Sairaanhoitajien valmiudet tiedonhallintaan sekä kokemukset potilas- ja asiakastietojärjestelmien tuesta työtehtäviin

Sairaanhoitajien kokemuksia potilas- ja asiakastietojärjestelmistä kartoitettiin nyt toiseen kertaan valtakunnallisella kyselytutkimuksella. Tutkimuksen tavoitteena on tuottaa tietoa kansallisessa Tieto hyvinvoinnin ja uudistuvien palvelujen tukena – Sote-tieto hyötykäyttöön 2020 -strategiassa asetettujen tavoitteiden saavuttamisesta yhden osa-alueen (Kyvykkäille käyttäjille fiksut järjestelmät) osalta sairaanhoitajien näkökulmasta. Näitä strategian osatavoitteita mukailevat tutkimuskysymykset ovat: Miten asiakas- ja potilastietojärjestelmät tukevat hoitajien työtehtäviä, yhteistyötä ja tiedonkulkua? Minkälaiseksi hoitajat arvioivat nykyisen käyttökokemuksensa, koulutuksensa, perehdyttämisen toimintatapojen muutokseen sekä lisäkoulutustarpeensa? Miten hyödylliseksi hoitajat arvioivat asiakas- ja potilastietojärjestelmät työssään?
 Tutkimusaineisto kerättiin sähköisellä kyselyllä hyödyntäen Sairaanhoitajaliiton, Tehyn sekä Akavan sairaanhoitajat ja Taja ry:n (TAJA) jäsenrekistereitä keväällä 2020. Kyselyyn vastasi hyväksyttävästi 3 610 sairaanhoitajaa, kätilöä tai terveydenhoitajaa, jotka toimivat julkisessa terveydenhuollossa, sosiaalihuollossa tai yksityisellä sektorilla. Vastaajat olivat kokeneita asiakas- ja potilastietojärjestelmien käyttäjiä. Valtaosa heistä kirjautui vähintään yhteen järjestelmään päivittäin, osa jopa viiteen tai sitä useampaan järjestelmään. Tulosten mukaan vastaajat eivät olleet tyytyväisiä järjestelmien tukeen niiden käytön vaatiman pitkän perehdytyksen vuoksi. Tiedonkulkuun hoitajien välillä omassa organisaatiossa oltiin tyytyväisiä, mutta tiedonkulussa eri organisaatioissa toimivien hoitajien välillä sekä hoitajien ja potilaiden välillä koettiin puutteita. Enemmistö vastaajista koki tietotekniset perustaitonsa, taitonsa tehdä kirjaukset asiakas- tai potilastietojärjestelmään, taitonsa tehdä potilaan hoidon kirjaus hoitotyön prosessin mukaisesti sekä tietosuojan ja tietoturvan periaatteiden hyödyntämisensä päivittäisessä työssä hyviksi tai erinomaisiksi kaikissa toimintaympäristöissä. Yli puolet vastaajista ei ilmoittanut lisäkoulutustarpeita. Kuitenkin hoitajat toivoivat työnantajiltaan enemmän täydennyskoulutusta. Vastaajat kokivat ongelmalliseksi järjestelmien kyvyn tai toiminnallisuuden koostaa yhteenvetonäkymiä. Yhteenvetona voidaan todeta sairaanhoitajilla olevan hyvät tai erinomaiset taidot käyttää asiakas- ja potilastietojärjestelmiä, mutta perehdytystä tarvitaan tukemaan digitaalisten palvelujen tuottamissa työprosesseissa. Hoidon jatkuvuus, laatu ja potilasturvallisuus ovat erityisesti hyötyjä, joita tietojärjestelmien käytöllä jo saavutetaan.

