  • Our society has been dominated by the Dilemma Theory that rational individuals cannot get out of the 'Tragedy of the Commons' without helps from state or market. However, many empirical researches have discovered cases that common pool resources could be managed by cooperative methods of community. Based on the possibility of managing common pool resources by residents' cooperation/solidarity revealed by the recent case researches, this study aims to seek for the theoretical basis to prove it. Generally, public policies are carried forward based on the theoretical basis of the relevant social issues. The objective of this study is to suggest the new direction of policies related to domestic common resources through the researches on community's role in managing local common pool resources represented as "scenic spot". For this, it aims to reveal the influence of community activity on behavioral intention of local common pool resources, by drawing/quantitatively measuring measurement items of local residents' community activity on top of attitude, norms, and behavioral control suggested by the existing Theory of Planned Behavior. The results of this study are as follows; 4 factors such as attitude toward behavior, subjective norm, perceived behavior control, and community activity were all factors that influenced intention to manage.

  • This paper present a performance evaluation method for Timed Place Petri Nets modeled by Live-and-Bounded Circuits (LB-circuits) through a bottom-up approach. The method can handle the case for the nets having common resources(CR). The target system is divided into the sub-systems by disconnecting the common Transition-Transition-Path(TTP) or Place-Place-Path (PPP) between sub-systems. The common PPP pattern is classified into Parallel Common Resource (PCR) and Sequential Common Resource (SCR) in detail for handling common resources. We evaluate the performance of each divided sub-system, and calculate the sub-systems affect on the performance of the whole system. The facts are generalized as a theorem. The developed theorem are applied into the performance evaluation of an automated assembly system shown in an example. All the results are verified by simulation.

  • To elucidate genetic diversity of common reed in Korea, we collected a total of 674 common reed plants from 27 regions in South Korea. Hierarchical clustering using 7 morphological traits divided the 27 common reed populations into 7 groups. Random amplified polymorphic DNA (RAPD) results identified three distinct groups of common reed. Common reed accessions in group I mostly inhabit coastal areas. Group II includes reeds mostly collected from inland areas. Group III consists of common reed accessions collected from inland and coastal areas, suggesting that this group might contain hybrids. In summary, we suggest that parapatric speciation might be an important factor in the genetic diversity of common reed and geographical speciation of common reed that might be also affected by environmental gradients.

  • On the basis of sustainable long-term water resources planning, the development of ground water resources should be interlocked with the surface water development In considering the intertemporal equity, overpumping of groundwater may diminish or eliminate the groundwater resources stock of post-generations. Regulatory landuse zoning for groundwater resources recharge area is indispensable measures to prevent groundwater pollution. Adequate treatment of polluted water from various sources such as municipal sewage, industrial wastewater, landfill site leachate, and abandoned boring wells, is also necessary for groundwater protection. To preserve groundwater resources as common property goods, groundwater use tax should be imposed upon the large scale groundwater use. Finally, the establishment of groundwater development license system is recommended to achieve the social optimal production and to avoid external diseconomy.

  • We studied the antioxidant, the anti-inflammatory, antithrombotic, and antiobesity activities of seven different kinds of edible plants. 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ABTS radical scavenging activities were determined as a measurement of antioxidant activity. NO production inhibition by the macrophage cell line (Raw 264.7) treated with lipopolysaccharide (LPS) was carried out to assess anti-inflammatory activity. Thrombin inhibitory activity was measured for its antithrombotic function and inhibition of 3T3-L1 cell differentiation was evaluated as a measurement of antiobesity activity. Total phenolic components and total flavonoid contents were measured to determine functional materials in medicinal plants. Common sage, Japanese lady bell, and hairy agrimony showed high antioxidant activity ($IC_{50}$) of less than $100{\mu}g/mL$. All samples used in this study showed anti-inflammatory activity. Common sage, hairy agrimony, and hooker chives showed antithrombotic effects. Hairy agrimony showed the highest antithrombotic effect (98.1%). Common sage, Japanese lady belly, hairy agrimony, and hooker chives showed reduced 3T3-L1 cell differentiation and hooker chives strongly inhibited lipid accumulation in the cells compared to other medicinal plants. Common sage and hairy agrimony contained more than 1 mg GAE/g of phenolic compounds and more than 1 mg CE/g of flavonoids. Functional activities were different by plant part and extraction method from each sample. These results suggest that common sage, Japanese lady belly, hairy agrimony, and hooker chives may be used as healthy food sources with antioxidant, anti-inflammatory, antithrombotic, and antiobesity activities, and appropriate extracting methods from each plant need to be developed.

  • The behavior patterns of common octopus, Octopus minor to a cylindric trap were examined in the water tank using a video camera in order to know entering mechanism to the trap and to improve it. Fishing efficiency by 2 kinds of traps(A: 3 entrances, B: 2 entrances) was investigated in the coastal area of Deugryang Bay from May to July, 2005. Common octopus tends to approach by swimming more than walking towards trap. When they approached to the trap, they showed much more behaviors that sate at the around than upper part of it. Approaching behaviors of common octopus was more vigorous at nighttime than daytime on the trap, they showed the most vigorous action between 2 am and 4 am of the day. The rate of staying 30 seconds over around the trap was 41.5% in the nighttime. CPUE(g/trap) of common octopus caught by A type trap was 21.4% higher than the B type trap but there was no difference on the significance level of 5% by the ANOVA. Catch rate of common octopus and by-catch species caught by the A type trap were 97.2%, three and 98.7%, two for B type trap, respectively.

  • 디지털 정보환경의 변화에 따라 이용자의 서비스요구는 다양해지고 복잡해졌다. 본 논문에서는 미국 대학 도서관을 중심으로 도입 확산되고 있는 Information Commons의 정의, 개념, 유형 등에 대한 이론적 연구를 진행하였다. Information Commons는 단순한 도서관 시설이나 공간이 아니라 디지털 정보환경에서 비롯된 이용자의 다양한 정보요구를 이행하기 위한 협력적 서비스의 제공, 인적자원의 제휴, 물리적인 공간 및 시설의 재정의가 수반된 통합적 서비스 모델이라고 할 수 있다. Information Commons의 성공적인 도입 및 구축을 위해서는 디지털 정보자원에 대한 접근, 유기적이거나 연속적인 서비스의 제공, 이용자 중심의 서비스를 제공하기 위한 자원의 통합이 선행되어야 한다.

  • Many research results have indicated that many kinds of useful ingredients are rich in buckwheat, which have high nutritional values and medicinal properties, so, buckwheat has been cultivated around Asia and Europe. In this paper, genetic diversity of common and tartary buckwheat germplasms were studied based on morphological and molecular markers in order to provide useful information for conservation and utilization of buckwheat genetic resources. The length, width, thick, value and weight of the seed of the common and tartary buckwheat were measured and analyzed by the statistics methods. The result has shown that there are morphological variation both in common buckwheat and tartary buckwheat seeds collected from different regions. It also has shown that the morphological variation of tartary seeds was significantly correlated to geographical regions. The nuclear ribosomal internal transcribed spacers (ITS) of the tartary buckwheat collected from different countries were cloned, sequenced and statistically analyzed. The data showed that ITS sequences were informative to analyze the phylogeny of the tartary buckwheat and the data also showed that the genetic distances varied among different tartary buckwheat seeds collected from different countries.
