In order to gain the biogas production potential from Oxalis corymbosa, the anaerobic batch fermentation which were divided into the control group (120ml inoculum), the experimental group (120ml inoculum and 125g Oxalis corymbosa) were performed at 30°C. The results indicated that the net biogas production of the experimental group during total fermentation time of 50 days was 3220 ml. Further, it was calculated that the biogas yield of Oxalis corymbosa was 338ml/g TS or 388ml/g VS. The result indicated that Oxalis corymbosa can be used for biogas fermentation and the fermentation production potential was good.

This paper studies on the biogas production yield of which use the lily straw as raw material and the fermentation is batch by batch at 30°C. In the third day of fermentation, fermented liquid became acidic. But it can be back to normal with the action of the anaerobic microbe. Its biogas yield is higher than the other group to adjust pH value. So gas production potential of the lily straw is 475ml/gTS and 573ml/gVS with 31 days of anaerobic digestion. The volumetric biogas production rate reaches 0.19ml/ml/d.

Early childhood is a formative period during which healthy habits are developed, including proper hand hygiene practices. The aim of this quasi-experimental study was to determine the effectiveness of a 4-week series of educational sessions that consider the cognitive developmental stage of children on increasing their knowledge and promoting hand hygiene practices. The intervention group (n = 33) observed the hand hygiene program, whereas another group served as the waitlist control (n = 20). Creative activities were planned for the illustration of hand hygiene concepts in terms of “right moments”, “right steps”, and “right duration”. Hand sanitizer coverage was evaluated using a hand scanner. After the intervention, the experimental group had higher knowledge level toward hand hygiene than the control group (p < 0.001). Significant improvements in hand hygiene performance at the left palm and dorsum (p < 0.05), right palm (p < 0.05), and overall hand coverage (p < 0.05) were observed in the experimental group. The study demonstrated that the knowledge and proper hand hygiene (HH) practice of children can be positively influenced by the use of an age-appropriate education program. The results of this study have implications for school health educators and parents for promoting HH practices among children at home and at the school level.

This is an experimental study in the area of Didactics applied to the learning of English as a foreign language and complemented by CALL. The main objective of this work is to know the degree of incidence existing between two groups of students: one, based on conference-style classes where students, guided by the teacher, have to search for information about a topic in the computer lab and present it in front of the class and, in the other, where students are taught by the teacher according to a printed text. The experimental design consisted of a pre-test/post-test plus the application of different techniques to develop the different linguistic and cognitive strategies, between these tests. The methodology used by the Experimental Group forced learners to generate their own knowledge, so they had to apply the information and work by themselves in Workshops; and the Control Group participated in the classroom according to the communicative approach, guided by the teacher in the traditional class. Statistics were applied to the scores obtained between both tests, and the scores obtained weekly in the different competences contributed to knowing whether there were significant differences between both groups.

The purpose of this study is to develop and apply a type of perineal underwear that protects the patient’s physical privacy and to examine its effects on perineal discomfort and shame. This study collected primary data from 44 patients who visited Kyung Hee University hospital in Seoul city and were admitted to the neurosurgery ward to undergo angiography between 7 August 2017, and 30 April 2018. In this quasi-experimental study with a nonequivalent control group posttest-only design, participants were divided into an experimental group (n = 22) and a control group (n = 22). The control group used conventional protection, which involved wearing padding around the perineum, while the experimental group wore the perineal underwear developed in this study. The underwear group showed a significantly lower degree of shame (Z = −5.39, p < 0.001) and perineal discomfort (Z = −5.88, p < 0.001) than the padding group. In the padding group, women felt significantly more shame than men did (Z = −2.48, p = 0.013). The use of the perineal underwear developed in this study significantly reduced the degree of shame and perineal discomfort in patients undergoing angiography. Such perineal underwear could also be useful for protecting patients’ privacy during perineal examinations.

Objective: To evaluate the effect of therapeutic exercises on pregnancy related low back pain in a tertiary care hospital of Karachi. Material & Methods: This was a quasi-experimental study with non-probability convenience sampling technique. Study was carried out at Liaquat National Hospital Karachi. Patients were divided into two groups (Experimental and Control). Inclusion criteria were age <30 years, 2nd and 3rd trimester, stable medical status and those who gave the informed consent. Exclusion were pregnancy induced hypertension (>140/90mmHg), Cardiac disease, diabetes mellitus, persistent vaginal bleeding, history of miscarriages, decreased foetal movement. Data was collected through assessment Modified Oswestry Low back pain disability questionnaire. SPSS version 23.0 was used to analyze the data. Results: A total of 30 samples were selected for the study. There were 15 respondents in experimental while 15 in control group. Disability levels were found to be significantly decreased after post treatment in experimental group with P-value= 0.002. It was seen that number of patients was increased from 1(6.7%) to 6(40%) in minimal disability group whereas crippled back pain group in pre-treatment group was totally shifted towards minimal or moderate pain 3(20.0%) and no case was seen in post-treatment. Conclusion: Low back pain in pregnancy can disturb daily life routine but exercise therapy and proper counselling will lead stress free life to female in gestation. After post treatment in experimental group showed decrease in pain as compare to control group who were not provided any exercise therapy. Working women in experimental group also showed decrease by crippled back pain to moderate pain after exercise. So in the end researcher suggest that physiotherapy exercises play a vital role in reducing Low Back Pelvic Pain (LBPP) during pregnancy.

This research is aimed to find out the effect of definitions toward students’ vocabulary mastery: it was an experimental study at the second grade student of MTs NW Haqqul Yaqin Sayang- sayang. The subject of this research was the second grade of MTs NW Haqqul Yaqin Sayang- sayang.The research was used experimental method with quantitative approach. The population of this research consist of 55 students, and the sample is 29 for experimental group while 26 for control group. The technique of collecting data was used definition for experimental group and matching word with antonym for control group. The data was collected by using post-test only and the data was analyzed by t-test formula. Based on data analysis the mean score of experimental group was 76,4 and control group was 69,23, beside of that standard deviation for experimental group was 114,28 and for control group was 113,09 and the value of t-test was 2,44 and t-table was 2,000. Degree of freedom is 53 with significant level 0,05. It means that the value of t-test was higher than t-table (t-test ˃ t-table). The alternative hypothesis (Ha) was accepted and null hypothesis (Ho) was rejected. Thus, the conclusion of this research was there was an effect of definition toward students’ vocabulary mastery: an experimental study at the second grade students of MTs NW Haqqul Yaqin Sayang-sayang.
