  • 본 논문에서는 지중전력설비의 안전한 운용을 위하여 무선네트워크기술을 적용한 감시시스템을 개발하기 위하여 WiMAX 기술을 적용하기로 하였다. 지중전력설비는 환경친화적 도시설비의 추구로 전체 전력설비중에서 비중이 꾸준히 늘어나는 추세이다. 노후화되어가는 전력설비는 사고의 위험성이 증대되고 있다. 하지만 노후화된 전력설비를 교체하는 비용은 천문학적이므로, 교체보다는 안전하게 유지보수하는 방법이 훨씬 경제적일 것이다. 지중전력설비는 지상설비만큼이나 광범위한 거리에 걸쳐서 시설되어 있다. 그러므로 노후한 설비를 유지보수하기 위하여 유선네트워크를 사용하는 방법보다는 경제적으로 무선네트워크를 사용하는 방법이 유리하다. 무선네트워크 기술은 종류에 따라서 여러가지 장단점을 가지고 있으며, 지중설비 감시에 최적인 기술을 채택하는 것이 중요하다. WiMAX 기술를 적용하여 지중전력설비 감시에 사용하여 기존에 설치한 유선네트워크에 영향을 주지않으면서, 신규로 추가되는 센서네트워크 시스템을 쉽게 통합 관리할 수 있는 시스템을 설계하기로 한다.

  • 해외 글로벌 쇼핑 사이트들을 통한 직접 구매를 일컫는 해외직구 금액이 2013년 5881억원 발생하며, 대한민국 전체 경제의 0.2%를 차지하게 되었다. 구입지역도 미국 뿐만 아니라 중국, 독일로 점차 확대되고 있다. 해외직구의 시장은 향후에도 지속적으로 증가 될 것으로 예측되는데, 이처럼 해외직구가 발전하게 된 성장 배경에는 내수시장보다 저렴한 가격, 해외 온라인 쇼핑 사이트들의 진화, 전문 배송업체의 등장, 커뮤니티 정보 공유 활성화 등으로 인하여 해외직구에 대한 폭발적인 반응으로 연결된 것으로 보인다. 하지만 최근에 정치권의 움직임은 해외직구를 규제하여 통제하려는 움직임이 크다. 제 물품을 확인하지 않고 목록 신고만으로 수입통관이 허용되어 허위 신고 가능성이 높아졌다는 것과 이에 따른 관세 탈루 및 마약을 비롯한 수입금지 물품의 국내 반입 위험성 또한 증가한다고 정부는 말하고 있다. 이것은 매우 잘못된 해석으로 판단된다. 소비자들의 소득 발생으로 인한 소비 할 수 있는 절대치는 감소하고 있는데도 불구하고, 국내 대기업들의 상품 판매 하락이 합리적인 가격으로 판매하고 있는 해외 사이트들로 피해자가 된듯한 표현을 하여, 해외 제품을 구매하려는 소비자를 규제한다는 것은 어불성설에 해당된다. 소비자들은 항상 합리적인 선택을 추구하려고 하기 때문에 여러 가지 요소들을 고려한다. 이러한 소비자들의 심리를 파악하여 국내 소비자들이 불만을 가지고 있는 내수시장의 가격 부분에 대한 심리적 회유책을 적용하여 가격 경쟁력에 대한 인식을 새롭게 고려 할 수 있도록 하는 개선안을 제시해 본다.

