In AI chatbot service via a messenger, a profile image of the chatbot is the first thing that users see to communicate with the chatbot. This profile image not only manages an impression about the profile owner in SNS on followers, but also makes an important impression about chatbot services on users. Thus motivated, this study investigates proper profile images tailored for the types of chatbot services and users. Specifically, I reviewed the preferred images and expressions of chatbots for each purpose of chatbot service. Then, in a case study, I collected and analyzed the representative chatbot profile images for the purpose of fun and counseling. The profile images are categorized as robot, human, animal, and abstract images. Based on these categories, I surveyed the preferred profile image of the chatbot service in either the text type or image type alternatives. For the purpose of fun, in the text version, I found that both men and women preferred a human image to others. However, in the image version, men preferred woman and robot images while women preferred cute animation character and robot images. For counseling services, both men and women preferred woman and animal images most, which is similar to the results of the text version of questionnaires as well. While both genders consistently preferred real photo images, women tend to like abstract images more than men do. I expect that the results of this study would be useful to develop the proper profile images of AI chatbot for each service purpose.

This study is on the strategy for establishing successful corporate brand image, by understanding the need for increasing brand value based on the level of brand recognition. In order to carry this out, the PICS (Product Image Concentration System) is suggested, which includes Brand Image Analysis on a high-level, Product Image Programming based on the result of the image analysis, and Product Image Coherency Assessment and Management, resulting in setting up a guideline for gaining competitive advantage and brand management. Brand Image Analysis is a method that utilizes image association to understand brand disposition by analyzing the association pattern among available visual materials to measure the corporate and brand image inclinations. As the next step, Product Image Programming establishes design philosophy and principles based on the analysis of brand image, and the Visual Programming is a process for visualizing the intended product image direction. Lastly, Product Image Coherency Assessment examines whether to incorporate design philosophy and principles or not to arrive at an agreed evaluation criteria for developing designs coherent with the brand image. The PICS (Product Image Concentration System) is a practical method for increasing a company' competitive advantage and managing brand. The expectation on this system is to provide a guideline for applying brand image in design process more objectively. For further study, diversification of image spectrum based on expressive keywords and comparative analysis on images as well as a product image interpretation program to understand the order of visual materials will be necessary.

Among growth disorders, 'Short Stature' can be improved through rapid diagnosis and treatment, and for that, it is important to detect early'Short Stature'. It is recommended to measure the height steadily for early detection of 'Short Stature' and checking the kid's growth process, but existing height measurement methods have problems such as time and space limitations, cost occurrence, and difficulty in keeping records. So in this paper, we proposed an 'Development of Kid Height Measurement Application based on Image using computer vision' method using smart phones, a medium that is highly accessible to people. In images taken through a smartphone camera, the kid's height is measured using algorithms from OpenCV, a computer vision library, and the measured heights were printed on the screen through 'a comparison graph with the standard height by gender and age' and 'list by date', made possible to check the kid's growth process. It is expected to measure height anytime, anywhere without time and space limitations and costs through this proposed method, and it is expected to help early detection of 'Short Stature' and other disorder through steady height measurement and confirmation of growth process.

As the cultural importance of local environment has been increasing, interests of local residents for city design has also increased. City design can inspire local residents' pride and redefine the city image to both local and outside world. Therefore, this study analyzes the city's(Pohang city) status, environmental characteristics, and local residents' design image preference; and based on the analysis, this study suggests standard design for public facilities that constitute "streets", that can realize the city image identity. For the suggestion, scenery image and public facilities status of the twenty-four areas in the city were analyzed. Also, to decide the design direction of public facilities that can constitute the city's consistent ideology, thoughts, and image, design preference factors for public facilities by local residents were surveyed and analyzed. The design guidelines and a standard design were established for total of thirty-one public facilities based on the analysis. The outcome will enable provision of communication media to express the charming city image and also of material that can be reflected in the integrated city scenery project in the future.

With the beginning of the 21st century, the rapid change of the environment of education makes the universities eager to develop a new image of themselves (i.e. image marketing). Character, one of the image marketing items, plays an important role for improving the image of universities by connecting the inner members more firmly, preserving the tradition of the university and being used as an advertising instrument. Considering these important roles, universities are focusing on designing character in order to express their identity and image efficiently. In this study, I surveyed the characters of universities and examined that these characters are reflecting the image of their universities, working on unity and harmony of the members and establishing the identity of each university properly. At the same time, I analyzed the relation between characters and symbols of universities. I expect that familiar and identified characters can be an essential element in improving the image of universities by giving visual advertising effects and informing the image of universities distinctively.

In this paper, we propose a new image rejection receiver architecture using simultaneously the high-side and low-side injected LO signals. The proposed architecture has a lower noise figure (NF) performance and a higher linearity characteristic than the previous receiver architecture using a single LO signal. Also, the proposed receiver shows a higher IRR performance about 6dB than that of the previous Weaver image rejection architecture even though the same gain and phase errors between I-path and Q-path exist. To verify these characteristics, we derive an IRR formular of the proposed architecture as a function of mismatch parameters. And we demonstrate its formular's usefulness through the system simulation. Therefore, the proposed architecture will be widely used to implement the image rejection receiver due to its higher IRR performance.

This study performs statistical analysis through a questionnaire in order to examine effects of shapes of beards on a formation of male image in male/female workers in their 30s-40s. The findings suggest that sensitive image response factor depending on the shapes of beards functions as an important one in the modifications of attraction, character and image. Although there is a difference between male and female, in the preference for beards' shapes effective in the change of image, no difference is found in sensitive responses of them according to quantities of beards. This study has an implication for quantifying sensitive responses to the formation effect of male image depending on the shapes of them. It provides a guideline for total image making to males who want to change their external image formation according to shape changes of beards in the future, and is simultaneously expected to be used as basic and applied materials in the beauty industry for males.

현재 다양한 분야에서 AI 가 사용되고 있다. 최근에는 소프트웨어공학 관점에서 요구 사항 분석에 Chat GPT 와 같은 LLM 모델을 적용하고 있다. 하지만 1) 대부분의 생성형 AI 는 불투명한 공정을 통해 3D 이미지가 생성하고, 3D 이미지를 생성할 때마다 다른 이미지를 생성한다. 이에 따라 동일한 인물이나 사물을 사용하고 싶은 사용자들은 동일한 객체가 들어간 그림을 일관성 있게 생성할 수 없다. 2) 또한 LLM 과 이미지 생성 AI 와의 결합이 시도 되고 있지만 문장 의미 분석 성능이 부족하다. 이를 해결하기 위해, 자연어 요구사항을 언어학적 기법을 통해 분석하고, 분석 결과를 기반으로 UML 시퀀스 다이어그램 및 3D 객체 생성 메커니즘을 제안한다. 즉 언어학적 분석 기법을 통해, 요구사항의 정확한 의미와 속성을 추출한다. 그런 다음 추출된 정보를 시퀀스 다이어그램과 매핑하여 3D 객체 이미지를 생성한다. 제안하는 방법을 통해 3D 객체 생성의 소프트웨어 개발 공정 사용으로 생산성을 높여 시간과 비용을 단축할 수 있을 것으로 기대한다.
