조희문(Cho Hee Moon) 한국영화학회 2006 영화연구 Vol.0 No.29

Between the year of 1924 and 1943, 3 'Cho-sun Kinema' film companies has established and made each own Films. Firstly cho-sun kinema co. has opened in 1924 at Busan, the second big city of korea,. Joined by local big shots including a monk, a medical doctor, a gun shop owner. and that company made four films like 'the tragedy of the sea' 'the lover of the king' 'the make up of the God' Second one is cho-sun kinema production opened at seoul, the capital of korea. in 1926. The owner of company was a business man who runned 'the Yotoya', a hat shop. That company has made 6 films including 'Arirang' 'The Drifting Hero'. and soon became most popular and influential film company at that time, but internal conflict between Na woon gyu, the Star of the company, and other members. Third one was cho-sun kinema co. Known as another new company with cho-sun kinema production. Actually that company was same company of cho-sun kinema production. After several conflict between the Membersof that company, the company has changed system, a private owned to a joint stock company. so new cho-sun kinema co. is sequel of cho-sun kinema production.

본 연구에서는 한방이화주의 피부 생리기능 활성을 알아보기 위해 70% EtOH 추출물의 피부 미백, 주름 개선 및 항염증 효과를 조사하였다. HEE은 tyrosinase 활성 억제 및 tyrosine을 기질로 melanin이 형성되는 pathway에 관여하는 주요한 인자인 TRP-1과 TRP-2를 저해하는 작용 기전을 통해 피부 색소침착의 주요 원인 물질인 melanin 생합성을 농도 의존적으로 저해하는 것을 확인하였다. HEE은 피부진피 내 피부 탄력을 유지하는 elastin을 분해하는 효소인 elastase의 활성을 저해하였고, 피부의 keratinocyte가 생성분비하는 MMP-2와 MMP-9의 단백질 발현과 proteolytic 활성을 억제하여 노화에 따른 피부 주름 생성 억제할 수 있는 가능성을 확인하였다. 또한 세포 독성 없이 LPS에 의해 유도된 염증 반응을 50% 저해하는 HEE의 농도(IC50)는 24.9 μg/mL이며, 50 μg/mL 농도로 처리하였을 때 염증 반응 저해 효과가 70%로 높은 효과를 가지는 것을 확인하였다. 이상의 결과를 종합하면 HEE의 피부 미백, 주름 개선 및 항염증에 우수한 효과를 나타내고 있으므로 기능성 화장품의 주요한 소재로 이용 가치가 높을 것으로 사료된다. Extrinsic skin aging is characterized by the loss of skin tone and resilience, irregular pigmentation, and deep wrinkles. The aim of this study was to investigate the effects of Ehwa Makgeolli containing oriental herbs (Glycyrrhiza uralensis Fisch., Lycium chinense MILL., Morus alba L., and Saururus chinensis Baill) on skin whitening and wrinkling in human skin cells. We prepared Makgeolli extracts (HEE) with 70% ethanol. HEE significantly inhibited in vitro mushroom tyrosinase activity and reduced the cellular and secreted melanin content of mouse melanoma melanocytes (B16F1 cells). HEE down-regulated the protein expression of tyrosinase related protein (TRP)-1/-2, a key player in melanogenesis. Treatment with HEE in human keratinoctyes (HaCaT cells) inhibited the proteolytic activities of matrix metalloproteinase (MMP)-2/-9 in a dose-dependent manner and dramatically reduced the expression of MMP-2/-9. In addition, HEE attenuated lipopolysaccharide (LPS)- induced nitric oxide production in murine macrophages (RAW264.7 cells). These results indicate that HEE may be a great cosmeceutical ingredient for its whitening, anti-wrinkle, and anti-inflammatory effects.

Interleukin-21 is a common γ-chain cytokine that controls the immune responses of B cells, T cells, and natural killer cells. Targeting IL-21 to strengthen the immune system is promising for the development of vaccines as well as anti-infection and anti-tumor therapies. However, the practical application of IL-21 is limited by the high production cost. In this study, we improved IL-21 production by codon optimization and selection of appropriate signal peptide in CHO-K1 cells. Codon-optimized or non-optimized human IL-21 was stably transfected into CHO-K1 cells. IL-21 expression was 10-fold higher for codon-optimized than non-optimized IL-21. We fused five different signal peptides to codon-optimized mature IL-21 and evaluated their effect on IL-21 production. The best result (a 3-fold increase) was obtained using a signal peptide derived from human azurocidin. Furthermore, codon-optimized IL-21 containing the azurocidin signal peptide promoted IFN-γ secretion and STAT3 phosphorylation in NK-92 cells similar to codon-optimized IL-21 containing original signal peptide. Collectively, these results indicate that codon optimization and azurocidin signal peptides provide an efficient approach for the high-level production of IL-21 as a biopharmaceutical.

