Fingerprint Database Enhancement by Applying Interpolation and Regression Techniques for IoT-based Indoor Localization
Authors: Suroso Dwi Joko , Adiyatma Farid Yuli Martin , Cherntanomwong Panarat , Sooraksa Pitikhate 
Published: January 2022

Most applied indoor localization is based on distance and fingerprint techniques. The distance-based technique converts specific parameters to a distance, while the fingerprint technique stores parameters as the fingerprint database. The widely used Internet of Things (IoT) technologies, e.g., Wi-Fi and ZigBee, provide the localization parameters, i.e., received signal strength indicator (RSSI). The fingerprint technique advantages over the distance-based method as it straightforwardly uses the parameter and has better accuracy. However, the burden in database reconstruction in terms of complexity and cost is the disadvantage of this technique. Some solutions, i.e., interpolation, image-based method, machine learning (ML)-based, have been proposed to enhance the fingerprint methods. The limitations are complex and evaluated only in a single environment or simulation. This paper proposes applying classical interpolation and regression to create the synthetic fingerprint database using only a relatively sparse RSSI dataset. We use bilinear and polynomial interpolation and polynomial regression techniques to create the synthetic database and apply our methods to the 2D and 3D environments. We obtain an accuracy improvement of 0.2m for 2D and 0.13m for 3D by applying the synthetic database. Adding the synthetic database can tackle the sparsity issues, and the offline fingerprint database construction will be less burden. Doi: 10.28991/esj-2021-SP1-012 Full Text: PDF

In this paper, we present some results obtained from the simulation of low power 633, 780, 850, and 940 nm laser in the liver by Monte Carlo method, with the model of the liver, consisting of 5mm derm, 7mm subcutaneous fat, 5 mm muscle layer. Based on these results, we fabricated devices called “Laser Semiconductor Optoacupuncture and phototherapy Device” using 780 and 940nm semiconductor lasers to treat chronic hepatitis. We combined with the doctor in An Giang province to clinical practice for 50 voluntary patients with chronic hepatitis. We used a 650 nm wavelength intravascular semiconductor laser treatment clinically to provide high-quality blood to the patients’ liver. Treating the phototherapy of the skin with two semiconductor laser beams with 780 nm and 940 nm wavelengths directly affects the liver from the surface of the abdomen. At the moment, we use the treatment on acupoint with 940nm- wavelength laser. A treatment course consists of 20 times for the patients is treated continuously. The patients tested with the ALT and AST before and after treatment with 3 courses. We use the SPSS 23 statistical method to evaluate the outcomes of treatment. The clinical symptoms of the patients such as fatigue, nausea, indigestion, fever, jaundice, yellow eyes almost completely have gone out after treatment. Low-level laser therapy offers a good response in patients with moderate to severe hepatic impairment such as the AST of 56.380 ± 10.162 and 39.260 ± 4.869; The ALT of 56.540 ± 13.580 and 41,360 ± 7,488 for before- and after treatments, respectively. Low-level laser therapy for patients initially has good results, high therapeutic effectiveness, no catastrophic or side Effects, and the statistical significance is p &lt; 0.001.This research applied the ethical principles of the Helsinki Declaration in human researches. The research was carried out using non-invasive methods on humans with the regulations of the University of Technology, Vietnam National University Ho Chi Minh City, and the relevant regulations.

Published: January 2022

The cancer of breast is virulence in female and is curable in ~70–80% of patients. The vitamin type C is an essential vitamin and consider as an anti-oxidant, so this vitamin could recover the supply for oxygen, stopping the destroy of DNA and other impact necessary in cancer processing. The vitamin C indicate as an active anticancer as the concentricity were monitor in this cancer therapy. The concentricity of this vitamin has a main function in cancer-rising or cancer suppression. These studies have shown a relationship between the vitamin and increase death-rate of breast cancer, so it’s important to detect the anticancer prospective of vitamin C to detect the different among its effect in healthy and damage cells, especially these studies conducted that this difference could depend on the vitamin c concentration. These studies indicate that large doses of vitamin c could decrease the effect of some cancer therapy such as radiation and chemotherapy.

Published: January 2022

Medicinal plants produce great groups of secondary metabolites which are essential for medicine purpose, one of them phenolic compounds, antimicrobial activity of phenolic compounds which derivative from plants has been examined for several years. The phenolic extracts of Sesamum indicum and Pimpinella anisum seeds have antibacterial action against Gram positive (Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli), (Acinetobacter baumannii), and (Pseudomonas aeruginosa) (Proteus mirabilis). The current findings show that the synergistic impact of phenolic extracts from S. indicum and P. anisum is active against a variety of pathogenic bacteria, and that the synergistic effect for two plants is more antibacterial than phenolic extracts from one plant. The results indicated Gram- negative (P. aeruginosa) more effected by plants, than Gram-negative (S. aureus) which have the lower effects. The results of HPLC indicated Sesame (S. indicum) have total concentration of phenolic compounds was (1313.7 µg/ml) higher than total concentration of phenolic compounds of Anise (P. anisum) (220.991 µg/ml), and have varied types of phenolic compounds were Pyrogallol, Gallic acid, Rutin, Kaempferol, Cinnamaldehyde, Qurctin, Eugenol, Lignan with different concentration. From this study may be conclusion Synergistic effect for two plants have more antibacterial than phenolic extracts of one plant, and Sesame (S. indicum) have higher antimicrobial activity than Anise (P. anisum).

