The purpose of this study is to find out the optimal mixing ratios of amounts of Mal-Cha for preparation of Jeung-Pyun through Sensory, Mechanical characteristics test. The proximate composition of Mal-Cha were a 5.46±0.15% of moisture, 4.43±0.11% of total nitrogen, 7.52±0.21% of crude lipid, 8.74% of crude fiber, 8.51±0.09% of ash. Overall quality in 1.5% Jeung-Pyun showed the worst of 0, 0.5, 1.0% Jeung-Pyuns(p<0.05), especially 1.0% Jeung-Pyun had relatively the best overall quality. But the sweetness, sourness, flavor, hardness, moistness were not significantly different among all Jeung- Pyuns. 0, 0.5, 1.0% Jeung-Pyuns showed the best quality of Jeung-Pyun through sensory, mechanical property. Total color difference was increased as amount of Mal-Cha(p<0.001).

Few topics in operative and perioperative patient management generate more controversy than that of appropriate fluid and electrolyte therapy. especially, controversy has swirled around colloid vs crystalloid therapy and the composition of administered fluids, agreement among clinicians as to what fluid therapy is appropriate, and in what amount, is rare. This controversy likely will be enhanced by Arieff' s provocative article. He described 11 adults and 2 pediatric patients. All developed fatal postoperative pulmonary edema, seemingly caused solely by excessive postoperative fluid administration. From January 1999 to December 1999, we investigated 24 patients, which were operated by orthognathic surgery, about the intraoperative fluid therapy and the associated effect in orthognathic surgery, which is regarded as one of the major surgery of oral and maxillofacial surgery. First, They were devided into two groups, that is one-jaw surgery and two-jaw surgery, and each groups were devided by intraoperative fluid volume of 8ml/kg/hr. Subjective assesment was collected through use of a series of 3 questionnaries. In each questionnaire, a 5-point Liekert scale was used far assessment of following parameters of recovery from anesthesia: headache, dizziness, drowsiness, nausea/vomiting, thirst. The patient completed questionnaire 1 at 4 hour after surgery, questionnaire 2 was completed at 24 hours after surgery, and questionnaire 3 was completed at 48 hours after surgery. This study demonstrated that appropriated perioperative rehydration decreases postoperative adverse outcomes and improved the patient's perception of the postoperative period.

본 연구에서는 Aramid 섬유쉬트 부착공법의 역학적 거동을 평가하기 위해 14개의 구형보를 제작하여 보강길이, 보강두께 등을 실험변수로 휨 거동 실험을 실시하였다. 보강재 부착 이전의 시험체에 대한 선행하중의 재하는 없었으며, Aramid섬유가 보강되지 않은 보 2개와 1ply로 보강된 길이 100cm, 200cm 각각의 보 2개와 2ply로 보강된 길이 100cm, 200cm 각각의 보 2개와 3ply로 보강된 길이 100cm, 200cm 각각의 시험체의 거동을 비교하여 하중-처짐관계, 하중-변형률관계, 파괴형상 등을 파악하였다. 실험 결과 아라미드 섬유쉬트로 보강한 시험체의 최대파괴 하중과 휨모멘트강도는 보강하지 않은 시험체와 비교하여 100cm의 경우 1ply 일 때 119%, 2ply 일 때 131%, 3ply 일 때 152%정도의 효과가 나타났으며, 200cm의 경우 1ply 일 때 149%, 2ply 일 때 159%, 3ply 일 때 166% 나타났으며, 부분적인 보강보다는 전면보강시험체의 보강효과가 크게 나타났다. In this study, to verify the effects of reinforcing with sticking thickness and length of Aramid Fiber Sheet, I compared movements of experimental beams one reinforced by 100cm, 200cm length of 3ply, two beams reinforced 100cm, 200cm length of 2ply, two beams reinforced 100cm, and 200cm length of 1ply and two beams none-reinforced by Aramid Fiber Sheet and performed experiments of relationships between load-displacement, load-deflection and experiment about figure of destruction. As a result of study ; related to the max. failure load, reinforcing effects were improved by 119% when using 100cm of 1ply, 131% using 100cm of 2ply, 152% using 100cm or 3ply, 149% using 200cm of 1ply, 159% using 200cm of 2ply and 166% when using 200cm of 3ply. As you can see above effect of whole reinforcements was much better then that of partial reinforcing and We can see effect of reinforcing is not improved proportionally according number of ply even though effect of reinforcing is improved when the number of ply is increased.

