To survive in the global competitive environment, enterprise should be able to solve various problems and find the optimal solution effectively. The big-data is being perceived as a tool for solving enterprise problems effectively and improve competitiveness with its' various problem solving and advanced predictive capabilities. Due to its remarkable performance, the implementation of big data systems has been increased through many enterprises around the world. Currently the big-data is called the 'crude oil' of the 21st century and is expected to provide competitive superiority. The reason why the big data is in the limelight is because while the conventional IT technology has been falling behind much in its possibility level, the big data has gone beyond the technological possibility and has the advantage of being utilized to create new values such as business optimization and new business creation through analysis of big data. Since the big data has been introduced too hastily without considering the strategic value deduction and achievement obtained through the big data, however, there are difficulties in the strategic value deduction and data utilization that can be gained through big data. According to the survey result of 1,800 IT professionals from 18 countries world wide, the percentage of the corporation where the big data is being utilized well was only 28%, and many of them responded that they are having difficulties in strategic value deduction and operation through big data. The strategic value should be deducted and environment phases like corporate internal and external related regulations and systems should be considered in order to introduce big data, but these factors were not well being reflected. The cause of the failure turned out to be that the big data was introduced by way of the IT trend and surrounding environment, but it was introduced hastily in the situation where the introduction condition was not well arranged. The strategic value which can be obtained through big data should be clearly comprehended and systematic environment analysis is very important about applicability in order to introduce successful big data, but since the corporations are considering only partial achievements and technological phases that can be obtained through big data, the successful introduction is not being made. Previous study shows that most of big data researches are focused on big data concept, cases, and practical suggestions without empirical study. The purpose of this study is provide the theoretically and practically useful implementation framework and strategies of big data systems with conducting comprehensive literature review, finding influencing factors for successful big data systems implementation, and analysing empirical models. To do this, the elements which can affect the introduction intention of big data were deducted by reviewing the information system's successful factors, strategic value perception factors, considering factors for the information system introduction environment and big data related literature in order to comprehend the effect factors when the corporations introduce big data and structured questionnaire was developed. After that, the questionnaire and the statistical analysis were performed with the people in charge of the big data inside the corporations as objects. According to the statistical analysis, it was shown that the strategic value perception factor and the inside-industry environmental factors affected positively the introduction intention of big data. The theoretical, practical and political implications deducted from the study result is as follows. The frist theoretical implication is that this study has proposed theoretically effect factors which affect the introduction intention of big data by reviewing the strategic value perception and environmental factors and big data related precedent studies and proposed the variables and measurement items which were analyzed empirically and verified. This study has meaning in that it has measured the influence of each variable on the introduction intention by verifying the relationship between the independent variables and the dependent variables through structural equation model. Second, this study has defined the independent variable(strategic value perception, environment), dependent variable(introduction intention) and regulatory variable(type of business and corporate size) about big data introduction intention and has arranged theoretical base in studying big data related field empirically afterwards by developing measurement items which has obtained credibility and validity. Third, by verifying the strategic value perception factors and the significance about environmental factors proposed in the conventional precedent studies, this study will be able to give aid to the afterwards empirical study about effect factors on big data introduction. The operational implications are as follows. First, this study has arranged the empirical study base about big data field by investigating the cause and effect relationship about the influence of the strategic value perception factor and environmental factor on the introduction intention and proposing the measurement items which has obtained the justice, credibility and validity etc. Second, this study has proposed the study result that the strategic value perception factor affects positively the big data introduction intention and it has meaning in that the importance of the strategic value perception has been presented. Third, the study has proposed that the corporation which introduces big data should consider the big data introduction through precise analysis about industry's internal environment. Fourth, this study has proposed the point that the size and type of business of the corresponding corporation should be considered in introducing the big data by presenting the difference of the effect factors of big data introduction depending on the size and type of business of the corporation. The political implications are as follows. First, variety of utilization of big data is needed. The strategic value that big data has can be accessed in various ways in the product, service field, productivity field, decision making field etc and can be utilized in all the business fields based on that, but the parts that main domestic corporations are considering are limited to some parts of the products and service fields. Accordingly, in introducing big data, reviewing the phase about utilization in detail and design the big data system in a form which can maximize the utilization rate will be necessary. Second, the study is proposing the burden of the cost of the system introduction, difficulty in utilization in the system and lack of credibility in the supply corporations etc in the big data introduction phase by corporations. Since the world IT corporations are predominating the big data market, the big data introduction of domestic corporations can not but to be dependent on the foreign corporations. When considering that fact, that our country does not have global IT corporations even though it is world powerful IT country, the big data can be thought to be the chance to rear world level corporations. Accordingly, the government shall need to rear star corporations through active political support. Third, the corporations' internal and external professional manpower for the big data introduction and operation lacks. Big data is a system where how valuable data can be deducted utilizing data is more important than the system construction itself. For this, talent who are equipped with academic knowledge and experience in various fields like IT, statistics, strategy and management etc and manpower training should be implemented through systematic education for these talents. This study has arranged theoretical base for empirical studies about big data related fields by comprehending the main variables which affect the big data introduction intention and verifying them and is expected to be able to propose useful guidelines for the corporations and policy developers who are considering big data implementationby analyzing empirically that theoretical base.

