  • The monitoring of chemical dynamic changes in controlled horticultural lands is very important for agricultural sustainability. Field monitoring was performed to evaluate the soil chemical properties of 200 controlled horticultural soil samples in Gyeongnam province every 4 years from 2000 to 2012. Soil chemical properties such as pH, amount of organic matter, available phosphate, nitrate nitrogen, and exchangeable potassium, calcium, magnesium, and sodium were analyzed. The amount of exchangeable calcium and soil pH were significantly higher in 2012 than in 2000. In 2012, the frequency distribution for values of pH, organic matter, available phosphate, and exchangeable potassium, calcium, and magnesium that were within the optimum range was 16.0%, 22.5%, 11.5%, 3.5%, 2.5%, and 5.0%, respectively. Especially, available phosphate and exchangeable calcium were excess level with portions of 76.0% and 96.5%, respectively. These results indicated that a balanced management of soil chemical properties can reduce the amount of fertilizer applied for sustainable agriculture in controlled horticultural lands.

  • In connection with international commercial arbitration the need to seek interim relief is generally recognized. Interim reliefs address the requirements of a party for immediate and temporary protection of rights or property pending a decision on the merits by the arbitral tribunal. The most common forms of interim relief are attachments and injunctions. If the arbitral tribunal has not yet been appointed, an application for interim relief must usually be addressed to the local courts at the place of commercial arbitration. If the arbitral tribunal has been appointed, the application for interim relief is first made to the arbitral tribunal. Interim relief by the arbitral tribunal is in the form of a direction to the parties. Since the arbitral tribunal has no enforcement power, it may be necessary to have a arbitral tribunal's direction confirmed by a local court which can enforce its order. The New York Convention does not provide for interim reliefs. The question is whether Article II(3) of the New York Convention that the court "shall, at the request of one of the parties, refer the parties to arbitration" denies jurisdiction to courts to grant interim reliefs in international commercial arbitration. Some cases have indicated that the U. S. court have no power to grant interim relief. Other cases have indicated that the U. S. courts do have the power to grant interim relief. It is unlikely that a U. S. court will order interim relief in relation to an commercial arbitration in a foreign country. Article 26 of the UNCITRAL Arbitration Rules provides with respect to interim measures of protection. Section 1 of Article 26 of UNCITRAL Arbitration Rules provides that the arbitral tribunal may take any interim measures it deems necessary in respect of the subject matter of the dispute, including measures for the conservation of the goods forming the subject matter in dispute. This article gives the arbitral tribunal the broadest authority, not limited to safeguarding property. Article 17 of the UNCITRAL Model Law on International Commercial Arbitration provides that the arbitral tribunal may order any party to take such interim measure of protection as the arbitral tribunal may consider necessary in respect of the subject matter of the dispute. It may be noted that the article does not deal with enforcement of such measures. The International Chamber of Commerce Rules of Conciliation and Arbitration do not expressly empower the arbitral tribunal to grant interim reliefs. However, Article 8.5 of the ICC Rules of Conciliation and Arbitration provides that the parties shall be at liberty to apply to any competent judicial authority for interim measures. In conclusion, the power of the arbitral tribunal to provide interim reliefs is generally recognized in the arbitration rules of arbitral institutions. However, the arbitral tribunal's authority is limited by its lack of enforcement mechanisms. It is generally recognized that the local courts have power to grant interim reliefs in aid of an commercial arbitration. However, local courts are reluctant to grant interim reliefs if that decision requires an adjudication of issues within the special competence of the arbitral tribunal.

