The purpose of this study was to identify the impact of generation on the traditional food culture of Uzbekistan-Koreans. The generation of Uzbekistan-Koreans was divided into two groups i.e., the second and third generation. The second generation suffered from the compulsory emigration during 1930s because of the minority racial breakup policy by the Soviet Russia. The third generation was born after the compulsory emigration and the economic condition was much better for them. In terms of identifying traditional food culture, generation was an important factor because each generation had different social environments and different life styles. Data were collected from 634 Koreans living in Uzbekistan and analyzed by chi-square and correlation analysis. The results of this study revealed that the impact of generation was an important factor regarding the traditional food culture. Chi-square analysis showed that factors related to making a menu, food priority, and consideration of the person preparing the food were likely to vary depending on the generation. Also, reasons for preferring traditional food and preparing foods for family events as well as national holidays were different between the second and the third generation. The second generation preferred traditional food because of flavor, while the third generation preferred traditional food because of nutrition. For family events and national holidays such as New Year's Day, the second generation was more likely to prepare traditional foods than the third generation. The correlation analysis indicated that the relationship between preference and intake frequency of traditional foods was positively related, and the degree of correlation was higher for the second than the third generation. Similarities and differences between generations were discussed, and implications for food and nutrition specialists and food marketers were provided.

This study investigated power generation of photovoltaic equipment at detached houses. The study estimated monthly mean generation according to maintenance conditions that included module cleaning, inspection into generation, cleaning of module and photovoltaic generation. At analysis upon generation, households with periodical module cleaning and inspection into generation, clean module and good generation conditions had high generation. 20-years of PV equipment life varied much depending upon maintenance conditions. Users should keep module clean and inspect generation regularly and put PV equipment at the place with good solar radiation.

The current bra market and the purchasing behavior of women of the MZ generation in Korea are reviewed in this study. Therefore, basic data for bra product planning for women of the MZ generation are presented by investigating the wearing status and satisfaction. Through online surveys, 272 questionnaires were obtained and were analyzed through frequency analysis, cross-analysis, t-test, and variance analysis. Generation M and Generation Z share digital culture, but, due to age differences, they are compared by generation. There was, however, little significant difference between these groups. In addition, there was no significant difference between groups when factoring for the time of wearing, place of purchase, and material of bras. However, there were big differences between groups depending on whether bras had wires, lace, and their size, especially in body correction items. According to the results, it is pointless to target each generation when making a bra. Also, the young generation consumers are more interested in functionality than in the design compared to 10 years ago. It will improve consumer satisfaction if two different types of bras are produced; one that corrects the body and one that fits well even if the body is less corrected.

본 논문은 지금까지의 소셜미디어 분석과 분석보고서 생성의 세 가지 문제점을 해결하기 위해서 소셜 빅데이터 마이닝에 기반한 이슈분석보고서 자동 생성 시스템을 제안한다. 세 가지 문제점은 분석의 고립성, 전문가의 주관성과 고비용에 기인한 정보의 폐쇄성이다. 시스템은 자연언어 질의분석, 이슈분석, 소셜 빅데이터 분석, 소셜 빅데이터 상관성분석과 자동 보고서 생성으로 구성된다. 생성된 보고서의 유용성을 평가하기 위해, 본 논문에서는 리커트척도를 사용하였고, 빅데이터 분석 전문가 2명이 평가하였다. 평가결과는 리커트 척도 평가에서 보고서의 품질이 비교적 유용하고 신뢰할 수 있는 것으로 평가되었다. 보고서 생성의 저비용, 소셜 빅데이터의 상관성 분석과 소셜 빅데이터 분석의 객관성 때문에, 제안된 시스템이 소셜 빅데이터 분석의 대중화를 선도할 것으로 기대된다.

In this study, an analysis was conducted to analyze the structural stability of the piezoelectric power generation module and to determine the optimal burying hole interval for concrete, the installation site of the power generation module. A piezoelectric element refers to a functional ceramic having a piezoelectric direct effect that converts mechanical energy into electrical energy and a piezoelectric reverse effect. In the analysis of the piezoelectric power generation module, the load condition was applied with about 16 tons and a total of 10 wheels in consideration of the container trailer. The purpose was to evaluate the stability of major components of the piezoelectric power generation module through finite element analysis. In order to determine the optimal burying location of the concrete ground for burying the piezoelectric power generation module, the stability of the ground structure according to the distance of the holes was determined. As a result of the analysis, the maximum stress of the piezoelectric power generation module was generated in the support spring, showing a stress of about 276.7 MPa. It was found that the spacing of holes for embedding the piezoelectric power generation module should be set to a minimum of 100 mm or more.

This paper describes an automatic finite element(FE) mesh generation for three-dimensional structures consisting of free-form surfaces. This mesh generation process consists of three subprocesses: (a) definition of geometric model, i.e. analysis model, (b) generation of nodes, and (c) generation of elements. One of commercial solid modelers is employed for three-dimensional solid and shell structures. Node is generated if its distance from existing node points is similar to the node spacing function at the point. The node spacing function is well controlled by the fuzzy knowledge processing. The Delaunay method is introduced as a basic tool for element generation. Automatic generation of FE meshes for three-dimensional solid and shell structures holds great benefits for analyses. Practical performances of the present system are demonstrated through several mesh generations for three-dimensional complex geometry.

In Korea, the next generation high-speed train, whose target is maximum speed of 400km/h and operating speed of 370km/h, has been developed since 2007. In this paper, the safety of the next generation high-speed train is compared UIC 518OR under the malfunctioning situation of the suspension system. The bogie of the next generation high-speed train has two suspensions. Two different vehicle models of the next generation high-speed train are created by using VAMPIRE and ADAMS/Rail, which are specialized to design railway vehicle. And Those models are showed same dynamic properties. First of all, the sensitivity analysis of ModelCenter is performed using model of VAMPIRE. One suspension element which has significant effects on the safety are selected by result of the sensitivity analysis. And then, the dynamic analysis when the suspension element is broken is performed using ADAMS/Rail. The 30km track between Pungsegyo and Biryong tunnel in Gyeongbu High-speed Line was used at the dynamic analysis. The estimated value is found by using the normal method of UIC 518OR. The estimated values on the normal/fault state and the limit values of UIC 518OR are compared. Finally, the safety of the next generation high-speed train is verified.

In this paper, we present a perspective of the next generation mobile communication services and its characteristics. As a preliminary research work on the next generation mobile communications and services, we exploit the next generation mobile services [1]. We define the next generation mobile services as strata of services consisting of three different service levels, the service areas, the service functionalities, and the service technologies. We derive these service levels by means of the scenario based analysis. Finally, we propose a conceptual network architecture that can support the next generation mobile services by placing network functions and service elements within the network.
