The development paradigm based on modernization theory and economic growth since the WWII reached an impasse in the 1980s. As an alternative, the new perspective on development as a whole social development beyond economic growth has emerged, and culture as an important method for as well as a approach to development has been emphasized. Post-development theories destruct the European development concept and suggest alternative developments emphasizing culture restoration, endogenous growth, diversity, and neopopulist developments movement emphasize community, gender, ownership, and participation. International Organizations such as UNESCO have also examined and developed the relations between culture and development. Although different from that of the past development paradigm, acknowledging other cultures, however, this elaborated concept of culture has some limitations and need to be reconceptualized through applying the geographical concept of 'relational place.' The concept of relational place can help recognize internal diversity within culture and community and link them to a broader economic and political contexts.

본고(本稿)에서는 최근 미국연방준비은행(美國聯邦準備銀行)의 Hallman Porter Small이 개발한 인플레추정방법, 즉 화폐수량식에 장기균형유통속도(長期均衡流通速度)($V^*$), 잠재생산력(潛在生産力)($Q^*$), 장기균형기준물가(長期均衡基準物價)(P*)등의 개념을 적용하여 인플레식(式)을 추정하는 방법을 우리나라에 적용하여 보았다. 이를 위해 $V^*$는 인플레의 변동에 의해 구조적(構造的)으로 변동(變動)될 수 있다는 점과 $Q^*$는 고용(雇傭)뿐 아니라 투자의 함수라고 가정하고 자본스톡 및 $Q^*$를 내생적으로 추정하는 등으로 $V^*$, $Q^*$의 개념을 재정립하였다. 추정결과(推定結果)에 의하면 87년초 이후부터 실질생산(實質生産) 잠재(潛在)GNP를 초과하게 되었으며 통화공급(通貨供給) 역시 확대되어 $P^*$가 P를 넘어서는 현상, 즉 물가상승압력(物價上昇壓力)이 누적되어 왔으며, 이에 따른 물가불안이 해소되기에는 정책대응여하에 따라 상당한 기간이 소요될 수도 있을 것으로 냐타났다. 즉, 시뮬레이션결과 종합해 보면 물가상승압력(物價上昇壓力)의 완화를 위해서는 투자진작을 통한 잠재생산력(潛在生産力)의 확충과 아울러 긴축기조(緊縮基調)의 유지라는 일견(一見) 상반(相反)되는 정책기조(政策基調)를 동시에 추진해 나가야 할 것으로 나타났다. 현재의 경기국면에 대한 대응책으로는 통화공급(通貨供給)을 확대시키는 단순한 총량적 정책보다는 긴축기조(緊縮基調)를 유지하면서도 통화(通貨)의 신축적(伸縮的)인 공급이 투자(投資) 고용(雇傭) 등의 생산부문(生産部門)으로 원활히 흐를 수 있도록 하는 동시에 금융구조(金融構造) 경제구조(經濟構造)를 개선해 나가는 미시적이고도 포괄적인 정책이 요구된다 하겠다.

Ideas do not become exhausted, and there are no diminishing returns in the creation of knowledge. Nonetheless, growth ultimately ceases in this simplest model of endogeneous innovation. The reasons are similar to those that are discussed in the context of the neoclassical model of capital accumulation. Even if the resource cost of creating new goods does not rise, the economic return to invention may decline as the number of available products increases. When the rate of return to R&D falls to the level of the discount rate, private agents cease to be willing to defer consumption in order to invest in product development. But, if we treat knowledge capital as a public capital considering of its non-appropriable benefits, economic growth can be sustained in the economy. Romer(1986) has pointed out that growth might be sustainable if the accumulation of knowledge is not subject to long-run diminishing returns. Actually Romer assumed diminishing returns in the production of private knowledge from available resources, but increasing returns in the production of output from labor and total (public and private) knowledge. His condition for the sustainability of long-run growth amounts to an assumption that the diminishing returns in the former activity do not outweigh the increasing returns in the latter. The Johansen(1988) cointegration test method is used for finding long-run equilibrium relationship between R&D input and the product innovation. Test results indicate the existence of cointegrating equation between each pair of regression variables including dependent variable in the knowledge production function. And, the signs of cointegrating vectors are well accord to the prediction of sustainable growth. In the empirical analysis, from all cases of the form for the knowledge production function, we could not reject the null hypothesis that R&D spillover effect is significant($H_{0}:\;{\gamma}=1$). In summary, we showed that considering goodness of fit of regression model, we can see that the empirical evidence is strongly in favor of the character of knowledge as the public knowledge capital. So, we can expect that by product innovation, economic growth can be sustained in the Korean economy.

