다중 플랫폼/센서를 활용한 연안 모니터링은 연안 해양환경 변화와 다양한 재해/재난을 높은 시공간 해상도로 정확하게 이해하기 위한 매우 중요한 수단이다. 하지만 다중 플랫폼과 센서를 복합적으로 이용한 통합 관측 연구는 미비한 실정이고, 통합 관측을 통한 효율성, 융합 한계성 등에 대해 평가된 바 없다. 본 연구에서는 다중 원격탐사 플랫폼/센서를 이용한 모의실험을 통해 통합 관측 방법을 제시하고, 그 효용성과 한계점을 진단하였다. 다양한 해양 재해, 재난을 모사하기 위하여 Rhodamine WT (RWT) 형광염료를 이용하여 통합 현장조사를 수행하였다. 2019년 9월 남해-여수 해역에 형광염료를 주입 후 위성(Kompsat-2/3/3A, Landsat-8 Operational Land Imager (OLI), Sentinel-3 Ocean and Land Colour Instrument (OLCI), GOCI), 무인항공기 (Mavic 2 pro, Inspire 2), 유인항공기 플랫폼을 이용하여 염료 패치의 분포와 이동을 탐지하였다. 형광염료 주입 초기 패치 규모는 2,600 ㎡ 이었고, 약 138분 후 62,000 ㎡ 규모까지 확산되었다. RWT 패치는 처음 주입된 지점으로 부터 점차 남서 방향으로 이동하였고, 이는 현장 모의 실험이 진행되는 동안 조위(고조: 7시 7분(286 cm), 저조: 13시 9분(73 cm))가 점차 낮아짐에 따라 조석이 남동 방향으로 흐르는 것과 유사하였다. 무인항공기 영상은 공간해상도와 시간해상도 측면에서 가장 높은 해상력을 보인 반면 탐지 영역이 가장 좁았다. 위성의 경우 탐지 영역은 넓었지만 재방문 주기가 길기 때문에 운용성 측면에서 타 플랫폼과 비교하여 다소 한계가 있었다. 또한 Sentinel-3 OLCI와 GOCI의 경우 분광해상도와 신호 대 잡음비(signal to noise ratio)가 가장 높았지만 소규모 형광염료 탐지에는 공간해상도 측면에서 제한적이었다. 유인항공기에 탑재된 초다분광 영상의 경우 분광해상도가 가장 높았지만 이 역시 운용성 측면에서 다소 제한적이었다. 다중 플랫폼 통합관측 연구를 통해 시간과 공간뿐만 아니라 분광 해상력 증가 향상을 확인 가능하였다. 향후 이 연구 결과가 연안 수치모델과 연계된다면 오염 물질의 이동확산 예측이 가능할 것으로 생각되고, 수치모델의 입력 및 검증 자료로 활용하여 모델 정확도 향상에 기여할 수 있을 것으로 기대된다.

