Classification of Subdivision Land Use and Land Cover Using Deep Learning Models
Authors: Jeong Bongseok , Lee Sunmin , Lee Moung-jin
Published: January 2025

Land cover provides crucial information related to biological geography, ecological climatology, and human activities. In the past, land cover mapping was performed based on visual interpretation, but it had limitations in terms of time and cost. Recently, it has become possible to create land cover maps with higher temporal resolution over wider areas using artificial intelligence-based models. The accuracy and reliability of AI model-based land cover maps increase with the amount of training data, but it is difficult to acquire large amounts of data due to the time required for label data annotation. In South Korea, the Environmental Geographic Information Service provides self-learning data consisting of aerial orthoimages and subdivision land cover classification level label data, making it possible to collect high-quality data. Therefore, this study examined the feasibility of self-learning data by building and evaluating a U-Net-based land cover classification model for waterfront areas using self-learning data. The trained model showed relatively low performance with an F-1 score of 0.61 for training data and 0.31 for test data. The model’s low performance is thought to be due to insufficient training caused by the large number of classification categories (34) and data imbalance between categories. Although the model performance using self-learning data was low, it is believed that model performance can be improved by grouping classification categories according to research purposes or resolving data imbalance through data augmentation techniques. Therefore, self-learning data is expected to be utilized in various studies using land cover.
Strategically Timed Voluntary Disclosures before Conferences: Global Evidence
Authors: Wang Emily Jing , Wang Shiheng
Published: January 2025

This study examines how firms strategically time their voluntary disclosures before attending conferences in the global market. We document four findings. First, conference firms provide more voluntary disclosures of positive news and experience better stock performance in the month before conferences than in the month after. Second, firms that attend low-visibility conferences, have limited conference experience, face greater shareholder pressure, or have less concentrated ownership are more likely to increase their voluntary disclosures of positive news before conferences. Third, non-U.S. firms domiciled in jurisdictions with stronger investor protection and financial institutions are more likely to increase their voluntary disclosures of positive news and experience a stock price run-up before conferences. Finally, positive news disclosures before conferences attract more favorable market reactions to conference presentations and greater analyst following and institutional holdings. Overall, conference firms in the global market strategically coordinate their disclosures to maximize the economic impacts of conference attendance.

Properties of New Partially Crystallized Lithium Disilicate CAD-CAM Materials
Authors: Wells JM , Johnson JW , Lien W , Raimondi C , Caballero M , Gibbons TF , Vandewalle KS
Published: January 2025

Objective:

The purpose of this study was to compare the optical, mechanical, and biological properties of two new, inexpensive lithium disilicate (LS2) materials (Lodden (LOD), LD Medical Technology; and BeautyZir (BZ), BeautyZir Technology) to a clinically established LS2 material (IPS e.max CAD (EMAX), Ivoclar Vivadent).

Methods and Materials:

The optical properties of the translucency parameter (TP) and opalescence parameter (OP) were obtained with a dental spectrophotometer. The mechanical properties of flexural strength (FS) and flexural modulus (FM) were determined through a three-point bend test conducted using a universal testing machine. Biocompatibility tests were conducted by analyzing cell proliferation using spectrophotometric absorbance (optical density) to determine relative growth rate and cytotoxicity. Representative specimens of the three LS2 materials were analyzed with X-ray diffraction to determine the relative crystalline phases. Data were analyzed with oneway ANOVA and Tukey’s post hoc test (α=0.05).

Results:

Significant differences in optical and mechanical properties were found amongst the groups (p<0.05). Both LOD and BZ had significantly greater TP and OP compared to EMAX. EMAX and LOD had greater FS and FM than BZ. No significant differences in optical density or relative growth rate were found among any of the LS2 groups (p>0.05). EMAX and LOD had greater weight percent of lithium disilicate than BZ.

Conclusions:

The new lithium disilicate LS2 material, LOD, exhibited better optical properties while maintaining mechanical and biological properties similar to the established LS2 material, EMAX.

