Objectives: This study was designed to understand the association between sociodemographic characteristics, health behaviors and channels retrieved for health information. Methods: Questionnaire survey was performed from April 2007 to May 2007 through household visiting. Sample was selected according to gender, household income, and residence district. We got 1,009 respondents and subgroups were as follows; 508 people had health insurance, 250 people were medical indigent group, and 251 people were medicaid beneficiaries. Results: People seemed to be separated into subgroups by channels used for health information. One was active and the other was passive group. Characteristics of passive group were older age, worker or inoccupation, less income, subjective poverty, lower education, loss of spouse, medical indigent or medicaid group. They usually got health information through mass media like TV and radio or medical professionals. Characteristics of active group were younger age, professional, more income, subjective affluence, higher education, single or married, and member of health insurance. They mainly got health information through printed media like newspaper or the Internet. Conclusion: We suggest to provide health information through various channels customed to individual needs and literacy. Public health stakeholders seems better to focus on people with low education, insufficient health literacy, poor health status, and short information technology.

This study examined relevant literature to review the concept of low-income class, its criteria and types. Based on the cases surveyed, the service status of public libraries for low-income class in South Korea was determined. Based on the findings of this study, we proposed new library services necessary for low-income class, such as the implementation of relevant programs aimed at resolving the digital information divide of low-income class, the introduction of employment programs for the self-economic-support for low-income class adults, and the introduction of reading and counseling therapy services. In addition, this study proposed five policies for activating library services for the low-income class: (1) To revise the act on library law so as to clarify the concept of low-income class, its criteria and types, (2) to revise the master plan for library development so as to bolster the library services for low-income class, (3) to conduct a national-level survey of the low-income class status and of the library service status, (4) to determine the actual features of the low-income class and their information demands, and (5) to prepare library services tailored to the diverse types of low-income class.

The aim of this study was to evaluate the effect of application of the contents of Korean Information Center of Agricultura Safety and Health (KICASH) with 80 subjects(male: 60, female: 20) from different provinces nationwide in 2011. Subjects were classified according to their sex and familiarity of computer and then categorized into 3 groups with poor, medium and good by self-evaluation. The test for the effectiveness and satisfaction about KICASH was conducted with likert scale from very bad (1point) to very good (5point). Subjects generally tended to give 4 points to contents. And they gave support to KICASH in that they showed about 4 point with intention of application of KICASH for safety and health irrespective of familiarity of computer. However, as they received the information passively, it will be needed to develop more interesting and various contents which they could get more helpful information for their health and safety actively using two-way information communication system in future. Therefore the study can helps improve farmer's health and safety through developing advanced health and safety information system.

The purpose of this study is to provide a basic data of clothing development that can improve the satisfaction of the body shape by examining the subjective evaluation and characteristics of each type. The types of body shape of middle-aged women were analyzed as four types: elasticity loss ladder type, flat rectangular type, thin reverse ladder type, and upper body obesity inverted triangle type. The elasticity loss ladder type was developed with the lower body, and it was analyzed that the legs size such as the thighs and claves were large, the abdomen was protruded, and especially the underbelly appeared. The flat rectangular type was the largest of the four types, and was the skinny type. The width was larger than the thickness of the body, and the difference between the hip circumference and the waist circumference was small, and it was classified into a flat rectangular shape. The thin reverse ladder type was the smallest of the four types, the upper body was developed, the back had weight, and the body was leaning forward. And the lower body and leg were poor and the abdomen was protruding. Finally, the upper body obesity inverted triangular was the highest type of BMI index among 4 types. All of subjects belong to the mild and middle obesity, and the second was the smallest but the most weighted type among 4 types. They had the fat body and big bust, the upper body was developed, and the lower body and legs were analyzed to be poor body shape. Based on the body shape of middle-aged women, it is necessary to develop designs and patterns that can cover the shortcomings of body shape.

Purpose: This study was to investigate how dose the radiography findings are to magnetic resonance (MR) image findings in the L5-S1 instability patients. The subjects of this study were comprised of eleven males and fifteen females, who had Lumbago and agreed with this research. Methods: Radiography and MR images of Lumbar spine were acquired respectively from subjects in conditions of maximum flexion and extension. The horizontal and angular displacements in lumabosacral spine radiography were used to assess the instability of lumbar spine. MR images were also used to evaluate the intervertebral disc abnormalities and change of bone marrow. Results: The results are as follows. 1. In the case of flexion transitional displacement proposed by Dupuis et al, the specificity and negative predictive value were good accuracy ($0.7{\sim}0.8$), and the negative predictive value was in average. In the case of extension displacement, the negative predictive value was about average ($0.6{\sim}0.7$), but the sensitivity, specificity and positive predictive value were below the poor (<0.6). On the other side, the specificity was about average but other things were below in the case of angular displacement. 2. In the case of flexion transitional displacement proposed by Dupuis et al., compared with the intervertebral disc abnormalities, the negative prediction value was excellent, the sensitivity good, and the specificity about average. In the case of extension, the negative prediction value was about average, but the other things were poor. On the other side the specificity and negative predictive value had good accuracy and the sensitivity and positive prediction value were below average in the case of angular displacement. Conclusion: The above results show that the radiography finding is sufficiently helpful to find the lumbar spine instability as an economic point of view.

