The historical exchanges between the Republic of Korea and Japan have broadly occurred, in terms of both political and cultural aspects, from ancient to modern times. Regarding ancient gardening culture, in particular, Asuka developed gardens with the gardening techniques passed down by the Baekje people. The development of the basic form of a garden pond along with its characteristics, established through such exchanges, is suggested by investigating its components through analysis of data from the gardens of Baekje and Asuka. In terms of the garden pond structure, homogeneity was confirmed between Baekje and Asuka, with a linear rectangular form as the basic design. In addition, the vertical construction technique was used by both ancient kingdoms. In terms of the types of stone used in building the shore of the garden pond, Baekje used diverse types such as natural stone, crushed stone, and cut stone. In contrast, rounded river stone was used by Asuka. Regarding the floor of the garden pond, Baekje used soil, which enabled the planting of lotus flowers. In contrast, Asuka used stones to pave pond floors, which made the growth of plants impossible. In terms of layout, Baekje used ornamental stones for pond landscaping, while Asuka used manmade island and water intake facilities in their pond construction. The effects of Baekje's garden culture on Asuka's garden building can be seen from its influence on the form of the garden pond and shore construction style. In terms of the construction of the garden pond's shore with the same stones and the stone flooring, the garden ponds of the Asuka Kingdom reveal technically unified and refined aspects.

As a result of the popularization of smart devices, smart phones or the tablets have become necessities in modern society. In this current of the times, the bring-your-own-device environment, in which personally owned smart devices are utilized in life, is attracting attention. In this context, this paper designed a Wi-Fi remote ordering system focused on the BYOD environment. If the Wi-Fi remote ordering system based on the BYOD environment is popularized, positive effects can be expected such as the enhancement of efficiency and the increase of customer benefits. As a typical example, real-time customer requests via smart devices enable the provision of fast services. This paper designed a mobile app for customers' remote ordering and web pages on which member stores can inquire details of orders, manage a menu, and register statistical data on sales. If the Wi-Fi remote ordering system designed by this paper is widely distributed internationally, it is expected that the system will be used usefully by many people.

In the Past, Trend of car security was Physical Something like doorlock system, and The Generation did not have skills connecting External devices. Through Car Development is up, that trend of car security Changed Physical Security to Intelligence Security. This Changes give a chance to hackers to attack this system. This System use CAN(Controller Area Network) Protocol which have three vulnerabilities. First, ID Spoofing, Twice, D - Dos Attack, Third, Android Application Injected Modern cars have many ECU(Electronic Control Unit) to control devices like Engine ON/OFF, Door Lock Handling, and Controlling Handle. Because CAN Protocol spread signal using broadcast, Hackers can get the signal very easily, and Those often use Mobile devices like Android or IOS to attack this system. if bluetooth signal is spread wide, hackers get the signal, and analysis the bluetooth data, so then They makes certain data to attack ECU, they send the data to ECU, and control ECU installed car. so I suggest that I will prevent this attack to make Auth system and prevent this attack in end of Android.

Most of the wedding shops in the domestic market are more focusing on simply copying the designs of foreign wedding dress designers than making their own designs. Beyond the purpose of how to improve the wedding dress designs which is what other previous studies were aiming, this study goes deeper than that, concentrating on separate designing of dress for a wedding celebration and a rehearsal with photo shoots. Add to this, the study also differentiates itself from others in the past, investigating how to make a gown that hides a bride's physical shortcomings. For this study, the researcher studied the literature in terms of theoretical review, and conducted the empirical research through the photo analysis of 2,725 wedding dresses which brides really wore according to domestic brides' body shapes, their images, and situations. The researcher designed 8 wedding dresses for wedding ceremony and rehearsal shooting for brides with thick arms or wide shoulder under the concept of 'Romantic Story in Your Heart'. The wedding dress's image types for photo analysis were limited to the romantic type, the elegance type, the modern type, and the classic type. The researcher applied the empire-silhouette, the one-shoulder neckline, the raglan sleeves, the cap sleeves, and the shoulder accessories to the wedding dress designs judged as effectively making up defects in body shape and making nice images as well as other design factors seen from the analysis result.

Active phased array antenna structure is used for modern multi-function radars. To search targets in high clutter environment, the radar receiver needs high dynamic range performance. Though active phased array antenna structure lead to increase of SNR, the SFDR is not increased. In this paper, high SFDR receiver of X-band active phased array radar was designed and manufactured. One channel digital receiver is connected to 32 T/R modules and one PCB assembly is composed to 2 channel digital receivers with RF part, ADC part, LO distribution part and digital down conversion part. A commercial FIFO board was used for digital receiver measurement about major performance in digital output signal condition. The measured digital receiver gain and SFDR is 33 dB and more than 81 dBc each.

