[연구목적] 스마트기기의 보급에 힘입어 가까운 시일 내 가장 급변한 분야 중 하나는 금융 분야일 것이다. 전자 금융 분야에 있어서 가장 괄목할 만한 현상은 ‘스마트폰’으로 대변되는 모바일 장치를 활용한 새로운 전자 지급 수단의 출현을 들 수 있다. 하지만, 해외 선진국에 비해 국내의 도입은 상대적으로 늦었기에 스마트페이의 기능과 역할에 관한 연구는 부족한 실정이다. 이에 본 연구에서는 국내 보급된 ‘스마트페이’를 대상으로 실제 소비자들이 어떠한 요인과 기능을 중요시하는지에 대해 실증적으로 검증함과 동시에 향후 스마트페이 발전 방향성에 대해 제안함으로써 스마트페이 산업의 발전에 방향과 속도의 향상에 대한 기여를 하고자 하였다. [연구방법] 데이터는 선행연구에서 다룬 ‘스마트페이’ 기능을 중심으로 실제 소비자 면담을 통해 가장 많이 중복되는 23개의 기능을 추출하였으며 다시 이를 바탕으로 기능 및 의미가 중복되는 문항 3가지를 제외하여 최종적으로 선정된 20개 문항을 바탕으로 Kano 모델을 측정 하였다. 또한, Kano 모델이 지니는 단점을 보완하기 위해 추가로 고객 만족 계수와 PCSI 지수를 통해 통계적 단점을 보완하였다. [연구결과] 결론적으로 KANO 품질은 일원적 5가지 요인, 매력적 2가지 요인, 당연적 8가지 요인, 무관심 5가지 요인으로 분류되었으며 PCSI지수를 바탕으로한 서비스개선 우선순위는 사용가능 매장 수, 결제 속도, 보안 정보 인증 절차, 사용 가능 시간대, 결제내역 알림, 기기 호환성, 결제 난이도, 사용 가능 지역, 결제 금액 오류, 정보 보안성, 어플내 이벤트, 할인 및 혜택 쿠폰(오프라인), 기술적 문제, 보안 정보 등록 절차, 브랜드 인지도, 등록 가능 계좌 수, 부가혜택(앱), 스마트페이 UI, 설치 난이도, 사용시 배터리 소모율 순으로 나타났다. [연구의 시사점] 하지만 해당 수치는 얼마나 개선할 수 있는지에 대한 소비자 관점에서의 참고자료로써 실제 개선순위는 현재 보유 및 활용 가능 자산, 산업의 분위기 그리고 미래 운영 방향성에 따라 적용 되어야 할 것이다. 또한, 본 연구의 결과를 통해 스마트페이 분야 자체가 일반적인 서비스 시장보다 폐쇄적인 환경으로써 서비스 개선이 매우 어려운 산업 분야임을 확인할 수 있었고 서비스 개선의 효과가 단기간에 직접적으로 나타나기는 어려운 환경이기에 무리한 개선보다는 현재 가지고 있는 기능들의 안정적인 강화가 적합할 것이라는 점을 시사한다. [Purpose] With the spread of smart devices, one of the most rapidly changing fields in the near future will be in the financial field. The most remarkable phenomenon in the field of electronic finance is the emergence of a new electronic payment method that utilizes mobile devices represented by ‘smartphones’. However, since domestic introduction is relatively late compared to overseas advanced countries, research on the function and role of smart pay is insufficient. Therefore, in this study, by empirically verifying what factors and functions are important to actual consumers for ‘smart pay’ distributed in Korea, and suggesting the future direction of smart pay development, the direction and speed of the development of the smart pay industry. It was intended to contribute to the improvement of. [Methodology] The 23 most important factors were extracted through consumer interviews. Here, the Kano model was finally measured based on 20 items, excluding 3 items with overlapping meanings. In addition, in order to compensate for the shortcomings of the Kano model, the statistical shortcomings were supplemented through the customer satisfaction coefficient and PCSI index. [Findings] Quality classification was conducted through the KANO model, and the effect of service improvement was finally quantified through PCSI and priorities were selected. [Implications] Through the results of this study, it was confirmed that the smart pay field is an industrial field that is very difficult to improve service as it is a closed environment than the general service market. Therefore, it is difficult to see the effect of service improvement in a short period of time, so it would be better to reinforce the current functions rather than an excessive improvement.

