Objectives: The purpose of the study is to investigate recognition and adequacy of dental service providers regarding dental prosthodontic treatment covered by dental auto insurance system. Methods: A self-reported questionnaire was completed by 320 dentists and dental hygienists in Seoul, Gyeonggido, and Incheon from February 22 to March 21, 2016. The questionnaire consisted of recognition and needs of auto insurance (4 items), and recognition of prosthodontic treatment covered by dental auto insurance system. Likert five point scale was used in the questionnaire. Data were analyzed by SPSS 21.0 program. Cronbach's alpha was 0.856 in the study. Results: The average of recognition was 2.62 and that of adequacy of auto insurance coverage was 1.98. The reasonable price of crown treatment was from 400,000 to 500,000 Korean Won in 67.9 percent of the dentists. But 49.8 percent of the dental hygienists answered that the reasonable price of crown was 300,000 to 400,000 Korean Won. The dentists preferred to treatment fee covered by dental auto insurance. The dental hygienists had a preference to combination of dental auto insurance and medical insurance fee. Conclusions: The opinion of the dental care providers should be considered and the adequate coverage of insurance would improve the dental health care.

Organic matter in dredged soil has a lot of engineering problem in ground including a large settlement, crack propagation, low bearing capacity and low friction angle. From an agricultural point of view, however, organic matter contributes greatly soil quality and plant health. This paper investigated the relationship between engineering and germination characteristics of stabilized mixture consisting of different ratios of organic content (0 %, 10 %, 20 %, 30 %) for recycling dredged soil including organic matter. Several series of laboratory tests such as flow test, unconfined compressive test and consolidation test were performed to find out engineering characteristics. pH, percent of germination and growth of plants were also measured to investigate the germination characteristics. The experimental results indicated that, as organic content increased, unconfined compressive stress decreased and compression and swelling indices increased. However, percent of germination and plant growth increases as organic content increases.

Toll-like receptors (TLRs) play an important role in the recognition of invading pathogens and the modulation of innate immune responses in mammals. The TLR4 and TLR7 are well known to recognize the bacterial lipopolysaccharide (LPS) and single stranded (ssRNA) ligands, respectively and play important role in host defense against Gram-negative bacteria and ssRNA viruses. In the present study, coding exon fragments of these two TLRs were identified, cloned, sequenced and analyzed in terms of insertion-deletion polymorphism, within bovine TLRs 4 and 7, thereby facilitating future TLR signaling and association studies relevant to bovine innate immunity. Comparative sequence analysis of TLR 4 exons revealed that this gene is more variable, particularly the coding frame (E3P1), while other parts showed percent identity of 95.7% to 100% at nucleotide and amino acid level, respectivley with other Bos indicus and Bos taurus breeds from different parts of the world. In comparison to TLR4, sequence analysis of TLR7 showed more conservation among different B. indicus and B. taurus breeds, except single point mutation at 324 nucleotide position (AAA to AAM) altering a single amino acid at 108 position (K to X). Percent identity of TLR7 sequences (all 3 exons) was between 99.2% to 100% at nucleotide and amino acid level, when compared with available sequence database of B. indicus and B. taurus. Simple Modular Architecture Research Tool (SMART) analysis showed variations in the exon fragments located in the Leucine Rich Repeat (LRR) region, which is responsible for binding with the microbial associated molecular patterns and further, downstream signaling to initiate anti-microbial response. Considering importance of TLR polymorphism in terms of innate immunity, further research is warranted.

The purposes of this study were to investigate the customers' perception on nutrition information provided on a family restaurant menu, to examine customers' intention to use the nutrition information when eating out if nutrition information would be provided, and to identify what kinds of nutrient information the customers want. A total of 265 respondents were answered. Female was sixty-six percents, and eighty-four percent of the respondents was less than thirty-five years old. The patrons' perception about nutrition information on the menu showed the level of 2.5 points out of 5 points, which pointed out that family restaurant patrons were not satisfied with receiving nutritional information related to the menu. The customers perceived that restaurants had responsibilities for providing nutritional information about menu items. Sixty-six percent of respondents showed a positive intention to the question item about how much the customer would use nutritional information provided on the menu. The customers, who were female (p<0.05), who had a good health status, who showed higher interest on weight control (p<0.01), and who were health-oriented (p<0.01), showed the higher intention to use nutritional information. Nutrient information in which the customers were interested strongly was a fat content, followed by cholesterol content and calorie information. According to the trends of eating out, preferring family restaurants, and increasing interests in a healthful menu, nutrition information demand in restaurant operations would be increased rapidly in the near future. Providing nutrition information at the point of menu choice might result in the improvement of customers' nutritional and health status by encouraging proper dietary habits of patrons as well as providing nutritional education. Therefore, it is recommended that government and restaurant firms should recognize the importance of nutrition information and make strategic plans for the future.

Uniform silica nanobeads were synthesized by St$\ddot{o}$ber method and assembled in the form of monolayer on glass substrate using sonication method. Before the assembly of silica nanobeads, glass substrates were treated with molecular linkers, such as CP-TMS and PEI, and nanobeads were dispersed in toluene. In attachment test, SO (sonication without stacking) method and SS (sonnication with stacking) method was used and sonication time was controled. After the experiment, microbalance was use to measure deviation between before and after the attachment experiment then calculate percent of coverage. Minutely observe with SEM (Scanning Electron Microscopy) then select the most close-packed and monolayer assembled cover glass and calculate DOC (Degree of Coverage). In SO method, DOC increased very sharply and reach over 140 percent point, also got lots of multi-layer region. On the other hand, in SS method DOC increased slower than SO method but more close-packed and monolayer assembled.

