As more application programs have graphic functions, standards in the computer graphics are becoming important. To develop a computer aided design and production system for ships, which would be used by different shipyards, a graphic library should be chosen as a standard. Existing ISO graphic standards and de facto industrial standards are surveyed. They are, to name some of them, GKS, PHIGS, X-Window, PEX, PDES, and STEP. GKS and PHIGS concern about the application programmer's interface. Others handle the device interface. PDES and STEP are to standardize the graphical data transfer between heterogeneous systems. Their inter-relations are investigated. Some preliminary suggestions for the choice of graphic standards are included in this paper.

The domestic market of oriental herbal cosmetics has rapidly grown in the last few years. In this study, we investigated female consumers' cosmetics-buying behavior to know their appreciation of oriental herbal cosmetics. We also tried to deduce the strategies for growth and development of the oriental herbal cosmetics market in the future. A survey was conducted with women ranging in age from 20 to 50, who resided in Seoul; a total of 400 questionnaires were distributed and then 344 copies of those. were collected and analyzed statistically. This study provides basic information about the present status of oriental herbal cosmetics market and the real state of the cosmetic consumption. The consumers needs identified in this study, provides basic data in setting a marketing strategy for the oriental herbal cosmetics market.

By using the test fungus Macrophomina phaseolina, residues of triadimefon were found in straw collected after harvest from sprayed plants of wheat varieties Kharchia and Lal Bahadur but grains contain no such residues. Thin layer chromatographic method was developed to detect residues of the fungicide which was found to be present in straw of sprayed plants of both the varieties. No residues could be detected in grain samples. It was found that triadimefon was converted in triadimenol in/to host.

This paper proposes an dffcient method for test pattern generation.Current test pattern genration systems generate a test vester for fault $F_{i+l}$ independently of the computation previously done for faults F1,F2...,Fi The proposed algorithm generates a test vector for fault $F_{i+l}$ by inheriting the test vector for fault Fi. A new test vector is grnerated from inherited values by gradually changing the inhderited values .The inherited values may partially activate a fauog and propagate the fault signal,Normally,this reduses the number of decision steps and backtracks in the second search.Experimental results for well-Known benchmark circuts show that the proposed algorithm is very efficient with small backtrack kimit;in combination eith other algorithms,it is very efficient for arbitrary backtrack limits.

Observations on reproduction of Rhodochorton purpureum (Lightfoot) Rosenvinge (Acrochaetiaceae, Rhodophyta) was carried out with plants from Hokkaido, Japan. This species produces no monosporangia both in nature and culture, even though it does tetrasporangia commonly. The plants from Nemuro produce neither sporangia nor gametangia, and thus vegetative reproduction is the only known way to propagate themselves. It is suggested that the vegetative reproduction occurs in nature by fragmentation of vegetative filaments after development of a rhizoid. Several different modes of rhizoid production are described. The plants from Akkeshi and Oshoro (I) produce tetrasporangia that develop into plants producing only tetrasporangia. The plants from Muroran and Oshoro (II) produce tetrasporangia that develop into gametophytes. Gametophytes of R. purpureum from Muroran produce tetrasporangia as well as spermatangia or carpogonia. Such tetrasporangia on gametophytes are presumed to be mitotic.

A new generation of commercial satellites like IKONOS, SPOT-5 and OrbView-3,4 will have improved features, especially an higher geometric resolution with a better dynamic radiometric range. In addition high precision orbital position and attitude data will be provided by the on-board GPS receivers, IMU(Inertial Measurement Units) and star trackers. This additional information allows for reducing the number of ground control points. Furthermore this information enables direct georeferencing of imagery without ground control points. In our work mathematical models for calculating the satellite orbital parameters of SPOT-3 and KOMPSAT-1 were developed and can be easily extended to process images from other high resolution imaging systems as they become available.

Planning distributed manufacturing logistics is one of main issues in supply chain management. This paper proposes a hybrid heuristic approach for the Multi-Level, multi-item Capacitated Lot Sizing Problem (MLCLSP) in supply chain network. MLCLSP corresponds to a mixed integer programming (MIP) problem. With integer variable solutions determined by heuristic search, this MIP problem becomes linear program (LP). By repeatedly solving the relaxed MIP problems with a heuristic search method in a hybrid manner, this proposed approach allocates finite manufacturing resources fur each distributed facilities and generates feasible production plans. Meta heuristic search algorithm is presented to solve the MIP problems. The experimental test evaluates the computational performance under a variety of problem scenarios.

The purpose of this study is to analyse the characteristics and limitations of community information services and to explore an activation strategies. Included in this study are as follows: (1) investigate what is an appropriate representative term through the history of terminology related to community information services, (2) examine how community information services are operated in the regional central libraries from the librarian's perspective, (3) suggest the directions of community information services. The data were collected literature studies and interview with 20 librarians in regional central libraries.

The CNN (convolutional neural network) based single degradation restoration method shows outstanding performance yet is tailored on solving a specific degradation type. In this paper, we present an algorithm of multi-degradation classification and restoration. We utilize the CNN based algorithm for solving image degradation classification problem using pre-trained Inception-v3 network. In addition, we use the existing CNN based algorithms for solving particular image degradation problems. We identity the restoration order of multi-degraded images empirically and compare with the non-reference image quality assessment score based on CNN. We use the restoration order to implement the algorithm. The experimental results show that the proposed algorithm can solve multi-degradation problem.
