The purpose of this study is to demonstrate the improvement of the education process in architectural engineering through the analysis of the advantages of the BIM tool. As public institutions and owners have been introduced to Building Information Modeling (BIM) tools, BIM has become an important factor in the design process in undergraduate university programs. First, BIM-related issues, domestic and overseas, was analyzed. Second, a case study of BIM education was analyzed at K University under the ABEEK process. Students participated a survey about the understanding of BIM and the use of BIM tools. As a result of the analysis, six advantages of the use of BIM tools were found. As a result of this research, following five issues are found about BIM education through advantage of using BIM tools. The result of this research was verified by conducting a survey on the usage of BIM softwares. The limitation of this study was to analyze the case study of only limited numbers of participants at the university.

TFormic acid-hydrogen peroxide (or performic acid) pulping process needs milder reaction condition than other chemical pulping process. Two-step formic acid-hydrogen peroxide pulping process can produce the chemical pulp with similar pulp yield and lignin content compared with soda-anthraquinone process. Formic acid-hydrogen peroxide pulp can be produced less xylan content than other alkaline pulps, which favor for dissolving pulp production. Formic acid-hydrogen peroxide pulp showed better response beating than soda-anthraquinone(AQ) pulps with reaching target freeness with less beating. Also, formic acid-hydrogen peroxide pulp had better tensile index at similar freeness level compared with soda-AQ pulps.

Recently, interest in utilization plan of recycling paper have been enhanced. Therefore, this research aimed to develop the manufacture process of cellulose acetate using old newsprint by acetosolv pulping process. And the manufactured cellulose acetate was also analyzed, especially based on chemical properties. The summarized results in this research were as follows; Reaction time, kind and amount of catalyst, and ratio of liquor to material were varied during acetosolv pulping process of old newsprint. Ratio of liquor to material did not give the significant difference in reaction product. Delignification rate was increased with increasing reaction time during acetosolv pulping, but yield and degree of substitution decreased with increasing reaction time. Sulfuric acid are better catalyst than hydrochloric acid in acetosolv pulping process for old newsprint, and optimal addition amount of catalyst was 1% based on reaction material. Delignification, yield, and degree of substitution were influenced by the catalyst and reaction time. Under pulping condition of $120^{\circ}C$ in 1/12 liquor to material ratio and 60min, degree of substitution was about 0.7. The acetylation reaction was not completely caused by these reaction condition. The examination of the FT-IR spectra revealed that absorption band(1200$\textrm{cm}^{-2}$, 1,750$\textrm{cm}^{-1}$) caused by carbonyl group were confirmed.

As far as we handle industrial products, the painting process is prerequisite; and the preparatory treatment of materials is, therefore, indispensable to the above process. However, it is a matter for regret that people are liable to overlook the importance the treatment of materials at the preparatory stage, giving themselves up to the surface of finished goods. The preparatory treatment of materials is like backstage personnel (operations) in dramatic performance; the performance cannot be successful without the support of backstage operations in surface treatment. The various methods which are being applied widely as preparatory treatment are as follow: (1) the method by using hand tools such as grinders, etc. (2) the method with blasting (3) the method with chemical coating (4) the method by getting rid of fatty substance with organic solvent The methods No. 1 and No. 2 are in use mainly for larger structures, and those No. 3 and No. 4, either singly or combined, are applied for mass-produced, smaller items (acid cleaning is applied for getting rid of rust, as the case may be). The method No. 3 is used mainly as anti-rust by forming zinc phosphate film on the surface of steel plate or enhancing the bonding power of paints by taking advantage of irregular surfaces of films. Recently are no the market steel plates treated directly with film-coating by omitting the process No. 3. Furthermore, those goods painted include not only nonferrous goods but plastics and elastomer. The present discourse describes the cleaning process by using the steam of organic acid, picked up from among No. 4, and its equipment applied.

The current 3D CG animation pipe line, which is the production system, does not have an effective solution that all animation departments are able to start their jobs independently against other animation departments. It is generally acknowledged that we could not do animating task before the modeling and set-up task. This kind of process has caused loss of labour. We could expect lasting problems which is stopping marking animating process before the previous process done again in case of requiring editing the jobs which are modeling and set-up. We could solve these "bottleneck" situation with "master character" defined as standard, so that animate and retake the job independently against other departments. These new process could accelerate the animation pipe line system.

This paper attempts to construct a storytelling model of computer games by using the Greimas's schema of narrative. Analysis target is multi-play of Starcraft, which has the non-linearity and interactivity. As a result, the process of manipulation and sanction, occurred in epistemological level at very short time and the process of competence had lots of small schema of narratives and repeated that small narratives. This model may be applied to other games, because it looks that most of games have very short process of manipulation and sanction at epistemological level and have long process of competence as main game play.

For teaching Advertisement Drawings practically, knowledge of Outdoor Advertisement Practice must be ahead of drawing practices. For understanding and practicing of various materials, treatments, manufacturing process and arrangement on drawings, it is desirable understanding outdoor manufacturing process, and making use of a mock-up. Actually, technical books about outdoor advertisement are very insufficient. As a teaching media based on the actual field for advertisement drawings, snapshots of the field and actual process and a mock-up of a signboard was prepared for practical application.

The purpose of this study is to identify variables that influence the family decision-making process when planning a wedding. In this case the planning refers to: the procedure of the wedding: yedan, which means presents for parents and relatives: and yemul, which means wedding gifts. Decision-making was categorized into four types: decisions led by the bride and groom, decisions led by the groom's parents, decisions led by the bride's parents, and co-decisions by the two families. Resource theory was used as a conceptual framework. Data for this study were collected from 305 adults who got married after 1977 and lived in Seoul. Multinomial logistic regression models were used to analyze the data. Variables determining the decision-making of wedding procedure were the groom's age at marriage, the level of familism, and the major source for the wedding expenses. When it came to decisions on yedan, gender, the bride's year of education, and the major source for wedding expenses had significant influence on the decision-making. Variables that affected decision-making on yemul were the bride's year of education, and the major source for wedding expenses. This study suggested the power structure among bride, groom, and their parents through variables which exert influence on family decision-making.

Accelerating economic growth since the 1960s, penetration rate of the House of Commons has been increased. However, design competition has been imposed for improve of the qualitative level in modern because it was quantitative increasing. Even though its design quality is improved by introducing design competition, distorting the design is increased for the purpose of election. For that reason, errors of information and design changes are increased. So BIM(Building Information Modeling) is adopted to solve the problems. In this study, BIM process on the basis of the existing design process was to clean up and LoI(Level Of Information) based on the level of information was newly defined. Working-level of the design competition is plan-basic design. LOI level is LOI1-LOI2 in plan and Lol3-LOI4 in basic design. At each step of the operation was to clean up the level of detail and content. Also exchange of data in each area and feedback about content are to clean up.
