Pleomorphic adenoma is one of the most common benign neoplasm of salivary glands and resection with enough normal tissue margin is important treatment for preventing the local recurrence. For palate tumor involving both soft palate and hard palate, palatal fistula is easier to occur as post-operative complication after resection of the tumor. The palatine aponeurosis is important anatomical barrier between soft palate and nasal cavity, and we found that by using palatine aponeurosis as surgical plane, we can do R0 resection of the tumor with preventing the palatal fistula complication. Also, we used inguinal full thickness skin graft to protect the exposed palatine aponeurosis in some cases. We analyzed 4 cases of palate pleomorphic adenoma resection using palatine aponeu- rosis as surgical plane and those operations were done by single surgeon. All of 4 patients had no palatal fistula and also had no recurrence of the tumor during the post-operative course.

Nasal cavity and paranasal sinus cancers comprise about 1% of all malignancies, and 5% ofhead and neck malignancy. Squamous cell carcinoma comprises more than half of nasal cavi-ty cancers. Treatment is determined by considering tumor size, location, staging, age, generalcondition, purpose of treatment, etc. Conventional therapy includes surgery, radiotherapy, andchemotherapy; however, for the locally advanced, recurrent, or metastatic cancer after con-ventional therapy, immunotherapy or targeted therapy are taken into consideration. Targettherapy attacks specific cancer cells directly, such as cancer cells with certain gene mutation,whereas immunotherapy attacks cancer cells indirectly, stimulating our own immune system,such as T-cell activity. Histologically poorly differentiated carcinomas are treated with sur-gery, radiotherapy, and sometimes chemotherapy, but 5-year survival rate is low due to fre-quent recurrence. Here, we present a case of successful targeted therapy applied to recurrentnasal cavity cancer after serial application of conventional therapies.

The wireless communication system applied in the building automatic control system has been studied by reflecting the recent evolution of the automatic building control system from the wired system to the wireless system. The wired system applied in the existing building automatic control system is compared by the latest wireless system, and quantitatively analyzed the advantages gained by applying the wireless system with examples of actual field application. This wireless communication system will be able to contribute to the development of building automatic control systems that apply wireless systems in the future by analyzing the performance and stability of the wireless system and deriving the necessary items in the field.
