Planning/planning stage Construction cost prediction is very important. In particular, flexible thinking is required to predict the construction cost by reflecting rapid market changes and current conditions. Therefore, in this study, we tried to consider the process for calculating the construction cost of an apartment house in a more accurate planning/planning stage. First, cases were collected based on the classification system by construction type. Second, the construction cost was predicted using the case-based reasoning technique. Third, the composition ratio by construction type of the most similar case was applied to the derived construction cost. Finally, the construction cost was predicted based on practical corrections reflecting the market and field conditions.
나는 결코 루터를 따르지 않는다 : 에라스무스의 “자유의지에 대하여”의 분석 (me numquam iurasse in verba Lutheri)
류성민 ( Ryu¸ Seong Min ) 아세아연합신학대학교 ACTS 신학연구소 2020 ACTS 신학저널 Vol.46 No.-
에라스무스는 15-16세기 최고의 인문주의자로서 교회의 갱신과 학문의 발전을 위해 노력하였다. 루터가 교회의 신학적 갱신을 주장하며 나타나자 사람들은 에라스무스가 루터의 뒤에 있는 것이 아닌가 의심하였다. 그래서 에라스무스는 가톨릭 진영과 개신교 진영으로부터 한 쪽에 서기를 강요받았다. 그는 루터를 따르지 않았지만, 그렇다고 루터를 이단으로 정죄하는 일에 참여하고 싶지 않았다. 루터를 정죄함으로 교회 갱신이 실패에 이를까 우려했기 때문이다. 그러나 그는 망설였지만, 결국 “자유의지에 대하여”라는 저술로 자신의 입장을 분명하게 공표할 수밖에 없었다. 이 저작의 서론에서 그는 자신이 자유의지 주제가 상당히 어려운 문제이기 때문에, 확실한 결론을 주장하는 것은 옳지 않다고 주장한다. 그와 달리 확실한 결론을 주장하는 루터가 성경해석의 유일한 권위자도 아님을 지적한다. 심지어 루터의 교리가 사람의 자유의지를 반대함으로 비윤리적이라고 주장한다. 이어 자료모음 부분에서 집회서 15장을 비롯한 자유의지를 찬성하는 신구약의 증거자료들을 소개하고, 반대하는 듯한 신구약의 구절들을 소개하고, 해설한다. 결론에서 에라스무스는 자유의지라는 난제에 하나님의 은혜와 사람의 자유의지의 신인협동적 모델을 제시한다. 이를 통해 사람에게 윤리적 책임성을 부여한다. 에라스무스는 이 저작을 통해 가톨릭에게 자신의 신학적 입장을 분명히 하는 신학적 목적과 함께, 루터의 교리가 사람의 윤리적 방종을 조장한다는 것을 지적함으로, 교회 갱신을 위한 자신의 입장을 변호하고 있다. Erasmus, as the foremost humanist of the 15th and 16th centuries, made efforts for the renewal of the church and the development of academics. As Luther emerged claiming theological renewal of the church, people suspected Erasmus was behind Luther. So, Erasmus was forced to stand on one side by the Catholic and Protestant camps. He didn’t follow Luther, but he did not want to take part in the process of convicting Luther as heresy. This is because he was worried that the church’s renewal would fail by convicting Luther. He hesitated. However, he had no choice but to make his position clear in “Of free will.” In the introduction of this work, he argues that it is not right to insist on a definite conclusion, because thesubject of free will is a very difficult problem. On the other hand, he points out that Luther, who insists on a clear conclusion, is not the only authority in the interpretation of the Bible. Futher, he argues that Luther’s doctrine is unethical by opposing a person’s free will. In the collection section, he introduces evidence of the New and the Old Testament in favor of free will, including Sirach 15. He also introduces and explains passages of the New and the Old Testament that seem to be against free will. The article concludes that Erasmus presents a synergistic model of God’s grace and man’s free will. This gives a person ethical responsibility. Through this work, Erasmus defends his position for church renewal and clarifies his theological position to the Catholic Church, while pointing out that Luther’s doctrines promote mankind’s ethical indulgence.
