최근 SNS 의 발달로 인해 자신의 감정을 빠르고 효과적으로 전달할 수 있는 이모지의 중요성이 커지고 있다. 하지만 이모지를 수동으로 생성하기 위해서 시간과 비용이 많이 들고 자신의 감정에 맞는 이모지를 찾아야 하며 해당 이모지가 없을 수 있다. 기존 DCGAN 을 활용한 이모지 자동 생성연구에서는 부족한 데이터셋으로 인해 G(Generator)와 D(Discriminator)가 동등하게 학습하지 못해서 두 모델 간 성능 차이가 발생한다. D 가 G 보다 최적해에 빠르게 수렴하여 G 가 학습이 되지 않아 낮은 품질의 이모지를 생성하는 불안정 문제가 발생한다. 이 문제를 해결하기 위해 본 논문에서는 Latent vector 분포를 데이터셋에 맞게 조정하여 적은 데이터로 G 에서 안정적으로 학습할 수 있게 하는 G 구조와 다양한 이모지 생성을 위한 Latent vector 평균 조정 기법을 제안한다. 비교 실험 결과 불안정 문제를 개선하였고 FID 와 IS 수치를 통해 성능 개선 효과를 검증했다.

In this study, a design of emoticons based on sex was studied through Kansai engineering method. First, we developed emoticon prototypes according to a design guideline derived from existing related literatures. Then, the design guidelines was updated from the survey results on the properties of emoticon, and the two sets of modified emoticons were developed from them. Another survey was executed to evaluate the degree of emotional expressions on the three types of emoticons developed in this way. A small number of emoticons were found to be designed fulling the researcher's intention. However, in many other emoticons, it was difficult to find a consistent characteristics. Even though it was observed through detailed analysis that one of the main causes of this result was lack of detail in the design guidelines, the results of this study are expected to be used as basic data for the development and application of character - type emoticons suitable for male and female users' emotional expressions in future researches.

They use emoticons as assistance to express their emotion on CMC communications. Emoticons have been developed into diverse forms like text emoticon, image emoticon, animation emoticon. However emoticons represent the emotion only in simple way, not in specific because the shortage of grouping expressions of the emotion. So, the emoticons used nowadays should be grouped specifically in order to help produce the modulated animation emoticons those are able to represent the feeling in specific and diverse way and be used conveniently. Therefore, this thesis is going to propose the design method of a new kind of animation emoticons those can make what animation emoticons used nowadays are not able to through the grouping and analyzing expression images according to faces, gesture(hand), and backgrounds(decoration) focused on the animation emoticons in messenger programs.

이모티콘은 자신의 감정과 개성을 표현하는 중요한 수단이 되었다. 그러나 이모티콘의 수가 너무 많아 이에 따른 적절한 이모티콘을 선택하기가 어려워 졌다. 따라서 본 제안에서는 사용자에 선호도에 따라 이모티콘을 제안하여 보다 손쉬운 인터페이스를 제공하고자 한다.

Although it is well known that the chincup, used to correct a skeletal class III malocclusion in growing children, reduce the mandibular prognathism by arresting the growth of the mandibular length and rotating the mandible posteroinferiorly, the majority of the studies about chincup is focused on condylar head that plays an Important role in mandibular growth. The aim of this study was to evaluate the morphologic change of the mandibular symphysis where extraoral force is applied directly during chincup treatment. The data lot this study were obtained from lateral cephalometric radiographs of 62 growing children(chincup group:32, control group:30) with mixed dentition who had been accepted lot the orthodontic treatment at Chonbuk National University Dental Hospital. The results were as follows : 1. Symphysis height was increased both in chincup therapy group and control group during treatment. Symphysis depth was decreased or maintained the initial values in chin cup therapy group, whereas increased in control group. Posterior symphysis depth was decreased both in chin cup therapy group and control group, but anterior svmphysis detph was increased in control group, whereas decreased in chincup therapy group. 2. Chin depth and chin curvature were increased in control group, whereas maintained or decreased in chincup therapy group during treatment. Chin angle, menton ang1e and symphysis angle were decreased in control group, whereas increased in chincup therapy group. It suggested that bone deposition in pogonion area that occur normally with mandibular growth was supressed by direct contact of chincup. 3. When growing children wear chincup, symphysis morphology was maintained due to inhibition of forward growth at mandibular symphysis. It may be due to the suppression of bone deposition in anterior part of symphysis.

Cell phone users frequently send and receive text messages with emoticons in their everyday lives, but emoticon and its emotional effect on message in mobile context has not been focused on. The purpose of this study is to investigate the emotional effect of emoticons on interpretation of text message considering valent texts and emoticons. Study 1 showed the effect of valent emoticons on neutral message, and also revealed that existence of emoticon, regardless of its valence, decreases rigidness and increases familiarity of message. In Study 2 that used positive and negative text messages, we found that emoticon still affects assessing sender's mood state and emotion. Result of interaction between valences of text and emoticon showed that participants in condition of incongruent pairs felt more sarcasm.

The current study investigated the effect of emoji use and gender on job interview training within virtual environment (VE). A 2 (emoji use: use vs. no use) × 2 (interviewee gender) × 2 (interviewer gender) mixed design experiment (N = 80) was conducted. The result shows that emoji may be implemented within VE to promote positive affect. Intimacy predicted better mutual understanding and higher attention. Practical implication is provided as using emoji in virtual environment can be utilized as a practice tool for job interviews, or for other potentially stressful social contexts.

Si-immobilized Sargassum horneri was used to study the adsorption characteristics along with maximum adsorption conditions of heavy metal ions, Cd(II) and Ph(II) on the Si-immobilized Sargassum horneri. More amount of Cd(II) and Pb(II) ions on the Si-immobilized Sargassum horneri than Sargassum horneri were adsorbed. And Pb(II) ions were more adsorbed in all algae than Cd(II) ions more effectively in alkaline than in acidity. Recovery ratios of Cd(II) and Pb(II) ions on the Sargassum horneri were 58.0-62.6%, 61.2-64.4% respectively, Si-immobilized Sargassum horneri 56.8-92.7%, 37.8-47.9%. Recovery ratio of Cd(II) ion was higher on the Si-immobilized Sargassum horneri but it of Pb(II) ion was lower on the Si-immobilized Sargassum horneri.

Today, as a means of online communication, the use of emoticons is activated in SNS. Emoticon is an important element to share impact effects and fun together with various content design attempts. In this paper, we analyze the expression patterns changed through development process of emoticons, and analyze characteristics and effects of emoticons which are combined with traditional culture among the types of emoticons currently used.

Smartphone has become a part of many people's daily lives. The mobile messenger function on the smartphone in particular is the most frequently used services. The mobile communication tool in the age of digital media can be classified into two big categories: text messages and emoticons, the non-verbal expression tool of one's emotions. This thesis has studied the mobile communications made by the non-verbal tool of emoticons. The history of emoticons traces back to the text-based emoticon created by Scott Fahlman, from which graphical emoticons were developed and the sound and animation effects have been added. Many people use emoticons and diverse companies are developing the tool. In this study, the representative emoticon development case of Line Co., Ltd. is analyzed to see the concept, types, development process, collaborations and merchandising of the emoticons. Based on the case of Line, the development orientation and direction of domestic emoticons will be discussed to be culture contents.
