        Wood products have many attributes that make them a smart choice when it comes to climate change. First, much of the carbon absorbed by growing trees is stored in products. Using more wood also means less fossil fuel consumption. Wood is endlessly renewable, and life cycle assessment studies show that it requires substantially less energy to manufacture than other materials such as steel and concrete. Wood buildings can be easily deconstructed and reused, which means they can continue to store carbon indefinitely. And using wood from sustainably managed forests helps to ensure that forests and their carbon storage potential continue to grow, which contribute to local community economy. This report focuses on international forest policies related to climate change and their implications to Korean forestry and the forest products sector, and some policy suggestions are made. Climate change and climate change mitigation are currently hot topics at the international level. Forest is carbon sink but also regarded as carbon emitter when it is deforested and degraded. REDD(Reducing Emissions from Deforestation and Forest Degradation) and HWP(Harvested Wood Products) are important issues at the post-Kyoto Protocol. Illegal logging is also a major issue in the wood products trade. Major developed countries adopt wood promotion policies to tackle climate change and construct a low-carbon green economy. They promote the merits and provide some technical information when using wood. In Korea, wood consumption is about 27 million cubic meters per year, and self-sufficiency of wood is 13.5%. Domestic wood is used to produce pulp and particle boards in large part. Poor forest resource structure, high cost in wood harvest, negative perceptions to harvest, and low infrastructures are challenging issues in domestic wood supply. The Korean government also adopts Low Carbon Green Growth as a policy base. The demand for wood biomass energy is increasing. These are opportunities to the wood industry. But high production cost in wood harvest and the thin wood consumption culture are weaknesses. We should establish a wood promotion strategy to overcome weaknesses and exploit opportunities. We made some policy suggestions to promote wood use as follows: 1) campaign to increase the utilization and consumption of wood in the public side 2) develop and disseminate durable wood goods, such as engineered wood 3) adopt carbon labelling to show the carbon sequestration function of wood products 4) increase wood supply through utilization of forest residues, short-rotation coppice in idle farmland, and international cooperaton 5) establish technical standards to certify the safety of wood products 6) legislate wood utilization to tackle climate change.

        韓國과 中國의 林産物 交易構造와 特徵

        張哲洙 한국산림경제학회 2003 산림경제연구 Vol.11 No.1

        중국은 WTO가입에 따라 시장개방과 함께 외국인 직접투자가 이루어질 수 있도록 사업 환경을 개선시켜 나아갈 것이다. 이것은 중국이 세계경제로 통합되어 간다는 것을 의미하며, 또한 우리나라를 포함한 세계 여러 국가들에게 있어서 기회와 도전을 의미하고 있다. 즉 중국으로부터 기타 여러 국가들에 대해 수출물량이 증가하게 되면 교역 상대국의 수입가격은 내려가게 될 것이고 경쟁력을 향상시키게 될 것이다. 다른 한편으로는 유사한 상품들을 생산하는 국가들은 제3 시장에서 중국산과의 경쟁이 심화될 것이다. 이 연구에서는 한국과 중국간의 임산물 교역구조와 특징을 분석하였다. With WTO accession, China will continue the process of opening its markets to other countries' exports and improving its business climate for foreign direct investment. This means China's deeper integration into the world economy and present both opportunities and challenges for other countries including Korea. Increased exports from China to other countries will lower the import prices of its trading partners and improve their competitiveness. On the other hand, countries that produce similar products will face increased competition with China in third markets. This study deals with structures and characteristics of forest product trades between China and Korea.

      • 木材資源經營에 있어서 目標計劃法의 適用性에 關한 硏究 : 本校 永同 演習林을 中心으로 in training forest (Young-Dong) of Kyung-Hee Univ.

        張哲洙,李鍾樂 慶熙大學校 1994 論文集 Vol.23 No.-

        This study presents a cast study which deals with the application of GP(Goal Programming) to timber resource management problem in the Kyung Hee University training forests(Young-Dong). The management criteria used for the analysis were timber volume maximization, normal age-class distribution, and periodic sustained yield. Six arrangements of goal rankings and three alternatives in goal achievement constraint type for sensitivity analysis were used and discussed. Also, the general framework for the GP formulation of a timber harvest scheduling problem and the timber harvest area and volume production plan were suggested. The analysis of GP output provides valuable information with respect to resource allocation problems having several conflicting objectives for the decision maker. It therfore assists in dertermining how resources should be allocated to meet specified goal and in analysis consequent the impacts and trade-offs occuring if certains are made.

