2020 Yılında Bölgesel Kalkınmaya Birçok Alt Sektörle Birlikte Etki Eden Tersane Havuzlarındaki Bakım Onarım Süreçlerinin İstatistiksel Olarak İncelenmesi Ve Değerlendirilmesi
(Yalova Araştırmaları Kongresi - YAK2021, 2021-10-23) Kalkan, İsmail; Baytemür, Atilla; Erkurtulmuş, Selahattin Alp; Eren, Şükrü
Yalova sanayisinin lokomotif sektörlerinden birisi olan ve ülkemizin ihracat açığının kapanmasında önemli katkılar sağlayan bölgemizdeki tersanelerde gerçekleştirilen birçok genel ve spesifik gemi inşaatı projelerine ilaveten, faaliyet halindeki gemilerin periyodik bakım veya tamir bakım işlemlerinin gerçekleştirilebilmesi için yüzer veya kuru havuz faaliyetleri gösteren işletmelerin katkısı yadsınamayacak kadar önemlidir. Yalova ili Altınova-Hersek bölgesindeki tersaneler, spesifik gemi inşaatı projelerinde yakaladığı başarıyı yine aynı şekilde, havuzlarda gösterdiği bakım onarım faaliyetlerinde de sağlamıştır. Genel kargo gemisi, yük gemisi, dökme yük gemisi gibi gemilere ilaveten; kimyasal tankeri, ham petrol tankeri, LPG tankeri, Ro-Ro gemisi, balıkçı gemisi, dredger gemisi vb. gemilerin de havuzlarda bakım onarım faaliyetlerini, dünya standartlarında gerçekleştirebilecek mühendisliksel ve operasyonel bilgi, tecrübe ve altyapı yeterliliğine ulaşmıştır. Bu çalışmamızda, bölgede gerek istihdam ve üretim açısından, gerekse de havuz adedi ve çeşitliliği açısından öncü konumda bulunan örnek bir tersane seçilerek gemi türüne göre proje çeşitleri, ülkelere göre müşteri dağılımı, genel istatistikler, taşeronlar ve insan gücü tahsis istatistikleri ve gider tahsis istatistikleri vb. bulgular ortaya konularak sonuçların değerlendirilip imalat, hizmet ve mühendislik alanında faaliyet gösteren firmalara farkındalık sağlayarak ileri dönük yapılacak çeşitli akademik çalışmalara kaynak sağlanması amaçlanmıştır.

(Ege Üniversitesi Su Ürünleri Fakültesi Dergisi, 2003) Tekinay, Ahmet Adem; Alpaslan, Mustafa; Özen, Özcan; Akyüz, Pınar; Kahyaoğlu, Gülçin Ebru; Güroy, Derya
A total of 86 different fish species were recorded in Istanbul Fish Market between 1998 and 2001. During these years, the highest productions were recorded for european anchovy (Engraulis encrasicholus Linnaeus, 1758), horse mackerel (Trachurus trachurus Linnaeus, 1758), bonito (Sarda sarda Bloch, 1793), bluefish (Pomatomus saltatrix Linnaeus, 1766) and whiting (Merlangius merlangus euxinus Nordmann, 1840). Total production amount of these 5 species was 80.1% of the production for the investigated years. Annual fish production varied between 23825 and 25228 ton from 1998 to 2000, however, the total production of 2001 was recorded as 36771 ton, an increase of 51%. November and October were observed as the highest production months during the fouryear period. In 2001, the highest increase in terms of percentage compared to the previous three years production was observed in bluefish (497%).
