısı, folklorik özellikleri, köy ve köylüler, kadınlar, başkent Ankara ve çevresi, Cumhuriyet liderleri, milli bayramlar kutlamaları, anıt heykel uygulamaları, modern yaşam biçimleri ve mekânları gibi konular ele alınmıştır. Ülkü dergisiyle ilgili yapılmış çok sayıda çalışma olmakla birlikte, belirtilen tarih aralığında takip edilen 89 illüstrasyonlu kapak sayfasına, içerik ve tasarım odağında yaklaşan bir çalışmanın olmaması bu araştırmanın yapılma isteğini doğurmuştur. Bu makalede, Cumhuriyet’in yeni bir toplum yaratma tahayyülü ve yaşam pratiklerinin dergi kapaklarına nasıl yansıtıldığı ve sözel/yazınsal dildeki Cumhuriyet ideolojisi ve devrim ilkelerinin yine bu kapaklar yoluyla görsel dile nasıl tercüme edildiği ortaya konacaktır.

ABSTRACT
Background: Literature on the impact of patient-satisfaction metrics on nursing staff is scarce and limits nurses’ ability to understand the impact these metrics have on their daily practice.
Aim: The aim of this qualitative study is to explore nurses’ perceptions of patient satisfaction surveys on their daily practice when working with patients with acute neurological changes.
Method: A content analysis approach was used to analyze interviews with six neurosurgical nurses. The analysis was conducted throughout the interview and analysis process, and guided interviews and rigor processes.
Results: Among the surveyed nurses, there was unified agreement that the current tool for obtaining the metrics did not accurately reflect the performance of the registered nurse. Themes that emerged from interview analysis included “anxiety”, “frustration”, “uncertainty”, and “workarounds”. Interviews uncovered a disconnect between clinical nurses and leadership, as well as how feedback is presented to nurses by patients, which drove many of the themes listed above. The nurses felt that the metrics should not be linked to individual performance feedback.
Conclusion: Nurses report that patient satisfaction surveys do not represent an ideal metric for quality of nursing care and impact their daily practice negatively. These results could be applied to improving the registered nurse performance evaluation tools utilized in neurological units.
