Purpose: This study aimed to understand the experiences of women under 40 years of age with gynecologic cancer. Methods: Semi-structured individual in-depth interviews were conducted with 14 Korean female patients aged 21~39 years with gynecologic cancer. The data were analyzed using Corbin and Strauss' grounded theory approach, including open coding, context analysis, and integrating categories. Results: Grounded theory analysis revealed nine categories and a core category of 'the journey to find my life after losing the life as a typical woman.' The categories that emerged as the conditions are 'Unwelcomed guest, cancer,' 'Completely devastated life as an ordinary woman,' 'Uncertain future,' 'Losing my physical characteristics as a woman,' and 'Life tied with treatments.' The actions/interactions were 'Decrease of interpersonal relationships,' 'A lonely battle to overcome alone,' and 'The power to overcome hardships.' The consequence was 'Live my own life.' Conclusion: This study contributes to the development of a substantive theory of the experience of gynecologic cancer in young women, which has been on the rise in recent years. The study's results are expected to be used as a basis for providing nursing care to help young women with gynecologic cancer adapt to their disease.

The Internet of Things (IoT) significantly increases the amount of data. Database compression is important for big data because it can reduce costs for storage systems and save I/O bandwidth. However, it could show low performance for write-intensive workloads such as OLTP due to the updates of compressed pages. In this paper, we present practical guidelines for the performance improvement of database compression. Especially, we propose the SELECTIVE strategy, which compresses only tables whose space savings are close to the expected space savings calculated by the compressed page size. Experimental results using the TPC-C benchmark and MySQL show that the strategy can achieve 1.1 times better performance than the uncompressed counterpart with 17.3% space savings.

The astronomical data obtained by observations of celestial objects movements are useful in our daily life. These data - such as 1) sunrise and sunset data, 2) data transformation between lunar calendar and solar calendar, 3) solar eclipse and lunar eclipse data, and 4) sun's altitude and azimuth data - were used to important things in the agricultural society and ancient kingdom. In the modern society, these data have been used continuously for the legal disputes, construction of buildings and the other areas. This is a good example of pure science data using directly in our life. However there are difficulties to public service because all the data were printed as an Almanac. Using MySQL, we constructed web-based service system which makes to use them easily. This database system was made for the quick search using the calculated orbital data of celestial bodies.

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.
