Atypical carcinoid in the anterior mediastinum is a rare neoplasm. In our case the huge mediastinal carcinoid was treated with surgery using a median sternotomy and clamshell incision because of the extension of the tumor. We describe our difficulties under the surgery and take a look at the literature.

This paper presents analyses of observational and interview data gathered in a study of exemplary fourth-grade teachers from five states. The central issue explored is the relative merits of self-contained and departmentalized models of instruction. We found no achievement differences in the classrooms by organizational pattern, but differences in the instruction offered in these two models were identified, and mixed views of the relative advantages of either organization plan were expressed by the participants. A key tension was whether these organizational plans are intended to primarily benefit teachers or students. However, the complexities of the cost/benefit concerns are the findings that this study highlights.

The purpose of this study was to examine the influence of teacher-students’ interaction on motivation to learn mathematics among high school students. The study was guided by Keller ARCS model of motivation. Descriptive research design was employed in the study. The target population was all 8357 Form Four students from 113 public high schools in Laikipia County. Simple random sampling was used to select sample schools, sample classes and respondents. The sample consisted of 392 mathematics students who participated in this study. A self-administered questionnaire was used in data collection. Cronbach’s alpha was used in estimating the reliability coefficients of research instruments which were acceptable and above 0.7. Data was analyzed using simple regression analysis.The finding showed that teacher-students’ interaction has a significant influence on motivation to learn mathematics. The study concludes that in order to improve effectiveness of teaching and learning, teachers need to use the relevant classroom interaction practices wisely so as to guide and monitor students in the learning process for better motivation so as to enhance acquisition of knowledge.

The objective of the research was to determine the effects of the “Body Workout” aerobic exercises on morphological characteristics of female university students after a period of 2 months with training sessions in the duration of three hours per week. The sample of research participants was made up of female university students from the Faculty of Sports and Physical Education in Novi Sad (AGE = 22.13±0.98 years) that were actively included in the workout program. The total sample participating in the research comprised of 52 participants, 25 of which comprised the experimental group (AGE=22.11±0.89; TV=166.11±5.01) while the remaining 27 of them comprised the control group (AGE=22.45±0.78 years, TV=169.51±5.04). The experimental group followed the “Body Workout” aerobic exercises model and the control group followed the regular curriculum for the university course of Fitness (Rekreacija in Serbian) at the Faculty of Sports and Physical Education in Novi Sad. At the initial measuring, there were no statistically significant differences among the participants (P=0.41). Physical changes that occurred in the participants’ bodies during the research period of two months were followed by means of monitoring of twelve morphological characteristics. According to the research results, significant effects were determined in transformation of morphological characteristics among the members of the experimental group on the level of the entire system (P=0.00) and the individual differences could be perceived in the final measuring in variables Circumference of the lower leg (p=0.05), Skinfold of biceps brachii (p=0.00), Skinfold of triceps brachii (p=0.00), Skinfold of the forearm (p=0.00), Subscapula skinfold (p=0.02) and Abdominal skinfold (p=0.00) among the members of the experimental group. That is an indication that the experimental Body Workout program had a significant impact on the above mentioned characteristics. At the same time, it was determined that the experimental program of aerobic exercises produced the greatest effects on…

This study tested the relationship between Rwanda’s economic growth, foreign direct investment, and labor in agricultural spanning between 1970 and 2017. In this paper, the ARDL “bounds” test method is used to analyze the co-integration problem of variables with a constant level relationship. Co-integration coefficients were estimated using the ARDLs model. After verifying the long-term (co-integration) equilibrium relationship of economic growth within the variables, the error correction model is used to estimate the short-term coefficients. We found that agriculture and foreign direct investment have becomes an engine depending of Rwanda’s economic development. The FDI has a causal relationship to economic growth; while labor have no causal relationship to economic growth. The Rwandan government should promote macroeconomic policies to encourage foreign direct investment and promote economic growth in agriculture.

