What is the life of an assistant professor working at a college of education look like? The purpose of this paper is to describe and understand the life of an assistant professor as a science education researcher and as a teacher educator from exploring his life in a local national university. The researcher (I) conducted an autobiographic research in which I reconstructed and reflected my life by myself. I collected data/records on the life of myself, and developed a framework to classify them. The life of an assistant professor was categorized into the official life at the university and the personal life, and the former was sorted into education, research, and service and the latter was divided into personal and family. From the various profiles of my life, I found the main theme of 'change' and 'learning,' from which I reconstructed my life in narratives. I can express myself as an assistant professor with 'from myself to others,' 'balancing society and isolation,' and 'increasing room to maneuver through continuous learning.' I reflected my life and the role of a professor at a college of education, and discussed the educational implication of the result.

Social networking services (in short, SNS) allow users to share their own data with family, friends, and communities. Since there are many kinds of information that has been uploaded and shared through the SNS, the amount of information on the SNS keeps increasing exponentially. Particularly, Facebook has adopted some interesting features related to entertainment (e.g., movie, music and TV show). However, they do not consider contextual information of users for recommendation (e.g., time, location, and social contexts). Therefore, in this paper, we propose a novel approach for movie recommendation based on the integration of a variety contextual information (i.e., when the users watched the movies, where the users watched the movies, and who watched the movie with them). Thus, we developed a Facebook application (called MyMovieHistory) for recording the movie history of users and recommending relevant movies.

The purpose of this study is to empirically examine the mediating effects of the acceptance of my extramarital relations, as well as the effects of the individual's openness and emotional isolation on the tolerance of spouse's extramarital affairs. This study is an empirical research based on data analysis obtained by surveying 655 adult men and women. The notable findings are as follow: First, while the openness and emotional isolation does not have direct effect on the tolerance of spouse's extramarital relationship, the direct effect of that on the acceptance of my extramarital relationship is significant. Second, the more acceptance of my extramarital relationship, the less tolerance of spouse's extramarital relationship strongly. Thirdly, the full mediation effect of the acceptance of my extramarital relationship between the individual openness and the tolerance of spouse's extramarital relationship is proved. Moreover, the full mediation effect of the acceptance of mine between the emotional isolation and the tolerance of spouse's is also significant. That is, the effect of individual openness and emotional isolation on the tolerance of spouse's extramarital relationship is influenced by the acceptance of my extramarital relationship. The perception of my extramarital relationship affect the perception of spouse's extramarital relationship. Some practical and political implications regarding extramarital relationship are discussed based on the study's findings.

Purpose: To provide an in-depth analysis of the physical changes in and marital experiences of immigrant women in Korea, considering the differences in their cultural backgrounds. Methods: A qualitative research methodology with a phenomenology perspective was used. Data were collected through interviews from four focus groups and through in-depth interviews from five individuals. Data analysis was carried out using Colaizzi's phenomenological analysis method. Results: Twenty-four participants from nine different nations were interviewed. Three phenomenological theme clusters were identified and six sub-themes were derived. These comprise: "emergence of physical changes", "experienced symptom with negative result", and "coping with my body". The derived themes comprise: "struggling for my body to survive", "changed body after pregnancy and delivery", "diagnosed as normal but", "neglected my health", "using familiar care", and "unfamiliar health service system". Conclusion: Immigrant women by marriage in Korea are new subjects of nursing care. Their physical changes and experiences in coping with marriage at an early stage of immigration as described by themselves provide valuable information for nursing professionals. Cultural differences, problems specific to women, and our social conditions regarding minorities and our patriarchal tradition that discriminates against women affect their health problems. We strongly recommend that nurses should actively determine and engage in the health problems of immigrant women.

The purpose of this study was to explain the process of meaning construction on children's happiness by mothers with young children. The study participants were 16 mothers with young children. The data were collected through the interviews which were conducted during 10 months from March, 2013 to December, 2013. The Data were analyzed according to a grounded theory methodology. The process of meaning construction on children's happiness by mothers included 4 stages, which are as follows. 'Following inseparated social desire and demands', 'Looking around my desire and children's happiness', 'Rearranging interlacing desire' and 'Going to find my children's happiness and my happiness'. And the stages were interacting mothers'time perspectives and diverse ecosystems. Based on the results, the study discussed the characters of interaction on time perspectives and parenting, and discussed influences of meaning construction on happiness.