  • 홍수 시의 산지하천 만곡부는 2차류 발생과 편수위 상승에 따른 하상세굴 및 홍수범람 위험이 크다. 만곡부 외측에 주로 설치되어 있는 콘크리트 옹벽호안은 표면이 매끄러워 홍수피해를 가중 시킨다. 이러한 피해를 저감시키기 위해 콘크리트 옹벽에 돌출줄눈을 설치하여 유속조감 및 설치효과를 분석한 바 있다. 본 연구에서는 기존에 제안된 직사각형 단면의 돌출줄눈보다 내구성을 추구한 사다리꼴 단면의 돌출줄눈을 제시하여 수리모형 실험을 수행하였다. 수리모형 실험은 개수로 직선수로에서 수로경사 0.0035 조건에서 수로 출구 게이트를 조절하면서 이루어졌다. 모형 돌출줄눈의 조도높이는 3cm로 하였으며, 사다리꼴 밑각은 $45^{\circ}$로 완만한 경우이다. 설치간격은 무차원 돌출줄눈 간격을 기준으로 ?형 조도인 6으로 하였다. 돌출줄눈의 설치 유무에 따라 유량에 따른 수위를 측정하고 유속을 산정하여, 마찰저항의 변화를 파악하였다. 공급유량에 따른 Froude 수는 0.168~0.359 범위였으며, 유량이 증가에 따라 Manning의 조도계수는 감소하였다. Froude 수가 0.25보다 큰 경우 돌출줄눈설치의 조도계수가 미설치보다 큰 것으로 파악되었다. 그러나 사다리꼴 돌출줄눈의 흐름저항효과는 직사각형 돌출줄눈에 비해 상대적으로 작았다. 수로 횡단면의 수위분포에 따르면, 돌출줄눈 설치 측벽 주변에서 흐름저항에 따른 유속감소와 수위상승 효과가 나타나는 것으로 파악되었다. 이번 사다리꼴 돌출줄눈은 흐름저항 효과가 크지 않았기 때문에 사다리꼴 밑각을 조정하여 새로운 단면에 대한 추가적인 실험이 필요할 것으로 보인다.

  • 우리 헌법은 인간의 존엄과 가치 그리고 행복을 추구할 권리를 보장하고 있으며, 편의증진법과 교통약자법을 통해 장애인등이 교통수단, 여객시설 및 도로 등을 비장애인들과 차별 없이 이용하여 이동하고, 도로와 대중교통수단, 공공 건축물과 주거 등 생활 필수시설에 자유롭게 접근하기 위한 접근권을 보장하고 있다. 우리나라는 이동권의 보장을 편의시설 제도라는 독자적인 체계를 통해 이루어지고 있으며, 이를 실질적으로 보장하기 위하여 장애물 없는 환경 인증 제도(BF 인증제도)를 도입하였다. 시행 15년을 맞은 BF 인증제도는 양적으로는 많은 발전을 가져왔지만, 질적으로 특정 건축물 등 일부에 대한 인증 편중 현상이 있으며 안전취약계층에 대한 재해 안전확보에 대한 고려가 포함되지 않아 부진정한 이동성과 접근성의 보장이라는 한계를 가지고 있다. 이동권 보장이 얼마나 잘 이루어지느냐는 그 나라의 사회 안전망이 얼마나 잘 갖추어져 있는지 판단하는 척도라 할 것이며, 따라서 이러한 이동권 보장은 위험상태에서의 안전한 피난을 함축하고 있으며 중첩적으로 국가의 기본권 보호 의무의 이행과 관련된다. 이에 따라 이동권과 접근권의 증진을 위한 BF 인증 규정을 안전 규범으로 보완하여 장애인과 비장애인이 사회의 일원으로서 평등한 인격적 주체로 공동체에 기여하는 안전한 사회적 환경의 조성이 긴절히 요청된다고 할 수 있다.

  • After the 2020 Corona 19 pandemic, consumers' online consumption is increasing rapidly, and non-store online retail channels are showing high growth. In particular, social media is gaining its status as a social media market where direct transactions take place in the means of promoting companies' brands and products. In this study, changes in consumer behavior after the Corona 19 pandemic are different in choosing online shopping media such as existing online shopping malls and SNS markets that can be classified into open social media and closed social media when purchasing agri-food online. We tried to find out what type of product is preferred in the selection of agri-food products. For this study, demographic characteristics of consumers, perceived risk of consumers, and dietary lifestyle were set as independent variables to investigate the effect on online shopping media type and product selection. The summary of the empirical analysis results is as follows. When consumers purchase agri-food online, there are significant differences in demographic characteristics, consumer perception risks, and detailed factors of dietary lifestyle in selecting shopping channels such as online shopping malls, open social media, and closed social media. Appeared to be. The consumers who choose the open SNS market are higher in men than in women, with lower household income, and higher in consumers seeking health and taste. Consumers who choose the closed SNS market were analyzed as consumers who live in rural areas and have a high degree of risk perception for delivery. Consumers who choose existing online shopping malls have high educational background, high personal income, and high consumers seeking taste and economy. Through this study, we tried to provide practical assistance by providing a basis for judgment to farmers who have difficulty in selecting an online shopping medium suitable for their product characteristics. As a shopping channel for agri-food, social media is not a simple promotional channel, but a direct transaction. It can be differentiated from existing studies in that it is approached as a market that arises.

