The Effect of Inclusive Leadership on the Work Engagement: An Empirical Study from Turkey
Hü,seyin ASLAN,İ,brahim Sani MERT,Cem Ş,EN 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.11
Motivating employee work engagement, which has emerged as one of the most significant drivers of high performance and achievement in today’s dynamic environment, has become essential in gaining a sustainable competitive advantage. As widely known, leadership is a primary factor affecting work engagement. This is also directly related to a specific style of leadership exercised. Leadership styles affect the work engagement levels of the employees. The distracting nature of leadership type can have adverse impacts on individuals’ behaviors. To provide a comprehensive understanding of the phenomenon, this article draws on social interaction theory and social exchange theory to investigate the potential effects of inclusive leadership on work engagement within the workplace, and the mediating role of psychological safety on the relationship between inclusive leadership and the work engagement. Here, psychological safety is needed by employees to avoid and manage negative feelings. SPSS and AMOS software was applied to survey data obtained from (n = 373) employees. Results revealed that inclusive leadership is a strong predictor for work engagement, and psychological safety partially mediates the link between inclusive leadership and work engagement. Implications for theory and practice alongside limitations are discussed.
Phonon–photon-assisted tunnelling through an Aharonov–Bohm ring
Shin, Dongkwan,Oymak, H?seyin,Hong, Jongbae IOP Pub 2007 Journal of Physics, Condensed Matter Vol.19 No.22
<P>We model a four-site tight-binding Aharonov–Bohm?(AB) ring whose sites house dispersionless Einstein phonons. The resonant tunnelling of an electron through the?AB ring in the presence of a time-periodic magnetic flux which threads the ring is investigated. The Floquet scattering approach is followed within the electron–phonon Fock space. The Ricatti matrix method, a nonperturbative pruning technique, is utilized to extract the transmission properties of the system from the time-dependent Schr?dinger equation. We observe additional satellite peaks in the total transmission graphs representing the photon-assisted tunnelling, as well as side resonances due to the phonon-assisted tunnelling. There happen to exist unusually stiff main transmission peaks that are not disturbed by the strong time-periodic magnetic flux, a finding attributed to the geometric characteristics of the?AB ring.</P>

Exopolysaccharide producing starter cultures enable manufacturing ‘‘clean labeled’’ foods with improved textural and nutritional properties. The structural and technological analyses were performed on the ropy exopolysaccharides of six Lactobacillus plantarum. The incubation temperature, time and pH affected the exopolysaccharide production and high exopolysaccharide was produced in the presence of sucrose and maltose. The viscosity of exopolysaccharide was high at acidic conditions except PFC311E that showed viscous at neutral pH. Lactobacillus plantarum strains produced between 120 and 400 mg/L exopolysaccharide in which the highest was observed at L. plantarum PFC311. Exoploysaccharides were degraded over 300 』C except PFC311E that degraded at 295.7 』C. The NMR analyses revealed that the exopolysaccharides were synthesized by a1-6, a1-3 and a1-4 bonds with glucose, galactose and fructose moieties. In conclusion, L. plantarum PFC311 produced ropy exopolysaccharide with different structural, rheological and thermal properties and reveals potential to be used in food industry.
A case of immune-mediated type 1 diabetes mellitus due to congenital rubella ınfection
Hüseyin Anıl Korkmaz,Çağatay Ermiş 대한소아내분비학회 2019 Annals of Pediatirc Endocrinology & Metabolism Vol.24 No.1
Congenital rubella infection is a transplacental infection that can cause intrauterine growth retardation, cataracts, patent ductus arteriosus, hearing loss, microcephaly, thrombocytopenia, and severe fetal injury. It has been shown that type 1 diabetes mellitus develops in 12%–20% of patients with congenital rubella infection, and disorders in the oral glucose tolerance test is observed in 40% of patients. No biochemical or serological markers exist which could indicate that type 1 diabetes was caused by a congenital rubella infection. We report a 13-year-old male patient who was admitted to our hospital with complaints of new-onset polyuria, polydipsia, urination, and weight loss. In addition, he was found to have neurosensory hearing loss, patent ductus arteriosus, and microcephaly. Immunemediated type 1 diabetes mellitus was considered due to the fact that the autoantibodies of diabetes mellitus were positive.

