IPO주의 단기성과에 대한 연구는 많이 진전이 되었다. 그러나 장기성과에 대한 연구는 아직 미진한 상태이다. IPO주가 단기적으로는 초과수익을 실현한다는데 대하서는 거의 합일점을 찾은 듯하다. 한국 시장의 경우도, IPO주의 장기성과에 대하서는 3편 정도에 그치고 있다. 본 연구는 IPO주의 장기성과와 대주주의 지분변과의 관련성을 검증하는데 초점을 두었다. 실증 결과로는, 기업은 공개시점을 대체로 그 기업의 기업가치의 최대점으로 잡아 공개를 결정한다는 것과 공개후 5개월이란 시점에서 누족초과수익이 가장 정점을 이루며, 21개월 후에 안정을 찾는데는 경향을 알아내었다. 또한 대주주의 지분을 많이 처분하는 기업의 장기성과가 떨어짐을, 그리고 공개후 시간이 지날수록 장기성과가 떨어짐을 조심스럽게 추론할 수가 있었다.

이 글은 수학적 플라톤주의를 포기하더라도 프레게에게 열려 있었던 것으로 보이는 논리 주의 프로그램의 한 가능성, 즉 수를 고차 개념으로 이해하는 논리주의 프로그램을 그가 왜 선택하지 않았는가 하는 물음에 대답하는 데 목적이 있다. 이를 위해 나는 수를 고차 개념으로 이해할 때 산수의 기초 개념들을 만족스럽게 정의할 수 있는지, 그런 정의들로부터 프레게의 기수 이론의 공리들을 고단계 논리학 내에서 모두 증명할 수 있는지를 차례대로 검토한다. 다음으로 나는 그 검토 결과에 근거할 때 대상들이 무한히 많이 있다는 가정에 의존하지 않는 한 서로 다른 유한 기수들이 무한히 많이 있다는 것을 보증할 수 없다는 점을 논증할 것이고, 바로 그 점이 프레게가 비플라톤주의적 논리 주의를 받아들일 수 없었던 주요 이유였음을 논증할 것이다.

This paper presents that in the Russian Revolution 1) socialist and alternative democratic conceptions between Marx and Lenin are very different, 2) the process and cause of failure of realizing Lenin's democratic alternative conception, 3) the interactive expansion process of the party and the state, 4) the failing process of socialist original accumulation, collectivization, and constructing planned economy. This shows that Russia could not help fail to transit to socialist society due to the combination of wrong conceptions and that new revolution and construction should combine right socialist and democratic conceptions.

A franchisee owner, as an entrepreneur who is independent from a franchisor, has the greatest influence on the success of franchisee business. The effect of the franchisees' entrepreneurship on their performance can be different from that of self-employed business owners, due to the fundamental nature that the franchisor and franchisees share a standardized operation and business risks. Therefore, the purpose of this study is to demonstrate whether or not the relationship between the entrepreneurship and the performance, which has been popularized in general, is displayed in franchised stores as well. The current study analyzed the influence of innovativeness, risk-taking, and proactiveness on franchisees' performance based on the samples from 109 Small Size Educational Services franchisees. The results show that the franchisees' proactiveness is the only variable that affects the performance while the effect of the other variables was not significant. These results make implications that, for their business success, franchisee owners should be proactive in their target market, without compromising the quality of franchisor's standardized products and services by being innovative and risk-tolerant.

The purposes of this study is attempted to determine the effects of Moral sensitivity and nursing Professionalism on Standard Precautions among nursing students. Data collection is executed from November 15th to 30th of 2021, from 170 4th grade nursing students at one school city D. And the data answered to the questionnaire were analyzed by descriptive analysis, t-test, One-way ANOVA, Pearson's correlation coefficient, and Hierarchical Multiple Regression Analysis. As a result of the study, Moral sensitivity of nursing students was 4.96±0.68 out of 7 points, the average of Nursing Professionalism was 3.93±0.61 out of 5 points and the average of Standard precautions was 4.55±0.61 out of 5 points. There was a correlation between moral sensitivity and standard precautions(r=.336, p<.001), between moral sensitivity and nursing professionalism(r=.384, p<.001) and there was a correlation between nursing professionalism and standard precautions(r=.518, p<.001). In additon, It was confirmed that the higher the nursing professionalism of nursing students, the higher the standard precautions(𝛽=.399. p<.001). The explainatoy power of the variables Standard Precautions was 35.7%. Based on the results of this study, it is suggest that develop education program increasing the Standard Precautions by enhancing Nursing Professionalism for infection management educational program among the students.

