본 연구는 기술수용모델을 이용하여 온라인 디지털플랫폼 사용자의 이용의도와 이용행동에 영향을 미치는 요인을 살펴보는 것을 목적으로 하고 있다. 본 연구에서 제시된 연구모델과 가설들에 대한 분석을 하고자 오프라인을 통해서 설문조사를 진행하였다. 이를 기반으로 시각예술전문가의 수용에 대한 디지털플랫폼채택 기술수용모델을 적용한 결과 다음과 같은 결과를 얻게 되었다. 첫 번째 기술숙련도는 태도와 이용의도에 영향을 미치는 것으로 나타났다. 두 번째 인지된 유용성은 태도에 영향을 미치는 것으로 나타났다. 사용하면 얻을 수 있는 가치들이 사용자들에게 인지가 되면 디지털플랫폼에 접속하는 것에 대해서 긍정적인 태도를 보이게 될 것으로 판단된다. 세 번째 인지된용이성은 태도에 영향을 미치는 것으로 나타났다. 네 번째 직업은 태도에 영향을 미치는 것으로 나타났다. 다섯 번째 태도가 이용의도에 영향을 미치는 것으로 나타났고 여섯 번째는 기술숙련도가 이용의도에 영향을 미치는 것으로 나타났다. 본 연구에서는 IT 기술과 시각예술 콘텐츠가 접목된 플랫폼에 대한 변수들 간의 관계를 통해서 융복합적 연구를 시도하기 위한 연구 모형을 제시하고자 했다. 하지만 인간의 선택이라는 행위는 합리적 선택만이 아닌 각 개인의 정성적인 원인에 의해서 일어날 수 있다. 그러므로 시각예술인의 정성적인 변인이 반영된 결과가 나올 수 있도록 인터뷰와 같은 질적 연구 방법을 추가로 적용하고 혼합적 연구방법을 진행하는 것이 옳다고 보았다. 따라서 향후 연구에서는 다양한 직종과 변수들을 설정하여 시각예술 디지털플랫폼 서비스 수용의도에 영향을 미치는 요인에 관한 한층 더 심도 있고 지속적인 연구를 통해 예술복지경영의 이론적 토대들과 학문적 성과들이 만들어질 것으로 기대가 되어진다. This study aims to examine the factors influencing the intention and behavior of users on online digital platforms using the Technology Acceptance Model (TAM). A survey was conducted offline to analyze the proposed research model and hypotheses. The application of TAM to the adoption of digital platforms by visual arts professionals yielded the following findings: Firstly, technological proficiency significantly impacts both attitude and usage intention. Secondly, perceived usefulness was found to affect attitude, suggesting that recognizing the benefits of using digital platforms fosters a positive attitude towards their use. Thirdly, perceived ease of use also influences attitude. Fourthly, profession impacts attitude. Fifthly, attitude was shown to influence usage intention, and sixthly, technological proficiency impacts usage intention. This study proposes a research model intended to explore the interdisciplinary relationships among variables in platforms that integrate IT technology and visual arts content. However, human choices are not solely rational and can be driven by qualitative personal reasons. Therefore, it is appropriate to include qualitative methods like interviews in future research to reflect the subjective variables of visual artists. Future research will set diverse professions and variables to deeply and continuously investigate the factors affecting the acceptance intention of visual arts digital platform services, expecting to contribute to the theoretical foundation and academic achievements in arts welfare management.

황인천,김진,김형민,김도익,김선곤,김상수,장철,Hwang, In-Cheon,Kim, Jin,Kim, Hyeong-Min,Kim, Do-Ik,Kim, Sun-Gon,Kim, Sang-Su,Jang, Cheol 한국응용곤충학회 2009 한국응용곤충학회지 Vol.48 No.1

