Results of experiments on the nutrient requirements and feeding system of broiler breeder hens were reviewed, and daily requirements of energy and protein were calculated using the prediction equations reported by Scott(1977) and NRC(1981). The experimental reports on daily ME needs of broiler breeder hens were ranged from 400 to 450 kcal, however, the ME needs of caged hens were 92~93% to those of floor-housed hens due to the difference of ME need for activity. The ME needs of broiler breeders decreased with increasing environmental temperature corresponding to a drop of 25 kcal per day for each 5˚C rise. About 80~90% of the daily ME needs were used for body rnaintenance and activity of hens. Experimental results on daily protein needs of broiler breeder hens were ranged from 18 to 22 g, however, calculated protein needs decreased as the BW gain and eggmass output decreased after peak production, and about 60~65% of the daily protein needs were used for egg production. In the current practice, broiler breeder hens are restricted in feed, and consume their daily allowance in the first 2 to 6 h after dawn. The results suggest that eggshell quality can be significantly improved in hens fed during the afternoon when shell calcification is initiated, with no adverse effect on laying rate and fertility of eggs.

The nutritional value of Korean traditional diet was estimated by using the 7-dish meal of Kim Ho Jik (1944) and the standard weekly menu of Bang Sin Young (1957), and compared to the current Recommended Daily Allowance of Korean. The Korean traditional diets were estimated to be able to supply 2,000-2,500 Kcal and 80-90g of protein per day. The constitution of energy was made by 73-77% carbohydrate, 15-18% protein and 10-12% lipid. The content of animal protein was 20-30% of total protein. The Korean traditional diet could supply sufficient amounts of protein, minerals and vitamins for an adult male, if the energy intake exceeds 2,00 Kcal per day.

This paper describes the buckling phenomenon of a tubular truss with unsupported length through a full-scale test and presents a practical computational method for the design of the trusses allowing for the contribution of torsional stiffness against buckling, of which the effect has never been considered previously by others. The current practice for the design of a planar truss has largely been based on the linear elastic approach which cannot allow for the contribution of torsional stiffness and tension members in a structural system against buckling. The over-simplified analytical technique is unable to provide a realistic and an economical design to a structure. In this paper the stability theory is applied to the second-order analysis and design of the structural form, with detailed allowance for the instability and second-order effects in compliance with design code requirements. Finally, the paper demonstrates the application of the proposed method to the stability design of a commonly adopted truss system used in support of glass panels in which lateral bracing members are highly undesirable for economical and aesthetic reasons.

The purpose of this research is to analyze Korean and Japanese junior high school and high schools students to inquire into the attitudes these students have towards credit, the importance of credit related education, and the necessity of education on online credit. This will provide an insight into the problems associated with teenage credit related consumer education, and allow a solution to be brought up. The results of the research and the proposal are as follows. First, younger Korean teenagers are more passive in consumption than the same age group in Japan. Second, for Korean teenagers, the amount of allowance and savings were an important factor in the attitude towards credit. In Japan there was a discrepancy between gender groups in the attitude towards credit. Third, personal education sessions for teenagers and follow up is necessary. Fourth, since the current teenage population have been familiar with the internet all their lives, credit education should utilize this medium as a tool. Fifth, when looking into the requests Korean and Japanese young teenagers made on credit web sites, the contents and quality of information is more important than the outlook of the site itself. Sixth, there is a need to provide teenagers, who are accustomed to visual data, information, an experience opportunity, and access to related web sites.

A feature line is a visually noticeable creased line on outer automotive panels. Feature lines play an important role in creating a good impression of a car. Even though the manufacturing quality of feature lines is important, it is difficult to achieve the designed shape owing to the springback of sheet metal. The current study presents five methods of making samples that will be used in a visual experiment to discover a quality control quantitative manufacturing allowance for feature lines. Measurement and inspection methods for the samples are also presented. The results show that plunge machining is the most accurate way to make the desired shape, and that wrapping the machined surface with sheet film is an appropriate way to emulate the roughness and visual texture of the painted outer panels of a car.

