  • Accurate assessment of greenhouse gas emissions is a cornerstone of every climate change response study, and reliable assessment of greenhouse gas emission data is being used as a practical basis for the entire climate change prediction and modeling studies. Essential, fundamental technologies for estimating greenhouse gas emissions include an on-site monitoring technology, an evaluation methodology of uncertainty in emission factors, and a verification technology for reductions. The closed chamber method is being commonly used to measure gas fluxes between soil-vegetation and atmosphere. This method has the advantages of being simple, easily available and economical. This study presented the technical bases of the closed chamber method for measuring methane fluxes from a rice paddy. The methane fluxes from rice paddies occupy the largest portion of a single source of greenhouse gas in the agricultural field. We reviewed the international and the domestic studies on automated chamber monitoring systems that have been developed from manually operated chambers. Based on this review, we discussed scientific concerns on chamber methods with a particular focus on quality control for improving measurement reliability of field data.

  • This study found that it is critical to consider farmers' intention to adopt new technology in order to facilitate the spread of new technology. Based on this assumption, the research team analyzed the following: factors that influence intention of adoption and marginal effects on those factors. The data were collected from 99 farmers who did not participate in the pilot projects on dissemination of new technologies developed by the Rural Development Administration (RDA). A total of 19 observed variables were set to measure seven latent variables: educational support; technical support; funding support; compatibility; trialability; observability; and antipathy. The intention to adopt new technology was established as the dependent variable. According to the ordered logit analysis, educational support, observability, and antipathy were found to have significantly affected the intention to adopt new technology; their odds ratio were 6.938, 2.716, and 0.501, respectively. According to the marginal analysis, educational support, observability, and antipathy were found to have significantly affected the intention to adopt new technology; their marginal effects were 20.2 %, 10.4 %, and -7.2 %, respectively. Therefore, this study suggests the following to facilitate the spread of new technology: first, provide quality support services through effective deduction; second, increase the visibility of new technology; and third, enhance the credibility of agricultural institutions by developing continuous relations with farmers to reduce their antipathy.

  • Many educational facilities have been formed due to the nation's revival policy in the animation industry since about 1995. Owed to the active financial support of the nation, the production industry rapidly vitalized, production technology rapidly advanced, and a large workforce is being passed on into society through educational institutions. The reality of many developing countries appearing to be putting emphasis on the industrialization of animation, similar to our country, is becoming a great pressure on us industrially. It is never easy to develop a certain field into a globally competitive industry in a short period of time. Our countermeasure, pursuant to these international circumstances, lies in innovation and creativity that has broken away from the existing methods of production, and mass production of high quality animation specialists. This paper is a new educational proposition for the consolidation of national competitiveness. Animating, the core of producing an animation, completely depends on the animator's artistic and technical ability. In order to supplement the existing methods of studying by theory and make up for the biggest weak point, which is the lack of "on the scene" learning contents, I propose incorporating movements based on frequently appearing characters in popular animations and acting them out slowly and including the "Slow Motion" kinetic effect, a way of enabling someone to learn and sense astrodynamic fundamental principles by oneself. It is a new method of learning movement, a plan made to achieve sensual performance gestures, and an improvement in direction for students who wish to become animators in the future.

  • In modern society, citizens' quality of life aspects of safety and crime prevention activities are actively considering the incidence of crime prevention in advance. It also can be quite important elicit the interest of who community members through effective crime prevention strategies. For crime prevention policies and techniques over time as more scientific and advanced methods are made. Today, A typical crime prevention strategies is private security zones and Crime Prevention Through Environmental Design (CPTED) is a corresponding to the new strategy. CPTED is a diversification can be called a crime prevention approach that emphasizes the principle of natural surveillance, access control, territoriality, activity support, maintenance and management. The defensible space of the space area related to crime prevention setting the activities of private security and CPTED determine. Also, the reality of crime prevention and protection should be considered space. The emphasis on proactive prevention of crime in modern society for the prevention of crime how to approach differing perspectives and disparate aspects of private security and CPTED. Technical and professional areas that overlap to some extent in a homogeneous aspect. Ultimately, CPTED is a crime prevention through space and environmental approach for crime. In addition, Ultimate goal of convergence, crime prevention, with the same or higher is required to study for the area after looking for the characteristics and limitations of private security and CPTED.

  • Lately, with the increase of the private security industry, individual quality improvement of the private security guards is rising. Especially, in accordance with competence of the private security guards, in the base of individual technical or knowledge, the confidence of own ability is essential for the improvement of the private security industry. In accordance with the private security guards, the study of their competence is rare. But through the study of teenagers or members of the public organization, we can know the influence of variables competence. The purpose of this study is to show how the self-esteem, need for Achievement, relation with co-worker and supervisor, and leadership effect on competence. Consequently this study will offer effective ways to develop the private security guards competence. We can show that self-esteem effects competence of the private security guards between the need for achievement and self-esteem which are adjusted as the individual characteristic. Namely, the higher the self-esteem of the private security guards is, the higher competence is. The study shows that the relation with co-worker and supervisor of the private security guards doesn't effect competence. Unlike the previous studies, this study proves that contingent reward has a positive effect on the Private Security Guards competence in the transactional leadership. That is, the higher the contingent reward of leader is, the higher the level of competence of the Private Security Guards is. Lastly, We can know individualized consideration effect the competence of the private security guards in the transformational leadership.

