Nail art is a kind of nail painting or decoration that adds to the beauty. Throughout making nail art, the worker was on a dusty operation with the smoothing of chemicals and nails. People working at nail shops not only use a variety of chemicals, but also experience a lot of fine powder during the process of nail trimmings. While drying the chemical adhesive, the workers often complain of eye, nose and throat discomfort. In addition, the acrylic brush is characterized by a lot of smell when washed with washing solution. Also nail art workers directly influence the worker's breathing through the work done by placing the guest's hands in a work space called a nail table. Chemical ingredients used in nail art procedures include acetone, ethyl acetic acid, toluene, butyl acetic acid, glue, and top coating of nail varnishes. Prolonged inhalation of these substances may cause dizziness, vomiting, as well as impaired respiratory system. The purpose of this study is to investigate the respiratory symptoms of nail shop workers who are likely to be affected by work in nail shop and to find out which factors have the greatest influence if they have respiratory symptoms. Therefore this study is to provide basic data on the health management system of people engaged in nail shop and to develop health education program. For this study, the data collection was collected on July 7, 2017 for the nail shop workers attending the nail art trend seminar held in Gwangju, in Korea. The data were all 236. However, except for the poor data, 208 data were used for the final analysis. The questionnaire consisted of 30 in general questions, questions about self-efficacy in 24 questions. elf-efficacy measuring tool developed by A.Y, Kim, I. Y, Park(2001). The self-efficacy questionnaire consists of 24 items and is self-reported 7-point Likert scale. The reliability of this tool was cronbach alpha = .934.The collected data were analyzed using spss 18.0. Information of Research participant performed frequency analysis. To examine the effects of personal characteristics on self-efficacy, $X^2$ analysis was conducted. And also $X^2$ analysis was conducted to analyze the coughing symptom appearance according to individual and environmental factors. A hierarchical regression analysis was used to determine which of the personal and environmental factors influenced cough symptoms.

This study empirically analyzed the relationship with major influencing factors in enhancing innovation capability of start-ups and their influence on innovation performance. If the existing innovation competency studies were analyzed from a general corporate perspective, In this study, it was analyzed from the perspective of start-up companies with less than 7 years of founding. As a result of a survey on startups, learning competency among the sub-variables of innovation competency, R&D competency and marketing competency are significant positive (+) consistent with both organizational competence related to organizational culture and organizational goals, technology commercialization competency, and close product competency. Has been shown to affect. The technical competence part does not have a significant effect on the product competency. However, it could not be interpreted that the importance of these competencies was low. This is because although technical competence did not directly affect product competency, it was analyzed as a meaningful result in relation to R&D competency. In addition, the characteristics of the company were classified into technology orientation and market orientation, and the relationship between each sub-variable was analyzed. The technical competence of a technology-oriented company did not have a significant effect on the product competency, but it was found that it had an effective effect on the R&D capacity. It is also consistent with the research findings that the initial survival rate is low as the characteristics of start-ups are often based on technology and ideas. Based on these results, There is a difference in major innovation capabilities according to the growth stage of a company. From a practical point of view, I would like to present approaches and implications for strengthening the competence of start-ups.
ICT sector has been made a great deal of achievements for past 20 or more years in the aspects of the industrial promotion and the efficiency improvement under the strong leadership by the government for the informatization and still leads the Korean industries. However, the previous studies are mostly on how the quantitative growth of patents impacts a company's management achievements while being insufficient on the qualitative level. In this study, an analysis is attempted on the impact from the qualitative level of patents held by a ICT company leading Korean industry to its management achievements. In other words, if the concentration of technological innovation activities, a scale to measure the qualitative level of possessed patents is influential to the growth and the profit of a company is analyzed. The analysis result shows that the current time technological superiority index, RTA and the concentration index, CRn of the technological innovation activities significantly impact to the growth and the profit of company. This study demonstrates the positive impact from a highly qualitative level of patents to the growth and the profit of a company in ICT sector in the current circumstance of insufficient researches on the qualitative level of patents. Therefore, this study is expected to present a new start point for the future studies.

