The purpose of this study is to analyze the consumer preference disposition for the fruit soju for the constant growth of the fruit Soju industry. The conjoint analysis is used as a study method. It is a representative method to analyze consumers’ utilities. It is a technique to predict consumers’ choices for goods by measuring their utilities for each trait of the goods instead of evaluating the product itself. The partial value and the importance of main traits of fruit Soju consumers felt are apprehended through this conjoint analysis, and the market segmentation is conducted based on those values. Results show that consumers prefer a higher sugar fruit Soju with the current alcohol degree. Also, consumers are shown to prefer the soju contained in a glass bottle without carbonic acid as the current one. Furthermore, as a result of market segmentation, it is revealed both men and women prefer a higher sugar content, and women prefer a lower alcohol degree than men.

( Jiae Park ),( Jong Hun Kim ),( Young Kyung Yoon ),( Jang Wook Sohn ),( Min Ja Kim ) 대한내과학회 2016 대한내과학회 추계학술대회 Vol.2016 No.1
Purpose: Myositis as an extraintestinal complication of Campylobacter bacteremia is rarely reported. Here, we present a rare case of myositis due to C. fetus bacteremia.?Summary: A 57-year-old man with a history of diabetes mellitus, chronic kidney disease, and liver cirrhosis presented with a 4-day history of fever, malaise, and pain of right thigh. Initial vital signs were BT 39.3℃, BP 90/60mmHg, HR 102/min, and RR 20/min. On physical examination, erythematous tender swollen right thigh without open wounds was noted. The lab results showed WBC 45200/uL and CRP 150.61mg/L. Two sets of blood cultures were obtained on admission and empiric antibiotic therapy of cefotaxime was started. Despite of empiric antibiotic therapy, his right thigh pain persisted with the report of isolation of gram negative bacilli from admission blood culture. Thus, antibiotic therapy was changed to meropenem. MRI performed on the 3rd hospital day showed diffuse swelling and edematous changes in the right adductor muscle compartment without abscess, consistent with myositis. Gram negative bacilli seen from admission blood cultures were later identified as C. coli by the VITEK2 system. Given infrequent association between bacteremia and C. coli, 16S ribosomal RNA gene sequencing test was performed, which confirmed the identification of C. fetus. Further antibiotic susceptibility testing by E-test method was done, which demonstrated susceptibility to meropenem and ampicillin. Meropenem treatment was continued based on the antibiotic susceptibility results and disease severity. He responded well to meropenem treatment with clearance of bacteremia and resolution of right thigh pain as well as normalization of CRP. Repeat MRI test on the 32nd hospital day showed significant improvement of myositis. He was discharged in stable condition to continue oral ampicillin/sulbactam antibiotic treatment for additional one month, which resulted in complete resolution of infection.?Conclusions: This is the first documented case of myositis due to C. fetus bacteremia. Particular attention is needed for the patient with underlying medical condition (s) affecting the immunity for detection of rare complication of C. fetus bacteremia.

Purpose: The aim of our study is to assess short-term and long-term outcomes after laparoscopic radical rectal cancer resection in octogenarians compared with those in patients 60 years old or younger. Methods: Using a prospectively collected database of laparoscopic colorectal resections by a single surgeon from March 2001 to December 2012, we retrospectively reviewed 49 octogenarian rectal cancer patients and 63 younger counterparts. Results: The American Society of Anesthesiologists (ASA) score (P<0.001), history of previous abdominal surgery (P=0.019), preoperative prevalence of other malignancy (P=0.001), perioperative transfusion (P=0.032), and cardiorespiratory comorbidities (P<0.001) were significantly higher in octogenarians. No difference existed between two groups in terms of preoperative chemoradiation rate, surgical procedures, distal and radial resection margin, harvested lymph node number, and tumor node metastasis (TNM) staging. The rates of at least one complication (P=0.019), postoperative ileus (P=0.006) and cardiopulmonary complication (P=0.021) were higher in octogenarians, but rates of leakage and reoperation were not high. During median follow-up of 53 months, one pelvic recurrence developed in octogenarians. The overall 5-year survival rate was 63.9% in octogenarians and 93.7% in younger patients (P<0.001). Two-year disease free survival rate for pathologic stage III in octogenarians was 51.0%, much lower (P=0.008), but not so for stage 0-II than in younger patients. Conclusion: Octogenarian rectal cancer patients have more preoperative comorbidities and the benefit of laparoscopic rectal resection was still limited for reducing cardiopulmonary complication. More sophisticated preoperative assessment should be needed to find out very frail patients and less invasive alternative treatment should be taken into consideration for them.

