The changes in ingredients, seasonings and cooking methods of Japchae in Korean cook books published from the 1600s to the 1960s were investigated in this study. Japchae was a royal dish enjoyed by Kwanhaegun of Joseon Dynasty and interesting historical story is contained in it. Kwanghaegun Ilgi in 1608 showed that Japchae was Kwanghaegun's favorite dish. Therefore, it has been thought that Japchae was created in the 17th century. Wonhaengeulmyojeongrieugye in 1796 described bellflower Japchae and mungbean sprout Japchae. The traditional Japchae was made without glass noodle called dangmyeon. Eumsikdimibang in 1670 first introduced traditional Japchae, which was made with 20 different ingredients and then served with topping sauce made of pheasant broth, strained soybean paste and wheat flour. Japchae in Kyugonyoram(1896) was prepared by mixing mungbean sprout, watercress, gonjasoni, tripe and yukhwe with mustard. The current style Japchae with glass noodle first appeared in the 1920s and became popular in the 1950s because the traditional Japchae was described in cook books until the 1940s. There were two ways of preparing current style Japchae. Yijogungjeongyoritonggo in 1957 described Japchae was made by mixing the boiled glass noodle with other ingredients and seasonings together. On the other hand, Japchae in Urinaraeumsikmandeuneunbeob(1960) was prepared by seasoning first with other ingredients, and then mixing boiled glass noodle. A variety of ingredients - vegetables, mushrooms, meat, fish, pheasant, beef tong, sea cucumber, gonjasoni and pear - has been used to prepare Japchae. Japchae has been seasoned with ginger, soy sauce, black pepper, sesame salt, sesame oil, oil, leek, garlic, salt, sugar, vinegar and mustard. Egg strips, pine nut, thin strips of Shiitake and stone mushroom, red pepper threads, Chinese pepper(cheoncho), black pepper and ginger were used for garnishing.

In this research traditional Buddhist dietary life style was studied as an alternative for both saving water and decreasing water pollution from household. A traditional dietary life style for the Buddhist monks, called Balwoo Gongyang, and its modernized one for citizens, called Dish Gongyang were examined with water use amount, wastewater quality and pollutant loading rate, and were compared with the kitchen wastewater from household. And several types of natural detergent were also examined to compare their effect on the wastewater quality and pollutant loading rate. This research was carried out using the wastewater from Balwoo and Dish Gongyang in J building located in Seoul. Wastewater generation from Balwoo Gongyang that was about $1.0{\ell}$/capita/day was very low compare to that from dish washing in normal household($32.6{\ell}$/capita/day). In case of Dish Gongyang, water generation was 1.8 times higher than that from Balwoo Gongyang, but it was just 1/19.2 of normal household. When the wastewater quality of Balwoo Gongyang was compared with the kitchen wastewater of normal household, SS was 1/16($15mg/{\ell}$), COD was 1/7($22.1mg/{\ell}$), BOD was 1/9($24.1mg/{\ell}$) and T-N was 1/16($1.7mg/{\ell}$). Pollutant loading rate from Balwoo Gongyang was very low, COD 18.0 mg/capita/day, SS 12.3 mg/capita/day and it was 1/290, 1/639 of that from dish washing wastewater from normal household, respectively. Pollutant loading rate from Dish Gongyang was also low 1/13(SS)~1/144(TN) compared to dish washing wastewater from normal household. As a natural detergent, used water from washing rice showed very low pollutant loading rate. It was concluded that Dish Gongyang that was a modernized and simplified dietary life style of Balwoo Gongyang, was very eco-friendly. Especially when it was combined with natural detergents using by-product from cooking process, its effect on the water pollution was very low.

In order to save the energy in apartment houses, it is essential that the energy amount consumed in heating per household should be surveyed and analyzed according to heating method, which can be classified into unit, central and district methods. As a basis, we selected the household with nominal area of 32 py. because it accounts for the most percentage in Korea. It is estimated that the gas amount for cooking is 90 ㎥ and the energy amount for hot water supply is 11.41 GJ for a year, which is necessary to calculate the heating energy. Through the survey of actual energy consumption in Seoul and Gyeonggi, the energy amount used in heating can be obtained according to the heating type: 26.02 GJ/year for the unit heating, 28.09 GJ/year for the central heating and 40.61 GJ/year for the district heating.

This study was conducted in order to better understand the local and specialty foods of the Yeong-ju region. This study provides basic data for new menu development and commercialization. The results of 384 surveys, which were conducted to determine traditional rice cake production methods and their traits, were analyzed. Samgyetang was ranked top in the survey on recognition, public interest, and frequency of the local foods. Dakjuk was ranked second, followed by Baechujeon and Bopguk, in order. The levels of recognition and preference of specialty foods were in the order of hasuo, peach, apple, and meat. Among the answers in the survey on the popularization and commercialization of local foods, changing of the cooking style for younger generations' taste was considered to be the most important. Holding events to promote regional specialty foods and initiate the public to traditional cooking styles were listed sequentially by importance. The survey results show that promotion of local foods through education, and as well as incorporation of new ingredients are both highly effective ways to commercialize local foods for tourism. The results also indicate that taste, nutrition, and appearance of food should be considered in order to improve quality.

