Loneliness and Cyberloafing in the Time of COVID-19: A Psychological Perspective
Authors: Çolak Murat , Çetin Cemile
Published: September 2021

Background

The COVID-19 pandemic, which has affected the entire world, has driven countries into economic, social, and political uncertainty and has forced quite significant changes, especially in areas such as health, work, education, and social security. Social changes that are occurring as a result of the crisis include the restructuring of businesses and working styles and the shaping of work life along the new-normal axis. Many psychosocial risks such as conflict management, organisational relationships, communications problems, job satisfaction, stress, productivity, and performance are being redefined as the nature of jobs, job descriptions, employee competence, and ways of working are being recreated for a virtual environment. The importance of concepts related to work psychology such as loneliness, cyberloafing, digital mobbing, emotional resilience, psychological resilience, compassion, self-compassion, conscious awareness, design of habits, coping with loneliness, and coping with crisis is becoming apparent.

Research aims

The aim of this study is to examine cyberloafing and loneliness with its changing structure in terms of work psychology. In addition, the researchers and their results on cyberloafing and loneliness are discussed in terms of both sociodemographic factors and some variables of work life.

Methodology

The research method of critical analysis of literature on the subject of cyberloafing and loneliness was applied in this study. Common findings of secondary research were used in terms of work psychology.

Findings

The concepts of loneliness and cyberloafing, which have been evaluated in relation to different sociodemographic and work-life factors and whose mutual relations have been the subject of a very limited number of studies, are examined more intensively in the context of personal and organisational factors applicable to the technology-intensive future.

The article is devoted to the history of the planning and making of intervention of USA and South Vietnam into Laos in February-April 1971. The operation was named «Lam Son 719». The invasion group was to destroy the infrastructure of material support of People‟s Army of Vietnam (PAVN) – «Ho Chi Minh Trail». The work is built with the assistance of a memoir – translations memories combatants in Laos, soldiers and commanders of Army of United States America, South Vietnam and Democratic Republic of Vietnam. The materials housed in the monographs of American and Vietnam researchers of the Indochina conflict, 1960–1970-s.In 1971 amid the withdrawal of US troops from Indochina, American administration made a decision to invade Laos. The main target of the intervention was destroying the objects of «Ho Chi Minh Trail» in the southeastern regions of the kingdom. With a success of ARVN in Laos, the PAVNs combat effectiveness is seriously reduced. This operation was critical test of Vietnamization. «Lam Son 719» had to demonstrate high combat capability of ARVN. The victory was supposed to strengthen international credibility of USA. In 8 February 1971, Army of the Republic of Vietnam (ARVN) invaded into kingdom. The command of PAVN, having guessed the enemy's plan, pulled together large forces in Lower Laos.

Published: September 2021

Objective: To study some parameters of peripheral blood depending on changes of echocardiographic indicators reflecting the presence of myocardial hypoxia in patients with coronary artery disease (CAD), arterial hypertension (AH), and in their combination. Methods: Examined 98 men at the age of 45 to 70 years, suffering from various clinical forms of CAD (n=41), stage I-III AH (n=35), and a combination of CAD and AH (n=22). The disease variants were spread as follows: acute myocardial infarction (n=4), atherosclerotic (n=9), post-infarction (n=5) cardiosclerosis, unstable (n=1), stable angina II-III functional classes (FC) (n=6), heart failure II-III FC (n=4), type 2 diabetes (n=4) patients. In all surveyed patients was taken the blood sampling from a vein in the morning on an empty stomach to obtain serum. The study program included cardiac echo with an assessment of standard parameters. The LV mass (LVM) was determined using the Penn Convention formula. The obtained volume indicators were indexed in relation to the surface area of the body, calculating the LV mass index (LVMI). Results: In patients with CAD and with combined CAD and AH in comparison with patients with AH (without CAD) indicators of LVM and LVMI were comparatively lower (due to high blood pressure), though they more often revealed the cases of segmental LV hypokinesis and diastolic dysfunction of the LV. It could be partly due to the changes of morphofunctional properties of erythrocytes, the presence of a chronic inflammatory response, and the worsening of coagulation and rheological properties of peripheral blood. Conclusions: In patients with CAD and a combination of CAD and AH, in comparison with patients with AH (in the absence of CAD), there is increased deformability of erythrocytes, availability of indicators attesting the reaction of chronic inflammation, and a large degree of pathological changes in the rheological properties of blood. Keywords: Coronary artery disease, arterial hypertension, blood cells, chronic sluggish inflammation, coagulation properties of blood, dyslipidemia.

