This study was performed with the aim to ultimately seek administrative activation of the future private recreational forest by presenting a plan for introducing the green tourism into the above forest. The green tourism and the management of the private recreational forest appear to be oriented toward the common goal in terms of securing the sustain ability of nature environment and pursuing the income increase at the same time. Accordingly, the above plan will be very convincing in that the green tourism is introduced in order to overcome the difficulty in managing the private recreational forest. As a result of the study, it is considered that the link of the green tourism with the forest recreation may allow for : meeting the demand for the green tourism by urban people; increasing the income of the manager of the private recreational forest ; and preventing any unplanned forest development due to the difficulty of management. By doing so, it will ultimately be possible to produce the synergy effect that can efficiently utilize and manage forests. Accordingly, as a specific plan for introducing the green tourism into the private recreational forest, the study has recommended to : raise the flexibility of the administrative structure ; develop and operate differentiated programs; establish networks with communities ; continue the exchange and cooperation between urban regions and mountain regions ; and grow and maintain forests for improving their recreational function.

본 연구는 경기도 포천시 화현면 소재 국유림을 대상으로 지리정보시스템에 의하여 도시림 휴양공간의 적지로 평가되는 입지를 선정함으로써, 향후 도시림 휴양공간 조성을 위한 적지평가에 GIS 기법을 도입하는 방안을 모색하는데 목적을 두고 수행하였다. 도시림 휴양공간 적지를 평가하기 위한 인자로 영급, 임상, 소밀도, 임종, 수계(계곡), 경사, 표고 및 도로접근성 등 8인자를 선정하고, 인자별 점수 및 중요도를 고려한 가중치를 부여하여 최적지를 분석하였다. 이와 같이 도시림 휴양공간 적지평가을 위해 GIS기법을 활용함으로써 식생 인자, 입지 인자 및 접근성 인자 등을 고려하여 합리적이고 효율적으로 적지를 선정할 수 있었다. 다만, 도시림 휴양공간 조성을 위해서는 도시림이라는 공간적 특수성을 고려한 사회 · 경제적 인자의 검토가 요구되는 바, 향후 적지평가를 위해서는 이에 대한 선행검토가 있어야 할 것으로 판단된다. This study was carried out to evaluate the suitable area for recreational region in urban forests at Pocheon City in Gyeonggi Province using GIS technique. The eight factor made a selection of evaluating the suitable area for recreational region in urban forests, that is, age c1ass, forest cover type, crown density, water, slope, altitude and the accessibility from road. And the final suitable region was analyzed to give a score by the factor and the weight. The results showed that it was suitable technique for GIS that evaluate the recreational function by regarding for biological, geomorphological and accessibility factor. But, it was required that previously investigate the social and economic factors that related with the characteristics of urban area.