The purpose of this study is to find out what the contribution of medical service design to improve the quality of medical service has contributed to the resolution of medical authority, and to draw the implications necessary to further develop the medical service industry. As a method of research, first, the concept of medical authority was considered and the internal and external factors of medical authority were examined. Second, by examining the cases of medical service design, which resolved the medical emphasis inherent in internal and external factors, the key points and significance of problem solving were analyzed based on the core results. Third, the implications were to form a patient-centered medical culture for respect and dignity for patients, to break up the conventions inside medical staff to dismantle medical authority, and to establish a fair communication system for sharing medical information.

Selective attention induces perceptual distortions. ranging from repulsion of objects located near the attended area(Suzuki & Cavanagh. 1997) to magnification of the u unattended objects (Tsal & Shalev. 1996). Two hypothetical mechanisms have been p postulated: a shift of receptive fields' positions away from the locus of attention(receptive-field-recruitment hypothesis) or the enlargement of perceived space around the a attended location(space-enlargement hypothesis). The present study distinguished between these hypotheses by investigating the spatial and temporal properties of attention-induced d distortions. Perceptual judgements on vernier alignment. line tilt. line length were used to measure attention-induced changes in perception. Attention was induced exogenously(by blinking a specific set of dots around the test stimuli} or endogenously(by instructing the subject to selectively attend the dots). After inducing attention. the test stimuli were briefly flashed. A staircase method was used to measure the attentional effect. A vertical line was perceived as repelled from the locus of attention. and a line segment appeared longer when attention was given to its vicinity. The effects decreased as the distance between the locus of attention or the time between the onset of attention and the stimulus presentation increased. The results imply that the space-enlargement hypothesis provides a better explanation for the attention-induced changes in perception than the receptive-field-recruitment hypothesis.

Purpose: The purpose of this study is to evaluate correlation between convergence insufficiency and concentration by evaluating attentiveness in children who have convergence insufficiency symptoms. Methods: The CISS survey and examination for the near point of convergence were conducted to 74 in children aged 12 to 13 years in order to divide them into a normal binocular vision (NBV) and a convergence insufficiency (CI) group. The attentiveness examination was used to all subjects to figure out their emotional problems, hyperactivity and impulsiveness problems, and managerial or functional problems with a 5-point scale. Correlation between convergence insufficiency-related symptoms included in CISS and attentiveness problems was analyzed. Results: there were 29 children (39.2%) in the CI group, the mean scores of CISS of the NBV and CI group were $5.91{\pm}3.69$ and $18.31{\pm}7.00$ each (p<0.001). On the survey of CISS symptoms, children in the CI group frequently expressed such symptoms as eye fatigue, loss of attentiveness, blurry vision, and forgetting the line they have been reading. In the attentiveness examination, the CI group ($74.83{\pm}9.83$) gained higher scores in problematic concentration than the NBV group ($46.80{\pm}11.30$). Convergence insufficiency had significantly positive correlation with total attentiveness (r=0.798). Conclusions: In elementary school students, it has been found that when perceived symptoms related with convergence insufficiency are more serious, problematic attentiveness gets serious, too.

This study was conducted to investigate nursing students' safety-climate: perception and performance of standard precautions for healthcare-associated infection control. We also identified actors influencing performance of standard precautions. Data were collected from 246 junior and senior nursing students at nine colleges in D city from July to September, 2016. The mean score of performance was significantly lower than that of perception in all areas of standard precautions. The biggest difference between perception and performance was in the usage of personal protective equipment and safe injection practices. We also detected significant positive correlations among safety-climate, perception, and performance of standard precautions. In the regression analysis, performance of standard precautions was influenced by safety-climate and grade accounting for 10.7% of variance. To improve healthcare-associated infection control among nursing students, safer and more supportive practical environments need to be provided, and new training strategies such as simulation education need to be expanded.

이 논문에서 우리는 집합의 두 점 사이의 관계를 소개하고, '가깝다'와 '충분히 가깝다'의 위상적인 개념을 다양하게 정의할 수 있음을 보인다. 또한 직관주의 논리와 관계가 있는 De Morgan frame을 소개하고 pre-order에 의하여 정의된 동치관계로 만들어진 동치류들의 집합을 기저로 생성된 위상 공간이 extremally disconnected 임을 보인다.
