「Security Services Industry Act」made in 1976 for the purpose of contributing to the good operation of services industry by establishing the requirements for promotion, development and systematic management of services industry has been since 26 times of overall revisions. Period division of private security through overall revision of 「Security Services Industry Act」 can be roughly divided into three periods. The first is a settlement period. It is a period when the present five business areas were completed rom 1976 to 2001. Beginning with facility and escort security in 1996, five types of jobs have been prepared. so far by adding personal protection in 1996, and machine and special security in 2001. The second is a quantitative growth period. It is a period when quantitative development is made on the institutional basis. As various culture, sports and arts events are increasing based on the demand of security services due to an increase in the people's sense of security, quantitative development was made, which additionally influenced the downward trend of capital and the possibility of having two jobs through revisions. The third is a qualitative growth period. From 2013 to the present is a period when quantitative growth has slowed and qualitative growth has been made. After the period of quantitative growth, the growth slowed down. However, by raising the criteria for permission of services industry through creation of a rule for the group civil petition, by raising capital, by institutionally compensating for diverse punishment regulations, by realizing the training hours for new security guards, by permitting private education, etc, the reliability and professionality of a security guard job has been to be recovered.

Since the beginning of the millennium, 'Maker Movement' has been active throughout the world. Today, there is a maker fair every year in major cities of the world including Seoul, and the number of attendees is increasing day by day, so it can be seen as a kind of maker 'phenomenon'. The positive implication of the maker's movement is that it attempts to break down the monopoly of manufacturing and to restore the rights and capabilities of citizens as makers. Today, highly developed industrial capitalism has a tendency to structurally paralyse citizens, to tie their hands and feet, and to degenerate into consuming entities only. Therefore, it can be said that the maker movement has structural tensions in the relationship of neoliberal manufacturing culture. This study is an attempt to actively interpret the maker movement in terms of "critical making". The maker movement can trace its origins to "counterculture" and "new communalism" that emerged in the United States in the 1960s and 1970s. On the other hand, there is criticism that the maker movement can fall into another technology utopianism and function as an area of consumer society, and mobilize it in the direction of activating consumerism. Although the maker's movement is amorphous due to its characteristics and it is currently in progress, it is difficult to make crude definition yet. However, as the citizens who have been defined only as consumers of science and technology, are newly emerging as producers of makers, there have been great changes in the topography of science and technology and civil society. So the scientific implication of the maker movement is great in that it shows the possibility of causing it.

Optimum culture conditions and medium composition for hydrogen production by Clostridium beijerinckii KCTC 1785 were investigated. Initial pH and temperature for growth were 7.0 and $35^{\circ}C$, respectively. Agitation accelerated the hydrogen production. Although C. beijerinckii KCTC 1785 could grow up to 6%(w/v) glucose in the medium, the optimum glucose concentration for hydrogen production was 4% and hydrogen content in the biogas was 37%(v/v). However, the economical glucose concentration for hydrogen production was 1% regarding to the residual glucose which was not used in the medium. During hydrogen fermentation, acetic and butyric acid were produced simultaneously. High concentrations of acetic(>5,000 mg/L) or butyric(>3,000 mg/L) acid inhibited hydrogen production. When pH was maintained at 5.5 in the batch fermentation, 1,728 mL of hydrogen was produced from 0.5% glucose within 15 hr. $H_2$ yield was estimated to be 1.23 mol $H_2/mol$ glucose. It was found that yeast extract or tryptose in the medium was essential for hydrogen production.

