  • In order to investigate the effect of feeding live yeast culture on the performance of laying hens, a feeding trial was conducted with 96 20-wk-old Hy4ine brown layers during their laying period of 60 wk. The live yeast culture used was a product from Saccharomyces cerevisiae that was cultured on the corn-based substrate followed by careful drying of whole material not to lose the viability of yeast. Three levels of yeast culture as 0.5, 1.0, and 2.0% for three treatments and 0% for the control were included in the experimental diets. The feeding trial was carried out for 60 wk from August 26, 1992 to October 26, 1993. To evaluate the performance of layers during cold or hot periods as affected by the yeast culture feeding, data from the 12-wk winter period and 12-wk summer period were separated and analyzed accordingly. During 60 wk of laying period hen-day egg production was slightly but significantly(P<.05) improved by feeding the yeast culture. The average egg weight and daily egg weight(g /day) were also increased by the yeast culture. Feeding the yeast culture did not increase feed intake but feed efficiency was improved significantly (P<.05). No significant difference was detected in egg or eggshell qualities between control and yeast culture-treated groups. Feed intake and egg weight were not affected by the yeast culture feeding under both cold and hot period, but egg production and feed efficiency during hot summer improved significantly by its feeding. This result indicates that the effectiveness of the yeast culture feeding is greater during summer than winter for laying hens.

  • This study is to present a female high school summer blouse with high movement functionality and satisfying appearance, surveyed the students for their understanding of summer blouse. Experimental study's research method was questionnaire survey. By using questionnaires, the satisfaction and comfort of each region of the current worn summer blouse was analyzed. The results of this research are as follows. After surveying 371 high school students in the Daejeon region on the currently worn summer blouse comfort levels, 48.4% showed dissatisfaction about the width of the sleeves and the armpits and over 93% wanted the use of elastic materials as an alternative. After investigating the summer blouses' mending state, 41% of students that mending their clothes chose the alternation of reducing the overall silhouette of the blouse in all areas. This reflects the female high school students' mentality that thin body shape is the ideal.

  • This study was conducted as part of a summer Korean language and culture program at a university in Korea, aimed at examining the changes in intercultural sensitivity among American students who participated in the program, as well as the Korean students who served as their language partners. The research utilized a mixed-method approach combining qualitative and quantitative analysis. To derive research findings, pre- and post-program Intercultural Sensitivity Scale surveys were administered to participating students and semi-structured interview data were collected from a randomly selected group of six students. The research findings indicated that among a total of twenty-seven students including both American and Korean students, significant changes in intercultural sensitivity were observed in the domain of Interaction Engagement. Furthermore, fourteen American students showed significant changes in their Interaction Confidence, while the Korean students who participated as language partners did not exhibit significant changes in the five subdomains of intercultural sensitivity.

  • This study studied the seasons in the novel Snowy Read and the archetypal characteristics in natural phenomena. Summer and winter are the main seasons of Snowy Road. The cycle of the day is the time of dawn and early morning, evening, or night. It is summer now, and memory day is winter. In Snowy Road, 'I' is in sharp conflict with my mom during the summer season. This conflict is resolved and resurfaced with the feeling of 'love' as the story of the day is told in the mother's memory. It was a long time of conflict and trials for winter in the memory of me and my mother. As a result of examining the circular symbols in the Snowy Road, each symbol represents the 'I' and 'the mother's feelings'. 'I' and 'Mom's Emotions' collide, but they confirm each other's sincerity and rebuild their feelings of conflict with 'love'. In Snowy Road, the mother and son's 'love' shows that the mother's son is deeply in love, but the son's mother's love is also very deep.

  • 방울토마토에 적합한 수경재배방식에 관한 연구 결과, 담액수경에서 주경의 기부직경, 엽장, 엽폭, 화방길이 등의 생육이 가장 좋았으며, 암면재배와 NFT는 유사하였다. 개화시기와 과실의 착색일에 대하여는 각 방식마다 차이를 보이지 않았으나, 과실의 수확량은 담액수경에서 많았다. 건물율, 유기산, 경도, 당도 등은 담액수경에서 낮았고, 당산비와 vitamin C는 높아 담액수경에서 품질이 약간 우수한 것으로 나타났다. 따라서, 방울토마토의 여름재배에서는 담액수경방식이 바람직한 것으로 평가되었다.

