Continuous monitoring of dam performance is essential to earth and rockfill dams safety because it has to be guaranteed for safety during construction period of course and from initial impounding to a long term maintenance period of dam. Among the 31 dams managed by Kwater at present, the proportion of dams being over 20 years after completion of construction is 42% and it is estimated that the loss rate of monitoring devices will be increase as times. Monitoring devices would be impossible to repair since those are mostly installed in the dam body and foundation. If repairing of monitoring devices is possible, the expenditure will be expensive. Therefore reasonable decision making for abandonment, repair and alternation for loss of monitoring devices would be needed through the establishment of key instrument for earth and rockfill dam safety. In this study the process of monitoring for safety were modeled by failure modes of dams, adverse conditions related to failure mode, indicators of adverse condition and monitoring devices The relationship between failure mode and monitoring devices were systematically analyzed and established and evaluation technique for qualifying the importance of monitoring devices were presented.

Radon and radon progeny being natural radioactive pollutants, seriously affect the health of uranium miners. Radon reduction by ventilation is an essential means to improve the working environment. Firstly, the relational model is built between the radon exhalation rate of the loose body and the ventilation parameters in the stope with radon percolation-diffusion migration dynamics. Secondly, the model parameters of radon exhalation dynamics are uncertain and described by triangular membership functions. The objective functions of the left and right equations of the radon exhalation model are constructed according to different possibility levels, and their extreme value intervals are obtained by the immune particle swarm optimization algorithm (IPSO). The fuzzy target and fuzzy constraint models of radon exhalation are constructed, respectively. Lastly, the fuzzy aggregation function is reconstructed according to the importance of the fuzzy target and fuzzy constraint models. The optimal control decision with different possibility levels and importance can be obtained using the swarm intelligence algorithm. The case study indicates that the fuzzy aggregation function of radon exhalation has an upward trend with the increase of the cut set, and fuzzy optimization provides the optimal decision-making database of radon treatment and prevention under different decision-making criteria.

Objectives: This study was performed to investigate the effects of overestimation of their own body shape on weight control behaviors, mental condition, physical activity, dietary behavior, health-related quality of life, and nutritional status among young Korean females. Methods: A total of 1,514 women aged 20-39 years who are not pregnant and lactating among those who participated in the Fifth Korea National Health and Nutrition Examination Survey (2010~2011), were analyzed and grouped into underestimation (n=120), normal estimation (NE, n=840), and overestimation (OE, n=554), based on their body perception compared to actual percent ideal body weights. Variables were compared between OE group and NE group. Results: The subjects in OE group were significantly younger (29.5 vs. 30.5 years, respectively p < 0.05) and had lower body mass index (20.9 vs. 22.2 respectively, p < 0.01), health-related quality of life measured by EQ-5D (EuroQol-5 Dimension)(0.97 vs. 0.98 respectively, p < 0.05), nutrition adequacy ratio (NAR) of protein (0.91 vs. 0.93 respectively, p < 0.05), phosphorous (0.93 vs. 0.96 respectively, p < 0.05), and iron (0.70 vs. 0.75 respectively, p < 0.01), and index of nutrition quality (INQ) of iron (0.84 vs. 0.89 respectively, p < 0.05) compared to those in the NE group. The results of logistic regression showed that unmarried status (OR 1.32; 1.01~1.72) and severely underweight/underweight status (OR 1.94; 1.01~3.75)/(OR 1.81; 1.34~2.45) were significantly related to the probability of overestimation by the subjects. Significantly more women in OE group practiced fasting, skipping meals, and taking prescribed pills to lose body weights and had skipped breakfast compared to those in the NE group. Conclusions: The results of this study suggested that the Korean young women's distorted perception of own body shape may be associated with undesirable weight control behavior, low quality of life, and lower nutritional status. Therefore, nutrition education for this group should include information on correct body shape perception and its importance.

Objectives: The intention of this study was to find out the impact of mother's body mass index, eating habits, nutrition status and sociodemographic factors on the body mass index of the children. Methods: The study used original data of Korea National Health and Nutrition Examination Survey (2010-2011) and had 957 children in the ages of 1-5 years and 957 mothers of these children, a total 1,914 as subjects. The weights (body mass indexes) of the children, subjects under 5th percentile were classified into a underweight group, 5~84th percentile into a normal weight group, 85-94th percentile into an overweight group and more than 95th percentile into an obesity group based on the 2007 Korean children and adolescents growth chart. Results: We observed that when the body mass index of a mother increased by 1, the possibility that her child would belong to the overweight group increased by 6.5% (95% confidence interval: 1.01~1.13), and the possibility that the child would belong to the obesity group increased by 95% (confidence interval: 1.01~1.18). With regard to the number of deficient nutrients which were ingested according to estimated average requirements (EAR) amid nutrients ingested by the mother increased by 1, the possibility that the child would belong to the obesity group increased by 16.6% (95% confidence interval: 1.01~1.35). In case the birth weight of child increased by 1kg, the odds ratio that the child would belong to the obesity group was 2.022 (95% confidence interval: 1.08~3.77). Conclusions: We conclude that the body mass index, eating habits and nutrition status of the mother had significant effects on the body mass index of the child. Therefore, it is critical to recognize the importance of this observation and provide practical training for eating habits and nutrient intakes in order to achieve healthy growth and prevention of obesity among children.

