실내 환경내에서 관엽식물의 보다 효과적인 이용과 시각, 심리환경 스트레스 경감을 목적으로 관엽식물의 형태적 특성이 인간의 정신생리와 심리에 미치는 영향을 알아보고자 잎모양이 다른 아로우카리아(Araucaria excelsa)와 벤자민고무나무(Ficus benjamina), 잎크기가 다른 네프로네피스(Nephrolephis exaltata)와 스킨답서스(Scindapsus aureas), 그리고 수형이 다른 관음죽(Rhapis humilis)과 아레카야자(Chrysalidocarpus lutescens)를 선정하여 각 식물당 남녀 24명 총 72명을 대상으로 뇌파(Computerized EEG)검사, 혈압, 맥박, 시각이미지 평가를 시행하였다. 각 식물에 따른 뇌파를 비교한 결과 뚜렷한 차이를 보이지 않아 관엽식물의 관상에서 잎의 모양, 크기 및 수형이 있는 상태에서 모두 유의한 감소를 보여 스트레스 감소 효과와 안정 효과를 보인 것으로 나타났다. 그러나 각 식물간에는 유의한 차이는 없었다. 이러한 사실은 기존 연구에서 보여준 결과인 식물의 녹색에 대한 정신생리적 반응과 녹(綠)면적에 의한 뇌파변화는 인정되었지만 식물종류에 따른 반응은 중요하게 작용하지 않는 것으로 보여진다. 관엽식물에 대한 이미지는 평가는 4개의 요인 심미성, 청량감, 안정성, 질감성 인자로 구성되었다. 각 인자에 대한 식물종류간에 차이를 조사한 결과 서로 다른 특성을 보였으나 4인자인 질감성 차원에서는 차이가 없었다 이는 의식적으로 인식되는 시각적 이미지 평가요소에서 제 1인자인 심미성과 제 2인자인 청량성이 더 중요하게 작용되는 것으로 판단되었다. 앞으로 보다 명확한 효과를 검정하기 위해 녹시율(綠視率)과 여러 식물 종류를 조합한 좀 더 세밀한 비교와 함께 시간흐름에 따른 뇌파비교를 동시에 조사 분석하는 것이 필요한 것으로 판단된다.

The chole lithiasis of the biliary system is one of the most common diseases which are hospitalized and treated surgically in the field of general surgery. A retrospective study of 175 patients who admitted and treated surgically with chole lithiasis at the department of general surgery of Chung-nam National University Hospital from March 1987 to September 1989 was performed. The results are as follow: 1. The peak incidence of chole lithiasis was 6th decade, 32.0% and followed by 7th decade, 20.0% and 5th decade, 17.7%, and the ratio of females and males is approximately 5:4. 2. The stones are most farequently found in the gall bladder 62.3%, and followed by in the common bile duct 56.6%, and in the intrahepatic duct 24.2%. 3. The most common symptoms and signs are pain, 96.6%, tenderness, 67.4%, and fever and chill 66.9%, and over 60% of patients were suffered from less than 3 months. 4. The results of culture shows the E.coli was found in 37.0% and klebsiella 12.3% of patients. 5. The laboratory finding reveals that moderated elevation of SGOT, SGPT, and alkaline phosphatase in about 40%, and 50% of patients. 6. The major operative procedures are cholecystectomy, choledochotomy and T-tube drainage in 49.1% of patients and cholecystectomy only in 32.9% of patients. 7. The major associated diseases are cholecystitis in 37.1%, cholangitis in 15.0% and gall bladder empyema in 12.0%. 8. The most common complication is wound infection n 12.0% of patients and followed by residual stone in 9.0% of patients. 9. The overall mortality rate is 1.2% and the causes of death are one case of sepsis and one case of bile peritonitis.

The PAN-Cu (Ⅱ) and Al(Ⅲ) complexes were most stable in the pH range from 9 to 11. The viscosity of the PAN-Cu (Ⅱ) complex was lower than that of PAN-Al(Ⅲ)complex because the conformation of the former is more compact than that of latter. The catalytic activity of PAN-Cu (Ⅱ) complex in decomposition of hydrogen peroxide was increased with an increase of complex concentration and reaction time. The PAN-Cu (Ⅱ) complex exhibited electrical resistivity around 10⁴Ω·cm when modified iodine in acetone. The electrical resistivity was significantly affected by the amount of added cupric chloride, iodine and results were satisfactorily obtained by adding more than 20wt % of cupric chloride and about 1.0wt% iodine.

