The purpose of this study is to identify the perceptions of and willingness for marriage among people in their 20s and 30s. The data came from the Korean General Social Survey of the Survey Research Center at Sungkyunkwan University. The sample data set included 292 men and women aged 20 to 39. The major findings are as follows. First, gender, satisfaction with one's household economic conditions, and significantly affect the individuals' perceptions of marriage. The results show that the men's education level, value of family succession, value of gender roles, and value of parents' role are the significant factors that affect their perceptions of marriage. In the case of the women's perceptions of marriage, the significant factors are their household economic conditions, value of family succession, value of gender roles, and value of childbirth. Second, the willingness for marriage among unmarried people is decided by age, education level, whether one has an income or not, satisfaction with one's household economic conditions, and value of one's childbirth. Overall, gender is the most significant factor that affects the perceptions of marriage among all the other variables. However, men's and women's values of gender roles and family succession, respectively, both significantly affect their perceptions of marriage but show opposite coefficient directions. Another finding shows that unmarried people who are willing to marry tend not to have children. This implies that they do not perceive the decision on having a child as a necessary factor behind marriage decisions.

The informations concerning knowledge, value and consumption pattern for rice foods of elementary schoolchildren (630 boys and 550 girls in 5th or 6th grade) were investigated in Changwon and Gimhae of Gyeongnam province. They were asked based on knowledge, one’s value and intake frequence of rice foods by questionnaries. Menus for 3 days including 2 weekdays and 1 weekend day were taken from 136 students (77 boys and 59 girls) in two Elementary Schools in Changwon and Gimhae to know intake reality of rice product. The purpose of this survey was to find the way of encouraging rice intake and preference which now seemed to be low because of simplified, westernized eating habits, and to provide basic information needed for inheriting and improving our traditional cooked rice centered eating culture. The results are summarized as follows. The knowledge of rice was positively correlated to the one’s value (r=0.365, p<0.001) and the preference (r=0.132, p<0.001), the one’s value was positively correlated to preference (r=0.409, p<0.001). The score of knowledge for rice was 12.8 points out of 20, the girls get points(13.12) significantly higher than the boys (12.53) (p<0.01). One's value about rice foods was 37.35 points out of 50 what is relatively high. They have eaten cooked rice type food for 2.24 times per day. Both boys and girls in Changwon and Gimhae area were having cooked rice type food significantly more during weekdays compared to weekends (p<0.001) by 3 days food record. According the results, we can see the possibility that schoolchildren can be encouraged to eat more rice foods by nutritional education to go with the development of various programs.

In this paper, we consider the multi-point boundary value problems for one-dimensional p-Laplacian at resonance: $({\phi}_p(x'(t)))'=f(t,x(t),x'(t))$, subject to the boundary value conditions: ${\phi}_p(x'(0))={\sum}^{n-2}_{i=1}{\alpha}_i{\phi}_p(x'({\epsilon}i)),\;{\phi}_p(x'(1))={\sum}^{m-2}_{i=1}{\beta}_j{\phi}_p(x'({\eta}_j))$ where ${\phi}_p(s)=/s/^{p-2}s,p>1,\;{\alpha}_i(1,{\le}i{\le}n-2){\in}R,{\beta}_j(1{\le}j{\le}m-2){\in}R,0<{\epsilon}_1<{\epsilon}_2<...<{\epsilon}_{n-2}1,\;0<{\eta}1<{\eta}2<...<{\eta}_{m-2}<1$, By applying the extension of Mawhin's continuation theorem, we prove the existence of at least one solution. Our result is new.

So many patterns of the clothing give the specific indication for one's clothing behavior and present the common style for the society. Human being gives the one's free expression and attempts to change the existing cultural environment by the clothing even though human being would be restricted in choosing the clothing within the category of the society & the culture. The value of human being which attempts to escape the restriction through the behavior theory of T. Parsons is analysed and studied. The role of the modern society is being transformed and human being attempts to express one's self through the clothing very strongly. The clothing behavior means the expression of oneself for others. This phenomenon comes from the changing of human being's view of value through the social & cultural environment which give human being the freedom of the individual to choose the various clothing.

A company's market value-added, which equals the excess of a company's market capitalization over it s book value, is used as one of the measures for intangible assets valuation in accounting literature. One problem with the approach is that the valuation results are affected by severe fluctuations in capital markets. In this paper, we propose an approach using the Kalman filter for intangible assets valuation. We apply this method to data of Korean electronic companies.

Let p be an odd prime and c be a fixed integer with (c, p) = 1. For each integer a with $1{\leq}a{\leq}p-1$, it is clear that there exists one and only one b with $0{\leq}b{\leq}p-1$ such that $ab{\equiv}c$ mod p. Let N(c, p) denote the number of all solutions of the congruence equation $ab{\equiv}c$ mod p for $1{\leq}a$, $b{{\leq}}p-1$ in which a and $\bar{b}$ are of opposite parity, where $\bar{b}$ is defined by the congruence equation $b{\bar{b}}{\equiv}1$ mod p. The main purpose of this paper is using the mean value theorem of Dirichlet L-functions and the properties of Gauss sums to study the computational problem of one kind mean value function related to $E(c,p)=N(c,p)-{\frac{1}{2}}{\phi}(p)$, and give its an exact computational formula.

The investigate the effect of fiber orientation on the interlaminar fracture toughness of carbon fiber reinforced plastics three prepregs which are domestic products are used in this paper. Those are used for the unidirectional composites, but only one is used for the cross-ply laminate composites which is molded $[0/90]_{6s},\;[0/45]_{6s},\;and\;[0/45/90]_{4s}$. The specimens used for the mode I and mode II Tests are DCB and ENF samples are examined by scanning electron microscope(SEM). The value of $G_{IC}$ is almost same when modified three calculating methods are applied. The highest value of $G_{IC}$at crack initiation is obtained at the $[0/90]_{6s}$ interlaminar and the lowest one is at the $[0/45/90]_{4s}$ interlaminar. The highest value of $G_{IIC}$ at crack initiation, however, is obtained at the $[0/90]_{6s}$ interlaminar and the lowest one is at the $[0/45]_{6s}$. The photographs of SEM show a difference behaviour between mode I and mode II fracture surface.
