In recent years, the scale of damage from disasters such as earthquakes and large-scale fires and floods that are occurring in Korea is increasing. Accordingly, interest in urban disaster prevention that combines living infrastructure such as roads and parks is boosting, and it is urgent to prepare measures to reduce the damage scale of local cities. The purpose of this study is to derive implications for disaster prevention measures in areas where disaster prevention safety of local cities is weak through examples of disaster prevention safety of local cities in case of disaster. To this end, this study analyzed the regional characteristics, current status, and disaster prevention problems of regional cities in Japan, and selected disaster-vulnerable areas, and considered the distance relationship between disaster prevention bases through road network analysis. In addition, road closure simulation using ArcGIS Network Analyst was conducted to analyze disaster prevention safety in the area. As a result, the situation of the village which has a high possibility of isolation by natural disasters was grasped in advance. Through this, the suburbs confirmed the necessity of supplementing the disaster prevention function through transportation maintenance such as forest roads, and it was found that the city needs to prepare a risk management system. Furthermore, this study suggests the need for research on areas with a high possibility of isolation, especially in areas where disaster prevention functions are weak in local cities in case of disaster, and shows countermeasures for disaster prevention measures and resident education.

Objective : Korean medicine treatment method is noted as alternative in treating traffic accidents(TA) victims recently. The main purpose of this research is to make a survey of the effective way of the Korean medicine treatment about TA victims. Methods : In following research, 389 cases of traffic victims who hospitalized in the Youngsaeng Korean Medicine Hospital & Youngsaeng Clinic from March 1, 2001 to November 30, 2001 were surveyed. The research is focused on finding out the distribution, such as sex and age, damaged part of the body of 389 TA victims, nature of damage of 389 TA victims, chief complaint of 389 TA victims, nature of damage by Korean medicine code classification, treatment given to 389 TA victims, Extract(Ex) medicine given to 389 TA victims, days in hospital of 389 TA victims. Results : The patients reached korean medicine hospital in fewer numbers from most of TA victims. As neck pain and L-spin sprain, most of symptoms was light and the treatment of medicine as well was limited for TA. The treatment method which was used for treating TA was acupuncture, cupping therapy, physical therapy, Ex medicine. Few ways could use the Ex medicine as well. Conclusions : The achieving rate of treatment was marked highly by using Haenggi(行氣) Hwalhyeol(活血) Guyea(祛瘀) and we confirmed a possibility for the treatment of TA in korean medicine treatment method. It needs to increase all kinds of treatment-ways which can treat successfully and needs to come into application of insurance. Korean medicine method will have possibility to take part in TA injury admission, by presenting basis to prove effectiveness of treatment-ways.

The purpose of this paper is to examine the viewpoints of the different legal systems for the validity of LD Clause and the possibility of gap-filling function of UNIDROIT Principles in International Sales Contract. The results of comparative study between common law system and civil law system, and between CISG and UNCDROIT Principles is as follows: First, common law system distinguishes LD Clause and Penalty Clause, but civil law system including Korean law does not strictly distinguish the difference between them, provided that the liquidated damages are not grossly excessive. Second, CISG does not concerned with the validity of LD Clause but entrust this matter to the law applicable by virtue of the rules of private international law; conversely the Principles follow similar position of civil law system. The possibility of gap-filling of the Principles is more positive in the case of arbitration than in the case of litigation. On the basis of above study, I also checked the LD Clauses of ICC Model International Sales and the Model Contracts of Korean Commercial Arbitration Board. The LD Clauses of there two Model Contract seem very appropriate and reasonable for the reference in practical application. The appropriate, not excessive, LD Clause will contribute not only to eliminate the burden of proof for the actual damages, but also to enforce both parties to perform their obligations in their contracts. Therefore, When we make contract, we should keep in our mind to insert the reasonable and appropriate LD Clause in the sales contract. If not, so to speak, litigated damages are grossly excessive, the Clause may be invalid in some legal system.

