Senay Ozgen,Saziye Sekerci,Recep Korkut,Tugba Karabiyik 한국원예학회 2012 Horticulture, Environment, and Biotechnology Vol.53 No.4

The vast majority of the tomato crop is harvested at mature green stage and ripened off of the plant for fresh market consumption. The other large amount of crop is harvested when the fruit has reached to fully mature red stage which is called “vine-ripened”. Here we attempt to answer and clarify if there is any difference between the antioxidant capacity of postharvest ripened and vine ripe tomatoes. Greenhouse grown tomatoes (cv. Newton)were harvested at four different ripening stages of unripe and vine ripe. Total phenolic (TP) contents and antioxidant capacity by the FRAP (ferric reducing antioxidant power) and TEAC (trolox equivalent antioxidant capacity) assays were performed on all ripening stages. Results of the present study demonstrated that tomato peel has significantly higher TP content and antioxidant capacity than the pulp tissues in all maturity stages tested. TP and antioxidant capacity of tomato fruits were affected during postharvest ripening process. If only pulp tissue considered, TAC of vine-ripened and postharvest ripened pink tomatoes has similar amount, but significantly higher content than mature green, breaker and turning maturity stages. If peel tissue measured, the mean separations identified three groups. Postharvest ripened mature green stage has the most TAC, followed by vine-ripened and pink stage. Postharvest breaker and turning stages have the least amount of TAC.

The impact of self-construal and self-concept clarity on socially motivated consumption: The moderating role of materialism

Senay Sabah 한국마케팅과학회 2017 마케팅과학연구 Vol.27 No.1

in order to measure the eff ect of two important variables for consumption. The fi rst one is the eff ect of the independent/ interdependent self-construal factors in addition to self-concept clarity. The second one is the intersection eff ect of these self-related concepts with materialism on socially motivated consumption. These hypotheses are tested using multiple regression analysis. Analyses are made based on a data sample of 230. It has been found that all of the expected relations, except the direct relation between selfconcept clarity and attitude towards diamond wedding ring, besides the moderating role of materialism between the interdependent selfconstrual and self-concept clarity and attitude towards diamond wedding ring, are signifi cant. However, it is seen that the sign of the relation between interdependent self-construal and attitude towards wedding ring was negative. The present paper argues that these contradictory results may be due to cultural factors.

<P><B>Abstract</B></P> <P>We analyzed the data consist of core digital images and X-rays, core-logs, LWD (logging-while-drilling), and sediment grain-size from the second Ulleung Basin Gas Hydrate Expedition (UBGH2) in the East Sea. Core digital images and X-rays were spliced as a complete composite core in meters below seafloor (mbsf) for five sites; UBGH2-1_1 (Hole D), 2_1 (B), 2_2 (B), 2-6 (B) and 2-10 (C–D), and were correlated with the core-log and LWD measurements showing that possible gas hydrate bearing layers are between the depths of about 60–180 mbsf at these sites. Bulk densities generally increase with depth from 1.3 to 2.0 g/cm<SUP>3</SUP> in LWD data, and from 1.1 to 1.8 g/cm<SUP>3</SUP> onboard which measured lower than in-situ. Gas hydrate bearing sediments respond with an increase of LWD densities (1.4–1.6 g/cm<SUP>3</SUP>) and a decrease in core-logs (1.1–1.4 g/cm<SUP>3</SUP>). P-wave velocity values of LWD increase (1400 to 1700 m/s) with depth for non-reservoirs, and are high (1500 and 2000 m/s) within the gas hydrate bearing intervals depending on the hydrate saturations.Resistivity values logged onboard range from less than 1.0 to over 10.0 Ω-m, while LWD records are around 1.0 Ω-m and between 5.0 and 30.0 Ω-m in background sediments and possible gas hydrate reservoirs, respectively. High resistivity values were observed (5.0–30.0 Ω-m) within coarse-grained turbidites (mean grain-size between 2.9 and 5.1 ϕ; laminated sandy mud or muddy sands). Medium resistivities were observed (5.0 Ω-m) within the silt-dominant hemi-pelagic and turbiditic sediments (5.1–7.4 ϕ; crudely laminated, bioturbated, homogeneous sand, and disintegrated sand and sandy mud facies) bearing pore-filling gas hydrates, or disseminated gas hydrates either formed in pores or small fractures of fine-grained sediments. Core-log measurements are highly fluctuating and sensitive but mostly lower (e.g., density and resistivity) than LWD records.</P> <P><B>Highlights</B></P> <P> <UL> <LI> UBGH2 (the Ulleung Basin Gas Hydrate Expedition 2) was performed. </LI> <LI> Digital images and X-rays of gas hydrate bearing-sediments were examined. </LI> <LI> Core image data and LWD log data were compared and studied. </LI> <LI> We suggest the relationships between gas hydrate occurrences and lithological conditions and physical properties. </LI> </UL> </P>

