최근 FTA 체결은 국내의 농식품 소비자들을 값싼 외국산 농식품으로 소비 패턴을 변화시킬 수 있다. 또한 유통시장의 변화 즉, 소비자-생산자 간의 직거래 형태는 개인이 프로슈머로서 농식품 관련 컨텐츠의 제작과 생산이 더욱 활발해지도록 하며 소비자들이 구매의사 결정에 중요하게 작용하고 있다. 따라서 농식품의 효과적인 마케팅 전략읠 수립 및 실행을 위하여 소비자가 무엇을 원하고 인식하지 못한 욕구가 있는지 소비자 유형을 분석 할 필요가 있다. 본 논문에서는 농식품 소비자 구매의도를 통한 제품이나 서비스의 이용의도로서 종속변수로 설정하여 구매의도에 영향을 미치는 요인을 분석하였다. 또한 연구 모형을 위해 교류빈도, 친밀감, 호혜성, 감정의 강도라는 SNS 특성을 도출하여 분석하였다.

Recently, the health-pleasure trend, which means enjoying health care through exercise or diet and certifying it on SNS is spreading to the MZ generation. This study examined the effect of personality traits on SNS upload behavior and subjective well-being related to health care. As a result, 1) parallel comparison and narcissism had a positive effect on the SNS upload attitude and intention, and the downward comparison had a negative effect on both SNS upload variable. Self-esteem had a positive effect only on the attitude of uploading SNS. Next, 2) self-esteem had a positive effect on both subjective well-being, while narcissism had a negative effect on stress, and parallel comparisons had a positive effect on life satisfaction. In other words, it was confirmed that comparisons with similar people had a positive effect on SNS upload behavior and their subjective well-being, while health care for self-show or recognition of others had a negative effect on their subjective well-being. The results of this study should be actively reflected not only for the marketing market but also for a media and cultural environment in which the MZ generation can lead a healthy life.

The purpose of this study was to investigate the structural relationship between advertising attributes, advertising attitude, brand image, and purchase intention of sports brand on SNS. For this purpose, 250 valid samples from the convenience sampling method were used as the final analysis data. Entertainment, information, and credibility among ad attributes had a positive effect on SNS users' advertisement attitude toward sport brands, and irritation has a negative effect on ad attitude. The ad attitude formed by the advertising attributes positively affected the image of the sports brand and the purchase intention. Brand image had a positive effect on purchase intention. The results of this study may be helpful to maximize SNS advertising effect of sports brands and to identify some important factors that can affect direct purchasing behavior of sports majors, one of the target groups of companies promoting sports brands using SNS.

For tourism, Information Technology (IT) is the one of the most important factors, therefore, tourism has been open to IT. Through internet, the sources of information became extensive. Smartphone and Social Network Service (SNS) make huge changes in tourism. In line with this, Korea Tourism Organization (KTO) is developing the smart tourism system, composed of internet, smartphone, SNS, as representative of Korea tourism. In this research, KTO's main channels, internet, smartphone, SNS, of smart tourism system will be analyzed as well as the connectivity between the channels.

Internet Explorer is the popular internet browser the most in domestic. In some version of Internet Explorer, user information could be leaked cause CORS(Cross-Origin Resource Sharing) Internet Explorer support. Different before, without setup a malicious program, attacker can get the user information even account information, credit card usage list and user information with SNS or internet portal site logged in regardless of secure program. Not only Internet Explorer but also mobile browser, it could be. In this paper, we make study of the potential disclosure of user information by attack using CORS, second attack and the way to improvement of vulnerability of CORS.

