예체능계 특수목적고등학교 학생의 학교생활 및 진로 만족도에 영향을 주는 변인 분석

김석동(Seok Dong Kim),박재정(Jae Jeong Park) 학습자중심교과교육학회 2021 학습자중심교과교육연구 Vol.21 No.9

목적 이 연구의 목적은 특수목적고등학교(예체능 계열) 학생들의 학교생활 및 진로 만족도에 영향을 미치는 변인을 알아보고 영향력을 검증하는 과정을 통해 조기에 진로를 결정하고 유지한 학생에게 영향을 주는 변인을 확인하는 것이다. 방법 이를 위해서 2019년도 초중등 진로교육 현황조사 자료를 활용하여 예체능계열 특수목적고등학교 학생들을 대상으로 변인들을 추출하여 회귀분석하였다. 이 연구의 주요 결과는 다음과 같다. 첫째, 다중회귀분석을 통해 개인적 변인이 학교생활 및 진로 만족도에 미치는 영향을 추정하였다. 결과 개인적 변인인 도전정신(β=.367, p<.000), 학습태도(β=.189), 학습동기(β=.043) 순으로 학생의 만족도에 영향을 주는 것을 확인할 수 있었다. 둘째, 다중회귀분석을 통해 환경적 변인이 학교생활 및 진로 만족도에 미치는 영향을 추정한 결과 가정적 요인이 학생의 만족도에 영향을 주는 것을 확인할 수 있었다(β=.158, p<.001). 셋째, 다중회귀분석을 통해 진로 인식 및 진로 활동 인지가 학교생활 및 진로 만족도에 미치는 영향을 추정한 결과 진로 인식(β=.512, p<.000)은 학생의 만족도에 영향을 주는 것을 확인할 수 있었지만, 진로 활동 인지는 학생의 만족도에 유의미한 영향을 주지 않았다. 결론 이 연구결과에서의 유의미한 변인을 활용하면 예술계 특수목적고등학교 학생들처럼 조기에 진로를 선택하고 유지하는 학생들을 위한 맞춤형 진로프로그램 개발에 중요한 단서가 될 것으로 기대한다. Objectives The purpose of this study was to find out the variables that affect the school life and career satisfaction of students of special purpose high school (art and physical education) students and to identify the variables that affect the students who decided and maintained their career early through the process of verifying their influence. Methods To this end, using the data from the 2019 elementary and middle school career education survey, variables were extracted and regression analyzed targeting students of physical education and art high schools among special-purpose high schools. The main results of this study are summarized as follows. First, as a result of estimating the effect of individual variables on school life and career satisfaction through multiple regression analysis Results Individual variables, in order, such as challenge spirit (β=.367, p<.000), learning attitude (β=.189), and learning motivation (β=.043), was confirmed to affect the satisfaction of students. Second, as a result of estimating the effect of environmental variables on school life and career satisfaction through multiple regression analysis, it was confirmed that the hypothetical factor influenced student satisfaction (β=.158, p<.001). Third, as a result of estimating the effect of career recognition and career activity recognition on school life and career satisfaction through multiple regression analysis, it can be confirmed that career recognition (β=.512, p<.000) affects student satisfaction. Conclusions There was, however, recognition that career activity did not significantly affect student satisfaction. The use of meaningful variables is expected to be an important clue in the development of career programs for students who choose and maintain careers early, as well as students of special purpose high schools in the arts.

