본 硏究는 養液栽培時 養液濃度와 培地種類가 대립계 포도품종인 Black Olympia의 生育과 果實品質에 미치는 영향을 구명하고자 하였다. 新梢長은 0.5배에서 1.5배의 양액농도에서 농도가 높을수록 길었고, 배지종류별로는 0.5배 농도에서는 밭흙과 퇴비를 1:1로 혼합한 배지에서 신초장이 길었으나 1.5배 농도에서는 오히려 짧게 나타났다. 節間長은 저농도의 양액농도에서는 밭흙과 퇴비를 혼합한 배지가 길었으나 1.5배의 고농도에서는 차이를 보이지 않았다. 각 배지에서 濃度가 높을수록 간경이 크게 나타났으며 배지종류간에는 펄라이트와 버미큘라이트 혼합배지가 밭흙과 퇴비를 혼합한 배지보다 컸으나 유의차가 없었다. 果房重은 각 배지에서 1.0배의 양액농도가 가장 무거웠으며 배지 종류간에는 밭흙과 퇴비를 혼합한 배지가 더 무거웠다. 糖度는 각 배지의 1.0배 양액농도가 높았으며 배지종류간에는 차이를 보이지 않았다. 果皮의 안토시아닌 함량은 배지별로 밭흙과 퇴비를 혼합한 배지에서 높았으며 양액농도별로는 1.0배에서 높게 나타났다. 收量은 펄라이트와 버미큘라이트를 혼합한 배지에서 양액농도가 높을수록 많았으나 밭흙과 퇴비 혼합배지에서는 1.0배의 농도에서 높게 나타났다. This study was carried out to investigate the effects of ionic strength and substrates on growth and fruit quality, and to establish fruit tree nutrient solution culture. The higher ionic strength showed the longer shoot length of grape. Among the substrates, upland soil+compost showed longer shoot length than perlite+vermiculite in 0.5 strength but shorter in 1.5 strength of Hoagland solution. Internode length was longer in upland soil+compost than in perlite+vermiculite in 0.5 strength, but there were no significance in 1.0 and 1.5 strength of Hoagland solution. Higher ionic strength and/or perlite+vermiculite of substrates showed tricker in trunk diameter than lower ionic strength and/or upland soil+compost. Cluster weight was heavier in 1.0 ionic strength than the others. Cluster weight in upland soil+compost was heavier than that of perlite+vermiculite. Soluble solids content of berry was the highest as much as 17.3。 Bx on 1.0 ionic strength of three strength, but there are no significances in substrates. Anthocyanin content of grape skin was higher in upland soil+compost than perlite+vermiculite, as well as the highest in 1.0 strength among three strengths. The higher ionic strength showed the more berry set. Each substrate showed uniformal berry set and growth. The best result in berry yields was obtained in 1.0 ionic strength with substrate of upland soil+compost in comparison to other treatments.

복숭아나무 경지삽목 번식에 있어서 삽수 굵기와 길이 및 삽수내 저장 양분 함량이 발근과 포장활착에 미치는 영향을 구명하였다. 삽수 굵기는 直徑 5∼8㎜의 삽수가 발근율이나 발근수, 발근장 등 뿌리 발달이 좋았으나 포장 활착율은 삽수재 저장양분이 많은 직경 8∼11㎜가 좋았다. 삽수 길이는 20∼30㎝ 처리가 발근율, 발근수, 발근장 등 발근력이 좋았으나 포장 활착율은 삽수재 잔존 저장 양분이 많은 30㎝ 길이가 좋았다. 삽목용 적정삽수는 8㎜ 굵기에 30㎝ 길이가 가장 효과적이었으며 포장에서 활착후 묘고, 간경 등 생육은 모든 처리에서 116㎝ 이상, 20.4㎜ 이상으로 삽목 당년에 우량묘가 생산되었다. This experiment was studied to examine the effect of cutting size and storage nutrient on rooting and survival in field using hardwood cutting of 'Sunaga Wase' peach to establish mass production system of rooted cutting. Cuttings having 5 to 8㎜ in stem diameter showed the best rooting percentage, root number and root length. In the survival in field, the stem diameter of 8 to 11㎜ showed the highest survival rate and less consumption of storage nutrient during cutting. Those hardwood cuttings of 20 to 30㎝ in stem length showed the best rooting, and higher survival in field was obtained in 30㎝ long cuttings. After transplanting rooted cuttings to field, tree height and trunk diameter of 'Sunaga Wase' peach was 116㎝ and 20.4㎜, respectively.

