  • Nicotine is one of the major components of cigarette smoking which causes various systemic and local diseases to human body. The purpose of the present study was to investigate the effects of nicotine on bone mineralization in human fetal osteoblasts cell line(hFOB1). To compare the alkaline ph-osphatase(ALP) synthesis, hFOBl were cultured with DMEM/F-12 1:1 Mixture and 100 pg/ml, 1 ng/ml, 10 ng/ml, 100 ng/ml, 1 ${\mu}g$/ml, 10 ${\mu}g$/ml, 100 ${\mu}g$/ml of nicotine. And to compare the calcium accumulation, hFOB1 cultured for 23 days were quantified and photographed. ALP activity of hFOB1 exposed to nicotine was not significantly changed at a lower concentrations of nicotine, but was significantly decreased at a higher concentrations (10 ${\mu}g$/ml, 100 ${\mu}g$/ml) of nicotine (p<0.05). A quantified calcium acculation in hFOB1 was significantly decreased at 1,10, and 100${\mu}g$/ml of nicotine (p<0.05). Significantly decreased calcium deposition was observed at 1, 10, and 100${\mu}$/ml of nicotine. These results indicate that a higher concentration of nicotine show a negative effects on mineralization of hFOB1.

  • The Incoterms which is one of the most useful international instrument for sale of goods provides when a contract goods deliver, risk passes and how costs are allocated between seller and buyer on the contract as long as they agree to use a rule of the Incoterms rules. The Incoterms rules have come into effective to use for an international or domestic trade of goods since January 2011, which have been modified several times since these established by ICC in 1936. The origin of Incoterms rules may had been appeared from English traditional FOB terms that had been affected to American regulations for the sale of goods. The Incoterms rules which had been started from the traditional English FOB terms and American FOB terms have been expanded other trade terms, such as CIF. Although FOB is based on the COD(Cash on Delivery), it is possible replaced COD to CAD(Cash against Delivery) through the use of Bill of Lading and Letter of Credit in the international sale of goods between seller and buyer according to the development of infrastructures on the international commercial transactions. This article exercises the process of transition of the Incoterms rules, being based on the English and American traditional FOB contract form through review literatures, judical precedents and provisions. Then this article provides some feasible alternatives to attempting to resolve some regulation problems of FCA, CPT, CIP, and D-rules in the Incoterms$^{(R)}$ 2010.

  • Because many of the FOB key, anti-collision algorithm for a seamless multi-access is applied to the smart-key system. In this paper, we have designed and implemented improved anti-collision algorithm that dramatically reduces the communication response time required in the user authentication process immediately after by dynamically changing the order in which the request of the user ID as the user ID on immediately before in the smart key system for vehicles that use many of the FOB key. In order to evaluate the performance of the system the improved anti-collision algorithm is applied, we show the behavior of the algorithm implemented in the state actually mounted on the vehicle and verify that communication response time required for many of the FOB key was reduced by about 33% compared to existing algorithms.

  • The nutraceutical role of fermented omija (Schizandra chinensis) beverage (FOB) was determined through the analysis of fibrinolytic and alcohol metabolizing activities, nitrite scavenging activity, and angiotensin converting enzyme and $\alpha$-glucosidase inhibitory effects. Firstly, FOB increased fibrinolytic activity in a dose-dependent manner and indicated angiotensin converting enzyme inhibitory activity of 94.8% at 20% FOB (0.6 mg/mL). In addition, the inhibitory activities of FOB on $\alpha$-amylase and $\alpha$-glucosidase were determined to be 100% at 100% FOB (3 mg/mL) and 49% at 60% FOB (1.8 mg/mL), respectively. Nitrite scavenging activity of FOB was about 96.1%, 72.3%, and 68.3% on pH 1.2, 3.0, and 6.0 at 100% FOB, respectively. To determine influence of FOB on alcohol metabolism, the generating activities of reduced-nicotinamide adenine dinucleotide (NADH) by alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) were measured. Facilitating rate of ADH activity was 70.3% at 50% FOB, but ALDH activity was not affected. These results revealed that FOB has a strong alcohol metabolizing activity, and fibrinolytic and nitrite scavenging activities and exhibits the angiotensin converting enzyme, $\alpha$-amylase, and $\alpha$-glucosidase inhibitory activities.

  • This study investigated the effects of pretreatment and storage conditions on the properties of stored chestnuts. Effects on chestnuts of refrigerated storage (RNT) and frozen storage (FNT) with no pretreatment, frozen storage after oxalic acid treatment without blanching (FON) and with blanching (FOB) were examined. Water binding capacity, swelling power, solubility, and viscosity of the starch produced from RNT, FNT, and FON were similar to those of the starch produced from control (CON). FOB showed significant differences in these properties from CON. Textural properties of starch gels prepared from stored chestnuts except FOB also were very similar to those of CON starch gels. The sensory characteristics of steamed FON and FNT were similar to those of steamed CON except in brown color and hardness. Steamed FNT tended to have higher brown color and lower hardness than steamed FON. Steamed RNT showed significant differences in all the sensory properties except in hardness and cooked chestnut flavor. Steamed FOB was significantly higher than steamed CON in water release and off-flavor. Among the storage conditions examined, frozen storage with oxalic acid treatment is recommended for the long-term storage of chestnuts.

