The information technology should be introduced for firms to cope with the environment and in the introduction of information technology means that the infrastructure or ability for organizational change is established. But whether the firm is successful to the introduction of information technology or not depends on its specific corporate culture. Therefore. the success in the introduction of information technology is prerequisite for a firm to success in the organizational change, and there are corelationships among these three factors. The result of empirical test and the implication of managerial aspects are as follows, In case of the relationships between the type of corporate culture and the introduction of information technology, If we classify the corporate culture as 4 types (development, group, rational, hierarchical culture), control-oriented culture has a negative impact on the success, In the case of the relationship between the type of corporate culture and the resistance against organizational change, If we classify as 4 types, control-oriented culture has a positive impact on the resistance. Therefore, in order to improve the success in the introduction of information technology we should change rigid, multi-hierarchical, skyscraper organization to flexible, small-hierarchical, flat organization. The change lessens the degree of resistance and increases the degree of success in the introduction of information technology. As a result, flexibility-oriented culture is critical to the success in introduction of information technology. Korean firms should make an effort to establish the flexibility-oriented corporate culture. We must promote the decentralization, open communications, democratic decision-making and strategic management in the long-run perspectives. Further research regarding this topic will contribute to increase the competitive power of Korean firms by improving the corporate culture.

Arteriovenous fistula of uterus is rarely reported disease. This vascular malformation is very dangerous condition because Dilatation & curettage can cause massive uterine bleeding without accurate diagnosis. The diagnosis is made by angiography, gray scale ultrasonography, color and duplex doppler ultrasonography, computed tomography, and magnetic resonance imaging is helpful. Especially color and duplex doppler ultrasonography is allows convincing detection and diagnosis of arteriovenous fistula. Recently transcatheter uterine artery embolization is treatment of choice. We have experienced a case of arteriovenous fistula of uterus. Which is presented with a brief review of literature.
마그네트론 스퍼터링 증착 조건에 따른 $\textrm{SnO}_2$ 박막의 미세구조와 가스검지특성 변화

마그네트론 스퍼터로 알루미나 기판위에 $\textrm{SnO}_2$박막을 증착하여 증착온도, rf 전력, 공정기체 중 산소분율(O$_2$/Ar)등 공정변수에 따른 박막의 미세구조와 가스검지 특성을 조사하였다. 증착된 박막의 미세구조는 결정성이 없는 비정질 구조(A), 비정질 기지 중에 결정이 분산된 구조(A=P), 방향성이 거의 없는 다결정 구조(P), 미세 기둥구조(FC), 조대한 기둥구조(CC), 고밀도 특성을 보이는 섬유상 구조(Zone T)의 6가지로 분류되었다. 공정 중 산소를 첨가하지 않았을 때, 저온, 낮은 rf 전력에서 A 구조가, 저온, 높은 rf 전력에서 A+P 구조가, 고온, 높은 rf 전력에서 P 구조가 형성되었고, 산소 첨가 시는 낮은 rf 전력, 저온에서 FC 구조가, 낮은 rf 전력, 고온에서 CC 구조, 높은 rf 전력, 저온에서 Zone T 구조가 형성되었다. 위의 미세구조를 가진 박막들을 센서로 제작하여 $200^{\circ}C$, $300^{\circ}C$, $400^{\circ}C$에서 CO 가스에 대한 민감도를 측정한 결과$200^{\circ}C$에서는 감도가 나타나지 않으며, $300^{\circ}C$, $400^{\circ}C$에서는 FC 구조를 가진 센서가 다른 미세구조를 가진 센서에 비해 우수한 감도를 나타냈다. 이는 미세한 column 들로 이루어진 FC 구조의 높은 비표면적으로 인해 산소와 피검가스의 흡착이 많아지게 되고, 가스흡착에 의한 저항변화, 즉 감도가 높게 나타나는 것으로 판단된다. Microstructures and the gas-sensing characteristics of the $\textrm{SnO}_2$ thin films were studied, which were deposited at various conditions (rf power, sample temperature, $\textrm{O}_2$/Ar ratio) by the rf magnetron sputtering. As a result, six typical microstructures were derived, such as amorphous(A), amorphous mixed with polycrystalline grains (A+P), polycrystalline with random crystalographic orientation (P), fine columnar (FC), coarse columnar (CC) and Zone T (T) with dense fiberous structure. Typically, A, A+ P, and P structures were formed when no $\textrm{O}_2$ was added to the sputter gas, whereas FC, CC, and T structures were obtained when $\textrm{O}_2$ was added. The A structure formed at low rf power and low temperature, the A+P at high rf power and low temperature, and the P at high rf power and high temperature. The FC structure was obtained at low rf power and low temperature. the CC at low rf power and high temperature, and the T at high rf power and low temperature. Results of the gas-sensing test of the sensor chips fabricated from the typical films indicated that the fine columnar microstructure shows the highest sensitivity both at $300^{\circ}C$ and $400^{\circ}C$. It was proposed that this is due to the high specific surface area of the micro-columns.
겨울철 飼育形態가 HOLSTEIN 育成牛의 飼料 攝取, 增體率 및 經濟性에 미치는 影響

This experiment was carried out to investigate the effects of the housing system on the weight gain and economical profit of the growing Hostein heifers. Twenty-four heads of heifer were assigned to the three different kinds of housing systems(enclosed barn, open front loose barn and topless feedlot) for 51 days during the winter time. The results are as follows: 1.Dry matter intake of heifers was 5.63kg in the enclosed barn, 6.2kg in the open-front loose barn and 6.146kg in the topless feedlot. 2.The body weight gain was the highest in the group of the enclosed barn followed by topless feedlot and open-front loose barn(P<0.01) 3.Feed conversion was the hightest when heifers kept in the enclosed barn, intermediate in the topless feedlot and worst in the open-front loose barn. 4.It was also noted that the feed cost per 1kg of body weight gain was the least in the enclosed barn, intermediate in the topless feedlot and the highest in the open-front loose barn. In conclusion, the most favorable result was obtained when heifers kept in the enclosed barn system, followed by topless feedlot and loose barn.
