최근 소비자의 욕구가 복잡해지고 까다로워지면서 점차 기업환경이 고객중심으로 빠르게 변화하고 있다. 이에 기업은 시장 및 고객의 욕구변화를 포함하는 무한경쟁 시대에 생존하기 위해, 고객 지향적이며 기업의 지속성을 강조하고 있다. 고객의 다양한 욕구를 충족시키기 위해서는 고객의 만족에서 머무는 것이 아니라 고객감동을 제공해야 한다. 고객감동의 증대가 고객충성도에 미치는 영향을 알아보고자 하였다. 본 연구에서는 첫째, 고객만족과 고객감동의 영향을 받고 있는 고객충성도는 재구매의도에 영향을 미치고 있으며, 둘째, 고객만족 수준이 기대이상이면 고객감동에 영향을 주는 것으로 나타났으며, 고객감동의 중요한 요인으로는 고객의 기쁨을 확인하였다. 셋째, 고객충성도는 고객 유지를 강화시키는 것으로 고객감동 요인 중 관심에 영향을 받는 것으로 나타났다. 마지막으로, 고객만족과 고객감동이 고객충성도의 재구매와 고객유지를 향상시키는 것으로 나타났다.

지반의 투수특성은 다양한 지반구조물의 설계 및 해석에서 중요한 지반물성이다. 특히 불포화 상태에서 모관흡수력의 영향을 받으며 모판흡수력 증가에 따라 감소하는 경향은 함수특성 변화와 유사하다. 불포화 투수계수는 실내실험을 통해 직접적으로 구하거나 함수특성곡선으로부터 유추된 이론식을 통해 간접적으로 얻을 수 있다. 본 논문에서는 국내 7개 지역에 대한 시료를 대상으로 함수특성실험과 본 연구에서 개발한 불포화 투수실험 장비를 이용하여 불포화 투수실험을 실시하였다. 지반의 함수상태를 나타내는 함수특성곡선이 불포화 투수계수와 밀접한 관련이 있으므로 함수특성곡선으로부터 불포화 투수곡선을 유추하는 여러 모텔 결과와 실험결과를 비교하였다. 그러나 기존의 추정방법은 국내지반의 투수특성을 잘 표현하지 못하고 있다. 따라서 국내 풍화토의 불포화 투수곡선을 정확히 유추하기 위하여 보정계수를 적용하여 FXK-M 투수모델을 제시하였고 보정계수를 함수특성곡선의 공기함입치로부터 산정할 수 있는 수식을 제안하였다.

Customer Satisfaction (CS) in Auto insurance market is the important factor which makes customer loyalty and retention increase. Recently On-line companies are threatening the existing Off-line companies with taking advantage of the low price through cut-offing the price by internet marketing. Therefore, the CS is becoming an indispensable survival strategy to the Off-line companies. Under these circumstances, this study finds out what the CS factors are in the auto insurance market, and produces levels of CS, customer loyalty and satisfaction Index of each category. The purpose of this study is to suggest the strategic improvement factor for elevating CS level and strategic direction for CS management by CS portfolio analysis based on the survey result.

The separation of tryptophan enantiomers was carried out with medium-pressure liquid chromatography using BSA (bovine serum albumin)-bonded silica as a chiral stationary phase. The influence of various experimental factors such as pH and ionic strength of mobile phase, separation temperature, and the presence of organic additives on the resolution was studied. In order to expand this system to preparative scale, the loadability of sample and the stability of stationary phase for repeated use were also examined. The separation of tryptophan enantiomers was successful with this system. The data indicated that a higher separation factor (a) was obtained at a higher pH and lower temperature and ionic strength in mobile phase. Addition of organic additives (acetonitrile and 2-propanol) in mobile phase contributed to reduce the retention time of L-tryptophan. About $30\%$ of the separation factor was reduced after 80 days of repeated use.

