A Case Study on Learning Effectiveness of Information and Communication Security

In recent years, incidents related to information and communication security have been very common, therefore the reinforcement on education of information and communication security and the training of its professionals have become very important. Nevertheless, it is not an easy job to develop such professionals due to the great diversity in information and communication security field. Many experts and specialists believed that good teaching materials will facilitate educating and training of professionals. Unfortunately, traditional teaching materials on information and communication security are mostly based on theories, tools and skill development and lack elements of interesting design for stimulating learners' self learning desires and guidance. Learners lose interests and confidence easily because the teaching materials are too difficult to inspire their learning motivation. Digital game-based teaching materials are considered effective on promoting the learners confidence and learning motivation. This research constructs a teaching material for educating information and communication security that allows a user to learn with the speed and contents according to his or her own need. A case study also conducted in this paper. It shows that digital game-based teaching material efficiently promotes the learning effectiveness.

Sustaining the higher education hub model: the challenge of adequate academic and social support structures for international students / Cameron Richards and Mohd Ismail Abd Aziz.

In recent years, the Education Hub (EH) concept has perhaps become the single most important focus of higher education policy in most Asian countries. A particular Asian Education Hub model (e.g. Cheng, 2010) is now globally influential with its emphasis on how governments can harness direct as well as indirect economic benefits of a higher education system. Such a model aims to prepare students for employment in an emerging global economy and also to attract fee-paying international students in terms of education as not just a public good but a key and increasingly important area of national investment and economic development. In a related paper which focused on a comparison between distinct Malaysian and Singaporean versions of Asian EH l models developed over the last two decades (Richards, 2011c), we investigated the dangers as well as opportunities at stake. In this paper, we investigate the linked idea that sufficient academic and social support structures for supporting international as well as local students provide the crucial key to the factors of sustainability needed to support the various versions of the general strategy of Higher Education internationalisation.
Joinable Parallel Balanced Binary Trees

In this article, we show how a single function, join, can be used to implement parallel balanced binary search trees (BSTs) simply and efficiently. Based on join , our approach applies to multiple balanced tree data structures, and a variety of functions for ordered sets and maps. We describe our technique as an algorithmic framework called join-based algorithms. We show that the join function fully captures what is needed for rebalancing trees for a variety of tree algorithms, as long as the balancing scheme satisfies certain properties, which we refer to as joinable trees. We discuss four balancing schemes that are joinable: AVL trees, red-black trees, weight-balanced trees, and treaps. We present a variety of tree algorithms that apply to joinable trees, including insert , delete , union , intersection , difference , split , range , filter , and so on, most of them also parallel. These algorithms are generic across balancing schemes. Many algorithms are optimal in the comparison model, and we provide a general proof to show the efficiency in work for joinable trees. The algorithms are highly parallel, all with polylogarithmic span (parallel dependence). Specifically, the set-set operations union , intersection , and difference have work \( O(m\log (\frac{n}{m}+1)) \) and polylogarithmic span for input set sizes \( n \) and \( m\le n \) . We implemented and tested our algorithms on the four balancing schemes. In general, all four schemes have quite similar performance, but the weight-balanced tree slightly outperforms the others. They have the same speedup characteristics, getting around 73 \( \times \) speedup on 72 cores (144 hyperthreads). Experimental results also show that our implementation outperforms existing parallel implementations, and our sequential version achieves close or much better performance than the sequential merging algorithm in C++ Standard Template Library (STL) on various input sizes.

