This study, a sub-one of comprehensive research work titled under "A Evaluation System of Amenity / Disamenity Elements in Rural Villages", tried to propose a rational methodology for development of rating tabulation for evaluation of amenity / disamenity elements in rural villages. The system developed in the study has the formalized rating grades between 2 and 5 for convenience/simplification of analysis work. For each evaluation element in the lowest order of the system, 5 types of rating technique were arranged, which were based on statistical analysis using mean and standard deviation values, its existence or not, relative significance of its holding volume and quality, synthesized weight scale of its quality and quantity, and the others. And, standardized 4-steps procedure for rating tabulation was proposed. Finally, through case studies of 4 sample villages representing the flat-plain, upland, seashore and periurban rural areas, the applicability of this rating tabulation system was verified.

Usually, amenity elements coexist with disamenity elements in rural villages. Through the literature reviews and group discussion of participant research staffs in this study, a tentative classification system of amenity and disamenity elements was pro-posed with 4-tier hierachial order; for amenity, 3-7-29-76(numbers of the high, medium to low categories and elements) and 3-6-16-32 for disamenity. finally, through case studies of 4 sample villages representing the flat-plan, upland, seashore and periurban rural areas, the applicability of this classification system was verified.

This study examines whether the reinforcement theory would be effectively applied to teaching assistant robots between a robot and a student in the same way as it is applied to teaching methods between a teacher and a student. Participants interact with a teaching assistant robot in a 3 (types of robots: positive reinforcement vs. negative reinforcement vs. both reinforcements) by 2 (types of participants: honor students vs. backward students), within-subject experiment. Three different types of robots, such as ‘Ching-chan-ee’ which gives ‘positive reinforcement’, ‘Um-bul-ee’ which gives ‘negative reinforcement’, and ‘Sang-bul-ee’ which gives both ‘positive and negative reinforcement’ are designed based on the reinforcement theory and the token reinforcement system. Participants’ task performance and reaction rate are measured according to the types of robots and the types of participants. In task performance, the negative reinforcement robot is more effective than the other two types, but regarding the number of stimulus, the less the stimulus is, the more effective the task performance is. Also, participants showed the highest reaction rate on the negative reinforcement robot which implies that the negative reinforcement robot is most effective to motivate students. The findings demonstrate that the participants perceive the teaching assistant robot not as a toy but as a teaching assistant and the reinforcement interaction is important and effective for teaching assistant robots to motivate students. The results of this study can be implicated as an effective guideline to interaction design of teaching assistant robots.

The purpose of this study was to examine the effectiveness of an empowerment program, using horticultural therapy among the elderly clients of an In-Home Service Center at a Community Social Welfare Center. The empowerment program applied in this study included group horticultural activities, garden activities, home horticultural activities, selling the products and a self-help group. This program had 49 sessions in total and was held from April 2004 to February 2005. The results of this research are as follows. According to the results of the pre-, mid-term, and post-test, there were significant improvements among the subjects who participated in the horticultural therapy program, especially in terms of intrapersonal empowerment, and interpersonal empowerment of self-esteem of the elderly using In-Home Services. Through using those common and familiar sources of horticultural materials, what the elderly found is the fact that they have the ability to create and raise plants of their own and to utilize this ability in their lives. Thus, it can be said that horticultural therapy program is helpful to empower the elderly in terms of developing their potentials in productivity and encourages them to utilize and maintain their horticultural skills and productivity in their lives.

흑운모 편마암과 화강암에 대한 풍화정도에 따른 광물조성과 화학성분 변화를 X-선회절분석, 전암분석을 통하여 연구하였다. 흑운모 편마암의 주 구성광물은 흑운모, 석영, 사장석이며 화강암의 주 구성광물은 석영, 사장석, 백운모과 약간의 정장석을 포함하고 있다. 풍화가 진행될수록 흑운모 편마암은 버미큘라이트와 할로이사이트가 증가하고 화강암은 일라이트와 캐올리나이트가 증가한다. 풍화가 진행될수록 대체로 Na2O, CaO, K2O가 감소하고 Al2O3의 함량이 증가하지만, Fe2O3의 값은 흑운모 편마암과 화강암에서 큰 차이를 나타낸다.

순무는 초음파 병행 추출을 통하여 60, 100℃에서 모두 추출 수율을 증가시킬 수 있음을 확인하였다. 알코올 분해 효소인 ADH와 Aldehyde 분해 효소인 ALDH의 분해 활성 측정 실험을 통해 순무의 추출물들은 물 일반 추출물보다 초음파 병해 추출물들이 높은 활성을 나타내는 것을 확인하였고 특히 ADH의 활성율 보다 ALDH의 활성이 높게 나타나 알코을 분해 과정의 최종 목적지인 acetic acid와 이산화탄소로의 분해에 순무의 추출물들이 유의적인 활성을 나타내고 있음을 확인할 수 있었다. 60℃ 열수 추출물은 100℃ 열수 추출물과 비교하여 관능평가 시 높은 점수를 얻었으며 이의 추출물들은 감압농축을 통해 이취의 제거가 이루어져 열수추출 시 유용한 방법으로 평가되었다.

