이 글은 2015년 메르스 사태를 계기로 2015. 6. 20. 의료법과 감염병예방법의 관련 조항을 분석하고 그 문제점을 적시하여 입법론을 전개한 발표문을 바탕으로 한 것이다. 발표에서 우선 감염병 분류 체계의 합리화를 지적하였다. 이 지적은 발표 직후의 '개정법률'에서 반영되었지만 여전히 유형의 중복성을 제거하는 등 그 합리화를 위한 작업이 필요하다. 한편 감염병의 신고 내지 보고 체계에 관하여 신고 내지 보고의 의무자와 상대방 및 그 시기 등의 관점에서 합리화를 위한 입법적 조치가 필요함을 언급하였다. 감염병의 대응 조치로 도입의 필요성이 주장된 의료기관의 폐쇄에 관한 방역조치는 '개정법률' 제47조에서 반영되었다. 하지만 방역조치의 권한이 여전히 중앙정부와 지방정부에 병렬적으로 중첩적으로 분배되어 있다는 점은 문제이다. 그 권한 귀속의 합리화는 중앙정부로의 일원화에서 찾아야 하며, 그 논거와 함께 그 필요성을 지적하였다. 한편 역설한 점은 장관 등 중앙정부 기관장이 그러한 폐쇄 명령이나 격리 명령을 내리는 경우, 그로 인하여 의료기관이나 환자가 입은 재산상 손실의 전부 또는 일부를 국가가 전보해 줄 의무를 지도록 하는 규정이 필요함이다. 이는 권한 귀속과 연계되는 것인바, 방역조치의 권한 귀속 주체와 그 손실전보를 위한 재원의 관리주체가 일원화되어야 할 필요성을 역설하였다. 방역조치 권한의 실효성은 그 손실 전보의 보장이 담보하는 것이며 이는 국부(國富)의 차원에서 접근해야 한다는 점에서 중앙정부로의 일원화에 관한 입법론을 전개하였다. 나아가서 감염병으로 인한 개인이나 의료기관의 재산상 손실은 민법의 일반불법행위의 법리에 맡기는 것이 비합리적이라는 점을 논술하였다. 이 역시 중앙정부의 재정에 의한 전보와 고의 내지 미필적 고의가 인정되는 개인에 대한 국가의 구상권 행사로 민사 분쟁을 해결함이 피해자의 구제에 합리적인 이유를 들어서 입법론을 제시하였다. 이번 메르스 사태에 대한 향후 조사에서 개선이 필요한 내용이 더 밝혀질 수 있을 것이다. 그러한 논의에 따라 보다 합리적이고 구체적인 입법론이 전개되어야 할 것이다.

목 적 : 집중 치료를 받고 있는 환자들에서 MDR-HAI이 전세계적으로 중요한 문제로 인식되고 있다. 그러나 이와 관련하여 소아 환자들을 대상으로 한 연구는 성인에 비해 상대적으로 부족하다. 본 연구에서는 단일 대학병원 중환자실에 입원한 소아환자를 대상으로 MDR-HAI의 발생률과 연관인자를 알아보고자 하였다. 방 법: 2009년 1월부터 2010년 12월까지 본원 환자실에서 3일 이상 입원치료 하였던 135명의 소아 환자를 대상으로 입원기록을 후향적으로 검토하였다. 원내감염을 MDR-HAI과 non-MDR-HAI의 두 군으로 나누어 각각 임상적 특징과 여러 연관인자들을 비교하였다. 결 과: 39명의 환자에서 45례의 중환자실내 원내감염이 발생하였다. 원내감염의 발생률은 중환자실 재원 1,000일당 47.7이었다. 45례 원내감염 중 36례(80.0%)가 다제 내성균에 의한 감염이었다. A. baumannii는 MDR-HAI군에서 더 흔하게 검출되었다(54.5% vs. 8.3%; P=0.007). 중환자실 입원 적응증 중 내과적 질환, 인공 호흡기 치료, 도뇨관 삽입, 이전 광범위 항생제 사용은 MDR-HAI군에서 통계적으로 유의하게 높았다. 회귀분석 결과 이전 광범위 항생제 사용만이 MDR-HAI의 독립적 위험인자였다. 결 론 : 중환자실내 원내감염의 발생률은 이전에 보고된 것보다 높았으며, 이전 광범위 항생제 사용이 MDR-HAI의 독립적 위험인자였다. 향후 중환자실에 입원한 소아 환자에게 발생한 MDR-HAI의 정확한 특징을 확인하기 위해 추가적인 연구가 필요할 것으로 생각된다.

