Lockscreen is one of the most frequently encountered interfaces by smartphone users. Although users perform unlocking actions every day, there are no benefits in using lockscreens apart from security and authentication purposes. In this paper, we replace the traditional lockscreen with an application that analyzes facial expressions in order to collect facial expression data and provide real-time feedback to users. To evaluate this concept, we have implemented Quantified Lockscreen application, supporting the following contributions of this paper: 1) an unobtrusive interface for collecting facial expression data and evaluating emotional patterns, 2) an improvement in accuracy of facial expression detection through a personalized machine learning process, and 3) an enhancement of the validity of emotion data through bidirectional, multi-channel and multi-input methodology.

The purpose of this study was to investigate the effects of emotional labor on burnout and career commitment of childcare teachers. For that purpose, a survey was taken with 207 childcare teachers in the region. Collected data were analyzed with SPSS 12.0(ver.). The findings were as follows: first, emotional labor(3.05), burnout(3.22), and career commitment(2.86) recorded higher points than average on a 5-point scale. Second, there were significant correlations among the variables of emotional labor, burnout, and career commitment. Third, emotional labor had positive(+) impacts on emotional exhaustion and depersonalization of the burnout subvariables and no significant impacts on personal accomplishment. Fourth, emotional labor had significant negative(-) effects on career commitment. Those findings show that the emotional labor of childcare teachers has influences on their burnout and career commitment on which it was estimated to have tacit effects. It is thus required to recognize and reevaluate the importance of emotional labor and establish a foundation for a social support system.

SNS is growing by leaps and bounds, and many users of SNS are using by a medium of communication. Using SNS users are using means of their own news and the change of emotional expression. In this study using emotional elements to the program was implemented to classify the message. Extraction of emotional elements were used for emotional vocabulary in OMLS (Ocean-Monmouth Legal Services). Emotional elements were extended by The Roget of the thesaurus and WordNet.

In the era of the 4th industrial revolution, we are living in a flood of information. It is very difficult and complicated to find the information people need in such an environment. Therefore, in the flood of information, a recommendation system is essential. Among these recommendation systems, many studies have been conducted on each recommendation system for movies, music, food, and clothes. To date, most personalized recommendation systems have recommended clothes, books, or movies by checking individual tendencies such as age, genre, region, and gender. Future generations will want to be recommended clothes, books, and movies at once by checking age, genre, region, and gender. In this paper, we propose a recommendation system that recommends personalized clothes and food at once according to the user's emotions and weather. We obtained user data from Twitter of social media and analyzed this data as user's basic emotion according to Paul Eckman's theory. The basic emotions obtained in this way were converted into colors by applying Hayashi's Quantification Method III, and these colors were expressed as recommended clothes colors. Also, the type of clothing is recommended using the weather information of the visualcrossing.com API. In addition, various foods are recommended according to the contents of comfort food according to emotions.

Happiness index is a measurement system for understanding collective happiness. As values change, studies have been proposed to add the value of behavior to the happiness index. However, there is a lack of studies analyze the relationship using individual emotions. Using a deep learning model, we predicted happiness index using social variables and individual emotional index. First, we collected social and emotional variables from January 2005 to December 2020. Second, we preprocessed the data and identified significant variables. Finally, we trained deep learning-based regression model. Our proposed model was evaluated using 5-fold cross validation. The proposed model showed 90.86% accuracy on test sets. Our model will be expected to analyze the significant factors of country-specific happiness index.