The purpose of this paper is to research on the liability for the space damage and the settlement of the dispute with reference to the space activity under the international space treaty and national space law of Korea. The United Nations has adopted five treaties relating to the space activity as follows: The Outer Space Treaty of 1967, the Rescue and Return Agreement of 1968, the Liability Convention of 1972, the Registration Convention of 1974, and the Moon Treaty of 1979. All five treaties have come into force. Korea has ratified above four treaties except the Moon Treaty. Korea has enacted three national legislations relating to space development as follows: Aerospace Industry Development Promotion Act of 1987, Outer Space Development Promotion Act of 2005, Outer Space Damage Compensation Act of 2008. The Outer Space Treaty of 1967 regulates the international responsibility for national activities in outer space, the national tort liability for damage by space launching object, the national measures for dispute prevention and international consultation in the exploration and use of outer space, the joint resolution of practical questions by international inter-governmental organizations in the exploration and use of outer space. The Liability Convention of 1972 regulates the absolute liability by a launching state, the faulty liability by a launching state, the joint and several liability by a launching state, the person claiming for compensation, the claim method for compensation, the claim period of compensation, the claim for compensation and local remedy, the compensation amount for damage by a launching state, the establishment of the Claims Commission. The Outer Space Damage Compensation Act of 2008 in Korea regulates the definition of space damage, the relation of the Outer Space Damage Compensation Act and the international treaty, the non-faulty liability for damage by a launching person, the concentration of liability and recourse by a launching person, the exclusion of application of the Product Liability Act, the limit amount of the liability for damage by a launching person, the cover of the liability insurance by a launching person, the measures and assistance by the government in case of occurring the space damage, the exercise period of the claim right of compensation for damage. The Liability Convention of 1972 should be improved as follows: the problem in respect of the claimer of compensation for damage, the problem in respect of the efficiency of decision by the Claims Commission. The Outer Space Damage Compensation Act of 2008 in Korea should be improved as follows: the inclusion of indirect damage into the definition of space damage, the change of currency unit of the limit amount of liability for damage, the establishment of joint and several liability and recourse right for damage by space joint launching person, the establishment of the Space Damage Compensation Review Commission. The 1998 Final Draft Convention on the Settlement of Disputes Related to Space Activities of 1998 by ILA regulates the binding procedure and non-binding settlement procedure for the disputes in respect of space activity. The non-binding procedure regulates the negotiation or the peaceful means and compromise for dispute settlement. The binding procedure regulates the choice of a means among the following means: International Space Law Court if it will be established, International Court of Justice, and Arbitration Court. The above final Draft Convention by ILA will be a model for the innovative development in respect of the peaceful settlement of disputes with reference to space activity and will be useful for establishing the frame of practicable dispute settlement. Korea has built the space center at Oinarodo, Goheung Province in June 2009. Korea has launched the first small launch vehicle KSLV-1 at the Naro Space Center in August 2009 and June 2010. In Korea, it will be the possibility to be occurred the problems relating to the international responsibility and dispute settlement, and the liability for space damage in the course of space activity. Accordingly the Korean government and launching organization should make the legal and systematic policy to cope with such problems.

We present a study on the development of a practical and quantitative technique for the assessment of the structural health condition with using piezoceramic(PZT) sensors. The electro-impedance-based technique with the PZT patches is very sensitive for evaluation of the incipient and small damage in a high frequency range, and however the commonly traditional modal analysis method is effective only for considerably larger damages in low frequency range. The paper presents the technique in detecting and characterizing real-time damage on the specimen that is an aluminum plate fastened with bolts and nuts by different torques and as well a plate with a crack. By using the special arrangement of the PZT sensors, the required longitudinal wave is generated through the specimen. A large number of experiments are conducted and the different conditions of the specimens, i.e. the location and extent of loosening bolts, and the plate with a crack are simulated. respectively. Since fixing and loosening the loosened bolt is controlled by a torque wrench, we can control exactly the experiment of the different torques. Compared with the simulated healthy condition, we can find whether or not there is a damage in the specimen with using an impedance analyzer with the PZT sensors. Several indices are discussed and used for assessing the different simulated damages. As for the location of bolt loosening, the RMSD is found to be the most appropriate index for numerical assessment and as well the RMSD shows strongly linear relationship for assessing the extent of the bolt loosening, and the frequency peak shift ${\Delta}F$ is used to assess the cracked plate. The possibility of repeatability of the pristine condition signatures is also presented and the appropriate frequency range and interval are uniquely selected through large numbers of experiments.

Ethanol treatment during the brain growth spurt period has been known to induce the death of Purkinje cells. The underlying molecular mechanisms and the role of reactive oxygen species (ROS) in triggering ethanol-induced Purkinje cell death are, however, largely unresolved. We undertook TUNEL staining, western blotting assay and immunohistochemistry for the cleaved forms of caspase-3 and -9, with calbindin D28K double immunostaining to identify apoptotic Purkinje cells. The possibility of ROS-induced Purkinje cell death was immunohistochemically determined by using anti-8-hydroxy-2'deoxyguanosine (8-OHdG), a specific cellular marker for oxidative damage. The results show that Purkinje cell death of PD 5 rat cerebellum following ethanol administration is mediated by the activation of caspase-3 and -9. However, unexpectedly, TUNEL staining did not reveal any positive Purkinje cells while there were some TUNEL-positive cells in the internal and external granular layer. 8-OHdG was detected in the Purkinje cell layers at 8 h, peaked at 12-24 h, but not at 30 h post-ethanol treatment. No 8-0HdG immunoreactive cells were detected in the internal and external granular layer. The lobule specific 8-OHdG staining patterns following ethanol exposure are consistent with that of ethanol-induced Purkinje cell loss. Thus, we suggest that ethanol-induced Purkinje cell death may not occur by the classical apoptotic pathway and oxidative damage is involved in ethanol-induced Purkinje cell death in the developing cerebellum.

