This paper attempts to explore the impact of technological regulation on technological innovation and performance of Small and Medium Enterprises(SMEs) by analysing a survey data of 286 Korean SMEs. The 3-step mediated regression analysis results reveal that the perceived regulatory burden is negatively associated with SMEs' R&D investment and innovation of product and process. Moreover, the level of regulatory burden may affect the objective and subjective performance of SMEs. The results suggest that regulatory policies for reducing regulatory burden need to be designed and implemented in order to enhance technological innovation and performance of SMEs.

This paper was trying to investigate the periodontal health recognition and self oral hygiene behaviors and figure out that relationship. The results having analyzed 592 questionnaires returned patient who had visited the dental clinic which is selected randomly were following. There were relationships between the periodontal health recognition and self oral hygiene behaviors. Self oral hygiene behaviors were significantly high when, women did than men did, education level, subjective oral health status, and periodontal health recognition about managements were higher and periodontal health recognitions about treatment were lower. It was the periodontal health recognition that was influential the most in the independent variables. Therefore, knowledge related to the periodontal health should be educated to the patients visiting the dental clinic, and the patients should receive helps to perform self oral hygiene behaviors by inducing the transition of attitude to periodontal health.

As material perspective that stresses absolute income has limitations in explaining socioeconomic gradients in health, research on the relationship between an individual's subjective socioeconomic status(SSS) and health has emerged in recent years. Although previous research has been conducted mostly on adults, late school-aged children, who frequently evaluate themselves using social comparisons, are likely to subjectively perceive their socioeconomic status and be affected by their perception. Accordingly, this study examined the relationship between late school-aged children's SSS and their physical health, and its underlying path based on a psychosocial perspective. For this purpose, data from the first year survey of the Seoul Education and Health Welfare Panel (2014), which consisted of responses from 394 children ($4^{th}$ graders in elementary school) and their parents, were analyzed utilizing structural equation modeling. The results showed an indirect but significant relationship between late school-aged children's SSS and their physical health, via stress, self-efficacy, and health behaviors, which are mediating variables grounded on a psychosocial perspective. No direct relationship was found between late school-aged children's SSS and physical health. Based on these findings, we suggested several implications to improving children's health, including efforts to prevent adverse effects of low SSS on physical health through psychosocial factors.

This study aimed to demonstrate the effect of feedback type on users' subjective responses in a voice user interface. Feedback type is classified depend on information characteristic it involves; verification feedback and elaboration feedback. Error type is categorized as recognition error and performance error. Users' subjective assessment about system, feedback acceptance, and intention to use were measured as dependent variables. The results of experiment showed that feedback type has impacts on the subjective assessment(likeability, habitability, system response accuracy) of VUI, feedback acceptance, and intention to use. the results also demonstrated an interaction effect of feedback type and error type on the feedback acceptance. It leads to the conclusion that VUI should be designed with the elaboration feedback about error situation.

This study was conducted by using the Q research method, one of the qualitative analysis methods, in order to approach consumers' perceptions of processed meat food in an essential and in-depth approach. To this end, Q-sort, which goes through the task of distributing responses by setting P samples by creating a question-and-answer table of positive and negative, was analyzed by using the PC QUANL program and analyzing the Q factor. As a result of the analysis, it was divided into three single types. Type 1 (N= 10) : Preferred types of processed meat food, Type 2 (N= 7) : Types of Pursuing Functionality of Processed Meat Food, Type 3 (N= 4) : The name of the factor was set as the non-preferred type of processed meat food. Each type has different characteristics, and the subjective perception of each factor detected through this analysis can be used as various basic research data in the future, and for the purpose of the study, the perceptions of consumers who use processed meat foods were classified and classified by type. It is to suggest future improvement directions by checking the characteristics of the variables.

The aim of this study was to investigate the association between self-rated oral health, self-rated health, and quality of life (QOL) among older population from the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII-1, 2016). Data of 1,866 older adults (Mean age 69.5 years) were analyzed with hierarchical logistic regression analyses with IBM SPSS 23.0. Over 87.7% of the subjects rated their oral health as fair or poor. Women and less educated participants more likely to report their perceived oral health as poor (p<.05). Older participants who rated their general health positively were more likely to rate their oral health as good (F=19.04, p<.001). Elders who had bad perceived health (OR: 2.86, 95% CI: 1.5~5.5), had carries in permanent teeth (OR: 2.68, 95% CI: 1.67~4.32) and anxiety or depression (OR: 1.45, 95% CI: 1.42~2.57) had negative oral health perception after controlling for covariates. In conclusion, perceived oral health and QOL were associated with each other in Korean older adults. Therefore, it is recommended to approach holistic strategy for improve health and quality of life in the elderly population.

