  • The food self-sufficiency rate of agricultural products in Korea, excluding rice, is around 20%, and the government is promoting various policies including a Multiple-Purpose Utilization of Paddy Fields project, to increase the self-sufficiency rate of major grains. The project for Multiple-Purpose Utilization of Paddy Fields is being promoted as a part of a program to create farmland infrastructure to facilitate the cultivation of crops other than rice in rice paddies, and pilot projects were started in four regions in 2020. The purpose of this study is to analyze the economic effects of the pilot project for Multiple-Purpose Utilization of Paddy Fields, and to propose policies to increase the effectiveness of the project. In order to analyze the economic effect, we estimated the change in farm income generated by switching from rice to other crops, and measured the effect of welfare change using the Equilibrium Displacement Model (EDM). As a result of the analysis, social welfare is expected to increase when the pilot project for Multiple-Purpose Utilization of Paddy Fields is implemented, and the income of the beneficiary farmers is also expected to improve compared to that of single-cropping when double-cropping is implemented. However, it was found that the economic feasibility of the project differs depending on the crops converted. Juksan-myeon, Gimje-si, which is an area where soybean production was successful, was analyzed from the viewpoint of increasing the economic feasibility of the pilot project. Their success factors were analyzed into four major factors: infrastructure, farming methods, education, and collaboration with local agricultural organizations. If such a success story can be utilized in the future project implementation process, it can contribute to the improvement of farm household income and national economic welfare.

  • Cyclosporin A (CsA) plays an important role in clinical medicine and basic biology as an immunosuppressant and a mitochondrial permeability blocker, respectively. It was reported that CsA has a protective role by preventing apoptosis and promoting the proliferation in severed neurons. However, the molecular mechanisms for CsA-induced neuronal cell proliferation are unclear. In this study, we examined the mechanisms underlying the CsA-induced proliferation of PC12 cells. CsA increased the viability of PC12 cells in a dose(over 0.110μM)-and time-dependent manner. The level of ROS generation was decreased in the CsA-treated PC12 cells. Expression of Bcl-2, an antiapoptotic molecule that inhibits the release of cytochrome c from the mitochondria into the cytosol, was upregulated, whereas Bax, a proapototic molecule, was not changed in the CsA-treated PC12 cells. CsA downregulated the mRNA expression of VDAC 1 and VDAC 3, but VDAC 2 was not changed in the CsA-treated PC12 cells. The level of cytosolic cytochrome c released from the mitochondria and the caspase-3 activity were attenuated in the CsA-treated PC12 cells. These results suggest that the mitochondria-mediated apoptotic signal and Bcl-2 family may play an important role in CsA-induced proliferation in PC12 cells.

  • The National Land Census Project aims to survey the national land regularly to resolve the land category disagreement and reflect the actual land use. The objective of this study is to investigate whether not only the National Land Census Project but also related land and housing surveys bring about the improvement of social welfare in light of the invested budget, and to measure the project feasibility. The potential benefit after the National Land Census Project is not traded in the market. To determine the economic value of this potential benefit, the Contingent Valuation Method was used. This study utilized the single-bounded and double-bounded dichotomous choice models simultaneously to estimate the project feasibility of the cadastral system improvement. According to this study, cost-benefit ratio of the project was estimated larger than 1, which means that social benefits are larger than social costs.

  • Hemangioma and vascular malformation are the most common benign tumors that are caused by congenitally or traumatic events. Theses tumors represent approximately 1/3~1/4 of all hemangiomas and vascular malformations in the head and neck. There are many forms of treatment for hemangioma and vascular malformation including closed observation, surgery, radiotherapy, laser therapy, steroid therapy, compression, embolization, and sclerotherapy. Ethanolamine oleate is an unsaturated fatty acid salt that has been used as a sclerosing agent because of its excellent thrombosing properties. This paper presents 1 case of intraoral multiple venous malformations treatment with 1.25% ethanolamine oleate (3.6~9.6 mg dose) intralesionally injected for 6 to 14 weeks over 2 week intervals. After the sclerotherapy, lesions almost completely disappeared without side effects. In conclusion, sclerotherapy using ethanolamine oleate is very effective against venous malformations, and sufficiently provides alternative support for surgical and other methods.

  • This study aims to identify the relationship between termite-damaged cultural heritage sites and the 'Forest Tending Project' based on a comprehensive survey of the status of damage caused by termites and of the Forest Tending Project. It was observed that the Forest Tending Project started in 2004 as a five-year policy project covering over 59% of the nation's forests, which showed the maximum value in 2009 and then gradually decreased. Since then, increased damage to national cultural heritage sites by termites has been confirmed and counter measures have been expanded since 2012. Also, as a result of the National Research Institute of Cultural Heritage surveying the status of termite damage in national cultural heritage sites over these six years, it was identified that about 98% of investigated cultural heritage sites were damaged by termites, about 78% of them were adjacent to forests, and that all 46 national cultural heritage sites which had been included in the 2008 Forest Fire Prevention Cultural Heritage Afforestation Project were damaged by termites. Therefore, it is claimed that the number of termite-damaged cultural heritage sites has increased after an extensive Forest Tending Project was applied on a national scale, and it seems that all cultural heritage areas close to forests are particularly subject to termite-damage due to the number of tree stumps and lumber byproducts which can serve as habitats for the pests.

  • Floats are used by the parties involved in a construction project. The owner may use float by changing order(s) or by executing risk avoidance plan; the contractor may use it for leveling resources or substituting activities' construction methods to reduce costs. Floats are accepted either just as by-product obtained by critical path method(CPM) scheduling or as asset having significant value. Succinctly, existing studies involved in float value does not consider its' changes on project time domain. It is important to identify float ownership and to quantify its' corresponding values. This paper presents a method that quantifies float value of money that changes over project execution. The method which accurately computes the monetary value of float may contributes to resolve conflicts relative to float ownership and/or delay issues among project participants. It compares the difference between the monetary value of total float - on non-critical path in each and every schedule update. It makes use of critical path method (CPM) and commercial software with which practitioners are already familiar.
