Choi, Kyung-Ae. 2002. [t]~[s] alternation in Korean loanwords. Studies in Phonetics, Phonology and Morphology. 8-2. 289-302. The purpose of this paper is to examine the controversial phenomenon [t]~[s] alternation which apprears when the lexicalized loanwords undergo nativization and analyze it in the framework of Optimality Theory. For this analysis. I preview vowel epenthesis phenomenon which is related to [t]~[s] alternation. The alternation should be explained by the consonant weakening process rather than the reanalysis of /t/ into [s] and by the interaction of the constraints OWC Max-IO(Feature) and PAL.

A study on the unexpected phonological change in the English loanwords in Korean from Japanese

Choi,Kyung-ae 한국사회언어학회 2012 사회언어학 Vol.20 No.1

Choi, Kyung-ae. 2012. A study on the unexpected phonological change in the English loanwords in Korean from Japanese. The Sociolinguistic Journal of Korea 20(1). pp. 295-315. The purpose of this study is to inquire about sound change by tracing the transition of English loanwords in Korean, which came from Japan, from phonological and sociolinguistic perspectives. The Japanese-style English loanwords from an earlier period have been transformed into newly adjusted forms at a surprisingly rapid rate and many of them have shown unexpected sound changes which went against general Korean phonological rules. This shows that sound change is not necessarily expected to occur in accordance with language-specific phonological rules. It can occur through the political and sociological will of speakers against their native grammar at a surprisingly rapid rate.

The Anti-cancer Effect of Oriental Medicine Chung-Ri-Ja-Gam-Tang in the Mouse with Metastatic Lung Cancer. Proceedings of International Symposium on East-West Medicine, Seoul. 231-243, 1999.-The oriental medicine Chung-Ri-Ja-Gam-Tang is an herbal medicine which has been used for pulmonary diseases and known as having immune stimulatory effects. It has been known effective in lung cancer. So we studied the effects and the mechanisms of this herbal medicine it the mouse with metastatic lung cancer. The metastatic lung cancer of the mouse was produced with melnoma cell line(B16BL/6).5×10□/mouse tumor cells were injected intravenously to the CDF1 mouse via tail vein. The mice were divided 4 groups. The first group was treated with 50mg/kg extract of Chung-Ri-Ja-Gam-Tang per oral for 10 days after cancer cell injection, second group treated with saline after cancer cell injection, the third group with medicine without cancer cell, and the last group with saline only. After 10 days treatments some of the mice were scarificed and the lung and spleen was removed. The survival duration, weight change, the number of metastatic cancer nodule of the lung, the NK cell activity, the capacity of cytokines(INF-γ,INF-α,IL-2) production and the proliferation activities of mouse lymphocytes were measured. The surival times of the group 1 mice were longer and the weight loss was less than the group 2 significantly. The number of the metastatic nodule of the lung were decresed in the group 1 than the group 2. The production of INF-γ,was increase in group 2 than group 3 and 4, IL-2 production was increased in group 1 than group 2,3,4 significantly. There was no difference in TNF- α production and proliferation activity of lymphocyte in each group. The NK cell activity was significantly increased in group 1 than group 2,3,4. We conclude that the Chung-Ri-Ja-Gam-Tang has the effect of increasing the NK cell activity of the CDF1 mouse with metastatic lung cancer(B16BL/6). And it is suggested that the increased production of the IL-2 is the mechanisms of enhanced NK cell activity.

