Total fertility rate in South Korea is the lowest in the world. A fertility rate below replacement fertility level will result in serious social problems in the long term. Therefore, it is worthwhile to study a general understanding about the low fertility rate phenomenon and to investigate the effectiveness of fertility policies in order to ameliorate the resulting social problems due to the low fertility rate. This research was a descriptive examination into the low fertility rate phenomenon and an investigation of the needs for fertility potties and their effectiveness. The study subjects were consisted of 769 unmarried people aged from 18 to 40 years old. Data were collected from June to August 2004 and were analyzed by frequencies, mean, and standard deviation. The following results were revealed. First, unmarried people in general had positive perspectives about getting marriaged, giving birth, and being a parent. In addition, the primary cause of low fertility rate was economical difficulties for raising a child. Third, unmarried people thought that the low fertility rate phenomenon resoled in both positive and negative changes in a society. Fourth, policies for economical supports for raising children, establishing social atmosphere for gender equality, and trustful public educational systems were the political alternatives that people really wanted for having a child in the future. Effective alternatives for policies and strategies to address the low fertility rate problems are suggested in the discussion section.

With supplied computers and the development of information and communication thropugh the Internet, the space of personal home pages in potal sites has been filled with photos taken by digital cameras, and 'the introduction of privacy' done in the personal home pages has become a general trend in society. As the use of Photoshop, available to edit and modify digital photos, in this social atmosphere, has grown general, they have shown their interest in the retouching technique of Photoshop. Computer graphics, marked based on the treatment of a variety of information into pictures or a technology to mark it, recently various application methods have been found in make-up. Especially, Adobe Photoshop, used to edit and modify images, is a sofetware program proper to perform beauty make-up in correcting and creating images in an effective way. The purpose of this study is to express each factor in Adobe Photoshop CS2 about the beauty make-up. As a result, I can say, the process that digital image is retouched by Adobe Photoshop CS is similar work to beauty make-up. The process of Photoshop retouching can be used as the materials for educating of make-up and as the materials for presentation of beauty make-up trend. And also we can serve the simulation to the customer before real make-up. Therefore, this study is for the effective performance of diverse beauty makeup integrating retouch technique with Photoshop CS.

In the 20th Century, the genera1 hospitals in Korea had changed in Qualitative and Quantitative aspects, The former would include such as the development of medical skills, equipments, and network system, The expansion of hospital space, increased numbers of hospitals and greater demands of medical attention from the public would be included in the latter, These various changes have been related to external forces such as the growth of the population, the changes in medical policy, the growth of G.N.P, the continuing discovery of new illnesses, the changes in architecture policy, and et cetera. Particularly, the hospitals built in 1970's and 80's have been expanded and renovated to cover the shortage of space, aged facilities, and the changes in hospital atmosphere. Thus, we hope that this study would provide appropriate data for master plans for new medical facilities as well as expansion and renovation data for old ones.

The sensitivity of the extratropical jet to the stratospheric mean state is investigated by conducting a series of idealized numerical experiments using a dynamic-core general circulation model. When the polar stratosphere is forced to be cold, the extratropical jet, defined by the 850-hPa zonal wind, tends to shift poleward without much change in its intensity. The opposite is also true when the polar stratosphere becomes warm. This jet response, however, is not exactly linear. A poleward jet shift under a cold vortex is much weaker than an equatorward jet shift under a warm vortex. The jet intensity change is also larger under a warm vortex. This result indicates that the stratosphere-troposphere downward coupling is more efficient for the warm and weak polar vortex. This finding is consistent with a stronger downward coupling during stratospheric sudden warming than vortex intensification events in the Northern Hemisphere winter, possibly providing a clue to better understand the observed stratosphere-troposphere downward coupling.