Modeling of Monthly Solar Radiation by Climatic Variables and its Impacts on Human and Animal Health
Authors: RR Osés , GG Saura , DR Fimia
Published: January 2025

In this work the radiation corresponding to the monthly values of the year 2000 is modeled and the historical data for all
the other years of the database of the city of Santa Clara, capital of Villa Clara province, Cuba is estimated using the Objective
Regressive Regression (ORR). A model that explains 100 % of the explained variance was obtained, which represents an
important tool to provide climatic services of radiation without having an actinometric station. The variables that entered
into the equation were the monthly minimum temperature of the Yabu station and the monthly precipitation of the Yabu,
Sagua and Caibarién meteorological stations. As the minimum temperature increases by 1°C the radiation decreases by 4.8
Watt/m2. With respect to rainfall, there are different impacts, some positive, such as Yabu and Caibarien, and others negative,
such as in Sagua la Grande. A rainfall of 100 mm in Sagua can cause a decrease in radiation in Santa Clara of 89 Watt/m2. It is
recommended to extend this model to neighboring stations changing only the minimum temperature of these stations in order
to have the radiation data of these stations.

Anti-IgE Treatment in Allergic Rhinitis
Authors: W Thabet
Published: January 2025

IgE plays a central role in the physiopathology of allergic
rhinitis (AR). The binding of IgE-antigen immune complexes
to mast cells triggers their degranulation and the release
of inflammatory mediators, with the recruitment of other
effector cells (eosinophils, basophils). This is the basis for
the use of anti-IgE antibodies in the treatment of allergic
diseases where we classically found high serum IgE levels.
Nutrition and Psychology: A Review on the Impact of Diet on Mental Health
Authors: S Dhananjay , S Luxita
Published: January 2025

Depression and anxiety are the most common mental health diseases in the world and are the leading causes of disability. Even
in addition to diagnosis, depression and anxiety symptoms affect the well-being and functioning of many of the population.
Therefore, new approaches are needed to treat both clinically diagnosed and subclinical depression and anxiety. In recent
years, the relationship between nutrition and mental health has attracted considerable interest. Epidemiological studies have
shown that maintaining healthy or Mediterranean diets (high-fiber, vegetables, nuts and legumes, moderate-fiber poultry,
eggs and dairy products, and occasional red meat) reduces the risk of depression. However, the nature of these relationships
is complex due to the obvious possibility of reverse causality between diet and mental health. Mediterranean and traditional
diets are good for maintaining mental health. High sugar, saturated fat and ultra-processed foods should be avoided to support
mental health. Food can help us feel more. Psychological factors such as stress, mood and dietary disorders can affect food
habits and food choices. Good food is more important than good food and healthy food to maintain mental health.
Phobia
Authors: N Manseur
Published: January 2025

Phobias, multiple and very varied, are usually referred to neurotic functioning. However, phobogenic processes are located at
the crossroads of various pathologies of mental functioning, and certain phobias can reflect more archaic functioning. Phobias
are linked to anxiety, an unpleasant affect intrinsic to the human condition.
Although not all anxieties become phobias, it is because there is prior anxiety that a phobia is created. As soon as, invested
impulsively, the ego and the object are distinguished, anxiety is experienced. If this can be linked to a representation, then, thus
weighted, be projected outside, to become fear, fear of something, the place of perceptive projection becomes the phobogenic
object. The subject can then avoid anxiety as long as he does not encounter the perception that has become phobogenic, and
as long as the connection between anxiety and perception remains solid.
The earliest phobogenic situations are those of solitude, darkness and silence, the princeps phobias of the small child that
Freud describes in Inhibition, Symptom, Anxiety (1926). The child desires the presence of his mother and she is not there, nor
anyone nor anything. Once the representation of the object of desire is repressed, anxiety remains. To populate the emptiness
of the room that is suddenly too small or too large, the slightest perception becomes phobogenic; including the moon or the
beating of the heart. Better a ghost, an imaginary mouse, than the deafening silence of no one. A shadow, a noise, however
phobogenic they may be, come to populate the nothingness.

