이 연구는 기독교교육의 성찰을 위해 보드리야르(J. Baudrillard)의 중요개념인 시뮬라시옹(Simulation)과 시뮬라크르(Simulacra) 등을 중심으로 포스트 코로나 시대의 한 단면을 분석할 수 있는 드라마 「펜트하우스」의 소비이데올로기, 이미지의 욕망 및 폭력 등에 관해 검토할 것이다. 보드리야르는 시뮬라시옹 개념이 대중매체의 발전에서 생겨났다고 보고, 대중매체는 결국 실재를 사라지게 하는 '시뮬라시옹의 출현' 혹은 '시뮬라시옹의 과정'이라고 설명한다. 보드리야르는 시뮬라시옹 과정이 대중매체가 지배하는 소비사회의 다양한 영역에서 진행되고 있다는 것을 지적한다. 시뮬라시옹은 이미지에 의해 실재보다 더 실재적인 초과실재를 산출하는 과정이며, 시뮬라크르는 시뮬라시옹의 결과이다. 포스트 코로나 시대의 기독교교육은 비판이론을 통한 비판적 성찰의 준거 기준이 합의 되지 않았다는 부정적 측면으로 인해 거부하지 말고 비판이론의 긍정적 입장을 고려해야 한다. 다시 말해서 대중매체가 주도하는 지배이데올로기와 소비이데올로기의 속성을 봐야한다. 특히 광고나 드라마 영화에서 보여주는 메시지는 시뮬라크르만 남아 실제보다 더 실제 같은 허상임을 보는 관점을 지녀야 한다. 미디어는 말을 하되 상대방의 응답이 이루어질 수 없게 만드는 미디어의 권력을 의미한다. 그것의 대표적인 예표가 텔레비전이며, 연구자가 드라마 「펜트하우스」를 분석하는 이유이기도 하다. 보드리야르는 맥루한(M. McLuhan)의 "미디어가 메시지다"(The medium is the message)라는 명제는 예상치 못하게 모든 내용물과 메시지가 미디어 속으로 사라져 버린 뒤에, 미디어 자신도 증발해 버린다고 지적한다. 그러나 기독교교육은 "하나님 말씀이 메시지"(The word of God is message)임을 가르치고, 배우고, 나누고, 전수하는 것이다. 또한 그 메시지는 내파되거나 함열되는 것이 아니라 영원한 진리로 계속 살아있는 메시지이다. 위기와 불안의 포스트 코로나 시대의 기독교교육은 사회 현상과 관련하여 대중/소비자/교인 개체들을 무저항적이고 무비판적으로 만드는 소비지상주의의 소비문화에 관해 끊임없는 성찰의 장(場)을 마련하고, 일련의 '전망대'의 역할을 감당해야 할 것이다.

이 논문은 다변화하고 있는 환경미학의 최근 전개 양상을 고찰하고, 환경미학의 중요한 갈래로 부상하고 있는 일상미학의 주요 의제와 주장, 쟁점과 의의를 비판적으로 검토한다. 1960년대의 문화 변동과 환경주의를 바탕으로 싹튼 환경미학은 20세기 후반 이론적 기반을 다지며 성장했고, 21세기에 들어서면서 대상과 주제의 다변화 과정에 진입했다. 학문적 성숙기를 맞은 환경미학은 도시를 포함한 인문환경 전반으로 이론적 영토를 확장했으며, 도시 환경과 경관의 계획·설계 담론으로서 실천적 좌표를 제시했다. 특히 2000년대 중반 이후 환경미학의 가장 주목할 성과는 '일상미학'의 성립이라고 할 수 있다. 일상미학 연구를 주도하고 있는 유리코 사이토는 미학 이론의 대상과 범위를 일상의 사물, 사건, 행동, 환경으로 확장한다. 그는 기존의 예술 중심적 미학이 간과해온 일상의 미시적이고 감각적인 국면을 미학의 시선으로 발굴해 현대 도시의 환경과 경관, 공간과 장소에서 벌어지는 현상의 다양한 층위를 새롭게 해석하며, 일상에 숨겨진 '미적인 것의 힘'이 삶의 질과 세상의 상태에 미치는 심대한 영향을 분석한다. 그는 일상의 대상과 환경에 내재한 특유의 성질과 분위기에 대한 감상을 고찰하고, 일상의 미적 감상과 판단이 낳는 환경적, 사회적, 정치적 결과를 경계하기 위해 '도덕적-미적 판단'을 제안한다. 이 논문은 일상미학의 쟁점과 의의를 첫째 미학의 확장과 모호한 일상, 둘째 도덕적-미적 판단과 돌봄의 미학, 셋째 도시 재생 경관과 미학적 문해력으로 파악한다. 특히 사이토가 주장하는 일상미학의 도덕적 덕목, 즉 돌봄, 사려 깊음, 감수성, 존중 등은 동시대 도시재생 경관의 실천에 대한 비평적 준거를 마련해준다. 그가 강조하는 '미학적 문해력'은 일상의 도시 환경과 경관 해석에 환경미학의 관점이 필요한 이유를 입증하는 핵심 개념이다.

