The regional security and stability in Northeast Asia has become more complicated because of a sudden establishment of China's Air Defense Identification Zone (ADIZ) on 23 November 2013. One dimensional conflicts on the territorial sovereignty over the islands between the regional States has developed into the two dimensional conflicts like maritime delimitations among the States concerned since they have all ratified the 1982 United Nations Convention on the Law of the Sea which adopts the 200 nautical mile Exclusive Economic Zone regime. Moreover, due to the notion of the outer limit of the continental shelf, the conflicts have developed into three dimensional ones in order to acquire more natural resources even in the seabed. To make matters worse, such three dimensional conflicts have expanded to the airspace as well. The paper will analyze what implications the sudden declaration of China's ADIZ have for the regional security in Northeast Asia from the perspectives of public international law. To this end, the paper 1) starts with the debates on the legal nature of the ADIZ, 2) identifies the Chinese government's political motives for the establishment of the ADIZ over the East China Sea, 3) assesses the responses of the regional States and the USA to the China's establishment of the ADIZ, and then 4) discuss what implications the overlapped ADIZ of the three key States in the region have for the regional security and stability.

With uniform heat generation within the wall of the cylinder placed in a cross flow, heat flows by conduction in the circumferential direction due to the asymmetric nature of the fluid flow around the perimeter of the cylinder. The circumferential heat flow affects the wall temperature distribution to such an extent that in some cases significantly different results may be obtained for geometrically similar surfaces. In the present investigation, the effects of circumferential wall heat conduction on local convective heat transfer is investigated for the case of forced convection around horizontal cylinder in cross flow of air. Two-dimensional temperature distribution $T_w$/(${\gamma}$,${\theta}$) is presented through the numerical analysis. The one-dimensional and two-dimensional solutions are in good agreement with experimental results of local heat transfer coefficients.

A general and efficient methodology has been developed to analyze dimensional variations of an assembly, taking into account of weld distortion. Weld distortion is generally probabilistic because of the random nature of welding parameters such as the welding speed, maximum welding temperature, ambient temperature, etc. The methodology is illustrated through a very simple example of two perpendicular plates fillet-welded to each other. Two steps comprise the methodology: establishment of a weld-distortion database, and tolerance analysis using the database. To establish the database, thermo-elasto-plastic finite element analyses are conducted to compute the weld distortion for all combinations of discrete values of major welding parameters. In the second step of tolerance analysis, the weld distortion retrieved from the database is used in addition to the dimensional tolerances of the parts. As a result of such an analysis, sensitivities of the assembly's dimensional variations to the part tolerances and weld distortion are obtained, which can be help improve the dimensional quality of the assembly.

본 연구는 2차원 PLS(Point Light Source) 배열과 디스플레이 장치의 조합을 통하여 시역형성용 광학판이 없는 3차원 영상을 재생하는 방법에 관한 것이다. PLS를 사용하여 3차원 영상을 디스플레이 하는 경우 기존의 시차장벽(parallax barrier), 렌티큘러(lenticular), 마이크로 렌즈(microlens lens) 등의 광학판을 사용할 때 발생하는 여러 가지 광학적 문제점 등을 해소할 수 있다. PLS로 사용된 LED 광원이 가져야 할 특성을 조사하였으며 PLS 배열을 통한 입체영상 디스플레이의 시역에 대해 실험을 통하여 입증 하였다.

These days, hair design is recognized as a kind of molding arts which peform expression skill to create personal self as well as practical skill. Recently, the efforts to express hair design sublimating it to art works have continued. For these reasons, this study had purposes as follows; First, it developed creative and original design producing works to shape the flower image that was an important material of hair design. Second, it presented the possibility to express the field of hair design with art. In the flow of age, nature has provided design with unlimited creative motive. Flowers, among various materials, show the nature's change, combination and order and impose diverse symbolic meanings. Therefore, flowers are good materials to express the works. Through the process of decolorizing and dyeing with hair, five works of nature's fragrance, hope, reed flowers, windflower, magnolia blossom had been produced. The results of the process were as follows; First, the transformation of shape through the simple process taking the image of shaping flower as subject matter could be a motive of new hair design art. Second, if the various images of flowers were expressed as hair art with three-dimensional shape, it could be works with value of beauty. Through the process of this study, it was proved that nature could be endless subject matter for art. Therefore, with continuous studies, it can be motive of developing designs in producing work activities of many hair designers. In addition, academic development will be achieved through wide and diverse studies.

This article analyses the concept of medicine in the legal context. It is not easy to define the concept of medicine because medical practice has various dimensions and the situation in which the practice is performed has a broad variety. The duty of medical law is to build the boundary of protection in that the nature of medicine would not be distorted by the factors of social systems like industry or governmental authorities. Without understanding the various dimensions - especially the dimension of Humanities and Sociology - of the medicine it is not possible to draw the limit on the performance of medicine appropriately. Concerning the medical practice (especially in the context of the regulation of medical licence), the enacted law (Medical Act) defines the concept just for form's sake and it finally depends on the interpretation of the legal enforcement authorities. Moreover, between the judgments of the courts there exists no coherent principles for the regulation and the interpretation of the Medical Act depends often on the riskiness, the abstract concept, which finally leads the interpretation to depend on the subject of the practice. On the contrary, the development and scientific movement of the technology tends to tighten the range of the medical professionals of medical practice and the perspectives of the medicine. Medical act is actually oriented at the patient's understanding of him- or herself. The above-mentioned tendency of the interpretation and the legal policy could lead the medicine away from its nature.

Estimating dimensions of attractors are the most basic tools to analyze properties of chaotical dynamic systems. In this paper, we estimate correlation dimensions of meteorological variables, such as wind speed (v) and temperature (T) observed in Kimhae International Airport when the land-sea breeze circulation is appeared and find low non-integer values that reflect the deterministic chaos characterizing the dynamics. We compare the results with the correlation dimensions of 2-dimensional model that is calculated by finite element method. Though the correlation dimensions of the calculated wind speed ( v) are less than those of the observed wind speed ( v), we can suggest that the land-sea breeze circulation has not a unique mechanism. The land-sea breeze phenomenon is a complicated dynamics, which is constructed with various scale motions of atmosphere. In further research, we hope to find more accurate dynamics of land-sea breeze through wide observations and using of more sophisticated prediction models.

We have investigated the coupling characteristics of localized modes of line defect i.e., guided modes, in photonic crystals. The parity of the coupled guided modes is not conserved when the distance between the line defects changes. By comparing the coupling characteristics of localized modes without the oscillatory nature such as cavity modes of metallic Fabry-Parot cavities with those of localized modes in photonic crystals, we confirmed that this parity nonconservation is attributed to the oscillatory nature of the evanescent waves of localized modes in photonic crystals.
