In 2011, neighborhood parks occupied a total area of 280,135,257㎡ in small and medium sized city areas and this excluded the metropolitan regions. In the rural area, the park area per person(22.64㎡) is larger than the urban area(9.50㎡). It is a questionable why there is a higher park ratio in the rural area compared to the cities, where the function of the neighborhood parks is not being utilized well. But, there are already a lot of parks that has been constructed in the rural areas and a lot of money is being spent in maintaining them. Hence, rather than reducing the number of "country parks", it can be suggested that these "country parks" ought to be utilized in a different manner than the parks in the city. In that point of view, this study examined the issues of the country park usage along with the utilization of the local festivals within the parks. Firstly in this context, this study compared the amount of neighborhood parks between small and medium sized cities and metropolitan areas, and analyzed those results. Secondly, daily newspaper articles were collected and categorized to find the usage of the rural park which were then analyzed. Then, the extraction of the essential points in composing the festival space was carried out. Also, the general design guides of making the neighborhood parks were drawn. Last but not least, using these two resources, this study suggested design guidelines for using neighborhood parks as a Festival Space in small and medium sized cities.

Background: In most solid tumors, the CD34 antigen has not been detected, so positive selection of CD34+ cells may reduce tumor cell contamination and the CD34+ cells are capable of reconstituting hematopoiesis. We tried CD34+ cell transplantation in two patients. Method: CD34+ cells from chemotherapy + G-CSF mobilized PBPCs or bone marrow were positively selected with an avidin-biotin immunoadsorption column (CEPRATE SC system). Case 1. One course of chemotherapy using cyclophosphamide(200㎎/㎡) and etoposide (4.2g/㎡), combined with G-CSF(5㎍/㎏) S.C. was used in a relapsed lymphoma patient. This patient responded to the induction chemotherapy. CD34+ cells from harvested bone marrow were selected by the CellPro immunoadsorption column. The total number of mononuclear cells loaded onto the CellPro was 2.4×10^(8)/㎏, with 1.1% CD34+ cells. After column separation, the total number of positively selected cells was 5.16×10^(6)/㎏. The number of CFU-GM was 76.8×10⁴/㎏. This patient was treated with melphalan (140㎎/㎡) and TBI (1200cGy) and the positively selected CD34+ cells were infused. The time to neutrophil recovery greater than 0.5×10^(9)/L was 19 days and the time to platelet recovery greater than 50×10^(9)/L was 21 days. Case 2. Two courses of mobilizing chemotherapy were given 4 weeks apart using taxol(210㎎/m2) and adriamycin(60㎎/m2), combined with G-CSF(5㎍/㎏) S.C. in a breast cancer patients with 7 axillary node metastasis. CD34+ cells from each single leukapheresis product were selected by the CellPro immunoadsorption column. In the first collection, the total number of nucleated cells was 4.4×10^(8)/kg, with 0.42% CD34+ cells. In the second collection, the total number of nucleated cell was 2.8× 10^(8)/㎏ with 0.43% CD34+ cells. After colum separation, the total numbers of collected cells were 4.0×106/kg and 4.8×10^(6)/kg, the total number of CD34+ cells were 1.2×10^(6)/㎏ and 0.82×10^(6)/㎏. Colonogenic assays of positively selected CD34+ cells gave rise to myeloid erythroid, and multilineage colonies, with a median of 190 CFU-GM, 190 BFU-E, and 164 CFU-GEMM per 1×10³ adsorbed cells, respectively. High-dose chemotherapy with cumulative doses of 40mg/㎡ mitoxantrone, 750mg/㎡ thioptepa, and 1000mg/㎡ carboplatin was administered. Positively selected CD34+ cells were rapidly infused 24 hours after the end of high-dose chemotherapy. The time to neutrophil recovery greater than 0.5×10^(9)/L was 16 days and the time to platelet recovery greater than 50×10^(9)/L was 20 days.

