This work was conducted to investigate the effect of dietary phytase on growth performance and excreta excretion of growing-finishing pigs for 7 days. Eighty three crossbreeds (Yorkshire ${\times}$ Landrace ${\times}$ Duroc) of growing-finishing pigs were used in this work, and divided into 6 treatments. Six treatments were compared in a $2{\times}2$ factorial arrangement with 2 groups (5 replications/group, 8 head/replications) with the additive phytase and 3 groups(growing I, II and finishing phase) with growing phases. Initial weights with growing phases were $58.6{\pm}3.9$. $83.2{\pm}3.8$ and $111.4{\pm}5.4kg$, respectively. Body weight gain was high in phytase treatment (P<0.01) and low at finishing phase. Feed conversion ratio was high in no phytase treatment and at finishing phase (P<0.05). Feed and water intakes have no significant difference with phytase existence and growing phases. Feces excretion decreased with growing phase (P<0.05), and was low at phytase treatment (P<0.05). There was no significant difference on urine excretion (P>0.05). Nitrogen (N) and phosphorus (P) intake was not found significant difference with phytase and growing phases. N excretion had no significant difference on phytase existence and growing phase (P>0.05), but P excretion decreased at phytase treatment (P<0.05). N and P excretion ratio was low at phytase treatment (P<0.05). Finally, dietary phytase resulted in improvement of growth performance and reduction of excreta excretion of growing-finishing pigs.

Corundum single crystals were grown by the Czochralski technique. Relationships between crystal quality and crystal growth factors such as pulling rate, rotation rate and temperature of the melt were investigated. Optimum pulling and rotation rate for high quality corundum single crystal growth were 4.0mm/hr, 30rpm respectively. Pore was a main defect in corundum crystal and also discussed how to remove this defect by melt temperature control. Growth direction of as grown crystals was identified with(0001). And this direction had largest growth rate. Room temperature absorption spectra were measured and discussed for Cr3+ion doped and non-doped corundum crystals.

김해시에는 약 3,000개가 넘는 기계산업을 중심으로한 전국 두 번째로 많은 중소기업이 있다. 김해국제공항이 10km 이내에 있으며, 부산항과 마산항, 가덕신항만이 자동차로 30분 거리에 있고 서울, 대구, 광주로 가는 고속도로와 울산, 양산, 부산, 창원, 진주를 잇는 동남 공업벨트의 중심지로서 사통팔달의 최적 교통조건을 갖추고 있다. 또 남해바다 해양성기후의 영향을 받아, 화훼, 과수, 채소 등의 신선농산물 재배에도 최적이며 공항을 통해서 50분 거리의 후꾸오까와, 70분 거리에 있는 동경에 이들 농산물의 신속한 수출도 용이하다. 한편 김해시는 가락국의 가야문화권 중심도시로 국립김해박물과의 개관, 문화유적의 복원 등으로 관광도시의 면모도 갖추어 가고 있다. 김해시는 이러한 입지적 요건을 최대한 활용하여 다음과 같은 지역전략산업을 육성하여야 할 것이다. 첫째, 기존의 기계 자동차 금속산업은 지식집약형 기계산업(정밀의료기기 및 첨단 자동차부품포함)으로 특화하여야 할 것이다. 둘째, 화훼 및 농산물수출은 현대화된 재배시설 및 유통시설의 조성, 수출전문생산단지 조성, 대체에너지의 개발 등으로 수출경쟁력을 제고시켜야 할 것이다. 셋째, 기존 기계산업을 정보기술산업과 접목시키는 벤처기업의 육성으로 장기적으로는 하청구조의 산업구조톨 지양하고 기술개발을 통해 경쟁력있는 중소기업을 육성시켜야 할 것이다. 넷째, 유적, 화훼 등의 관광자원을 개발하여 부산과 제주도를 잇는 관광도시로 육성시켜야 할 것이다. 끝으로 인제대학의 특성화분야인 의생명공학을 중심으로 우리나라 최초의 헬씨어밸리(healthier valley)조성올 통해 생물 건강소재산업을 개발하는 것이 바람직 할 것이다. 이상의 특화산업들이 산업연관 효과를 가지고 조화있는 발전을 할 때 21세기의 경쟁력 있는 김해시 건설이 가능할 것이다.
