Wi-Hang Literature was first introduced in the latter part of the 17th century by Wi-Hang poets. It enjoyed its peak time in the 18th century and decayed in the 19th century. One of the great changes in the latter part society of the Yi Dynasty was that art started to have new developments. Along with music and paintings we could see such kind of phenomena in literature Wi-Hang-In, while accepting the contents and forms of Chinese poetry and prose, started to show some characteristics in their own. In this study the author has attempted to make a research into some characteristics in terms of contents and forms of Wi-Hand Literary works which are differnent from those of Yang-Ban Sa-Dae-Bu. Firstly, in contents, they criticized the reality of their days, brought a charge against the miserable situations of farmers, wrote a lot of poems in retrospection and sentimentalism by the name of Young-Sa-Si. They also produced many works reflecting diversified feelings of people's daily life realistically, turned daily words into poetic diction, used satire and humour frequently, trying to express Cheon-Gi and nature faithfully.

Background: Although dental implantation has become widespread and acceptable treatment for dental prosthodontics, maxillary posterior jaw region is often complicated by the pneumatization of the maxillary sinus and physiological resorption of the alveolar bone. When this occurs, the residual bone between the floor of the sinus and the crestal ridge is inadequate for the placement of implants. The sinus elevation procedure provides a way to increase the amount of available bone and to allow the placement of longer implants. Materials & methods: We studied 11 patients requiring the implant placements and the maxillary sinus elevation simultaneously from 1996 to 2003 in our clinic. Nine patients were males and two patients were females, aged from 39 to 72(mean=51.6). Four patients had medical compromised states; angina pectoris, diabetes, hypertension, hepatitis. Patients didn't show any pathologic findings clinically or radiographically. We studied the success and survival rate of implants, factors increasing the osseointegrating capacity of implants. Results: The success rate of osseointegration of implants was 93%. At least 6 months after loading on implants, the survival rate of implants was 78.5%. Autogenous bone graft and adequate residual bone height(>6mm) increased survival rate of implants. Conclusion: Successful implant placement with maxillary sinus elevation mainly depends on sufficient residual bone height, healthy maxillary sinus, autogenous bone graft.

Nowadays, environment pollution caused by development of industrial society becomes a serious social problem. So, ozonized gas is suggested as a counter plan against the problem. In this paper, a double cylindrical type ozonizer has been designed and manufactured to improve ozone yield by cooling external electrode. The ozonizer equipped with three electrodes(central, internal and external electrodes) and two gaps. Discharge and ozone characteristics are described in this paper by varying flow rate( Q ) of oxygen suppling gas, temperature of cooling gas and supplied voltage.

A recombinant human erythropoietin (rHuEPO) was administered intravenously at dosage levels of 0, 100, 500, and 2500 IU/㎏/day for a period of 13 weeks. There were no observed clinical signs and deaths related to treatment in all groups tested. Decreases in body weight gain and food consumption were observed only in males of 2,500 IU/㎏ group after 2 weeks. In hematological parameters, erythrocyte content, hematocrit values and hemoglobin concentration were dose-dependently increased in rHuEPO treated groups. The ratio between kidney weight and whole body weight was significantly increased in females of 500 and 2,500 IU/㎏ groups. The spleen weight was also increased in both sexes of 500 and 2,500 IU/㎏ groups. However, the absolute weight change of other organs was not observed. In histopathological examinations, the renal tubular basophilia was observed only in males and females of 2,500 IU/㎏ groups. From these results, it is concluded that the no-observed adverse effect level(NOAEL) of rHuEPO is 100 IU/㎏ in rats in the present study.

This study was carried out to investigate the purification effect of wastewater included LAS by electrolysis treatment system. Wastewater included LAS treated electrolysis treatment process, temperature of inner treated system were high than those of this raw wastewater, temperature change was electrolysis oxidation of LAS wastewater both cathode and anode. Electrolysis oxidation was oxidized LAS by oxidants of chlorine and ozone, on the time, according to the result development of treated efficiency on electrolysis contact time.

The purpose of this study was to investigated the physics-chemical characteristic of municipal solid waste generated in the Chinju city. It is important to know the physico-chemical characteristic of municipal solid waste. The average physical composition of municipal solid waste in APT and Detached Dwelling are food waste 68% and 55.5%, paper 13.5% and 16.5%, vinyl & plastic 13.7% and 16.5%, glass 2.73% and 1.7%, metal 2.06% and 1.03%, others 6.6% and 2.1%, respectively.
