Authors: Catalán-Eslava María , González-Víllora Sixto , Pastor-Vicedo Juan C. , Contreras-Jordán Onofre R. 
Published: March 2018

AbstractThe objective of this study was to analyse the differences in tactical principles, decision-making and execution of the return shot and drop shot of squash players at different levels of proficiency. The sample was composed of 80 players, divided into four levels of expertise (first national category, second national category, autonomous regional level and provincial level). The Squash Performance Evaluation Tool was used for recording the level of decision-making and execution. The results revealed that reading of the context of the game improved as the level of the player’s expertise of both the return shot and the drop shot increased. The correlation between correct decision-making and better quality execution for both the return shot and the drop shot in squash also improved with the player’s level of expertise. According to these results, improvements in situational tactical principles and the application of tactical principles, correct decision-making and high-quality execution are essential to develop the athletic performance level among squash players.

Abstract
There is no clear evidence that vitamin D effectively improves physical capacity in high-level athletes. The aim of this study was to confirm that vitamin D supplementation of soccer players during eight-week high-intensity training would have a significant effect on their aerobic capacity. The subjects were divided into two groups: the experimental one that was supplemented with vitamin D (SG, n = 20), and the placebo group (PG, n = 16), not supplemented with vitamin D. All the players were subjected to the same soccer training described as High-Intensity Interval Training (HIIT). The data of the vitamin D level, PWC170, lactate threshold (LT) were collected just before and after the intervention. A significant increase in vitamin D concentration (119%) was observed in the supplemented group, while the non-supplemented group showed a decrease of 8.4%. The studied subjects improved VO2max results by 20% in the SG, and by 13% in the PG. The improvement in velocity at the LT was similar in both groups. Results of this study show that vitamin D can have a positive, though moderate, effect on aerobic performance in players subjected to high-intensity training in the form of small-sided games for 8 weeks.

Authors: Chi Nguyen Thi Minh , Sa Dao Thi Ly 
Published: March 2018

Recently, the export turnover in the North Central Highlands has not reached the expected results. This means that export activities will face many difficulties and challenges. The main reasons are the unfavorable situation of coffee export, rubber prices remain low. Meanwhile, most of small and medium enterprises (SMEs) are not capable of exporting directly, mainly through export, so the export value is not calculated for the province. Strategic development, trade promotion, forecasting and analysis of market volatility have not been effective. This paper aims to analyze the current situation of agricultural export assistance for SMEs in the region. As results, that will be the basis to improve the quality of assistance aiming to promote growth of the agricultural sector as well as revenue for the region.

One of the important factors for setting up a successful startup is the financial capability of the owners. Therefore, financial inclusion has a strong correlation with startup establishment. This article tested the effects of several factors in financial index (findex) developed by World Bank on startup establishment in some OECD countries. The result showed that borrowing from friends and relatives along with from credit institutions and opening a debit account at banks have significant impacts on startup establishment in these countries. Finally, the article presented several recommendations for policy makers to stimulate the startup growth in Vietnam in the next time.

The World and Vietnamese Economy in 2017, Prospects for 2018 and Some Policy Implications for Vietnam
Authors: Nhung Nguyen Cam , Huong Vu Thanh , Phuong Nguyen Thi Minh 
Published: March 2018

This paper assesses the comprehensive macroeconomic picture of the world and Vietnam in 2017 and forecasts the outlook for 2018, and then making some policy implications for Vietnam. The world economy in 2017 is considered to be the most prosperous since 2011, thanks to the steady growth of key economies, bounced global trade, and favorable global financial conditions. However, as slow and uncertain global investment growth as well as many unpredictable factors in US government policy and Brexit, and political risks from tensions of the Korean Peninsula, 2018 will continue to witness unpredictable developments in the global economy. Faced with that situation, together with internal difficulties in the country, Vietnam should have flexible solutions, high determination and act in a drastic way in order to achieve the objectives on the economic growth and inflation as outlined. In addition, Vietnam should continue to promote the trade facilitation activities, the improvement of the business investment environment, take advantage of new opportunities to attract foreign investment capital for infrastructure construction, keep on innovating, and enhance the competitiveness to bring our economy to the path of rapid and sustainable development.

Safety and Efficacy of Angio-Seal Closure in Antegrade Superficial Femoral Artery Access
Authors: Akard William , Cicuto Kenneth , Kim Paul , Mittleider Derek 
Published: March 2018

Objective:
Arterial access for endovascular revascularization in patients with debilitating peripheral arterial disease is commonly achieved through retrograde common femoral artery (CFA) approach. However, retrograde access presents multiple technical challenges, including long distance from the access site to the target lesion, and mechanical disadvantage of working over the aortic bifurcation and often tortuous iliac vessels. Antegrade CFA access avoids these challenges but has been fraught with its own difficulties, particularly in obese patients. Antegrade superficial femoral artery (SFA) access provides the same mechanical advantages while avoiding the difficulties of antegrade CFA access, but a vascular closure device is required due to distance from the femoral head. This single-center study evaluates the safety and efficacy of the Angio-Seal device (St. Jude Medical, St. Paul, MN) in SFA punctures.

Materials and Methods:
From May 2011 to January 2015, 140 antegrade SFA punctures were performed on 110 limbs in 88 patients for endovascular revascularization, all with ultrasound guidance. Complications and patient data including age, sex, body mass index, Fontaine stage, sheath size, and intraoperative heparin doses were analyzed.

Results:
In 140 antegrade SFA punctures, there were 11 access-related complications (7.9%). The majority were hematomas or pseudoaneurysms requiring nominal or no therapy. There were 3 major complications: Two delayed access stenoses ultimately resulted in toe amputations and one hemorrhage required extended hospitalization and transfusion. Patient data analysis showed a statistically significantly increased complication rate in females (20.7%) versus males (4.5%) (p = 0.0105).

Conclusions:
Antegrade SFA access with Angio-Seal closure is safe and effective. An increased complication rate in females warrants cautious post-procedural follow-up.

Tepung kerang memiliki kandungan protein 2-3%, dan kalsium 30-40%, dengan besarnya persentasi kalsium yang dihasilkan dari tepung kerang tersebut maka diharapkan kebutuhan mineral yang dibutuhkan oleh ikan terpenuhi dan limbah yang dihasilkan pun dapat di kurangi. Penelitian ini bersifat eksperimental laboratoris menggunakan rangcangan percobaan Rancangan Acak lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. Perlakuan yang diterapkan yaitu perbedaan konsentrasi penambahan tepung cangkang kerang darah 0% (P0) sebagai kontrol, 5% (P1), dan 10% (P2), 15% (P3). Hasil penelitian menunjukkan tidak adanya perbedaan nyata pemberian tepung cangkang kerang darah pada pakan benih ikan lele dimana tingkat kelangsungan hidup yang tertinggi terdapat pada P2 (10%) sebesar 58%, pertambahan berat juga terdapat pada P2 sebesar 1,55 gr dan pertambahan panjang sebesar 1,82cm. Adanya pengaruh yang nyata terhadap pemberian pakan terdapat pada perlakuan P3 (15%) sebesar 101.88 % dimana Fhit (4.88) >Ftab (5%) sebesar 3.86 dan (1%) sebesar 6.99. Suhu dari awal hingga akhir penelitian berkisar antara 28-310C, dan untuk pH memiliki nilai kisaran antara 6,38 sampai 3,91.
