Sense of community and length of residence are important variables influencing community participation. The study aims to identify the factors influencing community participation on sense of community. Particularly, the study examine the moderating effects on the length of residency between sense of community and community participation. Data were collected from 130 usable questionnaires among residents of rural villages. Results of a factor analysis yielded three dimensions of sense of community which are solidarity, belonging, and emotional intimacy. Results show that all of factors among three dimensions of sense of community have significance for community participation. And length of residency has a positive effects as a moderator between community capacity and community satisfaction. Results also indicated that length of residence has an negative interactional effects with moderator. It means that even though higher belonging, less community participation if people live in longer their community. It was suggested that sense of community and length of residency should be considered in rural community development policy.

Silica(SiO2) nanoparticles are used as additives in plastics and rubbers to improve mechanical, electrical, magnetic properties and optical material. Silica nanoparticles were synthesized by the gas phase thermal oxidation of several kinds of precursors in many types of reactor. Diffusion flame reactor has some advantages compared with other types of reactors. In this study, we investigated the generation of silica nanoparticles on the effect of residence time by tetraethylothosilicate(TEOS) in a turbulent diffusion flame reactor controlled by providing reactant flowrate and reactor geometry affect particle morphology, particle size and particle size distribution. To determine the flame residence time, flame length should be determined which was examined by ICCD image. Particle size, distribution and morphology were performed with TEM.

This study conducted qualitative research through in-depth interviews on the diffusion process of Korean food in accordance with the length of residence of Chinese students in Korea. As the analysis method, the qualitative analysis method such as NVivo12.0 was used, and the analysis was performed through word frequency, word cloud, and coding matrix. The images of taste of Korean food were revealed as 'Spicy', 'Sweet', and 'Light taste' by both short-term Chinese residents and long-term Chinese residents. The long-term Chinese residents showed their dissatisfaction with the institutional food, and they also pointed out the importance of the matter of cooking for quick adaptation to life in Korea. The long-term Chinese residents also thought of Korean food as 'High-fiber food', and this was influenced by the 'Less-oil' cooking method of Korean food, which is different from the cooking method of Chinese food. The length of residence was used as a main variable of this study, and it was one of the factors having positive effects on the diffusion of Korean food and acculturation. It would be difficult to generalize the results because this study used the convenience sampling method and snowball sampling.

본 연구는 광주지역에 거주하는 결혼이주여성 83명을 대상으로 일반적 특성, 신체 계측 및 혈압측정, 식품 및 영양소 섭취량을 조사하여 결혼이주 여성의 영양섭취상태 및 건강 관련 요인을 파악하기 위해 수행되었다. 연구대상자의 평균연령은 31세였으며 한국 평균거주기간은 5.3년이었고 연령 분포는 20~29세가 40명 (48.2%), 30~49세가 43명 (51.8%) 이었다. 조사대상자의 평균체중은 53.7 kg, 평균 신장은 156.3 cm 였으며, 거주기간이 5년 이상인 그룹이 5년 미만인 그룹에 비해 체중, BMI, 체지방률, 이완기 혈압 등이 유의적으로 높았다. 24시간 회상법을 통해 식품군 섭취량을 분석한 결과 20~29세 그룹에 비해 30~49세 그룹의 채소류 섭취량이 유의적으로 높았으나, 국민건강영양조사에 의한 같은 연령대의 우리나라 여성과 비교하면 과일류, 육류, 당류 섭취량이 낮고 계란류, 어패류, 우유 및 유제품류의 섭취량이 높은 편이었다. 영양소 섭취상태를 살펴보면 총 에너지섭취량은 1,641.0 kcal였으며 20대 조사대상자의 85.0%가 에너지필요 추정량 이하로 에너지를 섭취하였으며, 30~40대의 76.7%가 에너지필요추정량 이하로 섭취하였고, 칼슘, 아연, 비타민 A, 비타민 $B_6$, 비타민 C, 엽산 등은 조사대상자의 50% 이상이 평균필요량 미만으로 섭취하였다. 20대 그룹에 비해 30~40대 그룹이 비만한 경향을 나타냈으나 식품섭취량에 차이가 없었으며, 오히려 채소 섭취량이 유의적으로 많았으며 식생활과의 관련성이 적었다. 조사대상자를 거주기간으로 구분하여 비교하면 거주기간이 5년 이하인 그룹이 5년 이상 거주 그룹에 비해 콜레스테롤의 섭취량이 유의적으로 높았으며, 콜레스테롤 섭취량이 계란이나 우유와 상관관계가 있는 것으로 조사되었다. 본 연구대상자의 평균 연령은 30세로 비교적 젊고 건강하여 한국 이주 후의 식생활 변화에 의한 건강상의 변화에 큰 영향이 나타나지는 않은 것으로 생각된다. 우리나라 결혼이주여성의 영양섭취상태는 사회 경제적 여건 등과 같은 다양한 요인에 의해 영향을 받기 때문에 결혼이주 여성의 올바른 식생활 정착 및 다양하고 경제적이며 건강한 식품선택을 위한 교육이 필요함을 알 수 있었다. 특히 결혼 이주 여성의 식생활에 영향을 미치는 다양한 요인에 대응할 수 있는 맞춤형 교육이 필요하며, 인터넷 등의 교육매체를 적극 활용해야 될 것으로 생각된다. 주부의 건강한 식품선택과 올바른 영양관리는 가족전체의 식품섭취와 영양상태에 직접 영향을 미치며 건강한 사회의 초석이 되므로 결혼이주여성에 대한 장기적이고 적극적인 영양교육이 필요하다.

