This study examines the development of knitwear design using environmentally friendly Hanji (Korean traditional handmade paper) yarn. While its environmentally friendly features make Hanji yarn suitable for eco-fashion design, Hanji products, generally produced in limited quantities, are highly unlikely to become a commercial success due to their high prices. Therefore, a new technology allowing the production of low-cost Hanji yarn is in high demand, as is its application across multiple products in addition to knitwear. The significance of this study lies in that it suggests ways to design knitwear which reflect the versatility of modern eco-fashion to meet the needs of consumers. This study presents knitwear designs, specifically party wear and everyday fashion, that utilize the advantages of Hanji yarn and represent 2013 S/S color trends. Two outfits will be featured - one for women in their 20s and 30s and the other for women in their 30s and 40s. Also, this paper includes a literature review and an accounting of online research on Hanji yarn and eco-fashion designs.

Steel reinforced concrete is perhaps the most versatile and widely used construction material. The versatility is attributed to mouldability of concrete to any conceivable shape. The inherent property of cracking of concrete is the reason for its low tensile strength and hence the design approach of RCC sections in flexure adopts the cracked section theory where in concrete in tension zone is ignored. Means, modes and methods of exploitation of concrete strength by conceiving shapes other than rectangular whereby ineffective concrete in tension zone is reduced and incorporated in compression zone where it is effective needs consideration. Shape optimization of beams is attempted in this analytical investigation employing Sequential Unconstrained Minimization Technique (SUMT). The results clearly show that trapezoidal beams happen to be less costlier than their rectangular counterparts, their usage needs serious reconsideration by the designers.

A novel set of experimental test tooling for measuring pulling and holding forces for drawbeads on binders inclined at a wide range of angles is introduced. A mechanical design featuring a single load cell, a male-female draw bead set, translation and rotation degrees of freedom, and a screw-driven clamping system has been incorporated into a standard tensile test machine. On a real time basis, restraining and holding force data with respect to draw-in displacement may be directly downloaded into a PC for data processing. The proposed experimental system represents a significant breakthrough in drawbead simulation technology due to its relatively low cost, clever design, and versatility. The system is shown to yield excellent experimental data suitable for verifying theory and numerical model predictions.

Recently designed residence complexes, there is an increasing interest in qualitative and quantitative improvement of not only the primary function of the residence, but also the community facilities designed for the convenience and welfare of its residents. Among such community facilities, an apartment's playground for children still remains in a traditional form and lacks the versatility required to satisfy the needs and interests of modern children, especially an age diverse child population. Therefore, this study intends to analyze the status of children's play facilities as community spaces, analyze the community's satisfaction with them, and suggest alternatives to the limited functions of children's play facilities in order to improve opportunities for neighbors to meet and build a stronger community.

최근 도시지역의 홍수방지 및 지정체 반복구간의 교통문제 해결을 위해 다목적 대심도 복층터널의 건설이 요구되고 있다. 다목적 복층터널은 주기능인 도로기능 이외에 다목적 기능을 부여해 지하공간의 효율적인 활용을 위해 도입이 절실하다. 본 연구에서는 도심지 치수능력 증진과 도로터널의 기능을 동시에 고려하기 위한 입지선정 조건과 복층터널의 단면 구역별 처리가능한 유량에 대한 기초검토를 수행하였다. 터널의 용도별 입지선정 기준 검토를 통해 복층터널의 다목적 활용을 위한 입지선정 기준 방안을 제시하고 있다. 또한 대심도 복층터널의 다목적 활용성 검토를 위해 계획단면에 대한 홍수시 처리 가능 유량을 검토하였다. 본 연구로부터 복층터널의 입지선정은 다양한 분석을 통한 복합적인 고려가 필요함을 알 수 있다.

This study is targeted on children's parks in Seogu, Daejeon with the goal of maximizing the usage and versatility of existing parks in the area by the survey and analysis of the general status of children's parks, land use near the parks, population, users, and traits of usage. For the purposes of this thesis this study has selected 65 of the children's parks in the Seogu District to monitor. It also focused on a number of these parks located in areas which underwent a lot of changes and needed an increase in usage and versatility. Based on the selection criteria, the four target parks, Wojeong, Meongwhack, Dosan and Wicdunjimi children's park were selected. The Survey shows that 55.9% of park visitors visited a park to 'rest and take a walk' and used 'main facilities' meaning resting facilities like pergola and benches. In the nighttime, the number of park visitors is so few because of safety problems. 50% of users were satisfied with parks. It shows that there are many respondents who want to recompose these parks as places for light exercise, resting, meeting, and as community symbols. Generally, these target parks don't reach their full potential and they also do not play their proper roles because they are hampered by the constriction of the law. These stick to an outdated idea of what a park should be like without considering the actual and practical needs of city dwellers. When it comes to the remodeling and refurbishing of these parks we have to rethink the planning process so that these parks may be more versatile and practical in order to accommodate the radical changes of users and patterns of usage.

Pseudo dynamic test is an on-line computer control method to achieve the realism of shaking table test with the economy and versatility of the conventional quasi-static approach Pseudo dynamic tests of six full-size RC bridge piers have been carried out to investigate their seismic performance. For the purpose of precise evaluation, the experimental investigation was conducted to study the seismic performance of the real size specimen, which is constructed for highway bridge piers in Korean peninsula. Since it is believed that Korea belongs to the moderate seismicity region, five test specimens were designed in accordance with limited ductility design concept. Another one test specimen was nonseismically designed according to a conventional code. Important test parameters were transverse reinforcement and lap splicing. Lap splicing was frequently used in the plastic hinge region of many bridge columns. Furthermore, the seismic design code is not present about lap splice in Korean Roadway Bridge Design Code. The results show that specimens designed according to the limited ductility design concept exhibit higher seismic resistance. Specimens with longitudinal steel lap splice in the plastic hinge region appeared to significantly fail at low ductility level.

End milling is an important and common machining operation because of its versatility and capability to produce various profiles and curved surfaces. This paper presents an experimental study of the cutting force variations in the end milling of SM25C with HSS(high speed steel) and carbide tool. This paper involves a study of the Taguchi design application to optimize cutting force in a end milling operation. The Taguchi design is an efficient and effective experimental method in which a response variable can be optimized, given various control and noise factors, using fewer resources than a factorial design. This study included feed rate, spindle speed and depth of cut as control factors, and the noise factors were different cutting tool in the same specification. An orthogonal array of $L_9(3^3)$ of ANOVA analyses were carried out to identify the significant factors affecting cutting force, and the optimal cutting combination was determined by seeking the best cutting force and signal-to-noise ratio. Finally, confirmation tests verified that the Taguchi design was successful in optimizing end milling parameters for cutting force.
