  • 본 연구에서는 E. pellita와 A. mangium 용기묘를 대상으로 시비 처리에 따른 광합성, 엽록소 형광반응, 엽록소 함량 등의 생리적 특성 및 생장 특성 변화를 조사 분석하여 열대림 두 수종에 대한 시설양묘과정에서의 최적 시비 조건을 구명하고자 연구를 실시하였으며, 다음과 같은 결론을 얻을 수 있었다. 시비처리에 따른 E. pellita의 광합성 능력, 광화학 효율 및 엽록소 함량은 $1g{\cdot}l^{-1}$ 처리구에서 가장 우수하였으며, $2g{\cdot}l^{-1}$에서는 과량 시비로 인한 생육저하 현상으로 오히려 감소하는 경향을 나타냈다. A. mangium은 $2g{\cdot}l^{-1}$ 처리구에서 가장 우수한 광합성 능력, 광화학 효율 및 엽록소 함량을 보이면서 시비수준이 높을수록 우수한 능력을 나타냈다. 두 수종 모두 적정 시비 조건에서 높은 엽록소 함량과 광화학 효율에 의해 활발한 광합성 활동이 이루어졌다. 즉, 양분 조건에 따라 광합성 기구가 유동적으로 변하는 것을 알 수 있다. 근원경과 간장 생장 및 물질생산량 또한 E. pellita는 $1g{\cdot}l^{-1}$, A. mangium은 $2g{\cdot}l^{-1}$ 처리구에서 가장 우수하였으며, 생리적 특성과 같은 경향을 보였다. H/D율과 T/R율은 시비 처리구가 무시비 처리구보다 높은 값을 보였지만, 시비 처리 간 유의적 차이는 나타나지 않았다. 묘목품질지수는 두 수종 모두 위 결과와 같이 수종별로 적정 시비 처리구에서 가장 높았으며, 적정 시비 처리에 의해 생산 된 묘목 우수한 형질을 나타낸 것이다. 본 연구 결과를 종합해 보면, 열대 수종인 E. pellita와 A. mangium의 용기묘 양묘 시 시비 처리에 따른 양분 조건에 의한 생리 및 생장 특성의 변화를 볼 수 있었다. 양분 부족은 광합성 기구의 활동 감소에 의한 생장 저하가 초래되어 불량한 묘목이 생산되는 과정을 볼 수 있다. 즉, 양묘과정에서 수종별 양분 요구도에 맞는 생육환경조절은 시설양묘시업에 의한 건전한 묘목을 대량 생산함과 동시에 조림과정에서도 높은 활착과 생장으로 우수한 조림성과를 기대할 수 있을 것으로 판단된다. 또한 일률적인 시비를 실시하는 것이 아니라, 기간별 상대생장량을 조사하여 수종별 생장패턴에 따라 기간별로 양분 요구량에 맞는 집중, 효율적인 시비를 실시할 수 있을 것으로 기대된다. 이에 띠라 양묘과정에서의 환경적 측면과 함께, 비용 측면에서 이점이 있어 경제적으로도 묘목 생산비를 절감할 수 있을 것으로 판단된다.

