퍼지 균등화는 어의론적으로 의미있고, 실험적으로 의미있는 언어레이블을 붙이도록 하는 조건이다. 지금까지 발표된 퍼지 균등화조건을 갖는 퍼지분할을 생성하는 알고리듬은 주어진 데이터에 대하여, 오직 하나의 퍼지분할만을 생성할 수 있었다. 만일 생성된 퍼지 분할이 더 이상 유용하지 못한 것으로 판명되면, 이 알고리듬은 주어진 데이터에 대한 퍼지 균등화조건을 갖는 또 다른 퍼지분할을 생성할 수 없다. 이는 생성된 퍼지분할을 사용하여 탐색적 발견을 수행하는 데이터마이닝의 경우 더 이상 프로세스가 진행되지 못함을 의미한다. 본 연구에서는 주어진 데이터에 대한 퍼지 균등화조건을 갖는 서로 다른 두 퍼지분할이 존재한다면, 어떠한 관계가 있는지를 증명하고, 이를 위치적 특성으로 서술한다. 또한 이 특성을 이용하여 퍼지 균등화조건을 갖는 퍼지분할을 원하는 만큼 생성할 수 있는 알고리듬을 제시하고, 예를 들어 설명한다.

본 연구는 최근 자연어 인공지능 연구 동향에 발맞추어 사전 학습된 언어 인공지능을 활용한 의미론적 분석을 통해 국문 보고서의 가독성을 평가하는 방법론 두 가지를 제안한다. 연구진은 연구 과정에서 사전 학습된 언어 인공지능을 활용해 추가 학습 없이 문장을 임의의 벡터값으로 임베딩하고 이를 통해 1. 의미론적 복잡도 와 2. 내재적 감정 변동성 두 가지 지표를 추출한다. 나아가, 앞서 발견한 두 지표가 국문 보고서의 가독성과 정(+)의 상관관계에 있음을 확인하였다. 본 연구는 통사론적 분석과 레이블링 된 데이터에 크게 의존하던 기존의 가독성 평가 방법론으로 부터 탈피해, 별도의 학습 없이 기존 가독성 지표에 근사한다는 점에서 의미가 있다.

Objectives: To examine a defect in inhibitory gating of auditory evoked response in schizophrenics, to compare P3 latency and amplitude in negative and positive schizophrenics, and to assess the association of P3 with family history of the psychiatric disorders, electroconvulsive therapy, and clinical features. Methods: 54 schizophrenics(male 31, female 23) and 75 controls(male 33, female 42) were tested with event-related potential paradigm designed to elicit P3 response and Frankfurter Beschwerde Fragebogen. Results: In schizophrenics, the latency of P3 was significantly more delayed and the amplitude of P3 was significantly more reduced than in the controls. Significant differences in P3 latency and amplitude between negative and positive schizophrenics were not found. And significant difference in the P3 latency and amplitude between schizophrenics with family histories of psychiatric disorder and those without family histories of psychiatric disorder was not found also. The P3 latency and amplitude was not significantly related with electroconvulsive therapy and other clinical features such as age, duration of illness, onset of inllness, number of admission, and doses of antipsychotics etc. Conclusion: These results suggested that schizophrenics had a dysfunction in the process of selective attention and that P3 was not significantly related with family history of the psychiatric disorders, positive and negative symptoms, electro1convulsive therapy, and clinical features in schizophrenics.

This questionnaire study examined the processes linking complexity of self-construal to self-positivity conceptualized as taking multiple perspectives, self-acceptance and self-regulation that, in turn, affect psychological well-being among people with an experience of life-crisis during adulthood due to physical disability or divorce. Data were drawn from 359 adult Koreans residing in Seoul metropolitan area, including the physically disabled, the divorced, and their counterparts without a life-crisis experience during adulthood for comparison. On average, the life-crisis experience group(LEG) had a higher independent selfconstrual and a lower interdependent self-construal than the comparison group(CG). As predicted, complexity of self-construal contributed to taking multiple perspectives that helps searching for meaning, and this, in turn, was found to foster self-acceptance and self-regulation. Through these variables except self-regulation, complex self-construal contributed to psychological well-being as manifested by a higher level of positive emotion and a lower level of depression. As expected, while taking multiple perspectives fostered positive emotion both directly and indirectly through self-acceptance among LEG and CG, only in LEG it directly reduced depression. The comparative approach employed in this study enabled to discern that taking multiple perspectives promotes psychological well-being in LEG by contributing to both meaning making and positive attitude, whereas it promotes psychological well-being in CG primarily by fostering positive attitude. Finally implications for this study were discussed and directions for future research were suggested.

This study intends to find the meaning of signs' configuration in Korean and British school uniform advertisements, to investigate through reproduction of such signs what influences on students' identity issues are, and to discover the cultural significance of the both nations by analysing sexuality discourses around these ads. The authors apply semiotic analysis methods such as two-stage meaning structure and critical discourse analysis. The research subjects are School uniform advertisements of both in South Korea and in the UK. Through this study, women objectification, the power imbalances between men and women, and child erotica were revealed, and also the uniforms of the meaning and value turned out to be distorted. In addition, on the basis of critical discourse analysis, two nations' school uniform ads, which heavily focused on sexual objectification and commercialism, transformed aspects of unusual esthetic value, reminded of Lolita fantasy, implied wrong justification of deviant sexual orientation, and, caused Korean and British students the confusion of sexual identity and values.

