  • 서울시 간선축자전거도로의 경우 한강변을 중심으로 축이 형성되어 있어 이용자가 많은 한강변 주변에 거주자들의 이용이 높은 반면, 도심지역 거주자들의 한강변자전거도로의 이용도는 낮다. 이는 한강변자전거도로를 연결하는 자전거도로와 도심지역의 자전거도로와의 연계성이 떨어지는 것으로 판단되며, 한강이남자전거도로의 접근성을 높이기 위한 정책보다는 시설위주의 정책을 시행하고 있다. 한강변자전거도로의 이용만이 아닌 서울시 자전거도로의 연계성을 높이기 위한 합리적인 개선책이 필요한 시점이라 할 수 있다. 본 연구의 목적은 한강이남자전거도로를 대상으로 자전거도로의 접근성을 분석하기 위하여 한강이남지역의 공간구조를 Space Syntax Model을 이용하여 현재 및 자전거간선축설치계획 후와 일반도로설치 후를 비교하여 강서 강동지역간의 연계성을 분석하고, 그에 따른 변화를 예측하는 것이다. 본 연구에서 사용된 주요 분석방법은 Space Syntax Model을 이용한 한강이남자전거도로의 특성을 분석하였다. 결과적으로, 강서 강동지역간 자전거도로 연결 시 한강이 남자전거도로의 접근성은 향상하였으나, 공간구조명료도($R^2$)는 낮아지는 것으로 나타나 현재에 비해 지역 전체에 예측률이 낮다고 할 수 있다. 이는 현재의 한강이남자전거도로와 간선축 설치계획안 일반도로설치안 비교 시 상대적으로 가장 높은 공간구조명료도를 나타내어 자전거도로가 지역 간 연결이 이루어지기 전인 도로형태이기 때문인 것으로 분석되었다.

  • Knowledge is an essential strategic weapon for sustaining competitive advantage and is the key determinant for organizational growth. When knowledge is shared and disseminated throughout the organization, it increases an organization's value by providing the ability to respond to new and unusual situations. The growing importance of knowledge as a critical resource has forced executives to pay attention to their organizational knowledge. Organizations are increasingly undertaking knowledge management initiatives and making significant investments. Knowledge sourcing is considered as the first important step in effective knowledge management. Most firms continue to make an effort to realize the benefits of knowledge management by using various knowledge sources effectively. Appropriate knowledge sourcing strategies enable organizations to create, acquire, and access knowledge in a timely manner by reducing search and transfer costs, which result in better firm performance. In response, the knowledge management literature has devoted substantial attention to the analysis of knowledge sourcing strategies. Many studies have categorized knowledge sourcing strategies into intemal- and external-oriented. Internal-oriented sourcing strategy attempts to increase firm performance by integrating knowledge within the boundary of the firm. On the contrary, external-oriented strategy attempts to bring knowledge in from outside sources via either acquisition or imitation, and then to transfer that knowledge across to the organization. However, the extant literature on knowledge sourcing strategies focuses primarily on large organizations. Although many studies have clearly highlighted major differences between large and small firms and the need to adopt different strategies for different firm sizes, scant attention has been given to analyzing how knowledge sourcing strategies affect firm performance in small firms and what are the differences between small and large firms in the patterns of knowledge sourcing strategies adoption. This study attempts to advance the current literature by examining the impact of knowledge sourcing strategies on small firm performance from a holistic perspective. By drawing on knowledge based theory from organization science and complementarity theory from the economics literature, this paper is motivated by the following questions: (1) what are the adoption patterns of different knowledge sourcing strategies in small firms (i,e., what sourcing strategies should be adopted and which sourcing strategies work well together in small firms)?; and (2) what are the performance implications of these adoption patterns? In order to answer the questions, this study developed three hypotheses. First hypothesis based on knowledge based theory is that internal-oriented knowledge sourcing is positively associated with small firm performance. Second hypothesis developed on the basis of knowledge based theory is that external-oriented knowledge sourcing is positively associated with small firm performance. The third one based on complementarity theory is that pursuing both internal- and external-oriented knowledge sourcing simultaneously is negatively or less positively associated with small firm performance. As a sampling frame, 700 firms were identified from the Annual Corporation Report in Korea. Survey questionnaires were mailed to owners or executives who were most erudite