In this paper, we study the highest bid price determination mechanism of the court auction markets for apartments that are under distraint because of the insolvency of the owner of the apartments. In addition to the typical variables used in previous literatures on the determination of highest bid price, we add the variables that represent the characteristics of the tenants categorized by the priority order of the tenants’ deposits in the distribution process of the money obtained from the auction of the apartments. Unlike our general perception, the results show that the presence of pretense tenants on the priority list of the distribution of dividend from the auction hardly affects the determination of the highest bid price. In addition, the presence of legal counter power of tenants against the landlord does not affect the highest bid price, either. The first policy implication of this paper is that to set up a fair institutional mechanism in court auction market for apartments under distraint, the auction court needs to ask the applicant of the auction to prove whether the listed tenants are true to eliminate the pretense tenants. The second policy implication is that the court needs to disapprove the seniority of the pretense tenants’ claim on the distribution of dividends from auction of the apartments.

Background: From many previous studies, Pulmonary hypertension is the known independent predictive factor of the mortality in COPD. Also pulmonary hypertension is the major cardiovascular complication of COPD and is associated with the progression to cor pulmonale and poor prognosis. Author want to analyze the correlation between pulmonary hypertension and the severity of COPD which are classified by forced expiratory volume in one second, and the extent of progression to corpulmonale. Methods: Retrospectively we investigated the medical records of 118 patients with COPD who had pulmonary function test and echocardiogaphy more than one times during one-year follow-up (from June, 2005 to May, 2006) at respiratory division in chosun university hospital, and then 50 patients were enrolled in this study. We classified the severity from FEVl in pulmonary function test based on the GOLD guideline, also this was comparably analyzed with RVSP, RVIDd, Visual Grading from echocardiography. Results: 16 patients out of 50 were classified as moderate severity, 25 patients were severe, and 9 patients were very severe group. RVSP was higher in more severe groups than less severe groups but when it comes to pulmonary hypertension that RVSP is over 35 mmHg, there was no valid difference lies in those groups. As FEVl decreases RVSP and RVIDd increases, and observed relationship between RVSP which was classified as below 35 mm and above 35 mm groups and visual grading which was classified as normal and dilatated groups revealed valid correlation, Conclusion: As pulmonary function decreases, progression to pulmonary hypertension and cor pulmonale increases but there was no remarkable difference of prevalence in above moderate severity groups. 연구배경 폐고혈압은 이전의 많은 연구에서 만성폐쇄성폐질환에서 독립적인 사망의 예측인자로 알려져 있다. 또한 폐고혈압은 만성폐쇄성폐질환의 주요한 심혈관계 합병증이며, 폐성심으로의 진행 및 불량한 예후와도 관련되어 있다. 이에 저자는 폐고혈압과 1초간 노력성호기량으로 분류되는 만성폐쇄성폐질환의 중증도 및 폐성심으로의 진행 정도를 비교 분석하여 이들의 상관관계를 밝혀보고자 한다. 방법 2005년 6월부터 2006년 5월까지 1년 동안 본 병원 호흡기 내과에서 폐기능검사와 심장초음파 검사를 각각 1회 이상 시행한 적이 있는 118명에 한하여 의무기록을 후향적으로 조사하여 이 중에서 50명을 대상으로 하였다. 폐기능검사 시행 결과 얻은 1초간 노력성호기량을 바탕으로 GOLD guideline에 따라 중증도를 분류하였으며 이를 심초음파 시행 결과 얻은 우심실수축기압, 확장기말 우심실내부간격, 시각등급과 비교분석하였다. 결과 대상 환자 50명중 16명은 중등증, 25명은 중증, 9명은 최고중증 그룹으로 분류되었다. 우심실수축기압은 중증도가 높은 그룹에서 낮은 그룹에 비해 더 높게 나타났으나 폐고혈압에 해당하는 우심실수축기압이 35 mmHg이상인 환자에 있어사는 각 그룹간에 유의한 차이를 보이지 않았으며, 확장기말 우심실내부간격, 시각등급 또한 중증도와 유의한 차이를 보이지 안항ㅆ다. 1초간 노력성호기량이 감소함에 따라서는 우심실수축기압, 시각등급은 증가하였으며 우심실수축기압을 35mmHg 미만과 이상인 그룹으로, 시각등급을 정상과 확장이 있는 그룹으로 분류하여 비교한 결과에서는 유의한 상관관계를 나타냈다. 결론 폐기능이 감소할수록 페고혈압 및 폐성심으로의 진행이 증가하였으나 폐기능검사에서 중등도 이상의 그룹에서 유병률의 차이는 크지 않았다.

