This paper discusses life expectancy differentials of beneficiaries of national pension old-age benefit and benefit-cost analysis in Korea. These results are useful indicators for the assessment of retirement income security of beneficiaries and old-age benefits. This paper analyzes benefit-cost ratio, internal rate of return and generation transfer amount, using life tables by lifetime incomes. The result of the actuarial analysis for male life expectancy is approximately 21.69 to 24.63 years. The result of the actuarial analysis for female life expectancy is approximately 27.63 to 29.81 years. The result of the actuarial analysis of low income level is that the benefit-cost ratio is lower approximately 2.68 to 4.83%, the internal rate of return lower approximately 0.00 to 0.74%, the generation transfer amount lower approximately 3.00 to 5.74%, than total income level. The result of the actuarial analysis of high income level is that the benefit-cost ratio is higher approximately 2.07 to 4.98%, the internal rate of return higher approximately 0.03 to 1.73%, the generation transfer amount higher approximately 2.53 to 9.68%, than the total income level. The results by income varies due to the effect of income redistribution and life expectancy on the national pension.

While the recovery of local construction industry is picking up steam, and the number of the employed in the construction industry is on the increase, workforce supply is out of balance in its quality as well as quantity, and with economic crisis facing the country, construction and recruitment methods are in transition. In addition, rising demand in skilled workforce and a workforce in short supply have expedited wage rises and have brought broad effects on construction including productivity and construction time. Such imbalance in construction workforce supply also causes various structural changes by category. This research compares and analyzes data on annual wages of construction workforce, analyzes the state of construction workforce supply, understands recruitment structure in accordance with workforce supply conditions, and looks over characteristic changes in recruitment structure. With reflections drawn from these, this paper suggests responsive measures to future construction circumstances - changes to wages of construction workforce - as well as prospects of future construction workforce supply and measures designed for stable medium and long-term workforce supply.

합성고무의 주원료인 Butadiene-Naphtha-원유에 대해서는 1973년의 석유위기 이후, 작년말 이란 혁명을 계기로 재차 어려운 국면을 맞이하게 되었다. 그 동안 OPEC의 원유가격의 대폭인상 결정, 동경 Summit에서의 선진국들의 석유 수입제한목표의 설정 등 세계경제의 동향에 큰 영향을 미치는 결정 등이 계속 나와 석유 및 석유화학제품의 수급구조도 크게 변화될 것으로 보인다. 그 과정에 있어서, 고무원료의 장기수급 동향을 정확히 확정하기에는 매우 어려운 일이나 합성고무와 천연고무의 현상태를 분석하여 앞으로의 전망에 대해서 각종자료를 바탕으로 검토해보고자 한다. <편집자주>
