The safety nature of construction industry differs from that of manufacturing sector. For instance, accident risk level dramatically varies at each phase of construction process. Korean Occupational and Health Safety Act has been regulated OHS expense and it contributed reducing accident risk and enhancing safety culture for many years. However, although current regulation guides to use OHS expense proportionate to construction progress, it still allows late use of the expense. This study was conducted for the purpose of presenting methods of estimating a step-by-step OHS expense rate required at each construction phase. In order to do provide proper OHS expense schedule, it analysed accident risk of each construction phase by sorting out 1439 cases of construction site fatality reports, and proposed a method of generating appropriate OHS expense scheme according to its construction work progress characteristics. Both linear and sigmoidal S-curve model were used for the analysis, and the latter generally requires earlier use of OHS expense. By comparing the estimated OHS expense use schedule with current criteria, more than 27%p early use of OHS expense is required for the prevention of accident.

This study analysed the components and characters of welfare rights through discussions of the concepts and types of universal rights, and discussions of human rights and citizenship rights. Welfare rights is claims rights which requires somewhat, and it is positive rights. And it is generally passive rights, but it contains collective participation rights which is active rights. The result of total discussions of rights, human rights, and citizenship rights led us to know the components and characters of welfare rights. Welfare rights contains social rights, economic rights, and cultural environmental rights. Social rights are composed of the right of social security, social welfare service, health, education, and residency. Economic rights are composed of the right of labor, intervension of labor market, job security, and capital control. cultural environmental rights are composed of the right of culture and environment. And welfare rights has several characters. First, it is natural rights which is bestowed on the citizens or people in modern civil societies. it is samely characterised as liberties and political rights. second, it has the same values like other rights such as lberties and political rights. Or it is more important, because it is necessary for other rights. Third, it is not the objective being which is constant, but it is changed, formed and constructed as total rights with human rights and citizenship rights. Fourth, it is truely rights, but is simultaniously accompanied by obligations. But the obligations is unconditional like as other rights. Endly, levels of welfare on the welfare rights must be modicum rather than minimum. The meaning of modicum level is uncertain, but it aims to the entire participation of peoples as citizen and social integration. And it has to aim to the prevention of heridity and continuity of inequality.

A bacterium, KJA-118 showing a strong chitinase activity, was isolated and identified as Bacillus cereus. The strain produced maximum level of chitinase, when grown aerobically at $30^{\circ}C$ for 4 days in basal broth containing 1% colloidal chitin in the initial pH adjusted to 6.0. Among various carbon sources such as crab shell powder, chitin powder, colloidal chitin, and R. solani mycelium, maximum chitinase activity was found in culture broth supplemented with R. solani mycelium. When KJA-118 was incubated with R. solani, the cell wall of the fungus was found to be completely destroyed. SDS-PAGE and active staining results revealed that KJA-118 produced three isoforms of chitinase with molecular weights of 68 kDa, 47 kDa, and 37 kDa. When the suspension of KJA-118 was treated to cucumber seedlings, reducing rate of damping-off caused by R. solani was about 28.1%.

The Bio Best Bacillus(B3) and Rotating Activated Bacillus Contactor(RABC) processes, in which Bacillus strains are predominating, are reported to remove nitrogen and phosphorus as well as organic matter effectively. Nevertheless the nutrient removal characteristics of the Bacillus strains have not been studied in detail so far. This study investigated the organic and nutrient removal by Bacillus strains, Bacillus megaterium(KCTC 3007), Paenibacillus polymyxa(KCTC 3627), and Bacillus sp. A12, C21, F12, and L1(isolated from a B3 process), by incubating the strains in 0.2% nutrient broth at $30^{\circ}C$. Burkholderia cepacia(KCTC 2966), a common activated sludge organism, was used as a reference species for comparison. Although the degradation rate was affected by the population sire, the specific removal rates of organic matter by Bacillus strains were greater by $2\sim5$ times than that of Burkholderia. In particular, the culture bottles inoculated with the endospores of Bacillus megaterium and Bacillus sp. C21, F12, and N12 showed significantly higher degradation rate than those of vegetative cells.

As it is known, during the Second World War Greece has fought on the side of the allies and the end of the war found the country on the winners' side. However, the struggle for authority right after 1945 was merciless and extremely difficult, as well as dangerous for the course of the country to the future. The political powers were divided between the legal authorities that were represented by the king and formed the exiled government on the one hand and the part of the resistance teams and the rebels of the left that had a soviet friendly direction on the other. Thus, the start of a civil war was just a matter of time. It fin ally started in 1947 and lasted for more than two years. The consequences were disastrous for the country's economy and decisive for the future course of Greece. The national army prevailed with the help of, mostly, the English. Royal parliamentary democracy was established with a clear political turn to the west, as a completion and adaptation of the Agreement of the Great Powers at Yalta. Art had a 'similar' route. Dipolar, contradictory: conservative choices on the one side, and a will for pioneering inspiration and perspective on the other side. The 'dominate' trend was first evident in sculpture and mainly in the public monuments. Their construction aimed mostly at the public propaganda and at the promotion of the sovereign ideology. On the one side we have the public sculptures composed of faces of contemporary heroes or leading figures of the civic war and the national resistance. On the other side we have monumental statues mainly that appeal to a 'public' outside of the country's borders and mostly of the north borders, where there are countries with a communistic regime, like Bulgaria, Serbia and Albania. Their subject is derived from the heroic events of the Balkan Wars (1912-1913) and ancient historical figures like Alexander the Great as the Greek army leader, his father, Philippos II and Aristotle, who was of a north-Greek origin. The political message is twofold: on the one side the 'inner enemy' the communists that were defeated and the promotion of the new liberal social system and on the other side the north neighbours, which not only represent the East Block, but they also conspire the history and the culture of the Greeks. This is the way how the 'Cold War' was resulted in a full and totalitarian expression in art.

