In this paper the authors deal with functional equations which is a good research topic for high school students. In particular, they consider the Cauchy equation, Pexider equation, Jensen equation and logarithmic functional equation satisfied in the complements of rhombi or in the half planes, and find the general solutions and the regular solutions of the equations.

The purpose of this study is to verify the correlation between leader's machiavellianism and turnover intention. To this end, we tried to investigate the overall mechanism of the research model through the mediating effect of hindsight bias. To verify the hypothesis, surveys were conducted twice with 335 employees working at companies with more than 300 employees in various occupations. As a result of the study, first, it was found that the machiavellianism of the leader had a positive significant effect on the employee turnover intention. Second, it was found that hindsight bias had a positive significant mediating effect between the leader's machiavellianism and employee turnover intention. It can be inferred that the higher the machiavellianism tendency of the leader, the higher the hindsight bias is experienced and the negative impact on the effectiveness of the organization, the higher the employee turnover intention. Therefore, this study in-depth verifies the mechanism between the leader's machiavellianism, hindsight bias, and employee turnover intentions, suggesting new implications from a perspective different from the existing research flow, and suggesting future research tasks and limitations on the role of leaders.

The purpose of this study is to examine whether the local traditional market can be recognized as a category of cultural landscape, and furthermore, to establish a foundation for market revitalization by exploring the possibility of various institutional support and protection for cultural heritage. It is rare that traditional markets have been approached as cultural landscapes. This is due to the limited definition and application of the concept of cultural landscape. However, as suggested by UNESCOs concept of ‘World Heritage Cultural Landscape’ and the ‘European Landscape Convention’ of the Council of Europe, it is a tradition that guarantees the history and culture of the region in that it has the potential to become a target if it is a landscape that reveals the identity of the region. The market can be recognized as a cultural landscape. Above all, the sense of community inherent in the market space can act as a condition for understanding the market as a cultural landscape and subsuming it into the category of intangible cultural heritage. From this standpoint, Daegu Seomun Market has grown together with the Daegu city and captured the twists and turns of Daegu and Korea’s modern and contemporary history. The cultural landscape that guarantees the spatiality of Seomun Market, which has been transformed into the central space of the Hyangsi area, the strategic space of colonial rule, the economic space that led the growth of Daegu, and the commercialized space with new values, is a place to understand Daegus own identity. can be the basis. The discussion on the application of the traditional market concept of the cultural landscape concept is another way to vitalize the traditional market by establishing the institutional support background for the preservation and utilization of the traditional market in addition to the expansion of the field of market research and the category of cultural heritage. could be an approach.

우리가 살아가는데 있어서 가장 기본적인 기능 중 하나인 감각적 자극은 우리의 삶 전영역에서 매일 작용하고 있다. 그래서 마케터들은 이런 감각의 중요성을 인식하게 되었고, 이 중 특히 촉각이 중요시 되면서 촉각에 대한 제품의 속성을 강조한 터치 제품들이 지속적으로 출시되고 있지만 정작 촉각이 제품의 평가에 어떠한 경로를 통해서 영향을 미치는지에 대한 연구는 미비한 실정이다. 따라서 제품을 접촉할 때 생기는 통제감과 속도감이 실재감, 관여도, 친밀도, 제품평가에 어떠한 영향을 미치는지 알아보았다. 연구 결과, 통제감과 속도감 중 제품 접촉의 통제감은 실재감에 영향을 미칠 것이라는 가설은 기각되었다. 하지만 제품접촉의 속도감은 실재감에 영향을 미치는 것으로 나타났다. 그리고 실재감은 제품의 관여도와 친밀도에 영향을 미치는 것으로 나타났다. 또한 제품에 대한 관여도는 제품 평가에 긍정적인 영향을 미치고 있는 것으로 나타났다. 하지만 제품에 대한 친밀도는 제품 평가에 긍정적인 영향을 미칠 것이라는 가설은 기각되었다. 이와 같이 속도감은 실재감에 영향을 미치며 이는 제품의 관여도와 친밀도에 영향을 주고 나아가 관여도는 제품평가에 영향을 미친다는 알 수 있었다. 따라서 본 연구는 마케터들이 터치 제품에 대한 긍정적인 평가를 이끌어 낼 수 있는 이런 속성들을 잘 파악해 마케팅 전략을 수립해야 한다는 데 의의가 있다. As we belong to our modern lives, the sensibility stimulation among the most basic functions works in our whole parts of every single day. The marketers had recognized throughout the importance of the sensibility; especially there are continuously a huge of latest releases with the great sense of touch, but no where any professionals studied hard about the effects of sensibility on the evaluation of the products through any routes. Therefore, this study is about how the sensitivity and the velocity affect when using the new products presence, involvement, intimacy and product evaluation. In this research only the people having chances to use with the touch products answered on the survey, and all the data from the collected papers show into descriptive statistics, reliability analysis, and factor analysis throughout SPSS 12.0 version. Also, there has been using path analysis with AMOS 4.0 to verify a hypothesis. The results of this study are following below. It is rejected that there is a hypothesis between sensitivity and velocity set up with the independent variable to affect the sensitivity of touch product to the velocity. But the velocity of the touch products has an effect into the presence. And the presence influences into involvement of the products and intimacy. More, the involvement of the products points at positive aspects on the product evaluation. However, it is rejected the hypothesis that the intimacy of the products looks at good effect on product evaluation. Likewise, velocity affects presence. It also means the involvement of the product and intimacy, so the involvement affects the product evaluation. Thus, this research offers that it is significant to establish marketing strategy from the marketers who bring out positive evaluation on touch product to figure out the attributes.

