탄성파 내삽 기법의 최근 연구방향은 공간적 알리아싱이 존재하는 자료에서의 내삽을 효과적으로 수행하는 것이다. 다양한 내삽 기법 중 기저함수를 정의하여 트레이스를 가장 잘 복원할 수 있는 기저함수의 조합을 찾아내는 Matching Pursuit 내삽 기법이 개발된 바 있다. 그러나 이 방법은 공간적 알리아싱 문제를 해결하지 못하는데 이를 해결하기 위해 다성분 Matching Pursuit 방법이 제안되었고 또한 시간차 보정(moveout correction) 방법도 소개된 바 있다. 다성분을 이용한 방법은 P파만을 갖는 다성분 자료가 획득되어야 하는데 해저면에서 다성분을 측정하는 OBC (Ocean Bottom Cable) 자료의 경우에는 P파 성분만을 분리하는 작업이 어려워 현장자료 적용이 힘들게 된다. 따라서 이 연구에서는 P파와 S파가 혼재하고 공간적 알리아싱이 존재하는 OBC 탐사 자료에서의 효과적인 단일성분 Matching Pursuit 내삽 기법을 다룬다. 이를 위해 시간차 보정을 포함하는 리커 요소파 기반의 단일성분 Matching Pursuit 내삽 기법 작업흐름도를 제안하고 그 효과를 체계적으로 살펴보았다. 이 작업흐름도는 내삽을 적용하기 전에 시간차 보정을 적용하고 다시 역 시간차 보정을 적용하여 공간적 알리아싱 문제를 해결하였다. 제안한 작업흐름도를 OBC 측정을 가정한 합성탄성파탐사 자료에 적용하여 그 효과를 검증하였고 현장자료에 적용함으로써 공간적 알리아싱이 심한 경우에도 내삽이 가능함을 확인하였다.

Projection pursuit(PP) is a computer-intensive method which seeks out interesting linear projections of multivariate data onto a lower dimension space by machine. By working with lower dimensional projections, projection pursuit avoids the sparseness of high dimensional data. We show through simulation that two projection pursuit discriminant mothods proposed by Chen(1989) and Huber(1985) do not improve very much the error rate than the existing methods and compare several classification procedures.

Purpose : This study examined the effects of college students' occupational value and social support on their career decision status. Methods : This research was conducted between May 6 and May 30 in 2023 with 228 college students from city B in South Korea as the study participants. The frequency, percentage, mean, and standard deviation of the collected data were analyzed, while t-test, ANOVA test, Scheffe's test, Pearson correlation coefficient, and a multivariate regression analysis were conducted using the SPSS/WIN 22.0 program. Results : The analysis revealed that the research subjects had an average occupational value of 3.58±.44, social support of 4.18±.56, and a career decision status of 2.82±.59. Notably, a significant difference in the career decision status of the students was observed with regard to their fields of major (F=2.36, p=.019), However, no other variable demonstrated a significant difference. The confidence level pertaining to career decision-making was found to be positively correlated with the pursuit of status and self-direction (r=.25, p<.001), pursuit of creativity (r=.16, p=.017), pursuit of relationship (r=.35, p<.001), pursuit of diversity and change (r=.16, p=17), pursuit of interest (r=.19, p=.003), pursuit of compensation (r=.29, p<.001), pursuit of professionalism (r=.46, p<.001), material support (r=.25, p<.001), appraisal support (r=.35, p<.001), informational support (r=.32, p<.001), and emotional support (r=.29, p<.001). Moreover, the indecision level related to career decision-making demonstrated a positive correlation with the pursuit of excellence (r=.17, p=.010). The factors that affected the confidence level of career decision-making included appraisal support (β=.29, p<.001) and pursuit of compensation (β=.19, p=.003), whose collective explanatory power was 15 %. It was further observed that appraisal support (β=-.27, p<.001), pursuit of professionalism (β=-.16 p=.017), pursuit of excellence (β=.17, p=.005), and the field of major (β=-.16, p=.012) largely influenced the indecision level related to career decision-making, together bearing an explanatory power of 17 %. Conclusion : The results of this study have important implications for enhancing college students' career decision status. Moreover, further research investigating the diverse variables that affect students' career decision status is necessary, along with effective endeavors to improve education and develop programs that positively affect college students' career decision status.