The examination and exploration for the nature and meanings of Modernity have been recently presented in philosophy, sociology and psychology books and journal articles. This article presents some of the important ideas in these disciplines and provides a perspective that integrates three disciplines (Philosophy, Sociology, and Psychology) and five authors’ views on Modernity (Charles Taylor, Jaan Valsiner, Anthony Giddens, Herbert Hermans, and Hartman Rosa). The paper first presents an overview of these authors. It goes on to illustrate several common themes of their work: 1) the role of narrative and a semiotic perspective as tools for understanding modernity, 2) a developmental orientation and exploration of how self and society might be seen as developmental processes, and 3) a beginning of a reorienting of philosophy, sociology and psychology as interconnected disciplines. The goal of presenting the views of these authors is to gain a perspective on why it is valuable to understand the historical period we live in (modernity), the roles played by narrative and semiotics and the developmental nature of humans and their culture, and how listening to the melody and tone of modernity aids in understanding modernity.

Field tests are necessary in establishing navigation models and algorithms for agricultural vehicle robots. And it costs much to use tractors or combine harvesters as the platform in terms of system modification, routine maintenance and fuel consumption. The objective of this research was to develop a general-purpose test platform for conducting experiments in agricultural autonomous navigation at a low cost based on a commercially available electric vehicle. A brushless motor was utilized as the power source for automatic steering. An analog PID controller was designed to compare steering commands and actual steering angle and calculate an appropriate voltage signal as the input of the motor driver. A rotary encoder was attached to the driving wheel and a digital PID controller was implemented to determine the throttle value in real-time in maintaining the test platform at a desired speed. A CAN-bus network was established to integrate the automatic steering system and the speed control system as two nodes for information communication. And a CAN node interface was reserved for receiving commands from autonomous navigation systems to be evaluated. Field tests showed that RMS errors were 2.6 cm and 0.054 m·s-1 for lateral offset and speed control, respectively, in tracking straight paths, which indicated that the newly developed test platform met requirements for agricultural navigation experiments.

Agriculture in the north of Côte d’Ivoire, like the rest of the country, is undergoing genuine development. This situation is leading producers to adopt new cultivation techniques, including the use of herbicides for weed control. Herbicides have advantages and disadvantages in their handling. Knowing how dangerous these products can be, identifying them would be advantageous, hence this study. The main objective of this study is to establish a list of herbicides used on vegetable and food crops in the study area. In the departments of Boundiali, Ferké, Korhogo, and Séguéla directed interviews were conducted with traders, producers, and firms. They focused on the active ingredients of the herbicides, the type, and the mode of use. At the end of the study, seventy-seven herbicides divided into twenty-two active ingredients were identified. Glyphosate was the most present followed by nicosulfuron. To conclude, it should be noted that herbicides are present in the habits of the producers in our study area. They still do not use the products according to the standards. These results will help improve the quality and sustainability of agriculture.

Objectives: Legacy allows individuals to make meaning of their lives by passing on their experiences and beliefs to younger people and influencing their perspectives, perceptions, and actions. This mixed-methods study investigated: (1) What is important for older adults to share as legacy with families, friends and others, based on the types and features of their digital stories ? and (2) How do older adults’ digital stories affect story viewers? Methods: One hundred adults aged between 55 and 95 years participated in ten-week Elder’s Digital Storytelling courses and created short digital stories. Using the content analysis approach, the story transcripts were thematically analyzed and iteratively coded by three researchers and the results were quantified. A diverse group of 60 viewers at a public event provided their reactions to the digital stories. Results: The findings revealed that character, place, and family were chosen as the primary types by the older adults for their legacy digital stories. Accomplishment and career/school were the next most prominent story types. Moreover, these digital stories appeared to have a powerful impact on the viewers. Discussion: A digital story is a powerful artifact to communicate an older person’s legacy because it is based on familiar forms of communication, such as speech and photographs. The major legacy themes chosen by the older adults align with the findings of the research literature. The feedback from the viewers of the digital stories reflects these as a source of life wisdom and legacy for younger generations. Funding details: This work was supported by the AGE-WELL National Centre of Excellence (AW CRP 2015-WP4.3).
