`Sansinkak' is the building which contains the picture or statue of mountain god(=Sansin). It is also an expression of respect for the mountain god. This building is usually very small, so a few person can enter inside it. Because people pray to mountain god for personal purpose, sometime this wishes are exclusive and egoistic, so narrow space is more suitable. Sansin is not the original god of Buddhism, it is the god of folk belief of traditional Korea, so every Sansinkak is located in the back slope of the temples, away from Buddha's building, the center area. Sansinkak is not only the pathway of vital force from back mountains to the temple, but also the exit to the infinite nature as an extension of Buddhist belief.

SFF(solid freeform fabrication) is another name of RP(rapid prototyping). The SFFS for office type wishes to develop system that can produce small object such as hand phone, cup, accessory etc. with high speed, and also intend suitable system in office environment by compact design, and buy easily by inexpensive price. As can manufacture high speed in existent SFF process technology, representative process that have competitive power in price is 3DP (three dimensional printing) technology. The 3DP technology is way to have general two dimensional printing technology and prints to three dimension, is technology that make three-dimensional solid freeform that want binder doing jetting selectively on powder through printer head. We designed and manufactured SFFS for office based on 3DP process technology design and manufactured, and composed head system so that use 3 printer heads at the same time to improve the fabrication speed of system. We used printer head of INCJET company and cartridge used HP45 series model who can buy easily in general city. And we directly fabricated three dimensional solid freeform using developed SFFS for office type.

Modern house degraded by object of possession by industry and capitalistic development, and it is losing genuine meaning as order system to secure perpetuity of dwelling. Paradigm of space embodiment need first of all laying stress on human's life to overcome such modem dwelling crisis. In modern age Europe, Adolf Loos tried to embody residing space of human center within modernistic developing of technology, urbanization etc.. For such reason, Raumplan is worth reviewing. By treatise that research about Raumplan is many already presentation of the results of ones study do. But most discussions were limited by opinion which is 'Three-dimensional space plan techniques' that give attention to in physical characteristics of Raumplan, and by opinion which is 'Adolf Loos' criticism about culture with outside society. We reconsidered Raumplan in side of general paradigm of residing space embodiment that started from relevant resident's life in treatise that see as such reason. As a result, we knew that is near in residing space original target that Raumplan wishes to embody human's life to space, and this nowaday suitable candidate for marriage as excellent thanks for residing crisis conquest of done situation quote may.

People's Interest about culture is increasing to reach in today's knowledge based society on age of modern industrial society. Conversion of human based idea arrived in step that human through scientific technique development such as life reproduction approaches gradually in God's sacred ground. Evolution of human's culture was proceeded slowly in current of such radical change.Life underestimate, religion war, pollution etc. are seeming to keep away human development.This treatise wishes to redefine concept of suitable culture in new terminology of 'SeaCricle' that have characteristic of water at 21C's New Age.

In this paper, we present a real-time physical simulation model of water surfaces with a novel method to represent the water mass flow in full three dimensions. In a physical simulation model, the state of the water surfaces is represented by a set of physical values, including height, velocity, and the gradient. The evolution of the velocity field in previous works is handled by a velocity solver based on the Navier-Stokes equations, which occurs as a result of the unevenness of the velocity propagation. In this paper, we integrate the principle of the mass conservation in a fluid of equilateral density to upgrade the height field from the unevenness, which in mathematical terms can be represented by the divergence operator. Thus the model generates waves induced by horizontal velocity, offering a simulation that puts forces added in all direction into account when calculating the values for height and velocity for the next frame. Other effects such as reflection off the boundaries, and interactions with floating objects are involved in our method. The implementation of our method demonstrates to run with fast speed scalable to real-time rates even for large simulation domains. Therefore, our model is appropriate for a real-time and large scale water surface simulation into which the animator wishes to visualize the global fluid flow as a main emphasis.

VPN can give safety in connection in Timbuc-too, by corporation's basis communication means today that transfer user support in Timbuc-too is required compulsorily, VPN is activated. This research wishes to investigate base technology of VPN software field and investigate VPN software market trend and standard and develop estimation model of VPN software. For this special quality of VPN software investigation / analyze and investigate or analyze market trend and standard this to VPN software to base deduction of estimation item and estimation model develop.

The reconstruction of major head and neck defects must be an integral part of the overall cancer treatment plan. The priorities of surgical treatment of head and neck tumor are 1) local tumor control, 2) relief of pain, 3) avoidance of difficult dressing, 4) provision of oral continence, and 5) ability to swallow and manage saliva. The recent advances in reconstructive surgery including the development of musculocutaneous flaps and microvascular free tissue transfer have allowed the surgical restoration of head and neck tumor defects that previously were not possible. These techniques have provided the opportunity to undertake larger, more aggressive resection while at the same time permitting functional rehabilitation. The timing of reconstruction demands on the nature of the resection, the ability of the ablative and reconstructive teams to coordinate efforts, the overall health of the patients, the patient's needs and wishes. So, we report to emphasize current methods for restoring major head and neck tumor defects after tumor ablation, reviewing for the reconstructive operations, postoperative complications, and postoperative sequelae etc, of patients from Jan, 1990 to Dec, 1993.

Many closed schools of about more 3,000(2006 year) have occurred all over the country according to governmental policy of 1982. These closed schools were sold or rent to institution, local government, and a private, and are used by various usage such as novitiate, institution, educational facility, art creation facilities, warehouse, and factory. But, unimproved closed school facilities are still reaching for about 450. Among practical use example of such closed school, alternative educational facility, practice facilities, art creation facilities etc. with closed schools which have general surrounding natural landscape and environment uses well preserved were applied consciousness and the practice about environmental problem to ecological concept. Also, a lot of discussions about ecological concept and study for desirable solutions about practical use of closed schools example have been achieved. However, it is hard to find various ecological practical use examples at filed. In such background, this research wishes to investigate changing space and facilities variously and its usage which is applied ecological concept with regional closed schools.

Recently 'Banking IC Card Standard' and EMV Standard by the domestic standard is selected, and it is situation that is developing infrastructure vigorously to alternate Magnetic Stripe card by IC card. This paper analyzes EMV standard that is selecting public key cipher, and research wishes to study unexhausted EMV PKI relatively than internet PKI, WAP PKI etc. This paper propose utilizable EMV base Payment PKI model in IC card base payment system development, and developed EMV CA system with this. Also, this paper supplemented IC card Authentication mechanism that is defined in EMV standard, and propose 'Efficient smart card Authentication mechanism' to improve performance of this mechanism, and estimate performance.
