This paper proposes the soak time estimation method using the slope of control output in heat treatment process. The soak time is the time at which the center temperature of the steel and ambient temperature of the steel reach the target temperature. The center temperature of the steel is needed to find the soak time, but it is difficult to always measure because of the industrial furnace structure. By calculating the relation between soak time and control output, the proposed method can find the soak time using the control output, not the center temperature. To eliminate the noise generated by the Proportional-Integral-Differential controller (PID) controller and to calculate the smooth slope, the moving average filter was used. The proposed method was verified by comparing the estimated soak time and real soak time using the test data.

At times several complications can be encountered after laser resurfacing, even with careful preoperative screening and patient preparation as well as meticulous intraoperative technique. Hypertrophic scar is rare but the most severe complication, which e

Acquired periungual fibrokeratomas are rare, benign, fibrous and hyperkeratotic tumours. They usually present as lesions which emerge from the proximal nail fold, or sometimes from the nail bed. Although acquired periungual fibrokeratoma is considered as a topographical variant of acquired digital fibrokeratoma, it has a unique garlic-clove shape and causes nail deformity. We present herein a case of acquired periungual fibrokeratoma occurring beneath the proximal nail fold. Histologically, an accessory germinal matrix was observed at the distal end of the lesion. Change in pressure around the lesion seemed to have induced the formation of this accessory germinal matrix. (Korean J Dermatol 2003;41(8) : 1068~1071)

Bismuth layered structure ferroelectric thin films, $Bi_4$$Ti_3$$O_{12}$ / (BTO) and Nb-doped BTO (BTN) were prepared on the Pt(111)/Ti/$SiO_2$/Si(100) substrates by a sol-gel route. We investigated the Nb-doping effect on the grain orientation and ferroelectric properties. $Nb^{5+}$ ion substitution for $Ti^{4+}$ ion in perovskite layers of BTO decreased the degree of c-axis orientation and increased the remanent polarization (2Pr). The fatigue resistance of Nb-doped BTO thin film was shown to be superior to that of BTO, and the leakage current of Nb-doped BTO thin film was decreased about 1 order of magnitude compared with BTO. The improvement of ferroelectric properties with $Nb^{5+}$ doping in BTO could be attributed to the changes in space charge densities and grain orientation in the thin film.

Dermal melanocytosis is characterized by the presence of ectopic melanocytes in the dermis. Dermal melanocytosis assumes several morphologic forms, including the Mongolian spot, the blue nevus, the nevus of Ota, the nevus of Ito and dermal melanocytic ham
