The What-If-Not strategy as proposed by Brown & Walter (1969) is one of the most effective strategies for problem posing. However, it has focused only on the aspect of algorithms for generating problems. The aim of this strategy and how it is used to accomplish the aim of the challenging phase are not clear. We need to clarify the aim of the What-If-Not strategy and to establish the process of the strategy for accomplishing the aim. The purpose of this article is to offer a new What-If-Not strategy by clarifying the aim of the challenging phase.

본 연구는 Davydov가 언급한 이론적 일반화가 구체적으로 어떻게 이루어지는지를 탐구하는 것을 목적으로 하며, 이를 위해 본질적 속성의 인식을 돕는 전략과, 이 전략을 통해 이루어지는 이론적 일반화의 과정을 제시하는 것을 연구문제로 설정하였다. 본질적 속성의 인식을 돕는 전략으로 WIOS를 제시하였다. WIOS는 일반화하려는 명제의 결론을 고정하여, 명제의 가정으로부터 추출한 여러 속성을 대상으로 WIO를 통해 결론에 영향을 미치는 속성과 그렇지 않는 속성의 인지를 통해 본질을 추출하는 전략이다. 한편, 이 전략을 통해 이루어지는 이론적 일반화의 과정을 '인지, WIOS, 일반화된 명제의 추측, 정당화, 본질적 속성에 대한 통찰'의 순으로 제시하였다. 그리고 WIOS를 통해 이루어지는 이론적 일반화의 과정을 중학교 교과서에 수록된 2가지 정리에 적용하여 보았으며, 이를 통해 이 전략의 과정이 이론적 일반화의 수행을 도울 수 있는 전략임을 확인해 보았다.

학교수학에서 학생들이 수동적으로 교수를 전달받는 상황에서 능동적이고 주체적인 입장이 될 수 있는 대안의 하나로 문제설정이 주목받게 되면서, 이에 관한 많은 연구가 활발하게 이루어져 왔다. 특히 Brown & Walter는 문제설정의 한 방법으로 What If Not 전략을 제시하였다. 이 전략에서는 문제를 설정하는 과정에서 속성의 변형은 불가피하게 이루어지며, 문제설정 후 그 문제의 풀이를 함으로써 문제설정 과정을 마무리 짓는다. 그런데 속성 간의 관련성에 대한 고려 없이 속성의 변형을 하게 되면 문제를 잘못 설정할 수 있다. 이러한 사실은 올바른 문제설정을 위해서는 속성들 간의 유기적 결합을 이끄는 관련성 인식이 매우 중요하다는 것을 시사한다. 그러나 문제설정에 관한 다수의 연구는 이에 대하여 주목하지 못한 것으로 생각된다. 이에 본 연구에서는 의미 분석이라는 활동을 추가하여 문제 속에 내재된 지식을 인식하여 올바른 문제를 설정할 수 있도록 도울 수 있는 문제설정 모형을 설계하고자 하였다. 그리고 의미 분석을 강조한 문제설정 모형을 하나의 예를 통해 구체화하여 보여주었으며, 이를 통해 모형의 의의를 살펴볼 수 있었다. 본 연구를 통해 학생들이 문제설정의 진정한 의미를 이해할 수 있는 기회를 갖게 되고, 능동적 학습자로 거듭날 수 있기를 기대한다.

This paper is concerned with the study of 'Knowledge Management', a paradigm of thought based on the idea that the future will be a knowledge-centered society. This paper also provides an overview of both 'what to manage' and 'how to manage' if an organization wants to develop in this environment. The process of 'Knowledge Management' begins with a decision. Presented with a myriad of information, of which we can't afford to obtain it all, what information is of value to the organization? Further, by systematically organizing not only the primary information but also that which was accumulated in the process, Knowledge Management is capable of suggesting a value-added plan of action. This research presents the necessary principles needed in order to successfully use Knowledge Management, specifically a harmony between the human and technological aspects. There cannot be a static solution to the problem, as the environment of the enterprise's problem is dynamic in nature. Throughout the process, the enterprise will constantly change its strategy and structure in order to adapt to variable knowledge, technology, strategy, regulations, consumer interest, etc... The essential constant of these problems is the importance of spending on education. Investments in educations help develope a infrastructure for Information Technology, the development of knowledge distribution strategies, and the creation of efficient Knowledge Management policy.

The future is complex and unpredictable. In particular, it is unlikely to occur, but once it occurs, no one knows how it will affect our society if X-event, which has a tremendous impact, is created. This study was conducted only in the climate field to offset the ripple effect of this X-event, and was conducted through in-depth interviews with experts from the Korea Army Research Center for Future & Innovation and the Army College. As a result, it was possible to explore what factors would trigger X-event from their discourse and what X-event would be newly created by spreading them to other fields. Starting with this study, if we accumulate the discourse of experts in various fields such as population, science and technology, as well as climate, and other fields other than the Army, we can predict X-event and offset the threats that may arise.