        韓國과 中國의 林産物 國際競爭力

        張哲洙,張宇煥,鄭靖吉 한국산림경제학회 2002 산림경제연구 Vol.10 No.2

        WTO 출범으로 세계 경제가 무역자유화를 통한 하나의 시장으로 빠르게 통합되고 있다. 특히 중국의 WTO가입은 세계무역뿐만 아니라 우리나라 임산업에도 크게 영향을 미칠 것으로 예상된다. 이러한 세계적 조류속에서 우리나라 임산업이 발전하기 위해선 경쟁력을 높여 나가는 것 외에는 대안이 없다. 여기에서는 우리나라 주요 수출임산물을 대상으로 한ㆍ중 임산물이 세계시장에서 갖는 국제 경쟁력, 상대국 또는 제3국에 대한 수출의존도, 상대국 또는 제3국 시장에서 보여주고 있는 상대적인 경쟁력, 그리고 각 국의 수입의존도 등을 비교 검토해 봄으로서 향후 우리나라 임산물의 대중국뿐만 아니라 제3국 시장으로의 수출확대를 위한 대응방안 마련에 기초자료를 제시하고자 하였다. With the launch of WTO, we can no longer think of our domestic interests and policies without reference to the wider global context. In particular, since China occuies important position in the world agriculture, forest industry, and trade, it is expected that China's joining to the WTO will substantially influence the world trade and forest industry in Korea. One alternative is to strengthen the international competition of our forest products for the development of our forest industry. In this context, the purposes of this paper are laid at the analysis on the international comparatives of some forest products in Korea and China, on the basis of Revealed Comparative Advantage Index(RCA), Exporting Dependent on a particular Country, Comparative Advantage by Countries (CAC), Market Share(MS), etc. This paper also suggests ways to strengthen the international competition of our forest producs in the market of China and Japan.

        감귤류 종자 추출물의 N-nitrosodimethylamine 생성억제에 관한 연구

        오혁수,안용석,나임순,오명철,오창경,김수현 한국조리과학회 2003 한국식품조리과학회지 Vol.19 No.5

        The effect of inhibition on N-nitrosodimethylamine (NDMA) formation by methanol extracts from 6 kinds of citrus seed (Citrus sunki, Citrus natsudaidai, Citrus suleata, Citrus tangerina, Citrus grandis and Citrus obovoidea) were investigated. The contents of moisture, crude protein, crude fat, carbohydrate, ash, flavonoid and totat phenol in citrus seeds were 4~6, l1~15, 32~46, 22~45, 2~4%, 12~24mg% and 53~133㎎%, respectively. The solid contents and yield of citrus seed extracts were 0.8~1.0 and 0.7~1.1%, respectively. Nitrite-scavenging activity by methanol extracts from citrus seeds increased with increasing extract dosage. Furthermore, the nitrite scavenging activity was pH dependent being the highest at pH 1.2 (42.7~96.9%) and the lowest at pH 6.0 (19.9~62.6%). Scavenging effects of nitrite by reaction time showed high effects under 3hr reaction time. The inhibition effect of NDMA formation by the citrus seed was strengthened as the amount of extract increased. The inhibition rate of methanol extracts from citrus seeds on NDMA formation showed 1.2~39.8%, 21.3~60.1% and 47.4~94.0%, according to add 1, 3 and 5㎖, respectively. Therefore, the inhibition effect of NDMA formation by the citrus seed was strengthened as the concentration of extract increased.

        Purpose: We sought to determine the efficacy of extracorporeal shock wave lithotripsy(ESWL) in the treatment of urolithiasis with congenital upper urinary tract anomalies. Materials and Methods: Using the Northgate SD-3 lithotriptor, 43 patients with calculi with upper urinary tract anomalies were treated with extracorporeal shock wave lithotripsy(ESWL) at Chosun University Hospital from 1996 to 1998. The upper urinary tract anomalies were duplicated ureter in 12 cases, bifid pelvis in 10, malrotated kidney in 4, ureterocele in 3, UPJ obstruction in 3, caliceal diverticulum in 3, horseshoe kidney in 3, pelvic kidney in 2, medullary sponge kidney(MSK) in 2 and polycystic kidney in 1. The age range of the patients was from 22 to 70 years of age(mean of 49.6 years). There were 23 men and 20 women. The mean size of the stone was 10.1x8.6±4.9x4.3mm, General or regional anesthesia was not required. Results: The average frequency was 2.3 sessions and the average number of shock wave was 2258±1404 shock. The 3-month stone free rate was 90.7%, Complications of stone removal were petechia in 43 cases, gross hematuria in 36, severe flank pain in 9 and urinary infection in 2. All complications were treated successfully with conservative management. Conclusion: We conclude that ESWL monotherapy is a safe and successful modality as a noninvasive management of urolithiasis in patients with upper urinary tract anomalies.
