사학법은 사학의 전반적인 운영과 체제를 정리한 법이다. 사학법 개정과 관련하여 찬성 의견이 많았는데 그 이유로 교육을 사적재산으로 보지 않고 공공적 측면을 중심으로 보는 우리 국민의 특성 때문이라는 지적이 있다. 높은 교육적 관심때문이라는 것이다. 그러나 교육을 공공재로 보는 진짜 이유는 모든 국민에게 '교육의 기회 균등'을 부여하기 위함이다.

우리는 그간 정부 주도의 대학개혁이 소기의 성과를 달성하지 못하고 실패로 끝났던 역사적 사실을 상기해 볼 때 새로운 패러다임은 누군가의 강요가 아닌 구성원들의 합의와 공감대가 형성되었을 때 가능함을 분명히 각인해야 한다.

Combined hepatocellular-cholangiocarcinoma (HCC-CC) with sarcomatoid features is an extremely rare primary liver cancer, of which only four cases have been reported. We report a case of sarcomatoid combined HCC-CC in a 60-year-old woman who complained of right upper quadrant pain and presented with a 7 cm mass in the S4 region of the liver in abdominal CT. Ultrasonography-guided needle biopsy diagnosed it as HCC, and left lobectomy of the liver followed. Microscopically, the tumor consisted of two portions: HCC portion showing trabecular pattern, which had partially sarcomatous area with spindle-shaped tumor cells, and CC portion with glandular pattern. Immunohistochemically, HCC portion reacted positively with α-fetoprotein while CC portion demonstrated positive reactivity with carcinoembryonic antigen and mucicarmine. Sarcomatoid cells reacted positively for cytokeratin. She died of tumor recurrence and hepatic failure 12 months after the operation. Combined HCC-CC has poor prognosis, and sarcomatoid HCC has high metastatic potential and poor prognosis compared with ordinary HCC. (Korean J Gastroenterol 2004;43:56-60)

This study considers a two-machine flowshop scheduling problem for the objective of minimizing total tardiness. In the flowshop, jobs have to be started on the second machine within the limited waiting time after those jobs are completed on the first machine, which is called a limited waiting time constraint, and jobs require sequence-dependent setup times before processing on the second machine. This scheduling problem is modeled in a mathematical programming formulation and the optimal solutions are obtained by CPLEX 12.9. However, solving this problem to optimality by using CPLEX needs a significantly long computation time since this problem is known to be NP-complete, hence heuristic algorithms are proposed to solve the problem within a short computation time. Computational experiments on randomly generated problem instances are done to evaluate the performance of the proposed algorithms and the results are reported.

This study aimed to validate one of the tools for assessing decision-making capacity: the University of California at San Diego`s Brief Assessment of Capacity to Consent (UBACC), which is composed of a 10-item scale that includes questions focusing on the understanding and appreciation of information concerning research protocol. The subjects in the study were 30 inpatients and 30 outpatients with schizophrenia or schizoaffective disorder and, for comparison, 30 healthy subjects, all of whom received information about a simulated clinical drug trial. Using the MacArthur Competency Assessment Tool for Clinical Research (MacCAT-CR) as a gold standard, inter-rater reliability with intra-class correlation coefficient (ICC) was measured. The ICC for inter-rater reliability ranged from 0.987 to 0.994. The UBACC was found to be a useful and valid instrument for the screening of decision-making capacity before obtaining informed consent. We recommend that it be used not only for schizophrenia patients but also for various vulnerable groups including the elderly or cognitively impaired subjects.

본 논문은 기술거래 네트워크와 기술거래 관리의 개념을 제시하고 기술도입자가 도입하고자 하는 기술을 제공하는 최적의 기술제공자를 선택하는 방법론을 제시하는데 목적이 있다. 기술거래 네트워크는 기술제공자, 기술마케터, 기술도입자로 구성되며 기술거래 관리는 기술평가, 기술거래, 기술사업화의 단계로 이루어진다. 기술거래 네트워크에서 기술의 연관도와 기술도입비용의 최적화방법을 통해 기술도입자가 도입하고자 하는 기술을 제공하는 최적의 기술제공자를 선택하는 방법론을 제시하며 이 방법은 기술도입자가 기술을 선택하는데 있어서 유용하게 사용될 것으로 기대된다. 기술제공자 선택 방법론은 기술평가 프로세스와 기술제공자 선택 프로세스로 구성된다. 기술평가 프로세스에서는 기술성에 중점을 둔 새로운 개념의 기술평가방법을 개발하여 기술연관도를 정량적으로 산출하였고 기술제공자 선택 프로세스에서는 기술도입에 따른 제반비용을 정의한 후 기술연관도가 최대가 되고 기술도입비용이 최소가 되는 수리모형을 목표계획법을 이용하여 설계하였다. 기술도입자의 요구조건에 대한 성능을 효과적으로 분석하기 위하여 하위기술 별로 방향성을 부여하여 기술네트워크를 각각 구성하였고 이를 효과적으로 목표계획법에 반영하였다. 사례분석에서는 차기전차 기술제공자 선택 사례를 분석하였다. This study presents a concept of technology trade network and management, and proposes a procedural method for optimally selecting the technology transferor when a technology transferee needs to buy a specific technology. We develop a technology trade network where technology supplier, technology marketer, and technology transferee are informatively linked. And a technology trade management consists of three step of estimating technology, trading technology, and commercialization technology. Technology transferees could import the best appropriate technology which they want through these technology network method and cost optimization method. And we hope that these methodologies can be used in selecting new technology. A methodology can be classified into an estimating technology process and a choice of technology supplier process. In an estimating technology process, we calculate the technology similarity quantitatively through developing method of estimating technology which is focused on its technological characteristics. After defining the related cost of technology introduction, we suggest goal programming model to find a solution which can be acceptable both maximizing the technology similarity and minimizing the cost of technology. And suggested model is verified with a supplier selection problem of next generation tanks.

Background/Aims: Endoscopic mucosal resection (EMR) has been widely accepted as a curative treatment of early gastric cancer (EGC). The aim of this study was to determine the usefulness and limitations of EMR for treatment of EGC by analyzing our own experience. Methods: We retrospectively evaluated 51 EGC lesions (45 mucosal and 6 submucosal cancers) from 49 patients who had undergone EMR between Oct. 1997 and Aug. 2002 at Inha Universtiy Hospital. Results: Among 45 lesions of mucosal cancer, enbloc resection was performed in 13 lesions and piecemeal resection in 32 lesions. Complete resection rates of enbloc and piecemeal resection were 84.6% and 43.8%, respectively (p=0.012). Complete resection rate of the lesions smaller than 1 cm in size was 71.4%, 1 to 2 cm in size 52%, and greazter than 2 cm in size 37.5%. Complete resection rates of well, moderately, and poorly differentiated EGC were 59.4%, 71.4%, and 16.7%, respectively (p=0.048). Thirty-three patients underwent a follow-up endoscopy at I month after EMR and two were found to have residual cancers. One patient who had a piecemeal EMR showed cerical and abdominal lymph node metastasis 10 months after EMR. Conclusions: In selected patients with EGC, EMR can be a curative treatment modality. However, complete resection rate is low in large sized and poorly differentiated EGCs and when piecemeal resection is performed. (Korean J Gastroenterol 2003;42:453-460)
