Clustering, a technique for the analysis of the genes, organizes the patterns into groups by the similarity of the dataset and has been used for identifying the functions of the genes in the cluster or analyzing the functions of unknown gones. Since the genes usually belong to multiple functional families, fuzzy clustering methods are more appropriate than the conventional hard clustering methods which assign a sample to a group. In this paper, a Bayesian validation method is proposed to evaluate the fuzzy partitions effectively. Bayesian validation method is a probability-based approach, selecting a fuzzy partition with the largest posterior probability given the dataset. At first, the proposed Bayesian validation method is compared to the 4 representative conventional fuzzy cluster validity measures in 4 well-known datasets where foray c-means algorithm is used. Then, we have analyzed the results of Saccharomyces cell cycle expression data evaluated by the proposed method.

This study explores the change of family policy in Germany focused on political ideologies and instruments of CDU/CSU and SPD. In past 50 years after the 2. world war the family policy in Germany has been influenced by ideologies of 2 major political parties. With conservative political perspectives, CDU and CSU intend to strengthen the institution family and traditional division of domestic work. Therefore, they prefer indirect support methods by income tax benefit for family as political instrument. SPD with liberal political perspectives intends to support working married women and children. As political instrument SPD prefers allowance for child to indirect support system. This different political perspectives of 2 major parties have been reflected automatically on the federal administrative system(BMFSFJ) which takes responsibility of family policy in Germany. Through the analysis of attitudes to family policy of major parties in Germany this paper attempts to be manifest the problem of korean family policy and to find implications of german modell.

The purpose of this study is to identify contradictions in library internship, and address them. As a case study, students who were enrolled in the internship class opened in the 2016 fall semester in a university in Seoul were interviewed. Through applying Activity Theory, the process of internship and contradictions presented in its process were analyzed. The findings indicate that students were satisfied with their internship experience. The internship experience also makes positive impacts on students in terms of understanding the library and information science and deciding their future career as a librarian. Such contradictions as internship duration, operation of the internship process, level of participation or practice, and overlap of part-time experience in a library were identified. This study suggests to make the internship systematic in order to address the contradictions through that all parties in internship are actively participated in internship and that they share information related with the internship.

This study aims to look at overall adolescents' perceptions of library and reveal the relevance of search engine sources and library sources compared each elements of them and find out any related issues of perceptions of library and information use of them. The data for this study were collected through survey and analyzed descriptive statistics and correlation analysis using the data. The result shows the population users preferred search engine over library as their information search tool, and they used library as primarily a source of information for printed materials such as books and most of them don't use the library often. Also the result shows the population users tend to select information when it is easy to get and fast to access. Correlation analysis such as ${\chi}^2$ and Spearman were implemented and the result of the correlation shows that many factors of this study covered-such as comparison of information sources- have significant differences each other.

Colors that stimulate human emotions in everyday life are one of the important factors in animation production. The research on color has been actively carried out in relation to the importance and nature mainly for animation production. However, researches that investigated different views for specific color by geographic characteristics are rare. Therefore, information was collected through questionnaire survey and empirical analysis was conducted using SPSS statistical package to analyze preference of Korean and Chinese people for the Chinese traditional colors. The analysis results showed that both Korean and Chinese groups preferred red color among Chinese traditional colors. This preference for red was statistically significant in both groups, indicating that the intensity of preference for red was different even though Korean and Chinese equally preferred red. Furthermore, among 10 red colors, the preferred red was different between Chinese and Korean. Based on these results, it is suggested that the color should be selected considering the characteristics of the intended market for Chinese animation production and the personality of the viewers who watch the animation products.