본 실험은 스프레이 국화 왕겨 배지를 이용한 순환식 양액재배에 있어서 양액의 적정농도와 공급횟수를 구명하고자 실시한 결과 양액 농도 처리에서는 원시표준액의 1.6배 처리구가 초장, 화경장, 경경, 화경수, 엽장, 엽폭, 절화중에서 가장 양호하였고, 1일 공급횟수는 표준농도(1.0배)는 12회가 좋았고 1.3배와1.6배 처리구에서는 6회공급구에서 절화품질이 좋았다. 양액농도별 개화기는 표준농도에 비해 1.3배는 2일, 1.6배 처리구는 3일정도 지연되었다. 양액 농도별 T-N함량은 1.3배 농도에서 많았고 양이온치환용량은 농도가 높은 1.6배 농도에서 높았으며 양액 농도별 엽록소 함량은 1.0배 농도에서 가장 높았다. This experiment was conducted to determine the optimal ionic strength of nutrient solution and fertigation frequency affecting growth and development of spray chrysanthemum (Dendranthema grandiflorum) in recycling system using rice hull. Growth parameters in terms of plant height, flowers diameter, stem diameter, number of flowers, leaf length and width and flower weight were shown better in thd 1.6 ionic strength of nutrient solution than those of 1.0 ionic strength of nutrient solution. Fertigation frequency was good at 12 times during day and night in the standard solution (1.0 ionic strength) while 6 times per day and night were good in both 1.3 and 1.6 strength of nutrient solution. Flowering time was postponed up to 2 day in the treatment of 1.3 ionic strength of nutrient solution, and 3 day in 1.6 ionic strength of nutrient solution. The content of total nitrogen was higher in the 1.3 ionic strength of nutrient solution. Cation exchange capacity was high in the 1.6 ionic strength of nutrient solution and chlorophyll content by the concentrations of nutrient solution was highest in the standard nutrient solution.

조생종 포도 Himrod Seedless 품종의 성숙기 탈립을 억제하기 위하여 GA₃과 2,4-D 및 2,4-DP를 단용 및 혼용 처리하였던 바, GA₃ 처리에 의해서 과립 비대가 촉진되었고 2,4-D 및 2,4-DP의 단용처리는 과립비대에 영향을 주지 않았다. 2,4-D 의 단용 및 혼용처리는 과립의 가용성 고형물 함량을 감소시키고 유기산 함량을 증가시켰으며 당/산비를 저하시켜 품질의 악화를 초래하였을 뿐만 아니라 숙기를 10-15일 정도 지연시켰다. 과립경부의 발육효과에 있어서 GA₃과 2,4-D 및 2,4-DP의 단용처리간에는 GA₃ 처리효과가 가장 우수하였고 다음으로 2,4-D 및 2,4-DP의 혼용처리시 과립경의 발육상태이 매우 양호하였고 BRF도 높아졌으며 cellulase와 PG 활성도가 현저히 감소하였다. 이상의 결과로 보아 포도 Himrod Seedless의 성숙기에 환경적 요인으로 인한 탈립의 우려가 클 경우 GA₃과 2,4-DP의 병행처리가 바람직할 것으로 생각되었다. To investigate the effect of growth regulators to reduce berry abscissions at maturity stage, this study was carried out with dipping berry cluster into 50 and 100ppm GA₃ at full-bloom (FB) + 10 days after FB of Himrod Seedless grapes. Each 5ppm 2,4-D or 40ppm 2,4-DP solution was sprayed to berry at 30 days after FB, respectively. Bigger cluster and berry were obtained by GA₃ treatment, but 2,4-D and 2,4DP treatments did not influence berry enlagement. 2,4-D treatment with or without GA₃ resulted in poor berry quality such as low soluble solid contents, sugar/acid ratio, and high organic acid content, and delayed maturity date up to 10 to 15 days. The best effect was obtained in development of berry stalk by GA₃ treatment, followed by 2,4-D and 2.4-DP treatment. The both treatments of GA₃+ 2,4-D and GA₃+ 2,4-DP resulted in better development of berry stalk higher BRF, and lower cellulase and PG activity. In conclusion, under unfavorable environmental conditions, GA₃+2,4-DP treatment may influence in protecting the berry abscissions of Himrod Seedless grapes.

