황우원ㆍ김기진. 정상인과 비만인의 웨이트 트레이닝시 세트 간 휴식시간 차이에 따른 혈중 지질변인 농도 및 신체구성의 변화, 운동과학, 제13권 제1호, 87-100, 2004. 본 연구의 목적은 정상인과 비만인의 웨이트 트레이닝시 세트간 휴식시간 차이에 따른 혈중 지질변인 농도 및 신체구성상 특성의 변화를 분석함으로서 정상인과 비만인들에게 건강관리 및 비만처치를 위한 보다 적절한 웨이트 트레이닝 프로그램을 제시하기 위한 근거를 제공하고자 한다. 피험자는 남자대학생을 정상인Ⅰ(그룹-Ⅰ: 체지방율 20%미만-세트간 휴식시간 40-50초), 정상인Ⅱ(그룹-Ⅱ : 체지방율 20%미만-휴식시간 1분 30초-2분), 비만인Ⅰ(그룹-Ⅲ : 체지방율 25%이상-세트간 휴식시간 40-50초), 비만인Ⅱ(그룹-Ⅳ : 체지방율 25%이상-세트간 휴식시간 1분 30초-2분) 등의 4그룹으로 구분하여 각 6명씩 총 24명으로 구성하였다. 8종목 24세트의 웨이트 트레이닝을 12-15RM의 부하 및 주 3회 빈도로 8주동안 실시하여 대퇴의 근육 및 지방 면적, 신체구성 및 혈중 지질농도의 변화를 분석하였다. 좌측 근육면적은 그룹별 시기간에 4그룹 모두에서 유의한(p<0.05) 차이를 나타냈으며, 좌측 지방면적은 그룹별시기간에 있어서 4그룹 모두에서 유의한(p<0.05) 차이를 나타냈으며, 우측 지방면적은 그룹-Ⅰ 및 Ⅲ에서 트레이닝후 유의하게(p<0.05) 감소하였다. 제지방량은 그룹별 시기간 비교에서 그룹 Ⅱ 및 Ⅳ는 트레이닝후 유의하게(p<0.05) 증가하였다. 혈중 지질관련 변인중 혈중 TC 및 LDL-C 농도는 유의한 변화가 없었으며, HDL-C 농도는 트레이닝후 그룹-Ⅰ, 그룹-Ⅲ 및 그룹-Ⅳ에서 유의하게(p<0.05) 증가하였다. 또한, 중성지방 농도는 그룹-Ⅲ에서만 트레이닝후 유의하게(p<0.05) 감소하였으며, TC/HDL-C 비율은 그룹-Ⅰ, 그룹-Ⅲ 및 그룹-Ⅳ에서 유의하게(p<0.05) 증가하였다. 혈중 지질변인의 변화는 HDL-C 및 중성지방 농도, TC/HDL-C 비율 등의 변화에서 세트간 휴식시간을 짧게 적용한 경우가 웨이트 트레이닝 효과가 크게 나타난 것으로 간주된다. 이상의 연구결과를 요약하면 세트간 휴식시간을 40-50초로서 짧게 적용한 경우가 1분 30초-2분을 적용한 경우보다 체지방량 감소 및 혈중 지질농도 변화에 대해서 긍정적인 영향을 미친 것으로 간주되며, 제지방량 증가를 위해서는 휴식시간을 길게 가질 필요성이 있는 것으로 생각된다. Hwang, W.W., Kim, K.J. Change of blood lipid profiles and body composition following a different set interval during weight training in obese. Exercise Science, 13(1): 87-100, 2004. The purpose of this study was to compare the changes of muscular and fat areas of thigh, body composition, and blood lipid concentration according to the set interval of weight training, for the presentation the appropriate basis of the weight training program in normal and obese subjects. The subjects were consisted of 4 groups of male university students(Group-Ⅰ:%fat less than 20% and 40-50 sec of break time between sets, Group-Ⅱ:%fat less than 20% and 90-120 sec of break time between sets, Group-Ⅲ:%fat more than 20% and 40-50 sec of break time between sets, Group-Ⅳ:%fat more than 20% and 90-120 sec break time between sets). Weight training of 8 items was controled by the intensity(12-15RM) and frequency(3/week) during 8 weeks. Muscular area of thigh was no significant difference by groups and time, but left muscular area of thigh had the significance (p<0.001) by time. The changes of body composition were the significant(p<0.001) differences by groups and time. There was a significant(p<0.001) difference between the right and left fat areas by groups and time, respectively. Fat mass in Group-Ⅱ and Group-Ⅳ increased significantly. Therefore the fat mass was a higher change in short rest interval, but lean body mass was a higher change in long rest interval. HDL-C and LDL-C concentrations had no difference between groups but significance(p<0.001) by time. There were significant changes of TG and HDL-C concentrations in Group-Ⅰ and Group-Ⅲ, and the shorter rest interval is more effective. In the results of this study, weight training program with the 40-50sec rest interval between sets showed more positive impacts on the changes of muscular and tat areas of thigh, body composition, the concentration of blood lipid profiles than those with 90-120 sec rest interval. And the 40-50 sec rest interval between sets showed more effective method on the change of lean body mass after weight training.

