Authors: Park Hyejin , Kim Kisok
Published: March 2018

Humans are exposed to the environmental pollutants 2, 4-dichlorophenol (2, 4-DCP) and 2, 5-dichlorophenol (2, 5-DCP) through air, use of water and consuming products. In this study, we evaluated the urinary concentrations of these compounds in Korean people from the age of 18 to 69 years by making use of the data from the Korean National Human Biomonitoring Survey that was completed in 2009. Of 1,865 representative Koreans, 63.4% and 97.9% were found to have concentrations of 2, 4-DCP and 2, 5-DCP > 0.05 μg/L (limit of detection) in their urine. The geometric mean urinary concentrations were 0.14 μg/L (confidence interval of 95% = 0.13–0.16) and 0.44 μg/L (confidence interval = 0.41–0.48), respectively. It was fond that the adjusted proportional changes in 2, 4-DCP concentrations were significantly associated with body mass index, whereas those of 2, 5-DCP concentrations were influenced by place of residence. From these findings, it is evident that most adults in Korea have levels of 2, 4-DCP and 2, 5-DCP that are detectable in their urine and burden of these compounds on their bodies varies depending on numerous demographic factors.

Diabetes melitus adalah suatu penyakit gangguan kesehatan di mana kadar gula dalam darah seseorang menjadi tinggi karena kekurangan insulin atau reseptor insulin tidak berfungsi baik. Banyak orang awalnya tidak tahu bahwa mereka menderita diabetes mellitus, di negara-negara Asia lebih dari 50 persen (bahkan ada yang mencapai 85 persen) penderita diabetes baru mengetahui diri mereka mengidap diabetes setelah mengalami komplikasi di berbagai organ tubuh (Tandra Hans, 2007). Ketidaktahuan ini disebabkan karena minimnya informasi mengenai diabetes, gejala dan minimnya tenaga dokter spesialis diabetes. Sistem pakar adalah program komputer yang menirukan penalaran seorang pakar dengan keahlian pada suatu wilayah pengetahuan tertentu (Turban, 1995). Sistem pakar mencoba mencari solusi, memberikan saran atau kesimpulan yang konsisten terhadap permasalahan yang ditemukannya.   Penulis berhasil mengimplementasikan sebuah sistem  pakar berbasis web yang dapat mengatasi nilai derajat kepercayaan atau faktor kepastian data yang diperoleh dari hasil konsultasi dengan pasien melalui metode certainty factor. Harapan penulis, sistem ini dapat membantu dokter atau masyarakat awam sekalipun dalam mengambil keputusan ketika mendiagnosa penyakit diabetes mellitus. Kata Kunci : Sistem Pakar, Certainty Factor

Published: March 2018

In the past, web-based chat application didn’t consider security as part of must-have requirement, thus many insecure examples were broken in short time after it was released. Data sniffing is one common attack that could be used to attack insecure applications because the data was transferred using an insecure medium, which is HTTP. We propose a new web-based chat application that is built based on HTML5 WebSocket technology using Socket.IO library to improve confidentiality of the messages sent between two or multiple parties. We combine it with NodeJS and Express to facilitate real-time discussion between client and server and vice versa. We also use Rijndael (known as AES - Advanced Encryption Standard) to make sure that the message stays confidential and only known by sender and receiver. To satisfy the integrity property, we apply SHA-3 hash function. By combining SSL/TLS, AES, and SHA-3 hash function, we have added multiple layer of security inside this application and no additional effort needed by the user. Based on conducted experiments, we can conclude that this application could satisfy security requirements (confidentiality and integrity), either on the client or server side.

Published: March 2018

Honey bees (Apis mellifera) are constantly exposed to contact with many types of pathogens. However, during evolution they developed a number of immune mechanisms. At the individual level, they comprise 1) resistance mechanisms associated with anatomical and physiological barriers of the body, 2) cell-mediated immunity involving hemocytes (including plasmocytes, lamellocytes, and granulocytes), 3a) congenital humoral resistance related to the activity of lysozyme (N-acetylmuramylhydrolase), the prophenylooxidase system (ProPO) and hemagglutinins (lectins), and 3b) induced humoral resistence based on the action of antimicrobial peptides: apidicines, hymenoptecin, and defensins. In addition to the individual resistance of each bee, there is also a defense mechanism activated at the colony level. Shared secretion resistance is connected with the presence of antipathogenic compounds in secreta and in bee products. Social immunity is associated with hygienic and nursing behaviors, as well as with age polyethism in the colony, swarming (and the emergence of rebel workers), and the changing behavior of sick individuals. Many aspects and interactions between different types of resistance and immunity still remain unexplored. However, current research trends revolve around clarifying uncertainties so as to strengthen the natural resistance of bees and fight against pathogens that threaten the insects..
Az 1851–1910 közötti időszak vándorlástörténetének újragondolása (I. rész)
Authors: Faragó Tamás
Published: March 2018

