A better selection model on management innovative enterprises is needed since the Korean government provides multi benefits to those selected enterprises. However, the selection model's propriety is suspicious because of the shortage of consideration of assessment items. In particular, the most important two assessment items, strategy and performance are suspected of multicollinearity because of high correlation scores. No consideration on multicollinearity among those items leads to erroneous selection which doubly counts the same components with different item names. The principle component analysis is applied to factor out the uncorrelated items. Using the resulted principle components, the new estimations are carried out. The comparison between estimated results from using principle components and non principle components shows that the present selection model overly considers the performance items compared to the real effect of items, which is a result of multicollinearity between performance and strategy.

In this paper, we studied Dongssi' acupuncture therapy via the consideration of development process of Oriental medicine in history. We investigated the distribution chart and naming of Dongssi' acupuncture point in human body, artificial selection principle of Dongssi' acupuncture point to therapy (選穴原則) on the various diseases, the therapy of pyo-bon (標本理論) and the therapy of Geun-Gyeal (根結理論) and compared GeoZa-principle (巨刺法) and MuZa-principle (繆刺法) with artificial selection principle of Dongssi' acupuncture point. And we also studied the acupuncture therapy of DongGi (動氣鍼法), DoMa (倒馬鍼法) and SaeIn (索引鍼法), which is the unique principle in Dongssi' acupuncture theraphy, to consider with the other Oriental medicine theory which is the theory of ZangSang (臟象學說) and BiWi (脾胃學說) etc. Our desire in this study is the giving aid to treatment diseases with the acupuncture therapy in Oriental medicine.

이 글은 직설법 조건문에 대한 스톨네이커의 의미론을 제시하고 옹호한다. 직설법적 조건문에 대한 스톨네이커의 가능세계의 의미론은 표준적인 가능세계와 조건문에 대한 선택함수 의미론, 그리고 직설법적 조건문에만 적용되도록 선택함수를 제한하는 화용론적 원리로 구성된다. 그의 의미론에 따르면, 직설법적 조건문은 강한 진리조건을 갖기 때문에 논란없는 원리는 받아들이지만, 이행원리가 보편적으로 성립한다는 것은 거부한다. 그럼에도 이행원리가 성립하는 경우가 있을 수 있는데 그것이 어떻게 가능한지를 설명함으로써 직설법적 조건문에 대해서 우리가 갖는 일반적인 직관을 잘 설명하는 이론임을 보인다. 또한 이 글은 스톨네이커의 이론에 대하여 제기되는 아담스주의적 비판과 기바드 현상의 문제에 대해서 답하고, 스톨네이커의 의미론은 지나치게 맥락의존적이라는 비판에 답함으로써 직설법적 조건문에 대한 가장 받아들일 만한 이론임을 주장한다.

PyoBon GeunGyul - one of the twelve regular meridians theory - play a important role on the principle of point selection and point prescription in acumoxibustion. PyoBon explain the connection of the concentration and diffusion of channel qi, GeunGyul explain the relation of both poles of channels flow. So, Geun and Bon means the starting point of channel qi, and Pyo and Gyul means the terminal point of channel qi. But the flow of channel qi on PyoBon GeunGyul different from today's circulation courses of twelve regular channels based on Kyungmaek(經脈) chapter of Youngchu. Thus this study investigate the contents of PyoBon GeunGyul and consider its connection with channel flow. The results are as follows : 1. PyoBon GeunGyul theory explain that the relation of the limbs and trunk at meridian and emphasize that the connection of meridian and the importance of the limb acupoints. 2. PyoBon GeunGyul theory can be understandable in the view of the primordial qi and explain that the primordial qi of twelve regular channels acts from the limbs to the trunk. 3. PyoBon GeunGyul theory is based on the system of primordial qi channel which circulates from fingers and toes facing toward heart or the head, different from today's circulation courses of twelve regular meridians. 4. PyoBon GeunGyul theory act as a basis of principle of a part or distant point selection which applicated widely in acumoxibustion.

표본조사에서 이용하는 모수 추론 방법인 설계기반추론과 모형기반추론을 고찰하였다. 설계기반추론은 확률화 원리에 기초를 두고 있는 반면 모형기반추론은 가정한 모형에서 조건부 원리와 우도 원리에 바탕을 두고 있다. 두 추론은 서로 다른 이론적 근거를 사용하기 때문에 이론적 기초에 관한 논쟁이 오래 전부터 있어 왔으며 지금도 진행되고 있다. 이 논문에서는 두 추론 사이에 진행되었던 논쟁의 초점을 살펴보았고 몇 가지 관점에서 두 추론의 장단점을 비교하였다.

Variable selection is one of the most crucial tasks in supervised learning, such as regression and classification. The best subset selection is straightforward and optimal but not practically applicable unless the number of predictors is small. In this article, we propose directly solving the best subset selection via the genetic algorithm (GA), a popular stochastic optimization algorithm based on the principle of Darwinian evolution. To further improve the variable selection performance, we propose to run multiple GA to solve the best subset selection and then synthesize the results, which we call ensemble GA (EGA). The EGA significantly improves variable selection performance. In addition, the proposed method is essentially the best subset selection and hence applicable to a variety of models with different selection criteria. We compare the proposed EGA to existing variable selection methods under various models, including linear regression, Poisson regression, and Cox regression for survival data. Both simulation and real data analysis demonstrate the promising performance of the proposed method.

In sample surveys, we expect preferred samples that reduce the survey cost and increase the precision of estimators will be selected. Goodman and Kish (1950) introduced controlled selection as a method of sample selection that increases the probability of drawing preferred samples, while decreases the probability of drawing nonpreferred samples. In this paper, we obtain the controlled plans using the maximum entropy principle, and when the order of nonpreferred samples is considered, we propose the algorithm to obtain a controlled plan.

G. Gruenhage gave a characterization of paracompactness of locally compact spaces in terms of game theory ([6]). Starting from that result we give another such characterization using a selective version of that game, and study a selection principle in the class of locally compact spaces and its relationships with game theory and a Ramseyan partition relation. We also consider a selective version of paracompactness.

This presentation is a short summary of the Finnish process for selection and characterisation of potential sites for geological deep disposal of spent nuclear fuel. The process lasted nearly two decades from 1983 to 2000, and was concluded by the Government's Decision in Principle (DiP) on the construction of a repository in Olkiluoto. This presentation gives an outline of the early site selection criteria and a description of this process.

This paper deals with manufacturing process design of a simplified gun tube applying CE principle. A concept and characteristics of CE, mathematical model for understanding interaction between design and manufacturing, basic elements and related equations for process planning and cost estimating are introduced. A Knowledge-based Computer-Aided Process Planning System(KCAPPS) is constructed, yielding optimal production cost/time for the shape input and selection of appropriate machines and tools.