초등(elementary), 중등(secondary)교육에 이어지는 대학 및 직업 교육을 총칭하여 고등(tertiary) 교육이라고 한다. 본 연구는 미국에서의 고등(tertiary)수학과 한국에서의 고등수학 초기 발전과정을 비교 연구한다. 미국 대학에서의 수학 강좌개설의 역사를 살펴보면 하버드대 학장인 던스터가 1640년 산술과 기하를 예비졸업생들을 대상으로 지도한 기록이 남아있다[10]. 이 기록에 의하면 미국 대학과정의 수학은 1636년 설립된 하버드 대학에서 1640년부터 실질적인 강의가 시작되었다고 할 수 있다. 미국의 수학자로는 1870년 'Linear Associative Algebra'를 발간한 하버드의 벤자민 퍼스가 비로소 수학에 대한 학술적인 기여를 통하여 처음으로 유럽학계의 주목을 받는다. 미국의 경우 세 번째 연구중심대학으로 시작한 시카고대학의 성장과 함께 학술적으로 유럽 수학계의 인정을 받고 미국 수학연구의 존재를 학계에 알린 미국인 수학자로 G.D. 버코프를 꼽는다. 1912년 하버드대 수학과 교수로 부임하여 하버드대 수학과의 역할을 교육에서 연구로 바꾸는데 결정적인 역할을 한다. 즉, 미국 수학이 교육에서 연구 단계로 진화하는 과정에 무려 200년 이상이 걸렸다는 사실을 확인할 수 있다. 하버드에서 대학 과정이 설립될 즈음 조선에서의 고등수학의 상황은 어떠하였을까? 한반도에서는 조선산학과 구한말의 대학부 및 연희 전문학교 수물과를 거쳐 1945년 8월 2차 세계대전이 끝나면서 비로소 일제식민통치하에서 벗어난 1945년 4년제 대학에 수학과가 처음 설립된다. 일제 강점기에는 중학교와 전문학교 이과에서 일부 직업교육 또는 대학수학이 다루어졌다. 한국의 경우 경성대의 이임학이 1947년 막스 존의 미해결 문제를 풀며 한국 근대수학자의 존재를 서양에 알리게 된다. 본 연구에서는 미국과 한국의 초기 고등수학 발전과정을 수학자 중심으로 비교 연구하여 발전 단계를 진단한다.

Rheumatoid arthritis is the one of the chronic diseases, one of its major symptoms is a chronic pain. Despite developing medical treatment and surgical techniques, it is suggested that to control the pain is the goal of the treatment. But pain is an inner experience and even those closest to the patient cannot truly observe its progress or share in its suffering. The National Academy of Sciences Institute of Medicine's report on Pain and Disability concluded that there is no objective measure of pain-(exactly) no pain thermometer-nor can there ever be one, because the experience of pain is inseparable from personal perception and social influence such as culture. To explore chronic pain experience is to understand the process and property of the patient's perception of pain through the response to pain, the coping with pain, and the adaptation to pain. Therefore a qualitative study was conducted in order to gain an understanding of pain experience of patients with RA in korea. I used naturalistic inquiry as a research methodology, which had 5 axioms, the first is that realities are multiple, constructed, and holistic, the second is that knower and known are interactive, inseparable, the third is only time and context bound working hypotheses(idiographic statements) are possible, the forth is all entities are in a state of mutual simultaneous shaping, so that it is impossible to distinguish causes from effects and the last is that inquiry is value-bound. Purposive sampling was conducted as a sampling. 20 subjects who experienced pain over 10 years, lived in middle-sized city and big city in Korea, and 17 women and 3 men. The subject's age was from 32 to 62 (average 48.8), all were married, living with their spouse and children, except two-one divorced and the other widow before they became ill. I collected data using In depth structured interview. I had interviews two or three times with each subject, and the interviews were conducted at each subject's home. Each interview lasted about two hours an average. A recording was taken with the consent of the subject. I used inductive data analysis-such as unitizing and categorizing. unitizing is a process of coding, whereby raw data are systematically transformed and aggregated into units. Categorizing is a process wherby previously unitized data are organized into categories that provide descriptive or inferential information about the context or setting from which the units were derived. This process is used constant comparative method. The pain controlling process is composed of behavior of pain control. The behaviors of pain control are rearranging of ADL, hiddening role conflict, balancing treatment, and changing social relation. Rearranging of ADL includes diet management, sleep management, and the adjustment of daily life activities. The subjects try to rearrange their daily activities by modified style of motions, rearranging time span & range of activities, using auxillary facilities, and getting help in order to keep on the pace of daily life. Hiddening role conflict means to reduce conflicts between sick role and their role as a family member. In this process, the subjects use two modes, one is to control the pain complaints, and the other is to internalize the value which is to stay home is good for caring her children and being a good mother. To control pain complaints is done by 'enduring', 'understanding' the other family members, or making them undersood in order to reduce pain. Balancing treatment is composed of two aspects. One is to keep the pain within the endurable level, the other is to keep in touch with medical personnel in order to get the information of treatment and emotional support. Changing social relation is made by information seeking and sharing, formation of mutual support relation, and finally simplification of social relationships. The subjects simplify their social relationships by refraining from relations with someone who makes them physically and psychologically strained. In particular the subjects are apt to avoid contact with in-laws, and the change of relation to in-laws results in lessening the family boundary. In the course of this process, they confront the crisis of family confict result in family dissolution. This crisis is related to the threat of self-existence. Findings from this study contribute to understanding the chronic pain experience. To advance this study, we should compare this result with other cases in different cultural contexts. I think to interpret these results, korean cultural background should be considered. Especially the different family concept, more broader family members and kinship network, and the traditional medical knowledge influences patients' behavior.

