Published: December 2020

RESUMO Objetivo: Verificar associação entre sobrepeso, obesidade e pressão arterial elevada em escolares brasileiros com idade entre 6 e 10 anos incompletos. Método: Estudo seccional realizado no município de Macaé, RJ, em que foi coletado massa corporal, estatura e pressão arterial. O índice de massa corporal foi calculado pelo software Anthro Plus e classificado conforme SISVAN. Pressão arterial sistólica/diastólica elevada quando ≥ percentil 90 por idade, sexo e percentil da estatura/idade (7ª Diretriz Brasileira de Hipertensão). A análise foi por regressão logística com intervalo de confiança 95%, software SPSS. Resultados: Foram avaliadas 911 crianças e, após estratificação por estado nutricional, as com magreza foram excluídas. Entre as 888 crianças restantes, a prevalência de sobrepeso foi 17,7% e obesidade 16,2%. A prevalência de pressão arterial elevada foi 34%, não diferindo entre sexo (p=0,57). Sobrepeso foi significativamente associado à pressão elevada no grupo de 8-9 anos (OR 1,99; p=0,004), enquanto a obesidade associou-se em ambos os grupos (6-7 anos OR 2,50; p=0,004 e 8-9 anos OR 4,21 p=0,001). Conclusão: Os resultados demonstraram que sobrepeso e obesidade aumentaram expressivamente a chance de pressão arterial elevada entre crianças de 6 a 10 anos incompletos.

Published: December 2020

Aim: To determine the reference values of strong ion difference (SID), effective SID (SIDe), unmeasured anions (UMA), tissue acids (TA), lactate and Chloride-Sodium (Cl-Na) ratio of umbilical cord blood, and to evaluate the impact of delivery mode on these parameters.
Methods: This prospective study was performed on healthy term newborn infants that had normal progress throughout the first and second stages of labor during normal spontaneous delivery (NSD) and cesarean section (C/S). Immediately after birth, 1ml and 2 ml of umbilical venous cord blood samples were obtained for blood gas analysis and blood chemistry respectively. The Cl-Na ratio, anion gap (AG), albumin corrected AG (AGCorr), SID, SIDe, UMA and TA were calculated in NSD and C/S groups..
Results: A total of 181 healthy newborn infants were included the study. Fifty-one infants were delivered by NSD and 130 infants by C/S. The pH and PCO2 values were similar in both groups. The mode of delivery had a significant impact on the umbilical cord AG, AGCorr, SID, lactate, UMA, and TA levels. All these values were significantly higher in NSD than C/S group.
Conclusion: Umbilical cord blood gas analysis is a common practice to evaluate fetal status at delivery. The calculation of blood gas parameters in perinatal problems according to Stewart’s method may lead further understanding how perinatal conditions of the mother influence the fetus and newborn infant.
Analyzing the impact of external debt on industrialization : the African franc zone case
Authors: FOGANG Daniel Deric MBOUNANG , TCHITCHOUA Jean
Published: December 2020

This paper uses data from 10 countries of the African franc zone from 1996 to 2017, to gauge the effect of external debt on industrialization in the presence of non-linearity. Our analyzes are done based on two aspects. Firstly, using a Panel Smooth Transition Regression (PSTR), our results show that there is a non-linear relationship between external debt and industrialization in the African franc zone, which depends on the level of the external debt stock, the threshold is $58.91 \%$ of GDP. While before this threshold, external debt has no direct effect on industrialization, after this threshold it is harmful to it. Secondly, an analysis in two periods (1996-2006 and 2007-2017) by the GLS and SUR methods shows that before 2006, the external debt was an asset for industrialization but after, it gave way to domestic credit. Thus, the external debt has become obsolete after reaching the completion point of the HIPC initiative, and would be a danger for the industrialization of the franc zone in the event of excess.

