In this division, regarding the establishment of operation system of Conservation Science Center, we have tried to find out research trends and advanced operation system of Italian conservation centers, which play an active part in the field of restoration of cultural properties internationally. And the results will be utilized for the establishment of Conservation Science Center. Italy is a country having a long history of restoring cultural properties. In this field, it is largely divided into research & development institutes. And restoration institute and they are operated under system in which research & development institute implement research projects for restoring cultural properties and restoration specialists take receive the results and utilize them. They have different business processing system compared to Conservation Science Center which will implement research-development and restoration(conservation treatment) concurrently. Each institute, carrying out differentiated and specialized research projects per region, maintains smooth cooperative relationship with national institutes, neighboring universities and even afflated schools through horizontal-mutual collaboration joint research, and sharing of equipments, in the field of cooperation between national institutes, cooperation with neighboring universities, and connection to belonging schools. There institutes show us a good example which can be utilized in the future organizational structure of Conservation Science Center. It is expected that their operation system and possessed technologies such as utilization of human resources pool and cooperation with relevant fields can be used usefully in the management and operation of Conservation Science Center.

Wind-excited vibrations of slender structures can induce fatigue damage and cause structural failure without exceeding ultimate limit state. Unfortunately, the growing importance of this problem is coupled with an evident lack of simple calculation criteria. This paper proposes a mathematical method for evaluating the crosswind fatigue of slender vertical structures, which represents the dual formulation of a parallel method that the authors recently developed with regard to alongwind vibrations. It takes into account the probability distribution of the mean wind velocity at the structural site. The aerodynamic crosswind actions on the stationary structure are caused by the vortex shedding and by the lateral turbulence, both schematised by spectral models. The structural response in the small displacement regime is expressed in closed form by considering only the contribution of the first vibration mode. The stress cycle counting is based on a probabilistic method for narrow-band processes and leads to analytical formulae of the stress cycles histogram, of the accumulated damage and of the fatigue life. The extension of this procedure to take into account aeroelastic vibrations due to lock-in is carried out by means of ESDU method. The examples point out the great importance of vortex shedding and especially of lock-in concerning fatigue.

Fiber reinforced plastic (FRP) rods are used as reinforcement (prestressed or not) to concrete. FRP composites can also be combined with steel to form hybrid reinforcing rods that take advantage of the properties of both materials. In order to effectively utilize these rods, their bond behavior with concrete must be understood. The objective of this study is to characterize and model the bond behavior of hybrid FRP rods made with epoxy-impregnated aramid or poly-vinyl alcohol FRP skins directly braided onto a steel core. The model closely examines the split failure of the concrete by quantifying the relationship between slip of the rods resulting transverse stress field in concrete. The model is used to derive coefficients of friction for these rods and, from these, their development length requirements. More testing is needed to confirm this model, but in the interim, it may serve as a design aide, allowing intelligent decisions regarding concrete cover and development length. As such, this model has helped to explain and predict some experimental data from concentric pull-out tests of hybrid FRP rods.

With both Gatdui and Daean areas, under construction for upgrading the old housing in Gyeongju downtown area, this study was carried out to find out implications of upgrading methods in a historical and cultural city, by using a physical survey in the areas and life survey among their residents, as well as by analysing the level of their satisfaction with and requirement for housing and their preferring housing type. The upgrading patterns of residents were analysed by examining cases constructed newly in the manner of upgrading. The findings showed that it is required for both existing authorities and private parties to assume roles and responsibilities for upgrading the old housing while recently there have been continuous conflicts between development and preservation of the historic and cultural resources within the city and even the city identity also has been neglected by residents. In addition, it is necessary to take development conditions and resident's economic situation into consideration and introduce a wide range of methods for rearrangement, by turning the importance of housing upgrading to social rearrangement for the purpose of positive alternation.

In the case of Quine Mccluskey's methode for Boolean function minimization, we have to examine each bits of binary represented minterms. In this paper, cube relations between misterms that are represented by means of decimal number, and all sorts of rules for Boolean function minimization are described as theorems, and they are verified. And based on these theorems, the new fast algorithm for Boolean function minimization is proposed. An example of manual operation is sholvn, and the process is writed out by a FORTRAN program. In this program, the essential pl.imp implicants of the Boolean function that has 100 each of minterms including redundant minterms, are finked and printed out, (the more minterms can be treated if we take the more larger size of arrays) and the outputs are coincided with the results of manual operation.

This dissertation is try to figure out why chestnut belongs to kidney channel, from the viewpoint of five elements theory. After studying chestnut's property, flavor, channel tropism, main cure ability, prescriptions, shape, sweet, and prohibitions, I came to the following results. 1. Property of chestnut is warm and has no toxicity, so it is less related than kidney property. 2. Flavor of chestnut is salty and sweet, so it has some relation to kidney and spleen properties. 3. Channel tropism of chestnut enters mainly into kidney channel, and then spleen and stomach channels. 4. Chestnut controls kidney function of storing the essence of life, determining the condition of bone and marrow, conduction water metabolism, affecting reasoning activity, and controls activity of nine openings of body. It also has effects on functions of spleen, intestines and stomach. 5. Prescriptions including chestnut is similar to that of human brain, it is possible to reason out that chestnut has some relation to human brain. 7. As flavor of chestnut flower is similar to that of spermatic fluid, so it has som relation to kidney property. 8. As chestnut has property of blocking qi and it causes spleen, stomach and colon system to be confused, so it is suggested that persons with weakende spleen and stomach be not allowed to take in.

This study was conducted for the purpose of practice of nutrition education and dietary intake for college students. This survey was carried out through a variety of questionnaires by the subjects which consist of 249 male and 208 female college students in Seoul area. The results obtained were summarized as follows; 1. 75% of the subjects lived in their own houses; the monthly personal expenses were $110{\sim}200$ thousand wons. The appetite of the students who answered was normal in general. The pattern of dietary life shows that they take richer food at dinner than lunch and breakfast. 2. At school, 75% of students ate at the school cafeteria. Among several main dishes, rice was the most favorite food. Most of the subjects ate their lunch between 12 and 1 o'clock, and they spend approximately 11 to 15 minutes. Most of the students did not have lunch on time. The students ate lunch irregularly, because of the class schedule and poor appetite. 3. On weekends and vacations, 56% of the students ate lunch prepared by their mother at home. The two main reasons for skipping lunch during weekends and vacations were late breakfast and poor appetite. The frequency of eating out were $3{\sim}4$ times per week, because of social life and convenience of meal. 4. The majority of college students asked for the improvement of meal quality and the choice of menu in school cafeteria.

The importance of evaluation in design activity has been increased. Specially, it is necessary to take into consideration of user's needs as design criteria nowadays. Through these evaluations, the comprehensive quality of architectural design could be substantially improved and play the part of recycling at least in cases of theme similar structures. By a viewpoint of library patrons, there have increased many problems In library environment because more library patrons use the reference room for their study since reform of university education was carried out In 1981. Therefore, after post occupancy evaluation and spatial-planning matters of architecture are taken into consideration in this study, the problems of the plan-composition on the existing structure is pointed out and introduced the concept of post occupancy evaluation to grope the solution. With the question about users's needs and the state of use in the K-University Library, this study aims to investigate the actual use circumstance of space and maintenance of facilities as well as giving the most relevant alternatives instead of already existing one. This also intends to propose the essential date to meet the users' sociopsychological needs and environment innovation when planning the university library.
