Korean species of the genus Cleptes Latreille were taxonomically reviewed, and seven species were confirmed. Among them, C. fudzi and C. japonicus were new to Korea, and C. metallicorpus was new to science. A C. seoulensis male was described for the first time. Cleptes nitidulus was tentatively excluded from Korean fauna. A key to Korean Cleptes species, diagnostic descriptions for all treated species and digital images are provided.

Korean species of the genus Elampus Spinola is taxonomically reviewed. Korean fauna of the genus Elampus was known by one sepcies, Elampus bidens (Forster). This study reports new discover of another Korean species E. musashinus (Tsuneki). This species was described based on male, and the female has been still unknown. With comparison of partial mitochondrial cytochrome c oxidase I gene sequences, the sex-association of this species is established, the Korean specimens of both sexes completely identical in their sequences targeted. Herein the female description of E. musashinus is presented for the first time. A key to the Korean species, as well as diagnosis and digital images are provided.

Background: The smoking prevalence in asthma patients are similar to those in the general population. Asthma and active cigarette smoking can interact to create more severe symptoms, an accelerated decline in lung function and impaired therapeutic responses. Accordingly, asthmatics with a history of smoking were examined to define the clinical characteristics and lung function of smoking asthmatics. Methods: The medical records of 142 asthmatics with a known smoking history were reviewed. The patients were divided into three groups according to their smoking history - current smokers, former smokers and non-smokers. The clinical characteristics, lung function, and annual declines of the forced expiratory volume in one second ($FEV_1$) were compared. Results: Fifty-three of the 142 patients (37%) were current smokers, 24 were former smokers (17%) and 65 were non-smokers (45%). The patients with a hospital admission history during the previous year included 16 current smokers (30%), 4 former smokers (17%) and 7 non-smokers (11%) (p=0.02). The mean $FEV_1$ (% predicted) was 76.8${\pm}$19.8%, 71.6${\pm}$21.1% and 87.9${\pm}$18.7% for current smokers, former smokers and non-smokers, respectively (p< 0.001). The $FEV_1$/forced vital capacity (FVC) (ratio, %) values were 63.6${\pm}$12.6%, 59.3${\pm}$14.9% and 72.1${\pm}$11.8% in current smokers, former smokers and non-smokers, respectively (p<0.001). The corresponding mean values for the individual $FEV_1$ slopes were not significant (p=0.33). Conclusion: Asthmatic smokers demonstrated higher hospital admission rates and lower lung function. These findings suggest that the smoking history is an important predictor of a poor clinical outcome in asthma patients.
Characteristics of Fuel Pellets Made by Mixing Paper Sludge and Forest Byproducts

In this study, for reusing the sludge generated in a fine paper mill as fuel, the characteristics of the pellets prepared by mixing auxiliary raw materials such as pulp mill chip rejects, ca- mellia oilseed cake, Sancho pruning remnants, and mulberry pruning remnants were evalu- ated. The pellet yield decreased as more sludge containing about 50% of the inorganic fillers was mixed with each auxiliary material, but the camellia oilseed cake, unlike the others, was of great help in improving the pellet yield. The Van Krevelen diagram showed that, as more sludge was added to the woody biomass in preparing the pellets, they tended to have a simi- lar elemental composition to that of coal or lignite. The sludge addition to the woody biomass had a negative effect on the calorific value of the pellets, but the lower calorific value of 2400-3000 kcal/kg was acquired even when more than 50% of sludge was added. The sludge pellets containing the camellia oilseed cake had a faster ignition point than those mixed with the other woody biomass, but the flame duration was shorter. This study showed that the sludge from fine paper mills containing about 50% of cellulose fibers could be used to pro- duce economical solid fuels if mixed with other woody biomass in an appropriate ratio.

Intramural pregnancy is one of the rarest forms of ectopic pregnancy. The pathologic diagnosis of the intramural ectopic pregnancy requires that the myometrium surrounds the products of conception separated from the endometrial cavity or fallopian tubes.
