The unconfined compressive strength of lightweight treated soils strongly depends on mixing ratio. To characterize the relation between various LTS components and the unconfined compressive strength of LTS, extensive studies have been conducted, proposing normalized factor using regression models based on their experimental results. However, these results obtained from laboratory experiments do not expect consistent prediction accuracy due to complicated relation between materials and mix proportions. In this study, deep neural network model(Deep-LTS), which was based on experimental test results performed on various mixing conditions, was applied to predict the unconfined compressive strength. It was found that the unconfined compressive strength LTS at a given mixing ratio could be resonable estimated using proposed Deep-LTS. 경량혼합토의 일축압축강도는 배합비에 크게 의존한다. 경량혼합토와 다양한 경량혼합토의 구성성분들의 관계를 특징짓기 위한 기존연구에서는 시험을 통한 회귀모델을 사용하여 정규화계수를 제안하였다. 그러나 실내시험에서 얻은 결과는 재료와 배합비사이의 관계가 복잡하기 때문에 일정한 예측의 정확도를 기대할 수 없다. 이 연구에서는 다양한 배합조건에서 수행된 실내시험결과를 바탕으로 심층신경망 모델을 적용함으로써 경량혼합토의 일축압축강도를 예측하였다. 제안된 심층신경망 모델을 사용함으로써 설계 배합조건으로 구성된 경량혼합토의 일축압축강도 값을 합리적으로 산정할 수 있다.

1.Purpose of the study As a study of inquiry about the realites of cowse guidances are forcing in the liberal arts system high school the main purpose of this study is to experiment and to analyze what influence affects the selection of the system of school,as well as school subject by course guidance in time of the liberal arts system high school students who are going to enter the vocational field or continue into college in the future. 2.Method of the study I examined the theoretical background of course guidance through the study of documents and precedent study. The method of carrying out the study<see table 4-1> was the divide the questionnaire into 30questions, 9questions and 9uestions And I studied respectively as to the students consciousness of the course. The as to the parent's view of course the teacher's consciousness of course. The questionnaire about the student's consciousness of cowse was enfarced in advance(106), later(96), and it made parents(41), teacher(44) as on object study and (as in table 4-3) after the first students questionnaire, a second questionnaire was given to see what changes accured through course guidance and consel for the students and their parents. 3.Findings of the study If we examine the results through this experimentation and analysis, The next is : first: The students have formed a distinct self-concept toward their aptitude, capacity, physical peculiarity because they more correctly understood them. Second:The students have a high interest and knowledge of the Vocational world, the present condition of college curriculum and changeable view, they have a confidence in their desired occupation of School Subject, ultimately their attitude toward a vocation is changed affirmativly. Third:In the decision of wheather they go to college or not, when to enter the school propertime, the selection of school system and school subject are decided with wandering and conflict. They decided upon their think correctly and rationally and they propered their future coures with a sense of stability. fourth:Correct and various information concerning the direction of coures quidance was obtained from the questionnaire. it helped to establish future intentional contemplative ability and a distinctive life object. fifth:For teachers cognizance and aptitude about course education was changed affirmatively. The coures education ability has improved. sixth:The parents have had a higher understanding and recognition of the course, it helped them to from the right sense of direction. seventh:The need of documentation for course guidance is recognized in the liberal arts high school. According to the results of this study, I would like to propose the following: first:The course education must be put in force systematically from the elementary school to enlighten and stretched individual qualities, aptitudes second:In the light of the importance for course education if the text book revized so the contents of the course education should be establish in the educational cowse systematically. third:To diffuse and extend course education, we should in stall course education lectures and offer the chance of leadership technic's training to instill an upright understanding of course education. This can be done when training meetings are held for students. fourth:documetation for course education must be developed and earlier developed good documents should be supplied to the schools for the purpose of course education's inner-fertilization schools for the purpose of education's inner-fertilization and qualitative improvement. fifth:We Should consolidate course education public relations at the social and national levels in order to from a beffer sense of value among parents toward vocation and a right understanding about course education. sixth:We should strengthen the chance of study and training for teacher's in order to renew course education and to help them acqire expert knowledge.

