최근 중국은 양산항을 개장하여 선사 유치를 위한 다양한 혜택을 제공하고, 일본은 "수퍼중추항만 육성계획“을 세워 항만의 효율성을 바탕으로 비용을 낮추려는 노력을 하고 있다. 또한 선박의 대형화에 의한 중심항만(Hub Port) 위주의 기항과 북중국의 대량 물량 발생지역에 대한 직기항 경향으로 동북아 항만간의 경쟁이 더욱더 치열해 지고 있으며 동북아 역내 피더네트워크 강화의 필요성이 제기되고 있다. 따라서, 본 연구에서는 유럽 피더네트워크 전략 사례를 바탕으로 동북아 피더시장 현황을 파악하고 동북아 피더네트워크 구조를 분석함으로써 동북아 역내 항만 및 선사간의 과당경쟁을 지양하고 서로 Win-Win할 수 있는 터미널의 전략적 활용, 선사간 제휴 확대, 항만간 협력 강화를 위한 구체적인 전략을 제시하였다. Recently, China opened Yangshan port and provides a variety of benefits for shipping companies. Japan plans to reduce logistics costs and improve efficiency through the established "super major ports" project. According to the "hub and spokes" system, the number of direct calls toward North-Chinese ports are increasing. This changing environment has negative effects on the amount of transshipment cargos in Korean ports. In order to make a hub port of a domestic port, it is necessary to develop northeast Asian feeder networks. Therefore, this paper analyzes the structure of northeast Asian feeder networks through the case study of European feeder networks strategy. Finally, we suggests the plans to reinforce feeder networks, which are strategic terminal operation, strategic alliances between shipping companies and port co-operation, for win-win strategy in the competitive northeast Asian market.

The purpose of this survey is to investigate and analize the status of flower consumption by city households so that it can provide basic materials for the development of horticulture industry. For this purpose, one thousand housewives were questioned living in six large cities : Seoul, Pusan, Taegu, Inchon, Kwangju and Taejon. The results of the analysis are as follows; 1. The most favorite cut flowers by season were rose, carnation and freesias in spring: roses and gypsophila paniculate in summer : chrysanthermum in autumn : gypsophila paniculate, roses chrysanthemums and lilies in winter. 2. The uses of cut flowers was mostly for gifts(58.4%), and that of pot flowers was mostly for home decoration. 3. flower shops were the most popular place for buying cut flowers(59.5%), followed by wholesale markets(22.5%) and street stalls(16.2%). In the case of pot flower, wholesale markets were the most favorite place(32.4%), street stalls(27.9%), flower shops(24.8%), and farm houses(11.9%). The survey showed that consumers frequent a shopping place because of 'easy accessibility', and 'various varieties in stock' in the case of cut flowers and, in that of pot flowers, 'easy accessibility' and 'low price' were the main resons in the case of pot flowers. 4. The purchase frequency rate by seson for cut flowers was that 'regardless of season' was 58.1% and 'spring', 28.9%. For pot flowers, 'spring' 58.9% and 'regardless of season' 33.6%. For the day of the week cut flowers were bought most open, Saturday came first with 34.2%, Monday and Sunday followed with 27.0% and 15.5% respectively. On the other hand, Sunday came first with 42.3%, Saturday(32.5%) and Monday(8.3%) took the second and third place respectively for pot flowers When it came to the purchase time of the day for cut flowers, 31.8% of the respondents bought then between ten and noon and 21.8% between four and six in the afternoon. 5. concerning the average amount of money spent at one time for cut flowers, 33.3% of the respondents said 3,000won to 5,000won and 23.2% replied 5,000won to 10,000won. While 36.8% answered that they paid 5,000won to 10,000won and 23.5% said 3,000won to 5,000won for a pot flowers. 6. Relating to the demand of flower stores, 28.8% wanted 'low price' : 27.9%. requested 'clear markings of the prices' : and 26.4%, wanted 'abundant commodities'

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.

