  • Purpose: This study is a descriptive survey which attempts to understand family strength, parenting attitude, and the ego-identity perceived by female high school students and identify the factors influencing ego-identity of the students. Methods: Data collection was carried out through a questionnaire survey of 186 female high school students. The collected data were analyzed by descriptive statistics, t-test. ANOVA, correlation analysis, and multi-variate regression analysis while using SPSS 23.0 program. Results: Family strength and the ego-identity perceived by female high school students were at a mid-level, with an average of 207.76 and 149.72 points, respectively. Parenting attitude showed scores higher than the mid-level, recording 90.36 points in average. As a result of analyzing the correlation between the factors, the higher family strength and the ego-identity of female high school students were, the better were the patenting attitudes of perceived parents. Besides, family health, parenting attitude, and family form (nuclear family) were found to be the factors influencing ego-identity formation of female high school students with the explanatory power being 25.5% in total. Conclusion: Developing intervention programs which take into account family strength is considered necessary to help the youth form positive ego- identity.

  • The purpose of this study is to identify the determinants of new venture performance according to years of operation in the view of integrated research framework. We propose the integrated new ventures performance model which is composed of entrepreneur, organization/resources, industrial environment, strategy/foundation process and availability of supporting systems as corresponding variables to new ventures performance. The determinants of new venture performance according to years of operation are identified through the multi-variate statistical analysis such as moderating regression analysis with the data gathered from 110 executives of venture companies. For internal variables, entrepreneur's managerial ability and technical expertise and employee's ability affect venture's performance increasingly as years of operation increases but resource procurement ability affects decreasingly. Related to external variables, years of operation plays positive moderating role on market size growth and supporting system availability, but negative role on government venture policy for venture performances. Though this study has limitation of small sample, limited questionnaire and performance measure, it has managerial contribution of identifying determinants of new venture performance according to years of operation.

  • Recently, there have been many researches to automate processing and analysing image data in medical field, due to the advance of image processing techniques, the fast communication network and high performance hardware. In this paper, we design and implement the system based on the multi-layer neural network model to be able to analyze, differentiate and count blood cells in the peripheral blood image. To do these, we segment red and white-blood cell in blood image acquired from microscope with CCD(Charge-coupled device) camera and then apply the various feature extraction algorithms to classify. In addition to, we reduce multi-variate feature number using PCA(Principle Component Analysis) to construct more efficient classifier. So, in this paper, we are sure that the proposed system can be applied to a pathological guided system.

  • The employment rate has become the standard for university values. This raises the need to investigate the antecedents of university students' career exploration. Focused on the hospitality majored students, this study aims to investigate both individual and relational factors that influence their career exploration behaviors. Differentiation of self has been chosen as the individual and the relational antecedents based on Bowen's theory. It was investigated whether each dimension(I-position, emotional reactivity, fusion with others, and emotional cutoff) explains the amount of self-exploration and the amount of environmental exploration. The university students majoring in hospitality were surveyed and a total of 269 cases out of 300 cases were analyzed employing descriptive statistics and multi-variate analysis of variance, and structural equation modeling(SEM). The study found that I-position positively influenced self-exploration and environmental exploration. Emotional reactivity made an influence on environmental exploration, while it failed to explain self-exploration. Fusion with others and emotional cutoff also significantly influenced environmental exploration, however, it didn't make any significant influence on self-exploration. This study implies that the college of hospitality majors needs to understand that differentiation of self forms through family relationship and needs to provide the students the programs of how to understand themselves and what to do for their career exploration.

  • Purpose:It has been known that the prognosis of a young woman's breast cancer is Poorer than the other woman However, the effect of age on the prognosis is not well-defined We performed this study to investigate age as a prognostic factor of breast cancer. Materials and Methods : A retrospective study was conducted for 3209 breast cancer patients who underwent operations in Department of Surgery, Seoul National University Hospital from January 1981 to December 2000. Patients were divided into two groups, young age(≤35) and old age(>35) groups. And tumor stage, histopathologic characteristics(such as histology, nuclear grade, histologic grade, hormonal receptor, etc), overall survival and disease free survival rates were compared between age groups. Results . The age ranged from 17 to 88 years. 396 patients(12.3%) were included in young age group(median=32) and 2813 Patients(87.7%) in old age group(median=47).There are more advanced stages and poor nuclear grades in young age group(p=0.000, p=0.003), By log-rank test, the young age group had poorer overall survival and disease free survival rates(p<0.05, p=0.0002). Although, the young age group had more advanced TMN stages(p=0.000) and poorer nuclear grade than the old age group(p=0.003) in multi variate analysis, the age was not a significant independent prognostic factor. (P=0.642)Conclusion: Our study showed that the age was not a significant independent prognostic factor.
