Objectives: The present study was conducted to investigate associations between eating style and food intake of 45 female college students during Chuseok holidays. Methods: A ten-day food record was obtained and divided into two parts. The first five days (September 20-24, 2015) were considered as a 'Normal Day (ND 1-5)' and the subsequent five days (September 25-29) as 'Holiday (HD6-10)'. The middle three days (September 26-28) of the holidays were considered as the 'Peak Holiday (PD7- 9)'. Eating behaviors were measured using the Dutch Eating Behavior Questionnaire (DEBQ) and anthropometry was assessed in all study participants. Participants were grouped by cluster analysis according to the mean energy intake of the first three days of the Holiday. Results: Participants had a low-normal range of BMI and they were carefully restricting their food intake at Normal Day. Even the food intake did not exceed 2000 kcal per day during the Peak Holiday. External eating was the most prevalent type of eating behavior, followed by restrained eating and emotional eating. Normal energy and fat intake were correlated with the external eating subscale of the DEBQ. Restrained eating was associated with the weight, BMI, fat mass, waist, and hip girth of the subjects. Compared to the Normal Day, they overate during the Holiday with different eating styles including 'restraint', 'disinhibition', and 'fluctuation'. Therefore, neither eating behaviors nor anthropometry was associated with food intake during the Holiday. Although eating behaviors and anthropometric measures were not different among eating style clusters, the food intakes of disinhibition cluster were higher than those of restraint cluster during all the study periods. Conclusions: Subjects can be classified with the restraint, disinhibition, and fluctuation clusters. However, eating behaviors and anthropometry were not different among three clusters.

This study was performed to offer basic data base on traditional Korean festival foods for a traditional Korean food data integration system, that is based on literature reviews. The Korean lunar calendar has seasonal divisions reflecting traditional Korean holidays. In the past, there were many customs corresponding to emotions, and foods were in accordance with customs, festivals, and seasons. Today, we are well aware of the traditional Korean foods of New Year's Day(Seollal), the Korean Harvest Festival(Chuseok), the First Full Moon Day(Jeongwol Daeboreum), the Winter Solstice(Dongji), and the hottest summer day(Sambok). However, many other traditional Korean holidays are disappearing from the modem Korean life-style. This study made the following classifications for traditional Korean festivals. Seollal(Seol), Ipchun, and Jeongwol Daeboreum in January; Junghwajeol in February; Samjinnal in March; Hansik and Chopail in April; Dano in May; Yudu and Sambok in June; Chilseok and Baekjung in July; Chuseok in August; Jungyangjeol in September; Siwolmuoil in October; Dongji in November; and Napil and Seotdal Geumeum in December. The familiar traditional Korean festival foods are as follows: Seollal's festival foods consist of 5 main dishes, 35 side dishes, 12 kinds of tteok lyou, 21 kinds of hangwa lyou, 2 kinds of emchong lyou, and 3 kinds classified as others; this includes tteokguk, manduguk, galbijjim, sinseollo, jeon, pyunyuk, kimch, tteok, sikhe, sujunggwa, fruits, and seju on Seollal. The festival foods for Jeongwol Daeboreum consist of 3 main dishes, 27 side dishes, 5 kinds of tteok lyou, 3 kinds of hangwa lyou, 4 kinds of emchung lyou, and 3 kinds classified as others; this includes ogokbap, mugeunnamul, yaksik, yumilkwa, wonsobyung, guibalgisul, and burum on Jeongwol Daeboreum. The festival foods for Sambok consist of 6 main dishes, 18 side dishes, 4 kinds of tteok lyou, 3 kinds of eumchung lyou, and 2 kinds classified as others; this includes yukgaejang, imjasutang, youngyejjim, tteoksudan, santtalgihwaschae, and subak on Sambok. Chuseok's festival foods consist of 4 main dishes, 22 side dishes, 18 kinds of tteok lyou, 6 kinds of hangwa lyou, 4 kinds of eumchung lyou, and 3 kinds classified as others; this includes oryeosongpyeon, toranatang, garijjim, dakjjim, namuls, tteok lyou, baehwachae, and fruits on Chuseok. The festival foods for Dongji consist of 6 main dishes, 6 side dishes, 7 kinds of tteok lyou, 1 kind of hangwa lyou, 2 kinds of eumchung lyou, and 1 kind classified as others; this includes patjug, jeonyak, and dongchimi on Dongji. Based on these data, it is recommended that knowledge of traditional Korean festival foods be handed down, preserving and develop their excellence and to further scientific studys.

