Costal fisheries use small boat. The boats are frequently substituted with newly made boat or proper boat. When the boat which is substituted with another one after the fixed date for compensation is estimated for fisheries loss by public project, it is matter that which boat is the object for estimating average catch of fish. There are three ways in practical business. They are based on the date of spot probe, the date of conference for compensation and fixed date for compensation. In case of applying the first and the second ways, as the object of compensation is not fixed, there is problem that estimated result can be changed depending on changing boat tons even after the date of spot probe and the fixed date for compensation. Most of all, these ways are against Attached Form No.4 of the Enforcement Ordinance of Fisheries Law which regulate to calculate average catch of fish applying result of fishery for retroactively counted 3 years from the year before the year in which administrative measure day is. The other side, in applying boat tons based on the fixed date for compensation, estimated result of compensation will not change even boat substituted after the fixed date for compensation. Even though applying tons based on the fixed date for compensation, a problem still remains. If the boat get bigger after the fixed date for compensation, the then boat size must be applied for calculating average catch. But the boat get smaller, the changed boat size must be applied. Because changed small boat would be damaged less than the previous boat. And decrease in catch by changing boat into small one is not due to the project but due to the personal responsibility. This will help to increase objectivity and reliance on the compensation result. As the other objects are fixed based on the fixed date for compensation in the Act on Acquisition and Compensation of Land and Others for Public Project, it can be balanced with other object.

Due-date is an important factor in Flexible Manufacturing System scheduling. Even though most of researchers have focused part selection and loading problem using fixed due-date assignment rules, FMSs consist of multi-function machines which facilitate alternative processes. This research investigates interactions of three dispatching mechanisms, three NSS (Next Station Selection) rules and four due-date assignment rules using simulation. Both cost-based and time-based performance measures are considered in this research.

In the previous research, we considered a logistics brokerage problem with the objective of minimizing total transportation lead time of freights in a logistics e-marketplace, in which a logistics brokerage agent intermediates empty vehicles and freights registered by car owners and shippers [7]. However, in the logistics e-marketplace, transportation due date tardiness is more important than the transportation lead time, since transportation service level is critically determined by whether the due date is met or not. Therefore, in this paper, we deal with the logistics brokerage problem with the objective of minimizing total tardiness of freights. Hungarian method based matching algorithms, real time matching(RTM), periodic matching(PM), and fixed matching(FM), are used for solving the problem considered in this paper. In order to test performance of the proposed algorithms, we perform computational experiments on a various problem instances. The results show that the waiting-and-matching algorithms, PM and FM, also give better performance than real time matching strategy, RTM, for the total tardiness minimization problem as the algorithms did for the total lead time minimization problem.

In this paper, scheduling problem is dealt for the minimization of due date penalty for the customer order. Multiproduct batch processes have been dealt with for their suitability for high value added low volume products. Their scheduling problems take minimization of process operation for objective function, which is not enough to meet the customer satisfaction and the process efficiency simultaneously because of increasing requirement of fast adaptation for rapid changing market condition. So new target function has been suggested by other researches to meet two goals. Penalty function minimization is one of them. To present more precisely production scheduling, we develop new scheduling model with penalty function of earliness and tardiness We can find many real cases that penalty parameters are divergent by the difference between the completion time of operation and due date. That is to say, the penalty parameter values for the product change by the customer demand condition. If the order charges different value for due date, we can solve it with the due date period. The period means the time scope where penalty parameter value is 0. If we make use of the due date period, the optimal sequence of our model is not always same with that of fixed due date point. And if every product have due date period, due date of them are overlapped which needs optimization for the maximum profit and minimum penalty. Due date period extension can be enlarged to makespan minimization if every product has the same abundant due date period and same penalty parameter. We solve this new scheduling model by simulated annealing method. We also develop the program, which can calculate the optimal sequence and display the Gantt chart showing the unit progress and time allocation only with processing data.

Wheat flour can be categorized into bread, all-purpose, cake flour according to its protein content. Since optimal wheat flour protein content is different for each end use, it is necessary to diversify the nitrogen fertilizer methods depending on the end use and cultivar. Optimal wheat flour protein content of soft wheat (for cake flour) is lowest (<=10%) among all end use, it is necessary to develop nitrogen fertilizer methods for high yield and low protein content. In order to analyze the yield and quality changes of soft wheat as nitrogen fertilizer amount and splitting timing, soft wheat cultivar 'goso' was sown on paddy soil in jeunju, Republic of Korea ('21.10). the amount of nitrogen fertilizer was divided into 4 levels by adjusting 2kg/10a increments from 5.1 to ll.lkg/lOa, and in the N 7.1 and 9.1 kg/1 Oa(standard) treatment, N amount divided into sowing date:regrowing stage=3:7,4:6(standard), 5:5. In regrowing stage, Tiller number and N fertilizer amount at sowing date showed a correlation; y=-121.14x²+792.66x-525.41 (R²=0.77^*, y: Tiller number/m², x: N amount at sowing date(kg/10a)). Tiller number in regrowing stage was the highest when the nitrogen fertilizer amount at sowing date was 3.23kg/10a. spike number per m² was the highest when N fertilizer was divided into sowing date:regrowing stage=3:7(N amount: 9.1kg/10a). If N fertilizer amount was fixed, grain yield was also the highest when N fertilizer was divided into sowing date :regrowing stage=3:7. Also, N amount at sowing date and grain yield showed no correlation, but N amount at regrowing stage and grain yield showed significant correlation. As N amount increased, protein content also showed a tendency to increase.

