본 논문에서는 화자식별을 위한 특징벡터의 새로운 클러스터링 방법을 제안한다. 제안된 방법은 클러스터 센터에 대한 초기값 설정과 클러스터 개수에 대한 사전 정보 없이 클러스터링이 가능하다. 각 클러스터 센터는 경계 차감 클러스터링 알고리즘으로 한 번에 한 개의 클러스터 센터가 추가됨으로써 순차적으로 구해지며, 클러스터 개수는 클러스터간의 상호관계를 조사하여 결정된다. 인공 생성 데이터 및 TIMIT 음성을 이용하여 실험한 결과로부터 제안된 방법이 기존의 방법보다 우수함을 확인하였다. In this paper we propose a new clustering algorithm that performs clustering the feature vectors for the speaker identification. Unlike typical clustering approaches, the proposed method performs the clustering without the initial guesses of locations of the cluster centers and a priori information about the number of clusters. Cluster centers are obtained incrementally by adding one cluster center at a time through the boundary subtractive clustering algorithm. The number of clusters is obtained from investigating the mutual relationship between clusters. The experimental results for artificial datum and TIMIT DB show the effectiveness of the proposed algorithm as compared with the conventional methods.

The purpose of this research was to provide basic educational data on the proper eating habits of children who use the community children center. The results of the research conducted by polling the fourth, fifth, and sixth-grade children of the community children centers are summarized as follows. Male children had more meals and ate them faster than those of female children, and they also tended to watch more TV and read books. Moreover, children of families headed by fathers ate until they were full, whereas children of households headed by mothers ate less. More female than male children skipped breakfast, and the percentage of children who had their meals alone was high among children reared by their grandfathers. Most of the children ate only what they liked. Moreover, male children ate only particular fruits and vegetables, whereas female children ate only beans and miscellaneous cereals. Most of the children recognized that they had eating problems, such as eating only what they liked and eating meals on irregular schedules. Such eating habits were affected mainly by family members such as parents, brothers, and sisters. Female children scored higher than male children in terms of nutrition and hygiene knowledge. Approximately 40~50.3% of all subjects became interested in nutrition and hygiene education at the community children center. Most of the children recognized that nutrition and hygiene education is necessary at the community children center. They also recognized their own eating problems and wanted nutrition and hygiene education to be taught at the community children center. Accordingly, regular educational activities and meals for children in the community children center considered a children`s particular home background to improve eating habits in the children.

가정간편식(HMR) 시장의 현황과 해결방안 연구

이윤정(Lee, Yun-Jung),김윤경(Kim, Youn-Kyeong),윤예리(Youn, Aye-Ree) 한국외식경영학회 2021 외식경영연구 Vol.24 No.5