  • We, Tong Yang Moolsan Co. Ltd. (TYM) set up the mass-production system for virus-free seed garlic via tissue culture technique. TYM's tissue culture technique is called as 'Multiple shoot propagation technique' This technique can lead mass propagation of genetically homogeneous seed garlic in a short period because of its highly proliferation rate of in vitro shoots (15/sup 10//year). TYM researchers applied the technique to some selected garlic cultivars with superior characteristics and carried out field test of productivity in the inside and outside of the country for several years. According to the yearly results of field test with virus-free seed garlic, we ascertained that virus-free seed garlic can produce the highly yield increase (max. above 50%) and also can enhance the product quality. Consequently, we estimated that TYM's seed garlic will contribute to farmers with increase of income and can elevate the national position of garlic market in the world for its competitive power of technical and production cost.

  • For the purpose of protecting personal property and lives from incidents, accidents, and threats such as terrorism, video surveillance equipment has been installed and operates in many places. Video surveillance technology has gradually developed into high-quality, high-definition equipment, and a lot of products have been launched. However, closed circuit television (CCTV) equipment for security purposes can invade a person's privacy. In this paper, we propose a way to protect personal video images using meta-data in an intelligent Internet protocol (IP) camera. We designed the system to mask personal video information from meta-data, define the method of image-information access according to user privileges, and show how to utilize the meta-data during storage and recorded data searches. The suggested system complies with guidelines for CCTV installation and operation from Korea's Ministry of the Interior. Installed on only a single server so far, due to the limitations and technical difficulties of hardware performance, it has been difficult to find a method that can be applied to personal image information using real-time protection techniques. Applying the method proposed in this paper can satisfy the guidelines, reduce server costs, and reduce system complexity.

  • Despite the importance of the needs assessment activities and the necessity of the systematical investigation on the features of the needs assessment in the social service agencies, it has been observed that the recent NA studies have ignored an important study area of NA, the utilization of needs assessment results in social service agencies. Therefore, this study was undertaken to investigate salient features of the utilization of community needs assessment results, particularly, in the social welfare centers located in Seoul city. A questionnaire was constructed with seven parts, including a dependent variable and 6 independent variables, and 67 questionnaires were collected from 90 agencies during two months. As the result of the descriptive analyses, the five noticeable features were found; (1) the needs assessment results in the agencies was not highly utilized; (2) the attitude on the NA activities was not highly positive because the responders thought that NA activities require too much time from agency staff; (3) agency staff was more actively involved in the NA process than agency directors; (4) the responders thought that quality of NA influences on the utilization of NA; (5) the respondents were confident in carrying out NA although they did not have many opportunities to learn the technical skills of NA research. Multiple regressions were applied to analyze the relationship between independent variables and three kind of dependent variables - conceptual utilization, instrumental utilization, total utilization. The result showed that the conceptual utilization was critically influenced by social workers' confidence on NA, attitude on NA, and directors' involvement in NA. The institutional utilization was influenced by the directors' involvement. The total utilization was influenced by social workers' attitude on NA, confidence on NA, and directors's involvement. Major findings were discussed and several suggestions were made for future research and improvement of the utilization of needs assessment result in social welfare centers.

  • China's independent college approved private education investment, and facilitates the use of funds to support individual investors, corporations, and society. In contrast to China's public universities, the college guarantee private school method of operation. Its bachelor's degree, admission to students, the establishment of a separate corporation, and the recognition of scholastic achievements, was established with the aim of ensuring the diversity of higher education institutions in China. However, since the early 1990s, the independent college, which has emerged as a new way of higher education in China, has achieved quantitative growth over the past 30 years, but the quality of education has not yet grown. The reason why the independent college in China is interested is that it receives support from the facilities and professors of the original public college, and the major in which it is established and shares the reputation of the university. This study tried to analyze the policy of independent college which is a unique higher education institution in China. For this purpose, we use Four-Dimensional Framework to analyze the problem of China's independent colleges. It examines the profitability and non-profitability of independent college as a normative dimension and analyzes the Chinese society that have the old "guanxi" culture core in China. On the structural dimension, we analyzed the structure of the relationship in educational administrative institution. On the constituentive dimension, we observed that the various stakeholders who are interested in the independent college policy. Finally, we searched for future directions of the independent college centered on the process of legalization of independent colleges in technical dimension. The results of this analysis suggest the implications of the direction of China's independent college policy.