To examine the key success factors for long-lasting restaurants, we visited 10 restaurants with 30 or more than 30 years of tradition, located in Seoul and Gyeonggi-do districts, to research these restaurant menus and customer characteristics by observation and interview. The results were analyzed using descriptive statistics. The outstanding feature noted was that each and every restaurant had its own simple and specialized menu. We found that this feature created a virtuous circle that reinforced itself through a positive feedback loop. The simple and specialized menu increased both the cooking efficiency and food quality while it reduced both food and labor costs, this enabled the customers to eat at an affordable price and have generous servings. This lead to customer satisfaction and revisits to the restaurant, which triggered word-of-mouth referral and expansion of their customer base. This in turn created higher operating profit margins that could be reinvested in the business. The secret recipes for cooking, invented by their founders, were passed on from generation to generation. Their customer base included customers of all ages from children to senior people. And their regular customers consisted of neighboring office workers and families traveling from a long distance. We hope that our findings on long-lasting restaurants, especially of the virtuous cycle created due to the simple and specialized menus with secret recipes, will contribute to the development of Korean style long-lasting restaurant model.

Indoor air quality tends to be the dominant contributor to personal exposure because most people spend over 90% of their time indoors. For some contaminants, exposure to indoor air poses a potentially greater health threat than outdoor air exposures. Indoor nitrogen dioxide ($NO_2$) levels are mainly affected gas range, flue gas spillage, kerosene heaters, wood-burning appliances and cigarette smoke. In addition, indoor $NO_2$ levels are influenced by such house characterization as surface reaction and air exchange rate. In this study, the measurements of indoor and outdoor $NO_2$ concentrations were taken using identical protocols, and information was collected on housing characteristics using identical questionnaires in 14 houses out of 15 houses for daily 30 daily 30 days in Brisbane, Australia.The usage of gas range was the most contributing factor in indoor $NO_2$ concentration in relation to house characteristics. Average indoor and outdoor ratios of NO2 concentration in electronic and gas cooking houses were $0.6{\pm}0.1$ and $0.9{\pm}0.2$, respectively. The frequency distributions of $NO_2$ concentration in each house were approximately log-normal Geometric mean of indoor $NO_2$ concentrations of electronic and gas cooking houses for daily 30 days ranged from 2.5 ppm to 11.5 ppm with a mean 6.8 and from 4.7 ppm to 28.6 ppm with a mean 15.6 ppm, respectively. The $NO_2$ concentrations between electronic and gas cooking houses were significantly different (p<0.05). Since each house has different life-style and house characteristics, sampling interval to measure the $NO_2$ levels was recommended above 7 days.

Background: Changes in dietary practices are known to be associated with changes in the health and disease pattern of a population. This study aimed to qualitatively explore the perception of colorectal cancer patients regarding causes of colorectal cancer and the influence of diet. Materials and Methods: Twelve respondents from three major ethnicities in Malaysia were selected from the quantitative study on dietary pattern and colorectal cancer carried out earlier in this study. In-depth interviews (IDI), conducted from April until June 2012, were mainly in the Malay language with additional use of English and continued until the saturation point was reached. All interviews were autorecorded so that verbatim transcriptions could be created. Results: Causes of colorectal cancer were categorized into internal and external factors. The majority of respondents agreed that there is an association between Western foods and colorectal cancer. Malaysian traditional diet was not related to colorectal cancer as less preservative agents were used. Malaysian diet preparation consisting of taste of cooking (spicy, salty and sour foods) plus type of cooking (fry, grilled and smoked) were considered causes of colorectal cancer. All respondents changed their dietary pattern to healthy food after being diagnosed with colorectal cancer. Advice from doctors regarding suitable food for colorectal cancer was useful in this regard. Conclusions: Eating outside, use of food flavoring ingredients and preservative agents were considered to be the main factors causing colorectal cancer. All respondents admitted that they changed to a healthy diet after being diagnosed with colorectal cancer.

The purpose of this study is to find differences in dietary patterns through menu analysis by economic status. The data was obtained from the 1998 and 2001 National Health and Nutrition Survey of Korea. The main variables were economic status, sex, and area by urbanization. The economic status was classified into low, middle, high, and top classes using a poverty line based on the 1998 and 2001 minimum standard cost of living. The areas were divided into metropolis, small city, and rural areas. The dishes of 3 meals were classified into 29 categories by cooking method. The most frequent pattern was "rice + soup + kimchi". The frequency of this Korean basic dietary pattern was the lowest in the top income class and metropolis areas, while the highest in the low income class and rural areas. The frequency of Korean recommended dietary pattern, that is, "rice + soup or stew + kimchi + side dish" was the highest in the top income class. The metropolis group preferred side dishes using meat and a cooking method that saved time, but the rural group preferred side dishes using vegetables and cooking methods that take a longer time. In comparison of dietary pattern between male and female by economic status, the higher economic status, the male's dietary patterns showed more side dishes than those of female. But the main side dish was kimchi in male low class. Consequently, the major dietary pattern in Korea is rice-style, though the western pattern is increasing in the top income class, especially in metropolis areas. Therefore, to make a better dietary pattern, we should develop and spread low-priced recipes of various side dishes and teach financial skills such as ability to make a food budget for lower income classes. Also, we should emphasize the importance of the balance between meat and vegetables and traditional diet and western diet for the top income class, especially in the metropolis areas.
