본 논문에서는 펄스레이더를 이용한 차량검지 알고리즘을 제안하였다. 제안된 알고리즘은 likelihood개념을 이용한 likelihood ration를 통해 하나의 펄스신호에서 분류위치를 추출하고 추출된 분리점을 기준으로 신호를 분리, 간략화 하였다. 이렇게 처리 된 펄스신호에서 연속된 신호의 유클리드거리를 이용하여 단순 군집 탐색 알고리즘에 의해 차량을 검지하였고, 실험을 통해 제안된 알고리즘의 유용성을 확인하였다. This paper presents a vehicle detecting algorithm using microwave system signals. The Proposed algerian decides the breakpoint of signals using the likelihood criteria. The decided signals are segmented and simplified. The proposed searching algorithm uses the Euclid distance from the weighted signal data. We tested the proposed algorithm to compare with the segmentation which is a method using smoothing and edge detection. We confirm that the proposed algorithm is very useful for detecting vehicles by field test.

제주도의 지질과 화산활동에 관한 연구 (I): 동부지역 저지대 시추코어 화산암류의 암석화학 및 $^{40}Ar/^{39}Ar$ 절대연대
고기원,박준범,박윤석,Koh, Gi-Won,Park, Jun-Beom,Park, Yoon-Suk 대한자원환경지질학회 2008 자원환경지질 Vol.41 No.1
제주도 동부 저지대 (해발 200m 이내), 한동-종달-우도-수산-삼달-하천 지역의 20개 시추공에서 얻어진 화산암류의 암석학적 특징과 $^{40}Ar/^{39}Ar$절대연대를 보고하고, 이에 근거하여 이 지역의 지형형성과 화산활동에 대해 고찰한다. 이 지역의 지하에 분포하는 화산암류는 주로 현무암류(알칼리 현무암, 전이질 현무암, 솔리아이트질 현무암)와 솔리아이트질 안산암 및 현무암질 조면안산암으로 구성된다. 솔리아이트질, 전이질 및 알칼리암류가 서로 호층을 이루어 분포하는 것은 이 지역에서 이들 화산활동이 동시에 일어났었음을 지시한다. 특히, 조면현무암 혹은 현무암질 안산암이 이 지역의 기저부에 분포하는 점은 비교적 분화된 알칼리 화산활동이 먼저 시작되었음을 의미한다. 이 지역에 분포하는 화산암류의 $^{40}Ar/^{39}Ar$ 절대연대는 최고 $526{\pm}23Ka$에서 최저 $38{\pm}4Ka$이다. 동부 지역 저지대에서 용암류의 분출과 같은 하와이형 화산활동은 퇴적층의 관계, 화산암류의 전암 화학성분 및 $^{40}Ar/^{39}Ar$ 절대연대의 변화로 부터 다섯 단계로 구분된다. 즉, 서귀포층이 퇴적할 동안의, I-U기$(550{\sim}400Ka)$, II기$(400{\sim}300Ka)$, III기$(300{\sim}200Ka)$와 퇴적 이후 IV기$(200{\sim}100Ka)$, V기(100Ka이후)이다. 화산암류의 성분 변화 및 분포 지역의 차이 그리고 이들 시기 간에 분포하는 다양한 퇴적층(수성화산기원퇴적층 포함)의 존재는 화산활동이 오랜 기간 동안 간헐적으로 진행되었으며, 저지대의 육지지형이 화산활동 및 퇴적작용에 의해 내륙에서 해안으로 점진적으로 확대되면서 만들어졌음을 지시한다. 특히 시추코어 화산암의 $^{40}Ar/^{39}Ar$ 절대연대 자료는 제주도 동부 저지대 지역 대부분이 IV와 V 화산활동기 동안 분출된 200Ka 이내의 비교적 젊은 화산암류로 이루어져 있음을 지시한다. 이는 제주도 화산활동 시기 및 지형 형성에 대한 기존의 연구와는 상이한 결과이며, 화산암류의 K-Ar절대연대 자료를 바탕으로 한 기존의 제주도 화산활동 시기 구분이 재고되어야함을 확인하였다. 또한, 시추공에 근거한 화산 층서의 해석은 암석기재, 암석화학적 특징과 함께 절대연대 자료를 바탕으로 이루어져야 함을 강조한다. This study presents petrochemistry and $^{40}Ar/^{39}Ar$ absolute ages of subsurface volcanic rock cores from twenty(20) boreholes in the eastern lowland (altitude loom below) of Jeju Island, Handeong-Jongdal-Udo-Susan-Samdal-Hacheon areas, and discusses topography and volcanism in the area. The subsurface volcanic rock cores are mainly basalts in composition with minor tholeiitic andesites and basaltic trachyandesites. Sequences of intercalated tholeiitic, transitional and alkalic lavas suggest that tholeiitic and transitional to alkalic lavas must have erupted contemporaneously. Especially, occurrences of trachybasalts and basaltic trachyandesites at the bases in the area imply that the volcanism in the area was initiated with slightly differentiated alkaline magma activity. The $^{40}Ar/^{39}Ar$ absolute ages of the subsurface volcanic rock cores range from $526{\pm}23ka\;to\;38{\pm}4Ka$. The lava-forming Hawaiian volcanic activities of the eastern lowland can be divided into five sequences on the basis of sediment distribution, whole rock geochemistry and $^{40}Ar/^{39}Ar$ absolute ages of the subsurface volcanic rock cores; stage I-U$(550{\sim}400Ka)$, stage II$(400{\sim}300Ka)$ and stage III$(300{\sim}200Ka)$ during syn-depositional stage of Seoguipo Formation, and stage IV$(200{\sim}100Ka)$ and stage V(younger than 100Ka) during post-depositional stage. In the eastern lowland of Jeju Island, compositional variations and local occurrences of the subsurface volcanic rocks as well as existences of various intercalated sediment layers (including hydrovolcanogenic clasts) suggest that the volcanism must have continued for long time intermittently and that the land has been progressively glowed from inland to coast by volcanic activities and sedimentation. It reveals that the subsurface volcanic rocks in the eastern lowland of Jeju Island must have erupted during relatively younger than 200Ka of stages IV and V. The results of this study are partly in contrast with those of previous studies. This study stresses the need that previous reported volcanic activities in Jeju Island based on K-Ar ages of volcanic rocks should be carefully reviewed, and that stratigraphic correlation from boreholes should be conducted by quantitative criteria combined with petrography and petrochemstry as well as radiometric studies of volcanic rock cores.