In this study, we tested the influences of several κ opioid ligands on the [³H]diprenorphine binding in rat and guinea pig cortex membrane preparations. Using paradigm to block μ and δ opioid receptors with DAMGO(1μM) and DPDPE(1μM), [³H]diprenorphine labeled κ sites. Competition analysis in both rat and guinea pig cortex has shown a single population of [³H]diprenorphine binding site with different Kd values, respectively. There is a significant difference in Ki values of (-) WIN44441 and (+)WIN44441 in both rat and guinea pig cortex. Bremazocine, (-)ethylketocyclazocine, (-)cyclazocine, nor-binaltorphimine effectively inhibited the [³H]diprenorphine binding with different Ki values in rat and guinea pig cortex. U-69,593, U-50,488H and dynorphine-A (1-8) did not inhibit the [³H]diprenorphine binding in rat but in guinea pig cortex. Nor-binaltorphimine was a ligand discriminate the κ₁, and κ₂ receptor most effectively. We, also, examined the influence of Na ion and GTPγS, a nonhydrolyzable guanine nucleotide analog, on the inhibition of [³H]diprenorphine binding by diprenorphine, (-)ethyl-ketocyclazocine, U-69,593 and bremazocine. By the replacement of NaCl with N-methy-D-glucamine or addition of GTPγS, Ki values of diprenorpnine were not changed and that of ethylketocyclazocine were changed significantly in both rat and guinea pig cortex. The Ki value of bremazocine was decreased by removal of Na ion, and increased by GTPγS, however, was not changed by any one of either. These results suggest that there are 2 kinds of subtypes of κ opioid receptor, κ₁, and κ₂, showing different Ki values for various κ opioid ligands, also, bremazocine possess the antagonistic property at κ₂ site which is dominant subtype of K receptor in rat cortex.

Objectives : To estimate the economic burden of osteoporotic vertebral fracture (VF) from a societal perspective. Methods : From 2002 to 2004, we identified all National Health Insurance claims records for women ${\geq}50$ years old with a diagnosis of VF. The first 6-months was defined as a "clearance period," such that patients were considered as incident cases if their first claim of fracture was recorded after June 30, 2002. We only included patients with ${\geq}$ one claim of a diagnosis of, or prescription for, osteoporosis over 3 years. For each patient, we cumulated the claims amount for the first visit and for the follow-up treatments for 1 year. The hospital charge data from 4 hospitals were investigated to measure the proportion of the non-covered services. Face-to-face interviews were conducted with 106 patients from the 4 study sites to measure the out-of-pocket spending outside of hospitals. Results : During 2.5 years, 131,453 VF patients were identified. The patients had an average of 3.38 visits, 0.40 admissions and 6.36 inpatient days. The per capita cost was 1,909,690 Won: 71.5% for direct medical costs, 20.6% for direct non-medical costs and 7.9% for indirect costs. The per capita cost increased with increasing age: 1,848,078 Won for those aged 50-64, 2,084,846 Won for 65-74, 2,129,530 Won for 75-84and 2,121,492 Won for those above 84. Conclusions : Exploring the economic burden of osteoporotic VF is expected to motivate to adopt effective treatment options for osteoporosis in order to prevent the incidence of fracture and the consequent costs.

소수력발전은 하수처리장 에너지 자립을 위한 효과적인 대안이다. 본 연구는 유량변동이 크고 유효낙차가 낮은 중소형하수처리장(기흥레스피아) 적용을 위해 피치조절형 세미카플란(semi-kaplan) 마이크로수력발전의 적용 타당성을 평가하였다. 가변피치 semi-kaplan 수차는 유량조절을 위한 가이드베인은 생략하고 피치조절형 런너를 장착하여 기계적 결함은 줄이면서 유량변동이 큰 처리장에 특화된 기술이다. 마이크로수력발전 시스템은 설계조건(유량 0.35 m3/s, 유효낙차 4.7 m)에서 90.2%의 수차효율 달성이 가능하였고 발전용량은 13.4 kW로 산정되었다. 설비가동률 74%로 가동 시 연간 약 86.8 MWh 에너지 생산을 통해 2.1%의 에너지 자립이 가능하고 이는 연간 49톤의 CO₂ 감축효과와 맞먹는다. 경제성 평가결과 초기 건설공사비가 200,000,000원 이하인 경우에는 내부수익률은 6.1%, 순현가는 15,539,000원, 편익-비용률은 1.08, 투자회수년은 15.5년으로 경제성이 충분한 것으로 나타났다. Small scale hydropower is one of most attractive and cost-effective energy technologies for installation within sewage treatment plants. This study was conducted to evaluate the potential of a semi-kaplan micro-hydropower (MHP) system for application to sewage treatment plants with high flow fluctuations and a low head. The semi-kaplan MHP is equipped with an adjustable runner blade, and is without a guide vane, so as to reduce the incidence of mechanical problems. A MHP rating 13.4 kWp with a semi-kaplan turbine has been considered for Kiheung Respia sewage treatment plant, and this installation is estimated to generate 86.8 MWh of electricity annually, which is enough to supply electricity to over 25 households, and equivalent to an annual reduction of 49 ton CO₂. The semi-kaplan turbine showed a 90.2% energy conversion efficiency at the design flow rate of 0.35 m3/s and net head of 4.7 m, and was adaptable to a wide range of flow fluctuations. Through the MHP operation, approximately 2.1% of total electricity demand of Kiheung Respia sewage treatment plant will be achievable. Based on financial analysis, an exploiting MHP is considered economically acceptable with an internal rate of return of 6.1%, net present value of 15,539,000 Korean Won, benefit- cost ratio of 1.08, and payback year of 15.5, respectively, if initial investment cost is 200,000,000 Korean Won.

