평균 3.4%인 오프라인 DM의 응답률은 앞으로 더욱 낮아질 수 있지만 하이테크로 무장한 각종 디지털 채널을 통한 마케팅 활동과 비교하면 여전히 높은 수준이다. 그렇지만 DM에 대한 ROI(투자수익률)의 가시적인 성과에 대해서도 차분히 따져볼 필요가 있다.

국회에서의 국방예산안 심의과정에서는 예년에 비교할 수 없을 정도로 심층깊은 논의가 이루어졌을 뿐만 아니라 율곡예산에 대해서도 세부적인 질의와 검토가 이어짐으로써, 향후에는 예산소요에 대한 명확한 근거와 논리가 뒷받침되지 않고는 적정수준의 국방비 획득이 결코 용이하지 않을 것임을 예고하였다.

This study investigated how latent groups depend on the longitudinal trajectories observed in fathers' involvement in parenting over a five year period, and the study also determined differences in children's behavioral problems and mother's parenting stress, marital satisfaction, and depression among these groups. By utilizing 1,316 sets of data from 1st to 5th Panel Survey of PSKC beginning in 2008, we examined the patterns of the latent groups and the differences among them. The results showed that, first, a changing pattern of fathers' involvement in parenting is classified into four groups: a low-stable group, a decreasing group. a middle-high changeable group, and a highest changeable group. According to the results of the latent groups, the fathers' involvement in parenting commonly started to decrease at the children's age of 4 years old. Second, problematic behaviors of children appeared more from the fathers in the decreasing group. Third, parenting stress, marital conflict, and depression were more often found in the low-stable group that in the decreasing group. the middle-high changeable group and the highest changeable group (in that order), while marital satisfaction showed a completely opposite pattern. Based on these results, political intervention and the future direction of research for fathers' involvement in parenting are needed in order to increase better behaviors of their children as well as the psychological well-being of their mothers.
