The purpose of this study was to analyze the structure of consumption emotions that consumers experienced in the process of consuming apparel products. Data was collected from 144 female college students living in Busan, and analyzed by salience, diversity, H-index, Clamor's V, and multi-dimensional scaling. The results showed as following; 1. The consumption emotions related to apparel products appeared three dimensions; ‘Relaxed-tense’ dimension, ‘Pleasant-unpleasant’ dimension, and ‘Outward-inward’ dimension. Considering elements of consumption system, the dimensions of consumption emotions in relation to apparel performances were 'Pleasant-unpleasant' and ‘Outward-inward’. The dimensions of consumption emotions experienced in usage situations were ‘Relaxed-tense’ and ‘pleasant-unpleasant’. The consumption emotions related to specific products were composed of ‘Pleasant-unpleasant’ dimension and ‘Outward-inward’ dimension. 2. As the multi-dimension map of this study has much space, it suggested that the scope of consumption emotions related to apparel products was more limited than those related to general situations and products. 3. The structure of consumption emotions in relation to apparel performances appeared to be bisected, while those related to usage situations showed relatively to be dispersed. 4. Although Pleasant-unpleasant dimension was consistent with results of prestudies, the dimensions of ‘Relaxed-tense’ and ‘Outward-inward’ were newly confirmed as the dimensions of consumption emotions related to apparel products. Therefore, consumer's consumption emotions of apparel products were composed of three dimensions, tended to be more limited than those of general consumption situations and products, and differentiated across apparel performances, usage situation, and specific products.

본 논문은 Isomap 알고리즘을 사용하여 다량의 고차원 얼굴 모션 데이터를 2차원 평면에 분포시키는 방법론과, 사용자가 이 공간을 항해하면서 원하는 표정들을 선택함으로써 실시간적으로 얼굴 표정 제어가 가능한 사용자 인터페이스 기법에 대하여 기술한다. Isomap 알고리즘은 세 단계의 과정으로 처리된다. 첫째, 각 표정 데이터의 인접표정을 정의하고, 둘째, 각 표정들 사이의 다양체 거리를 계산하여 표정공간을 구성한다. 표정공간의 생성은 임의의 두 표정간의 최단거리(다양체 거리)의 결정으로 귀결되고, 이를 위해 플로이드 알고리즘을 이용한다. 셋째, 다차원 표정공간을 가시화하기 위해서 다차원 스케일링을 사용하며, 2차원 평면에 투영시킨다. 인접표정을 정의하기 위한 최소 인접거리는 피어슨의 상관계수를 이용한다. 3차원 아바타의 얼굴 표정 제어는 사용자 인터페이스를 사용하여 2차원 공간을 항해하면서 실시간으로 제어한다.

본 연구는 제주 연안에 서식하는 중형저서동물 군집의 특성과 계적적 변동을 알아보고자 수행되었다. 제주도 조간대 지역에서 20개의 조사지점을 선정하였으며, 2017년 4월부터 2019년 2월까지 총 8회의 조사를 수행하였다. 조사결과, 조사지점 당 중형저서동물의 밀도는 733~2,505 inds. 10 cm^-2였으며, 2017년 4월에 밀도가 가장 높았고 2019년 2월에 가장 낮았다. 모든 조사지점에서 Nematode가 우점하고 있는 것으로 나타났으며, copepod와 nauplius가 그 다음 우점 분류군으로 조사되었다. 생태계 건강성을 나타내는 Nematods/Copepods ratio (N/C ratio)는 2017년 4월에 가장 낮은 값인 0.02, 2019년 2월에 가장 높은 값인 87.40으로 산출되었으며, 이는 조사지점의 건강성이 악화되었음을 의미한다. Multi-Dimensional Scaling (MDS) 분석결과는 제주 연안의 중형저서동물 군집구조는 지역적 차이보다는 계절적 변동에 의해 더 크게 영향을 받고 있음을 나타냈다. 제주도의 중형저서동물 군집의 계절적 변동 특성을 보다 명확히 이해하기 위해서, 추가적인 군집조사와 환경 인자와의 상관관계 분석이 후속 연구로 필요할 것으로 판단된다.

