This paper aims to provide the basic data for the educational direction of global etiquette through the analyses of 1,028 articles appearing in Chosun Daily Newspaper the results of this study are as follows: 1. The articles of global etiquette were classified into the life in public places, the traffic and the public behavior. 1) The contents of the life in public places dealt with restaurants(29.3％), the neighborhood(24.7％), theaters and stadiums(9.7％), hotels and sanitary facilities(8.8％), stores(7.7％), schools and offices(7.0％), airports and public offices(6.6％) and resorts(6.2％). 2) The contents of traffic dealt with the motorists(29.3％), buses(24.7％), taxis(12.3％), subways(10.3％), trains(8.2％), elevators and pedestrian crossing(6.2％), airplanes(4.6％) and parking(4.4％). 3) The contents of public behavior contained the kindness(45.6％), the use of cellular Phone(12.4％), the concession and queues(10.8％), the greeting(10.3％), the responsibility and obeying laws(7.9％), the cleanliness(7.7％), the commercial transaction(2.9％) and the table manner(2.4％). 2. Koreans were negatively evaluated on 1) the kindness at restaurants, the neighbor and strangers and the motorists, 2) there aren't enough greetings being practiced within the neighborhood and at restaurants, 3) The use of cellular phone at theaters and stadiums, schools and offices, buses and subways, 4) The table manner at restaurants, 5) The concession and queues at theaters and stadiums, resorts, the motorists and subways, 6) The responsibility and obeying laws of the motorists, 7) the commercial transaction at restaurants and stores, 8) The cleanliness at restaurants, resorts and hotels and public sanitary facilities. According to this finding, it is recommended that we develop the educational contents and programs of global etiquette which are focused on educating the public on the connection between the living area and how the public should adapt and behave

This study was executed for the purpose of investigation of the EMFs exposures of personal and electronic environment. This study examines ELF-EMFs of electric appliances, subways and occupational and non-occupational human exposures, using EMDEX II (for 40 - 800Hz, Enertech Consultant, Inc.), from October 1995 to March 1996. Among the electric appliances examined, a massage unit showed the highest mean value of 247.07 $\mu$T, followed by an electric blanket of 5.24 $\mu$T. Indoor levels of EMF in subways exceerlcd 0.2 $\mu$T of the Swedish Guideline. The mean personal exposure levels of occupational group were 0.18 $\mu$T, while the personal EMF level of non-occupational group were 0.07 $\mu$T. Occupational group were exposed more highly while at work. However, the EMF levels during nonwork and sleep exposures between occuptional group and nonoccupational group were about the same. Estimates of time-intergrated exposure indicated that utility-specipic job classifications received about one-half or more of their total exposure on the job. Finally, this study would provide significant data for future research for exposure to magnetic fields, and more detailed study and research are necessary.

In order to introduce P.S.M. system adequate to domestic construction first, many cases similar to advanced foreign P.S.M. system have been collected and compared to the domestic situation. Then, the current safety management status of bridges, subways, apartment and office building construction are investigated while visiting interview, using questionnaire at site have being done. The potential hazard and measurement have been investigated for each kind of works, and the domestic introducing method of P.S.M. system is analyzed with expert discussion. In order to represent how to make out P.S.M. plan, the questionnaire is made out using each five place for bridge, subways, apartment and office building. As the weight factor for potential hazard of each work obtained from more than forty site places, is produced and shown. Also, a direction the recommendation is suggested to improve tool in each construction site with work schedule. It is thought that proposed schedule contributed to keeping in safe business administration of each company in decreasing many effort at the construction site.

Recently the characteristics of those who committed serious terrorist crimes are not directly related to the direct command system of a specific terrorist organization (ex. IS) but are influenced by the political propaganda of terrorist organizations online, Terrorist crime under the loose form of the terrorist organization. Therefore, this study suggests ways to improve countermeasures against terrorism in metropolitan subways. Although it is important for the prevention of terrorism in the subway, it is important for the police officers of the subway police and the special police officers of the railway to have a physical limit to take charge of them, and after confirming that improvement measures are necessary, And pointed out the possibility of establishing independent security departments where judicial and administrative control is not feasible to grant police rights. In addition, I pointed out how to improve the safety of subways in the metropolitan area through the recruitment of core job candidates and the identity survey during the subway operation. Furthermore, it was confirmed that a special council on terrorism, which can take into consideration the characteristics of subway terrorism, such as airports and ports, is required to be established in charge of terrorism prevention under the current Anti-Terrorism Act. Finally, it is once again emphasized that the strengthening of the powers of the counterparts to terrorism must inevitably limit the basic rights of the people, so the principle of proportionality must be observed in their activities.

Recently, the Korean government promoted the construction of metropolitan express subway to connect major transportation hub in the metropolitan area within 30 minutes. Most stations of the metropolitan express subway are connected to existing subway stations, so the importance of transfer increased. Although many studies have been conducted on the effect of transfer penalty on route choice, there are few studies on the transfer behavior of the metropolitan express subway. Therefore, in this study, a transfer behavior analysis was conducted on the Shinbundang Line, a representative metropolitan express subway. To analyze the transfer behavior according to the degree of traffic congestion and the presence of fare payment, route choice models were made using transport card data divided according to week, time, and user characteristics. As a result of the analysis, users of the metropolitan express subway had greater disutility to the transfer waiting time compared to the transfer moving time. Furthermore, especially during the peak time, EIVM(Equivalent in-vehicle minutes) of the transfer waiting time was 3.51. In this study, EIVM for metropolitan express subway users were analyzed to be 2.6 minutes, which is significantly lower than the results of previous studies on subways. This suggests that there is a difference in the transfer penalty between subways and metropolitan express subway, and that it is necessary to apply the transfer penalty between subways and express subway differently when forecasting subway traffic demand.

The light rail transit (LRT) having bus lines as subsystem is being constructed or planned in the suburban area of metropolitans and medium size cities. However, there is difficulty in establishing the service coverage (SC) of the LRT because the LRT is a completely new transit mode in Korea. The purpose of this study is to provide the basic data and techniques to be used for establishing the SC of the future LRT by understanding the SC characteristics of buses and subways and building models to estimate the walking distances of their users. Busan City is selected as the study city and the SC's of buses and subways are surveyed simultaneously. A total of 9 variables for 82 stations are collected and the cluster analysis is conducted about the variables. The station areas are divided to three types of CBD (Central Business District), sub-CBD and regional center based on the analysis. A station in each area is selected as the study station. At the walking distance (WD) analysis for each mode, the 80 percentile WD of the subway is 672 m and that of the bus is 472 m. In comparing the SC's of both modes by the type of station areas, there are not significant differences between the SC's of sub-CBD and regional center except CBD. At analysis of the relationship between the personal attributes and the WD, for subway users the WD of female is longer than that of male and apartment residents use subway more positively than single house residents do. For the models to estimate the walking distances, the simple regression models were built employing the income as independent variable by dividing the stations into CBD abd non-CBD stations.

Construction incidents, mechanisms and causes in Geotechnical Engineering have been closely reviewed for the safety assurance during design and construction stages. The safety assurance is clearly related to the observational method in which design is reviewed during construction and contingency actions are undertaken successfully to minimise any potential failures. The observational method has been extensively applied for the construction of subways underground structures, dams and many important Civil Engineering projects in the past 20 years. But the number of serious construction incidents are growing for the past several decades. Therefore present development of observational method and improvement techniques are introduced with some case histories.