멀구슬나무와 고삼 식물추출물을 활용한 KNI3126의 주요 해충 6종에 대한 살충효과와 천적류에 대한 영향평가를 하였다. 벼멸구에 대한 KNI3126의 살충효과는 약제처리 후 5일째에 95% 이상이었으며, 목화진딧물은 처리 후 3일째에 95% 이상을 나타냈지만, 5일째에는 다소 살충효과가 떨어졌다. 오이총채벌레에서는 68.1%로 일반 살충제처럼 높은 살충효과를 나타내지는 않았다. 배추좀나방의 경우는 95% 이상의 높은 살충율을 나타내어 친환경자재로서 난방제 해충의 밀도 억제가 가능할 것으로 판단되었다. 점박이응애에서는 살포 1일째부터 80% 정도의 살비율을 보여 5일째에는 90% 이상의 높은 살비율을 나타냈다. 포식성 천적인 이리응애류에 대한 영향평가 결과 국제생물방제협회(IOBC)의 생존율 40%이하인 선택독성이 중간정도로 판정되었으며, 기생성 천적의 경우에는 비교적 안전한 것으로 평가되었다. 벼멸구에 대한 기피효과는 약한 것으로 판단되었지만, 점박이응애에 대해서는 높은 것으로 판명되었다. 또한, 안전성을 검토한 결과 급성경구, 급성경피, 어독성에서 저독성으로, 피부자극성과 안점막자극성시험에서는 자극이 없는 것으로 나타났다. KNI3126 which is the eco-friendly material made by plant extracts - neem and matrine - have been evaluated for efficacies against 6 main pests and toxicity on natural enemies. Insecticidal efficacies of KNI3126 against plant hopper were above 95% at 5 days after treatment (DAT), whereas pesticidal effects against the cotton aphid were above 95% at 3 DAT and slightly decreased at 5 DAT. Insecticidal efficacy against the palm thrips resulted in lower control value as 68.1% than that of chemical insecticides. KNI3126 showed more than 95% control value against diamond back moth, suggesting that it could suppress the population of pest hard to control as eco-friendly material. Mortalities against two-spotted spider mite were about 80% at 1 DAT and over 90% at 5 DAT, respectively. For evaluation of the toxicity on natural enemies, effect against predatory natural enemy was classified as moderate selective toxicity based on the criterion of International Organization of Bio-Control (IOBC), whereas against parasitic natural enemies was found to be relatively safe. Repellent effect was weak against plant hopper, but strong against two-spotted spider mite. In the toxicity test for safety, KNI3126 was classified as the lowest level at acute oral, acute dermal and fish toxicity test and did not induce the irritancy at skin irritation test and eye irritation test.

본 연구는 유기재배 배 과수원 시비에 있어서 화학 비료 대체를 위한 녹비작물 재배 이용기술 개발을 확립하고자 호밀과 헤어리베치의 파종시기에 따라 녹비 작물의 생육과 양분 공급량에 미치는 영향을 구명하기 위해서 수행되었다. 녹비직물의 파종시기는 2008년 9월 27일, 10월 15일, 11월 8일, 12월 10일로 나누어서 전남 보성의 배 과수원 독농가에 처리하였다. 관행 방임 초생 재배구는 대조구로 선정하였다. 호밀의 생육은 파종시기에 따라 별다른 차이 없이 비슷한 경향이었으나 헤어리베치는 파종 시기가 늦을수록 초장이 짧아지고 엽수와 줄기수가 감소하였고 건물중에도 그러한 비슷한 경향이 관찰되었다. 9월 하순 녹비처리는 관행 방임 초생 재배구에서 생산한 362㎏/10a의 건물 중 보다 2.6배 높았다. 파종시기별 전질소 농도는 파종 시기가 늦을수록 증가하는 경향이었으며, 전질소 환원량은 파종 시기가 빠른 9월 하순처리가 16.9㎏/10a 으로 관행대비 2.6배 높았다. 인산 환원량은 10월 중순 파종이 가장 높았으며, 칼륨 환원량은 파종 시기가 빠를수록 증가하는 경향을 나타내었다. This study was conducted to evaluate the effects of seeding time of ryegrass + hairy vetch on the nutrient contribution and growth of the crops, in order to develop utilization of cover crops as an organic nutrient source in a pear orchard. The study was conducted at a diligent farmer in Boseong in Chonnam, and the both ryegrass and hairy vetch applied on 1) 27 September, 2) 15 October, 3) 8 November, and 4) 10 December of 2008 as a cover crop treatment. Sod culture was refereed as a control. Growth of ryegrass was not affected by seeding time, but hairy vetch had fewer leaf and shoot number as seeding time advanced from September to December, and the similar trend was observed for the dry weight of the crops by seeding time. Seeding of cover crop on September was 2.6 times greater dry weight than those of the sod culture (362 ㎏/10a). Higher N concentration in cover crops occurred on early seeding time, and estimated N contribution from the cover crops was 16.9 ㎏/10a, which was 2.6 times greater than those of sod culture. P₂O? production from the cover crops was the greatest on seeding of October, and K₂O production increased at earlier seeding time.