점도측정법을 이용한 방사선 조사 건조농산품의 검지 가능성

방사선 조사된 건조채소류, 인삼, 향신료 등을 대상으로 시료의 전분 함량과 점도를 측정함으로써 방사선 조사 여부 확인방법을 연구하였다. 대상 시료 10종의 전분함량은 15.64~60.86% 범위로 전분함량과 점도의 크기는 비례하지 않았다. 양배추, 당근, 청경채, 마늘, 버섯, 파, 고춧가루 등은 감마선 조사선량과 점도의 변화간에 유의성을 보이지 않았으나 건생강(R²=0.9271), 백삼(R²=0.6223) 및 건양파(R²=0.7909)는 유의적인 관계를 나타내었다. 따라서 방사선 조사선량의 증가에 따라 점도가 비례적으로 감소하는 생강과 인삼을 대상으로 조사 여부 판정을 위한 specific parameter를 설정하였다. 생강과 인삼 시료에 대한 비조사구의 specific parameter는 13.31과 13.93이었고, 감마선과 전자선 조사 시료(2.5 kGy, 최저 실용선량)의 specific parameter는 생강이 11.92와 11.15, 인삼이 4.40과 5.10으로 나타났다. 이상의 결과에서 볼 때 생강, 인삼 등 전분질 식품은 방사선 조사선원에 관계없이 specific parameter의 변화가 유의적임이 확인되어 미지시료의 방사선 조사 여부 검지에 활용가능성이 인정되었다. Dried vegetables, white ginseng and spices, which were exposed to gamma and electron-beam irradiation, were used in a detection study by measuring their starch content and viscosity change. The samples tested showed different levels of starch content(15.64~60.86%), which was not directly proportional to the viscosity of the samples. The correlation coefficients between irradiation dose and viscosity change were lower in the samples, such as cabbage, carrot, clean vegetable(Chunggyungchae), garlic, mushroom, green onion, and red pepper, while some higher coefficients were found in ginger(R²=0.9271), white ginseng (R²=0.6223) and onion (R²=0.7909). Thus, dried ginger and white ginseng were selected to be used for a detection of irradiated samples using specific parameters(threshold values). Specific parameter for the nonirradiated ginger and ginseng were 13.31 and 13.93, respectively. On the other hand, gamma and electronbeam irradiated samples at 2.5 kGy, the lowest dose for a commercial purpose, showed decreased values, 11.92 and 11.15 in ginger, and moreover 4.40 and 5.10 in ginseng. It is expected that a proportional decrease in a specific parameter with the absorbed doses will be a potentially useful index for detecting whether starchy foods have been irradiated or not.

본 논문에서는 꽉찬 받침을 갖는 함수의 후리에변환에 관한 전개공식인 Kotel'nikov 공식을 초함수로 확장한 공식(참고문헌[I])을 더욱 일반화하여 임의차원의 복소수 공간까지 확장하였고 동시에 [I]에서 증명한 공식보다 훨씬 간편하고 유용한 공식을 얻었다. 우리의 공식을 이용하면 꽉찬 받침을 갖는 초함수의 후리에변환은 일정한 간격을 갖는 실공간위에서의 격자점 위에서의 값만으로 완전히 결정됨을 알 수 있고 그 간격은 초함수의 받침의 크기와 관련이 있음을 알 수 있다. 또한 이 결과를 이용하여 적당한 증가도를 만족하는 Cⁿ상의 복소해석함수에 대한 항등정리를 얻었다.