Most public libraries construct and operate their websites to provide the various user groups in local communities with internet access in Korea. But the representative public library's websites designed for children who are going to lead the next generation information based society, are unsatisfactory and don't reflect their approaches to information. The main factors of content and circumstance of usage are also extremely poor. Therefore, this research analyzed the construction of websites for children, their interface and design, search services, the contents of provincial representative public libraries amongst public libraries in korea and suggested improvement schemes.

WFQ(Weighted Fair Queuing) is the most popular fair queuing algorithm to guarantee the Quality-of-Service(QoS), but it has the inherent drawback of a poor resource utilization, particularly under the low rate traffic requiring a tight delay bound. It was recently identified that the poor utilization is mainly due to non-optimized latency of a traffic flow and then LOFQ(Latency-Optimized Fair Queuing) to overcome the drawback was introduced. The LOFQ algorithm, however, renews their optimal latencies for all flows whenever a new flow arrives, which results in the high implementation complexity of O($N^2$).This paper is to reduce thecomplexity to O(1). The proposed method is first to derive the optimal latency index function from the statistical QoS characteristics of the offered load, and then to simply calculate the optimal latency index of the arriving flow using the function.

The purpose of this research is to evaluate Seoullo 7017 based on Universal Design (UD) principles and guidelines. To derive UD principles applicable to the site context, we used the 2017 Seoul Universal Design Guideline and assessment index provided by the Universal Design Research Center and established 11 evaluation criteria. With respect to research methods, a literature review and on-site field survey were applied, through which we derived UD principles and evaluation criteria to identify UD problems. The 11 evaluation criteria consist of pedestrian space, facilities, access, main entrance, parking lots, trails, restrooms, convenience facilities, information facilities, rest areas, and playgrounds, and these were associated with UD principles for evaluation. As a result, the main entrance had the highest UD score, while parking lots had the lowest in terms of equity, safety, simplicity, and accessibility. Restrooms received a lower UD score because of poor conditions of security and alert systems. Rest areas were found to be uncomfortable for disabled people. With respect to the internal trails, we found the lack of braille block and irregular placement of planting pots made blind people uncomfortable when walking. In terms of UD principles, flexibility received the highest score, followed by amenity, equity, simplicity, tolerance, accessibility, and safety. Flexibility received the highest score, owing to the provision of proper information about convenience facilities and trails, while safety received the lowest, based on poor access to parking lots, inadequate paving materials and colors, and a lack of 24-hour security systems. We hope this research contributes to improving the universal design, so that people are not discriminated against in the use of the park in terms of age, sex, or physical disability. We expect the study to help facilitate empirical studies to verify UD principles and provide improved quality of UD for Seoullo 7017.

Transparent conducting oxide (TCO) films are widely used as transparent conducting thin film material for application in various fields such as solar cells, optoelectronic devices, heat mirrors and gas sensors, etc. Recently the increased utilization of many transparent electrodes has accelerated the development of inexpensive TCO materials. Indium tin oxide (ITO) film is well-known for TCO materials because of its low resistivity, but there is disadvantage that it is too expensive. ZnO film is cheaper than ITO but it shows thermally poor stability. On the contrary, antimony-doped tin oxide films (ATO) are more stable than TCO films such as Al-doped zinc oxide (AZO) and ITO. Moreover, SnO2 film shows the best thermal and chemical stability, low cost and mechanical durability except the poor conductivity. However, annealing is proved to improve the conductivity of ATO film. Therefore, in this work, antimony (6 wt%) doped tin oxide films to improve the conductivity were deposited on 7059 corning glass by RF magnetron sputtering method for the application to transparent electrodes. In general, of all TCO films, glass is the most commonly selected substrate. However, for future development in flexible devices, glass is limited by its intrinsic inflexibility. In this study, we report the growth and properties of antimony doped tin oxide (ATO) films deposited on PES flexible substrate by using RF magnetron sputtering. The optimization process was performed varying the sputtering parameters, such as RF power and working pressure, and parameter effect on the structural, electrical and optical properties of the ATO films were investigated.

In this paper, we propose a watermarking technology for a mixed music. The mixed music means recreated music that contained a number of musics in one audio clip. Royalty associated with the audio content is typically imposed by the full audio content. However, the calculation of royalties gives rise to conflict between copyright holders and users in the mixed music because it uses not full audio content but a fraction of that. To solve the conflict related with the mixed music, we propose a audio watermarking technique that inserts different watermarks for each audio in the audio that make up the mixed music. The proposed watermarking scheme might have poor SNR (signal to noise ratio) to embed to each audio clip. To overcome poor SNR problem, we used inaudible pseudo random sequence which modifies typical pseudo random sequence to canonical signed digit (CSD) form. The proposed method verifies the performance by each watermark extraction and the time internal estimation valies from the mixed music.
