This is the survey on the actual condition about the managing of headings in library cataloging. KCR4, the standard rules for the library cataloging in Korea, has no rules for the main entry headings and uniform headings. But the cataloging records are not standardized because a lot of libraries in Korea use the main entry headings and uniform headings yet. A structural revision of KORMARC is required in order that all library follow the rules on the KCR's main entry headings. And the rules for uniform heading used until KCR4's policy about the heading is decided according to international trends are needed.

The purpose of this study is to investigate the distinctiveness and problem areas in cataloging rules of sound recordings. In this study, therefore, the characteristics and kinds of sound recordings and the cataloging rules related to sound recordings in non-book cataloging rules are examined first as the backgrounds. Then the sources of information, general material designation, physical description, choice of headings, and uniform titles in ISBD(NBM)·AACR2R·AECT4 and KORMARC(NBM) are analyzed. And the special issues and some problems to be considered in cataloging of sound recordings are presented.

Locating function of a particular item is more of added entry than a main entry heading. This function was expanded especially in the machine readable cataloging by introducing the control number and standard bibliographic number. Assembling function of the main entry heading is on a level with that of cross reference and notes, added entries, uniform headings. Links among all variant forms of a heading in hypercatalog will be made for collocating of all publications of a given author. The link of bibliographic records in this catalog can be freed from the dependence on standardized heading form. The function of the catalog is not affected even though by abandoning the concept of main entry heading. Further efforts should be made to raise users' finding opportunities through expansion of acces points and linking devices among related records.

This study analyzed guidelines and instructions for access points representing works and expressions in RDA. The preferred title for the work is used as the basis for constructing an authorized access point to represent a work or expression. If applicable, the authorized access point is constructed by combining the preferred title for the work to the authorized access point for the identity with principal responsibility for the work. The variant titles for the work are used as the basis for constructing variant access points to represent a work or expression. If the authorized access point is constructed by combining the preferred title for the work to the authorized access point for the identity responsible for the work, the variant access points are constructed by combining the variant titles for the work to the authorized access point, and by using only the preferred title for the work. Besides, RDA provides instructions to construct the controlled access points for special works like musical works, laws, religious works and others, but the general principles for these works are same as the above instructions. The authorized access points for works and expressions in RDA are almost same as the main entry headings in AACR2.

It has been noted that an accurate estimation of wind loads on offshore structures such as an FLNG (Liquefied Natural Gas Floating P roduction Storage Offloading Units, LNG FPSOs) with a large topside plays an important role in the safety design of hull and mooring system. Therefore, the present study aims to develop a computational model for estimating the wind load acting on an FLNG. In particular, it is the sequel to the previous research by the author. The numerical computation model in the present study was modified based on the previous research. Numerical analysis for estimating wind loads was performed in two conditions for an interval of wind direction (α), 15° over the range of 0° to 360°. One condition is uniform wind speed and the other is the NPD model reflecting the wind speed profile. At first, the effect of sand-grain roughness on the speed profile of the NPD model was studied. Based on the developed NPD model, mesh convergence tests were carried out for 3 wind headings, i.e. head, quartering, and beam. Finally, wind loads on 6-degrees of freedom were numerically estimated and compared by two boundary conditions, uniform speed, and the NPD model. In the present study, a commercial RANS-based viscous solver, STAR-CCM+ (ver. 17.02) was adopted. In summary, wind loads in surge and yaw from the wind speed profile boundary condition were increased by 20.35% and 34.27% at most. Particularly, the interval mean of sway (45° < α <135°, 225° < α < 315°) and roll (60° < α < 135°, 225° < α < 270°) increased by 15.60% and 10.89% against the uniform wind speed (10m/s) boundary condition.
