Postinsertion problems tend to be minimized when a sequential insertion procedure is followed. However, problems may occur as the result of one or any combination of comfort, function, esthetics, and phonetic difficulties. Following the insertion of a partial denture, an appointment for review in approximately 7 days should be made for the patient. At the review visit, the patient should be questioned concerning any problems that have been experienced when wearing the denture. A thorough examination should then be carried out of the oral tissues and the denture, in the course of which signs of tissue damage may be observed. A diagnosis is then made of the cause of all the problems revealed in the history and examination procedures. Appropriate treatment should then be applied to resolve these problems.

The Theory of Meridian can be classified into early form of pre- and present form of after-. The representative early form of meridian is Eleven Meridians in Mawangdui scrolls(馬王堆帛書) which use Six Qi Diagnosis(六氣辨證). because it did not adopt Visceral Pattern Identification(臟腑辨證). The present form of meridian is Twelve Meridians of . It has developed to investigate relations between Visceral and disease with Five Phase Theory. Analyzing the name of the Six Meridians in the Shanghanlun(傷寒論)On Cold Damage, there are no hands, feet and visceral signs. and it is almost identical to Eleven Meridians in Mawangdui scrolls. According to , Eleven Meridians use only Six Foot Meridians(足六經) to classify diseases. This fact was applied identically to the Six Meridians in the Shanghanlun. Therefore many doctors, especially Hanzhihe(韓祗和) and Zhangzhicong(張志聰) mentioned that "I have never seen a book on Shanghanlun discuss about Hand Meridians(手經)."

In this paper, a low cost, low power but multifunctional wireless sensor node is presented for the impedance-based SHM using piezoelectric sensors. Firstly, a miniaturized impedance measuring chip device is utilized for low cost and low power structural excitation/sensing. Then, structural damage detection/sensor self-diagnosis algorithms are embedded on the on-board microcontroller. This sensor node uses the power harvested from the solar energy to measure and analyze the impedance data. Simultaneously it monitors temperature on the structure near the piezoelectric sensor and battery power consumption. The wireless sensor node is based on the TinyOS platform for operation, and users can take MATLAB$^{(R)}$ interface for the control of the sensor node through serial communication. In order to validate the performance of this multifunctional wireless impedance sensor node, a series of experimental studies have been carried out for detecting loose bolts and crack damages on lab-scale steel structural members as well as on real steel bridge and building structures. It has been found that the proposed sensor nodes can be effectively used for local wireless health monitoring of structural components and for constructing a low-cost and multifunctional SHM system as "place and forget" wireless sensors.

Percutaneous osteoplasty (POP) is defined as the injection of bone cement into various painful bony lesions, refractory to conventional therapy, as an extended technique of percutaneous vertebroplasty (PVP). POP can be applied to benign osteochondral lesions and malignant metastatic lesions throughout the whole skeleton, whereas PVP is restricted to the vertebral body. Common spinal metastases occur in the thoracic (70%), lumbosacral (20%), and cervical (10%) vertebrae, in order of frequency. Extraspinal metastases into the ribs, scapulae, sternum, and humeral head commonly originate from lung and breast cancers; extraspinal metastases into the pelvis and femoral head come from prostate, urinary bladder, colon, and uterine cervical cancers. Pain is aggravated in the dependent (or weight bearing) position, or during movement (or respiration). The tenderness and imaging diagnosis should match. The supposed mechanism of pain relief in POP is the augmentation of damaged bones, thermal and chemical ablation of the nociceptive nerves, and local inhibition of tumor invasion. Adjacent (facet) joint injections may be needed prior to POP (PVP). The length and thickness of the applied needle should be chosen according to the targeted bone. Bone cement is also selected by its osteoconduction, osteoinduction, and osteogenesis. Needle route should be chosen as a shortcut to reach the target bony lesions, without damage to the nerves and vessels. POP is a promising minimally invasive procedure for immediate pain relief. This review provides a technical survey for POPs in painful bony lesions.

An efficient cost management is important for the domestic social overhead capital(SOC) based on a long lifecycle after 30 years since completion. Maintenance in South Korea have had the restrictions of consistency and suitability of decision-making by the establishment of a budget plan based on the company estimate and repair and reinforcement methods determined by the inspection and diagnosis engineers' subjective determination for each facility. To resolve this issue, the Korea Institute of Civil Engineering and Building Technology is currently in development of a methodology to propose an optimum maintenance method according to the damage of components by artificial intelligence. This study has deduced the primary factors by analyzing information generated during bridge maintenance and management as a prior step for the development of technologies, and conducted a preliminary analysis to select the optimum artificial intelligence technology.

