In an aging society, there is an increasing possibility of the duplication of the drugs given to patients because they take many kinds of drugs. Among the prescriptions given to the patients who was treated at multiple ambulatory clinics in St. Mary's hospital for one month of September, 2002, in which drugs that has identical or similar effects are prescribed, we analysed and evaluated them by patients' characteristics, kinds of medication, severity of side effects on a case by case basis. More, we assessed the potential additional costs. As a result of this study, the duplication rate turned out to be 6.69% and it was shown that the proportion of the elderly patients over 60 was high. The gastro-intestinal medications took up a large part and most of the cases showed that the danger caused by double taking of medicine was slight, but there were some examples in which the serious side effects were predicted. Expected additional costs were the average 11.349 won and it ranges from the minimum of 56 won to the maximum of 135,720 won. In conclusion, the management of drug histories of the patients who need the plural treatments is very important and the necessity of the individual and professional guidance of taking medicines for the elderly patients is emerged, too.

Their important trait is creative problem solving ability in science. Creative problem solving ability is defind as 'the ability which utilizes general knowledge and skill, specific knowledge and skills, task commitment by activate the interaction between logical thinking and divergent thinking'. The test items covers such content areas (physics, chemistry, biology, and earth science); science process (observation, classifying, measuring, predicting, inferring, identification of problem, hypotheses formation, controlling variables, converting data, interpreting data, drawing conclusin, generalization); creativity factors (originality, fluency, flexibility, elaborateness). The test consist of multiple choice type 15 items and open-ended, essay type 5 itmes. The pilot test was to check the goodness of the test with 45 students. The practical test was implemented to 583 students. Goodness of the test items was evaluated by assessing content validity, internal consistency reliability, item difficulty. Content validity of the test is 87.9%, internal consistency reliability is .59, item diffidulty is .42. Concurrent validity of the test was evaluated by correlation analysis. The test were found to have correlation with the creative problem solving test(r=.75), the logical thinking test(GALT)(r=68), and scientific inquiry ability test(r=.62), the creativity test(GIFT)(r=.49). The creative problem solving test have the highest correlation with the test.

치과교정용 NiTi 합금계 선재의 탄성과 상변태 거동에 대한 열처리 효과

이진숙,김광만,김경남 대한치과기재학회 1997 대한치과재료학회지 Vol.24 No.1

Due to unique property of superelasticity, NiTi has been used widely since their introduction to the orthodontic specialty by Andreasen and Hillmann. But sufficent evaluation of superelasticity of domestic marketed wires has not yet been made. It has been known that heat treatment caused changes not only of elastic behavior but also of phase transformation behavior, an important factor of superelasticity. So, this study was investigated into varied ways of heat treatment of wires for orthodontic force proper for each clinical case. Each elastic behavior of 6 commercial NiTi alloy orthodontic arch wires(LG's ORTHOLLOY, G & H's Nickel Titanium arch wire, ORMCO's NI-TI and COPPER NI-TI, TOMY's SENTALLOY and 3M Unitek's Nitinol) were examined, and in order to study the effect of heat treatment on elasticity and phase transformation behavior, 3-point bending test, differential scanning calorimetry and X-ray diffraction with each wire heated at 350℃, 450℃ and 550℃ for 1hour were carried out compared with a as-recieved group. The results were as follows : 1. As a result of 3-point bending test in a control group, all wires had superelasticity and COPPER NI-TI showed the lowest maximum load as well as minimum(P<0.05). 2. As a result of 3-point bending est, except Nitinol and COPPER NI-TI, the wires in the group heated at 450℃ had lowest maximum and minimum load than that of a control group, and higher maximum and minimum load that of COPPER NI-TI in control group, and had superelasticity without and permanent deformation(P<0.05). 3. Phase transition temperature of all wires heated at 350℃ except COPPER NI-TI became higher but it became lower when they were heated at 450℃ and 550℃. 4. All wires in control group had austenite structure and when they were heated, martensite phase increased, and R phase appeared when heated at 550℃. The wires used in this study were changed in phase transition temperature, structure and elastic behavior as well by heat treatment. So this study showed that even the same kind of wire could be varied and used after heat treated, choosing proper load in accordance with each orthodontic clinic case.

석회침착을 동반한 위암 1례

김경숙,하해구 한양대학교 의과대학 1983 한양의대 학술지 Vol.3 No.1

The occurrence of calcification in gastric cancer is extremely rare. Since the first case report by Gruber in 1913, there are about 50 cases in the published literature. (The American Journal of Gastroenterology, 69:481, 1978) The purpose of this paper is to report an additional case of these rare entity with endoscopic observation. This 63 year old, male patient had nausea, vomiting and epigastric hard mass, that is a large apple size, for about 2 months duration. The simple abdomen of this patient showed mottled, stippled, granular, punctuate, sand like and miliary calcifying mass in the upper abdomen. And this was confirmed to mucinous adenocarcinoma of the stomach with upper G-I study, computed tomography, ultrasonography and endoscopic biopsy. The surgery was denied. The fine, sand-like calcifications found in gastric carcinomas appear to be characteristic of a mucus-secreting tumor. It is of interest that the findings permitting correct diagnosis were clearly indicated on a simple film of the abdomen. A few examples which were discorved on pathological examination, but without roentgenographic study, are not considered here.