Proliferation of Nocardia amarae cells in activated sludge has often been associated with the generation of nuisance foams. Despite intense research activities in recent years to examine the causes and control of Nocardia foaming in activated sludge, the foaming continued to persist throughout the activated sludge treatment plants in United States. In addition to causing various operational problems to treatment processes, the presence of Nocardia may have secondary effects on the fate of heavy metals that are not well known. For example, for treatment plants facing more stringent metal removal requirements, potential metal removal by Nocardia cells in foaming activated sludge would be a welcome secondary effect. In contrast, with new viosolid disposal regulations in place (Code o( Federal Regulation No. 503), higher concentration of metals in biosolids from foaming activated sludge could create management problems. The goal of this research was to investigate the metal sorption property of Nocardia amarae cells grown in batch reactors and in chemostat reactors. Specific surface area and metal sorption characteristics of N. amarae cells harvested at various growth stages were compared. Three metals examined in this study were copper, cadmium and nickel. Nocardia amarae strain (SRWTP isolate) used in this study was obtained from the University of California at Berkeley. The pure culture was grown in 4L batch reactor containing mineral salt medium with sodium acetate as the sole carbon source. In order to quantify the sorption of heavy metal ions to N amarae cell surfaces, cells from the batch reactor were harvested, washed, and suspended in 30mL centrifuge tubes. Metal sorption studies were conducted at pH 7.0 and ionlc strength of 10-2M. The sorption Isotherm showed that the cells harvested from the stationary and endogenous growth phase exhibited significantly higher metal sorption capacity than the cells from the exponential phase. The sequence of preferential uptake of metals by N. amarae cells was Cu>Cd>Ni. The specific surFace area of Nocardia cells was determined by a dye adsorption method. N.amarae cells growing at ewponential phase had significantly less specific surface area than that of stationary phase, indicating that the lower metal sorption capacity of Nocardia cells growing at exponential phase may be due to the lower specific surface area. The growth conditions of Nocardia cells in continuous culture affect their cell surface properties, thereby governing the adsorption capacity of heavy metal. The comparison of dye sorption isotherms for Nocardia cells growing at various growth rates revealed that the cell surface area increased with increasing sludge age, indicating that the cell surface area is highly dependent on the steady-state growth rate. The highest specific surface area of 199m21g was obtained from N.amarae cell harvested at 0.33 day-1 of growth rate. This result suggests that growth condition not only alters the structure of Nocardia cell wall but also affects the surface area, thus yielding more binding sites of metal removal. After reaching the steady-state condition at dilution rate, metal adsorption isotherms were used to determine the equilibrium distributions of metals between aqueous and Nocardia cell surfaces. The metal sorption capacity of Nocardia biomass harvested from 0.33 day-1 of growth rate was significantly higher than that of cells harvested from 0.5- and 1-day-1 operation, indicatng that N.amarae cells with a lower growth rate have higher sorpion capacity. This result was in close agreement with the trend observed from the batch study. To evaluate the effect of Nocardia cells on the metal binding capacity of activated sludge, specific surface area and metal sorption capacity of the mixture of Nocardia pure cultures and activated sludge biomass were determined by a series of batch experiments. The higher levels of Nocardia cells in the Nocardia-activated sludge samples resulted in the higher specific surface area, explaining the higher metal sorption sites by the mixed luquor samples containing greater amounts on Nocardia cells. The effect of Nocardia cells on the metal sorption capacity of activated sludge was evaluated by spiking an activated sludge sample with various amounts of pre culture Nocardia cells. The results of the Langmuir isotherm model fitted to the metal sorption by various mixtures of Nocardia and activated sludge indicated that the mixture containing higher Nocardia levels had higher metal adsorption capacity than the mixture containing lower Nocardia levels. At Nocardia levels above 100mg/g VSS, the metal sorption capacity of activate sludge increased proportionally with the amount of Noeardia cells present in the mixed liquor, indicating that the presence of Nocardia may increase the viosorption capacity of activated sludge.

