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.

An open reading frame coding for mannanase predicted from the partial genomic sequence of Paenibacillus woosongensis was cloned into Escherichia coli by polymerase chain reaction amplification, and completely sequenced. This mannanase gene, designated man26AT, consisted of 3,162 nucleotides encoding a polypeptide of 1,053 amino acid residues. Based on the deduced amino acid sequence, Man26AT was identified as a modular enzyme, which included a catalytic domain belonging to the glycosyl hydrolase family 26 and two carbohydrate-binding modules, CBM27 and CBM11. The amino acid sequence of Man26AT was homologous to that of several putative mannanases, with identity of 81% for P. ihumii and identity of less than 57% for other strains of Paenibacillus. A cell-free extract of recombinant E. coli carrying the man26AT gene showed maximal mannanase activity at $55^{\circ}C$ and pH 5.5. The enzyme retained above 80% of maximal activity after preincubation for 1 h at $50^{\circ}C$. Man26AT was comparably active on locust bean gum (LBG), galactomanan, and kojac glucomannan, whereas it did not exhibit activity on carboxymethylcellulose, xylan, or para-nitrophenyl-${\beta}$-mannopyranoside. The common end products liberated from mannooligosaccharides, including mannotriose, mannotetraose, mannopentaose, and mannohexaose, or LBG by Man26AT were mannose, mannobiose, and mannotriose. Mannooligosacchrides larger than mannotriose were found in enzymatic hydrolyzates of LBG and guar gum, respectively. However, Man26AT was unable to hydrolyze mannobiose. Man26AT was intracellularly degraded into at least three active proteins with different molecular masses by zymogram.

The purpose of this study was to investigate elementary students' difficulties when they read the illustrations on scientific textbook. 5 illustrations were selected on basis that they had some of the textual/graphical features. The data were collected from open-ended questionnaires and follow-up interviews. To investigate difficulties of reading illustrations, 100 sixth grade students participated in this study and interviews were taken to 9 volunteers among those participants. The results showed that many students had difficulties in the integration of verbal representation and realistic image representation on the illustration, therefore they often misunderstood the meaning of illustration. These results gave several recommendations when we used illustrations as educational materials. Teachers would be better to guide that students could understand illustrations with the integration of the reading of one or more representations.

Recognizing the importance of reading, and with one motivation being to encourage an upright reading culture, 138 Wise Sayings related to reading by Western leaders were investigated and analyzed according to their country of origin and content as well as the nationalities and occupations, achievements and activities, and the periods of activity of he people who said them. In Wise Sayings related to reading, there are connotations of reading's significance$(30\%)$, methods$(44\%)$, Usefulness$(13\%)$, values$(12\%)$, joys$(1\%)$ and so on, and the expressions vary according to the speakers' occupations. Many of the speakers of wise sayings related to reading were from the powerful and culturally-developed countries of England(36), France(17) and the United states(15), and among 168 occupations, many were engaged in literature(97), philosophy(20), and politics(13) In the field of literature in particular, poets(24), writers(24), and novelists(19) comprised about $70\%$ of the total. In terms of the periods of activity, the 19th-20th century with $33\%$ and the 19th century with $27\%$ made up $60\%$ of the total.

The purpose of this study was to compare what meanings of earth science pre-service teachers and primary pre-service teachers about science books and reading through science disciplinary reading and how their thoughts on science education are reflected in the science disciplinary reading process. For the study, 24 third-year students majoring in earth science education and 25 second-year students majoring in primary education were selected as subjects for the study at a teacher training college located in the central part of Korea. As a result of the study, first, earth science pre-service teachers used disciplinary reading a lot to acquire knowledge of science content, but primary pre-service teachers used it for the purpose of using it in class, scientific interest, and curiosity solution. Second, earth science pre-service teachers and primary pre-service teachers showed differences in their thinking in using science related books for science education. While earth science pre-service teachers rarely described the use of science books in their classes, primary pre-service teachers actively described science classes. Third, from the perspective of science disciplinary reading, primary pre-service teachers were more actively emphasizing the meaning of disciplinary reading compared to earth science pre-service teachers. In light of the research results that the reading activity in science has a lot of effect, it is thought that a wide range of research on science disciplinary reading should be conducted as a teaching strategy in school field classes.

Purpose: This paper studied the effect of eyes on the comparison between the distance optical centers problem of dispensing reading glasses made by optician and finished reading glasses in the current market. Methods: The method of this study has been measured by eleven different categories from +1.00D to +4.00D. This study also separated into three groups by their optical frame size and measured optical center point (O.C) and optical center height (O.H) with 200 peoples of man and females over 40 years old without ocular disease living in Gwang-san gu, Gwang-Ju city. Results: As a result, optical center point ranged from 57 mm to 80 mm and it turned to be most common range is from 61 mm to 65 mm (64.6%). Moreover, the optical center height ranged from 1 mm to 8mm and most common ranged (23%) were 4 mm. In other words, finished reading glasses have irregular optical ranges. After observing 200 people who are over 40 years old men and women, result shows that more than 75.5% (151 people) currently use finished reading glasses. Survey of 151 people, most common error between the finished reading glasses's O.C and the wearers P.D were 4 mm (45%). Furthermore, the most common error between the finished reading glassses's O.H and the wearers O.H ranged from 3 mm to 4 mm. Astonishingly, the entire 151 people who wear finished reading glasses appeal that they feel tiredness on their eyes when they wear finished reading glasses. 53 people (35%) claimed that they feel tiredness on their eyes after 10 to 20 minutes wearing finished reading glasses. Base on the research, We conducted more experiment to find the value of prism of optical centers err because it will tell us whether the finished reading glasses are good enough to wear or not. We multiplied diopter by the difference between finished reading glasses's O.C. and wearer's P.D. Consequently, We found out that the finished reading glasses counter to the German RAL-RG 915 policy. And We also found that it is relative to the diopter of lenses. In conclusion, based on the researched that wearing finished reading glasses have a dangerous factor for our vision. Therefore optician must need to recommend correctly made dispensing reading glasses based on the optical center point.

This study aims to suggest desirable directions through analyzing English test items of college entrance examinations(CEE) in Korea, China, and Japan. To achieve this, English test items of Scholastic Ability Test(SAT) in Korea were compared with those of CEE in China and Japan, and test items of TOEFL and IELTS. It was found that there were not many items for testing productive skills relatively to the tests of other countries including TOEFL and IELTS. Especially, there were integrated items for writing test in China. In case of speaking test, all the other country adopted direct ways like interview and oral test, not indirect test as in the SAT in Korea. It is suggested that there need to be included test items comprising long passages in order to measure extensive reading ability. It can be suggested that doze test be adopted for testing integrated proficiency of English.
