The purpose of this study was to assess the implications for Daejeon's business management by analyzing the impact on the management performance of human solidarity among CEOs of small and medium venture companies in Daejeon. From 20th March to 20th May 2018, 212 questionnaires were collected from CEOs of small and medium-sized venture companies in Daejeon for this study and verified using the SPSS statistics Analysis Program. As a result, the study confirmed that the "work" and "school" connection factors have positive effects on securing government projects, improving business management, acquiring the necessary information for business growth, and securing competitiveness in 4th industrial revolution era. On the other hand, the "Region or Kin-group" connection factor does not affect the management performance. The following implications were derived fromthese studies on sustainable growth and development of business in Daejeon. First, it requires a higher level of the CEO solidarity. Second, efforts aimed at building mutual trust among CEOs in Daejeon are needed to develop close relationships and strong connections. Third, each operating association established in Daejeon needs to develop various programs for building relationships among CEOs and operate programs to increase the chances of contact.

At Kwangyang bay Cu in the fishery was detected up to 1.208ppm and the level of Cu and Pb in sediment of this area were 2.13 and 4.34ppm, respectively. The contents of Hg in fishery and sediment of Yeosu bay were 0.102 and 0.032ppm. The levels of Pb in fishery and seawater of Sunchon bay were 0.039ppm and 0.013$\mu\textrm{g}$/L, respectively. At Posung bay the contents of Cd were 0.277ppm, 0.09$\mu\textrm{g}$/L and 0.08ppm in the specimens of fishery, seawater and sediment, respectively. The analyzed data of all specimens at Keamundo were very low level or undetectable. Of the 6 fishery samples, Charybdis japonica showed the upper level of Hg, Cu, Zn, Mn as 0.092, 1.905, 6.64, and 46.34ppm, respectively. The contents of Pb and Cd in Batillus cornatus were 0.045 and 0.38ppm respectively and other fishery had low level of heavy metal. In this study the contents of heavy metals analyzed in all specimens showed nearly natural occurrence level which is under the legal limits.

This paper investigates how TMT's cognitive traits affect R&D investment. Drawing on the attention-based view, we propose that TMT's future orientation and risk preference increase the level of R&D investment. As R&D activities have long-term goal of generating proprietary knowledge, it is important to understand how TMT's attention toward future and risk affect R&D investment. Also, we test the moderating effect of CEO duality on R&D investment. As the CEO plays a leadership role in the TMT, if the CEO's decision-making authority is highly concentrated, the impact of TMT on R&D may decrease. We measure CEO duality and CEO ownership stake as CEO characteristics. Based on a sample of 837 U.S. manufacturing firms, the results show that when TMT has a higher tolerance for risk and higher future orientation, R&D intensity increases. However, when CEO also serves as chairman of board and CEO has higher ownership, TMT's influence on R&D investment weakens. This implies that TMT and CEO has power dynamic that can change based on CEO power supporting status. Overall, it suggests that TMT's attention and CEO power are important factors to improve longer-term knowledge accumulation of firm.

목적 : 뜸 연소 실험을 통해 간접구의 일종인 온구기의 연소 특성을 조사하였다. 방법 : 온구기를 유리판 위에 놓고 연소하여 50분간 온도 데이터를 수집하였다. 총 20개의 뜸봉을 연소하여 수집된 데이터를 분석하여 평균 온도, 최고 온도, 최고 온도 도달 시간, 최고 온도 지속 시간을 계산하였다. 또 혈류량을 증가시킨다고 보고된 온도($38^{\circ}C$)에 도달하는 시간, 그 이상의 온도로 지속되는 시간, C-fiber의 활성화를 통해 치료효과를 나타내는 것으로 보고된 온도($42-50^{\circ}C$)에 도달하는 시간과 그 범위 내의 지속시간을 계산하였다. 결과 : 평균 최고온도는 $50.4^{\circ}C$이고 평균 도달시간은 1,007초, 평균 지속시간은 27초였다. 평균최고 온도는 보고된 다른 간접구와 유사하였으나 평균 도달시간은 더 길었다. $38^{\circ}C$에 도달하는 평균시간은 410초이고 지속 시간은 1,813초였다. $42-50^{\circ}C$에 도달하는 평균시간은 521초이고 지속시간은 990초였다. 결론 : 온구기는 연소 특성이 보고된 다른 종류의 뜸보다 더 오랜 시간 동안 안정적인 열자극이 가능하여, 뜸치료의 임상 활용의 폭을 높일 수 있을 것으로 사료된다.

