Implementation of semi-public management system of intra-city bus achieve excellent results but there are some side effects like increase of the fatal traffic accidents. This study tries to develop decision making model of measures of reducing traffic accidents following implementation of semi-public management system of intra-city bus. And survey with traffic experts and analytic hierarchy process are used for data survey and analysis. Quantitative measures and qualitative measures are suggested as high assessment items of AHP. Quantitative measures of low assessment items composed of a raise in the number of bus and safety device installation, facility supplement of bus stop, supplement of pedestrian protection facility, traffic safety assessment and supplement. Qualitative measures composed of system organization, redesign bus route, reinforcement of education, campaign and enforcement. The results of this study are as follows. First, the result turns out more weights are calculated on quantitative measures than on qualitative measures. Second, It is turned out in order of facility supplement of bus stop and traffic safety assessment and supplement as the quantitative measures. Third, as qualitative measures, system organization and redesign bus route are in the order. The results of this study are considered to be a basic data which can be referred if measures on the decrease of traffic accident are established and implemented in other cities and provinces.

In order to investigate the adolescent's beverage drinking pattern and its related ecological factors, a questionnaire survey was conducted with the subjects of 920 middle and high-school students,450 boys and 470 girls, residing in 4 cities of the Chungnam area. Of the subjects 65% liked, or liked very much, beverages and only 3.7% did not like beverages. They drank beverages 4.3 $\pm$ 4.0 times a week on average, but 10.4% of them drank beverages more than twice a day. Male students drank more frequently than the females. The intake frequency of carbonated drinks was 1.7 $\pm$ 2.3 a week which was about 40% of the total beverages. However, more students drank mainly ion beverages (33.6%) than carbonated drinks (28.7%). As the students took more balanced food and ate more regularly, their beverage drinking frequency decreased and those taking carbonated drinks also tended to decrease. The more frequent the students took fast food, the more frequent they drank carbonated beverages. The drinking frequencies for beverages or carbonated beverages were also less in students eating cooked rice with sidedishes as breakfast than in students eating others. The drinking frequency for carbonated drinks showed significant correlations with the students' activities such as the time spent using computers and watching TV got longer, the drinking frequency for soft drinks was also higher. When nutritional knowledge was higher, drinking frequency for carbonated drinks got lower. In conclusion, to make the adolescents improve their attitudes toward drinking beverages and to prevent excessive drinking of carbonated drinks, they should be educated not only on the nutritional knowledge and the proper intake of beverages, but also on good dietary habits including balance, regularity, and types of meals. Proper snacking and fast food consumption also should be taught. Since ion beverages were taken more frequently than carbonated drinks among adolescents, further study is recommended on the impact of excessive intake of ion beverages.

Usage of underground space is increasing at metropolitan city. More than 90% of flood damages have occurred at downtown of metropolitan cities. In order to prevent and/or minimize the flood-induced damage, an underground rainwater detention cavern was proposed to be built underneath existing structures. As for underground caverns to be built for flood control, multi-caverns will be mostly adopted rather than one giant cavern because of stability problem. Because of the stress concentration occurring in the pillars between two adjacent caverns, the pillar-stability is the Achilles' heel in multi-caverns. So, a new pillar-reinforcing technology was proposed in this paper for securing the pillar-stability. In the new pillar-reinforcing technology, reinforced materials which are composed of a steel bar and PC strands are used by applying pressurized grouting, and then, by applying the pre-stress to the PC strands and anchor body. Therefore, this new technology has an advantage of utilizing most of the strength that the in-situ ground can exert, and not much relying on the pre-cast concrete structure. The main effect of the pressurized grouting is the increase of the ground strength and more importantly the decrease of stress concentration in the pillar; that of the pre-stress is the increase of the ground strength due to the increase of the internal pressure. In this paper, ground reinforcing effects were verified the stress change in pillar is obtained by numerical analysis at each construction stage. From these results, the effects of pressurized grouting and pre-stress are verified.

