The purpose of this study was to investigate the effects of emotional-utilitarian motivation on coffee shop selection attribution. Based on a total of 276 samples obtained from empirical research, the results of the survey were analyzed by using SPSS 22.0. The results of this study were as follows. Firstly, the results of exploratory factor analysis of coffee shop selection attribution emphasized service, coffee quality, diversity of menu, atmosphere, convenience, and price. Secondly, the customers showed higher emotional motivation than utilitarian motivation. Thirdly, emotional motivation had a significant effect on perception of ‘service’, ‘coffee quality’, and ‘atmosphere’. On the other hand, utilitarian motivation had a significant effect on ‘service’, ‘diversity of menu’, ‘convenience’, and ‘price’.

In many insects, female receives a large amount of sperm and ejaculates upon copulation, and keeps them in her uterus for some time, during which she stores sperm. After varying delays, the female removes unused sperm and ejaculates through sperm ejection behavior, which is known as a major mechanism for the post-copulatory sexual selection. In the fruitfly Drosophila melanogaster, timing of sperm ejection behavior is controlled by the diuretic hormone 44 (Dh44) pathway. To identify pathways that regulate Dh44 activities and sperm ejection, here we examine effects of olfactory cues. We will present our recent results suggesting that male odors can be one of upstream signaling pathway that modulates a brain neuropeptide pathway.

The background of this study is to establish a systematic development process for SSD(Solid State Drive) which is being watched as the next generation auxiliary memory device and to make stable production. In order to do so, we select the two products that have been developed and classify and analyze all defects generated in each product by type and process of defects. The root cause of the fault and its background were reflected in the contradiction matrix of TRIZ's technical contradiction, and the improvements suggested in the 40 inventive principles were reflected in the test case design methodology of each process. Finally, this study suggests a process optimization method for systematic development.

Probiotic functional foods are known to have various functional effects such as intestinal regulation, modulation of immune system, reduction of allergies, and lowering of cholesterol. The purpose of this study was to select probiotic strain that is most suitable for freeze-dried coffee for the development of functional coffee products. The survival rate of probiotics, at drinking condition of coffee, at acid, at bile and after freeze-dried in coffee were measured on 1 strain isolated from commercial freeze-dried coffee, 8 strains used as fermented milk starter, 1 Bifidobacterium and 1 Bacillus coagulans. Bacillus coagulans showed the highest survival rate from 2.4×107 cfu/g to 2.0×107 cfu/g especially after freeze-drying. The results at drinking condition of coffee, at acid tolerance, at bile tolerance and at storage test showed significantly better survival rate of Bacillus coagulans than that of control (Lactobacillus casei). Especially, Bacillus coagulans showed 3.8-fold higher survival rate at acid tolerance (pH 1, 120 minutes) than control. Thus, the lactic acid-producing Bacillus coagulans is characterized as a probiotic strain suitable for functional coffee formulation and commercialization.

Stable Isotope Analysis (SIA) of carbon and nitrogen is useful tool for the understanding functional roles of target organisms in biological interactions in the food web. Recently, mixing model based on SIA is frequently used to determine which of the potential food sources predominantly assimilated by consumers, however, application of model is often limited and difficult for non-expert users of software. In the present study, we suggest easy manual of R software and package SIAR with example data regarding selective feeding of crustaceans dominated freshwater zooplankton community. We collected SIA data from the experimental mesocosms set up at the littoral area of eutrophic Chodae Reservoir, and analyzed the dominant crustacean species main food sources among small sized particulate organic matters (POM, <50 μm), large sized POM (>50 μm), and attached POM using mixing model. From the results obtained by SIAR model, Daphnia galeata and Ostracoda mainly consumed small sized POM while Simocephalus vetulus consumed both small and large sized POM simultaneously. Copepods collected from the reservoir showed no preferences on various food items, but in the mesocosm tanks, main food sources for the copepods was attached POM rather than planktonic preys including rotifers. The results have suggested that their roles as grazers in food web of eutrophicated reservoirs are different, and S. vetulus is more efficient grazer on wide range of food items such as large colony of phytoplankton and cyanobacteria during water bloom period.