박경리의 『애가』를 통해 본 멜로드라마, 젠더화된 사랑, 그리고 연민

최경희(Choi Kyung-hee) 한국비평문학회 2023 批評文學 Vol.- No.90

박경리의 『애가』(哀歌)』(『민주신보』,1958)는 작가가 본격적으로 장편을 창작하기 위해 자신의 역량을 시험한 첫 작품이자 박경리 문학 세계의 원형을 지닌 소설이다. 그럼에도 『애가』는 몇몇 작품들과 함께 협소하게 연구되어 왔다. 무엇보다 『애가』는 초기 단편에 나타난 사랑과 결혼을 둘러싼 여성 정체성 문제를 밀도있게 그린 소설이다. 뿐만 아니라 60년대 박경리 장편들에서 다양하게 변주된 젠더화된 사랑의 시발점을 보여준 소설이다. 다시 말해 『애가』는 사랑과 결혼이라는 멜로드라마적 소재를 통해 대중성을 확보하면서도 전후 사회의 젠더 인식을 묘파한 60년대 장편들의 특징을 처음으로 구현한 소설이다. 본고는 『애가』가 결혼 장애와 불륜 등의 멜로드라마적 전개를 통해 개인의 사랑과 욕망이 사회 규범과 갈등하는 양상을 이야기하는 가운데 젠더 인식의 시대적 코드를 구현한 점에 주목하였다. 또한 사랑과 결혼을 둘러싼 인물들의 젠더인식에 내재한 인간의 고독과 그에 대한 연민을 살펴 보았다 Aega by Park Kyung-ni is the first work the author tested her capacity to create an earnest full-length novel and is the fiction with an archetypal character of her literary world. Yet, Aega has been studied in a limited manner along with a few other novels. Above all else, Aega is not only a novel that expanded the issue of female identity around love and marriage shown in her early short novels but also one that exhibited the starting point of gendered love variated in different ways in her full-length novels in the 1960s. In other words, Aega secured popular appeal through the romantic material of love and marriage, and simultaneously, embodied the characteristics of full-length novels in the 1960s that openly portrayed the gender perception of postwar society for the first time. This paper focuses on such aspects and analyzed how Aega realized the codes of times of gender perception while discussing the patterns of an individual’s love and desires conflicting with social norms through melodramatic development such as marital barriers and adultery. In other words, it analyzed the gender perception of characters concerning love and marriage. Moreover, the paper reviews the novel as the first full-length novel that materialized human solitude and compassion and solidarity for it, which are the traits of Park Kyung-ni’s literature.

The purpose of this study was to investigate cardiovascular responses to a bout of aerobic exercise and acute smoking cessation in smoker. nine collegiate male smoker who have been smoking(duration of smoking: 7.5 ± 0.9yrs; number of cigarettes per day: 15.5 ± 1.5) participated in this study. All subjects performed PEI to stimulate Group IV metaboreceptor at immediately after smoking, 24hours after smoking cessation and smoking after a bout of aerobic exercise. they were measured SBP, DBP, HR, SV, CO, TVC using by finometer(FMS co, Netherland). As a result, compared to immediately after smoking, SBP, DBP, and MAP were significantly decreased 24-hours after smoking cessation at rest and PEI(p<0.05). In addition, smoking after a bout of aerobic exercise caused by post-exercise hypotension indicated that SBP was significantly decreased compared to immediately after smoking(p<0.05). also, the changes in DBP and MAP at rest and handgrip exercise were significantly smaller compared to immediately after smoking(p<0.05). Thus, the results showed that smoking cessation during 24-hours and a bout of aerobic exercise relieve excess blood pressure response and enhanced arterial baroreflex in collegiate male smoker. It is concluded that caused exercise pressor reflex by stimulated Group IV may be effective to improve excess blood pressure responses.

This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exercise habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

