Objectives: This study was performed to examine the factors affecting re-smoking in male workers. Methods: A self-administrated questionnaire survey was conducted during April 2003 to examine the smoking state of 1,154 employees of a company that launched a smoking cessation campaign in1998. Five hundred and eighty seven persons, who had stopped smoking for at least one week, were selected as the final study subjects. This study collected data on smoking cessation success or failure for 6 months, and looked at the factors having an effect on re-smoking within this period. This study employed the Health Belief Model as its theoretical basis. Results: The re-smoking rate of the 587 study subjects who had stopped smoking for at least one week was 44.8% within the 6 month period. In a simple analysis, the re-smoking rates were higher in workers with a low age, on day and night shifts, blue collar, of a low rank, where this was their second attempt at smoking cessation and for those with a shorter job duration (p<0.05). Of the cues to action variables in the Heath Belief Model, re-smoking was significantly related with the perceived susceptibility factor, economic advantages of smoking cessation among the perceived benefits factor, the degree of cessation trial's barrier of the perceived barriers factor, smoking symptom experience, recognition of the degree of harmfulness of environmental tobacco smoke and the existence of chronic disease due to smoking (p<0.05). In the multiple logistic regression analysis for re-smoking, the significant variables were age, perceived susceptibility for disease, economic advantages due to smoking cessation, the perceived barrier for smoking cessation, recognition on the degree of harmfulness of environmental tobacco smoke, the existence of chronic disease due to smoking and the number of attempts at smoking cessation (p<0.05). Conclusion: From the result of this study, for an effective smoking ban policy within the work place, health education that improves the knowledge of the adverse health effects of smoking and the harmfulness of environmental tobacco smoke will be required, as well as counter plans to reduce the barriers for smoking cessation.

Recently, a growing number of copyright infringement websites have illegally copied and posted works such as broadcasting, movies and music, and posted advertisements to make profits. The research is aimed at finding solutions by analyzing the current status of advertisements on copyright infringement websites. The results of this study are as follows. First of all, there are many advertisements harmful to teenagers, such as casinos, betting, games, adult products, and adult meeting, which is necessary to deal with. Secondly, there were many unethical advertisements on copyright infringement websites, but there were also many advertisements from famous companies. Advertisements from large companies and famous brands are also being executed continuously, which can create trust in illegal sites. Therefore, the government, advertisers, citizens, and academia should participate in a campaign to root out the use of illegal websites because it is impossible to eradicate them by crackdown alone. In this paper, we pointed out the practical problems of advertising execution, the main source of revenue for copyright infringement websites, and presented a comprehensive solution.

This study was intended to investigate recognition of the general public on water pollution and nonpoint pollution, and to promote participation of the common people in prevention and management of nonpoint pollution by investigating the necessity and participation in the education for reducing the nonpoint pollution. To this end, this study conducted questionnaire on 1,000 male and female adults over 20 years of age nationwide who are registered in Onpanel. The questionnaire was comprised of recognition on water pollution, preventive activity for nonpoint pollution, countermeasures for preventing nonpoint pollution, necessity of national education for reducing the nonpoint pollution, recognition of promotion and campaign participation, and revitalization of organization for reducing the nonpoint pollution. As a result of the questionnaire investigation, interest in water pollution of respondents was high, and specially, interest in the nonpoint pollution was higher when age, academic level, and income were higher that effectiveness of promotion and education on the source of nonpoint pollution is expected to be increased. Respondents recognized the effect of education on reducing the nonpoint pollution positively when they had higher interest, information, education and experience related to the reduction activity of nonpoint pollution. Therefore, formation of sympathy of the public is positively necessary for the nonpoint pollution management, and provision of civil activity program that increases information on the nonpoint pollution, education, and participation in reduction activity and easy promotion with high information communicability should be conducted continuously.

