A noble method was developed for determining indoor greenery ratio through a digital camera and image analysis. Photographs with 10 different exposure compensations level were taken at indoor room using the function of “Partial color (green)” in a digital camera under varied indoor light conditions. RGB photographs were converted into Lab mode using [Image/Mode] function of Photoshop software program. The number of green pixels were calculated within 1 to 127 level (equivalent to -127 to -1 of Hunter a* value) through “Channel a” in [Histogram] function of the software. Greenery ratio was calculated by maximum green pixel number of an exposure compensation in relation to total pixel number, as maximum green pixels number would be obtained under a certain exposure compensation level when it minimizes achromatic color by partially excessive lower or higher light condition within certain area of photograph. When greenery ratio obtained from this method was compared with general greenery calculation of green area through manual selection, coefficient of determination was 0.9852, indicating appropriate greenery ratio estimating method. When applied to vertical planter of veranda and office, greenery ratio varied at 0.53～14.96%. In our experimental condition, error of the function, “Partial color” by the digital camera was within 0.013, while the error of the function, “Channel a” by the software was within 0.005.

This study was taken place to find out the psychological change with comparing before and after the experience of installation of indoor garden with 55 of subjects out of 62 subjects. More than 50% of subject answered that the garden management would be difficult before they experience the installation but the pressure was decreased while the interest of plants and landscape increased, however, the burden of management decreased and the interest in the kinds of plants and landscape design tended to increase after the experience of the installation. The psychological effect of indoor garden of workers was significantly increased with the question of “Indoor garden improves effect of air cleaning.” after the experience of installation and the loyalty was statistically increased with the question of “Intend to invest more fund to purchase indoor plant” (p <.05). As a result of the comparison of two psychological indicators, the recovery index of the state according to experience of indoor gardening was significantly higher after experiencing the indoor garden than before the indoor gardening experience. As the result of sensibility evaluation of pleasant, natural and calm with semantic differential method, workers feel more of them with the indoor garden. In addition, the loyalty was statistically significantly higher in the question “I would be willing to invest more in plant purchase” after experiencing the composition indoor garden (p <.05). This result is similar to the result that the resident’s recovery index, pleasantness, calm feeling, and emotional index are higher the indoor garden in public resting area with indoor garden than without indoor garden. With this study, the perception of indoor garden changed as a result of the worker’s experience of indoor gardening in the workplace and the view of the indoor garden created by the workers. As the psychological healing effect of indoor garden increased, increase in the cost investment for the emotional health promotion of the workers is expected to have a positive effect on the increase of the indoor garden.

Backgoound : This study was conducted to serve as a basis for the selection of superior lines by analyzing the content of antioxidant component and antioxidant activity in Schisandra chinensis Collections Methods and Results : In order to examine antioxidant component and antioxidant activity, 154 species of Schisandra chinensis from whole country were used.

As a result, the total amounts of flavonoids was highest in SC-20 with 5.03 ㎎/g. However the content of polyphenols showed highest in SC-22 with 2.76 ㎎/g. In addition antioxidant activity results were also relatively high in SC-22. The IC50 value was 548 ㎍/㎖ in DPPH radical scavenging and 640 ㎍/㎖. in ABTS+ radical scavenging. Conclusion : As demand for high income crop has increased, new cultivar breeding is required to produce high quality Schisandra chinensis From this study, analyses of antioxidant component and antioxidant activity in collection can be used for new Schisandra chinensis breeding. Especially SC-22 can be superior lines with high antioxidant component and antioxidant activity.

Background : Ginseng (Panax ginseng C. A. Meyer) is a perennial crop grown for more than 4 years in the same place. Therefore, it is highly affected by soil environment, especially nutrients on soil. This study was carried out to investigate the effects of application levels of nitrogen, phosphate, potassium on growth and soil chemical properties of ginseng. Methods and Results : 0, 1, 4, 8, 16, 32 ㎏/10 a of Urea, fused superphosphate, potassium chloride were each treated at 3.3 ㎡ of the field and ginseng cultivar 'Geumpoong' was transplanted. Growth characteristics were investigated by growth period and soil chemical properties were investigated every 3 months. As the levels of treated nitrogen increased, root weight increased from 0 ㎏/10 a to 4 ㎏/10 a and then decreased. Electrical conductivity (EC) and the NO3 content tended to increase as time goes by. As the levels of treated phosphate increased, the SPAD content increased. Soil analysis of October showed that the NO3 content of phosphate 32 ㎏/10 a treatment increased to 80.25 ㎎/㎏. In the case of potassium 32 ㎏/10 a treatment, the emergence rate was 74% and root weight was 2.06 g, which were the worst in all treatments. When the levels of treated potassium increased, the EC tended to increase gradually and the pH was decreased. Conclusion : These results indicate that the application levels of Nitrogen, phosphate, potassium influence growth of ginseng and soil chemical properties. Further research will be needed to establish appropriate standards of soil chemical properties for ginseng cultivation.

