The several enzymes reaction which involve the quality change of fresh vegetables, such as chlorophylase, polyphenol oxidase, lypoxygenase, C-S-Iyase, myrosinase and enzymes related lignification were reviewed. Numerous enzyme reaction continuously proceeds to the deterioration of vegetables after harvest due to the respiration and biochemical metabolism reaction, especially in case of physical injuring. It is extremely important to inhibit and to control these enzyme reaction in order to maintain the organoleptic and nutritional quality of fresh vegetables.

외국산 양주의 진위를 판정하는 방법을 수립하기 위하여 GC를 이용해서 71종의 표준양주에 함유되어 있는 ethyl acetate와 3종류의 고급 알코올, 즉n-propanol, iso-butanol,iso amyl alchol의 함량을 측정하고, 각양주의 UV최애흡수파장과 흡광도를 측정하여 외국산 양주의 진위판정 기준으로 이용하였다.이와 같은 기준에 의하여 가짜로 의심되는 3종류의 양주를 분석한 결과 다음과 같은 판정ㅇ 가능하였다. 1종은 저급의 외국산 양주가 고급 외국산 양주고 위조된 것이고, 2종은 국산양주가 외국산 양주로 위조된 것으로 판명되었다. This study attempts to establish the methods to evaluate adulterated foreign liquors, we anlized the content of ethyl acetate, n-propanol, iso-butanol and iso-amyl alcohol in 578 reliable and 3 unreliable foriegn liquors and 14 Korean liquors by gas chromatography. Subsequently, UV absorption maximum wavelengh and optical desity of these liquors were measured. These contents of the 3 unreliable foreign liquors were compared with the contents of the reliable liquors. The results were as follows: 1.The Jack Daniels(Old No.7)of foreign bourbon whisky was adultesated to Cammus(VSOP)of foreign cognac brandy. 2.The Captain Q spirit made in Korea was adultesated to Chivas Regal(12 years) of foreign scotch whisky. 3.The Old of spirit made in Korea was adultesated to Johnnie Walker(Black Label, 12 years) of foreign scotch whisky. Therefore reliability if foreign liquor could be decided by teh content of ethyl acetate and higher alchols the measurment fo UV absorption maximum wavelengh and optical density in liquors.

압저항형 스마트 실리콘 압력 센서를 0.6 ㎛ 이중 폴리 실리콘 이중 금속 CMOS 공정으로 구현하기 위하여 설계하였다. 이 스마트 실리콘 압력 센서는 압저항형 저항기들로 된 휘스톤 브리지를 갖는 다이아프램과 op-amp, A/D 변환기, 및 UART 회로 등의 주변회로 들로 구성되어 있다. 브리지 회로의 출력 전압과 압력에 의한 기계적 응력 사이의 관계를 COSMOS-M 상용프로그램으로 다이아프램의 응력 분포를 모의실험하여, 압저항기의 최적의 위치와 크기에 대한 연구를 하였다. CMOS op-amp 회로는 규정된 출력 특성을 얻기 위하여 크기가 다른 트랜지스터들로 설계하여 HSPICE로 모의실험하여 최적화 시켰다. A/D 변화기 회로는 가능한 칩 면적을 줄이기 위하여 서브 레인징 기법과 신경 MOSFET 구조를 이용하여 설계하였다. UART회로는 VHDL 소스 코드와 셀 라이브러리를 이용하고 Synopsys로 합성하여 설계하였다. 회로의 물리적 레이아우트 설계는 Mentor 틀로 설계하였다. 그러나 온도보상회로와 출력오프셋 문제는 아직 해결하지 못하고 다음에 연구할 예정이다. A piezoresistive smart silicon pressure sensor is designed to implement with 0.6 ㎛ double-polysilicon double-metal CMOS precess. This smart pressure sensor is composed of a diaphragm with piezoresistive resistors' Wheatstone bridge and the peripheral circuitry of op-amp, A/D converter and UART. The relationship between the output voltage of the bridge circuit and the mechanical stress by applied pressure was studied by simulating the stress distribution on the diaphragm with COSMOS-M package program to optimize the size and position of piezoresistors. The CMOS op-amp circuit was designed with different CMOS transistor sizes to obtain the defined op-amp output characteristics and simulated with HSPICE. The A/D converter was designed using neuron MOSFET structure and sub-ranging method to minimize the chip area. The UART circuit was designed by using VHDL source code and cell library and by synthesizing with Synopses and the physical layout of the circuit was designed with Mentor tools. The problems for temperature compensation and the output voltage offset were not yet considered.

Rockfish, Sebastes schlegelii (mean length $14.53{\pm}1.14cm$ and mean weight $38.36{\pm}3.45g$), were exposed for 4 weeks with the different levels of ammonia in the concentrations of 0, 0.1, 0.5, and 1.0 mg/L at 19 and $24^{\circ}C$. The indicators of growth performance such as daily length gain, daily weight gain, condition factor, and hematosomatic index were significantly reduced by the ammonia exposure and high temperature. The ammonia exposure induced a significant decrease in hematological parameters, such as red blood cell (RBC) count, white blood cell (WBC) count, hemoglobin (Hb), and hematocrit (Ht), whose trend was more remarkable at $24^{\circ}C$. Mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were also notably decreased by the ammonia exposure. Blood ammonia concentration was considerably increased by the ammonia concentration exposure. In the serum components, the glucose, glutamic oxalate transaminase (GOT), and glutamic pyruvate transaminase (GPT) were substantially increased by the ammonia exposure, whereas total protein was significantly decreased. But, the calcium and magnesium were not considerably changed.

The purpose of this study was to examine the performance of children with nonverbal learning disabilities (NVLD) on visual and verbal metaphoric materials. Seven NVLD children and 13 typically-developing children (TYP) who matched in age and IQ took part in this study. The children ranged from 6 to 9 years of age. Materials were presented in pictures and in words, which made it possible to determine whether NVLD could demonstrate any differences depending on the stimulus materials. The subjects were asked to choose the two pictures or words that were most similar in meaning.The results of this research show that there was a significant difference between the NVLD group and TYP group. Despite a good verbal IQ, NVLD children experienced difficulty in the comprehension of metaphors in both materials. The most interesting result was that NVLD children indicated significantly poor performance in visual material. There were signigicant differences between the two groups in the comprehension of psychological metaphors in visual material and perceptual metaphors in verbal material. This finding suggests that the comprehension of metaphors in pictures can be used to distinguish younger NVLD children from TYP. Furthermore, pictorial stimulus materials provide few cues for the understanding of metaphors.

Juvenile Paralichthys olivaceus (mean length 17.3 ± 2.2 cm, mean weight 46.5 ± 6.3 g) were exposed for 10 days to tributyltin (TBT) at various concentrations (0, 1, 2, 4 and 8 μg/L). Hematological parameters, such as red blood cell (RBC) count, hematocrit (Ht), and hemoglobin (Hb) concentration, were considerably decreased by high TBT concentrations. In plasma constituents, inorganic components such calcium and magnesium were also significantly altered. Plasma calcium was notably decreased, whereas plasma magnesium was increased. The enzyme components, glutamic oxalate transaminase (GOT) and glutamic pyruvate transaminase (GPT), were significantly decreased by TBT exposure. The present findings suggest that TBT exposure can cause significant alterations in hematological parameters and plasma constituents of flatfish Paralichthys olivaceus.
