[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.

捻轉法이 竝行된 鍼刺戟 및 電鍼刺戟이 鎭痛效果에 미치는 影響

Park, Dong-Seok,Kim, Ji-Hoon,Min, Byung-Il,Oh, Soo-Myung 경희대학교 동서의학연구소 1999 INTERNATIONAL SYMPOSIUM ON EAST-WEST MEDICINE Vol.1999 No.1

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.

The Ni-rich β-NiAl alloys are considered as potential materials for high temperature shape memory alloys because of their higher thermoelastic martensite transformation temperature. But the transformation to Ni_5Al_3 phase occurring at 450∼550℃ during heating of NiAl martensite interrupts the reverse martensitic transformation, and causes the shape memory effect in NiAl martensite to disappear. In the present study, the phase transformation process in binary Ni-(33∼37 at.%)Al martensite was investigated by DTA, and it was found that the blocker of reversible martensitic transformation was not the β→Ni_5Al_3 transformation but the M→Ni_5Al_3 transformation occurring at 250∼300℃. Therefore, the transformation temperature of M→Ni_5Al_3 determined the critical temperature for operation of shape memory effects. In addition, for verifying the critical temperature, the phase transformation process was investigated for various ternary Ni-33Al-X alloys (X = Cu, Co, Fe, Mn, Cr, Ti, Si, Nb). As a result, Ti, Si and Nb were very effective to lower the A_s, temperature of Ni-33Al-X alloys, facilitating the shape memory effect in Ni-33Al-X alloys. Especially, Si and Nb additions were beneficial for increment of the transformation temperature of M→Ni_5Al_3, resulting in higher operating temperatures of NiAl-based shape memory alloys.

장수호,임성훈,김광원 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.5

니켈-티타늄 합금은 높은 spring-back 성질, 초탄성 효과, 형상기억 효과 등의 장점을 가지고 있으나 성형이 어렵다는 단점을 가지고 있다. 본 연구에서는 니켈-티타늄 와이어의 굴곡을 위한 열처리 시에 나타나는 부하-변위 곡선의 변화 및 상전이 온도 변화와 같은 물성 변화 양상을 조사하고자 하였다. 수종의 니켈-티타늄 와이어를 열처리를 시행하지 않은 군, 전기저항 열처리 장치를 이용하여 와이어 단면적에 따라 제조회사에서 권장하는 전류를 기초로 하여 00.016" ×00.022" (5 A, 7 sec), 0.018" × 0.025" (6 A, 7 sec) 그리고 0.0215" × 0.028" (7 A, 8 sec) 와이어를 열처리만 시행한 실험군, 열처리를 시행하여 굴곡을 부여한 실험군 그리고 열처리 시간을 1초 증가시켜 굴곡을 부여한 실험군으로 분류하여 3점 굴곡 실험과 시차주사열량측정을 하여 다음과 같은 결과를 얻었다. 0.016" × 0.022", 0.018" × 0.025" 그리고 0.0215" × 0.028" 니켈-티타늄 와이어에서 굴곡을 부여하지 않고 열처리만 시행한 실험군이 열처리를 시행하지 않은 대조군에 비해 부하-변위 곡선이 상방 이동되어 초탄성 현상에 의한 평탄역(loading and unloading plateau)의 힘이 더 증가되었다. 0.016" × 0.022", 0.018" × 0.025" 그리고 0.0215" × 0.028" 와이어에서 열처리만 시행한 실험군이 열처리를 시행하지 않은 군보다 더 낮은 austenite finish (A_(f)) 온도를 보였다, 0.018" × 0.025" 및 0.0215" × 0.028" 와이어에서 열처리를 시행하여 굴곡을 부여한 실험군은 열처리만 시행한 실험군과 열처리를 시행하지 않은 대조군에 비해 부하-변위 곡선이 상방 이동되었으며, 열처리 시간을 1초 증가시켜 굴곡을 부여한 실험군에서 가장 높은 부하-변위 곡선을 나타냈다. 0.018" × 0.025" 그리고 0.0215" × 0.028" 와이어에서 A_(f) 온도는 열처리 시간을 1초 증가시켜 굴곡을 부여한 실험군에서 가장 낮게 관찰되었고 열처리를 시행하여 굴곡을 부여한 실험군, 열처리만 시행한 실험군 그리고 열처리를 시행하지 않은 대조군 순으로 높게 관찰되었다. 이상의 결과를 종합할 때, 임상에서 니켈-티타늄 합금 와이어에 굴곡을 부여하기 위해 열처리하는 경우 초탄성 특성은 유지될 수 있으나, 부하-변위 곡선의 상방 증가가 나타나므로, 와이어에 의한 교정력이 증가될 수 있음에 유의하여야 한다. Objective: Nickel-titanium alloy wire possesses excellent spring-back properties, shape memory and super-elasticity. In order to adapt this wire to clinical use, it is necessary to bend as well as to control its super-elastic force. The purpose of this study is to evaluate the effects of heat treatment on the load-deflection properties and transitional temperature range (TTR) of nickel-titanium wires. Methods: Nickel-titanium wires of different diameters (0.016" × 0.022", 0.018" × 0.025" and 0.0215" × 0.028") were used. The samples were divided into 4 groups as follows: group 1, posterior segment of archwire (24 mm) without heat treatment; group 2, posterior segment of archwire (24 mm) with heat treatment only; group 3, anterior segment with bending and heat treatment; group 4, anterior segment with bending and 1 sec over heat treatment. Three point bending test was used to evaluate the change in load-deflection curve and obtained DSC (different scanning calorimetry) to check changes in A_(f) temperature. Results: In the three point bending test, nickel-titanium wires with heat treatment only had higher load-deflection curve and loading and unloading plateau than nickel-titanium wires without heat treatment. Nickel-titanium wires with heat treatment had lower Af temperature than nickel-titanium wires without heat treatment. Nickel-titanium wires with heat treatment and bending had higher load-deflection curve than nickel-titanium wires with heat treatment and nickel-titanium wires without heat treatment. Nickel-titanium with heat treatment of over 1 sec and bending had the highest load-deflection curve. Nickel-titanium wires with heat treatment and bending had lower Af temperature, Nickel-titanium wires with heat treatment of over 1 sec and bending had the lowest Af temperature. Conclusion: From the results of this study, it can be stated that heat treatment for bending of Nickel-titanium wires does not deprive the superelastic property but can cause increased force magnitude due to a higher load-deflection curve.