Background : Undulatum Rhubarb, commonly produced in domestic, is rhizome of Rheum undulatum L. that belongs to the family Polygonaceae. It also can be used as a substitute of R. palmatum L., R. tanguticum Maximowicz ex Balf., and R. officinale Baillon which completely depend on import system. However, there should be clear clarification among Undulatum Rhubarb and Rhubarb, because Undulatum Rhubarb contains rhaponticin as marker compound that is not indicated at Rhubarb. Some of the recently imported Undulatum Rhubarbs have been found to be Rhubarb. Also, it is known that only Undulatum Rhubarb is cultivated at domestic environment. But some plant origins of Rhubarb are grown in Korea, too. Further study are needed to clarify clear origin between Undulatum Rhubarb and Rhubarb. Thus, we collected some domestically cultivated samples and identified them. Methods and Reseults : Rheum undulatum L., Rhubarb, Rheum tanguticum Maximowicz ex Balf. which were cultivated in Gangwondo Agricultural Research and Extension Services in Cheorwon were collected and anayzed the DNA sequences. We also compared DNA sequences in Rhubarb collected from England and R. rhabarbarum L., R. undulatum L., and R. franzenbachii on NCBI. As a result, two kinds of rhubarb cultivated in the test plantation were identified as R. rhabarbarum and R. officinale. In addition, R. undulatum (plant origin of Undulatum Rhubarb) was identified as Rhubarb (Rheum rhabarbarum) in England with 99 - 100% identical in nuclear ITS gene region. Conclusion : R. undulatum, plant origin of Undulatum Rhubarb, is reported as synonym of R. rhabarbarum, R. franzenbachii. Rheum speices which are cultivated as tester in Gangwondo Agricultural Research and Extension Services in Cheorwon are estimated as R. undulatum and R. officinale. Therefore, not only Undulatum Rhubarb but Rhubarb could be grown in Korea.

High intensity focused ultrasound (HIFU) treatment of uterine myoma is a non-invasive procedure that uses high intensity, focused ultrasound to heat and destroy the tissue of uterine myoma. The history of using therapeutic ultrasound dates back to the early 20th century, and since, the technique has been continuously improved to an extent that the breadth of its clinical applications, both diagnostic and therapeutic, justify the integral role it plays in medicine today. HIFU treatment requires that ultrasound beams be focused on targeted uterine myoma. Due to significant energy dissipation at the focus, temperatures within tissues increase to more than 65℃, and destroy diseased tissue. This technology can achieve precise "ablation" of myoma tissue, and because it destroys diseased tissue non-invasively, it is also known as "Non-invasive HIFU surgery". Development of this technology significantly broadened the range of treatment options for patients suffering from uterine myoma. Furthermore, in contrast to surgery, HIFU requires only a short period of hospitalization and has a low complication rate. Today, HIFU is being used more frequently to treat adenomyosis, but its increased use has led to the reporting of more complications. Here, the authors report a case of uterine perforation after HIFU ablation for adenomyosis.

Background : In previous studies, adlay seeds showed a prevalence of diversified fungal flora with the predominant fungal genera being Fusarium (45.6%) and In vitro test showed that fungal toxins like Fumonisin and Zearalenone were produced by Fusarium fujikuroi, F. asiaticum and F. graminearum. Because of this we performed experiments to selecting disinfective chemicals for controlling the Fusarium contamination in the adlay seed. Methods and Results : We carried out the chemical efficacy test such as seed disinfectants selection test appling before planting and pesticides selection test using in the earing season. In the present study, eleven different commercially available seed disinfectant were applied to the adlay seeds. Among 11 seed disinfectants, Hexaconazole+Prochloraz emulsifiable concentrate (EC) and Prochloraz emulsifiable concentrate (EC) had control value of 80% or above against Fusarium species tested. In the pesticides selection test, seven different commercially available pesticides for Fusarium blight (Scab) control were applied and we observed that Metconazole suspension concentrate(SC) strongly inhibited the mycelial growth of 10 Fusarium species all. Conclusion : From the above results, we selected Hexaconazole+Prochloraz EC and Prochloraz EC as a seed disinfectants and Metconazole SC as a pesticide using in the earing season for Scab control.

