Utilization of Location-Based Services Using Augmented Reality Perception Method For Android Based School Search

Data technology has become the main means for activities in various sectors of life, one of which is location-based services for SMA/SMK schools in the Bangka Belitung area. By using a location-based service application, it is expected to be able to overcome the problem of finding the position of SMA/SMK in the Bangka Belitung area. In this study, we would like to discuss the search for SMA/SMK positions. Through the push, Location-Based Service will be displayed in the smartphone, which will help identify the presence of the school's position on the smartphone. The result of the application that is formed is an Android-based application that can recognize the presence of SMA/SMK positions. This study aims to create a location-based service application that is combined with the concept of overlaying geographic position information from augmented reality perception, which is one type of augmented reality. The overall application quality test results include 1). Based on the Functionality aspect, the percentage of the actual score got a total score of 91.8%. 2).

Realistic Dilemma and Solution of “Vocational Skill Test” under the Background of Enrollment Reform of Classified Examination in Higher Vocational Colleges in Jilin Province

In the process of Higher Vocational classified examination enrollment reform, Jilin Province has adopted a diversified examination enrollment model and “cultural quality test + vocational skill test” evaluation method, and established the “vocational education college entrance examination” system. This paper analyzes the important role and practical difficulties of “vocational skill test” in Higher Vocational classified examination, studies the existing problems, and puts forward to reasonably divide the proportion of “cultural quality test” and “vocational skill test”, sets diversified admission standards, scientifically sets up the assessment methods and contents of “vocational skill test”, further improves the “cultural quality test + vocational skill test” evaluation method and builds a classified examination and enrollment system more in line with the characteristics of vocational education.

EVALUATION OF PREDICTIVE CAPABILITIES OF TIRADS, EU-TIRADS, TLA_RU SYSTEMS IN THE ULTRASOUND DIAGNOSIS OF THYROID NODULAR PATHOLOGY

The aim of the study was to evaluate the prognostic capabilities of EU-TIRADS, TIRADS, TLA_RU systems in ultrasound diagnostics of thyroid nodular masses. A retrospective independent continuous blind study of ultrasound examination protocols was conducted in 665 patients, 241 patients had benign non-cancerous thyroid diseases, 86 patients had benign tumors (adenomas), 338 patients had thyroid cancer. During the preoperative examination, all patients underwent a multiparametric ultrasound examination of the neck organs according to the standard procedure, with the registration of identified thyroid nodes, with examining the prognostic capabilities of stratification systems – TIRADS, EU-TIRADS, TLA_RU. It was found that the TIRADS system has a sensitivity of 91.04%, specificity – 91.41%. Focusing on the scale of AUC values reflecting the quality of the diagnostic test, it can be stated that TIRADS is a test with excellent quality (AUC =0.972). Basing on the results of the analyzing the data obtained by the EU-TIRADS system, it was revealed that it is a high-quality test (AUC=0.826), but its predictive capabilities are worse than those of TIRADS. The original TLA_RU model has 87.5% sensitivity and 95.7% specificity. During the ROC analysis, it was found that the AUC is equal to 0.954±0.00894, which suggests that the TLA_RU model is an excellent quality test in the differential diagnosis of thyroid nodular masses. Multivariate statistical comparative analysis of thyroid imaging assessment systems (TIRADS, EU-TIRADS and TLA_RU) from the standpoint of evidence-based medicine has shown that thyroid cancer risk stratification systems based on the assessment of multiparametric ultrasound signs have great diagnostic capabilities.

Research on Civil Aircraft Flight Test of Power Supply Quality Analysis

In the process of civil aircraft airworthiness, analyzing power quality is the key to verify whether the power supply system meets the requirements of the clause.

Then, comparative and analysis give suggestions which tally with power supply quality test requirements. Finally, define the special power supply quality test method for the practical engineering specifically, and power supply quality test characteristic in civil aircraft flight test, to provide guidance help for the future civil aircraft models.

Validation of Climate Hazard Group InfraRed Precipitation with Station (CHIRPS) Data in Wonorejo Reservoir, Indonesia

This study aims to test the validation of precipitation data from CHIRPS compared to measurement data. The study location is Wonorejo Reservoir, Indonesia. The methods in this research were 1) data quality test with the consistency test and stationary test, and 2) validity test with parameters of NSE value and correlation. The study results show that 1) The data quality test shows that the precipitation data from CHIRPS are consistent and homogeneous; 2) The validity test is carried out in two stages, for uncorrected data and corrected data. According to NSE value, the validity of test results on uncorrected data shows that CHIRPS’s precipitation data are unsatisfactory. When viewed from the correlation, the precipitation data from CHIRPS has a very strong relationship to precipitation measurement data. The next step is to test the validity of the corrected data. The validation test of corrected data shows that precipitation data from CHIRPS is satisfactory according to NSE value. Moreover, the precipitation data from CHIRPS strongly correlates with the precipitation measurement data. This study indicates that the precipitation data from CHIRPS can be utilized as alternative precipitation data if measurement data are limited.

Preparation and Antimicrobial Activity Analysis of Organic Soap Bar Containing Gnetum gnemon Peel Extract

Melinjo (Gnetum gnemon L.) peel has been known as antioxidant, antibacterial, and antifungal, but not yet used as cosmetic ingredients or drugs optimally. This research focuses on the production of organic soap bars from melinjo peel extract, the quality testing, and antimicrobial analysis against selected microbes. The soap making process was done by the saponification reaction between the mixture of palm oil and coconut oil with sodium hydroxide through cold and hot processes. Distilled water and ethanol were used as solvents for melinjo peel extraction. The quality test was done by determining insoluble fraction in ethanol, free alkali, and unsaponified fatty matter. An antimicrobial activity test was conducted using the Kirby-Bauer diffusion method. The result shows that the quality test fit with INS 2016 for all the criteria except for unsaponified fatty acid in the cold process soap bar. Inhibition zone of organic soap bar sequentially decreased against the growth of Tricophytone mentagrophytes, Staphylococcus aureus, and Staphylococcus epidermidis. Therefore, the organic soap bar with melinjo peel extract shows a good potential to be used as an antimicrobial soap.
