This research aims to develope a maturity evaluation model on the technology management competence (MEMTMC) and to investigate the relationship between technology management competencies and maturity evaluation level in Korean firms. After research framework building through literature review and field study focusing on interview process, a maturity evaluation model was suggested, including technology management competency factors such as vision and strategy, leadership, resources, projects, performance management, and systematic procedures. Through the empirical study on the 111 Korean firms, the MEMTMC model was tested and some hypotheses were examined. As a result of the research, we found that the MEMTMC is significant statistically to evaluate the technology management competencies of firms from a practical point of view. Additionally, these findings suggest that firms can build up their technology management competencies, including the vision and strategy, leadership, resources, projects, performance management, and systematic procedures in order to raise their maturity level of technology management competencies. But this research has some limitations such as this MEMTMC has not considered separately the variety of industry, not enough survey respondents and 5 level group firms etc.

In this study, tomato maturity was estimated based on deep learning for a harvesting robot. Tomato images were obtained using a RGB camera installed on a monitoring robot, which was developed previously, and the samples were cropped to 128 × 128 size images to generate a dataset for training the classification model. The classification model was constructed based on convolutional neural networks, and the mean-variance loss was used to learn implicitly the distribution of the data features by class. In the test stage, the tomato maturity was estimated as a continuous index, which has a range of 0 to 1, by calculating the expected class value. The results show that the F1-score of the classification was approximately 0.94, and the performance was similar to that of a deep learning-based classification task in the agriculture field. In addition, it was possible to estimate the distribution in each maturity stage. From the results, it was found that our approach can not only classify the discrete maturation stages of the tomatoes but also can estimate the continuous maturity.

Purpose: The purpose of this study was to figure out the association of nursing activity participation and clinical practice stress with career maturity during clinical practice among nursing college students. Methods: Participants of the study were 201 nursing college students located in nationwide regions. Data collection was performed between July 18 and August 8, 2019. Data analyses were performed through an independent t-test, ANOVA, Pearson's correlation coefficient, and multiple linear regression analysis using SPSS WIN 25.0. Results: The results of this study were as follows. We ran multiple regression analyses to see which critical factors influenced career maturity. The general characteristics significantly associated with career maturity were preference for clinical nursing, admission to nursing college due to belief, time off, and being satisfied with clinical practice. Regarding clinical practice stress, clinic environment, interpersonal relationship conflict, inappropriate role model and conflict with patients were significantly associated with career maturity. Conclusion: This study suggested that, to improve nursing students' career maturity, nursing colleges and training fields should collaboratively make an efforts to reduce students' stress by building educational clinic environments including managing conflicts in interpersonal relationships among patients, caregivers, and medical and non-medical personnel, and improving inappropriate role models in nursing.

Little is known of the life history of Garcinia kola; the objective of this study, therefore, was to assess the fruiting age and tree size of the species in a coastal humid tropical climate plantation condition. A total 103 trees were used in the study viz; 80 ten-year-old trees at reproductive maturity onset and 13 thirty-year-old trees with several cycles of reproduction that constitute two independent variables. Data collected were age of onset of flowering and size at reproductive maturity onset. Relative size at reproductive maturity onset (RSOM) was estimated as size at reproductive maturity onset (SOM) divided by asymptotic maximal size (AMS). Data analysis was conducted using pairwise t-test and principal component analysis (PCA). Reproductive maturity onset (flowering) was recorded in the ten-year-old stand eight (8) years after planting. Mean size at reproductive maturity onset (SOM) was height 5.32±1.7 m, dbh 0.11±0.03 m, total number of branches was 29.6±7.3, crown depth 5.24±1.05 m, crown diameter was 4.78±0.7 m, branch diameter 0.098±0.01 m, leaf length 0.13±0.02 m, leaf breadth 0.37±0.01 m, twig length 0.35±0.11 m and leaf per twig 6±0.84 and asymptotic maximal size (AMS) was height 19.85±0.76 m, dbh 0.95±0.09 m, total number of branches 62±5, crown depth 18.83±0.7 m, crown diameter 12.5±1.64 m, branch diameter 0.5±1.6 m, leaf length 0.16±0.023 m, leaf breadth 0.45±0.12 m, twig length 0.37±0.11 m and leaf per twig 19±7.5. Pairwise t-test analysis showed there was significant differences between SOM and AMS in all growth factors except leaf length, leaf breadth, and twig length. Highest relative size at reproductive maturity onset (RSOM) was recorded in leaf length 0.82, twig length 0.82, and leaf breadth 0.80, while, the lowest was branch diameter 0.11. Four components out of the total of eleven were extracted to explain the relationship in RSOM: Principal component one (PC1) explained 37.23%; PC2 26.4%, PC3 22.73%, and PC4 13.64%.

The purpose of this study was to identify the influences of psychological independence(functional independence and emotional independence) and career decision-making self-efficacy(self-estimation, career goal, occupational-knowledge, and problem solving) on career maturity(preparation, objective, decisiveness, and certainty) among adolescents. The subjects were 447 students in the second grade of middle school and high school in D. The questionnaire consist of measures of psychological independence, career decision-making self-efficacy, and career maturity. The data were analysed with factor analysis, Cronbach's ${\alpha}$, t-test, ANOVA, correlation and multiple regression by using the SPSS(SPSS/WIN 19.0) program. The major results were as follows. First, adolescents' the career maturity was significantly different depending on the socio-demographic variables. Second, it was shown that middle and high school students have a statically relation, in a relation among psychological independence, career decision-making self-efficacy, and career maturity. Third, it was found that psychological independence and career decision-making self-efficacy gave statistically meaningful influence on the career maturity of adolescents. This study is significant in that it suggests a plan for improving career maturity, and provides a basic material to improve one's active role in their parents.