The aim of this study is to identify the effects a gratitude promotion program has on the meaning of life and the subjective sense of well-being in female college students. As a result, it was discovered that of the sub-areas of the meaning of life in female college students, the meaning of finding and the meaning of pursuit showed a significant difference. It was also discovered that satisfaction in life of the sub-areas of positive subjective sense of well-being in female college students, love and joy of the sub-areas of subjective sense of well-being, and shame and sorrow of the sub-areas of negative emotional area had statistically significant differences. Such results suggest that the gratitude promotion program has a significant effect on the meaning of life and the subjective sense of well-being in female college students. For higher meaning of life and subjective sense of well-being in female college students, further studies on organized gratitude promotion programs and their usability should be performed.

The subjects of analysis in this paper, the clan name roots "Baj," "Kim," and "Shama/Sama," while distributed commonly among the Altai, Ye i, and isolated language groups, are most widely distributed among the Evenki. The clan name root "Baj-" is widely distributed among indigenous Siberian nations, but is most frequently found among the Manchu-Tungus, especially the Evenki. Therefore, it appears that clans with this root originated from Pribajkal'e, known to be the origin of the Evenki, and spread widely among the nearby Buryats, Mongols, and Yakuts, later spread east to the Nivhi of the Amur River, to the Enisej Protoasiatic language nations such as the Yukaghir or Ket to the north, and the Samoyed language group nations such as the Ne and Selkup. According to the analysis results in this paper, the Evenki clan name "Kim" has the meaning of "person," but also is somewhat associated with gold, metal, or stone. On one hand, while the origin of the clan name "Kim" cannot be clearly established, the clan was assimilated into the Evenki near in ancient times, after which the clan name became widely known among the Manchu-Tungus nations, and furthermore in the Turk nations. The clan name Shama/sama is widely spread across Siberia, including the Manchu-Tungus language group nations of the Altai language family, the Turk language family, and the Samoyed language groups of the Ural language family. Moreover, this clan name is not associated with famous mythic ancestors or heroes of historically famous Asian nations, and it cannot be translated into contemporary language; thus the identification of the meaning and origins of this word is by no means an easy task.

purpose of this study is to investigate the relationship between high school students' Problem Finding Ability (PFA) and chemistry problem solving ability. To achieve this purpose, the interrelationship between the results of PFA in ill-structured scientific problem situation and the scores of sham examination in chemistry I of College Scholastic Ability Test (CSAT) was analyzed. The results of this study turned out to be as follows: There was correlation (r=.346) between the score of PFA test and that of sham examination in chemistry I of the CSAT. And a little correlation (r=.390) between PFA and students application ability which is one of the sub factors in sham examination of the CSAT. Especially, in the high achievers group there was high correlation (r=.446) between students fluency which is one of the sub factors in PFA, and application ability. This implies that the application ability of high achievers has something to do with their PFA for a variety of problems. As for the PFA between high achievers and low achievers, there was no significant difference (t=.830, p=.411).

본 연구는 주가지수 선물시장이 도입된 1996년 5월 3일부터 1998년 12월 5일까지 1분 간격 KOSPI 200 선물가격과 현물가격의 거래자료를 이용하여 각 선물가격과 기초자산가격간의 관계와 상호작용을 검토하는데 있다. 특히 본 연구는 차익거래자나 초단기 투기자(scalper)들이 거래체결을 위해 촌각을 다투는 선물시장의 거래행태에서 볼 때, 경제적 의미를 부여할 수 있는 1분 간격 수익률 자료를 이용함으로써 시장참여자의 실제 거래에서 표출되는 정형화된 현상을 정확히 파악한다는 점에서 중요하다. 본 연구의 주요 결과를 제시하면 다음과 같다. 첫째, 주가지수 선물시장과 현물시장간에 체계적이고 긴 선도-지연 관계가 발견되었다. 주가지수 선물가격의 변화가 현물가격의 변화를 대략 26분 정도 선도하고 있으며, 대략 5분 정도 현물시장의 선도효과도 발견된다. 따라서 KOSPI 200 선물수익률과 현물수익률간의 선도-지연 관계는 한 시장에서 다른 시장으로의 일방적인 것이 아니라 시장간의 피드백(feedback)효과가 존재하며, 선물의 선도효과가 지배적인 것으로 보인다. 이러한 선도-지연 현상은 노이즈에 의한 비동시거래보다는 거래비용과 공매제약 차이 등 각 시장의 제도적 차이에 의해 발생하는 것으로 보여진다. 둘째, 약세시장 하에서 선물의 선도효과가 더욱 크게 나타났다. 이러한 현상은 약세시장 하에서 현물시장의 공매제약이 선물가격과 현물가격간의 괴리를 더욱 크게 하여 선물가격이 현물지수를 더욱 선도하게 하는 요인이 될 수도 있음을 나타내는 것이다. 셋째, 만기별 하위기간 중 97년 6월과 97년 12월을 제외한 기간은 선물과 현물가격간에 장기 안정적인 균형관계가 성립함을 발견하였다. 넷째, ARMA(p, q) 여과를 거친 선물과 현물수익률을 이용하여 97년 6월과 12월은 백터자기회귀(VAR)모형, 그 외의 기간은 오차수정(EC)모형으로 추정하였다. 표본전체기간동안 장기균형오차에 대한 조정은 선물과 현물시장에서 동시에 이루어지고 있으며, 시장간에 발생하는 불균형 상황은 아비트라지 거래로 조정되고 있음이 발견되었다. 각 만기별 모든 하위기간에 있어서는 시장간의 장기 불균형 상황이 현물시장을 통해서 조정되고 있으며, 시장이 성숙된 최근의 만기 98년 12월 하위기간에서는 선물의 15분 선도효과와 현물의 1분 선도효과가 발견되어 선물의 선도효과가 지배적임을 발견하였다.
