  • Despite that Korea has tried radical efforts in the global flow of regulatory reform in the past twenty years, the result was not radical at all, but rather disappointing. One examines the possibility of paradigm shift in regulatory reform based on new theoretic perspectives. Regulatory reform, one argues, is not just a neo-liberal approach to cut off overflowing regulation. It is a highly conflictual struggle in state order to move from industrial age paradigm to service age paradigm. In the process of the great shift states become integrated into the world of life constructed by the exercise of civil rights. The relation between the civic socio-economic life and the state apparatus became totally different. Past effort for deregulation missed this point without correct recognition of the role of civil freedom and rights in service economy. One treats three typical forms of regulation whereby conventional rules and regulations effectively damper the development of services: reciprocal perspective in contract management, industrial mind in urban and spaces design, and old way of human capital management. According these analyses a new initiative of regulatory reform is proposed to take place at the National Assembly.

  • To investigate molecular phylogenetic relationships and to test hypothesis of hybrid origin of Ranunculus cantoniensis (Ranunculaceae), the sequences of nrDNA and chloroplast DNA were analyzed for 8 taxa and 25 accessions including 5 accessions of outgroup. In the phylogenetic trees by analyses of maximum parsimony and maximum likelihood for ITS nrDNA sequences and combined data of psbA-trnH, rps16 and trnL sequences of cpDNA, R. cantoniensis was most closely related to R. chinensis, and then to R. taciroi and R. silerifolius. The molecular phylogenetic relationships were not congruent with the previous report that R. cantoniensis was most closely related to R. silerifolius. In the sequence analysis of ITS and psbA-trnH, rps16, trnL for R. cantoniensis and the related taxa, R. cantoniensis showed polymorphism. It supported that the polymorphism also was reported in chromosome number and karyotype of R. cantoniensis. Ranunculus cantoniensis shared the marker gene of R. chinensis and R. silerifolius in ITS, and one of R. silerifolius in cpDNA. These results supported the hypothesis that R. cantoniensis was caused by hybridization between R. chinensis and R. silerifolius based on chromosome number and karyotype, and also estimated that R. silerifolius might be of maternal origin and R. chinensis be paternal.

  • Maleic anhydride-grafted-polypropylene(PP-g-MA) were used as a blend component and a compatibilizer, respectively, for two reactive blends of polyamide 66(PA 66)PP-g-MA binary blends and PA 66/polypropylene(PP)/PP-g-MA ternary blends. The goal of this work was to investigate the property differences between binary and ternary blends. Tensile strength, flexural modulus, heat deflection temperature, impact strength, melt flow index, and the dependence of melt viscosity on the shear rate were examined. The impact strengths of binary blends were higher than those of ternary blends at all compositions, since the in situ synthesis of PP-g-PA 66 copolymer through the imide formation between the amine end group of PA 66 and the anhydride group of PP-g-MA gave the increase of molecular weight and was more popular in binary blends than in ternary blends. In case of ternary blends, most of the properties were superior to those of binary blends, owing to the better properties of PP compared with PP-g-MA. The toughened binary blends with 70/30(PA 66/PP-g-MA) and 80/20 ratios were not commercially applicable due to their poor processibility. So, the ternary blends which showed lower melt viscosities were recommended for the commercial applications.

  • Purpose : This study aimed to present the incidence of pressure ulcers and identify different associated factors according to the time of occurrence of pressure ulcers in intensive care unit (ICU) patients. Methods : The participants were 313 patients who reported pressure ulcers among 2,908 patients in ICUs at a large tertiary hospital in Gyeonggi-do. Among them, 220 patients (70.3%) had a pressure ulcer before admission, and 93 patients (29.7%) reported newly developed pressure ulcers after admission to the ICU. Data were collected between August 2018 and April 2019. Along with the time of occurrence and characteristics of pressure ulcers, diverse associated factors were gathered through electronic medical records. Data were analyzed using descriptive statistics, independent t-tests, and 𝑥2-tests. Results : Different risk factors associated with pressure ulcers in ICU patients according to the time of occurrence were main diagnosis, score of acute physiology and chronic health evaluation, score of Richmond agitation sedation scale, level of consciousness, administered sedatives, use of a ventilator, insertion of a feeding tube, and the duration of fasting period. Conclusion : Based on the results of this study, healthcare providers, especially ICU nurses, should try to detect early signs and symptoms of pressure ulcers, taking into account the derived factors associated with pressure ulcers in ICU patients. Practical intervention programs and strategies considering the factors associated with pressure ulcers must be developed to prevent and alleviate such ulcers in ICU patients in the future.