Objective: Improvement of the results and effectiveness of endoscopic treatment for arachnoid cysts of the middle cranial fossa (AC MCF) in children. Methods: At the Federal Center for Neurosurgery of Tyumen 65 patients with AC MCF were operated from 2012 to 2018 by endoscopic cystocisternostomy (ECCS). Patients age ranged from one month up to 17 years. Children under 3 years old were – 32 (49%). Hypertensive symptoms were in 26 (40%); delayed speech development in 20 (31%); symptomatic epilepsy in 12 (18.5%); pathology of the ocular fundus was in 5 (7.7%). Associated abnormalities were in 19 (29%). All patients underwent CT and/or MRI. In 46 (71%) patients, cysts were located on the right, in 13 (20%) on the left and 6 (9%) bilateral. The displacement of the middle structures was diagnosed in 45 (69%). According to the Galassi classification: type II was in 20 (31%), type III – in 45 (69%) patients. The average volume of AC MCF before the operation was 181±18.6 cm3. All 65 patients underwent ECCS: a miniature neuroendoscope KarlStorz – Endoskop 11576 KF/KG was used in 47 patients, and a standard rigid endoscope LOTTA, «Gaab I scope» or flexible video scope was used in 18 patients. Results: The postoperative observation period ranged from 1 year to 8 years. The volume of cysts after surgery averaged 124.8±17.2 cm3. On average, the volume of cysts decreased by 58.2±13.5 cm3. The total efficiency of ECCS in 65 patients with AC MCF reached 81.5% of cases. Relapse was noted in 14 patients (22%). The period of recurrence ranged from 1 month to 81 month. Recurrence was in 71% of children under the age of 3 years. There was a correlation between repeated interventions and age. Children under 3 years of age have the efficiency of surgical treatment at 68.8% than in children over 3 years old – 93.8% (p≤0.01). The results of surgical treatment, depending on the endoscope used, were statistically unreliable, because when using Karl Storz – Endoskop 11576 KF/KG the total efficiency was 81%, and when using LOTTA, «Gaab I scope» or a flexible video scope – 84%. Complications in the postoperative period occurred in 6 (9%) children. Conclusions: The effectiveness of ECCS in 65 children with AC MCF reached 81.5% of cases. The effectiveness of ECCS in children under 3 years of age was 68.7%, and 93.7% in children older than 3 years. Keywords: Middle cranial fossa , arachnoid cysts in children, intracranial cyst, endoscopic treatment, endoscopic cystocisternostomy.

A Language Course to Teach Administrative Staff English for Communication in an International University
Authors: Reynolds Barry Lee , Yu Melissa H.
Published: September 2021

A qualitative case study was conducted to triangulate student interviews, a teacher’s reflection report, and classroom observation data to understand how a local language course prepared Taiwanese administrative staff for international communication across working contexts in an international university. The findings firstly show that the teacher treated course planning as a teacher and student process of co-developing, co-moderating, co-revising, and co-managing learning resources and content. The teacher empowered the administrative staff by giving them the authority to select language targets for study that the staff thought would be useful to fulfil their job duties. Secondly, participation of the administrative staff was important in creating and managing language resources for international communication. The teacher used vocabulary and dialogue writing and speaking practices that were contextualised to the needs of the administrative staff. The targeted vocabulary was selected by the administrative staff based on gaps in their knowledge and was then used to co-construct dialogues that addressed scenarios the staff had previously encountered that necessitated the use of English with internationals. Thirdly, developing the course to address the administrative staff’s communication needs was a process of rebalancing teacher autonomy, learner autonomy, and course development. Both the teacher and the students perceived the course effective in encouraging practical changes in the administrative staff’s learning and use of English, which they mostly attributed to the non-formal nature of the course and the support from higher management. Implications for planning and implementing English language courses for international communication were drawn from the findings

