  • Immobilized lipases were prepared by physical adsorption using lipase AK, AY, AH, PS and R on Amberlite$^{(R)}$XAD$^{(R)}$7 HP resin. With the immobilized lipases (10%), structured lipid was synthesized by enzymatic interesterification of canola oil, palmitic ethyl ester, and stearic ethyl ester in order to study the reaction characteristics. Among the lipase, the highest protein content was obtained from lipase AH (11.41%) before immobilization, while the highest levels of bound protein was observed from immobilized lipase AK (63.91%). Immobilized lipase AK had the highest interesterification activity (38.3% of total saturated fatty acid). Lipase AK was also used for a continuous reaction in which the slow flow of reactant resulted in increased reaction rate. Reusability of immobilized AK, AH and PS increased at the second reaction (120-196.5%). However, the activity of immobilized AK, which had the highest bound protein content (63.91%) decreased after the third reaction, while the activity of immobilized AH and PS was maintained until the sixth reaction.

  • Purpose: Although a Do-Not-Resuscitate (DNR) order is widely in use, it is one of the challenging issues in end-of-life care. This study was conducted to investigate attitudes toward DNR according to education and clinical experience. Methods: Data were collected using a structured questionnaire comprising 30 items in a tertiary hospital in Seoul, Korea. Results: Participants were 238 nurses and 72 physicians. Most participants (99%) agreed to the necessity of DNR for reasons such as dignified death (52%), irreversible medical condition (23%) and patients' autonomy in decision making (19%). Among all, 33% participants had received education about DNR and 87% had DNR experience. According to participants' clinical DNR experience, their attitudes toward DNR significantly differed in terms of the necessity of DNR, timing of the DNR consent and post-DNR treatments including antibiotics. However, when participants were grouped by the level of DNR education, no significant difference was observed except in the timing of the DNR consent. Conclusion: This study suggests that the attitudes toward DNR were more affected by clinical experience of DNR rather than education. Therefore, DNR education programs should involve clinical settings.

  • While many research focused learners as those who excel in mathematics or science, the identification of learners with potential or demonstrated talent in visual art has also been the meaningful research topic. Since these learners exhibit high performance capability in intellectual, creative and artistic areas, they require services or programs not ordinarily provided by the schools. This research tried to clarify what high performance means when speaking of learners with outstanding talent in the visual arts based on the relevant literature. Also, this research introduced the recent trends in the field of art gifted and talented education. In order to demonstrate critical issues and find new directions in art education for gifted learners, this research conducted the survey, and this survey target group was arts high school students. Based on the survey analysis, this research conducted the semi-structured interviews with focal participants including the teachers and an artist. Interviewees generated many meaningful issues, and interview analysis reconceptualized art education for gifted learners as following. 1) Gifted education should consider learners' excellence, equity, troubles, and struggles that often go unnoticed. 2) We should reform the criteria, standards, and strategies in finding art gifted learners. 3) In order to facilitate meaningful and creative art education, higher education institutions need to change the current college entrance exam. 4) The goal of gifted art education is not only raising the world-class artists. 5) Meaningful art education for gifted learners is in interaction with the environment including group dynamics, parents influence, and teachers.

  • The purpose of this study is to develop a model of the TOC (Table of Contents)-based research record system and to comparatively analyze its usability, in order to comprehensively and systematically manage and practically use the various research records generated from the entire process of research and development. For this purpose, the templates for technical recording and the components of each item were proposed to enable technical recording based on TOC, and structured contents were designed to organically connect between these TOC technical records and existing research records. Also, a database logical schema was developed to design a database, and a test collection was constructed on the basis of research records and TOC technical records. Finally, the model of research record system was constructed by designing TOC record search system and user interface including integrated search system. Based on this model, the usability assessment was performed by comparing the existing distributed general systems with the TOC-based research record system. As a result of the comparative analysis of these two systems, the TOC-based research record system showed generally higher utilization of research records than the general systems.

