The change in the magnetic properties of a spin-valve multilayer with the structure IrMn (9 m)/CoFe (4 nm)/Cu (2.6 nm)/CoFe (2 nm)/NiEe (6 nm) is investigated as a function of the size and the aspect ratio. At a fixed aspect ratio (the length/width ratio) of 2, the magnetostatic interactions begin to affect the magnetic properties substantially at a spin-valve length of 5 $\mum$, and, at a length of 1 $\mum$, they become even more dominant. In the case of a fixed multilayer size (2.4 $\mum$) which is indicated by the sum of the length and the width, magnetization change occurs by continuous spin-reversal and M-H loops are characterized by no or very small hysteresis at aspect ratios smaller than unity, At aspect ratios greater than unity, magnetization change occurs by spin-flip resulting in squared hysteresis loops. A very large changes in the coercivity and the bias field is observed, and these results are explained by two separate contributions to the total magnetostatic interactions: the coercivity by the self-demagnetizing field and the bias field by the interlayer magnetostatic interaction field.

Spatial and temporal patterns of precipitation and temperature occur with regard to aspect and elevation of Mt. Halla in Jeju Island. Therefore, there is a need to predict regional drought associate with them to mitigate of impacts of drought. In this study, regional drought is predicted based on Palmer drought severity index (PDSI) and standardized precipitation index (SPI) using future (2015~2044) climate change scenario RCP (representative concentration pathways) 4.5 classified as 24 regions according to aspect and elevation. The results show that number and duration of drought will be decrease in Jeju Island. However, severity of severe drought will be increase in western and northern aspect with under 200 meters above mean sea level. These findings provide primary information for developing the proactive strategies to mitigate impacts of drought by future climate change in Jeju Island.

This study shows historical Gagye(가계) The process of change and Characteristics through analysis on the old documents, related papers, and visual data, and represents its meaning in Korean Clothing history through analysis on originality of Korean Gagye(가계) style. Gagye(가계) is the cubic hair style which add other accessories on hair and is divided into two; Gagye(가계) and Chegye(체계) according to its material, role, and function. And Korean Gagye(가계) has been transformed suited to the times and showed various features according to pattern, wearing, and decoration aspect. In its style aspect, Korean Gagye(가계) style shows Hwangye type, Sseugae type, Gogye type, Dagye type, and Braided & coiled hair type. Each shows historical features. In its Wearing aspect, Gagye(가계) style shows Wearing ornamental hairpin on the head, Wearing Rag Ribbon on the head, and Attaching (Detaching) Wearing. And in its Decoration aspect, Gagye(가계) style shows decoration with accessories, one with flower arrangement, and one with shaking.

In this paper, I seek to differentiate the meaning of the auxiliary verb '-e ka-' from imperfective aspect in Korean. The progressive in imperfective is expressed by the 'be+V-ing' in English and '-ko iss-' in Korean. However the '-e ka-' in Korean can express the gradual progress meaning. This is similar to the progressive of some state verbs. These verbs cannot express the progressive aspect but it is possible if they can express the change of state in sentence. It is more corresponding to the '-e ka-' than '-ko iss-' in Korean.

The service oriented architecture assures flexibility of enterprise application development, so it supports agile reaction to business change. On the other hand, considerable effort is needed to develop a service by combining business and constraint consumes because the entire combination logic should be changed according to the change in business rule. To improve the current method, this paper applied an aspect oriented approach to service system development. In this paper, the rule concern is proposed in addition to the core concern and cross cutting concern of aspect oriented approach. The rule concern is extracted from business rules included in the business processes and services. The rule concern is classified into the process rule aspect and service rule aspect according to the level of the rule. In the proposed approach, system is modularized into the core concern, cross cutting concern and rule concern through separation of concern, and they are maintained independently. Therefore, the adaptability, reusability, and maintainability of a service system will be enhanced.

Objectives : The Phrase, Ki goes to Essence and Essence goes to Change in Eumyangeungsangdaeron in Suwen have contradiction in direction of Ki. Because this phrase linked to relation of Taste, Shape, Ki, Essence and Change, each others are supposed to be treated systematically. Methods : We will review on annotations of past doctors and new opinions of resent scholars. Results : Ki has two meanings in this phrase ; Ki of food and Ki of ability in human nature. Conclusions : From the Taste through Shape to Ki of food are the way of Eum aspect and from the Ki of ability through Essence to Change are the way of Yang aspect.

At the product design and development stage, the main criteria selecting a design alternative were performance aspect as well as cost aspect of a product. Ongoing new paradigm shifts such as low carbon green growth, climate change mitigation, sustainable society development urged considering environmental aspect of a product at the product design and development stage. Up to recently, only cost aspect except performance of a product was considered at the railway vehicle design process. Therefore, it is needed to develop a method that may consider environmental aspect of a product at the railway vehicle design process. Lee (2011) proposed that a method of an integration assessment of environmental aspect and cost aspect based on GHG emission instead of based on monetary value. This study conducted that apply the method of Lee (2011) to design alternative selection process of a railway vehicle. From the integrated view of environmental and cost aspect, the reference product and design alternatives are assessed and compared.

A Gangwon region consisting of over 80% of forest area has industries that have been developed by utilizing its clean region image. However, the recent climate change has increased the forest disease & insect pest as well as the forest fire and the major cause is known to be the increase in the frequency of a drought occurrence. From the aspect of climate change, it can be said that drought and forest are important in every aspect of the adaptation and mitigation of climate change measure as they increase forest disease & insect pest that leads to desolation of usable forest resource. In addition, the increase of forest fire reduces resources that can absorb greenhouse gas, which leads to increase in green house emission. The purpose of this study is to provide a motive for concentrating administrative power for protecting forest in a Gangwon region by selecting a drought management needed local government through a drought forecast according to the climate change scenario of a Gangwon region.

The atomizations of CWM slurry and water are done by a wheel atomizer which is designed and manufactured for this experiment. The variables of the experiment are the angle of vane, aspect ratio, particle loading and the mean size of coal particle distribution. The main purposes of the experiment are to know how the angle of vane and aspect ratio of vane influence the size distribution of CWM droplets. The experimental results say there are no appreciable effects on the mean size of CWM droplets from the change of loading of coal prticles in slurry. The mean size of coal particle in slurry, however, influence quite strongly the mean size of CWM droplets. The mean size of CWM droplets is quite strongly affected by the angle of vane. The size distribution of CWM droplets is controllable by the change of aspect ratio.

This study is focused to predict the behavior of Al foam with closed-cell structure during the 3 point bending test and the upsetting test according to aspect ratio. We calculated characters of aluminum foams with closed-cell structure and took the simulation. The effects on the aspect ratio of the cell was investigated parametrically. The analysis was carried out on two models, First, the bending test in elasticity of the rectangular beam, and Second, the upsetting test in plasticity of the circular cylinder. In the analysis, the deformation of the beam and the cylinder was influenced by the aspect ratio of the cell. Further, We assumed that the geometry of feared aluminum cell change the stress and strain in the test.