The interplay between hedonic and utilitarian attributes has assumed special significance in recent years; it has been proposed that consumption offerings should be viewed as experiences that stimulate both cognitions and feelings rather than as mere products or services. This research builds on previous work on hedonic versus utilitarian benefits, regulatory focus theory, customer satisfaction to address two question: (1) Is the shopping goal at the point of purchase different from the shopping value? and (2) Is the customer loyalty after the use different from the shopping value and shopping goal? We surveyed 345 peoples those who have bought the electronic-goods within 6 months. This research dealt with the shopping value which is consisted of 2 types, hedonic and utilitarian. Those who pursue the hedonic shopping value may prefer the pleasure of purchasing experience to the product itself. They tend to prefer atmosphere, arousal of the shopping experience. Consistent with previous research, we use the term "hedonic" to refer to their aesthetic, experiential and enjoyment-related value. On the contrary, Those who pursue the utilitarian shopping value may prefer the reasonable buying. It may be more functional. Consistent with previous research, we use the term "utilitarian" to refer to the functional, instrumental, and practical value of consumption offerings. Holbrook(1999) notes that consumer value is an experience that results from the consumption of such benefits. In the context of cell phones for example, the phone's battery life and sound volume are utilitarian benefits, whereas aesthetic appeal from its shape and color are hedonic benefits. Likewise, in the case of a car, fuel economics and safety are utilitarian benefits whereas the sunroof and the luxurious interior are hedonic benefits. The shopping goals are consisted of the promotion focus goal and the prevention focus goal, based on the self-regulatory focus theory. The promotion focus is characterized into focusing ideal self because they are oriented to wishes and vision. The promotion focused individuals are tend to be more risk taking. They are more sensitive to hope and achievement. On the contrary, the prevention focused individuals are characterized into focusing the responsibilities because they are oriented to safety. The prevention focused individuals are tend to be more risk avoiding. We wanted to test the relation among the shopping value, shopping goal and customer loyalty. Customers show the positive or negative feelings comparing with the expectation level which customers have at the point of the purchase. If the result were bigger than the expectation, customers may feel positive feeling such as delight or satisfaction and they would want to share their feelings with other people. And they want to buy those products again in the future time. There is converging evidence that the types of goals consumers expect to be fulfilled by the utilitarian dimension of a product are different from those they seek from the hedonic dimension (Chernev 2004). Specifically, whereas consumers expect the fulfillment of product prevention goals on the utilitarian dimension, they expect the fulfillment of promotion goals on the hedonic dimension (Chernev 2004; Chitturi, Raghunathan, and Majahan 2007; Higgins 1997, 2001) According to the regulatory focus theory, prevention goals are those that ought to be met. Fulfillment of prevention goals in the context of product consumption eliminates or significantly reduces the probability of a painful experience, thus making consumers experience emotions that result from fulfillment of prevention goals such as confidence and securities. On the contrary, fulfillment of promotion goals are those that a person aspires to meet, such as "looking cool" or "being sophisticated." Fulfillment of promotion goals in the context of product consumption significantly increases the probability of a pleasurable experience, thus enabling consumers to experience emotions that result from the fulfillment of promotion goals. The proposed conceptual framework captures that the relationships among hedonic versus utilitarian shopping values and promotion versus prevention shopping goals respectively. An analysis of the consequence of the fulfillment and frustration of utilitarian and hedonic value is theoretically worthwhile. It is also substantively relevant because it helps predict post-consumption behavior such as the promotion versus prevention shopping goals orientation. Because our primary goal is to understand how the post consumption feelings influence the variable customer loyalty: word of