본 연구는 자연휴양림과 수목원 간의 방문 이용특성과 서비스 만족도, 전반적 만족도 및 충성도(재방문의향, 권유의향)의 관계를 비교, 분석하는 것을 목적으로 수행하였으며 주요 결과는 다음과 같다. 첫째, 자연휴양림의 서비스 만족도, 전반적 만족도, 이용객 충성도 모두 수목원보다 높게 나타났으며, 상대적으로 서비스 만족도가 전반적 만족도나 이용객 충성도에 비해 평균 차이가 큰 것으로 분석되었다. 둘째, 자연휴양림의 서비스 만족도는 전반적 만족도, 이용객 충성도에 영향을 주지 않는 반면, 수목원의 서비스 만족도는 전반적 만족도와 이용객 충성도에 정(+)의 상관관계가 있는 것으로 나타났다. 수목원 이용객의 전반적 만족도에 미치는 가장 큰 요인은 ‘산림 및 휴양경관’이었으며 재방문의향은 ‘자연경관 체험콘텐츠’와 ‘시설이용요금’이, 권유의향은 ‘자연경관 체험콘텐츠’가 가장 큰 영향을 미치는 인자로 도출되었다. 본 연구는 전국에 분포한 자연휴양림과 수목원 방문 이용객을 대상으로 공통된 항목을 동시에 조사한 자료를 토대로 분석하여 두 산림휴양공간 간에 이용특성에 차이가 있음을 확인하였다는데 의미가 있다. 향후 이러한 전국 규모의 이용객 실태조사 결과가 산림휴양공간 유형별 차별화된 운영전략 제시로 이어지기 위해서는 산림휴양공간에서 제공하는 서비스 전반을 아우르는 공통 조사항목의 개발이 필요하다. 더불어 각각의 산림휴양공간의 조성목적에 부합하는 기능 발휘를 위해 서비스 콘텐츠를 선택적으로 운영하고 있으므로 해당 항목을 추가적으로 개발, 모듈화하여 공통 조사항목과 병행 조사하는 것이 바람직할 것으로 판단된다. This study was conducted with the aim of comparing and analyzing the relationship between visitors' characteristics and service satisfaction, overall satisfaction and loyalty (revisit intention, recommendation intention) of recreational forests and arboretums. The main results are as follows. First, the scores given for service satisfaction, overall satisfaction, and loyalty of the users of the recreational forests were all higher than those given by the visitors to arboretums, and the service satisfaction level was relatively different from that of the overall satisfaction level or loyalty of the users. Second, the service satisfaction level of the recreational forests did not affect the overall satisfaction level and visitor loyalty, whereas the service satisfaction level of the arboretum was found to be positively correlated with the overall satisfaction level and visitor loyalty. The results are meaningful given that the visitors to recreational forests and arboretums are distributed throughout the country; thus, we confirmed that there are differences in visitor characteristics between the two types of forest recreation areas. In order to differentiate operation strategies for each type of forest recreation areas, the development of common survey items covering the entire set of services provided by forest recreation areas is needed. In addition, it would be advantageous to further develop and modularize the relevant items and conduct surveys in parallel with common survey items, as the service contents are operated selectively to function in accordance with the purpose of creating each forest recreation area.

The aim of this study is the detection of atherosclerosis by using radiolabeled small peptides via non-invasive nuclear imaging. A small peptide, which shows high binding affinity for atherosclerotic lesions in vessels (AP), was synthesized by using a standard Fmoc method and diethylenetriaminepentaacetic acid (DTPA) or tyrosine was conjugated at the N-terminal of the AP to provide DTPA-AP-CC or Y-AP, respectively. The prepared peptide was labeled by 99mTc, 111In or 123I. The labeled peptides were injected into atherosclerosis-induced mice (LDLr(-/-) knockout mice) and control mice via the tail vein. At 15 min post injection, the aortas of the LDLr(-/-) knockout and control mice were excised for an autoradiogram study. Gamma scintigraphic images were obtained at 30 min and 1 h. The optimized labeling yield of [99mTc]DTPA-AP-CC, [111In]DTPA-AP-CC and [123I]Y-AP was over 35%, 100% and over 20%, respectively. Autoradiographic studies showed that the aorta uptakes of [99mTc]DTPA-AP-CC and [111In]DTPA-AP-CC in the LDLr(-/-) knockout mice were much higher than the corresponding uptakes in the control mice. In contrast, the aorta uptake of [123I]Y-AP in LDLr(-/-) and normal mice were comparable. Scintigraphic images, however, did not show any noticeable uptake differences between the LDLr(-/-) knockout and the control mice, which is mostly due to the high background in the abdominal region and to the non-sufficient resolution of gamma camera imaging for the aorta of the mice.

Rhee, Young Sun,Yun, Young Ho,Park, Sohee,Shin, Dong Ok,Lee, Kwang Mi,Yoo, Han Jin,Kim, Jeong Hwa,Kim, Soon Ok,Lee, Ran,Lee, Youn Ok,Kim, Nam Shin Grune Stratton ; American Society of Clinical Onco 2008 Journal of clinical oncology Vol.26 No.36