본고는 초등학교 한자교육의 중심을 어휘 교육으로 파악하고 초등학교 어휘 교육 과정에 필요한 字數와 字種을 제안하는 것을 중심 목표로 삼는다. 먼저 선행 연구의 방법･의의 및 한계를 종합하고 이 바탕 위에 김한샘(2009)과 ㈜낱말 어휘 정보 처리 연구소의 데이터 등을 추가적으로 활용하여 ‘초등학교용 교육용 한자’의 선정안을 제시하였다. 구체 논의 과정에서는 초등학교 교과서라는 말뭉치, 등급별 어휘라는 어휘 평정, 조어력, 전문가의 판단 등을 고려해 초등학교 한자교육에 필요한 적정 한자 수 및 한자 선정에 대한 논의를 펼쳤다. 이 중 ‘초등학교 교과서’라는 말뭉치는 그동안 단순 빈도의 측면에서만 이용되었던 것이고, 등급별 어휘와 조어력은 초등학교 교육용 적정 한자 수 선정 시 학계에 처음으로 고려된 것이다. 본고의 논의가 초등학교 교육 현장에서 신뢰하고 활용할 수 있는 ‘초등학교용 교육용 한자’의 선 정에 일정한 보탬이 되기를 바란다.

본 연구는 2008년부터 2012년까지 오목눈이의 번식기에(2월에서 6월) 공주대학교 교내 및 인근지역과 계룡산국립공 원 그리고 월악산국립공원에서 수행하였다. 총 98개의 오목눈이 둥지를 조사결과 15종의 수목에 둥지를 만들었으며, 특별히 선호하는 나무의 수종은 없는 것으로 나타났다. 그러나 나무의 수종을 생활형으로 구분하여 분석한 결과, 상록침 엽교목과 낙엽활엽교목 그리고 낙엽활엽관목으로 나타났으며 그중 상록침엽교목을 선호하는 것으로 나타났다. 식생에 의해 오목눈이의 둥지가 가려진 정도인 은폐도는 공주대학교 교내 및 인근지역이 11.61±4.79%(n=29)로 나타났으며, 계룡산국립공원은 6.06±2.31%(n=43), 월악산국립공원은 4.38±2.19%(n=26)로 나타났다. 지역별로 이웃한 오목눈이 둥지의 은폐도는 서로 비슷한 정도로 가려져 있었으나, 지역 간의 은폐도는 상관관계가 없는 것으로 나타났다. 또한 오목눈이 둥지의 보호색 정도를 살펴본 결과, 오목눈이 둥지주변 환경의 색 코드 값에서 오목눈이 둥지의 색 코드 값을 뺀 평균은 26.52±16.14(n=32)로 나타났으며, 오목눈이의 둥지는 주변 환경에 따라서 보호색을 띠고 있는 것으로 나타났다. 오목눈이 둥지의 영소목이 상록침엽교목이면 녹색의 이끼를 많이 물어와 둥지를 만드는 반면 관목이나 영소목이 균류 등에 의하여 노란색을 띠게 되면 마른이끼를 둥지 재료로 사용하여 전체적으로 노란색을 띠는 경향이 있었다.

본 연구는 9종의 국화과 식물을 대상으로, 생리적 특성 및 생화학적 물질을 관찰함으로써 내건성식물 을 선발하였다. 크기와 생장이 균일한 식물체를 선발한 후, 단수처리를 통하여 건조 스트레스를 유발하 였다. 내건성식물 선발을 위해 엽록소함량, 엽록소함량, 상대수분함수량, 상대수분손실량, 프롤린, 환원 당을 단수일로부터 30일동안 관찰하였다. 식물 생존율은 단풍취, 벌개미취, 참취, 좁은잎구절초 순으로 높게 나타났고, 나머지 5종은 고사하였다. 내건성식물 선발을 위한 나머지 요인들은 높은 생존율을 얻 은 식물종을 기준으로 판단되었다. 그러나 엽록소함량은 단풍취, 단양쑥부쟁이, 벌개미취 순으로 높은 값을 보여, 단풍취와 벌개미취를 제외하고는 생존율과 연관성을 갖지 않는다고 판단되었다. 반면에 상 대수분함수량, 상대수분손실량, 프롤린, 환원당에서는 참취, 단풍취, 벌개미취 3종이 상대적으로 높은 내건성식물로 판단되었고, 생존율과도 비슷한 연관성을 나타내었다. 결론적으로 국화과 식물 9종 중 참 취, 단풍취, 벌개미취 3종이 상대적으로 내건성이 높다고 판단되었다.

