Objective : This study was performed to investigate the relationship between social support and quality of life among cancer patients receiving radiation therapy. Matehals and Methods : The data were collected from 98 patients, who were receiving radiation therapy at two university hospitals located in GwangUJu, used by structured questionnaire. For statistical analyses of the association between quality of life and various characteristics, data were analyzed using t-test, ANOVA, Pearson 's correlation, and multiple regression analysis. Results: 1. There were 56(57.1%) males and 42(42.9%) females. Age ranged from 21 to 82 years. The primary sites of cancer were gastrointestinal tract (24.5%), lung (23.5%), breast (21.4%), and head and neck (11.2%) in order. 2. The mean scores of social, family, and medical support were 4.30 0.58, 4.49 0.78, 4.11 0.65, respectively. The score of quality of life was 5.83 1.63 (range: 1.95 ~ 9.05). 3. An analysis of the association between several factors of patients and quality of life showed that the statistically significant factors were age, the presence of distant metastasis, family support, medical support and social support. 4. As a result of the multiple regression analysis, only social support was significant (β=0.932, P=0.02) with quality of life, but age and presence of distant metastasis were not significant. Conclusion : This suggests that quality of life in cancer patients could be improved by strengthening the social support which consists of family and medical support. Further study would be necessary to evaluate separately several aspects of quality of life among cancer patients.

Grape vinegar(A) and grape onion vinegar(B) added (3% of onion juice) were produced through two stages of fermentation(alcohol fermentation and acetic acid fermentation) to increase the grape's use. Grape wine which contained 5.6% alcohol was produced on the 3rd day of first stage. Then through the second stages, grape vinegar, of which total acidity was 5.37% was produced. The quality of (A) and (B) which was produced through the two stages of fermentation was compared with the traditional grape vinegar(C,D) in the market. The content of sugar in (D) was a little higher such as 5.4 °Brix than others. That of (A) and (B) was 5.13, 4.98 °Brix respectively. The content of remaining alcohol in (C) was high such as 0.23% comparatively, But there was no remaining alcohol in (A) and (B). The content of acetic acid was 4.3~5.3% as a major organic acid of vinegars. The content of tartaric acid was 340.0 in (A), 316.7 in (B), 322.6 in (C) and 391.7㎎% in (D). The content of lactic acid was distinctly high such as 277.4㎎% in (D). There were differences such as 9.2~15.5㎎% in the content of total free amino acids among grape vinegars. (D) contained 15.5㎎% of total free amino acid and (B) also highly such as 12.0㎎%. Potassium was high in grape vinegars. The content of potassium, sodium and copper was higher in (A) than (B).

Investigate the epidemics for influenza outbreaks. The outbreak pattern of the internal and external patients housed in the 10 designated hospitals was monitered to investigated and the characteristics of the virus isolates are as follows. 232 strains of influenza virus was isolated from the oral specimen of 1,320 respiratory disease patients in Pusan from Oct. 1998 to Jun. 1999. Among these isolates, 222 strains were A-type and the rest were B-type. The outbreak pattern for sex-and age-group is as follows. The male outbreak was similar to the female outbreak: male outbreak, 47.4% and female outbreak, 52.5%. Most of the patients were less than 10 years old. The monthly influenza outbreak was consistent from Dec. 1998 to Apr. 1999. and The 113 strains from the A-type isolates were A/Sydney/05/97(H3N2)-like, the 109 strains were A/Beijing/262/95(H1N1)-like, and all of the 10 B-type isolates were B/Harbin/07/94-like.

