The East Asian monsoon is generally accompanied with the quasi-stationary front along the northern and northwestern periphery of the subtropical anticyclone in the boundary zone of the polar cold air mass and the tropical warm air mass. The rainy season in Korea has been called as Changma since the middle of 1500s. In meteorology, the rainy season with the quasi-stationary front, the Changma front, during the early summer has been defined as the Changma since 1905. The difference of meaning on Changma between meteorologists and the general public sometime does give a confusion. For example, the heavy rainfall event after the retreat of Changma is recognized as Changma by the general public, but not by most of meteorologists. The decision of the onset and retreat dates of Changma among the meteorologists is also ambiguous because of different viewpoints on the definition of Changma. In this study we survey the etymology and definition of Changma.

Omija, the major material of omigalsu, has liver protective and antioxidant effects, while mung bean has detoxification effects. A series of studies were conducted to standardize the traditional recipe for omigalsu to develop traditional functional drinks made from Omija extract and mung bean juice. Study 1 was designed to determine the optimal conditions for Omija extraction and mung bean juice. A higher water temperature and longer immersion time was associated with higher, free sugar and organic acid contents of omija extract; however, sensory evaluation revealed that the optimal extraction conditions for the highest acceptability, proper taste and red tone were $23^{\circ}C$ and 18 hrs of immersion. Conversely, the pH of the mung bean juice produced by varying the immersion time (5 hr, 11 hr, 17 hr) was found to be neutral, containing small levels of organic acid and free sugar, and showing a yellow tone. The results of the sensory evaluation also showed that the optimal conditions for taste, flavor and yellowness of mung bean juice was 5-hour-long immersion. Study 2 was designed to determine the optimum mixing ratio of omigalsu concentrate. Sensory evaluation revealed that the contents of sugar and total free sugar were highest when the mixing ratio among omija extract, mung bean juice and sugar was 1:1:20%, indicating that these conditions produced the most attractive color and highest overall acceptability. Study 3 was designed to determine the optimum dilution magnification for omigalsu. Sensory evaluation during summer revealed that the omigalsu produced by mixing 54 g of omigalsu concentrate into 200 cc water of $4^{\circ}C$ or $80^{\circ}C$ was most preferred, while during winter. Overall, the optimum dilution magnification for omigalsu was 4.7~5.4.

The purpose of this study was to investigate Japanese female marriage immigrants' dietary life and health-related characteristics after immigration to Korea. A survey was conducted with Japanese women married to Korean men and having one child or more aged 7 to 18 years old. Data were collected from 243 women during the summer of 2014. A total of 204 questionnaires were analyzed, after excluding 39 questionnaires with a high percentage of incomplete responses (84% analysis rate). Over 85% of respondents were the members of the Unification Church, and over 92% of respondents had stayed in Korea for longer than 10 years. Based on the overall mean score for dietary adaptation level (3.68 out of 5 points), respondents were classified into two groups: low dietary adaptation group (mean score 3.12) and high dietary adaptation group (mean score 4.19). The collected data were compared between the two groups. The high dietary adaptation group reported higher percentages of decreasing consumption in processed food, confectionary, and bread than the low dietary adaptation group after immigration to Korea. A higher percentage of respondents in the high dietary adaptation group perceived their health status as good and reported changes that led to a healthier dietary life after immigration to Korea compared with those in the low dietary adaptation group. In conclusion, Japanese female marriage immigrants well adapted to Korean dietary life tended to eat healthier and perceive health status better compared with those who were not well adapted. The results of this study could be useful for prospecting dietary life and health-related characteristics of immigrant women in the long term after immigration to Korea.

There is an increasing curiosity in Nordic as well as Far East Asian countries about senior cohousing, where the middle-aged and elderly people, 55+. form a community for independent living. What are the ideas behind senior cohousins? Why are people moving to senior cohousing community? What may senior cohousing provide and mean for individuals and groups of the elderly? Is senior cohousing a sustainable idea for future generations of elderly people? There is a curiosity among elderly people looking for interesting alternatives. Municipalities and state authorities hope that senior cohousing can contribute to the welfare of the elderly as the scope far support by the public sector is decreasing. Actors in the building sector are interested In investment and meeting the demands. In Denmark and Sweden the senior cohousing concept had a revival around 1985. In Denmark there has been a vivid discussion and plenty of books have been published. In Sweden there are few evaluations but an increasing interest. From different points of view, Danish, Swedish and Nordic as well as Far East Asian countries, there is a concern to explore and compare to get more facts and deeper understanding far further actions. This is a comparative study of inhabitants' life satisfaction in cohousing communities in Denmark and Sweden. The study is based on discussions with cohousing providers, study-visits in cohousing communities and a questionnaire to residents themselves. Study-visits took place during springtime and the questionnaires were handled spring and summer of 2002. 655 seniors responded to the questionnaire from 14 seniorbofae llesskaber (rented or housing cooperatives) in Denmark, 11 seniorhus within the SABO sector (municipality owned housing with rental apartments) and 8 housing cooperatives initiated by the Seniorgarden Housing Company in Sweden. Data were analyzed by SPSS program, using frequency, percentage, cross-tab and chi-square test. This paper focused three major areas of interest; 1)characteristics of the inhabitants. 2) participation in common activities and mutual cooperation among residents and 3) evaluative outcomes from the inhabitants' points of view. Mainly the inhabitants expressed quite positive experiences of their living environment and everyday lift and a few difference was found in life satisfaction between Denmark and Sweden.

