The appearance of a tumor in the chest wall is rare compared to that in any other part of the body. It can be classified into benign and malignant types and can be located in the rib, clavicle, sternum, cartilage and soft tissues. Tumors that are metastatic are commonly located in the lung, breast, bone and pleura. But, the soft tissue mass of anterior chest wall is rarely metastasized from a distant organ that is not confined to the thoracic cavity. This and thus has rarely been described. A 68-year-old man was admitted to our hospital with a chief complaint of resting dyspnea. A huge non-tender mass of about $10{\times}15$ cm in size was visible on his left lower anterior chest wall. We pathologically confirmed that the mass was a metastatic renal cell carcinoma of clear cell type by incision biopsy. Through an incision biopsy, the mass was pathologically confirmed as a metastatic renal cell carcinoma of the clear cell type.

A benign metastasizing pulmonary leiomyoma (BMPL) is a rare disease that usually occurs in women with a prior or coincident history of uterine leiomyoma. Although leiomyoma is histologically benign, it has the potential to metastasize to a distant site such as the lung. A 35 year old woman who had undergone a hysterectomy due to uterine leiomyoma 5 years prior was admitted for an investigation of multiple pulmonary nodules on a routine chest roentgenogram. An open lung biopsy was taken to make a pathological diagnosis. The microscopic finding of the nodules was leiomyoma and was similar to those of the uterine leiomyoma that had been resected 5 years ago. The woman underwent wedge resections of all pulmonary nodules. This is the first case of BMPL in Korea, which was treated with wedge resections of all multiple pulmonary nodules.

A method that effectively precipitates capsular polysaccharide of Haemophilus influenzae type b (polyribosylribitol phosphate, PRP) conjugated to tetanus toxoid (TT), PRP TT in a liquid vaccine has been developed to measure free PRP present in TT-conjugate vaccine. The method involves adding anti-TT antibody and ammonium sulfate to precipitate PRP-TT conjugate and measuring free PRP in tile supernatant. This new method provides a complete precipitation of the total PRP-TT, and provides an accurate and reproducible measurements of free PRP. The accuracy of the assay was confirmed by spiking known amounts of unconjugated PRP to PRP-TT conjugate, and the new method was found to have no effect on free PRP while precipitating PRP-TT. The published acid precipitation method did not produce reproducible results due to incomplete precipitation of PRP-TT, especially when the vaccine is formulated in a salt-buffered solution.

A new method for measuring optical phase changes of reflection beam from optical mirror is proposed. The optical phase change is liable to change with varying atmosphere conditions. This optical phase changes are measured against air pressure, temperature, humidity and CO$\_$2/ concentration variations. It is clarified that the optical phase changes are most effected by humidity change.

We propose a multifunctional power line compensator (PLC) which can individually compensate multiple impediments at the same time. The PLC has the flexibility to share power to each compensation according to commands, this improving the working rate. We constructed a 100kVA PLC model including a controller with digital signal processor (DSP) to realize a multifunctional compensation were obtained.

Lung cancer, breast cancer and lymphoma are the common oncologic causes of malignant pleural effusion, comprising more than the half of the causes. However, an endocrinologic carcinoma associated malignant effusion is very rare. Recently, we encountered a case of papillary thyroid carcinoma causing malignant effusion. An 83-year-old female patient presented with dyspnea due to massive pleural effusion in her left side. The pleural biopsy, pleural fluid cytology and breast needle aspiration biopsy results were consistent with a metastatic papillary thyroid carcinoma. Thyroid ultrasonography showed two thyroid masses, but the patient refused a thyroid biopsy. This case highlights the need for considering the possibility of papillary thyroid carcinoma when the cause of malignant pleural effusion cannot be found because one of the rare clinical manifestations of a papillary thyroid carcinoma can be dyspnea due to malignant effusion.
