  • 색 오버레이는 난독증을 완화시키는 보조도구로 사용되어 왔다. 최근에 컴퓨터에서 사용할 수 있는 몇 종의 가상 색 오버레이가 개발되었다. 기존의 가상 색 오버레이는 색상이 제한되어 최적의 색상 선택을 할 수 없고, 오버레이 창과 겹쳐지는 다른 창을 제어하기가 어려운 문제점이 있으며, 색상이 제품마다 조금씩 다르며, 그 값이 정확히 공개되지 않아 구현상에 어려운 점이 있다. 본 논문에서는 키보드 후킹과 트레이 아이콘을 통해 가상 색 오버레이를 이동시키지 않고 겹쳐진 창을 제어할 수 있는 가상 색 오버레이를 구현하였다. 분광측색계를 이용하여 필름 오버레이의 색도 정보와 투과율을 측정하여 가상 색 오버레이에 적용할 색상 정보를 추정하는 방법을 제안하였고, 오버레이 색상을 좀 더 세분하여 구현하였다. 시험 결과 기존의 가상 오버레이의 문제점이 모두 해결되었다. 따라서 WRRT의 진단 결과를 컴퓨터에서 그대로 이용할 수 있다.

  • The purpose of this study was to analyze the status of school foodservice facilities, utilities and equipment & sanitary education in provinces, This study was carried out from September 2008 until December 2008 and is targeted towards schools' dietitians that work at schools with school foodservice. 1,623 schools participated in this research and Kangwondo, Choongchungdo including the metropolitan area with frequent occurrence of food bone disease were the targets of this research. The regional distribution of this research is as follows; 377 schools in Seoul, 648 schools in Gyeonggido, 160 schools in Kangwondo, 438 schools in Choongchungdo equaling 1,623 schools in total. And out of the total 1,623 schools, 815 (50.2%) were elementary schools and 808 (48.8%) were middle and high schools (p < 0.001). Most of the elementary schools, excluding 4 schools, were self-operated. In the case with middle and high schools, 81.5% (513 schools) were self-operated and 18.4% (295 schools) were contracted. When dealing with the sanitation management of school foodservice in Kangwondo and Seoul, elementary schools were less equipped with equipment and facilities than middle and high schools which proved that they were in need of improvements (p < 0.01). Schools with self-operated foodservice, in particular, were in need of preparation zone improvements. 52.3%~88.0% of stainless equipment such as utensils, spoons/chopsticks, subsidiary food tray, and food trays were sterilized by dryers. Work tables, vegetable slicers, and mincers were chemically sterilized and plastic materials were sterilized by ultraviolet rays. Data from newspapers, Internet and TV are collected beforehand and then an annual hygiene educations plan for employees are put together. Hygiene education for employees are carried out monthly through oral method.

  • The objectives of this study were to analyze the factors that affect the productivity for university food services. In a survey involving four-year university dining centers throughout the country, and correlations among thriteen different variables that affect productivity were determined. Productivity index (PI) was determined by meals per hour, the average score for 38 institutions was found to be 14.2 meals/hour. For serving methods, the fixed ration had a higher PI than the self-serving. When two types of serving trays were considered, the PI of the compartmantalized trays was higher than that of the tray accompanying saparate small dishes. When single (S)-or. multiple(M)-menu was compared with the cafeteria style, a higher PI was obtained by the S-or M-menu. Among the three operation systems, the PI was found to be the highest by direct operation (17.6 meals/hour), followed by contract operation (11.1 meals/hour) and rent operation (7.9 meals/hour). For the factors that affect the productivity of the university food services, the total number sewed (r=0.54, p<0.001) and the use of convenient food items (r=0.28, P<0.05) exhibited positive correlations, while food costs and labor costs showed negative correlations. This suggests that the productivity of university food service increases as the total number served and the use of convenient food item increased, but decreases as the food costs and labor costs per meal increased. A regression analysis showed that three variables - total number sewed, labor cost per meal, number of employees-influenced about 73% components of food service showed a negative correlation with PI and a positive correlation with the labor cost per meal.