한국형 발전국가에서 사회적 다원화와 불평등에 따른 합의 민주주의의 요구 세계화와 외환위기 및 코로나19 이후에 ‘민주주의의 질’ 성찰

김석동(Kim, Seok-Dong) 서강대학교 현대정치연구소 2021 현대정치연구 Vol.14 No.1

민족적 동질성과 사회경제적 평등은 다수결 민주주의가 형성되는데 우호적인 조건이다. 반면 사회적 다원화와 불평등이 증가하게 되면 다수결 민주주의보다는 합의 민주주의가 대표성을 향상하여 민주주의의 질을 더 효과적으로 개선할 수 있다. 한국사회가 세계화와 외환위기 이후에 사회적 다원화와 사회경제적 불평등을 경험하면서, 경제민주화를 반영할 수 있는 합의 민주주의로 정치개혁의 요구가 거세지고 있다. 세계화 이후에 한국은 민족적 동질성의 약화와 함께 외국인과 탈북자 유입의 증가로 인해 사회적 다원화의 경향이 점차 강해지고 있다. 아울러 한국은 국가건설 초기에 평등한 사회였으나, 1997년 외환위기 이후의 저성장 시대에 특히 2020년 이후의 코로나19 대유행의 국면에 사회경제적 차원에서 불평등한 사회로 전환되고 있다. 게다가 한국의 급속한 산업화 과정에서 서울과 수도권 중심의 경제발전으로 인해 중앙과 지방 간의 양극화가 심해지고 있다. 이와 같은 사회경제적 불평등은 선거에서 현저한 쟁점으로 부상해왔으며, 반(半)다원적 사회로의 전환은 잠재적 쟁점이다. 이에 따라 한국 정당과 시민사회는 보편적 복지국가와 경제민주화 의제를 개헌 등의 담론을 통해 제기해왔다. Ethnic homogeneity and socioeconomic equality are conditions favorable for the formation of majoritarian democracy. Meanwhile, as social pluralization and inequality increase, consensus democracy can enhance the quality of democracy more effectively through enhancing representation than majoritarian democracy. As Korean society experiences social pluralization and socioeconomic inequality after globalization and the financial crisis, there is an increasing demand of political reforms for consensus democracy that reflects multiculturalism and economic democratization. Since globalization, South Korea has become increasingly more plural due to the weakening of ethnic homogeneity, as well as the increasing influx of ethnic minorities, foreigners, and North Korean defectors. Furthermore, during state building, South Korea was an egalitarian society, but is rapidly transforming into an unequal society in the socioeconomic dimension during the era of low economic growth after the financial crisis, particularly in the post-2020 COVID-19 pandemic. Moreover, during Korea’s rapid industrialization period, polarization between center and periphery has intensified due to economic development centered on Seoul and the metropolitan area. This socioeconomic inequality has emerged as a salient issue in elections, and the transition to a semi-plural society is a potential issue. Accordingly, Korean political parties and civil society have raised agendas of universal welfare state and economic democratization through discourse such as constitutional amendment.

Hanging sleepers, which are not fully supported between the sleepers and the ballast, could cause large dynamic forces especially on high speed ballasted track. The dynamic forces resulting from insufficient supporting forces may badly affect the running stability and safety of train. These also accelerate track irregularities and deteriorate track components rapidly. Consequently, thehanging sleepers will lead to sharp increases in track maintenance cost. This paper introduces a rapid and easy method to detect hanging sleepers with portable light falling weight deflectometer (LFWD) and summarizes the results of experiments performed at the high speed ballasted track.

Self-sufficiency ratio of food crops in Korea is estimated under 20% in 2010 because total food consumption including feed will be increased. but food grain production will be decreased. It is necessary to maintain the optimum level of food self-sufficiency rate to secure national food demand/supply balance and non-trade and multiple function of agriculture in Korea. It will be possible to produce more food grains having the acceptable quality if the appropriate policy and cropping techniques are developed and practised in future. Breeding for high yielding varieties should be the first target to raise the production potential of food crops . Number of varieties developed during last 30 years is counted as 353 in food crops. New varieties developed in 1990s showed the higher yield potential and the improved agronomic characteristics compared with 1970s and 1980s varieties. But number of varieties planted on the farmer s field over 5% of national planting area is less than one third of total varieties developed Breeding efforts to maintain planting area of main food crops should be focussed on consumer s demand and farmer s need. They are the best quality variety in each field of crop utilization, the newly designed variety adapting to changes of natural, rural and cropping environment, and the higher yielding variety. It is also needed to develop new quality crop varieties for inducing more consumption of crop grain produced in Korea for direct food or processing. Development of barley varieties for animal feed. high income soybean varieties, high quality wheat variety. and super yielding rice and barley varieties are also needed to keep or maximize national food production potential. In order to establish the appropriate cropping technique for domestic food security, the strong and continuous interest and financial support on crop breeding are required, and the inter-disciplinary and inter-institutionary researches should be strengthened for successful crop breeding.