( Ayse Senay Sasihuseyinoglu ),( Derya Ufuk Altıntas ),( Sureyya Soyupak ),( Dilek Dogruel ),( Mustafa Yılmaz ),( Mahir Serbes ),( Gulsah Duyuler ) 대한내과학회 2019 The Korean Journal of Internal Medicine Vol.34 No.2

Background/Aims: Morphological changes due to lung disease in patients with cystic fibrosis (CF) were evaluated using high resolution computed tomography (HRCT), and the HRCT scores obtained using the Bhalla scoring system were correlated with those obtained using clinical and laboratory indicators. Methods: Medical records of 28 children with CF who underwent chest CT in Department of Pediatric Allergy and Immunology, Cukurova University Balcali Hospital between March 2011 and January 2016 were retrospectively reviewed. Demographic data and physical examination, respiratory cultures, pulmonary function tests, and chest HRCT findings were evaluated. Patients were divided into the following two groups according to their forced expiratory volume in the first second (FEV1) values: normal FEV1 (≥ 80% of predicted values) and low FEV1 (< 80% of predicted values). Deep throat or sputum cultures were evaluated for the presence of Pseudomonas aeruginosa (PsA) and other bacteria. HRCT scans were scored using the Bhalla scoring system. Results: No significant correlation was found between the Bhalla scores and sex, age group, or height percentiles. Significant relationships were found between the Bhalla score and weight (p = 0.036) and body mass index (BMI) (p = 0.032) percentiles below the third percentile, bacterial growth in the sputum/ deep throat cultures (p = 0.009), and presence of PsA (p = 0.004). Moreover, a significant correlation was found between the Bhalla score and FEV1 (r = -0.315, p = 0.0272), forced vital capacity (FVC; r = -0.381, p = 0.0178), forced expiratory flow between 25% and 75% of FVC (r = -0.229, p = 0.0431), and BMI (r = -3.368, p = 0.050). Conclusions: Chest HRCT is an important diagnostic tool for the pulmonary evaluation of children with CF.

Background: Lung cancer is the most common cancer in males worldwide. The principal mode of treatment in the early stage of non-small cell lung cancer (NSCLC) is surgery. However, five-year survival is only about 15% for all stages. The aim is to investigate the effect of daily low dose cisplatin concurrently with radiation therapy in advanced NSCLC patients with poor performance status. Materials and Methods: Ten patients diagnosed as inoperable Stage IIIB NSCLC with comorbid disease were assessed retrospectively in Bezmialem Vakif University, Faculty of Medicine, Department of Radiation Oncology, between 2011 to 2013. ECOG performance status was between 3 and 4. Cisplatin was administered at $6mg/m^2$ daily, for 5 days a week concurrently with radiotherapy using 160-200 cGy daily fractions, 54 Gy being the lowest and 63 Gy being the highest dose. Results: Complete response at the primary tumour site was obtained in 20% patients. Grade I esophagitis was seen 70 percent of patients, and the grade II haematological toxicity rate was 20 %. Median survival time was 7 months. Conclusions: Median survival time was reasonable, despite the patients ECOG performance status of 3-4, which is similar to groups even without comorbid disorders in comparison to other published papers in the literature. Acceptable toxicity, high response rates and quality of life of patients are the other favourable features.

Benli, Ali Ramazan,Senay, Demir Yazici,Koroglu, Mustafa,Mutlu, Tansel,Erturhan, Selman,Ogun, Muhammet Nur,Sunay, Didem Korean AcupunctureMoxibustion Medicine Society 2018 Korean Journal of Acupuncture Vol.35 No.1

This case report demonstrates the beneficial effects of cupping therapy (CT) in a 35-year-old man who is diagnosed with a fracture of the radial shaft due to a motorcycle accident. One year after the treatment started, pseudoarthrosis developed in the radius and an autogenous iliac bone graft was performed. However, extension dysfunction in the wrist became evident. After another 6 months of physical therapy and rehabilitation, no improvements were observed. Therefore, CT and adjunctive electrostimulation were performed, after 30 days of treatment, marked recovery of muscle function and full wrist extension were observed, as determined by electromyography and a grade 5/5 on the Medical Research Council power of wrist extension scale. The results in this case study suggest that CT in conjunction with adjunctive electrostimulation, may accelerate functional recovery from postoperative radial palsy, and provide a useful alternative treatment in this situation.

