Purpose: Hook nail deformity is caused by inadequately supported nail bed due to loss of distal phalanx or lack of soft tissue, resulting in a claw-like nail form. A composite graft from the foot bencath the nail bed gives adequate restoration of tip pulp. Methods: From September of 1999 to March of 2004, six patients were treated for hook nail deformity and monitored for long term follow up. Donor sites were the lateral side of the big toe or instep area of the foot. We examined cosmetic appearance and nail hooking and sensory test. The curved nail was measured by the picture of before and after surgery. Results: In all cases, composite grafts were well taken, and hook nail deformities were corrected. The curved nail of the 4 patients after surgery were improved to average $28.7^{\circ}$ from average $55.2^{\circ}$ before surgery. The static two point discrimination average was 6.5mm and the moving two point discrimination average was 5.8mm in the sensory test. Conclusion: Composite graft taken from foot supports the nail bed with the tissue closely resembling the fingertip tissue, making it possible for anatomical and histological rebuilding of fingertip.

Purpose: Pincer nail is a relatively rare deformity characterized by an increase in transverse curvature along the longitudinal axis of the nail. This curvature commonly increases from proximal to distal end of nail, leading to pinching, curling, and distortion of the underlying soft tissue and resulting frequently in severe pain. Numerous surgical procedures have been reported. Preserving the width of the nail in the correction of the pincer nail is very important for functional and aesthetic reasons. We report the results of the correction of the pincer nail using autogenous dermofat graft with a good result. Methods: From May 2006 to September 2008, dermofat graft was performed in 6 patients with pincer nail. Patients were four women and two men, and the average age was 51. The affected digits were the unilateral great toes in four patients and the unilateral thumbs in two patients. Average follow-up period was 13 months. Surgical procedure was removal of nail using an elevator to avoid damage to the nail bed. An incision was created in distal portion of hyponychium. Paronychium was dissected from distal phalanx by periosteal elevator through incision of hyponychium and tunnel was made. Then dermofat grafts harvested from inguinal area were inserted into the tunnel. Finally, a silicone sheet was inserted eponychial fold for prevention of synechia. Objective assessment was evaluated by use of the width index and height index. Results: All patients reported resolution of the pain and soft tissue pinching sensation that they had before the operation. There was good adherence between the nail plate and the underlying nail bed. The nails have regrown and were corrected in a normal and flattened appearance. The width index and height index were improved. Conclusion: The autogenous dermofat graft seems to provide an effective treatment of the pincer nail with preservation of the nail matrix.

In this study, the bending behavior of cross-laminated timber (CLT) connected by nails were investigated. Especially, the load-carrying capacity of the nail-jointed CLT under out-of-plane bending was predicted by the lateral resistance of the used nails. Three-layer nail-jointed CLT specimens and a nail connection were manufactured by 30 mm (thickness) ${\times}$ 100 mm (width) domestic species (Pinus koraiensis) laminas and Ø$3.15{\times}82mm$ nails using a nail-gun. Shear test for evaluating the nail lateral resistance and bending test for evaluating the load-carrying capacity of the nail-jointed CLT under out-of-plane bending were carried out. As a result, two lateral resistance of the used nail, the 5% fastener offset value and the maximum value, were 913 N and 1,534 N, respectively. The predicted load-carrying capacity of the nail-jointed CLT by the 5% offset nail lateral resistance was similar to the yield points on the actual load-displacement curve of the nail-jointed CLT specimens. Meanwhile, the nail-jointed CLT specimens were not failed until the tension failure of the bottom laminas occurred beyond the maximum lateral resistance of the nails. Thus, the measured maximum load carrying capacities of the nail-jointed CLT specimens, approximately 12,865 N, were higher than the predicted values, 7,986 N, by the maximum nail lateral resistance. This indicates that the predicted load-carrying capacity can be used for designing a structural unit such as floor, wall and roof able to support vertical loads in a viewpoint of predicting the actual capacities more safely.

Nail-care services are growing rapidly. If causes for the increase in nail-care service consumption is diversion or self-satisfaction, we can speculate that consumers perform self-care through nail-care services. Nail-care-service consumption should be allowed to increase because of the positive psychological effects such as improving mood or alleviating depressed emotions. Moreover, the psychological effects of nail-care services differ according to consumers' tendencies. Therefore, this study divides the types of consumers, to investigate whether there is a difference in the psychological effects of nail-care services depending on the types. This study used the questionnaire survey method. Results of the study revealed that the sub-factors of self-esteem, extracted as two factors, were "personal self-esteem" and "social self-esteem". Consumers were classified according to the sub-factors of self-esteem into four groups. There were differences in the psychological effects of nail-care services according to these four groups. It was found that all groups had psychological effects above the average value. This result indicates that only the degrees of psychological effects differ in accordance with the types of self-esteem, and that psychological effects generally play a large role in all types. Since psychological effects were positive for everyone regardless of their self-esteem, utilizing nail-care services considerably reduces the depression and anxiety of modern people. Nail-care services expected to become the basis of the nail therapy field.
