N/A Background/Aims: Recent surgical techniques have enabled surgeons to undertake radical operations for a much wider range of liver diseases, but the invasive nature of such operations requires that they be followed up by careful and intensive postoperative management. Since the introduction of the oxidation-reduction(redox) theory in the beginning of 1980s, the significance of the arterial ketone body ratio(acetoactate/g-hydroxybutylate), which reflects hepatic mitochondria] oxidation-reduction potential, has been discussed as one of the metabolic parameters of organ failure. The aim of this study was to assess the significance of arterial ketone body ratio as an early prognostic indicator in liver surgery. Methods: In this study, arterial ketone body ratio and total ketone body concentration were serially measured in 83 patients who underwent liver resection in the department of surgery of Youngnam University Hospital between May 1992 and Feburary 1994. Results: At the postoperative 1 day, arterial ketone body ratio was significantly higher in successful recovery group(n=71, 1.22 0.59) than that of the postoperative complication and mortality group(n=12, 0.66 l 0.34). And patients were classified into three groups by the decrease of ketone body ratio in the postoperative 1 day: group A(70 cases) with ketone body ratio above 0.7, group B(12 cases) between 0.7 and 0.4, and group C(1 case) below 0.4. In group A, 63 patients(90%) were recovered, 6 patients complicated and 1 patient dead. In B group, 8 patients(66.6%) was recovered, 2 patients complicated and 2 patients dead. The only patient of group C(100%) was dead. Conclusions: Postoperative AKBR is useful as an early prognostic indicator in liver surgery, and maintenance of AKBR above 0.7 is crucial to obtain a good surgical outcome.

Purpose: This study is conducted to investigate the relationships among sports commentators’ attributes, media engagement, and continuous watching intention in consideration of the new media platform era. Method: The survey was conducted on 350 viewers who watched the KBO league online more than once using the Google questionnaire. Of the 350 questionnaires collected, 26 inappropriate questionnaires were excluded, and 324 copies were selected as the final valid sample and used for data processing. Results: First, as a result of examining the relationship between sports commentators’ attributes and media engagement, it was found that among the sub-factors of commentators’attributes, professionalism had a negative effect on media engagement, and reliability had a positive effect. Moreover, attractiveness and technology & smart did not appear to affect media engagement. Second, media engagement was found to have a positive effect on the intention of continuing watching. Conclusion: It is necessary to find a way to make viewers more immersed in sports commentators’ commentary, and ultimately, it is reasonable to think that how to elicit a high level of immersion and empathy for viewers affects actual ratings.

N/A Background/Aims: The liver is a central organ in metabolic and irnmune homeostasis under normal and pathologic condition and its funtion is directed by classic homiones and a network of cytokine mediators. Because the liver has a strong potentiol for regeneration, clarifying its mechanism is a matter of great interest. Although many studies on cytokines are being conducted, its clinical significance in hepatectomy still remains unclear. The aim of this study is to clarify the changes of serum cytokines and to investigate the possible regulation of the cytokine release in hepatectomy. Methods: We studied 55 patients who had underwent hepatectomy in the department of surgery at Yeungnam University Hospital between Septernber 1992 and July 1994. Serum levels of IL-1 0, IL-6, TNF- a were measured before operation and on the postoperative day(POD) 1, 3, 5 and 7. Then those were compared between patients with major resection(more than 2 segments) and minor resection, between patients with cirrhosis and those without cirrhosis, and between patients with recovered without complication and patients recovered with comp]ication or inortality. Results: ln the recovery group, the levels of serum IL-10 reached peak levels at POD # 1 and then gradually decreased, the levels of the serum IL-6 reached peak levels at POD 0 l and re- elevated at POD # 5, but there was no significant change in the serial levels of the serum TNF- a. No significant difference in the serial levels of cytokines(IL-] 0, IL-6, TNF- a ) was found hetween the patients with cirrhosis and those without cirrhosis and between the major resection and minor resection. The levels of cytokines in the complication R mortality group were higher than those of the recovery group. Conclusions; The levels of IL-I 3, IL-6 reached peak level at POD # 1 and gradually decreased to normal levels at POD 0 7 in the recovery group. In the complication & mortality group, the levels of cytokines were higher than those of the recovery group. (Korean J Gastroenterol 1997;29:192-198)

N/A Serum complement levels were evaluated retrospectively in 68 patients with chronic liver diseases: 21 patients with chronic active hepatitis, 25 patients with liver cirrhosis, and 22 patients with hepatocellular carcinoma in liver cirrhosis. There was no significant difference in serum complement levels between the chronic active hepatitis patients and the control group. Serum complement levels were significantly reduced in the liver cirrhosis group compared with the chronic active hepatitis and normal control groups, while hepatocellular carcinoma in the liver cirrhosis group showed significantly high serum complement levels compared with the liver cirrhosis only group. Serum C3 levels correlated well with the serum albumin levels and prolonged prothrombin times in chronic active hepatitis and liver cirrhosis patients but not in the hepatocellular carcinoma patient group. The cutoff values of the complements for detection of hepatocellular carcinoma in patients with liver cirrhosis were set according to a retrospective study. Based on these data, a prospective study was performed to detect hepatocellular carcinoma in 58 patients with liver cirrhosis. The positive predictive values, negative predictive values, and accuracies of the complements were as follows: 83.3%, 79.4%, and 81.0% for C3, 87%, 80.0%, and 82.8% for C4 respectively. Thus, these data suggest that measuring serum complement levels may be helpful in the follow-up evaluation of patients with chronic liver diseases, and the combination of complements tests and α-fetoprotein test could be useful in the early detection of hepatocellular carcinoma in liver cirrhosis patients.

