  • The aim of this study is to look at how pepper was used in traditional medicine. In other words, this study aims to take a look at the process by which the medicinal nature & efficacy of pepper in traditional society was perceived and arranged through the aspects of the use of pepper as an exotic crop for treating diseases. This study investigated cases of using pepper for medical treatments by referring to books on traditional medicine in Korea. The old records about pepper are mainly in empirical medical books from the late Chosun dynasty. Nevertheless, the records about pepper tend to decrease in medical text as time goes by. Such a phenomenon can be attributable to the fact that people began to use pepper for daily food life rather than for medicinal purposes. Pepper was used mostly for digestive trouble such as vomiting, diarrhea, and stomachaches, and it was also applied to mental and aching diseases caused by the sound of body fluids remaining in the stomach. In addition, there were many cases where pepper was used externally for surgical disorders. Such symptoms for treatment are linked to, or in a complementary relationship with, research results in modern times. Boiled pepper was generally taken in the traditional herbal decoction method, and in the case of surgical diseases, it was applied externally. The cases of using old pepper, using pepper with seeds or without seeds, and using pepper mixed with sesame oil belong to a sort of herbal medicine processing, which usually aimed at changing the medicinal nature of pepper. In addition, in relation to the eating habits at that time, pepper was used as seasoning and to make red pepper paste with or without vinegar. There are two words used for pepper in the medical textbooks, 苦椒 (gocho) and 烈棗 (yeoljo). These words are translated into Korean as gochu, so we can identify this word as a nickname for pepper.

  • Purpose : This study was to identify the incidence, trend, and situation of the unexpected sudden death of elementary, middle, and high school students in school for 17 years from 1988 to 2004 in seoul. Methods : We used the data of The Seoul Safety Mutual aid Association in seoul. Subjects were 53 unexpected sudden death in school from elementary, middle, and high school students, and we explored the gender, month, a day of the week, year, contents of situation, and medical certificate of death. Statistic analysis were chi-square test, Cochran-Armitage trend test, and the tool was SAS 9.1.Results : There were 53 unexpected sudden death students(male 42 and female 11). The incidence of male students was higher than that of female during 16 years except in 1995. The incidence occurred in middle school students were 31 (58.5%) of 53 and were also most frequent in middle school students in both of male and female students. In 1990, the incidence was 8(15.1%) students, 6(11.3%) in 1992 , and 5(9,4%) in 2000 respectively. The frequency of unsuspected sudden death in March was 11(20.8%) of 53 students, 11 (20.8%) in September, 7(13.2%) in October. In Thursday, it was 12(22.6%) of 53 students. Only 14(26.4%) students of 53 died during general life, but 39(73.6%) were related to excercise. The diagnosis of 14 students died during general life were cardiac arrest 7(50.5%), brain disorder 3(21.4%) which were based on medical certificate. But the diagnosis of 39 students died during or after excercise were brain disorder including cerebral hemorrhage 9(23.1%), heart disease 9(23.1%), cardiac arrest 8(20.5%), and unknown 6(15.4%), respectively. Conclusion : The incidence of unexpected sudden death were more frequent in male students, in middle school, and in excercise-related situation and the trend was similar for 17 years. Therefore, to prevent the unexpected sudden death, it needs to further study substantially the risk factors of unexpected sudden death including past history, life-style, nutrition and development, family history, and learning environment.

  • Advances in research and medical and supportive care have contributed to a growing population of adults formerly treated for childhood cancer. History of cancer and its therapy can have significant life-long health implications. Late effects of cancer therapy can be insidious on onset, occur outside the pediatric age, and contribute to premature morbidity and mortality. In this review, I have focused on the key long-term effects of pediatric cancer therapy, particularly on the metabolic syndrome, including cardiopulmonary complications, infertility, and secondary neoplasm.

  • We investigated developmental stages of embryo and early life history of the Korean indigenous fish, the northern loach, Cobitis pacifica in 2009 in order to understand fundamental knowledges for conservation of this species. Eggs were obtained after hormones injections (LHRH-a, HCG) and were artificially fertilized by the dry method. The embryo was spherical, separative demersal, faint white, and averaged $1.09{\pm}0.04\;mm$ (n=20) in diameter. The hatching of the embryo took place in about 48 hours after fertilization under water temperature of $21.0{\sim}24.0^{\circ}C$ and the newly hatched larvae averaged $2.87{\pm}0.05\;mm$ (n=20) in total length (TL). Four days after hatching, the larvae grew up to $6.86{\pm}0.10\;mm$ (n=10) in TL and york sac absorption, mouth and anus opening were shown. Fourteen days after hatching, most of fin-rays appeared at $10.71{\pm}0.34\;mm$ (n=10) in TL and color spots on the body surface were attained. Twenty six days after hatching, the larvae grew up to $14.88{\pm}0.45\;mm$ (n=10) in TL, and all their fin-rays were formed. Therefore, according to current study regarding the morphological development of Cobitis pacidica, the conversion from larval to juvenile stages occurred at 26 days after hatching. Eighty days after hatching, the larvae were $33.3{\pm}1.25\;mm$ (n=10), and their body shape and color pattern were similar to adult fish. In this study, embryonic development and early life history of the northern loach, Cobitis pacifica show morphological characteristics of Cobitidae family. We expected that our results can be used as an fundamental knowledges for restoration study of indigenous fish species.

  • Olive flounder (Paralichthys olivaceus) is the major species developed for aquaculture in South Korea. Over the long history of olive flounder aquaculture, complex and diverse diseases have been a major problem, negatively impacting industrial production. Vibriosis is a prolific disease which continuously damages olive flounder aquaculture. A bacterial disease survey was performed from January to June 2017 on 20 olive flounder farms on Jeju Island. A total of 1710 fish were sampled, and bacteria from the external and internal organs of 560 fish were collected. Bacterial strains were identified using 16 s rRNA sequencing. Twenty-seven species and 184 strains of Vibrio were isolated during this survey, and phylogenetic analysis was performed. Bacterial isolates were investigated for the distribution of pathogenic and non-pathogenic species, as well as bacterial presence in tested organs was characterized. V. gigantis and V. scophthalmi were the dominant non-pathogenic and pathogenic strains isolated during this survey, respectively. This study provides data on specific Vibrio spp. isolated from cultured olive flounder in an effort to provide direction for future research and inform aquaculture management practices.

  • About 25 years ago, halfway along the recorded history of the neutron as a separate entity, Korea entered the nuclear age and initiated its own neutron research and development programs. Since that time Korean scientists have taken all possible advantages of the special opportunities offered by the neutron. Scientists the world over, in the Far East, hear East, and the West, have adapted these opportunities to their special needs. These needs are manifested in all phases of modern life, including power generation by nuclear means, food preservation, production of new types of food-bearing plants, commercial uses of activation analysis, irradiations, and isotope production, nuclear medicine, industrial quality control through nuclear measurements, and direct use of neutrons in research in many areas including solid state physics, chemistry, physics, biology, and medicine. Research with neutrons has been successfully conducted using nuclear research reactors of all sizes ranging from the very small (∼10 kilowatts) to the very large(50-100 Megawatts). This speaker has teen associated with nuclear research since 1945 and directly with neutron research since 1957. From this continuous research and development activity, he will report on some of the prospects in the second 50 years of the neutron.
