Temporal increase of SS induces concentrations in various forms of organic matter including BOD, COD, TOC. Consequently, it causes hard to identify sources of water pollution during or after precipitation. The objective of this study is to investigate variations of DOC concentration caused by increase of flow and changes of external factors in river by comparing to SS concentration. In results, monitoring sites (e.g., Banbyeonchen) consisting of hard riverbed showed high correlation between SS and organic matters, except BOD. On the contrary, other sites (e.g., Naesungcheon) where riverbed consists of sand were found in a wide range of annual fluctuation in SS level, whereas these sites showed a narrow range in annual DOC fluctuation. In Gumhogang and Namgang, a lower correlation between SS and other factors was found most likely because of high concentration in organic matter. However, lower annual fluctuation values of DOC were observed in comparison to those of COD and TOC. Similar results were also confirmed in main river sites, Sangju and Mulgeum. In conclusion, DOC concentration is better indicator for monitoring organic matter which cannot be provided by BOD, COD, TOC in the Nakdong river basin.

<로미오와 줄리엣>의 드라마투르기적 분석 및 공연분석 -셰익스피어의 드라마와 오태석의 공연-

이인순 ( In Soon Lee ) 한국연극학회 2010 한국연극학 Vol.0 No.40

Um die Jahrhundertwende des 20. Jahrhunderts besinnt sich Theater als ein Kunstwerk auf seine eigene Realitat, Korper, Raum und Zeit. Die Existenzweise des Theaterkunstwerks ist Auffuhrung. Die Kennzeichen der Auffuhrung ist Transitorik, Unmittelbarkeit und Ereignishaftigkeit. Auffuhrungsanalyse der Theaterwissenschaft als Disziplin wird lange Zeit vernachlassigt, weil Auffuhrung ein Opfer der Zeit ist. Angesichts der Aufuhrungsanalyse muß man eine Invariante zur Verfugung stellen, um einen Gegenstand zu analysieren. Die Inszenierung als asthetischer Gegenstand ist einmalig und unwiederbringlich. Das Buhnengeschehen ist materielle Realitat, die von dem Zuschauer sinnlich - optisch und akustisch - erfahren wird. Die Inszenierung realisiert sich in `drei Buhnengestalten`: `Intendierte Buhnengestalt`, `realen Buhnengestalt` und `vermeinte Buhnengestalt`. Die Auffuhrung konkretisiert sich im Kopf des Zuschauers nicht als eine reale Buhnengestalt, sondern als ein `asthetisches Objekt`, `als Abdruck der Buhnenvorgange`. Der Platz des Auffuhrungsanalytikers ist der des Zuschauers, des Rezipienten. Die asthetische Buhnengestalt ist eine Rekonstruktion der selektiven wahrgenommenden Auffuhrung, die der `realen Buhnengestalt` ahnelt. Diese Rekonstruktion als neue Schopfung des Rezipienten ist "Simulacrum", das der dem Objekt hinzugefugte Intellekt ist. Der Begriff der Auffuhrungsanalyse wird Synonym fur die Interpretation als hermeneutischer Prozeß. Fur die Methode der Auffuhrungsanalyse gibt es Strukturanalyse und Transformationsanalyse. Strukturanalyse geht ausschließlich von der Auffuhrung aus. Transformationsanalyse geht von der Transformation des Textes aus. Fur diese Arbeit steht dramaturgische Analyse von Shakespeares Romeo und Julia als erste Grundlage. Die Handlungsentwicklung von Romeo und Julia ist klar in `funf Akte` eingeteilt, die insgesamt aus 24 Szenen bestehen. Die Gesamthandlung von Romeo und Julia baut sich pyramidenformig nach dem Schema der steigenden und fallenden Handlung auf: Exposition/ Ausgangssituation (bis zur ersten Begegnung des Liebespaares auf dem Fest), erregendes Moment als Steigerung (von der Verliebtheit bis zur Eheschließung), Wendepunkt/ Peripetie (Mercutios Tod), retardierendes Moment (Julias Scheintod) und Katastrophe (Vereinigung im Grabe). Die Handlung des Stuckes gliedert sich in eine Haupt- und eine Nebenhandlung: dominierend ist die Liebeshandlung zwischen Romeo und Julia, daneben steht die Entwicklung der Fehde zwischen den Familien von Montague und Capulet; sie sind `sich gegenseitig bedingend, steigernd, hemmend und vernichtend`. Parallelisierung und Kontrast der Figurenkonstellation werden in den jeweils sozial oder im Alter entsprechenden Figuren aus den beiden verfeindeten Familien gezeigt. Die Thematik des Stuckes kommt in dem Oxymoron "loving hate" (I.1.175) zum Ausdruck. Shakespeare lasst die Liebeshandlung von Romeo und Julia in der Art der de casibus-Tragodie spielen; deren Handlungsmuster ist `dargestellt im Rad der Fortuna, das einen Menschen emportragt und wieder absturzen lasst`. Das Stuck Romeo und Julia ist eine experimentelle Tragodie. Es beginnt als Komodie mit Zugen einer Romanze, die sich aus dem Motiv der privaten Liebe und Heirat entwickelt. Pater Lorenzo und die Amme treten mit Lorenzos Wissen von der magischen Kraft der Krauter und der Geschwatzigkeit der Amme haufig in der Komodie auf. Die Handlung von Romeo und Julia erreicht mit Mercutios Tod den Wendepunkt, der die komische Welt zur tragischen umwandelt. Fur die Sprache gibt es Prosa der Diener wie die Alltagssprache der einfachen Leute und zugleich Verse der Adeligen. Shakespeare verwendet eine kontrastreiche Metaphorik fur Raum und Zeit. Dreimal geschehen am Tag die Kampfe der verfeindeten Familien auf den offentlichen Platzen. Der Tag wirft ein Licht auf den Hass und die Gewalt. Die Nacht aber ist die Sphare der Liebe, wo Romeo und Julia ihre heimliche Verbindung verborgen halten konnen. Die Liebenden treffen sich in der Nacht und in dem ummauerten Raum. Oh, Tae-Suks "Romeo und Julia" wird in der Form des Madangguks gestaltet. Die Handlung in Oh, Tae- Suks Textfassung ist also nicht nach dem Prinzip der Kausalitat und Folgerichtigkeit zu lesen wie im Shakespeare-Drama. Wegen dem Ignorieren der Kausalitat des Handlungsablaufes und dem Fehlen der Motivation der Handlung ergibt sich hier keine individuelle psychologische Figurencharakterisierung. Die Figuren sind typisiert. Die koreanische Textfassung mit den extremen textlichen Verkurzungen und den zwei szenischen Hinzufugungen pragt die Inszenierung dahingehend, dass an die Stelle der Wortsprache mehr Korpersprache und szenische Bilder treten. Die langen Sprechpartien der Figuren im Shakespeare-Drama werden meistens gekurzt und beschranken sich entweder auf Informationen uber die Situation oder zur Handlungsentwicklung. Und der Handlungsablauf erfolgt in Episoden sowie Musik, Lied und Tanz; Musik, Lied und Tanz dienen einerseits dem Ubergang der Szenen, sind aber andererseits auch selbst Teil des Handlungsablaufs. Wahrend Shakespeare die Sprache der Worter in den Vordergrund ruckt, stutzt Oh, Tae-Suk sich mehr auf die Sprache des Korpers, die ja zugleich bildhaft ist. Dafur nimmt die Inszenierung Tanz und Lieder. Oh, Tae-Suks Inszenierung entwirft Shakespeares Tragodie in der Form des Madangguks als Spiel und zugleich als erkennentnisorientiertes, nachdenkliches Theater fur den koreanischen Zuschauer, das dem traditionellen koreanischen Theater als Unterhaltungstheater nicht moglich ist, in dem sich das Volk von der Wirklichkeit erleichterte und sich vergnugte. Oh, Tae-Suk formt das Publikum zum `Wir` und zugleich zum `Ich`. Mit dem Zusammensein der vollig andernen Theaterkulturen schafft der Reigisseur das hybride Theater und dadurch bildet fur die moderne koreanische Gesellschaft eine neue kulturelle Identitat heraus.

