농약은 농산물 생산에 있어서 병해충 및 잡초를 방제함으로써 생산성을 높이는데 필수적인 농업자재로 인식하고 있다. 그런데 모든 화학물질이 그러하듯이 농약도 두 가지 양면성을 지니고 있다. 즉, 약효와 독성이다. 일반적으로 농약은 뿌려진 농약의 $0.1\%$이하만이 목표물이라고 할 수 있는 해충 및 잡초, 이병작물에 떨어지고 그 외는 비표적 생물 및 환경매체에 떨어짐으로써 생태계에 영향을 준다고 한다. 약효는 농약으로서 지녀야 하는 당연한 기능이지만 독성은 가능한 줄여야 할 기능이기 때문에 농약회사에서는 약효는 높으면서 사람과 생태계에는 좀 더 안전한 농약을 개발하기 위해 애쓰고 있다. 우리나라는 전세계적으로 볼 때 농약을 비교적 많이 사용하는 나라로 알려져 있으나 경제규모 및 사용량에 비해서 생태계에 대한 농약관리는 앞서가지 못하고 있는 것이 현실이다. 따라서 농약의 생태위해성 평가에 대한 기본적인 이해를 돕기 위해 이번호부터 연재를 통해 생태위해성에 대한 기본개념을 소개함과 동시에 국내외 농약등록제도에서의 생태위해성 의사결정 과정을 비교하고 마지막으로는 국내 농약관리제도에 있어서 생태독성분야의 의사결정에 대하여 개선방안을 제안하고자 한다.

Under the stiff competition in the health care industry, the long run survival of medical institution depends on building up customer loyalty. The purpose of this study is to figure out the influencing factors on customer loyalty. This new model is based on Bettman(1979)'s customer purchasing decision making process(awareness-interest-final decision). The key characteristics of this model reflects the psychological change of customer purchasing decision The influencing factor at each purchasing stage must need to be identified because the inner decision making process is generally carried out by multistage. In this respect, this study shows the brand awareness of hospital plays an important role at the first stage. In a second stage, the servciescape and service quality of hospital must be considered. Finally, customer's perceived value is adopted. By using a sample of 116 Chinese tourists, this study empirically examines the influencing factors of customer loyalty. The results that the brand awareness and perceived value have a positive effect on customer loyalty.

본 연구는 농산업 예비창업자를 대상으로 자기결정성정도를 조절변수로 하여 창업환경과 창업역량이 창업의도에 미치는 영향을 탐색하였다. 창업환경을 인지된지원과 인지된장벽으로 구분하고 창업역량의 하위변수를 창의성, 문제해결, 의사소통, 마케팅 및 사업계획서를 하위변수로 설정하였다. 수집된 설문지 253부를 실증분석에 사용하였다. SPSS v25.0과 Process macro v4.2를 이용한 분석결과는 첫째, 창업환경의 인지된지원과 인지된장벽은 창업의도에 유의한 영향을 미치고 창업역량의 창의성, 문제해결, 마케팅 및 사업계획서가 창업의도에 미치는 영향은 유의적으로 나타났으나 의사소통이 미치는 영향은 비유의적으로 나타났다. 둘째, 자기결정성정도는 창업환경의 인지돤지원 및 인지된장벽과 농산업 창업의도 간을 조절하지 않는 것으로 나타났다. 이 결과는 자기결정의 수준은 창업 환경과 창업 의도 사이의 관계에는 그다지 큰 영향을 미치지 않음을 의미한다. 셋째, 자기결정성정도는 창업역량의 창의성, 문제해결, 의사소통, 마케팅 및 사업계획서와 창업의도 간을 조절하는 것으로 확인되었다. 구체적으로 자기결정성정도가 커질수록 창의성, 문제해결, 마케팅 및 사업계획서가 창업의도에 미치는 영향력의 크기는 정(+)의 방향으로 강하게 하는 강화작용의 역할을 하는 것으로 나타났다. 반면에 자기결정성정도가 커질수록 의사소통과 창업의도 간의 관계가 약해지는 자기결정성정도가 완화작용을 하는 것으로 나타났다. 후속 연구로는 창업환경과 창업역량을 설명할 수 있는 다른 요인들의 탐색과 새로운 매개변수와 조절변수가 포함된 조건부과정모형을 통해 조절된 매개효과를 분석할 수 있는 후속 연구가 필요할 것으로 보인다.

