흑마늘로 잼을 만들어 품질특성을 알아본 결과, pH 및 산도는 MTS 첨가군이 pH가 가장 높았으며 산도는 대조군이 가장 높았다. 환원당 함량은 MT 첨가군, MTS 첨가군 순으로 환원당 함량이 높았다. 점도는 MT 첨가군, MTS 첨가군 순이었고, 대조군은 가장 낮았다. 색도는 명도는 MT군이 가장 높았으며 적색도는 대조군이 말티톨시럽을 첨가한군에 비하여 높았다. 황색도는 MTS군이 가장 높았다. 기계적인 조직감 측정결과, 경도와 부착성은 MT 첨가군이 가장 높고 그다음이 MTS, 대조군의 순이었다. 탄력성과 응집성은 처리간에 유의적인 차이가 없었다. DPPH radical 및 hydroxy radical 소거능 측정에 의한 항산화능은 MT군이(DPPH $IC_{50}$: 49.63 mg/g, hydroxy radical $IC_{50}$: 27.24 mg/g) 가장 높았고 그다음이 MTS군이었으며 대조군은 가장 낮았다. 총페놀함량은 MT군이 가장 높고, 그다음이 MTS군, 대조군의 순으로 항산화능 결과와 일치하였다. 관능검사결과, 마늘냄새는 MT군과 MTS군이 낮았으며, 기호도 검사에서 향미와 전반적인 수용도는 MTS군이 6.9점 및 6.6점으로 가장 높은 점수를 받았으며, 설탕군은 5.8점으로 말티톨군의 5.3점과 유사하였다. 제품구입의사는 MTS군이 6.8점으로 가장 높은 점수를 받았으며, MT군은 낮은 점수를 받았다. 이와 같은 결과를 종합해보면 잼 제조시 설탕을 말티톨로 대체시 50% 정도만 대체하는 것이 관능적으로 가장 좋다고 사료된다. The antioxidant activities and quality characteristics of jams containing maltitol substituted for sucrose(sucrose, maltitol syrup(MT), and MTS(sucrose 50%+MT 50%)) were evaluated. The endpoint of jam preparation was determined to be 64 $^{\circ}Brix$. The pH was the highest in MTS among all treatments. The reducing sugar content and viscosity were the highest in MT, and second highest in MTS. Lightness(L value) of Hunter color system was the highest in MT, whereas yellowness(b value) was the highest in MTS. Hardness and cohesiveness of textural properties were the highest in MT. Antioxidant activities were the highest in MT, which also had the lowest $IC_{50}$ values(49.63 mg/g for DPPH and 27.24 mg/g for hydroxyl radical scavenging activity). Total phenol content was highest in MT among all treatments. Flavor and overall acceptance scores of MTS were the highest among all treatments. Based on these results, it was suggested that half-substitution of sucrose with maltitol is the most appropriate for attaining favorable physicochemical and antioxidative properties during black garlic jam preparation.

P3HT:PCBM 층 내 분산 가능한 금속 나노입자의 제조 및 이를 포함한 고분자 태양전지 소자의 특성에 관한 연구

김민지,최규채,김영국,김양도,백연경,Kim, Min-Ji,Choi, Gyu-Chae,Kim, Young-Kuk,Kim, Yang-Do,Baek, Youn-Kyoung 한국분말야금학회 2014 한국분말재료학회지 (KPMI) Vol.21 No.3

In this study, we prepare polymer solar cells incorporating organic ligand-modified Ag nanoparticles (O-AgNPs) highly dispersed in the P3HT:PCBM layer. Ag nanoparticles decorated with water-dispersible ligands (WAgNPs) were also utilized as a control sample. The existence of the ligands on the Ag surface was confirmed by FT-IR spectra. Metal nanoparticles with different surface chemistries exhibited different dispersion tendencies. O-AgNPs were highly dispersed even at high concentrations, whereas W-AgNPs exhibited significant aggregation in the polymer layer. Both dispersion and blending concentration of the Ag nanoparticles in P3HT:PCBM matrix had critical effects on the device performance as well as light absorption. The significant changes in short-circuit current density ($J_{SC}$) of the solar cells seemed to be related to the change in the polymer morphology according to the concentration of AgNPs introduced. These findings suggested the importance of uniform dispersion of plasmonic metal nanoparticles and their blending concentration conditions in order to boost the solar cell performance.