The Adverse Effect of Gaming Disorder on the Family System in the Society

BACKGROUND: The Internet has been a part of life and the development of technology. Internet addiction is one of the problems among adolescents, especially in Indonesia. Family dysfunction is thought to be a factor causing Internet addiction in adolescents. Family cannot always supervise adolescents, and adolescents are required to have good self-control to avoid problematic gaming behavior and online game addiction. If not taken seriously, game addiction can interfere with the physical and mental health of adolescents. AIM: This study aimed to identify the relationship between family functioning and Internet gaming disorder among adolescents in Aceh. Currently, Aceh is the only province in Indonesia implementing sharia (the Islamic law). METHODS: This was a quantitative study with a descriptive correlational method. The samples of this study were 157 male senior high school students. This research was conducted from January to April 2021. Data were collected by a self-report questionnaire and analyzed using the logistic analysis to identify the correlation between family functioning and Internet gaming disorder. RESULTS: The results showed that family functions such as communication functions (p = 0.034), affective engagement (p = 0.006), and behavioral control (p = 0.000) were significantly related to Internet gaming disorders in adolescents. This assumption is evidenced by the results of statistical tests that show a value (<0.05). While the problem-solving function (p = 0.916) and the general function (p = 0.606) obtained a significant value (>0.05) so it can be concluded both of these family functions were not related to Internet gaming disorder. CONCLUSION: The family functions are significantly related to Internet gaming disorders in adolescents. Maximizing family functions is one solution to prevent Internet gaming disorders in adolescents.
Teamwork and performance in professional women's football: A network-based analysis

Analysis of the underlying tactics and teamwork in women's football is rare and it is unknown how professional women's teams cooperate to be successful. The aim of this study was to investigate teamwork using network analysis while comparing match-outcome, match-type, ladder halves and tournament phases, to determine whether teamwork is related to success. Ball transfer data in 694 matches from the 2015, 2016 and 2017/18 Football Association Women's Super League (FA WSL) seasons; 2016–2018 National Women's Football League (NWSL) seasons; 2013 and 2017 European Cups; and 2011 and 2013 World Cups were analysed. The network metrics: edge density, transitivity, mean distance, out degree centrality, closeness centrality, betweenness centrality and eigenvector centrality were calculated. Success was categorised in match outcomes, ladder halves, tournament phases and ladder positions. It was found that successful professional women's football teams are highly connected (p = 0.006), and the distribution of ball possession is centralised (p = 0.001). There is a tendency for key players to send out a high number of passes, but there is no dependency on these key players for the total ball flow within a team, which is a characteristic that may be unique to women's football. Differences in teamwork exist between single matches and full seasons or tournaments, with successful teams having more effective ball movement and successful passes over the course of a season or tournament (p < 0.001). Moreover, successful league teams have more players with connecting roles than tournament teams and match tactics should be adapted to this.
Users' Design Process in Immersive Environments

The purpose of this study is to investigate the potential of immersive environments in the design domain by analyzing students' design process in immersive environments from cognitive and experiential aspects. To do this, we reviewed major concepts and theories such as users’ immersion, participation, presence, and awareness and developed a comprehensive conceptual framework of immersive shared environments. In three different visualization systems of HIVE, teams consisting two students were assigned to design tasks and the design process was analyzed by a customized framework. The characteristics of the immersive environment related to the performance of the design task were different from those of the previous studies. The perception of the relationship between the spaces is very important, and the perception of the surrounding objects is interested in the shape or the material such as whether the object is flat or inclined. Also, it is found that the multi-technology of immersive environments is very useful for creative collaboration. In the future, a more comprehensive analysis of the effects on design decisions in a more diverse visual interface condition and the effects on more diverse design areas should be added.
Targeted Cancer Therapy via pH-Functionalized Nanoparticles: A Scoping Review of Methods and Outcomes

(1) Background: In recent years, several studies have described various and heterogenous methods to sensitize nanoparticles (NPs) to pH changes; therefore, in this current scoping review, we aimed to map current protocols for pH functionalization of NPs and analyze the outcomes of drug-loaded pH-functionalized NPs (pH-NPs) when delivered in vivo in tumoral tissue. (2) Methods: A systematic search of the PubMed database was performed for all published studies relating to in vivo models of anti-tumor drug delivery via pH-responsive NPs. Data on the type of NPs, the pH sensitization method, the in vivo model, the tumor cell line, the type and name of drug for targeted therapy, the type of in vivo imaging, and the method of delivery and outcomes were extracted in a separate database. (3) Results: One hundred and twenty eligible manuscripts were included. Interestingly, 45.8% of studies (n = 55) used polymers to construct nanoparticles, while others used other types, i.e., mesoporous silica (n = 15), metal (n = 8), lipids (n = 12), etc. The mean acidic pH value used in the current literature is 5.7. When exposed to in vitro acidic environment, without exception, pH-NPs released drugs inversely proportional to the pH value. pH-NPs showed an increase in tumor regression compared to controls, suggesting better targeted drug release. (4) Conclusions: pH-NPs were shown to improve drug delivery and enhance antitumoral effects in various experimental malignant cell lines.