오닐의 자서전적 측면에서 고찰한 『상복이 어울리는 엘렉트라』 : Christine and Orin 크리스틴과 오린을 중심으로

김경숙 신한영미어문학회 1999 새한영어영문학 Vol.41 No.-

The purpose of this paper is to demonstrate that Mourning Becomes Electra is one of Eugene O'Neill's autobiographical plays by showing that Christine and Orin of Mourning Becomes Electra are modeled on Ella O'Neill, O'Neill's mother, and O'Neill himself. It is true that Mourning Becomes Electra, regarded as O'Neill's Oresteia, has been excluded from O'Neill's autobiographical plays. Generally it has been considered only as a modern psychological drama in which O'Neill in interprets Aeschylus' Oresteia using a New England locale and placing the action during 1865-1866, just after the American Civil War. However, the physical and psychological resemblances between Christine and Ella and between Orin and O'Neill suggest that this play can be interpreted autobiographically. Christine and Ella have much in common in their physical appearances and in their relationships with their husbands and sons. They are both tall, striking-looking, graceful women. Both women have dark brown eyes with dark eyebrows, thick curly brown hair, and full, sensual lips. Further resemblances between Christine and Ella can be seen in their relationships with their husbands and sons. Both women fell in love with their husbands-to-be because of their dashing romantic presences. But the two women were disillusioned soon after marriage and coveted by their rebellious sons. Both women act to escape unhappy homes. Christine responds by taking a lover, and Ella responds by embracing her addiction. Both women commit suicide, though Ella fails. Christine's son, Orin resembles O'Neill physically and psychologically. Both of them are tall and thin, and have aquiline noses, dark complexions, black hair and sensitive mouths. Orin, like O'Neill, is moody and introverted. And, like the young O'Neill, Orin is the baby of the family, coddled by a doting mother. Both men are fascinated with the image of the sea. And they both write explicit stories about their families. Both of them have an Oedipus Complex in that they show a strong attraction to their mothers and an antipathy toward their fathers. Both men harbor subtle love-hate feelings toward their mothers, and these emotions develop into forgiveness and reconciliation with the passing of time. As in Long Day's Journey into Night, O'Neill makes an exit to free himself from his emotional obsession with his mother by experiencing the catharsis of forgiveness and reconciliation through projecting himself and his mother on the immense setting suggestive of Aeschylus' Oresteia.

최숙희,김성희,곽동경 대한영양사협회 2003 대한영양사협회 학술지 Vol.9 No.3

The purpose of this study was to identify obstacles by surveying dieticians' perception in implementing Generic HACCP Plan for school foodservice operations from 2001. The survey was conducted in five areas; Seoul, Kyoung-gi Province, In-cheon, Kwang-ju and Dae-jean. Five hundred and sixty questionnaire were sent by the e-mail address and the local school dietician's Community Board on the internet, 263 were returned. Two hundred and forty were returned by E-mail, return rate was 42.86%. Twenty three were received by the local school dietician's Community Board on the internet. The obstacles were grouped of six fields and indicated thirteen factors in implementation of the Generic HACCP Plan for school foodservice. The six fields were 'status of cooperation within HACCP team', 'cooperation with the external people' such as teachers, food suppliers, student's parents, 'understanding HACCP system of the dieticians', 'hygiene facilities', 'training & educating employees', and 'monitoring'. We used Likert's scale to assess the factor as a obstacle : 5-agree strongly, 4-agree, 3-medial, 2-don't agree, 1-dont't agree strongly. Results of this study are as follows; 1) The scores of thirteen factors indicated as obstacles were over 3(medial) except 'lack of dietician's understanding about HACCP System(2.86±0.97)'. Also only about 63% dieticians recognized that as an obstacle factor. 2) 'Deficiency of hygiene facilities(4.41±0.76)', 'lack of teachers' cooperation(4.23±0.77)', 'inadequacy of the kitchen lay-out(4.19±0.95)' and 'lack of training and educating program for employees(3.97±0.85)' scored most highly. Results from this study show that financial resources and educating system are very important to settle down HACCP system for School Foodservices successfully.

中學校 學生들의 멘델유전에 관한 誤槪念 硏究

이경숙,이길재,정완호 한국교원대학교 과학교육연구소 1994 청람과학교육연구논총 Vol.4 No.1

Misconceptions of scientific concepts have been believed to be very persistent and difficult to be overcome through regular classroom activities. Therefore, it is important to find the misconceptions and cognitive structure of students. Mendelian genetics is an important and difficult topic for the student to learn. It is also difficult for the teacher to teach. Chromosome theory of inheritance and the concept of gene is the most important and difficult topics relate to mitosis/meiosis. The purpose of this research is a study of middle school students' understanding of the physical relationship of chromosome and genes. Particularly, this study is to establish new teaching strategy of the 3rd grade middle school students, by analyzing misconceptions of genetic continuity and to enhance their problem solving performance. Total 100 students were selected for this study from 2 different classes. They were all females. The test taken by students was open ended questionnaires. It was developed by Moll & Allen(1987) and it was modified for this study. Misconception was analyzed by personal interview. Each of the interviews was recorded and transcribed. Everything that students wrote and drew during the interviews, as well as the interview transcripts, were used to construct the data to be analyzed. The new instruction program "chromosome card game" used to reverse the misconceptions of Mendelian genetics, which were discovered in this study. The new instruction program was reviewed by having controlled experiment and treated additional study group. The results of this study are as follows: 1. Students have misconception on sister chromatids, the pairs of homologous chromosomes and gamete types. 2. According to the conceptual knowledge of chromosome and gene behavior, three types of chromosome model were suggested such as one-chromosome model, two-chromosome model and four-chromosome model. Many students can not construct the conceptual knowledge of genetics and meiosis. There is a tendency toward being mathematical rather than genetic in problem solving. 3. After the new instruction program was applied to the students, much enhanced study effect was discovered among experiment group. Based on above mentioned study, the classroom teachers must recognize the misconceptions some students have, and modify students' misconceptions, and increase the probability of meaningful learning.
