  • Background: The roots of Atractylodes macrocephala Koidzumi contain atractylone, which is used to suppress appetite and indigestion caused by gastrointestinal disturbance. The present study was conducted to investigate the effect of several organic compost on the growth and root yield of A. macrocephala with organic fertilizer. Methods and Results: When organic fertilizer was applied basally, the average yield of 10 a was 184.6 kg in the HA (Hwanggeumjidae, organic material mix), 171.3 kg in the GG (Gyunbaeyangchegreen, bacterial cuture filtrate) and 175.0 kg in the CF (Customary fertilization, control) each other in practice of CF had no statistical significance. Atractylenolide I was significantly greater in the HA (0.036%) than the GG (0.034%) or CF (0.023%). With regard to the amount of organic fertilzer, 10 a yield was the most common of 203.0 kg at 2.0 times of the organic 1 (HA), conventional fertilization of 134.0 kg and 173.0 kg of no application was a statistically significant. Organic fertilizer 1 was 1.5 to 2.0 times, organic fertilizer was 2 to 1.5 times that were most suitable. Conclusions: The results of the present study indicated that HA and GG are the most suitable for the organic cultivation of A. macrocephala. The content of atractylone I was highest under the HA treatment and lowest under the CU (Chamjoa, oil cake), TG (Totogreen, plant oil cake) and HG (Heuksalgreen, Castor oil cake) treatment.

  • For the land-cover classification we have usually used imagery of the optical sensors only. But currently a number of the satellite with various sensors are operating and the availability of using the data acquired from them are increasing. SAR sensors, in particular, can produce additional informations on the land-cover which has not been available from optical sensors. On this study, I have applied the SAR Image to the SPOT XS image in the classification procedures, and analysed the classified results. In this procedure I have extracted texture informations from SAR intensity images, then applied both intensity and texture informations. From the accuracy analysis, overall accuracy are increased slightly when the SAR texture was applied. In case of the Built-up class the results showed higher accuracy than those of when only the SPOT XS image was used. From this result I can show that overall accuracy was increased slightly but the spatial distribution of classes was visibly improved.

  • Since the advent of high resolution satellite image, possibilities of applying various human interpretation mechanism to these images have increased. Also many studies about these possibilities in many fields such as computer vision, pattern recognition, artificial intellegence and remote sensing have been done. In this field of these studies, texture is defined as a kind of quantity related to spatial distribution of brightness and tone and also plays an important role for interpretation of images. Especially, methods of obtaining texture by statistical model have been studied intensively. Among these methods, texture measurement method based on cooccurrence matrix is highly estimated because it is easy to calculate texture features compared with other methods. In addition, these results in high classification accuracy when this is applied to satellite images and aerial photos. But in the existing studies using cooccurrence matrix, features have been chosen arbitrarily without considering feature variation. And not enough studies have been implemented for appropriate resolution selection in which cooccurrence matrix can extract texture. Therefore, this study reviews the concept of cooccurrence matrix as a texture measurement method, evaluates usefulness of several features obtained from cooccurrence matrix, and proposes appropriate resolution by investigating variance trend of several features.

  • This paper purposes to examine the setting aside and the refusal of enforcement of arbitral awards and their implications for practitioners. The aim of challenging an award before a national court at the seat, or place, of arbitration is to have it modified in some way by the relevant court, or more usually, to have that court declare that the award is to be disregarded (i.e. "annulled" or "set aside") in whole or in part. If an award is set aside or annulled by the relevant court, it will usually be treated as invalid and accordingly unenforceable, not only by the courts of the seat of arbitration but also by national courts elsewhere. This is because, under both the 1958 New York Convention and the UNCITRAL Model Law, the competent court may refuse to grant recognition and enforcement of an award that has been "set aside" by a court of the seat of arbitration. The New York Convention set out various grounds for refusal of recognition and enforcement of an arbitration award. The provisions of the Model Law governing recognition, enforcement or setting-aside of awards are almost identical to those set out in the Convention. Especially, the New York Convention and the Model Law state that an arbitral award may be refused and set aside if a national court of the place of arbitration finds that the award is in conflict with the public policy of its own country. Each state has its own concept of what is required by its "public policy". It is possible to envisage, for example, a dispute over the division of gaming profits from a casino. In many states, the underlying transaction that led to the award would be regarded as a normal commercial transaction and the award would be regarded as valid. Indeed, it is a consistent theme to be found in the legislation and judical decision of many countries. If a workable definition of "international public policy" could be found, it would provide an effective way of preventing an award in an international arbitration from being set aside and refusal for purely domestic policy consideration.

  • In implementing a computerized virtual training system, the auditory element is responsible for the human cognitive ability following visual elements. Especially, the improvement of hearing ability is closely related to the performance of the training, and it contributes to improvement of the training effect. In this paper, we propose a sound system that is necessary for constructing such a virtual training system as a test system that can use a sound source using a head related transfer function (HRTF). Functional and auditory tests were performed to evaluate system performance.

  • Spectral pattern recognition techniques are most used in classification of remotely sensed data. Yet, in any real image, adjacent pixels are related, because imaging sensors acquire significant portions of energy from adjacent pixels. And, with the continued improvement in the spatial resolution of remote sensing systems, another spatial pattern recognition approach is must considered. In this study, we aim to show the potentiality of spatial classification methods through comparing the accuracies of spectral classification methods and those of spectral classification methods. By the comparisons between the two methods, classification accuracies of 6 different spatial classification methods are higher than that of spectral classification method by 2-6% or so. Additionally, we can show it statistically through the classification experiments with different band combinations.

  • Large-scale and complex disasters have frequently occurred all over the world recently, and they are repeated every year. Accordingly, the need for the systematic management and utilization of raw-data and processing information in the past has increased. For this purpose, this study proposed a construction strategy for disaster and safety record information resources archives based on automatic acquisition, which can be used as a hub for disaster and safety information. Based on local and foreign case studies, several consideration factors for building the archives are determined. Finally, this study proposed four steps for constructing the archives. These are as follows: 1) complete enumeration survey of the disaster and safety record information resources, 2) automatic acquisition possibility study, 3) selection of the resources for preservation, and 4) automatic acquisition of metadata. The construction of the archives proposed in this study will facilitate integrated management, sharing, and use of scattered information resources on disaster and safety.
