The purpose of this study was to investigate the convergence factors affecting disease management efforts of the middle-aged population who have comorbidities of all three metabolic diseases: type 2 diabetes, hypertension, and dyslipidemia. This study used raw data from the 2015 community health survey(CHS). A multiple hierarchical regression analysis was performed that the included variables explained 20.1% of the variance in weight-loss efforts, 6.8% of exercise efforts and 5.3% diet efforts respectively. This study revealed associations among gender, socioeconomic status, and behavioral habits of smoking and drinking with disease-management efforts. It is important to design a health service or supportive intervention with consideration of multiple factors for patients with multiple metabolic disease.

This study attempted to evaluate the effectiveness of function of Wax Ground for obesity and the related disease of adult people can be developed by the combination of the 17 food materials screened in this study. The experiments using Sprague-Dawley male rats show that seventeen kinds of food material inhibited the increase of body weight gain, energy intake, fat pads weight, liver triglycerides content, atherogenic index, and blood glucose concentration induced by cafeteria diet. Oral administration of wax gourd decreased most body weight gain, energy intake, fat pads weight, and blood glucose concentration. Liver triglycerides content was the lowest in the group administered mulberry stem extract and the group administered pine leaves showed the lowest atherogenic index. The combined administration of wax gourd, mulberry stem extract and pine leaves improved more the obesity and related symptoms than the individual administrations.

The objective of this study was to examine the impact of changes in maternal age and parity distribution on birth weight. The study population included 7,786 single live births in 1977 and 8,671 single live births in 1987 delivered at 9 medical facilities in Pusan. Data were obtained from the delivery record. The proportion of infants born to the mothers of 25-29 years increased from 56.475 in 1977 to 65.1% in 1987 and the proportion to the mothers of 30-34 years increased from 18.8% in 1977 to 21.6% in 1987. In the same period, the proportions of 1st and 2nd birth order were increased from 56.9% and 28.8% to 59.9% and 36.8%, respectively. The proportion of infants born to the age group of ${\leq}24\;and\;35{\leq}$ years were decreased in 1987. The proportion of births of the third or higher birth order was decreased from 14.2% in 1977 to 3.3% in 1987. Low birth weight (<2500gm) incidence rate was 5.3% in 1977 and it was decreased to 4.0% in 1987. It was estimated that changes in maternal age-parity distribution accounted for 10.7% of the decreased in low birth weight incidence rate. Rest of the change (89.3%) was attributed to the reduction of age-parity specific low birth weight incidence rate. Application of the direct adjustment method was considered to be an adequate tool for evaluating the impact of family planning on neonatal health.

The object of this study was to determine the difference of radiation effect in different fractional doses and to establish optimal fractionation schedule on the whole-abdominal X-ray irradiation. Total 160 mice were irradiated with 150 KVP, 15 mA orthovoltage x-ray machine and two different fractionation (100 cGy/Fr. and 200 cGy/Fr.) were used. Body weight, hemoglobin and WBC count with differential count were analyzed according to the same amount of total dose, same field size and two different fractionation schedules. The result of this study were summarized as follows: There was no significant difference in body weight and hemoglobin concentration by sex or fractional dose. Leukopenic change was prominent in the 3,000 cGy irradiation group and the proportion of decrease was remarkable in the 200 cGy/Fr, group than 100 cGy/Fr, group. Progressive decrease of lymphocyte count and reciprocal increase of neutrophil count were noted as dose increment. The effect of the fractional does on WBC count and proportion of lymphocyte were significant. This suggests that judicious selection of fractional dose may be important in clinical radiotherapeutic practice.

Spawning of matured olive flounder, Paralichthys olivaceus was accelerated by using single injection of human chorionic gonadotropin (HCG 1,000 IU/kg BW) or carp pituitary extract (CPE 10 mg/kg BW). The body weight of HCG or CPE treated group slightly improved with $5.6\pm0.4\%$ at 2 days after injection or $6.4\pm0.5\%$ at 3 days after injection, Number of eggs spawned increased in the fish treated with HCG or CPE. Surface floating rates of eggs spawned increased in the fish treated with HCG or CPE. Hatching rate also increased in experimental groups compared to the control. Especially superior quality of eggs were obtained 2 and 3 days after injection from HCG treated groups and 3 and 4 days after injection from CPE treated groups at $20^{\circ}$, respectively.

In this study, to evaluate the anti-obesity effects of mulberry leaf tea and its fermented product by Monascus pilosus, we investigated body and organ weight, blood and liver biomarkers in mice fed 1% tea infusions instead of water for 8 weeks. Mice were divided into three groups such as a normal control (NC), unfermented mulberry leaf tea infusion (UMI) and fermented mulberry leaf tea infusion (FMI). Although it is not significant, tea infusion groups showed reduction of body weight gains compared with NC group. Moreover, contents of LDL-cholesterol and lipid peroxide (LPO), altherogenic index, and xanthin oxidase (XO) activity were significantly decreased, and glutathione S-transferase (GST) activity was significantly elevated. The results from this study suggested that UMI and FMI may have an anti-obesity activity, upregulate antioxidant enzymes and reduce levels of oxidants related to liver damage.

