본 논문에서는 두 개의 직전자를 갖는 90/150 비그룹 셀룰라 오토마타(TPNCA)를 생성하는 알고리즘을 제안한다. 특히, p(x)가 원시다항식일 때, xp(x)와 x(x+1)p(x)를 최소다항식으로 갖는 90/150 TPNCA를 주어진 알고리즘을 이용하여 각각 합성한다. 이 CA는 90/150 TPNCA에 기반한 의사난수열 생성 연구에 유용하다. 또한 해슁을 연구하는데 유용한 TPSACA와 TPMACA를 합성한다.

The digital logic systems(DLS) is classified into digital combinational logic systems(CDLS) and digital sequential logic systems(SDLS). This paper presents a method of constructing the digital sequential logic systems without feedback. Firstly we assign all elements in Finite Fields to P-valued digit codes using mathematical properties of Finine Fields. Also, we discuss the operarional properties of the building block T-gate that is used to realizing digital sequential logic systems over Finite Fields. Then we realize the digital sequential logic systems without feedback. This digital sequential logic systems without feedback is constructed ny following steps. Firstly, we assign the states in the state-transition diagram to state P-valued digit dodo, then we obtain the state function and predecessor table that is explaining the relationship between present state and previous states. Next, we obtained the next-state function and predecessor table. Finally, we realize the circuit using T-gate and decoder.

The purpose of this study is to understand the familial and economic problems(household-financial management) came out as a result of inheritance in household with a qualitative Ethnographic interview analysis method. As a result of interview, we found out three results; first, inheritance consciousness, attitude of predecessor(parents generation) second, the changes in familial economic relationship by inheritance stages (pre-inheritance stage, inheritance progressing stage, post-inheritance stage) third, the emotional changes of predecessor(paraents generation). The results indicated that there were significant importance and influence of household inheritance, therefore, the necessities of definite and systemic old-aged plan with financial management of inheritance should be introduced.

This pper presents a method for constructing multiple-valued logic sequential machines based on Galois field. First, we assign all elements in GF(2**m) to bit codes using mathematical properties of GF(2**m). Then, we realized the sequencial machine circuits with and withoutm feed-back. 1) Sequential machines with feed-back are constructed by using only MUX from state-transition diagram expressing the information of sequential machines. 2) Sequential machines without feed-back are constructed by following steps. First, we assigned states in state-transition disgram to state bit codes, then obtained state function and predecessor table explaining the relationship between present states and previous states. Next, we obtained next-state function from state function and predecessor table. Finally we realized the circuit using MUX and decoder.

The present study analyzes the relationship between research and development (R&D) inputs and performance of a national technology innovation R&D program using successive binary Logistic regression models based on a typical R&D logic model. In particular, this study focuses on to answer the following three main questions; (1) "To what extent, do the R&D inputs have an effect on the performance creation?"; (2) "Is an obvious relationship verified between the immediate predecessor and its successor performance?"; and (3) "Is there a difference in the performance creation between R&D government subsidy recipient types and between R&D collaboration types?" Methodologically, binary Logistic regression models are established successively considering the "Success-Failure" binary data characteristic regarding the performance creation. An empirical analysis is presented analyzing the sample n = 2,178 R&D projects completed. This study's major findings are as follows. First, the R&D inputs have a statistically significant relationship only with the short-term, technical output, "Patent Registration." Second, strong dependencies are identified between the immediate predecessor and its successor performance. Third, the success probability of the performance creation is statistically significantly different between the R&D types aforementioned. Specifically, compared with "Large Company", "Small and Medium-Sized Enterprise (SMS)" shows a greater success probability of "Sales" and "New Employment." Meanwhile, "R&D Collaboration" achieves a larger success probability of "Patent Registration" and "Sales."

The International Chamber of Commerce introduced in September 1999 its new publication Incoterms 2000(ICC Publication No 560). The ICC was building on the past experiences in its revision works. I have discussed and commented constructively some main features and problems of the new set of terms. Incoterms 2000 takes into account, like already its predecessor did, the possibility that the parties may decide to communicate electronically and replace a paper transport document by an equivalent electronic data interchange message. This possibility will certainly be much more used under the present set of terms. Incoterms 2000 is well recognised by the international legal community, taking into account also the endorsements by UNCITRAL to its predecessor in the early 90's. Incoterms 2000 does not have major competitors remaining. However, the ICC still faces a battle to convince more traders to refer to its terms and to teach traders to understand and to apply them correctly. Incoterms 2000 is a tool for international trade created by a global business organisation. Its members decide every day if and to what extent they make use of this tool. The members of the ICC have participated actively in the drafting and commenting of Incoterms 2000 and thereby shown again a great deal of dynamism in creating rules for their own everyday use. Under these circumstances, "ship's rail approach" related to delivery point, risks and costs should be replaced by "on board approach" under FOB, CFR and CIF terms.

시간이 흐름에 따라 위치가 연속적으로 변경되는 객체를 이동 객체(Moving Objects)라고 한다. 이러한 이동 객체의 대용량 궤적 정보를 효율적으로 검색하기 위해서 색인이 필요하며 대표적인 색인으로 TB-tree가 있다. 그러나 전통적인 공간 색인인 R-tree 기반의 TB-tree는 엄격한 궤적 보존 정책에 의해 레코드가 삽입될 때마다 해당 레코드의 선행자(predecessor)를 포함하는 단말 노드를 검색해야 하며, 레코드 삽입으로 인한 단말 노드 MBB의 변경을 해당 단말 노드에서부터 루트 노드까지 반영해야하는 갱신 부하를 가지고 있다. 본 논문에서는 대용량 궤적 정보의 효율적인 색인을 위한 TB-tree 갱신 기법을 제안한다. 본 기법은 앞으로 삽입될 이동 객체의 궤적을 포함하는 예상된 MBB(EMBB: Expected Minimum Bounding Box)를 트리에 먼저 반영한다. 그 후 새로운 레코드가 삽입될 때마다 중간 노드의 MBB를 갱신하지 않고, 삽입되는 레코드의 MBB가 EMBB을 벗어났을 때 EMBB를 재설정하여 실제로 삽입된 레코드의 MBB와 재설정된 EMBB를 포함하도록 중간 노드의 MBB를 조정하므로 TB-tree의 MBB 조정 횟수를 줄인다. 또한 TB-tree에 선행자를 포함하는 단말 노드를 직접적(direct)으로 접근하기 위하여 별도의 선행자 테이블(Predecessor Table) 구조를 두어 레코드 삽입을 위해 선행자를 포함하는 단말 노드의 검색비용을 줄여 전체적인 색인 갱신 비용이 감소된다.

This study is about saliva from a GIGONG's point of view, it's importance, and it's funtion that recently medical world proved. And here is GIGONG training with saliva. The results were summarized as follows. 1. It is detected that saliva have function to prevent symptoms of senility and have effect of an $anti{\sim}cancer$ medically in recent years. So it is said that science proved narrowly that so called a predecessor speak of salive interms of high praise and they already experienced. 2. Similar substance to saliva exist in human body besides nature food, but human body have materials that deal with all situation to occur from every kind of environment and disease. And exactly saliva is an example of it. 3. We cannot turn back sweat, blood, tears and sperm again that is out of human body once, but we can swallow again only saliva. Therefore, we must experience training that swallow saliva to make us healthy by ourselves, and we don't have to commit a foolish act to cough up saliva at random that a predecessor speak of in terms of high praise, and to be second to JUNG(精). 4. Saliva is a kind of antibody or hormone, so I think that we need to make a study of using saliva with a GUIGONG that is an example of way to strengthen immunity of human body.
