In Korea, measures to maintain sustainable fire safety performance for apartment buildings are insufficient in terms of fire-fighting products, skilled personnel, and maintenance status. Also, because of the particular features of a fire compartment, it has structural problems that are very likely to cause damage to human life when a fire occurs. Currently, problems with the fire supervisory system installed in an apartment building cannot be checked in real time, so it is difficult to identify the location of a fire accurately. Protected areas are also not assigned to each household, and residents cannot be clearly informed of the occurrence of a fire. As a consequence, safety evacuation cannot be secured. In addition, it is impossible to test the operation performance for water detectors in sprinkler fire extinguishing systems outside of the household. Therefore, an experiment was conducted to evaluate the performance of a remote fire supervisory system. The results show that the system satisfies all performance requirements. Also, an household alarm system was installed in each household to alert of any occurrence of a fire accurately, and the performance of the alarm system was improved to ensure that residents were quickly evacuated.

This research investigates the historical changes of the educational system for the clothing departments at vocational high schools. According to the growth of the fashion industry, employment potential in the clothing departments of the vocational high schools, numerical changes in the educational statistics, and curriculums were investigated by papers, reports, and statistic data. The statistic data were derived from the 'Center Educational Statistics and Information', 'School Information' (Hak-gyo Alimi), 'Korean Statistical Information Services' and internet home pages of vocational high schools. Technical service workers that graduate from clothing departments and vocational high schools have limited competitiveness in a thriving fashion industry field. Highly developed fashion industries require more professional workers in fashion design, fashion marketing, and fashion materials. Compared to 1994, when 35 classes were conducted in 5 vocational high schools, 69 classes are now conducted at 15 schools. They have over 2,000 students and produce over 600 graduates. However, 222 credits of the $1^{st}$ curriculum in 1958 went down to 82 credits in the 2007 revised curriculum to complete the credits of clothing departments. The 15 courses of the 1st curriculum fell to 5 courses in the 2007 revised curriculum on the number of major subjects. It is a fundamental problem that major courses in clothing education have been excessively reduced despite the demand for of highly specialized workers in the fashion industry. In the view of operating conditions of those schools, there were several problems such as the wide gaps in the curriculum, limited equipment, the supply of teachers, and counseling on the choice of college or a career. In conclusion, the following measures are required: 1) the increase of complement credits in major subjects and renovation of curriculum, 2) national substantial support to change the social circumstance concerning vocational education and occupational consciousness, 3) operation of credit approving systems in universities and colleges for students that have completed the same courses at vocational high schools, 4) designing realistic programs for vocational education and cooperation systems with corporate enterprises.

In this study, we carried out a survey on the degree of recognition for the brand of the Korea Institute of Geoscience and Mineral Resources (KIGAM) to contribute to reestablishing the status and role of KIGAM as an institution that people proud of by effectively delivering KIGAM's various research activities and achievements to people. About 49.9% of external publics recognized that there was relevance between research achievements of geo-technology and national brand. On the contribution of research achievements of geo-technology to promoting Korea's power of science and technology, 42.3% gave positive answers. On research achievements of mineral resources technology, just 14.4% replied they saw such results. As alternatives to promote the degree of recognition for brand, we suggested development of beneficial message, operation of brand management committee, promotion of involvement of research achievements of mineral resources technology about people-friendly subjects, development and distribution of "board game for education on mineral resources technology" for youths, activation of location PR, activation of online Q&A bulletin board, finding out star researchers, and president's PI activities.

Recently, as new paradigm for government operation called government 3.0, government is actively operating policy opening and sharing public data. In addition, the Ministry of Land are operating an open platform integrated map service (the VWorld) which provides a variety of video contents such as the country's national spatial information, traffic information and three-dimensional building for the public. According to W3C Foundation's Open Data Status Report(2013), our country has the evaluated results that the part of the government's policy support and planning is good while the part of the data management is vulnerable. So our country needs the quality improvement for the data management. In addition, a digital aerial photograph image data is required to be up-to-date for the three-dimensional spatial object data. In this paper, we present the method for enhancement of the accuracy of vertical position and for maintainment of up-to-date vertical position. Our methods evaluate the data quality and analyze the cause of error of measurement utilizing the national standard quality assessment method. The result of research shows that the accuracy of vertical position is improved if the height of the building captain is adjusted by the quality assessment values and a three-dimensional model has up-to-date data if reconstruction and extension information of construction register is utilized.
This study closely analyzed the curriculum of the Christian Education Counseling Department and the general Education Counseling Department, and found the current status and problems of the curriculum of the Christian Education Counseling Department and the general Education Counsel Department. This study presented a balanced curriculum of the Christian Education Counseling Department with above analysis. For this purpose, the analysis focused on the educational operation process of Christian education counseling departments and general education counseling departments, such as educational goals, subjects, and counseling practical training. The Christian Education Counseling Department and the general Education Counseling Department are often combined with departments such as Christian Education, Youth, Children and Youth, and Lifelong Education, with the characteristics of convergence majors, so the basic subjects of the department were analyzed to have a higher percentage of subjects than counseling subjects. The results of the analysis showed that both departments lacked a considerable number of subjects related to counseling practical training. In the counseling course, the subjects of personal analysis, education analysis, counseling ethics, and counseling case super-vision for the professional development of counselors are still lacking, according to the analysis. In order to train counselors, it was analyzed that the system of systematic clinical practice system, various counseling analysis for counselor education, and the expansion of super vision subjects were urgently needed. In a modern society where the demand for counseling and the need for counseling experts are increasing as society becomes more complex, it is hoped that Korean universities will be able to actively contribute and cooperate in developing models of counseling education and training counseling experts through them, focusing on standardized indicators for fostering counselors.
In this study, the problems in the domestic disaster management system were identified through the examination of the system, relevant implications were drawn through the present status of domestic integrated disaster management system, and the consciousness survey for the integrated disaster management system targeting fire-fighting officers in the front line of the disaster was carried out to identify the measures to improve the system. Based on the findings, the measures to establish and revitalize the integrated disaster management system was presented, and the contents of the measures are as follows. In order to establish and revitalize the integrated disaster management system, the following measures should be prepared for each item. In the organizational aspect, the coordination system between government agencies should be established properly and the relevant information should he shared and delivered smoothly. In the legal and institutional aspect, the improvement is required to prevent any miscommunications in the coordination and joint operation plan through the collaboration between government agencies should be established in consideration of characteristics of each government agency. Also, in the aspect of system, the equipment should be maintained and updated continuously in order to respond to rapidly changing disasters and the organization, laws, institutions and system should be improved systematically and harmoniously. And, the detailed measures appropriate for the characteristics of domestic disasters should be prepared through the examination of advantages and disadvantages of integrated disaster management system in advanced countries in details and the detailed plans for the establishment of integrated situation management system in relevant organizations and the unification of situation room through the establishment of efficient integrated management system should be established.