This study was managed to develope the existing numerical calculation model of near shore current and wave fields where wave and current coexist around shallow water region, and analyse their problems. Until now, nearshore current model that include longshore current and on-off shore current had shown wave characteristic based on regular wave theory. In this study, however, nearshore current characteristic was changed by directional dispersion. So the effect of directional dispersion of multidirectional irregular wave was examined numerically by the basic study of nearshore current calculation due to multidirectional wave that was driving force of pollutant material at shallow water region.

A longitudinal study was conducted to determine the physical maturity characteristics of athletes engaged in the following extracurricular sports activities over the three-year junior high school period : basketball(N=40), baseball(N=130), volleyball(N=54), soccer(N=86) and a non=athletic group(N=37) which did not participate in sports. Each athlete's maturity was determined from the age of maximum increment in height (MIA) of each individual. Longitudinal stature measurements were recorded annually in April for 12 years period from 6 to 18 years of age. The study yielded the following results : 1. The MIA distributions of all the sporting groups were distinctly larger than that of the non-athietic group, increasing with each chronoiogical age step on the distance curve and annual increase in height curve. The MIA mean value for the soccer group was significantly higher(P<.05) than those of the non-athletic and all the other sporting groups. 2. The soccer group was significantly slighter(p<.05) in stature than all the other sporting groups. 3. Subjects who played baseball throughout high school reached physical maturity earlier than those who only played throughout junior high school. However, those who continued to play soccer throughout high school reached maturity later than those who only played throughout junior high school.

The authors experienced 6 cases of Dimecron intoxication, an organophosphate, that required mechanical ventilator treatment. Among 6 cases, 4 cases were intoxication due to suicidal attempt and 2 cases were due to accidental exposure. Among 4 cases of intoxication due to suicidal attempt, only one patient recovered even after aggressive treatments using gastric lavage, mechanical ventilation, atropine and PAM(pralidoxime). Two cases of intoxications due to accidental exposure, 1 case needed mechanical ventilation. Both cases were recovered without any sequele, however. Organophosphate, especially Dimecron, showed high rates of resfiratory muscle paralysis and mechanical ventilator support. The mortality rate of organophosphate agents can be decreased by education, wearing protectors, and aggressive mechanical ventilator treatment when respiratory failure develops.

Background: Recently, the autoimmune process of vitiligo has been further identified by the demonstration of CD8+T cells playing a major role in spreading vitiligo. Although the decreased risks of skin cancers in patients with vitiligo has been found, the risks of internal malignancy have not been assessed yet. Objectives: To determine the risks of internal malignancy in patients with vitiligo. Methods: A population-based cohort study was conducted using the Korean NHI Claims database from 2007 to 2016. All patients with vitiligo aged ≥20 years were identified, and age- and sex- matched controls selected from patients without vitiligo. Outcomes of interests were the incidences of internal malignancy since the enrollment. Results: A total of 101,078 patients with vitiligo and 202,156 controls without vitiligo were enrolled. The overall risk of internal malignancy was 612.9 and 708.9 per 100,000 person-years in vitiligo patients and controls, respectively, and was significantly decreased in patients with vitiligo (HR 0.857, 95% CI 0.823-0.893) after adjustment for potential confounders. In subgroup analyses, vitiligo was significantly associated with the reduced cancer risks of stomach (HR 0.838), colon and rectum (HR 0.617), lung (HR 0.748), ovary (HR 0.617), and leukemia (HR 0.592) (all P < 0.003). Conclusion: The autoimmune nature of vitiligo might protect patients with vitiligo from the development of various internal malignancies.
