Elderly people comprise an increasing proportion of the population, and nutritional impairments may contribute to health problems among this group. This study was conducted to evaluate the nutritional status by Mini-Nutritional Assessment (MNA) and to identify relationships among anthropometric measurements, biochemical indicators, bone Mineral Density (BMD) and MNA results among older adults (${\geq}$65 yrs, n=98, 66.7${\pm}$2.5 yrs; M=52, F=46, BMI 24.5${\pm}$2.8 $kg/m^2$) at a Health Care Center. A dietitian administered MNA and collected anthropometric measurements (weight, height, waist circumference), biochemical indicators (albumin, hemoglobin, hematocrit, TLC, glucose, lipids) and the BMD (spine, femur, F=46). Subjects were grouped into a normal nutrition group (0~2 risk factors of malnutrition) and a high risk of malnutrition group (>=3 risk factors of malnutrition) based on their risk factor status for malnutrition. The risk factors for malnutrition include age ${\geq}$65 years, PIBW <90%, albumin <3.5 g/dl, TLC <1,500%, Hgb <14 g/dl (men), Hgb <10 g/dl (women), loss of appetite and weight loss 1~3 kg/last 3 months. In addition, subjects were grouped into a normal, osteopenia and osteoporosis group by BMD. We found that 12% of the subjects were at risk of malnutrition (MNA score, 21.4${\pm}$2.1) and that 88% were well nourished (27.3${\pm}$1.5) according to the MNA. Full-MNA scores were positively and significantly (p<0.05) associated with BMI, mid-arm circumference (MAC), calf circumference (CC), albumin and hemoglobin, respectively. The full-MNA score of the high risk of malnutrition group (23.0${\pm}$3.8) was lower than that of the normal nutrition group (27.0${\pm}$2.1) (p<0.05). In addition, the Full-MNA score was negatively associated with the risk factor of malnutrition (r=－0.35, p=0.0004). We found that 39.1% of the subjects had osteoporosis, 45.7% had osteopenia and 15.2% were normal according to their BMD. The MNA score of osteoporosis group (24.58${\pm}$3.3) was lower than that of the normal (27.4${\pm}$1.1) and osteopenia group (26.9${\pm}$1.5) (p<0.05). These results suggested that MNA can be useful as a nutritional screening tool of older adults in Health Care Centers.

With advances in neonatal medicine, smaller and sicker infants are surviving premature birth. As these tiny patients battle for their lives, their parents also struggle with psychological consequences of an unexpected role. The birth of a sick infants has long been documented as stressful events for the parents. High stress levels may alter parents' interaction with their baby and impair their communication with health professionals, which can in turn affect parents' participation in care planning and decision making. Nursing interventions aimed at reducing the parental stress and anxiety levels during this crisis may have a positive impact on their ability to form an attatchment to their baby and make prudent decisions about his care. The planning of such interventions would be inhanced if the contributions of various factors to increased parental stress levels were identified. This descriptive study was conducted to understand the contents and degree of parental stress in the NICU during their premature's hospitalization, and to give a baseline data in developing nursing intervention program. Subjects were the 60 mother of hospitalized newborn in NICU of 2 University Hospital in Taejon City from April 1st, 1999 to June 30th, 1999, who agreed to take part in this study. The instrument used in this study were Parental Stressor Scales:NICU(PSS:NICU) developed by Miles et al.. and validated by 3 NICU practitioners and 3 child health nursing faculties. The questionnaire has 4 dimensions and 45 items; sight and sounds of NICU(5 items), babies' appearance and behavior nursing intervention(19 items), parental role alteration and relationship with their baby(10 items), health team communication(11 items). The questionnaire asks parents to rate each item on a five-point Likert type scale that ranges from "not stressful" (1) to "extremely stressfu1"(5). Total scores representing overall stress from the NICU environment are calculated by summing response to each item. A high score indicates high stress. A subscale score is calculated by summing the responses to each item in the subscale. Cronbach's ${\alpha}$ coefficients were .93. The data was analyzed as average, Frequency, Standard deviation, t-test, ANOVA, Pearson correlation coefficient by use of SPSS/PC+. The results of this study is summarized as follows ; 1. The total perceived stress level score of mothers of premature baby was slightly high($3.66{\pm}1.1$). The highest scored dimension was 'relationship with their baby and parental role change'($4.21{\pm}0.9$), and next were 'appearance and behavior of the baby'($3.92{\pm}1.1$), 'communication with health team'($3.32{\pm}1.3$), 'sight and sounds of NICU'($3.30{\pm}1.1$). 2. There were statistically significant correlation noted ; mother's perceived severity of the baby's condition(F=8.0012, P= .0125) and baby's gestational age(r = -.4724, P = .0500). In summary, information about physical environment of NICU, the mother's perceived severity of premature baby's state, maternal role change related variables and the knowledge of characteristics of premature baby must be included in nursing intervention program of mother's of premature baby in reducing the parental stress and anxiety level. It is suggested that each NICU needs to develop a nurse managed supportive care program for parents of premature baby. Also, it is suggested that there need to investigate the coping mechanism of mother of premature baby.

