Alas M, Sali,Doddy Ferdiasyah 한국정보통신학회 2021 2016 INTERNATIONAL CONFERENCE Vol.12 No.1

The results of research on the level of community literacy in Kasomalang Village regarding information technology are still low.[4] To be able to support the goal of developing the smart village concept, preliminary research is carried out first so that the community is familiar with it, and the infrastructure and data requirements for the intelligence system can be provided. One of the preliminary research that was carried out was building an SMS-gateway to capture data on complaints patterns of Kasomalang villagers, which could later be processed by the intelligence system. The result of this research is an SMS-gateway application and its infrastructure support to help public complaint services by utilizing GSM & cellular phones, and the ease with which village officials can get data from community complaints.

Hamza Alas¸alvar,Mustafa Cam 한국식품과학회 2019 Food Science and Biotechnology Vol.28 No.3

The aim of this study was to produce ready todrink (RTD) iced teas from sage and linden. For this purpose,phenolics of sage and linden were extracted bypressurized hot water extraction (PHWE) and then theextracts obtained were spray dried by the addition ofmaltodextrin. The powders produced by spray drying wereprocessed into RTD sage and linden iced teas by addingsucrose and citric acid. The optimum conditions of PHWEof sage and linden were at 160 C and for 10 min and5 min, respectively. The solubility and microencapsulationefficiency of spray dried powders were found to be greaterthan 97%. In addition, total phenolic content and antioxidantactivity of RTD iced teas are parallel with those ofmicroencapsulated sage and linden powders after pasteurizationat 80 C for 5 min. The sensory analysis of RTDiced teas showed that products were well-accepted by thepanelists.

Majapahit, Sali Alas,Hwang, Mintae The Korea Institute of Information and Commucation 2021 Journal of information and communication convergen Vol.19 No.4

An early warning system was developed to help identify stock status as early as possible. For performance to improve, there needs to be a feature to predict the amount of stock that must be provided and a feature to estimate when to buy goods. This research was conducted to improve the inventory early warning system and optimize the Reminder Block's performance in minimum stock settings. The models used in this study are the single exponential smoothing (SES) method for prediction and the economic order quantity (EOQ) model for determining the quantity. The research was conducted by analyzing the Reminder Block in the early warning system, identifying data needs, and implementing the SES and EOQ mathematical models into the Reminder Block. This research proposes a new Reminder Block that has been added to the SES and EOQ models. It is hoped that this study will help in obtaining accurate information about the time and quantity of repurchases for efficient inventory management.

Silvia Waleska Bu,César Alas-Pineda,David Aguilar-Andino,Dalton Argean Norwood,Kristhel Gaitán-Zambrano,Mario Pinto-Romero 대한산부인과학회 2023 Obstetrics & Gynecology Science Vol.66 No.2

ObjectiveTo compare the effect of intraumbilical vein oxytocin injection with standard management in reducing blood loss during the third and fourth stages of labor. Acute complications threaten the mother’s life during the third and fourth stages of labor. The most common complication is postpartum hemorrhage, which remains a leading cause of maternal mortality, particularly in developing countries. MethodsA randomized controlled trial was conducted in the Gynecology and Obstetrics Department of Leonardo Mart?nez Valenzuela Hospital from January to June 2021. A probabilistic sample was used: 332 pregnant patients were enrolled in the study and randomized into the case (166 patients) and control (166 patients) groups. The volume of blood lost was compared between the groups. ResultsThe median estimated blood loss was 120 mL (interquartile range [IQR], 80-218.75 mL). There was a statistically significant difference between the groups, showing less estimated blood loss in the international unit group with a median of 80 mL (IQR, 60-100 mL) (P<0.001), and 200 mL (IQR, 143.75-300 mL) in the intramuscular (IM) group, highlighting that 66.8% of the IM group had an estimated blood loss >251 mL. ConclusionAny reduction in bleeding during labor is clinically relevant because it improves patient prognosis. The use of intraumbilical oxytocin injection with active management of the third stage of labor significantly reduced postpartum blood loss and the duration of the third stage compared with the IM group.

