Objectives: The purpose of this study was to examine the associations and paths among parenting behaviors, cyber delinquency, and moral sensitivity in adolescents to reduce and prevent cyber delinquency. Method: The data was collected by a survey for 270 students from a middle school and a high school in G city. The valid 262 cases were analyzed by frequency, descriptive analysis with SPSS 18.0 and tested by structural equation model by using AMOS 18.0 program. Results: Results showed that 1) 'control' among the parenting behaviors has positive effects on the cyber delinquency in adolescents, 2) 'intimacy and rationality' among the parenting behaviors has positive impacts on the moral sensitivity, 3) it shows that moral sensitivity has negative effects on the cyber delinquency in adolescents, and 4) bootstrapping test for indirect effect of moral sensitivity was verified significantly. We founded the full mediation of moral sensitivity and the path of 'intimacy and rationality' to cyber delinquency through moral sensitivity. Conclusions: The results implied 1) provision of the parent education and program for parents and newlyweds to learn positive parenting behaviors and 2) application of moral education to develop moral sensitivity of adolescents in schools and communities.

Spinning mechanism is generally used in coasting process on grass plates. Rebounding PR(Photo Resist) which leads to occur inferiority of coating process is caused by vibrational energy of whole coating system. In this study, the sensitivity analysis is performed to analyze and reduce vibrational terms in the spin coating system. The sensitivity analysis is bared on the numerical expression of this system. By the bond graph method. power flow of each system is represented by some basic bond graph elements. Any energy domain system is modeled using the unified elements. The modelled spin coater system is verified with power spectrum data measured by FFT analyzer. As the results of verifying model parameters and sensitivity analysis, principal factors causing vibration phenomenon are mentioned. A study on vibration method in the spin coating system is discussed.

The purpose of this study is to propose a model built on the theoretical foundation of ecological sensitivity applicable to group and coaching process for organization members in industry management environment. For this, I have looked into theoretical foundation basis-foundation required for the ecological sensitivity process based on ecological discourse, based on which I have proposed a process model. The ecological basis-foundation with regards to ecological sensitivity dealt with in this paper includes 1)Crisis awareness, 2)Acquisition of ecological unconsciousness, 3)Fostering green imagination and 4)Setting targets.

There is substantial evidence that insulin sensitivity can be enhanced through appropriate dietary management . In this study, insulin sensitivity was evaluated using and insulin suppression test. Male Sprague-Dawley rats, were caused to be in a diabetic condition by the injection of streptozotocin, and divided into four groups. They were fed one of the following diets for 2 weeks : (group 1) a high-carbohydrate(CHO) low-fat low-fiber diet, (group 2) a high CHO low-fat and high-fiber diet, (group 3) a low-CHO high-fat and low-fiber diet, and (group 4) a low-CHO low-fat diet groups (as comparison between group 1 and group 2 shows). In the low-CHO high-fat diet groups, dietary fiber tended to decrease plasma glucose levels at the end of the experiment, but not significantly (as comparison between group 3 and group 4 shows). The average steady state plasma glucose level in rats on the group 3 diet was the highest among all four groups(p<0.05), indicating the poorest insulin sensitivity . However, high fiber increased insulin sensitivity in rats on the low-CHO high-fat diets(as shows by a comparison between group 3 and group 4). On the other hand , the high-CHO low-fat enhanced insulin sensitivity in rats on the low fiber diet(group 1 and group 3). The degree of enhancement of insulin sensitivity depends on the combination of CHO, fat , and fiber in the diet. In conclusion, this study demonstrates that a low-CHO high-fat low -fiber diet may be deleterious to diabetic rats. In view of insulin sensitivity enhancement , dietary fiber level is irrelevant, as long as the diet has a high-CHO and low-fat level.

