Okvir za istraživanje nastave programiranja u srednjoškolskom obrazovanju
This study extensively reviews the literature on teaching programming to middle schoolers, with a qualitative content analysis method, and intends to put forth a research design framework for researchers that will guide them in the processes of planning and designing their research on teaching programming for middle school learners. For access to the relevant literature; the databases were searched by using the following keywords: “computer”, “programming”, and “middle school” together, limiting the findings to the articles published after 2000. As a result, an upward tendency was noted in studies about the teaching of programming at secondary level considering years, most of which are comprised of empirical ones. Also, the existing studies were mostly carried out with 6th graders predominantly employing data collection tools of questionnaires/scales and achievement tests. As for programming tools, Scratch was seen to be the most commonly used one. Although quite a few articles are investigating the context of the programming teaching lesson, some of the studies were found to use programming as a means of teaching mathematics, natural sciences, languages, writing skills, and social sciences. In conclusion, the present study is expected to pave the way for future research by highlighting the overall situation of programming teachingOvo istraživanje naširoko razmatra literaturu o nastavi programiranja u srednjim školama pomoću metode kvalitativne analize sadržaja i pretpostavlja se da će istraživačima ponuditi okvir za dizajniranje istraživanja koji će ih voditi u procesima planiranja i projektiranja njihovih istraživanja o nastavi programiranja u srednjoj školi. Za potrebe pristupa relevantnoj literaturi, pretražili smo baze podataka pomoću ključnih riječi „računalo” , „programiranje” i „srednja škola” uzetih zajedno, ograničavajući rezultate na članke objavljene nakon 2000. godine. Kao rezultat toga, primijetili smo porast trendova u istraživanjima o nastavi programiranja na srednjoškolskoj razini, uzimajući u obzir godine, od kojih je većina istraživanja empirijske naravi. Osim toga, postojeća su istraživanja uglavnom provedene s učenicima šestih razreda koji pretežno koriste alate za prikupljanje podataka u obliku upitnika/ljestvica i testova postignuća. Što se tiče alata za programiranje, Scratch je najčešće korišten. Iako postoji dosta članaka koji istražuju kontekst nastave programiranja, otkriveno je da neka istraživanja navode programiranje kao pomoćno sredstvo u učenju matematike, prirodnih znanosti, jezika, vještina pisanja i društvenih znanosti. Zaključno, valja napomenuti da se očekuje da će sadašnje istraživanje otvoriti put budućim istraživanjima, rasvjetljavajući cjelokupnu situaciju nastave programiranja
Nonomuraea basaltis sp. nov., a siderophore-producing actinobacteria isolated from surface soil of basaltic parent material
A Gram-stain-positive, aerobic, spore-forming actinobacterial strain, designated 160415(T), was isolated from a surface soil sample, which was formed on basaltic parent material, collected from Samsun, Turkey. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain 160415(T) clustered closely with species of the genus Nonomuraea, and showed the highest sequence similarity to Nonomuraea zeae NEAU-ND5(T), Nonomuraea candida HMC10(T) and Nonomuraea turkmeniaca DSM 43926(T) with 99.1%, 98.9% and 98.7%, respectively. Chemotaxonomic properties including major menaquinones, diaminopimelic acid, sugar and phospholipid profiles also confirmed the affiliation of the strain to the genus Nonomuraea. The DNA G+C content of strain 160415(T) was 69.6 mol%. DNA-DNA hybridization and average nucleotide identity values between the strain and closely related type strains were less than the recommended cut-off values. On the basis of phylogenetic relationships, genotypic and phenotypic characterizations, strain 160415(T) represents a novel species of the genus Nonomuraea, for which the name Nonomuraea basaltis sp. nov. is proposed. The type strain is 160415(T) (= KCTC 39875(T) = DSM 104309(T))

A Comparative Study on the VR Experience of Students in a Digital Documentary Game
VR technologies, which are used in many fields today, have also started to be used in education through the game platforms with the realistic and interactive environments they provide. The 'Following the Traces of Sedad Hakkı Eldem in Istanbul project, developed within the scope of a scientific project jointly carried out by the Architecture and Digital Game Design Departments at the host university, is an architecture-themed documentary game designed for educational purposes. Within the game's scope, three different projects of architect Sedad Hakkı Eldem, whose name is frequently mentioned in the history of the Early Republic period and in the modernization processes, were selected. The game's scenario was developed to perceive these architectural spaces by experience. However, this experience may vary according to the different department users due to their focal points and educational structures. According to this, this study conducted a research with the students at the host university to see how this documentary game was perceived and evaluated by students from two different departments. In order to conduct a comparative research, a questionnaire was directed to the students after their game experience. Especially the results of the third part proved the differences in the students' perceptions of different departments. On the other hand, although students from these two departments revealed some differences in their focus and approach to evaluating the game, the results also showed that the game provided an overall beneficial educational experience
Programlama Öğretimi için Bir Model Önerisi: Yedi Adımda Programlama
There are a number of studies in the literature revealing that programming instruction has positive effects on development of different cognitive skills. However, there are scarcely any studies suggesting pedagogical approaches to how programming should be done. Therefore, this study focused on how to do programming instruction that target developing students’ cognitive skills. In this study, it was aimed to suggest a model for teaching in order to develop various cognitive skills of students. Within the scope of the study, a programming instruction model was created, and it was called Programming in Seven Steps (PSS) model. As research design, special case study was used from qualitative research methods. The research team consisted of two groups: design team (1 faculty member from the department of Computer Education and Intructional Technologies (CEIT), 2 master’s degree students, and 2 PhD students) and a Design Evaluation Team (DET) (10 IT and Software teachers who work in secondary schools affiliated to the Ministry of National Education) in the process of constructing the PSS model. During the research, the documents and interviews with the design evaluation team were analyzed with the purpose of determining the steps of the PSS model. The study elaborates the process followed to create the model, the features of the proposed model, and interviews with the design evaluation team. This article details the overall path to designing of the model, the features of the model, and DET interviews. It is aimed that the model introduced in this study will become a guide for educators who want to teach programming at secondary school level.Alanyazında programlama öğretiminin pek çok bilişsel beceriye olumlu etkilerini ortaya koyan çalışmalar yer almaktadır.