Az alábbi elemzés itt közölt első részében a történeti Magyarország első világháború előtti vándorlástörténetének forrásadottságaira, valamint a források elemzési problémáira összpontosítunk, és a vándorlások típusait és nagyságrendjét igyekszünk meghatározni. A megszokottól némileg eltérve együtt tárgyaljuk a belső és a  nemzetközi vándorlási folyamatokat, tekintettel arra, hogy hajtóerejük, motivációjuk  sok tekintetben hasonló volt, és nem egy esetben méreteik és a résztvevők által megtett távolságok sem igen különböztek egymástól. Bemutatjuk a különböző alapvető vándorlási típusok (kivándorlás, bevándorlás, visszavándorlás) statisztikai adatait az 1907 és 1913 közötti hivatalos statisztikai adatok alapján. Ezt követően ismertetjük a  vándorlások mérlegét mérő vándorlási különbözet területi eltéréseit, és kitérünk olyan  belső vándorlási típusokra is, melyeket a vándorlástörténeti kutatások gyakran elhanyagoltak: bemutatjuk a határmenti vándorlásokat Ausztria példáján, illetve ismertetjük a rövid távú vándorlások egyik legfontosabb típusát, a külterületekre történő vándorlást.
A lengyelországi migráció alakulása az 1800-as évektől napjainkig
Authors: Mikó Eszter
Published: March 2018

A Lengyelországból más országokba irányuló migráció hosszú múltra tekint vissza, amelyet az egyes történelmi időszakokban különböző tényezők motiváltak. A tanulmány elsődleges célja annak feltárása, hogy az elmúlt két évszázad során milyen főbb migrációs folyamatok indultak meg Lengyelországból. Különösen fontos az utóbbi évtizedek sajátosságainak feltárása, mert ez hozzájárulhat a jelenleg zajló magyarországi migráció jobb megértéséhez is. A történeti áttekintés alapjául a hozzáférhető lengyel statisztikai kiadványok, valamint a célországok és a nemzetközi szervezetek adatbázisai szolgáltak. A kutatás során nyilvánvalóvá vált, hogy napjainkban a lengyel migrációs folyamatok legfőbb motivációs tényezői – épp úgy, mint a többi kelet-középeurópai országban – a gazdasági tényezők. Elsősorban a fiatal korosztály jól képzett tagjai a résztvevői, és mára már megszűnt a korábbi férfi dominancia.

“Teachers are the real Nation builders”_ Nelson Mandela
Prospective teachers are the future goal setters. It is very important to monitoring how they
are learning and acquiring the practical and theoretical knowledge for the future development and
growth in the career profession. Simply learning and ignoring not at all a matter in the teacher
profession, but it is essential to follow them up and make the interpersonal relationships as part of
their life is necessary, because they can manage their profession in well respective manner and they
will enter into shape the younger minds and they my put mark of behaviour in the young brains and
really they will become the role models. This study needed to know the level of prospective teachers
interpersonal relationships and will help to assess their quality of teaching learning. The objectives of
the study were 1. To find out the level of interpersonal relationships of prospective teachers and
to classify them. 2. To find out the influences of the certain variables on the interpersonal
relationships of the prospective teachers. The sample of the present study was 150 prospective
teachers and adopted Normative Survey Method.
Use of Grading of Recommendations, Assessment, Development, and Evaluation to Combat Fake News: A Case Study of Influenza Vaccination in Pregnancy (Preprint)
Authors: Zafar Sidra , Habboush Yacob , Beidas Sary
Published: March 2018

BACKGROUND

The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework is a validated evaluation tool used to assess the quality of scientific publications. It helps in enhancing clinicians’ decision-making process and supports production of informed healthy policy.

OBJECTIVE

The purpose of this report was two-fold. First, we reviewed the interpretation of observational studies. The second purpose was to share or provide an example using the GRADE criteria.

METHODS

To illustrate the use of the GRADE framework to assess publications, we selected a study evaluating the risk of spontaneous abortion (SAB) after influenza vaccine administration.

RESULTS

Since 2004, the Centers for Disease Control and Prevention and the Advisory Committee on Immunization Practice have recommended influenza vaccination of pregnant women. Previous studies have not found an association between influenza vaccination and SAB. However, in a recent case-control study by Donahue et al, a correlation with SAB in women who received the H1N1 influenza vaccine was identified. For women who received H1N1–containing vaccine in the previous and current influenza season, the adjusted odds ratio (aOR) for SAB was 7.7 (95% CI, 2.2-27.3), while the aOR for women not vaccinated in the previous season but vaccinated in the current season was 1.3 (95% CI, 0.7-2.7).

