공장의 생산력을 향상하기 위하여, 현재 많은 공장에서는 동시에 TPM & TQM을 진행하고 있다. 이러한 활동을 통하여 제품의 품질을 향상하고, 원가를 절감하고, 납기를 단축하며, 생산의 유연성을 확보한다. 본 논문은 한국의 제조업에 대한 설문조사를 통하여 TPM 및 TQM과 생산 실행 요인 사이의 관계를 분석함으로써, 적극적으로 제조업에서 생산력을 향상하고 촉진할 수 있는 요인을 얻는 것이다.

High strength PM aluminium alloys Al-Zn-Mg-Cu (7075 type) were studied by using commercially available powder blends and the sinter-forging technique for component production. Principal areas of focus include the response to PM processing, micro structural assessment and material properties of Aluminium sinter forged products. Green preforms are successfully sintered to near full density by solid-supersolidus liquid phase sintering. Sinter forging method can produce components with net shape and mechanical characteristics of the material have improved greatly. Properties of this new PM Al-alloy were found to be reproducible in an industrial production environment.

This study was conducted to determine the replacement effect of spray dried plasma protein (SDPP) with dried porcine solubles (DPS) in weaning pigs. An ileal digestibility trial, at first, was conducted to formulate the experimental diets with SDPP or DPS. Six piglets (21-d old and 6.12kg BW) with T -cannula in the terminal ileum were used. In a feeding trial, 180 pigs (21-d old and 5.98kg BW) were alloted in a completely randomized block design. Treatments were T1 (SDPP 5%, DPS 0%), T2 (SDPP 5%, DPS 2.5%), T3 (SDPP 2.5%, DPS 0%), and T4 (SDPP 2.5%, DPS 2.5%) for phase I, and T1 (SDPP 3%, DPS 0%), T2 (SDPP 3%, DPS 1.5%), T3 (SDPP 1.5%, DPS 0%), and T4 (SDPP 1.5%, DPS 1.5%) for phase Ⅱ. Phase Ⅰ(0～1 week) diet was formulated to contain 3,300ME kcal/kg and 1.25% digestible lysine, and phase Ⅱ (2～3 week) diet contained 3,320ME kcal/kg and 1.10% digestible lysine. Chemical pompositions of the protein sources were higher in SDPP than DPS: CP (81.60 vs. 56.01), lysine (5.95 vs. 3.36), and methionine (1.85 vs. 1.22). Apparent ileal digestibilities of arginine, isoleucine, leucine, lysine, methionine, threonine and phenylalanine were higher in DPS than SDPP (p<0.05). The apparent ileal digestibility of essential amino acids (average) was also higher in DPS than SDPP (p<0.05). There were no significant differences (p>0.05) in ADG and ADFI of piglets during phase Ⅰ (0～1 week) and Ⅱ (2～3 week) among treatments. However, during phase Ⅱ, T2 showed better FCR than T1 (p<0.05). During the overall period, there was no significant difference in growth performance among treatments. When DPS was partially replaced for SDPP, the diet cost was significantly reduced (p<0.05) in terms of cost/kg of body weight. In summary, the digestibility of DPS was exellent, and it would be concluded that DPS can be partially replaced in the young pigs' diet containing SDPP in order to reduce diet cost in weaning pigs.

The purpose of this study is to propose guidelines for introducing the Just-In-Time (JIT) production system to enhance the competitiveness of Korean manufacturing companies. This study employed an extensive survey on the use of the JIT production systems

한우 종모우의 고환둘레와 정액성상 그리고 후대희 성장 및 도체성적과의 관계를 구명하기 위하여 4~8세 한우 종무우 92두를 공시하였으며 8,628개의 종모우 정액성상 그리고 종모우 후대 814e의 성장 및 도체성적을 이용하였다. 종모우의 고환둘레는 38.73.73 cm, 1차 정액량, 정자농도 및 총정자수는 각각 5.63mL, 17.9/mL 및 100.34/ejaculation 이었고 2차 정액량, 정자농도, 및 총정자수는 각각 5.32mL, 15.0/

Quality management has been recognized as an important means to secure business competitiveness for management environment changes and competitiveness reinforcement. An effort of an ISO 9001 certification has thought that it is the best way to practice quality management. This paper checks a quality management situation of manufacturing companies that acquired ISO 9001 certification. Then, this paper investigates whether quality management is actual1y contributing to production performance and proposes proper alternatives for an improvement of production performance.

This trial was conducted at two locations to compare forage yield, plant height, disease reaction, lodging and maturity of oat(Avm sativa L.) cultivars introduced from Western Australia in comparison with the control cultivar of oat 'Cayuse" over a period