The present study was intended to provide the fundamental data, available in the field of the elderly health care, from the analysis of the actual conditions of pains among the el r)y in terms of their sociodemographic and life styles. The interviews, performed during the two-month period from June to July of 2000, included 635 individuals aged over 65 who live in Daejeon metropolitan city and contained information about the nature, location, severity, and frequency of their pains. The collected data were statistically processed using SPSSWIN(ver 10.0) according to the subjects` sociodemographic, psychological factors and various life styles. 1. In terms of subjective perception of pain, 76.9% of subjects had pain. Significantly higher pain rate of 86.3% were noticed in women than 64.7% in men (p=0.000), but significant difference was not found among age groups. According to the living conditions, pain rates were 88.4% in older persons living alone, followed in a decreasing order of frequency by 73.9% in those living at their homes, and 72.1% in those in nursing homes, with significant statistical difference (p=0.001). Higher level of education was related with significantly lower rate of pain(p=0.000) and significantly higher rate was found in those without spouses(82.8%) than with spouses(68.2.%) in terms of spouse status(p=0.000). 2. Based on classifications of pain severity, 31.8%, the most frequent, were mild and it was followed in a decreasing order of frequency by 29.7% f certain pain, 25.2% of severe pain, 11.3% of very severe pain, and 2.0% unbearable pain. The pain perception was more severe in women than in men, older aged groups than in younger ones, those living alone and in nursing homes than in those living at their homes. Greater severity was also found in those with lower level of education and without spouses than in their respective counterparts. 3. Based on psychological factors, greater severity was found in the groups who are dissatisfied with the present life situation, who have weak-willed in life, who have sense of isolation, and who have considered themselves as unhealthy than in their respective counterparts. On the basis of various life styles, greater severity was also revealed in the groups who don`t have go-outs, who smoke, who don`t drink, don`t exercise, and who are obese than in their respective counterparts. 4. Based on location of pain, greater severity was reported in the back, lower e extremities, and multiple sites than elsewhere. 5. Based on the subjective nature of pain, the 29.9%, the most frequent, of subjects described their pain as “pulling”, 26.0% “tingling”, 24.0% “heavy”, and 20.1% “throbbing”, with sexual difference. 6. The group who reported more severe pain had the higher rate of access to medical service and also had the higher rate of demand for medical service than the group who did not.