This paper is about the attitude on the diplomacy and national security of Koreans living in Thailand. The main purpose of this is to examine the consciousness of the diplomacy and national security, and the research took two weeks from February second to twenty-first for the Koreans living in Thailand. The survey is made of 35 questionnaires and the target of the survey is under fourteen years old girls and boys as a random sampling. The contents of this survey are based of historical perceptive, national view, unification diplomacy and the awareness of national security. In the case of the multiple-choice test, the sampled data is processed by SPSS PC+(ver 11.5) which is a statistical package of 366 persons' questions, and includes editing, coding, keying-in and programming for the logicality of answered contents and thoroughly examination. Each item has analyzed by Percentage, Mean, Standard Deviation. And also, in the case of subjective test, each item is analyzed its Percentage by processing of the logicality, scope examination of answered questions, and the terminology similarities. The firm result according to the survey is as follows. First, it is high in the field of the awareness of historical perceptive, ownership awareness, the pride as a Korean. But it is still quiet low in the field of civil workers and foreign policy of Koreans. Second, The Koreans living in Thailand have the high necessity of the unification education, foreign diplomacy and security, but the effect and method of the education are not satisfied. Third, The Koreans living in Thailand aware that North Korean have the mutuality relationship with them. They have the sprit of self-sacrifice for the need and compensation of the unification, and also have the high sympathy about the unification owing to the expectation level for the future unification Korea. As reference, it is master's thesis written in Thailand as a Korean summary paper staying in the Thai National Defense's University and Burapha University when selected for the Korean Government Overseas Fellowship. So it would be a little bit different from the original paper, and the result of this thesis reflects for the real policy research of the related bureau.

Purpose: We investigated the influence of the location of the partial renal vein obstruction on the left kidney, the bilateral testes, and cauda epididymal sperm quality and determined whether this animal model is suitable for varicocele study. Materials and Methods: A total of 25 adult male Sprague-Dawley rats were assigned to three groups: group 1 (experimental varicocele by partial ligation medial to the internal spermatic vein for 8 weeks, n=8), group 2 (partial ligation lateral to the internal spermatic vein for 8 weeks, n=10), and group 3 (sham operation for 8 weeks, n=7). Rats in groups 1, 2, and 3 underwent a left nephrectomy and bilateral orchiectomy at 8 weeks after the operation. Histological changes and Johnsen score in both testes were analyzed. Fibrotic changes in the left kidney were assessed by quantitative image analysis. Numbers of sperm and proportions of motile sperm in the cauda epididymides were determined. Results: Significant histological abnormalities and Johnsen score changes were observed in the testes in group 1. Renal fibrosis did not differ significantly among the groups. The proportions of motile sperm were significantly lower bilaterally in group 1 than in groups 2 and 3. However, the mean bilateral epididymal sperm count in group 1 was not significantly lower than in groups 2 and 3. Conclusions: Our results showed that experimental varicocele in the rat, induced by partial ligation medial to the internal spermatic vein, influences epididymal sperm quality without harmful effects on the left kidney. The present study certifies that this traditional animal model is suitable for varicocele research.