A RESEARCH TO DETERMINE THE ETHICAL CLIMATE PERCEPTION OF NURSES WHO WORK IN PRIVATE HOSPITALS
(Journal of International Health Sciences and Management, 2021-10) AVÇİN, Emel; CAN, Şeyda; ERKOÇ, Beyza; YEŞİL, Fatma; ERDOĞAN, Gürkan
Objective: It’s imperative that organizations that want to exist in the business world where competition is intense and that want to ensure should create a positive ethical climate perception. The aim of this study was to determine the level of perceptions of the ethical climate of nurses who work in a private hospital and to determine whether ethical climate perceptions differ according to demographic characteristics. Methods: The study was conducted between July-September 2018 on 154 nurses working at two private hospitals(in Istanbul and Yalova). Research data were collected from nurses working in these hospitals. This is a descriptive cross-sectional study. Results: According to findings, it was determined that the ethical climate perception of the participants was generally positive. In dimensions, ethical climate perception was found most positive in patient dimension, while most negative in physicians dimension. At findings, the perception of ethical climate according to the gender of the participants differed statistically in the managers dimension and perception of ethical climate according to working time in hospital differed in patients dimension(p<0.05). Perception of ethical climate didn’t differed significantly with age, educational and marital status of participants (p>0.05). Conclusions: It was determined that the hospital ethical climate perceptions of the nurses in the study were highly positive, and this perception was influenced by gender and the year of work. The sub-dimension, where the ethical climate perception was the most negative, was the physician dimension. It’s thought that the results obtained can be a guide in supporting positive ethical behavior.
An investigation on some population parametres of European pilchard (Sardina pilchardus Walbaum 1792) in the Dardanelles
(2002) Tekinay, Ahmet Adem; Akyüz, Pınar; Güroy, Derya; Kahyaoğlu, Gülçin Ebru; Alpaslan, Mustafa
In this study, the lenght-weight relationship, condition factor (CF), gonadosomatic index (GSI) and meat yield of 363 Europen pilchard (Sardina pilchardus Walbaum,1792) sample from Dardanelles were studied between Semtember 2001 and April 2002. The lenght-weight relationship was calculated as W=0.0172L2.68; R2=0.71. Mean condition factor of males and females varied between 0.66-0.87% and 0.68-.0.86%, while mean GSI values were 0.34-4.83% and 0.47-5.95%, respectively. Percentage meat yield of males and females were varied as 64.21-75.56 and 64.20-81.50, respectively.
Artificial sex reversal of white grouper (Epinephelus aeneus) utilizing aromatase inhibitor (Fadrozole)
(Aquaculture Research, 2019-03-20) Evliyaoğlu, Ece; Eroldoğan, Orhan Tufan; Yılmaz, Hatice Asuman; Genç, Münevver Ayçe; Genç, Ercüment; Duncan, Neil; Aktaş, Mevlüt; Güroy, Derya
The white grouper is a desirable aquaculture species that adapts to captivity, grows well and commands a high market price. However, little is known about reproductive biology or control of sex reversal of this protogynous hermaphrodite. In this study, female white groupers were implanted with one dose of 17α‐methyltestosterone (10 mg/kg body weight [BW], MT) and two doses of aromatase inhibitor, fadrozole (1 and 3 mg/kg BW, FD1 and FD3) once a month for 4 months (April–July). At the start of the study, the fish had gonads full of oocytes compared to the end of the experi‐ment when the control group mature oocytes compared to the experimental groups MT, FD1 and FD3 that exhibited different stages of testicular tissue. Plasma levels of testosterone were significantly highest in the FD3 group and the highest 11 -Ketotestosterone levels were observed in the MT group. Plasma levels of oestradiol (E2) were significantly lower in the FD implanted groups, compared to initial individu‐als and control groups. The use of aromatase inhibitor, FD for sex reversal both gives further insight into the mechanisms controlling sex differentiation and provides an alternative to steroid treatment
Asylum Seeker Identity and the Labor Market: Syrian Asylum Seeker in Turkey
(Rainer Hampp Verlag, 2019-11) Alpman, Polat S.
This work focus on the term “asylum seeker.” Interestingly, although Syrian asylum seekers have sought refuge in Turkey, they have not been given the status of “refugee.” Why this has happened and its effect on the construction of identity as well as in the labor market will be discussed in this work. One of the fundamental reasons why those who come to Turkey seek refuge but cannot find it, why millions cannot take advantage of refugee status, and why they find themselves in the labor market as asylum seekers, can be found in the specific conditions in which the “immigrant identity” is constructed in Turkey.