비교과프로그램이 대학핵심역량에 미치는 영향 ― K 대학교를 중심으로

박창남,정원희 한국교양교육학회 2017 교양교육연구 Vol.11 No.1

The purpose of this study is to examine how non-subject educational programs affect core competencies based on survey of perceptions and needs on those programs of K University students, and to suggest directions of non-subject education. The non-subject educational programs of K University are classified into 3 domains, which are self-understanding, competency reinforcement, and experience, and experience domain affects the most on developing core competency of K University students. The results and implications of this study are summarized as follows : 1) It is necessary to reexamine the correlation of which non-subject educational program affects on developing specific competency, and restructure existing programs in accordance with the necessity of developing competency of students actually, 2) It is necessary to expand the programs related to related to experience domain which influences academic achievement significantly, 3) It is needed to design student customized programs in order to enhance participation of students and effectiveness of program implementation. Considering above results, the implication of this study is that it shows how universities should establish a variety of student needs-based non-subject educational programs and give a direction how they can lead students to experience different types of such programs and achieve their educational goals. 본 연구는 k 대학의 비교과 프로그램에 대한 학생의 인식조사를 통해 핵심역량에 미치는 영향을 확인하고, 비교과 교육의 방향성을 제고하는데 그 목적이 있다. k 대학의 비교과 프로그램은 자기이해, 역량, 체험 영역으로 구분되며, 실제 분석결과 k 대학 재학생의 핵심역량에 영향을 미치는 비교과 프로그램은 체험 영역이 가장 높게 나타났다. 본 연구의 결과와 그에 따른 시사점을 제시하면 다음과 같다 : 첫째, 실제 설계된 비교과 프로그램이 학생들의 어떠한 역량을 키워주는지 재검토할 필요가 있으며, 학생들의 역량개발에 필요한 프로그램 위주로 기존 프로그램을 재설계할 필요가 있다. 둘째, 체험 영역과 관련된 비교과 프로그램이 역량성취도에 영향을 미치기 때문에 이와 관련된 비교과 프로그램의 확대가 필요하다. 셋째, 비교과 프로그램의 참여 및 효과를 제고하기 위하여 학생수요맞춤형 비교과 프로그램의 설계가 필요하다. 따라서 본 연구의 함의는 대학이 수요자 중심의 체계적인 비교과 교육과정 및 운영체계를 구축하고 학생들의 참여와 프로그램 운영 목적 달성에 중요한 방향성을 제시하는 것이라 하겠다.

청소년의 재학 중 아르바이트경험이 학교부적응에 미치는 영향

박창남,도종수 한국청소년학회 2007 청소년학연구 Vol.14 No.5

본 연구에서는 한국청소년패널조사(KYPS)의 2·3차년도 자료를 활용하여 청소년의 아르바이트경험이 학교부적응에 미치는 효과를 직종과 노동강도의 차원으로 나누어 종적 분석을 시도하였다. 그리고 이러한 효과가 성별, 고교계열별로 어떻게 차이가 있는지도 살펴보았다. 분석결과 청소년의 아르바이트경험은 학교부적응에 유의미한 정적 영향을 미치는 것으로 나타났으며, 이러한 아르바이트경험의 정적 효과는 직종별로 차이가 있는 것으로 나타났다. 학교부적응에 대한 직종 효과의 성별 차이는 미미하였으나, 계열별 차이는 존재하였다. 노동시간은 학교부적응에 정적 영향을 미치는 것으로 나타났으며, 이러한 노동시간의 효과는 성별, 고교계열별로 차이가 있는 것으로 나타났다. 이러한 연구결과를 바탕으로, 청소년에게 교육적 효과를 가져올 수 있는 새로운 직종 개발의 필요성과 청소년들의 장시간 노동을 실효성있게 예방할 수 있는 정책의 필요성을 제기하였다. This study examines the effect of adolescents' part time job experience on school maladjustment, by job type and employment intensity, through a longitudinal analysis using the second and third year data of Korea Youth Panel Survey. In addition, the effect is examined by gender and subject group. The result shows a significant positive effect of part-time job experience on school maladjustment. The effect differs by job type. The effect of job type differs by subject group, whereas no difference is shown by gender. Work hour has a positive effect on school maladjustment. The effect differs by gender and subject group. The result suggests the development of new part-time job to have education effect and the policy to prevent long work hours.
