This study was performed to develope a money management education program for elementary school students graded from 3 to 6 in order to enhance their money management skill. Based on the developmental stages of the children, this program covered five financial issues such as value of money, financial planning, allowance planning, saving and investment, and consuming and purchasing. Total 15 specific education programs were developed. The contents included in each program were value of money & economic circulation, types of money and the importance of money management, the issues related on choice and resource use, long-term and short-term planning, the relationship between occupation and earnings, career planning, budgeting, the reasons and types of saving, understanding of interest, investment methods, the functions of market and trade, intra family income distribution, consumptions, and consumer decision making process.

The nation's birthrate has been rapidly falling. The purpose of this study was to explore the factors related to low birthrate, by analyzing TV dramas dealing with childbirth and rearing. Content analysis is well suited to research probing widespread cultural notions or behavior. If any part or all of the dramas discussed an aspect of childbirth and rearing, we recorded verbatim quotes and paraphrased some specific points. Using the technique of multiple observers, inter rater as well as intra rater reliabilities were measured. The results showed that emergent themes in TV dramas on low birthrate are social environment, family context, and value changes. The conclusions and implications of these findings are discussed.

Resricted opening of the mouth in children can be derived from a variety af extra and intra articular causes. A 5-year-old female patient with an elongated right coronoid process and with congenital missing teeth came to clinic for wearing of esthetic denture. A proper medical consultation and laboratory test had done for assessment a systemic syndrome related to her dental anomalies. The result was that her systemic findings dindn't accord specific signs and symptoms of Hallermann-Streiff syndrome. Unilateral coronoidectomy was fulfilled to improve mouth opening and subsequently endodontic and restorative procedure. Maxillary partial denture was delivered for esthetic problem. The periodic recall medical/dental check-up are recommended.

Electrofusion of cabbage protoplasts was performed with a developed equipment which consists of a parallel wire electrode, a AC field generator, and a pulse generator. Exposure of protoplasts to an alternating current field of 450 KHz causes attraction to each other which leads to chains of protoplasts extending from the electrode. Intra-specific protoplast fusion was effectively induced within the pearl chains by the additional application of a single high-intensity DC square wave pulse of 1 KV/cm for 1-3 msec. To improve the performance, micro fusion electrode fabricated from the semiconductor technology and microcontroller based field an, d pulse generator was proposed. The viability of protoplasts after an application of electric field at optimum condition was reduced by only 5 % compared with that of pre-application. A prototype of fusion electrode, which consists of insulator-structure, was successfully fabricated by using photosensitive polyimide.

The morphological characteristics of the Korean Scopolia japonica Maxim., commonly known as 'Mi-chi-gwang-i-pul' in Korean, were re-evaluated in comparison with results from previous research, while the distribution map was formulated according to existing flora and voucher specimens. The result of the re-evaluation has shown that there are some distinctive discrepancies compared to the previous reports of some characteristics such as the color of the basal stem, numbers of lateral veins, apex shape of calyx and corolla including the color of corolla. The Korean Scopolia japonica Maxim is found throughout Korea except Jeju-do province. The intra-specific species such as S. parviflora (Dunn.) Nakai, S. lutescens Y.N. Lee and S. kwangdokensis Y.N. Lee were treated as synonyms of S. japonica Maxim. in this research.

An optimum design has been performed to maximize specific energy (SED) of composite flywheel rotor for energy storage system. The flywheel rotor is assumed to be an axisymmetric thick laminated shell with a plane strain state for structural analysis. For the structural analysis the centrifugal force is considered and the stiffness matrix equation was derived for each ring considering the interferences between the rings. The global stiffness matrix was derived by integrating the local stiffness matrix satisfying the conditions of force and displacement compatibilities. Displacements are then calculated from the global stiffness matrix and the stresses in each ring are also calculated. 3-D intra-laminar quadratic Tsai-Wu criterion is then used for the strength analysis. An optimum procedure is also developed to find the optimal interferences and lay up angle to maximize SED using the sensitivity analysis.

A harpacticoid copepod, Sinamphiascus dominatus Mu & Gee, 2000 is re-described from the sandy bottom in off Jeju Island of Korea. The genus Sinamphiascus was established with single species, S. dominatus from the Bohai Sea, China. The main diagnostic characters of the specimen from Korea are well matched with the original description, although it has minor discrepancies including the lengths and ornamentation of setae in leg 6 of both sexes, shape of the base on furcal setae and teeth number of labrum in female. However those discrepancies are regarded to the intra-specific variations. This is the first record of genus Sinamphiascus in Korean waters.

The occurrence of inclusion body hepatitis was confirmed for the first time in Korea from chickens submitted for diagnosis to this Institute from a farm located in the vicinity of Anyang. The chickens showed no specific clinical signs except for moderate anemic conditions. At autopsy, livers were swollen and mottled with numerous stellate subcapsular hemorrhages and necrotic foci. Severe nephritis and catarrhal enteritis were also seen. The most notable microscopic changes were seen in the liver. These included eosinophilic intra-nuclear inclusion bodies in the hepatocyes, massive hemorrhages and necrosis and fatty changes in the liver parenchema.

Among several diagnostic tools for clonorchiasis (Clonorchis sinensis infection), radiologic examinations are commonly used in clinical practices. During the 2 past decades, many reports regarding imaging findings of clonorchiasis were introduced. The basic imaging finding of clonorchiasis is diffuse dilatation of the peripheral intra-hepatic bile ducts, without dilation of the large intrahepatic or extrahepatic bile ducts. By this finding, however, active clonorchiasis cannot be differentiated from cured infection. Some recent radiologic studies suggested specific findings of active clonorchiasis. Besides direct demonstration of worms, increased periductal echogenicity on sonography and periductal enhancement on dynamic contrast-enhanced CT or MR imaging possibly represent active clonorchiasis. Those images of the liver clonorchiasis are known to be correlated with worm burdens (EPG counts) in their frequency and also severity. The images of cholangiocarcinoma associated with clonorchiasis show both the tumor with obstruction images and diffuse dilatation of the peripheral intrahepatic bile ducts. Radiological images can be a good practical alternative diagnostic method of clonorchiasis.

As a potent antigen presenting cells and a powerful inducer of antigen specific immunity including cytotoxic T cell activity, dendritic cells(DCs) are being considered as a promising anti-tumor therapeutic module. Unlike solid tumors, leukemia is the hematologic malignancy involving immune effector cells. The expected usage of DCs in leukemia is the treatment of minimal residual disease(MRD) after the remission or stem cell transplantation. In this study, syngeneic leukemia cells were inoculated intra-venously into the mouse (WEHI-3 into the Balb/c), and the autologous tumor cell lysate pulsed DCs were injected as a therapeutic module twice in two weeks.
