This study was interested in how different the type pf EEG(Electroencephalograph) is according to the levels of trait and/or state anxiety. Particularly, & respinse of EEG In each anxiety level (high - and low level) was mesaured, and each anxiety level was compared in terms of the ratio of the & wave to the total wave. Two hypotheses were postulated as follows: Ⅰ. & respponse would be different according to trait anxiety level. The ratio of & response to the wave of high anxiety group would be higher than that of low anxiety group in resting situation. Ⅱ. & response would be different according to anxiety level in stressful situation. Junior high school students (48 girls) with the age range of 15 to 16 years were given by questoinnaire to measure the anxiety level. Some items were selected from PIC (the Personality Inventory for Children)and revised for the young students. The upper 10% of the score was selected as high anxiety group (5 girls) and the lower 10% as low anxiety group (5 girls). In both resting - and stressful sityation, EEG was recorded and compaired to both high anxiety - and low anxiety group. The results were that 1) in resting situation, the & response to the total wave on Cz and T3 in high anxiety group was higher than tnat in low anxiety group 2) in stressful situation, & response Cz and T3 in low anxiety group was not any significant change although & response in high anxiety group was increased, and 3)there was not significant difference in & response on O1, known as a part that & response is frequently recorded, in terms of anxiety and experimental condition, These results supported both hypotesis Ⅰ and Ⅱ, and were consistent with the prvious data of Siciliani(1975) and Nowak(1981). The study, as first study to examine the realtionship between anxiety and physiological data, showed that physiological index could be useful in testing of the problems of young students in school.

傳聞法則에 關한 小考

金仁善 順天大學校 1987 論文集 Vol.6 No.1

Hearsay rules are said to be principles of criminal evidence law which can reject the evidence ability in the hearsay evidence and to be prescriptions which can declare, as shown under sub-sectional 2 of section 310 of the criminal procedure Law in korea. What is a hearsay rule is said to be a rule indirectly reporting the experimental facts in other form of an experimentalisits own to the court, and not directly reportion them to the court. The hearsay rule is to be drawn from the principles of evidence law with persons concerned in English-American laws, on the base of our criminal laws on Korea the hearsay rules and the exceptional rules are, what is called, employed under sub-section z of section 24 of the criminal procedure Law, while they include Some problematic points in theory or in business, as there are no direct prescriptions as to what is the nation of hearsay evidence. The purpose of this paper is to present that we can obtain a more helpful interpretation and application from the current Criminal procedure Law, using the prescripions and legal conciousness of korean laws, more elastically, when the hearsay are applied. 'Introduction' is described chapterⅠ, and chapterⅡ, provides the specifications of hearsay evidence; chapterⅢ,the contents of syllogisn of hearsay rules and legislative examples; ChapterⅣ, the theoretical background of hearsay rules ChapterⅤ, the existing value of hearsay rules; and finally chapterⅥ,the applications of hearsay rules and their problems.

We have developed a high-$T_c$ SQUID magnetocardiogram (MCG) system for small laboratory animals. White noise of the measurement system was about 30 fT/$Hz^{1/2}$ when measured in a magnetically shielded room. We optimized the measurement position to obtain clear MCG wave from rat's small heart by using grid measurements. With the optimization, the MCG signal was successfully detected with the peak amplitude of about 30 pT. We could observe well defined P-, QRS-, and T-waves from the rat MCG. The results suggest that the developed system has a strong potential to monitor the progress of the heart disease model by using a laboratory rat.

Microbial Colonization of the Aquatic Duckweed, Spirodela polyrhiza, during Development

김인선,Kim, In-Sun Korean Society of Electron Microscopy 2004 Applied microscopy Vol.34 No.2

수생식물 개구리밥(Spirodela polyrhiza)의 식물체 발달 과정에서 나타나는 미생물과의 상호관계를 주사전자현미경 및 세포학적으로 추적하여 연구하였다. 개구리밥은 부유성 식물로 분화 발달 초기부터 잠수부위에 여러 종류의 박테리아, 남조류, 규조류 등이 서식하였다. 미분화된 어린 식물체에는 성숙 발달한 식물체에 비해 미생물들이 낮은 빈도로 출현하였고, 성숙한 식물체에서는 특히 엽상체 하피에 가장 많은 미생물들이 서식하였으며, 그 다음으로는 점액성 물질이 층을 이루는 근관에 많이 관찰되었다. 반면, 신장 발달 중의 뿌리에는 일반적인 분포를 보였으며, 상피에는 미생물이 거의 분포하지 않는 양상을 보였다. 이들 미생물이 개구리밥 조직 내에 침입하여 식물체에 어떠한 영향을 미치는가를 조사하기 위해 엽상체, 연결사, 뿌리, 근관, 무성생식낭 등의 구조를 세포학적으로 추적한 결과, 어느 부위에서도 조직 내로 미생물이 침입하여 세포를 괴사시키거나 감염시키는 일은 거의 관찰되지 않았다. 그러므로, 개구리밥 식물체의 발달과정에 있어 미생물들은 어떠한 해를 주지 않는 것으로 추정된다. 이후 개구리밥에 서식하는 미생물의 질소고정치를 측정하여 그 기능을 식물체의 세포학적 측면과 접목시켜 연구하면 개구리밥과 미생물과의 상호관계가 공생적인지를 더 확실하게 밝힐 수 있을 것이다. Fresh specimens of the aquatic macrophyte, Spirodela polyrhiza, have been examined employing scanning and transmission electron microscopy. Observations revealed the occurrence of microbial colonization during development. Submerged parts of the small, free-floating S. polyrhiza body exhibited a variety of microorganisms such as bacteria, cyanobacteria, and diatoms throughout their development. However, immature and/or young plants normally demonstrated much less microbial colonization compared to mature plants. During the study, heavy colonization by the microorganisms was routinely encountered at maturity, especially in the fully developed abaxial fronds and root caps. The mucilaginous layer was shown along the root caps, and the microorganisms appeared to be either clustered or attached to this layer. In contrast, only moderate degrees of colonization were observed in the root, and little to no colonization was observable in the adaxial frond surface. Transmission electron microscopy clearly demonstrated the microbial colonization to be external in the S. polyrhiza specimen examined in the current study. The association between the microorganisms and S. polyrhiza has been considered non-harmful, as no frond senescence and almost no mechanical penetration of the plant by the microorganisms were noticed during the study.