20世纪60年代中期, 随着1967年 ${\ll}$产业购买和创造营销${\gg}$的出版, 组织购买行为这一领域的兴起为企业如何在市场中运作提供了新的思维方式, 而不只是为最终用户服务. 无论是 "工业营销" 或 "企业营销"(B-to-B),组织的购买行为仍然是这个领域的核心. 本文探讨了动态因素的影响,影响了几个组织彼此相关的迅速增长的相互依存,反过来会影响组织的购买行为. 文章还提出了一个问题,组织购买行为的概念模型,在一个相互依存的世界是否仍然会在这个充满活力的经营环境中引导研究和管理的思想,. 本文提出并探索三个关于组织相互依存的问题: 1.哪些因素和趋势驱动了组织的相互依存的兴起? 2.在过去半个世纪中发展起来的组织购买行为的主要概念模型仍然适用于今天这个相互依存的组织的世界吗? 3.研究中组织的相互依存的启示是什么? 组织购买行为的实践活动是什么? 考虑到组织关系中驱动组织的相互依存的因素和趋势和5个关键驱动因素有关并影响他们的购买行为:加速全球化, 平整的网络组织, 破坏价值链, 强化政府的介入, 不断细分客户需求. 这五个相通的相互依存和潜在的技术上的优势可以改变组织购买产品和服务的市场中保持竞争力的关系. 在一个客户驱动的营销策略背景下, 这些力量影响三个层次的战略发展: (1)进化的客户需求, (2)产生的产品/服务和解决方案以满足这些需求, 和(3)的组织能力和工艺制定和实施了以满足需求. 组织中相互依存的五个驱动因素在他们影响组织如何购买时不需要独立的操作. 他们可以相互作用和更加有效的影响组织购买行为. 例如,加速了全球化的影响,出现了新的网络进一步破坏传统价值链之间的关系, 从而改变机构购买的产品和服务. 提高政府参与可能会增加成本,因此在其它国家的新兴市场开公司做生意寻求低成本的来源. 这可以减少一国的就业机会增加另一个国家的就业机会, 在另一方面, 从而进一步加速全球化. 第二个主要的问题是相互依存的五个驱动因素对组织购买行为的核心概念模型有什么影响. 考虑三个在 ${\ll}$产业购买和创造营销${\gg}$ 和 ${\ll}$组织购买行为${\gg}$ 书籍中发展的概念模型:组织购买过程, 购买中心,以及购买的情况. 回顾这些核心模型, 作为最初的概念,他们仍然是有效的, 而且不可能改变. 在买家和卖家相互依赖的情况下, 什么会改变买卖双方相互作用的方式. 例如,增加了相互依赖的机会可能导致增加协作以及组织之间的冲突的买卖,从而改变购买过程. 此外,组织中的沟通过程的重要性作为一个成功的购买关系的判断依据将增加. 第三个问题对这些组织购买行为的关系的影响和意义进行了探讨. 以下是本文所考虑到的: 为了增进对网络对组织购买行为的影响的理解,需要增加了解所扮演的角色之间的信任, 增强在网络环境中如何管理组织购买的理解的需要, 需要增加了解在价值网络中的客户需要,并且需要增加了解新兴的商业模式对组织购买行为的影响. 在许多方面,这些从增加的组织的相互依存派生出来的需要是组织购买行为传统概念的扩展. 在1977年,Nicosia 和Wind建议把焦点集中在组织间而不是组织内部观点,自1990年以来, 这个趋势的势头很强. 对于管理者来说,也想在越来越相互依存的世界中生存,他们将需要更好地了解组织如何与另一组织相关的复杂性. 从组织的相互依存的观点已经开始,必须不断地发展提出一种对这些重要的关系改进的理解. 互相依赖的网络观点的转变需要很多学术界人士和实践者从根本上挑战和改变他们商业中的心智模型和组织购买行为模型. 不再只关注购买组织和销售组织之间的关系而应该是网络中所有的相关成员, 包括消费者, 发展者, 供应商和中间者. 我们来看这个例子. 由SAP创造的有众多合作伙伴的网络包含了超过9000个公司和超过一百万的参与者. 互相依赖的进展, 复杂性和不确定的现实和多变的网络需要重新考虑如何做出购买决定. 结果是他们应该关注学术中下一阶段的研究和理论建设并关注有实践者构建的实践模型和实验. 我们希望这样的研究能够展开, 不是孤立在象牙塔里, 也不是限制在商业世界中, 而是学术和实践的结合. 总而言之, 组织之间相互依赖的提高的考虑揭示了组织购买行为的基础模型的持续关联性. 然而在相互依存的世界中来提高这些模型的价值, 学术界和实践者应该提高他们对一下内容的理解 (1)网络的影响; (2)如何更好地管理这些影响的作用; (3)组织之间信任和价值的作用, (4)价值网络中客户需求的演变; (5)组织购买行为的新兴的新商业模型的影响. 为了实现这一目标, 我们需要产业界和学习界更好的合作从而提高我们对在相互依赖的世界中的组织购买行为的理解.

Due to the increasing and intensifying competition in the Internet shopping market, it has been recognized as very important to develop an effective policy and strategy for acquiring loyal customers. For this reason, web site designers need to know if a new Internet shopping mall(ISM) will be accepted. Researchers have been working on identifying factors for explaining and predicting user acceptance of an ISM. Some studies, however, revealed inconsistent findings on the antecedents of user acceptance of a website. Lack of consideration for individual differences in user ability is believed to be one of the key reasons for the mixed findings. The elaboration likelihood model (ELM) and several studies have suggested that individual differences in ability plays an moderating role on the relationship between the antecedents and user acceptance. Despite the critical role of user ability, little research has examined the role of user ability in the Internet shopping mall context. The purpose