  • This thesis is a study on the kaftan styles iin Asia. The purpose of he study was to examine the origin o the kaftan concentrating on the history and cultural backgrounds of nomads in he Western Central and North Eastern Asia. Secondly for more thorough study and expla-nation on how these kaftans contributed to East-West trade along the silk road. wall paintings and miniature illuminations along Oasis roads persia and Saracen period were compared, Also real kaftans were compared and analyzed the characteristics of Western (Turkey palestine) Central(Kazakistan Uz-bekistan Tadzhistan Qyrgyztan Turkmenistan) and the North Eastern Asian(Mongol) area. Thirdly an attempt has been made to provide the North Eastern Asian(Mongol) area. Thirdly an attempt has been made to provide the style classifications according to their peculiarities of the various kaftans as well as how kaftan gave important influences on custumes of different religious sects. The kaftan is a long coat-like garment with front openings fastened with long sash having an extra long sleeves which were worn by middle and high class nomadics throughout the West Central and North Eastern Asia This type of kaftans were a basic clothing for nomadics since they were constantly moving fromone to another areas on their horse back riding. They also wore tight trousers with boots. Kaftans seem to be originated from nomads of Steppe around B.C. 800 On B. C 400 west asian areas such as Solokha Kul-oba Kulogan had pictures sculptues on vases showing kaftans of half coat type length with front opening tied with band. Also the materials used were the products of animals such as wool or felt with animal designs showing Scythian nomads. In the North Eastern Asia Hsiung-Nu were active in Kazakha North Altai and Mongol The Clothing and fabrics exfavated near Noin-ula Pazyrik showed many samples of kaftan with trousers with other interment be-longings with a corpse around B.C 300 to A. D 100 when trades along the silk roads were proven by many historians Kaftans excavated in this area wore red front opening silk materials which suggesting settling down of nomads. in he central Asia Dol-gull near Altai mountain area were mainly miners who later had many trades with Persia and Bizantine. After Dol-gull Bezeklik temple Samarkant Kizil cow Budda sculture wall paintings of Astana tomb showed typical kaftan of this re-gion. These were both hip covered length as well as long coat with narrow sleeves. Es-pecially they had different color band fron the main kaftan with grogeously and splendously designed silk. In perusia during A. D 1400 to 1600 minia-ture illumination showed kaftan as a high class symbol more than clothing purpose. They had best quality silk with extra long sleeves draping and had a layers of kaftans one on top of anther as a symbol of wealth These Kaftans with different colors and designs were even more beautiful with their effective combinations and contrast of colors. On the other hand the lower class common people and servants wore simple kaftan with the front part of the kaftan were slipped into the belt in order to be more active and con-venient to work, The real kaftans discovered at Topkapi Saray palace of Turkey from A. D 1300 to 1900 were also compared. These kaftans were very numerous in numbers as well as designs The materials and designs used were also vari-ous such as Chinese to Italian silk. The shaped and pattern itself were not much different from the previous nomad's Kaftans. The Palestian kaftans remained were from the beginning of 19th and 20th century. Since this area is hot and dry desert they used black and navy blue colors mostly in order to exclude the sun lights. The patterns used were similar to Nomads and Bedouin with cross stiches and patch work decorations. In the central Asia they had similar life style and natural environmental cnditions with Turkish tribe which resulted in similar kaftan styles as nomads. Mongols conserved basic patterns of kaftan since Cinggis Khan with deep folding in order to keep warm. At last the kaftans studided in this thesis were classified in to four such as half coat long coat jacket and vest style. A pattern used in the Central Asia were zigzag and ani-mal design whereas in the West Asia were floral plant arabesk and circle pattern. As I discussed previously kaftan styles of nomads in the Asia maintained its basic pat-tern throughout the history except slight changes in color gusset sleeve shapes. These slight changes were made according to the need to adapt the need of environmental natu-ral conditions, The reason for aboriginality of kaftan in Asia was its simplicity and con-venience Most interesting fact is that for all these years Mongols are still wearing kaftan in their life ensuring us that they art the preserves of old kaftan. Since this thesis dealt enormous Asian regions I had a limitation of not being able to cover the Far Esatern asian areas such as Korea China and Japan how these kaftans were influenced in their clothing history as well as Eastern and Western culture. This topic along with the studies on materials and designs of patterns of kaftan will be another research project in the future.