본 연구의 목적은 chlorhexidine(Cervitec)과 fluoride(Fluor-protector) 성분을 각각 포함한 varnish를 치아에 적용하였을 때 타액내의 mutans streptococci의 수의 감소에 미치는 효과를 알아보기 위한 것이다. 전북대학교 치과대학생 40명을 대상으로 하여 mutans streptococci 균종 수를 평가하였으며, 이들을 무작위로 네 군으로 나누어 다음과 같이 varnish를 적용하였다; A) varnish를 적용하지 않은 군(n=10), B) chlorhexidine varnish 적용군(n=10), C) fluoride varnish 적용군(n=10), D) chlorhexidine과 fluoride varnish를 모두 적용한 군(n=10), Mutans streptococci 수 측정에는 Orion diagnostica 사의 Dentocult SM을 사용하였다. Varnish를 적용하지 않은 상태에서 1차로 Mutans streptococci 수를 측정한 후 각각의 varnish를 적용하였으며, varnish 적용 12주 후 다시 측정하여 기록하였다. 모든 실험군(group B, C, D)에서 12주 후에 측정한 Mutans streptococci 수가 감소한 개체가 증가한 개체보다 많았으나 통계적으로 유의한 차이는 보이지 않았다(p>0.05). 실험에 사용된 어떠한 varnish도 적용 12주 후에 타액 내 mutans streptococci 수에 통계적으로 유의할 만한 변화를 주지는 못하는 것으로 나타났다(p>0.05). The objective of the present prospective trial was to compare the efficacy of chlorhexidine(Cervitec), Fluoride(Fluorprotector) and combination of chlorhexdine and fluoride varnishes in decreasing the level of salivary mutans streptococci. Forty healthy students of school of dentistry, Chonbuk national university were investigated to evaluate mutans streptococci(MS) counts and randomized into four groups to treat with the experimental varnishes: A) untreated group(n=10), B) chlorhexidine group(n=10), C) fluoride group(n=10), D) chlorhexidine and fluoride group(n=10). Dentocult SM^(�)(Orion Diagnostica) strip method was used for measurement of the level of mutans streptococci in saliva. Stimulated saliva were collected at baseline for mutans streptococci counts evaluation(ms1), 12 weeks later the completion of each varnish treatment, mutans streptococci counts were re-evaluated. In varnish group with chlorhexidine, fluoride and combination of chlorhexidine and fluoride, the level of mutans streptococci was lower after 12 weeks than at baseline, but there were no significant differences in saliva(p>0.05), when compared with baseline. After 12 weeks, a remarkable reduction was still found in the subjects with high level of mutans streptococci at baseline, but not different in the low and moderate level of mutans streptococci(p>0.05).

