  • The effect of gelatine on the electrodeposition of copper in cupric sulfate-sulfuric acid solution was investi-gated using an ac impedance technique. In the presence of gelatine, the charge transfer resistance was in-creased and the electrical double layer capacitance was decreased. A model was suggested to explain the im-pedance spectra and it fitted well the experimental data. Also the uniformity of deposit thickness was in-creased while the grain size was decreased by the addition of gelatine.

  • Experimental studies were performed to investigate the injury potential of BB pellets through gelatine based simulants. In order to record BB pellet movements penetrating into the target simulant, a high-speed video camera was used. In this study the first investigation involved the effects on concentrations, homogeneity and gelation times of the gelatine simulant. The second investigation involved the penetration depth of the pellets to the simulant by different distances between the BB gun and the simulant. The final one is associated with impact velocity, threshold velocity and penetration depth of the pellets by different kinetic energies of the BB gun. Results provided the basis in assessing the injury potential of BB pellets.

  • This study evaluated the effect of the addition of pig skin gelatine powder with different levels on the chemical compositions, cooking characteristics, and sensory properties of tteokgalbi. Tteokgalbi was produced from products containing 0% (control), 1%, 2%, 3%, and 4% pig skin gelatine powder. The protein and moisture contents of samples increased with an increase of pig skin gelatin powder levels. In addition, the pH value and CIE $b^*$ values of uncooked and cooked samples increased with increasing amount of pig skin gelatin powder. However, cooking loss, diameter reduction, and thickness reduction of samples decreased with an increase of gelatin powder contents. The hardness, gumminess, and chewiness of samples increased with an increase of gelatin powder contents, and sensory evaluation of tteokgalbi containing 2~3% pig skin gelatin powder was the highest. Therefore, usages of pig skin gelatin powder can improve quality characteristics of tteokgalbi.

Bleeding & Infection Control by the Circumferential Suture & Drainage on Active Bleeding Extraction Socket under Sedation And Local Anesthesia in a Multiple Medically Compromised Patient with Anticoagulation Drug (항응고제 투여중인 다발성 전신질환자에서 과도한 발치창 출혈부의 진정요법과 국소마취 시행하에 창상주위 봉합과 배농술 통한 출혈과 감염조절)

  • There are five principal causes for excessive bleeding in the immediate postextraction phase ; (1) Vascular wall alteration (wound infection, scurvy, chemicals, allergy) (2) Disorders of platelet function (genetic defect, drug-aspirin, autoimmune disease) (3) Thrombocytopenic purpuras (radiation, leukemia), (4) Inherited disorders of coagulation (hemophilia, Christmas disease, vitamin deficiency, anticoagulation drug-heparin, coumarin, aspirin, plavix). If the hemorrhage from postextraction wound is unusually aggressive, and then dehydration and airway problem are occurred, the socket must be packed with gelatine sponge(Gelfoam) that was moistened with thrombin and wound closure & pressure dressing are applied. The thrombin clots fibrinogen to produce rapid hemostasis. Gelatine sponges moistened with thrombin provide effective coagulation of hemorrhage from small veins and capillaries. But, in dental alveoli, gelatine sponges may absorb oral microorganisms and cause alveolar osteitis (infection). This is a case report of bleeding and infection control by the circumferential suture and iodoform gauze drainage on infected active bleeding extraction socket under sedation and local anesthesia in a 71-years-old male patient with anticoagulation drug.

  • The photographic characteristics have been studied in relation with various molecular weights of Polyvinylpyrrolidone(PVP). The shape of silver halogen crystals by physical ripening of mixture of photographic gelatine and various molecular weights of PVP were observed. Then, the photographic characteristics have been studied by chemical ripening. Results were concluded as follows: 1. All of the crystals have formed in the shape of (100) or (111). 2. Photographic characteristics were inferior by using PVP of higher molecular weight. 3. Photographic characteristics were superior by using PVP of lower molecular weight. 4. Photographic characteristic were compared with various Emulsion thickness and Tested Resolving power.

  • The blast-induced ground vibrations is one of the most important factors which is considered to design blasting patterns in urban excavation. To compare with vibration level of different explosives, peak particle velocity of each explosive was measured. The results are summerized as follows. 1. Among the three kinds of explosives, the largest vibration was obtained from the gelatine dynamite, while the smallest was blasting of ammonium nitrate. 2. The vibration levels of ammonium nitrate and slurry explosive were smaller about 35%, 20% respectively than that of gelatine dynamite.

  • The polarographic behaviors of Tl(I) was investigated in EDTA and NTA as supporting electrolytes for determination of Tl(I). A base solution containing 0.005 % gelatine, 0.1 M EDTA, and 0.05 M NTA was used. The halfwave potential of Tl(I) determined is -0.495 V v.s. S.C.E. in 0.1 M EDTA at pH 4.1 and -0.520V v.s. S.C.E. in 0.05 M NTA at pH 6.3. In this paper, the effects of gelatine concentration and pH values was investigated. The half-wave potentials of common elements was determined and compared with the half-wave potential of Tl(I).
