Morphological and genetic variation of two populations of Platichthys stellatus were investigated based on 30 individuals each, collected from Uljin (seedling release area) and Pohang (control) in Korea. Morphological analyses demonstrated that the two populations of P. stellatus were well distinguishable in body color of the blind side and fin shape. Mitochondrial DNA control region analysis indicated no significant differences between the two populations ($F_{ST}=-0.00849$, P>0.05). We also analyzed microsatellite DNA loci of the two populations using six markers. Observed heterozygosity ($H_O$) and expected heterozygosity ($H_E$) were 0.550 and 0.592, respectively, in P. stellatus from Uljin, but 0.700 and 0.737 in P. stellatus from Pohang. An index of differentiation in genetic structure revealed significant differences between the two populations ($F_{ST}=0.0208$, P<0.05). Our results suggest that the Uljin population may be comprised of released P. stellatus, whereas the Pohang population may be wild P. stellatus, highlighting the necessity of continuous monitoring of the two populations.

Developmental pulmonary abnormalities are known as rare condition. diagnosis was made at autopsy in the early cases reported, however, as diagnostic aids such as X-ray, bronchography, bronchoscopy and exploratory thoracotomy have come into use, the condition is being discovered more often recently in living persons, and it appears to occur with sufficient frequency to merit consideration in the differential diagnosis of certain chest conditions. According to Schneider and Boyden there are three main types of this abnormality: [1] Agenesis, in which there is complete absence of one or both lungs; there is no trace of bronchial or vascular supply or of parenchymal tissue. [2] Aplasia, in which there is suppression of all but a rudimentary bronchus which ends in a blind pouch; there are no vessels or parenchyma. [3] Hypoplasia, in which the bronchus is fully formed but is reduced in size and ends in a _ flesh structure which usually lies within the mediastinum. Rudimentary pulmonary parenchyma may be present around the bronchial stump and often is the site of cystic malformation. We experienced one case of hypoplastic lung with cystic malformation which was originated from a small aberrant rudimentary bronchus, and the rudimentary bronchus was branched from the right side of tracheal end. The diagnosis was finally confirmed by the histopathological finding. Now, we report this case with a brief review of literatures.

Objective: The purpose of this study was to investigate the efficacy and safety of spinal-Z, derived from Peganum harmala seeds and Dracocephalum Kotschyi Boiss leaves, in patients with esophageal and stomach adenocarcinoma, and squamous cell carcinoma of the esophagus. Methods: Sixty-one patients with malignancies of the upper gastrointestinal tract were randomly assigned to one of two groups (treatment or control) in a double-blind fashion. Six capsules of Spinal-Z were prescribed to the patients with the regimen of 600 mg/m2/day, and placebo to the control group, for six months. Results: There were no significant differences between the two groups with regard to age, sex, duration of cancer, type of cancer and family history of cancer. There were significant differences in abdominal pain, heartburn, constipation and vomiting between the two groups, following spinal-Z therapy. Evaluation of drug side effects showed no difference in cough or other respiratory symptoms, itching, headache or dizziness between the two groups, both before and after treatment. Conclusion: This study indicates that Spinal-Z is safe and efficacious in the management of patients with upper gastrointestinal tract cancers.

Purpose: In the study effects of San-Yin-Jiao (SP6) acupressure on anxiety and pulse during labor, and on neonatal status were examined. Method: The design was a randomized controlled clinical trial with a double-blind method. Data were collected before (pre) and after (post) treatment using structured questionnaire, anxiety scale, pulse rate, umbilical vein pH and Apgar scores. The experimental group received SP6 acupressure for the duration of each uterine contraction over a period of 30 minutes, but the control group received SP6 touch. Results: The anxiety scores between the two groups increased, but the increase was less in the SP6 acupressure group and the difference was statistically significant (p=0.019). Maternal pulse rate was not significantly different immediately after treatment (p=0.711), at 30 and at 60 minutes (p=0.140 ; p=0.108), but while the SP6 acupressure group had a stable pulse, the SP6 touch group showed an increased rate. There was no significant difference between the two groups for umbilical vein pH (p=0.124), and neonatal Apgar score at one and five minutes (p=0.387 ; p=0.979). Conclusion: These findings strengthen the belief that SP-6 acupressure can be used to relieve anxiety during labor with no side effects to either mother or baby.