Technology-Mediated Dangerous Behaviors as Foraging for Social-Hedonic Rewards: The Role of Implied Inequality
Authors:   University of Melbourne, Parkville, Turel Ofir
Published: September 2021

Technology-mediated dangerous behaviors (TMDBs), such as posting selfies while driving or posting private information, are prevalent and potentially require interventions. Knowledge about the drivers of these, and specifically the role of information in stimulating such behaviors, is limited. To address this gap, this paper turns to foraging and risk-sensitivity theories. These theories suggest that animals engage in more dangerous behaviors when their perceived need for calories is high. Similarly, humans increase financial risk-taking when they perceive dissatisfaction with what they have. Importantly, inequality information can increase such perceptions and change people’s risk-taking propensity. Adapting these ideas, the paper postulates that TMDBs resemble food-seeking in animals in that they are goal oriented, can be dangerous, and yield unknown (probabilistic) rewards. Therefore, TMDBs are explained using foraging and risk-sensitivity theory angles. Focusing on social media users (Studies 1-4; four experiments; total n = 2,504), I argue that (1) it is reasonable to view users as foraging the “fields of social media” for social-hedonic rewards, (2) it is possible to alter their risk appetite and TMDBs through inequality information and upward comparison mechanisms, (3) this process can be mediated not only through cognitions, but also emotions, and (4) perceived scarcity of rewards and social comparison orientation affect this process. With Study 5, the paper extends the core aspects of this theoretical perspective to the U.S. state level and argues that objective financial inequality can explain differences between states in terms of TMDBs such as texting while driving and relative interest in TMDBs such as prank videos. The findings largely support these assertions. They illuminate the role of information, notably inequality, in driving TMDBs, extend prior research focused on basic needs (e.g., physiological needs in the case of food intake decisions) to an evaluation of higher-order human needs (e.g., needs for belongingness, esteem, and self-actualization) catered to by nonphysiological, social-hedonic rewards, and point to important mechanisms that translate inequality into TMDBs.
When the Machine Meets the Expert: An Ethnography of Developing AI for Hiring
Authors:   Universiteit Amsterdam, van den Broek Elmira , Sergeeva Anastasia ,   Universiteit Amsterdam, Huysman Vrije Marleen ,   Universiteit Amsterdam
Published: September 2021

The introduction of machine learning (ML)in organizations comes with the claim that algorithms will produce insights superior to those of experts by discovering the “truth” from data. Such a claim gives rise to a tension between the need to produce knowledge independent of domain experts and the need to remain relevant to the domain the system serves. This two-year ethnographic study focuses on how developers managed this tension when building an ML system to support the process of hiring job candidates at a large international organization. Despite the initial goal of getting domain experts “out the loop,” we found that developers and experts arrived at a new hybrid practice that relied on a combination of ML and domain expertise. We explain this outcome as resulting from a process of mutual learning in which deep engagement with the technology triggered actors to reflect on how they produced knowledge. These reflections prompted the developers to iterate between excluding domain expertise from the ML system and including it. Contrary to common views that imply an opposition between ML and domain expertise, our study foregrounds their interdependence and as such shows the dialectic nature of developing ML. We discuss the theoretical implications of these findings for the literature on information technologies and knowledge work, information system development and implementation, and human–ML hybrids.

INVERSIVE SEMIOTIC ANALYSIS OF ROMAN OF F. SOLOGUB «LITTLE DEMON»
Authors: Лебедев Владимир Юрьевич , Прилуцкий Александр Михайлович
Published: September 2021

Данная статья является апробацией авторской методики инверсивного семиотического анализа и исследованием с помощью данной методики конкретного художественного текста - романа Ф. Сологуба «Мелкий бес». В основе инверсивного семиотического анализа лежит представление об инверсии - особом типе отношений в иерархических структурах, при которых низший элемент обретает главенствующие свойства, формально оставаясь на прежней, подчиненной позиции. Проведенные исследования позволили выявить в тексте романа различные уровни инверсии: в поведении и описании героев, изображении социальных и психических процессов. Это позволило сделать вывод о том, что инвертивность семиотических планов формирует семиотический код текста.