Purpose: The purpose of this study was to assess the effect of a prophylactic cable fixation for prevention of femoral fractures in cementless bipolar hemiarthoplasties. Materials and Methods: Forty-eight cementless bipolar hemiarthroplasties with prophylactic cable fixations on the femur were performed in patients>65 years of age between January 2004 and August 2008 (group 1). The control group which did not undergo prophylactic cable fixation included 48 cases (group 2). The mean age was 75.4 years (group 1) and 73.6 years (group 2). The patients were followed up for an average of 19.1 (group 1) and 18.3 months (group 2). The intra-operative fracture rates were compared. Additionally, operative time, estimated blood loss (EBL), and length of hospital stay were compared. Radiologic assessment for stem stability was performed. Clinical assessment was evaluated by the thigh pain and Jensen`s functional score, and Parker & Palmer`s mobility score. Results: There was no fractures in the cabled group (1), and 4 fractures (8.3%) in the control group (2; p=0.041). The mean operative time was 172 minutes (1) and 162 minutes (2), the EBL was 866 cc (1) and 855 cc (2), and the duration of admission was 36 (1) and 35 days (2), respectively. Radiologically, subsidence was 1.59 mm (1) and 1.67 mm (2). Clinically, one (1) and two (2) thigh pains were recorded and the functional score of Jensen was 2 (1) and 2.2 points (2), and the mobility score of Parker and Palmer was 5.2 (1) and 5.3 points (2), respectively. Conclusion: Prophylactic cable fixation is effective for reducing intra-operative femoral fractures.

설악산국립공원 설악폭포에 위치한 아고산대 침엽수인 분비나무와 잣나무의 수고생장 기간을 조사하기 위해 본 연구를 수행하였다. 조사를 위해 분비나무 고사목 2본(SAPPAND01, 02)과 잣나무 고사목 1본(SAPPPKD03)을 선발하였다. 높이별 수고생장 기간을 조사하기 위해 뿌리와 줄기 경계를 기준으로 높이 0, 10, 20, 30, 40, 50, 60, 80, 100 cm에서 디스크를 채취하여 나이테(이하, 연륜) 분석을 실시하였다. 또한 고사연도 분석을 위해 생육중인 분비나무 15본에서 생장편을 채취하여, 연구지를 대표하는 연륜폭연대기를 작성하였다. 연륜 분석 결과, 분비나무인 SAPPAND01과 02의 생육 기간은 각각 102년(1915-2016)과 97년(1918-2014)이었으며, 잣나무인 SAPPPKD03은 62년(1926-1987)이었다. SAPPAND01과 02의 고사 시기는 각각 2016년 가을-2017년 봄과 2015년 여름-가을이었으며, SAPPPKD03의 고사 시기는 1987년 가을-1988년 봄이었다. 100 cm까지 수고생장을 하는데 소요되는 기간은 SAPPAND01이 41년으로 가장 길었으며, SAPPAND02와 SAPPPKD03은 각각 17년과 18년으로 조사되어 수종보다는 개체 간 차이가 큰 것으로 확인되었다. 하지만, 대상목 모두에서 수고 20 cm 전후까지 생장하는데 소요되는 기간은 공통적으로 긴 것으로 나타났다. 본 결과는 향후 우리나라 아고산대 침엽수 수령조사의 정확성을 향상 시키는데 중요한 기초자료가 될 것이다. This study aimed at investigating the height-growth duration of Abies nephrolepis and Pinus koraiensis which are the tree species growing in the subalpine area at Seorak Falls of the Seoraksan National Park. For the study, two dead Abies nephrolepis (SAPPAND01, 02) and one dead Pinus koraiensis were selected. To investigate the height-growth duration, 9 disks were collected at the height of 0, 10, 20, 30, 40, 50, 60, 80, 100 cm height from the collar to upward from the sample trees, and then their ring-width were measured. The site master chronology used to the reference to date the death years of the sampled trees was established using the increment cores from 15 living Abies nephrolepis. Through the tree-ring analysis, the ages of SAPPAND01 and 02, and SAPPPKD03 were verified 102 (1915-2016), 97 (1918-2014), and 62 years (1926-1987) years, respectively. The death seasons and years of SAPPAND01 and 02, and SAPPPKD03 were autumn in 2016 - spring in 2017, summer - autumn in 2015, and autumn in 1987 and spring in 1988, respectively. The height-growth durations up to 100 cm from the collars of SAPPAND01 and 02 and SAPPPKD03 were -41, 17, and 18 years, respectively, so that it was verified that the height-growth duration was not changing depending on tree species but individual trees. During the juvenile periods growing up to approximately 20 cm from the collar, however, all sample trees showed relatively taking long times. All results obtained from this study would be fundamental data to improve the accuracy of examining the age of conifers in the subalpine areas.

