The study was designed to assess the zinc nutritional status by gestational age of pregnant women visiting in public health centers in Ulsan. The subjects were divided into 3 trimester by last menstrual period(LMP). Interview for dietary zinc intake and general characteristics of each subjects was given and biochemical analysis of blood and urine was performed. Serum zinc concentration and urinary zinc excretion were analyzed by Flame Atomic Absorption Spectrophotometer, and alkaline phosphatase(ALP) activity was analyzed by Bowers & McComb\\`s method with Schimadzu automatic analyser. Also urinary creatinine was analyzed by Hawk\\`s method. Mean intake of zinc was 6.61${\pm}$1.57mg and did not meet the RDA(44.1% of RDA) for pregnant women by gestational age. Zn intake of 3rd trimester was significantly increased but dietary zinc was almost supplied with cereal and grain (47.30%) which were reported with low zinc availability due to phytate. Mean concentration of serum Zn in 1st trimester was 86.4${\pm}$10.5$\mu\textrm{g}$/dl, was 72.4${\pm}$10.3$\mu\textrm{g}$/dl in trimester and 65.1${\pm}$10.8$\mu\textrm{g}$/dl in 3rd trimester and was declined significantly by gestational age during pregnancy. In was concluded that a decline in serum Zn by gestional age was not influenced by amount of Zn intake. However ALP activity and urinary zinc excretion increased significantly by gestational age. Zinc nutritional status of pregnant women was not confirmed yet due to the physiological changes during pregnancy. However, the pregnant woman may be in a marginal zinc deficient status because of low amount of Zn intake and low bioavailability of Zn from dietary sources.

Purpose: This study was conducted to monitor the development of Korean premature infant at six-month age and to explore factors related to developmental status of the premature infants. Methods: Participants were 58 premature infants whose corrected age was six-months old and their mothers. The developmental states of infants were followed-up with the Korean Prescreening Developmental Questionnaire (KPDQ-II). Clinical characteristics of the infants were identified from the medical records. Other characteristics including Edinburgh Postnatal Depression Scale, husband's support, social support, and mother-infant attachment were assessed using self-report questionnaires from the mothers. Results: Forty three percent of the infants were in the group of questionable status of development on the KPDQ-II. There were significant differences between the premature infants with normal developmental status and those with questionable developmental status depending on gender ($x^2$=5.03, p=.034), gestational age (t=2.59, p=.012), hospital stay (p=.013), revised Neurobiologic Risk Score (p=.005) and mother-infant attachment score (t=2.12, p=.040). Conclusion: Mother-infant attachment, as well as physiological state of premature infants, is an important variable in early development. Therefore, early monitoring for the development has to be done for physiologically vulnerable premature groups. Also, providing proper nursing support to improve maternal attachment needs to be considered.

The blood pressure measuring equipment, which is being supplied and used most widely by being recognized convenience and accuracy now generally, is oscillometric blood pressure monitor. However, a change in blood pressure is basically influenced by diverse elements such as each individual's physiological status and physical condition. Thus, the measurement of blood pressure, which used single element called oscillation in blood pressure of being conveyed to cuff, is not considered on physiological elements such as cardiovascular system status and blood vessel stiffness index, and on external elements, thereby being quite in error. Accordingly, this study detected diverse bio-signals and body informations in each individual as the measurement subject such as ECG, PPG, and Korotkoff Sound in order to enhance convenience and accuracy of measuring blood pressure in the complex measurement equipment, thereby having extracted regression method for compensation in error of oscillometric blood pressure measurement on the wrist, and having improved accuracy of measuring blood pressure. To verify a method of improving accuracy, the blood pressure value in each of SBP, DBP, MAP was acquired through 4-stage experimental procedure targeting totally 51 subjects. Prior to experiment, the subjects were divided into two groups such as the experimental group for extracting regression method and the control group for verifying regression method. Its error was analyzed by comparing the reference blood pressure value, which was obtained through the auscultatory method, and the oscillometric blood pressure value on the wrist. To reduce the detected error, the blood pressure compensation regression method was calculated through multiple linear regression analysis on elements of blood pressure, individual body information, PTT, HR, K-Sound PSD change. Verification was carried out on improving significance and accuracy by applying the regression method to the data of control group. In the experimental results, as a result of confirming error on the reference blood pressure value in SBP, DBP, and MAP, which were acquired through applying regression method, the results of $-0.47{\pm}7.45$ mmHg, $-0.23{\pm}7.13$ mmHg, $0.06{\pm}6.39$ mmHg could be obtained. This is not only the numerical value of satisfying the sphygmomanometer reference of AAMI, but also shows the lower result than the numerical value in SBP : $-2.5{\pm}12.2$ mmHg, DBP : $-7.5{\pm}8.4$ mmHg, which is the mean error in the experimental results of Brram's research for verifying accuracy of Omron RX-M, which shows relatively high accuracy among wrist sphygmomanometers. Thus, the blood pressure compensation could be confirmed to be made within significant level.