Published: January 2025

The study was conducted at ICAR-National Dairy Research Institute, Karnal, Haryana, India during Feb–May 2023 to find out the age window at which the bull produces quality semen. Fifteen Sahiwal bulls were selected and classified into three age groups (n=5 in each group) -(2–3.5), (>3.5–8) and (>8–12) years. Semen was collected twice a week with two ejaculates on each  collection. Fresh and extended frozen semen was analysed at fortnightly interval. The data was subjected to statistical analysis by one-way Analysis of Variance (ANOVA) using SPSS software version 26.0 to draw scientific inferences. The results revealed that the mean value of semen volume (ml), sperm concentration (106 ml-1), mass motility was high (p<0.05) in the >8-12 age group. Individual motility was high (p<0.05) in the >3.5–8 age group. Mean value of viability (%), HOST (%), Acrosome integrity (%) was lower in 2-3.5 age group for fresh as well as frozen semen. Post thaw motility was high (p<0.05) in >3.5-8 age group. In incubation test, the post thaw motility of the >3.5–8 age group was high (p<0.05) at 0, 90 and 120 min. Therefore, it can be concluded from the study that semen quality of Sahiwal bulls is influenced by age and it is better to use Sahiwal bulls only after 3.5 years of age and best semen quality is obtained from bulls of >3.5-8 years of age.

In the study period, samples were collected from different district of Gujarat viz., Ahmedabad, Navsari and Valsad. In which two species of the fruit bats, P. gigantus (n=4) and C.sphinx (n=10) were screened for the morphometric identification. Based on morphometry both the species were identified. The haematology was performed in 27 fruit bats (Pteropus giganteus, n=13; Cynopterus sphinx, n=14) and biochemical analysis was carried out in 28 fruit bats (Pteropus giganteus, n=16; Cynopterus sphinx, n=12). In haematology, mean Hb, PCV and TLC were observed higher in P. gigantus than C.sphinx, whereas the value of TEC was lower. Between the species and sexes, hemoglobin and packed cell volume (PCV) values were comparatively equal, indicating similar oxygen-carrying capacity.  In serum biochemistry, mean value of Creatinine, ALT, Total protein and BUN was observed higher in P. gigantus, whereas the AST was found high in C.sphinx. In comparison between male and female, the higher value of Creatinine and Total protein were found in male, whereas ALT, AST and BUN was found higher in female.

Published: January 2025

The study was conducted at the Department of Veterinary Anatomy, College of Veterinary Science and Animal Husbandry, Nanaji Deshmukh Veterinary Science University, Jabalpur, Madhya Pradesh, India, from January to June, 2020. It involved the hearts of 18 prenatal and 12 postnatal normal, healthy goats (Capra hircus). The heart was located in the ventral part of the thoracic cavity, within the middle mediastinal space, enclosed by the pericardium. In groups I and II, the heart appeared oval, while in groups III, IV and V, it assumed a flattened cone shape, reflecting progressive maturation. The heart weight relative to body weight was highest in group I and lowest in group V, indicating a gradual reduction in relative heart mass with age. A significant positive correlation was found between body weight and both heart weight and volume, with heart volume increasing consistently across all groups. The cranial border of the heart was longer than the caudal, while the coronary fat increased progressively from group I to group V, contributing to the functional efficiency of the heart. The heart’s transverse diameter exceeded the sagittal in all groups, reflecting lateral growth, while the left ventricular wall was significantly thicker than the right ventricular wall and the interventricular septum, a structural adaptation to higher pressure loads in systemic circulation. These findings provide valuable insight into the anatomical development and physiological adaptations of the heart across prenatal and postnatal stages in goats, contributing to a better understanding of cardiovascular growth patterns in this species.
Linguagem, comunicação e espetáculo, profanação e política
Authors: Buchard Alan Barbosa , Nascimento Daniel Arruda
Published: January 2025

Intencionamos mobilizar, nas linhas que se seguem, os conceitos de linguagem, comunicação, espetáculo e profanação, tais como retidos pelo filosófico italiano Giorgio Agamben, especialmente na relação com a política e com as suas exigências. Além de fazer saltar do corpo da obra essas realidades conceituais para trazê-las ao debate, gostaríamos de mostrar como há uma implicação explícita entre esses conceitos no fundo contínuo do seu projeto filosófico. A tarefa da profanação, que se apresenta diante de nós em um mundo político supostamente secular e, ao mesmo tempo, experimentalmente religioso, não pode ser compreendida sem que se considere o que significa a linguagem. A partir de uma frequente exploração de fontes primárias e secundárias, esperamos correr nas imediações do experimentum linguae para nos aproximar do poder profanatório da linguagem humana.
Campos de Carvalho e o Diabo
Authors: Tommaso Mario
Published: January 2025