This study was conducted to research on the observing state of Korean traditional holidays and the traditional foods related to those days through the questionnaires completed by 578 housewives who live in Kangreung, Daejeon, Jeonju, and Daegu area. For data processing, SAS program was employed, and all data was analyzed by frequency, percentage, and $x^2-square$. The results are as follows; 1. In observing the traditional holidays, more than 90% of housewives who answered the inquiry keep up SEOLNAL, DAEBOREUM, and CHUSEOK, whithout regarding regions. There are larger number of people who keep up IPCHUN, JUNGWHAJEAL, and DANOH in Kangreung and SAMBOK in Daegu than that of other regions (p<.001). Compared to general circumstances, CHOPAIL is more commonly celebrated by older class as well as lower educated class (p<.001) Also, the consequence shows that Buddhists observe IPCHUN, SAMJITANL, CHOPAIL, DANOH, SAMBOK, and DONGJI more commonly compared with other classes (p<.001), IPCHUN, SAMJITNAL, (p<.01). DAEBOREUM, YUDU, SAMBOK, JUNGYANGJEOL, OHIL, and DONGJI (p<.001) are celebrated more generally among extended. 2. On inheritance of the traditional holidays, most of the housewives answered that the SEOLNAL, DAEBOREUM, CHUSSEOK, and DONGJI are to be inherited. Compared to general circumstance CHOPAIL is suggested to be inherited by older people (p<.001). The IPCHUN, CHOPAIL, SAMBOK (p<.001), and DANCH (p<.01) are suggested by Buddhists that YUDU and SAMBOK are by nuclear. 3. In preparaing festive foods, DEOKGUK on SEOLNAL, OHKOKBAP and MUKEUNNAMUL on DAEBOREUM, SONGPYEON and GATEUNNAMUL on CHUSEOK, and PATJUK on DONGJI are being made very generally.

This study was conducted to analyze the perception and observance of traditional Korean holidays and preparation of traditional Korean holiday foods among university students in Seoul and the Gyeonggi area in order to further develop modernize and globalize the foods. The analysis revealed that the traditional Korean holidays with the highest perception and observance was Seollal, followed by Chuseok, Jeongwaldaeboreum, Dongji, Dano and Sambok. Traditional Korean festival foods such as Ddukgook, Mandoogook, Sikhye, Injeolmi, Yookgeijang, Kalgooksoo, Songpyon, Galbizzim, Soondubu and Samgyetang also scored high in perception and preparation. Schools were the most frequent route of introduction to Korean traditional festival foods at a rate of 41.6%. Special educational institutions and schools were also high at introduction rates of 38.3% and 19.5% respectively. The results of this study show that traditional Korean festival foods need to be further developed, as the succession of traditional food culture was the highest among 61.4% and 41.3% of the respondents who answered that the 'standardization of flavor, nutrition and cookery' is the most necessary action to popularize seasonal specialty foods.

