Objectives: CRATAEGII FRUCTUS(山査) is known as the substance which decreases concentration of sarum lipid. The purpose of this study is to investigate the effects of CRATAEGII FRUCTUS(山査) on decreasing concentration of sarum lipid which are triglyceride, total cholesterol, HDL-cholesterol, LDL-cholesterol in rat high cholesterol diet inducede hyperlipide rats. Methods: Sprague-Dawley rats were divided into 3 groups, Normal group(supplied enough water and feeds only. Normal Group), high fat diet administered group(AIN-76 high fat diet #100496 used beef tallow for 4 weeks, Control Group) and CRATAEGII FRUCTUS(山査) administered group(AIN-76 high fat diet #100496 used beef tallow and CRATAEGII FRUCTUS(山査) extracts 85.0mg/200g 1time/day for 4 weeks. SS Group). Rats were sacrificed and concentration of triglyceride, total cholesterol, HDL-cholesterol, LDL-cholesterol were measured in rat's sarum lipid Results: There was no significant difference in the level of waight between each experimental group(F=0.243, p=0.787, ANOVA test), Concentration of triglyceride has no significant difference in each group(F=0.210, p=0.813, ANOVA test). There was significant increase of total cholesterol in the Control group compared to those of Normal but there was no significant difference in the SS group compared to the Control group(F=5.237, p=0.0l9, ANOVA test). There was a significant increase of HDL-cholesterol in the SS group compared to the Control group and decrease in Control group compared Normal group(F= 11.437, p=0.001, ANDYA test). Concentration of LDL -cholesterol was significantly different in each group(F= 16.377, p=0.0001, ANDYA test). It was significantly increased in the Control group compared with the Normal group and it has no difference in the SS group compared to the control group. TBARS values(Thiobarbituric Acid Reactive Substances) were significantly different in each group(F=5.242, p=0.0019, ANDYA test). It was significantly increased in the Control group compared with the Normal group and significantly decreased in SS group compared with the Control group. Conclusions: According to the above results, it is considered that CRATAEGII FRUCTUS(山査) is effective in decreaseing concentration of sarum lipid in high cholesterol diet induced hyperlipidemic rats.

In addition to optimistic bias which can be a biased phenomenon in perceived susceptibility, including illusion of control which is a distorted phenomenon, the current study attempted to demonstrate the influential relationship between these two important variables and COVID 19 personal preventive behaviors and social distancing practice. Conducting Survey utilizing online pannel from Macromill Embrain, the present study performed regression analysis, setting personal preventive behavioral variables such as mask wearing, hand washing, using hand sanitizer as independent variable, and analyzed how these independent variables influence control illusion and optimistic bias. As a result, COVID 19 personal preventive behavior didn't have direct effect on optimistic bias and control illusion except for hand washing. Finding, also, showed that control illusion affected optimistic bias, and the relation between these variables was different depending on demographic variable such as gender and age.

Objctives: This study purposed to examine the intention to participate in the preventive program of depression of Internet user and to offer the baseline data for development of mental health promotion program. Methods: The internet survey was performed using a self-reported questionnaire on intention to participate in the preventive program of depression, depressive symptom(with Zung's SDS) and so forth from 1,000 internet user (aged $13{\sim}49$ years) via two web sites at Feb($1st{\sim}10th$), 2006. We analyzed the intention to participate in preventive program of depression and the factors related with that intention by depressive level. Results: In the normal group, the intention to participate in a preventive program of depression was influenced significantly by counselling experience(s) on depression(p<.001), and perceived control(p<.001) over the barriers to participation in the preventive program of depression, and marginally by gender. In the depressive group, the smoking habit revealed marginal effect(p=.051) and perceived control over the barriers to participation in the preventive program of depression influenced on that intention significantly(p<.001). Conclusion: Among internet users, especially the solutions of barriers to participate in the preventive program of depression is more important at the intervention program for prevention of depression. In the normal group, we need to consider the use of messages tailored by counselling experience(s) on depression. Some intervention program dealing with two subjects, smoking cessation and prevention of depression concurrently, will be appropriate for the depressive group.

Based on the stability margin provided by the EEAC, the unstable contingencies can be classified into sets according to their unstable modes. This two-part paper develops a globally optimal algorithm for transient stability control to coordinate preventive actions and emergency actions. In the first part, an algorithm is proposed for a set of contingencies having identical unstable modes. Instead of iterations between discrete emergency actions and continuous preventive actions, the algorithm straightforwardly searches for a globally optimal solution. The procedure includes assessing a set of insufficient emergency schemes identified by the EEAC; calculating the related preventive actions needed for stabilizing the system; and selecting the scheme with the minimum overall costs. Simulations on a Chinese power system highlight its excellent performance. The positive results obtained are explained by analogizing settlements for 0-1 knapsack problems using the multi-points greedy algorithm.

Objectives: Given the increase in osteoporosis among health volunteers and the effect of health literacy on the adoption of nutritional preventive behaviors, this study aimed to determine the effects of an educational intervention on health literacy and the adoption of nutritional preventive behaviors related to osteoporosis among health volunteers. Methods: This was a quasi-experimental, interventional study of health volunteers conducted in 2020. In this study, 140 subjects (70 in both intervention and control groups) were selected using the random multi-stage sampling method. An educational intervention was conducted using the Telegram application, and educational messages were sent to the health volunteers in the intervention group across 6 sessions. Data were collected via a demographic questionnaire, the Health Literacy for Iranian Adults survey, and a nutritional performance questionnaire, which were completed before and 3 months after the intervention. The data were collected and analyzed using SPSS version 23. Results: Before the intervention, there were no significant differences in the mean scores for health literacy variables and the adoption of nutritional preventive behaviors between the intervention and control groups (p>0.05). After the intervention, there was a significant change in the mean scores for health literacy and the adoption of preventive behaviors in the intervention group (p<0.05) as opposed to the control group. Conclusions: Interventions aimed at increasing health literacy are effective for promoting the adoption of preventive and healthy nutritional behaviors related to osteoporosis.

The purpose of this study is to investigate attitude factor related to hearing conservation and to find attitude affecting the preventive behavior for hearing conservation. The research method used in this study was self-administered questionnaire. Samples of the study were composed of 353 workers exposed noise selected randomly in 10 ship-building manufacturing companies. Authors extracted following 9 factors related hearing conservation from 26 attitude propositions prepared from previous study results and health belief model; (1) general perceived susceptibility, (2) relative perceived susceptibility compared with colleagues, (3) concern to the personal protective devices, (4) perceived severity and concern to the hearing capacity, (5) concern to the hearing and noise assessment, (6) concern to the control noise and hearing conservation, (7) group pressure and reason of wearing protective devices, (8) apathy of hearing loss from noise, (9) knowledge about hearing conservation. Attitude factors affecting the preventive health behavior were general perceived susceptibility, concern to the noise control and hearing conservation, and concern to the personal protective devices in the case of wearing personal protective devices. But in the case of avoiding noise exposure as preventive health behavior, perceived severity and concern to the hearing capacity was a significant attitude factor with knowledge about hearing conservation.
