Abstract-Every web server poses a risk to network security threats. One of them is a threat of Slow HTTP Attack. Slow HTTP Attack exploits the working methods of the HTTP protocol, where it requires that every request from the client be fully accepted by the server before it is processed. If the HTTP request is incomplete, or if the transfer rate is very low, the server remains busy waiting for the rest of the data. If the server is storing too many busy resources, there is a denial of service. Internet users can exploit such vulnerabilities, send incomplete data packets deliberately and requests repeatedly. When a web server is in a public network or the Internet, then protecting the computer and network security is an important issue. After identifying and analyzing how the Slow HTTP attack works, as well as its attack detection, this paper describes a portfolio of the work system, how to detect and how to defense against the Slow HTTP attack.

The purpose of this study was to examine the effects of a group contingency strategy on student behaviors in elementary physical education classes. The study was conducted in an elementary school within metropolitan Korea. Eighty 6th-grade students (2 classes) and one teacher participated in this study. To investigate the effects of group contingency (intervention), two classes were separately designated as the experimental group (n=40) and control group (n=40). A multiple-baseline design across student target behaviors was used to determine the effects of exposure to behavioral intervention on student behaviors. Comparison was also made with the absence of the intervention. Data collected through each class observation and videotaping of 17 lessons of ball game and gymnastics showed that a group contingency strategy was effective in increasing the percentage of on-task behavior (motor activity) and reducing student waiting time and off-task in the experimental group. Compared to the experimental group, the control group showed no significant behavioral changes. Results also showed that the strategy was effective in decreasing inappropriate behavior and increasing appropriate behavior, which consequently builds on new forms of behavior by applying these contingencies consistently with effective consequences.

-The objective of this research was to determine the students' satisfaction level on the academic services provided by the accounting program at a private university in Jakarta and to evaluate attributes that should be improved. The data were obtained from questionnaires by using 5 quality dimensions. There are tangible, reliability, responsiveness, assurance, and empathy. Moreover, the data were processed by using Excel, SPSS 20, Customer Satisfaction Index (CSI) to determine the level of customer satisfaction, and also Importance-Performance Analysis (IPA) to determine the attributes of service be repaired and maintained. The results show that the CSI is 71%, which means that the majority of customers are satisfied with the performance of the service quality of accounting program. Meanwhile, the results of IPA indicate that the improvement priorities have two attributes in quadrant 1. They are the availability of space to support student activities and the availability of books and teaching materials related to the syllabus. These attributes are the top priority because the importance level is high while the performance level is low from the customers' point of view.

<p>This study aims to find out the empirical evidence of Indonesia capital market investors’ reaction toward presidential election 2019. The population in this study is the companies’ stocks which are included in the LQ-45 index during this study. The data used is secondary data in the form of LQ-45 stocks and daily Composite index three days before and three days after the event. By implementing the one sample t-test and paired samples t-test, the result shows that there is a positive and significant abnormal return around the event especially on the third day (t+3) after the event.  Moreover, there is an insignificant difference in the average of negative abnormal return and significant difference on the average of negative trading volume activity, before and after the presidential election 2019.</p><p><strong>Keywords:</strong> Capital Market, Event Study, Abnormal Return, Trading Volume Activity, Investors’ Reactions</p><p class="Default"><em>Penelitian ini bertujuan untuk menemukan bukti empiris reaksi investor pasar modal Indonesia terhadap peristiwa pemilihan presiden 2019.

Tujuan dari penelitian ini yaitu untuk mengatahui gambaran aktifitas fisik dan perilaku pasif yang dilakukan mahasiswa jurusan pendidikan olahraga selama masa pandemi COVID-19 ini terjadi. Pemetaan ini dilakukan dengan cara melakukan penelitian survei menggunakan angket yang diadopsi dari WHO yaitu Global Physical Activity Questionnaire (GPAQ). Soal pada angket ini sebanyak 16 soal yang didalamnya berupa pilihan jawaban dan perlu menambahkan deskripsi. Angket ini diberikan kepada seluruh mahasiswa yang menjadi sampel mulai angkatan 2017 hingga 2019. Teknik sampel yang digunakan yaitu simple random sampling. Analisis data pada penelitian ini terdiri atas tiga penghitungan yaitu rata-rata, sntadar deviasi, dan persentase. Hasil analisis menjelaskan bahwa mahasiswa laki-laki yang masih aktif melakukan aktifitas fisik cukup rutin sebanyak 53.7% dan 17.2% untuk perempuan dan mahasiswa yang dominan memiliki perilaku pasif dengan menghabiskan duduk atau berbaring santai setiap harinya yaitu mahasiswa laki-laki angkatan 2017 (3.7%) dan 2018 (10%), sedangkan 2019 (2.5%).

To remove a growing gap between students’ skills received in vocational high schools and real demands in the workforce, industries should be actively involved not only as external users but to work in curriculum development and learning evaluation. This study describes the process of planning, implementation, and supervision of an industry standard class resulted from collaboration between the school and the industry. This study was a qualitative study using data collection techniques of interviews, observation and documentation. The results revealed (1) the industry and the school were partners in planning the industry standard class including development of curriculum, facilities, infrastructure, teachers, and materials, (2) implementation of the class included theoritical and practical learning, and industry practices, (3) supervision was performed by the industry partner administrating industry standard competency tests, and (4) management of the class consisted of three sequenced stages namely selection of students in the third semester, implementation of industry standardized teaching and learning process from the third semester to the sixth semester, and a competency test in the sixth semester.

Someone will have a greater risk of experiencing heat strains if working at a workplace exposed to heat. In addition to the heat from the body's metabolic results and the result of heat exposure from the work environment, heat strain on workers also influenced by individual factors. The extent to which an individual's body can tolerate heat exposure is determined by the condition of his body. Physiological changes will occur in the body of workers who exposed to heat. The objective of this study was to analyse factors related to heat strain such as acclimatization, water intake adequacy rate, and individual characteristics. The research was an observational analytic study and study design that used was cross-sectional. The population chosen as the research subject was workers who were exposed to heat. Purposively 57 construction workers were selected as subjects. To prove the relationship between acclimatization, water intake adequacy rate, and individual characteristics with heat strain, it used chi square statistical test. Physiological Strain Index (PSI) used to assess heat strain event on workers. The results of outdoor WBGT measurements at the study site showed that the average of WBGT outdoor was 31.11 o C. Heat strain with high index experienced by the majority of workers as much as 82.5%. Result of statistical analysis showed the significance of each variable was acclimatization (p<0.05), water intake adequacy rate (p<0.05), alcohol and drug consumption (p>0.05), health status (p>0.05), body mass index (p<0.05), age (p>0.05), and work period (p>0.05). This study showed that there was a significant relationship between heat strain with acclimatization, water intake adequacy rate and body mass index. The relationship is evidenced by the results of bivariate analysis. However, there was no association between consumption of alcohol or drugs, health status, work period, and age with heat strain.
