As the demand for national security and national safety is gradually increasing in accordance with the trend of the times and social environment, and the use of private areas for effective prevention and supply required for the demand for safety services, this paper analyzed the Japanese private security testing system for the introduction of the Korea security certification system as a way to secure expertise in the private security industry and drew the following conclusion. First, certificate segmentation should be carried out according to the clearly divided field and scope of the expense operation. Second, it is necessary to distinguish the qualification of the private security qualification according to the level. Third, it is necessary to utilize the combined evaluation method through the departmental and practical tests. Fourth, an assessment should be made through the link between departments and practical subjects. Fifth, the diversity of the acquisition methods should be placed to ensure the gainer's accessibility. Finally, the use of professional and visible use of professional personnel should be achieved through benefit assessment for those who are qualified for

In 1997, 180 countries signed the Kyoto Protocol in Kyoto, Japan. The Kyoto Protocol came into force in February 2005. The agreement calls for industrialized nations to cut greenhouse gas emissions by 5 percent from 1990 levels by 2008 to 2012. One of those polices is a modal shift that change from road freight to sea, inland waterway and railroad transportation that is eco-friendly. The increase of road freight brings road congestion, accidents, logistic costs, air pollution and greenhouse gases. Railroads are superior than the other modes of transportation in mass transportability, high speed, timeliness, safety and environmental-friendliness, but the railway industry has been pushed behind in competition. Korean railroads were used by passengers and freight transport popularly until the middle of 20th century, however, by the sudden change of logistics environments, a shaving time efficiency being most important, railroad logistic lost its competitive power against the transportation by truck. From the research which sees consequently investigated a various policy, a system and a law about Chinese logistics industry and present condition of the Chinese goods enterprise and instance analysis of the large Chinese corporation that branch out to undeveloped markets led and a Chinese logistics industry and problem point escape hereafter the heightening of competitiveness plan which is rational under prsenting boil.

The purpose of this study is to investigate the ecosystem structure underlying the development of artificial intelligence technology and related industries. In addition, the research on the AI business ecosystem based on AI technology and the ways to activate them was discussed. Ecosystems play a role in organically connecting producers, consumers, and decomposers. In the AI ecosystem, we classified the AI service producers, producers of AI services using the produced services, and data and related infrastructure services that are the basis of AI services. Stakeholders in the AI business ecosystem are the government and various private organizations that have a direct or indirect influence on AI service production, consumption, and operation. In Korea, in particular, the government plays a role as the most influential stakeholders. For example, the company contributes to the increase of producers, which are related to human resource development, and plays a catalyst role in the increase of services produced by R & D funding. In this study, the policy for revitalizing the AI business ecosystem includes (1) securing the environment for increasing producers, (2) spreading AI awareness among consumers, (3) securing data exchange and supply infrastructure, and (4) supporting services and related laws. Secure the system. This study is meaningful in that it contributes to and contributes to the construction of domestic AI-based environment and related research.

In a period of rapid change, transition and re-definition of care concept, this study reviewed social policies on care providers in the UK. In the face of care crisis, the British government has made a radical reform of the care system and enacted new legislations. In the UK social policy, care providers are classified into carers and care workers. Carers mean informal caregivers and care workers are those who are paid for providing care as part of a contract of employment. Recently, the United Kingdom has given carers recognition and reward. To enhance the status and right of carers, the Carers (Recognition and Services) Act 1995, the strategy document Caring about Carers 1999, Carers and Disabled Children Act 2000, and Carers (Equal Opportunities) Act 2004 have been enacted. At the heart of the policy for carers is the idea of active citizenship, carers-friendly employment and work-life balance etc. In case of paid care worker, government's focus seems to be on quality of employment. The government has established a new national infrastructure for quality. The five national bodies founded on Care Standards Act 2000 has been established. The UK government has realized care work would play an important part in job creation strategy. In this article, we have presented several criticisms and issues of current care policy in UK.

Nepal is a landlocked mountainous country in South Asia, located between China to the north and India to the south, east, and west. As such, wastewater management has become one of the most significant problems in urban area of Nepal. In Nepal, the centralized wastewater treatment systems were dysfunctional due to high cost of operation, discontinuous power supply, lack of proper maintenance and proper technical workforce to address the issues. As such, constructed wetlands (CW) were applied to treat various secondary wastewater as alternative to wastewater treatment facilities. Generally, efficiency and sustainability of CW technology depends on proper operation and maintenance and active community involvement. This study summarizes information about 26 CW in Nepal. Specifically, factors including data banking, removal efficiency, quality of discharged water, compliance to water quality standard of Nepal and operation and maintenance were investigated. Considering removal efficiency per pollutant, Ka-1 achieved the greatest reduction for most pollutant followed by B-1, L-3, Ka-5 and K-1. Nepal has practiced CW technology for more than 2 decades but currently, development of technology was interrupted by the inefficient performance of existing facilities. Public awareness about the technology, natural disaster, unavailability of specified substrate materials, lack of fund for further research and experiments has hindered the expansion of technology. In spite of these concerns, CW was still proven as an alternative solution to the present wastewater problems in urban areas of Nepal.