The main purpose of this study is to examine the suicide pattern during major holidays which are considered to be in high social integration - New Year's Day, Lunar New Year's Day, Harvest Festival (Chuseok) and Christmas. To confirm suicide patterns, this study hypothesized firstly, the number of suicides would decrease before and on each holiday, and secondly, the number of suicides would increase after each holiday. In detail, this study postulated different patterns by marital status and age groups. Utilizing "Causes of Death Statistics" from 2000 to 2005, the number of suicides by marital status and age group on each day is calculated and categorized by holiday. There are four major findings. First, the decrease in the number of suicides during holiday periods is significant. Second, different suicide patterns by marital status are not found. Third, the difference in suicide patterns by age groups is significant. Specifically, there is a decrease in the number of suicides of the old during Lunar New Year's Day and Harvest Festival (Chuseok). On the other hand, there is no changes in the number of suicides of the young during the same periods. Fourth, a decrease in the number of suicides regardless of marital status and age is found at the end of a year. These results mean that increased social integration is functioned as a "suicide immune system." However, each generation has its own main factor that increases social integration.

On 21 September 2010, one of Chuseok holidays in Korea, localized heavy rainfalls occurred over the midwestern region of the Korean peninsula. In this study MTSAT-2 infrared and water vapor channel imagery are examined to find out some features which are obvious in each stage of the life cycle of convective cell for this heavy rain event. Also the kinematic and thermodynamic features probably associated with them are investigated. The first clouds related with the Chuseok heavy rain are detected as low-level multicell cloud (brightness temperature: $-15{\sim}0^{\circ}C$) in the middle of the Yellow sea at 1630~1900 UTC on 20 Sept., which are probably associated with the convergence at 1000 hPa. Convective cells are initiated in the vicinity of Shantung peninsula at 1933 UTC 20, which have developed around the edge of the dark region in water vapor images. At two times of 0033 and 0433 UTC 21 the merging of two convective cells happens near midwestern coast of the peninsula and then they have developed rapidly. From 0430 to 1000 UTC 21, key features of convective cell include repeated formation of secondary cell, slow horizontal cloud motion, persistence of lower brightness temperature ($-75{\sim}-65^{\circ}C$), and relatively small cloud size (${\leq}-50^{\circ}C$) of about $30,000km^2$. Radar analysis showed that this heavy rain is featured by a narrow line-shaped rainband with locally heavy rainrate (${\geq}50$ mm/hr), which is located in the south-western edge of the convective cell. However there are no distinct features in the associated synoptic-scale dynamic forcing. After 1000 UTC 21 the convective cell grows up quickly in cloud size and then is dissipated. These satellite features may be employed for very short range forecast and nowcasting of mesoscale heavy rain system.

Objective : 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. I found that ingredients in Si-jeol-sik of Autumn are helpful for strengthening one's life force. Method : The study found that si-jeol sik for fall season has strong characteristic of casting out demons. When making songpyeon(half-moon-shaped rice cake) for Chuseok (Korean Thanksgiviing Day), they are steamed with pine needs spreaded underneath because pine needles are believed to have power in casting away evil spirits. For harvest ceremony, which were frequently held in October, people consumed steamed rice cakes garnished with red beans, which were considered to negate bad fortunes. Result : To prevent respiratory diseases caught esaily in fall due to wide daily temperature difference and dry weather, white good ingredients such as radish, pear, and taro are used. Conclusion : Main fall holidays are Chil-soek, Baek-Jung, Chu-seok. The best feature of Si-jeol-sik for fall season is that they cast out demons. Also, fall si-jeol-sik consist of many white ingredients for protecting lungs.

With the improvement of living standards and economic development, electricity consumption continues to grow. The electricity is a special energy which is hard to store, so its supply must be consistent with the demand. The objective of electricity demand forecasting is to make best use of electricity energy and provide balance between supply and demand. Hence, it is very important work to forecast electricity demand with higher precision. So, various forecasting methods have been developed. They can be divided into five broad categories such as time series models, regression based model, artificial intelligence techniques and fuzzy logic method without considering special-day effects. Electricity demand patterns on holidays can be often idiosyncratic and cause significant forecasting errors. Such effects are known as special-day effects and are recognized as an important issue in determining electricity demand data. In this research, we developed the power demand forecasting method using ELM(Extreme Learning Machine) for special day, particularly, lunar new year and Chuseok holiday.
