Background and Purpose Caregivers experience tremendous social, financial, physical, and psychological burdens in caring for people with dementia. This study aimed to determine the efficacy of a multicomponent therapeutic intervention program for the caregivers of people with dementia (CGPWD) through a multicenter clinical trial: the intervention programcaregivers of people with dementia study. Methods The 38 caregivers of dementia patients at 8 sites were randomized into 2 groups: treatment (n=19) and control (n=19). The treatment group received the intervention program for 8–10 weeks, including one group session for dementia education and three individual sessions (on cognitive behavioral therapy, coping with stress, and stress management) and single targeted training for daily activities. The Korean version of the Zarit Burden Interview (ZBI-K) and the Geriatric Depression Scale (GDS) were evaluated at pre- and postintervention as primary efficacy measures. Results The treatment group displayed significant improvements in scores on the ZBI-K and GDS. The ZBI-K score at postintervention was significantly reduced in the treatment group compared to that in the control group [6.2-point decrease vs. 3.7-point increase, t(37)=-2.9, p< 0.01]. There was a significant difference in the GDS score between the treatment and control groups [2.2-point decrease vs. 1.3-point increase, t(18)=2.5, p<0.05]. Conclusions The findings of this study imply that a multicomponent therapeutic intervention program is effective in reducing the burden experienced by and depression among CGPWD. Further research is warranted to investigate the long-term effects of the intervention program for CGPWD.

나노기술의 실제적인 응용을 위해 응집되지 않은 나노입자 상태를 얻는 것이 매우 중요하다. 나노입자를 사용하는 제품의 기능성을 향상시키기 위해, 그들의 합성 과정에서 입자 크기 분포의 더 정밀한 제어가 요구된다. 그러나 합성된 나노입자들은 물리적 혹은 화학적인 이유로 응집되기 쉬워 나노입자의 고유한 특성이 가려져 실제적인 응용에 있어서 문제를 일으킨다. 본 연구는 단분산된 나노입자만을 분리하기 위하여 초음파 무화 효과에 의한 무화입자를 분리장으로 사용한 나노입자 분리방법을 제안하였다. 0.002 wt. %의 농도를 갖는 $TiO_2$ 나노입자 현탁액을 무화시켜 분리포집된 현탁액에 포합된 나노입자들의 입도분포를 측정하였다. 그 결과들로부터 제안된 방법을 이용하여 단분산 입자의 분리 포집이 가능함을 확인 할 수 있다. It is very important to obtain non-agglomerated nano particle state for practical application of nano technology. In order to improve the functionality of products using nano particles, more precise control of particle size distribution is required in their synthesis process. However, synthesized nano particles are agglomerated easily due to physical and chemical reasons, and it then veils unique properties of the nano particles and causes some troubles in their practical application. In this study, a separation method for nano particles from suspension by using the droplets as the separation space was proposed. Using the suspension of 0.002 wt. % with $TiO_2$ powder, the particle size distribution of nano particles in the recollected suspension was measured. From the results, it was confirmed that it is possible to separate and to recollect the nano particles monodispersed by using the suggested method.

Purpose: The purpose of this research was to figure out the degree of female college students’ dysmenorrhea and factors affecting these diseases. Methods: The study subjects were 800 female college students in 3 schools located in D city. The data were collected by a self-administered questionnaire between May 29 and June 30, 2017. The data was analyzed through Mean±SD, t-test, ANOVA, Pearson's correlation coefficient, multiple logistic analysis using IBM SPSS 20. Results: The results of this study were as follows. Students who had moderate amount of menstruation(AOR:8.461, 95% CI:2.217-32.294, p=.002), or family history(AOR:.3.658, 95% CI:.2.047-6.537, p<.001) appeal dysmenorrhea. However, girls who had satisfied(AOR:.416, 95% CI:.201-.862, p=.018) or moderate sleep quality(AOR:.455, 95% CI:.230-.901, p=.024) among health behavior had less possibility of dysmenorrhea than who had unsatisfied sleep quality. Conclusion: This study suggests that health promoting interventions for female college students need to be developed and adapted, improving life habits to decrease dysmenorrhea.
