중국은 1979년 이후로 한자녀정책을 주요 정책으로 추진해왔고, 이로 인해 저출산 사회로 전환되었 다. 또한 발전된 보건과 의료기술로 노인들의 수명이 급격히 늘어나면서 중국의 고령화율 역시 급증하 였다. 이렇듯 수발이 필요한 고령인구는 급증하였으나, 현재 중국에는 이들을 돌볼 돌봄인력이나 인프 라가 턱없이 부족한 상태이다. 본 연구는 이러한 노인수발 문제를 해결하기 위한 제도적 해법으로 노인 장기요양보험에 주목한다. 본 연구는 중국 노인장기요양보험제도의 도입과정과 시범사업 등을 살펴본 후, 노인장기요양보험제도 도입의 선도국가인 한국으로부터 어떤 정책교훈을 얻을 수 있는지 살펴보았 다. 본 연구는 연구를 수행함에 있어 주로 문헌연구 분석을 사용하였다. 본 연구는 두 가지 의의를 갖는다. 첫째, 중국 노인장기요양보험제도의 시범사업을 개관함으로써 그 흐름은 물론 그에 관한 기초 자료를 제공하고 있다. 둘째, 중국의 노인수발 문제를 연구함에 있어 기존 연구들에서 찾아볼 수 없는 비교사회정책학적 접근법, 특히 동아시아 사회복지에 대한 비교연구를 수행하였다.

In order to examine the effects of four different light spectra (white, red, green, and blue) on the oocyte maturation, the change of reproductive parameters, via brain-pituitary-gonad (BPG) axis in grass puffer, were investigated. After exposure four different light spectra for 7 weeks, the abundance of gonadotropin-releasing hormone (GnRH) mRNA which is a type of seabream (sbGnRH) and two different subunit of gonadotropin hormones mRNAs, follicle-stimulating hormone (fshβ) mRNA and luteinizing hormone (lhβ) mRNA, were analyzed in the brain and pituitary. Histological analysis showed that the mature oocyte ratio in the green spectrum was higher than other light spectra-exposed groups. Gonadosomatic index (GSI) and oocyte developmental stage were also investigated in the gonad based on histological observations. GSI value with the presence of yolk stage oocytes was significantly increased in the green spectrum-exposed group when compared to that of the other light-exposed groups (white, red, and blue) (p˂0.05). The abundances of sbGnRH mRNA and fshβ mRNA in the green spectrum-exposed group were also significant higher than those of the other light spectra-exposed groups (p˂0.05). These results indicate that the maturation of oocyte in grass puffer can be accelerated by exposure to the spectrum of green. To better understand the molecular mechanism for the maturation of oocyte in grass puffer, further study examining the relationship between oocyte development and its related genes is required.

Gonadosomatic index (GSI) and oocyte developmental stage were also investigated in the gonad based on anatomical- and histological observations. GSI value was significantly increased in the green spectrum-exposed group when compared to that of the other light-exposed groups (i.e., white, red, blue), with the presence of yolk stage oocytes (p˂0.05). The abundances of sbGnRHmRNA and fshβ mRNA in the green spectrum-exposed group were also significant higher than those of the other light spectra-exposed groups(p˂0.05). However, there was no significant difference between the abundances of lhβmRNA in all light spectra-exposed groups. These results indicate that the maturation of oocyte in grass puffercan be accelerated by exposure to the spectrum of green. The sbGnRHmRNA and fshβ mRNA may play an important reproductive parameters role in the initiation of maturation of oocyte. To better understand the molecular mechanism for the maturation of oocytein grass puffer, further study examining the relationship between oocyte development and its related genes (e.g., sbGnRHmRNA and fshβmRNA) is required.
