Sorting cut roses according to quality is very essential to increase the value of the product. Many factors are involved in determining the grade of cut roses: length, thickness, and straightness of stem, color and maturity of bud, and extra. Among these factors, the stem straightness and bud maturity are considered to be difficult to set proper classification criteria. In this study, a prototype machine and an analysis procedure were developed to grade cut roses according to stem straightness and bud maturity by utilizing color image processing and neural network. The test results indicated 15.8% classification error for stem straightness and 10.0% for bud maturity.

This study was carried out to evaluate the correlation between shear force determined by tenderness analyzer and grade decision factors consisting of yield grade (carcass weight, ribeye area, backfat thickness) and quality grade (meat color, fat color, marbling, maturity, texture) in a total of 200 Hanwoo cows. Results showed that there was a negative correlation between shear force and yield grade (r=-0.186, p<0.01), i.e., when the grade of carcass yield increased (A score), the shear force value decreased. Shear force scores showed a significant correlation with marbling scores (r=-0.19, p<0.01), but no correlation with scores of meat color, fat color and texture. The maturity of Hanwoo cows is known to be one of the major factors for evaluating the grade, and the maturity showed no significant correlation with shear force value (r=-0.05, p>0.05). It is possible to get useful information for evaluating the grade of Hanwoo cows if further studies addressing the correlation of water holding capacity, juiciness, taste and overall acceptability with maturity are carried out.

The purpose of this study was to make a comparative analysis of dietary habits, snacks, eating out and fast-food intake between students with a relatively early sexual maturity and others with a relatively late sexual maturity in a bid to grasp the impact of dietary behaviors on sexual maturity. The subjects in this study were 565 boys and girls who resided in Seoul and Gyeonggi province. They included fifth- and sixth-grade school children and seventh-grade middle school students. To classify the selected students according to the level of sexual maturity, the students of the same month age were divided into two groups in consideration of the stage of their sexual maturity and that of the other age groups. The early mature group was significantly taller and weighed more than the late mature group irrespective of gender. According to Tanner stages, the boys of the early mature group reached a 3.03 stage of sexual maturity when the sexual organs were taken into account, and those of the late mature group reached a 1.50 stage of sexual maturity. The girls of the early mature group reached a 3.43 stage of sexual maturity on the basis of breast, and those of the late mature group reached a 2.73 stage of sexual maturity. Concerning eating out, the early mature group ate out more frequently than the late mature group. In regard to snacks, the early mature group had a snack more often. The findings of the study indicated that there were differences in physical development and some dietary behaviors according to sexual maturity. The early mature group had a snack and ate out relatively more often than the late mature group, which showed that some dietary behaviors had an impact on the sexual maturity of the teens who arrived at the age of puberty.

Quality sorting of cut flowers is very essential to increase the value of products. There are many factors that determine the quality of cut flowers such as length, thickness, and straightness of stem, and color and maturity of bud. Among these factors, the straightness of stem and the maturity of bud are generally considered to be more difficult to evaluate. A prototype grading and sorting machine for cut flowers was developed and tested for a rose variety. The machine consisted of a chain-drive feed mechanism, a pneumatic discharge system, and a grading system utilizing color image processing and neural network. Artificial neural network algorithm was utilized to grade cut roses based on the straightness of stem and maturity of bud. Test results showed 89% agreement with human expert for the straightness of stem and 90% agreement for the maturity of bud. Average processing time for evaluating straightness of the stem and maturity of the bud were 1.01 and 0.44 second, respectively. Application of neural network eliminated difficulties in determining criteria of each grade category while maintaining similar level of classification error.

This study examined differences in beauty majors' career maturity and career decision-making depending on the grade and analyzed the relationship between the career maturity with the career decision-making to present basic data for guidelines that would help any relevant field with their career consultations and education targeting those students majoring in beauty at college. A total of 336 beauty majors in the metropolitan area were selected as the research subjects. The study confirmed that the higher the grade, the greater the career maturity. The students who had a higher level of career maturity tended to be included in the reasonable career decision-making category while those students with a lower level of career maturity were determined to conduct dependent decision-making. In terms of the career decision, the students in the higher grades were reasonable enough to make decisions logically because they collect various information through systematic stages but when it comes to the students in the lower grades, they were divided into the intuitive type that would reach a decision through emotional self-recognition depending on how one feels at this moment or what situation one is going through as well as the dependent type that would let people or environments influence one's decision-making. The grades of the students tended to cause differences in the career maturity and the career decision-making, and the significance between the two variables was proven. If the relevant fields carry out systematic grade-focused programs and career guidance not only to improve the career maturity of even the lower graders but also to encourage the students to make reasonable decisions, such programs and career guidance will be a help when the students try to determine a career.
