The purpose of this study is to identify characteristics and improvements of the climate change vulnerability analysis methods to build a safe city from disasters. For this, an empirical analysis on sea level rise disasters was performed focusing on Heaundae-gu in Busan. For the analysis, Census output areas and Dongs were set as analysis unit and their disaster vulnerability was analyzed. Improvements were reviewed through the comparison and review of analysis process and results. According to analysis results, Modifiable Areal Unit Problem(MAUP) which gives different results according to aggregate unit occurs. Improvements were induced by analysis process, and it was found that in spatial unit setting stage that becomes the base of analysis, analysis unit adjustment, score computation method adjustment, and clearer analysis method for each disaster type would be needed. In analysis execution stage, it was thought that weighting according to variables, diversification of variables, and exclusion of subjective analysis selection method would be needed. It is expected that accurate the total disaster vulnerability analysis will be the base for the improvement of efficiency in urban resilience responding to future weather changes.

This paper focuses on the study of a development direction of the industrial security Expert system. First of all, in order to manage Industrial security system, we need to have law, criminology, business and engineering professionals as well as IT experts, which are the multi-dimensional convergence professionals. Secondly, industrial organizations need to have workforce who can perform security strategy; security plan; security training; security services; or security system management and operations. Industrial security certification system can contribute to cultivate above mentioned professional workforce. Currently Industrial Security Expert(ISE) is a private qualification. However, the author argued that it have to be changed to national qualification. In addition, it is necessary that the system should be given credibility with verifying the personnel whether they are proper or not in the their field. In terms of quality innovation, it is also necessary that distinguish the levels of utilization of rating system of the industrial security coordinator through a long-term examination. With respect to grading criteria, we could consider the requirements as following: whether they must hold the degree of the industrial security-related areas of undergraduate or postgraduate (or to be); what or how many industrial security-related courses they should complete through a credit bank system. If the plan of completing certain industrial security-related credits simply through the credit bank system, without establishing a new industrial security-related department, has established, then industrial security study would be spreaded and advanced. For private certification holders, the problem of the qualification succeeding process is important matter. Additionally, it is necessary to introduce the certifying system of ISMS(Industrial Security Management System) which is a specialized system for protecting industrial technology. To sum up, when the industrial security management system links the industrial security management certification, industrial security would realize in the companies and research institutions dealing with national key technology. Then, a group synergy effect would occurs.

A text-based communication system has been developed with a communication function on AIS and display and input function on ECDIS as a way to complement voice communication. It features no linguistic error and is not affected by VHF restrictions on use and noise. The text communication system is designed to use messages for clear intentions and further improves convenience of users by using various UI through software. It works without additional hardware installation and modification and can transmit a sentence by selecting only via Message Banner Interface without keyboard input and furthermore has a advantage to enhance processing speed through its own message coding and decoding. It is determined as the most useful alternative to reduce language limitations and recognition errors of the user and solve the problem of various voice communications on VHF. In addition, it will help to prevent collisions between ships with decrease in VHF use, accurate communication and request of cooperation based on text at heavy traffic areas.

In this study, we investigated the methods of improving the capturing ability of acid fume by assessing the performance of slot-type external hood installed on both sides of an open surface tank for acid washing process. A field survey and the results of computational fluid dynamics revealed that capturing performance of existing hoods is very poor. To solve such problem, 'push-pull hood' that pushes from one side of an open surface tank and pulls on the other side was suggested. The initial prediction was that if a push-pull hood is used, the acid fume of an acid-washing tank surface could be moved towards the hood through the push flow. However, this study has confirmed that if the push flow velocity becomes too high, it could spread to other areas due to flooding from the hood. Therefore, if the push air supply is maintained at around 25 $m^3/min$(push 10 m/s), proper control flow is formed on the surface of a tank and acid fume that stayed at the upper part of the tank is smoothly captured toward the hood, significantly enhancing the capturing performance.

