絹織物加工을 實需要者의 利用度를 增加시키기 爲해 多年間 여러 사람에 의하여 硏究되어 왔으나 天然織維이기 때문에 加工方式으로 性質을 變化시키기는 어려워서 滿足스러운 精度로 이루어지지 못하고 있는 實情에 있다. 絹織物加工은 勿論 그 缺點을 補强하는 同時에 商品的價値도 向上시키는데 目的이 있는데 때로는 有名商標가 品質以上으로 販賣를 左右하는 例도 많다. 特히 絹制品은 歡迎을 받지 못하고 있는 實情에 있다. 이러한 問題點을 解決하기 爲해 筆者는 多年間 硏究를 持績하여 왔든바 一般絹織物의 浸潤後 乾燥時間보다 半減된 時間에 乾燥되는 所謂 Wash and Wear絹加工方法의 開發을 하기에 이르렀다. 그리고 그 加工費用이 極히 經濟性인 탓으로 아무런 부담감 없이 加工處理할 수 있는 特徵을 갖이고 있었다. 1. 繭絲는 吐絲營繭曲線이 S字型으로 되어 있어 浸潤時에는 原狀復舊의 性質이 있어 屈曲狀態를 이룩하게 되어 本加工絹織物이 Wash and Wear이기는 하나 가벼운 다림질이 必要하였다. 2. 이러한 加工은 絹絲蛋白質의 變性을 加工過程에서 1% D.I.S.溶液에 3時間 處理하여 變性誘發시킴으로서 可能하였다. 3. 加工絹의 防皺度, 剛乾度를 洗濯回數를 反復하면서 調査하여 본 結果 未處理絹보다 惡化되지 않았다. 4. 未加工絹도 水洗, 乾燥를 反復하게되면 스스로 變性되는 事實을 알았다. 5. 處理絹과 未處理絹의 强力伸度面의 差異가 없었다.

In this work, the surface integrity smoothened with a ball end mill was investigated. Because surface integrity mainly affects the manual finishing process, $RV_{AM}$(Remaining Volume After Machining) was introduced, and it gives the relation between machining process and finishing process. Runout and phase shift which adversely affect surface integrity were considered in the generation of surface topography. Cutting points in ball end milling were identified with positional vectors and a set of vectors which have the minimum height in unit area was selected for the generation of surface and $RV_{AM}$. $RV_{AM}$ variation according to runout and phase shift was calculated and experimentally verified in proposed HSM conditions for mold machining. From the simulations and the experiments, a desirable High Speed Machining condition was suggested.

In any form of construction work, it is essential that accidents be prevented at every stage from foundation preparation to build completion. For this, it is necessary to use models that can assess risk and provide instruction for safe work processes so that the risk of accidents is reduced. Currently, however, very few models can perform these tasks. In this paper, we presents a model that assesses risk quantitatively by analyzing risk factors involved in stage of construction such as foundation work, erection work, structural work, equipment work, finishing work and etc work. The model performs assessment based on examples of accidents and by investing actual conditions during construction. In addition, we presents in this paper a safety management system was developed to assess risk during construction and to effectively train laborers.

The procedure of predicting the construction cost and selecting the best alternative is performed based on comparative review of each building case. In the case of office building, it is required continuously until design is complete, since the owner requirements are various and likely to change during the design process compared to a standardized apartment. However, since the comparison work for each alternative in practice uses only the unit construction cost, there is no correlation between the alternative and the final result, and it is difficult to quantitatively determine the effect of the determined design factor on the total construction cost. It is needed that a means to support the generation of design alternatives using similar building cases during the design phase. This paper proposes a BIM-based data replacing process to support creating and comparison of design alternatives of internal finishing for office building. When design alternatives are created through the proposed process, it is possible to compare several similar cases with current project under equivalent design circumstance. Because only some finishing properties are replaced while maintaining the shape information such as the length, height, and base constraint of the object to be replaced.