원예치료가 만성정신분열증 환자의 자아존중감 및 사회성 향상에 미치는 영향

손기철,엄수진,김수연,송종은,백기엽 충북대학교 첨단원예기술개발연구센터 2000 연구보고서 Vol.5 No.-

만성정신분열증 환자들은 장기간의 치료를 필요로 하고, 지금까지는 대부분의 환자들이 약물치료나 전통적인 정신치료에만 의존해왔다. 최근에는 정신분열증 환자치료에 있어서 여러 가지 사회 재활 프로그램이 도입되고 있는 실정이나 원예치료프로그램의 적용사례는 미비한 실정이다. 이에 본 연구는 원예치료가 만성정신분열증 환자의 자아존중감 및 사회성 향상에 미치는 효과를 알아보기 위하여 음성 꽃동네 정신분열증 환자 남녀 대조군 20명, 치료군 남녀 25명을 선정하여 실험을 실시하였다. 대조군 20명에게는 원예치료를 실시하지 않았으나, 치료군 25명에게는 주 2회씩 2000년 4월 13일부터 9월 7일까지 원예치료를 실시하였다. 치료효과 검증을 위해 원예활동 평가표(evaluation of horticultural activity), 사회행동척도(social behavior scale), 자아존중감척도(self-esteem Scale), 인간관계측정지, 간이정신건강진단지(SCL-90-R) 등을 치료 전후로 시행하여 비교하였다. 자아존중감과 인간관계측정지에서는 대조군에서는 유의한 결과가 보이지 않은 반면, 치료군에서는 향상된 결과를 볼 수 있었다. 사회행동척도에서는 언어적인면보다 비언어적인면, 대화의 내용에서 치료군만 유의하게 향상된 결과를 보였다. 간이정신건강진단지 평가는 불안, 우울, 대인예민성 부분에서 역시 치료군만 유의하게 호전된 효과를 볼 수 있었다. 또한 신체화, 강박증, 적대감, 공포불안, 편집증 등이 호전된 것으로 보여졌으나 통계적으로 유의한 차이는 나타나지 않았다. 원예활동평가에서는 참여성과 자아개념 및 주체성에서 유의한 차이를 볼 수 있었다. 따라서 원예치료프로그램은 우울ㆍ폐쇄적인 대인관계를 보이는 정신분열증 환자들에게 심리ㆍ정서면과 사회성 향상에 효과적이라 판단된다. 또한 원예치료프로그램을 치료적인 목적뿐만 아니라 직업재활의 한 방면으로 이용가능 할 것이라 판단된다.

PPG와 MDI를 이용한 Polyurethane Ionomer의 합성과 전기전도성에 관한 연구

맹기석,송해영,김동철,백중현 忠南大學校 産業技術硏究所 1988 산업기술연구논문집 Vol.3 No.1

Hydroxyl-terminated polyether polyurethanes based on 4,4′-diphenyldiisocyanate(MDI), N-methyldiethanolamine(MDEA) and polypropylene glycol-2,000(PPG) were synthesized with constant level of hard segment. The tertiaryamine of MDEA was sulfonated with r-propane sultone thereby converting the polyether polyurethane to a polymeric Zwitterion. Electrically conducting polyurethane ionomer film was prepared by introducing copper sulfate. The CuxS-induced electrical conducting of polyurethane ionomer film was higher by order 10⁴ than that of the original film. The morphology of CuxS-induced PU, PUI film surface was investigated with SEM.

The oral bioavailability of itraconazole is variable and low in fasting state. This is mainly due to the low solubility of this drug. Bioavailability can be improved by changing the formulation and it is general that the liquid preparations show greater bioavailability than the solid dosage forms such as tablets and capsules do. Benzyl alcohol-water binary mixture showed the excellent solubilizing capacity for itraconazole but the release of the drug from the preparation needs to be enhanced. In this study, various nonionic surfactants and hydrophilic polymers, poloxamers, were screened to investigate their effects on the release of itraconazole from the liquid preparations. Poloxamer 407 showed the most enhancing effect on the drug release and the release rate was proportional to the amount of poloxamer 407 added. A liquid preparation of itraconazole, consisting of benzyl alcohol/water/poloxamer 407 ternary solvent system, released more than 80% of the total drug amount at 5 min and showed the possibility of a new formulation development.

This study was to investigate the effect of horticulture therapy on the healing and rehabilitation of the mentally retarded (MR) and physical disorder (PD) persons. Horticultural therapy program was carried at S rehabilitation center located in Kyounggi-DO from Jun 29, 1999 to Oct 12, 1999. The participants in this program were 36 clients of MR and PD. They attended 14 times once a week for 1 hour at a time for horticultural therapy. Evaluation of horticultural activities and ADL (Activities of daily living) has been assessed two times, that is, before and after horticultural therapy program (HTP) whereas horticultural therapy group activity treatment procedure and horticulture task skill inventory have been assessed 3 times, that is, before HTP and after each 7 weeks. MR in the evaluation of horticultural activities showed statistically significant in participation, interest and assistance, verbal interaction during activity, self-concept and identity, need-drive adaptation, interpersonal and social relations, cognition and problem solving, exercise perceptivity, life-tasks skill and vocational adjustment. In activities group of MR also showed significant improvement in terms of physical perceptual abilities, cognitive ability, writing ability, social interaction (P<0.001). Additionally, their horticulture task skill were improved significantly in skill and efficiency factor (P<0.008) and their ADL were changed positively but not significant. On the other hand, PD in evaluation of horticultural activities showed significantly positive changes in self-concept and identity, interpersonal and social relations, life-tasks skill and vocational adjustment. However, physical perceptual abilities factor was proven to be effective in horticultural therapy group activities treatment procedure (P<0.002). Only grooming was significantly improved in ADL evaluation of PD (P<0.03). Putting these results together, it was found that horticultural therapy programs would be very useful for rehabilitation and healing method in both MR and PD.

The Actinomyces species are normal flora of oral cavity and upper intestine characterized as gram-positive, non-spore-forming anaerobic or mjcroaerophilic rods. Actinomycosis is a chronic suppurative and granulomatous disease characterized by abscess, sinus, abundant granulation and mass. The appendix is the commonly involved site among abdominal actinomycosis. Abdominal actinomycosis is often difficult to diagnose before operation because of no reliable clinical features and infrequency of the disease. We report two cases of abdominal actinomycosis which were manifested as acute appendicitis. Those were detected Incidentally tv the pathologist after routine appendectomy. Both patients were successfully treated with appendectomy followed by proper antibiotics use.
