In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

The risk posed to human health by environmental manganese (Mn) exposure is unknown. The purpose of this study is to establish if subclinical effects related to Mn exposure and examine the factors influencing psychoneurobehaviral outcomes of Mn exposed workers. This study involved 121 male workers of welding, alloy furnace, and manufacturing of welding stick. Study investigations include: a questionnaire covering demographic characteristics, job and exposure history and medical symptoms and conditions, monitoring workplace air for personal exposure to respirable and inhalable manganese, analysis of blood and urine samples, psychoneurobehaviral test(neurobehaviral core test battery(NCTB), signal change on magnetic resonance imaging (MRI) scans, minimental state and neurological examination). The main results of this study were as follows; 1. Preliminary results showed that, with increasing manganese exposure, neurobehaviral performance was poorer and signal change on MRI scans increased. 2. The results of examination revealed significant relations on psychoneurobehaviral outcomes (neurobehaviral performance, signal change on MRI scans, and neurological features). 3. In multiple regression, age and educational status as demographic variables and exposure level were significantly related to neurobehaviral test. Also exposure level and serum Mn concentrations were positively related to signal change on MRI scans and neurological features affected by Mn on the brain (signal change). 4. Psychoneurobehaviral outcomes from Mn exposure were related to neurobehaviral performance, signal change on MRI scans, neurological features and profile of mood states (POMS), and influenced positively with age, alcohol and smoking history, and duration of Mn exposure, negatively with educational status. Serum Mn concentrations in combination with brain MRI scans, and perhaps a battery of neurobehaviral tests, appear to be the best way to monitor excessive exposure to Mn. These results are consistent with our knowledge on Mn action on the brain and are similar to the type of neurobehaviral dysfunction. They suggest that there may be age, educational status, and life style (alcohol and drinking history) differences with chronic environmental exposure. These findings suggest further evaluation, particularly on relationships between Mn exposure, aging, and susceptibility factors.

0.15% V was added to the modified Hadfield steel containing 3.2% Ni and after solution treatment, the steel was isothermally heated in the range 300℃ to 980℃. The precipitation of carbide and pearlitic constituent were tudied by means of microscopys and hardness test. The results obtained were as follows. (1) Carbide is more rapidly precipitated in the range of 600-800℃ and formed in the range of 350-910℃ with increasing heating time. (2) The precipitation of P.C. is more rapid at 700℃ and occurs in the range of 500-700℃ with increasing heating time. (3) The higher the heating temperature is the shorter the length of the acicular carbides becomes. (4) lncreased hardness is mainly caused by acicular carbide. The shape and the distribution of precipitates also bring about the hardness change.

In the analysis of locking range in an injection locked oscillator, Adler's differential equation is generally used. The equation is derived under the assumption that the amplitude of an injecting signal is very small compared to the oscillator signal. This paper has derived the general locking equation for an injection locked oscillator. With the aid of the equation, the injection locking range has been investigated. The experimental results have been nearly consistant with the theoretical results.

탄성력이 관계되는 역학적 에너지 보존에 관한 지도상의 문제점과 개선 방안

문충식,윤성현,권재술 한국교원대학교 과학교육연구소 1991 청람과학교육연구논총 Vol.1 No.1

현행 고등학교 물리 교과서와 대학 일반물리학 교재에 나타난 용수철 진자의 진동에서 역학적 에너지 보존에 관한 기준점 설정의 불명확성과 오해의 소지를 지적하고 이를 해결하기 위한 방안을 제시하였다. 혼란이 생기는 원인은 근본적으로 좌표 기준, 위치 에너지의 기준 설정에서 나타나는 것으로써 군등장인 경우, 거리에 비례하는 위치 에너지(mgx)이므로 기준을 어디에 잡아도 무방하나 그렇지 않는 탄성 위치 에너지의 경우(1/2)kx^2에는 주의를 요한다. 본 연구는 기준 위치 설정에 따라 위치 에너지 표현식이 다름을 보이고 이를 고등학교 및 대학 일반물리학 수준에서 지도할 수 있는 방안을 제시하고자 한다. A typical representation of elastic potential energy is (1/2)kx^2, where x represents the distance from the spring's unstratched end point. However, this representation will be correct only in a particular situation that the origin of the coordinate and the reference point of the potential energy are at x=0. Without this condition, the potential representation, (1/2)kx^2, is no longer correct. In this study, the misconceptions found in high school textbooks and university laboratory manual were exemined and presented a improved method to teach elastic potential energy. The generalized form of elastic potential energy with arbitrary reference point in coordinate system as well as potential energy was derived. To adopt this idea in high school level, a graphical method of deriving the generalized form of elastic potential energy was devised.
