Today people`s interest on scalp and hair care is growing, and everyone use shampoo for hair washing. But the most of them do not know right shampooing time. In this study, basic data on the contents of sebum·moisture and keratin after shampooing were investigated on normal scalp. The level of sebum·moisture and keratin at frontal, left and right temporal regions, and occipital region in 5 volunteers in 20`s age were measured respectively before shampooing, and 30 minutes, 2, 4, 6, 10, 12, 16, 20, 24 hours after shampooing, and also observed the condition of scalp with gross observation and light microscope. As a result, it was found that the contents of sebum before shampooing, it decreased significantly (p<0.05) from 30 minutes to 20 hours after shampooing, and the contents of sebum became similar after 24 hours. The moisture amount of moisture before shampooing, it increased from 30 minutes to 4 hours after shampooing, while decreased in some parts significantly (p<0.05) until 20 hours after shampooing, and the contents of moisture became similar after 24 hours after shampooing. Regarding the contents of keratin before shampooing, it increased from 30 minutes to 4 hours after shampooing, while decreased in some parts significantly (p<0.05) until 20 hours after shampooing, and the contents of keratin became similar after 24 hours. Unaided-eye observation on scalp before shampooing found that sebum was abundant throughout the entire scalp regions, and stuffy pores and expansion of capillary vessel due to lipid peroxide formed by sweat, sebum, and dusts was observed. Considering the observation of the contents of sebum·moisture and keratin on normal appropriate interval between shampooing is found to be about 24 hours, and the finding can be valuable basic data that people can apply in hair·scalp cleansing and care.

현대중국어고빈도동사의윤곽과토대에관한연구 ― 고빈도 동사 ‘開’를 중심으로

朴懦賢(Park, Na-hyun) 중국어문학연구회 2022 중국어문학논집 Vol.- No.134

This study was conducted to define the various meanings of the modern Chinese polysemous verb “开” based on semantic profile and base of verb from the perspective of cognitive linguistics and presents a schematic for how these meanings are connected and have changed over time. This paper is divided into four parts: 1) The cognitive linguistics concepts of profile and base are based on the perceptual psychology concepts of appearance and foundation, respectively. Perception is the consciousness of the entire image of an object caused by the stimulation of the sensory organs. It is also defined as a basic stage of recognition of objective reality through direct and emotional simulation. 2) In order to analyze the combination conditions of the verb “开,” first data about “开x” was collected based on the heading characters of the verb “开” included in the Modern Chinese Dictionary (7th Edition). Out of a total of 195 heading characters, only “verbs” were selected based on modern standard Chinese and the semantic roles of “开” were classified. Data about “x开” were targeted for 18 vocabulary words, including the predicative components searched at high frequency in the heading characters and the corpus presented in the Modern Chinese Reverse Dictionary (2011). Based on this data, the following six semantic profiles were generated: separation, open, expansion, start, movement, and appearance. 3) Frequently used polysemous verbs become multilingual through metaphor or metonymy. This study examined what mechanisms are used and how it is involved when the verb “开” is involved in the process of expanding meanings. The separation and open categories reflected the cognitive effects of metaphor while the expansion, start, movement, and appearance categories showed the cognitive effects of metonymy. 4) Finally, the profile category of each example was defined according to the semantic qualities of the patterns in which words in those categories combined with the polysemous verb “开.” An abstract image schema was implemented by dividing the profile and base based on the words from which the meanings were derived.

박나현(Park, Na-Hyun),김혜연(Kim, Hye-Yun),곽기섭(Gwak, Ki-Seob),구본욱(Koo, Bon-Wook),어환명(Yeo, Hwan-Myeong),최인규(Choi, In-Gyu) 한국신재생에너지학회 2009 한국신재생에너지학회 학술대회논문집 Vol.2009 No.11

The object is to optimize the best condition of organosolv pretreatment process with sulfuric acid as a catalyst. As a material, Pitch pine (Pinus rigida) was ground and sieved through 40-mesh screen, and Celluclast and beta-glucosidase were used as enzymes for enzymatic hydrolysis. Pretreatment processes were carried out in the minibomb, and 20 g of materials with 200 ml of 50% ethanol solution (v/v) with 1% sulfuric acid as a catalyst. Pretreatment temperature was varied from 150?C to 190?C, and time was varied from 0 to 20 min. Then, residual materials were used for enzymatic hydrolysis. The best conditions were selected by estimating followed enzymatic hydrolysis rate and degradable rates after pretreatment process. The highest value of enzymatic hydrolysis rate was obtained as 55 - 60% at 160 and at 180?C, but the value decreased under more severe conditions. As the residual rates decreased under severe conditions, it infered that the decrease of sugar contents limits enzymatic hydrolysis rates. Combined with enzymatic hydrolysis rate, degradable rates and H-factors, the temperatures at 160?C for 20 min and at 180?C for 0 min were concluded as the optimized conditions where have the lowest H-factor value for considering energy input.

