This study purports to empirically examine the potential effect of the level of social trust on their welfare consciousness level. Although previous studies in the field have focused on socio-economic or class-oriented variables, the accumulated results have shown that the effects were inconsistent at best in Korean context. In order to overcome the limits of theoretical assumptions from mainstream Marxists and institutionalists, this study suggests the relative autonomy of social consciousness and its independent effect on welfare consciousness. The analysis shows that both foundational variables, income levels and labor market participation, and the level of social trust have significant impacts upon the respondents' level of welfare consciousness.

The purpose of this study was to investigate the influence of dental hygienist images and career advice among high school teachers. A self-reported questionnaire was administered to 212 high school teachers in Gwangju, South Korea. The questionnaire contained subject's general characteristics, images of dental hygienists, and career advice. We performed an independent t-test, the Kruskal-Wallis test, Pearson's correlation coefficient, multiple regression analysis, and logistic regression analysis using the IBM SPSS ver. 21.0 software. Using a five-point scale, the average of all the dental hygienist images was 3.50, with personal images receiving the most positive rating at 3.83 and social images receiving the least positive rating at 2.86. The images of dental hygienists were significantly more positive in instances where the subjects recognized the dental hygienist or received treatment within one year. There were positive correlations among different kinds of images. Through multiple regression analysis, occupational images were associated with business and social images. Business images were associated with occupational and personal images. Personal images were associated with business images, especially in cases where the subjects recognized the dental hygienist. Social images were associated with occupational images, especially in cases where subjects received treatment within one year. Through logistic regression analysis, career advice was associated with social and occupational images. Therefore, our study provides suggestions on how to enhance positive recognition of social images of dental hygienists.

In the most cases of eigen value problems in the social sciences, the object matrix to analyze is real-valued symmetric matrix. And many cases of eigen value problems in this field needs 2-4 eigen pairs according to the magnitude of their absolute values. The methods to obtain eigen pairs by numerical computation using computer, we would face the problem of round off error because matrix computation needs a number of calculations. In this paper, an algorithm which make us to get some needed eigcn pairs according to the magnitude of their absolute values is designed. And in this algorithm, the power method is used to obtain some eigen pairs. This algorithm is expected to be effective by the reduction of the number of calculations.

최근 몇 년간 정보보호가 사회적 이슈로 자리 잡았다. 사회적 이슈라는 단어가 일반인들에게는 정보보호와 관련된 사건 사고로 이해될 수 있겠지만, 기업의 관점에서는 정보보호와 관련된 법률과 규제에 대한 대응의 다른 이름이기도 하다. 정보보호는 비즈니스 측면에서 예상치 못한 비용을 발생시킬 수 있으며, 소비자와 기업 간 분쟁의 원인이 되는 하나의 리스크가 된다. 이 리스크를 차단하거나 줄이기 위한 가장 효과적인 방법은 기업 스스로의 자발적인 노력이 전제되어야 한다. 그런 면에서 CJ인터넷 보안팀은 '자발적 노력'이라는 단어가 참 잘 어울리는 곳이다.

The cognition for corporate social responsibility of Chinese companies is negative because it increases cost and causes reduction of profit. But interest and execution for corporate social responsibility of Chinese firms is increasing consistently. Purpose of this study is to find effect of corporate social responsibility on firm value to Chinese enterprises. To achieve this purpose, we performed multiple regression method to 647 firms listed on the Shanghai Stock Exchange of China in 2011. Dependent variable is firm value and independent variable is degree of execution of corporate social responsibility to stakeholders. Conclusions of this study are as follows. First, execution of corporate social responsibility for employees, bondholders, government appeared to have a significant positive effect to firm value at 1% significance level. Second, execution of corporate social responsibility for customers appeared to have a significant negative effect to firm value at 1% significance level. Third, execution of corporate social responsibility for stockholders, suppliers appeared to have a weak positive effect on firm value, however these variables showed statistical insignificant.