Tietojärjestelmät sairaanhoitajien työn tukena eri toimintaympäristöissä: kokemuksia tuotemerkeittäin

Asiakas- ja potilastietojärjestelmät ovat sairaanhoitajien työssä keskeisiä työvälineitä. Artikkelissa selvitettiin, missä määrin eri asiakas- ja potilastietojärjestelmät tukevat sairaanhoitajien työtä eri toimintaympäristöissä. Tavoitteena oli tuottaa tietoa kansallisen tiedonhallinnan strategian täyttymisestä ja sairaanhoitajien käyttäjäkokemuksista palautteeksi tietojärjestelmätoimittajille.
 Tiedonkeruu sairaanhoitajien tietojärjestelmäkokemuksista toteutettiin keväällä 2020 kyselynä. Kyselyyn vastasi 3912 sairaanhoitajaa, joista pääosa työskenteli julkisessa sairaalassa, terveyskeskuksessa, sosiaalialalla tai yksityissektorilla. Yleisimmin käytettyjä asiakas- ja potilasjärjestelmiä olivat yleisyysjärjestyksessä Lifecare asiakas- ja potilastietojärjestelmä (Lifecare), Uranus, Pegasos, Apotti (tuotemerkki: Epic), Effica terveydenhuolto (Effica), Mediatri, Esko, DynamicHealth ja DomaCare. Kyselyn väittämistä raportoitiin teemoja, jotka koskevat tietojärjestelmien kykyä tukea vuorovaikutusta (4), hyötyjä (4), käytettävyyttä (2), teknistä toimivuutta (3) sekä paperin ja faksin käyttöä (1), tietojärjestelmille annettavia kouluarvosanoja (1) ja järjestelmätoimittajille suoraan annettavaa palautetta (30). Kysely tehtiin sairaanhoitajille toista kertaa, ja pohdinnassa tarkasteltiin muutoksia vuoteen 2017 nähden.
 Tulosten mukaan tietojärjestelmien tuki sairaanhoitajien työlle parantui tai pysyi ennallaan monien muuttujien osalta. Tulokset vaihtelivat asiakas- ja potilastietojärjestelmien tuotemerkkien ja toimintaympäristöjen välillä ja myös samojen tuotemerkkien välillä eri toimintaympäristöissä. Sairaanhoitajat olivat tyytyväisiä etenkin tietojärjestelmien kykyyn tukea yhteistyötä ja tiedonkulkua sairaanhoitajien kesken organisaation sisällä sekä sairaanhoitajien ja lääkärien välillä. He myös kokivat, että tietojärjestelmät tuottavat hyötyjä asiakkaiden ja potilaiden hoitoprosessille. Toisaalta organisaatioiden välisessä tiedonkulussa turvauduttiin edelleen paperiin ja faksiin. Lisäksi vastaajat tunnistivat asiakas- ja potilastietojärjestelmissä enemmän työtä hankaloittavia kuin hyvin toimivia ominaisuuksia. Vaikka tietojärjestelmien kehityssuunta vaikutti positiiviselta, eivät ne kaikilta osin edelleenkään tukeneet sairaanhoitajien työtä riittävällä tasolla ja näin ollen tietojärjestelmien systemaattista seurantaa on syytä jatkaa.

Sosiaalialan ammattilaiset halukkaita osallistumaan asiakastietojärjestelmien kehittämiseen – osallistumistavoissa kehitettävää

