The purpose of this study was to provide effective career coaching method to help university students to choose suitable career in transition to society. The subjects were 250 students enrolled in G University and questionnaire survey was administerd. The collected data were analyzed using SPSS v. 21.0 statistics package program and the results are as follows: For the general characteristics of subjects, female students were more compared to male ones, mos of them were in 4th grade and specialized in public health and had no religion. For the relationship between self-management / self-resiliency and career maturity of university students, the self-management had significant positive effects on determination, confidence, and preparedness, which are sub-factors of career maturity (p<.001). In addition, it was shown that the controllability, positiveness, and sociability, which are sub-factors of self-resiliency had significant positive effects on determination, confidence, and preparedness, which are sub-factors of career maturity (p<.05, p<.01, p<.001). Considering that the self-management and self-resiliency are important factors in career maturity of university students, it is demanded for the university teachers to examine the measures to increase self-management and self-resiliency of students.

The purpose of this study was to evaluate the effects of growth factors such as epidermal growth factor (EGF) and insulin-like growth factor-1 (IGF-1) on maturation of bovine follicular oocytes in vitro. Oocytes were recovered from the ovaries of slaughtered Hanwoos. The oocytes were matured in TCM 199 at 39$^{\circ}C$, 5% $CO_2$ in air. Growth factors were added to maturation medium as follows: control (no serum), EGF (10ng/m1, 50ng/ml or 100ng/m1), IGF-1 (100ng/m1) and EGF (50ng/ml) + IGF-1 (100ng/m1). The oocytes were placed onto a slide and stained with aceto-orcein dye. Nuclear maturation was evaluated and classified as germinal vesicle breakdown (GVBD), metaphase-I (MI) or metaphase-ll(Mll). Maturation rates were 37.9% (control), 45.8% (EGF, 10ng/m1), 55.8% (EGF, 50ng/ml), 44.4% (EGF, 100ng/m1), 46.7% (IGF-1, 100ng/m1) and 67.0% (IGF-1+EGF). The highest group developed to Mll stage was IGF-1+EGF treatment group (p<0.05). Therefore, nuclear maturation of bovine oocytes were affected by both of growth factors, and it seems to have a mutual activity between them.

This study was determined to change in chemical composition of Mume(Prunus mume Sieb. et Zucc) fruits during maturation. There were no differences in the soluble solid and moisture content among varieties, but the soluble solid slowly increased with maturing. The pH and ash content were slightly decreased with maturation. The green color of 'Nanko' fruits was maintained for 92days after full bloom at the greeness value of -3.81 Whereas, the chlorophyll content of 'Koume' fruits remarkably decreased and it was not suitable for the processing of immature green Mume fruits. The titratable acidity increased during maturation. The organic acids were mainly composed of malic acid and citric acid. The malic acid was significantly decreased during maturation, whereas citric acid increased. Major free sugars and sugar alcohols were sucrose, glucose, fructose, sorbitol and maltose. Sucrose content increased as the maturity proceeded, whereas glucose and sorbitol were decreased. The total contesnt of free amino acids decreased with maturation and the total free amino acids in the flesh of fruits were occupied by asparagine at the range of 60 to 78%.

The purpose of this research is to examine the relationships among data literacy, organizational culture, and data analytics maturity and the moderating effects of organizational culture. Analysis of the relationship between data literacy and data analytics maturity shows that the higher the data literacy competency of employees, the higher the organization's data analytics maturity. In examining the relationship between organizational culture and data analytics maturity, it is found that relationship culture and innovation culture are positively related to data analytics maturity. In addition, relationship culture and hierarchy culture show significant moderating effects. Relationship culture shows a synergistic effect, whereas hierarchy culture has a buffer effect between data literacy and data analytics maturity.

