Clark type의 산소전극장치를 이용하여 기 선발된 oxyfluorfen 및 bensulfuron-methyl 에의 내성 및, 감수성 수도품종에 대한 광합성 및 호흡반응차이를 비교한 목적으로 본 시험이 수행되었다. 결과를 요약하면 다음과 같다. Oxyfluorfen 농도증가로 $O_2$ 발생율은 저하하는 반면에 호흡율은 상승하였다. 벼 풍종간에는 $10^{-3}$M에서 감수성이었던 Mushakdanti 의 광합성율이 무처리의 43%까지 떨어졌으나 내성이었던 Aichiasahi 는 56%까지로서 상대적으로 덜 떨어졌으며 호흡에서의 품종차이는 거의 없었다. Bensulfuron-methyl 농도증가에 따라서 $O_2$ 발생율은 저하(감수성인 IR 1846은 광합성에서 무처리의 55%까지, 내성인 Chinsurah Boro II 는 77%까지만 저하) 하였고 호흡율은 상승(품종간에 140~149% 내외의 차이)하는 양상으로서 역시 내성품종이 광합성에서 덜 떨어지는 반면 호흡에선 품종간 차이가 인정되지 않는 경향이있다.

Due to the current seriousness of environmental pollution and the eco-friendly movement of the fashion industry, research on sustainable fashion design is being actively conducted. In this study, consumer perception of upcycling products, are divided into image, function, and meaning; and image is further divided into shape, color, and material. It was redefined as pattern, and image recognition was evaluated among men and women in their 20s and 30s, and men and women in their 40s and 50s used as subjects. First, factors that determine each image were extracted based on qualitative analysis of the precedent cases of upcycling bags, and quantitative analysis of the subjects was induced through a questionnaire. As a result of the analysis of evaluation items related to image association, the average frequency analysis of all subjects for each stimuli and the cognitive variance of the frequency analysis by generation by gender were found to be similar. However, awareness of some stimuli by generation showed a significant difference. Overall, in the three stimuli with high overall preference, common features, such as the basic box-shaped symmetrical structure, the monochromatic color of the Munsell system, solid and practical texture, and appropriate use of patterns were identified. In addition, it was confirmed that there was a difference with factors such as femininity, simplicity, touch, and splendor in the measurement factors. In conclusion, it is considered that the main significance of this study is that it excluded the recognition and meaning of upcycling products and explored the original design and image elements of products. Therefore, it is expected that this study will be used as a basic data for responding to the gender image of each generation as an alternative method of sustainable fashion design, and it will be an opportunity to expand the scope of the study to a detailed study beyond the biased topic.

Whilst there are growing interests in pursuing energy efficiency and zero-energy buildings in built environment, it is widely recognised that Building-Integrated Photovoltaic (BIPV) is one of the most promising and required technologies to achieve these goals in recent years. Although BIPV is a broadly utilized technique in variety of fields in built environments, it is required that generation of BIVP should be analysed and calculated by external specialists. The aim of this research is to focus on developing a new diagram for prediction of the pre-estimation model in early design stage to harness solar radiation data, PV types, slopes, azimuth and so forth. The results of this study show as follows: 1) We analysed 162 districts in a national level and the examined areas were categorised into five zones. The standard deviation of the results was 2.9 per cent; 2) The increased value of solar radiation on a vertical plane in five categorised zones was 42kWh/m3, and the result was similar to the average value of 43.8kWh/m3; and 3) The pre-estimation of diagram was developed based on the categorisation of zones and azimuth as well as the results of the developed diagram showed little difference compared to the previously utilised method. The suggested diagram in this paper will contribute to estimate BIPV without any external contribution to calculate the value. Even though the result of this study shows little difference, it is required to investigate a number of different variables such as BIPV types, modules, slope angle and so forth in order to develop an integrated pre-estimation diagram.

국가적 그리고 사회적 피해 방지 노력에도 불구하고 보이스피싱으로 인한 재산 피해의 규모가 좀처럼 줄지 않고 있는 실정이다. 이는 최근의 보이스피싱이 세련된 말투와 전문용어를 사용함으로써 범죄자를 인지하기 어렵게 만들기 때문이다. 더 나아가 개인정보 취득과 실제 관광서등에서 근무하는 종사자들이 실제 현장에서 사용하는 전문용어를 구사하여 젊은 층을 집중적으로 속이고 있는 실정이다. 이는 결과적으로 노년층보다 판단력이 있는 20~30대의 젊은 층의 피해가 급증하고 있는 상황과 직결된다. 이를 위해 본 논문에서는 실제 보이스피싱에 사용된 보이스피싱의 음원과 보이스 피싱 범죄자와 동년배의 일반 젊은 층을 대상으로 같은 문장을 읽고 이에 대한 음성을 비교. 분석을 행하였다. 실험은 2011년 이후 최근까지 보이스 피싱을 행한 범죄자 목소리의 음성적 특징이 무엇인가를 음성의 음높이와 그 대역폭, 음성에 실리는 에너지 및 발화속도, 음색 등을 기반으로 수행하였다. 실험 결과 음성에 실리는 에너지와 발화속도에 있어 의미 있는 차이가 있음을 규명해 낼 수 있었다.

Solar hot water system produces hot water using solar energy. If it is not used effectively, overheating occurs during the summer. Therefore, a lot of research is being done to solve this. This study develops thermoelectric power module applicable to solar hot water system. A thermoelectric material can directly convert thermal energy into electrical energy without additional power generation devices. If there is a temperature difference between high and low temperature, it generate power by Seebeck effect. The thermoelectric module generates electricity using temperature differences through the heat exchange of hot and cold water. The water used for cooling is heated and stored as hot water as it passes through the module. It can prevent overheating of Solar hot water system while producing power. The thermoelectric module consists of one absorption and two radiation part. There path is designed in the form of a water jacket. As a result, a temperature of the absorption part was $134.2^{\circ}C$ and the radiation part was $48.6^{\circ}C$. The temperature difference between the absorption and radiation was $85.6^{\circ}C$. Also, The Thermoelectric module produced about 122 W of irradiation at $708W/m^2$. At this time, power generation efficiency was 2.62% and hot water conversion efficiency was 62.46%.