The non-contact body temperature measurement system is one of the key factors, which is manage febrile diseases in mass facilities using optical and thermal imaging cameras. Conventional systems can only be used for simple body temperature measurement in the face area, because it is used only a deep learning-based face detection algorithm. So, there is a limit to detecting abnormal symptoms of the infants and young children, who have difficulty expressing their opinions. This paper proposes an improved facial expression recognition algorithm for detecting abnormal symptoms in infants and young children. The proposed method uses an object detection model to detect infants and young children in an image, then It acquires the coordinates of the eyes, nose, and mouth, which are key elements of facial expression recognition. Finally, facial expression recognition is performed by applying a selective sharpening filter based on the obtained coordinates. According to the experimental results, the proposed algorithm improved by 2.52%, 1.12%, and 2.29%, respectively, for the three expressions of neutral, happy, and sad in the UTK dataset.

This study aimed to examine the personality traits of a specific group using color reflection reading (CRR) analysis. An experiment was conducted to examine the color preferences of dental hygienists in a certain community. The color psychology test was conducted with 238 dental hygienists currently employed in dental clinics or hospitals in Gwangju, Jeollanam-do, in the form of a self-administered questionnaire. Participating dental hygienists were differentiated into groups by their order of selection of eight different colors, and the results were analyzed using SPSS 22.0. The analysis results showed that the most common first-, second-, and third-choice colors were magenta, yellow, and magenta, respectively. By age, magenta was the most common first-choice color in all age groups. When the results were analyzed by marital status and the presence or absence of offspring, the same results were obtained. Yellow and blue were the most common second-choice colors for married and unmarried participants, respectively. The findings were expected to provide data for human resource management, such as for developing better working environments that account for stress relief or psychological stability using color preferences or complementary colors.

Our students are shocked by the results that there is an inverse proportion between academic achievement and life satisfaction. Recently, the Organization for Economic Cooperation and Development (OECD) published the PISA 2015 Student Well-Being Report. According to the report, Korean students' education is the highest among OECD countries, but their life satisfaction is the 47th ranked among the 48 OECD and non-OECD countries.[1] This is the cause of the unilateral education using collective achievement in evaluation methods. Therefore, I propose a personalized integrated model utilizing block chain technology. I suggest a personalized education and evaluation system model using selective education and personal approval rather than from teachers' unilateral education. This will no longer open the student's achievement grade system to the public. This change will be accomplished utilizing block chain technology. This technology is characterized by security, transparency and dispersion. The result of this work can be used to improve students' quality of living through a management system of personalized education and evaluation, based on the nature of education.

The purpose of this study is to reveal the causal relationship between core categories experienced by firefighters in the organization based on the grounded theory as a method of qualitative research. In this study, we interviewed 50 firefighter information providers who work in Seoul in 2014, 2017, and 2018, and conducted a research model that shows the causal relationship of core categories through open coding, axial coding, and selective coding. As a result, compassion experienced by information providers is revealed as a core category, and this compassion has a positive effect on positive work related identity, collective self esteem, and job performance. Therefore, the theoretical implication of this study is that it has derived a research model that shows the causal relationship between compassion and job performance based on grounded theory as a qualitative research methodology. This study will contribute to the formation of the organizational culture that enables firefighters who desperately need compassion in the fire department organization to more actively exchange compassionate actions.

As fierce competition is expected in the wearable devices marekt, it is needed to develop a technology planning that can increase consumer acceptance. This study aims to provide implications for technology planning of wearable devices by examining consumer preferences for the devices. For this purpose we employed a conjoint analysis. In the process of the analysis, we considered the trend of anticipatory standardization for wearable devices in an attempt to improve objectivity of analysis whilst many previous studies relied on focus group interview. For the anticipatory standardization information, we utilized liaisons and projects of wearable devices at International Electrotechnical Commission, and we designed a conjoint survey on the basis of the information. We conducted an online survey, and a total of 229 individuals responded to our survey. The result of conjoint analysis shows that main use and enhanced features were more important attributes than the others were. However, consumer preferences for detailed levels of each attribute were different by gender and age groups. This result implies that technology planning of wearable devices require distinct approaches by consumer segments.
