A diagnosis program of damage-symptom caused by fruit tree pest was developed using Portable Document Format (Docucom PDF). To construct program structure, the damage patterns of plants cased by pests and the morphological rhararteristics of pests were sorted by plant organs. Diagnoses are rallied out by selecting a host species > document symptoms arranged by plant organs > comparing similar symptoms of pests using step by step menu through damage symptoms. In addition, pest information can be accessed either through the scientific or common name of the pest organism.

N/A Most authorities agree the higher incidence of gallstones among diabetic patient. Although many reports on gallstones or diabetes mellitus have been published, and actual correlation between gallstones and diabetes mellitus remains obscure. The purpose of this reports is to know the incidence of gallstone in diabetics and of diabetics in the patients with gallstone. Authors studied prospectively and clinically the diabetics in a group of 173 patients with gallstones and gallstone in a group of 98 diabetic patients who were admitted to Yonsei University Yong-Dong Hospital for the same period of April 1983 to May 1984. The results obtained are summarized as follow: The incidence of gallstone to general admission patients is 1.5% and the prevalence of diabetes mellitus to total in-patients is 0.8% The gallstone was found in 11.0% of diabetics and were diabetic 19.4% of patients with gallstones. The age of peak incidence of gallstones is 5th decade and female was more prevalent than male with the ratio of 1.37:1. The age of peak incidence of diabetes mellitus is 6 th decade and female is less prevalent with the ratio of 0.72:l.3, The most common characteristic finding of patients of gallstones with diabetes mellitus is symptomless(42.1%)4, There is no significant difference in serum levels of cholesterol and triglyceride between diabetic and non-diabetic groups or with and without gallstones. 5. Comparative study on location of stones revealed, 72.8% in gallbladder only, 12.7% in common bile duct only, 4. 6% in intrahepatic duct only, and remainders in multiple site. There is no significant difference in terms of location of stone between diabetic and nondiabetic group.

These work was accomplished with 6 day-old wheat(Triticum aestivum L.)seedlings to determine the effect of the inhibitors by sodium azide on in vivo nitrate reductase activity. When the sodium azide was treated according to each concentration (0.01∼100mM), the inhibition occurred greatly in the shoots and it occurred slightly in the roots of wheat seedlings. After treating with 1.0mM sodium azide, optimum pH was 7.0 both in shoots and roots. Both the shoots and roots of wheat seedlings was greatly inhibited in the second hours, when 1.0mM sodium azide was treated as a function of time. The inhibition in 10mM KNO_3 concentration appeared greatly, when 1.0mM sodium azide was treated with each concentration of KNO_3.

This work was accomplished with 6 day-old rye (Secale cereale L.) seedlings to determine the effect of the antibiotics by cycloheximide on in vivo nitrate reductase activity, protein and RNA content. The nitrate reductase activity by treating 0.1μM and 0.1 mM cycloheximide was lower than that of the control group. The optimum pH for the nitrate reductase of the control group was 7.6 in the range of pH 5.6-8.0, but, in the case of 0.1mM cycloheximide treatment group, the optimum pH was decreased to 6.8 within the weak the acid region. The protein content of shoot and root in the 0.1μM and 0.1 mM cycloheximide treatment groups were respectively found at the 96%, 82% level of that in the control group. In the higher cycloheximide treatment (0.1 mM CH), not only nitrate reductase activity and protein content but also RNA content was greatly decreased. In this fact, it was suggested that the 0.1 mM cycloheximide had affected on the RNA polymerase. On the basis of there results, it was concluded that the decreased nitrate reductase activity by treating cycloheximide occurred primarily according to the decreased nitrate uptake, and the decreased protein and RNA content depended upon the results of the direct and indirect effect of cycloheximide on the protein synthesis.

In order to obtain more realistic fracture resistance curve, many researchs are currently underway to introduce new parameter and to quantify the constraint effect. The objective of this paper is to investigate the relationship between the crack tip constraint effect (specimen size, specimen thickness, plane size, crack length ratio and side groove) and the fracture resistance curve. In this paper, fracture toughness tests were performed with various parameters. Test results show that the J-R curve is increased with increase in the plane size and decrease in the crack length and the J-R curve is decreased due to the side groove of specimen. In addition to the effects of the crack length and the plane size on the J-R curve are significant while the effects of specimen thickness and the specimen size on the J-R curve are insignificant.

The aim of this study is to identify the data traffic capacity of 3G mobile communication networks, especially of cdma2000-1X networks. Three-layered ON/OFF traffic model is used to describe the dynamics of data traffics and the process of data transmission such as packet scheduling. We construct a simulator fully incorporating packet handling process of cdma2000-1X data network as well as three-layered ON/OFF traffic model describing the behavior of source data traffics. To get influence of traffic parameters on performance measures, the extensive simulations were performed for several data sets which are obtained from real trace data or previous studies. The experimental results show that the engineered throughput satisfying QoS criteria is approximately 20% of total capacity. Finally, some proposals to improve the system capacity are followed.

This study was carried out to investigate several factors affecting embryo-genesis and organogenesis in vitro culture of rice embryo and the results indicated that Callus induction was the highest on LS agar medium containing 2.5㎎/L of 2.4-D and MS agar medium containing 2㎎/L of 2.4-D without vitamine. Zymograms of seed proteins determined by SDS-PAGE showed that they were quite similar, but only two major band were different between Gihobyeo and Milyang 23. One had a molecular weight of 40KD in Milyang 23 and another had a molecular weight of 55kD in Gihobyeo. After two weeks of culture, not-well induced Callus showed a distinct protein band having molecular weight of 20kD as compared to well induced Callus Calli on N60 and MSo media without auxin seemed to be embryogenic and showed similar batterns to seed proteins. Milyang 23 was higher in enzyme activity than Gihobyeo. Addition of abscisic acid on media resulted in increasing peroxidase activity and addition of BA increased on the malate dehydrogenase activity. A additional esterase isozyme band of pI 4.0 occurred at an early stage of rice Callus on medium with auxin. But Calli cultured on N60 and MSo media without auxin had similar esterase isozyme band patterns to seeds and Calli were embryogenic. Best plantlet formation was observed on medium with combination of 0.2㎎/L of IAA and 4㎎/L of BA. Embryogenic and organogenic Callus had characteristic protein bands of molecular weight of 40kD and 50kD determined by SDS-PAGE.
