The Relationship Between Frailty and Psychosocial Adjustment in Older Adults with COPD
Get PDFObjective: Frailty in older adults can manifest through various symptoms; reduced oxygen capacity is one of its prominent indicators. As individuals age, the prevalence of chronic obstructive pulmonary disease (COPD), a condition characterized by diminished oxygenation, also tends to increase. COPD and frailty can cause psychosocial adjustment difficulties. The study investigated the relationship between frailty and psychosocial adjustment in older adults with COPD. Materials and Methods: This descriptive-correlational study was conducted with 137 older patients who met the inclusion criteria. Data were collected using a patient identification form, the Psychosocial Adjustment to Illness Scale-self report (PAIS-SR), and the Edmonton Frail Scale (EFS). Results: Participants had a mean PAIS-SR score of 54.37 +/- 12.91. They had a mean EFS score of 6.79 +/- 3.83. Age and COPD stage affected their median PAIS-SR scores (p<0.05). Age, education, occupation, and hospitalization also affected their EFS scores (p<0.05). There is a negative correlation between frailty and psychosocial adjustment. Moreover, the COPD stage and frailty are associated with psychosocial adjustment. Conclusion: The frailer the older COPD patients are, the lower their psychosocial adjustment. Poor psychosocial adjustment is associated with COPD stages and frailty. Age, education, hospitalization, and psychosocial adjustment are predictors of frailty. Older COPD patients with low education levels, advanced disease stages, and frequent hospitalizations should be assessed for frailty and psychosocial adaptation. Evaluating patients may help us detect frail patients with low adaptation levels. In that way, we can meet patients' monitoring and care needs in the early period
The foreign operation authority of the National Intelligence Agency in the transformation of Turkish foreign policy
Get PDFTürkiye'nin ulusal güvenlik stratejilerinde kritik bir yere sahip olan MİT, 1965 yılında Milli Emniyet Hizmeti (MEH) yerine kurulmuş ve kuruluşundan itibaren hem iç hem de dış güvenlik politikalarının temel bir unsuru olmuştur. Soğuk Savaş sonrası dönemde MİT, artan uluslararası tehditler ve değişen güvenlik dinamikleri doğrultusunda kapsamlı bir dönüşüm sürecine girmiştir. Özellikle 2002 sonrasında, operasyonel kapasitesi artırılarak uluslararası arenada daha etkin bir konuma gelmiştir. Bu çalışma, Milli İstihbarat Teşkilatı'nın (MİT) dış operasyon yetkisinin Türk dış politikasının dönüşümündeki etkilerini incelemektedir. Tezde, MİT'in tarihsel gelişimi, 2002 sonrası dönüşüm süreci ve dış operasyon yetkilerinin hukuki dayanakları detaylı bir şekilde ele alınmıştır. Bu kapsamda, MİT'in Suriye, Irak ve Libya gibi bölgelerde gerçekleştirdiği dış operasyonlar incelenmiş, bu faaliyetlerin Türkiye'nin bölgesel ve uluslararası rolüne katkıları değerlendirilmiştir. MİT'in dönüşümü, Türkiye'nin dış politikada daha proaktif, güvenlik odaklı bir yaklaşım benimsemesine olanak sağlamış, terörle mücadeleden uluslararası kriz yönetimine kadar birçok alanda stratejik bir araç olarak kullanılmıştır. Elde edilen bulgular, MİT'in dış operasyon yetkilerinin, Türk dış politikasının dönüşümünde ve ulusal çıkarların korunmasında merkezi bir rol oynadığını göstermektedir. Bu çalışma, Türk dış politikasındaki değişim süreçlerini anlamak ve güvenlik stratejileri ile istihbarat faaliyetlerinin uluslararası ilişkilerdeki yerini değerlendirmek adına literatüre önemli katkılar sağlamaktadır.MİT, which plays a critical role in Turkey's national security strategies, was established in 1965, replacing the National Security Service (MEH). Since its inception, MİT has been a key component of both domestic and foreign security policies. In the post-Cold War era, MİT underwent a comprehensive transformation in response to increasing international threats and shifting security dynamics. Particularly after 2002, its operational capacity was enhanced, enabling it to assume a more active role on the international stage. The thesis delves into MİT's historical development, the transformation process after 2002, and the legal basis of its foreign operation authority. In this context, the study analyzes MİT's foreign operations in regions such as Syria, Iraq, and Libya, and