Deal-or-No-Deal game is a famous TV show program of NBC, USA, which is composed of 10 stages at most. At each stage from the first and the ninth, a banker suggests a deal price to participants. In this paper, we intend to reveal the banker's deal price model using a constrained linear model and quadratic program. As results, we provide a linear model in relation to the deal price at each stage and then show using simulation data that the deal price is equal to the nearest integer of the value to be obtained by the provided linear model.

최근 소프트웨어는 네트워크를 이용한 서비스가 대부분이다. 그 중 그리드 딜리버리는 서버/클라이언트 모델에서 서버의 부담을 줄이기 위해 개발된 서비스다. 그리드 딜리버리는 사용자의 자원을 이용해 서비스를 원활하게 제공하는 방법으로 충분히 악용할 수 있다. 그러므로 이 논문은 악용되고 있는 그리드 딜리버리를 탐색하는 방법을 제안한다. 제안하는 방법은 모니터링 도구를 통해 모든 프로세스의 네트워크 자원을 감시한다. 그리고 네트워크가 사용되는 프로세스를 그리드 딜리버리로 추정하는 방법이다. 제안 방법은 두 단계로 나뉘어 진행된다. 처음으로 네트워크 자원을 사용하는 프로세스를 후보로 뽑아낸다. 두 번째로 이전 단계의 후보에 필터링을 적용해 그리드 딜리버리로 의심되는 프로세스를 찾아낸다. 이 논문에서는 제안하는 방법으로 실제 그리드 딜리버리 프로세스가 검출되는 것을 보임으로 제안하는 방법이 유효함을 보인다.

A PVC membrane electrodes based on Fe(II)-dipyridyl-mefenamic acid ternary complex as ion exchanger were prepared using o-nitrophenyl octyl ether as a plasticizer. The 2,2'-dipyridyl, 4,4'-dipyridyl and 4,4'-dipyridyl-2,2'-dipyridyl were used as dipyridyl derivative ligand. The electrode dxhibits a fast stable and linear response for $10^{-5}-10^{-3}mol/L$ mefenamate with an anionic slope of -55.98, -49.47, -59.35mV/decade in pH 8.9 borate buffer solution respectively. Potentiometric selectivity measurements revealed negligible interferences from aromatic and aliphatic carboxylic acid salts.

This experiment was conducted to determine the mineral absorption character and develop the optimum composition of nutrient solution for dill(Anethum graveolens L.) in hydroponics. Dill(Anethum graveolens L.) plants were grown in nutrient film technique(NFT) supplied with 1/4, 1/2, and 1 strength of the nutrient solution developed by National Research Station in Japan(HRS). Plants grown in 1/2 strength showed the best growth in plant height, fresh weight, and dry weight compared with those grown in 1/4 or 1 strength. In 1/2 strength solution, pH and EC changed little and proper nutrient contents were observed in the leaves as compared to plant nutrient diagnosis standard. Based on these results, optimum macronutrients were composed by nutrient- water absorption rate(n/w) with 1/2 strength: NO$_2$―N 8.85, NH$_4$―N 0.55, P 2.1, K 6.2, Ca 2.8, and Mg 1.7 me L$^{-1}$ To examine the suitability of the nutrient solution developed(SCU) , dill plants were grown in NFT supplied with two different kinds of solution and concentration. 1/2, 1, 3/2 and 25 of SCU and 1/2S of HRS. Changes of pH and EC were not distinct in 1S, but a significant change of pH was shown in low concentrations-HRS 1/2S and SCU 1/2S. Shoot fresh and dry weight were much higher in the plants grown in SCU IS as compared with HRS 1/2S. There were no significant differences in growth of plants grown in SCU IS, 3/2S, and 25. In addition, nutrient contents in the leaves grown by SCU 1S were in proper levels as compared with plant nutrient diagnosis standard. SCU 1S developed in this experiment was found to be optimum for dill in hydroponics.

This study was conducted to evaluate the insecticidal effects of the Anethum graveolens and the Artemisia vulgaris oils against Sitophilus zeamais and Sitotroga cerealella, respectively, in granary. Insecticidal effects of the A. graveolens oil showed 100 % mortality against S. zeamais for 5 days. In the case of S. cerealella, the A. vulgaris oil showed 100 % mortality for 2 h. These results indicate that the A. graveolens and A. vulgaris oils have potential for development as insecticidal to control S. zeamais and S. cerealella, respectively.

The collagen-liposomes were prepared with hydrogenated phosphatidylcholine and by solvent injection method for maximum protection and stable absorption of collagen into the body. Cholesterol was added to phosphatidylcholine to increase the stability of liposome membrane. The mixture was dissolved in ethanol and propylene glycol and PBS Buffer was used to Stabilize ions. The properties collagen-liposome were analyzed by DLS, SEM and POM.

The qualitative and quantitative analyses of phospholipids in chloroform-methanol extracted crude and hexane extracted deodorized soybean oils were carried out by High-Performance Liquid Chromatography (HPLC). The phosphorus contents in hexane extracted crude, degummed, refiend, bleached and deodorized soybean oil were 510, 120, 5, 1.4 and 1 ppm, respectively. The chloroform-methanol extracted crude soybean oil had 800 ppm phosphorus. The phospholipids found in crude oil were phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylserine and phosphatidic acid. Only phosphatidylchonine and phosphatidylethanolamine were detected in the deodorized soybean oil. The HPLC method described in this report can separate and detect individual phospholipids in soybean oil at 0.1 ppm level in 30 min.

A simple and rapid method for preparation of standard phosphatidylcholine hydroperoxide (PCOOH) in chemiluminescence-HPLC assay (CL-HPLC) was developed using the rose bengal dependent spectrofluorometric oxidation. The concentration of obtained PCOOH was determined by FOX (ferrous oxidation-xylenol orange) assay and then subjected to a CL-HPLC system.

Changes in lipid components of Gae-bul, Urechis unicinctus, during hot-air drying ($40^{\circ}C$, 7 hrs) were studied. Raw sample contained 1.3% total lipid (TL) which consisted of 35.1% neutral lipid (NL), 18.0% glycolipid (GL) and 46.9% phospholipid (PL), and dried sample contained 5.3% TL which consisted of 51.8% NL, 20.5%GL and 27.7% PL. There were about 40% decrease in PL content and a slight increase in NL content during drying. The NL of raw sample mainly consists of triglyceride (TG, 39.8%), free sterol (FS, 39.6%), free fatty acid (FFA, 12.2%). and also identified diglyceride (DG), monoglyceride and esterified sterol and hydrocarbon in less quantify. The percent of TG and FS decreased, while that of FFA and DG increased during drying. And main components in the PL were phosphatidyl choline (PC,45.6%), phosphatidyl ethanolamine (PE,34.8%), and followed by phosphatidyl serine (PS) and an unknown substance. In the components of PL, PE, PS and PC decreased slightly in order during drying. And major fatty acids of raw and dried samples were generally 16:0, 18: 1, 18:3, and 20:5. The content of the polyenoic acid such as 20:5 decreased. while the saturated acid increased slightly during drying.
