Authors: Siagianto Bambang Eko 
Published: September 2017

Abstracts: Sub-ordinate conjunction is very confusing to comprehend by students. In using sub-ordinate conjunction, students usually had errors. The purpose of this research to analyze whether or not the students are able to use sub-ordinate conjunction in sentence writing, to classify kinds of sub-ordinate conjunction that was often misused by students in sentence writing The research was done at the grade XII of SMA N 2 Metro in second semester of the academic year 2013/2014. The predicted research findings are; the students cannot divide or difference the type of sub-ordinate conjunction well, and they often errors using it in sentences.The result of the students test in using sub-ordinate conjunction in sentence writing proves that most of the students at the grade XII of SMA N 2 Metro used the list of words “after, then, when, because” on their sentence writing. The students found these words easier to be used as conjunction especially sub-ordinate conjunction in their sentence writing than other conjunction. While, for other list of words doesn’t used by the students because the students cannot adapted the words in their sentence writing. The most familiar sub-ordinate conjunction seems to be “before and since” (each of them is gained by 22 students = 91,6%), but the students are unfamiliar with the other words in sub-ordinate conjunction mainly “till and unless” (each of the is gained by 13 students = 54,1%). The other sub-ordinate conjunctions are quite familiar for them.

Abstract : Character education plays an important part because it is not only about moral and value education. It has a higher significance of moral education, because it not only teaches what is right and what is wrong. More than that character education inculcate the habit (habituation) about good things and wrong, can feel (affective domain) good value and used to do (behavioral domain). So the character education linked closely associated with persistent habits practiced or implemented. It is commonly believed that the practices of English language teaching always accompanied by the insertion of foreign cultural values which are not always in line with Indonesia cultural values. The aim of this study is to improve students’ writing skill through integrating local culture material. Therefore this study focuses on designing and evaluating teaching writing material for English department students of University Muhammadiyah Metro. The result of this study shows that students have big interest and motivation in writing a text based on their local culture. The students also get moral value and character building through the material. It influences the students’ character in their daily life. Students become more polite, honest, diligent and religious.

TEACHING LEXICALLY FROM VERTICAL LISTS TO HORIZONTAL ALTERNATIVES
Authors: Subandowo Dedy 
Published: September 2017

Abstract Teaching vocabulary for young learners by giving it into semantic set will not help them understand how the words are used. In elementary coursebook, the vocabulary is presented in list semantic set that is semantically related items such as jobs doctor, teacher, lawyer etc. or colours: red, blue, yellow etc.). This idea is really restrictive to develop the students’ vocabulary mastery. It seems that teaching vocabulary in semantically related items is counter-productive but this idea has never been taken on board. The question is Why do students have to go through so much learning of things which they are hardly ever likely to say?. (Estatiev, 2015) and (Leoselivan, 2014) introduce the way to teach students’ vocabulary by developing the students’ idea through communicative purpose beyond the basic description. Developing alternatives in horizontal lists instead of semantic set lists will make learners find the words in which they are likely to go with (co-text) rather than with other words sharing the same superordinate concept. The easy samples are colour and animal. Focusing them in three at a time and present would be more affective to fix the word collocation such as noun that can go along with adjective or noun collocation.

Authors: Liu Chengyao , Zheng Ming , He Fei , Wang Xiangdong , Zhang Luo 
Published: September 2017

Background Chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP) nasal polyps is a global health concern. Several clinical biomarkers, such as inhaled carbon monoxide and exhaled nitric oxide (NO), have been studied to assess the presence and degree of inflammation in the airway mucosa. Objective To evaluate the clinical application of exhaled nasal NO (nNO) in distinguishing between CRSwNP and CRSsNP in consideration of the atopic status of patients. Methods Eighty-eight patients with CRS and 20 healthy volunteers were recruited for this study. The exhaled nNO level was measured by using a hand-held device. Nasal endoscopy (with Lund-Mackay scoring of CRS) and sinus computed tomographies (CT) were used to evaluate the nasal cavity and sinuses of the subjects. Atopic status was confirmed by using skin prick tests (SPTs). Results The mean ∓ standard deviation (SD) levels of nNO in patients with CRSsNP were significantly higher than those in patients with CRSwNP (591 ∓ 153 ppb versus 360 ∓ 181 ppb, p <0.001), whereas patients with CRS exhibited lower levels of nNO compared with the control subjects (449 ∓ 204 ppb versus 881 ∓ 161 ppb, p <0.001). Patients with atopy and with and without nasal polyps exhibited significantly higher levels of nNO compared with patients without atopy (atopic CRSsNP versus nonatopic CRSsNP, 734 ∓ 220 ppb versus 503 ∓ 92 ppb [p <0.001]; atopic CRSwNP versus nonatopic CRSwNP, 518 ∓ 161 ppb versus 299 ∓ 150 ppb [p <0.001]). The levels of nNO were negatively correlated with the Lund-Mackay scores in both atopic (r = -0.45; p = 0.016) and nonatopic (r = -0.600; p <0.001) patients with CRS. Receiver operating characteristic curves differentiated patients as CRSwNP, CRSsNP, and healthy controls, and in atopic and nonatopic subgroups, with acceptable sensitivity and specificity (>70 to 90%). Conclusion Exhaled nNO levels can be used to distinguish between patients with CRSwNP and patients with CRSsNP. However, the atopic status of the patient influenced the use of nNO as a diagnostic or monitoring biomarker in CRS.

Published: September 2017

Steam and electricity needs in the paper industry have been provided itself through coal-fired boiler equipped with emission control devices. Boiler flue gas emissions of coal combustion products contain contaminants such as particulate emissions , NO2 and SO2 , and a small amount of emissions of mercury (Hg). Valuation on boiler emissions quality associated with air emissions control systems and emissions standard has been carried out. Estimation of mercury concentration in air emissions of boiler flue gas in the paper industry has also been conducted. The valuation on the air emissions quality of non-mercury parameters of paper industry boilers has also been done based on national emissions standards. The results of the valuation indicated that the current applied of flue gas emissions control devices in the paper industry has been optimally operated so that the emission quality of boiler for both non-mercury parameters and mercury parameters has been complied with the emission quality standards. Prediction of mercury content in air emissions of a coal boiler stack of paper industry that is discharged into environment based on the content of mercury in coal is 0.0205 mg/Nm3 (20.5 µg/Nm3 ) maximum. Paper industry needs to consider the application of co-benefit technology when mercury is used as a quality standard emissions parameter.
