Several researchers in the early days have studied the concept of creativity and its definition, but with the emergence of an unprecedented infectious disease, creativity attracts more attention in the academic world these days. It is because the ability to respond to change and create something that did not exist before has become an essential competency for survival. Therefore, we proposes a creativity textbook that can be used for teacher training based on a creative education practical strategy model for the purpose of enhancing the creativity of teachers in the field through analysis of various prior studies on creative education. And also, we developed the textbook to teach the principles of information security using creative storytelling techniques. In the teacher training using the textbook, the survey was conducted with 40 questions consisting of originality, fluency, elaboration, synthesis and organization factors in order to confirm the change in the teacher's creativity, and all factors were significantly improved. The textbooks developed in this study are meaningful in that it has increased the utilization of teachers' field education. We hope that this thesis will provide implications for the development of creative fusion textbooks, and related research will be actively conducted in the future.

This study attempted to identify factors work environment that affect job satisfaction in dental hygienists. This study was conducted between August 29 and September 28, 2017, as part of an in-depth study of the 'Survey on the Working Environment of Clinical Dental Hygienists' of the Korean Dental Hygienists Association. To get the responses, the questionnaire was posted on the website of the Korean Dental Hygienists Association, and of the respondents, 4,663 were selected and analyzed. An independent t-test and one way ANOVA analysis were used to make a comparison of job satisfaction according to the general characteristics, salary, and tasks. Logistic regression analysis was conducted to identify factors affecting job satisfaction. The significance level was 0.05. In regard to salary information, the job satisfaction was found to be high (p<0.001) in cases where the salary was considered appropriate, when incentives were provided, when rewards or vacation expenses were supported, and when overtime and nightly work allowances were paid. In regard to job information, the job satisfaction was found to be high (p<0.001) when the volume of work was considered appropriate, when there were sufficient numbers in the workforce, and when the division of labor among the other personnel was clear. As a factor affecting job satisfaction of dental hygienists, the case of thinking that 'workload is appropriate' was found to be 2.052 times, showing the highest score. Job satisfaction in dental hygienists affects the turnover and has a significant effect on the performance of the organization. Therefore, it is believed, that it is urgent to improve the working environment such as salary and clear division of duties affecting job satisfaction of dental hygienists.

For Korean learners, writing is a harder part than any other areas in Korean languages. But in the future, the ability to organize and write systematically is essential for future koran languages learners to take classes, do assignments and presentations at school, and then adapt to job situations. Therefore, there is a need to devise a direction for this. In general, writing characteristics are viewed in many ways, including writing productivity, writing complexity, and writing errors. Accordingly, the study provided drawings and A4 paper for Vietnamese Korean learners, Chinese Korean learners, and Korean university students, before writing freely. Based on the their writing results, we looked at syntax factors (total C-units, total number of words), syntax complexity (number of words per C-unit and clause density), and writing errors (postposition, spell errors, and connective suffix, space errors) According to the study, Vietnamese and Chinese Korean language learners showed significantly lower syntax productivity and complexity than Korean university students, and showed more writing errors than Korean students in postposition and clause density. Based on the results of the study, we discussed writing guidelines for Korean languages learners. However, this study did not validate the differences in writing characteristics according to the Korean language level and length of residences for the study subjects. Therefore, it is necessary to consider this in future research.

Flux cored arc welding (FCAW), which is used widely in many fields, such as shipyards, bridge structures, construction machinery, and plant industry, is an alternative to shielded metal arc welding (SMAW). FCAW is used largely in the welding of carbon and alloy steel because it can be welded in all poses and obtain excellent quality in the field under a range of working conditions. In this study, the mechanical properties of welded parts were analyzed after different welding of SS400 and SM490A using FCAW. The following conclusions were drawn. The tensile test results satisfied the KS standard tensile strength in the range of 400~510 N/mm2 in all welding positions. The bending test confirmed that most of the specimens did not show surface breakage or other defects during bending and exhibited sufficient toughness, even after plastic deformation. The hardness test results were lower than the standard value of 350 Hv of KS B 0893. Similar to the hardness test, were greater than the KS reference value. The macro test revealed no internal flaws, non-metallic inclusions, bubbles or impurities on the entire cross section of the weld, and there were no concerns regarding lamination.