Increasingly the institutional theory has been an important theoretical view of decision making process and IT adoption in many academic researches. This study used the institutional theory as a lens through which we can understand the factors that enable the effective appropriation of advanced information technology. It posits that mimetic, coercive, and normative pressures existing in an institutionalized environment could influence the participation of top managers or decision makers and the involvement of users toward an effective use of IT in their tasks. Since the introduction of IT, organizational members have been using IT in their daily tasks, creating and recreating rules and resources according to their own methods and needs. That is to say, the adaptation process of the IT and outcomes are different among organizations. The previous studies on a diverse use of IT refer to the appropriation of technology from the social technology view. Users appropriate IT through not only technology itself, but also in terms of how they use it or how they make the social practice in their use of it. In this study, the concepts of institutional pressure, appropriation, participation of decision makers, and involvement of users toward the appropriation are explored in the context of the appropriation of the mobile electronic medical record system (M-EMRS) in particularly a hospital setting. Based on the conceptual definition of institutional pressure, participation and involvement, operational measures are reconstructed. Furthermore, the concept of appropriation is measured in the aspect of three sub-constructs-consensus on appropriation, faithful appropriation, and attitude of use. Grounded in the relevant theories to appropriation of IT, we developed a research framework in which the effects of institutional pressure, participation and involvement on the appropriation of IT are analyzed. Within this theoretical framework, we formulated several hypotheses. We developed a second order institutional pressure and appropriation construct. After establishing its validity and reliability, we tested the hypotheses with empirical data from 101 users in 3 hospitals which had adopted and used the M-EMRS. We examined the mediating effect of the participation of decision makers and the involvement of users on the appropriation and empirically validated their relationships. The results show that the mimetic, coercive, and normative institutional pressure has an effect on the participation of decision makers and the involvement of users in the appropriation of IT while the participation of decision makers and the involvement of users have an effect on the appropriation of IT. The results also suggest that the institutional pressure and the participation of decision makers influence the involvement of users toward an appropriation of IT. Our results emphasize the mediating effect of the institutional pressure on the appropriation of IT. Namely, the higher degree of the participation of decision makers and the involvement of users, the more effective appropriation users will represent. These results provide strong support for institutional-based variables as predictors of appropriation. These findings also indicate that organizations should focus on the role of participation of decision makers and the involvement of users for the purpose of effective appropriation, and these are the practical implications of our study. The theoretical contribution of this study is lies in the integrated model of the effect of institutional pressure on the appropriation of IT. The results are consistent with the institutional theory and support previous studies on adaptive structuration theory.

As managing customer relationship gets more important, companies are strengthening information service using multi-channels to their customers as a part of their customer relationship management (CRM) initiatives. It means companies are now accepting such information services not as simple information -delivering tools, but as strategic initiatives for acquiring and maintaining customer loyalty. In this paper, we attempt to validate whether or not such various information services would impact on organizational performance in terms of CRM strategy. More specifically, our research objective is to answer the next three questions: first, how to construct the instruments to measure not information quality but information service quality?; second, which attributes of information service quality can influence corporate image and customer loyalty?; finally, does each information service type have unique characteristics compared with others in terms of influencing corporate image and customer loyalty? With respect to providing answers to those questions, the previous studies had been limited in that those studies failed to consider the variety of types of information service or restricted the quality of information service to information quality. An appropriate research model answering the above questions should consider the fact that most companies are utilizing multi channels for their information services, and include the recent strategic information service such as customer online community. Moreover, since corporate information service could be regarded as a type of products or services delivered to customer, it is necessary to adopt the criteria for assessing customer's perceived value when to measure the quality of information service. Therefore, considering both multi-channels and multi-traits may enable us to tell the detailed causal routes showing which quality attributes of which information service would affect corporate image and customer loyalty. As information service channels, we include not only homepage and DM (direct mail), which are the most frequently applied information service channels, but also online community, which is getting more strategic importance in recent years. With respect to information service quality, we abstract information quality, convenience of information service, and timeliness of information service through a wide range of relevant literature reviews. As our dependant variables, we consider corporate image and customer loyalty that both of them are the critical determinants of organizational performance, and also attempt to grasp the relationship between the two constructs. We conducted a huge online survey at the homepage of one of representative dairy companies in Korea, and gathered 367 valid samples from 407 customers. The reliability and validity of our measurements were tested by using Cronbach's alpha coefficient and principal factor analysis respectively, and seven hypotheses were tested through performing correlation test and multiple regression analysis. The results from data analysis demonstrated that timeliness and convenience of homepage have positive effects on both corporate image and customer loyalty. In terms of DM, its' information quality was represented to influence both corporate image and customer loyalty, but we found its' convenience have a positive effect only on corporate image. With respect to online community, we found its timeliness contribute significantly both to corporate image and customer loyalty. Finally, as we expected, corporate image was revealed to provide a great influence to customer loyalty. This paper provides several academic and practical implications. Firstly, we think our research reinforces CRM literatures by developing the instruments for measuring information service quality. The previous relevant studies have mainly depended on the measurements of information quality or service quality which were developed independently. Secondly, the fact that we conducted our research in a real situation may enable academics and practitioners to understand the effects of information services more clearly. Finally, since our study involved three different types of information service which are most frequently applied in recent years, the results from our study might provide operational guidelines to the companies that are delivering their customers information by multi-channel. In other words, since we found that, in terms of customer loyalty, the key areas would be different from each other according to the types of information services, our analysis would help to make decisions such as selecting strengthening points or allocating resources by information service channels.

