Effects of stress-induced suppression of humoral immunity on scuticociliate killing activity of olive flounder plasma were investigated. Changes in glucose level. alternative complement activity and Iysozyme activity of plasma by handling stress were analysed in relation to in vitri parasiticidal activity of plasma. The plasma glucose level was about two times higher in fish after a handling stress than in control fish. Plasma lysozyme activity and natural haemolytic activity were decreased in suessed fish.The scuticociliate killing activity of plasma was significantly lower in stressed fish than in non-stressed control fish. The present results indicated that stress-induced immunodepression could be a cause of scuticociliatosis occurrence in olive flounder.

The quantum logic was introduced by G. Birkhoff and 1. von Neumann in order to study projections of a Hilbert space for a formulation of quantum mechanics, and Husimi proposed orthomodular law and orthomodular lattices to complement the quantum logic. Abott introduced orthoimplication algebras and its properties to investigate an implication of orthomodular lattice. The commuting relation is an important property on orthomodular lattice which is related with the distributive law and the modular law, etc. In this paper, we define a binary operation on orthoimplication algebra and the greatest lower bound by using this operation and research some properties of this operation. Also we define a homomorphism and characterize the commuting relation of orthoimplication algebra by the homomorphism.

When new services are introduced, one of the drivers for market performance of them is the interactions among existing and new services. They are characterized by the substitution or complementary effects among existing and new service or the cannibalization of existing services by new services. This paper analyzes these issues in the telecommunications service industry context. To analyze them, a simple graphical tool or State Transition Diagram(STD) is developed and used. The diagram helps to clearly represent and explain the substitution, complement and cannibalization impact. Then, using the face-to-face survey of 1,200 people, a new wireless internet access service or WiBro is analyzed to identify the substitution/complement and cannibalization impacts in relation with the other competing services. Additionally, the important factors explaining customer subscription and substitution behavior are identified. The analysis results indicate that males, students or on-line game users are more likely to subscribe WiBro. Also, among the potential WiBro subscribers, customers who are less satisfied with the existing fixed line broadband internet access services are more likely to stop subscribing the fixed line service, which implies substitution by a new service. Additionally, this raises the issue of cannibalization if the existing and new services are provided by the same company. In fact we find the cannibalization effect is more serious for the cost sensitive group. We believe that our tool, approach, analysis results and their implications would be very helpful to devise a winning strategy for the new services in the highly uncertain telecommunications business environment.

In a machine translation system, word sense disambiguation has an essential role in the proper translation of words when the target word can be translated differently depending on the context. Previous research on sense identification has mostly focused on adjacent words as context information. Therefore, in the case of nominal compounds, sense tagging of unit nouns mainly depended on other nouns surrounding the target word. In this paper, we present a practical method for the sense tagging of Korean unit nouns in a nominal compound. To overcome the weakness of traditional methods regarding the data sparseness problem, the proposed method adopts complement-predicate relation knowledge that was constructed for machine translation systems. Our method is based on a sentential form recovery technique, which recognizes grammatical relationships between unit nouns. This technique makes use of the characteristics of Korean predicative nouns. To show that our method is effective on text in general domains, the experiments were performed on a test set randomly extracted from article titles in various newspaper sections.

To complement and develop the Orient Medical Bian Zheng treatmemt(韓方辨證施治), I have observed and analysed 68 persons who have recieved medical treatment because of the epigastric pain. Considering and analysed the Clinical Diagnosis(臨床診斷) and Clinical Bian Zheng(臨床辨證), Clinical Diagnosis(臨床診斷) and Gastroscopic Bian Zheng(微觀辨證), Clinical Bian Zheng(臨床辨證) and Gastroscopic Bian Zheng(微觀辨證), case history, age and sex, I have obtained the conclusion as follows. 1. The frequency of epigastric pain according to the classfication of Clinical Bian Zheng(臨床辨證) most occured in Gi Che Zheng(氣滯證), then in Huh Han Zheng(虛寒證). and least in Wi Youl Zheng. 2. There is no clear connection between the Clinical Bian Zheng(臨床辨證) and Clinical Diagnosis(臨床診斷). 3. The frequency of the epigastric pain according to Gastroscopic Bian Zheng(微觀辨證), mainly occurred in Wi youl Type(胃熱型), Wi Rac Jac Sang Type(胃絡灼傷滯型)and then occurred in Wi Han Type(胃寒型), and least occurred in Wi Rac A Che Type(胃絡瘀滯型) 4. Having observed the relation between the Gastroscopicin Bian Zheng(微觀辨證), and Clinical Diagnosis(臨床診斷) as pathological process, I have obtained the result that Wi Youl type(胃熱型) and Wi Rac Jac Sang Type(胃絡灼傷型) mainly occurred in Erosive Gastritis and Superficial Gastritis at the early stage, and Wi Rac A Che Type(胃絡瘀滯型) occurred in the whole stage among the Wuperficial Gastritis, Atro pic Gastritis, and Erosive Gastritis, Gastric Cancer, and the Wi Han Type(胃寒型) mainly occurred in Atropic Gastritis at the later stage. 5. The relation between Clinical Bian Zheng(臨床辨證) and Gastroscopic Bian Zheng(微觀辨證) do not coincide. 6. Observing the relation between the Clinical Bian Zheng(臨床辨證) and case history, Gi Che Zheng(氣滯證), Huh Han Zheng(虛寒證), Wi Youl Zheng(胃熱證) were commonly seen in the early stage of the case history, and Eum Huh Zheng(陰虛證) and Houl A Zheng(血瘀證) were seen in every stage. 7. Observing the relation between the Clinical Bian Zheng(臨床辨證) and age, Gi Che Type(氣滯型) was mostly seen in the thirties and other Bian Zheng(辨證) was seen after the middle 8. Observing the relation between the Clinical Bian Zheng(臨床辨證) and sex, Gi Che Type(氣滯型) was seen at high ratio in both sexes. 9. Observing the relation between the Gastroscopic Bian Zheng(微觀辨證) and case history Wi Han Type(胃寒證), Wi Youl Type(胃熱型), Wi Rac Jac Sang Type(胃絡灼傷型) were seen in the early stage of the case history Wi Rac A Che Type(胃絡瘀滯型) was mostly seen in the later stage. 10. There was no clear connection between the Gastroscopic Bian Zheng(微觀辨證) and age, sex. Although the examples were not sufficient, recipe regarding the partial variation state of stomach mucos together with Orient Medical Bian Zheng(韓方辨證) treatment seems to be useful in the effective treatment of Bi wi(脾胃) disease besides the epigastric pain.