This article is an approbation of the author's method of inverse semiotic analysis and research with the help of this method of a specific literary text - the novel by F. Sologub «The Little Demon». Inverse semiotic analysis is based on the concept of inversion - a special type of relationship in hierarchical structures in which the lower element acquires dominant properties, formally remaining in the same subordinate position. The studies carried out allowed us to identify different levels of inversion in the text of the novel: in the behavior and description of the characters, in the depiction of social and mental processes. This made it possible to conclude that the inversion of semiotic plans forms the semiotic code of the text.

Authors: Sandoval Rosa Carolina , Roche Maxime , Belausteguigoitia Itziar , Alvarado Miriam , Galicia Luis , Gomes Fabio S. , Paraje Guillermo
Published: September 2021

Objetivo. Caracterizar el diseño de los impuestos selectivos al consumo de bebidas azucaradas en América Latina y el Caribe, y evaluar las oportunidades de aumentar su impacto en el consumo y la salud.

Métodos. Se llevó a cabo una búsqueda y una evaluación exhaustivas de legislaciones vigentes a marzo del 2019, recopiladas mediante las herramientas de seguimiento ya existentes de la Organización Panamericana de la Salud y de la Organización Mundial de la Salud, fuentes secundarias, así como mediante una encuesta a ministerios de finanzas. El análisis se centró en el tipo de productos gravados y la estructura y la base de estos impuestos selectivos.

Resultados. De los 33 países evaluados, en 21 se aplican impuestos selectivos al consumo de bebidas azucaradas. En siete países también se aplican impuestos selectivos sobre el agua embotellada y en al menos cuatro, se aplican tales impuestos sobre las bebidas lácteas azucaradas. Diez de estos impuestos selectivos al consumo son de tipo ad valorem con algunas bases imponibles fijadas en las primeras etapas de la cadena de valor, siete son de tipo específico y cuatro son de estructura combinada o mixta. En tres países se aplican impuestos selectivos al consumo en función de la concentración de azúcares del producto.

Conclusiones. Si bien el número de países en que se aplican impuestos selectivos al consumo de bebidas azucaradas es prometedor, existe una gran heterogeneidad en su diseño en cuanto a la estructura, la base imponible y los productos gravados. Se podrían aprovechar aún más los impuestos selectivos existentes para tener un mayor impacto sobre el consumo de bebidas azucaradas y la salud si se incluyeran todas las categorías de bebidas azucaradas, excluyendo el agua embotellada, y si se recurriera más a impuestos específicos ajustados regularmente según la inflación y basados posiblemente en la concentración de azúcares del producto. Todos los países se beneficiarían si hubiera mayor orientación. Futuras investigaciones deberían tener como objetivo abordar esta brecha.

Perinatal care experiences of immigrant Syrian women: a qualitative phenomenological study
Authors: Vurgec Burcu , Surucu Sule , Köroglu Cemile , Ezzo Hibe
Published: September 2021

Background: Adverse birth outcomes of immigrant women and neonates are associated with the quality of perinatal care. For this reason, examining immigrant women’s experiences of perinatal care is necessary if host country care systems are to respond appropriately to migration. Aims: The aim of the study was to evaluate the perinatal care experiences of immigrant women. Methods: The qualitative phenomenological design used in the study enabled to make an in-depth exploration of immigrant women’s experiences. The participants were 24 women who had a pregnancy within the past 6 months and lived in Adana, Turkey, between September and December 2019. Data were collected using a semi-structured form through the snowball method. Qualitative data were analysed using the thematic analysis method. Results: The participants’ mean age was 21.41 [standard deviation (SD) 3.86] years. Mean age at first pregnancy was 17.27 (SD 4.59) years. It was determined that immigrant women received insufficient maternity services. In thematic analysis, 4 main themes indicating barriers to sufficient perinatal care were identified. The barriers to maternal care services were: language barrier, cultural incompatibility, decreased social support and inadequate information. Conclusion: Our findings indicated that perinatal care for immigrant women was inadequate and their experiences were generally negative. Although the barriers seem separate, they are actually intertwined, with the language barrier appearing to be the main one. Innovative approaches are needed to solve this problem. Mobile applications that translate instantly can be used by both immigrant women and health care professionals.