자연은 잘 이용하면 자원이지만 잘못하면 재해가 되는 이중성을 갖는다. 작목선택, 작부체계, 비배관리에 기후, 토양, 물자원 등 환경정보 활용이 필수이며, 환경정보를 잘 활용하면 자원 활용도를 높여 수량과 품질 개선, 자연재해-에너지소비-오염 경감에 기여한다. 이러한 관계를 잘 알고 있기 때문에 어느 나라에서나 환경정보를 관리하는 부처가 존재한다. 시민생활의 안전과 행복을 위한 일기예보를 위시하여 산업, 교통, 국방을 위한 특수한 기상정보가 기상청에 의해 제공되나, 식량간보와 국토보전의 막중한 임무를 띤 농업분야의 특화된 기상정보는 없다. 이러한 현실인식을 바탕으로 농림부는 '전자기후도 기반 유역단위 농업기상 예보시스템' 사업을 2006년부터 4년간 경희대학교와 한국농림수산정보센터가 공동으로 수행하도록 지원하고 있다. 이 사업은 지난 수년간 크게 발전한 공간정보기술과 소기후추정기술을 이용하여, 1) 전국 840개 표준유역별로 30m 해상도의 전자기후도를 제작함으로써 농업기후자원을 필지단위로 정확히 파악하며, 2)기상청 디지털예보를 기반으로 농업기상예보 해상도를 영농규모 수준으로 높여서, 3) 적지적작, 적지적수 및 유역규모 생태계관리의 의사지원수단을 제공함을 목적으로 한다. 사업성과는 기상청-산림청-농촌진흥청 합동조직인 국가농업기상센터에서 활용하며 시군 자치단체는 한국농림수산정보센터의 기술이전에 의해 독자적인 시스템을 구축할 수 있다. 모든 정보는 초고속인터넷, 휴대폰, 위성통신 등을 통해 수요자에게 배포될 것이며, 이를 통해 우리의 농업기상서비스는 전통적인 발전단계를 뛰어넘어 단번에 선진국 수준에 도달하게 될 것으로 기대된다.공하는 과정에서도 관리를 철저히 하도록 해야 한다. 4. 뽕가지의 항산화능은 춘기, 추기 모두 뽕잎에 비해 상당히 낮은 항산화능을 보였으나, 항산화식품 소재로서 뽕가지를 이용할 경우 5월 하순${\sim}$6월 초순의 신소지를 이용하거나 껍질을 분리하여 이용하도록 한다.으며, 특히 5지점 (S5)은 나머지 4개 지점 (S1 ${\sim}$ S4)의 수질에 비해 뚜렷한 수질악화를 보였는데, 이는 제 5지점 부근의 공단과 분뇨처리시설로부터 유입된 폐수에 의한 점 오염원의 효과로 사료되었다. 어류의 지표종 특성에 따르면, 버들치 (Rhynchocypris oxycephalus), 갈겨니 (Zacco temmincki)와 같은 수질에 대해 민감한 어종은 상류(S1 ${\sim}$ S2)에서의 출현빈도가 하류지점에의 출현빈도에 비해 뚜렷하게 높게 나타나 수질 특성을 반영하는 것으로 나타났으며, 트로픽구조 측면에서 내성종 (Tolerant species)및 잡식성종(Omnivore species)이 하류로 갈수록 증가하는 경향을 보였다.대가 발달한다. 이것으로 볼 때 지열류량은 지질구조와 무관하지 않음을 파악할 수 있다. 특히 이러한 단층대 주변은 지열수의 순환이 깊은 심도까지 가능하므로 이러한 대류현상으로 지표부근까지 높은 지온 전달이 되어 나타나는 것으로 판단된다.의 안정된 방사성표지효율을 보였다. $^{99m}Tc$-transferrin을 이용한 감염영상을 성공적으로 얻을 수 있었으며, $^{67}Ga$-citrate 영상과 비교하여 더 빠른 시간

This study is aimed at investigating the compensatory education which was already implemented or is being implemented in the U.S.A. and Japan; and at studying the types of programs and their characteristics; and at sounding out the possibilities of the application of such programs in family and social conditions is Korea. In order to achieve the above mentioned objectives, the established items for the study are as follows: (1) Various types of early children's education (2) Programs of compensatory education for the disadvantaged Children (3) Head Start Program, Early Training Project and Montessori School (4) Integrated Preschool Programs (5) Day-Care Center for employed mothers We investigated the various compensatory education programs for the preschool children who are in economically, socially, culturally disadvantaged conditions. Head Start Programs were federally supported programs for preschool children and opened as summer programs in 1965 for the first time. The purpose of Head Start has been to give preschool children the kinds of experiences they need in preparation for school. The Head Start children were found to be significantly better prepared for school than the normal children. However, after six to eight months, their initial advantages had virtually. disappeared and then the simple problem with Head Start and other such programs was that little long-term good could be evidenced unless the high quality educational environment was maintained. Therefore, to solve this problem, three other programs were funded as part of the overall Head Start. These three programs are the Parent-Child Center, Home Start, and the Child and Family Resources Program. The Early Training Project for disadvantaged children was implemented by Klaus and Gray of Peabody College in 1962. The program was a field research study concerned with the