Recently, new content for e-leisure, including e-sports and e-games, has become necessary. To meet this requirement, e-leisure mobile AR studies which track human are underway. The tracking performance at long distances is important because e-leisure mobile AR is used in outdoor environments. However, conventional mobile AR applications such as SNOW and Snapchat have the disadvantage of low tracking performance at long distances. Therefore, we propose an e-leisure mobile AR in outdoor environments. The proposed e-leisure mobile AR can estimate the position of the head in outdoor environments at long distances by using color markers and the human body ratio, and then augment a virtual object at the estimated position. The performance of the proposed e-leisure mobile AR was evaluated by measuring the tracking performance and processing time.

Accounting is a practical study as a fundamental of a corporate management. In recent years, the necessity of 'Engineering Accounting' and 'Accounting and Society' for non management and accounting major is on the rise. To accelerate the learning effect of accounting, the individual learning and learning by repetition is required. And ERP practice is on the rise as a new trend. The e-learning will be helpful to the individual learning and learning by repetition. The learner study repeatedly and individually by e-learning, and then practice the accounting process by ERP practice. It's also adoptable for Engineering Accounting to use repeated and individual study using e-learning and ERP practice. This paper is focused on the case study of Engineering Accounting using e-learning and ERP practice in Korea University of Technology and Education. To review this case, the development direction of the accounting education and engineering accounting education will be introduced.

The choice of occupation has a great deal of influences on achievement of self-realization and living a good life in an individual's life. Especially, it is very significant for Elementary school students because they become to aware of career and develop. However, in the present, the career guidance is mainly concentrated in the solitary work, such as an aptitude test and printed materials. The perspective from the student, therefore, needs systematic and efficient system to accumulate activities and result of their various career guidance for individual career-related information. The system to improve elementary school student's career awareness based on e-portfolio has been developed. The developed system can effectively accumulate students' activities and result of their various career guidance and easily grasp their strengths and weaknesses of intelligence based on theory of multiple intelligences. Teacher also can easily grasp their student's talent through all sorts of graphs provided by the web site for career education.

Objective: This study aims to analyze parents' perception of the suitability of the 'Childcare Support Center (C.S.C.)' and the 'Early Childhood Education Promotion Institute(E.C.E.P.I)' as home care support service providers. Methods: The goals and content of the home parenting support service offered by the C.S.C. and E.C.E.P.I. were analyzes based on information collected from their websites, publications, and various promotional materials. There were categories into 18 services across 5 categories. Responses of 421 parents, gathered through a questionnaire developed with reference to previous studies, were collected and analyzed. Results: Parents reported high degree of suitability for the organizations they used. Those familiar with both institutions found E.C.E.P.I. more suitable overall. However the C.S.C. was considered particularity suitable by parents of children aged 0-2 years and by those with no prior experience with either institution. The perceived suitability of the two institutions varied by service, depending on factors such as the age group of the children, whether the parents lived in the metropolitan area, and whether they were part of a double-income household. Conclusion/Implications: These findings have practical implications for development of integrated policies for early childhood education and childcare, which should take into account parents' perceptions of the functions of institutions.

Objective: E-cadherin has been identified as a tumor suppressor in many types of carcinoma. However, some studies recently suggested that the role and expression of E-cadherin might be more complex and diverse. In the present study, we evaluated the prognostic value of E-cadherin expression with reference to levels in membranes and cytoplasm, and the membrane/cytoplasm ratio, in hepatocellular carcinomas (HCCs) after curative hepatectomy. Methods: The expression of E-cadherin was assessed by immunohistochemistry in HCC tissue microarrays from 125 patients, and its prognostic values and other clinicopathlogical data were retrospectively analyzed. Patients were followed for a median period of 43.7 months (range 1 to 126 months). Results: Univariate analysis demonstrated that a high membrane/cytoplasm (M/C) ratio of E-cadherin expression was associated with poor overall survival (OS) (P =0.001) and shorter time to recurrence (TTR) (P=0.038), as well as tumor size, intrahepatic metastasis, and TNM stage. In contrast, neither membrane nor cytoplasmic expression of E-cadherin was related with OS and TTR. Furthermore, multivariate analysis confirmed the M/C ratio to be an independent predictor of OS (P=0.031). ${\chi}^2$ tests additionally showed that the M/C ratio of E-cadherin expression was related with early stage recurrence (P=0.012), rather than later stage recurrence. Conclusion: The M/C ratio of E-cadherin expression is a strong predictor of postoperative survival and is associated with early stage recurrence in patients with HCC.

The purpose of this study was to compare and analyze the finger pressure and kinematic variables in the forehand hairpin net shot between skilled elite players and less skilled recreational players. Eight elite players(age: $18.1{\pm}0.8yrs$, height: $176.8{\pm}1.5cm$, weight: $640.9{\pm}48.6N$) with minimum of 6 years of experience and eight recreational players(age: $27.9{\pm}1.6yrs$, height: $177.1{\pm}6.1cm$, weight: $820.5{\pm}62.8N$) with less than one year experience were recruited in this study. For each trial being analyzed, four critical instants were identified from the video recordings: Right heel contact1 (E1), Right toe-off (E2), Right heel contact2 (E3), and Shuttlecock Impact (E4). Each hairpin net shot was broken into consecutive phases: E1~E2 (Right Landing Phase: RLP), E2~E3 (Sliding Step Phase: SSP), and E3~E4 (Impact Phase: IP). Temporal parameters, shuttlecock speed, linear and angular kinematics of body segments, and finger pressures were computed for this study. The results showed that The finger pressure of the ring finger and the middle finger for the skilled group during an impact had significantly greater than those of unskilled group. It is possible that all fingers were not used in the same manner when the racket was gripped in forehand hairpin. The result also suggested that the ring finger and the middle finger pushed the racket from top to bottom while having the mid-phalanx and proximal phalanx of index finger as an axis.

As basic data about students' career education in high school are being managed only in forms of NEIS, which is supported by Ministry of Education, Science and Technology, and the information for career education that homeroom teachers have operated by off-line system, it is hard to use them as practical decision support system for students' career education. In this study, we intend to design and embody web-based Student Management Total System by constructing DB of students' e-portfolios, school records and counselling data etc. As a result, teachers can carry out vocational education that is considered students' talents and aptitude, and we have a goal for promoting the growth of the students as the national human resources who have sound occupational consciousness through this education.