Many university students try to start up a lot because of career uncertainty, and this study reflected this environmental situation. The subject of the study is the degree to which subjective norms of university students affect the start-up intention. In addition, we looked at the mediated effects of self-efficiency and the moderated effects of security competence. To verify the hypothesis of the study, 201 university students in Seoul were asked about the relevant variables. And based on prior theory, hypotheses and questionnaires were made. In addition, the validity, reliability and correlation analysis of each variable were conducted. Multiple regression analysis was used for hypothesis analysis. As a result, subjective norms have a positive effect on the start-up intention. Next, self-efficiency was found to be mediating the relationship between subjective norms and start-up intentions. Finally, when subjective norms affect the start-up intention, security competence showed negative moderate effect. The implications of this study are as follows: First, a positive perception of start-up by those around them is needed when it comes to raising the intention of starting a business. This positive perception also affects the confidence and sense of challenge in start-up and affects their start-up intention. However, if career anchor prefer stable employment for the organization, it can be seen that they negatively affect the start-up intention.

A new nitric oxide-induced (NOI) gene was isolated by screening ESTs from a cDNA library of dehydration-treated fibrous roots of sweetpotato (Ipomoea batatas). The 720 bp cDNA fragment, IbNOI, was sequenced, from which a 77 amino acid residue protein was deduced. A search of the protein BLAST database identified significant similarity to other plant NOI protein sequences. Quantitative RT-PCR analysis revealed diverse expression patterns of IbNOI in various tissues of the intact sweetpotato plant, and in leaves exposed to different stresses. The IbNOI gene was highly expressed in storage roots and suspension-cultured cells. In leaf tissues, IbNOI showed strong expression during sodium nitroprusside (SNP)-induced NO accumulation and chemical stress treatments. Expression of IbNOI was also induced under various abiotic stress conditions, such as dehydration, salt, and bacterial pathogen infection. These results suggest that IbNOI is involved in plant responses to diverse abiotic stresses and pathogen infection through a NO-related pathway.

The present study investigates the relationship between social competence and economic performance in social enterprises. Social enterprises simultaneously pursue social value creation and economic value creation, two of which are not easily compatible each other. This study explores the conditions under which these two values can synergize with each other and thereby, positively affect each other's performance. In particular, I examine how two important social competences, that is, social identity and social alliance, influence economic performance of social enterprises. Using the secondary data on social enterprises from Korea Social Enterprise Promotion Agency, I run OLS regression analyses to test hypotheses. I find that investment on social value creation, only when it aligns with social identity, has a statistically significant and positive relationship with economic performance of social enterprises. Further, the study finds evidence that social alliance in and of itself does not affect economic performance of social enterprises. However, social alliance does have a positive influence on social enterprises' economic performance, only when taking into account social alliance partners' organizational attributes and a focal social enterprise's degree of readiness to absorb expected gains from social alliance altogether. The present study improves our understanding on social entrepreneurship research by suggesting how social enterprises can enhance two seemingly incompatible values in a simultaneous manner. I also discuss potentially fruitful future research agenda based on the present paper's findings.

Unlike benign tumors, malignant tumors are capable of metastasis, easy to relapse, poor survival, and low quality of life. In Korea, here is a tendency to treat the tumors collectively according to the General Principles of Cancer Chemotherapy(GPCC) of the Health Insurance Review & Assessment Service (HIRA). But recently, companion diagnostics(CDx) is recommended rather than unilateral medication because biomarker-based molecular diagnostics is possible to predict the drug response of patients before drug treatment. Not only domestic but also overseas Food and Drug Administratio (FDA) recommends the development of the CDx system at the stage of drug development to ensure the responsiveness and safety of medicines. In this study, I focused on the necessity of CDx development direction as well as CDx development status through literature review. Furthermore I also discussed CDx types according to the molecular diagnostic technology such as immunohistochemistry (IHC), polymerase chain reaction (PCR), in situ hybridization (ISH), and next-generation sequencing (NGS) not only in the approved CDx but also in the developing one by US FDA. And I suggested the technology issue of CDx development process such as a selection of molecular diagnostics at the time of release, a clear understanding of the CDx mechanism, and a convergence of drug with CDx development. The necessity of social insurance system also was proposed for CDx development.

The sinking of the M/V SEWOL in April 2014 was not a mere marine accident, but a marine catastrophe. This grim case developed into a social tragedy that impinged the national sentiment and communal integrity. It is imperative that thorough provisions and measures be outlined at the national level with regard to massive marine accidents, oil pollution, and natural disasters that might critically affect government affairs. Pivoting on "The Black Swan Theory," a concept of improperly rationalizing a national crisis based on uncertainties, this research assesses a variety of response strategies that minimize the national economic and social damage caused by a large-scale marine disaster. Along with the effort of minimizing any potential defects in each protective barrier, the "Black Swan Detection System of the Marine Disaster" needs to be incorporated to prevent cases wherein such defects lead to an actual crisis. Maritime safety must be systematically unified under a supervisory organization, and a structure for maritime crisis on-scene command and cooperation must likewise be established in order that every force on the scene of a marine disaster may act effectively and consistently under the direction of an on-scene commander.