Objectives : The OunyukgiUihakbogam authored by Cho, Wonhee, despite its relevance to application of the five circuit theory today, has been under-researched. Methods : Contents on the unique treatment approach through the 'visiting circuit and visiting qi(客運客氣)' of the date of conception was studied. Results & Conclusions : The theory of calculating the date of conception with the date of birth applies the theory of the various combinations of the ten heavenly stems. The gestation period for those born on the day of the rabbit and chicken are either 246 or 306 days, while for those born on the day of the tiger and monkey, 256 days. For those born on the day of the cow or the lamb, 266; for those born on the day of the rat or horse, 276; for those born on the day of the snake or the pig, 286; for those born on the day of the dragon or the dog, 296 days. Once the date of conception is fixed, the visiting circuit and qi is estimated, and a matching formula is chosen and applied.

Under CISG the places of delivery by the seller of the goods are: If the seller is not bound to deliver the goods at any other particular place and the contract of sale involves carriage of the goods, the seller has to hand the goods over to the first carrier for transmission to the buyer. However, if the contract does not involve carriage of the goods, he has to place them at the buyer's disposal at the place where, at the time of the conclusion of the contract, both the seller and the buyer knew that the goods were at, or were to be manufactured or produced. This rule applies when the contract relates to specific goods, or unidentified goods to be drawn from a specific stock or to be manufactured or produced. Finally, in ant other cases the seller has to place the goods at the buyer's disposal at the place where the seller had his place of business at the time of the conclusion of the contract. As to time of delivery, if a date is fixed by or determinable from the contract, the seller has to deliver the goods on that date. If a period for delivery is fixed by or determinable from the contract, he has to deliver the goods on any date within that period. In this way the seller chooses the specific date of delivery within that period, while circumstances indicate otherwise that the choice is to be made by the buyer. There no such date or period, the seller has to deliver the goods within a reasonable time after the conclusion of the contract. If the seller delivers the goods before such the date or period, the buyer is entitled to take delivery or refuse to take delivery. Under these backgrounds of provisions of CISG, this study first suggests the concepts of the handing over of the goods by the seller to the carrier and the placing them at the buyer's disposal. Then it goes further to looks into exactly where and when the delivery has to occur. In these context, this study more examines what happens if there is a breach of contract by the seller in connection with the delivery. That is, if the seller delivers non-conforming goods or at wrong place; what if there is a partial delivery or a premature delivery.

According to the Housing Lease Protection Act, even though it is not registered, if the lessee has completed delivery of a house and the resident registration, the lease shall take effect against the third person from the following day thereof. Any lessee who has met the requirements for opposing power and obtained the fixed date on the lease contract document, shall be entitled to receive the repayment of the deposit from the converted price of the leased house, in preference to any junior obligors and other creditors, at the time of an auction as provided by the Civil Execution Act and a public sale as prescribed by the National Tax Collection Act. The lessee shall be entitled to receive a repayment of a specified amount of the deposit in preference to other persons having the security rights in the leased house. However those provisions give rise to many problems because the Housing Lease Protection Act allows the opposing power and the right of preferential payment from the following date of fulfillment of the requirement. For the purpose of solving the problems, this study suggests that the Housing Lease Protection Act need to be amended as follows. The fixed date should be added to the requirement of opposing power and the preferential right of specified deposit repayment. In addition, the commencement of opposing power and preferential right of deposit repayment need to be taken effect from the day that the requirement is fulfilled.

Various changes in ocular position are possible during general anesthesia as opposed to the awakening state. However, unexpected ocular deviation under general anesthesia is a disconcerting event as it can lead to difficult complications intraoperatively. To date, sudden fixed upward ocular deviation has been rarely reported previously. This phenomenon was observed in an 8-year-old boy during strabismus surgery. Suddenly fixed upward ocular deviation occurred when the speculum was inserted into the right eye. When the eyeball was pulled down, using forceps, there was some resistance, such as contracture of superior rectus. The eyeball sprang back into the upward position when the forceps was released. These changes could hamper the good exposition of the surgical field, leading to significant intraoperative difficulties and complications. Surgeons should be aware of this possibility, despite general anesthesia; if it occurs, proceed with the surgery as planned preoperatively, and both ophthalmic and anesthetic interventions should be used to solve this problem.

In logistics e-marketplaces, brokerage agents intermediate empty vehicles and freights registered by car owners and shippers. In the previous research, we proposed constant periodic/fixed matching algorithms for the logistics brokerage agents with the objective of minimizing the total transportation lead time and the transportation due date tardiness of freights(Jeong, 2004; Jeong, 2007). However, the constant type algorithms cannot consider changes in the balance status of an e-marketplace, i.e. the difference between the numbers of freights and vehicles to wait for matching, because they use non-changing matching periods and amounts. In this paper, we propose variable type algorithms for the logistics brokerage agent, in which the matching periods and amounts are changed continuously by considering the balance status between the freights and vehicles. In order to compare performance of the variable type algorithms to the previous constant type algorithms, we carried out computational experiments on various problem instances. The results show that the variable type algorithms give better performance than the constant type algorithms. We can expect that the logistics brokerage agents can improve their performance by using the proposed variable periodic/fixed matching algorithms.