팔당호의 생태학적 환경요인의 계절적인 변화를 분석하므로서 이것으로 인한 식물성 플랑크톤의 연관성을 고찰과 함께 오염과정을 파악하여 수질오염의 예방의 기초자료를 얻고자 본 실험을 수행하였다. 1994년 4월부터 1995년 10월까지 계절별로 3개 지점에서 시료를 채취하여 표층부와 저층부의 수질을 분석하였다 용존산소(DO)와 pH는 각각 7.0-11.6 ㎎/ℓ와 6.9-8.9의 범위이었으며 COD와 BOD농도는 각각 1.6-4.8 ㎎/ℓ와 0.8-2.9 ㎎/ℓ이었으며,SS는 1.8-8.6 ㎎/ℓ의 농도차를 보여 주었다. 또한 NH₃-N와 PO₄-P의 농도는 각각 0.161-0.478 ㎎/ℓ와 0.003-0.073 ㎎/ℓ이었다. 표층의 chlorophyll a의 농도는 낮게는 북한강 유입부위인 12.3 ㎎/ℓ로부터 가장 높은 경안천 유입부위 23.8 ㎎/ℓ의 범위를 보여주고 있다. pH,전도도, COD, BOD, SS ,총인, chlorophyll a의 농도는 하계절에 가장 높았으며 이 결과로 미루어 보아 하계절에는 하천에 오염물질이 가장 많이 유입되는 것으로 추정된다. Station별로 조사한 결과 이들의 농도는 경안천 하류인 St. 3가 남한강 하류인 St. 2이나 댐지역의 St. 4보다 높은 결과를 보여 주었으므로 경안천 상류에서 오염원이 가장 많이 유입되는 것으로 추정된다. 아울러 종속영양세균의 분포도 경안천이 다른 지역보다 가장 높게 나타났다. Seasonal variation of water quality was examined in the reservoir, lake Paldang on Han River, the inlet stations from three rivers, North Han River, South Han liver, Kyung-An stream, and the station of dam area of the lake. Water samples were collected bimonthly from surface and bottom layers at four different stations of the lake Paldang from April 1993 to August 1994. With respect to the seasonal variation, pH, conductivity, and concentrations of COD, BOD, SS, total phosphorus, and chlorophyll a were higher in summer compared with those of autumn or other seasons, while concentrations of DO, NH₃-N, and PO₄-P were increased in winter. Concentrations of COD, BOD, chlorophyll a, total nitrogen and phosphorus were the highest at the station of Kyung-An stream rather than those of other three stations. The average concentrations of chlorophyll a surface water were from 12.3 ㎎/ℓ at North Han River to 23.8 ㎎/ℓ at Kyung-An stream. Heterotrophic bacterial distribution showed higher at the station of Kyung-An steam than those of South Han River and the dam station of the lake.

Under the pressure to open the service market as proposed by World Trade Organization, we can easily expect our educational systems for allied health professions will experience a lot of changes in near future. Accordingly, we compared our current educational systems for allied health professions with the foreign ones and mapped out some strategies predicting the forthcoming enormous changes. Major investigations and analysis are summed up as follows, The educational programs for allied health professions which was started in 1963 in Korea are stilled remained as 2 to 3 school years, while the systems in advanced countries have already been changed or been changing from 2 year to 4 year college levels. We can hardly find the uniform educational system or school years for the allied health professions in the world except for Korea. Fortunately, university level four-year programs for the profession was established in 1979 in Won-joo for the first time in Korea. However, there are still only few four-year programs in this country. To meet the rapidly changing needs we have faced in the health areas we should supply appropriate health personnel through various efforts. Now we would like to suggest followings, <Educational goals for the allied health professions> 1) reconfirming characteristics for the educational goals of health professions 2) extending school years for the allied health professions 3) strengthening clinical training and internship 4) expanding opportunities for the continuing education through lifelong education 5) upgrading from old-fashioned technologies to advanced technologies 6) cultivating competencies of health professionals for the global competition <Suggestions for the Development of Allied Health Professions> 1) reforming the school years of educational programs for the allied health professions to meet the global standards 2) expanding the role of junior college programs for the allied health professions through the development of intensive courses in the professions. 3) diversifying and specializing the allied health professions mainly through 4 year B.S. degree programs.

