Kim, Y . K .,Choi, S . H .,Jeong, J . W .,So, K . H .,Park, D . Y . 호남수학회 1999 호남수학학술지 Vol.21 No.1

Dimensions of irreducible so_5(F)-modules aver an algebraically closed field F of characteristic p$gt;2 shall be obtained. It turns out that they should be coincident with p^m, where 2m is the dimension of coadjoint orbits of χ∈so_5(F)%* \ 0 as Premet asserted. But there is no subregular point for g=sp_4(F)=so_5(F) over F.

The purpose of this study was to develop funtional lab gowns in the view of safety and work efficiency. As the first step of this study, we surveyed on satisfaction rates, preferences and inconvenience items in regard of lab gowns. The data was obtained from 138 graduate students specialized in science and 113 medical students. Respondents answered that the first purpose of wearing lab gown was to protect body from danger. Wearing frequency followed with 'always', 'as possible as', and then 'sometimes' Forty-five percentage of respondents answered that they didn't wear lab gowns often in summer because of hot weather. The contaminated or damaged parts of lab gowns followed with cuffs, abdomen, thigh, lower part, and then chest. Washing frequency followed with 'once a month', 'once per six months', and then 'more than once a week'. There were significant differences in normal wearing frequency, wearing frequency by season and washing frequency due to major. There were no significant difference by sex and major in all questions. In regard of the protective capacity of current lab gowns, most respondents answered that 'It's normal' (60%), ‘It's enough'(21%), so that they didn't show much dissatisfaction. Forty-three percentage of respondents were not satisfied with cuffs. Respondents answered that the cuffs were in danger and inconvenient because of broad cuffs. In regard of color, preference for white were high and followed with ivory, light sky, light green, and then light pink. Materials of current lab gowns were cotton/polyester or polyester 100%. Sixty-eight percentage of respondents were satisfied with that and others were not. The reasons for dissatisfactions were as follows; those materials were not protective to chemicals thoroughly enough. Cotton/polyester materials were heavy. Wearing sensation of polyester 100% was not good.

The purpose of this study was to evaluate thermal properties of lab gowns developed from the point of safety and work efficiency. We evaluated thermal and subjective responses of subjects wearing functional new lab gowns(Type B, C, D) and a popular lab gown on the market(Type A). Type B was a new lab gown made of woven fabric with functional cuffs. Type C was a new apron made of woven fabric with arm protectors. Type D was a new lab gown made of non-woven material with functional cuffs and openings around the armpits. Temperature in the climatic chamber was set at 19℃as an indoor temperature in winter and at 24℃ in summer. There were no significant differences in rectal temperature and heart rate among four types of gowns and between two air temperatures for 120min. Mean skin temperature was much higher in the type A and B than in the type C and D(p<.05). In the 19℃air, clothing microclimate temperature on the back was the highest in the type B and was the lowest in the type C (p<.05). Clothing microclimate humidity was not significant differences among gowns. In subjective responses, subjects perceived that Type B was the warmest gown in the 19℃ and the hottest and more humid in the 24℃ than other gowns. Inversely, type C was the coolest gown among four gowns. Both in the 19℃and in the 24℃, the Type D had gained most responses of being comfortable. In conclusion, the temperature difference of 5℃ was more of an influencing factor than the difference from four types of lab gowns. Secondly, we recommend the manufacturers to make lab gowns with functional cuffs for safety purposes. Thirdly, the spread of the type of apron with arm protector will contribute to increase of the frequency of wearing in summer. Fourthly, it is necessary to study continuously about lab gowns with non-woven materials for researchers exposed to toxic chemical and biological materials.

Rheology of Decamethylceclopentasiloxane (cyclomethicone) W/O Emulsion System

Choi, Min-Hyung,Jeong, So-Ra,Nam, Sang-In,Shim, Sang-Eun,Chang, Yoon-Ho The Polymer Society of Korea 2009 Macromolecular Research Vol.17 No.12

A highly dispersed W/O emulsion of silicone oil (cyclomethicone)/water system was prepared with a nonionic surfactant. The surface and interfacial tension between the oil and water were characterized in terms of the droplet size distribution and viscosity change of the emulsion. When the dispersed phase concentration was relatively high, the viscosity of the emulsion was rapidly increased and the droplet size of the emulsion was decreased. The rheological behavior of the emulsion system showed non-Newtonian and shear thinning phenomena depending upon the content of the dispersed phase. The droplet size of the emulsion was decreased with increasing surfactant content and water concentration. The relative viscosity of the emulsion was better predicted with the Choi-Schowalter model than with the Taylor model. The value of the complex modulus increased with increasing surfactant concentration. The linear viscoelastic region was expanded with a dispersed phase concentration. According to the change in the viscosity, the behavior was classified into three distinct regions: [I] linear viscoelastic, [II] partially viscoelastic, and [III] viscous. The creep/recovery behaviors in each region were characterized.

