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.

This study is aiming at improving the Environmental Conservation Value Assessment Map(ECVAM) of National Land in Korea. The ECVAM items are composed of legal and environmental/ecological assessments. A popular method applied to ECVAM is an overlay environmental/ecological assessment items. The purpose of this study is to offer complementary items of the ECVAM by examining assessment items. In this study we assessed the ECVAM by five methods. Method 1 is Grade 1 areas of each administrative district; Method 2 is comparing overlapped areas of each assessment items Grade 1, 2 and permission of each assessment items duplication; Method 3 is Grade 1, 2 areas by only singular assessment items; Method 4 is Grade 1 areas only of Method 2; and Method 5 is Grade 2 areas only of Method 2. Method 1 showed Seoul and other metropolitan cities revealed a large proportion of Grade I regions by the legal assessment items. Gang won-Do, showed a large proportion of Grade I regions by the environmental/ecological assessment item. Method 2 showed 93.4% of diameter Grade II(standard for stability); forest diameter item accounted for 99.9% by Method 3, Method 4 showed 95.7% of forest diameter, and forest density accounted for 66.4% by Method 5. This study contributes to reduce the complexity in the process of manufacturing ECVAM of National Land, and to raise the flexibility in the process of managing and updating this map.

Objectives: This study was conducted to investigate economic feasibility of operating Regional Cardiocerebrovascular Centers using cost-benefit analysis. Methods: The current study assessed cost and benefit data collected from nine hospitals which were designated as Regional Cardiocerebrovascular Centers between 2008 and 2010. Results: The operation of Regional Cardiocerebrovascular Centers reduced mortality rate and length of stay due to acute myocardial infarction and stroke and also decreased disability occurred after stroke. The total calculated cost of operating nine Regional Cardiocerebrovascular Centers was 19.85-22.30 billion won and the minimum benefit calculated was 23.98 billion won. Applying the maximum cost and the minimum benefit, the net benefit was 1.68 billion won, which is estimated to 190 million won per Regional Cardiocerebrovascular Center. Conclusions: The present study revealed that the operation of Regional Cardiocerebrovascular Centers was economically beneficial. The benefit would be larger if intangible benefit such as the long-term effects to community hospitals and enhancement of quality of life of patients and their families are considered.

A total of 1006 households residing in Seoul, Taegu and Cheonan were surveyed to investigate the consumption pattern and purchasing tendency of processed meat products under the current marketing system. The results are as follows: 1. The average frequency of purchasing meat products was 3-4 times a month and the frequency was closely related to the monthly income of the consumers. A mere 6 percent of respondents with relatively high income purchased more than 10 times per month; whereas, sixty percent of respondents less than 3 times, indicating the consumption of processed meats is at very low level. 2. Sausage(fish-red meat mixture) was purchased most frequently(75%) by all consumption of ham was relatively high (∼20%) at the monthly income level of more than 400,000 won. 3. Meat products were chiefly consumed by children(71%) and teenagers(19%), and were used as side dish in lunch box(41%) or main meal(30%). 4. The average consumers purchased meat products primarily from supermarkets (53.1%), grocery stores(22.5%) and meat shops(16.5%). 5. The procurement of processed meat was determined either by the sole decision of housewife(56%) or by the recommendation of family members(27%). Good nutrition(40.7%) and convenience(29.1%) were the predominant reasons of baying processed meats. The low income people set the highest priority in good nutrition, whereas the high income people in convenience. 6. Forty one percent of respondents have the experience of having purchased foreign products, 15% of them having asserted the superiority of domestic products, while 43% expressed the reverse opinion.