  • Because the educational significance of reading activities for growing children is so great, the importance of reading cannot be overemphasized. While the reading volume of elementary school students in Korea is very high, as they go up to middle school, the reading volume falls rapidly. This study examined a more effective way to resolve this middle school reduction in reading volume. Middle school freshmen were surveyed on their reading habits and preferences in the sixth grade of elementary school, after which the groups were divided into two groups based on their averages; groups with high/low reading habits and groups with high/low reading preferences). Participants also wrote reading reports for six weeks, kept a record of the days of the week they read for more than 20 minutes, and noted down the time they read in minutes. It was found that 75% of participants did not read one book a week when in the sixth grade of elementary school and it was confirmed that reading many books and liking to read were elements that had different dimensions. For example, about 35% of the participants said they liked books but rarely read them. It was also confirmed that the reading habits formed in elementary school were a strong variable that affected the number of days that and the reading time of middle school students rather than the reading preferences formed in elementary school. This study concluded that a subjective attitude toward reading and actually reading were completely different problems, which suggested that 'habits' could have a greater influence than 'preferences' when performing tasks to achieve goals.

  • The purpose of this study is to examine the effect of physical health on oral health in university staff and the mediating effect of stress on their relationship. As for the research method, a questionnaire survey was conducted from June 15 to June 30, 2021 for some university staff in the Seoul area. As research tools, general characteristics, somatic symptoms, oral symptoms, and perceived stress were investigated. For the analysis method, Pearson correlation analysis was used to examine the correlation between physical symptoms, stress, and oral symptoms, and regression analysis was used to verify the mediating effect. As a result, somatic symptoms, stress, and oral symptoms all showed a positive correlation. Also, somatic symptoms were found to have an effect on oral symptoms, and stress had a partially mediating effect on the relationship between somatic symptoms and oral symptoms: somatic symptoms directly affect oral symptoms, and stress directly and indirectly affects oral symptoms. In conclusion, institutional measures are needed to reduce the work stress of the university staff, and regular oral health education to promote oral health should be expanded.

  • The purpose of this study is to identify the factors that influence the nursing students' nurse image and professional self-concept on career exploration. This study was accomplished on 153 students in the 2nd, 3rd and 4th grades of the Department of Nursing Science at a college in area Y, and data were collected from July 1 to August 31, 2020 using a structured questionnaire. Measurement tools consisted of nurse image, professional self-concept, and career exploration behavior. Data processing was performed using the SPSS 22.0 program where general characteristics were analyzed by t-test, ANONA and post examination tests by Scheffe's test, using mean score, standard deviation, Pearson's correlation, and stepwise multiple regression. Nursing students' nurse image, professional self-concept, and career exploration behavior were all found to have significant positive correlations, and the most influential variable was professional self-concept. As for the total explanatory power of these variables, model 2 showed 25% explanatory power, which was increased by 2% compared to model 1. Based on this result, it is necessary to develop education and a career exploration action program which can improve the nurse image and professional self-concept.

  • It is very important to use the raw material in a particular field of research or education. Research without raw materials are difficult to prove and often remain hypothesis. The use of the raw material is also important in area studies that study specific areas. However, research of area studies, especially Western history, raw material and historical archives are very important data, but it is difficult to obtain and refer to these data due to physical or spatial constraints. In order to solve this problem, there is a method of collecting and providing historical archives, but it is currently difficult to find a case of providing overseas historical archives as a web system in Korea. Accordingly, in this paper proposes the necessity of collecting historical archives, the method of collection, and the method of digital archiving of collected data structurally and systematically. In this regard, investigate the existing research cases on the archive system and database design, and it description the differentiation between the existing systems and the modeling method proposed in this study. Also, to improve the efficiency of the search, it proposes a method of adding a tag table when database modeling.

  • This review aims to identify the virtual reality (VR)-based home modification programs and provide basic data for the future development and application of domestic VR-based home modification programs. We collected the studies of academic publication or conference, symposium addressed VR-based home modification from January 2011 to June 2021 using hand searching and databases such as Medline, Embase, and Scopus. A total of 7 studies were selected through selection criteria, and the studies were quantitative and qualitative studies on the development of VR prototype for home modification and the acceptability and usability of the programs. VR-based home modification have been developed and applied for various purposes for stakeholders involved in home modification. It can be used as the tools for fostering experts in home modification, evaluating the home environment remotely, and facilitating communication and collaboration with the stakeholders in the modification process. In the future, studies on development and feasibility of VR-based home modification program reflecting the characteristics of domestic housing should be conducted, and it is expected to be utilized as a tool to support the home modification process.

  • The study was initiated to identify the causes of physical and mental harm to workers and provide basic data. It is an analysis study using raw data from the 5th Working Environment Survey, and the study analyzed the impact of gender, verbal violence, insults, sexual harassment, sexual interest, and bullying on working environment satisfaction. Most of the victims' sexual harassment offenders were their coworkers (83.6 percent), and it was confirmed that women experienced more damage from bullying and sexual interest than men. Insult and verbal abuse have been identified as factors that reduce working environment satisfaction. Based on this study, we hope to improve productivity and work-life balance as well as improve workers' satisfaction with the working environment as a program that takes into account workers' influence factors.
