It is important to study the activity of drug biotransformation enzymes, because from a pharmacological and therapeutic point of view these enzymes are resposible for eliminating most drugs. Their level is ciritical when deciding the dose regimen. (From a toxicological perspective, the role of these enzymes varies, with some of them being directly responsible for activation of certain chemicals to reactive intermediates with deleterious consequence to the animal.) Experiments were designed to measure in vitro, the activity of drug metabolizing enzymes in liver of Korean native cattle. The microsomal monooxygenase activities were evaluated utilizing specific substrates. The activities of BPDM and TST 6β-hydroxylase were seemed to be high level relatively to other monooxygenzses such as ECOD, EROD and AH. Interestingly, TST 16α-hydroxylase which is a maker enzyme for CYP ⅠLA was not detected in Korean native cattle. These results sugest that Korean native cattle have high contents of CYP IIB1 and CYP IIIA.

The population of Korean Chinese in 1979 was 30,117, among which 94% were from the Shantung peninsula. Compared to the Southeast Asian Chinese, the society of Korean Chinese are a homogeneous ethnic group which uses the same language, came from the same area, and follows the ideology of anti-communism as directed by the Taiwan government. 78% of Korean Chinese are engaged in restaurant businesses, and the others are engaged in general merchandise retailing, Chinese herbal medicine, Chinese herb shops, tearooms, public bath businesses, and tailor shops. In general, job and business opportunities open to Chinese are very limited in Korea. The major organization of Chinese society is " the Chinese Central Association" to which fifth-one local associations belong. Chinese associations play a middleman role between Chinese people and the Chinese embassy in Seoul by reporting people's opinions to the embassy and sending messages from the embassy to the people. Other voluntary organizations are restaurant business associations, local and surname associations, religious and educational associations, and so on which add up to twenty. Most of the voluntary organizations are usually linked to one another through interlocking relations. Thus, leaders in a Chinese community play multiple roles in different associations. Most Chinese children attend Chinese schools which consist of one year of kindergarten, six tears of primary school, and six years of high school. As of 1980, there are nationwide one kindergartens, thirty-nine primary schools, and five high schools. The years of 1882 saw the beginning of Chinese immigration to Korea which was the result of a treaty on trade between Korea and China. Although there were only 209 Chinese in 1883, The Chinese population in Korea reached the level of 82,600 people in 1942. After 1945, however, the division of the country forced two-thirds of the Chinese to live in the northern part of the peninsula. The drop of Chinese immigration after the communalization of mainland China in 1949 also contributed to the decrease of the Chinese population in South Korea along with the government's ban on any immigration into the country. Since then the Chinese population increased only by natural growth, and it reached 32,980 in 1972. In the 1970's, the Chinese population slowly decreased to reach the level of only 29,600 in 1980. The decrease of the Chinese population in the 1970's has been the result of migration of Chinese people to foreign lands. In order to find the trend of their actual mobility, the statistics of Chinese entry-exit have been reviewed. In 1967 the number of entries was 2,600 and the number of was 2,800. Since 1970 it shows a sharp increase and, in 1977, the number of Chinese entering the country was 18,300 and the number leaving the country was 20,00. In other words, the Korean Chinese changed their way of life by traveling back and forth frequently, and some of them even live in Taiwan, visiting Korea once a year only to renew residenceship. These people can be categorized as 'mobile population'. The number of reentry for residence in 1979 was 6,638 which is 22% if the Korean Chinese. If we assume that the average Chinese goes overseas and comes back twice a year, it can be estimated that 11% of Koran Chinese belong to the category of 'mobile population'. In addition, the number of visas issued by the Chinese consulate in Seoul, the number of entries and exits of overseas Chinese to Taiwan, and the number of