현재 가정을 비롯한 여러 분야에서 서비스 로봇(청소 로봇, 애완용 로봇, 멀티미디어 로봇 둥)의 사용이 증가하고 있는 시장상황을 보이고 있다. 개인용 서비스 로봇은 인간 친화적 특성을 가져야 그 선호도가 높아질 수 있는데 이를 위해서 사용자의 감정 인식 및 표현 기술은 필수적인 요소이다. 사람들의 감정 인식을 위해 많은 연구자들은 음성, 사람의 얼굴 표정, 생체신호, 제스쳐를 통해서 사람들의 감정 인식을 하고 있다. 특히, 음성을 인식하고 적용하는 것에 관한 연구가 활발히 진행되고 있다. 본 논문은 감정 인식 시스템을 두 가지 방법으로 제안하였다. 현재 많이 개발 되어지고 있는 음성인식 모듈을 사용하여 단어별 감정을 분류하여 감정 표현 시스템에 적용하는 것과 마이크로폰을 통해 습득된 음성신호로부터 특정들을 검출하여 Bayesian Learning(BL)을 적용시켜 normal, happy, sad, surprise, anger 등 5가지의 감정 상태로 패턴 분류를 한 후 이것을 동적 감정 표현 알고리즘의 입력값으로 하여 dynamic emotion space에 사람의 감정을 표현할 수 있는 ARM 플랫폼 기반의 음성 인식 및 감정 표현 시스템 제안한 것이다.

최근 모바일 기기가 보급됨에 따라 모바일 기기를 활용한 상황 공유 시스템에 대한 관심이 커지고 있다. 상황공유를 다룬 기존 연구들은 대부분 위치를 비롯한 저수준 상황만을 공유하며 고수준 상황인 행동과 감정 공유를 효율적으로 지원하지 않고 있으며 개인정보보호 단계를 수동으로 설정해주어야하는 단점이 있다. 본 논문에서는 모바일 기기의 센서들로부터 수집되는 저수준 상황과 행동, 감정 등의 고수준 상황을 함께 수집하였으며 베이지안 네트워크를 이용하여 설계한 소셜 네트워크를 기반으로 행동, 감정, 그리고 관계를 효과적으로 보여주도록 하였다. 또한 관계정보를 바탕으로 개인정보보호 단계를 자동으로 설정해주어 친밀한 사용자에게만 자신의 상황을 공유할 수 있는 상황 공유 시스템을 설계 구축하였다. 실험에서는 실제로 구성된 모바일 소셜 네트워크에서의 관계를 바탕으로 상황 정보를 공유하는 폰북과 맵브라우저로 구성된 컨텍스트뷰어 어플리케이션을 통해 제안하는 시스템의 유용성을 보였다.

Ribosomal Protein S4Y(RPS4Y) gene is the human sex-linked gene on the Y chromosome. There are a number of reports on the sex determination using RPS4Y gene analysis for prevention and diagnosis in sex-linked disease. Thus RPS4Y gene is a reliable genetic marker for sex determination in forensic medicine. In general, the sex determination of an unidentified body can be achieved based on anatomical characteristics, but sometimes sex determination was considered to be difficult such as pre-adolescent bodies or decomposed, mutilated bodies. In this case, Sex determination using PCR method in human teeth produces good results. Because human teeth have a great structural durability, the DNA well preserved in the teeth. So author isolated nuclear DNA from the 20 human teeth(10 males, 10 females), performed to detect RPS4Y gene by PCR method. Samples were divided four group(10 pulp and 10 dentinal tissue in male, 10 pulp and 10 dentinal tissue in female). It was found that detection of RPS4Y gene for sex determination was possible in all the male pulp tissues and 6 out of 10 male dentinal tissues. But there was not detected in female pulp and dentinal tissues. In the view of this results demonstrates the possibility that detection of RPS4Y gene with other sex chromosome genes from the human teeth is useful to sex determination in forensic medicine.

This study is designed to examine the influence of emotional labor on the happiness in workplace related with the atmosphere at their working place in the clinical nurses. Data were collected by questionaires from 312 clinical nurses who work in the general hospital in the city "J". In results, emotional labor was related significantly negative correlation with happiness in workplace. Individual differences explained 7.7% of the happiness in workplace and emotional labor explained additional 8.9% of the happiness with control of the individual differences of hierachycal regression, so that the explanatory power of this study was 16.6% (F=6.150, p<.001). According to these data it is necessary to change the employers recognition on the emotional labor of the nurses and to develop the programs which assist and manage the emotional labor of the clinical nurses, in terms of the human network in their working place.
