This study was conducted to investigate the weaning practice of 170 infants, aged 6 to 20 months, in Sockcho city Kangwon province. Informations on the infant feeding were obtained by interviewing mothers in three different pediatric clinics located in Sockcho. In this survey 40.4% of infants were breast-fed, while 44.1% of them were bottle-fed. Among subjects 75.9% of infants began to be weaned within 6 months. Among those who finished weaning aleady, 56.7% of infants fnished weaning 11 to 13 months. Sixty percent of mothers got the nutritional knowledge on infant feeding by the aid of cook book and child care book. Fruit juice was firstly introduced as infant food. The most favorite food for infants was fruit juices which were followed by soup, and e99 Pudding. Cereals were used frequently as infant foods while meat & fish, beans and vegetables were lesser used for infants. For the improvement of nutritional states of infants. nutritional education programmes and development of infant food is needed.

The heat perm is the preferred hair technique to get positive affects such as increase of work efficiency and sale in hair industry. The subjects of this study is 262 hair shop workers and it was investigated heat perm device using reason, using satisfaction and repurchase. As a result, the perm accounted for 32.1 and the use of digital perm devices was more than that of setting perm devices. The reasons for the use were that the longer the setting device was engaged, the flexible it was the hair wave. The higher the rank, the better the hair wave retention and the long hair treatment, and it also helped sales. (p<0.05) Digital perm device can be hair-wavy in the desired style while in use, and the longer the working period, the more advantageous. The repurchase intention was that the longer the period of service and the higher the rank, the more advantageous it was. (p<0.05) The reasons for the usage of setting perm and digital perm were correlated with the satisfaction of use and the repurchase intention. The reasons for the use were helpful for sales and elastic hair wave and long hair waving was possible, which affected the repurchase. In conclusion, heat perm had been found not only helped sales, made a good hair wave, and the long hair waving, but also to be preferred to the long working period of the hair shop and the rank above the designer.

1) A process was described for the preparation of drum-dried weaning food containing about 20% protein and based on a blend of sweet potato, full-fat soy flour, minerals, vitamins and methionine. 2) The protein efficiency ratio of this product was 2.63 as compared to 3.30 for the blend containing corn starch in place of sweet potato. This is attributed to the partial destruction of available lysine in the presence of sweet potato during the drum-drying process. 3) Overall nutritive value of the weaning food was comparable to milk food and control food based on corn starch and soy flour in terms of feed efficiency, body composition and protein retention.

전기 에너지가 우리 생활에 유용하게 사용되는 부분이 정말 많다. 최근에는 자전거 열풍이 불면서 덩달아 전동 자전거 업계에도 호황이 일고 있는데, 21C 기후 변화와 환경오염, 교통체증 등의 문제해결을 위한 저탄소 녹색성장의 인식 전환으로 전동 자전거 이용이 늘어나고 있다. 이는 전동 자전거도 전기 에너지가 사용되고 있다 점이다. 하지만 이런 장점을 가지고 있는 전동 자전거를 많은 사람들이 구입하지 못하는 이유가 있다. 대부분의 이유가 '집에 자전거 1대씩 가지고 있는데, 굳이 비싼 돈을 주고 전동 자전거를 구입해야하나?' 라는 생각을 가지게 된다. 또 다른 이유로는 기존의 전동 자전거가 탈 부착 형식이 아닌 일체형으로 나오기 때문에 다른 신제품의 전동 자전거가 나온다면 기존의 전동 자전거의 부품을 사용하지 못 하고 새로운 자전거를 사야 한다는 단점 때문이다. 따라서 본 논문에서는 탈 부착이 가능한 전기 자전거 시스템을 구현하고자 한다.

특정한 컨텐츠의 시작과 끝까지의 시간을 표시해주는 NPT는 디지털 방송에서 비데오와 데이터의 동기화된 서비스를 제공하기 위해서 뻐P에서 권고하는 규약이지만 널리 사용되고 있지는 않다 그 이유는 기술적, 문화적, 경제적인 요인 등이 있을 수 있는데 이 글에서는 기술적 원인에 대해서만 다룬다. 현재 사용되고 있는 수신기에 NPT 기능이 구현되어 있지 않다는 점과 구현되더라도 NPT스트림을 추가적으로 인코딩해야 하는 번거로움 그리고 그 와중에 생기는 동기화의 오차등이 NPT 사용을 막는 가장 큰 기술적 원인들이다. 이런 상황에서 MPT를 사용하는 방법을 몇몇 논문에서 제시했지만, 여전히 실제 방송 프로그램에 사용하기엔 미진한 점이 남아 있다. 그 이유는 동기화의 정확성이 검증되지 않은 점 , 추가적인 대역폭 사용이 필요한 점등으로 들 수 있는데 이 글에서는 그 문제점들에 대해서 고찰해본다 또한 그를 통해서 현재 사용하고 있는 방법의 근원적인 결함을 지적하고 새로운 방법인 EIT 테이블을 이용하는 방법과 그 가능성에 대해서 생각해본다.

지금 우리가 고민해 보아야 하는 것은 여름 출하를 앞둔 자돈에게 무엇을 어떻게 줄 것인가 이다. 우선은 자돈의 성장율을 급격하게 감소시키는 소모성 질병에 감염되지 않도록 습도 관리가 매우 중요하며, 또한 이유 스트레스에 따른 이유 후 성장정체 현상을 최소화하기 위하여 소화율이 높은 원료가 사용된 사료 급여가 필수적이라 할 수 있다.

Mixing characteristics of unlike impinging streams double injectors have a great effect on combustion stability and combustion efficiency for liquid rocket engine. In this study a cold test was carried out, using water and TCE as simulants, in order to examine the effect of design parameters such as impingement angle, orifice diameter ratio and momentum ratio on the mass distribution and mixing quality.

Recently, as the non-face-to-face environment has developed due to COVID-19 and environmental pollution, the importance of online digital healthcare is increasing, and venture start-ups and activities such as health care, telemedicine, and digital treatments are also actively underway. This study conducted the impact on the acceptability of digital healthcare smartwatches with an integrated approach of the expanded integrated technology acceptance model (UTAUT2) and the behavioral inference model (BRT). The most advanced integrated technology acceptance model for innovative technology acceptance research was used to identify major factors such as utility expectations, social effects, convenience, price barriers, lack of alternatives, and behavioral intentions. For the study, about 410 responses from ordinary people in their teens to 60s across the country were collected, and based on this, the hypothesis was verified using structural equations after testing reliability and validity of the data. SPSS 23 and AMOS 23 were used for research analysis. Studies have shown that personal innovation has a significant impact on the reasons for acceptance (use value, social impact, convenience of use), attitude, and non-use (price barriers, lack of alternatives, and barriers to use). These results are the same as the results of previous studies that confirmed the influence of the main value of innovative ICT on user acceptance intention. In addition, the reason for acceptance had a significant effect on attitude, but the effect of the reason for non-acceptance was not significant. It can be analyzed that consumers are interested in new ICT products and new services, but purchase them more carefully and selectively. This study has evolved from the acceptance analysis of general-purpose consumer innovation technology to the acceptance analysis of consumer value in smartwatch digital healthcare, which is a new and important area in the future. Industrially, it can contribute to the product's purchase and marketing. It is hoped that this study will contribute to increasing research in the digital healthcare sector, which will play an important role in our lives in the future, and that it will develop into in-depth factors that are more suitable for consumer value through integrated approach models and integrated analysis of consumer acceptance and non-acceptance.