Balık üretiminden kaynaklanan kirlilik ve çözüm yolları
(Ege Üniversitesi Su Ürünleri Fakültesi Dergisi, 2006) Tekinay, Ahmet Adem; Güroy, Derya; Çevik, Nazan
Aquaculture pollution mainly originates from the physical and chemical characteristics of feed and the applied feeding management. The production of fish feed by using the extruder technology prevents the dust and broken particles formation by enhancing the water stability of feed. Feed loss is prevented by controlling the sinking rates of feed. By using the appropriate mechanical equipment during feed production, the feed density can be adjusted according to the freshwater and marine environment. Instead of oil spraying, the use of vacuum coating for oil addition of feed prevents oil leakage into the aquatic environment. The choice of highly digestible feed ingredients with low cellulose content and the application of heat treatment (85 – 90 °C) for an appropriate period of time to feed in the preconditioner decreases fecal waste production by increasing carbohydrate digestibility. The balancing of the Nitrogen: Phosphorus and Protein: Energy ratios in the feed formulations provide the decreasing of the amount of dissolved ammonium, and phosphorus released to the environment. The pollution, due to fish feeding, may be also minimized through developing feeding tables according to the Thermal Growth Coefficient (TGC) of fish based on the characteristics of the fish farms
Bezelye protein konsantresinin granyöz (Argyrosomus regius) balıklarında büyüme performansı biyolojik parametreler vücut kompozisyonu ve amonyak boşaltımı üzerine etkileri.
(Ege Journal of Fisheries and Aquatic Sciences, 2017) Güroy, Derya; Mantoğlu, Serhan; Karadal, Onur
Using of alternative plant/animal based (except fish meal) raw materials is one of the most important application for decreasing feed cost in finfish feeds. Meagre which is demanded from many countries because of its efficient meat quality and flovur and showed rapid growth under culture conditions is a potential species. A nutrition trial with meagre, Argyrosomus regius was undertaken to evaluate the effect of replacing dietary fishmeal (FM) protein with pea protein concentrate (PPC). A diet with FM as the main protein source was used for the control diet (FM). Four experimental diets were formulated to progressively replace 15% (PPC15), 30% (PPC30), 45% (PPC45) and 60% (PPC60) of FM protein. The study was carried out in 450-L fiberglass tanks connected to a closed recirculation system. Eighteen fish per tank were randomly distributed into 15 tanks with three replicates. The diets were tested in triplicate for 12 weeks. The specific growth rate (SGR) of fish fed diet PPC15 were not significantly different compared to fish fed the FM diet (P>0.05). Meagre fed FM, PPC15 and PPC30 had significantly lower FCR compared with fish fed PPC45 and PPC60 (P<0.05). Total ammonia-nitrogen (TAN) excretion increased with elevated dietary PPC inclusion. In conclusion, using 15% of pea protein concentrate in meagre feeds has been recommended.

