As the storage capacity of a computer system is rapidly increasing and the cost of computer hardware is decreasing continuously, users can easily manage multimedia data on the personal computer. Especially, various image view programs are widely used to manage image files at the present time. However, since most of these programs do not use a database management system(DBMS), it is very difficult for users to use them efficiently. In this paper, we designed and implemented a Digital Album by using an object-relational database management system, called PARODY(Persistent, Almost, Relational Object Database sYstem) that implements a persistent object database with a relatively simple interface to its C++ class library. Since PARODY is used as a data storage manager of the Digital Album, users can manage(i.e., insert, update, and delete) an image database and search for the required image data from the image database easily. In addition, we use OWL(Object Windows Library) of Borland C++ to implement the user interface of the Digital Album efficiently.
컴퓨터와 작업자의 통합 생산관리 시스템 구현을 위한 객체지향형 설계

We design an integrated production management system that incorporates management tasks of procurement of materials, production, and marketing. It includes MRP simulation on small or medium sized companies, design of databases, and definition of relevant objects in production environments. The system has been designed using object-oriented programming concept not only to represent the real-world situation easily, but also to help system integration. Graphics-User Interface(GUI) is also employed for the efficiency of production plannig.

The effects of six sugar resources (fructose, glucose, sucrose, trehalose, raffinose and honey) on the longevity, oviposition performance and nutrition levels of Meteorus pulchricornis, a thelytokous larval endoparasitoid of the common cutworm Spodoptera litura were examined under laboratory conditions. Female adults of M. pulchricornis fed 1 M fructose, glucose, trehalose or sucrose solutions survived longer than those fed on other sugar solutions or water. When provided with honey or sucrose solutions, the female parasitoids laid more offspring than those fed other sugar diets or the control. The body size of offspring driven from honey-, fructose-, sucrose-, and glucose-fed females, along with water-fed group, were larger than the trehalose- and raffinose-fed females. However, the emergence rates of all offspring generated from different sugars- and water-fed females were similar. When separately given honey, sucrose or fructose, M. pulchricornis females accumulated fructose at a higher level than the other groups. Parasitoid wasps fed trehalose solution accumulated the highest level of total sugar. Glycogen levels and lipid content were highest at emergence and then decreased across all diets. In addition, females fed on trehalose had the highest level of glycogen compared to other sugar diets and water control regardless of emergency level. Females fed trehalsoe, fructose, and glucose solutions had a higher level of lipid than those fed other sugar solutions and water at life end. The outcome of this study can benefit both laboratory rearing and management interventions that improve sugar sources for the parasitoid in the field.

In this study, bacterial strains were isolated from soils from 30 locations of Samcheok, Gangwon province. Of the isolated strains, seven showed potential plant growth promoting and antagonistic activities. Based on cultural and morphological characterization, and 16S rRNA gene sequencing, these strains were identified as Paenibacillus species. All seven strains produced ammonia, cellulase, hydrocyanic acid, indole-3-acetic acid, protease, phosphatase, and siderophores. They also inhibited the mycelial growth of Fusarium oxysporum f. sp. radicis-lycopersici in vitro. The seven Paenibacillus strains enhanced a range of growth parameters in tomato plants under greenhouse conditions, in comparison with non-inoculated control plants. Notably, treatment of tomato plants with one identified strain, P. polymyxa SC09-21, resulted in 80.0% suppression of fusarium crown and root rot under greenhouse conditions. The plant growth promoting and antifungal activity of P. polymyxa SC09-21 identified in this study highlight its potential suitability as a bioinoculant.

One new clerodane-type furanoditerpenoidtinosinoid A ( 1 ) and nine new nor-clerodane analogs tinosinoids B–J ( 2 − 10 ) have been isolated from the stems ofTinospora sinensis . The structures of the new compoundswith absolute confi gurations have been elucidated by spectroscopicmeans, including MS, NMR and ECD techniques,as well as chemical correlation. Compound 1 is a rare sulfurcontainingclerodane diterpenoid incorporating a 2-mercaptoethanolunit via a thioether bond, while compounds 4 / 5and 9 represent two pairs of unusual equilibrium regioisomersthrough an interesting intramolecular transesterifi cation. Our bioassays established that 1 and 8 displayed moderateantiproliferative eff ects against two human tumor celllines, and 9 and 10 showed signifi cant α -glucosidase inhibitoryactivities. A kinetics study revealed that compound 10was a noncompetitive α -glucosidase inhibitor, and its possiblebinding mode to the enzyme was further probed bymolecular docking experiments.
