Korean government has been implementing a smart grid testbed in Jeju Island for the low-carbon green growth. As smart grids are in the early stage of their diffusion, strategic guidelines and related measures are needed to spread them successfully. In general, the successful diffusion of new technologies or new products are mostly determined in its early stages. With the introduction of smart grids, the electricity market paradigm will be transformed into user-oriented from provider-oriented. Thus, a study on the diffusion of smart grids from the perspective of users is necessary. This paper examines factors affecting the adoption and diffusion of smart grids from users' perspectives and provide strategic guidelines for diffusing the smart grid. Researchers conducted in-depth interviews with 41 people who have been already using smart grids in the Jeju testbed. Semi-structured interviews were used to collect data. The interviews were recorded on a digital voice recorder memory and subsequently transcribed verbatim. A total of 133 pages of transcripts were obtained from about 10 hours interviews. 97 concepts, 47 sub-categories and 19 categories were identified through open coding of grounded theory. We suggested a paradigm model for diffusing smart grids and total of seven propositions as strategic guidelines.

Purpose: This study was conducted to define the experiences of nursing activities in Gwangju area during the May 18 (5 18) Democratic Uprising over 30 years ago. Methods: Data were collected in 2010 and 2011 through individual in-depth interviews. Ten nurses who worked in general hospitals in the Gwangju area during the 5 18 Democratic Uprising were interviewed using open-ended questions. Each interview lasted about 2~3 hours. Verbatim transcripts were analyzed using Van Kaam's method of phenomenological analysis. Results: Four categories emerged from the analysis: anxiety about the incident which was experienced for the first time; progress of the 5 18 events and relationship to participants; changes in nursing environment; retrospection and wishes related to the 5 18 incident. Conclusion: This oral history study revealed more clearly of the experiences of nursing activities in the Gwangju area during the 5 18 Democratic Uprising. The data may provide a basis for writing history nursing in the community, and can be a basis for guidelines covering nursing care in crisis.

Some fifty survivors participated in the narrative therapy sessions from March 2003 to December 2004, and thirty cases were analyzed using the transcripts. Each participant's surviving story was summarized, and then interpreted and reinterpreted by the survivors themselves in collaboration with the researcher. The two main principles in narrative analysis were hermeneutical distanciation and hermeneutical circulation. Result and Conclusion: First, nursing involvement should play active roles from the early stages of disaster incidents. Specifically, emergency nursing and flexible coping plans are to be available according to the specific properties of each case. Secondly, it is necessary to try to understand the extreme emotional experiences of disaster survival. The horror and pain people feel at an incident cannot simply be generalized, and it requires that each case be approached individually to help stop social alienation. Thirdly, more constant and long-term studies are required to set up nursing strategies for disaster survivors. Forming a trusting relationship with survivors is basic, and formally registering as participants is necessary for continuous interventions. Fourthly, we should deeply appreciate the danger and complexity of modern society and understand the complex nature of disaster. Fifthly, interdisciplinary activities and studies are necessary in combination with various other fields to establish a framework of total nursing care for disaster incidents. Lastly, it is urgently necessary to educate families and friends of the survivors and the society as a whole about life after a disaster.

Description of the phenomena of interest by the reader. 2. collection of subject's description of the phenomena, 3. Reading all the subject's descriptions of the phenomenon, 4. Returning the original transcripts and extracting significant statements, 5. Trying to spell out the meaning of each significant statements, 6. Organizing the aggregate formalized meanings into clusters of themes. 7. Writing an exhaustive description, 8. Returning to the subjects for validation of the description, 9. If new data fare revealed during the validations incorporating them into an exhaustive description. The participants in this study were eight are nurses working for clinics. This strategies for data collecting were needed : deep face to face interview. Results : 6 cluster of themes are : 1. the heavy pressure, 2. the pride and the royal summons, 3. the powerlessness, 4. the hope, 5. the tiresome. 6. the distressed feeling. Conclusion : The results of the this study would help us to understand nurses in clinics, make direction for nursing education, and identify need for continuing inquiry.

Purpose: The purpose of the study was to identify and explain the essences and structures of maternal conflicts in Vietnamese married immigrant women in Korea. Methods: A phenomenological methodology was used for the study. Eleven Vietnamese married immigrant women participated in the study. Verbatim transcripts were analyzed using Colaizzi's method. Results: Four categories, 10 clusters and 26 themes emerged from the data for the experience in maternal conflicts of Vietnamese married immigrant women. The four categories were 'An unprepared young motherhood in another culture', 'Feeling left out of the mother's place along the bands of Nap tai tradition', 'My image is like not-being able to stand alone/be independent' and 'Finding hope in motherhood despite of conflicts and stigmas'. Conclusion: Vietnamese married immigrant women experienced not only the negative aspects but also sublimation of maternal conflicts. Based on the results, health professionals need to develop effective nursing interventions toward a positive maternal identity and approach with interculturalism for the Vietnamese married immigrant women in Korea.

