This paper analyzed the obligations of the parties entering into an international leasing agreements, focusing on the Draft Common Frame of Reference (DCFR) Book IV, Part B. The lessor's obligations are as follows. i) The lessor must deliver goods to the lessee by the due date of delivery so that the lessee can use the goods on the starting date of the lease agreement. ii) The lessor must conform with the contract so that the goods meet the purpose of the contract at the start of the lease agreement and throughout the period of the lease agreement. iii) If the lessee returns the goods upon the termination of the lease agreement, the lessor must cooperate with the lessee. The lessee's obligations are as follows. i) The lessee must pay rent, which is the most critical obligation of the lessee. ii) The lessee must cooperate with the lessor so that the lessor can perform the obligation to deliver the goods and accept the goods of which the lessee shall take control. iii) The lessee shall perform fiduciary duties while it uses and makes profits from the goods, and when the lessor cannot take any measure to protect the object, the lessee must prevent damage. Further, if the lessor pays expenses that are not considered necessary expenses, the lessor may not be reimbursed and must accept the goods after delivery to preserve them. iv) The lessee must give notice to the lessor if there is a possibility that a third party can claim rights to goods or infringe upon the lessor's ownership while using the goods. v) At the end of the lease period, the lessee must return the goods to the lessor.

INTRODUCTION : Various types of organic reactions in the crystalline state, so-called "topochemical reaction", have been reported in this century." Among the reactions, [2+2] photocycloaddition of diolefin crystals are one of the most intensively investigated examples. In the topochemical reaction in a pure sense, the space group symmetry is perfectly preserved throughout the reaction as were demonstrated by the crystalline-state photopolymerization of 2,5-distyrylpyrazine (2,5-DSP) and photodimerization of propyl $\alpha$-cyano-4-[2-(4-pyridyl) ethenyl]cinnamate. 2,5-DSP was initially prepared by Franke and in 1958 Koelsch and Gumprecht described briefly in their article of diazine-derivatives that it was found that the compound (2,5-DsP) was converted into a colorless insoluble polymer (\ulcorner) dec. 331~331$\circ$ when the solid was exposed for a few hours to ultraviolet light. Wright described in his book as if Koelsch and Gumprecht had investigated both the structure of the photoproduct and the crystal structure 2,5-DSP in detail. However, in the paper, they have not described any study on chemically correct analysis and crystallography of the resulting photoproduct at all. In 1967, one of present authors (M. H.) independently made the same observation as Franke that brilliant yellow crystal of 2,5-DSP was converted into powdery white substance under the sunlight in the course of a preparative study of pyrazine-2,5-dicarboxylic acid from 2,5-DSP. He investigated this phenomenon and concluded for the first time that a linear highmolecular-weight polymer crystal ([$\eta$] > 3.0 in $CF_3COOH$ solution) with recurring cyclobutane units in the main chain, had been produced from 2,5-DSP crystal by the action of sunlight.on of sunlight.

According to "A guide Book to Highway Design", most road elements are chosen based on a certain design speed in order to ensure obtaining safe and smooth traffic operating. However, road safety in practical way is corelative to not only all element of roads but also road shape, for example, between straight line and curves line and between curved lines. Also, it is relates to alignments such as horizontal alignment, vertical alignment, and cross section. That is, the practical road design should be examined in both sides of 3 dimension and consecutiveness as the practical road is a 3-dimensional successive object. The paper presents a concept for acceleration to evaluate consistency of road considering actual road shape on 3-dimension. Acceleration of vehicle is influential to road consistency based on running state of vehicle and state of drivers. Especially, the magnitude of acceleration is a quite influential element to drivers. Based on above, the acceleration on each point 3-D road can be calculated and then displacement can be done. Computation of acceleration means total calculation on each axis.

Natural disasters caused by climate change are increasing globally. There are few studies on the quantitative analysis methods for predicting damages in the island area due to sea level rise. Therefore, it is necessary to study the damage prediction analysis method using the GIS which can quantitatively analyze. In this paper, we analyze the cause and status of sea level rise, quantify the vulnerability index, establish an integrated terrestrial modeling method of the ocean and land, and establish a method of analyzing the damage area and damage scale due to sea level rise using GIS and the method of making the damage prediction figure was studied. In order to extract the other affected areas to sea level rise are apart of the terrain model is generated by one requires a terrain modeling of target areas are offshore and vertical reference system differences in land, found the need for correction by a tidal observations and geoid model there was. Grading of terrain, coastline erosion rate, coastal slope, sea level rise rate, and even average by vulnerable factors due to sea level rise indicates that quantitative damage prediction is possible due to sea level rise in the island area. In the case of vulnerable areas extracted by GIS, residential areas and living areas are concentrated on the coastal area due to the nature of the book area, and field survey shows that coastal changes and erosion are caused by sea level rise or tsunami.

