Authors: Ferbia Tea Qaula
Published: December 2018

Perusahaan besar yang sukses saat ini tidak langsung memiliki system yang sudah tertata dengan baik. Pada awalnya perusahaan besar mengalami perkembangan dari system yang sederhana atau tradisional. Dari hanya sekedar menghitung keuntungan sampai dengan pelaporannya. Pada penelitian ini, akan mengambil contoh data dari perusahaan supermarket bangunan dan furniture yang dahulunya dalam awal perkembangan menggunakan metode konvensional atau perhitungan manual. Pembelian produk oleh perusahaan kepada supplier dan kemudian di jual atau didistribusikan kembali kepada customer secara langsung. Penentuan margin harga dimana pada margin harga itu harus sudah terpenuhi keuntungan. Dari konsep sederhana itu dikembangkanlah dengan system ERP yang lebih kompleks. ERP dalam makalah ini akan membahas dampak pengaruh penggunaan ERP pada perusahaan retail. Perusahaan ERP yang berkembang dari konsep toko menjadi supermarket. Dimana pembuatan proses-prosesnya dibagi dari perbagian (keuangan, pengadaan barang, gudang, marketing, bagian setor, dan marcendese development. Pada kasus ini akan dibahas mengenai keuangan dan merchandise development. Kedua laporan yang diperoleh dari Merchandise Development dan keuangan dapat diperoleh informasi perkembangan perusahaan. Perencanaan perkembangan perusahaan oleh direksi dapat didasarkan pada kedua laporan bagian tersebut tetapi disertai dengan laporan bagian-bagian lain yang tidak kalah pentingnya. Dengan demikian system ERP membuat proses bisnis perusahaan menjadi lebih efisien dan efektif.
ОБҐРУНТУВАННЯ ВТОРИННОГО ПЕРЕТВОРЮВАЧА СИСТЕМИ КОНТРОЛЮ ЕНЕРГОЕФЕКТИВНОСТІ КУЛЬОВОГО ПОДРІБНЕННЯ РУДИ ОПТИМІЗАЦІЄЮ, АНАЛІЗОМ, МОДЕЛЮВАННЯМ

Дана публікація присвячена обґрунтуванню вторинного перетворювача системи контролю енергоефективності руйнування руди безпосередньо в барабані кульового млина. Первинним перетворювачем тут є пружна пластина, а прогин її центральної частини в наслідок руйнування руди при ударах куль через передаточний елемент – вихідною величиною, яка може фіксуватися або за переміщенням, або за деформацією. Існує широке коло засобів для вимірювання таких параметрів. Тому методом оптимізації на першому етапі дослідження відкидалися засоби, які об’єктивно не придатні для реалізації цих функцій. З залишку кілька засобів було вилучено шляхом аналізу. Далі досліджувались магнітоіндукційний і тензометричний перетворювачі. Аналізом доведено, що тензометричний перетворювач може виконувати функції вимірювання сигналу. Магнітоіндукційний перетворювач досліджувався методом моделювання. Показано, що він, забезпечений перетворювачем Холла, може фіксувати такі переміщення точно і за лінійною залежністю. Магнітоіндукційний перетворювач з обмоткою може давати додаткову інформацію про швидкість переміщення пружної пластини при ударі кулі. Обидва перетворювачі потребують установки проміжного передаточного елемента. Магнітоіндукційний – для забезпечення переміщення рухомого елемента з магнітном’якого матеріалу в площині, паралельній немагнітній прокладці, а тензометричний – для забезпечення деформування невеликої балки з двома ідентичними перетворювачами для компенсації впливу температури і підвищення чутливості.

