Gastritis cystica profunda (GCP) is a rare disease characterized by gastric foveolae elongation along with hyperplasia and cystic dilatation of the gastric glands extending into the tissue beneath the submucosa. GCP mainly develops at the gastroenterostomy stoma but can arise in a stomach that has not undergone surgery. The proposed pathogenesis is related to chronic inflammation, ischemia and the presence of a foreign body. GCP may present as a submucosal tumor, Polyp or a giant gastric mucosal fold. Endoscopic ultrasonography (EUS) is an effective diagnostic method for differentiating GCP from protruding and elevated gastric lesions. We report a case of GCP along with the endoscopic and EUS findings that were indistinguishable from a malignant submucosal tumor.

Background : To assess the current level of development of emergency medicine (EM) systems in Asia. Method : Survey of EM professionals from 12 Asian countries during a 90-day period from August to November 1998. 12 EM professionals from 12 Asian countries completed the survey. All participants were physicians. 7 participants (58%) gave presentations at an international EM conference during the study period. Respondents completed a 103 question questionnaire about the status of EM specialty, academic, patient care, information and management systems and the factors influencing the future of EM in their countries. Results : 92% of respondents stated that their countries have hospital-based emergency departments (ED). More than 80% of respondents reported that their countries have EMS systems and ED systems for trauma care and patient transfer. More than 70% stated that their countries have national EM organizations, EM research, national EMS activation phone numbers, ED systems for pediatric emergency care, emergency physician (EP) training in ACLS and ATLS and peer review. More than 60% reported official recognition of EM as an independent specialty status, ED triage systems and systems for customer service. More than 50% reported EM residency training programs, EM journals and EP ability to perform rapid sequence intubation (RSI). 50% reported EP ability to perform thrombolysis for acute MI and 33% reported EP ultrasonography. 92% felt that a lack of funding posed a moderate or great obstacle to the future development of EM in their countries. Conclusions : Many essential systems of EM now exist throughout Asia. In the systems of administration and emergency medical information in many countries, there are some parts to be developed further.