of this study is to develop a user acceptance model that consider the moderating role of user ability in the context of Internet shopping. This study was initiated to see the ability of the technology acceptance model(TAM) to explain the acceptance of a specific ISM. According to TAM. which is one of the most influential models for explaining user acceptance of IT, an intention to use IT is determined by usefulness and ease of use. Given that interaction between user and website takes place through web interface, the decisions to accept and continue using an ISM depend on these beliefs. However, TAM neglects to consider the fact that many users would not stick to an ISM until they trust it although they may think it useful and easy to use. The importance of trust for user acceptance of ISM has been raised by the relational views. The relational view emphasizes the trust-building process between the user and ISM, and user's trust on the website is a major determinant of user acceptance. The proposed model extends and integrates the TAM and relational views on user acceptance of ISM by incorporating usefulness, ease of use, and trust. User acceptance is defined as a user's intention to reuse a specific ISM. And user ability is introduced into the model as moderating variable. Here, the user ability is defined as a degree of experiences, knowledge and skills regarding Internet shopping sites. The research model proposes that the ease of use, usefulness and trust of ISM are key determinants of user acceptance. In addition, this paper hypothesizes that the effects of the antecedents(i.e., ease of use, usefulness, and trust) on user acceptance may differ among users. In particular, this paper proposes a moderating effect of a user's ability on the relationship between antecedents with user's intention to reuse. The research model with eleven hypotheses was derived and tested through a survey that involved 470 university students. For each research variable, this paper used measurement items recognized for reliability and widely used in previous research. We slightly modified some items proper to the research context. The reliability and validity of the research variables were tested using the Crobnach's alpha and internal consistency reliability (ICR) values, standard factor loadings of the confirmative factor analysis, and average variance extracted (AVE) values. A LISREL method was used to test the suitability of the research model and its relating six hypotheses. Key findings of the results are summarized in the following. First, TAM's two constructs, ease of use and usefulness directly affect user acceptance. In addition, ease of use indirectly influences user acceptance by affecting trust. This implies that users tend to trust a shopping site and visit repeatedly when they perceive a specific ISM easy to use. Accordingly, designing a shopping site that allows users to navigate with heuristic and minimal clicks for