토양 속에서 발생될 수 있는 용질과 용매의 복합 수송시스템을 대상으로 한 연구 중 회석상태로부터 포화상태에 이르기까지의 넓은 농도분포를 가지는 토양 용액에 적용될 수 있는 물리 화학적 이론에 입각한 지배방정식을 발표한 연구는 전무한 실정이다. 본 연구는 용매와 토양기체간 그리고 용질과 결정간의 상변화를 고려한 연립물질수지방정식을 제시하고, 여기에 타율적 대류를 포함하는 상호확산 분산수송방정식을 도입하여 대류와 확산에 관한 프럭스를 분리, 결정하는 것을 목적으로 한다. 대류 플럭스의 결정은 타율적으로 이루어지는 것이 이론적으로 타당하며, 이러한 타율적 대류 플럭스가 제공된다면 본 연구에서 제시된 지배방정식을 이용해서 토양용액의 복합수송 시스템을 범용적으로 해석, 예측할 수 있을 것으로 판단된다.

In this paper we reanalyze Kohonen‘s learning vector quantizing (LVQ) Learning rule which is based on Hcbb’s learning rule with a view to a gradient descent method. Kohonen's LVQ can be classified into two algorithms according to 6learning mode: unsupervised LVQ(ULVQ) and supervised LVQ(SLVQ). These two algorithms can be represented as gradient descent methods, if target values of output neurons are generated properly. As a result, we see that the LVQ learning method is a special case of a gradient descent method and also that LVQ is represented by a generalized percetron-like LVQ(PLVQ).

Since Aristotle, human capability has been understood as the form of existence. The capability is presupposed before execution in mainstream economics, Marx's capitalist labour process, even socialist labour process. Of course, Marx shows that the value of capability and execution is different in capitalist labour process. Also Marx points out heteronomy that producer can't have products as his own. Even socialist labour process can't cut off shackles of heteronomy. It is necessary to change way of thinking in order to cut off shakles of heteronomy and to develop human's full potential. The changing way of thinking is to restore labour into primary labour which is purpose as life itself not means. Human capability is potential. We can't define potential as the form of existence. Human capability is promoted by free will. True freedom promoting human capability is realized by rebuilding in individual property depending on distribution principle by the needs in the association of free individuals.

The 10th constitution established in 1987 serves as the theoretical foundation of democracy in South Korea in the 21st century. Respect for human rights, resistance to injustice, and equality consciousness inherent in this constitution do not conflict with the content of Confucian philosophy. This means that the spirit of the constitution of South Korea in the 21st century was formed under the influence of the idea of democracy and Confucian philosophy. However, the 10th constitution attaches importance to the idea of the 'Basic free and democratic order', which was accepted in the Yushin constitution and inherited by the military forces. The Yushin constitution was affected by liberalism that prioritizes freedom over equality rather than supporting the compatibility between freedom and equality. Therefore, policies to expand the interests of the bourgeoisie rather than public welfare or the interests of the public have been implemented frequently. In particular, during the Lee Myeong-bak and Park Geun-hye regimes, many unequal phenomena were mass-produced. Confucian philosophy in the 21st century critically sees this unequal society. Confucian philosophy thinks that a sense of relative deprivation plays a role of alienating humans and emphasizes the importance of equal relationships. In addition, this constitution emphasizes the rule of law. However, the rule of law attaches importance to positive laws when the spirit of the constitution that contains natural law is applied to reality through systems. This rejects autonomous judgments and choices while inducing reliance on heteronomy. These heteronomous laws as such are accompanied by forcibleness. The positive laws as such can degrade humans into passive beings that indiscriminately adapt themselves to frames already set instead of active beings that think freely and creatively. Confucian philosophy regards and criticizes the rule of law as a system that makes humans into a means. Confucian philosophy regards humans as moral beings instead of tools. Confucian philosophy seeks to build a healthy society through morality accomplished through conscious realization of the principles of life. Confucian philosophy regards humans as originally free beings. Therefore, human beings are autonomous beings, not heteronomous beings. According to Confucian philosophy, humans beings that can realize the morality contained in their inner side by themselves to responsibly carry out their own judgments and choices. Therefore, Confucian philosophy, which considers human beings as beings to be trusted instead of beings to be distrusted, attaches importance to the realization of human decency through edification rather than by punishment through the law. This means that human values cannot be kept by the heteronomy termed positive laws but the identity of humans can be maintained by voluntary choices and judgments. As such, the comment of Confucian philosophy on the problems of liberal democracy and positive laws contained in the 10th constitution can be helpful in essentially solving the contradictions of modern South Korean society.

과거 산업사회는 수직적인 조직구조에 타율적, 비 자발적인 인사결정이 이루어졌으며, 하드워커(Hard Worker)가 성공하는 사회였다. 그러나 현재의 정보화사회는 하드워커보다는 하드싱커(Hard Thinker)의 인재형을 필요로 한다. 또한 인간의 노동력 대신에 하이테크를 활용, 부가가치를 높이는 특징도 가지고 있다. 이러한 상황하에서 나타나 것이 스마트경영이다.

In baseball game, the hitting ability of batter is frequently assessed by a batting average, a run batted in, a home run, a run scored, an on-base percentage, etc. Recently, more comprehensive indicators such as OPS, ISO, SECA, TA, RC and XR are often used. But, these measures generally shows large deviations since they are calculated from the data for a certain period of time, and they are not an estimate of a population parameter, either. In this paper, we will presume the pure hitting ability of the korea professional baseball players as a parameter which is depend upon at bat. We will estimate the parameter by using the Bayesian method.