Among the various methods of realizing low sensitivity digital filters. LBR two-pair cascading is one which enables us to realize low sensitivity filter without referring to any analog prototype filters. In this paper we analyze the LBR cascade structures through the fundamental approach to them based on the WDF theory, and interpret their features described solely in the digital domain in relation to the corresponding analog circuit Besides, we derive in a unified manner various LBR constraints needed for the LBR cascade realization, point out the insufficiency lurking in the existing description of the Type 3 LBR constraints, complement it, and make the LBR two-pair cascading procedure complete.

Recently, the youth employment crisis which is characterized by high unemployment and low employment rate has been considerably serious, while jobless growth has been observed. However, job shortage and unstable labor status of the old are also main issues. To solve this problem, the job creation and deferred retirement for the old has been proceeded. Consequently, it has caused to the intergenerational war on job due to equity of job creation for the youth. However, it is not desirable that the problem would be diagnosed and the policy would be set up although little attention has so far been paid to test empirically this kind of substitution relation. Thus, this research has been analyzed whether the employment relation between the youth and the old is substitution or not. The analysis method is panel data analysis in 15 OECD countries including Korea(1990~2000). Major findings are as follows. First, only half of the youth and the old works. It provides the evidence that the employment crisis is not a problem of special generation but all of them. Second, employment relation between generations followed by panel analysis is not substitution relation. This findings can be interpreted as evidence that it is unlikely to solve the youth employment matter even though the government encourages the early retirement.

The relation between dietary behavior and fast food consumption was investigated among 117 male and 164 female students at a high school in Seoul. The main reason for eating fast foods was convenience. In addition, they used fast food chain stores as a get together place with friends. They enjoyed taste of fast foods as well as the atmosphere of stores but they regarded fast foods somewhat expensive for high school students. Among them, 30.1% of the female students had irregular meals and they ate more irregularly than males. More students took too much or too little amount(45.3% of male, 52.5% of female students) than those who took adequate amount. They skipped breakfast the most frequently because they are in a hurry. Most students took snacks once a day and they considered taste of snacks was more important than nutrition or price. They consumed less calorie, calcium, iron, and riboflavin than RDA. Mean caloric intakes of males and females were 79.0% and 97.1% of RDA, respectively. Mean calcium and iron intakes were less than 70% of RDA. Among many factors that may influence nutrient intake, anthropometric indices turned out to be the most influential. Body weight showed significantly positive correlation with caloric, protein, thiamin, and ascorbic acid intakes in male students where both height and weight showed positive relation with calorie, protein, and iron intakes in females. Therefore, this study suggested that fast food stores should make efforts to provide more foods and beverages which are supplemented with calcium and iron. Also, better nutrition education programs should be established to improve high school students dietary habit to complement these nutrients.

The MFC makes the region in the player object center and it judges a relation the object. But it searches the objects which are not relation to game. Consequently, it decreases the speed of game and it recognizes a dangerous characteristic. In this paper, in order to complement a weak point, it applied the avoidance rule of the flocking in npc object. Consequently, the npc object has the concept of range of vision and proposed the method which is possibility of closing the speed decrease of game. This time 2 condition which is proposed must be satisfactory. The method that proposed will play an important role in development of a 3D FPS games.

In the component-based software development environment, it is important for developers who compose components to provide the information of dependence relationship between components. However it is not provided the information of dependence relationship of components. Therefore, it happens that the developer occasionally composes the components without knowing the dependence relation between the primitive components. In order to complement these disadvantages, In this paper, the design and implementation of dependence manager which provides the component dependence information for the development of integrity and persistence information system are established by defining the information about the dependence and relation between components as XML, managing them and providing a developer with the information about the dependence relationship between primitive components, we can establish. The components being created in the dependence manager show that the figure of reused matrix measurement is indicated from $89\%\;to\;95\%$, being included in confidence limits.