Background and Aims: Liver cancer is a major health problem in low-resource countries. Approximately 55% of all liver cancer occurs in China. Hebei Province is one of the important covering nearly 6% of the population of China. The aim of this paper was to explore liver cancer mortality trends during past 30 years, and provide basic information on prevention strategies. Methods: Hebei was covered covered all the three national surveys during 1973-1975, 1990-1992, and 2004-2005 and one provincial survey during 1984-1986. Subjects included all cases dying from liver cancer in Hebei Province. Liver cancer mortality trend and geographic differences across cities and counties were analyzed. Results: There were 82,878 deaths in Hebei Province during 2004-2005 with an average mortality rate was 600.9/10,000, and an age-adjusted rate of 552.3/10,000. Those dying of cancer were 18,424 cases, accounting for 22.2% of all deaths, second only to cerebrovascular disease as a cause of death. Cancer mortality was 133.6/100,000 (age-adjusted rate was 119.2/100,000). Liver cancer ranked fourth in this survey with a mortality rate of 21.0/100,000, 28.4/100,000 in males and 13.35/10,000 in females, accounting for 15.7%, 17.1% and 13.4% of the total number of cancer deaths and in males and females, respectively. The sex ratio was 2.13. Since the 1970s, liver cancer deaths of Hebei province have been increasing slightly. The crude mortality rates in the four surveys were 11.3, 16.0, 17.4, 21.0 per 100,000, respectively, with age-adjusted rates fluctuating during the past 30 years, but the trend also being upwards. There is a tendency for the mortality rates to be higher in coastal than mountain areas, and is relative lower in the plain area, with crude mortality rates of 25.3, 22.1, and 19.1 per 100,000, respectively. There were no notable differences in cride data between urban and rural, but the age-adjusted mortality rate in rural was much higher. Conclusion: Our study indicated that the mortality of liver cancer in Hebei Province is lower than the national average level. There is a slightly increase trend, especially in some counties. Liver cancer is a major health problem and it is necessary to further promote prevention strategies in Hebei province.

Background: Health-care research is a neglected discipline in Pakistan and research related to esophageal cancer (ranks 9th in Pakistani males and 5th in females) is no exception in this regard. Particularly, there are no data available to delineate the overall status of esophageal cancer epidemiological studies in Pakistan. This study describes the first ever effort to make a systematic quantification, in an attempt to provide a road-map to all stakeholders for designing appropriate epidemiological, diagnostic and therapeutic strategies. Materials and Methods: International (PubMed, ISI Web of Knowledge) and local (PakMedinet) scientific databases as well as Google search engine were searched using specified keywords to extract relevant publication. Well-defined inclusion criteria were implemented to select publications for final analyses. All data were recorded by at least 3 authors and consensus data were entered into and analyzed for descriptive statistics (such as frequencies, percentages and annual growth rates) using Microsoft Excel and SPSS software. Results: A total of 79 publications fulfilled the inclusion criteria including 20 publications for which full texts were not available. Of the 79 publications, 59 (74.6%) were original/research publications, 5 (6.3%) were case reports, 4 (5.1%) were research communications, 2 (2.5%) were review articles, 1 was (1.2%) correspondence and 8 (10.1%) were undefined categories. Only 13 (<20%) cities of Pakistan contributed towards the 79 publications. On average, only 1.9 relevant publications/year were published from 1976 (year of first publication) to the present. Alarmingly, a decline in the annual growth at -4.1% was recorded in the last six years. Conclusions: Esophageal cancer research is largely unfathomed in Pakistan. Urgent/dramatic steps are required by all concerned to address this common (and under reported) cancer of Pakistan.

Our recent studies conducted in South America have shown that mycotoxin contamination of red chili peppers (RCPs) may be associated with an increased risk of gallbladder cancer (GBC). Whether this relationship exists in India, a country with a high incidence of GBC and high consumption of RCPs, is unclear. We therefore measured concentrations of aflatoxins (AFs) and ochratoxin A (OTA) in RCPs from areas of low, medium, and high incidence of GBC in India, and compared these concentrations with GBC incidence in each area. Twenty-one RCP samples were collected from nine cities (eight from a low-incidence area, five from a medium-incidence area, and eight from a high-incidence area). Concentrations of AFs and OTA were measured using high-performance liquid chromatography. No significant differences in mean concentrations of AFs and OTA were found in the three areas. AFB1 levels in the low-incidence area ($10.81{\mu}g/kg$) and high-incidence area ($12.00{\mu}g/kg$) were more than 2.2 and 2.4 times higher compared with the maximum permitted level of AFB1 in spices ($5.0{\mu}g/kg$) set by the Commission of the European Communities, or that ($4.4{\mu}g/kg$) obtained in our previous study in Chile. Our results show that the mean concentrations of mycotoxins in RCPs are similar among the three areas in India with different incidences of GBC. Further studies with human subjects are needed to evaluate any association between AFB1 and GBC.