CONCLUSIONS

Our goal is to enable the readers to critique published literature using appropriate evaluation tools such as GRADE.
A Hazard Analysis of Class I Recalls of Infusion Pumps (Preprint)
Authors: Gao Xuemei , Wen Qiang , Duan Xiaolian , Jin Wei , Tang Xiaohong , Zhong Ling , Xia Shitao , Feng Hailing , Zhong Daidi
Published: March 2018

BACKGROUND

The adverse event report of medical devices is one of the postmarket surveillance tools used by regulators to monitor device performance, detect potential device-related safety issues, and contribute to benefit-risk assessments of these products. However, with the development of the related technologies and market, the number of adverse events has also been on the rise, which in turn results in the need to develop efficient tools that help to analyze adverse events monitoring data and to identify risk signals.

OBJECTIVE

This study aimed to establish a hazard classification framework of medical devices and to apply it over practical adverse event data on infusion pumps. Subsequently, it aimed to analyze the risks of infusion pumps and to provide a reference for the risk management of this type of device.

METHODS

The authors define a general hierarchical classification of medical device hazards. This classification is combined with the Trace Intersecting Theory to form a human-machine-environment interaction model. Such a model was applied to the dataset of 2001 to 2017 class I infusion pump recalls extracted from the Food and Drug Administration (FDA) website. This dataset does not include cases involving illegal factors.

RESULTS

The proposed model was used for conducting hazard analysis on 70 cases of class I infusion pump recalls by the FDA. According to the analytical results, an important source of product technical risk was that the infusion pumps did not infuse accurate dosage (ie, over- or underdelivery of fluid). In addition, energy hazard and product component failure were identified as the major hazard form associated with infusion pump use and as the main direct cause for adverse events in the studied cases, respectively.

CONCLUSIONS

The proposed human-machine-environment interaction model, when applied to adverse event data, can help to identify the hazard forms and direct causes of adverse events associated with medical device use.
Self-Management and Self-Efficacy in Patients With Acute Spinal Cord Injuries: Protocol for a Longitudinal Cohort Study (Preprint)
Authors: van Diemen Tijn , Scholten Eline WM , van Nes Ilse JW ,   SELF-SCI Group, Geertzen Jan HB , Post Marcel WM
Published: March 2018

BACKGROUND

People with recently acquired spinal cord injury (SCI) experience changes in physical, social and psychological aspects of their lives. In the last decades, attention has grown for aspects of self-management and self-efficacy in SCI research. However, we still do not know what the self-management and self-efficacy outcomes of first rehabilitation are and whether utilizing these skills may prevent secondary health conditions (SHCs) and increase participation and psychological adjustment early after SCI.

OBJECTIVE

To describe the course and determinants of self-management and self-efficacy during and after first SCI rehabilitation; and to determine theory-based associations between self-management and self-efficacy with SHCs, participation and psychological adjustment.

METHODS

Multicenter prospective longitudinal cohort study. All people with a newly acquired SCI admitted to one of the 8 specialized SCI rehabilitation centers in the Netherlands will be considered for inclusion in this study. Main assessments will take place during the first and last week of admission and 3, 6 and 12 months after discharge. The target sample is 250 participants. The primary outcomes are self-management (knowledge and execution of self-care) and self-efficacy (confidence in the ability to manage the consequences of SCI and of self-care). Secondary outcome measures are SHCs, participation and psychological adjustment to SCI.

RESULTS

The first results with the complete set of data are expected in June 2019.

CONCLUSIONS

This protocol describes the SELF-SCI cohort study investigating self-management and self-efficacy of initial inpatient SCI rehabilitation. Second, associations will be investigated with SHCs, participation and psychological adjustment early after onset of SCI, until 1 year after discharge. The results will be used to test theories about motivation to perform health-promoting behaviors and adjustment to SCI.

BACKGROUND

Seventy percent of lifetime cases of mental illness emerge before the age of 24 years, but many youth are unable to access the support and services they require in a timely and appropriate way. With most youth using the internet, electronic health (eHealth) interventions are promising tools for reaching this population. Through participatory design research (PDR) engagement methods, Thought Spot, a Web- and mobile-based platform, was redeveloped to facilitate access to mental health services by transition-aged youth (aged 16-29 years) in postsecondary settings.

OBJECTIVE

The aim of this study was to describe the process of engaging with postsecondary students through the PDR approaches, with the ultimate goal of optimizing the Thought Spot platform.

METHODS

Consistent with the PDR approaches, five student-led workshops, attended by 41 individuals, were facilitated to obtain feedback regarding the platform’s usability and functionality and its potential value in a postsecondary setting. Various creative engagement activities were delivered to gather experiences and opinions, including semistructured focus groups, questionnaires, personas, journey mapping, and a world café. Innovative technological features and refinements were also brainstormed during the workshops.

RESULTS

By using PDR methods of engagement, participants knew that their ideas and recommendations would be applied. There was also an overall sense of respect and care integrated into each group, which facilitated an exchange of ideas and suggestions.

CONCLUSIONS

The process of engaging with students to redesign the Thought Spot platform through PDR has been effective. Findings from these workshops will significantly inform new technological features within the app to enable positive help-seeking behaviors among students. These behaviors will be further explored in the second phase that involves a randomized controlled trial.