Tietojärjestelmien kehittämistyön lähtökohtana tulee olla vahva ymmärrys käyttäjien tarpeista, tehtävistä sekä toimintaympäristöstä. Lisäksi suunnitteluratkaisuja tulee arvioida käyttäjien kanssa kehittämisprosessin aikana ja käyttöönoton jälkeen. Vaikka kansallisesti kohdennetaan runsaasti resursseja tietojärjestelmäpalveluiden kehittämiseen, sosiaalialalta tutkimusta aiheesta löytyy niukasti.
 Sosiaalialan ammattilaisten kokemuksia asiakastietojärjestelmien kehittämistyöstä kartoitettiin osana keväällä 2019 toteutettua valtakunnallisesta käyttäjäkokemuskyselyä. Kysymyksissä käsiteltiin kokemuksia yhteistyöstä tietojärjestelmätoimittajan kanssa, osallistumisesta kehittämistyöhön ja osallistumistavoista tietojärjestelmien kehitykseen. Tuloksia tarkasteltiin asiakastietojärjestelmän tuotemerkeittäin.
 Puolet vastaajista ei ollut osallistunut lainkaan kehittämistyöhön, mutta vain 19% ei ollut halukkaita osallistumaan ollenkaan. Suosituimmat osallistumistavat olivat ongelmien raportointi järjestelmien kehittämisen vastuuhenkilölle ja oman työn esittely kehittäjille; sen sijaan tietojärjestelmätoimittajien yleisimmin käyttämät tavat eli palautteen kirjaaminen verkkosivustolle tai sähköpostiin eivät olleet käyttäjien mieleen. Suurin osa tiesi, miten ongelmatilanteista ja kehitysehdotuksista raportoidaan.
 Sosiaalialan ammattilaiset ovat kiinnostuneita osallistumaan kehittämistyöhön, mutta he eivät ole tyytyväisiä mahdollisuuksiin ja tapoihin osallistua käyttämiensä järjestelmien kehittämiseen. Järjestelmätoimittajien ja käyttäjien väliltä puuttuvat sopivat toimintatavat. Tulokset ovat samansuuntaisia kuin vastaavissa lääkäreille ja sairaanhoitajille tehdyissä tutkimuksissa. On myös mahdollista, että organisaatiot eivät hyödynnä innokasta kehittäjäpotentiaalia. Kehittäjien tulee jalkautua kentälle ja organisaatioiden palkata tietojärjestelmäkehityksestä vastaavia ammattilaisia tulkeiksi järjestelmätoimittajan ja käyttäjien välille. Sosiaalialan ammattilaisten näkökulma on huomioitava vahvemmin järjestelmäkehityksessä, jotta tietojärjestelmät saadaan onnistuneesti tukemaan sote-yhteistyötä tulevaisuudessa.

A Qualitative Study on the Experience of Elderly Men Caring Their Wives in Japan

본 연구는 일본의 남성노인 돌봄 경험을 통해 최근 증가하고 있는 한국에서 아내를 돌보는 남성노인에 대한 시사점을 얻는 것을 목적으로 한다. 이를 위해 돌봄 기간이 1년 이상이면서 공식적 돌봄을 이용하고 있는 일본 남성노인 5명을 심층 인터뷰 하였다. 자료 분석은 일반적 질적 연구 분석 방법에 근거하였다. 분석 결과, 5개의 범주가 도출 되었다. 범주는 <돌봄 마주하기와 책임성>, <부담되는 현실과의 직면>, <돌봄 경험의 익숙해짐>, <돌봄 속박의 굴레>, <돌봄의 관계적 경험>이다. 이를 통해 ‘부부관계, 남편으로서의 도리’ 등과 같은 사회적 가치가 돌봄 책임을 수용하는 요인이었으며, 다양한 공적 서비스들이 남성노인의 돌봄 유지에 깊이 관여하고 있는 것으로 파악되었다. 특히 개호보험 제도의 케어매니저 서비스는 남성노인들의 돌봄 전반에 영향을 미치고 있었으며, 다양한 가족지원 서비스 이용은 남성노인들의 돌봄과 일생생활에 부담 감소와 자유를 주는 것으로 나타났다. 따라서 부부간 개입의 중요성, 공식적 돌봄을 통한 돌봄 윤리의 실천 가능성, 고립의 위험성을 시사해 주었다. 분석 결과를 토대로 기존 여성 중심으로 이루어진 노인 돌봄지원 정책에 대한 조정, 한국형 케어매니지먼트 도입, 다양한 서비스의 지원이 한국사회에 필요함을 제언하였다. 마지막으로 장기요양서비스 이용자 외의 돌봄 경험을 살펴보지 못했다는 점과 대도시에 거주하는 남성노인의 경험만을 제한적으로 살펴보았다는 점이 본 연구의 한계라 하겠다.The purpose of this study is to grasp the implications for male elderly care in Korea, which has recently been on the rise through Japan s experience in male elderly care. Five elderly Japanese men providing cares for their wives for more than a year with formal care were interviewed in depth. The data analysis was based on a general qualitative research analysis method. The results were derived from the following five categories: facing care and responsibility, facing the burden of reality, the familiarity with care experience, the ties with burdens of care, and the relationship-oriented experience of care. Social values such as ‘marriage relationship’ and ‘husbandry’ were the main factors that accepted care responsibilities. Various formal LTC services were found to be deeply involved in sustaining care for male elderly people. In particular, the care management service was affecting the overall care and everyday life of the elderly, and the use of various services was found to give freedom to the care life of the elderly. These findings imply the importance of an intervention to one marital unit as a client system, the practicability of care ethics through formal care, and the special needs of isolation of men elderly. Based on these results the study suggests that the Korean society needs to adjust the existing women-centered care policy, to introduce Korean-style care management, and to support various other services for male elderly care givers.