Authors: KOKULU Kamil , SERT Ekrem Taha , MUTLU Hüseyin
Published: September 2021

Aim: Bedside ultrasonography (US) is a frequently used tool to facilitate diagnosis and treatment in emergency departments (EDs). The primary aim of our study was to evaluate the characteristics of emergency physicians’ use of bedside US. Our secondary aim was to analyze factors affecting the regular use of bedside US.

Material and Methods: This was a descriptive cross-sectional survey study conducted with physicians working in EDs. The study was carried out using a 15-item questionnaire in 2020, and the results were analyzed with the Statistical Package for the Social Sciences software.

Results: The questionnaire was sent to 965 physicians working in the EDs of 48 different hospitals, and the data of 684 (71.5%) that responded to all items in the questionnaire were included in the study. The EDs of the hospitals included in the study had at least one US device, and 82% of them were equipped with three probes. It was observed that 152 (22.2%) of the emergency physicians did not use US at all, and 532 (77.8%) used US regularly, albeit rarely. The most common area of use for US in the ED was focused assessment with sonography in trauma, followed by procedural guidance (432 [63.2%] and 308 [45%], respectively]. Of the physicians who did not use bedside US regularly, 33.3% (n=96) stated that they did not use it due to their lack of training. In addition, the interest of emergency physicians in US education was measured as 7±3 points. It was observed that the conditions associated with frequent use of bedside US were gender, inclusion of US training during residency, and duration of the availability of an US machine in the emergency clinic.

Conclusion: This study showed that emergency physicians had a high interest in using bedside US. The greatest obstacle to the use of US was insufficient training. Therefore, emergency physicians should be offered regular US training programs sand those that have not received US training should be encouraged to participate in such programs.

Authors: SARI Ferdi , ÖZŞAHİN Murat , ZİROĞLU Nezih
Published: September 2021

Amaç: Bu çalışmada, amatör olarak spor yapan ve ön çapraz bağ (ÖÇB) rekonstruksiyonu yapılan bireylerde, operasyonun fonksiyonel sonuçları ve sportif aktiviteleriyle olan ilişkisinin araştırılması amaçlandı.

Gereç ve Yöntem: Ön çapraz rüptürü nedeniyle dört katlı hamstring otogrefti ile artroskopik rekonstrüksiyon uygulanan hastaların fonksiyonel sonuçlarını Lysolm ve Tegner aktivite skorlama sistemi ile retrospektif olarak anali ettik. Kinezyofobi değerlendirilmesi Tampa ölçeği kullanarak yapıldı.

Bulgular: Çalışmaya dahil olan 61 kişinin tamamı erkekti (yaş dağılım: 17 - 48 yıl, ortalama: 30.6±6.9). Takip süresi en kısa 27 ay iken en uzunu 74 ay olmak üzere ortalama 47,4 ay idi. Ameliyat öncesi ortalama 59,1 (dağılın: 5 - 90) olan Lysholm skoru son kontrolde 95,9’du (dağılın: 69 - 100). Tegner aktivite skorları ortalaması travma öncesi 6,4 (dağılın: 3 - 10), ameliyat sonrası 5,2 (dağılın: 3-10) idi. Tampa kinezyofobi ölçeği 41.2 (29-49) bulundu.

Sonuç: Cerrahi sonucunda, hastaların çoğunda fonksiyonel sonuçlar tatmin edici olarak tespit edilirken, yaklaşık yarısında ise aktivite skorları istenilen düzeye ulaşmıştı. Tampa kinezyofobi ölçeği yüksek bulunması, ÖÇB cerrahisinde ne kadar titiz davranılsa da ameliyat önce ve sonrasında alacağı profesyonel fizyoterapi ve psikolojik danışmanlığın da önemli derecede etkili olabileceğini gösterdi.