This study was intended to find out the factors affecting to the IADL, allowing objective assessment of physical function status of increasing elderly populations. The subjects of 635 elderly persons aged over 65 years old who live in Taejon metropolitan city were interviewed during the two-month period from June to July of 2000. The IADL of Older American Resources and Services(OARS), developed in Duke medical college of USA, was interpreted for use. The study results were statistically processed using SPSSWIN(ver 10.0) and conferred the following results: 1. Among the seven items of IADL, the women showed higher rates of 'yes' in items about using the telephone, getting to the places out of walking distance, going shopping for groceries, taking their own medicine while outnumbered by the men only in the item about managing their own money, without significant differences between them in items about preparing their own meals and doing their own housework. 2. In terms of IADL scores, $82.0\%$ of subjects showed the normal range of scores and $18.0\%$ were under the normal range, meaning dysfunction IADL. Specifications of general characteristics revealed that more dysfunctional were the male subjects, the higher age groups who are more than 75 years old, the higher educated groups, the groups who live in nursing homes, the groups without a spouse. 3. Based on daily activities, lower scores of IADL were found in the subjects who don't go out, who don't have recreational activities, who don't attend elderly gatherings in their neighborhood, who don't hold social meetings. Specifications of psychological traits revealed that more dysfunctional were IADL in the subjects who don't feel satisfied with their lives of the past or the present, who have a deep feeling of isolation, and who don't have the will to live. 4. Among 7 items of health habits, only the subjects who don't regular exercise had lower scores of IADL than those who do. According to HPI, the lower HPI, the more dysfunctional. 5. Based on the factors associated with IADL, the odds ratio of the subjects who don't live together with their families were 1.53 times that of the ones who do, who are educated 3.22 times that of the ones who are not, who don't have spouses 2.09 times that of the ones who do, who don't go out 4.35 times that of the ones who frequently go out, who don't recreational activities for an interest 2.64 times that of the ones who do, who don't attend elderly gatherings in their neighborhood 1.47 times that of the ones who do, who don't hold social meetings 2.23 times that of the ones who do, who don't feel satisfied with their present living 1.43 times that of the ones who do, who have a feeling of isolation 1.53times that of the ones who don'1, who have the weak will to live 3.21 times that of the ones who have the strong one, and who don't regular exercise 2.45 times that of the ones who do. 6. Logistic regression analysis of the study results found that such factors are significantly related as the degree of education, with/without spouse, social meetings, the will to live, and regular exercise, and that higher rates of dysfunctional subjects were in the more educated group, in the group without spouse, in the group who don't frequently go out, who don't have social meetings, who have the weak will to live, and who don't exercise.

Background : A study comparing unit dose drug distribution system(UDS) versus traditional drug distribution system(TDS) was conducted in Seoul National University Hospital. The objectives of this study were to identify safer drug distribution system and to measure the efficiency of both systems in utilizing nursing and pharmacist's time. Methods : The study was designed to compare the data on medication errors, nursing time and pharmacists' time before and after implementation of the UDS in the internal medicine and otorhinolaryngology care units. The data on actual medications administered to patients were obtained by a disguised observer during the study period. The data collected were then compared with the physicians' orders to determine the rate of medication errors. In addition, using ten-minute interval work-sampling method nursing and pharmacists' time were measured. Results : About 6% of medications were administered incorrectly in the TDS, in comparison to 1.6% in the UDS. The rate of medication error decreased significantly in the UDS compared with the TDS. Mean times spent on medication-related activities by nurses were 34.1% in the TDS and 28.5% in the UDS. In the internal medicine care unit, nursing time associated with medications decreased significantly after the implementation of the UDS, but the reduction in medication-related nursing time in the otorhinolaryngology care unit was not significant. Pharmacist's medication-related work activities, increased from 2% in the TDS to 20% in the UDS. Pharmacist's time spent on therapy-related activities increased significantly. Conclusion : The rate of medication errors in the UDS decreased significantly compared with the TDS. Time spent on medication-related activities decreased for nurses while it increased for pharmacists. In summary, the UDS was estimated to be safer and to utilize of pharmacists' and nursing time more efficiently than the TDS.

이인용(In-Yong Lee),박용석(Yong Seog Park),김성민(Sung Min Kim),강철아(Cheol Ah Kang),전병철(Byeong Chul Chun),박재읍(Jae-Eup Park) 韓國雜草學會 2010 Weed&Turfgrass Science Vol.30 No.4

