The purpose of this study was to analyze the Financial Ratio at PT Bluebird Tbk after the existence of online-based transportation facilities. The company's problem arose since the entry of online transportation facilities where there was a significant decrease in income. Ratio analysis in the opinion of Munawir An analytical method to determine the relationship of certain items in the balance sheet or income statement individually or in a combination of the two reports. The research method used is liquidity ratio, solvability ratio and profitability ratio. The results show that the relationship between liquidity and solability can be said to be "liquid and solvable", meaning that the condition of the company is declared healthy and in good condition because the company is able to pay off its obligations that are due on time. Furthermore, the relationship between solvency and profitability can be said as "solvabel and inprofit", meaning that the condition of total corporate debt tends to decrease, not accompanied by a decrease in profit from year to year. Declining profit growth does not affect the rate of return on short-term debt from the company. This means that even though profits are reduced, the company can still return the current debt fairly well. Thus, after the entry of other online-based transportation facilities there is a downward trend in indicators of profitability, while in the other two indicators tend to be in a good position. This is because the company has not been able to manage financial performance in terms of profitability efficiently.

Imotilization of fish is one way of handling techniques by using low temperature (cooling). Cooling (cold chain) is applied to transport live fish so that the weight of the load during transportation could be reduced and fish do not experience stress during transportation. This technique is more advantageous when compared with the wet transportation system by using water. After the fish fainted, fish could be re-awakened by returning the fish to the pond with the aid of sufficient aeration to facilitate fish regain consciousness. This study aims to determine the rate of stunning, the speed of awareness, and mortality of nile tilapia fish which was treated and stored at different temperatures and times. This study used a factorial completely randomized design (RAL) with 2 treatments namely, storage method (A) treatment consisting of 2 storage levels (Temperature 10-12 ° C and 14-16 ° C); and storage time (B) consisting of 4 levels (2, 4, 6 and 8 hours). The optimum time of fainting fish is at a temperature of 14-16 ° C that is 8.19 min. For re-awakening, the optimum time is 48 seconds when fish was stored for 2 hours. The best mortality rate was achieved at storage temperature ± 14-16 ° C because after 6 hours storage the mortality rate was only 20.8%, but by the maximum storage (8 hours) the mortality has reached 87.5%, Meanwhile at a storage temperature of ± 10-12 ° C, the mortality has reached 50% after 6 hours and 100% at 8 hours.Pemingsanan ikan merupakan salah satu cara teknik penanganan dengan pengunaan suhu rendah (pendinginan). Pemingsanan dengan suhu rendah diaplikasikan untuk transportasi ikan hidup dengan tujuan mengurangi berat beban selama transportasi dan supaya ikan tidak mengalami stress selama transportasi. Teknik ini lebih menguntungkan jika dibandingkan dengan transportasi sistem basah dengan menggunakan air. Setelah dipingsankan ikan kembali disadarkan dengan mengembalikan ikan ke kolam air habitatnya dengan dibantu aerasi yang cukup agar ikan kembali sadar. Penelitian ini bertujuan untuk mengetahui kecepatan pemingsanan, kecepatan penyadaran, dan mortalitas ikan nila yang dipingsankan dan disimpan pada suhu dan waktu berbeda. Penelitian ini menggunakan rancangan acak lengkap (RAL) faktorial dengan 2 perlakuan yaitu, perlakuan metode penyimpanan (A) yang terdiri atas 2 taraf penyimpanan (Suhu 10–12°C dan 14–16°C); perlakuan lama penyimpanan (B) yang terdiri atas 4 taraf (2, 4, 6 dan 8 jam). Waktu optimum kecepatan pingsan adalah pada suhu 14–16°C yaitu 8,19. Untuk penyadaran kembali, waktu optimumnya adalah 48 detik, pada ikan nili yng disimpan 2 jam. Pada penyimpanan suhu ±14-16°C didapat tingkat mortalitas terbaik karena sampai penyimpanan 6 jam tingkat mortalitasnya hanya 20,8%, namun sampai penyimpanan maksimum ( 8 jam) sudah mencapai 87,5%, sedangkan pada suhu penyimpanan ±10-12°C , setelah 6 jam mortalitasnya sudah mencapai 50% dan saat 8 jam tingkat mortalitasnya sudah mencapai 100%.

Abstract

Infective endocarditis is a serious and potentially fatal complication of central venous line (CVL) placement in patients with diseased hearts. A man of 59 was admitted because of fever and dyspnea of 5 days duration. He was a known case of ischemic cardiomyopathy with frequent admissions to a local hospital. Two months earlier, a CVL was placed in right subclavian vein for drug administration. On examination, he was febrile and hypotensive with a systolic murmur in tricuspid and mitral areas. CVL- guide wire was radiographically visible. White blood cells and C-reactive protein were elevated. Echocardiography showed big vegetation on tricuspid valve (TV), severe mitral and tricuspid regurgitation and dilated left ventricle whilst coronary angiography revealed 3-vessel disease. Antibiotic therapy was followed by an open heart surgery during which the guide wire and valve vegetation were removed, TV was repaired, mitral valve was replaced and coronary artery bypass grafting was performed. Culture of blood, valve tissue and guide wire grew Staphylococcus Epidermidis. Despite intensive medical and surgical therapy, the patient succumbed on the 4th postoperative day.