Dong-Seok Park¹, Ji-Hoon Kim¹ and Byung-Il Min, Soo-Myung Oh,³¹Department of Acupuncture and Moxibustion, College of Medicine, ²Department of Physiology, College of Medicine, And ³East-West Medical Research Institute, Kyung Hee University,Seoul, Korea. Analgesic Effect of Manual Acupuncture and Electroacupuncture combined with Twirling Method. Proceeding of International Symposium on East-West Medicine Seoul. 187-200, 1999.-Twirling the needle (TN) is one of several needing methods frequently used for acupuncture in the oriental medicine. The present study was conducted to see if TN enhanced the antinociceptive effect produced by plain-or electroacupuncture in the rat tail flick test. Rats (Sprague-Dawley, 200-300g)lightly anesthetized with thiopental sodium(40mg/kg, i.p.) were used in the tail-flick test. The basal reaction time for tail-flick was 2 sec. For "plain" acupuncture(PA), a needle was inserted for 20 min into a Chock-samni (ST36) acupuncture point which (is located at the anterior tibial muscle and about 10mm below the knee joint). For electroacupuncture(EA), train-pulses(3 Hz,0.3-ms pulse width, 0.2-0.3mA) were applied to the inserted needle for the period of insertion. For combining TN with either PA or EA, TN was performed during the each acupuncture period. Two methods for TN were used; twirling 3 times for 1 second persisted for 1 min in every 5 mins(long-duration and long-interval;LDLI) and twirling 3 times for 1 second persisted for 10 sec in every 1 min(short-duration and short-interval;SDSI). PA and EA produced an increase in tail flick latency (TFL); peak increases were 21.3±5.1% and 42.1±17.3% of the pre-acupunture control, respectively, and occurred immediately after cessation of 20min-acupuncture. Performing TN combined with PA increased TFL more than PA itself by showing a greater peak increase in TFL when performed with a SDSI-TN than with a LDLI-TN(60.6±12.5% and 42.7±22.7% of the pre-acupuncture control, respectively). Performing TN combined with EA also increased TFL more than EA itself and a greater peak increase in TFL was observed with a SDSI-TN as compared to a LDLI-TN(77.5±13.8% and 67.3±14.0% of the pre-acupuncture control, respectively). These results indicate that TN enhances both PA-and EA-produced antinociception where an greater enhanced antinociception than a LDLI-TN. It is suggested that performing a SDSI-TN combined with EA seems to be one of the most effective ways to produce analgesia.

Epidural or intrathecal morphine injection is a useful method for management of postoperative pain and cancer pain. But the effect of intrathecal morphine is ten to twenty times more potent than epidural morphine. So inadvertent intrathecal injection of morphine during epidural injection can induce serious side effect. The authors report a patient who experienced respiratory arrest and loss of consciousness due to inadvertent intrathecal injection of high dose morphine during epidural injection for management of cancer pain. The patient was treated with intravenous bolus and infusion of naloxone for 8 hours and assisted ventilation with Ambu and she was recovered completely without any sequela.

Thoracic surgery may be greatly facilitated by causing selective atelectasis of the lung being operated on (one-lung ventilation anesthesia). But the tube used for one-lung ventilation is greater outer diameter than conventional endotracheal tube when compare to each other with same inner diameter, so in some young children it is impossible to one-lung ventilation using double lumen tube or bronchial blocker tube because of narrow vocal cord. We performed one lung ventilation anesthesia using conventional endotracheal tube and Fogarty catheter as a bronchial blocker in 11-year old women who received lung biopsy surgery and left lower lobectomy.