Backgrounds/Aims: Hepatic resection has only guaranteed long-term survival in patients with colorectal liver metastasis (CRLM) even in the era of effective chemotherapy. The definite role of neoadjuvant chemotherapy (NCT) is to improve outcomes of unresectable CRLMs, but it its role has not been defined for initially resectable CRLMs (IR-CRLMs). Methods: We reviewed the medical records of 226 patients, who had been diagnosed and treated for IR-CRLM between 2003 and 2008; the patients had the following pathologies: 10% had more than 4 nodules, 11% had tumors larger than 5 cm, and 61% had synchronous CRMLs. Among these patients, 20 patients (Group Y) were treated with NCT, and 206 (Group N) did not receive NCT according to their physician’s preference. The median follow-up time was 34.1 months. Results: The initial surgical plans were changed after NCT to further resection in 20% and to limited resection in 10% of 20 patients. Complication rates of Groups Y (30%) were indifferent from Group N (23%) (p=0.233), but intraoperative transfusions were more frequent in Group N (15%) than in Group Y (5%) (p=0.006). There was one case of hospital mortality (0.44%). Disease-free survival rates in Groups Y and N were 23% and 39%, respectively, and patient survival rates were 42% and 66% (p>0.05). By multivariate analysis, old age (≥60 years), differentiation of primary tumor (poorly/mucinous), resection margin involvement, and no adjuvant chemotherapy were associated with poor patient survival; the number of CRLMs (≥4) was associated with poor disease-free survival. Conclusions: NCT had neither a positive impact nor a negative impact on survival, even with intraoperative transfusion, as observed on operative outcomes for patients with IR-CRLM. Further study is required to elucidate the role of NCT for treatment of patient with IR-CRLMs. (Korean J Hepatobiliary Pancreat Surg 2011;15:206-217)

Purpose: Hepatic resection is a standard method of treatment for colorectal liver metastases (CRLM). However, the pathologic factors of metastatic lesions that affect tumor recurrence are less well defined in CRLM. The aim of this study was to evaluate the risk factors for recurrence of CRLM, focusing on histopathologic factors of metastatic lesions of the liver. Methods: From January 2003 to December 2008, 117 patients underwent curative hepatic resection for CRLM were reviewed. Tumor size and number, differentiation, tumor budding, angio-invasion, dedifferentiation and tumor infiltrating inflammation of metastatic lesions were investigated. Results: The mean number of hepatic tumors was 2 (range, 1?8). The mean size of the largest tumor was 2.9 cm (range, 0.3?18.5 cm) in diameter. The moderate differentiation of the hepatic tumor was the most common in 86.3% of the patients. Tumor budding, angio-invasion, and dedifferentiation were observed in 81%, 34%, and 12.8% of patients. Inflammation infiltrating tumor was detected in 6.8% of patients. Recurrence after hepatic resection appeared in 69 out of 117 cases (58.9%). Recurrence-free survival at 1, 2 and 5 years were 62.4%, 43.6%, and 34.3%. The multivariate analysis showed the number of metastases ≥3 (P = 0.007), the tumor infiltrating inflammation (P = 0.047), and presence of dedifferentiation (P = 0.020) to be independent risk factors for tumor recurrence. Conclusion: Histopathological factors, i.e., dedifferentiation and tumor infiltrating inflammation of the metastatic lesion, could be one of the risk factors of aggressive behavior as well as the number of metastases even after curative resection for CRLM.
