Internationalization in Higher Education – International Student’s Chinese Learning as Serious Leisure in Taiwan

Due to the economic and commercial rise of China, the economic value, political value, and instrumental advantages produced by Chinese have become more significant. The fever for learning Chinese continues to intensify all over the world, and Chinese instruction has become increasingly popular. Taiwan is a country with Chinese as its official language; and an important issue rose in international educational policy is how to attract international students to study Chinese in Taiwan. At the same time, Taiwan has promoted the internationalization of universities in the recent years; it hopes to elevate the visibility of its universities on the international stage, and intends to broaden diplomacy and promote economic development. This study found that international students who came to Taiwan to learn Chinese tended to be Asians. The different original residence locations of international students would significantly affect learning Chinese as serious leisure. International students who rented apartments with others off-campus or who chose home-stays had greater life planning, effort in Chinese learning, continuous benefits from Chinese learning, and a sense of community identification with their learning peers, as compared to international students who lived in school dormitories or lived alone off-campus. International students who had mor e disposable income each month were more likely to gain lasting benefits from Chinese learning and strong community identification with their learning peers.

L'enthouiasme pour apprendre le chinois continue de s'intensifier dans le monde entier, et l'enseignement du chinois est devenu de plus en plus populaire. La langue officielle de Taiwan est le chinois, et l'une des questions importantes dans la politique éducative internationale est de savoir comment attirer des étudiants étrangers à étudier le chinois à Taiwan. En même temps, Taiwan a favorisé l'internationalisation des universités dans les années récentes. Il espère rehausser la visibilité de ses universités sur la scène internationale et il a l'intention d'élargir la diplomatie et promouvoir le développement économique. Cette étude a révélé que les étudiants étrangers qui sont venus à Taiwan pour apprendre le chinois sont plutôt des Asiatiques. Les localisations différentes de résidence originale des étudiants étrangers auraient une influence significative sur leur apprentissage du chinois en tant que loisir sérieux. Les étudiants étrangers qui ont loué des appartements avec d'autres étudiants en dehors du campus ou ceux qui ont choisi une famille d'acceuil avaient une planification de vie plus longue et un effort d'apprendre le Chinois plus grand. Ils bénéficiaient des avantages continus de l'apprentissage du chinois et avaient un sentiment d'identification de communauté avec leurs partenaires de l'apprentissage, par rapport aux étudiants étrangers qui vivaient dans les dortoirs scolaires ou vivaient seuls en dehors du campus. Les étudiants étrangers qui avaient un revenu disponible plus élevé chaque mois étaient plus susceptibles d'obtenir des avantages durables de l'apprentissage du chinois et avaient une identification forte de communauté avec leurs partenaire de l'apprentissage.

NERVE CONDUCTION VELOCITY INVESTIGATION IN ATHLETES WITH TRAINED LOWER EXTRAMITY FOR WELL·CONTROLLlNG MOVEMENT

Reaction, coordination and speed ability are essential for success in a variety of sports. Nerve conduction velocity (NCV) is related to all of these abilities. Previous studies had investigated power and endurance type athletes, but there is less research in athletes who are skilled in coordinated lower extremity movements requiring more neural adaptation for nerve conduction velocity after specific exercise training. The purpose of this study is to investigate nerve conduction velocity of soccer, sanshou players and untrained subjects. Results show that NCV was significantly different among the 3 groups (p < .05) for the femoral and tibal nerves. For both femoral and tibial nerve.§, results showed that the soccer players had significantly faster NCV than the other groups (p < .05). According to the results, faster NCV adaptation from long term training in soccer players may be relate to their movement requirement of changing their movement direction quickly and skillfully

The Non-linear Relationship between Muscle Voluntary Activation Level and Voluntary Force Measured by the Interpolated Twitch Technique

