Purpose: This study aims to compare the health behaviors and mental health of adolescents from multicultural and non-multicultural families, and to determine the effect of multicultural families on adolescents' health behaviors and mental health. Methods: The study employed a cross-sectional design, utilizing data from the Korea Youth Risk Behaviour Web-based Survey 2020 and 2021. The sample comprised 9,828 multicultural adolescents and 13,389 non-multicultural adolescents. Results: Adolescents from multicultural families showed significant differences in their experiences with alcohol (x2=9.55) and substance use (x2=11.37), as well as suicidal ideation (x2=4.57) and suicidal attempts (x2=34.19), compared to their non-multicultural peers. Logistic regression analysis revealed that adolescents from multicultural families had a 1.19 times higher rate of recent alcohol experience, a 1.14 times higher rate of stress, and a 1.55 times higher rate of suicidal attempts. However, the rates of smoking and alcohol use were 0.80 times and 0.75 times lower, respectively, among adolescents from multicultural families compared to their non-multicultural peers. Conclusion: The findings suggest that health promotion programs are needed to help adolescents from multicultural families adapt socially, cultivate preventive health behaviors, and improve their mental health. These interventions should take a multifaceted approach that encourages family participation in the programs.

본 논문은 고속화된 망 환경의 변화와 다양화된 사용자의 요구를 충족시키기 위하여 설계된 HGTP(High-speed Group Transport Protocol)의 구현 및 성능 평가에 관한 것으로, 구현은 SUN Spare10의 IP/ethernet 환경에서 C-언어를 이용하여 사용자 영역에서 이루어졌다. 성능 평가는 SUN Spare10 워크스테이션 6대를 이용하여 시뮬레이션이 아닌 실제 망 환경에서 전송율 제어, 흐름 제어 및 데이타 패킷의 크기 등을 파라메터로 하여 HGTP 자체 성능에 대한 평가와 기존에 가장 널리 사용되고 있는 트랜스포트 계층의 프로토콜인 TCP와의 성능 비교를 통하여 HGTP의 효율성을 제시하였다. In this paper, we introduce our implementation and performance analysis of the HGTP(High-speed Group Transport Protocol) which is designed for changes of high-speed network environment and satisfaction of various user requests. We implement HGTP(High-speed Group Transport Protocol) on IP/Ethernet of SUN SpareStation using C-language in user space. We estimate performance of HGTP not by simulation, but by measurement with various parameters of rate control and flow control, and with variation of data packet size in real world and present the efficiency of HGTP by comparison with TCP which is widely used as transport protocol.

본 논문은 기존 트랜스포트 계층 프로토콜들의 단점을 극복하고, 고속망을 하부 구조로 갖는 환경에서 사용자의 고속 전송에 대한 요구와 다양한 분산 처리 응용을 위한 요구를 트랜스포트 계층에서 수용할 수 있는 HGTP(High-speed Group Transport Protocol)의 설계에 관한 사항을 각각의 전송 형태별로 기술하였다. 또한 기존 고속 트랜스포트 계층 프로토콜에서 제공하는 그룹 통신 기능인 멀티캐스트와의 기능적 비교를 통하여 고속망 환경에서 분산 처리 응용을 위한 통신 처리 시스템 구축시 HGTP를 트랜스포트 계층 프로토콜로 이용했을 경우의 효율성을 기술하였다. This paper describes each communication type of HGTP(High-speed Group Transport Protocol) which overcomes weak points of conventional transport protocols and satisfies requirements of high-speed transmission of users and of various distributed processing applications in transport layer under high-speed network environment. Furthermore, we describe the efficiency of using HGTP as transport protocol when we construct communication system for distributed processing application under high-speed network environment, through the functional comparision with multicast, the group communication facility of conventional high-speed transport protocols.

The purpose of this study is to identify users' preferences for attributes based on the degree of host-related information provision on shared accommodation platforms. Shared accommodation transactions are cooperative consumption based on trust, and trust issues form the basis of transactions. Therefore, as the importance of information increases in the construction of this trust, it is necessary to identify the preference for providing host information, one of the subjects of the shared accommodation platform. To accomplish the purpose of this study, choice experiment (CE) was used. The advantage of this methodology is that it can derive the marginal willingness to pay (MWTP) for each attribute, which quantitatively identifies the degree of preference of attributes. An online survey was conducted through Amazon Mechanical Turk (MTurtk), and a total of 261 copies were used in the analysis. Study results have shown that ‘host communication’, ‘host history’, and ‘sort review’ attributes have a positive impact on respondents' preferences, while accommodation costs have a negative impact. Among the attributes, host communication's marginal payment was the highest at $67.72 (76,646 KRW), followed by sort review at $40.30 (45,612 KRW) and host history at $27.50 (31,125 KRW).