골격성 Ⅲ급 부정교합 환자에서 술전 교정전 예측치와 교정후 실측치의 차이에 관한 연구

황충주,권희정 대한치과교정학회 2003 대한치과교정학회지 Vol.33 No.1

본 연구에서는, 술전 교정전 예측전와 교정후 실측치 사이에 나타나는 오차의 크기와 정확성 및 어떠한 요소가 그러한 결과에 영향을 미치는가에 대해 평가하고자 하였다. 연세대학교 치과병원 교정과에서 골격성 Ⅲ급 부정교합ㅇ로 진단되어 술전 교정치료 및 양악수술을 받은 환자 가운데 조건에 부합되는 45명(남자 17명, 여자 28명)을 선별하여, 초진 상태를 T1, 교정 치료전 예측치를 T2, 술전 교정후를 T3로 정의하고 각각의 계측치를 수평과 수직좌표로 나누어 측정하였다. 또한 환자의 어떠한 진단적 요소가 술전교정의 예측치와 실측치 사이의 차이에 영향을 미치는지 알아보기 위해 연구대상을 arch length discrepancy (ALD), 상·하악 전치의 치축(U1 to SN, IMPA), curve of Epee(COS), 발치 여부, 발치한 치아의 종류 등에 의해 여러 군으로 분류하여 유의성을 평가하였으며 다음과 강은 결과를 얻었다. 1. U6mbc, L1x의 수평 좌표와 Uli, Ulx, U6me, U6mbc, L6mbc의 수직 좌표에서 예측한 위치와 수술직전의 실제 위치의 차이가 유의성(p<0.05) 있게 나타났다. 2. 예측의 정확성은 수평적인 차이의 예측에 있어서 수직적인 차이의 예측에 비해 상대적으로 높게 나타났다. 3. 하악에서보다 상악의 많은 계측점에서 예측치와 실측치 사이의 유의한 차이(p<0.05)가 관찰되었다. 4. 상악의 경우 발치 여부 및 발치한 치아의 종류, ALD의 양에 따라 상악 전치와 제1대구 위치의 예측에 유의한 차이(p<0.05)를 보였으며, 하악의 경우에는 ALD의 양과 IMPA에 따라 하악 전치와 제1대구의 위치의 예측에 유의한 차이(p<0.05)를 나타냈다. 이번 연구에서 얻은 결과를 통하여 술전 교정전 예측치와 실측치 사이의 오차의 정도와 그것에 영향을 미치는 요소들을 분석하고 희귀 계수를 구함으로써, 악교정 수술을 동반한 교정 환자의 치료 계획 시 예측의 정확성을 높일 수 있을 것으로 생각된다. 또한 수직적인 예측에 있어서는 앞으로 더 많은 연구가 이루어져야 할 것으로 생각된다. The Purpose of this study was to find out and evaluate discrepancies between preoorthodontic prediction values and actual postorthodontic values and factors contributing to it 45 patients(17 male, 28 female) who were diagnosed as skeletal Class Ⅲ malocclusion and received presurgical orthodontic treatment and orthognathic surgery at Yonsei university dental hospital. Lateral cephalograms were analyzed at oretreatment(T1), orthodontic prediction(T2), immediately before surgery(T3) and designated the landmark as coordinates of X and Y axes. The samples were divided according to ALD, upper and lower incisor inclination(U1 to SN, IMPA), COS, extraction, the position of extracted teeth and the statistical significance was tested to find out the factors contributing to the prediction. The results were as follows : 1. Differences between preorthodontic prediction values and actual postorthodontic values(T2-T3) were statistically significant(p<0.05) in the x coordinates of U6mbc, L1x and in y coordinates of U1i, Ulx, U6me, U6mbc, L6mbc 2. The accuracy of prediction is relatively higher in horizontal changes compared to vertical changes. 3. The statistical significance(p<0.05) between prediction and actual values is observed more in the landmarks of the maxilla than the mandible. 4. differences between prediction and actual values of incisor and first molar were statistically significant(p<0.05) according to extraction vs non-extraction, extraction type, ALD in the maxilla and according to ALD< IMPA in the mandible. Discrepancies between preorthodontic prediction values and actual postorthodontic values and factors contributing to the prediction must be considered in treatment planning of Cl Ⅲ surgical patients to increase the accuracy of prediction. Furthermore future investigations are needed on the prediction of vertical changes.

The aim of this research is to explore the potential of analogy and metaphor as design strategies for supporting the creative design thinking. For the empirical research on analogical and metaphoric process in designing, we conducted design experiments that consist of three different conditions of given items as stimulation for design inspiration: baseline, surrealist paintings, and housing design collections. The results were analyzed using a protocol analysis in order to obtain more systmatic interpretation of the design processes and strategies. As a result, it was noted that students are more apt to read visual information rather than semantic information in the given items. Instead of the representation of their senses or feelings from the paintings, they visualized the analogical images of the paintings for the design representation. However, analogical and metaphoric thinking derived from the given items seem change a designer’s perspective, thus bring a novel interpretation on design problems, and eventually more creative and meaningful design ideas. An extended research using one-semester training and observation of the design studio process is introduced as a follow-up study for this paper. This research will investigate the long-term effect of the analogy and metaphor on the design thinking.

쌍태아에서 제 1태아의 분만 후 제 2태아의 지연분만 : 중례보고

With the widespread use of fertility medications and techniques of in vitro fertilization, multiple gestation has become epidemic in modern obstetric practice. Delivery of the initial fetus in a multiple gestation usually is followed by delivery of the subsequent fetus or fetuses shortly thereafter. However in rare circumstances, the delivery is delayed for days due to disappearance of uterine contraction after delivery of the first fetus. When uterine activity ceases after the delivery of the first neonate, a policy of nonintervention may be considered in case of an immature or very premature delivery, in order to achieve a gestational age for the remaining fetus(es) more compatible with neonatal survival. We report a case of twin gestation with prolongation of the delivery interval between the twins for 46 days.
