This study was conducted to provide basic data for prevention of osteoporosis by examining the factors affecting bone mineral density in pregnant mothers. This investigation was a descriptive research study that analyzed a total of 137 medical records. Differences in T-score between general and obstetric characteristics were assessed by independent t-tests and one way ANOVA followed by Scheffe's post-hoc test. The mean age of the subjects was 32.4 years and the mean T-score was 0.34. The BMI measured at 4 weeks after delivery was significantly higher in the underweight group than in the normal group and the overweight group (F=11.935, p<.001). The BMD was significantly higher in subjects with sufficient vitamin D than in subjects with insufficient vitamin D, in subjects with insufficient vitamin D than in subjects with deficiency vitamin D (F=4.906, P=0.009). BMD was significantly higher in cases without experience of abortion than those with more than one experience of abortion (t=4.264, p<.001), and the normal delivery was significantly higher than that of cesarean section (t= 2.019, p=.046). Based on the results of this study, it is necessary to actively prevent the factors affecting BMD during pregnancy and delivery. The findings presented herein can be used as basic data for the management of osteoporosis.

A number of small and medium design companies in Korea are making efforts to develop distinguished products with an aim to survive and prosper. However, it is quite difficult to succeed due to insufficient experience in product planning and the challenges in applying known methodologies, which are based on a large amount of data presented as best practices in designing process, in the actual small and medium enterprise operations. To this end, this study suggested the usefulness of the user participation process as the methodology for small and medium design companies and chose the user FGD method implemented by Company P which is a small design company as an empirical case study. The following are the processes used in the case study; First, the problems of existing baby bath were derived through user FGD. Second, opinions were collected from various classes of users through in-depth interviews. Third, the ideas derived were analyzed with the KJ method and grouped based on similar elements, through which six design directions and detailed design concepts covering size, material, safety, purchase factors of existing product, direction of improvement, additional elements were derived. Through the case study, this study verified that the FGD method of Company P could improve the practical verification, integration and promptness of the product planning process in small and medium enterprises. This is valuable as a realistic process that small and medium enterprises with limited capital and manpower may adopt.

TV Broadcasting is an undeniable cultural medium. TV Broadcasting Station needs a long-term perspective that suits cultural media and an aggressive cultural and artistic program development strategy that matches rapidly changing culture and technology. Of course, production staff should be composed of experts in the field as well as cultural artists. This paper is researching the promotion strategy of TV Arts programs by substituting the three keywords - the U.S., the public broadcasting station(TV) and Arts programs. And through case studies and analyses of PBS TV's "Art in the 21st Century" series, the way the public TV broadcasting station shares cultural arts with viewers is extracted. It raises the question of how the U.S. TV public broadcaster's cultural and artistic programs are different from South KOREA's. Through the above research, let's find a clue to the future direction of how the new media, now represented as Korea's blacklist, should recognize, foster, educate and strategize Fine Arts.

This study was conducted to investigate the possibility of spontaneous ignition in Butadiene popcorn polymer, which is used as raw material and product in a chemical plant. A component analysis, thermogravimetric analysis, thermal stability analysis, spontaneous ignition point measurement and accelerated velocity calorimetric analysis were performed. As a result of analysis, various kinds of flammable components were measured and thermogravimetric analysis showed a weight loss of 95.6% in air and 89.2% in nitrogen. As a result of the thermal stability analysis, heat generation started at $88^{\circ}C$ in the air atmosphere, and the heat generation rate increased sharply in the vicinity of the natural ignition point ($220^{\circ}C$). The heat generation started at about $70^{\circ}C$ in nitrogen atmosphere, and the two exothermic peak values were observed up to $450^{\circ}C$. As a result of accelerated rate calorimetry, there was no exothermic phenomenon, and the lowest ignition temperature was $211.7^{\circ}C$ as a result of analysis of natural ignition point. Based on the results obtained from the thermal stability evaluation, it is considered that the possibility of inducing the thermal deformation of the column by the heat of reaction is sufficient.

The purposes of this study was to confirm the current issues of workforce policy of dental auxiliary personnel in Korea. The literature review and data collection were conducted in terms of the auxiliary personnel supply, regional distribution, legal works, working environment. Despite the rapid increase in the number of dental hygienists, the number of active dental hygienists is less than half of the total, and the dental clinics still experience the shortage. Considering the dental hygienist's work, the available dental auxiliary personnel for the dental assistance is limited. The proportion of dental hygienists is concentrated in large cities, and the ratio of dental clinics composed of only dental hygienists is high. Thus, it is essential to look for a plan to solve the disparity. The criterion for judging the legality of the works is ambiguous because a large portion of dental hygienist's work is not specified in the Medical Technicians Act. The job life is also shortened, and occupational profession and satisfaction are lowered. Thus, job burnout is accelerating. The difference between the legal works and the practiced works of dental hygienist and the conflict between the personnel might be due to the lack of utilization plans for the dental personnel at the government level. Therefore, the government should establish the roles of dental hygienist in accordance with the demands of the dental health service, institutionalize the necessary policies accordingly, and make efforts to establish plans to improve the relevant laws and utilize the manpower appropriately.

The Empathy for Dementia using Virtual Reality (EDuVR) system, developed by the Jeju Provincial Dementia Center, is a 3D video system capturing the experience of dementia in a first-person perspective using 360 degree vritual reality (VR) technology. It was developed to create a greater understanding of dementia and to help people empathize with individuals with dementia through an immersive VR experience. The EDuVR shows how a dementia patient has impairments in memory, orientation, language, judgment and problem solving, as well as problems with activities of daily living. The present study reported the effectiveness of the EDuVR experience in changing public awareness of, and attitude toward, dementia. Sixty-six participants were assigned to the EDuVR (n = 34) or the conventional education (n = 32) groups, and two types of questionnaires - attitude and awareness questionnaires - were administered to the subjects before and after the EDuVR experience or education. The simulator sickness and presence questionnaires were administered to the EDuVR group to assess cybersickness and presence of the VR experience. As a results, the attitude and awareness toward dementia patients changed positively in both the EDuVR and the conventional education groups, and these changes did not differ between two groups. Only one person reported a significant level of cybersicness after experiencing the EDuVR system. These results suggest that the EDuVR enhances the level of understanding and empathy for dementia and would be a useful tool for improving awareness in the general public.

In the early 2000s, the Korean government first attempted to acquire nuclear-powered submarines as strategic assets. Acquisition of nuclear-powered submarines must overcome the challenges of the initial costs and operating costs of trillions of US dollars per ship, must be agreed to by the international community (including neighboring countries) and in a national consensus, and must have an established technical infrastructure (including manpower). The US navy has been working with governments that want to acquire nuclear propulsion warships since the 1950s, and in 1982, they enacted an executive order called the United States Naval Nuclear Propulsion Program to consolidate efforts and prepare for the future, which sets out the organizational structure, authority, and responsibilities of US governmental management, and integrates national efforts. This paper is to gain valuable wisdom from the U.S. Naval Nuclear Propulsion Program by analyzing all of its histories and contributions, thereby providing valuable lessons for a future program in Korea. It might not be possible to follow the U.S.A. one-on-one because of the scale of national and military forces, but at least we can avoid time and effort spent on trial and error.