Szulejmání tábornok halálára – 2. rész
Authors: Katona Magda
Published: December 2020

Az Iráni Iszlám Köztársaság Qudsz erőinek parancsnoka, Qászem Szulejmání vezérőrnagy 2020. január 3-án amerikai drón általi likvidálása mérföldkő az amerikai–iráni kapcsolatok terén, és fordulatot jelent a nemzetközi politika színpadán. Bár a nemzetközi kapcsolatok nem szokásos eleme, de jusztifikálható.Az iráni nemzetbiztonsági stratégia az Irakkal vívott háború (1980–1988) tanulságainak levonását követően alakult ki, melyben az Iráni Iszlám Forradalmi Gárda és azon belül a Qudsz (Jeruzsálem) erők különleges szerephez jutottak. Utóbbi hírneve Szulejmání tábornok tevékenységével jellemezhetõ. A meggyilkolt tábornok különleges stratégiát dolgozott ki, amelynek lényege katonai és politikai erő együttes alkalmazása volt. Előbbit az aszimmetrikus és hibrid hadviselés, valamint helyettesítő erők és helyettesítő helyi háborúk globális hálózata jellemezte. Az Iráni Iszlám Köztársaság megalakulása óta szervez és kivitelez terrorcselekményeket és támogat terrorszervezeteket globális viszonylatban. Mindaddig, amíg ezek következmények nélküliek voltak, tehette. Most szembesül tetteinek következményeivel. Az éles retorika ellenére mindezidáig a tervezett nagy megtorlás elmaradt, sőt, globális mértékben számottevően csökkent a terrorcselekmények száma. Ami a nemzetközi politikai következményeket illeti, a mélyülő krízis Iránnal kiélezheti a globális és regionális hatalmi vetélkedést. Az Iszlám Állam újra előretörhet. A krízis eszkalációjának vagy de-eszkalációjának a kulcsa a Perzsa-öböl térsége.
Az ANZUS mint kollektív védelmi szervezet
Authors: Szakács Mirjam
Published: December 2020

A második világháború utáni bizonytalan nemzetközi környezetben az ANZUS-szerződés három évtizeden keresztül biztosította a kollektív védelem privilégiumait Új-Zéland számára. Azonban Új-Zéland nukleáris politikája 1984 és 1987 között az amerikaiakat a szerződéstől való elállásra késztette, így Új-Zéland de facto kikerült az amerikai kollekív védelmi garanciák biztosítása alól. A tanulmány célja, hogy – magyar nyelven elõször – átfogó képet adjon az ANZUS-ról, mint kollektív védelmi szervezetről, Új-Zéland globális és regionális szerepéről, a változó külpolitikai magatartásáról és a döntéseit meghatározó belpolitikai faktorokról. A tanulmány elemzi, hogy vajon milyen okai voltak annak, hogy a szövetség, amely eleinte közös biztonság- és védelempolitikai érdekek mentén szerveződött, idővel a trilaterális kollektív védelmi szervezetből bilaterális szövetséggé alakult át?
A haderő vezetésének kérdései az első világháborús osztrák–magyar tábornoki kar példáján
Authors: Balla Tibor
Published: December 2020

Az átlagos vezetői és hadvezéri képességekkel rendelkező osztrák–magyar tábornokok tevékenységének hatékonyságát számos tényező korlátozta az első világháború folyamán. A haderőt a háború idején irányító két vezérkari főnök (Franz Conrad von Hötzendorf tábornagy és Arthur Arz von Straussenburg vezérezredes) is számos vezetési hibát követett el. A vezető beosztásokra alkalmatlan vagy hadvezérként kudarcot vallott tábornokok túlnyomó többségét még 1914-ben leváltották. A mindössze 25 fõnyi veszteséget szenvedett tábornoki kar összességében elfogadható vezetői teljesítményt mutatott fel, a háború végső kimenetelét azonban érdemben nem tudta befolyásolni.

Remaining useful life prediction of rolling bearings based on the three-parameter Weibull distribution proportional hazards model
Authors: Wang Ye , Chen Zhixiong , Zhang Yang , Li Xin , Li Zhixiong
Published: December 2020

In order to accurately predict the remaining useful life (RUL) of rolling bearings, a novel method based on the threeparameter Weibull distribution proportional hazards model (WPHM) is proposed in this paper. In this new method, degradation features of the bearing vibration signals
were calculated in the time, frequency and time-frequency domains and treated as the input covariates of the predictive WPHM. Essential knowledge of the bearing degradation dynamics was learnt from the input features to build an effective three-parameter WPHM for bearing RUL prediction. Experimental
data acquired from the run-to-failure bearing tests of the intelligent maintenance system (IMS) was used to evaluate the proposed method. The analysis results demonstrate that the proposed model is able to produce accurate RUL prediction for the tested bearings and outperforms the popular
two-parameter WPHM.

