Semi-Automatic Indonesian WordNet Establishment : From Synset Extraction to Visual Editor
Gunawan,I Ketut Eddy Purnama,Mochamad Hariadi 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.8
In this study, we have developed an Indonesian WordNet through four main phases: synonym set extraction (synset) as the smallest entity of lexical database from a natural language, semantic relation establishment between synsets (hypernym-hyponym and holonym-meronym), gloss extraction for synset collection, and the visual editor creation. The Semi-automatic term refers to the three initial phases which are automatically done using a number of machine learning approaches, while using visual editor to collaboratively complement the results collected from the previous phases. A number of raw data used on synset acquisition, semantic relations and glosses come from Kamus Besar Bahasa Indonesia (Great Dictionary of the Indonesian Language, abbreviated as KBBI) and Tesaurus Bahasa Indonesia (Indonesian Language Thesaurus), large collection of web pages from search engines, Wikipedia, and even Princeton WordNet for mapping purpose. This study shows that the proposed system successfully achieve 37,485 synsets, 24,256 hypernym-hyponym relations, 11,044 holonym-meronym relations and 6,520 gloss synsets. Similar approach is believed to accelerate lexical database development like WordNet for other languages.

Purpose – The purpose of was paper is to do a conceptual analysis of the determination of local superior commodities using the location quotient technique and an analysis of the contribution of superior products to the regional economy. The results of determining superior commodities are used to determine regional product specialization and its contribution to the regional economy. Local superior commodities are dynamic and selected based on the potential to increase regional income. Research design, data, and methodology - This study used location quotient techniques and regional economic analysis with annual data rocks, production data in the agriculture, plantation, fishery and forestry sectors. Local superior commodities are calculated to contribute to regional economists. Result – The findings obtained showed the location quotient technique can determine local superior commodities and local superior commodities contributed positively to the regional economy. The test results were carried out in Jember Regency, East Java Province, Indonesia. Conclusion – The ass well main commodities of Jember Regency are tobacco. Tobacco commodities contribute positively to the regional economy, they were not significantly due to affected by the low of commodity prices in harvest. The low prices indicate the strength of the weak bargaining position of farmers towards the market.
Guillain-Barre Syndrome Following SARS-CoV-2 Vaccination: A Case Report
Pricilla Yani Gunawan(Pricilla Yani Gunawan ),Pamela Tiffani(Pamela Tiffani ),Lilie Lalisang(Lilie Lalisang ) 대한정신약물학회 2022 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.20 No.4
After more than a year of Coronavirus disease 2019 pandemic, in 2021 Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) vaccination have been made possible and vaccine was distributed globally. Since then, there have been reports of symptoms following SARS-CoV-2 vaccination, including neurological symptoms of ascending paralysis known as Guillain-Barre syndrome. In this report, we describe the first case of Guillain-Barre syndrome following vaccination in Indonesia. Symptoms of ascending paralysis were of late onset after the first dose, however, were full blown after receiving the second dose followed by left-sided facial paralysis.

Background: Efficacy of childhood cancer treatment in low-income countries may be impacted by parents' and health-care providers' perspectives on chemotherapy-related side-effects. This study explores prevalence and severity of side-effects in childhood cancer, and compares health beliefs about side-effects between parents and health-care providers, and between nurses and doctors in Indonesia. Materials and Methods: Semi-structured questionnaires were filled in by 40 parents and 207 health-care providers in an academic hospital. Results: Parents exporessed a desire to receive more information about side-effects (98%) and worried about this aspect of treatment (90%), although side-effects were less severe than expected (66%). The most frequent was behavior alteration (98%) and the most severe was hair loss. Only 26% of parents consulted doctors about side-effects. More parents, compared to health-care providers, believed that medicines work better when side-effects are more severe (p<0.001), and accepted severe side-effects (p=0.021). More health-care providers, compared to parents, believed that chemotherapy can be stopped or the dosage altered when there are side-effects (p=0.011). More nurses, compared to doctors, stated that side-effects were unbearable (p=0.004) and made them doubt efficacy of treatment (p<0.001). Conclusions: Behavior alteration is the most frequent and hair loss the most severe side-effect. Apparent discrepancies in health beliefs about side-effects exist between parents and health-care providers. A sustainable parental education program about side-effects is recommended. Health-care providers need to update and improve their knowledge and communication skills in order to give appropriate information. Suchmeasures may improve outcome of childhood cancer treatment in low-income countries, where adherence to therapy is a major issue.

The present study evaluates the influences of PWHT on FCG behavior and tensile properties of TIG butt welded Al 6013-T4 sheets. Crack propagation tests were carried out on compact tension (CT) specimens. The T82 heat treatment was varied in three artificial aging times (soaking) of 6, 18 and 24 hours. The results of T82 heat treatment with artificial aging variations were tested for their fatigue crack growth rates at the main metal zone, the heat-affected zone (HAZ), and the welded metal zone. It has been observed that the various agings in heat treatment T82 are sensitive to the mechanical properties (fatigue crack growth rate test, tensile test). The results show that PWHT-T82 for 18 hours aging is the highest fatigue resistance, while the aging 18 hours provided the highest tensile test result.

Abstract. In micro-EDM (electrical discharge machining), improper removal of debris causes short-circuiting between a tool electrode and a workpiece and in turn, prevents continuous machining process. Therefore, a remarkably longer period of time is required to fabricate a through hole than that would be required when no short-circuiting took place. In order to solve this problem, the dielectric fluid is immersed with graphite nano powders to reduce machining time and improve surface quality due to the less frequent of arcing between the tool electrode and the workpiece. However, excess powders become debris and subsequently deteriorate the efficiency of machining. To fully exploit the effects of the suspended powders, we introduced vibration of the workpiece in order to remove the debris in the small gap between the workpiece and electrode efficiently. The experimental results showed that combination of these techniques improved machining stability, assured continuous machining processes, and significant reduction of the machining time. Reduction of the machining time and the surface roughness of the workpiece after machining were investigated with respect to the powder concentrations when the workpiece was vibrated at 1000 Hz.
THREE GEOMETRIC CONSTANTS FOR MORREY SPACES
Gunawan, Hendra,Kikianty, Eder,Sawano, Yoshihiro,Schwanke, Christopher Korean Mathematical Society 2019 대한수학회보 Vol.56 No.6
In this paper we calculate three geometric constants, namely the von Neumann-Jordan constant, the James constant, and the Dunkl-Williams constant, for Morrey spaces and discrete Morrey spaces. These constants measure uniformly nonsquareness of the associated spaces. We obtain that the three constants are the same as those for $L^1$ and $L^{\infty}$ spaces.
Fractional Integrals and Generalized Olsen Inequalities
Gunawan, Hendra,Eridani, Eridani Department of Mathematics 2009 Kyungpook mathematical journal Vol.49 No.1
Let $T_{\rho}$ be the generalized fractional integral operator associated to a function ${\rho}:(0,{\infty}){\rightarrow}(0,{\infty})$, as defined in [16]. For a function W on $\mathbb{R}^n$, we shall be interested in the boundedness of the multiplication operator $f{\mapsto}W{\cdot}T_{\rho}f$ on generalized Morrey spaces. Under some assumptions on ${\rho}$, we obtain an inequality for $W{\cdot}T_{\rho}$, which can be viewed as an extension of Olsen's and Kurata-Nishigaki-Sugano's results.
