경기육괴 서부는 현생이언의 섭입/충돌 지구조운동을 기록하고 있어 한반도의 지각진화사를 이해하는데 매우 중요한 지역이다. 본 논문은 경기육괴 남서부 곰섬 일대에 분포하는 태안층에 대한 구조지질학적 연구 결과를 제시한다. 야외조사를 통해 획득한 구조요소들의 상관관계를 해석하고 구조구 별 하반구 투영 해석, 하향 투영 단면 작성을 수행한 결과, 연구지역 내에는 적어도 세 번의 서로 다른 변형작용($D_1$, $D_2$, $D_3$)이 인지된다. (1) 첫 번째 변형작용($D_1$)은 백운모와 흑운모의 정향배열로 뚜렷하게 정의되는 층리와 아평행한 광역엽리를 형성하였다. (2) 두 번째 변형작용($D_2$)과 관련하여 주로 북북동-남남서 방향을 가지는 저각의 수축성 단층과 이와 관련된 파랑습곡 및 벽개가 형성되었다. 파랑습곡의 힌지(파랑선구조)는 대체로 남남서~남남동 혹은 북북서~북북동 방향을 향해 저각으로 침강한다. 파랑벽개는 주로 서쪽으로 저각 경사하나 일부 구조구에서는 동쪽으로 경사하는 양상이 인지된다. (3) 세 번째 변형작용($D_3$)에서는 전반적으로 남동 방향으로 침강하는 힌지를 가지는 대규모 습곡들과 이와 관련된 북동-남서 방향의 단층들이 형성되었다. $D_3$ 변형에 의해 형성된 대규모 단층과 습곡의 경우 '단층 수반 습곡(fault-related fold)' 혹은 '습곡 수용 단층(fold-accommodation fault)'으로서 해석되며, 이는 기원적으로 상호 간 밀접한 관계를 가짐을 의미한다. 연구결과는 태안층 및 더 나아가 섭입/충돌 조산대로서 경기육괴 서부가 기록하고 있는 구조적인 진화사를 규명하는 데에 도움이 될 것으로 기대된다.

When the load in a multi-cell orthogonal frequency division multiple access (OFDMA) system is allowed to excessively increase in face of frequent handover, the cell area becomes smaller than the designed size, and thus continuity of quality of service (QoS) for handover requests cannot be guaranteed. To efficiently support the mobility of a mobile terminal (MT), we should adaptively cope with the resource demand of handover calls. This paper proposes a twofold resource-reservation scheme for OFDMA systems to guarantee continuity of QoS for various mobile multimedia services during MT handover from lightly to heavily loaded cells. Our twofold scheme attempts to guarantee service continuity for handover and to maximize resource allocation efficiency. We performed a simulation to evaluate our scheme in terms of outage probability, handover failure rate, total throughput, and blocking rate.

This study analyzed tourists' intention at Gangcheon Mountain, Sunchang-gun for local tourism. The contents of study included impression, characteristics, specialized resources, development direction, intention of visit and its form, destination prior and post visit, travelling expenses, and development form of tourism. The results were as following. Impression and characteristics showed that gochujang and fermentation industry established a strategic ground of local development. Intention of revisit of tourists was relatively high by 97.1%. Furthermore, tourists were mainly family units and they preferred family-based recreational type for the future local tourism development form. Therefore, a development strategy will be required that involves inexpensive accommodation, unique local food items, agricultural-specialty products and local tour packages. For invigoration of local tourism, recruitment of skilled managers for farm village experience will be necessary as well.

Crashworthy design of trains is now indispensable procedure in modern railway vehicle design for ensuring the safety of Passengers and crew. It is now widely recognized that a more strategic approach is needed in order to absorb higher level energy in a controlled manner and minimize passenger injuries effectively. The first design step in this strategic approach is the design of the front end structure(so called HE extremities) to absorb a large part of total impact energy and then the structure of passengers non-accommodation zones(so called LE extremities) is designed to absorb the rest of impact energy. In this paper, the passengers entrance door area is selected as the LE(low energy) extremities and the design of the LEE was carried out. The main part of LEE design procedures is the design of energy absorbing tubes. For this purpose, the several tube candidates are introduced and compared to each others with numerical crash simulation.

The purpose of the paper is to examine the nature of population distribution during the past 25 years; to evaluate effect of population redistribution policies which have been adopted by the government; and to suggest desirable future policy directions. The distinctive features of population distribution during the period of 196O~85 can be summarized as progress of rapid urbanization, decrease of absolute number of rural population and heavy concentration of population in the Seoul metropolitan area which have resulted in population maldistribution among regions. The problem of population concentration in the selected one or two large urban centers was first recognized by the government as early as in 1964. Since then numerous policy measures have been adopted to reduce the population concentration into the Seoul metropolitan area and thus to guide a sound population redistribution among regions. The overall assessment of various policies on population redistribution, however, revealed that the effect of the policy efforts has not been great as they originally anticipated. Various reasons can be cited for the failure of the past policies. Among them the followings were frequently mentioned; lack of integration among policy measures; weak linkage between relocation and accommodation; and non-existence of single authority for overall implementation of the polices. Based on the past experiences the followings are suggested in pursuing future policies. First, the short-term objective or target should be clearly defined. Second, policy measures have to be designed to go with rather than against market forces. Third, indirect incentives or aids are more effective than direct controls or regulations. Fourth, local participation has to be secured in every phase of policy formulation and implementation.