In the case of a severe accident of a nuclear power plant, the whole body dose and the relative importance of the radionuclides during the lifetime of an exposed person were estimated for each exposure pathway with distances from the release point. The external exposure pathways due to immersion of radioactive cloud and deposition of radioactive materials on the ground, and the internal exposure pathways due to inhalation and ingestion of contaminated foodstuffs were considered. The effects due to the ingestion of contaminated foodstuffs were estimated considering the variation of radioactive concentration in the foodstuffs according to deposition time and elapsed time after deposition using a dynamic ingestion pathway model applicable to Korean environment, named 'KORFOOD'. As the results up to 80 km from the release point, the effects due to ingestion of contaminated foodstuffs showed the highest contribution to total exposure dose. The contribution of I isotopes was the highest in the case of the external dose due to immersion of radioactive cloud and internal dose due to inhalation. The contribution of Cs isotopes was highest in the case of the external dose due to deposition of radioactive materials on the ground. In the case of the internal dose due to ingestion of contaminated foodstuffs, Cs deposition in summer and Sr deposition in winter, respectively, were the most dominant radionuclide to whole body.

The results of immune response and antiallergic reaction were as follows. 1. Hemagglutinin titer and hemolysin titer were increased in case of AMR, AR, SNH. But the results were not recognized as having significance. 2. PFC was increased in case of AMR, AR. But the results were not recognized as having significance. 3. RFC was increased in all groups, and the results in the AR, SNH were significant. 4. In experimentation of phagocytic activity in peritoneal exudate cells, AR and SNH showed significant increase. In spleen cells AR and SNH showed significant increase. In monolymphocytus cells AMR, AR and SNH were increased, but result of AMR was of no significance. 5. I examined promotion on spleen cells transformation. As these results, AMR showed increase in $50{\mu}g/m{\ell}$, $5000{\mu}g/m{\ell}$ in comparison with control group. And in $500{\mu}g/m{\ell}$ AMR showed increase in case of 24 hours, 72 hours incubation, but showed decrease in case of 48 hours incubation. AR showed increase in all. In $50{\mu}g/m{\ell}$ SNH showed increase in comparison with control group. And in $500{\mu}g/m{\ell}$, $5000{\mu}g/m{\ell}$ SNH showed increase in case of 24 hours, 48 hours incubation, but showed decrease in case of 72 hours incubation. 6. I examined proliferation of spleen cells. As these results AMR and SNH showed the highest increase in $50{\mu}g/m{\ell}$, but showed the lowest increase in $5000{\mu}g/m{\ell}$. AR showed the highest increase in $500{\mu}g/m{\ell}$, but this result was the almost same in $50{\mu}g/m{\ell}$, $5000{\mu}g/m{\ell}$. And AMR, AR, SNH showed higher activity in Lipopolysaccharide than Concanavalin A. 7. In all groups results of PCA were decreased in 2 week. In 4 week AR and SNH showed decrease, but AMR didn't show change. In 6 week AR and SNH showed decrease, but on the contrary AMR showed increase. 8. In experimentation on histamine contents, AMR showed significant increase at first agent contact. And AR, SNH showed decrease at first agent contact, but these results were of no importance. At second agent contact AMR showed decrease, but was of no importance. AR, SNH showed significant decrease. At third agent contact, AMR showed significant increase. AR, SNH showed decrease, but these results were of no importance. From above these results, AR and SNH showed good effects on immunoreaction. And all the herb medicines in this examination showed good effects in promotion on spleen cells transformation and proliferation of spleen cells, especially activated B-cells. AR, SNH showed good effects on anti-allergic reaction, but AMR was almost inefficient. Accordingly I think that AR shall be used in disease bringing about a lowering of immunity, that is, AR shall be used in strengthening the body resistance. And I think that SNH shall be used in eliminating pathogenic factors with strengthening the body resistance. It is necessary to a deep study in future.

