Background and objective: The elderly living in homeless living facilities for a long time suffer from various mental health problems. This study aims to determine the psychological, emotional, and social effects of a horticultural therapy program composed of gardening activities, which was designed based on the semantic structures of life for the homeless elderly living in the facilities for a long time. Methods: A total of 12 subjects (6 in the control group and 6 in the experimental group) participated in the study. The horticultural therapy program consisted mainly of gardening activities, and a total of 16 sessions were conducted once a week for 16 weeks, 60-90 minutes per session. The subjects were tested to evaluate their self-esteem, depression, and horticultural activities. The data were analyzed using the Mann-Whitney U test, Wilcoxon rank test, and Friedman test, which were nonparametric tests, conducted at a 95% significance level. Results: First, in the case of self-esteem, a significant difference was found between the groups, 20.00 points (SD = 5.69) in the control group, and 25.50 points (SD = 3.73) in the experimental group (p = .034). Second, in the case of depression, no statistically significant difference was found in the posttest. Finally, in the case of the horticultural activity evaluation, the scores of most variables gradually and significantly increased during the program [Verbal interaction during activity (p = .006), Self-concept and identity (p = .006), Need-drive adaptation (p < .001), Interpersonal and social relations (p < .001)]. Conclusion: These results support that the horticultural therapy program could help the elderly improve psychological relaxation, emotional stability, and social relationships. In order to generalize the results, it is suggested to increase the number of subjects or conduct additional repetitive experiments in further research.

It is necessary to evaluate the location suitability for protected horticulture to plan new protected horticultural facilities in rural areas. For objective and systematic evaluation of location suitability for protected horticulture, three different evaluation models were constructed based on grading, proportion, and analytic hierarchy process(AHP). The three methods were tested to evaluate the location suitability for protected horticulture in three selected regions; suburban, plain, mountainous. The results indicated that the grading method underestimated the difference of importance among grouping categories, compared to the proportion and AHP methods. Based on the results, the AHP method was founded to be better than the other two methods in terms of evaluation process, reproductivity and reliability of the results.

Geothermal heat pump systems use the earth as a heat source in heating mode and a heat sink in cooling mode. These systems can be used for heating or cooling systems in farm facilities such as greenhouses for protected horticulture, cattle sheds, mushroom house and etc. A horizontal type means that a geothermal heat exchanger is laid in the trench buried in 1.2 to 1.8 m depth. Because a horizontal type has advantages of low installation, operation and maintenance costs compared to a vertical type, it is easy to be adopted to agriculture. In this study, to heat and cool farm facilities and obtain basic data for practical application of horizontal geothermal heat pump system in agriculture, a horizontal geothermal heat pump system of 10 RT was installed in greenhouse. Heating and cooling performance of this system was estimated. The horizontal geothermal heat pump used in this study had heating COP of 4.57 at soil temperature of $14^{\circ}C$ with depth of 1.75m and heating COP of 3.75 at soil temperature of $7^{\circ}C$ with the same depth. The cooling COP was 2.7 at ground temperature at 1.75m depth of $25.5^{\circ}C$ and 2.0 at the temperature of $33.5^{\circ}C$.

본 연구에서는 시설감귤농가와 시설포도 농가들을 대상으로 농업 에너지 절감시설과 신재생에너지원의 이용행태를 조사 분석하였다. 농가들의 에너지 이용행태를 조사한 결과, 농업 에너지 절감 시설과 신재생에너지의 이용 및 운영 관리 시스템은 여전히 미흡한 수준으로 나타났다. 시설감귤 농가와 시설포도 농가를 대상으로 실시한 IPA분석 결과에 따르면, 에너지 절감시설과 관련된 항목들에 대하여 전반적으로 중요도는 높았으나 수행도(만족도)는 크게 낮은 것으로 나타났다. 유류비 부담 등으로 인해 재배면적이 감소추세에 있는 시설감귤 농가의 경우 '관련 보조시설 확충 지원'이나 '기술개발', '저비용 대체에너지 보급문제'에 대해서는 중요하다고 판단되지만 실제 수행도는 매우 낮게 나타났다. 반면 재배면적이 증가하고 있는 시설포도농가의 경우 '에너지 절감시설에 대한 AS 용이성', '지역별 여건을 고려한 지원정책', '절감시설에 대한 기술개발'에 대해서 모두 우위를 나타냈다. 영농 광열비의 증가는 결국 농가경영에 부담을 증가시키고 대외 경쟁력을 떨어뜨리는 위험성을 갖고 있다. 현재 농가들이 사용하고 있는 등유는 열효율적인 면에서 손실이 많기 때문에 경유, 증유 등을 지속적으로 사용 할 수 있도록 기존 노후화 시설에 대한 개보수 지원과 함께 대체에너지의 보급 확대를 위한 방안이 마련되어야 한다.

In this study, RPS system, one of the renewable energy support systems, is utilized for economic analysis of solar generation equipment and the fuel cost savings plan for controlled horticulture farms with high fuel-cost dependency and facility applicability were evaluated. On the exterior of the upper layer of glass greenhouse (9917$m^2$) of controlled horticulture farms using bunker C oil, half of the area (4958$m^2$) was utilized for theoretical installation and operation of 450kW-level solar power generator, and as the result, first, the effect of investment cost only of solar generation system was found to be quite excellent, but it was analyzed that there were limits to saving the fuel costs of the controlled horticulture farms. Second, when geothermal system was first introduced in the farm and solar system was additionally introduced, it was analyzed that the effect of introducing solar system was excellent. In order to apply such effects to the sites of farming, partial supplementation of RPS system which is being uniformly applied regardless of the purpose of renewable energy is necessary. When the subject of use directly install facilities where it is directly connected to national added-value such as food security created by the farming industry, it is necessary to introduce appropriate system that corresponds to such. Moreover, it was studied that the quick development of demonstrative complex that can practically evaluate the applicability of renewable energy in farming industry and interest and preparation of related institutions in financial support structure for its site application would lead to success.