development and testing over time of procedures for improving the educability of young children from low income homes. Its major concern was to study whether it was possible to offset the progressive retardation observed in the public schooling careers of children, living in deprived circumstances. Children, who were trained through the Early Training Project were superior to control groups in the test of IQ and vocabulary as well as linguistic abilities, and preparation for reading. This project showed the possibilities which could prevent preschool children from being disadvantaged socially, culturally and mentally. In 1907, Montessori School was established by Maria Montessori in Italy and her school program has been introduced at present to several countries in the world as one compensatory educations. She first began her experimental methods with retarded children, followed by disadvantaged children from the tenements of Rome. The Montessori approach futures a prepared environment and carefully designed, self-correcting materials. The Montessori curriculum presents tastes that feature sequence, order, and regularity, in addition to those that develop motor and sensory skills. She was interested in children's intellectual development and in developing good work habits. One of the latest developed programs for disadvantaged children is "Integrated Preschool Program" which has successfully integrated handicapped and nonhandicapped children. Several studies have showed that handicapped children in integrated school environments are accepted by and interact with their nonhandicapped peers. In fact, this program provides a number of potential, and perhaps opportunities for nonhandicapped children to serve as valuable resources in fostering the development of their handicapped peers. Next we turn to Japanese programs which are divided into two different types. One is Day-Care Center which was established by Child Welfare Law and the other is kindergarten organized by School Education Law. The kindergarten opened in 1876 and it has been part of school systems since 1947 by the implementation of education law, and the Day-Care Center which started in 1890 for the employed mothers. was changed into Day-Nursery by the enactment of child welfare law in 1947. The laws and operational regulations for the Day-Nursery were set up and were put in effect by the establishment standard acts of children welfare facilities, and the Day-Nursery has been operated in various types by the increasing demand, chiefly because of the socio-economical changes of family structures in both urban and suburban areas. Nursery education for physically and mentally disadvantaged children is for those who are blind, deaf and dumb, mentally retarded; physically disadvantaged by accidents or diseases. Montessori education in Japan was started in 1968 and many research groups for studying Montessori were organized. In 1977, Montessori remedial education society was also organized in which they started a number of studies; a study for developing materials; in-service training for the remedial education; and seminars and lectures, etc It is strongly suggested that we study the early educations that are being implemented in Japan and a variety of compensatory educations that were already implemented in the U.S.A. and modify them for the organization of our own model and properly accommodate them to our social needs.