조상과 후손의 만남에 대한 동서양 다원적 패러다임 연구 -주자의 감응이론과 칼융의 동시성이론을 중심으로-

우리 주위에서 인과관계를 알지 못하는 현상들을 드물지 않게 접한다. 이러한 현상들은 사실이 아니라고 보기보다는 어떠한 중요한 사실을 아직 알지 못하였기 때문에 이해가 안 되는 것이 아닌지 반문하게 한다. 이 글에서 근거로 삼은 자료는 논문의 공동필자인 박재갑 교수 집안에서 일어난 두 가지 사건이다. 첫째는 박재갑 교수의 15대 조상으로 1545년에 돌아가신 필재 박광우의 시신을 이장하는 날 밤, 사촌 형인 박재학의 꿈에 필재 할아버지가 나타나 자신이 소장하였던 방울을 찾아오라는 말을 듣고, 이후 파주에 가서 방울을 소장하고 있던 사람에게 방울을 찾아온 사건이다. 둘째는 박재갑 교수의 부친이 돌아가신 날 이모의 출가한 딸 꿈에 박재갑 교수의 부친이 금시계를 가지고 나타나신 꿈을 꾸었다. 이모의 딸은 이모부가 돌아가신 줄도 모르고 있었고 더욱이 이모부의 아들 부부가 금시계를 사갖고 온 것을 알 수가 없었는데, 금시계와 관련된 꿈을 꾼 일련의 사건이다. 과학을 주류 패러다임으로 삼고 있는 현대문명에서 보면, 신비롭고 기이한 현상은 그저우리가 확인하지 못하는 일상이나 정신현상의 일부일 수도 있다. 그런데 주자(朱熹,1130~1200)의 감응이론과 칼 구스타프 융(Carl Gustav Jung, 1875~1961)의 동시성이론은 인과관계를 알 수 없는 현상들에 대해 각기 다른 해석을 내놓는다. 인과관계를 알 수 없는 현상은 제한적 합리성의 완고한 세계관 자체가 균열되는 사건이며, 동시에 우리의 삶이 이해의 영역을 넘어선 광대한 현실에서 펼쳐지는 사건임을 말해준다. 실로 미지의 우주, 그리고 삶과 죽음에 대한 다원적 패러다임의 폭넓은 수용과 진지한 대화가 더 요청되는 시대이다. 이러한 관점에서 본 연구에서는 조상과 후손의 만남, 감응, 현현의 사례를 성리학의 감응이론과 칼 구스타프 융의 동시성이론의 관점에서 조명하고자 한다. We frequently witness phenomena which occur around us, not revealing the causal relationship. We can ask ourselves whether such phenomena are hard to understand not because they are not true facts but because they are beyond our understanding. The reference data for such a phenomenon in this article are the two events that had occurred in the family of Professor Jae-Gahb Park, one of the co-authors of this article. Firstly, on the eve of the night when his fifteenth-generation ancestor’s grave was to be moved, his ancestor appeared in his consin’s dream, telling him to go and find the bell that his ancestor had cherished. Accordingly, his father and relatives went to Paju county, where his ancestor’s grave is located, to remove the grave to another place. In the process, his father told the participants what his consin had dreamt of including a grave keeper who had kept the bell after reburial. The grave keeper returned it to his father after hearing from him. Secondly, On the day when Professor Park’s father died, his father appeared in the dream of his maternal aunt’s married daughter, carrying a gold watch with him. She was not aware that Professor Park’s father was dead. Furthermore, Neither did she know that Professor Park‘s old brother and his wife in America had bought the gold watch for his father. These two cases are representative examples of ancestors’ revelation through dream. According to the modern civilization which regards sciences as its mainstream paradigm, such mystical and arcane phenomena are just a part of mental phenomena that we cannot verify with our knowledge. However, there are two scholars presenting different explanations about the phenomena of which the causal relationship is not understood yet: Carl Gustav Jung (1875~1961)’s phenomenon of synchronicity and Zhu Xi (朱熹, 1130~1200)’s theory of correlation. A phenomenon whose causal relationship is not understood yet is an event in which the obstinate outlook of the restrictive rationality breaks off, and at the same time our life spreads into the vast realm transcending our understanding. We are living in an era when more discussions on the unknown universe and pluralistic paradigms on the questions about life and death need to be made. In this regard, Gustav Jung’s concept of Synchronicity and Neo-Confucian theory of correlation is instrumental in overcoming the phenomenon and case in which the causality breaks off.

Renal papillary necrosis occurs most commonly in association with urinary tract infection, diabetes mellitus, sickle cell disease, vascular disease, and analgesic nephropathy. Clinical presentation may be related to symptoms of pyelonephritis such as flank pain, renal colic, hematuria, Proteinuria, recurrent fever. The necrotic tissue may be sloughed off, and the diagnosis can sometimes be made by finding piece of renal medullary tissue in the urine. Pyelography may demonstrate cavities and sinuses in the resion of papillae. Anuria & oliguria can lead to the acute renal failure, and especially prognosis and progress may be affect influenced by urinary infection. We report a case of renal papillary necrosis with ingestion of bear gallbladder. On pyelography, Persistent contrast is diagnostic clue of renal papillary necrosis. This case is not be related to urinary tract infection, but occurred acute renal failure. Expectant treatment was gone.

To simulate accurate spectral reflectance from the red-green-blue output of a video digitizing system, a set of basis functions were computed. 1565 reflectance spectra of the chips in the Munsell Book of Color(Glossy) were measured with a spectrophotometer in KRISS. The autocorrelation matrix of these samples was formed and the eigenvectors and the eigenvalues of this matrix were computed by using Karhunen-Loeve transformation.

