대형녹조류인 Ulva pertusa는 전 세계 연안에 서식하는 저서성 종으로 대발생 또는 인공구조물에 착생되어 경제적, 사회적인 측면에서 문제를 야기시키고 있다. 착생생물을 제어하기 위해 신방오제인 ziram, diruon, zinc pyrithione(ZnPT), copper pyrithione(CuPT), DBNPA, triclosan 등이 방오도료로 사용 중이나, 대형 및 미세조류를 이용한 신방오제들의 방오능 검증과 기초적인 연구자료가 부족한 실정이다. 따라서 본 연구에서는 초기 우점착생종인 구멍갈파래의 포자를 이용하여 방오제의 효능을 검증하고 생체막 형성의 우점종인 미세조류 Nitzschia pungens를 이용한 방오능을 검증하였다. 구멍갈파래포자의 운동성 검증에서 ziram과 ZnPT는 diuron, CuPT, DBNPA, triclosan보다 50% 높은 운동성 억제를 나타내었고 착생 검증에서는 ziram이 가장 낮은 착생률 1%로 나타났으며 CuPT는 100 ㎍/L의 농도에서 다른 대조군에 비해 80%의 성장율 억제를 보였다. 본 연구의 결과로 신방오제의 방오능을 검증하여 향후 방오능 검증에 기초자료가 될 것으로 사료된다. Cosmopolitan green macroalga, Ulva pertusa is a widely spread species in most coastal waters. This benthic alga is appearing on marine objectives causes significantly economical and social problems. To prevent fouling organisms, new antifouling (AF) agents, such as ziram, diruon, zinc pyrithione, copper pyrithione, DBNPA and triclosan are used. However, the evaluations of new antifouling system of those agents strongly need more information on algae species for considering environment effect. Therefore, the purpose of this study was to evaluate the activity of antifouling system using Ulva spores and Nitzschia pungens. In addition, new AFS were evaluated the toxicity of microalga, Nitzschia pungens. In the motility of Ulva spores, ziram and zinc pyrithione were shown 50% higher inhibition motility than diuron, copper pyritione, DBNPA and triclosan. Ziram was appered the highest AFS of Ulva sore attachment. Copper pyrithione at the concentration of 100 ㎍/L was inhibited 80% growth rate comparison of control. In conclusion, each new AF agents showed their specific AF activities against marine organisms based on this work.

As a comprehensive study on the development of curriculum for environmental education based on the standpoint of ecology, the environmental issues within the science textbooks used in the elementary, middle and high school were analyzed with the special emphasis to four aspects; 1) the causes and 2) the examples of environmental pollution, 3) the principles of ecology, and 4) the endeavor to overcome environmental crises. The results confirm that the science textbooks were written on the basis of Environmentalism rather than Ecology, and the environmental issues were listed fragmentarily within the subjects related to science, and not systematically assembled between inter-subjects or -sciences. Therefore, the systematic and inter-scientific approaches based on the ecology will be needed for further and better environmental education. [environmental education, ecology, textbook analysis].