O artigo busca contextualizar e analisar a entrevista concedida por Campos de Carvalho ao Jornal de Letras, em setembro de 1959. Na recepção à obra do autor, argumentos morais são empregados à guisa de juízo estético, positiva ou negativamente. Contra ambos, o autor se insurge, propondo uma ruptura com os paradigmas metafísicos que orientavam tais leituras. Sua autorrepresentação como pactuário do “Diabo” aparece na entrevista, confundindo persona ficcional e escritor – que a crítica já havia embaralhado –, no contexto de uma polêmica sobre a legitimidade do tema da loucura em seus livros. A entrevista, como intervenção crítica, reinventa o próprio escritor como entidade ficcional e devolve respostas iconoclastas às formulações contra a obra e o autor. Nela, “Diabo” equivale à figura de uma imanência radical, horizonte da ficção nonsense de Carvalho.
Mann Wislawa a outra
Authors: Costa Luana Signorelli Faria da , Ferreira Luis Henrique Garcia
Published: January 2025

O poema “Thomas Mann”, da poeta contemporânea Wislawa Szymborska (1923-2012), será comentado em seus aspectos temáticos e formais. Além da intertextualidade do título, serão contemplados os potenciais vínculos com o modernista que dá nome ao poema – Thomas Mann (1875-1955), nesse diálogo entre dois Prêmios Nobel. O poema “Thomas Mann”, repleto de termos biológicos, provoca um diálogo produtivo com o romance Doutor Fausto (1947), no qual o protagonista Adrian é influenciado pelo racionalismo do pai cientista. Levanta-se a hipótese de que, pela sutileza metafórica de suas escritas, ambos os autores confrontam regimes desumanizantes como o nazismo. Em contraponto a esse esvaziamento do humano, eles propõem uma visão plural do humanismo, estabelecendo uma crítica social comum ao tempo deles e que ainda hoje resvala em questões do tempo presente. Como aparato de pesquisa, serão usadas biografias: Donald Prater (2000), para Thomas Mann, e Bikont e Szczęsna (2012), para Wislawa Szymborska.
Celebração dos elementos
Authors: Veloso Rodrigo Felipe
Published: January 2025

Este trabalho pretende investigar a relação construída em Celebração dos elementos, de Henriqueta Lisboa, no que tange à Literatura, à Antropologia e à Psicanálise. Para estudo do texto poético em apreço, aplicar-se-ão os aparatos teórico-metodológicos dos ritos de passagem e da alquimia junguiana, uma vez que tal relação e processo acontecem na medida em que o indivíduo vai se conhecendo e passando por estágios durante a vida, em contato com o outro, com a natureza humana e social. Sendo assim, os elementos naturais (água, ar, fogo e terra) são temas e imagens presentes nos poemas em Celebração dos elementos, sobretudo, representam toda a concepção simbólica e significativa do texto literário e, além disso, constituem a extensão da vida subjetiva, portanto, da própria Henriqueta Lisboa, no ato de criação. Na análise, serão utilizados os autores Arnold Van Gennep (2014), Carl Gustav Jung (2018), Gaston Bachelard (1998), dentre outros.

METHODS AND MEANS OF REAL-TIME MEASUREMENT CONVERSION TARGETED AT SENSOR SYSTEMS
Authors:   Lviv Polytechnic National University, Lviv, Ukraine, Baran R. D.
Published: January 2025

At present, distributed control and management systems are becoming increasingly complex, with the number of Internet of Things devices and wireless sensors steadily growing. All of them require the development and improvement of simple and efficient devices for performing computational operations near sensors in real time.
This paper analyzes the use of number-pulse functional converters with variable bit width for computational operations near the sensitive elements of smart sensors in distributed real-time control systems. The key advantages of such devices are their simplicity, reliability, and energy efficiency. The introduction of feedback allows for a comprehensive improvement of the converters' characteristics. Basic structural elements with positive and negative feedback are known, and they exhibit certain differences among themselves.
Numerous studies and analyses of the obtained results for various functions (inverse proportional, logarithmic with different bases, square root, division devices, and others) offer new approaches to creating more advanced structures. This proposed work continues earlier research in the field of number-pulse information processing devices. However, unlike previous publications, it focuses on improving the mathematical principles underlying the computational process and the structural organization of such devices. The study covers aspects of the creation and investigation of combined feedback.
To address the identified problem, the method based on a new approach to combining measurement converter circuits with positive and negative feedback has been improved to enhance metrological characteristics. Additionally, a refined mathematical model with combined feedback has been developed, which has enabled a twofold improvement in calculation accuracy at the beginning of the conversion range.
The proposed methods and tools for performing arithmetic operations and elementary mathematical functions can serve as fundamental computational components for various cases of functional signal conversion in the form of number-pulse codes. These signals can be received from primary measurement sensors or special modeling devices with frequency or number-pulse outputs in real time.
The principle of variable bit width for building such devices enables easy scaling of the bit width of structural elements to extend the dynamic range of the input code within any specified limits.
THE USE OF FRACTAL CONVERTINGS AND THEIR SYSTEMS IN THE ENCRYPTION – DECRYPHATION OF MONOCHROME IMAGES
Authors:   Lviv Polytechnic National University, Lviv, Ukraine, Kovalchuk A. M.
Published: January 2025

