Purpose : This study was carried out to identify the factor of decisional balance for exercise. This was composed of a set of variables at the level of decision making when the elderly decide to do exercise. It was used to classify and identify the characteristics of the stages of change for exercise to which the elderly belong, and was used to identify the variables of decisional balance which influence the stage of change for exercise in the elderly. Methods : Convenient samples of 198 subjects over age 60 in Seoul(mean age=70) were selected from community living, mentally competent older adults and the data was collected from April 1, 1999 to May 31, 1999. The research instrument was the Decisional Balance Measure for Exercise(Marcus & Owen., 1992), Stage of Change Measure(Marcus et al, 1992). The data was analyzed by SAS Program. Results: 1. According to stage of change measure, without missing data, 191 subjects were distributed in each stage of change for exercise : 50 subjects(26.1%), 7 subjects(3.6%), 52 subjects(27.2%), 4 subjects(2%), and 78 subjects(40.8%) belonged to the pre-contemplation stage, contemplation stage, preparation stage, action stage and maintenance stage. 2. Factor analysis identified 3 factors of decisional balance as appropriate factors for excise of the elderly and named by researchers; 1)'Perceived Physical-psychological benefit', 2)'Perceived Physical-psychological burden', and 3)'Perceived time burden'. 3. The analysis of variance showed that the two components Perceived Physical - psychological benefit(F=45.95, p=.0001), and Perceived Physical-psychological burden(F=26.52, P=.001) were significantly associated with stage of change. 4. Through the discriminant analysis, it was found that both 'Self Perceived Physical-Psychological benefit' and 'Perceived Physical-Psychological burden' were the influential variables in discriminating the three stages of change(pre-contemplation, preparation, and maintenance). Conclusion: Results are consistent with the application of the Transtheoretical model, which has been used to understand how people change health behaviors. Even though this study is a cross-sectional, not a longitudinal study, the findings of this study give useful information for exercise intervention about especially the factors relating to decision making for exercise of the elderly in the different stages of change of exercise.

Histopathological changes and cadmium accumulations in the gills were investigated in crucian carp (Carassius auratus) exposed to 0, 0.01, 0.1, 0.5 mg/l cadmium (Cd)concentrations for 25 days. After 25 days of exposure, cadmium accumulations increased in each of the different exposure concentrations. Histopathological changes in the gills of curcian carp exposed to cadmium included the acidification of mucous cell, the terminal clubbing of lamellae, the hyperplasia of epitherial cell and the curved of secondary lamellae. The similar histopathological changes were observed once the accumulations of cadmium reached the similar levels found in the present study with the different exposure schemes. Also the acidification of mucous cell in gills appeared when cadmium accumulations reached 5 ㎍/g and more. These results suggested that histopathological changes in the gills, an appearance of mucous cell acidification, be used to estimate the relation between toxic effect and cadmium accumulations in the gills.

Background: Subclinical hypothyroidism(SCH) is a common biochemical abnormality which can be found in routine screening tests of thyroid function. We are increasingly faced with the question of whether its an indication for thyroxine replacement therapy. The effect of thyroxine replacement on lipid profile in SCH has aroused a great interest because of an association of overt hypothyroidism(OVH) with hyperlipidemia and increased risk of coronary artery disease. Method: We prospectively evaluated the changes in lipids and apoproteins before and after thyroxine replacement therapy in 23 patients with SCH and in 37 patients with OVH. We measured serum total cholesterol and triglyceride using autoanalyzer, high density lipoprotein(HDL) chole-sterol by dextran sulfate method, Apo A1 and Apo B by immunonephelometric assay. Results: Thyroxine replacement therapy significantly decreased total cholesterol, low density lipoprotein(LDL) cholesterol and apo B levels, but did not affect the level of triglyceride, HDL cholesterol or apo AI in patients with OVH. In SCH, thyroxine replacement therapy with the doses to normalize serum TSH concentrations also decreased significantly the level of cholesterol and LDL cholesterol albeit apo B levels did not change. Moreover, in most of patients with OVH (11 of 12) and in all of patients with SCH(5 of 5) who had had hyperchlesterolemia before treatment, thyroxine replament normalized their cholesterol and LDL cholesterol levels. Conclusion: In regard to the beneficial changes in blood lipid levels, patients with SCH should be treated, especially in cases who have other risk factors for the development of atherosclerosis. If thyroxine replacement only will reduce the incidence of coronary artery disease in SCH remains to be elucidated by long-term prospective studies(J Kor Soc Endocrinol 11:41-51, 1996).

