This study was designed to investigate the relationship between body mass index (BMI) and dietary intake, and the relationship between BMI and plasma lipid levels in Korean adults. This study was conducted from January 1 to December 31 of 1997. It consisted of 3781 subjects (men 2402, women : 1379) with the majority between the ages of 40 and 59. The dietary assessment was based upon a twenty-four-hour food record. Subjects were classified into one of four reference BMI groups : underweight ($\leq 20 kg/m^2$), normal (20.1-25.0 kg/$m^2$), overweight (25.1-30.0 kg/$m^2$), and obese (>30 kg/$m^2$). The biochemical assessment included measurements of plasma total cholesterol (TC), HDL-cholesterol (HDL-C), LDL-cholesterol (LDL-C), triglyceride (TG), lipoprotein (a), and plasminogen activator inhibitor-1 (PAI-1). The BMI study showed that 60.5% of the men measured were normal and 32.6% of the men were overweight and/or obese subjects. Sixty-four percent of the women were normal and 20.3% of the women measured were overweight and/o. obese subjects. With respect to the daily energy intake of the men and women subjects, the levels of daily energy intake appeared to increase as values of BMI increased. Men of the overweight group had significantly higher protein, fat and cholesterol intake than those of the normal or the underweight groups. The alcohol intake of the men in the overweight group was also significantly higher than that of the men in the underweight group. With respect to percent energy intake of macronutrients, there was no significant difference between the four BMI groups and percent energy intake for all the subjects in the study. The ratio of percent energy intake of carbohydrates : protein : fat : alcohol of the normal women group was 62 : 17 : 20 : 1, respectively. Women apparently had a higher intake of carbohydrates than men (52 : 17 : 19 : 10). With respect to the levels of plasma TC, LDL-C, TG, and HDL-C, the levels of plasma TC, LDL-C and TC appeared to increase as the values of BMI increased, while the level of HDL-C appeared to decrease as values of BMI increased. Levels of lipoprotein (a) appeared to be inversely related to the values of BMI, and levels of PAI-1 appeared to increase as values of BMI increased. The results of this study demonstrate that there is a relationship between dietary intake and BMI, and that there is a relationship between BMI and blood lipids levels.

Indeterminacy maintains that the simultaneous measurement of object location and speed is theoretically impossible. This study present indeterminacy as a theoretic tool to interpret a variety of expression characteristics that seem disorderly in recent fashion illustrations; in addition, it analyzes the characteristics and meaning of indeterminacy as expressed in fashion illustrations. This study reviews concepts and related theories on indeterminacy to examine characteristics of indeterminacy expressed in the arts and fashion; subsequently, indeterminacy characteristics found in fashion illustrations are analyzed. In expressing the fashion figure, indeterminacy finds expression in a distorted figure transformations that include a hybridized combination of heterogeneous forms that dismantle and reconstruct the human body. The hybridized body of combined machines, animals and plants indicates an indeterminate body endlessly transforming itself. Indeterminate space expression finds expression in space expression by projection with the overlapping and juxtaposition of irrelevant constituent elements as well as a space expression from the insertion of unexpected images. An unclarified inconclusive open space provides space with fluidity, causes space expansion and conveys inconclusive meaning. Indeterminate expressions found in fashion illustrations reveal the ambiguity and complexity of a post-modern society with polysemous aesthetic values and the expanded visual concepts of fashion illustrations.

The acute and subacute toxicity of water soluble dimethyl dimethoxy biphenylate derivative (new DDB), hepatitis therapeutics, were investigated in SD rats. In the acute toxicity study, body weights and clinical signs were observed for 7 days after the intravenous injection of new DDB at doses of 140, 182, 236, 307 and 400 mg/kg(r=1.3). Death. Severe convulsion, tremor and decrease motor activity were observed in almost treated groups (except the 140 mg/kg treated group). Changes of body weight in treated groups were not significantly different from control group. Autopsy of survived animals revealed no abnormal gross findings related to new DDB. As a results, the $LD_{50}$ values of new DDB were 244.1 mg/kg for male and 232.5 mg/kg for female. In subacute toxicity study, body weights and clinical signs were observed after intravenous injection of new DDB at doses of 57, 75 and 100 mg/kg/day for 28 days. Death, decrease motor activity and tremor were observed above 75 mg/kg treated groups. Statistically significant changes were observed in hematological and biochemical parameters of new DDB-treated groups; however, these changes were within normal range and had no relationship with dosage. Several abnormal findings were observed in microscopic examination of tissue; however, these findings were not caused by new DDB but environmental factor. The no toxic dose level of new DDB were estimated to be 57 mg/kg/day in this study.