graduates from Taiwan colleges and junior colleges were also analyzed to prove the high mobility of Korean Chinese in the 1970's. Most of the Korean Chinese who moved out of Korean go to Taiwan and to the United States of America. In this paper, only migration to Taiwan has been analyzed. Interviews were conducted during the period of January and February of 1980 with fifty one Koran Chinese who reside in Taiwan. Life in Taiwan for these emigrants was proven not to be that of a comfortable and leisurely nature. Instead, Korean Chinese have found themselves in a category of a 'minority in their fatherland, i.e. the Korean Chinese formed their own small society by getting together by themselves, having certain common stores they shop, and having little chance to make new Taiwanese friends. The reasons are that either they are too busy keeping stores or small restaurants, or they spend most of their time seeing each other. Moreover, those who do not have any jobs usually engage in a kind of 'shuttle trade', which is conducted by traveling between Korea and Taiwan. Traveling between the two countries, Chinese carry items like herbal drugs, jewels made of ivory, coral, and jade, tapestries, toys and so on from Taiwan to Korea, and blankets, bed spreads, clothes, dresses, ginseng products, and others from Korea to Taiwan. This shuttle trade has become possible by the well systematized process including institutions like drug stores, jewelry stores, and gift shops in Taiwan, and many middleman who purchase the carried items. The store managers in Taiwan take all the carried items from Korea, as well as supplying items to be carried to Korea. Most Chinese migrate to Taiwan as individuals rather than as a whole family. Many Chinese families in Korea end up having their members spread out in different countries, becoming a 'multinational family'. Among the fifty one cases studied, thirty (58%) went to Taiwan for study. Among thirty cases, only seven were attending colleges at the time of study, the rest having been settled in Taiwan after gradation or dropping out of school. The tread is likely to continue that Korean Chinese students entering Taiwan colleges will end up setting in Taiwan more or less permanently. Chinese students in Korea are encouraged by teachers and parents to apply to colleges in Taiwan rather than applying to Korean colleges. One of the major reasons is the way they were educated in primary textbooks under a Chinese curriculum, and are taught by Taiwan colleges educated teachers. The Korean governments liberal educational police for foreigners helped to create the above situation. Therefore Chinese students are well exposed to Chinese culture and society before they go to Taiwan. The strong ethnic identity achieved by pure Chinese education surely induced many Chinese students to apply to Taiwan colleges and to settle in Taiwan. Moreover, other policies of the Korean government in the areas such as naturalization and financial aid, are very restrictive toward Chinese. Curiously enough, a seemingly contradictory policy of permissive education and restrictive naturalization and commerce has maintained a strong ethnic among Chinese people. As a result Chinese began to search for an alternative to give their ethnic identity not a weakness but a pride. Since being a Chinese is a weakness in Korea, Chinese people moved out, leaving their Korean hometowns. Korean Chinese society has a basic group identity as H. Isaacs remarked in "Basic Group Identity: The Idols of the Tribe" ( in Ethnicity : Theory and Experience, edited with an introduction by N, Glazer and Daniel P, Moynihan, 1975). "The Chinese group in Korea is not used as a political or economic unit un order to get ethnic interest as Glazer, Mpynihan and Patterson indicated in the same book. Rather Chinese identity became an ideology in that society. As Aronson insisted, Chinese identity in Korea operates as a leading ideology among Chinese people in Korea. Being one of the first exploratory researches on Korean Chinese, this study has taken a general approach. Future research should deal with more specific subjects such as interethnic relationships between Koreans and Chinese, intermarriages between them, assimilation patterns, the different value systems between the first, second, and third generation Chinese and other anthropological issues. And since many Chinese moved to the United States, a follow-up study of Korean Chinese in the U.S. will be an interesting cross-cultural study.

