  • This study was carried out at the CWC of Chosun university for the purpose of resistance performance improvement of planing hull, and the results of the tests were confirmed cooperatively with WJFEL. G/T 100 ton class planing hull form was selected, and the improvement of hull form including appendages were performed by using some model test techniques. The model test scope comprises resistance relative tests including wave profile observation, trim and sinkage measurement and flow visualization tests at full load and trial conditions for one bare hull and for two appended hulls. The final wedge and spray strip combined with improved hull form showed about 1.0 knot speed improvement at both of full and trial conditions, and outstanding improvement for fore wave phenomena.

  • This study was conducted to characterize the rapidly processed salt-fermented sandfish sauce added Bacillus coagurance KM-1 (RSSS) and commercial salt-fermented sandfish sauce (CSSS 1, 2). Contents of total nitrogen and amino nitrogen were higher in CSSS 1,2 than in RSSS (P<0.05). Total free amino acid contents of RSSS and CSSS 1,2 were 1,121.2±100 mg/100 g, 1,553.6±98.2 mg/100 g and 1,507.3±99.8 mg/100 g. Major free amino acid of RSSS was glutamic acid (194.4±17.3 mg/100 g), alanine (140.8±12.6 mg/100 g), lysine (135.1±12.1 mg/100 g), leucine (109.8±9.8 mg/100 g), aspartic acid (103.0±9.2 mg/100 g), valine (73.5±6.6 mg/100 g) in ordor. The samples were caused by their composition of the free amino acids rations, in which were umami, sweet and bitter taste in the salt-fermented sandfish sauce during fermentation. The Na was the largest mineral followed by K, Mg, P, Ca in the samples (P<0.05). Sensory evaluation result of samples, CSSS 1 was the highest than the others in overall acceptance.

  • 본 연구에서는 유황의 절연 특성 및 리튬 폴리 설파이드 용출로 인해 전지 수명 저하를 최소화하기 위해 ZIF67/rGO를 사용하였다. rGO로 포장이 된 ZIF67는 탄소 스펀지 내에 공간을 더 많이 만들어주며, 다량의 유황을 보관할 수 있다. 유황@ZIF67/rGO 복합체를 합성하고, 스펀지 형태로 제조함으로써 유황의 담지 능력을 향상시켰다. 그 결과로서 높은 초기용량을 보였으며, 약 1093 mAh g-1의 값을 나타내며 100사이클 후에 84%의 용량유지율을 보임을 확인하였다. 코발트와 탄소의 복합화를 통하여 유황과의 상호작용이 높아 ZIF67/rGO는 리튬유황전지의 양극 활물질인 유황을 담지하는 담지체로서의 높은 성능을 나타남을 확인하였으며, 높은 초기용량과 용량유지율이 개선되었음을 확인하였다.

  • In 1983, Sten H$\ddot{a}$kanson first reported the clinical safety and efficacy of retrogasserian glycerol injection as a treatment of typical trigeminal neuralgia in 96 of 100 patients during a follow-up period of 1~6 years. Since September 1987, we have injected sterile pure glycerol into the trigeminal cistern using an anterior percutaneous approach via the foramen ovale (H$\ddot{a}$rtel route) for treatment of tic douloureux in 12 patients who were suffering from attacks pain of following discontinuation of carbamazepine. The results were as follows; 1) Eight patients were completely free from pain attacks with a single dose of glycerol (0.4 ml). The remaining four patients needed a second dose (0.4 ml) several days later following the single dose. The degree of patient's subjective satisfaction by those injections was very good in 11 and fair in one. 2) During the follow-up period (1~13 months), persistent sensory deficit as determined by the pin prick test, appeared to be mild in 10 and moderate in one patient. There was no sensory deficit in one patient. further attacks of pain from those injections were still noted. 3) As a transient complication, there was headache in all patient, facial hematoma in 4, nausea and vomiting in two each, and vertigo and herpes simplex in one each. In conclusion, we confirmed that the above glycerol injections into the trigeminal cistern were clinically very effective as a treatment of tic douloureux even though the follow-up period was short.

