This study was designed to identify premenstrual syndrome (PMS) and to investigate the correlation between premenstrual syndrome and nutritional intakes. The subjects of this study were 138 college women residing in Busan Metropolitan City. The subjects were asked to complete Menstrual Discomfort Questionnaire (MDQ) regarding PMS, food intake frequencies and nutritional intake. We studied the correlation between PMS symptoms and nutritional intake. The average height and weight of anemic subjects were 161.42 $\pm$ 3.50 cm and 51.87 $\pm$ 5.42 kg. The average BMI (body mass index, kg/$m^2$) was 19.92 $\pm$ 2.14 and PIBW (percent ideal body weight) were 93.02 $\pm$ 9.75%. Except for phosphorous, vitamin A and vitamin C intakes, the intake levels of all other nutrients were below the Korean RDA. The average calorie intake of the subjects was 1645.65 $\pm$ 352.63 kcal (82.2% of the Korean RDA) and iron intake of the subject was 11.06 $\pm$4.03 mg (69.1% of the Korean RDA) . The calcium and vitamin $B_6$ intakes were 512.26 $\pm$ 183.12 mg (73.1% of the Korean RDA) and 1.12 $\pm$ 0.14 mg (80.0% of the Korean RDA), respectively. With regard to their menstrual state, 45.9% subjects responded that their menstrual cycles were irregular. The frequency of PMS of the subjects was 30.2% (over 3 points) on 5 point scale (1 : no. 5 severe). The common symptoms of PMS of the subjects were pain (2.32 $\pm$ 1.01), negative effects (2.27 $\pm$ 0.87), behavioral changes (2.26 $\pm$ 0.85), water retention (2.07 $\pm$ 0.78) , arousal (1.79 $\pm$ 0.84) , autonomic reactions (1.77 $\pm$ 0.87) , lack of control (1.69 $\pm$ 0.75) and decreased concentration (1.68 $\pm$ 0.75) . There was significant correlation between all the PMS symptoms and calcium (p ＜ 0.01) , vitamin E (p ＜ 0.05) , carbohydrate (p ＜ 0.05) . This suggests that PMS represents the clinical manifestation of nutrient deficiency states especially calcium. Therefore we concluded that calcium supplementation is likely to be of benefit in relieving PMS symptoms.

Riboflavin, Ascorbin Acid & Vitamin D status of 74 elderly Korean (35 men and 39 women)from urban households in Incheon were evaluated by blood analysis. Mean EGR-AC value of men was 1.05 while that of women was 1.03. Marginal deficiency of riboflavin(EGR-AC 1.15-1.35) was shown in 33.3% of men and 20% of women. Average plasma ascorbic acid contents of subjects were very low and men had significantly lower amount than women(0.23mg/㎗ vs 0.44mg/㎗). The percentages of subjects who had plasma ascorbic acid less than 0.4mg/㎗ were 88.9% of men and 45% of women. Mena serum Calcium, Inorganic phosphate contents and mean serum ALP activity of men were 9.97mg/㎗, 3.28mg/㎗ and 61.85 Unit/L respectively and those of women were 9.78mg/㎗, 3.49mg/㎗ and 67.80Unit/L respectively. From these results, Vitamin D status of subjects was considered to be normal.

Originally, vitamin K was defined as a factor for blood coagulation. Now more attention is focused on vitamin K for bone metabolism and bone health. Vitamin K is a coenzyme for glutamate carboxylase which converts glutamate residues to ${\gamma}$-carboxyglutamate(Gla) residues. Gla residues have calcium binding ability and bound to hydroxyapatite crystals in bone. Vitamin K promotes the carboxylation of osteocalcin and matrix Gla-protein, vitamin K-dependent proteins and improves bone mineral density and bone mass. Vitamin K deficiency causes reductions in bone mineral density and increases the risk of osteoporotic bone fractures, resulting from undercarboxylated osteocalcin. This paper is to provide a brief information of vitamin K and its role in bone health.

Vitamin D, a free sunshine vitamin available for mankind from nature, is capable to avert many health-related critical circumstances. Vitamin D is no more regarded as a nutrient involved in bone metabolism alone. The presence of vitamin D receptor in a number of tissues implies that vitamin D has various physiological roles apart from calcium and phosphorus metabolism. Low serum vitamin D has been found to be associated with various types of metabolic illness such as obesity, diabetes mellitus, insulin resistance, cardiovascular diseases including hypertension. Various studies reported that vitamin D insufficiency or deficiency in linked with metabolic syndrome risk. This review focuses on various metabolic diseases and its relationship with serum vitamin D status.