최근 식품･외식산업에서 가장 급속하게 성장·분화하고 있는 영역은 바로 가정간편식(HMR, Home Meal Replacement)이다. 선행 연구논문을 바탕으로 문헌연구를 진행하며 각종 정책자료 등을 객관적으로 분석·평가하고, 식품·외식산업 관련 통계자료를 활용하여 HMR의 현황과 이슈 그리고 문제점을 파악하여 해결방안을 모색하고자 하였다. HMR이 부상하게 된 기반에는 네트워크와 공유경제의 확산, 산업과 시장에서의 스마트화, 코로나-19 등 새로운 환경이 조성된 점과 식품･외식산업 간 융합의 가속화 등 푸드테크(Food Tech), 밀키트의 확대, 케어푸드(Carefood)로의 분화 등이 주요 이유이다. 이러한 HMR 시장의 확대와 더불어 여러 가지 문제점이 나타나고 있다. 우선 포장과 저장, 가공기술을 위한 R&D와 소수 생산 대기업의 독과점, 납품 유통업체의 불공정 관행, 관련 전문인력 양성과 안정적 원료수급 확보의 어려움 등이다. 따라서 HMR 관련 공정한 정부정책이 필요하다. 또한 HMR 상품은 대부분 1회용 식품 용기･포장인데, 이것의 감소 방안과 재활용 및 친환경 포장재의 활용률을 높이는 환경보호 방안이 마련되어야 한다. HMR의 급속한 성장에 따른 보건·안전관리의 강화와 소비자 보호를 위한 대책 마련도 시급한 과제이다. 온라인유통 식품 관련해서는 제조와 포장, 배송과 배송 종사자 관련 안전관리기준을 마련하는 것이 필요하다. 동시에 식품안전 사고 예방과 식중독 등 식품안전사고 발생 시 소비자를 보호할 수 있는 방안을 적극적으로 마련해야 한다. 음식·식품산업과 4차 산업혁명 시대의 만남인 푸드테크 시장에서 새로운 과제로 부상하고 있는 분야가 바로 대체식품 개척이다. HMR은 온라인을 통한 유통이 대부분이기 때문에 이에 대한 법적 근거와 관리방안 마련도 필요하다. 이러한 문제점들이 해결된다면 HMR의 활성화는 새로운 고용과 일자리를 창출하는 것은 물론 창업의 활성화에도 기여할 수 있을 것이라고 기대한다. The most rapidly growing and differentiated area in the recent foodservice industry is HMR(Home Meal Replacement). The basis for the rise of HMR is the spread of networks and the sharing economy, smartization in industries and markets, the creation of new environments such as COVID-19, and the acceleration of convergence between food and foodservice industries. The main reasons are the expansion of kits and differentiation into Carefood. Along with the expansion of the HMR market, various problems are appearing. First of all, R&D for packaging, storage, and processing technology, monopoly of a small number of large companies, unfair practices of suppliers and distributors, and difficulties in nurturing related experts and securing stable raw material supply. Therefore, fair government policies related to HMR are necessary. In addition, environmental protection measures that increase the utilization rate of recycling and eco-friendly packaging materials should be prepared. Also necessary to strengthen health and safety management and prepare measures to protect consumers. If these problems are resolved, it is expected that the revitalization of HMR will create new jobs and jobs and contribute to the revitalization of start-ups.

The inspiration and its application in fashion design is considered as one of the important factors in boosting the fashion arena. Many inspirations are adapted in fashion design and they make the fashion design unique and characteristic. In this study many fashion designs are analized to find what kind of inspirations were adapted and utilized for the fashion design in reality. The nature, historic costumes, ethnic costumes, art, sciences, literature, music, sports were revealed as the sources of fashion inspiration. The concerns on the environments, movies and dramas could provid inpirations in fashion as well. Several contents or steps were studied to provide the one of the examples of applications as follows : 1. The works of Marc Chagall were ananlized to fugure out and several plastic characteristics from his works were revealed such as fantastic strong colors, unreal animal patterns or their details, his wife and friends, various divisions of the surface and so on. These attirbutes had been favored in depiction of his works to express his home town or nostalgia. 2. `90s fashion desings inspired by the works of Chagall were analized to find out the methodology or the process of designs. The same Chagall colors were used in design and similar patterns were expressed through beaded work or printing jobs. The surface designs such as printing were the most prefered method in adapting the inspirations. 3. The plastic characteristics of the work of Chagall were attempted in clothing design and construction. The color combination, patterns which remind the animals, the surface divisions were used in design to practice the methodologies.

The change of heating load for domestic residential buildings was analyzed in this study. For this purpose, the change of heat transmission coefficient was studied and the heating load was calculated. Although the heating load in domestic residential buildings has been reduced, these circumstances have not been applied to floor heating panel design. In this study, the reasonable design of a heating panel based on an analysis of relation between heat output and design factors of a heating panel was suggested. According to the results, considering the actual heating load, a wider pipe pitch, a smaller pipe size, and a lower water temperature than those at present could be applied to the heating panels of residential buildings.