Background : This experiment was conducted to select GAP applying seed disinfectants in Astragalus membranaceus and Platycodon grandiflorum. Methods and Results : We carried out the chemical efficacy and injury test. For the efficacy test, we investigated fungal detection rate by seed disinfectants and for the chemical injury, we investigated germination rate and emergence rate by seed disinfectants in reference amount and fold amount. These experiments carried out two times. The results obtained are as follows. In the experiment for seed disinfectants selection of Astragalus membranaceus, all tested chemicals such as Tebuconazole emulsifiable concentrate(EC), Thiophanate-methyl + Triflumizole wettable powder(WP), Prochloraz copper chloride complex+Tebuconazole suspension concentrate(SC), Prochloraz emulsifiable concentrate(EC), Fludioxonil wetting liquid(WL) and Hexaconazol+Prochloraz emulsifiable concentrate(EC) had control value of 80% or above against seed contaminated fungi. However two chemicals such as Tebuconazole EC and Prochloraz copper chloride complex+Tebuconazole SC and two chemicals such as Prochloraz EC and Hexaconazol+Prochloraz EC exhibited chemical injury significantly in reference amount and in fold amount respectively, compared to non treated control. In the case of seed disinfectants selection of Platycodon grandiflorum, Prochloraz copper chloride complex+Tebuconazole SC, Prochloraz EC and Hexaconazol+Prochloraz EC had control value of above 80% against seed contaminated fungi except Thiophanate-methyl+Triflumizole WP and Fludioxonil WL. However Hexaconazol+Prochloraz EC and Prochloraz copper chloride complex+Tebuconazole SC exhibited chemical injury significantly in reference amount and in fold amount respectively, compared to non treated control. Conclusion : From the above results, we finally selected three items of seed disinfectants including Thiophanate-methyl+Triflumizole WP and Fludioxonil WL in Astragalus membranaceus and Prochloraz emulsion in Platycodon grandiflorum.

Background : Garlic is one of the important vegetables and a source of natural anti-oxidants. This study was carried out to investigate the antioxidant activities including 2,2-diphenyl-1-picr yl-hydrazil (DPPH), 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS), ferric reducing antioxidant power (FRAP), reducing power (RP) and total polyphenol content (TPC) of A. ampel oprasum L. Methods and Results : DPPH, ABTS, FRAP, TPC, and RP were analyzed the extract of aerial plant part in 22 accessions of A. ampeloprasum by spectrophotometry mathod. A. tuberosum Rottler ex Spreng. was used as a control. DPPH was ranged from 0.35 to 3.06 ㎍ ASC ㎎-1 dw. ABTS and FRAP showed wide variation from 4.37 to 29.30 ㎍ Trolox ㎎-1 dw and 3.18 to 10.8 ㎍ ASC ㎎-1 dw, respectively. RP and TPC were ranged from 3.43 to 9.51 ㎍ GAE ㎎-1 dw, and 0.8 to 18.63 ㎍ ASC ㎎-1 dw, respectively. Cluster analysis of A. ampeloprasum germplasm was divided into two major groups. Group Ⅰ (7 accessions) characterized as higher antioxidant activities than the group Ⅱ (15 accessions) and had similar antioxidant activities with A. tuberosum as a control. FRAP value showed a significant strong positive correlation with DPPH (r = 0.868*) and ABTS activity (r = 0.826*). Principal component analysis showed that the first two principal components (PC1 and PC2) cumulatively explained 85.64 % of total variation. Conclusion : From the above results, we may suggest that A. ampeloprasum aerial parts might have useful as a new material for functional food.

Background : The objective of this study was to investigate antioxidant activities, inhibitory activities against heme induced colonic epithelial cell proliferations, anti-inflammatory activities and anthocyanin profiles in the anthocyanin rich fraction (ARFAM) from fruits of Aronia melanocarpa, where these are considered functional substances and available food coloring agents in Korea. Methods and Results : Anthocyanins were identified by reversed-phase C18 column chromatography and HPLC-DAD-ESI/MS analysis. To compare the antioxidative and anti-inflammatory capacity of Aronia melanocarpa berries, recognized for their high content of anthocyanins, isolation method was developed to obtain high-purity anthocyanins in the extract. Anthocyanin-rich fractions (ARFAM) enriched in anthocyanins were found to be potent strong inhibitory activity towards heme induced colonic epithelial cell proliferations are associated with an increased risk of colon cancer than acidic ethanol extract (AME). The immunomodulation properties were assessed in growth of both human B and T cells, its cytokines secretion such as IL-6 (interleukin-6) and TNF-α (tumor necrosis factor-alpha). AME enhanced interleukin-6 and reduced tumor necrosis factor-a production, whereas ARFAM only had a effect in increasing of IL-6 expression. Conclusion : These results demonstrated that there was no major relationship between the antioxidative and immunomodulation capacities of AME and ARFAM.