This paper focused on providing the groundwork for the development of proper nursing interventions to enhance the quality of life for the elderly by identifying the factors that may affect their health beliefs and behaviors. A survey was conducted on a group of people aged between 60 and 86 years residing in S and K cities from January to March of 2003, who agreed to participate in the research. Data was collected using instruments measuring health beliefs and health behaviors, and was analyzed by using SPSS. The results of this study are as follow. 1) Those in the group were aged between60 and 86 years, and the average age was 66.94 years old. Most of them were living together with their spouses. From the survey, 83.5% replied "above average" on the question regarding their current health condition, whereas, 46.0% mentioned that they had some sort of diseases. 2) Overall average score of the health belief was 516.05, with a mean $3.71{\pm}4.07$. This indicates that the studied group held a high level of health belief, which affects their attitude and intention to lead a healthy life by placing the present life under control in harmony with nature. 3) Overall average score of the health behaviors was 392.24 with a mean $2.82{\pm}.52$. For health purposes, the behaviors that the elderly people were taking were mostly static ones requiring a low level of activity. The analysis showed that they generally were involved in self-trained, individualized health care. Thus, the elderly place a higher priority on regular dietary behaviors than on physical activity. 4) The correlation between health belief, a cognitive aspect on health, and health behaviors, a behavioral aspect showed a very high linear relationship (r=.520, p<.000). Consequently, it is found that those who have higher cognitive health belief are involved in higher level of behavioral health practice. These findings concluded that the Korean elderly have good health beliefs, well controlling their minds and being harmonious with nature. Health behaviors that they are engaged in are mostly static, requiring low level activity, while they place higher priority on regular dietary habits and conducting self-trained individualized health care. Important factor affecting their health beliefs and health behaviors was found to be their health practice. Since higher health belief is highly related with good health behaviors, development of health activity programs is in need as a means for an efficient health improvement, where motivating environment may be established to enhance the health belief of the elderly and to satisfy individual values.

The purposes of this study were to find out the effects of hospice care for the quality of life of the terminally - ill patients and to analyze the relationship between the effect of hospice care and the general characteristics of subjects. The subjects of the study were 32 terminally - ill patients hospitalized in the two general hospitals in Seoul, which have the hospice care unit. The data were collected using the questionnaire with interviews. They were done from Sept.28, 1989 to March 20, 1991. The tools used for the research were 17-item questionnaire regarding general characteristics, 42-item questionnaire about the quality of life (11- item for physical, 16 for psychosocial, and 15 for spiritual). The questionnaires were to measure the duality of life by means of the measure instruments of Betty R. Farewell(1989), Stein Kaasa(1988), Palm Pamela(1987), and Hwa-sook Choi(1987). 42 items were used after pre-test. In accordance with each purpose in this study, frequency and percentage were used on the general characteristics of subjects. ANOVA, t-test, and Pearson correlation were employed to evaluate the general characteristics of subjects and different level of quality of life before-and-after hospice care. The results of the study may be summarized as follws : 1. The effects of hospice care. Main Hypothesis : “The quality of life of the terminally - ill patients will be different from before-and-after hospice care” was supported(t＝6.82, df＝31, p＝ .000). Sub Hypothesis 1 : “The quality of life of the terminally - ill patients in the physical aspects will be different from before - and -after hospice care” was not supported(t＝0.07, df＝31, p＝ .946). Sub Hypothesis 2 : “The quality of life of the terminally - ill patients in the psychosocial aspects will be different from before-and-after hospice care” was supported (t＝4.69, df＝31, p＝ .000). Sub Hypothesis 3 : “The quality of life of the terminally - ill patients in the spiritual aspects will be different from before-and-after hospice care” was supported(t＝6.64, df＝31, p＝ .000). 2. Relationship between the general characteristics of subjects and the effects of hospice care. (1) The more the number of family, the higher the quality of life in the psychosocial aspects. (2) The higher the age of the patient, the lower the quality of life in the psychosocial aspects. (3) The high educational level of patients enjoy the high quality of life in general. (4) The high religious level of petients enjoy the higy Quality of life in the spiritual aspects. As a results of analysis above : 1. The most effective aspects of the hospice care to the terminally- ill patients was spiritual aspects. The next effective aspects was psychosocial area. 2. The least effective aspcets of the hospice care to the terminally- ill patients was physical aspects. Further study is needed to improve the quality of life in the physical aspects.