An Empirical Analysis on Long Tail Patterns with Online Daily Deals
Seongmin Jeon(전성민) 한국전자거래학회 2014 한국전자거래학회지 Vol.19 No.1
전자상거래 시장에서 롱테일 경제가 출현함에 따라 80/20 룰로 알려진 파레토 법칙의 일반적인 적용에 의문이 제기되고 있다. 이러한 제품 집중도의 변화는 인터넷 인프라 기반기술 위에 구현된 대량맞춤(mass customization)에서 기인한다고 예측된다. 본 연구는 그루폰과 유사한 소셜 커머스 웹사이트로부터 얻은 실거래 정보를 실증 분석하여 제품 및 고객 집중도를 분석하였다. 분석 결과, 이전 전자상거래 연구와 같이 소셜 커머스에서도 파레토 법칙과 다른 롱테일 패턴이 나타났다. 더욱이 email 또는 SMS를 통한 홍보가 판매 집중도 패턴에 영향을 미치는 것으로 파악되었다. email과 SMS를 통한 홍보는 모두 소셜 커머스 쿠폰 판매를 증가시킬 것이라는 예상과는 달리, SMS 홍보는 쿠폰 전반적으로 판매를 증가시키나, 소량판매 제품의 경우 email 홍보는 오히려 제품 판매를 감소시키는 결과를 보였다. The renowned Pareto rule of 80/20 has been challenged in the electronic marketplace with the emergence of long tail economy. Mass customization on top of the Internet infrastructure is expected to explain these changes of product concentration. In this paper, we empirically analyzed the micro-transactional data of a Groupon-like daily deal web site to identify the changes of product and customer concentration. The results show the long tail pattern aligned with the previous research on the e-commerce literature on the long tail. We find that the notification setting on email or SMS about daily deal influences the patterns of sales concentration. The information through email and SMS is expected to enable consumers to know about daily bargains and purchase the coupons eventually. However, the email notification for niche products results in the decreased sales while the SMS notification for overall product promotes overall products.

Objective: Minimally invasive surgery has become essential technology in field of gynecologic malignancies including cervical cancer. We reviewed our experience and evaluated the results of radical hysterectomy in patients with early stage cervical cancer. Methods: This retrospective study included patients with early stage cervical cancer (Ia1 ~ IIa2) who were treated with radical hysterectomy from January 2001 to April 2018. Patients were divided into two groups according to the approach of surgery: open laparotomy (ARH) or minimally invasive surgery (MIS, including conventional laparoscopy and robotic assisted laparoscopy, LRH and RRH). The type of hysterectomy included Piver type II and III hysterectomy. The survivals were compared using KaplanMeier curves. Differences in surgical outcomes between the two groups were also analyzed. Results: There were 178 patients totally: 59 in ARH, 58 in LRH, and 61 in RRH. Total number of surgeons in the period was 8, and the mean follow up period was 58.9 months. The patients demographics were not different between groups, including age, BMI, clinical stage, tumor marker level and histology of the tumor. The pathologic results for risk factors of recurrence were also similar, but the total number of lymph node yields were higher in ARH than MIS group. The 10-year cumulative recurrence was 6.3% in ARH and 9.1% in MIS which is not different in log-rank test (p=0.526). The 5-year overall survival was 96.2% in laparotomy and 95.3% in MIS, and also showed no difference between groups. Conclusion: The MIS is a safe and feasible option of radical hysterectomy in early stage cervical cancer. The clinical significance of the difference in LN yield should be further evaluated with long term follow up. The definite surgical skill and the efforts to reduce dissemination of tumor cells in pelvic cavity is necessary to maintain the quality and acceptable surgical outcomes of MIS.
Multiscale Implicit Functions for Unified Data Representation
( Seongmin Yun ),( Sanghun Park ) 한국인터넷정보학회 2011 KSII Transactions on Internet and Information Syst Vol.5 No.12
A variety of reconstruction methods has been developed to convert a set of scattered points generated from real models into explicit forms, such as polygonal meshes, parametric or implicit surfaces. In this paper, we present a method to construct multi-scale implicit surfaces from scattered points using multiscale kernels based on kernel and multi-resolution analysis theories. Our approach differs from other methods in that multi-scale reconstruction can be done without additional manipulation on input data, calculated functions support level of detail representation, and it can be naturally expanded for n-dimensional data. The method also works well with point-sets that are noisy or not uniformly distributed. We show features and performances of the proposed method via experimental results for various data sets.