Detrimental effects of inbreeding have been studied by many researchers for a long time. However, only a few studies have shown the occurrence of inbreeding depression due to evolutionary changes as a purging process. In this study, two different populations (inbreeding and outbreeding) of Drosophila melanogaster were compared to assess inbreeding effects on artificial population bottlenecks. For inbreeding conditions, a couple of D. melanogaster (one virgin and one male) were selected from an inbred population and cultured in a vial. For outbreeding conditions, a couple of D. melanogaster were selected from different populations and cultured in a vial. There were significant differences in body lengths of adults, but not in other parameters such as the total number of adults, the rate of survival, and the rate of wing mutants. The mean body length of adults of outbreeding populations was longer than that of inbreeding populations in the first generation (G1; P = 0.004), but not in the second generation (G2; P = 0.066). Although the other three parameters (total number of adults, rate of survival, and rate of wing mutants) showed differences in their mean values between inbreeding and outbreeding populations, these differences were not statistically significant. This might be due to genetic purging. This study demonstrated one additional experimental case related to inbreeding depression in artificial bottlenecked populations. Further studies are necessary to confirm the clear interaction between inbreeding depression and genetic purging using more generations and replicates (or samples) of D. melanogaster.

Purpose: The purpose of this study was to analyze the experiences and perceptions of nursing students related to their cadaver practice through an integrative review. Methods: An integrative review was conducted using Whittemore and Knafl's framework published in 2005. The key words, "nursing students & cadaver" and "nursing students & anatomy" were used to search peer-reviewed publications in six databases. Among 373 searched articles, 15 articles were selected after excluding articles that did not meet the inclusion criteria. The literature quality was moderate (levels C and B). Results: The results from the 15 selected studies were integrated and classified into seven themes: "anxiety and discomfort," "gratitude and respect for donors," "dignity of the human body and life," "acceptance of death," "getting closer to the nursing profession," "enhanced understanding and memory of the human body" and "enhancement of learning motivation." Conclusion: In conclusion, cadaver practice provided an opportunity to form values about the dignity of life and death, helped nursing students understand the human body, and motivated them to approach the profession of nursing. It is suggested to develop integrated cadaver practice programs that incorporate bioethics, spiritual nursing, and the vocation of the nursing profession.

Two experiments were conducted to evaluate the efficacy of dietary FERMKIT, a commercial toxin binder consisting of probiotic-fermented natural product containing chitin, chitosan and chitosan oligosaccharides ($FERMKITO^{(R)}$, EASY-BIO SYSTEM, Inc., Korea), in binding aflatoxin (AF) and zearalenone (ZEN) and ameliorating their mycotoxicity in meat type ducks. FERMKIT was supplemented to AF contaminated diets (at 120 ppb) at either 0.3 or 0.6% in experiment 1 and to ZEN contaminated diets (at 150 ppb) at 0.6% in experiment 2. In experiment 1 body weight gains were reduced by 37% and mortality was increased by 18% in ducks fed diet contaminated with AF at 120 ppb compared to ducks fed control diet (<10 ppb AF) for the 4-wk experimental period. However, dietary FERMKIT supplementation effectively alleviated overall toxicity induced by AF. The significant treatment-related changes in feather growth, web-toe hemorrhage, leg deformity, liver paleness, organ weights, hematological values and serum biochemical values, as compared to the control, were observed. The FERMKIT supplementation significantly diminished the adverse effects of AF and restored all the parameters measured back (<0.05) toward the control values. These findings indicated that FERMKIT, when added at the levels of 0.3 or 0.6% in the 120 ppb AF diets, could modulate the toxicity of AF with percentage sorption capacity of 52.70% at the level 0.3% and 79.85% at the level 0.6% of the diets (experiment 1). In experiment 2, FERMKIT, when added at 0.6% to the 150 ppb ZEN diets for the 4-wk experimental period, diminished the toxicity as shown by body weight gain, weights of testicles, oviducts, Bursa of Fabricius and cloaca eversion score as compared with the controls (<10 ppb ZEN) and 150 ppb ZEN diet with no added FERMKIT. The findings indicated that FERMKIT could be protective against the effects of ZEN in young growing ducks with percentage sorption capacity of 67.11% as evaluated from toxicity index parameter measured when added at 0.6% of the diets containing 150 ppb ZEN.

