Data mining is the representative methodology to obtain meaningful information in the era of big data.By Wikipedia, association rule learning is a popular and well researched method for discovering interesting relationship between itemsets in large databases using association thresholds. It is intended to identify strong rules discovered in databases using different interestingness measures. Unlike general association rule, inverse association rule mining finds the rules that a special item does not occur if an item does not occur. If two types of association rule can be simultaneously considered, we can obtain the marketing information for some related products as well as the information of specific product marketing. In this paper, we propose a balanced attributable relative accuracy applicable to these association rule techniques, and then check the three conditions of interestingness measures by Piatetsky-Shapiro (1991). The comparative studies with rule accuracy, relative accuracy, attributable relative accuracy, and balanced attributable relative accuracy are shown by numerical example. The results show that balanced attributable relative accuracy is better than any other accuracy measures.

By Wikipedia, big data is a broad term for data sets so large or complex that traditional data processing applications are inadequate. Data mining is the computational process of discovering patterns in huge data sets involving methods at the intersection of association rule, decision tree, clustering, artificial intelligence, machine learning. Association rule is a well researched method for discovering interesting relationships between itemsets in huge databases and has been applied in various fields. There are positive, negative, and inverse association rules according to the direction of association. If you want to set the evaluation criteria of association rule, it may be desirable to consider three types of association rules at the same time. To this end, we proposed a balanced comparative confidence considering sensitivity, specificity, false positive, and false negative, checked the conditions for association threshold by Piatetsky-Shapiro, and compared it with comparative confidence and inversely comparative confidence through a few experiments.

디지털 영화의 핍진성은 인지적 균형과 밀접한 연관성을 가진다. 이것은 이미지를 통해 균형을 이루기 위한 끊임없는 인지의 과정이다. 그러나 인지적인 균형을 중심으로 디지털 영화의 핍진성을 연구한 문헌은 부족한 상황이다. 이에 연구자는 인지적인 균형과 디지털 영화의 핍진성이 디지털 영화에 끼치는 영향에 대해 분석하고자 한다. 이를 통해 디지털 영화에 대한 폭 넓은 연구의 가능성을 제기하고자 한다.

GAC(Global Avalanche Charateristics)은부울함수가 확산특성 관점에서 얼마나 우수한지를 전체경우에 대하여 나타내는 특성으로 Zhang-Zheng(1995) 에 의해서 제안되었다. GAC개념이 등장하기 이전에는 부분적인 확산특성에 대하여만 연구를 하였으나 다른 암호학적인 특성과 연관하여 생각하면 전체적인 확산특성이 의미가 있다. Zhang-Zheng은 GAC을 측정하는 두가지 기준을 제시하고 이 기준에 대한 하한과 상한을 구하였으며 선형함수와 벤트함수에 대하여 이러한 상한과 하한이 달성됨을 증명하였다. 그러나 암호학적으로 의미가 있는 균형인 함수의 두가지 기준에 대한 하한과 상한은 밝혀지지 않았다. 본 논문에서는 부울함수가 균형인 함수의 두가지 기준에 대한 하한과 상한은 밝혀지지 않았다. 본 논문에서는 부울함수가 균형일 때 GAC을 측정하는 기준에 대한 하한을 제시한다. 이러한 하한 아직까지 미해결 문제로 남아있는 균형인 부울 함수의 비선형치에 대한 상한을 구하는데 새로운 방향을 제시할 수 있다.

To explore the relationships among frequencies for sets of alleles, within or between loci, is one of the first analyses in population genetic study. The general question is whether the frequency of a set of alleles is the same as the product of each of the separate allele frequencies. For two alleles of a single locus, Hardy-Weinberg equilibrium is tested and for an allele from each of two loci, linkage disequilibrium is tested. However, it is more useful if we can quantify and graphically represent this information. In this study, we suggest graphical methods to find associations between alleles. We also analyze the STR data of Korean population as an illustration.

This study based on international input-output model shows various static analyses of the effects by estimating the intermediary goods' trade volume that affects the industrial production. When concluding tariff removal between Korea and Japan, as intermediary goods import increases, Korea's trade balance deficit with Japan is expected to grow more than before. However, Korea's increase in export to the world is the largest benefit Korea can earn from tariff removal between the two countries.

The discussion about capacity development (CD) has been spotlighted as significant drivers for sustainable development in recent years. Multi-dimensional natures of capacities would lead to various definitions of CD in international institutes and organizations. CD is perceived as an endogeneous process to improve actionable learning and knowledge, but most of core capacities still remain abstract notion and might be unreliable in sustainable development (SD). The paper first explicates international perspectives of CD in association with SD. An agent-based model is especially proposed to portray more details of CD. It illuminates the role of assets (or capitals, resources) in agents to impact on ingredients of CDs that are drivers or enablers for improvement of SD. A definition of sustainable capacity development is firstly articulated in international society and its conceptual framework is also creatively designed to assist concerned international organizations. The paper concludes by proposing practical spatial asset mapping linking to agent-based organizational capacity as a tool for measuring sustainable capacity development.

양축가는 금년도 두차례에 걸친 대폭적인 배합사료가격인상과 이에 따른 축산물가격이 생산비를 보장하는 수준까지 적정거래가 이루어져야 겠으며 사료메이커는 현재의 어려운 실정을 감안 양축가의 고충이 자신의 고충이라 생각하고 연관업계의 균형된 성장발전이 내 사업의 성장과 발전이란 것을 명심하여 경영합리화를 기하는 동시 조금이라도 생산원가를 낮춰 양축가에 고충을 덜어 주어 축산업의 안정적 발전을 보장하도록 노력해야 할 것이다.

In order to create an organizational culture that prevents women's career breaks and promotes economic activities, this study aimed at developing educational content for workplace culture improvement for both male and female workers working at small and medium-sized enterprises in Jeollanam-do. The core content composition and content design specifically consider the characteristics of Jeollanam-do based on an advisory meeting of the field experts and researchers to ensure the on-site utilization of the content and the validity and consistency of the teaching content. The educational content is divided into three areas: understanding, effectiveness, and the implementation of a gender-sensitive work-life balance organizational culture. The aim of the content is for all employees to understand the meaning of work-life balance and to improve the organizational culture of their company from the perspective of individuals, families, companies, and society. In particular, the intention was to personally identify and implement measures to improve a gender-equal work-life balance, not only at work, but also with regard to domestic labor and leisure time. Furthermore, the content is presented from a gender-sensitive perspective that encompasses diversity, systems, and programs targeting women, men, single people, married people, young people, the elderly, and people with disabilities - all these groups are explained as examples. The content emphasizes that we should all actively participate in improving the organizational culture of our companies. In addition, the Women's New Work Center should seek ways to increase the motivation for the voluntary participation by companies and strengthen the expertise of instructors in work-life balance education.

Balanced regional development' is rehabilitated as contemporary national agenda by Roh government. The regional equity policies has been justified as insuring more 'even development opportunity'. It is required further examination that the intrinsic relationships between spatial equity and 'the participatory democracy' of the government. The participatory democracy was estimated an important method to achieve 'the alternative development' of the new social movement. But the rapid evolution of transportation and electronic nudes of communication technology strengthened spatial concentration, especially concentration of authoritative resources. These concentrations have a tendency of participation exclusion in the symbolic social practice such as ideological and political decision-making. In order to realize participatory democracy, It is not sufficient to decentralize administration authorities. The reallocation and upbringing policies of symbolic practices such as cultural industries and education facilities is very important.