(Yalova Araştırmaları Kongresi - YAK2021, 2021-10-23) Baytemür, Atilla; Erkurtulmuş, Selahattin Alp; Kalkan, İsmail; Eren, Şükrü
Tersaneler, tüm su araçlarının yeni inşa, bakım onarım veya tadilat işlemlerinin yapıldığı tesisler olarak adlandırılmaktadır. Ülkemizde üretim, ihracat ve istihdam kapasitesi yönüyle ön plana çıkan en önemli tersane bölgelerimizden bir tanesi de Yalova Altınova Tersaneler Bölgesidir. Bu bölgedeki bazı tersaneler sadece yeni inşa alanında hizmet verirken, bazı tersaneler de yeni inşa faaliyetlerinin yanı sıra tersane bünyesinde bulunan kuru havuz veya yüzer havuzlarda bakım onarım faaliyetleri vermektedir. Gemilerin bünyesinde ve donatımında gerçekleştirilen tüm elektriksel, boyama, borulama, sac işçiliği ile ana makine ve yardımcı makinelerin tamiri vb. iş ve işlemler tersanelerde bakım onarım faaliyetleri kapsamında değerlendirilmektedir. Yalova Altınova bölgesindeki tersanelerin yeni inşa ve tadilat faaliyetlerinin yanı sıra ,dünya standartlarında bakım onarım faaliyetleri gerçekleştirmesi, bölgedeki birçok kobi, küçük sanayi kuruluşları, esnaflar ve bölge halkının ekonomik refah düzeyini doğrudan etkilemektedir. Bu çalışmada, bölgede istihdam ve üretim açısından önemli konumda bulunan örnek bir tersane seçilerek 2021 yılının ilk 6 ayında havuzlardaki bakım onarım faaliyetleriyle ilgili bulgular ortaya konularak elde edilen sonuçlar irdelenerek gelecek dönemlere yönelik yapılacak çalışmalara ışık tutması; böylelikle de tersanelerde çok önemli bir yeri olan havuzlardaki bakım onarım faaliyetleri üzerinde literatürde yeterince yayın olmadığı için literatüre kaynak sağlanması amaçlanmıştır.

A comparison between the records of Çanakkale Fish Market and fisheries production of Çanakkale Region from 1996 to 2001. In this study, Çanakkale Fish Market records and Çanakkale fisheries production data obtained from Ministry of Agriculture and Rural Affairs, Province Directorate of Çanakkale were investigated from 1996 to 2001. The highest market records (432.0 ton) and fisheries productions (22 050.6 ton) were observed in 2001. For the years investigated, the sum of the monthly production in the fish market were highest in October and November (183.6 and 183.5 ton, respectively). A total of 65 different marine species were recorded in Çanakkale Fish Market whereas only 25 different marine species were reported by Ministry of Agriculture and Rural Affairs, Province Directorate of Çanakkale. Although the greatest amount in the Fish Market were gilt sardine, anchovy, and bluefish, the greatest fishing production in the Çanakkale region were reported as gilt sardine, tuna and bluefish. In contrast to the fishing production of Çanakkale region, tuna entered the Fish Market only in August, 2001. Çanakkale Fish Market records and the fishing production of Çanakkale region did not differ only in the amount but also in the species composition. Based on such conflicting statistics, decisions on fisheries management would be erroneous.

(Astana Yayınları, 2021-11-13)
Covid-19 pandemic which creates panic, fear and uncertainty in every part of society is threatining life seriously. Covid-19 pandemic constitutes a reaction in society with measures that decelerating or stopping social and economic life. The react by society is existing by unwearing a mask, violating social distance rules, violating the quarantine measures. It’s undeniable that the reaction’s reasons are economical dynamics. Lockdowns for those who have to work for economic reasons, quarantine practices at home cause job losses, and therefore those who have to work tend to break these bans. However, in order to get out of the pandemic situation, a cooperation should be established between infected patients and the administration. Failure to ensure the said cooperation for economic reasons or other dynamics will result in the state authority using its penalizing authority. In this respect the crime of violating the measures related to infectious diseases is one of tools of state which uses as a last resort so as to ensure adapted to the measures. In this paper, the elements of TCK m.195 crime are examined and the applicability of the relevant crime is discussed in the case of Covid-19.
