The air-sea relations in the northern sea of Cheju Island have been stidied through the observations on Ham-duck area. The oceanic circumstances are basically affected by the adjacent seas, specially the East China Sea. Seasonal tempreature changes let us make sure that the Kuroshio waters are extended to the north-west direction in winter and shrinked to the south-east direction on summer. In addition, Ham-duck area shows some air-sea relations, such as closely related dir and sea surface temperatures, and effects of precipitations on surface salinities. the temperature and salinity distributions in the coastal areas also reveal probably upwellings by the east winds, However, the monthly observations of planktons and fishes make it hard to find any effects of these oceanic changes, which are primarily due to the atmospheric conditions, on the biological productions.

본 논문은 발달장애유아 언어행동발달 컨텐츠 개발에 요구되는 기초연구로써 연구의 이론적 바탕을 확립하고자 하였다. 연구에 사용된 방법은 문헌조사 방법 및 현장 인터뷰기법을 병행하였다. 본 연구의 주된 목적은 크게 3가지로 구분된다. 첫째, 발달장애유아의 가정 내 교육 욕구를 분석하고자 하였다. 둘째, 발달장애유아의 언어발달 양상을 검토하고자 하였다. 세 번째 목적은 유아의 언어행동발달 컨텐츠 구성의 주요 지침을 설정하고자 하였다. 이상의 연구목적에 따른 연구결과를 요약하면 다음 몇 가지로 제시된다. 1.가정 내 부모-유아간 관계형성이 우선 고려 되어야하고, 이에 따른 상호작용은 발달적 애착형성이 가능한 방향으로 정립되어야한다. 2.발달장애유아의 언어행동발달양상을 검토한 결과에 따르면, Piaget는 언어행동발달에 있어 감각운동기적 환경탐색 기능을 강조하고 있고, 이는 현재까지 중요한 유아 발달의 기저로 정착되었다. 따라서, 발달장애유아의 언어행동발달을 위한 컨텐츠 개발 내용에 있어서도 이러한 기저에 충실함이 합리적이다. 3.발달장애유아들에게는 언어행동 양상의 갈래가 크게 운동장애 및 감각결함으로 나누어질 수 있으므로, 이 두 가지 갈래의 각기 다른 특성이 컨텐츠 구성에서 충분히 고려되어야한다. 4.자폐성과 같은 중증 전반적 발달장애 유아를 위한 언어행동발달 컨텐츠 구성에서 특히 고려해야 할 두 가지 요소는 모방행동기능과 반복단순훈련기능 향상으로 결론지을 수 있다. This article planed to establish the theoretical foundations of the research as a basic study needed for developing the contents of verbal(language) behavior development for the infants with developmental disabilities. The methods used in the study was previous literature researches and interviews with subjects. The purposes of the study were divided into three parts. First, it was to analyze the educational needs of the infants with developmental disabilities in home settings. Second, it was to review and discover the language patterns of the infants with developmental disabilities. The third purpose was to devise the major guidelines of their language development's contents. The results of the study were described as the followings. 1.The relationships between the infants with developmental disabilities and their parents and their interactions should move to build the developmental attachments between them. 2.According to the literature findings of their language development patterns, Piaget concentrated on the functions of sensory motor environmental exploring in the language behavior development. The functions have been settled down into the important foundation for the infants' development. Thus, it was resonable that the content's development of the language behaviors for the infants with developmental disabilities should based on the function addressed by Piaget. 3.The language behaviors' patterns of the infants with developmental disabilities generally were classified into motor disabilities and sensory defect(deficiency). Therefore, the two factors should be considered for the constructions of the contents. 4.Constructing the contents of the language behavior developments for the infants with severely pervasive developmental disabilities such as autism, the improvements of two functions, imitative behavior and repetitive simple training should be considered.

This study has been carried out to determine the effects of bridging liquid concentrations, agitation time, agitation speed, pulp density, and viscosities of the bridging liquid on growth of the agglomerates by agitating the suspension with bridging liquid which preferentially wets the carbon particles. The results of this experiment are as follows : 1) As larger amounts of bridging liquid are used, the size of agglomerates are increased until the end of the capillary region of pore filling after which there is an excess of bridging liquid. 2) At the initial stage of the agitation, the size of agglomerates are increased while after a certain agitation period, the size of agglomerates are decreased because destructive force is increased by frequency of collisions between the agglomerates themselves and their adhesion to the walls of the vessel. 3) The diameter of the final agglomerates are determined by a balance between destructive and cohesive forces acting on agglomerates.