mouth (Jacoby and Chestnut 1978). This research result is that the utilitarian shopping value gives the positive influence to both of the promotion and prevention goal. However the influence to the prevention goal is stronger. On the contrary, hedonic shopping value gives influence to the promotion focus goal only. Additionally, both of the promotion and prevention goal show the positive relation with customer loyalty. However, the positive relation with promotion goal and customer loyalty is much stronger. The promotion focus goal gives the influence to the customer loyalty. On the contrary, the prevention focus goal relates at the low level of relation with customer loyalty than that of the promotion goal. It could be explained that it is apt to get framed the compliment of people into 'gain-non gain' situation. As the result, for those who have the promotion focus are motivated to deliver their own feeling to other people eagerly. Conversely the prevention focused individual are more sensitive to the 'loss-non loss' situation. The research result is consistent with pre-existent researches. There is a conceptual parallel between necessities-needs-utilitarian benefits and luxuries-wants-hedonic benefits (Chernev 2004; Chitturi, Raghunathan and Majaha 2007; Higginns 1997; Kivetz and Simonson 2002b). In addition, Maslow's hierarchy of needs and the precedence principle contends luxuries-wants-hedonic benefits higher than necessities-needs-utilitarian benefits. Chitturi, Raghunathan and Majaha (2007) show that consumers are focused more on the utilitarian benefits than on the hedonic benefits of a product until their minimum expectation of fulfilling prevention goals are met. Furthermore, a utilitarian benefit is a promise of a certain level of functionality by the manufacturer or the retailer. When the promise is not fulfilled, customers blame the retailer and/or the manufacturer. When negative feelings are attributable to an entity, customers feel angry. However in the case of hedonic benefit, the customer, not the manufacturer, determines at the time of purchase whether the product is stylish and attractive. Under such circumstances, customers are more likely to blame themselves than the manufacturer if their friends do not find the product stylish and attractive. Therefore, not meeting minimum utilitarian expectations of functionality generates a much more intense negative feelings, such as anger than a less intense feeling such as disappointment or dissatisfactions. The additional multi group analysis of this research shows the same result. Those who are unsatisfactory customers who have the prevention focused goal shows higher relation with WOM, comparing with satisfactory customers. The research findings in this article could have significant implication for the personal selling fields to increase the effectiveness and the efficiency of the sales such that they can develop the sales presentation strategy for the customers. For those who are the hedonic customers may be apt to show more interest to the promotion goal. Therefore it may work to strengthen the design, style or new technology of the products to the hedonic customers. On the contrary for the utilitarian customers, it may work to strengthen the price competitiveness. On the basis of the result from our studies, we demonstrated a correspondence among hedonic versus utilitarian and promotion versus prevention goal, WOM. Similarly, we also found evidence of the moderator effects of satisfaction after use, between the prevention goal and WOM. Even though the prevention goal has the low level of relation to WOM, those who are not satisfied show higher relation to WOM. The relation between the prevention goal and WOM is significantly different according to the satisfaction versus unsatisfaction. In addition, improving the promotion emotions of cheerfulness and excitement and the prevention emotion of confidence and security will further improve customer loyalty. A related potential further research could be to examine whether hedonic versus utilitarian, promotion versus prevention goals improve customer loyalty for services as well. Under the budget and time constraints, designers and managers are often compelling to choose among various attributes. If there is no budget or time constraints, perhaps the best solution is to maximize both hedonic and utilitarian dimension of benefits. However, they have to make trad-off process between various attributes. For the designers and managers have to keep in mind that without hedonic benefit satisfaction of the product it may hard to lead the customers to the customer loyalty.