An objective method for the evaluation of eating quality of cooked noodle was established by using a specially designed shear extrusion cell of Rheometer. From the force-distance curve, the maximum force, initial force, extrusion work, and the slope were determined. In a test with Korean dried noodles made from 17 types of Australian wheat flour, the maximum and initial forces and extrusion work could represent the firm-soft and chewy character, which govern mostly the preference of cooked noodle. On the other hand, the slope could distinguish the textural changes of cooked noodle during the storage after cooking. The parameters showed significant correlation with the protein content, water absorption, development time and extensibility of flour, but no correlation was obtained with the maximum viscosity of viscogram. For the estimation of textural preference, the correlation coefficient obtained from a multiple regression analysis using the maximum viscosity of viscogram and the maximum force of shear extrusion test as the two independent variables was not significantly higher than the coefficient obtained from a simple regression with the maximum force only.

This research analyzed the peak impulsive force, maximum velocity and a spot of fist's maximum velocity comparing stop-jirugi and push-jirugi. 7 males volunteered for this experiment. peak impulsive force was measured by PS2142 force platform[10], and maximum velocity of fist was measured by PS2103A motion sensor[12]. All of data was collected in the data studio and t-test was applied using SAS 9.1 package. The following conclusions were drawn. First, stop-jirugi's peak impulsive force was greater (P<.01) than that of push-jirugi. Second, push-jirugi's maximum velocity of fist was greater (P<.01) than that of stop-jirugi. Third, stop-jirugi's maximum velocity of fist was occurred on 69.14% of arm's length and that of push-jirugi was occurred on 75.66%. This maximum velocity spot was statistically significant difference(p<.001).

Han-Ki Choi($1803{\sim}1877$), who was a scholar in Joseon dynasty, understood geography into a synthetic category of chorography, cartography, earth science and fengshui. He focused on chorography and map as a leading position in geography. The purpose of the research of Han-Ki Choi was to examine the way of Heaven, and then to make clear the way of Humanity. The identity of the geography for Han-Ki Choi was a practical science that useful for the ruling over the country and the welfare of people. He emphasized the nature of relationship with humans in geography. The system of Han-Ki's Chi-hak came from the basis of a geography, on the contrary, his geographical works were accomplished on the ground of the Chi-science. The chorography, Chi-hak of the earth and the earth science were composed into systematic organization for achieving the goal of the Chi-geography.

본 논문에서는 바둑판을 촬영한 정지 영상에서 격자무늬의 특징을 이용하여 바둑판의 최외각 네 점을 검출하는 방법을 제시한다. 바둑판은 수평 및 수직 방향으로 각각 19 개의 선이 격자무늬를 이룬다. 영상에는 일반적으로 노이즈가 포함되어 있기 때문에 허프(Hough) 변환의 임계값(threshold)을 이용한 선 패턴 추출 방식으로는 모든 선에 대한 정보를 얻을 수 없다. 따라서, 제안하는 알고리즘은 허프(Hough) 변환을 수행한 뒤에 추출된 선들이 이루는 교차점의 정보를 이용하여 바둑판의 최외각 네 점을 예측한다. 실험 결과는 실제 바둑판의 최외각 네 점과 비교하여 예측된 최외각 네 점의 에러 값을 제시한다. 이는 제안된 알고리즘이 바둑판의 최외각 네 점을 성공적으로 검출한다는 것을 입증한다.
