In this study, we monitored the raw materials in home-meal replacement (HMR) products, which have shown more than 63% growth in market size for two years. A total of 89 HMR products were purchased and the DNA barcodes of 112 raw materials in the product samples were analyzed. In order to identify the raw material species, a primer set specific for the 16S ribosomal RNA region of each raw material species was amplified. The amplicon was purified and sequenced, and then used to perform a BLAST search provided by the National Institutes of Health (NIH). The species of the raw material was determined by comparing the nucleotide sequences of the species registered in GenBank with identity and match score. Twenty-four species and three genera were identified from 112 raw materials. Three genera were identified at the genus level because a large number of species belonging to the same genus exist within 98% of the identity criteria. The results of the determination were compared with the available raw materials suggested in the Korea Food Code to determine the Korean name and availability of the foods. Six non-listed species were determined to be edible according to information provided by influential domestic and foreign organizations.

Purpose: This study investigated the association between the mothers' use of home meal replacement (HMR) in their children's meals and the diet quality of their young children. Methods: Three hundred and thirty-seven mothers with five-year-old kindergartners in Sejong city participated in the survey from June to July 2020. The questionnaire consisted of the status of HMR use in children's meals and questions for assessing the nutrition quotient for preschoolers (NQ-P). The subjects were classified into three groups according to the frequency of HMR use in children's meals: using HMR more than three times a week (high-frequency group; [HG], n = 65), one-two times a week (moderate-frequency group; [MG], n = 145), and less than once a week (low-frequency group; [LG], n = 130). Results: The mothers' mean age was 38.3 years. The average monthly cost of purchasing HMRs was highest at 200,000-300,000 won in HG, 50,000-100,000 won in MG, and less than 50,000 won in LG (p < 0.001). The consumption frequency of processed meats, fast foods, processed beverages, and sweet & fatty snacks was significantly higher in the HG group than the other groups. The mean NQ-P score was 60.5 in HG, 63.0 in MG, and 64.5 in LG, showing a significant difference (p < 0.01). In the sub-score according to the three areas, there were no significant differences in balance and environment among the three groups. In the moderation area, however, the score was 44.1 in HG, 51.3 in MG, and 57.5 in LG Group, showing a significant difference (p < 0.001). Conclusion: The increase in HMR use was related to the decreased diet quality in the overall and moderation areas of children's diet. These results support the importance of nutrition education for mothers, which aims to reduce their children's access and exposure to processed foods, such as HMR.

The major design parameters of the anchored sheet-pile wall include the determination of required penetration depth, the force acting on the anchor, and the maximum bending moment in the piling. Blum solved the fixed earth supported wall using the equivalent beam method, assuming that the wall can be separated into upper and lower parts of the point of contraflexure. Design charts help designer by simplifying the design procedure. But they have some difficulties under some Geotechnical and geometrical conditions. For example, the conventional design charts can compute design parameters only when the ground water table exists above the dredge line. In this paper, the design charts which can be used for the ground water table existing under the dredge line are presented. And simplified formulae are developed by regression analysis. It is found that simplified formulae are not only very useful for the practice of design but also they can evaluate the result of numerical methods or design charts.

As the COVID pandemic has been prolonged, 'Contact-free' has emerged as a major trend keyword. Naturally, most people don't go out and eat at home. As a result, sales of products that can easily cooked such as 'meal-kits' have increased remarkably. Although the number of vegetarians is increasing rapidly in Korea, the domestic market has not been activated. Most vegetarians are cooking or eating HMR together due to the lack of vegetarian restaurants and vegetarian menus. According to the survey, the subjects perceive meal-kit as positive as their experience with meal-kit expanded, and this positive perception and the need for vegetarian meal-kits had a positive effect on the purchase intention of the vegetarian meal-kit. This study presents the direction and potential for development of vegetarian meal kits that meet consumer needs. It will be used as a basis for the development of products and expansion of the market for vegetarian meal-kits.