황명석,조창희,박종희,Whang, Myung-Suk,Cho, Chang-Hee,Park, Jong-Hee 한국생약학회 2000 생약학회지 Vol.31 No.2

'Ha Go Cho (夏枯草)' is one of the Chinese crude drugs used mainly as a diuretic. With regard to the botanical origin of 'Ha Go Cho', it was reported by Su et al. that those from China were originated from the fruited spica of Prunella vulgaris L. of Labiatae. It was, however, for the herba or spica of Prunella vulgaris L. var. lilacina Nakai from Korea. According to survey of markets in Korea, most of the materials collected in the markets seemed to be originated from Prunella plant, while some seemed to be Thesium plant of Santalaceae. To clarify the botanical origin of 'Ha Go Cho', the anatomical characteristics of Prunella vulgaris L. var. lilacina Nakai and Thesium chinense Turcz. were studied. As a result, it was clarified that some 'Ha Go Cho' from Korea were the herba or spica of Prunella vulgaris var. lilacina, whereas some others were the herba of Thesium chinense.

As a nursing practice involves nurses' actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives, Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal) ; excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, account- ability and commitment(4 theories of nursing ethics) ; human respect. partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences. positive perspectives(4 theories of nurse), role of intervention. rewarding peer relationship(3 theories of situations) The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore. it is recommended to review the theories-in-use in order to and any discrepancies between the espoused theories and the reality of nursing actions

Purpose : The purpose of this study was to identify needs of health education of the students, parents, general teachers, and health teacher of the elementary, middle, and high schools. Method : 279 schools of elementary, middle, and high school were sampled nonproportionally during the period from June 28 to July 26, 2004 . The data were collected by the questionnaire from 1,888 students, 1,876 parents, 1,695 general teachers, 279 health teachers. A frequency, % and χ2-test were used to analysis by SAS program. Result : 1. It showed that 98.1% of elementary school students, 92.3% of middle school students, 89.6% of high school students answered that they need health education. The most of students, parents, and general teachers had high interests in health education. 2. In the case of students, main causes of needs of health education was 'to prevent diseases or accidents''. But parents answered that it was 'to build up a healthier behavior'. General teachers answered that it was 'more effective systematic and continuous health education'. 3. Over 80% of students, parents, and general teachers about the question of who qualified person is to teach health education as a regular class responded that health teacher is available. Especially 93% of elementary school students answered like that. 4. The most of students, parents, and general teachers answered that health education in the classroom is favorable 1 to 2 hours per week. Conclusion : As results of the study , the majority of students, parents, general teachers agreed needs of health education. Therefore, on the basis of this study, systematic and continuous health education is necessary. Additionally the establishment of independent health subject is required certainly.

Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through x^(2)­test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teacher. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC that those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.

On Sloppy-Like Interpretation of Null Arguments

( Hee Don Ahn ),( Sung Eun Cho ) 경희대학교 언어정보연구소 2011 언어연구 Vol.28 No.3

This paper aims to show that what are considered to be apparent sloppy readings in the null argument construction in Korean and Japanese are well accounted for under Ahn & Cho`s (2009, 2010, 2011b,c) pro analysis. The environments where such readings arise are categorized into five types. First, the antecedent noun includes either a reflexive possessor or a numeral quantifier. Second, the antecedent noun is a universal quantifier. Third, the antecedent noun includes a reflexive possessor and it denotes plural entities. Fourth, the antecedent is a negative polarity item. Fifth, the antecedent itself is a reflexive pronoun. By exploring these five cases, we show how far the possible interpretation of pro is stretched. We also show that our pro analysis is conceptually superior to the one that assumes an additional parameter plus pro drop parameter such as the agreement parameter that correlates with the presence or absence of DP ellipsis.
