The purposes of this study were to a) find out the operational characteristics of the contract-managed highschool foodservice in Seoul, b) investigate the expected level of meal-price and facilities investment cost perceived by contract-managed highschool foodservice managers c) compare the present level and expected level of meal-price and facilities investment cost. From October 12 to November 13 in 2001, the questionnaires were mailed to 249 high schools which was managed by contract foodservice company with respondent rate 40.2%. Data were analyzed using SPSS Win(10.0) for descriptive analysis and one group paired t-test. The results of this study were as follows ; 1. The student enrollment of highschools run by contract-managed foodservice was 1,243 with 72.6% participation rate of school lunch program. The average meal-price was 2,138 won. The average annual period of school foodservice operation was 156.78 days per year. The average contracting period was about 3 years. 2. The average cost concerned in the facilities investment amounts 169,578,180 won at the initial investment and 25,204,092 won at the repairs and maintenance cost in the course of operation. 3. The present level of meal-price and facilities investment cost were respectively 2,136won/meal and 171,157,336.72 won. And expected level of meal-price and amount of facilities investment cost were 2,418.75 won and 121,353,215.19 won. Comparing the present level with the expected level of the meal- price and facilities investment cost, expected level of meal-price was significantly higher than the present level of meal-price(p<.001) and expected level of facilities investment cost was significantly lower than present level of facilities investment cost(p<.001).

The purpose of this study is to suggest policies to improve the price escalation system in a construction contract through a Policy Delphi technique. The Delphi, including two times questionnaires and a group discussion, was conducted by joining 14 experts. Also, the escalation provisions of various countries were examined. Results of the Delphi showed that the minimum fluctuation rate for price escalation was desirable at a level of 3%. To compute the fluctuation rate, calculating the price fluctuation of overall articles was more desirable than using price indices. A bidding date was more reasonable as the initial date of change in price. Losses caused by price change should be shared between contractor and owner; therefore a deduction rate should be introduced in price escalation. Meanwhile, overhead and profit should be adjusted in proportion to the fluctuation rate; but advance payment or the delayed construction amount should be deducted from the adjusted amount.

Since the sub-prime mortgage crisis from the US in 2008, the Korean housing market has plummeted. However, the deposit prices of the Korean local lease contract, Chonsei, had been increasing. This increase of Chonsei prices can be a threat to low-income people, most of whom prefer to live in houses with a Chonsei contract. In the housing and Chonsei market, there are many stakeholders with their own interest, hence, simple thoughts about housing and Chonsei market, such as more house supply, will decrease house price, would not work in a real complex housing market. In this research, we suggests system dynamics conceptual model which consists of causal-loop-diagrams for the Chonsei market as well as the housing market. In conclusion, the Chonsei price has its own homeostasis characteristics and different price behavior with housing price in the short and long term period. We found that unless government does not have a structural causation mind in implementing policies in the real estate market, the government may not attain their intended effectiveness on both markets.

This paper presents a formula that relates the optimal exercise boundaries of American call and put options on futures contract. It is shown that the geometric mean of the optimal exercise boundaries for call and put written on the same futures contract with the same exercise price is equal to the exercise price which is time invariant. The paper also investigates the properties of American calls and puts on futures contract.

Purpose: The revenue sharing contract has been used in various industries and it is expected to coordinate the individual companies' operations in a way to improve the whole supply chain performance. This study evaluates the performance of the revenue sharing contract to find out whether this contract achieves its original goal, the supply chain coordination. Research design, data, and methodology: The profit optimization models are developed to represent two stage supply chain system with a supplier and a buyer. By using the numerical examples of the proposed mathematical models, this study examines whether this supply chain contract coordinates the supply chain system. Results: The numerical examples show that the revenue sharing contract does not make the same supply chain profit as the centralized system does. With the proper combination of the wholesale price discount rate and revenue share ratio, both manufacturer and retailer can obtain increased profits from the revenue sharing contract. Conclusions: The outcomes of the numerical analysis imply that the revenue sharing certainly improves the supply chain performance but it does not fully coordinate the supply chain system. By controlling the wholesale price and revenue share ratio, every supply chain member can be beneficiaries of this supply chain contract.