A Study on the Consumers' Inherent Characteristics Influencing on the Relationship Building Intention with the Salesperson: Relational Benefits as Mediating Variables (영업사원과의 관계구축 의도에 영향을 미치는 소비자의 내재적 특성에 관한 연구: 관계적 혜택을 매개변수로)

  • As the competition intensifies and the market matures, marketers are more and more concerned with the relationship marketing. Many of the previous researches have pointed out that not all of the consumers are relationship-oriented. But none of the previous research has systematically investigated this issue. This research investigated the relationship among the three concepts: consumers' intrinsic characteristics, perceived importance of relational benefits, and relationship building intention with the salesperson. In this research the perceived importance of relational benefits is treated as mediating variable in the relationship between consumers' intrinsic characteristics and relationship building intention with the salesperson. The conceptual model in this study can be depicted as follows. From the consumers' perspective relational benefits can be defined as "the additional benefits consumers can receive in addition to core services through the long-term relationship with the service provider." And in this study two kinds of relational benefits are adopted by reviewing the previous research: confidence benefits and social benefits. Relational benefit received from the salesperson is very important to predict consumers' relationship building intention with the salesperson. The more relational benefits consumer wants from the salesperson, the more relationship building intention he/she has. From this point two hypotheses are derived as follows. Hypothesis 1: As the perceived importance of confidence benefit from the salesperson increases, the relationship building intention with the salesperson increases. Hypothesis 2: As the perceived importance of social benefit from the salesperson increases, the relationship building intention with the salesperson increases. In this study four individual characteristics(risk taking tendency, variety-seeking tendency, product knowledge, trust orientation) are hypothesized to influence the perceived importance of confidence benefits from the salesperson. And three individual characteristics(interpersonal orientation, price consciousness, trust orientation) are hypothesized to influence the perceived importance of social benefits from the salesperson. These 7 hypotheses are as follows. Hypothesis 3: As the risk taking tendency increases, the perceived importance of confidence benefits from the salesperson decreases. Hypothesis 4: As the variety-seeking tendency increases, the perceived importance of confidence benefits from the salesperson decreases. Hypothesis 5: As the product knowledge increases, the perceived importance of confidence benefits from the salesperson decreases. Hypothesis 6: As the trust orientation increases, the perceived importance of confidence benefits from the salesperson increases. Hypothesis 7: As the interpersonal orientation increases, the perceived importance of social benefits from the salesperson increases. Hypothesis 8: As the price consciousness increases, the perceived importance of social benefits from the salesperson decreases. Hypothesis 9: As the trust orientation increases, the perceived importance of social benefits from the salesperson increases. The whole model in this study can be depicted as follows: Data were collected from the 396 consumers who actually trade stocks through the salesperson and were analyzed using structural equation model. The analysis results show that consumers' perceived importance of relational benefits(confidence benefit and social benefit) play the roles of mediating variables in the causal relationship between consumers' inherent characteristics and their relationship building intention with the salesperson. As for the individual characteristics, the influences of variety-seeking tendency, trust orientation, and price consciousness are statistically significant. It was found that variety-seeking tendency has a significant negative effect on the perceived importance of confidence benefit, and that trust orientation has a significant positive effect on the perceived importance of both of confidence and social benefit. Finally it was also found that, on the contrary to the influence direction suggested in the hypothesis, price consciousness has a significant positive effect on the perceived importance of social benefit.

  • In recent years, as interest in youth startup has increased, the Korean government has established various policies to support young entrepreneurs and actively implements such policies. Especially, as a way to promote youth startup, the development of startup clubs in universities is being suggested, and the importance of startup clubs is growing day by day. As reflected in these points, the Korean government is increasing its budget every year to support the startup clubs of universities, and actively supports the funds and space required for the startup clubs of universities. Unfortunately, however, despite the growing importance of startup clubs and the active support of the government for the startup clubs, academic attempts to see how effectively the startup clubs are operating are not enough. For this reason, this study analyzes the effect of entrepreneurship of university start-up club members on the effectiveness of start-up club. More specifically, in this study, entrepreneurship of club members is classified as risk-taking propensity, proactiveness, and innovativeness, as emphasized in previous researches. We empirically analyzed the effects of these independent variables on the effectiveness of the start-up clubs, focusing on the moderating effect of club members' diversity. We conducted empirical analyses on 1112 start-up club members from 12 universities located in Jeollanam-do and Jeollabuk-do, and the analysis results are as follows. First, the entrepreneurship of the start-up club members, namely risk taking propensity, proactiveness and innovativeness, all have a positive effect on the effectiveness of the start-up club. These results are consistent with the emphasis of many previous studies. The higher the tendency to take risks, the more inclined to move forward through difficulties, and the higher the tendency to break out of the existing framework and pursue new things, suggesting that the effectiveness of the club is enhanced. Second, as a result of verifying the moderating effect of the club members' diversity, it was found that club members' diversity moderates the relationship between the proactiveness of club members and club effectiveness in the negative (-) direction. In other words, the positive effect of the entrepreneurship of club members on the effectiveness of the start-up club means that the proactiveness is weakened in the case of a club having members from different major backgrounds. The results of this study are expected to provide meaningful theoretical and practical implications by identifying the influencing factors of the start-up club's effectiveness, which has not received much attention so far.