Since Personal Information Protection Act came into effect on September 2011, PIA(Privacy Impact Assessment) of public institutions has become obliged. Therefore, an increasing demand for PIA professionals is being expected. In domestic, however, no specialized certificates exist and therefore similar certificates have become a requirement for PIA professionals. Henceforth, however, the system based on these similar certificates is to be an obstacle to advancing PIA. Therefore, this study analyzes the sufficiency of current similar certificates compared with the PIA qualification requirements. And then, analyzes the validity of allowance as similar certificates by using this outcome of the validity. As this comparison draws a clear gap between PIA qualification and similar certificates, this paper suggest three suggestions to improve current qualification. Three suggestions are expected to contribute a qualitative improvement of the PIA industry.

The maintenance and improvement of housing become more important than quantitative supply. So this paper suggests the directions to solve the current issues of housing improvement policies. In 2015, the housing improvement for the low-income has been expanded with the revision of housing benefit policy. And each related government departments are steadily carrying out various housing improvement programs. Under the current improvement policies, individual houses are being repaired according to the criteria of the target selection. And the repair allowance of the housing benefit is limited to the ownership households except the rented. Hereafter, it has to considered the review of the detailed goal setting and application problems in housing improvement policy and to consider the extension to the rented households and the raise of the income criteria of targets. Also, it needs to carry out the improvement of several neighboring houses at the same time for synergy effect other than individual house, to change the selection way of repair contractors and to secure the quality and advancement of the improvement.

College students are the potential income classes preparing for income activities and are the main consumers of the future that are very important. In order to understand the current state of ginseng-related consumption culture of young consumers, this study wanted to examine university students' attitudes toward ginseng-related products and services in the future, and to find out their purchasing status, satisfaction, and intent to purchase them. In doing so, we looked at the relative influence of the relevant variables that affect the intent of the purchase. As a result, the variables that affect college student consumers' intention to purchase ginseng-related products were shown in the order of their reliability, economy, purchasing experience, subjective interest, monthly income, monthly allowance, pride in ginseng, and age. Of these, most of the variables had positive effects, but the average monthly income, monthly allowance, and age had negative effects. In other words, the higher the reliability, economy, and self-esteem of ginseng, the higher the willingness to buy ginseng, the higher the subjective interest in ginseng, the higher the age, the lower the monthly allowance, and the lower the income, the lower the willingness to buy ginseng. To promote college students' consumption of ginseng products, it is necessary to cut prices for the younger generation, enhance the quality of the products for the younger generation, improve the taste to overcome the negative aspects of rejecting the bitter and bitter taste, and, above all, induce consumers' attention. It is also necessary to expand accessibility through the development of convenient and easy-to-eat products for young people and the expansion of sales outlets. Recently, young consumers are interested in new products they have never experienced before, products that are good to certify because of their unique design or packaging, and retro products that stimulate nostalgia in the past, so they need to promote and provide information related to consumption of ginseng products in this regard. Considering the practicality and convenience of consumers, we propose consideration of personal consumers' taste curation services, which reflect their preference for products that are convenient to carry with them in line with various living environments, and can have synergy with other products.