Background : Management of air temperature are known to primarily affecting on physiological properties and yield in plant. Methods and Results : The effect of air temperature on characteristics of photosynthesis and chlorophyll fluorescence in Schisandra chinensis Baillon were investigated under controlled temperature using growth chamber. Net photosyntheis rate, transpiration was measured at 1,000 μmol m-2 s-1 of photon flux density and chlorophyll fluorescence was analyzed by OJIP method. Net photosyntheis rate and transpiration rate was higher in treatment of 25℃. As results of chlorophyll fluorescence by OJIP analysis, maximum quantum yield (Fv/Fm) of photosystem II (PSII) and PIabs was higher in treatment of 25℃ which reflects the relative reduction state of PSII. But in treatment of 35℃ the relative activities per reaction center such as ABS/RC, DIo/RC were higher than in treatment of 25℃ which implied that the relative reduction of electron transport at PSI and increasement of photo inhibition at reaction center. Conclusion : This result implies that 25℃ of air temperature may be a adequate temperature to improving the efficiency of photosynthesis through controlling a photosystem in Schisandra chinensis Baillon.

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.

본 연구에서는 비 상품 부추의 산업적 활용의 활성화를 위해 제 2형 당뇨모델인 db/db 마우스에서 부추 추출물과 부추 발효물에 대한 항당뇨 효과를 조사하였다. 부추 발효 물 제조를 위한 균주선발을 위해 L. acidophilus, L. plantarum, L. casei을 접종하여 배양시킨 부추 추출물(부추 발효물)에 대한 전자공여능을 측정한 결과, L. acidophilus, L. plantarum 부추 발효물은 활성이 증가되었으나 L. plantarum 접종한 부추 발효물의 superoxide radical 소거능 은 부추 추출물의 0.6배 수준으로 감소하였다. L. plantarum 와L. casei 균주를 접종한 부추 발효물의 superoxide radical 소거능은 부추 추출물과 유사한 수준을 나타내었다. 따라 서L. plantarum과L. casei를 이용하여 발효한 부추 발효물 과 부추 추출물을 제2형 당뇨질환 동물모델인db/db mice에 두 가지 농도구간으로(저농도 : 200 mg/kg, 고농도 : 400 mg/kg) 경구 투여한 후, 항당뇨 효능을 평가하였다. 체중 및 식이섭취량을 측정한 결과, 저농도 부추 발효물을 투여 하였을 때, 식이섭취량의 변화 없이 체중증가량이 유의적 으로 감소되는 것을 확인할 수 있었다(p<0.05). 혈당증가량 과 혈청 내 insulin 함량은 고농도 부추 추출물을 투여하였을 때, 유의적으로 감소되었고, 부추 발효물을 투여한 군에서 도 감소되는 경향을 나타내었다(p<0.05). 경구 당 부하검사 결과에서도 고농도의 부추 추출물 및 부추 발효물을 투여한 군에서 포도당 내성 효과가 개선되는 것으로 나타났다. 당 뇨병에 의해 감소된 혈청 내 GLP-1 농도는 고농도 부추 추출물 및 고농도의 부추 발효물 투여로 인해 증가되었으며 이상의 결과들은 부추 추출물 및 부추 발효물이 GLP-1 분비 를 증가시켜 insulin 저항성을 개선시킬 수 있음을 나타낸다. 비록 본 연구결과에서 제2형 당뇨질환에 대한 항당뇨 효능 은 부추 추출물이 부추 발효물 보다 더 효과적인 것으로 나타났으나, 두가지 유산균으로 혼합발효한 부추 발효물은 부추 추출물과 유사한 수준의 항당뇨 효능을 보임과 동시에 제2형 당뇨병으로 인한 체중증가도 감소시킬 수 있어 비만 을 동반하는 제2형 당뇨병의 예방과 개선을 위한 기능성 소재로 활용될 수 있을 것이라 사료된다.