전치부 개교를 동반한 골격성 Ⅲ급 부정교합 환자의 악교정 수술 후 교합평면의 변화와 안정성에 관한 연구

신수정,황병남,이정근,이승훈 대한치과교정학회 1999 대한치과교정학회지 Vol.29 No.1

악골의 골격적 부조화를 가진 환자의 교정치료는 악교정 수술을 필요로 하고, 악교정 수술에 의해 교합평면각은 변화된다. 특히 전치부 개교를 동반한 III급 부정교합 환자에서 치아안면 기형을 치료하기 위한 교합평면각의 변화에 대하여 많은 논란이 있어 왔다. 교합평면각을 증가시키는 하악골의 시계 방향 회전(clockwise rotation)은 전치부 개교에 대한 적절한 치료법으로 추천되어 왔고 하악골의 반시계 방향의 회전(counterclockwise rotation)은 하악지 고경을 증가시키는 방향으로 하악골을 회전시킨다는 개념으로 인해 재발(relapse)을 유발하는 불안정한 수술 방법으로 인식되어 왔다. 본 연구는 전치부 개교를 동반한 골격성 Ⅲ급 부정교합 환자에서 교합평면의 반시계 방향회전을 동반한 하악지시상분할 골절단술 시행 후 교합평면각의 변화와 술후 안정성과의 관계를 평가하고자 하였다. 하악지 시상분할 골절단술과 rigid fixation으로 치료받은 환자 25명(평균연령 20.6세)을 대상으로 하여 수술 작전(T1), 술후 2주내(T2), 그리고 술후 6개월 이후(T3)에 촬영한 측모 두부계측 방사선 사진을 통계분석한 결과 (Paired t-test, Pearson correlation analysis), 다음의 결론을 얻었다. 1. 악교정 수술 후 (T2) 하악평면각은 2.9° 감소하였고 SN평면에 대한 하악 교합평면의 각도는 2.7°감소하였다. 술후 6개월경과 후 (T3)후안면 고경의 감소로 인해(P<0.01) 하악 평면각은 1.0° 증가하였으나 하악 교합평면의 경사도는 변화되지 않았다. 2. 악교정 수술 후 시간 경과(T3)에 의해 발생한 수평적 개발은 하악골의 전방 이동량이 B점에서 1.6mm로 수술시 전체 후방 이동량의 약 22%였다. 전안면 고경에서는 수직적 재발이 발생하지 않았으나, 후안면 고경은 감소하였다(P<0.01). 3. 수평적 재발과 상관관계를 보이는 항목은 하악평면각 이었고(P<0.01) 수술 6개월경과 후 후안면 고경의 감소와 상관관계가 있는 요소로는 수술시 하악골의 후방 이동량(P<0.01), 하악지 고경의 증가량(P<0.01), 그리고 하악평면각의 감소량(P<0.01) 등이 있었다. 4. 수술시 하악 교합평면 경사도의 변화량과 술후 재발과는 상관관계가 없었다. The purpose of this study is to investigate the stability of counterclockwise rotation of mandible by sagittal split ramus osteotomy to correct the skeletal Class Ⅲ malocclusion with anterior open bite. Twenty five skeletal Class Ⅲ open bite patients(mean age 20.6 years) who were treated by the sagittal split ramus osteotomies with rigid fixation were examined in this study. Cephalometric radiographs were taken for each patients preoperative (T1), early postoperative(T2), and late postoperative period(T3). Mean postoperative period was 8.0 months. Cephalometric analysis was done and data from T1, T2, T3 were analyzed statistically by Paired t-test and Pearson correlation analysis. The following results were obtained. 1. Mandibular plane angle decreased 2.9° and mandibular occlusal plane angle related to SNplane decreased 2.7° after orthognathic surgery(T2). At 6 months after orthognathic surgery(T3), mandibular plane angle increased 1.0°, but mandibular occlusal plane angle did not changed. 2. The amount of horizontal relapse long time after orthognathic surgery(T3) was 1.6mm at B point and it was 22% of the total posterior movements. There was no vertical relapse in the anterior facial height. 3. The related factor with horizontal relapse at late postoperative period was mandibular plane angle(p<0.01). The related factors with decreasing posterior facial height were amount of mandibular setback(p<0.01), increasing of mandibular ramus height(p<0.01), and decrease of the mandibular plane angle during operation(p<0.01). 4. There was no relationship between the amount of changes in mandibular occlusal plan angle during operation and the amount of relapse after surgery.

