밤의 害蟲 Dichocrocis punctiferalis Guene′e의 防除에 關한 硏究

成煥祥 진주교육대학교 1983 論文集 Vol.27 No.1

As a clue to determine the proper extermination period of chestnut vermin, Dichocrodis punctiferalis Guene´e, the ecological studies on the relationship between oviposition of the vermin on the chestnut bur and the growth of chestnut bar were carried out from 1982 to 1989. The results are as follows: 1. The oviposition periods of early matured chestnut were from 2nd to 3rd 6th of February and from last 6th of July to 2nd 6 th of August. In the latter period the oviposition was shown to be highest rate. For the middle and late matured chestnut oviposition was generally observed through the days of August and shown to be highest peak from 2nd to 3rd 6th of August. 2. This chestnut vermin oviposits on the chestnut bur in over 2 cm diameter. Oviposition rate showed highest on the chestnut bur in 6~8cm diameter and the damage rate was about 60% over the total amount of oviposition. 3. Considering the relationship between the oviposition and the growth of chestnut bur, 3 times pesticide sprayings in the last third of July, in the first third of August and in the last third of August were considered mast effective. However, when working labor was taken into consideration, 2 times pesticide spraying in the last third of July and in the first third of August when the oviposition rate showed highest peak was the most adequate.

ATM 망에서 원격제어 에이전트 시스템을 위한 연결 설정 방법에 관한 연구

최길환,배상현 조선대학교 통계연구소 2000 統計硏究所論文誌 Vol.2 No.1

The ATM networks must accommodate diverse types of applications with different quality of services(QoS) and traffic characteristics, which may be require point-to-point connection or multipoint connection. Thus, in order to increase the utilization of the networks and satisfy the Qos's of each traffic type, some types of traffic control schemes must be adopted in ATM networks. However, they have problems in establishing connections over multiple sub-networks, such as no end-to-end connections, transmission delay due to ATM address resolution, no QoS protocols. The major design consideration of this remote control agent system is that the ATM API is included by the existing network. In this work, we study the agent architecture based on the ATM nets and the network control capability to allow creation of more intelligent service as well as existing broadband multimedia service. We propose a new connection management scheme in the thesis to improve the connection management involved. In this thesis, the service agent connection for the ATM nets are proposed and their performances are analyzed. In this thesis, the main objective of this dissertation work is to investigate the performance of traffic control schemes for ATM agent connection.

成煥祥 진주교육대학교 1968 論文集 Vol.2 No.1

To ascertain the effects of three essential elements of fertilzer on the occurrence of whitecore Kernels of rice, experiments were carried out by means of the pot culture, using the Variety, Kokyangdo. The amounts of cach element added to a pot (ca 1/5,000a) were 0.2g, 0.5g, and 0.8g, according to the experimental plots. Commercial fetilizers used were ammonium sulphate, Calcium superphosphate and potassium chloride. A half amount of these fertilizers was applied to the pot just before transplanting as the basic fertilizer and the other half of them at the time of eardifferentiation as the Top dressing one. The results are summarized as fellows; (1) Nitrogen gives the most powerful influence on the production of white-core Kernels, that is, with The increased amount of its application, talc occurrence of white-core Kernels in The ear is remarkably improved, being independent of the amounts of other elements, In contrast to the effect of nitrogen, the more phosphorus is applied, the less white-core Kenels are produced. The effect of patassium is not clear. (2) The effect of each element is not Simple but complicated by the amounts of other elements, Especially, an abundant application of phosphorus tends to eliminate the nitrogen effect, but this action of phosphorus may somewhat be depressed by heavier application of nitrogen or potassium

인터넷상에서 Ontology를 이용한 정보의 분류와 획득을 위한 지능형 에이전트의 설계

양성기,이광옥,최길환,오창윤,배상현 조선대학교 통계연구소 2000 統計硏究所論文誌 Vol.2 No.1

In this paper, we propose a new method of information gathering and text classification based on Internet. The number and diversity of information resources on the internet is increasing rapidly. As more information become available on the internet, it becomes increasingly difficult to acquire knowledge we need. A number of tools are available to help people search for the information they need. However, These tools are unable to interpret the result of their search due to lack of knowledge of domain. We need more intelligent system which facilitates personal activities of producing information such as surveying, writing paper and so on. We Implemented a system called ⅡRS(Intelligent Information Retrieval System) which helps people to acquire knowledge form information resources on the internet by gathering information and classification texts. It specifies the common background knowledge shared by the user and ⅡRS, allow ⅡRS to make inexact match between the user's request and the candidates, assigns user-oriented categories. We tested ⅡRS for gathering pages on the WWW and classification articles on the network news. The result of the experiments indicated that the ontology based approach enable us to use heterogeneous information resources on the internet.

