Introduction: Overweight currently has become a major global burden. Salmon is one of the major sources for fish oil to treat inflammatory related cardiovascular diseases. Yellow-stripe scad (YSS) on the other hand, is a local Malaysian fish which can be a good substitute for salmon; however, the therapeutic effects of YSS is still unclear. Objective: Therefore, this study compared the nutritional values EPA+DHA of YSS and salmon on body mass index (BMI), leptin and activation markers for both platelet and endothelial cell. Methods: Healthy overweight Malaysian adults (n=45), aged 21-55 years old, were recruited for 6-months cross-over trial study. They were randomised equally to receive eight weeks of either steamed whole YSS fish or salmon fillet, for three days per week, obtaining approximately 7000 mg EPA+DHA weekly. The diets were switched after an eight-week washout period. Baseline dietary fish intakes were similar in the two groups. Results: Significant differences observed in serum leptin for YSS-baseline group I and salmon-baseline group II (p<0.05). Significant changes were observed in serum P-selectin, sCD40L and IL-1β in YSS-baseline group I (p<0.05) but not in VCAM-1 (p>0.05). Significant decreased were also observed in serum vWF and VCAM-I in salmon/baseline group II (p<0.05), but not in P-selectin, sCD40L and IL-1β (p>0.05). However, there was no significant differences between YSS and salmon (P>0.05) on time and treatment in all variable after 16 week, but there was a significant effect of treatment on sCD40L from YSS and vWF from salmon (p<0.05) Conclusion: Both YSS and salmon could harmonized EPA+DHA into leptin, platelet and endothelial phospholipid membrane to decreased platelet and endothelial cell activation markers which may contribute to the cardioprotective effect of EPA +DHA. Thus, the health benefits of YSS fish “ikan selar” and salmon on leptin and prothrombotic parameter on healthy overweight adults may be similar.

<p><em>One of the ideal geometric characteristics of a component is a smooth or rough surface. In practice, it is not possible to obtain a component with a smooth/rough surface. This is due to several factors, such as the human factor (operator) and the factors of the machines used to make it. However, with technological advancements, the growing apparatus capable of forming surface components with a high degree of fineness/roughness, according to the standard measures applicable in metrology, is advanced by geometric measurement experts through research experience. </em><em>Fineness level/roughness of a surface is very important role in the planning of a machine component, especially concerning the problem of lubrication friction, wear and tear, resistance to fatigue and so on. Therefore, in the planning and manufacture must be considered first about which machine equipment should be used to make it and how much the cost must be incurred. In order for the process of manufacture, there is no significant deviation, then the characteristics of this surface should be understood by the planner even more by the operator. Communication of surface characteristics is usually done in engineering drawings. But to explain perfectly about the characteristics of a surface seems difficult. </em><em>The research method is started by preparing instrument that is Milling Machine which is used to make surface roughness and Surface Roughness Tester is done 3 times test with variable speed of food which is different equal to 7,3; 13; 24.5 mm/put. With a speed of 102 rpm Rpm, and a depth of 0.4. Next, determine the material roughness level with Surface Roughness Tester. After all, done will get the data test results, followed by analysis and discussion so that will get final conclusion. </em><em>From the research results obtained the following results: there is a difference in the level of roughness in each material with different feeding speed. The feed rate of 7.3 mm / put yielded 0.64 μ, 13 mm / put roughness generated 1.32 μ, 24.5 mm / put yielded 3.77 μ. The process of measuring the roughness of the material with the speed of feeding is slower, the smoother the surface roughness, the faster the speed of the feeding the more rough. The range of syrup result is also influenced by the speed of the food. The faster the movement of the range range the wider the surface roughness is the opposite.</em></p>

Türkiye’de Kiraz Üretiminin Yapısal Analizi
Authors: ÇELİK Yusuf , SARIALTIN Hatice Kübra 
Published: October 2019

Bu çalışmada, Dünya’da ve Türkiye’de kiraz üretiminin
mevcut durumu incelenmiş ve Türkiye’de kiraz sektörünün SWOT analizi
yapılmıştır. Araştırmanın temel materyalini ilgili istatistikler ve yapılmış
olan bilimsel çalışmalar oluşturmuştur. 2017 yılı FAO verilerine göre Dünya’da
yaklaşık 416.445 hektar alanda kiraz üretimi yapılmakta ve 85.401 hektar alan
ve 627.132 tonluk üretim ile Türkiye dünyada kiraz üretiminde ilk sırada yer
almaktadır. Üretim bakımından ilk sırada olmasına rağmen pazarlama stratejilerinin
etkin ve yeterli olmamasından dolayı kiraz ihracatında Türkiye, Şili ve ABD’den
sonra üçüncü sırada yer almaktadır. Türkiye’nin ağırlıklı olarak kiraz ihracatı
yaptığı ülkeler, Avrupa Birliği ülkeleri (Başta Almanya, Bulgaristan ve
Hollanda olmak üzere), Rusya ve Irak’tır. Dünya kiraz ithalatında ilk sırada
%21 oranıyla Çin, ikinci sırada ise %19’luk oranı ile Rusya gelmektedir.
Türkiye’de ağaç başına kiraz verimi 2017 yılında 29 kg olarak gerçekleşmiştir.
Türkiye’de 2018 yılı verilerine göre kiraz üretimi bakımından, Konya ili ilk
sırada yer almıştır. Konya ilinde 70.987 da alanda, 68.376 ton kiraz üretimi
yapılmış olup, bu miktar toplam kiraz üretiminin %10,87’sini oluşturmaktadır.
Üretim bakımından ikinci sırada İzmir ili gelmektedir. Türkiye’de kiraz
sektörünün yapılan SWOT analizinde, Türkiye’nin sahip olduğu ekolojik çeşitlilik
ve uygunluk avantaj oluştururken, işletmelerin yapısal sorunları ve üretici
örgütlenmesinin yetersiz olması dezavantaj oluşturmaktadır. Diğer taraftan
Türkiye’nin Avrupa Birliği ve Rusya gibi ithalatı yüksek ülkelere yakın ve iş birliği
içinde olması fırsat oluştururken, yaşanan iklim değişikliğine bağlı üretim ve
fiyat istikrarsızlığı önemli riskler oluşturmaktadır. İhracat olanaklarını artırabilmek için üretici örgütlenmesi ve üretici
örgütlerinin etkinliğini artırmak, kiraz üretim tekniklerinin bilimsel esaslara
göre yürütülmesi, uluslararası piyasalarda tat ve aroma bakımından tercih
edilen kiraz çeşitlerinin yaygınlaştırılması gerekmektedir.&nbsp;