The World Summit on the Information Society (WSIS) was held in two phases. The first phase took place in Geneva, December 2003, and the second phase took place in Tunis, November 2005. The objective of the WSIS was to establish the foundations for an Information Society for all, reflecting all the different interests at stake. In relation to, this article explore the vision and paradigm of WSIS. For this, this article review the historical context of International information order and International agreements, and examine the issues of WSIS. As a result, I recognize, It is valuable that the process of WSIS for Global governance was held among governments and other stakeholders, i.e. the private sector, civil society and international organization. In addition, developing countries's voice are deeply reflected on the WSIS. It is noticeable that ITU played key role as coordinator. However, we are anxious that WSIS's vision for Information society have a bias toward Technology determinism. Eventually, this article argue that WSIS discourse is the lack of any serious and critical structural analysis of the politico-economic context.

With the expansion of corporate influence on civil society, companies are facing various demands and expectations on higher social responsibilities. This study discusses the influence of corporate social responsibility(CSR) on job attitude of employees when they recognize their company's CSR efforts. In this regard, it focuses on mediator effect of organizational identity by examining job satisfaction, organizational commitment, and turnover intention. Based on empirical investigation, positive influence was confirmed, stemming from recognized CSR. It influenced organizational identity, and it changed job attitudes including job satisfaction, organizational commitment, and decline of turnover intention. This result shows that if employees recognize company's sincere CSR activities and organizational values and culture are desirable, they tend to more strongly identify themselves with their organization. In sum, this paper found that organizational identity can be applied as a mediator which enhances the influence of CSR on job attitude. Lastly, it analyzed applicable implications to business management and suggestions for future research.

An efficient pilot scale (10 ton) three-stage methane fermentation system to digest food waste has been developed in this laboratory. This system consisted of three stages: semianaerobic hydrolysis, anaerobic acidogenesis and strictly anaerobic methanogenesis. From the secondary acidogenesis reactor, a novel strain KA4 responsible for alcohol fermentation was isolated and characterized. The cell was oval and its dimension was $5.5-6.5{\times}3.5-4.5\;{\mu}m$. This strain was identified as Saccharomyces cerevisiae KA4 by 26S rDNA D1/D2 rDNA sequence. Optimal culture temperature was $30-35^{\circ}C$. Cells were tolerant to 5% (v/v) ethanol concentration, however, were inhibited significantly by higher ethanol concentration up to 7%. The strain could grow well up to 50% (w/v) initial glucose concentration in the YM liquid medium, however, optimal concentration for ethanol fermentation was 10%. It could produce ethanol in a broad initial pH range from 4 to 10, and optimal pH was 6. In this condition, the strain converted 10% glucose to 7.4% ethanol during 24 hr, and ethanol yield was estimated to be 2.87 moi EtOH/mol glucose.

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.

Our society witnesses the rapid progress in the areas of politics, economy, society and culture in the process of national modernization since 1960s, which in turn as a reverse function gets to contract a societic pathology, totally lowering the security level of citizens' lives owing to various violent crimes like hostage commotions and murders with rifles and deadly weapons. what is the main reason for that? That may be partly because the chief police force concentrates on the current situation resulting in the vacuum of the public peace. However, the main reason is that the police fall short of man-power and equipments even if the whole police power were put to use in preventing and quelling the crimes. That is true not only of Korea but also of the advanced countries like the U.S.A., England and Japan. We realize that these advanced countries have higher level of security in every individual's life and property than Korea because their progress of the private guard systems can fill in a vacuum of the shortage of the police power, Therefore, we should without delay internationalize our private guard systems expecting the widely opening of the guard service markets in the age of Uruguay Round. To do this, we need to change our ideas for fostering the policy of the private guard from passive defense ideas into positive aggressive ones. Our police should urgently set up a plan to pursue the orientation of vision that we should dispatch our private guards overseas before foreign guards rush into our markets. Accordingly it goes without saying that the private guard group should distinguish their services from the public services initiating their own theory and strategy of private guard services and also readjust themselves between the public duties and the private services with the study of minimizing the reverse function of the private guard systems. The history criminal justice has always shown that the criminal system progressed at the initiative of the civil factor in case its demand and supply do not make both ends meet. Nevertheless, in the process the power of the government never weakens, rather it is built up in general. In conclusion, the necessity of the build-up of the private guard services must duly be acknowledged by the police as well as by the business which has its unique sphere within the criminal justice instead of as the suplemtary services of the simple the police power on the long-term basis. The purpose of the private guard services can be largely classified into the two categories; first it means the function to prevent the crimes against the citizens and secondly to enhance the national interest as an increasing mammoth business with a worldly competition capacity. The police has an absolute responsibility that they should protect the modem public in general from feeling the crisis of the personal threat, tension, anxiety and nervousness. In short, if we develop the complete private guard system to guarantee the societic atmosphere for all citizens, keep the public peace, and protect all citizens' lives and properties, we will sure enjoy a beautiful land, a wholesome society and a happy life in goodharmony of law and order.