The primary intent of this study to introduce basic mathematical fire modeling. The approach is through the development of a simple mathematical model that will provide on engineering approximation of the time-varying condition created by a fire in an enclosure that may be subject to hot-layer venting. The hot-layer, as it is commonly referred to in fire modeling, is the collection of hot gases generated by a fire that forms below the ceiling due to its buoyancy over the ambient temperature air in the compartment. In the model, venting due to buoyancy forces is considered, with vent flows associated with momentum and forced ventilation are not. Also, venting through opening in vertical planes(walls) is considered, and openings in horizontal planes(floor and celling)are not. Early work revealed two general approaches for a solution. First, there was the opportunity to simplity an existing, but complex model, such as the Harvard Code, FIRST, or FAST, or FAST. A second option would be to take existing simple model such as ASET-B, and upgrade it is meet the requirements of model and documentation sought. However, during the modification of ASET-B, it became apparent that it could be simplified move. As a result, the model developed here is not simply a modification of ASET-B, but a completely new model. however, the ASET-B model did have an important role in the development of the there model. Initial motivation for the simplicity and structure of the model was so that it could be used as a tool in the investigation and reconstruction of fires. Modified FIRM(Fire Investigation and Reconstruction model)is certainly not limited to those uses.

방사선치료에 사용되는 대표적인 부정형조사면 다섯가지에 대한 각 관심점에서의 선량계산을 위하여 새로 고안한 도표를 사용하여 Co-60감마선에 대한 부정형조사면의 조직공중선량비(TAR)를 계산하였다. 도표를 이용한 계산과 기존의 계산법인 컴퓨터계산법 및 근사법으로 구한 TAR를 측정에 의한 TAR에 비교하여 다음과 같은 결과를 얻었다. 관심점이 방사선속의 중심축상에 있을 때 부정형조사면에서 이들 방법으로 구한 TAR의 대부분은 오차가 1% 이내에서 잘 일치되어 있으며, 축으로부터 벗어난 경우에는 최대 오차가 각각 2.4%,2.3%, 및 8.8% 이었다. 이들 결과로부터 새로 고안한 도표를 이용한 계산법의 정확성을 확인하였다. In order to calculate the dose on each interest point in five types of irregularly shaped fields used commonly in radiotherapy, the tissue-air ratios (TAR) in these fields for Co-60 gamma radiation were calcnlated using the newly devised SAR-chart. The TARS calculated from newly method of using the SAR-chart. computer method and approximation method at the interest point were compared to the TARs obtained from measurement. The result are as follows: In case of the interest points on central axis the calculated TARs in irregularly shaped fields by the above metioned methods were well agreed within the error of 1%, whereas for the interest points on off-axis the calculated TARs were resulted in the maximum errors of 2.4%, 2.3% and 8.8% respectively. From these results, the accuracy of calculation method of using the SAR-chart was comfirmed.

냉간압연된 Ni₃Al 박판재의 내산화 특성 개선을 위한 NiAl-Ti-Y 코팅의 증착

Since the intermetallic compound Ni_(3)Al has attractive high-temperature properties, Ni_(3)Al thin foils could be used as lightweight, high-temperature structural materials. The floating zone (FZ) method makes it possible to fabricate the thin foils with smooth and crack-free surface by cold rolling up to 96% without any intermediate annealing steps. For the practical application of Ni_(3)Al foils, the other properties such as oxidation resistance, wear resistance and friction resistance should be considered. The 3-NiAl, which is one of the important intermetallic compound in Ni-Al systems together with γ-Ni_(3)Al, have been used as coating materials of Ni-base superalloys because of its excellent oxidation resistance. In this study, the NiAl-based coating was intended to deposit on the Ni_(3)Al foils through RF magnetron sputtering. The binary Ni-50Al coating, however, was not able to form the stable α-Al_(2)O_(3) oxide. Moreover, the rapid Al diffusion between coating layer and substrate was occurred. On the contrary, it was found that the Ni-47Al-3Ti-0.1Y coating showed superior oxidation resistance due to stable α-Al_(2)O_(3) formation and good retardation of Al diffusion from coating layer.
