용종성 낭종성 위염(GCP)은 드문 질환으로 흔히 위 점막과 점막하층에서 다발성 낭성 종물로 나타난다. 주로 과거에 위절제술을 시행받은 사람에서 발병되며 드물게 수술병력 없이 위에서 발병되기도 한다. 육안적으로 점막하 종양, 유경성 또는 무경성 용종, 거대 점막 주름 등 다양한 형태로 나타난다. 최근 저자들은 위절제술의 과거력이 없는 환자에게서 우연히 실시한 상부위장관 내시경 생검결과 과형성 용종을 진단하여 내시경적 점막절제술을 통해 용종성 낭종성 위염으로 확진하여 치료한 증례를 경험하였다. 따라서 위용종 생검에서 과형성 용종으로 진단되더라도 용종성 낭종성 위염의 가능성을 염두에 두어야 하겠다. Gastritis cystica polyposa (GCP) is a rare lesion characterized by hyperplastic and cystic dilatation of the gastric mucosal glands infiltrating into the underlying submucosa. In most cases, it develops in patients who have undergone a gastroenterectomy, but can occasionally be found in an unoperated stomach. GCP may present as a submucosal tumor or polyp, and rarely as a giant gastric mucosal fold. We experienced a case of GCP that presented as a hyperplastic polyp, and it was unrelated to any gastric surgery. Upper endoscopy revealed the presence of a subpedunculated polyp in the posterior wall of the antrum. The lesion was successfully removed by endoscopic mucosal resection and diagnosed as a GCP.

Acute colonic ischemia is the most common form of gastrointestinal ischemia. The majority of cases of non-occlusive ischemic colitis are associated with severe congestive heart failure with low cardiac output, or disease states resulting in dehydration, or the splanchnic vasoconstrictive effect of some medications. Reactive splanchnic vasoconstriction is responsible for nonocclusive ischemic colitis. The authors report a case of 37-year-old man, who had a history of 8-year gout and no evidence of heart disease or severe dehydration and developed segmental ischemic colitis during nonsteroidal antiinflammatory drug treatment, which ultimitely progressed to transmural infarction, therby undergone extended right hemicolectomy.

Churg-Strauss syndrome (CSS) or allergic angiitis and granulomatosis is a disorder characterized by pulmonary and systemic small-vessel vasculitis, extravascular granulomas, and hypereosinophilia. It occurs in individuals with asthma and allergic rhinitis. The diagnosis of CSS is made on the basis of clinical and pathologic features. According to 1990 American College of Rheumatology(ACR) criteria for the classification of CSS, 6 criteria were developed. The presence of 4 or more of these criteria yielded a sensitivity of 85% and a specificity of 99.7%. We describe a case of CSS in a 62-year-old female who met all of 1990 ACR criteria, but presented as like a as rheumatoid arthritis initially. Clinical symptoms, laboratory and roentgenographic findings gradually responded to high dose prednisolone treatment and resolved 3 weeks later. After discharge, she has been treated with oral prednisolone in a tapering course. Although polyarthritis with eosinophilia, vasculitis, and neuropathy are clinical manifestations of rheumatoid arthritis, those maniestations frequently occur during the vasculitic phase of the CSS. This case suggests that thorough differentiation of extra-articular manifestations of RA from clinical manifestations of CSS is considered when we meet a patient who have polyarthritis and vasculitis.

This study investigated the relationships between secondary inorganic aerosols in PM<SUB>2.5</SUB> and precursor gases emitted from active agricultural areas over a period of one year, from June 1, 2022, to May 31, 2023, in Rice (Buan) and Fields (Gochang) in the Jeollabukdo Region simultaneously. In addition, the study examined the particle-phase conversion rates of gaseous precursor compounds to elucidate factors influencing the chemical characteristics of PM<SUB>2.5</SUB>. The high NH₃ concentration in the early morning, assuming constant soil emission, suggested a significant influence from surrounding environmental conditions. In Buan and Gochang, NO₃<SUP>-</SUP> predominantly existed in particle form during cold winter temperatures, while in hot summer temperatures, it mainly existed in the gas phase, demonstrating distinct seasonal behavior. Furthermore, NO₃<SUP>-</SUP> was influenced by localized generation due to regional primary emissions. The study results indicate that the formation of NO₃<SUP>-</SUP> in Buan and Gochang is primarily governed by NH₄<SUP>+</SUP> originating from regional soil-emitted NH₃. These findings can serve as crucial foundational data for elucidating the seasonal concentrations of precursor gases, including NH₃, emitted to agricultural regions.

The purpose of this study is as follows; First, this study developed the instruments of measurement to measure the quality of HAS(information quality, system quality, and service quality). Second, this study investigated statistically perception differences of the quality by t-test between hotel employees in Jeju and those in Seoul. The hypotheses were developed from reviewing the former literatures and tested empirically. The Questionnaires were collected from 214 middle or higher managers at deluxe hotels located in Seoul and Jeju during February 13 to March 10,2004. This study was conducted using frequency analysis, descriptive analysis, and t-test by statistical packages of SPSS SPSSWIN version 10.0. The results of this study showed that hotel employees in Jeju perceived positively the quality of HAS than those in Seoul.

In spite of nationmide tuberculosis control program, tuberculosis is still prevalent in Korea. Accordingly, tuberculous meningitis also poses one of the main trouble some problems. Recently, We experienced a perplexing case of tuberculous menin-gitis and tubercdoma in a 24-year old female patient. She was admitted to our hospital owing to meningeal irritation sign, aphasia, VI nerve palsy, and ,fever. CSF analysis showed a finding consistent with that of presumptive tuberculous meningitis.. Initial MRI of the brain revealed a large mass(tuhercu1oma) on left parieto-temporal area. Antitubeculous regimen(1soniazid (INH), rifampin(RMP), ethambutol(EMB), pyrazinamide(PZA)} of meningeal dose was given immediately, and her symptoms and signs were dramatically disappeared with a few days after treatment. She was discharged with improved condition and under maintenance treatment of tuberculosis. Follow-up one year after treatment. revealed that the previous lesion was nearly diminished. She showed no symptom at all until she recognized a total blindness of sudden onset on her left eye a t the 18th month of treatment. Brain MRI checked at that time showed multiple masses of tuberculoma scattered over the brain base and one of them invaded left optic nerve. In our opinion, the cause of relapse in this patient might he explained by the selection and ultimate replication of a minor population of resistant strain. Although such relapse is an extremely rare event, we think that we should always pay attention to this possible resistance problem every time we meet patients with tuberculous meningitis.