<P>PURPOSE: The purpose of this study was to explore the prevalence of and to identify the predictors of depression in family caregivers of cancer patients. PATIENTS AND METHODS: We enrolled 310 caregivers of cancer patients from the National Cancer Center, Korea, on this study and obtained demographic information for both patients and caregivers. To assess caregiver depression and its predictors, we used the Beck Depression Inventory (BDI), the Caregiver Quality of Life Index-Cancer, and the Family Impact Questionnaire. We used logistic regression analysis to identify independent predictors of caregiver depression. RESULTS: The majority (67%) of caregivers had high depression scores (BDI > 13), and 35% had very high depression scores (BDI > 21). In a multiple logistic regression model, caregivers who were women, the spouse of the patient, in poor health, feeling burdened, adapting poorly, unable to function normally, or caring for a patient with poor Eastern Cooperative Oncology Group performance status were more likely to experience depression (P < .01 for all values). CONCLUSION: Depression was highly prevalent among cancer patient family caregivers, and care burden was its best predictor. Interventions aimed at reducing the psychiatric effects of cancer should focus not only on the patient but also on the caregiver.</P>

Background: Interleukin (IL)-33 is a member of IL-1 family, released from epithelial cells to modulate innate immune response in COPD after external stimulation. The association between IL-33 and acute exacerbation had not been evaluated. Methods: Korean COPD subgroup study database was used. Serum IL-33 was measured in 497 patients, sampled at initial visit. Clinical characteristics and initial lung function test results were reviewed. Moreover, we evaluated 22 paraffin-embedded archival lung tissue samples stored at St Mary’s hospital by IL-33 immunohistochemical stain. Results: Among the patients, 95% were male and mean post-bronchodilator FEV1 (%) was 69.3±5.4. Majority (81.5%) of the patients were GOLD group 1 or 2. Fifty-one (10.2%) patients had acute exacerbations in the clinic in the last 12 months. Median serum IL-33 level was 580 (140-32,124) pg/mL and the first quartile value was 2,656 mg/mL. We set cut-off value of serum IL-33 to the first quartile level and compared. Among the 497 patients, 26.6% had elevated IL-33 expression. They had more smoking history over 5 packyears (P = 0.05), lower BMI (22.9 vs. 23.5, P = 0.02), higher mMRC grade score (1.16 vs. 1.01, P = 0.05), lower FEV1(66.7% vs. 71.6%, P = 0.03), FEV1/FVC ratio (52% vs. 56%, P = 0.01), FEF 25-75% (28.7% vs. 33.8%, P < 0.05), FeNO (20.3 vs. 30.7, P < 0.05) and higher RV/TLC (41.0% vs. 37.8%, P = 0.01). In addition, elevated serum IL-33 was correlated with previous acute exacerbation history (OR 2.1 (1.16-3.84), P = 0.02). There was no statistical association between serum IL-33 and peripheral eosinophil counts. Tissue IL-33 stained area showed positive correlation with RV (%) (r= 0.37, P = 0.02). Conclusions: Patients with higher serum IL-33 expression had a higher smoking history, decreased lung function and severe airflow obstruction. Previous acute exacerbation history was also associated.

Purpose: This study was designed to evaluate the effect of chronic bronchitis symptoms and degree of emphysema in a multicenter, observational, Korean cohort. Methods: From August 2005 to May 2015, patients diagnosed with COPD who were aged above 40 years at 46 hospitals throughout Korea were enrolled. All of the patients were classified according to chronic bronchitis symptoms and the diffusing capacity of the lung for carbon monoxide (DLCO); demographic data, symptom scores, and the result of lung function tests and exacerbation risks were then analyzed. Results: A total of 812 patients were enrolled. Their mean age was 71.6 years, and 92.7% were male. Among these patients, 285 (35.1%) had chronic bronchitis symptoms. A total of 51% of patients had high DLCO without chronic bronchitis symptoms (CB (-) High DLCO), 24.9% had chronic bronchitis symptoms only (CB (+) High DLCO), 14.2% had low DLCO only (CB (+) Low DLCO), and 10.2% had both low DLCO and chronic bronchitis (CB (+) Low DLCO). Patients with CB (+) Low DLCO showed a significantly lower post-bronchodilator forced expiratory volume for 1 second (FEV1) and more severe dyspnea than patients with CB (-) High DLCO. On multivariate analysis, the risk of acute exacerbation was two times higher in the CB (+) Low DLCO group than in the CB (-) High DLCO group. Discussion: In this COPD cohort, patients showed distinct clinical characteristics and outcomes to the presence of chronic bronchitis and degree of DLCO. CB and low DLCO were associated with the risk of acute exacerbation during the follow-up periods.