Transthyretin의 Glutathione 자동산화 촉진작용

박종근,정신,김재휴,김수한,강삼석,이제혁,안봉환 대한신경외과학회 1994 Journal of Korean neurosurgical society Vol.23 No.8

When reduced glutathione(GSH) was incubated at neutral pH and at 37°, its concentration decreased slowly with formation of oxidized glutathione(GSSG). Autooxidation of GSH was accelerated by Cu^(2+) and Hg^(2+), but not by other common mono-, di-, and tri-valent cations. Transthyretin was found to stimulate autooxidation of GSH in the presence or absence of Cu^(2+) and Hg^(2+). EDTA inhibited perfectly the autooxidation of GSH regardless of the presence of transthyretin. The stimulating activity of transthyretin was maximal at pH 7.0, declining progressively with increase or decrease of pH from 7.0. Sulfhydryl-blocking agents such as p-hydroxymercuribenzoic acid and Nethylmaleimide markedly inhibited the stimulating activity of transthyretin. Transthyretin stimulated autooxidation of other sulfhydryl compounds such as clithiothreitol and cysteine. However, it did not show a significant effect on autooxidation of sulfhydryl group of egg albumin and eye lens proteins. And transthyretin did not cause any oxidative change to thyroxine(T₄), 3, 5, 3Ltri iodo thyronine(T₃) and 3, 3: 5~triiodothpnine(rT₃) bound to it in the presence of GSH and Cu^(2+). The above results suggest that transthyretin may play a role in regulation of oxidized status of sulfhydryl groups in blood plasma and cerebrospinal fluid

Hydrogen embrittlement (HE) mitigation on the low alloy steel was studied using electrochemical technique. This method can be applied to reduce HE susceptibility. Hydrogen induced cracking (HIC) characteristics of the low alloy steel was investigated in aerated and deaerated borate buffer solution (0.3M H₃BO₃ + 0.074M N₂B_(4)O_(7), pH 8.4). The electrochemical properties of the low alloy steel showed passive behavior in this environment. By performing galvanostatic and potentiostatic test, hydrogen was charged and discharged to specimens respectively. By applying the potential of +630 mV_(SCE), the accumulated hydrogen was eliminated electrochemically. A specimen discharged for 24h indicated the efficiency of the hydrogen discharge up to 99.9%. Slow strain rate tests (SSRT) results showed that a specimen with higher hydrogen concentration revealed inferior mechanical properties such as shorter time to fracture, lower elongation, ultimate tensile strength and yield strength values. Furthermore, SEM fractographs revealed that the higher the hydrogen concentration is, the more probable the features of brittle fracture are. (Received July 26, 2004)

This study was conducted to provide basic data for the development of natural seasoning. The quality characteristics of water extracts from Pleurotus ostreatus and Lentinus edodes were determined. Also, savory taste, fragrance, color and overall preference was evaluated. The preference test on the seasonings prepared from Pleurotus ostreatus and Lentinus edodes with the addition of sea tangle was also performed. The crude protein content of dried, Lentinus edodes and Pleurotus ostreatus was 20.4% and 30.4% respectively. The total organic acid contents were higher in Pleurotus ostreatus than in Lentinus edodes extracts. The total free amino acid and total nucleotide contents were higher in Pleurotus ostreatus than in Lentinus edodes extracts. Three nucleotide, adenosine monophosphate(AMP), guanosine monophosphate (GMP), xanthine monophosphate(XMP) were found in mushroom seasonings while inosine monophosphate (IMP) was not detected. Pleurotus ostreatus extract showed higher score in savory taste and overall acceptability than Lentinus edodes extract, Pleurotus ostreatus seasoning added with 196 sea tangle and Lentinus edodes seasoning added with 1.5% sea tangle were rated as high in overall quality. In a sensory test of foods cooked with mushroom seasoning. It was shown that panels in their twenties well used to the taste of monosodium glutamate while the people in their thirties preferred the specific flavor of the mushroom seasoning.
