A Comparative Analysis of the Change of Kula Traditional Turkish Housing Architecture in The Last 50 Years
Kula is a district rich in cultural values. There are many historical and traditional residences in this region. These historical structures have undergone great and different changes over time. It is aimed to determine the transformations related to facade, structural element, and interior use in traditional houses. In addition, by looking at the obtained data, namely the architectural changes, it was determined as a secondary purpose to make suggestions about conservation.
The study consists of a combination of two basic methods: literature research and field research. After determining the subject of the study, written sources related to the subject were searched and the research was supported by field studies. The method of the study is the comparison of the data obtained from the sources and the evidence in the field study. Findings were obtained by analyzing the detected differences. In the study, which was carried out with the comparative analysis method, the historical process was examined, and information, architectural drawings and photographs were obtained about the conditions of the buildings 50 years ago. For this reason, scope of the study consists of both the data obtained and the houses that provide both conditions depending on the availability of these data today. In this context, the study is limited to 14 traditional Turkish residences in the Kula site, from which both historical data and locations can be accessed.
In the studies carried out in the field of architectural restoration and conservation, the current situations are examined in the studies on conservation. However, in this study, not only the current situation of the buildings, but also the conditions of the previous years and even the comparison of the data was obtained. Although this study was carried out within the scope of Kula district, it gives an idea about the change and usage of interiors of the residences
Dosimetric phantom consistency of TMR-10 protocol in homogeneous and inhomogeneous regions in gamma knife radiosurgery planning
Introduction: The algorithms used in the GammaPlan treatment planning system are “Tissue Maximum Ratio (TMR) classical,”“TMR 10,” and “convolution” algorithms, respectively. In this study, the consistency of dosimetric measurements with the TMR 10 protocol used in SRC (stereotactic radiosurgery) planning in lesions located in homogeneous and inhomogeneous regions in different intracranial location scenarios was investigated. Methods: In this study, the accuracy of administration of multiple metastasis treatment on the Gamma Knife Perfexion device was investigated. Computed tomography was performed with 1 mm cross-section intervals of CIRS brand Atom randofantoma. Critical organs and three different brain metastases located in homogeneous and heterogeneous regions, which are not on the same plane with each other, were drawn on the phantom. Planned target volume (PTV) volumes were created without margining the drawn gross tumor volumes, and three separate plans were made for three different PTV volumes. All plans were calculated using the TMR 10 algorithm. Critical organ doses were kept below the brain-SRC criteria for all calculated plans. Gafchromic EBT-3 film was placed on the sections with the target volume drawn on the phantoms and irradiated (1600 cGy, 50% isodose area). Measurements were made three times. The measured film results and the doses calculated from the planning were compared with gamma index analysis for different tolerance values. Results: In our study, for three different lesions planned and irradiated with different gradient index values, a difference of 2.11–9.58% was observed between the values calculated with the TMR-10 protocol and the values obtained in the dosimet- ric measurement. A decrease in consistency was observed, especially in inhomogeneous region placements. Discussion and Conclusion: There may be inconsistency between the TMR-10 protocol and actual dosimetric measurements, especially around inhomogeneous intracranial structures. We hope that this inconsistency will decrease in the future with the developing dose calculation protocols
Solving Weighted Number of Operation Plus Processing Time Due-Date Assignment, Weighted Scheduling and Process Planning Integration Problem Using Genetic and Simulated Annealing Search Methods
Traditionally, the three important manufacturing functions, which are process planning, scheduling and due-date assignment, are performed separately and sequentially. For couple of decades, hundreds of studies are done on integrated process planning and scheduling problems and numerous researches are performed on scheduling with due date assignment problem, but unfortunately the integration of these three important functions are not adequately addressed. Here, the integration of these three important functions is studied by using genetic, random-genetic hybrid, simulated annealing, random-simulated annealing hybrid and random search techniques. As well, the importance of the integration of these three functions and the power of meta-heuristics and of hybrid heuristics are studied
The numerical and experimental analysis of forced convection on the surfaces of a rectangular box with heat generation
Paper presented at the 6th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 30 June - 2 July, 2008.The system development with experimental studies that is
accomplished by trial and error method is neither practical nor
economical since it is difficult and expensive. So that, creating
the mathematical model and determining the most appropriate
design data by using numerical solutions is a more effective
and cheaper approach for the system development. In this study
numerical and experimental analysis of forced convection heat
transfer from the horizontal and lateral surfaces of a 0.3m x
0.3m x 0.52m rectangular box in a 0.55m x 0.55m x 3m wind
tunnel, which is heated by a 0.5m length cylindrical 450 W
power source with a constant surface temperature of 200ºC,
was performed. The temperature distribution on all exterior
sides of rectangular box subjected to forced convection, were
calculated by finite volume numerical analysis and compared
with the results obtained from the experimental measurements.
