김조천,홍지형,주명칠,전진,김기준 동신대학교 환경연구소 2002 환경연구 Vol.7 No.1

소나무로부터 직접 배출되는 주요한 모노테르펜 물질로 α-pinene, camphene, myrcene, β -pinene, α-phellandrene, α-terpinene, d-limonene, p-cymene, β-phellandrene 등이 확인되었다. 7년생 소나무에서 직접 배출되는 모노테르펜 물질의 구성비를 분석한 결과 β-pinene이 67.0%로 가장 높았고, 22년생 소나무 경우에 β-phellanone이 37.4%로 가장 높았으며, 32년생 소나무는 α-pinene 구성비가 약 42.9%로 가장 높았다. 소나무는 수령에 따라서 구성비에 큰 차이를 보였으며, 소나무 수령이 높을수록 α-pinene이 구성비가 높았다. 소나무의 수령별 α-pinene과 β-pinene의 비율(α-pinene/β-pinene)을 비교한 결과, 7년생 소나무의 경우 0.16~l.15 범위로 나타났고, 22년생 소나무의 경우 0.64~2.47로 나타났으며, 32년생 소나무의 경우 0.50~18.47 범위로 나타났다. α-pinene과 β-pinene의 비는 수령이 높아질수록 좀 더 높은 값을 보였고, 동일한 수령일지라도 나무에 따라서 차이를 보였다. The major monoterpenes emitted from the Pinus densiflora were α-pinene, camphene, myrcene, β-pinene, α-phellandrene, α-terpinene, d-limonene, p-cymene and β-phellandrene. As a result of comparison of monoterpene composition by tree age for P. densiflora, it was found that β-pinene was a dominant monoterpene for 7-year-old pine(67%). β-Phellandrene(37.4%) and α-pinene(46.1%) were most abound for 22-year-old pine and 32-year-old pine respectively. The ratio of monoterpene composition varied considerably with tree age for the pine, and the percentage of α-pinene composition increased with tree age. The ratio of α-pinene and β-pinene(α-pinene/β-pinene) increased with tree age, and varied tree to tree.

고분자 습도센서의 감습재료로 이용하고자 4-vinylpyridine (4-VP) 과 methylmethacrylate(MMA) 의 공중함체를 전극에 도포한 후 α, ω-dihaloalkane으로 4 차 암모늄화시킨 후 습도변화에 따른 전기저항을 측정한 결과 소수성 모노머인 MMA의 양이증가할 수록 전기저항이 증가하였으며, 또한 α, ω-dihaloalkane에 의한 4차 암모늄화 반응시간에 따라서도 전기저항의 크기 및 감습막의 안정성에 차이가 있음을 알 수 있었다. In order to for a humidity sensitive material of polymeric humidity sensor, a copolymer of 4-vinylpyridine (4-VP) and methylmethacrylate (IBA) is coated on the electrode and then 4 quartermization by α, ω-dihaloalkane, and thereafter measured the electrical resistance due to humidity variation. As a result, the more content of MMA which is a hydrophobic monomer is increased, the more property of electrical resistance is increased. Also, according to the reaction time in 4 quarternization by α, ω-dihaloalkane we can see the diferences of the magnitude of electrical resistance and the stability of humidity -sensitive membrane.

To investigate the role of adjuvant for cytotoxic T lymphocytes (CTL) induction, squalene-based adjuvant was studied its capability eliciting to the induction of cellular immunity as well as humoral immunity to exogeneous proteins. Ovalbumin (OVA) was used as model proteins. It was demonstrated that antigen formulation consisted of metabolizable oil squalene mixed with Tween 80 and pluronic L121 (S/TJ121) could induced the antigen specific CTL responses and antibodies irrespective of immunization routes in mice. We also demonstrated that this antigen formulation was a inducer of CD8+, major histocompatibility complex(MHC) class I-restricted, and antigen-specific C;1'Ls. These data suggest that the squalene-based emulsion system is a potent adjuvant inducing cellular immunity as well as humoral immunity.