Fractals occupy a rather important and defining place in computer graphics. This is the construction of landscapes, trees, plants, even animals and the generation of fractal textures, as well as fractal image compression. Modern physics and mechanics are just beginning to study the behavior of fractal objects. And of course, fractals are used directly in mathematics itself, as well as in cryptography when protecting images.
The article describes the use of elements of the RSA algorithm in fractal quadratic transformations and systems of fractal transformations for encryption / decryption of monochrome images. Images are one of the most used types of information. Because of this, protecting images from unauthorized use and access is an urgent task. The main condition for creating image protection is the assumption that the image is a stochastic signal. This allows us to transfer classical signal encryption methods to the case of images. But the image is such a signal that, in addition to the typical informativeness of data, also has visual informativeness, which brings new challenges to the protection problems. In fact, creating an attack on an encrypted image is possible in two cases: through traditional hacking of encryption methods, or through methods of visual image processing (methods of extracting contours, filtering, etc.). The latter do not provide a complete reproduction of the input image, but provide an opportunity to obtain some information from the image. In this regard, another requirement is put forward to encryption methods in the case of their use in relation to images – complete noise of the encrypted image. This is necessary in order to prevent the use of visual image processing methods.
Therefore, the urgent task is to develop such a use of the RSA algorithm in order to: preserve the resistance to decryption and ensure full noise of the image in order to make it impossible to use the methods of further visual image processing. One of the ways to solve this problem is to use elements of the RSA algorithm in fractal algorithmic transformations and their systems.
One of the ways to solve this problem is to use elements of the RSA algorithm in mathematical transformations, in particular, in fractal algorithmic transformations.
Fractal transformations can be both linear and quadratic. And also systems of such fractal transformations. Encryption – decryption can be performed both with additional noise and without additional noise.

This paper presents the comprehensive design and implementation of an RPD (Remote PHY Device) module, which serves as a pivotal component within the Remote PHY Node architecture for hybrid fiber-coaxial (HFC) networks based on the DOCSIS 4.0 standard. The development of this module addresses the critical need for enhanced data transmission rates and network efficiency in modern broadband communication systems. The research thoroughly investigates the integration of GCP/R-DEPI/R-UEPI protocols into the RPD module, utilizing advanced packet processing technologies to optimize data transfer between the CCAP (Converged Cable Access Platform) Core and the cable modem.
The proposed model is developed using open-source software, providing extensive flexibility for customization, adaptation, and enhancement in various HFC network applications. This approach also ensures that the model can be readily improved or expanded to meet the evolving demands of next-generation broadband networks. A key focus of the study is the architectural analysis of the Remote PHY Node, with particular emphasis on the interaction between the RPD module and the RF Module (RFM), and the critical interfaces that ensure seamless data transmission and network stability.
Through detailed experimentation and modeling, the study reveals that the incorporation of DPDK (Data Plane Development Kit) into the RPD module results in significant performance improvements. By bypassing the traditional kernel-based packet processing, DPDK reduces latency, increases throughput, and enhances the overall efficiency of network packet handling. The multi-level model developed in this research comprises context, container, component, and code levels, providing a structured and scalable framework for the RPD module's implementation.
Furthermore, the study demonstrates that the RPD module, when implemented according to the DOCSIS 4.0 standard, offers substantial improvements in network security, supports a distributed access architecture, and significantly boosts the processing efficiency of data packets. These advancements position the developed RPD module as a critical enabler of next-generation HFC networks. The paper concludes by outlining the potential for future research, particularly in exploring the scalability, robustness, and adaptability of this model in large-scale network deployments, as well as its integration with emerging technologies in the field of telecommunications.