Purpose: Evaluating the relationship between tinnitus intensity, noise sensitivity, health anxiety and depression in adult individuals with tinnitus complaints.

Material and Methods:190 individuals aged 19 and over having tinnitus complaints for at least one year were included in the study. In the study, the General Information Form (GIF), Tinnitus Disability Questionnaire (TDQ), Weinstein Noise Sensitivity Scale (WNSS), Health Anxiety Inventory (HAI) and Depression Anxiety and Stress Scale Short Form (DASS-21) were used and delievered to the participants online. SPSS 22.0 was used for the statistical analyses.

Results: The mean scores of individuals with tinnitus complaint were 49.73±29.40 for TDQ, 56.82±17.94 for WNSS, 19.96±13.90 for DASS-21, 18.33±9.69 for HAI. Tinnitus intensity of 28.6% of people with noise sensitivity was very mild, 12.7% was very severe. A positive correlation was found between the total score of the TDQ and the scores of the DASS-21. A negative correlation was found between the WNSS scores and the total score of the TDQ. There was a statistically significant difference between the upper 1/3, lower 1/3 and middle classification values of the WNSS total scores and the TDQ classification groups. A positive correlation was found between the total score of the TDQ and the HAI and its sub-dimensions (p

El objetivo de la investigación es evaluar la concentración de cadmio y plomo en testa y cotiledón de almendras de cacao, para determinar en qué parte de la almendra existe mayor acumulación de estos metales, el método aplicado para la cuantificación de cadmio y plomo fue la espectroscopia de absorción atómica en horno de grafito, también se determinó parámetros físicos-químicos como humedad, pH y acidez; las muestras de cacao fueron recolectadas en 5 fincas productoras ubicadas en el sector La Adelina, cantón Balao. En los resultados obtenidos se determinó un porcentaje de humedad menor al 2% con respecto a las muestras de las 5 fincas; el pH es inversamente proporcional con la acidez, en la finca 1 la testa fue la que presentó un pH mayor de 3,34 con un porcentaje de acidez bajo de 2,4%. En lo que corresponde a la evaluación de metales pesados, se determinaron una ligera concentración de cadmio y plomo en la testa del cacao, los cuales se encuentran dentro de los límites permisibles por el Códex Alimentarius. Sin embargo se debe tener un control ya que a futuro dichos resultados podrían verse influenciados por la acumulación de estos metales
ASSAY AND GRAPHITE FURNACE- ATOMIC ABSORBANCE SPECTROMETRY ACCURACY FOR PALLADIUM CONTENT ANALYSIS
Authors: Irzon Ronaldo , Kurnia
Published: September 2021

Palladium is a member of the expensive Platinum Group Metals as it is indispensable for various applications of modern technology. Due to the very small number of these elements in nature, high-sensitivity analytical methods and devices are required for accurate PGM measurement. The current study aims to determine the accuracy level of the Graphite Furnace-Atomic Absorbance Spectrometry device for palladium analysis after pre-concentration through the assaying process. The studied samples were two in-house standard reference samples with stream sediment and ultramafic rock matrices. Due to the lack of certified reference material containing certain palladium compositions, the degree of accuracy was tested by the spiking method. The detection limit for Pd in this study was 11.79 ppb. Pd content in the stream sediment (17 ppb) is much lower than of the ultramafic sample (290 ppb), implying PGM association to ultramafic rock naturally. Almost all measurements have good accuracy according to spike recovery between 80-120%. Inaccurate addition process and inappropriate calibration range most probably lead to inaccuracy.

DME has characteristics similar to LPG so that the storage and handling are not so different from LPG. DME could be used as a solvent that can extract typical types of rubber/polymer material. The aims and objectives of this study are to determine the effect of DME/LPG (100/0, 80/20, 50/50, 30/70, 20/80) on the stability of the DME/LPG mixture on the stove and also to observe the effect on several rubber materials/polymers on stove accessories. The study reveals that the usage of a DME/LPG mixture between 20/80 - 30/70 does not require a replacement of any substitute materials but only requires minor modifications to the stove. However, at a higher DME composition, the use of the fuel needs to replace the seal that is resistant to DME. It occurs due to the change of the gas composition when it is used.

