  • Egg distribution and mortality rate for anchovy, Engraulis japonica, and sardine, Sardinops melanosticta, during spring in the southern waters of Korea were estimated using the data from ichthyoplankton surveys conducted from March to April 1991, 1992. Anchovy and sardine eggs were found simultaneously in high density in the southwestern waters of Tsushima Island during March 1991 and late in March${\sim}$early in April 1992. Distribution areas of anchovy and sardine eggs in 1992 was extended to the middle area of the southern waters compared to 1991. Sea surface temperatures in the survey area ranged from 8.6 to $17.8^{\circ}C$. Anchovy and sardine eggs occurred with high densities between $14^{\circ}$ and $15^{\circ}C$. Instantaneous mortality coefficients were estimated to be 0.268/day for anchovy, and 0.132/day for sardine during $4{\sim}15$ March in 1991.

  • The study examined the shift in the attitudes of college students regarding familial gender roles between 1991 to 2002. The results are as follows. (a)There were changes toward the egalitarian direction in familial-related gender role attitudes between 1991 and 2002, in both male and female college students. (b)Yet, despite of these changes toward egalitarianism, Female colleges students exhibited the more egalitarian familial gender role attitudes than their male counterparts, both in 1991 and 2002. (c)The shift toward more egalitarian attitudies was most pronounced in couples' equal participation in decision making, the sharing of housework, and women's participation in labor force. however, the shift toward egalitarian attitudies was less pronounced in the issues concerning outside home activities of the mothers with infants. Based on the results, implication for the future family and family education programs were discussed.

  • 이 연구는 Hewitt과 Flett(1991c), 이기종(2006)이 제안한 완벽주의 척도 연구모형의 타당도를 확인적 요인분석을 통해 검증하고, Hewitt과 Flett(1991c)이 개발한 완벽주의 척도의 문항이 몇 개의 요인으로 구성되는지 알아보기 위해 탐색적 요인분석을 실시하였다. 확인적 요인분석 결과 Hewitt과 Flett(1991c), 이기종(2006)이 각각 제안한 연구모형과 수집된 자료가 잘 합치하지 않았다. 따라서 자료에 모형이 잘 맞도록 모형을 수정해야 하고, 의미 없는 자유모수가 모형에서 나타나지 않도록 모형을 다시 설정해야 함을 알 수 있다. 또한 Hewitt과 Flett(1991c)이 개발한 완벽주의 척도의 탐색적 요인분석을 통해 완벽주의 척도의 각 문항들이 완벽주의를 측정하는데 있어서 단일요인으로 제 기능을 하기 보다는 여러 문항에 걸쳐 공통요인이 존재함을 알 수 있다. 따라서 확인적 요인분석과 탐색적 요인분석을 통해 Hewitt과 Flett(1991c)이 개발한 완벽주의 척도가 측정하는 요인은 3개 요인으로 설명될 수 없다고 판단된다. 그러므로 Hewitt과 Flett(1991c)이 개발한 완벽주의 척도의 측정 문항이 수정되어야 하고, 나가서 우리의 사회 문화적 실정을 고려한 완벽주의 척도의 개발이 시급함을 알 수 있다.
