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.

Edible insects are considered novel protein sources, and the edible insect breeding industry is growing rapidly. However, fungal pathogens are a major threat to this industry, and appropriate identification of causative agents is important for the development of antifungal agents. In 2019, strains of the fungal pathogen Metarhizium were isolated from infected second and third instar larvae of the economically important edible insect Protaetia brevitarsis, which were collected from separate farms in Gimhae-si, Gyeongsangnam-do, Korea. Based on morphological characteristics and multilocus phylogenetic analysis of the internal transcribed spacer region, and 50-region of gene encoding the 1-α elongation factor, the fungal strains were identified as Metarhizium majus. Here, we report the detailed phylogenetic characteristics and morphological description of this species, which is prevalent in Korea. Identification of the principal disease-causing agent can help develop disease prevention and antifungal strategies for application in edible insect-rearing farms.

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.

급격한 고령화 사회로의 진입과 서구화된 식습관에 의해 협심증, 심근경색증, 고혈압 등에 의한 심장질환자의 수가 5년간 10만명 이상 증가했다. 심장질환은 지난 8년간 꾸준히 국내 사망원인 2위를 기록 중이며, 이로 인해 연간 소모되는 의료비는 6조원에 달한다. 증가한 환자와 함께 다양한 치료법이 제시되고 있는 가운데, 현재 보편화 된 관상동맥 중재시술 중 스텐트 삽입술의 단점인 재협착이나 장기간 이중항혈소판제 복용으로 인한 출혈의 위험 증가 등의 문제점을 보완하기 위해 약물코팅풍선카테터가 개발되어 점차 상용화되고 있는데, 국내에선 2010년 ‘SeQuent Please^Ⓡ (비브라운코리아)’라는 제품이 처음 출시되면서 약물코팅풍선카테터를 사용한 시술이 시작되었고, 이후 2012년 보험급여가 적용되면서 그 사용량이 본격적으로 늘어났다. 약물코팅풍선치료는 국내뿐만 아니라 전 세계적으로 사용이 증가하고 있는데, 특히 일본을 포함한 아시아태평양 지역에서 그 사용량이 급격히 증가하고 있다. 현재까지 국산 제품의 수요가 증가하고 있는 상황이며 향후, 동물시험 및 임상시험에서의 성능이 입증된다면 위험성이 높은 스텐트 삽입술에 비해 효과적인 시술이 될 것이라 예상한다. As a result of the rapid entry into an aging society and westernized eating habits, the number of heart disease patients caused by angina pectoris, myocardial infarction, and high blood pressure has increased by more than 100,000 over five years. Heart disease has consistently ranked second in the cause of death in Korea over the past eight years, and medical expenses consumed annually reach 6 trillion won. While various treatments are being proposed for more patients, drug-coated balloon catheters have been developed and gradually commercialized to solve the disadvantages of stent implantation such as restenosis and increased risk of bleeding due to long-term double antiplatelet medication. In Korea, it began to use a drug-coated balloon catheter with the first release of it called “SeQuent Please^Ⓡ (Bibrown Korea)” in 2010. Its demand increased gradually as insurance benefits were applied in 2012. Drug-coated balloon angioplasty is increasing in use not only in Korea but also around the world, especially in the Asia-Pacific region, including Japan. Until now, the demand for domestic products is increasing, and if the efficiency in vivo and clinical trials is proven in the future, it is expected to be an effective procedure compared to high-risk stent implantation.

심규원(Sim, Kyu-Won),박헌춘(Park, Heon-Choon),남승민(Nam, Seung-Min) 한국산림휴양복지학회 2021 한국산림휴양학회지 Vol.25 No.2

본 연구의 목적은 경관형용사 분석법을 활용하여 국립공원 내에 있는 마을의 유형별로 경관 선호도에 영향을 주는 경관 이미지를 규명하고자 하였다. 분석 결과, 경관 선호도에 영향을 주는 경관 요인은 마을 유형별로 차이가 있으며, 마을 경관 디자인 가이드라인 수립 시 고려해야할 경관 이미지는 아래와 같다. 첫째, 농촌형 마을의 전원성에만 국한된 형용사는 ‘자연스러운’, ‘풍요로운’, ‘전통적인’, ‘정적인’으로 산촌형 및 어촌형 마을보다는 가장 일반적이고 전통적인 이미지의 고정관념을 지니고 있다고 볼 수 있다. 둘째, 어촌형 마을의 전원성 중 가장 큰 차이를 보이는 부분은 어촌형 마을에만 도출된 형용사 ‘자유로운’이다. 셋째, 산촌형 마을의 형용사적 차이를 보이는 항목은 일반적으로 산의 특성을 반영하는 ‘울창한’, ‘깊은’ 두 단어이다. 도출된 결과를 바탕으로 국립공원 내 존치되어 있는 마을의 정주여건 개선과 공원자원으로서 활용성 제고하고, 공원 내 주민의 삶의 질 향상과 공원 내 마을 이미지를 개선하는데 활용할 수 있을 것이다. The purpose of this study was to identify landscape images that affect landscape preferences by type of village in the national park by using the landscape adjective analysis. As a result of the analysis, the landscape factors that affect landscape preferences vary by village type, and the landscape image to consider when establishing the village landscape design guidelines is as follows. First, adjectives limited to the rural village’s rural originality are ‘natural’, ‘rich’, ‘traditional’ and ‘static’, which have the most common and traditional image stereotypes rather than mountain and seaside villages. Second, the biggest difference among the rural characteristics of seaside villages is the adjective‘free’derived only from this village. Third, the two words that generally reflect the characteristics of the mountain village are ‘dense’ and ‘deep’. Based on the results, it will be able to improve the residential conditions of villages in the national park and improve their utilization as park resources, the quality of life in the park, and the village image in the park.

Purpose: To evaluate the antiadhesive effects and safety of an oxidized regenerated cellulose (Interceed) after thyroidectomy. Methods: Seventy-six thyroidectomized patients were prospectively randomized into two groups with regard to the use of Interceed. We evaluated each group for their adhesive symptoms using four subjective and four objective items at the 2nd week, 3rd and 6th month after thyroidectomy. All patients were examined for vocal cord motility by indirect laryngoscope at each period. Results: Total adhesion scores at each postoperative follow-up period decreased with time, but were not significantly different in each group. The median score for swallowing discomfort for liquid was significantly lower in the Interceed group than in the control group 2 weeks after surgery. In addition, the severity of skin adhesion to the trachea was reduced in the Interceed group compared with the control group 6 months after surgery. During the study, there were no adverse effects or significant differences in postoperative complications between the groups. Conclusion: Interceed appeared to be safe and effective in improving neck discomfort at early postoperative periods and preventing skin adhesion to the trachea 6 months after thyroidectomy.