비선택성 제초제인 글루포시네이트암모늄액제를 농작업자의 오판에 의한 오용으로 사과나무에 직접 살포된 경우 품종별, 수령별로 나타나는 약해반응과 수확에 미치는 영향을 조사하였다. 사과나무 품종에 따라 약해정도가 다르게 나타났다. 약제살포 당해연도에는 산사 > 쓰가루 > 홍로 > 후지 순으로, 약제살포 다음해에는 후지 > 쓰가루 > 홍로 > 산사 순으로 피해가 나타났으나, 그 피해정도는 당년에 비해 경미하였다. 이듬해, 후지에서는 꽃과 착과정도에서만 30%정도 감소하였으나 쓰가루, 홍로, 산사에서는 개화상태, 착과율 등에서 전혀 피해증상이 관찰되지 않았다. 약해를 받은 당년에 조생종 쓰가루와 중만생종후지 대상으로 각각 수확기 10일전에 사과 중 잔류량을 검사한 결과, 잔류량은 검출한계(0.04ppm) 미만이었다. 그리고 오용 2년 후(2009년)에는 후지, 쓰가루, 홍로, 산사 모두에서 약해증상이 나타나지 않았다. This study was conducted to investigate the phytotoxic reaction and the impact on the growth of apple fruit included the yield amount by misuse of non-selective herbicide, glufosinate-ammonium in apple field and for the study, 4 cultivars of apple were tested. The results showed that the highest phytotoxic degree was observed on Sansa-cultivar and then the degree was diminished on Tsugaru, Hongro and Fuji in order in the application year. In one year after application, the highest phytotoxic degree was showed on Fuji and then diminished on Tsugaru, Hongro and Sansa in order. However, in one year after application, the phytotoxic symptom was negligible in comparison with the degree in the year of application and the flowering and fruiting were reduced 30% only in Fuji, but in the other cultivars, the phytotoxic symptoms were not observed. Meanwhile, the residue of glufosinate-ammonium was below the detection limit as 0.04ppm in all tested cultivars and in 2years after application, the phytotoxic symptom was not observed in all cultivars of the apple.

북한의 시장화와 가족윤리의 변화

이인정 ( Lee In-jeong ) 한국윤리교육학회 2019 윤리교육연구 Vol.0 No.51

북한이 경험한 사회주의 고난의 행군과 사적 경제 활동의 증가로 오늘날 북한에는 400여 개 이상의 공식시장이 생겨났다. 북한의 시장화는 주민생활과 가치관에 있어서 다양한 변화를 초래하는 배경이 되고 있다. 시장의 확산과 함께 새 세대 청년들의 개방화와 물질주의적 경향이 늘어나고 결혼과 가족윤리에 있어서도 변화가 생기고 있다. 북한의 부부 및 친족 윤리에 있어서 기존 관습과 성역할에 대한 비판적 성찰이 생겨나고, 가사와 자녀 교육에 있어서 분담 의식도 늘어나고 있다. 북한 사회에도 저출산 경향과 소자녀관 추세가 확대되면서, 인구문제에 대한 당국의 관심 역시 늘어나고 있다. 이중적 가치의 양상을 보이면서 생겨나고 있는 북한의 변화는 남북 주민 간 상호 유사성을 높이는 긍정적 측면도 존재한다. Due to the March of Socialist Suffering experienced by North Korea and the increase in private economic activities, more than 400 official markets have emerged in North Korea today. The marketization of North Korea has become a background that causes various changes in the lives and values of residents. With the spread of the market, there has been an increase in the openness and materialist tendencies of new generation young people in North Korea and changes in marriage and family ethics. In the ethics of married couples and relatives in North Korea, critical reflection on existing customs and gender roles is being created, and awareness of sharing of household chores and child education is also increasing. North Korean society is also expanding with the tendency of low birth rate, and North Korean authorities' interest in population issues is also increasing. The change in North Korea that is emerging in the aspects of dual values has positive aspects that enhance the similarity between the two Koreas.