The objective of this paper is to think about what structural reforms of the Korean government S&T development management system might be. Korean society is currently experiencing a drastic socio-economic transformation. The results of this transformation should be reflected on the determining process of the directions and breadths of structural reforms of government S&T development management system. Because the government system design will be based on the premises of socio-economic conditions under which administrative activities perform and also this socio-economic changes can influence on changes of the premises of government management system design. Moreover, S&T development management system is a subsystem of government system so that the directions of structural reform of those subsystems should be considered in the broad framework changes in the development management system of the government. For the last forty years, the Korean government S&T development management system has been based on the premises including transformation from an agrarian society to an industrial society, authoritarianism and centrally controlled institutions, and exteremely small portions of private investments for science and thechonology R & D of the total. Recently, however, the premises of Korean government S&T development management system have rapidly changed. the characteristics of these changes are including tranformation from an industrial society to a knowledge and information intensive society, globalization, localization, and relatively large portion of private investments for science and technology R & C of the total. The basis of government reforms in Korea was the realization of the performances and values through the enhancement of national competitive capacity, attainment of lean government, decentralization and autonomy. However, the Korean government has attached a symbolic value of strategic organizations representing strong policy intentions of government for the science and technology based development. Most problems associated with the Korean government S&T development management system have grown worse during 1990s. Many people perceive that considerable part of this problem was generated because the government could not properly adapt itself to new administrative environment and the paradigm shift in its role. First of all, the Korean government S&T development management system as a whole failed to develop an integrated vision under which processes in formulating science and thechology development goals and developing consistent government plans concerning science and technology development are guided. Second, most of the local governments have little organizational capacity and manpowers to handle localized activities to promote science and technology in their regions. Third, the measure to coordinate and set priorities to invest resources for the development of science and technology was not effective. Fourth, the Most has been losing its reputation as the symbol of ideological commitment of the top policy maker to promote science and technology. Various ideas to reform government S&T development management system have been suggested recently. Most frequently cited ideas are as follow : (ⅰ)strengthen the functions of MoST by supplementing the strong incentive and regulatory measures; (ⅱ)create a new Ministry of Education, Science & Technology and Research by merging the Ministry of Education and the MoST; (ⅲ)create a new Ministry of Science & Technology and Industry ; and(ⅳ)create a National Science and Technology Policy Council under the chairmanship of the President. Four alternatives suggested have been widely discussed among the interested parties and they each have merits as well as weaknesses. The first alternative could be seen as an alternative which cannot resolve current conflicts among various ministries concerning priority setting and resource allocation. However, this alternatives can be seen as a way of showing the top policymaker's strong intention to emphasize science and technology based development. Second alternative is giving a strategic to emphasize on the training and supplying qualified manpower to meet knowledge and information intensive future society. This alternative is considered to be consistent with the new administrative paradigm emphasizing lean government and decentralization. However, opponents are worrying about the linkages and cooperative research between university and industry could be weakening. The third alternative has been adopted mostly in nations which have strong basic science research but weak industrial innovation traditions. Main weakness of this alternative for Korea is that Korean science and technology development system has no strong basic science and technology research traditions. The fourth alternative is consistent with new administrative paradigms and government reform bases. However, opponents to this alternative are worried that the intensive development of science and technology because of Korea's low potential research capabilities in science and technology development. Considerning the present Korean socio-economic situation which demands highly qualified human resources and development strategies which emphasizes the accumulations of knowledge-based stocks, I would like to suggest the route of creating a new Ministry of Education, Science & Technology and Research by intergrating education administration functions and science & technology development function into one ministry.