Recently there are increasing numbers of people participating in sports activities. Accordingly, the rate of sports injuries is increasing as well. In this light, this study was conducted to investigate the extent of acute damage and its forms by examining the current state of patients with sports injuries. This research study was conducted between January of 2008 and December of 2010 in Chosun University Hospital through retrospective review of the medical records of patients with sportsrelated injuries. The total number of patients with sports injuries who visited the emergency center was 887. The number of male patients was 726 (81.85%), far more than the number of female patients (18.15%). More than half of the patients, accounting for 419 (47.23%), had injuries on their face; second and common parts, in which injuries occurred, were upper and lower body, accounting for 146 (16.45%) and 193 (21.75%), respectively. The majority of patients did not undergo surgical treatment. Only 113 (12.73%) patients underwent surgical treatment. In addition, more than 80% of them were not hospitalized but 170 of them needed to be hospitalized. Most sports injuries occurred in young male patients. This can interrupt participation in sports activities for a long time and result in lower quality of life. Hence proper preventative measures and scientific treatment methods are needed.

We report on a unique case of diffuse large B-cell lymphoma of the cecum, which presented as a subepithelial tumor. A 62- year-old woman with abdominal pain underwent a colonoscopy, resulting in detection of a subepithelial tumor measuring 2 cm in the cecum. We performed a right hemicolectomy with diagnostic and curative intent; histological examination and immunohistochemical staining of the resected tumor indicated a diagnosis of diffuse large B-cell lymphoma. The patient achieved complete remission with combination chemotherapy.

Bacillus thuringiensis(Bt) crystal protein (Cry1Ac) genes encode insecticidal δ-endotoxins that are widely used for the development of insect-resistant crops. Common soybean is a crop of economic and nutritious importance in many parts of the world. Korea soybean variety Kwangan was transformed with Bacillus thuringiensis(Bt) crystal protein genes. We transformed three difference Cry1Ac (Cry1Ac and two modified Cry1Ac) genes into Kwangan using highly efficient soybean transformation system. Transgenic plants with Bt crystal protein genes were confirmed for gene introduction and their expression using PCR, real-time PCR, and RT-PCR. We generated 30 independent lines of transgenic soybean plants. Analysis of the flanking sequences isolated by Inverse PCR revealed complex T-DNA insertion patterns and preferential integration of T-DNA into the intergenic spacer region of the soybean genome. We found 5 different intergenic transgenic soybean lines of soybean genome. Currently, the confirmation of stable gene introduction with Bt genes is also performing by southern blot analysis, physiology test, and agronomic characters are investigating.

Trophoblasts, in the placenta, play a role for placental development as well as implantation in the early pregnancy. The characteristics and functions of trophoblast are identified by their localization and potency for proliferation, differentiation, and invasion. Thus, inadequate trophoblast cell death induces trophoblast dysfunction resulting in abnormal placental development and several gynecological diseases. Recently, it was reported that increased immortalization-upregulated protein-2 (IMUP-2) by hypoxia influences trophoblast apoptosis. However, IMUP-2 function on autophagy, which is type II programmed cell death remains unclear. In this study, we analyzed IMUP-2 expression in trophoblast cells (HTR8-SVneo) and compared IMUP-2 effects on cell death including apoptosis and autophagy in trophoblast regardless of IMUP-2 expression. Increased IMUP-2 in trophoblast by IMUP-2 gene transfection induces cell death, especially, apoptosis increases more than autophagy (p<0.05). However, the decreased IMUP-2 in trophoblasts after siRNA treatment decreased apoptosis with the decreased activities of caspase 3 and 7. The expressions of LC3 and MDC as an autophagosome makers and phosphorylated mTOR, which is a negative regulator for autophagy, increased. In addition, the S phase of cell cycle increased in trophoblasts when IMUP-2 expression decreased. Taken together, the alteration of IMUP-2 can control the balance between apoptosis and autophagy of trophoblasts resulting in functional involvement in placental development and in gynecological diseases by regulating the function of trophoblasts.

Twenty two common millet (Panicum miliaceum L.) varieties collected from Korea, China and Russia were investigated for their phylogenetic relationship using 5S ribosomal DNA sequences with a hope to provide the basic information on their exact origin. Sequences of 5S rDNA were isolated by PCR. The primers, 5s-rRNA1 and 5s-rRNA2, were designed to isolate the complete NTS. Genomic DNA amplification produced two fragments with different length, 900 bp and 400 bp fragments, confirming the presence of two types of 5S rDNA repeats that differed from each other in the length of the NTS region. Amplified DNAs of 400 bp fragment were subcloned and used for further investigation. The obtained NTS sequences ranged from 200 to 300 bp and homology of sequences among plant materials was much higher than long repeat. CLUSTALW multiple aligment of 5S rDNA sequences from 22 different common millets revealed the clear difference by their origin. And critically different areas with insert or deletion were also confirmed. Those sequence difference seems to be used for discrimination of cultivars from different origin and use as molecular markers for origin identification. In phylogenic tree construction, the clear classification was shown where the genotypes from China and Russia is positioned together and stay away from domestic genotypes.
