  • Purpose: The purpose of this study was to investigate the effects of the information providing program of $I^{131}$ treatment on the pre-treatment anxiety and immune response of patients with thyroid cancer. Method: The used design was a nonequivalent control group design with pretest and post-test. Subjects of this study were 54 patients who had received a total thyroidectomy. They were given a information providing program with a brochure before 4 weeks of the hospitalization for $I^{131}treatment$, with problem solving phone counseling before 2 weeks of the hospitalization. Collected data were analyzed using the SPSS WIN program. Result: Hypothesis one, "The anxiety score of an experimental group would be lower than the score of a control group" was supported(t = -2.12, p = .03). Hypothesis two, "The level of cortisol of an experimental group would be lower than the level of a control group" was supported(t = -3.19, p = .00). However, hypothesis three "The level of T, B and N-K cells of an experimental group would be higher than the level of a control group" was not supported. Conclusion: The information providing program of $I^{131}$ treatment effectively decreased the anxiety of patients with thyroid cancer.

  • This study carried out empirical analysis of the effect on conspicuous consumption and purchase intention by social face sensitivity of customers who have eaten at luxury restaurants. Adult male and female customers aged 20~60 years who lived in Seoul and who had experience eating at luxury restaurants were selected as survey participants. The results of this study are as follow. First, social face sensitivity factor had a significant effect on preference for famous brands and seeking fashion. On the other hand, among social face sensitivity factors, shame consciousness had a significant effect on other-oriented conspicuous consumption. Thus, the hypothesis was partially accepted. Second, among social face sensitivity factors, other-conscious social face had a significant effect on purchase intention. Thus, the hypothesis was partially accepted. Third, preference for famous brand and seeking fashion had a significant effect on purchase intention. However, other-oriented conspicuous consumption tendency had no effect on purchase intention. Thus, the hypothesis was partially accepted. If studies on various consumption sentiment variables continue to be made, these may be usefully utilized for establishing marketing strategies of companies.

  • Objectives : This study was conducted to understand 4 groups in tentatively named "muscle coordinative manipulation" by Korean medicine. Methods : We researched some articles on meridian-muscle theory and muscle's action that are classified into 4 groups in muscle coordinative manipulation. Results : The outcome of examining the hypothesis is as follows: 1. The 1st hypothesis : 'Elevated shoulder' group mainly consists of muscles that are involved with shoulder elevation, abduction and external rotation. 'Lowered shoulder' group is mainly composed of muscles that acts of shoulder depression, adduction and internal rotation. 'Elevated pelvis' & 'Lowered pelvis' groups didn't show significant features by the movement of the hips. 2. The 2nd hypothesis : Most of muscles in 'elevated & lowered shoulder' groups are classified into 'hand taiyang' meridian-muscle. Most of muscles in 'elevated pelvis' group are included in 'foot jueyin' meridian-muscle. Most of muscles in 'lowered pelvis' group are classified into 'foot taiyang & foot yangming' meridian-muscle. Conclusions : There is no significant classification in muscles that comprise 4 groups in muscle coordinative manipulation when it comes to meridian-muscle theory and muscle function. More studies on chain reaction of muscle and subsequent analysis in Korean medicine are needed.

  • The purpose of this study is to verify the relationship between the entrepreneurship and management strategy perceived by the members of SMEs and their organizational performance. First, as a result of the hypothesis that the entrepreneurship of one hypothesis had a significant influence on organizational performance, risk sensibility, progressiveness, and innovation, which are entrepreneurship, had a positive influence on both financial and non-financial performance. Second, as a result of verifying the influence relationship of the hypothesis two entrepreneurship on the management strategy, risk sensibility, progressiveness, and innovation, which are entrepreneurship, were statistically significant for the management strategy, cost advantage strategy, differentiation strategy, and centralization strategy. Therefore, in order to practice management strategy based on entrepreneurship, it was analyzed to influence mutual cohesion. Third, the management strategy showed a positive influence on organizational performance. In particular, only the centralization strategy, a type of SMEs' management strategy, confirmed the positive impact on the financial and non-financial performance. Therefore, the importance of entrepreneurship and management strategy has been emphasized in order for SMEs to create organizational performance through the advancement of sustainability management system.

  • Evolutionary operation (EVOP) proposed by Box (1957) is a method for continuous monitoring and improvement of a full-scale manufacturing process with the objective of moving the operating conditions toward the better ones. EVOP consists of systematically making small changes in the levels of the two or three process variables under consideration. Data are collected on the response variable at each point of two level factorial design with the center point and a cycle is said to have been completed. The cycles are replicated sequentially until the decision is made on whether further cycle of experiments is needed to conclude the significance of any of main effects or interaction effects or the curvature. In this paper, an improved flow chart of EVOP is proposed and how to determine the number of cycles is studied based on the size of type II error. In order to reject the alternative hypothesis of interests with more confidence and conclude that we believe in the null hypothesis of no effects, we propose a counter measure $p^*-value$ corresponding to the p-value. The relationship of $p^*-value$ to the probability of type II error ${\beta}$ under the alternative hypothesis of interests is analogous to that of p-value to the probability of type I error ${\alpha}$. Also the implementation of EVOP with a mixture experiment is discussed.

