  • It is more important to realize safety management, medium-large accident prevention and risk prediction as accident of industry facilities can generate enormous physical and human damage because most energy plant might handle toxic substance. Especially, atmospheric dispersion system, which is able to simulate situation, have been used for release accident of toxic substance since the accident can show different of dispersion range and velocity according to release material, storage facility and atmospheric status. However those systems have been used generally in design step of industry facility and are difficult to deal with release accident quickly. Although some researches and cases have been studied for using real-time atmospheric information, there are insufficient system for processing quickly release accident. This paper aims to develop real-time smart atmospheric dispersion system that can deal with release accident quickly by enhancing distinct characteristics and efficiency of energy plant, and select release time and area using intelligent algorithm as accident prevention type.

  • This paper proposes an SWAD-KNH(Sybil & Wormhole Attack Detection using Key, Neighbor list and Hop count) technique which consists of an SWAD(Sybil & Wormhole Attack Detection) module detecting an Worm attack and a KGDC(Key Generation and Distribution based on Cluster) module generating and an sense node key and a Group key by the cluster and distributing them. The KGDC module generates a group key and an sense node key by using an ECDH algorithm, a hash function, and a key-chain technique and distributes them safely. An SWAD module strengthens the detection of an Sybil attack by accomplishing 2-step key acknowledgement procedure and detects a Wormhole attack by using the number of the common neighbor nodes and hop counts of an source and destination node. As the result of the SWAD-KNH technique shows an Sybil attack detection rate is 91.2% and its average FPR 3.82%, a Wormhole attack detection rate is 90%, and its average FPR 4.64%, Sybil and wormhole attack detection rate and its reliability are improved.

  • The Seoul subway system has one of the highest transport shares in the city of Seoul. A high number of passengers means that a high level of crimes of all kinds occur on the city's subway system. As such, Seoul Metro, created the Subway Protective Guards System in 2009, in an effort to enhance safety on the subway. But this innovative new system did not resolve problems. In fact, many citizens came to question the effectiveness of the new system, as it did not yield tangible results. This study seeks to deduce the problems and activation strategy of the Subway Protective Guards System. An in-depth study was conducted by interviewing subway protective guards who were squad leaders with five or more years of relevant work experience. Semi-structured interview analysis was utilized to evaluate their responses. Specifically, their responses were deduced to identify the strengths and weaknesses internal to the system and the opportunities and threats posed by the environment external to the system. This study presents measures to improve the system based on the aforementioned analysis. Measures for improvement focused on the following areas: the adoption of an education system in response to terror; recruitment and the possibility of becoming a permanent employee; obtaining partial judicial powers; improvement of work environment; and intensifying the promotion of the system.

  • Fire investigation to examine ignition and combustion enlargement etc., to assess fire damage and to investigate a fire suspect, is used as a valuable data for better fire suppression and fire prevention police. Fire investigation is divided in to fire-cause investigation, fire-damage investigation, and fire-criminal investigation. At present, fire-cause investigation is lacking In scientific technology; specially is deficient in accurate damage assessment. And considering fore criminal investigation, since the police lacking in specialty on fire take exclusive charge of fire criminal investigation upon general investigation, it is difficult to investigate fire criminal effectively. Finally deficiency in fire investigation operates as very big blind-spot in fire safety having important axis in social safely; the loss is shifted on nation's shoulder. To solve those problems, legal, institutional, operational preparation is urgent. And so, this study tried to stabilize specialty of fire-fighting to offer more active, qualitative fire administration service, and to contribute to public peace and welfare by grasping problems after diagnosing Korean fire investigation and proposing the solutions.

  • For changes in the distribution structure these days, consumer demand is moving rapidly from offline to online. The consumers' mentality to purchase products conveniently is reflected in this phenomenon. Also for agricultural products, safety to protect contents, brand and design which can provide credibility to consumers are recognized as most important than ever. Especially, strawberry is thin-skinned so that the quality of product may deteriorate even with weak impact and shaking, so it is significantly influenced by the structural packaging or material. Also, strawberry is frequently distributed through direct trading, it is the reality that the package design of strawberry is less competitive than that of other products due to inadequate environments of commercial farms. That is, the demand of strawberry increases everyday but the strawberry package cannot fulfill the needs of producers and consumers. In order to reinforce competitiveness in strawberry sales, it is urgent to carry out fundamental studies regarding the development of package. Therefore, the purpose of this study is to supplement and improve issues arising from the usage of current strawberry package. Through the analysis of strawberry package elements (shape, material, design) and understand the points of improvement sought by producers and consumers through IPA MAP (importance, satisfaction level) analysis.

  • Our country automatic wet pipe sprinkler system of hydraulically designed system has not deviated from the pipe regulation process, therefore we face limitations when using an independent method to hydraulically designed system. Therefore. after reviewing a developed country's methods using the drainage-density concept, we found it necessary for our country to introduce the drainage-density concept. Currently, under the National Fire Safety Codes(NFSC), this does not solve the problem and the limitation of hydraulically designed system because different problems arise depending on where the head was installed. To make improvements, first, such as the developed country, overcome the difference by introducing the drainage-density concept to determine the amount of drainage. Second, by using diverse head caliber and decreasing the limits on the amounts of distribution, we can expect a leveling off of the drainage density. Third, using the increase of hydraulically designed system through the application of the rule to hydraulically designed system, finally, development to performance based fire protection design.

  • According to Electronic Times(2012. 1. 3), "PMO was introduced from 1950s in the USA and as of 2010, PMO participated in 84% of project ordered by public and private sector." And Ministry of public administration and security announced that the Ministry will organize Task Force for arranging "standard for introduction and operation of PMO" for support of project implementation and strengthening specialty of ordering organization, and then, actively launch the Task Force from February, 2012. Thus, necessity of PMO is regarded as natural in some aspect but thesis for doctoral degree written by Kim Gi-yeong(2007) suggested, "performance of several projects begun at the same time cannot be interpreted as high according to whether PMO team exists or not." Martin et al.(2005) asserted, "according to whether PMO team exists or not, but there is no significant difference in other factor." In the contradictory situation, it is necessary to perform more various approaches for performance and necessity of PMO in the academic aspect.