Authors:   Polytechnic Institute of Leiria, Amorim Daniela
Published: December 2020

The festivals have had a very positive impact on tourism development, and on the promotion of destinations, they are positioned as important attractive elements that boost tourism in the several regions, as well as its economic and cultural development. This study aimed to analyse the motivation, quality, satisfaction and loyalty of two performing arts festivals participants (Andanças, Portugal and La Sierra, Spain). It followed a quantitative methodology, and questionnaires were applied to the participants of the events under analysis. The results of the test-t indicate that La Sierra festival participants (n=235), compared to Andanças festival participants (n=297), perceive the festival as having more quality (catering, hotel, information and transport), and are more faithful to the festival (even if prices increase). The results obtained contribute to a better understanding of the needs and perceptions of participants who practice festival tourism, particularly in performing arts festivals, supporting the manager's strategies in organising this type of event.

Published: December 2020

Background and Purpose: Rhinocladiella mackenziei is a neurotropic fungus, which can cause devastating intracerebral infections with up to 100% fatality rate. It is difficult to isolate this fungus in laboratory as it grows slowly and requires diagnostic skills.
Case report: A 42-year-old Pakistani man presented with headache, facial numbness, progressive upper limb weakness, and dysarthria. Magnetic resonance imaging of thebrain showed a space-occupying lesion in the basal ganglia region. The patient underwent supratentorial craniotomy for biopsy and excision. Histopathology of the specimen revealed granulomatous inflammation with abscess formation. Periodic acidSchiff special stains highlighted the presence of numerous septate fungal hyphae. The results revealed the growth of dematiaceous fungi, which were morphologically classified as R. mackenziei. The patient is currently stable and is being on amphotericin and posaconazole, along with neurorehabilitation therapy.
Conclusion: Rhinocladiella mackenziei brain abscess is a devastating infection with significant mortality. This condition should be suspected in patients with brain abscessfrom high endemic areas

Published: December 2020

Background and Purpose: Herein, we describe a rare case of fatal cerebral phaeohyphomycosis by Cladophialophora bantiana in an immunocompetent individual without any underlying risk factors.Case report: A 55-year-old female presented with a short history of fever for 1 month, as well as headache, sudden onset of right-sided upper and lower limb weakness, and loss of speech for 10 days. Contrast-enhanced magnetic resonance imaging scan revealed large, peripherally enhancing, well-defined, cystic, space-occupying, axial lesion in the left parietal lobe with a mass effect. The patient was subjected to craniotomy, and the drained pus revealed pigmented septate hyphae in potassium hydroxide mount examination, which was identified as Cladophialophora bantiana. The patient was started on amphotericin B and voriconazole. However, she developed acute respiratory infection leading to multi-organ failure and death on day 27 post-operation.
Conclusion: In the absence of comparative trials owing to the rarity of the disease, the radical resection of lesion, drainage of pus, and prolonged targeted antifungal therapy with close postoperative radiological surveillance are the therapeutic measures of choice for patients with brain abscess caused by phaeoid fungi.

Authors: AKYOL Mehmet
Published: December 2020

Energy plays an important role in maintaining vital activities. Like other sectors, with the developing technology, energy is used in agricultural activities. The rapid and uncontrolled increase in energy consumption in agricultural production, has sometimes led to a decrease in the efficiency of the energy use. Inefficient use of energy, which is a production input, leads to an increase in production costs. The increase in production costs leads to a relative decrease in output and such negativities exposing producers to loss of income.. Within the framework of the analysis, 10 countries who are called as transition economies and EU member as well were included in the study. Dynamic panel data method was used in the study which analyzed the period between 2009-2017. As a result of the analysis, it was observed that agricultural energy consumption had a positive effect on agricultural value added.