Granulomatosis with polyangiitis (GPA) and Immunoglobulin (Ig) $G_4$-related disease ($IgG_4$-RD) are rare diseases and early diagnosis and proper management are imperative to prevent multi-organ damage. The authors present a case of a 60 years old woman who had facial paralysis and hearing loss. Lt intact canal wall tympanomastoidectomy, Lt facial nerve decompression and ossiculoplasty with partial ossicular replacement prosthesis (PORP) was done. During operation, middle ear tissue was biopsied and GPA with $IgG_4$-RD was diagnosed. After methyl prednisolone (MPD) pulse therapy and azathioprine therapy, the severity of paralysis was improved. We present this case because common otologic symptoms like facial palsy and hearing loss could be initial symptoms of rare systemic disease.

Incidence of basal and squamous cell carcinoma is increasing among Korean. With increasing this incidence we need to attend the management and prevention of these cutaneous malignancies. Basal cell carcinoma (BCC) is the most common skin malignancy. Sun exposure is the most important environmental cause of BCC. Daily sun protection especially avoiding sun exposure between 10 a.m. and 4 p.m. provides most effective prevention against chronic ultraviolet-induced skin damage. Hedgehog pathway inhibitors are used locally advanced and metastatic BCC lesions in Korea. Until recently, there are no reports whether it developed resistance of Hedgehog pathway inhibitors with advanced BCC in Korean patients. Among malignant skin tumors, 19.1% were squamous cell carcinoma (SCC). The incidence of SCC was rapidly increased over the past years. However, the incidence rate of SCC in Japan has not been changed from the period 1976-1980 to 1986-1990. Sentinel lymph node biopsy for SCC did not provide diagnostic value. Bowen's disease and Erythroplasia of Queyrat are considered as carcinoma in situ of the skin. Erythroplasia of Queyrat have worse prognosis with a higher rate of malignant degeneration. Dermoscopy may helpful tool in assisting the noninvasive diagnosis of carcinoma in situ of the skin.

Purpose: The purpose of the study was to investigate traumatic urethral injury in a 63-year-old patient with hematuria. Methods: A hematuria patient was transferred by paramedics. At the time of the visit, the patient's blood pressure (151/91mmHg), pulse rate (86/min), body temperature (37.1℃), and other vital signs were stable. Their KTAS (Korean Triage and Acuity Scale) was Level 4. The patient had no damage to the injured area, but a large contrast defect was observed between the prostate urethra and the bladder in urethral angiography performed due to persistent hematuria and pain in the injured area. Results: Following radiological evaluation of a suspected liposarcoma or neuroma mass of the prostate urethra, the mass was removed through urethral tumor resection. The result of histologic evaluation provided a diagnosis of highly differentiated invasive urethral cell carcinoma that had invaded the muscle layer. The patient was given additional treatment for urethral cancer but was rejected and is currently being followed. Conclusion: The prognosis for urinary tract cancer has distinct differences for patients with lymph node metastasis and tumor characteristics. The presence or absence of urethral cancer should be confirmed through angiography, CT, MRI, and cystoscopy.

Evaluating the patient's voice before thyroidectomy is useful for the purpose of identifying patients with vocal cord paralysis without symptoms, identifying other patient's voice abnormalities, and whether it is related to voice disorders that may occur after surgery. Also voice evaluation after thyroid surgery is helpful in diagnosis, treatment, and rehabilitation and follow-up of voice disorders that occur without clear nerve damage after thyroidectomy. And it is helpful for rapid recovery through active early rehabilitation treatment for patients who complain of speech impairment without paralysis. In particular, neck exercise can improve the adhesion of the surgical site and increase the range of motion of the neck as well as improve subjective neck discomfort. In addition, hearing, voice and breathing functions should be improved, and voice hygiene education and counseling should be provided. Vocal cord injection is the first treatment option for unilateral vocal cord palsy. By establishing a protocol for voice disorders before and after thyroid surgery and providing appropriate treatment, the quality of life of patients can be improved.
