Feed intake, egg weight, rate of lay and shell quality characteristics were measured in an Australian tinted egg laying strain from 31-42 weeks of age, housed at $30^{\circ}C$ and provided drinking water at 5, 10, 17 and $30^{\circ}C$. In a second experiment a European brown egg laying strain (59-66 weeks of age) housed at $30^{\circ}C$ were provided drinking water at 5, 10, 15 and $30^{\circ}C$. Brown egg layers given cool drinking water (5, 10 and $15^{\circ}C$) consumed more (p<0.05) feed and produced significantly (p<0.05) thicker and heavier shells than hens given drinking water at ambient temperature ($30^{\circ}C$). However the tinted egg layers given chilled drinking water only consumed more (p<0.05) feed and produced thicker (p<0.05) and heavier (p<0.05) shells when consuming drinking water at $5^{\circ}C$. As the tinted egg layers acclimatised to the environmental temperature there was a decline in the influence of cool drinking water on feed intake and shell quality. For brown egg layers, however, cool drinking water resulted in an improvement (p<0.05) in feed intake and shell quality over the entire period birds were provided cool water. These studies suggest that there is potential for using cool drinking water to improve feed intake and shell quality of hens housed under hot conditions. The combination of high ambient temperature and high drinking water temperature, a common occurrence in Australian layer sheds, should be avoided.

Despite provision of drinking water as the most common method of occupational heat stress prevention, there remains confusion in hydration messaging to workers. During work site interactions in a hot and humid climate, workers commonly report being informed to consume tepid fluids to accelerate rehydration. When questioned on the evidence supporting such advice, workers typically cite that fluid absorption is delayed by ingestion of chilled beverages. Presumably, delayed absorption would be a product of fluid delivery from the gut to the intestines, otherwise known as gastric emptying. Regulation of gastric emptying is multifactorial, with gastric volume and beverage energy density the primary factors. If gastric emptying is temperature dependent, the impact of cooling is modest in both magnitude and duration (${\leq}5$ minutes) due to the warming of fluids upon ingestion, particularly where workers have elevated core temperature. Given that chilled beverages are most preferred by workers, and result in greater consumption than warm fluids during and following physical activity, the resultant increased consumption of chilled fluids would promote gastric emptying through superior gastric volume. Hence, advising workers to avoid cool/cold fluids during rehydration appears to be a misinterpretation of the research. More appropriate messaging to workers would include the thermal benefits of cool/cold fluid consumption in hot and humid conditions, thereby promoting autonomy to trial chilled beverages and determine personal preference. In doing so, temperature-based palatability would be maximized and increase the likelihood of workers maintaining or restoring hydration status during and after their work shift.

This study was designed to investigate development points for automatic ice maker which met consumer's demand. Basic data about using ices in Korean's dietary life, were collected from Seoul and Kyunggi-do residences and analyzed by SPSS program. The results were as follows; 93.7% of respondents had 3 major domestic brands' refrigerator and 41.4% of them had medium-large capacity(400-519L). 65% of respondents had a refrigerator that was purchased less than five years. 15.5% of respondents had one more refrigerator. Among of them, major refrigerator was located in kitchen(67.7%) and minor was in kitchen(29.8%) and in veranda or multi-purpose room(26.3%). 66.2% of respondents always prepared ices in ice container, and 85% of them used ice only in summer. Boiling water with barley or corn was used as drinking water (45.6%) and boiled or purified tap water was used to make ice (38.6%) commonly. In cooking, ice was used especially in cold soup with cucumber and seaweed(89.9%), ice-tea or ice-coffee(81%), and fruit punch(64%). The next commonly using ice was adding in alcoholic beverage such as whiskey(57.4%), in Koreans traditional drink(Misugaru) (45.2%) and juice. The purpose of using ice was to cool in soft drink (58.6%), to cool in cooking food(19.9%), to eat ice itself(14.0%), and to enjoy more fantastic taste and mood(3.8%). In whiskey, the purpose of using ices was to control alcoholic content (52.9%). There was no significant difference between sex in the purpose of using ice, but there was significant differences between age(p＜0.05). Seasonal variations in using ice, there were significant differences according to sex, age, roles in family, amount of preparation of ice, socio-economic level and brand and capacity of refrigerator in respondent's home.

The purpose of this study was to determine the effects of beverage temperature and composition on weight retention and fluid balance upon voluntary drinking following exercise induced-dehydration. Eight men who were not acclimated to heat participated in four randomly ordered testing sessions. In each session, the subjects ran on a treadmill in a chamber maintained at $37^{\circ}C$ without being supplied fluids until 2% body weight reduction was reached. After termination of exercise, they recovered for 90 min under ambient air conditions and received one of the following four test beverages: $10^{\circ}C$ water (10W), $10^{\circ}C$ sports drink (10S), $26^{\circ}C$ water (26W), and $26^{\circ}C$ sports drink (26S). They consumed the beverages ad libitum. The volume of beverage consumed and body weight were measured at 30, 60, and 90 min post-recovery. Blood samples were taken before and immediately after exercise as well as at the end of recovery in order to measure plasma parameters and electrolyte concentrations. We found that mean body weight decreased by 1.8-2.0% following exercise. No differences in mean arterial pressure, plasma volume, plasma osmolality, and blood electrolytes were observed among the conditions. Total beverage volumes consumed were $1,164{\pm}388$, $1,505{\pm}614$, $948{\pm}297$, and $1,239{\pm}401$ ml for 10W, 10S, 26W, and 26S respectively ($P$ > 0.05). Weight retention at the end of recovery from dehydration was highest in 10S ($1.3{\pm}0.7kg$) compared to 10W ($0.4{\pm}0.5kg$), 26W ($0.4{\pm}0.4kg$), and ($0.6{\pm}0.4kg$) ($P$ < 0.005). Based on these results, carbohydrate/electrolyte-containing beverages at cool temperature were the most favorable for consumption and weight retention compared to plain water and moderate temperature beverages.

Recently the use demand for national parks has been rapidly increased due to the change of leisure patterns in Korea. The intensive use of national parks, however, can cause serious management problems both in resource conservation and in visitor satisfaction. In order to prepare the effective management plan for the sustainable use of national parks, it is essential to evaluate the visitor satisfaction. The purpose of this study is to provide important information for the management strategies for Namsan and Tohamsan national parks in Kyongju. Importance-performance analysis (IPA) was adopted to analyze the visitor expectation and satisfaction. The questionnaire survey was performed to the 420 visitors of the three sites (Namsan Sam-reung, Namsam Yong-jang, and Tohamsan) that are the most popular areas in Kyongju national park. The IPA for the 18 satisfaction items shows that all the values for importance are higher than those for performance in the three sites. This results indicates that visitors' satisfactions for the 18 items are lower than their expectations. The IP matrix reveals that the management effort should be concentrated on the educational opportunities for nature and culture in Yong-jang, on the convenient access to park in Sam-reung. and on the availability of cool drinking water in Tohamsan. Based on the results, several suggestions for the management strategies were summarized for the three sites in conclusion.
