온라인 판매가 무서운 성장세를 보여주고 있음에도 불구하고, 소비자 채널 전환행동 영역에서 오프라인 밴드왜건이 여전히 많은 주목을 받고 있다. 소비자의 오프라인에서 온라인 소매업자로의 전환행동을 탐색하는 기존연구와 달리, 본 연구는 push-pull-mooring 모델을 기반으로 소비자가 온라인에서 오프라인 채널로 전환하는 이유와 시점에 중점을 두어 살펴본다. 따라서, 본 연구는 구조방정식 모델과 SPSS를 이용하여 설립된 연구가설을 검증하였다. 그 결과는 예상대로 push 요인(지각된 위험과 불만족)과 pull 요인(대안매력과 지각된 주인의식)이 모두 소비자의 온라인에서 오프라인 채널로의 전환의도에 긍정적 영향을 미치는 것으로 나타났다. 또한, push 요인과 전환비용간의 상호작용 및 pull 요인과 주관적 규범간의 상호작용을 제외하고, 모든 push 요인과 mooring 요인(전환비용, 다양성 추구 성향과 주관적 규범)간의 상호작용 및 pull 요인과 mooring 요인간의 상호작용이 검증되었다. 마지막으로 시사점과 한계점을 더불어 제시하였다.

We obtain some estimations of the essential norm of a pull back operator induced by quasi-symmetric homeomorphisms. As a corollary, we deduce the compactness criterion of this operator.

Reconstruction for hypopharynx and cervical esophagus after wide resection of extensive hypopharynx and larynx cancers have been used various methods including myocutaneous flaps, gastric pull up, md jejunal or large bowel free graft. Recently, the authors had experienced hypopharynx and larynx cancers with extension to the posterior hypopharyngeal wall and thoracic esophagus. Of course, these reconstructive methods should be selected in accordance with the patient's age, physical status, extend of prim.:W lesion, and defect after on block resection, however, gastric pull up was performed in hypopharynx cancer which had skipped lesion in the thoracic esophagus and jejunal free grafts were performed in case 2, 3 which had a extended lesions to the posterior pharyngeal wall. Some complications were noted, which were successfully stabilized by conservative managements. The gastric pull up and jejunal free graft were considered suitable methods for reconstrunction of hypopharynx and cervical esophagus, however, further studies are necessary about it.

A Land slide in Granitic Gneiss weathered soil was stabilized successfully with soil nailing using 929mm steel bar. To understand the behavior of load transfer between soil and nail, in-situ pdl-out tests were carried out. The strains of steel bars were measured using strain gauges during pull-out tests. Forces-strain data from laboratory tension tests on steel bar and grouted steel bar were examined to compare with those of the pull-out tests. Comparisons were made between the pull-out test results and laboratory test result to understand load transfer mechanism.

In this paper, elastic and plastic adhesion index was very important in deciding adhesive characteristics and varying elastic and plastic index, dimensionless load and pull-off force were analyzed and simulated. Finally, using AFM, experimental surface roughness parameters of substrates and pull-off force between tip and substrates were produced. Using these values, pull-off forces were calculated and were compared with experimental pull-off forces. Through simulation and experiment, it was found that interaction of asperity also had very important influence on adhesive contact.

The main objective of this study is to provide a parametric evaluation of the pull-out response of steel fibers embedded in cementitious matrices. The various parameters controlling the behavior of the bond stress versus end slip relationship are analyzed; their effects on the entire pull-out load versus end slip response and the corresponding pull-out energy up to total pull-out are investigated. Also discussed are the effects of the fiber length, the water/binder ratio of the mixtures and embedded length.

Tracheo-gastric fistula is a very rare late complication of total laryngopharyngoesophagectomy with gastric pull-up procedure. It usually occurs after transhiatal esophagectomy, but it has only rarely been reported after total laryngopharyngoesophagectomy with gastric pull-up procedure. Chronic irritation and gastric ulcer may be the cause of tracheogastric fistula. To prevent fistula formation, active management of gastric ulcer and avoidance of mucosal irritation are necessary. We report a case of a tracheogastric fistula which occurred two years after total laryngopharyngoesophagectomy with gastric pull-up procedure that maybe occurred by chronic irritation and gastric ulcer.

화강풍화토지반(SP)의 밀도와 함수비 그리고, 점성토지반(ML)의 함수비 변화가 불도저 궤도 차량의 주행성능에 미치는 영향을 알아보기 위하여, 강원도 춘천군 역골지역에서 실물크기의견 인력시험을 실시하였다. 시험결과로부터, 최적견인력거동은 함수비 뿐만아니라 밀도에도 크게 영향을 받음을 알았다. 또한, 본 연구에서는 지반상태에 따라서 변하는 견인력거동의 최적점 결정방법을 제안하였으며, 화강풍화토지반의 밀도에 따른 최적견인력과 최적슬립을 구하였다.

Surface permanent magnet-type vernier motors with three magnet array-type rotors (parallel magnetized type, repulsion type, and Halbach type) are compared based on the pull-out torque. It was clarified that increasing the rotor radius increases the pull-out torque at a fixed three-phase alternating voltage. The mechanism for the pull-out torque increase on each magnet array type was different, when the effects of the increase were analyzed based on an induced electromotive force and a synchronous reactance. As a result, the design of the Halbach-type rotor was found to be especially effective for achieving high pull-out torque, because this array type achieves a large induced electromotive force $E_0$ and a small synchronous reactance $x_s$.

Push-pull strength has been found to be associated with various work factors such as height, distance, repetition, duration, posture and individual factors. Therefore, this study was performed to investigate the effect of various work factors on push-pull strength and muscle recruitment pattern. Work factors were consisted of grip height(elbow, shoulder), grip distance(100%, 50%, and 25% of maximum grip distance) and shoulder angle(neutral($90^{\cire}$), and abduction($45^{\cire}$, $0^{\cire}$)) during sitting work. The results showed that the normalized strength and EMG value were higher at the elbow height than the shoulder height, and increased with grip distance and shoulder adduction. The results of ANOVA showed that there was significant difference on muscle recruitment patterns among the task conditions. Therefore, it is necessary to consider work factors as well as strength to prevent workers from work-related injuries.
