This is one case report of coexisting two histologically different carcinomas in the different lobes of the right lung, which operated the right pneumonectomy in the Dept. of Thoracic and Cardiovascular Surgery Hanyang University Hospital. The 43 years old male patient complained coughing, blood tinged sputum and weight loss. The chest films [PA and lateral view] showed a small round hazy shadow in the posterior segment of the right upper lobe and irregular hazy densities in the right middle lobe and hilar area. Histopathologically, the tumor in the posterior segment of the right upper lobe was consisted of a tissue of adenocarcinoma and the tumor in the right middle lobe was consisted of a tissue of well-differentiated bronchial squamous cell carcinoma.

With a purpose to manufacture an onion peeler, the root cutting equipment of the onion could be attached to a prototype onion peeler was developed. Before the experiment, the distribution of the dimensions of the Korean native onion were measured. And some types of the blades to cut and remove the root of the onion were designed and such characteristics as feasible revolution, conveying speed, and power requirement were investigated. From the result of the test, the selected one among the various cutters was the wing type blade with the round blade to cut out the root and with the vertical blade to cut a circular line. The optimum operating conditions of the wing type blade were revealed the revolution with no load was at 630 rpm, and the conveying speed was 0.08 m/s. Under these conditions, the maximum torque was 5.25 kg·m and the power requirement was 33 W, respectively.

Pleurotus eryngii(King oyster) is one of the most promising mushrooms being produced on the domestic farms. The quality as well as quantity of Eryngii is sensitively affected by micro climate factors. To safely produce high-quality Eryngii all the year round, it is required that the environmental factors be carefully controlled by well designed structures equipped with various facilities and control systems. This study was carried out at the commercial mushroom cultivation houses to find out reasonable range of each environmental factor and yield together with economic and safe structures influencing on the optimal productivity of Eryngii. This experiment was conducted from Nov. 10, 2004 to Aug. 27, 2005 in Eryngii. cultivation houses. The environmental factors measured for this study were inside/outside temperature, relative humidity and $CO_2$ concentration in Pleurotus eryngii medium. In addition, the yield and quality of mushroom were made investigation. But the optimal productivity will be evaluated by considering the quality and quantity of mushroom production, energy requirements, facility construction and management cost, etc.

Rhabdomyosarcomas are found mainly in young patients, but rare in adults. A correlated cytological and histologic study of one case of embryonal rhabdomyosarcoma is presented. The cytologic appearance of the urine smear corresponded well with the histologic findings. Cytologically, two main cell types were distinguished ; a predominant primitive, small round cell with scant cytoplasm and a large cell with abundant cytoplasm. The cytologic feature proving rhabdomyoblastic differentiation, such as cross-striation, was absent.

Following the prior studs regarding that 1.0g of cotton fabric round be dyed uniformly with a reactive dye in the solvent mixture of $2m\ell$ of water and $23m\ell$ of dichloromethane, silk fabric was dyed with C. I. Reactive Blue 203 in the water/dichloromethane two-phase immiscible solvent media. In order to minimize dye loss due to its hydrolysis, the reactive dyeing was carried out in dichloromethane containing a small amount of water. With only $3m\ell$ of water in $22m\ell$ of dichloromethane, 1.0g of silk fabric could be dyed perfectly. The uptake ratio was increased greatly, compared wish that of normal reactive dyeing in a water medium. It would seem that the one of hydrophobic solvents, dichloromethane, can assist the Even dyeing as it disperses a small amount of dye-dissolved phase and conveys this water phase to the fabric entirely and uniformly.

One specimen (181.0 cm; TL, total length) of Echinorhinus cookei was collected from Busan, Korea in 2014 using gill net. Echinorhinus cookei was characterized by having no anal fin, no spine at dorsal fin and numerous small dermal denticles at the placoid scale. This species is very similar to the congeneric species, E. brucus, but differed in the shape of placoid scale (star in E. cookei vs. round in E. brucus) and distribution of placoid scale (separated in E. cookei vs. slightly overlapped in E. brucus). We adopted the Korean name, Ga-si-bi-neul-sang-eo, for E. cookei, after Kim and Ryu (2017).

Rice callus was treated with 0.56M sucrose solution mixed with 5% pectinase and 10% cellulase, and the protoplasts isolated were transferred to 0.25 M sodium nitrate to induce protoplasmic fusion. Callus tissues were macerated well and degradation of cell walls also proceeded satisfactorily. When the protoplasts were transferred to sodium nitrate solution, many giant roundish protoplasts and some multilobed complex protoplasmic bodies were observed. Most of the fusions took place immediately after the protoplasts were transferred to sodium nitrate. Some multilobed protoplasts which failed to fuse in the initial stage took longer time, about two hours, to get completely fused and rounded-off. Multilobed protoplasmic bodies were invariably multinucleate, while giant round protoplasts had either several nuclei or had one nucleus of large size. Nuclear fusion, also, seemed to occur immediately after the protoplasts were transferred to sodium nitrate.

The purpose of this study was to classify women's face types by visual distinction and to analyze the measurement of face types. A survey was conducted by subjects of 167 women's college students in Kwangju City and Chonnam area. Data were analyzed by Frequencies, Mean, one way ANOVA and Ducan's Multiple Range Test. The major results were as followed ; ·Women's face types were classified by 7 types and there were oblong shape(28.3%), egg shape(25.7%), round shape(23.9%), square shape(12.4%), inverted triangle shape(5.3%), diamond shape(3.5%), triangle shape(0.8%) in the subjects. ·From the measurements of the women's face, index of face length to face breadth was 1.38, it means that the index was different from the other refferences. And the lower face length was longer than the upper and the middle face lengths. ·Differences From those measurements like forehead breadth, face length/bizigion breath(p〈.001), bizigion breadth, bignathion slopper, stature(p〈.01) and trichion breadth, tragion-menton length(p〈.05) were significant in the classified face types.

We experienced a case of giant arachnoid granulation misdiagnosed as dural sinus thrombosis. A 66-year-old woman presented with a one month history of progressive occipital headache. Computed tomography angiography and cerebral angiography showed a round filling defect at the transverse sinus which was speculated as a transverse sinus thrombosis. Anticoagulation therapy was performed to prevent worsening of thrombosis for 2 weeks and then a Gadolinium-enhanced magnetic resonance imaging scan was performed. The filling defect lesion at the transverse sinus revealed a non-enhancing granule with central linear enhancement, which was compatible with giant arachnoid granulation. We checked the intrasinus pressure difference across the lesion the through the dural sinus in order to exclude the lesion as the cause of headache. Normal venous pressure with no significant differential pressure across the lesion was noted. Headache was treated with medical therapy.

The roll Pass design is one of the most important processes to design the whole equipment of the rods and bars rolling system. In this study, the roll pass design program named TollRo(Rolling Factory Organizer) was developed. conventional methods to design roll pass were analyzed and a new algorithm to design the dimension of the intermediate groove was introduced. Object oriented programming technology was implemented in this design program. It comprises GUI(Graphic User Interface), function of automatic pass design, function of modifying pass schedule and database of material properties. The developed program can be used to design roll pass with consistency for the rods and bars rolling system. The man-hours for the whole design can be drastically reduced. The design parameters of rolling system can be extracted quickly by this program.
