전 세계적으로 기업의 중요한 전략적 수단으로 인수합병이 활발히 이루어지고 있고, 지능형 서비스 산업을 포함한 정보기술 산업에서의 인수합병 활동은 꾸준히 활발하게 진행되고 있다. 본 논문에서는 정보기술 산업 내에서 일어나는 인수합병 건에 대해 인수 기업 입장에서의 인수 의도에 초점을 두고 분석하였다. 특히, 두 하드웨어 기업 간, 하드웨어 기업 소프트웨어 기업 간, 두 소프트웨어 기업 간 인수합병 유형에 따라 인수 의도가 어떻게 다른지 비교하고자 하였고, 이를 위해 미국 정보기술 산업 내에서 1995년과 2010년 사이에 일어났던 1003개의 인수합병 건의 자료를 분석하였다. 인수 의도를 파악하는데 있어, 인수 기업의 입장에서 생산비용 절감 의도, 제품 개발 및 개선 의도, 고객층 확장 의도, 고객채널 확장 의도의 네 가지로 구분하여 측정하였다. 분석 결과 생산비용 절감 의도와 고객층 확장 의도는 하드웨어 기업이 피인수 기업일 때 더 많이 나타났고, 제품개발 의도는 하드웨어 기업이 인수 기업일 때 더 많이 나타났다. 그리고, 고객채널 확장 의도는 소프트웨어 기업이 피인수 기업일 때 더 많이 나타났다. 또한, 생산비용 절감 의도, 제품 개발 및 개선 의도를 제품생산 관련활동 의도로, 고객층 확장 의도와 고객채널 확장을 고객관련 활동 의도로 구분하여 비교하였을 때에는, 하드웨어 기업 간 인수합병에 비해, 두 소프트웨어 기업 간 인수합병에서 상대적으로 고객관련 활동 의도가 높은 비중을 나타내고 있음을 알 수 있었다. 활발하게 인수합병이 이루어지고 있는 세계적 추세와는 달리 국내 인수합병거래 규모는 선진국에 비해 매우 적은 수준이다. 본 연구는 인수합병이 보다 활발하게 이루어지고 있는 미국기술정보 산업에서의 인수 의도를 분석하여, 국내에서 인수합병 활동을 활성화하는 방안을 분석 및 개발하는데 기여하고자 한다.

Consumers differ in the way they make a purchase. An audio mania would willingly make a bold, yet serious, decision to buy a top-of-the-line home theater system, while he is not interested in replacing his two-decade-old shabby car. On the contrary, an automobile enthusiast wouldn't mind spending forty thousand dollars to buy a new Jaguar convertible, yet cares little about his junky component system. It is product involvement that helps us explain such differences among individuals in the purchase style. Product involvement refers to the extent to which a product is perceived to be important to a consumer (Zaichkowsky, 2001). Product involvement is an important factor that strongly influences consumer's purchase decision-making process, and thus has been of prime interest to consumer behavior researchers. Furthermore, researchers found that involvement is closely related to perceived risk (Dholakia, 2001). While abundant research exists addressing how product involvement relates to overall perceived risk, little attention has been paid to the relationship between involvement and different types of perceived risk in an electronic commerce setting. Given that perceived risk can be a substantial barrier to the online purchase (Jarvenpaa, 2000), research addressing such an issue will offer useful implications on what specific types of perceived risk an online firm should focus on mitigating if it is to increase sales to a fullest potential. Meanwhile, past research has focused on such consumer responses as information search and dissemination as a consequence of involvement, neglecting other behavioral responses like online merchant selection. For one example, will a consumer seriously considering the purchase of a pricey Guzzi bag perceive a great degree of risk associated with online buying and therefore choose to buy it from a digital storefront rather than from an online marketplace to mitigate risk? Will a consumer require greater trust on the part of the online merchant when the perceived risk of online buying is rather high? We intend to find answers to these research questions through an empirical study. This paper explores the impact of enduring product involvement and perceived risks on required trust level, and further on online merchant choice. For the purpose of the research, five types or components of perceived risk are taken into consideration, including financial, performance, delivery, psychological, and social risks. A research model has been built around the constructs under consideration, and 12 hypotheses have been developed based on the research model to examine the relationships between enduring involvement and five components of perceived risk, between five components of perceived risk and required trust level, between enduring involvement and required trust level, and finally between required trust level and preference toward an e-tailer. To attain our research objectives, we conducted an empirical analysis consisting of two