김수인,연규월,하은희,우행원,김영철 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.3

연구목적 : 최근 산업재해(이하 산재) 및 교통사고 발생이 증가하면서 사고 후유증으로 치료받는 환자들이 늘어나고 있다. 산재를 포함한 각종 사고들은 환자의 신체적 상태를 변화시킬 뿐 아니라 이로 인한 사회적, 직업적, 경제적 문제들을 초래하게 되고 환자의 삶 전체를 변화시킬수 있다. 본 연구에서는 산재가 환자들에게 미치는 정신적 영향을 알아보기 위해 산재 환자들과 대조군에서 삶의 질, 자살사고 및 우울증상을 비교하였다. 방 법 : 연구대상은 1999년 12월 21일부터 12월 30일 사이에 경상남도 울산 마산·창원지역의 입원한 산재환자 169명이었고 정상 대조군은 울산의 공업단지 내 일반근로자 166명이었다. 평가군과 대조군 모두 남성이었고, 19세에서 60세였다. 모든 대상에서 일반 인구학적 특성, 삶의 질, 자살사고, 우울 증상을 평가하였고, 산재 환자군의 경우 사고일시, 사고원인, 치료기간, 손상부위를 추가로 조사하였다. 주관적 삶의 질은 한국판 스미스클라인 비챰 삶의 질척도로 평가하였고, 자살사고는 Beck의 자살사고(思考)척도로 평가하였으며, 우울증상은 PRIME-MD를 개선한 Patient Problem Questionaire의 우울증 척도로 평가하였다. 결 과 : 산재환자군과 대조군간 일반 인구학적 요인에서 통계적으로 유의한 차이 없었다. 산재환자군이 대조군에 비해 유의하게 낮은 삶의 질 척도 점수를 나타냈고, 유의하게 높은 자살사고와 우울증상을 나타냈다(p<.05). 산재환자군에서 연령, 결혼상태, 치료기간과 삶의 질 점수는 관련이 있었다. 30대 이상의 연령에서 유의하게 낮았고 10∼20대 연령에서 유의하게 높았으며, 미혼이거나 이혼, 별거중인 경우 유의하게 삶의 질 점수가 낮았고, 치료기간이 길수록 낮았다. 치료기간과 자살사고가 관련있었으며, 치료기간이 길수록 자살사고가 많았다. 산재환자군에서 손상부위에 따라 삶의 질 점수, 자살사고 점수와 우울증상이 유의한 관련이 있었다. 삶의 질 점수는 요추부 손상군에서 높았고, 경추부 손상군과 다발성 좌상환자군에서 낮았다(p<0.01). 자살사고 점수는 경추부손상군과 다발성 좌상 환자군에서 높았고, 요추부 손상군에서 낮았다(p<0.01). 연구 대상군에서 삶의 질 점수, 자살사고 점수, 우울증상간 유의한 상관관계가 있었다. 결 론 : 본 연구 결과 산재환자들은 일반 근로자들과 비교하였을 때 삶의 질이 낮다고 느끼고 있었으며, 주관적으로 우울감과 자살사고를 많이 나타냈다. 따라서 산재로 인한 우울 및 자살등의 증상을 예방하기 위해서는 조기 정신과적 치료 중재가 반드시 필요하다고 생각된다. Objective : As the occupational and traffic accidents are increased, patients who are treated for complications of accidents have been increased in recent years. Accidents including industrial injury affect the physical state of the patients and make social, vocational, and economic problems, so that they can affect the whole life of the patients. We performed this study to compare subjective evaluation of quality of life, depressive symptoms, and suicide ideation in both industrial injury patients and control subjects in order to know how industrial injury affect patients in psychiatric aspect. Method : The subjects were 169 inpatients who met the inclusion criteria of industrial injury patients and 166 healthy control subjects. All subjects were male and their age is from 19 to 60 years old. Demographic variables, quality of life, depressive symptom, suicide ideation were assessed in subjects. The types of injury and duration of treatment were assessed in patients. The quality of life was measured using the Korean version of SmithKline Beecham 'Quality of Life' Scale(KvSBQOL), and the suicide ideation was measured using the Scale for Suicide Ideation(SSI), and the depressive symptom was measured using the Dpression scale of Patient Problem Questionaire(PPQ) which were devised from Primary Care Evaluation of Mental Disorder(PRIME-MD). Results : 1) There were no significant differences in the general demographic variables between industrial injury patients and control subjects. 2)Scores of KvSBQOL were significantly lower, and SSI and Depression scale of PPQ were significantly higher in the industrial injury patients than control subjects(p<0.05). 3) In industrial injury patients, there was a correlation between the age and the scores of KvSBQOL(p<0.01). The scores of KvSQOL were lowest in older than 30's, highest in 10's-20's. No significant correlation was recognized between the age and the suicide ideation, the depressive symptoms. Threre was a correlation between the marital status and the scores of KvSBQOL(p<0.01). In unmarried, divorced or separated state, the scores of KvSBQOL were significantly lower than married state. There was a correlation between the the duration of treatment and the scores of KvSBQOL, the suicide ideation. As the duration of treatment was longer, the scores of KvSBQOL were significantly lower(p<0.01), and the scores of SSI were significantly higher(p<0.01). 4) In industrial injury patients, there was a significant correlation between the type of injury nd the scores of KvSBQOL, the suicide ideation, and the depressive symptoms. The scores of KvSBQOL were highest in the L-spine injury patients, lowest in the C-spine injury and multiple contusion patients(p<0.01). The scores of SSI were higher in the C-spine injury and multiple contusion patients, lowest in the L-spine injury patients(p<0.01). 5) In subjects, there was significant correlation between the scores of KvSBQOL, the scores of SSI, and the Depression scale of PPQ. Conclusion : Industrial injury patients feel bad about the quality of life and have more depression and suicide ideation. As a results, psychiatric intervention is needed for prevention of depression and suicide due to industrial injury.