Vasculitis is a heterogeneous group of diseases that destroy blood vessel walls by inflammation. Approximately half of vasculitis cases are idiopathic, but sometimes associated with genetic factors, medicines, chronic infection, autoimmune diseases, and malignancies. Although the mechanism remains unclear, vasculitis secondary to malignancy, also known as paraneoplastic vasculitis, has been reported. It is generally associated with hematologic malignancies rather than solid malignancies and commonly presents as leukocytoclastic vasculitis or polyarteritis nodosa. We experienced a case of leukocytoclastic vasculitis in a patient with hepatocellular carcinoma and membranous obstruction of the inferior vena cava. Here, we report this case with a brief review of literature. (J Rheum Dis 2015;22:322-326)

CO₂ capture from humid flue gases and humid atmosphere using a microporous coppersilicate

Datta, Shuvo Jit,Khumnoon, Chutharat,Lee, Zhen Hao,Moon, Won Kyung,Docao, Son,Nguyen, Thanh Huu,Hwang, In Chul,Moon, Dohyun,Oleynikov, Peter,Terasaki, Osamu,Yoon, Kyung Byung American Association for the Advancement of Scienc 2015 Science Vol.350 No.6258

<P><B>Grabbing CO<SUB>2</SUB> from wet gas streams</B></P><P>It is a challenge to extract CO<SUB>2</SUB> from typical gas streams, such as the flue gas from a power plant. This is because any water in the stream tends to prevent CO<SUB>2</SUB> absorption and may also degrade the absorbing material. Datte <I>et al.</I> developed a microporous copper silicate that avoids these problems. Most other materials have sites that absorb both water and CO<SUB>2</SUB> at the same sites, and in that fight, the water tends to win. Although their material still absorbs water, it has separate sites for the CO<SUB>2</SUB> absorption. It also shows good stability despite the absorbed water and can be reused.</P><P><I>Science</I>, this issue p. 302</P><P>Capturing CO<SUB>2</SUB> from humid flue gases and atmosphere with porous materials remains costly because prior dehydration of the gases is required. A large number of microporous materials with physical adsorption capacity have been developed as CO<SUB>2</SUB>-capturing materials. However, most of them suffer from CO<SUB>2</SUB> sorption capacity reduction or structure decomposition that is caused by co-adsorbed H<SUB>2</SUB>O when exposed to humid flue gases and atmosphere. We report a highly stable microporous coppersilicate. It has H<SUB>2</SUB>O-specific and CO<SUB>2</SUB>-specific adsorption sites but does not have H<SUB>2</SUB>O/CO<SUB>2</SUB>-sharing sites. Therefore, it readily adsorbs both H<SUB>2</SUB>O and CO<SUB>2</SUB> from the humid flue gases and atmosphere, but the adsorbing H<SUB>2</SUB>O does not interfere with the adsorption of CO<SUB>2</SUB>. It is also highly stable after adsorption of H<SUB>2</SUB>O and CO<SUB>2</SUB> because it was synthesized hydrothermally.</P>

1. Objective: Gastric Stuffiness (心下?證) in the Soeumin Taeeum symptomatology (少陰人 太陰病) in Sasang Constitutional Medicine shows an interesting evolutionary process. Originally found in the texts of Sanghanlun (傷寒論), the perspectives regarding the symptoms of Gastric Stuffiness were expanded by many medical scholars and Lee Jema. To comprehend the Jema's concept of Taeeum symptomatology and utilize his prescription clinically, it deserves to study on the Gastric Stuffiness in Donguisuseowon (東醫壽世保元). 2. Methods: Many texts including Sanghanlun (傷寒論) and Dongeuibogam (東醫寶鑑) were reviewed in order to track the evolutionary process concerning the symptoms of Gastric Stuffiness. Also, Lee Jema's works including the different versions of Donguisuseowon (東醫壽世保元) were reviewed to examine the development of Lee's concepts regarding the Gastric Stuffiness in the Soeumin Taeeum symptomatology. 3. Results and Conclusions: 1) Most of the previous concepts on Gastric Stuffiness were generally similar to those found in Sanghanlun, especially in that they addressed Yang deficiency of the middle triple energizeer as the central pathogenic process. 2) Lee Jema's views on the epigastric discomfort in the Soeumin Taeeum symptomatology evoloved over time and culminated in the finalized pathology and therapeutics appearing in his last work, the Shinchuk version of Donguisuseowon (東醫壽世保元). 3) 4 kinds of prescription which invented by Lee Jema to treat the Gastric Stuffiness in the Soeumin Taeeum symptomatology can be matched to the prescription of Sanghanlun respectively. However through evolutionary process of Jema's prescriptions, the indication of them expanded: not only to treat Gastric Stuffiness but to diverse symptoms of Soeumin.
