This research is concerned with how seepage through the permeable foundation stratum results upon the safety of embankment constructed on riverbed-the Kumdan industrial complex. The data from the in-situ tests, laboratory tests, and computer program are presented and discussed on the effects of seepage of an alluvial formation. Uplift pressure values were re-presented in the form of pore pressure with the aid of computer program. Emphasis was placed on assessing the influence of seepage under the riverbed embankment. In particular it is shown that: (1) some of levees are constructed on foundation composed of various kinds of alluvial materials underlaid by some form of various kinds of alluvial materials underlaid by some form of bedrock and forms sandwich typed permeable foundation formation that have potential fissuration in case that depth of low permeable upper soil stratum is shallow. (2) this kind of levees as that of the Kumdan industrial complex need to have seepage control methods that are following proposals of reducing quantity, withstanding uplift pressure and lowering piezometric head; ① sheetpile cut-off wall ② compacted barrier of impervious soil ③ grouted or injected cut-off ④ impervious wall of mixed in-place piles.

Characteristics of frost heaving were observed for the soil filled with in the natural soil bath. From this study, the following conclusions were drawn. 1. The frozen thickness for soil was thought to be a constant. 2. The amount of ground frost heave increased in line with an increase of the temperature gradient. 3. In cold region, the effect of the tapered pile was low. 4. The amount of ground frost heave coincided with the amount of wate migration at the freezing front. 5. In the case of ice lens near the ground surface, the effect of a sublimation was small. 6. The pressure action on structure was a great difference with the shape of underground object.

In this paper, new solution analyzing soil stiffness of the pile subjected to dynamic loading is developed by using henkel function. Thus. this solution is comparison with Novak solution. To investigate the effects of soil properties of the disturbed zone around a pile subjected to the torsional harmonic vibration, the parametric study is performed. The determination of the soil stiffness of the soil around a pile is performed by dividing the soil profile into disturbed zone and original zone. The conclusions obtained from this study are as follows: 1) Soil stiffness is greatly affected by the values of soil properties. 2) Real parts of soil stiffness is nearly not affacted by the magnitude of disturbed zone. 3) The real and imaginary parts of the soil stiffness increase as the shear modulus ratio and the poisson's ratio increase.

The "4th Development of Seaport on the Pusan" project involved the strengthening of soft soil in a 739,600㎡ site at the Gam-man dong of Pusan. For the design of improvement, conventional bore hole, laboratory tests and piezocones were carried out. This construction site lies over 0.0 to 22.0 m of alluvial and residual soft clay under the reclamated sand fill stratum. The coefficients of consolation obtained in the field measurement and piezocones were greater than the ones obtained in the laboratory tests. The reason for this result seems to be mixing of sand and clay at the top of clay-stratum caused by the reclamation of sand-fill.

오늘날 우리사회는 개인이나 사회, 국가를 막론하고 다양한 형태의 크고, 작은 갈등 과 분쟁 그리고 테러리즘과 재해의 끊임없는 발생으로 국가적인 위기는 여러 가지 측면에서 나타나고 있다. 국가위기관리의 대상으로는 생각되지 않았던 대규모의 재해관리 문제를 이제는 국가위기에 반드시 포함시켜야 할 정도로 국가적으로 중요한 문제로 대두되고 있으며, 요인테러리즘 또한 군사적 문제를 다루는 전통적 안보 및 재해와 더불어 국가위기관리의 대응 측면에서 매우 중대한 문제가 아닐 수 없다. 특히, 국가원수나 정부수반 등 각국 지도자를 공격 대상으로 한 요인테러는 지속적인 증가 추세를 보 이고 있으며 또한 치명적인 테러 행위 발생시 국가적인 위기를 초래하는 등 후유증이 크게 발생하고 있다. 따라서 요인테러의 위기관리를 위한 발전방향으로 첫째, 위기관리를 위한 대응체제를 구축하기 위해 "경호관계법"과 "테러방지법" 등 관련 법률의 조속한 제정ㆍ보완이 이루어져야 하며, 둘째, 경호의 기본원칙에 의한 경호안전활동의 강화조치로 경호위해 요소를 사전제거 해야 한다, 셋째, 현장 구성원에 대한 교육훈련의 강화로 현장에서 발생하는 제반사항에 대해 극복능력을 증대시켜야 하며, 넷째, 요인테러가 직접 위해 목적 뿐만 아니라 간접 위해 목적을 달성하기 위한 테러가 증가함에 따라 위기관리를 위한 다양한 경호기법을 개발하는 등 국가요인에 대한 암살 및 테러의 가능성을 최소화 하겠다는 의지로 예방경호활동에 중점을 두고, 각종 테러위해요소를 사전에 제거하는 등 위기관리에 만전을 기해야 한다.

