김유일,Soo Yeong Moon,Dong Un Song,Ki Hyun Lee,Jae Wook Song,Young Eun Kwon 대한마취통증의학회 2013 Korean Journal of Anesthesiology Vol.64 No.2

Background: Postoperative nausea and vomiting (PONV) are common complications after anesthesia and surgery. This study was designed to compare the effects of palonosetron and ondansetron in preventing PONV in high-risk patients receiving intravenous opioid-based patient-controlled analgesia (IV-PCA) after gynecological laparoscopic surgery. Methods: One hundred non-smoking female patients scheduled for gynecological laparoscopic surgery were randomly assigned into the palonosetron group (n = 50) or the ondansetron group (n = 50). Palonosetron 0.075 mg was injected as a bolus in the palonosetron group. Ondansetron 8 mg was injected as a bolus and 16 mg was added to the IV-PCA in the ondansetron group. The incidences of nausea, vomiting and side effects was recorded at 2 h, 24 h, 48 h and 72 h, postoperatively. Results: There were no significant differences between the groups in the incidence of PONV during 72 h after operation. However, the incidence of vomiting was lower in the palonosetron group than in the ondansetron group (18% vs. 4%, P = 0.025). No differences were observed in use of antiemetics and the side effects between the groups. Conclusions: The effects of palonosetron and ondansetron in preventing PONV were similar in high-risk patients undergoing gynecological laparoscopic surgery and receiving opioid-based IV-PCA.

Background: Insertion of a ProSeal(TM) laryngeal mask airway (PLMA(TM)) by experienced users was more successful with using a catheter-guided (CG) technique than a digital technique. The purpose of this study is to assess the efficacy of the CG insertion technique for a PLMA(TM) by inexperienced personnel. Methods: Forty patients aged 18-65 yr and who were undergoing general anesthesia were randomly allocated to the index finger (IF) or CG insertion techniques for PLMA(TM) insertion. The IF technique was performed with the routine insertion technique. The CG technique was performed using a catheter inserted PLMA(TM), which was primed into the drain tube of the PLMA(TM) with using a soft flexible catheter. Successful insertion was primarily judged by the clinical function of the airway. The number of insertion attempts and the insertion time were recorded. Postoperative airway morbidity (sore throat, dysphonia, dysphagia) was assessed at 24 hr postoperatively. Results: The success rate was similar between the groups (IF, 18/20; CG, 15/20). The successful insertion time (the time to provide an effective airway) was similar between the groups but the insertion time at the first attempt was shorter for the IF technique (IF, 21.6±5.3 s; CG, 27.4±10.3 s). There were no differences between the groups for the postoperative airway morbidity. Conclusions: This study suggests that the CG insertion technique is not a useful alternative technique for inexperienced personnel. (Korean J Anesthesiol 2009; 56: 634~8)

A prestudy on expendable turbine engine for high-speed vehicle was conducted. After two possible mission profiles were established to decide the engine requirements, design point analysis was performed with the values of design parameter which were obtained from similar class engines, references, etc. The results showed that specific net thrust and specific fuel consumption with turbine inlet temperature of 3,600 R are 2,599.4 ft/s and 1.483 lb/(lb*h) respectively at the flight condition of sea level, Mach 1.2. It was also found that major design parameters for determining maximum net thrust were turbine inlet temperature for low supersonic and transonic flight speed and compressor exit temperature for high supersonic flight speed from the results of performance analysis on the two possible mission profiles. In addition, simple turbojet engine with an axial compressor, a straight annular combustor, an one stage axial turbine and a fixed throat area converge-diverge exhaust nozzle was proposed as the configuration of simple low cost lightweight turbine engine.

