ABSTRACT

Purpose
To determine whether postpartum women (vaginal and cesarean delivery) have deficits in trunk flexor strength, fatigability and steadiness, compared with nulligravid women, up to 26 wk postpartum. We hypothesized that postpartum women would be weaker, more fatigable, and have greater torque fluctuations than controls, with cesarean delivery showing greater deficits than vaginal delivery.

Methods
Twenty-two control women (nulligravid) and 29 postpartum women (20–40 yr, 19 who delivered via vaginal birth, 13 via Caesarian section) participated. Postpartum women were tested 8 to 10 wk and 24 to 26 wk postpartum. Control women were tested 16 to 18 wk apart. Maximal voluntary isometric contractions (MVC) were performed at multiple trunk positions with the trunk flexor muscles. To determine trunk flexor fatigability, subjects performed intermittent isometric contractions at 50% MVC (6-s contraction, 4-s rest) in upright sitting until task failure. An MVC was performed during the fatiguing task (one per minute) and at 10 and 20 min of recovery.

Results
At 8 and 26 wk, postpartum women (groups pooled) were weaker at all trunk angles (38% and 44% respectively, P < 0.05) than controls despite no differences in handgrip strength. Postpartum women were more fatigable (71% and 52% respectively) and had greater torque fluctuations than controls (P < 0.05). At 8 wk postpartum, women who had a cesarean delivery, were 59% more fatigable (P = 0.004) than the vaginal delivery group, with no difference between delivery types at 26 wk postpartum.

Conclusions
Musculoskeletal recovery, including trunk flexor muscle strength and fatigability, is incomplete at 26 wk postpartum. These findings provide a rationale for future studies to address outcomes of rehabilitation programs specifically targeted at improving strength and fatigability of the trunk flexor muscles after pregnancy and childbirth.
High-Frequency Neuromuscular Electrical Stimulation Increases Anabolic Signaling

Published: March 2018

ABSTRACT

Purpose
Neuromuscular electrical stimulation (NMES) is commonly used in rehabilitation settings to increase muscle mass and strength. However, the effects of NMES on muscle growth are not clear and no human studies have compared anabolic signaling between low-frequency (LF) and high-frequency (HF) NMES. The purpose of this study was to determine the skeletal muscle anabolic signaling response to an acute bout of LF- and HF-NMES.

Methods
Eleven young healthy volunteers (6 men, 5 women) received an acute bout of LF-NMES (20 Hz) and HF-NMES (60 Hz). Muscle biopsies were obtained from the vastus lateralis muscle before the first NMES treatment and 30 min after each NMES treatment. Phosphorylation of the following key anabolic signaling proteins was measured by Western blot, and proteins are expressed as a ratio of phosphorylated to total: mammalian target of rapamycin, p70-S6 kinase 1, and eukaryotic initiation factor 4E binding protein 1.

Results
Compared with pre-NMES, phosphorylation of mammalian target of rapamycin was upregulated 40.2% for LF-NMES (P = 0.018) and 68.4% for HF-NMES (P < 0.0001), and HF-NMES was 29.3% greater than LF-NMES (P = 0.026). Phosphorylation of p70-S6 kinase 1 after HF-NMES was 96.6% higher than pre-NMES (P = 0.001) and was not different between pre-NMES and LF-NMES (although it was 50.4% higher after LF-NMES) or LF- and HF-NMES (P > 0.05). There were no differences between treatment conditions for eukaryotic initiation factor 4E binding protein 1 phosphorylation (P > 0.05).

Conclusions
An acute bout of LF- and HF-NMES upregulated anabolic signaling with HF-NMES producing a greater anabolic response compared with LF-NMES, suggesting that HF stimulation may provide a stronger stimulus for processes that initiate muscle hypertrophy. In addition, the stimulation frequency parameter should be considered by clinicians in the design of optimal NMES treatment protocols.

ABSTRACT

Purpose
This study aimed to examine the effects of two exercise regimes on physiological and postprandial lipemic responses.

Methods
Thirty-six active men (peak oxygen uptake [V˙O2peak], 46.5 ± 6.4 mL·kg−1·min−1) were randomly assigned to a high-intensity interval exercise (HIIE), involving 10 × 60 s cycling at 85% V˙O2peak interspersed with 120 s recovery; a moderate-intensity continuous exercise (MICE), involving 50 min continuous exercise at 65% V˙O2peak; and a nonexercise control (Con). In the next morning after evening exercising, fasting blood samples were obtained. Additional blood samples were obtained 1–4 h after eating a given high-fat meal that based on participants’ body mass. Carbohydrate and fat oxidation rates were measured before and after the meal.