According to Wikipedia, virtual reality (VR) is defined as a technology that allows a user to interact with a computer-simulated environment. Due to a rapid growth in information technology (IT), the cost of virtual reality has been decreasing while the utility of virtual reality advertisements has dramatically increased. Nevertheless, only a few studies have investigated the effects of virtual reality advertisement on consumer behaviors. Therefore, the objective of this study is to empirically examine the effects of virtual reality advertisement. Compared to traditional online advertisements, virtual reality advertisement enables consumers to experience products realistically over the Internet by providing high media richness, interactivity, and telepresence (Suh and Lee, 2005). Advertisements with high media richness facilitate consumers' understanding of advertised products by providing them with a large amount and a high variety of information on the products. Interactivity also provides consumers with a high level of control over the computer-simulated environment in terms of their abilities to adjust the information according to their individual interests and concerns and to be active rather than passive in their engagement with the information (Pimentel and Teixera, 1994). Through high media richness and interactivity, virtual reality advertisements can generate compelling feelings of "telepresence" (Suh and Lee, 2005). Telepresence is a sense of being there in an environment by means of a communication medium (Steuer, 1992). Virtual reality advertisements enable consumers to create a perceptual illusion of being present and highly engaged in a simulated environment, while they are in reality physically present in another place (Biocca, 1997). Based on the characteristics of virtual reality advertisements, a research model has been proposed to explain consumer responses to the virtual reality advertisements. The proposed model includes two dimensions of consumer responses. One dimension is consumers' rational response, which is based on the Information Processing Theory. Based on the Information Processing Theory, product knowledge and perceived risk are selected as antecedents of intention to purchase. The other dimension is emotional response of consumers, which is based on the Attitude-Structure Theory. Based on the Attitude-Structure Theory, arousal, flow, and positive affect are selected as antecedents of intention to purchase. Because it has been criticized to have investigated only one of the two dimensions of consumer response in prior studies, our research model has been built so as to incorporate both dimensions. Based on the Attitude-Structure Theory, we hypothesized the path of consumers' emotional responses to a virtual reality advertisement: (H1) Arousal by the virtual reality advertisement increases flow; (H2) Flow increases positive affect; and (H3) Positive affect increases intension to purchase. In addition, we hypothesized the path of consumers' rational responses to the virtual reality advertisement based on the Information Processing Theory: (H4) Increased product knowledge through the virtual reality advertisement decreases perceived risk; and (H5) Perceived risk decreases intension to purchase. Based on literature of flow, we additionally hypothesized the relationship between flow and product knowledge: (H6) Flow increases product knowledge. To test the hypotheses, we conducted a free simulation experiment [Fromkin and Streufert, 1976] with 300 people. Subjects were asked to use the virtual reality advertisement of a cellular phone on the Internet and then answer questions about the variables. To check whether subjects fully experienced the virtual reality advertisement, they were asked to answer a quiz about the virtual reality advertisement itself. Responses of 26 subjects were dropped because of their incomplete answers. Responses of 274 subjects were used to test the hypotheses. It was found that all of six hypotheses are accepted. In addition, we found that consumers' emotional response has stronger impact on their intention to purchase than their rational response does. This study sheds much light into practical implications for both IS researchers and managers. First of all, while most of previous research has analyzed only one of the customers' rational and emotional responses, we theoretically incorporated and empirically examined both of the two sides. Second, we empirically showed that mediators such as arousal, flow, positive affect, product knowledge, and perceived risk play an important role between virtual reality advertisement and customer's intention to purchase. In addition, the findings of this study can provide a basis of practical strategies for managers. It