  • Various surgical procedures have been described for treating osmidrosis axillare. Elimination of the apocrine glands is prime goal. Optimal operative procedure is characterized as follows: minimal axillary scar(which has cosmetic merits), less complications such as hematoma and seroma, short and less painful recuperating period, minimal damage to the skin and low recurrence rate. Three types of incision technique in subdermal shaving method have beeb commoly used. First, single incision method has an advantage of minimal scarring but more recurrence due to incomplete removal of apocrine glands may occur. Second, double incision technique(Bipedicled flap) has advantages of complete excision, low recurrence rate and relatively minimal scarring, but it could cause frequent necrosis of skin and folding of skin flap. Skoog's method is the third method, which makes four flaps by offset cruciate incisions. It is a better technique in aspect of complete excision of apocrine glands and low recurrence rate but has disadvantages such as development of hypertrophic scar or scar contracture in the line that lies perpendicular to natural axillary skin crease. We used a modified procedure which has shorter length in vertical and transverse incision compared with the classic Skoog's method. We dissected further subcutaneous tissue through the diamond-shaped incision and utilize wide operation field that provide adequate excision of subdermal tissue and proper hemostasis. Between 1999 and 2004, we operated 160 osmidrosis axillare in 80 patients in this technique. Most patients obtained satisfactory result with very low complications. Hematoma or seroma 3.1% Infection 0.6% Partial wound disruption 10% Recurrence 1.2%. Modified Skoog's method for treating osmidrosis axillae could be a optimal technique providing wide operation field for adequate excision of apocrine glands and proper hemostasis and leaving relatively inconspicuous scar and low incidence of scar contracture.

  • Background: $Abb{\acute{e}}$ flap technique is one of the most challenging operations to correct horizontal deficiencies in secondary cleft lip deformity. Since its first introduction, the operative method was dynamically modified from simple variation to complete conceptual change, but conventional $Abb{\acute{e}}$ flap has many drawbacks in esthetic and functional aspect. Our purpose was reconstructing the symmetry of Cupid's bow and central vermilion tubercle with minimal sequalae. Methods: From 2008 to 2016, this technique was applied to 16 secondary cleft lip patients who had total or more than 60% of unilateral deficiency of Cupid's bow and central lip or tubercle pouting deficiency. A quadrangular-shaped flap was transferred from vermilion including skin and white line of central or contralateral lower lip. Pedicle division and insetting were made at 9 (unilateral) or 10 (bilateral) days after transfer. Secondary lip revision was done with open rhinoplasty after wound maturation. Results: Overall satisfaction was high with modified technique. Scar was minimally noticeable on both upper and lower lip especially. Balanced Cupid's bow and symmetric vermilion tubercle were made with relatively small size of flap compared to conventional $Abb{\acute{e}}$ flap. An accompanying benefit was reduced ectropion of lower lip, which made balanced upper and lower lip protrusion with more favorable profile. Conclusion: A new modified $Abb{\acute{e}}$ flap technique showed great satisfaction. It is worth considering in secondary cleft lip patient who has central lip shortage and asymmetry of upper lip vermilion border line. Our technique is one of the substitutes for correction of horizontal and central lip deficiency with asymmetric Cupid's bow.

  • Background This study evaluated the outcomes of a new modified Wies technique for patients with involutional lower eyelid entropion without horizontal eyelid laxity. Methods This case series retrospectively analyzed consecutive patients with entropion who underwent surgery between January 2014 and March 2019 by the same experienced surgeon. Horizontal eyelid laxity, lower eyelid retractor function, and orbicularis muscle overriding were recorded before and after surgery. The recurrence rate and complications were also evaluated. This technique consisted of modified everting sutures combined with reattachment of the lower eyelid retractors to the inferior tarsal plate. Results This new technique was performed on 28 eyes in 25 patients (mean age, 71.0±8.0 years; range, 56-87 years). Nine patients (36%) were women and 16 (64%) were men. Lower lid entropion was present in the right eye in 14 patients (56%), the left eye in eight patients (32%), and both eyes in three patients (12%). The mean follow-up period was 27.3±12.4 months (range, 6-60 months). No intraoperative complications were observed. All patients' symptoms were alleviated. One patient (3.6%) had recurrence after 2 years (success rate, 96.4%). The remaining 27 eyes maintained a satisfactory and comfortable eyelid position. No patients had problems with scarring. Conclusions The approach described herein proved to be safe and feasible in eyes with involutional lower eyelid entropion without horizontal eyelid laxity. These advantages of this procedure include the lack of a conjunctival scar, punctal eversion, and lateral canthal angle deformation. A low recurrence rate and a long interval to recurrence were also observed.

