This study investigated trajectories of change in the career maturity of elementary school students and of attachment to parents and academic achievement as predictors of change. The 2844 participants were 1524 boys and 1320 girls in the Korea Youth Panel Survey. They were fourth graders in 2004 and became seventh graders in 2007. Latent growth curve modeling indicated that : (1) Trajectories of change in career maturity from fourth grade to seventh grade modeled quadratic growth. (2) Variance of career maturity in initial levels, linear slope and quadratic slope indicated individual differences intrajectories of change in career maturity. (3) Attachment to parents influenced initial levels of career maturity academic achievement influenced both initial levels and linear slope of career maturity.

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.

Purpose: The purpose of this research is to develop defense quality evaluation model in order to improve the problem of private sector quality evaluation model and propose the total integrated defense quality management model which enables to evaluate not only large defense industry, but also small-medium industry. Methods: This paper consider the characteristics on ISO 9001 Quality Management System, single PPM, PASS and defense quality and develop defense quality maturity model and index which enables to measure the current quality management level and characteristics and to evaluate operational characteristics in each maturity level for domestic defense industry. Results: From 176 DQMS certified defense industry, the defense quality maturity level is 68,2, C grade. The large defense industry shows, 80.9, A grade; medium industry 69.7, C grade; small-medium industry shows 54.1, D grade. Through the classified types of industries, the current level of quality management of defense industries was diagnosed and the areas to be supplemented for the total quality management were identified. Conclusion: Developed DQMI can be used as the basic information for spreading quality management activities in the defense industry by diagnosing the overall quality management of existing defense industries and quantifying the ambiguity of non-metric measurements and measurement standard that were presented as the threshold of the defense quality management system certification process.

본 연구에서는 전단력과 도체등급 판정항목간 상관관계 분석을 통한 육질평가의 자료로 사용하기 위해 한우암소 200두를 대상으로 하였고, 세부적으로 성숙도와 전단력과의 상관관계를 조사하여 기계적인 연도 측정상에서의 성숙도와 연도간의 상관관계를 분석하고자 실시하였다. 본 연구결과, 육량등급이 낮아질수록 전단력이 낮아져 매우 높은 부(-)의 상관관계가 있는 것으로 나타났으며, 육질등급 항목 중 육질 1차등급과 최종등급은 전단력과 높은 상관관계가 있었으며, 그 중에서도 근내지방도는 매우 높은 상관관계가 있는 것으로 나타났다. 그러나 육색, 지방색, 조직감은 전단력과 직접적인 상관관계가 없는 것으로 나타났다. 한우 암소 성숙도는 육질등급판정에서 하향조정항목으로 설정되어 있으나 도체 성숙도에 따른 전단력의 차이에서는 성숙도 4가 $452.04\;kg/cm^2$로 가장 높은 전단력을 나타낸 반면, 성숙도 5가 $413.11\;kg/cm^2$로 가장 낮은 수치를 나타내었으며, 성숙도 2가 $417.98\;kg/cm^2$이었던데 반하여 성숙도 9는 $428.80\;kg/cm^2$을 나타내어 성숙도와 전단력(기계적 연도측정치)과는 상관관계가 없는 것으로 나타났다. 추가적으로 성숙도와 관련하여 전단력 뿐만 아니라 보수력 및 관능 특성인 다즙성, 향미 등의 종합적인 분석이 가능한 연구조사가 수반된다면 보다 객관적이고 과학적인 육질등급 판정을 위한 자료 확보가 가능할 것이다.

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.

The purpose of this study is to analyze the effects of social support and, career decision-making self-efficacy on career maturity of adolescents of different gender and grades. Further, it aims to provide basic information for career maturity to create career educational program for adolescents. The participants of the study were 447 middle and high school students who were selected from second grade of five schools in Daegu. All participants were tested on social support, career decision-making self-efficacy and career maturity scale. The results were analyzed using two-way ANOVA, Pearson's Correlation Analysis, Regression Analysis with SPSS 18.0. The results of the present research are summarized as follows: first, the results of the ANOVA subscales revealed that there were significant gender and grade main effects and interaction effects of social support, career decision-making self-efficacy and career maturity. Second, the results of the correlation analysis among of the social support, career decision-making self-efficacy and career maturity showed a positive and negative correlation. Third, in terms of the influence of social support, career decision-making self-efficacy had a significant meaningful influence on career maturity. The results of this study can be used as a fundamental reference in career counseling at school for enhancing adolescent's career development and success.

본 연구의 목적은 미용전공대학생의 학년별 진로성숙도와 진로의사결정유형의 차이를 파악하고 진로성숙도와 진로 의사결정유형의 영향을 분석함으로써 미용전공대학생의 진로 상담 및 교육 시 체계적으로 이루어지도록 도움이 될 수 있는 지침개발의 기초자료로 제공하고자 한다. 본 연구의 대상은 수도권 지역의 미용관련학과 336명이다. 진로성숙도는 고학년일수록 높게 나타났으며, 진로성숙도가 높을수록 합리적 진로의사결정유형에, 진로성숙도가 낮을수록 의존적 진로의사결정과 밀접한 상호관련성을 보였다. 고학년일수록 진로 결정을 위해 다양한 정보를 수집하며 체계적인 단계를 거쳐 논리적으로 결정하는 합리적인 유형을 나타냈고. 저학년일수록 자신의 현재 감정이나 상황에 따라 정서적 자각을 통해 결정 내리는 직관적 유형과 주변인이나 환경의 영향에 따라 결정 내리는 의존적인 유형으로 나타났다. 본 연구에서 진로성숙도와 진로의사결정유형은 학년별 차이를 보였으며 또한 두 변인 간의 중요성이 밝혀진 만큼 저학년부터 진로성숙도를 높이고 그에 따라 합리적인 의사결정을 할 수 있도록 학년별 체계적인 프로그램과 함께 진로지도가 이루어진다면 학생들이 진로를 결정하는데 있어 도움이 될 것이라 사료된다.