스포츠 에어로빅시 High Kick 동작의 운동학적 분석

우병훈,인희교,이수재 한국운동역학회 2001 한국운동역학회지 Vol.11 No.3

This study serves the purpose of understanding the principles of kicking moves through kinematics analysis on elite sports aerobic athletes making the movement of high kicking. The study also intends to not only help instructors and coaches understand the accurate move of high kick and make a better judgement for athletes but also lay a basic resource for them to rely on. To accomplish all this, the time span of the each phase, the displacement of COG, the velocity of left/right forefoot, the angle displacement of left/right hip joint and the angle displacement of left/right ankle joint have been studied. The conclusions were as follows; 1. It took less time at phase 3(0.40sec) and phase 5(0.40sec) of returning the leg than at phase 2(0.56sec) and phase 4(0.43sec) of kicking up. 2. The displacement of COG was low at phase 1, 3, 5(103.02±5.70, 95.33±2.45, 96.66±3.20 cm) and high at phase 2(111.18±9.97) and phase 4 (111.61±5.62 cm). 3. About the velocity of left/right forefoot, kicking up the right foot was faster than returning it at phase 1-2(1081.63±40.62an/sec) and phase 2-3(992.92±45.68 cm/sec). With the left foot, kicking up was faster than returning at phase 3-4(1116.25±63.46cm/sec) and phase 4-5(1043.63±40.62cm/ sec). 4. The left and right angle displacement of hip joint showed the maximum extension at phase 1(174.4±52.36, 162.6±05.40deg/sec), phase 3 (170.66±5.94, 165.89±4.36deg/sec), phase 5(166.18±4.83, 157.05±3.59deg/sec), phase 2(26.19±5.40deg/sec) showed the minimum angle of the right angle and phase 4(27.67±5.31deg/sec) showed the minimum of the left angle. 5. In the left and right angle displacement of knee joint, the angle displacement on the right knee joint showed the maximum extension at phase 1, 2, 3, 4(169.10±2.96, 169.91±6.20, 153.14±6.32, 162.11deg/sec) and flexion at phase 3(140.45±10.37deg/sec). The left knee joint showed the maximum extension at phase 1, 3, 4, 5(169.15±4.25, 157.99±10.82, 172.14±3.06, 168.72deg/sec) and flexion at phase 2(148.17±9.64deg/sec). 6. The angle displacement on the right ankle joint showed flexion at phase 1, 3, 4, 5(125.15±4.81, 101.66+2.80, 102.88±8.89, 106.27±5.76deg/sec) and the maximum extension at phase 2(152.22±5.18deg/sec) The left ankle joint showed flexion at phase 1, 2, 3, 5(104.90±48.10, 116.06±15.84, 106.55±8.84, 118.79±6.89deg/sec) and showed the maximum extension at phase 4(153.57 ±4.65deg/ sec).