Purpose: This ethnographic study was conducted to explore and understand the meaning of the daily life of nurses in emergency departments. Objectives for this study were to identify and describe the true nature of emergency room nurses' daily experience and create a theoretical model based on the findings. Methods: Data were collected through in-depth interviews and participants observation. These data were recorded and transcribed verbatim with consent of the informants, 10 nurses who had cared for patients in emergency rooms. Data were collected between November 2013 and October 2014. Interviews continued until no new information could be identified from transcripts. Data were analyzed using the taxonomic analysis method developed by Spradley. Results: Based on the data acquired from interviews, nurses' cultural domains were classified as 'extensity of emergency room nurses', 'temporality of emergency room nurses', 'relationships among emergency room nurses' and 'becoming an emergency room nurses'. Conclusion: The daily culture of emergency room nurses could be summarized as 'busy daily life amidst confusion'. However, many nurses boosted their self-esteem by taking care of patients' collaboration with fellow nurses. In other words, nurses in emergency room forms a dynamic culture and pursue professionalism, rather than a simple chaotic daily life culture.

Three assay methods for quantification of the two galactose-operon mRNAs that only differ by 5 bases in their 5'-end are presented. The 5' ends of each mRNA were extended by ligating the 3'-end of the abundant 5S rRNA. This ligation extends the 5' ends of the two gal mRNAs long enough to be distinguished by the specific PCR primers in the following quantification reactions. Quantification of the corresponding cDNAs was performed either by primer extension assay or real-time qPCR. To circumvent the problem of the RNA ligation reaction (i.e. very low ligation efficiency), we devised a new method that employs real-time qPCR directly for the quantification of the gal transcripts which differ by 5 bases in their 5'-ends.

Environmental and anthropogenic changes affect the health and stability of marine ecosystem. In this study we aimed to identify molecular biomarkers for ecotoxicological pollutants risk assessment in the rockfish (Sebastes schlegeli). We designed primers based on conserved sequences by multiple alignments of target genes from related species, and cloned the partial cDNAs of cytochrome P450 (CYP1A1), glutathione S-transferase (GST), metallothionein (MT), superoxide dismutase (SOD), ubiquitin (UB), vitellogenin (VTG) and $\beta$-actin by reverse transcription polymerase chain reaction (RT-PCR) from S. schlegeli. Northern blot results indicated that these six genes expressions were significantly induced by benzo[a]pyrene (BaP, 1 ${\mu}M$) and that the level of each of their transcripts increased in BaP-exposed rockfish in a time-dependent manner. This study suggests that transcriptional changes in these six genes may be used for monitoring environmental exposure to polycyclic aromatic hydrocarbons (PAHs).

The global regulator, GacS (global antibiotic and cyanide sensor kinase), was required for the increased resistance to hydrogen peroxide occurring as cultures of the rhizobacterium, P. chlororaphis O6, matured. Specific stationary-phase peroxidase and catalase isozymes were absent in the GacS mutant, whereas a manganese-superoxide dismutase isozyme was expressed earlier and to a great extent than wild type. In the wild type cell, transcript accumulation of rpoS was higher in late logarithmic-phase cells than cells from mid logarithmic- or stationary-phase. Transcripts from rpoS in the GacS mutant were reduced in each of these growth phases compared to the wild type expression. The down stream sequence from rpoS lacked sequences encoding a small RNA, rsmZ, found in other pseudomonads and implicated in control of genes activated by the GacS system. These findings suggest that GacS-mediated regulation of RpoS plays role in control of oxidative stress in P. chlororaphis O6 by as yet an unknown mechanism.

The purpose of this study was to describe the elementary teachers' teaching behavior procedure in verification-type laboratory instructions. In order to do this, we should know first what constituted the teaching behavior elements in the teachers' instructions, before the teaching behavior can be analyzed. Thirty sets of instructions were recorded and their transcripts were used in this study. The results of this study indicated that the number of teaching behaviors numbered twenty four in total, and that the teaching behaviors could be classified into nine categories, and finally the procedure used in verification-type laboratory instructions generally followed seven steps. These steps can be described as follows; reminding subjects of the preliminary learned concept, presenting inquiry type questions or introducing the main concept, explaining the method used or presenting the predictable outcome/matter for verification, performing lab-based activities, presenting the outcomes, applying the main concept, and finally closing the instruction. For the purpose of promoting more authentic scientific inquiries using these types of instructions, the authors's claims were discussed.