The purpose of this study was to investigate the image and the awareness of dental hygienists in dental hygiene and non-dental hygiene students. The subjects in this study were 414 students who were in the three-year-course department of dental hygiene and in another four-year-course non-dental hygiene department in G college in the city of Gwangju. After a survey was conducted, the collected data were analyzed. The findings of the study were as follows: 1. As a result of general awareness about dental hygienists, the dental hygiene students knew 97.5% and non-dental hygiene students knew 80.6% about dental hygientist as a job. There were significant differences(p<0.001). In regard of awareness about status in medical law, medical technician was the highest in the dental hygiene students(52.8%), and medical assistant was the highest in the non-dental hygiene students(48.8%) 2. As a result of awareness about the main tasks of dental hygienists X-ray and scaling were the highest in the dental hygiene students(42.3%), and treatment assistance was the highest in the non-dental hygiene students(32.9%). 3. In regard to awareness about image of dental hygienists, both groups were the highest in professionalism and were the lowest in negative image. All variable were differences statistically between dental hygiene and non-dental hygiene students(p<0.05).

The present study was conducted to investigate the effect of nutrition education program on anthropometric values and boichemical index in obese children who live in Gumi city. The subjects were 16 obese boys, 20 obese girls with obesity index over 130 and 36 of their parents. The nutrition education was carried out by the professional personnel such as doctors, professors, and dietitians. The children were provided with well-balanced lunch meals and had 40min-lectures on the reasonable weight management, 40 min-games and also had regular exercises (stretching, swimming) for 90 mins everyday during 2weeks of the program. The parents had 90 min-lectures on childhood obesity, diet therapy, behavior modification, and exercise for 6times. After the program, obesity index, BMI, % body fat were significantly decreased (p < 0.05) in boys and obese index, BMI, % body fat and WHR were significantly decreased (p < 0.05) in girls. Blood cholesterol and TG levels of girls were significantly decreased (p < 0.05). These findings show that the well-designed nutrition education program for obese children can be an effective approach to help them to improve their anthropometric values and biochemical index.

본 연구는 기후변화에 따른 강우현상의 극한화에 대응한 도시치수규모 설정 방안에 대한 연구이다. 발생가능한 모든 강우상태를 강우지속시간과 강우량 매트릭스로 구성하고 모든 강우상태에 대한 침수규모를 사전에 산정한 후 도시침수 상태를 추정하는 2변수(강우량, 강우지속시간) 회귀식을 개발하였다. 치수규모 결정을 위해서 지금까지 사용해 오던 "발생빈도" 기준의 극치통계의 개념적, 공학적 의미를 재해석하여 물리적으로 의미가 있는 "침수 특성치" 기준으로 대전환하자는 것이다. 기술적으로 가능해졌기 때문이다. 도시유역의 침수를 정량적(침수심, 침수면적)으로 모의할 수 있는 방법을 제시하기 위한 침수상태의 기준이 될 침수특성치로는 관로첨두유출량, 최대침수면적, 침수총량, 평균침수심, 특정지점의 최대침수심, 특정지점의 침수지속시간 등 6가지를 선정하였다. 우리나라에서 발생가능한 모든 강우상태에 대한 침수 발생 가능성을 점검하여 침수특성치를 분석하고 해당 유역의 "물리적/사회적 특성"을 고려한 "사회적 합의"에 의해 "감당할 수 있는 피해의 정도"에 맞춘 도시유역 치수계획규모를 설정하는 방안을 확립하는 것이다. 또 결과로 구해지는 다음과 같은 형태의 유역별 침수특성치 산정식(2변수 회귀식)을 각 유역별로 구해 놓으면 기상예보(강우지속시간-강우량)에 따라 유역의 침수 특성치를 쉽게 추정하여 사전에 확립해둔 방재대책을 시행할 수 있게 한다.

This study associates with socio-economic status in a slice section area of Chicago metropolitan to get spatial patterns of urban windows. GSIS(Geo-spatial Information System) has been monitored with several statistic methods, and geo-spatial map presentations. From the grouping analysis, the result displays that most suburban town have high income values, such as Elmhurst, Melrose Park, North Lake(Income ranges between $25,000${\sim}$30,000 : 1980 Sensus data). The factors produced form both analyses of SAS and BMDP are socio-ethnic, economic, hispanic, black, life expectancy, and multiple car ownership. In the study area the socio-ethnic factor is striking, and is composed of nine out of the fourteen varialbles. Geo-spatial 3-D mapping represents a socio-economic configuration of the study area. The high income value areas are Elmhurst and North Lack, and a spot between Belmont Ave. and the Lake Shore. Economic configuration is a vital importance of socio-economic activities in the urban areas. In the study area a minimum average income level is about $4,364 and maximun is $30,311.