중학교 과학 수업에서 교사와 학생의 언어적 상호작용 분석

최경희,박종윤,최병순,남정희,최경순,이기순 한국과학교육학회 2004 한국과학교육학회지 Vol.24 No.6

이 연구의 목적은 중학교 과학 수업에서 교사와 학생간의 언어적 상호작용이 실제로 어떻게 이루어지고 있는지를 관찰ㆍ분석하여 이에 대한 특징을 추출함으로써 과학 수업에서 교사와 학생간의 언어적 상호작용에 대한 기초 자료를 제공하는데 있다. 이를 위해 수업 분석 준거를 개발하였으며, 8명의 과학 교사의 수업 12차시를 관찰 및 녹화하였으며, 교사와의 면담을 실시하였다. 수업 분석 결과, 관찰한 과학 수업에서 교사와 학생간의 언어적 상호작용은 주로 교사의 단순 확인/기억 질문, 학생의 단답형 응답, 교사의 즉각적 피드백이 주를 이루었다. 교사가 사고 질문을 하고 지연 피드백을 부여 하는 경우 학생들이 자신의 생각을 드러내고 이를 기반으로 사고를 진전시켜 나갈 수 있었으나 이러한 사례는 그 수가 상당히 적었다. 교사들은 학생들의 사고를 유발하고 이를 진전시키기 위한 노력보다는 수업 내용을 논리적 흐름에 맞추어 체계적으로 제시하는 것에 더 큰 중점을 두는 경향이 있었다. 또한 관찰한 수업에서 교사가 시범 실험, 모형 혹은 실물 수업자료 등을 활용할 때 보다 많은 수의 학생들이 적극적으로 수업에 참여하여 자신의 생각을 드러내었으나 교사가 학생들의 생각을 바탕으로 학생들의 사고과정을 진전시켜 나가는 과정을 도모하지 않음으로써 학생들의 사고과정을 단절시키는 경우가 많았다. 따라서 수업 활동과 수업 자료 활용이 효과를 거두기 위해서는 각각의 활용에 있어서 학생들과 구체적으로 어떠한 상호 작용을 형성해야 하는지에 대해 연구가 이루어져야하며, 또한 교사는 교사의 질문이나 피드백이 학생들의 학습에 중요한 역할을 함을 인식해야 한다. The purpose of this study is to analyze verbal interaction between teachers and students in order to collect qualitative data on the characteristics of the interaction to enhance teaching efficacy. Total of 12 classes of eight science teachers were observed and were interviewed. The classes were video taped and all the verbal interactions were transcribed. The transcribed content and interviews were further analyzed to draw any conclusions on the verbal interaction between teachers and students. Analysis criteria for the data on the class and interview were developed based on the literature review and applied to analyze the collected content. The analyzed data showed that verbal interactions composed of confirmation questions for memorization, students' short responses and teacher's immediate feedbacks. The results of the study also suggested that there needs to be further studies on the interactional techniques for teacher in utilizing the class materials and activities. The teachers should acknowledge the importance of the questions and feedbacks of teachers for students to stimulate their sound learning through literatures.

Purpose : This study was designed to determine a proper threshold value and opacity in three-dimensional CT volume rendering of oral and maxillofacial area. Materials and Methods : Three-dimensional CT data obtained from 50 persons who were done orthognatic surgery in department of oral and maxillofacial radiology of Seoul National University retrospectively. 12 volume rendering post-processing protocols of combination of threshold (100HU, 150HU, 221HU, 270HU) and opacity (58%, 80%, 90%) were applied. Five observers independently evaluated image quality using a five-point range scale. The results were analyzed by receiver operating characteristic curves, ANOVA and Kappa value. And three oromaxillofacial surgeons chose the all images that they thought proper clinically in the all of images. Results : Analysis using ROC curves revealed the area under each curve which indicated a diagnostic accuracy. The highest diagnostic accuracy appear with 100HU and 58% opacity. and the lowest diagnostic accuracy appear with 221HU and 58% opacity that are being used protocol in department of oral and maxillofacial radiology of Seoul National University. But, no statistically significant difference was noted between any of the protocols. And the number of proper images clinically that chosen by three oromaxillofacial surgeons is the largest in the cases of protocol 8 (221HU, opacity 80%) and protocol 11 (270HU, opacity 80%) in one after the other. Conclusion : Threshold and opacity in volume rendering can be controled easily and these can be causes of making an diagnostic accuracy. So we need to select proper values of these factors.