about the firm s knowledge sourcing strategies and performance. A total of 188 companies replied, yielding a response rate of 26.8%. Due to incomplete data, 12 responses were eliminated, leaving 176 responses for the final analysis. Since all independent variables were measured using continuous variables, supermodularity function was used to test the hypotheses based on the cross partial derivative of payoff function. The results indicated no significant impact of internal-oriented sourcing strategies while positive impact of external-oriented sourcing strategy on small firm performance. This intriguing result could be explained on the basis of various resource and capital constraints of small firms. Small firms typically have restricted financial and human resources. They do not have enough assets to always develop knowledge internally. Another possible explanation is competency traps or core rigidities. Building up a knowledge base based on internal knowledge creates core competences, but at the same time, excessive internal focused knowledge exploration leads to behaviors blind to other knowledge. Interestingly, this study found that Internal- and external-oriented knowledge sourcing strategies had a substitutive relationship, which was inconsistent with previous studies that suggested complementary relationship between them. This result might be explained using organizational identification theory. Internal organizational members may perceive external knowledge as a threat, and tend to ignore knowledge from external sources because they prefer to maintain their own knowledge, legitimacy, and homogeneous attitudes. Therefore, integrating knowledge from internal and external sources might not be effective, resulting in failure of improvements of firm performance. Another possible explanation is small firms resource and capital constraints and lack of management expertise and absorptive capacity. Although the integration of different knowledge sources is critical, high levels of knowledge sourcing in many areas are quite expensive and so are often unrealistic for small enterprises. This study provides several implications for research as well as practice. First this study extends the existing knowledge by examining the substitutability (and complementarity) of knowledge sourcing strategies. Most prior studies have tended to investigate the independent effects of these strategies on performance without considering their combined impacts. Furthermore, this study tests complementarity based on the productivity approach that has been considered as a definitive test method for complementarity. Second, this study sheds new light on knowledge management research by identifying the relationship between knowledge sourcing strategies and small firm performance. Most current literature has insisted complementary relationship between knowledge sourcing strategies on the basis of data from large firms. Contrary to the conventional wisdom, this study identifies substitutive relationship between knowledge sourcing strategies using data from small firms. Third, implications for practice highlight that managers of small firms should focus on knowledge sourcing from external-oriented strategies. Moreover, adoption of both sourcing strategies simultaneousiy impedes small firm performance.

  • 쌀가루는 많은 식품 가공에 이용된다. 그러나 밀가루 반죽이 빵과 면을 포함한 많은 식품 가공 제품에 적합한 반면에, 쌀로 만든 반죽은 신장성과 탄력성이 부족하다. 고분자 글루테닌 서브유닛(HMW-GS)은 밀의 가공 적성을 결정하는데 중요한 역할을 한다. 본 연구에서, 우리는 아그로박테리움(Agrobacterium) 동시 형질전환법을 이용하여 한국 밀 품종인 '조경'으로부터 HMW-GS를 암호화하는 밀 Glu-1Dy10 유전자를 발현하는 marker-free 형질전환 벼 식물체를 개발하였다. 오직 Glu-1Dy10 유전자와 HPTII (hygromycin phosphotransferase II) 저항성 유전자만을 포함하는 분리된 DNA 조각들로 구성된 두 가지 발현 카셋트(cassettes)를 독립적으로 아그로박테리움(Agrobacterium) EHA105 에 도입하였다. Glu-1Dy10 또는 HPTII를 함유하는 EHA105 를 각각 3:1 비율로 벼 캘러스에 접종하였다. 290개의 하이그로마이신(hygromycin) 저항성 $T_0$ 식물체 중에서 우리는 벼 게놈에 Glu-1Dy10과 HPTII 유전자가 모두 삽입된 29개의 형질전환 라인을 획득하였다. 우리는 Glu-1Dy10 유전자가 벼 게놈 내로 도입된 것을 Southern blot 분석을 통해 다시 확인하였다. 형질전환 벼 종자에서 Glu-1Dy10의 전사(Transcripts)와 단백질을 semi-quantitative RT-PCR과 Western blot 분석을 통해서 확인하였다. 최종적으로, 오직 Glu-1Dy10 유전자를 갖는 marker-free 식물체를 $T_1$ 세대에서 성공적으로 선발할 수 있었다.