  • As the population of consumers of outdoor wear expands, there is increasing interest among consumers in trendy lifestyle outdoor. Accordingly, it is essential to develop designs that are drawn from outdoor wear. This can be limited to traditional mountaineering suits, and designs developed from men's outdoor zip-up T-shirts, which are highly utilized in everyday life, are very important. This study developed the design of a summer zip-up T-shirt for men with both functional and aesthetic qualities. Visual images of foreign brands and domestic outdoor-focused T-shirts from the spring/summer seasons of 2013-2019 were collected to analyze the following modeling elements: silhouettes, details, colors, materials, and prints. In addition, the design concept was derived by analyzing presentations from the global outdoor trade Fairs (2013-2019). To develop a sustainable eco-friendly outdoor summer T-shirt for men, the concept was derived according to three categories: eco-friendly, sportism-expressed active elements of sports, and an outro-concept of urban town wear as an outdoor lifestyle. Thus, a total of 12 styles of design were developed. High utilization of the outdoor wear T-shirts (which are also popular as lifestyle wear), is an important aspect of building a segmented lineup of the slow-growing outdoor wear market and supports expansion of the scope of theoretical research on outdoor wear design.

  • 본 연구는 2종류의 하우스, 즉 1-2W 형 하우스와 무기둥하우스에, 시설억제재배, 촉성계배, 반측성재배 그리고 여름재배의 4 재배시기에 8개의 오이 품종을 재식하여, 재배시기에 따른 품종들의 암수꽃의 발생, 개체 당 과실수에 따른 퇴화 과실수, 그리고 수량을 조사 비교하여 각 작형에 알맞은 품종들을 추천하기 위해 수행하였다. 시설억제재배에서는 낙합계나 흑진주계 또는 입추백다다기오이가 생육 및 수량이 양호하였고, 촉성재배에서는 겨우살이청장오이, 입추백다다기오이 그리고 가을낙합오이가 추천된다. 반측성재배에서는 청장계 오이나 낙합계 오이가 비교적 양호한 수량을 보였으며 여름재배에서는 남부청장오이나 가을낙합오이가 양호하였다.

  • 파프리카 정식방법이 생육과 수량에 미치는 영향을 구명하기 위해 늦은 겨울에 파종하여 여름에 수확하는 여름재배와 여름에 파종하여 초겨울부터 수확하는 겨울재배의 두 재배작형을 시험하였다. 대조구는 10cm 암면블록에서 본엽이 8매정도 전개되었을 때 정식하였고, 어린묘 정식은 7cm 블록에서 본엽 2-3매에 정식하였다. 가정식 후 정식 처리는 10cm 암면블록에 이식한 묘를 재배용 배지 위의 받침대 위에 올려 본엽이 8매가 전개되도록 2-3주 동안 육묘한 뒤 정식하였고, 무블록 배지 직접 정식 처리는 본엽 2-3매 묘를 재배용 배지에 구멍을 내고 U자로 구부려 정식하였다. 초장은 대조구와 무블록 배지 직접 정식 처리에서 길었고 가정식 후 정식처리가 짧았다. 잎 크기는 여름과 겨울재배 모두에서 무블록 배지 직접 정식과 어린묘 정식 처리에서 컸고, 가정식 후 정식처리가 작았다. 엽수는 무블록 배지 직접 정식 처리가 많았고, 가정식 후 정식 처리가 적었다. 과실크기는 처리간 차이가 없었지만, 평균 과중은 겨울재배에서는 가정식 후 정식처리가 낮았고, 여름재배에서는 무블록 배지 직접 정식과 가정식 후 정식처리에서 낮았다. 상품과수는 무블록 배지 직접 정식 처리가 가장 많았고 가정식 후 정식처리에서 적었다. 상품률은 겨울재배에서는 차이가 없었지만, 여름재배에서는 무블록 배지 직접 정식 처리에서 가장 높았고, 대조구에서 낮은 경향이었다. 수량은 무블록 배지 직접 정식과 어린묘 정식 처리가 높았고, 가정식 후 정식처리가 낮았다. 이상의 결과로 무블록 배지 직접 처리가 대조구에 비해 초기 활착이 빨라 생육이 왕성하였고, 이로 인해 1그룹 수량에 긍정적으로 작용하였으며 암면 블록을 사용하지 않고 배지에 직접 정식함으로써 암면 블록 비용 절감과 육묘에 드는 노력을 줄일 수 있을 것으로 기대하였다.