People's interest in the safe use of food has existed since ancient times, so that even today there is a global demand for the production of food that can be used without risk to health. Contaminants, as well as the type and location of grazing can affect the physico-chemical and sensory properties of honey. The aim of the study was to examine the microbiological validity and sensory properties of honey from two different areas in Tuzla Canton. The research included three samples of forest honey from the Kladanj area and three samples of flower honey from the Lukavac area. In addition to microbiological analyzes and sensory properties, the concentration of HMF in honey was determined as an indicator of heating and inappropriate storage of honey. All samples were microbiologically correct.
The sample of flower honey L1, which did not meet the criteria prescribed by the Regulation on Honey and Other Bee Products, was not sensory evaluated. L1 sample was not sensory evaluated due to an increased HMF content of 105.38 mg/kg.
Based on sensory analysis, the samples of flower honey from Lukavac were better evaluated than forest honey from Kladanj. Statistical analysis showed that there is a significant difference between the mean values for the sensory properties of purity and color.

Authors: Thapa Pradip , Thapa Divas , Sharma Anup 
Published: January 2022

Introduction: Laparoscopic cholecystectomy is the gold standard treatment for cholelithiasis. Postoperative shoulder tip pain is common complaint. Evidences suggest that using low pressure pneumoperitoneum (8-10 mmHg) during the procedure rather than standard pressure (12-14 mmHg) decreases the incidence and severity of shoulder tip pain without compromising working space.
Aims: The aim of this study was to evaluate the impact of low pressure and standard pressure pneumoperitoneum on shoulder tip pain post laparoscopic cholecystectomy.
Methods: A prospective hospital based study conducted at Nepalgunj Medical College, Kohalpur from January 2019 to December 2020. Hundred patients were enrolled, fifty each in “low pressure carbondioxide pneumoperitoneum” and “standard pressure carbondioxide pneumoperitoneum” groups, who underwent laparoscopic cholecystectomy. The two groups were compared in terms of incidence and severity of shoulder tip pain, surgeon’s satisfaction score, top-up analgesia requirement, procedural time, conversion to standard pressure, intraoperative complications and length of hospital stay.
Results: There were 45 (90%) females and five (10%) males in low pressure group and 44 (88%) females and six (12%) males in standard pressure group. Fourteen (28%) patients in low pressure and 32 (64%) patients in standard pressure group had shoulder tip pain (p=0.001). The severity of shoulder tip pain was less in low pressure group and was significant at eight hours (p=0.006) and 12 hours (p=0.008). Top-up analgesia was required more in standard pressure group. There were no intraoperative complications but only one conversion to standard pressure. Surgeon’s satisfaction score, conversion to open cholecystectomy and procedural time were comparable in both groups with shorter hospital stay in low pressure group.
Conclusion: Low pressure carbondioxide pneumoperitoneum is safe and effective strategy in reducing incidence and severity of shoulder tip pain after laparoscopic cholecystectomy.

Introduction: Surgical treatment of thoracolumbar fracture without neurological damage has resulted in better clinical and radiological outcome than conservative treatment. Traditional open approach is associated with extensive paravertebral muscle damage and postoperative morbidity so percutaneous pedicle screw fixation is highly valuable alternatives.
Aims: to evaluate the efficacy and outcome of percutaneous pedicle screw fixation in the treatment of traumatic thoracolumbar fracture without neurological deficit.
Methods: This study was conducted in Nepalgunj Medical College, Nepalgunj in a time span of one year; total of 40 patients were included and treated with percutaneous pedicle screw fixation and followed up for 6months. They were evaluated clinically and radiologically.
Results: 40 patients with thoracolumbar fractures were managed with percutaneous pedicle screw fixation with a mean operative time of 77.30 min and intraoperative blood loss was 88.38ml. There was significant improvement in cobb’s angle (mean difference 13.92 degree), vertebral body height loss (mean difference 37.7%) and visual analogue scale (mean difference 3.55) postoperatively. These improvements remained statically significant at 6months follow up.
Conclusion: Percutaneous pedicle screw fixation is safe, valid and effective treatment of thoracolumbar fracture without neurological deficit.

