This study analyzes the effect of corporate social responsibility (CSR) activity on investors' heterogeneous beliefs. The hypothesis of this study is based on the conflicting effects of CSR activities on firm value and earning's quality. Investors' heterogeneous beliefs used in the empirical analysis of this study are trading volume, and CSR activity is measured by the KEJI Index (Korea Economic Justice Institute Index). This study performs an empirical analysis using regression analysis including control variables. CSR activities are found to have a positive relationship with trading volume. This is consistent regardless of the low and high accounting information (earning's quality). It can be interpreted that Korea's CSR activity acts as an incentive to increase investors' heterogeneous beliefs about target companies. In other words, it implies that the investor judges CSR activities negatively when evaluating firm value. This study could have a policy implication in that it analyzes how CSR activities affect investors' decision-making. In other words, this study analyzed CSR activities from the perspective of shareholders. Therefore, this study is expected to provide useful information for policymaking by regulatory agencies. In particular, its contribution is to presents data that CSR activities can be a negative factor in evaluating firm values.

Purpose: This study was performed to identify nursing students' fall prevention activities, health beliefs of falling and factors associated with fall prevention activities among nursing students. Methods: 149 nursing students from a university completed self-administered questionnaires including participants' characteristics, fall prevention activities, and health belief of falling. Hierarchical multiple regression analysis was used to determine significant independent factors of fall prevention activities. Results: The score for fall prevention activities was $62.40{\pm}9.78$, which was relatively high. The regression model had an adjusted $R^2$ of .16, which indicated that perceived susceptibility was a factor affecting fall prevention activities of nursing students. Conclusion: To increase perceived susceptibility, repetitive fall prevention education including various examples of falls could help nursing students to promote fall prevention activities. Nursing faculty should develop contents to increase recognition of obligation and responsibility regarding fall prevention in curriculum for nursing students.

The purpose of this study is to grasp the relationship between the amount of physical activities at work perceived by workers and their health promotion behaviors. To achieve such a purpose. this survey was conducted on 476 Workers who work for 3 food product work-sites located in Keong-in area by means of questionnaire from June 15 to July 14 . 1998. Collected data were statistically analyzed by SPSS/WlN. The significant results were obtained as follows. 1. The average scores of the amount of physical activities at work and health promotion behavior were 3.18 and 2.84 respectively; the former was slightly higher than moderate score 2.5 and the latter was almost the same as it. It can be interpreted that workers perceive their physical activities at work are heavier than their daily activities, which seems to make their health promotion behaviors still inactivated. 2. The amount of physical activities at work, it was were greater revealed that the more activities workers do after work. the more they walk and the more exercises they do. It implies that the voluntary practice of good health habit at leisure can be greatly contributed to the activation of more productive activity at work. 3. The amount of health promotion behaviors was larger as workers do more physical activities at work and have lower PIBW(Percent Ideal Body Weight). It means that the voluntary practice of good health habit is closely related to the degree of obesity and their positive attitude toward their work. Average PIBW was 106.71; most of the workers are distributed within the standard range in their weight. So we can presume that most of them are not seriously conscious of weight maintenance in their daily lives. Therefore it is desirable that health promotion program for workers should be developed toward connecting their physical activities at work with those in their daily lives much more. Physical activities, health promotion behaviors

Purpose: This study was aimed to describe Helicopter Emergency Medical Services (HEMS) and analyze the flight nurses' activities in HEMS. Methods: Data were collected retrospectively from the air transportation reports that contained data of 168 patients transported by aircraft to G University medical center in Incheon since June, 2012 to March, 2013. Data were analyzed using descriptive statistics, and Mann-Whitney U test. Results: Average distance of flights was 44.0 km, duration of field treatment took 13.6 minutes, and duration of a flight from scene to hospital was 14.5 minutes. Nursing activities were categorized into 12 direct nursing activities and 5 nursing management activities, and a total number of 7806 nursing activities were occurred in HEMS. The most frequently performed nursing activity was measurement and monitoring (27.9%) followed by medication (11.5%) and respiratory management (8.7%). The most frequent nursing management were information management (11.0%). Nursing activities performed were significantly different depending on the patient's level of consciousness, cause of illness, crew configuration, and type of transportation. Conclusion: This study described HEMS nursing activities performed by flight nurses. Difference in nursing activities according to patient characteristics, crew configuration and type of transportation requires flight nurses to be prepared through educational programs to improve nursing activities and nursing management during air transportation.

Aloe vera L.(Aloe barbadensis Miller) has been used for many centuries for various medical, cosmetic and neutraceutical purposes. The gel of A. vera was reported to exert numerous biological activities including wound healing, immunomodulatory, anti-cancer, anti-inflammatory, anti-bacterial, anti-viral, anti-diabetic, and anti-psoriasis activities. Acemannan, found predominantly in the inner leaf gel of A. vera, has been identified as the main active ingredient exerting diverse biological activities. In this review, we summarized the recent findings on the immunomodulatory activities of acemannan. Studies that used purified acemannan demonstrate that acemannan exerts immune-stimulating, anti-cancer, anti-viral, and hematopoiesis-increasing activities. In addition, it is being clear that most of these activities of acemannan are mediated primarily by activating professional antigen presenting cells such as macrophages and dendritic cells.

The effect of dietary capsaicin (8-methyl-N-vanillyl-6-nonenamide, CAP) on drug-metabolizing enzyme activities was investigated in mice. Male ICR mice were divided into 4 groups and fed diets containing 0, 5, 20, 100 ppm CAP for 4 seeks. Hepatic drug-metabolizing enzyme activities and serum alanine aminotransferase and aspartate transaminease activities were measured. There was no difference in hepatic alanine aminotransferse and aspartate transaminase activities among the groups. Hepatic microsomal cytochrome P450 in CAP fed groups, but p-nitrophenol hydroxylase and the cytosolic acitivity of glutathione S-transferase activities were decreased in the dietary CAP supplemetned groups compared to the control. These results suggest that the dietary CAP at a low dose differentially modulates drug-metabolizing enzyme acitvities without causing hepatic toxicity.

The anti-oxidant activities of fucosterol isolated from the marine algae Pelvetia siliquosa were investigated. Fucosterol exhibited a significant decrease in serum transaminase activities elevated by hepatic damage induced by $CCl_4$-intoxication in rats. Fucosterol inhibited the sGOT and sGPT activities by 25.57 and 63.16%, respectively. Fucosterol showed the increase in the anti-oxidant enzymes such as hepatic cytosolic superoxide dismutase (SOD), catalase and glutathione peroxidase (GSH-px) activities by 33.89, 21.56 and 39.24%, respectively, in $CCl_4$-intoxicated rats. These results suggest that fucosterol possess not only the anti-oxidant, but also the hepatoprotective activities in rats.