finding information and products within the site is important for improving the site's trust and acceptance. Usefulness, however, was not found to influence trust. Second, among the three belief constructs(ease of use, usefulness, and trust), trust was empirically supported as the most important determinants of user acceptance. This implies that users require trustworthiness from an Internet shopping site to be repeat visitors of an ISM. Providing a sense of safety and eliminating the anxiety of online shoppers in relation to privacy, security, delivery, and product returns are critically important conditions for acquiring repeat visitors. Hence, in addition to usefulness and ease of use as in TAM, trust should be a fundamental determinants of user acceptance in the context of internet shopping. Third, the user's ability on using an Internet shopping site played a moderating role. For users with low ability, ease of use was found to be a more important factors in deciding to reuse the shopping mall, whereas usefulness and trust had more effects on users with high ability. Applying the EML theory to these findings, we can suggest that experienced and knowledgeable ISM users tend to elaborate on such usefulness aspects as efficient and effective shopping performance and trust factors as ability, benevolence, integrity, and predictability of a shopping site before they become repeat visitors of the site. In contrast, novice users tend to rely on the low elaborating features, such as the perceived ease of use. The existence of moderating effects suggests the fact that different individuals evaluate an ISM from different perspectives. The expert users are more interested in the outcome of the visit(usefulness) and trustworthiness(trust) than those novice visitors. The latter evaluate the ISM in a more superficial manner focusing on the novelty of the site and on other instrumental beliefs(ease of use). This is consistent with the insights proposed by the Heuristic-Systematic model. According to the Heuristic-Systematic model. a users act on the principle of minimum effort. Thus, the user considers an ISM heuristically, focusing on those aspects that are easy to process and evaluate(ease of use). When the user has sufficient experience and skills, the user will change to systematic processing, where they will evaluate more complex aspects of the site(its usefulness and trustworthiness). This implies that an ISM has to provide a minimum level of ease of use to make it possible for a user to evaluate its usefulness and trustworthiness. Ease of use is a necessary but not sufficient condition for the acceptance and use of an ISM. Overall, the empirical results generally support the proposed model and identify the moderating effect of the effects of user ability. More detailed interpretations and implications of the findings are discussed. The limitations of this study are also discussed to provide directions for future research.