"Plant genetic resources for food and agriculture" means any genetic material of plant origin of actual or potential value for food and agriculture. "Genetic material" means any material of plant origin, including reproductive and vegetative propagating material, containing functional units of heredity. (Internal Treaty on Plant Genetic Resources for Food and Agriculture, ITPGRFA). The "Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization (ABS) to the Convention on Biological Diversity (shortly Nagoya Protocol)" is a supplementary agreement to the Convention on Biological Diversity. It provides a transparent legal framework for the effective implementation of one of the three objectives of the CBD: the fair and equitable sharing of benefits arising out of the utilization of genetic resources. The Nagoya Protocol on ABS was adopted on 29 October 2010 in Nagoya, Japan and entered into force on 12 October 2014, 90 days after the deposit of the fiftieth instrument of ratification. Its objective is the fair and equitable sharing of benefits arising from the utilization of genetic resources, thereby contributing to the conservation and sustainable use of biodiversity. The Nagoya Protocol will create greater legal certainty and transparency for both providers and users of genetic resources by; (a) Establishing more predictable conditions for access to genetic resources and (b) Helping to ensure benefit-sharing when genetic resources leave the country providing the genetic resources. By helping to ensure benefit-sharing, the Nagoya Protocol creates incentives to conserve and sustainably use genetic resources, and therefore enhances the contribution of biodiversity to development and human well-being. The Nagoya Protocol's success will require effective implementation at the domestic level. A range of tools and mechanisms provided by the Nagoya Protocol will assist contracting Parties including; (a) Establishing national focal points (NFPs) and competent national authorities (CNAs) to serve as contact points for information, grant access or cooperate on issues of compliance, (b) An Access and Benefit-sharing Clearing-House to share information, such as domestic regulatory ABS requirements or information on NFPs and CNAs, (c) Capacity-building to support key aspects of implementation. Based on a country's self-assessment of national needs and priorities, this can include capacity to develop domestic ABS legislation to implement the Nagoya Protocol, to negotiate MAT and to develop in-country research capability and institutions, (d) Awareness-raising, (e) Technology Transfer, (f) Targeted financial support for capacity-building and development initiatives through the Nagoya Protocol's financial mechanism, the Global Environment Facility (GEF) (Nagoya Protocol). The Rural Development Administration (RDA) leading to conduct management agricultural genetic resources following the 'ACT ON THE PRESERVATION, MANAGEMENT AND USE OF AGRO-FISHERY BIO-RESOURCES' established on 2007. According to $2^{nd}$ clause of Article 14 (Designation, Operation, etc. of Agencies Responsible for Agro-Fishery Bioresources) of the act, the duties endowed are, (a) Matters concerning securing, preservation, management, and use of agro-fishery bioresources; (b) Establishment of an integrated information system for agro-fishery bioresources; (c) Matters concerning medium and long-term preservation of, and research on, agro-fishery bioresources; (d) Matters concerning international cooperation for agro-fishery bioresources and other relevant matters. As the result the RDA manage about 246,000 accessions of plant genetic resources under the national management system at the end of 2016.