The purpose of this study is to inspect effects of regular walking and barefoot walking, which is the easiest way for middle-aged women to exercise in daily life, on serotonin, cortisol, epinephrine and norepinephrine in blood and probe the differences of hormonal changes between two groups. Both of two programs were performed three times a week and each program lasted for more than 30 minutes. The group of regular walking was set at 40-60%(HRmax) and the group of walking barefoot was set at level 10-12(RPE). This research is for reducing middle-aged women's stress and helping to promote their health. All the data is processed by using the arithmetical mean and standard deviation and two-way ANOVA is used to verify differences between groups and durations. In case that there is interaction, independent t-test is used for group comparison and dependent t-test is used for duration comparison to inspect details. Degree of hypothesis acceptance is set at p<.05, p<.01, p<.00l. Firstly, the serotonin rate is reduced in both groups after conducting the programs. Significant main effect of serotonin has differences related to durations at F(1.18)=8.281, p=.01 but there's no differences between groups at F(1.18)=.289, p=.597. There is no differences in interaction as well at F(1.18)=.432, p=.520. Secondly, significant main effect of the cortisol rate in both groups after conducting the programs has no differences related to durations at F(1,18)=.292, p=.595 and there's no differences between groups at F(1.18)=.121, p=.732. There is no differences in interaction as well at F(1.18)=.899, p=.356. Thirdly, the result of paired t-test shows that epinephrine rate of the group performing regular walking is reduced more than one of those who walk barefoot at t=2.326, df=9, p=.045 and there is a difference in interaction at F(1.18)=5.815, p=.027. Lastly, the norepinephrine rate of those who take usual walks shows a meaningful difference related to durations at F(1.18)=24.505, p=.00l which is more noticeable than one of the other. However, there is no difference between groups at F(1.18)=.175, p=.680 and there is also no difference in interaction at F(1.18)=.902, p=.355. The result says that both of the programs, regular walking and walking barefoot, don't influence the amount of middle-aged women's stress positively, which is against the previous studies. It is because this research exclude other factors which can influence hormone secretion of middle-aged women such as weather, time, diet and mental state in middle age. It can be deduced that future researches to promote middle-aged women's health and decrease the symptoms of depression should include changes caused by temperature, time to exercise, exercise intensity and subject's psychological state in middle age.

Chang, Hye-Ja,Lee, Jaung-Sook,Kwak, Tong-Kyung The Korean Nutrition Society 2003 Nutritional Sciences Vol.6 No.2

To prevent food-borne diseases and ensure food safety, foodservice operators have been implementing the HACCP system in their facilities. Employees' knowledge of food safety can be improved through training and, as a result, their food safety behavior can be positively changed. A nonequivalent pretest and posttest control group model was designed to investigate the effectiveness of HACCP-based training on hospital foodservice employees' food safety knowledge and behavior, and to determine relationships between food safety knowledge and food safety behavior. The subjects used in this study were 84 hospital foodservice employees, assigned either to the intervention group (n=44) or the control group (n=40). Data were analyzed using the Statistical Package for the Social Sciences (SPSS). Descriptive statistics were computed, while the Student's t-test and ANCOVA (Analysis of Covariance) were used to investigate significant differences between groups, and the Pearson correlation was used to determine significant correlations. There were significant gains in both food safety knowledge and behavior, after the HACCP-based training. However, no significant correlation was found between food safety knowledge and food safety behavior. Based on this study we conclude that HACCP-based training is effective in improving both the food safety knowledge and food safety behavior of hospital foodservice employees.