This study is historical research on the relationship between the Changes of the Form of costume and the recognition of the beauty of the body from prehistorical period to Ch'ing Dynasty in Chinese female costume. In figure painting a significant point was to describe the spirit of the figure so Chinese painters were less interested in ideal body pro-portion or body shape than Westerns. But idealized beauty of the female body existed and changed keeping abreast with the form of costume in each period. In the prehistorical period Wemen fasten waist belt so enabled to distinguish upper part of the body from lower one. "Locust-forehead moth-eyebrows(蝗首蛾毛)" recorded in "the Book of odes(詩經)" was the canon of beaty and Wemen tried to make their forehead broad and square from Zhou Dynasty to the Wei Jin periods. From the age of Civil War to han Dynasty Slender waist was loved so waist was tightly fastened and hemline became broader. in the course of that time Plump body in big cloth with broad sleeve emerged but that was less significant than Tang Dynasty. During Wei Jin and the Southern/Northern Dynasty undergo disruption and division they admired Taoist images. Loose fitting style with handkerchief hemline and broad sash belt was prevailed while miserable life was reflected gaunt face and lean body. Suk Dynasty also preferred a slim and long body silhouette. The style was presented extremely high waist line long and narrow sleeve slim and long skirt which expressed dynamic and straight image. The culture of Tang Dynasty was open and diverse and that character enabled blod decolletate revealing body line by tight fitting and special make-up-Social background of uion and stabilization made female body extremely plump full face. full breast and hips with most erotic image. The period of Kaiyuan Tianbao fashioned mannish disguise presented androgynous image. Five Dynasty and Song Dynasty restored standard body type so upper garments concealed neck and bust high waist line lowered which represented refined and simple outfit. But another eroticism emerged as foot-binding in Song Dynasty. For the sake of covering up deformed top of the feet and ankle gaiters and arrow shaped shoes were devised. During Ming Ch'ing Dynasties body shape became more slim weak and young causing to escort instinct that reflects 'Lust' or 'Mundanity'.

In this study, anaerobic enrichment cultivation was performed with the sediments from the Gimpo and Inchon areas. Lactate as an electron donor and PCE as an electron acceptor was injected into the serum bottle with an anaerobic medium. After the incubation of 8 weeks, the reductive dechlorination of PCE was observed in 7 sites among 16 sites (43%). Three enrichment cultures showed completely dechlorination of PCE to ethene, while four enrichment culture showed transformation of PCE to cis-DCE. The bacterial community structure was analyzed by PCR-DGGE. Dechlorinating bacteria were detected by species-specific primers. The dominant species in seven anaerobic enrichments were found to belong to the genus of Dehalococcoides sp. and Geobacter sp., and Dehalobacter sp.

Coastal settlements have a diversity of tangible or intangible local assets and are environmentally sensitive areas. The value of tangible or intangible local assets is often overlooked and there is no enough consideration for the inhabitants who have a various and acute stake in the development process of coastal settlements. The development of coastal settlements without consideration for the local circumstance, resident's needs, and local characteristics makes it difficult to achieve sustainable regeneration. There are also alienation, conflicts, and the loss of a authentic sense of place because of physical oriented development without regard to the social, economic, and cultural aspects. This research defines the components and types of coastal settlements and draws the characteristics of them around the fishery ports in Busan in the aspect of sustainable regeneration. It will be the important methods for an integrated regeneration including not only spatial and physical regeneration but also social and economic regeneration which has the preservation of local culture with living conditions, local economy activation, and community building. It will also provides the bases of sustainable development, attractiveness, and competitiveness of coastal settlements.