  • 고등학교 과학교과서의 개선을 위한 제안을 제시하기 위해 한국과 미국 고등학교 지구과학 교과서의 지질학 영역에 있는 탐구 활동이 탐구내용, 탐구과정, 탐구상황 면에서 평가되었다. 탐구활동의 내용에서, 한국 교과서는 단원 당 5.8개로 미국 교과서의 단원 당 4개보다 더 많은 탐구활동 개수를 포함하고 있었다. 한국 교과서는 대부분 도표나 그래프 등 자료해석에 관련된 탐구활동을 포함하고 있고 미국 교과서는 스스로 조작하는 실험이나 자료변형 그리고 직접설계 할 수 있는 탐구활동 기회를 제공하고 있다. 탐구활동 1개당 사용된 탐구과정 개수는 한국 교과서가 평균 1.8개인 반면 미국 교과서는 3개로 미국 교과서가 한국 교과서보다 더욱 다양한 탐구과정을 사용한다는 것을 알 수 있다. 모든 교과서에서 가장 많이 사용된 탐구과정 요소는 추리와 자료해석으로 이 두 요소의 비율은 한국 교과서는 평균 73.3%이고 미국 교과서는 46.2%였다. 즉 한국 교과서는 특정 탐구과정 요소만을 강조하였고, 이런 고르지 못한 탐구과정 요소의 분포는 학생의 통합능력 신장에 저해요인으로 작용할 수도 있을 것으로 판단된다. 특히 통합적 탐구과정에서 미국교과서는 7개의 모든 요소가 다 제시되었지만 한국 교과서는 단지 2개 내지 4개의 요소만이 제시되어 한국 교과서가 미국 교과서보다 학생들이 다양한 탐구능력을 함양할 수 있게 하는 탐구활동을 제공하는데 있어 취약점을 갖고 있다는 것을 말해 준다. 탐구상황 분석에서 한국교과서는 다소 단편적 인이고 실생활과 관련이 낮은 탐구 상황이 제공되었고, 미국 교과서는 좀 더 실생활과 관련되어 적용된 탐구 상황의 내용들로 구성되어 있음을 보여주었다.

  • 가짜뉴스가 전세계적 이슈로 부상한 최근 수년간 가짜뉴스 문제 해결을 위한 논의와 연구가 지속되고 있다. 특히 인공지능과 텍스트 분석을 이용한 자동화 가짜 뉴스 탐지에 대한 연구가 주목을 받고 있는데, 대부분 문서 분류 기법을 이용한 연구들이 주를 이루고 있는 가운데 문서 요약 기법은 지금까지 거의 활용되지 않았다. 그러나 최근 가짜뉴스 탐지 연구에 생성 요약 기법을 적용하여 성능 개선을 이끌어낸 사례가 해외에서 보고된 바 있으며, 추출 요약 기법 기반의 뉴스 자동 요약 서비스가 대중화된 현재, 요약된 뉴스 정보가 국내 가짜뉴스 탐지 모형의 성능 제고에 긍정적인 영향을 미치는지 확인해 볼 필요가 있다. 이에 본 연구에서는 국내 가짜뉴스에 요약 기법을 적용했을 때 정보 손실이 일어나는지, 혹은 정보가 그대로 보전되거나 혹은 잡음 제거를 통한 정보 획득 효과가 발생하는지 알아보기 위해 국내 뉴스 데이터에 추출 요약 기법을 적용하여 '본문 기반 가짜뉴스 탐지 모형'과 '요약문 기반 가짜뉴스 탐지 모형'을 구축하고, 다수의 기계학습 알고리즘을 적용하여 두 모형의 성능을 비교하는 실험을 수행하였다. 그 결과 BPN(Back Propagation Neural Network)과 SVM(Support Vector Machine)의 경우 큰 성능 차이가 발생하지 않았지만 DT(Decision Tree)의 경우 본문 기반 모델이, LR(Logistic Regression)의 경우 요약문 기반 모델이 다소 우세한 성능을 보였음을 확인하였다. 결과를 검증하는 과정에서 통계적으로 유의미한 수준으로는 요약문 기반 모델과 본문 기반 모델간의 차이가 확인되지는 않았지만, 요약을 적용하였을 경우 가짜뉴스 판별에 도움이 되는 핵심 정보는 최소한 보전되며 LR의 경우 성능 향상의 가능성이 있음을 확인하였다. 본 연구는 추출요약 기법을 국내 가짜뉴스 탐지 연구에 처음으로 적용해 본 도전적인 연구라는 점에서 의의가 있다. 하지만 한계점으로는 비교적 적은 데이터로 실험이 수행되었다는 점과 한 가지 문서요약기법만 사용되었다는 점을 제시할 수 있다. 향후 대규모의 데이터에서도 같은 맥락의 실험결과가 도출되는지 검증하고, 보다 다양한 문서요약기법을 적용해 봄으로써 요약 기법 간 차이를 규명하는 확장된 연구가 추후 수행되어야 할 것이다.