  • This study was done to verify validity of nursing diagnoses related to difficulty in respiratory function. First, content validity was examined by an expert group considering the etiology and the signs / symptoms of three nursing diagnoses - ineffective airway clearance, ineffective breathing pattern, impaired gas exchange. Second, clinical validity was examined by comparing the frequencies of the etiologies and signs / symptoms of the three nursing diagnoses in clinical case studies with the results of the content validity. This study was a descriptive study. The sample consisted of 23 experts (professors, head nurses and clinical instructors) who had had a variety of experiences using nursing diagnoses in clinical practice, and 102 case reports done by senior student nurses of the college of nursing of Y-university. These reports were part of their clinical practice in the ICU. The instrument used for this study was a checklist for etiologies and signs and symptoms based on the literature, Doenges and Moorhouse (1988), Kim, McFarland, McLane (1991), Lee Won Hee et al. (1987), Kim Cho Ja et at. (1988). The data was collected over four month period from May 1992 to Aug. 1992. Data were analyzed using frequencies done with the SPSS / PC+ package. The results of this study are summarized as follows : 1. General Characteristics of the Expert Group A bachelor degree was held by 43.5% and a master or doctoral degree by 56.5% of the expert group. The average age of the expert group was 35.3 years. Their average clinical experience was 9.3 years and their average experience in clinical practice was 5.9 years. The general characteristics of the patients showed that there were more women than men, that the age range was from 1 to over 80. Most of their medical diagnoses were diagnoses related to the respiratory. system, circulation or neurologic system, and 50% or more of them had a ventilator with intubation or a tracheostomy. The number of cases for each nursing diagnoses was : · Ineffective airway clearance, 92 cases. · Ineffective breathing pattern, 18 cases. · Impaired gas exchange, 22 cases. 2. The opinion of the expert group as to the classification of the etiology, and signs and symptoms of the three nursing diagnoses was as follows : · In 31.8% of the cases the classification of etiology was clear. · In 22.7%, the classification of signs and symptoms was clear. · In 17.4%, the classification of nursing interventions was clear. 3. In the expert group 80% or mere agreed to ‘dysp-nea’as a common sign and symptom of the three nursing diagnoses. The distinguishing signs and symptoms of (Ineffective airway clearance) were ‘sputum’, ‘cough’, ‘abnormal respiratory sounds : rales’. The distinguishing sings and symptoms of (Ineffective breathing pattern) were ‘tachypnea’, ‘use of accessory muscle of respiration’, ‘orthopnea’ and for (Impaired gas exchange) it was ‘abnormal arterial blood gas’, 4. The distribution of etiology, and signs and symptoms of the three nursing diagnoses was as follows : · There was a high frequency of ‘increased secretion from the bronchus and trachea’ in both the expert group and the case reports as the etiology of ineffective airway clearance. · For the etiologies for ineffective breathing pat-tern, ‘rain’, ‘anxiety’, ‘fear’, ‘obstructions of the tract, ca and bronchus’ had a high ratio in the ex-pert group and ‘decreased expansion of lung’ in the case reports. · For the etiologies for impaired gas exchanges, ‘altered oxygen -carrying capacity of the blood’ and ‘excess accumulation of interstitial fluid in lung’ had a high ratio in the expert group and ‘altered oxygen supply’ in the case reports. · For signs and symptoms for ineffective airway clearance, ‘dyspnea’, ‘altered amount and character of sputum’ were included by 100% of the expert group. ‘Abnormal respiratory. sound(rate, rhonchi)’ were included by a high ratio of the expert group. · For the signs and symptoms for ineffective breathing pattern. ‘dyspnea’, ‘shortness of breath’ were included by 100% of the expert group. In the case reports, ‘dyspnea’ and ‘tachypnea’ were reported as signs and symptoms. · For the sign and symptoms for impaired gas exchange, ‘hypoxia’ and ‘cyanosis’ had a high ratio in the expert group. In the case report, ‘hypercapnia’, ‘hypoxia’ and ‘inability to remove secretions’ were reported as signs and symptoms. In summary, the similarity of the etiologies and signs and symptoms of the three nursing diagnoses related to difficulty in respiratory function makes it difficult to distinguish among them But the clinical validity of three nursing diagnoses was established through this study, and at last one sign and symp-tom was defined for each diagnosis.