This study aims to understand the time-based moving pattern and suggest management strategies through surveying the number of visitors from 7 a.m. to 7 p.m. for 3 days of each season in 3 key sites (Jeungsimsa district, Wonhyosa district and Jungmeorijae) of Mudeungsan Provincial Park. Majority of visitors who entered through Jeungsimsa district and Wonhyosa district visited the Mudeungsan provincial park from 9 a.m. to 2 p.m., and the number of enterers reached the peak from 10 to 11 in the morning. Majority of the visitors left the Mudeungsan provincial park from noon to 5 p.m.. The number of leavers showed the peak between 2 and 4 in the afternoon. Most of visitors who moved via Jungmeorijae from 11 a.m. to 3 p.m. climbed toward Jangbuljae or Jungbong or came down to Jeungsimsa district or Wonhyosa district. The number of enterers hit the highest from 11 a.m. to 1 p.m.. However, there was no stark difference in the time-based moving pattern of each season and days of week. The special intensive management such as providing visitor service, conducting a campaign and restoring the damaged land in concentrated site and time is needed for conserving natural resources and improving visitors satisfaction.

This paper preliminarily investigates the effectiveness of various control systems, such as passive, active, semiactive and hybrid control, for seismic protection of cable-stayed bridges by examining the ASCE first generation benchmark problem for a cable-stayed bridge. This benchm.0.00000ark problem considers the cable-stayed bridge that is scheduled for completion in Missouri, USA In 2003. Seismic considerations were strongly considered in the design of this bridge due to location of the bridge and its critical role as a principal crossing of the Mississippi River. Based on detailed drawings of this cable-stayed bridge, a three-dimensional linearized evaluation model has been developed to represent the complex behavior of the bridge. A set of eighteen evaluation criteria has been developed to evaluate the capability of each control system. In this study, four passive control systems, one active control system, two semiactive control systems and three hybrid control systems are considered. Numerical simulation results show that all the control systems are effective in reducing the responses of the benchmark cable-stayed bridge under the historical earthquakes. To get good performance, however, the passive control systems need quite large control forces compared to other control systems. The simulation results also demonstrate that the passive, semiactive and hybrid control systems are robust to the stiffness uncertainty of the structure. Therefore, the semiactive and hybrid control systems are more appropriate in real applications for full-scale civil infrastructures.

Plasmodium vivax merozoite surface protein-1 (PvMSP1) gene codes for a major malaria vaccine candidate antigen. However, its polymorphic nature represents an obstacle to the design of a protective vaccine. In this study, we analyzed the genetic polymorphism and natural selection of the C-terminal 42 kDa fragment within PvMSP1 gene ($PvMSP1_{42}$) from 77 P. vivax isolates, collected from imported cases of China-Myanmar border (CMB) areas in Yunnan province and the inland cases from Anhui, Yunnan, and Zhejiang province in China during 2009-2012. Totally, 41 haplotypes were identified and 30 of them were new haplotypes. The differences between the rates of non-synonymous and synonymous mutations suggest that $PvMSP1_{42}$ has evolved under natural selection, and a high selective pressure preferentially acted on regions identified of $PvMSP1_{33}$. Our results also demonstrated that $PvMSP1_{42}$ of P. vivax isolates collected on China-Myanmar border areas display higher genetic polymorphisms than those collected from inland of China. Such results have significant implications for understanding the dynamic of the P. vivax population and may be useful information towards China malaria elimination campaign strategies.

Purpose: Annual influenza vaccination is the best strategy to prevent healthcare-associated influenza transmission. Influenza vaccination rates among healthcare workers (HCWs) vary by country, region, and year. We investigated the influenza vaccination rates for HCWs during the 2017-2018 influenza season in South Korea, where a non-mandatory vaccination campaign was conducted. Methods: We retrospectively investigated factors affecting the influenza vaccination rate among HCWs during the 2017-2018 influenza season in three tertiary hospitals in Goyang City, where the non-mandatory influenza vaccination program is conducted. Results: Consequently, 6,994 of 7,180 HCWs (97%) were included, and the overall vaccination rate was 85%. Nurses had the highest rate with 92%, followed by health technicians (88%), physicians (84%), and non-medical HCWs (79%, P<0.001). Vaccination rates differed, depending on the frequency of contact with patients in the non-medical HCWs (frequent contact vs. less-frequent contact; 90% vs. 73%, P<0.001). Conclusions: The influenza vaccination rate among HCWs during the 2017-2018 influenza season in Korea was 85%, which is among the highest rates compared with previously reported non-mandatory vaccination rates in other countries. The vaccination rate may vary depending on the HCW's occupational characteristics, including the extent of contact with the patient. Therefore, a multifaceted strategy is needed to increase the vaccination rate of HCWs.

