Objective: This study aims to develop a new desk with a built-in bookholder and desktop-mounted sliding drawer for reducing stress of seated reading postures and to analyze its effect. Background: It is general for readers to bend their back and neck when reading books on desks, which may result in high back and neck postural stress. In addition, postures using vertically layered drawers positioned at the side of users may be awkward. Method: For reducing the postural stress, a new desk with a built-in bookholder and sliding drawer was developed based on a standard of KS G 4208 for student desk. The muscle activities of reading postures on both existing and new desks were measured using EMG, in which seven male and three female college students participated. The postural stress, and musculoskeletal discomfort and ease of usage for existing and new drawers were analyzed by RULA and questionnaire survey, respectively. Results: Compared to existing desk, the muscle activity for the new desk with a bookholder was reduced by 47% when reading books. In addition, musculoskeletal discomforts in the shoulder, neck and low back were significantly lower when using the new desk with a bookholder. Although the stresses for postures using the desktop-mounted sliding drawer and general drawer were not significantly different, the questionnaire survey revealed that the new desktop-mounted sliding drawer is easier to use. Conclusion: A new desk developed in this study significantly reduced postural stress and enhanced subjective preference when reading. Application: This would be useful when developing new desks with low postural stress.

The historical consciousness of furniture is one of the crucial elements that become the medium for initiating design. Also, it is an important task of the science to figure out the headstream of furniture being used these days. From this purpose, this study intends to understand the bureau that has not been studied much in terms of the headstream and changes based on historical facts centering around England, France, or America regarding the forms or terms. These points are expected to be used as the foundational research data to develop the science and products.

This was a systemized bed consisted of storage units, a desk, a drawer, a sofa and a shelf. This bed system was not designed only for a certain age group of children but also for various age groups of children, since each parts of the bed can be sued separately. Separation of parts of the bed allowed children to decorate their own living space and gives them a chance to express their own feeling and thoughts by layout of parts. Design adopts the beauty of nature such as smoothly curve lines which are perfectly fit for the children's living space. The moving sofa located under the bed and the book shelf lead children to establish a pattern of reading habit. The draw and storage units offer nice space for keeping children's goods.

This study examines the spatial compositions of children's reading rooms, furniture characteristics, and users' satisfaction levels for the furniture in public libraries. Field measurements and surveys were performed in 5 public libraries. Results imply that the spatial compositions of reading rooms in libraries were classified into three categories according to the locations of bookshelves and reading space. Management areas should not be located at the edge of reading rooms but be located at the center of reading rooms to avoid clerks' narrow viewing angle toward young kids and to ensure security for the kids. The evaluation for bookshelves according to evaluation checklists was acceptable, but users were not always satisfied with the bookshelves due to the inappropriate positions of books in shelves. The evaluation for desks was generally acceptable according to the checklists and users were satisfied with them. In general, the desk with higher scores by the checklist provided better satisfaction to users. However, the score by checklist for chair and user satisfaction were not always similar each other. Convenience areas in reading rooms were not enough compared to bookshelf, reading and management area. Computer tables that were designed in a way that users sit down and use the computers were highly preferred.

In the structure of modern houses, a living room is the space most frequently used by family members. In a living room, they rest, talk together, watch TV, study, read books and enjoy hobbies. A living room is furnished with a TV cabinet, a storage closet, a sofa, a bookshelf, a desk and etc. depending on the purposes of activities in it, which can be different in each house. Furniture is the required tool for indoor architectural space and humans to lead a life. In most families, a man and a woman marry each other and become man and wife, go through the honeymoon phase, give birth to one or two children and become a family with three or four members. According to the children's growth cycle from birth to infancy, early childhood, childhood, adolescence, youth and adulthood, furniture layout and kinds of furniture in a living room change. Depending on the family life cycle, most parents of young children try to help their children to form good habits of reading books and studying for their future. As for the environmental elements interrupting reading and studying, watching TV and using smart phones excessively are being regarded as problems. As the number of two-income families is increasing in this era when many women are participating in the social activities with the government's encouragement, children are having more time.

In the present study the meaning of table in the Joseon dynasty period and also in the present age was researched, and its changing according to the times was searched as well. The results are as follows. First, the meaning of table in the Joseon dynasty period and in the present age has one thing, "laying something on table" in common from the functional aspect. Whereas the table in the Joseon dynasty period had the function of laying and keeping articles or decorations, that of the present age contributes to reading and doing office work of human beings and this exceeds the simple function to keep articles, because it touches parts of the human body, so it combines function of comfort accordingly, not only the function of storage. Second, it was differently presented from the aspect of shape. The table of the Joseon dynasty period strongly showed the shelf-like shape due to the set-up in layers, while the table of the modern times has the rectangle-like form in one layer. It has been transformed according to the functional changes. Third, it is different also from the constructive aspect. The table of the Joseon dynasty period had the construction with one panel on 4 legs in layer upon layer, but the table today has one upper panel on legs supporting it. Namely, the term "table" has been constantly used from the Josen dynasty period until today, but it has a totally different meaning according to the times on the basis of the changes in function and shape. In the furniture which maintains the function and shape of the square-typed table with 3 or 4 layers and the book table in the Joseon dynasty but is used under the different term in the present times it can be counted that display cupboard or bookshelf. Furthermore, desk and tea table can be regarded as furniture which exactly corresponds with the term "table" used in the present days, and also in the Joseon dynasty period there were furniture with such same function as like the writing table and small dining table.