phases of data collection: a pilot test and main survey. The pilot test was conducted using 25 college students to ensure that the questionnaire items are clear and straightforward. Then the main survey was conducted using 295 college students at a major university for nine days between December 13, 2010 and December 21, 2010. The measures employed to test the model included eight constructs: (1) enduring involvement, (2) financial risk, (3) performance risk, (4) delivery risk, (5) psychological risk, (6) social risk, (7) required trust level, (8) preference toward an e-tailer. The statistical package, SPSS 17.0, was used to test the internal consistency among the items within the individual measures. Based on the Cronbach's ${\alpha}$ coefficients of the individual measure, the reliability of all the variables is supported. Meanwhile, the Amos 18.0 package was employed to perform a confirmatory factor analysis designed to assess the unidimensionality of the measures. The goodness of fit for the measurement model was satisfied. Unidimensionality was tested using convergent, discriminant, and nomological validity. The statistical evidences proved that the three types of validity were all satisfied. Now the structured equation modeling technique was used to analyze the individual paths along the relationships among the research constructs. The results indicated that enduring involvement has significant positive relationships with all the five components of perceived risk, while only performance risk is significantly related to trust level required by consumers for purchase. It can be inferred from the findings that product performance problems are mostly likely to occur when a merchant behaves in an opportunistic manner. Positive relationships were also found between involvement and required trust level and between required trust level and online merchant choice. Enduring involvement is concerned with the pleasure a consumer derives from a product class and/or with the desire for knowledge for the product class, and thus is likely to motivate the consumer to look for ways of mitigating perceived risk by requiring a higher level of trust on the part of the online merchant. Likewise, a consumer requiring a high level of trust on the merchant will choose a digital storefront rather than an e-marketplace, since a digital storefront is believed to be trustworthier than an e-marketplace, as it fulfills orders by itself rather than acting as an intermediary. The findings of the present research provide both academic and practical implications. The first academic implication is that enduring product involvement is a strong motivator of consumer responses, especially the selection of a merchant, in the context of electronic shopping. Secondly, academicians are advised to pay attention to the finding that an individual component or type of perceived risk can be used as an important research construct, since it would allow one to pinpoint the specific types of risk that are influenced by antecedents or that influence consequents. Meanwhile, our research provides implications useful for online merchants (both online storefronts and e-marketplaces). Merchants may develop strategies to attract consumers by managing perceived performance risk involved in purchase decisions, since it was found to have significant positive relationship with the level of trust required by a consumer on the part of the merchant. One way to manage performance risk would be to thoroughly examine the product before shipping to ensure that it has no deficiencies or flaws. Secondly, digital storefronts are advised to focus on symbolic goods (e.g., cars, cell phones, fashion outfits, and handbags) in which consumers are relatively more involved than others, whereas e- marketplaces should put their emphasis on non-symbolic goods (e.g., drinks, books, MP3 players, and bike accessories).