식물생장조절제 처리가 Himrod Seedless 포도의 과실품질에 미치는 영향

김월수,김광수 全南大學校 農業科學技術硏究所 1999 農業科學技術硏究 Vol.34 No.-

조생종 포도 Himrod Seedless 품종의 과립을 비대와 과실성숙을 촉진시키기 위하여 만개기, 만개기+만개후 10일, 및 만개기+만개후 10일+20일에 Ga₃ 용액을 각각 1회, 2회 및 3회씩 침지처리하였다. 과립중은 GA₃ 1차 처리에 의하여 현저히 비대가 촉진되었고 처리횟수가 2회 및 3회로 늘어날수록 과립비대도 증가하는 경향을 나타내었다. GA₃ 처리에 의하여 과방경(果房梗)이 현저히 비대되었고 과립 탈립력이 강화되었다. GA₃ 2회 및 3회 처리에 의하여 과립이 크게 비대됨에 따라 과립의 가용성 고형물 함량이 다소 감소되었고 유기산 함량은 차이가 없었다. GA₃, GA₄+7 및 BA 용액을 처리한 결과 과립중과 과방중은 GA₄+7 처리구에서 가장 무거웠으나 가용성 고형물 함량이 낮아서 당산비가 최저수준을 나타내었고 수기도 무처리구보다 6일 정도 지연되었다. 이상의 결과로 보아 포도 Himrod Seedless 품종의 재배는 만개기에 GA₃ 50ppm 용액에 화방침지하고 10일후 제2차로 GA₃ 100ppm 용액에 침지처리하는 것이 착립과 과립비대에 효과적인 것으로 판단되었다. To investigate the effects of berry enlargement and maturity by growth regulators treatment this experiment was carried out by dipping berry cluster into 50 to 100 ppm GA₃, GA₄+7, and benzyladenine (BA) at full-bloom, 10 and/or 20 days after full-bloom of 'Himrod Seedless' grape. Berry weight increased outstandingly by GA₃ treatment, and GA₃ treatment for three times showed more increased berry weight than that twice and once. GA₃ treatment resulted in increased cluster stalk diameter which induced higher berry removal force. However, soluble solid content in berries treated for two to three times with GA₃ decreased due to dilution effect of berry size. Organic acid contents in berries were not influenced by GA₃ treatment. Among the three kinds of plant growth regulators such as GA₃, GA₄+7, and BA, GA₄+7 treatment gave rise to the biggest berry growth, but lower soluble solid content, sugar/acid ratio and delayed maturity upto six days in comparison to control. In conclusion the best result in berry growth and quality could be obtained by dipping the berry cluster into 50ppm GA₃ at full-bloom, and 100ppm GA₃ at 10 days after full-bloom.

복숭아 품종별 경지 삽목에 있어서 삽수기부의 Wounding이 발근 및 활착에 미치는 영향

This experiment was studied to examine the effect of cutting time, mulching materials and soil water contents on field establishment of hardwood cutting of 'Sunaga Wase' peach. The most adequate time for hardwood cutting was found to be from early February to middle February, transplanting on mid to late March showed higher field establishment. Therefore the sooner cutting, the better field establishment. Black and clear-black-stripe polyethylene film showed higher field establishment because mulching materials at transplanting time play a important role to control the changes of soil temperature and moisture contents affecting field establishment.