It is one of the most crutial thing to secure efficient infrastructure of social infrastructure Including rna drinking water, sewer, gas, and electricity, etc. in modern society. Among them, the sourer system need to be properly maintained so as to sustain water quality over the large watershed thereby to provide reasonable level of living environment A few municipalities and private firms have so in been using sewer management system for assessing existing sewer network and auxiliary facilities. Such existing system can only provide functions to manage the sewer pipe itself and they can not fully estimate the amount of sewage water over the pipe through 4he network analysis due to the deficiency of the system Such a limited sewer network analysis function can only analyze the whole network under the assumption of uniformity. The results from such a process can not be fully implemented in the field. Therefore, this study emphasized the development of a sewer management system which can provide practical values from network analysts considering areal peculiarities using a zoning map utilizing a GIS. The system can support analyzing scenarios due to the changes of sewer amounts from the changes of population densities and rainfall amounts not to mention of calculating sewer amount for individual sewer pipes. furthermore, the system can support the decision making for better designing sewer facilities from the expansion of metropolitan areas and constructing satellite cities. Eventually, it will contribute to enhance the effectiveness of sewer-related works and services for residents as well as supporting a decision making for minor and major trouble-shootings.

Since 2000, ubiquitous cities are spread over Korea by government's supporting project for ubiquitous city construction. But recently problems such as low perception of ubiquitous city are issued. There is just a few studies about a creation of citizen centric ubiquitous city service even though there have been several studies and policies to overcome such problems. There is not enough research on applying ubiquitous city service effectively at the stage of ubiquitous city plan. To solve this problems, this study ultimately aims to suggest essential ubiquitous city service applied at that stage to guarantee minimum quality of ubiquitous city. The expert survey method was employed to select essential ubiquitous city service. To achieve this goal, First, a survey performed by 163 local government officers to know current status of the ubiquitous city construction project. Second, another survey was performed for about 30 days by 38 experts worked at local public official and ubiquitous city organization to select essential ubiquitous city service. Finally we suggested 14 essential ubiquitous city service from the several viewpoints, which were universality, industry growth, social welfare, effective city management. And we analyzed the differences between ubiquitous city services written 14 ubiquitous city plan and essential ubiquitous city services.

Although the South Korean organic food market is in the infancy compared to other industrialized countries, Korean consumers'interest in organic food and retail stores devoting space to organic products have been rapidly increasing. Despite the fact of organic food popularity, the term "organic" is interpreted differently by individuals. As opposed to the US, Japan and the EU where have operated an integrated organic food labelling system, Korea has adopted complex organic labelling systems regulated by several different government bodies. As a result, complicated food labelling standards make consumers confused when purchasing organic foods. Furthermore, in terms of country of origin (COO), it is argued by a lot of researchers that COO effects vary from product to product and from country to country; moreover, other informational cues such as brand and price can influence COO effects. In modern society, COO labelling has been complicated, due to the sourcing, manufacturing and market locations of merchandise spread over the world. Accordingly, the evaluation of COO effects has become complex. In order to examine these issues, a quantitative research was selected to classify the commonfeatures of organic food consumers and construct statistics such as the extent to which people are aware of organic food and COO labellingvia a questionnaire which took place in two cities in Korea with a cluster sample of 161 organic food purchasers. As for the data analysis, one-way analysis of variance (ANOVA), T-tests, bivariate crosstatulations with Cramer's V were conducted,depending on the characteristics of variables and the assumptions the research data need to fit. It has been concluded that in general, Korean organic consumers comprehend the term "organic"in a closer way to the general concept rather than technical term, thus people do not appreciate environmentally labels which include organic food labels, although marital status influence the degree of label awareness, regardless of gender, age, education level and so on. Regarding COO effects on organic food, home organic products were Korean consumers'first choice over those from industrialized countries and developing nations. Specifically, in processed organic product category, domestically cultivated and processed organic products were absolutely preferred to leading national brands produced with imported ingredients and international brands. However, due to a lack of checks of ingredients' COO, consumers tend to purchase a leading national organic food brand, believing that it is a pure organic food sourced domestically. As a consequence, this research has suggested some important managerial implications and future research directions. In order to prevent consumer confusion when buying organic foods, it should be noted that consumers do not comprehend the organic food certifications, due to complicated labelling systems for organic produce and processed organic foods. Therefore, government bodies related to organic food distribution have to know consumers' perception of organic food labels and the significance of customer-oriented labels and reestablish labelling standards. Similarly, public advertising should be followed to raise public awareness of the labelling to enable customers to have the correct information. In addition, not only international marketers but also domestic marketers need to understand COO images and also the influence COO of ingredients has on the image of an organic product.
