This paper explores the effects of the 1997 economic crisis on the pattern of socioeconomic differentials in fertility. Based on analysis of data from the 2003 Korea National Fertility Survey, this study focuses on recent changes in the level of fertility according to socioeconomic status of the couple including educational level, occupation, working status, income, etc. Results reveal that the level of fertility of those with the highest education, most prestigious occupation, and employer status are higher than those of the next group in the socioeconomic hierarchy. These findings imply that the straight line inverse pattern of socioeconomic differentials in CEB yielded to a reversed J-shaped curve. However, recent differentials of fertility after the economic crisis were found to contrast with the pattern above. Decrease in fertility has been most drastic among those with a high level of fertility, and relatively slow for those with a low level of fertility. The level of recent fertility turns out to be highest among those with upper-middle socioeconomic status, followed by those with the highest socioeconomic status and those with the lowest status. Policy implications and some comments on current population policies of the Korean government are also presented in this paper.

The purpose of this research is to reveal the difference of teacher-child interaction in relation to professionalism awareness and sensitivity level of early childhood teachers. To this end, we used professionalism awareness, sensitivity, teacher-child interaction as parameters for 226 early childhood teachers in Jeonbuk province. Here are the results : First, we investigated the difference of professionalism awareness, sensitivity, teacher-child interaction in relation to the background of early childhood teachers, and it differs by the age, career, educational level of the teachers. Second, we made group comparison to see the difference of teacher-child interaction depending on professionalism awareness level of teachers, and teachers with high professionalism awareness showed meaningfully higher emotional, verbal, behavioral interaction level than lower group. Third, we made group comparison to see the difference of teacher-child interaction depending on sensitivity level, and teachers of high sensitivity shows meaningfully higher emotional, verbal interaction than lower group. This result could be potential data to ameliorate the quality of teacher-child interaction, and it implies that the improvement of professionalism and sensitivity level could contribute to professional performance capability of teachers.

In this study, the effects of driver's neuroticism on situation awareness(SA), eye movement(EM), and driving performance were examined. In Experiment 1, in which static driving scenes were presented, it was found that the drivers of higher neuroticism showed shorter percentage of dwell time and less percentage of fixation counts for the peripheral area than those of lower neuroticism, although SA scores yielded no difference between the two neuroticism groups. In Experiment 2, differences in the drivers' driving performances as well as SA and EM as a function of neuroticism were compared using driving simulation. The results of Experiment 2 showed the followings. First, contrasting to Experiment 1, the high neuroticism group showed lower SA score than low neuroticism group. Second, the pattern of EM was similar to those of Experiment 1. Third, high neuroticism group deviated more from center of road, and drove slower than low neuroticism group.

When the definition of income and the equivalence scale was applied just as it was in the LIS (Luxembourg Income Study), the adjusted disposable income inequality calculated by Gini coefficients in Korea was 0.358 for the year 2000. Compare to the 1996 figure of 0.298 the increase of income inequality has skyrocketed. In addition, the adjusted market income inequality increased from 0.302 in 1996 to 0.374 in 2000. The disposable income inequality ranked the third and the market income inequality ranked at the mid level in 2000 among OECD countries. One significant finding in this paper was that the difference between the disposable income inequality and market income inequality in Korea is very small compared to those of other OECD countries. The relative poverty ratio, which is calculated by using 40% of the medium income bracket of the disposable income was calculated at 7.6% in 1996 and 11.5% in 2000. The poverty ratio in 2000 for Korea ranked one of the highest in OECD countries, also.

Partial safety factors of the load, resistance, and reliability function are evaluated according to the target probability of failure on sliding mode of monolithical vertical caisson of composite breakwaters. After reliability function is formulated for sliding failure mode of caisson of composite breakwaters regarding bias of wave force, uncertainties of random variables related to loads, strengths are analyzed. Reliability analysis for the various conditions of water depth, geometric, and wave conditions is performed using Level II AFDA model for the sliding failure. Furthermore, the reliability model is also applied to the real caisson of composite breakwaters of Daesan, Dong- hae, and Pohang harbor. By comparing the required width of caisson of composite breakwater according to target probability of failure with the other results, the partial safety factors evaluated in this study are calibrated straightforwardly. Even though showing a little difference on the 1% of target probability, it may be found that the present results agree well with the other results in every other target probability of failure.