Results
After exercise, glucose and insulin concentrations decreased by 33% and 70% in MICE compared with those in HIIE (P = 0.00–0.03). During the 1- to 2-h postprandial periods, the fat oxidation rate increased by 24%–37% in HIIE that that in MICE and Con (P = 0.01–0.03); however, the carbohydrate oxidation rate was not significantly different among the conditions (P = 0.28). During the postprandial period, insulin (P = 0.02–0.04) and triglyceride (P = 0.02–0.03) concentrations were lower in HIIE than those in MICE and Con. No difference was observed in free fatty acid or the total areas under the curve of triglyceride and free fatty acid among the conditions (P = 0.24–0.98).

Conclusion
Acute MICE improved glucose and insulin metabolism immediately after exercise. However, HIIE performed in the evening exerts more favorable effects than MICE for decreasing postprandial insulin and triglyceride levels and increasing fat oxidation in the next morning.
Television and the development of the data economy: Data analysis, power and the public interest
Authors: Doyle Gillian 
Published: March 2018

Abstract
Data analysis is steadily becoming more central to management decision-making in media organizations across the globe. The reliance of subscription video on demand (SVoD) services, such as Netflix, on data analytics to underpin decisions about new content investment is well-established. However, what are the key opportunities and challenges facing the rest of the television industry? This article examines how data analysis is facilitating improved methods of personalization and more effective intelligence about the relative appeal of content for differing audience segments. But growing reliance on big data also raises a number of critical public interest questions. This article highlights how data is now a key source of competitive advantage in the television industry and a resource that can be monopolized. It argues that media policy-making needs to pay more attention to the emergence and implications of asymmetries of power in relation to ownership and use of data in managerial decision-making.

Abstract
The term ‘binge watching’ is common in popular media and is one of several new ways of TV viewing that capitalizes on the wide availability of digital video and streaming services. However, the term lacks clear conceptualization, and the underlying motivations associated with it remain under-explored. Results from eleven focus groups of university students in the United States suggest binge watching is characterized as viewing suspenseful dramatic, narrative content for a considerable amount of time: often more than three or four hours. Analyses revealed four emergent motivations that contribute to individuals binge watching: (1) anticipation of what was coming next – facilitated by both content and technology features, (2) management of moods and excitement/ arousal, (3) procrastination and escapism, (4) social goals – related to both co-viewing, discussing content with others and identification with characters. Implications and future directions for research are discussed.
Rate of adoption determinants of innovations: A case study of digital terrestrial television
Authors: Vejlgaard Henrik 
Published: March 2018

Abstract
The rate of adoption of digital terrestrial television in Denmark was 100 per cent. In this article, an interdisciplinary approach is utilized to investigate this successful rate of adoption. Diffusion of innovation theory as well as services marketing theory and recent research on adoption of technology are integrated into the theoretical approach. The data gathering is twofold: a survey on the perceived attributes of the innovation was carried out and document data were gathered from government sources. This study shows that a 100 per cent rate of adoption can be achieved with (1) negative perception of the attributes of the innovation; (2) an authority innovation-decision; (3) use of mass communication and interpersonal communication channels; (4) communication in social networks that are not interconnected; and (5) active change agents on a comprehensive and large scale. The influence of the variables is discussed.

Abstract: Introduction: Physicians are found to have a great and increasing amount of patients suffering of vertigo in their everyday practice. For the treatment of the balance disorders, a vestibular training was introduced which played an influential role based on our study. Aim: Our aim was to create an easy and comprehensible training program which can be performed even with a family member. Methods: Our clinical treatment consists of intravenous vasoactive medicine administration, combined with vestibular training. For the investigation of the improvement we used the Jacobson and Newman questionnaire, and ultrasound-computer-craniocorpography. The statistical evaluation was based on ANOVA, Kruskal–Wallis test and Dunn’s post method (p<0.05). Results: After the combined clinical treatment, the patients’ average training results showed improvement. Following the eight-day training, the patients scored higher results from day to day due to the improvement of their abilities while doing the different tasks. Moreover, the questionnaire results also showed the improvement of their status. Conclusions: By improving the brain stem circulation, combined with an assisting training program, there is a significant decrease in the complaints and an overall improvement in the quality of life, even though the imbalance cannot be cured.

Abstract: The significantly increased incidence of stroke and systemic embolisation caused by atrial fibrillation can be prevented by adequately adjusted anticoagulant therapy. Vitamin K antagonists effectively decrease the risk of thromboembolic events but this effect is influenced by many factors. The development of the new direct oral anticoagulant drugs (DOAC) in the last few years provided new opportunities for us to choose the suitable anticoagulant therapy. According to the results of the ENGAGE AF–TIMI 48 and ENSURE-AF multicenter, randomized trials, edoxaban, the recently introduced DOAC is equally effective as the traditional coumarin therapy, nevertheless, it ensures more tolerable anticoagulation for patients suffering from non-valvular atrial fibrillation.

