자동차에서 실내음질은 구매결정 요소들 중의 하나로 그 중요성이 점차 증가하고 있다. 따라서 다양한 운전조건에서 운전자가 기대하는 실내음질의 기대 수준을 충족시켜야 한다. 소비자는 운전경험과 습관에 따라 기대하는 음질에 차이가 있고 소리에 대한 표현방식도 모호하기 때문에 이러한 주관적 특성을 하나의 통일된 표현으로 정의 하기가 어렵다. 그러나 지난 이십여 년 동안의 음질개발과 차량 실내소음 주관평가의 통계처리로 통일된 표현을 할 수 있었다. 나아가 심리음향학 및 신호처리기술의 발달과 꾸준한 음질연구결과로 소리특성을 객관적으로 나타내는 소리의 시각화가 가능하였으며, 운전자가 인식하는 주관평가와의 상관관계를 높여 차량의 대표적인 음질인자로 정량화하여 음질목표를 설정할 수 있었다. 실내소음의 구성은 엔진 투과음, 흡배기 소음, 바람 소음, 도로 기인 소음 등으로 다양하므로 소음원에 따라 음의 균형을 맞추어 조화로운 음질개발을 하는 것이 중요했다. 또한 차량 판매되는 지역에 따라 선호음이 상이하여 지역별 실내음질의 차별화가 필요했다. 궁극적으로는 운전자의 감성품질을 만족할 수 있도록 음을 제어하여 브랜드 사운드를 개발하고 있다. 이러한 실내음질을 달성하기 위한 방법으로 소음원과 전달경로에 대해 기여도를 분석하고, 경로를 구성하는 시스템 별로 세분화하여 시스템 목표를 설정하였다. 시스템 개발에 중요한 인자로 차량의 동강성 및 흡차음 성능을 들 수 있다. 특히 디젤차량의 비중이 큰 유럽업체의 차량의 동강성 및 흡차음 개발 능력은 높게 평가되고 있다. 이에 유럽의 부품전문회사가 가지고 있는 해석과 시험적인 개발 방법을 통하여 전달계 특성을 만족하기 위한 시스템의 동강성 및 흡차음 특성을 개발하고 있다. 차량음질 튜닝의 중요한 기법 중 하나로 흡배기 개발을 추진하고 있다. 친환경자동차인 하이브리드차량, 전기차량 및 연료전지차량의 경우 전기구동부품에서 발생하는 각종 이음 발생을 최소화 했다. 보행자를 보호하고 운전의 즐거움을 향상하기 위한 가상사운드 개발을 진행하고 있다. 회사 수익성 향상을 위한 원가절감 및 구조 경량화에 따른 음질악화와 연비 향상 및 배기가스 규제 강화로 고성능 고출력 엔진탑재에 따른 음질악화 요인을 극복해야 했다. 운전자의 청감은 차량의 운전성에 따라서도 크게 영향을 받게 되므로 엔진제어와 변속기제어를 통해 음질과 운전성이 조화를 이룰 수 있도록 개발하고 있다. 향후, 소음원에 따른 시스템 최적화 개발, 운전성과 음질 연계 개발과 친환경차량의 가상사운드 개발 등이 자동차 음질 개발의 중요한 이슈로 생각한다.

This study investigates the effect of site characteristics in fashion social commerce and SNS subjective norms on the attitude of consumers towards social commerce and their purchase intentions for fashion products. In addition, this study tests consumer responses through a comparison of a group purchase mall versus a private mall. Respondents are limited to consumers aged 20 to 39 who have recently purchased fashion products through social commerce over the last month. Four hundred samples were used for the final analysis. Descriptive statistics, Cronbach's alphas, a confirmatory factor analysis, and a structural equation modeling analysis were conducted. The results are as follows. Product value, convenience and SNS subjective norms without trust significantly influenced the consumer attitude towards social commerce, and the attitude of consumers positively influenced the purchase intentions of fashion products. In the group purchase mall, only convenience affected the attitude of consumers; in the private mall, product value, convenience and SNS subjective norm had an effect on the attitude of consumers. In addition, the SNS subjective norm positively influenced purchase intentions directly as well as indirectly. Social commerce ought to offer product value and create a simple and convenient design to raise the purchase intentions of fashion products; in addition, they should use SNS functions to inform consumers of social commerce. It is imperative to implement different marketing strategies according to social commerce type.

This study was conducted to investigate the effects of oral health awareness and oral health behavior on cardiocerebrovascular prevention behavior in a cardiocerebrovascular diseases risk group and provide basic data for a nursing intervention program for the group. Data were collected from 131 people in the risk group of cardiocerebrovascular diseases living in J Province in February and March of 2018. The obtained data were analyzed using descriptive statistics, t-tests, Pearson's correlation, and stepwise multiple regression analysis. The results revealed that preventive acts were positively correlated with subjective oral health state (r=0.261, p=0.003), importance of oral health (r=0.250, p=0.004), and practice of oral health (r=0.303, p<0.001). Moreover, acts to prevent cardiocerebrovascular disease were influenced by oral health (${\beta}=0.29$, p<0.001), age (${\beta}=0.27$, p=0.001), and subjective oral health state (${\beta}=0.24$, p=0.003). Specifically, scores of preventive acts for cardiocerebrovascular diseases increased with higher degree of oral health behavior, older age, and better subjective oral health state. These variables had an explanatory power of 19.3%. The results of this study imply a need to prepare measures to enhance the oral health level of the risk group of cardiocerebrovascular diseases and conduct ongoing follow-up studies of the perception, attitude, and behavior of individuals toward oral health, as well as the state of oral health.

