A branchial parasitic bopyrid, Parabopyrella elongata (Shiino, 1949), is newly recorded in Korean fauna. Parabopyrella elongata differs from its congeners by the following characteristics: the head is smooth anteriorly in females; the pleon of females has distinct and wide lateral indentations on both sides; the pleotelson has a rounded distal end in females; oostegite 1 has a rounded posterolateral point; the pleon of males is single-segmented; and the uropod is absent in males. In this study, the detailed description and illustrations of the species are presented with an emended key to known Parabopyrella species in the Far East. The variations in P. elongata were also discussed. This is the first report of the genus Parabopyrella from South Korea.

Objectives: The purpose of this study is to report bowel sound patterns recorded in 3 diseases associated with structural deformity of the pylorus-duodenum. Methods: : Bowel sound recording is a useful non-invasive tool for the evaluation of gastrointestinal motility. However, the difficulty in manual attachment of the electronic stethoscope on the abdominal wall and noise production against bowel sound signals have prohibited its widespread use. Therefore, I developed a new apparatus that eliminates the noise; it contains a sound absorbing device and a holder for the head of stethoscope. Using the new bowel sound recording system, bowel sounds of the patients were recorded repeatedly. The endoscopic and abdominal computed tomography findings were obtained from other hospitals' medical record, and all patients were confirmed to have structural deformity in the pylorus-duodenum. The records of each patient were compared and assessed. Results: : Patients had either duodenal ulcer scar, pyloric stricture, or far advanced malignant stomach cancer, as diagnosed by the gastroscopy. Their dominant frequency of bowel sound obtained from the new system was checked more than 2 times at regular intervals. All 8 recordings in the 2 patients with duodenal ulcer scar (5 times) or pyloric stricture (3 times) showed a decrease in postprandial than fasting dominant frequency. One patient with stomach cancer showed no significant change between postprandial and fasting states at 2 recordings. Conclusions: The analysis of dominant frequency in bowel sounds can indicate the existence of pyloric obstruction that could delay gastric emptying.

Development of hospital information system and Picture Archiving Communication System is not new in the medical field, and the development of internet and information technology are also universal. In the course of such development, however, it is hard to share medical information without a refined standard format. Especially in the department of radiology, the role of PACS has become very important in interchanging information with other disparate hospital information systems. A specific system needs to be developed that radiological reports are archived into a database efficiently. This includes sharing of medical images. A model is suggested in this study in which an internal system is developed where radiologists store necessary images and transmit them in the standard international clinical format, Clinical Document Architecture, and share the information with hospitals. CDA document generator was made to generate a new file format and separate the existing storage system from the new system. This was to ensure the access to required data in XML documents. The model presented in this study added a process where crucial images in reading are inserted in the CDA radiological report generator. Therefore, this study suggests a storage and transmission model for CDA documents, which is different from the existing DICOM SR. Radiological reports could be better shared, when the application function for inserting images and the analysis of standard clinical terms are completed.

We report the case of a 22-month-old boy with a new mosaic partial unbalanced translocation of 1q and 18q. The patient was referred to our Pediatric Department for developmental delay. He showed mild facial dysmorphism, physical growth retardation, a hearing disability, and had a history of patent ductus arteriosus. White matter abnormality on brain magnetic resonance images was also noted. His initial routine chromosomal analysis revealed a normal 46,XY karyotype. In a microarray-based comparative genomic hybridization (aCGH) analysis, subtle copy number changes in 1q32.1-q44 (copy gain) and 18q21.33-18q23 (copy loss) suggested an unbalanced translocation of t(1;18). Repeated chromosomal analysis revealed a low-level mosaic translocation karyotype of 46,XY,der(18)t(1;18) (q32.1;q21.3)[12]/46,XY[152]. Because his parents had normal karyotypes, his translocation was considered to be de novo. The abnormalities observed in aCGH were confirmed by metaphase fluorescent in situ hybridization. We report this patient as a new karyotype presenting developmental delay, facial dysmorphism, cerebral dysmyelination, and other abnormalities.

The writer presented in the report 7th of this series(Chong, 1959. '62 a.b. '64, '65) the result of fertlizer application on Sasamorpha purpurascens var. borealis with regards to soil conditions, climate, planting position etc. and this report is on the effectiveness of fertilizers by kinds of the new (1-year old) and old(3-to 4 years old) Phyllostachys retticulata. The ineffectiveness of fertilizers for old bamboos aged more than 8-years old has been reported previously. The study site was chosen in a bamboo groven situated at Hyunnae Ri, Okkye Myun, Myungju Gun, Kangwon Do. Each plot was so designed that only one individual remained at the center of a circular area with a dimeter of meters by eliminating the clums and severing the rhizomes, of other individuals around it. And, for the fertilizer test, 10 individuals(the new and old: 5 to 5) were observed per kind of fertilizer used; thus marking the total number of 160 plots in all. The second part of this study was conducted for the potted individuals which numbered 48, successfully established ones out of 55 the transplanted to pots. The 48 were divided into 8 treatments: whole fertilization (NPK＋compost＋human manure); NPK; N; K; Human manure; compost; and the control. Amoung of fertilizers applied was 200 grams for the natural plots and 100 grams for pot; it continued for 3 years and applied twice a year (spring and summer) following the theory of Dr. Koichi-ro Ueda(1954, '60 a.b.). Measurements were taken in August each year. The resutls were confirming the fact that the bamboos require a great deal of fertilizers. The results show the following points: 1) Fertilizers were more effective in the 3 to 4 year old bamboos. 2) The order of effectiveness of fertilizers by kind was the whole fertilization, NPK, and N treatments for Phyllostachys reticulata. 3) Organic matter in addition to commercial fertilizers showed better result than the soil application of the latter due to better soil aeration.

Cancer is the second leading cause of death in the world. According to the 2018 reports, one in six people worldwide is reported to die as a result of cancer. The discovery of anticancer drugs has been utilized extensively, but there has been no report on excellent selective activity in cancer cells. The discovery of bioactive substances from marine sponges has been the limelight in the pharmaceutical field over the past decade owing to the production of many bioactive compounds from the sponges to protect themselves against the environment. On top of that, marine sponges also produced cytotoxic compounds such as terpenoids, alkaloids, steroids, and peptides which suggests that marine sponges have high potential in the development of anticancer drugs. Thus, this study aimed to obtain new cytotoxic compounds from S. siphonella in Egypt and Arenoscelra sp. and Gelliodes sp. in Vietnam, and further investigation of the extract from these marine sponges led to isolation of ten new compounds and 21 known compounds. Chapter 1 will discuss about the isolation and structure elucidation of eight new polyacetylene derivatives from S. siphonella and their cytotoxic activities. The isolation and structural elucidation of one new polybrominated iododiphenyl ether from Arenosoclea sp. as well as cytotoxic activities of the isolated compounds will be reported in chapter 2. Finally, isolation and structure elucidation of new compounds from the marine sponge Gelliodes sp. and their cytotoxic activities will be discussed in chapter 3.