  • This study aimed to investigate data management practices of university researchers in Korea, as well as their experiences and perceptions of data sharing and reuse. For this purpose, it performed semi-structured interviews of 13 researchers who agreed to participate in interviews followed by a survey conducted prior to this study. The interview participants created or collected research data with various types and formats, and only a few conducted data documentation while they recognized its significance. The majority of participants perceived the period that data would be useful as the period that data can be employed for publications. However, most participants wanted to preserve data beyond the period that data would be considered useful and it indicates they have no small need for data storage and preservation. Participants usually shared data with those whom they have known, such as a personal research group or a research team. While some completely agree with the principle that publicly-funded data should be open to the public, others partially agreed or disagreed with it. Most participants were concerned about being scooped, plagiarism, and maintaining the first right to publish and incentives to mitigate the concerns would be necessary.

  • This study aims to survey patients who underwent a heart valve so as to define their self-care Agency and quality of life, as well as the effect of their self-care Agency on their quality of life. One hundred ten outpatients in two university hospitals in the City of D were surveyed using a structured questionnaire. The findings of this study revealed that for the life quality of patients with a surgery of heart valve, out of a total of 4.0 points, self-care Agency was an average 2.71 points, while life quality was an average 2.96 points, showing not so high scores. Also, it was also found that the higher the physical skills of patients with a surgery of heart valve (${\beta}$=.625, p<.001) were, the higher the quality of their life was. In conclusion, self-care Agency was confirmed as a determinant of the life quality of patients with a surgery of heart valve, and it was found that the higher the self-care Agency of patients with a surgery of heart valve, the higher their life quality was. Thus, in order to enhance the self-care Agency of patients with a surgery of heart valve, nursing assessment of their physical, psychological and mental areas, as well as corresponding appropriate nursing interventions need to be developed.

  • To study the risk factors and effect of gastric cancer screening, case-control study was conducted. From June 2007 to December 2011, 580 newly diagnosed gastric cancer (342 advanced gastric cancer, 171 early gastric cancer) patients were enrolled at the department of general surgery in a university hospital. History of gastric examinations and possible risk factors were collected through interviews with structured questionnaire and reviewed medical chart. Comparing advanced cancer and early gastric cancer were analysed by chi-square test and logistic regression. The results showed that aged 70 and over (OR 2.393; 95%CI 1.329-4.310), Ex-smoker (OR 1.612; 95%CI 0.970-2.680), blood type A (OR 1.784; 95%CI 1.035-3.075), and H. pylori infection (OR 1.699; 95%CI 0.905-3.191) were important risk factors for advanced gastric cancer compared to early gastric cancer. Weight loss (OR 2.752; 95%CI 1.333-5.684) and indigestion (OR 1.574; 95%CI 1.069-2.319) were also important sign and symptom. Although the results cannot find effect of screening, national policies on early cancer detection must conduct.

  • The aim of this study was to investigate the effects of death education on the attitude toward DNR, fatigue, and quality of sleep for generic care worker. This study followed a nonequivalent control group and a non-synchronized design. This study was performed in a visiting generic care service institution in J city, Chung-Cheong province, Korea between February 15 to May 30, 2016. The study included 43 participants who agreed to participate in this study. They were randomly divided into two groups: 21 participants in the experimental group and 22 in the control group. Participants in the experimental group received death education 2 hours per day, once a week, for a duration of greater than 8 weeks. The effect of treatment was measured using a structured questionnaire on the attitude toward DNR, fatigue, and quality of sleep before and after 8 weeks of intervention. Data were analyzed using t-, chi-square, Fisher Exact- and paired t-tests. The experimental group showed a significantly increased attitude toward DNR (p=0.001) and quality of sleep (P<0.001), whereas significantly decreased attitude toward fatigue (p=0.030) than the control group after 8 weeks of intervention. The death education program was shown to be an effective nursing intervention for generic care workers. Therefore, we can consider the possibility of incorporating death education in the nursing program.