Characteristics of frost heaving were observed for the soil, filled with in the bath which had same soil, initial moisture condition and different cooling temperature. From this study, the following six conclusions were drawn. 1. The frozen depth and the frost heaving pressure increased, but the amount of the frost heave decreased with the low of cooling temperature. 2. The freezing rate varied irregularly depending on voids resulted from development of ice lens and water intake, but it generally decreased with the elapsed time. 3. The amount of frost heave increased with following of a growth of ice ice lens and was almost equal to the total thickness of ice lens. 4. The frost heaving pressure was influenced more strongly by the temperature rather than the pattern of frozen soil. 5. The influence of the external temperature became small with the increase of the frozen depth, temperature variation tended to slow. 6. The thermal movement resulted from the external temperature was mostly shifted towards freezing direction, thermal movement towards horizontal direction compared with freezing direction was very small. The data obtained from this study was based on the phenomenon of frost heave by maintaining a constant temperature. The effect of temperature on frost heave was explained sufficiently by the data, because there was no irregular environmental change as natural phenomenon.

Terrorism which became today's common phenomena over the world is one of the most serious threats the world confront. Although International society make and operate outstanding anti-terrorism system, terror would never end without solving fundamental problems. The main body of terrorism converts from nation to organization and from organization to cell, which makes it difficult for us to recognize the main body. Since the target of today's new terrorism is many and unspecified persons, terrorists will never hesitate to use mass destruction weapons such as nuclear, biological, chemical weapons, and also use cyber-technique or cyber-terrorism. So, effective counter-terrorism measures should be performed as follows. First, it must be better for international society should make long-time plan of solving fundamental problems of terrorism other than to operate directly on terror organization and its means. Second, preventive method should be made. The most effective method of eradicating terrorism is prevention. For this, it is necessary to remove environmental elements of terrorism and terrorist bases, and to stop inflow of money and mass destruction weapons to terrorists. Third, integrated anti-terror organization should be organized and operated for continuous counter-terrorism operations. Also international alliance for anti-terrorism should be maintained to share informations and measures. Fourth, concerned department in the government should prepare counter-terrorism plans in their own parts as follows and make efforts to integrate the plans. - Ministry of Government Administration and Home Affairs : conventional terror - Ministry of Health and Welfare : bio-terror - Ministry of Science and Technology : nuclear-terror Especially, they should convert their policy and operation from post-terror actions to pre-terror actions, designate terror as national disaster and organize integrated emergency response organization including civil, government, and military elements. In conclusion, pre-terror activities and remedy of fundamental causes is the best way to prevent terror. Also, strengthening of intelligence activities, international cooperations, and preventive and comprehensive counter-measures must not ignored.

Using a newly deviced permeametcr the effect of hydraulic gradient on permeability in sands was investigated, and following observation was made: 1. The flow behavior of water through uniform and graded sand is not linear between velocity and hydraulic gradient except dente sand. 2. T he relationship between permeability k and void ratio e is found to be approximately linear for uniform and graded sand. It is felt that Daroy's Law is not valid for through sand when k is not a constant but is a function of the hydraulic gradient.