수생형 통발(Utricularia japonica)의 흡입식 포충낭 형태 연구

김인선,Kim, In-Sun 한국현미경학회 2010 Applied microscopy Vol.40 No.2

본 연구에서는 뿌리 없이 분지된 줄기에서 기원한 포충낭으로 먹이를 빠르게 포획하는 수생형 통발 포충낭의 형태 구조적 특징을 전자현미경으로 연구하였다. 이들의 흡입식 포충낭에서는 입구 부위 및 덧문에 발달하는 구조들이 능동적 먹이 포획에 있어 다른 어느 구조보다도 중요한 기능을 수행할 수 있도록 분화되어 있다. 포충낭 입구에는 분지된 안테나 및 부속지들이 위치하고, 덧문 중앙 부위에는 4개의 감각모가 발달하여 먹이의 접촉자극을 감지하였다. 자극신호는 입구의 무병, 유병의 다양한 capitate형 분비모들이 소수성 점액물질을 분비하게 하여 이들을 피복하며 덧문을 닫아 먹이를 포획하였다. 덧문 안쪽의 threshold는 입구부분, pavement epithelium 층, 내부 구역으로 구분되며, 입구와 내부구역의 중간에 있는 pavement epithelium 층에는 소수성 큐티클이 피복된 밸름층이 형성되었다. 먹이가 포충낭의 내강으로 들어오면 내벽에 발달하는 2분지선과 4분지선들이 효소 등의 물질을 분비하여 이들을 소화 및 흡수하는 중요한 기능을 하였다. 이와 같이 통발의 흡입식 포충낭에서는 안테나, 감각모, 덧문, capitate형 분비모, 내벽의 분지선 등이 체계적이고 효율적인 방법으로 그 구조와 기능이 분화되어 식충의 기작을 수행하였다. 이후 포충낭의 분화발생을 생장단계별로 추적 연구하여 본 연구의 결과에 접목시키면 더 유용한 통발속 포충낭 구조 자료가 될 것이다. Morphology and microstructure of the suction trap in aquatic Utricularia japonica were examined using scanning electron microscopy. Branched stems bear numerous suction traps without root formation. The traps are derived axillary from the node, and their antennae and appendages extend in a peculiar fashion. The trap walls are thin, two-celled, parenchyma tissue and simple, small glands are scattered in both internal and external surface of the trap. The entrance of the trap is surrounded by one pair of dorsal antennae and ventral appendages, where the former guides the prey to the entrance. Trap door is situated below the entrance and numerous sessile and stalked capitate trichomes cover the entrance and even on the door surface. The capitate trichomes are secretory, but four trigger hairs formed on the central areas of the door are not. They are believed to function in activating and tripping the trap door. A specialized region of the threshold come in contact with the lower portion of the door upon closing. The secretory capitate trichomes near this region are responsible for producing and secreting a mucilage-like substance which composes the velum. Two-armed bifid glands are located in the interior side of the threshold, while four-armed quadrifid glands are considerably numerous occurring over the entire inner trap wall. Bifid and quadrifid glands develop semi-spherical basal cells that connect them to the inner wall surface. Antennae, trigger hairs, capitate trichomes, bifid and quadrifid glands are more important structures in the carnivory of U. japonica.

High-$T_c$ SQUID 자력계를 이용한 자기잡음 환경에서의 미세자기신호 측정 및 분석

김인선,유권규,박용기 한국초전도학회 2003 Progress in superconductivity Vol.4 No.2

The single layer direct-coupled YBCO SQUID magnetometers have been fabricated and characterized for the purpose of the measurement of weak magnetic signals in unshielded environment. Two types of magnetometers have been designed and fabricated using 10 mm$\times$ 10 mm substrates. We could operate the conventional 3-mm-wide solid pickup loop magnetometers more stably than the 12-parallel-line pickup loop magnetometers in laboratory environment. We developed a first-order electronic gradiometer system using the SQUID sensors with axial displacement of 80 mm without any mechanical alignment of magnetometers. The system with a software filter using calculation of discrete Fourier transform could record clearly weak pulse signal of 100 pT in a magnetically disturbed environment.
