ABSTRACTStress can be perceived as a response to threats situations (either physical or psychological) caused by individual inability  to overcome existing threats within his/her environment. Job stress is the result of interaction between an individual (i.e. a worker) and his/her occupation. The objective of this study to identify the factor affecting tojob stress by the divers at PT. X. This study applied cross-sectional design conducted by observing the divers at PT. X. The population of this study was all divers working at PT. X. Data was analyzed by Spearman Correlation Test, Pearson Correlation Test, and Chi-square Test. The results of this study is strong correlation between personality type and job stress (as indicated by correlation coefficient 0.645). The divers’ age (correlation coefficient -0.283), educational level (correlation coefficient -0.220), years of service/experience (correlation coefficient -0.158), length of diving session (correlation coefficient 0.083), and threats of marine animal attack (correlation coefficient 0.156) had lower correlation with job stress. While the divers residence might also affect their job stress (as indicated by correlation coefficient 0.539).Keywords: job stress, diver

The purpose of this study is to identify level and patterns of metacognitive awareness among teachers in primary schools. This study focuses on aspects of declarative knowledge, procedural knowledge, conditional knowledge, planning, monitoring and evaluation of teachers. The study was descriptive in nature. A sample of 100 primary school teachers in Puchong, Selangor answered the Metacognitive Awareness Inventory for Teacher by Cem Balcikanli (2011). The data analysis was carried out using IBM Statistics version 24 to obtain descriptive measures. The results show that levels of metacognitive awareness among teachers are high at ninety three percent (93%). The results also show that there are no significant differences by gender, age, teaching experience, academic qualification and subject of teaching among primary school teachers. The metacognitive framework shows that metacognition knowledge and regulatory expertise were used by individuals to control their cognition. Teachers who have a higher level of metacognitive awareness can produce students with good academic achievement.

Metacognition is the students’ ability in learning that includes about how learning should be done, so that it can determine what already known and not known yet. Metacognition has two components: metacognitive knowledge and metacognitive skills. Metacognitive knowledge relates to declarative knowledge, procedural knowledge, and conditional knowledge. Metacognitive skills relate to planning, monitoring, and evaluation towards the completion of a particular task. Metacognition has three stages: (1) planning about what, how, and when to learn it; (2) monitoring of learning process that being carried out; and (3) evaluating of what has been planned, done, and the results of that process. Metacognition of students in mathematics learning can be arisen at every stage of mathematical problem solving: understanding the problem, devising a plan, carrying out the plan, and looking back.

Introduction: In the Russian Federation, much attention is traditionally paid to military education and training. A special place in its structure is occupied by the system of cadet classes and corps. A distinctive feature of the learning mode in such institutions is a combined effect of standard and specific factors of indoor school environment and intensive physical activity owing to sports, applied military and drill training. No evidence-based methods of establishing nutrient requirements of children in modern conditions of cadet corps have been developed so far, which predetermines the potential of transforming nutrition from a health-saving factor into a health risk factor. Our objective was to provide a scientific substantiation of the model of healthy nutrition for students of cadet-type educational establishments. Methods: The statistical significance of the correlation was evaluated using the Student’s t-test. Correlation and regression analyses were used to assess cause-and-effect relationships. The Pearson correlation coefficient (rxy) was used as an indicator of the strength of the relationship between quantitative indicators x and y, both having a normal distribution. Correlation coefficient (rxy) values were interpreted in accordance with the Chaddock scale. For the purpose of statistical modeling, the method of multiple linear regressions was used. Conclusions: We substantiated the innovative model of organizing healthy nutrition for students of cadet-type schools based on the correlation and regression analyses with determination of statistical significance of the studied characteristics. Its efficiency indicators include an increase in average functional capabilities of students by more than 10 % and a reduction in the probability of developmental disorders by more than 25 %.

Introduction: Animal models have been used to understand the pathophysiology of pulmonary hypertension, to describe the mechanisms of action and to evaluate promising active ingredients. The monocrotaline-induced pulmonary hypertension model is the most used animal model. In this model, invasive and non-invasive hemodynamic variables that resemble human measurements have been used. Aim: To define if non-invasive variables can predict hemodynamic measures in the monocrotaline-induced pulmonary hypertension model. Materials and Methods: Twenty 6-week old male Wistar rats weighing between 250-300g from the bioterium of the Universidad del Valle (Cali - Colombia) were used in order to establish that the relationships between invasive and non-invasive variables are sustained in different conditions (healthy, hypertrophy and treated). The animals were organized into three groups, a control group who was given 0.9% saline solution subcutaneously (sc), a group with pulmonary hypertension induced with a single subcutaneous dose of Monocrotaline 30 mg/kg, and a group with pulmonary hypertension with 30 mg/kg of monocrotaline treated with Sildenafil. Right ventricle ejection fraction, heart rate, right ventricle systolic pressure and the extent of hypertrophy were measured. The functional relation between any two variables was evaluated by the Pearson correlation coefficient. Results: It was found that all correlations were statistically significant (p <0.01). The strongest correlation was the inverse one between the RVEF and the Fulton index (r = -0.82). The Fulton index also had a strong correlation with the RVSP (r = 0.79). The Pearson correlation coefficient between the RVEF and the RVSP was -0.81, meaning that the higher the systolic pressure in the right ventricle, the lower the ejection fraction value. Heart rate was significantly correlated to the other three variables studied, although with relatively low correlation. Conclusion: The correlations obtained in this study indicate that the parameters evaluated in the research related to experimental pulmonary hypertension correlate adequately and that the measurements that are currently made are adequate and consistent with each other, that is, they have good predictive capacity.

Objective: Accurate assessment of breast tumor size preoperatively is important for the initial decision-making in surgical approach. Therefore, we aimed to compare efficacy of mammography and ultrasonography in ductal carcinoma in situ (DCIS) of breast cancer. Methods: Preoperative mammography and ultrasonography were performed on 104 women with DCIS of breast cancer. We compared the accuracy of each of the imaging modalities with pathological size by Pearson correlation. For each modality, it was considered concordant if the difference between imaging assessment and pathological measurement is less than 0.5cm. Results: At pathological examination tumor size ranged from 0.4cm to 7.2cm in largest diameter. For mammographically determined size versus pathological size, correlation coefficient of r was 0.786 and for ultrasonography it was 0.651. Grouped by breast composition, in almost entirely fatty and scattered areas of fibroglandular dense breast, correlation coefficient of r was 0.790 for mammography and 0.678 for ultrasonography; in heterogeneously dense and extremely dense breast, correlation coefficient of r was 0.770 for mammography and 0.548 for ultrasonography. In microcalcification positive group, coeffient of r was 0.772 for mammography and 0.570 for ultrasonography. In microcalcification negative group, coeffient of r was 0.806 for mammography and 0.783 for ultrasonography. Conclusion: Mammography was more accurate than ultrasonography in measuring the largest cancer diameter in DCIS of breast cancer. The correlation coefficient improved in the group of almost entirely fatty/ scattered areas of fibroglandular dense breast or in microcalcification negative group.
