Fire fighters should eat their meal very fast in order to arrive in the emergency scene on time. The purpose of the study is to investigate the influence of eating speed on the health of the fire fighters. The subjects were fire fighters, National maritime police, soldiers, public officials, university students, and company employees. The fire fighters had the shortest eating time of 8 minutes 29 seconds, and eating speed of National maritime police was 8 minutes 33.17 seconds, and public officials had 12 minutes 49.33 seconds. Soldiers had 10 minutes 15 seconds, university students had 14 minutes 15 seconds, and company employees had 16 minutes 51 seconds in eating their meals. The previous studies said that eating speed had influenced on the metabolic syndrome and the survey on the American fire fighters showed that the fire fighters gained 7.7 pounds during the past 8 years. Through this study, it is necessary to implement the right eating habit that is able to slow down the eating speed in the Korean fire fighters. The Fire Academy should provide the right eating habit education program to the fire fighters.

Currently the oriental medical care services in the health centers is getting popularity because of their unique aspects which western medicine can not cover. This study was conducted to speculate the current status of oriental medical care services in health centers and possibility of how to effectively provide the oriental medical care services(or traditional medical care services) in health centers. For the study, the survey questionnaires were distributed to all 269 health centers and 138(51.3%) of them were collected. Eight of the collected were inadequate for the analysis and 130 of 269 questionnaires were finally chosen for the study. The SPSS/PC WIN 8.0 was used for the statistical analysis. The results are as follows. First, 91 out of 130 sample health centers(70%) are providing oriental medical care services. The results show that the willingness of the directors and the public awareness in community are the most important factors to provide oriental medical care services in health centers. In contrast, the lack of cooperative efforts between western and oriental medical doctors and the lack of government supports are considered as factors that intervene the oriental medical care services in health centers. About 80% of the sample health centers respond that the government supports is needed for oriental medical care services in health centers. Second, it was asked to the directors of 39 health centers which do not provide oriental medical care services regarding their future plan to include the services. About 70% of health centers respond that no plan is available now. They acknowledge that the demand on the services is the most important factor to consider the oriental services as their future medical services. Third, 69.2% of the oriental medical doctors in health centers are public health doctor. 95.6% of the sample health centers have space for the oriental medical care services in their facilities and some health centers provide the services through the private clinics nearby facilities. Finally, the surveyors consider both budgetary constraints and difficulty in recruiting doctors as barriers for the effective oriental medical care services in health centers. Finally, t-test and LSD were employed to find out the difference among several groups. The analysis shows statistically significant difference among groups about their recognition on health care policy, health care system, and effectiveness of oriental medical care services. To be conclude, the study shows the necessity of oriental medical care services in health centers. To do so, the government supports, cooperative efforts between oriental and western medical doctors, and providing job security for doctors should proceed to provide effective oriental medical care services in health centers.

Road facilities with a service life of more than 30 years are expected to triple in the next ten years. The seismic performance of road facilities should be reviewed with consideration of the "Common Application of Seismic Design Standards" issued by Korea's Ministry of Public Administration and Security in 2017. These standards should be applied to all existing road facilities, including retrofitted or seismic-designed facilities, for evaluating seismic performance. In order to manage seismic performance for a large number of facilities, decision-support technology that can provide economic and reliable results is needed. However, the indices method currently used in Korea is a deterministic method, and the seismic performance of individual facilities is evaluated based on qualitative indices so that only retrofitting among road facilities is prioritized. In turn, with the indices method, it is difficult to support decisions other than the decision to prioritize retrofitting. Therefore, it is necessary to use the seismic risk assessment method to overcome such shortcomings and provide useful information such as direct loss, indirect socio-economic loss, and benefit of the investment.

The 'NIST Framework and Road Map for Smart Grid Interoperability Standards' proposes an architecture framework to secure the direction of development and standard interoperability of smart grid and provides a list of identified standard, standard cyber security strategies, and certification framework. In particular, SEP 2.0 and OpenADR 2.0 are the examples. SEP 2.0 and OpenADR 2.0 can functionally link HEMS and Smart Grid, but interoperability standards between the two protocols are not planned in above document. The OpenADR Alliance also announced that work is underway to define mapping tables for interoperability between OpenADR 2.0 and SEP 2.0, but no information is yet available. Therefore, In this paper, in developing energy efficiency improvement HEMS, we propose a mapping model that supports syntactic and semantic founded interoperability between SEP 2.0 and OpenADR 2.0b for ICT grid convergence based on the standard specification document of each protocol and confirmed through an example of the semantic mapping function based on the demand response service scenario.