To predict the fatigue life of the Hub Bearing Unit(HBU), preload effect and initial axial clearance have to be considered. Various theory and equations for the HBU design used in the passenger car are well developed in many literatures. But most design hand book for bearings or bearing catalogues do not consider the initial axial clearance and preload effect. So there are limits and difficulties to use those data in actual bearing design. To consider the preload effect and initial axial clearance, complex elliptic integrals and nonlinear equations are involved. These equations are difficult to solve during the design process. In order to solve these problems effectively, a program is developed to solve these equations reliably and to help the designer in obtaining the performance data of the HBU such as load distribution, maximum contact stress and fatigue life. The preprocessor of the program helps users to prepare the input data through a dialog box and the post processor makes graphical presentation of the result. In this paper, theoretical and numerical background for the prediction of the fatigue life of the HBU is explained. A simple example is presented to show the usefulness of developed program.

This paper focused on three drawbacks exposed in subject matter related to solid figures in elementary school math textbook. First, general solid figure are introduced before rectangular parallelepiped and cube in fifth grade math textbook, and prism and pyramid in sixth grade math textbook are introduced. Second, the process of abstraction from concrete objects to solid figures is insufficient in sixth grade math textbook. Third, some definitions in subject matter related to solid figures are inconsistent and ambiguous. The following four suggestions can be put forward as a conclusion based on these results. First, subject matter in textbooks must be correspond with that in curriculum. Second, it is necessary to inform teachers of range of subject matter through teachers guide book and manual for curriculum definitely. Third, each grade subject matter in math textbooks must be reexamined. Fourth, regular modification of math textbooks must be possible institutionally.

Theses and dissertations are works embodying results of original research on a subject and substantiating a particular point of view by usually graduate students, as a degree requirement. Most theses and dissertations are not controlled by commercial publishing interests, and thus are not obtained in book-form by most libraries. Due to their lack of physical and ready availability and information about the contents, theses and dissertations have been extremely underutilized sources of information without distinction of nations. The goal of this paper is to provide the current informations on the distribution and management systems of theses and dissertations in Foreign and Korea. The findings of this study will provide the basis for developing an standardized management model of theses and dissertations that meets the needs of researchers, students, and librarians in Korea.

by A.C. Clairaut is the first geometry textbook based on the historico-genetic principle against the logico-deduction method of Euclid's This paper aims to recognize Clairaut's historico-genetic principle by inquiring into this book and to search for its applications to school mathematics. For this purpose, we induce the following five characteristics that result from his principle and give some suggestions for school geometry in relation to these characteristics respectively : 1. The appearance of geometry is due to the necessity. 2. He approaches to the geometry through solving real-world problems.- the application of mathematics 3. He adopts natural methods for beginners.-the harmony of intuition and logic 4. He makes beginners to grasp the principles. 5. The activity principle is embodied. In addition, we analyze the two useful propositions that may prove these characteristics properly.

To analyze dialy meal of royal meal, studied Bankwa Sang(Fruit Table) were on record Wonheng Ulmyo Jungri Euigwae (1795). Historic book 'Jungri Euigwae' described the king's visit to his father's royal tomb 'Hyun Neung Won', during the domain of Cheung Jo, the 22nd king of Choson Dynasty. The results obtained from this study areas follows. The fruit table, which similar in concept to desert in the west but quite different in service, was prepared for a guest. The table consisted of two kinds of trays, on which serveral kinds of fruit were stacked to a height of between 4 chon (4寸 : about 12 cm) and 1 chuk(1尺 : about 30.3 cm) according to Korean measurement system. The table was decorated with beautiful artificial flowers made of paper and silk. The number of sets to be arranged on the table were different according to the royal status of the eater: 12 sets-25 sets for king's mother, 7 sets-11 sets for the king. Soy sauce mixed with vinegar and pine-nu meal, mustard were ruled out from kind of sets. Kinds of dishes served with a meal generally were noodles (麵), soup (湯), fried fish (煎油花), fried meats and vegetables (花陽灸), slices of raw fish (魚膾), minced raw meat (肉膾), slices of boiled beef (片肉), stew (蒸), rice cake (餠), sweet rice dish (藥飯), patterned savory cake (茶食), fried cake made of wheat flour, honey and oil (藥果), fried glutinous rice cake (强精), various fruits preserved in honey (正果), sugar candies (各色糖), fruits (果物) honey (淸), soy sauce mixed with vinegar and pine-nut meal (醋醬), mustard (莽子).
