지난 2005년 10월 노인수발보장법 공청회 이후 동 제도에 관하여 노인복지 현장, 학계, 시민사회단체, 경제계 등 우리사회의 주요 구성체 모두가 의견을 제시하고 있다. 노인수발보장제도는 우리나라 복지제도의 틀(framework)을 크게 변화시키는 제도로 각계각층의 관심을 불러일으키고 있다. 작년2월 공적노인요양보장제도 실행위원회가 「공적노인요양보장제도 실시모형」을 제출한 이후 보건복지부는 5월 「노인요양보장제도 추진방안」을 제시하였고 10월에는 「노인수발보장법 제정안」을 국회에 제출하였으며, 12월에는 한 심포지엄에서 보건복지부 노인정책관이 「노인수발보장제도 추진방안」을 발표하였다. 또한 동 제도는 지난해 7월 1차 시범사업이 시작되어 올해 3월이면 끝나고, 4월부터는 2차 시범사업이 시작될 예정이다.

Pre-harvest sprouting (PHS) refers to seed germination during ripening, due to loss of dormancy before harvest. As PHS in rice causes decrease in grain yield and quality, tolerance to PHS is an important trait of Japonica cultivars in Korea. It is important to investigate the related genes and environmental factors, because PHS is a quantitative trait. In this study, we examined PHS rates at three different times according to the cumulative daily mean temperature after heading (CTAH) for 5 rice cultivars released in Korea for 5 years from 2013 to 2017 to determine the effect of environmental factors on PHS. ABA content in ripening spikelets was analyzed to understand how it was related to PHS tolerance. PHS rate increased as CTAH increased from $800^{\circ}C$ to $1200^{\circ}C$. PHS rate was significantly different (p < 0.001) among the cultivars, showing Dasanbyeo, Jounbyeo, and Nampyeongbyeo to be PHS-tolerant, and Jopyeongbyeo and Gopumbyeo to be susceptible at all the CTAH of 800, 1000, and $1200^{\circ}C$. In 2015 and 2016, PHS rates were relatively higher, because of high temperature and frequent rainfall during the ripening period. In each cultivar, ABA content decreased as CTAH increased from $800^{\circ}C$ to $1200^{\circ}C$. However, there was no significant correlation between ABA content and PHS tolerance among the cultivars.

This study was purposed to examine the effect of the parental care burden on the labor force participation of the middle aged and older women. For this, this study used 2,125 samples aged from 50 to 70 years old that were extracted from 1st and 2nd wave of the Korean Retirement and Income Study(KReIS). In order to examine the causal relationship between two variables, Generalized Estimating Equation(GEE) and Multi-nominal Regression analysis were performed. The results showed that there was a positive effect of the parental care burden on the labor force participation of the middle aged and older women. However, this effect was limited only to the employment to the unpaid family workers. In addition, the effect was varied according to the level of caring time to the old parents. Based on that, several policy and practical implications were suggested.

The levels of polyamines were measured to investigate the alternative nitrogen metabolism during maturation and sprouting in rice. The rice plants (cv. Ansanbyeo) were cultivated in 20-year-old non-fertilized field. The flag leaves and spikes were collected weekly after the earing stage and the seeds were harvested daily after lodging. Free, bound, and conjugated polyamines were analyzed using reverse phase HPLC. Putrescine, spermidine, spermine, agmatine and tyramine were the major amines found in rice. The level of stress-induced amine, putrescine increased during the preharvest sprouting confirming that the process was a stress to the plants. With all other polyamines, tyramine in free form decreased in flag leaves and panicles during seed maturation. However, agmatine in bound form showed a noticeable increase about 8-fold during 6 weeks period of maturation after which it declined to the bottom level. Among the individual amines, tyramine and spermine in conjugated form showed a marked change during matutation and sprouting. Interestingly, the level of tyramine with all conjugated polyamine decreased in spikes during seed maturation and increased during preharvest sprouting implying that tyrosine decarboxyation and conjugation to phenolic acids may play a key role in preharvest sprouting. Spermine in conjugated form was synthesized only at the early earing stage in the level of $3.4mole\;g^{-1}$ fresh weight, and then decreased to the level of nmole during maturation. Thereafter, it dramatically increased to 2.8 mole during preharvest sprouting. In this study we found the tyramine is a major amine in rice, and it would play a critical role in N-assimilation during seed maturation and sprouting.

This excperiment was conducted to investigate relation on seed dormancy and vi-viparous germination with sucrose content, fatty acid composition and abscisic acid content of rice seeds. The following results were obtained by this experiment. Sucrose content of brown rice harvested at 20 and 40 days after heading was higher in Japonica and Sare type varieties than in Tongil and Indica type rices. Positive relationship was found be-tween sucrose content of brown rice and viviparous germination rate of rice varieties tested.J aponica and Sare type rice varieties showed low proportion of oleic acid and higher proportion of linoleic acid in brown rice harvested at 20 and 40 days after heading than Tongil and Indica rices tested. Viviparous germination was negatively correlated with the proportion oleic acid and positively with that of linoleic acid. Abscisic acid content in hull of rice seeds stored for 30 days at 25/15$^{\circ}C$ fluctuation temperature condition was decreased more rapidly than 4$^{\circ}C$, and Japonica varieties tested showed lower con-tent of abscisic acid in rice hull than Tongil and Indica varieties used.