According to the government's smart factory promotion project for small and medium-sized enterprises, more than 10,000 intelligent factories are scheduled or already built in the country and the government-led goal is to nurture 100,000 skilled workers by 2022. Smart Factory introduces numerous types of education and training courses from the supplier's point of view, such as training institutions belonging to local governments, some universities, and public organizations, in the form of an efficient resource management system and ICT technology convergence in the automated manufacturing equipment. The lack of linkage with the NCS, the standard for training, seems to have room for rethinking and direction. Results of survey is provided for the family companies of K-University in the metropolitan area and Chungnam area, and analyzes job demands by identifying whether or not they want to introduce smart factories. Defining the practitioners who will serve as a window for the introduction of smart factory technology within the company, setting up a training goal in consideration of the career path, and including the level of training required competency units, optional competency units, and training time suitable for introducing and operating smart factories. Author would like to present an NCS-based qualification design plan.

BACKGROUND: Burcucumber(Sicyos angulatus L.) is an invasive plant species and disturbs ecosystems in Korea. The main method for prevention of burcucumber is cutting or pulling out. However, the studies accounting for the use of the by-product of burcucumber after cutting remain incomplete. Thus, the aim of this study was to investigate the applicability of burcucumber as a substitute for nitrogen fertilizer.METHODS AND RESULTS: Burcucmber plants only including stem, leaves, and petiole were collected from the Sky Park in Seoul and divided in to three categories based on the length of stem of burcucumber; 10-30 cm, 30-100 cm, and 100-200 cm. And they were input into soil with 20 kg-N/10 a. After 4 weeks aging, chemical properties of treated soils and the productivity of lettuce(Lactuca sativa L.) were examined. Both the inorganic nitrogen contents in soils and the growth of lettuce were increased with the decreases in length of burcucumber standing for young plant. And the inorganic nitrogen content and the productivity of lettuce were positively correlated(r= 0.9409).CONCLUSION: The C/N ratio of burcucumber was low, indicating fast decomposition and nitrogen supplying rate, resulting in the increase in lettuce growth. Burcucumber could be a good substitute for nitrogen organic fertilizer.

This study is to establish a national vision of the hydrogen economy and design a roadmap to materialize it. A goal is set to supply 15% of final energy consumption with hydrogen energy in Korea by 2040. Selecting the transportation sorter as the main target, more than 50% of vehicles on the road will be replaced with fuel cell vehicles (FCVs) while $20{\sim}30%$ of electricity demand in the residential and commercial sectors might be replaced with power generation by fuel cells. If this goals were attained as planned, primary energy demand would be reduced by 9%, resulting in improved energy mix in which fossil fuel consumption is greatly reduced whereas renewable energy increases by 47%. Furthermore, GHG emissions will be reduced by 20% and self-sufficiency in energy is enhanced up to 23%. If the hydrogen economy is to materialize, the government needs to implement institutional arrangements such as new legislations, organizations, and fiscal measures to facilitate the process. In addition, the private sector's participation is highly recommended to mobilize fund needed for the huge investment to build an infrastructure in preparation for the hydrogen economy. Arrangements for codes and standards are also required to promote industrialization of fuel cells and hydrogen production and consumption.

In Korea, the Emergency Medical Service, EMS is provided by Fire Services with 119 EMS and all the public uses the service for free. Although it appears very successful and is respected nationally, structural problem EMS exist and are worsening. First of all, the "free riding effect" becomes increasingly problematic. Some argue that 30% of the demands is not urgent or emergent. The total number of demands is increasing even without the free riding effect. The Current EMS system itself cannot meet the increasing EMS demand. The medical aspect is so poor that the EMS cannot dispatch a medical specialist to the scene. The cardiac arrest resuscitation rate is only $1.24{\sim}9.9%$, compared to 40% in Boston, MA, USA. But due to the regulations and limitations of the Fire Service organization, it is difficult to secure enough EMS resources. To work out these problems, it needs a structural innovation. To secure enough resources and achieve higher medical performance we should invite the medical sector and the private sector into EMS arena by contracting partnerships with Fire Services and charging a reasonable EMS fee. We found through statistical test that any partnership system is more effective than fire-alone system and most countries around the world have partnership system rather than fire-alone system.

As the current level of birth rate of Korea has dramatically declined, it is obvious that pediatric dentistry will also be affected by this change. This study was performed for the purpose of understanding on the current fertility levels of Korea. The formal data on the number of live births(NLB), crude birth rate(CBR), and total fertility rate(TFR) published annually from the National Statistical Office of Korea from 1992 to 2000 were used as materials for this study. The TFR values from 1990 to 2002 of Korea were compared with those of some western countries with similar history of decreased birth and the CBR values of the metropolitan cities and the capital city Seoul in 2003 were compared domestically, yielding to results as follows. 1. Recent birth rate of Korea was decreased continuously. NLB was about 490,000 CBR was 10.2 and TFR was 1.19. 2. TFR of Korea in 2002 was 1.17, the lowest in the world. 3. There was a large difference in the NLB and CBR between local prefectures and towns of Seoul domestically. Additional population studies and medico-economical studies to exactly predict the demands of pediatric dentistry and proper supplies of manpower in the future was thought urgently required.