Existing numerical models for strain-hardening cement-based composites (SHCC) are short of providing sufficiently accurate solutions to the failure patterns of coupling beams of different designs. The objective of this study is to develop an effective model that is capable of simulating the nonlinear behavior of SHCC coupling beams subjected to cyclic loading. The beam model proposed in this study is a macro-scale plane stress model. The effects of cracks on the macro-scale behavior of SHCC coupling beams are smeared in an anisotropic model. In particular, the influence of the defined crack orientations on the simulation accuracy is explored. Extensive experimental data from coupling beams with different failure patterns are employed to evaluate the validity of the proposed SHCC coupling beam models. The results show that the use of the suggested shear stiffness retention factor for damaged SHCC coupling beams is able to effectively enhance the simulation accuracy, especially for shear-critical SHCC coupling beams. In addition, the definition of crack orientation for damaged coupling beams is found to be a critical factor influencing the simulation accuracy.

Water condensate accumulated on the surface of a fin-and-tube heat exchanger significantly affects its thermal and hydraulic performance. The purpose of this study is to investigate the effect of condensate retention on the air-side heat transfer performance and flow friction. Total 12 samples of slit and plate fin-and-tube heat exchangers with varying fin spacing and number of tube rows are tested under dry and wet conditions. The thermal fluid measurements are made using a psychometric calorimeter. Frontal air velocity varies in the range from 0.7 m/s to 1.5 m/s. Using the experimental data, presented are the heat transfer coefficients in terms of Colburn j-factor and friction factor.

The aim of this paper is to examine the factors that could influence leadership development and employee retention in private sector organizations. In this research, we will seek to determine the nature and extent of the impact of professional training on leadership development. This research project is one of the new topics that some researchers have started in recent years. the novelty of this subject is the inclusion of the vocational training factor. This factor is likely to have a positive impact on leadership development. Some of the factors already known for their impact on leadership development such as personality, power, and material and moral incentives will be adopted. It is assumed that the results of this research will have a positive impact on the development of leadership within companies.

최근 웹 기반 학습의 장점을 극대화하고 단점을 극복하려는 연구가 많이 진행되고 있다. 하지만 웹 기반 학습의 문제점은 학습자의 중도 탈락률이 높다는 것이다. 교실 환경 수업에서 학습자의 만족도와 학습 유지 간에는 높은 상관관계가 있음이 알려져 있다. 과거 웹 기반 자기조절학습 시스템이 많이 연구되어 있으나 학습자 만족도와의 관계를 깊이 분석한 연구는 미비하다. 본 연구에서는 웹 기반 학습 환경에서 학습자 만족도에 영향을 미치는 자기조절학습 요인들을 도출하고 분석하였다. 웹 기반 자기조절학습 시스템을 학생들에게 적용한 결과 자기평가, 목표설정 및 계획, 정보탐색, 사회적도움, 자료검토이 직접적으로 학습자 만족도에 영향을 주는 것으로 나타났다. 본 연구에서 제시한 만족도 요인을 고려하여 학습 시스템을 개발한다면 학습 유지에 도움을 줄 것으로 기대된다.

Purpose: This study aimed at applying a standardized nursing process to adult surgery patients of post anesthetic care unit, and examining the validity of linkages in the measuring index of nursing outcome by which nursing outcome was applied. Method: The subjects were 184 surgery adult patients admitted at the post anesthetic care unit of Y university hospital. This study was used the measured tool developed by Choi et al.(2004) and by Lee (2004) who had already verified a validity based on Johnson and Bulechek's study(2001). Results: The nursing diagnosis of an acute pain, an urinary retention, a nausea, a decreased cardiac output, an ineffective airway clearance and an ineffective airway clearance were used in taking care for patients. The related factors according to the main nursing diagnosis were as the following: an injurious physical factor in an acute pain, reflex are inhibition in an urinary retention, post surgical anesthesia in a nausea, stroke volume change in a decreased cardiac output, secretory stasis in an ineffective airway clearance, pain in an ineffective breathing pattern. Conclusion: The study results could be facilitated in nursing process application for nurses at post anesthetic care unit. Also this study would provide basic data to develop a computerized program for the improvement of nursing process application.
