A 25-year-old female patient was adimitted due to discomfort in the right chest and left epigastric area. Chest X-ray and chest CT showed a round 4$\times$4$\times$4cm sized mass located in the right lower lobe and abutted on the right diaphragm and metastatic lesions in the right lower lobe and right middle lobe. In exploratory thoracotomy, we discovered a mass originating from the right diaphragm which directly invaded the right lower lobe and metastatic subpleural lesions in the right lower lobe and right middle lobe. The mass was diagnosed as sarcoma by frozen section biopsy and we removed the mass by on bloc resection of the right diaphragm and right lower lobe. Metastatic subpleural lesions in the right lower lobe and right middle lobe were removed by wedge resection. The mass was malignant fibrous histiocytoma of the diaphragm in permanent pathologic examination and chemotherapy was done as adjuvant measure. We report one extremely rare case of malignant fibrous histiocytoma of the diaphragm with literature.

Effects of translocation on seed yield and carbon-nitrogen compounds at five leaf-pod ratios of soybean [Glycine max. (L.)Merr. ] culti bars, 'Paldalkong', 'Baekunkong', and 'Danyeobkong' were measured. The upper 50 and lower 50% of leaves and pods were subjected to treatments at growth stage R3. Three soybean cultivars showed the similar trends on changes in dry matter accumulation and on the contents of soluble sugar, starch and protein in seeds among the treatments. Mean stem dry weight was increased with upper leaf-lower pod and lower leaf-upper pod removals, and decreased with upper leaf and lower leaf removals. Leaf dry weight was appeared higher at the upper leaves among the treatments. Seed numbers and dry weights were decreased with leaf and leaf-pod removals, and were higher in lower part of the plants. Soluble sugar and starch contents in seeds were also showed slightly higher in lower part. Protein content of seeds was decreased in upper part with upper leaf removal and in lower part with lower leaf removal, however, that of the upper seeds was the highest with lower leaf removal. The results of this study are assumed that carbon and nitrogen compounds were translocated opposite directions and protein source was weak in remobilization for the long distance transport during the reproductive growth period of soybean plants.

Hayeob pigment is known as one of the traditional dark green pigments, but the color, raw material, and manufacturing method have not been clearly identified. However, comparing the analysis results of the particle shape and constituent minerals of Hayeob pigments revealed through pigment analysis studies of colored cultural properties such as Dancheong, Gwaebul, and paintings, Hayeob pigments appear to be the same as Dongrok pigments produced by salt corrosion. Therefore, in order to restore Hayeob pigment, the manufacturing method of Dongrok pigment was studied based on the records of old literature. The Dongrok pigment manufacturing method confirmed in the old literature records is a natural corrosion method in which copper powder and a caustic are mixed and then left in a humid condition to corrode. Based on this, artificial corrosion using a corrosion tester was adopted to corrode the copper powder more efficiently, and an appropriate mixing ratio was selected by analyzing the state of corrosion products according to the mixing ratio of the caustic agent. In addition, the manufacturing method of Dongrok pigment was established by adding a salt removal process to remove residual caustic agents and a purification process to increase chroma during pigment coloring. The prepared Dongrok pigments have a bluish green or green color, show an elliptical particle shape and a form in which small particles are aggregated, and a porous surface is observed. The main constituent elements are copper(Cu) and chlorine(Cl), and the main constituent mineral is identified as atacamite [Cu₂Cl(OH)₃]. As a result of an accelerated weathering test to evaluate the stability of the prepared Dongrok pigments, it was found that the greenness partially decreased and the yellowness significantly increased as deterioration progressed. Before deterioration, the Dongrok pigments had lower yellowness compared to the Hayeob pigments of the old Dancheong, but after deterioration, yellowness increased significantly, and it was found to have a similar chromaticity range as Dancheong's Hayeob pigments. As a result, the prepared Dongrok pigments were confirmed to be similar to Dancheong's Hayeob pigments in terms of color as well as particle shape and constituent minerals.