The current study was undertaken to determine the effects of the ratios of dietary fat to carbohydrate and energy restriction on insulin sensitivity in the growing rats. Male rats weighting 80-90g were fed experimental diets for two weeks. Rats were killed and epiddymal adipose tissue were removed and sliced. Explants of adipose tissues were incubated for 2 hours in KRB(Krebs-Ringer bicarbonate) buffer containing various concentrations of human insulin and [U-14C]glucose. Insulin sensitivity was determined as glucose conversion to total lipids (lipogenesis) during 2 hr incubation. Exp't I : Effects of Ratios of Fat to Carbohydrate on Insulin Sensitivity. Eighteen male rats were fed 3 diets for 2 weeks. Diet 1 was low fat-high carbohydrate (4% soybean oil and 66.5% cornstarch) ; diet 2, medium fat-medium sarbohydrate(12% soybean oil and 58.5% cornstarch) ; diet 3, high fat-low carbohydrate (20% soybean oil and 50.5% cornstarch). Insulin sensitivity was higher in the order of LF-HC, MF-HC and HF-LC diet groups (p<0.05), i.e, lipogenesis was higher at all insuline concentration in the explants from rats fed LF-HC diet. However, thers was no significant difference in body weight gain and epididymal adipose tissue weight among treatments. Exp't II ; Effects of Energy Restriction on Insulin Sensitivity. Twelve rats were grouped into ad libitum feeding and restricted feeding(70% of ad libitum). The experimental diet was medium fat-medium carbohydrat diet as used in the Exp't I. Restricted feeding group tended to show higher insulin sensitivity compared to ad libitum group. However, there was no statistical difference between two groups. As expected, body weight gain and epididymal adipose tissue were higher in the ad libitum group. In summary, the resutls of the current study showed that the epididymal adipose tissue taken from the rats fed low fat-high carbohydrate diet showed higher insulin sensitivity compared to those fed high fat-low carbohydrate, and that resticted feeding tended to elevate insulin sensitivity in these tissues.

민감도 해석은 어떤 설계 변수의 변화가 전체 시스템에 미치는 영향을 확인하기 위한 방법으로, 계산된 민감도는 구조개선 시 중요한 지표가 된다. 본 연구에서는 유한요소해석을 이용하여 설계 변수에 대한 민감도 도출 및 분석 방법과, 민감도 결과를 활용한 구조개선 방법을 제안하였다. 구조 개선이 필요한 실제 반도체 검사 장비를 이용하여 경량화를 위한 설계 변수를 선정하고 설계 변수에 대한 민감도를 유한요소법과 유한차분법을 활용하여 계산하였으며, 장비가 요구하는 과도응답(Transient Response)은 유지하면서도 무게 감소가 가능한 개선 방안을 제시하였다. 유한요소해석과 유한차분법을 이용한 민감도 분석 결과를 이용한다면 구조물의 설계 개선 시 원하는 응력 또는 변위는 만족하면서도 구조적으로 향상된 설계를 할 수 있고, 이는 반도체 검사 장비뿐만 아니라 다양한 분야에서 활용이 가능하다.

Objectives: The purpose of this study was to investigate the relationship between periodontal disease, number of remaining teeth with high-sensitivity C-Reactive protein in Korean adults aged 40 and older. Methods: The study used the Sixth Korea National Health and Nutrition Examination Survey (KNHANES VI-3), 2015. The study sample consisted of 3,883 aged 40 years or older who had completed the health survey and the health examination. Logistic regression analyses were performed to examine the odds ratios of high-sensitivity C-Reactive protein by periodontal disease and number of remaining teeth, adjusting for demographic characteristics, chronic diseases and oral health behavior-related variables. Results: When the demographic and chronic diseases were adjusted, the risk of high-sensitivity C-Reactive protein (hs-CRP) average 1.23 mg/L or higher was 1.36 times higher in patients with periodontal disease between the ages of 40 and 49, but it was not significant (OR=1.36; 95% CI=0.82-2.23). In addition, in the group of 0~23 remaining teeth aged 40~49 years, the risk of higher than the average 1.23 mg/L of high-sensitivity C-Reactive protein was 2.03 times higher (OR=2.03; 95% CI=1.10-3.74), and 1.49 times higher in 60~69 years (OR=1.07; 95% CI=1.04-2.76). Conclusions: This study found that periodontal disease and tooth loss in Korean adults aged 40 and older was significantly associated with high-sensitivity C-reactive protein.