Carbon nanotube fibers (CNTFs) have attracted wide attention owing to their exceptional lightness, electrical conductivity, and mechanical flexibility that make them potential components for applications including carbon composites, nanoelectronics, and optics. CNTFs have been successfully fabricated from carbon nanotubes (CNTs) by liquid-crystal spinning. This spinning method requires low-defect CNTs to form a liquid crystalline phase for making highly-oriented CNTFs. In this study, we conducted microwave purification to effectively remove impurities from CNTs, such as residual metallic catalyst and carbon-based impurities, that are formed during CNT synthesis. We fabricated single-walled carbon nanotube fibers (SWCNTFs) using liquid-crystal spinning purified single-walled carbon nanotubes (SWCNTs) to examine the effect of SWCNTs on the liquid crystal phase and resultant fibers. In conclusion, this method removed impurities from SWCNTs and increased the oxygen-containing functional groups in the SWCNTs, which are capable of forming a liquid crystal phase, thereby enhancing the mechanical performance of fibers.

Due to the lack of flood data, the water engineering practice calculates the design flood using rainfall frequency analysis and rainfall-runoff model. However, the rainfall frequency analysis for arbitrary duration does not reflect the regional characteristics of the duration and amount of storm event. This study proposed a practical method to calculate the design flood in a watershed considering the characteristics of storm event, based on the bivariate rainfall frequency analysis. After extracting independent storm events for the Pyeongchang River basin and the upper Namhangang River basin, we performed the bivariate rainfall frequency analysis to determine the design storm events of various return periods, and calculated the design floods using the HEC-1 model. We compared the design floods based on the bivariate rainfall frequency analysis (DF_BRFA) with those estimated by the flood frequency analysis (DF_FFA), and those estimated by the HEC-1 with the univariate rainfall frequency analysis (DF_URFA). In the case of the Pyeongchang River basin, except for the 100-year flood, the average error of the DF_BRFA was 11.6%, which was the closest to the DF_FFA. In the case of the Namhangang River basin, the average error of the DF_BRFA was about 10%, which was the most similar to the DF_FFA. As the return period increased, the DF_URFA was calculated to be much larger than the DF_FFA, whereas the BRFA produced smaller average error in the design flood than the URFA. When the proposed method is used to calculate design flood in an ungauged watershed, it is expected that the estimated design flood might be close to the actual DF_FFA. Thus, the design of the hydrological structures and water resource plans can be carried out economically and reasonably.

이매방 살풀이춤의 ‘여형화(女形化)’에 대한 논의

김기화 ( Kim Ki-hwa ) 한국무용연구학회 2020 한국무용연구 Vol.38 No.1

우리는 이매방의 춤을 이야기할 때 ‘아름답다’, ‘교태적이다’, ‘농염하다’라고 표현한다. 이러한 수사(修辭)는 그의 춤이 다분히 여성적인 속성을 갖고 있기 때문에 붙여진 것이다. 본 연구는 이매방의 살풀이춤이 여형화의 양식체계로 구축되어 있음을 논의하였다. 춤에서 ‘여형화’란 남성이 여성의 모습으로 춤을 추는 형식, 혹은 양식이라고 할수 있다. 이매방의 춤은 다음과 같은 여형화의 특성을 보인다. 첫째, 이매방의 살풀이춤은 경극의 ‘화단’이나 가부키의 ‘게이세이’와 같이 화려하고 교태스런 배역 특성을 보인다. 둘째, 살풀이춤의 복식은 남성과 여성의 구분을 두고 있으되 상당히 장식적인 여성성을 지향하고 있다. 셋째, 이매방의 양성 지향적인 성 정체성은 탐미적인 미의식으로 확장되어 여형화 된 춤 양식 체계로 환원되었다. 넷째, 이매방 살풀이춤의 기법은 가공된 여성의 신체상을 기반으로 구축되었다. 즉, 응축된 근육의 밀도 높은 작용을 통해 신체를 ‘축소’하거나 ‘왜곡’하여 관능적이고 요염한 여성성을 신체상으로 구현하여 춤에 반영하였다. 이상으로 미루어 이매방 살풀이춤은 남성이 추는 여성의 춤, 혹은 기방춤을 전형 특성의 하나로 구축하고 있다고 하겠다. When we talk about Lee Mae-bang's Salpul-i chum, we use the expressions ‘beautiful’, ‘exciting’, and ‘congested’. This knowledge was attached because his dance has a feminine attribute. This study discussed that Lee Mae-bang's Salpul-i chum is constructed as Yeohyeonghwa's aquaculture system. First, Lee Mae-bang's Salpul-i chum exhibits gorgeous and cunning character, such as Peking Opera's 'Huā dàn' or Kabuki's 'Keisei'. In dance[chum], ‘Yeohyeonghwa’ can be said to be a form or style in which men dance in the form of women. Lee Mae-bang's dance shows the following characteristics of Yeohyeonghwa. Second, Salpul-i chum's costumes differentiate between men and women, but aim for a highly decorative femininity. Third, Lee Mae-bang's bisexual sexual identity has been stylized into a feminine attitude through aesthetic pursuit. Fourth, Lee Mae-bang Salpul-i chum's technique expresses the processed female body image. In other words, Salpul-i chum expresses the body of a sensual and fascinating woman by 'shrinking' or 'distorting' the body through the dense action of condensed muscles. In this regard, Lee Mae-bang is said to be constructing a male dance or gibangchum as one of the characteristics of Jeonhyeong[original form].

