Published: December 2022

Dust from an electric arc furnace is formed as the main by-product of the
steel production process from the secondary iron-based raw materials. This
dust has significant contents of Zn and Fe, as well as Pb, Cd, Ca, Mg, Cr,
Mn, Si, Ni, Cu, F, Cl and other elements and is considered hazardous
industrial solid waste since it contains heavy metals. In order to protect
the environment and public health from the negative impact of this type of
hazardous waste, it is necessary, even mandatory, to carry out its treatment
in accordance with the legislation of the country where it is located.
Before applying any treatment of the electric arc furnace (EAF) dust, it is
necessary to perform its detailed characterization. In this paper, the
following characterization of EAF dust originating in the Republic of
Serbia was performed: physical-mechanical and chemical characterization,
determination of granulometric composition, and mineralogical
characterization. Also, the EAF dust impact on the environment and human
health was assessed (Leachability and Toxicity Characteristic Leaching
Procedure (TCLP) tests). The results have shown that the Zn content is in
the range 32 to 35 % and that the main mineralogical phases of the dust are
zincite, franklinite, magnetite, and magnesioferrite. Granulometric analysis
has shown that 80 % of the sample consists of particles less than 26 ?m in
size. According to the leaching test results, the EAF dust is characterized
as a hazardous waste due to the increased chloride content, while the TCLP
test indicated dust toxicity due to the increased contents of Zn, Cd, and
Pb.

OBJECTIVE

We investigated associations of living in a doubled-up household (i.e., adults living with adult children, other related adults, or other unrelated adults) with diabetes self-management behaviors, occurrence of diabetes preventive care services, and hospital use by Hispanic/Latino adults with diabetes.

RESEARCH DESIGN AND METHODS

We analyzed data from the second clinical visit (2014–2017) through subsequent annual follow-up interviews completed through January 2020 of all participants with diabetes in the Hispanic Community Health Study/Study of Latinos. Multivariable regression was used to test associations between doubled-up status with diabetes self-management behaviors (i.e., checking blood glucose level, checking feet for sores), diabetes preventive care services done by a doctor (i.e., dilated-eye examination, feet checked, hemoglobin A1c measured, urine analysis for kidney function), and hospital use (i.e., emergency department [ED] visits and hospitalizations).

RESULTS

Hispanic/Latino adults living doubled up were less likely to have their urine checked by a doctor for kidney disease compared with adults not in doubled-up households. Doubled-up status was not associated with diabetes self-management behaviors. Adults living doubled up in a household with other related adults had a 33% increased risk of ED visits compared with adults living doubled up in a household with adult children.

CONCLUSIONS

Health care settings where Hispanic/Latino adults with diabetes receive trusted care should add housing characteristics such as doubled-up status to social-needs screening to identify residents in need of connecting with housing or social services and more targeted diabetes management services.

The choice of contraception is very important. Usually, the acceptors choose the contraceptive that is easiest to use even though the device is not necessarily in accordance with the existing variables, causing errors in the selection of contraceptives and resulting in the failure of the family planning program. This study aims to build a decision support system that can assist in the selection of contraceptives. This study uses the Simple Additive Weighting (SAW) method using 7 criteria variables and a web-based system built. The results of the research conducted indicate that the decision support system built can help provide contraceptive recommendations based on calculations using 7 criteria. Other tests show that the functions contained in the system have been running well according to user needs.

Käytännöllinen satunnaistettu kontrolloitu tutkimus osallistavan ryhmämuotoisen palveluohjauksen vaikuttavuudesta

Published: December 2022

Osa yksin asuvista ikääntyneistä on vaarassa jäädä sekä sosiaalisten suhteiden että riittävien palveluiden ulkopuolelle. Heidän hyvinvointinsa edistämiseksi tarvitaan elämänlaatua kokonaisvaltaisesti tukevia interventioita ja tutkimustietoa niiden vaikuttavuudesta. Tässä tutkimuksessa tarkastellaan PROMEQ-tutkimushankkeessa kehitetyn ja pilotoidun osallistavan ryhmämuotoisen palveluohjauksen vaikuttavuutta. Tutkimuskysymyksenä on: Millaisia vaikutuksia osallistavalla ryhmämuotoisella palveluohjausinterventiolla on osallistujien koettuun elämänlaatuun, yksinäisyyteen, institutionaaliseen luottamukseen ja osallisuuteen (a) kuuden kuukauden pituisen intervention päättyessä ja (b) 15 kuukautta intervention aloittamisen jälkeen?  Osallistujien tarpeiden pohjalta ryhmäkohtaisesti räätälöity interventio sisälsi viisi ohjattua ryhmätapaamista, joiden lisäksi ryhmäläisiä kannustettiin omaehtoisiin lisätapaamisiin.
Tutkimus toteutettiin sosiaalipalveluiden tutkimuksessa harvinaisempana käytännöllisenä satunnaistettuna kontrolloituna tutkimuksena Jyväskylän, Kuopion, Eksoten ja Siun soten alueilla osana ikääntyneiden palveluohjausyksiköiden toimintaa. Tutkimukseen osallistui 392 yksin asuvaa 65–99-vuotiasta ikäihmistä (interventioryhmä: 185, kontrolliryhmä: 207), jotka kokivat haasteita hyvinvoinnissaan tai terveydessään. Tutkimusaineistona käytettiin alkukyselyä (0 kk) ja kahta seurantakyselyä (6 kk ja 15 kk). Vaikuttavuutta tarkasteltiin ensisijaisesti suhteessa elämänlaatuun (mittari: WHOQOL-BREF). Toissijaisia vaikuttavuusmuuttujia olivat yksinäisyys, institutionaalinen luottamus sekä osallisuus. Vaikuttavuusanalyyseissä menetelmänä käytettiin yleistettyä lineaarista mallinnusta (GEE).
Tuloksien mukaan interventiolla ei ollut merkittäviä vaikutuksia osallistujien elämänlaatuun, yksinäisyyteen, institutionaaliseen luottamukseen tai osallisuuteen heti intervention päättymisen jälkeen, eikä 15 kuukauden kuluttua sen alkamisesta. Lisäanalyysit osoittivat, että interventio voi vähentää yksinäisyyttä, mikäli interventioon osallistuneet jatkavat yhteydenpitoa toisiinsa järjestettyjen ryhmätapaamisten päätyttyä. Interventiota on mahdollista edelleen kehittää monitasoisen saatavilla olevan arviointitiedon pohjalta. Jatkossa tulisi myös kehittää luotettavia hyvinvoinnin eri osa-alueita mittaavia mittareita, jotka soveltuvat paremmin moniulotteisten sosiaalihuollon interventioiden ja hyvinvointia edistävien palveluiden vaikuttavuuden arviointiin.
Division of Chinese opinion on Russia-Ukraine War: Analyzing Key Actors’ Strategic Framing on Weibo
Authors: Sun Wenting
Published: December 2022

Is strategic framing in authoritarian regimes fully under the control of the government? How could opinions on the Russia-Ukraine war of Chinese key actors differentiate from each other? Based on strategic framing theory, we use Structural Topic Models (STM) and a computational corpus-based approach to conducting a discourse analysis of 576 blogs produced by Chinese media outlets and opinion leaders on Weibo, the most popular social media platform in China. We argue that the strategic framing of private media is internally linked and influenced by state media in terms of topic distribution, topic trending, and position. However, the neutral position of the state is designedly to give space for private media to challenge the dominant frame of the state, which reflects an actively weakening control over the media ecosystem in China.