세계가 급변하고 시시각각 발전하는 기술 속에서 전시 산업은 국가와 기업의 중요한 홍보 수단으로 부각되고 있다. 특히, 전시회에 참여하는 참여업체는 상품 또는 서비스를 전시하고 메시지를 전달하기 위해 마련된 개별 전시공간을 통해 기업들과 소비자들에게 단기간에 신제품과 신기술에 대한 정보를 제공할 수 있으며 국내외 시장의 욕구와 추세변화 및 경쟁업체들에 대한 정보를 파악할 수 있다. 참여업체들은 이러한 참가 목적의 달성을 위해 다양한 프로모션을 계획하고 실행하며 프로모션 정보를 참관객에게 실시간으로 제공할 수 있는 스마트 전시 환경의 구축은 이전보다 다양한 프로모션 기법의 적용 및 실행을 가능하게 하였다. 하지만, 이러한 스마트 전시 환경의 발전에도 불구하고 현재 실행되고 있는 프로모션은 참관객의 욕구나 목표에 대한 이해가 부족한 상태에서 무차별적인 매스마케팅 형태로 진행되어 그 본래의 목적을 상실하고 있다. 따라서, 본 연구에서는 참여업체의 차별화된 프로모션의 계획과 실행을 위해 기존에 널리 사용되는 마케팅 기법인 STP 전략의 프로세스를 도입하여 스마트 전시 환경에서 프로모션에 적합한 참관객을 자동적으로 선정하여 프로모션 정보를 제공하는 시스템을 제안하였다. 특히, 본 연구에서는 다음과 같은 스마트 전시회의 특성을 고려한다. 먼저, 전시회는 전시업체가 관람객과 상호작용하기 위해 모인 일시적이고 시간에 민감한 시장이다. 따라서, 불충분한 기존 참관객의 정보를 이용하는 것이 아닌 신규 참관객 분석의 관점에서 서비스를 제공할 수 있어야 한다. 두 번째로, 스마트 전시 환경에서는 참관객의 정보를 실시간으로 획득할 수 있다는 장점이 있는 반면에 데이터의 분석 및 서비스의 제공이 실시간으로 이루어져야 한다. 마지막으로, 참관객이 스마트 전시 환경에서 만들어 내는 데이터를 활용하는 기법이 필요하다. 스마트 전시 환경에서는 유용한 데이터를 실시간으로 획득할 수 있어 참관객이 전시회 내에서 하는 활동을 분석하는 행위적 세분화에 근거한 접근방식이 필요하다. 이러한 특성을 고려하여 본 연구에서는 제안한 시스템을 실제 전시회에 파일럿 시스템 형태로 적용하여 참관객을 실시간으로 분류 및 분석하고 각 메시지에 대한 성과를 측정하는 실험을 진행하였다. 그 결과, 전시 참관객의 행동 패턴을 4가지로 분류하여 각 군집별 특성을 프로모션 메시지의 성과로 측정하여 그에 적합한 프로모션 전략을 도출하였다. 이러한 프로모션 전략은 실제 전시 참여업체의 프로모션 기획 및 실행에 중요한 전략적 도구로 사용되어 프로모션 성과를 높일 수 있을 것으로 기대된다.

UGC(User Generated Contents) is emerging as the center of e-business in the web 2.0 era. The trend reflects changing roles of users in production and consumption of contents on websites and helps us to understand new strategies of websites such as web portals and social network websites. Nowadays, we consume contents created by other non-professional users for both utilitarian (e.g., knowledge) and hedonic values (e.g., fun). Also, contents produced by ourselves (e.g., photo, video) are posted on websites so that our friends, family, and even the public can consume those contents. This means that non-professionals, who used to be passive audience in the past, are now creating contents and share their UGCs with others in the Web. Accessible media, tools, and applications have also reduced difficulty and complexity in the process of creating contents. Realizing that users create plenty of materials which are very interesting to other people, media companies (i.e., web portals and social networking websites) are adjusting their strategies and business models accordingly. Increased demand of UGC may lead to website visits which are the source of benefits from advertising. Therefore, they put more efforts into making their websites open platforms where UGCs can be created and shared among users without technical and methodological difficulties. Many websites have increasingly adopted new technologies such as RSS and openAPI. Some have even changed the structure of web pages so that UGC can be seen several times to more visitors. This mainstream of UGCs on websites indicates that acquiring more UGCs and supporting participating users have become important things to media companies. Although those companies need to understand why general users have shown increasing interest in creating and posting contents and what is important to them in the process of productions, few research results exist in this area to address these issues. Also, behavioral process in creating video UGCs has not been explored enough for the public to fully understand it. With a solid theoretical background (i.e., theory of implementation intentions), parts of our proposed research model mirror the process of user behaviors in creating video contents, which consist of intention to upload, intention to edit, edit, and upload. In addition, in order to explain how those behavioral intentions are developed, we investigated influences of antecedents from three motivational perspectives (i.e., intrinsic, editing software-oriented, and website's network effect-oriented). First, from the intrinsic motivation perspective, we studied the roles of self-expression, enjoyment, and social attention in forming intention to edit with preferred editing software or in forming intention to upload video contents to preferred websites. Second, we explored the roles of editing software for non-professionals to edit video contents, in terms of how it makes production process easier and how it is useful in the process. Finally, from the website characteristic-oriented perspective, we investigated the role of a website's network externality as an antecedent of users' intention to upload to preferred