  • 추잠기의 적엽이 익춘의 불발아와 접목의 활착에 미치는 영향을 조사하여 다음과 같은 결과를 얻었다. (1) 추잠기의 적엽은 익춘의 불발아비율을 증대시키는 원인이 되며 특히 전적엽을 하면 적엽을 하지 않은 것에 비하여 불발아비율이 46%나 증대한다. 그리고 동일한 기조에서 일부분의 엽을 여러가지 방법로 적채하였을 경우에 있어서도 적엽을 한 부분의 불발아율이 적을 하지 않은 부분의 그것 보다 크다. (2) 추잠기의 적엽은 익춘에 그 동아를 일아근접하였을 때에 있어서 그 활착비율을 크게 저하하며 동일지조에 있어서 여러가지 방법으로 적엽을 하였을 경우에 있어서도 적엽을 한부분의 동아의 활착이 적엽을 하지 않은 부분의 보다 항상 좋지 않다. (3) 추잠기에 적엽을 하면 익춘잠기의 수량을 7∼20% 저하시키며 특히 기조의 하반부적엽(20%)과 전적엽구(12%)가 그 정도가 심하다.

  • Fruits we subjected to complex dynamic stresses in the transportation environment. During a long journey from the production area to markets, there is always some degree of vibration present. Vibration inputs are transmitted from the vehicle through the packaging to the fruit. Inside, these cause sustained bouncing of fruits against each other and container wall. These steady state vibration input may cause serious fruit injury, and this damage is particularly severe whenever the fruit inside the package is free to bounce, and is vibrated at its resonant frequency. The determination of the resonant frequencies of the fruit may help the packaging designer to determine the proper packaging system providing adequate protection for the fruit, and to understand the complex interaction between the components of fruit when they relate to expected transportation vibration inputs. The vibration characteristics of the pears in corrugated fiberboard container in transit were analyzed using FEM (finite element method) modeling, and the FEM modeling approach was first validated by comparing the results obtained from simulation and experiment for the pear in the frequency range 3 to 150 Hz and acceleration level of 0.25 G-rms and it was found that between simulated and measured frequencies of the pears have a relatively good agreement. It was observed that the fruit and vegetables in corrugated fiberboard container could be analyzed by finite element method. As the elastic modulus of the cushion materials of corrugated fiberboard pad and tray cup decreased, the first frequencies of upper and lower pears increased and the peak acceleration decreased.

  • In mass production of seed-potato plantlets, the processes for in vitro propagation and ex vitro acclimatization with a high cost should be improved by a culture system with environmental control using scaled-up culture vessels. The experiment was conducted to design a hydroponic culture system for enhancement of growth and development of seed-potato (Solanum tuberosum) plantlets cultured under photoautotrophic (without sugar in culture medium) conditions with controlled light intensity and ventilation rate. The culture system was consisted of scaled-up culture vessels, ventilation pipes, a multi-cell tray and an environmental control system (ECS) for optimum controlling in temperature, light intensity, ventilation rate, and culture-medium supply. Growth and development of the plantlets was significantly increased under the ECS compared with a conventional culture system (CCS) of photomixotrophic culture (with sugar in culture medium) using small scale vessels. For 21 days, leaf area of the plantlets was expanded more than 2 times, and number of internodes also approximately 4 times greate. under the ECS. In addition, the photoautotrophic growth in sweetpotato (Ipomoea batatas) and chrysanthemum (Chrysanthemum morifolium) plantlets was greater more than 2 times compared with the CCS.

  • The purpose of this study was examining the effects of family sandplay therapy with structural family therapy in improving the family strengths of children with emotional and behavioral disorders. First, we looked for a way to combine family sandplay therapy with structural family therapy and formulated an approach that could maximize the strengths of each theory and complement each other's weaknesses. And then we applied family sandplay therapy together with structural family therapy and analyzed its effects on family strengths. The subjects of this study were 10 families of children with emotional and behavioral disorders, and they were divided into an experimental group with 5 families and a control group with the other 5. To the experimental group received 16 sessions of family sandplay therapy with structural family therapy. In order to prove the effectiveness of family sandplay therapy with structural family therapy on family strengths, a family relationship( husband-wife relationship, parent-child relationship, and sibling relationship) scale and a family function(family cohesion, family adaptability) scale were used. The main findings of this study are as follows. First, the family relationships of the families with emotional-behavioral disorder children were improved after the application of family sandplay therapy with structural family therapy. Second, the application of family sandplay therapy with structural family therapy improved the family function of families with emotional-behavioral disorder children. Third, in the course of family sandplay therapy with structural family therapy, family sand tray was changed in a pro-healing direction, and family structure was also transformed from a dysfunctional structure to a functional one. As previously stated, family sandplay therapy with structural family therapy for families of children with emotional and behavioral disorders enhanced family strengths through improving family relationships and restoring family functions.