본(本) 거시경제모형(巨視經濟模型)은 "케인즈"적인 소득지출모형(所得支出模型)으로서, 최근 개방화 및 자율화추세에 따라 크게 변모한 경제구조하에서 예측의 정확도를 높이고 대내외여건(對內外與件) 변화(變化)에 기인한 제반 영향을 보다 명확하게 분석하기 위해서 작성되었다. 모형(模型)의 구조(構造)는 6개 부문, 162개의 방정식으로 구성되어 있으며, 70년대와 80년대의 구조변화(構造變化)를 고려하여 1982년부터 1991년까지를 추정대상 기간으로 삼았다. 기존의 KDI 분기모형과 비교할 때 본(本) 개정모형(改定模型)의 가장 두드러진 특징은 총량변수를 항목별로 세분하여 대내외여건 변화시 경제에 마치는 영향을 기존의 총량수준보다 한 단계 더 세분화된 수준에서 파악하고자 한 점이다. 또한 각종 가격변수들의 시장조절기능(市場調節機能)을 반영하기 위해서 금리(金利), 임금(賃金), 환율(換率) 등을 내생화(內生化)하였고, 총통화(總通貨)와 장기자본수지(長期資本收支) 등도 모형내에서 결정되도록 하였다. 역사적(歷史的) 시뮬레이션의 결과, 주요 내생변수의 평균자승근퍼센트오차가 5% 내외의 양호한 수준을 나타냄으로써 본(本) 모형(模型)이 80년대의 구조변화(構造變化)를 적절히 반영하고 있다고 볼 수 있다. 정책(政策)시뮬레이션은 원유 및 원자재수입가격과 같은 해외여건(海外與件) 변화(變化)와, 기타건설(其他建設), 정부소비지출(政府消費支出), 국내민간신용(國內民間信用)의 확대와 같은 정책변화(政策變化)의 두 부문으로 나누어 시행하였다. 원유 및 원자재가격의 상승은 우리 경제에 부(負)의 공급충격(供給衝擊)으로 작용함으로써 성장을 둔화시키고 물가를 상승시켰으며, SOC 투자를 포함한 기타건설(其他建設)의 증가(增加), 정부소비지출(政府消費支出),의 확대(擴大), 민간신용(民間信用)의 증가(增加)는 모두 단기적으로 경기부양의 효과는 있으나 장기적으로 물가를 더욱 상승시키는 것으로 나타나 물가(物價)와 성장(成長)이 서로 상충관계에 있는 것으로 파악되었다.

This paper develops a simple theoretical model that is consistent with the empirical evidence of an inverted U-shpated relationship between pollution and per capita income, which is so-called environmental Kuznets curve in this literature. Also, by incorporating the issue of environmental externality into an endogenous growth model, I investigate the circumstances under which growth can be sustained with the optimal control of pollution, and hence the sustainable development can be achieved. In order to study the problem of implementing the social optimum in a market economy, I examine the optimality of three different kinds of environmental policy instruments; pollution tax, pollution-permit trading system (pollution voucher), and direct regulation. This paper shows that the optimum can be implemented with a pollution tax or with a voucher system. Also, it is shown that the socially optimal rate of pollution tax should increase proportionally to the growth rate of consumption.

This study has developed Computable General Equilibrium (CGE) model reflecting endogenous growth economic theory, with the aim of analyzing double dividend hypothesis. This study analyzes possibility of economic growth and environmental improvement at the same time when government recycles the revenue of carbon tax to reduce existed taxes such as consumption tax, labor income tax, corporate tax. It also assesses the case of subsidy on R&D investment of renewable energy. With new and renewable generation technology adopted and disseminated, GDP loss would be lessened to a great degree. Tax recycling would provide economic gain by reducing distortion existed in the existing fiscal structure. The magnitude of economic gains from carbon tax recycling is biggest for recycling into corporate tax, and labor income tax, and then consumption tax in this order. It is also shown that double dividend effects occur in dynamic terms when government uses a carbon tax revenue to subsidize on R&D investment. At the end of the analysis period, emissions reduction would not result in GDP loss but in GDP gain. In particular, recycling into R&D increase would produce the largest and fastest GDP gain. Thus, implementing emissions reduction target would require careful consideration of economic effects by various policy instrument, including carbon tax.