Interpolated twitch technique (ITT) is a non-invasive method for assessing the completeness of muscle activation in clinical settings. Voluntary activation level (VA), measured by ITT and estimated by a conventional linear model, was reported to have a non-linear relationship with true voluntary contraction force at higher activation levels. The relationship needs to be further clarified for the correct use by clinicians and researchers. This study was to established a modified voluntary activation (modified VA) and define a valid range by fitting a non-linear logistic growth model. Eight healthy male adults participated in this study. Each subject performed three sets of voluntary isometric ankle plantar flexions at 20, 40, 60, 80 and 100% maximal voluntary contraction (MVC) with real-time feedback on a computer screen. A supramaximal electrical stimulation was applied on tibia nerve at rest and during contractions. The estimated VA was calculated for each contraction. The relationship between the estimated VA and the actual voluntary contraction force was fitted by a logistic growth model. The result showed that according to the upper and lower limit points of the logistic curve, the valid range was between the 95.16% and 10.55% MVC. The modified VA estimated by this logistic growth model demonstrated less error than the conventional model. This study provided a transfer function for the voluntary activation level and defined the valid range which would provide useful information in clinical applications

r-Hint: A message-efficient random access response for mMTC in 5G networks

Massive Machine Type Communication (mMTC) has attracted increasing attention due to the explosive growth of IoT devices. Random Access (RA) for a large number of mMTC devices is especially difficult since the high signaling overhead between User Equipments (UEs) and an eNB may overwhelm the available spectrum resources. To address this issue, we propose “respond by hint” (r-Hint), an ID-free handshaking protocol for contention-based RA in mMTC. The core idea of r-Hint is to avoid sequentially notifying contending UEs of their IDs by broadcasting a hint in the RA Response (RAR). To do so, we exploit the concept of prime factorization and hashing to encode the hint such that UEs can extract their required information accordingly. Our simulation results show that r-Hint reduces the RAR message size by 20%–40%. Such reduction can be translated to around 50% improvement of spectrum efficiency in LTE-M

On Scalable Service Function Chaining with O(1) Flowtable Entries

The emergence of Network Function Virtualization (NFV) enables flexible and agile service function chaining in a Software Defined Network (SDN). While this virtualization technology efficiently offers customization capability, it however comes with a cost of consuming precious TCAM resources. Due to this, the number of service chains that an SDN can support is limited by the flowtable size of a switch. To break this limitation, this paper presents CRT-Chain, a service chain forwarding protocol that requires only constant flowtable entries, regardless of the number of service chain requests. The core of CRT-Chain is an encoding mechanism that leverages Chinese Remainder Theorem (CRT) to compress the forwarding information into small labels. A switch does not need to insert forwarding rules for every service chain request, but only needs to conduct very simple modular arithmetic to extract the forwarding rules directly from CRT-Chain's labels attached in the header. We further incorporate prime reuse and path segmentation in CRT-Chain to reduce the header size and, hence, save bandwidth consumption. Our evaluation results show that, when a chain consists of no more than 5 functions, CRT-Chain actually generates a header smaller than the legacy 32-bit header defined in IETF. By enabling prime reuse and segmentation, CRT-Chain further reduces the total signaling overhead to a level lower than the conventional scheme, showing that CRT-Chain not only enables scalable flowtable-free chaining but also improves network efficiency

Emergence of topological phases from the extension of two-dimensional lattice with nonsymmorphic symmetries

Young and Kane have given a great insight for 2D Dirac semimetals with nontrivial topology in the presence of nonsymmorphic crystalline symmetry. Based on one of 2D nonsymmorphic square lattice structures they proposed, we further construct a set of 3D minimal tight-binding models via vertically stacking the 2D nonsymmorphic lattice. Specifically, our model provides a platform to generate three topologically semimetallic phases such as Dirac nodal line semimetals, Weyl nodal line semimetals and Weyl semimetals. The off-centered mirror symmetry sufficiently protects nodal lines emerging within mirror-invariant plane with a nontrivial mirror invariant $n_{M\mathbb{Z}}$, whereas twofold screw rotational symmetry protects nontrivial Weyl nodal points with topological charge $C=2$. Interestingly, Weyl nodal loops are generated without mirror symmetry protection, where nontrivial "drumhead" surface states emerge within loops. In the presence of both time-reversal and inversion symmetries, the emergence of weak topological insulator phases is discussed as well.Comment: 8 pages, 6 figures and 1 tabl