Environmental impact assessment in the step of the Life Cycle Assessment (LCA) measures relative values of importance or weight of the environmental load characterized in the inventory analysis. The weight measurements are used to evaluate the environmental load or the effect of the industrial product or technology. In this paper the Analytic Network Prpcess (ANP) is introduced to calculate a relative weighting of the environmental impact. The ANP is considered as one of the useful decision making framework and allow for more complex interrelationships, feedback, and inner/outer dependence among the decision level and factors. The weighting from the ANP may applied to obtain the overall evaluation value of environmental load.

When a consumer intends to purchase products through Internet stores, many difficulties are met because of limitations of the current search engines and the current web structure, and lack of tools supporting decision-makings. This paper raises an Internet shopping problem and proposes a framework of decision making process to settle it with an intelligent agent based on Semantic Web and Finite Domain Constraint. The agent uses finite domain constraint programming as modeling and solution methods for the decision problem under the Semantic Web environment.

The purpose of this study was to investigate the effect of decision-making activities in lesson on improving decision-making ability to meet bioethical issues in everyday situation. Worksheet for decision-making was consisted of six steps: Identification of problem, searching relevant information, generation of alternatives, identification of values for selection criteria, evaluation of alternatives, review of consequence. The results of this study showed that the scores of decision-making were increased by the activities of worksheets. The scores of identification of problem, generation of alternatives, and evaluation of alternatives were increased meaningfully. However, the scores of searching relevant information, identification of values for selection criteria, and review of consequence were not increased. It seems that all steps of decision-making ability could not improve by short-term learning. Low level performance was appeared on the step of searching relevant information and evaluation of alternatives. This result indicated that students could not apply the biological knowledge to decision-making in the face of bioethical issues. In conclusion, the learning experience of decision-making is essential to foster rational decision-making ability. The activity of decision-making should be included in science class and curriculum.

As the implementation of smart factories spreads widely, the need for research to improve data efficiency is raised by prioritizing massive amounts of big data using IoT devices in terms of relevance and quality. The purpose of this study is to investigate whether prioritizing big data in management accounting decisions such as cost volatility estimation and recipe optimization can improve smart solution performance and decision-making effectiveness. Based on the survey answers of 84 decision makers at domestic small and medium-sized manufacturers who operate smart solutions such as ERP and MES that link manufacturing data in real time, empirical research was conducted. As a result, it was analyzed that setting prioritization of big data has a positive effect on decision-making in management accounting. became In addition, it was found that big data prioritization has a mediating effect that indirectly affects smart solution performance by using big data in management accounting decision making. Through the research results, it will be possible to contribute as a prior research to develop a scale to evaluate the correlation between big data in the process of business decision making.

The reduction of traffic accidents is a primary potential benefit of autonomous vehicles (AVs). However, the prevalence of AVs also arouses a key question: to what extent should a human wrest control back from AVs? Specifically, in an unavoidable situation of emergency, should an AV be able to decide between the safety of its own passengers and endangered pedestrians? Should AV programming include well-accepted decision rules about actionsto take in hypothetical situations? The current study (N = 103) examined individual/situational variables that could perform critical decision-making roles in AV related traffic accidents. The individual variable of attitudes toward AVs was assessed using the Self-driving Car Acceptance Scale. To investigate situational influences on decisional processes, the study's participants were assigned to one of two groups: the achievement value was activated in one group and the benevolence value was triggered in the other through the use of a sentence completion task. Thereafter, participants were required to indicate who should be protected from injury: the passengers of the concerned AV, or endangered pedestrians. Participants were also asked to record the extent to which they intended to buy an AV programmed to decide in favor of the greater good according to Utilitarian principles. The results suggested that participants in the "achievement value: driver perspective" groupexpressed the lowest willingness to sacrifice themselves to save several pedestrians in an unavoidable traffic accident. This group of participants was also the most reluctant to buy an AV programmed with utilitarian rules, even though there were significant positive relationships between members' acceptance of AVs and their expressed intention to purchase one. These findings highlight the role of the decisional processes involved in the "achievement value" pertaining to AVs. The paper finally records the limitations of the present study and suggests directions for future research.