진로진학상담교사의 직무수행수준과 진로교육으로 인한 변화 사이의 관계: 관리자 및 동료교사들의 관점을 중심으로

황우원,김주후 한국진로교육학회 2017 진로교육연구 Vol.30 No.4

The purpose of this study is to analyze the level of job performance of career guidance teachers from the perspective of school administrators and peers and to explore the relationship between job performance level and changes with career education. We selected 100 middle and high schools representing Gyeonggi province, surveyed 71 school administrators and 261 peers, and analyzed its results. The main results of this study are as follows. First, the evaluation average school administrators and peers made on the job performance level of career guidance teachers was marked 3.94, which is relatively high. And it is found that career guidance teachers are relatively good at performing the jobs related to curriculums or teaching, still they have difficulty in communicating and cooperating with other education bodies and in fulfilling student-customized guidance counseling(career coaching). Second, the evaluation average school administrators and peers made on the changes with career education was marked 3.85, which is relatively high. Third, there is a high positive relationship between the job performance level of career guidance teachers and the degree of change with career education. And it is discovered that among career guidance teacher's jobs, the jobs that clearly reveals the changes with career education are ‘design and implementation of career search activity inside and outside school’, ‘general management of the training for teachers to enhance career education competence’, ‘support for writing career and learning plan’, and ‘regional and institutional network management for career education-related education donation’. This proves that it is quite necessary for career guidance teachers to make more efforts to focus on the jobs of communicating and cooperating with other education bodies. The result of this study is significant in that the job performance level of career guidance teachers was analyzed and the change with career education was interpreted from the perspective of school administrators and peers who keep a close watch on them, not from the perspective of themselves, career guidance teachers. 본 연구의 목적은 관리자 및 동료교사의 관점에서 바라본 진로진학상담교사의 직무수행수준에 대해서 분석하고 직무수행수준과 진로교육으로 인한 변화 사이의 관계를 탐색하는 데 있다. 이를 위해서 경기도 전체를 대표할 만한 중고등학교 100개교를 선정하여 관리자 71명, 동료교사 261명을 대상으로 설문을 실시하고 결과를 분석하였다. 이 연구의 주요 결과는 다음과 같다. 첫째, 진로진학상담교사의 직무수행수준에 대한 관리자 및 동료교사의 평균은 3.94점으로 비교적 높은 편이었다. 또한, 진로진학상담교사는 교육과정이나 수업과 관련된 직무는 다른 직무에 비해 잘 수행하고 있지만 학생 대상의 맞춤형 진로지도나 다른 교육주체들과 소통하고 협력하는 직무들에 대해서는 상대적으로 어려움을 겪고 있는 것으로 드러났다. 둘째, 진로교육으로 인한 변화에 대한 관리자 및 동료교사의 인식 평균은 3.85점으로 비교적 높게 나타났다. 셋째, 진로진학상담교사의 직무수행수준과 진로교육으로 인한 변화정도 사이에는 높은 정적상관이 있는 것으로 나타났다. 그리고, 진로진학상담교사의 직무 중에서 진로교육의 변화를 잘 설명해 주는 직무는 ‘교내외 진로탐색 활동 기획 및 운영’, ‘교원 대상 진로교육 역량강화 연수 총괄’, ‘진로 및 학습 계획서 작성 지원’, ‘진로교육 관련 교육기부 등 지역 및 기관 네트워크 관리’순으로 나타났다. 이는 진로진학상담교사가 다른 교육주체들과 소통하고 협력하는 직무에 좀 더 힘써주기를 바라는 것으로 해석할 수 있다. 본 연구의 결과는 진로진학상담교사 당사자의 관점이 아닌 가까이에서 지켜보고 있는 관리자와 동료교사의 관점에서 진로진학상담교사의 직무수행수준을 분석하고 진로교육의 변화를 해석하였다는데 의의가 있다.