1,4-Dioxane-degrading bacterial consortia were enriched from forest soil (FS) and activated sludge (AS) using a defined medium containing 1,4-dioxane as the sole carbon source. These two enrichments cultures appeared to have inducible tetrahydrofuran/dioxane and propane degradation enzymes. According to qPCR results on the 16S rRNA and soluble di-iron monooxygenase genes, the relative abundances of 1,4-dioxane-degrading bacteria to total bacteria in FS and AS were 29.4% and 57.8%, respectively. For FS, the cell growth yields (Y), maximum specific degradation rate ($V_{max}$), and half-saturation concentration ($K_m$) were 0.58 mg-protein/mg-dioxane, $0.037mg-dioxane/mg-protein{\cdot}h$, and 93.9 mg/l, respectively. For AS, Y, $V_{max}$, and $K_m$ were 0.34 mg-protein/mg-dioxane, $0.078mg-dioxane/mg-protein{\cdot}h$, and 181.3 mg/l, respectively. These kinetics data of FS and AS were similar to previously reported values. Based on bacterial community analysis on 16S rRNA gene sequences of the two enrichment cultures, the FS consortium was identified to contain 38.3% of Mycobacterium and 10.6% of Afipia, similar to previously reported literature. Meanwhile, 49.5% of the AS consortium belonged to the candidate division TM7, which has never been reported to be involved in 1,4-dioxane biodegradation. However, recent studies suggested that TM7 bacteria were associated with degradation of non-biodegradable and hazardous materials. Therefore, our results showed that previously unknown 1,4-dioxane-degrading bacteria might play an important role in enriched AS. Although the metabolic capability and ecophysiological significance of the predominant TM7 bacteria in AS enrichment culture remain unclear, our data reveal hidden characteristics of the TM7 phylum and provide a perspective for studying this previously uncultured phylotype.

The purpose of this paper is to describe the Disaster Management System Development of Enterprise GIS at the Kangwon Province in Korea. This project is included into 'the Kangwon Enterprise GIS 21 plan'. The Division of Disaster Management is in the middle of the 2-year project of the Disaster Management System development, appropriate for business performed at the Departments of Forestry, Culture, Environment, Tourism, etc. At the 1st phase of CIS implementation, for more than half a year we focused on the necessity of management of disasters. In the planning process, we needed long-term information on the whole area of Kangwon. In the assessment and response processes, we needed real-time data from Korean Meteorological Administration and other agencies. All the above information was carefully studied and referred to. ESRI's new GIS technologies solve the natural hazard/disaster problems. For example, hazardous materials routing often needs to be found the least expensive path through a roadway network. In the circumstances given, we can choose the departure point and destination of the vehicle, which carries the materials. It's also possible to minimize overall risk and costs of disaster problems by making a plan of people and possessions evacuation from the disaster area in short time limits. We can meet all the above goals using the latest ESRI's technologies.

The purpose of the study is to suggest contents, and a range of a Nonnative Theory and a practice for overcoming a crisis of the Mass media. In order to achieve the purpose of the study, a limitation and implication of Social Responsibility Theory was looked into by investigating a Hutchins Report. Hutchins Report suggested the related points at moral duty and legal obligation in implementing mass media's Social Responsibility and Accountability, with relations in publics and community. However, within a view point of a lack of Accountability, Social Responsibility Theory limited responsibility to the realm of 'function', 'self-regulation' and 'self-ethics', In order to promote mass media's quality and serve to rehabilitate its reliability under the pluralistic media system, the contents of Social Responsibility and its scope should be suggested. Media Accountability is a starting point to draw out the contents and scope of Social Responsibility and also a valid democratic plan for mass media to 'social self-regulation' through the mutual communication with civil society. For future Social Responsibility and Media Accountability that is suitable for various mass media, and contents and a range should be defined.

Since unfair trading practices between participants in construction project are common, the government has enforced several policies and systems to prevent or minimize the unfair trading practices in construction industry. However, not much attention has been paid to figure out which policies or acts are working or not. This paper analyzed the effectiveness of the policies and acts which are being implemented to prevent unfair trading practices and provided several suggestions to improve the performance of those acts. Survey was conducted to industry experts to collect data regarding their perceptions on those policies and acts. Then the effectiveness of the policies and acts were analyzed in terms of their importance and performance through IPA (Importance-Performance Analysis) based on the survey result. It was found through IPA that execution related acts such as investigation, exposure, and punishment for unfair trading practice have shown low effectiveness in entire construction process and dispute arbitration and mediation related center operated by authority showed low performance too. To improve the effectiveness of those acts, dispute arbitration system improvement, investigation & reporting system consolidation and enhancement practical binding force of punishment and penalty were suggested. Most of all, rules and culture for fair trading should become more established in construction industry by preventing conflict among participants through active communication.