This study researches the attitudes of nursing students toward induced abortion. It aims to Identify the structure of subjectivity of nursing students toward induced abortion. As the research method, Q-statements were collected preliminary to the study through in-depth group talking, case study and literature review. For the study, 28 Q-statements were selected. There were 40 students as subjects for the research. The 40 students sorted the 28 statements using the principle of Forced Normal Distribution. The results of the study were as follows : Three attitude types toward induced abortion were derived from Q-Factor analysis by using PC Quanal Program. The first type is called qualified deontology type. The second type is called rational utility type. The third type is called self-centered utility type. 1) Qualified deontology type emphasizes the importance of respect for life. Induced abortion is acceptable within just limit circumstances. 2) Rational utility type has more tolerance limits. There are rationale for induced abortion. Thls type hates becoming the target of criticism because they are single mothers, were rape or had a deformed baby. 3) Self-centered utility type believe that the most important in the world is one's self. This type emphasizes the importance of women's autonomy. And then the woman should be able to decide about abortion, because it is her body, it is her choice. The result of the study suggests that nursing education need more ethical teaching of the importance of human life. Be cause the fundmental concept of nursing is in the preservation of human life and in the respect for life, dignity and the rights of man. Nursing ethics is a essential for nurses.

Although the human body is a biological subject with definite and distinctive physical features, its actualization and perception differs among societies. The aesthetics of the human body are based on diverse cultural perceptions that must be considered prior to design development. This study establishes the foundations of newly adopted concepts of beauty that are presumed to have been established in the first half of the twentieth century that continue to affect our mindset even now. The research includes human figures in the articles of women's magazines and cosmetic advertisements in the early $20^{th}$ century. The results are as follows: First, the change of perception in the human body: Instead of being a subject of preservation, the body has become a subject of sculpture with emphasis on health in the 1920's and on beauty in the 1930's. The recognition of the importance of the body has created intensive attention on physical training and an increased sense of hygiene. The body exposed to the public perceives itself through the eyes of others that alter one's own perception of oneself as well as become a target of evaluation. There is an additional emphasis on the exotic eroticism of a passive subordinate. Western culture became the standard for modernization along with the dissociation of traditional standards and values. Through the effect of education and western thinking, the awareness of women's rights and self-appreciation was developed. Second, ideal beauty can be summarized as follows: Unprocessed natural beauty was extolled as ideal in the 1920's, but the 1930's, it highlighted big eyes and an aquiline nose that are the characteristics of western women. Taking care of one's appearance was recognized as an important value for every social class. Cosmetics and skin care treatments promised soft and white skin. In contrast to western cosmetics, dark and shiny hair was highly favored. Exercising and traveling, differing seasonal and regional skin treatments were also widely accepted. In its initial stages, the research had originally assumed that the beginning of the twentieth century would be a time in which traditional concepts of beauty and new, westernized aesthetics coexisted. However, as the research progressed, it was clear that the idea of beauty had already adopted occidental ideals by that time. Thus, it seems necessary to continue the study on the shifting paradigms of beauty that must have occurred in the nineteenth and late twentieth century.

The physical fitness of the cadets of the Air Force Academy, which will protect the airspace of the Republic of Korea, is of paramount importance to fulfill the given mission. Therefore, the purpose of this study was to confirm the characteristics of body composition and physical fitness of female cadets of Air Force Academy and to verify their relationship with physical fitness according to body fat % level of total female cadets. To achieve the purpose of the study, 50 female cadets of the Korea Air Force Academy (1grade 13, 2grade 18, 3grade 9, 4grade 10) were measured in body composition (skeletal strength, body fat mass, body mass index, body fat %, abdominal obesity rate, basal metabolic rate) and physical fitness (muscle strength, muscular endurance, power, agility, flexibility and balance). One way ANOVA was performed for data processing to identify body composition and physical fitness characteristics by grade and to identify differences in physical fitness according to body fat rate levels. According to the study, the 1 grade was lower in body fat mass and body fat % among female cadets, the 2 grade was lower than the 3 and 4 grades, and the body mass index was lower than the third and fourth grades. Also, there was no difference in the physical fitness of the rest of the year. The intergroup physical fitness according to the body fat rate was higher than that of those with less than 20 percent of net worth and 25 percent to less than 25.1 percent to 30 percent, while those with less than 20 percent balance were higher than those with less than 25.1 to 30 percent. The results of this study showed differences in body composition by grade in female cadets, especially in power and balance according to body fat %. Therefore, female cadets of the Air Force Academy need to manage body fat to have the power and balance capability related to the airborne mission environment.