In Gyeonggi-do(province), where the largest number of small libraries are located in Korea, 42% of small libraries are located in apartment complexes. However, as libraries established under legal obligations are managed and operated on voluntary will, there have been numerous ongoing cases of temporary closure or permanent shut down. To revitalize small libraries in apartment complexes, it is reasonable to seek ways to revitalize them through the role of the central point of the village community in the complex. To that end, this study surveyed the current status of small libraries in Gyeonggi-do, a survey of small library operators and related persons in apartment housing complexes and similar residential communities in Gyeonggi-do and 31 cities and counties. Based on this, this study was intended to derive practical measures to revitalize the operation and preservation of small libraries in such residential communities. Four goals were set to improve community awareness of small libraries, cultivate self-operating abilities, improve laws and systems, and strengthen support for local governments. Research needs to be carried out not only for small libraries in apartment complexes in Gyeonggi-do but also for the continued development of other small private libraries.

Video streaming over wireless multi-hop networks(WMNs) contains the following challenges from channel fading and variable bandwidth of wireless channel, and it cause degradation of video streaming performance. To overcome the challenges, currently, WMNs can use Forward Error Correction (FEC) mechanism. In WMNs, traditional FEC schemes, E2E-FEC and HbH-FEC, for video streaming are applied, but it has long transmission delay, high computational complexity and inefficient usage of resource. Also, to distinguish network status in streaming path, it has limitation. In this paper, we propose monitoring-based coordination of network-adaptive hop-to-end(H2E) FEC scheme. To enable proposed scheme, we apply a centralized coordinator. The coordinator has observing overall monitoring information and coordinating H2E-FEC mechanism. Main points of H2E-FEC is distinguishing operation range as well as selecting FEC starting node and redundancy from monitored results in coordination. To verify the proposed scheme, we perform extensive experiment over the OMF(Orbit Measurement Framework) and IEEE 802.1la-based multi-hop WMN testbed, and we carry out performance improvement, 17%, from performance comparison by existing FEC scheme.

this study, an expert AHP questionnaire analysis of public and private groups was conducted to take into consideration the requirements for realistic disaster services. Considered are public areas that manage disasters like fires and earthquakes that can be a major threat to national safety, as well as private areas that mainly develop disaster-related technologies. In the questionnaire, the public respondents valued accurate disaster situation information (ranked 4th and 6th) for citizens (1st), managers (3rd), and related organizations (2nd); the private sector highly valued the importance of three-dimensional (3D) control (ranked 1st, 3rd, and 5th) using future technologies. This study suggests the realization of a disaster-response service that meets the needs of public safety and technological innovation based on a 3D safety state information platform. We anticipate that this study will provide useful data for applying technology and for establishing detailed scenarios during the test bed and commercialization phases. We also expect that further studies will be conducted, such as the practical application and operation of realistic disaster response services, on the financial resources for the proliferation of local governments, and on policy support measures.
Phosphorus (P) is an essential and irreplaceable element for all living organisms, and it is widely used as a fertilizer. Unfortunately, it is estimated that phosphate reservoir is depleted within about 100 years. Sewage sludge ash (SSA) is an alternative resource for P recovery because of its high P content. However, SSA cannot be directly used as a fertilizer due to heavy metals in it and low P bioavailability. Thermochemical treatment with Cl donor is known to reduce heavy metal contents and increase P bioavailability of SSA. Literature review on thermochemical technologies of SSA for the reduction of heavy metals and bioavailability enhancement has been carried out to estimate the status of current P recovery technology and to develop strategic future research plan for P recovery. The review showed that $CaCl_2$ and $MgCl_2$ were the most effective Cl donors and reaction temperature (< $1000^{\circ}C$) was the critical operation condition for the reduction. The removal efficiency depends on the species of heavy metals. Thermochemical technology of SSA for P recovery showed the possibility of commercial application in the near future to overcome the coming crisis of human sustainability by P depletion, but it needs cost effectiveness and more ecofriendly process to reduce energy consumption.
