The purpose of this paper is to discuss the impact of the New Container Security Initiatives of U.S., CSI(Container Security Initiative) and C-TPAT(Customs-Trade Partnership against Terrorism). The CSI which aims to pre-screen high-risk containers in ports of loading. It is a unilateral effort that seeks to develop bi-lateral agreements between the United States and foreign countries with significant container trade volumes into the U.S. C-TPAT is a voluntary initiative to develop cooperative security relationships between the U.S. government and U.S. firms in the global supply chain. Government and Industry have already responded with proposals to create more confidence in supply chain security. These proposals call for heightened inspection and scrutiny of the goods flowing through a supply chain, increased information exchange among participants of supply chain. While government and the private sector are working together to launch new initiative to create more secure and reliable supply chains, industry is rapidly exploring the potential of new technologies such as RFID. The security recommendations will eventually become the requirements to be complied with by importers and their supplier extending to the carriers. It is needed that Korean shippers involved in US importer's supply chain should pay attention to the requirements and start implementing the security measures.

Let G be a simple undirected graph. A planar graph known as a Halin graph(HG) is characterised by having three connected and pendent vertices of a tree that are connected by an outer cycle. A subset S of V is said to be a dominating set of the graph G if each vertex u that is part of V is dominated by at least one element v that is a part of S. The domination number of a graph is denoted by the γ(G), and it corresponds to the minimum size of a dominating set. A dominating set S is called a secure dominating set if for each v ∈ V＼S there exists u ∈ S such that v is adjacent to u and S₁ = (S＼{v}) ∪ {u} is a dominating set. The minimum cardinality of a secure dominating set of G is equal to the secure domination number γ_s(G). In this article we found the secure domination number of Halin graph(HG) with perfet k-ary tree and also we determined secure domination of rooted product of special trees.

In Korea-U.S.A. FTA Negotiation, U.S.A. request to eliminate barriers of tariffs and non-tariff in trade of cosmetics. Korea applies tariffs of 8% on most cosmetics and personal care products. There are some non-tariffs barriers in cosmetics trade between Korea and U.S.A., for example, transparency on restriction and regulatory, cosmeceuticals, import clearance review, quality control testing, ingredient labelling. Tariffs of 8% on most cosmetics should be eliminated, a proviso of complementary measures on sanitation of Korean people about imported cosmetics. This is a meaning of reformation of prior management(tariffs) by strong ex post management in cosmetics trade. It is important that Korea should construct system of ex post management, for instance, construction of data base on manufacturer, importer, bland name of cosmetics and all ingredients of cosmetics. This is concerned with labelling of cosmetics and cosmeceutical and publication of Korean edition of INCI(International Nomenclature of Cosmetic Ingredient).

We study bifurcation for the following fractional Schrödinger equation $$\{\left.\begin{eqnarray}(-{\Delta})^su+V(x)u&=&{\lambda}f(u)&&{\text{in}}\;{\Omega}\\u&>&0&&{\text{in}}\;{\Omega}\\u&=&0&&{\hspace{32}}{\text{in}}\;{\mathbb{R}}^n{\backslash}{\Omega}\end{eqnarray}\right$$ where 0 < s < 1, n > 2s, Ω is a bounded smooth domain of ℝⁿ, (-∆)^s is the fractional Laplacian of order s, V is the potential energy satisfying suitable assumptions and λ is a positive real parameter. The nonlinear term f is a positive nondecreasing convex function, asymptotically linear that is $\lim_{t{\rightarrow}+{\infty}}\;{\frac{f(t)}{t}}=a{\in}(0,+{\infty})$. We discuss the existence, uniqueness and stability of a positive solution and we also prove the existence of critical value and the uniqueness of extremal solutions. We take into account the types of Bifurcation problem for a class of quasilinear fractional Schrödinger equations, we also establish the asymptotic behavior of the solution around the bifurcation point.

The-state-of-the-art of rice drying in the U.S.A. is presented. The U.S.A. is a minor producer but major exporter of rice. Head yield is its major criterion in evaluating rice quality . A decrease of 1 to 3 points in head yield can be expected to occur in a well-designed rice-drying system. Rice is dried on the farm in bins in the U.S. A., and n high-temperature continuous -flow dryers at the elevator level. Two relatively new rice-drying systems are discussed in some detail. : The top-bin/in -bin-counterflow bin-type on-farm dryer, and the concurrent-flow high-temperature elevator dryer.