The purpose of the study is to suggest the amount of space for each behavior according to the classification of behavior in the housing to plan the optimal floor space of the elderly housing. The method for calculating space for behavior begins with classifying behaviors, identifying them and then taking pictures of the model of elderly people who reproduce each behavior. Based on the pictures, body parts which are necessary for each behavior are assembled and the formula for behavioral space is created. The space for behavior is produced considering the body dimensions of Korean elderly in their sixty's as well as the furniture size and the psychological distance between people. 3D modeling is used to verify the result. Human behaviors can be classified into individual-related, housework-related, family-related, reception-related and other behaviors. These five behaviors are subdivided into more specific behaviors. The area for each specific behavior is calculated with the anthropometric data of the elderly, preferred furniture dimension and psychological area. As a result the required area for specific behaviors is as follows: the behavior of sleeping in a bed needs $4.3m^2$; the behavior of changing clothes on a chair, $1.7m^2$; the behavior of watching TV on the floor $1.3m^2$, the behavior of working and reading using a desk, $2.1m^2$, the behavior of exercise, $2.5m^2$; the behavior of showering on a chair, $1.3m^2$ and showering using a wheelchair, $1.9m^2$; the behavior of toileting using a wheelchair, $2.3m^2$; the behavior of washing up using a wheelchair, $1.9m^2$; the behavior of eating using a table for four persons, $4.4m^2$; the behavior of cooking and washing dishes, $0.9m^2$ per counter-top; the behavior of washing clothes using a washing machine, $0.9m^2$; the behavior of ironing on the floor $1.4m^2$; the behavior of reception(three persons) on the floor considering personal space, $4.0m^2$; the behavior of taking on and off shoes on a chair, $1.3m^2$. The result of the study is utilized as quantitative data to calculate optimal floor space for elderly housing. In addition, qualitative data such as characteristics of housing preference, spacial usage and storage capacity are necessary to produce the floor space which can provide convenient and safe living environment.

국내의 경우 방사선작업종사자의 개인피폭관리는 선량한도를 초과한 피폭의 유무를 확인하여 사후 조치를 취하는 것에 초점이 맞추어져 있다. 그러나 의료기관 핵의학과의 경우 개봉선원을 사용하므로 작업환경이 방사선에 노출될 가능성이 많고, 방사성의약품 투여 후 수 시간 혹은 수 일 동안은 환자 자체가 방사선원이 되므로 방사선작업종사자나 수시출입자, 환자보호자들의 방사선 피폭 가능성이 매우 높다. 따라서 환자보호자 등 일반출입자의 방사선피폭을 방지하기 위해서는 환경방사선관리가 적절하게 실시되어야 한다. 일본에서는 "방사성동위원소등에 의한 방사선장해의 방지에 관한 법률" 등에 근거하여 방사선작업환경에 대한 환경방사선량을 정기적으로 측정, 보관하도록 하고 있다. 이에 대전시 소재 대학병원 핵의학과에서 일본에서 시행하고 있는 것과 같은 방법으로 핵의학과 내 8개소에 유리선량계를 설치하여 환경방사선을 측정한 결과 8개소 모두 "진단용 방사선 발생장치의 안전관리에 관한 규칙"에 규정된 방사선구역의 외부방사선량인 주당 0.3 mSv에는 훨씬 미치지 못하는 적은 선량이 측정되었다. 그러나 접수대에서는 3개월 누계 선량률이 0.51 mSv로서 접수대 종사자는 일반인 연간 유효선량한도인 1 mSv를 초과할 가능성이 높았으며, 환자 및 보호자 대기실에서도 0.23 mSv(3개월 누계치 0.69mSv)가 측정되어 유리선량계를 설치한 8개소 가운데 가장 높은 선량률을 보였다. 이것은 일반인의 연간 유효선량한도인 1 mSv를 초과하는 값이며, "방사선방호 등에 관한 기준 고시"에 환경상 위해방지를 위해 규정된 연간 유효선량 0.25 mSv를 초과하는 값이다. 따라서 접수대 근무자, 환자보호자 및 제3자 보호를 위해 핵의학과 내 환경방사선량 감소를 위한 적극적인 대책이 필요한 것으로 나타났다.