본 연구는 주식시장에서의 체결가격을 균형가격으로 가정하여 계산된 수익률에 관한 통계추정치의 편의에 관하여 분석하고 있다. 주식수익률의 통계적모멘트를 추정하는 것은 주식가격의 행태를 분석하는 연구 및 사건연구등에서 많은 학자들에 의하여 수행되어 왔다. 기존의 대부분의 연구들은 시장에서 체결된 가격이 그 시점의 진정한 균형가격이라는 가정하에 수익률을 계산하고 이 수익률 자료로부터 수익률의 평균, 표준편차, 외도(skewness), 침도(kurtosis) 등의 통계적모멘트를 추정하였다. 그러나 체결가격은 시장의 규칙에 의해 일정한 호가단위로만 거래될 뿐 아니라 매도 또는 매수호가에 거래됨으로써 진정한 균형가격과의 괴리가 있을 수 있게 된다. 본 연구는 주식호가단위의 불연속성과 매도매수호가의 차이로 연한 통계추정치의 편의에 관한 모형을 도출하여 편의의 크기와 특징을 분석하고, 이를 수정하는 간편식을 도출하여 그 유효성을 검증하고 있다. Gottlieb and Kalay(1985), Ball(1988), Cho and frees(1988)등은 1/8 달러의 최소호가단위로 인하여 발생하는 기존의 분산추정치의 편의를 계산하고 이를 수정하는 간편식을 제시하였다. French and Roll(1986)은 휴일이 포함된 기간의 수익률 분산과 평일 분산추정치의 비율이 기간과 비례하지 않는 원인중 하나는 매도매수호가차이로 인한 분산추정치의 편의라는 점을 설명한 바 있다. Choi and Shastri(1989)는 Black and Scholes 옵션가격 결정모형 이 주식 분산값의 크기에 따라 일정한 편의를 보이는 주요한 원인은 퍼센티지 매도매수호가차이와 옵션가격이 모두 진정한 분산치의 정의 함수이기 때문이라는 점을 보였다. Harris(1988)와 최종연(1994)는 주가의 불연속성 및 매도매수호가차이를 동시에 고려하여 기존의 분산추정치가 어떠한 편의를 보이는지에 관하여 분석한 바 있다. 본 연구에서는 최종연(1994)의 연구에서 도출된 모형을 연장하여 국내 주식시장과 같이 주가 수준에 따라 최소호가단위가 변화할 때의 변형모형을 도출하였다. 또한 이 모형에 따라 통계추정치의 편의를 수익률의 표준편차를 중심으로 계산하여 그 정도를 미국시장의 경우와 비교하였고, 그 추정치의 수정 방법에 대하여 호가단위가 변화하는 주가금액이 10,000원 주변일 경우를 중심으로 분석하였다.

Home meal replacements (HMR) are kinds of convenient foods as cooked or semi-cooked foods, which are produced outside of home, to eat directly or after simple cooking in substitution for traditional home meals. Recently the market size for HMR is expanding rapidly around the world due to the changes of global consumer trends, growth of single-person household, increase in economic participation of women, aging population, and so on. The Europe takes over 52.4% of the global market share for HMR in global HMR market, and North America, Asia-Pacific, and Africa-Middle East are following. The most popular HMR products in US and Europe are frozen foods, whereas the market share of chilled products in Asia including Japan, South Korea, and Vietnam are much higher than that in US and Europe. Currently, the trends in HMR is focus on the expansion of the list of products that replace for meals with simple cooking, but it is expected that nutrition-enforced HMR product for aged persons or patients who live alone are requested for the further growth of the HMR market.

Due to the increasing demand for convenience and simplicity, Home Meal Replacement (HMR) has become a key trend in the food service industry. This study researched the current consumer trend and analyzed the national and international HMR product trend, aiming to find useful insights for the field. Results showed that in order to expand the HMR market demand, it is possible to consider diversifying the product category by making customized premium products, such as products for the elderly, infants, patients, and sports players, or products with enhanced nutritional fortification. From the industrial aspect, centralization through Central Kitchen (CK) and implementation of the scientific and advanced ISO and HACCP system are necessary. Lastly, to develop high value-added HMR products, it is deemed essential to utilize the so-called 'food tech', the technology which integrates core technologies of the fourth industrial revolution into the food industry.

Due to the nature of HMR food that is susceptible to contamination, its safety management is becoming more important. The relevant food types in food code corresponding to HMR foods are addressed, and the criteria for hygiene indicator bacteria and food poisoning bacteria, and storage and distribution standards according to the product type were presented. The government's safety management for HMR foods is basically carried out through the Food Sanitation Act. Those who intend to do HMR business must complete business registration or declaration, hygiene education, health examination of employees, and comply with legal obligations such as HACCP application. The government confirms compliance with legal requirements through hygiene inspection and monitoring inspection of products. However, the safety of HMR foods is not realized by the safety management system alone. A food safety culture should be established in which industry workers and consumers carry out actions to ensure food safety.
