Normal growth and development is of prime concern during childhood. The treatment of children with growth hormone deficiency has been revolutionized by growth hormone therapy. An improved height outcome with a final height within the target height range has been achieved. However, close follow-up with regular clinical and laboratory monitoring is essential for achieving the desirable height outcome. The theoretical unlimited supply of growth hormone has led to its wide spread use in a variety of disorders other than a growth hormone deficiency. Initially used in children with Turner syndrome, growth hormone is now used to treat chronic renal failure, an idiopathic short stature and intrauterine growth restrictions in addition to a wide array of newly emerging indications. This review summarizes the basics for a proper growth assessment, the differentiation of normal and abnormal growth causes of a short stature, and the indications for growth hormone treatment.

Currently, the argument that humanity will eventually reside in some sort of a simulated environment with unlimited resources is actively being discussed in the realm of science and engineering. This paper addresses the issue from the perspective of computer engineering, more specifically in terms of the future gaming environment which is very likely to be brought to us in the form of virtual reality probably in the not-so-distant future. In so doing, Bostrom's simulation argument[1]and Kurzweil's singularity[5] are reviewed, and how our future adobe indistinguishable from our 'real' reality that may be attained by explosive technological advancement relates to the future gaming environment. The problem of human consciousness which is inevitably intertwined with the issue of living in a virtual reality environment is also addressed.

Fine chemical production must assure high-standard product quality as well as characterized as multi-product production in small volumes. Installing high-precision batch distillation is one of the common elements in the successful manufacturing of fine chemicals, and the importance of the process operation strategy with quality assurance cannot be overemphasized. In this study, we investigate the optimal operation strategy and production planning of a sequential multi-purpose plants consisting of batch processes and batch distillation with unlimited intermediate storage. We formulated this problem as an MILP model. A mixed-integer linear programming model is developed based on the time slot, which is used to determine the production sequence and the production path of each batch. Illustrative examples show the effectiveness of the approach.

Animal-like robots are serving an important role as a linkage between biology and engineering. So, in this paper, we aim to develop a biomimetic microrobot that mimics the locomotion mechanism of a gastropod. This microrobot has 3 DOF (x, y translation and rotation), and has small size, unlimited traveling range, high resolution and low cost. Its movement can be made using propagation wave that is generated by the controllable sinusoidal voltage source and piezoelectric effects. This soft motion that can be generated by propagation wave and piezoelectric mechanism would be useful for the motion on the slippery surface. So we modeled the propagation wave mechanism including piezoelectric effect and friction on the contact surface, and could know the velocity of the microrobot is dependent on the driving frequency, input voltage peak, propagation wavelength and surface friction coefficient. With these results we design the microrobot, and accomplish its fabrication and experimentation. The development of this microrobot shall be aimed to design an autonomous moving actuator like animal. Also it can be used from micromanipulation system technology to biology and medicine.

The internet has been giving new business opportunities due to the unlimited and convenience of using it. So, A lot of companies confront many challenges to hold customer. In this situation, The holding many customers of online car insurance company could have very significant meanings, Therefore, this study could be meaningful to analyze the factor of building customer loyalty. The main results of the paper are as follows : Firstly, The attributes and recent situation of online car insurance have been researched. Secondly, The Customer brand relation quality(BRQ) has been shown a important role of building loyalty. Finally, Conceptual criteria for the study, which was modified considering cultural values of Korean customer from Fournier's seminal study, have shown very significant means.

Vertex shader of GPU in personal computer is advanced in functions as to be half of traditional fixed T&L functions. And, capacity of memory for saving resources to process instructions is unlimited. GPU that can be programmed by programmer is needed for mobile system as well as personal computer. In this paper, we implement software virtual machine for vertex shader using C++ Language. Our goal is designing hardware GPU that can apply to mobile system. The virtual machine consists of nVidia GPU instructions. Input Data to virtual machine is generated by Microsoft fxc compiler. That is to say, Input Data is compiled shader program written in HLSL, Cg, or ASM. The virtual machine will be a reference model for designing hardware GPU and can be used for Testbed to test added or modified instruction.

The ongoing COVID-19 pandemic once again demonstrated how crucial it is to have unlimited access to scientific information. At the same time, the economic disparities that the pandemic revealed and aggravated made us realize that many of us cannot afford access to expert knowledge. While the international community is speculating about possible outcomes of the crisis, one can be said for sure, the pandemic accelerated many inevitable changes that would otherwise happen at a slower pace including increasing digitalization of the society and the expanding role of open data in the life of the academic community.

With the introduction of the data-oriented plan for LTE service, one may concerned with the background of the ISP's policy in charging for LTE services. In this work we investigate the latest usage patterns of voice and data applications for customers over the current mobile network, via which we investigate why mobile operators introduced data-oriented plans. To be specific, we collected the real-field data for the volume of voice and data traffic from the LTE network before the data-oriented plans were introduced. From the collected data we compute the absolute volume as well as the proportion of voice and data applications. From these observations we infer mobile operators' reasoning behind the decision to introduce data-oriented plans with unlimited voice calls over the mobile network.

GIS can be used on almost entire fields of the world, such as the national land management, environmental management, disaster management, enterprise activities, and general lives. GIS is called as an infrastructure of the knowledge information on the cultural society. For insuring the national power on the periods of the unlimited competition, it is very important to establish the national information infrastructure. Purpose of the NGIS project I is to development on living benefits of peoplethrough an efficiency of policy and rationalism of planning. In order to achievement of this purpose, the NGIS project I has been established using the national geographic information base planning. The NGIS project I consists of the master management part, the geographic information part, the technique development part, the standardization part, and the land Information part. These five GIS project parts are operated by four governmental ministers and related institutions, such as minister of transportation and construction, minister of science and technology, minister of information and communication, minister of administrative and home affaires. The NGIS I project is to establishment of the nation spatial information systems, such as various nationwide digital maps, GIS technique development, GIS education, GIS standardization, and GIS researches.