  • This study was carried out to elucidate the vertical characteristics of soil properties at six planted sites of land reclaimed from the sea, in Gwangyang Bay, Jeollanam-do Province, Korea. Based on the types of planting site, the chemical properties of the vertical soil layers varied. The vertical variation was great in the planting sites $Z_1\;and\;Z_2$, but less varied in the mounded planting sites $Z_3,\;Z_5,\;and\;Z_6$. Major reasons for the vertical variation in soil chemical properties included differences in the accumulation of organic matter, soil disturbance by heavy construction equipment, and heterogeneity of soil properties between soil horizons. As soil depths increased, soil salts varied. The electrical conductivity (ECe) increased in the lower areas of planting sites $Z_1\;and\;Z_2$, and the disturbed, saline planting site $Z_3$, but decreased in the lower areas of $Z_3,\;Z_5,\;and\;Z_6$. These tendencies did not coincided with exchange cation concentrations $(Na^+,\;K^+,\;Mg^{++},\;Ca^{++})$. Both total carbon (T-C) and total nitrogen (T-N) accumulated more in the lower areas of planting sites than in the higher areas, and levels were higher closer to the surface than in the soil depths. It is supposed that these tendencies are related to the accumulation of fallen leaves or other organic matter at the soil surface, and the soil chemicals then slowly move downward from the surface. Impediments to tree growth included soil hardiness, high soil salinity and exchangeable cation concentration, low soil moisture content, acidic or alkaline soil, low organic matter, heterogeneity of soil texture and establishment of soil stratification.

  • A preliminary study for energy efficient soil heating and contaminant removal using microwave was conducted. Soils sampled from floodplain were heated with microwave oven, and soil heating property and energy efficiency were compared to those heated with electrical furnace. In addition the effects of water, soil organic matter, and contaminated diesel on soil heating with microwave were investigated. Even though the electrical power consumption of electrical furnace and microwave oven were similar, temperature of soil heated with microwave oven was significantly higher than that of soil heated with electrical furnace. The increase of soil moisture content delays the raise of soil temperature during heating it with microwave oven. However, the effects of total petroleum hydrocarbon (TPH) (<10%) in contaminated soil matrix and small amount of soil organic matter (<5%) on the increase of soil temperature by microwave were not significant. Further studies for contaminated soils with different texture using pilot scale microwave reactor are required for application of this technique in the field.

  • In order to clarify the thermal and hygroscopic properties of indoor particulate matter (PM) in a semiclosed subway space, which is critically important for understanding of the distinctive particle formation processes as well as the assessment of their health effects, the size-resolved PMs (i.e., $PM_{2.5}$ and $PM_{10-2.5}$) were intensively collected on the platform of Miasageori station on the Seoul Subway Line-4. The elemental concentrations in soluble and insoluble fractions were determined by PIXE from the bulkily pretreated $PM_{2.5}$. The thermal and hygroscopic characteristics of individual particles were investigated via a combination of the unique pretreatment techniques (i.e., the high-temperature rapid thermal process and the water dialysis) and SEM-EDX analysis. Iron and calcium were unequaled in insoluble and soluble $PM_{2.5}$ fractions, respectively, with overwhelming concentration. The SEM-EDX's elemental net-counts for the pre- and post-pyrolyzed PMs newly suggest that magnesium and several elements (i.e., silica, aluminum, and calcium) may be readily involved in the newly generated subway fine PM by a high-temperature thermal processing when trains are breaking and starting. Through the water dialysis technique, it turned out that calcium has meaningful amount of water soluble fraction. Furthermore, the concentrations of the counter-ions associated with the calcium in subway $PM_{10-2.5}$ were theoretically estimated.

  • The long-term changes in the soil properties are closely related to the policy direction and the national program for the soil management. In this study, chemical properties of paddy soils in Jeonnam province were investigated at four-year interval since 1999 and the factors affecting change of chemical properties were analyzed in relation to the soil management policies. Chemical fertilizers supplied to Jeonnam province reduced by 57% in 2013 as compared with 1999, and the ratio of Jeonnam province to the national fertilizer supply gradually decreased to 14.1% in 2013 from 17.6% in 1999 due to national policies to reduce use of chemical fertilizers in the 2000s. In the chemical analysis of paddy soils in Jeonnam province, pH value tended to increase gradually within the optimal range. Available phosphate and exchangeable potassium content were always higher than the optimal range and showed no significant difference since 1999. Organic matter, exchangeable calcium and available silicate content were found to be lower than average content in the whole country as well optimal range for rice cultivation in 1999, but were higher than average content in the whole country and optimal range in 2011 because of faster rate of increase in Jeonnam province than the other region since the mid-2000s. The cause of increase in organic matter, exchangeable calcium and available silicate contents is considered to be the increased use of green manure crops and by-products fertilizer as an alternatives for conventional application of chemical fertilizers and soil amendment such as silicate fertilizer for agronomic control of the disease and insect pest in rice cultivation of environmentally-friendly agriculture.