황우원(Woowon Hwang),김주후(Juhu Kim) 한국진로교육학회 2019 진로교육연구 Vol.32 No.2

본 연구의 목적은 진로진학상담교사의 직무수행과 학교 진로교육 목표 달성 간의 관계는 어떠한지 밝히는 것이다. 또한, 직무수행의 유형은 어떠한지, 직무수행유형과 학교 진로교육 목표 달성 간의 관계는 어떠한지를 밝히는데 있다. 이를 위해서 경기도 내 중학교에 근무하는 진로진학상담교사 전체를 대상으로 온라인 설문조사를 실시하였고, 314명의 설문자료를 최종 분석 자료로 사용하였다. 이 연구의 주요 결과는 다음과 같다. 첫째, 진로진학상담교사의 직무수행과 학교 진로교육 목표 달성 간에는 높은 정적 상관관계가 있는 것으로 나타났다. 또한, 학교 진로교육 목표 달성에 가장 큰 영향을 미치는 직무로는 ‘지역사회 및 기관과의 네트워크 관리’로 나타났다. 둘째, 진로진학상담교사의 직무수행유형은 크게 4개로 군집화 되었다. 군집1은 ‘직무수행정도가 전체적으로 우수한 집단’으로 ‘고수준유형’, 군집2는 ‘지역사회연계에 주력하는 집단’으로 ‘지역사회연계유형’, 군집3은 ‘지역사회연계는 소극적이면서 수업과 상담 등 교내 진로활동에 주력하는 집단’으로 ‘교내활동유형’, 군집4는 ‘직무수행정도가 전체적으로 낮은 집단’으로 ‘저수준유형’으로 명명하였다. 셋째, 직무수행유형에 따라 학교 진로교육 목표 달성정도에 유의미한 차이가 있는 것으로 나타났다. 직무수행정도가 가장 높은 ‘고수준유형’이 목표 달성정도가 가장 높았고, 직무수행정도가 가장 낮은 ‘저수준유형’이 목표 달성정도가 가장 낮았다. 본 연구는 진로진학상담교사의 직무수행을 유형화시켜 직무수행의 질적인 구조를 파악하고, 진로진학상담교사의 직무수행유형에 따라 학교 진로교육 목표 달성 정도에 차이가 있음을 규명하였다는 점에서 의의가 있다. The purpose of this study is to clarify the correlation between the type of the job performance of career guidance teachers and the achievement of the goal of school career education. To achieve the purpose of this study, an online survey was conducted of the entire career guidance teachers working at middle schools in Gyeonggi Province, and the survey data collected from 314 career guidance teachers were used as the final study material. The results are as follows. First, there was a high positive correlation between the job performance of career guidance teachers and the achievement of the goal of school career education. Second, the job performance of career guidance teachers were clustered into four types. Type 1 was named ‘high-level type’ group with the excellent job performance overall. Type 2 was named ‘local community networking type’ group focusing on the local community linkage. Type 3 was named ‘school activity type’ group passive in the local community networking and focusing on school career activities such as classes and counseling. Type 4 was named ‘low-level type’ group with the low level of job performance overall. Third, there was a meaningful difference in the achievement of the goal of school career education in accordance with types of job performance. The highest level of achievement was made by the ‘high-level type’ with the highest job performance and the lowest level of achievement was made by the ‘low-level type’ with the lowest job performance. This study is meaningful in that it verified the qualitative structure of job performance by stereotyping the job performance of career guidance teachers, and found the differences in the achievement of the goal of school career education in accordance with the types of job performance.

