Hemoptysis is a major reason for emergency department (ED) visits. Catamenial hemoptysis (CH), a rare condition of thoracic endometriosis, can cause recurrent hemoptysis but is difficult to diagnose in the ED due to the scarcity of cases and nonspecific clinical findings. We report a case of a 26-year-old woman who presented to the ED with recurrent hemoptysis since 2 years without a definite cause. Her vital signs and blood test findings were unremarkable. Chest computed tomography (CT) did not show any specific lesions other than a non-specific ground-glass opacity pattern in her right lung. She was on day 4 of her menstrual cycle and her hemoptysis frequently occurred during menstruation. Although there was no histological confirmation, based on her history of hemoptysis during menstruation and no other cause of the hemoptysis, the patient was tentatively diagnosed with CH and was administered gonadotropin-releasing hormone. She had no recurrence of hemoptysis for 3 months. While CH is difficult to diagnose in the ED, the patient's recurrent hemoptysis related to menstruation was a clue to the presence of CH. Therefore, physicians should determine the relationship between hemoptysis and menstruation for women of childbearing age presenting with repeated hemoptysis without a definite cause.

The conventional computerized numerical controller (CNC) of machine tools has been increasingly replaced by a PC-based open architecture CNC (OAC) which is independent of the CNC vendor. The OAC and machine tools with OAC led the convenient environment where it is possible to implement user-defined application programs efficiently within CNC. Tis paper proposes a method of operational fault cause diagnosis which is based on the status of programmable logic controller (PLC) in machine tools with OAC. The operational fault is defined as a disability state occurring during normal operation of machine tools. The faults are occupied by over 70% of all faults and are also unpredictable as most of them occur without any warning. Two diagnosis models, the switching function (SF) and the step switching function (SSF), are propose in order to diagnose the fault cause quickly and exactly. The cause of an occurring fault is logically diagnosed through a fault diagnosis system (FDS) using the diagnosis models. A suitable interface environment between CNC and develope application modules is constructed in order to implement the diagnostic functions in the CNC domain. The diagnosed results were displayed on a CNC monitor for machine operators and provided to a remote site through a web browser. The result of his research could be a model of the fault cause diagnosis and the remote monitoring for machine tools with OAC.

공익연계마케팅은 소비자들이 조직이나 개인의 목적을 만족시키려는 기업과의 이윤 창출적인 교환행위에 참여함에 있어, 기업이 지정된 사회적 명분을 대상으로 일정금액을 기부하는 것을 특징으로 하는 마케팅 활동이다. 본 연구는 공익연계 마케팅 메시지 제시여부가 소비자 제품태도에 미치는 영향력을 확인하고, 더불어 소비자의 윤리적 소비성향 및 사회신뢰성향 그리고 제품유형(실용재 vs. 쾌락재)의 조절적 역할을 규명함으로써 실무적인 시사점을 제시하고자 하였다. 연구결과, 소비자들은 공익연계 마케팅 메시지가 제시되지 않은 제품보다 공익연계 마케팅 메시지가 제시된 제품에 대하여 더 호의적인 태도를 보이는 것으로 나타났다. 또한 소비자의 윤리적 소비성향과 사회적 신뢰성향이 높을 경우 공익연계 마케팅 메시지가 더 강한 영향을 미치는 것으로 나타났다. 하지만 제품유형에 대한 조절효과는 유의하지 않은 것으로 나타났다. 이들 결과는 기업이 공익연계 마케팅 활동을 전개하는 것도 중요하지만, 그에 앞서 소비자들의 윤리적 소비성향과 사회적 신뢰성향을 높여줄 수 있는 다양한 캠페인 등을 전개할 때, 이러한 마케팅 활동이 보다 큰 성과를 낼 수 있음을 시사하고 있다.

To find out the actual status of treatment of physically handicapped who were stayed of home, 320 physically handicapped persons were selected among total 6,264 physically handicapped registered in Taejon city, surveyed from January 1st to March 30, 1997. Following are the results ana lysed of collected data from 201 samped persons. 1. For the cause of physically handicapped, 36.3% was congenital, 26.9% was cerebralvascular acciednt(CVA). and 14.9% was infectious diseases and others in that orders. The must frequest cause of below 20 years age group was congenital cause, but that of $20{\sim}30$ years age group and $40{\sim}50$ years age group were accident and CVA repectively. 30.0% of respondents caused by infection and others earned household living expenses. Household living expenses were higher among the respondents caused by congenital cause but those were lowest in the accidental couse group. Handicap durations were longer in the accidental cause group and infections and others group than the congenital cause group and CVA group. 2. 54.7% of studied handicapped were under treatment. But 36.3% of them were stopped treatment, and 8.9 % of them answered not treated. Most handicapped, coused by congenital and CAV, were under treatment, but most of them caused by accidental and others were stopped treatment. 3. For the medical facilities, 54.5% of them utilized welfare facility, but 25.5% utilized general hospital and 20.0% of them utilized oriental medical hospital and health centers. Congenital cause group frequently selected welfare facility for the treatment facility. But accidental cause group frequently seleced general hospitals and CVA gruop frequently selected oriental medical hospital and others. The medical cost of welfare facility, oriental medical hospitals and others were lower than that of general hospitals. 4. The proportions of under treatment were higher among yonger age higher monthly living expenses group shorter handicapped duration groups, congenital cause group and handicap grade II group. But that of stop treatment were higher among congenital cause group, infectious and others cause group, and handicap grade I & then III group. 5. For the feelings satisfacion about medical treatment, only 35.3% of under treated group responed satisfation. 55.5% of them responded so-so, but 9.1 % responed dissatisfaction. The proportion of satisfaction was higher among shorter handicap duration group.