국내 원자력 방사선 산업의 높은 성장과 전문 인력 수요의 증가는 기술 발전 단계관점에서 기술 공학자 혹은 중간기술자의 수요 확대를 가져왔다. 그러나 원자력 방사선 기술의 발전과 이용에 비해 전문인력 양성 교육기관은 빈약한 실정이다. 산업체에서 가장 필요로 하는 인력은 초중급 기술인력으로 이들을 양성할 교육기관이 필요하며 이들의 교육 수요를 만족시켜줄 가장 유리한 교육기관은 전문대학이라 하겠다. 따라서 현재 의료분야로 편중된 우리나라의 전문대학방사선과 교육과정을 산업체에서도 필요로 하는 교육과정을 개발하고자 한다. 연구개발의 내용과 그 범위는 크게 4가지로 구분하여 연구를 수행하였다. 첫 번째, 교육과정 시행의 대상인 방사선 산업체 관련 인력환경 기초 조사를 시행하였으며, 이를 위해 세부 시행 업무로서 국내의 방사선 산업체 종사자, 전문대학 방사선과 재학생과 교수를 대상으로 설문조사 및 분석을 하였다. 두 번째, 교육과정 개발에 필요한 기초 자료로서 국내외 방사선 관련 대학들의 사례를 통해 교육과정을 분석하였다. 또 이를 위해 국내, 일본, 미국의 방사선 관련 대학의 교육과정을 조사 및 분석하였다. 세 번째, 방사선 산업에 필요한 기초 과학 교과목과 방사선 전공 교과목을 개발하였다. 이 과정에서는 미국과 한국의 공학교육 인증원에서 제안하고 있는 원자력, 방사선 관련 교육 프로그램 지침을 참고로 하였다. 네 번째로 정규 교육과정에 필요한 교과목 즉 선택형 교과목을 개발하였는데, 여기에는 교과목 운영에 필요한 교육과정 개발과 정규 교육과정 이외의 심화과정 및 부전공제 운영 모델의 개발이 포함되었다. 연구의 핵심 결과는 방사선 산업체 업무 분야에 적합한 선택형 세부 교육과정을 제안하였는데, 각 대학의 특성과 교육 목표에 따라 달라질 수 있다. 첫 번째는 업무분야별 세부교육과정으로, 방사선 이용분야에 적합한 교과목과 방사선 안전관리 분야에 적합한 교과목을, 두 번째로 업체 유형별 세부교육과정으로 제조업체에 필요한 교과목, 비파괴검사업체에서 필요한 교과목, 판매기관에서 필요한 교과목, 그리고 연구소에서 필요한 교과목을 선정하였다. 또한 이러한 교과목을 시행하기 위하여 교과과정 2가지 운영 모델을 제안하였는데, 첫째는 현재 전문대학 방사선과 3년 과정에서 의료분야 전공과 산업분야전공 별로 전공제를 실시하는 방법과 둘째로, 전문대학을 졸업 후 심화과정(1년 과정)에서 산업방사선을 전공하도록 하는 방법이다. 운영모델을 좀더 효과적으로 운영하기 위해서는 보다 심도 있는 학제 연구와 더불어 교재의 개발이 전제되어야 하며, 교과운영에 필요한 교수인력, 실습공간, 기자재 등의 재정의 확보 역시 해결되어야 할 문제이다.