Sexual dysfunction is a relatively common adverse effect in the use of antidepressants. The sexual side effects may result in a lack of compliance with the prescribed antidepressants. The author reviewed the prevalence and updated treatment for the antidepressant-induced adverse effects focusing on sexual dysfunction. The incidence of sexual dysfunction is reported to exceed more than 50% especially with SSRIs. In order to obtain a quantified baseline and as an ongoing evaluation tool, clinicians may use some of the established questionnaires and validated instruments such as the Arizona Sexual Experience scale and Changes in Sexual Functioning Questionnaire. Clinicians should be aware that delayed ejaculation and orgasm, symptoms most frequently associated with antidepressants, are not usually associated with depression itself. Although many antidotes have been proposed, few have been subjected to double-blind trials. Some evidences have suggested that bupropion and buspiron may be the effective antidotes for SSRI induced sexual dysfunction. Additional trials will be requied to define what role, if any, bupropion and buspiron might have in the treatment of SSRI-induced sexual side effects. The available evidence is rather limited, with only small number of trials assessing each strategy. While further randomized data is awaited, for men with antidepressant induced erectile dysfunction, the addition of sidenafil or tadalafil may appear to be an effective strategy.

When an organization adopts new technology, performance through the technology is expected to be decided depending on attitudes of the members, in that technology produces performance only if the members zealously use it. Therefore, the members need to devote themselves to acquire and use the new technology. This attitude of members is called "IT acceptance will" (Ranarajan et al., 2005), and this research is to examine the effect of an individual's "IT acceptance will" on performance. Thus, this research analyzes what increases IT acceptance will and what effect IT acceptance will has on stress due to uncertainty of an organization-job complexity and role conflict- through new IT adoption. This research conducted a survey from July to September in 2009, targeting employees of government offices and public institutions in Kyunggi and Kyungnam provinces. Then, a total of 370 was collected and the final 344 was selected for our research analysis. As a result, this research found out that personal innovation and client orientation improved an individual's IT acceptance will, which improved performance through new IT adoption. However, the new IT adoption also increased job complexity and role conflict, but negative effects of stress on performance was not found as IT adoption will diminished the stress. Based on this result, this research discussed practical and academic implications and the limitations.

Purpose - The movie market has the characteristics of being a perfectly competitive market as well as a pure monopolistic market at the same time. This is because there are competitors in the industry but prices, although not fixed, have not changed a lot. Price competition may not have spread, but the competition is focused on artistic value, and the degree of box office success is most important. The artistic value is determined in the course of the production process. However, the degree of box office success is dependent upon the marketing manager. The marketing strategy represents the difference in the standard or quality of the movie. Inherently, the marketing manager adopts the entertainment strategy based on the quality of the foundation of the completed movie. At this time, the marketing manager knows the pertinent information (high quality/low quality) regarding the movie. This research study tries to reveal what should be the reasonable movie marketing expense, dependent on the quality of the movie. Research design, data, and methodology - Using a game scenario with different market players, the goal of the research analysis is to find out the following. First, the marketing expense is determined to maximize the profits after film production. Second, after the production costs are already committed, the manufacturer gets to choose the marketing level. At this time, there will be a profit maximization point, considering the competition. The premise of the research is as follows: if it is a good movie of quality, positive word of mouth increasing the audience continuously slows down the speed of the demand curve. If the movie quality is bad, the negative word of mouth decreasing the audience gradually hastens the speed of the demand curve. On the marketing side, when the manufacturer invests heavily in the marketing expense of the movie, consumer expectations increase to drive up the audience numbers. On the other hand, it is difficult to improve the profits excessively. When the manufacturer invests in marketing a little bit, the marketing expense is only relatively committed, therefore a lot of demand cannot be gained. Results - If a fixed market share is in a competitive situation, a low quality manufacturer expends relatively more marketing expense. If the situation assumes two manufacturers spend the same for the cost of production, the high quality manufacturer takes more profit. If the manufacturer expends less marketing budget to save costs, the optimum profit cannot be achieved since the other party (opponent) grabs the initial market share. Conclusions - In conclusion, investment is essential for market share to increase. We must refrain from a zero-sum game and have models where the game participants pursue the creative profits together. In the current film industry, there is the dominating logic of winner and loser but we have to create a film industry environment where the participants can be altogether satisfied and live together.

This paper tried to examine the effect of the policy on companies' CSR activities and what kind of a role does CSR have in determining Customer Loyalty in Indonesia. This paper is divided into two parts, the first part is designed to find out whether the Indonesian government law has successfully made the companies perform better CSRs. We do this by using the ICGC Index of the companies registered and comparing their scores before and after the implementation of the policy. We will then use the paired sample t-test to find out if there is an increase in the overall scores of the companies and/or only the natural resource-related companies. The result showed an upward trend in the ICGC scores for all the companies which the Indonesian government law is intended to. In the second part, Manfred Schwaiger's components and parameters of corporate reputation was referred and used on Indonesian customers. We asked participants whether they think natural resource-related companies perform better CSRs and then we also tried to find out what factors really affect their loyalty towards companies or brands by conducting Multiple Regression Analysis. From the 4 factors that we have prepared, which consist of Performance, CSR, Quality and Attractiveness, Quality is the most influential towards determining our survey participants' Customer Loyalty. Surprisingly, CSR is insignificant in directly influencing Customer Loyalty. But, our research did find out that CSR does moderate Quality and Performance in their relationship with Customer Loyalty. Meaning that CSR has no effect in a direct relationship but it can increase the effect of Quality and Performance in determining Customer Loyalty. Unfortunately, CSR has no moderating effect in increasing the effect of Attractiveness towards Customer Loyalty.
