Purpose: This study was aimed to investigate the effects of gum-chewing on the recovery of bowel movement and oral cavity discomfort after abdominal surgery. Method: The nonequivalent control group, non-syncronized repeated treatment design was used. A total of 99 patients were participated in the study. The 44 patients were in the experimental group and the rest in the control group. The experimental group chewed gum three times a day until they passed gas. As the patient reported gas-passing, bowel movement time, subjective symptoms of oral cavity, and oral status were recorded precisely. The frequency, percentage, ???u -test and t-test were analyzed by SPSS PC 12.0. Results: There were significant differences in bowel movement, gas passing, oral cavity symptoms, and oral status scores between the experimental and the control group. Conclusion: The findings of the study demonstrated the fact that gum-chewing helps early recovery from post-operative ileus and thirst. It is because gum chewing stimulates bowel mobility and secretion of saliva. Thus gum-chewing seems to be an effective nursing intervention in reducing post-operative side effects for patients with abdominal surgery.

The Discourse of Madness in Plath`s and Gilman`s Pathology

( Gum Hee Che ) 한국현대영어영문학회 2013 현대영어영문학 Vol.57 No.1

Che, Gum-Hee. “The Discourse of Madness in Plath`s and Gilman`s Pathology”. Modern Studies in English Language & Literature 57.1 (2013): 311-26. Highlighting the lack of communication between a male doctor (the observer) and a female patient (the observed), Plath and Gilman subvert the role of the observer (the master of madness), who fills himself with doctrines and myths of reason, and discredit his clinical diagnosis and treatment, believing that pathology as such cannot explain the unconscious of her psyche. Escaping the symmetrical polar opposition between the doctor and the patient, they reveal that the objectivity of the unconscious is an illusion and her psyche may not be approached by reason and observation. The discourse of madness in Plath and Gilman`s pathology presents a very thin layer between sanity and madness, which may open the door to a wider outlook on the relation between the human psyche and the unconscious. As there is no distinct line between sanity and madness, it would not be easy for one to find any definite borderline between the doctor and the patient. (Chungbuk National University)

Flutter and buffeting responses of the Shantou Bay Bridge

Gu, M.,Chen, W.,Zhu, L.D.,Song, J.Z.,Xiang, H.F. Techno-Press 2001 Wind and Structures, An International Journal (WAS Vol.4 No.6

Shantou Bay Bridge is the first long-span suspension bridge in China. Because of its location near the Shantou Seaport and its exposure to high typhoon winds, wind-resistant studies are necessary to be made. In this paper, critical flutter wind speeds and buffeting responses of this bridge at its operation and main construction stages are investigated. The Buffeting Response Spectrum method is first briefly presented. Then the sectional model test is carried out to directly obtain the critical flutter wind speed and to identify the flutter derivatives, which are adopted for the later analysis of the buffeting responses using the Buffeting Response Spectrum method. Finally the aeroelastic full bridge model is tested to further investigate the dynamic effects of the bridge. The results from the tests and the computations indicate that the flutter and buffeting behaviors of the Shantou Bay Bridge are satisfied.

시클로부탄고리를 가진 감광성 poly(amide-imide)의 합성 및 특성

선금주 광주보건대학 2004 論文集 Vol.29 No.-

Photosensitive poly(amide-imide)s (PAIs) containing cyclobutane group were synthesized and studied for the properties of positive type photoresist. PAIs were prepared by direct polycondensation of N-(4-caboxyphenyl)maleimide cyclobutane dimer(p-MCD), N-(3-carboxyphenyl)maleimide cyclobutane dimer(m-MCD) and diamine with triphenylphosphite(TPP) and pyridine as a polymerization catalyst. The PAIs were insoluble in gerneral organic solvents, but fairly soluble in polar aprotic solvents such as NMP, DMSO, DMAc, DMF. Intrinsic viscosity of PAIs measured in NHP was 0.39 g/dL, 0.26g/dL. The onset of themal decomposition temperature was 426℃ which shows relatively high thermal stability. The PAIs were insoluble in THF before irradiation. However, they became soluble upon irradiation with 254㎚ UV light. This result shows that PAIs have the properties of positive type photoresists. Differnce FT-IR spectral study showed the photooxidation of amide and imide groups as well as photosplitting of cyclobutane rings took place during the photolysis of PAIs.

Economic development and advanced medical science have lengthened life expectancy. Industrialism caused migration, prevalence of nuclear family and isolation of the aged. The aim of this study is to help older people not only to survive but to live an enhanced life within their communities. In this process are involved many “actors” such as politicians, manners, opinion-makers, various professionals among them also nurses,―and last, but not least―the consumers of these resorces,― i.e., the elderly themselves : commercial-profit bodies, and first and foremast―the governments. Individual behavior and life style are seen as the dominant and presumably modifiable source of the unfortunate outcomes for health and well being. And sensing and perceiving play a crucial role in behavior. So individuals are exhorted to change their undesired ways of life and professionals are exhorted to help individuals do so by raising the extent of health perception.

The Error Backpropagation Alogorithm has great populatity for its simplicity and algorithmic stability, but its generalization property, i.e.correctness ratio, is not satisfactory. In this paper, we proposed post processing techniques which significantly enhance the correctness ratio. We have shown that, when arbitrary input patterns are given to neural networks, our proposed methods improve the probability of getting correct answers, and reduce the chances of spurious answers, over the conventional Error Backpropagation Algorithm.

Fish fauna was investigated at six stations in Kum-river estuary during the periods from Feb. to Dec., 1990, twice a month. In order to reveal the environmental influences on fish fauna, water temperature and salinity were measured in each station. The results are as follows: 1. Water temperature was the highest with 31 C in Aug. (all stations) and the lowest with 2 C in Feb. (St. 4, 5, 6). Salinity was the highest with 16.45%0 at St. 6 in Feb. and the lowest with 0.06%0 at St. 1 in July. 2.

The purpose of this experiment was to determine the effects of etching with a Nd : YAG Laser on dentin, or porcelain surface on the bond strength with composite resin. The dentin specimens were devided into the following 4 groups. D1 : No treatment D2 : Etched with 10% phosphoric acid D3 : Laser etchded with 1W, 20PPS D4 : Laser etched with 2W, 20PPS The procelain specimens were devided into the following 4 groups. P1 : diamond roughened P2 : etched with HF acid P3 : Laser etched with 2W. 20PPS P4 : Laser etched with 3W, 20PPS All specimens were veneered with resin. One half of the specimens were stored in 37℃ water for one day and the other half were thermocycled 1000 times at temperature of 5℃ to 55℃ at 20 seconds intervals. After that, the bonding strength of composite resin to the dentin and porcelain was measured. The surface treated state and fractured state were observed with SEM. The following results were obtained. 1. In the dentin specimens, the bond strength of group D2 was higher than that of groups D1 and D3 in the case of the specimens stored in 37℃ water for one day, there was a statistically significant difference between group D2 and D1, D3(P<0.05). The bonding strength of the specimens that were thermocycled decreased in the following order : group D2, D4, D3 and then D1. 2. In the porcelain specimens, the bonding strength of groups P1, P2 were higher than that of group P3 in the case of the specimens stored in 37℃ water for one day(P<0.05). The bonding strength of the specimens of being thermocycled decreased in the following order : group P2,P1,P4 and then P3. 3. The groups of high bond strength had a rougher surface and a high level of microporosity with SEM findings.
