This study analyzed the lower body type of women aged 20 to 30 to understand their respective characteristics. The research method was restricted to the use of direct measurements data and 3D measurements data of the Sixth Size Korea. Factor analysis, cluster analysis, ANOVA, Duncan's test, discriminant analysis, t-test, and ${\chi}^2$-test were performed for the statistical analysis of the data using SPSS Win 20.0 program. The results of this study are as follows. Lower body type based on 3D measurements were classified into 3 types (obese lower body, long lower body, and small lower body). Lower body type based on direct measurements were classified into 3 types (obese lower body, thick and long lower body, and small lower body). Lower body type based on the direct measurement of sitting pose were classified into 3 types (obese lower body, long and thin lower body, and short lower body). The age differences in the lower body types could be analyzed by an evaluation of the 3D simulation of the lower body.

Objective: This study was performed to verify how DISC behavior patterns affect the major satisfaction and professionalism of dental hygiene students and provide basic data for dental hygiene students to have increased major satisfaction and maximize their strength by understanding their DISC behavior pattern. As a result, the following conclusion was obtained. Methods: The data was collected From November 1, 2018 to November 14, 2018, 218 dental hygiene students. Data was collected using self-reported questionnaires. Statistical analysis was performed with IBM SPSS ver. 21.0. Mean (standard deviation) and one-way ANOVA & pearson correlation were performed. Results: The most frequent DISC behavior patterns of dental hygiene students was steadiness types (49.0%) followed by influence types (34.5%), conscientiousness types (9.0%), and dominance types (7.5%). There were no significant difference in professionalism and major satisfaction according to DISC behavior patterns in dental hygiene students. There was a correlation between major satisfaction and professionalism of dental hygiene students. Conclusion: In conclusion, in order for dental hygiene students to establish positive professionalism through increased major satisfaction, it is necessary to make various efforts such as providing consultation and education that corresponds to each student's DISC behavior patterns. These efforts will provide the students career vision and encourage them to improve their academic achievement and find employment that fits their vocational aptitude.

This aim of the study is to investigate the plan and elevation types of existing way stations built in the early 20th century Korea, focused on Choong-ang, Donghae-nambu, and Kyung-jeon line of the railroad tracklines. The plans and elevations are drawn up and analyzed based on literature data and aerial photographs through the survey. These way stations are classified into various types by room layout and front elevation. The basic plan types are composed of waiting room, station service room, and administration. The station service room has a train operation room in the projecting part of corner. This room has windows on every side to see in and out of train. There are the enlarged, extended waiting room types, and linear types in the other plan types. The waiting room is lied on the right side, and has a gable roof in elevation. The elevation types are classified with side and centralized, and so on by the placement and shape of gable roofs. The basic elevation types have gable roofs in sides lied on the waiting room, and these types are transformed into centralized types by extension of waiting room The others are the linear types without gable roofs and the unusual roof types in appearance.

최근 메모리 기술의 급격한 발전으로 개발되고 있는 다양한 종류의 메모리는 데이터 관리 시스템에서 처리 속도 향상을 위해 활용되고 있다. 특히 NAND 플래시 메모리는 전원이 차단되어도 데이터를 유지할 수 있는 비휘발성 특징이 있으므로 메모리 기반 저장장치의 데이터 저장용 주요 미디어로 활용되고 있다. 그러나 최근 연구되고 있는 메모리 기반 저장장치는 NAND 플래시 메모리뿐만 아니라 MRAM과 PRAM 등 다양한 종류의 메모리로 구성되어 있고 추가로 새로운 특성이 있는 다양한 종류의 메모리가 개발되고 있다. 따라서 특성이 서로 다른 이종의 메모리들로 구성된 저장 시스템에서 미디어의 데이터 처리 성능과 효율 향상을 위한 메모리 관리 기술의 연구가 필요하다. 본 논문에서는 데이터 관리를 위해 다양한 메모리로 구성된 저장장치에서 데이터를 효율적으로 관리하기 위한 메모리 사상 기법을 제안한다. 제안하는 아이디어는 서로 다른 이종 메모리를 하나의 사상 테이블을 활용하여 관리하는 방법이다. 이 방법은 데이터의 주소 체계를 통일할 수 있고 데이터 티어링(tiering)을 위해 서로 다른 메모리에 분할 저장된 데이터의 탐색 비용을 감소시킬 수 있다.

