영어 사전에 나타난 한국의 모습

김경석(Kim Kyung Suk) 한국사회언어학회 2004 사회언어학 Vol.12 No.2

Kim, Kyung Suk. 2004. The Portrayal of Korea in an English-English Dictionary. The Sociolinguistic Journal of Korea, 12(2). This paper examines the sentences relevant to Korea which were found in a search of an English-English dictionary to see how they portray Korea. One hundred nineteen sentences were obtained from the CD-ROM version of Collins-Cobuild English Dictionary for Advanced Learners (2001) and they were judged as to whether they present positive, neutral, or negative images. The majority of the sentences (73/119) have neutral portrayals. Among the remaining sentences, 12 are positive and 34 are negative. When the data are sub-categorized into three groups, it becomes obvious what the positive and negative sentences in the data reflect in general. Nine positive sentences out of the total 12 positive ones are relevant to the activities/people of the Republic of Korea. Twenty-four of the negative sentences include the generic expressions of Korea referring to both South and North Korea (e.g., Korean peninsula or Koreans) or phrases referring to North Korea more explicitly. When we look more closely at the negative sentences, it is found that they are mostly related to the political tension or military conflicts between South and North, which happened quite a while ago and which we have fully recovered from. In order to prevent those sentences from leaving a potentially bad imprint on the users of the dictionary, we need to give feedback to the publisher about the results of this line of research and ask them to replace the sentences with positive/neutral sentences when they update the dictionary.

Digital infrared thermal imaging in osteoporosis

Lee, Kyung-Sub,Kim, Yong-Suk INSTITUTE OF ORIENTAL MEDICINE KYUNG-HEE UNIVERSIT 2000 JOURNAL OF ORIENTAL MEDICINE Vol.5 No.1

This study examined the relationship between bone mineral density and DITI in the diagnosis of osteoporosis. An analysis was performed on the thermographic findings of 20 patients without osteoporosis, 20 with osteopenia and 20 with osteoporosis at the Kangnan Korean Hospital, Kyung-Hee University, Seoul, Koera, from June 1998 to February 1999. The osteoporosis was measured by LUNAR PIXI and the body temperature was assessed by DITI. Thermogrphic measurements were performed on 4 areas(acupuncture point: CV12, CV4, BL23 and BL26). All data were coded for computer analysis and significances were tested by Duncan test. There was no significant diference in age among the three groups of patients. DITI revealed the significant hypothermia (p<0.001) on the osteoporosis patients compared with osteopenia and normal bone density patients. It is believed tha DITI may be a favorable alternative to diagnosis of osteoporosis.

이헌경,김승용,홍원선,민영일,정훈용,김해련,정성애,김석균,심기남,양석균,박의련,조문경 대한소화기내시경학회 1999 Clinical Endoscopy Vol.19 No.3

Background/Aims: Although some authors have suggested that sodium phosphate (NaP) is more effective than polyethylene glycol (PEG) in bowel cleansing, there has been no crossover study proving the superiority of NaP over PEG in bowel cleansing and patients' compliance. The aim of this study was to compare the two solutions for colonoscopy, PEG and NaP, through crossover design with regard to patients' compliance, cleansing ability and side effects. Methods: Thirty patients underwent two separate colonoscopies for colonic polyp(s) with PEG and NaP, respectively. Before and after bowel preparation, blood pressure, body weight, and serum biochemical parameters were measured in all patients. In addition, a detailed questionnaire was used to assess side effects and the patients' preference. The presence of bubbles, types of residual stool, and overall quality of colon cleansing were assessed by one endoscopist blinded to the type of preparation used. In each colonoscopy, two biopsy specimens were taken at rectum. Results: In the NaP group, but not in the PEG group, there were significant changes in several biochemical parameters including sodium (+3.0±3.0 mEq/L), potassium (-0.3±0.3mEq/L), calcium (-0.5±0.5 mg/dL), phosphorus (+3.9±2.2 mg/dL) and osmolarity ( +10.1±9.3 mOsm/kg) after bowel preparation. In addition, the degree of body weight change was greater with NaP (-2.2±2.3 kg) than with PEG (-1.2±2.0 kg) (p=0.06) and the formation of bubbles that disturb luminal observation was more frequently found in the NaP group (p$lt;0.01). There was no difference, however, in the type of residual stool and the overall quality of bowel preparation between the two groups and no significant mucosal change was noted after bowel preparation in both groups. Moreover, PEG was found to be more difficult to take than NaP (p$lt;0.05) and among the 30 patients, 26 (87%) preferred NaP, while only two favored PEG (p$lt;0.01). Conclusions: We conclude that NaP can replace PEG at least in patients with good general condition. Further studies to decrease the incidence of bubbles and to establish subgroups suitable for NaP are needed.

Purpose: The purpose of this descriptive study was conducted to investigate the health condition and satisfaction for health examination of students in elementary school. Method: The subjects for this study were 113 students, from an elementary school in W, Kyung-Buk Province. The health condition and satisfaction Questionnaire made by Kyung-Buk Education Office(2007) and modified by authors of this study were used to measure health condition and satisfaction. The data were collected from Dec. 21 to Dec. 13, 2009 using questionnaire with self reported and records of the school health. Data was analysed by x 2-test, independent t-test and ANOVA with SPSS WIN 17.0. Result: There were no statistically significant differences in the reported satisfaction scores of elementary school children regarding health examinations either by gender (male: 40.13 ± 3.90, female: 39.95 ± 4.50)or economic conditions (low: 41.00 ± 2.3, upper: 40.53 ± 4.9, middle: 39.66 ± 4.1). Conclusion: The findings in this study did not support differences in satisfaction scores either by gender or level of income relative to health examination. Future research may utilize a qualitative approach to explore differences among school.

In this Paper, a back propagation neural network learning algorithm based on the complex multilayer perceptron is represented for controling and detecting interference of the received signals in DS/SS mobile communication system. We propose a new fixed bit rate controller method using neural networks to improve in transmitting a received signal source through a constant rate channel. The proposed fixed bit-rate controller proposed consists of the three-layered fully connected neural network with 16 input, 6 hidden, and 3 output nodes. Back propagation algorithm is used for learning of the neural network. The training data include various factors that influence the generation of bit rate in an detector. The results of simulation show that the proposed algorithm is superior to the conventional one for picture quality and bandwidth utilization aspects. We analyzed and proved that receive using neural network has lower bit error probability than that of traditional Matched Filter receiver through results of computer simulation in the presence of the tone and narrow-band interference and the co-channel interference.

Chiral titanium complex prepared in situ from (IR, 2S)-norephedrine-N-mesitylsulfonamide and dichlorodiiosopropoxytitanium was used as catalyst in the enantioselective hydrocyanation of several aldehydes with trimethylsilycyanide. The reactions were carried out using 20mol% of catalyst compared to substrates. In addition, (IR-2S)-norephedrine-N-mesitylsulfonamide was proved to be an effective chiral auxiliary in asymmetric cyanosilylation.
