The mobile instant messengers could change the lives of average citizens as much as did the telephone in the early part of the 20th century and television in the 1950s and 1960s. Researchers are debating whether the mobile instant messengers are improving or harming participation in community life and social relationships. For this study, 155 participants in two universities completed questionnaires pertaining to their own mobile instant messengers use and feelings of loneliness. We used survey data to examine the effects of the mobile instant messengers on social involvement and psychological well-being. In this sample, the mobile instant messengers were used extensively for communication. Results suggest that greater use of the mobile instant messengers were associated with declines in participants' communication with the people around which in turn creases their loneliness. These findings have implications for research and for the design of technology.

Objectives: Current studies are debating on the association of vascular calcification and the benefit of treatment to lower serum phosphorus level in patients with chronic kidney disease. The aim of this study was to evaluate the association of mortality and risk of vascular calcification in patients with CKD who were taking phosphate binders. Methods: This study was conducted through retrospective medical chart review for 420 patients aged 18 years and older who were admitted for chronic kidney disease. Results: Vascular calcification was not statistically significantly associated with increased mortality in patients with CKD [16.7% vs. 19.2%; 95% CI; 0.388 to 1.818 (p=0.656)]. Intervention of calcium-based phosphate binders was not significantly associated with vascular calcification in patients with CKD [9.1% vs. 12.5%; 95% CI; 0.364 to 1.358 (p=0.292)]. Ca x P product ${\geq}55mg^2/dL^2$ was not significantly associated with increased 1 year mortality in patients with CKD [25.4% vs. 17.5%; 95% CI; 0.851 to 3.013 (p=0.142)]. Intervention of sevelamer was significantly associated with reduced 1 year mortality in patients with CKD than that of patients who did not take sevelamer [6.3% vs. 25.3%; 95% CI; 0.044 to 0.880 (p=0.020)]. Conclusion: There was not a statistically significant association between vascular calcification and phosphate binder's use. But phosphate binder use was significantly associated with decreased mortality in patients with CKD.

As in some developing countries and more recently some developed countries worldwide and in the Asian region, Australia has faced significant internal opposition and public debate especially over treaty-based investor-state dispute settlement (ISDS). As outlined in Part II(1), concerns have re-emerged and escalated since the first-ever claim was brought against Australia regarding its tobacco plain packaging legislation, in 2011 by Philip Morris Asia under an old BIT with Hong Kong. However, Australia signed bilateral FTAs with Korea in 2014 and with China in 2015, including ISDS protections, prompting several sets of parliamentary inquiries (Part II(2)). Australia's close trading partner, New Zealand, had already concluded an FTA with China in 2008 that included more expansive ISDS-backed investor protections. In 2015, the New Zealand Parliament has been debating ratification of its own FTA with Korea, with ISDS also now attracting growing scrutiny, as elaborated in Part III below. In both bilateral FTA negotiations, the present Korean government seems to have reverted to a strong preference for concluding investment agreements with extensive ISDS protections, despite public and parliamentary debate around 2011 in the context of ratifying its FTA with the United States. As mentioned briefly in the concluding Part IV, Korea's stance has significant implications for the future trajectory of treaty-based ISDS - and indeed international arbitration more generally - in the Asia-Pacific region, and perhaps even globally.

Epicondylitis, as a tendinopathy characterized by fibroblast and microvascular hyperplasia, is a common musculoskeletal problem especially related with repetitive hand and wrist motion. It has a prevalence of between 0.2% and 5% in general population depending on the amount of exposure to manual labor jobs. Although it is known that the pathological lesions lie in the flexor or extensor common tendons, there could be collateral ligament lesions and/or reactive synovitis accompanied, which may make a case unresponsive to the treatment aimed only at the tendinopathy. Epicondylitis is easy to diagnose with typical pain, tenderness, and positive provocation tests. However, many conditions can mimic epicondylitis that further imaging or electrodiagnostic studies should be undertaken to exclude other possible problems. Ultrasonography provides information about the existence and extent of tendinopathy with relatively high specificity. Magnetic resonance imaging is often required to rule out other problems and confirm the diagnosis of the cases intractable to long term treatment. Many options of treatment are available for epicondylitis while numerous conflicting evidences have been noted, debating one treatment method is better than the others. Since it was reported that over 80% of epicondylitis improved within a year no matter what was done as treatment, it is a challenge to make accurate diagnosis and combine effective therapeutic regimens for the 20% of intractable cases.

