목 적:단무지 공장에서 질식사고를 일으켰던 가스의 종류를 알아내고, 이러한 가스중독의 방서선학적 소견을 소개하기 위하여 본 연구를 하였다. 대상 및 방법:단무지 공장에서 발생한 질식 사고자 3예중 생존자 1예를 대상으로 단순흥부X-선검사와 CT 소견을 분석하였으며, 가스의 종류를 알아내기 위하여 단무지를 유리병에 넣어 발생된 가스를 가스크로마토그래픽을 이용하여 분석하였다. 결 과:단무지 공장에서 발생한 질식사고자중 생존한 1명의 방사선학적 검사에서 신속히 호전되는 폐경결(consolidation)을 볼 수 있었으며 이는 폐부종의 소견임을 알 수 있었다. 협기성 상태에서 단무지를 담은 유리병의 상층부 가스를 실험 분석한 결과 이산화탄소, 에칠알코올이 다량으로 검출되었으나 독성가스는 주로 황화수소이였다. 결 론:단무지 공장의 질식 사고자에서 폐방사선학적 소견은 폐경결을 보이는 폐부증으로서 이는 실험을 통해 단무지에서 발생되는 유독가스인 황화수소 때문임을 입증하였다. Purpose: To identify the main toxic gas released from salted radish in rice bran(Dan-M-Ji) and to introduce the radiological findings of the patient who was exposed to the gas. Materials and Methods: Chest radiographs and CT scans of one survivor among three men who were exposed to the gas from Dan-Mu-Ji were reviewed. Gas obtained from the closed bottle containing Dan-Mu-Ji was analized by using the gas chromatography. Results: The radiographlc examinations of the survivor were suggestive of pulmonary edema with it's rapidly improving consolidations in both lung. The headapace gas within the bottle containing Dan-Mu-Ji was mainly composed with carbon dioxide, ethyl alcohol and hydrogen sulfide, of which hydrogen sulfide was considered the main toxic gas released. Conclusion: Under the anaerobic condition, Dan-Mu-Ji released toxic hydrogen sulfide. Inhalation of hydrogen sulfide might produce non-cardiogenic pulmonary edema.

This paper is intended to propose future alteration directions and contents of laws and regulations related to housing supply system and Building Code on the assumption that the tendency to extend the dwelling area to the balcony space in apartment units was derived from joint and composite demand of the criteria of floor area in Building Code and the residents' requirement for storage space enlargement. For this purpose, this paper has deeply reviewed the causes and transitions of change trend that the balcony has been transformed outer space into inner space for private use only by customary housing design. And finally the 5-conclusion is proposed; Firstly, the balcony spaces in apartments has to be treated as outdoor space according to the essential meaning and interpretation on balcony itself on Building Code. Secondly, balcony space so called as service space has to be included into housing supply area, and thirdly, the permitted depth and width of balcony would be adjusted. Fourthly, the concealed spaces for unit area computation also have to be include into common area for dwelling or the other common area. And finally the system of taxation and laws and guidelines for sale and real-estate registration of property has to be adjusted together with the laws and regulations related to housing supply system and Building Code.