  • These days utilization of copyright in daily life and economic activities is becoming more important than ever, and IT technology is developing day by day. Along with those fact, copyright infringement and dispute is naturally increasing. This thesis dealt with the 3 different issues of ADR on copyright. The First part, introduce ADR system that was performed by Korea Copyright Committee according to Copyright law. This paper evaluate the committee's efforts to provide resolution of copyright disputes via conciliation was effective. So it needs to be look over several countries' ADR, beside conventional judicial remedy. And Korea's copyright conciliation system which is successfully operating also introduced. Second, In many countries, including South Korea are take advantage of conciliation as the way to settle down the dispute over copyright. Furthermore, looked over if we can use arbitration as tool to settle dispute or not. Currently in Korea, patent dispute is handled by Industrial Property Dispute Conciliation Committee(The Invention Promotion Act Ch.5) and Layout-design Review and Mediation Committee(The Act on the Layout-designs of Semiconductor Integrated Circuits Art.29-34), but using performance of those two committee is still too low. In comparison, the copyright committee, a affiliation organization of the ministry of culture, sports and tourism has much more result in conciliation compare with patent dispute. Copyright disputes has arbitrability of it's subject-matter and many regulating organs are interested in it. (especially, binding of arbitral award and final resolution). Take advantage of both conciliation and arbitration could be good way to resolve copyright disputes. Third, the writer look at the proposal on the creation of Northeast Regional Center for Intellectual Property ADR. Because of the nature of copyright and rapid development of internet technology, international use of work become more frequent and accordingly infringement cases are increasing. The role of commercial arbitration regimes and institutions which has progressed significantly worldwide level, but which has only just begun in the intellectual property ADR area, leads also to a clash of often very different legal cultures and protection in a market economy. International cooperation in regional area with conflict interests becomes an important alternative. But it will depend on the building of regional institutions and mechanisms. The feasibility of this proposal and preconditions were examined. Establishment of new international organization requires a lot of time, cost and efforts. And risk of failure is much too high. Therefore factual, statistical review should be preceded. In addition, technical measures, such as on-line arbitration is necessary to review also. Furthermore in order to establish new organization, the relative law, legal environment, public sentiment and international compliance must be carefully considered with factual review about the needs and economic benefits of each country Yet on complex regulatory matters such as IP and ADR, a great deal of the potential benefits from international standards arises not from the international legal framework nor even the formal content of national legislation, but from the informed and effective use made of the possibilities within the system, including by policymakers and regulators.

  • Up until the mid-90s, the housing market of Korea has been supplier-oriented with the constant shortage of housing supply. But today, with the surplus of supply over demand and ever-increasing competitiveness in the housing market, understanding consumers needs have become one of the keys to successful business. Consumers overall living standard have increased and they are now looking for better living environment. As a matter of course, there have been much studies focusing on the evaluation factors and consumers preferences of the living environment, somewhat overlooking the asset value of a residential property. Consumers see their house in terms of both a living space and an asset. Therefore, it is these two values altogether that influences the buying decision process of consumers. This study seeks to stress on the importance of the fact that it is both the living environment and asset value of a house that are considered in the buyers valuation of residential property. And the study suggests that influencing factors of housing attributes in the decision-making process of buyers be sub-categorized into two broad groups, value as a living space and value as an asset. This is to serve both the researcher in the academic field and marketers for better understanding of consumers needs and influencing factors of buyers valuation of housings vis-a-vis market.

  • The CNTs are the most extensively studied material which are characterized by the complete property of matter, structure, and the large thermal conductivity (thermal conductivity of CNTs ~>2000W/mK vs. thermal conductivity of Aluminum ~> 204W/mK). Thus, they are successfully applied to the various fields. However, due to the strong agglomeration caused by the van der waal's force, their applications are limited. In the present study, a new method for CNTs dispersion was developed by using the mechanical dispersion, acid treatment, and then Cu was coated. This process produces CNTs/Cu nanocomposite powders, whereby the CNTs are homogeneously located within the Cu powders. The electrical properties of the CNTs/Cu nanocomposite were investigated.