Purpose: Neonatal late-onset hypocalcemia is defined as hypocalcemia developed after postnatal 3 days and associated with hypoparathyroidism, high phosphate diets and vitamin D deficiency. We experienced the increment of neonatal late onset hypocalcemia over 1 year. We tried to evaluate the relationship between late onset hypocalcemia and maternal hypovitaminosis D. Methods: The medical records in the neonates with late-onset hypocalcemia during January 2007 to July 2008 were retrospectively reviewed. Among those patients, 17 paired sera of mothers and neonates had collected. The levels of 25-OH vitamin D (25OHD) and intact parathyroid hormone (iPTH) were measured and were compared with neonate and the mother. Results: The mean gestational age was $38^{+1}$ weeks, and the mean body weight was 2,980 g. The onset time of hypocalcemia was 5.9 days of age. Most of them (88.2%) were feeding with formula and no one was only breast milk feeding. Of the 17 patients, 13 were born in spring or in winter. The median levels of calcium, phosphorus, alkaline phosphatase, iPTH and 25OHD were 7.0 mg/dL, 8.6 mg/dL, 191.0 U/L, 57.2 pg/mL and 24.0 ng/mL in neonates. The levels of 25OHD of 6 neonates were <20 ng/mL. A total of 16 mothers were considered vitamin D-deficient (<20 ng/mL), and vitamin D insufficient (20<25OHD<30 ng/mL). Conclusion: Neonatal late-onset hypocalcemia in our study seems to be influenced by maternal vitamin D deficiency and insufficiency. Sun tanning and vitamin D supplements from winter to spring would be helpful to prevent maternal vitamin D deficiency, one of the causes of neonatal late-onset hypocalcemia.

This study was conducted to evaluate nutrient intake, indices of anemia, serum lipids, and their correlations in 40 Korean female college students aged 21 to 25 years. Fasting blood samples were collected in October. 1997 Nutrient intake was investigated by 24-hour recall method for three days. Anthropometric measurements, blood pressure, iron status and serum lipids of the subjects were determined. The mean values for age. height, weight, BMI and blood pressure of the subjects were 22.1 years, 160.6cm, 54.4kg and 109.1/66.9mmHg, respectively. According to the body composition analysis, total body water, % body fat, lean body mass and WHR were 26.7L. 29.5%, 36.5kg and 0.8, respectively. Average daily intake of energy was 1,858.4kcal. Protein, phosphorus, vitamin B$_1$, vitamin B$_2$, niacin and vitamin C intakes were higher than the Korean recommended dietary allowence(RDA), whereas calcium, iron, vitamin A intakes were tower than that. Hemoglobin(Hb), hematocrit(Hct), serum iron(SI) and total iron binding capacity(TIBC) were measured and transferrin saturation (TS%) was calculated from serum. The mean values for Hb, Hct, SI, TIBC and TS were 13.6$\mu\textrm{g}$/㎗, 41.6%,97.8$\mu\textrm{g}$/㎗, 319.6$\mu\textrm{g}$/㎗ and 31.9%, respectively. The Prevalence rates of iron deficiency assessed by Hb and Hct were found to be 10% and 2.5%, respectively. However, when assessed with TIBC, the prevalence rate of iron deficiency was increased to 32.5%. The mean values for serum triglyceride(TG), total cholesterol(TC), HDL-Chol, LDL-Chol concentrations and atherogenic index(AI) were 154.7mg/㎗, 80.0mg/㎗, 47.4mg/㎗, 91.3mg/㎗ and 2.6, respectively. Correlations among indices of anemia. there were positive correlations between Hb and Hct, between SI and TS : negative correlations between TIBC and TS or SI. Correlations among serum lipids, there were positive correlations between TC and TG or LDL-cholesterol. Energy intakes were correlated positively with TIBC(p＜0.05), and vitamin C intakes negatively correlated with Hb(P＜0.05). And vitamin A intakes were negatively correlated with TG(p＜0.01). TC(p＜0.05) and LDL-Chol(p＜0.01). Hb negatively correlated with TG(P＜0.05). Body weights(p＜0.05), lean body mass(p＜0.05) and total body water(p＜0.01) werenegatively correlated with Hb. BMI and WHR correlated with TG and TC(p＜0.01). These results indicated that subjects with higher energy intake and overweight had a tendency to have iron deficiency. Increases in BMI and WHR were related to increases in serum lipids levels and decreases in TIBC. The results also showed that serum lipids were decreased when vitamin A and iron intakes were sufficient.

Growth and physiological disorders caused by abnormally low temperatures were evaluated in pepper, an important field crop in Korea. In addition, the effects of chemical treatment using glutamine was verified on minimizing the damages by low temperature. The growth of pepper plants in stem length and diameter was suppressed as the temperature decreased from $25^{\circ}C$, and the suppression level was the highest for plants grown for 90 days at $20^{\circ}C$. However, root growth was not affected by the different temperatures. The number of leaf and leaf area decreased at the temperatures below $25^{\circ}C$, an optimum temperature for growth. Fresh weight and dry weight decreased for plants grown at $20^{\circ}C$. Pepper fruit yield also decreased by 11% at $20^{\circ}C$ in comparison to $25^{\circ}C$. Falling blossom rate was different depending on the growth temperature, and the rate was 27.2% at $25^{\circ}C$, 35.2% at $22.5^{\circ}C$, and 41.0% at $20^{\circ}C$, indicating that falling blossom rate increased as temperature decreased. Different growth temperatures did not affected on the level of symptom of calcium deficiency and Phytopathora blight. Falling blossom was severe at abnormally low temperature of $20^{\circ}C$, but the treatment of glutamine reduced falling blossom rate and increased the yield by 7.0% as compared to control. The optimum concentration of glutamine treatment was 10 mg/L for yields.