Learning and Applying Mindfulness to Relational Client Systems: A Phenomenological Analysis of CMFT Students’ Experiences in a Mindfulness Course

The benefits of mindfulness have been well established in mental health research, and many couple, marriage, and family therapists (CMFTs) incorporate mindfulness techniques into clinical practice. Despite its widespread use, there is a dearth of literature examining CMFTs’ experiences with mindfulness education within the MFT field. Using a participatory research design, our study analyzed 35 journal entries of seven CMFT graduate students (N = 7) enrolled in a 5 week, summer mindfulness course within a COAMFTE-accredited program. Data were analyzed using the immersion/crystallization phenomenological technique. Findings illuminated 12 themes, all relating to CMFTs’ experiences of learning and applying mindfulness techniques in clinical practice. These themes were grouped within three categories that corresponded with our research questions (Role of the Mindfulness Class, Personal Mindfulness Experience, and Application of Mindfulness in Clinical Practice). Clinical and training implications for CMFTs are discussed throughout.

USAGE OF SESSION METRICS TO TASKS SCHEDULING IN BROWSER-BASED VOLUNTEER COMPUTING SYSTEMS

Context. The study is devoted to the development an adaptive method for scheduling tasks in distributed browser-based volunteer computing systems. which is constructed on the session metrics of a volunteer user. This allows server to allocate tasks to each volunteer for computing, depending on the characteristics of his computing processes. More productive clients will receive more tasks, maximizing resource utilization, reducing server load and facilitating scaling; less productive clients will receive fewer tasks, solving the problem of excessive blocking of input data.Objective. The aim of the study is increasing the efficiency of distributed browser-based volunteer computing systems by using session metrics to tasks scheduling.Method. The session metrics that determine the behavior of volunteer users are described. The indicators that characterize the progress of the computational process on user systems were introduced. The formula to calculate the amount of input data for distribution to client is proposed. It takes into account the capacity of the client's system and the tendency of processes on its system. Simulation was done using different methods to calculate the amount of input data on the basis of the existing system of volunteer computing. To evaluate the performance of such systems, the total number of user hits to the server part and the total number of calculated results were used.Results. The proposed method is applied in the existing browser-based volunteer computing system. A comparison of the results of the proposed method with the existing ones showed a decrease in server load and an increase of the number of calculated results when session metrics are used.Conclusions. The simulation confirmed the convenience and efficiency of session metrics usage to tasks scheduling. The presented approach provides scalability of distributed browser-based volunteer computing systems. The prospects of further research are to use the users’ statistics and information from their browsers to calculate the amount of input data for distribution to client.

Digital Forensics in private Seafile Cloud Storage from both client and server side

Nowadays, some people and organisations are unwilling to store their information on public clouds due to security and privacy problems. With increased use of established cloud services by cloud software, it is possible for malicious users to use these services for criminal purposes, so digital forensic investigations of these cloud services are necessary. Seafile cloud storage is one of popular cloud that is free and open source. In this paper, we document a series of digital forensic experiments on Seafile cloud storage service with the aim of providing forensic researchers and practitioners on both the client and server sides of Seafile. Data remnants are checked on client systems in virtual machines which running Windows 10 Home operating system and on a server with Windows Server 2012 R2 operating system. Different circumstances are created for digital forensic examinations. Correspondingly, Seafile client software and multiple browsers are used for interaction with Seafile cloud server.

Lessons from the Transition to Relational Teletherapy During COVID-19.

