The purpose of this research was to develop healing food dishes for the vitalization of forest healing tourism in agricultural areas by enhancing satisfaction of food experiences by visitors to Mount Chungnyeong, Jangseong. Results from site visitation by three professors from food-related departments, association opinions, Jangseong-gun policies, and research materials relating to healing foods were applied for the preparatory experimental cooking, and the final dishes were selected through a food demonstration event. As a result of observation during the site visitation, the main dishes of the subject restaurant appeared to be limited to Samchae Bibimbap, Samchae Ddeokgabi, and Korean set menu items, revealing a limited selection for tourists and referencing a failure to induce customer attraction and long-term stay. Development of a menu conforming to the image of forest healing at Mount Chungnyeong is desperately needed. As a result of applying the results of the surveys from visitors to Mount Chungnyeong, the types of dishes preferred appeared to be Korean table d'hote and Bibimbap, and pork was preferred as the $entr{\acute{e}}e$. The characteristics of preferred dishes appeared to be based on tradition and regionality. Thus, Forest Healing Savory Dish, Yellow Health Dish, and Samchae Kalguksu applying the policy direction of the Yellow City, Jangseong-gun and the image of Jangseong-gun based on Confucianism were developed. Tourists may further enhance the effectiveness of forest healing through foods based on dishes by adding traditional taste using seasonal food ingredients and local specialties, which can contribute to the vitalization of forest healing tourism.

Mesophilic aerobic bacterial counts were measured and compared for seasoned soybean sprouts produced in different seasons and sold in different market types. Very significant differences in microbial counts were found among seasoned soybean sprouts produced in different seasons (winter, spring, and summer) and among different market types (a traditional market, discount store, and department store). However, there was no significant difference among the stores within each market group. The interactions were significant at a 1% significance level. The variance of summer counts was much lower than spring and winter counts. Discount and department stores showed a higher variation in microbial counts than traditional markets. The microbial counts differed substantially from season to season in the same market group (summer > spring > winter) except between spring and summer in traditional markets. The microbial loads in the winter and spring seasons of seasoned soybean sprouts in traditional markets were clearly higher than in other market groups, while discount stores had the highest microbial count in summer.

This experiment was carried out to examine the seasonal changes in feed intake and feeding behavior in Korean spotted deer under farmed condition to obtain basic information for efficient feeding management. The seasonal daily gain was the highest (p<0.05) in summer and the lowest (p<0.05) in winter. Dry matter intake (DMI) was the highest (p<0.05) in spring (2,685 g/day) and the lowest in winter (1,929 g/day). Intake of roughage in the DMI was the greatest in spring and that in winter was significantly lower (p<0.05) than in spring. Also DMI, expressed in terms of metabolic body weight ($kgW^{0.75}$), was 85.5 g, 70.6 g, 70.9 g and 65.1 g for spring, summer, autumn and winter, respectively, and thus was the highest in spring and the lowest in winter (p<0.05). Deer exhibited similar eating patterns, comparatively short and frequent periods, in all seasons. They showed comparatively intensive patterns of rumination during midnight for autumn and winter and relatively continuous patterns of chewing activity during spring and summer. There were no significant differences in seasonal eating time and ruminating time. However, exercise time was the greatest for winter and the lowest for summer and there was a significant difference (p<0.05) between summer and winter. Although not significant, eating time per 100 gDM ingested tended to be short in spring and summer and long in autumn and winter. Ruminating time per 100 gDM ingested was the shortest (p<0.05) in spring compared with in other seasons. The conclusion can be drawn that since deer have seasonal differences in feed intake and feeding habits, it is necessary to establish and develop an efficient feeding system for deer.

Objectives: This study was undertaken to assess the sanitary conditions in the kitchens of food court/cafeterias and determine seasonal variations. Methods: We measured environmental factors (air temperature, relative humidity, illumination intensity, noise level), and dropping airborne microbes (bacteria and fungi) in the kitchens of eight food court/cafeterias in four seasons (January, April, July, and October). Air temperature and relative humidity were measured with in/out thermo-hygrometers at 1.2-1.5 m above floor level. Illuminance measurement was performed through the multiple point method of Korean Standards (KS). Noise level was measured by the standard methods for the examination of environmental pollution (noise and vibration) of Korea. The estimation of dropping airborne bacteria and fungi was performed through use of Koch's method. Results: The highest kitchen air temperature was in July, and the lowest in January. The average temperature surpassed $21^{\circ}C$ throughout the seasons, suggesting a higher temperature than required for the safe handling of food. Humidity in all the kitchens was measured in the range of 50-60%. Half of the kitchens showed illumination intensities below 300 Lux in April. It was found that the sound pressure level of noise in almost all of the kitchens was higher than 85 dB (A). The highest levels of dropping airborne bacteria and fungi were noted in July. The numbers of airborne bacteria were higher than those of fungi. The levels of dropping airborne bacteria and fungi were affected by air temperature, relative humidity, season, and place. Conclusions: This study indicates that the kitchen environments were unqualified to supply safe food. The hygiene level of the kitchens should be improved.

Jeol-sik, (festive seasons every 15 days based on sun cycle), refers to both Korean Traditional Festival food(jeol-sik), intertwined between months, and in-season meals(si-jeol-sik) in which the ingredients used are produced in each and one of the four season. Si-jeol-sik is a kind of recommendatory food, which is combined to seasonal changes. I found that ingredients in Si-jeol-sik of spring are helpful for strengthening one's life force. Moreover, the ingredients also reflects seasonal changes. The main ingredient of Si-jeol-sik in January(in lunar year) is rice. Rice is good for upgrading one's stomach qi(energy). Rice continues to be used in February. In addition, some greens are included in February Si-jeol-sik as to help defecation. In March, the ingredients become diverse and abundant. The main concern in the ingredients found in March is not limited to stomach qi. These changes of ingredients are in line with the concept of 'health maintenance', which is written in Huangdi Neijing. The writing teaches the wisdom of adaptation to nature. Si-jeol-sik's basic idea is maybe giving people some food, which includes useful elements to help them survive through a season or the next season. They can be also explained properly by the help of five flavours theory. According to Huangdi Neijing liver is main organ of spring. So liver is more important than other organs in spring. And the most efficient way for liver is supplying sweet or sour food. Interestingly, there are many sweet elements in Si-jeol-sik of spring.

Food and feeding habits of Labeobarbus intermedius were studied from the newly constructed Ribb Reservoir, Ethiopia during the dry (December-March) season and wet season (June-August) of 2021. The objective of the study was to determine the diet composition, seasonal variation, and ontogenetic dietary shift in the diets of the dominant cyprinid fish in Ribb Reservoir. In this study, frequency of occurrence and volumetric analysis methods were used to present the results. From a total of 203 fish samples, 132 (65%) guts contained food items. Macrophytes (29.4%), phytoplankton (27.2%), detritus (14.8%), and insects (13.6%) were the major food items in the diets volumetrically. During the dry season, L. intermedius was mainly dependent on phytoplankton (58.2%), insects (15.2%), and zooplankton (13.7%) volumetrically. Whereas, macrophytes (50.3%) and detritus (23.3%) were the dominant food items in the wet season. The frequency occurrence and volumetric contribution of the diets of L. intermedius varied significantly (χ² test, p < 0.05) between seasons. Schoener's diet overlap index revealed a slight ontogenetic dietary shift in the diets of L. intermedius. While insects, nematodes, and zooplankton were the main diets of small-sized L. intermedius, macrophytes and detritus were ingested by large-sized L. intermedius. Generally, L. intermedius fed both plant and animal-origin food items and is considered an omnivorous feeder in Ribb Reservoir.
