Published: March 2021

Objective – Library anxiety experienced by students has been discussed extensively for many decades. While the phenomenon is widely recognized, little attention has been paid to seeing its specific effect on marginalized sections of the society. The study attempts to understand the library anxiety experienced by students at three different universities in Assam. Assam is the only state in Northeast India to have private, state, and central universities. These universities draw their student populations from several different hill states in Northeast India, all of which face significant socio-political-economic challenges.
Methods – A stratified random sample technique was used for the study. A total of 150 questionnaires were distributed equally among the three universities in Assam and found 119 questionnaires were fit for analysis. The study adopted the modified and validated version of the Bostick Library Anxiety Scale developed by Anwar, Al-Kandari, and Al-Qallaff (AQAK) in 2004, with 32 item statements and 4 categories. The questionnaire is divided into two parts: Demographic Variables and the Library Anxiety Scale. The categories used for the study were: Category 1 (Staff Approachability) – 11 statements; Category 2 (Feelings of Inadequacy) – 6 statements); Category 3 (Library Confidence) – 8 statements; and Category 4 (Library Constraints) – 7 statements.
Results – The study hypothesized that factors such as gender, the language of instruction, type of university, and caste or community do not influence library anxiety among Northeast India students. However, the study's findings suggest that type of university influences library anxiety among students and its three constructs. Tezpur university students experience a higher level of library anxiety. Although no overall significant difference in the level of library anxiety was observed among students across gender (p=0.278, p> 0.05), the language of instruction (p=0.023, p> 0.05), castes and communities (p=0.223, p> 0.05), there was a significant difference in one construct of library anxiety among students based on gender (feelings of inadequacy), the language of education instruction (staff approachability), caste and community (feelings of inadequacy).
Conclusions – Results from the present study provided compelling evidence to suggest that many students, irrespective of their gender, the language of instruction, type of university, discipline, and caste or community experience library anxiety. The difference levels of library anxiety among independent variables indicate a critical lack of information literacy skills. Overall, library anxiety scores among the students were moderate; some categories such as staff approachability, the feeling of inadequacy, and library constraint are the attributes of the students' anxiety. However, the findings of the study also suggest that students are confident in using the library. They are optimistic, enthusiastic, and keen to use library resources.

In the management of symptoms created by breast cancer (BC), pain is the most important. So, this study aimed to evaluate different dimensions of pain in patients using the McGill Pain Questionnaire. In this way, physicians could perform effective treatment for patients.

Methods: This case study was done on BC patients aged 30-60 years old in some specialized cancer hospitals in Tehran. The utilized research instrument in this study was the McGill Pain Questionnaire. Data were analyzed by SPSS Software.
Conclusion: According to these results, it is possible to use effective and better treatment to reduce BC patients’ pain.

Published: March 2021

Background: Imaging, cytological examination of ascites (if present), laparosco- py, and peritoneal lavage are performed before surgery for gastric cancer staging. Peritoneal lavage aims to diagnose the microscopic presence of tumor cells on the peritoneal surface. Positive cytology may have a prognostic value that classifies the disorder as stage IV, in which the patient is no longer an elective surgical candidate. Thus, our study was designed to assess the ability of peritoneal lavage to stage gastric cancer in non-ascitic patients based on cytological evaluation and carcinoembryonic antigen (CEA) level measurement.
Methods: In our prospective study, we examined gastric cancer patients who were candidates for elective surgery. Upon entering the abdominal cavity and before tu- mor manipulation, normal saline (500 ml) was applied, and the abdominal cavity was thoroughly dispersed. After three minutes, the fluid was drained and addressed to cytological analysis and CEA measurement by radioimmunoassay (RIA). Study var- iables including age, sex, family history, tumor position, pathology, staging, grading, the original tumor size, regional lymph node involvement, and distant metastases were recorded during the pre- and postoperative staging. The association between positive peritoneal lavage cytology and various patients’ characteristics was investigated.
Results: In this study, 94 patients were screened. Due to lymphoma and gastrointes- tinal stromal tumor (GIST), two patients were excluded. We examined 92 patients, including 63 males (68.5 %) and 29 females (31.5 %). The mean age of patients was 58.52 ± 11.87 years. The most common tumor location was the esophagogastric junction. Moderately differentiated adenocarcinoma was the most frequent micro- scopic diagnosis. T3 was the most prevalent primary tumor size in 51 patients. Sev- enty-two patients (78.26%) were operable, of whom 18 (19.6 %) were positive for peritoneal lavage cytology. Positive cytology of peritoneal lavage was significantly related to tumor size, tumor grade, serosa/adjacent organ invasion (T4), laparoscopic staging findings, locally advanced disease (R0), and stage of the disease (P < 0.05). In the peritoneal lavage fluid, elevated CEA titers were significantly related to the high-grade tumor (P = 0.012).
Conclusion: Our study demonstrated that positive cytology and high CEA titers in peritoneal lavage fluid of gastric cancer patients without ascites are significantly correlated to the advanced stages.

Fouling merupakan salah satu kendala yang membatasi kinerja membran ultrafiltrasi (UF). Keberadaan Bahan Organik Alami (BOA) menjadi penyebab utama terjadinya fouling membran pada air gambut. Pra-perlakuan adsorpsi mampu menjadi solusi untuk mengurangi fouling dan meningkatkan performa membran UF polisulfon (UF-PSf). Penelitian ini bertujuan untuk menyelidiki pengaruh pra-perlakuan adsoprsi terhadap perubahan nilai fluks pada membran UF- PSf, dan menganalisis model pembentukan fouling yang paling tepat untuk menggambarkan proses hibrid adsorpsi dan UF-PSf. Proses hibrid adsorpsi dan UF-PSf dilakukan pada kondisi optimum dengan pH 4 dan dosis optimum Powdered Activated Carbon (PAC) 1040 mg/L pada tekanan 1-3 bar. Tekanan operasi terbaik terjadi pada tekanan 3 bar dengan nilai fluks permeat sebesar 85,064 L/m2.jam dan rejeksi BOA sebesar 85,24% (UV254) dan 85,07% (KMnO4). Modified Fouling Index (MFI) merupakan pemodelan yang tepat untuk menggambarkan pembentukan fouling pada proses hibrid adsorpsi dan UF-PSf pada penyisihan BOA air gambut. Tekanan 1 bar memiliki potensi fouling yang tinggi dengan nilai R2 sebesar 0,998.

Beberapa permasalahan yang dapat timbul dari meningkatnya pertumbuhan penduduk dan pertumbuhan ekonomi ialah meningkatnya jumlah sampah di Kabupaten Banjar, sebagian besar sampah dapat menyumbang GRK dalam bentuk gas metana (CH4). Sampah yang tanpa sengaja tertimbun dalam jangka waktu tertentu bisa mengalami atau terdekomposisi serta dapat menghasilkan gas-gas yang pada akhirnya akan tersebar di udara. Oleh karena itu, perlu dilakukan pengelolaan sampah yang tepat dan ramah lingkungan agar tidak mencemari dan merusak lingkungan. Menggunankan metode WARM (Waste Reduction Model) ialah aplikasi yang berfungsi untuk menghitung emisi GRK dari sektor persampahan dengan memasukan data yang telah diperoleh ke dalam aplikasi. Hasil analisis dari penelitian yang telah dilakukan adalah keberadaan bank sampah mampu mengurangi emisi GRK yang dihasilkan pada aktivitas penimbunan sampah secara langsung di TPA yang dapat terlepas ke atmosfer dalam jumlah besar, apabila kegiatan bank sampah atau pengelolaan sampah lainnya benar –benar dioptimalkan.