Objective : As a result of increasing amount of ultraviolet ray, skin problems including sunburn, rapid skin aging, melanoma, and even skin cancer continue to rise. In the present study, the effect of oriental herbal extract, Daehwanggo(大黃膏,DH) and Daehwanggogasnagbakpi(大黃膏加桑白皮,DS), as external application, on the skin damage, was investigated. Methods : 30 mice were equally distributed into 3 groups : control, UVB-control and UVB-irradiated and DS-treated group. Also mouse melanoma cell lines were cultured. Tyrosinase inhibition was measured to analyze the UN-protection effect. Melanogenesis in the UV-irradiated melanoma cell lines was compared in DS-treated cell line and control cell line. Sample skin from the ear tissue of the 3 groups were analyzed to observe the inflammatory response, T cell differentiation, apoptosis of keratinocytes. Results : The tyrosinase was more significantly inhibited in the DS group compared to DH group. Antioxidative effects was more prominent in DS group when superoxide dismutase was measured. Both the DS- and DH-treated cell lines showed significantly reduced melanogenesis. The reduction of external skin damage including erythematous papule, eczema, keratinocyte, pyopoiesis was observed in the DS- and DH-treated sample cells. In terms of the effect on the skin damage, sunburn cell, activated skin mast cells, secretion of IL-12, manifestation of HSP70, hyperplasia of epithelial cells, MMP-9 and destruction of the collagen were all significantly improved in the DS-treated sample cells. Melanin cells and the apoptosis in the melanoma cell line were decreased. Conclusion : DH and DS were traditionally applied externally for the scald in the oriental medicine. The present study elucidated the possibility of herbal extracts to be used as ultraviolet protectives. Further investigations are needed to assure the clinical application.

Excavated gold brocade, often shows signs of serious damage and contamination from environmental factors such as exposure to soil or human remains. Therefore, most of the conservation procedures are focused on the consolidation of the gold thread and on cleaning with water or organic solvents. Indiscreet cleaning using solvents could damage the gold leaf, which identifies the features of fabric. There is a need to develop cleaning protocols appropriate for relics through the careful analysis of the condition of the relics. This study finds the appropriate cleaning method for the excavated gold brocade. Four different cleaning methods, vacuum cleaning, kneaded rubber eraser cleaning, immersion wet cleaning, and absorption wet cleaning were applied to the excavated gold brocade. The degree of cleaning and damage were examined depending on the cleaning methods, changes to the physical condition (before and after cleaning) were also analyzed through the surface observation. Although immersion cleaning showed the best cleaning result, this method had a risk of damage to the gold thread. Absorption wet cleaning safely eliminated the various soluble contaminants and the rotten smell of relics. Kneaded rubber eraser was suitable for the excavated gold brocade fabric because it can be applied to selective parts, intentionally excluding some sensitive parts such as the gold thread. The vacuum cleaning method required special attention because of a possibility of suctioning off loosely attached gold leaf. Dual cleaning, the kneaded rubber eraser cleaning, followed by the absorption cleaning was the most effective method to preserve and clean excavated gold brocade.

The houses are formed in the lower part of the mountain slope face in most agricultural areas of Korea, and old residents accounting for a large portion of the agricultural populations cannot respond to the evacuation quickly when the landslide happens, and the possibility the life damage occurs is high. Therefore, it is urgent to arrange the measure on this. This study is intended to develop the personal disaster evacuation apparatus that can be installed in the house to minimize the life damage by the landslide and to develop the self-initiative evacuation apparatus. This study suggested the load applicable to the personal disaster evacuation apparatus by quantitatively analyzing the effect of the load of rockslides and avalanches caused by the landslide on the structure. Also, the material property of materials was calculated through the tension and bending intensity test after making the specimen of glass fiber reinforced plastic (GFRP) member. The load weight and material property drawn from this study can be used as the basic material for the stability analysis of the personal disaster evacuation apparatus.