  • Although somatic cell nuclear transfer (SCNT) is frequently employed to produce cloned animals in laboratories, this technique is expensive and inefficient. Therefore, the handmade cloning (HMC) technique has been suggested to simplify and advance the cloning process, however, HMC wastes many oocytes and leads to mitochondrial heteroplasmy. To solve these problems, we propose a modified handmade cloning (mHMC) technique that uses simple laboratory equipment, i.e., a Pasteur pipette and an alcohol lamp, applying it to porcine embryo cloning. To validate the application of mHMC to pig cloning, embryos produced through SCNT and mHMC are compared using multiple methods, such as enucleation efficiency, oxidative stress, embryo developmental competence, and gene expression. The results show no significant differences between techniques except in the enucleation efficiency. The 8-cell and 16-cell embryo developmental competence and Oct4 expression levels exhibit significant differences. However, the blastocyst rate is not significantly different between mHMC and SCNT. This study verifies that cloned embryos derived from the two techniques exhibit similar generation and developmental competence. Thus, we suggest that mHMC could replace SCNT for simpler and cheaper porcine cloning.

  • In this paper, we propose a modified proximal point algorithm which consists of a resolvent operator technique step followed by a generalized projection onto a moving half-space for approximating a solution of a variational inclusion involving a maximal monotone mapping and a monotone, bounded and continuous operator in Banach spaces. The weak convergence of the iterative sequence generated by the algorithm is also proved.

  • A five-day old female Thoroughbred foal appealed mild edema and pain of a lower eyelid on left eye. She was diagnosed with a typical entropion which clinical signs were inward rolling of the eyelid edge and excess lacrimation. Modified Hotz-Celsus technique that resect and suture only skin was operated. Result was very successful without recurrence of entropion and other complications. We conclude this method is of value for permanent correction of severe entropion in young foals.

  • This paper presents an alternative technique for DOA (direction-of-arrival) estimation. For generating a weight vector orthogonal to the signal subspace, a modified version of MES (minimum eigenvalue searching ) method is introduced. The performance of the proposed technique is compared to that of the conventional ED (eigen decomposition) method in terms of angle resolution for a number of snapshots during agiven observation period as well as various SNR's. In addition, the superiority of the suggested technique is shown, by analyzing the required computational load of the proposed MES and conventional ED method. A novel procedure of simplifying the MES proposed in [1] is presented on that purpose. Another advnatage of the proposed technique is that it is performed independently of the detection of the number of signal components, which makes it possible to estimate the DOA's of clusters consisting of infinite number of inseparable signal components.

  • A Digital Wave Tank simulation technique, based on a finite-difference method and a modified marker-and-cell (MAC) algorithm, is applied in order to investigate the characteristics of nonlinear Tsunami propagations and their interactions with a 2D sloping beach, Ohkushiri Island, and to predict maximum wove run-up around the island. The Navier-Stokes (NS) and continuity equation are governed in the computational domain, and the boundary values are updated at each time step, by a finite-difference time-marching scheme in the frame of the rectangular coordinate system. The fully nonlinear, kinematic, free-surface condition is satisfied by the modified marker-density function technique. The near shore Tsunami is assumed to be a solitary wave, and is generated from the numerical wave-maker in the developed Digital Wave Tank. The simulation results are compared with the experiments and other numerical methods, based on the shallow-water wave theory.
