By inputting consumer satisfaction as an exogenous variable into the value-based adoption model, this study explored the factors that influence the user's intention to continue using image-centered generative AI. Briefly presenting the main results, first, enjoyment did not significantly affect perceived value, but usefulness had a positive effect on perceived value. Second, Fee and technicality had a negative effect on perceived value. Third, perceived value had a positive effect on consumer satisfaction and continuous use intention. Fourth, consumer satisfaction had a positive effect on continuous use intention. Based on the above results, it is important to recognize the usefulness of image-centered generated AI and enjoyment in the process of use in order to increase the user's intention to continue using image-centered generated AI, and at the same time, it will be important to increase the user's perceived value and satisfaction by minimizing the reasonable fee and complexity in the method of use at the level acceptable to the users.

주어진 계획 문제로부터 휴리스틱을 이용하여 최적의 해 계획을 구하기 위해서는 허용 가능한 휴리스틱을 이용하여야 한다. 이러한 허용 가능한 휴리스틱은 실제 목표 도달거리보다 짧거나 같아야 하는데 휴리스틱 평가치가 실제 목표 도달거리에 가까울수록 계획생성을 위한 탐색 효율성이 높아진다. 하지만, 이러한 허용 가능한 휴리스틱 평가치를 구하는 과정은 매우 복잡하며 계산량이 많기 때문에 실제 계획 생성 과정에서 사용하기는 어렵다. 때문에 최대 휴리스틱과 같은 허용성을 만족하는 간단한 휴리스틱을 이용하고 있으며, 이로 인해 최적의 계획 결과를 얻을 수는 있지만, 탐색의 효율성이 떨어지는 결과를 가져오고 있다. 본 논문에서는 이러한 문제를 해결하기 위해서 기존의 계획그래프를 개선한 새로운 계획그래프인 확장된 계획그래프(EPG)를 이용한 MAX+ 휴리스틱 계산법을 소개한다. 확장된 계획그래프는 계획 문제 풀이를 위한 휴리스틱 계산에 이용되는 기존의 간략화된 계획그래프를 목표조건들 간의 상호작용을 확인 할 수 있도록 확장한 자료구조로써 목표조건들 간의 긍정적/부정적 상호작용을 찾는다. 이를 위해서 모든 목표조건들이 등장할 때까지 그래프를 전개하는 기본 전개 과정과 함께, 이 과정에서 발견된 동작과 목표 조건들과의 관계를 바탕으로 한 추가 전개 과정으로 이루어져 있다. 그리고 이 과정을 통해서 목표조건들간의 상호작용과 최단 거리를 구하게 된다. MAX+ 휴리스틱 계산에서는 이러한 목표조건들 간의 긍정적/부정적 상호작용의 존재 유무를 찾아내게 됨으로써 전체 목표 집합에 대한 보다 정확한 최소 도달거리에 대한 평가치를 찾게 된다. 따라서 MAX+ 휴리스틱은 기존의 최대 휴리스틱 보다 더 정보력 높은 휴리스틱을 구할 수 있는 장점이 있다. 본 논문에서는 MAX+ 휴리스틱의 계산 과정과 MAX+ 휴리스틱의 정확성과 이를 바탕으로 한 탐색 효율성을 확인하기 위한 실험적 분석에 대해 설명한다.

This study explored the simulation of film in the post-modern society through Jean Baudrillard's theory of simulation. The 21st century can be said to be in a simulated world in which representational images dominate and can be said to be the era of images, where reality and imagination cannot be distinguished. In this world, movies are created under the premise of 'fictional' as a work of art created by man, but in the present post-modern society, the audience responds to and ignores the movie according to the expression of this simulation. In this aspect, we looked at the trends according to the expression method of Simulation, and found that successful film works express the cold reality in various and diverse ways and express it with positive 'stimulating' elements. Through this, in order to develop more deeply and systematically in the production of domestic films, various humanistic values, which are double tracks that can systematically compose a simulation that contains a didactic message about the real world and draw the audience's response, It was concluded that an attempt to express 'stimulating' in a positive sense was necessary.

Globalization has been accelerated in today's business environment. In this situation, the opening of economies can be either an opportunity or a treat for small and medium sized enterprises (SMEs) who have limited resources. Especially, managerial perception to the opening of economies carries on significant meaning because managerial perception determines future responses and strategies. Therefore, this study examined which innovation activities are related with SMEs' positive perception to the opening of economies. The activities of innovation are classified by types of generic strategy. Also, this study scrutinized the moderating effects of external search strategy and market entry strategy. In order to test hypotheses, this study analyzed data on Korean manufacturing firms collected in the Korean Innovation Survey (KIS). As a result, SMEs conducting innovation for differentiation strategy perceived the opening of economies positively. Search breadth and search depth moderated this relationship negatively and the first entry strategy moderated this relationship positively.
