  • This study is aimed to investigate the association between web-based visual stress and MBTI personality types. The stressor deriving visual stress is built by 14 vowels out of Korean alphabet as a content and parallel striples as a background on the screen, which is given to each subject during 5min. The dependent variable indicating how much human takes visual stress is the reduction rate of flicker fusion frequency, which is evaluated with visual flicker fusion frequency tester. The independent variables are gender and 8 MBTI personality types(E-I, S-N, T-F, and J-P), and hypotheses are based on human information processing model and previous studies. The results address that the reduction rate is not significantly affected by gender, S-N, and J-P, but E-I and T-F have significant influences on it. The reduction rate in I-type is almost 2 times as much as that in E-type and T-type has the rate 2.2 times more than F-type. This study can be applicable to determine the adequate personnel for jobs requiring less sensibility to visual stressors in areas that human error may lead to critical damages to an overall system.

  • The quality assurance activities can detect the factors that affect the quality based on risk identification in the course of mass production. Risk identification is conducted with risk analysis, and the risk analysis method for the rotorcraft landing system is selected by failure mode effects analysis (FMEA). FMEA is a method that detects the factors that can affect the product quality by combining severity, occurrence, and detectability. The results of FMEA were prioritized using the risk priority number. On the other hand, these methods have certain shortcomings because the severity, occurrence, detectability are weighted equally. Dempster-Shafer evidence theory can conduct uncertainty analysis for the opinions with personal reflections and subjectivity. Based on the theory, the belief function and the plausibility function can be formed. Moreover, the functions can be utilized to evaluate the belief rate and credibility. The system is exposed to impact during take-off and landing. Therefore, experts should manage failure modes in the course of mass production. In this paper, FMEA based on the Dempster-Shafer evidence theory is discussed to perform risk analysis regarding the failure mode of the rotorcraft landing system. The failure priority was evaluated depending on the factor values. The results were derived using belief and plausibility function graphs.

  • In some studies regarding acculturation strategies developed Berry(1997), not the preference for integration, but the preference for assimilation showed the best adjustment, which is different from the results of the majority of studies. For the reason of these results, we supposed that when the people of the host society expect the minority members to be assimilated to the host society and the minority members have very similar culture to the host society, the preference for assimilation in the minority members would show the best adjustment. And we tested this hypothesis with Korean-Chinese who had very similar culture to Korean culture and Han-Chinese who had very different culture from Korean culture. For two hundred and twenty five students(63 Korean-Chinese and 162 Han-Chinese), we asked them to complete a questionnaire including Acculturation Strategies Scale, Psychological Well-being Scale, and Depression Inventory. Data from the survey were analysed using two-way ANOVA. As a result, the interaction effect of acculturation strategies and ethnic types affected both of psychological well-being and depression. In details, for Korean-Chinese students, the preference for assimilation showed the highest levels of psychological well-being and the lowest levels of depression, but the preference for integration showed the lowest levels of psychological well-being and the highest levels of depression. For Han-Chinese students, the preference for integration showed the highest levels of psychological well-being and the lowest levels of depression, and the preference for marginalization showed the lowest levels of psychological well-being and the highest levels of depression. We discussed the meanings of the results, implications, and interventions to help Chinese students adjust Korean society.

  • In this study, the test that were used in entrance examination for chemistry class in a Science-Gifted Education Center for middle school students were analyzed by using criteria for identification and measurement of scientific giftedness and a classical test theory. The result of analysis exhibited that most of problems measured more than two elements of scientific giftedness and required applications of scientific knowledge of middle school level to solve problems. In the analysis of sub-elements of scientific giftedness, originality, fluency in creativity and finding problems/formulating hypothesis, planning inquiry, interpreting data in science process skills were dominant while drawing conclusion and generalization processes were lacking. In correlation analysis between total score and each type of problems, total score was most influenced by the problems measuring science inquiry linked with scientific knowledge. Item difficulty is moderately high and item discrimination is moderate.

  • The current paper examines the role of the identity of entrepreneurs in the emergence and evolution of a new organizational form by empirically analyzing the evolution of eBook publishers in Korea from 1996 to 2011. Drawing on the recently developed identity-based theory of organizational form in the organizational ecology literature, we test hypotheses on the effects of focused and diffused organizational identities on organizational founding in an emergent organizational population. The results of our empirical analysis that tested three hypotheses about a positive relationship between focused identity and form emergenceand negative relationships between diffused (horizontal and vertical) identity and form emergence largely supported the argument of identity-based entrepreneurship. General implications are discussed.