The purposes of National Assessment of Educational Achievement(NAEA) are to assess Korean students' achievement of the educational goals as well as to diagnose the trends of educational achievement in order to monitor the quality of education at the national level. We analysed average scores in science achievement and trend of achievement level at the National Assessment of Educational Achievement(NAEA) from the year 2003 to 2006 for 6th, 9th and 10th graders. The results are as follows: For grades 6, 9, and 10, the average scores of NAEA did not tend to increase or decrease. About the trend analysis of gender, females outperformed males for grade 6, but males outperformed females for grade 10. For grade 6, the ratio of females in Advanced level was more than that of the males in the same level. For grades 9 and 10, the ratio of male was higher than the females. For grades 6, 9 and 10, the ratio of males in Below-Basic level was more than that of females in the same level. The results of the educational achievement of urbanization shows that students in rural area scored the lowest. And the ratio of Below-basic level students was highest in rural area. It is needed that educational surroundings be improved to lessen the score difference both between genders and regions. An additional study is needed to used the results of NAEA for the improvement of curriculum and educational policy.

The key feature of the $7^{th}$ Education curriculum, which is applied by order by year from 2000, is represented by differentiated curriculum. In order to embody differentiated curriculum, it is extensively recommended the level-based instruction. Level-based class basically has purposes to give students matched study experiences in accordance with their abilities and to help all students to understand what they have learned through providing differentiated instruction with considering the learners' stand points. The preceding researches have reported many cases about operating methods and educational effectiveness for the level-based instruction. In the meantime, researches about students' acceptances or opinions related to the level-based instruction are not sufficient. In this research, students opinions about level-based instruction are analyzed, based on the distinction of sex and level, and improving operational methods are suggested.

Observations to precise levelling nets contain different types of error because it has been caried out with various instruments and techniques, and also completed through long period. In order to establish a precise levelling nets, therefore, the weight function has to be selected adequately in the adjustment of nets. The purpose of the study is to determine a suitable weight function for the first order geodetic levelling nets in Korea and, therefore, the various numerical tests are performed with different statistical error models. The result of the study shows that the weight function, W＝1/$L^2$ is more efficient than W＝1/L in the first order levelling nets in the Korea.

우리나라는 강수량과 수자원 부존량을 고려할 때 물 부족국가라는 평가를 받고 있다. 홍수와 물이용 등에 대한 국가적 평가나 물환경에 대한 평가지표는 개발된 바 있으나 물과 관련된 복지수준을 평가할 수 있는 지표에 대한 연구는 부족한 실정이다. 최근의 국내외 연구에서 물의 공급에 대한 만족도나 홍수에 대한 안정성 등에 대한 평가수단으로 국제적으로 물 빈곤지수 등이 제시되어 있지만, 물의 이용에 관한 복지적 개념이나 평가에 대한 연구는 기초적인 수준에 머물러 있는 실정이다. 본 연구에서 각 시군에서 매년 발간되는 통계연보를 이용하여 물의 공급과 이용 그리고 물 공급 인프라, 물 사용료, 하수처리비용 등과 같은 요금체계 등을 감안한 대구광역시와 경상북도 23개 시군에 대하여 물복지 수준에 관한 평가분석을 수행하였다. 그 결과 수자원분야 지표에서는 울진군, 기반시설 분야지표에서는 대구광역시, 용수공급 분야에서는 영천시, 사용자 분야에서는 영덕군, 경제성 분야에서는 봉화군이 가장 물복지 수준이 좋은 것으로 분석되었으며, 전체적으로 가장 물복지 수준이 좋은 곳은 문경시로 분석되었다. 또한 도시화율이 높고 인구가 많은 곳이 기반시설 분야에서는 우수한 편이나 전체적으로는 오히려 대도시보다는 중소도시의 물복지 수준이 높은 것으로 밝혀졌다.