The purpose of this study was to investigate the purchasing behavior and selection attributes for Home Meal Replacement (HMR) and to identify the selection attributes affecting purchasing frequency and purchasing costs of married women living in a city. Among 837 questionnaires distributed to HMR married women consumers, 752 complete questionnaires (89.8%) were analyzed. The younger married women group showed higher frequency of purchasing HMR than the older age group. The 20s and 30s age groups showed higher purchasing costs for HMR than the 40s and older age groups. A higher proportion of employed married women purchased HMR three or more times per week and spent an average of more than 20,000 won per purchase in comparison with unemployed married women. HMR selection attributes were classified into five factors: ‘taste and sanitation’, ‘economic efficiency’, ‘health and nutrition’, ‘convenience’, and ‘reliability and awareness’; mean scores of these factors’ importance levels were 4.28, 3.93, 3.59, 3.54, and 3.50 out of 5 points, respectively. The importance level of ‘taste and sanitation’ factor was significantly greater as married women’s age decreased. However, the importance level of ‘health and nutrition’ factor was significantly greater as married women’s age increased. The results of the logistic regression analyses indicate that the ‘taste and sanitation’ and ‘health and nutrition’ factors affected frequency of purchasing HMR. The ‘reliability and awareness’ factor had the most significant impact on cost per purchasing HMR. Therefore, a product differentiation strategy according to married women’s age and employment status should be applied. Product qualities and brand value should be improved to enhance competition in the HMR market.

Pine wilt disease (PWD) is one of the most important forest tree diseases, especially in the East Asian countries of Japan, China, and Korea. The Japanese pine sawyer, Monochamus alternatus Hope, is the PWN vector for Japanese red pine and Japanese black pine while Monochamus saltuarius Gebler is the vector for Korean white pine. Various control methods, such as aerial pesticide applications, biological control using parasitoids and fumigant such as methyl bromide are used. But the PWD still has spread. Therefore, we were selected effective aerial insecticides. Susceptibility of M. saltuarius and M. alternatus adults were investigated using 9 insecticides which are available in the market in Korea. And then, we tested them to the Apis mellifera to vertify the environmental impact.

무가온 시설토마토 재배지내에서 토마토녹응애 발생양상은 4월 중하순경 최초로 발생하기 시작하여 6월 중하순경 최대 발생을 나타냈다. 하지만 야간기온이 낮을 경우 번식력이 증가하게 되고 주간기온이 높을 경우에는 분산이 활발해져 고온기인 7월에도 지속적으로 증가하는 것으 로 조사되었다. 유기농업자재 11종에 대한 토마토녹응애의 살충독성 실내검정 결과, EOIMa (Matrin 0.6%), EOICo (Clove oil 10%)가 500 배에서 각각 92.1%와 95.1%로 90% 이상의 살충효과를 보였다. 특히 EOIMa 1,000배에서는 90.4%로 90%, EOIMa 2,000배에서는 88.2%의 높은 살충효과를 보였다. 포장검정에서도 EOIMa 1,000배와 EOICo 500배는 각각 91.5%와 93.9%의 살충효과를 보여 두 약제 모두 농약을 대 체하기에 충분하였고 EOIMa의 경우 2,000배에서도 살충효과가 90%에 가까웠기 때문에 예방적 활용도 가능할 것으로 판단되었다.

노후 원전 해체의 경우 부지 특성 및 최종 상태 조사 보고서에 해당 부지내 잔존가능성이 있는 방사성 핵종 정보에 대한 내용 을 포함하여야 한다. 미국 NRC의 경우 이에 해당하는 해체기술관련문서(DTBD)를 부지 특성 조사시에 부지이력조사(HSA) 와 같이 사업자 측이 제출하도록 규제하고 있다. 또한 해체기술관련문서는 방사선학적 부지 조사와 해체완료계획서에 포함 되어야 하는 내용으로써 부지 규제 해제와 재이용에 관해서 중요한 자료를 제공한다. 이 논문은 부지 별 잠재적 핵종에 대해 미국 원전의 해체 사례중 부지 특성 및 최종 상태조사 과정에서 결정하는 방법론을 분석하고 2017년 고리 1호기의 영구 운 전정지 후 이루어질 해체 과정에 필수적인 규제 지침과 기술적 근거 수립에 도움이 되고자 한다.

Various kinds of processes are used in the Public Sewage Treatment Works(PSTWs) in order to achieve water quality criteria and TMDL in the watershed. The performance of the existing processes at PSTWs depends on influent characteristics, effluent quality target, amount of sludge production, power cost and other factors. In present, the Selection Guideline for the Available Treatment Process of PSTWs is used for a process decision in the country. But there are some problems regarding redundancy of assessment factors and complexity of assessment procedure in the guideline. In this study, we did a test application of AHP for process selection of PSTWs, which propose is to simplify assessment factors such as pollutant removal amount, sludge generation, electricity consumption, stability of operation, convenience of maintenance, easiness of existing process application, installation cost, and operating cost concerning of environmental factors, technical factors and economical factors. According to the study, the PSTWs selection procedure guideline can be improved using application of AHP method.