The fall accidents have been occurred continuously although the efforts to prevent fall accidents have been made constantly. On the other hand, the U.S.A executes the policy improvements and various prevention system then, as a result, the fall accidents of the U.S.A. construction industry are greatly decreased. Therefore, the objective of this study is to investigate the causes and prevention system regarding fall accidents between South Korea and U.S.A. The findings of this study can be utilized to decrease fall accidents of South Korea as a basic material.

The estimation of the undrained shear strength $s_u$ for clays using CPT results has been mainly based on the cone factor $N_k$. In this study, a new CPT-based method for the estimation of the undrained shear strength $s_u$ is presented. This aims at reducing uncertainties for the estimation of $s_u$ and enhancing the application of CPT results in more effective manner. For this purpose, a site located at a marine clay deposit is selected and test results from extensive experimental testing program are adopted. The new method defines a direct correlation between the undrained shear strength $s_u$ and the cone resistance $q_t$, excluding the procedure of the overburden pressure correction and therefore undisturbed soil sampling process. In order to verify the new CPT-based method, additional test sites and example sites from literature, which consist of a variety of soil conditions, are selected and examined. It is observed that values of su obtained from the proposed method are in good agreements with measured values of $s_u$ for all the selected verification cases.

Since long ago, "The Discourse of Confucius" has been considered as one of the must-read classical literatures in the world of art. The term Huì-shì-$h{\grave{o}}u-s{\grave{u}}$ (繪事後素) in this literature is not only known by the painter but is also known to anyone who discuss about pictures. However, there is a great diversity of interpretation between its meaning of "drawing a picture is done when its basis is ready" or "drawing a picture is done later when completed with white color". The method of drawing does not change much with time. Scholars usually consider professional paintings conventional and don't understand well the white characteristics of the painting technique. In any case, it is basic to deal with the basis before drawing but completing the picture, finishing with white is not so common. Paintings from ancient times are not so different from today's silk pictures. Because Huì-shì-$h{\grave{o}}u-s{\grave{u}}$(繪事後素) fostered the attainments being the basis of life and the artistic sense, it remains as the aesthetics to many artists. The interpretation of Huì-shì-$h{\grave{o}}u-s{\grave{u}}$(繪事後素) is related to the change with time in 'The theory of courtesy(禮論)' but this study focused purely from the artistic point of view.

I found following idea, as a result of researching his Science idea, mainly, by translation of the "$Zh\bar{a}ng$ xi $ch\acute{u}n$ $Xu\acute{e}$ $Sh\acute{u}$ ssu $hsi\acute{a}ng$ "(張錫純 學術硏究). $Zh\bar{a}ng$ xi $ch\acute{u}n$ regarded $ch\tilde{u}ng$ $ch\bar{u}ng$ $ts'\bar{a}n$ $hs\bar{l}$' (衷中參西) as the core idea of The Chinese-Western medical combination. He didn't segregate philosophy of the West from One of the Orient. He persued to harmonize each other and thought that the Western medicint theory is included in the Chinese one in many parts. besides, He recognized that it is bad to reject each other, for the medical science's purpose is to save a life, and united The Chinese-Western medicine theory, by $ch\acute{u}ng$ $ch\tilde{u}ng$ $ch\bar{u}ng$ $ts'\bar{a}n$ $hs\bar{l}$'(衷中參西) idea which refers to consult the Western medicine on the basis of the Chinese one. Medical basic theory of $Zh\bar{a}ng$ xi $ch\acute{u}n$ brought up new views of the theory : Dae-gi(大氣), gi-Hwa(氣化) theory, Nongangubgan byung juing chi(論肝及肝病證治), Eum her chijung ja bi(陰虛治重滋脾). Lim Sangeung yong(臨床應用) of Hyul Her gub(血虛及)-Hwal Hyul Hwa $\breve{u}$ bub(活血化瘀法), on the basis of classics, such as, "$N\breve{e}i$ Ching"(內經), "Chin Kue $\breve{i}$ $y\bar{a}o$ $l\ddot{u}{\bar{e}}h$, "Shen $n\acute{u}ng$ $p\breve{e}n$ $t\acute{s}{\check{a}}o$ ching"(新農本草經) etc. I'll sum up $Zh\bar{a}ng$ xi $ch\acute{u}n's$ clinical idea now He unified Sang Han(像寒)-On Byung(溫病) with Yuk Kyung Byung Jung(六經辨證) and It was noticiable to utilize a kinds of Baek Ho Tang(白虎湯). He gave a detailed description about a method of grasp the symptoms of the cause of the internal medicine diseases and pathology and, he left abundant views of theory about using remedy and experience of clinic.