Objective: The aim of our study was to determine the associations of heifer reproductive performance with survival up to the first calving, first-lactation milk yield, and the probability of being culled within 50 days after first calving. Methods: Data from 33 large Holstein-Friesian commercial dairy herds were gathered from the official milk recording database in Hungary. The data of heifers first inseminated between January 1, 2011 and December 31, 2014 were analyzed retrospectively, using Cox proportional hazards models, competing risks models, multivariate linear and logistic mixed-effects models. Results: Heifers (n = 35,128) with younger age at conception were more likely to remain in the herd until calving, and each additional month in age at conception increased culling risk by 5.1%. Season of birth was related to first-lactation milk yield (MY1; n = 19,931), with cows born in autumn having the highest milk production (p<0.001). The highest MY1 was achieved by heifers that first calved between 22.00 and 25.99 months of age. Heifers that calved in autumn had the highest MY1, whereas calving in summer was related to the lowest milk production (p<0.001). The risk of culling within 50 days in milk in first lactation (n = 21,225) increased along with first calving age, e.g. heifers that first calved after 30 months of age were 5.52-times more likely to be culled compared to heifers that calved before 22 months of age (p<0.001). Calving difficulty was related to higher culling risk in early lactation (p<0.001). Heifers that required caesarean section were 24.01-times more likely to leave the herd within 50 days after first calving compared to heifers that needed no assistance (p<0.001). Conclusion: Reproductive performance of replacement heifers is closely linked to longevity and milk production in dairy herds.

With the decrease of sequencing price, many national projects that analyzes 0.1 to 1 million people are now in progress. However, large portion of budget of these large projects is dedicated for construction of the cluster system or purchase servers, due to the lack of programs or systems that can handle large amounts of data simultaneously. In this study, we developed NGSOne, a client program that is easy-to-use for even biologists, and performs SNP analysis using hundreds or more of Whole Genome and Whole Exome analysis without construction of their own server or cluster environment. DRAGEN, BWA / GATK, and Isaac / Strelka2, which are representative SNP analysis tools, were selected and DRAGEN showed the best performance in terms of execution time and number of errors. Also, NGSOne can be extended for various analysis tools as well as SNP analysis tools.

Many attempts have been made to track the web usage patterns and provide suggestions that might help web operators get the information they need. These tracking mechanisms rely on mining web log files for usage patterns. The purpose of this study is to verify a web agent prototype that was built for mining web log files. The web agent for this paper was made by Java and ASP and the agent came into being as part of a cookie for a short-term data storage. For long-term data storage, the agent used a My-SQL as a Data Base. This agent system could inform that if the data comes from the web data mining agent, it could be a rapid information providing method rather than the case of data coming into a data mining tool. Therefore, the developed tool in this study will be helpful as a new kind of decision making system and expert system.

In this paper, I describe the importance of matrix spraying conditions in imaging mass spectrometry (IMS) to obtain successful imaging results. My developed matrix application methodology, which is a "two-step matrix application" sequentially combined with matrix sublimation and spraying matrix solution can provide high reproducibility and high ion yield compared with a conventional direct spraying method. However, insufficient IMS results were obtained occasionally despite the two-step method. Therefore, I wanted to characterize the methodology to continuously provide high quality data. According to my results, the sublimation time was not a strict parameter, and the most important step was the first spraying condition. This means that the extraction conditions from the tissue section and co-crystallization of the matrix were the most important factors.

Purpose: The purpose of this study was to explore and develop a deeper understanding of the experiences of mothers of premature children receiving rehabilitation therapy. Methods: The participants were 12 mothers with premature children who had received rehabilitation therapy for over 1 year. Individual in-depth interviews were conducted from July to August 2017. The data were analyzed through the phenomenological research method. Results: The participants' experience was structured into five thematic clusters: 'Regret and guilt that premature birth led to rehabilitation therapy', 'Burden of life in an endless tunnel', 'Changes in personal relationships surrounding me and my child', 'Meaning of new life through my child', and 'Desire to expand the rehabilitation of premature infants'. Conclusion: The results of this study will be helpful for developing family-centered care programs for premature infants at high risk of developmental disorders.