Penggunaan kompresor tradisional / tambal ban sangat berbahaya untuk pekerjaan bawah air, karena tidak terdapat filter penyaringan udara serta penggunaan oli sintetis yang berasal dari minyak bumi sebagai pelumas. Kasus yang terjadi pada penyelam kompresor tradisional adalah udara yang masuk ketabung tekanan tinggi tidak terfilter dengan baik dan asap dari mesin penggerak kompresor masuk bercampur kedalam tabung yang akan dihirup oleh penyelam. Udara permukaan terkontaminasi CO2 dengan konsentrasi 5-6 % maka dapat mengakibatkan sesak napas, napas cepat, dan pusing. Pada kadar 10 %, tekanan darah akan turun dan menyebabkan kehilangan kesadaran. Pada kadar CO2 yang lebih tinggi yaitu 12- 14% penyelam akan mengalami depresi pernapasan dan saraf pusat yang mengakibatkan kematian (Bailey et al., 2005).

Indonesia di masa mendatang akan menghadapi krisis energi konvensional dalam hal kaitannya dengan peningkatan kapasitas kebutuhan, pasokan yang terus menurun, harga tinggi dan permasalahan lingkungan yang ditimbulkan. Potensi energi laut Indonesia yang belum banyak dimanfaatkan dapat menjadi salah satu sumber energi alternatif yang bersih, dapat diandalkan dan terbarukan. Untuk dapat memanen energi yang dihasilkan dari arus laut tersebut, Pusat Pengkajian dan Perekayasaan Teknologi Kelautan dan Perikanan (P3TKP)-BalitbangKP merancang dan mengembangkan twin series vertical turbin tipe drag release yang diharapkan dapat berputar pada putaran rendah. Studi lanjutan tentang bentuk blade-nozzle-guide vane serta kombinasi diantara ketiganya menjadi fokus utama agar dapat menghasilkan target output sebesar 10 kW.
DAMPAK GELOMBANG EKUATORIAL ROSSBY TERHADAP PRODUKTIVITAS PERAIRAN, BARAT PASIFIK WARM POOL
Authors: Waas Harold J. D. , Siregar Vincentius P. , Jaya Indra , Gaol Jonson Lumban 
Published: March 2018

Gelombang ekuatorial Rossby selama ENSO berperan penting di perairan oligotropik Barat Pasifik Warm Pool (BPWP) melalui efek rototiller gelombang Rossby. Dampak utamanya adalah blooming fitoplankton pada puncak gelombang dan pengangkatan kedalaman klorofil-a maksimum mendekati (di atas) dasar lapisan pencampuran. Kontribusi gelombang Rossby dalam meningkatkan produktivitas primer permukaan perairan berdasarkan hasil perhitungan data klimatologi dan data set bulanan ocean color berkisar antara 4 – 38% karena konsentrasi fitoplankton yang tinggi berada di bawah kedalaman lapisan pencampuran dan zona kedalaman optikal SeaWIFS. Walaupun kontribusi gelombang Rossby rendah tetapi secara signifikan berkontribusi terhadap tingginya hasil tangkapan tuna selama akhir episode ENSO (Januari – Maret). Aspek lain gangguan gelombang adalah peningkatan kelimpahan group fitoplankton Cyanobacteria dan Coccolitophores (komponen dari microbial loop) dasar dari rantai makan tuna dan mendominasi sebagian besar produksi primer pada puncak gelombang dan kedalaman klorofil-a maksimum.

Published: March 2018

Mempertahankan mutu produk perikanan adalah hal yang urgent harus dilakukan terkait adanya beberapa kasus penolakan produk ekspor perikanan Indonesia oleh beberapa negara tujuan ekspor seperti Jepang, Uni Eropa dan USA. Kementerian Kelautan dan Perikanan (KKP) menegaskan bahwa keamanan pangan harus dijamin sepanjang rantai produksi berlangsung untuk tetap terus meningkatkan kualitas produk perikanan. Oleh karena itu, KKP perlu mengoptimalkan fungsi pelabuhan perikanan yang merupakan ujung tombak dan prime mover dalam kegiatan pengelolaan dan pemanfaatan sumberdaya ikan dan lingkungannya mulai dari praproduksi, produksi, pengolahan, dan pemasaran. Salah satu konsep yang akan diterapkan oleh KKP adalah fishing ecoport yang mengadop konsep negara-negara Uni Eropa dalam pengelolaan lingkungan pelabuhan untuk peningkatan produksi perikanan yang bermutu dengan berpegang pada prinsip biosecurity dan tracebility produk yang dihasilkan. Pelabuhan perikanan yang menjadi kawasan percontohan penerapan konsep fishing ecoport ini adalah Pelabuhan Perikanan Samudera (PPS) Bitung.