CISG article 74 establishes the general formula applicable in all cases where an aggrieved party is entitled to recover damages. It provides that damages for breach of contract comprise all losses, including loss of profits, caused by the breach, to the extent that these losses were foreseeable by the breaching party at the time the contract was concluded. An aggrieved party may claim under article 74 even if entitled to claim under article 75 or 76. The latter articles explicitly provide that an aggrieved party may recover additional damages under article 74. Articles 75 and 76 apply only in cases where the contract has been avoided. Article 75 measures damages concretely by reference to the price in a substitute transactions, while article 76 measures damages abstractly by reference to the current market price. Article 76 (1) provides that an aggrieved party may not calculate damages under article 76 if it has concluded a substitute transaction under article 75. If however, an aggrieved party concludes a substitute transaction for less than the contract quantity, both articles 75 and 76 may apply. Pursuant to article 77, damages recoverable under articles 74, 75 or 76 are reduced if it is established that the aggrieved party failed to mitigate losses. The reduction is the amount by which the loss should have been mitigated. Article 78 entitles a party to interest on the price and any other sum that is in arrears.

The business market of architecture has got a system that controls a deposit according to the price function. This system is written on a law of contract about countries. So the main body of construction has to make a reasonable contract. This study is written about a rate of numerical index on controling a deposit. We tried to fine problems and solutions of labor expenses, instrument costs and material costs which is so big and changable on the construction market Labor expenses are expressed according to the rate of construction scale between direct and indirect cost that applies ability of works. Instrument costs are expressed according to an output method of a unit price annually and a weight allowance of local instrument conditions and use frequence. The last material costs expressed according to a local weight allowance make a decision of the material cost index. They applies locally relative index more than absolute one on what uses the price rate of producers and importations. This solutions are not enough to apply to the real market, so it needs to exam and to be on the market after a feasibility study.

Referring to Buyer's obligations, the Buyer must pay the price for the goods and take delivery of them as required by the contract. There are vital importances to the Buyer's Fundamental Breach. The legal effects of a breach of contract do not depend on the nature of the obligation broken, but on the consequences of the breach the detriment to the other party. The obligations mentioned to Article 53 are primary obligations which are to be fulfilled in the normal performance of the contract. They include a number of different acts which could be seen as the subject-matter of different obligations. CISG gives further details for the payment of the price in Articles 54 to 59 and for taking delivery in Article 60. The buyer has to take delivery at the respective place within a reasonable period after this communication since he cannot be required to take delivery immediately. Refusing to take delivery in case of delay not constituting a ground for avoiding the contract makes no sense, since this would lead to even later delivery. For the understanding of Buyer's Fundamental Breach, We need to search the Cases referring to the breach of buyer's main obligations.

In international sales of goods, the buyer must pay the price for the goods as required by the contract and CISG, The buyer's this obligation includes taking such steps and complying with such formalities as may be required under the contract, which includes providing the seller with relevant letter of credit through the issuing bank. Where the parties have not stipulated the time limit within which the credit should be opened, but there is an agreed date or period for shipment, the time limit for the L/C opening should be calculated back from the agreed date of shipment or the first date of shipment, while, in addition, the buyer should open the L/C sufficiently earlier than the shipment date in order for the seller to be able to know the L/C's opening before beginning to ship the goods. The L/C provided the buyer should conform to the contract of sale. Therefore, for example, when an unconfirmed L/C is provided violating the agreement or the L/C opened states that, under a FOB contract, a "freght prepaid" bill of lading shall be presented as a required document of the L/C, the buyer has failed to perform his obligation. If the buyer fails to perform his obligations to provide the letter of credit, the seller may require the buyer to perform that obligation; may fix an additional period of time of reasonable length for performance of the obligation; or, the seller may declare the contract avoided, if the failure amounts to a fundamental breach of contract, or if the buyer does not, within the additional period of time fixed by the seller, perform the obligation; and the seller claim damages. However, when a relevant L/C has been issued for the seller, as a rule, he cannot ask directly for the buyer to pay the price before avail himself of the L/C first.
