Background: Metastatic cancer with invasion of skin, soft tissue and skeletal muscle is not common. Examples presenting as soft tissue masses could sometimes lead to misdiagnosis with delayed or inappropriate management. The purpose of current study was to investigate clinical characteristics in the involvement of metastatic cancer. Materials and Methods: A total of 1,097 patients complaining of skin or soft tissue masses and/or lesions were retrospectively reviewed from January 2012 to June 2013. Tumors involving skin, soft tissue and skeletal muscle of head and neck, chest wall, abdominal wall, pelvic region, back, upper and lower extremities were included in the study. Results: Fifty-seven (5.2%) patients were recognized as having malignancies on histopathological examination. The most common involvement of malignancy was basal cell carcinoma, followed by cutaneous squamous cell carcinoma, sarcoma and melanoma. The most common anatomical location in skin and soft tissue malignancies was head and neck (52.6% of the malignancies). Four (0.36%) of the malignant group were identified as metastatic cancer with the primary cancer source from lung, liver and tonsil and the most common site was upper extremities. One of them unexpectedly expired during the operation of metastatic tumor excision at the scalp. Conclusions: Discrimination between benign and malignant soft tissue tumors is crucial. Performance of imaging study could assist in the differential diagnosis and the pre-operative risk evaluation of metastatic tumors involving skin, soft tissue and skeletal muscle.

Electroencephalography (EEG), a representative method of identifying temporal and spatial changes in brain activity, is a voluntary electrical activity measurable in the human scalp. Various interface technologies have been provided to control EEG activity, and it is possible to operate a machine such as a wheelchair or a robot through brainwaves. The characteristics of EEG data are collected in various types of channels in real time, and a server system for analyzing them is required to have an independent and lightweight system for the platform. In these days, the Spring platform is used as a large business server as an independent, lightweight server system. In this paper, we propose an EEG analysis system using the Spring server system. Using the proposed system, the reliability of EEG control can be enhanced, and analysis and control interface expansion can be provided in various aspects such as game and medical areas.

It was to establish the usage possibility as cosmetic material by testing stimulation of Leuconostoc mesenteroides which were cultured from human scalp's dead skin cell by patching it to the skin in the form of solubilized essence. Cultured L. mesenteroides diluted to 1% concentration and essence which contains it were patched to 31 and 32 participants' back each for 24 hours and established the stimulus figures by the specialists in 30 minutes, 24 hours, and 48 hours after they were taken off. They are both revealed as non-stimuli due to the result of 0.011 and 0 points each and therefore they are safe when used as skin products. Considering the results of this test and the other previous studies which reported the L. mesenteroides as anti-allergic, antioxidant, and anti-inflammatory, L. mesenteroides is usable for cosmetics and worth further research.

With the launch of Artificial Intelligence(AI)-based intelligent products on the market, innovative changes are taking place not only in business but also in consumers' daily lives. Intelligent products have the potential to realize technology differentiation and increase market competitiveness through advanced functions of artificial intelligence. However, there is no new product development methodology that can sufficiently reflect the characteristics of artificial intelligence for the purpose of developing intelligent products with high market acceptance. This study proposes a KANO-QFD integrated model as a methodology for intelligent product development. As a specific example of the empirical analysis, the types of consumer requirements for hair loss prediction and treatment device were classified, and the relative importance and priority of engineering characteristics were derived to suggest the direction of intelligent medical product development. As a result of a survey of 130 consumers, accurate prediction of future hair loss progress, future hair loss and improved future after treatment realized and viewed on a smartphone, sophisticated design, and treatment using laser and LED combined light energy were realized as attractive quality factors among the KANO categories. As a result of the analysis based on House of Quality of QFD, learning data for hair loss diagnosis and prediction, micro camera resolution for scalp scan, hair loss type classification model, customized personal account management, and hair loss progress diagnosis model were derived. This study is significant in that it presented directions for the development of artificial intelligence-based intelligent medical product that were not previously preceded.

This study examined the neurophysiological mechanisms of exercise deprivation by investigating differences in emotion changes and EEG prefrontal asymmetry in relation with exercise. Twenty male undergraduate university students in the 23-27 age range, amateur marathon runners, were selected as the participants (n=20) and divided into one of two experimental conditions at random: (1) exercise deprivation group (n=10), and (2) non-exercise deprivation group (n=10). PANAS-X measurement and EEG measurement from F3 and F4 scalp sites were performed at pre-test, 3 days after exercise deprivation, and 5 days after exercise deprivation. Results revealed that participants of EDG significantly decreased a positive effect after exercise deprivation on EEG and self-reported measures, and showed an increased negative effect after exercise deprivation on self-reported measures. In contrast, participants of NEDG significantly increased positive feelings after exercise and showed a decreased negative effect after exercise on EEG and self-reported measures. Our results showed that exercise deprivation increasing negative emotion after exercise deprivation. The findings of this study suggest that EEG frontal brain asymmetry can be used as diagnosing method for exercise deprivation.

Microvascular surgery has been widely used clinically for over 30 years. Although many types of free skin and myocutaneous flap are being used at present, surgeons are still looking for new flaps to suit the specific requirements of different recipient sites, to reduce the deformity at the donor site, to ease the management of the flap and to increase the success rate of those operations. The lateral thigh free flap was designed and reported simultaneously with the medial thigh free flap by Baek in 1983. The flap, based on the third perforator of the profunda femoris artery. is designed on the posterolateral aspect of the distal thigh. Clinically, the vascular variations and the locations of perforators of this system can be determined preoperatively with simple angiograms and Dopper audiometry. The lateral thigh free flap is suitable for reconstruction of defects in an oral floor with tongue and esophageal deficits, scalp defects with dural defects, and large full thickness defects of the lip. The advantages of this flap are safe elevation, a long vascular pedicles with a large lumen, skin that is generally thin, and good pliability. Furthermore, the skin territory is very wide and long. The donor site is hidden and therefore more acceptable to the patient. The disadvantage of this flap is that the anatomy of the pedicle vessels has irregular derivation from the main vessel. We had reconstructed lateral thigh free flap to the nine patients from January, 1997 to July, 1998 and got satisfactory results. In this paper we illustrate the arterial anatomy of the thigh and usefulness of this flap for the reconstruction of the head and neck.
