The several computer programs for the design of soil nailed wall are often used in Korea. However, these programs have been used without and practical justification. Therefore, in order to evaluate the applicability of these programs for the design of soil nailing, these computer results were analyzed and compared with one another. The performance evaluations by the available programs, such as SNAILZ, TALREN97, SLOPE/W STABL6, and NAILMI6, were applied and the applied data were from 6 case history(21 section). The estimated factors of safety with available programs were compared with observed horizontal deformation from the field. This study showed that the program SNAILZ is most adequate tool for the design of soil nailed wall. Also, The finite element program SOILSTRUCT was applied for the analysis of nail inclination effect in soil nailed wall. The program SOILSTRUCT showed that the most optimal inclination of nail was $20^{\circ}$. However, the effect of nail inclination on the wall deformation was negligible. Also, the tension force of the nail were increased as the nail inclination increased, and the tension force of the nail increased as the depth increased, except the deepest nail. Therefore, the larger diameter nail should be considered if the inclination of nail is steeper than the suggested range, and the deeper nails should have the larger diameters than those of shallower nails except for the deepest one.

본 연구에서는 천경자 그림에 표현된 색채를 응용하여 추상적 네일디자인을 작품제작으로 표현하고자 한다. 이를 통해 네일 디자인의 창의적인 아이디어 발상에 대한 기본 토대를 마련하고 네일디자인의 표현영역을 확대하는데 목적을 가진다. 실증적 연구로서 천경자의 미술적 특징이 잘 표현된 작품 5가지를 선정하여 NCS 자연색체계를 활용하여 색채 데이터 분석을 하였으며, 색채 활용과 더불어 네일디자인을 표현하기 위해 천경자의 작품 속 대표되는 5가지의 모티프를 선정하여 각 작품에 표현하였다. 본 연구의 작품 제작에 나타난 디자인은 네일디자인과 현대 한국회화의 융 복합이며, 이를 통하여 뷰티디자인의 예술성을 다양한 시각으로 재창조하여 네일 디자인을 개발하였다.

본 논문의 목적은 네일리스트의 성숙도가 업무성과와 고객지향성에 미치는 영향에 관하여 실증적으로 검증하는 것으로 하였고, 전국에 있는 네일샵에 근무하는 성인 여성 네일 미용 종사자(네일리스트) 300명을 대상으로 분석을 하였다. 연구 가설을 규명한 결과, 네일리스트의 성숙도가 업무성과에 유의한 영향을 미친 것으로 나타났으며, 네일리스트의 성숙도가 고객지향성에도 유의한 영향을 미치는 것으로 나타났다. 이러한 연구 결과는 초보 네일리스트들이 점차 증가하고 있는 현 상황에서 네일리스트의 성숙도는 시술 결과나 매출적인 부분에서도 직접적으로 나타날 수 있기 떄문에 네일리스트의 성숙도에 대한 개선 방안은 고객지향성이나 업무성과에 밀접한 영향을 줄 것으로 사료된다. 성숙도가 네일 미용이나 다른 미용(피부, 헤어 등)의 관점에서 연구된 선행 연구가 많이 부족하여 논의에 어려움이 많았기에 향후에는 좀 더 심층적인 후속 연구가 진행되기를 기대한다.

Soil nailing technique is being widely used for stabilization of vertical cuts because of its economic, environment friendly and speedy construction. Global stability and lateral displacement are the two important stability criteria for the soil nail walls. The primary objective of the present study is to evaluate soil nail wall stability criteria under the influence of in-situ soil variability. Finite element based numerical experiments are performed in accordance with the methodology of $2^3$ factorial design of experiments. Based on the analysis of the observations from numerical experiments, two regression models are developed, and used for reliability analyses of global stability and lateral displacement of the soil nail wall. A 10 m high prototype soil nail wall is considered for better understanding and to highlight the practical implications of the present study. Based on the study, lateral displacements beyond 0.10% of vertical wall height and variability of in-situ soil parameters are found to be critical from the stability criteria considerations of the soil nail wall.

Double-sided punched metal plate timber fasteners present projections on both sides, which offer improved joint fire resistance and better joint aesthetics. In this paper, 3-D nonlinear finite element models were developed to simulate double-sided nail plate fastener timber joints. The models, incorporating orthotropic elasticity, Hill's yield criterion and elasto-plasticity and contact algorithms, are capable of simulating complex contact between the tooth and the timber and between the base plate and the timber in a fastener. Using validated models, parametric studies of the double-sided nail plate joints was undertaken to cover the tooth length and the tooth width. Optimal configuration was assumed to have been attained when increase in nail plate tooth width did not result in a raise in joint capacity, in conjunction with the optimum tooth length. This paper presents the first attempt to model and optimise tooth profile of double-sided nail plate fastener timber joints, which offers rational designs of such fasteners.

Onycholysis is defined as a distal or distal lateral separation of the nail plate from the underlying or lateral supporting structures including nail bed, hyponychium, and lateral nail fold. Trauma, infection, psoriasis, thyrotoxicosis, and numerous drugs are common causes of onycholysis. However, there are few specific data on nail findings in Behcet's disease (BD). In this paper, we report on a 60-year-old man with BD, with no past history except BD, who developed recurrent onycholysis. The symptoms of onycholysis are considered to be recurrent depending on the activity of BD. The nail lesion showed improvement after classic treatment of BD and topical steroid ointment.

A new method of estimating axial nail force is proposed. An instrumented soil nail wall is selected to investigate the effectiveness of the new proposed method. The new method includes effect of creep and age of cement grout surrounding the steel bar, The new method also considers cracks in the grout generated during and after the end of the wall construction. It is found from this study that a reduced grout stiffness due to creep with age and crack of the grout must be considered for estimating correct axial nail forces. The reduced grout stiffness is considered also providing significant part of axial nail load compared to that of steel bar.

Soil nailing method is widely used in reinforcing slopes and excavating earth. The analysis of nail-reinforced slopes, in order to determine the economical length ratio and nail angle, complicated analytical need to be applied by means of computer programs. Therefor this suggested Soil stability Chart for nailed slopes which may be very useful for pre-design, rapidly design, and final check. Three slope types, three nail length and three nail angles are selected for the stability analysis by using limit equilibrium method of Bishop and French Method. From the above results, this study propose the slope reinforced design charts for dry season and rainy season. This proposed reinforced design charts can check dry season as well as rainy season, also these charts can provide reinforcing requirement, soil nail's economical length ratio and nail angle as well.
