Korean peoples have been the god of "Cho-Wang" and believed the god that controll the food in the kitchen and well-being of home. There were many charms related to the kitchen. The striation, of "Kama" was especially peculiar in the charms. The word of "Kama" means hair striation of head and also means cooking kettle. Other charms related to food were also reviewed.

Persistent Extreme Temperature Events (PETEs) are defined in two steps; first, to define extreme temperature events, the 80th and 20th percentiles of daily maximum and minimum temperature were chosen. Then individual PETE was defined as an event which lasted three or longer consecutive extreme temperature days. In this study, we examined characteristics and changes of PETEs in Republic of Korea (ROK) using 14 weather stations with a relatively long-term period of data, 1954-2016. In ROK, PETEs lasted four-five days on average and occurred two-three times a year. PETEs lasted longer in summer than in winter and in maximum temperature than in minimum temperature. PETEs which lasted greater than seven days account for a greater proportion in summer than in winter. However, intensities of PETEs were greater in winter because of a larger temperature fluctuation. In both summer and winter, durations and intensities of persistent extreme high temperature events increased while those of persistent extreme low temperature events decreased. Changes of PETEs were closely related with both global warming and diverse large-scale climate variabilities such as AO, NAO and Nino 3.4.

This paper introduces the case studies of launch environmental test for cube nanosatellites and lessons learned of the design and integration from those. Generally, nanosatellites are launched and deployed in space while being contained in nanosatellite deployers, mechanical loads of launch are transferred through the deployer. This characteristic make nanosatellites under larger loads and higher possibilities of mechanical failure. This study represents guidelines of the design and the integration of the nanosatellites by showing the cases of launch environmental test of nanosatellite system. Moreover, it is suggested that the modern nanosatellite deployer with the capability of fixing the internal nanosatellite be preferable to conventional deployer by comparing the test results with those deployers.

External corrosion of buried pipes can be controlled using both coating and cathodic protection. However,deterioration of the coating can occur due to several reasons. The detection reliabilty of coating flaw detectionmethods is affected by interference such as metal objects connected to rectifiers and copper grids. Whenperforming parallel direct current voltage gradient (DCVG) inspection, a sine wave form without potentialreversal in voltage gradient appears in the area where the interference exists. However, this area may benot identified using existing methods. The objective of this study was to determine the effect of analyzingdirection on the reliability of coating flaw detection of pipes buried in soil using a multi-electrode detector. DCVG on the buried pipe was measured along the buried pipe. This measurement parallel to the pipe wasrepeated. Measured data were analyzed for parallel, vertical, and diagonal directions. The reliability of coatingflaw detection was improved by up to 46.4% compared to the conventional method.

연구성과를 향상시키는 데 중요한 요인은 연구자의 역량, 연구비 등의 자원 투입 등이 지적되었다. 하지만 최근에는 공동연구가 활성화되면서 연구자 사이의 구조적 특성을 통해 지속적 상호관계를 형성하여 과학적 지식을 생산하고 있기 때문이다. 하지만 이러한 연구비 지원이 지원 자체에 그치는 것이 아니라 연구비 지원으로 인해 다수의 기관이 협력하여 연구를 수행할 수 있는 발판이 된다는 점에서 연구성과에 영향을 미치는 것으로 볼 수 있다. 즉 연구비 지원이 공동연구의 연결구조에 차이를 발생시켜 연구성과에 영향을 미치기 때문으로 추정할 수 있다. SCIE DB에서 2009년부터 2013년까지 5년간 문화기술(CT) 분야의 공동연구 논문을 대상으로 연구비 지원 여부에 따른 네트워크 구조와 연구성과의 관계를 분석한 결과 다수의 연구기관이 연결되어 있을수록 논문 편수가 증가하고 사이 중심성이 증가할수록 논문 편수는 감소하는 것으로 분석되었다. 또한 연구비 지원 여부가 네트워크 구조, 연구성과에 영향을 미치는 것으로 분석되었다. As the important factors to improve research performance, the researchers' capacity and the input of resources like research funds have been pointed out. As joint researches are recently vitalized, however, the scientific knowledge is produced by forming continuous mutual relations through the structural characteristics between researchers. Since the support of research funds becomes a foothold to perform researches as multiple institutions cooperate with each other, it can be considered to have influence on research performance. In other words, it can be estimated that the support of research funds has influence on research performance by generating differences in the connecting structure of joint researches. In the results of analyzing the relation between network structure and research performance in accordance with the matter of supporting research funds, targeting the joint research theses in the culture technology(CT) area for five years from 2009 to 2013 in SCIE DB, when multiple research institutes are connected to each other, the number of thesis is increased. When the betweenness centrality is increased, the number of thesis is decreased. Also, the matter of supporting research funds has influence on network structure and research performance.