Vitamin K has been suggested to plays a role in bone metabolism. The objective of this study was to determine whether vitamin K2 supplementation is related to bone mineral density, bone formation markers, and bone resorption in ovariectomized (OVX) rats. Forty Sprague-Dawley female rats (body weight, $200{\pm}10$ g) were divided into four groups: a sham group fed a control diet, a sham group fed a vitamin K2 supplemented diet, OVX fed a control diet, and OVX fed a vitamin $K_2$ supplemented diet (3.5 mg vitamin $K_2$/kg diet). All rats were fed the experimental diets for 6 weeks, and deionized water was provided ad libitum. Serum alkaline phosphatase activity (ALP), osteocalcin, and urinary deoxypyridinoline crosslink values were measured as markers of bone formation and resorption. Bone mineral density (BMD) and bone mineral content were measured in the spine and femur using PIXImus (GE Lunar Co., Madison, WI, USA). No significant differences in body weight gain, food intake, or food efficiency ratio were observed between the control and experimental groups. Serum ALP, osteocalcin, and urinary crosslink values were not significantly different between the vitamin $K_2$ supplemented groups. No significant differences were observed for any of the variables in the sham group. Spine BMD values were significantly lower in the OVX than those in the sham groups. Spine and femur BMD per weight of vitamin $K_2$ tended to be higher than the control diet group within the OVX group, but no significant differences were observed. In conclusion, dietary vitamin $K_2$ supplementation may have a beneficial effect on spine and femur BMD in OVX rats. Further research is needed to understand the potential benefits of vitamin $K_2$ on bone loss in OVX rats.

The present study was carried out to investigate the effect of test day milk yield, test day evening milk yield, parity, stage of lactation and body weight on milk urea and milk protein concentration. A total of 319 milk samples was collected from buffaloes over four month's period and subjected to urea and protein analysis. Milk urea concentration (mg/dl) was significantly (p<0.01) increased with increasing test day milk yield. The lowest value ($57.03{\pm}1.13$) was observed in the milk yield group ${\leq}4.5kg/day$ and the highest value ($64.15{\pm}1.13$) in the group 7.7-10.7 kg/day. However, test day evening milk yield had no significant effect on milk urea concentration. Milk protein did not vary significantly with the test day milk yield as well as test day evening milk yield. A clear decreasing trend of milk urea concentration (mg/dl) was found with the increasing parity. The highest MU concentration ($64.03{\pm}1.14$) was found in the first parity and the lowest ($55.67{\pm}1.22$) was found in the sixth and above parity. Whereas, stage of lactation had no effect on milk urea concentration. Moreover, parity and stage of lactation did not have any significant effect on milk protein concentration. Body weight (kg) was also found negatively (p<0.05) related with urea content (mg/dl) in milk. The highest mean MU concentration ($64.34{\pm}0.88$) was found when body weight was between 532 and 598 kg and lower mean values ($59.24{\pm}0.94$ and $59.33{\pm}1.23$) were observed in 599 to 665 kg and ${\geq}666kg$ group. Body weight also had significant (p<0.05) effect on milk protein content. The highest milk protein content (%) was found in ${\geq}666kg$ group and the lowest in <531 kg group. In conclusion, for proper interpretation of milk urea values to monitor protein nutrition status of the buffaloes parity, milk yield and body weight should be considered.

In this study, we measured body mass index, visceral fat ratio and 6 parts of body, neck circumference, circumference of upper arm, chest circumference, abdomen circumference, hip circumference, and thigh circumference by bioimpedence analysis system, after taking Gyeongshingangjeehwan16 (GGEx16) in five months except the first period before taking GGEx16 on 49 women who are obesity or high-level obesity. In order to examine the significance test for the effect of obesity improvement of GGEx16, we practices repeated measure ANOVA with values of measurement variables in 6 monthly times. As a result of all measurement variables, there were significant difference (P-value=0.001). Therefore, we can say that GGEx16 is effective about obesity improvement. As it dramatically decreased between second measure period and first measure period for all measure variables, we can see that there were the most effect of GGEx16 in the first time after taking GGEx16. It is known that a important measurement variable to have a effect for obesity improvement about two variable which are body mass index and visceral fat ratio is waist circumference through correlation analysis. The result of whether there are differences to effect of obesity improvement for GGEx16 around the climacteric, there were significant difference for the effect of obesity improvement for GGEx16 around the climacteric about all parts of body (P-value=0.001). There were also powerfully difference in effect of obesity improvement for GGEx16 around the climacteric about all parts of body (P-value=0.001). Especially, the climacteric before is more effective than the climacteric after in the aspect of the effect of GGEx16.
