  • This study was carried out to investigate the vascular plants of Mt. Choejeong in Gachang-myeon, Daegu. From March 2017 to October 2018, a total of 22 studies were conducted. The vascular plants surveyed were grouped into 560 taxa, including 104 families, 297 genera, 495 species, 4 subspecies, 51 varieties and 10 forma. Endemic plants 15 taxa, Rare plants 5 taxa, Red list plants 5 taxa, Floristic regional indicator plants 54 taxa, Naturalized plants 36 taxa were recorded. Among surveyed 560 taxa, edible, medicinal, ornamental, timber, pasturing, industrial and fiber plants included 246 taxa (29.2%), 228 taxa (27.1%), 164 taxa (19.5%), 61 taxa (7.2%), 13 taxa (1.5%), and 8 taxa (0.9%). And because people are coming and going more frequently than in the past, this will result in more frequent influx of naturalized plants and a threat to the habitat of the plants that are currently growing.

  • This study was conducted to investigate the effect of stem node number, pinching time and growth retardants on the growth of Coreopsis spp. and Dianthus spp. Thy day of seedings are not passed period of 4 weeks after seedlings in the Cutting number and the days seedlings of joint experiments of Coreopsis spp. 2 node ranches treatment of Coreopsis spp. are reasonable valuable as ornamental pot product. Pinching time of Coreopsis spp. was more effectiveis on lateral and growth inhibition in the two times pinching treatment. It is observed that plant growth inhibitors was affected the growth of Coreopsis spp. It is observed that B-9 treatment is the effective plants growth and differentiation, especially the 2 times treatment with 4,000 ppm was the most effective. On the other hand, CCC treatment showed significant differences. B-9 treatment of Coreopsis spp was more effectived than the other treatment. Pinching and plant growth inhibitors of Dianthus spp. was not good the growth and plant height. Compared with B-9 4,000 ppm 2 times and control increased leaves extremely. it confirmed that the things are positively affective.

  • The number of patients with coronary artery disease and peripheral vascular disease are increasing, and the need of small diameter vessel is also increasing. We developed small diameter artificial vessel and experimented in vivo. We got allogenic valve from mongrel dogs, and removed all cells from the allogenic valve. Then, we seeded autologous bone marrow cells onto the decellularized scaffold. After implantation of artificial vessel into the canine carotid artery, we performed angiography regularly. In case of vessel occlusion or at 8 weeks after operation, we euthanized dogs, and retrieved the implanted artificial vessels. Control vessels were all occluded except one (which developed aneurysmal dilatation). But autologous cell seeded vascular graft were patent by 4 weeks in one, by 6 in one and by 8 weeks in two. Histologic examination of patent vessel revealed similar structure to native artery. Tissue-engineered vascular graft manufactured with decellularized allogenic matrix and autologous bone marrow cells showed that tissue engineered graft had similar structure to native artery.

  • Image fusion is fast catching attention as Wagner pointed out in his 2006 version of the recent progress and development presented at the annual meeting of Society of Nuclear Medicine. Prototypical fusion of bone scan and radiograph was already attempted at in 1961 when Fleming et al. published an article on strontium-85 bone scan. They simply superimposed dot scan on radiograph enabling simultaneous assessment of altered bone metabolism and local bone anatomy. Indeed the parallel reading of images of bone scan and radiography, CT, MRI or ultrasonography has been practiced in nuclear medicine long since. It is fortunate that recent development of computer science and technology along with the availability of refined CT and SPECT machines has permitted us to open a new avenue to digitally produce precise fusion image so that they can readily be read, exchanged and disseminated using internet. Ten years ago fusion was performed using Bresstrahlung SPECT/CT and it is now achievable by PET/CT and SPECT/CT software and SPECT/CT hardware. The merit of image fusion is its feasibility of reliable assessment of morphological and metabolic change. It is now applicable not only to stationary organs such as brain and skeleton but also to moving organs such as the heart, lung and stomach. Recently, we could create useful fusion image of cardiac SPECT and 64-channel CT angiograph. The former provided myocardial metabolic profile and the latter vascular narrowing in two patients with coronary artery stenosis and myocardial ischemia. Arterial stenosis was severe in Case 1 and mild in Case 2.

  • Kawasaki disease is generally diagnosed base on its clinical features. Sometimes unusual or atypical presentations make the diagnosis of Kawasaki disease difficult. We experienced an unusual case of Kawasaki disease presented with unilateral parotitis in a 23-month old girl. Despite of intravenous antibiotics treatment, fever and unilateral parotid swelling persisted. Skin rashes, conjunctival injections, and coronary abnormalities showed up on the 8th day of fever. After the intravenous immunoglobulin and salicylates treatment, all symptoms disappeared. Although unilateral parotitis is very unusual presentation of Kawasaki disease, in case of no response to antibiotics, Kawasaki disease should be included in the differential diagnosis.

