비폐색이 있는 경우 음성이 변하는 것을 쉽게 느낄 수 있지만, 비폐색 때의 음향학적인 특성에 대하여 알려진 바를 찾기는 쉽지 않다. 저자들은 인위적으로 비폐색을 유발하여 비폐색 부위에 따른 비강자음의 음향학적 변화특성을 파악하고 비음도의 변화 정도를 비교하고자 하였다. 정상비음도를 보이는 성인남녀 각 10명을 대상으로, 2ml의 부피를 갖도록 수술용장갑에 Merocel$^{\circledR}$을 넣은 뒤, 이를 이용하여 ostiomeatal unit(OMU)을 중심으로 전후상하 4부위의 인위적인 비폐색을 유발하여, 비폐색 전과 후의 부위에 빠른 차이틀 비교하였다. /나나/의 발성을 각 조건에서 3회 실시하여, 모음중간의 /ㄴ/중 (CVCV) 안정된 spectorgram소견을 보이는 부위를 선택하여, 해당구간의 제1, 제2, 제3 음형대와 각각의 bandwidth 평균값을 남녀별로 비교하였고, 표준비음비율이 알려진 rabbit, baby, mama 문장을 이용하여 비음비율을 비교하였다. 남녀모두 비폐색전에 비하여 OMU의 앞쪽부위를 막은 경우에 제1음형대가 가장 뚜렷하게 감소되었으며, 비음비율의 유의한 감소를 보였다. 비폐색이 있는 경우, 비강자음 /ㄴ/은 제1음형대를 중심으로 주요변화가 일어남을 알 수 있었으며, 비폐색 부위에 따라 비음비율이나 제1음형대 감소의 정도가 다름을 알 수 있었다.

Park et al. (2012) examined the impacts of coeducation in high school on the college scholastic ability test using random assignment in Seoul high schools. However, the student random assignment in Seoul within a school district was performed only within 30 min commutable areas using public transportation and Park et al. (2012) did not aware of this rule. This paper reexamines the question by matching nearest two single sex schools with a coeducation school within a school district. We found single sex school students achieve higher test score than that of coeducation school for both male and female. The magnitude of test score improvement for female is smaller than that of Park et al. (2012). However, the magnitude for male is bigger than that of Park et al. (2012).

The purpose of this study on effect of preparation for aging on satisfaction of life by difference according to comparison of gender on the analysis. The 3th years additional research and 4th years of Korean Panel of retirement and longitudinal study was used. The sample size of this study was 2,970 for middle aged using based on over 50 years than 64 years. The explanation of the research results are as follows: First, the difference in preparation according to comparison of gender that a statistically significant difference in both men and women. Secondly, the difference in life satisfaction according to gender for both men and women showed that a statistically significant difference. Thirdly, the preparation was confirmed that the results for both men and women is significantly difference comparison of gender differences with respect to the effects preparation for aging on satisfaction of life. As a result, the based on gender through a comparison of the effects preparation for aging on satisfaction of life in accordance with middle-aged ready to raise the preparation and satisfaction of life.

목적 : 발성훈련을 받지 않은 각각의 직업적 음성 과사용집단의 음성분석에 대한 연구는 많이 보고되었지만, 이들 집단간의 음성분석을 통하여 각 집단의 음성문제를 비교한 연구는 미흡하다. 따라서 발성훈련을 받지 않은 직업적 음성 과사용집단의 음성 증상 및 음향학적 분석결과를 정상인과 비교함으로써 각 집단간 음성장애의 양상에 대하여 알아보고자 하였다. 대상 및 방법 : 음성장애에 대한 설문조사, 음향적 분석 및 성대화상술검사를 통하여 직업적 음성 과사용집단으로 분류되는 목사, 여자 교환수 및 고교 남녀교사를 증상 및 이학적 검사상 음성장애 소견을 보이지 않는 성인 남녀와 비교하였다.

The purpose of this study was to examine what errors students made in solving word problems with figures and to compare the problem-solving abilities of boys and girls for each type of word problems with figures. It's basically meant to provide information on effective teaching-learning methods about world problems with figures that were given the greatest weight among different sorts of word problems. The findings of the study were as fellows: First, there was no difference between the boys and girls in the types of error they made. Both groups made the most errors due to a poor understanding of sentences, and they made the least errors of making the wrong expression. And the students who gave no answers outnumbered those who made errors. Second, as for problem-solving ability, the boys outperformed the girls in problem solving except variable problems. There was the greatest gap between the two in solving combining problems. Third, they made the average or higher achievement in solving the types of problems that were included much in the textbooks, and made the least achievement in relation to the types of problems that were handled least often in the textbooks.

Empirical study comparing the leadership styles of women an men is a popular on management in organization. Consistent with study comparing women and men on many organizational behavior, I have identified that leadership style from survey. The this study examined follower's perception of the women and men the leadership in organization. More specifically, I examined how male and female follower evaluated the leadership style and effectiveness of women and man, how these evaluations were affected by the degree of stereotypes of the followers toward gender roles, finally the variables affecting the evaluation of the leadership effectiveness. Total 158 follower's participated in this survey to explore these research questions. The results that female evaluator were evaluated higher in the transformational leadership than male evaluator, while the evaluation for man leader was higher than the woman leader in terms of the transactional and task-oriented leadership style. Also, another analysis the gender difference of the organizational member revealed that woman leader better than man was higher leader relational and transformational leadership. However, both male and female followers who were no gender-difference in decision making work, interpersonal work, relation coordination work, consulting work.