This study was conducted to investigate the dietary adaptation and use of the university foodservice (UF) in Korea according to the residence period of foreign students. The average length of residence in Korea of t he subjects was 8.2 months. The period of residence was divided into quartiles: 1-4 months in the first quartile (average 2.2 months), 5-7 months in the second quartile (average 6.3 months), 8 months in the third quartile, and 9-66 months in the fourth quartile (average 18.3 months). The regularity of meals tended to be the highest in the 1st quartile and lowest in the 2nd quartile and then increased in the 3rd and 4th quartiles. The frequency of consumption of delivery food and convenience store food was lowest in the first quartile and highest in the second quartile and then decreased with the period of residence. The frequency of night eating increased according to the period of residence after the second quartile. The degree of adaptation to Korean foods was highest in the first quartile. The use of the university cafeteria was significantly higher in the 1st and 4th quartiles than in the 2nd and 3rd quartiles (p<0.05, p<0.01, respectively). The satisfaction with the UF decreased as the residence period increased. Based on these results, since international students are very positive and try to adapt to the dietary life in Korea in their early years of studying in Korea, it would be desirable to intensively support them to adjust to their dietary life at this time. In addition, since it takes about 18 months or more to assimilate the Korean food culture and show positive changes, it is necessary to continuously operate the Korean food culture adaptation program for international students over this period.

An integrated adsorption/catalytic process has been considered to treat dioxin and $NO_x$ simultaneously. The process consists of a cyclone and a reactor with nine bag filters. In this study, numerical analysis has been performed to understand flow characteristics with inflow-duct types in the reactor. To consider flue gas and activated carbon particles simultaneously, Euler-Lagrangian model was employed. Fundamental flow patterns of flue gas and activated carbon particles, pressure distribution and distribution of activated carbon have been obtained from the numerical analysis. Also trace length and residence time of flue gas, residence time of activated carbon particles have been calculated directly. Flow patterns of flue gas and activated carbon particles in the reactor were very complicated and they moved along very various paths. Therefore, their residence time in the reactor was also various. The flow characteristics in the reactor were strongly influenced by inflow-duct types. The results obtained would be effectively used to estimate the removal efficiency in the reactor once the residence time is combined with the reaction equation.

본 연구에서는 유효수직응력의 영향을 받고 있으며, 공간적으로 상관된 간극분포를 포함하고 있는 단일 균열 내에서의 용질이동에 대한 공간적 거동을 수치적으로 분석하였다. 분석결과 단일 균열에서의 용질이동은 간극분포의 공간적 상관정도와 적용된 유효수직응력에 크게 영향을 받는 것으로 나타났다. 공간적 상관길이가 증가함에 따라 용질입자의 평균이동시간은 감소하였으며, 또한 용질이동에 대한 굴곡도와 Peclet 수(유체흐름에 의한 용질의 이송율과 분자확산율과의 관계를 나타내는 무차원 수)가 감소하는 경향을 나타내었다. 이는 공간적 상관길이가 증가할수록 단일 균열 내의 간극분포가 용질입자의 이동에 유리하다는 것을 의미한다. 그러나 유효수직응력이 증가할수록 용질입자의 평균이동시간과 굴곡도는 증가하는 경향을 나타냈으며, Peclet 수는 감소하는 경향을 나타냈다. 이는 유효수직응력이 증가할수록 접촉면의 증가로 인해 한 두 개의 상대적으로 큰 국부유량을 가지는 유로를 따라 이동하기 때문인 것으로 판단된다. 또한 본 연구에서 용질이동에 대한 모의된 결과에 근거하여 공간적 상관길이에 따른 유효수직응력과 용질의 평균이동시간과의 관계를 나타내는 지수형태의 상관식을 제안하였다.