Background: Cardiac myxoma is a benign tumor that carries the risk of embolization and obstruction of the blood flow. The ideal surgical approach is still debatable. We present our experience in the surgical treatment of cardiac myxomas and its ideal surgical approach.Methods: We retrospectively analyzed the data for all patients who underwent surgical excision of cardiac myxoma at our institution over 11 years starting from January 2006 to December 2016. Descriptive statistics were used to present preoperative, operative and postoperative data and Kaplan Meier curve to plot long-term survival.Results: Twenty-one patients had surgical excision of a primary, single and sporadic cardiac myxoma. Thirteen patients (62 %) were females, and the mean age at operation was 55.2 years (range: 28 – 71 years). The location of myxomas was in the left atrium in 17 patients (81%) and right atrium in 4 patients (19 %). Dyspnea was the main presenting symptom (71.4%) followed by constitutional symptoms (28%), palpitations (23.8%), syncope (14.2%) and stroke (14.2%). A right atrial trans-septal incision was used in 76.5% of left atrial myxoma cases. Five patients had concomitant operative procedures (coronary artery bypass grafting (n=2), tricuspid valve repair (n=1), mitral valve replacement (n=1) and bullectomy (n=1)). Postoperative complications were reported in six patients (28.6%) (supraventricular arrhythmia (n=2), temporary conduction deficit (n=2), pulmonary atelectasis (n=1), and postoperative bleeding (n=1)). Early postoperative mortality occurred in one patient (4.76 %), and there were no late deaths related to myxoma.Conclusion: Surgical treatment of cardiac myxoma is safe with low morbidity and mortality. The right atrial trans-septal incision is the recommended surgical approach.

Background: Temporary postoperative pacing could enhance recovery of the cardiac function. The right ventricular pacing (RV) is commonly used, but it can cause dyssynchronous contraction of both ventricles. Biventricular pacing (BV) could improve the systolic function by synchronizing the ventricular contraction. The aim of this study is to evaluate the effectiveness of biventricular pacing in improving the hemodynamics in the early postoperative period compared to other pacing modes.

Methods: This is a clinical crossover trial including 50 patients who underwent open cardiac surgery in the period from September 2017 to September 2018. Mean age was 46.78± 12.09 years, and 50% were males. Temporary pacing leads were attached to the anterior wall of the right ventricle 1-2 cm paraseptally and the lateral wall of left ventricle 1-2 cm paraseptally. Each patient was paced for 3 minutes in the first 1-4 postoperative hours with 20 minutes washout period between different pacing modes. Study endpoints included cardiac output, ejection fraction (EF) and wall motion abnormality.

Results: Biventricular and right ventricular pacing increased postoperative cardiac output (6.31± 1.28 and 5.2±0.72 L/min; respectively), but BV pacing was superior to RV pacing (P-value <0.001). The effect of BV pacing was more evident in patients with EF < 50% (7.27± 0.895 vs. 5.26 ± 0.634 L/min; p< 0.001). The postoperative EF improved during BV pacing (53.16± 4.71%) compared to RV pacing (49.4± 4.07%; P-value <0.001). Both BV and RV pacing were associated with less paradoxical septal wall motion abnormality (P-value <0.001).

Conclusions: Temporary postoperative biventricular pacing improves hemodynamics compared to right ventricular and no pacing. Routine BV pacing is recommended especially in patients with low ejection fraction.
The assessment of language maintenance in bilingual children
Authors: Dubiel Bozena
Published: July 2019

This study investigates potential shifts in relative language dominance in early sequential bilinguals across the primary school years. The subjects are thirty-eight Polish-English speaking children. A new test, the Child HALA (Dubiel & Guilfoyle, 2017), is introduced, which measures shifts in relative language strength by comparing lexical accuracy and response time between two languages. This test has been designed specifically for use with children, and is based on the HALA psycholinguistic tool (O’Grady, Schafer et al., 2009). The aim of this study is twofold. The first goal is to evaluate shifts in the relative language strength in both languages by examining changes in lexical accuracy and response time (RT). The focus is on the impact of word frequency on lexical accuracy and access, and the link between the frequency of language use and its relative strength and maintenance in bilinguals. The second aim is to examine the CHILD HALA’s suitability, reliability and applicability in research on language acquisition and maintenance in young bilinguals. In particular, the objective is to evaluate whether the test will show a pattern of shifts in language strength comparable to the outcomes of previous research. The results show that the children’s relative language dominance shifts from the initially stronger L1 Polish to the more dominant L2 English between the age of eight and eleven. The Child HALA test discovers reliable results across age groups and languages when compared with other studies that investigated lexical accuracy and access (Kohnert, Bates & Hernandez, 1999; Jia, Kohnert, Collado & Aquino-Garcia, 2006), and therefore may be considered as a reliable method in assessing language strength and maintenance in children. The results also support the earlier finding by O’Grady et al. (2009) and Tang (2011) of the response time measure being more sensitive and precise in the assessment of language strength than lexical accuracy alone. This study contributes to the broader field of bilingual language acquisition, and the Child HALA may be considered as a reliable method in assessing language strength and maintenance in young children.
Research Methods in Foreign/Second Language Didactics
Authors: Cirocki Andrzej , Arceusz Aleksandra
Published: July 2019