As an origin and a starting point of business start-up, this start-up intention is believed to be the driving force of economic growth. Being aware of the importance of the start-up intention, the study looked into cause-and-effect relationships of variables focusing on intermediate roles of start-up self-efficacy and intrinsic motivation in self-leadership and start-up intention of business founders. In order to achieve the research goal, the study conducted both a survey targeting a total of 195 business founders registered at a business incubation center and an empirical analysis on the results of the survey. According to the findings from the analysis, the study first learned that the self-leadership would have a positive effect on the start-up self-efficacy and the intrinsic motivation which eventually proved that the self-leadership is a leading variable of the start-up self-efficacy and the intrinsic motivation. Second, both the start-up self-efficacy and the intrinsic motivation were observed to be positively related to the start-up intention. That finding signified that roles of the start-up self-efficacy and the intrinsic motivation are important to increase the start-up intention. Third, intermediate effects of the start-up self-efficacy and the start-up intention were discovered from the self-leadership and the start-up intention, the main topics of the research. Hence, in order to improve the start-up intention, the importance of the start-up self-efficacy and the intrinsic motivation should be recognized and promoted as well and for this goal to be achieved, the business founders should understand the idea that the self-leadership has to come first than anything else in this case. Based on the results of the research, the study offers theoretical and practical implications.

This descriptive study investigated the factors influencing on subjective happiness of senior nursing students. The participants were 235 nursing students in grades 3 and 4 in K city from May 1, 2019 to May 28, 2019. The data was collected using self-report questionnaires that contained items on subjective happiness, professional intuition, human relationship, major satisfaction, family health, and social support scale. The data was analyzed using descriptive statistics, Pearson's correlation coefficients, and stepwise multiple regression analysis with the SPSS 22.0 program. The subjective happiness of the subjects averaged 4.75±1.16 on the 7-point scale, and the subjective happiness according to the general characteristics of the subjects showed a significant difference in health status (F=6.826, p<.001). The most influential factors on the subjects' subjective happiness were health status (β=.177 p=.005), academic satisfaction (β=.138, p=.027), and family health (β=.268, p<.001), and the explanatory power of the model was 16.7% (F=15.160, p<.001). The results of this study may provide a foundation to develop an efficient intervention program to improve the happiness of senior nursing students.
This thesis assumes that the teaching objective of the Probability unit of the 8th grade textbook under the 7th National Curriculum is to enhance the ability to analyze and utilize informations. And we examine them if this point of view is fully reflected. Based on the analysis of the textbook analysis, followings are found. 1) It is necessary to emphasize more enumerating all possible cases and to induce formulae counting the number of possible cases through organizing them 2) The probability is to be decribed more clearly as a likelihood of events and to be introduced and followed through various students' experiences and the relative frequencies. Less emphasis on probability computations, while more emphasis on probability comparisons of events are recommended. 3) The term "influential events"(a kind of stochastic correlation) is ambiguous. It is necessary to make clear what it means at tile level of the 8th grade or to discard it for it is to be learned at the 10th grade again. Especially, contingency table has been introduced at the 9th grade under the 7th National Curriculum. 4) Uses of the likelihood principle in making a decision and in learning the reliability of it should be encouraged. And students are to team the hazard of transitive inferences in probability comparisons. As a consequence of above, we feel that textbook authors and related stakeholder are to be more serious about the behavioral changes of students that may come along with the didactics of specific contents of school mathematics.
When communities of practice(CoP) was mostly informal, has been formulated. Because Knowledge management(KM) was emphasized in the business sector. So it increase interest in the COP. Since the early 2000s, the research interest has thus far grown. At a point in time has the subject, CoP, been researched for ten years, it is significant to review the literatures, the main topics as well as critical factors on the subject. In this study, the trends in the relevant researches and the performance factors from the previous studies are examined. The references for this study are limited to the authorized scholarly and scientific journals. The results therethrough processed show that total 37 researches were conducted between the year 2000 and 2012. These could be classified by the research methods as 16 case studies, 11 studies using CoP as the dependent variable, 4 studies using CoP as an independent variable and 3 theoretical discourses. 7 out of 16 case studies suggest the 14 success factors of CoP; the most influential performance factor is the external community support. 11 studies examined factors influencing the performance of CoP; 13 performance factors were proposed in these studies. The most significant factor influencing the performance of CoP is the team effectiveness.

