The main purpose of this study was to examine the correlation between the consumption of red ginseng-based ‘SSR’ for 30 days and the reduction in human fatigue, blood component changes, and immune cell activity in 35 human subjects. ‘SSR’ is composed of zinc oxide, folic acid, and D-α-tocopherol with red ginseng as the main component. According to the protocol criteria of the study, 35 subjects who understood the purpose of the study and signed an informed consent form were selected. The fatigue survey was conducted through a questionnaire, and after taking ‘SSR', a decreased tendency of physical, mental, and neurosensory fatigue was observed. In hematological analysis, no significant changes were observed in the levels of WBC, RBC, and hemoglobin; however, AST (SGOT) and ALT (SGPT) levels were statistically significantly decreased. In immunological analysis, it was observed that the proliferative effect of T cells (CD3+CD4+) was greater than that of NK cells (CD16+CD56+). The collected data were subjected to t-test analysis using the SPSS 25.0 statistical program. The result from this study proposes that ‘SSR’ can be used as a functional food material as it reduces human fatigue and enhances immune function.

목적: 대학생 소비자의 안경구매행태와 소비가치가 소비만족도에 영향을 미치는지 연구하기 위하여 인구 통계학적 특성에 따라 안경구매행태에 차이가 있는지 확인하고 소비가치가 대학생 소비자의 소비만족도에 영향을 미치는지 확인한다. 방법: 본 연구대상의 표본은 2017년 6월 1일부터 6월 15일까지 익산 소재 대학교의 대학생들을 대상으로 직접 설문방식으로 조사하였고, 총 320부의 설문지를 배포하여 응답이 누락되어 분석에서 제외한 17부를 제외하고 최종 302부를 분석 자료로 이용하였다. 기술통계분석, 빈도분석, 카이스퀘어 검증, 다중회귀분석을 실시하였다. 결과: 조사대상자의 안경구매행태를 살펴보면, 평균안경교체주기는 ‘1년 이상 2년 미만’이 32.1%로 가장 높게 나타났고, 안경교체이유는 ‘도수 변화’가 39.1%로 가장 높게 나타났으며, 안경선택에 영향을 주는 사람 은 ‘나 자신’이 70.2%로 가장 높았다. 안경구매 시 가장 중요한 선택요인은 ‘디자인’이 가장 중요하다고 응답 한 경우가 52.6%로 가장 높게 나타났다. 인구통계학적 특성에 따른 안경구매행태의 차이를 분석한 결과, 여 성보다 남성이, 소득이 많은 사람이, 안경을 착용한지 얼마 되지 않은 대학생들이 더 안경교체를 쉽게 결정 하였다. 남성의 안경교체이유는 ‘안경파손’, ‘렌즈흠집’, ‘유행 뒤처짐’ 순이었으나 여성은 ‘도수 변화’가 51.9%로 압도적으로 높게 나타났다. 안경착용기간이 ‘10년이상’인 집단은 ‘도수 변화’ 비율이 48.8%로 다른 집단에 비해 높았다. 소득수준이 높은 집단이 소득수준이 낮은 집단보다 안경선택이유로 디자인을 최우선 하는 것으로 나타났고 소득수준이 낮은 집단이 높은 집단보다 안경선택이유로 가격을 최우선하는 것으로 나 타났다. 본 연구에서 조사대상자인 대학생들에게 안경구매는 미래보다는 현재에 가치를 둔 소비로 나타났으 며, 쾌락보다는 실용성에 가치를 둔 소비로 나타났다. 소비가치 중 쾌락적 소비가치 수준이 높을수록 통계적 으로 유의미하게 소비만족도에 정(+)의 영향을 미치는 것으로 나타났다. 결론: 대학생의 안경구매에 대한 소비만족도를 높이기 위해 쾌락적 소비가치를 높일 수 있는 다양한 컨 텐츠 개발과 서비스가 필요할 것으로 사료된다.

Purpose: Aims of this study were to investigate the agreement and test-retest repeatability of two methods for measuring magnitude of soft toric lens rotation. The two methods assessed were a newly developed mobile application for iPhone which uses the built-in camera function and the slit lamp biomicroscope. Methods: Agreement of ToriExpertä against known reference source was tested under experimental situation. For clinical measurement, thirty three participants (66 eyes) wore toric lens (prism ballast design) both eyes. Two investigators measured toric lens rotation using the two methods which are slit-lamp measurement(HS-700) and mobile application. First investigator used the same method twice for assessment of test-retest repeatability of each method. Inter- and intra-investigator agreement and repeatability were assessed using Bland-Altman analysis. Results: Against the known reference sources, mean variance was 0.52±0.75 degree and limits of agreement was ±1.47 degree (95% of Cls). The limits of agreement between the silt-lamp biomicroscope and mobile application methods was ±9.1 degree (95% CIs). Measurements using the two different methods showed no statistically significant mean difference (paired t-test, p=0.32). Inter-investigator agreement of lens rotation was ±7.9 degree (95% CIs) using the slit-lamp microscope and ±7.8 degree using mobile application. Intra-investigator repeatability was ±6.6 degree using the slit lamp microscope and ±6.8 using mobile application. Conclusions: The results should be considered in view of the fact that soft toric lenses are not static but move with the blink thus the location of the reference point is unlikely to be at exactly the same location at the different measurement times. Despite this source of variability in the results, the newly developed mobile application provides clinically comparable performance to slit lamp biomicroscope measurement which does not appear to be investigator dependent. This mobile application may provide sufficient precision to those optometric practices have limited access to slit-lamp biomicroscope for measuring soft toric lens rotation.