This article provides an analytical overview of relevant research methods in applied linguistics significant to teaching practitioners. In the canon of language teaching literature, there are numerous volumes presenting insightful analyses of research into  English as a foreign or second language (EFL/ESL) context. This article seeks to familiarize English language practitioners with comprehensive, practical, and straightforward coverage of applied linguistics research within the three research paradigms of qualitative, quantitative, and mixed methods. The twenty-first centurychallenges societies and systems with new demands and approaches, with schools and teachers being agents of those changes, responsible for their presentation, implementation and often evaluation. Teachers must have a good understanding of  such changes and should be prepared to put new knowledge into practice. This can be achieved when a teacher becomes a researcher, engaging themselves in various activities that lead to a better understanding of the processes, to reflection upon teaching, and finally, to the implementation of new practices: becoming researchers intheir own right.
Peer Observation of Language Teaching: A Reflective Approach to Teaching
Authors: Nunan Anna
Published: July 2019

Peer observation of teaching has increasingly been considered as a means of promoting reflective practice for language teachers. An interactive model is critical to the success of the observation process as it is structured, supportive and emphasises choice, control and observation between equals. The insistence on an information flow aimed at the observed helps reaffirm the idea that observation is not an administrative exercise but a beneficial process for the teacher and learner. If peer observation can uncover some of the assumptions teachers use to shape language teaching, including the resistance to teaching as an open practice, an improvement of existing approaches to language teaching may be within reach.

This study attempted to analyze the distribution and contamination status of heavy metals (Cu, Fe and Zn) along western coast of Bali Strait in Banyuwangi, East Java. Bali Strait is one of the many straits in Indonesia with high fisheries activities that could potentially contributed to high heavy metal pollution. There were five sampling areas from the north to south: Pantai Watu Dodol, Pantai Kalipuro, Ketapang Port, Pantai Boom and Muncar as the fish landing area. Heavy metal pollution in these locations comes from many different activities such as tourism, fish capture and fish industry and also domestic activities. Contamination factor (CF), geo-accumulation index (Igeo) and enrichment factor (EF) of each heavy metal were calculated to obtain contamination status of the research area. The concentrations of Fe were observed the highest (1.5-129.9 mg/kg) followed by Zn (13.2-23.5 mg/kg) and Cu (2.2-7.8 mg/kg). The distribution of Cu, Fe and Zn showed variability among the sampling locations in which high concentrations of Cu and Zn were higher in Ketapang Port, whereas high concentration of Fe was high in almost all sampling locations. According to the pollution index, contamination factors of Cu, Fe and Zn were low (CF < 1 and Igeo < 1). However, high index of EF (> 50) showed high influence of the anthropogenic activities to the contribution of the metals to the environment. This could also because of the high background value used in the calculation of the index due to the difficulties in finding background value from the sampling areas.Keywords: heavy metals, pollution index, contamination factor, geo-accumulation index, Bali Strait
The Ability of biofilter sponge demospongiae class with various forms of growth towards the turbidity and total suspended solid

Published: July 2019

The sponge is an invertebrate animal from phylum porifera that lives permanently and filters out what is in the water column. The sponge has various forms of growth, including massive, branching, and submissive. Each form of growth is indicated to have different filtering abilities, so this research needs to be done. This study aims to determine whether the ability to filter (biofilter) Turbidity and Total Suspended Solid sponge depends on the form of growth (Massive, Submassive, and Branching). This research was conducted from September to October 2016. Taking sponges in the waters of Barranglompo Island, testing was carried out at the Hatchery Marine Station at Hasanuddin University, Barranglompo Island and measurements of water quality parameters were carried out at the Chemical Oceanography Laboratory, Department of Marine Sciences, Faculty of Marine and Fisheries, Hasanuddin University. The acclimatization process needs to be done to adapt the sponge before being given treatment. Each aquarium is filled with seawater that has been mixed with sediments as much as 0.17 mg/l. Then each form of sponge growth is put into an aquarium with the same body volume of 500 cm3 and sees the ability to filter it for 10 hours and 24 hours. After that, water samples were taken at each aquarium to measure turbidity parameters, Total Suspended Solid, and Total Organic Materials. The results showed that at 10 hours and 24 hours the sponge with submassive growth forms filtered more particles in the water column than massive and branching growth forms, while sponge with branching growth forms run into stress and death after filtering for 24 hours.Keywords: growth pattern, biofilter, sediment, sponge.

The unique monomer and excimer fluorescence emissions of pyrene were first exploited as distinctly photophysical signals to identify the possible diastereomers of guests within nor-seco-cucurbit[10]uril (NS-CB[10]) cavities. Further experiments revealed that balancing the hydrophilic and hydrophobic effects of the guest in aqueous solution can improve the molecular recognition and binding ability of NS-CB[10].
