Background: Soft tissue analysis is essential in treatment planning to ensure proportional, balanced, and harmonious soft tissue at the end of treatment. Several factors influence the variations, such as age and gender. Soft tissue profile analysis is usually studied from a lateral view. Purpose: The study aimed to determine whether there were differences in the average values of linear and angular measurement of the soft tissue profiles of the middle and lower third of the face between Chinese males and females high school students using lateral photometry. Methods: The samples were 100 lateral photographs (50 male and 50 female) of Chinese high school students at W.R. Supratman 1 and 2 in Medan. All samples were collected based on the inclusion and exclusion criteria obtained from secondary data. The linear and angular measurements were measured using Software Corel Draw 2019 and analysed statistically using an independent t-test and the Mann-Whitney test. Results: The inferior facial third, length of the lower lip, and prominence of the upper lip were, on average, greater in males, whereas in the prominence of pogonion, nasolabial angles, and nasofrontal angles were greater, on average, for females. Conclusion: There were significant gender differences in Chinese high school students in the inferior facial third, length of the lower lip, prominence of the upper lip, nasolabial angle, and nasofrontal angle, whereas there is no significant difference between genders in the prominence of the pogonion.

Many countries have incorporated computational thinking (CT) and programming languages into their science and technology courses. Students can improve their CT ability by learning programming languages. Moreover, situated learning enables students to generate knowledge and master problem-solving skills through interaction with situations. This study incorporated Webduino learning and the situated learning strategy into a programming course and analyzed its impact on high school students’ CT ability, learning motivation, and course satisfaction. A quasi-experimental research method was adopted, wherein the experimental group was subjected to the situated learning strategy and the control group was subjected to a traditional teaching method. The study results revealed that integrating Webduino programming with situated learning could effectively improve five categories of CT skills; moreover, the activity models of situated learning enhanced the value and expectation dimensions of learning motivation. In addition, satisfaction with the course content and self-identity slightly improved. However, because teachers were required to elaborate on stories to promote learner engagement with life situations, the time available for programming was limited. Thus, no significant difference was observed in teaching satisfaction.

Objective : To obtain objective average measurements of the profile and frontal facial soft tissue to be used as a guide for aesthetic treatment goals. Methods and Materials : This observational study included 110 females and 130 males high school students aged 16-18 years. None of the subjects had any facial deformities. All of them and their parents gave consent to take part in this study. In each case, two standard photographs of profile and frontal views were taken 27 landmarks were digitized on photographs. The mean, standard deviation, and range for a total of 43 facial indices were calculated digitally by computer software. The Student’s t-test was used to compare males and females. Results : The ratio between the lower and middle facial thirds was one to one, but the height of the upper facial third was proportionally smaller than the other two-thirds in both sexes. Boys had greater nasal length, depth, and prominence than girls with statistically significant differences. Both upper and lower lips were more prominent in girls than in boys. All measurements of the chin showed sexual dimorphism characterized by greater chin height and prominence and deeper mentolabial sulcus. Boys had greater facial dimensions than girls. Mouth width, nasal base width, and intercanthal distance were significantly greater in boys. Conclusion : The labial, nasal, and chin areas showed sexual dimorphism in most of the parameters used in this study. Boys had larger faces, greater facial heights, longer nasal, labial, and chin lengths, and greater nasal, labial, and chin prominence.

The possible relationships among creativity, intelligence, and self actualization were examined in 208 high school students to determine whether or not consistent self actualization scores existed for subjects high in the first two variables. Students high in both creativity and intelligence had significantly higher scores in self actualization than those obtained by students high in either creativity or intelligence. No significant difference in self actualization was found between students high in creativity only and those high in intelligence only. The results were interpreted as indicating that educational systems should stress both intellectual and creative abilities to achieve the highest level of psychological well being in students.

The present study sought to examine the relationship between Chinese high school students’ academic self-efficacy and their academic-related boredom. Another objective was to explore the moderating effects of mono-amine-oxidase type A ( MAOA) gene polymorphism on this relationship. In a sample of 514 Chinese high school students, we measured their academic self-efficacy and academic-related boredom from Grades 10 to 12. In addition, we collected their DNA. Data were analyzed by using a linear mixture model. The results indicated that students’ academic self-efficacy negatively predicted their academic-related boredom. The relationship between academic self-efficacy and academic-related boredom was more reliable for students with the 3-repeat allele than for the students with the 4-repeat allele. The findings suggested that the functional polymorphism of MAOA gene moderated the relationship between academic self-efficacy and academic-related boredom.