Monitoring large structures is a significant issue involving public health on which new studies are constantly carried out. Although the Global Navigation Satellite System (GNSS) is the most preferable method for measuring structural displacements, total stations, one of the classical geodetic instruments, are the first devices that come to mind in cases that require complementary usage and auxiliary measurement methods. In this study, the relative displacements of the structural movements of a tower were determined using robotic total stations (RTS) and GNSS. Two GNSS receivers and two RTS observations were carried out simultaneously for 10 hours under normal weather conditions. The spectral analysis of the GNSS data was performed using fast Fourier transform (FFT), and while the dominant modal frequencies were determined, the total station data were balanced with the least-squares technique, and the position and position errors were calculated for each measurement epoch. It has been observed that low-frequency structural movements can be determined by both methods. This result shows that total station measurements are a helpful alternative method for monitoring large structures in situations where measurements are not possible due to the basic handicaps of GNSS or where it is necessary to determine displacements with short observations.
Recurrent and Massive Life Threatening Epistaxis due to Nasal Heroin Usage
Hüseyin Yaman,Yusuf Aydın,Süleyman Yılmaz,Elif Önder,Ender Güçlüm,Özcan Öztürk 대한이비인후과학회 2011 Clinical and Experimental Otorhinolaryngology Vol.4 No.3
Epistaxis, active bleeding from the nose, is a common ear nose and throat emergency, and can be severe or even fatal. We report a severe life threatening recurrent massive nasal bleeding caused by intranasal heroin use that has not hitherto been reported in the English literature. A 24-year-old male who took heroin several times nasally presented with massive nasal bleeding. A blood transfusion and an operation to halt nasal bleeding were required. The patient did not experience a bleeding attack 2 months following cessation of nasal heroin use.

Purpose: In this study, we evaluated the effect of preputial type on bacterial colonization and wound healing in boys undergoing circumcision. Materials and Methods: This study consisted of 78 boys consecutively admitted to our clinic for circumcision between 2009 and 2011. Preputial status was classified into five types on the basis of preputial retractability. One sterile culture swab was swept circumferentially once around the surface of the glans starting just proximal to the urethral meatus. Three weeks following circumcision, control swabs from the same regions of the same patients were taken and inoculated. Thus, the same patients formed the control group. Patients were evaluated on days 1 and 7 after the operation to assess whether the preputial type affected healing. Results: The mean age of the children was 46.3 months. In our study, the growth rate was 71.8% in pre-circumcision patients, whereas the rate was 10.25% in the post-circumcision group. Types 1, 2, 3, 4, and 5 had 100%, 93.8%, 71.4%, 44.4%, and 53.6% colonization, respectively. A significant difference was observed among these types in terms of colonization. The most common agent was Enterococcus species (33%). When postoperative patients were evaluated, all had local swelling and hyperemia on postoperative day 1, whereas there was a significant difference on day 7. Conclusions: There was a significant correlation between preputial type and bacterial colonization, and the preputial type affected post-circumcision wound healing. Practitioners should keep in mind that the healing period will be longer in patients with type 1, 2, and 3 preputium.

Frequency analysis of GPS data for structural health monitoring observations
Hüseyin Pehlivan 국제구조공학회 2018 Structural Engineering and Mechanics, An Int'l Jou Vol.66 No.2
In this study, low- and high-frequency structure behaviors were identified and a systematic analysis procedure was proposed using noisy GPS data from a 165-m-high tower in İstanbul, Turkey. The raw GPS data contained long- and short-periodic position changes and noisy signals at different frequencies. To extract the significant results from this complex dataset, the general structure and components of the GPS signal were modeled and analyzed in the time and frequency domains. Uncontrolled jumps and deviations involving the signal in the time domain were pre-filtered. Then, the signal was converted to the frequency domain after applying low- and high-pass filters, and the frequency and periodic component values were calculated. The spectrum of the tower motion obtained from the filtered GPS data had dominant peaks at a low frequency of 1.15572×10-4 Hz and a high frequency of 0.16624 Hz, consistent with two equivalent GPS datasets. Then, the signal was reconstructed using inverse Fourier transform with the dominant low frequency values to obtain filtered and interpretable clean signals. With the proposed sequence, processing of noisy data collected from the GPS receivers mounted very close to the structure is effective in revealing the basic behaviors and features of buildings.