Among the weather conditions on the Korean Peninsula, Changma is a notable phenomenon. This is because substantial amount of the precipitation on the Korean Peninsula tends to happen during the Changma season. But there are times when this tendency falls into whims. That's the case when it doesn't rain or rains only little during the Changma season. The Korea Meteorological Administration (KMA) describes this phenomenon as 'Dry Changma' - meaning . However, 'Dry Changma' is often regarded as an instance of contradicto in adjecto. Since the general public believe that 'Changma' means . This confusion often leads to distrust in meteorologists. In this paper, we would like to propose a reasonable solution to this conundrum by employing the conceptual resources of contemporary philosophy. First of all, I will make explicit the meaning of 'Changma' that the public and meteorologists think of. And then a brief explanation of the concept of natural kinds will be presented and the argument will be made that Changma is a natural kind. Next, we will discuss a view on natural kind terms advanced by Saul Kripke, a renowned philosopher. We will argue that in Kripke's view, the general public's thought that 'Dry Changma' is contradicto in adjecto is not correct. This will eventually lead to the conclusion that the meteorologist usage of 'Changma' is the correct one, which is thereby to be adopted by the public.

Plasma is generated by electrical discharge. Most plasma generation has been carried out at low-pressure gas typically less than one millionth of atmospheric pressure. Plasmas are in general generated from impact ionization of neutral gas molecules by accelerated electrons. The energy gain of electrons accelerated in an electrical field is proportional to the mean free path. Electrons gain more energy at low-pressure gas and generate plasma easily by ionization of neutrals, because the mean free path is longer. For this reason conventional plasma generation is carried out at low pressures. However, many practical applications require plasmas at high-pressure. In order to avoid the requirement for vacuum pumps, researchers in Korea start to develop plasmas in high-pressure chambers where the pressure is 1 atmosphere or greater. Material processing, environmental protection/restoration and improved energy production efficiency using plasmas are only possible for inexpensive bulk plasmas. We thus generate plasmas by new methods and plan to set foundations for new plasma technologies for $21^{st}$ / century industries. This technological research will play a central role in material processing, environmental and energy production industries.

The Korean hospitals have been changed a lot from 1970's to 1990's, not only in their space allocation but also in their functions. These changes were affected by the medical development, social atmosphere, increasing population, needs of medical demands, and so on. In this study, we compared net area allocation involve in these affect of hospitals which were built in 1970's, 80's, and 90's, and through this comparison, we analyzed developing tendencies of hospitals. In doing so, we tried to provide basic research data for planning of new hospital buildings.

In "EuiMoonBubRyool" chapter 4, Yuchang criticized previous doctors since "damaged by wet in autumn" written in "Somun" must be corrected as "damaged by dry in autumn". The reason why the sentence must be corrected is that dry and damp are different atmosphere. He tried to explain with changes of season and the rapid pulse in autumn is said to be a contraindiction in "Naekyung" and it supports Autumn dry theory. He criticized previous doctors about many incorrect points of dry disease throu호 various aspects. Criticism on Dongwon's treatment, Dangye's medical theory and not having a treatment, and Mujungsoon's treatment and etc. are the examples. Symtoms and treatment of Dry disease that Yuchang commented helped in deepening the contents and widening the general understanding of the disease.

The atmospheric flow in the 3-Cell model of global atmosphere circulation is described by the Lagrange's equation of the non-inertial frame where pressure force, frictional force and fictitious force are mixed in complex form. The Coriolis force is an important factor which requires calculation of fictitious force effects on atmospheric flow viewed from the rotating Earth. We make new Mathematica platform to solve Lagrange's equation by numerical analysis in order to analyze dynamics of atmospheric general circulation in the non-inertial frame. It can simulate atmospheric circulation process anywhere on the earth. It is expected that this pedagogical platform can be utilized to help students studying the atmospheric flow understand the mechanisms of atmospheric global circulation.

Even though state-of-the-art general circulation models is improved step by step, the seasonal predictability of the East Asian summer monsoon still remains poor. In contrast, the seasonal predictability of western North Pacific and Indian monsoon region using dynamic models is relatively high. This study builds canonical correlation analysis model for seasonal prediction using wind fields over western North Pacific and Indian Ocean from the Global Seasonal Forecasting System version 5 (GloSea5), and then assesses the predictability of so-called hybrid model. In addition, we suggest improvement method for forecast skill by introducing the lagged ensemble technique.