Bronchoesophageal fistula is a rare clinical entity whether congenital or acquired in adult. We experinced 8 cases of bronchoesophageal fistula and performed surgical correction from 1991 to 1994. Of the 8 patients, 5 patients were male and three were female aging from 21 to 61 years(mean 44.12$\pm$14.62 years). Seven of 8 patients had congenital bronchesophageal fistula and the other one had acquired bronchoesophageal fistula. According to the classification of Braimbridge and Keith, 4 cases were belonged to type I and 3 cases were type II . The diagnosis was confirmed by esophagogram in six patients, by bronchoscopy and bronchogram in two patients, and in one patient, the fistula was discovered i cidentally during operation. All patients received astulectomy and concomitant procedures were applied as follows ; 4 diverticulectomy, 4 right lower lobectomy, 1 bilobectomy, 1 left lower lobectomy and 1 wedge resection of left lower lobe. All but one patient were discharged without any complication and have been in good condition.

This research was carried out to elucidate the photosnthesis, respiration, and intercellullar $CO_2$ concentration of Kalopanax pictus leaves. The results obtained are summarized as follows; 1. The light compensation points in leaves of Kalopanax pictus seedlings were in the following order; the upper ($34{\mu}mol\;m^{-2}s^{-1}$) middle ($29{\mu}mol\;m^{-2}s^{-1}$) lower leaves ($24{\mu}mol\;m^{-2}s^{-1}$). The light saturated points were at $800{\sim}1200{\mu}mol\;m^{-2}s^{-1}$ in the upper leaves and $400{\mu}mol\;m^{-2}s^{-1}$ in the middle and lower leaves. At the light saturated points, the net photosynthesis rate was in the following order; the upper ($11.1{\mu}mol\;CO_2\;m^{-2}s^{-1}$) middle ($5.15{\mu}mol\;CO_2\;m^{-2}s^{-1}$) lower leaves ($4.01{\mu}mol\;CO_2\;m^{-2}s^{-1}$). The light use efficiency was in the following order; the upper ($0.041{\mu}mol\;CO_2\;{\mu}mol^{-1}$) middle ($0.040{\mu}mol\;CO_2\;{\mu}mol^{-1}$) lower leaves ($0.039{\mu}mol\;CO_2\;{\mu}mol^{-1}$). 2. In the upper leaves of Kalopanax pictus seedlings, the stomatal conductance increased continuously with increasing light intensity. In the middle and lower leaves, it was saturated at $400{\mu}mol\;m^{-2}s^{-1}$. 3. In the upper, middle and lower leaves of Kalopanax pictus seedlings, the intercellular $CO_2$ concentration/the atmospheric $CO_2$ concentration ($C_i/C_a$) ratio rapidly decreased to $600{\mu}mol\;m^{-2}s^{-1}$, and then showed a constant values. 4. In the upper leaves of Kalopanax pictus seedlings, the photorespiration rate was $3.34{\mu}mol\;CO_2\;m^{-2}s^{-1}$ and $CO_2$ compensation point was $48.7{\mu}mol\;mol^{-1}$. Dark respiration rate increased exponentially with increasing leaf temperature, and the photorespiration rate was 2.4 times higher than dark respiration rate.

Pulmonary arteriovenous malformations (PAVMs) are direct communications between pulmonary arteries and pulmonary veins, resulting in right-to-left shunts that may cause cyanosis, dyspnea, and digital clubbing. Neurological complications such as intracerebral hemorrhage or brain abscess may result from cerebral thrombosis or emboli. In most cases, they remain unrecognized until the late teenage years. Here, we report a case of a 6-year-old boy who presented with perioral cyanosis, digital clubbing, and dyspnea on exertion. A plain chest X-ray showed a focal nodular opacity in the right lower lobe (RLL), and a diagnosis of a large PAVM in the RLL was confirmed by chest computed tomography. A right lower lobectomy was successfully performed without any complications. Although their incidence in children is low, PAVMs should be suspected as a possible cause of cyanosis and dyspnea of non-cardiac origin, and should be treated promptly to prevent further neurological complications.