치과주조용 Ag-Pd-Zn-Sn-In 합금의 시효경화 특성

이재호,김명진,이희경,김형일,설효정 大韓齒科器材學會 2004 대한치과재료학회지 Vol.31 No.1

Cu가 첨가되어 있지 않고, 대신에 상대적으로 많은 양의 Zn 그리고 소량의 Sn과 In이 첨가된 치과주조용 Ag-Pd-Zn-Sn-In 합금의 시효경화 특성을 경도 시험, X선회절 실험, 주사전자현미경 관찰, 전자탐침 미소분석법으로 조사하여, 다음과 같은 결과를 얻었다. 1. 950℃에서 용체화처리된 시편을 500℃와 550℃에서 등온시효처리하면, 시효 초기에 경도가 완만히 상승하여 최고 경도에 도달하였고 최고 경도를 일정 기간 유지하고 나서 서서히 하강하였다. 2. 용체화처리된 시편은 Pd 원자가 고용된 Ag-rich α1상, Pd3Sn인 α2상, Pd2Zn인 α3상의 3상 공존이었고, 등온시효처리함에 따라 Ag-rich α1상에서 Pd-rich 상으로 추정되는 β상이 석출하였다. 3. 시효 초기의 경화는 Ag-rich 기지에서 Pd-rich 상의 석출로 인한 격자변형에 기인하는 것으로 추정된다. 4. 시효처리 시간을 연장함에 따른 과시효 연화는 입계에 Ag-rich α1상과 Pd-rich β상으로 된 층상조직의 석출과 조대화에 기인하였다. 5. Pd3Sn인 α2상과 Pd2Zn인 α3상은 시효경화에 기여하지 않았다. Age-hardening characteristics of a dental casting Ag-Pd-Zn-Sn-In alloy without copper (52.0 wt% Ag - 39.9 wt% Pd - 4.0 wt% Zn - 2.0 wt% Sn - 2.0 wt% In - 0.1 wt% Ir) was investigated by means of hardness test, X-ray diffraction study, scanning electron microscopic observations and electron probe microanalysis. The specimen solution-treated at 950℃ was three phases of the Ag-rich α1 phase containing Pd element, the α2 phase based on Pd3Sn and the α3 phase based on Pd2Zn, and the Pd-rich β phase was precipitated from the Ag-rich α1 phase by the isothermal ageing,. The initial hardening seemed to be attributed to coherency strains which were formed in the Ag-rich matrix by the precipitation of Pd-rich phase. Overageing with softening was due to the formation and coarsening of the lamella precipitates at grain boundaries, which were composed of the Ag-rich α1 and Pd-rich β phases. The α2 phase based on Pd3Sn and the α3 phase based on Pd2Zn did not contribute to the age-hardening of this alloy.

The purpose of this study was to investigate the instrumental and sensorycharacteristics of Noralbyung made from rice flour and glutinous rice flour containing 1, 2, or 3% of ginger powder. The result of sensory evaluation showed that Noralbyung containing 252g rice flour, 45g (15%) glutinous rice flour, 3g (1%) ginger powder, 3g cinnamon powder, 55m1 honey, 15tnl water, and 3g (1%) salt had high overall acceptability and chewiness preference. From textural analysis, springinewnd gumminess were increased by adding ginger powder. The Hunter color a-, L- and b-values of Noralbyung were all decreased by increasing the level of ginger powder. The moisture content (%) was higher in Noralbyung with sugar than honey. With increasing ginger powder content, the moisture content (%) of Noralbyung was decreased. From these test result, the most desirable recipe for Noralbyung was 252g rice flour, 45g (15%) glutinous rice flour, 3g (1%) ginger powder, 3g cinnamon powder, 55m1 honey, 15m1 water, and 3g (1%) salt. The moisture content was 37.72%.

An integrated silicon pressure sensor has been designed, fabricated and tested. The signal conditioning circuits were designed to include calibration and temperature compensation of output voltage through trimming of diffusion and ion-implanted resistors. Before trimming of resistors, the compensation parameters such as pressure sensitivity, temperature coefficient of pressure sensitivity, temperature coefficient of piezoresistors and pressure sensitivity of piezoresistors were measured. Then offset voltage, span, and temperature coefficients of offset voltage and span were calibrated by trimming of resistors. The measured output voltage met our design specification and simulation value above room temperature. But, the measured output voltage at -30°C deviated from our design specification and simulation value because the offset voltages were found to vary randomly as a function of temperature.

The interaction of CO with W(110) surface was investigated through LEED, TDS, and photoelectron spectroscopy using synchrotron radiation under UHV condition. After CO saturation at RT, two desorption states, called α and β , were observed at about 400 and 1150 K in thermal desorption spectra, respectively. The kinetics of 3-CO followed the first order kinetics, indicating the existence of molecular CO on W(110) surface. This is contrary to the previous results. The O 1s BE(binding energy) of CO adsorbed on W(110) surface at room temperature was 529.9 eV. On the other hand, the O 1s BE of β-CO after heating to 900 K was different from that of oxygen adsorbed W(110) surface, suggesting a different adsorption state. According to the UP valence band spectra, we observed two peaks at near -10.7 eV (4σ) and -7.0 eV (5σ+1π), indicating the molecular adsorption of CO at room temperature. Furthermore we could see the 4σ peak at the various photon energy and elevated temperatures. Comparing the energy separation, Δ(4σ-1π) , between 4σ and 1π UP peaks of chemisorbed CO, we found that an increased separation reflects an decreased C-O bond strength. Therefore on the basis of TDS and photoelectron spectroscopy, we could suggest that β state of CO on W(110) may not be dissociated and has an adsorption geometry of lying-down mode.