As modern society needs to process of acquisition, storage and transmission of much information, the importance of signal processing is increasing and various digital filters are used in the two-dimensional signal such as image. And kinds of these digital filters are IIR(infinite impulse response) filter and FIR(finite impulse response) filter. And FIR filter which has the phase linearity, the easiness of creation and stability is applied to many fields. In design of this FIR filter, flatness property is a important factor in pass-band and stop-band. In this paper, we designed a 2-D Circular FIR filter using the Bernstein polynomial, it is presented flatness property in pass-band and stop-band. And we simulated the designed filter with noisy test image and compared the results with existing methods.

Mirror is a physical reflective surface, typically of glass coated with a metal amalgam, and it is to reflect an image clearly. They are available everywhere anytime and become an essential tool for us to observe our faces and appearances. With the advent of modern software technology, we are motivated to enhance the reflection capability of mirrors with the convenience and intelligence of realtime processing, microservices, and machine learning. In this paper, we present a development of Digital Mirror System that provides the realtime reflection functionality as mirror while providing additional convenience and intelligence including personal information retrieval, public information retrieval, appearance age detection, and emotion detection. Moreover, it provides a multi-model user interface of touch-based, voice-based, and gesture-based. We present our design and discuss how it can be implemented with current technology to deliver the realtime mirror reflection while providing useful information and machine learning intelligence.

In modern society, people will obtain the necessary goods and find meaning of himself and his community through jobs. The meaning of job for people with disabilities is identical with people's with non-disabilities and people with disabilities will live as a member of society through jobs. Because people with hearing impairment have a problem about job such as the short longevity and high turnover, vocational aptitude test which evaluates psychological characteristics, aptitudes and interests is necessary for them. In this paper, we design and evaluate the picture vocational interest inventory supporting the Internet as a vocational aptitude test for people with hearing impairment. We use the picture vocational interest inventory of Korean Employment Development Institute as a implementation target. The previous tests for people with hearing impairment have a problem which an examinee, an examiner and a sign language interpreter are involved in the test at the same space and time. Therefore, our picture vocational interest inventory has no limitation of time and space because it processes on the Internet.

Precise branch prediction is a critical factor in the IPC Improvement of modern microprocessor architectures. In addition to the branch prediction accuracy, branch prediction delay have a profound impact on overall system performance as well. However, it tends to be overlooked when the architects design the branch predictor. To tolerate branch prediction delay, this paper proposes Early Start Prediction (ESP) technique. The proposed solution dynamically identifies the start instruction of basic block, called as Basic Block Start Address (BB_SA), and the solution uses BB_SA when predicting the branch direction, instead of branch instruction address itself. The performance of the proposed scheme can be further improved by combining short interval hiding technique between BB_SA and branch instruction. The simulation result shows that the proposed solution hides prediction latency, with providing same level of prediction accuracy compared to the conventional predictors. Furthermore, the combination with short interval hiding technique provides a substantial IPC improvement of up to 10.1%, and the IPC is actually same with ideal branch predictor, regardless of branch predictor configurations, such as clock frequency, delay model, and PHT size.

The purpose of this study is for considering about Zen fashion in the point of view of culture transition. Through this research, the Far-East including Korea will be confirmed as a center of fashion culture in 21st century. The contents are the meaning of culture transition in Post Modern period, the meaning of Zen and changing of fashion trend as the background of Zen Fashion, and the characteristics of Zen fashion design. The results are as follows: Anti-western movement or dismantlement of culture has been represented the limitation of western centered culture. So the interesting about East means the changing to east from west in ideas. To make new creation in fashion field, the comprehension about the western fashion which has been preceeded and new trials using the our tradition will be needed. Zen is a kind of Buddhism and the essence of it is to find myself and express individual experiences. The change of one's sens of value, new age movement and concerning of environment and ecology make more comfortable, simple and healthy elements in clothing. The fusion style is under a vogue in life style and Zen is the core of this trend. The characteristics of Zen fashion are flat dismantlement which has been know as a Japanese style, oriental minimalism and nature beauty of ecology. This characteristics are found not only the shape, color but the will of the behind. The pursing temperance and naturalism are represented the fashion culture transition from the West to Far-East. Therefore multi points of fashion research is very important and the identify about Korean fashion is required in lately for new fashion paradigm.