The objectives of this study were to access climate change by global warming in Korea, and to investigate its effects on production efficiency of lactating dairy cows. Two regions, Daegu and Daekwanryung, were selected to represent a warm and a cold area, respectively. Time-series analyses on meteorological records for 25 years (from January 1, 1988 to December 31, 2012) revealed significant and different climate changes in two regions. In the warm area there has been a significant (P<0.05) increase in low temperature during the summer, which can cause heat stress to the animal. On the other hand, a decrease in low temperature during the winter was observed in the cold region (P<0.01), and cold stress in winter can thus be an issue in this region. Simulations using a model integrated the Korean feeding standard for dairy cattle and the environmental effect module of Cornell Net Carbohydrate and Protein System, indicated that a reduction in feed efficiency can be a problem during the winter in the cold region while during the summer in the warm area. We conclude that the effect of climate change by global warming varies in different areas in Korea and a region-specific management strategy should be developed in order to maintain productivity, health and welfare of lactating dairy cows.

Being latecomers to the industrialization, Pacific rim countries except the U.S.A. are doing very little in developing the universal certification system. One should note that Asian Pacific region enjoys the highest economic growth rate, and there is a good possibility that it will be the center of economic activities of the world in the next century. It appears that ISO and CEN share similar specifications in numerous areas. ASNT is being changed to cope with the trend with the introduction of ACCP. Although we may have to adopt the new system someday, we should pay attention and make concerted effort to include our own practice in the global standards. We are the countries in the Far East Region with similar culture and tradition, which are quite different from those of western countries. We hope that Japan should play an important role in this matter, who has been chaired the ISO TC135 since 1993. In the beginning of this decade, there has been a trivial but troublesome matter that who is representing the NDT Society or member countries in Asia-Pacific Conference on NDT. The problem appears to be solved since the establishment of FENDT For the next decade, actually next centry, FENDT will have to accomplish another important role for countries in the Far East Region to form a strong coalition for its survival in the western dominant world. Immediate issue is to establish Far East Working Group for Harmonization and Mutual Recognition of Qualification and Certification of NDT Personnel. To realize this Japan must play a leading role with the cooperation of expanded FENDT member countries including China and Russia. As the continued prosperity expected in this region, FENDT should continue its role for the next centry. We, the FENDT countries, must move forward for internationalization(國際化). However' we must realize that it all start from SELF IDENTI-FICATION. We can identify ourselves by actively participating in FENDT. I would like remind you the concluding remark that I have made in the congratulatory speech at JSNDI 40th Anniversary Conference and FENDT'92. JSNDI is too precious to be Japan's sole possession Staling from the Far East, JSNDI shall become one of the loaders of the world. I sincerely hope that JSNDI take initiatives and leaderships in the future activities. of FENDT countries. I would like to close my talk with "We must hang together, or We shall be hang seperately."

The great damage to the mature fruits in the orchard caused by the fruit sucking moths including unidentified species, is a troublesome problem in recent years in Korea. The present survey is, there-fort, carried out to clarify the ecological characters, especially kinds of these harmful moths and their damage at Suwon and Jinju fruit growing areas, in order to establish the foundation of the control. Some results obtained through the survey are as follows: It is investigated that the most noticeable group of these noxious moths, identified 10 species, belongs to subfamily Catocalinae of the family Noctuidae. Although there was already recorded as the harmful moths on the fruits such 4 species as Oraesia excavata B. Adris tyrannus amurensis S., Calpe thalictri B. and Dermaleipa juno Delman, it is additionally identified to be 6 species in 1968 including Oraesia emarginata F.,O. lata B., Agrotis ipsilon H., Chrysorithrum amatum Bremer et Grey, Dinumma deponens W. and Trachea atriplicis L. of the fruit sucking moths in Korea. Of all these noxious moths damaged, O. excavata is the most harmful, following by O. emarginata and Adris tyrannus. The fruit sucking moths attack on all kinds of mature fruits from early summer to late fall and behave entirely nocturnal. The damage ratio in percentage of these moths is $8.9\%$ on grape in Suwon, and $3.4\%$ on pears in Jinju.

