Characteristics of major suing Chinese cabbage cultivars in Korea, Norangbom(Nor), Gonaenggiyeurum(Gon), Maereuk (Mae) and Housekumgarak (Hou), and their qualities of Kimchies were investigated. Mean weight of the cabbages was in the range of 1.39∼2.40 kg, and was higher Gon, Mae, Nor, Hou in order. Leaves number was Gon 45, Nor 56, Mae 59 and Hou 56 pieces. Sensory taste of raw Chinese cabbage was best in Nor. Decreasing rate of gumminess and chewiness by salting was the highest in Gon and the lowest in Nor. fermentation of Gon and Nor-Kimchi were faster than Mae and Hou-Kimchi. Amount of gas formation during fermentation was the highest in Mae-Kimchi and lowest in Nor-Kimchi. Decreasing rate of AIS was the fastest in Mae-Kimchi and the latest in Hou-Kimchi. Hardness and gumminess of Kimchi fermented for 21 days were to be ordered Mae-Kimchi, Hou-kimchi, Gon-Kimchi and Nor-Kimchi. Overall acceptability by the sensory test was good in Nor- and Hou-Kimchi.

This paper proposes testable design method of Domino CMOS NOR-NOR Array Logic design method. Previous Domino CMOS PLA method is composed of 2 level NAND-NAND Logic. Because NOR-NOR Logic is realized by a parallel circuit, this method can prevent delay time each level and DNOR-PLA include testable circuit system that DNOR-PLA circuit. DNOR-PLA testable algorithm is realized on Prime (Primos) in Pascal language and DNOR-PLA circuit is simulated by PSPICE.

A novel all-optical NOR gate is proposed and demonstrated for the first time by use of gain saturation in a semiconductor optical amplifier (SOA). It is operated by the nonlinearity of the SOA gain. Hence, to obtain sufficient gain saturation of the SOA, pump signals are amplified by an Er-doped fiber amplifier at the input of the SOA. The operation characteristics of the all-optical NOR gate are successfully measured at 10 Gbit/s.

This paper proposes Domino CMOS NOR-NOR Array Logic design method which has the same as characteristic of CMOS and Domino CMOS in Array Logic like PLA, good operation feature, high desity, easy test generation. This testable design method can detect all of faults in the circuit using simple additional circuit and solve the parasitic capacitance problem by improving the pull-down characteristics. A Test generation algorithm and test procedure using concept of PLA product term and personality matrix are proposed, and it was implemented in PASCAL language. This design method is verified by SPICE and P-SPICE simulation.

This paper presents "The 3-User NOR switching channel based on interference decoding with receiver cooperation" in succession to "Jeju Jong Nang channel code I, II". The Jeju Jong Nang code is considered as one of the earliest human binary coded communication (HBCC) in the world with a definite "1" or "0" binary symbolic analysis of switching circuits. In this paper, we introduce a practical example of interference decoding with receiver cooperation based on the three user Jong Nang NOR switching channel. The proposed system models are the three user Jong Nang (TUJN) NOR logic switching on-off, three-user injective deterministic NOR switching channel and Gaussian interference channel (GIC) with receiver cooperation. Therefore, this model is well matched to Shannon binary symmetric and erasure channel capacity. We show the applications of three-user Gaussian interference decoding to obtain deterministic channels which means each receiver cooperation helps to adjacent others in order to increase degree of freedom. Thus, the optimal sum rate of interference mitigation through adjacent receiver cooperation achieves 7 bits.

We proposed a highly integrated 3-dimensional NOR Flash memory array by using vertical 4-bit SONOS NOR flash memory. This structure has a vertical channel, so it is possible to have a long enough channel without extra cell area. Therefore, we can avoid second-bit effect, short channel effect, and redistribution of injected charges. And the proposed array structure is based on three-dimensional integration. Thus, we can obtain a NOR flash memory having $1.5F^2$/bit cell size.

We have investigated the electrical coupling in a 3D monolithic NOR gate structure using TCAD simulation. The electrical coupling of 3D monolithic NOR gate can be caused by the transistor located in the upper/lower or diagonal transistors. The drain current of the upper layer NMOSFET is the same when the voltage of PgateB is 0 V and 1 V. It has been confirmed that the electrical coupling in the diagonal direction does not affect the device characteristics.

Objective : In order to investigate the effect of Curcumae Longae Rhizoma(CLR) extract on the hepatocellular carcinogenesis and acute liver damage induced by diethylnitrosamine(DENA) and $CCl_4$ in rats. Methods : Experimental groups were subdivided into four; normal group (Nor), acute liver damage and hepatocellular cancer inducing control group (Con), and CLR extract 200mg/kg/day (CAA) or 400mg/kg/day (CAB) administered groups to Con. Thereafter the changes of the body weight, the liver weight and the weight of liver/100g body weight, total cholesterol, HDL cholesterol, triglyceride, the activities of AST, ALT, ALP, LDH, AFP, SOD, catalase were measured. And we observed by optical and electron microscopy. Result : 1. The body weight was decreased in Con compared with Nor for 5 weeks, but increased in Con compared with Nor from 6 week to 9 week. During experimental period of total 9 weeks, CAA and CAB were increased compared with Con. 2. The liver weight was increased significantly (p<0.05) in Con compared with Nor. The weight of liver/100g body weight was increased significantly (p<0.05) in Con compared with Nor and decreased significantly (p<0.05) in CAB compared with Con. 3. The level of total cholesterol was increased in Con and CAA compared with Nor, but there was not statistically significant. The level of triglyceride was decreased in Con compared with Nor. But increased in CAA and CAB compared with Con. The level of HDL-cholesterol was significantly increased (p<0.05) in CAA and CAB compared with Con. 4. The activities of AST, ALT were increased in Con compared with Nor, but decreased in CAA compared with Con, significantly decreased (p<0.05) in CAB compared with Con. 5. The activities of ALP, LDH were increased in Con compared with Nor, but decreased in CAA and CAB compared with Con. 6. The activities of AFP was increased significantly (p<0.05) in Con compared with Nor, but decreased significantly (p<0.05) in CAA and CAB compared with Con. 7. The activities of SOD were increased in Con, CAA and CAB compared with Nor, but decreased in CAA and CAB compared with Con. The activities of Catalase was more increased in CAA and CAB compared than Con. 8. The results of light microscopical observation, a number of hepatocytes were damaged in Con compared with Nor and CAB. 9. According to the electron microscopical observation, irregular nuclear membrane, condensed nucleoplasm was observed in Con, the experimental group was observed in the nucleus of the well-preserved and evenly developed nucleoplasm. Conclusions : These results suggest that administration of CLR extract suppress or retard on the hepatocellular carcinogenesis and acute liver damage induced by DENA and $CCl_4$ in rats.

This paper presents the implementation of comparator which are Fail-Safe with respect to faults caused by any single physical defect likely to occur in NMOS and CMOS integrated circuit. The goal is to use it at the Fail-Safe system. First, a new fault model for PLA(Programmable Logic Array) is presented. This model reflects several physical defects in VLSI circuits. It focuses on designs based on PLA because VLSI chips are far too complex to allow detailed analysis of all the possible physical defects that can occur and of the effects on the operation of the circuit. Second, this paper show that these design, which was implemented with 2 level AND_ORor NOR-NOR circuit, are optimal in term of size. And it also present a formal proof that a comparator implemented as NOR-NOR PLA, based on these design, is self-testing with respect to most single faults in the presented fault model. Finally, it discuss the application of the self-testing comparator as a building block for implementing Fail-Safe Adder.
