This study is to investigate the implication of Donald Winnicott's theoritical concept, "marternal caring environment" through the traditional method of infant feeding and caring in Korea. The method of this study is literature research. First, to examine the traditional method of i7ant feeding and caring in Korea, it refered to korean documents in the Chosen dynasty involving 「Dong Eu Bo Gam」 「Gyu Hab Chong Seo」, and 「Traditional Child Rearing Method」 which was united Korean sundry records about child rearing. Second, to study Donald Winnicott's "maternal caring environment", it refered recent volumes about Donald Winnicott and his theory. They are 「The boundart and space」, 「Play and reality」, 「Psychoanalytic object relation theory」, 「Maturational Processes and the facilitating environmen」. The results of this study are as follows. It was found that the traditional method of infant feeding and caring in Korea is connected with D. Winnicott's "maternal caring environment". First, traditional method of infant feeding is connected with "Holding", "Handling", Object offer and omnipotence experience" and "Mirror-role of Mother (or Mirroring)". Second, traditional method of infant caring is connected with "handling" "Mirror-role of Mother". Conclusively, It was confirmed that our traditional infant raring method is rational and precursive on a viewpoint of modern developmental psychology.

The purpose of this article is to confirm the longterm biocompatibility of national Avana implant and international ITI implant in dogs. At the fourth month after extreaction of the mandibular third and fourth premolar in three dog, both implants were inserted using careful atraumatic technique and prosthetic abutments were applied onto the implants in three months. After that, the implants were examined by naked eye and radiographic image every three months during 1 year, for detection of the complications, such as, mobility, bone resorption and wound infection. At 1 year after application of prosthetic abutment, the dogs were sacrificed for the histopathologic analysis by light microscope. The results obtained were as follows; 1. All implants had the ralatively good prognosis without mobility, wound infection and moderate bone resoprtion, in clinical and radiological evaluation during one year. 2. The all histopathologic specimens at one year after application of prosthetic abutment onto the implants showed the distinct osseointegration between implant system and bone, with projection of new bone apposition onto the peri-implant tissue. But Avana implants had the less osseointegration than ITI implants in the cancellous and marrow layer of jaw bone. 3. The all histopathologic specimens at one year after application of prosthetic device showed the firm junction by dense connective tissue pattern between the implant and the gingival portion. But Avana implants had the less firmer junction than ITI implants. 4. The authors confirmed that Avana implant and ITI implant have more higher tissue biocompatibility in dental implantation, but ITI implant has the more osseointegration than the Avana implant.

Treatment of compound alveolar bone fracture consists of reduction and fixation with wound closure of soft tissue laceration. For the proper reduction and fixation, interosseous wiring or splinting of the involved teeth are applied during about 4 weeks. But wound infection around the fracture site may be occurred, because of the presence of devitalized tissues(pulp, bone and soft tissue), residual hematoma and anergy effect of trauma stress. The wound infection results in bone resorption, pulp degeneration and necrosis, wound dehiscence and soft tissue necrosis around the fracture site. Therefore, if the infection will be expected, early proper drainage should be established via the fracture site and root canal of the luxated teeth. The authors treated two cases of compound alveolar bone fracture by the rubber drainage in the fracture site and the endodontic drainage by open canal of the luxated teeth, with the usual reduction and fixation by use of arch bar and resin. The prognosis was more favorable without wound infection, bone resorption, teeth mobility and specific root resorption.

This research was undertaken in order to obtain the basic data for systematical pig management through of pig analysis of current status of raising pigs, wholesale price, the appearance ratio of carcass grade, consumption of pork, the number of pigs imported and exported during about 10 years in Korea. These data were collected and analysed from recent secondary raw data. The results obtained were abstracted as follows; 1. The number of raising pigs have tendency to increase gradually with about 8,371,000 pigs, while the number of farm household have tendency gradually to decrease with 24,000 household on September, 2000. Accordingly, the farm sizes are changing with large scale of average of 349 pigs. 2. The farm price of alive pig at 100㎏ was high level with 199,000won in 1999. The carcass price per 1㎏ was the average of 2,982won in 1999. The pork was consumed much more in summer season. 3. The total of meat consumption per capita have been increasing with 30.54㎏ in 1999. Out of total meat, pig meat was 53%. 4. The live pigs imported had been increased gradually up to 1997, however, decreased with 410 heads in 1998. The pigs imported have been mainly utilized as effective breeding animals. 5. The pork imported has been showing rapid increment since 1997. Otherwise, the pork has been gradually decreased with 55,684ton in 1998.