Social Network Services (SNS) have become a vital means of shopping, significantly influencing consumers' purchases of fashion products. The aim of this study was to identify bandwagon consumption among fashion consumers and to analyze the effects of bandwagon consumption on negative emotions, purchase discontinuation, and switching intention. A survey questionnaire was developed, and data were obtained from 285 female consumers in Korea aged in their 20s and 30s who had experienced guilt, regret, or disappointment after purchasing fashion products using SNS during the previous six months. The survey results indicated four different types of band- wagon consumption: intentional, impulsive, unintentional, and planned. The presence of negative emotions such as guilt, disappointment, and regret were affected by different types of bandwagon consumption. Intentional bandwagon consumption only affected guilt, while unintentional bandwagon consumption affected both guilt and disappointment. Impulsive bandwagon consumption affected guilt and regret; however, planned bandwagon consumption only affected regret. Furthermore, negative emotions affected purchase discontinuation and switching intention. Planned bandwagon con- sumption had an effect on both purchase discontinuation and switching intention, while both impulsive and unintentional bandwagon consumption influenced switching intention only. Intentional bandwagon consumption had no effect on either purchase discontinuation or switching intention. The results of this study indicate that SNS consumers' bandwagon consumption causes different negative emotions, purchase discontinuation, and switching intention.

A pot experiment was carried out to examined the effect of electrolyzed micronutrients (Fe, Mn, Zn, Sr, Se, Sn, Co, Ti, and V) solution treatments with nutrient solution and SCB slurry on the mineral content and growth of tomato in cherry tomato (Lycopersicon esculentum). The treatment of nutrient solution (NS)+micronutrients solution (MS) significantly increased the concentrations of Li, Zn, Sr, Se, Ti as compared with that of NS alone in the cherry tomato fruits, and SCB+MS solution treatment significantly increased Li, Zn, Se, Co, Sr, and Ti contents as compared with SCB treatment. The micronutrient contents of MN+SCB+MS treatment were significantly higher in Li, Zn, Se, Co and in Ti than those of SCB and NS treatment, respectively. The growth and yield of cherry tomato fruits was highest with NS treatment. The yield indices of cherry tomato treated with NS+MS treatment and SCB+NS+MS were 97% and 94% of NS treatment. In conclusion, it seems to be possible to produce micronutrient-fortified cherry tomato by the mixed treatment of electrolyzed micronutrients.

The effects of cooling rate on the microstructures, precipitation of Cu-cluster, .epsilon.-Cu and impact toughness of high strength low alloy(HSLA) steel were studied using hardness tester, impact tester, DSC(differential scanning calorimetry), AES(auger electron spectroscopy) and TEM(transmission electron microscopy). Not only the Cu-precipitates but also the segregation of Cu, As, Sb, P, S, N, Sn along grain boundary were not observed at the specimens heat treated from 800.deg. C to 300.deg. C with the cooling time of 12-125 sec. The Cu-cluster, .epsilon.-Cu are formed by introducing ageing after cooling and the effect of precipitates on hardening increase after cooling was the same in all cooling rate. The peak hardness was obtained at an ageing of 500.deg. C in all cooling conditions. The impact energy become higher as the cooling time increases. This fact can be explained to be due to the tempering effect applied on the cooling stage since the present alloy has a relatively high Ms temperature and the local high concentration of the retained austenite.

본 실험에서 PET 위 무전해 구리 도금을 위한 전처리 방법 중 하나인 UV 조사를 통해 전처리를 한 후 PET 표면의 특성과 염기성 무전해 도금액이 개질된 표면에 미치는 영향에 관한 연구를 하였다. 일반적으로 PET 표면을 개질시키기 위해 UVC(254nm) 파장을 이용하여 PET bond break (Chain Scission)을 이루는 것으로 알려진다. 이때 공기 중의 산소와 UV 조사를 통해 생성된 PET 내의 free radical과 산화 반응을 통해 친수성이 높은 표면을 형성하게 된다. PET 표면의 친수성을 측정하기 위해 접촉각 측정기가 사용되었으며, 표면의 거칠기 및 형상을 관찰하기 위해 AFM과 FE-SEM를 각각 이용하였다. 또한 PET 표면의 구조 변화는 XPS를 통해 분석을 진행 하였다. UV 조사 후 표면의 거칠기 및 친수성은 높아졌지만, 무전해 도금은 이루어지지 않았다. 분석 결과, 이는 표면에 형성된 Low Molecular Weight Oxidation Compound(LMWOC)가 염기성 수용액 내에서 용해되어 모두 씻겨 나가 표면에 형성된 Sn/Pd을 모두 떨어트린 것으로 판단되며, 위와같은 이유로 UV 조사 후 습식 공정에 적용하기 위해 표면개질 된 PET를 염기성 수용액을 통해 전처리가 필요한 것으로 사료된다.