When the World Health Organization declared the coronavirus outbreak a pandemic, clinicians were challenged to maintain continuity of care. Teletherapy became the primary means of service delivery for many who had never or only sparingly used it. The Family Institute at Northwestern University, in response to encouraging findings with respect to the effectiveness of teletherapy and recognizing advantages with respect to access to care, launched our teletherapy services in 2018. As a relationship‐based organization, we were keen to exploit the opportunity that teletherapy provides to integrate additional members of the client system into the treatment. Over these two plus years, we have learned a great deal. Our learning was greatly accelerated by our transition to a 100% teletherapy practice in the wake of the pandemic. Teletherapy is a different context. Intentionally managing the context’s constraints and exploiting its strengths is key to providing high‐quality couple and family therapy. This step is often overlooked or resisted when teletherapy is an occasional add‐on to a face‐to‐face practice.

Homeless Shelter Flows in Calgary and the Potential Impact of COVID-19.

Social distancing and self-isolation are two of the key responses asked of citizens during a pandemic. For people without a home, this advice is rather more difficult to follow. In this article, we use daily data describing the movements of 36,855 unique individuals who used emergency homeless shelters in Calgary over the period 1 January 2014–31 December 2019. We show that the use of emergency shelters is characterized by large flows from and into the broader community and smaller flows between individual shelters. Between admissions of new people into the shelter system and multiple re-admissions of current clients, there were an average of 43,613 movements between the community and between shelters each month. The size of these flows provide a measure of the extent to which people reliant on homeless shelters are exposed to the risk of transmission of coronavirus disease 2019 (COVID-19). By identifying the size and nature of these flows, we hope our analysis helps identify responses that may minimize this population’s risk of exposure.

BAHAYA LABELING NEGATIF TERHADAP PEMBENTUKAN KONSEP DIRI PADA ANAK TUNALARAS DENGAN TIPE GANGGUAN PERILAKU (CONDUCT DISORDER) DALAM PERSPEKTIF KONSELING LINTAS BUDAYA

Negative labeling is a form of negative stigma given by individuals or groups to other individuals or groups through a negative assessment of the deficiencies they have. Someone who is labeled will experience a change in role and tend to behave like the label given to him. One of them is tunalaras children who often get negative labels from people around because they experience obstacles in the development of emotional, social or both aspects, so that behavior tends to deviate, not in accordance with the age and demands of social norms prevailing in the environment. In this study, we will discuss the effects and dangers of negative labeling on children with disabilities with the type of conduct disorder on the formation of self-concept seen from a cross-cultural counseling perspective. If the problem is viewed through a cross-cultural perspective, negative labeling is an act that can cause social inequalities, for that children with conduct disorder really need cross-cultural counseling where cross-cultural counseling plays a role in helping the process of defining goals that are consistent with life experiences and values. the child's cultural values, recognizing the child's identity to include individual, group, and universal dimensions, supporting universal use and cultural specific strategies and roles in the healing process, and balancing the importance of individualism and collectivism in the assessment, diagnosis, and treatment of clients and client systems

Questioning questions in psychotherapeutic practice: The dialogical dynamics of change in therapy through clients questioning therapists

The focus of this study is a particular type of questioning in psychotherapy: The unusual, yet recurrent, phenomenon of clients asking questions or making requests to the therapist and the way this alters the dialogical dynamics and therapeutic alliance between the two. Thus, we investigate how these types of question-answer cycles challenge the balance of the dialogical system of therapy including the normally accepted asymmetrical power relation between therapist and client. The analysis is informed by an ecological perspective which views the dialogical collaboration of therapist and client as forming a distributed cognitive system. The study shows how disaffiliation to questioning cycles on one hand stress the dialogical system through changing the language game, yet on the other hand, also entertain a subtle form of cooperativeness. The questioning cycles inform the dyadic system of therapist and client so that precautions can be made in order to secure the therapeutic alliance.