was found that consumers' emotional response is stronger than their rational response. This result indicates that advertisements using virtual reality should focus on the emotional side, and that virtual reality can be served as an appropriate advertisement tool for fancy products that require their online advertisements to give an impetus to customers' emotion. Finally, even if this study examined the effects of virtual reality advertisement of cellular phone, its findings could be applied to other products that are suited for virtual experience. However, this research has some limitations. We were unable to control different kinds of consumers and different attributes of products on consumers' intention to purchase. It is, therefore, deemed important for future research to control the consumer and product types for more reliable results. In addition to the consumer and product attributes, other variables could affect consumers' intention to purchase. Thus, the future research needs to find ways t control other variables.

As the utilization of information technology and the turbulence of technological change increase in organizations, the adoption of IT outsourcing also grows to manage IT resource more effectively and efficiently. In this new way of IT management technique, service level management(SLM) process becomes critical to derive success from the outsourcing in the view of end users in organization. Even though much of the research on service level management or agreement have been done during last decades, the performance of the service level management process have not been evaluated in terms of final objectives of the management efforts or success from the view of end-users. This study explores the relationship between SLM maturity and IT outsourcing success from the users' point of view by a analytical case study in four client organizations under an IT outsourcing vendor, which is a member company of a major Korean conglomerate. For setting up a model for the analysis, previous researches on service level management process maturity and information systems success are reviewed. In particular, information systems success from users' point of view are reviewed based the DeLone and McLean's study, which is argued and accepted as a comprehensively tested model of information systems success currently. The model proposed in this study argues that SLM process maturity influences information systems success, which is evaluated in terms of information quality, systems quality, service quality, and net effect proposed by DeLone and McLean. SLM process maturity can be measured in planning process, implementation process and operation and evaluation process. Instruments for measuring the factors in the proposed constructs of information systems success and SL management process maturity were collected from previous researches and evaluated for securing reliability and validity, utilizing appropriate statistical methods and pilot tests before exploring the case study. Four cases from four different companies under one vendor company were utilized for the analysis. All of the cases had been contracted in SLA(Service Level Agreement) and had implemented ITIL(IT Infrastructure Library), Six Sigma and BSC(Balanced Scored Card) methods since last several years, which means that all the client organizations pursued concerted efforts to acquire quality services from IT outsourcing from the organization and users' point of view. For comparing the differences among the four organizations in IT out-sourcing sucess, T-test and non-parametric analysis have been applied on the data set collected from the organization using survey instruments. The process maturities of planning and implementation phases of SLM are found not to influence on any dimensions of information systems success from users' point of view. It was found that the SLM maturity in the phase of operations and evaluation could influence systems quality only from users' view. This result seems to be quite against the arguments in IT outsourcing practices in the fields, which emphasize usually the importance of planning and implementation processes upfront in IT outsourcing projects. According to after-the-fact observation by an expert in an organization participating in the study, their needs and motivations for outsourcing contracts had been quite familiar already to the vendors as long-term partners under a same conglomerate, so that the maturity in the phases of planning and implementation seems not to be differentiating factors for the success of IT outsourcing. This study will be the foundation for the future research in the area of IT outsourcing management and success, in particular in the service level management. And also, it could guide managers in practice in IT outsourcing management to focus on service level management process in operation and evaluation stage especially for long-term outsourcing contracts under very unique context like Korean IT outsourcing projects. This study has some limitations in generalization because the sample size is small and the context itself is confined in an unique environment. For future exploration, survey based research could be designed and implemented.