본 논문은 영국철도민영화의 현황과 과제를 서술한 논문으로 특히 2000년 Hatfield사고 이후의 내용을 중심으로 다루었다. 그간의 국내외 논문들은 최근의 변화 특히 2000년 발생한 대형철도사고인 Hatfield사고 이후의 급격한 변화를 설명하지 못했고, 방법론에서 민영화추진의 가장 기본적인 틀인 1992년 백서를 중심으로 설명하지 않았으며. 국철 시대의 장기적인 변화 자료와 민영화 이후 성과의 직접적인 비교가 다소 미흡하였다. 이에 본 논문에서는 그간의 민영화 추진과정과 최근의 급격한 변화과정을 살펴보고 장기간의 국철시대 자료와 비교하여 민영화내용을 검토해 보았으며 특히 Hatfield사고 이후의 변화내용을 중점적으로 살펴보았다. 본 논문에서는 영국철도는 민영화 추진과정에 서 국영철도에서의 문제점을 의식하여 독점을 방지하고 경쟁을 지나치게 강조한 결과 관리체계가 과도하게 중복된 면이 있었고, 특히 계획 기능과 인프라 기능에 대한 정책내용이 미흡했다는 점을 지적했다. 이러한 문제점에 대하여 2000년 이후의 조직의 변하는 다음과 같다 공적기관으로서의 네트워크레일의 탄생과 전략철도청(SRA)의 폐지, 건강 안전 청(HSE)로 부터 ORR과 네트워크레일로의 안전기능 이관 등으로 철도인프라의 관리에 대해 정부책임이 강화되었으며. 중복적인 규제체계도 단순화되었고 안전에 대해 운영자 책임도 강화되었다. 그리고 철도투자계획도 정부가 직접 담당하도록 하였다. 영국철도민영화의 그간의 과정을 종합적보면 2005년 말 시점에서 수송량은 증가하였고, 수입향상과 인력 감축 등으로 비용은 감소하여 경영성적은 향상하였고 정부 보조금 또한 감소하였다. 그러나 소비자입장에서의 신뢰성과 정시성 그리고 안전성 면에서 아직도 확실한 성과가 나타나지 않고 있으며 특히 Hatfield 사고 이후에 정시성과 신뢰성 저하 그리고 비용증가의 문제는 앞으로 해결되어야 할 과제로 지적되었다. 미치는 것으로 확인되었다. 대구${\sim}$대전 구간의 통행수단 선택모형의 추정결과를 보면 차외시간, 차외비용, 차내시간 통행빈도, 나이(51세 이상 제외), 직업, 가구 전체의 월평균 소득이 지역 간 통행수단 선택에 중요한 영향을 미친다는 사실을 확인할 수 있었다.을 길게 하더라도 치료에 필요한 적정 수준의 체내 요오드량 감소를 달성하기 어려울 것으로 판단된다. 그러나 1주간 엄격한 저요오드식이를 시행한 군에서도 체내 요오드량의 감소가 충분히 감소하는 비율이 여전히 낮기 때문에 엄격한 저요오드식이 방법을 2주간 시행하는 것이 더바람직하리라 기대된다.. 시험관 섭취율에서 $[^{18}F]$FLT는 시간이 지남에 따라 증가하는 양상을 보였고 생체분포 실험에서 주사 후 120분에서 tumor/blood, tumor/muscle, tumor/brain의 비율은 $1.61{\pm}0.34,\;1.70{pm}0.30,\;9.33{\pm}2.22$를 나타내었다. 또한, 양전자방출단층촬영 결과 종양에 국소화된 영상을 얻었다. 결론: $[^{18}F]$FLT의 종양세포 섭취는 정상 뇌에 비해 월등히 높게 나타났으며, 양전자방출단층 촬영 결과는 뇌종양 진단을 위한 방사성의약품으로 유용하게 이용될 수 있을 것으로 기대된다.$[^{11}C]raclopride$의 수용체 결합능의 변화는 미상핵에서 4.7%, 전피각에서 4.0%, 복측 선조체에서 7.8% 의 감소를 보여 흡연에 의한 선조체내 도파민 유리를 정량화 하였다. 특히 선조체에서의 도파민 유리에 의한 수용체 결합능의 감소는 흡연에 의한 혈중 니코틴의 축적 농도와 양의 상관관계를 보였다(rho=0.9, p=0.04). 결론: $[^{11}C]raclopride$ PET을 이용하여 비흡연 정상인에서 흡연에 의한

항공법에서 항공기를 규정함으로써 제도적 안전확보를 위한 규제체계를 확보하고 있다. 최신기술의 개발에 따라 항공기의 종류가 다양화되었고, 첨단화되어 새로운 형태의 항공기가 운영되고 있다. 특히 경량항공기 및 초경량비행장치는 자이로플레인, 무인비행장치 등 새로운 기술에 따른 신 개념의 항공기가 도입되고 있어, 이를 운영시 항공기의 기준에 따라 규제할 수 없는 경우가 발생한다. 경량항공기 및 초경량항공기는 다양하게 조립 및 개조할 수 있어 항공업무에 종사하는 사람에 대해 안전관리 등을 수행할 수 있는 법적 근거가 마련되었다. 새로 도입된 항공기의 분류에 따라 가장 큰 변화는 경량항공기 개념의 도입이다. 국내에서는 경량항공기들이 다양하게 도입되어 운영되고 있으나, 이들의 항공기 범위가 명확하지 않아 항공법 규정 내에서 안전 확보에 어려움이 있었다. 본 연구에서는 항공기의 분류에 대한 국제적인 시각과 우리나라의 시각의 차이점에 대하여 살펴보았다. 경량항공기의 경우 국제적으로 항공기에 포함 되지만, 우리나라에서는 항공기에 포함되지 않으며, 동력비행장치의 범위의 하나인 경량항공기로 존재하고 있다. 경량항공기 범위에서 최대수평비행속도에 대한 제한은 국제적인 추세나, 제작 또는 성능이 우수한 비행기를 사용할 수 있는 국민의 권리에 대한 제한이며, 경량항공기제도 도입 취지인 대국민 안정성확보 및 경량항공 산업 활성화에 걸림돌로 작용하고 있다. 차후 항공법규 개정시 경량항공기의 범위 관련되는 조항에서 최대수평비행속도를 제한하는 내용 삭제는 경량항공기 제도 도입 취지에 적합한 것으로 판단된다. 경량항공기 제도 도입의 목적은 기존에 초경량비행장치 범주를 초과하는 초경량비행장치의 안전을 확보하기 위해 설정된 법 규정이며, 국내외 발전하는 항공기 기술을 반영하기 위한 것이다. 이러한 기준들은 항공기 운용 상황에 맞게 적절하게 보완되지 못한다면, 국내 운영에서의 안전확보는 물론 해외에서 개발된 항공기의 국내도입 운영에서도 많은 문제점이 발생될 것이므로 조속한 개정이 요구된다.