Purpose: This study tested a model of hospice volunteer's motivations and outcomes to encourage more volunteer workers to participate in hospice care. Methods: This included 200 volunteers who attended the Autumn Conference in 2007 and 132 volunteers from five hospice organizations. Results: Volunteers' existential well-being affected an endogenous variable of volunteers' participation in volunteer activities. The durability of volunteer activity was affected by value motivation, the level of participation in volunteer activities and the level of job satisfaction. For volunteers' job satisfaction level, valid endogenous variables included existential well-being, social motivation, understanding motivation and value motivation. The durability of volunteer activities was indirectly affected through three different paths. Volunteers' existential well-being determined the level of their participation in volunteer activities, which in turn affected the durability of such activities. Social motivation influenced volunteers' job satisfaction, and then the durability of volunteer activities. Volunteers' understanding of motivation also influenced their job satisfaction, and then the durability of volunteer activities. Conclusion: Based on these results, this study proposes that the durability of volunteers activities could be improved by developing a program to improve volunteers' well-being and by providing volunteers with education on altruistic values, encouraging them to seek intellectual growth, and advocating them to continue volunteer activities based on close relationships with other volunteers.

This paper aims at examining the role of university, industry and government, which constitute the triple-helix innovation system in hi-tech cluster, based on the case of the Research Triangle Park, North Carolina, USA. Firstly, the state government has played a catalytic role by building the horizontal governance of triple-helix actors. By doing so, the state government has made it possible for not only growing but also transforming the RTP as an high-tech cluster. Secondly, universities in the triangle area have played to some extent a limited role in sustaining the evolution of cluster. Thirdly, the RTP has long been dominated by a small group of large firms. However, the situation has been changed since 1990s, because new start-ups from universities and local large firms and the technology transfer activities between universities and firms have been increased in the RTP and its surrounding area. Finally, it argues that the continuous evolution of the RTP has been to some or large extent influenced by the transition from the exogenous development model to the endogenous development model.

Morphological observation of roots and molecular technique were used to investigate the symbiotic relationships between arbuscular mycorrhizal (AM) fungi and ginseng roots. Korean ginseng, Panax ginseng, was collected from 8 sites in Korea. Colonization pattern of AM fungi in ginseng roots was determined as an Arum type under light microscopes. Nested PCR using AM fungal specific primers was employed to amplify a partial region on 18s rDNA of AM fungi from the root extracted mixed DNA. The amplified DNA was cloned and analyzed by random fragment length polymorphism (RFLP) with restriction enzymes, AluI, HinfI and AsuC21. One from each RFLP pattern was selected for sequencing. A total 16 clones were sequenced and identified as 2 species of AM fungi; Paraglomus brasilianum and Glomus spurcum. Paramglomus brasilianum was found from most of the ginseng roots, in this syudy suggesting that this species of AM fungi could have specific relationship with the ginseng root. Possible roles of AM fungal species in ginseng roots are discussed.

Persisent circadian rhythms in carbon assimilation, stomatal conductance and soluble carbohydrate concentration were investigated during grain filling period in rice plant transferred from a natural photoperiod to constant conditions. A weak rhythm in photosynthesis, measured as carbon assimilation, and stomatal opening, as conductance to water vapor, with a period of approximately 24-hours, occurred under constant condition. Carbon assimilation and stomatal conductance reached maximum values near noon and minimum values near midnight during the early stage (until 72-hour) after transferring to constant condition, and then the amplitude and phase were changed slowly, the rhythms with little damping, reaching maximum values near midnight and minimum values near noon during 96~120-hours after transferring. However, photosynthesis in plants grown for 14days after anthesis under constant moderate light(day and night) did not oscillated in constant condition unlike plants grown under a cycle of light and darkness. These phenomenon was observed in soluble carbohydrate concentration in flag leaves as well. Evidences from several approaches indicate that endogenous rhythms of $CO_2$ assimilation, stomatal conductance and soluble carbohydrate concentration are closely couped with each other and particularly important to plants, which depend on the natural day-night cycle as a external signal.