Bu çalışmada amaç; Bitcoin, döviz kuru, Borsa İstanbul Endeksi ve faiz değişkenleri arasındaki ilişkileri Türkiye için 2013:11-2019:10 dönemi haftalık verileri kullanarak incelemektir. Çalışmada VAR modeli kurularak değişkenler arasındaki uzun dönem ve nedensellik ilişkileri araştırılmış, etki-tepki grafikleri ve varyans ayrışım tablosuyla analiz sonuçlandırılmıştır. Çalışma sonucunda Bitcoin ile diğer değişkenler arasında uzun dönemde herhangi bir eşbütünleşme ilişkisi ve nedensellik ilişkisi tespit edilememiş, ancak diğer değişkenlerin kendi aralarında nedensellik ilişkileri saptanmıştır. Etki-tepki grafiklerine göre Bitcoin’e verilen bir şoka döviz kuru üç haftalık negatif tepki göstermiş diğer haftalarda verilen tepki anlamsız olmuştur. Türkiye’de kripto paralar üzerinde belirli bir farkındalığın olduğu ancak bu farkındalığın uzun vadeli yatırım boyutunda ve makro değişkenleri etkileyebilecek güçte olmadığı görülmektedir. Türkiye’de yeni sayılabilecek olan bu teknolojinin yaygınlaşabilmesi için belirli bir zamana ihtiyaç vardır.
Innovative Early Sequenced Multidrug Therapy for Sars-Cov-2 (Covid-19) Infection to Reduce Hospitalization and Death
Authors: McCullough Peter
Published: December 2020

The SARS-CoV-2 virus spreading across the United States has led to surges of COVID-19 hospitalizations and death.  It is clear that randomized trials of single drugs will fail to resolve the crisis due to the complex and multifaceted nature of COVID-19 illness including viral mediated organ damage, cytokine storm, and thrombosis.  Patients endure long untreated periods before succumbing to hospitalization and delayed treatment.  Thus, early innovative, sequenced multidrug regimens have the best chance of success and are prudent as the next direction in randomized trials and advanced practice.  Early management includes:  1) environmental efforts to reduce reinoculation and maintain isolation in the home, 2) combination anti-infective therapy, 3) corticosteroids, 4) antiplatelet agents/antithrombotics, 5) supportive care including supplemental oxygen, monitoring, and telemedicine.  Randomized trials of novel oral therapies have not delivered tools of physicians to combat the pandemic in practice.  Thus, an immediate pivot from single drug to innovative sequenced multidrug regimens is required as the only strategy to deal with current acute cases of COVID-19 with the aim of avoiding hospitalization and death.

Long-Term Strength Estimation of Zirconia Ceramics
Authors: Aliev A.A.
Published: December 2020

A standard experimental assessment of the service life of high-temperature zirconia ceramics (GOST 4070–2014) requires the use of complicated heating and measuring equipment and hundreds of expensive specimens. This necessitates the development of calculation methods for evaluating long-term strength depending on the thermomechanical loading conditions without carrying out a full range of laboratory tests. The existing experimental estimation models of the primary and secondary creep regimes of ceramics consider the temperature range up to 1600°C, which is lower than zirconia limiting operating temperatures (2000°C and higher). Based on the Norton – Bailey law, long-term strength estimation of fully stabilized zirconia ceramics is carried out. Using previously known experimental data of other authors for ceramics made of fully stabilized zirconia (0.1Y2O3 + 0.9ZrO2), the creep constants values were calculated at high-temperature (1600–1800 °C) loading levels ≤5 MPa. A power-law regression equation with a high degree of correlation that evaluates the creep of the test material under loads up to 20 MPa and temperatures up to 2100 °C is proposed.
Approximate calculations of the eigenvalues of a rotating fluid flowing from an arbitrary axisymmetric capacity
Authors: Orlov V.V.
Published: December 2020

The paper addresses the problem of proper motions of a rotating fluid that partially fills an axisymmetric vessel in the presence of an outflow through a rigid bottom. The problem is solved in a quasi-stationary setting within the framework of an ideal fluid model, with account for hydraulic losses during fluid flow through the bottom of the vessel. Numerical research was carried out using the finite element method. The study investigates the spectrum of eigenvalues and reveals the characteristics of the wave motions of the fluid. Numerical calculations confirm the possible appearance of wave motions on the drain surface, i.e. drain waves caused by the presence of fluid outflow through the bottom of the vessel. The paper presents the results of calculating the wavenumbers and the complex attenuation coefficient. Findings of the research can be used in practical calculations of dynamic modes at the design stage of promising space-rocket vehicles.
The Reynolds number and flaperon deflection influence taken into account when optimizing the wing airfoil of an unmanned aerial vehicle
Authors: Kochurova N.I. , Parkhaev Ye.S. , Semenchikov N.V.
Published: December 2020

