날이 샐 무렵 멀리있는 작은 별들이 자취를 감출 때 서쪽 하늘에 밝게 빛나는 큰 별 속칭 샛별이라는 그 별이 바로 화성이다. 사람들의 눈에 띄기 어려운 시간에 크게 나타나는 별이기 때문에 달처럼 친숙한 많은 이야기는 없지만 인공위성을 띄우고 달나라에 사람을 보내고 달 표면에 흙을 가져온 지구인의 과학은 드디어 화성 탐사에 도전하게 되었다.

경기도 화성시에 위치한 명동목장(목장주 최예용 서미선)은 '소가 편안한 목장'으로 불린다. 번식관리와 사양관리에 철저를 기한 덕분에 3년 만에 60두에서 120여 두(착유우 60여 두, 육성우 40여 두 등)로 사육두수도 크게 늘었으며, 체세포 1등급을 지속적으로 유지하고 있다는 명동목장의 운영비결을 들어보았다.

This study validates if this relationship results in differences of significance levels between first time and repeat visitors and analyzes if there exist any differences in the spatial characteristics of tourist attractions using Social Network Analysis(SNA) for the spacial attributes of movement network Focusing on Hwaseong city, South Korea. It is important for balanced development between tour sites in Hwaseong by enhancing the value of tourism resources and applying the concept of hub-and-spoke tourism development. Based on the analyzing the centrality of tourist movement networks, degree centrality, closeness centrality, and betweenness centrality all did not show much variation for 20 tourist attractions versus the top five. That is, the attractions that both first time and repeat visitors visit are concentrated in well-known, famous places. The authors hope that this study, which defines practical interactions among attractions based movement, will be used as practical data for developing tourist retention marketing strategies.

Extrusion cooking treatment was compared with autoclaving/cooling treatment for formation of enzyme resistant starch of high amylose corn starch (HACS). Effects of barrel temperature $(100^{\circ}C,\;120^{\circ}C,\;140^{\circ}C)$ and feed moisture content (25%, 35%, 45%) on extrusion processing in a co-rotating twin-screw extruder under fixed screw speed (100 rpm) were investigated by measuring enzyme resistant starch (RS) yield. RS yield were estimated by in-vitro pancreatin digestion method and enzymatic-gravimetric method using termamyl. Barrel temperature and yield of RS were negatively correlated and feed moisture content and yield of RS was positively correlated as determined by in-vitro pancreatin method. The highest yield (38.4%) of RS was obtained from HACS extrudate processed at the barrel temperature of $100^{\circ}C$ and the feed moisture content of 45%, while the yield of RS by 5 times of autoclaving/cooling was 25%. The yield of RS by in vitro pancreatin digestion method was 20.7% with high amylose corn starch and 8.2% with ordinary corn starch (CS), respectively, under the same extrusion condition (barrel temperature $120^{\circ}C$, feed moisture content 35%). At the same condition, the yields of RS by enzyme-gravimetric method were 14.6% with HACS and 6.8% with CS, respectively. The yield of RS increased during the storage at $4^{\circ}C$ for 4 weeks and the highest yield (60%) was obtained by the storage of HACS extrudates extruded at $100^{\circ}C$ and 45% feed moisture content.

AP통신은 평소 6000만 마일 떨어져 있는 지구와 화성 간의 거리가 우리나라 시간으로 8월 27일 오후 6시 51분에 3460만 마일까지 좁혀졌다고 밝혔다. 태양과 화성을 잇는 일직선상에 지구가 위치하는 행성직렬현상(Grand Alignment)은 대략 2.2년을 주기로 발생하며 '대접근'은 15년마다 다가온다. 하지만 이번 대접근은 특별하다. 네안데르탈인이 지구를 지배하던 BC 57617년 9월 12일 이래 약 6만년만에 찾아오는 대접근 중에서도 최대접근에 해당한다. 게다가 이들 두 행성은 오는 2287년 8월 28일에 가서야 다시 가까워지므로 살아있는 지구인이 이런 장관을 지켜볼 수 있는 것은 이번이 마지막 기회이다. 이를 계기로 미국 · 유럽 · 일본은 화성탐사에 나섰다. 그 현장을 소개한다.

The purpose of this study is to decide the optimal location site of the agricultural wholesale market in Gyeonggi-do. In this paper, methods of social network analysis are adopted to calculate the betweenness centrality, degree centrality, prestige centrality. Methods of social network analysis can be a good alternative to discover characteristics of a complicated method by visualizing relationships among nodes(cities). The results of this study are as below : First, the result of social network and present locations are not so different. Second, optimal locations of the agricultural wholesale market in Gyeonggi-do are Pyeongtaek-si, Suwon-si, Ansan-si, Seongnam-si, Hwaseong-si, Yongin-si, Icheon-si, Anyang-si etc.