南昌祐,具喜淑 同德女子大學校 1992 同大論叢 Vol.22 No.1

Sequential changes in the hematological parameters of peripheral blood and lipid peroxidation products of the plasma were studied after treatment with phenylhydrazine in New zealand white rabbits. Also, the biosynthesis and degradation of catalase and superoxide dismutase of red blood cells in Phenylhydrazine-treated rabbits have been investigated. The rabbits were made reticulocytotic by subcutaneous injections with neutralized phenylhydrazine (7.5mg/kg body weight) on first, second and fourth day of experimental Period. The results were summarized as follows : 1. The erythrocyte and leucocyte counts of normal rabbit was 6.09×10??/mm³ and 8.4×10³/mm³, respectively. The erythrocyte count was. decreased after phenylhydrazine treatment and reached a minimum value at the sixth day, but leucocyte count was increased after phenylhydrazine treatment and reached a maximum value at the fourth day. Platelet count of normal rabbit was 30×10³/mm³ and after treatment of phenylhydrazine, it was increased gradually and reached a maximum value at the second day, that is about 11 times increment as compared with normal value. 2. The hemoglobin concentration of phenylhydrazine treatment was decreased to half times of normal rabbit on the sixth day and the turbidity of red blood cell lysate from rabbits was risen from second day after Phenylhydrazine injection, and reached a maximum about the fourth day. 3. The reticulocyte count of rabbit blood showed gradual increase and reached a maximum value at the sixth day. The hematocrit of normal rabbit blood was 38.7%, but after treatment of Phenylhydrazine, it was decreased to 18.1% at the fourth day. 4. The hemolysis of rabbit erythrocyte was increased significantly after phenylhydrazine treatment and reached a maximum value at the sixth day, that is about 15 times as compared with normal value. The plasma TBA value of rabbit on the seventh day after phenylhydrazine treatment was produced a maximal value which is larger about 2.5 times than normal value. 5. The activities of catalase and superoxide dismutase in normal erythrocytes was about 51.22 units and 1.51 units per mg protein, respectively. In the phenylhydrazine treated rabbits, catalase and superoxide dismutase activities was maximal on sixth day and the fifth day, respectively. 6. In the Phenylhydrazine treated rabbit erythrocytes, at induction period of reticulocytosis, the kinetic constants of synthesis(Ks), degradation(Kd) and half life for catalase were 1.2700, 0.0089 and 77.9 hours, respectively. The kinetic constants of Ks, Kd and the half life for superoxide dismutase were 0.0600, 0.0144 and 48.1 hours, respectively. 7. In the Phenylhydrazine treated rabbit erythrocytes, at recovery period of reticulocytosis, the kinetic constants of synthesis(Ks), degradation(Kd) and half life for catalase were 0.9216, 0.018 and 38.5 hours. The kinetic constants of Ks, Kd and half life for superoxide dismutase were 0.0347, 0.0230 and 30.1 hours, respectively.

심혜숙,김규중,김형섭,최창근,전방욱 江陵大學校東海岸地域硏究所 1993 東海岸硏究 Vol.4 No.1

강릉수력발전소의 발전수 방류가 강릉 남대천의 수질 및 미생물 분포에 미치는 영향을 조사하였다. 정점 3 상류지역의 발전수 방류는 수질에 상당한 영향을 끼쳐 정점 3 및 정점 4의 수질은 악화되고 정점 5, 정점 6 및 정점 7의 수질은 개선되었다. 미생물 분포도 이와 유사하여 정점 3 및 정점 4의 세포수는 상당히 증가한 반면 정점 5, 정점 6 및 정점 7에서는 대체적으로 감소하였다. 이 결과로 미루어보아 강릉수력발전소의 발전수는 희석효과에 의해 수질 및 미생물 분포를 변화시키는 것으로 사료된다. The effects of water discharged from Kangnung hydropower plant on the water quality and some bacterial population of Namdaecheon Stream, Kangnung were investigated. The water discharged above station 3 affected the water quality significantly; the water quality of station 3 and station 4 took a turn for the worse, however those of station 5, station 6 and station 7 changed for the better. It was also true with the bacterial population; The number of cells of bacteria increased in station 3 and 4, but the number significantly decreased in station 5, station 6, and station 7. The data suggested the idea that the water discharged from Kangnung hydropower plant changed the water quality and some bacterial population by dilution effect.