To investigate the renal effects of enrofloxacin administration on rats induced with dehydration or hyperoxaluria, male rats were treated with enrofloxacin of 50 mg to 500 mg/kg b.w.. The microscopical observations of kidney and urine sediment were carried out in the experimental groups. The result obtained were as follows; The male rats deprived of water for 72 hours and administered with enrofloxacin. As enrofloxacin administration dose was increased, clinical signs such as loss of appetite, depression, weakness, and loss of urine output became more severe. In the histopathological findings, there were hyperemia and hemorrhage in renal cortex, vacuolation and necrosis of renal tubular epithelia, proteinous casts within renal tubules. The male rats were orally administered with sodium oxalate and injected with enrofloxacin for 7days. As enrofloxacin administration dose was increased, clinical signs such as the loss of appetite and water consumption, and weakness became more severe. In the histopathological findings, there are hemorrhage of glomeruli and cortical hyperemia, vacuolation and necrosis of tubular epithelia, proteinous casts in renal tubules. In the microscopical findings of urine sediment, there are calcium oxalate crystal (diamond-like type) and magnesium ammonium phosphate crystals (rhomboid). The male rats were intraperitoneally injected with sodium oxalate and administered with enrofloxacin for 7days. As enrofloxacin administration dose was increased, clinical signs such as the loss of appetite and water consumption, weakness were more severe. In the histopathological findings, there were hyperemia and hemorrhage in both glomeruli and renal cortex. Severe necrosis of renal tubular epithelia, bluish materials within renal tubules were also found. In the microscopical findings of urine sediment, there were many calcium oxalate crystals. The present results suggest that enrofloxacin has some injurious effects in rats having dehydration or hyperoxaluria, and clinically, we should consider these renal injury effects when we use enrofloxacin in patients accompanied renal disease, dehydration and hyperoxaluria conditions.

As vincristine, one of the vinca alkaloids isolated from VInca rosea Linn ingibits mitosis by binding to tubulin, the basic protein subunit of the microtubles resulting in disruption of the mitotic spindle apparatus, this drug has been used for the treatment of many neoplastic diseases. However, vincristine is also known to cause many side effects such as neurotoxicity, suppression of bone marrow function and hypofunction of the liver cells etc. The present study was performed to explore the effect of vincristine on the fine structure of organelles in the uterine glandular cells of the mice at different stages of the estrous cycle. Vincristine dissolved in normal saline(1.6mg/kg) was given intraperitoneally to the animals of the experimental group and normal saline to those of the control group for 4 days. All the animals was sacrificed on the 5th day, and specimens were obtained from the corpus uteri. Thin section(600-800 A thick) made from each specimen were stained with uranyl acetate and lead citrate and observed with electron microscope(Hitachi-600). In the uterine glandular epithelial cells of vincristine treated mice at the proestus stage, the following changes were observed: a decrease of mocrovilli, partial disorganization of the cristae and disruption of the membrane of mitochondria, fragmentation or sacculation of the cisternae of rough endoplasmic reticulum associate with detachment of the ribosomes, and appearance of numerous autophagic vacuoles, multivesicular bodies as well as primary lysosomes. Similar changes in ultrastructure of the uterine glandular epithelium were identified in the drug-treated animals at the estrus stage. All the changes induced by vincrisitne in the fine structure of organelles of these epithelial cells at the metestrus stage or diestrus stage were not much different from those produced at the estrus stage. The results of present study suggest that due to its cytotoxicity may cause degenerative changes in the uterine glandular epithelial cells of mice in all stages of the estrous cycle.