  • 4가지 물질의 분말을 10배액, 100배액, 500배액, 1000배액, 1500배액, 2000배액을 농도별로 처리하여 목이버섯 균사생장과 균사밀도를 조사한 결과는 다음과 같다. Senna은 대조구에 비하여 10배액, 100배액, 500배액, 1000배액, 1500배액 2000배액의 6가지 처리 모두가 균사생장과 밀도가 좋았으며 그중 100배액이 가장 좋았다. L-citrulline 분말은 처리농도 500배액이 대조구에 비해 같은 기간 내에 7.86mm/15일이 더 빨리 자랐으며 균사밀도도 좋아 최적 희석배수를 나타내었다. L-carnitine 분말은 100배액은 대조구에 비해 균사생장이 3.4 mm/15일로 촉진되었으며 균사밀도도 촉진되었다. Garcinia cambogia 분말은 대조구에 비해 6가지 희석배수 모두 균사생장이 억제되는 경향을 나타내었다. 10배액의 가장 진한 희석배수에서 가장 균사생장이 억제되었고 1000배액은 거의 대 조구와 비슷한 경향을 나타내었다. 따라서 L-citrulline, L-carnitine, Senna, Garcinia cambogia 순으로 균사생장과 균사밀도에 촉진적으로 작용하였다.

  • 이 연구에서는 TEMPO와 NaBr의 농도 및 온도가 옥수수 전분 내 1차 알코올기의 선택적 산화 반응에 미치는 영향을 조사하였다. TEMPO와 NaBr 및 온도의 수준이 증가함에 따라 반응 시간은 감소되는 경향을 나타내었다. TEMPO, NaBr 및 온도의 수준이 각각 1.7 mM/100 mM AGU, 100 mM/100 mM AGU 및 $14^{\circ}C$까지는 이들의 수준이 증가함에 따라 반응 시간이 급격히 단축되었으나, 이 이후의 수준부터는 단축정도가 적었다. 수율은 NaBr의 수준이 증가함에 따라 감소하였고, TEMPO와 온도는 수율에 큰 영향을 주지 않는 것으로 나타났다. 선택성은 NaBr의 농도와 온도가 각각 100 mM/100 mM AGU와 $6^{\circ}C$까지는 유의적인 차이를 보이지 않았으며, 이 이후의 수준부터 NaBr 및 온도가 증가함에 따라 유의적으로 감소하는 것으로 나타났다.

  • Objective : Despite the recent progress that has been made in intracerebral monitoring, it is still difficult to quantify the exact extent of primary brain damage after severe head injury. In this work, we investigate the role of S-100B protein as a serum marker of brain damage after severe head injury. Methods : 21 patients with severe head injury [GCS score <9] were selected for this prospective study. A venous blood sample was taken as soon as possible after head injury and the serum concentration of S-100B protein was measured daily for five consecutive days. The serum level of S-100B protein was compared with the patients' outcome. The outcome was measured twice, at hospital discharge and after 6 months of follow-up using the Glasgow Outcome Scale[GOS]. Results : Those patients who died within two weeks [after head injury] had a significantly higher serum S-100B value than those who survived [median, 9.64ug/L versus 2.91ug/L]. Seven [78%] of the nine patients who died had a maximum S-100B value of 2ug/L or higher, while three [25%] of the twelve surviving patients showed a maximum S-100B protein value of more than 2ug/L [P<005]. Conclusion : These results indicate that S-100B protein appears to be the most reliable index for estimating the extent of brain damage.

  • Purpose: This study was aimed to investigate the colony counts by different disinfecting processes and duration of the operation for humidifiers in an intensive care unit (ICU) in Busan. Method: The four steps of disinfecting process were taken with four different humidifiers according to the use of disinfectant (1:100 $Deconex^{(R)}$ 50FF/nothing) and refilling water (tap water/distilled water). First, the colony counts using water sample from wick was conducted at 0 hr, 24 hr, and 48 hr respectively after turning on the humidifiers. Next, the colony counts using waterdrop from the outlet was done at 0 hr, 24 hr, 48 hr, and 72 hr respectively after turning on the humidifiers. Result: No colony was counted after disinfecting with 1:100 $Deconex^{(R)}$ 50FF until 72 hr after turning on the humidifiers. However, without disinfecting with $Deconex^{(R)}$ 50FF, the colony count was increased in the humidifiers from 24 hr after turning on the humidifiers. The result was the same regardless of the refilling water. Conclusion: According to the results, the study found that disinfection of humidifiers in the ICUs with 1:100 $Deconex^{(R)}$ 50FF every 72 hr is effective to remove general bacteria.

  • In this paper, we investigated the friction characteristics of $W100^{\circ}{\o}L25m$ ellipse type surface pattern, on bearing steel. These characteristics are researched by utilizing a pin-on-disk wear test machine, under various velocities and other conditions. The reduction of friction is a necessary requirement for the improved efficiency of industrial parts. As the speed increases, there is a decrease in the effect of the dimple of friction characteristic in low velocity, with substantially little change to density. Conversely, as the load increases, the test direction of ellipse type dimple pattern, resulting in a difference in the texture of these two components. At a dimple density of 7.5% the friction characteristic is easily demonstrated, with a consistent change in both speed and load.