  • The Rotterdam Rules are not phrased in favour of FOB seller's legal status. Whether it will be wise under the Rotterdam Rules to trade on the basis of cash against M/R largely depends on the interpretation of various provisions of the Rotterdam Rules. To protect his interests the M/R holder and his assigns must have a right of delivery of the cargo at the port of destination. The M/R holder and his assigns must be entitled to the bill of lading or at least be able to prevent the carrier from issuing the bill of lading to the shipper. Besides, any additional right of instruction on the part of the shipper must be blocked. Article 35 of the Rules entitles only the shipper to the bill of lading while 47 entitles only the holder of the bill of lading to delivery. When no bill of lading has been issued Article 45 grants to the shipper a right of instruction whereby the shipper is allowed to advise the carrier as to the name and the address of the consignee. I have suggested that by lack of a specific provision to the contrary the Rotterdam Rules have to be considered to be embedded in the system of law as a whole. From the Common Law it follows that a M/R holder, as owner of the cargo, can ask for delivery of the cargo. As owner of the cargo a M/R holder can also claim the bill of lading, if he does so in time, because it must be implied in the contract of carriage that the carrier must deliver the bill of lading to the owner of the goods. It is for the same reason that a M/R holder can prevent the carrier from issuing the bill of lading to any third party but the M/R holder and from taking instructions from the shipper as to name and address of a consignee other than the M/R holder.

  • Osteoblasts from alveolar bone may have an important role in the bone regeneration for periodontium, but their culture and characterization are not determined yet. The purpose of this study was to investigate the biological characteristics of primary explant cultured osteoblasts(PECO) from alveolar bone. Osteoblasts were isolated and cultured from alveolar socket of extracted tooth in children. To compare the characteristics, osteoblasts and gingival fibroblasts were cultured with DMEM at $37^{\circ}C$, 5% $CO_2$, l00% humidity incubator, and human fetal osteoblasts cell line(hFOB1) were cultured with DMEM at $34^{\circ}C$, 5%, $CO_2$ 100% humidity incubator. To characterize the isolated bone cells, morphologic change, cell proliferation and differentiation were measured. Morphology of PECO was small round body or cuboidal shape on inverted microscope and was similar with hFOB1. PECO became polygonal shape with stellate and had an amorphous shape at 9th passage in culture. PECO had significantly higher activity than that of gingival fibroblasts and hFOB1 in alkaline phosphatase activity. The expression of osteocalcin and bone sialoprotein in PECO was notably increased when compared with hFOB1 and gingival fibroblasts. These result indicated that PECO from alveolar bone in children has an obvious characteristics of osteoblast, maybe applied for the regeneration of bone.

  • Backgrounds: To investigate the role of CT as a screening tool and to compare the diagnostic accuracy with that of the fiberoptic bronchoscopy (FOB) in evaluating the causes of hemoptysis. Methods: The retrospective review of plain chest radiograph, CT and FOB was done in 72 patients with hemoptysis. The diagnosis were confirmed by histology (n=33), bacterial culture (n=6), cytology (n=3), serology (n=2), skin test (n= 1), clinical response (n=5), and airway disease mainly by HRCT (n=22). Results: The causes of hemoptysis were shown to be lung cancer (n=29), bronchiectasis (n=19), tuberculosis (n=12), aspergilloma (n=5), invasive aspergillosis (n=l), COPD (n=3) and others (n=3). The sensitivity was 100% and 91,7% by CT and FOB respectively. The diagnostic compatibility was 95.8% and 59.7% by CT and FOB respectively. The diagnostic compatibility in cases with central airway disease was 96.3% and 100 % in CT and FOB. In parenchymal disease, CT and FOB showed 91.3 % and 43.5 % of compatibility, respectively. airway disease, CT and FOB showed 100% and 31.8% compatibility, respectively. That is to say, CT has higher sensitivity and diagnostic compatibility than FOB for identifying the causes of hemoptysis, and is more helpful for patients with hemoptysis from parenchymal or airway disease. FOB had the advantage in obtaining histologic, cytologic and bacteriologic diagnosis with biopsy or washing Conclusion: CT should be used as the screening method before performing FOB for patients with hemoptysis who have normal or nonspecific findings or peripheral airway disease in plain chest radiograph.

  • The ideal goal of periodontal therapy is the regeneration of periodontal tissue repair of function. Although is very difficult to attain the goal, recent advances in periodontal wound healing concepts encourage hope reaching it. Recently many efforts are concentrated on the regeneration potential of material used in traditional Korean medicine. Phlomidis Radix has been used for the treatment of blood stasis, bone fracture and osteoporosis in traditional Korean medicine. The purpose of this study is to examine effects of dichloromethane fraction Phlomidis Radix on Bone Formation in Human Fetal Osteoblasts. Human fetal osteoblastic cell line(hFOB1 1.19 ;American Type Culture Collection, Manassas, VA) were used and cells were cultured containing DMEM and dichloromethane fraction Phlomidis Radix(100 ng/ml , 1 ${\mu}$/ml, 10 ${\mu}$/ml) at 34$^{\circ}C$ with 5% $CO_2$ in 100% humidity. MTT was performed to examine the viability of the cell, and alkaline phosphatase activity was analyzed to examine the mineralization. Also bone calcification nodules were evaluated. The cellular activity of hFOB1 was increased in 100 ng/ml, 1 ${\mu}$/ml , 10 ${\mu}$/ml of dichloromethane fraction of Phlomidis Radix and especially significant increation was showed in 100 ng/ml of dichloromethane fraction of Phlomidis Radix at 6days (p <0.05). ALP level of hFOB1 was significantly increased in 100 ng/ml , 1 ${\mu}$/ml, 10 ${\mu}$/ml of dichloromethane fraction of Phlomidis Radix and especially more increation was showed in 10 ${\mu}$/ml of dichloromethane fraction of Phlomidis Radix (p <0,05). Calcification nodules of hFOB1 significantly increased in 10 ${\mu]$/ml of dichloromethane fraction of Phlomidis Radix at 21 days of incubation(p<0.05). The results indicate that dicholoromethane fraction of Phlomidis Radix has excellent effects on mineralization of hFOB1.