The study was carried out in order to investigate the genetic polymorphism of serum protein, Albumin(Al) and Transferrin(Tf) through polyacrylamide gel electrophoresis (PAGE) in native Hanwoo. Blood samples were collected and examined from a total of 90 cattle raising in Yesan district in Chungnam province. The results obtained were as follows; 1. The distributions of genotype for Al AA and Al AB at Al loci were 96.7%(87 heads), and 3.3%(3 heads), respectively. The homozygous genotype, Al BB was not detected in this experiment. 2. The frequencies of genes for AlA and AlB were 0.983 and 0.017, respectively. Therefore, these population of Hanwoo group had been maintaining genetic equilibrium (P>0.05). 3. The distributions of genotype for Tf AA, Tf AD1, Tf AD2, Tf AE, Tf D1D1, Tf D1D2, Tf D1E Tf D2D2 Tf D2E, and Tf EE were 10.0%, 23.3%, 20.0%, 6.7%, 6.7%, 13.3%, 6.7%, 3.3%, 6.7%, and 3.3%, respectively. 4. The frequencies of genes for TfA, TfD1, TfD2, and TfE were 0.350, 0.284, 0.233, and 0.133, respectively. 5. Al loci were supposed to be controlled by to autosomal codominant allelic genes such as AlA and AlB. However, Tf loci were assumed to be controlled by four codominant allelic genes as TfA, TfD1, TfD2, and TfE.

황남철,최문석,이준혁,고광철,백승운,유병철,이종철,이광웅,조재원,박철근 대한간학회 2004 Clinical and Molecular Hepatology(대한간학회지) Vol.10 No.2

목적: 간의 국소 결정성 과형성은 일반적으로 특별한 치료가 필요 없는 양성 종양이다. 그러나 드물지만 합병증이 발생한 경우와 진단이 불확실한 경우에는 수술을 시행하게 된다. 이에 저자들은 간절제술을 시행한 국소 결절성 과형성의 임상적, 영상학적 특징들을 알아보고자 하였다. 대상과 방법: 1995년부터 2003년까지 수술을 시행하여 조직을 확인한 국소 결절성 과형성 환자 10명을 대상으로 연령, 성별, 실험실 검사 및 영상 소견과 조직 소견을 분석하였다. 결과: 연령의 중앙값은 37.5세, 남녀 비는 1.5:1이었다. 5예에서는 간세포선종이나 간세포암종을 감별할 수 없어서 수술을 시행하였으며, 수술 후 우연히 진단된 예는 4예이었다. 간세포암종의 위험 인자를 가지고 있었던 예는 4예(B형 간염 바이러스 보유자 3예, 간경변 2예)이었다. CT검사가 시행되었던 6예 중 5예는 동맥기에서 조영 증강을 보였고 문맥기 및 지연기로 감에 따라 주변과 동일(4예)한 또는 감소(2예)되는 양상을 보여 간세포암종과의 감별이 어려웠다. 크기는 3.2±2.2㎝이었으며 위치는 간우엽의 후하구역(S6)에 가장 많았다(30.0%). 4예에서 수술 전 침생검을 시행하였으나 고분화 간세포암종이나 간세포선종과의 감별이 어려웠다. 결론: 임상상, 영상검사 및 간침생검으로도 간세포암종이나 간세포선종과의 감별이 어려운 경우 수술을 시행하였으며 수술 전에는 발견하지 못하였지만 다른 질환으로 인한 수술시 우연히 발견된 경우도 있어 국소 결절성 과형성의 수술 전 진단이 어려운 경우가 적지 않음을 알 수 있었다. Background/Aims: Focal nodular hyperplasia (FNH) is a benign hepatic tumor with few serious complications and no malignant transformation. However, differential diagnosis between FNH and other liver tumors, especially hepatocellular carcinoma, is often difficult. Methods: Clinical features of surgically resected FNH were reviewed. From January, 1995 to February, 2003, 10 patients with surgically resected FNH were enrolled. Their age, sex, results of laboratory examination, imaging studies and pathologic findings were evaluated. Results: Median age was 37.5 years and sex ratio (male:female) was 1.5:1. In 5 cases, resection to exclude hepatic adenoma or HCC was performed. Four cases were diagnosed incidentally after surgery. Four patients had risk factors for HCC, such as hepatitis B virus infection, liver cirrhosis or both. The size of FNH was 3.2 2.2 cm. The most common site of the tumor was segment 6 (30.0%). Differential diagnosis with HCC was difficult in 5 of six cases in whom CT was performed. Although needle biopsies were performed preoperatively in 4 cases, it was difficult to distinguish FNH from hepatic adenoma or HCC. Conclusions: FNH was resected due to uncertainty of diagnosis, or incidentally during hepatectomy in patients with other liver disease. In the former, differential diagnosis with hepatic adenoma or HCC was a major problem despite extensive work-up including dynamic CT or biopsy. (Korean J Hepatol 2004;10:135-141)