박정욱,정한모,송재철 울산대학교 2000 생활과학논문집 Vol.2 No.1

시차주사열량기와 색도계를 이용하여 Trehalose의 가래떡 노화에 미치는 영향을 검토하였다. 가래떡의 노화정도는 저장온도와 무관하게 경시적으로 증가하였는데 Trehalose가 노화를 억제하는 것으로 나타났다. 특히 저온에서 노화가 실온보다 심하게 일어났으며 저장초기에 저장온도에 대한 영향이 큰 것으로 나타났다. 그리고 L*값은 실온저장(25℃)시 냉장저장(4℃)의 경우보다 시간에 따른 변화가 컸으며, 냉동보관시 a*값은 저장 1일째 까지는 변화가 없다가 5%를 첨가한 가래떡을 실온에서 저장한 경우에는 가장 낮은 a*값을 나타내었다. b*값의 경우에는 Trehalose 첨가량과 저장온도에 따라 크게 변하지 않았다. 색깔안정화의 효과는 Trehalose 첨가농도가 증가할수록 큰 것으로 나타났으며, 특히 냉장보관시에 효과가 두드러지는 것으로 관찰되었다. This studies were investigated to provide the influence of trehalose on retrogradation of Korean rice cake by differential scanning calorimeter and tristimulus values of CIE color Croma Meter. Having no connection with storage temperature, degree of retrogradation of Korean rice cake was increased with storage time. Degree of retrogradation of Korean rice cake was decreased in case of addition of trehalose to the Korean rice cake paste. Degree of retrogradation of Korean rice cake stored at low temperature(4℃) was higher than that of Korean rice cake stored at room temperature(25℃). In particular, degree of retrogradation of Korean rice cake was shown to be clearly influenced by storage temperature at the beginning of storage. The value of L of Korean rice cake at room temperature was indicated to be significantly changed compared with that of Korean rice cake at low temperature. The value of a of Korean rice cake was not changed until one day of storage, and shown to be minimized in storage at room temperature(25℃) in case of addition of 5% trehalose to the paste of Korean rice cake. The change of b value in general was not significantly observed even if storage temperature and amount of trehalose have been variable. However effects of trehalose in color stability of Korean rice cake was remarkably exhibited in storage at low temperature(4℃).

This thesis studied the behavior of tunnels according to the change in the excavation distance during the additional construction of NATM tunnels. The Finite Difference Method was employed to analyze the crown settlement, the horizontal convergence, and the axial force of rock bolts, extending the distance between the tunnels up to five times as long as the diameter of tunnel. It turned out that the crown settlement, the horizontal convergence, and the axial force of rock bolts became decrease as the distance between the tunnels became farther, and that they converged when the distance between the tunnels was over 3D.

저자들은 1981년부터 1990년사이에 64,207명을 대상으로 내시경검사를 시행하여 8,814명에서 소화성궤양을 진단하여 다음과 같은 결론을 얻었다. 소화성궤양의 발생률은 13.7%였다. 위궤양과 십이지장궤양의 발생비는 1981년에는 1:0.9였으나 그후로는 1:1.1-1:1.5로 십이지장궤양의 발생비율이 높았다. 발생비율을 남녀별로 보면 위궤양의 경우에는 약 4:1 십이지장궤양은 3:1로 남자에서 많았다. 연령별로는 위궤양은 40대, 50대, 60대의 순서였고, 십이지장궤양은 30대, 40대, 20대 순으로 호발하였다. 위궤양은 위체부에서 대부분 발생하였다. In this century, very striking changes in incidence and prevalence of peptic ulcers, as well as in sexual proportion, in the age of the affected population and in the proportion of duodenal to gastric ulcers had occured and these epidemiological changes are ongoing. Therefore, we reviewed 8,814 cases with endoscopically proven peptic ulcers from 1981 to 1990. The results obtained are as follows; The prevalence of peptic ulcers among patients received endoscopy was 13.7%. The ratio of peptic ulcers among patients received endoscopy was 13.7%. The ratio of gastric ulcer to duodenal ulcer was 1: 0.9 in 1981, but after then the propotion of duodenal ulcer was higher in 1: 1.1-1:1.5. The ratio of male to female was about 4:1 in gastric ulcer and 3:1 in duodenal ulcer. The prevalence of gastric ulcer was highest in foruth decade and then fifth and sixth in order and the prevalence of duodenal ulcer was highest in thrid decade and then fourth and second decade in order. Most of the gastric ulcers were found at the gastric body.