Social commerce has been gaining explosive popularity, with typical examples of the model such as Groupon and Level Up. Both local business owners and consumers can benefit from this new e-commerce model. Local business owners have a chance to access potential customers and promote their products in a way that could not have otherwise been easily possible, and consumers can enjoy discounted offerings. However, questions have been increasingly raised about the value and future of the social commerce model. A recent survey shows that about a third of 324 business owners who ran a daily-deal promotion in Groupon went behind. Furthermore, more than half of the surveyed merchants did not express enthusiasm about running the promotion again. The same goes for the case in Korea, where more than half of the surveyed clients reported no significant change or even decrease in profits compared to before the use of social commerce model. Why do local business owners fail to exploit the benefits from the promotions and advertisements through the social commerce model and to make profits? Without answering this question, the model would fall under suspicion and even its sustainability might be challenged. This study aims to look into problems in the current social commerce transactions and provide implications for the social commerce model, so that the model would get a foothold for next growth. Drawing on justice theory, this study develops theoretical arguments for the effects of transaction characteristics on consumers' distributive justice and purchase intention in the social commerce. Specifically, this study focuses on two characteristics of social commerce transactions-the discount rate and the purchase rate of products-and investigates their effects on consumers' perception of distributive justice for discounted transactions in the social commerce and their perception of distributive justice for regular-priced transactions. This study also examines the relationship between distributive justice and purchase intention. We conducted an online experiment and gathered data from 115 participants to test the hypotheses. Each participant was randomly assigned to one of nine manipulated scenarios of social commerce transactions, which were generated based on the combination of three levels of purchase rate (high, medium, and low) and three levels of discount rate (high, medium, and low). We conducted MANOVA and post-hoc ANOVA to test hypotheses about the relationships between the transaction characteristics (purchase rate and discount rate) and distributive justice for each of the discounted transaction and the regular-priced transaction. We also employed a PLS analysis to test relations between distributive justice and purchase intentions. Analysis results show that a higher discount rate increases distributive justice for the discounted transaction but decreases distributive justice for the regular-priced transaction. This, coupled with the result that distributive justice for each type of transaction has a positive effect on the corresponding purchase intention, implies that a large discount in the social commerce may be helpful for attracting consumers, but harmful to the business after the promotion. However, further examination reveals curvilinear effects of the discount rate on both types of distributive justice. Specifically, we find distributive justice for the discounted transaction increases concavely as the discount rate increases while distributive justice for the regular-priced transaction decreases concavely with the dscount rate. This implies that there exists an appropriate discount rate which could promote the discounted transaction while not hurting future business of regular-priced transactions. Next, the purchase rate is found to be a critical factor that facilitates the regular-priced transaction. It has a convexly positive influence on distributive justice for the transaction. Therefore, an increase of the rate beyond some threshold would lead to a substantial level of distributive justice for the regular-priced transaction, threrby boosting future transactions. This implies that social commerce firms and sellers should employ various non-price stimuli to promote the purchase rate. Finally, we find no significant relationship between the purchase rate and distributive justice for the discounted transaction. Based on the above results, we provide several implications with future research directions.

항산화 활성이 우수할 것으로 기대되는 남구절초($Dendranthema$ $zawaskii$ var. $yezoense$)와 코스모스($Cosmos$ $bipinnatus$) 지상부의 항산화 물질 함량 및 항산화 활성을 증가시킬 수 있는 효율적인 추출방법을 개발하기 위하여 본 연구를 시행하였다. 추출수율은 두 종 모두 초음파추출물에서 우수하였으며, 환류냉각추출물보다 1.11-1.92배 증가되었다. 총 폴리페놀과 총 플라보노이드의 함량 또한 초음파추출물에서 우수하였다. 총 폴리페놀은 함량은 45분 동안 초음파추출한 코스모스에서 $80.70mg{\cdot}g^{-1}$ DW로 가장 높았고, 총 플라보노이드 함량은 45분 동안 초음파추출한 남구절초에서 $50.41mg{\cdot}g^{-1}$ DW로 가장 높았다. DPPH radical 소거능은 추출방법에 따른 차이가 없거나 환류냉각추출물이 다소 우수한 경향을 보였으며, 환류냉각추출한 코스모스 지상부 추출물의 소거능($RC_{50}=0.135mg{\cdot}mL^{-1}$)이 가장 우수하였다. ABTS radical 소거능은 남구절초와 코스모스 모두 초음파 15분 추출물에서 가장 우수하였다(각각 $RC_{50}$=0.159, $0.139mg{\cdot}mL^{-1}$). $Fe^{2+}$ chelating효과는 30분 동안 초음파추출한 남구절초 지상부에서 가장 높았다($RC_{50}=0.803mg{\cdot}mL^{-1}$). 남구절초 지상부 추출물의 지질과산화 억제활성은 환류냉각추출물에서 가장 우수하였으나, 코스모스 지상부 추출물의 지질과산화 억제활성은 45분 동안 초음파추출한 처리구에서 가장 높았다. 연구 결과, 식물 종과 목표로 하는 항산화 효과에 따라 추출방법을 달리해야 할 것으로 생각되었다.

