Ni-Zn 페라이트의 透磁率과 磁氣抵抗에 미치는 添加物의 影響
강재덕,최희태,서강수,신용진 明知大學校 産業技術硏究所 1990 産業技術硏究所論文集 Vol.9 No.-
This paper is studied on the effects of additive of permeability and magnetic reluctance of Ni-Zn ferrites. Ni-Zn ferrites was composed of 20mo1% NiO, 30mo1% ZnO, 50mo1% Fe₂O₃, and 0.0025n1o1%, 0.005mo1%, 0.01 mol% ??, Bi₂O₃, ?? were used as minor additive Sintering was carried oui at 1100℃. As results from the experiments, the initial permeability was proportional inversely to magnetic reluctance. It was observed that the better magnetic properties of initial permeability anti magnetic reluctance could be achieved by the additive ??.

A study of 118 autopsy cases associated with medical care in 1990 was present according to the medical department, the mode of treatment and the cause of death. The Pediatrics showed the highest rate (25.4%), followed by the Obstetrics & Gynecology (22.9%), and Internal medicine (20.2%). According to the mode of treatment, medical accidents during operation and anesthesia were 29 cases (24.6%) with highest rate in Obstetrics & Gynecology (13 cases), 38 cases (32.2%) were during medication and/or injection with highest rate in Internal Medicine (18 cases), and 51 cases (43.2%) were during general medical practice with highest rate in pediatrics (19 cases). The most prevalent cause of death was the disease of respiratory system (34.9%, 30 cases) and the diseases of cardiovascular and urogenital system accounted for 31.4% and 11.6% respectively. The main cause of death in Internal medicine was the disease of cardiovascular system (11/24 cases), the respiratory system in pediatrics (15/30 cases) and the disease of urogenital system in Obstetrics & Gynecology (9/27 cases. ) Asphyxial deaths were 7 cases and the death due to adverse drug reaction accounted for 10 cases.

This thesis has studied the magnetic sensing function by using an amorphous magnetic ribbon which has a zero-magnetostrictive composition its magnetic properties through the annealing technique in the demagnetization were measured in the magnetic field. We used a sample of composition (Fe0.06Co0.94)79Si2B19 with a thickness, length and width were 12㎛, 5㎝ and 2.5㎜, As a result of measuring the hysteresis curve of the sample which was examined inducing the pinning site of magnetization filed, the sample which was carried out the two annealing step shows that the LBJ(Large Barkhausen Jump) effect was confirmed at the reversal magnetization field Hw of 0.5 Oe and observed by the variation of the magnetic domain with the process of magnetization. And the sample with was used in this experiment was confirmed to have a magnetic sensing function.
Comparative AFLP Profiles among Strains of Korean Races of Xanthomonas oryzae pv. oryzae.
Kang,Mi-Hyung,Lee,Du-Ku,Noh,Tae-Hwan,Shim,Hyeong-Kwon,Na,Seung-Yong,Kim,Jae-Duk 한국자원식물학회 2004 Plant Resources Vol.7 No.1
We used an amplified fragment length polymorphism (AFLP) analysis, a novel PCR-based technique, to differentiate Xanthomonas oryzae pv. oryzae (Xoo) of Korean races. The 6 strains of Xoo K1, K2, K3 races were tested with 81 AFLP primer combinations to identify the best selective primers. The primer combinations were selected according to their reproducibility, number of polymorphic bands and polymorphism detected among Xoo strains. 18 strains of Xoo K1, K2 and K3 races were analyzed with the selected combinations of primer set. Some primer combinations (Eco R I +1 / Mse I+1) could differentiate Xoo of Korean races that were not distinguished by other fingerprinting analysis. Thus AFLP fingerprinting permitted very fine discrimination among different races.

In this thesis, we fabricate a zero-magnetostrictive amorphous ribbon, measure the impedance effect, and then investigate possibility to be used as a sensor material. Co72.5Fe5.5MoB15Si5 is used as composition of specimen alloy. We first melt the specimen in high frequency induction furnace and then rapidly quench it by using single roll technique. As the result, we obtain a ribbon where length=93㎜, thickness=12㎛ and width=1㎜. Consequently, it is proved through this study that zero-magnetostrictive amorphous ribbon can be used as an excellent magnetic sensor material.