The main objective of this study is to verify the mathematical
model which was constituted for the numerical solution. The
results obtained from the numerical analysis were
approximately similar to the ones obtained in experimental
analysis, so the mathematical model was verified.vk201
Exploring the clinical characteristics and etiological factors of comorbid major depressive disorder and social anxiety disorder
The comorbidity between the major depressive disorder (MDD) and the social anxiety disorder (SAD) is significantly prevalent, necessitating a nuanced understanding of their overlapping clinical characteristics and shared etiological factors, including inflammatory biomarkers. To address this, we conducted a cross-sectional study from December 2021 to June 2022, encompassing 204 outpatients diagnosed with MDD-SAD comorbidity. We employed various psychometric assessments, such as the Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Childhood Trauma Questionnaire (CTQ-28), Toronto Alexithymia Scale (TAS-20) and the Liebowitz Social Anxiety Scale (LSAS). Additionally, we analyzed inflammatory biomarkers including the neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte platelet ratio (NLPR), systemic inflammation index (SII), and the systemic inflammation response index (SIRI). Our findings accentuated that patients primarily diagnosed with MDD exhibited elevated levels of certain inflammatory biomarkers. They reported more severe and atypical depressive symptoms (75.7% vs 58.5%; P = 0.010) and had significantly higher CTQ-28 subscale scores (P < 0.05). Our study unveils a complex relationship between MDD and SAD, with significant disparities in the symptom severity and inflammatory biomarker levels, thereby establishing a compelling case for dual-diagnosis treatment approaches. It elucidates the critical role of inflammation in the comorbidity of MDD and SAD, marking a pioneering step towards more comprehensive and holistic patient care strategies. These insights could potentially revolutionize therapeutic approaches in psychiatric care, promising significantly improved outcomes through early detection and integrated intervention strategies
Bonding Effectiveness of Saliva-Contaminated Monolithic Zirconia Ceramics Using Different Decontamination Protocols
OBJECTIVE
This research study investigated the effect of new decontamination protocols on the bonding capacity of saliva-contaminated monolithic zirconia (MZ) ceramics cemented with two different monomer-containing self-adhesive resin cements.
MATERIALS AND METHODS
Standardized tooth preparations (4 mm. axial height) were performed for eighty human maxillary premolars under constant water cooling system. Eighty monolithic zirconia crowns (Whitepeaks Supreme Monolith) (n = 8/10 groups) were manufactured by CAD-CAM. Specimens were kept in the artificial saliva at pH = 7.3 for 1 minute at 37°C except control groups. The specimens have not been prealumina blasted and grouped according to cleaning methods and resin cements: control groups (C) (no saliva contamination + GPDM + 4-META (N) (CN) and 10-MDP (M) containing resin cement (CM), alumina blasted (AL) + GPDM + 4-META (ALN) and 10-MDP containing resin cement (ALM), zirconium oxide containing universal cleaning agent (IC) applied + GPDM + 4-META (N) (ICN) and 10-MDP containing resin cement (ICM), pumice (P) applied + GPDM + 4-META (PN) and 10-MDP containing resin cement (PM), and air-water spray (AW) applied + GPDM + 4-META (AWN) and 10-MDP containing resin cement (AWM)). Monobond Plus was applied to all surfaces for 40 seconds before cementation. The thermal cycle was applied at 5,000 cycles after cementation. The crowns were tested in tensile mode at a speed of 1 mm/min. The mode of failure was recorded. SEM examinations were carried out at different magnifications. Data were analyzed using rank-based Kruskal-Wallis and Mann-Whitney tests.
RESULTS
No significant differences were found between the surface treatments and between the two types of resin cements. Interaction effects between surface treatments and resin cements were found to be significant by two-way ANOVA analysis. ICM group resulted in significantly better bond strength results compared with CN. ICM was found to result in better bond strength results compared with PM. The combination of universal cleaning agent and 10-MDP containing resin cement had significantly the highest cementation bond strength values. The increasing order of mean tensile bond strength values of decontamination protocols was C < AW < P < AL < IC. The mean tensile bond strength of 10-MDP containing resin cement was slightly higher than GPDM + 4-META containing resin cement.
CONCLUSIONS
Universal cleaning agents can be preferred as an efficient cleaning method with 10-MDP-containing cement after saliva contamination for better adhesive bond strength of 4 mm crown preparation height of monolithic zirconia ceramics

Maternal Psychological Problems Associated with Neonatal Intensive Care Admission
Background.
Mothers of infants admitted to a neonatal
intensive care unit (NICU) are believed to have
heightened distress. The purpose of this paper was to determine depression and anxiety
symptoms and attachment style in NICU mothers.
Methods. The NICU group
consisted of mothers whose infants were admitted
to the NICU and the control group consisted of
mothers of healthy term infants. The
psychosocial assessments were done at the first
month. Results. The mean Edinburgh Postpartum Depression (EPDS) score of NICU
mothers was significantly higher than that of
the control group mothers (9.6 ± 5.6 versus 7.3 ± 4.9, P = .005). NICU mothers who had high EPDS (≥13) scores had significantly higher anxiety scores and insecure attachment style in comparison to the subgroup of NICU mothers who had low EPDS scores. Conclusion. Mothers of NICU babies had higher EPDS scores. Mothers who had higher EPDS scores had higher anxiety scores as well. These NICU mothers should receive appropriate counseling during the hospitalization of their babies