환경 문제에 있어서 세계의 리더로서 앞 서 가는 구주연합(EU)은 2012년 1월 1일부터 EU 역.내외 항공기를 막론하고 EU 회원국 영토를 출발하고 도착하는 모든 항공기 운항자에 대하여 이들 항공기 엔진에서 배출되는 이산화탄소의 배출량을 규제하는 법 Directive 2008/101/EC를 2008년 제정, 공포하였다. 이에 따라 대한항공과 아시아나를 포함하여 EU를 운항하는 많은 EU 역외 항공사들은 지난 2004-2006년 3년간 연 평균 배출량의 97%만을 2012년 배출하고 2013년부터는 95%만을 배출 허용 받으며 부족한 배출량은 배출권 거래 시장에서 구입하여 충당하여야 한다. 상기 EU 조치는 다음과 같은 법적 문제를 야기한다. 첫째, EU의 법은 범 세계적 환경조약인 교토의정서가 선진국 그룹인 기후변화협약의 Annex I 국가에게만 이산화탄소 등 지구온난화가스 배출을 감축토록 한 것에 반한다. 교토의정서 제2조 2항은 지구온난화가스 감축에 있어서 항공기 배출에 관련한 체제를 ICAO를 통하여 해결하도록 위임하였는데 지역 기구인 EU가 이를 자체 지역에만 적용하기 위하여 작성한 것도 문제이다. 둘째, 역외 항공사들이 EU로 운항하는 데에 있어서 공해와 제3국의 상공을 비행하는데 EU 역내 비행에서 이루어지지 않는 여사한 비행 중 발생하는 배출을 어떤 근거로 EU가 규제할 수 있는가이다. 셋째, EU 회원국들이 Annex I 국가로서 교토의정서 상 항공기의 국내운항 배출에 대하여서는 2012년까지 이미 배출 감축의무를 지고 있음을 감안할 때, 2012년부터 시행되는 항공기 배출 감축 조치에 non-Annex I 국가의 항공 운항자를 끌어들이면서 EU 항공사들이 적어도 2012년에는 예상치 않은 이득을 얻는다는 문제도 발생한다. 과거 유사한 EU 주도의 환경관련 국제 분쟁을 살펴본 후, 상기 EU 조치를 국제법적으로 조명하고 결론에서 EU의 조치에 대한 국내적 대처를 간략기술하였다.

종래의 우주활동은 국가주도의 우주개발을 통해 과학적 혹은 군사적 목적의 활동이 커다란 비중을 차지해 왔으나 점차 우주의 실용적 이용 내지 실용화에 이르는 과정에서 민간기업이 참여하는 상업적 우주활동이 현격한 증가를 보게 되었고 다수의 국가들이 독자적으로 또는 민간기업과의 협력이나 지역적 기구와의 공동사업을 통해서 우주의 상업적인 활용에 가담하고 있다. 그 발전의 폭도 원격탐사, 우주통신, 우주발사 서비스 및 제조업, 에너지 생산분야, 우주운송 및 보험 등 다양한 영역으로 확대일로에 있다. 그런 가운데 특히 각국은 우주의 상업화가 불기피한 발전방향이라는 점을 인식하면서 요람기의 우주산업을 육성하는데 노력을 경주해 오는 한편 국제적인 측면에서는 주로 안전 보장을 위한 고려에서부터 자국의 활동에 관한 국제적 책임(우주조약 제6조)을 이행하기위한 목적으로 우주산업에 대해 엄격한 국가적 규제에 따르도록 해온 것이 사실이다. 이러한 우주에서의 상업적 활동 내지 민간차원의 이용이 우주조약 등 관련 우주국제법의 적용을 받는 우주활동인가 여부에 관해서는 국내외적으로 논란이 있었던 것은 사실이지만 앞서도 논한 바 있듯이 우주조약에서 규정하고 있는 바대로 모든 국가와 전 인류의 이익을 위해 수행되어야 하는 우주활동속에 포함되는 것으로 보아야 할 것이다. 