evaluates the contributions of these activities to Turkey's regional and international role. MİT's transformation has allowed Turkey to adopt a more proactive and security-oriented approach in foreign policy, using intelligence activities as a strategic tool in areas ranging from counter-terrorism to international crisis management. This study examines the impact of the National Intelligence Organization's (MİT) foreign operation authority on the transformation of Turkish foreign policy. The findings indicate that MİT's foreign operation authority plays a central role in the transformation of Turkish foreign policy and the protection of national interests. This study provides significant contributions to the literature by enhancing the understanding of the transformation processes in Turkish foreign policy and assessing the place of security strategies and intelligence activities in international relations
Sağlık Çalışanlarının Motivasyonlarının İç Girişimcilikleri Üzerine Etkisi
Get PDFBu makalenin temel amacı, sağlık çalışanlarının motivasyonunun iç girişimcilikleri üzerindeki etkisini incelemektir. Bu amaca ulaşmak için nicel araştırma yöntemlerinden faydalanılmıştır. Türkiye’deki sağlık çalışanları olarak belirlenen evrenden kolayda örneklem yöntemi ile belirlenen çalışanlara dijital araçlarla anket formu gönderilmiş ve 360 anket formundan sağlanan veriler faktör analizi, normallik testi, regresyon ve korelasyon analizleri için kullanılmıştır. Yapılan faktör analizi sonucunda, çalışan motivasyonu üç faktör (dışsal motivasyon, algısal içsel ve ilişkisel içsel motivasyon), iç girişimcilik ise iki faktör (kurumsal ve bağımsız) altında gruplandırılmıştır. Korelasyon analizi bulgularına göre kurumsal iç girişimcilik ile motivasyonun tüm alt boyutları arasında orta düzeyde; bağımsız iç girişimciliğin ise düşük seviyede olumlu yönlü ilişkisi olduğu belirlenmiştir. Regresyon analizi sonucunda, çalışan motivasyonunun kurumsal iç girişimcilik üzerinde orta seviyede pozitif yönlü ve anlamlı etkisi olduğu saptanmıştır. Ayrıca çalışan motivasyonunun bağımsız iç girişimcilik üzerinde de düşük seviyede pozitif yönlü ve anlamlı etkisi olduğu da saptanmıştır. Çalışmanın sonuçlarına göre, çalışanların motivasyonlarının arttırılması, iç girişimciliklerini olumlu yönde etkileyecektir. Motive edici faktörlerin (mali kazanç, uygun çalışma ortamı, sağlık ekipmanı, tesis ve malzemelerin yeterliliği, yöneticilerin yapıcı davranışları, yönetimin ve personelin takdiri, yükselme ve uzmanlaşma imkanları) iyileştirilmesi, iç girişimciliğin de desteklenmesini sağlayacaktır
Tempered fractional version of trapezoid-type inequalities
Get PDFIn this article, trapezoid-type inequalities are proved by means of convex functions according to tempered fractional integral operators. The resulting trapezoid-type inequalities generalize several studies on this subject, including those involving Riemann-Liouville fractional integrals. To obtain these types of inequalities, we utilize the H & ouml;lder and power-mean inequalities. Finally, new results are obtained through specific parameter choices
Thermal design for a communications satellite payload module
Get PDFSatellite design and manufacturing studies have become crucial due to their exposure to extreme thermal conditions in outer space. Thermal management systems are necessary to maintain acceptable temperatures for equipment on satellites' structural panels. Accurate modeling, simulation, and testing are necessary to handle high-gradient temperature cycles, considering worst-case scenarios. The study aimed to design, model, and simulate a geostationary communication satellite using finite element method-based software, analyzing thermal modeling, and extraterrestrial satellites. The literature on controlling satellite temperature is limited, with most studies on cube and nano satellites. No scholarly work combines geosynchronous satellite thermal modeling with finite element analysis, which is crucial for understanding satellite thermal dynamics and solving structural and thermal problems in satellite design. A heat pipe network and MLI are placed on the panel, ensuring a homogeneous temperature distribution. In the worst-case scenario, a 2.8 m2 radiator area is used to eliminate heat dissipation from equipment. Analytical investigation is conducted to