This study was scale for subjective health-recognition related general factor, health habits and management, cancer recognition and provision. Methods : The subjects were elderly who voluntarily participated in the survey. Results : The Health recognition people 50.7% answered 'Normal'. The health condition should have obstructed a daily life, said that cognition cannot be good health recognition. The health control method was bad or normal group manages with the medical supply (foodstuffs inclusion) then again, the recognition good group was answered that did not tobacco and drink alcohol or prohibit do it. For ten years from now the health recognition about cancer occurrence possibility that the health recognition good group was rare possibility 42.7%, bad group was 52.0% and normal group was 47.6%. Conclusions : In health promotion priorities of elderly differed by gender and subjective health status. The regular exercise and health-related habit do as a favor the possibility of living is healthy.

In this study, we examined at what level young people perceive their level of life and the overall degree of happiness in their lives, and empirically analyzed the factors affecting them through multiple regression and ordered logit models. As a result of the analysis, young people were more aware of the degree of overall happiness than their perception of their lives. It has been confirmed that the factors affecting the young generation's perception of the level of life and the degree of happiness are different and different factors are working on each group. In addition, it has been found that the subjective factors of psychological and emotional characteristics have a greater influence than the objective factors of social and demographic characteristics at the level of awareness of life and happiness level. However, in the case of the youth group, it was found that objective factors such as job satisfaction are the determinants that have the greatest influence on life awareness and happiness. The tendency to paradoxically respond to the current level of happiness due to despair of the future has been found to be seen in some subgroups(middle income plus working group) rather than in the whole youth generation.

일반적으로 강우-유출모형은 lumped model과 distributed model로 크게 구분될 수 있으며, 우리나라에서는 이중 비교적 부족한 자료를 이용하여도 개략적 모의가 가능한 전자를 널리 사용하고 있다. 본 연구에서는 이러한 모형들의 매개변수를 보정하는 방법에 관해 연구하였다. 일반적으로 모형의 보정 방법에는 크게 시행오차에 의한 수동보정(manual calibration) 방법과 최적화 기법에 의한 자동보정(automatic calibration) 방법으로 나눌 수 있다. 수동보정 방법은 모형 수행결과를 수문곡선의 시각적 비교에 의해 관측치와 비교하여 모형 운영자의 주관적인 판단하에 조정하는 기법이며, 자동보정 방법은 최적화 기법을 이용8하여 특정한 산정기준(estimation criteria)을 최대 또는 최소화시켜 모형의 매개변수를 결정하는 방법이다. 이러한 최적화기법은 일반적으로 직접탐색법과 경사법으로 구분할 수 있다. 경사법은 수렴속도가 빠르지만 편미분에 의해 방향을 찾아가는 방법으로 편도함수가 필요하므로 수문모형에는 적용하기가 힘들므로 적합하지 않다. 그러나, 보다 많은 컴퓨터 수행시간을 필요로 하는 직접탐색법의 경우 수렴속도는 느리지만, 편도함수를 필요치 않으므로 수문모형의 최적화 기법으로 적합하다고 할 수 있다. 직접탐색법에는 simplex-search 법, 패턴인식(pattern-search)법, rotating-direction 법, brent 법 등이 있으며, 본 연구에서는 직접탐색법의 일종인 패턴인식(pattern -search)법을 이용하여 매개변수 최적화 과정을 모의하였다. 이러한 매개변수 보정모형을 구성한 후 이를 가장 보편적으로 사용되고 있는 유출모형인 각종 단위도법들을 결합하는 모형을 구성하였다. 또한 구성된 모형을 시범유역에 적용하여 나온 결과를 HEC-1에서 적용되고 있는 단일변량 증감법과 같은 최적화 기법을 이용한 결과와 비교·분석을 실시하였다. 본 모형을 활용하여 강우-유출 모형의 매개변수를 지속적으로 산정하고 일반화할 경우 임의의 유역의 수문기상학적 특성에 부합한 매개변수를 정량화 시킬 수 있었다.

The purpose of this study is to examine that basic pension entitlement affects the subjective well-being(SWB) of the elderly. For controlling unobserved heterogeneity, we used fixed effects model for longitudinal data. The data used for this study is KLoSA from 2006 to 2016. The research results are as follows. SWB of non-basic pensioners was higher than for basic pension beneficiaries. Second, when the demographic variables were controlled, SWB of the basic pension recipients was higher then that of non-beneficiaries. Third, the factors affecting SWB were economic satisfaction, marital status, family financial support, employment status, subjective health status, daily life restrictions, gender, and age. Fourth, the effect of basic pension on SWB was positive at the lowest income quartile. The results of this study shows that the basic pension system has a positive effect on the SWB of elderly despite the low benefit level. Therefore, it is necessary to expand the basic pension system to solve poverty problems and improve the quality of life for the aged. Also, various aspects of social support for the low-income vulnerable elderly are needed. Lastly, It was suggested that the benefit level of the basic pension should be raised to have a substantial effect on the low-income class, which is a key policy subject.