The purpose of this study was to identify imported apparel selection behavior according to Mongol women's conspicuous consumption orientation. A self-administered questionnaire was used for data collection. First, factors of conspicuous consumption orientation were high price and luxury brand, fashion style, altruism, prestige, and brand. Mongol women were segmented into the price and prestige pursuit group, the fashion and brand pursuit group, the altruism pursuit group, and the conspicuous consumption retard group. Second, factors of motivating the selection of imported apparel were value, symbolism, and aesthetics, and Mongol women considered the aesthetics of imported apparel important. Married Mongol women in their 30's chose imported apparel because of its symbolism. More married women selected imported apparel because of its value and more educated women selected imported apparel because of its aesthetics. Women with higher apparel expenditure selected imported apparel because of its value and symbolism. Quality, diversity, and the fit of imported apparel were the selection criteria for Mongol women and they were satisfied with the quality, diversity, and fit of the imported apparel. Brand awareness was very important when selecting imported apparel but the women's satisfaction level was significantly low. Third, more women in their 30's, unmarried, or with a lower educational level were found in the price and the prestige pursuit group, and the price and prestige pursuit group and the altruism pursuit group selected imported apparel for its aesthetics. More unmarried women in their 30's with a higher educational level were found in the fashion and brand pursuit group and selected imported apparel for its value, symbolism, and aesthetics. More unmarried women in their 20's with a higher educational level were found in the altruism pursuit group, but unmarried women in their 20's with a lower educational level were found in the conspicuous consumption retard group.

The purpose of this study was to classify types in sense of gender role identity and to figure out the difference among sociocultural attitude, benefits of clothing pursuit, and appearance management behaviors by sense of gender role identity types. Questionnaires were administered to 455 people in their twenties and thirties living in Daegu and Kyoungbuk area. Data were analyzed by using frequency, factor analysis, credibility, $X^2$-test, ANOVA, Duncan-test, and t-test. The findings are as follows. First, Men of androgyny group showed the highest rate of 38.5% followed by undifferentiation(22.9%), masculineness(21.0%), and feminineness(17.6%). Women of undifferentiation group showed the highest rate of 33.2% followed by feminineness (25.2%), androgyny(22.0%), and masculineness(19.6%). Second, factors of sociocultural attitude were internalization and recognition. Benefits of clothing pursuit consists of the factors such as consciousness of others, personality, and vogue pursuit. Factors of appearance management behaviors were dressing, skin management, plastic surgery management, weight management, health management, and hair management. Third, the result from the difference between sociocultural attitude and benefits of clothing pursuit by sense of gender role identity types, men of androgyny and feminineness showed highest in recognition while women of androgyny showed highest in internalization and recognition. The result of the difference in benefits of clothing pursuit by sense of gender role identity shows that both men and women of androgyny group have high tendency for being conscious of others, personality pursuit, and vogue pursuit while men of undifferentiation and masculineness have low interest in dressing in relationship with others. Fourth, the examination of the difference in appearance management behavior by sense of gender role identity types found men of androgyny group managed dressing, skin, weight, health and hair most while women dress and health most. Men of undifferentiation group managed dressing and weight least, while men of masculineness health, and men of feminineness hair least.

본 논문에서는 추적-회피 게임에서 추적자의 추적성능을 향상시키기 위한 최적화 기법을 소개한다. 제한된 공간상에서 추적자는 도망자를 빠른 시간 내에 찾아내고 잡기 위해 확률맵을 생성하고 그 확률정보를 토대로 탐색한다. 추적자는 기존 global-max와 local-max의 장점을 취한 hybrid 추적방식을 사용하는데 이 추적방식은 global-max와 local-max 성향을 조절하는 가중치를 갖는다. 따라서 상황별 최적의 가중치를 찾기 위해 에피소드 매개변수 최적화 알고리즘을 제안하였다. 이 알고리즘은 가중치에 대한 다수의 추적-회피 게임 에피소드를 반복적으로 수행하는 동안 강화학습을 통해 보상을 누적한 후 해당 가중치의 평균보상을 최대화 하는 방향으로 황금분할법을 사용하여 최적의 가중치를 찾는다. 이 최적화 기법을 이용하여 여러 상황별 최적 추적정책을 찾기 위해 도망자 수와 공간의 크기를 변화시켜가며 각각 최적화를 수행하였고 그 결과를 분석하였다.
