  • 초고속 패킷 스위칭 네트워크에서 QoS 보장을 위한 여러 가지 방안 중 우선순위에 의한 패킷처리 방식이 선호되고 있다. 초고속 패킷 스위치에서 우선순위에 따르는 효율적인 패킷 처리는 서비스 성능 향상의 관건이다. 따라서 초고속 네트워크 내의 핵심인 패킷 스위치에서의 효율적인 우선순위 서비스 알고리즘의 개발은 중요하다. 본 논문에서는 효율적인 패킷 스위치 성능 향상 방안으로 큐에 대기하는 패킷의 개수에 따라 서비스시간을 가변적으로 할당할 수 있는 W-iSLIP 스케줄링 알고리즘을 제안하고, 시뮬레이션하여 기존의 알고리즘과 비교 분석하였다. 우선순위에 따른 서비스와 전체 지연시간을 분석한 결과, 전체 지연시간에 있어서는 2.6%, 우선순위 서비스에 있어서는 34.6%의 성능향상이 있는 것으로 분석되었다.

  • Drug identification service and other drug-related query service are becoming increasingly important in hospital pharmacy. The goal of this research was to investigate current situation of the service in hospital pharmacy, which recently implemented the services as part of provision of advanced hospital pharmacy service in order to assure national health improvement. We investigated the report performed from November 2006 through April 2007 in a university hospital located in Daegu, Korea. Number of drug identification service performed was 81 cases during the first three months period (period I), but it increased to 222 cases during the second three months period (period II), which suggested that the service was welcomed by medical staff in the hospital. Time to process each case was about 30 minutes in the period I while it was only 16 minutes in the period II. Proportion of the unidentifiable cases remained at about 25% during the entire period, which suggests that the system for the identification task appears to have some limitations such as unsatisfactory support from the Korea Pharmaceutical Association, laws, and regulations. A vast majority of drug-related queries were mostly from physicians (60.5%) followed by nurses and pharmacists. Time to process each drug-related query was 10.6 minutes in the period I while it was 6.9 minutes in the period II. Queries answered immediately were about 70% of all queries in the period I, but increased to about 85% in the period II.

  • The purpose of this study was to investigate service quality of department stores located in Daegu and to examine the effects of service quality on customer satisfaction and store patronage. Data(N=285) were analyzed, using factor analysis, 1-test, ANOVA and regression analysis. The results suggest that service quality was divided into 3 dimensions (reliability, tangibles, empathy) and that service quality enhanced customer satisfaction and store patronage. Specifically, tangibles had a positive effect on customer satisfaction, and reliability had a positive effect on store patronage. Also, personal characteristics were related to service quality, customer satisfaction and store patronage. For instance, male customers evaluated tangibles of service quality more positively than female customers. The married evaluated service quality, customer satisfaction and store patronage more positively than the single. While people aged above 36 yews evaluated reliability and empathy of service quality more positively than people aged below 35 years, people in their 20s evaluated tangibles more positively than people in their 30s. People in a higher income bracket (i. e., \301,000,000- \400,000,000) evaluated reliability and empathy of service quality and store patronage most positively, while people in a lower bracket (i. e., below \200,000,000) evaluated most negatively.

  • This case describes outbreaks of acute aspergillosis in a red-crowned crane. A six-month-old, male, crane had showed clinical signs (i.e. anorexia, performance loss, ruffled feathers and drooped wings and open mouth breathing, etc.) before death. In necropsy examination, spherical to oval nodules disseminated from the respiratory tract to other organs. Those nodules were formed predominantly in air sacs, lung, peritoneum, serosa of esophagus and trachea. The nodules varied in size from 1 mm to over 1cm and the color was white to yellow. Microscopically, most of lung architecture were replaced by multiple foci which were characterized by well demarcated eosinophilic and karyorrhetic debris and surrounded by numerous Inflammatory cell. Most within necrotic center of the nodules, large numbers of fungal hyphae were present. Microbiology result indicated fungal growths on sabroud dextrose agar and bacterial growths on blood agar. Bacteria identified as E. rhusiopathiae using MALDI-TOF (microflex, BRUKER, USA) and fungi identified as A. fumigatus, A. terreus by sequencing the ITS1 and ITS4 regions. To confirm the route of infection, we checked the existence of the same pathogens in cohabitant (i.e. mother crane). The young age and weakened immunity (i.e. bacterial infection, etc.) causes fatal aspergillosis in birds.