It is noted that the paper mapping system for University Building Facility has many limitations in terms of data maintenance, real-time GIS data acquisition, and economic efficiency. The aim of this research was to evaluate an operational potential of an on site real-time mobile GIS technique to resolve the problem faced in the university. The idea is based upon the recent trends in the field of 'Telecommunication and Information Technology' that uses a PDA (personal Digital Assistants), wireless network computing, mobile computing, etc. A real time mobile GIS approach has been adopted, in which a PDA is linked to a wireless internet and field workers record data on the computer at the site and analyse data on site. While there should be a considerable number and variety of factors associated with real-time mobile GIS quality, this research focuses on three criteria that are identified as fundamental to customer requirements; (1) data quarry (2) spatial analysis (3) real-time GIS database building. 'Art--empirical study for a case study facility has been conducted to confirm the validity for the system. The system has been checked experimentally, enabled the field users to quarry the data required simply and execute spatial analysis (buffer, overlay etc.,) accommodating versatile alternatives on the site. Detailed visual maps can be generated over large areas quickly and easily. The PDA interface, in particular, were ideally suited for field users to interactively displaying positional information with attribute data. This system has shown to be quite convenient to maintaining a highly reliable database since it could playa crucial role in documenting at real-time basis temporal and spatial changes occurred in the facilities. It is anticipated that this research output will greatly serve to introduce the reliable and cost-effective facility mapping system in the university by overcoming serious constraints suffered from the past non-real time mobile GIS approach.

Environmental problems can be dealt in the diverse areas such as engineering, public administration, and law. However, the education on environmental preservation is conceived as the fundamental solution for environmental problems, because the education can make the person of action. Specifically, building the attitude and habit of environmental preservation through environmental education is the effective and efficient way of environmental preservation. This research was conducted to develop an education system that is designed to build students' attitude and habit of environmental preservation through acquiring knowledge and functions of natural environment. The proposed system supports diverse learning activities such as writing, drawing, listening natural sounds and music, and problem solving. The system is technically designed on the Web to promote students' creativity and autonomy, and also are theoretically based on constructivism to build the will of environmental preservation. Moreover, the proposed Web-based system includes diverse functions such as classes, material resources, environmental quiz pool, environmental work gallery, which motivate students' learning activities. Therefore the proposed Web-based system is expected as an effective tool to achieve the goals of environmental education such as acquiring environmental knowledge and functions, building attitude of environmental preservation, and participating in the environmental preservation activities.

Ever since the open and reform policy in 1987, China has adopted the socialistic market economy system and has been moving forward in economic reform. This gradually expanded their market economy. The open and reform policy achieved the highest average annual GDP growth rate of 9% and helped the country maintain high growth. China's economic growth in recent years has a lot to do with the international trading and direct investment by foreign corporations. China's entry into the WTO dramatically increased their amount of capital and investments due to their aggressive investments with foreign corporations. It is quite amazing that investments in China has been constantly increasing while the direct investments worldwide is decreasing. Moreover, increase in such investments is contributing to China's job creation, as well as, the expansion of international trading. When international economic exchange started between Japan and China in the 1970s, it was in the form of aid for developing countries, hence the collection of the investment was out of the question. It was in the 1990s that Japan started the full-scale investments with China and it was mostly centered in transfer of the production base. Japanese corporations aim was to mass produce goods less expensively using abundant and cheap labor and to sell them to Japan and other countries. The amount of Japan's exports and imports compared with China is increasing every year but the trade deficit has gone into the red. The dollar amount has been decreased from $ 27 billion in 2001 to $ 18 billion in 2003. The problems and damages in the system of justice and administrative confrontation that Japanese corporations are facing are continuously at a stand-still even after China's entry into the WTO. It has been 20 years since Japan's advance in China and during that period, the Japanese corporations brought many changes ranging from exports/imports to direct investment. Although Japan's new corporations tend to be located in the mid-western part of China, rather than the coastal areas, the region itself is not the cause for the confrontation. The problem stems from the Japanese treating the Chinese as if they were Japanese because they look similar due to their Asian ancestry. In reality the Chinese have completely different ways of doing business. Here we will take a look at the international trading and direct investment of Japanese corporations in China and study the conflicts that occurred in business transactions with China through real examples.