Fuzzy logic based Control Theory has gained much interest in the industrial world, thanks to its ability to formalize and solve in a very natural way many problems that are very difficult to quantify at an analytical level. This paper shows a solution for treating membership function inside hardware circuits. The proposed hardware structure optimizes the memoried size by using particular form of the vectorial representation. The process of memorizing fuzzy sets, i.e. their membership function, has always been one of the more problematic issues for the hardware implementation, due to the quite large memory space that is needed. To simplify such an implementation, it is commonly [1,2,8,9,10,11] used to limit the membership functions either to those having triangular or trapezoidal shape, or pre-definite shape. These kinds of functions are able to cover a large spectrum of applications with a limited usage of memory, since they can be memorized by specifying very few parameters ( ight, base, critical points, etc.). This however results in a loss of computational power due to computation on the medium points. A solution to this problem is obtained by discretizing the universe of discourse U, i.e. by fixing a finite number of points and memorizing the value of the membership functions on such points [3,10,14,15]. Such a solution provides a satisfying computational speed, a very high precision of definitions and gives the users the opportunity to choose membership functions of any shape. However, a significant memory waste can as well be registered. It is indeed possible that for each of the given fuzzy sets many elements of the universe of discourse have a membership value equal to zero. It has also been noticed that almost in all cases common points among fuzzy sets, i.e. points with non null membership values are very few. More specifically, in many applications, for each element u of U, there exists at most three fuzzy sets for which the membership value is ot null [3,5,6,7,12,13]. Our proposal is based on such hypotheses. Moreover, we use a technique that even though it does not restrict the shapes of membership functions, it reduces strongly the computational time for the membership values and optimizes the function memorization. In figure 1 it is represented a term set whose characteristics are common for fuzzy controllers and to which we will refer in the following. The above term set has a universe of discourse with 128 elements (so to have a good resolution), 8 fuzzy sets that describe the term set, 32 levels of discretization for the membership values. Clearly, the number of bits necessary for the given specifications are 5 for 32 truth levels, 3 for 8 membership functions and 7 for 128 levels of resolution. The memory depth is given by the dimension of the universe of the discourse (128 in our case) and it will be represented by the memory rows. The length of a world of memory is defined by: Length = nem (dm(m)＋dm(fm) Where: fm is the maximum number of non null values in every element of the universe of the discourse, dm(m) is the dimension of the values of the membership function m, dm(fm) is the dimension of the word to represent the index of the highest membership function. In our case then Length=24. The memory dimension is therefore 128*24 bits. If we had chosen to memorize all values of the membership functions we would have needed to memorize on each memory row the membership value of each element. Fuzzy sets word dimension is 8*5 bits. Therefore, the dimension of the memory would have been 128*40 bits. Coherently with our hypothesis, in fig. 1 each element of universe of the discourse has a non null membership value on at most three fuzzy sets. Focusing on the elements 32,64,96 of the universe of discourse, they will be memorized as follows: The computation of the rule weights is done by comparing those bits that represent the index of the membership function, with the word of the program memor . The output bus of the Program Memory (μCOD), is given as input a comparator (Combinatory Net). If the index is equal to the bus value then one of the non null weight derives from the rule and it is produced as output, otherwise the output is zero (fig. 2). It is clear, that the memory dimension of the antecedent is in this way reduced since only non null values are memorized. Moreover, the time performance of the system is equivalent to the performance of a system using vectorial memorization of all weights. The dimensioning of the word is influenced by some parameters of the input variable. The most important parameter is the maximum number membership functions (nfm) having a non null value in each element of the universe of discourse. From our study in the field of fuzzy system, we see that typically nfm 3 and there are at most 16 membership function. At any rate, such a value can be increased up to the physical dimensional limit of the antecedent memory. A less important role n the optimization process of the word dimension is played by the number of membership functions defined for each linguistic term. The table below shows the request word dimension as a function of such parameters and compares our proposed method with the method of vectorial memorization[10]. Summing up, the characteristics of our method are: Users are not restricted to membership functions with specific shapes. The number of the fuzzy sets and the resolution of the vertical axis have a very small influence in increasing memory space. Weight computations are done by combinatorial network and therefore the time performance of the system is equivalent to the one of the vectorial method. The number of non null membership values on any element of the universe of discourse is limited. Such a constraint is usually non very restrictive since many controllers obtain a good precision with only three non null weights. The method here briefly described has been adopted by our group in the design of an optimized version of the coprocessor described in [10].