assess heat rejection capabilities of payload panels, followed by creation and implementation of reduced thermal mathematical models using commercial software. The worst hot-case analysis shows all equipment remains below upper-temperature limits, with heat pipes preventing excessive hot areas. The worst cold-case analysis requires a heater power of 480 W, with a 50% duty ratio aiming for 960 W. The FEM analysis reveals a duty ratio of 55% for panel heaters. Finally, the thermal design of the satellite can be used to maintain the equipment within its temperature limits.European Union [101130406]UKRI Engineering and Physical Sciences Research Council [EP/Y036662/1]The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: The last author, Ahmet Selim Dalk & imath;l & imath;cx would like to acknowledge the support from by European Union's Research and Innovation Program Horizon Europe under the Marie Sk1odowska-Curie grant agreement (No. 101130406) and UKRI Engineering and Physical Sciences Research Council (EP/Y036662/1)
Efficiency assessment and ses applicability analysis in energy intensive processes in the chemical industry
No full textKimya sektörü, yüksek ısı ve basınç gerektiren prosesler ile sürekli çalışan sistemleri nedeniyle yoğun enerji tüketimine sahip endüstriyel alanlar arasında yer almaktadır. Bu durum hem üretim maliyetlerini yukarı çekmekte hem de fosil yakıt kullanımına bağlı olarak sera gazı emisyonlarının artmasına yol açmaktadır. Yenilenebilir enerji kaynaklarının yaygınlaştırılması ve enerji verimliliği uygulamalarının hayata geçirilmesi, kimya tesislerinde hem ekonomik hem de çevresel açıdan kritik bir gereklilik haline gelmiştir. Enerji etüdü, mevcut tüketim noktalarının ve proseslerin detaylı incelenmesi sayesinde tesis içindeki enerji kayıplarını ve iyileştirme fırsatlarını belirlemeyi amaçlar. Bununla birlikte "enerji yoğunluğu" göstergesi, üretilen her birim ürün başına düşen enerji miktarını ortaya koyarak karşılaştırmalı performans izleme ve hedef belirleme sürecine temel oluşturur. Zaman serisi analizi yöntemlerinden özellikle ARIMA modelleri, geçmiş yıllara ait tüketim verileri üzerinden geleceğe yönelik güvenilir tahminler sunarak stratejik planlama ve bütçe optimizasyonunu kolaylaştırır. Güneş enerjisi santrali (GES) kurulumu ise kimya tesislerinde fosil yakıtlara bağımlılığı azaltarak enerji maliyetlerinde uzun vadeli düşüş sağlar ve karbon ayak izinin sınırlandırılmasına katkıda bulunur. Güneş panellerinin maliyetlerinin son yıllarda kaydettiği azalma, yatırım geri dönüş sürelerini kısaltmakta; devlet teşvik ve destek mekanizmaları da fizibilite çalışmalarını cazip kılmaktadır. Bu çalışmada, kimya sektörünün enerji verimliliği ihtiyaçları doğrultusunda önce enerji etüdü ve yoğunluk analizi yapılmış, ardından ARIMA modeli kullanılarak gelecek tüketim öngörüleri elde edilmiştir. Elde edilen veriler ışığında, tesise uygun kapasitede bir GES yatırımının teknik ve ekonomik yaşama dâhil edilme potansiyeli detaylı olarak değerlendirilmiştir.The chemical industry ranks among the most energy intensive sectors due to its reliance on high temperature, high pressure processes and continuous operation of complex units. This intensive energy use drives up production costs and contributes significantly to greenhouse gas emissions when fossil fuels are the primary energy source. Consequently, the adoption of renewable energy solutions and the implementation of energy efficiency measures have become both an economic imperative and an environmental necessity for modern chemical plants. An energy audit systematically examines existing consumption points and process streams to identify losses and opportunities for improvement. Complementing this, the energy intensity metric—expressed as energy consumed per unit of product—provides a benchmark for performance tracking and target setting. Time series forecasting, particularly using ARIMA models, leverages historical consumption data to generate reliable projections of future energy needs, thereby supporting strategic planning and budget optimization. Integrating a solar photovoltaic (PV) system offers a pathway to reduce dependence on fossil fuels, lower long term energy expenditures, and curb the facility's carbon footprint. Recent declines in PV module costs and the availability of government incentives have shortened payback periods and enhanced project viability. In this study, a comprehensive energy audit and energy intensity analysis of a chemical manufacturing plant's five year consumption data are first conducted. Next, ARIMA based forecasts inform the sizing and financial evaluation of a prospective solar PV installation, assessing its technical feasibility and economic benefits