Обґрунтований метод моделювання та аналізу просторово-часової еволюції нелінійних поверхневих збуджень бетонної суміші, що ущільнюється, у вертикально вібруючому циліндричному баку при його ідеальному збудженні. У межах запропонованого методу й прийнятих припущень отримане стандартне нелінійне еволюційне рівняння у частинних похідних, яке дозволяє здійснювати детальний аналіз виникаючих нелінійних хвиле утворень у досліджуваній системі. У більшості випадків цим рівнянням є нелінійне рівняння Шредінгера з дисипацією. Проведений всебічний аналіз отриманих аналітичних розв’язків вказаного рівняння для випадків: а) вільного без демпфування руху бетонної суміші; б) вільного руху бетонної суміші з демпфуванням; в) квазісолітонного руху бетонної суміші в умовах компенсації демпфування і наявності привантаження на поверхні циліндричного бака. Знайдені аналітичні розв’язки нелінійного еволюційного рівняння періодичного типу (т.з. кноїдальні хвилі) описуються еліптичними функціями Якобі чи функціями Вейєрштрасса. Квазісолітонні розв’язки мають у своєму знаменнику типову функцію для солітонних (уособлених) хвиль – гіперболічний косинус, тобто пропорціональні гіперболічному секансу. Застосування привантаження спеціальної форми (радіально ребристої) при віброформуванні виробів з бетонної суміші дозволяє збуджувати квазісолітон на поверхні рідини/суміші, що ущільнюється, й чітко визначити всі фізичні константи (амплітуду, швидкість, початкову фазу коливань), які фігурують у розв’язку еволюційного рівняння, виникаючих квазісолітонних хвилеутворень. Результати даного дослідження можуть бути у подальшому використані для уточнення й вдосконалення існуючих інженерних методів розрахунку енергосилових характеристик вібромашин для ущільнення бетонних і будівельних сумішей як на стадіях їх проектування/конструювання, так і у режимах реальної експлуатації.

Growth and Yield Performance of Inbred and Hybrid Rice Varieties as Influenced by Combined Application of Organic and Inorganic Fertilizers
Authors: Baoy Raynilda , Bañoc Dionesio
Published: December 2018

The study evaluated the effects of organic and inorganic fertilizers on the growth and yield of two lowland rice varieties; determined the proper fertilizer combination; and evaluated the profitability of rice production as influenced by the combined application of organic and inorganic fertilizers. This was laid out in split plot arranged in a RCBD design with variety and fertilizer treatments as the main plot and subplot, respectively.
Results revealed that the period from sowing to heading, shoot dry weight, number of filled grains per panicle and weight of 1,000 grains were significantly influenced by the variety. The yield, yield components and harvest index (HI) were significantly influenced by fertilizer application. A significant interaction effect was noted on the period from sowing to heading as observed that inbred rice (NSIC Rc212) headed late than hybrid (TH82). Plants applied with 120-60-60 kg ha-1 N, P2O5 and K2O produced taller height, larger LAI, longer panicles, more productive tillers and filled grains, and consequently highest grain yield and HI. These plants also produced the heaviest root and shoot dry weights resulting to higher root shoot ratio compared to unfertilized plants. Highest net income was obtained in plants applied with inorganic fertilizer at the rate of 120-60-60 kg ha-1 N, P2O5 K2O due to high grain yield. Irrespective of fertilizer treatments, inbred rice was more profitable than hybrid. Highest production cost was incurred in plants applied with pure organic fertilizer due to the high cost of the material.
Lignin — a promising biomass resource
Authors: Qian Yong , Lou Hongming , Liu Weifeng , Yang Dongjie , Ouyang Xinping , Li Yuan , Qiu Xueqing
Published: December 2018

Lignin, the second most abundant component in plants, is a class of complex aromatic polymer. Industrial lignin is a major byproduct of pulp and paper production and biorefineries, with more than 50 megatons generated annually. However, more than 98% of industrial lignin is either burned as fuel or discharged as wastewater, causing serious environmental pollution. From a sustainable feedstock perspective, finding additional high-volume and high-value applications for lignin is an extremely important and long-term pursued objective. Thus, lignin resources deserve to be further exploited as biorenewable raw materials for energy-saving and lowcarbon polymer production. Inspired by the natural three-dimensional structure, excellent ultraviolet-blocking and antioxidant properties of lignins, the authors have focused their research on lignin-based biorenewable resources. This review summarizes research achievements of the recent decade. Progress has been made in several aspects, such as nonionic and amphoteric lignin-based surfactants, lignin-based functional materials, lignin-based photoelectric materials, lignin-based resins and polymer composites, and catalytic depolymerization of lignin.
Monitoring the free lime content in lime mud using zeta potential
Authors: Ren Wei , Tran Honghi
Published: December 2018