Kim, K. J., Hwang, W. W., & Oh, K. S. Change of Blood Metabolic Variables during Submaximal Exercise at Mean and High Temperature in the Obese. Exercise Science, 11(1): 1-15, 2002. This study attempted to compare the change of blood metabolic variables and electrolyte concentration during submaximal exercise for 30 minutes at normal temperature (21±1℃ for temperature, 65±2% for humidity) and high temperature (40±1℃ for temperature, 65±2% for humidity) with 60% exercise intensity of VO_2 max of obese and normal persons, in order to examine whether the obese persons can gain positive effects for obesity treatment when the obese persons perform exercises at normal and high temperature. Hematocrit increased more significantly in exercise than resting values and it increased more significantly in the obese persons (p<0.05) at normal temperature than the normal persons. It was found that blood glucose concentration showed a main effect for time[F(5, 40)=15,700, p<0.001], and time and group[F(5, 30)=4.273, p<0.01] by three-way ANOVA, and increased significantly during recovery phase than resting values. Blood FFA concentration increased more significantly during exercise and recovery phase than resting values, and decreased again 30 minutes of recovery phase. Also, it was found that blood insulin concentration showed a significant effect for time[F(5, 40)=1188.217, p<0.05], and decreased more significantly during exercise than resting values, and increased again during recovery phase. Hood cortisol concentration showed a significant effect for time[F(5, 40)=3.332,, p<0.05], and increased significantly till 15 minutes during exercise and recovery phase than resting values and decreased after 30 minutes of recovery phase. Blood sodium concentration decreased during exercise much more than resting values and decreased rapidly during recovery phase. Blood potassium concentration increased during exercise than resting values, and decreased again during recovery phase, while chloride concentration increased till 10 minutes during exercise than resting values, and decreased continuously during recovery phase. Findings of this study were that some drink should be taken in exercise due to marked increase of hematocrit, and loss of water of the obese might be higher than normal persons somewhat during exercise. The obese persons showed high dependence on fat metabolism during continuous exercise.

Objectives The purpose of this study is to explore the problems of the standard-based assessment, which is expanded in the high school credit system and the 2022 revised curriculum, and the direction of desirable college admission operation. Methods To this end, a survey was conducted on high school teachers and university admissions officers, and the questionnaire was composed of a background variable and a total of 14 questions in 4 areas and was prepared on a 5-point Likert scale. For the collected data, descriptive statistics, t-test, cross-analysis, and one-way variance analysis were conducted. In-depth interviews with experts (two high school teachers and admissions officers each) were conducted to secure the validity and reliability of the survey results. Results First, the expansion of the standard-based assessment will reduce the student sub-curricular screening and expand the comprehensive student sub-curricular screening. Second, when the standard-based assessment is expanded, the boundary between the student sub-curricular screening and the student sub-curricular screening is blurred, and it is necessary to introduce qualitative evaluation in the student sub-curricular screening. Third, admissions officers were more negatively aware of the operation of subject selection and grade inflation according to student wishes than teachers, and teachers preferred to introduce or strengthen interview evaluation and admissions officers preferred to introduce or strengthen the minimum academic standards for the CSAT as a way to compensate for the difficulty of discrimination in student sub-curricular evaluation. Conclusions When applying the standard-based assessment requires additional factors, specific methods, specific methods should be applied depending on the characteristics of the universities of universities should be applied according to the characteristics of universities. In order to Evaluation of Desirable University Admissions high school life records, and universities need to strengthen the competitiveness of the evaluation of the evaluation.
