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.

To protect and manage the Korean space assets including satellites, it is important to have precise positions and orbit information of each space objects. While Korea currently lacks optical observatories dedicated to satellite tracking, the Korea Astronomy and Space Science Institute (KASI) is planning to establish an optical observatory for the active generation of space information. However, due to geopolitical reasons, it is difficult to acquire an adequately sufficient number of optical satellite observatories in Korea. Against this backdrop, this study examined the possible locations for such observatories, and performed simulations to determine the differences in precision of optical orbit estimation results in relation to the relative baseline distance between observatories. To simulate more realistic conditions of optical observation, white noise was introduced to generate observation data, which was then used to investigate the effects of baseline distance between optical observatories and the simulated white noise. We generated the optical observations with white noise to simulate the actual observation, estimated the orbits with several combinations of observation data from the observatories of various baseline differences, and compared the estimated orbits to check the improvement of precision. As a result, the effect of the baseline distance in combined optical GEO satellite observation is obvious but small compared to the observation resolution limit of optical GEO observation.

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.

Golden hamsters are seasonal breeders whose reproductive activities are active during summer. Their sexual function is completely suppressed in winter. In oriental society, traditional medicines have been utilized in treating various complaints. One of them is Cynomorium songaricum (CS) whose extract has been used in treating male impotence and sexual dysfunction. We investigated the effects of aqueous CS extract on the process of spermatogenesis in golden hamsters. The animals were divided into 4 groups: long photoperiod (LP) control, short photoperiod (SP) control, and SP animals treated with low or high concentrations of CS. The animals were daily intubated with low (1.25 g/kg) or high (2.50 g/kg) concentrations of the CS aqueous extracts for 8 weeks. The control animals received the vehicle. The volume of testis was measured consecutively from the same animal at 4 week intervals. As results, the LP control animals showed large testes that indicate reproductively active function, but SP control animals displayed remarkably reduced testes that reflect inactive function. The outcomes of the reproductive activity from low concentrations of CS were not conspicuous. And the integral consequences of the reproductive activity from high concentrations of CS treatments were not significant either. But in tracing the individual animals treated with high CS extract, the effects were evidently splitted into dichotomy. In one subgroup small testes were displayed as in SP control animals, but in the other subgroup large testes were demonstrated as in LP control animals, which implies the absolute prevention of regressing activity by SP. These results suggest that the CS extract has a potency to prevent the regressing effects of SP and promotes the male fertility by strengthening the spermatogenesis in the golden hamsters.

Agriculture plays a vital role in the sustenance of human society and is the fundamental of developing economies. Nitrogen is one of the most critical inputs that define crop productivity. To ensure better value for investment as well as to minimize the adverse impacts of the accumulative nitrogen species in environment, improving nitrogen use efficiency of crop plants is of key importance. Efforts have been made to study the genetic and molecular biological basis as well as the biochemical mechanisms involved in nitrogen uptake, assimilation, translocation and remobilization in crops and model plants. This review gives an overview of metabolic, enzymatic, genetic and biotechnological aspects of nitrogen uptake, assimilation, remobilization and regulation. This review presents the complexity of nitrogen use efficiency and the need for an integrated approach combining physiology, quantitative trait genetics, system biology, soil science, ecophysiology and biotechnological interventions to improve nitrogen use efficiency.

"Sunny Gold", an Asiatic lily variety was released by the National Horticultural Research Institute (NHRI), in 2006. A cross was made between a yellow colored Asiatic lily variety "Mona" and a light yellow colored Asiatic lily variety "A93-15(Sunray x Foxtrot)" in 1996. Selection was made in the natural cultivation condition from the progenies derived from the cross between "Mona" and "A93-15" in 1998. The flower characteristics and performance of "Sunny Gold (line name was Wonkyo C1-88)" were investigated from 2000 to 2005. Although its flowering time is middle of the June, year-round cut flower production was possible by storing the bulbs at -1 or -2℃. It has unspotted, upward facing, and yellow petals with no fragrance. The plant height is 87.3 cm. The width of flower is 14.2 cm. The weight and circumstance of bulb are 15.2 g and 10.9 cm, respectively. For forcing culture, it is necessary to add calcium to the fertilizer or remove side scales to prevent leaf scorch. Botrytis disease should be properly controlled especially in wet season.

"Pinky Smile", an Asiatic lily variety was released by the National Horticultural Research Institute (NHRI), in 2006. A cross was made between a light pink colored Asiatic lily variety "Marlene" and a white colored Asiatic lily variety "Pinguin" in 1998. Selection was made in the natural cultivation condition from the progenies derived from the cross between "Marlene" and "Pinguin" in 2000. The flower characteristics and performance of "Pinky Smile (line name was Wongyo C1-82)" were investigated from 2001 to 2005. Although its flowering time is early June, year-round cut flower production was possible by storing the bulbs at -1 or -2℃. It has unspotted, upward facing, and ivory-pink (RP62A+W155B) petals with no fragrance. The plant height is 107 cm. The width of flower is 13.9 cm. The weight and circumstance of bulb are 39.3 g and 15.4 cm, respectively. For forcing culture, it is necessary to add calcium to the fertilizer or remove side scales to prevent leaf scorch. Botrytis disease should be properly controlled especially in wet season.

A new gerbera variety 'Claret' was released by the National Horticultural Research Institute (NHRI) in 2006. A cross was made between 'Rako' with pink and semi-double and 'Sessile' with orange and single in 2000. After investigation of the characteristics for 6 years (from 2000 to 2006), it was selected specially for the use of cut-flower. 'Claret' is vigorous cultivar with purple and semi-double. It produces a large yield with continuous supply of flowers and has adequate peduncle height and brilliant color. We believe that 'Claret' has a great potential for expanding cultivated area of domestic mini-gerbera cultivar and increasing farmers-income.

A new gerbera variety 'Peach Honey' was released by the National Horticultural Research Institute (NHRI) in 2006. A cross was made between 'Ansofie' with white and semi-double and 'Lilabella' with pink and semi-double in 2000. After investigation of the characteristics for 6 years (from 2000 to 2006), it was selected specially for the use of cut-flower. 'Peach Honey' is vigorous cultivar with salmon and semi-double. It produces a large yield with continuous supply of flowers and has adequate peduncle height and brilliant color. We believe that 'Peach Honey' has a great potential for expanding cultivated area of domestic gerbera cultivar and increasing farmers-income.

‘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.

Hopyeongbyeo is an anther culture derived Japonica rice (Oriza sativa L.) cultivar from the cross between Hitomebore and Hwajinbyeo by the rice breeding team of Honam Agricultural Research Institute (HARI), NICS, RDA, in 2003. This cultivar has a about 126 days growth duration from transplanting to harvesting. The short and round grain shape of Hopyeongbyeo is translucent with non-glutinous endosperm. Amylose content of rice grain is about 17.8% and high palatability of cooked rice compared with Nampyeongbyeo. This cultivar shows resistant to bacterial blight pathogenes of K1. The milled rice yield of Hopyeongbyeo is about 5.13MT/ha at ordinary transplanting culture in the local adaptability test. Hopyeongbyeo would be adaptable for the southern plain area of Korea.