Short-pulse propagation in fiber optical parametric amplifiers

Fiber optical parametric amplifiers (FOPAs) are attractive because they can provide large gain over a broad range of central wavelengths, depending only on the availability of a suitable pump laser. In addition, FOPAs are suitable for the realization of all-optical signal processing functionalities and can operate with a potentially low noise figure with respect to erbium-doped fiber amplifiers and Raman amplifiers, when working in phase-sensitive configurations. A characterization of the signal distortion mechanisms introduced by FOPAs is relevant for investigating the applicability of FOPAs for the amplification of high speed signals with bit rates in excess of 1 Tbit/s per wavelength channel. The work presented in this thesis focuses on the distortion mechanisms affecting signals amplified by single-pump phase-insensitive FOPAs. The noise due to the cross coupling between the signal and the pump is also investigated. The pump-to-signal noise transfer has been recognized as one of the major noise source in FOPAs. This is due to the fast response of FOPAs (few fs), because of which intensity fluctuations of the pump cause an instantaneous gain modulation. The intensity modulation transfer from the pump to the signal is experimentally investigated for pump modulation frequencies up to 27 GHz and also in the saturation regime. A good agreement is found both with the theoretical model in the case of an undepleted pump and with the numerical results in the saturation regime, showing that the intensity modulation transfer can be reduced in saturated F OPAs. In characterize such effect, affecting multi-terabit per second per channel, fs considered. short fiber laser fiber-systems reliability, long-term stability compactness. promising broad investigated in a single-pump fiber optical chirped pulse amplification sc heme. First, a dynamic characterization is carried out both in unsaturated and saturated regimes and, then, amplification of short pulses compatible with Tbaud systems is experimentally demonstrated for the first time. This opens the way to the demonstration of a first broadband amplification scheme for highspeed signals reaching multi-terabit per second per channel.
Dynamic Detection and Placement for VSFs over Edge Computing Scenarios: An ACO-Based Approach

As an extension of cloud computing, the edge computing has become an important pattern to deal with novel service scenarios of the Internet of Everything (IoE), especially for the rapidly increasing different kinds of service requests from edge equipment. It is still a great challenge to satisfy the demands of delay-sensitive applications, so as to optimize the service provision delay for edge equipment under 5G. In this paper, by introducing virtualized service functions (VSFs) into edge computing pattern, the mechanism of service function detection and placement among multiple Edge Computing Servers (ECSs) is proposed. We firstly improve the Ant colony optimization (ACO) method to adapt to the situation that the service requests may frequently change from different edge network domains. Based on the improved ACO, a scheme of searching for the locations (i.e., ECSs) of the requested service functions is devised, so as to optimize the service searching delay. Then, a service function placement scheme is presented, and it deploys most of appropriate service functions in each ECS by predicting the future requested frequencies of functions, which further reduces the overall service provision delay. In addition, it also improves the ECS computing capacity utilization. The simulation results show that the proposed mechanism is feasible and effective.
The coupled strength and toughness of interconnected and interpenetrating multi-material gyroids