Expressways are often upgraded by widening the lanes and/or by reshaping the roads to be more linear for faster travel time. However, during the process of improving the route of the expressways, the areas where the old expressways used to be are often unused and abandoned. When these neglected sites are left alone, they often become dump sites causing pollution and impacting the surrounding environment. Therefore, it is important to restore the abandoned expressway sites to its full natural beauty. In this study, the abandoned expressway at the Soksa interchange in Pyungchang county, located in Kangwon province was studied for establishing the model of ecological restoration project. Considering the characteristics of the site, the target flora species was chosen to be Quercus species and the target fauna species as amphibians. After the target species were carefully chosen, each species` habitat requirements were studied in order to figure out the appropriate methods toward habitat restoration specifically for these species. In addition, to determine the most efficient method toward restoration of abandoned expressways, the study utilized the planting hole techniques, the crack techniques, and the colonization techniques. In terms of the spatial organization, public education program is incorporated at the main entrance area and the programs for experimenting, and developing vegetation and habitat restoration techniques are placed in the vicinity. In the master plan-to provide natural ecosystem at the site-ASCON (asphalt concrete) was removed first, then plans for restoration including species` habitat restoration were established. Furthermore, the project included plans for improving water quality polluted through non-point source considering the surrounding nearby road and farm lands. Finally, the study established a planning process that will experimentally apply to the abandoned expressway restoration method. In the future, there will be a continuous monitoring of the methods applied to verify if the restoration methods are effective. Also, new restoration techniques should be available according to a variety of abandoned expressways` characteristics.

목적: 대장암은 유전 소인, 흡연, 음주, 식습관 등의 환경인자가 작용하여 발생하며 또한 비만, 고지혈증, 고혈당, 고인슐린 혈증 및 인슐린 저항성이 대장암의 발암과정과 연관이 있다. 다양한 비만 지표를 이용해서 대장 선종과 비만 및 인슐린 저항성과의 연관성을 알아보고자 하였다. 대상 및 방법: 2004년 1월부터 2004년 10월까지 한양대학병원에서 검진 목적으로 대장내시경검사와 기타 검사를 시행 받은 환자를 대상으로 전향적으로 환자 대조군 연구를 시행했다. 크기가 0.5 cm 이상이며 조직학적으로 대장 선종이 증명된 50명의 환자를 대상으로 했으며, 대조군은 동일 기간 중 대장내시경검사를 시행 받았으나 특이 병변이 없었던 자로 정했다. 결과: 인슐린, 공복혈당, 총 콜레스테롤, triglyceride, LDL, HDL 수치, 수축기 및 이완기 혈압은 환자군에서 모두 증가되었으나 환자군과 대조군 사이에 유의한 차이는 없었다. HOMA-IR은 환자군에서 인슐린 저항성 수치가 높았으나 통계적인 유의성은 없었다. 그러나 체질량지수, 복부 비만, 체지방, 비만도는 환자군이 대조군 보다 유의하게 높았다. 다변량 분석에서 복부 비만이 가장 의미 있는 위험 인자였으며 체질량지수가 증가함에 따라 대장 선종의 위험도도 증가했다. 체지방, 비만도 역시 중요한 위험 인자였다. 결론: 비만과 대장 선종의 연관성에서 복부 비만이 가장 중요한 위험 인자였으며 복강 내 지방조직이 중요한 역할을 할 것으로 기대한다. 향후 대규모의 환자 대조군 및 코호트 연구가 필요하며 복강 내 지방의 역할에 대한 분자생물학적인 연구가 필요하다. Background/Aims: Abdominal obesity and hyperinsulinemia or insulin resistance are of interest in connection with colon carcinogenesis. We conducted a prospective case controlled study for the evaluation of relationship between abdominal obesity, insulin resistance, and colorectal adenoma. Methods: Fifty patients with colorectal adenoma and fifty healthy subjects were included in this study. Total colonoscopic examinations were performed in all the subjects. Fasting blood sugar (FBS), insulin, homeostasis model assessment (HOMA-IR), triglyceride (TG), cholesterol (CROL), BMI (body mass index), WHR (waist hip ratio), percent body fat (PBF) and obesity degree (OD) were measured. HOMA-IR was considered to represent insulin resistance. Diabetic patients were excluded from this study. Results: There were no differences in sex, serum insulin, FBS, HOMA-IR, TG, CROL between adenoma and control group. Subjects with high BMI, WHR, percent body fat, and obesity were more likely to have colonic adenoma. Multiple logistic regression analysis after adjusting confounding factors, had revealed that WHR was the most important independent risk factor for colon adenoma. Conclusions: Abdominal obesity was most closely related to colonic adenoma. However, insulin resistance was not related to colonic adenoma. A larger case controlled study is needed.