  • 적용구문(Applikative Konstruktion)은 타동사 구문의 일종이며 적용동사(Applikatives Verb)는 두 가지 유형으로 나눌 수 있다 적용동사가 자동사에서 타동사화 된 경우면 자동사에서는 없던 직접 목적어를 위한 슬롯이 적용형태소(Applikativmarker)를 통해 생긴다. 타동사에서 적용형태소의 삽입을 통해 변화된 적용동사는 두 개의 직접목적어를 취할 수 있는 동사의 특징을 나타내거나, 동사의 논항구조를 재배열하는 기능을 가진다. '논항구조 재배열'(rearrangement of argument structure)의 가장 전형적인 예는 타동사의 주변적인 참여자(peripherer Partizipant)를 적용동사를 통해 격상(Promotion) 시키는 반면 핵심참여자(zentraler Partizipant)는 격하(Demotion) 되는 구문이다. 즉 비 적용구문의 주변적인 참여자가 적용구문에서는 핵심참여자로서 직접목적어(direktes Objekt)의 통사적 기능을 가지는 것이다. 이러한 현상은 세계 여러 나라 언어에서 찾아 볼 수 있는데 본 논문에서는 독일어, 유카텍마야어, 인도네시아어, 캄베라어를 연구대상으로 삼았으며 이들 각 언어에서 어떤 참여자관계(Partizipantenrelation)가 적용구문의 직접목적어로 표현될 수 있는가를 살펴보았다. 이들 언어에서는 장소(Lokation)>수혜자($Benfizi\"{a}r$) & 수취인(Rezipient) > 동반자(Komitativ) > 기구(Instrument) 등의 순서로 가능하다. 이 것을 페터슨(1999)의 연구결과와 종합하여 살펴보면 적용구문의 직접목적어로 나타날 수 있는 참여자들의 순서는 루라기(2000)에 소개된 참여자의 원인연쇄(Kausale Kette)의 역순과 거의 일치하는 것을 볼 수 있는데 제일 자주 나타나는 참여자를 그 순서대로 보면 다음과 같다: 수혜자($Benefizi\"{a}r$) & 수취인(Rezipient)<장소(Lokation)>동반자(Komitativ) & 기구(Instrument)> 원인(Ursache). 이러한 순서를 우리는 '적용성의 위계'($Applikativit\"{a}tshierarchie$)라 부를 수 있으며 이것을 가능한 많은 언어에 유효한 언어의 보편성 중의 하나가 될 수 있다는 가설을 제기해 본다.

  • This study raised a question about 'how user's psychological value consciousness influences design evaluation and evaluated 14 product samples. Three main categories were chosen to be analyzed; product evaluation by step, value consciousness toward products, and creation of shape image and design evaluation. In order to obtain results, four research hypotheses were established a and case study was conducted as part of 'conclusive research' for verification. 120 university students in their 20s majoring in product design were chosen as testees in a bid to increase the accuracy of data. With data collected, the whole flow was analyzed by simple tabulation and further analysis was carried out in three evaluation items. An analysis method was mainly quantitative, focusing on multivariate analysis like factor analysis, cluster analysis, etc. The empirical analysis of this study was verified at P<.05 significance level and SPSSWIN 12.0 program was used for statistic process. As a result, four conclusions were gained regarding 'user's value consciousness toward products and pattern of design evaluation'.

  • This study was conducted to identify the negative effects of sports sponsorships on consumer attitudes towards sports celebrities and the products advertised by them. The results of this study verified the main effects of sports celebrities' responsibility level on consumer attitudes toward the sports celebrity and his/her products in cases of negative incidents. Furthermore, the moderating roles of sports celebrities' response strategies were identified. Data were collected from 135 undergraduate students in the Republic of Korea using a questionnaire. The data from nine participants were discarded because of disingenuous answers to the questionnaire; thus, the final sample consisted of 126 participants. Multivariate analysis of variance (MANOVA) of the obtained data revealed that a sports celebrity's responsibility level has negative effects on consumer attitude toward the sports celebrity and the product. The moderating effects of the sports celebrity's response strategies were also significant.

  • This study examines the retrieval efficiency of the FRBR-based bibliographic retrieval system. To do this, we built two experimental retrieval systems(a FRBR-based system constructed through FRBRizing algorithms and an OPAC-based retrieval system) using 387 music materials coded in a KORMARC format. Next, we set up six hypotheses and compared these two systems in terms of recall, precision, and retrieval time using 28 participants and a questionnaire with 12 queries. The results show that the average recall value of the FRBR-based system Is higher than that of the OPAC system regardless of query types and the average precision and retrieval time values of manifestation queries of the OPAC system is more efficient that those of the FRBR-based system. This study results can be used to customize digital library interfaces as well as to improve the retrieval efficiency of the bibliographic retrieval system.
