파프리카 생산성은 동일한 품질 온실, 지역 간에 차이를 나타내고 있다. 이러한 차이는 다양한 환경요인의 차 이에서 오는 것으로 알려져 있다. 본 연구는 동일 지역에서 동일 품질 온실 중에서 생산성이 높거나(HPF) 낮은 (LPF) 온실 간 내부 환경요인의 수준 차이를 알아보고자 수행되었다. 주요 환경요인들의 일 또는 주의 평균값에서 두 온실 간에 가장 큰 차이를 보인 것은 CO2 농도였지만, LPF에서 HPF보다 매우 높아 생산성 차이 요인으로 판정 하기 않았다. 14개 환경 요인들 간 상관분석에서 광량과 수분 관련 요인들 간에 상관성을 나타내었다. 증산량에 관련 된 수증기압포차와 상대습도 간 선형회귀모형의 회귀계수는 HPF에서 -0.0202kpa, LPF에서는 -0.0262kpa로 나타났 다. 특히 2월과 3월에는 LPF에서 VPD가 1.5kpa 이상이었고, 재배 초기에 누적 광량 대비 누적 수증기압포차의 급격 한 증가가 나타났다. 따라서 LPF에서 생산성이 낮은 원인은 재배 초기와 겨울철에 적은 광량 조건에서 높은 VPD에 의한 높은 증산량이 식물체에게 수분 스트레스를 주었기 때문으로 판단된다. Paprika productivity is different even in the same quality greenhouse and in the same region. These differences are known to due to differences in various environmental factors. This study was conducted to investigate the difference in the level of various environmental factors between high-productivity (HPF) and low-productivity (LPF) greenhouses. The largest difference between the two greenhouses in the daily or weekly average values o f major environmental factors was the CO2 concentration, but the LPF was higher than the HPF, so it was not determined as a factor for the difference in productivity. Correlation analysis among 14 environmental factors showed a high correlation among irradiation or related factors in moisture. The regression coefficients of the linear regression model between vapor pressure deficit and relative humidity were -0.0202kpa in HPF and -0.0262kpa in LPF. In particular, in February and March, the vapor pressure deficit in LPF was 1.5kpa or more, and the cumulative vapor pressure deficit compared to the cumulative irradiation at the early period of cultivation increased rapidly. The reason for the low productivity in LPF is thought to be that the plant was affected by moisture stress due to high vapor pressure deficit and transpiration under low irradiation conditions in the early period of cultivation and in winter.

[북한의 미술과 미술사 (上)] 주체미술의 형성과 전개

김가영 북한연구소 2019 北韓 Vol.- No.568

전체주의 체제에서 미술은 인민을 동원하고 선동하는 프로파간다 수단 중 하나다. 북한에서도 미술은 내부 결속과 수령 우상화, 체제 선전, 외화벌이를 위해 대내외로 활용돼 왔다. 그랬던 북한 미술이 최근 남북 해빙무드에 맞춰 국내 전시장 곳곳에 걸리고 있다. 과연 북한 미술을 예술 그 자체로 바라볼 수 있을까? 그 답을 찾기 위해 해방 이후부터 오늘날까지의 북한 미술사를 세 번에 걸쳐 되짚어보려 한다. 첫 주제는 북한 미술사의 근간인 ‘주체미술’과 ‘조선화(朝鮮畵)’의 형성 과정이다.

다중 지역기후모델을 이용한 동아시아 상세 기후변화 전망

In this study, global climate change scenario by HadGEM2-AO is dynamically downscaledusing 5 Regional Climate Models (RCMs) for the Coordinated Regional Downscaling Experiment(CORDEX) - East Asia. All RCMs with 50-km horizontal resolution are integrated for continuous 71years (1979-2049). In the evaluation of historical runs, all models tend to overestimate precipitation overthe subtropical western North Pacific. For the surface air temperature, all models have cold biases overthe East Asian continent compared to the observation. In the future projections, all models show similarchanges in precipitation such as increasing precipitation over the tropical oceans and slightly decreasingprecipitation over the East China Sea. In the mid-latitudes, convective precipitation tends to increase dueto the enhanced convective instability, while non-convective precipitation tends to decrease slightly dueto the changes in subtropical high and monsoon circulation. For surface air temperature, the warmingtendency over the entire domain is captured by all models and it is larger in high latitude regions. Thewarming temperature is related to the increase in longwave radiation, which leads to prominent increase inminimum surface air temperature.