This study proposed a supply chain network for determining suppliers’ location in which the transportation costs are a piecewise linear function. The supply chain network consists of a production facility, suppliers, and customers. These types of costs are found in the fields of transportation, logistics, and purchasing discount. First, the supply chain network is formulated as the mixed-integer non-linear programming (MINLP) because piecewise linear transportation cost makes the model non-linear. Then, the model is transformed into a mixed-integer programming (MIP) model using the convex-combination method to overcome this nonlinearity. The model was used for solving the problem faced by a small and medium enterprise (SME) in Cilegon. The MIP was solved using the CPLEX software. Sensitivity analysis was carried to provide the SME with several alternatives in handling the suppliers’ location problem

The potential risk of radioactive release to the environment and surrounding population can occur when there is a nuclear emergency, and nuclear preparedness planning is required for disaster mitigation. In preparedness planning, data is needed, one of which is demographic characteristics. Demographic information in site preparation can produce appropriate and efficient policy formulations because the number and density of the population, as well as the susceptible population, are known. The method used is secondary data collection, data verification, data processing, mapping, and analysis. This study aims to determine the demographic characteristics of the site vicinity. The study results show that the population density in 5 km radius area is 177 people/km2. In 2018, the total population was 5,199 people, the percentage of the male population was 50.3%, and the female population was 49.7%. The population aged ?20 years was 63.4%, 5-19 years old was 29.7%, and aged 0-4 was 6.9%. The projected population in 2047 is 6,523 people. The assumption is that in the event of a nuclear emergency, the emergency response considers the susceptible population. Evacuation of residents related to the emergency response can be carried out through 2 routes, namely through the South Singkawang District to the West Singkawang area, which is about 30 km from the site or through the Sungai Raya District to the Sungai Kunyit area, which is of about 26 km from the site.

Síndrome da Veia Cava Superior: Um desafio para o Internista de um Hospital Distrital
Authors: Gaudêncio Ana Margarida , Faria Sara , Batista Filipa , Almeida Patrícia , Bessa Isabel , Pereira Amélia
Published: September 2021

A síndrome da veia cava superior surge quando existe uma diminuição ou obstrução do fluxo venoso da cabeça, pescoço e membros superiores através da veia cava superior por trombose ou compressão extrínseca da mesma. Pode ter diversas etiologias, sendo a causa neoplásica uma das mais frequentes, constituindo uma urgência oncológica. Numa abordagem inicial, o uso de corticoterapia e diuréticos endovenosos, combinado com a elevação da cabeceira são medidas fundamentais. Para além disso, o tratamento da doença de base, radioterapia de urgência e radiologia de intervenção são as opções mais viáveis. Os autores propõem-se apresentar uma série de casos que surgiram no serviço de urgência de um hospital distrital durante o período de um ano. Dois casos surgiram em doentes com neoplasias já conhecidas e em tratamento, sendo as neoplasias em questão - linfoma MALT brônquico e carcinoma papilar da tiroide com metastização pulmonar e mediastínica. Outro dos doentes tinha uma formação nodular a nível do lobo superior direito do pulmão, sem identificação histológica. No outro caso, esta síndrome foi a apresentação inicial, tendo os exames complementares demonstrado a presença de massa mediastínica, biopsada através de mediastinoscopia, que revelou linfoma difuso de grandes células B. Os doentes apresentavam idades compreendidas entre os 61 e 81 anos. Para todos, foi pedido apoio ao hospital de referência pela inexistência de radiologia de intervenção e radioterapia no nosso hospital. A síndrome da veia cava superior pode apresentar várias etiologias, tendo os casos descritos ocorrido em contexto de doença oncológica. Esta série de casos alerta-nos para o desafio clínico e sobretudo terapêutico num hospital distrital, assim como, reforça a importância de equipa multidisciplinar e inter-hospitalar para a melhor orientação dos doentes, procurando oferecer as melhores alternativas terapêuticas.
