Nowadays, the occurrence of Malware is steadily increasing. The Malware is also becoming more intelligent, advanced and changing into various types. With the development of the information industry, the economic and monetary value of the information is going up and the damage due to the leaked information by the Malware is also increasing. This paper investigates the general usage of the User Agent in the HTTP Header, studies the Malware production techniques by transformation of the User-Agent information and suggests the technical and political counterplan against them.

Construction accident happens all of the process in work and contains materials types of causes. Especially, temporary work material in the great problem in industrial accident. Because temporary work In essential to build the main structure. The most frequent type of accident by the temporary work is the falling and so on. Its causes were the failure of scaffolding, imperfection of temporary material etc. These accident properties the Primitive and repetitive accident. The prevention counterplan of construction accident by temporary material work in need to protect worker and make more safer construction site. Therefore in this paper analyzed of the serious accident of construction by the temporary work material and present reasonable solution method to reduce the construction accident by the temporary work material.

Using road traffic noise, noise map for CheongJu city was drawn. Noise level is estimated and many regions of the city are classified noise excess area compared with environment standard value. Counterplan for the noise excess areas is presented in this study. Noise reduction methods are given in many ways, for example soundproofing walls, low noise pavement, low noise arrangement of buildings and low noise windows.

This is a case study on the counterplan for reducing agricultural environmental pollution in the SANHYUN Livestock Club through participatory research from March, 1993 to June, 1995. In the monthly meetings, the active discussion about agricultural environmental pollution gradually increased with the village people, Club members and other people because of a consciousness-raising created through discussion activities. In addition, the Club members have established a septic tank and accumulation store-house after active participation in such discussions about the environmental pollution. After two years, the number of septic tanks and accumulation store-houses has increased from two to 10. Gradually all village people are becoming more aware of village environmental pollution. Four non-member farmers have constructed a septic tanks and several member farmers have constructed the fermentation system of sawdust and hulls.

The purpose of this study is to develop a dynamic DSS (Decision Support System) interfaced with GIS (Geographic Information System) and agriculture information network, In this study, DSS was developed to assist services which required tremendous and real time data in national scale. The data transmitte'd from the local area by the agriculture network were stored in DBMS (Data Base Management System) and analyzed by GIS. GIS and database tools used in this study were ARC/INFO 7.1.1 and INFORMIX 4.0. ACSAS (Agriculture Calamity Service Asist System) by the system prototype was constructed to solve the problem about the drought counterplan service which was to take the responsibility in the Ministry of Agriculture. It was easy to transfer, process, and analyze the information using the system. Specially, the meteological, the reservoir storage rate and the drought counterplan information were spatially analyzed by the functions of GIS.

In recent year, as the demand about low vibration and noise vehicle is increased constantly. automobile companies try to a lot of things to achieve this demand. Gear rattle vibration become an emergency problem to be cured at idling. There are two kinds method to reduce idle gear rattle vibration One is optimization of clutch damper design parameters(stiffness, hysteresis torque, preload, length of lst stage) the other is system parameters modification(inertia, drag torque, backlash, etc) But these methods are impossible to estimate influence rate of each gearpair on the idle gear rattle vibration. In this study, 14degrees of freedom nonlinear model is developed to analyze influnce rate of each gearpair on the idle gear rattle vibration and the counterplan to reduce the gear noise is suggeted through the shift system modification.

Traffic has a very important function but has caused such social problems as traffic congestion parking and traffic accidents in metropolitan areas. It is difficult to examine the causes of traffic accidents related to human life, which occur by human, vehicle and environmental factors. But human factor is the only measure requlating these factors together an analyzing factors influencing establishment of counterplan of traffic accidents. Consequently , this study employs the principal component analysis and stepwise multiple regression analysis to estimate the characteristics and influential factors of traffic accidents and defines the typical patterns of happening lots of traffic accidents. Accordingly, this study establishes an acknowledgement model of the causes and preference model of the counterplan of traffic accidents using Multi-Dimension Preference(MDPREF) method.

According to the statistics of KMST (2010~2019), 68.5% of marine casualties have been occurred in fishing boats in the last 10 years. Although the incidence rate of annual average per ship is 10.4% for merchant ships and 2.3% for fishing boats, it is necessary to first reduce the marine casualties of fishing boats in order to reduce the occurrence of the whole marine casualty, considering that the number of registered fishing boats are 86.5% of the total. In this study, the top 10 fishing types with high occurring marine casualties in the past 10 years were selected using the statistics of KMST. Then, the causes of the marine casualties, focusing on the collision, were analyzed and counterplan were suggested. The biggest marine casualty that the top 10 fishing types have caused in the past 10 years was a collision, accounting for 71.7% of the total, and the rest were less than 10.0% each. Also, it was found that the biggest environment and cause of the collision were due to human factors such as poor look out or negligence of duty. Eventually, it was concluded that a reduction in the human factors for the causes basically, could lower the incidence of the marine casualties. Therefore, if the continuous and systematic correcting education of the attitude toward the ship operating of seafarers could conducted with the focus on the main human factors, the whole marine casualties will be expected to decrease gradually.