Antidepressants are widely used to treat depression in Korea, however, only a few studies have focused on the provider of the treatment. The aim of the study is to compare the differences between patients who were prescribed antidepressants by psychiatrists and those who were prescribed antidepressants by non-psychiatrists in South Korea. Patients with a diagnosis of depressive disorder who had been newly prescribed antidepressants in 2012 were selected from the Health Insurance Review and Assessment Service database. They were classified into two groups depending on whether they received the antidepressant prescription from a psychiatrist or non-psychiatrist. Sociodemographic, clinical, and depression related cost has been investigated. Treatment resistant depression, which is defined as a failure of two antidepressant regimens to alleviate symptoms, was also investigated. Prescription adequacy was assessed based on whether a regimen was maintained for at least 4 weeks. Among the 834694 patients with pharmaceutically treated depression (PTD) examined in this study, 326122 (39.1%) were treated by psychiatrists. Patients who were treated by psychiatrists were younger and had more psychiatric comorbidities than those treated by non-psychiatrists. They had longer PTD duration (229.3 days vs. 103.0 days, p < 0.05) and a larger proportion of treatment resistant depression (9.3% of PTD) when compared to those patients treated by non-psychiatrists. The patients treated by psychiatrists had a smaller proportion of inadequate antidepressant use compared to those patients in the non-psychiatrist group (44.5% vs. 65.1%, p < 0.05). The costs related to depression corrected with PTD duration were higher in the non-psychiatrist group (32214 won vs. 56001 won, p < 0.05). Patients who receive antidepressants from psychiatrists are patients with more severe, treatment-resistant depression. Psychiatrists prescribe antidepressants more adequately and cost- effectively than non-psychiatrists.

Metal (loid)s such as environmental contaminants affect food safety. Metal (loid)s exist trace extremely in agriculture products. Therefore it is important to analyze accurately about trace these metals. High resolution techniques and quality controls are needed to analyze these materials. In order to achieve quality results, standardized methods and techniques are required. So ISO(International Organization for Standardization) of laboratory proficiency testing is determination of laboratory testing performance by means of inter-laboratory comparison. The values have been derived as a consensus of a number of laboratories using a variety of methods. Proficiency tests were applied to analyze the metal(loid)s [inorganic arsenic (As), total As and cadmium (Cd)] in powdered rice FAPAS 07187 (Food Analysis Performance Assessment Scheme; February-April 2013). The rice powder sample was extracted with 1% HNO3 for inorganic As for microwave-assisted extraction using water at 95℃ for 90 min and their analysis by HPLC/ICPMS. Also, HNO3 for total As and Cd using microwave-assisted extraction using at 200℃ for 50 mins and analysis by ICP/MS. Validation check was performed for accuracy using CRM (NMIJ CRM 7503-a) for inorganic As, and CRM (IRMM-Rice CRM) for total arsenic and cadmium. The result were satisfactory. FAPAS 07187 the z-scores of inorganic As, total As and Cd in powdered rice were-1.8,-0.9 and 0.2(lzl<2, respectively).

Objectives : This study investigated warning signs and stroke presymptoms and their relationship with acute stroke patients in each stroke type. Methods : 217 patients with first-ever acute stroke within 2 weeks as the case group, 146 people without four major risk factors (hypertension, diabetes mellitus, hyperlipidemia and ischemic heart disease) as the healthy control group (Normals), and 160 people as the general control group (Controls) were recruited at the Stroke Medical Center in Daejeon University Oriental Medicine Hospital from July 2005 to March 2007 for this case-control study. We analyzed the odds ratio of each warning sign or presymptom by multivariate logistic analysis and evaluated each stroke type, as well as general characteristics such as age, sex, etc. Results : Paralysis or weakness of the face and limbs, visual field disorder or loss of vision or blurred and double vision in eyes or both eyes, and sudden difficulty in speaking or dysarthria showed significant increase respectively in each stroke type. In contrast, numbness or tingling sensation or lowering sensation of the face and limbs, numbness or dead sensation of 1st and 2nd fingers, tension at cervical lesion, blepharospasm, facial spasm, etc. had no significant relation with stroke occurrence. Conclusions : In this study we demonstrated that each presymptom have an influence on each stroke type and have different odds ratio for stroke. We believe this may contribute to interpreting the importance of warning signs or presymptoms for each type of stroke, and more prospective studies are needed.