  • Background : Primary multidrug-resistant tuberculosis is defined as Mycobacterium tuberculosis isolates that are resistant to at least isoniazid and rifampin in never-been-treated tuberculosis patients, and this malady is caused by the transmission of a resistant strain from one patient, who is infected with a resistant Mycobacterium tuberculosis strain, to another patient. The prevalence of primary multidrug-resistant tuberculosis could be a good indicator of the performance of tuberculosis control programs in recent years. We conducted a case-control study to identify the risk factors for primary multidrug-resistant tuberculosis. Methods : From January 1, 2001 to, June 30, 2003, by conducting prospective laboratory-based surveillance, we identified 29 hospitalized patients with P-MDRTB and these patients constituted a case group in this study. The controls were represented by all the patients with culture-confirmed drug susceptible tuberculosis who were admitted to National Masan Hospital during the same study period. The odds ratios for the patients with primary multidrug-resistant tuberculosis, as compared with those of the patients with drug susceptible tuberculosis, were calculated for each categorical variable with 95% confidence intervals. Results : Multivariate logistic regression showed that the presence of diabetes mellitus (odds ratio 2.68; 95% confidence interval, 1.05-6.86) was independently associated with having primary multidrug-resistant tuberculosis. Conclusion : This study has shown that diabetes mellitus might be one of the risk factors for primary multidrug-resistant tuberculosis.

  • This study examined whether any differences can be found in desirable character traits and creative personality characteristics depending on the appearance management behaviors of male and female adolescents in Gwangju, South Korea. It was conducted by administering a self-report survey to 544 male and female middle school students. The collected survey data were analyzed by Means, Cronbach's ${\alpha}$, Factor analysis, One-way ANOVA, and Duncan-test using the SPSS/PC WIN 19.0 statistical program. The results were as follows: According to the results of the survey, total coordination seeking in appearance management behavior is very important to teens and is deeply related to desirable character traits and creative personality characteristics. Desirable character traits show positive results for basic living habits, filial piety, respect and affection. Creative personality characteristics show positive results for curiosity, open thinking, risk taking, assignment completion and esthetic appreciation. Considering these findings, there is a need for supplementary content on total coordination seeking behavior in home economics courses. Positive effects in terms of desirable character traits and creative personality characteristics can be expected through after class activities involving clothing habits or searching for a path in life and given the depth of education related to total coordination through a free semester system.

  • Confucianism and Buddhism were compatible in the period of Goryeo Dynasty. And then, the rulers worshiped Confucianism and repressed the religious activity of the Buddhist monk in the early years of the Joseon Dynasty. But King Sejong planed to bring reconciliation between Confucianism and Buddhism. Especially on the ceremonies of mourning and sacrificial rituals, he always performed the two religious style. The reason of sticking to his amicable consciousness is as follows. Firstly, he thinks that both the theory of Confucianism and the religious spirit of Buddhism are very important for the building up the foundation of his Dynasty. Secondly, his mind has been of a same faith cure on the incurable disease. Therefor, when the Royal family is taken ill he must pray to Buddha for recovery from the first stage. Thirdly, he regards social conditions to be the most important and respect for man's life and dignity for the purpose of beneficent administration. But Joseon's government line was the anti-Buddhist policy. So, the policy came in the wake of a debate among King Sejong and Confucian government officials. However his harmonious mind was unchanged between Confucianism and Buddhism. After all, in the last phase of his life he was deeply religious on Buddhism. I think that King Sejong's amicable consciousness could make a contribution to overcome religious conflicts and to create a new political cultural form in the modern society