  • 기존 인터넷 웹 사이트에서는 개인 식별 도구로 주민등록번호를 사용해 왔다. 그러나 인터넷에서의 주민 등록번호 사용은 개인정보 유출 위험을 증가시키는 주 요인이 되고 있다. 현재 정부에서는 인터넷에서의 주민등록번호 수집과 개인정보 유출 최소화를 위해 i-PIN 서비스를 권장하고 있다. i-PIN의 원래 사용 목적은 인터넷 웹 사이트에서 주민등록번호를 사용하지 않고 i-PIN 13자리 가상번호로 개인을 식별하여 사용된다. 최근에는 i-PIN을 인증서 형태로 사용하는 사례가 늘고 있다. 본 연구에서는 i-PIN을 인증서 형태로 사용하는 소프트웨어 서비스 방법론과 기존 i-PIN 서비스와는 다른 형태의 i-PIN 본인인증서비스 적용 사례를 알아보고자 한다.

  • The purpose of this study was to measure customers' perception of the service quality of Korean restaurants and then compare differences in perceived service quality according to customer nationality. Self-administered questionnaires were completed by 2812 subjects, and data were analyzed by frequency, chi-square, t-test, one-way ANOVA, factor, reliability, cluster, and discriminant analysis. Results of the study were as follows. The factor analysis of perceived service quality produced four factors, employee service (5 variables), menu quality (4 variables), price & value (4 variables), and physical environment (4 variables). Cronbach's alpha values for reliability were over 0.8 for all factors. Further, a significant difference was observed in service quality, which was perceived according to customer nationality. A higher mean value of perceived service quality was held by foreigners when compared to Koreans. Especially, the mean value of perceived service quality was significantly low for all items for Japanese compared to foreigners. Cluster analysis divided subjects into two groups based on attitude toward service quality of Korean restaurants: an unfavorable group and favorable group. These two groups differed from each other in general characteristics as well. Limitations and future research directions are also discussed.

  • 예비교사에게 요구되는 학생 평가 전문성은 평가방법을 선택하고, 평가도구를 개발하고, 평가를 실시하여 채점하고, 평가 결과를 분석하고 해석하고 활용하는 일련의 과정을 경험하고, 그것을 반성할 때 신장될 수 있다. 본 연구는 예비교사들을 대상으로 평가 과정 전반을 경험하는 실습과 학습 일지를 통한 반성을 경험하게 하여 이들의 평가 전문성 신장이 어떠한지 알아보았다. 학습일지는 예비교사의 평가 관련 지식, 학생과 교사의 이중적 입장, 평가 실행의 영역에서 분석되었고, 그 결과 이 세 가지 영역은 상호작용하며 예비교사의 전문성을 신장시키는 데 기여했으며, 각각의 영역은 예비교사의 평가 전문성을 구성하는 요소가 되었다. 그리고 예비교사의 평가 전문성 신장을 양적으로 확인한 결과, 사전 검사에 비해 사후 검사의 평균 점수가 신장되었다.

  • KakaoTalk has become a reputed mobile social network and an inseparable part of people's lives by leading the mobile industry in South Korea. However, there is a lack of studies in academia regarding perception of the consumers and assessment toward the mobile marketing and services by KakaoTalk. Based on the theoretical orientation of Elaboration Likelihood Model (ELM: Petty & Cacioppo, 1986) and electronic service quality (E-S-QUAL: Parasuraman, Zeithaml, & Malhotra, 2005), this study investigates the effects of information sources (Charles & Richard, 1988), and examines the consumer perception toward the service quality of KakaoTalk. A total of 209 responses were collected, using a self-administered survey in Seoul and Gyeonggi province, South Korea from March 2015 to June 2015. A seven-point Likert scale survey was developed to measure the information sources (i.e., argument quality, post popularity, and post attractiveness), electronic service quality (i.e., efficiency, fulfillment, privacy, and system availability), attitude (i.e., usefulness, preference, and overall attitude), and behavioral intention (i.e., like intention, share intention, and purchase intention). This study reveals a consensus that an online environment is different from the traditional retail context in terms of information source and service quality. Specifically, the results indicate that argument quality greatly impacts the attitudes of the individuals and their behavioral intention toward mobile shopping via social media channel. The most powerful factor among E-S-QUAL is "efficiency." This dimension of service quality influences the customer perception of usefulness and preference as well as share and like intention toward mobile shopping on KakaoTalk.