Prior to the start of the general oral examination, this study was performed using the theory of planned behavior to provide data that would help not only increase intention of industrial workers' dental care utilization after their dental examination, but develop the follow-up oral health programs. As the first research group, 608 workers were selected from the 1016 workers while excluding both 53 workers who were currently undergoing dental treatment and 355 workers who had an opportunity to visit the dental clinic over the previous six months. Among the general characteristics that would influence the 608 workers' intention to utilize the dental clinic within one (1) month, their financial state showed that the higher their financial abundance level, the stronger their intention to visit the dental clinic(p<0.01). It was shown that the attitude toward the dental care utilization related behavior and subjective norm except the perceived behavioral control among the TPB variables had a significant effect on their intention(p<0.01). Among TPB variables, attitude toward the dental care utilization and subjective norm except the perceived behavioral control, were significant correlation with behavioral intention(p<0.01). The structure model's R-square of the attitude toward the behavior, subjective norm and perceived behavioral control having and effect on the intention accounted for 21%. In order to encourage the workers to have positive thoughts about the attitude toward their dental care utilization and subjective norm, therefore, it is required to perform the continued oral health programs, in addi1ion to oral health experts' regular education.

This study examines the relative usefulness of the TPB and Extended TPB with the addition of the "Battery" variable to participants in marine sports experiences. The characteristics of behavioral theories (attitude, subjective norms, perceived behavioral control, and revisit intention) were compared. A total of 420 questionnaires were distributed and surveyed using the convenience sampling method to the general public who participated in the marine sports experience in S city in 2019. Finally, 385 copies of valid samples were extracted, except for the questionnaire. The following analyzes were performed using SPSS 21.0 and AMOS 21.0. Frequency analysis, confirmatory factor analysis, concept reliability, AVE value, Cronbach's α correlation analysis, hierarchical regression analysis, and independent sample t-test were performed. First, in the TPB, three predictors were found to have a positive effect on revisit intention. Attitudes, subjective norms, and prior knowledge, except for behavioral control, were found to have a positive effect. Second, the explanatory power to explain the return intention was 51.8% (3.3% more than plan behavior theory, p = .000). It can be seen that when prior knowledge is added as a new variable, it is an important factor in explaining intention to return. Third, prior knowledge variables were classified into high and low groups to compare the characteristics of the extended planning behavior theory. The results of the analysis showed that the group with higher prior knowledge had a higher mean value for the constituent variables of the extended planning behavior theory.

The selection rate of tree burials (TB) is still low in spite of increasing concerns about TB and government's efforts to increase TB participation. It is necessary to understand the factors affecting TB selection. This study investigated the relationship between major variables (attitude: ATT; subjective norm: SN; perceived behavioral control: PBC) of Ajzen's theory of planned behavior (TPB), additional variable (custom: CUST), and intention to select TB by using structural equation modelling (SEM). Samples were selected from Gwang-ju citizens using proportionate stratified sampling (PST) by region during September of 2011. Four hundred and twelve responses were used for data analysis. The model showed fair goodness of fit. All four variables (ATT, SN, PBC, CUST) influenced intention to select TB. The four variables explained 53.0% of intention to select TB. SN(${\beta}$=0.459) was the most predictive variable on the intention, followed by ATT(${\beta}$=0.247), PBC(${\beta}$=0.152), and CUST(${\beta}$=0.102) in decreasing order. The results were discussed and some suggestions to increase the intention of tree burial selection were made.

The purpose of this study was that HPV prevention education based on the planned behavioral theory was designed to provide college students with HPV vaccine knowledge, cervical cancer knowledge, attitude toward HPV vaccination, subjective norms for HPV vaccination, perceived behavioral control for HPV vaccination, and HPV vaccination. This is an experimental study to confirm the effect on the intention to vaccinate and the behavior of HPV vaccination. The subjects were arbitrarily expressed as 32 subjects in the experimental group and 34 subjects in the control group. The collected data were analyzed by descriptive statistics, t-test, χ²-test, Fisher's exact test and repeated Measures ANOVA. As a result, the experimental group participating in HPV prevention education was compared to the control group who did not participate in HPV vaccine knowledge (t=5.66, p<.001), cervical cancer knowledge (t=4.13, p<.001), attitude (t=2.24, p=) .032 ), subjective norm (t=2.83, p=.008), perceived behavioral control (t=2.65, p=.013), and intention (t=3.91, p<.001) were significantly different. After 4 weeks of HPV prevention education intervention, there was a significant difference in the interaction between group and time course of HPV vaccination intention (F=6.95, p=.002). Therefore, it was confirmed that HPV prevention education is an educational program that can be applied to college students.