The discrete wavelet transform (DWT) has good multi-resolution decomposition characteristic and its low frequency component contains the basic information of an image. Based on this, a fragile watermarking using the local binary pattern (LBP) and DWT is proposed for image authentication. In this method, the LBP pattern of low frequency wavelet coefficients is adopted as a feature watermark, and it is inserted into the least significant bit (LSB) of the maximum pixel value in each block of host image. To guarantee the safety of the proposed algorithm, the logistic map is applied to encrypt the watermark. In addition, the locations of the maximum pixel values are stored in advance, which will be used to extract watermark on the receiving side. Due to the use of DWT, the watermarked image generated by the proposed scheme has high visual quality. Compared with other state-of-the-art watermarking methods, experimental results manifest that the proposed algorithm not only has lower watermark payloads, but also achieves good performance in tamper identification and localization for various attacks.

Purpose: Lateral osteotomy is an essential step in the correction of nasal bony asymmetry. Direct visualization allows accurate repositioning of the nasal bones compared to blind techniques, which require precision and manual dexterity. We propose direct visualization procedures in open corrective rhinoplasty. Methods: The technique was used on 16 patients. All patients underwent open rhinoplasty with a columellar incision. The marginal incisions were extended on either side to allow access to the piriform aperture. A double hook was used to caudally retract the lower lateral cartilages and the fibrous connections between the upper and lower lateral cartilages were released until the piriform aperture was visualized. Through the incision, lateral osteotomy was performed using a reciprocating saw at that time with direct visualization. Additional procedures including augmentation rhinoplasty, hump resection, septoplasty and tip plasty were performed simultaneously. Results: This method provided excellent exposure to the lateral nasal bones and allowed the lateral osteotomy to be carried out precisely using the reciprocating saw. Conclusion: This extended open rhinoplasty method is suitable for most individuals, allowing a wide surgical field.

Background: Previous researchers have investigated the mechanical and neurophysiological effects of manual mobilization, however little research has been done on muscle tone and muscle stiffness. Objective: To compare the effects of posterior-anterior (PA) mobilization with weight bearing on sling and conventional PA mobilization on the bed. Design: Randomized controlled trial (single blind) Methods: The subjects were 16 male university students and randomized to sling mobilization group (SMG, n=8) or conventional mobilization group (CMG, n=8). SMG received PA mobilization using a sling and CMG received traditional mobilization on the bed during lumbar mobilization. Results: Both left and right muscle tones of SMG increased, but left muscle tone of SMG were increased and right muscle tone was decreased after intervention. In addition, both left and right muscle stiffness of SMG were also increased, however left muscle stiffness of SMG was increased and right muscle stiffness was decreased. The muscle tone and muscle stiffness of SMG were higher than those of DMG, especially the right side was statistically significantly higher. Extension of SMG, extension and flexion of CMG were increased statistically significantly except for Flexion of SMG (p<.05). There were no significant differences between the groups in Extension and Flexion. Conclusions: This study suggests that lumbar spine PA mobilization using sling is beneficial in improving muscle tone, muscle stiffness, and trunk movement.

Recently, it has been argued that it is necessary to attract foreign patients outside domestic insurers and to allow foreign doctors to treat in domestic hospitals in order to develop the insurance industry and revitalize the medical industry. Currently, large medical institutions in Korea are attracting foreign patients in connection with foreign insurance companies. It is desirable to increase the number of overseas patients who want excellent medical services in Korea, and to provide opportunities for domestic insurance companies to attract overseas patients by expanding job creation through a revitalization of the medical industry. Therefore, this study suggests the development direction for insurers who aim to attract foreign patients through the side effects of attracting foreign patients in accordance with the Financial Services Commission's plan to strengthen the competitiveness of the financial industry. In addition, this study intends to contribute to the strengthening of the competitiveness of attracting foreign patients, through domestic insurance business, to the insurance direct payment market for overseas patients using domestic medical institutions that are concentrated in foreign insurance companies and in the blind spot of domestic law application.