The paper considers the solutions to the multicriteria problem of optimizing the wing airfoil of a miniature unmanned aerial vehicle (MUAV) under various constraints. The study introduces the statement of the problem of multicriteria optimization of the airfoil shape, following the condition of MUAV horizontal flight, with an additional condition associated with a change in the flight Reynolds number of the MUAV wing. This statement of the problem allows us to optimize the airfoil, taking into account the load on the wing of the designed vehicle. The wing airfoil was optimized in a wide range of lift coefficients of Cya and Reynolds numbers. The study shows that taking into account the Reynolds number makes it possible to improve the quality of the result obtained during optimization, and introduces a technique for multicriteria optimization of the wing airfoil with sealed mechanization, i.e. with flaperon. Findings of research show that for equal values of the relative thickness, the mechanized airfoil obtained as a result of optimization has a lower center line camber (by 1.5%) than the optimized airfoil without mechanization, due to which a gain in the drag coefficient is achieved at close to zero values of the lift coefficient. The study shows how profitable the use of a wing airfoil with a flaperon on MUAV wings can be, in contrast to an airfoil without mechanization.

Airplane director control algorithm in landing mode
Authors: Lukyanov V.V. , Alexeev A.N. , Zemlyany E.S. , Chekanov K.A.
Published: December 2020

The director control mode is an integral part of all modern aircraft, i.e. civil, military, transport and even unmanned aerial vehicles. The paper describes the experience of developing, implementing and perfecting the directorial control algorithm in the landing mode as applied to small aircraft DA-42-T and L-410 during flight tests. As the basic algorithm, the algorithm “Deviation allowance” is used. The satellite navigation system, i.e. GPS / GLONASS without differential correction, was selected as the main data source for the approach. This solution allows for semi-automatic landing at an unequipped airfield, but is inferior in accuracy to instrument landing, e.g. ILS, RSBN. According to the results of flight tests, we assessed the accuracy and found that the developed algorithm allows landing in accordance with the 1st category of ICAO.
Method for calculating the perturbed trajectoryof a two-impulse flight between the halo orbit in the vicinity of the L2 point of the Sun — Earth systemand the near-lunar orbit
Authors: Rui Zhou
Published: December 2020

The paper introduces a new method for solving the problem of calculating the perturbed trajectory of a two-impulse flight between a near-lunar orbit and a halo orbit in the vicinity of the L2 point of the Sun — Earth system. Unlike traditional numerical methods, this method has better convergence. Accelerations from the gravitational forces of the Earth, the Moon and the Sun as point masses and acceleration from the second zonal harmonic of the geopotential are taken into account at all sections of the trajectory. The calculation of the flight path is reduced to solving a two-point boundary value problem for a system of ordinary differential equations. The developed method is based on the parameter continuation method and does not require the choice of an initial approximation for solving the boundary value problem. The last section of the paper provides examples and results of the analysis based on this method.

Authors: LİMON İbrahim , AYDIN Bahri
Published: December 2020

This study aims to determine school principals’ views on autonomy in school administration. Phenomenological design was employed in the study. Data were collected through interviews and analyzed using descriptive analysis. The participants were 14 high school principals. They were employed by maximum diversity sampling method. Data was collected through a semi-structured interview form. Accroding to findings, all of the participants stated that a school principal should be autonomous in performance evaluation, budget management, deciding on expenditures. On the other hand, most of them stated that a school principal should be autonomous in selecting deputy principal and the staff, deciding workday calendar and daily timetable, coursebooks and syllabus, quota of the school and the number of the students for each classroom. Another finding of this study is that local governments and parents are the most important components that support an autonomous school principal. As for the advantages and disadvantages of principal autonomy it is stated that the educational quality and efficacy of school administration will increase and the student performance will improve; however, there may be subjective practices and pressures on school principal. Lastly, political power and centralized educational system are regarded as the barriers to principal autonomy.