Peer assessment training has appeared as potential new tools for enhancing Arab English as foreign language (EFL) high school students on writing performance. The purpose of this research was to investigate the effect of using peer assessment training on writing performance among Arab EFL high school students. One hundred and twenty students aged fifteen and sixteen years old participated in this study with an equal number of male and female students. The students were from two Arab high schools in Malaysia. This study employed a quasi-experimental research design. Data was collected using Analytical Marking Scale (Alderson, et al., 1995) to assess student’s writing performance in the pretest and posttest. The result of this study shows that there is a significant difference in the writing performances between the experimental and control groups at P < 0.001. The findings suggests that students who have been exposed to peer assessment training write a better draft compared with those students who were only given conventional training in writing an essay, and without the benefit of peer feedback.

The aim of our study is to examine the cardiovascular endurance systems of sedentary high school students. The 112 sedentary individual was taken to the 1600 meter walking test run, and the 120 sedentary individual Harward step test. While both individuals were participating in the same test, weight, height, oxygen saturation, and heart rate of participants were measured before starting the test. As soon as the test is finished (recovery period), oxygen saturation and heart rate variability of individuals are measured at 1, 3, 5 minutes. All measured variables were analyzed and compared. Analysis of the data was done according to the SPSS statistical program and the significance level was accepted as p <0.05. In the 1600-meter walking test, it was observed that there was a significant difference in mean heart rate between males and females p<0.05. There was a significant difference between the mean values of the time of completion of the 1600 m running test by males and females (p < 0.05). During the 1600-meter walking and Harward step test recovery period, there was no difference in the participants' parameters. There was no significant difference between oxygen saturations at beginning, recovery 1st, 3rd, and 5th minutes in both tests. Significant differences were found between heart rate and oxygen saturation values (beginning, recovery 1st, 3rd, and 5th minutes) in the intra-group comparisons of both groups. Participants' heart rates began to increase with exercise, but remained above the initial heart rate level during recovery. Participants' body mass indexes were observed to be within normal values. We think that can be increased cardio respiratory and cardiovascular fitness levels and can been created lifelong exercise habits by regular exercise programs are given to Sedentary high school students. Thus, we believe that the young population can be prevented from getting sick by providing healthier, social, active individuals.

<p></p><p>This research has aimed to determine whether cyber-bullying peer violence is associated with depression, anxiety and stress in high school students. The research results are based on the data obtained from a sample of 202 Montenegrin high school students. It has been established that committing and experiencing e-violence is associated with depression. Committing and experiencing verbal online violence, as well as involvement in online counterfeiting/criminal acts, is associated with depression, while involvement in online identity concealment and lies has no connection with depression. When it comes to anxiety, the results of this research show that involvement in verbal e-violence and in online counterfeiting/criminal acts leads to anxiety, while committing and experiencing online identity concealmentis not related to anxiety. When it comes to committing and experiencing verbal online violence and stress, although there is a statistically significant difference, it is not applicable for all values. Consequently, we cannot draw a strong enough conclusion about it. Victims of online counterfeiting and criminal acts, according to the results of our research, have a higher level of stress than those not involved in this type of cyber-bullying peer violence.</p><p><i>Cyber victim and bullying scale </i>has been used to collect data on committing and experiencing e-violence among peers (Cetin, Yaman and Peker, 2011).Permission to use this scale was requested and obtained. The scale examines experiencing and committing online violence. It consists of two parts, each part containing 22 particles. In the first part (<i>Experiencing cyber-bullying </i>subscale), participants have assessed whether the described behavior happened to them,on a scale from 1 (never) to 5 (always). In the second part (<i>Committing cyber-bullying </i>subscale), and with identical particles, respondents have assessed whether they themselves behaved in this way. </p><p></p><p> </p><p><i>In our research, we have performed a factor analysis of the </i><i>Cyber victim and bulling scale .</i></p> <p>When it comes to the <i>Committing cyber-bullying </i>subscale, the percentage of explained variance amounts to 55.141%, whereas factor analysis also points to 3 factors, namely: a) verbal online violence; b) online identity concealment and lies; and c) online counterfeiting and criminal acts.</p> <p>When it comes to the <i>Experiencing cyber-bullying</i> subscale, the percentage of explained variance amounts to 65,211%, whereas factor analysis also points to 3 factors, namely: a) verbal online violence; b) online identity concealment and lies; and c) online counterfeiting and criminal acts.<i> W</i>e have used a scale for assessing the depression, anxiety and stress levels (DASS21) to determine whether experiencing e-violence leads to depression, anxiety and stress,and to what extent. We have chosen this scale because the results of a research checking its psychometric qualities have indicated that the DASS-21 scale’s psychometric qualities recommend it for use in researching unpleasant emotional states in adolescents. DASS-21 is a 21-item self-report measure giving three subclasses of seven items each: depression , anxiety and stress. Participants have been asked to indicate which statement applied to them over the past week on the Likert 4-point scale. DASS-21 has high reliability, consistent factor structure and high convergent valiadity. We did not have to ask permission for this scale and it can be used freely.</p><p></p>
