Although a commercialization of developed technology is an important factor for firm's competitiveness, the success rate in technology commercialization is significantly low. This fact raises a need of an analysis on factors affecting success in technology commercialization. Thus, in this study, in order to determine the success factors of technology commercialization, statistical analysis is done on 4 different elements of Korean automobile industry firms: managerial group attitude, market orientation, technology quality, and government support; and developed a causal-relationship model of the above elements and commercialization. In the developed model, two moderating variables, corporate ability and industry classification, are added to determine the level of correlations respect to two moderating variables. As a result of hypothesis tests, market orientation, managerial attitude as an antecedent variable; and government support, technology quality as an antecedent variable, both have significant correlation with technology commercialization. For moderating variables, a corporate ability has moderating effects on the connections of managerial attitude, market orientation and technology commercialization; but an industry classification has a moderating effect only on the link between technology quality and government support. The results of this research serve a contribution to the development of R&D efficiency improvement by providing government with direction in science & technology policy.

Purpose: To provide practical data for bioethics education, we identified correlations between recognition of good death, attitude towards withdrawal of meaningless life-sustaining treatment, and attitude towards euthanasia in nurses. Methods: Using convenience sampling, we recruited 218 nurses who had at least six-month work experience in one of the six general hospitals with 500 or more beds in Seoul, Busan, and Gyeongsang province. All participants understood the purpose of the study and agreed to take part in the study. The research tools used included the Concept of Good Death Measure (CoGD), the measurement tool for attitudes towards withdrawal of meaningless life-sustaining treatment (WoMLST), and the measurement tool for attitudes towards euthanasia. Data were analyzed using an Independent t-test, one-way ANOVA, and Pearson's correlation coefficient using SPSS 21 for Windows. Results: Nurses had normal levels on CoGD, WoMLST, and attitudes towards euthanasia. Nurses' CoGD, WoMLST, and euthanasia scores significantly differed depending on their education level, working period, and the importance of religion to them. A negative correlation was found between the CoGD and WoMLST scores, and WoMLST and euthanasia scores were positively correlated. Conclusion: Nurses should be trained to deal with ethical issues that may arise while caring for terminal patients. It is necessary for nurses to understand the concepts related to CoGD, WoMLST, and euthanasia, and to promote bioethics education with focus on decision-making and problem-solving ability in ethically conflicting situations.

This study was performed to identify the importance and performance of hospice volunteer's activities perceived by hospice volunteers. Methods: The subjects were 259 hospice volunteers from six hospitals in Daegu and Gyeongsangbukdo areas. A list of hospice volunteer's activities was developed by authors, based on literature, and interviews with the hospice volunteers were used to measure the perception on the importance and performance of their activities. Data were analyzed by using Descriptive statistics, t-test, One-way ANOVA with Scheffe test, and Pearson's product-moment correlation in SPSS Win 12.0. Results: The average of the importance of hospice volunteer's activities was 3.09 and the performance was 2.31, which was lower than the importance. There was a significant correlation between the importance and the performance (r=.487, P=.000). There were significant differences in total score of the importance, depending on religion, education, and period of hospice volunteer activity of subjects. There were significant differences in total score of the performance, depending on age, religion, and period of hospice volunteer activity of subjects. Conclusion: The importance of hospice volunteer's activities, perceived by hospice volunteers, was relatively high, however their performance didn't reach the level of the importance. Some characteristics of the volunteers influenced the perception of the importance and performance of the hospice volunteer's activities. The findings of this study are expected to provide useful information for the development of educational and management programs the hospice volunteers.

Purpose: This study is to explore the relationships among spirituality, death anxiety and burnout level of nurses caring for cancer patients. Methods: Participants were 210 nurses from a cancer hospital in Seoul. Data were collected from April until June 2012 and analyzed using t-test, one-way ANOVA, Scheffe's test, and Pearson's correlation coefficient. Results: The mean score for spirituality was 3.51 out of six. Among sub-categories, the one that scored the highest was the purpose and meaning of life, followed by unifying interconnectedness, inner resources and transcendence. The mean score for death anxiety was 3.22, and the sub-categories in the order of high score were denial of death, awareness of the shortness of time, pure death anxiety and fear of matters related to death. For the burnout, the mean was 4.10. Among sub-categories, highest mark was found with emotional exhaustion, followed by depersonalization and personal accomplishment. The spirituality level was negatively correlated with those of death anxiety and burnout. Death anxiety was positively correlated with burnout levels. Nurses with the higher spirituality level also had a higher level of education and experience of spiritual education, believed in the existence of God. In contrast, death anxiety and burnout levels were higher among those with a lower level of education, atheists, and for those who answered that religion has little influence on life. Conclusion: Thus, it is necessary to provide spiritual interventions for nurses who care for cancer patients to develop their spirituality, reduce death anxiety and prevent them from burning out easily.