The presence of unreacted lime (free lime) in the lime mud can cause many problems in the chemical recovery operation of kraft pulp mills. There are currently no standards for free lime determination. Conventional methods used in mill laboratories require extensive preparations and give inconsistent and sometime erroneous results. A systematic study was performed to determine if zeta potential, a dispersion characteristic of the lime mud and liquor slurry, can be used to indirectly indicate the amount of free lime in the lime mud. Lime mud with different free lime contents was produced in the laboratory by causticizing green liquors with lime at different liming ratios. The results show that zeta potential changes from negative to positive when the free lime in lime mud exceeds a critical value. This unique characteristic enables a rapid detection of free lime.
Effect of ring formation on burner flame stability in lime kilns
Authors: Mohanan Girish , Tran Honghi , Bussman Markus , Manning Richard
Published: December 2018

Ring formation in lime kilns is a common problem in pulp mills. Unstable burner operation that causes wide temperature variations within the kiln has been shown to be a main contributor. As rings grow thicker and longer, they are expected to affect the burner flame pattern, alter the temperature distribution, and further aggravate the problem. This study systematically examines the effect of rings on burner operation as a function of primary air and ring characteristics, using a laboratory mock kiln. The results show that primary air greatly affects the burner flame pattern and stability. Without a ring, the flame is brighter and shorter, with an increase in primary air (PA) up to 17%, and blows out at 20% PA or higher. In the presence of a ring, the flame becomes unstable and blows out when the ring is placed near the burner, but it is more stable when the ring is placed away from the burner. Thick and long rings destabilize the flame more than thin and short rings.
Dry chip feedrate control using online chip moisture
Authors: Gilbert Wesley , Trush Ivan , Allison Bruce , Reimer Randy , Mason Howard
Published: December 2018

Normal practice in continuous digester operation is to set the production rate through the chip meter speed. This speed is seldom, if ever, adjusted except to change production, and most of the other digester inputs are ratioed to it. The inherent assumption is that constant chip meter speed equates to constant dry mass flow of chips. This is seldom, if ever, true. As a result, the actual production rate, effective alkali (EA)-to-wood and liquor-to-wood ratios may vary substantially from assumed values. This increases process variability and decreases profits. In this report, a new continuous digester production rate control strategy is developed that addresses this shortcoming. A new noncontacting near infrared–based chip moisture sensor is combined with the existing weightometer signal to estimate the actual dry chip mass feedrate entering the digester. The estimated feedrate is then used to implement a novel feedback control strategy that adjusts the chip meter speed to maintain the dry chip feedrate at the target value. The report details the results of applying the new measurements and control strategy to a dual vessel continuous digester.
Bem Viver: Projeto U-tópico e De-colonial

O presente artigo trata da concepção andina do “Bem Viver”, tradução das expressões Kechwa “Sumak Kawsay” e Aymara “Suma Qamaña”. Partindo dos sinais da atual crise civilizatória e ambiental provocada pelo capitalismo e seu suporte ideológico calcado no individualismo e no racionalismo, questiona-se a pretensa relação do “Bem Viver” com conceitos moderno-ocidentais como “desenvolvimento humano” e “qualidade de vida”, e defende-se o termo como expressão de uma utopia andina baseada numa cosmologia e filosofia próprias, e nos processos de resistência indígena à colonialidade do poder.
La Población Indígena Y El Cambio Climático En Centroamérica: Aproximaciones a Su Impacto
Authors: Camacho María Fernanda Morales , Soto- Acosta Willy
Published: December 2018