Objectives Lumbar herniated intervertebral disc (L-HIVD) is common disease in which Western-Korean collaborative treatment is performed in Korea. This study aimed to analyze Western-Korean collaborative treatment utilization of Korean patients with L-HIVD using Health Insurance Review & Assessment Service's Patients Sample Data. Methods This study used the Health Insurance Review & Assessment Service-National Patient Sample (HIRA-NPS) in 2018. Claim data of L-HIVD patients were extracted. The claim data were rebuilt with the operational concept of 'episode of care' and divided into Korean medicine episode group (KM), Western medicine episode group (WM) and collaborative treatment episode group (CT). General characteristics, medical expenses and healthcare utilization were analyzed. In addition, the difference of average visit day and average medical expenses between non-collaborative group (KM plus WM) and CT were analyzed by the propensity score matching method. Results A Total of 64,333 patients and 365,745 claims were extracted. The number of episodes of WM, KM and CT was 69,383 (92.97%), 3,903 (5.23%), and 1,341 (1.80%) respectively. The frequency of collaborative treatment episode was higher in women and the age of 50s. The most frequently described treatment in CT was acupuncture therapy. As a result of the propensity score matching, the number of visit days and medical expenses in the collaborative treatment group was higher than in the non-collaborative group. Conclusions The analysis of healthcare utilization of Korean-Western collaborative treatment may be used as basic data for establishing medical policies and systematic collaborative treatment model in the future.

본 연구는 최근 남중국해와 동중국해를 둘러싼 해양 갈등에서 중국의 주요 해양안보전략 중 하나로 사용되기 시작한 "회색지대전략"의 전반적인 메커니즘을 경험적으로 분석하고, 그로 인한 남중국해 및 동중국해 분쟁 양상을 비교하는 데에 그 목적을 둔다. 이를 위해 필자는 중국의 회색지대전략에 관한 두 가지 가설들을 세워 남중국해와 동중국해 분쟁에서 중국의 회색지대전략이 어떻게 '구사'되어 왔고 '구성'되어 있는지, 상대국은 어떤 방식으로 그것에 대응하는지 살펴보고, 그로 말미암아 각 분쟁들의 양상은 어떤 유사점과 차이점을 보이는지 밝혀냈다. 필자가 이 연구에서 수립한 가설들은 첫 째, "중국이 활용하는 해양 회색지대전략은 주요 분쟁 지역인 남중국해와 동중국해에서 각기 다른 수행 구조를 보인다는 것"이다. 두 번째는, "이에 따라 남중국해와 동중국해에서 벌어지는 분쟁의 양상 역시 차이를 보인다는 것"이다. 이를 논증하기 위해 필자는 중국의 회색지대전략 메커니즘을 크게 차례대로 1) 분쟁 추이와 전략 수행의 빈도, 2) 전략의 유형과 강도, 3) 전략 수행의 행위자, 4) 상대국의 대응 방식으로 다차원적인 구분을 시도하고, 양적 모델링을 바탕으로 이에 관련 데이터를 수집했다. 이후, 2010년부터 2020년 06월에 이르는 약 10년 가량의 데이터(중국의 회색지대전략 사용과 분쟁 동향 등)를 가공하고, 직접 연구 모형을 설계해 회색지대전략에 대한 새로운 범주화와 조작적 정의를 시도했다. 이를 바탕으로 필자는 중국이 활용하는 회색지대전략의 포괄적인 메커니즘들과 남중국해와 동중국해의 분쟁 양상도 성공적으로 비교해 최종적으로 모든 가설을 검증할 수 있었다. 결론 부분에서는 검증된 결과를 재차 정리하고, 중국의 회색지대전략으로 인해 비롯될 수 있는 동아시아 역내의 안보 취약성을 극복해 나가야 함을 강조하는 것으로 마무리했다. 본 연구는 지금까지 한 번도 시도되지 않았던 연구로서 중국의 회색지대전략이 수행되는 구조를 밝히고, 이것과 해양 분쟁 양상 간의 상관관계를 양적 방법론을 이용해 규명했다는 데에 큰 의의가 있으리라 생각된다.
