Normal values of serum electrolytes were determined for adult 36 females and 18 males, 1 to 6 years old, of Jindo dogs. The mean values, standard deviation and rangEs of sodium, potassium, chloride, calcium and inorganic phosphorus were studied and data analyzed to determine whether differences existed between the values of female and those of male dogs. The results obtained in this study were as follows: 1. The mean value of serum sodium was $143{\pm}1.5mEq/liter$, ranged from 138mEq/liter to 152 mEq/liter. The mean values for the females and males were $144{\pm}2.0mEq/liter$ and $142{\pm}1.7mEq/liter$, respectively. They showed that the female dogs had a tendency toward higher values than the male dogs, but no significant sex-related differences were observed. 2. The mean value of serum potassium was $4.6{\pm}0.2mEq/liter$, ranged frem 3.5mEq/liter to 6.0mEq/liter. The mean values for the females and males were $4.7{\pm}0.4mEq/liter$ and $4.5{\pm}0.3mEq/liter$. They showed that the female dogs had a tendency toward higher values than the male dogs, but sex differences were not found to be significant. 3. The mean value of serum chloride was $103{\pm}3.0mEq/liter$ ranged from 95mEq/liter to 117mEq/liter. The mean values for the females and males were $103{\pm}3.2mEq/liter$ and $103{\pm}3.3mEq/liter$, no sex differences showed. 4. The mean value of serum calcium was $5.2{\pm}0.1mEq/liter$ ranged from 4.7mEq/liter to 5.8mEq/liter. The mean values for the females and males were $5.4{\pm}0.1mEq/liter$ and $5.2{\pm}0.09mEq/liter$ respectively, no significant sexd iffere-nces were observed. 5. The mean value of serum inorganic phosphorus was $4.3{\pm}0.7mg/100ml$, ranged from 2.5mg/100ml to 5.8mg/100ml. The mean values for the females and males were $4.3{\pm}0.9mg/100ml$ and $4.1{\pm}0.8mg/100ml$, respectively, no sex differences showed.

This study of the characteristics and the relationships of children's emotional intelligence (EQ) and self-esteem had a sample of 1060 5th grade children. The rank order of four EQ factors from highest to lowest was "perception of emotion", "other-regulation and self-expression", "self-regulation and emotion utilization", and "empathy". Among self-esteem factors, "general self-worth" had the highest correlation with overall self-esteem; "physical appearance" was most strongly correlated with "general self-worth". Relationships between EQ and self-esteem showed that higher EQ was associated with higher self-esteem. Among EQ factors, "other-regulation and self-expression" was the strongest predictor of "behavioral conduct." The next strongest predictor of self-esteem among EQ factors was "self-regulation and utilization of emotion". Other self-esteem factors well predicted by EQ were "general self-worth", and "scholastic competence".

본 연구는 EQ-5D를 이용하여 소득계층에 따른 노인들의 건강불평등을 측정하였다. 특히 건강불평등의 다양한 측면을 파악하기 위하여 집중지수를 EQ-5D의 하위차원 및 노인들의 하위집단에 따라 분해(decomposition)하였다. 분석 자료는 2010년 국민건강영양조사 원자료가 사용되었으며 이중 60세 이상인 자를 노인으로 정의하여 분석하였다. 본 연구의 분석결과를 요약하면 다음과 같다. 첫째, 노인들의 EQ-5D 집중지수는 .0254를 기록하였다. 이는 고소득층에 유리한 불평등이 있음을 의미한다. 나아가 EQ-5D를 구성하는 모든 하위차원 즉, 운동능력, 자기관리, 일상활동, 통증/불편, 불안/우울, 기능악화 등에서도 불건강이 저소득층에 집중되어 나타났다. 둘째, EQ-5D 집중지수를 가장 많이 설명하는 하위차원은 운동능력으로 EQ-5D 집중지수의 35.8%를 설명하였다. 그 다음으로 통증 및 불편(17.7%), 기능악화(17.7%), 일상관리(14.6%) 등의 순으로 설명력이 높다. 이러한 결과는 전 연령층을 분석한 선행연구의 결과와 대조를 이루는데, 선행연구들에서 기여도가 매우 낮았던 운동능력(3.9%)이 크게 상승한 반면 불안/우울의 기여도는 약화되었다. 셋째, 성별, 지역, 배우자 유무에 따라 EQ-5D 집중지수를 분해한 결과 세 집단이 집중지수를 설명하는 정도는 비슷하게 나타났다. 세 집단은 각각 건강형평성의 1/10정도를 설명하였다. 넷째, EQ-5D 집중지수를 하위집단에 따라 분해한 결과, 남성보다는 여성이, 도시지역보다는 농어촌지역이, 그리고 배우자가 있는 노인보다는 없는 노인의 내부불평등이 더 크게 나타났다. 내부 불평등이 큰 세 집단의 경우 모두 EQ-5D 평균값도 낮았는데, 이는 저소득 여성노인일수록, 농어촌지역 저소득 노인일수록, 배우자가 없는 저소득 노인일수록 건강관련 삶의 질이 떨어짐을 의미하는 것이었다. 마지막으로 하위집단의 내부불평등이 집중지수를 설명하는 정도는 여성노인집단, 도시지역 노인집단, 배우자가 있는 노인집단이 크게 나타났다.

