A number of authors have reported tissue expansion in the reconstruction of congenital microtia. Tissue expansion has been proved to be particularly applicable in this deformed group because of obviating distortion of the hairline and the need for skin graft in postauricular sulcus, and also because the expanded skin from the postauricular sulcus, and also because expanded skin from the postauricular sulcus, and because expanede skin from area is thin, pliable, well vscularized and non hair-bearing. We have reported 16 cases in which we have used the tissue expander of which the mandral volume is almost 35cc in the reconstruction of congenital microtia from July, 1989 to February, 1990. The reconstructed auricle is satisfactory in it's color, texture and sensation.

Pork from Jeju black pig (population J) and Berkshire (population B) has a unique market share in Korea because of their high meat quality. Due to the high demand of this pork, traceability of the pork to its origin is becoming an important part of the consumer demand. To examine the feasibility of such a system, we aim to provide basic genetic information of the two black pig populations and assess the possibility of genetically distinguishing between the two breeds. Muscle samples were collected from slaughter houses in Jeju Island and Namwon, Chonbuk province, Korea, for populations J and B, respectively. In total 800 Jeju black pigs and 351 Berkshires were genotyped at thirteen microsatellite (MS) markers. Analyses on the genetic diversity of the two populations were carried out in the programs MS toolkit and FSTAT. The population structure of the two breeds was determined by a Bayesian clustering method implemented in structure and by a phylogenetic analysis in Phylip. Population J exhibited higher mean number of alleles, expected heterozygosity and observed heterozygosity value, and polymorphism information content, compared to population B. The $F_{IS}$ values of population J and population B were 0.03 and -0.005, respectively, indicating that little or no inbreeding has occurred. In addition, genetic structure analysis revealed the possibility of gene flow from population B to population J. The expected probability of identify value of the 13 MS markers was $9.87{\times}10^{-14}$ in population J, $3.17{\times}10^{-9}$ in population B, and $1.03{\times}10^{-12}$ in the two populations. The results of this study are useful in distinguishing between the two black pig breeds and can be used as a foundation for further development of DNA markers.

In a small island community with a population of less than 100 residents, nine persons died and five experienced severe illnesses during the period from November 1986 to May 1988. Their initial symptoms were sore throat and fever. Renal failure and hepatitis developed within one week after the onset. Oral mucosal ulcer developed in some cases. After one week, progressive respiratory failure and dyspnea developed evidently and severe respiratory distress and hypoxia preceded those fatal cases. Chest X-ray findings revealed bilateral diffuse multiple cystic lesion with occasional multiple large emphysematous bullae. Based on these features paraquat poisoning was diagnosed and route of poisoning was investigated. In three sources of drinking water, trace amount of paraquat was detected in November 1988, six months after the incidence of recent fatal case. In November 1988, soybean sauces and soybean pastes from 12 households were found contaminated with high concentration of paraquat, the cause could not be identified. The possibility of the contamination of drinking water as the cause of this mass poisoning has been suggested.

유기오리의 도체중은 일반오리보다 품종 및 사양방법의 차이에 기인하여 낮게 나타났으나 도체율에서는 큰 차이가 없었다. 가슴부위의 정육율에서는 일반오리(11.95%)보다 높게 나타났으며, 다리부위(13.07%)에서는 일반오리(14.2%)보다 다소 낮게 나타났으나 유의적인 차이는 보이지 않았다(p<0.05). 도축 직후 측정된 유기오리의 pH는 가슴 및 다리부위에서 각각 6.48 및 6.73으로 일반오리보다 높게 나타났는데 일반적으로 다리부위의 pH값이 가슴육보다 유의적으로 나타났다(p<0.05). 유기오리육에서 다리근육이 가슴근육 보다 낮은 가열감량을 나타내었다. 따라서 유기오리에 대한 일반 이화학적 검사 결과 일반오리육보다 높은 pH, 높은 전단력, 낮은 가열감량 등이 우수하였다. 관능검사 결과 육질 및 냄새, 연도, 맛에 있어서 일반오리보다 좋은 기호도를 보였으며 이와 같은 결과 전체적으로 우수한 식육 자원으로서 육제품 개발에도 충분한 가치가 있는 것으로 사료된다. Organic duck's carcass weight was lower than general duck's because of the differences in breed and feeding method, but there was no difference in carcass percent among them. The rate of organic duck's fresh breast meat(17.62%) was significantly higher than that of general duck's(11.95%)(p<0.05). The rate of fresh leg meat rate was lower in organic duck, but there was no significant difference among them(p>0.05). The pH of breast and leg measured immediately after butchering were 6.48 and 6.73 in organic duck, respectively and there was significant difference among them(p<0.05). According to the sensory test, the texture, odor, tenderness, and taste showed better preference in organic duck than those of broiler chicken. According to above physicochemical analysis and sensory test, organic duck showed higher pH, higher shear force, and lower cooking loss. Therefore, it is considered to be very valuable to develop the exploitation of meat product in organic duck which had good quality and tastiness.
