The continuum elasticity model is applied to investigate quantitatively the growth features and nucleation mechanism of quantum dots, nanopits, and joint QDs-nanopits structures in GaInAlN quasyternary systems. We have shown that for GaInAlN material system at the critical strain of ${\varepsilon}^*=0.039$ the sign of critical energy and volume is changed. We assume that at ${\varepsilon}={\varepsilon}^*$ the mechanism of the nucleation is changed from the growth of quantum dots to the nucleation of nanopits. Obviously, at small misfit (${\varepsilon}$ < ${\varepsilon}^*$), the bulk nucleation mechanism dominates. However, at ${\varepsilon}$ > ${\varepsilon}^*$, when the energy barrier becomes negative as well as a larger misfit provides a low-barrier path for the formation of dislocations, the nucleation of pits becomes energetically preferable. The free energy of mixing for $Ga_{1-x-y}In_xAl_yN$ quasiternary system was calculated and studied and its 3D sketch was plotted.

The protonation parameters, dissociation constants ($pK_{BH^+}$) of conjugate acid, slope values (m, ${\phi}$ and $m^*$) and correlation coefficients (r) of hydroxamic acids were determined by Hammett acidity function method, Bunnett-Olsen method and excess acidity method in hydrochloric and perchloric acid solutions. Effect of acid concentration on partition and percentage protonation was also studied. $pK_{BH^+}$ values show that hydroxamic acids do not behave as Hammett bases, but hydroxamic acids behave as weak bases in strong acidic solutions. The values of $pK_{BH^+}$ obtained through Bunnett-Olsen method and excess acidity method were compared with the Hammett acidity function. ChemAxon's MarvinSketch 6.1.5 software was also used for determining $pK_a$, pI and microspecies distribution (%) of hydroxamic acids with pH. Hydrogen donor and acceptor values and logD were also obtained. The results show that N-p-chlorophenyl-4-bromobenzohydroxamic acid has the highest $pK_a$ and lowest logD values. On the contrary, N-phenyl-3,5-dinitrobenzohydroxamic acid has lowest the $pK_a$ and highest logD values.

Recently, generative adversarial networks (GANs) is a field of research that has rapidly emerged wherein many studies conducted shows overwhelming results. Initially, this was at the level of imitating the training dataset. However, the GAN is currently useful in many fields, such as transformation of data categories, restoration of erased parts of images, copying facial expressions of humans, and creation of artworks depicting a dead painter's style. Although many outstanding research achievements have been attracting attention recently, GANs have encountered many challenges. First, they require a large memory facility for research. Second, there are still technical limitations in processing high-resolution images over 4K. Third, many GAN learning methods have a problem of instability in the training stage. However, recent research results show images that are difficult to distinguish whether they are real or fake, even with the naked eye, and the resolution of 4K and above is being developed. With the increase in image quality and resolution, many applications in the field of design and image and video editing are now available, including those that draw a photorealistic image as a simple sketch or easily modify unnecessary parts of an image or a video. In this paper, we discuss how GANs started, including the base architecture and latest technologies of GANs used in high-resolution, high-quality image creation, image and video editing, style translation, content transfer, and technology.

Various walking robot platforms have been developed to carry out missions such as explorations, pass of obstacle or inspections of dangerous environments. In this work, a four legs mechanism based on Jansen mechanism is developed, which can follow a certain track and overcome obstacles. To find the ideal locus, computer programs are used such as M. sketch and Working model. Using these program tools, moderate linkage sizes are selected in Science Box. Furthermore, in order to optimize design of legs, a level average analysis is used as well as Edison S/W. Through the design optimization, improved stride of locus is found.

Walking mechanism, there are many types. Prior to the modeling and design, we thought about a variety of mechanisms based on the Janssen mechanism to design a walking mechanism optimized for walking. The more the legs increases the stability of the structure, while the weight is heavy and if that advantage had the disadvantage, the legs are easier to walk in the utilization and structural aspects of the torque had fewer advantages. The disadvantage is that the instability mechanism, four-legged, but improve it and look forward to the idea of utilization and cost-effectiveness, its future utilization will be endless. To study this, we utilized a variety of software, such as m-sketch, Edison design program, we have seen the actual production through scientific experiments box.

These days the copyright plays a significant role in various fields of creative works and it has expanded dramatically into unprecedented ways. In Korea, architectural works copyright cases are rare due to the lack of information and understanding of the architectural works copyright. Architectural works copyright can promote architects' creative activities and enhance the quality of architectural works as art. Nevertheless, there is little effort to advance the studies of architectural works copyright in the architectural design area. Under these circumstances, this research attempts to share the basic case laws and remedies for various architectural works copyright issues in the U.S. cases. This Article examines the Thomas Shine v. David M. Childs and Skidmore Owings & Merrill, LLP Case which is the most recent case as I could reach. This case is about a story between two architects, one is from a very prestigious architectural design firm and the other, once Yale Architectural student, now practices his design work as an up-and-coming architect. A close examination of this case will provide a legal and architectural spectrum of copyright. That is, it will make it more specific how to solve the copyright infringement. Artistic and technological contexts are overlapped in Architectural works copyright as its inherent characteristics. Therefore, different ways from other copyrighted works are needed to access the untangled equations of the architectural works copyright protection. In addition, more comprehensible and specific regulations that can impose a remedy more suited to the architectural works copyright violations are needed and they should enable architects to fulfill their architectural activities under wide range of copyright protection. Moreover, in prior to all efforts to handle those equations, fundamental knowledge of architectural works copyright is required to improve the copyright protection in the architectural design area as well as to provide for the globalizing design practice. Ultimately, all of these efforts will be rewarded when constant researches based on Korean and other countries' architectural copyright cases can support them and it would be great if this research can set the stage for resolving expected copyright conflicts within the architectural design area.

독일인 지질학자 카를 곳체(C. Gottsche)는 1884년 당시 조선의 통리아문 협판이던 묄렌도르프의 초청을 받아 한반도 내륙을 조사하였다. 그는 138일에 걸쳐 2,550km의 거리를 주파했는데, 귀국 후 당시 답사 자료를 바탕으로 조선의 지리와 지질에 관한 3편의 논문을 발표하였다. 이 논문들은 근대 지리학과 지질학을 정식으로 훈련을 받은 야외과학자가 한반도 전역을 실제로 답사하고 쓴 우리나라 최초의 근대적 지구과학 논문이라는 점에서 의미가 있다. 그가 쓴 3편의 논문 중에서 특히 "조선의 지리(${\ddot{U}}ber$ Land und Leute in Korea)"(1886)는 조선의 지질과 광물에 주목한 다른 2편의 논문과는 달리, 야외과학자의 눈에 비친 조선의 모습이라는 점에서 이 논문이 지닌 사료적 가치도 높다. 이 논문은 아직 국내 학술논문에 소개된 바 없어 19세기 말 서구인들의 조선 인식을 이해하는 데 도움이 되는 사료이자, 우리나라 최초의 근대적 지리학 문헌이다.