No Smoking Class -kilpailu on järjestetty vuodesta 1989 alkaen kahdeksannen luokan oppilaille. Kilpailuun osallistuneen luokan oppilaiden piti sitoutua olemaan puoli vuotta tupakoimatta. Osallistuminen perustui vapaaehtoisuuteen. Niiden luokkien kesken, joissa oppilaat olivat olleet tupakoimatta puoli vuotta, arvottiin neljä 10 000 markan ja kymmenen 1000 markan palkintoa. Kilpailuun osallistui lukuvuonna 1991–1992 1160 luokkaa eli noin 22 000 oppilasta, mikä on noin kolmannes koko ikäluokasta. Kilpailun arvioimiseksi osallistuneista ja osallistumattomista luokista valittiin satunnaisesti 97 luokkaa (noin 1900 oppilasta). Näistä kilpailun loppuun selviytyneitä luokkia oli 28, keskeyttäneitä 39 ja osallistumattomia 30. Tutkimus suoritettiin kolmessa vaiheessa lomakekyselynä: ennen kilpailua, kuukausi kilpailun päättymisen jälkeen ja vuosi kilpailun päättymisen jälkeen. Oppilaat täyttivät kysymyslomakkeen oppitunnin alkaessa. Vastausprosentti oli 92. Tupakointi lisääntyi kilpailuun osallistuneissa luokissa 8. luokalla vähemmän kuin keskeyttäneissä tai kokonaan kilpailuun osallistumattomissa luokissa. Yhdeksännellä luokalla tupakointi yleistyi yhtä paljon kaikissa kouluryhmissä.
Siviilisäätyjen kuolleisuuserot

Eri aikoina erilaisissa yhteiskunnissa tehdyt tutkimukset osoittavat, että naimisissa olevien kuolleisuus on selvästi alhaisempi kuin muiden siviilisäätyryhmien. Suomessa siviilisäätyryhmien väliset kuolleisuuserot ovat suuremmat kuin esimerkiksi alueiden tai sosiaaliryhmien väliset erot. Avioliitossa elävien kuolleisuus on selvästi pienempi kuin muiden ryhmien. Kaikkein suurin kuolleisuus on eronneiden miesten ja naimattomien naisten keskuudessa. Erot ilmenevät kaikissa yleisimmissä kuolemansyyryhmissä ja ne johtunevat sekä terveyteen liittyvästä valikoitumisesta että avioliiton terveyttä edistävistä vaikutuksista. Eri syytekijöiden merkitystä ei kuitenkaan voida luotettavasti arvioida. Kahdenkymmenen viime vuoden aikana erot ovat nopeasti kasvaneet. Työikäisten suomalaisten kuolemista vähenettäisiin jo runsas kolmannes, jos muiden siviilisäätyjen kuolleisuus olisi yhtä pieni kuin naimisissa olevien. Tarvitaankin kipeästi tutkimustietoa tämän kansanterveyden kehityksen synkän piirteen syistä sekä korjaamismahdollisuuksista.

Artikkelissa esitetään katsaus sosiaaliluokan vaikutusta syöpäpotilaan eloonjäämiseen tarkasteleviin tutkimuksiin. Painopiste on Suomessa tehdyissä kolmessa tutkimuksessa.
Varhaisemmissa tutkimuksissa selvitettiin, onko sosiaaliluokkien välillä eroja eloonjäämisessä. Aiheesta on tehty runsaasti tutkimuksia eri maissa ja erilaisia syöpätyyppejä sairastavilla potilailla. Useimmissa tutkimuksissa ylempiin sosiaaliluokkiin kuuluvilla potilailla on havaittu parempi ennuste kuin muilla.
Uusimmissa tutkimuksissa keskitytään selvittämään niitä tekijöitä, jotka vaikuttavat sosiaaliluokkien välisten erojen syntyyn.
Lopuksi esitetään joitain tutkimussuuntia, joista on odotettavissa hyödyllistä lisätietoa.
Työ, psykososiaaliset tekijät ja terveyserot
Authors: Vuori Jukka
Published: January 2025

