The purpose of this study was to analyze the relation of internal factors and to build a foundation for SWOT Matrix strategy of horticulture therapy in the domestic. 438 master’s and doctorate degree dissertations on horticultural therapy from 1998 to 2015 were analyzed with years, school groups, degree classifications and regional groups. Master’s and doctorate degree dissertations published 438 studies in 1998 (1), 2002 (13), 2007 (32), and 2012 (44) have increased continuously. Among all the 211 Korean schools, 82 published dissertations related to horticultural therapy. The schools that have published more than 10 theses are as follows. Konkuk university has published the most 67 theses. The dissertations were followed by Korea univ. (50), Dankook univ. (44), Catholic univ. of Daegu (40), Seoul national univ of education (21), univ. of seoul (15), Mokpo national univ. (12), Jeju national univ. (11), Chungnam univ. (11), Daegu univ. (10), Chosun univ. (10). In the frequency analysis of academic degree types related to 438 theses, agricultural science (39.3%) accounted for the largest percentage. The next was followed by natural science (17.6%), education (16%), social welfare (8.4%), health science (5.7%), art plastic (2.3%), literature (2.1%), special education (2.1%), engineering (1.8%), science of nursing (1.1%), design (1.7%), theology (0.7%), psychology (0.7%), natural therapy (0.7%), etc (0.9%). According to the frequency analysis of regions where 438 dissertations were published in 15 cities/provinces in South Korea except Ulsan city. The results of this study confirmed that horticultural therapy satisfied the internal environment to become a field of complementary and alternative medicine.

With the object of examining the effects of horticultural therapy based on structural recall by developmental stage on cognitive, emotional, and hand functions of institutionalized elderly, this study executed a horticultural therapy program once a week and through a total of 14 sessions during the period from May 2 to December 5, 2013. The subjects of this study were 34 elders admitted to S Geriatric hospital for geriatric diseases, and they were divided into a control group and an experimental group. Because the program was designed for institutionalized elders who were able to do only indoor activities, it provided various seasonal horticultural activities that could be done even in a limited space by giving materials and subjects that could be recalled by developmental stage. The results of this study are as follows. As to changes in cognitive functions (MSQ) after the horticultural therapy program, the control group showed a decrease as having more negative ranks, and the experimental group showed an increase as having more positive ranks, but such changes in the control and experimental groups were not significant. As to changes in emotional functions after the horticultural therapy program, the control group showed a decrease but without significance in ego integrity as having more negative ranks, and the experimental group showed an increase with significance as having more positive ranks (P=0.020). As to the experimental group’s changes in the sub factors of ego integrity, positive ranks increased in all the sub-factors and the increase was particularly significant in satisfaction with present life (P=0.038). As to changes in life satisfaction, the control group showed increased positive ranks but without significance, and the experimental group showed significantly increased positive ranks (P=0.022). As to the experimental group’s changes in the sub-factors of life satisfaction, changes in denial of the past (P=0.029) and denial of the future (P=0.016) were particularly significant. As to changes in hand functions, both the control and experimental groups showed some improvement in pinch after the horticultural therapy program but the changes were not significant. Grip strength did not change in the control group, and in the experimental group right-hand grip strength was improved slightly more than left-hand one, the difference was not significant. The results of this study suggest that horticultural therapy based on structural recall by developmental stage is effective in improving institutionalized elders’ emotional functions and, consequently, can contribute to higher quality of life, which is the ultimate goal of elders.

We investigated the effect of light spectra on circadian rhythm by exogenous prolactin (PRL) by using light emitting diodes (LEDs): red, green, and purple. We injected PRL into live fish or treated cultured brain cells with PRL. We measured changes in the expressions of period 2 (Per2), cryptochrome 1 (Cry1), melatonin receptor 1 (MT1) mRNAs, and MT1 proteins, and in the plasma PRL, serotonin, and melatonin levels. After PRL injection and exposure to green LED light, MT1 expression and plasma melatonin levels were significantly lower, but the expressions of Per2 and Cry1 were significantly higher than others. Plasma serotonin after PRL injection and exposure to red LED light was significantly lower than others. These results indicate that injection of high concentration PRL inhibits melatonin, and inhibited melatonin regulates circadian rhythm via clock genes and serotonin. Thus, exogenous PRL regulates the circadian rhythm and light spectra influence the effect of PRL in goldfish.

‘Seohong’ was bred within the potato breeding program of National Institute of Highland Agriculture (NIHA). It was originated from a cross made in 1997 between ‘Jashim’ as a female and 93K65-1 as a male parent. Seohong was evaluated as a seedling number 97S05-1 for tuber characteristics, growth and yielding ability from 2001 to 2002, and than this clone was renamed as Daegwan 1-82. This clone was evaluated in the regional yield trial and the disease resistance in the five locations for three years. Finally, this clone was named as ‘Seohong’ and registered a new recommended potato cultivar in 2006. This cultivar has a round, shallow eye depth, light red-skinned tuber characteristics and low to medium dry matter content. It showed high resistance to common scab (Streptomyces scabies) and potato leaf roll virus (PLRV), however it was susceptible to potato virus Y (PVY) and late blight (Phytophthora infestans). Its mean tuber yields from the regional yield trial and winter cropping trial were 12 and 49 percent higher than that of ‘Superior’, respectively.
