Recently there is a used a word-outsourcing-in the corporation circumstance. Continuous recession impelling with IMF permitted restructuring measures downsizing unnecessary organization and offered opportunity to breakup structure of 'High cost and Low efficiency' -inefficient and uneconomic production method- in our corporation. Due to the effect of such circumstance change, the construction industry have already introduced and implemented outsourcing in many parts. For successful outsourcing in the construction industry, a mutually close relations and the cooperation are preceded and JIT system is needed to improve these relations. The study recognizes the importance and proportion that outsourcing is occupyed in the construction industry, and suggests the method to improve the productivity by evaluating the factors and usefulness for JIT system to apply to the construction industry.

Recently, the word 'outsourcing' is used frequently in the corporation circumstance. Continuous recession with IMF caused restructuring measures which made unnecessary organization be downsized, and offered opportunity to breakup structure of $^{\circ}A$EHigh cost and Low efficiency, which is inefficient and uneconomic production method' in our corporation. Due to the effect of such circumstance change, the construction industry have already introduced and implemented outsourcing in many parts. For successful outsourcing in the construction industry, close relation and mutual cooperation should be preceded and JIT system is needed to improve the relation. In this study, the importance and proportion in which outsourcing is occupied in the construction industry are recognized, and the method for improving the productivity is suggested through evaluating the factors and usefulness of JIT system which can be applied to the construction industry.

In this paper, we have shown Dalvik virtual machine implementation to reduce the profiling overhead from the trace of the JIT compiler for the specific method. By running the same Java method on the original Dalvik VM and the modified Dalvik VM, we have achieved around 30% performance improvement with this algorithm. In this paper, to increase the reader's understanding of Android Dalvik virtual machine, we will explain the architecture of Dalvik JIT compiler and we will provide the detailed explanation with source codes for modified parts of Dalvik virtual machine. From the industry perspective, we can expect competitive benefits over the competitors with performance improvement in Android core.

This study is focused on evaluating the computer-integrated just-in-time (CI-JIT) production system of a semi-conductor manufacturing firm in Korea. Approaching the mid-1980s, the emphasis was on low price, low-cost operations, and quality, especially in USA. American companies have shifted output to low-wage countries like the Philippines, Korea, Japan, Malaysia and allied countries that can make quality products at low prices. Korea and other Asian countries forego short-term profits to gain a solid foothold in a product market, recognizing that larger market share leads to lower cost and higher profit in the long run. They bring manufacturers and suppliers together to improve material management and operation management, using project teams that investigate topics, such as Just-In-Time(JIT)manufacturing, among others. The "Kanban" word means "card" in Japanese, and is used to indicate the desired final delivery schedule. The operation for a particular item produced is scheduled for a specific time. The same process is extended to the external suppliers. More recently, the cards are gradually being replaced by electronic procedures that follow the same concept. Its capacity must be capable of handling the various transactions required by the JIT coverage as well as some allowances for expanded applications.

Supply chains for agricultural commodities with their various constraints such as production lead time, seasonal production, and methods of storage are limited in the extent to which techniques like Just-in-Time (JIT) inventory management can be applied. It is beyond the ability of producers to control harvest time and many agricultural products are perishable so that they can incur exceptional losses in storage if they are not handled correctly. This is a source of additional costs and inefficiency in supply chain management. The purpose of this study is to reduce or eliminate such sources of loss and inefficiency and to identify success factors for the JIT inventory management system where it can be applied for agricultural products. Where JIT techniques can be applied in supply chain management for agricultural products, costs such as transportation, inventory, and storage losses can be reduced with concurrent increases in efficiency. In the paper, some of the problems associated with applying JIT inventory control methods in supply chain management for agricultural commodities will be reported through a series of case studies.

This study proposes D- shortage control system which is a convenient tool for cooperative companies to reduce shortages which frequently break out between the manufacturing companies and the cooperative companies. On the ground of theoretical analysis of MRP and JIT system, D- shortage control system sets up a schedule that secures the delivery date by precedent scheduling( D-) comparing with MRP It also syncronizes business, production and release, and builds the pull system comparing with JIT. The factors causing shotages are the scheduling absurdity and the controlling absurdity. The scheduling absurdity can be settled by the calculating required quantity method of MRP and the controlling absurdity can be settled by daily control of business, production and pruchasing fuctions by the pull system of JIT. And the inventory and the WIP can be reduced by the operating of PULL system and by the settlement of D- shortage control practices. The Application of D- shortage control system, therefore, enables the rationalization of logistics and reduces the inventory And it leads to the reinforced competitiveness and the security of subsistence of manufacturer by the cost ruduction, the reduction of financial difficulty, and the insurance of the delivery date.

The study attempted to answer the questions related to the expected effects of supply chain management variables which include: Partnership with Suppliers (PS), Relationships with Customers (RC), Quality of Information Exchange (QIE), and Postponement (P), as independent variables, total quality management (TQM) as a dependents variable, and just in time (JIT) as a mediator variable. The study relies on the descriptive approach by conducting an empirical study on commercial companies in Riyadh Governorate in the Kingdom of Saudi Arabia. Through the methods of descriptive and analytical statistics represented in exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and structural equation modeling (SEM)), using the AMOS and SPSS programs, the results of the applied study indicated that: There is an effect of supply chain management variables (quality of information exchange, Postponement) on just in time (JIT), there is no effect of the supply chain variables (relationship with customers, partnership with suppliers) on just in time (JIT), there is an indirect effect of the quality of information exchange, Postponement, partnership with suppliers, the relationship with customers on total quality management (TQM), relationship with customers affect on total quality management (TQM) indirectly, just in time (JIT) does not affect total quality management (TQM)

본 논문에서, 우리는 일본제조 시스템의 대표격인 도요타 시스템을 소개하려고 한다. 도요타 시스템은 일본식 생산관리라고 하는 즉시시스템(JIT)과 전사적 품질관리(TQC)로 세계 최고의 생산성과 품질을 이룩했다. 도요타에서 JIT시스템을 성공시키기 위한 여섯 가지 기본 사항을 살펴보았다. 또한 JIT 시스템의 운영도구인 간판 시스템을 자세히 살펴봤다. 결론에선 우리나라 생산 시스템에 도요타 생산시스템이 도움이 되며, 우리나라와 일본을 비교하여, 우리도 일본 생산 시스템을 앞설 수 있음을 제시했다.