Psychometric evaluation of the birth participation scale for fathers (BPS-F): a methodological study
Get PDFBackgroundThe participation of fathers in childbirth contributes primarily to the improvement of maternal and infant health and, consequently, to public health. To increase the participation of expectant fathers in childbirth, an appropriate screening tool is needed. This study was conducted to evaluate the psychometric properties of the Birth Participation Scale developed for expectant fathers.MethodsThe research involved a total of 250 expectant fathers who submitted applications to the Gynecology and Obstetrics Polyclinic of a university hospital. After translating the scale into a methodological and cross-sectional investigation, psychometric properties were evaluated. The validity of the scale was assessed by evaluating the content, construct, and face validity. Cronbach's alpha, McDonald's Omega, Spearman-Brown split-half and test-retest reliability coefficients were calculated to determine the item's reliability.ResultsThe average content validity index (CVI) values for relevance, clarity, and simplicity were found to be 0.99 for each. The impact score of the items was 1.5 and above. A factor structure with 17 items, and 3 sub-dimensions was obtained through Exploratory Factor Analysis. The factor loadings of the items ranged between 0.55 and 0.85. The validity of this structure was assessed by Confirmatory Factor Analysis and the model fit indices were acceptable or good fit. The reliability coefficients for Cronbach's alpha, McDonald's Omega, and Spearman-Brown split half were 0.89, 0.92, and 0.81, respectively. Moreover, the test-retest correlation was 0.96.ConclusionsThe Birth Participation Scale for Fathers has a suitable validity and reliability for assessing fathers' participation in birth. It is a simple reporting tool that healthcare professionals in Turkey can easily implement.Napier University's School of Nursing, MidwiferyWe would like to convey our sincere appreciation to every participant who assisted us in conducting this research.

Prioritization of Industrial Symbiosis Enablers Using a Hesitant Fuzzy SWARA Approach
Get PDFIndustrial symbiosis (IS), a crucial tool for reducing industrial waste, preventing pollution, and enhancing resource efficiency, is emerging as one of the sustainable approaches. IS is a network structure in which independent industrial enterprises cooperate and use the waste or by-products of one as raw material for the other. This synergistic network structure can help companies reduce costs, boost efficiency, and lessen negative environmental impacts. However, successful IS implementation relies on key enabling factors facilitating collaboration and ensuring mutual benefits among participants. This study focuses on Türkiye, where the development of IS networks holds significant potential due to its industrial diversity and growing emphasis on sustainability. It aims to rank the critical enabling factors in fostering these networks. To achieve this aim, Stepwise Weight Assessment Ratio Analysis (SWARA), a subjective multi-criteria decision-making (MCDM) technique that systematically evaluates and ranks criteria based on expert judgments, was employed. This approach was integrated with hesitant fuzzy sets to account for uncertainty and hesitation in expert opinions, ensuring a more robust assessment of the enabling factors. In the present study, a comprehensive literature review and expert opinions were employed to identify 23 sub-enablers falling under five main dimensions. The hesitant fuzzy SWARA method was then applied to calculate their importance weights. The results of the study indicate that the five most critical sub-enablers are, in descending order of importance: "reduction of raw material costs," "interest and support from top management," "reduction of waste disposal costs," "geographical proximity," and "openness to new business ideas.