Jiae Park(박지애),Youngho Lee(이영호),Gigyoung Park(박기경) 한국경영과학회 2009 한국경영과학회 학술대회논문집 Vol.2009 No.10
In this paper, we explore the cloud computing system that provides new business opportunities in IT industry. We clarify cloud computing environment and analyze key drivers of cloud service market. Motivated by the distribution process of cloud services, we design a set of cloud service models that pave the way for firm to identify profitable business cases. In addition, we propose revenue model for cloud service models according to services transaction system. Furthermore, we develop a modeling framework for selecting a suitable business model.

Background: Cytomegalovirus (CMV) and Clostridium difficile (CDIFF) co-infection in enterocolitis is uncommon. We present a pooled analysis of the reported cases to evaluate the epidemiology and outcome of concomitant CMV and CDIFF enterocolitis.?Methods: Pubmed was searched for English-written articles published up to May 2016. Articles that reported cases of concomitant CMV and CDIFF enterocolitis were reviewed.?Results: A total of 20 cases were identified. Median age was 57 years and there were 11 males. Significant underlying immunosuppressed conditions were noted in 8 patients (8/20, 40%; receipt of solid organ transplantation (SOT) in 5 patients, hematologic malignancy in 2 patients, advanced AIDS in 1 patient). No significant underlying medical condition was noted in 5 patients. There were 3 patients who had prior history of CDIFF infection (3/20, 15%). The majority of patients had recent use of antibiotics (15/20, 75%). Of note, median age for 5 patients who had no significant underlying medical conditions was 78 years. All patients had diarrhea with manifestation of bloody diarrhea in 11 patients (11/20, 55%). Diagnosis of CMV enterocolitis was made on the basis of positive biopsy result (20/20, 100%). CDIFF infection was diagnosed on positive toxin (16 patients), positive culture (3 patients), and morphology of pseudomembranous colitis (1 patient). Most of the patients (18/20, 90%) were treated for both CMV and CDIFF infection, except for 2 patients (one patient who was treated only for CDIFF infection and the other patient without available CDIFF treatment data). Anti-CMV therapy included ganciclovir, valganciclovir, and foscarnet. CDIFF treatment included metronidazole, vancomycin, and 1 case of fecal transplantation. Relapse of CDIFF infection was noted in 1 patient. There were 4 patients who underwent bowel resection surgery for treatment. Death (3/20, 15%) was noted in 2 SOT recipients and 1 elderly patient (83 years) without underlying medical condition.?Conclusions: CMV and CDIFF co-infection in enterocolitis is rare but has been increasingly noted for significant risks of morbidity and mortality, particularly for immunosuppressed patients and elderly patients.

Objectives: This study aimed to assess the scale and transmission patterns of coronavirus disease 2019 (COVID-19) in a religious village community in South Korea, to determine the risk factors of transmission, and to evaluate vaccine effectiveness.Methods: An epidemiological survey was conducted, and data were collected and analyzed from 602 villagers in the religious village community. Multivariate logistic regression analysis was used to identify the risk factors for COVID-19 transmission and to evaluate vaccine effectiveness.Results: The outbreak attack rate was 72.1% (434/602). The attack rate was high among women in their 60s, the unemployed, residents living near religious facility (<500 m), and the unvaccinated. Age, the distance between religious facility and residences, and the absence of vaccination were identified as risk factors for transmission. Vaccine effectiveness was 49.0%, and the highest effectiveness was seen in the age group of 59 years or younger (65.8%).Conclusion: This village community was isolated, with little communication with the outside world. However, the frequency of close contact between residents was relatively high, contributing to the spread of COVID-19 in the village even with relatively short exposure. Vaccination rates in the village community were also lower than those in the general public. Public health authorities should consider the potential impact of cultural factors, including religion, that could lead to the exponential spread of COVID-19 in closed village communities.