The growth of additive manufacturing technologies has spurred interest in examining multi-material micro-architected materials for filling the so-called white spaces in the Ashby strength versus toughness plots. We investigate this problem using interconnected and interpenetrating double gyroids comprising ductile and brittle phases as an exemplar. Both strength and toughness at the initiation of crack growth are shown to vary non-monotonically with the volume fraction of the two phases and multi-material double gyroids significantly outperform their single material counterparts. However, we establish that at a given relative density, the strength and toughness cannot be simultaneously enhanced for architecture designs, which include varying gyroid orientations, phase volume fractions, and the unit cell length scales of the two phases. Intriguingly, even crack flank bridging by the ductile phase during crack growth is insufficient to overcome this inherent property of the interpenetrating gyroids. Our conclusion is that multi-material interpenetrating micro-architected solids are unlikely to outperform single material non-interpenetrating lattices from a strength–toughness perspective but rather become optimal when multi-functionality is required. The integration of materials and architectural features at multiple scales into structural mechanics gave us structural designs such as the Eiffel Tower. The explosion of additive manufacturing methods has opened new avenues for the invention of multi-material micro-architected materials that simultaneously possess high strength and toughness at a low density, and thereby can fill the so-called “white spaces” in the Ashby strength–toughness space. The idea is to construct three-dimensional materials with a network of crack arrestors like in rip-stop nylon and break the link between toughness and strength. We use interconnected and interpenetrating double gyroids comprising ductile and brittle phases as an exemplar to investigate the opportunities of such designs. Intriguingly, from a perspective based solely on strength and toughness, we show that multi-material micro-architectures cannot outperform their single material counterparts at a given relative density. In fact, in most designs the coupling between the two phases is non-synergistic. Rather, we argue that multi-material designs such as those used in rip-stop nylon are driven by multi-functional considerations beyond mechanical properties.
Differences in age at diagnosis of ovarian cancer for each BRCA mutation type in Japan: optimal timing to carry out risk-reducing salpingo-oophorectomy

Objective BRCA1 and BRCA2 mutation carriers are recommended to undergo risk-reducing salpingo-oophorectomy (RRSO) by age 40 and 45, respectively. However, the carriers have a different way of thinking about their life plan. We aimed to investigate the distribution of age at diagnosis of ovarian cancer (OC) patients to examine the optimal timing of RRSO in the carriers. Methods We examined a correlation between age at diagnosis of OC and common mutation types in 3,517 probands that received BRCA genetic testing. Among them, germline BRCA1 mutation (gBRCA1m), germline BRCA2 mutation (gBRCA2m) and germline BRCA wild-type (gBRCAwt) were found in 185, 42 and 241 OC patients, respectively. Results The average age at diagnosis of OC in gBRCA1m and gBRCA2m was 51.3 and 58.3 years, respectively, and the difference from gBRCAwt (53.8 years) was significant. The gBRCA2m carriers did not develop OC under the age of 40. The average age was 50.1 years for L63X and 52.8 years for Q934X in BRCA1, and 55.1 years for R2318X and 61.1 years for STOP1861 in BRCA2. The age at diagnosis in L63X or R2318X carriers was relatively younger than other BRCA1 or BRCA2 carriers, however their differences were not significant. With L63X and R2318X carriers, 89.4% (42/47) and 100% (7/7) of women were able to prevent the development of OC, respectively, when RRSO was performed at age 40. Conclusion There appears to be no difference in the age at diagnosis of OC depending on the type of BRCA common mutation. Further analysis would be needed.
An Ultra-Wideband Image-Reject Up-Conversion Mixer With a Sandwich-Coupled Transformer for 5G mm-Wave Communication

This letter presents an ultra-wideband 20–42 GHz image-reject up-conversion mixer with low dc-power consumption implemented in 55 nm CMOS technology for multiband mm-Wave 5G systems. A sandwich-coupled transformer (SCT) is adopted to expand the operation bandwidth. The proposed SCT demonstrates good performance in enhancing the coupling coefficient and quality factor, which enables wideband impedance matching. Moreover, a quadrature signal generator composed of a transformer and a polyphase filter (PPF) is utilized to generate wideband high-precision I/Q signals without any calibration. With only 24 mW dc-power consumption, the mixer exhibits excellent conversion gain flatness of 1.2±1.5 dB from 20 to 42 GHz. The measured image reject ratio (IRR) is better than −30 dBc within the entire operation band. The measured output 1-dB compression point (OP1 dB) is −2.57 dBm at 28 GHz and −3.96 dBm at 38 GHz. The proposed mixer exhibits good broadband characteristics, which can sustain multiband operation.
