Changes of lipid oxidation and antioxidative activity in modified oleoresin during heat treatment and storage were investigated. Lipid oxidation occurred somewhat to oleoresin red pepper after heat treatment for 5 hours at 150℃ and 200℃, whereas in the heat treatment at 50℃ and 100℃, occurred in little. During heat treatment for 5 hours at 100℃, oleoresin red pepper had a moderate antioxidation effect, but its antioxidation effect at 200℃ was not shown due to degradation of capsaicin. And oleoresin red pepper greatly inhibited the oxidation of soybean oil during storage at 25℃ and 40℃.

창자파래(Enteromorpha intestinalis)로부터 Dimethyl-β-propiothetin 추출

배태진,강동수,최옥수 한국식품영양학회 2000 韓國食品營養學會誌 Vol.13 No.4

해조류에서 생합성되는 3급 함황화합물인 DMPT를 창자파래로부터 추출하기 위하여 시료의 상태, 용매의 극성. 초음파 처리. boiling 및 autoclaving 처리에 의한 추출조건을 검토하였다. 용매추출, 초음파 처리후 용매추출, 열수추출 및 가압 열수추출법을 이용하여 창자파래로부터 DMPT를 추출한 결과, 초음파 처리후 가압 열수처리한 경우가 가장 효과적이었고, 다음으로는 초음파 처리후 열수처리하는 방법이었다. 창자파래로부터 DMPT를 추출해내는 최적조건으로 분말시료에 물과 acetone (2:1, v/v)의 혼합용매를 15배량 가하여 초음파 처리 후 121℃에서 60분간 autoclaving하는 방법으로서, 이때 추출된 DMPT 함량은 시료 g당 311.200ng이었다. 창자파래에서 추출한 DMPT 수용액을 조제하여 온도별로 저장시킬 때 DMPT 분해에 의한 DMS의 발생량은 저장온도에 비례하여 증가되었지만 저온에서는 매우 낮은 분해율을 나타내었다. DMPT 1㎎을 저장하였을 때의 잔존율은60℃ 저장의 경우78.5%로 고온에서는 다소 불안정하였으나 0℃에서는 DMPT의 잔존율이 99.8%로 매우 높게 나타났다. 창자파래에서 추출한 DMPT 수용액을 30℃에서 방치하였을 때 pH가 5 이하의 산성영역에서는 DMPT의 분해가 거의 일어나지 않았으나 pH가 올라감에 따라서 분해가 서서히 일어나기 시작하여 pH 9.5에 이르러서는 DMS의 양이 급속하게 증가하였다. The DMPT produced by marine algae is the main biogenic precursor of oceanic DMS. Also, DMPT is an efficient stimulant for growth, feeding, and body movement of fish and striped prawn, and appears to play a physiologic role as an osmoprotectant in algae. This study was focused on the extraction of dimethyl-β-propiothetin as bioactive substance from green seaweed. Identification and quantification of dimethyl-β-propiothetin were measured by headspace gas chromatography after conversion to dimethyl sulfide by treatment with saturated NaOH solution. Dimethyl-β-propiothetin was extracted through various processes (solvent extraction, ultrasonication, boiling and autoclaving) from Enteromorpha intestinalis. The content of dimethyl-β-propiothetin extracted by autoclaving treatment showed higher than those of various extraction methods. Dimethyl-β-propiothetin content in extract of Enteromorpha intestinalis was 311,200ng/g after autoclaving at 121℃ for 60min. Dimethyl-β-propiothetin in extract of Enteromorpha intestinalis was comparatively stable under low temperature. The retentions of dimethyl-β-propiothetin content in extract of Enteromorpha intestinalis were 75.8∼99.8% by incubation at 10∼60℃ for 2 hours. Chemical decomposition of dimethyl-β-propiothetin was observed under laboratory conditions at pH values higher than 9.5.