The cardiovascular syndrome is the dominant reason for death and the number of deaths due to this syndrome has greatly increased recently. Regular cardiac monitoring is crucial in controlling heart parameters, particularly for initial examination and precautions. The quantity of cardiac patients is rising each day and it would increase the load of work for doctors/nurses in handling the patients' situation. Hence, it needed a solution that might benefit doctors/nurses in monitoring the improvement of the health condition of patients in real-time and likewise assure decreasing medical treatment expenses. Regular heart monitoring via wireless body area networks (WBANs) including implantable and wearable medical devices is contemplated as a life-changing technique for medical assistance. This article focuses on the latest development in wearable and implantable devices for cardiovascular monitoring. First, we go through the wearable devices for the electrocardiogram (ECG) monitoring. Then, we reviewed the implantable devices for Blood Pressure (BP) monitoring. Subsequently, the evaluation of leading wearable and implantable sensors for heart monitoring mentioned over the previous six years, the current article provides uncertain direction concerning the description of diagnostic effectiveness, thus intending on making discussion in the technical communal to permit aimed at the formation of well-designed techniques. The article is concluded by debating several technical issues in wearable and implantable technology and their possible potential solutions for conquering these challenges.

The international government committee is progressing their agreements about intellectual property protection of traditional knowledge(TK), gene resource(GR), folklore(FL) in WIPO. It is in the course of selection with precedence of TK, GR, FL in WIPO, focused on discussions about listing of TK documents, standardization of DB construction, sharing and profit distribution of GR. There are disagreements between developed countries and developing countries about intellectual property protection agreements of TK, GR. The developed countries insist on using the existing intellectual property protection, but the developing countries ask new ones on character of TK, GR. It causes intangible assets to be valuable trade properties in future world trade. This research Groped for a summary program about intellectual property protection of traditional knowledge(TK) etc. debating in WIPO. This program confirms that such as TK, GR etc. not only to be the cultural property accumulated in human history, but also to be the original resource may be using at present. Therefore, we suggest that the focus of discussion should transfer to UNESCO instead of WIPO which only deal with the intellectual property protection. Besides, the main body which protecting and supporting TK should become its holding organization so as to achieve more effective management about it. In order to protect and support TK, the government should have firstly the recognition that TK is the property belongs to the country. By this viewpoint, it needs to setup DB through overall excavation of the unofficial knowledges in order to protect and support these TK, GR. Because the positive dealing with those WIPO's discussion means to support our TK, GR, so there should have some reorganization about existing related ones, and also needs systemic supporting policies & management' system.

This study has developed the earth science class model based on flipped learning and analyzed the effects of that model at the elementary pre-teachers' science classes. The model of this study, the material which was consists of all contents and information about classes was offered to learners before science class as a substitute for preceding homework at general flipped learning. In science class, the knowledges which were recorded in materials were explained directly to learners by instructor for 20minutes. So the learners resolved some inquiry questions in materials through mutual debate collaboration with learners in small group. After inquiry questions' resolving, the learner among small group makes a presentation in front of the whole class. At the same time, the instructor evaluated learning action of all small groups' learners during the classes as process evaluation. The final evaluation results of semester were obtained scores of the small group in 14 classes and the achievements of individual portfolio as final exam. The learners were very positive perception to this science class model, why it is helped to concentrate on the class, extended debating and thinking ability. Consequently, the class model of this study is useful to applicate the earth science classes.