Aerosol particle mixing state, refractory particle number size distributions and emission factors in a polluted urban environment: Case study of Metro Manila, Philippines

Kecorius, S.,Madueno, L.,Vallar, E.,Alas, H.,Betito, G.,Birmili, W.,Cambaliza, M.O.,Catipay, G.,Gonzaga-Cayetano, M.,Galvez, M.C.,Lorenzo, G.,Muller, T.,Simpas, J.B.,Tamayo, E.G.,Wiedensohler, A. Pergamon Press ; Elsevier [distribution] 2017 Atmospheric environment Vol.170 No.-

Ultrafine soot particles (black carbon, BC) in urban environments are related to adverse respiratory and cardiovascular effects, increased cases of asthma and premature deaths. These problems are especially pronounced in developing megacities in South-East Asia, Latin America, and Africa, where unsustainable urbanization ant outdated environmental protection legislation resulted in severe degradation of urban air quality in terms of black carbon emission. Since ultrafine soot particles do often not lead to enhanced PM<SUB>10</SUB> and PM<SUB>2.5</SUB> mass concentration, the risks related to ultrafine particle pollution may therefore be significantly underestimated compared to the contribution of secondary aerosol constituents. To increase the awareness of the potential toxicological relevant problems of ultrafine black carbon particles, we conducted a case study in Metro Manila, the capital of the Philippines. Here, we present a part of the results from a detailed field campaign, called Manila Aerosol Characterization Experiment (MACE, 2015). Measurements took place from May to June 2015 with the focus on the state of mixing of aerosol particles. The results were alarming, showing the abundance of externally mixed refractory particles (soot proxy) at street site with a maximum daily number concentration of approximately 15000 #/cm<SUP>3</SUP>. That is up to 10 times higher than in cities of Western countries. We also found that the soot particle mass contributed from 55 to 75% of total street site PM<SUB>2.5</SUB>. The retrieved refractory particle number size distribution appeared to be a superposition of 2 ultrafine modes at 20 and 80 nm with a corresponding contribution to the total refractory particle number of 45 and 55%, respectively. The particles in the 20 nm mode were most likely ash from metallic additives in lubricating oil, tiny carbonaceous particles and/or nucleated and oxidized organic polymers, while bigger ones (80 nm) were soot agglomerates. To the best of the authors' knowledge, no other studies reported such high number concentration of ultrafine refractory particles under ambient conditions. Inverse modeling of emission factors of refractory particle number size distributions revealed that diesel-fed public utility Jeepneys, commonly used for public transportation, are responsible for 94% of total roadside emitted refractory particle mass. The observed results showed that the majority of urban pollution in Metro Manila is dominated by carbonaceous aerosol. This suggests that PM<SUB>10</SUB> or PM<SUB>2.5</SUB> metrics do not fully describe possible health related effects in this kind of urban environments. Extremely high concentrations of ultrafine particles have been and will continue to induce adverse health related effects, because of their potential toxicity. We imply that in megacities, where the major fraction of particulates originates from the transport sector, PM<SUB>10</SUB> or PM<SUB>2.5</SUB> mass concentration should be complemented by legislative measurements of equivalent black carbon mass concentration.

Effect of urea concentration on microbial Ca precipitation

Mustafa Isık,Levent Altas,Samet Ozcan,Ismail Simsek,Osman Nuri Agdag,Ali Alas 한국공업화학회 2012 Journal of Industrial and Engineering Chemistry Vol.18 No.6

High calcium concentrations are problematic, because they lead to clogging of pipelines, boilers and heat exchangers through scaling, or malfunctioning of aerobic and anaerobic reactors. Urea hydrolysis provides simultaneously a pH and CO2 increase, both of which are responsible of CaCO3 production. This study was carried out to determine urea concentrations between 5 and 20 mM on ureolytic mixed culture treating synthetic wastewater. The optimum urea concentration was found as 15 mM for effective calcium removal. This work showed the feasibility of urea-based microbial carbonate precipitation as an alternative Ca2+ removal technology.

The Role of Philippine Local Traders in the Domestic and International Market for Quality Seaweeds

Earl Joanne Santos-Ramirez,Paul Joseph B. Ramirez,Orelie B. Delas Alas,Carlos L. Magnaye 한국무역학회 2019 한국무역학회 국제학술대회 Vol.2019 No.08

This paper highlights the important role of traders in the seaweeds value chain in the Philippines. Using rapid appraisal and value chain approaches, the study analyzed the contribution of traders in terms of their value additions and essential activities necessary to bring quality raw dried seaweeds and semi-refined carrageenan to final markets. In the two cases studied, results showed that, on a per kilogram basis, the barangay and large/provincial traders received the least share among value chain players but are compensated commensurately. For both established and emerging seaweeds value chain areas examined, the role of the traders in linking up players and matching the supply and demand by effectively consolidating to meet volume and quality requirements and ensuring competitive prices was found indispensable.

