This paper describes the design and fabrication process of super water-saving toilet bowl system by the theory of inventive problem solving (TRIZ). The physical contradiction in TRIZ is defined to obtain the conceptual design for saving water in toilet bowl system with preventing the bad smell from septic tank. The super water-saving toilet bowl system is obtained by using the separation principle in time for resolving the physical contradiction. The consumption of water in the prototype system fabricated, is estimated about $3{\ell}$ comparing with $13{\ell}$ of that in conventional toilet bowl system. The noise from water in the prototype toilet bowl system is decreased by 1/3 of that in conventional toilet bowl system.

Reports of osteomyelitis in the proximal humerus with pyogenic glenohumeral arthritis of adjacent joints mostly involve pediatric patients. Nowadays, osteomyelitis that is secondary to adjacent pyogenic glenohumeral arthritis is extremely rare, even more so in adults than in pediatrics. We report a rare case of the pyogenic glenohumeral arthritis followed by osteomyelitis of the proximal humerus in an elderly patient. Initially, we diagnosed a case of pyogenic glenohumeral arthritis only, which, despite arthroscopic synovectomy, did not resolve and severe pain continued. Subsequent radiological imaging, performed after our suspicion of a secondary involvement, allowed us to diagnose osteomyelitis combined with the pyogenic glenohumeral arthritis, which we had overlooked because of the extreme rarity of the condition in adults since the antibiotic era began.

A clinical evaluation was performed on 76 cases of chest injury experienced at department of Chest Surgery, Capital Armed Forces General Hospital during the past 3 years period from January 1981 to August 1983. 1.The most common cause of the chest trauma was gun shot by which 26 cases were injured among 44 cases [57.9%] of penetrating injury. Remaining 32 cases [42.1%] were injured by non-penetrating blunt trauma. 2.Hemopneumothorax was observed in 60 cases [78.9%], those were caused by both penetrating [65%] and non-penetrating [35%] injuries. 3.Rib fracture was found in 58.7% of total cases and with rib fracture, clavicle fracture was combined at 19.6% and sternal fracture, at 8.7%. 4.Most common symptoms were chest pain and dyspnea, and most common signs were breath sound diminution and subcutaneous emphysema. 5.Common site of rib fracture was from 4th rib to 8th rib [69.4%]. 6.In 58 cases [76.3%], patients were treated with operation including open thoracotomy [25 cases]. 7.Overall mortality was 5.3%[4 cases] and causes of death were septic shock and respiratory failure.

Between November 1990 and December 1993, 9 patients underwent surgical intervention for acute active endocarditis at Gyeongsang National University Hospital. All the patients were operated on within the first six weeks after onset of symptoms for various reasons. Surgical indications for early surgery were heart failure, systemic septic emboli, new murmur and growing vegetation. Most common infecting organism was Staphylococcus[55 %], and the others were Streptococcus, anaerobes, Candida and unknown in 1 case. The infection was in the mitral valve in 5 patients, the aortic valve in 2, the aortic and mitral in 1, and the aortic and pulmonary in 1. There was one operative death[11 %] and no late death. Preoperative Functional Class were II in 4 patients, III in 5 and after surgery all the patients improved to Class I. We conclude that early surgical intervention in acute active endocarditis is effective in most instances.

in general rapid and complete resolution of pulmonary emboli, even massive, is the natural history. However, rarely, the emboli do not resolve but rather became fibrotic organization and densely adherent to the arterial wall, therefore, may lead to significant clinical disability. In patients with chronic pulmonary embolism, medical management usually has little effect and only surgical treatment can offer improvement. The case was 30-year-old man who had admission to the Hanyang University Hospital due to fall-down from 11th floor 407 days before operation and then transferred to our department for surgical management under the diagnosis of chronic pulmonary embolism, Pulmonary angiogram demonstrated multifocal thromboembolism with infarction and lung scans showed no improvement in spite of anticoagulant and thrombolytic therapy. At median sternotomy for pulmonary artery thromboembolectomy, the well organized and multiple septic emboli could be removed by gallstone forceps. But reoperation of left upper lobectomy was performed because of the repeated hemoptysis and suspicious pulmonary arterio-bronchial fistula 19 days postoperatively. Despite of ventilatory support and drug treatment, the patient died due to right heart failure associated with cor pulmonale 27 days after first operation. Discussion of the operative and perioperative problems are offered.

Bacteremia is the transient presence of bacteria (or other microorganisms) in the blood. Bacteremia may result no symptom to the healthy persons, but it may result symptoms such as pylexia, headache and even septic shock to the patient in immunosuppression. In this case, a 75 years old male patient had a dental caries and cerebrovascular accident ago, therefore was in a bad condition and often caught cough. Suddenly be bad a headache with a high fever caused by Streptococcus Mutans Bateremia. After defervescence, a slight fever and a headache remained. It may the symptoms of Yolgwol headache(熱厥頭痛) , so Cbeougsaugsabwa-taug(淸上瀉火湯), the symptoms such as a slight fever and a headache are on the mend.

Lemierre syndrome is caused by acute oropharyngeal infections with secondary septic thrombophlebitis of the internal jugular vein and is characterized by frequent metastatic infections. A 56-year-old man presented with severe reddish inflammatory swelling of the right cervical soft tissue. Thrombophlebitis in the right internal jugular vein and multiple pulmonary embolisms were identified on neck and chest computed tomography (CT). He was treated with antibiotics and heparin for 4 weeks and then discharged without other complications.

Recently, according to the increase of population and rapid growth of industry, the amount of effluent pollutant has been rising in natural water. In these pollutant, nutrients such as nitrogen and phosphor are told that these evolve the odor, color and eutrophication in rural housing sewage and lake regulary. Many researches have been carried out to remove these nutrients from effluents and will have to be studied more deeply. Especially, because of the sewage of rural housing and livestock, environmental pollution raises serious problem in a rural community. This method is developed to solve the problem environmentally friendly. Using the natural energy(wasteheat, earthheat, solar engery) and the growth properties of aquatic plants are most efficient method to absorb the nutrients and denitrification and phosphor uptake.

Nuclear factor ${\kappa}$B (NF-${\kappa}$B) represents a family of eukaryotic transcription factors participating in the regulation of various cellular genes. Since aberrant regulation of NF-${\kappa}$B has been implicated in the pathogenesis of various diseases including inflammation. asthma. atherosclerosis. AIDS. septic shock. arthritis, and cancer. this transcription factor has been shown to be an interesting target of new drug discovery. (omitted)

This paper presents the result of groundwater analysis in Changwon area and the characteristics of the groundwater properties. Changwon city conducted groundwater analysis at 551 sites in 1996 and 1997. The water quality is suitable as groundwater use at 466 sites (84.6 %) and exceeds maximum contaminant levels (MCLs) at 85 sites (15.4 %). Major contaminants are total bacteria, coliform and nitrate-N. DNAPLs, e.g. TCE and PCE are detected in the areas of industrial complex and residence. The detection of TCE and PCE is due to organic solvents from manufacturing companies. They are also derived from laundries, Photographer's studios, septic tanks, etc. In addition, fifty groundwater samples were analyzed. Iron, manganese, zinc, copper, lead, aluminum and fluorine are detected in nearly all the groundwater samples. The groundwaters shown on the Piper diagram mostly belong to Ca-HCO$_3$ type.