The engine ground and altitude tests were carried out to investigate the effect of jet fuel alteration on the performance of a small turbojet engine. JP-S was supplied 8% higher than JP-8 by fuel metering system at the same command. The employment of JP-S showed the similar starting characteristic to that of JP-8, however, difference in the ignition time and acceleration rate of engine speed due to the difference of fuel flow rate by fuel metering system was observed. In spite of jet fuel alteration, the test results yield the similar steady-state engine performance in net thrust, air flow, exhaust gas temperature, etc. On the other hand, the fuel consumption of JP-S increased by 5 % compared with that of JP-8. In point of specific fuel consumption (SFC), SFC of JP-S was approximately 1.1~2.6 %, 5 % higher than that of JP-8 in ground and altitude tests respectively at the same thrust.

The purposes of this study were to explore the differences in expectations and perceptions of job-seekers and employees from the perspectives of compensation, skill, and information and to discuss the potential solution to mitigate job mismatch in Kwangyang Bay area. Specifically, first, expectation level and the gap between expectation level and present level were analyzed for job-seekers and employees and second, the potential solution for mitigating job mismatch were suggested through comparing the mismatch level by items. For these purposes, total of 113 job seekers and 80 employees from small and medium size firms were included in the analysis. Mink’s “The Locus for Focus Model” was used for the analysis. This graph has expectation level on the x-axis and the gap between expectation level and present level on the y-axis. The differences in paired coordinates illustrate the respondents’ priorities. The main findings were as follows: 1) wage level, work environment, employee-welfare, work hours, firm future vision, and individual development showed higher mismatch level. 2) in the case of skill mismatch, certificates, IT ability, work-related experience, job interest, and communication ability perceived by job-seekers were lower than employees’ required level for work. 3) information mismatch revealed higher level in wage level, work environment, firm future vision, and individual development. Consequently, rather than blindly encouraging young job seekers to settle for less and limit their search to small, mid-sized employers, it appears that the efforts to reduce job mismatch level by priority needs should be proceeded and also, small business employers should diversify recruit target beyond the youth. 이 연구는 중소기업과 구직자간의 생각의 접점을 찾을 수 있는 정책적 대안을 모색하고자 광양 산업단지 중소기업 재직자와 인근 지역 구직자들을 대상으로 보상, 숙련, 정보의 측면에서 미스매치 수준을 논의하였다. 구체적으로 첫째, 구직자와 재직자를 대상으로 기대 수준 및 현재 수준의 차이를 분석하고, 둘째, 항목별 불일치 수준을 비교함으로써 미스매치 개선방안을 도출하였다. 광양을 포함한 인근 지역의 구직자와 중소기업 재직자를 유의표집하여 최종 113명의 구직자와 80명의 재직자가 분석에 포함되었다. 일자리 미스매치 영역에 따른 정책적 시사점을 제시하기 위해서 Mink의 “The Locus for Focus Model”을 활용하였다. 연구결과는 다음과 같다. 첫째, 구직자 기대수준이 높은 급여수준, 근무환경, 직원복지수준, 근로시간, 기업의 미래비전, 개인발전가능성에서 기대수준과 현재 수준의 차이가 큰 영역으로 나타나 미스매치의 문제가 심각함을 알 수 있었다. 둘째, 숙련의 미스매치에 있어서는 자격증, 정보기술 활용능력, 업무 관련 경험, 직업에 대한 흥미, 커뮤니케이션 능력에 대해 높은 수준의 재직자 기대수준에 비해 구직자가 현재 갖추고 있는 정도가 충분하지 않은 것으로 나타났다. 셋째, 정보의 미스매치에 있어서는 구직자 기대수준이 높은 급여수준, 근무환경, 기업의 미래비전, 개인발전가능성 관련 정보에 대한 적극적인 공개가 중요한 것으로 나타났다. 본 연구는 신규 구직자들과 기존 근로자들의 노동시장, 근로조건에 대한 인식의 차이가 크다는 것을 확인할 수 있었다. 이에 따라 무조건 청년들에게 눈높이를 낮춰 중소기업으로 유도하기 보다는 미스매치 수준을 완화하고자 하는 노력과 함께 중소기업들이 채용 대상을 다양하게 찾는 것이 중요할 것으로 생각한다.