COVİD-19 DÖNEMİNDE SEYAHAT AŞERME VE SEYAHAT MOTİVASYONLARI
(ASOS JOURNAL The Journal of Academic Social Sciences, 2021-07)
Bireyleri ya da kitleleri seyahat eylemine yönelten sebepler seyahat motivasyonları olarak ele alınmaktadır. Genel olarak insanları seyahate yönlendiren motivasyonların dinlenme, eğlenme, sağlık, eğitim, inanç ya da işle ilgili sebeplerden beslendiği söylenebilmektedir. Covid-19 pandemisi ise seyahatlerin kısıtlandığı ve insanların seyahatlerden büyük oranda uzak kaldığı bir dönemi ifade etmektedir. Seyahat edilemeyen süreçte seyahate yönelik şiddetli arzunun bulunması; seyahat aşermesi olarak tanımlanabilmektedir. Hazırlanan çalışmada seyahatlerin kısıtlandığı Covid-19 döneminde bireylerin seyahat aşermesi ve seyahat motivasyonlarını belirlemek amaçlanmıştır. Bu kapsamda kolayda örneklem ile belirlenen 465 kişiye online olarak ulaşılmıştır. Yapılan analizler sonucunda katılımcıların Covid-19 döneminde seyahat aşerme düzeylerinin genel olarak ortalama altında kaldığı dikkat çekmektedir. Bu durum üzerinde Covid-19’un kendisinin, buna bağlı getirilen kısıtlamaların ve sağlık endişelerinin etkisinin var olduğu açıkça söylenebilmektedir. Seyahat eden bireylerin seyahat motivasyonlarına bakıldığında ise büyük oranda kişisel gelişim ve bilgi artırımı sebebiyle seyahat ettiklerini söylemek mümkündür. Hazırlanan çalışma sonucunda Covid-19 döneminde seyahat eden bireylerin görece genç, kendini geliştirme ve sosyalleşme arzusu duyan ve farklı deneyimler arayan kişiler olduğu söylenebilmektedir.

(İKSAD Publishing House, 2021-09) Talih Akkaya, Duygu
The Covid-19 virus, which first appeared in Wuhan, China in December 2019 and was defined as a pandemic by the World Health Organization (WHO), affected the whole world and caused the death of many people. In this process, the effect of which is still ongoing and the risk of transmission is very high, mandatory restrictions were made all over the world, most of the businesses were closed for a long time, and curfews were applied in some periods. Therefore, people stayed at home and avoided crowded environments as much as possible, and tried to meet almost all their needs, especially their basic needs, by shopping online. The already widespread internet usage and online shopping rate have increased even more with the effect of staying at home, which has led to the start of the digital struggles of businesses in the global sense. Many internet users are influenced by social media advertisements when making an online purchase decision. Therefore, the Covid-19 pandemic process has led to an increase in social media advertising investments in parallel with the increasing online spendings, and most of the businesses have started to produce effective and creative digital campaigns that are suitable for the process while focusing on advertising investments. Within the context of the study, first of all, a literature review on the Covid-19 pandemic process and social media advertising was made, then examples of successful social media advertising campaigns carried out in this process were examined and the effects of these campaigns in Turkey and in the world were evaluated.
Definition of textural deterioration in squid samples: three different tools supported by microbial, visual and physico-chemical analysis
(Ege Journal of Fisheries and Aquatic Sciences, 2021-09) Ceylan, Zafer; Çetinkaya, Turgay
The aim of the present study was to reveal the textural profile changes like hardness, cohesiveness, springiness, and adhesion supported by total mesophilic aerobic bacteria count (TMABc), pH, and some visual sensory characteristics in squid samples stored at 4 ºC. Three different Brookfield Texture Analyzer tools, named TA7, TA9, and TA18 were used to observe the textural changes more clearly. The difference of TMABc between the storage days reached from 4.32 log CFU/g to 6.32 log CFU/g. The hardness value of the squid samples, detected by TA18 and TA9 tools, increased while the hardness value obtained from TA7 was higher. The highest change in cohesiveness value in the squid samples was defined by the TA9 tool as ~63%. Once springiness values detected by TA9 were sharply decreased from 4.9 mm to 2.1 mm, those of TA7 and TA18 were slowly decreased. The most increase in adhesion value (0.08 mJ to 0.21 mJ) was obtained in the TA7 tool. Depending on the textural quality changes, the pH value was increased, and as visual and sensory, dark, or yellow spots were observed. The present study results revealed that especially the TA18 tool could be effectively used to determine the quality changes of the squid samples