본 연구는 강우의 자료년수가 부족하거나 미계측 지점에서의 확률강우량 산정을 위하여 확률분포 모수선도를 제시하는 것으로, 30년 이상의 강우기록을 보유한 기상청 산하 58개 강우관측지점에서 12개 지속기간에 대한 연최대치 강우자료를 대상으로 빈도해석을 실시하여 대표확률분포형을 선정하였다. 지점 및 지속기간별로 L-모멘트법을 이용하여 대표확률분포형의 위치, 규모, 형상모수를 계산하고, Kriging방법으로 이를 도시하여 확률분포 모수선도를 작성하였다. 본 연구의 수행으로 인해 얻어진 결과를 요약하면 다음과 같다. 첫째, 전국 58개 지점에 대한 강우분석 결과, 적용한 16개 분포형 중에서 GEV 분포형의 적합도가 가장 우수한 것으로 나타났으며, 둘째, GEV 분포형의 모수를 이용한 지속기간별 확률분포 모수선도를 제시하여 확률강우량을 산정하였다. 셋째, 확률분포 모수선도를 이용한 확률강우량과 기존 연구결과와는 큰 차이가 발생하지 않았다. 넷째, 확률분포 모수선도의 결과를 이용하여 미계측 지점에서의 확률강우량을 재현기간의 제약없이 쉽게 산정할 수 있다. The objective of this study is to produce a probability distribution parameter map for evaluation of probable rainfall quantile in ungauged site. The rainfall data used in this study are annual maximum rainfalls at 58 stations during the period of more than 30 years for 12 durations. The 16 probability distributions which have been widely used in hydrologic frequency analysis are applied to the basic data and to determine the representative appropriate distribution. The location, scale, and shape parameters of the representative appropriate distribution for each station and each duration are calculated using L-moments method. These parameters are contoured using spatial interpolation, based on the geostatistical method of Kriging to produce parameter maps that depict the spatial variation and magnitude of each parameter. The results of this study are as followings; (1) The GEV distribution is determined as the representative probability distribution in Korea. (2) The parameters for any location in Korea can be estimated using the parameter maps and the rainfall quantile is obtained from GEV distribution equation using parameter about the selected rainfall duration. (3) Comparative analysis of the results shows that the probable rainfall quantiles by the parameter maps are little different from those existing researches. (4) In the result by probability distribution parameter map, rainfall quantile is better easy to evaluate in ungaged site without restriction of return period.

This study was conducted to study on the inheritance of growth characters and yield components at the Crop Experiment Station, Rural Development Administration, Suwon, Korea in 1990. Some quantitative characters in F₁ and F₂ of crosses between four determinate soybean cultivars as male parents(Hwangkeumkong, Jangyeobkong, Paldalkong and Suwon 148) and two indeterminate soybean cultivars as female parents(Clark and L63-2404) were investigated and analyzed for combining ability. In F₁ general combining ability(GCA) of male parents indicating principal contribution of additive genetic effects was significant in stem height, number of nodes on mainstem, number of branches, number of nodes per plant, and mainstem dependence rate of number of nodes. GCA of male and female as well as specific combining ability(SCA) was significant in days to maturity, suggesting that additive and non-additive genetic effects of male and female act simultaneously. Both GCA and SCA effects were not significant in yield components. In F₂, both GCA of male and SCA effects were significant in stem height, number of nodes, number of pods, mainstem dependence rate, and grain weight per plant. GCA effect of male was significant in number of branhces. GCA effects of both male and female were significant in days to maturity and 100 seed weight. Non-additive genetic effects were shown in number of pods on mainstem, number of pods per plant and number of grains per plant. The significance and directions of GCA and SCA effects varied according to males and females, generations and relevant characters. According to the estimated GCA, Clark and Deogyukong were found to be desirable parents for greater vegetative growth and yield, whereas Suwon 148 for earlyness, Hwangkeumkong for large seed size, and Paldalkong for high mainstem dependence rate and short stem. The estimated SCA effect for yield and lateness was great in the crosses of L63-2404×Dogyukong and Clark×Suwon 148, while SCA effect for earlyness was large in L63-2404×Suwon 148 and Clark×Dogyukong.
