To deal with tumor motion from respiration is one of the important issues for the advanced treatment techniques, such as the intensity modulated radiation therapy (IMRT), the image guided radiation therapy (IGRT), the three dimensional conformal therapy (3D-CRT) and the Cyber Knife. Studies including the active breath control (ABC) and the gated radiation therapy have been reported. Authors have developed the device for reducing the respiration effects and the diaphragm motions with this device were observed to determined the effectiveness of the device. The device consists of four belts to immobilize diaphragm motion and the vacuum cushion. Diaphragm motions without and with device were monitored fluoroscopically. Diaphragm motion ranges were found to be 1.14 ～ 3.14 cm (average 2.14 cm) without the device and 0.72～1.95 cm (average 1.16 cm) with the device. The motion ranges were decreased 20 ～ 68.4% (average 44.9%.) However, the respiration cycle was increased from 4.4 seconds to 3.7 seconds. The CTV-PTV margin could be decreased significantly with the device developed in this study, which may be applied to the treatments of the tumor sited diaphragm region.

Background: Endovenous laser treatment has recently been introduced as a less invasive technique, with many good results reported, A 980-nm diode laser was used on the great saphenous vein (GSV) occlusions in patients with varicose veins, due to GSV reflux, and the therapeutic effects analyzed. Material and Method: Between September 2003 and February 2006, 238 patients (332 cases) with GSV reflux underwent endovenous laser treatment with a 980-nm diode laser. Operative procedures were simultaneous endovenous laser treatment and ambulatory phlebectomy. The preoperative clinical findings, postoperative complications and postoperative duplex US follow up results at 1 and 3 months were reviewed. Result: Postoperative complications were ecchymosis in almost cases, paresthesia 68 cases (20.5%) and skin burn in 3 cases (0.9%). Follow up duplex US revealed 26 and 10 cases at 1 and 3 months of GSV reflux or partial recanalization, with therapeutic success rates of 91.3 and 87.9%, respectively. Conclusion: The treatment of GSV occlusion with an endovenous laser is less invasive than traditional GSV stripping, but relatively high recanalization was experienced, possibly due to inadequate laser power, laser fiber pullback speed or an extremely dilated GSV. However, continuous attempts will be required to reduce the recanalization after the procedure, with accurate follow up using duplex US.

This case study aimed to investigate changes in adolescents' awareness of the motivation behind their excessive internet gaming after group music psychotherapy. Five middle school students participated in six 60-minute group sessions over 4 weeks. The group music psychotherapy program was developed to help participants understand their implicit reasons for excessive internet gaming. Verbal responses were obtained from pre-program and post-program interviews and original lyrics created by participants during program were collected for analysis. Obtained data were analyzed in terms of emotional and cognitive aspects in relation to the participants' awareness of the motivation behind their excessive gaming. The results showed that song writing as creative musical process allowed participants to be aware of positive and negative influence of gaming on themselves and express their motivation to change their perception on gaming behavior. Also, the participants reported that the use of musical product for their daily lives could be an effective coping strategy to manage their gaming behaviors and an alternative for gaming. The findings from this study support that group music psychotherapy can be an effective approach to promote awareness of adolescents' motives for excessive internet gaming and to help adolescents better manage their gaming behaviors.

Traditional method of pulpectomy for a necrotic primary anterior tooth was done on lingual side. But it could not recover the discoloration of crown effectively. For the purpose of treating the discoloration of crown after lingual pulpectomy, additional methods of crown restoration were needed like : celluloid crown, open-faced crown, rasin-faced crown. Neverthless, these kinds of complete coverage methods had some disadvantages such as possibility of tooth fracture by increased tooth preparation. In order to overcome the shortcomings of lingual pulpectomy, labial treatment could be considered as an alternative. It is a method that treats necrotic pulp through the labial access opening. After finishing the pulp treatment, discolored labial tooth structure was removed extending from access opening. Discoloration of deep area could be masked effectively using opaque sealant. Cavity on labial side was restored with composite resin. This labial approach method has several advantages. First, it gives a direct vision for effective pulp treatment which is also very useful for children with poor behavior. Second, most of lingual tooth structure could be saved and occlusal contact of lingual surface remains undisrupted. Only nonfunctional discolored labial surface may removed. Third, complete removal of discolored part of a labial tooth and immediate resin restoration could be done effectively after pulp treatment. Moreover, it also could be used for pulp treatment having serious dental caries on labial surface with sound lingual tooth structure. This report presents cases with discolored upper anteior primary tooth, approaching labial side with successful restoration.

Neurofibromatosis is a rare systemic disease, and genitourinary tract involvement is especially uncommon. Bladder is the most frequently involved organ in the genitourinary tract. Bladder neurofibromatosis may present as a diffuse infiltrative process or an isolated neurofibroma. The symptoms vary, ranging from urinary incontinence to retention. Treatment is usually conservative. The patient should be worked up to rule out other manifestation of tumor enlargement and followed to evaluate the development of new lesion. We report a case of the development of invasion of bladder in a patient with neurofibromatosis.

The purpose of this qualitative study was to describe the experience of mothers who have had children with cancer. Participants were seven mothers who had children diagnosed with cancer between 3 to 36 months. Data were gathered through in-depth interviews and analyzed by Colaizzi's phenomenological methodology. Overall, 216 significant statements, 62 formulated statements, 16 themes and five theme clusters were identified. The five theme clusters were 'heartbreaking sadness', 'arduous journey of battling', 'protect my child', 'feeling varying between gratitude and disappointment', and 'suffering and wishing to be with family'. Mothers who have had children with pediatric cancer receiving chemotherapy have experienced strong emotional fluctuations as well as hope as they cope with their ill child. However, they try to become strong women and embrace their family to cope with their situation. The results of this study will support for health professionals to understand mothers who have had children with cancer and to consider the supportive nursing care in considering mothers' emotional fluctuation.

Descending necrotizing mediastinitis is a life-threatening infection originating in the head or the neck and descends into the mediastinum. Even in the era of antibiotics, mortality rate has been reported to be 25 ∼ 40%. Prompt diagnosis and treatment is mandatory for delayed diagnosis and inappropriate drainage of the mediastinum are the main causes of high mortality Surgical management ranges from cervical drainage to routin thoracotomy:however, the optimal management still needs to be defined particularly in respect to effective mediastinal drainage. Although posterolateral thoracotomy incision has been considered as a standard approach, potential disadvantages including postoperative pain, risk of wound complication and delayed recovery remain to be concerned. Thoracoscopic approach is an attractive treatment modality as it can provide an excellent exposure with minimal incision and can complete drainage from the mediastinum and the neck in one-staged manner We describe here two cases of descending necrotizing mediastinitis successfully managed by thoracoscopic drainage.

Recently, as elderly people suffering from chronic diseases have increased and disasters such as traffic accidents have increased, urgent rescue workers and doctors need to respond effectively to such emergencies. For elderly people, the difficulty in communicating their condition especially the health condition during disaster is one of the problems in which delay on immediate handling by rescue team can cause death. Providing a solution for this problem is one of the main issues in our research. In this paper, we use the QR code to communicate the minimum personal information and medical history needed for emergency medical treatment to emergency medical personnel, and to transmit the medical history and treatment data to the doctors of the hospital through QR code and fingerprint recognition, respectively. Especially, by using both QR code of smart phone and fingerprint of individual, we can protects personal information and strengthens privacy and security of medical information by allowing only authorized physicians to check medical records of the old patient.
