The newly updated Rail Safety Act is required to build a comprehensive railway safety management system with corresponding accreditation regulations for the purpose of safe railway operations. However, such efforts would not be enough to achieve a successful safety-performance solely without being in place of an appropriate level of safety cultures in an organization. No research was taken place to propose a safety culture maturity model and its estimate procedures in Korean railway industries. The research reviews a variety of safety maturity models applied in many other industries and the process of conducting surveys in order to propose a framework of railway safety maturity estimates, with a set of railway safety elements. This research is expected to contribute in diagnosing weak areas and finding their appropriate treatment, along with in placing the railway safety certificate program from 2014.

In 1990s with the increasing of consumers' standard of life and change of life style, there has been an increase of import from overseas license brands and a new participation of big enterprises, as well as small and medium enterprises in local fashion market. As a leading fashion company with a long tradition and technique, the INDIAN brand of Sejung Inc. needs to establish a new image to preoccupy relative superiorty in the competition with other brands and satisfy future consumers in the present situation of 1990s. Therefore, for developing of its image, we made an investigation of three-dimentional marketing about business environment, and after setting up the B.I concept, we initiated to express a visual image. Through a made-up question after the completion of those works, we decided our logo mark and completed the entire design system, including the basic and applied elements of main design items of INDIAN B.I Finally, to maximize the effect of the brand identity, it is necessary for us to keep the principles in making the shape of design, to take care of them thoroughly, to make all the members' thinking and behavior unite concerned with the brand, and to execute continuous educational programs for practice of B.I. conciousness with the public relations when B.I. will be appeared on the market.

This paper compared historical energy use from 2000 between Japan and Korea and reviewed literature of mid-and long-term low carbon energy scenarios and plans in both countries released since 2000. In terms of energy use pattern, there are similarities between Korea and Japan; high dependence on energy imports, high proportion of manufacturing industry among OECD countries, closed electricity system disconnected with foreign countries, and high proportion of nuclear power generation with low proportion of renewable electricity despite of high potential of renewable energy. Differences are as follows; decreasing trend in Japan and increasing trend in Korea in terms of energy demand and supply, difficulty of exchanging electricity between regions in Japan unlike Korea, and prospect of nuclear power, that is, curtailing in Japan while expanding in Korea according to governmental plan. Energy Basic Plan in both countries established before nuclear accident in Fukushima required expanding about two times of nuclear energy by 2030, while civil society's energy scenarios suggested reducing energy demand, phasing-out nuclear power, and expanding renewable energy. This paper will serve as a base for future studies about long-term energy scenarios and plan in Japan and Korea.

Electronic Data Interchange(EDI) between a number of companies goes on increasing on the internet. Although a conventional EDI system reduces business process efforts, time, resources, etc., important information is easily and frequently exposed by well trained hackers and crackers, which inflict a severe loss on the company and even put the company under a crisis. This study integrates the conventional EDI system and Virtual Private Tet(VPN) to maximize an overall efficiency of speed and security in data transferring by the level of importance. The EDI system interfaced to IPSec and L2TP of VPN allows us to select two modes : the one focuses on a high speed with a low or a medium level security or the other does on a high level security with a low or a medium level speed. Both the company and the end users get a lot of tangible and intangible advantages by integrating the EDI system and VPN.

배관에 생기는 구멍이나 틈은 대형 사고의 원인이 될 수 있다. 이러한 배관의 결함을 찾기 위해서는 먼저 센서를 부착한 배관 탐사 장비를 배관에 통과시키고, 배관을 통과하는 중에 센서가 읽은 정보들을 배관 탐사 장비의 하드 디스크에 저장한다. 배관 통과가 완료된 후, 분석가는 분석 프로그램을 사용하여 탐사 장비에서 얻은 데이터에서 결함을 수동적으로 찾는다. 분석가가 데이터를 분석할 때 일반적으로 두 가지 패턴이 존재한다. 첫 번째 패턴은 일정한 구간의 센서 데이터를 순차적으로 분석하는 패턴이고, 두 번째 패턴은 현재 구간에서 이전 구간으로 되돌아가서 다시 분석하는 반복적인 패턴이다. 현재까지 만족할 만 한 수준으로 자동적으로 분석이 되지 않으므로, 분석가는 수작업으로 분석을 하는 경우가 많은데 이로 인해 최근에 읽은 부분을 전후 반복해서 액세스하는 반복적인 패턴이 많이 사용된다. 반복적 패턴의 경우 시스템의 성능을 향상시키기 위해, 이전에 읽은 배관 센서 데이터를 캐싱 할 필요가 있다. 그러나 기존의 분석 소프트웨어에는 캐싱 기능이 없으므로 반복적 패턴일 경우 데이터베이스에서 동일한 데이터를 반복적으로 읽는 문제를 가지고 있다. 본 논문에서는 배관 센서 데이터를 효율적으로 관리하는 캐쉬 관리자를 설계하고 구현하였다. 세부적으로는, 배관 센서 데이터를 시계열 데이터로 간주하고, 시계열 데이터에 대한 캐시 관리자를 제안하였다. 본 논문은 배관 탐사 장비에서 획득한 데이터들을 시계열 데이터로 간주하여 데이터베이스 측면에서 이러한 문제들을 접근하였다는 점에서 의미가 있으며, 향후 이 분야에 대한 많은 연구들이 나올 것으로 기대한다.

This study was conducted to compare the mortality number of swine between before and after HACCP implementation on swine farm. Also, we analyzed the reason for implementing HACCP system, advantage and disadvantage of HACCP system implemented swine farm. The study was carried out by randomly selected fifty swine farms located in all around Korea. The results were as follows: The mortality number of swine before HACCP system was found to be 288.30, 122.90, 91.08, 18.22, and 108.10 in respiratory, diarrhea, abortion (stillbirth), an accidental death and others, respectively. However, after HACCP implementation, it decreased, without significantly, to 261.60, 101.10, 85.91, 16.37, and 108.60, respectively. Therefore, Therefore, the total number of mortality pig decreased from 628.70 (before HACCP) to 573.60 (after HACCP). The enhancement of farm competitiveness (26.92%) and hygienic and safety pig production (23.43%) were ranked as the first and second proposes for implementing HACCP system on swine farm. The major advantage of implementing HACCP were improvement the farm sanitation management level (20.90%) and the major disadvantage was surveyed as HACCP records (23.10%). We are expecting that our results might be used for producing safer livestock products by improving livestock products HACCP policy.

In this paper, we propose an on-line mechanism that simultaneously detects cracks and profiling pavement blocks to detect the displacement of ground surface adjacent to the excavation in the urban area. The proposed method utilizes a 2D laser to profile the information about pavement blocks including the depth and distance among them. In particular, it is designed to enable the detection of cracks and portholes at runtime. For the experiment, real data was collected through Gocator, and trainng was carried out using Faster R-CNN. The performance evaluation shows that our detection precision and recall are more than 90% and the pavement blocks are profiled at the same time. Our proposed mechanism can be used for monitoring management to quantitatively detect the level of excavation risk before a large-scale ground collapse occurs.
