경상북도 영덕군의 하천에 서식하는 점몰개 spotted barbel gudgeon (Squalidus multimaculatus Hosoya et Jeon)의 근육에서 새인두흡충 Clinostomum complanatum (Rudolphi, 1814)의 피낭유충이 발견되었다. 감염된 점몰개는 "yellow grub"인 기생충의 피낭유충으로 인해 표면이 울퉁불퉁하게 보였으며, 수면위에 힘없이 유영하였고 일부 폐사한 개체도 발견되었다. 분리된 탈낭유충의 형태는 혓바닥 모양이었으며, 크기는 2.85~5.89 mm×0.8~1.99 mm였다. 어체당 1~98 개의 피낭유충을 분리하였으며 평균 감염수는 25개로 나타났다. 특히, 성어크기인 평균 7 cm 정도의 점몰개는 100% 감염되어 있었다. 본 연구는 한국의 자연수계에 서식하는 어류에서 C. complanatum 의해 질병이 발생하고 폐사가 일어난 첫 보고이다. The metacercariae of Clinostomum complanatum (Rudolphi, 1814) were isolated in the whole body muscle of wild freshwater fish, spotted barbel gudgeon (Squalidus multimaculatus Hosoya et Jeon) from the local river in Yeongdeok, Gyeongsangbuk-do, Korea. The infected fish with bumpy body surface by "yellow grub" showed erratic swimming behavior and some fish were died. The isolated excysted metacercariae were tongue shaped and 2.85~5.89 mm × 0.8~1.99 mm in size. 1~98 metacercariae were isolated in individual fish and mean infection intensity was 25. All examined adult spotted barbel gudgeon sizing 7 cm in body length were infected. This is the first report of disease outbreak and mortality caused by C. complanatum infection in wild freshwater fish in Korea.

A series of wholly aromatic polyesters with side chains were synthesized by solution polycondensation from 2,5-dialkoxyterephthaloyl chlorides with the corresponding diol. The polymers showed the schlieren textures which is indicative of a nematic phase above their melting temperature. The inherent viscosities (η_(inh)) measured at 35℃ in phenol/p-chlorophenol/1,1,2,2-tetrachloroethane were 0.56-0.98 dℓ/g. The glass transition temperature (T_(g)) and melting temperature (T_(m)) decreased with increasing the length of the alkoxy side chain. Initial decomposition temperatures in TGA occurred at 338 ~ 363℃ in N₂ gas and thermal stability of polymers decreased with increasing the length of the side chain.

열방성 액정중합체와 PEN과의 블렌드에 관한 연구

A new semirigid liquid crystalline polyester(LCP) was synthesized by polycondensation of 2,6-naphthalenedicarbonyl dichloride with the corresponding diol having a hexamethylene group. Blends composed of poly(ethylene 2,6-naphthalate, PEN) were prepared by the coprecipitation from a common solvent. The thermal. mechanical properties and morphology of blends were examined using differential scanning calorimeter(DSC), scanning electron microscope(SEM), and dynamic mechanical thermal analyzer(DMTA). The glass transition ternperature(T_(g)) and the cold crystallization ternperature(T_(c)) of the PEN in the blends decreased with increasing the content of LCP and the LCP acted as a nucleating agent for the matrix polymers. The LCP phases in the blends were found to be finely and uniformly dispersed by SEM micrographs. The modulus of LCP/PEN blends were enhanced on the LCP content increase.

블라우스 한장을 제작하는데에 필요한 시간을 가격으로 환산한다면 도저히 기성의류품에 승부를 겨룰 수가 없을 것 같다. 이와 같은 사회적 배경 속에서 대학에 있어서의 피복교육도 그 내용이 바꿔져야 할 것이다. 곧 가정주부가 되어 직면할 문제 즉 생활필수품은 모두가 주부 자신의 손에서 이루어지는 것이 아니기 때문에 시판되어 있는 상품을 어떻게 잘 이용하는가에 따라 소비적 입장에서의 관리기술도 중요한 요인의 하나라고 생각한다. 따라서 소비생황에도 대처할 수 있는 지도를 해나가는 것도 필요하다. 젊은 연령층에 있어서는 기성의류품을 매력적으로 생각하고 있지만 아직도 고연령층에 있어서는 이용하는 사람이 적은 것 같다. 이러한 원인으로 볼 수 있는 것은 한복을 주로 입는 고연령층과 맞춤옷, 가정양재 등의 분야가 상당히 있다는 배경 그리고 직접적으로는 기성복 업계 자신의 문제 즉 체형형 사이즈의 부족과 기업이 목표로 한 메이커가 젊은 사람 위주로 기울어져 있다는 면, 소매점의 판매정책의 문제 등 여러가지를 들 수 있다. 이러한 문제를 소비자의 소리의 하나로 기업측에 호소하여 업계로 하여금 재고의 기회를 가져 다종 다양한 상품을 제작 시판함으로써 기성복을 원하는 사람들이 보다 합리적인 의생활을 하는데 도움이 되었으면 한다.

This study was designed with the purposes to translate the parent's consciousness of children's room and to produce the basic data for the guidance and the effective preparation of children's room and the children s residing environment in addition, by grasping generally the mother's consciousness of children's room. The subjects were 212 4th-6th grade elementary school children living in Taegu. The data were collected by questionnaire methods and analyzed through SPSS PC program. The major findings are as follows : 1. The greater part of mothers recognized that the children's room is necessarily needed to children. 66 74 among all subjects perceived that the adequate period of sleeping separation from their parents is before the entrance of elementary school. It was found that in the children s hope for the possession of their room from mother's viewpoint, the majority of mothers perceived that their children's very wanted to have their own room. The greater part of mothers perceived that the environmental preparation of children's room have an effect on their personality. And when mothers decide the location of children s room they regarded the natural environment such as sunlight and airing as the most important matter. 2. There were significant differences in the mother's consciousness of the necessity of children's room according to the independent variables such as the conditions of housing possession, mother's educational level. The type of using of children s bedroom was variables according to family numbers, the order of birth, housing style, the numbers of room, environment around residing. The adequate periods of sleeping separation from their parents were significant different in the variables as children's sex, father and mother's educational level. There were significant differences in the consideration for the interior of children's room according to father's occupation, father and mother's educational level. There were significant differences in the effect of the environmental preparation of children's room on children's personality according to only father s occupation.

It was reported that hepatic aldehyde dehydrogenase(ALDH) activity was depressed in alcoholic liver diseases, however there was few report that explain the reason of depressed ALDH activity. We have attempted to correlate the decrease of hepatic ALDH activity with the active oxygen species which generated at elevated rates in the proliferated microsomes by chronic ethanol feeding. The susceptibilities of the hepatic ALDH activity to active oxygen generated by xanthine-xanthine oxidase system and FeSO₄-H₂O₂ system were studied. Incubation of ALDH with 2×10³ xanthine oxidase for 30 min at 25℃ resulted in the decrease of enzyme activity to 60%, and 55% of ALDH activity was retained after exposure to FeSO₄4-H₂O₂ system for 20 min. Alteration in the ALDH activity after administration of ethanol in rat liver was investigated. Whereas the mitochodrial ALDH activity was increased, the microsomal activity was depressed in ethanol-treated rat. Induced microsomal ALDH activity was observed by treatment of phenobarbital or 3-methylcholanthrene in the liver of rats chronically fed alcohol. Since the ALDH catalyses the oxidation of a wide variety of aliphatic and aromatic aldehydes, it is suggested that the alteration in the ALDH activity by various factors including the active oxygen affects the physiological states of liver administrated ethanol chronically, which may in turn to lead to liver disease.