On December, 1996, Construction Management(CM) was introduced in Korean construction industry due to its managerial efficiency proven in the international construction industries. However, It have had serious problems with many regulations, standards, manuals and details of practices considering its constituents and industry conditions. Especially, there were controversial points in the CM fee estimate; difference between the fee on the owner's view point and that from contractor's that impedes appropriate CM services. Therefore, this paper is to analyze public construction projects into Cm fee calculation such as fee as a percent of construction cost, cost plus fixed fee and contract price, and analyzed what is irrationality and why irrationality is made. So it makes a contribution to a study on standards for paper CM fee calculation.

This study was performed to assess the perception and need for the elderly meal service program of the Korean elderly. The purpose of this study was to assess the dietary environment factors which are related to the perception and need for such service. Subjects of this study were 800 elderly persons of whom responses were received from 769(male: 26, female: 543) aged over 60 years. Their mean age was 7.51 $\pm$8.1 years. Seventy two point two percent of them lived with their family and 54.5% of them were supported economically by their children. Among their meal management behaviors, food purchasing was hard to perform and the most aid-needed activity. In their dietary environment, 47.1% of them were supported by their children. The percent of the subjects who were aware of the elderly meal service program was 48.4%. Men were more aware of the meal service program than women(p<0.01). Elderly who were supported by government were more aware of this service than others. Elderly who were in poor dietary environment, were less affluent or had trouble preparing meals expressed better perception this service than others (p<0.05). Those who requested meal services had poor dietary environment than those who did not (p<0.001). The elderly who were younger, with higher income, and lived with a spouse had more demand for home delivered meal service. This study showed that the poorer the greater desire for meal services. Therefore, the need for urgent improvement and expansion of meal services for elderly is suggested by this study.

Background: The aim of this study was to evaluate trends in incidence of breast cancer in women less than 40 years in Asia. Materials and Methods: Registered cases of female breast cancer age less than 40 years and corresponding person years were ascertained from the CI5plus for 10 registries in Asia for the duration of 1970- 2002. Cases were categorized into three age groups: 16-40, 16-29, and 30-40. The 16-40 age group was adjusted to world age population structure. Joinpoint regression analysis was conducted to determine the annual percent of change (APC) and the average annual percent of change (AAPC) for each age group. Results: A total of 23,661 cases of breast cancer occurred in the 10 registries during the 32 years (1970-2002) of follow-up. The overall age adjusted (16-40 group) breast cancer incidence rate increased from 2.28-4.26 cases per 100,000 population corresponding to an AAPC of 2.6% (95%CI 2.1, 3.0). The trend in incidence for the age group 16-29 increased from 0.45-1.07 corresponding to an AAPC of 2.8% (95%CI 1.9, 3.7). In age group 30 to 40, the incidence ranged from 13.3 in year 1970 to 24.8 in year 2002 corresponding to an AAPC of 2.7% (95% CI 2.3, 3.1). There were two statistically significant changing points in the regression line for the age groups 30-40 and 16-40: one point in the year 1975 with an APC of 6.1 (5.1, 7.1), and the other in 1985 with an APC of 0.4% (0.01, 0.8). Conclusions: Our study proved that: 1) the incidence of breast cancer in young women has increased in Asian population during the study period; 2) the rate of increase was very high during the period of 1980-1990.

1. Objectives: We surveyed the attitude and awareness of Sasang Constitution investigators on informed consent in clinical study. This study was performed in order to improve the quality of ethical aspects in clinical study by surveying the process of obtaining informed consent. 2. Methods: We sent the questionnaire by email to Sasang Constitution investigators who had the experience in clinical study. The question was about the necessity of informed consent and the process of obtaining it. 3. Results: Twenty-two out of 24 questionnaires were collected. All of investigators recognized that informed consent is needed for clinical study. Sixty-four percent of the respondents 'fully' or 'mostly' explained the informed consent but they added only 41% of participants 'fully' or 'mostly' understood. Fifty-four point five percent of respondents provided participants enough time and opportunity to inquire the study in details to decide whether or not to participate in the study, the rest of respondents obtained informed consent without providing enough time for decision. 4. Conclusions: Sasang Constitution investigators had high awareness of necessity for informed consent in clinical study. But participants' understanding was low despite of the degree of investigators' explanation. A various strategies should be designed for improving consent forms and process. Most of all, investigators should make sure that informed consent intends to protect participants and promote ethical research conduct.

This study explored the characteristics, housing deficits and expectations for support programs of low-income renter households in housing poverty in order to provide housing policy development and improvement information. Microdata of the 2014 Korea Housing Survey was utilized as secondary data for this study. A total of 2,508,672 low-income renter households (weighted count) in the bottom 40% income ranks of entire general households living in private rental units were selected as study subjects. The major findings were as follows. (1) One point four percent of the subjects were living in non-house living quarters (e.g., shanties, vinyl greenhouses, container houses, and mud huts), 1.4% were in dosshouses, 9.9% were in basements, semi-basements or rooftop units, and 8.2% were in sub-standard units. (2) Among the households whose housing costs burdens were measurable, 75.7% were found to have housing cost burdens to pay 30% or more of their household income towards housing costs (rental costs and maintenance costs), but only 7.5% of the burdened households received a housing voucher. (3) Eighty-one percent were found to be in a housing poverty status as defined by the researcher; in addition, low-income renter households in housing poverty in Seoul tended to have a greater proportion of households headed by females, the elderly, and be persons with low-education or disabilities. (4) Households in housing poverty showed greater expectations for financial support and/or extended provisions of public rental housing than other low-income renter households.