Nos últimos anos, popularizou-se a expressão migrantes ambientais, apesar de o conceito não ter sido, ainda, introduzido, na doutrina do direito internacional e, tampouco, ter havido o reconhecimento da categoria refugiado ambiental. Apesar destas lacunas, as alterações climáticas têm tido um impacto sobre as decisões, de povos mais vulneráveis, tanto para empreender uma migração interna quanto externa. Concretamente, a população indígena centro-americana representa um grupo de grande vulnerabilidade, dadas as condições sócio-econômicas e pelo fato de estarem, as comunidades, assentadas em áreas de grande risco no que diz respeitos a desastres naturais. Desta forma, eventos climáticos, tais como:furações, tormentas e secas contribuem para a exclusão destas minorias na região.
Influencia Interlingüística: Rasgos del Español en El Criollo limonense
Authors: Argüello René Zúñiga
Published: December 2018

Depois da chegada dos primeiros jamaicanos à Costa Rica em 1872, a língua crioula trazida pelos trabalhadores, isto é o crioulo jamaicano, desenvolveu características únicas e distintivas após de mais de 140 anos. Alguns desses câmbios consumaram-se durante os primeiros 75 anos; entretanto o câmbio abrupto na língua dominante do inglês ao espanhol a partir de 1949 causou uma transformação mais radical. O fim deste artigo é justamente a descrição de alguns desses câmbios na fonologia e a morfossintaxe, os quais vêm sendo muito diferentes daqueles da língua original e que até poderiam ser atribuídos à influência do novo superstrato. Os fenômenos são tratados no marco das novas investigações em matéria de contato linguístico ao níveo sistemático em vez do níveo individual (SIEMUND, 2008).
Protagonismo Juvenil, Pedagogia Social e o Pensamento Pedagógico Freireano: alguns desafios e perspectivas para a formação de educadores e educadoras sociais em projetos socioeducativos
Authors: Silva Alexandre Magno Tavares da
Published: December 2018

Este artigo discute algumas experiências e reflexões a partir do trabalho dos educadores e educadoras sociais que estão ativos em projetos sócio-educativos para cuidar de crianças, adolescentes e jovens em condições de pobreza no Nordeste brasileiro. Com base nas considerações de Paulo Freire, vamos nos concentrar no  Protagonismo Juvenil como categoria e prática social e educacional para discutir a posição deste conceito no processo de aprendizagem e de trabalho dos educadores e educadoras sociais que atuam em áreas não-escolares. Esta discussão aponta para a necessidade de concentrar uma série de experiências sociais e educativas e de abordar seu desdobramento nos países do Terceiro Mundo e seu impacto social, que - embora ricas em significado e potencial- correm o risco de permanecer despercebidas por parte da atenção acadêmica que não se dá conta dessas áreas como espaços de conhecimentoe desenvolvimento de competências. Se o protagonismo juvenil vem alterando os fundamentos teóricos e metodológicos da formação dos educadores sociais, e do trabalho social, certamente afetará e influenciará na ação pedagógica (teórico e metodologica) dos educadores e educadoras sociais. Isto deverá permitir uma experiência intercultural que pode vir a contribuir para criar uma sociedade justa e solidária.
O pensamento pedagógico de Paulo Freire à luz da filosofia da educação
Authors: Gonçalves José Luís A
Published: December 2018

Propomo-nos analisar neste artigo o pensamento pedagógico de Paulo Freire na ótica da filosofia da educação. Entendendo-se esta área de saber, simultaneamente, como reflexão tanto das problemáticas educacionais (no plano epistemológico e hermenêutico) como das problemáticas educativas (dimensão ética e antropológica) presentes no discurso pedagógico de Paulo Freire, a nossa análise assentará numa circularidade epistemo-antropológica deste pensamento. Dito de outra forma, é nossa intenção caracterizar a relação estreita que estabelecem entre si uma epistemologia da práxis e uma antropologia dialógica no pensamento pedagógico deste grande educador.

