The characteristics of Korean women's foot shape were extracted by analyzing foot measurements. 14 measurements were measured from foot outline and 12 conventional measurements were taken on the right foot of 386 Korean women from 18 to 86 years. The results indicate that women's foot shape is changed with aging. The young subjects' feet were longer than the foot length of older subjects. The metamorphosis angle of the women over age 45 was greater than the measurement of women under age 45. The typical Korean women's foot shapes characterized by cluster analysis were (1) small foot with little deformity on great toe, (2) wide foot with big deformity on great toe, and (3) thick and narrow foot with moderate deformity on great toe. These results indicate that the foot height and the degree of deformity on great toe are needed to be considered in developing the shoe last for Korean women. The specialized shoe last needs to be developed for elderly.

Stress fractures of the proximal phalanx of the great toe are rare. This fractures have been associated with halux valgus deformity in most reports. We performed open reduction and internal fixation with distal chevron osteotomy for the stress fracture of the proximal phalanx of the great toe in a basketball player with hallux valgus, and obtained successful bony union and rapid return to sports.

현재 네트워크 기술은 기가비트급의 속도를 넘어 급속히 발전하고 있다. 이러한 고속 네트워크상에서 TCP/IP를 사용할 경우, 호스트 CPU에서 TCP/IP 프로토콜을 처리하는데 많은 부하가 발생한다. 이러한 문제를 해결하기 위해 최근 네트워크 어댑터에서 TCP/IP를 처리하는 TCP/IP Offload Engine(TOE)에 대한 연구가 활발히 진행되고 있다. 본 논문에서는 임베디드 시스템과 리눅스를 사용하여 TOE를 구현하였으며, 그 동작 메커니즘을 보인다. 실험 결과 및 분석을 통해 임베디드 시스템에 리눅스를 활용한 TOE는 상당한 오버헤드를 가지고 있는 것으로 나타났으며, 이를 바탕으로 추후 기가비트 환경에 맞는 TOE 구현시 이러한 오버헤드를 극복할 수 있는 방안을 제안한다.

Stream servers are for supplying multimedia stream data to users through the internet such as movies and musics without discontinuation. A typical stream server is designed roughly by considering the characteristics of stream services and by employing processors, memory, PCI bus, Ethernet, TOE and disks. This study focuses on deciding the priority for using resources such as PCI bus, buffer memory and TOE buffer, which have limited capacities in a typical stream server. The simulation study shows that the top priority for using PCI bus for normal streaming services should be given to the operation that sends data from buffer memory to TOE buffer Giving priority for using PCI bus to other operation such as sending data from disks to memory results in deadlock Phenomenon.

This paper is concerned with the mutual relationship among interpressure, last. foot within a new shoe and foot within a fifty-hour-used shoe at the standing posture at three different heel-heights 1. The interrelationship between the heel-heights and interpressure is very significant at the level of $0.1\%$. The heel-heights cause high interpressure at different parts of foot; heel point and big toe point in a 3 cm-heel shoe, big toe point and heel outside joint point in a 5 cm-heel shoe, and little toe point, heel-outside joint point, and arch point in a 7 cm-heel shoe. 2. Foot girth and foot width measurements either within a new shoe or within a fifty-hour-used shoe significant at the level of $5\%,\;1\%,\;0.1\%$ and show discrepancies at three different heel heights; the part between instep and ball joint in a 3 cm-heel shoe, toe part in a 5 cm-heel shoe, heel-inside joint. heel-outside joint and toe part in a 7 cm-heel shoe are highly influenced by heel heights. The higher the shoe-hee15 are, the more heavily the fore part of foot is pressured in lateral direction because shoe is made to have high instep from a fashion viewpoint. Higher shoe heels prevent weight pressure from being concentrated on heel. If shoe heels are toe high, people in such shoes feel easily tired. It is very worthy of note in selecting shoes to consider not only the shoe fashion but also fore shoe type, heel height, and shoe material with proper elasticity.

Background The introduction of the partial second toe pulp free flap has enabled superior aesthetic and functional results for fingertip reconstruction in adults. Children undergoing fingertip amputation for various reasons have limited options for reconstruction. Conventional treatment could shorten the finger, leading to poor cosmesis and function. We report 18 years of our experiences with fingertip reconstruction using partial second toe pulp free flaps in patients in early childhood. Methods Medical charts of children who had undergone fingertip reconstruction using partial second toe pulp free flaps from 2001 to 2018 were retrospectively reviewed. The surgical procedures were identical to those for adults, except for the usage of 11-0 nylon sutures. Patients' demographic data, vessel size, flap dimensions, length of the distal phalanx, and functional outcomes over the course of long-term follow-up were documented. The statistical analysis was performed with the Student t-test, the Mann-Whitney U test, and Pearson correlation analysis. Results Eighteen toe pulp flaps in 17 patients (mean age, 3.0 years) were identified. All the flaps survived without any major complications. In long-term follow-up, the flap-covered distal phalanges showed growth in line with regular development. There was no donor-site morbidity, and all children adapted to daily life without any problems. In two-point discrimination tests, the fingertip sensation recovered to almost the same level as that in the contralateral finger. Conclusions Partial second toe pulp free flaps are an excellent option for fingertip reconstruction in young children, as well as in adults.

TCP/IP, the most popular communication protocol, is processed on a host CPU in traditional computer systems and this imposes enormous loads on the host CPU. Recently TCP/IP Offload Engine (TOE) technology, which processes TCP/IP on a network adapter instead of the host CPU, becomes an important way to solve the problem. In this paper we analysed the structure of a TCP/IP protocol stack in the Linux operating system and important factors, which cause a lot of loads on the host CPU, by measuring the time spent on processing each function in the protocol stack. Based on these analyses, we propose a Hybrid TOE architecture, in which functions imposing much loads on the host CPU are implemented using hardware and other functions are implemented using software.

Purpose: The second toe PIP joint free flap is a method of reconstruction used for abnormalities of the PIP joint of the finger. We report the results of the additional tenolysis in patients with a difference between passive ROM and active ROM after second toe PIP joint free flap. Methods: From March 2001 to July 2008, tenolysis was performed in patients with a difference in their active and passive ROM after second toe PIP joint free transfer, performed on 14 fingers. We performed a retrospective analysis of the medical records, noting the clinical and radiological findings. In addition, we measured the preoperative and postoperative range of motion of the PIP joint. Results: The average active ROM was $22.5^{\circ}$ at the three months after the joint transfer surgery, and was $38^{\circ}$ after additional tenolysis between five months and twelve months after the joint transfer. Conclusions: Additional tenolysis, after the second toe PIP joint free flap, might be a good option for improved results in patients with difference in active and passive ROM of a transferred PIP joint.

There was extreme improvement in the processing result of weld toe, but there is possibility that the fatigue failure occurs from the weld root part where the fatigue strength became low relatively. This study did the fatigue test at the cross rib specimens which implemented a partial penetration weld to improve the fatigue strength of the weld root part. As a result of the fatigue test of the partial penetration weld and the fillet weld specimens, almost the same fatigue strength appeared. Because the fatigue failure began from toe, there was not a reinforcement effect in the weld root part by the partial penetration weld. So, it examined fatigue strength at the partial penetration welding specimens which processed toe to stop the fatigue failure of toe part. As a result, there was big fatigue strength improvement from the partial penetration weld than the fillet weld. Therefore, if fatigue crack occurrence can be restrained from toe, it thinks that the fatigue strength of the root part can improve by the partial penetration weld, after all, it thinks that the overall fatigue life can improve.
