Due to the fast changing social and physical environment, the clothing behaviour of elementary school students should have been changed. Since previous research was completed a long time ago, new research must be conducted to understand the relationships of the clothing behaviour of elementary school students in terms of the time of research, gender and grades. Third and sixth grades in Susan were sampled in 2002; the secondary data in 1988 was used. Factor analysis and Lisrel's group analysis were conducted. The results indicated as follows: 1. As there was an increased interest in clothes, the comfort of the clothes was decreased at the higher grades in 1988, and the low and high grades in 2002, and the clothes of boys in high grade increased in the manageability in 2002, but nor with boy students in the low grade neither all types of students in 1988. 2. As there was an increased manageability in clothes, all types of girl students became more independence in choosing their own clothes. However, boy students in the low and high grades only increased their independence in choosing their own clothes in 1988. 3. As there was an increased comfort of clothes, there was not a significant relationship with the independence of students for choosing their clothes concerning the gender, the grades and the period of research. 4. As there was an increased interest in clothes, the low grade girl and boy students in 1988 increased in their independence in choosing their clothes. However, the high grade boy students in 1988 significantly decreased their independence. Thus there are different results in the clothing behavior in the elementary school student concerning the time of study, gender and grades.

After a longitudinal analysis of the data on the college entrance examination of students enrolled in the Department of Chemistry Education at Gyeongnam from 2014 to 2021, the effect on the academic achievement of general chemistry according to the type of college entrance examination was studied. And the impact on the academic achievement of general chemistry according to the type of admission screening in face-to-face and non-face-to-face teaching-learning was also studied. As a result of analyzing the academic achievement of general chemistry by admission process, students admitted through occasional screening showed relatively high grades of A and B at 88.7%, and the ratio of grades of 1~3 of chemistry I in high school was high. On the other hand, in the case of students admitted through regular admission, the ratio of grades of A and B in general chemistry was very high at 94.3%, and the ratio of grades of 3~4 in chemistry I of the College Scholastic Ability Test was high. As a result of analyzing the academic achievement of general chemistry by class type and admission process, it was found that the grades of chemistry I by face-to-face classes had an effect on the academic achievement of general chemistry in non-face-to-face classes. In both admissions, the academic achievement of general chemistry by face-to-face classes was relatively higher than that of non-face-to-face-to-face classes.

The influences of the basic academic skills to the scholastic achievement grades has been researched and we made a test of the basic academic skills(Korean language, mathematic, foreign language) to the students of engineering department in I college in Seoul and analyzed the correlation between the basic academic skills and the scholastic achievement grades. Results show that the scholastic achievement grades has a correlation(r=.456, p<0.01) to the average grade of the basic academic skill test. High level students of the scholastic achievement grades have a correlation(r=.292, p<0.01) to the mathematical department and the others have a correlation(r=.232, p<0.05 and r=.279, p<0.01) to the Korean linguistic department. The results of this study through multiple regression analysis indicate that the scholastic achievement has a relation on Korean language skill. As a result, It is recommendable that the mathematical basic academic skill programs are suggested to the high-level students of the scholastic achievement grades and the linguistic basic academic skill programs to the others. Also, the required basic linguistic subject is needed to the low-level students of the basic academic skills and in this paper, we propose the test and management system for the basic campus-life skills including the basic academic skills and the basic major skills.

New product development (NPD) is defined as the transformation of a market opportunity and a set of assumptions about product technology into a product available for sale. Managers charged with project selection decisions in the NPD process, such as go/no-go choices and specific resource allocation decisions, are faced with a complicated problem. Therefore, the ability to develop new successful products has identifies as a major determinant in sustaining a firm's competitive advantage. The purpose of this study is to develop a new evaluation model for NPD project selection in the high -tech industry using support vector machines (SYM). The evaluation model is developed through two phases. In the first phase, binary (go/no-go) classification prediction model, i.e. SVM for high-tech NPD project selection is developed. In the second phase. using the predicted output value of SVM, feasibility grade is calculated for the final NPD project decision making. In this study, the feasibility grades are also divided as three level grades. We assume that the frequency of NPD project cases is symmetrically determined according to the feasibility grades and misclassification errors are partially minimized by the multiple grades. However, the horizon of grade level can be changed by firms' NPD strategy. Our proposed feasibility grade method is more reasonable in NPD decision problems by considering particularly risk factor of NPD in viewpoints of future NPD success probability. In our empirical study using Korean NPD cases, the SVM significantly outperformed ANN and logistic regression as benchmark models in hit ratio. And the feasibility grades generated from the predicted output value of SVM showed that they can offer a useful guideline for NPD project selection.