Opportunities for Improving Value in Global Seaweed Products Trade: A Value Chain Analysis for Seaweeds in the Philippines

Paul Joseph B. Ramirez,Earl Joanne Santos-Ramirez,Orelie B. Delas Alas,Carlos L. Magnaye 한국무역학회 2019 한국무역학회 국제학술대회 Vol.2019 No.08

The paper focused on identifying potential upgrading solutions along the seaweeds value chain in the Philippines. Using rapid appraisal and value chain approaches, the study revealed that the seaweeds industry is performing relatively well but there is still room for improvement. Based on two sets of value chain cases analyzed, the industry can capture greater value and revenues by transforming raw dried seaweeds to carrageenan rather than selling the former outright to other countries. The estimated value added in the two cases displayed that the processors in both scenarios receive much better gains, triple at the least of the raw dried seaweed exporters. This can also improve utilization of existing seaweeds processing plants and support the employment of local workers. Apart from the fact that the country has a competitive advantage in producing quality carrageenan, it will save the carrageenan plants from sourcing out their raw dried seaweeds inputs from its competitor countries that would also have impact on the bottom lines of the industry.

Objective: To prioritize the cervical parameter targets for alignment. Methods: Included: cervical deformity (CD) patients (C2–7 Cobb angle>10°, cervical lordosis>10°, cervical sagittal vertical axis [cSVA]>4 cm, or chin-brow vertical angle>25°) with full baseline (BL) and 1-year (1Y) radiographic parameters and Neck Disability Index (NDI) scores; patients with cervical [C] or cervicothoracic [CT] Primary Driver Ames type. Patients with BL Ames classified as low CD for both parameters of cSVA (<4 cm) and T1 slope minus cervical lordosis (TS–CL) (<15°) were excluded. Patients assessed: meeting minimum clinically important differences (MCID) for NDI (<-15 ΔNDI). Ratios of correction were found for regional parameters categorized by primary Ames driver (C or CT). Decision tree analysis assessed cutoffs for differences associated with meeting NDI MCID at 1Y. Results: Seventy-seven CD patients (mean age, 62.1 years; 64% female; body mass index, 28.8 kg/m2). Forty-one point six percent of patients met MCID for NDI. A backwards linear regression model including radiographic differences as predictors from BL to 1Y for meeting MCID for NDI demonstrated an R2 of 0.820 (p=0.032) included TS–CL, cSVA, McGregor’s slope (MGS), C2 sacral slope, C2–T3 angle, C2–T3 SVA, cervical lordosis. By primary Ames driver, 67.5% of patients were C, and 32.5% CT. Ratios of change in predictors for MCID NDI patients for C and CT were not significant between the 2 groups (p> 0.050). Decision tree analysis determined cutoffs for radiographic change, prioritizing in the following order: ≥42.5° C2–T3 angle, >35.4° cervical lordosis, <-31.76° C2 slope, <-11.57-mm cSVA, <-2.16° MGS, >-30.8-mm C2–T3 SVA, and ≤-33.6° TS–CL. Conclusion: Certain ratios of correction of cervical parameters contribute to improving neck disability. Prioritizing these radiographic alignment parameters may help optimize patient-reported outcomes for patients undergoing CD surgery.

Removal of Esophageal Variceal Bands to Salvage Complete Esophageal Obstruction

Ala’ A Abdel Jalil,Ghassan Hammoud,Jamal A Ibdah,Sami Samiullah 대한소화기내시경학회 2018 Clinical Endoscopy Vol.51 No.5

Esophageal varices develop in almost half of the patients with cirrhosis, and variceal hemorrhage constitutes an ominous sign with anincreased risk of mortality. Variceal banding is considered an effective and mostly safe measure for primary and secondary prophylaxis. Although adverse events related to banding including dysphagia, stricture formation, bleeding, and ligation-induced ulcers have beendescribed, complete esophageal obstruction is rare, with only 10 reported cases in the literature. Among those cases, 6 were managedconservatively; 1 patient had esophageal intraluminal dissection from an attempt to remove the bands using biopsy forceps butultimately recovered with conservative management. Three patients developed strictures following removal of the bands, requiringrepeated sessions of dilation therapy. We report on a patient who developed absolute dysphagia and complete esophageal obstructionafter variceal banding. We successfully used the endoloop cutter hook to release the bands intact and restore luminal integrity.