O presente estudo objetiva estabelecer um diálogo aproximativo entre a epistemologia dos saberes populares, os saberes tradicionais indígenas e a educação em Direitos Humanos. Nesse diálogo situamos as especificidades, os nuances e organização própria de cada modo aprendente/ensinante na tentativa de perceber o que há de latente nos conteúdos e perspectivas dos Direitos Humanos nas respectivas leituras de mundo e da palavra. Nessa compreensão, estabelecemos o diálogo entre essas leituras de mundo das tradições popular e indígena (indígenas de Pernambuco), evidenciando os valores axiológicos tradicionais, e o que eles anunciam e denunciam das formalidades ideologizadas acerca da declaração dos Direitos Humanos. Nessa direção, esse diálogo contribui com as possíveis revisões dos conteúdos e formas das vivências da educação em Direitos Humanos. Para tanto, servimo-nos da abordagem das Epistemologias do Sul, sobremaneira, das contribuições de Boaventura de Sousa Santos, Paulo Freire, Ivone Gebara, Saberes do Povo Kambiwá, Susana Sacavino e Ana Maria Rodino. Concluímos que esse diálogo muito enriquece não só as discussões da educação em Direitos Humanos, mas também amplia o exercício das leituras Interculturais na perspectiva ético-política. Saberes Populares.

Published: December 2018

Background: In malaria endemic areas diagnosis of severe malaria by microscopy and immunodiagnostic test is confounded by asymptomatic peripheral blood parasitemia. In such settings, retinal changes by ophthalmoscopy showed some diagnostic utility. Contribution of ophthalmoscopy in diagnosis of severe malaria in children is not well studied in Bangladesh. The aim of this study was to describe the retinal findings in children of cerebral and non-cerebral severe malaria by direct and indirect ophthalmoscope and relate their outcome and to determine the course of changes in the fundus.

Methodology: In this prospective observational study 130 consecutive children aged between 6 months to 12 years admitted with confirmed severe Plasmodium falciparum malaria in pediatrics ward of Chittagong Medical College Hospital, Chittagong, Bangladesh were assessed by both direct and indirect ophthalmoscopy during the period of April 2008 to March 2009.

Results: Out of 130 patients 80 children had cerebral malaria and of these 49 (61.2%) had some degree of retinopathy; 24 (48%) of 50 with non cerebral severe malaria had retinopathy. Predominant retinal changes were Retinal hemorrhage and Macular whitening each in 53 (40.77%) patients, followed by peripheral whitening, Vessels changes and papilloedema in 50 (38.46%), 40 (30.77%) and 14 (10.78%) patients respectively. With indirect ophthalmoscope as reference, direct ophthalmoscopy had a high sensitivity to detect macular whitening, and papilloedema but was less sensitive to detect peripheral whitening and vessel changes. Patients with retinopathy had more chance to had unfavorable outcome (Death) in comparison to the patients who had not {Odds ratio:1.09 (95% CI:1.017-1.167)}. Most of these retinal changes were transient and resolved gradually as clinical condition improved.

Conclusion:Features compatible with malarial retinopathy were commonly found in our children with severe malaria. Ophthalmoscopy is an important clinical tool to aid in diagnosis and prognosis in children. However, indirect ophthalmoscopy provides better information than direct ophthalmoscopy.

Dyslipidemia in Childhood Obesity: A Review
Authors: Rahman Shahana A , Hossain Monira , Begum Suraiya
Published: December 2018

Childhood obesity has become epidemic in developed as well as developing countries. Apart from genetic factors, changes of lifestyle like consumption of excess calorie rich food, lack of physical activity and increased screen time are major contributing factors for childhood obesity. Many co-morbid conditions like cardiovascular, metabolic, neurological, hepatic, pulmonary, orthopedic, and renal disorders are associated with childhood obesity. It has both immediate medical complications as well as long term health consequences in later life. The most hazardous consequences like the cardiovascular disorder occur due to early athrosclerotic process which is accelerated due to dyslipidemia. As a result dyslipidemia is an important etiologic factor for development of cardiovascular disease (CVD), which is a leading cause of death in adulthood throughout the world. As abnormal vascular changes begins in childhood, and as dyslipidemia is an significant risk factor for CVD, screening and treatment of dyslipidemia in obese children and adolescents are an important health issue to prevent development metabolic syndrome and its consequences.