대전지역에서 호밀과 헤어리베치의 파종유형별 사초의 건물수량 및 사료가치 비교연구

이인덕(In Duk Lee),이형석(Hyung Suk Lee) 한국초지조사료학회 2006 한국초지조사료학회지 Vol.26 No.4

본 시험은 2002년 9월부터 2004년 12월까지 충남대학교 농업생명과학대학 내 부속 초지시험포장에서 수행하였다. 공시초종은 청예용 호밀(Koolgrazer)과 헤어리베치(Common)를 공시하여 주구로 호밀 단파, 호밀 80% + 헤어리베치 20% 혼파, 호밀 60% + 헤어리베치 40% 혼파 및 헤어리베치 단파 등의 4 파종유형과 세구로 수잉기, 출수기, 개화기 및 유숙기 등의 4수확시기를 두어 분할구배치법 3반복으로 시험하였으며, 얻어진 결과는 다음과 같다. 2년 평균 ha당 건물수량은 파종유형과 수확시기에 따라 차이를 보여, 호밀 단파구(9,776㎏)가 호밀 80% + 헤어리베치 20% 혼파구(9,045㎏)나 호밀 60% + 헤어리베치 40% 혼파구(8,272㎏) 및 헤어리베치 단파구(5,424㎏)에 비하여 높은 결과를 나타내었고, 모든 처리구에서 수확시기가 진행됨에 따라 유의적으로 증가되었다(p<0.01). 화학적 성분도 파종유형과 수확시기에 따라 차이를 보여, CP 함량과 DMD는 헤어리베치 단파구에서 높았던 반면에 섬유소물질의 함량은 가장 낮았으나, 호밀 단파구에서는 상반되는 결과를 보였다(p<0.01). 조단백질수량(CPDM)과 가소화건물(DDM) 수량은 호밀 80% + 헤어리베치 20% 혼파하여 개화기~유숙기에 수확하는 것이 가장 높았다(p<0.01). 이상의 결과로 보아, 호밀이나 헤어리베치의 단파 이용보다는 호밀에 헤어리베치를 20% 정도 혼파하여 개화기~유숙기에 수확하는 것이 단위 면적당 수량과 사료가치를 높일 수 있는 한가지 방법이라 하겠다. The object of this experiment was to suggest the optimum utilization upon rye and hairy vetch crops in Daejon area. The field trials were conducted from 2002 to 2004 at Chungnam National University in order to evaluate the dry matter yield and quality of rye, hairy vetch, and rye + hairy vetch mixtures. The experiment was designed with split plots (main plot : seeding rate as rye mono culture, hairy vetch monoculture, rye 80%+hairy vetch 20%, rye 60%+hairy vetch 40%, and sub plot : 4 cutting stages as boot, heading, anthesis, milk). The average DM yield for 2 years had a difference on seeding rate and harvesting stages. The DM yield of rye monoculture was higher than those of the other seeding rates. There were significant increases in advanced stages in all treatments. In chemical composition, they also had a difference on seeding rates and growth stages. Hairy vetch monoculture was higher in crude protein (CP) and dry matter digestibility (DMD), but lower in fibrous compound than those of the other seeding rates (p<0.01). The crude protein dry matter (CPDM) and digestible dry matter yield was higher in rye 80% + hairy vetch 20% mixture when it was harvested at anthesis to milk stages. The results of this experiment indicated that when it was harvested at anthesis to the milk stages, rye 80% + hairy vetch 20% mixture was more effective in enhancing the DM yield and forage quality in Daejon area.

