최근 54년($1951{\sim}2004$년) 동안 한반도 상륙태풍에 대한 기후학적 특성 분석이 이루어졌다. 한반도 상륙 및 영향 태풍의 빈도는 1980년대 후반 이후 급격하게 증가하였다. 한반도에 상륙하는 태풍의 진로 또한 변화하였다. 과거에는 한반도 서해안의 중 북부지역에 상륙하여 동해를 지났으나, 최근 들어 남해안에 상륙하여 동해로 지나가는 진로가 두드러졌다. 이는 전향점이 최근 들어 남동쪽으로 이동하였기 때문이다. 결국 한반도 상륙 태풍의 진로 및 전향점이 남동쪽으로 이동한 것은 북태평양 고기압이 동쪽으로 이동하는 추세와 관련이 있었다.

본 연구에서는 1951~2008년까지 58년 동안 북한에 상륙한 태풍의 빈도, 강도, 진로 및 피해 특성에 대해 분석하였다. 분석 기간 동안 태풍 빈도는 감소하고 강도는 약해지는 추세였다. 이러한 강도 변화는 대부분의 태풍이 온대저기압 상태로 약화된 후에 북한에 상륙하여 영향을 주었기 때문이다. 태풍 진로는 중국과 남한을 경유하거나 서해안에 직접 상륙하는 3가지 유형으로 분류되었다. 북태평양고기압과 태풍 진로와의 관련성 분석에서 북태평양고기압은 태풍이 중국을 경유하여 상륙할 경우 서쪽으로 확장하였고, 서해안에서 직접 상륙할 경우와 남한을 경유하여 상륙할 경우에는 북쪽으로 확장 발달하였다. 또한, 태풍 재해가 발생한 총 5건의 사례 중에서 2000년 프라피룬은 서해안에 직접 상륙하였으며 바람에 의하여 약 60억 달러의 경제적 피해가 발생하였고, 2002년 루사는 남한을 경유한 후 상륙하였으며 강수에 의해 약 50만 달러의 경제적인 피해가 발생하였다.

This study was conducted to investigate the relationship between the climbing up event of Luciola lateralis larvae and water temperature. In the laboratory condition, the larvae did not come out of water at constant temperature condition of 19.3${\pm}$$0.3^{\circ}C$ and tried to climb up at varying temperature condition of 20${\sim}$$22^{\circ}C$ (mean temperature 20.9${\pm}$$0.9^{\circ}C$) without success. However, they climbed up at constant temperature condition of 20.8${\pm}$$0.6^{\circ}C$. The frequency of the larval climbing up was highest as 63.6% at 20${\sim}$$21^{\circ}C$. The most larvae climbed up at approximately $21^{\circ}C$ of average daily water temperature, In the natural condition, the larvae climbed up at 19.8${\sim}$$21.7^{\circ}C$ and the frequency of the larval climbing up was high as 80.4% at 20${\sim}$$21^{\circ}C$. The larval climbing up was also little observed at 19${\sim}$$20^{\circ}C$ at which no larval climbing up was found in the laboratory experiment. No larvae attempted to climb up when water temperature was below $19^{\circ}C$ and above $22^{\circ}C$. It took 18 days from climbing up of larvae to appearance of adults. In its habitat, the range of water temperature required for larvae to climb up is assumed to be 19.6${\sim}$$21.8^{\circ}C$ and the most suitable water temperature may be 20.4${\pm}$$2.3^{\circ}C$. Therefore, the range of water temperature required for larvae to climb up is assumed to be 19.8${\sim}$$21.7^{\circ}C$, and the suitable water temperature range for larvae may be 20${\sim}$$21^{\circ}C$, and the most suitable temperature is thought to be $21^{\circ}C$.

This paper deals with complexity theory to describe amphibious warfare situation using EINSTein (Enhanced ISAAC Neural Simulation Tool) simulation model. EINSTein model is an agent-based artificial "laboratory" for exploring self-organized emergent behavior in land combat. Many studies have shown that existing Lanchester equations used in most war simulation models does not describe changes of combat. Future warfare will be information warfare with various weapon system and complex combat units. We have compared and tested combat results with Lanchester models and EINSTein model. Furthermore, the EINSTein model has been applied and analyzed to amphibious warfare model such as amphibious assault and amphibious sudden attack. The results show that the EINSTein model has a possibility to apply and analyze amphibious warfare more properly than Lanchester models.

Based on the typhoon paths landed on the southern coast of Korea, the distribution of typhoon moving directions follow the Beta probability density function and that of pressure drops in typhoon eyes follow the Rayleigh probability density function. Consequently, the extreme typhoon simulation scenarios for six landing positions are determined as most probable one in moving direction and extreme one of Typhoon Maemi level in pressure drop. The variation of storm surges in Masan bay associated with simulated typhoon landing position is analyzed through the numerical experiments in the next paper as the second part.

21세기는 생명공학 전쟁시대라고 일컫는다. 실제로 생명복제 특허전쟁은 우리나라에도 이미 상륙했다. 복제양 돌리를 탄생시킨 로슬린연구소가 복제기술에 대한 국내 특허출원을 냈기 때문이다. 그런데 문제는 이런 전쟁이 시민의 동의없이 수행되고 있다는 것이다. 우리나라는 현재 생명공학의 경쟁력 확보와 시민적 합의라는 두마리의 토끼를 잡아야 하는 딜레마에 빠져 있는 것이다.

우리나라 여름날씨는 같은 위도 자리의 다른 지역보다 무덥고 기간이 길며 장미와 태풍으로 인한 수해로 해마다 많은 재산과 인명피해를 입고 있다. 우리나라 장마전선은 6월25일께 상륙해 완전히 빠져나가는데 20~25일 걸리며 태풍은 8월 하순에 상륙해 홍수를 몰고와 연례행사처럼 우리를 괴롭히고 있다.

The purpose of this study is to examine cinematic representations of places in the Korean War films on the event of 1950 'Incheon Landing', focusing on the place representations. 'Incheon Landing' of September 1950 provided a turning point for the Korean War, and the event can be interpreted totally different from the South Korean and the North Korean perspectives. Two films on the same event of the 'Incheon Landing' - a South Korean film, "Incheon Landing Operation"(1965), and a North Korea film, "Wolmido"(1982)- were selected as major sources of analysis and comparison. each director has different intentions. One film was taken from the landing army's viewpoint, whereas the other film was taken from the defender's viewpoint. As a result, one film emphasized the battle as a spectacle of glorious victory from the landing army's viewpoint, while the other film glorified those soldiers killed in the battle as heroes from the defender's viewpoint.

Operation Chromite was the first combined landing operation executed by ROK marine corp's and allied forces on Sept 15, 1950. Its historical significance is that it provided Korea with an opportunity to retake capital city Seoul because it helped to fight back from Nakdong river defense Front. During the landing, ROK marine corp's was highly praised from US commanders that "No any defect was found from ROK marine corp's perfect battle performance." and ROK marine corp's spirit of sacrifice with serving our country presented a grant spectacle to all over the world. In these days, the reason why ROK marine corp's gains trust and has grow successfully as national army force is that it prepares national emergency though strong training during peacetime. However, bad tradition like beating and harsh treatment must be fixed. ROK marine corp's should improve and take over the hard earned tradition from former marines and do our best to be trusted from people.