The paper describes The Narrative Communication Model of Hope Seeking Intervention developed by the authors as an approach to help clients to have individually specific hope experiences. The Model is founded upon the existential conceptualization of hope that views hope as subjective, unique experiences of meaning and processes. The Model has been developed based on the findings both in the literature and the authors' work on the nature of hope and hope experiences and integrating the concept of hope as subjective meanings and experiences, the processes of story-telling and the concept of narrative configuration as a way to engage in person-specific experiences, and person-centered communication. The results of the experiences with the application of the model in a study are used to clarify the model further. The Model incorporating story-telling and narrative construction through person-centered communication is identified in three components-the story-telling, the narrative intervention, and the communication components. These components are processed as an intervention to culminate into person-specific hope experiences in which active participation of clients as the story-teller and of interventionist as the communicative facilitator is required to produce narratives of hope with individual specific thematic plots that become the basis for hope experiences. The application of the Model has shown positive outcomes in clients with successful seeking of own hope experiences. The success of the Model application seems to depend upon interventionists' understanding of the model and the competency with the application of person-centered communication strategies.

Purpose: To explore the meaning of prayer in Korean patients with end-stage cancer who profess Christianity or Buddhism, given the significant differences between these religions. Methods: The Colaizzi (1978) analysis method was employed. In-depth interview were performed with 13 participants (seven Christians and six Buddhists) who were admitted to a University-affiliated hospital in Korea. Results: The six categories emerged: 1) communication with God, 2) mind discipline, 3) spiritual growth, 4) mysterious experiences, 5) perception of death and after-life, and 6) various forms of prayers. Conclusion: The participants' prayer experiences were described in a religious context. Christians believed that prayer is communication with God while Buddhists regarded it as disciplining of minds. Despite some differences between the religious groups, a general meaning of prayer was a desperate desire to solve their health issues by relying on God or someone who is more powerful than themselves. They also experienced personal and spiritual growth through prayer. This study explains the phenomenon of prayer experiences and shows that prayer is an important coping mechanism.

Enzymes are widely used in industrial applications such as detergents, food, feed production, pharmaceuticals and medical applications and major contributors to clean industrial products and processes. To screen, identify, and characterize the enzymes the zymography techniques are routinely used. The zymography technique is a simple, sensitive, and quantifiable technique that is widely used to detect functional enzymes following electrophoretic separation in sodium dodecyl sulfate (SDS)-polyacrylamide gels. The method is a versatile two-stage technique involving protein separation by electrophoresis followed by the detection of enzyme activity in polyacrylamide gels under non-reducing conditions. It is based on SDS-polyacrylamide gel (PAG) copolymerization with substrates, which are degraded by the hydrolytic enzymes restored in enzyme reaction buffer after the electrophoretic separation. Any kind of biological sample can be applied and analyzed on zymography, including culture supernatants of microbes, plants extracts, blood, tissue culture fluids, enzymes in foods extracts and metaproteome. The advantage of zymography is that it is possible to directly detect the protein with activity on the electrophoretic gel as well as confirm the activity at the nanogram level. Thus, this zymography technology can be applied in various fields. However, these advantages are rather disadvantageous and can often lead to experimental errors. In this review, the advantages, disadvantages, and problem solving of zymography technique are described.

The purpose of the study was to investigate the perceptions of Elementary school teachers on mathematics instruction. To do this, 7 test items were developed to obtain data on teacher's perception of mathematics instruction and 73 teachers who take mathematical lesson analysis lectures were selected and conducted a survey. Since the data obtained are all qualitative data, they were analyzed through coding and similar responses were grouped into the same category. As a result of the survey, several facts were found as follow; First, When teachers thought about 'mathematics', the first words that come to mind were 'calculation', 'difficult', and 'logic'. It is necessary for the teacher to have positive thoughts on mathematics and mathematics learning, and this needs to be stressed enough in teacher education and teacher retraining. Second, the reason why mathematics is an important subject is 'because it is related to the real life', followed by 'because it gives rise to logical thinking ability' and 'because it gives rise to mathematical thinking ability'. These ideas are related to the cultivating mind value and the practical value of mathematics. In order for students to understand the various values of mathematics, teachers must understand the various values of mathematics. Third, the responses for reasons why elementary school students hate mathematics and are hard are because teachers demand 'thinking', 'because they repeat simple calculations', 'children hate complicated things', 'bother', 'Because mathematics itself is difficult', 'the level of curriculum and textbooks is high', and 'the amount of time and activity is too much'. These problems are likely to be improved by the implementation of revised 2015 national curriculum that emphasize core competence and process-based evaluation including mathematical processes. Fourth, the most common reason for failing elementary school mathematics instruction was 'because the process was difficult' and 'because of the results-based evaluation'. In addition, 'Results-oriented evaluation,' 'iterative calculation,' 'infused education,' 'failure to consider the level difference,' 'lack of conceptual and principle-centered education' were mentioned as a failure factor. Most of these factors can be changed by improving and changing teachers' teaching practice. Fifth, the responses for what does a desirable mathematics instruction look like are 'classroom related to real life', 'easy and fun mathematics lessons', 'class emphasizing understanding of principle', etc. Therefore, it is necessary to deeply deal with the related contents in the training courses for the improvement of the teachers' teaching practice, and it is necessary to support not only the one-time training but also the continuous professional development of teachers.
