지송운,김호성,양윤준,장재원 대한스포츠의학회 2004 대한스포츠의학회지 Vol.22 No.1

The purpose of this study was to compare the effect of AB slide™ on abdominal muscles with Crunch and Sit-up. Myoelectrical activities of Rectus abdominis muscles produced by AB slide™, Crunch and Sit-up were recorded. Healthy male aged from 17 to 36 years(23.0±5.9 yrs) were included fo the test. Surface electrodes were attached to upper and lower part of Rectus abdominis of the study subjects. Averaged integrated electromyography(AIEMG) and Normalized integrated electromyography(NIEMG) were recorded. The results are summarized as follows; First, the AIEMG of Sit-up were highest among them with insignificant difference statistically. Second, the NIEMG of upper part of Rectus abdominis were higher than the one of lower part with significant difference statistically(p<0.05). This phenomenon was same irrespective of the type of exercises. AB slide™ was not more effective than Sit-up and Crunch for strengthening of Rectus abdominis muscle. The upper part of Rectus abdominis was more activated than the lower part by all three exercises.

The results of the analysis showed that different ways of sampling methods were utilized in various studies in order to ensure the selection of unbiased samples under the circumstances of purpose and population of the survey.

액상요구르트의 沈澱安定化를 위한 硏究

양지영,이호재 釜山工業大學校 1994 論文集 Vol.36 No.-

In order to process the liquid yogurt without stabilizing agents, addition of rice bran extracts to medium, single or mixed cultures of various lactic acid bacteria were investigated. Addition of rice bran extracts stimulated acid production and propagation of L. casei N.Y. and its optimum concentration was 0.1%. Cultures prepared using 0.1% of rice bran extracts could be produced stable liquid yogurt product without stabilizing agents. But the use of rice bran extracts to liquid yogurt manufacture in a pilot scale was problematical in view of cost and law. The single or mixed cultures of L.casei L-14 and L. bulgaricus B-5b couldn't be produced stable product without stabilizing agents. L. casei J.Y. was produced 2.7 of acidity at 37℃ for 36 hrs to obtain cultures with high acidity and high number of viable cells. The liquid yogurt product prepared using cooled cultures of L. casei J.Y. was stable without stabilizing agents. But the liquid yogurt product prepared using stabilizing agents was unstable because of charge imbalane.

Sagittal appliance를 이용한 부정교합의 치료에 관한 증례

양규호,김지영,오희수 大韓小兒齒科學會 1991 大韓小兒齒科學會誌 Vol.18 No.2

Sagittal appliance is an active plate with expansion screws in the anteroposterior direction.It is used to advance the maxillary incisors and to distalize the maxillary molars,thereby to increase arch length. Sagittal appliance produces changes of tooth position in the surrounding bone by converting mechanical pressure into biological energy as the screws are activated regularly. We treated anterior crossbite,severe crowding,and submerged tooth with sagittal appliance. The results were as follows: 1. Dental crowding was relieved by some advancement of incisors and most of distalization of molar after extraction of second molars. 2. Anterior cross bite caused by immaturity of premaxilla was corrected by advancement of maxillary incisors and premaxilla and then facial profile was improved. 3. Irregular tooth arrangement and labial inclination of incisors occured during treatment will be corrected by fixed appliance. 4. Mesially titled first molar caused by submerged second primary molar was uprighted and lost space of secondprimary molar was regained by lower unilateral sagittal appliance.