배옥석,박영관,정정길 啓明大學校 醫科大學 1988 계명의대학술지 Vol.7 No.1

Severe pain experienced by patients following any anal operations has been well known to the surgeons and patients. Patients are often reluctant to undergo necessary operations because of the fear of this pain. During the period between January 1, 1987 and December 31, 1987, a total of 45 patients underwent anal operations under intrathecal or epidural anesthesia. Morphine was added to the usual anesthetics at the time of anesthesia: 0.25ㅡ0.5mg for intrathecal anesthesia and 2ㅡ4mg for epidural anesthesia. Postoperative pain was completely absent from 7 to 18 hours with the addition of morphine. There was no complications related to the addition of morphine including respiratory depression. The severity of postoperative pain depends on the operative technique and postoperative use of analgegics. The addition of morphine during intrathecal or epidural anesthesia showed definite benefit for the control of postoperative pain after anal operations.

"King Lear"에 나타난 복식 이미져리 硏究

배수정,김옥진 全南大學校家政科學硏究所 1993 生活科學硏究 Vol.3 No.-

The aim of this article is to make a better stage costume by reviewing and analyzing that of King Lear by Adrian Noble with applying clothing imagery to this play. In a way of research, the clothing imagery is to be studied at first, and then, with it being compared the clothes actually worn by Adrian Noble. The clothes in King Lear represent the values of society, of status quo, of an socially conceived external morality, while nakedness is the traditional image of unadorned truth. The madness of King Lear and the lost of throne is shown in nakedness by taking off King's clothes one by one. In Edar's case, the process of restoring his positions and regaining his identity was revealed in taking a better clothes. The rise of status in Edmund was symbolized by changing from commons to more gorgeous clothes. The stage costume of King Lear at Stratford in 1993 is limited in use of ornaments and colors, and transformed into a very simple one, and also designed to easily understand the personal relationship by attaching main colors to similar personality group. In the early part, the costume of Lear was changed from formal suits of shirts, veste and trousers and coat to shirts, veste and trousers, and he was falled into a distressful mental state with his button of veste opened, and thereby he was in wearing only shirts and trousers by stripping veste. Eventually Lear go in madness by being decorated with weeds with buttons of shirts opened. This corresponds with thr dramatic meaning that Lear gains his mental awareness while undergoing materialistic loss. The clothes of Edgar was formal suits of shirts, trousers, veste and coat as he was a noble, and he was in a state of wearing only branket when disguised as a poor Tom. When disguised as a farmer he was wearing only ragged trousers and long shirts and was same in clothes as a knight. This seems that the process of wearing a clothes of knight was treated as suggestive and abridged in showing the play. The clothing imagery of King Lear by Adrian Noble showed simple and modern styled clothes, contrasted with that of Shakespearean period. And it corresponds with the dramatic meaning basically. This play also shows a production technique that was planed to express the suggestive imagery without change of clothes by a abridged production technique and therby deliver the intention of Shakespeare to the spectators.