This study was conducted to investigate sodium and potassium balances, as well as correlations among the relating factors in adult males and females. We collected blood, urine and feces samples as well as a dietary intake survey from 50 subjects. Then, we analyzed the sodium and potassium contents in blood, urine and feces, and evaluated their state of balance. The average ages of the study targets were 24.7 years old for males and 22.8 years old for females. The daily energy intake by the males was 1733.4 kcal and by the females was 1570.3 kcal. Sodium intakes were 138.3 mEq and 127.5 mEq for males and females, respectively. Potassium intakes were 43.1 mEq and 49.3 mEq, respectively. The daily excretions of sodium through urine were 136.6 mEq by males and 97.0 mEq by females and the excretions through feces were 2.2 mEq and 2.0 mEq, respectively. The daily excretions of potassium through urine were 20.2 mEq and 16.5 mEq by males and females respectively, and the excretions through feces were 7.7 mEq and 7.5 mEq male to female. The retention rates of sodium were 11.7% and 14.1% male to female, respectively, and the apparent absorption rates were 98.5% and 97.8%. Additionally, the retention rates of potassium were 32.9% and 39.8% and the apparent absorptions were 81.9% and 81.3%, both male and female. It was noted that, overall, the sodium intake of adult males and females is still higher than the recommended daily sodium intake, while the potassium intakes and excretions were found to be lower. Based on the results of this study, nutritional guidance and education is recommended to encourage decreased sodium intake and increased potassium intake, according to recommended standards.

Objectives : The purpose of this study was to assess the health-related quality of life (HRQoL) for patients with panic disorder using EQ-5D and EQ-VAS, and to examine the relationship between health-related quality of life and clinical outcomes following treatment. Methods : 29 patients with panic disorder were recruited from the Seoul Metropolitan area and 20 patients were followed up after two months of outpatient treatment. The Panic Disorder Severity Scale (PDSS) was used to assess the severity of the panic disorder and the changes in symptoms. HRQoL was assessed with EQ-5D and EQ-VAS at baseline and at two months of treatment. Results : All enrolled panic disorder patients showed significantly impairment of HRQoL in view of the subscales of EQ-5D, EQ-VAS index scores. The severity of PDSS was correlated the HRQoL in the panic patients. After treatment, the EQ-5D, EQ-VAS index scores showed significant improvement. Conclusion : Panic disorder patients suffer from lower HRQoL as well as from symptoms of the disorder. They showed clinical improvement and a restored HRQoL with treatment. These outcomes suggest using the EQ-5D, EQ-VAS such as the HRQoL in the assessment of patients with panic disorder is essential.

Since the open heart surgery was performed, various kinds of problem concerning the extracorporeal circulation[EGG] have been known. The author investigated the changes of serum potassium ion before and after ECC among the 102 patients including 63 adults and 39 children who underwent open heart surgery from April 19S6 to February 1990 in Chung-Ang University Hospital. The mean values of potassium ion before and after ECC were analyzed according to the influencing factors such as priming solution, aortic cross clamping time, the underlying disease, the type of oxygenator and the amount of cardioplegic solution. The results were as follows: l. In the aspect of congenital and acquired heart disease groups, the mean values of serum potassium ion[Mean\ulcornerS.D.] before and after ECC revealed a significant change only in the acquired heart disease group[congenital; 3.87$\pm$0.48mEq /L vs. 4.05$\pm$0.73mEq /L, P>0.05, acquired: 4.40 $\pm$0.98mEq /L vs. 4.11$\pm$0.52mEq /L, P<0.05]. Between the two groups, the changes of the mean values of serum potassium ion before and after ECC were significant[P<0.05]. But all values were within normal limits. 2. In the aspect of the aortic cross clamping time[ACCT], in the groups of less or more than 120 minutes, the mean values of serum potassium ion before and after ECC revealed no significant change[less than 120 min; 3.97+-0.64mEq /L vs. 3.99+0.67mEq /L, P>0.05, more than 120 min; 4.34+0.82mEq /L vs. 4.27+0.62mEq /L, P>0.05], and The changes of mean values of serum potassium ion between the two groups were not significant[P>0.05]. 3. In both membrane and bubble oxygenator groups, the mean values of serum potassium ion before and after ECC did not reveal a significant difference respectively [membrane; 4.74 +1.40mEq /L vs. 4.28+0.3lmEq /L, P>0.05, bubble; 4.02 +0.60mEq /L vs. 4.05 L0.68mEq/L, P>0.05], and no differences between the membrane and bubble oxygenator groups[P >0.05]. 4. In the groups of membrane and bubble oxygenator in the cases of ACCT more than 120 minutes, the mean values of serum potassium ion before and after ECC did not reveal a significant difference respectively[membrane; 4.36$\pm$0.85mEq /L vs. 4.37$\pm$0.26mEq /L, P>0.05, bubble; 4.30 $\pm$0.80mEq/L vs. 4.23$\pm$0.67mEq/L, P>0.05], and no differences between the two groups[P>0.05]. 5. In spite of increased amount of cold potassium cardioplegic solution, the mean values of serum potassium ion before ECC were similar to those of serum potassium ion after ECC[less than 20ml /kg