This study investigated the relaxation effects of Crataegi Fructus(CF, Crataegus pinnatifida Bunge) on the contraction evoked by phenylephrine in rabbit carotid artery, and also analyzes antioxidative status in vitro. CF revealed siginificant relaxation on phenylephrine-induced arterial contraction. It's relaxant effect statistically significant in both in the presence of endothelium and absence of endothelium, but statistically exerted more strong relaxation in the presence of endothelium. CF increased in vitro nitric oxide(NO) production in dose-dependent manner. Also, they reduced malondiaidehyde(MDA) concentrations, phosphatidyl choline-liposome(PCOOH) contents, linoleic acid-induced lipid peroxidation and exerted 1,1-diphenyl-2- picryl-hydrazyl(DPPH) radical scavenging effect, in vitro. These results indicate that Crataegi Fructus would be effective in relaxing arterial contraction and it's antioxidative effects may be involved in endothelium-dependent relaxation of artery via vascular protective properites.

This study was performed to estimate serum 25-hydroxyvitamin D level and to evaluate the relationship between serum 2S-hydroxyvitamin D level and associated factors. The subjects were 61 premenopausal working women aged 30 - 49 y in Busan. The serum 25-hydroxyvitamin D level was measured by radioimmunoassay. Data for physiological characteristics, lifestyle factors, physical activity and nutrient intake were assessed by questionnaire including information about outdoor activity time, daily activity diary and 24 hr recall method. The mean vitamin D intake was 3.12 ug, which corresponded to $62.5\%$ of the Korean RDA. The mean level of serum 25-hydroxyvitamin D was 31.0 ng/mL. Low 25-hydroxyvitamin D (<25 nmol/L) was not found in the subjects. The serum 2S-hydroxyvitamin D level showed positive significant correlations with exercise hours, daily energy expenditure, hours of outdoor activity per weekdays (p < 0.001, P < 0.05, P < 0.05). Exercise hours were found to be the most important determinant of serum 25-hydroxyvitamin D level. Therefore nutritional education for increasing hours of physical activity including indoor and outdoor exercise, is needed for premenopausal working women to increase vitamin D status.

Purpose: This study was done to evaluate the effects of a fluid intake intervention on increasing fluid intake and ameliorating dehydration status in elders admitted to long-term care hospitals. Methods: A nonequivalent control group, pretest and posttest design was used. The experimental group of 39 participants received the 4-week intervention while the control group of 38 participants received routine care. Outcome variables were daily fluid intake and physiological indexes such as blood urea nitrogen and creatinine ratio (BUN/Cr), urine specific gravity (USG), and urine color. Results: After the intervention to increase fluid intake, there were statistically significant increases in daily fluid intake, normal BUN/Cr, and USG in the experimental group. However, a statistically significant improvement in normal urine color was not found for either group. Conclusion: The findings of this study demonstrated that the fluid intake intervention improved hydration status of the experimental group participants. Consequently, it was confirmed that the intervention is considered to be effective in preventing dehydration which occurs frequently in older adults in long-term care facilities and, thus this intervention may contribute to preventing various health issues resulting from dehydration.

Vegetables are liberally taken to enhance the mineral, vitamin, and rouphage value of the diet. And calcium is an essential mineral at all ages, although the daily requirement varies with physiological status of the individual. On the other hand, oxalic acid is an unwanted constituent of several clinical disorders. It is therefore necessary to take into account the calcium as well as the oxalic acid content of the various calcium, foods. Oxalic acid, calcium, calcium/oxalic acid ratio and available calcium have been determined in 31 kinds of the Korean common vegetables. The results are summarized as follows; 1. The highest content of oxalic acid has been recorded in Amaranth. spinach and beet. It is respectively 1,100mg%, 619mg%, 550mg% in fresh sample. It is comparatively high in Leek, leavels of perilla, Mugwort, Chyi-leaves, green red pepper, Burdock. 2. Many vegetables have been calculated as below 2.0 in the calcium/oxalic acid ratio. 3. Avaiable calciumis much in Malaolitoria, Lettuce, Green onion whole, Green garlic, Wild onion, Cabbage and Radish root. 4. A food calendar is suggested as a guide to the proper selection of food items for normal individuals and for those suffering from urolithiasis, cardiovascular disease or calcium deficiency status.

This study was performed to estimate serum 2S-hydroxyvitamin D (25-OHD) level in wintertime and to evaluate the relationship between serum 25-OHD level and associated factors in 50 premenopausal working women aged 30-49 y in Busan. The serum 25-OHD level was measured by radioimmunoassay. Data for physiological characteristics, lifestyle factors, physical activity and nutrient intake was assessed by questionnaire including information about outdoor activity time, daily activity diary and 24hr recall method. The mean vitamin D intake was $4.24{\mu}g$, which corresponded to 84.9% of the Korean RDA. The mean level of serum 25-OHD was 25.7 ng/mL. Vitamin D deficiency (25-OHD < 7nmol/L) and toxicity $(25-OHD{\geq}75\;nmol/L)$ were not found in the subjects. However, the prevalence of vitamin D insufficiency (25-OHD < 15 nmol/L) and hypovitaminosis D (25-OHD < 30 nmol/L) were 12% and 60% respectively. The serum 25-OHD level showed positive significant correlations with the duration of outdoor activity per weekdays (p < 0.05). Our findings suggest that hypovitaminosis D was common in the subjects in wintertime. So nutritional education for increasing outdoor activities is needed for premenopausal working women to increase vitamin D status in wintertime.