  • The purpose of this reserch is to investigate the flora of Dumi Island. This island locates at $128^{\circ}$ 13' E. longitude and $34^{\circ}$ 41' N. latitude. As a result of our investigation, the distribution of plants on Dumi Island could be summarized as follows. The vascular plants through this investigation were 66 families, 121 genera, 127 species, 16 varieties, 2 forma, and 145 kinds. From 1945 to 1960, most Pinus densiflora and Quercus mongolica were cut and sent as fuel to the cities of Masan, Chungmu and Samchunpo. After these deforestation years, there was a change of policy in the area and then wood was substituted by coal blacks as fuel and along with this occurs reforestation. Because of the reforestation by the present administration and natural means of suctrees, Castamopsis cuspidata var. thunbergii, Camellia japonica and Machilus japonica; they were found to exist near Sheonangdang in the northern region at Hakli and at Kuchun in the south. In the central part of the island at Mt. Chunhwang there are slopes of 20-30 degrees which are cultivated by the islanders this mountain which can be cultivated and 65% or 830 islanders are farming this land. Although this 125.4 hectors is not a large portion, this mountain with its variety of growth at different elevations, seems to be very fertile causing thick growth at any level.

  • Renovascular hypertension results from a lesion that impairs blood flow to a part of or all, of one or both kidneys. Renal artery stenosis is the major cause of renovascular hypertension and the most common cause of treatable secondary hypertension. Recently, percutaneous transluminal renal angioplasty(PTRA) with or without stent placement, has become the preferred choice for correcting symptomatic renal artery stenosis since it is less invasive than surgical reconstruction. PTRA with balloons designed for the dilatation for the dilatation of the coronary artery can be tried in small sized renal artery stenosis. We report a case of renovascular hypertension in a 13-year-old male who had small sized renal artery stenosis. Hypertension was controlled by PTRA with balloon dilatation.

  • This study is to analyze the impedance response in human body by acoustic stimulation on acupoints and contrast parte; for objectification of the meridian substance. It is to verify meridian pathway and channel theory or bio-energy in body. This paper proposes to make an hypothesis about the underground water theory. The meridian has not tube or pipe line type channel but bio-energy flow along the channel similar to flowing pattern of underground water in body. It was analyzed the current characteristic or impedance response after acoustic stimulation by sound wave of 5 specific tones. The response characteristics of current stimulation are measured by the average current magnitude and variation ratio or meridian. The current variation ratio or Live Meridian(gung) 33.2%, Heart Meridian(sang) 30.7% Kidney Meridian (gak) 33.1%, Spleen Meridian(chi) 33.9%, Lung Meridian (wo) 30.7% are to be compared to contrast parts (non-acupoint and meridian). In experimental results, meridian is discrimination to non-meridian, and 5 vital meridians have a reciprocal relationship with sound wave of 5 specific tones.

  • Because Lysimachia mauritiana is not able to maintain the seed viablity for a long time, it has difficulties in using for the ornamental plants or landscape gardening. This study was conducted to elucidate the optimal germination conditions of Lysimachia mauritiana seeds. The germination rate of the seeds was higer in light condition than in dark one. In experment determining the proper germination temperature, the germination rates were 2.2%, 96.9% and 91.2% under 35$\circ $C, 25$\circ $C, and 20$\circ $C, respectively in light condition. The approprate temperature for the germination was 25$\circ $C in light. The decreases of germination rate with the increase of the preservation periods was able to recover by priming pretreated with NaCl solution and KNO$_{3}$ + K$_{3}$H$_{2}$PO mixed solutions. When the storage period was 300 days, the germination rate was 75% without priming treatments. But the seeds primed with NaCl 0.1M and KNO$_{3}$ + K$_{3}$H$_{2}$PO mixed solutions 0.1M, showed germination rate above 90%. T$_{50}$ also was shorten from 5.25 without priming to 3.78 with NaCl 0.1M. Seed priming may induce earlier sprouts and increase germination rate of long-preserved seeds of native wild plants.

  • In order to diagnose cardiovascular disease, we proposed EP-based(emerging pattern- based) classification technique using multi-parametric diagnosis indexes. We analyzed linear/nonlinear features of HRV for three recumbent postures and extracted four diagnosis indexes from ST-segments to apply the multi-parametric diagnosis indexes. In this paper, classification model using essential emerging patterns for diagnosing disease was applied. This classification technique discovers disease patterns of patient group and these emerging patterns are frequent in patients with cardiovascular disease but are not frequent in the normal group. To evaluate proposed classification algorithm, 120 patients with AP (angina pectrois), 13 patients with ACS(acute coronary syndrome) and 128 normal people data were used. As a result of classification, when multi-parametric indexes were used, the percent accuracy in classifying three groups was turned out to be about 88.3%.