裵玉錫,黃樹寬,金亨鎭,朱永恩 慶北大學校 醫科大學 1982 慶北醫大誌 Vol.23 No.2

20∼22歲의 男子大學生 61名을 硏究對象으로 하여 選手群(21名)과 非選手群(40名)으로 區分하였다 運動負荷는 rebouner에 垂直뛰기를 一分間에 80回程度로 3分동안 實施했으며, 運動後 恢復期 1, 3, 5, 10 및 20分에서 心搏數, 血壓, 呼吸數의 恢復樣相을 觀察하였다. 이로써 체력단속이 恢復期의 心肺機能에 미치는 影響을 分析하고 나아가서 恢復期의 心肺反應이 體力을 評價하는 指標가 될 것인가를 알고자 試圖한 本 硏究結果를 要約하면 다음과 같다. 安靜狀態의 心搏數는 選手群이 非選手群에 比해서 有意하게 낮았으며 血壓 및 呼吸數는 別 差異가 없었다. 運動負荷後 心搏數의 恢復은 選手群은 恢復 1分에 86.4±3.22回로서 非選手群의 118.0±2.81回에 比해 有意하게 낮았고, 兩群 모두 恢復初期에는 急速한 恢復을 보였으며 選手群이 非選手群에 比해 繼續有意하게 낮은 값으로 빠른 速度로 恢復되었다. 運動負荷後 收縮期血壓의 恢復樣相은 選手群이 非選手群보다 繼續 낮은 값으로 恢復되었으며, 特히 恢復 1分에 選手群은 161.2±1.78mmHg로 非選手群의 174.1±3.41mmHg에 比해 有意하게 낮았다. 兩群 모두 恢復初期에 急速히 恢復하여 恢復10分에는 安靜狀態로 恢復되었다. 그리고, 擴張期血壓은 非選手群은 期動後 安靜狀態보다 有意하게 높았으며, 選手群은 오히려 安靜狀態보다 낮았다. 平均動脈壓은 恢復初期에 選手群이 非選手群보다 높은 값으로 恢復되었으나 恢復10分부터는 거의 같은 값으로 恢復되었다. 脈壓은 選手群이 非選手群에 比해 繼續 有意하게 낮은 값으로 恢復되었다. 運動負荷後 呼吸數는 恢復 1分에 選手群에서는 27.1±1.23回로 非選手群의 35.5±1.17回에 比해 有意하게 낮았고, 兩群 모두 恢復 1,3分에 急速히 恢復되었으며, 選手群이 非選手群에 比해 繼續 有意하게 낮은 값으로 恢復되었다. 本硏究結果를 綜合하면 rebounder 運動負荷後 選手群의 心搏數, 血壓 및 呼吸數가 非選手群에 比해 有意하게 낮았으며, 그 恢復速度도 빨랐다. 특히 心搏數는 選手群과 非選手群 사이에 恢復初期부터 恢復 20分까지 繼續 有意한 差異를 나타낸 점은 體力을 客觀的으로 評價하는 重要한 資料가 될 것으로 思料되는 바이다. Sixty-one male subjects aged between 20-22 years were divided into the athletic and non-athletic groups. Exercise was performed as vertical jump on a rebounder at 80 times per min for 3min. The heart rate, blood pressure, and respiratory rate were measured at 1, 3, 5, 10, and 20min after exercise in an effort to analyze the effect of the physical training on the cardiopulmonary function during the recovery period, and to find out if the cardiopulmonary responses during recovery period can be an index of physical fitness. The results are summarized as follows. In resting state, the heart rate was significantly lower in athletes than in non-athletes, while blood pressure and respiratory rate showed no significant difference between the two groups. The heart rate at 1min after the exercise was 86.4±3.22 in athletes which was significantly lower than 118.5±7.85 in non-athletes. The heart rate at the initial stage after exercise showed a rapid recovery in both groups. In athletes, it showed a rapid recovery to reach a significantly lower level than that of non-athletes. The systolic pressure was lower in athletes than in non-athletes throughout the recovery period. In particular, systolic pressure at 1min after the exercise was 161.2±1.78 mmHg in athletes which was significantly lower than 174.1±3.41mmHg in non-athletes. Systolic pressure at initial stage after the exercise showed a rapid recovery, and the resting value was retored in 10 min in both groups. Diastolic pressure during the recovery period was significantly higher in non-athletes and lower in athletes than the resting level.