This is the study of efficient security system for candidates for the 17th President. The president election will be held in 20 countries this year. As conflicts between interest groups are expected to emerge, they are afraid of accidental raid in the campaign tour in addition to revival of regionalism and possibility of confrontation between interest groups with issues of anti-FTA In our country. The purpose of this study is to suggest appropriate method through study of security system for president candidate as just 6 months are left for the 17th president election. Also this study covers security environment for the president election, principle of security, and theoretical study for cause of terror, security system domestic and abroad and its analysis and how to provide the efficient security for president candidate. Therefore first, for desirable security the security should be provided by professional org like president security department. Second, combined security for target by current rules should be done. Fourth, total security is necessary to prevent security threats in advance. Third, the public security should be provided for every president candidates. Fifth, example of secret service in America should be studied and economical security should be considered Sixth, we should increase the use of Security Company and martial artists.

This study is focused on forecasting the future of tole-democracy. Many Scholars expect that internet provides technological space needing realizing the tole-democracy or deliberate democracy. Especially in Korea, this expectation is higher than other nations because of political corruption and inefficiency. Therefore internet is intended to considering as new technologies reforming political process. In 16th the general election period, many candidates established home page and used as election campaign tool. And a little of home pages is payed attention to among voters. In spite of using internet as political medium, many political communication researchers have a doubt that internet will realize ideal direct democracy. It's reason is that internet is open and anonymous space. At anonymous space, communication participators is tended to be irresponsible and non-serious. Therefore it is hard that cyber-politics will be ideal type of democracy. In this context, this paper analyzed how pauicipators communicate with others at cyber bulletin board establishing candidate's home pages. Main research questions is how do discussions at cyberspace fulfill the conditions of deliberate democracy. Therefore, concrete questions include; who are participators at candidate's cyber bulletin board; which pattern do they communicate; what is the theme of communication; which effects do the anonymous character of cyberspace influence. To that purpose, this study conducted content analysis on 4,210 written matters at 82 cyber bulletin boards of candidate's home page establishing during 16th the general election period. It can be found that cyberspace in Korea still is not deliberate democracy space and not will be. Firstly, discussion patterns at cyber bulletin board is "candidate with supporters communication space. To be exact, it is said that candidate's home page is "the space of self-convincing among supporters." Secondly, the main themes of discussion are simple emotional expressions; "I support you!" "fighting" "Be vigor" etc. By contrast, real political contents'-central or local political matters - is relatively few. In the mode of expression, real political messages are more positive, logical than simple expressions, candidates private matters. Especially this characteristic will make cyberspace as "mutual slander space" consolidating anonymous characteristic of cyberspace. finally, Cyberspace in Korea still is not real "public sphere" realizing deliberate process. Therefore to be real public sphere, it is needed to participant's ethical maturity and political citizenship. In conclusion, it is difficult that cyberspace will reconstruct the Athene's Agora. On the contrary, Cyberagora will like to be irrespectable area fulfilling the sweeping. Making the deliberate space, technological possibility and ethical condition will have to be balanced together.

I searched the recent murder cases for other criminal methods of homicides the monthly statistics of the local police agencies of the whole country, I found that there are many criminal cases where knives were used. Based on this finding, I decided to conduct my survey about kitchen knives. The statistics indicated more than five hundread male and female adults were reported to have committed murders. Of the 500 people, 21 used a kitchen knife to commit murder. This study showed that when people have a conflict, the kitchen knife is as a tool that can be easily changed into a weapon. If the points of the knife is round, more homicides could be avoided. If regulations were established, as we have with dagger when producing, selling or purchasing, I would assume that the number of the crimes with knives will be remarkably diminished. It is our responsibility to create a bill concerning regulatory standards in understanding the dangers of kitchen knives. We must immediately participate in active publicity campaigns.