Research in foreign accent has reported various factors of accentedness. However, very little attention has been given to the relationship between L2 speakers’ accentedness and their awareness of, or sensitivity to, L2 phonological system. The present study aims to explore the relationship between ESL learners’ phonological awareness, as measured by several tasks, and their accentedness, as rated by native speakers of English. Twelve advanced adult ESL speakers participated in seven tasks purported to tap into their sensitivity to English sounds and sound structures. They also read an English passage, and four native speakers rated their foreign accentedness on a 9-point scale. The learners showed individual differences in their phonological awareness despite the fact that they were from an intact class presumably at the same proficiency level. They also exhibited varying degrees of foreign accent. Correlational analyses revealed that in general there was a nonsignificant correlation between the learners’ L2 phonological awareness and their accentedness, and that the awareness did not seem to have translated into L2 production. The study addresses some methodological and procedural issues that suggest crucial points for refinement of the phonological awareness tasks and the L2 speech data collection method.

Anthocyanins are naturally occuring phytochemicals and the main components of the coloring of plants, flowers and fruits. They are known to elicit antioxidative, anti-inflammatory and cancer preventive activity. In this study, we investigated anthocyanins in black / yellow soybean seedcoats using different methods of detection - thin layer chromatography (TLC), capillary zone electrophoresis (CZE) and HPLC analysis. The anthocyanins in soybean seedcoats were extracted by five independent methods of extraction and the aglycons (anthocyanidins) of the corresponding anthocyanins were prepared by acid mediated hydrolysis. The anthocyanin / anthocyanidin in black soybean seedcoat showed characteristic TLC mobility, CZE electrophoretic retention and HPLC migration time while little of anthocyanins were detected from yellow soybean seedcoat. The extracted anthocyanins showed pH dependent retention time in CZE and spectral change in UV-Vis spectrum. HPLC analysis of the hydrolyzed extract of black soybean seedcoat identified the presence of four anthocyanidins. The major anthocyanin in black soybean seedcoat was cyanin (cyanidin-3-O-glucoside), with the relative order of anthocyanidin in cyanidin > delphinidin > petunidin > pelargonidin.

This study was conducted to investigate egg development and larvae morphological development of catfish and to provide basic data to clarify the genetic relationship with Siluriformes fish. The mother fish that was used in this study was caught in the stream of Nakdong River in Uiseong-gun, Gyeongbuk. The temperature range of the breeding was 23.0- 25.0℃ (mean 24.0±1.0℃) and egg size was 1.62-1.70 mm (mean 1.66±0.05, n=30). Eggs of catfish began hatching at 54 hours and 40 minutes after fertilization. Immediately after hatching, the total length of larvae was 3.60-3.65 mm (mean 3.62±0.03, n=5) and had an egg yolk without swimming ability. On the third day after hatching, the larvae at the medium stage was 8.00-8.65 mm (mean 8.32±0.45) in total length, and two pairs of whiskers formed around the mouth were elongated. On the 12th day after hatching, the larvae at the juvenile stage was 16.5-17.0 mm (mean 16.7±0.35) in total length, and the stem of each fin was in the range, and the juvenile at this period was morphologically similar to the mother fish.

피부색은 건강상태나 연령을 인식하는데 중요한 역할을 할 뿐만 아니라 선호하는 피부색에 따라 매력을 느끼는 기준이 되기도 한다. 다수의 소비자들은 자신의 피부색을 개선시키기 위해 화장품을 선택하기도 하며 이러한 수요에 따라 화장품의 종류는 다양해졌다. 최근에는 ‘하얗고 밝은 피부’에서 ‘건강하고 생기있어 보이는 피부’ 등 안색의 선호가 다양해지고 관련 표현의 효능을 표방하는 화장품이 증가하고 있지만 ‘피부색(안색) 개 선’에 대한 객관적인 평가 기준이 없어 본 연구에서는 피부색을 표현하는 형용사(complexion -describing adjectives, CDAs)를 선정하고 quasi L*a*b* 값을 이용한 통계분석 방법으로 피부색을 표현하는 형용사를 정 량화하였다. CDA 7개[‘창백한(pale)’, ‘깨끗한(clear)’, ‘화사한(radiant)’, ‘생기있는(lively)’, ‘건강한 (healthy)’, ‘불그스름한(rosy)’, ‘칙칙한(dull)’]를 선별하였고 피부색을 평가한 경험이 있는 30명의 패널이 각 각의 형용사를 밝은 피부 사진과 어두운 피부 사진의 색감에 적용하고 이를 다시 수치화하여 단어간에 통계적 유의성 여부를 확인하였다. 그 결과, 어두운 피부의 기준 이미지와 각각의 CDA를 반영한 조정 이미지, 밝은 피 부의 기준 이미지와 각각의 CDA를 반영한 조정 이미지간의 quasi L*, a*, b* 값이 통계적 유의차를 보였다(p < 0.05). 그러나 같은 CDA를 반영한 밝은 피부와 어두운 피부간에는 통계적 유의차가 없었고, 비슷한 계열의 형용사 간에 그룹화되는 경향[(i)창백한-깨끗한-화사한 (ii)생기있는-건강한-불그스름한 (iii)칙칙한]을 확인 하였다. 본 연구에서는 주관적인 느낌을 표현하는 형용사를 객관적 지표로 수치화하고 이를 통해 피부색을 평가 하는 기준으로 활용할 수 있음을 제시하고자 한다.

Prevalence of the coronary artery anomaly is approximately 1% of the population who undergo coronary angiography. The anomalous origin of the right coronary artery (RCA) as a branch of the left anterior descending artery (LAD) is a very rare variation of single coronary artery. The anatomic variation has no clinical significance. However, some patterns of congenital coronary artery anomalies can cause clinical manifestations of myocardial ischemia, reducing myocardial perfusion. We report on a case of a 78-year-old man who had anomalous RCA arising from the proximal part of the LAD, which probably caused chest pain.