새로운 간호윤리학 방법론;통합된 사례방법론 (An integrated Method of New Casuistry and Specified Principlism as Nursing Ethics Methodology)

  • The purpose of the study was to introduce an integrated approach of new Casuistry and specified principlism in resolving ethical problems and studying nursing ethics. In studying clinical ethics and nursing ethics, there is no systematic research method. While nurses often experience ethical dilemmas in practice, much of previous research on nursing ethics has focused merely on describing the existing problems. In addition, ethists presented theoretical analysis and critics rather than providing the specific problems solving strategies. There is a need in clinical situations for an integrated method which can provide the objective description for existing problem situations as well as specific problem solving methods. We inherit two distinct ways of discussing ethical issues. One of these frames these issues in terms of principles, rules, and other general ideas; the other focuses on the specific features of particular kinds of moral cases. In the first way general ethical rules relate to specific moral cases in a theoretical manner, with universal rules serving as "axioms" from which particular moral judgments are deduced as theorems. In the seconds, this relation is frankly practical. with general moral rules serving as "maxims", which can be fully understood only in terms of the paradigmatic cases that define their meaning and force. Theoretical arguments are structured in ways that free them from any dependence on the circumstances of their presentation and ensure them a validity of a kind that is not affected by the practical context of use. In formal arguments particular conclusions are deduced from("entailed by") the initial axioms or universal principles that are the apex of the argument. So the truth or certainty that attaches to those axioms flows downward to the specific instances to be "proved". In the language of formal logic, the axioms are major premises, the facts that specify the present instance are minor premises, and the conclusion to be "proved" is deduced (follows necessarily) from the initial presises. Practical arguments, by contrast, involve a wider range of factors than formal deductions and are read with an eye to their occasion of use. Instead of aiming at strict entailments, they draw on the outcomes of previous experience, carrying over the procedures used to resolve earlier problems and reapply them in new problmatic situations. Practical arguments depend for their power on how closely the present circumstances resemble those of the earlier precedent cases for which this particular type of argument was originally devised. So. in practical arguments, the truths and certitudes established in the precedent cases pass sideways, so as to provide "resolutions" of later problems. In the language of rational analysis, the facts of the present case define the gounds on which any resolution must be based; the general considerations that carried wight in similar situations provide warrants that help settle future cases. So the resolution of any problem holds good presumptively; its strengh depends on the similarities between the present case and the prededents; and its soundness can be challenged (or rebutted) in situations that are recognized ans exceptional. Jonsen & Toulmin (1988), and Jonsen (1991) introduce New Casuistry as a practical method. The oxford English Dictionary defines casuistry quite accurately as "that part of ethics which resolves cases of conscience, applying the general rules of religion and morality to particular instances in which circumstances alter cases or in which there appears to be a conflict of duties." They modified the casuistry of the medieval ages to use in clinical situations which is characterized by "the typology of cases and the analogy as an inference method". A case is the unit of analysis. The structure of case was made with interaction of situation and moral rules. The situation is what surrounds or stands around. The moral rule is the essence of case. The analogy can be objective because "the grounds, the warrants, the theoretical backing, the modal qualifiers" are identified in the cases. The specified principlism was the method that Degrazia (1992) integrated the principlism and the specification introduced by Richardson (1990). In this method, the principle is specified by adding information about limitations of the scope and restricting the range of the principle. This should be substantive qualifications. The integrated method is an combination of the New Casuistry and the specified principlism. For example, the study was "Ethical problems experienced by nurses in the care of terminally ill patients"(Um, 1994). A semi-structured in-depth interview was conducted for fifteen nurses who mainly took care of terminally ill patients. The first stage, twenty one cases were identified as relevant to the topic, and then were classified to four types of problems. For instance, one of these types was the patient's refusal of care. The second stage, the ethical problems in the case were defined, and then the case was analyzed. This was to analyze the reasons, the ethical values, and the related ethical principles in the cases. Then the interpretation was synthetically done by integration of the result of analysis and the situation. The third stage was the ordering phase of the cases, which was done according to the result of the interpretation and the common principles in the cases. The first two stages describe the methodology of new casuistry, and the final stage was for the methodology of the specified principlism. The common principles were the principle of autonomy and the principle of caring. The principle of autonomy was specified; when competent patients refused care, nurse should discontinue the care to respect for the patients' decision. The principle of caring was also specified; when the competent patients refused care, nurses should continue to provide the care in spite of the patients' refusal to preserve their life. These specification may lead the opposite behavior, which emphasizes the importance of nurse's will and intentions to make their decision in the clinical situations.