배옥석,김형진,박재식,주영은 慶北大學校 醫科大學 1990 慶北醫大誌 Vol.31 No.3

고등학교 운동선수에서 최대하 treadmill 운동시험시 심폐기능의 변화를 구명하고 운동부하, 운동시간 및 심박수로부터 산소섭취량을 추산할 수 있는 회귀방정식을 유도하고자 15∼18세의 남자 고등학생 운동선수 14명과 비운동선수 16명을 대상으로 하여 Bruce법에 따라 treadmill 상에서 최대 운동능력의 80%에 해당하는 최대하운동을 실시하고 운동전, 운동중 및 운동후에 심박수, 혈압, 분시환기량, 탄산가스생산량 및 산소섭취량을 측정하였으며 운동 전후에 폐환기역학 검사를 시행하였다. 심박수는 선수군에서 안정시의 71.9±1.3회로부터 운동중 178.0±2.0회까지 증가하여 최대심박수의 81.2±2.3%에 달하였고 비선수군에서는 안정시의 81.8±2.4회로부터 182.6±1.1회까지 증가하여 최대심박수의 79.6±2.0%에 달하였다. 선수군의 심박수는 비선수군에 비해 전 실험기간에 걸쳐 유의(P<0.01)하게 낮은 값을 유지하였다. 분시환기량은 선수군에서 안정시의 5.1±0.6 L/min로부터 운동중 63.0 L/min까지 증가하였고 비선수군에서는 안정시의 5.2±0.5 L/min로부터 51.2 L/min 까지 증가하였으며 양군 사이에는 유의한 차이가 없었다. 산소섭취량은 선수군에서 안정시 1.0±0.4 ㎖/㎏/min로부터 운동중 32.6 ㎖/㎏/min까지 증가하여 최대산소섭취량의 72.9%에 달했으며 비선수군에서는 안정시 1.4±0.3 ㎖/㎏/min로부터 28.9 ㎖/㎏/min까지 증가하여 최대산소섭취량의 70.3%에 달하였다. 선수군의 산소섭취량은 비선수군에 비해 계속 낮은 경향을 보였다. Treadmill 속도 및 경사도와 산소섭취량 간의 중회귀분석 결과 중상관계수 0.9998로서 높은 상관관계를 나타내었다. Bruce법에 따른 운동시간과 산소섭취량 간의 회귀분석 결과 1차함수 회귀식에 대한 상관계수는 0.999였으나 3차함수 회귀식에 대한 상관계수는 0.99999로서 극히 높은 상관관계를 나타내었다. 심박수와 산소섭취량 간에는 상관계수 0.998 및 0.992로서 대체로 높은 직선적 상관관계를 나타내었다. 폐기능검사 결과 안정시 FVC, FEF_(0.2-1.2L), FEF_25% 및 MVV는 선수군에서 비선수군에 비해 유의(P<0.05)하게 높았다. 운동후 폐기능검사 성적은 비선수군에서는 안정시보다 저하된 경향을 보인데 비해 선수군에서는 향상된 경향을 보였다. The cardiorespiratory function was evaluated during and after a submaximal treadmill exercise and some regression equations were derived for estimation of oxygen uptake from exercise load, exercise time and the heart rate. A total of 30 high school boys, of whom 14 were athletic and 16 non-athletic, performed a submaximal treadmill exercise according to the Bruce protocol to the point when 80% of their maximum exercising capacity were reached. The heart rate, blood pressure, minute ventilation, CO_2 production and O_2 uptake were measured before, during and after exercise, and the pulmonary function test was performed before and after exercise. Heart rate was increased from 71.9±1.3 beats/min at rest to 178.0±2.0 during exercise which was 81.2±2.3% of the maximum heart rate in athletes, and from 81.8±2.4 beats/min at rest to 182.6±1.1 which was 79.6±2.0% of its maximum in non-athletes. Athletes showed significantly (P<0.01) lower heart rate than non-athletes throughout the experimental period. Minute ventilation was increased from 5.1±0.6 L/min at rest to 63.0 in athletes and from 5.2±0.5 L/min to 51.2 in non-athletes. Athletes and non-athletes showed no significant difference. Oxygen uptake was increased from 1.0±0.4 ㎖/㎏/min at rest to 32.6 which was 72.9% of maximum oxygen uptake in athletes, and from 1.4±0.3 ㎖/㎏/min to 28.9 which was 70.3% of the maximum in non-athletes. Athletes showed consistently lower oxygen uptake than non-athletes. Multiple regression analysis between treadmill speed and grade and the oxygen uptake showed a high correlation coefficient of 0.9998. A first order regression analysis between exercise time and oxygen uptake showed a correlation coefficient of 0.999, while a third order regression analysis showed an extremely high correlation coefficient of 0.99999. The heart rate and oxygen uptake showed a linear regression with a reasonably high correlation coefficient of 0.998 and 0.992. The pulmonary function test revealed significantly(P<0.05) higher FVC, FEF_(0.2-1.2L), FEF_25% and MVV at rest in athletes than in non-athletes. After exercise, athletes showed enhanced pulmonary function compared with the resting state while non-athletes showed more or less decreased.

