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.

본 논문은 제어이론을 전기-유압 서어보시스템에 적용시켜 그 응답특성을 구한 것이다. 먼저 시스템의 전달함수를 구하였으며 이 전달함수를 이용하여 유량게인의 변화가 시스템의 응답특성에 미치는 영향을 아날로그식과 디지탈식으로 시물레이션하였다. 그결과 유량게인이 증가하면 시스템의 응답성은 개선되나 과도응답의 오버슈트가 커졌다. 또한 미분보상요소를 시스템의 전달함수에 삽입하여 아날로스식과 디지탈식으로 시뮬레이션한 결과 미보상시보다 시스템의 응답성이 개선되어 짐을 확인하였다. The aim of this study is to apply control theory to the electro-hydraulic servosystem. First the transfer function of the system is derived, and the system is simulated by analog and digital method with the variations of flow gain. With increasing in flow gain, the response of the system is improved, but the overshoot of transient response is increasing. The system response is improved by inserting a compensator element to the transfer function of the system.

As accounting is an outgrowth of society, we can say that the accounting system of each country is derived from its economic situation and from the people's outlook no economic values. Thus when the economic situation of one country is different from that of another country, and the outlook of the people of one country is different from that of another country, they the accounting system for changing prices as well as general accounting systems may be different. Actually accounting systems of different countries are not identical. The writers of this paper try to find an accounting system for changing prices suitable to out country. The writers review various theories on accounting systems for changing prices, survey accounting systems of various countries and basic patterns of such systems, and in vestigate the actual conditions of our country in order to provide accounting information which reflects the effect of changing prices and to give a practicable accounting system. In this paper, the writers state their opinions about accounting systems for changing prices as follows: 1)The demand for the publication of accounting information about the effect of changing prices upon the financial status and operational result of a business is a world-wide trend. Considering that our industries are now aiming at opening a capital market, we should establich an accounting system for changing prices in order to follow the world-wide current. 2) As we intend to follow the world-wide current, to get useful accounting information, and to get a practicable accounting system, the most suitable system for us is the current value accounting system The current value accounting system mentioned here does not provide information supplementary to that of the financial statements based on the historical cost but it provides a substitute of the current value financial statements for those based on the historical cost. Financial statements based on current values are standard statements. 3) In our country, there are no active studies or discussions on the accounting systems for changing prices. We need to set up an organization entirely responsible for the establishment of a desirable accounting system for changing prices, responsible for the establishment of guidelines for putting the system to use, and responsible for the coordination of the interests of those concerned.

박정주,이만홍,신동범 大韓神經精神醫學會 1985 신경정신의학 Vol.24 No.3

The importance of milieu characteristics of psy-chiatric inpatient treatment programs has been widely recognized and a number of instruments hare been developed to measure these milieu char-acteristics. Amog these instruments, the Ward Atmosphere Scale (WAS), which was developed by Dr. Moos and his colleagues in the Social Ecology Laboratory at the Stanford University, is one of the most widely used and the most reliable test. In previous study of this series by the authers, the WAS proved to be applicable with the subs-tantial reliability in Korea and useful in system-atic comparisons among the different therapeutic milieus of Korea and possibly between the char-acteristics of American and Korean Programs. So for the next step, the authers administered the WAS to 291 subjects sampled from 3 different psychiatric inpatient wards: Custodial ward(CUW), Medically oriented ward (MOW) and the authers’ Therapeutic community ward(TCW) to assess the characteristics of social atmospheres of several different therapeutic milieus. The authers com-pared these 3 different psychiatric wards: CUW, MOW and TCW and compared the subgroups according to subject’s status in each therapeutic milieu: staff, student and patient and finally compared a Korean TCW to American Normative Sample. The results were as follows: 1. The subscale means of WAS were highest in TCW, and MOW, CUW in order. 2. According to the characteristics of Dimension of WAS, TCW was analogous to Therapeutic community program, MOW to Relationship-oriented program and CUW to Control-oriented program of Price and Moos. 3. Patients perceived their therapeutic milieus as more restricted by staffs and more difficult to express anger and aggression openly than staffs perceived in all three psychiatric wards. And staffs saw their therapeutic milieus more positively and optimistically in TCW and more negatively and pessimistically in CUW. 4. The subscale means of WAS were higher in a Korean TCW than American Normative Sample but anger and aggression was lower in a Korean TCW than American Normative Sample significantly.

Structural health monitoring system should developed to be based on internet and database technology in order to manage efficiently large structures. This system is operated by internet connected with the side of structures. The monitoring system has some functions: self monitoring, self diagnosis, and self control etc. Self monitoring is the function of sensor fault detection. If some sensors are not normally worked, then this system can detect the fault sensors. Also Self diagnosis function repair the abnormal condition of sensors. And self control is the repair function of the monitoring system. Especially, the monitoring system can identify the replacement of sensors. For further study, the real application test will be performed to check some unconvinrences.

As a part of Kangwha Mental Health project, a psychiatric epidemiologic survery was conducted in 1985 using the Korean version of NIMH-Diagnostic Interview Schedule III A. The authors reanalyzed the data so that the prevalence rates of depression and somatization disorder and frequencies of depression and somatization symptoms were compared among alcohol dependence, alcohol abuse and non-alcoholic males. The results were as follows; 1) Although there were no significant differences in the prevalence rates of major depression dysthymic disorder, and somatization disorder among male alcohol abuse, alcohol dependence and non-alcoholic group, the prevalence rates were slightly higher in both alcohol use disorder groups compared to non-alcoholic group. 2) Frequencies of depression symptoms such as depressive mood more than 2 weeks, insomnia and slowed thinking were significantly higher in both alcohol abuse and alcohol dependence group compared to non-alcoholic group, but frequencies of symptoms such as depressive mood more than 2 years, recurrent thoughts of death, wishes to be dead, suicidal ideation and suicidal attempt were significantly higher in alcohol dependence group compared to both alcohol abuse and non-alcoholic group. 3) In alcohol dependence group, the frequencies of somatization symptoms such as vomiting spells, blurred vision, deafness, trouble walking, paralysis or musle veakness, palpitation, weakness difficulty swallwing and inability to work were significantly higher compared to non-alcoholic group, and frequencies of symptoms such as abdominal pain, loss of voice and anesthesia on extrimities were significantly higher compared to non-alcoholic group as well as alcohol abuse group. 4) Mean score of somatization symptoms were significantly higher in alcohol dependence group compared to alcohol abuse and non-alcoholic group, but that of depression symptoms were significantly higher in both alcohol abuse and alcohol dependence groups compared to non-alcoholic group.
