To investigate the effects of hyperstimulation on the reproductive function, such as number of ovulated oocytes, fertilization rate, rate of blastocyst formation, number of survived implanted fetus, and effect on tubal transfer of embryos, ICR mice were injected intraperitoneally with PMSG, 5 IU and HCG, 5 IU and the comparative study with the control group was undertaken. In addition, mouse embryos, i.e., morulas or blastocysts were transferred to pseudopregnant recipient to investigate whether the embryo stge could effect on implantation rate. The results were as follows: 1. The number of ovulated oocytes after hyperstimulation was significantly increased, compared to the control group. The number of degenerated oocytes was also significantly increased. 2. The fertilization rate after hyperstimulation was not significantly different, compared with the control group. 3. The rate of blastocyst formation after hyperstimulation was significantly decreased, compared to the control group. 4. The number of survived implanted fetus was not significantly different with control group. 5. The speed of embryos’ movement in tube was significantly increased after hyperstimulation. 6. The significant loss of embryos was noticed just before implantation in hyperstimulation group. 7. After embryo transfer to recipient mothers, pregnancy rte with blastocysts was significantly increased, compared to pregnancy rate with morulas. This study suggests that hyperstimulation treatment on mice brings about significant loss of embryos just before implantation and its cause seems to be originated from developmental delay of the embryos.

The modernization of industry structure is rendered to increase the woman's employment. The rate of woman's employment has been rapidly growing in Korea ever since the 1960's industrialization. The enormous number of highly educated woman has been raised while they have little took part in the social activities. It became a new problem of the society. This study, therefore, aims at analysing the female collegians employment consciousness and their career readiness situation in order to develop a program to guide the career course for the girl students of Universities in Korea. The three conceptions of questionaires were designed to investigate the famale students' employment consciousness ; That is, career consciousness, sex role and environmental factor. Such two methods as the O'Neil's Career Factor Check List, and the Spence and Helmerich's Attitudes Towards Women Scale (AWS) were used to recognize them. For a week, the rashly collected 900 girl students at Dong-Guk Univ were sampled, and then 817 responses of them were selected to analyse. χ²-test and one-way ANOVA were carried out to grasp the general characteristics over the matters. At first, the majority of female collegians (97.4%) hoped to get a job. Most of them (77.6%) put more emphasis on marriage than on work. It causes employers to consider that women graduated from the Universities are not progressive either rational. Neither do they get a job easily, nor do they deliberate future, aptitude, and major when they get to work. We can also discover the female collegians' career consciousness is influenced by the attitude toward sex role. Now that the distorted social general idea on the woman employment influences career consciousness, they are being discorded psychologically. This study shows a couple of condusions as followings ; First, no wonder most of female collegians hope to work. Bust the fixed social situation unchanged frustrates many girl students and prevents them from being employed. Secondly, they do not have the obvious and subjective career consciousness. So, they ought to be leaded to a steady and slow preparation for the employment. In order to do so, the college authorities are needed to give students the special or culture lectures in advance. Finally, every kinds of public offices, companies or constitutions have to increase the employment rates of capable women graduated and establish more public day nurseries so that they can manage both marriage and work. Moreover, the introduction to employment by the hour, the prevention of the sex distinction and labor surroundings improvement should be realized as soon as possible.

Applicability of hyperbolic settlement prediction method to consolidation settlement in the dredged and reclaimed ground was assessed by analyzing results of centrifuge tests modelling self-weight consolidation of soft marine clay. From literature review about self-weight consolidation of soft marine clays located in southern coast in Korea, constitutive relationships of void ratio - effective stress - permeability and typical self-weight consolidation curves with time were obtained by analyzing centrifuge model experiments. For the condition of surcharge loading, exact solution of consolidation settlement curve obtained by using Terzaghi's consolidation theory was compared with results predicted by the hyperbolic method. It was found to have its own inherent error to predict final consolidation settlement. From results of analyzing the self-weight consolidation with time by using this method, it predicted relatively well in error range of 0.04~18% for the case of showing the linearity in the relationship between T vs T/S in the stage of consolidation degree of 60~90 %. However, it overestimated the final settlement with large errors if those relation curves were nonlinear.

Ankyloglossaia, or "tongue-tie", is a congenital condition which occurs as a result of fusion between the tongue and the floor of the mouth. The condition can vary in degree from a partial to a complete ankyloglossia. Limitation of movement of the tongue tip results in malocdlusion whth an anterior "open bite" deformity, early prognathism, and swallowing, speech and respiration difficulties. A method of Z-plasty on tongue-tie have been concermed since 1966s. A report of children who have been treated with frenectomy, myotomy & Z-plasty due to ankyloglossia were presented. Generally, lingual frenectomy was used for Tx. of ankyloglossia but extension and relapse were found out fault. In this treatment, we used Z-plasty. as a result we finded out that it is effective for correction of movement limitation of tongue, prevention of relapse, lengthing of mucosal tissue. Further, periodic check up is needed for evalation of relapse, improvement of speech, and other function of tongue.

In this paper stability about lateral soil movement of bridge abutment constructed on the soft ground, reinforced with the sand compaction pile (SCP) and the preconsolidaton methods, was evaluated by using the centrifuge testing facility which stress conditions in field could be reconstructed in the laboratory. The layouts of model such as ground condition, sand compaction piles and abutment was determined on the basis of similitude law with the reduced scale of 1/200. Construction sequences of installing SCP, preparing reclaimed ground, preconsolidating ground and building the piled bridge abutment were reconstructed during centrifuge modelling and measurements of movement were followed in each sequence. From analyzing the results of measuring movements of the model abutment and the ground, measured lateral movement of model abutment was found to be within the allowable value so that stability of abutment against lateral sliding was secured.

Chronic eosinophilic pneumonia(CEP) is a rare disease of unknown etiology characterized by chronic infiltration of the lung with eosinophils. It presents with profound systemic symptoms comprising fever, night sweats, weight loss, dyspnea and blood eosinophilia with nonsegmental air-space consolidation confined to the outer third of the lung, the "photographic negative of pulmonary edema". Histopathologic features of chronic eosinophilic pneumonia are intraalveolar and interstitial infiltrations with eosinophils, histiocytes, giant cells, scattered lymphocytes and plasma cells. Glucocorticoid therapy cause prompt resolution of symptoms as well as disappearans of blood eosinophils, elevated serum Ig E levels and the roentgenographic lesions. Infrequent radiographic findings include nodular infiltrates, consolidations, cavitations, atelectasis and pleural effusions. Deaths from CEP although rare, have been reported, but the majorities of CEP have benign courses and do not need a therapy with ventilator. We report a case of chronic eosinophilic pneumonia, which had a sudden course associated with diffuse pneumonic consolidations on the both lung and bilateral pleural effusion.
