Objective : The purpose of this study was to find the relationship between the follow-up management status for medical problem to be treated and various characteristics of some workers at transportation business. Methods : A questionnaire survey was made toward 183 workers with medical problem(C and D2) among 945 examine in 1997. Results: Sixty four point five percent of surveyee received the examination result report and 40.5% were explained about the result 80.3% of surveyee answered that they knew the result of health examination. Most workers felt the necessity of the health examination, but 54.1% were dissatisfied with present health examination system and 66.7% pointed it out as nominal The rate of follow-up management for the medical problem was 62.8% By the multiple logistic regression the follow-up management rate for those who knew the health examination result were 2.98 times higher than those who didn't know the result (OR=2.98, 95% CI 1.41~6.29) The rate for those who perceived the medical problem already were 2.64 times higher than those who perceived the problem for the first time (OR=2.64, 95% CI 1.13~6.15). The rate for those who had subjective symptoms were 2.83 times higher than those who didn't have subjective symptoms. Conclusion : sixty two point eight percent of workers with medical problem performed the follow-up management and perception of health examination result, perception of the problem in the past and experience of subjective symptoms were related with the follow-up management.

Along with development of internet and a networking technology, security threat elements such as hacking, computer virus, Internet worm are increasing too day by day. To block these threat factor, great many firewall and intrusion detection system etc, were developed. However, can not depart in all threats even though introduce these security system. There is fundamental limit that a present server security technology because operate in application level, can have bug that can trench, and does not protect oneself if system encounters hacking. However, it is network base intrusion detection system that do essential indispensability in composition of network system that can come to foundation of this operating system. In this paper, study intrusion detection system of network base faithfully and does for that purpose that embody directly.

As crops recently can be cultivated all the year in greenhouses, we need to improve the environment in which crops are able to grow in the summer. Therefore, in this study, we quantitatively got the cooling effects of 4 single span plastic greenhouses in the following ways : by spraying mist or sprinkler, or by opening the side window. and with those variables, we simultaneously did experiments at 4 greenhouses under equivalent conditions to reduce the temperature of the greenhouses in the summer. The results of the experiments are as following : 1) The temperatures of the greenhouses were effectively reduced by both spraying mist and sprinkler. 2) When the mist is intermittently sprayed. the indoor temperature has decreased by 4 degrees centigrade, meanwhile, in the greenhouse to make experiments using sprinkler, the temperature of that has been reduced by 2 degrees centigrade. Therefore, we can see the cooling effects of smaller mist in size as more effective than those of sprinkler. 3) When the greenhouse is naturally ventilated by opening the side window, we have to apply another cooling system because the indoor temperature is higher than the outdoor one.

Primary systemic amyloidosis (AL amyloidosis) is an uncommon disease characterized by the accumulation in vital organs of a fibrillar protein consisting of monoclonal immunoglobulin light chains. It is a plasma cell dyscrasia usually accompanied by a bone marrow plasmacytosis and an M component in the serum or urine. The presenting features of AL amyloidosis are protean and frequently nonspecific, but the diagnosis is rarely made until symptoms or signs referable to a particular organ appear. The amyloid deposits cause cardiac or renal dysfunction and, ultimately, death. We report a case of AL amyloidosis, presented with unexplained diarrhea and abdominal pain for eight months, documented by a renal biopsy, and review the previous literatures

기존의 특수건강진단과 작업환경측정을 통한 직업병 관리가 진폐증, 소음성난청 등의 소수 특정질환에 국한되고 실제 직업병 발생 규모 파악이나 신종 직업병의 발견에 한계를 보인다는 사실은 산업의학전문가들 사이에서도 공감을 이루고 있다. 미국과 영국 등에서의 직업성질환 감시체계에 대한 경험은 우리 나라의 직업성질환 감시체계 구축에도 새로운 자극제가 되면서, 1998년이후 인천, 대전, 여천, 구미, 부울경 지역에서 지역 직업성질환감시체계를 산업보건관리의 중요한 시스템으로 구축하려는 노력이 확산되고 있다. 새로이 구축되어지는 이들 지역 직업성질환 감시체계는 감시하고자 하는 대상질환, 활용 가능한 인적자원 및 자료원, 지역 의료체계의 특수성 등에 따라서 목적과 방법을 달리하면서 독특한 형태로 발전을 하고 있다. 각 지역단위 감시체계들이 그 상황에 맞게 독특한 목적과 전략들을 발전 시키면서도, 향후 발전할 국가적인 차원의 직업성질환 감시체계 구축을 위하여 직업성질환 감시의 기본 전략 등을 공유하는 등의 노력이 필요하다. 환례 정의 및 기본적인 등록 서식의 공유, 직업성질환 감시 자료원의 발굴, 공동의 정보 네트워크 및 직업성질환 감시 데이터베이스 구축 등 직업성질환 감시활동을 지원하기 위한 여러 기초 인프라 구축에 힘을 모아야 할 것이다. 우리 나라에서 직업성질환 감시체계를 성공적으로 구축하기 위해서는 수집된 자료의 질 관리를 위한 직업성질환 감시의 원칙 제정과 감시 전략의 공유 등이 필요하며, 전국적인 직업성질환 감시체계의 하부구조라고 할 수 있는 지역감시체계의 기초 토대 마련과 강화작업이 절실하게 필요하다.