The purpose of this study is to provide the newly developing ideas to compose an appropriate question and to point out the present problems in the utilization of survey result. It is very vital for the presidential preference not only to be a political achievement of the President himself, but also to be a influential base of people-related policy and its implementation. At first, it turned out to be inappropriate to make a question for the evaluation of presidential working performance in the perspective of questionnaire planning. As the respondents were not informed of what the President did, so they were more likely not to know whether the President did well or not. Secondly, the correlation analysis has been made between the evaluation question of the presidential working performance and policy-related questions including the direct one for the presidential preference in the aspect of statistical analysis. Through this process, the evaluation of the presidential working performance is not accountable and the direct question for the presidential preference is at best explainable. In conclusion, it seems more persuasive to compare the statistical outcome of the presidential preference which has been derived of to the high rating what the respondents think comprehensively not depending on a subjective decision by mass media.
With the aim of diagnostic research on health education. the health promoting behaviors related to elementary school students' weight control. life satisfaction. health state. self-efficacy. parent's interest and knowledge about weight control and school health education of weight control were investigated on the basis of the PRECEDE model. The data for this study were collected from a sample at an elementary school in Chongju for 5 days in July. 2004. In analyzing the data. t-test. one-way ANOVA. chi-square test and multiple regression analysis were done by using SPSS 10.1 The results were as follows : 1. The elementary school students' level of life satisfaction was above half of the full point. The score difference of life satisfaction was statistically significant by grade and academic achievement(F=4.646. p=.010. F=16.042. p=.000). 2. The perceived level of health state was moderate for all students. Normal weight students' level was significantly higher than obese students' (t=3.667. p=.000). 3. The perceived level of health promoting behaviors related to weight control was above the moderate. The perceived level of health promoting behaviors related to weight control in the obese students was significantly higher than that in normal weight students(t=-2.225. p=.027). The students used computer for 1.48 hours and watched TV for 2.52 hours a day. 4. The score of health promoting behavior self-efficacy in this subject was 70.61. 5. The parents' level of interest in the obese students' weight control was significantly higher than that in the normal weight students(t=-4.86. p=.000). 6. Sixty-six percent of the students learned about weight control education in school. 7. The health promoting behavior self-efficacy among the educational diagnostic variables was the most influential variable in students' health promoting behaviors related to weight control. This research diagnosed the needs of weight control education in elementary school by assessing various factors related to weight control behaviors. The research findings suggest that we can enhance the prevention of childhood obesity by strengthening the related factors such as parents' knowledge and interest, health promoting behaviors and self-efficacy related to weight control in school health education.

Concentrations of fine particulate matter ($PM_{2.5}$) and several of its particle constituents measured outside homes in Houston, Texas, and Los Angeles, California, were characterized using multiple regression analysis with proximity to point and mobile sources and meteorological factors as the independent variables. $PM_{2.5}$ mass and the concentrations of organic carbon (OC), elemental carbon (EC), benzo-[a]-pyrene (BaP), perylene (Per), benzo-[g,h,i]-perylene (BghiP), and coronene (Cor) were examined. Negative associations of wind speed with concentrations demonstrated the effect of dilution by high wind speed. Atmospheric stability increase was associated with concentration increase. Petrochemical source proximity was included in the EC model in Houston. Area source proximity was not selected for any of the $PM_{2.5}$ constituents' regression models. When the median values of the meteorological factors were used and the proximity to sources varied, the air concentrations calculated using the models for the eleven $PM_{2.5}$ constituents outside the homes closest to influential highways were 1.5-15.8 fold higher than those outside homes furthest from the highway emission sources. When the median distance to the sources was used in the models, the concentrations of the $PM_{2.5}$ constituents varied 2 to 82 fold, as the meteorological conditions varied over the observed range. We found different relationships between the two urban areas, illustrating the unique nature of urban sources and suggesting that localized sources need to be evaluated carefully to understand their potential contributions to $PM_{2.5}$ mass and its particle constituents concentrations near residences, which influence baseline indoor air concentrations and personal exposures. The results of this study could assist in the appropriate design of monitoring networks for community-level sampling and help improve the accuracy of exposure models linking emission sources with estimated pollutant concentrations at the residential level.