Bacillus sphaercus 1593 K-5와 ts-U311의 총 세포 단백질을 전기영동적인 방법으로 비교했다. 1. B. sphaercus 1593 K-5와 ts-U311의 총 단백질간에는 분자량과 등전점에서 많은 차이가 있었으나,동일 균주에서는 성장온도 변화에 따른 단백질 양상에서 거의 차이가 없었다. 2.B.sphaericus 1593 K-5는 분자량이 최고 225Kd에서 최저 13Kd에 걸쳐 총 26개 밴드가 분리되었고,ts-U311 은 최고 220K 달톤에서 최저 13.5K달톤까지 24개 밴드가 분리되었드며, 두 균주의 단백질은 분자량이 150,94,77,57,40,32,19Kd인 곳에서 존재유무와 양에 차이가 있었다. 3. B.sphaericus 1593 K-5 ts-U311은 pH 4.2에서 pH 4.8 사이에서 등전점을 가지는 단백질이 이차원젤상에 나타나지 않았으나, B.sphaericus 1593 K-5는 진하게 염색된 4번과 5번 단백질 점이 나타났다. 4. 이차원젤 상에서 두 균주의 단백질 종류의 차이점은 다음과 같다. 4번,5번,12번,19번,20번,21번은 B.sphaericus 1593 K-5에 존재하나 ts-U311에는 없었고, 36번,37번,38번,39번은 ts-U311에는 존재하지만 B.sphaericus 1593 K-5에는 없었다. 또한,3번,6번,27번,28번,29번,35번은 단백질의 양에서 차이가 있었고,여러 곳에서 전개위치가 약간씩 다르게 나타났다. 5.B.sphaericus 1593 K-5의 단백질 중에서 분자량이 150Kd인 것이 독소인 것으로 확인되었고 ts-U311에서는 이 단백질이 없었다. 생체검정시험에서도 B.sphaericus 1593 K-5는 강력한 독성을 보였지만 ts-U311은 전혀 독성이 없었다. Protein syntheses by B. sphaericus 1593 wild type strain and ts-U311 mutant were studied by gel electrophoretic analysis. The protein patterns of the two strains were different in the molecular weight bands of 150,94,77,57,40,32 and 19 kilodaltons by SDS-polyacryl-amide gel electrophoresis analysis. In the isoelectric-focusing the proteins from B. sphaericus ts-U311 were not banded in the pH ranges 4.2 to 4.8 In the analysis of two-dimentional polyacrylamide gel electrophoresis the wild type strain had number 4,5,12,19,20 and 21 sptted proteins, but the ts-U311 did not. Number 36,37,38 and 39 spotted proteins were produced from the proteins of ts-U311,but the wild type strain did not. The 150 Kd protein from B.sphaericus wild type strain was toxic to the larvae of Culex pipiens, but it was not produced from the B.sphaericus ts-U311.

광학적 Faraday Rotator용 Pulse Forming Network의 제작 및 시험

金允溟,羅勝煥,李相洙,安明浩 단국대학교 1990 論文集 Vol.24 No.-

An optical Faraday rotator is designed with the HOYA FR-5 rotator glass and the pulse forming network(PFN). The polarization of the traveling light rotates 45° in this glass when magnetic field intensity is about 3.0×10^5 AT/m. The current of 2.25kA flowing in the coil of the 9cm inside diameter, 29cm long and 41 windings generates this magnetic field. This current of 84μsec duration can be obtained with a PFN. The network is analyzed numerically to find the relevant circuit parameters, initial charging voltage of capacitors and the voltage/current waveforms. The measured waveforms of the assembled PFN are in good agreement with the computed waveforms.