  • In effort to conduct comparative study on the caregiving environment of Neonatal Intensive Care Unit(NICU) in both U. S and Korea, this study was been conducted first in the U.S. Purpose : The purpose of this study is to identify the physical environment and direct caregiving practices to lowbirth weight infants in NICU in the US. It also aims to examine the NICU outcome status and behavioral reponses of lowbirth weight infants. Methods : A study design using descriptive and inferential statistics was been conducted through an observational, field method. A sample of 15 preform infants admitted to NICU were recruited for the study. The subjects were those with birth weight between 1,000 gm to 1,500 gm, born at the gestation period of 27 to 33 weeks, and without any chromosomal or other genetic anomalies, major congenital infections, or maternal illness. Thirty minutes observation(three times of ten minutes of continuous observation)of the infant's behavior and physiological status, and an four-hour observation of the physical environment and direct care giving procedures were been conducted on the 3rd and 10th day after birth, and on the day of discharge from the NICU or at 34weeks postconception. The data to be collected were in four areas : the demograghic characteristics of the infants, the physical environment and care giving procedures, the frequency of the infant's designated behavior and physiological response, and NICU outcome variables. A descriptive analysis and Kruskal-Wallis, Pearson r were been applied according to variable characteristics. Results : 1. Mother's mean age was 29.47. The sample consisted of 6 males and 9 females. Mean gestational ages were 29.17 weeks. Mean birth weight was 1236.33g. Mean Apgar scores at one minute were 6.6, and 7.8 at five minutes. 2. The location for the incubator was in the distance from the light, X-ray screens and nursing station, in proximity to side-lamp, telephone and faucet on the third day after birth. The location for the incubator was in the distance from the light and radio on the tenth day and in proximity to nursing station on the day of dischage from the NICU or at 34weeks postconception. 3. Nesting was the most applying aids to the infants. And foot roll, shielding and plastic frame were frequently using by nurses for facilitating well modulated restful posture. 4. There were statistically significant changes in the patterns of physical environment included locating the infant's incubator and bedding, specific aids to self regulation on the 3rd and 10th day after birth, and on the day of discharge from the NICU or at 34weeks postconception. 5. Statistically significant changes were not appeared in the patterns of direct caregiving procedure to the infants included stress inducing or reducing manipulations on the 3rd and 10th day after birth, and on the day of discharge from the NICU or at 34weeks postconception. 6. The stress response of the infants in NICU were significantly reduced as the infants grow older. 7. There were not statistically significant correlation between the physical envronment and the stress responses of the infants in NICU. 8. There were statistically significant correlation between the direct caregiving procedure to the infants and the stress response of the infants in NICU in the second and third observation on the day three. 9. Average weight gain per day from birth to discharge was 38.73g, number of days in the hospital was 42.60, number of days before bottle feeding was 3.6. Postconception age starting bottle feed ing was 31/sup +5/ weeks. Number of days on mechanical ventilator was average 7.64, 11.42 was an average number of days of oxygen need. Conclusion : It, thus, appears that to minimize the sensorymotor stimulation for the low birthweight preterm infant in NICU, manipulation of care giving practices to the babies whatever the stress inducing or reducing procedures, have to be limited in the immediate early stage after birth. And it needed to be reexamine to identify the appropriate and specific physical environment and the patterns of direct caregiving to the low birthweight preform infant as the infants grow older in NICU.

