Background Citation analysis is a recognized scientometric method of classifying cited articles according to the frequency of which they have been referenced. The total number of citations an article receives is considered to reflect it's significance among it's peers. Methods Until now, a bibliometric analysis has never been performed in the specialty of craniofacial anomalies and craniofacial surgery. This citation analysis generates an extensive list of the 50 most influential papers in this developing field. Journals specializing in craniofacial surgery, maxillofacial surgery, plastic surgery, neurosurgery, genetics and pediatrics were searched to demonstrate which articles have cultivated the specialty within the past 55 years. Results The results show an intriguing compilation of papers which outline the fundamental knowledge of craniofacial anomalies and the developments of surgical techniques to manage these patients. Conclusions This citation analysis provides a summation of the current most popular trends in craniofacial literature. These esteemed papers aid to direct our decision making today within this specialty.

The book, "Euibangyoochui醫方類聚"(A.D. 1445) is called the treasure-house of the knowledge of medical science, due to the 50,000 prescriptions and an enormous amount of medical information that it contains. But in spite of the importance of this book, a convenient and efficient method to use the information in this book isn't developed yet and as a result the use of this book in a low state. Therefore before than anything else, there is necessity to establish the database on "Euibangyoochui". Before the establishment of database on "Euibangyoochui", there are basic works that should be preceded as follows; like the correction through investigating and comparing between the texts that are related with "Euibangyoochui", interpretation, proofread and translation to Korean of the original. And also bibliographical research on "Euibangyoochui". The compilatory course and transmissional system of the medical books in first term of Chosun(朝鮮) was able to apprehend through the bibliographical research about "Euibangyoochui". Also, many emergency medical books and books about the prevention of the infectious diseases mostly based on "Euibangyoochui" were wrote and put to practical use. And this fact, tells us that the compilation of "Euibangyoochui" was supported by the government of Chosun as means to accumulate the medical knowledge.

This paper discusses the development of the control system of a mini quadrotor in Konkuk University for indoor applications. The attitude control system consists of a stability augmentation system, which acts as the inner loop control, and a modern control approach based on modeling will be implemented as the outer loop. The inner loop control was experimentally satisfied by a proportional-derivative controller; this was used to support the flight test in order to validate the modeling. This paper introduces the mathematical model for the simulation and design of the optimal control on the outer loop control. To perform the experimental tests, basic electronic hardware was developed using simple configurations; a microcontroller used as the embedded controller, a low-cost 100 Hz inertial sensors used for the inertial sensing, infra-red sensors were employed for horizontal ranging, an ultrasonic sensor was used for ground ranging and a high performance propeller system built on an quadrotor airframe was also employed. The results acquired from this compilation of hardware produced an automatic hovering ability of the system with ground control system support for the monitoring and fail-safe system.

We recently witnessed increasingly more natural disturbances on forested land. On the other hand, only limited number of nursery grown tree species are available for restoration projects. At the same time, so little on the disturbance resistance of species has been studied that a selection of right species for right site condition becomes very difficult. This study is a compilation of the site specificities and disturbance resistance of each species native to South Korea. Each species was surveyed for 11 items related to site specificities, and 12 items related to disturbance resistance including the resistance to snow damage. This study was conducted for 161 tree species from 44 families : 21 evergreen conifer species, 2 deciduous conifer species, 18 evergreen broad-leaved species, 118 deciduous broad-leaved species, and 2 monocotyledon species. This study suggests that native species in South Korea show resistance to all types of natural disturbances except drought.

The neutron cross sections of $^{160}$ Dy, $^{161}$ Dy, $^{162}$ Dy, $^{l63}$Dy, and $^{164}$ Dy have been evaluated in the resonance region of which upper energy is set to several tens of keV. The cross sections are formulated with resonance parameters in the energy region under consideration. In the resolved resonance region, the positive-energy resonance parameters were adopted from the BNL compilation published in 1984 with slight, if any, modifications. A bound level resonance for each isotope except $^{162}$ Dy was invoked to reproduce the reference 2200 m/s cross sections and the bound coherent scattering length. Subsequently, the statistical behavior of the resolved resonance parameters was analyzed, and thus obtained s-wave average parameters were adopted in the unresolved resonance region. In addition, recent measurements of the capture cross sections in the unresolved region were taken into account in adjusting the average resonance parameters for high orbital angular momentum resonances. The present evaluation resulted in large improvements in the cross sections over the ENDF/B-Vl release 6.6.

Objectives : Zheng Zhi Xin Chuan(證治心傳) is a compact compilation of 14 discussions on medicine, written by Yuan Ban(袁班) in the late Ming-early Qing period. Methods : To survey the scholarly position of Yuan Ban(袁班) in the history of Wenbing by systematically analyzing and organizing Wenbing related theories in Zheng Zhi Xin Chuan (證治心傳). Results & Conclusions : In his book, YB suggests concepts such as 'mainly attack upper heater(多犯上焦)', 'transmission to the nutrient phase(轉入營分)', 'sequential transmission(順傳)', 'abnormal transmission(逆傳)', 'dryness invasion of human body in autumn(秋傷於燥)'. In the history of Wenbing, it has been widely acknowledged that the concept of weiqiyingxiebianzheng(衛氣營血辨證) and abnormal transmission to the pericardium(逆傳心包) were originally suggested by Ye Tianshi(葉天士). However, according to the findings of this study, these concepts are traced back to the contents of YB's publication, nearly a century before Ye's time. In addition, YB's discussion on '秋燥' was highly advanced than any other scholar of his time, hinting his influence on medicine thereafter.

Since just-in-time (JIT) has considerable overhead to detect hot spots and compile them at runtime, using sophisticated optimization techniques for embedded devices means that any resulting performance improvements will be limited. In this paper, we introduce a novel static Dalvik bytecode optimization framework, as a complementary compilation of the Dalvik virtual machine, to improve the performance of Android applications. Our system generates optimized Dalvik bytecodes by using Low Level Virtual Machine (LLVM). A major obstacle in using LLVM for optimizing Dalvik bytecodes is determining how to handle the high-level language features of the Dalvik bytecode in LLVM IR and how to optimize LLVM IR conforming to the language information of the Dalvik bytecode. To this end, we annotate the high-level language features of Dalvik bytecode to LLVM IR and successfully optimize Dalvik bytecodes through instruction selection processes. Our experimental results show that our system with JIT improves the performance of Android applications by up to 6.08 times, and surpasses JIT by up to 4.34 times.