‘Preparation’ and ‘Readiness’: The Education Paradigm for the Organisation Development Certificate Programme

The organisation development certificate programme (ODCP) offered by the Indian Society for Applied Behavioural Science—ISABS ( www.isabs.org ) is a unique blend of learning about organisations, the process of OD with deep awareness about self as an instrument of change. ISABS as an institution has been engaged with T-groups for the past 50 years, having learnt the same from National Training Laboratories (NTL) Institute for Applied Behavioural Science ( www.ntl.org ). The focus of ISABS has been on discovering oneself through the process of engagement in small groups. ISABS pedagogy has evolved over years after initial learning from NTL This pedagogy distinguishes itself from any typical university education by stressing on experiencing and reflection of the learning process held together by a process facilitator. The expectation is that the participants will conceptualise and apply their learning through their own volition. However, this needed to change for the ODCP programme. This article unfolds the process for the reader. The process of OD is based on the quality of the interaction/engagement between the client system and the OD practitioner. Hence, the quality of the ‘preparedness’ and ‘readiness’ of the OD practitioner plays a big role in the ‘process of OD’. ISABS addresses the twin issues of ‘preparedness’ and ‘readiness’ of participants to enter the field of OD through a pedagogy that is a combination of experiential, cognitive, reflective and peer learning. In addition, OD competencies and values are internalised through a learner-centred approach to teaching, classroom as organisation simulations and support systems provided through coaching and learning facilitation.

Client Module with Multifactor Authentication for Remote Electronic Signature Generation Using Cryptography API: Next Generation

In classic PKI systems, users resorted to cryptographic devices like smartcard or electronic-token to perform the required cryptographic operations, therefore all cryptographic operations will be done in a safe environment. Although a widely-accepted and highly-efficient method, along with the evolution of technology, it is also desirable to simplify user experience with the applications and at the same time to reduce costs. Thus, there is the problem of cryptographic devices and passwords needing to be retained and secret. To overcome all these impediments, we introduce the concept of remote signing, a concept that will simplify the signature generation process, and also increase security to the whole process while lowering costs for equipment. Therefore, by the fact that the signature generation process will be delegated to a remote service, the possibility of generating errors due to the client system is minimized, the need for a cryptographic device for users is eliminated. At the same time, the entire computational effort is also delegated to the remote service, which means an increased computing speed, and by the fact that the cryptographic devices that generate the signature are located at distance, there is also the possibility of physical securing and limiting unauthorized access.

RETRACTED ARTICLE: Secure storage allocation scheme using fuzzy based heuristic algorithm for cloud

Cloud computing is a paradigm in the modern era for the development of secure storage and secure job scheduling process in a cloud-based system. The cloud technology provides a user interface in the sense of raw data management with the relational databases to improve flexibility and scalability. Fuzzy-based Heuristic algorithm is proposed for secure storage allocation in a cloud environment. In this work, client systems are clustered using a fuzzy-based rule mechanism. The server generates a distributed public key using RSA for ensuring security and resolve memory recycling issues. It enhances the usage of the client over the cloud data storage in secure manner. It also improves the efficiency of data storage globally by implementing heuristic techniques. The K-nearest neighbors approach is used for efficient query searching for data storage in the clusters by the client. The proposed load-balanced scheduling approach enhances power consumption and efficiency. In the simulation, the results reveal that the proposed scheme provides better performance than existing approaches in terms of load balancing with security.

Experimental Analysis and Evaluation of RaptorQ Codes for Video Multicasting Over Wi-Fi

This paper presents a reliable and efficient high quality video streaming solution for use in challenging outdoor environments over Wi-Fi. An application layer forward error correction based on RaptorQ codes was implemented in a practical Wi-Fi based server and client system to enhance reliability. Thus, this paper presents the first detailed analysis on the implementation of RaptorQ codes for streaming high definition video over Wi-Fi. The measurements were performed in central Bristol with parameters such as RaptorQ symbol size, code rate, buffering time and modulation and coding scheme, and user quality of experience based on these parameters was evaluated. For multicast live video streaming it is demonstrated that system performance is mostly dominated by hardware and software limitations on constrained host platforms where the incoming packet rate exceeds the device`s ability to consume the traffic, i.e., Wi-Fi clients are a major source of packet loss, even in ideal channel conditions. Client limitations were found to be a function of modulation and coding schemes and RaptorQ coding parameters. Therefore, the optimum system design parameters such as RaptorQ symbol size, code rate and buffering time with respect to modulation and coding schemes were suggested considering practical limitations from real-world measurements.