이인덕(In Duk Lee),이형석(Hyung Suk Lee) 韓國草地學會 2007 한국초지조사료학회지 Vol.27 No.2

The object of this experiment was to investigate the effect of mixture which consist of different seeding rates and species on dry matter yield and quality in Daejon area. The field trials were conducted from 2003 to 2005 at Chungnam National University in order to evaluate the dry matter yield and quality of different mixture. The experimental design includes three mixture types: Conventional mixtures, CM{orchardgrass(Potomac) 50% + tall fescue (Fawn)20% + Kentucky bluegrass(Kenblue) 20% + white clover (Regal) 10%}, red clover+mixtures, RM{orchardgrass(Potomac) 40% + tall fescue(Fawn) 20% + Kentucky bluegrass(Kenblue) 10% + red clover(Kenland) 30%} and Turf type grass +mixtures, TM {orchardgrass (Potomac) 50% + turf type grass (tall fescue, Millennium 20% + Kentucky bluegrass, Midnight 10% + perennial ryegrass, Palmer Ⅲ 10%) + white clover(Regal) 10%}. The average DM yield for 2 years of red clover+mixture(11,656㎏/ha) was higher than those of the other mixtures(p<0.05). The content of crude protein and dry matter digestibility were higher in red clover+mixture than in other mixtures(p<0.05). but, the content of fibrous compounds like as NDF, ADF, cellulose and lignin were lower in red clover+mixture than in other mixtures(p<0.05). The crude protein dry matter(CPDM) yield was higher in red clover + mixture(2,832㎏/ha) than in conventional mixture(2,372㎏/ha) and turf type + mixture(2,266㎏/ha)(p<0.05). The digestible dry matter (DDM) yield was higher in red clover + mixture(8,881㎏/ha) than in conventional mixture(8,255㎏/ha) and turf type + mixture(7,314㎏/ha)(p<0.05). In botanical composition at last cutting time in 2005, conventional mixture were maintained orchardgrass 45%, tall fescue 22%, Kentucky bluegrass 5% and white clover 24%. Red clover + mixture were maintained orchardgrass 40%, tall fescue 22%, Kentucky bluegrass 4% and red clover 31%. turf type + mixture were orchardgrass 37%, tall fescue 23%, Kentucky bluegrass 6%, perennial ryegrass 8% and white clover 24%, respectively. As summary, DM yields and quality of mixture species and seeding rates were observed significant difference. The results of this experiment indicated that red clover + mixture was more effective in enhancing the DM yield and forage quality in Daejon area. 본 연구는 초종과 파종비율을 달리한 혼파초지를 비교 검토하여 건물수량과 품질을 높일수 있는 혼파방법을 찾고자 관행 혼파초지{Conventional mixtures(CM), orchardgrass (Potomac) 50% + tall fescue (Fawn)20% + Kentucky bluegrass(Kenblue) 20% + white clover(Regal) 10%}, 레드 클로버 + 혼파초지{Red clover mixtures(RM), orchardgrass (Potomac) 40% + tall fescue 20%(Fawn) + Kentucky bluegrass(Kenblue) 10% + red clover(Kenland) 30%} 및 잔디형 초종 + 혼파초지{Turf type grass mixtures(TM), orchardgrass (Potomac) 50% + turf type grass(tall fescue, Millenium 20% + Kentucky bluegrass, Midnight 10% + perennial ryegrass, Palmer Ⅲ 10%) + white clover, Regal 10%)의 3처리를 두어 시험하였다. 시험은 난괴법 4반복으로 충남대학교 농과대학 초지시험포장에서 2003년 9월부터 2005년 12월까지 수행하였으며, 시험결과는 다음과 같다. 2년 평균 건물수량은 레드 클로버 + 혼파초지가 11,656㎏/ha으로 관행 혼파초지(11,245㎏/ha)나 잔디형초종 + 혼파초지(9,897㎏/ha)에 비하여 높은 결과를 가져왔다(p<0.05). CP 함량은 연도와 혼파초지의 유형에 관계없이 레드 클로버 + 혼파초지가 관행 혼파초지나 잔디형 초종 + 혼파초지에 비하여 높은 결과를 보였다(p<0.05). NDF, ADF, cellulose 및 lignin과 같은 섬유소물질의 함량은 조사연도와 혼파초지의 유형에 따라 대체적으로 레드 클로버 + 혼파초지가 관행 혼파초지나 잔디형 초종 + 혼파초지에 비하여 낮은 결과를 보였다(p<0.05). 2년 평균 DMD는 레드클로버 + 혼파초지가 76.2%으로 관행 혼파초지(73.4%)나 잔디형 초종 + 혼파초지(73.9%)에 비하여 높은 결과를 보였다(p<0.05) 2년 평균 CPDM 수량은 레드 클로버 + 혼파초지가 2,832㎏으로 관행 혼파초지(2,372㎏)나 잔디형초종 + 혼파초지(2,266kg)에 비하여 높은 결과를 나타내었다(p<0.05). 2년 평균 DDM 수량은 레드 클로버 + 혼파초지가 8,881㎏으로 관행혼파초지(8,255㎏)나 잔디형 초종 + 혼파초지(7,314㎏)에 비하여 높은 결과를 얻었다(p<0.05). 2005년 5회 예취시의 식생비율은 관행 혼파초지는 orchardgrass는 45%, tall fescue 22%, Kentucky bluegrass 5% 및 white clover 24%이었으며, 레드 클로버 + 혼파초지는 orchardgrass 40%, tall fescue 22%, Kentucky bluegrass 4% 및 red clover 31%이었고, 잔디형 초종 + 혼파초지는 orchardgrass 37%, 잔디형 초종 37%(tall fescue 23%, Kentucky bluegrass 6%, perennial ryegrass 8%) 및 white clover 23%를 유지하였다. 이상의 결과를 종합할 때, 초종과 파종비율에 따른 혼파초지의 건물수량과 사료가치의 차이를 확인할 수 있었으며, 레드 클로버 + 혼파초지가 건물수량과 사료가치를 높이는데 효과적이었다.