The history of rehabilitation of disabilities in Korea began with the foreigners and missionaries who were interested in it after Korean War. In 1981, Disabled Persons Welfare Act was enacted and the 88 Paralympics brought the nations attention to the welfare and rehabilitation of persons with disabilities. Since then, the facilities and the services for the disabled persons have expanded rapidly and the rehabilitation treatment and nursing intervention are drawing more attention. Against this background, the survey on the current status of disabilities, welfare service, facilities, and rehabilitation nursing was conducted. The results of this survey are as follows. 1. According to the 2000 census of disabilities, the number of persons with disabilities in Korea is estimated at 1,449,500, or 3.09% of the entire Korean population, 0.74% up from 2.35% in 1995. 2. Disability Types in 2000 The 2000 census showed that the persons with disabilities numbered 1,449,496 out of the total population and 1,024,371 persons are registered for disability, making up 70.7% of the estimated disabled population. Among them, physically disabled persons accounted for the largest 41.7% (605,127) and mentally retarded persons stood at the smallest 9% (13,481). 3. Percentage of Disability Presence The survey showed that more than 90% of disability were acquired. However, 44.8% of mental disability and 61.4% of hearing/speaking disability were not acquired after birth. This means that these disabilities happened by congenital cause or birth accident. 4. Yearly Figure of Registered Disabled Persons In 1989, 218,601 persons registered for disability and, in 2000, the number increased by 4.7 times to 1,024,371. These figures are different from the actual number of disabled persons. According to the 1995 census, 1,053,486 were disabled persons but only 378,323registered for disability. And, in the 2000 census, 1,024,371 out of the 1,449,496 of disabled persons registered for disability. 5. Welfare Service for Persons with Disability 62.6% of the total disabled people are registered and physically disabled persons accounted for the highest percentage of 96.7%. 26.5% of non-registered disabled people said that they didnt know the registration procedure. The rest of them replied that they didnt think they were disabled or that registration didnt seem to give any benefits. 6. Welfare Policies for Disabled Persons The welfare benefits given to the disabled are as follows: Issuance of disabled sign for car drivers, Permission to use LPG fuel, Communication fee reduction, Tax exemption related to cars, Reduction of public facility fees, Household allowance, Tax reduction or exemption, Medical allowance and education subsidy for children, and Housing. 7. Current Condition of Welfare Facilities by Disability Type The welfare institutions for disabilities numbered 188 in total and they can accommodate 16,823 persons. Categories of these institutions are physical disability(37), visual disability(10), hearing/speaking disability(14), mental retardation(59), and sanatoriums(68). 8. Human Resource of Rehabilitation of Disabilities Advanced education programs include rehabilitation nursing in its curriculum and this was selected as the program of Korean Academic Society of Nursing in 1990. In November 1997, Korean Academic Society of Rehabilitation Nursing was launched and many academic meeting and seminars were held. This organization is also making efforts to develop the education program for qualified rehabilitation nursing professionals and to develop the standards of rehabilitation nursing practice. In the professionals of the rehabilitation, there are rehabilitation specialist, physical therapist, speech therapist, occupational therapist. It is needed to come up with the measures to supply stable human resources following the demand of disabled persons and to recognize the private certificates for rehabilitation professionals as official ones after reviewing the education and training programs of private institutions. 9. Rehabilitation Nursing 1) Rehabilitation nursing was taught as an independent subject in 11 undergraduate programs and 9 graduate programs. 2) Research on rehabilitation nursing in Korea were 24 experimental research and 11 non-experimental research. The intervention of experimental research were mostly education and exercise rehabilitation programs. 3) In the three rehabilitation hospitals, nursing is divided into two categories, direct nursing and education & counseling. Direct nursing includes tracheostomy or nasogastric tube care, urination and defication, skin care, pain control, complication prevention and care, prevention of injury from a fall, etc.

In this paper, we employed a model which defines the sensitivity according to the background luminance, so called JND (Just Noticeable Difference), and applied to the video coding. The proposed method finds out the maximum possible quantization parameter for the current unit based on the threshold of JND model and reduce the bitrate with similar perceptual quality. It selects the higher quantization parameter and reduce the bitrate when the reconstructed signal which is coded with higher quantization parameter is in a range of allowance based on the JND threshold, i.e. the signal has the similar perceptual quality compared to that is coded with the initial quantization parameter. The proposed algorithm was implemented on HM16.0, which is a reference software of the latest video coding standard HEVC (High Efficiency Video Coding) and the coding performance was evaluated. Compared to HM16.0, the proposed algorithm achieved maximum 20.21% and 6.18% of average bitrate reduction with the similar perceptual quality.