We measured the traceability error for nine high temperature calibration service centers including type S through the round-robin test. In this test the type S thermocouple, which used as a calibration standard thermometer commonly, was accommodated as a test thermocouple. Intercomparison data of three institutions were coincident with KRISS`s data within ±0.5℃, which was the calibration uncertainty of the type S thermocouple, but the remaining six institution`s data were deviated from the assigned uncertainty level. Deviation of the intereomparison data increased gradually according to the increase of the test temperature, and the maximum difference was so large as about 2.0 ℃ at the highest test temperature, gold point. In this study found the traceability error of high temperature calibration service center for a high temperature standard was within 2.0℃.

We have investigated, by a quantitative evaluation method, the efficiency of the removal of particulate matter that was attached to clothing, by using a clothing care system. We utilized a proper, standard image-processing method as well as experimental conditions which simulated an outdoor environment in order to ensure reliability. The kinetic energy loss, which occurred during the energy transfer, which was required to detach the dust particles from clothing was also studied with visual evidence in the form of high-speed images. The development of this method for the evaluation of particle removal which is based on direct, visual measurements, instead of indirect analogous interpretations, is expected to be useful for various fields that require precise quantitative evaluation.

The occurrence of tobacco whiteflies, Bemisia tabaci, in greenhouses was monitored in Korea in 2005. Bemisia tabaci occurred in the rose, sweet pepper, tomato, and cucumber greenhouses of Chungbuk, Chungnam, Gyongnam, and Jeonnam Provinces, but not in Jeonbuk and Gyongbuk Provinces. The biotypes and genetic differentiation of the whiteflies collected in each regions were analyzed by mitochondrial 16S DNA sequences. The 16S DNA sequences of Jincheon (Chungbuk Province) samples were similar to DNA data reported from Japan and Israel which were known as the B biotype. However, the DNA sequences of the Buyeo (Chungnam), Geoje (Gyongnam) and Boseong (Jeonnam) collections, which were 100% homologous showed over 99% similarity to the DNA of Q biotype from Spain and Egyrt. Here we report the first founding of the Q biotype in Korea. It is assumed that, unlike the B biotype reported from Jincheon since 1998, the Q biotype might have been introduced recently from the certain foreign region/country to the greenhouses in those provinces. 2005년 5월 충청이남 지역의 온실에서 담배가루이의 발생 상황을 조사한 결과 충남 북, 전남 및 경남에서 착색단고추, 토마토, 오이, 장미 등의 시설 재배지에 담배가루이가 발생한 것을 확인하였으나 전북과 경북에서는 발견할 수 없었다. 각 지역별로 발생한 담배가루이의 계통(biotype)과 근연관계를 조사할 목적으로 충을 채집하여 16S DNA 염기서열 분석을 수행하였다. 그 결과 진천에서 채집한 담배가루이의 16S DNA 염기서열은 일본 및 이스라엘에서 보고된 B 계통의 DNA와 상동성이 높았고 충남 부여, 경남 거제 및 전남 보성 채집 충은 상호간에 동일한 염기서열을 보여 주었으며 스페인과 이집트의 Q계통의 DNA와 99% 이상의 높은 상동성을 보였다. 그러므로 본 논문은 담배가루이 Q 계통이 국내에 유입되었음을 알리는 최초의 보고이다. 이는 1998년부터 진천에서 발생한 담배가루이 B 계통과는 별도로 담배가루이 Q 계통이 최근에 국외의 동일한 지역내지는 국가로부터 이들 지역의 시설재배지에 유입된 것으로 추정된다.

This study was carried out for looking into the status of susceptibility of vinyl house insect pests to insecticides. The Thrips (Thrips palmi and Frankliniela occidentalis), Mites (Tetranychus urticae), Aphids (Aphis gossypii) and Whitefly (Trialeurodes vaporariorum) were captured at various areas where the host crop was being cultivated and the susceptibility level of each pest insect was investigated. The susceptibility of each pest insect varied by insect species and areas where they were caught. The tested insecticides showed good control effect to palm thrips in 2000, but in 2003 showed decrease of effect to them. Western flower thrips showed low susceptibility to neonicotinoids, imidacloprid and thiamethoxam, but high to chlorfenapyr, spinosad, emamectinbenzoate and fipronil. Antibiotic insecticides, abamectin and milbemectin, and chlorfenapyr were very effective on mite control and dicofol still had good effectiveness to it despite of long year use. No aphid species showed resistance to pyrethroid and carbamate insecticides. Relatively new insecticides such as imidacloprid, spinosad, pymetrozine were effective to whitefly, but not were organophosphates, carbamates and pyrethroids.