방사선이용 기관의 증가에 따라 방사선안전규제의 수요도 지속적으로 증가하고 있으므로 방사선안전규제의 합리화를 위한 객관적인 근거자료를 도출하기 위해서 방사선안전관리자를 통한 실질적인 일반화된 측정도구를 개발하고자 하였다. US NRC NUREG 1556(방사성물질에 대한 통합지침) Vol 1~21의 내용, 원자력안전법 등의 내용을 근거로 예비문항을 작성하여 국내 방사선이용 허가기관의 약 10%에 해당되는 방사선안전관리자를 대상으로 설문조사를 실시하였다. 그 결과, 요인분석 20개 문항에 대해 3개의 요인이 추출되었다. 요인1은 '방사선안전관리 규제요건', 요인2는 '실질적인 안전규제의 부합성', 요인3은 '방사선원 분류'관련으로 각각 명명하였다. 각 요인의 분산 설명력은 요인1이 40.140%, 요인2가 13.721%, 요인3이 6.556%로서 전체 60.417%의 설명력을 나타내었다. 본 연구에서 도출된 방사선안전규제 측정도구를 사용하여 방사선안전규제 기준을 도출한다면 국제기준에 적합할 뿐만 아니라 현장의 방사선안전관리자에게 실용성 있는 기준을 제시할 수 있을 것이라고 사료된다.

This study was conducted to evaluate the accuracy of the official death registry in rural area. The base data used for the study was 379 deaths registered during the period of 1993 and 1994 in 4 rural townships of Chonnam province. The interview survey for cause-of-death was performed on the next of kin and/or neighbor. Additional medical informations were collected from hospitals and medical insurance associations for the purpose of verification. The underlying cause-of-death of 278 cases presumed by the survey was compared to the cause on official death registry. There was a prominent disagreement of cause-of-death between the survey data and the registry data(agreement rate: $38.9\sim44.6%$, according to disease classification method). These results may be caused by extremely low rates of physicians' certification, which were mostly confined to the poisoning and injury. Symptoms, signs, and ill defined conditions on death registry could be classified into circulatory disease(32.3%), neoplasm(21.2%), digestive disease(7.1%), injury and poisoning(7.1%) and so on. These results suggest that careful attention and verification be required on utilization of death registry data in rural area.

어선에 의한 해양사고의 가장 큰 문제점은 경계소홀로 충돌, 접촉, 좌초, 전복, 및 침몰 등의 사고가 발행한다. 또한 사고가 발생하더라도 목격자가 없거나, 있다고 하더라도 사고 당시의 상황으로 인한 혼란으로 정확한 증거로써 활용되기 어려워 대부분의 사고 원인이 밝혀지는데 어려움이 많다. 사고가 발생한 후에 정확한 사고 규명을 위해서는 운항 기록을 기록하는 VDR(: Voyage Data Recorder) 시스템을 설치하여 하나 가격이 비싸고 어선에 적합하지 않아 잘 이용되지 않고 있다. 이에 본 논문에서는 어선에 적합한 운항 영상 보관을 위한 VDR 시스템을 설계 및 개발하였다. 이를 활용하는 경우, 어선에 의한 해양사고가 발생하더라도 신속하게 사고 규명이 가능하고, 사고 원인에 따른 적절한 조치를 취할 수 있기 때문에 해양사고 예방에도 많은 도움이 될 것으로 예상된다.

Staphylococcus aureus is an important cause of human infections, and it is also a commensal that colonizes the nose, axillae, vagina, throat, or skin surfaces. S. aureus has increasingly been recognized as a cause of severe invasive illness, and individuals colonized with this pathogen are subsequently at increased risk of its infections. S. aureus infection is a major cause of skin, soft tissue, respiratory, bone, joint, and endovascular disorders, and staphylococcal bacteremia may cause abscess, endocarditis, pneumonia, metastatic infection, foreign body infection, or sepsis. The authors describe a case of a fisherman who died of sepsis on a fishing boat during sailing out for fish. The autopsy shows paravertebral abscess, pus in the pericardial sac, infective endocarditis with vegetation on the aortic valve cusp, myocarditis, pneumonia and nephritis with bacterial colonization, and also liver cirrhosis and multiple gastric ulcerations.
