본 연구는 사회적 배제의 잠재유형을 구분하고 노후의 경제적 불안에 미치는 영향을 실증적으로 분석하였다. 또한 주관적 계층의식에 따라 그 영향력이 달라지는지를 함께 살펴보고자 하였다. 이를 위해 2016년 한국종합사회조사(KGSS) 14차 자료를 사용하여, 조사 당시 기준 만 18세의 성인남녀 1,041명의 응답지를 분석하였다. STATA14와 MPLUS 7 통계프로그램을 이용하여 기술통계분석과 t-test, 잠재계층분석(LCA), 잠재집단에 대한 다항로지스틱분석을 실시하였다. 마지막으로 다중회귀분석을 실시하여 변수 간 영향관계 및 조절 효과를 확인하였다. 연구결과 사회적 배제의 유형은 3집단으로 나타났으며, 사회활동배제집단(49.3%), 다차원적 배제집단(30.9%), 사회 활동 적극집단(19.7%)의 순으로 나타났다. 사회활동배제집단은 경제, 고용, 건강 배제의 가능성이 가장 낮지만, 공식/비공식 사회활동의 배제가 두드러진 집단이며, 다차원적 배제집단은 모든 영역에서 배제를 경험할 가능성이 50% 이상인 집단으로 나타났다. 사회활동 적극집단은 비공식 사회활동에 매우 적극적으로 참여하는 것이 특징인 집단이다. 다항로지스틱 분석결과 사회활동배제집단은 다른 집단에 비해 청년층이 많이 포함되었으며, 다차원적 배제집단에는 배우자가 없는 여성노인이 많이 포함되어 있는 것으로 나타났다. 마지막으로 다중회귀분석 결과 사회적 배제 유형은 주관적 계층의식과 상호작용하여 노후의 경제적 불안에 영향을 미치는 것으로 나타났다. 이러한 연구결과를 바탕으로 노후의 경제적 불안을 예방하기 위한 정책적·실천적 방안을 제언하였다.

Purpose: The aim of this study is to explore different types of self-rated health trajectories among one-person households in Korea. Methods: We used five time-point data derived from Korea Health Panel (2011~2015). A latent growth curve modeling was used to assess the overall feature of self-rated health trajectory in one-person households, and a latent class growth modeling was used to determine the number and shape of trajectories. We then applied multinomial logistic regression on each class to explore the predicting variables. Results: We found that the overall slope of self-rated health in one-person households decreases. In addition, latent class analysis demonstrated three classes: 1) High-Decreasing class (i.e., high intercept, significantly decreasing slope), 2) Moderate-Decreasing class (i.e., average intercept, significantly decreasing slope), and 3) Low-Stable class (i.e., low intercept, flat and nonsignificant slope). The multinomial logistic regression analysis showed that the predictors of each class were different. Especially, one-person households with poor health condition early were at greater risk of being Low-Stable class compared with High-Decreasing class group. Conclusion: The findings of this study demonstrate that more attentions to one-person households are needed to promote their health status. Policymakers may develop different health and welfare programs depending on different characteristics of one-person household trajectory groups in Korea.

Using a data set drawn from 1419 college students, this study analyzes what implications clothing or fashion has on self-expression or image management in Korean society and who are more likely to use fashion as a image management tool in the process of interacting with others. Employing Pierre Bourdieu's concept of capital, we discuss three theories concerning correspondence between class and fashion: the theory focusing on economic capital in emphasizing the correspondence; the theory focusing on cultural capital in emphasizing the correspondence and the theory emphasizing relationships between fashion and other factors rather than class. Based on the theoretical examination, we select independent variables that can be grouped into status/class variables, or economic capital variables(such as subjective status, income, father's education, father's occupation) and socio-cultural variables, or cultural capital variables(such as possession of cultural capital, desire for upward mobility). Upon regressing strategic use of fashion on independent variables, we find that both status/class variables and socio-cultural variables are statistically significant in explaining the strategic mobilization of fashion for one's image production or social success. It shows that class as a form of economic capital has important effects on the strategic use of fashion, and cultural capital also has effects independent of economic capital.

Purpose: The purpose of this study was to develop a PBL module in maternity nursing based on the clinical cases. A PBL module applied to maternity nursing class to test the effects on improving the learning ability of students. And it would be used for developing further PBL module even more perfectly. Method: We selected the concept of the PBL module which is based on the purpose of the contents of maternity nursing class and national test held by Korean Nursing Association. The module scenario was composed up of the cases of clinical practices and was also checked by clinical practice professionals as well as the nursing professionals in other colleges. We used this PBL module for the 20 second grade student nurses in K college for 6 weeks. Besides, we checked self-analyses on the PBL class, assessments done by students on the PBL class itself and on the academic adviser and analyzed the students' subjective statements on the PBL class . Results: The achievements of the experimental students given a PBL class, are better than those of the control group statistically. And the experimental group do their almost all learning planned actively for themselves and show their positive responses on the PBL class being helpful in practicing clinical cases. Conclusion: PBL class could be considered the method to fortify student nurses' abilities on adjusting themselves to clinical real situations through the learning planned by themselves. Afterwards it is necessary to activate PBL class in nurse education. Most of all, it is more important that nurse educators should recognize the values of this PBL class and try to apply it in reality.