The use of a tissue expander and implant is the simplest option for breast reconstruction after mastectomy. Use of a round dome-shaped prosthesis and the commonly used one-stage technique with a Becker type prosthesis, however, often produces an undesirable upper pole fullness. To overcome this and to achieve improved aesthetic results, we started using an anatomically-shaped expander and implant, as described by Maxwell, as a two-stage breast reconstruction. We reviewed the results of our 21 reconstructed breasts in 22 patients who were deemed suitable for reconstruction using this technique since January 1995. The most commonly used expander was 350cc (range 350-550cc) and an average of 4.2 inflations were required before replacing the expander with a permanent implant. All the expanders were placed in submuscular pockets and implant volume. The longest follow-up was 36 months. Few complications developed and most patients were satisfied with the results. We found that the anatomically-shaped expander and implant produced better aesthetic results compared to a done-shaped prosthesis.

연구목적 : 정신분열별 환자들을 대상으로 통합심리치료의 소프로그램인 인지분화훈련을 실시하여 실행기능, 개념형성능력, 언어능력 및 추론력에 대한 훈련이 보다 더 하위단계의 인지기능인 주의력, 기억력, 반응시간 등을 호전시킬 수 있는 지를 알아보고자 하였다. 연구방법 : DSM-IV상 정신분열병으로 진단된 24명의 입원환자를 무작위로 양분하여 한 군은 인지분화훈련군으로 다른 한 군은 대조군으로 나누었다. 훈련군은 4주동안 1주일에 3회(매회 60분간)로 총 12회의 통합심리치료의 인지분화훈련을 받았으며 대조군은 동일한 시간동안 정신건강교육을 받았다. 훈련전후에 훈련군과 대조군을 대상으로 개정판 Wechsler 기억검사로 주의집중력, 장·단기 기억력을 측정하였고 Vienna test system중 결정반응시간검사로 반응시간, 반응결정시간, 반응운동시간을 평가하였다. 연구결과 : 1) 주의집중력에서는 훈련군과 대조군사이에 집단간 효과, 집단내 효과 및 상호작용 효과가 없었다. 2) 단기기억력에서는 훈련군과 대조군사이에 집단내 효과는 있었으나(F(1,24)=10.46. p〈.05). 집단간 효과, 상호작용 효과는 없었다. 3) 장기기억력에서는 훈련군과 대조군사이에 집단내 효과는 있었으나(F(1,24)=15.09. p〈.05). 집단간 효과, 상호작용 효과는 없었다. 4) 반응시간에서는 상호작용 효과(F(1,24)=5.18, p〈.05)가 있었다. 5) 반응운동시간에서는 집단간 효과, 집단내 효과 및 상호작용 효과가 없었다. 6) 반응결정시간에서는 상호작용 효과(F(1.24)=6.00, p〈.05)가 있었다. 결 론 : 통합심리치료의 인지분화훈련은 정신분열병 환자에서 하위단계의 인지기능 중 반응시간(특히 반응결정시간)을 단축시키는 효과가 있었다. Objectives : The purpose of this study was to investigate the effects of cognitive differentiation training of Integrated Psychological Therapy(a training program of executive function, concept formation, language, and abstraction) on micro-level cognitive function such as attention, memory and reaction time in patients time in patients with schizophrenia. Methods : Twenty-four inpatients diagnosed as schizophrenia using DSM-IV were randomly assigned to 2 groups. The training group went through a total of 12 sessions of cognitive differentiation training for 4 weeks. The control group received psychoeducation program during the same period. Wechsler Memory Scale-Revised and Decision-Reaction Timer of Vienna Test System were administered to all patients, both before and after the training program. Results : 1) In the attention and concentration scores of Wechsler Memory Scale-Revised, between group, within group and interaction effects of training were not significant. 2) In the short-term memory scores of Wechsler Memory Scale-Revised, within group effect of training was significant(F(1,24)=10.46, p〈0.05), but the between group and interaction effects did not reach significance. 3) In the long-term memory scores of Wechsler Memory Scale-Revised, within group effect of training was significant(F(1,24)=15.09, p〈0.05), but the between group and interaction effects did not reach significance. 4) In the reaction time scores of Decision-Reaction Timer, interaction effect of training was significant(F(1,24)=5.18, p〈0.05). 5) In the motor time scores of Decision-Reaction Timer, between group, within group and interaction effects of training were not significant. 6) In the decision time scores of Decision-Reaction Timer, interaction effect of training was significant(F(1,24)=6.00, p〈0.05). Conclusion : Our findings suggest that cognitive differentiation training of Integrated Psycho-logical Therapy is partly effective on improving micro-level cognitive functions such as reaction time(especially, decision time) in patents with schizophrenia.