A Land cover map over East Asian region (Kongju national university Land Cover map: KLC) is classified by using support vector machine (SVM) and evaluated with ground truth data. The basic input data are the recent three years (2006-2008) of MODIS (MODerate Imaging Spectriradiometer) NDVI (normalized difference vegetation index) data. The spatial resolution and temporal frequency of MODIS NDVI are 1km and 16 days, respectively. To minimize the number of cloud contaminated pixels in the MODIS NDVI data, the maximum value composite is applied to the 16 days data. And correction of cloud contaminated pixels based on the spatiotemporal continuity assumption are applied to the monthly NDVI data. To reduce the dataset and improve the classification quality, 9 phenological data, such as, NDVI maximum, amplitude, average, and others, derived from the corrected monthly NDVI data. The 3 types of land cover maps (International Geosphere Biosphere Programme: IGBP, University of Maryland: UMd, and MODIS) were used to build up a "quasi" ground truth data set, which were composed of pixels where the three land cover maps classified as the same land cover type. The classification results show that the fractions of broadleaf trees and grasslands are greater, but those of the croplands and needleleaf trees are smaller compared to those of the IGBP or UMd. The validation results using in-situ observation database show that the percentages of pixels in agreement with the observations are 80%, 77%, 63%, 57% in MODIS, KLC, IGBP, UMd land cover data, respectively. The significant differences in land cover types among the MODIS, IGBP, UMd and KLC are mainly occurred at the southern China and Manchuria, where most of pixels are contaminated by cloud and snow during summer and winter, respectively. It shows that the quality of raw data is one of the most important factors in land cover classification.

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.

This study was investigated about preparation of ice at home and developing points which met consumer's demand that was focused on auto icemaker. According to purposive quota sampling method, residences in Seoul and Kyunggi-do area were selected and interviewed by trained interviewer at August 1995. The results were as follows: 66.3% of respondent usually prepared ice in ice-making container of refrigerator and used when they needed. 85% of them used ice in summer and seldomly used in other seasons. Boiling water with barley was major drinking water(45.6%), and broiled or purified tap water was used to make ice(38.6%) commonly. Numbers of ice-making container were two(66.0%). Above 50% of respondents replied that they felt off-flavor in ice usually. After felt off-flavor, 54.7% of respondent threw away the ice, some of them used off-flavored ice after treatment to washing with water. 64.9% of respondents thought that the origins of off-flavor was the flavor of refrigerator itself. The consumer's expectation of developing points were as follows. The most priority of developing points was to make ice quickly, the next was to develop auto ice maker and ice storage container, to make different size of ice. Less expected points were to make more clear ice and large volume of ice in one time. The recognition about auto ice maker was slightly low(35% of respondents), but 67% of them wanted to develop auto ice maker.

This study aimed to investigate factors related to Chinese female marriage immigrants' dietary adaptation. An in-person survey was conducted by a research institute on Chinese female marriage immigrants married to Korean men, having one child or more aged 1~6 years old, and having resided in Korea for at least 1 year before the survey. Data were collected from 309 respondents comprising 151 Han Chinese and 158 Korean-Chinese during the summer of 2013. About two-thirds of respondents were in their 30s and had resided in Korea for 5 to 10 years. Based on the overall mean score for dietary adaptation level (3.50 out of 5 points), the respondents were classified into two groups: low dietary adaptation group (mean score 3.11) and high dietary adaptation group (mean score 3.81). The results of comparative analysis between the two groups showed that the levels of acculturation (p<0.01) and healthy dietary behavior (p<0.01) for the high dietary adaptation group were significantly higher than those of low dietary adaptation group. The number of respondents of the high dietary adaptation group reporting increased food diversity (p<0.01) and decreased frequency of skipping meals (p<0.01) was significantly higher compare to the low dietary adaptation group. Multiple regression analysis was conducted to identify factors related to dietary adaptation. General characteristics, levels of acculturation, and healthy dietary behavior were included as independent variables. As a result, levels of acculturation and healthy dietary behavior as well as education level, monthly household income, and length of residence in Korea were associated with dietary adaptation. In conclusion, Chinese female marriage immigrants showing acculturated and healthy dietary behaviors adapted well to Korean dietary life. The results from this study suggest that diet-related adaptation support programs for Chinese female marriage immigrants may positively affect their acculturation and dietary behaviors.