Published: December 2020

Purpose: The prevalence of atopy has been investigated in different autoimmune diseases in various studies. But, the atopic status in primary Sjögren’s syndrome (pSS) patients has not been evaluated yet. We aimed to determine the relationship between pSS and atopy. Material and Method: Fifty consecutive adult patients with pSS and fifty age and sex-matched controls were prospectively recruited in this study pSS patients were evaluated with laboratory tests and disease activity score. All subjects underwent skin prick test to a standard panel of common aeroallergens. Results: Ten patients (10/50, 20%) in the pSS group and five patients (6/50, 12%) in the control group had positivity on skin prick tests with common inhalant allergens (p=0.267). No significant differences were found regarding the clinical characteristics between atopic and non-atopic pSS patients. Conclusions: Atopic status and allergen sensitization were evaluated in pSS patients. To our knowledge, this is the first study investigating the inhalen allergen spectrum in pSS patients. The prevalence of atopy is similar in patients with pSS to the controls. But atopy may be related to milder clinical manifestations of pSS.
Kalkaneal Epin Hastalarında Fiziksel Aktivite Düzeyinin Ayak Ağrısı ve Fonksiyonel Performans Üzerindeki Etkisi
Authors: Vergili Özge , Oktaş Birhan , Aktaş Fatma , Arıkan Halime , Deveci Hülya
Published: December 2020

AMAÇ: Kalkaneal epin, hastalara ciddi anlamda rahatsızlık vererek günlük yaşam aktivitelerini kısıtlar. Çalışmamızın amacı bu bireylerde fiziksel aktivite düzeyinin ağrı ve fonksiyonellik yanıtları üzerindeki etkisini araştırmaktı.
GEREÇ VE YÖNTEM: Çalışma kalkaneal epin tanısı konmuş 41 birey ile yapıldı. Bireylerin yaş, cinsiyet, boy, kilo, beden kütle indeksi (BKİ) ve topuk ağrılarına ilişkin niteliksel ve niceliksel özellikleri sorgulandı. Bireylerin fiziksel aktivite düzeylerini değerlendirmek için Uluslararası Fiziksel Aktivite Anketi (UFAA) kullanıldı. Ayak ağrısını değerlendirmek için algometre, fonksiyonel performanslarını belirlemek için 6 dakika yürüme testi ve topuk yükseltme testi kullanıldı.
BULGULAR: Bireylerin 8’i (% 19,5) düşük düzeyde aktivite, 26’sı (% 63,4) orta düzeyde aktivite ve 7’si (% 17,1) yüksek düzeyde aktiviteye sahipti. Fiziksel aktivite düzeylerine göre sınıflandırılan bireylerde ayak ağrısı ve fonksiyonel performans parametreleri açısından anlamlı bir fark görülmedi.
SONUÇ: Yüksek düzeyde fiziksel aktivitenin özellikle yüksek BKİ'li bireylerde topuk ağrısı/ plantar fasiit/ kalkaneal epin gelişimi için önemli bir risk faktörü olduğu bilinmektedir. Bununla birlikte, aktif bir yaşamın ve egzersiz alışkanlığının gerek sistemik endokrin yanıtlar vasıtası ile ve gerekse kas iskelet sistemi ve vücut kompozisyonu üzerindeki olumlu etkileri ile söz konusu şikayetlerin görülme sıklığını azaltabileceği unutulmamalıdır. Daha geniş katılımlı ve kanıt düzeyi yüksek ileri çalışmalara ihtiyaç vardır.

Referring to the provisions of Law Number 7 of 1992 and its amendments to Law Number 10 of 1998 concerning Banking, it is explained that a Bank is a business entity that collects funds from the public in the form of deposits and distributes them to the public in the form of credit and or other forms of to improve the standard of living of the wider community so that the banking industry greatly affects the overall stability of the economy because banking institutions are intermediary institutions that bridge people who do not need their funds (surplus) to be deposited in banking institutions as deposits and distributed by these institutions to people who need them in a productive form of distribution. The role of banking institutions is systemic; in other words, banking is an important part of the economic system which will cause a multiplier effect if it is not healthy or in this case, it becomes a failed bank. The main function of banking in macroeconomic policy infrastructure is indeed directed in the context of how to make money effectively and efficiently to increase economic value, which requires the role of regulation in the economic sector as a rule for the essence and existence of banking institutions in carrying out their operations. This study is normative legal research that uses several approaches namely: the statute approach, the case approach, the historical approach, and the conceptual approach carried out with juridical concepts of banks, failed banks, bank restructuring, macroprudential and microprudential. The objective of this study is to comprehensively explain the model and system for rescuing failed banks that meet the benefits principles.