  • This study aims at finding relationships between the competitiveness of cities and the size or distance of them, based on some premises; (1) the competitiveness can be measured on the interval-ratio level, that is, factor scores, (2) a hypothesis that the spatial interaction model is valid for the relationships can be generally accepted. Based on the general recognition a research hypothesis that the more is the population or the nearer is the distance from a central city the higher is the competitiveness score is constructed. According to the premises 5-factor scores and composite score are calculated by means of regression method, and the scores are regressed on cities' populations and distances from Seoul city. Using bootstrapping method for the tests of significance is effective due to small sample of 21 cities. Results of the analyses show that most aspects of the hypothesis should be rejected or adjusted. Scores on Health-welfare factor, public service factor, and commercial vitality factor have no relation to the cities' sizes or distances. But the results also find the facts that the strong (negative) relationships exist between (1) educational base factor score and population, (2) density factor score and distance. Although this study improves systematic and analytic understanding of spatial interaction patterns, the understanding should be invalid for the general context because it has used the data on 21 cities in the capital region at the time of 2009.

  • 본고에서는 한국의 증권시장과 일본의 증권시장이 같은 공매시장(Auction markets)의 형태라도 거래되는 시점에 따라 다른 거래제도에 따라 가격이 결정되는 점도 있어 각 시점별로 양 시장의 주가행태를 가격조정모형을 통하여 비교 분석하였다. 일반적으로 한국과 일본 모두 오전 시가 수익률의 분산이 종가 수익률에서의 분산보다 크고 또한 오전 시가 수익률의 분산이 다른 시점의 수익률의 분산 보다 켰다. 한국 및 일본 양 시장에서 시가수익률의 분산과 음의 시계열상관계수에서 공히 거래정지기간에 따른 노이즈 항목과 거래오류영향을 발견하였다. 그러나 한국시장에서 거래오류나 노이즈가 일본시장보다 큼을 알 수 있었다. 두 시장에서 모두 오전개장과 오후개장을 다른 시점과 비교하면 주가의 과다반응을 추정 할 수 있으나 일본시 장의 경우는 한국시장에서 보다 미미하였다. 한국시장의 경우 오후종가가 영과 통계학적으로 크게 다르게 양의 수를 가지고 있음은 시장의 효율성에서 한국시장이 일본시장에 비해 떨어지고 시장 정보에 대하여 주가의 가격조정속도가 늦다고 추정할 수 있었고 이는 한국시장이 아직은 일본에 비해 가격제한폭이나 그밖에 거래제한 요소가 일본보다 크기 때문으로 추정된다. 한국시장에서는 주식수익률의 변동성은 노이즈거래가설(Noise trading hypothesis)이 더 설명력이 있다고 추정되고 일본의 경우 사적정보가설(Private information hypothesis)과 노이즈거래가설(Noise trading hypothesis) 둘 다 설명력이 있지만 전자가 더 우위일 가능성이 있었다. 결론적으로 위의 결과를 종합하면 거래메커니즘 차이가 주가의 행태에 크게 다르게 미친다고는 할 수 없고 단지 주가의 정보전달 속도 및 노이즈 그리고 시장의 효율성에 따라 주가행태에 어느 정도 차이를 일으킨다고 할 수 있었다.

  • 차량 인식 기술은 지능형 자율주행 차량 및 첨단 운전자 보조 시스템 (ADAS: Advanced Driver Assistance System)의 개발에 있어서 핵심 요소 기술이다. 영상 기반의 차량 검출 알고리즘은 일반적으로 가설 생성 (HG: Hypothesis Generation) 단계와 가설 검증 (HV: Hypothesis Verification) 단계로 구성된다. 가설 검증 단계는 관심 영역 (ROI: Region of Interest) 내에 차량이 존재할 가능성이 있는 후보 영역을 만드는 단계로서 전체 알고리즘의 복잡도와 성능에 영향을 미친다. 본 논문에서는 관심 영역 내에 존재하는 그림자와 차량으로 인한 에지를 검출하고 두 특징 정보를 결합한 가설 생성 방법을 제안하고 차량 후방 영상을 이용하여 사각지대를 감시하는 시스템에 제안 방법을 적용하는 실험을 수행하였다. 실험 결과로 제안 방법이 차량 후보 영역의 존재 여부와 위치 정보를 판단하기에 적합하며 이를 통해 차량 검출 알고리즘의 계산 복잡도를 개선하면서도 다음 단계인 가설 검증 시 검출 성능을 향상시킬 수 있음을 확인하였다.

  • This research identifies the relation between the quality of cabin service(personnel and material services) in Korean low-cost airlines and resulting customer satisfaction and loyalty. Its aim is to provide low-cost airlines' international flights with basic information when building strategies, and to suggest a strategic implication for an original and competitive cabin service policy that can enhance customer retention. As a result of the analysis, first, hypothesis 1 on relation between the quality of Korean low-cost airlines' cabin service and customer satisfaction was all valid. Moreover, it was coherent with the results of previous researches. Second, hypothesis 2 on relation between the quality of Korean low-cost airlines' cabin service and customer satisfaction was also valid and coherent with previous studies. Third, hypothesis 3 on relation between customer satisfaction and loyalty was valid and coherent with existing studies. Consequently, this research suggests that in order to achieve the continuous retention of loyal customers through customer satisfaction, the quality of personnel and material service has to be considered primarily. In addition to that, this research also suggests that the original and competitive service marketing of low-cost airline is necessary for an airline to continue its profit-making.