websites. The rationale is that posting UGCs on websites are basically social-oriented behaviors; thus, users prefer a website with the high level of network externality for contents uploading. This study adopted a longitudinal research design; we emailed recipients twice with different questionnaires. Guided by invitation email including a link to web survey page, respondents answered most of questions except edit and upload at the first survey. They were asked to provide information about UGC editing software they mainly used and preferred website to upload edited contents, and then asked to answer related questions. For example, before answering questions regarding network externality, they individually had to declare the name of the website to which they would be willing to upload. At the end of the first survey, we asked if they agreed to participate in the corresponding survey in a month. During twenty days, 333 complete responses were gathered in the first survey. One month later, we emailed those recipients to ask for participation in the second survey. 185 of the 333 recipients (about 56 percentages) answered in the second survey. Personalized questionnaires were provided for them to remind the names of editing software and website that they reported in the first survey. They answered the degree of editing with the software and the degree of uploading video contents to the website for the past one month. To all recipients of the two surveys, exchange tickets for books (about 5,000~10,000 Korean Won) were provided according to the frequency of participations. PLS analysis shows that user behaviors in creating video contents are well explained by the theory of implementation intentions. In fact, intention to upload significantly influences intention to edit in the process of accomplishing the goal behavior, upload. These relationships show the behavioral process that has been unclear in users' creating video contents for uploading and also highlight important roles of editing in the process. Regarding the intrinsic motivations, the results illustrated that users are likely to edit their own video contents in order to express their own intrinsic traits such as thoughts and feelings. Also, their intention to upload contents in preferred website is formed because they want to attract much attention from others through contents reflecting themselves. This result well corresponds to the roles of the website characteristic, namely, network externality. Based on the PLS results, the network effect of a website has significant influence on users' intention to upload to the preferred website. This indicates that users with social attention motivations are likely to upload their video UGCs to a website whose network size is big enough to realize their motivations easily. Finally, regarding editing software characteristic-oriented motivations, making exclusively-provided editing software more user-friendly (i.e., easy of use, usefulness) plays an important role in leading to users' intention to edit. Our research contributes to both academic scholars and professionals. For researchers, our results show that the theory of implementation intentions is well applied to the video UGC context and very useful to explain the relationship between implementation intentions and goal behaviors. With the theory, this study theoretically and empirically confirmed that editing is a different and important behavior from uploading behavior, and we tested the behavioral process of ordinary users in creating video UGCs, focusing on significant motivational factors in each step. In addition, parts of our research model are also rooted in the solid theoretical background such as the technology acceptance model and the theory of network externality to explain the effects of UGC-related motivations. For practitioners, our results suggest that media companies need to restructure their websites so that users' needs for social interaction through UGC (e.g., self-expression, social attention) are well met. Also, we emphasize strategic importance of the network size of websites in leading non-professionals to upload video contents to the websites. Those websites need to find a way to utilize the network effects for acquiring more UGCs. Finally, we suggest that some ways to improve editing software be considered as a way to increase edit behavior which is a very important process leading to UGC uploading.