This study was performed to evaluate the effect of persimmon vinegar on serum lipid components in the hypercholesterolemic Sprague-Dawley male rats. Forty rats were divided into four groups and fed diets containing 1% cholesterol for 4 weeks. Experimental diets added to distilled water, 1.5%, 3%, and 7% persimmon vinegar(PV) as drinking water. Concentration of total cholesterol, LDL and HDL cholesterol, triglyceride in serum and activity of AST, ALT in serum were assayed. Average food intake, weight gain and FER of experimental rats were not significantly different by contents of persimmon vinegar. Concentration of total cholesterol and LDL cholesterol in serum were lowest in 7% persimmon vinegar group. However concentration of HDL cholesterol in serum was highest in 3% persimmon vinegar group. Concentration of triglyceride in serum was significantly lower in persimmon vinegar group than control group. Activities of AST and ALT in serum were lowest in 7% persimmon vinegar group. The results in this study suggest that persimmon vinegar is effective in lowering serum triglyceride level.

어린이의 치과치료시 약물에 의한 진정요법 사용에 대한 실태조사

안소연,최병재,곽지윤,강정완,이제호 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.3

진정요법은 소아치과에서 사용하는 보상, 속박, 체계적 탈감작법(말-시범-시행), 친밀감 같은 통상의 방법으로는 환자의 반응이 개선되지 않아 일반적인 치과치료가 불가능할 때 사용하는 행동조절법이다. 최근 국내에서도 진정요법을 이용하는 사례가 증가하는 추세이나 그 기준이나 방법들에 대한 연구는 매우 부족한 상태이다. 미국소아치과학회의 진정요법에 관한 기준이 있기는 하지만 국내의 상황이 미국과 다르므로 한국에서의 연구가 필요하다. 이에 저자는 국내에 거주하고 있는 소아치과의사들을 대상으로 국내 소아치과에서의 진정요법 현황에 대한 실태를 조사, 그 결과를 정리하여 향후 소아치과 임상에서의 진정요법에 대한 임상 기준을 정하는데 기여하고자 국내에 거주하고 있는 대한소아치과학회 회원 573명을 대상으로 진정요법 사용 실태에 관한 설문지를 발송하여 이 중 회신을 한 220명의 설문을 분석하여 다음의 결과를 얻었다. 1. 응답자의 약 66%가 진정요법을 사용하고 있다고 답했다. 진정요법에 관한 이전 연구 결과와 비교해 볼 때, 국내 소아치과에서 진정요법의 사용빈도가 증가하였다. 2. 진정요법으로 치료를 결정 하게 된 요인은 행동조절, 치료내용과 양, 보호자의 요구, 내원횟수, 전신질환의 순서이었다. 3. 진정요법으로 치료받는 환자의 연령은 만 3세가 가장 많았고, 만 4-5세, 만 2세 미만, 만 6-10세, 만 10세 이상의 순서로 조사되었다. 4. 진정요법 시 chloral hydrate는 60-70mg/kg, hydroxyzine은 10-40mg/kg(25mg/kg)을 사용하고 있었고, 경구 투여가 가장 선호하는 약물투여 경로였다. 5. 진정요법 시 사용하는 환자감시 방법은 피부나 손톱색 둥의 관찰을 포함한 환자 평가와 맥박 산소측정기(pulse oximeter)를 통한 환자감시를 선호하는 것으로 조사되었다. 6. 진정요법을 사용하고 있다고 응답한 사람의 약 56%에서 심폐소생술 교육을 받은 것으로 조사되었다. Sometimes the dentists encounter a child who can not be treated with traditional behavior management techniques (for example, reward, restraint, Tell-Show-Do, familialization). In such a case, the dentists use sedation technique. Recently, in Korea, the use of sedation by pediatric dentists is increased. But, the guideline and survey of sedation is very insufficient. Now, we need a survey of sedation practice in Korea. We carried out research on the actual condition about sedation with a questionaire to pediatric dentists in Korea. Followings are the conclusions 1. Sixty six percent of pediatric dentists use sedative agents in their practice. In this study, using sedation shows an increase as compared with the past. 2. Determinative factors of using sedation were orderly behavior management, number of visiting, guidian's opinion, amount of treatment, general condition. 3. Distribution of ages in patients sedated with agents was orderly 3 years, 4-5 years, under 2 years, 6-10 years, more than 10 years. 4. Particular sedative drugs were chloral hydrate 60-70mg/kg, hydroxyzine 10-40mg/kg(25mg/kg), and oral route was the most favorable route. 5. Observation of skin and nail color, pulse oximeter were the most frequently utillized monitoring method during sedation. 6. Only fifty six percent of pediatric dentists complete the cardiopulmonary resuscitation course.

오감(五感)적 요소를 접목한 브랜드 스페이스 연출 계획 -마임 화장품 프레쉬가든을 중심으로-