First-line treatment of patients with HER2-positive metastatic gastric and gastroesophageal junction cancer
Fluoropyrimidine+cisplatin/oxaliplatin+trastuzumab therapy is recommended for the first-line treatment of HER2-positive metastatic gastric adenocarcinoma. However, there is no comprehensive study on which platinum-based treatment should be preferred. This study aimed to compare the treatment response and survival characteristics of patients with HER2-positive metastatic gastric or gastroesophageal junction (GEJ) cancer who received fluorouracil, oxaliplatin, and leucovorin (mFOLFOX)+trastuzumab or cisplatin and fluorouracil (CF)+trastuzumab as first-line therapy. It was a multicenter, retrospective study of the Turkish Oncology Group, which included 243 patients from 21 oncology centers. There were 113 patients in the mFOLFOX+trastuzumab arm and 130 patients in the CF+trastuzumab arm. The median age was 62 years in the mFOLFOX+trastuzumab arm and 61 years in the CF+trastuzumab arm (P = 0.495). 81.4% of patients in the mFOLFOX+trastuzumab arm and 83.1% in the CF+trastuzumab arm had gastric tumor localization (P = 0.735). The median progression-free survival (PFS) was significantly higher in the mFOLFOX+trastuzumab arm (9.4 months vs. 7.3 months, P = 0.024). The median overall survival (OS) was similar in both groups (18.4 months vs. 15.1 months, P = 0.640). Maintenance trastuzumab was continued after chemotherapy in 101 patients. In this subgroup, the median OS was 23.3 months and the median PFS was 13.3 months. In conclusion, mFOLFOX+trastuzumab is similar to CF+trastuzumab in terms of the median OS, but it is more effective in terms of the median PFS in the first-line treatment of HER2-positive metastatic gastric and GEJ cancer. The choice of treatment should be made by considering the prominent toxicity findings of the chemotherapy regimens
The frequency of Duchenne muscular dystrophy/Becker muscular dystrophy and Pompe disease in children with isolated transaminase elevation: results from the observational VICTORIA study
IntroductionElevated transaminases and/or creatine phosphokinase can indicate underlying muscle disease. Therefore, this study aims to determine the frequency of Duchenne muscular dystrophy/Becker muscular dystrophy (DMD/BMD) in male children and Pompe disease (PD) in male and female children with isolated hypertransaminasemia.MethodsThis multi-center, prospective study enrolled patients aged 3–216 months with serum alanine transaminase (ALT) and/or aspartate transaminase (AST) levels >2× the upper limit of normal (ULN) for ≥3 months. Patients with a known history of liver or muscle disease or physical examination findings suggestive of liver disease were excluded. Patients were screened for creatinine phosphokinase (CPK) levels, and molecular genetic tests for DMD/BMD in male patients and enzyme analysis for PD in male and female patients with elevated CPK levels were performed. Genetic analyses confirmed PD. Demographic, clinical, and laboratory characteristics of the patients were analyzed.ResultsOverall, 589 patients [66.8% male, mean age of 63.4 months (standard deviation: 60.5)] were included. In total, 251 patients (188 male and 63 female) had CPK levels above the ULN. Of the patients assessed, 47% (85/182) of male patients were diagnosed with DMD/BMD and 1% (3/228) of male and female patients were diagnosed with PD. The median ALT, AST, and CPK levels were statistically significantly higher, and the questioned neurological symptoms and previously unnoticed examination findings were more common in DMD/BMD patients than those without DMD/BMD or PD (p < 0.001).DiscussionQuestioning neurological symptoms, conducting a complete physical examination, and testing for CPK levels in patients with isolated hypertransaminasemia will prevent costly and time-consuming investigations for liver diseases and will lead to the diagnosis of occult neuromuscular diseases.
