Cooperative learning and teamwork effectiveness: impacts of education period on cadets

Abstract Maritime industry is a multinational industry where participants of several languages and cultures operate in a global teamwork environment. Seafarers' operating procedures are totally based on a teamwork infrastructure and climate. By the introduction of Safety Management Systems, shore-based human resources are also included in the wider system of the maritime teamwork of the company where information and communication technologies have accelerated this integration. Goals and tasks for the team, team composition, team-player styles, phases of team development, communication and interpersonal skills, decision making, leadership, and evaluation of team performance are the key elements in developing the structure of the teamwork based systems. Training and development is the main instrument in preparing the human resources for the teamwork climate of modern organizations. Education methodologies that support the characteristics, which encourage teamwork and cooperation, are widely applied in maritime education. Cooperative learning and problem-based learning are among those approaches. This study analyzes the effects of cooperative learning dimensions among the cadets in a maritime higher education institute with regard to teamwork effectiveness. An empirical study has been realized to measure the effects of cooperative learning dimensions on 1) individual performance in groups, 2) effective team members. To comment on the impacts of the education period on these dimensions, the study aims to realize a comparative analysis among the cadets of a senior clas s, before and after a simulator based bridge team management course

Case Report Inguinal Hernia Containing Uterus, Fallopian Tube, and Ovary in a Premature Newborn

A female infant weighing 2,200 g was delivered at 34 weeks of gestation by vaginal delivery. She presented with an irreducible mass in the left inguinal region at 32 days of age. An ultrasonography (US) was performed and an incarcerated hernia containing uterus, fallopian tube, and ovary was diagnosed preoperatively. Surgery was performed through an inguinal approach; the uterus, fallopian tube, and ovary were found in the hernia sac. High ligation and an additional repair of the internal inguinal ring were performed. Patent processus vaginalis was found during contralateral exploration and also closed. The postoperative course was uneventful. After one year of follow-up, there have been no signs of recurrence

Solid pseudopapillary tumor of the pancreas: a rare entity

Solid pseudopapillary tumor (SPT) of the pancreas is a rare neoplasm in children that mainly occurs in young females. We herein report a rare case of SPT arising from the tail of the pancreas. A 13-year-old girl was admitted to our clinic with abdominal pain and anorexia. A mass was palpated on the physical examination. A 90x72 mm, encapsulated, heterogeneous mass with solid and cystic components was defined on computerized tomography (CT). Distal pancreatectomy was performed during the operation. Histopathological examination revealed that the tumor was a SPT with negative surgical margins. A six-month follow-up after surgical resection showed no evidence of recurrent disease. SPT should always be considered in the differential diagnosis in a young female with a palpable mass

Exploring the relationship between caffeine metabolism-related CYP1A2 rs762551 polymorphism and team sport athlete status and training adaptations

Background: This study aimed to achieve a dual objective: to compare the frequencies of CYP1A2 rs762551 genotypes between team sport athletes and a control group, and to determine the association between the rs762551 polymorphism and changes in physical performance after a six-week training program among elite basketball players. Methods: The study encompassed an analysis of 504 individuals, comprising 320 athletes and 184 controls. For the Turkish cohort, DNA was isolated using the buccal swab method, and genotyping was conducted using the KASP technique. Performance assessments included the Yo-Yo IR2 and 30 m sprint tests. For Russian participants, DNA samples were extracted from peripheral blood, a commercial kit was used for DNA extraction, and genotyping of the rs762551 polymorphism was conducted using DNA microarray. Result: Notably, a statistically significant linear decline in the prevalence of the CC genotype was observed with ascending levels of athletic achievement within team sports (sub-elite: 18.0%, elite: 8.2%, highly elite: 0%; p = 0.001). Additionally, the CA genotype was the most prevalent genotype in the highly elite group compared to controls (80.0% vs. 45.1%, p = 0.048). Furthermore, statistically significant improvements in Yo-Yo IR2 performance were noted exclusively among basketball players harboring the CA genotype (p = 0.048). Conclusions: The study’s findings indicate that the rs762551 CC genotype is a disadvantage in elite team sports, whereas the CA genotype provides an advantage in basketball performance

Recent advancements in the breeding of sorghum crop: current status and future strategies for marker-assisted breeding

Sorghum is emerging as a model crop for functional genetics and genomics of tropical grasses with abundant uses, including food, feed, and fuel, among others. It is currently the fifth most significant primary cereal crop. Crops are subjected to various biotic and abiotic stresses, which negatively impact on agricultural production. Developing high-yielding, disease-resistant, and climate-resilient cultivars can be achieved through marker-assisted breeding. Such selection has considerably reduced the time to market new crop varieties adapted to challenging conditions. In the recent years, extensive knowledge was gained about genetic markers. We are providing an overview of current advances in sorghum breeding initiatives, with a special focus on early breeders who may not be familiar with DNA markers. Advancements in molecular plant breeding, genetics, genomics selection, and genome editing have contributed to a thorough understanding of DNA markers, provided various proofs of the genetic variety accessible in crop plants, and have substantially enhanced plant breeding technologies. Marker-assisted selection has accelerated and precised the plant breeding process, empowering plant breeders all around the world