Purpose: This study aims to identify the types of health-related quality of life (QoL) based on the EuroQoL 5 Dimensions among community older people and predict the factors affecting these types. Methods: This study used data from the 2016 Korea Health Panel Survey, whose participants included 3,848 older people. The data were analyzed using the software jamovi 1.2.17 and Mplus 8.2 for latent class analysis. Results: The subgroups of the older people's health-related QoL were identified as three latent classes: General stable type (43.9%), pain-related low type (35.0%), and general low type (21.1%). The types and characteristics of health-related QoL among the latent classes differed. Comparing the difference between the general low type and general stable type, the subjects showed higher probability of belonging to the general stable type when they were men, younger, higher education level, employment, better subjective health, lower BMI and stress level, and no suicidal ideation. A comparison between the general low type and the pain-related low type showed that the subjects were more likely to be classified as the pain-related low type when they were younger, higher education, employment, and better subjective health. Conclusion: The results showed a significant heterogeneity in the types of health-related QoL among community older people, and the predictors for each type were not the same. These findings present basic data for cultivating nursing interventions that enhance health-related QoL.

OC-SVM(One Class Support Vector Machine)은 주어진 전체 데이터의 분포를 측정하는 대신에. 데이터 분포의 서포트(support)를 측정하는 기술로서 주어진 데이터를 가장 잘 설명할 수 있는 최적의 서포트 벡터(support vector)를 구하는 기술이다. OC-SVM은 데이터 분포의 표현에 아주 뛰어난 접근 방법이지만, 사람의 주관적인 중요도를 반영하는 것은 힘들다. 본 논문에서는 각 데이터에 퍼지 맴버쉽(fuzzy membership)을 적용하여 기존의 OC-SVM에 사용자의 주관적인 중요도를 표현할 수 있는 FOC-SVM(Fuzzy One class Support Vector Machine)을 유도 하였다. FOC-SVM은 데이터들을 동등하게 다루는 것이 아니라, 데이터 객체의 중요도에 따라 데이터를 다룬다. 즉, 덜 중요한 데이터의 특징 벡터는 OC-SVM의 처리과정에 덜 기여하도록 하기 위하여, 객체의 중요도에 따라 특징 벡터의 크기를 조정하였다. 이를 증명하기 위하여 가상의 데이터를 가지고 실험을 하였고, 실험 결과는 예측된 결과를 보여 주었다.

This case study developed and operated "Fashion & Film" as a fashion-related liberal arts course. The class was designed to include fashion styles exhibitted in films, fashion-related PPL, fashion design through film, fashion images of movie characters, considering gender & color images expressed in movie costumes, and the history of western costumes and asian folk costumes in films. The class was counducted through various teaching methods, such as lectures, student's presentation of movie plots, and team discussions, which created a student-led class. The team presentations at the end of the term were intended to enhance the understanding of fashion through movies. The results of subjective lecture evaluation of "Fashion & Film" showed the most satisfaction with the communication with professor. Students said that it was good to understand fashion through film. They expressed a burden with the team project; however, they were satisfied with the team project outcomes. Students said that PowerPoint was used very effectively. On the other hand, there was an prevelent opinion that the content of PowerPoint and workbook did not match. To address this inconvenience, a textbook called "Fashion in Film" was published and used in the first semester of 2020. The multiple-choice evaluation showed that students were generally satisfied with the "Fashion & Film" class.

Color image quantization is a process of selecting a set of colors to display an image with some representative colors without noticeable perceived difference. It is very important in many applications to display a true color image in a low cost color monitor or printer. the basic problem is how to display 224 colors with 256 or less colors, called color palette. In this paper, we propose an algorithm to design the 256 or less size color palette by using spatial maskin geffect of HVS and subjective distortion measure weighted by color palette by using spatial masking effect of HVS and subjective distortion measure weighted by color activity in 4*4 local region in any color image. The proposed algorithm consists of octal prequantization and subdivision quantization processing step using the distortion measure and modified Otsu's between class variance maximization method. The experimental results show that the proposed algorithm has higher visual quality and needs less consuming time than conventional algorithms.

Auditory experiments based on subjective responses were undertaken for the standard heavy and light weight impact noise. Relations between noise levels and subjective evaluations were also investigated. As a result, it was shown that the noise class was rated with the range of sensible satisfaction by investigating the various social responses for the floor impact noise. The rate classification for the heavy weight impact noise is suggested as a design guide for concrete slabs which satisfy the residents' requirements in various sound insulation capacities of multistory residential buildings.
