기존의 VOB(Virtual Output Buffer) 모델에서 신경회로망의 학습 패턴 처리를 위해 가상 셀 손실율이 도입되었다. VOB모델은 신경망이 실제 셀 손실율 없이도 연결 수락 경계을 잘 찾을 수 있음을 보여주었다. 그러나 VOB 모델은 셀 손실율을 과다 평가하는 경향이 있어 결과적으로 망 자원의 이용률이 낮은 단점이 있다. 본 논문에서는 이러한 단점을 보완하는 방법으로 연결 수락 경계에서 셀 손실율의 평균에 대한 정보를 충분히 포함하는 셀 손실율 참조 곡선의 개념을 제안하였다. 그리고 제안된 셀 손실율 참조 곡선을 이용하여 가상 셀 손실율을 처리하는 방법을 제안하였다. 제안된 한습 패턴 처리 방법은 ATM 트래픽 중에 가장 대표적인 두 가지 호원에 대하여 실험하였다. 실험에 사용된 호원은 LAN 데이터의 그래픽 특성을 가시는 On-Off 트래픽과 비디오 화상 통신의 특성을 가지는 Auto-Regressive 트래픽이다.

This study surveyed 255 college students enrolled in beauty contract departments located in Seoul(5 schools) and Gyeonggido(6 schools) to investigate their admission support procedure and educational satisfaction. The study found as follows; Data collection was performed from March 25 to May 30, 2018 using SPSS WIN 21.0 for their statistical processing. With respect to data analysis, first, frequency analysis was conducted to look at the general characteristics of the subjects. Second, the admission support procedure of beauty contract department was investigated and cross analysis was performed to see if there was any change according to the subjects' general characteristics. As a result of looking at the awareness on department, 89% were found to be aware of the contract department system. As for their motivation to applying for the department, the largest reasons were found to obtain a degree and to become a hair designer within a short period of time. The most frequent route of application was a recommendation by their high school teachers. The highest priority consideration in choosing a department was the brand awareness of an associated industrial entity. With respect to the complementation education in curriculum, practical technique related to the major was found the highest. 66.7% said they would recommend the department when it comes to the intention to recommend the department. 24.0% were found satisfied with the education regarding educational satisfaction. Therefore, in order to improve the educational satisfaction of the contract department, it is necessary to acquire knowledge of the field technique and practical salon education.

Although current wireless mesh network (WMN) applications experience a perceptually uninterrupted hand-off, their throughput after the hand-off event may be significantly degraded due to the low available bandwidth of the mobile client's new master. In this paper, we propose a novel mobility management scheme for 802.11-based WMNs that enables both seamless hand-off for transparent communications, and bandwidth awareness for stable application performance after the hand-off process. To facilitate this, we (i) present a new buffer moment in support of the fast Layer-2 hand-off mechanism to cut the packet loss incurred in the hand-off process to zero and (ii) design a dynamic admission control to grant joining accepts to mesh clients. We evaluate the benefits and drawbacks of the proposal for both UDP and TCP traffic, as well as the fairness of the proposal. Our results show that the new scheme can not only minimize hand-off latency, but also maintain the current application rates of roaming users by choosing an appropriate new master for joining.

Multiple cohorts (e.g., current students and graduates) were formed to collect information on the entire educational process from admission to graduation regarding students' educational performances at Kosin University College of Medicine. Data that had already been collected and analyzed by different committees for different purposes were grouped into a more systematic and comprehensive system called the cohort system, enabling the necessary data to be collected promptly and analyzed in accordance with the purpose of providing meaningful information in each area of the educational process. Therefore, comprehensive cohort data that can be used for mission statement revision, curriculum development and improvement, student counseling, and student selection were established and utilized. The cohort data were collected from performance evaluation indicators including self-evaluation surveys, evaluation tools for learning outcomes, academic achievement, results of the Korean Medical Licensing Examination, and career placement. Based on the results obtained by analyzing cohort data, a comprehensive cohort report has been published. The data analyzed through the cohort were reported to each committee and used in various ways. Currently, however, only some data have been analyzed and used. In the future, after complete data collection, the cohort data can be used as meaningful basic data for achieving the institution's mission and educational goals, developing and improving the curriculum, counseling students, and selecting students through the analysis of learning performance data from student admission to graduation and after graduation.

본 연구는 대학에서 학생들에게 입학과 함께 전문지식과 덕성을 갖출 수 있도록 관리 지원하는 프로그램(K-Leader마일리지)을 통해 대학생의 핵심역량 데이터를 입학전형 유형별로 나누어 그 차이를 비교 분석하였다. 분석결과는 리더십과 인간관계 영역을 제외하고 나머지 영역은 상대적으로 활동인원이 많이 부족한 것으로 나타났다. 리더십과 인간관계는 수능위주(수능) > 학생부위주(교과), 학생부위주(종합) 학생부위주(교과) 수능위주(수능) > 수능위주(수능+학생부), 글로벌 영역은 수능위주(수능+학생부) 수능위주(수능) > 학생부위주(종합), 수능위주(수능+학생부) 수능위주(수능) > 학생부위주(교과), 진로 및 취업활동은 학생부위주(종합) 학생부위주(교과) > 수능위주(수능+학생부), 마일리지점수 합계는 수능위주(수능) > 학생부위주(교과) 수능위주(수능)의 결과로 나타났다. 이러한 결과로 볼 때, 리더십과 인간관계의 항목인 공동체 참여의 활동만으로 보면 기존 연구와 같이 학생부위주(종합)전형의 학생이 학교생활을 잘한다는 연구 결과와 같다. 그러나 본 논문에서의 K-Leader 마일리지 분석결과는 수능위주(수능)전형이 대학생활을 잘 한다는 결과를 얻을 수 있었다.

Four design candidates for a partial admission turbine have been chosen from a preliminary design process. Their performance were estimated through the 3-D numerical analyses using a frozen rotor method. In order to select the optimum design, each flow analysis result was compared with others. Flow characteristics in the passages and some types of losses induced by shocks and wakes were found from calculation results. Based on these calculations, a new rotor blade was redesigned and compared with previous one through flow analysis.

This study aims at solving the problem in the application method of the comparative school record which is currently being discussed in depth among colleges. The application method of Kay O. Lee and Yeon Soo Cung(1997) which was appied in the 1999 Korean air force Academy Admission Process was found to be problematic in the following respects. First the setting of the standard which divides all the high schools in kora into five groups relative to their scholastic level is somewhat vague and subjective secondly the difference among those levels which resulted from the five grouping could greatly influence on the admission of the applicants and thirdly there is no standard in choosing those few promising individuals with high scholastic aptitude test results from the low level groups such as level four and five,. Therefore this study suggests and introduces a nationwide individual scholastic evaluation that would complement the limits and problems in the application method of the comparative school record.
