본 연구는 여성이 가족과 일을 병행하려 할 때 안게 되는 이중부담의 양과 유급노동시간과 무급노동시간에 영향을 주는 변수들의 차이를 통해 남성과 여성의 시간사용구조를 살펴보고, 이중부담이 노동시간양${\cdot}$노동시간대${\cdot}$노동장소로 나타나는 여성 유급노동시간에 미치는 영향을 알아보았다. 자료는 통계청의 1999년 생활시간조사 원자료를 이용하였다. 분석결과 맞벌이 가구의 여성은 남성보다 하루 평균 1시간 51분 많은 총노동시간을 가지면서 주당 약 13시간의 이중부담을 가지고 있었다. 이것은 만성과 여성의 노동시간사용구조가 서로 다르기 때문이었다. 즉, 여성은 경제활동에 참여한다할지라도 무급노동시간의 89%를 책임지고 있었으며 여성의 노동시간은 가족상황에 의해 영향을 받는 젠더화된 생활시간사용구조를 가지고 있었다. 또한 기존연구결과와 다르게 가내하청/재택근무, 자영, 무급가족종사와 같은 종사상지위와 미취학자녀의 존재는 여성에게 유급노동시간을 조절하는 기재가 되지 못했고 무급노동시간을 늘리는 역할을 할 뿐이라는 점이 한국사회 여성의 이중부담을 가중시키고 있는 것으로 보인다. 또한 맞벌이가구 여성은 무급노동에의 일차적 책임으로 남성보다 야간유급노동이나 휴일유급노동시간을 줄이고, 단시간노동을 선택하며, 집안에서의 유급노동시간을 길게 하면서 가족생활시간을 확보하는 유급노동시간 조절전략을 사용하고 있었다. 이러한 노동방식은 노동시장에서 여성노동의 불안정성을 만들어내고 주변화시키는 요인이다. 그러나 또 한편으로 서구사회와 비교하면 한국사회에서 여성이 경제활동을 하기 위해서는 광범위한 야간노동과 휴일노동, 장시간노동이라는 남성적 노동조건을 받아들이고 있는 것으로 보인다. 특히 판매/서비스직의 자영자와 무급가족종사자 여성들, 가내하청이나 재택근무를 하는 임금근로자 여성들, 학력이 낮은 기능/조립직과 단순노무직 여성들은 야간노동이나 휴일노동, 집안에서의 유급노동시간이 길뿐 아니라 절대적인 유급노동시간과 무급노동시간도 길게 나타났다. 그러나 미취학자녀의 존재가 이러한 여성적 유급노동시간의 특징에 영향을 주는 것은 아니었다.

This study attempted to verify the relationship among Job Attitude, Personality and Demographic Characteristics according to Dual Commitment Type. The groups were named 'very high dual commitment group(both highly committed to the organization and union)', 'normal dual commitment group(average level of commitment to both of them)', 'resisting dual commitment group(no commitment to both of them)', 'organization commitment group(only committed to organization)', 'union commitment group(only committed to union)'. This research was analyzed by 388 Hyundai and Kia motor company members and 'very high dual commitment group' and 'organizational commitment group' showed the highest Job Satisfaction and Job Involvement. Through group segmentations considering sub-concepts could contribute to design a strategy to increase the company's competitiveness in aspects of the direction to the HR policy.

This study investigated results of bilingual learning of mathematics in teaching quadratic functions at an international high school in South Korea. Unlike a Korean traditional public school, this international school has provided bilingual learning. 10th grade students enrolled two math classes, Algebra II that was taught in English through CCSS and High School Mathematics I that was taught in Korean through the Korean National Math Curriculum. In order to collect information on students' behaviors and math achievement, we analyzed students' academic back grounds, mathematical abilities, results of interviews, observations, questionnaires and assessments. The results of this study include specific benefits. Bilingual learning of mathematics is effective as a method to improve Korean students' mathematical abilities and attitudes as well as positive influence on Korean mathematics education.

온도의 계측에는 열팽창(Thermal expansion), 열전기(thermoelectricity), 전기저항(resistance)등의 원리를 이용하고 있다. (1) 열팽창식 온도계 물체의 열팽창 원리를 이용하는 온도계에는 두 금속의 열팽창 계수의 차이를 이용하는 바이멜탈 온도계, 액체의 팽창을 이용하는 유리 온도계, 기체 압력이 온도에 비례하는 것을 이용하는 압력식 온도계 등이 있으나, 이중에서 유리 온도계가 가장 널리 사용되고 있다.(중략)

Objective: Small orthodontic mini-implants are useful as anchorage. However they have some weaknesses such as loosening. This study was carried out to analyze the mechanical effects of the dual pitch and diameter on the insertion and removal torque of mini-implants. Methods: The threads of mini-implants were mono and dual pitch. The diameters of mini-implants were 1.4 mm and 1.6 mm. Four groups were tested (mono 1.4 mm, mono 1.6 mm, dual 1.4 mm and dual 1.6 mm). All were inserted and removed on polyurethane foam with the torques being measured. Results: The maximum torque of the dual pitch groups was higher than the mono pitch groups during removal but lower during insertion. The maximum torque of the 1.6 mm diameter groups was higher than the 1.4 mm diameter groups during insertion and removal. The dual pitch 1.4 mm group showed the lowest insertion torque but had similar or superior levels of removal torque to that of the mono pitch 1.6 mm group. Conclusions: The dual pitch especially showed a continuous high removal torque after the peak. Despite the small diameter, the dual pitch might improve the initial mechanical stability.

This study used data from the 10rd and 15th year of the Korean Welfare Panel to evaluate the effects of the Energy Voucher Program(EVP) on the consumption and expenditure of EVP users' households. The study consisted of program group using EVP and control group not using. Chi-square and t-test were used for the characteristic differences among the groups, and the difference of consumption expenditure was identified by multiple regression analysis. As a result, EVP had a statistically significant effect on the health care costs of EVP users' households, resulting in an increase in health care costs(𝛽=3.06). However, there was no statistically significant effect on the total cost of living, basic cost, education cost, and recreation/entertainment cost. Therefore, in order to increase the effectiveness of the EVP system, it is required to improve the EVP system by expanding the level of benefits and easing the qualification standards for the eligibility for benefits.

The purpose of this study is to examine whether the national pension affects the life satisfaction of old age, using the first and third-wave data from the Korean Retirement and Income Study. The study analyzes the relationship between the national pension and life satisfaction, using several operational definitions of these two variables. This study utilizes the Difference-in-Difference(2D) models and panel data analysis. The main results are : First, the result of simple 2D shows that there is not significantly difference between the pensioner and that of non-pensioner. Second, the result of 2D regression also shows that pension is not significantly associated with life satisfaction of the old age. Lastly, the result of fixed-effect model confirms that the national pension does not have a statistically meaningful effect on the life satisfaction, controling for the unobserved characteristics of the old age. This study also conducts sensitivity analysis and discusses policy implications.
