This study was carried out to investigate the status and development direction of horse riding industry for rural development of Korea. Library research and field survey were conducted to collect relevant data such as number of horse and size of horse farms, facilities for horse riding and educational institutions for youths and farmers and the results obtained were as follows : Only a few institutions among high schools, colleges and universities were observed to deliver horse riding programs. For farmers, no equestrian specialist was available in agricultural extension offices. Horse meat is consumed mostly in Jeju Island in Korea. Relevant institutions should be also strengthened including formal and nonformal education for horse riding and much more schools and universities should adopt horse riding program for the training of youths and farmers. Considering the obesity problem, the nutritional composition of horse meat is better than those of pork or beef, so promotion of horse meat consumption also should be strengthened.

In this paper, we evaluate the effectiveness of mechanical horseback riding exercise training for cardiopulmonary responses in 26 healthy adults (male 14, female 12) and suggest its clinical applicability. Exercise was performed using a mechanical horseback riding machine, JOBA(R) (Panasonic Electric Works, Osaka, Japan) and riding movement speed was increased from level 2 (0.73Hz), to 4 (0.9Hz), to 6 (1.03Hz), to 8 (1.2Hz), to 9 (1.3Hz) and maintained 3minutes in each level. Heart rate, blood pressure, maximum oxygen consumption (VO2max) were measured by respiratory gas analysis system (TruOne 2400, Parvo Medics, USA) and exercise tolerance test system(Q Stress, Cardiac Science, USA). To measure exercise intensity, metabolic equivalent (MET) were measured and percent of Heart rate reserve (%HRR), percent of peak heart rate (%peak HR) and calorie consumption were calculated. The results were analysed by SPSS 18.0. We found that the exercise intensity of mechanical horseback riding exercise using JOBA(R) for 15 minutes is moderate in healthy adult who received pre-training.

Pollen morphological characteristics of 7 taxa of the genus Aruncus L. (Rosaceae) were examined using scanning electron microscopy (SEM) to evaluate the taxonomic implication within the genus. Aruncus pollen grains were monad, tri-colporate with granular membranes, small in size ($P=8.33-12.57{\mu}m$, $E=8.93-14.40{\mu}m$), amb is sub-circular to circular, suboblate to prolate-spheroidal in shape (P/E = 0.68-1.70). The sexine ornamentation in all studied taxa was basically striate but existence of perforation (striate-perforate: A. dioicus, A. dioicus var. acuminatus, A. dioicus var. astilboides, A. dioicus var. pubescens, A. dioicus var. vulgaris; striate-pstilate: A. dioicus var. aethusifolius, A. gombalanus) and the widths of muri and grooves varied according to the taxa. In particular, relatively short, and sharply crested muri being a distinct feature of A. dioicus var. acuminatus. As a result, the various combination of each pollen characteristics could be useful to identify the some taxa of the genus Aruncus.

눈개승마 (Aruncus dioicus)는 장미과(Rosaceae) 눈개승마속(Aruncus)에 속하는 다년생 초본식물로 울릉도에서 자생하는 잎줄기 채소이다. 독특한 향기가 특징이며, 인삼맛, 두릅맛, 고기맛이 나는 산채로 세가지 맛이 난다고 하여 예로부터 삼나물로도 불러왔다. 눈개승마에는 caffeic acid, 1-O-Caffeoyl-β-D-glucopyranose 등의 항산화 성분이 다량 함유되어 있으며, 전초는 해독, 편도선염에 효과가 있어 약용으로 쓰이고 어린순은 탄수화물과 무기물 함량이 풍부하다. 비지는 대두를 이용하여 두부를 제조하는 과정에서 발생되는 것으로서 대두로부터 수용성 단백질이 추출되었지만 나머지 약 23%의 단백질, 57%의 식이섬유와 이소플라본 등의 유용한 성분을 다량 포함하고 있다. 또한 비지의 단백질은 다른 식품에는 부족한 황 함유 아미노산과 리신의 함량이 비교적 많고, 두부에 거의 없는 식이섬유가 다량 함유된 고 식이섬유 소재이다. 그리하여, 이러한 콩비지를 고부가가치 식품 소재로 활용하기 위해 건조 미세분말 비지를 제조하고, 이를 산채와의 혼합 가공을 통한 기능증진 효과를 연구하였다. 일반적으로 산채는 쓴맛 제거와 보관성 증진을 위해 데침공정을 주로 하나 산채를 물에 데칠 경우 산채의 유용성분이 대부분 손실된다. 눈개승마의 경우 유용성분이 17.25%, 그 중 폴리페놀 성분이 약 90% 손실된다. 본 연구에서는 기존의 데침공정 대신 찜공정을 이용하여 산채의 유용성분을 보존하고 콩비지를 첨가하여 산채 유용성분의 생이용성 증진 효과를 연구하였다. 눈개승마를 콩비지와 혼합하여 고온고압 가공함으로써 산채의 쓴맛을 줄이고 보관성을 높이는 동시에 눈개승마 폴리페놀의 단량체화를 통해 눈개승마 단독가공에 비하여, 단량체 비율이 약 100~200배 증가하는 것을 확인하였다. 본 연구를 통하여 콩비지의 고부가가치 소재로의 가능성을 확인하였을 뿐만 아니라 산채의 다이어트·건강기능식품 소재로의 산업화에도 기여할 수 있을 것으로 기대된다.