Food Tourists' Travel Behavior and Well-Being Effects
Authors: Lohmann Martin , Femers Antonia
Published: December 2018

This empirical study aims to identify the segment of "food tourists" with a quantitative approach, using data on behavior, motives, and attitudes. It explores food tourists' holiday trip behavior and the effects of such vacations on indicators of well-being (e.g., recreation, health,
and others). The data stem from a quantitative survey in Germany as a representative source market study ("Reiseanalyse 2015"), based on a nationwide random sample of N = 7,720 face-to-face interviews, with n = 5,996 holiday travelers, and n = 1,511 food tourists. Thus,
the data analysis is based on a post hoc segmentation with respect to who a food tourist is and who is not. The results allow determining the size of the food tourism segment with German tourists and the description of demographic characteristics as well as specific vacation behavior patterns.
In addition, food tourists show notable positive vacation effects, such as recreation, significantly above the average. As a statistical investigation (three-way between-subjects ANOVA) reveals, these impacts of a food holiday are not only driven by the culinary experience but also are strongly
based on personal attitudes and motives, showing the importance of in-person factors on the consumption experience of tourists. Implications are outlined for consumer research in tourism and marketing.

Risk assessment in large organizations with extensive operational domains has been a challenging issue. Employing an efficient method along with realistic pair comparisons, applying subjective inferences of organization experts, and purging the intrinsic ambiguity of inferences, are not reflected in current airlines' safety management. Traditional two-dimensional risk assessment for risk management of safety hazards, however, is no longer sufficient to comply with this complexity. A new model for risk management and a novel formula for risk index calculation, based on a fuzzy approach, are presented in this study.

In this new model, unlike in the traditional approach, the latent aftermath of safety reports, especially those which affect the continuity of the business, is also taken into account. In this model, along with the definition of a new structure for risk management, risk analysis should be restructured. To that end, a two-dimensional classic risk formula was replaced with three-dimensional (nonlinear) exponential ones, considering “the impact on the business” as a source of risk and hazard. For measuring the safety risk using the Fuzzy hierarchical evaluation method, considering experts' opinions, three criteria in four different operational fields were developed.

This method employs a Fuzzy ANP to help quantify judgments, make qualitative judgments in the traditional method, and weigh the priority of elements contributing to risk. Also, it provides a tool for top-level as well as expert level management to monitor safety more precisely, monitor the safety level within their departments or organizations, set quantitative safety goals and provide feedback for improvement as well as find the most critical areas with the least cost. In this study, an airline has been selected as a case study for the risk assessment of reports based on the new model.

Published: December 2018

This paper presents the results of the investigation of the residual tropospheric error influence on coordinate determination in a GNSS landing system. The ICAO recommended methodology for residual tropospheric error calculation is taken as a basis for the present research. Special attention is paid to the troposphere refractivity index and troposphere scale height, which are derived from the well-known troposphere refraction MOPS model. A computer simulation is performed for them for the whole year and the northern hemisphere latitudes. Hardware in the loop simulation has been performed to complement the computer simulation study and investigate the situation with the residual tropospheric error calculation for the experimental GNSS satellites configuration. The experimental measurement session with a duration of about 9 hours is recorded to obtain the configuration of real navigation satellites The residual tropospheric error in meters is calculated for each navigation satellite visible during the experiment. The authors investigate the residual tropospheric error influence on the accuracy of the coordinates determined in the GNSS landing system.

Published: December 2018

The purpose of the work was to optimize the parameters of the spillage system equipped with a gas pressure hydroaccumulator for a ship pressurized water reactor in a loss-of-coolant accident. The water-gas ratio in the hydroaccumulator and the hydraulic resistance of the path between the hydroaccumulator and the reactor were optimized at the designed hydroaccumulator geometric volume.

