Computer game has become the core part of multimedia area in our knowledge and information based society Recently, computer game has been evolving into on-line 3D games which give players more realism from the existing on-line 2D games. We are competitive in developing on-line 2D games. However, we have difficulties in maintaining the competitive edge in the area of 3D game technologies owing to the limited technologies. In this paper, we design and develop Aria Online, an on-line 3D prototype game using Dream3D. The on-line game supports simultaneous connections of multi -users on each game server and full flexibility on user's view.

Dual channel Radiometer for Earth and Atmospheric Monitoring (DREAM) is the main payload on Science and Technology SATellite-2 (STSAT-2) of Korea. DREAM is two-channel microwave radiometer with linear polarization, and operating at center frequencies of 23.8 GHz and 37 GHz. An equation for DREAM calibration is derived which accounts for losses and re-radiation in the microwave components of the radiometer due to physical temperature. This paper describes the radiometric calibration equation to get antenna temperature ($T_A$) from the measured output data. At lower altitude, the measured deep space temperature is contaminated by middle atmosphere and earth radiation. In this paper, we presented the detail mathematical formulation to find the altitude up to which cold source brightness temperature is not affected by earth and middle atmosphere radiation. The DREAMPFM data is used to calculate the performance parameters (linearity, sensitivity, dynamic range, and etc.) of the system.

In order to understand the symbolic meaning of the dog in my dream more broadly, this paper aims to examine the symbolic meaning of the dog in various cultures and to understand the inner side in depth through such a process. Just as the growth of a person's character can be achieved through the conscious of the unconsciousness, looking at the contents of dreams made up of symbolic images is an important part of the growth of a person's character. In this paper, I first looked at the biological background of dogs and looked at various cultural symbols of dogs that appear in fairytales, myths, religions and folklore. Next, I reflected how Jung psychology looked at the symbol of the dog and finally discussed what the symbol of the dog in my dream had in the process of analyzing the dream.

Objectives : This study explores perspectives, reasons, functions of dreams in order to develop a treatment model. Methods : We searched CNKI, KISS, NDSL. Papers published since 2002, which are classified in categories. Results : 1. The Recognitions about the dream of Oriental Medicine is based on "Hwangjenaegyeong Eumsabalmong(黃帝內經 淫邪發夢)". 2. By each era, There are a variety of etiological causes, stages. 3. Dreams are generated by the internal stimuli Physiological activities of the Jangbu(臟腑),Deficiencies of yin and yang(陰陽), Pathological changes in the Jangbu(臟腑), Pathology products, external stimuli Yukeum(六淫), Eumsiksang(飮食傷), and unusual feelings. 4. Spirit(神) comes from brain(腦), not heart(心). So what we call brain spirit(腦神) is right. Dreams are the mental activity related to the brain. 5. Dreams are the reflection of the pathological changes of the human body. And it shows the development, changes and prognosis of disease. Dreams sometimes illustrate the incidence of the disease Conclusions : We organized perspectives, Causes and Functions of dreams mentioned in Oriental Medicine Literatures. Health is closely related to the dream. Therefore, we propose that the dream is worth for the diagnosis and treatment in oriental medicine.

Once upon a time people dreamt for a connected world. But most of the people consider dream as simple as a dream. But when this dream come into reality, the dreamer sometimes alive and sometimes not. But the later generations get outcome from the visionary dream of the former. This is the way of life. If we consider the whole world as a cyber physical system, if everything connects everything, how do we feel then? It is the smart Internet of things that may connect the whole world. This paper addresses few challenges and opportunities of this envisioned connected World. We identify different systems as cyber physical system and it ultimately contribute to the cloud infrastructure.

We examined the developmental characteristics of dream, daydream, and hope of elementary school students in their 1st, 3rd, and 5th grades, and studied the correlation between three variables. We summarized the results of this study as follows. 1) The contents of dream developed with the cognitive development and socialization process. In detail, appearance of animals, family members, and known persons gradually decreased, and appearance of self, same-sex peers, and strangers gradually increased. These results are comparable with the previous studies of dream. 2) Daydream, hope, and current state also developed with age. In detail, frequency of daydream increased, and the contents of daydream and hope changed toward more self-centered and more realistic. The changes of current state are thought to reflect the specific situation of Korea. 3) There are some correlation among dream, daydream, and hope. Especially happy mood and fearful mood had positive correlation with the relevant contents of dream, daydream, and hope. Also the contents of dream showed positive correlation with the same contents of daydream. This study is the first trial which investigate the developmental characteristics of dream, daydream, and hope of normal children in Korea. We verified that dream and daydream are on the continuous line of ‘reality-imitation-play-daydream-dream’ Finally, considering the facts that dream developed with age；responded to meaningful emotional experiences；and had the correlation with daydream, hope, and current state, the results of this study support the psychological meaning of dream.

The microwave instruments are used many areas of the space remote sensing and space science applications. The imaging radar of synthetic aperture radar (SAR) is well known microwave radar sensor for earth surface and ocean research. Unlike radar, microwave radiometer is passive instrument and it measures the emission energy of target, i.e. brightness temperature BT, from earth surface and atmosphere. From measured BT, the geophysical data like cloud liquid water, water vapor, sea surface temperature, surface permittivity can be retrieved. In this paper, the radiometer characteristics, system configuration and principle of BT measurement are described. Also the radiometer instruments TRMM, GPM, SMOS for earth climate, and ocean salinity research are introduce. As first korean microwave payload on STSAT-2, the DREAM (Dual-channels Radiometer for Earth and Atmosphere Monitoring) is described the mission, system configuration and operation plan for life time of two years. The main issues of DREAM unlike other spaceborne radiometers, will be addressed. The calibration is the one of main issues of DREAM mission and how it contribute on the space borne radiometer. In conclusion, the radiometer instrument to space science application will be considered.

The dream is a well-known experience in the routine life. It is necessary to consider the dream to modality of diagnosis because many evidences that the dream represents the physiologic and pathologic changes in the human have been proved in recent days. The oneironosus(病夢) was caused by three factors, which are the external stresses of the body, malfunction of Jang-Bu(臟腑) and irregular of Yin-Yang(陰陽) and Gi-blood(氣血). The oneironosus(病夢) reflects the location, characteristics, progression and prognosis of the disease. In addition, it predicts the development of disease. The principle of treatment for the oneironosus(病夢) is making an effort for the stabilization of mind by eradicating the internal and external factors that make the spirit(神) been unstable.