The purpose of the study is to explore whether input enhancement as a subtype of FonF can be proven feasible and productive as part of normal classroom work and whether it can assist in learners` long-term progress in English. 80 freshmen who enrolled general English at a Korean university were divided into an experimental group and a control group and read the text in one of two conditions: no enhancement, relative-clause enhancement. The results demonstrated the translation task scores obviously showed the effect of input enhancement. The enhanced text of relative-clause led to learning relative-clause as a target linguistic structure. Second, the effect of relative-clause enhancement text was significant on reading comprehension test as well as on translation task. The interesting result was that the effects on relative-clause learning and reading comprehension were retained in the follow-up posttest conducted four weeks later. The study proposed that learners` linguistic developmental system have been affected by the enhanced relative-clause text generated by learners` need and that their interlanguage system be reconstructed.

In recent years, many researches are actively undertaken for environmental-friendly animal production according to the increased understanding about food safety because of the outbreak of various diseases such as mad cow disease, Foot and mouth disease and Poultry Influenza virus. However, high quality(higher safety)-animal production may not be successful without increasing of disease resistance of animal and the improvement of feeding environment. To increase the disease resistance is able to be accomplished by stimulating the immune function. The present study was undertaken to investigate the effects of enzyme mixture reinforced with β-glucanase activity which degrade polysaccharide to release β-glucan known as stimulator of immune function on the change of milk production and somatic cell count. After 12weeks of experimental feeding, milk production tended to be increased and somatic cell count was decreased from average 227×10⁴ to 37.1×10⁴. Milk protein and solid-fat content were tended to increase but milk fat showed decreasing tendency by the feeding of enzyme mixture. All together, it has been suggested that the improvement of high quality milk production may be possible through the dietary addition of immune modulating enzyme mixture in lactating dairy cows.

In recent years, the consumption of livestock products were markedly decreased by awareness of world-widely occurred diseases including mad cow disease, Foot and mouth disease, Hog cholera, and Poultry Influenza virus. The consumers are also wanting to have highly safe food such as organic animal products because of concerning about residual of antibiotics in animal products. However, disease control and impairment of productivity are the major problem in organic animal production. On these points of view, the present study was undertaken to investigate the effects of 1% or 2% of dietary probiotics fortified with various minerals on improvement of egg production and egg quality in old layer feeding low quality feed mainly composed of food waste, sesame meal, and rice bran. After 4 weeks of experimental feeding, the diameter of spreading of egg white was clearly decreased from 11.2cm of control eggs to 10.5m and 10.1m in 1% and 2% treatment group eggs, respectively. The color of egg yolk was 9.3 in control eggs but remarkably increased in treatment groups showing 10.1~10.2. Egg production was 75.8% in control layers but significantly increased to 79.8% of 1% treatment group and 82.9% of 2% treatment group layers. Egg weights (C : 66.3g, 1% : 73.2g, and 2% : 76.7g) and egg shell thickness (C : 0.33㎜, 1% : 0.35㎜ and 2% : 0.36㎜) were also increased by the addition of 1% or 2% of probiotics when compared to those of control group eggs. All together, it has been suggested that dietary addition of probiotics fortified with various minerals can improve the egg quality and egg production in layer"s productivities by the recycling of organic waste resources such as food waste and agricultural by-products.

최근 10여년 동안 운동과학에 대한 다량의 문헌들에도 불구하고 여성들을 대상으로 운동지속(exercise adherence)과 운동효과에 대한 연구들은 많지 않다. 이 연구의 목적은 강화방법이 여성의 운동지속과 건강에 미치는 영향을 규명하기 위한 것이었다. 생활체육으로 에어로빅댄스를 하고자 방문한 31명의 중년여성들이 자신들이 원하는 세 개의 다론 시간대의 수업에 각각 등록을 하였다. 각 교실은 체지방 측정치로 피드백을 제공받는 집단(n=10), 출석이 양호할 시 에어로빅무용복을 보상받는 집단(n=11), 그리고 통제 집단(n=10)이 되어 실험에 참가하였다. 피험자들을 같은 강사의 지도로 하루에 45분, 주 5회(월-금), 8주 동안 에어로빅댄스를 실시하였다. 일원변량분석 결과 체지방으로 피드백을 제공받으며 운동한 집단은 다른 두 집단에 비해 높은 출석률을 보였다(p<.05). 공변량분석(ANCOVA)에서는 피드백 집단이 통제 집단보다 체지방율과 POMS의 총정서장애(Total mood disturbance)에서 유의하게 낮은 수치를 보였다(p<.05). 안면피부상태에서는 집단 간에 유의한 차이를 보이지 않았지만, 집단을 합한 운동 전·후간에는 차이가 있게 나타났다(p<.05). 이 연구는 생활체육 현장에서 피드백을 제공하여 강화를 시키면 중년여성들의 운동지속(exercise adherence)을 높일 수 있고 건강 증진에도 효과적이라는 결론에 도달하였다. 그 외 연구결과를 토대로 운동지속을 높이는 관점에서 논의가 이루어지고 장래연구를 위한 방향도 제시되었다.