The purpose of this study was to determine the effect of mechanical horseback riding training on trunk control, balance function in stroke patients. 15 stroke patients were recruited for this study. The subjects were randomly assigned to two groups: experimental(n=7) and control(n=8). All subjects received a routine physical therapy. The mechanical horseback riding training was for 30 min in the case of the EG subjects. This study was carried out approximately 8 weeks from March 4 to May 3. The assessment tools of this study involved the trunk control test, postural assessment scale for stroke, Berg balance scale and timed up and go test. The measurements were recorded before the intervention and after the intervention. In the cases of the EG subjects and CG subjects, the variables measured after the intervention significantly differed from trunk control test, postural assessment scale for stroke, Berg balance scale and timed up and go test before the intervention (p<.05). Also, there were significant differences in trunk control test, postural assessment scale for stroke, Berg balance scale and timed up and go test at post test between the 2 groups (p<.05). The findings indicate that mechanical horseback riding training exerts a positive effect on trunk control, balance function in stroke patients. Further studies are required to generalize the result of this study.

The oriental traditional medicine, Aruncus dioicus var kamtschaticus (ADK) is used for hemostasis (blood stopping) and the promotion of blood circulation. Recently, the demands of the aerial part of ADK as edible mountain herbs are rapidly increased due to its unique fragrance and bioactivity. In this study, to evaluate the anti-thrombosis activity of ADK, ethanol extract and organic solvent fractions were prepared from aerial parts of ADK, and their anticoagulation and anti-platelet aggregation activities were determined. In an anticoagulation activity assay, the ethanol extract of ADK increased the thrombin time, prothrombin time, and activated partial thromboplastin time (aPTT) 1.4-2.3 times at a concentration of 5 mg/ml. Among the fractions, the ethylacetate fraction showed strong inhibitory effects against blood clotting factors, as shown in an extension of the aPTT. In contrast, the butanol fraction strongly promoted blood clotting. In an anti-platelet aggregation assay, the activity of the ethanol extract was comparable to that of aspirin, a commercial anti-platelet aggregation agent, and the butanol fraction showed 2-fold higher aggregation inhibitory activity than aspirin. The aforementioned ethanol extract and active fractions have ignorable hemolytic activity against human red blood cells up to a concentration of 0.5 mg/ml. Considering the high content of total polyphenol, total flavonoid, and total sugar of the ethylacetate and butanol fractions, the purified active substances have potential as safe and novel anti-thrombosis agents. This report provides the first evidence of anti-thrombosis activity of ADK.

Actein is the well-known active ingredient of Cimicifugae rhizoma (Black cohosh). In this study, we investigated and compared the binding affinity of tubocurarine, actein, and actein derivatives on the B&C domain of the acetylcholine binding protein through in silico computational docking studies. The three-dimensional crystallographic structure of the acetylcholine binding protein B&C domain was obtained from the PDB database (PDB ID: 2XYT). An in silico computational autodocking analysis was performed using PyRx, Autodock Vina, Discovery Studio Version 4.5, and NX-QuickPharm based on scoring functions. The actein showed an optimum binding affinity (docking energy), with the acetylcholine binding protein at -10.50 kcal/mol as compared to the tubocurarine (-9.80 kcal/mol). The interacting amino acids tryptophan 84 and tryptophan 147, in the B domain of the acetylcholine binding protein active site, significantly interacted with the actein and 27-deoxyactein, and (26R)-actein. The centroid XYZ grid position of the tubocurarine was X=38.300689, Y=112.053467, and Z=51.991022, but the actein and its derivatives showed values around X=26.4, Y=127.3, Z=43.7. These results clearly indicated that actein and its derivatives could be a more potent antagonist to the acetylcholine binding protein than tubocurarine. Therefore, the extract of Cimicifugae rhizoma or actein containing biomaterials can substitute for the botulinum toxin-mediated acetylcholine receptor regulation, and be applied to the anti-wrinkle cosmetics industry.

This study was conducted to investigate the effect of atmosphere-leaf vapor pressure deficit (VPD) in Heracleum moellendorffii and Aruncus dioicus var. kamtschaticus. The VPD was rapidly increased with increasing temperature and decreasing relative humidity. Taken as a whole, the stomatal transpiration reaction was slightly late with increasing of VPD. Maximum photosynthetic rate at high-VPD condition was 6.49 µmol CO₂·m^-2·s^-1 in Heracleum moellendorffii Hance, which was a little lower than 5.57 µmol CO₂·m^-2·s^-1 in Aruncus dioicus var. kamtschaticus, respectively. After 2 p.m, stomatal transpiration of Heracleum moellendorffii at the high VPD condition was rapidly decreased. The results indicated that physiological activities in Heracleum moellendorffii are more limited from high VPD conditions.