The aim of this study was to achieve optimal portal phase while reducing contrast medium by applying weight-based dose protocol compared to standard fixed dose protocol to performing of pediatric abdominal CT examination. Discovery 750HD (General Electric Medical Systems, Milwaukee, USA) was used, and a total of 167 children consisting of 85 men and 82 women under the age of 18 were studied. The group in which the 300 mgI/ml(Xenetix, Guerbet, France) contrast medium was fixedly injected at twice body weight and the group injected with physiological saline while gradually decreasing the injection amount by 10% while applying the weight-based protocol were distinguished. Also, the CT number and SNR of abdominal organs were compared and evaluated while changing the scan delay time. Subjective image quality of enhancement and beam-hardening artifacts of around the heart was assessed with five-point criterion. The group adapted weight-based protocol with 20% reduction in contrast medium was most similar in contrast enhancement in the group with fixed injection at twice body weight. Furthermore, the group with a delay time of 20% had the highest contrast enhancement effect, and the difference in CT attenuation coefficient from the group scanned immediately after injection of the contrast media. Therefore, the appropriate delay time after injection of the contrast agent increased the contrast enhancement of the parenchymal organ. In addition, the weight-based injection protocol with normal saline reduced artifacts around the heart, and the effect of contrast enhancement could be maintained. In conclusion, it is possible to reduce dosage of contrast media through the application of weight-based injection protocols and appropriate latency, and to characterize optimal portal phase imaging on pediatric abdominal CT.

The effects of n 3 polyunsaturated fatty acid (PUFA) on protein and phospholipid con-tents, and cholesterol level were studied in rats fed with diets of different fat composition. Body weights of fish oil groups were decreased to $11.1\%\~14.4\%$ compared with lard group (control), and also $16.4\%\~23.3\%$ compared with corn oil group, respectively. Protein contents of $\omega3$ PUFA and sardine oil groups in liver were increased to $6.78\%\~8.51\%$ compared with control group, but were no significant difference in brain and serum. $\omega3$ PUFA and sardine oil slightly repressed the phospholipid in microsome of liver. Moreover they effectively reduced the serum cholesterol levels compared with control group.

In this study, we investigated the effect of seatangle drink and seatangle extract product on weight gain and serum and hepatic lipid composition in rats fed a hyperlipidemic diet. In the dietary hyperlipidemia induced rats, it was observed that serum triglyceride, phospholipid, total lipid, LDL-cholesterol level and atherosclerotic index were higher, while the HDL-cholesterol level was lower when compared to the normal group. Total hepatic lipid and cholesterol content of the dietary hyperlipidemia induced rats was conspicuously decreased by seatangle drink and seatangle extract product treatment. Especially, triglyceride content was decreased to 30% by seatangle drink treatment, and 45% by seatangle extract product treatment.

Purpose : Although neonatal pulmonary hemorrhage is rare, it is associated with high mortality. We aimed to evaluate the risk factors associated with pulmonary hemorrhage in preterm infants and to describe the clinical course, including neonatal morbidity, of infants who developed pulmonary hemorrhage. Methods : We performed a retrospective case-control study of 117 newborn infants aged less than 37 gestational weeks admitted to the neonatal intensive care unit of Daegu Fatima Hospital between January 1995 and December 2008. Control group infants without pulmonary hemorrhage were matched according to the gestational age, duration of mechanical ventilation, and birth weight range (${\leq}100g$). Pulmonary hemorrhage was defined as the presence of hemorrhagic fluid in the trachea and severe respiratory decompensation. Results : Pulmonary hemorrhage occurred in 17 cases of very low birth weight infants (VLBW; birth weight < 1,500 g; median age, 3 days) and 22 cases of low birth weight infants (LBW; $1,500g{\leq}$ birth weight < 2,500 g; median age, 1 day). Antenatal maternal glucocorticoid treatment significantly reduced the incidence of pulmonary hemorrhage in VLBW infants. Low APGAR score (${\leq}3$ at 1 min) and acidosis at birth were associated with significantly high incidence of pulmonary hemorrhage in LBW infants. Conclusion : Antecedent factors and timing of pulmonary hemorrhage of LBW infants were different from those of VLBW infants. The mortality rates of VLBW and LBW infants were 88.2% and 45.5%, respectively. Pulmonary hemorrhage was the principal cause of death in 66.6% VLBW infants and 40.0% LBW infants.
