Since the late 19 century, the Choseon dynasty forcibly opened the door to western countries, including Japan. In addition, cultural propagation called 'modernity' caused subtle changes in dietary life. Based on the theory of colonial dual society, this study examined the dietary modernity in Kyungsung (mid 1930s~early 1940s) when 50 years had passed since the Open-Door policy. Three films, (1934), (1936) and (1941) (those made in 1930s~1940s) were analyzed. Twenty six scenes [14 scenes from , five scenes from , and seven scenes from ] related to the dietary life from films were chosen and classified according three criteria (degree of modernization, main influential countries, and benefit groups from modernization). The degree of modernization of all films was more than 80%. The average proportion of the countries that affected modernization were western (35%), western-Japan (28%) and Japan (20%). Approximately 33, 53 and 14% of the upper, middle, lower classes, respectively, benefited from diet modernization. The main places where modernized dietary culture could be enjoyed were cafes, western restaurants, tea rooms, and hotels. The main food or beverages that were considered as modernized dietary culture were liquor (especially beer), coffee, and western meals. People in Kyungsung in the mid 1930s~early 1940s experienced modernity in dietary life differently according to the social classes and these culture changes were generally accepted as a symbol of modernity.

In this paper, in order to investigate the efficiency of solar power generation system operation, we have studied operation cases such as generation amount, utilization rate, and generation time, and the following conclusions were obtained. The amount of power generation in 2017 was 1,311.48 MWh, and the amount of power generation in 2018 was 1,226.03 MWh. In 2021, 1,184.28 MWh was generated, and 90.30% compared to 2017, and the amount of power generation decreased by 1.94% every year. The deterioration of photovoltaic modules could be seen as one cause of the decrease in power generation. 1,977.74 MWh was generated in the spring, and 1,621.77 MWh was generated in the summer. In addition, 1,478.87 MWh was generated in the fall, and 1,110.55 MWh was generated in the winter, showing a lot of power generation in the order of spring, summer, fall, and winter. From 2017 to 2022, the seasonal utilization rate, daily power generation time, and daily power generation were investigated, and it could be seen that the spring utilization rate varies from 19.29% to 16.99%. It could be seen that the daily generation time in winter decreased from 2.67 hours to 2.13 hours, and in spring it generated longer than spring from 4.63 hours to 4.08 hours. In addition, the daily power generation in winter also decreased from 2.67 MWh to 2.13 MWh, and in spring it decreased from 4.63 MWh to 4.08 MWh, but it could be seen that it is more than in winter.

Jambangee's advertisements in spring 1998 attracted public attention by the differentiating message of 'nationalism'. The purpose of this paper is to interpret Korean youth's culture of consumption, value, thought and culture expressed in these advertisements. The semiotic analytic method of F. Saussure and R. Barthe were used. Metaphor and metonymy as interpretive tools were used. Two levels of meaning, denotation and connotation were examined, and idelogies and mythologies were sought. Contrary to the most of jean advertisements which show youth, characteristic style, western life style and westernized beauty, refinement, materialism, and social differentiation, Jambangee's advertisement showed nationalism and patriotism. These advertisements criticized that preference of imported goods and ostentation of purchasing power brought crisis of economy and I.M.F. system. Jambangee's jeans symbolized as the meaning of nationalism and patriotism were suggested as a way to save our country. Jambangee's advertisements are meaningful. Because we had accepted western fashion passively so far, but for the first time Jambangee applied Korean design elements to jeans and gave new meanings to them through the 'nationalism'campaign.

This exploratory research compares two particular features of coffee culture, namely the reason why a particular coffee shop is frequented and the reason for going to the chosen coffee shop in Italy and South Korea. A survey was carried out targeted at current undergraduate university students in both countries with data being collected in the late spring and early summer of 2017. The main impetus for this research was to investigate the aforementioned areas given the fact that Italy has such a long standing coffee culture that dates back centuries and is still an industry dominated by independent coffee houses while the Korean coffee industry started developing in the early 1980s and taking off after the 1988 Olympic Games. The Korean coffee industry, in contrast, is driven by the franchise coffee shops such as Starbucks, $Caf{\acute{e}}$ Benne, and The Coffee Bean among others. While both countries have well developed coffee cultures, they developed along very different lines. Data collected from respondents are tabulated and presented followed by an analysis and interpretation of the data. Finally, some suggestions on how to conduct further research in order to better understanding the underpinnings and contributing factors in understanding consumer choice and coffee culture in both Italian and Korea are suggested.

Geothermal springs in India, formed as a result of volcanic or tectonic activities, are characterized by high temperature and relatively abundant reduced compounds. These thermal springs are inhabited by characteristic thermophilic organisms including cyanobacteria. Cyanobacteria are among the few organisms that can occupy high temperature aquatic environments including hot springs. In alkaline and neutral hot springs and streams flowing from them cyanobacteria can form thick colourful mats that exhibit banding patterns. The present investigation involves study of mat forming cyanobacterial flora from hot springs located in Bakreswar, West Bengal, India. The important species found are Synechococcus bigranulatus, S. lividus, Gloeocapsa gelatinosa, G. muralis, Phormidium laminosum, P. frigidum, Oscillatoria princes, O. fragilis, Lyngbya lutea, Pseudanabaena sp., Calothrix thermalis, and Fischerella thermalis. Their distribution pattern in relation to physico-chemical parameters of spring water has also been studied. Three cyanobacterial strains of the above mentioned list were grown in culture and their pigment content and nitrogen fixing capacity were also studied. Nitrogen fixing capacities of Calothrix thermalis, Nostoc sp. (isolated in culture) and Fischerella thermalis are 5.14, 0.29, and 2.60 n mole $C_2H_4/{\mu}g$ of Chl-${\alpha}$/hr respectively. Carotenoid : Chlorophyll-${\alpha}$ ratio of four mat samples collected from Kharkunda, Suryakunda, Dudhkunda and bathing pool are 2.45, 1.60, 1.48, and 1.34, respectively. Higher value of Carotenoid : Chlorophyll-${\alpha}$ ratio coincided with higher temperature.

This study aimed to develop unique, local "food tourism" products by finding specialized items that combine tourist attractions, such as folklore or hot springs. Traditional ingredients were analyzed with ancient texts for the methods of research. A brand image was made possible utilizing hot spring lore and other regional stories. The tofu products were produced using local specialty beans. Products, such as tofu residue cake and willow bean tea, were made with the tofu residue. After the products were completed, the sensory test began at the local tourist attraction. Asan City's food tourism product willow tofu was made with beans that were given as compensation for building the Onyang temporary palace according to the Annals of the Joseon Dynasty and the willow tree that appears in Sunshin Lee's anecdotes. After the preference test between normal tofu and willow-extract tofu was conducted to measure the product potential of willow tofu, among the sample extracts, 0.04% of the willow extract showed a significant preference. The hot spring tofu-residue cake was baked using tofu residue and vegetable olive oil to substitute for animal oil, such as butter, or margarine. After the sensory test targeting the adults was conducted, both products displayed significant product potential with average scores above 5.0. Willow tree bark, which has antioxidation and anti-inflammatory effects without a bitter taste or strong smell, was proven to bean appropriate ingredient for leached tea. The nutty flavor of leached tea was enhanced by roasted green kernel black beans and willow tree bark. The sensory test showed that the leached tea and tofu received a high preference rating on both color and flavor.
