In this study, problems with table serving of Korean Jeollanamdo food were investigated, and methods for improvement were suggested. The manner of food serving and arrangement on tables, as well as the serving space in each case, were investigated in representative restaurants serving Jeollanamdo food. The results showed that most of the Jeollanamdo Korean food have a prototype of a flat serving sprea, wherein the main dish and side dishes are not clearly identified, the demarcation between shared space and personal space is insufficiently made for each serving on the table, and the table is full of side dishes, that are narrow, visually disordered and unhygienic, both in terms of the table setting and arrangement inside bowls. To provide sufficient eating space, elevate awareness of hygienic and clean serving, and identifying the main dish in the table setting, a serving method that is a compromise between the flat spread-out and time-series development was suggested, and an arrangement on the table was defined for the main dish and side dishes. The utilization of table space was also increased by reducing the number of dishes on the table at a given moment. In addition, the dish or bowl and arrangement inside the container were changed in order to distinguish the main dish and side dishes. It is suggested that some of tableware be linked with the special products of the locality so as to make a brand for them, and that a personal mat be used to arrange the tableware for each one, since there are many fermented food items (salted fish, kimchi, fermented paste and sauce, etc.) and boiled food items (stew, steamed dish, boiled dish in sauce, etc) that look dark and unfocused. In addition, it is suggested that the width and breadth of the dishes or bowls be set in an orderly manner. Considering the tables currently available at restaurants, personal space on a table and comfortable distance between eaters are suggested to be $400 mm{\times}250 mm$ and 300 mm, respectively.

The environment of automobile industry in the world is rapidly changing. It is changing of high oil price, technology, environment and construction of competition by newly rising an economic district. Automobile company is focusing on three issue because they want to reinforce competition of automobile industry in the world. That is innovation of production profit management through quality management and Lean. Chance of success is separated in R&D, providing distribution, manufacture, distribution, selling in automobile industry. Emphasis on development process, distribution process, manufacture process, circulation and selling process for strengthening the competitiveness and guarantee. In this thesis, we try to analysis the data set period of automobile production by using survival analysis. While using mean comparison of general statistics commit mistakes, survival analysis can used for including censored data in order to heighten analysis efficiency.

Aphids can damage plants directly by absorbing their phloem sap and indirectly by transferring plant viruses and causing sooty mold. We compared the thermal effect on the development, survivorship, and reproduction of four cereal crop-damaging aphid species, Rhopalosiphum padi, Aulacorthum solani, Aphis craccivora, and Acyrthosiphon pisum using a life table analysis method. We investigated the stage-specific development period, survivorship, adult longevity, and fecundity of the above mentioned four aphids at 10, 15, 20, 25, and 30℃, respectively, and analyzed their life table parameters using the age-stage, two-sex life table analysis. A. solani nymphs could not complete their development to adulthood at 30℃. The intrinsic increase rate of R. padi was the highest at all tested temperatures except for that at 15℃ (0.12, 0.34, 0.47, and 0.32 at 10, 20, 25, and 30℃, respectively), and that of A. pisum displayed negative values at 30℃ (-0.04). It is speculated that R. padi would be a dominant species under high temperature conditions and A. solani is a highly adaptive species at low temperatures through the comparative analysis of the life table parameters of four aphid species damaging to cereal crops.

This study was conducted in order to compare the sequential changes of marital partnership and average marital life expectancy in Korea using Korean marriage life table for 1970, 1980, and 1985. The marriage life table was constructed by the Wolfbein-Wool method of constructing a working life table. Data used in this study was obtained from the Population Census Reports of Korea and the Korean Abridged life Tables. Some of the finding may be summarized as follows : 1. The marital partnership findings showed that males in the 40-44 age group in 1970 and in 1980 and those in the 45-49 bracket in 1985 have the highest rates of any other age interval, the percentages were 97.5% 97.3% and 96.9% respectively. The highest marital partnership rates for females were those aged 30-34 in 1970 and in 1980 and 35-39 in 1985:these were 94.6% 94.3% and 93.30% respectively. 2. The marital rate of the youngest age group has decreased due to the increasing amount of people marrying at older ages. On the other hand, the marital rates of the elderly has increased slightly due to the decreasing mortality rate. 3. The enterance rate of marriage at the 15-19 female age group ad the 20-24 male age group has decreased. 4. The secession rate of marriage has gradually decreased due to the decrease in the mortality rate. The main reason of secession for males is his own death. For females, the main reasons are divorce and the death of her spouse. 5. Korean average marital life expectancy has improved in general. In 1985 the average marital life expectancy for males was higher by 4-5 years than for females. The average difference of marital expectancy and life expectancy is about 1.4 - 1.5 years for males and about 11-14 years at the age groups below 60 years for females.

Transporting a large table using multiple robotic agents requires at least two group behaviors of homing and herding which are to bo coordinated in a proper sequence. Existing GP methods for multi-agent learning are not practical enough to find an optimal solution in this domain. To evolve this kind of complex cooperative behavior we use a novel method called fitness switching. This method maintains a pool of basis fitness functions each of which corresponds to a primitive group behavior. The basis functions are then progressively combined into more complex fitness functions to co-evolve more complex behavior. The performance of the presented method is compared with that of two conventional methods. Experimental results show that coevolutionary fitness switching provides an effective mechanism for evolving complex emergent behavior which may not be solved by simple genetic programming.

Data which gathered and used in the field of fatigue and fracture mechanics have a lot of uncertainties. In this case, those uncertainties will make scatter band in evaluation of fatigue life and fracture toughness. Thus, the probabilistic analysis of these data will be needed. For determining the fatigue life in mixed mode, using crack direction law and fatigue crack growth law, the problem is studied as a constrained life minimization. Stress intensity factor(SIF) is computed by approximate solution table(Ewalds/Wanhill 1984) and 0th order PFEM. The variance of fatigue life and SIF are computed by differentiation of tabulated approximate solution and 1st order PFEM. And these are used for criterion of design values, principal parameter determination and modelling. The problem of center cracked plate is solved for checking the PFEM model which is influenced by various parameters like as initial crack length, final crack length, two fatigue parameters in Paris Equation and applied stress.

Ground reinforcements is the essential method to prevent the liquefaction of loose sand deposit, However, in the construction of the life lines, it is impossible to treat the whole loose deposit against liquefaction. As an countmeasure for the life lines against the liquefaction, a monitorning system can be considered for an immediate judgement of the liquefaction occurrence during an earthquake. Through shaking table tests on model grounds, pore presure developments were investigated in terms of the surface spectral velocity, which was verified as a tool for the immediate judgement of the liquefaction occurrence.