  • The purpose of this study was to measure the degree of gravidas' knowledge of infant care activity, and to identify the factors influencing the difference of gravidas' knowledge. The subjects of this study consisted of 159 gravida visited 2 general hospitals, 2 OB/GY clinics and 2 midwives' clinics in J city for anenatal care. The data were collected from December 1 to 30, J.989. The instrument used for this study was true false type question which was developed by investigator through literature review. Data were analyzed by percentage, mean, t-test and ANOVA on significant difference with SPSS program. The results of this study were, summarized as follow: 1) The degree of gravidas' knowledge of infant care activity was 36.75, the degree of gravidas' know ledge of physical care activicy was 16.70, and the degree of gravidas' knowledge of psychosocial care activity was 20.00. 2) Among the physical care activity knowledge items, the diaper should be changed whenever it is soiled, $\lceil$shortly after feeding is over, bathing is bad$\rfloor$, $\lceil$gently patted or stroked on the back when bubbling$\rfloor$, $\lceil$10 minutes time in bathing is appropriate$\rfloor$, $\lceil$infant is crying whenever he is hungry per 3-4 hours$\rfloor$, and "room humidity controled 60 percent, more or less> were over a' percentage of 80 of right answer. Among the physical care, accivity knowledge items. $\lceil$a reason for burping was the air' he has swallowed will rise to the top of his stomach and be eructated$\rfloor$, $\lceil$burping is advisable after the feeding$\rfloor$, $\lceil$dressing of umbilical area is not necessary$\rfloor$, $\lceil$the thermometer should not be boiled for disinfection$\rfloor$, $\lceil$it is important chat the infant grasp the whole nipple within his mouth$\rfloor$, $\lceil$using alcohol sponge is bad whenever diaper is soiled", and $\lceil$when temperature is taken by the rectal method, infant legs shoud be grasped firmly_! were less than a percentage of 60 of right answer. 3) Among the psychosocial care activity knowledge items, $\lceil$it is nice, mother smile at bady frequently$\rfloor$, $\lceil$it is nice, mother praise a bady frequently$\rfloor$, $\lceil$it is nice, mother express bady's behavior$\rfloor$, $\lceil$talk frequently to the bady, the bady :should not be disturbed while feeding$\rfloor$, $\lceil$it is nice, mother see a baby face to face , $\lceil$it is nice, mother concentrate one's attention on her baby while playing$\rfloor$, $\lceil$it is nice, mother pat one's baby while he is feeding$\rfloor$, $\lceil$it is advisable, the baby is allowed to touch mother's breast while he is feeding$\rfloor$, $\lceil$it is advisable to stop feeding, if the baby protrudes one's tongue or cries while feeding$\rfloor$, $\lceil$baby is able to hear, see and smell$\rfloor$, $\lceil$it is nice, mother Concentrate one's attention on her baby while feeding$\rfloor$, and $\lceil$it is not advisable for mother to scold baby while he is crying out> were over a percentage of 80 of right answer. Among the psychosocial care activity knowledge items, $\lceil$Using' baby talks is bad when mother talks to baby> and $\lceil$it is nice, mother soothes the baby as soon as possible when he is crying I were less than a percentage of 60 of right answer. 4) There was statistically significant relationship between the degree of gravidas' knowledge of infant care activity and the demographic variables of gravida such as the age(p<0.01) and education level(p<0.01). From these results, it may be concluded that gravidas' knowledge of infant care activity is moderate level, and gravidas' knowledge of psychosocial care activity is greater than that of physical care activity. Also prenatal nursing educations should focus on subjects who have lower percentage of right answer in infant care activity knowledge items.dge items.

  • 본 연구에서는 나물용 팥으로 새롭게 개발된 팥 신품종 연두채의 나물로의 이용 가능성을 평가하고 그 추출물에 대한 항산화성분 및 항산화활성을 측정하였다. 발아시간에 따른 싹 및 뿌리의 길이와 나물 수율을 고려해 볼 때 연두채는 120~144시간 발아시키는 것이 바람직할 것으로 생각된다. 발아시간에 따라 수분은 유의적으로 증가하였고 단백질은 유의적으로 약간 증가하였으나 큰 차이를 보이지 않았다. 연두채의 칼슘, 마그네슘 함량은 유의적으로 증가하는 경향을 보였고 칼륨, 나트륨, 알루미늄 함량은 유의적인 차이를 보이지 않았다. 발아시간에 따른 에탄올 추출물의 총 폴리페놀, 플라보노이드 및 탄닌 등 항산화성분의 함량은 발아시간에 따라 유의적인 차이를 보였다. 충주팥, 연두채, 다현녹두 원료곡의 총 폴리페놀 함량은 각각 1.96, 2.68 및 2.02 mg/g이었고 충주팥과 연두채는 144시간(각각 3.33 및 3.47 mg/g)에 높은 함량을 나타내었다. 원료곡의 총 플라보노이드 함량은 발아시간이 증가함에 따라 충주팥과 연두채가 대체적으로 감소하는 경향을 보였다. 원료곡의 총 탄닌 함량은 발아시간이 증가함에 따라 대체적으로 증가하는 경향을 보였고 충주팥은 120시간(0.96 mg/g), 연두채는 144시간(0.85 mg/g), 다현녹두는 120시간(1.62 mg/g)에 높은 함량을 보였다. 원료곡의 DPPH radical 소거활성은 발아시간이 증가함에 따라 충주팥과 연두채는 대체적으로 감소하고 다현녹두는 증가하였다. ABTS radical 소거활성은 각각 4.57, 6.51 및 2.82 mg TE/g이었고 충주팥과 연두채는 발아 초반에 감소하다가 각각 120 및 72시간 이후 증가하였다. 이상의 결과 연두채 싹나물은 다현녹두 나물에 비해 항산화성분 및 활성은 약간 낮으나 수율이 높고 탄닌 등 쓴맛 성분이 낮아 싹나물로의 이용성이 기대된다.

