Investigation on the appendices was carried out to acquire teaching materials about improvement of a appendices and development of teaching-learning activities for science textbooks in Korean middle schools. We analysed the appendices for 30 kinds of science textbooks used in Korean middle schools during $1969{\sim}1994$ years. In the results there were three kinds of pattern for the appendices, such as appendix, non-appendix, and similar appendix without appendix title. The content of appendices were summarized as six categories. such as list of science and scientist history, SI unit-constants and symbols, handling methods of instruments for basic experiments, measuring methods and inquiry activity, safety and precautions, and supplementary data with figures and tables. The appendices of six categories were mostly a content of general and integrated science, and were concentrated in the first grader's textbooks. There were many appendices about the methods for basic experiments such as 'How to Use of Experimental Appliances' in the first grader's science textbooks, but there was no or lack of them in the second and the third grader's science textbooks in the middle school. By the ratio to the pages of appendices which were included according to curriculum changes. the ratio was found to be 4.47% which was the highest in middle school science textbooks at the second curriculum and to be 3.47% which was the highest in high school biology textbooks at the second curriculum. The results of this study indicated that the science textbooks should include as many appendices as possible, because teachers could utilize them in teaching activities and students should be able to be given much help in self-learning.

This study has been conducted to investigate the mating behavior, time sequence of mating and time limit with which female can fulfill spawning and brooding after pre-spawning molting in the giant fresh-water prawn, macrobrachium rosenbergii reared in the laboratory. the results obtained were summarized as follows. Mating happened spontaneously as the following sequences: courting gesture, seizure of female by male, mounting, turning of female, copulation. The entire mating lated approximately seven minutes. The endopodite of 2nd pleopod of male bore the appendix masculins whcih are male's secondary sex characteristic. cinciulli was formed at the distal portion of appendix interna which are on the upper portion of appendix masculins and helped stabilizing the connection of each side of 2nd pleopod during mating. After the connection of each side of 2nd plepod was fixed on the posterior portion of the thoracic sternum in female, a gelatinous spermatophore that emitted at the basipodite of 5th pereiopod during courting gesture was deposited on the ventral groove of 2nd, 3rd, 4th and 5th pereiopod. time limit which female can fulfill copulation and brooding was from 3 hours to 15 hours after pre-spawning molting.

We report the case of a seven-year-old boy with an ingested foreign body, which was retained within the appendix for a known duration of ten months, ultimately requiring appendectomy. The ingested foreign body was incidentally discovered by abdominal x-ray at an emergency room visit for constipation. Despite four bowel cleanouts, subsequent x-rays showed persistence of the foreign body in the right lower quadrant. While the patient did not have signs or symptoms of acute appendicitis, laparoscopic appendectomy was performed due to the risk of this foreign body causing appendicitis in the future. A small metallic object was found within the appendix upon removal. This case highlights the unique challenge presented by foreign body ingestions in non-verbal or developmentally challenged children and the importance of further diagnostic workup when concerns arise for potential retained foreign bodies.

This experiment was performed to evaluate the ultrastructural responses of the absorptive cells in the appendix of the mouse, inoculated with Ehrlich carcinoma cells in the inguinal area, following administration of BCG (Bacillus Calmette-Guerin). Healthy adult ICR mice weighing 25 gm each were divided into normal and experimental groups (experimental control group and BCG treated group). In the experimental groups, each mouse was inoculated with $1{\time}10^7$ Ehrlich carcinoma cells subcutaneously in the inguinal area. From next day after inoculations, 0.5mL of saline or BCG (0.5 mL/25gm B.W.: $0.03{\times}10^8{\sim}0.32{\times}10^8CFU$) were injected subcutaneously to the animals every other day. The day following the last injection, each mouse was sacrificed. Pieces of the tissue were taken from the appendix, prefixed with 2.5% glutaraldehyde-1.5% paraformaldehyde solution, followed by post-fixation with 1% osmium tetroxide solution. The ultrathin sections were stained with uranyl acetate and lead citrate. In the normal control, experimental control and BCG treated mice, general morphology of the absorptive cells of appendix were similar. But myelin figures and intramitochondrial dense granules were more frequently observed in the absorptive cells of BCG treated mice than normal control ones. Above results show that BCG did show slight ultrastructural alterations in the absorptive cell of the appendix. These results that BCG may slightly suppress function of the absorptive cells of the appendix.