Purpose - The Northeast Asian Logistic Hub strategy was established to create a national competitive advantage in northeast Asia. Countries in this region are competing fiercely to become the central base distribution port as the volume of container shipping continues to increase due to the northeast Asian (especially Chinese) economic growth. The primary method by which shippers are improving their customer service and distribution is enhancing profits by minimizing call ports on the key route through strategic affiliations and the use of large vessels. Each nation is planning large-scale investments in the construction of sea ports that can accommodate large vessels. This paper proposes ways by which the logistical strategies of domestic corporations can keep pace with changes in government policy concerning the Northeast Asian Business Hub policy. It examines the logistics system in the Northeast Asian region, analyzes the government's Northeast Asian Business Hub policy, and suggests logistical strategies for domestic corporations through an analysis based on a questionnaire designed to grasp domestic firms' needs and goals. Research design, data and methodology - The purpose of this study is to determine how shipping companies establish partnerships with third-party logistics providers and draws out the implications of the results. The survey methods used were personal interviews and questionnaires distributed to a sample population through e-mail, fax, mail, and telephone. A total of 600 questionnaires were distributed, of which 165 were returned. Among these, ten were excluded due to insufficient content; ultimately, 155 were used for the sample. The statistical data collection process was analyzed through data coating and a statistical package program. Results - This study argues that greater flexibility in policies, administration, and systems will be needed to significantly improve established business practices. In this dissertation, we primarily identify that in order to become a center of northeast Asian logistics, Korea must adopt a new paradigm and abandon the existing systems that are based on the economic and social systems that have stemmed from bureaucracy, inflexibility, chauvinism, and equalitarianism. Flexible policies, administration, and systems will be necessary to improve business practices. Domestic corporations must establish a strategic logistics hub and related network while simultaneously pursuing value-added logistics businesses by increasing their manpower and building a logistics information system. This will strengthen their competitive edge and lead to system improvements. Conclusions - Domestic corporations must adopt a new paradigm and use more reasonable business laws, systems, and policies that are based on market-driven flexibility and transparency. Moreover, social norms and regulations should be established to help ensure political and social security. Korea must also develop a culture of tolerance for foreign companies. Finally, the paradigm defining the policy governing the development of the capital city and its satellite cities in this context must be changed.

As interest in eco-friendly architecture and Korean traditional culture is increasing, interest in contemporary han-ok is steadily increasing. Recently, many people experienced the han-ok directly and indirectly with the attention of a commercial contemporary han-ok such as restaurants, coffee shops, and lodging facilities, and as a result, the house has a preference for the residence of the contemporary han-ok. Compared to modern residential houses, however, han-ok is lack the convenience of heating and cooling, energy management, security, and maintenance. For this reason, the increased interest and preference for han-ok does not lead to living in contemporary han-ok. This study was conducted in the following ways to improve inconvenience by applying smart home services to contemporary han-ok. Recent technology trends in smart home services and technologies developed and marketed to date have been identified in previous research cases and literature studies. Based on this, a list of smart home services and their application methods were derived that would relieve the inconvenience of contemporary han-ok for smart home services. We hope that this research will serve as a reference for subsequent researchers studying contemporary han-ok.

The rapid growth of network based IT systems has resulted in continuous research of security issues. Probe intrusion detection is an area of increasing concerns in the internet community. Recently, a number of probe intrusion detection schemes have been proposed based on various technologies. However, the techniques, which have been applied in many systems, are useful only for the existing patterns of probe intrusion. They can not detect new patterns of probe intrusion. Therefore, it is necessary to develop a new Probe Intrusion Detection technology that can find new patterns of probe intrusion. In this paper, we proposed a new network based probe intrusion detector(NePID) using anomaly traffic analysis and fuzzy cognitive maps that can detect intrusion by the denial of services attack detection method utilizing the packet analyses. The probe intrusion detection using fuzzy cognitive maps capture and analyze the packet information to detect syn flooding attack. Using the result of the analysis of decision module, which adopts the fuzzy cognitive maps, the decision module measures the degree of risk of denial of service attack and trains the response module to deal with attacks. For the performance evaluation, the "IDS Evaluation Data Set" created by MIT was used. From the simulation we obtained the max-average true positive rate of 97.094% and the max-average false negative rate of 2.936%. The true positive error rate of the NePID is similar to that of Bernhard's true positive error rate.