현성희,신현웅,Hyun, Sung-Hee,Shin, Hyun-Woung 한국미생물학회 2006 미생물학회지 Vol.42 No.1

조류의 효과적인 제어방법 개발의 일환으로 해양암석분말의 효과를 보기위하여 해양암석분말과 곰팡이 배양 상등액을 이용하여 해양조류 제거율을 조사하였다. 편조류인 H. akashiwo와 P.minimum는 해양암석 분말을 30g/1의 농도로 살포한 실험군에서 높은 구제효과를 나타내었고, P. oxalicum (HCLE-34)배양상등액 살포는 5 mg/l 살포군에서도 구제효과를 나타내었다. 혼합 살포군에서도 배양 상등액 단독 살포군에서와 동등한 정도의 구제효과를 나타내었고, 완충용액 (pH 2.8)은 15 mg/l 살포군에서 60분 경과 후 75%의 구제효과를 나타내었으나, 전자현미경적 관찰에서는 암석분말과 배양 상등액 혼합 살포군, 배양 상등액 살포군, 암석분말 살포군 및 완충용액 살포군 순으로 세포의 파괴정도가 관찰되었다. 이러한 결과는 암석분말과 곰팡이 배양상등액이 해양에서 발생되는 편조류의 대발생을 조절할 수 있는 물질로 작용함을 시사한다. To see effect of marine rock powder and fungal culture supernatant, we analyzed the biodegradation rates of harmful marine dinoflagellate, Heterosigma akashiwo and Prorocentrum minimum for developing the effective control methodology of algal bloom. Relatively low removal rates were observed in the treatment of marine rock powder or buffer solution alone. However, the lysis of H. akashiwo and P. minimum was enhanced in the combined treatments of marine rock powder with fungal supernatant. The effective concentration and exposure time of fungal supernatant for the lysis of H. akashiwo and P. minimum were 5 ml/l and 30 minutes, respectively. These results suggest that the fungal supernatant may be a biocontrol agent for the control of algal blooms in seawater.

The Activity Based Costing(ABC) means the process that makes clear how the actions and input resources have changed into service to calculate medical services costs. These days, the number of hospital which is using the ABC system is increasing to make their policy decision making efficient and run the hospitals more resonable. This study analyzes the unbalance in the level of health insurance service fee and the improvement plans based from 8 hospitals(ABC system) and 95 clinics(ABC survey). The cost recovery ratio has shown different levels according to each service type. A surgery service type recorded 76.8% and an evaluation & management service type is 84.6%, a treatment procedure type(85.8%), a function test type(91.6%) and health insurance fee even did not reach to the original cost. Meanwhile , a laboratory test type and imaging test type show high level of cost recovery ratio. they recorded 188.3% and 158.8%. Resultingly now of unbalance in the level of health insurance service fee accelerates supply of every test. so there is a need to make laboratory test type and imaging test type lower to keep balance with the surgery and medical service. These methods should be performed gradually with monitoring the unbalance fee ratio and for this, a panel medical institution have to be established for generalizations of studying result, fairness of selecting researching sample.

This paper aims to make a step-by-step strategy to formulate an unified health system by clarifying and overcoming challenges facing South and North Korea and to estimate costs needed for South Korea to assist North Korea to recover to normal health delivery system. We explored implications through literature review and estimated costs under the assumption that supportive activities be provided for 5 years in three ways: support for the development of health and medical care manpower; support for health and medical facilities; and support for the provision of both preventive and primary health care. Step-by-step strategy is formulated for a unified health system with the cost estimation resulting as follows: in case of basic scenario, a total of 3 trillion and 341 billion won (at present value of the year 2017) is in need for the 5-year period at the initial ‘recovery support stage’ with 135.9 billion won for the development of health and medical care manpower, approximately 2 trillion won for health and medical facilities, and 1.2 trillion won for the provision of both preventive and primary health care. Step-by-step approach is more realistic and applicable in formulating unified health system. Suggested stages are ‘recovery support stage,’ ‘system homogenization stage,’ and ‘unified system stage.’ Strategies at ‘recovery support stage’ suggested in this paper need to be pursued and followed by those at ‘system homogenization stage’ and ‘unified system stage.’

The purpose of this study is to find out factors affecting patient moving to receive medical service. This study is analyzed by multi-level model with patient and hospital level by using SAS 9.3. Total number of patients is 600,000 persons for inpatients and 550,000 patients for outpatients. The degree of the factors, which is combined with personnel factor and hospital factor, can be analyzed by Intra-Class Correlation (ICC). The percentage of group(hospital) level variance of the total variance for out-bound moving case are 30.6% at inpatients, and 28.3% at outpatients. And the percentage of hospital level variance of the total variance for moving distance, are 26.7%, 32,5% respectively. Conclusionally, although the main factor of moving is patient level, hospital is also very important factor to make decision to go out-bound. It contributed to about 1/3 for hospital choice. And, when the one make decision, he will consider the hospital type, number of bed, and training institute in hospital level. Through this study to find out hospital factors affecting patient moving for medical service, it must be continued to find out which factors have more influence to choice the hospital among disease type after this.
