Ojectives: This study performed to analyze health promotion factors related to subjective stress level among first-year students of university. Methods: To examine the association with subjective stress level and health promotion factors, health survey was conducted with 3,892 students who were first-year students in an university by self-reported questionnaire from February 26 to March 10, 2015 in an university. Multiple regression analysis performed to identify the difference of health promotion factors by subjective stress level. Results: 1,015 students (26.1%) were on high stress level and 2,110 students (54.2%) were in healthy status. The 10.8% of them was obesity group and the 40% was alcohol use disorder group. The 8.2% had experienced depression in the last 1 year. In multiple regression models, it remained significantly the difference of subjective stress level by sex, subjective health status, sleep hours in a day, eating frequency of fruit and vegetable in a day, depression experience and suicidal thought in the last 1 year(p<0.05, p<0.01). On the other hand, it was not significant the difference by age, BMI, alcohol use disorder, eating breakfast, regular exercise and current smoking. Conclusions: To improve health promotion of first-year students of university, it should provide the intensive mental health program to women on campuses.

Purpose: To investigate the behavioural factors of the health promotion for caregivers based on a socio-ecological model. Methods: This study was a cross-sectional descriptive study using a self administered questionnaire. The survey was conducted in 219 people chosen through convenient sampling between September and December 2008. The collected information included general characteristics, individual, interpersonal, community, policy level. Results: For the statistical analysis, the t-test was used for the health promotion according to the general characteristics and to each level of the socio-ecological model, by assessing the high and low values and dividing them into mean points. The influence elicited by different health promotion factors was determined using the hierarchical multiple regression. At the individual level, the factors influencing health promotion in caregivers included perceived seriousness, perceived benefits, and self efficacy. Social support was important at interpersonal level, and the use of community resource was relevant for the community level. We found no statistically significant factors relating to the policy level. Conclusions: In conclusion, the socio-ecological models seems appropriate for explaining health promotion and its associated factors in caregivers. We suggest that, for caregivers, strategies should be developed for their social support and to offer information about how to use community resources in relation with factors relating to the individual level.

This study was conducted to provide information which will be useful for managing the forest trails effectively. To investigate users' attitudes toward the forest trail construction and use, a questionnaire survey was employed in the Jirisan Dulegil. As the results, most of the respondents perceived that the Jirisan Dulegil have positive impact economically and socio-culturally on community growth. Contrastively, a negative perception existed in the environmental aspect. The users' satisfaction level regarding the Jirisan Dulegil appear to be positive. Users' satisfaction level regarding use services provided in community boundary was evaluated relatively lower. In this point of view, trail use service system provided in the community should be reconsidered for effective forest trail management.

This study investigated vocabulary learning strategies used by EFL middle school learners in Korea and examined the relationship between the middle school learners' vocabulary learning strategy (VLS) use and their vocabulary proficiency level. One hundred and forty-one students in a public middle school participated in the study and the data for this study were collected from a vocabulary learning strategy questionnaire and a vocabulary proficiency test. Based on the result of the vocabulary proficiency test, the participants were divided into three proficiency groups: high-, mid- and low- level proficiency groups. The overall findings of the study revealed that the participants used cognitive strategies most frequently and social strategies least frequently. The most frequently used individual strategies were 'using a bilingual dictionary,' 'studying the sound of a word' and 'practicing words through verbal repetition.' The least frequently used ones were 'interacting with native speakers' and 'studying or practicing the meaning of a word in a group.' The research results also showed that the vocabulary proficiency level has a significant influence on the vocabulary strategy use. The more proficient learners used vocabulary learning strategies more actively. More specifically, the high proficiency level group used metacognitive strategies the most. The middle and low proficiency groups used cognitive strategies the most. It is suggested that language teachers should facilitate the vocabulary learning process by helping learners develop appropriate strategies.

The use of dental implants has become a mainstay of rehabilitative and restorative dentistry. With an impressive clinical success rate, there remain a few minor clinical issues with the use of implants such as peri-implant mucositis and peri-implantitis. The use of laser technology with implants has a fascinating breadth of applications, beginning from their precision manufacturing to clinical uses for surgical site preparation, reducing pain and inflammation, and promoting osseointegration and tissue regeneration. This latter aspect is the focus of this review, which outlines various studies of implants and laser therapy in animal models. The use of low level light therapy or photobiomodulation has demonstrated its efficacy in these studies. Besides more research studies to understand its molecular mechanisms, significant efforts are needed to standardize the clinical dosing and delivery protocols for laser therapy to ensure the maximal efficacy and safety of this potent clinical tool for photobiomodulation.

This study suggests the organization-level standard(model and process) for quality evaluation of information systems(IS) in non-use organizations despite international standards(ISO/IEC 9126 and ISO/IEC 14598) and national standards(KS X 9126 and KS X 14598) related to quality evaluation of IS. The standard in this study is composed of quality evaluation processes, a quality model, and quality metrics. The weights of the attributes and the sub-attributes in the quality model were calculated by an analytic hierarchy process(AHP). The minimum level and the target level of each metrics were determined by brainstorming of the committee. Furthermore, the case study for the investigation of the applicability and the usability of the suggested organizational standard in the real IS development project was performed. For gaining significant benefits of the standard, both the diffusion and the experience accumulation by its continuous use are needed.

With the development of films, games and animation industry, analysis and reuse of human motion capture data become more and more important. Human motion segmentation, which divides a long motion sequence into different types of fragments, is a key part of mocap-based techniques. However, most of the segmentation methods only take into account low-level physical information (motion characteristics) or high-level data information (statistical characteristics) of motion data. They cannot use the data information fully. In this paper, we propose an unsupervised framework using both low-level physical information and high-level data information of human motion data to solve the human segmentation problem. First, we introduce the algorithm of CFSFDP and optimize it to carry out initial segmentation and obtain a good result quickly. Second, we use the ACA method to perform optimized segmentation for improving the result of segmentation. The experiments demonstrate that our framework has an excellent performance.

This study investigates the factors that facilitate or hinder people to use mobile payment, especially drawing upon the theoretical perspectives on individual's privacy protection motivation and perceived market condition. Survey data (n = 200) were collected through a web-based platform and used to test a theoretical model. The results show that one's privacy protection power is formed by various individual and technological factors (i.e., perceived data exposure, self-efficacy, and response efficacy), and in turn it determines his/her intention to use mobile payment. Moreover, the relationship between privacy protection power and mobile payment use is conditional on the perceived market control by the service provider - with a perception of the high level of provider's market control, one uses mobile payment regardless of his/her privacy protection power, while under the low level of provider's market control, the decision depends on the degree of privacy protection power. The findings would help our understanding of why some people are more susceptible to mobile payment and others are not.

A new communication revolution such as social networking service (SNS) has been transforming the way of interaction between people in both of individual level and organizational level. Recently many people have switched to closed type SNS such as Naver Band and Kakao group due to the several reasons. The purpose of this study is to investigate the usage motivation and satisfaction of SNS based on use and gratifications perspectives. Based on prior studies on use and gratifications of Internet-related media and SNS, information motivation, relationship motivation, pleasure/entertainment motivation, self-expression motivation, work motivation were identified as usage motivation of SNS. This empirical study explores how these motivations vary between open type SNS(facebook and twitter) and closed type SNS(band and kakao group). This study contributes to provide the base of activation strategies and practical implications for companies using SNS as a marketing tool.