Background and Objectives: Immunolabelling of interstitial Cajal(IC) cells in the intestinal wall has recently been developed by using a specific marker, the anti-c-Kit antibody. Substance-P is a well-known neurotransmitter in the gastro-intestinal tract. Since the gastro-intestinal wall structures have already been well documented in the guinea pig, immunohistochemistry was done for the c-Kit-positive IC network and substance-P receptor(NK1R) in an attempt to provide a morphological basis for the mechanism regulating gastro-intestinal movement. Materials and Methods: Cryosection and whole-mount preparations of guinea pig small intestine and colon were single and double immunolabelled using the anti-c-Kit and NK1R antibodies. Immunolabelled specimens were observed under a confocal laser scanning microscope. Results : According to a three dimensional reconstruction study, it was found that (1) the c-Kit-positive celluar networks were widely distributed in the intestinal wall, (2) c-Kit-positive celluar networks encircled the ganlion, with strands in reticular configurations, and (3) the c-Kit-positive cells showed colocalization with NK1R in circular muscle(CM), not myenteric plexus(MY). Conclusion: The charateristic profiles of IC containing c-Kit-positive celluar networks and the relationship between c-Kit-positive and NK1R-positive structures provide a morphological basis upon the mechanism regulating gastro-intestinal motility.

朴東秀,金裕榮,金庚燦 慶北大學校 1980 論文集 Vol.29 No.-

Achieving high output power in N_2 laser, we used fast electric discharge (~10 nsec), large volume (~0.2 liter) and homogenized discharge. In order to perform the fast discharge, we have designed a lasing cavity driven by TE-type transmission lines and low inductance spark gap, and utilized multiple transmission lines to provide increased lasing volume. Multiple lines should effect on reducing the line impedance. We have derived the good homogeneity of laser discharge from the uniform spatial distribution of the initiating electrons provided by the preionizer. Present work enabled the stability of the main glow discharge relatively insensitive to the surface quality of the main electrodes.

한충수,김유호,강태환,조성찬 한국산업식품공학회 2003 산업 식품공학 Vol.7 No.1

겨울철 곡온이 낮은 현미는 조직이 단단해져서 정맥시간이 길어지고, 과부하로 인해 도정효율 저하와 소비전력량이 증가한다. 조질은 곡물의 함수율과 곡온을 조절하는 기술로써, 현미의 단단한 조도정수율 및 도정효율을 향상시킬 수 있다. 본 연구에서는 저온 현미 정백시 도정효율 향상 및 품질유지를 위해 적정 현미 조질온도와 정백 후 백도, 강도, 동할미율, 싸라기율, 곡온 상승, 함수율 변화, 소비전력량 등과의 관계를 규명하였다. 현미 조질 곡은 0, 3, 5, 12, 20℃에 대한 정백후 백미 백도 변화는 큰 차이가 없는 것으로 나타났고, 동할미율, 완전립과 동할립 강도 및 싸라기율은 현미 조질 곡온이 높을수록 감소하는 것으로 나타났다. 조질 곡은 12, 20℃인 경우가 정백 후 적정 곡온 상승 규정범위 15℃ 내에 해당되었다. 정백 후 함수율 변화는 조질곡온에 관계없이 외기온도와 정백 후 곡온 차이로 발생한 결로에 의해 미세하게 증가하는 경향을 보였다. 정백 소비전력량은 조질곡온이 0℃보다 높은 조건이 2.52~14.28% 감소하는 것으로 나타났다. 따라서 동절기 정백시 현미의 적정 온도는 10℃ 이상으로 조질하거나 유지하는 것이 적절한 것으로 판단된다. This study was find out the relationships between whiteness, hardness, crack ratio, broken rice ratio, increased grain temperature, moisture content, electric energy consumption, and optimum conditioning of grain temperature for milled rice efficiency and quality maintenance during the milling process of brown rice at low temperature. There was no significant difference between the whiteness variations of white rice after milling process when the conditioning grain temperatures ranging from 0 to 20℃ was used. The crack and broken rice ratios of white rice and the hardness of brown rice decreased with an increased in the conditioning grain temperature. Conditioning grain temperatures of 12, 20℃ are applicable to appropriated standard of temperature (15℃) after milling process. In the case of low temperature of grain, there was steadily increase the rate of change moisture contents because of dew condensation. There was 2.62∼14.28% decline of electricity energy for milling process when temperature of grain was higher than 0℃. Therefore it needs to control temperature over 10℃ for appropriate milling in the winter season.

Thrombotic thrombocytopenic purpura (TTP) is a life-threatening syndrome characterized by the classic pentad of clinical features that includes microangiopathic hemolytic anemia, thrombocytopenia, neurologic abnormalities, fever, and renal dysfunction. Early diagnosis and utilization of plasmapheresis can improve the survival rates of patients with TTP. TTP rarely may be seen in association with autoimmune disease such as systemic lupus erythematous (SLE). We report here a 42-year-old female who was presented with severe digital gangrenes, microangiopathic hemolytic anemia, thrombocytopenia, neurologic abnormalities, fever, and renal dysfunction. Her condition responded to combined therapy with high dose steroid, immunosuppressants, and plasmapheresis therapy.