Introduction: Molar pregnancies represent a significant burden of disease on the spectrum of gestational trophoblastic diseases. Vaginal bleeding being the most common occasionally, molar pregnancy is complicated by hyperthyroidism, which may require treatment.
Aims: To determine thyroid function test and association of hyperthyroidism among the cases of molar pregnancy.
Methods: This is a hospital-based cross-sectional study conducted in the department of Obstetrics and Gynecology, Nepalgunj Medical College and Teaching Hospital, Kohalpur. Sixty cases of molar pregnancy were included during the study period from February 2020 to January 2021.Patients having history of known thyroid disorders were excluded.
Results: Prevalence of molar pregnancy in our study was 5.4 per thousand pregnancies in our hospital. Molar pregnancy and hyperthyroidism, both were common in the age group of 21-35 years. Hyperthyroidism was present in 10% patients. Enlarged thyroid was seen in 3.3%, tremor was present in 3.3%, and palpitation in 21.5%. Five (8.3%) patients with hyperthyroidism were underweight. Majority of patients with hyperthyroidism, beta humanchorionic gonadotrophhin level was more than three lakhs and it was mostly associated with complete hydatidiform mole compared to partial hydatidiform mole. Thyroid storm was not experienced in any of the patients.
Conclusion: The rate of molar pregnancy is high. Hyperthyroidism in molar pregnancy is not uncommon. High levels of human chorionic gonadotropin, complete hydatiform mole are directly associated with hyperthyroidism. Awareness of this condition is important for diagnosis and treatment to prevent life threatening complications.

Authors: Khan Feeroz Alam , Maharjan Prabir 
Published: January 2022

Introduction: Undescended testis is one of the commonest presentations in pediatric population. Conventionally, high ligation of the hernia sac was done after vas and vessels were dissected in order to prevent post-operative hernia. However, recent studies have shown that hernia sac ligation was unnecessary.
Aims: To evaluate the role of hernia sac ligation during orchidopexy to prevent the development of postoperative hernia and to compare the mean operative time with and without sac ligation.
Methods: A prospective comparative study was conducted with a total of 94 patients with undescended testis, age ranging from six months to 16 years were included in the study from November 2018 to May 2021. Cases were randomly divided into two groups. In Group A cases, orchidopexy was carried out with sac ligation, while in Group B, the hernia sac was not ligated. Mean operative time was recorded in each case. All the patients were followed up at one, four and eight weeks post-operatively and examined for postoperative hernia.
Results: Of the total 94 cases, there were 18 bilateral and 76 unilateral cases of which 56 were right-sided and 22 left-sided. Most of the patients (45) of the study were between six months and 2 years. None of the patients of either group developed post-operative hernia or any significant complications. The mean operative time for group A and B were 36.72 and 46.96 minutes respectively.
Conclusion: It was concluded that ligation of processus vaginalis was unnecessary during orchidopexy and sac ligation consumed more operative time.

Authors: Adhikari Jyoti , Belbase Mohan , Rijal Shikha 
Published: January 2022

Introduction: Anemia is one of the most prevalent nutritional deficiency problem affecting pregnant women. It is defined by World Health Organization as hemoglobin (Hb) level of less than 11 g/dl. Hemoglobin level of 9.0- 10.9 g/dl is mild, 7.0-8.9 g/dl is moderate and less than 7 g/dl is severe anemia respectively. Maternal anemia in pregnancy is commonly considered as a risk factor for poor pregnancy outcome and can result in complications that threaten the life of both mother and fetus.
Aims: To find out neonatal outcome delivered to anemic mothers.
Methods: A prospective case control study was carried out among 75 newborns delivered to pregnant women with hemoglobin below 10.9g/dL. Another 75 newborns were taken delivered at the same time, matched age and sex wise as a control group to mothers whose hemoglobin was more than 11g/dl.
Results: Out of total 75 cases 35(46.7%) mothers had mild, 32(42.6%) had moderate and 8(10.7%) had severe anemia respectively. Similarly, the risk of having preterm baby among anemia group was 4.42 times higher than that in control group (p 0.033). The risk of having low birth weight in anemia group was 3.9 times higher than that in control group (p 0.04). The mean of head circumference (HC) among the anemia group was 33.9cm +1.40 (Mean+SD) and among the control group was 34.4cm+1.24(Mean+SD) with a mean difference of 0.5cm (p 0.032). The mean of length among anemia group was 45.3cm+1.97 (Mean+ SD) and among the control group was 46.2cm+1.69 (Mean+ SD) with a mean difference of 0.9 cm (p 0.003).
Conclusion: Maternal anemia in pregnancy is associated with increased risk of adverse neonatal outcome. Efforts must be made to reduce the prevalence of anemia especially during pregnancy to reduce neonatal morbidity and mortality.
