Won, Hyun Kyu,Jeon, Hyon Sun,Han, Hee,Lee, Seung Jung,Jung, Byung Heon Institute of Forest Science 2017 Journal of Forest Science Vol.33 No.4

This study was aimed to analyze the increased forestry incomes by combining timber production and wood processing, which is one of 6th industrialization types in Korean forestry. The selected household has been engaged in forestry for two generations and they produce timber and associated wood products in their own facility. The wood products include dimension lumber, interior wood material, cutting board, and cube chips, the household also utilize logging and sawmill residues as well as seed and seedlings as by-products. Incomes and expenses that have been incurred on individual processes of the sequential timber production and wood processing were surveyed, and we analyzed the economic outcomes of entire business. The results of this study indicate that the gross income of the household is 122.3 million Korean won and the net income is 93.6 million Korean won. The net income of the household is approximately 2.8 times higher than the average net income of whole households in the forestry of Korea in 2016, which is approximately 4.3 times higher than that of households that have been particularly engaged in timber production over the country. We found that the 6th industrialization by combining the two sequential processes creates approximately 3.2 times as much added value compared to the case relying on timber production only.

Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

최근 기후변화로 지난 2009년과 2012년에 강원도 태백시에서는 가뭄으로 인하여 엄청난 피해를 경험한 적이 있다. 또한 가뭄과 장마의 예측은 점점 더 어려워져 가는 실정이다. 특히 태백시의 87일간의 가뭄과 제한급수에 따른 피해액은 일상생활 134억원, 산업부문 338억원, 공공부문 47억원, 정신적ㆍ사회적 피해 1, 430억원 등 총 1, 949억원에 달하는 것으로 분석되었다. 태백시에 또 다른 큰 문제점은 가뭄으로 인한 고랭지 농업 피해로 인한 손실이다. 고랭지 배추를 생산하는 태백시는 우리나라 유일의 고산지역의 도시로서, 고랭지 농업이 특히 발달한 지역이다. 특히 태백 고랭지 배추는 태백시 농산품의 95.9%, 총 경지면적의 86.6%를 차지하고 있으므로, 배추의 생산성이 태백시 농산품 생산성을 대변한다고 할 수 있다. 본 연구에서는 태백시의 공공기관과 고랭지 농업 지역을 직접 방문하여 소규모 빗물 이용 시설에 대한 현황조사 및 시설의 상태를 점검하고 가뭄발생시 고랭지 농업지역의 피해를 최소화 할 수 있도록 소규모 빗물 이용 시설의 적용 방안 및 효과를 분석하였다. Recently, drought and rainy season are getting more serious. It is getting hard to forecast about drought because drought frequency is getting shorter than before. In 2009(winter) and 2012(summer), Taebaek-si was suffered from enormous damage due to the drought. Particularly, in 2009, cost of damage due to drought and restriction on water supply for 87days were estimated daily life sector 134 billion won, industry sector 338 billion won, the public sector 47 billion won, mental and social damage 1, 430 billion won. The other big issue of Taebaek is decrease in products of Highland Agricultural caused by the drought. Highland chinese cabbage which is the most important agricultural product in Taebaek-si account for 95.9% of all agricultural production of Taebaek-si and account for 86.6% of all gross area. For this reason, chinese cabbage of Taebaek-si is tropical agricultural product and is in charge of supply cabbage definitely. It is considered that if small scale rainwater harvesting system would be installed in highland agriculture area, it could reduce damage of drought at low cost and damage of cabbage would be decrease by system. For this study, We have researched regarding current status of Small Scale Rainwater Harvesting System of Highland Agriculture area in Taebaek-si and have compared with the amount of damage and installation cost in case of drought for the beneficial effects of Small Scale Rainwater Harvesting System, flexible supply of water and damage minimization of agricultural products.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Sheet metal forming process is a non-linearity problem which is affected by various process variables, such as geometric shape of punch and die. frictional characteristic, etc.. Therefore, the knowledge of the influence of the process variables is needed in the design of sheet metal forming processes. In this study, the simulation tests of deep drawing for friction coefficient between sheet material and tool were carried out to investigate the influence upon sheet formavility. Experimental results were discussed about the defects on the deformation behaviors during the forming process.

정상과 만성염증성 활막배양세포에서 Corticotropin releasing hormone(CRH)이 cyclooxygenaase-1(COX-1)과 cyclooxygenase-2(COX-2) mRNA발현에 미치는 영향

Corticotropin-releasing hormone(CRH) is a major regulator of the hypothalamic-pituitaryadrenal axis(HPA). In inflammatory stress, the cytokines TNF-, IL-6 stimulate the production of CRH, a 41 amino acids neuropeptide, in the hypothalamus. The release of CRH leads to pituitary production of adrenocorticotropic hormone, followed by glucocorticoid secretion by the adrenal cortex. Glucocorticoids suppress namy components of the inflammatory process. Recently, CRH and CRH receptor were reported to be located in the periphery such as Immune system and chronic inflammatory sites as rheumatoid arthritis (RA). Cyclooxygenase consisted of two isoforms, COX-1 and COX-2, converts arachdonate to prostaglandins(PGs) which are important mediators of inflammation. insymoviocyte in RA, it was described that COX-2 mRNA was markedly increased by inflammatory agents, PMA or IL-1 and COX-1 transcripts were not modulated. We examined the modulation of COX by immune CRH in cultured normal and rheumatoid synoviocytes. Our results were shown that COX-1 mRNA expression decreased with the each stimulation of PMA and IL-1 in normal synoviocyte. In RA synoviocyte, PMA and IL-1 were increased mRNA expression of COX-1. In simultaneous treatment with CRH, PMA group was decreased, but IL-1 group was increased mRNA expression of COX-1. COX-2 mRNA expression was slightly increased by the treatment with PMA and highly increased by IL-1. After CRH treatment, PMA and IL-1 addictively increased COX-2 mRNA expression. We think that these results are contributed to the influence of increased cANP by CRH on the promoter of COX-2 in normal and synoviocytes. Because many cytokines, neuropeptides, and signal transduction pathways are involved in chronic inflammation, the exact role of CRH on inflammation is not fully elucidated. To achieve this goal, further experiments are needed.