The main dynamic processes were described using a mathematical model and a computational analysis. A series of numerical calculations were realized to simulate the behavior dynamics of the coolant level in the reactor during the accident – by varying the optimized parameters. Estimates of the minimum and maximum values of the coolant level were obtained: depending on the initial water-gas ratio in the hydroaccumulator at different diameters of the flow restrictor on the path between the hydroaccumulator and the reactor. These results were obtained subject to the restrictive conditions that, during spillage, the coolant level should remain above the core and below the blowdown nozzle. The first condition implies that the core is in safe state, the second excludes the coolant water blowdown. The optimization goal was to achieve the maximum time interval in which these conditions would be satisfied simultaneously.

The authors propose methods for selecting the optimal spillage system parameters; these methods provide the maximum time for the core to be in a safe state during a loss-of-coolant accident at the designed hydroaccumulator volume. Using these methods, it is also possible to make assessments from the early stages of designing reactor plants.

Mednarodna primerjava dejavnikov vpliva na zgodnje opuščanje izobraževanja
Authors: Makovec Danijela
Published: December 2018

V članku razpravljamo o dejavnikih, ki vplivajo na zgodnje opuščanje šolanja, in o ukrepih, ki so bili v Sloveniji sprejeti, da bi slednje preprečili. Zmanjšanje zgodnjega opuščanja šolanja na manj kot 10 % do leta 2020 je namreč eden ključnih ciljev strategije Evropa 2020, Slovenija pa omenjeni cilj že presega. Po zadnjih raziskavah ima namreč naša država eno izmed najnižjih stopenj zgodnjega opuščanja šolanja med državami Evropske unije (EU). V prispevku proučujemo razloge za omenjeno nizko stopnjo zgodnjega opuščanja šolanja ter podajamo pregled institucionalnih in političnih ukrepov, ki jih je Slovenija sprejela, da bi zmanjšala osip in mladostnike čim dlje zadržala v izobraževalnem sistemu. Rezultati študije kažejo, da je v državah EU delež moških, ki so opustili šolanje, večji od deleža žensk ter da obstaja pozitivna povezanost med dejavniki, kot sta izobrazba staršev in socialno-ekonomski status družine, ter zgodnjim opuščanjem šolanja. Prav tako smo ugotovili, da je delež mladih priseljencev, ki so opustili šolanje, dvakrat večji od deleža mladih, ki živijo v državi, v kateri so se tudi rodili.
Over The Edge: Factors Nudging Mid-Career, School-Based Agriculture Teachers Out of the Profession

Published: December 2018

The field of agricultural education has experienced a consistent labor shortage the past several decades. Consequently, many school districts struggle to fill their open positions, while others are forced to shut down their agricultural programs completely due to inadequate staffing. Teacher attrition has been identified as a predominant factor behind the teacher shortage. The purpose of this mixed-methods study was to identify factors influencing mid-career school-based agriculture teachers’ decision to stay in or leave the secondary agriculture teaching profession. Researchers developed and administered questionnaires, as well as conducted interviews, to gather data from current, mid-career agriculture teachers to answer the research questions. The researcher’s discovered mid-career agriculture teachers are satisfied with their careers and significant differences do not exist in overall job satisfaction between those contemplating leaving and those who were not. However, differences existed between groups in areas related to recognition and school policy and administration. Additional findings suggest mid-career agriculture teachers value student and program successes, autonomy and variety, and stakeholder support. Moreover, the researcher’s discovered mid-career agriculture teachers experience similar frustrations as teachers in other professional life stages; however, they seem to struggle more with balancing their personal and professional lives due to changing family dynamics.

