As the computer technology grows so fast, it can affect the human life in every fields. Specially, advent of Digital epoch is changing human life completely. In the past, people should get the information through the mass-media. But these days we can produce and provide some information through new media, Internet. In other words, two-ways communication like internet make individual be the producer in the information stream. Especially, net generation is different form the old generation and they want to express themselves distinctively from others. Nevertheless, they can't have the chance to express their identity properly and only they try to satisfy their needs by consuming special goods. In this article, I want to suggest a program that an individual can express their own identity and image. I will transform CIP (Corporate Information Program) and adjust it to an individual case. This is different from the previous study that emphasize the external factor figure, etc. First, we will find the MI(mind identity) and the BI(behavior identity). Second, we will present the VI(visual identity) by using two factors. - MI, VI. Finally, we will analyze them totally and make the PI(personal identity ) that can express their own identity and philosophy well. Through this programs, they can express themselves well and get the chance to think creatively. I am sure this program will have more implications about image strategy.

Recently there are increasing demands for establishing its peculiar city image in Korea. In establishing a urban image, streetscapes of various functional regions in city have very important roles. And many streetscape were designed and are under design for that purpose. There are many factors involved in the image-generation of streetscape, and the facade is one of the most important factors. In this study, we surveyed many factors in the city-regions of various functions to find out desirable characteristics of facade for each region. And we are going to use there findings as a basic data in the future streetscape design. We selected traditional region(Insadong, Chongro-gu, Seoul), apartment-type residential region (Apkujung-dong, Kangnam-gu, Seoul), and newly developed-downtown (Dunsan-dong, Seo-gu, Daejun) as streetscapes of various functions for facade study. Texture, color, form, size, structure and location of the following facade components were surveyed and analyzed. The surveyed components were window, entrance, equipment, signboard, show window.

The necessity for a technique to protect intellectual property of a digital content has been increasing, especially for the image/video contents which are the most favorite because of their high information-intensive property. According to this demand, this paper proposed a digital watermarking algorithm, which is recognized as the most promising technique. This algorithm targets MPEG compression system and the watermarking process is to be performed during the compression process. It inserts watermark only in Y components of I-frames. Experimental results showed that the proposed method satisfied both imperceptibility and robustness against various attacks. The PSNR difference between the compressed images(the average compression ratio was about 27:1 with Y:Cb:Cr=4:2:0 color format for TM5-based compression) with and without watermarking was only 1.8dB ($4.2\%$). In each case that the resulting image after an attack was reusable the normalized correlation between the extracted watermark and the original one was above 0.8.

Humans are provided with a wide range of public benefits from ecosystems and agricultural ecosystems, but the establishment of the horticulture complex could be a space that hampers the public function of the agricultural ecosystem. In this study, we sought to focus the function of landscape creation of agricultural landscape and tried to analyze the landscape of the horticulture complex. Therefore, This study aims to suggest ways to build a greenhouse complex which is being indiscreetly introduced in the agriculture landscape through environmentally-friendly manner and minimize the function of the ecosystem service. We divided the greenhouse complex into two categories of Plastic Greenhouse(v) and Glass Greenhouse(g), and compared them to the Netherland and Japan counterparts. Each image of research areas was selected by 3 pics and polled by a total of 101 people. The results of the Evaluation of Landscape Image are as shown in the figure. Netherland Glass Greenhouse scored 1.80 in terms of 'Neat' which is one of the given 15 adjectives. Study results shows that Korean Plastic Greenhouse landscapes need to endeavor Japanese vinly greenhouses and Dutch glasshouses. Consequently, an analysis on the elements of landscapes including green area, variant elements, separation distance is essential in order to improve our country's greenhouse complex landscapes. In this regard, continuous research is required to improve rural landscapes and harmonize large-scale horticultural facilities into the existing agricultural ecosystem.

With a growing interest in the Han River Skyline, which greatly influences Seoul's image, careful consideration of the skyline form has become crucial in the redevelopment plans for apartment complexes along the Han River. The Seoul Metropolitan City government has lifted the height limitations for apartments along the Hang River to cultivate a vibrant skyline. However, traditional skyline analysis often overlooks specific attributes, limiting the provision of precise guidelines for Seoul's unique skyline plans. Despite advancements in Digital Twin technology, only some tools effectively manage urban skylines with preferred shapes. Hence, this study aims to make a substantial contribution to the advancement of a Digital Twin 3D modeling program capable of effectively managing urban skylines. This is achieved through the utilisation of Conjoint Analysis, which assesses the importance of each attribute in determining the preferred skyline shape. Focusing on Apgujeong apartment complexes along the Han River currently undergoing redevelopment or planned for redevelopment, the study analyses the preferred skyline shape to propose standards for the Digital Twin 3D modeling program development. It also suggests that Conjoint Analysis can be beneficial in this process.

