국내에서 데이터통신 서비스가 개시된지 수년 사이에 데이터통신에 관한 이해의 폭과 그 수요의 확대가 괄목할만한 변화를 보이고 있다. 새로운 서비스와 발전된 형태의 기술에 대한 욕구도 크게 늘고 있는 형편이다. 데이터통신의 한 단계 도양을 위한 개선책을 서비스와 제도, 그리고 기술의 측면에서 찾아본다.

Background: Toluene diisocyanate (TDI) is known to be the most common cause of occupational asthma (OA) in Korea. Although TDI can elicit humoral immune responses including specific-IgE (sIgE) and specific-IgG (sIgG) responses, the exact role of these immune responses has not been clearly clarified yet. Objective: This study was carried out to estimate the prevalence of TDI-induced OA, and to evaluate the clinical significance of TDI-related humoral immune responses in currently TDI-exposed workers. Method: Questionnaire interview for respiratory symptoms was conducted to 170 workers with direct exposure to TDI (exposed group). After screening survey, workers with suspected occupational asthma were selected for methacholine and TDI bronchial provocation tests (BPTs). Serum sIgG and sIgE antibodies to TDI-HSA conjugate, and sIgG to cytokeratin (CK) 8, 18, and 19 were detected by enzyme-linked immunosorbent assay in 170 exposed workers, and compared with 61 unexposed workers in the same workplace (unexposed group) and 75 unexposed healthy controls(healthy control group). Result: Eleven (6.9%) among 170 workers complained symptoms of OA, and 7 of 11 symptomatic workers showed positive airway hyperresponsiveness to methacholine (4.1%). One worker with spray-painting job was confirmed as having TDI-induced asthma by showing positive responses to both methacholine and TDI BPTs. The prevalence of sIgG to TDI-HSA conjugate was significantly higher in TDI-exposed workers (10.1%) than in unexposed workers (0%) and healthy control (2.7%). However, no significant difference was noted between symptomatic (18.2%) and asymptomatic workers (9.5%) among the exposed group. The prevalences of sIgE to TDI-HSA conjugate and sIgG to CK 8, 18, 19 were not significantly different between the three groups. Conclusion: The prevalence of TDI-induced OA was noted to 0.58% in the current working environments. The clinical significance of TDI-induced humoral immune responses may be clarified by further prospective studies. (Korean J Asthma Allergy Clin Immunol 2005;25:276-283)