When recognition of the Ghi(氣) which exist in all things, is changed on the aspects of the science of nursing, the view of health and nursing will be more efficient and can be developed as the proper concept for Korean culture. I think it is nessary to confirm which philosophical basis of the will be applicable to nursing and how to it has to be developed. Therefore I can for the research of the Ghi phenomena to attain the Thoughts of philosophy that is appropriate to expound those phenomena. And I attempt to induct "the fusion of horizons" to unify the view of the I world between Korea and the West. The Ghi is very energetic and omnipresent among the universe, Nature, and the human being. So it can organize all the primary elements of mental and I physical function of human as like life, mind, breath, feeling, energy, etc. A general concept of the Ghi is described as follows ; (1) The Ghi is the origin and essence to organize the universe, Nature, and the human being. (2) It is the perpetually movable thing. (3) And there are continuous transmission between the Ghi of the universe and the human through 'body, mind, and soul. For review on the philosophic basis of the Ghi, I studied out the identity of the doctrine of Li and Ch'i(理氣論) in the field of philosophy of Korea and the West. In Korea, the concept of the Vigor is based on Ch'i monolism(기일원론) and Li Ch'i dualism (이기이원론) of Yul-gok Lee's, Toi-kye Lee's, Hwa-dam's, and/or Hekang's. These are indispensable for the view of the world of Korea as Metaphysical ideology, Concrete science, Materialism, Ontology, and Epistemology. From the viewpoint of the philosophy of the West, the doctrine of Li and Ch'i(이기론) of Korea is identical with the doctrine of Li and Ch'i(이기론) of Joo-ja, Idea of Plato, Metaphysics of Aristotle, World Spirit(Weltgeist) of Hegel, and Existentialism of Heidegger. In the nursing theory of the West, some of them referred to the Ghi as like Energy field theory of Rogers and Energy exchange of Neuman. Though there are different in terminology, "energy" and the "Ghi" are induced comparable therapeutic action between the human and the environments. With the nursing theory of Korea, I have made an attempt to compare the Ghi with metaparadigm of nursing-the human being, the environment, the health, and the nursing. For the most part, the alternative therapy is resonable to the frame of the nursing theory of Korea. It is easy to apply alternative therapy on the every spot of nursing. So this therapy could be a kind of forms as nursing therapy in the nursing centers where take the duties of supporting in local societies. In result, independent nursing intervention will be activated by the nurse who puts up with the major parts. It is available to apply this therapy to palliation of pain, insomnia of infant, Sanhujori (산후조리), pain of menstruation, arthritis. And the alternative therapy makes it possible to propose the nursing model which represent originality, tradition, and history of the nursing of Korea. Additionally, in the field of the nursing, it is indispensable to choose a suitable methodology which is considered whether it is matched with a theory of philosophy in the boundary and object of the research. Because there are many way to get the knowledge of nursing related to the Ghi. In the science of nursing, context of sociocultural background and frame are required to understand the person who need to take care of (nursing client). But the value systems of the West and the East are distinctive each other as well as the behavior of health persuance. Therefore it is the basic research data of great worth to review philosophical the Ghi phenomena which is well known to Korean.