여기서 주목해야 될 것은 상업적 활동 내지 민간차원의 우주이용에 관해 우주국제법의 태도이다. 물론 민간기업의 형태를 취한 상업우주발사활동을 규제하는 일반국제우주법의 규칙은 아직 명료하지 않다. 게다가 상업적 이용의 진전에 따라 대두되는 문제에 대해서 기존의 우주국제법이 한계점을 드러내고 있는 것이 주지의 사실이고 새로이 생성중에 있는 법규범과도 상호 모순되거나 입법적 불비가 있을 수 있는 만큼 이를 극복할 수 방안이 국제 공동체의 부단한 노력을 통해 마련되어야 할 것이다. 현재 우주조약이나 책임협약 등 우주관련 조약에 따르면 기본적으로 국가는 비정부단체나 개인 등의 우주활동에서 야기되는 모든 손해에 대해 국제책임을 지는 것을 원칙으로 하고 있는 바 이를 위해 각 국가는 국내적으로 그들의 활동에 대한 감독책임을 부담하고 있으며 이는 구체적으로는 장차 우주의 상업적 이용을 허가 및 규제하는 당해국가들의 국내법에 반영되어야 할 것이다. 그밖에도 앞서 본 각국의 국내법적 차원에서의 정비도 법리적인 측면에서나 국제협력의 관점에서 기존의 우주국제법과 조화를 이루도록 해야 하겠지만 일반국제법 내지 특별우주법규칙에 있어서도 상업적 우주활동의 발전 추세에 부합하고 또한 양 법체계가 조화를 이룰 수 있도록 재검토하고 경우에 따라 새로운 법제를 마련해야할 필요성도 제기되고 있다.

본 연구는 1997년 이후부터 2022년까지 한국연구재단에 등재된 학술문헌을 '엔젤투자' 와 '엔젤투자자' 그리고 '엔젤투자유치' 의 키워드로 검색하여 조사된 문헌들을 연도, 연구주제, 연구방식, 연구대상, 연구방법의 분류를 통해 국내 엔젤투자에 대한 체계적 문헌고찰을 실시하였다. 본 연구를 통해 국내에서 엔젤투자를 주제로 한 연구현황을 분석하여 해외연구대비 상대적으로 부족한 분야의 주제를 제시하였다. 또한, 엔젤투자 연구의 체계적 확장을 위한 연구방향과 관련한 사회과학적 이론을 제시하였다. 그리고 마지막으로 엔젤투자 분야의 연구 활성화를 위해 어떤 부분들이 필요할지 시사점을 제시하였다. 본 연구로 수집된 문헌들을 분석한 결과 국내의 엔젤투자 관련 연구주제는 엔젤투자자의 특성, 벤처창업기업, 제도 및 정책, 엔젤투자의사, 엔젤투자 유형 등에 초점을 두고 있었으며, 향후 연구에서는 엔젤투자 성과분석, 엔젤투자의 사례연구, 그리고 국내 엔젤투자 규모의 성장과 활성화에 도움이 될 수 있도록 연구의 확장이 필요하다는 결론을 도출하였다. 또한, 벤처창업기업, 엔젤투자 유형, 엑설러레이터, 벤처캐피탈, 제도 및 정책 등 특정 변수에 초점을 둔 연구에서 벗어나 크라우드펀딩, 투자수익률 등 엔젤투자에 관련된 다양한 변수관계를 연구 할 필요가 있다. 특히, 앞으로 엔젤투자 성과를 예측하고 해석하는 데 중요한 역할을 하는 다양한 독립변수들과의 관계를 더 자세히 탐구하는 연구가 더욱 필요하다. 또한, 엔젤투자와 투자 의사결정에 영향을 미치는 다양한 변수들에 대한 이론적 구조를 분석하여 이러한 구조에 대한 질적 및 양적연구가 다방면으로 활성화 될 필요가 있다. 본 연구를 통해 향후 엔젤투자 분야에서 보다 다양한 연구가 진행되길 기대하며, 이러한 연구결과들은 국내 엔젤투자의 활성화에도 기여할 수 있을 것이다.