Cognitive Stimulation as a Therapeutic Modality for Dementia: A Meta-Analysis

김가영,한지원,소윤섭,서지영,김유정,박준혁,이석범,이정재,정현강,김태희,김기웅 대한신경정신의학회 2017 PSYCHIATRY INVESTIGATION Vol.14 No.5

Objective: Although cognitive stimulation (CS) is one of the most popular non-pharmacological interventions for people with dementia, its efficacy is still debatable. We performed a meta-analysis of randomized controlled trials (RCTs) on the efficacy of CS in people with dementia. Methods: Data sources were identified by searching PubMed, MEDLINE, Embase, psychINFO, and Cochrane Reviews Library. A total of 7,354 articles were identified, and of these, 30 RCTs were selected based on the selection criteria. Of these 30 RCTs, 14 were finally included in our meta-analysis [731 participants with dementia; 412 received CS (CS group) and 319 received usual care (control group)]. Results: We found that the people with dementia had a moderate benefit from CS. The mean difference between the CS and control groups was 2.21 [95% CI (0.93, 3.49), Z=3.38, p=0.00007] in the Alzheimer’s Disease Assessment Scale-Cognition and 1.41 [95% CI (0.98, 1.84), Z=6.39, p<0.00001] in the Mini-Mental State Examination. CS also improved quality of life in people with dementia [95% CI (0.72, 3.38), Z=3.02, p=0.003]. Conclusion: CS is effective for improving cognition and quality of life in people with dementia; however, its effects were small to moderate.

Sulfonated Poly(ether ether ketone) 및 Poly(vinyl amine)/poly(vinyl alcohol) 혼합막이장착된 막결합형 축전식 탈염공정의 성능 연구

김가영,임지원 한국막학회 2016 멤브레인 Vol.26 No.1

In this study, sulfonated poly(ether ether ketone) (SPEEK) as cation exchange membrane and blended and crosslinked poly(vinyl amine) (PVAm) with poly(vinyl alcohol) (PVA) membrane as anion exchange membrane were used and then the performance experiments of the membrane capacitive deionization (MCDI) installed with both membranes were carried out. The newly prepared anion exchange membrane were characterized through water content, ion exchange capacity and FT-IR. The crosslinking time of 3 h to 5 h indicated that the salt removal was reduced from 81.3, 65.7% to 53.8%. The effect of PVAm contents from 40, 60, to 80% on the salt removal was shown 81.3, 75.2 and 37.7%, respectively. As a result, it was concluded that the crosslinking time and the content of PVAm had an influence on the salt removal efficiency. 본 연구에서는 양이온 교환막으로 Sulfonated poly(ether ether ketone) (SPEEK)를 사용하였고, 음이온 교환막은poly(vinyl alcohol) (PVA)과 poly(vinyl amine) (PVAm)을 혼합하여 가교시킨 막을 이용하였으며, 이에 대한 막결합형 축전식탈염 공정(Membrane capacitive deionization, MCDI)의 성능실험을 진행하였다. 음이온 교환막의 함수율, 이온교환용량, FT-IR 측정을 통하여 막의 특성을 알아보았다. 음이온 교환막의 가교 시간이 3 h에서 5 h으로 증가할수록 염 제거 효율은81.3%에서 65.7, 53.8%로 감소하였다. PVAm의 농도를 40, 60, 80%로 달리하여 실험한 결과 염 제거 효율은 81.3, 75.2, 37.7%로 PVAm이 80% 함량일 때 가장 효율이 떨어졌다. 이는 음이온 교환막의 가교 시간과 PVAm의 농도가 염제거 성능에영향을 미치는 것으로 사료된다.

김가영,이선재 한국의류학회 1995 한국의류학회지 Vol.19 No.2

This study intended to provide valuable basic data for an efficient using newspaper advertising to manufactures by investising and analyzing the character of newspaper as fashion advertising and media environment, consumer's attitude of advertising subscription, a degree of recognition and concern on a newspaper advertising and a degree of like on expressive form of a newspaper advertising. A question that is drawn up by researcher base on existing records and preceding study was used as major method for understanding consumer's consciousness. The sample group is composed of female students, working women, housewives who lives in Seoul. The results of this study were as follows. 1. Manufactures should be developing Headline in subject matter to get out of plain sale advertising and event advertising. 2. Manufactures should difference to understanding Illustration that consumer prefer. Also using of photography is efficient and it is importent to use of color advertising that appeal to consumer. 3. The informative advertising is a high degree of efficiency by reason that the newspaper offers great news source and information.