Surveillance programs in the workplace can be used to monitor trends of illness, injury, or exposure to workplace hazards. In such activity, surveillance data are developed to assess variations in rates between (1) different industrial groups (2) different geographic areas, and/or (3) different time periods. In this way, surveillance of health or exposure trends can be used to evaluate the efficacy of programs designed to control occupational hazards. Medical screening programs have been existed for the identification of cases of occupational diseases such as pneumoconiosis, noise-induced hearing loss in Korea. However, the occurrence of some types of occupational illnesses and injuries has been seriously underestimated in Korea. The typical examples of underestimated occupational illness and injury are occupational asthma, occupational skin diseases, occupational musculoskeletal diseases, and occupational cancer. This underdiagnosis and underreporting of occupational illnesses and injuries subsequently contribute to difficulties in performing effective control of occupational hazards and implementing intervention programs to protect workers. To overcome this problem, a variety of occupational disease surveillance systems are being constructed for the identification of cases of occupational illness and injury and the monitoring of trends. In Inchon, Taejon, and Yochon, regional occupational surveillance system is being built for preventing occupational hazards and for enforcing occupational disease prevention programs in local level. Nation-wide occupational surveillance system is also being built with specific target disease such as occupational contact dermatitis, occupational asthma, or occupational musculoskeletal disorder. All of these systems have same difficulties in maintaining professional staff that could respond to the incoming reports. They have insufficient sources in collecting valid data. These programs should not be conducted as separate activities, but rather integrated into a comprehensive program as a national surveillance system designed to control workplace hazards and protect worker health in the national level. Further efforts are needed to develop available surveillance resources such as medical providers' reports, hospital medical records, medical examination data of employees, and biological monitoring data, worker's compensation data. Appropriate preventive intervention will also be needed to control workplace hazards and protect worker health using surveillance data.

Pancreas is known for the unfavorable soil to the metastatic carcinoma, and pancreatic metastasis is achieved after systemic dissemination was developed. The primary tumors of metastatic pancreatic carcinoma are breast, lung, Iymphoma, malignant melanoma, leukemia, stomach. and colon. The breast carcinoma is the commonest tumor to metastasize to pancreas and both tumors are related to estrogen receptor for tumor growth. In the present case, tumor cells had small round nucleus and showed indian file infltrating pattern and lack of cohesion, which are seen in infiltrative breast carcinoma. The patient was underwent radical mastectomy due to infiltrative ductal carcinoma three years ago. And also the tumor cells showed nuclear reactivity to immunostaining for estrogen receptor In combination of the histopathologic. immunohistochemical, and her past history, we concluded that breast carcinoma was metastasized to pancreas, and we report a case of metastatic pancreatic carcinoma from breast with review of literatures.

Hemorrhagic fever with renal syndrome(HFRS)is an infectious disease showing diverse clinical manifestations according to different serotypes of hantavirus. On the assumption that the antigenicity, nucleotide and amino acid sequence diversity of hantaviruses, as well as immune response diversity of individual KHF patients may be present, this study was performed to analyse the genetic diversity of hantaviruses isolated from patients with KHF. In the 13 samples hantaviral RNAs were extracted, cDNAs of partial M segment were amplified by RT-PCR using genus-reactive primer, amplified cNNAs were analyzed by direct sequencing method, and then the nucleotide and deduced amino acid sequences were compared with previously known sequences of four serotypes of hantavirus isolated from rodent hosts and each other by the computer assistance. The results were as follows. The nucleotide and amino acid sequences of 11 samples among the 13 human isolates showed 90.3∼95.5%, 86.7∼97.9% the other 1 samples 82.7%, 71.9% homology respectively to those of Hantaan virus 76-118 strain, and another 1 sample showed 83.7%, 75.3% homology respectively to those of Seoul virus B1 strain isolated from rodent host. The nucleotide and amino acid sequences of 7 among 12 Hantaan samples showed differences within 5%, 10% respectively each other and high genetic similarities, but those of the oehr 5 among 12 Hantaan samples showed low genetic similarities each other. In conclusion, hantaviruese isolated from KHF patients showed genetic diversity compared with previously known hantaviruses isolated from rodent hosts.
