Background and objective: Agro-healing is crucial with urban farming in the domestic. It is beyond the conventional agriculture. This study was carried out to assess the 2010s researches on domestic agro-healing and predict the future direction of agro-healing development. Methods: Among the articles published from 2010 to 2018, we collected some articles by searching keywords including agro-healing, garden activity, gardening, horticultural activity, horticultural program, horticultural therapy, plant effect, plant environment, plant growing program, plant impact, social gardening, urban agriculture and vegetable garden activity, selected 83 articles that were evaluated in advance, and analyzed by frequency analysis, t-test, and one-way ANOVA with SPSS 20.0. Results: Agro-healing journal articles were published the most in 2010, and have declined since then. In the classification according to the academic society, most of the journal articles were published by the Society for People, Plants, and Environment. The main targets of domestic agro-healing related to activities and programs were preschoolers, children and adolescents, accounting for 52.4% of the total. By the characteristics of the subjects, agro-healing programs and studies were conducted with special participants who needed special care compared to the general participants. The dependent variables were classified into six areas according to their attributes and the share of psychological and emotional areas was highest (42.6%) among them. In terms of the composition of the program, the share of those with 9-12 sessions was highest (36.7%) and the share of those with more than 20 participants was also highest (39.8%). Conclusion: It is recommended to operate agro-healing programs or industries focusing on the socially disadvantaged including those who have special needs or the underprivileged, but in order to create income for farms and expand the demand for agro-healing, it will be necessary to spread the perception that anyone without any physical or emotional issue can be the targets of and experience agro-healing. To meet the different needs of targets of agro-healing, it will be necessary to conduct objective and practical studies on broader areas and in the process the healing functions of agriculture and the strength of agro-healing needs to be further highlighted.
주말농장 참여 노인의 식물재배 활동수준이 주관적 건강, 우울, 인간관계에 미치는 영향

Korean agriculture experienced rapid changes in its production structure to respond fluctuations on external conditions, and these changes have increased the dependence between agricultural resources and negative environmental externalities from agricultural production. As a tool for managing agricultural resources and reducing negative environmental effects from agricultural production, this study employs water-energy-food nexus for integrated resource management. To show the necessity of an integrated approach, this study evaluated three policy scenarios including changes in capital interest, water capacity, and energy cost. The results show that three scenarios have unintended consequences for farmers’ incomes and their use of resources. Also the unintended consequences of government policies also affected farms’ vulnerability to environmental changes. In particular, the expansion of financing for the establishment of non-circulating water curtain facilities did not have a significant effect on the crop switching of farms. In addition, increasing the amount of available water through the aquifer recharge project leads to the installation of non-circulating water curtain facilities in zucchini farm. It raises dependence on groundwater in agricultural production, thereby increasing farmers’ vulnerability to groundwater shortages. These results imply that the agricultural sector needs to consider the interrelationship between agricultural resources when designing or evaluating policies.

N/A Background: The demand for refinement in noninvasive and quantitative assessment of left ventricular (LU) function is increasing. Purpose : To assess normal values of left ventricular functional parameters during both systole and diastole hy scintigraphic method using computerized triple-head gamma camera and to evaluate correlations between these parameters. Methods .' ECG gated blood pool scan with Tc#-Hurnan serum albumin was performed in 94 normal Korean;ubjects. Ejection fraction (EF), systolic parameters [peak emptying rate (PER), average emptying rate (AER), tirne to peak emptying rate (TPER)], and diastolic parameters [peak filling rate (PFR), average filling rate (AFR), time to peak filling rate (TPFR)] were obtained by analysis of LV time-activity curve, the correlation of these parameters to the age and sex, and the correlation between these parameters were evaluated. Results : 1) Mean value of ejection fraction in study subjects was 59.6 +- 5.25% and showed no significant correlation to age (r=0.08) and sex but showed most pronounced correlation to PFR (r=0.46, p<0.001), PER (r=0.41, p<0.001), AFR (r=0.34, p<0.001) and AER (r=0.28, p<0.01). 2) Mean values of systolic parameters were as follows: PER=3.22+ 0.50 end-cliastolic volume/sec, AER =2.22+0.45 end-diastolic volume/sec, TPER=103.5+29.30 msec. They showed no significant correlation to age and sex. 3) Mean values of diastolic parameters were as follows: PFR=2.71+0.51 end-diastolic volume/sec, AFR=1.830.44 end-diastolic volume/sec, TPFR=132.1+33.45 msec. They showed strong correlation to age <r=- 0.70, 0.64, 0.37, p<0.001). Conelwions . Left ventricular functional parameters in normal Korean subjects were obtained reliably by computerized scintigraphic method and may be applied to the evaluation of cardiac function in diseased patients.

The purpose of this study was to investigate the preference of plant environmental images for flower plant consumption. This study came up with a total of four treatments including one image without plants and three images with flower plants (three roses, rose gift, rose garden). We conducted a survey on 104 men and women through the Google (online) survey and analyzed the data. The preference was higher with statistical significance for environmental images with plants than the image without plants. The preference for environmental images of roses was highest in the order of rose gift > rose garden > three roses. As a result of the cross-tabulation analysis, it was found that there was a significant difference in the preference for environmental images of roses according to general characteristics such as educational background and residence type. In terms of educational background, 2-year college graduates showed higher preference for the three environmental images of roses with statistical significance compared to high school graduates, university graduates and masters or higher. As a result of determining the difference in preference according to residential types, residents of multiplex houses showed higher preference for the “rose garden” environment image than residents of detached houses (p < .05). As a result of examining stress and depression in everyday life, 48.1% (the highest) of the respondents answered that they were “under daily stress” and 48.1% (the highest) of the respondents claimed not to be “under much depression”. This study investigated the difference in preference according to demographic characteristics and existence of plants, preference in environmental images using roses, correlation with daily stress and depression, and utility of publicity using photographic images of plants.

본 논문에서는 ANSYS 소프트웨어를 사용하여 회전시료조사대의 진동특성을 공기중 및 수중에서 평가하였다. 수중에서 진동해석에서 사용된 추가질량은 Blevins가 제시한 수식을 이용하여 계산하였다. 본 논문에서 제시한 결과의 타당성을 확인하기 위하여 구해진 결과는 이론적인 식을 사용해 구한 결과와 비교하였다. 유체의 추가질량 효과 때문에 회전시료조사대의 고유진동수는 공기 중에서 보다 수중에서 낮아짐을 확인할 수 있었다. 그리고 회전시료조사대의 고정에 필요한 클램프를 설계하기 위하여 클램프의 압력에 대한 회전시료조사대의 등가응력 및 변위를 계산하였다. In this paper, in-air and in-water vibration characteristics of Rotary Specimen Rack (RSR) are estimated through 3D finite element modeling by using ANSYS software. Added mass is calculated by using Blevins' equation. To confirm the reasonability of the results presented in this study, obtained results are compared to those of using a theoretical equation. It is confirmed that in-water natural frequencies of the RSR are lower than in-air ones due to the added mass effect of the fluid. Also, to design clamp which needs to fix RSR, Von-Mises stress and displacement of RSR to clamp pressure are calculated.
