대부분의 빈발 부분그래프를 이용한 그래프 분류 알고리즘들은 빈발 부분그래프를 마이닝하여 개별적인 빈발 부분그래프의 포함 여부를 특징 벡터로 구성하는 단계와 기계학습 알고리즘들을 훈련시켜 분류 모델을 수립하는 단계로 구성된다. 이와 같은 그래프 분류 알고리즘들은 부분그래프의 개별적인 존재 여부만을 이용하여 특징을 구성하기 때문에 변별력이 떨어지는 문제점이 있다. 본 논문에서는 빈발 부분그래프들이 동시 발생하는 특징 벡터의 변별력을 반영할 수 있는 특징선택 기법을 적용한 모델 기반 탐색트리 기법을 제안한다. 동시 발생 부분그래프를 특징으로 사용하여 변별력을 향상시킬 수 있으며, 모델기반 탐색 트리를 사용하여 제안하는 기법이 기존의 방법보다 더 높은 그래프 분류 성능을 보이는 것을 입증하였다.

Background: The purpose of this study is to evaluate the effects of the Motivational Interviewing (MI) based communication training for third-year nursing students. Methods: This study use a quasi-experimental design with pre and post-test to evaluate a 4-hour MI based communication training. This training was offered to 35 third-year nursing students who were participating in elective psychiatric nursing clerkship course. Each student completed pre and post questionnaire which includes assessment of motivational interviewing skills as measured by Helpful Response Questionnaire (HRQ). Also confidence (5 items) in using MI based communication knowledge and core skills were included. Data were independently analyzed by two coders and blindly rated the pre and post HRQ self-reported responses. Data were analyzed using paired t-test, descriptive analysis. Results: Nursing students showed increasing use of reflection (4.10~5.67, p<.001), decreasing use of closed-ended question (2.00~0.73, p<.001), road blocks (2.94~0.64, p<.001), and improve in depth of reflection (12.79~20.86 p<.001). But they did not show significant changes in open-ended question (2.01~2.33, p=.257). Confidence in the interview has increased overall, except for reflecting. The overall satisfaction with the training was quite high, and the most helpful training method was group and individual feedback. Conclusions: This study provides evidences that 4 hour-training is effective in core skills such as reflection and depth of reflection, and also confidence in interviews. It is necessary to develop step-by-step training modules to enhance undergraduate communication skills. It is necessary to develop an effective training strategy focused on students' confidence in open-ended questions and reflection.

Computer based teaming system has considerable influence upon teaching technique and teaming efficiency. It is possible to make a learner-oriented teaching in the online learning system. In this case, it can provide easily and immediately learner with various information that relate to class status, for example, attendance, examination score and so on. In the case of conventional off-line education, however, it is inefficient to provide the information of class status for learners compared with on-line system. In this paper, we propose a monitoring system of class status which can provide various information of teaming status for learners, instructors and advisors. It is useful to advise student's course work and job. The main purpose of this system is to prepare a monitoring system of class status on a web based e-class system. It achieves self-monitoring systems which provide a feedback data as a result of class for students.

This study was to investigate the influence of using Therapeutic Instrumental Music Performance (TIMP) in uninvolved hand function for children with spastic cerebral palsy. Participants were recruited from a welfare center for people with cerebral palsy(CP). Ages ranged from 11 to 12, and a total of 15 TIMP sessions were provided for 3 weeks. Hand function tests were used including Jebsen Hand Function Test for hand function, Box and Block Test for dexterity of uninvolved hand, and MIDI (Musical Instrument Digital Interface) evaluation for velocity of fingers. The TIMP program consisted of hand percussion playing and keyboard playing with changes of timbre and tempo. While the scores of Jebsen test and Box and Block test were improved for all participants, outcomes of MIDI analysis showed differences among participants. Overall, hand function improvements were observed after the completion of using the TIMP program, and the results implies that the TIMP program can be applied in upper extremity rehabilitation for children with CP.

The development of information technologies has contributed on-line training as one of important education methods. On-line training in firms, which is similar to e-learning or virtual education, provides trainees with more education opportunities in diverse ways. It has developed a range of innovative services with a one-stop solution of education within the electronic sector. Also under the on-line training environment, trainees can undertake customized training packages at anytime and any places. Moreover, information technology allows both the trainers and other trainees to be decoupled in any of the elements of tune, place, and space. Two research questions are investigated : what are the determinants affecting the on-line training effectiveness and how those variables affect the two aspects of training effectiveness: learning performance and transfer performance. Based on the previous literature conducted on the traditional training environment, the determinants of training effectiveness are derived. Eight hypotheses are developed based on literature reviews and tested by questionnaires survey data. The collected data have been analyzed by LISREL. It is found that the relationship between individual, organizational and on-line site design variables and training effectiveness (learning and transfer) are significant. The contribution and limitations of this research are also discussed with future studies.

Objective : The purpose of this study is investigate the effects of sensory integration combined with auditory treatment on the sensory processing, visual perception and attention ability of children with developmental delay. Methods : A combined treatment of auditory training and sensory integration therapy was implemented to 3 children aged 4 to 7 and diagnosed with developmental delay during 9 weeks period from December 2016 to January 2017. ABA' design which is one of single subject research designs was used in this study. Baseline A had 4 sessions, intervention B had 15 sessions, and baseline A' had 4 sessions, so 23 sessions were applied in total. During the baseline A and A 'periods, visual perception ability was measured by K-DTVP-2 (Korea Developmental Test Visual Perception-2) and sensory processing ability was evaluated by sensory profile. The maintenance time of attention was measured with the absence of intervention for the baseline period, and for the intervention period, it was measured at 10 minutes break time which was provided after the intervention. The children's attention time during a fine motor task provided were measured using video recorder with the interval recording method, and the interval for the evaluation was 30 seconds. Results : No statistically significant difference were found in the visual perception function and sensory processing scores before and after treatment. Attention of participant A enhanced significantly while that of participant B and C did not improve significantly. Conclusion : It is hard to conclude that sensory integration therapy combined with auditory perception training has positive effects on visual perception function and attention of children with developmental delays. However, there were significant increase in attention and improvements in behavior related to sensory processing for some cases in this study. In further study, longer intervention periods and valid measurement need to be applied in order to get better results. And it is proposed that more studies need to be done to enhance evidence of auditory perception training as a mean to facilitate attention and to prepare learning.