Työelämässä heijastuvat samansuuntaiset sosioekonomiset terveyserot kuin muuallakin yhteiskunnassa. Terveyseroista syntyvää kuvaa voidaan tarkentaa tarkastelemalla työelämässä vaikuttavia psykososiaalisia tekijöitä, jotka muuntelevat ympäristön vaikutuksia terveyteen. Suomalaisesta työelämästä tehdyn pitkittäistutkimuksen mukaan elämäänsä tyytyväisille ja itsensä toimintakykyisiksi kokeville on kasaantunut monia muitakin vahvuuksia ja etuja työelämässä, ja heidän psyykkiset ja sosiaaliset terveyden voimavaransa ovat muiden voimavaroja paremmat.
Nuoruudessa tutkitut psykososiaaliset tekijät ennustivat monella tavoin, mutta yleisesti melko heikosti, aikuisiän terveyttä ja hyvinvointia. Tulokset antavat suuntaa terveyden edistämiselle työelämässä, jossa tulevaisuuden kuva on koetun laman seurauksena uhkaava. Nykyisessä kehityksessä on vaarana yhteiskunnallisen eriarvoisuuden lisääntyminen ja terveyserojen kasvaminen.

Kuntien terveyden- ja vanhustenhuollon menot asukasta kohden vaihtelevat huomattavasti. Tässä tutkimuksessa arvioidaan, kuinka paljon terveyspolitiikan kannalta tärkeät rakenteelliset, taloudelliset ja toiminnan tehostamiseen liittyvät tekijät vaikuttavat kuntien ja terveyskeskuskuntayhtymien terveyden- ja vanhustenhuollon menoihin vuonna 1991. Näiden tekijöiden vaikutuksia arvioidaan tilastollisella mallilla, joka perustuu kaksivaiheiseen painotettuun regressioanalyysiin.Tulosten mukaan kuntien ja kuntayhtymien erot terveydenhuolto- ja vanhustenhuoltomenoissa johtuvat väestön ikärakenteesta, työkyvyttömyysasteesta, tulotasosta, valtionosuuden tasosta, terveyskeskusten ja vanhainkotien tuottavuudesta sekä palvelurakenteesta. Kuntien omilla tuottavuuden lisäämiseen ja palvelurakenteen muuttamiseen liittyvillä toimilla voidaan aikaansaada huomattavia säästöjä kuntien terveyden- ja vanhustenhuollon kustannuksissa.

Tämän tutkimuksen tarkoituksena oli selvittää, onko varhainen tupakointi tai aikaiset tupakointikokeilut yhteydessä 13- ja 14-vuotiaiden suun terveyteen ja kartoittaa tämänikäisten tupakointia. Tutkimuksen aineiston muodostivat kaikki vuonna 1979 syntyneet Kokkolan, Pietarsaaren, Seinäjoen ja Vaasan kaupungeista (N=2462). Vuosina 1992 ja 1993 heistä 99 % kävi hammaslääkärin tarkastuksessa, jota ennen kartoitettiin kyselylomakkeella tupakointiin liittyviä tietoja ja asenteita sekä tupakointia. Päivittäin tupakoivia oli 4,8 % oppilaista; tytöt 3,7 % ja pojat 5,6 %. Tupakointia oli kokeillut 41,7 %; tytöt 39,0 % ja pojat 50,3 %. Purutupakan kokeilu oli lähes neljä kertaa yleisempää säännöllisesti tupakoivien kuin tupakointia kokeilleiden keskuudessa, ja poikien purutupakan käyttö oli yleisempää kuin tyttöjen.Tupakoinnin terveyshaitoista tiesi 95 %:a tutkimukseen osallistuneista. Tupakoinnin olisi halunnut lopettaa 74 % ja sen lopettamista oli yrittänyt 63 % säännöllisesti tupakoivista. Vieroitusryhmään olisi ollut valmiita tulemaan joka viides säännöllisesti tupakoivista. Tupakoivien oppilaiden vanhempien tupakointi oli yli kaksi kertaa yleisempää kuin ei tupakointia kokeilleiden oppilaiden vanhempien. Tupakoivien poikien vanhemmista viidennes ja tyttöjen neljännes hyväksyi lapsensa tupakoinnin. Vanhempien tupakoimattomuus näyttäisi edesauttavan nuoren tupakoimattomuutta.Korkea DMF-indeksi sekä korkeat D- ja CPI-indeksit olivat yhteydessä purutupakan käyttöön ja säännölliseen tupakointiin.
