호텔웨딩연회상품의 BTL마케팅 요소, 브랜드 태도, 구매의도간의 관계 연구
황성식(Sung Sik Hwang),박철호(Chul Ho Park),한수정(Su Jung Han) 한국관광연구학회 2013 관광연구저널 Vol.27 No.4
This study attempted to suggest a new marketing strategy and provide directivity in applying it concretely for the hotel wedding-event business so that BTL marketing could be used more effectively. The theoretical structure model suggested in this study was composed of three latent variables in total, such as BTL marketing elements, brand attitude and purchase intention. By using BTL marketing elements of hotel wedding-event products on the basis of the results of those analyses, the research could bring about practical suggestions on the purchase intention as follows: 1. hotels should endeavor to develop wedding event programs for the development of various hotel wedding-event products and the establishment of a single concept. 2. in addition to the development of leading wedding programs in the wedding industry, hotel wedding companies are needed to provide customers with truly differentiated wedding service with high quality. A number of marketing implications were suggested on the basis of the findings of this paper.

Neutron dose level at bottom head of a reactor pressure vessel (RPV) was calculated using reactor vessel neutron transport for a Korean nuclear power plant A. At 34 EFPY with a 40-year (2042) design life after plating repair, irradiation fast neutron effect was 6.6x10<sup>15</sup> n/Nuclear power plant, Corrosion of RPV steel, Ni plating, Neutron effect, He generation. As helium(He) gas can be generated by Ni only at 1/10<sup>6</sup> level of 5 × 10<sup>21</sup> n/㎠, He generation possibility in the Ni plating layer is very little during 40 years of operation (2042, 34 EFPY). Thermal neutrons can significantly affect the generation of He from Ni metal. At 10 years after a repair, He can be generated at a level of about 0.06 appm, a level that can add general welding repair without any consideration. After 40 years of repair, 9.8 appm of He may be generated. Although this is a rather high value, it is within the range of 0.1 to 10 appm when welding repair can be applied. Clad repair by Ni electroplating technology is expected to greatly improve the operation efficiency by improving the safety and shortening the maintenance period of the nuclear power plant.
교육수준, 직업 및 지역에 따른 이민자 수용태도의 편차: 규범의식과 현실위협인식의 효과

이 연구는 규범이론과 현실위협이론의 이론적 논의를 확장하여 사회·지리적 요인에 따른 이민자 수용태도의 편차를 설명하고자 한다. 보다 구체적으로, 이 논문에서는 교육수준, 직업 및 거주 지역에 따른 이민자 수용태도의 편차가 규범의식과 현실위협인식 중 어떠한 내적 요인에 의해 추동되는지를 파악하고자 하였다. 분석을 위하여 이민자에 대한 내국인의 인식 및 태도에 관한 『2018 국민다문화수용성 실태조사』를 활용하였다. 분석 결과, 교육수준 및 직업지위가 높은 집단일수록 이민자 수용에 대하여 호의적인 태도를 보이는 것으로 나타났다. 교육수준은 규범의식을 높임으로써 이민자 수용태도에 영향을 미치는 반면, 직업지위는 현실위협인식을 낮춤으로써 이민자 수용태도에 영향을 미치는 것으로 밝혀졌다. 아울러 거주 지역에 따라서도 이민자 수용태도에 유의한 편차가 관찰되었다. 영남지역의 경우 규범의식이 다른 지역들에 비하여 낮게 나타났으며, 이에 따라 이민자 수용태도 또한 낮은 수준을 보였다. 한편, 호남지역의 경우 현실위협인식이 높게 나타남에 따라 이민자 수용에 대하여 부정적인 태도를 갖는 것으로 밝혀졌다. 이러한 결과는 교육수준이나 직업, 지역에 따른 이민자 수용태도의 차이가 각기 다른 내적 요인에 기인할 수 있음을 시사한다. Extending the normative consciousness and perceived threat theories on individual’s attitudes, this paper explores how socio-geographic factors influence the inner mechanisms of individual’s attitudes toward immigrants in South Korea. It is hypothesized in this study that the contrasting effects of normative consciousness and perceived threat can be incorporated in explaining the educational, occupational and regional variations in attitudes toward immigrants. Using micro-data from the 2018 National Multicultural Acceptability Survey, this study conducted a series of regression analyses to examine and compare the mediating effects of normative consciousness and perceived threat between socio-geographic factors and attitudes toward immigrants. Results of analyses show that those with more education and high occupational status tend to have favorable attitudes toward immigrants. It is found that education has a positive effect on the level of normative consciousness, while occupational status is negatively associated with the level of perceived threat. Significant geographic variations in the attitudes toward immigrants are also observed between Youngnam and Honam regions in particular, which can be mainly explained by socioeconomic, structural and cultural traits of the regions. Theoretical and policy implications of these findings are discussed in this paper.
원자력발전소 증기발생기 Alloy 690 전열관 재료의 규칙화 반응
황성식 ( Seong Sik Hwang ),최민재 ( Min Jae Choi ),김성우 ( Sung Woo Kim ) 한국부식방식학회 2023 Corrosion Science and Technology Vol.22 No.3
Considering the case in the United States where most nuclear power plants with an initial design life of 40 years continue to operate until 60 or 80 years after undergoing material soundness evaluation, it is time to plan a more robust long-term operation strategy for nuclear power plants in Korea. There are some reports that SRO/LRO might be formed when Alloy 690 is heat treated for 10,000 hours to 100,000 hours at 360 to 450 ℃. The possibility of LRO formation in Alloy 690 steam generator tubings of Kori nuclear power plant unit 1 (Kori-1) was investigated using existing research papers. The mechanism in which SRO/LRO occurred was also surveyed. Alloy 690 was found to be more likely to cause ordering than Alloy 600 in terms of alloy composition. The ordering could be evaluated through changes in material properties. However, it is difficult to evaluate it from a microstructural point of view. The likelihood of LRO in Alloy 690 of the Kori-1 plant operated at 320 ℃ for 19 years seemed to be low in terms of time and exposure temperature.
원자로 내부구조물 균열개시 민감도에 미치는 영향인자 고찰

To safely operate domestic nuclear power plants approaching the end of their design life, the material degradation management strategy of the components is important. Among studies conducted to improve the soundness of nuclear reactor components, research methods for understanding the degradation of reactor internals and preparing management strategies were surveyed. Since the IGSCC (Intergranular Stress Corrosion Cracking) initiation and propagation process is associated with metal dissolution at the crack tip, crack initiation sensitivity was decreased in the hydrogenated water with decreased crack sensitivity but occurrence of small surface cracks increased. A stress of 50 to 55% of the yield strength of the irradiated materials was required to cause IASCC (Irradiation Assisted Stress Corrosion Cracking) failure at the end of the reactor operating life. In the threshold-stress analysis, IASCC cracks were not expected to occur until the end of life at a stress of less than 62% of the investigated yield strength, and the IASCC critical dose was determined to be 4 dpa (Displacement Per Atom). The stainless steel surface oxide was composed of an internal Cr-rich spinel oxide and an external Fe and Ni-rich oxide, regardless of the dose and applied strain level.
