To develop customized food products for gastric cancer patients, it is crucial to understand their dietary characteristics and changes in their perception of smell and taste due to their condition. This study conducted in-depth interviews and administered olfactory and gustatory tests on 20 patients with gastric cancer. A control group of 20 healthy, gender and age matched individuals, was included for comparison. Patients reported difficulties in sustaining their appetite, particularly during chemotherapy. This could be attributed to gastrointestinal discomfort and an altered perception of smell and taste. The olfactory test revealed that cancer patients were significantly less sensitive than the control group. Also, a smaller number of participants in the cancer group were reported to have a normal taste function, which enabled them to perceive umami, one of the five basic taste compared to those in the control group. These findings demonstrated that gastric cancer patients experience post-surgical digestive issues, chemotherapy-induced changes in smell and taste, and appetite loss. To improve the quality of life of these patients and the efficacy of the treatment, it is necessary to consider not only their nutritional requirements but also other factors such as appetite loss and discomfort when developing meals specifically for them.

In the retail environment where online-shopping malls are growing, offline store are find it difficult to survive simply by selling their products. As a result, offline retailers are trying to find unique services that are appealing to their customers. In such a market environment, marketing strategies that stimulate the five senses other than the sight can be an alternative. Therefore, this research is aimed at observing the effect of the senses on emotion and purchase intention in a fashion retail context. A two by two experimental design (existence vs non-existence of scent x existence vs. nonexistence of eating chocolate) between subjects was used. A total of 120 participants were randomly assigned to the four situations, and they were asked to complete the questionnaires about emotion and purchase intention. The survey data were statistically analyzed using SPSS 23.0, and results are as follows. After a two-way ANOVA, we observed a statistically significant effect of the scent service on pleasure and purchase intention the sweet offering service on purchase intention. Moreover, when scents service and sweet offering service were provided at the same time, the highest purchase intention was obtained among other services. In addition, we studied the effects of emotions on purchase intentions, and the pleasant emotions resulting from the services have a positive effect of on purchase intentions.

지구온난화가 가중되고 도시가 고도화되면서 우리나라 대도시는 여름철 도시열섬이 빈번히 발생하고 있다. 특히 도심부 도로포장의 대부분을 차지하는 아스팔트 포장은 태양광을 흡수하여 노면온도를 상승시키고 야간에 복사열을 배출함으로써 열대야(최저기온이 25℃ 이상 지속)를 발생시키는 주요 원인이 된다. 이러한 도시 열환경 특성은 노약자 건강을 저해하고 시민의 생활불편을 야기하기 때문에 적극적인 개선방안이 필요하다. 이에 일본에서는 2003년부터 ‘환경포장 동경 프로젝트’ 일환으로 차열성 포장이 대안으로 검토되었다. 유럽의 경우 알베도(Albedo)가 높은 골재를 섞은 포장 재료에 대한 연구가 진행되고 있다. 국내에서도 2005년 정부 연구과제로 반사형 도료를 이용한 열섬저감 포장공법이 진행되었으며, 서울시에서는 2009∼2010년 아크릴계 반사형 도료를 이용한 차열성 포장을 개발하여 시험시공을 실시하였다. 일본과 국내에서 차도에 주로 사용하는 MMA(Methyl Methacrylate)계 반사형 도료는 독특한 냄새 때문에 도심 도로에서 넓은 공간 시공 시 주변 도로 이용자에게 불쾌감을 야기한다. 따라서 현장 적용 시 민원발생 우려가 많으므로 MMA와 같은 반사형 도료의 냄새를 저감하고, 이를 평가할 수 있는 방법에 대한 연구가 필요한 실정이다. 본 연구에서는 기존 MMA를 저취형으로 개량하기 위하여 벌크형 중합반응이 아닌 에멀전 중합반응(또는 수용성)으로 MMA를 형성하였다. 이로 인하여 기존 MMA에 비해 내구성과 내마모성이 낮아진 것을 보완하기 위하여 외부 환경에 따라 쉽게 구조가 파괴되는 단량체(Monomer)의 일부를 폴리머(Polymer)로 대체하였다. 다양한 구성비에 대하여 시험한 결과 단량체와 폴리머의 비율이 1 : 3인 경우 최적인 것으로 나타났다. 또한 환경부 악취물질 관련기준과 평가방안(공기희석 관능시험법, KS Q ISO 5496)을 반사형 도료에 대한 정량적 냄새평가 방안으로 제안하였다. 제안된 평가 방안으로 개발된 반사형 도료와 기존 미끄럼방지 포장용 도료를 비교평가 한 결과, 기존 미끄럼방지 포장용 도료의 경우 희석배수가 약 1,442인 반면 개발된 도료의 경우 희석배수가 10 이하로 무취에 가까운 저취형으로 확인되었다. 이를 토대로 향후 반사형 도료에 대한 냄새평가 및 현장적용 가능 여부 판단에 대한 기초자료로 활용될 것을 기대한다.

The residents'odor complaint is steadily increasing by odor causing from sewage system. A current drainage facilities and septic tank are included in the individual sewerage according to Sewerage Act. However, definitions and legal standards of drainage tank are insufficient. In addition, specifications and maintenance standards related to structure and size are not established.In this research, effect of drainage tank in individual sewage facilities on the odor occurrence was studied and the concentrations of H2S and composite odor were measured.From the measurements, the concentration of H2S and composite odor were 1 ppm ~ 5 ppm and 1.04 OU ~ 4.05 OU, respectively, before pump operation. Also, the concentration of H2S and composite odor were 5 ppm ~ 33 ppm and 5.10 OU ~ 35.04 OU, respectively, after pump operation. The concentration of SS in the effluent from drainage tank was ranged from 840 mg/L to 1,980 mg/L. These high concentration of SS seemed to be the major source of foul smell when high concentrated suspended solids in the public sewerage system were decomposed and then emitted.In this research, correlation coefficient (R2) between H2S and composite odor before and after pumping were 0.925 and 0.918, respectively.

We studied the relationship between a civil affair occurrence of bad smell and meteorological conditions around Seongseo district for recent 2 years. The results were as follows; (1) The civil affair occurrence days of bad smell were concentrated from May to August. (2) Daily mean temperatures were mostly 20～28℃ and daily mean relative humidities were 60～80%. (3) Wind speeds were mostly less than 2m/s(75%), and wind directions were southerly winds(50%). It was hardly occurred for relatively well-ventilated conditions in cases of wind speeds 2m/s over. And the Lagrangian particle dispersion model were used to figure out the transport route in a civil affair occurrence days of bad smell. It was found that the south-western winds transported the bad smelling materials from Jungni-dong(the place of source) to the housing complex located along a piedmont district.
