강원도는 오랫동안 금속, 비금속, 석재 및 석탄과 같은 지하자원들을 공급하는 국내 주요생산지로 알려져 왔으나, 장기적인 채광과 비 계획적인 생산으로 인하여 매장량이 고갈되고 있으며, 대외적으로 생산 경쟁력 마저 잃어가고 있다. 이러한 문제점에 대한 해결방안의 일환으로 본 연구에서는 강원도내에 산재되어 있는 지하자원의 분포, 자원 생산시설 및 생산량, 경제성, 자원개발, 환경문제 등 자원관리에 필요한 제반사항을 수행할 수 있는 강원지역 자원 종합관리 GIS 시스템을 개발하였다. 이 시스템의 개발은 방대한 양의 정보 조사 및 저장, 오랜 개발기간, 많은 소요인력 및 개발 비용이 요구되기 때문에 본 연구에서는 조기에 자원관리 GIS 시스템을 개발하여 이와 관련된 생산 및 연구 분야에 조기에 적용할 수 있도록, 일차년도에는 현재 석재복합 신소재제품 연구센터의 집중적 연구대상 지역인 태백지역에 대한 탄광지역을 중심으로 자원 종합관리 GIS 시스템을 개발하였다. The Kangwon province has been well-known to be one of major underground resource producing districts which are mainly supplying metals, non-metals, stones, and coals. However, due to the long-term mining and unplanned production, the natural resource reserves have been rapidly drained and oversea production competition has been losing. In this study, we has developed a GIS system for regional resource management in the Kangwon province, which can operate, maintain, and manage the distribution of underground resources, resource production facilities, production and economic development, and environmental issues. The development of this system requires the collection, analysis, evaluation, and storage for a huge amount of research data, and in addition, the long period of time, the big research man power, and big development cost. Accordingly, to shorten the development period of time and to early apply itself to production, this stage of study has been intensively developed a regional resource GIS system for managing the mines scattered in the Tabak province, which is one of hottest RRC's research areas.

Purpose: Many CEOs have often introduced various types of management innovation for the firm``s profitability improvement. If the firm is, however, in a situation in which the firm is not ready to adopt those management innovations, it is not possible to achieve the goal of profit enhancement. In this study, we analyze the relationship between the preliminary elements of management innovation and profitability, and want to introduce the key success factors of management innovation. Methodology/Approach: After investigating preliminary elements of the management innovation adoption through existing literature review, we conducted a questionnaire survey to Korean K-company. Then, by utilizing the structural equation modeling with AMOS, we analyzed the impact of preliminary elements of the management innovation adoption on the profitability. Findings: We found out that there are main preliminary elements of the management innovation adoption directed to profitability enhancement From this finding, it would be possible to assist promoting successful management innovation of the company. Research Limitation/implication: This research has a limitation on that the findings are based on the analysis with subjective measures rather than objective ones for profitability. There is a need for further studies using objective measures such as an actual percentage figure for sales growth or profit change. Originality/Value of paper: By searching and enhancing the preliminary elements of management innovation affecting the profitability, it would be possible to reduce the innovation failure in the future business.

Flowcytometry를 이용한 DNA함량차이에 의한 X-, Y-정자의 분리와 착상전 HY항원과 PCR기술을 이용한 수정란의 성판정기술은 축산분야에 새롭게 적용되고 있다. 최근 정자의 90%이상 정확하게 성판정되어 분리되어지며 살아있는 정자의 분괴속도도 시간당 5,000이내 정도 된다. 그러나 빠르게 분괴된 정자의 일반적인 인공수정에는 충분하지 못한 실정이다. 그러르모 성판정된 정자 또는 수정란 화수 및 이식을 위해 개발되어져야 한다. Sex preselection through the separation of X- and Y-sperm based on DNA contents using flowcytometry and embryos using PCR technique and HYantigens at preimplantation is now a reality in livestocks. Sperm can be sexed with 90% accuracy by flowcytometry/cell sorting. The current speed of sexing is about 5,000 live sperm of each sex per second, remarkably fast considering that each sperm is individually sexed. Fast sperm sexing is not enough to use standard numbers of sperm per artificial insemination dose. Therefore, micro insemination using laparoscopy and ultrasonography must be improved for sexed sperm or embryo recovery and transfer.

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.

28세 남자의 후천성 면역 결핍증 환자에서 S. pneumoniae 폐렴이 합병되어 사망한 1예를 경험하여 부검소견과 함께 보고하는 바이다. Pulmonary infections such as Pneumocystis carinii, cytomegalovirus, and tuberculosis are a major cause of morbidity and mortality in patients with human immunodeficiency virus(HIV) infection. Patients with HIV infection are at increased risk for bacterial pneumonia in addition to opportunistic infection. Although in a primary defect, HIV infection is associated with substantial dysfunction of humoral immunity, which predisposes patients to bacterial infections, particularly with encapsulated organisms, such as Streptococcus pneumoniae. We report a case of 28 year-old Korean male with HIV infection who died of respiratory failure due to pneumococcal pneumonia with autopsy findings.