In the rapidly developing information technology environment, information management organizations need to effectively evaluate their digital maturity and clarify the direction of improvement to effectively respond to rapidly changing environments. This study derived weights for the digital curation maturity model developed by KISTI from the perspective of digital transformation to facilitate effective evaluation and direction setting of information management organizations. Relative importance was derived as a weight in the major and middle categories of the model through the AHP technique. Summarizing the results, when the major categories of the entire model are measured on the basis of 100 points, technology is 27 points, data is 24 points, strategy is 19 points, organization (manpower) is 16 points, and (social) influence is calculated as 14 points. In addition, weights for each subcategory were presented for each major classification based on a perfect score of 100 points. It is expected that a more objective and reasonable evaluation will be possible by applying the weights for each area derived from this study to the digital transformation maturity evaluation model.

The evaluation of growth potency can be done with many physiologic indicators. It has been well known that skeletal maturity has a close relation with both sexual maturity and somatic maturity, but the correlation between skeletal maturity and dental maturity was believed to be less certain. But, recent studies show that specific teeth, including lower canines, present close correlations with skeletal maturity. So, in this study, we studied hand-wrist X-ray films and orthopantomograms of 387 Korean boys and girls aged from 7 to 15; the purpose was to determine skeletal and dental maturity, and to find out a new method to estimate individual skeletal maturity using multiple-regression model, without the help of hand-wrist X-ray film. As a result of this study, followings were observed. 1. The following multiple-regression model can estimate skeletal maturity index (SMI) with 84% of accuracy, and regression coefficient of chronologic age, sex and lower canine show statistical significance. SMI = 0.60 x chronologic age - 1.67 x sex$^{**}$ + 0.88 x lower canine$^{*}$ - 0.05 x lower 2nd molar$^{*}$ - 10.3 $^{*}$ : mean age corresponding each developing stage, $^{**}$ : male=1, femal=0 2. The following multiple-regression model can estimate skeletal age with 87% of accuracy, and regression coefficient of chronologic age, sex and lower canine show statistical significance. Skeletal age = 0.75 x chronologic age - 0.55 x sex$^{**}$ + 0.71 x lower canine$^{*}$ - 0.09 x lower 2nd molar* -5.77 $^{*}$ : mean age corresponding each developing stage, $^{**}$ : male=1, femal=0

The observation using an electron microscope shows that the maturation of the oocyte of African giant snail, Achatina fulica, proceeds over three stages. The oocyte of stage 1 is a small elliptic cell $(220\times400{\mu}m)$ whose light nucleoplasm contains two nucleoli. In its cytoplasm, a number of mitochondria, rough endoplasmic reticula, and ribosomes are found, while yolk granules are not. The nucleus of the oocyte of stage 2 is relatively large in comparison with the volume of cytoplasm, and contains one nucleolus. In the nuclear envelope comprising inner and outer double membrane, there are found a lot of nuclear pores for materials to pass through. A number of mitochondria, Golgi complex and lipid yolk granules appears in the cytoplasm, and proteinous yolk granules begin to form and mature in the vacuoles of various sizes ($0.8\sim3.0{\mu}m$ in diameter). The oocyte of stage 3 has an enlarged nucleolus. Material transportation through nuclear pore is not found any longer. The cytoplasm in this stage is filled with proteinous and lipid yolk granules. The microvilli are developed around the egg plasma membrane.

The purpose of this research is to propose a practical guideline for activating EA which has been operated in the public institutions. For this purpose, how EA is being operated in the public sector, was analyzed from the viewpoint of IT Governance and on the basis of the result, key activities for EA managers could be developed. The key activities were also compared between the two different groups in terms of EA Maturity Level and the difference in the key activities between the two were examined. As a result, it was found that the use of EA has effect on building and improving IT management systems. It is suggested that the Relational Mechanism should be better understood and recognized as necessary activities for activating EA. In addition, the higher the level of EA maturity is, the more likely such various effects as the enhancement of IT management system, user satisfaction, IT utilization, and the improvement of business can be produced. This result could be interpreted that such desired outcomes of EA could be realized only when EA is actively utilized.
