우리나라 산업과 경제의 근간에는 중소기업이 뿌리의 역할을 하고 있으며 대부분의 기술적 혁신은 대기업보다 중소기업에서 일어나고 있다. 기술개발과 기술혁신만이 중소기업이 치열한 경쟁구도 가운데 생존할 수 있는 유일한 길이기에 매진하는 한편 기술보호에는 관심과 투자가 인색한 편이다. 그로 인해 산업기술유출 사고가 빈번히 일어나고 있으며 이에 대한 개선대책을 중소기업 여건상 충족시키기 어렵다. 유출사고가 발생하였을 때 범죄 행위를 입증하기 위해서는 가장 핵심인 디지털증거가 필요하지만 관리상 허점으로 인해 디지털증거가 훼손되고 삭제되거나 하는 등의 문제가 발생하곤 한다. 따라서 본 연구를 통해 기술유출사고 유형에 따른 디지털증거기반의 대응방안을 설계하고자 한다. 실제로 발생하였던 기술유출사고 유형을 분류하고 내부정보유출방지솔루션을 운영하는 중소기업 보안환경에서 디지털증거 확보 방안을 연구하려 한다.

Since modern times, lack of housing had become more serious in the cities when going through urbanization process. As a countermeasure against the situation, multi-family houses raised its head at the end of 1980s. Regarding multi-family houses, which is mainly targeting low-income group, however, only quantitative supply has been focused with no enough research about space planning. For now that the supply of housing in the cities reached certain level, there is a need of planning multi-family house considering the demands of residents. Therefore, the purpose of this research is to identify and analyze the demands of owners and tenants of multi-family house in an improvement district of housing environment for housing improvement, and to extract house planning components. As a research methodology, small-group workshop panel using drawings and mock-up has been practiced to reach residents' concertized opinion. After dividing the residents group into 2 groups which include owners group(3 participants) and tenants group(3 participants), 3 times of workshops covering 2 days are conducted for each group. Actual-condition investigation of the participants' houses was ran side by side with workshop. As a result, difference in their point of view about the reasons and the direction of housing improvement was identified, on the other hand that there is similarity in their demands such as guaranteeing independency and privacy among households.

It is significant to redevelop the deterioration reservoir through raising for countermeasure to climate change and Earthquake improvement of reservoir. This study aims to investigate the behavior of deterioration reservoir with poor-fabricated core subjected to raising water level and earthquake using numerical analysis. From the analysis results, water level raising and earthquakes induce crack and subsidences at the crown and the front side of deterioration reservoir. For the reinforcement of the deterioration reservoir is required appropriate measures method and raised method suitable, drainage and slope protection method judged to be necessary.

If industrial safety statistics are analyzed, among the total of 2,114 dead people from industrial disasters in 2011, construction workers took 29.4% with 621. The construction industry makes a lot of efforts to reduce the death toll. However, since the measures are not from the analysis of root causes but from superficial countermeasure plans near general matters, it is in a situation that the actual effectiveness is marginal. Therefore, in this paper, improvement measures were intended to be prepared in order to reduce accidents, by inspecting safety control systems of target companies with high accident rates among major construction firms and extracting overall problems of them.

There are many risks in constructing tunnel-structure. To prevent these risks from occurring and secure safety, the precise and rapid survey of inside displacement of the tunnel is required. But nowadays the measurement of the crown settlement, convergency, and surface settlement depends on general kinds of method which use total station or level. In the way to provide data about maintaining structure according to recent improvement and progress of measuring technology, 3D laser scanning is used. It solves the problem of reliability in measuring displacement of existing structure, provides material that enables to estimate shape change of structure visually, and makes it possible to deliberate speedy countermeasure. By this three dimensioning it is possible to make efficient use of structure maintenance and field measurement

In the previous study, a module-type vibration analysis system using modular approach is developed for the purpose of analyzing the torsional vibration of vehicle driveline. In the present paper, the system is utilized to investigate the torsional vibration of the driveline of a middle duty truck. The driveline with driving condition is modeled and the torsional vibration response is simulated. The resonance 45Hz is found at engine speed 900rpm and the resultant vibration is very high. It shows favorable agreements with reference data. The effects of parameter change on torsional vibration are also investigated, so it is clarified that clutch characteristics, axle shaft stiffness are very influential on reduction of vibratio. So the countermeasure is proposed for the clutch characteristics. The reduction of torsonal vibration by 8rad/sec is obtained.

Vibration table is required to obtain high packing density in expendable pattern casting process. Packing density. which is an important manufacture factor, depends on the vibration pattern induced by vibration table. In general, circular vibration pattern is recognized as the best pattern. The existing vibration table is investigated to identify current vibration pattern and consider a countermeasure. Modal test is utilized to identify the dynamic characteristics of vibration table, and finite element method is used to propose the improved design. In simulation using finite element method, the position of stiffeners is obtained to satisfy the required dynamic characteristics.

Agricultural water occupies the largest portion of total water use in Korea, and generally researches on the development of agricultural water have been stressed on the demand of agricultural water itself. But it is unavoidable to change a policy from the development of water resources to cope with the increase of water demand to the effective management of existing water resources. Evaluation of the decrepitude of irrigation facilities and their reasonable maintenance are important for the effective supply and use of agricultural water. Therefore it is necessary to develop evaluation technique that diagnoses the current condition of irrigation canals and suggest a countermeasure to improve the found problems. 25 items in 6 classes were selected for the evaluation of irrigation canal systems, and the weighted value between the items was calculated using AHP (Analysis Hierarchy Process) method. The current condition of the irrigation facilities was evaluated from the class evaluation marks, and ranking was decided from the total marks between the projects, and finally the priority of the project for the improvement was given.

Predict-Plan-Do is the main point to settle Safety management well, but we have neither Predict nor Plan. So just like the system of English CDM is necessary to be adapted in construction work which makes them work in full responsibility by clarifying the responsibility located step by step from planning to designing & constructing-To adapt this system needs more money for Safety than now, but this system makes companies earn maximum confidence & profit by accident prevention. Furthermore leads the nation and the society to earn large profit, then open the road to Welfare State. If you sees only the things such as money, profit, etc before your eyes, no more safety remains. That means no more respect of persons and no more welfare state.

It is important to build new irrigation facilities as a countermeasure against new water demand, however the effective use of existing facilities is rather advantageous economi cally and socially.Since many irrigation facilities were constructed before 1960's, the functions of them have been declined and rehabilitation of deteriorated facilities needs great expenses. To operate the irrigation facilities efficiently, the criteria for the maintenance and repair of irrigation facilities should be established according to the importance of structures. for the reasonable evaluation of the irrigation facilities, the Irrigation Facility Inquiry System(IFIS) was developed. The present status of the irrigation facilities are grouped by the type and scale of structures, and the characteristics of irrigation facilities under control of Farmland Improvement Association(FIA) were analysed.