응용프로그램 로더와 동적 링커는 응용프로그램이 실제로 실행되기까지의 준비 과정을 담당하는 프로그램들이다. 최근의 WIPI 표준은 휴대폰에 새로운 응용프로그램을 전송 받아 수행할 수 있는 환경을 제안하고 있지만, 휴대폰과 같은 제한된 이동단말기에서 사용할 만한 로더와 동적 링커는 공개되어 있지 않다. 본 논문에서는 이동단말기 환경에서 응용프로그램 로더와 동적 링커를 개발하는 과정을 설명한다. 개발에 참가한 연구진의 경험을 소개함으로써 이후의 비슷한 환경에서 로더와 링커를 개발하려는 연구자들에게 중요한 참고자료로 활용될 수 있을 것이다.

온라인 과학기술정보자원의 분류체계에 대한 실천적 구성방안

김유일,최성배,구영덕,Kim, You-Eil,Choi, Sung-Bae,Koo, Young-Duk 한국과학기술정보연구원 과학기술정보센터 2006 Journal of Information Science Theory and Practice Vol.37 No.4

인터넷의 등장은 과학기술정보의 생산과 유통에 많은 변화를 초래하고 있다. 기존 과학기술정보들은 주로 문헌위주로 생산되었다. 그러나, 인터넷이 대중화되면서 온라인 과학기술정보들이 대량으로 생산되고 있으며, 그 활용이나 중요도 또한 과학기술분야의 문헌에 뒤지지 않고 있다. 온라인 과학기술정보의 양적 질적 성장으로 인해, 정보서비스기관들은 이들 정보들의 체계적인 관리와 효율적인 서비스를 고민하고 있으며, 다양한 정보관리방법을 모색하고 있다. 효율적인 정보 관리를 위한 방법 중의 하나인 분류체계는 주요한 이슈이며, 지금까지는 문헌정보 중심의 분류체계나 일반 웹사이트의 분류체계를 벤치마킹하여 온라인 과학기술정보를 위해 도입되는 경우가 많았다. 본고에서는 국가 차원의 표준분류를 이용하여, 온라인 과학기술정보를 위한 분류체계 구성방안을 실천적으로 제시하여 보았다. The advent of the internet has caused a number of changes in production and dissemination of science and technology information(STI). STI was mainly produced in the form of publication before the advent of the internet. The popularization of the internet, however, has induced the mass production and distribution of STI through the internet. In consequence, the importance and usefulness of on-line STI have become on a level with those of published STI. The rapid growth of quantity and quality of on-line STI forces information service organizations try their best for improving the service satisfaction. In an effort to improve the satisfaction, researchers on information management examined the classification of information resources by exploring the counterparts of bibliography and/or web information service. We examined the national standard of the classification related to science and technology and proposed a practical scheme for the classification of on-line STI resources.

Congenital Peribronchial Myofibroblastic Tumor: A Case Study and Literature Review

김유일,조은윤,박하영,조준훈,한정호 대한병리학회 2013 Journal of Pathology and Translational Medicine Vol.47 No.2

Congenital peribronchial myofibroblastic tumor (CPMT) is a benign pulmonary spindle cell neoplasm of intrauterine and perinatal period, which is thought to arise from primitive peribronchial mesenchyme. We present a case detected incidentally in a one-month-old infant. The solid and partially necrotic tumor involved the right middle and lower lobes of the lung with extension to the diaphragm. Histologically, the tumor was composed of fasciculated monotonous spindle cells, proliferating peribronchiolar cartilage and round cells with rich vasculature, and high mitotic activity was identified in the round cell area. Immunohistochemical and electron microscopic studies showed that the spindle cells were myofibroblastic in phenotype. Although the tumor showed several malignant pathological features, recurrence was not observed in the two-year follow-up period, consistent with the benign clinical behavior of CPMT.
