In the Donghae bentonite mine area, the alteration minerals such as smectite, clinoptiloite, mordenite, opal CT and feldspar occur in the tertiary tuffaceous rocks. The mineral assemblages of the rocks are grouped into four types : volcanic glass-smectite, clinoptilolite-smecite-opal CT, mordenite-potassium feldspar-smectite, well-crystalline smectite-potassium feldspar. The first two assemblages are found in the bedded tuffaceous sedimentary rocks. The other types are distributed in the rhyolitic rocks of eastern part of this area. Mineralogical properties of the smectites in the each assemblage type were investigated by X-ray diffraction, chemical analysis, DTA and IR. The results show that the all smectite specimens are mainly composed of (Mg, Ca)-montmorillonite. But the well-crystalline smectites show the considerably different data from other smectites in mineralogical properties. Judging from the occurrence and properties, it seems that the well crystalline smerctite can not interpret to be formed only by diagenetic alteration. Perhaps it can be considered that the formation of the smectite was influenced significantly significantly by hydrothermal alteration.

This study was performed to evaluate the prevalence of spinal disorders in dogs, as well as their breed, age, gender and body weight distributions. Seventy cases of caine spinal disoreders presented in the period 2001 and 2006 were reviewed. The diagnosis was obtained by survey radiographs, myelogram, CSF analysis, CT and MRI. The most frequent breed was Maltese(15 cases), and followed by Yorkshire Terrier (10 cases), Pekingese (9 cases). Canine spinal disorders occurred from 7 month to 17 year old dog, mean age was 5.3±3.7 year-old. Canine spinal disorders occurred more often in females(59.7%) than males. Mean body weight was 5.87±7.02 kg. Degenerative (39 cases, 43.3%) and anomalous (24 cases, 26.7%) disorders were dominant in 90 specific disease distribution. This results can be a reference data for the further study.

The smectite-rich clays were found locally in Paleozoic calcareous sedimentary rocks in the Samcheok area. Their occurrences were investigated in detail, and the physico-chemical properties of the clays were also determined by X-ray diffraction, chemical analysis, thermal analysis and cation exchanging experiment. The smectitie clays occur as the fissure filling dyke developed in calcareous semimentary rock and as alteration products of instrusive rhyolite. Most of clays occur at the contact between the sedimentary rock and the rhyolite, and the alteration zone was observed only in rhyolite body close to the contact. Judging from their occurrences, it is believed that the smectite-rich clays in this area were formed by the hydrothemal alteration. The smectite clays from the area are mainly composed of Ca-montmorillinite, and associated with small quantities of quartz, opal-CT and feldspar. The montmorillinites from this area lower in Fe content, and higher in exchangeable Ca ion, compared to those of bentonite from the Yangnam-Yeongil area.

In order to find out and show the maximum amount of water and fat which can be mixed and emulsified with the given meat ingredients, the chemical components and specific properties of the followings are investigated. The chemical content of pork and lard were water 74.3%, 15.2%, protein 21.3%, 6.7% , fat 4.7%, 81.3% and w/p of pork was 3.48, F/P was 0.22. Among the protein, the content of salt soluble proteins of pork was 43.2. The moisture was decreased by the increasing fat level and the fat contents were increased by the increasing of fat level so, by adding fat of 50% level, the fat content of the finished sausages will be less than 30%. But the minimum protein level was 10.5% which is above the 10% that is considered as the minimum level for the acceptable meat emulsion. The lower stability was found in the 20~40% of fat levels in the formulations that consists of higher levels of fat and added water.

경북 양남지역의 제3기층내에 많은 밴토나이트광상이 분포되어있다. 이들 벤토나이트광상은 제3기의 전동층과 어일화산암류의 암층내에 배태되어 있으며 광상의 모암은 주로 안산암질의 화산암 및 화산쇠설성 퇴적암으로 되어있다. 이들 벤토나이트광상의 광체들은 주로 괴상으로 소규모로 나타나는 특징이 있다. 또 본 지역의 벤토나이트광상들은 단층선상이나 그 인접부에 분포하고 있어 광상의 형성과 단층과의 밀접한 관계가 있을 것으로 사료된다. 각 광상에서 산출되는 몬모릴로나이트의 광학적 특성과 그 수반광물이 모든 광물에 있어서 유사하게 나타난다. 몇몇 광산에 있어서 최상부층에 두껍게 피복된 안산암체가 부분적, 불규칙적으로 벤토나이트화 되어 있는 것이 관찰된다. 본 지역 벤토나이트광상의 산출상태를 여러가지 관점에서 검토한 결과 이들 벤토나이트광상은 단순한 숙성벽질작용만으로 형성되었다고 생각하기는 어려운 것 같다. 그래서 본 광상들은 단층과 같은 구조적 약대를 따라 이동된 열수 혹은 지하수등에 의한 모암의 변질효과도 관여하여 형성된 것으로 생각된다. Many bentonite deposit are distributed in the Tertiary rocks of the Yangnam area, Kyeongbod, Korea. These bentonite deposits occur in the Jeondong Formation and the Eoil Volcanics of the Tertiary, age and their origical rocks are mainly of andesitic volbanic rocks and pyroclastic sedimentary rocks. The ventonite deposits occur as massive and small-scale ore. The deposits are located around fault lines in the area. Threrefore, it seems tat the genesis of the bentonite deposits are closely related to the faults. Mineralogical characteristics of montmorillnite and associated minerals in the ventonites are simillar in all deposits. In some bentonite mines, it is observed that the thick andesite bodies occurred in the most upper part of the mines have been altered partially to bentonite. Judging from the occurrences and mineralogy, it is obvious tat the bentonite diposits were not formed by only a simple diagenetic process. Therefore, it is assumed that the deposits were mainly formed from the alteration by hydrothermal solution or ground water moved along the structually weak zone such as fault.

This paper presents a miniaturized electromagnetic wave detector. The dimension is reduced down to 31×18×13.5 ㎣ by using common OP-AMPs for amplification and oscillation. The strength from wave radiators is indicated by a color LED; green, orange and red colors mean the low, the middle and the high level, respectively. An alarm bell rings as the wave strength becomes above high level. The detector uses 3V battery. The detector could be used for a cellular phone decoration, a necklace pendant and a key holder.

Objectives : There are a number of preceding epidemiological studies reporting gender differences in the genetic etiology of alcohol dependence. The author investigated gender difference in the frequencies of ADH2 and ALDH2 genoypes between the patients with alcohol dependence and normal control. Methods : The subjects were 141 alcohol dependent patients (104 males, 37 females) and 138 normal control (79 males, 59 females). The frequencies of 1/1 and 1/2+2/2 (2+ afterward) genotypes for ADH2 and ALDH2 were investigated in male and female between alcohol dependence and normal control group. DNA was extracted from WBC in peripheral venous blood and PCR-RFLP method was used out for genotyping. Results : First, the frequency of ADH2 1/1 genotype was significantly higher in alcohol dependent patients than normal control in both genders. Second, while there was no gender difference in the frequency of ADH2 1/1 genotype in normal controls, in the patient group however, the frequency was significantly higher in females than males. Third, in male subjects with alcohol dependence, the frequency of ALDH2 1/1 genotype was significantly higher than in male normal control subjects. On the other hand, in female subjects with alcohol dependence, the frequency of ALDH2 2+ genotype was significantly higher than in female normal control subjects. Conclusion : These results suggest that while the risk of alcohol dependence is predominantly affected by ALDH2 1/1 geno-type in male, the female ADH2 1/1 genotype is mainly associated with the risk of alcohol dependence. This means that there are gender differences in the genetic etiology of alcohol dependence.
