Nowadays most companies are required to acquire the quality assurance system for their survival. It is essential to improvement company's competitive power that Certification of Quality Assurance System but there are many problems. To analysis the effects of ISO 9000 series/QS-9000 QA systems to the Domestic Company Quality Improvement as well as quality consciousness, data has been surveyed form quality assurance engineers who have work on certification activities. The data is analyzed using relevant tabulations of five scale or paired t test method in order to compare level of quality management of pre-certification with that of post-certification. It is analyzed in two parts which are qualitative effects and quality maturity grid. Also, to analysis for the bottlenecks and problems the data is analyzed using frequency analysis method.

In previous private education expenses were concentrated only on expenses for elementary, middle, and high school students. Therefore, it is difficult to understand the actual condition of preschool children's private education expenses. To solve this problem, we analyze the 2013 and 2020 data of the Korea Welfare Panel to confirm the private education expenditures of pre-school children. Also, we examine the differences and changes in private education expenditures according to household variables. We selected the household variable as the socio-demographic variable of the study subject. We defined the household variable as the area and income of the household. We show the actual results of private education expenses for household variables using frequency analysis, descriptive statistical analysis, t-test, and one-way ANOVA of SPSS 27.

This study attempted to identify the service satisfaction with the 119 emergency service and the factors that affect it based on the responses of subjects who used the service. Data collection was conducted from February 11 to March 11, 2021, using convenience sampling. A total of 1842 subjects who used emergency medical services using 119 ambulance in 2020 participated. For the collected data, frequency, percentage, mean, and standard deviation were calculated, and t-test, analysis of variance, and multiple regression analysis were performed using SPSS 23.0. Based on these results, to further enhance the satisfaction of users of the 119 emergency service and the quality of emergency medical services, it is important to improve the quality of paramedics through education and systems. In addition, to increase user satisfaction, efficient and systematic communication education is required.

Data were collected from February 7 to 18, 2022 from 232 nurses working at four military hospitals under the Armed Forces Medical Command. The analysis was conducted using the SPSS/WIN 26.0 program, and descriptive statistics, t-test, ANOVA, Pearson coefficient correlations, and multiple regression analysis were performed. Results: Factors affecting the intent to stay included job esteem (β=.44, p<.001), total clinical experience of more than 10 years (β=.24, p=.001), and nursing work environment (β=.17, p=.009). Conclusion: The results can be used to ensure personnel quality at military medical institutions and can contribute to improving patient safety and medical services. Further, nursing managers need to formulate and implement strategies to foster a positive nursing work environment.

The purpose of this study was to analyze of obstacle gait using spatio-temporal and foot pressure variables in children with autism. Fifteen children with autism and fifteen age-matched controls participated in the study. Spatio-temporal and foot pressure variables was investigated using GAITRite pressure sensor system. Each footprint was divided into 12 equal trapezoids and after that the hindfoot, midfoot and forefoot analysis was developed. Independent t-test was applied to compare the gait variables between the groups. The results showed that the autism group were significantly decreased in velocity, cadence, cycle and swing time compared to the control group. The autism group were significantly increased in step width and toe out angle compared to the control group. The autism group were significantly increased at midfoot and forefoot of lateral part of footprint and forefoot of medial part of footprint in the peak time compared to the control group. The autism group were significantly increased at midfoot and hindfoot in $P^*t$, at midfoot in active area, and at hindfoot in peak pressure compared to the control group. In conclusion, the children with autism showed abnormal obstacle gait characteristics due to muscle hypotonia, muscle rigidity, akinesia, bradykinesia and postural control impairments.

The advanced construction technology endorsement system(ACTES) has used the improper evaluation criteria. Because of its insufficiency of quantitative evaluation, it is difficult to attain the objective and fairness. This study used a survey to investigate a actual condition of ACTES. The survey found that ACTES needed a evaluation criteria and a quantitative evaluation method. In addition, This study proposes the evaluation model that uses a discriminant function. The model process consists of several phases that are brain storming, t-test and discriminant function analysis.

The purposes of this study were to investigate consumer's antecedent mood, cognitive factors, and experienced affection, to find out the relationships among antecedent mood, cognitive factors, experienced affection, and consumer's characteristics, and to examine the discriminant variables of apparel buying behaviors. We developed an questionaire based on the previous studies and pretests. We collected data from 443 housewives living in Pusan and analyzed by Factor analysis, t-test, and Discriminant analysis. The results showed as following: 1. Antecedent mood consists of four factors and cognitive factors in store were composed of four factors. Experienced affection in store includes Pleasure, Dominant and Stimulating feeling. 2. We discovered that consumer characteristics related to the antecedent mood, the experienced affection and cognitive factors in store. 3. Purchasers didn't relate to the consumer characteristics, and related to the antecedent mood, the cognitive factors, the experienced affection in store. Experienced affection and antecedent moods appeared to be important factors in determining apparel buying behavior of consumers. Especially, Pleasure and Dominance of the experienced affection and Depression, Excitation/expectation. Worry and Self-encouraging of the antecedent moods were more important variables in determining apparel buying behavior than any other variables.