Nilay Kandemir Besek,Senay Asik Nacaroglu,Mehmet Onur Er,Ahmet Kirgiz,Fevziye Ondes Yilmaz,Burç,in Kepez Yildiz,Mevlut Celal Ocal 대한안과학회 2021 Korean Journal of Ophthalmology Vol.35 No.5

Purpose: We investigated the effect of the time of secondary intraocular lens (IOL) implantation on final visual acuity and other causes affecting visual prognosis in cases left aphakic after open globe injury. Methods: The study included 62 eyes of 62 patients left aphakic after the repair of open globe injury between 2012 and 2019. Demographic characteristics, trauma zone, ocular trauma score, type of injury, time of secondary IOL implantation, final best-corrected visual acuity (BCVA), and complications were recorded for each patient. Results: The mean follow-up time of 62 patients was 25.05 ± 12.59 months. The preoperative BCVA was found to be 2.40 ± 0.86 logarithm of the minimum angle of resolution (logMAR), while the postoperative final BCVA was found to be 0.53 ± 0.70 logMAR (p < 0.01). The mean interval timing of secondary sulcus foldable IOL implantation was determined to be 3.79 ± 4.04 months. No correlation was observed between secondary IOL implantation time and final BCVA (r = 0.140, p = 0.319). Furthermore, when only pediatric patients were taken, an excellent positive correlation was found between the secondary IOL implantation time and final BCVA logMAR (r = 0.895, p < 0.01). Multiple linear regression on final BCVA with age, revealed a significant model explaining 48.0% of the variability with younger age and better final BCVA with as significant coefficients (p= 0.007). Conclusions: Although time interval between primary repair and secondary IOL implantation to correct aphakia does not effect final BCVA in adult patients, earlier surgery should be considered for amblyopia management in pediatric patients.

Ismihan Goze,Ahmet Alim,Senay Akkus Cetinus,Ali Cetin,Nedim Durmus,Ahmet Turan Atas,Nilufer Vural 한국식품영양과학회 2010 Journal of medicinal food Vol.13 No.3

The radical scavenging, antimicrobial, and antispasmodic activities and the composition of Origanum acutidens (Hand.-Mazz.) Ietswaart (Order Labiatte) essential oil were evaluated in vitro. Gas chromatography/mass spectrometry analysis of the oil resulted in the identification of 20 compounds, representing 93.61% of the oil; carvacrol (65%) was the main component. The sample was also subjected to a screening for antioxidant activity by using the 1,1-diphenyl-2-picrylhydrazyl and β-carotene/linoleic acid assays. The essential oil exhibited strong antioxidant activity. Using the agar disk diffusion method, antimicrobial activities of the essential oils were determined for nine microorganisms; antimicrobial activity was shown against eight of them. O. acutidens oil exhibited spontaneous contractions in rat ileum at the 100% level at 0.1mg/mL level.

Tsunami hazard from submarine landslides: scenario-based assessment in the Ulleung Basin, East Sea (Japan Sea)

Roger Urgeles,박장준,이상훈,Senay Horozal,Deniz Cukur,김성필,김길영,정승원,엄인권 한국지질과학협의회 2019 Geosciences Journal Vol.23 No.3

In this study we use a scenario-based approach to highlight potential tsunami hazard from actual Late Pleistocene submarine landslides in the Ulleung Basin: two submarine landslides on the western slope of the Ulleung Basin, north and south of the Hupo Bank (2.53 and 1.12 km3 respectively) and a landslide (15.1 km3) on the continental slope south of the Ulleung Basin. The simulations attempt to highlight the consequences, should one of these events occur at Present. Results of the simulations indicate potential local hazard zones with very local waves < 2 m high in the Korean coast of the East Sea that could result from midsized landslides, not exceeding 3 km3 on the western slope of the basin. Time available for early warning since onset of these events is between 15–30 minutes. On the other hand, the continental margin south of the Ulleung Basin is an area where landslide tsunamis with significant hazard potential could originate. New landslides of similar size to those of the Late Pleistocene could produce tsunami waves > 3 m in the stretch of coastline from Ulsan in the south to Uljin in the north. The timing available for early warning from landslide tsunamis originating in this area is 15–30 minutes along the affected section of the shoreline. We also suggest a Probabilistic Tsunami Hazard Assessment (PTHA) for comprehensive assessment of the Korean coast of the East Sea. PTHA accounts for uncertainties in location, release mechanisms, evolution, and return periods of submarine landslides as well as epistemic uncertainty. However, to constrain these uncertainties detailed information on source areas, recurrence period and dynamics of submarine landslides is necessary and calls for additional data collection and further studies.