본 논문에서는 실시간 수묵화 기법 렌더링을 제시한다. 기존의 대표적인 렌더링 기법인 Phong-Shading 기법은 사진과 같은 사실적인 표현이 가능하다. 하지만 인조적이고 기계적인 느낌이 강해 미술가가 그린 그림과 같이 다양한 느낌을 표현하는데 한계가 있다. 이를 해결하기 위해 우리는 기존의 미술가들이 써왔던 다양한 기법 중 동양화의 특징들을 3차원 실시간 렌더링 기법에 적용하고자 한다. 본 논문에서는 실시간 렌더링을 위해 정교함에 치중하기 보다는 수묵화의 주된 특징들을 빠르게 표현할 수 있는 새로운 알고리즘을 제시한다. 동양화 작품들의 특징을 살펴보면 전체적으로는 일관성을 유지하지만 세부적으로 보면 모두 불규칙한 패턴을 이루고 있다는 것이다. 이러한 특징들은 붓 끝에서 오는 불규칙성 때문에 오는데 본 논문에서는 이러한 정을 쉐이딩과 외곽선 그리고 색 부분으로 나누어 적용하였다. 사용자는 다른 복잡한 과정 없이 단지 불규칙 정도만을 조절하여 다양한 이미지를 창출해 낼 수 있다.

Modern fashion shop is changed by the changing of fashion style. And as purchasing pattern is changed to consuming pattern which has strong individuality, functions as space which reflet characteristics of products and consumers in order to present sensitive and individual image are also required, besides conventional concept as space which simply focused on sale. Meanwhile, in the 1980's, the fashion presented retro mood modernly by popularization of post-modernism and introduced minimalism that is one of the anti-cultures in the 1960's. Recently minimalistic trends which are expressed by various attempts and a new point of view are introduced to the fashion shop by interior designer. Therefore, in this study, minimalistic characteristics which appear in the composition of interior space of the modern fashion shop are researched by theoretical consideration and analysis of examples and consistent direction of fashion shop is presented.

Though authentication using biometric techniques has conveniences for people, security problems like the leakage of personal bio-information would be serious. Even if cancelable biometric is a good solution for the problems, only a few biometric authentication scheme with cancelable feature has been published. In this paper, we suggest a face authentication scheme with two security factors: password and face image. Using matching algorithm in the permuted domain, our scheme is designed to be cancelable in the sense that templates that is composed of permutation and weight vector can be changed freely.

The use of drones is gradually increasing for the efficient maintenance of large-scale renewable energy power generation complexes. For a long time, photovoltaic panels have been photographed with drones to manage panel loss and contamination. Various approaches using artificial intelligence are being tried for efficient maintenance of large-scale photovoltaic complexes. Recently, semantic segmentation-based application techniques have been developed to solve the image classification problem. In this paper, we propose a classification model using semantic segmentation to determine the presence or absence of failures such as arcs, disconnections, and cracks in solar panel images obtained using a drone equipped with a thermal imaging camera. In addition, an efficient classification model was implemented by tuning several factors such as data size and type and loss function customization in U-Net, which shows robust classification performance even with a small dataset.

Today, the police alone can not prevent a crime. And the police is limited to meet for people's the increased needs on public safety. So the police and the community needs the cooperation of a variety of resources. Police in cooperation with community resources to respond to the crime's most professional and the private sector is a private security. However, the role of private security for cooperation policing is insufficient in South Korea. So for this study to build a cooperative policing in South Korea as private security for the following four kinds of directions are presented. First, as a private security of the United States and Japan, specializes in diversified business sectors. Simple human-oriented private security of the building security get out. Instead, take the high-tech crime prevention or industry complex security should be changed to a professional organization. Second, the interaction between police and private security should be increased. Police and private security through regular meetings between the need for mutual interests and build consensus is needed. The role of private security companies to be represented on the Security Association of South Korea's active role in the matter. Third, efforts to improve the image of private security activities and the publiciy activity of private security is needed. Some of the private security in an effort to escape a negative image to the people and actively promote a positive image is necessary. Finally, for South Korea to the level the cooperation between the police and private security are required to develop system models. Front-line policing priority in the field and the mutual understanding between the police and private security in an effort to have a positive perception is needed. Equal partners, especially the police and private security to private security companies to have recognized experts in their own recruitment and training should be improved by strengthening the expertise.