Published: December 2020

Indonesia's strategic geographic position as a link between the Central and Middle East Asia regions with Australia in the movement of migration flow has made Indonesia a transit area that many immigrants pass through. What needs to be watched out for are illegal entrances (mouse path), both sea routes and land routes, considering that Indonesia is a large archipelagic country and existing crossings have not been optimally guarded. Looking at these conditions, the existence of a world organization in Indonesia that deals with refugees, namely the United Nations High Commissioner for Refugees (UNHCR), can provide some temporary or permanent solutions, with short or long processes and mechanisms, which must be passed by refugees. The existence of refugees in Indonesia should be managed by the flow of the process in which refugees will be placed in third countries. In the waiting process when they will be dispatched to a third country, the refugees occupy a shelter which is then under the supervision of RUDENIM (Immigration Detention Center). From the description above, the problem in this research is studying RUDENIM's supervisory function on additional tasks in the context of immigration control of refugees in the aspect of state sovereignty. The research method used in answering problems is using normative juridical research methods, by analyzing secondary data and legal materials related to statutory regulations, books, and scientific journals. This research also uses several approaches, namely statutory approach, conceptual approach, and case approach.
Enhancing seniors’ health-related quality of life
Authors: Shi Yuxi Vania , Komiak Sherrie Yi , Komiak Paul
Published: December 2020

Virtual healthcare information technologies (HIT) are being adopted during the Covid-19 pandemic. We propose that even after Covid-19, virtual HIT can still have great potentials to address the challenges brought by the aging population on healthcare systems. The key questions are (1) what kinds of virtual HIT will be useful for seniors and (2) how these HIT will affect senior citizens’ health-related quality of life (HRQL)? Centered on the concept of HRQL and grounded on task-technology fit (TTF) theory, this paper builds a framework of useful virtual HIT in the context of long-term care for seniors. The framework proposes senior citizens’ human characteristics (i.e. restricted mobility, deteriorated working memory and attention, and social isolation) will influence their health-related tasks (task adaptability, autonomy, and interdependence). A set of virtual healthcare systems can be designed to fit seniors’ tasks. These HIT will increase seniors’ HRQL through increased task-technology fit (i.e. quality of healthcare, timeliness of healthcare, and relationships with seniors). This framework can serve as a base for researchers and practitioners in their endeavor to design more suitable HIT for seniors.

Corporate social responsibility disclosure towards firm value
Authors: Fauziah Dien Ajeng , Sukoharsono Eko Ganis , Saraswati Erwin
Published: December 2020

This research aims to investigate and analyze the effect of corporate social responsibility disclosure on firm value, either directly or indirectly, by involving innovation as a mediator. This study uses secondary data on manufacturing companies listed on the Indonesia Stock Exchange for a period of four years from 2015 to 2018. The sample selection method uses the purposive sampling method with several criteria to produce 104 companies as the research sample so there are 416 observations. The analysis technique used is a simple and multiple linear regression analysis technique using the STATA 13 application as well as the Sobel Test for mediation tests. The results of this study provide empirical evidence that both in quality and quantity corporate social responsibility disclosure has an effect on increasing firm value. The results also show that corporate social responsibility disclosure cannot increase firm value through innovation due to a lack of research and development activity in most manufacturing companies because research and development activities require a long time and process as well as ineffective patent protection. Innovation has an insignificant effect on firm value due to the high cost of research and development can have an impact on large costs that reduce profits. However, innovation can be increased by corporate social responsibility disclosure, which means investing in corporate social responsibility disclosure can indirectly encourage the development of innovative product and process activities in the company. Innovation becomes a partial mediation variable so that innovation works partially in mediating between corporate social responsibility disclosure and firm value.

Authors: Anjani Herry Linda , Rosidi Rosidi , Achsin M.
Published: December 2020

The purpose of this research is to analyze the experience and understanding of village officials with respect to accountability in village fund financial management. Qualitative research methods with a phenomenological approach were used in this study through interviews with the village government in Tlogosari Village, Malang Regency, East Java Province, Indonesia. The results show that the accountability of village fund financial management is realized through the behavior of carrying out duties and responsibilities, greatest utilization of village discussions, and the overall activeness of village communities in supporting the village welfare. This understanding is considered to be in accordance with the Minister of Home Affairs Regulation No. 20 of 2018. Supporting parties of the implementation of village fund financial management, namely the village government, local government, and local inspectorates should increase their commitment and consistency in order to create accountable management of village funds. At the inspection stage, particularly, the regional inspectorate is required to make improvements in the inspection process to maximize targeted development in fulfillment of the village needs.