  • The supply chain management (SCM) systems have emerged as strong managerial tools for manufacturing firms in enhancing competitive strength. Despite of large investments in the SCM systems, many companies are not fully realizing the promised benefits from the systems. A review of literature on adoption, implementation and success factor of IOS (inter-organization systems), EDI (electronic data interchange) systems, shows that this issue has been examined from multiple theoretic perspectives. And many researchers have attempted to identify the factors which influence the success of system implementation. However, the existing studies have two drawbacks in revealing the determinants of systems implementation success. First, previous researches raise questions as to the appropriateness of research subjects selected. Most SCM systems are operating in the form of private industrial networks, where the participants of the systems consist of two distinct groups: focus companies and vendors. The focus companies are the primary actors in developing and operating the systems, while vendors are passive participants which are connected to the system in order to supply raw materials and parts to the focus companies. Under the circumstance, there are three ways in selecting the research subjects; focus companies only, vendors only, or two parties grouped together. It is hard to find researches that use the focus companies exclusively as the subjects probably due to the insufficient sample size for statistic analysis. Most researches have been conducted using the data collected from both groups. We argue that the SCM success factors cannot be correctly indentified in this case. The focus companies and the vendors are in different positions in many areas regarding the system implementation: firm size, managerial resources, bargaining power, organizational maturity, and etc. There are no obvious reasons to believe that the success factors of the two groups are identical. Grouping the two groups also raises questions on measuring the system success. The benefits from utilizing the systems may not be commonly distributed to the two groups. One group's benefits might be realized at the expenses of the other group considering the situation where vendors participating in SCM systems are under continuous pressures from the focus companies with respect to prices, quality, and delivery time. Therefore, by combining the system outcomes of both groups we cannot measure the system benefits obtained by each group correctly. Second, the measures of system success adopted in the previous researches have shortcoming in measuring the SCM success. User satisfaction, system utilization, and user attitudes toward the systems are most commonly used success measures in the existing studies. These measures have been developed as proxy variables in the studies of decision support systems (DSS) where the contribution of the systems to the organization performance is very difficult to measure. Unlike the DSS, the SCM systems have more specific goals, such as cost saving, inventory reduction, quality improvement, rapid time, and higher customer service. We maintain that more specific measures can be developed instead of proxy variables in order to measure the system benefits correctly. The purpose of this study is to find the determinants of SCM systems success in the perspective of vendor companies. In developing the research model, we have focused on selecting the success factors appropriate for the vendors through reviewing past researches and on developing more accurate success measures. The variables can be classified into following: technological, organizational, and environmental factors on the basis of TOE (Technology-Organization-Environment) framework. The model consists of three independent variables (competition intensity, top management support, and information system maturity), one mediating variable (collaboration), one moderating variable (government support), and a dependent variable (system success). The systems success measures have been developed to reflect the operational benefits of the SCM systems; improvement in planning and analysis capabilities, faster throughput, cost reduction, task integration, and improved product and customer service. The model has been validated using the survey data collected from 122 vendors participating in the SCM systems in Korea. To test for mediation, one should estimate the hierarchical regression analysis on the collaboration. And moderating effect analysis should estimate the moderated multiple regression, examines the effect of the government support. The result shows that information system maturity and top management support are the most important determinants of SCM system success. Supply chain technologies that standardize data formats and enhance information sharing may be adopted by supply chain leader organization because of the influence of focal company in the private industrial networks in order to streamline transactions and improve inter-organization communication. Specially, the need to develop and sustain an information system maturity will provide the focus and purpose to successfully overcome information system obstacles and resistance to innovation diffusion within the supply chain network organization. The support of top management will help focus efforts toward the realization of inter-organizational benefits and lend credibility to functional managers responsible for its implementation. The active involvement, vision, and direction of high level executives provide the impetus needed to sustain the implementation of SCM. The quality of collaboration relationships also is positively related to outcome variable. Collaboration variable is found to have a mediation effect between on influencing factors and implementation success. Higher levels of inter-organizational collaboration behaviors such as shared planning and flexibility in coordinating activities were found to be strongly linked to the vendors trust in the supply chain network. Government support moderates the effect of the IS maturity, competitive intensity, top management support on collaboration and implementation success of SCM. In general, the vendor companies face substantially greater risks in SCM implementation than the larger companies do because of severe constraints on financial and human resources and limited education on SCM systems. Besides resources, Vendors generally lack computer experience and do not have sufficient internal SCM expertise. For these reasons, government supports may establish requirements for firms doing business with the government or provide incentives to adopt, implementation SCM or practices. Government support provides significant improvements in implementation success of SCM when IS maturity, competitive intensity, top management support and collaboration are low. The environmental characteristic of competition intensity has no direct effect on vendor perspective of SCM system success. But, vendors facing above average competition intensity will have a greater need for changing technology. This suggests that companies trying to implement SCM systems should set up compatible supply chain networks and a high-quality collaboration relationship for implementation and performance.