한국국민학교 학생집단에서의 회충감염율 분석

전오배,강신영,심태섭 중앙대학교 의과대학 의과학연구소 1981 中央醫大誌 Vol.6 No.1

The soil-transmitted and contagious helminthes, such as Ascaris lumbricoides, whipworm, hookworm and pinworm are the commonest and the most widespread human parasites in Korea. However, the first intestinal nematode infection has been taken into account as the great endemic parasitic disease in this country. Data cited from KAPE(korean Association for Parasite Eradication) were analyzed on the bases of infection rate, fertilized ova passers/unfertilized ova passers and the evaluation of the effect of mass control on primary school-children during the past 10 years from 1969 to 1978. The results were summarized as follows: 1) The overall prevalence of Ascaris infection was decreased from 57.1% in 1969 to 22.8% in 1978 and the cumulative percent of decrease during that period was 34.3% and the mean annual decrease rate represented as 3.8%. 2) The cumulative rate of decrease in primary school children was in the range of 32.2-36.8% by school year. 3) The prevalence of Ascaris infection of primary school-children in rural area was 60% in 1969, it decreased to 17-30% in 1978, while the rates tangibly dropped to about 10% level in urban primary-school children. 4) The positive rate of A. lumbricoides in 1973 was composed of fertilized and unfertilized ova passers in the ratio of 43.l% :9.2% (F/U=4.68). Five years later in 1978 it changed to 3.22. 5) By applying the present results to the statistical model of Hayashi(1977), the theoretical infection rate per month and cure rate per treatment were computed as 2.54% and 33.3% respectively in primary-school children during the past 10 years. And the observed data were coincide with the theoretical data. From the above statistical analyses, it is distinct that the prevalence and F/U ratio remarkably decreased by efficient mass control on primary school children during the past 10 years from 1969 to 1978.

국내 대기 중 독성 휘발성 유기화합물의 오염 특성(Ⅱ) : 계절 및 지역적 변동 Seasonal and Locational variations

백성옥,김배갑,박상곤 한국환경독성학회 2002 환경독성보건학회지 Vol.17 No.3

This study was designed to investigate the characteristics of atmospheric concentrations of toxic volatile organic compounds (VOCs) in Korea. Target compounds included 1, 3-butadiene, aromatics such as BTEX, and a number of carbonyl compounds. In this paper, as the second part of the study, the seasonal and locational concentrations of atmospheric VOCs were evaluated. Sampling was conducted seasonally at seven sampling sites, each of them representing a large urban area (commercial and residential), a small urban area (commercial and residential), an industrial area (a site within the complex and a residential), and a background place in Korea. In general, higher concentrations were found in the petro-chemical industrial site than other sites, while VOCs measured in commercial (heavy-traffic) sites were higher than residential sites. Seasonality of VOCs concentrations were not so much clear as other combustion related pollutants such as sulfur dioxide, indicating that the VOCs are emitted from a variety of sources, not only vehicle exhaust and point sources but fugitive emissions. Except the industrial site, the concentrations of VOCs measured in this study do not reveal any serious pollution status, since the levels did not exceed any existing ambient standards in the U.K. and/or Japan. However, the increasing number of petrol-powered vehicles and the rapid industrialization in Korea may result in the increased levels of VOCs concentrations in many large urban areas in the near future, if there is no appropriate programme implemented for the control of these compounds.