  • 팥의 생리적 기능성을 높일 수 있는 식품가공기술을 개발함으로써 새로운 소비수요를 창출하고자 볶음차를 제조하고 이러한 팥차 제조과정이 팥의 항산화성분 및 항산화활성에 미치는 변화를 살펴본 결과 볶음시간에 따른 팥 품종별 총 polyphenol, flavonoid 및 tannin 등의 항산화성분 함량은 대체적으로 초반에는 약간 감소하였으나 볶음시간이 증가할수록 유의적으로 증가하는 경향을 보였다. 항산화성분 함량은 16분 볶음처리한 절강성이팥이 각각 12.72 mg GAE/g sample, 3.01 mg CE/g sample 및 3.56 mg TAE/g sample로 높은 함량을 보였다. DPPH 및 ABTS radical 소거활성은 대체적으로 초반에는 약간 감소하였으나 볶음시간이 증가할수록 유의적으로 증가하는 경향을 보였다. DPPH radical 소거활성은 14분 볶음처리한 붉은이팥 추출물에서 7.81 mg TE/g sample로 가장 높은 활성을 보이는 것으로 나타났고 ABTS radical 소거활성은 16분 볶은 금실팥과 절강성이팥, 14분 볶은 붉은이팥에서 21.26, 21.24 및 21.10 mg TE/g sample로 높은 활성을 보였다. 탁도는 충주팥, 아라리, 칠보팥, 검구슬, 연금 팥, 금실팥 및 흰이팥은 증가하였고 절강성이팥과 붉은이팥은 감소하는 경향을 보이는 것으로 나타났다. 팥 품종별 볶음차 열수침출액의 총 polyphenol 함량은 12분 볶은 연금팥($26.55{\mu}g$ GAE/100 mL)이 가장 높았고 총 flavonoid 함량은 10분 볶은 흰이팥($15.10{\mu}g$ CE/100 mL), 총 tannin 함량은 10분 볶은 절강성이팥($14.60{\mu}g$ TAE/100 mL)이 가장 높게 나타났다. 팥 볶음차 열수침출액의 DPPH 및 ABTS radical 소거활성은 12분 볶은 연금팥에서 각각 488.72 및 728.25 mg TE/100 mL로 가장 높은 활성을 보였다. 이상의 결과에서 팥을 볶아 차로 제조할 경우 항산화활성이 우수한 볶음 팥차의 제조가 가능할 것으로 생각된다.

