The research reviews the logical approach based on the creative thoughts. The two logical approaches, including deductive convergent and inductive divergent are discussed with why-why techniques and how-how techniques. While the deductive thinking is vertical logic for interconnected hierarchical and deep domains, the inducive thinking is horizontal logic for mutually exclusive and collectively exhausted frameworks. The creative thinking comes from the reversing the logic and lessening the premise of convergent and divergent approaches.

What was the reason why Apple, a mere "rookie", got ahead of all the veterans before it? What influence will the newly released Ipad have? This writing will cover why people are clamoring over Iphones and Ipads. In addition, it will also discuss if Apple will be able to challenge Google's dominance on the web world using Ipods, Iphones, Ipads as weapons.

The present study investigated why students do not like math using deep-level interview method. The reasons of why students dislike math were classified into three： socio-cultural, and individual factors, and math itself. Socio-cultural factors include the environments where students are reared, family, and school culture. Individual factors mean competitive disposition, preconception of math, active disposition, and conflicts with friends or teachers. Finally, students seem to dislike math because math itself is a difficult subject. In addition, textbook and instruction are also difficult, or they are lack of fundamental math knowledge. There may be other reasons of why students do not like math subject. In spite of those reasons, there should be some efforts to analyze why students dislike math and to help the students have interests in math.

Purpose: Looking for the root cause of a construction accident leads to the problem of unreasonable construction costs and air setting by the person placing an order. In addition, low-cost bidding by a contractor with insufficient capacity is combined, creating an inappropriate construction structure that can cause an accident before the start of construction. Method: Analysis of the problem that the lack of original contractor resources in the construction environment is passed on to suppliers, and the phenomenon that partners and their workers are forced to push ahead with excessive work to secure a minimum margin. Result: Going back to the root of construction accidents, there are several dimensions of causes from physical phenomena to root causes, but the reason why accident prevention measures so far remain almost at the one-dimensional level of responding to the phenomenon is the lack of fundamental cause analysis. Conclusion: It is necessary to shift the paradigm to safety accident measures led by the client (the client) and the government, and construction accidents are reduced only when root cause of construction accidents is found through fundamental cause analysis techniques such as 5Why.

수리 논리 기반의 프로그램 증명방법은 매우 유용한 프로그램 분석방법이지만, 수리 논리식에 대한 증명을 사람이 직접 수행하는 것은 매우 힘들고 고된 작업이다. 본고에서는 이러한 수리 논리 기반의 프로그램 증명을 자동화하기 위하여 개발된 중간 증명 언어(Intermediate Verification Language)에 대하여 살펴보고자 한다.

This paper aims to summarize why I write, how to find a motif, and how to polish and finish a manuscript. For William Carlos Williams, practicing medicine and writing poetry were two parts of a single whole, not each of the other. The two complemented each other. Medicine stimulated Williams to become a poet, while poetry was also the driving force behind his role as a doctor. Alexander Pope, the 18th century English poet, wrote a poem entitled "The Epistle to Dr. Arbuthnot" that was dedicated to a friend who was both a poet and a physician. In this poem, we receive an answer to the questions of "Why do you write? Why do you publish?" Pope writes, "Happy my studies, when by these approv'd! / Happier their author, when by these belov'd! / From these the world will judge of men and books." When I write, I first reflect on whether I only want to write something for its own sake, like "a dog chasing its own tail," instead of making a more worthwhile contribution. When my colleagues ask me, "Why do you write essays as well as scientific papers?" I usually answer, "Writing is a process of healing for me-I cannot bear myself unless I write." When the time comes to sit down and put pen to paper, I remind myself of the saying, festina lente (in German, Ohne Hast, aber ohne Rast, corresponding to the English proverb "more haste, less speed"). If I am utterly exhausted when I finish writing, then I know that I have had my vision.

This study aims to examine and develop a Triple Helix model for social innovation to eradicate pervasive poverty in developing countries. To do this, this study explores and analyzes the Rural Saemaul Undong (RSU), a rural community development movement for eradicating poverty that was driven by the South Korean government during the 1970s. First of all, this study explores the characteristics of the RSU and explains why the RSU was a social innovation. To support and explain why the RSU was a successful social innovation, this study analyzes the roles and activities of three distinct actor groups: the chief policymaker and his aides who presented the vision and purpose, or the "why" of the Saemaul Undong; central and local government officials who were the planners and managers who showed "how" to plan and drive it; and village Saemaul leaders as the drivers and coaches showing rural villagers "what" to do. Based on this analysis, this study develops an actor-based Triple Helix model for social innovation to eradicate poverty.

Previous studies present the mixed results on online reputation mechanism. In this study, we have found that an approach based on Bayesian statistics can explain most results of previous studies which are conflicting with each others. With this model, we explain why negative ratings have more significant marginal impacts on sellers' reputation than positive ones do. Furthermore, we even show why the feedbacks with a few negative ratings may increase the value of the item and final prices by confirming buyers' prior beliefs on the sellers' reputation much more than those without negative ratings. Also, we explain why there are not many negative ratings. Even though some studies suggest this because of generosity of users, our model shows that the reason is that the existence of FS itself prevents bad sellers from participating to the market as a signal itself. Even further, we show how this extreme tendency of positive ratings gets even stronger as markets evolve. Finally, to validate our analytical results, we examine the previous studies and see what factors effect the outcomes of their analyses.

We have explored the five-element pattern of "River Table(河圖)" in the "Naegyeong(內經)", and conclude that this pattern is one of the five-element patterns applied in the "Naegyeong". Based on this pattern, we can exactly understand the eum(陰) and yang(陽) range of five Jang-organs, why the spleen is the extreme eum, why the spleen is the isolated Jang, how the spleen governs four seasons, the ascending and descending of visceral gi(氣), as well as why it can be applied in clinic that the spleen and stomach are the pivot of the ascending and descending of visceral gi(氣).

In this study, we suggest implications for teaching mathematical justification with analysis of 6th grade students' awareness of why they needed mathematical justification and their levels of mathematics justification in Algebra and Geometry. Also how their levels of mathematical justification were related to mathematic achievement. 96% of students thought mathematical justification was needed, the reasons were limited for checking their solutions and answers. The level of mathematical justification in Algebra was higher than in Geometry. Students who had higher mathematic achievement had higher levels of mathematical justification. In conclusion, we searched the possibility of teaching mathematical justification to students, and we found some practical methods for teaching.