A two-stage fuzzy neural approach for credit risk assessment in a Brazilian credit card company

This study explores and evaluates the use of soft computing systems for clients’ credit risk assessment in a Brazilian private credit card provider through the development of an innovative two-stage process, both involving soft computing techniques (fuzzy and neural networks). We use commercially available credit score ratings both in the development of our method and for benchmarking. After describing the development of our method, we present a discussion about the comparison of performances of our method and a number of other credit scoring methods described in literature (for e.g. statistical and soft computing-based). One of the analyzed existing methods for instance involves the use of a soft computing algorithm only – Artificial Neural Networks (ANN) – for client classification into solvent or non-solvent, having a market available credit score rating as input. One of the most relevant contributions of this study however is the development of what we consider an innovative approach for credit scoring. This is a two-stage process that involves the use of a fuzzy inference model as input for an ANN model (what we call a fuzzy-neural approach), using commercially available credit score ratings as response in order to conduct the fuzzy reasoning step of the analysis. The main conclusion of our research is that, in general, our fuzzy-neural method had better results than the pure application of some market available score rating method as input to a Multi-Layer Perceptron (MLP) since it was able to reduce uncertainty by improving predictability and reducing variability of the outcomes when compared to a model with no scores. The performance of a combination of a fuzzy and a neural method was very satisfactory; the vagueness usually present in the information of a company’ database was to a certain extent, incorporated by our method with good results. From the practical perspective, although our method has not proved to be substantially better than market available options, we demonstrated that it is possible for companies to develop credit score rating mechanisms internally based on past data by using fuzzy inference systems. Under certain circumstances, companies may find this option preferable than the usual option of paying high fees to large credit scoring agencies for the use of their proprietary systems.

Recognizing Animals as an Important Part of Helping

The beneficial role of companion animals on human health and wellbeing across the life span is well documented in the rapidly expanding multi disciplinary body of literature known as human animal interactions (HAI). Social workers practice at the interface of people and their diverse environments. The presence of human animal bonds (HAB) within client systems, between people and companion animals in particular, are increasingly acknowledged and valued by social workers. Additionally, some social workers incorporate animals in their practice through animal assisted interventions (AAI). However, there is a paucity of empirical literature on social workers’ knowledge about and experiences with the inclusion of animals. We conducted a survey across three prairie provinces in Canada, replicating a study that was first implemented nationwide in the U.S. and later in the Canadian province of Nova Scotia. The survey explored social workers’ knowledge of HAI in social work. The results, similar to the Nova Scotia and U.S. findings, suggest that s social workers have general knowledge about HAI and the HAB, and that some do incorporate animals in practice. Social workers seem to have increasing knowledge and skills about HAI. While this is a positive trend, there is nonetheless a need for specialized education and training on the beneficial impact that companion animals can have on social work practice. In this paper, the application of zooeyia within social work is adopted as one approach to understanding HAB. Important implications for human health and wellbeing and social work practice at the practitioner and organizational levels are discussed.

EKA v1: Emergency Call Auto-register, an Emergency Warning System based on Internet of Things for Intensive Care Patient at Hospital

The emergency calling device for nurse is generally located in every ward of a hospital. It is an important facility for every inpatient. However, generally these devices are still in the form of conventional electrical components that uses long wiring. This is because this system must reach all inpatient rooms. In addition, the caller feature is also very limited, usually only in the form of an emergency button. The caller system is also not yet integrated with the hospital database, so it becomes an obstacle for nurses and doctors to understand the patient’s condition in an emergency. This article discusses the design of a nurse calling device that is connected wirelessly via a wifi network on the ward. There are also several types of calling features so that the nurse or doctor immediately knows the type of assistance a patient needs. In addition, the client and server system is integrated with the hospital database, which shows a detailed patient history. This device uses the NodeMCU ESP 8266 board as a client and Raspberry Pi 3 as a server. The features placed on this device work well as a design and are successfully implemented for one ward per server.