1, The Purpose of Study This is a study on the Evaluation of the operating of Fisheries Extension Services of Korea, for performing the activities such as guiding fisheries technique as well as offering industrial information to the fishermen in fishing village. By doing so, the Fisheries Extension Sevices(FES) can materialize the continued growth of fisheries, the social and economic development of fishing village, and the increase in income by enhancing the knowledge level of Fishermen, etc. In performing fisheries policy, this activity plays a great role on the research and development activity, and it has become practical since 1976 in Korea. In order to meet immediately with the problem of fisheries technical innovation and rapid environmental changes surrounding the fisheries, the fishermen should not only enhance their scientific and comprehensive capacity in fisheries technique but abtain various effective information. Generally, as most of all the fishemen are poor in the managerial structure and scattered in fishing villages, they have little opportunity in the contact of information. As a result, it is nessessary for the FES to perform the fishing business by the extension service officials who has received special training and acquired fisheries know-how in these fields. And yet, FES is under the unfullfilled circumstance in such factors as manpower, technical know-how, equipment, and the service system etc., which is required in promoting the social, economic development of fishing village and in resolving the high technique demand of fisherman. This study on the fisheries extension services have been studied from those backgrounds. 2. Research Method The data of collecting methods which were necessary in carrying out this study was adopted by the questionaire research on the present extension service activity, through the subject of the extension services (driving agency of the work and the officials), the object(fishemen) and the 3rd observers to the extension services (the authorities concerned). The research sample was taken by the sampling extraction of total 1, 774 men from the above 3 groups. And the research was carried out from August, 1986 to October, 1986, supported from the Fisheries Extension Office (FEO) located in field during the research process. In this study, the levels of the extension operating were determined and estimated in accordance with the extension service method, morale of extension service officials and the extension service system, etc. through the collected data of the research questionaire paper. And based on this result, the essential conditions of the extension services were grasped, and also we tried to present the various activity plan necessary to promote the operating of the extension services. The questionaire research data was calculated by the computer center of National Fisheries University of Pusan, and the total result was again tried on the one demension analysis along with two dimension analysis to search out the relativity between the questionaire, and the statistical test was done $\chi$$^2$test in significance level of l~5%. 3. Contents of Study This study consists of 7 chapters and the contents are as follows : Chapter I : The object and method of the study Chapter II : The assessment and analysis of the extension services Chapter III : The contents and method of the extension services Chapter IV : Analysis of the essential conditions for the extension services Chapter V : The evaluation of activities of extension services Chapter Ⅵ : Conclusion.4. Results and RecommendationTherefore, the results of this study estimated by logical process and analysis are as follows : 1) Most of Korean fishing villages and coastal fishermen have shown much concerns about fisheries technique and social changes, thus many of them were confronted with new problems on how to adapt and to meet changes. 2) Majority of fishermen estimated FEO as an organization of specific technologies with all the thing concerning the fisheries technique in general. Therefore the fishermen wanted to utilize the FEO as an adaptable method for the modern fisheries techniques as well as the environmental changes. 3) In contrast with the fast changes of the fisheries technique, the complexity and variety of technical system and the broadness of fishing village and fishermen, it was revealed that the necessary factors such as the facilities, manpower, budget, and the level of applying techniques of the FEO located in field were highly insufficient. Accordingly, the guiding efficiency was low and the extension services did not provide full solution to the various request from fishermen. 4) It is possible to classify the activation factor for the extension service into two large dimension ; personal dimension relevant to guidance officials and work dimension relevant to the organization. And it was found that the activation level of the work dimension was far lower than the personal dimension between them. So, the activation should be done first in the dimesion to promote the activation of the extension services. 5) The extension services officials are now demoralized in general, thus it is necessary to take reality into consideration : the expense of activity, the adequate endowment of activity scope and the reasonable operation of the position class, etc to enhance its morale. However, in order to do the FES activation, first of all, the systems should be established which is lain unsettled stage until now. And there must be change in the understanding of government i.e. the fisheries extension services are the essential policy subject to build up the base of fisheries growth and modernize the fisheries management. And it should be driven positively with the recognition of the "lasting project".g project".uot;.