This study classified and analyzed the upper body types of 7-13 years old elementary school boys, using 3D data from the 6th Size Korea. The results of this study are as follows. Seven factors were extracted from the factorial analysis as an independent factor for a cluster analysis. The cluster analysis generated four body types. Type 1 has large ratio of front and back depth as well as circumference, with a front protrusion. In Type 2, the vertical value of upper torso is longer than average; in addition, its flatness is the largest and produces a thin body type. Type 3 has a smaller flatness in the bust, waist, abdomen and hip than other types, while also having the largest BMI. Type 4 is characterized by a greater shoulder angle than other types and its other factors are close to average. As a result of the logistic regression analysis, the prediction model used eight variables to generate and its accuracy is 88.679%. The classification of upper body types from this study can be used as basic data to improve patternmaking for each body type. The generated prediction model is also expected to be used as a method to help classify upper body types using the eight variables.

여러 분야에서 이상탐지의 중요성이 강조됨에 따라, 다양한 데이터 유형과 이상치 유형에 대한 이상탐지 알고리즘이 개발되고 있다. 하지만 이상탐지 알고리즘의 성능은 주로 공개 데이터 세트에 대해 측정될 뿐 특정 유형의 이상치에서 나타나는 각 알고리즘의 성능은 확인되지 않고 있으므로, 분석 상황에 맞는 적절한 이상탐지 알고리즘 선택에 어려움이 있다. 이에 본 논문에서는 이상치의 유형과 다양한 데이터 속성을 먼저 파악하여, 이를 기반으로 적절한 이상탐지 알고리즘 선택에 도움을 줄 수 있는 방안을 제시하고자 한다. 구체적으로 본 연구에서는 지역, 전역, 종속성, 그리고 군집화의 총 4가지 이상치 유형에 대해 이상탐지 알고리즘의 성능을 비교하고, 추가 분석을 통해 라벨 수준, 데이터 개수, 그리고 차원 수가 성능에 미치는 영향을 확인한다. 실험 결과 이상치 유형에 따라 가장 우수한 성능을 나타내는 알고리즘이 다르게 나타나며, 이상치 유형에 대한 정보가 없는 경우에도 안정적인 성능을 보여주는 알고리즘을 확인했다. 또한 비지도 학습 기반 이상탐지 알고리즘의 성능이 지도 학습 및 준지도 학습 알고리즘의 성능보다 낮게 나타나는 유형을 확인하였다. 마지막으로 데이터 개수가 상대적으로 적거나 많을 때 대부분 알고리즘들의 성능이 이상치 유형에 더 강하게 영향을 받으며, 상대적으로 고차원일 경우 지역, 전역 이상치에서는 우수한 성능을 보였지만 군집화 이상치 유형에서 낮은 성능을 나타냄을 확인하였다.

This study was conducted to review data utilization plans and suggest solutions based on the need for tools that can objectively diagnose problems in rural areas. The study extracted items through prior research and was carried out as a process of reviewing data capable of constructing spatial data. The results performed in the above manner are as follows. First, prior research and expert surveys were conducted to select diagnostic items to derive details of a total of three items that should be considered for rural space plans such as regional revitalization and regeneration using regional characteristics such as environment, society, and culture. Second, as a result of listing data available for regional diagnosis, 6 types of environment, 15 types of society, and 18 types of culture were selected out of a total of 529. Finally, it was suggested to establish a national standard spatial unit by grasping the limitations of public data such as omission of spatial data and accuracy. This study is significant in that it presented implications for data utilization as well as selection of items for rural diagnosis and reviewed data utilization based on rural specialized districts of "The Act on Support for Restructuring and Regeneration of Rural Spaces" to be implemented in 2024. This is considered to be valuable as a study for sustainable rural diagnosis if processes such as spatial data construction and weight setting are carried out in the future.

In wireless network, we propose a predictive location update scheme which considers mobile user's(MU's) mobility patterns. MU's mobility patterns can be found from a movement history data. The prediction accuracy and model complexity depend on the degree of application of history data. The more data we use, the more accurate the prediction is. As a result, the location management cost is reduced, but complexity of the model increases. In this paper, we classify MU's mobility patterns into four types. For each type, we find the respective optimal number of application of history data, and predictive location area by using the simulation. The optimal numbers of four types are shown to be different. When we use more than three application of history data, the simulation time and data storage are shown to increase very steeply.