로봇이 사람과 같이 다양하고 복잡한 사물 조작을 하기 위해서 휴먼형 로봇손의 사물 파지 작업이 필수적이다. 자유도 (Degree of Freedom, DoF)가 높은 휴먼형(anthropomorphic) 로봇손을 학습시키기 위하여 사람 데모(human demonstration)가 결합된 강화학습 최적화 방법이 제안되었다. 본 연구에서는 강화학습 최적화 방법에 사람 데모가 결합된 Demonstration Augmented Natural Policy Gradient (DA-NPG)와 NPG 의 성능 비교를 통하여 행동 복제의 효율성을 확인하고, DA-NPG, DA-Trust Region Policy Optimization (DA-TRPO), DA-Proximal Policy Optimization (DA-PPO)의 최적화 방법의 성능 평가를 위하여 6 종의 물체에 대한 휴먼형 로봇손의 사물 조작 작업을 수행한다. 그 결과, DA-NPG 와 NPG를 비교한 결과를 통해 휴먼형 로봇손의 사물 조작 강화학습에 행동 복제가 효율적임을 증명하였다. 또한, DA-NPG 는 DA-TRPO 와 유사한 성능을 보이면서 모든 물체에 대한 사물 파지에 성공하여 가장 안정적이었다. 반면, DA-TRPO 와 DA-PPO 는 사물 조작에 실패한 물체가 존재하여 불안정한 성능을 보였다. 본 연구에서 제안하는 방법은 향후 실제 휴먼형 로봇에 적용하여 휴먼형 로봇 손의 사물조작 지능 개발에 유용할 것으로 전망된다.

문학교육 연구의 주제와 방법에 대한 메타 점검-<문학교육학> 발표 논문을 중심으로-

김지남 ( Ji Nam Kim ),박나현 ( Na Hyun Park ),김창원 ( Chang Won Kim ) 한국문학교육학회 2015 문학교육학 Vol.48 No.-

본고는 한국문학교육학회의 정기 학술지인 『문학교육학』1호(1997)~46호(2015) 중 매년 1권씩 18권을 무작위 선택하여, 거기에 실린 논문 230편을 대상으로 문학교육 연구의 주제와 방법을 분석하였다. 먼저 주제 분석을 위해 연구의 목적과 내용에 나타난 문학 요소와 교육 요소를 중심으로 논문들을 <문학 원론, 장르, 문학사, 작가ㆍ작품, 수용ㆍ생산>과 <문학교육 원론, 교육과정, 교재, 교수ㆍ학습(자), 평가>를 축으로 한 분석 틀에 분류, 배치하였다. 그리고 방법 분석을 위해 문학ㆍ텍스트 지향 방법론과 교육ㆍ활동 지향 방법론, 종합적 방법론을 대범주로, <구조론적 접근, 수용ㆍ생산론적 접근, 반영론적 접근>과 <이론 연구, 모형 연구, 실행ㆍ실험 연구>를 소범주로 한 분석 틀을 만들고 거기에 논문들을 분류, 배치하였다. 이 결과를 활용하여 논문들의 주제와 방법을 분석하여 문학교육 연구 전반의 특징과 성과, 한계를 살펴본 것이 본고의 내용이다.『문학교육학』발표 논문을 중심으로 문학교육 연구의 성과를 살펴본 결과 문학 비평의 이론을 교육적으로 전화(轉化), 적용하는 데에는 많은 성취와 진보가 있었음을 알 수 있었다. 아울러, 학회의 기획 주제를 통해 문학교육에 대한 관심이 ‘문학’에서 ‘인간’으로 변해 온 과정도 알 수 있었다. 그럼에도 불구하고 문학교육의 중요한 변인인 인간(주체) 요인을 다룬 연구가 적고, 사회과학적 방법론에 입각한 연구, 특히 실행ㆍ실험 연구가 소략하다는 특징도 발견되었다. 이러한 경향성은 선행 연구 등을 통해 충분히 예측되었던 바, 본고는 예측의 단순 확인을 넘어 그 세부의 내용적ㆍ방법적 체계를 정밀하게 분석함으로써 보다 실증적이고 비판적인 논의까지 밀고 나간 의의를 지닌다. 아울러, 이를 통하여 문학교육 연구의 방향에 대한 숙고도 이루어질 수 있다. This paper focuses on analyzing the trends and features of research on Korean literature education through surveying results from the first publication of Journal of Korean Literature Education Research until now, and then inducing further research issues and goals. 586 papers have been published after the first publication of JKLE that has latest version of the 46th publication in 2015. It has big contributions to establish an academic identity of Korean literature education. The specialization field in literature education has been searched not under the premise of simple summation of literature and education but under various aspects and practical levels. It bring to needs for further literature education developments with analysis and evaluation of these research achievements. We classified and analyzed randomly selected 230 papers published in JKLE and those selected papers are evenly distributed through the years. Analysis of the results found that academic achievements in Korean literature education. However, we found out that researches on human factor, main subject in literature education, is relatively less. It means that the topics and methods of research on Korean literature education is affected more literature theory than educational theory, and research strategy for searching its own special area is focused on literary contents. In this paper, we have a contribution to suggest the development direction of research on Korean literature education based on surveying achievement of accumulated researches. It support this paper critical meta-data analysis of research on Korean literature education because it is acquired from empirical reviews.