경기도 도시대기측정망의 시간별 PM₁₀과 PM_2.5 농도에 대하여 측정소별로 상관성을 분석하여 측정소별 미세먼지 농도자료의 유사성을 파악해보았다. 미세먼지 경보제를 위해 사용되고 있는 기존의 권역구분을 그대로 이용했을 때, 동일한 권역 내의 측정소들은 PM₁₀의 경우 0.68, PM_2.5는 0.70 이상의 피어슨 상관계수 값을 보였으나, 일부 측정소는 타 권역과 높은 상관성(예, 0.80 이상)을 보여주고 있었다. 또한, 현재 구분하고 있는 권역은 주로 고농도 사례 횟수에 따른 군집분석 결과와 지리적 요인 등을 복합적으로 고려하여 결정된 것이므로, 미세먼지 관리를 위해서는 농도 특성에 따라 권역을 재분류할 필요성이 있다. 따라서 본 연구에서는 다차원척도법을 이용하여 미세먼지의 시간별 농도변화와 지역별 배출 기여율을 고려한 재범주화를 진행할 수 있었고, 이를 시각적으로 도시화할 수 있었다. 그 결과, PM₁₀은 5개의 권역으로 분류되고, PM_2.5는 4개의 권역으로 구분되었다.

Purposes: The purpose of this study was to identify the preferred types of the hospital reservation cancellation management to help reduce the reservation cancellations. Methodology: This study sampled 327 outpatients or their guardians who had reserved a university hospital and a general hospital located in the southwestern part of Seoul, and the responses from 300 of them were used for the final analysis. The subjects' preferences of reservation cancellation management types were analyzed in reference to their demographic variables. The timing and frequency of pre-notification preferred by the subjects were examined. A multidimensional scaling methods and correspondence analysis was used to identify preference for management methods of no-show and type of reservation guide. Findings: As a result, 77.3% of the respondents were perceived that the reservation cancellation was a habit. The most preferred method of managing the reservation cancellation would be refusal to refund the reservation deposit (61.7%), followed by payment for cancellation (16.0%), limit of future reservations (16.0%) and penalty (6.3%) in their order. 186 of the subjects (62.0%) preferred the texting for prevention of reservation cancellations, and 102 of the subjects (34.0%) preferred the phone calls. The preferred timing and frequency of the SMS were twice 3 days before, once a day before and three times 7 days before, while the preferred timing and frequency of phone call was once a day before. Practical Implications: The no-show rate can be improved by enhancing SMS pre-notification and by improving afterwards telephone counseling. For other factors, it needs to study on the service differentiation with the characteristics of each patient group.

The purpose of this study is to examine design preferences for the sales spaces of duty-free shops (DFSs) by conducting image evaluations. The results will help improve quality by influencing designs for the construction, extension or remodeling of these shops. An image measurement method, the semantic differential method, was used to measure cognitive structure using photos of shops. Photos were collected of the DFS at Jeju Island, as well as photos of brand stores designed by architects. Two sets of 16 photos (32 different photos in all) were selected according to photo classification standards and design concepts, both decided by reviewing previous studies and related materials. The evaluation and survey were done by two sets of subjects: sales employees, who have experience and special knowledge of the evaluation of sales space; and students majoring in architecture. To strengthen the evaluation results, I conducted a preliminary survey and a main survey, verifying and complementing findings. 116 surveys were conducted, of which 14 were of poor quality and rejected, leaving and 102 to be analyzed. The collected surveys were statistically analyzed, using SPSS 12.0 for Windows. Reliability, image profile, factor and multi-dimensional scaling analyses were conducted. As a result, image evaluation structure and characteristics were obtained for sales spaces of DFSs, confirming the difference between them and other spaces.

Forearm fractures in children are very common among all pediatric fractures. However, biomechanical investigations on the pediatric forearm are rather scarce, partially due to the complex anatomy, closely situated, interrelated structures, highly dynamic movement patterns, and lack of appropriate tools. The purpose of this study is to develop a computational tool for child forearm investigation and characterize the mechanical responses of a backward fall using the computational model. A three-dimensional 10-year-old child forearm finite element (FE) model, which includes the ulna, radius, carpal bones, metacarpals, phalanges, cartilages and ligaments, was developed. The high-quality hexahedral FE meshes were created using a multi-block approach to ensure computational accuracy. The material properties of the FE model were obtained by scaling reported adult experimental data. The design of computational experiments was performed to investigate material sensitivity and the effects of relevant parameters in backward fall. Numerical results provided a spectrum of child forearm responses with various effective masses and forearm angles. In addition, a conceptual L-shape wrist guard design was simulated and found to be able to reduce child distal radius fracture.