Agricultural mechanics instruction includes a broad array of machinery, structures, and technical systems, as well as a diverse workforce. Virtually every aspect of agriculture has a mechanics component and a large portion of secondary agriscience curriculum is devoted specifically to teaching agricultural mechanics. Further, the agricultural mechanics laboratory provides students with an opportunity to learn through authentic learning scenarios. The purpose of this research is to investigate Missouri high school agricultural mechanics students’ safety knowledge and safety attitudes. Researchers identified an increase in female students enrolling in agricultural mechanics coursework. This study also concludes students perceive they receive minimal training, access, and/or use of hearing and air quality PPE. It was concluded the factors of age, gender, semesters of agricultural mechanics courses, and agricultural education district have limited ability to explain differences in in student’s PPE knowledge or PPE comfort. Moreover, researchers identified implications of changing demographics on PPE design and usability, both in the laboratory and the workplace. Future research should be conducted regarding regarding PPE design, transfer of perceptions, and what PPE is needed by both teachers and students.
Science in the Garden: A Qualitative Analysis of School-based Agricultural Educators’ Strategies
Authors: Cross Sarah M. , Kahn Sami
Published: December 2018

Scholars in science education have reported an in increase in scientific literacy due to socioscientific issues (SSI)-based instruction. While several SSI are related to agriculture, such as climate change, whether to eat organic food, land use issues, and the use of genetically modified organisms (GMOs), literature that connects agricultural education to the theoretical framework is scant. This collective case study investigates how National Future Farmers of America (FFA) Organization teachers utilize school gardens to teach science, including whether and how SSI are utilized as an educational framework. Qualitative data was collected by conducting semistructured interviews with two Ohio school-based agricultural educators, and data was analyzed using the constant comparative method. Findings indicated both teachers utilized applied science teaching methods and expressed frustrations regarding the difficulty of meeting mandated science learning standards. While the teachers often integrated controversial topics in classroom discussions, fidelity to the SSI framework did not appear to be utilized.

Published: December 2018

The student teaching practicum experience is designed to give preservice teachers practical experience with teaching and is an important step in their development. While literature in agricultural education exists about preservice teacher professional development, little is known about the developmental process of agriculture teachers during the student teaching experience. Utilizing the theory of teacher concerns (Fuller & Brown, 1975) as a theoretical lens, the purpose of this qualitative document analysis was to determine how preservice teachers develop over the first half of the student teaching practicum by examining the way they talk about concerns. Written reflections of five different cohorts from 2010 through 2014 were analyzed at two different points in time (week two and week seven). During the first two weeks of student teaching, three themes emerged, including: 1) teacher/student identity crisis, 2) teaching competence: “I do not know how, what, or who…,” and 3) adjusting to change. During week seven, the concerns changed, which indicated the student teachers were developing into the professional role of a teacher. The three themes that emerged from the data for week seven were: 1) building professional relationships, 2) engaging students, and 3) it is about time: work-life balance. Implications exist for teacher educators to place more emphasis on teaching strategies to engage and motivate students in the learning process, rather than just the task itself. Recommendations are suggested for teacher educators to discuss with preservice teachers before student teaching the realities and challenges of balancing work and life roles.
Can they Relate? Teaching Undergraduate Students about Agricultural and Natural Resource Issues
Authors: Lamm Alexa J. , Harsh Jessica , Meyers Courtney , Telg Ricky W.
Published: December 2018

Undergraduate students should be able to identify relationships between agricultural and natural resources (ANR) issues to be prepared for ANR sector jobs. The purpose of this study was to determine if communication courses focused on teaching about ANR issues influenced students’ understanding of the relational nature of these issues. A pre/posttest research design was given to undergraduate students enrolled in communication courses at three universities that addressed communicating about nine ANR issues. After descriptive analysis, the data was visualized and density was calculated using social network analysis software. Prior to the course, the strongest perceived relationship was between food safety and food security, followed by water and animal health. After the course, the strongest perceived relationship was between water and food security, followed closely by water and conservation. Visually, water was central to the network of issues, followed by food security, and conservation. The density of the perceived interconnectedness of the issues indicated the respondents did perceive the nine ANR issues were more closely related after taking the course than before. In this case, courses focused on communicating about ANR issues assisted students in being able to convey how these issues are interdependent, preparing them for the workforce.
