본 연구는 첫째, 국립서울정신병원 입원환자의 다음증유병율과 그 측정방법에 관하여 알아보고 둘째, 다음증환자의 특성을 알아보기 위해 다음증군과 대조군의 임상특성 및 생물학적 지표를 비교하였다. 국립서울서울정신병원에 입원중인 환자 634명을 대상으로 다음의 진단 기준 (1)(2)(3)중 하나라도 만족시키는 환자를 다음증 환자로 결정하였다. (1) 치료진의 보고상 입원 중 다음증으로 인한 물중독의 삽화가 명백히 있는 경우 (2) 3회 연속 뇨비증이 1.008이하이면서 하루 3리터 이상의 물을 섭취하는 경우 (3) 3회 연속 뇨비증이 1.008이하이면서 혈중 나트륨 농도가 135mEq/L이하인 경우 위 진단기준을 만족시키는 환자는 총 24명으로 전체 환자의 3.79%였다. 다음증군 20명과 대조군 20명의 임상특성 및 생물학적 지표의 비교를 통하여 다음증 환자의 특성을알아보았다. 연구 결과는 다음과 같다. 1) 유병기간, 항정신병약물 용량, 경련, 전기경련치료, 흡연, 기타 약물 사용은 두 군간에 차이가 없었다. 2) 다음증군에서 대조군보다 뇨비증이 더 낮았고 물 섭취량이 더 많았다. 일중 체중변화(normalized diu-mal weight gain)는 두 군간에 차이가 없었다. 3) 다음증군에서는 혈중 항이뇨 호르몬(antidiuretic hormone 이하 ADH)이 정상범주에 들었으나 대조군에서는 정상범주보다 높았다. 또한 다음중군에서는 혈중능동삼투농동(osmolality 이하 Osm)가 정상범주보다 낮았으나 대조군은 정상범주에 들었다. 본연구의 결과를 전체적으로 종합한다면, 저자들의 진단기준에 따른 국립서울정신병원 입원환자의 다음증 유병율은 3.79%이며 다음증 측정방법으로 치료진의 보고, 뇨비증, 혈증 나트륨 농도, 물 섭취량의 측정 등을 제시할 수 있겠다. 그리고 다음증군과 대조군의 비교에서 유병기간, 항정신병약물 용량, 경련, 전기경련 치료, 흡연, 기타 약물 사용 등의 임상특성의 차이는 없었으나 뇨비증, 물 섭취량, 혈중 ADH와 Osm 같은 생물학적지표는 분명한 차이를 보임으로서 다음증군의 특성을 나타낸다고 할 수 있겠다. We attempted to estimate the prevalence of polydipsia in psychiatric inpatients in Seoul National Mental Hospital and to find out the identification method for polydipsic patients. We also compared the clinical and biological characteristics of polydipsic patients with those in nonpolydispic patients. Methods &Results : The following inclusion criteria were applied to the study subjects for estimating the prevalence of polydipsia among psychiatric inpatients at Seoul National Mental Hospital. 1) By staff report, that a objective clinical evidence of water intoxication during hos-pitalization was noted. 2) Three consecutive urine specific gravities were all less than 1.008 and also water intake was more than 3 liters per day. 3) Three consecutive urine specific gravities were all less than 1.008 and also serum sodium level was less than 135 mEq/L. By these inclusion criteria, we found 24 polydipsic patients among 634 hospitalized psychiatric inpatients, with the prevalence of 3.79%. Comparison of the clinical characteristics and biological determinants between 20 polydipsic and 20 nonpolydipsic patients produced the following results : 1) No differences were found in duration of illness, dosage of neuroleptics, seizure history, electroconvulsive therapy history, smoking, use of medications other than neuroleptics, between the groups. 2) There was no difference in normalized diurnal weight gain. But polydipsic patients showed more water intake and lower urine specific gravities than nonpolydipsic ones. 3) Plasma antidiuretic hormone levels were within normal range and osmolalities were lower than normal range in polydipsic patients. BUT plasma antidiuretic hormone levels were higher than normal range and osmolalities were within normal range in nonpolydipsic patients. Conclusion : The prevalence of the polydipsia was 3.79%. We suggest that staff report, urine specific gravity, serum sodium level, and oral water intake can be identification markers for polydipsta. Clincal characteristics such as duration of illness, dosage of neuroleptics, seizure history, electroconvulsive therapy history, smoking, and use of medications other than neuroleptics did not differ between polydipsic and nonpolydipsic patients. But biological determinants such as urine specific gravity, oral water intake, plasma antidiuretic hormone level, and osmolality differed beween the groups. Therefore these biological determinants could be adopted as biological markers for polydipsia.

시판 된장 첨가가 스폰지 케이크 제조에 미치는 영향

오현주,김창순 한국조리과학회 2004 한국식품조리과학회지 Vol.20 No.4

The effect of commercial Doenjangs (Korean soybean pastes) on sponge cake making was studied. When Doenjang was added to egg foams at levels of 5, 10, 15 and 20%, there were no big differences in viscosity or stability of egg foams up to 15%, and thus in cake volume index, compared to those of control (without Doenjang). In the results of preference rank test, cake with 10% Doenjang was preferred to the other cakes. Therefore, it was decided that the addition of 10% Doenjang was suitable for sponge cake making. When seven commercial Doenjang products were used at 10%, there were differences in physical and sensory properties. The decreased viscosity of egg foams reduced their stability and so decreased the quality of the sponge cakes with low volume index and low texture scores. The use of Doenjangs improved the flavor of sponge cake and so countervailed the undesirable egg flavor. Especially, "C" Doenjang product, which increased the viscosity and stability of egg foams, produced good foaming ability and the highest physical and sensory quality, thus the higher overall acceptable scores than the control. It was probably due to its high amount of protein hydrolysate above 10-KDa. Consequently, the suitable amount of Doenjang was fixed at 10% and "C" Doenjang product was chosen as the best among the commercial products for sponge cake making.

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.
