The palmoplantar keratoses comprise a heterogenous group of disorders of keratinization, which can be subdivided into hereditary and acquired forms. Epidermolytic palmoplantar keratoderma (EPPK) is an autosomal dominant disease which presents as abnormal thickening of the palms and soles with epidermolytic hyperkeratosis pathologically. We report a 18-month-old female baby showing the clinical and histologic features of EPPK without family history. She has been treated intermittently with topical urea and oral isotretinoin for 2 years, but the lesions remain unchanged.

본 연구자들은 취장의 초음파적 영상을 좀 더 잘 묘출 하기 위해서 여러 촬영법 보다 나은 영상을 얻을 수 있는 새로운 촬영법을 고찰 하였다. 취장의 영상 묘출 기술은 올바른 자세잡이와 위장과 소장 내에 있는 공기의 제거 위장속에 물을 넣어서 초음파 검사시 acoustic window로 삼는 것이다. 그래서 본 연구자 들은 취장 영상에서 보편적 방법과 고찰한 새로운 방법으로 촬영한 사진을 상호 비교 분석 하였다. 총 10 명의 취장 검사 환자를 대상으로 조사한 결과 입위 20˚위장 내 물 삽입법이 다른 기존 촬영법 보다 나은 취장의 영상을 얻을 수 있었으며 보통 앙와위자세에서 촬영 할 경우 잘 나타나지 않는 취장의 취미 부분이 새로운 촬영법에서는 향상된 영상이 묘출 되었다. The examination of abdominal organs such as stomach, pancreas, liver and kidney have been made by radiologic studies using contrast media and radio-isotope scan before, but today the utilization of computed tomography and ultrasound is increasing. The computed tomography is not availabla for the examination of infants in growing periods or pregnant women, for there are lots of radiation hazard to the patient. Despite its merits of harmlessness, ultrasound has many limitations in observing some abdominal organs below the gas-filled stomach and intestine, because ultrasound cannot penetrate air and bone on account of its physical characteristics. Livers and gallbladders can be observed with ultra sound with relative success, but highly sophisticated skills are required to demonstrate pancreas which is located between the stomach and the duodenum. Authors scanned experimental ultrasonic examination. Sonic images obtained in each position after ingestion of water were compared with the general technique. The semi-erect(200) ingestion water gastro window technique showed further improvement in 10 patients of pancreatic study examization. Using general technique, non visualization of the tail of pancreas occured. In contrast, with semi-erect(200) gastro window technique produced improved visualization.

안세원,박경권 慶星大學校 1999 論文集 Vol.20 No.2

In today, because of competitive marketplace, varying degrees of consumers needs, many products have characteristic of varying and complexity. Many product share common features, cash services are a common feature for credit cards, free guarantee periods are a common feature for new cars, modems and CD-ROM are a common feature for most computers. These common feature viewed as very attractive by some consumers may be perceived as less attractive or even as unattractive by others. Hence the common features affect the consumer brand choice and consumer preference. This dissertation examined two testing condition. First, when consumers have a strong ordinal preference and in a absence of established ordinal for a given attribute, how adding common features to two brands in a given product category affects consumer preference and brand choice. Second, in the presence of primary attribute a given attribute, how adding attractive/unattractive common features in a given product category affects consumer preference and brand choice. Research findings presented in this dissertation are common features to two brands in a given product category may have a significant impact on the choice and adding either attractive or unattractive common features can have a significant impact on consumers' brand preferences. The result of this study may have meaning of the understanding of the constructive nature of consumer preference and provide new insights on the role of attribute importance and information diagnosticity in brand choice. For marketing practitioners, this research offers a new approach to brand differentiation, showing how firms can take advantage of product features to achieve the desired strategic positioning in the marketplace.

Chitosan derivative was used to improve the solubility of chitosan in water. The deacetylation degree of the chitosan was 98.7%. The viscosity-average molecular weight of EuCs-1, EuCs-2, and EuCs-3 were 13.Ox10^(7), 9.53×10_(6), and 4.92×10_^(6). The molecular structures of Cs and EuCs were confirmed using FT-lR and ^(1)H-NMR. The effects on bacterial growth inhibition were investigated using the WCs and EuCs as antibacterial agents and foot care (Candida of albicans), mouth (Streptococcus mutans), and skin(Propionibacterium αcnes) as microbials. Inhibition ratio of water-soluble chitosan in Candida albicans was 63% in the input of 3ml and those of streptococcus mutans and Propionibacterium acnes were 48% and 53% in the input of 2ml, respectively. Results from inhibition ratio of chitosan-derivatives, EuCS reveal that optimal volumes in Candida albicans were 1ml, 2ml, and 3ml in EuCs-1, EuCs-2 and EuCs-3, respectively. Optical volume for inhibition of Propionibacterium acnes was 1ml in all chitosan-derivatives. From the results. antibacterial activity was increased with viscosity-average molecular weight of EuCs, however, showed the various results from the kinds of bacterial.

김원경,박정희 韓國學校保健學會 2001 韓國學校保健學會誌 Vol.14 No.2

This study was carried out to identify the effects of an art therapy program based on reality therapy on the weight control, body image, and self-esteem of college students. The program was developed by the authors. The design was a pretest-post test control group design. The subjects were college students attending M college : 8 in experimental group A, 6 in experimental group 2, who wanted to control their body weight and 16 in the control group who didn't attend the program. those in the experimental group attended the program once (group A) or twice (group B) per week meeting a total of six times. The data were analyzed by quantity method (SPSS 10.0 program) and quality method(process analysis). The results were as follows ' 1. The average obesity index of pre-test, post-test, and a follow-up test decreased from 8.9% to 6.1%, 3.7%. And the rate of decrease broth pre-post and post-follow up were statistically significant. 2. The average obesity index of group A decreased from 9.6% to 6.3%, 4.1% and the rate of decrease between pre and post were statistically significant. But the rate of decrease between post and follow-up were statistically not significant. 3. The average obesity index of group B decreased from 7.8% to 5.8%, 3.1% and the rate of decrease between pre and post were not significant statistically. But the rate of decrease between post and follow-up were statistically significant. 4. The average scores of pre and post body image increased and were statistically significant : group A from 129.0 to 153.5, group B from 127.7 to 156.2. 5. The average scores of pre and post semantic differential method increased and were statistically significant : group A from 38.1 to 44.1, group B from 38.0 to 45.0. 6. The average scores of pre and post self-esteem increased : group A increased from 37.3 to 40,3 and were statistically significant, group B increased from 36.5 to 39.5 but was statistically insignificant. 7. The average scores of pre and post obesity rate, body image, semantic differential method and self-esteem in the control group were not statistically significant. 8. The pre and post scores of body image(p=.001), semantic differential method(p=.001) and self-esteem(p= .039) between experimental and control group were statistically significant. 9. In Duncan multiple comparison, it was not statistically significant between group A and B, but statistically significant between group A and the control group, group B and the control group in obesity index, body image, semantic differential method. There was no statistically significance among the three groups in self esteem. 10. In Duncan multiple comparison, group A gained tougher scores than group B in obesity index(-1. 2%), and self esteem(0. 3). Group B gained higher scores than group A in body image(3. 0), and semantic differential method(1. 0). So it is difficult to conclude whether group A or B is more effective. In conclusion, the art therapy program based on reality therapy was effective in weight the control program of college students: obesity was decreased, the scores of body image and semantic differential method and self-esteem were increased. The scores of group A were increased more than group B and were statistically significant, The time interval was a very important factor in this program. The recommendation is : the validity of this program has to be tested through various subjects and in various areas. And also tutus program has to be tested in other topics.