사과, 배, 복숭아, 포도 등을 재배하는 과수원에 발생하는 잡초를 조사하여 과수원 문제잡초의 현황을 파악하고 잡초방제의 기초자료로 활용하기 위하여 2015년에 전국을 11개 권역으로 나누어 실시하였다. 과수원에 발생하는 잡초는 63과 492종으로 국화과 86종, 화본과 63종, 두과 29종, 사초과 23종, 마디풀과 22종 등의 순이었다. 이들 잡초를 생활형으로 구분하면, 일년생 159종, 동계 일년생 97종, 다년생 236종이었다. 과수원별 발생잡초를 보면, 사과밭에는 50과 306종, 배밭에는 50과 304종, 포도밭에는 50과 286종, 복숭아밭에는 48과 288종이 발생되었다. 우점잡초로는 바랭이, 쑥, 쇠별꽃, 닭의장풀, 깨풀 등이었다. 외래잡초는 127종으로 전체의 25.8%이었고, 토끼풀, 망초, 흰명아주, 서양민들레, 소리쟁이 순으로 발생이 많았다. 30년간의 잡초군락 변화를 보면, 1990년에는 바랭이, 여뀌, 쇠비름 등이 우점하였으나, 2003년에는 바랭이, 깨풀, 쑥 등으로 변하였다. 2015년에는 바랭이, 쑥, 쇠별꽃 등으로 크게 변하지는 않았다. This study was investigated in order to occurrence of weed flora in orchard (apple, grape, peach, pear etc.) fields and to the establishment of weed control basic data in these weeds. And this study was survey on 2015. As a result of the study on orchard weeds, there were total of 492 weeds including 63 families. Among all the weeds, 159 species were annual, 97 species were winter annual and 236 were perennial. Each fruit tree patterns of occurrence weeds, 306 species 50 families in apple orchard, 304 species 50 families in pear orchard, 286 species 50 families in grape orchard, and 288 species 48 families in peach orchard. Dominance was the highest with Digitaria ciliaris followed by Artemisia princeps, Stellaria aquatica, Commelina communis, Acalypha australis etc. in order. And exotics weeds occurred 127 species. Trifolium repens was the highest in importance analysis and the followings were in order of Conyza canadensis, Chenopodium album, Taraxacum offcinale, Rumex crispus etc. Changes in weed vegetation in orchard during 30 years, did not very many changed. In 1990, D. ciliaris, Persicaria hydropiper, Portulaca loeracea were dominant. In 2003, D. ciliaris was the most abundant species, followed by A. australis, A. princeps species. And in 2015, also D. ciliaris was the most dominant, followed by A. princeps, S. aquatica.