  • 목적 : 골스캔에서 신세포암의 골전이 빈도, 호발 부위 및 전이 양상을 알아보고, 신세포암이 있는 신장의 섭취 형태를 분류하여 신세포암 환자에서 골스캔의 부가적 역할을 알아보고자 하였다. 방 법 : 수술과 조직 검사상 신세포암으로 진단된 158명의 골스캔을 후향적으로 분석하였으며 골스캔상 병변은 방사선학적인 검사와 추적 골스캔, 조직 검사 소견을 통하여 골전이를 확인하였다. 골스캔상 전이 병소의 위치는 두개골, 척추, 견관절, 흉골, 늑골, 골반, 사지의 장골등 7개의 해부학적 위치로 나누었고, 각 병변은 열소와 냉소로 분류하였다. 신세포암을 가진 신장은 섭취 형태에 따라 정상, 광자결손병소, 크기가 커져 있으면서 약한 섭취를 보이는 경우 크기가 커져 있으면서 불규칙한 섭취를 보이는 경우, 초승달 모양으로 밀려 있는 경우 그리고 섭취가 증가되어 있는 경우 등 여섯 군으로 분류하였다. 결 과 : 158명의 환자중 20명(12.7%)에서 71개의 골전이 병변을 관찰할 수 있었고 전체 병변의 약 80%는 구간 골격에 위치하였다. 병변중 55개(77.5%)는 열소로, 16개(22.5%)는 냉소로 보였다. 첫 골스캔을 시행하기 전에 신절제술을 받은 20명의 환자를 제외한 138명의 환자중 70명 (50.7%)에서 비정상 신섭취를 관찰할 수 있었으며, 그 중 골전이가 있는 17명(3명은 첫 골스캔 전에 신절제술을 받았음)의 환자중에서는 14명(82.4%)에서 비정상 신섭취를 관찰할 수 있었다. 비정상 신섭취를 보이는 70명중에서 가장 흔한 두 가지 형태는 광자결손병소와 크기가 커져있으면서 약한 섭취를 보이는 경우로 각각 35명(50%)과 17명(24.3%)이었다. 그리고 골의 통증과 병적 골절을 주소로 내원한 4명의 환자에서는 골스캔상 비정상 신섭취와 골의 병소를 관찰함으로써 인식되지 못했던 원발 종양(신세포암)에 대한 정보를 제공할 수 있었다. 결 론 : 골스캔상 신세포암으로부터의 골전이 병소의 양상과 신섭취 형태를 잘 이해함으로써 골전이 병소를 잘 검출할 수 있을 뿐 아니라, 원발 종양에 대한 정보를 제공할 수 있으리라 생각된다.

  • 본 연구에서는 품종별 팥 메탄올 추출물의 항산화성분과 항산화활성을 비교 분석하고자 하였다. 항산화성분으로 총 polyphenol, flavonoid, anthocyanin 및 proanthocyanidin 함량을 측정하였으며, 항산화활성은 ABTS와 DPPH radical 소거활성을 측정하였다. 품종별 팥의 일반성분과 무기성분의 함량은 품종간에 큰차이를 보이지 않았으며, 식이섬유 함량은 품종간에 유의적인 차이를 보였고 특히 칠보팥(14.81%)의 식이섬유 함량이 가장 높게 나타났다. 추출수율은 태광콩과 대풍콩이 각각 38.70 및 34.61%로 높은 추출수율을 보였으며, 칠보팥, 금실팥 및 밀양8호가 각각 20.76, 20.33 및 20.16%로 비교적 높은 수율을 보였고 중부팥이 13.78%로 가장 낮은 수율을 나타내었다. 품종별 팥 추출물의 총 polyphenol 및 flavonoid 함량은 각각 19.00-34.75 및 12.97-28.95 mg/g으로 대조군보다 높은 함량을 보이는 것으로 나타났으며, 특히 밀양6호는 각각 34.75 및 28.95mg/g으로 가장 높은 함량을 보였다. 품종별 팥 추출물의 총 anthocyanin 및 proanthocyanidin 함량은 각각 5.89-23.77 및 1.83-3.29 mg/g으로 나타나 대조군보다 높은 함량을 보였다. 총 tocopherol 함량은 5.71-7.66 mg/100 g으로 나타났으며, 연금팥이 7.66 mg/100 g으로 가장 높은 함량을 보였다. ABTS와 DPPH radical 소거활성은 밀양6호 추출물이 각각 2.44 및 4.46 mg TEAC/mg extract residue로 가장 높은 활성을 보였다. 이상의 결과를 볼 때 국내에서 개발된 팥 품종은 높은 항산화성분과 우수한 항산화활성을 가지는 것으로 나타나 천연항산화제 개발에 이용될 수 있을 것으로 생각한다.