The purpose of this study was to evaluate nutrients intakes, glycemic index (GI), glycemic load (GL) according to obesity index in elementary school students. The study subjects included 229 elementary school students (boys=108, girls=121) who were divided into 3 groups consisting of an underweight group (obesity index<-10%, n=58), a normal weight group (10%${\leq}$ obesity index<10%, n=130) and an overweight group (obesity index${\geq}$10%, n=41) by their obesity index. The nutrient and food intakes data obtained by a 3-day food record were analyzed. Daily dietary GI and GL values were calculated from the 3-day food record. The average age of the subjects was 11.9 years. The mean daily energy intake was 2,186.8 kcal in the underweight group, 2,123.5 kcal in the normal weight group, and 2,174.2 kcal in the overweight group. The intakes of calcium and animal calcium per 1,000 kcal in the overweight group were significantly lower than in the underweight and normal weight groups (p<0.01, p<0.05), and fruit, egg and milk intakes in the overweight group were lower than those in the underweight group (p<0.05, p<0.05, p<0.05). The mean daily dietary GI of the underweight, normal weight, and overweight groups were 67.7, 68.4 and 69.5, respectively (p<0.05). The mean daily dietary GL of the underweight, normal weight, and overweight groups were 212.8, 208.1 and 213.3, respectively. The major food source of dietary GI and GL in the three groups was rice. Other major food sources of dietary GI were croquettes, hand-rolled noddle soups, instant noddles, milk, and rice cake. Dietary GI was not significantly correlated with weight, obesity or body mass index, when adjusted for energy, carbohydrate, and dietary fiber. However, GL adjusted to energy, carbohydrate and dietary fiber tended to correlate with obesity index (r=0.126, p=0.059). These results suggest that dietary GI and GL have possibility affecting obesity-related indicators in elementary school students.

본 시험은 옥수수 주정박(corn distiller's dried grains with solubles; DDGS)의 산란계용 배합사료에 첨가시 산란계의 생산성 및 영양소 대사율, 계분의 암모니아 발생에 미치는 영향을 조사하기 위해 실시하였다. 23주령의 Hy-line Brown 계통의 산란계 216수에 DDGS를 0% 함유한 사료를 대조구(T1)로 하고, 대조구와 동에너지(TMEn 2,780 kcal/kg)-동단백질(17.0%)이 되게끔 DDGS를 각각 10%(T2), 20%(T3) 첨가한 3가지 사료를 10주간 급이하였다. 시험설계는 3처리 6반복 반복당 12수씩 완전임의 배치법을 사용하였다. 조사항목으로 사료섭취량, 산란율, 난중 및 난생산 사료요구율, 영양소대사율 및 계분의 암모니아 발생을 측정하였다. 본 시험에서 사료섭취량, 산란율, 난중 및 난생산 사료요구율 등의 산란 생산성은 모든 처리구 간에 유의적인 차이가 없었다(P>0.05). 영양소 대사율에 있어 건물의 대사율의 경우 DDGS를 첨가한 처리구들에서 유의적으로 낮게 나타났다(P<0.05). 조지방과 NDF의 대사율은 유의적인 차이가 나타나지 않았다(P>0.05). 가용무질소물의 대사율은 DDGS 첨가 수준이 높아질수록 유의적으로 낮게 나타났다(P<0.05). Ca과 P의 대사율은 DDGS 첨가구들과 대조구 사이에 유의적인 차이가 나타나지 않았다. 계분의 암모니아 발생은 DDGS 첨가수준이 높을수록 암모니아 발생이 낮게 나타났으나 유의적인 차이는 나타나지 않았다. 결론적으로 산란계사료에서 DDGS를 10~20%까지 옥수수-대두박을 대체하여 사용할 경우, 건물과 NFE 대사율을 감소시키는 효과가 있지만, 산란성적에 아무런 영향이 없이 사용할 수 있다고 판단된다.