본 연구는 예방적 레진 수복술에 전통적으로 사용되던 소와열구 전색제를 대신하여, 유동성 복합 레진이 사용될 경우의 타당성을 검토하기 위해 시행되었다. 비커스 미세경도를 측정하기 위해 직경 10 mm, 높이 3 mm인 11개의 시편을 제작하여 비커스 미세경도 측정기(FM-7, FUTURE-TEC Inc., Japan)를 이용하여 압입하중 50 gf, 유지시간 15초의 조건 하에서 측정하여 각 군의 평균값을 산출하였다. 표면조도를 측정하기 위해 칫솔마모시험기(Toothbrush abrasive machine K236, Tokyo Machine Co., Japan)로 4개의 시편 표면에 200 rpm의 속도로 4000회의 칫솔질을 시행한 뒤 표면조도형상측정기(Form Tahrsurf series 2, Rank Taylor Hobson Co., England)를 이용해 표면조도를 측정하였다. α=0.05의 유의 수준에서 Kruskal-Wallis rank test와 Mann-Whitney U test를 사용하였다. 또한 주사전자현미경으로 관찰하여 각 군의 마모 양상을 비교하여 다음과 같은 결론을 얻었다. 1. 비커스 미세경도 측정 결과 Filtek Z350 flowable(3M ESPE, U.S.A), Palfique Estelite LV(Tokuyama Dental, Japan), Ultraseal XT plus(Ultradent, U.S.A) 순으로 높게 나타났으며 모든 군 간에 통계적으로 유의한 차이가 있었다(p<0.0001). 2. 표면 조도 측정 결과, Ultraseal^(R), Estelite^(R), Z350^(R) 순으로 높게 나타났으나 통계적으로 유의한 차이는 없었다(p=0.116). 3. 마모되지 않은 표면과 마모가 일어난 표면을 주사전자현미경으로 관찰한 결과, 전색제인 Ultraseal XT plus와 유동성 복합레진인 Palfique Estelite LV, 나노필러를 함유한 유동성 복합레진인 Filtek Z350 flowable이 서로 다른 마모 양상이 나타나는 것을 볼 수 있었다. 이상의 결과를 토대로 할 때, 유동성 복합 레진이 전색제에 비해 물성적 측면에서 더 우수한 것으로 나타났다. This study was performed to compare the wear resistance of sealant and flowable resins for analyzing the effect of flowable resin as a sealant in preventive resin restorations. Specimens were made and Vicker's hardness number and surface roughness were measured. SEM observations of the polished and abraded surfaces were established. Kruskal-Wallis rank test and Mann-Whitney U test at the significant level of α=0.05 were used. The following results were obtained: 1. The microhardness was decreased among groups in following order: Z350(3M ESPE, U.S.A), Estelite(Tokuyama Dental, Japan) and Ultraseal(Ultradent, U.S.A). There were significant differences in all groups(p<0.0001). 2. The surface roughness was decreased among groups in following order: Ultraseal XT plus, Palfique Estelite LV and Filtek Z350 flowable, However, there is no statistically significant differences in roughness among Estellite, Z350 and Ultraseal at the significance level of α=0,05, with p=0.116 3. SEM observation of the unworn and worn surfaces revealed the qualitative differences in the wear appearance among groups. The results in this study indicate that flowable resin is better than sealant in aspect of physical properties.

The possibility that liver and kidney function is adversely affected by current levels of environmental exposure to cadmium (Cd) as investigated in adult men and women in the general population in Seoul. From February to August in 2001, blood and morning spot urine samples were collected from 136 not occupationally exposed group (age range 20~75 years) at 4 survey sites throughout Seoul. Liver and kidney function parameters in serum and urine were examined by conventional methods. The questionnaire included factors, i.e. sex, age, smoking, alcohol, diet habit etc. The geometric mean values for Cd in blood (Cd-B) were 1.43 μg/l. It seemed prudent to conclude that liver and kidney function as not disturbed by the current environmental exposure to Cd in study.

이지훈,육완이,양호연,하종현 대한방사선 방어학회 2002 방사선방어학회지 Vol.27 No.2

원자력발전소에서 주로 발생되는 금속폐기물인 탄소강을 중성염전해질인 1.7M의 황산나트륨(Na₂SO₄)과 질산나트륨(NaNO₃)을 이용하여 기존전해제염과 개선된 전해제염공정의 비교실험을 수행하였다. 양극은 인코넬, 음극은 티타늄으로 하여 상온에서 1시간동안 반응시켜 금속폐기물 모재의 weight loss, 두께변화, 전해질 내 침전물농도, SEM을 이용하여 제염전후의 금속폐기물 표면의 형상을 분석하였다. 실험결과 개선된 전해제염 적용시 전해질 종류별 전류밀도 변화에 따른 실험에서는 전류밀도가 0.1∼0.6A/cm²으로 증가함에 따라 1.7M의 황산나트륨 적용시 금속폐기물 모재의 두께변화는 0.48±0.005∼67.7±0.02um, 1.7M의 질산나트륨 적용시에는 0.06±0.005∼17.7±0.05로 나타나 같은 전류밀도에서 황산나트륨 적용시 금속폐기물 모재의 표면 제염효율이 더욱 높은 양상을 보였다. 또한 전류밀도 0.3 A/cm² 및 1.7M의 황산나트륨의 조건에서 개선된 전해제염 적용 시 9.8±0.01um의 금속폐기물 두께변화를 보여 기존전해제염 적용시인 3.7±0.03um의 금속폐기물 두께변화보다 2배 이상의 표면 제염효과를 보였다. Conventional and modified electrolytic decontamination experiment were performed in the 1.7 M solution of sodium sulfate and sodium nitrate for decontamination of carbon steel as the simulated metal wastes which have been produced in large amounts from nuclear power plants. Anode and cathode were used as inconel and titanium respectively. The reaction time and temperature were 1 hr and 25℃. The analyses were performed of the characteristics such as weight loss and thickness change of metal waste, suspended solid in electrolyte and SEM observation. In modified electrolyte decontamination system with increased current density ranged from 0.1 to 0.6 A/cm², the metal waste showed thickness changes of 0.48±0.005 to 67.7±0.02um in 1.7 M sodium sulfate and those of 0.06±0.005 to 17.7±0.05um in sodium nitrate. Metal waste in modified electrolyte decontamination system showed the thickness change of 9.8±0.01um while it reacted up to 3.7±0.03um in conventional system with 0.3 A/cm² of current density and 1.7 M sodium sulfate. Decontamination efficiencies of modified electrolytic process are much higher than that of conventional electrolytic process when both are applied to metal waste.