본 조사는 낙동강 유역의 홍수피해를 저감하고, 경북 중부지역의 안정적인 용수를 공급하기 위해 경북 군위군 고로면에 건설 중인 화북댐의 상 하류 어류조사를 통하여 댐 건설이 하천유역에 특히 수 생태계내의 어류군집에 미치는 영향유무를 파악하여 종 다양성을 보전하고 하천의 건강성을 유지하기 위한 기초자료로 활용하고자 하였다. 화북댐 상 하류에서 사후환경영향조사 기간(2004${\sim}$2008년) 중 측정된 수질항목 분석결과 현장에서 측정한 수온, 용존산소, 수소이온농도와 실내분석 항목인 부유물, 총대장균수의 경우 지점별로 다소 계절에 따른 변화를 나타냈지만 큰 차이를 보이지는 않았으나 유기물 및 영영염류 농도에 해당하는 생물학적 화학적 산소요구량, 엽록소, 질소, 인의 경우 지점별로 매우 큰 폭의 변화를 보였으며 상류에서 다소 높고 하류에서 낮은 경향을 보였다. 중금속 중 비소의 경우 2005년 6월 0.092 mg $L^{-1}$를 제외하고는 0.05 mg $L^{-1}$ 이하를 나타내어 하천수 수질환경기준 상 사람의 건강 보호 측면에서 규정한 0.05 mg $L^{-1}$ 이하의 범위 내에서 나타나는 것으로 확인되었다. 화북댐 상 하류에서 어류조사를 실시한 결과 총 7과 19종 10,263개체가 확인되었다. 조사된 어류 중 우점종은 하천 중 상류에 주로 서식하는 참갈겨니(62.5%)로 확인되었으며 아우점종은 버들치(10.6%)로 나타났다. 조사 구간인 위천 상류에서 확인된 19종 중 한국고유종은 긴몰개, 동사리, 쉬리 등 총 9종(47.4%)으로 나타났으며, 멸종위기야생동 식물 I급으로 지정된 얼룩새코미꾸리(Koreocobitis naktongensis)가 소수의 개체이지만 포획되었고, 외래도입종은 확인되지 않았다. 군집분석 결과 우점도 지수는 하류로 갈수록 감소한 반면에 다양도, 풍부도 지수는 하류로 갈수록 증가하였다. 우점종인 참갈겨니의 개체군 분석 결과, 길이-무게 상관관계식은 TW=0.000003$(TL)^{3.2603}$로서 매개변수 b값이 3.0보다 크게 나타나 개체군의 영양상태가 양호한 것으로 나타났다. 또한 유사시기에 다른 하천에서의 개체군들과 비교분석 결과 size별 평균 비대지수(CF)가 상대적으로 높은 값을 보여 화북댐 유역의 참갈겨니가 다른 지역보다 성장률이 높았다. 화북댐 상 하류에서 어류 조사 자료를 활용하여 하천건강성평가(IBI)를 적용한 결과, 대부분의 지점에서 양호(26${\sim}$35)에서 최적(36${\sim}$40)을 보였으며 지점 5에서 평균값이 가장 높게 나타냈다. 이러한 결과를 바탕으로 지속적인 모니터링을 실시하여 어류에 관한 환경영향평가와 하천건강성평가 등을 통한 화북댐 완공 후 상 하류 하천의 어류상 변화유무 및 환경영향을 파악하는데 도움이 될 것으로 사료된다.