기후변화협약과 탄소배출권문제 등 환경에 관한 관심과 규제 등이 국제적 주요 관심 사항이 되고 있는 상황에서 농업생산에 대한 환경영향평가의 필요성이 대두되고 있다. 현재 우리나라는 환경부에서 시행하는 탄소성적표지제도 도입에서 농업분야의 LCI (Life Cycle Invemtory)database 부재를 이유로 1차 농산물을 대상에서 제외하고 있다. 따라서 농산물 탄소성적표지제도 도입을 위한 농업분야 LCI database에 대한 연구와 구축이 시급한 실정이다. 따라서 본 연구는 농업생산체계에 대한 LCA 적용을 위하여 시설상추를 대상으로 LCI 구축과 LICA 수행을 위한 방법론을 고찰하였다. LCA의 방법론은 ISO 14040 규격에 의거하여 연구 목적 및 범위, LCI분석 (전과정 목록분석), LCIA(전과정 영향평가), 해석의 단계로 구성되었다. 연구 목적은 시설 상추재배체계에 대한 LCA 방법론 적용이며, 기능단위는 상추 1 kg 생산으로 하였다. LCI 구축을 위한 영농 투입물과 산출물에 대한 데이터 수집은 농진청의 농축산물소득자료를 중심으로 관련 통계, 문헌자료를 통하여 수집하였다. LCI 구축을 위한 자료 수집결과 상추를 재배할 때 투입되는 물질 중 유기질 비료와 무기질 비료의 시용과, 식물보호제의 투입이 주요배출인자로 분석되었다. 농업활동으로 배출되는 주요 환경부하물질은 비료가 시용된 토양으로부터 대기로 발생되는 $N_2O$와 수계로 배출되는 ${NO_3}^-$, ${PO_4}^-$과 농약잔류물질로부터 발생되는 유기화학물질, 농기계에 쓰이는 화석연료 연소에 의한 대기오염물질 등 이었다. LCIA는 해외의 LCA 방법론과 LCA적용사례를 조사하여 농업분야 LCIA 방법론에 대하여 고찰하였다. LCIA는 분류화, 특성화, 정규화(일반화), 가중화의 4단계로 이루어지며, 이 중 분류화와 특성화는 의무절차이고, 정규화와 가중화는 선택사항이다. 해석단계는 LCI 분석결과와 LCIA 결과에 대하여 검증하고, 결과로부터 도출된 환경적 문제점과 개선안 등을 제시한다. LCA 수행에 사용하는 국내 소프트웨어는 지경부와 환경부에서 개발하여 보급하고 있는 'PASS'와 'TOTAL' 이다. 그러나 국내 프로그램에 적용되고 있는 환경영향평가 모델은 국외에서 개발한 기존모델들이다. 그러므로 보다 정확한 농업분야 LCA 분석이 가능하도록 추후 국내 농업환경에 적합한 영향평가 모델 및 특성화, 일반화, 가중화 계수의 선정 등이 이루어져야 할 것이다.

개념적 모델링(conceptual modeling)은 정보시스템 개발에 있어서 중요한 역할을 수행한다. 그럼에도 불구하고 이를 성공적으로 수행하기 위해 어떠한 방법을 채택해야 하고 그 결과를 어떻게 평가해야 할 것인지에 대한 이론적 성과는 충분하지 않다. 부분과 전체에 대한 개념적 모델링을 평가하기 위해 온톨로지 이론을 도입한 최근의 연구, "Representing Part-Whole Relations in Conceptual Modeling : An Empirical Evaluation"(Shanks et al., 2008)은 개념적 모델링 평가에 실험법을 도입했다는 긍정적인 측면에도 불구하고 비판에 직면했다. 또한 이에 대한 반대 의견이 제시되면서 개념적 모델링을 연구하거나 실무에 활용하려는 사람들에게 혼란을 초래하고 있다. 본 연구는 Bunge-Wand-Weber 온톨로지의 이론적 배경과 성과를 검토하고 논쟁에서 제외된 부분과 전체에 관한 이론적 논의를 추가하여 과연 Shanks et al.의 연구에 대한 비판이 타당한 것인지 살펴본다. 이들 연구에 대한 비판이 주로 실험적 방법의 오류를 지적한 것과 비교하여 본 연구는 Shanks et al.의 연구가 번지(Bunge) 온톨로지를 잘못 활용하고 있으며, 패러다임의 문제라는 지적은 그 근거가 확실하지 않으며, 부분과 전체에 관한 연구개념의 타당성을 확보하지 않았음을 밝혔다. 본 논문을 통해 우리는 Shanks et al.의 연구는 실증적 타당성에 대한 문제뿐만 아니라 기존의 온톨로지 개념들을 적절히 활용하지 않았고 결과적으로 부분-전체에 관한 개념적 모델링 이론에 기여하기보다는 서로 다른 모델링 패턴 간의 단순한 비교에 그쳤다는 점을 주장한다.
